DAMTP/96-73 SWAT/132 DISSIPATING COSMIC VORTONS AND BARYOGENESIS

Abstract Grand unified theories can admit cosmic strings with fermion zero modes which result in the string carrying a current and the formation of stable remnants, vortons. We consider theories in which the zero modes do not survive a subsequent phase transition, for example the electroweak transition, resulting in vorton dissipation. The dissipating vortons can create a baryon asymmetry. We calculate the asymmetry produced, and show that it is maximised if the vortons decay just before they dominate the energy density of the Universe. We further bound the asymmetry produced by the late decay of any relic particle.

Optimal holding temperatures and phosphorus additions for primary silicon refinement in Al-high Si alloys

AbstractThe refinement of primary silicon particles in hypereutectic aluminium–silicon alloys with exceptionally high Si contents (Al–high Si alloys) has been studied using optical microscopy, scanning electron microscopy and electron probe microanalysis. A new Si–20P master alloy has been developed which was used to study the optimal melt treating technology for achieving a satisfactory refinement of primary silicon. The experimental results show that the optimal superheating temperature and the amount of phosphorus addition increase abruptly when silicon content reaches about 50 wt-%. A few of experiential formulae are presented for the optimal superheating temperature and the amount of phosphorus addition. The refinement mechanism of the primary silicon is also discussed.

LODGrefine - LOD-enabled Google Refine in Action

As a part of LOD2 project we developed several extensions for Google Refine - a simple, yet very powerful open-source tool for working with messy data, to make LOD a first-class citizen in this tool, which is currently tightly coupled with Freebase and has no support for DBpedia. LODGrefine is a version of Google Refine with integrated extensions developed by Zemanta and DERI, adding support for rec- onciliation with DBpedia, export to RDF, augmentation of data with columns from DBpedia and extraction of entities from full text. Use of LODGrefine will be demonstrated in three use cases.

Chylothorax as Presenting Manifestation of Adenocarcinoma with Probable Gastric Primary

Chylothorax is an unusual complication of various malignant neoplasms, generally lymphomas. The few reported cases of chylothorax with gastric and other abdominal malignancies have involved large abdominal masses with prominent adenopathy and chylous ascites. We describe a patient in whom chylothorax was the presenting manifestation of an adenocarcinoma with probable gastric primary, developing prior to any clinical or radiologic evidence of tumor.

SINVI: smart indoor navigation for the visually impaired

Vision is an important sensory functionality of humans. Without which, navigation would be difficult and hazardous. In this paper, we outline the use of a novel approach to developing an automated guiding system for the blind. The approach is to use visual clues interpreted from images captured from a lightweight camera, mounted on a user. Visual clues are deciphered from the surrounding environment of the user. With just this information, the system would be able to guide the user through an indoor environment via audio cues. Majority of the visual clues would be gathered from the ceiling region. This is due to its low probability of being obscured, thereby increasing the chances of successful navigation.

The brain’s Geppetto—microbes as puppeteers of neural function and behaviour?

Research on the microbiome and its interaction with various host organs, including the brain, is increasingly gaining momentum. With more evidence establishing a comprehensive microbiota-gut-brain axis, questions have been raised as to the extent to which microbes influence brain physiology and behaviour. In parallel, there is a growing literature showing active behavioural manipulation in favour of the microbe for certain parasites. However, it seems unclear where the hidden majority of microbes are localised on the parasitism-mutualism spectrum. A long evolutionary history intimately connects host and microbiota, which complicates this classification. In this conceptual minireview, we discuss current hypotheses on host-microbe interaction and argue that novel experimental approaches and theoretical concepts, such as the hologenome theory, are necessary to incorporate transgenerational epigenetic inheritance of the microbiome into evolutionary theories.

The Specification of the Sibling Design Pattern

A hinge band with decorative links articulated about pivot pins includes a plurality of special removable links in order to adjust the length of the hinge band, for example, to fit the arm of the wearer where the hinge band holds a wristwatch or the like. The removable links have decorative insert members and partial collars. Selected links may be released by pivoting and depressing the spring retainers which hold the pins in blocking relation in the partial collars.

Data partitioning for networked parallel processing

The workstation model of parallel processing presents specific challenges caused by the latency of the communications network and the workload imbalance that arises from the heterogeneity of the nodes. Data partitioning is critically important for parallel processing in this environment. We mathematically characterize the communication costs for four data decomposition schemes: scatter, contiguous point, contiguous row, and block. These methods are analyzed in terms of problem size, number of processors, network speed, and communication pattern. Bounds are established for the performance of these decomposition schemes that can be used to make better-informed data partitioning decisions. >

FLOW BEHAVIOUR OF MODIFIED CEMENT PASTES

Abstract Rheological behaviour of modified cement pastes has been investigated by means of a planned experiment. The regressive models of paste are obtained in the form of six-factor equations. The relative influence of each factor (component) is critically analyzed. The most significant, from a rheological point of view, ingredients of cement paste, as well as their influence are presented.

History and Australian indigenous child welfare policies

The term ‘apologist’ refers to writers defending Aboriginal child-removal policies. They argue that the policies were beneficial and intended to protect children, and that systematic mistreatment never occurred and parents supported the interventions. I locate the apologetic literature in larger accounts of child welfare. Their ethical framework is established and attention is given to question of ethical relativism with specific attention to Windschuttle. While querying the empirical value of apologist writing it is argued that they produce accounts of policy that are not morally defensible, evident in their framing of events, the omission of critical material and absence of significant scholarship.

Biological Augmentation of Meniscus Repair and Restoration

Meniscus tears in the knee lead to significant pain and disability. The ability of meniscus tears to heal after repair is limited, particularly within the avascular zone. While meniscectomy is a commonly performed and a relatively straightforward treatment option, it is less desirable compared to repair as meniscus deficiency is a predisposing factor for the development of osteoarthritis. Most efforts to augment meniscal repairs in human studies have centered on the use of mechanical stimulation, fibrin clot, and platelet-rich plasma (PRP). When meniscal replacement is needed, allograft transplantation is currently the most viable treatment option. Stem cell and growth factor augmentation remain promising alternatives but require further research prior to use in humans.

Introduction to Type III Secretion Systems.

Type III secretion (T3S) systems are found in a large number of gram-negative bacteria where they function to manipulate the biology of infected hosts. Hosts targeted by T3S systems are widely distributed in nature and are represented by animals and plants. T3S systems are found in diverse genera of bacteria and they share a common core structure and function. Effector proteins are delivered by T3S systems into targeted host cells without prior secretion of the effectors into the environment. Instead, an assembled translocon structure functions to translocate effectors across eukaryotic cell membranes. In many cases, T3S systems are essential virulence factors and in some instances they promote symbiotic interactions.

Deposition of iron sulfide thin films by AACVD from single source precursors

Abstract The unsymmetrical [Fe(S 2 CNEt i Pr) 3 ] ( 1 ), [Fe(S 2 CNEtMe) 3 ] (2 ) and symmetrical [Fe(S 2 CN(Hex) 2 ) 3 ] ( 3 ), [Fe(S 2 CN(Et) 2 ) 3 ] ( 4 ) tris (dialkyldithiocarbamato)iron(III) complexes were used as single source precursors for the deposition of iron sulfide thin films by the aerosol assisted chemical vapor Deposition (AACVD) method. The unsymmetrical complexes deposited the mixed phases (pyrite and marcasite) at all deposition temperatures except the complex ( 2 ) which deposited pyrite and pyrrhotite at 400 °C. The symmetrical complex ( 3 ) with longer alkyl groups produced a mixture of pyrite and pyrrhotite phases at 350 and 450 °C but pyrite and mackinawite at 400 °C whereas the complex ( 4 ) with shorter alkyl groups deposited a mixture of pyrite and marcasite at 350 °C but a pure pyrrhotite phase at 400 and 450 °C.

Crystal structure of the reversed carboxy-analogue of acetylcholine [methyl 3-(dimethylamino)propionate methiodide]

The crystal structure of the title compound has been determined by X-ray diffraction. Crystals are orthorhombic with a= 10.948(5), b= 13.803(6), c= 7.101(2)A, Z= 4, space group Pnam. The structure was solved by Patterson and Fourier methods and refined by full-matrix least-squares to R 0.047 for 952 three-dimensional diffractometer data. The iodide and methyl 3-(trimethylammonio)propionate ions are situated on the mirror plane at z=¼, and the crystal structure therefore consists of layers parallel to (001).

Effect of mechanical milling on thermoelectric properties of half-Heusler ZrNiSn0.98Sb0.02 intermetallic compound

Abstract Thermoelectric properties of half-Heusler ZrNiSn intermetallic compound were investigated. The partial substitution for Sn site in ZrNiSn by Sb is effective for the reduction of the electrical resistivity, which leads to increase the power factor of the compound. The thermal conductivity for ZrNiSn 0.98 Sb 0.02 can be reduced by the mechanical milling process maintaining the moderate Seebeck coefficient and electrical resistivity. The reduction of the thermal conductivity is ascribed to the enhancement of the phonon scattering accompanied with the minute crystal grains in the milled compounds. As a result, ZrNiSn 0.98 Sb 0.02 with a milling time of 3 h shows a maximum ZT of 0.67 at 573 K.

Research Advances in Harmful Effects of Soil Cd Pollution on Crops

Environmental heavy metal Cd does harm to human through soil-crop-food chain. This paper summarizes factors infl uencing the Cd absorption and accumulation of crops from soils, such as crop characteristics, soil Cd contents and form distribution, soil properties, as well as water and fertilizer management. Then it reviews the effects of soil Cd on crop growth, photosynthesis and respiration, cell division and cell membrane permeability, oxidation-reduction system, enzyme activities, gene expression, and its infl uencing mechanism. On this basis, it proposes that some measures of reducing soil Cd harm to crops should be considered and practised comprehensively from every aspect and step of Cd trans ference in the food chain so as to balance the safety and effi cient utilization of Cd polluted soils as well as food safety

Evaluating the effects of cold water diffusates against Xanthomonas oryzae Pv. Oryzae causing bacterial leaf blight (BLB) in rice

Abstract The crude extracts of 63 plants were used for testing antibacterial activity against Xanthmonas oryazae Pv. oryzae that causes bacterial leaf blight (BLB) in rice plants. Only ten aqueous extracts of botanicals (Thuja orientalis, Prunus domestica, Citrus limon, Allium sativum, Vitis vinefera, Mangifera indica, Phyllanthus emblica, and Terminalia chebula) showed maximum activity against Xanthmonas oryazae in a plate agar diffusion assay. On a detached leaf, in a glasshouse and in a field assay, two potential plant extracts, namely Allium sativum, and Citrus limon showed maximum efficacy in terms of controlling BLB lesions in rice. After isolation through fractionation of the crude extract of Allium sativum, the bioactive compound was purified and characterized as 8-amino(-8-butoxyoct)-2-(enyldisulfanyl)-3-(2hydroxy-4-methoxyphenylprop-1-enyl) benzene-1,3-diol.

FOM: Fourth-order moment based causal direction identification on the heteroscedastic data

Abstract Identification of the causal direction is a fundamental problem in many scientific research areas. The independence between the noise and the cause variable is a widely used assumption to identify the causal direction. However, such an independence assumption is usually violated due to heteroscedasticity of the real-world data. In this paper, we propose a new criterion for the causal direction identification which is robust to the heteroscedasticity of the data. In detail, the fourth-order moment of noise is proposed to measure the asymmetry between the cause and effect. A heteroscedastic Gaussian process regression-based estimation of the fourth-order moment is proposed accordingly. Under some commonly used assumptions of the causal mechanism, we theoretically show that the noise’s fourth-order moment of the causal direction is smaller than that of the anti-causal direction. Experimental results on both simulated and real-world data illustrate the efficiency of the proposed approach.

[Fixed fibrous subaortic stenosis. Postoperative evaluation].

Fibrous sub-aortic stenosis in 19 patients surgically treated is discussed. The clinical, radiologic, EKG and cardiac catheterization data in the pre and post-operative evaluations are reviewed. There were no surgical deaths in this series. In 14 cases post-operative cardiac catheterization was carried out, in 11 patients a significant decrease in the gradient was found. In 4 cases pharmacological testing was done during catheterization before and after surgery, without significant change in gradients.

Experimental Study on Aerodynamic Characteristics of Telescopic Aerospikes with Multiple Disks

In this paper, experimental studies on telescopic aerospikes with multiple disks are reported. The telescopic aerospike is useful as an aerodynamic control device; however, changing its length causes a buzz phenomenon,which many researchers have reported. The occurrence of buzzing might be critical to the vehicle because it brings about severe pressure oscillations on the surface. Disks on the shaft produce stable recirculation regions by dividing the single separation flow into several conical cavity flows. Therefore, the telescopic aerospikes with stabilizer disks are useful without being any length constraints. Aerodynamic characteristics of the telescopic aerospikes were investigated using wind tunnel tests. Transition of recirculation/reattachment flow modes of a plain spike causes a large change in the drag coefficient. Because of this hysteresis phenomenon, the plain spike is unsuitable for fine aerodynamic control devices. Adding stabilizer disks is effective for the improved control of aerospikes.

Trimethyl phosphate-CCl4 interaction: experimental and computational evidence for Cl...O interactions

Abstract The formation of a weak Cl⋯O bond has been discerned both experimentally and computationally in our studies on the trimethyl phosphate (TMP)–CCl 4 system. TMP and CCl 4 were codeposited in a nitrogen matrix and adducts of these species were identified using infrared spectroscopy. Formation of the weak adducts were evidenced by shifts in the vibrational frequencies of TMP. The structures and the vibrational frequencies of these adducts were computed at the HF/6-31G ∗∗ level and the computed vibrational frequencies compared well with the observed frequencies. The nature of the bonding in this adduct was also studied using the atom-in-molecule theory, which clearly showed a (3, −1) bond critical point between the two submolecules. The stabilization energy of these adducts, were computed both at the HF/6-31G ∗∗ //HF/6-31G ∗∗ and MP2/6-31G ∗∗ //HF/6-31G ∗∗ levels after correcting for zero-point energies and basis set superposition errors.

Quasar candidates near A1139, A1775, and 1633+33

Lists of quasar candidates discovered with blue, blue green, and and green grens plates are presented, along with a discussion of the surface densities of quasars and a comparison with the 3C 345 field. The plates covered the fields A1139, A1775, and 1663+33. A total of 74 new candidate quasars were detected, with surface densities higher than usually observed with a slitless spectra technique. The 3C 345 field was filled with quasars brighter than 19 mag, although slit spectra are recommended for confirmation.

C. S. Lewis and the Art of Reading: The Uses of Scholarship and the Pleasures of the Text

C. S. Lewis was one of the major scholars of literature in the 20 th century. His contribution to the art of reading deserves a re-consideration and is therefore reconstructed and analysed in this paper. Topcis that are highlighted in this connection are the types of literary scholarship most useful to a proper understanding of old texts, the types of readers that exist, the controversies in which Lewis engaged concerning the interpretation of Milton, the importance of philological knowledge for literary scholars as well as the pitfalls of literary criticism. In many respects, C. S. Lewis is at odds with currently fashionable approaches to literature�a and thus provides a welcome challenge to dominant paradigms of reading texts.

Synthesis of two new nano-structured mercury(ll) complexes with 4-methyl-4H-1,2,4-triazole-3-thiol ligand by sonochemical method

Abstract Two mercury(II) complexes [Hg(4-mtrt)Cl 2 ] ( 1 ) and [Hg(4-mtrt)Br 2 ] ( 2 ), have been synthesized from reaction of ligand 4-methyl-4H-1,2,4-triazole-3-thiol (4-mtrt) with HgCl 2 and HgBr 2 . Structures of compound 1 – 2 have been characterized by elemental analysis, IR spectroscopy and single crystal X-ray diffraction. The nanoparticles of compound 1 – 2 have been prepared by sonochemical method. The new nano-structures were characterized by scanning electron microscopy, elemental analysis, IR spectroscopy and X-ray diffraction (XRD). The size of the samples prepared by sonochemical method are about 50 and 60 nm in compounds 1 and 2 respectively.

Binding of transferrin and uptake of iron by K-562 cells.

Transferrin-mediated uptake of iron has been studied in K-562 human erythroleukaemia cells. K-562 cells accumulate iron from transferrin by a temperature-dependent mechanism linearly with time for at least 150 min. At 37 degrees C the uptake reaches a saturation level of approximately 25 pmol iron/10(6) cells/h at a concentration of iron (as iron-transferrin) of 5 mumol/l. The binding of transferrin reveals saturation kinetics, at 0.2 mumol/l of transferrin specific binding amounts to 1.8 pmol/10(6) cells. Relative to the binding of transferrin the uptake of iron increases with time. The ability of K-562 cells to accumulate iron declines with days in culture by approximately 50% from day 1 to day 5. The results are compatible with iron uptake by receptor-mediated endocytosis of transferrin, dissociation of iron within the cell and exocytosis of apotransferrin.

An inexpensive system for continuously recording maternal behavior in the laboratory rat

Abstract A system is described for the continuous recording of time spent on the nest by mother rats. Accurate estimates of nursing time are obtained by limiting the space available for nesting and making food and water available only outside of the nesting area. The apparatus may also be used to monitor preparturient circadian activity, and to estimate the time of parturition. It is suggested that continuous monitoring of maternal nesting behavior be an important adjunct to experiments involving manipulation of the mother or litter.

Stała interpretacyjna: status rzeczy w poezji Wallace’a Stevensa

Stevens’s poems grant a curious status to material reality. Famously abstract, they refuse to abandon the realm of the material. Rather, “material reality” is inseparable from “abstract” concepts. Stevens’s position is pragmatist: the status and significance of material objects is founded by the entirely human linguistic/mental activity, which is also an interpretive activity. The poem is a site of initiating this activity. As such, Stevens’s poetics remains in opposition to other aesthetic posi­tions: the linguistic idealism of Mallarme, the metaphysical realism of Milosz and Herbert, and the material realism of Ponge and American “objectivists”. While the metaphysical positions tend to overcome the material, the realistic poets will reify it by “taking the side of things”. Stevens’s poetic pragmatism sees no lure in the extra-material, while also refusing to see matter as meaningful in itself, beyond the human interpretive activity.

A role for the acidic trimer repeat region of transcription factor sigma 54 in setting the rate and temperature dependence of promoter melting in vivo.

sigma 54 is an atypical sigma factor involved in enhancer-dependent transcription in Escherichia coli. In vivo assays were developed for following the kinetics and thermodynamics of sigma 54-dependent melting of the glnAP2 promoter start site. These assays were applied to a series of three sigma 54 polymerases containing zero, one, and two copies of the highly acidic trimer repeat region. The results showed that at least one copy of this acid region is required for a complete melting transition at physiological temperature, but is not required for a low temperature melting transition. The rate of melting the promoter in vivo increased with number of copies of this region. Taken together with other observations, the experiments point to a role for the acid region in triggering conformational changes that lead to specific promoter melting. The acid region is required for these changes to occur fully at physiological temperature and influences the rate at which they occur.

WEB APPLICATION SECURITY INSTRUCTIONAL PARADIGMS AND THE IS CURRICULUM

This document provides an overview of the growing importance of web application security threats and its role in the IS security curriculum. Two alternative instructional paradigms designed to present web application security were reviewed. Secure Programming curricula have been used to present detailed coverage from a software coding perspective. However, the Secure Programming Paradigm may present challenges in the choice of programming language or the required level of programming prerequisites that may not be appropriate for an Information Systems curriculum. As an alternative, the Automated Web Application Testing Paradigm using IBM's AppScan web security testing tool presents web application security from a quality assurance and testing perspective that may be integrated within the Software Development Life Cycle (SDLC). Recommendations for the integration of web application security in context of an Information Systems curriculum will be discussed.

Optimal stopping for measure-valued piecewise deterministic Markov processes

This paper investigates the random horizon optimal stopping problem for measure-valued piecewise deterministic Markov processes (PDMPs). This is motivated by population dynamics applications, when one wants to monitor some characteristics of the individuals in a small population. The population and its individual characteristics can be represented by a point measure. We first define a PDMP on a space of locally finite measures. Then we define a sequence of random horizon optimal stopping problems for such processes. We prove that the value function of the problems can be obtained by iterating some dynamic programming operator. Finally we prove on a simple counter-example that controlling the whole population is not equivalent to controlling a random lineage.

Expression of nectin-4 as a potential biomarker in enzootic nasal adenocarcinoma of goats.

The aim of this study was to test nectin-4 by immunohistochemistry as a potential biomarker in enzootic nasal adenocarcinoma (ENA) of goats. Twentyfour archival ENA case samples [from 14 male and 10 female hair goats (Capra hircus)] were used. The samples were stained with haematoxylin and eosin (HE). Nectin-4 expression was studied by immunohistochemistry. By microscopy, tubular, papillary, and mixed patterns of ENA were diagnosed in the cases. Immunohistochemically, the tumours showed moderate nectin-4 expression (++) in 14 cases (58.3%), strong expression (+++) in five cases (20.8%), and weak expression (+) in three cases (12.5%), while two cases (8.3%) were negative. Normal nasal tissues were not stained with nectin-4. The results suggest that nectin-4 may be used as a valuable biomarker of ENA.

Preparation, photocatalytic activities, and dye-sensitized solar-cell performance of submicron-scale TiO2 hollow spheres.

We prepared submicron-scale spherical hollow particles of anatase TiO2 by using a polystyrene-bead template. The obtained particles were very uniform in size, with a diameter of 490 nm and a shell thickness of 30 nm. The Brunauer-Emmett-Teller surface area measurements revealed a large value of 70 m2/g. The photocatalytic property was investigated by the complete decomposition of gaseous isopropyl alcohol under UV irradiation. It was indicated that the activity of the hollow spheres was 1.8 times higher than that of the conventional P25 TiO2 nanoparticles with a diameter of 30 nm. Furthermore, we fabricated a dye-sensitized solar cell (DSC) using an electrode of the TiO2 hollow spheres, and examined the photovoltaic performance under simulated sunlight. Although the per-area efficiency was rather low (1.26%) because of a low area density of TiO2 on the electrode, the per-weight efficiency was 2.5 times higher than those of the conventional DSCs of TiO2.

LABORATORY AND PILOT PLANT EVALUATION OF PRONTO URANIUM CONCENTRATE

The laboratory and pilot plant evaluation of Pronto uraniumn concentrate ts presented in this report. This concentrate mneets all FMPC Impurity tolerance limits except those for thorium and chloride. The thorium tolerance limit can be met by the addition of phosphate as required for thorium containing uranium concentrates. Blending of this material with a high-quality, low-chloride- content uranium concentrate will be necessary to lower the chloride content below the tolerance limit. Digestion and extraction tests indicate that new receipts of Pronto concentrate can be processed in the FMPC Refinery using the suggested operating conditions. That is, with the exception of a lower extract~on column pulse frequency and possibly a reduced organic product saturation to prevent excessive uranium losses in the raffinate, the standard operating conditions should be used.

On The Use of Stable Nitrogen Isotopes in Present and Past Anoxic Environments

Knowledge about the biogeochemistry of nitrogen cycling in modern aquatic ecosystems and the associated fractionations of nitrogen isotopes (δ15N) has increased significantly during the past two decades. These insights also improved our ability to interpret δ15N records recovered from ancient sediments. Specific environmental setups such as coastal upwelling areas, open pelagic realms, or stagnant basins are characterized by distinct biogenic processes and the formation of a typifying sedimentary record. We find growing evidence to recover these distinct biogenic processes in detail from δ15N patterns observed in earth history. Sediments with elevated nitrogen contents (>0.2%) and low diagenetic offprint are most suitable for such investigations. The analysis of δ15N in extracted biomarkers such as chlorines and porphyrines, or from nitrogen bearing hard parts of certain fossils offer valuable tools to assess the sample quality and a possible imprint derived from diagenesis.

Shielding Analysis of the 5320 Shipping Cask

The purpose of this work is to demonstrate that the 5320 shipping cask meets Federal regulations for maximum radiation dose rates when loaded with the intended plutonium oxide cargo. It should be emphasized that the 5320 is an existing cask, and therefore this work represents confirmatory analysis rather than design analysis.

Structural Diversity in Manganese(II) Complexes with Multidentate N‐Donor Imino Pyridyl Ligands

Four Mn(NCS)2 based compounds of the types [Mn(SCN)2(L1)]·EtOH (1), [Mn(SCN)2(L2)]·½EtOH (2), [Mn(SCN)2(L3)] (3), and [Mn(SCN)2(L4)2]n·3nMeCN (4) [L1 = benzilbis((pyridin-2-yl)methylidenehydrazone), L2 = benzilbis((acetylpyridin-2-yl)methylidenehydrazone, L3 = benzilbis((phenylpyridin-2-yl)methylidenehydrazone, and L4 = benzilbis((pyridin-3-yl)methylidenehydrazone)] were synthesized and characterized by single-crystal X-ray diffraction studies, elemental analysis, and IR spectroscopy. The first three complexes of general formula Mn(SCN)2(L1–3) consist of discrete units, whereas the fourth one consists of one-dimensional coordination polymer. The central metal atoms in 1–4 exhibit a distorted octahedral arrangement.

Inflammatory joint disease as a manifestation of Toxocara canis larva migrans

We report a case of migrating joint involvement occurring as the first manifestation of Toxocara canis larva migrans. We also reviewed the literature on joint disease caused by parasitic infections. Diagnostic criteria are described. We suggest that an immunoallergic mechanism is involved. Furthermore, the therapeutic trial with thiabendazole contributed usefully to the diagnosis in our patient.

Collaboration : integrating education and clinical practice : The Case of La Trobe University/The Alfred Clinical School of Nursing

A Clinical School of Nursing combines resources, opportunities and benefits for hospital and university staff as well as students. Collaboration is essential in the partnership between the two institutions and aspects will be explored in this paper, including antecedent conditions of organisational commitment, cooperation and trust, identification of costs, and a formal agreement. Collaboration itself is built on cooperative endeavour, willing participation, shared planning and decision making, a team approach, and shared responsibility and power. These attributes are readily identifiable in this exciting initiative.

Rapid Deployment Indoor Localization without Prior Human Participation

In this work, we propose RAD, a RApid Deployment localization framework without human sampling. The basic idea of RAD is to automatically generate a fingerprint database through space partition, of which each cell is fingerprinted by its maximum influence APs. Based on this robust location indicator, fine-grained localization can be achieved by a discretized particle filter utilizing sensor data fusion. We devise techniques for CIVD-based field division, graph-based particle filter, EM-based individual character learning, and build a prototype that runs on commodity devices. Extensive experiments show that RAD provides a comparable performance to the state-of-the-art RSS-based methods while relieving it of prior human participation.

A simpler proof of Mirzakhani’s simple curve asymptotics, Geom. Dedicata 114

Maryam Mirzakhani (in her doctoral dissertation) has proved the author's conjecture that the number of simple curves of length bounded by L on a hyperbolic surface S is assymptotic to a constant times L to the power d, where d is the dimension of the Teichmuller space of S. In this note we clarify and simplify Mirzakhani's argument.

Heteroepitaxy of Fin-Shaped InGaN Nanoridge Using Molecular Beam Epitaxy

We have demonstrated a well-ordered In-rich single crystalline InGaN nanoridge array grown on GaN/sapphire substrate using the integration of top-down etching and bottom-up molecular beam epitaxy. During the initial growth of InGaN on a patterned GaN/sapphire substrate, a (1011) r-plane predominantly forms, suppressing the growth in [1011] crystal direction and resulting in a triangular InGaN nanoprism. As the growth proceeds further, a narrow (∼50 nm) single-crystal fin-shaped InGaN nanoridge forms atop the InGaN nanoprism structure. The resulting narrow fin-shaped InGaN nanoridge structure shows extremely strong photoluminescence (PL) intensity with a center wavelength at 524–560 nm and narrow distribution compared to the epitaxially grown planar InGaN layer or InGaN nanowire. High-resolution scanning transmission electron microscopy (STEM) combined with an energy-dispersive X-ray (EDS) map reveals that a sharply faceted single-crystal InGaN nanoridge (∼50 nm width) forms along the top of each InGaN n...

APPLICATION OF SEALS, ASPHALT CONCRETE OVERLAYS, AND DEVELOPMENTAL WORK ON NONCORROSIVE DEICERS.

Changes in protein synthetic profiles during retinoic-acid induction of differentiation of murine embryonal carcinoma cells.

Analysis of two-dimensional gel electrophoretic patterns of proteins labeled with [35S]methionine was undertaken to investigate changes in gene expression in embryonal carcinoma cell line Nulli-SCC1 during the induction of differentiation in vitro by retinoic acid. The results indicate that changes in protein profiles occur long before overt morphological differentiation is observed. Studies utilizing the antimetabolite, alpha-amanitin, coupled with those involving the cell-free translation of poly(A)+ -RNA, suggest that gene expression is controlled post-transcriptionally as well as transcriptionally. In this respect, embryonal carcinoma cells appear to resemble early embryonic cells, which show evidence of multiple levels of control of gene expression during the initial stages of development and differentiation.

OPTIMAL OPERATION OF THIN FILM GROWTH WITH MULTISCALE PROCESS OBJECTIVES

Abstract The issue of optimal time-varying operation for transport-reaction processes is considered, when the cost functional and/or equality constraints necessitate the consideration of phenomena that occur over disparate length scales. Multiscale process models are initially developed, linking continuum conservation laws with microscopic scale simulators. Subsequently, order reduction techniques for dissipative partial-differential equations are combined with adaptive tabulation methods for microscopic simulators to reduce the computational requirements of the optimization problem, which is then solved using standard search algorithms. The method is demonstrated on a thin film deposition process, where optimal surface temperature profiles and inlet switching times that simultaneously maximize thickness uniformity and minimize surface roughness across the film surface are computed.

The disadvantages of jamming gates is thereby eliminated.

The application of the principles of symmetry to the synthesis of multi-coloured counterchange patterns

Attention is focused on the theoretical principles governing the underlying geometry of motifs, border patterns and all-over patterns. The systematic classification and construction of two-dimensional periodic patterns and tilings is introduced, with particular relerence to two-colour and higher colour counterchange possibilities. An identification is made of the geometrical restraints encountered when introducing systematic interchange of colour. A wide ranging series of original patterns and tilings is constructed and fully illustrated; these designs have been printed in fabric form and are presented in the accompanying exhibition.

Measurement and simulation of temperature dynamics under electron beam

An original in situ technique was developed to measure the temperature rise and decay of a material under electron-beam (e-beam) irradiation. The technique uses the effect of temperature rise on the electrical conductivity of high-temperature superconductors that are prefabricated as microbridges. This temperature sensor was measured to have a sensitivity greater than two orders of magnitude more than a thin-film thermocouple. A stroboscopic technique ensured nanosecond temporal resolution, and the size of the microbridge allowed for micrometer-scale spatial resolution. These measurement ranges are important for practical e-beam lithography. Experimental results were compared with results simulated by the TEMPTATION (temperature simulation) software, and qualitative agreement of simulated and measured results was found. Factors influencing the accuracy of the temperature measurement are discussed.

Isolation of pure sheaths of Litomosoides carinii microfilariae

A method is described for the isolation of pure, chemically intact sheaths of blood microfilariae of Litomosoides carinii. Microfilariae were isolated according to standard techniques. Exsheathment was performed by freezing-thawing-shaking procedures, repeated 5-10 times, i.e., larvae were frozen in liquid nitrogen, thawed at room temperature, and shaken vigorously for 5 s. Exsheathment rates were about 50%. Sheaths were separated from ensheathed and exsheathed microfilariae and microfilariae fragments by filtration through a polycarbonate filter (2 micron pore size). The achievable yield (about 15% of the sheaths of a batch of microfilariae) was approximately 1 microgram of sheaths per 10(6) microfilariae.

SR Proteins: Binders, Regulators, and Connectors of RNA

Serine and arginine-rich (SR) proteins are RNA-binding proteins (RBPs) known as constitutive and alternative splicing regulators. As splicing is linked to transcriptional and post-transcriptional steps, SR proteins are implicated in the regulation of multiple aspects of the gene expression program. Recent global analyses of SR-RNA interaction maps have advanced our understanding of SR-regulated gene expression. Diverse SR proteins play partially overlapping but distinct roles in transcription-coupled splicing and mRNA processing in the nucleus. In addition, shuttling SR proteins act as adaptors for mRNA export and as regulators for translation in the cytoplasm. This mini-review will summarize the roles of SR proteins as RNA binders, regulators, and connectors from transcription in the nucleus to translation in the cytoplasm.

3-Methyladenine-DNA glycosylase II: The crystal structure of an AlkA-hypoxanthine complex suggests the possibility of product inhibition

Escherichia coli (E. coli) protein 3-methyladenine-DNA glycosylase II (AlkA) functions primarily by removing alkylation damage from duplex and single stranded DNA. A crystal structure of AlkA was refined to 2.0 A resolution. This structure in turn was used to refine an AlkA-hypoxanthine (substrate) complex structure to 2.4 A resolution. The complex structure shows hypoxanthine located in AlkA's active site stacked between residues W218 and Y239. The structural analysis of the AlkA and AlkA-hypoxanthine structures indicate that free hypoxanthine binding in the active site may inhibit glycosylase activity.

Degradation of non-diffusible organic matter in biofilm reactors

Abstract A simple laboratory test has been developed in order to demonstrate qualitatively, that the removal of non-diffusible organics in a biofilm reactor requires hydrolysis by extracellular enzymes in the bulk water of the reactor.

The structural and optical properties of gallium arsenic nanoparticles

Spherical gallium arsenic nanoparticles prepared by thermal evaporation method have been fabricated successfully. The structural and optical properties of GaAs nanoparticles are studied in detail. It is found that while the growth pressure rises from 0.4 to 5 Torr, the average size of GaAs nanoparticles increases from 6 to 12 nm and standard deviation keeps almost the same (∼2 nm) except for 0.5 Torr. By using transmission electron microscopy and Raman spectra, a critical preparation condition has been found which characterize the amorphous to crystal transition of GaAs nanoparticles.

Bidirectionality of water-leaving radiance: simulation results and its correction

The bidirectionality of water light field is one of the error sources of the ocean color models that now commonly used to retrieve pigments' concentrations. As the launching of new generation ocean color sensors, e.g. SeaWiFS, or the coming MODIS, the goal of accuracy of ocean color sensing is now much higher than that of CZCS. The original minor factors, such as the bidirectionality of water-leaving radiance, become more important for retrieving algorithms. This paper is to give some results based on 3D Monte Carlo simulations and proposes some aspects that should be considered for in situ optical data collection and related remote sensor's calibration and validation activities.

Risk-Sensitive Policies for Sustainable Renewable Resource Allocation

Markov Decision Processes arise as a natural model for many renewable resources allocation problems. In many such problems, high stakes decisions with potentially catastrophic outcomes (such as the collapse of an entire ecosystem) need to be taken by carefully balancing social, economic, and ecologic goals. We introduce a broad class of such MDP models with a risk averse attitude of the decision maker, in order to obtain policies that are more balanced with respect to the welfare of future generations. We prove that they admit a closed form solution that can be efficiently computed. ::: ::: We show an application of the proposed framework to the Pacific Halibut marine fishery, obtaining new and more cautious policies. Our results strengthen findings of related policies from the literature by providing new evidence that a policy based on periodic closures of the fishery should be employed, in place of the one traditionally used that harvests a constant proportion of the stock every year.

Outcome in unipolar affective disorder after stereotactic tractotomy

An evaluation of 15 patients treated by subcaudate stereotactic tractotomy (SST) for treatment-resistant unipolar affective disorder was made for frequency and severity of recurrence of illness. One-third had died by the time of assessment, but none by suicide. Two-thirds of the sample experienced a reduction in the severity of depressive episodes after the operation; only one-third reported a reduction in frequency of episodes.

Summer diet of seabirds from the Frans Josef Land archipelago, Russian Arctic

Food samples from 102 seabirds from eight species (fulmar Fulmarus glacialis, common eider Somateria mollissima, glaucous gull Larus hyperboreus, kittiwake Rissa tridaayla, arctic tern Sterna paradisaea, Briinnich's guillemot Uria lorn via, black guillemot Cepphus grylle, little auk Alle alle) were collected during the period August 1991–1993 in the southern part of the Frans Josef Land archipelago, 80°N, 53°E. The pelagic amphipod Parathemisto libellula and polar cod Boreogadus saida were the two most commonly taken food items (frequency of occurrence over 50% and weight contribution more than 70%). Ice-associated crustaceans contributed to some 10% of the weight in the samples. In general, the food composition was very similar to that reported from Svalbard. However, birds from Frans Josef Land fed on a lower diversity of prey compared to Svalbard populations.

Factors affecting the times till death of pedestrians killed in road accidents.

Police reports of fatal pedestrian road accidents in London in 1970-71 have been examined, and the times of death extracted. These have been related to estimated speed of impact, age of injured person and type of striking vehicle. High-impact speed tends to lead to quick death. Age has no statistically significant effect once speed is allowed for, but because a greater proportion of elderly pedestrians are killed by slowly moving vehicles, the elderly on average die later than the young when all speed groups are combined. Type of vehicle also influences time of death, with motor cycles giving rise to later deaths and heavy goods vehicles to quicker ones than do cars.

Research on Layered Cooperating Intrusion Detection System

With the fast development of network, hackers develop the abilities to attack remote hosts in different places and times through Internet and they have successfully attack many networks by distributed attacks. In this paper we present the framework and implementation of a layered Cooperating Intrusion Detection System (IDS) based on agent. The main focus in layered cooperating IDS is to overcome the design shortcomings of most currently available host based IDS and network based IDS. This paper explores the use of the formal approach in the Common Intrusion Detection Framework (CIDF), and describes Layered Cooperating Intrusion Detection System (LIDS) based on the extension to the common intrusion specification language (CISL).

Temporal coherence of a Brillouin fiber laser

The linewidth narrowing observed in Brillouin lasers is studied within the framework of the usual three-wave model of stimulated Brillouin scattering. We derive a simple analytical relation connecting the linewidth of the pump laser to that of the Brillouin laser. An experiment is then performed to verify the theoretical prediction.

Copper- and Cobalt-Catalyzed Direct Coupling of sp3 α-Carbon of Alcohols with Alkenes and Hydroperoxides

A zerovalent copper- and cobalt-catalyzed direct coupling of the sp3 α-carbon of alcohols with alkenes and hydroperoxides was developed in which the hydroperoxides acted as radical initiator and then coupling partner. 1,3-Enynes and vinylarenes underwent alkylation–peroxidation to give β-peroxy alcohols and β-hydroxyketones correspondingly with excellent functional group tolerance. The resulting β-peroxy alcohols could be further transformed into β-hydroxyynones and propargylic 1,3-diols.

STUDIES ON SEASONAL CHANGES IN THE BIOCHEMICAL CONSTITUENTS OF THE OYSTER CRASSOSTREA CUCULLATA

Biochemical analysis for a year of Crassosirea cucuUata showed that water content varied from 75.06% to 85.47% and had correlation to change in salinity of estuarine water. Glycogen content varied from 21.45% to 45.03%. Glycogen level fell during spawning and later recovered with gametogenesis. Fat content varied between 4.33% and 11.25%. High fat level was observed during May-Septemb& r, prior to spawning. After spawning there was marked fall in the fat level, which subsequently recovered with the commencement of gonad development. Protein content varied between 52.30% and 70.00%, with the higher values observed during the period of spawning

An Experimental Investigation of Laminar Heat Transfer to Cones at Hypersonic Speeds

Abstract : The present study was an experimental investigation of the laminar surface heat transfer distribution about cones. The study was conducted in the Princeton University hypersonic nitrogen facility and covered a wide range of geometries and test conditions in an attempt to evaluate the numerical accuracy, theoretical modeling, and range of applicability of the several theories which are available. Cones, varying from 3 degrees to 30 degrees, with two nose bluntnesses, and lengths from one to eight inches were examined over a range of test conditions: Mach numbers from 16 to 25, and unit Reynolds numbers from 7,000 to 40,000 per inch. The detailed heat transfer distributions, covering the full range of 'nose dominated', 'merged', and 'weak interaction' regimes, were compared with several theoretical prediction techniques. A critical review of the modeling involved in the theories, as compared to the experiments, is presented. (Author)

On the Desire Discourses of Literature in the 1990s and the Happiness Philosophy of Taoism

With the establishment of socialist market economy system and the rise of consumerism,the desire discourses of Literature in the 1990s prevail.Among them,material desire and sexual desire are more extensive and typical,the former appear as aspiring of material luxury,and the latter as pursuing of sense gratification mainly about the instinct for sex.As we compare the desire discourses of the 1990s Literature with the happiness philosophy of Taoism,we discover that the former and the latter constitute a relatively complex relationship: partially conjunct to the happiness philosophy of Taoist carnalism which is represented by the metaphysics of Wei-Chin Dynasty,and deconstructive to the happiness philosophy of Taoist inaction which is represented by the Lao Zhuang philosophy,these complicated relationships manifest the profound changes of the living style and spiritual world in our time.

Two-way shape memory effect in polymer laminates

Novel polymer laminate exhibiting two-way shape memory effect has been prepared by layer technique with the shape memory polymer and elastic polymer. In this paper, we demonstrate the two-way shape memory behavior, i.e., bending on heating and reverse bending on cooling; describe the preparation procedure; and investigate its two-way shape memory mechanism. Finally, it suggests that the mechanism can be ascribed to the release of elastic strain of shape memory polymer layer upon heating, and the elastic strain recovery induced by the bending force of substrate layer upon cooling.

Hierarchical Goal Networks and Goal-Driven Autonomy: Going where AI Planning Meets Goal Reasoning

Planning systems are typically told what goals to pursue and cannot modify them. Some methods (e.g., for contingency planning, dynamic replanning) can respond to execution failures, but usually ignore opportunities and do not reason about the goals themselves. Goal-Driven Autonomy (GDA) relaxes some common assumptions of classical planning (e.g., static environments, fixed goals, no unpredictable exogenous events). This paper describes our Hierarchical Goal Network formalism and algorithms that we have been working on for some time now and discusses how this particular planning formalism relates to GDA and may help address some of GDA’s challenges.

Free Care: A Quantitative Analysis of Health and Cost Effects of a National Health Program for the United States

We estimate the health and cost effects of instituting a National Health Program (NHP) in the United States that would provide universal, comprehensive free care. Based on empiric studies of the relationship of health service use to cost and health outcomes, we estimate that an NHP would increase use of health services by 14.6 percent and save between 47,000 and 106,000 lives annually. Because the United States faces a growing surplus of hospital beds and physicians, additional services could be provided at low cost. Simplifying the health bureaucracy that currently enforces unequal access to care would also result in substantial savings. Consequently, an NHP would actually decrease costs 2.4 percent, $10.2 billion annually, since the $35.7 billion spent for additional services would be offset by $45.9 billion saved on bureaucracy.

Advanced PM brushless DC motor control and system for electric vehicles

Electric vehicles may be one of the main future transportation trends from the next decade due to their low-pollution and high efficiency. Reviewing the papers in the literature we can see that the best motive equipment is permanent magnet brushless DC (PM BLDC) motor. Many papers discuss the power supply for PM BLDC motors. This paper introduces a novel digital signal processor (DSP) controlled pulse width modulated (PWM) chopper to drive a PM BLDC motor. The main power supply unit is a chopper consisting of three power switches, which has a simple circuit and low-cost topology with less power losses. A comprehensive analysis on the principle of operation, design considerations and control algorithms implemented are described in this paper. The analysis also includes simulation and experimental results based on the prototype developed. The main objective is to achieve cost minimization and a simple structure drive system that is suitable for electric vehicle applications.

Sources and Levels of Stress in Relation to Locus of Control and Self Esteem in University Students

This study reports an investigation into the sources and levels of stress in relation to locus of control and self esteem in university students. Two stress questionnaires (ASQ and LSQ) were used to assess students’ stress. The first deals with academic sources of stress, and the second assesses the student's life stress levels. The achievement scale of the Multidimensional Multi‐attributional Scale Causality (MMCS) was used to measure locus of control, and the Rosenberg Self Esteem Scale to assess students’ self esteem. The study sample consisted of 675 (202 males and 473 females) second‐year undergraduate students. The results indicated that examination and examination results were the highest causes of stress in students, followed by studying for exams, too much to do and the amount to learn, respectively. Results showed that 77.6% and 10.4% of the students fall into the moderate and serious stress categories, respectively, and that there were significant differences between females and males students ...

Double dependent market economy and corporate social responsibility in Hungary

In the different varieties of capitalism (VoC) different types of corporate social responsibility (CSR) exist (Matten and Moon 2008). In order to identify what CSR is like in Hungary all the five institutions that are relevant for the variety of capitalism in this country are analyzed and a new concept is introduced named double-dependent market economy (DDME) by the author. This concept allows the further exploration of the general type of CSR in Hungary and answers the question whether it is similar to that of the European coordinated economies or of the liberal Anglo-Saxon market economies, or it is something completely different. The results of the quantitative and qualitative research show that CSR in Hungary has some patterns of the CSR types of both the liberal and coordinated economies but on the whole it is fundamentally different from those due to the dissimilar institutional setting of capitalism in this country.
