Thalidomide and Congenital Abnormalities | The continued interest by medical observers and the preoccupation of the daily press with the effects of thalidomide on the foetus encourages yet another account of congenital abnormalities believed to be due to thalidomide ("distaval") taken during pregnancy. Although the account which follows dates from February, I %2. publication was delayed because all the medical literature at that time suggested a direct relation between the time in pregnancy at which thalidomide was taken and the type of malformation produced, implying that arrest of development occurs in organs actively forming in the weeks when the drug is being taken. In this case the mother had taken thalidomide for |

Gateshead library is developing compact disc interactive (CD-I) as a medium for publishing information for disabled people which includes information in British Sign Language. > |
Jean Baptiste Apuatimi, jilamara, and art history on the Tiwi Islands | Abstract Ethnography is the principal method for studying the art of the Tiwi Islands, as it is for the study of Aboriginal Australian art more generally. Relying on the testimonies of the artists themselves, scholars use Tiwi art to build knowledge of Tiwi cosmologies and society. This essay turns to the oeuvre of Tiwi artist Jean Baptiste Apuatimi to argue that the methodology of visual analysis can also contribute to knowledge of Tiwi cosmology and society. The persistence of the jilamara design in her oeuvre can be related to the global phenomenon of geometric design. For the art historian Wilhelm Worringer, the emergence of geometric ornament in different societies betrays anxieties about the cosmological place of a people in the world. Tiwi jilamara can be read in terms of such anxiety in a contribution to the scholarship on Tiwi society that relies on the evidence of art practice rather than ethnography. |

Construction and Validation of Educational Tests | RESEARCH in the field of test construction and validation was reviewed most recently by Schrader and Conrad in the December 1948 issue of the REVIEW. The February 1947 issue included a chapter by Travers which dealt with item and test characteristics, reliability, validity, and factor analysis, among other matters. Meder and Eagle reviewed measurement in mathematics and science in the October 1948 issue. |
Obstruction Set Isolation for the Gate Matrix Layout Problem | Abstract Gate matrix layout is a well-known NP -complete problem that arises at the heart of a number of VLSI layout styles. Despite its apparent general intractability, it has recently been shown that it can be solved in O(n2) time whenever the number of tracks is fixed. Curiously, the proof of this is nonconstructive, based on finite but unknown obstruction sets. What then are such sets, and what is their underlying structure? The main result we report in this paper is a proof that the obstruction set for three tracks contains exactly 110 elements. We also describe a number of methods for obstruction identification that extend to any number of tracks. |

On analysis of Petri net properties based on transitive matrix | Petri nets (PNs) are a useful graphical and mathematical tool to model and analyze discrete event systems. In this paper, the authors provide a new concept to analyze PN properties based on graph theory. First, they show the method to convert PNs into directed graphs, and then introduce the transitive matrices of PNs. Second, structural properties are examined using the characteristic polynomial and equation of the transitive matrices, and applying the Mason's theorem derived from signal-flow-graphs. Furthermore, behavioral properties concerning the transition firing orders are discussed using the power of the transitive matrices. |

Protein classification based on optimization of discriminant model | Classifiers based on discriminant model achieved the highest accuracy compared to other protein classification methods in remote homology detection,but all of the classifiers were troubled by imbalance training in modeling. This paper presented a protein classification based on optimization of discriminant model to further improve the classifier performance by setting different penalty coefficients for the positive and negative samples to balance the training set weights. Comparative experiments show that the method based on optimized discriminant model obtained higher accuracy,and the method can improve the performance of all classifiers based on discriminant model by optimization of the parameters. |

A low-noise differential microphone inspired by the ears of the parasitoid flyOrmia ochracea | A miniature differential microphone is described having a low-noise floor. The sensitivity of a differential microphone suffers as the distance between the two pressure sensing locations decreases, resulting in an increase in the input sound pressure-referred noise floor. In the microphone described here, both the diaphragm thermal noise and the electronic noise are minimized by a combination of novel diaphragm design and the use of low-noise optical sensing that has been integrated into the microphone package. The differential microphone diaphragm measures 1 x 2 mm(2) and is fabricated out of polycrystalline silicon. The diaphragm design is based on the coupled directionally sensitive ears of the fly Ormia ochracea. The sound pressure input-referred noise floor of this miniature differential microphone has been measured to be less than 36 dBA. |

Maternal-fetal transfer and metabolism of vitamin A and its precursor β-carotene in the developing tissues. | The requirement of the developing mammalian embryo for retinoic acid is well established. Retinoic acid, the active form of vitamin A, can be generated from retinol and retinyl ester obtained from food of animal origin, and from carotenoids, mainly β-carotene, from vegetables and fruits. The mammalian embryo relies on retinol, retinyl ester and β-carotene circulating in the maternal bloodstream for its supply of vitamin A. The maternal-fetal transfer of retinoids and carotenoids, as well as the metabolism of these compounds in the developing tissues are still poorly understood. The existing knowledge in this field has been summarized in this review in reference to our basic understanding of the transport and metabolism of retinoids and carotenoids in adult tissues. The need for future research on the metabolism of these essential lipophilic nutrients during development is highlighted. This article is part of a Special Issue entitled: Retinoid and Lipid Metabolism. |

A dead-beat current controller based wind turbine emulator | The paper presents the development of a wind turbine emulator, which consists of an induction motor driven by a torque control inverter, and the dead-beat controller plays an important role in this structure. The wind turbine emulator system includes the dead-beat current controller, wind speed emulator, mathematical model of wind turbines, model of rotor blade characteristics, and model of tower effect and rotor inertia. The advantages of the emulator are various wind profiles and wind turbines can be simulated as desired in the control software and it is also integrated the data acquisition to verify the control algorithms and display the parameters. The experimental results confirmed the wind turbine simulator could perform satisfactory under steady state wind profile. This approach provides an instantaneous torque output, which is particularly advantageous for the proposed controller. |
Surface chemistry of polyethylene grafted with hydrophilic monomers: XPS and ToF-SIMS studies | Polyethylene (PE) powders were grafted by acrylic acid or maleic anhydride/styrene monomers. The elemental surface composition was determined by means of X-ray photoelectron spectroscopy (XPS). Time-of-flight secondary ion mass spectrometry (TOF-SIMS) investigations were carried out to obtain information about the molecular build-up of the grafted polymers. XPS measurements showed the presence of oxygen-containing functional groups on the PE particle surface. The TOF-SIMS spectra gave evidence for polymer chains with alternating maleic anhydride and styrene units. In addition, fragments of polystyrene block segments were found. |

Security test generation using threat trees | Software security issues have been a major concern to the cyberspace community, so a great deal of research on security testing has been performed, and various security testing techniques have been developed. Most of these techniques, however, have focused on testing software systems after their implementation is completed. To build secure and dependable software systems in a cost-effective way, however, it is necessary to put more effort upfront during the software development life cycle. In this paper, we provided a security testing approach that derives test cases from design-level artifacts. The security testing approach we consider consists of four activities: building threat trees from threat modeling; generating security tests from threat trees; generating test inputs including valid and invalid inputs; and assigning input values to parameters. We also conducted an empirical study to show feasibility of our approach. |

Markov chain approximations to, and some fluctuation results for, Lévy processes | We introduce, and analyze in terms of convergence rates of transition kernels, a continuous-time Markov chain approximation to Levy processes. A full fluctuation theory for what are right-continuous random walks embedded into continuous-time as compound Poisson processes, is provided. These results are applied to obtaining a general algorithm for the calculation of the scale functions of a spectrally negative Levy process. In a related result, the class of Levy processes having non-random overshoots is precisely characterized. |
Monetary Policy and Global Equilibria in an Economy with Capital | Short-term interest rates in the United States have been near their lower bound since late 2008. Treasury rates out to a two-year maturity have been close to zero since mid-2011, and over this same period, inflation has been declining. This combination of low interest rates and declining inflation has lead some observers to point to the "perils of Taylor rules," for example, Bullard (2010), when a monetary policy that actively targets a positive inflation rate leads to an outcome with much lower inflation, and possibly even deflation. The possibility of equilibria with persistent deviations of inflation from the target set by the policy maker has been investigated for model economies without state variables. Quantitative representations of the U.S. economy as embodied by DSGE models include as an essential element capital accumulation. In this paper we study the possibility for persistent low inflation outcomes for a monetary model with capital. |

Modeling Data Lake Metadata with a Data Vault | With the rise of big data, business intelligence had to find solutions for managing even greater data volumes and variety than in data warehouses, which proved ill-adapted. Data lakes answer these needs from a storage point of view, but require managing adequate metadata to guarantee an efficient access to data. Starting from a multidimensional metadata model designed for an industrial heritage data lake presenting a lack of schema evolutivity, we propose in this paper to use ensemble modeling, and more precisely a data vault, to address this issue. To illustrate the feasibility of this approach, we instantiate our metadata conceptual model into relational and document-oriented logical and physical models, respectively. We also compare the physical models in terms of metadata storage and query response time. |

Assembly Line Control Models in Automotive Industry | Publisher Summary This chapter discusses assembly line model within the framework a production control and information computer system consisting of five basic functional areas. It describes the production control area where the problem of finding an optimum sequence of different vehicle types and options that are to be completed assembly line was solved. The relevant mathematical model is based on the daily vehicle schedule and considers assembly timing data of different vehicle types, loading of each work center and technological restrictions. The control of movements of selected parts and conveyor control are integral parts of the algorithm. The total system problem area was divided according the nature of various production, planning and control activities into the following main functional areas: (1) production planning, (2) production scheduling, (3) production monitoring and reporting, (4) production control, (5) quality control. |
Coastal polynyas in the southwestern Weddell Sea: sea ice production and bottom water formation | Coastal polynyas are areas in the ice-covered ocean from which the sea-ice cover has been mechanically removed, primarily by winds. They are areas of enhanced exchange processes between ocean and atmosphere. The increased heat flux allows for exceptionally high freezing rates, which lead to locally increased brine-rejection. In the southwestern Weddell Sea, wide continental shelves and a weak exchange with the open ocean provide conditions that allow for substantial salinity enrichment, forming the cold and saline High Salinity Shelf Water (HSSW), which is the densest water mass in the region. HSSW is one of the ingredients of Weddell Sea Bottom Water (WSBW) and is thus essential for the formation of Antarctic Bottom Water, which covers large parts of the World Ocean’s abyss. Thus, production rates of HSSW and WSBW are of crucial importance in the ocean’s global thermohaline circulation. |
A novel strategy by the action of ricin that connects phenotype and genotype without loss of the diversity of libraries. | We present a novel strategy for connection of phenotype and genotype in vitro that can be used for the selection of functional proteins even at room temperature. The strategy involves generation of a stable complex between a ribosome, an mRNA, and its translated protein, without removal of the termination codon, as a result of the action of the ricin A chain during translation. We demonstrate the potential selection capacity of this novel strategy by isolating such complexes that contain newly synthesized streptavidin and glutathione-S-transferase (GST) using appropriate ligands. The technique requires no transfection, no chemical synthesis, no ligation, and no removal of the termination codon. Thus our novel "Ribosome-Inactivation Display System (RIDS)" should provide, without loss of the pool population, a reliable, simple, and robust selection system for in vitro evolution of the properties of proteins in a predictable direction by a combination of randomization and appropriate selection strategies. |
Positive numerical splitting method for the Hull and White 2D Black–Scholes equation | We consider the locally one-dimensional backward Euler splitting method to solve numerically the Hull and White problem for pricing European options with stochastic volatility in the presence of a mixed derivative term. We prove the first-order convergence of the time-splitting. The parabolic equation degenerates on the boundary x = 0 and we apply a fitted finite volume scheme to the equation to resolve the degeneracy and derive the fully discrete problem as we also investigate the discrete maximum principle. Numerical experiments illustrate the efficiency of our difference scheme. © 2014 Wiley Periodicals, Inc. Numer Methods Partial Differential Eq 31: 822–846, 2015 |
Antinociceptive and behavioral effects of leu-enkephalin (LENK) or D-Ala2-met-enkephalinamide (DAMEA) in rats after central chemical sympathectomy or serotoninectomy. | In rats with central chemical sympathectomy induced by two injections into the lateral brain ventricle (icv) of 250 micrograms of 6-hydroxydopamine or with central chemical serotoninectomy induced by 75 micrograms of 5,6-dihydroxytryptamine icv the antinociceptive and behavioral effects of LENK (200 micrograms icv) or DAMEA (10 or 20 micrograms icv) were examined. The chemical lesion of central noradrenaline or dopamine neurons or specific lesion of serotonin neurons abolished antinociceptive effects of LENK and DAMEA. Both peptides inhibited exploratory activity of rats. Central chemical serotoninectomy but not sympathectomy reversed some behavioral effects induced by LENK and DAMEA. These results suggest modulatory influence of the central noradrenaline and serotonin neurons in the antinociceptive mechanism of action of enkephalins and the participation of the central serotonin neurons on the behavior of rats induced by enkephalins. |
Identification of astaxanthin diglucoside diesters from snow alga Chlamydomonas nivalis by liquid chromatography-atmospheric pressure chemical ionization mass spectrometry. | Abstract A method is described for the identification of astaxanthin glucoside esters from snow alga Chlamydomonas nivalis by means of liquid chromatography–mass spectrometry with atmospheric pressure chemical ionization (LC–MS/APCI). The method is based on the use of preparative HPLC and subsequent identification of astaxanthin diglucoside diesters by microbore LC–MS/APCI. The combination of these two techniques was used to identify more than 100 molecular species. The astaxanthin diglucoside diester, i.e. (all-E)-[di-(6-O-oleoyl-β- d -glucopyranosyloxy)]-astaxanthin, was also synthesized to unambiguously confirm its structure. |
Estimation of Critical Flow Velocity for Collapse of Gas Test Loop Booster Fuel Assembly | This paper presents calculations performed to determine the critical flow velocity for plate collapse due to static instability for the Gas Test Loop booster fuel assembly. Long, slender plates arranged in a parallel configuration can experience static divergence and collapse at sufficiently high coolant flow rates. Such collapse was exhibited by the Oak Ridge High Flux Reactor in the 1940s and the Engineering Test Reactor at the Idaho National Laboratory in the 1950s. Theoretical formulas outlined by Miller, based upon wide-beam theory and Bernoulli’s equation, were used for the analysis. Calculations based upon Miller’s theory show that the actual coolant flow velocity is only 6% of the predicted critical flow velocity. Since there is a considerable margin between the theoretically predicted plate collapse velocity and the design velocity, the phenomena of plate collapse due to static instability is unlikely. |
Impact Of Advances In Technology On The Properties Of Si/SiO2 Interface | With the continuing progress in the Si-VLSI technology from one generation to the next, the number of ion-implantation and dry-etching processes which cause damages to the Si/SiO2 interface region has increased, while at the same time the oxidation and annealing temperatures have decreased, The net impact is manifested as a significant monotonic decrease in the low-field mobility of the inversion layer electrons. Furthermore, the response of the interface to the CO60 source of gamma rays, and the effects of radiation damage on the rate of drift in MOSFETs due to injection of hot-carriers, suggest that the advances in technology have increased the susceptibility of IC's to hot-carrier injection related drifts. |
An explanation-based tools for debugging constraint satisfaction problems | This paper describes an explanation-based tools for constraint programming system. These tools provide to the user the conflicts when it raise during solving process. Our tools simulate constraint additions and/or constraint relaxations without any propagation; it also determine if a given constraint belongs to a conflict and it provide diagnosis tool (e.g. why variable v cannot take value val?). With more user-friendly representation of conflicts and explanations, our proposed tools give better problem understanding to the user. We prooved that the proposed tools are efficient, and while there is no debugging system that allow the user to interact with the solver, our explanation-based tools could be used for many other applications. |

Estrogen and Thromboembolic Disorders: Should Patients Stop Hormones Prior to Cosmetic Surgery? | Oral contraceptives and replacement estrogenic hormones have been associated with a significant risk of thromboembolism. Cosmetic surgery consists of elective procedures in otherwise healthy individuals. The prospect of thromboembolism should be diminished in these patients by avoiding those factors that may give rise to the problem. Stopping oral contraceptives and replacement estrogens three weeks before surgery to two weeks after surgery is not difficult for most patients and should be part of the custom and practice of all cosmetic surgeons. |

Thermal/Photo Conversion of Silver 4-Nitrobenzoate to Nitro/Amine-Terminated Silver Nanoparticles | We have investigated the thermal and photochemical characteristics of silver 4-nitrobenzoate (Ag-4NBA) using various analytical tools, such as, X-ray diffraction (XRD), diffuse reflectance infrared Fourier transform spectroscopy, Raman spectroscopy, thermogravimetric analysis, scanning electron microscopy, and transmission electron microscopy. The XRD pattern was composed of a series of peaks that could be indexed to (0k0) reflections of a layered structure. Upon heating the sample, structural changes took place particularly at two specific temperatures. The binding state of the carboxylate group changed from bridging to unidentate at ∼380 K. A second dramatic structural change occurred at ∼590 K, producing 4NBA-capped Ag nanoparticles. The latter transition temperature for Ag-4NBA is about 80 K higher than that for silver alkanecarboxylates, and such enhanced thermal stability of Ag-4NBA must be associated with the conjugation of the carboxylate group to the aromatic ring. On the other hand, Ag-4NBA was ... |
[Detection of hyperamylasuria. Value of a quick test]. | A new reactive strip was used in a hospital admission unit, to detect amylasuria in the urine of 76 patients consulting for abdominal pain (population A) and of 68 unselected patients (population B). Detection on admission by this method was concordant with subsequent laboratory detection in 93% of the cases. The fast test was positive for amylasuria in 17 patients: 13 (17.1%) in population A and 4 (5.9%) in population B. The 8 patients recorded as "+" had moderate amylasuria with multiple but ill-defined symptoms mostly abdominal. The 9 patients recorded as "++" had marked amylasuria highly suggestive of an abdominal disease, including 4 cases of chronic pancreatitis. |

Twenty new microsatellite loci for population structure and parentage studies of Parnassius apollo nevadensis (Lepidoptera; Papilionidae) | We characterized 20 new microsatellite loci isolated from Parnassius apollo nevadensis. The 20 loci displayed 2–12 alleles and expected heterozygosities varied from 0.22 to 0.89; the markers were amplified in nine multiplex reactions. The combined non-exclusion probabilities of this set are 0.001084 and 0.000005 for the first and second parents, respectively. This set of markers will thus enable other studies on reproductive strategies and population genetics in this endangered and previously understudied species. We show, for the first time, evidence of multiple paternity and that females may successfully copulate with more than one male despite the presence of mating plugs. Future studies on this mating behavior and population genetics of the species using the 20 loci here presented will be very important to define its conservation status and management measures. |
Correlated magnetism in low-doped manganites | Abstract In this article, resonant and high-energy X-ray diffraction studies together with magnetization and transport measurements on lightly doped manganites will be presented. The main focus is put on the metal–insulator transition in La 1 - x Sr x MnO 3 with 0.10 x 0.15 and, in particular, on the stabilization of the ferromagnetic insulating (FMI) phase of these compounds. The experimental results reveal an orbital rearrangement at the metal–insulator transition which is tightly connected to the magnetic degrees of freedom. More precisely, the double exchange mechanism is found to be essential for the stabilization of the FMI phase. This conclusion is further supported by the studies on ( La 1 - y Pr y ) 7 / 8 Sr 1 / 8 MnO 3 and the layered compound La 7 / 8 Sr 9 / 8 MnO 4 . |
3. Uses of Evidence in Disability Outcomes and Effectiveness Research | Outcomes and effectiveness research is a category of health services research that gauges how well the health care needs of persons with disabilities are being met. Using Patrick's Model of Health Promotion for people with disabilities as a framework for analysis, this article examines outcomes and effectiveness research related to the health care needs of persons with disabilities. The three most pressing research priorities are clear theoretical conceptualizations and qualitative research on health outcomes relevant to the needs of persons with disabilities; a systemic analysis of existing assessment instruments' utility for disability outcomes research; and the development and testing of new outcome instruments. |
Developing an Effective Emergency Management Partnership: Surf Life Saving Australia and Ambulance Services | Surf Lifesavers are an important link in the Australian emergency management and patient care system. In addition to more than 11,000 rescues performed nationally each year, the organisation provides in excess of 35,000 first aid and emergency care treatments. Recognising that collaboration with ambulance services is a critical element in the chain of emergency care, Surf Life Saving Australia is actively developing improved partnerships with ambulance services and their paramedics. This paper describes policies and procedures currently in place, provides a snapshot of beach incidents involving lifesavers and paramedics, and reports on a survey of ambulance officers in Queensland exploring their views and experiences working with lifesavers. Results provide a template for other water safety groups to work more effectively with government emergency services. |
El Quinto Suyo Contemporary Nation Building and the Political Economy of Emigration in Peru | Since the 1980s, political instability and national and global economic crisis have increasingly undermined the ability of the Peruvian state to maintain a viable national economy and sustain its population. The past decade has seen efforts by the state to reclaim emigrant citizens and facilitate their incorporation into a redefined Peruvian nation that extends beyond the country’s borders. Examination of two instances of the struggle over extraterritorial membership and the processes of inclusion and exclusion emerging from this struggle suggests that by extending both symbolic and material membership to the emigrant population the Peruvian state is restructuring and reconceptualizing itself in the context of a changing global economy. |
THE USE OF DICHLOROMETHANE IN THE RECOVERY OF BITUMEN FROM ROAD MATERIALS | CARBON DISULPHIDE, WHICH IS THE SOLVENT SPECIFIED FOR USE IN THE STANDARD METHODS OF RECOVERING BITUMENS FROM ROAD MATERIALS, IS HIGHLY FLAMMABLE AND EXTREMELY TOXIC. THIS REPORT GIVES THE RESULTS OF EXPERIMENTS CARRIED OUT TO DETERMINE WHETHER DICHLOROMETHANE, WHICH IS NON-FLAMMABLE AND OF LOW TOXICITY, COULD BE USED INSTEAD. THESE RESULTS SHOW THAT THE SUBSTITUTION CAUSES NO MARKED CHANGE IN THE VISCOSITY OF PENETRATION-GRADE BITUMENS SUBJECTED TO THE RECOVERY PROCESS. DICHLOROMETHANE CANNOT AT PRESENT BE RECOMMENDED FOR THE RECOVERY OF CUT-BACK BITUMENS AND THE PROBLEM OF RECOVERY OF SUCH BINDERS WITH ANY SOLVENT REQUIRES FURTHER INVESTIGATION. /AUTHOR/ |
Revisiting 'Dreyfus': A More Complete Account of a Trial by Mathematics | Legal literature and case law depicts the infamous conviction of Alfred Dreyfus for treason and espionage in 1899 as a prime example of the irresistible power of even grossly fallacious mathematical demonstrations to overwhelm a legal tribunal. This essay shows that Dreyfus is not a case of mathematics run amok, unchecked and uncomprehended. To the contrary, the defects in the mathematical proof were dramatically exposed, and this evidence did not lead Dreyfus's judges to condemn him. This history undercuts the reliance of modern courts and commentators on Dreyfus as an indication or illustration of the alleged dangers of probability evidence in criminal cases. |
What to Tell a Graduate Course in Macroeconomics about Keynes | Abstract ::: Although the global economic crisis that began in 2007 has renewed interest in Keynes among the wider educated public, graduate courses in macroeconomics usually teach little about Keynes and the issues he analyzed, and what little they teach is often wrong (e.g., that Keynes assumed an arbitrarily fixed money wage rate or that he ignored expectations). Consequently, as macroeconomists turn their attention to the possibility, causes and consequences of financial crises and global depression, they do not have access to the insights into these questions produced by earlier generations of economists. The time and attention constraints of theory courses do not allow simply directing the students to the extensive scholarly literature on the economics of Keynes, so this paper offers a suggested introduction to the economics of Keynes for a graduate course in macroeconomics. |
Vinyl acetate catalyst and preparation method | The invention relates to a vinyl acetate catalyst and a preparation method thereof which are mainly used for solving the problems of space time yield and low selectivity of the prior art.

High-power gas dynamically cooled CO laser with unstable resonator | The RF-discharge region of a gasdynamically cooled carbon monoxide laser has been optimized. Thereby the laser power was increased from 2.5 kW to a value of 7 kW (stable resonator) with an efficiency of 14%. An unstable resonator has been applied to improve the beam quality resulting in a 4.7 kW laser beam with a total divergence of 2.5 mrad. The beam quality is strongly influenced by water vapor absorption in the beam delivery system. The design of the RF-excited laser will be described and experimental results will be presented. |
Clinical Predictors of Critical Lower Respiratory Tract Illness Due to Respiratory Syncytial Virus in Infants and Children: Data to Inform Case Definitions for Efficacy Trials. | We analyzed data from 524 Argentinean infants hospitalized with lower respiratory tract illness (LRTI) due to respiratory syncytial virus (RSV) to inform selection of clinical end points for RSV vaccine efficacy trials. Cases of LRTI due to RSV that required a mask, continuous or bilevel positive airway pressure, or mechanical ventilation were classified as critical. Oxygen saturation of ≤90%, tachypnea, and tachycardia were each associated with an increased odds of critical LRTI due to RSV (adjusted odds ratios [ORs], 2.30 [95% confidence interval {CI}, 1.26-4.24; P = .007], 2.22 [95% CI, 1.19-4.16; P = .012], and 2.35 [95% CI, 1.22-4.50; P = .010], respectively). The odds of critical LRTI due to RSV increased substantially (OR, 8.57; 95% CI, 2.19-73.5; P = .001) among individuals with ≥2 indicators. Lower chest wall indrawing was not associated with critical disease. |
The determination of fault movement history from the interaction of local drainage with volcanic episodes | The Kula volcanic province lies in an area of active normal faulting in western Turkey. In this study, we show that the interaction of the basalts with the local drainage, and in particular the Gediz river, can be used to determine the history of fault movements downstream. The lava flows have been studied previously, and some of them dated. We use these results and combine them with new field observations of lavas that flowed into the river valley to measure the rate of down-cutting of the river and hence the rate of uplift of the footwall block due to movement of the graben-bounding fault. We show that there has been, in general, an acceleration of fault movement with time during the last 2 Ma. This increased activity of the graben-bounding fault is matched by an intensification of volcanic activity. An inferred four-fold increase in fault movement rate over the last 0.2 Ma has been matched by a similar increase in volume of volcanic activity. |
Specific monoclonal antibodies to Fasciola gigantica. | Monoclonal antibodies (mAbs) were produced against soluble metabolic products (excretory/secretory; ES) of the liver fluke, Fasciola gigantica. The ES antigen was obtained from spent culture medium in which the adult flukes had been maintained in vitro. From two cell fusions, the mAbs produces were exclusively associated with either IgG or IgM isotypes. When screened against a panel of homologous and heterologous parasite antigens by indirect ELISA, two mAbs were highly specific for F. gigantica. The remainder cross-reacted extensively with other parasites. Results from immunoblotting and immunofluorescence exhibited two patterns of reactivity. The first group of mAbs which recognized the multiple bands between > 14.4-27.5 kDa gave extremely bright fluorescence over all major muscular systems, vitelline gland, testes and intestinal caeca. The second group which reacted with the 185 kDa band showed a bright fluorescence over a thinner muscular layer underlying the tegument, intestinal caeca and testes. |
The Moon as a solar power satellite | This paper discusses a modified version of the Satellite Solar Power System, (SPS), originally proposed in 1968 by Dr. Peter Glaser of MIT, as a series of large, photovoltaic solar collector satellites orbiting at geosynchronous (22,500 mile) altitude. The solar energy collected would be beamed to the earth surface 24 hours a day, using microwave energy (which can pass through cloud cover). This system was studied extensively by several large aerospace companies under the joint sponsorship of the D.O.E and NASA between 1977 and |
STUDY ON THE CLOSED DYNAMICS MODEL OF OPERATING ROBOT WITH THE INTACT MOTION CONSTRAINT | An Euler Lagrange equation of the multi rigid body system,expressed by generalized coordinates and constrained with intact motion,was established.The recurrence algorithm of orthogonal complement matrix was discussed when the equation was applied to opperating robot. |
An optical machine for measuring sphere coordinates in random packings | A simple optical machine for measuring and automatically recording quickly and accurately the coordinates of steel spheres in any array is described. Results over very large (similar 8000) assemblies of ¼ in spheres show an improved accuracy of measurement over previous instruments, the standard deviation of the error curve being reduced by over a factor of 2, or 5 when the increased capacity of the machine is taken into account. The machine may be used for a variety of systems, including multicomponent mixtures. |

Biodegradation of low-density polyethylene by Microbulbifer hydrolyticus IRE-31 | Polyethylene (PE) is one of the most widespread plastic materials. Nevertheless, due to its recalcitrance against biological degradation and the presence of toxic additives, landfilled and carelessly disposed PE products have caused serious pollution in the natural environments. In this work, we aimed to investigate the growth characteristics of Microbulbifer hydrolyticus IRE-31 and its application in the biological degradation of low-density PE. The IRE-31 strain was isolated from marine pulp mill wastes rich in lignin which is a natural complex polymer containing also saturated carbon-carbon bonds like in PE. Following 30 days cultivation of the IRE-31 strain, the biodegradation of linear low-density PE particles was evidenced clearly by morphological changes of the polymer surface monitored by scanning electron microscopy and the formation of additional carbonyl groups in the polymer chains indicated by Fourier transform infrared spectroscopy. |
Calorimetry, densitometry and ultrasonics: recent contributions to the thermodynamics of fluids | This article reviews recent advances in the thermodynamics of fluid nonelectrolytes, pure and mixed. The focus is on high-precision experimental techniques and the following topics are included : vapor-liquid equilibrium studies on dilute solutions, calorimetric techniques for measuring heats of mixing and/or solution as well as heat capacities, densitometry at elevated temperatures and pressures, and speed of sound measurements. Some of the problems encountered in data reduction and data correlation will also be indicated. |
Scalable Clustering Using Graphics Processors | We present new algorithms for scalable clustering using graphics processors. Our basic approach is based on k-means. By changing the order of determining object labels, and exploiting the high computational power and pipeline of graphics processing units (GPUs) for distance computing and comparison, we speed up the k-means algorithm substantially. We introduce two strategies for retrieving data from the GPU, taking into account the low bandwidth from the GPU back to the main memory. We also extend our GPU-based approach to data stream clustering. We implement our algorithms in a PC with a Pentium IV 3.4G CPU and a NVIDIA GeForce 6800 GT graphics card. Our comprehensive performance study shows that the common GPU in desktop computers could be an efficient co-processor of CPU in traditional and data stream clustering. |
Influence of lipid concentration on the hydrolysis and biomethanation of lipid rich wastes | The influence of lipid concentration on hydrolysis and biomethanation of an artificial lipid rich (triolein) waste was evaluated. No inhibition on methane production was observed for tests with 5, 10 and 18 % (w/w, based on COD) of lipid. For higher amounts of lipid (31, 40 and 47 %) inhibition was observed. However, the process was able to recover from the inhibition. When the effect of lipase addition on enzymatic hydrolysis of lipids was studied, results showed that the higher the enzyme concentration, the more accentuated was the inhibition of the methane production. The enzyme seems to enhance the hydrolysis and produced intermediates are causing inhibition of the later steps of the degradation process. Since the VFA profiles presented similar trends for the different lipid amounts tested, the major obstacle to methane production is believed to be the LCFA formed. |
The role of plain films, CT, tomography, ultrasound, and percutaneous needle aspiration in the diagnosis of inflammatory lung disease. | Traditionally, plain film chest radiography has been the mainstay in the roentgenographic evaluation of infectious disease in the chest. Plain film tomography has augmented the chest radiograph in the detection of cavitation and in evaluation of the bronchial tree. Newer imaging modalities including ultrasound, which evaluates the pleural space, and computerized tomography (CT), which examines the lung parenchyma, mediastinum, pleura, and chest wall, have further aided in diagnosis. Finally, percutaneous aspiration of the lung or pleural space under radiologic guidance now allows specific diagnoses to be made more frequently and with fewer complications. |
Remarques sur la philosophie religieuse des sectes syncrétiques au Gabon | ABSTRACTTwo sources are at the origin of the religious philosophy of the syncretic sects of Gabon: on the one hand, a religious vision of the world based on traditional religious beliefs, and on the other, occidental Catholicism implanted in Africa. The essentially African foundation of this philosophy lies mainly in the cult of ancestors, the Bouiti, to which cult were then added Christian ideas, adapted and partly transformed. The Bouiti thus could become the corner-stone of the philosophical or even philosophico-religious thought in Gabon. It already contained the elements of a philosophical language which could hence serve to express the traditional religious truths, developing them and adapting them to the socio- cultural and religious needs of the moment.This philosophical language itself took life a long time after, following circumstances favorable to its growth, at a time of economical, political and, therefore, of socio-cultural, changes. It could also be considered as a manifestation of new nee... |
COMPARISON OF TERRESTRIAL LASER SCANNER WITH DIGITAL AERIAL PHOTOGRAMMETRY FOR EXTRACTING RIDGES IN THE RICE PADDIES | Abstract The patches of the rice paddies are generally positioned by a traditional surveying method such as Plane Table and Total Station in Korea. This study has been undertaken to check whether TLS (Terrestrial Laser Scanner) could meet the accuracy standard, compare TLS survey data with those one of the new modern survey technologies such as digital aerial photogrammetry and RTK GPS. As a result, it is shown that terrestrial laser scanning and 3D stereo plot of digital aerial photogrammetry technology could meet a positional accuracy standard with artificial target. The extraction of ridges of rice paddies is, however, difficult due to the limitation of the tone colour identification and the noise of digital aerial image, and low density of the point clouds in TLS scanning. It is therefore expected that more researches into the sophisticated algorithms for the natural boundary extraction and the noise removal in digital aerial image are required. |
Apparatus and method for processing substrates | In order to optimize flow conditions in a device (1) for treating substrates (2) in a treatment basin (3) that is filled with treatment fluid, said device comprising at least one diffusor (12) to introduce the fluid into the treatment basin (3), the distance between the diffusor (12) and the substrates (2) can be regulated. The invention also relates to a method for regulating said distance. According to an additional measure to improve flow conditions in said device, the diffusor (12) has a plate (18) that is curved cylindrically toward the substrates (2) and outlets (20), the cylindrical axes thereof extending perpendicularly in relation to the planes of the substrates. |
Prediction of liquid diffusivities | Liquid diffusivities predicted using the group contribution approach in the non equilibrium stage model compared well with several semi empirical relations. The comparison showed that the average deviations of the group contribution approach were less than those of the other approaches. It is much more precise for important commercial systems such as Sulfolane/Aromatics etc. The approach can be expanded to multicomponent cases. A computer software based on the model was developed to easily predict liquid diffusivities. |
Detrusor mast cells in refractory idiopathic instability. | The diagnosis of interstitial cystitis (IC) is not usually considered in patients with idiopathic instability. Because histamine provokes detrusor contractions in vitro, we assessed detrusor mast cell counts in 29 females with refractory instability. Raised mast cell counts (greater than 28/mm2 of detrusor muscle, consistent with a histological diagnosis of IC) were found in 29% of such cases. Thus cystoscopy and bladder biopsy should be considered in patients with idiopathic instability which fails to respond to anticholinergic drugs, as alternative therapy may be useful. Patients with refractory instability and normal detrusor mast cell counts often gave a history of prolonged childhood nocturnal enuresis (55% of cases); in contrast, patients with intractable instability and abnormally high mast cell counts seldom gave such a history (12%). These trends may give some insight into the aetiology of idiopathic instability--"congenital" or acquired? |
Better Communication Research Programme | The reports from the Better Communication Research Programme (BCRP) reflect the results of a three-year research programme designed to investigate the progress of children with speech, language and communication needs over time; the support and interventions offered to them and the evidence base for them; and the perspectives of parents and children about the outcomes they value. The programme draws on evidence provided in the thematic and technical reports and considers the overall implications for policy, practice and research. It is aimed particularly at non-specialist policy makers and commissioners |

Considerations before initiating therapy in Parkinsonism: basing on the quality of life | Objective ::: Improvement of quality-of-life (QoL) has been termed as a primary objective in initiating therapy in both Parkinson’s disease (PD) and multiple system atrophy Parkinsonian subtype (MSA-P). We aimed to compare the determinants of life quality in drug naive PD and MSA-P patients. |
Preparation of methylcyclohexanol and methylcyclohexanone from aerobic oxidation of methylcyclohexane catalyzed by metalloporphyrins | The method for the preparation of methylcyclohexanone and methylcyclohexanol via selective aerobic oxidation of methylcyclohexane catalyzed by metalloporphyrin was reported for the first time.Catalyzed by Mn(Ⅲ) porphyrin, methylcyclohexane could be oxidized by air.The products were three isomers of methylcyclohexanone, 1-methylcyclohexanol and 2-methylcyclohexanol. The effect on the conversion and selectivity was investigated when reaction conditions or porphyrin structure were changed.With the alkoxyl substituting metalloporphyrins as catalysts,the selectivity of methylcyclohexanone and methylcyclohexanol was better than using TPPMnOAc.Moreover, the larger the substitute’s volume, the higher the conversion, and selectivity still remained satisfactory.Using 5,10,15,20- tetra ( para -heptaneoxylphenyl) porphyrin manganese as catalyst, the conversion was up to 20% and the overall selectivity of methylcyclohexanone and methylcyclohexanol was 76%. |
Pancreatic steatorrhea: action of a total lyophilized pancreas preparation: an "in vitro" and "in vivo" study. | A total lyophilized pig pancreas (TLP) preparation was assayed "in vitro" and "in vivo". Lipase activity of the four lots studied was 6.180 +/- 1.122 IU by gram of the commercial product. There was no free trypsin detectable in the preparation. Fifteen pancreatic exocrine insufficiency patients were studied in a period of four weeks. Adult patients received from 35.500 to 35.776 IU of lipase contained in TLP preparation by meal. All patients had their steatorrhea reduced, or normalized, stool weight reduced and body weight increased. There is not an obligatory relation between stool fat loss and stool weight. Steatorrhea decreased at least during the 14 first days of treatment before reaching a stable level. This long delay before reaching a maximum effect deserves to be known: to test the efficiency of a pancreatic extract, the treatment must be given at least two weeks before estimating its results on fecal fat excretion. |
Identification of processes having direction-dependent responses, with gas-turbine engine applications | Many processes have dynamic responses which are dependent on the direction in which the process variable is moving. The effects of such nonlinear behaviour on the weighting function model of a process obtained by cross-correlation and on the difference equation model obtained by a generalised least-squares procedure are determined theoretically for a process with first-order dynamics perturbed with pseudo-random binary signals. The theory is confirmed by results from a hybrid computer simulation, and computer-simulated results for processes with second-order dynamics are also presented. The theory is used to explain discontinuities in weighting-function models of a gas-turbine engine in which the input-transducer had direction-dependent dynamic responses. Experimental work on a pilot-scale process is reported, and further examples from the literature are examined. |
Notice of RetractionAnalysis and Calculation of 3-D Temperature Field of Submersible Motor Rotor | According to the problem of immeasurable working temperature of submersible motor, it established three-dimension finite element model of part of rotor iron core and half a rotor bearing in rotor three-dimension temperature field. The convective heat transfer coefficient between the lubrication oil in air gap of motor and rotor surface , oil of hollow shaft's were got by the heat transfer and fluid mechanics theory. According to loss value calculated by electromagnetic field and convective heat transfer coefficient on the surface, it calculated in the temperature field, and then got the temperature distribution map of rotor and relevant components. Compared finite element method with other method results, it did contrastive analysis and proved thermal field model and method accuracy. |
Fatal cardiac tamponade in malarial acute renal failure. | Uremic hemorrhagic pericarditis occurs much less frequently in acute than in chronic renal failure, but when it does, it is a potentially fatal complication. The possibility of hemorrhagic pericarditis and cardiac tamponade should be considered in patients with acute renal failure and acute hemodynamic instability. This study reports a case of falciparum malaria complicated by acute renal failure that developed fatal cardiac tamponade in the recovery phase of acute renal failure. |
CONVERSION OF EPOXIDES INTO 2-HYDROXYETHYL THIOCYANATES WITH NH4SCN IN THE PRESENSE OF 2,6-BIS[2-(O -AMINO PHENOXY)METHYL]-4-BROMO-1-METHOXYBENZENE (BABMB) AS CATALYST | A convenient and efficient procedure for the ring-opening of 1,2-epoxyethanes with ammonium thiocyanate in the presence of 2,6-bis[2-(o -aminophenoxy)methyl]-4-bromo-1-methoxybenzene (BABMB) is described. In this study, a reagent and conditions have been discovered with which the individual 2-hydroxyethyl thiocyanates can be synthesized in high yield and with more than 90% regioselectivity. Thus, several 2-hydroxyethyl thiocyanates, useful intermediates toward biological-active molecules, are easily obtained in very good yields. |
Microstructure and Hot Ductility of Austenitic Stainless Steel Crl7Mn6Ni4Cu2N in Slab Shell and Core | Tensile specimens were cut from austenitic stainless steel Cr17Mn6Ni4Cu2Nslab shell and core, and high temperature tensile tests were carried out on Thermorestor-W thermodynamic simulation tester to study microstructure and hot ductility.The results show that,the hot ductility in shell and core increasd with the increase of deformation temperature,and reachd the maximum at 1 250℃.The hot ductility of the slab shell was well,and its microstructure was fine dendrite,cracking were located in limb of ferrite dendrite.In slab core,the microstructure was composed of cellular austenitic and network ferrite,and its hot ductility was low,cracks were apt to appear in cellular austenitic.During the process of hot deformation,the cellular austenitic in slab core was easy to crack than dendrite crystal in slab shell,which leads to the low ductility in slab core. |

Impulse‐response method to predict echo responses from targets of complex geometry. Part III. Application to nondestructive testing | A theoretical model has been proposed for predicting the radiation of transient ultrasonic pulses, their scattering by targets of complex shape, and their reception. [A. Lhemery, ‘‘Impulse‐response method to predict echo responses from targets of complex geometry. Part I. Theory,’’ J. Acoust. Soc. Am. 90, 2799–2807 (1991)]. Its computer implementation and experimental validation have also been considered [A. Lhemery and R. Raillon, ‘‘Impulse‐response method to predict echo responses from targets of complex geometry. Part II. Computer implementation and experimental validation,’’ J. Acoust. Soc. Am. 95, 1790–1800 (1994)]. The accuracy of the model allows its application to a problem arising in classical NDT pulse‐echo methods, namely, the discrimination of small defects and misoriented cracks. The echo‐response from these two types of defects can produce the same B‐ or C‐scan images in certain circumstances, leading to the possibility of serious misinterpretations. First, the relative importance of both th... |
DE / CONSTRUCTION SITES : ROMANS AND THE DIGITAL PLAYGROUND | The Roman world, as attested to archaeologically and as interacted with today, has its expression in a great many computational and other media. The place of visualisation within this has been paramount. This paper argues that the process of digitally constructing the Roman world and the exploration of the resultant models are useful methods for interpretation and influential factors in the creation of a popular Roman aesthetic. Furthermore, it suggests ways in which novel computational techniques enable the systematic deconstruction of such models, in turn re-purposing the many extant representations of Roman architecture and material culture. |
