A comparative study of by-products yield from coke making processes in a Jenkner apparatus

Physico-chemical characteristics or the industrial behaviour of any coal is directly controlled by its organic micro-components (macerals). The yields of by-products during carbonization of coal are affected by organo micro-components of different coals and operating parameters, such as, charging technologies, carbonization temperature, particle size, bulk density, etc. In the present investigation, the effects of volatile matters (16.61–36.00%), Ro, avg. (0.80–1.36%), exinite (0.5–4.5%), hydrogen (4.34–5.29%) and nitrogen (1.60–2.18%) content of coal on yield of by-products, such as, coke oven gas, coal tar, ammonia, and hydrogen sulphide were studied. The studies revealed that there is a significant difference of the yield of by-products for the two different charging technologies. The coke oven gas, coal tar and ammonia yield was lower in stamp charging process as compared to top charging process, whereas, hydrogen sulphide yield followed a reverse trend.
On the Interpretation of Regression Plots

Abstract A framework is developed for the interpretation of regression plots, including plots of the response against selected covariates, residual plots, added-variable plots, and detrended added-variable plots. It is shown that many of the common interpretations associated with these plots can be misleading. The framework also allows for the generalization of standard plots and the development of new plotting paradigms. A paradigm for graphical exploration of regression problems is sketched.
Gonadoblastoma, testicular and prostate cancers, and the TSPY gene.

The role of the Y chromosome in oncogenesis of human cancers has been somewhat controversial. Both gain and loss of the Y chromosome in different leukemia, lymphoma, and solid tumors have been reported (Abeliovich et al. 1994; Brothman 1997; Dave et al. 1996; Geburek et al. 1997; Jackson-Cook et al. 1996; Kirk et al. 1994; Konig et al. 1994; Mertens et al. 1997; Riske et al. 1994; Watanabe et al. 1996). Conceivably, both oncogenes and tumor-suppressor genes exist on this chromosome, and they may act at different points during tumorigenesis, particularly for cancers of male-specific organs, such as the testis and the prostate.
Photoacoustic insight for aerosol light absorption aloft from meteorological aircraft and comparison with particle soot absorption photometer measurements: DOE Southern Great Plains climate research facility and the coastal stratocumulus imposed perturbation experiments

Aerosol light absorption can be intense close to local sources such as wildland and oil fires, with smoke that disperses into the boundary layer and, with enough lift, into the upper atmosphere where it may be transported around the globe. Filter-based methods such as the Particle Soot Absorption Photometer (PSAP) are most commonly used to quantify aerosol light absorption aloft. This paper reports first measurements of aerosol light absorption aloft with photoacoustic instrumentation (PA). Three examples of aerosol light absorption are presented. The first one illustrates a case of detached layers aloft arising from intercontinental, interoceanic transport of smoke from wildland fires in Siberia to the North American continent and the measurement campaign held at the Department of Energy Atmospheric Radiation Measurement Program Climate Research Facility in north central Oklahoma. Then, two examples of intense local fire smoke light absorption from the Coastal Stratocumulus Imposed Perturbation Experiment near Marina, California, USA, are presented. The first local fire was an oil fire burning in a storage tank near Moss Landing, California, USA, and smoke from this fire was very dark, indicating a low single scattering albedo. By contrast, the second local fire was predominantly burning wood, vegetation, and structures near Fort Ord in Marina, California, USA, and the smoke was very bright, indicating a high single scattering albedo. In all examples, PA measurements at 676 nm were compared with those from a PSAP modified to measure at three wavelengths, including 660 nm.
Dentascan imaging of the mandible and maxilla

DentaScan is a unique new computer software program which provides computed tomographic (CT) imaging of the mandible and maxilla in three planes of reference: axial, panoramic, and oblique sagittal (or cross-sectional). The clarity and identical scale between the various views permits uniformity of measurements and cross-referencing of anatomic structures through all three planes. Unlike previous imaging techniques, the oblique sagittal view permits the evaluation of distinct buccal and lingual cortical bone margins, as well as clear visualization of internal structures, such as the incisive and inferior alveolar canals. Several case reports are presented to demonstrate the clinical usefulness of DentaScan.
Probability Failure Modeling of Woven Fiber Networks

A probability model is developed to describe the failure of a biaxially loaded woven fiber network. The system under consideration consists of fibers arranged in a mutually orthogonal, simple weave pattern. The primary goal is to estimate the cumulative distribution function for failure of the network as a function of the fiber properties and the failure mechanism. The two-dimensional load sharing model is applicable to systems consisting of different fibers and various biaxial loading conditions. An al gorithm that explicitly computes the distribution function is developed and evaluated numerically. Results are qualitatively consistent with other lattice models.
Effect of storm‐time plasma pressure on the magnetic field in the inner magnetosphere

[1] We investigate the effect of plasma pressure on the magnetic field in the near-Earth magnetosphere (2 to 6.5 RE) during the major magnetic storm of October 21–25, 2001. For this we obtain a time series of “snapshots”, in each of which the magnetic forces are equilibrated by plasma pressure gradient forces. Each snapshot is computed using our 3-D equilibrium code, which is fed anisotropic pressure in the equatorial plane from a kinetic ring current model. As computational boundaries we use magnetic flux surfaces obtained from the T89 empirical model [Tsyganenko, 1989], parameterized by the appropriate Kp. We analyze the computed magnetic fields and electric currents at each stage of the storm. Our findings include significant (∼10) plasma β and large field depressions near Earth at the storm peak. The results clearly show the necessity of a magnetically self-consistent treatment of plasma transport in storm modeling.

PO-0788 ’kidneys In Crisis’ A Snapshot Of Continuous Renal Replacement Therapy In Picu, Our Lady’s Children’s Hospital, Crumlin, Dublin

Introduction Continuous Veno Venous Haemofiltration (CVVH) is the extracorporeal renal support therapy of choice in PICU at OLCHC. 1 It is an extracorporeal blood treatment where ≤8% of patients blood is passed through a haemofilter. It removes fluid and waste products from the body in a gradual and controlled way avoiding massive fluid shifts. 2 CVVH in PICU OLCHC CVVH in OLCHC has seen a considerable expansion over the last 5 years. There are currently 21 CVVH specialists, including a CVVH co-ordinator in post. 2–3 specialists are on duty every shift which ensures continuous service availability. CVVH specialists require 60 pump hours/year to maintain competency. Wet labs are used to facilitate training. CVVH is provided using the Aquarius ® which offers a paediatric mode, a safer therapy choice in children (Nikkiso, Co, Ltd). Results The CVVH service has progressively developed, as is evident in Figure 1. In 2011, 8 patients were supported with CVVH with a run time of 639 h, by 2013 this number increased to 15 patients and the run time had tripled. Discussion The progressive increase in patients supported with this therapy mirrors its remarkable growth internationally. CVVH is the most dominant form of artificial renal support in Australian and European critical care, and its role as adjuvant therapy in sepsis is attracting increased focus. 3 Conclusion CVVH activity is increasing at our institution, facilitated by a competent and flexible team of CVVH specialists. Future adequately powered multivariate logistic regression analysis should address outcomes of patients supported on CVVH.
Insular species of Afrotropical freshwater crabs (Crustacea: Decapoda: Brachyura: Potamonautidae and Potamidae) with special reference to Madagascar and the Seychelles

The evolutionary relationships between island and mainland faunas of the 24 species of insular freshwater crabs in the Afrotropical region are reviewed in the light of phylogenetic studies. Twenty insular species of freshwater crabs are endemic, and four are also found on the neighboring mainland of Africa. The Atlantic Ocean islands of Sherbro, Bioko, Principe, and Sao Tome support five species of Potamonautidae, while the Western Indian Ocean islands of the Seychelles, Zanzibar, Pemba, Mafia, and Madagascar together have 16 species of Potamonautidae, and Socotra has three species of Potamidae. Disjunct distributions of non-endemic insular species of Afrotropical freshwater crabs with conspecifics on the mainland are the result of past lower sea levels that once united islands with the coast. The presence of endemic species of freshwater crabs on oceanic volcanic islands (such as Principe and Sao Tome) separated from the mainland by deep seas is probably the result of transoceanic dispersal. Endemic genera of freshwater crabs found on oceanic ‘Gondwanan’ islands are derived from ancestral populations on the Eurasian (Socotra) or African (The Seychelles and Madagascar) mainlands that probably reached there by transoceanic dispersal, rather than their being the vicariant descendents of Gondwanan ancestors. Species of freshwater crabs found on islands in the Afrotropical region are either not unique, or are endemic at the species or genus level. The degree of endemism depends on the island’s geological history: whether it is part of the continental shelf, an oceanic island of volcanic origin, or a former part of the ancient continent of Gondwana.
Elemental sulfur-based electrodeposition of indium sulfide films

We report research on electrodeposition of indium sulfide films, with In 2 S 3 a less hazardous alternative to CdS buffer layers in solar cells. Numerous organic and aqueous/organic electrolytes of InCl 3 , NaCl, and elemental sulfur were investigated, including several glycols and amides. Temperatures ranged from 80–170 °C, and deposition voltages from −0.6 to −1.2 V (Ag/AgCl with organic filling solution). Substrates included indium tin oxide-on-glass, molybdenum, and titanium, with indium or graphite anodes. Rapid stirring was used. Deposition was sluggish in all baths. Uniformity and adherence were only moderate, with irregular coverage and cracking-and-flaking sometimes evident. The best baths were ethylene glycol or 1, 2-propanediol-based, with golden-yellow films, nominally In 2 S 3−x O x , depositing typically heavier around the substrate edges. With low temperatures and/or large currents, brown films more rich in indium sometimes formed. Cyclic voltammetry elucidated onset potentials, secondary reactions, and photoactivity, with the greatest anodic photocurrents arising from In 2 S 3 's n-type conductivity occurring with mixed ethylene glycol/propionic acid/water baths. Scanning electron microscope photographs indicated a compact small grain microstructure for yellow films. Energy dispersive X-ray analysis and photoelectron spectroscopy data indicate up
Effect of roughage restriction on serum insulin in the dairy cow.

Abstract Serum immunoreactive insulin was measured at intervals during lactation in cows consuming restricted roughage or control rations. At 16 weeks postpartum when milk fat depression was greatest, serum immunoreactive insulin was higher in the restricted roughage group. In general there was a negative relationship between serum immunoreactive insulin and milk fat production and percentage. Within treatment, however, such relationships were consistently negative on restricted roughage ration but either nil or positive on control ration. Rumen acetate:propionate ratios were negatively correlated with serum immunoreactive insulin.
A shell-model calculation for the reaction 15N(p,n)15O

Abstract The unified theory of Feshbach is applied to the reaction 15N(p,n)15O. Two open channels for the elastically scattered proton and the inelastically scattered neutron are explicitly included. The open channels are coupled by the optical isospin-dependent potential of Lane. The closed channel Hamiltonian is diagonalized in a restricted shell-model basis of one-particle-one-hole negative-parity states; the positions and widths of the resonances in 16O due to the closed channels are compared with experiment. The total neutron cross section and angular distributions are also compared with experiment. Some differential excitation functions are presented for the elastically scattered proton.
Uncertainty Quantification Integrated to the CFD Modeling of Synthetic Jet Actuators

The Point Collocation Non-Intrusive Polynomial Chaos (NIPC) method has been applied to two stochastic synthetic jet actuator problems used as test cases in the CFDVAL2004 workshop to demonstrate the integration of computationally efficient uncertainty quantification to the high-fidelity CFD modeling of synthetic jet actuators. In Case1 where the synthetic jet is issued into quiescent air, the NIPC method is used to quantify the uncertainty in the long-time averaged u and v-velocities at several locations in the flow field, due to the uniformly distributed uncertainty introduced in the amplitude and frequency of the oscillation of the piezo-electric membrane. Fifth order NIPC expansions were used to obtain the uncertainty information, which showed that the variation in the v-velocity is high in the region directly above the jet slot and the variation in the u-velocity is maximum in the region immediately adjacent to the slot. Even with a ten percent variation in the amplitude and frequency, the long-time averaged u and v velocity profiles could not match the experimental measurements at y=0.1mm above the slot indicating that the discrepancy may be due to other uncertainty sources in CFD or measurement errors. In Case 2 which includes a cross flow, the free stream velocity is treated as an uncertain input variable. Fifth degree NIPC expansions were employed to quantify the uncertainty in phase averaged velocity profiles as well as long-time averaged wall pressure and skin friction coefficient distributions. The results of Case 2 show that the uncertainty in phase averaged velocity profiles gets larger when approaching the main stream. The size of a separation bubble observed in this case remains relatively insensitive to the uncertain free stream velocity within the tolerance range considered.
Physical controls and predictability of stream hyporheic flow evaluated with a multiscale model

[1] Improved predictions of hyporheic exchange based on easily measured physical variables are needed to improve assessment of solute transport and reaction processes in watersheds. Here we compare physically based model predictions for an Indiana stream with stream tracer results interpreted using the Transient Storage Model (TSM). We parameterized the physically based, Multiscale Model (MSM) of stream-groundwater interactions with measured stream planform and discharge, stream velocity, streambed hydraulic conductivity and porosity, and topography of the streambed at distinct spatial scales (i.e., ripple, bar, and reach scales). We predicted hyporheic exchange fluxes and hyporheic residence times using the MSM. A Continuous Time Random Walk (CTRW) model was used to convert the MSM output into predictions of in stream solute transport, which we compared with field observations and TSM parameters obtained by fitting solute transport data. MSM simulations indicated that surface-subsurface exchange through smaller topographic features such as ripples was much faster than exchange through larger topographic features such as bars. However, hyporheic exchange varies nonlinearly with groundwater discharge owing to interactions between flows induced at different topographic scales. MSM simulations showed that groundwater discharge significantly decreased both the volume of water entering the subsurface and the time it spent in the subsurface. The MSM also characterized longer timescales of exchange than were observed by the tracer-injection approach. The tracer data, and corresponding TSM fits, were limited by tracer measurement sensitivity and uncertainty in estimates of background tracer concentrations. Our results indicate that rates and patterns of hyporheic exchange are strongly influenced by a continuum of surface-subsurface hydrologic interactions over a wide range of spatial and temporal scales rather than discrete processes.
High-dose edatrexate with oral leucovorin rescue: a phase I and clinical pharmacological study in adults with advanced cancer.

Our objective was to determine the maximum tolerated dose and toxicity of i.v. edatrexate with p.o. leucovorin. Thirty-one adults with advanced solid tumors received edatrexate as a 2-h infusion, once a week for 3 weeks, recycled every 28 days. p.o. leucovorin (10 mg/m2, every 6 h for 10 doses) began 24 h later. All had urinary alkalinization and p.o. hydration. Nine dosage levels ranging from 120 to 3750 mg/m2 were explored. Fatigue, epistaxis, nausea/emesis, mucositis, rash, myalgias, leukopenia, thrombocytopenia, and transient elevations of serum aspartate transferase were observed. Leukoencephalopathy with clinical manifestations occurred in two patients (one had prior cranial irradiation). Pharmacokinetic studies carried out at the 120- and 1080-mg/m2 dose levels revealed no significant difference in the elimination half-life at the two dose levels studied and no significant intrapatient variability between day 1 and day 8 edatrexate administration. Serum edatrexate levels measured using a dihydrofolate reductase inhibition assay correlated with those by high-performance liquid chromatography. Three major and two minor antitumor responses occurred. The maximum tolerated dose was 3750 mg/m2, with grade 3 or 4 leukopenia (one patient), stomatitis (one patient), and leukoencephalopathy (one patient). Because of the occurrence of leukoencephalopathy, further study of high-dose edatrexate with leucovorin rescue is not recommended.
Optimization of gas-sensitive polymer arrays using combinations of heterogeneous and homogeneous subarrays

Results for optimizing an array of conducting polymer gas sensors for sensing one of five analytes in the presence of up to four interferents are presented. The optimized array consists of subarrays of homogeneous (like) sensors contributing to a larger heterogeneous array of up to ten points (unlike sensors) in multidimensional sensor space. The optimization techniques presented here are linear, since the polymer sensors in their useful (low concentration) operating range exhibit linear and additive response characteristics. The optimization of these arrays produces maximum separability between analytes, demonstrating the trade-off between the addition of both information and variability induced by increasing the size of the heterogeneous array. Optimization results for sensing acetone, hexane, THF, toluene, and ethanol in the presence of interferents result in array sizes that are significantly less than the maximum available number of sensors (ten in the heterogeneous partition of the array). This result adds fuel to the argument that fewer sensors are better; the argument for more sensors, however, is also made in the context of the electronic nose systems where significant chemical diversity is required. Homogeneous subarrays of up to four elements each improve the separability of analytes in these optimized heterogeneous arrays by over 10% and also effectively flag broken or unhealthy sensors in a manner that is independent of analyte and concentration.
The quantitative determination of sinapine using titanium tetrachloride. Comments relating to the specificity of the method

A comparison has been made between two published methods (Reinecke salt method and titanium tetrachloride method) for the analysis of sinapine in rapeseed meal and its fractions. The results obtained cast doubt upon the specificity of the recently described method using titanium tetrachloride. The problem appears to arise through incomplete removal of interfering phenolic compounds prior to the colorimetric analysis.
Thermal Analysis of Elastohydrodynamic Lubrication of Line Contacts Using the Ree-Eyring Fluid Model

A thermal Reynolds-Eyring equation is derived for elastohydrodynamic lubrication of line contacts. A control volume approach is used to analyze the inlet region where back-flow occurs. Numerical results are obtained and used to develop a formula for the thermal and non-Newtonian (Ree-Eyring) film thickness reduction factor. Results for maximum temperatures and traction coefficients are also presented. The pressure dependence of lubricant thermal conductivity is found to significantly affect the maximum lubricant temperature.
Counting and addition cannot express deterministic transitive closure

An important open question in complexity theory is whether the circuit complexity class TC/sup 0/ is (strictly) weaker than LOGSPACE. This paper considers this question from the viewpoint of descriptive complexity theory. TC/sup 0/ can be characterized as the class of queries expressible by the logic FOC(<, +, /spl times/), which is first-order logic augmented by counting quantifiers on ordered structures that have addition and multiplication predicates. We show that in first-order logic with counting quantifiers and only an addition predicate it is not possible to express "deterministic transitive closure" on ordered structures. As this is a LOGSPACE-complete problem, this logic therefore fails to capture LOGSPACE. It also directly follows from our proof that in the presence of counting quantifiers, multiplication cannot be expressed in terms of addition and ordering alone.
Safety and Effectiveness of a “Percutaneous-First” Approach to Endovascular Aortic Aneurysm Repair

Background Percutaneous endovascular aneurysm repair (PEVAR) has been increasingly used in the endovascular treatment of abdominal aortic aneurysms. Furthermore, the percutaneous approach can be used with minimal sedation and local anesthesia in most cases. The purpose of this study was to assess the safety and effectiveness of a “percutaneous first” approach to femoral access for EVAR. Method From 2012 to 2014, PEVAR has been the preferred approach to femoral access for EVAR at our institution. Retrospective review of institutional vascular quality initiative data was used to compare outcomes with elective PEVAR to a contemporary institutional series of elective EVAR via open femoral exposure. These 2 patient groups were compared with assess perioperative outcomes, procedural details (including anesthesia modality, procedure time, and length of stay [LOS]) and access-related complications between groups. Results One hundred two consecutive patients underwent attempted PEVAR and were compared with 98 patients undergoing surgical femoral exposure. Demographics and comorbidities were similar between groups, although there was a greater proportion of smokers in the PEVAR group (76.5% vs. 63.3%; P = 0.04). PEVAR was associated with an increased utilization of local anesthesia (67.6% vs. 12.2%; P P = 0.035), shorter procedure times (137 vs. 222 min; P P P = 0.09). There were significantly more hematomas in the PEVAR group (9.8% vs. 2.0%, P = 0.02). However, there were no significant differences in overall postoperative complications, wound infection, or ICU LOS. Conclusions A “PEVAR first” approach proved feasible in the overwhelming majority of patients. Conversion to open transfemoral exposure was rare. PEVAR facilitated endovascular abdominal aortic aneurysm repair under local anesthesia in most patients and resulted in decreased procedural morbidity and resource utilization.
Methodology for Studying Effect of Cooling Rate During Laser Deposition on Microstructure

The present paper focuses on the effect of cooling rate and other processing variables on microstructure and mechanical properties. A specially designed, namely “step shape,” was used in the current study. The influences of the step thickness were investigated. Results show that the cooling rate is different at different steps and changes the solidification of the deposition process. The cooling rate was deliberately controlled by employing the substrate of varied dimensions. Thermocouples were used to measure the local temperature of the substrate during the deposition process and cooling stage until it reached room temperature. The results of the temperature-time relationship proved the difference in cooling rate. The influence of the substrate dimension on the microstructure and mechanical properties was investigated. The differed cooling rate led to varied grain size and resulted in affected varied hardness and tensile strength. The small samples possessed larger grains sizes formed by a slower cooling rate. The results open the possibility to acquire continuous varied microstructure and mechanical properties by employing a “step shape” substrate.
Stm Studies of GMR Spin Valves

We have investigated the surface roughness and the grain size in giant magnetoresistance (GMR) spin valve multilayers of the general type: FeMn/Ni80Fe20Co/Cu/Co/Ni80Fe20 on glass and aluminum oxide substrates by scanning tunneling microscopy (STM). The two substrates give very similar results. These polycrystalline GMR multilayers have a tendency to exhibit larger grain size and increased roughness with increasing thickness of the metal layers. Samples deposited at a low substrate temperature (150 K) exhibit smaller grains and less roughness. Valleys between the dome-shaped individual grainsare the dominant form of roughness. This roughness contributes to the ferromagnetic, magnetostatic coupling in these films, an effect termed “orange peel” coupling by Neel. We have calculated the strength of this coupling, based on our STM images, and obtain values generally within about 20% of the experimental values. It appears likely that the ferromagnetic coupling generally attributed to so-called “pinholes” in the Cu when the Cu film thickness is too small is actually “orange peel” coupling caused by these valleys.
Reflections on the Terri Schindler-Schiavo Case

Despite the enormous attention it received, the Terri Schindler-Schiavo litigation is not legally significant. The litigation involved the application of a fairly well-settled legal framework. This framework permitted, however, an unjust result. The controversy over Terri’s fate has, though, helped to focus attention on a consensus that is in need of re-examination. This paper explores the lessons that ought to be learned from the Terri Schindler-Schiavo litigation. After briefly discussing the basic facts and the complex litigation history, the paper considers the relevant federal constitutional and Florida law. The paper then critiques Florida law and explains the legal and moral considerations that ought to inform the re-examination that is so sorely needed. The most important effort needed is to restore the sanctity of life ethic.
Minimally Invasive Spinal Surgery with Intraoperative Image-Guided Navigation

We present our perioperative minimally invasive spine surgery technique using intraoperative computed tomography image-guided navigation for the treatment of various lumbar spine pathologies. We present an illustrative case of a patient undergoing minimally invasive percutaneous posterior spinal fusion assisted by the O-arm system with navigation. We discuss the literature and the advantages of the technique over fluoroscopic imaging methods: lower occupational radiation exposure for operative room personnel, reduced need for postoperative imaging, and decreased revision rates. Most importantly, we demonstrate that use of intraoperative cone beam CT image-guided navigation has been reported to increase accuracy.
Noninvasive Diagnosis of Extracranial Cerebrovascular Disease

Noninvasive methods for diagnosis of carotid and vertebrobasilar disease may be divided into passive techniques and those in which the body is interrogated by the introduction of some sort of signal such as an ultrasound beam. Older techniques have been of limited value, whereas newer noninvasive methods can give specific, accurate, and quantitative information as to the location and extent of arterial stenosis.
Monocyte-produced prostaglandin induces Fcγ receptor expression on human T cells

Abstract Incubation of human T cells for 18 hr with prostaglandin E2 (PGE2 3 × 10−6M) causes a slight but significant increase in the percentage of Tγ cells and a reduction in Tμ cells. When PGE was added to “non-Tγ” cells, the increase in the percentage of Tγ cells was more marked (from 1.5% Tγ without PGE to 11% Tγ with PGE2, P
Creating Agile Organizations Through IT: The Influence of Internal IT Service Perceptions on IT Service Quality and IT Agility

Businesses continue to make large investments in information technology (IT) resources, and it is crucial for them to implement effective management strategies to better leverage these resources. Modern organizations are increasingly dependent on IT to remain agile and competitive in a rapidly changing market, but there remain gaps in understanding how IT resources support IT agility. Recent IT strategy research highlights the role of IT service climate in driving positive IT service quality, and we extend this work in the form of a theoretical model that relates an organization’s internal IT service perceptions to IT agility. We hypothesize a partially mediated relationship wherein internal IT service perceptions positively affects IT agility, both directly and indirectly, through facilitating positive IT service quality, highlighting the crucial role of IT personnel and their service orientation in provisioning services to enable IT agility. We test our model with an unmatched survey of 400 full-time IT managers and professionals and find strong support for our hypotheses. Our results have important implications for future research and practice, as the IT community continues to seek to adopt effective strategies for managing and leveraging its expensive resources.
Millennials in the Transportation Workforce

Generational differences in the United States are of increasing concern to human resource professionals as they prepare to manage the rapid demographic shifts expected in the transportation workforce. As baby boomers retire and millennials increase their share of the workforce, transportation agencies are seeking better understanding of the workplace attributes that will be most successful in attracting and retaining millennials. This paper contextualizes challenges faced by state departments of transportation within the current research literature on generational differences to identify mutual concerns in addition to successful strategies that state agencies can employ to attract and retain young staff. A literature review was conducted in conjunction with focus group discussions. Six staff from human resource departments representing five state departments of transportation (Alaska, Minnesota, Montana, Oregon, and Wisconsin) participated. The study found that state departments of transportation offer ma...
Transgresiones cubanas: Ofelia Rodríguez y la mujer/nación independiente y lésbica

El ensayo examina tres de las novelas mas importantes de la escritora cubana Ofelia Rodriguez Acosta (1902-1975) El triunfo de la debil presa (1925), La vida manda (1928), y Sonata interrumpida (1940). El analisis parte de la tesis de que estas obras son un reto a la imagen de la naciente nacion cubana que desde los primeros momentos se baso en la idea de la familia heterosexual como la unidad social y economica central de la sociedad. Su reto abrio las puertas en Cuba desde la literatura para formular un ideal de la nacion cubana que incluyese una pluralidad de genero. Dado que el camino hacia ese ideal ha sido lento, tortuoso, e incompleto aun, el examen de la obra de esta autora pionera, silenciada en la Cuba revolucionaria hasta muy recientemente, tiene importancia crucial para reivindicar un pasado que puede dar mas raices a un futuro inclusivo.
Seizure Freedom after Leucotomy in a Childhood Refractory Epilepsy Associated with Schizencephaly and Multifocal Cortical Malformation

Schizencephaly associated with extensive malformation of cortical developments frequently cause medically intractable epilepsy in pediatric patients. Because of the extent of the structural abnormality, which is often bihemispheric and multifocal, epileptic surgery in these group of patients is typically not considered or indicated. We report a 10-year-old boy with medically intractable epilepsy and multifocal epileptiform discharges associated with bilateral malformation of cortical developments, schizencephaly, and agenesis of the corpus callosum, initially thought to be not a candidate for epilepsy surgery. All of the seizures localized to the right posterior head region. Seizure freedom was achieved after a right temporoparietooccipital (TPO) disconnection. He was followed postoperatively for 22 months at which time he remained on oxcarbazepine monotherapy. We emphasize that medically intractable epileptic patients with unilateral schizencephaly, bilateral colpocephaly, and multifocal epileptiform discharges must be evaluated with a video electroencephalography (VEEG) to characterize the seizures before ruling out epilepsy surgery as a therapeutic option. TPO disconnection surgery, instead of multilobar resections, can result in favorable seizure outcome in patients with localized seizure onset in the posterior head region.
On the independence of singular multivariate skew-normal sub-vectors

Abstract This article provides necessary and sufficient conditions that characterize independence among sub-vectors of a singular multivariate skew-normal random vector.
Packet communication technology for advanced wireless networks

Two techniques for future (third-generation) wireless networks are described. They are a switching architecture, referred to as a cellular packet switch, and a packet transmission technique, referred to as packet-reservation multiple access. It is shown how the two can work together to meet the demands of third-generation wireless networking. As a network design example, a dual-bus metropolitan area network to be standardized as IEEE 802.6 is considered. >
Changes in quality of life after elective surgery: an observational study comparing two measures

Purpose Our main objective was to compare the change in a validated quality of life measure to a global assessment measure. The secondary objectives were to estimate the minimum clinically important difference (MCID) and to describe the change in quality of life by surgical specialty.
Three dimensional crack propagation through mesh-based explicit representation for arbitrarily shaped cracks using the extended finite element method

Abstract In this study a three-dimensional extended finite element modeling work is developed for crack propagation analysis of arbitrarily shaped crack(s) under mixed mode loading conditions. An explicit method is proposed for crack geometry characterizations, slicing of the enriched elements, and crack propagations. The method can be used to model multiple cracks propagation and allows for crack geometry transition from internal to surface, and further to through-thickness modalities under arbitrary loading conditions. Benchmark cases are studied and satisfactory agreement between theoretical and numerical results is observed. In addition, comparison between fully explicit and conventional implicit methods is made at different finite element mesh densities. The results show that compared to the conventional implicit method, there is a significant improvement in the obtained stress intensity factors for the fully explicit method at coarse linear hexahedral and quadratic tetrahedral meshes.
Shipman theory in behavioural economics : a review of theory and empirical work

Decisions involving consumers' choices made in the market are not strictly rational but on many occasions they are influenced by social, cognitive, psychological and emotional factors. These decisions have consequences for market prices, resource allocation, and returns. The aim of the study was to test a hypothesis and consequently to develop or modify a theory that challenges the principle that human rationality is not the only thing that controls market decisions but also other non logic factors such as sentimental affection behaviours do affect decisions. The method used was the interview method coupled with case study approach. Furthermore, other strategic interaction methods such as observation techniques were made in a Ghanaian Harbour. Results show that when individuals make choices and decisions in market transactions, which are connected with human beings and they also have economic consequences, they are influenced by whether they have sentimental affection with them or not. Lack of sentimental affection with persons compels consumers to demand for magnitude needs that are appraised as powerful rational incentives in the determination of economic transactions. The conclusion is that behavioural economics assumptions are supported by the findings of the study, especially, the concept that people often make decisions based on approximate rules of thumb and not strict logic. In this essay one also sees market inefficiencies concerning the mispricing and non-rational decision making that occur in the market during day to day business activities.
Midface Distraction: Orthodontic Considerations

Distraction osteogenesis has become an important clinical tool in craniofacial surgery. Initially applied to lengthening of the human mandible [1], the technique has subsequently been used to reconstruct all components of the craniofacial skeleton, including the maxilla, zygoma, and cranial vault. One of the most beneficial applications of distraction has been advancement of the midface in patients with cleft lip and palate, midface hypoplasia, and craniosynostosis syndromes.
Eliminating Physiological Information from Facial Videos

Vital signs, cognitive load, and stress can be remotely measured from human faces using video-capturing devices under ambient light, which raises both wide applications and privacy issues. To avoid immoral use of this technology, there is a need for methods to eliminate physiological information from facial videos without affecting their visual appearance. To meet the need, we develop a novel algorithm based on motion component magnification that inputs a video and outputs its replica with physiological signals removed. Facial video data has been collected from 18 participants in a study to assess the performance of our algorithm in thwarting heart rate measurement based on remote photoplethysmography. Our results show that the mean absolute error of heart rate measurement averaged among participants was increased from 0.254 beats per minute to above 17 beats per minute without causing visible artifact. This is the first demonstration of an algorithm that can achieve this kind of functionality.
Parallelization of the WASH123D Code—Phase III: 1-Dimensional Channel, 2-Dimensional Overland, and 3-Dimensional Subsurface Flows

Watershed models are used to simulate and predict major hydrological processes, such as surface or subsurface flows, which may occur on different spatial domains and temporal scales. A key feature of watershed models is the ability to model interactions among different processes and domains. Such interactions can be strongly or weakly coupled depending on the relevant time scales for each process. WASH123D is a first-principles, physics-based model for simulating a coupled system of channel flow, overland flow, and subsurface flow. A parallel version, pWASH, has been used for the calibration, validation, and evaluation of proposed alternatives of the Biscayne Bay Coastal Wetlands project. The goal is to rehydrate wetlands using the best alternative based on the simulation results. In the pWASH code, channel flow is modeled as a one-dimensional (1-D) channel network, overland flow as a 2-D process, and subsurface flow as a 3-D process. Different algorithms are implemented to account for the interactions between these different domains. The pWASH code is designed to tackle large watershed problems on parallel high performance computers. A software-engineering approach was used to efficiently parallelize the complex coupling algorithms. The resulting software toolkit encapsulates the parallel data structures and message passing required for multi- domain/process interactions. In this paper, the authors briefly describe the numerical methods in WASH123D, the parallelization of pWASH, and the scalability of coupled flow problems running on parallel high performance computers.
Dual language learning, inhibitory control, and math achievement in Head Start and kindergarten

Abstract This study examined whether developmental patterns of inhibitory control (IC) and kindergarten math achievement differed among Head Start children with varying dual language learning status. This study further explored the potential mediation effects of IC development as an explanation of differences in kindergarten math skills across children with varying dual language learning status. Based on their English skills and home language use, children’ dual language learning status was categorized into (1) Spanish-English bilingual children, (2) Spanish-English dual language learners with limited English skills (DLLs-LES), and (3) English-monolingual children. Analyses were conducted using data from the Head Start Family and Child Experiences Survey (FACES) 2009 Cohort. Results showed that bilingual children presented greater IC at Head Start entry than DLLs-LES and faster growth in IC through kindergarten (1.5 years) than English-monolingual children. Bilingual children also outperformed monolingual children and DLLs-LES in math at kindergarten, despite the fact that they had lower baseline math skills than monolingual children. DLLs-LES, on average, presented the lowest IC skills and math skills through kindergarten. DLLs-LES, however, presented faster growth in IC than English-monolingual children through kindergarten. The achievement gaps in math among the three groups were explained by relative differences in IC development among the groups. The current study with low-income preschoolers supported emerging literature suggesting the benefits of bilingualism for cognitive skills and learning. Study implications are discussed.
(π +/- ,xn) reactions

Cross sections for the formation of the $^{76}\mathrm{Ge}{({\ensuremath{\pi}}^{+},xn)}^{76\ensuremath{-}x}\mathrm{As}$ and the $^{76}\mathrm{Se}{({\ensuremath{\pi}}^{\ensuremath{-}},xn)}^{76\ensuremath{-}x}\mathrm{As}$ reaction products were determined for values of $x$ up to six for both 100 and 180 MeV pions. The ${\ensuremath{\pi}}^{\ensuremath{-}}$ induced cross sections were consistently higher than those induced by ${\ensuremath{\pi}}^{+}$ for all nonzero values of $x$. Both the ${\ensuremath{\pi}}^{\ensuremath{-}}$ and ${\ensuremath{\pi}}^{+}$ induced cross sections appear to reach a maximum value when $x$ equals 2 or 3. The results are compared to predictions based on cascade-evaporation calculations and discussed in terms of possible mechanisms. Combining the experimental results for $x=5 \mathrm{and} 6$ with these calculations it was concluded that no significant difference exists in the excitation energy spectrum following ${\ensuremath{\pi}}^{+}$ or ${\ensuremath{\pi}}^{\ensuremath{-}}$ interaction.
Personalized Medicine in Nasal Delivery: The Use of Patient-Specific Administration Parameters To Improve Nasal Drug Targeting Using 3D-Printed Nasal Replica Casts.

Effective targeting of nasal spray deposition could improve local, systemic, and CNS drug delivery; however, this has proven to be difficult due to the anatomical features of the nasal cavity, including the nasal valve and turbinate structures. Furthermore, nasal cavity geometries and dimensions vary between individuals based on differences in their age, gender, and ethnicity. The effect of patient-specific administration parameters was evaluated for their ability to overcome the barriers of targeted nasal drug delivery. The nasal spray deposition was evaluated in 10 3D-printed nasal cavity replicas developed based on the CT-scans of five pediatric and five adult subjects. Cromolyn sodium nasal solution, USP, modified with varying concentrations of hypromellose was utilized as a model nasal spray to evaluate the deposition pattern from formulations producing a variety of plume angles. A central composite design of experiments was implemented using the formulation with the narrowest plume angle to determin...
Design of a Portable Micro-Dilution Tunnel Particulate Matter Emissions Measurement System

The Federal Test Procedure (FTP) for heavy-duty engines requires the use of a full-flow tunnel based constant volume sampler (CVS). These are costly to build and maintain, and require a large workspace. A small portable micro-dilution system that could be used on-board, for measuring emissions of in-use, heavy-duty vehicles would be an inexpensive alternative. This paper presents the rationale behind the design of such a portable particulate matter measuring system. The presented micro-dilution tunnel operates on the same principle as a full-flow tunnel, however given the reduced size dilution ratios can be more easily controlled with the micro dilution system. The design targets dilution ratios of at least four to one, in accordance with the ISO 8178 requirements. The unique features of the micro-dilution system are the use of only a single pump and a porous sintered stainless steel tube for mixing dilution air and raw exhaust sample. This paper contains the results of that design process.
Performance and design of MgF2 + Au coatings on aluminum mirrors: enabling far-ultraviolet solar occultation measurements for Europa-UVS

Europa-UVS plans to characterize the Europan exosphere by performing solar occultation measurements at key points during the Europa Clipper mission. Observing the Sun from Jovian space requires a system with high dynamic range. The high end of the dynamic range of the Europa-UVS MCP-XDL detector is limited by dead time effects and is rated at ~ 300 kHz, corresponding to a 150 nm) of the Europa-UVS bandpass (55-210 nm). To reduce the input photon flux in the Europa-UVS optical train, we propose applying a thin MgF2 overcoat on the heritage bare gold solar port mirror adopted from the New Horizons Alice solar occultation channel and the JUICE-UVS solar port. The MgF2 layer, with the distinct advantage as the standard coating on the other heritage optics for Europa-UVS, suppresses the reflectance of the solar port mirror, especially above 140 nm, compensating the solar photon flux increase. The decrease in reflectance has been modeled using Fresnel reflectance theory and verified experimentally by comparing reflectance of Au and MgF2-Au mirrors. With the implementation of the MgF2 layer together with a reduction in the solar port aperture size, we predict global count rates that are well-matched to the 300 kHz threshold of the Europa-UVS detector.
