Neogene calc-alkaline extrusive and intrusive rocks of the karalar-yesiller area: Northwest Anatolia, Turkey

The Karalar-Yesiller area lies on the estern flank of the Kazda $$\bar g$$ i massif in northwestern Anatolia (Asiatic Turkey), and includes about 600 square kilometers, of which approximately 80% is covered by rhyodacite-quartz latite extrusive rocks, and a comagmatic granodiorite-quartz monzonite batholith, and stocks, all of middle Miocene age. Extrusive rocks consist chiefly of rhyodacite lava flows of the Hallaclar Formation and quartz latite-rhyodacite ash-flow tuff, lava, and mudflow deposits of the overlying Dede Tepe Formation. These volcanic rocks lie on a basement composed, in asceding stratigraphic order, of: 1) pre-Permian Kalabak sequence, 2) Upper Triassic Halilar Formation, 3) post-Upper Triassic Ba $$\bar g$$ burun Formation, and 4) allochthons of middle Permian: and Upper Jurassic limestone. Intrusion of a granodiorite-quartz monzonite batholith during the middle Miocene was accompanied or shortly followed by extensive alteration and base metal mineralization of the Hallaclar and older rocks. Intrusion of six rhyodacitequartz latite stocks followed the main phase of hydrothermal alteration. At least one of these stocks may have contributed material to the Dede Tepe Formation of middle Miocene age. Field relations, petrologic, and geochemical data as well as radiometric age dates suggest that the intrusive and extrusive rocks are comagmatic. Parent magma is probably derived from partial melting of subducted oceanic crust and accompanying oceanic sediments. Geologic relations locally indicate assimilation of sialic crust by the grandiorite-quartz monzonite batholith.
Carbon isotopes in globular clusters down to the bump in the luminosity function

We find that the 12C/13C ratio evolves from high values (>20) below the bump in the luminosity function (BLF) to near the equilibrium value of the CNO cycle above the BLF in the globular clusters (GCs) NGC 6528 and M4. This is the first time that the predicted decline of the 12C/13C ratios due to the extra mixing at the BLF is detected in a GC. In M4, a slight decline from 12C/13C = 10 just above the BLF at MV = +0.5 to 12C/13C = 4 at MV = -0.6 is detected, suggesting that some additional mixing may occur beyond the BLF in this cluster. Isotope ratios are measured and found to be constant in the GCs NGC 6553 and 47 Tucanae down to just above the BLF of those GCs.
Atypical distinctive dermal clear cell mesenchymal neoplasm arising in the scalp

Distinctive dermal clear cell mesenchymal neoplasm (DDCCMN) is a newly described entity characterized by a dermal proliferation of neoplastic cells with clear to reticulated cytoplasm and vesicular nuclei. Atypical features in the form of nuclear pleomorphism and mitoses may be found. The histogenesis of these neoplastic clear cells is not currently known but they are thought to be mesenchymal in origin. Immunohistochemically, they stain positively for NKI-C3 and negatively for melanocytic, epithelial and lymphoid markers. All five cases originally reported by Lazar and Fletcher occurred in the lower extremities. We report herein a case of DDCCMN with atypical features arising in the scalp.
Macronutrient (N, P, K) and Redoximorphic Metal (Fe, Mn) Allocation in Leersia oryzoides (Rice Cutgrass) Grown Under Different Flood Regimes

Vegetated drainages are an effective method for removal of pollutants associated with agricultural runoff. Leersia oryzoides, a plant common to agricultural ditches, may be particularly effective in remediation; however, research characterizing responses of L. oryzoides to flooding are limited. Soil reduction resulting from flooding can change availability of nutrients to plants via changes in chemical species (e.g., increasing solubility of Fe). Additionally, plant metabolic stresses resulting from reduced soils can decrease nutrient uptake and translocation. The objective of this study was to characterize belowground and aboveground nutrient allocation of L. oryzoides subjected to various soil moisture regimes. Treatments included: a well-watered and well-drained control; a continuously saturated treatment; a 48-h pulse-flood treatment; and a partially flooded treatment in which water level was maintained at 15 cm below the soil surface and flooded to the soil surface for 48 h once a week. Soil redox potential (Eh, mV) was measured periodically over the course of the 8-week experiment. At experiment termination, concentrations of Kjeldahl nitrogen, phosphorus (P), potassium (K), iron (Fe), and manganese (Mn) were measured in plant tissues. All flooded treatments demonstrated moderately reduced soil conditions (Eh < 350 mV). Plant Kjeldahl nitrogen concentrations demonstrated no treatment effect, whereas P and K concentrations decreased in aboveground portions of the plant. Belowground concentrations of P, Mn, and Fe were significantly higher in flooded plants, likely due to the increased solubility of these nutrients resulting from the reductive decomposition of metal–phosphate complexes in the soil and subsequent precipitation in the rhizosphere. These results indicate that wetland plants may indirectly affect P, Mn, and Fe concentrations in surface waters by altering local trends in soil oxidation–reduction chemistry.
Rotational Rest Frequencies for CrO (X 5Πr) and CrN (X 4Σ

The pure rotational spectra of CrO (X 5Πr) and CrN (X 4Σ-) have been recorded using millimeter/submillimeter-wave spectroscopy in the frequency range 248-636 GHz. These radicals were created by the reaction of chromium vapor, produced in a Broida-type oven, with N2O or NH3 under DC discharge conditions. For CrO, 12 rotational transitions were recorded, in which up to five spin-orbit components were observed—the first measurement of the pure rotational spectrum of a molecule in a 5Π electronic state. Nine rotational transitions were recorded for CrN; here all four spin components were measured in every transition. The data obtained for both radicals were analyzed using an appropriate effective Hamiltonian. The resulting spectroscopic parameters of these species were determined to high precision, including those related to fine structure and lambda doubling. This work will enable radioastronomical searches for CrN and CrO to be carried out. CrO has already been observed in the optical spectra of stellar atmospheres.
The effect of urban trees on the rental price of single-family homes in Portland, Oregon.

Abstract Few studies have estimated the effect of environmental amenities on the rental price of houses. We address this gap in the literature by quantifying the effect of urban trees on the rental price of single-family homes in Portland, Oregon, USA. We found that an additional tree on a house's lot increased monthly rent by $5.62, and a tree in the public right of way increased rent by $21.00. These results are consistent with a previous hedonic analysis of the effects of trees on the sales price of homes in Portland, which suggests that homeowners and renters place similar values on urban trees.

Differential effect of tetrazolium dyes upon bacteriophage plaque assay titers

This study examined whether the practice of incorporating either tetrazolium red or tetrazolium violet dye into plaque assay medium deleteriously influences plaque assay titers. Representative members of six different virus families were studied: Cystoviridae (varphi6), Leviviridae (MS2), Microviridae (varphiX174), Myoviridae (T2), Podoviridae (P22), and Siphoviridae (Denver, T1, and VD13). Each of the members of the Podoviridae and Siphoviridae families appeared to be suppressed by either one or both dyes at a 300-mug/ml concentration. The chosen representatives of the other bacteriophage families were not suppressed by either dye at a 300-mug/ml concentration. Subsequent trials revealed no suppression of Podoviridae or Siphoviridae plaque assay titers when members of these virus families were tested with the same two dyes at the lower concentrations of 150 and 50 mug/ml. Interestingly, the bacteriophage families whose members were affected by the dyes have additional commonality in that they are the two bacteriophage families whose members possess both double-stranded DNA genomes and noncontractile tails.

Differential Gene Expression in Ovarian Carcinoma : Identification of Potential Biomarkers

Ovarian cancer remains the fifth leading cause of cancer death for women in the United States. In this study, the gene expression of 20 ovarian carcinomas, 17 ovarian carcinomas metastatic to the omentum, and 50 normal ovaries was determined by Gene Logic Inc. using Affymetrix GeneChip HU_95 arrays containing ∼12,000 known genes. Differences in gene expression were quantified as fold changes in gene expression in ovarian carcinomas compared to normal ovaries and ovarian carcinoma metastases. Genes up-regulated in ovarian carcinoma tissue samples compared to more than 300 other normal and diseased tissue samples were identified. Seven genes were selected for further screening by immunohistochemistry to determine the presence and localization of the proteins. These seven genes were: the β8 integrin subunit, bone morphogenetic protein-7, claudin-4, collagen type IX α2, cellular retinoic acid binding protein-1, forkhead box J1, and S100 calcium-binding protein A1. Statistical analyses showed that the β8 integrin subunit, claudin-4, and S100A1 provided the best distinction between ovarian carcinoma and normal ovary tissues, and may serve as the best candidate tumor markers among the seven genes studied. These results suggest that further exploration into other up-regulated genes may identify novel diagnostic, therapeutic, and/or prognostic biomarkers in ovarian carcinoma.
DRAMMS: Deformable Registration via Attribute Matching and Mutual-Saliency Weighting

A general-purpose deformable registration algorithm referred to as "DRAMMS" is presented in this paper. DRAMMS adds to the literature of registration methods that bridge between the traditional voxel-wise methods and landmark/feature-based methods. In particular, DRAMMS extracts Gabor attributes at each voxel and selects the optimal components, so that they form a highly distinctive morphological signature reflecting the anatomical context around each voxel in a multi-scale and multi-resolution fashion. Compared with intensity or mutual-information based methods, the high-dimensional optimal Gabor attributes render different anatomical regions relatively distinctively identifiable and therefore help establish more accurate and reliable correspondence. Moreover, the optimal Gabor attribute vector is constructed in a way that generalizes well, i.e., it can be applied to different registration tasks, regardless of the image contents under registration. A second characteristic of DRAMMS is that it is based on a cost function that weights different voxel pairs according to a metric referred to as "mutual-saliency", which reflects the uniqueness (reliability) of anatomical correspondences implied by the tentative transformation. As a result, image voxels do not contribute equally to the optimization process, as in most voxel-wise methods, or in a binary selection fashion, as in most landmark/feature-based methods. Instead, they contribute according to a continuously-valued mutual-saliency map, which is dynamically updated during the algorithm's evolution. The general applicability and accuracy of DRAMMS are demonstrated by experiments in simulated images, inter-subject images, single-/multi-modality images, and longitudinal images, from human and mouse brains, breast, heart, and prostate.
Tracking control of a piezoceramic actuator with hysteresis compensation using inverse Preisach model

This paper presents the classical Preisach hysteresis modeling and tracking control of a curved pre-stressed piezoceramic patch actuator system with severe hysteresis. The actuator is also flexible with very small inherent damping. It has potential applications in active antennas. A series of tests are conducted to study the hysteresis properties of the piezoceramic actuator system. The numerical expressions of the classical Preisach model for different input variations are presented. The classical Preisach model is applied to simulate the static hysteresis behavior of the system. Higher order hysteresis reversal curves predicted by the classical Preisach model are verified experimentally. The good agreement found between the measured and predicted curves showed that the classical Preisach model is an effective mean for modeling the hysteresis of the piezoceramic actuator system. Subsequently, the inverse classical Preisach model is established and applied to cancel the hysteresis the piezoceramic actuator system for the real-time microposition tracking control. In order to improve the control accuracy and to increase damping of the actuator system, a cascaded PD/lead-lag feedback controller is designed with consideration of the dynamics of the actuator. In the experiments, two cases are considered, control with major loop hysteresis compensation, and control with minor loop hysteresis compensation. Experimental results show that RMS tracking errors are reduced by 50% to 70% if the hysteresis compensation is added in the feedforward path in both cases. Therefore, hysteresis compensation with the feedback controller greatly improves the tracking control accuracy of the piezoceramic actuator.
Spikes, BOLD, attention, and awareness: a comparison of electrophysiological and fMRI signals in V1.

Early fMRI studies comparing results from fMRI and electrophysiological experiments support the notion that the bloodoxygen level-dependent (BOLD) signal reliably follows the spiking activity of an underlying neuronal population averagedacross a small region in space and a brief period in time. However, more recent studies focusing on higher level cognitivefactors such as attention and visual awareness report striking discrepancies between the fMRI response in humans andelectrophysiological signals in macaque early visual areas. Four hypotheses are discussed that can explain thediscrepancies between the two methods: (1) the BOLD signal follows local ﬁeld potential (LFP) signals closer than spikes,and only the LFP is modulated by top-down factors, (2) the BOLD signal is reﬂecting electrophysiological signals that areoccurring later in time due to feedback delay, (3) the BOLD signal is more sensitive than traditional electrophysiologicalmethods due to massive pooling by the hemodynamic coupling process, and ﬁnally (4) there is no real discrepancy, andinstead, weak but reliable effects on ﬁring rates may be obscured by differences in experimental design and interpretation ofresults across methods.Keywords: spikes, BOLD, attention, awareness, fMRI, V1, hemodynamics, monkey, humanCitation: Boynton, G.

A primary health care approach using Hispanic outreach workers as nurse extenders.

Abstract In an effort to improve the health of Hispanic families, particularly prenatal women and infants, the county health department instituted a program of intensified home visits using bilingual, bicultural nurse extenders within a framework of primary health care. The outreach workers offer basic health information to improve families' skills and knowledge, and to assist with linkages to community resources. Public health nurses provide assessment, establish a plan of care, evaluate progress, and supervise the workers. The program has resulted in increased numbers of individuals receiving services, more women registering earlier for prenatal care and the Women, Infants, and Children's (WIC) program, and increased numbers of infants receiving WIC services and regular medical supervision. Public health nurses report increased knowledge and positive changes in families' health behaviors. In addition, the program has strengthened relationships between the health department and Hispanic families.
Formability of a more randomly textured magnesium alloy sheet: Application of an improved warm sheet formability test

The warm formability of three sheet magnesium alloys was measured using the OSU formability test adapted for testing at elevated temperatures under isothermal conditions. The adapted test is shown to reliably enforce plane strain tension over a significant fraction of the sample, thus providing an assessment of FLD(0), typically the minimum major strain value on a forming limit diagram. By mathematically modeling the strain as a function of punch displacement, a case is made that the punch displacement itself provides an expedient approach to ranking the relative formability of sheet metals. Combined with knowledge of the constitutive behavior of the material, the punch displacement–strain relationship provides an explanation for the observed shape of the punch load versus displacement curves. OSU formability test results show that a new magnesium sheet alloy, yttrium-containing ZW41, is significantly more formable than traditional magnesium alloys AZ31 and ZK10. The improvement is linked to a more random texture in the new alloy, which diminishes the tendency for gross, catastrophic shear instability typical of the strongly textured traditional alloys.
Buprenorphine adoption in the National Drug Abuse Treatment Clinical Trials Network

The National Drug Abuse Treatment Clinical Trials Network (CTN), a collaborative federal research initiative that brings together universities and community-based treatment programs (CTPs), has conducted multiple clinical trials of buprenorphine for opioid dependence. Part of the CTN's mission is to promote the adoption of evidence-based treatment technologies. Drawing on a data collected during face-to-face interviews with administrators from a panel of 206 CTPs, this research examines the adoption of buprenorphine over a 2-year period. These data indicated that the adoption of buprenorphine doubled between the baseline and 24-month follow-up interviews. Involvement in a buprenorphine protocol continued to be a strong predictor of adoption at the 2-year follow-up, although adoption of buprenorphine tripled among those CTPs without buprenorphine-specific protocol experience. For-profit CTPs and those offering inpatient detoxification services were more likely to adopt buprenorphine over time. A small percentage of programs discontinued using buprenorphine. These findings point to the dynamic nature of service delivery in community-based addiction treatment and the continued need for longitudinal studies of organizational change.
Radiation Interrogation Using Signature Analysis for Detection of Chemical Explosives

A signature-based radiation technique for detecting chemical explosive is described. Radiation techniques offer the advantage that they can operate at standoff, although rapid detection of explosives at safe standoff distances remains problematic. The technique we describe differs from the major nuclear approaches, which involve imaging (using either photon or neutron interrogation) and/or quantitative analysis (for instance by use of prompt-and inelastic-scatter gamma-ray production based on neutron interrogation). Our technique utilizes both photon and neutron interrogation but avoids imaging or quantitative analysis. The technique, which we call signature-based radiation scanning (SBRS), limits itself to detecting whether a target contains an explosive and does not attempt to characterize the internals of a target further. A template-matching technique is employed, which provides a single figure-of-merit whose value is used to distinguish between safe targets and those containing explosives. Both simulation and experiment have been used to verify the validity of SBRS.

Factors Influencing Pressure Ulcer Healing in Adults Over 50: An Exploratory Study

Objective The purpose of this study was to determine which demographic, clinical, and treatment factors influenced chronic pressure ulcer healing, and to identify the implications for pressure ulcer care being delivered in skilled nursing facilities. Design A multisite retrospective chart review was conducted using a structured data abstraction form and protocol. Setting Data collection took place in 3 geographically disperse areas of the country, with subjects having received wound care in hospitals, clinics, nursing homes, and home care. Participants Subjects whose charts were reviewed were 50 years of age or older, had at least 1 diagnosed chronic pressure ulcer, and had 3 to 6 months of data available for abstraction. Stage I ulcers were excluded from the analysis. Measures The structured data collection form included demographics, clinical variables, wound characteristics, and outcomes. The variables ulcer size, exudate type and amount, and necrotic tissue type were combined into a single wound severity score. Results Bivariate analyses showed that insurance type, secondary diagnoses of cardiovascular disease and pulmonary disease, initial ulcer size and stage, dressing type changes, use of topical antiseptics, type of debridement, category of dressing, use of hydrocolloid or wet-to-dry dressings, antibiotic administration, and appropriateness of selected dressing and management of necrosis were all significantly associated with healing within 6 months. Logistic regression models identified the following as the most significant predictors of healing: Medicaid, secondary diagnosis of cardiovascular disease, dressing type changed, topical antiseptics, antibiotic administration, pressure relief device, lack of exudate management dressing for moderate or large exudate wound, and lack of debridement of wounds with yellow slough, all decreased the odds of healing; use of exudate management dressings on wounds with no documented exudate increased the odds of healing. Conclusion Pressure ulcer healing rates overall could be improved if clinicians better matched the characteristics of the wound with the decision to debride and the selection of the optimal dressing. Healing within nursing homes might be improved with less use of enzymatic debridement and antibiotics and more frequent application of hydrocolloid dressings.
Anaerobic Degradation of Aromatic Compounds

The benzene ring moiety is found in biological compounds accounting for ~25% of the land-based organic matter on Earth. Hence, the biosynthesis and biodegradation of aromatic ring compounds constitutes an important part of natural carbon cycle. Microorganisms capable of using aromatic compounds as carbon and energy sources can be found in a range of very different habitats and redox conditions. In anoxic ecosystems where dissolved oxygen is depleted, degradation of aromatic compounds depends on the availability of inorganic electron acceptors such as nitrate, iron, sulfate or carbon dioxide. Developing efficient and effective bioremediation technologies requires an in-depth understanding of the microbial communities responsible for degradation of contaminants. Anaerobic microorganisms use a strategy of attacking the aromatic ring via reductive transformations. Anaerobic degradation of aromatic compounds (e.g. benzene, toluene and xylene (BTX), lignoaromatics, polycyclic aromatic hydrocarbons (PAHs) and halogenated aromatic compounds) has now been demonstrated under different redox conditions. One of the fundamental challenges has been to elucidate the microorganism(s) responsible for degradation of aromatic compounds in anaerobic environments. The recent advancements in molecular techniques have provided an opportunity to unravel the veil of the microbial activity responsible for the anaerobic degradation of aromatic compounds. This chapter provides an overview of some techniques and approaches to elucidate anaerobic degradation of aromatic compounds and how the active microorganisms can be identified, classified and enumerated.
Q-Switching of Semiconductor Lasers with Picosecond Light Pulses

Data supporting beta-amyloid dimer structural transitions and protein–lipid interactions on asymmetric lipid bilayer surfaces using MD simulations on experimentally derived NMR protein structures

This data article supports the research article entitled "Maximally Asymmetric Transbilayer Distribution of Anionic Lipids Alters the Structure and interaction with Lipids of an Amyloidogenic Protein Dimer Bound to the Membrane Surface" [1]. We describe supporting data on the binding kinetics, time evolution of secondary structure, and residue-contact maps of a surface-absorbed beta-amyloid dimer protein on different membrane surfaces. We further demonstrate the sorting of annular and non-annular regions of the protein/lipid bilayer simulation systems, and the correlation of lipid-number mismatch and surface area per lipid mismatch of asymmetric lipid membranes.
Reliability analysis of a parallel system with exponential life times and phase type repairs

We consider a parallel system consisting ofn identical components subject to failures. Failed components are repaired by a single repairman. Under the assumptions that the failure times are exponential and the repair times are of phase type, it is shown that the busy period of the repairman, the density of the number of components repaired during a busy period and the stationary down time of the system are also of phase type. Some numerical examples and an algorithmically tractable steady state analysis of the model are presented. Wir betrachten ein Parallelsystem ausn identischen fehleranfalligen Komponenten. Ausgefallene Komponenten werden in einem Reparaturkanal repariert. Unter der Annahme, daβ die Lebensdauern exponentialverteilt sind und die Reparaturdauern eine Verteilung vom Phasentyp besitzen, zeigen wir: Die Verteilung der Beschaftigungsperiode im Reparaturkanal, der Anzahl der wahrend der Beschaftigungsperiode reparierten Komponenten und der stationaren Ausfallzeit des Systems sind ebenfalls vom Phasentyp. Wir geben eine auch algorithmisch brauchbare Analyse des stationaren Verhaltens Modells und berichten uber einige numerische Ergebnisse.
WIND-GENERATED LONGSHORE CURRENTS

This paper evaluates, through the use of a stepwise multiple regression procedure, whether parameters descriptive of the surf-zone wave field adequately explain the variability in longshore current velocities, or if the inclusion of additional physical environmental parameters could significantly improve the ability to predict such currents. The data set consists of 250 LEO - observations, collected on a seasonal basis over one year, at Debidue Island beach, South Carolina. A regression analysis was performed both on linear combinations of all measured wave parameters, and on nonlinear parameter combinations proposed in various semiempirical predictive equations. Invariably, in all the regression analyses, the longshore component of the wind velocity proved to be the independent variable explaining most of the observed variance in the current velocity. Therefore, the statistical data analysis presented in this paper strongly suggests that wind stress can be a most significant factor in surf-zone current generation.
Reduced intestinal motility, mucosal barrier function, and inflammation in aged monkeys

We aimed to examine the general health and intestinal physiology of young and old non-human primates with comparable life histories and dietary environments. Vervet monkeys (Chlorcebus aethiops sabaeus) in stable and comparable social and nutritional environments were selected for evaluation. Health phenotype, circulating cytokines and biomarkers of microbial translocation (MT) were measured (n=26-44). Subsets of monkeys additionally had their intestinal motility, intestinal permeability, and fecal microbiomes characterized. These outcomes document age-related intestinal changes present in the absence of nutritional stressors, which are all known to affect gastrointestinal motility, microbiome, and MT. We found that old monkeys have greater systemic inflammation and poor intestinal barrier function as compared to young monkeys. Old monkeys have dramatically reduced intestinal motility, and all changes in motility and MT are present without large differences in fecal microbiomes. We conclude that deteriorating intestinal function is a feature of normal aging and could represent the source of inflammatory burden yet to be explained by disease or diet in normal aging human primate populations. Intestinal changes were seen independent of dietary influences and aging within a consistent environment appears to avoid major microbiome shifts. Our data suggests interventions to promote intestinal motility and mucosal barrier function have the potential to support better health with aging.
Provably Correct Persistent Surveillance for Unmanned Aerial Vehicles Subject to Charging Constraints

In this work, we present a novel method for automating persistent surveillance missions involving multiple vehicles. Automata-based techniques were used to generate collision-free motion plans for a team of vehicles to satisfy a temporal logic specification. Vector fields were created for use with a differential flatness-based controller, allowing vehicle flight and deployment to be fully automated according to the motion plans. The use of charging platforms with the vehicles allows for truly persistent missions. Experiments were performed with two quadrotors over 50 runs to validate the theoretical results.
A comprehensive model of clinical decision making.

Background Accountability in health care delivery requires that the ratio of patient benefits to patient costs be maximized. This goal is achieved by optimizing patient outcomes, expressed in terms of the degree to which discomfort and dysfunction are alleviated. To achieve this goal it is necessary to understand how diagnostic problem solving and clinical decision making under conditions of uncertainty are best carried out. Methods This paper synthesizes several studies of clinical problem solving and decision making into a coherent and comprehensive descriptive model. Results/conclusions This model should serve as a framework within which the more specific quantitative techniques necessary for optimizing patient outcomes can be developed. The ongoing development of such a model has profound implications not only for clinical practice but also for the education of clinicians and for clinical research.
Non-tracking organic insulations and their application to electrical apparatus

The susceptibility to carbon tracking upon exposure to electrical arcs has always been a fundamental weakness of organic insulations. Although recent emphasis has teen on the development of organic materials with more versatile physical characteristics and improved high-temperature properties, comparatively little work has been published on compounding materials to specifically resist tracking under severe electrical arcing conditions. When electrical apparatus is exposed to moisture, salt fog or dust, leakage currents result which produce electrical arcing on the exposed surface of the insulation. Under severe conditions most organic materials will develop carbonized surface tracks and even porcelain insulators will crack and chip from thermal shock.
Contemporary Water Use and Wastewater Generation

Knowledge of contemporary water use and wastewater generation is needed as a basis for engineering design of decentralized infrastructure. It is also needed to understand the benefits of water use efficiency and source separation as well as identify opportunities for recycling and reuse of reclaimed water. This chapter presents the characteristics of contemporary water use and wastewater generation in buildings within the United States and similar countries including residential (e.g., houses and other dwelling units) and nonresidential sources (e.g., commercial, institutional and recreational buildings and developments). Approaches for predicting contemporary water use and wastewater generation data are described.
The Study of Motivation

Motivational design, the central topic of this book, provides a bridge between the study of motivation and the practice of enhancing or modifying people’s motivation. On one side of the bridge are concepts, theories, and principles resulting from the study of human motivation, and on the other side are procedures, successful practices, and design processes that have resulted from the work of designers and practitioners whose aim is to improve learner motivation. Frequently, this bridge is represented as being one way as in the expression, “from theory to practice,” which suggests that scientists discover basic principles and practitioners apply them. However, the process is not nearly so linear; that is, it is not possible to prescribe a direct application to practice for every motivational principle that has been empirically supported, and not every successful practice can be explained by a particular motivational concept. Thus, the bridge is two way. Designers and practitioners learn from the work of researchers and create ways of incorporating that knowledge in practice, and researchers can learn from observing relationships in contexts of application which then provide a basis for theorizing and testing. A primary purpose of this book is to bring the two sides of the bridge together. Even though there are many individuals who have specific motivational talents and there is an enormous amount of research on human motivation, there has been little systematic guidance for those who are trying to learn how to be more predictably effective in motivating their learners. A primary purpose of this book is to provide such guidance in the form of a motivational design process; that is, it consists of a general model of design that is grounded in motivational theory but also incorporates systematic audience analysis based on the primary components of human motivation to diagnose specific motivational problems that exist in a given situation. Then, the results of this analysis lead to the design and/or selection of motivational strategies that are compatible with the learners, instructors, and learning environment.
Cognitive and Motivational Effects of Animated Pedagogical Agent for Learning English as a Second Language

This paper discusses the results of a pilot study that explores the cognitive and motivational effects of an animated pedagogical agent as well as an alternative delivery system (a simple flashing arrow with audio) in a multimedia environment in which college level ESL students learn English relative clauses. The study also examines the cognitive efficiency of these two media systems used to deliver the same instructional method for teaching English grammar.
La Organización Internacional del Trabajo y la libertad sindical en América Latina: el caso de Venezuela en 1949.

This article analyzes the relationship between the International Labor Organization (ILO) and the trade union movement in Latin America. If attempts to strengthen the workers' movement were long-standing, during the 1930s relations between the Latin American trade union movement and the ILO began to become more regular, especially in international forums. Special attention deserves the assistance mission carried out by the ILO in Venezuela in 1949 to study the situation of workers' organizations after the establishment of the military dictatorship of General Carlos Delgado (1948). Document relevant is the report written by the mission led by Jef Rens, Assistant Director General of the ILO, and published in 1949.

Modelling and analysing a class of flexible manufacturing system

In this paper, a special algebraic structure called path algebra or max-algebra is used for modelling and analysing nxm flexible manufacturing system (FMS) in which m jobs are processed on n machines. The pseudo-linear system model with finite buffer is established. The modelling allows for evaluating the dynamic behavior of the system under a deterministic and cyclic production process. Given any fixed processing time and routing of processing activities, the steady-state running rhythm of the system can be determined from eigenvalue of the system, i.e., the average weight of critical circuit of closed-loop network. Some results about the dynamic behavior of nxm flow-shop and job-shop FMS and illustrative examples are given.
Intergenerational mobility and the political economy of immigration

Abstract Flows of US immigrants are concentrated at the extremes of the skill distribution. We develop a dynamic political economy model consistent with this observation. Individuals care about wages and the welfare of their children. Skill types are complementary in production. Voter support for immigration requires that the children of median-voter natives and of immigrants have sufficiently dissimilar skills. We estimate intergenerational transition matrices for skills, as measured by education, and find support for immigration at high and low skills, but not in the middle. In a version with guest worker programs, voters prefer high-skilled immigrants but low-skilled guest workers.
Multiorgan system structural malformations associated with Mayer-Rokitansky-Küster-Hauser Syndrome (MRKHS) type 2: avoiding pitfalls in diagnosis, counseling and treatment.

An 18-year-old virginal woman was referred to the reproductive endocrinology clinic with primary amenorrhoea and secondary sexual development in the absence of pelvic pain. Additionally, she had significant congenital sensorineural hearing loss, autism, bipolar disorder and class III obesity. On physical examination, secondary sexual development was confirmed (Tanner 5 breasts and Tanner 4 pubic hair). She refused further pelvic examination following prior attempts by the referring physicians. Serum leutinizing hormone (LH), follicle sitmulating hormone (FSH). prolactin, estradiol and total testosterone values were within normal limits. Karyotype was 46,XX. MRI demonstrated complete uterine agenesis, short vagina, sacral dysgenesis with complete absence of the coccyx and a horseshoe kidney. Diagnosis of Mayer-Rokitansky-Kuster-Hauser Syndrome type 2 was established based on clinical, laboratory and MRI findings. The patient and family were counselled regarding the disease process, techniques for vaginal elongation, sexual activity and future reproductive options.
Treadmill stress tests should not be part of "routine health check package"

A treadmill ECG stress test (TMT) often forms part of the popular health check packages recommended for people who are asymptomatic on the premise that it can detect disease at an early stage and treatment be prescribed to prevent or reduce future morbidity and mortality. Such a recommendation does not take into account the properties of this procedure as a diagnostic test. It has an average sensitivity and specificity of 68% and 77%, respectively. However, these figures depend on the probability of coronary artery disease (CAD) in the test subject. In asymptomatic persons with few or no risk factors, the likelihood of a false positive is high and will result in psychological stress and/or expensive and possibly invasive test. Recommendation for a TMT should be made by a physician after evaluating the subject to have at least an intermediate risk of having CAD.

Interference, spectral momentum correlations, entanglement, and Bell inequality for a trapped interacting ultracold atomic dimer: Analogies with biphoton interferometry

Aiming at elucidating similarities and differences between quantum-optics biphoton interference phenomena and the quantum physics of quasi-one-dimensional double-well optically trapped ultracold neutral bosonic or fermionic atoms, we show that the analog of the optical biphoton joint-coincidence spectral correlations, studied with massless noninteracting biphotons emanating from Einstein-Podolsky-Rosen Bell-Bohm single-occupancy sources, corresponds to a distinct contribution in the total second-order momentum correlations of the massive, interacting, and time-evolving ultracold atoms. This single-occupancy contribution can be extracted from the total second-order momentum correlation function measured in time-of-flight experiments, which for the trapped atomic system contains, in general, a double-occupancy, NOON component. The dynamics of the two-particle system are modeled by a Hubbard Hamiltonian. The general form of this partial coincidence spectrum is a cosine-square quantum beating dependent on the difference of the momenta of the two particles, while the corresponding coincidence probability proper, familiar from its role in describing the Hong-Ou-Mandel coincidence dip of overlapping photons, results from an integration over the particle momenta. Because the second-order momentum correlations are mirrored in the time-of-flight spectra in space, our theoretical findings provide impetus for time-of-flight experimental protocols for emulating with (massive) ultracold atoms venerable optical interferometries that use two space-time separated and entangled (massless) photons or double-slit optical sources. The implementation of such developments will facilitate testing of fundamental aspects and enable applications of quantum physics with trapped massive ultracold atoms, that is, investigations of nonlocality and violation of Bell inequalities, entanglement, and quantum information science.
Familial patterns of expression of specific reading disability in a population sample

A sample school population of 75 family units of equal size was investigated for expression of specific reading disability. 25.3% of the total children showed specific reading disability as defined in this study. By using spelling achievement as the criterion for the presence of the disability, the incidence of the disorder was shown to be much higher in certain families than in others, with clear sibling aggregation. The siblings of specific-reading-disability cases demonstrated lower spelling competence than the total siblings in normal families, even when well above a crippling level. Both within individual families and by grades, the spelling rating in relation to grade norms of the specific-reading-disability family cases with their siblings tended to decline with age, in contrast to normal families where it tended to improve with age. This pattern was even more striking if the greater language competence of females, now quite generally accepted and further supported by this study, was taken into account. It was demonstrated that the above patterns were not primarily a product of intelligence level or teaching methods. The bearing of these findings on the tenability of the most common, current hypotheses concerning causation was briefly discussed.
Big Ten Basketball, 1943 – 1972, by Murry R. Nelson

The NCAA reported that it had a total revenue of $1.045 billion from basketball in 2017. Also, in 2017, the Big Ten conference reported that it made profits of about $93 million on men’s basketball...
Active Trading and (Poor) Performance : The Social Transmission Channel

Active investors often generate inferior returns. Social interactions might exacerbate this tendency, but the causal link between peer effects and active trading is difficult to identify empirically. This paper exploits the exogenous assignment of students to classrooms in a large-scale financial education initiative to evaluate the transmission of trading strategies among individual investors. The paper shows that students assigned to groups where classmates have more trading background, are more likely to start trading after completing the program. These social effects are stronger when peers have experienced favorable outcomes. The paper documents a negative consequence from social interactions: students that registered for courses where peer returns are large, generate lower trading profits than other investors. The evidence is consistent with social learning under biased information -- people share their most successful experiences, encouraging stock trading among uninformed investors. The results shed light on the role of selective communication in the transmission and adoption of ideas, and more importantly, in the behavior of people expose to biased information. The findings show that social learning can lead to misguided decisions when peer choices are not accurately observed by members of the social network.
In the General's Valley: China, Africa, and the Limits of Developmental Pragmatism

Since the turn of the millennium, the landscape of development in Africa has undergone a dramatic shift. China has significantly expanded its foreign aid and investment in the region, decentering the West as Africa9s main development partner. What is largely missing from China-Africa scholarship, however, is attention to how the new Chinese presence in Africa is both embedded in and altering everyday social relations. This article examines these issues in a rural setting in Uganda that is in the midst of a large-scale transformation into a China-funded industrial park. It reveals that the complex new politics of Chinese development assistance are intertwined with, and often exacerbate, existing social inequalities based in politics, class, ethnicity, and race. More conceptually, these dynamics demonstrate the need to rethink how we frame development as a transnational field of social practice. China is more than an outlier within the global field of development and instead should be viewed as pursuing its own form of development, what I call “developmental pragmatism.” As this case study illustrates, this developmental pragmatism often turns on synergies between the business-focused development approach of the Chinese and the priorities of more authoritarian governments—synergies that require much greater critical attention.
Palladium-Catalyzed Asymmetric Allylic Fluoroalkylation/Trifluoromethylation

The first palladium-catalyzed asymmetric allylic trifluoromethylation is disclosed. The methodology evokes a fundamental principle by which the synergistic interplay of a leaving group and its subsequent activation of the nucleophilic trifluoromethyl group enabled the reaction. Allyl fluorides have been shown to be superior precursors for generation of π-allyl complexes, which lead to trifluoromethylated products with high selectivities and functional group tolerance. This study highlights the unique role of a bidentate diamidophosphite ligand class in palladium-catalyzed reactions that allow a challenging transformation to proceed.
