An Exact Calculation for a T-Junction of Rectangular Waveguides Having Arbitrary Cross Sections

An exact method is developed for the calculation of the electrical performance of the rectangular waveguide T-junction. This method is used to find the equivalent circuit of a rectangular waveguide T-junction in which both cross-sectional dimensions of the side waveguide are different from the cross-sectional dimensions of the through waveguide. The theoretical calculations for a particular T-junction of this type are verified by experimental measurements. In this method the electrical performance is analyzed by using equivalent-circuit concepts applied to waveguide modes to calculate an admittance matrix relating propagating and cutoff waveguide modes to each other. Then the cutoff modes are terminated in their characteristic impedance, and an equivalent admittance matrix of the junction is found relating only the propagating modes in each waveguide to each other. The anlysis is valid when any number of modes can propogate in the waveguides forming the junction. The Inversion of an infinite matrix is required; however, any desired accuracy can be obtained by considering a matrix of finite but sufficient size or equivalently by considering a sufficient number of cutoff modes.
Joint Effect of Endothelial Dysfunction and New-onset Diabetes Mellitus in Predicting Cardiovascular Outcomes in Hypertensive Patients: a Cohort Study

Background. Endothelial dysfunction, induced by some cardiovascular risk factors, is the early determinant of atherosclerotic cardiovascular disease. Moreover, it predicts incident type-2 diabetes that is associated with an increased risk of fatal and nonfatal cardiovascular events; however, no data demonstrating a possible interaction between them in predicting cardiovascular outcomes are available. Thus, we designed present study to evaluate the prognostic significance of the joint effect of endothelial dysfunction and new-onset type-2 diabetes in hypertensives.Methods. We enrolled 653 white never-treated hypertensive outpatients free of cardiovascular events from the CATanzaro Metabolic Risk factors (CATAMERI) study. All subjects were without type-2 diabetes, heart failure and chronic kidney disease. Endothelium-dependent vasodilation was investigated by intra-arterial infusion of acetylcholine, and laboratory determinations were obtained by standard procedures. Follow-up included periodic control visits every six months in our out-patients Clinic and ranged from 26-206 months (median 113). Patients were treated to reduce blood pressure <140/90 mmHg using standard lifestyle and pharmacological treatment. Incident type-2 diabetes and following cardiovascular events were monitored: fatal and nonfatal myocardial infarction and stroke, TIA, unstable angina, coronary revascularization procedures and symptomatic aortoiliac occlusive disease.Results. We documented 191 new cardiovascular morbid events (3.1%) at the cardiac (n=134), cerebrovascular (n=50), or peripheral (n=7) level. Dividing the study population in progressors and non-progressors, progressors were older and had a higher baseline heart rate, fasting insulin, HOMA, creatinine, and hs-CRP mean values, while e-GFR and acetylcholine-stimulated forearm blood flow (FBF) were lower. Similarly, incident type-2 diabetes was higher in the progressors group. In the multiple Cox regression analysis, incident diabetes (HR=2.015, 95%CI=1.416-2.868), hs-CRP (HR=1.306, 95%CI=1.213-1.407) and acetylcholine-stimulated FBF (HR=0.729, 95%CI=0.633-0.839) maintained an independent association with the outcomes. The interaction between new-onset diabetes and FBF demonstrated that patients with new diabetes and maximal FBF under the median show a higher risk for subsequent cardiovascular events (HR=7.411, 95%CI=4.875-11.265). Conclusions. Endothelial dysfunction and new-onset diabetes predict cardiovascular events and their joint effect greatly increases this risk. These results highlight the importance of interaction between hemodynamic and metabolic alterations in predicting cardiovascular events.
Influence of Cable Layout on the Performance of ITER-type Nb3Sn Conductors

In 2005-2006, the European Union tested in the SULTAN facility (CRPP Villigen, Switzerland) four ITER-type conductors assembled in two samples. Each conductor made use of an advanced Nb3Sn strand specially developed by European companies for the ITER Toroidal Field (TF) coil conductor. The cable layout of these conductors was the one of the ITER TF Model Coil conductor. In 2007, the European Union tested in SULTAN four other conductors within two other samples as prototypes of the updated ITER TF conductor. These conductors differed mainly from the former by their cable layout whereas identical or similar Nb3Sn strands were used. The paper reports on the current sharing temperature measurements of the second samples under ITER relevant operating conditions. The effect of cycling (1000 cycles) in current under full magnetic field was also investigated. The analysis of the test results is performed with respect to the strand properties using the usual smeared models of the cable. These test results were found to be significantly better than those obtained on the first conductors. The paper discusses the possible causes as well as the consequences of such a performance scattering.
TRANSFER EFFECT OF N-BACK TRAINING: MATHEMATICAL IMPLICATIONS IN SCHOOL-AGE CHILDREN

Working memory (WM) is the system which is used for short-term storage and where information about cognitive tasks is manipulated. One of the most important characteristics of WM is its limited capacity, which restricts cognitive performance. Despite of this limit in WM capacity, the efficiency of WM can be improved with WM training and this training effect can be transferred to performance on complex tasks, such as mathematical operations. Such training tasks are complex and necessarily include core processes and these measures, therefore, contribute to difficulty to design tasks and interpret the outcomes for specific changes gained from the training. For example, n-back tasks which are used in a wide range of research are based on core training. Since core trainings address the executive functions of WM and enhance the domain-general aspects, increasing performance on domain-general factors may promote both near and far transfer effects of training. In the current study, WM training will be constructed on the basis of the interference framework that characterizes individual differences in WM performance. The aim of this study is to explore individual differences in training and the way transfer effects occur, evaluating gains from Mathematics proficiency. An adaptive version of n-back tasks will be implemented for the proposed study, within WM load and interference lures. The study will be carried out with 40 school-age children between the ages of 9 and 12, and Solomon four group design method will be used to group them. d’ (D-Prime) theory will be conducted in order to obtain detailed comparison between groups as well as interpretation of individual differences in processing of information.
Field Pea (Pisum sativum L.) Variety Development for Moisture Deficit Areas of Eastern Amhara, Ethiopia

Twelve field pea genotypes were evaluated in seven environments in Eastern Amhara in main production season (2010-2012). The objective of this trial was to identify stable and high yielding field pea genotype for production in Eastern Amhara. The trial was conducted using randomized complete block design with three replications. Combined analysis of variance for grain yield revealed that genotypes, environments, and genotype by environment interaction effect were highly significant (P ≤ 0.01). The environments, GEI, and genotypes were accounted for 77.47%, 13.83%, and 4.37%, of the total sum squares, respectively, indicating that field pea grain yield was significantly affected by the changes in the environment, followed by GEI and genotypic effect. The candidate genotype, EH-03-002, showed 14.42% and 44.87% yield advantage over the standard and local checks, respectively. Considering the seven environments data and field performance evaluation during the variety verification trial, the National Variety Releasing Committee has approved the official release of EH-03-002 with the vernacular name of “Yewaginesh” for moisture deficit areas of Wag Lasta and similar agroecologies.
On the Action of Wetting Agents in the Extinction of Wood Fires

A RECENT ARTICLE by Pasek and McIntyre [1] presents Arrhenius parameters for the oxidation of Southern Pine wood samples both untreated and treated with various fire retardants. The pre-exponential factor A (2 x 105 s-1) and activation energy E (88 kJ mol-’) of the untreated sample are both within the range of values recently reported by the present group of various samples of forest litter [2,3] from areas comprising chiefly Eucalyptus species. Work has continued on materials derived from Eucalyptus trees, and in this note we furnish results relevant to a matter connected with the retardation of wood fires: the extinction of a wood fire having already begun. Wetting agents added to water are commonly used in the fighting of forest fires, and this note deals with the efficacy of three examples of such agents.
Granular Overlays on Low-Volume Roads in Washington State: Structural and Performance Characteristics

The granular overlay system is an alternative type of overlay for rehabilitating mostly low-volume, rural pavements. The overlay consists of a layer of densely compacted, crushed stone overlaid by a generally thin surface layer (either a bituminous surface treatment or asphalt concrete). The Washington State Department of Transportation continues to be interested in these roadways because performance has been better than expected with rehabilitation survival lives doubling from 7 to 14 years with the addition of granular overlays. Previous attempts to backcalculate layer moduli and understand the structural characteristics of granular overlays were limited because of uncertainties associated with layer thicknesses. With known layer thicknesses obtained from four sites, backcalculation of granular overlay pavements was possible. These moduli along with straightforward performance information are used to characterize granular overlays.
Investigation of Conditions for Moisture Damage in Asphalt Concrete and Appropriate Laboratory Test Methods

Moisture damage is the progressive deterioration of asphalt mixes by loss of adhesion between asphalt binder and aggregate surface and/or loss of cohesion within the binder due to water. It is a complex phenomenon affected by a variety of factors, and has not been fully understood in the pavement community with major knowledge gaps in three areas: major contributing factors to moisture damage in the field, appropriate laboratory test procedures, and the effectiveness of treatments. Both field investigation and laboratory investigation were performed in this study to fill up some of the major gaps. Statewide condition survey and field sampling were conducted to identify factors contributing to moisture damage. Statistical analysis revealed that air-void content, mix type, pavement structure, cumulative rainfall, and pavement age significantly affect the extent of moisture damage. Laboratory experiments revealed that high air-void contents not only allow more moisture to enter mixes, but also significantly reduce the fatigue resistance of mixes wet conditions. Reduction in the binder content from the optimum binder content may significantly reduce the moisture resistance of asphalt mixes under repeated loading. The effectiveness of Hamburg wheel tracking device (HWTD) test to determine moisture sensitivity of asphalt mixes was evaluated by both laboratory prepared specimens and field cores. Results revealed that the current test procedure does not clearly distinguish mixes with different moisture sensitivities. The test tends to overestimate the performance of mixes containing conventional binders and underestimate the performance of mixes containing polymer modified binders. Several ways to improve the prediction accuracy of the HWTD test were suggested. As a new approach of testing, a fatigue based test procedure for evaluating moisture sensitivity was explored in this study. A typical test procedure was determined for comparative evaluation of different mixes, which is a controlled-strain flexural beam fatigue test performed at 20Â°C, 10 Hz and 200I¼Iµ on specimens pre-saturated under 635 mm-Hg vacuum for 30 minutes and preconditioned at 60Â°C for one day. An extension of the test procedure for use in the pavement design was also discussed. The long-term effectiveness of both hydrated lime and liquid antistripping agents in improving the moisture resistance of asphalt mixes was evaluated by both the tensile strength ratio (TSR) test and the fatigue beam test. Results showed that both treatments are effective even after one yearâ€™s moisture conditioning.
Results of indoor propagation measurement campaign for WLAN systems operating in 2.4 GHz ISM band

The indoor measurement campaign in the 2.45 GHz ISM frequency band was described. Two types of measurements and data processing - narrowband and wideband - were presented. The empirical parameters for standard indoor propagation models were derived. Time variations of WLAN signal level were investigated and the cumulative distribution functions based on log-normal distribution were determined. The position as well as the azimuthal orientation of the measurement notebook was considered. Using the results, the indoor coverage planning of WLAN systems is possible including the prediction of link availability and overall QoS. In addition, the measured data can be further used for angle diversity studies.

Single-Loop Project Controls: Reigning Paradigms or Straitjackets?

This article reports on the results from an ongoing research program to study the role mental models play in project decision making. Project management belongs to the class of multiloop nonlinear feedback systems, but most managers do not see it that way. Our experimental results suggest that managers adopt simplistic single-loop views of causality, ignore multiple feedback interactions, and are insensitive to nonlinearities. Specifically, the article examines single-loop models of project planning and control, discusses their limitations, and proposes tools to address them.
Impatiens damingensis (Balsaminaceae), a new species from Guangxi, China

Impatiens damingensis S. X. Yu, C. Y. Xia & H. P. Deng, (Balsaminaceae) discovered in Guangxi, China, is described and illustrated here. This species is similar to I. aquatilis Hook.f. , but differs from the latter by having blades that are ovate or ovate-lanceolate vs. lanceolate, ovate-lanceolate, or ovate-oblong; apices of bracts acute vs. glandular awned; apices of lateral sepals mucronulate vs. long mucronulate; and spur slender substraight or slightly incurved vs. incurved. Furthermore, molecular data as well as micro-morphological evidence under SEM (of pollens and seeds) also support the establishment of the new species.
Field excitation of complex multiconductor cable bundles-simulations and measurements

Starting from an existing computer code based on an extended transmission line theory a software has been developed which allows to calculate the interaction between incident electromagnetic fields and comparatively complex cable bundles consisting of different cable types whereby arbitrary shielded multiconductor transmission lines can be considered. Up to now single shielded lines have been simulated. This paper shows results obtained by simulations and measurements in a GTEM cell for complex cable bundles consisting of unshielded and shielded transmission lines, single conductors and coaxial cables. Simulation and measurement results will be compared and discussed.
Prevalence of Diagnosed Celiac Disease and Associated
Conditions in the United States between 2012-2017: Results
from a National Electronic Patient Database

Background: Celiac Disease (CD) is an autoimmune condition caused by the ingestion of gluten in genetically susceptible individuals. Previous screening studies of CD have shown wide-ranging prevalence estimates. We sought to describe the prevalence of diagnosed CD in the United States (US) using a large, electronic, population-based database, and identify associated conditions of interest. Methods: From a large commercial database (Explorys), we identified a cohort of patients with CD between April 2012 and April 2017, based on Systematized Nomenclature of Medicine-Clinical Terms (SNOMED-CT). From this cohort, we calculated the prevalence of CD and were able to identify associations between CD cases and other conditions. Results: Of the 35,854,260 individuals in the database, we identified 83,090 cases of CD, with an overall prevalence of 231.7/100,000 persons (0.23%). Prevalence was higher in females than males [odds ratio (OR) 2.40; 95% Confidence Interval (CI) 2.36-2.43, p < 0.0001], whites versus non-whites (OR 2.25; 95% CI 2.20-2.30, p < 0.0001) and adults (≥ 18 years) versus children (< 18) (OR) 2.60; 95% CI 2.53-2.67, p < 0.0001). CD was found to be associated with many other medical conditions. Conclusions: In this large study, we found that the estimated prevalence of diagnosed CD in the USA is considerably lower than previous screening estimates, suggesting a large burden of undiagnosed CD. We were also able to identify strong associations between CD and many other medical conditions.
Characterizing The Unconfined Ceiling Jet Under Steady-state Conditions: A Reassessment

Detailed velocity and temperature measurements using cross-correlation velocimetry were obtained for unconfined ceiling jets under ceiling transient and steady-state conditions. Small fires of 0.5 to 2.0 kW were produced with a premixed methane-air burner. These measurements represent one of the most detailed studies of unconfined ceil ing jets to date and seem to be in general agreement with large-scale data. Empirical correlations for the steady-state ceiling jet temperature and velocity profiles are described herein. The correlations compare well with, and have improved, results from previous works. The maxi mum temperature may not be scaled as a function of fire-to-ceiling heights for large radial distances. Furthermore, the Gaussian and boundary layer thermal and momentum thicknesses of the ceil ing jet are not equal, contrary to the assumptions made in other works.
Factors that Influence Students' Choice of Careers in Construction Management

The goal of this study was to explore the demographics and career influences (in terms of experiences and relationships) of students currently enrolled in accredited Construction Management (CM) programs in one Midwestern state. It was limited to one state due to the regional differences in construction shown by a 1996 Business Roundtable (BRT) study (The Business Roundtable, 2000). Numerous factors influence students who enter CM programs; however, insufficient information exists to explain the characteristics of these students. Obtaining a better understanding of students currently enrolled in construction management programs can reveal perceptions of the construction industry and can enlighten CM programs for future marketing. Three research questions were posited to four accredited CM programs in one Midwestern state. The survey yielded 504 completed and usable survey instruments. Frequency tables were produced to compare data by program and gender. Analysis of Variance (ANOVA) and chi-square analysis were performed as a test for significance of the variables. All students had some work experience; however, few reported technical and career training experiences in high school. Students reported that “hands-on type activities” and “interest in construction” were the major influences. The high school counselor was the least influential person with respect to students’ choice of careers in construction management.
Preparation of poly(acrylonitrile-co-methyl acrylate)/cellulose composite membranes and their application in wastewater treatment

Abstract In this study, new poly(acrylonitrile-co-methyl acrylate)/cellulose composite membranes were prepared firstly and then characterized. Then they were used in the removal of Fe(III) and Co(II) ions from wastewater with a stirred ultrafiltration cell. Also, alginic acid polymer was used as complexing agent to enhance the retention. In the filtration of Fe(III) and Co(II) solutions, the effects of pH, concentration of solutions, and pressure on the retention percentage were examined. Aqueous solutions of Fe(III) and Co(II) were filtrated at the stirred velocity of 400 rpm. The maximum retention percentage was found as 78.66% for Fe(III) solution at the pH of 3.3, concentration of 0.3 × 10−4 M Fe(III) solution, pressure of 40 psi by using 2.5 (w/v)% Poly(acrylonitrile-co-methyl acrylate)/cellulose composite membranes. For Co(II) solutions the maximum retention percentage was found as 77% at the pH of 6, concentration of 0.3 × 10−4 M Co(II) solution, pressure of 50 psi by using 2.5 (w/v)%Poly(acrylonitrile-co-methyl acrylate)/cellulose composite membranes.
Comparison of lipoprotein and apolipoprotein levels in cord blood

Background: Hyperlipidemia is the primary risk factor for coronary artery disease and subsequently leading to morbidity and mortality in adulthood. It is a well-known fact that coronary artery disease can initiate in the fetal stage itself. The present study was planned to analyse cord blood lipoproteins and apolipoproteins levels and its association with gender and birth weight.Methods: This cross-sectional study was conducted in the Department of Biochemistry, in collaboration with Department of Gynecology and Obstetrics at SKIMS Medical College and Hospital, Bemina, Srinagar. A total 200 pregnant women who delivered by normal vaginal delivery and caesarean section were included in the study. 10 ml of umbilical cord blood was collected in a plain vial from the placental end within five minutes of delivery and serum lipoprotein and Apo-lipoprotein levels were measured.Results: Out of 200 newborns102 were males and 98 were females. Statistically significant difference was seen in parameters Apo A1, Apo B, Atherogenic index (Apo B/Apo A1) and LDL between the genders rest of the parameters were statistically. Also 32 newborns (16.0%) had <2500, 152 (76.0%) new born had 2500-4000 and 16(8.0%) > 4000 grams birth weight. The mean lipoprotein and Apo-lipoprotein levels in these new born were compared between the groups. The mean serum levels of TC, TG, LDL and HDL were statistically significant (<0.05) between the three groups were as Apo A1, Apo B, Atherogenic index (Apo B/Apo A1) and VLDL was insignificant (>0.05) respectively.Conclusions: CVD being a leading cause of morbidity and mortality in the developing countries, early screening of the at risk babies i.e. low birth weight newborns using cord blood lipoproteins and apolipoproteins levels helps in primordial and primary prevention of diseases.
