Light-weight low-profile monopole array antenna with wideband circular polarization on flexible substrate

ABSTRACT A novel 2×2 broadband circularly polarized low-profile monopole array antenna adopting the sequential rotation technique is presented and experimentally studied in this article. The array is very lightweight and is printed on the 0.2 mm flexible substrate. The basal antenna element of the 2×2 arrays is a printed curve-shaped monopole with good bandwidth and circular polarization property. The simulated and measured impedance bandwidth and axial ratio bandwidth are presented. Moreover, radiation patterns are also presented. The advantages of the proposed antenna include low-profile, light-weight, simple structure, and broad working bandwidth.
Performance and Internal Organ Characteristics of Broiler Chickens Fed Red Sorghum (Sorghum bicolor L. (Moench)) Based Diets Supplemented with Complex Enzyme (Kingzyme®)

The study was designed to study the effect of complex enzyme (Kingzyme®) on performance and carcass yield of broiler chickens fed red sorghum-based diets. Two hundred (200) chicks (day-old) of mixed sex was randomly allotted to five dietary treatments (T1, T2, T3, T4 and T5) supplemented with enzyme complex (Kingzyme®) at the levels of 0.0g, 0.2g, 0.5g, 0.8g and 1.1g kg per Kg of feed respectively in a Completely Randomized Design (CRD). Each treatment was replicated four (4) times to contain ten (10) birds each. Feed and water were provided ad libitum accompanied with standard management procedures for eight weeks. At end of the experiments, eight (8) birds whose body weights are closest to the mean of the group was randomly selected from each treatment (two (2) per replicate) and was fasted overnight to reduce the gut contents and carcass contamination. The birds for each replicate was weighed to determine the live body weight, followed by slaughtering, bleeding, bled weight determination, scalding and wet plucking. The plucked weight was determined followed by evisceration, dressed weight and weighing of internal organs. The weight of the internal organs and length of small, large intestines and caecum was determined. The weights of the internal organ were expressed as the percentage of the dressed weight. Data were analyzed using Statitix Analytical Software, Version 10; and the treatment means were compared using Turkey HSD. There was no significant (P < 0.05) difference across the treatment groups for feed intake and growth performance at both starter and finisher phases respectively. Similarly, carcass characteristics showed no significant (P < 0.05) difference across the dietary treatments. Lungs, gizzard and proventriculus was significantly (P < 0.05) affected across the dietary treatments. Based on the result of the study, it was concluded that Red Sorghum-based diet supplemented with enzyme complex (Kingzyme®) do not have any significant effect on feed intake and growth performance of broiler chickens but can change some internal organs weights especially the lungs, gizzards and proventriculus.
The Madden‐Julian Oscillation in an Aquaplanet‐Like General Circulation Model With and Without Continents

We have conducted experiments with the Community Atmospheric Model version 5.1 configured as an aquaplanet, with the sun at March equinox, in order to study how the model Madden‐Julian oscillation (MJO) responds to (i) the introduction of continents and (ii) realistic sea surface temperature (SST) distribution. Model results are compared with ERA‐Interim reanalysis and analyzed in terms of the moist static energy (MSE) budget to study the growth and propagation of MJO. With idealized zonally symmetric SST, the aquaplanet model produces a double Intertropical Convergence Zone (ITCZ) and an MJO‐like mode with variance at intraseasonal (30‐ to 96‐day) periods and zonal wave number 1. When we introduce continents with realistic orography and interactive surface temperature, soil moisture, and albedo, the variance of MJO is mainly confined to zonal wave numbers 1 and 2 but reduced by a factor of 3 due to weaker boundary layer moisture convergence. With prescribed climatological January SST boundary condition (which includes Indo‐west Pacific warm pool) in the presence of continents, model MJO variance is enhanced and distributed across zonal wave numbers 1 to 5, in closer agreement with observation. Thus, the presence of land by itself is not enough, but realistic SST distribution is necessary for improved space‐time characteristics of model MJO. Both in simulations and ERA‐Interim data, meridional and vertical advection of MSE promotes eastward movement of MJO. In the model experiments, meridional advection of low‐level MSE anomaly is most significant in the vicinity of the ITCZ, indicating the importance of processes that determine the location of (single or double) ITCZ.
PPLPI's Livestock Development Goals: Application of LDG1 to Peru, Senegal and Viet Nam

Although the poor constitute a majority in developing countries, their circumstances vary in significant ways between and within their economies. To improve their livelihoods, a better understanding of this heterogeneity is essential. This report examines poverty from the perspective of livestock dependence, an essential characteristic of rural and peri-urban households in developing countries. We find that livestock dependent populations are more likely to be poor, but the degree of their poverty depends on complex local circumstances, including the extent of formal sector participation, property rights, and access to capital. Our insights suggest that more determined efforts to promote smallholder livestock production can be a potent catalyst for poverty alleviation, but that policies aimed at promotion of smallholder livestock keepers need to be carefully targeted and that although they can bring a large proportion of the poor over the poverty threshold, there are circumstances in which they will not reach the poorest population. Both poverty and livestock dependence are complex economic conditions, and policies must address this to be effective. More detailed insight into the economics of livestock can, however, make important contributions to poverty reduction. PPLPI Research Report 2
Effects of Virtual Reality Pilates Training on Duration of Posture Maintenance and Flow in Young, Healthy Individuals: Randomized Crossover Trial

Background This study explored the use of virtual reality (VR) technology to enhance the effectiveness and duration of low-intensity movements and postures in Pilates-derived exercises. We postulate that by leveraging the flow state in VR, individuals can engage in these exercises for longer periods while maintaining a high level of flow. Objective The purpose of this study was to compare differences in posture maintenance and flow between VR Pilates training and conventional Pilates training, and the correlation between the 2 factors. Methods The 18 participants in each group received either VR training or conventional training and were switched to the other training type after a 2-day wash-out period. Each group performed Pilates movements in a VR environment and a conventional environment, divided into 4 types. After training sessions, participants were evaluated for flow using a self-report questionnaire. In addition, a sports video analysis program was used to measure the duration of posture maintenance in 2 video-recorded sessions. Repeated-measures ANOVA and correlation analysis were performed on the measured duration of posture maintenance and flow scores. In all cases, the statistical significance level was set at P<. 05. Results Results for the duration of posture maintenance verification by type showed that simple behavior (F1,16=17.631; P<.001), upper body–arm coordination behavior (F1,16=6.083; P=.04), upper body–leg coordination behavior (F1,16=8.359; P<.001), and whole-body coordination behavior (F1,16=8.426; P<.001) all showed an interaction effect at P<. 05. Flow (F1,16=15.250; P<.001) also showed an interaction effect. In addition, significant correlations were determined between duration of all types of posture maintenance and flow in the VR training group at P<. 05. Conclusions Our results indicate that VR Pilates training may be more useful than conventional Pilates training in improving the duration of posture maintenance and that it promotes a significantly higher degree of flow when compared with conventional Pilates training.
Survival, regrowth and rubber production of clipped guayule plants: Effects of irrigation regime, season and line

Guayule (Parthenium argentatum A. Gray) plants of USDA lines 11604,12229 and 11591 were subjected to irrigation regimes of 300,450, and 650 mm/per year and clipped at different ages over a period of several years. Survival, regrowth rates, biomass production, and rubber and resin accumulation in the plants after cutting at ground level were monitored. A survival rate of 92-100% was recorded in plants clipped in February (end of the dormant period) or October (just before the dormant period). In plants cut in summer (July) survival was less and presumably dependent on plant water status and age. No significant differences were evident among the different lines. The best plant development as determined by rate of height increase occurred in plants clipped in February. Total biomass production and total rubber yield (rubber or biomass at the time of cutting plus rubber or biomass at the second harvest) were lower in clipped than in unclipped plants. The reduction in rubber yield was most pronounced in plants.
Fast Ionic Actuators with Silver–Silver Chloride Electrodes and a Mixed Ionic Liquid Electrolyte

Excellent conductivity makes silver (Ag) an attractive electrode and current collector material for a variety of devices, also promising faster soft actuators. However, high reactivity challenges the use of Ag in electrochemical systems, as dendritic growth can create undesired conduction pathways and short‐circuit the oppositely polarized electrodes. The challenge of rapid Ag electrochemical migration is addressed using a mixed mixed‐room temperature ionic liquid (RTIL) system (l‐ethyl‐3‐methylimidazolium bis‐(trifluoromethylsulfonyl)‐imide and trihexyl(tetradecyl)phosphonium chloride) that prevents short‐circuiting by engaging the produced Ag+ ions with Cl− anions. The stability of the system is demonstrated on an ionic actuator using Ag–silver chloride (AgCl) electrodes and a mixed‐RTIL electrolyte. The work demonstrates fast (in 5 s) transfer of a large (0.2 C cm−2) charge to high‐specific‐surface‐area carbon without observable dendritic growth in cycling and good electromechanical performance: 4° s−1 deflection rate at 0.8 V s−1 scan rate. Simple spray‐deposition of the Ag–AgCl electrodes promises scalable and cost‐effective fabrication. The combination of high stability and vast charge capacity encourages the engagement of Ag‐based electrodes for many electrochemical applications involving organic electrolytes also beyond robotics.
The Impact of B12 Vitamin and Folate Deficiency on Depression Levels in Breast Cancer Patients

Objective: This study aims to investigate the impact of B12 vitamin and folate deficiency on depression levels in breast cancer patients. Material and Methods: A total of 99 breast cancer patients were included in the study, and sociodemographic data, treatment information, and lifestyle factors were recorded. Depression levels were evaluated using the Beck Depression Inventory, and B12 and folate levels were measured through laboratory tests. Statistical analyses were performed using the SPSS software, and the Mann-Whitney U test was used. Results: Patients who smoked and used alcohol had significantly higher depression scores (p=0.009 and p=0.028, respectively). Additionally, patients with low B12 vitamin levels had significantly higher depression scores (p=0.036). Similarly, patients with folate deficiency also had higher depression scores (p=0.015). Conclusion: This study demonstrates that B12 and folate deficiency can increase depression levels in breast cancer patients. Correcting B12 and folate levels in the management of depression may help improve the quality of life and positively influence the treatment process. Regular monitoring of B12 and folate levels and providing necessary treatment and support are essential in clinical practice.
Nanomaterials in food and agriculture: The big issue of small matter for organic food and farming

Nanotechnology is the study of very small matter, of materials where one dimension is less than 100 nanometres. Surveys reveal that consumers are generally ignorant of nanotechnology, are concerned of its risks versus benefits, expect labelling of products incorporating nanotechnology, and a big issue for respondents is particularly the use of nanotechnology in food. Organic standards of Australia, Canada, Demeter-International and the UK’s Soil Association exclude nanomaterials, however a general nanotechnology exclusion across the organics sector is lacking.
Dynamic Proportional Rankings ∗

Proportional ranking rules aggregate approval-style preferences of agents into a collective ranking such that groups of agents with similar preferences are adequately represented. Motivated by the application of live Q&A platforms, where submitted questions need to be ranked based on the interests of the audience, we study a dynamic extension of the proportional rankings setting. In our setting, the goal is to maintain the proportionality of a ranking when alternatives (i
The GOG Foundation, Inc. Trials Examining the Utility of Radiation Therapy

Introduction Radiation therapy (RT) has an important role in the treatment of gynecologic cancers in the primary, adjuvant, recurrent and palliative settings. The delivery of RT has evolved over the last several decades with advancements in technology through intensity modulated radiation therapy (IMRT), image guidance in external beam RT and brachytherapy. Evolution in beam intensity modulation with either a multileaf collimator or compensating filter have improved target delivery and avoidance of sensitive normal tissue leading to the adoption of Intensity-modulated radiation therapy (IMRT). 1 Additionally improvements in on-board kV imaging (OBI) and cone beam CTs (CBCTs) have allowed for more accurate confirmation that external beam RT is appropriately covering the targets of therapy, while avoiding normal tissue. Early favorable reports of clinical efficacy and decreased acute morbidity resulted in the adoption of IMRT in the treatment of gynecologic cancers.2 There have been randomized and institutional trials comparing IMRT to traditional three-dimensional conformal radiation therapy (3D CRT) in gynecologic cancers, and The National Cancer Institute (NCI) has published guidelines for the use of IMRT in clinical trials.3 As we will see in the clinical trials discussed below, both 3-D CRT and IMRT were allowed in treatment plans, though every IMRT plan required prospective review and adherence to published consensus contouring guidelines. Perhaps most importantly, the incorporation of specific RT guidelines with expert oversight, as part of contemporary trials, has helped ensure high quality radiation delivery on a broad scale. Simultaneously, brachytherapy has undergone similar advances in the ability to image the pelvis and customize the dose delivered to an individual patient. Treatment planning with radiographic plain films has been gradually replaced with true 3D volumetric treatment planning with CT, ultrasound and MRI, allowing for improved target and normal tissue definition.4 Low dose rate (LDR) brachytherapy with radium capsules initially, and subsequently Cesium 137 over the course of 40-80 hours, has been largely supplanted with high dose rate (HDR) treatment with Iridium 192 in the U.S., delivered over a few minutes in three to five fractions.5 Lastly, the increased use of supplemental interstitial catheters in addition to traditional tandem and ovoid based treatments for locally advanced cervical cancer has enabled further customization of dose and radiation delivery.6 The combination of these three factors have resulted in improved cervical cancer control rates of over 90% and decreased grade 3 toxicity rates under 10%, even in stage IIIB and IVA disease.7
Numerical modeling of multiscale wave propagation phenomena in fluid-rock systems

Two–dimensional scattering of elastic waves in a medium containing a circular heterogeneity is investigated with an analytical solution and numerical wave propagation simulations. Different combinations of finite difference methods (FDM) and finite element methods (FEM) are used to numerically solve the elastodynamic wave equations. Finite difference and finite element techniques are applied to approximate both the time and space derivatives and are combined in various ways to provide different numerical algorithms for modeling elastic wave propagation. The results of the different numerical algorithms are compared for simulations of an incident plane P–wave that is scattered by a mechanically weak circular inclusion whereby the diameter of the inclusion is of the same order than the P–wave’s wavelength. For this scattering problem an analytical solution is available and used as the reference solution in the comparison of the different numerical algorithms. Staircase–like spatial discretization of the inclusion’s circular shape with the finite difference method using a rectangular grid provides accurate velocity and displacement fields close to the inclusion boundary only for very high spatial resolutions. Implicit time integration based on either finite differences or finite elements does not provide computational advantages compared to explicit schemes. The best numerical algorithm in terms of accuracy and computation time for the investigated scattering problem consists of a finite element method in space using an unstructured mesh combined with an explicit finite difference method in time. The computational advantages and disadvantages of the different numerical algorithms are discussed.

Identifying Service Delivery Strategies for Ethnically Diverse Users of a Wildland-Urban Recreation Site

Service delivery has become an increasingly important part of managing public lands for recreation. The range of preferences held by ethnically diverse users of recreation sites may warrant the development of more than one service delivery strategy. Two questions were examined: (1) Are there differences in site perceptions that can be identified on the basis on ethnicity? and (2) If so, how many service delivery strategies are necessary to meet the needs of the site users? Three ethnic groups were identified, but most differences were found between Anglos and Hispanics. These results indicate the development of two service delivery strategies could meet the needs of most recreationists.
INVESTIGATION OF TEACHING SELF-EFFICIENCY OF ERCIYES UNIVERSITY PHYSICAL EDUCATION TEACHER DEPARTMENT FINAL YEAR STUDENT

The general purpose of this research is to reveal the results and make suggestions with the research of the teaching competence of the last year students of the Department of Physical Education Teaching at Erciyes University. The research consists of 45 students selected by random cluster sampling from the 4th grade students studying at the Department of Physical Education and Sports Teaching at the Faculty of Sport Sciences at Erciyes University. Volunteers participating in the study were asked to fill in the "Ohio Teacher Competency Scale", a demographic information form developed by the researcher, developed by Tschannen-Moran & Woolfolk-Hoy (2001) and adapted into Turkish by Baloğlu and Karadağ (2008). IBM-SPSS (Statistical Package for The Social Sciences) 22 statistical package programs were used in the analysis of the data. The arithmetic average and standard deviation of the students’ scores from the Ohio Teacher Competency Scale are presented as x SD. In pairwise comparisons, a t-test was used for independent groups. As a result, when the students' self-efficiency was examined according to the variables of gender and type of sport, no statistically significant difference couldn't be found between the groups. Teacher candidates feel ready for teaching to a large extent. Article visualizations:
Feedback Optimization Strategy for Rotational Alignment Echo Spectroscopy

The recent discovery of rotational echoes has contributed to extend the applications of field‐free molecular alignment to short time scales, namely to a temporal region preceding the first alignment revival of the molecule. Most echo measurements require adjusting the position of the echo over time, which in the case of molecular alignment echo unavoidably leads to a change in its amplitude, unless the intensity of the pulse sequence triggering the echo is properly modified. Herein, it is proposed to avoid this drawback by using an optical pulse shaper steered by a learning algorithm. It is demonstrated that a temporal shaping, whose characteristics are optimized to maintain a constant echo amplitude regardless of its creation time, can be generated by controlling the spectral phase and amplitude of the laser pulse which are then used in an open‐loop control system. As a proof of principle, the optimization strategy is applied to the observation of short‐term dissipative dynamics of laser‐aligned molecules exposed to collisions and to the measurement of associated decoherence and population decay time constants.
Upscale feedbacks observed and modeled during the mesoscale predictability experiment

Woznicki, Joseph M. M.S., Purdue University, August 2014. Upscale Feedbacks Observed and Modeled During the Mesoscale Predictability Experiment (MPEX). Major Professor: Robert Trapp. All modes of deep convective storms perturb their local environment on temporal and spatial scales that are larger than the storm itself. Such upscale feedbacks associated with the mesoscale convective systems (MCSs) are well known; much less is known about the feedbacks associated with supercell thunderstorms that, like MCSs, represent a highly organized convective mode. Data from the Mesoscale Predictability Experiment (MPEX), in addition to CM1 model simulations, provide the means to quantify these upscale feedbacks and determine their relative influence on the subsequent predictability of the atmosphere. The 700-500 mb lapse rate (MLR), mean-layer CAPE up to 475 mb (MLCAPE475), and 1-6 km wind shear (S16) are calculated from the raw MPEX sounding files and CM1 output for three supercell cases and one squall line case. The most significant upscaling occurs in the lowest levels of the atmosphere, and is introduced by each storm’s cold pool boundary.
