Exaggerated natriuresis in the conscious spontaneously hypertensive rat.

: In response to an acute saline load, many patients with essential hypertension exhibit an exaggerated natriuresis relative to normotensive controls. In the present study, the urinary responses of conscious,Okamoto-strain, spontaneously hypertensive rats (SHR), and Wistar-Kyoto strain normotensive rats (NTR) to an acute saline load were evaluated to determine if a similar exaggerated natruiresis exists in this form of hypertension. Twelve rats of each strain per group (12 weeks of age) were housed in metabolism cages for 1 week. Systolic blood pressures (tail cuff) were significantly different (206+/- 9 mm. Hg in SHR and 135 +/- 3 mm. Hg in NTR). After a 4-hour control urine collection, 6 ml. of 0.9 per cent sodium chloride were given by gavage. Urine was collected again for 2 hours. Control urinary excretions of sodium, potassium, and creatinine in SHR and NTR were 11.2 +/- 4.8 muEq per hour, 50.1 +/- 7.6 muEq per hour, and 39.9 +/- 5.5 mg. per hour in SHR, and 13.8 +/- 2.4 muEq per hour, 34.9 +/- 5.5 muEq per hour, and 37.5 +/- 7.1 mg. per hour in NTR, respectively. The respective control values for sodium, potassium, and creatinine excretion in the two groups were not significantly different. Following the saline load, sodium and creatinine excretion rates were significantly elevated in both groups of rats. However, the increase in sodium excretion in SHR (60.8 +/- 7.2 MUEq per hour) was more than double and significantly different from that of the NTR (26.6 +/- 3.7 muEq per hour). In contrast, the increments in creatinine excretion in the two groups of rats were not significantly different from each other. In the NTS, urinary potassium excretion was significantly elevated (59.0 +/- 7.9 muEq per hour) whereas in SHR it was not significantly altered (12.0 +/- 8.8 muEq per hour). The change in urinary creatinine excretion as an index of change in glomerular filtration rate suggests that the greater increase in sodium excretion by the SHR was the result of decreased fractional reabsorption of sodium and not the result of a greater increase in glomerular filtration rate. The exaggerated natriuretic response to salt loading in SHR resembles that in hypertensive man except that in SHR, a simultaneous kaliuretic response is absent.
Resource Allocation in 5G IoV Architecture Based on SDN and Fog-Cloud Computing

In the traditional cloud-based Internet of Vehicles (IoV) architecture, it is difficult to guarantee the low latency requirements of the current intelligent transportation system (ITS). As a supplement to cloud computing, fog computing can effectively alleviate the bottlenecks of cloud computing bandwidth and computing resources and improve the quality of service (QoS) of the IoV. However, as a distributed system that operates near users, fog computing has a complicated network structure. In the complex and dynamic IoV environment, to effectively manage these computing resources with different attributes and provide high-quality services, it is necessary to design an efficient architecture and a resource allocation algorithm. Therefore, on the basis of fog-cloud computing and software-defined networking (SDN), a novel 5G IoV architecture is designed. In addition, after fully considering the service requirements of the IoV, a model of four objectives is constructed, and a many-objective optimization algorithm is proposed. The experiment results show that the proposed algorithm outperforms the other state-of-the-art algorithms.
Nitrogen balance response to varying levels of dietary protein in slow-growing Windsnyer pigs

Protein requirements for slow-growing pigs have not been defined. The study was designed to determine the relationship between the level of dietary protein and nitrogen balance in slow-growing Windsnyer pigs. Thirty Windsnyer pigs with an initial bodyweight of 34.7 (SD = 0.85) kg were randomly assigned to six experimental diets containing 193, 174, 154, 135, 117, and 97 g/kg of crude protein (CP). Pigs were penned individually. There were five pigs in each diet. The faecal nitrogen output (NFO) showed a decreasing quadratic relationship with protein level. A linear relationship between protein level and urinary nitrogen excretion was observed (P =0.0001). The total nitrogen excreted showed a significant quadratic relationship to decreasing levels of CP in the diets (P =0.0001). The apparent digestibility of nitrogen had a linear relationship with dietary CP level (P =0.0005). A quadratic relationship between dietary protein level and N utilization was observed (P =0.0001). The optimum protein level for total nitrogen excreted, nitrogen utilization and biological value of feed protein were attained at 135 g/kg protein level. The efficiency of nitrogen utilization supports the low protein diet. The present results suggest reducing the dietary protein level for Windsnyer pigs to decrease amount of excreted N that is deposited into the environment.Protein requirements for slow-growing pigs have not been defined.

Power-Efficient Software-Defined Data Center Network

The energy consumed by data centers has been growing rapidly in recent years. Among all the major contributors to the power consumption of entire data centers, data center network (DCN) can account for up to 20% of the total power consumption. In this article, we first devise a power-efficient software-defined DCN (PESD-DCN) framework, which can achieve desirable power efficiency, avoid potential link congestion, and reduce frequent device state transition. Then, we formulate the optimization problem of maximizing the radio full-utilized devices to all devices. To solve it, we propose correlation-aware flow routing (CFR) algorithm, which leverages correlation-aware flow consolidation (CFC) technique to improve energy efficiency, avoid the potential link congestion, and reduce frequent device state transition. Moreover, to further improve the DCN energy efficiency, we propose flow rerouting, link rate adaptation, and device sleeping (FLD) algorithm. Finally, simulation results demonstrate that PESD-DCN can achieve a good performance. More specifically, in comparison to the other baseline algorithms, PESD-DCN can achieve up to 79.19% energy efficiency, 67.1% decrease in switch state transition (SST), and 55.4% decrease in link state transition (LST).
Lab Reports and Horror Stories: Leveraging Chemistry Majors’ Writing Interests for Student Engagement and Retention

Author(s): Nicholes, Justin | Abstract: Perceived divisions between arts/writing and science/disciplinary writing stymie science students' writerlyngrowth. This study adopted a case-study qualitative design to discover how science undergraduates at one public university in the eastern U.S. understood writing and how they evaluated creative or personal writing in relation to their science identities. Findings show that science majorsnin this sample defined science writing as distinct from others kinds of writing, but they also saw creative writing as personally enjoyable and valuable. Conclusions are made that science educators may be able to leverage creative, imaginative writing that used in industry, such as science fiction prototyping, to give students chances to demonstrate how creative narratives do not lie beyond the boundaries of scientific discourse.
Extraction of Curcumin and Essential Oil from Curcuma longa L. by Subcritical Water via Response Surface Methodology

In this study, subcritical water extraction (SWE) was applied to extract the essential oil (especially curcumin) from Curcuma longa L. (turmeric) rhizome. Response surface methodology was used to evaluate the extraction conditions. Experiments were carried out using a three-factor Box–Behnken design under following conditions: temperature (90, 120 and 150C), water flow rate (1, 2.5 and 4 mL/min) and mean particle size (0.5, 1 and 1.5 mm). This is the first time that effects of mentioned variables were considered on SWE of curcumin. The optimum conditions were temperature of 150C, water flow rate of 1 mL/min and mean particle size of 0.5 mm. The maximum curcumin extraction yield was 90.1947 ± 0.26%, which was in a good agreement with the predicted value of 92.0097%. The extracts were analyzed by gas chromatography and gas chromatography-mass spectrometry. Also, results of SWE were compared with conventional methods. Practical Applications Curcumin is an important pharmacological agent that can be extracted from turmeric rhizome. In recent years, subcritical water has been used as a solvent for extraction of flavors, fragrances and antioxidant components from plant materials. Subcritical water is a good solvent for curcumin as well as other organic compounds but is safer than the organic solvents. Subcritical water extraction of curcumin from turmeric rhizome is an alternative method for increasing the quality of the extract.
Impact of Spectators’ Perceptions of Corporate Social Responsibility on Regional Attachment in Sports: Three-Wave Indirect Effects of Spectators’ Pride and Team Identification

The professional sports events industry is becoming immensely popular due to a global social shift toward larger numbers of spectators at sports events and an ever-increasing variety of such events. This study aimed to investigate the impact of spectators’ perception of corporate social responsibility on regional attachment by applying social identity theory. The present study introduces two mediators, namely, spectators’ pride and team identification, to enlighten the relationship between spectators’ perception of corporate social responsibility and regional attachment, thus contributing to the literature on corporate social responsibility in sports. This quantitative study used a time-lagged approach to collect data in three waves at a time interval of one week and the final sample consisted of 511 respondents (i.e., spectators). Hierarchical regression analysis bootstrapping approach was utilized to analyze the hypothesis. We found that the spectators’ perceptions of corporate social responsibility positively influenced their team identification, and this relationship was mediated by spectators’ pride. In addition, spectators’ pride positively influences regional attachment, and this relationship is mediated by team identification. These findings provide new directions for understanding corporate social responsibility, team identification, spectators’ pride, and regional attachment in sports contexts. The practical and theoretical implications are discussed.
Simulating the flow around a train passing through a tornado

A flow simulation was developed to understand the flow surrounding a train that was passing through a tornado and the resulting aerodynamic forces acting on the vehicle. Unsteady Reynolds averaged Navier-Stokes equations were solved to reproduce a previously-conducted laboratory experiment, in which a model train runs through a stationary tornado-like swirling flow. The simulation reproduced the unsteady aerodynamic forces acting on the train reported in the experiment. Furthermore, the computation successfully revealed how the flow field changes as a train passes through a tornado-like swirling flow.
Service years of health professionals are associated with tuberculosis infection control practice in Ethiopian Teaching Hospital

Introduction proper tuberculosis (TB) infection control (TBIC) practice of health professionals is one of the effective TB prevention approaches. Despite this reality, the TBIC practice of health care workers was not been well studied. This study assessed the TBIC practice of health professionals and associated factors in Mizan Tepi University Teaching Hospital, southwest Ethiopia. Methods an institution based quantitative cross-sectional study was conducted from September 1 to 30, 2019, by including all health professionals in the hospital. Participants who answered at least 50% of TBIC practice questions correctly were categorized as having good TBIC practice. Binary logistic regression was used to identify factors associated with the practice of the participants. The odds ratio with a 95% confidence interval and p-value was used to measure the strength of association; the significant association was declared at a p-value less than 0.05. Results the study found that 64.1% (95% CI: 56.6%, 70.7%) of the participants had good TBIC practice. More than half, 102(51.5 %) of study participants have service years of greater than or equal to five years. Only the service year of health professionals was significantly associated [95%CI (AOR= 2.43; 95%CI: 1.28, 4.6)] with the respondents´ TBIC practice. Conclusion only less than two-third of health professionals had good TBIC practice which is inadequate. And also experienced staff had significantly better TBIC practice. As a result, health professionals in MTUTH should be supported to practice TBIC as routine activity and opportunities should be made for senior staffs to share their TBIC experiences with others.
Impacts of health and economic costs on street children working as waste collectors in Dhaka City

This research investigates the health impacts and access to health services by children who are engaged in waste collection in Dhaka, the capital city of Bangladesh. The relevant qualitative data were collected through expert interviews and personal observations, while quantitative data were gathered through a face-to-face questionnaire survey given to 50 street children who collected waste at the landfill site located in Dhaka city’s Matuail area. The results indicate that 94% of these children have suffered from many health problems, such as fever and fatigue due to tiredness, dizziness, and vomiting. Consequently, a significant portion of their daily income is spent on medical treatment. This study suggests that the waste collection system must integrate modern technological, health and environmental resources so that: firstly, they do not harm waste collectors; and secondly, rehabilitate the street children and give them better access to acceptable basic amenities. This is a priority the city authorities.
Dermatology residency research policies and support: A national USA survey

s, presentations, and publications; 10.1 volunteer experiences; and 4.7 research experiences [1]. In contrast to the highly structured application process, Dermatology programs themselves vary widely in their features, approaches, demographics, and requirements for research. A minority of Dermatology residency programs have formally allotted time devoted to research within their curricula, and many programs’ requirements for research are much broader and more
Semiparametric APC analysis of destination choice patterns: Using generalized additive models to quantify the impact of age, period, and cohort on travel distances

This study investigates how age, period, and birth cohorts are related to altering travel distances. We analyze a repeated cross-sectional survey of German pleasure travels for the period 1971–2018 using a holistic age–period–cohort (APC) analysis framework. Changes in travel distances are attributed to the life cycle (age effect), macro-level developments (period effect), and generational membership (cohort effect). We introduce ridgeline matrices and partial APC plots as innovative visualization techniques facilitating the intuitive interpretation of complex temporal structures. Generalized additive models are used to circumvent the identification problem by fitting a bivariate tensor product spline between age and period. The results indicate that participation in short-haul trips is mainly associated with age, while participation in long-distance travel predominantly changed over the period. Generational membership shows less association with destination choice concerning travel distance. The presented APC approach is promising to address further questions of interest in tourism research.
An Efficient and Reliable Solid-State Circuit Breaker Based on Mixture Device

In this letter, a novel solid-state circuit breaker (SSCB) based on mixture device (MD-SSCB) is proposed for dc distribution systems. The proposed MD-SSCB can actively interrupt faults without introducing additional thyristor, charging power supply, and charging strategies. Besides, the interruption capability of the MD-SSCB is not affected by the parameters of the outer circuit. As a result, the MD-SSCB has advantages of compact structure, economic design, high efficiency, and high reliability. Moreover, the MD-SSCB can turn off its thyristors without reverse voltage stress, which eliminates the severe reverse overvoltage problem in the fault-interrupting process, and hence further enhances the reliability of the breaker. Detailed operation principle and design guidelines of the MD-SSCB are discussed through mathematical modeling. The feasibility of the proposed breaker is validated by experimental results.
Effect of twist level on the mechanical performance of S-glass yarns and non-crimp cross-ply composites

High modulus/high strength continuous fibres are used extensively for manufacturing textile preforms, as a reinforcement, for composites due to their excellent specific properties. However, their brittle behaviour and tendency to separate easily into individual filaments or bundles can lead to damages during manufacturing processes such as weaving and braiding. Thus, the critical step in the development of an optimal yarn for textile-reinforced composites is to find an optimum twist, which results in a minimum loss of properties of the composite laminates, while maintaining good processability and sufficient strength for textile and/or composite manufacturing. In this study, twist level has been varied to improve the handling and tensile properties of S-glass yarns (i.e. tensile strength). Varying levels of yarn twist (15–40 twists metre−1) were employed to study its impact on the tensile properties (i.e. tensile strength, modulus, elongation at break etc.). Furthermore, the effect of twist on the tensile properties of non-crimp cross-ply composites produced via vacuum infusion process was studied. It was observed that mechanical performance (i.e. tensile strength properties) of twisted yarns is improved up to 30 twists metre−1 while it is deteriorated at 40 twists metre−1. At yarn level, the experimental results were compared with theoretical estimations utilizing existing models for twisted yarns properties. Discrepancies were observed between experimental and theoretical results especially for high level of twist. The tensile strength and elongation of S-glass cross-ply composites at all levels of twist were higher compared to the composite laminates manufactured by using non-twisted yarns. At composite level, the experimental results were also computed employing rule of mixture and good agreement was observed between experimental and predicted results.
‘Together we stand’: coalition-building in the Italian and Spanish feminist movements in times of crisis

We analyse coalition-building in feminist mobilisations in times of crisis in two similar cases: Spain and Italy. Based on social movement literature, we develop two key arguments. First, in austerity-ridden scenarios, connecting socio-economic grievances and feminist demands is key for the feminist mass mobilisations to follow. Second, anti-austerity struggles must resonate across different dimensions of coalition-building, both within the feminist movements and across feminists and other actors, such as LGBTQ collectives and anti-austerity challengers. The data used throughout the article come from semi-structured interviews with activists in Italian and Spanish feminist grass-roots organisations. Our results suggest that times of neoliberal crisis may present opportunities not only to advance the feminist agenda, but also to foster alliances within the feminist milieus and between feminists and other relevant collective actors. These alliances might well extend beyond the period of greatest hardship.
A Compact Conformal Stub-Loaded Long Slot Leaky-Wave Antenna With Wide Beamwidth

This letter presents a compact, conformal, stub-loaded longitudinal slot leaky-wave antenna at Ku-band. The antenna is designed with a short length of 2. 75λ at the center frequency. The effect of flange length on the transverse plane half-power beamwidth (HPBW) is studied. The design of leaky-wave antenna within this short length and flange studies on transverse plane HPBW are the novelty of this letter. Antenna design, dispersion curves, and a comparison of the simulation and measurement results are presented. The radiation efficiency of 95%, a gain of 8 dBi, a tilt angle of 30°, and longitudinal plane HPBW of 42° are achieved. Transverse plane HPBW of 168° and 4 dB beamwidth of 180° are achieved, which aids to achieve an omnidirectional pattern using two antennas when placed in the cylindrical shell with a 180° angular separation.
Reflections on English as a Foreign Language Teacher Burnout Risk Factors: The Interplay of Multiple Variables

This study represents an investigation into the interplay of the English as a Foreign Language (EFL) teacher burnout and such teacher-related variables as emotional intelligence, personality traits, teaching experience, self-efficacy, school type, gender, academic degree and age. This is a research report of a study on 124 secondary school EFL teachers with BA, MA, and PHD academic degrees. Findings of correlation and sequential multiple regression analyses suggest that EFL teacher burnout is likely to result from several factors with emotional intelligence being by far the strongest predictor of them. It was also found that emotional intelligence and self-efficacy have a negative moderate correlation with teacher burnout. Strong correlations were also found between emotional intelligence and self-efficacy, age and self-efficacy, and age and experience. No significant relationship was found between burnout and age, experience or personality. Some critical points are raised for the education system in Iran and practical implications are suggested.
