Thin film thermoelectric elements of p–n tin chalcogenides from chemically deposited SnS–SnSe stacks of cubic crystalline structure

SnS and SnSe thin films of cubic (CUB) crystalline structure prepared by chemical deposition are recent additions to their orthorhombic polymorphs. These structures are simple cubes with lattice constants 11.587 and 11.963 Å, respectively, holding 32 formula units. Their chemically deposited thin films have direct optical bandgaps, 1.76 and 1.4 eV, respectively. Electrical conductivity of these films are 10–8 to 10–6 Ω–1 cm–1, which are low for photovoltaic or thermoelectric applications. We report that SnS-CUB/SnSe-CUB thin film stacks convert to p-type SnSxSe1−x or n-type SnSxSe2−x when heated at 350 °C for 30 min in a nitrogen ambient in presence of selenium vapor, depending on its abundance. They have an onset of optical absorption at 1.3–1.5 eV. The electrical conductivity of the stack increases from 1.3 × 10–5 Ω–1 cm–1 toward 0.3 Ω–1 cm–1 for p-type SnSxSe1−x or 0.8 Ω–1 cm–1 for n-type SnSxSe2−x. Seebeck coefficients (S) are, + 0.6 mV K−1 for the p-type and −0.4 mV K−1 for the n-type material in the 25 °C–45 °C interval. Three-element n-p-n thermoelectric devices have S, 1.1–1.6 mV K−1. We analyze the feasibility of solar radiation as the heat source for such devices.

Supraclavicular versus Infraclavicular Subclavian Vein Catheterization in Coronary Artery Bypass Graft Surgery

Background: Percutaneous central vein catheterization is one of the most invasive procedures commonly performed by anesthesiologists during cardiac surgery. Objectives: The aim of this study was to investigate the complications of supraclavicular (SC) versus infraclavicular (IC) approaches for subclavian vein catheterization during coronary artery bypass graft surgery. Materials and Methods: Between October 2014 and June 2015, this prospective, randomized clinical trial was performed in 280 patients. The patients were randomly cannulated by SC or IC approach. The success and complication rates were compared for the two approaches. The outcome of this study was analyzed using SPSS software and through Chi-square test. Results: In the first attempt of catheterization, the success rate in SC (78.6%) group was lower than IC (94.3%) group (P = 0.0001). The overall success rate in two attempts were 136 (97.1%) in the IC approach and 132 (94.3%) in the SC approach (P = 0.238). In 12 (4.3%) patients, subclavian catheterizations were failed after two attempts in both approaches. In 28 (10%) patients, hematoma at puncture site occurred, 1 (0.7%) in IC approach, and 27 (19.3%) in SC approach (P = 0.0001). The differences in other complications on two approaches were statistically insignificant. Conclusions: Compared with the SC approach, the IC approach resulted in fewer hematomas at puncture sites. The incidence of overall cannulation failure and other complications were similar on both approaches.

The effect of becoming a legal sex worker in Senegal on health and wellbeing

Senegal is the only low-income country where prostitution is legal and regulated by a health policy. To solicit clients in public places, female sex workers need to register with a health facility and attend monthly routine health checks aiming at testing and treating sexually transmitted infections and distributing free condoms. While this policy was first introduced in 1969 to limit the spread of sexually transmitted infections, there is no evidence so far on its impact on sex workers' health. The paper aims to fill this gap by exploiting a unique data set of legal and illegal Senegalese sex workers. Using propensity score matching we find that becoming a registered sex worker leads to an improvement in health but has a detrimental effect on wellbeing. Precisely, registered sex workers are found to engage in riskier and more degrading sex acts and to have less social support from their co-workers. Our results are robust to the use of a super learner to improve the specification of the propensity score and the use of entropy balancing in order to achieve covariate balance. The results are also robust to the violation of the conditional independence assumption. The results suggest that psychological services should be offered to sex workers part of the registration policy in order to overcome its negative effect on wellbeing.
Typical Expression Of Cognitive Dissonance And Consonance In The Course Of Argumentation Among Primary-School Children Playing Chess

The research aims to reveal the typical expressions of cognitive dissonance and consonance among the primary-school children by their argumentations upon their deed. The relevance of the research stems from the applicability of the study of the phenomena of dissonance and consonance, which inherently emerge in the sphere of argumentation among the children who study how to play chess. Cognitive dissonance and consonance in the sphere of argumentation in the course of the game of chess are gradually transforming both into the respective reference points – relevant to the situation given, and into the emotional and behavioural manifestations – either adequately or inadequately expressed and, by the logical and inner conflict, are observed as the result of juxtaposition of the realms of emotions and logic. The present research evidences that, in the case of similar chess skills, the manifestation of cognitive dissonance, and the own argumentation as well are detectable within the domain of extroversion – emotional instability. Such children, even more than the introverts, need the school psychologist’s support. The cognitive consonance is typical of those of the children involved who are ready to gain new experience and appear to be more positively charged towards their rivals or opponents.
An Empirical Framework toUnderstand the Antecedents of Work Engagement and Employability in the Thai Universities

Present research is basically concerned to investigate the impact of ethical leadership and creative self-concept on work engagement and employability. In addition to that, the study has examined meaningful work as the mediator, and cognitive emotional regulation is taken as the significant moderator between leadership and meaningful work. The study has used the survey-based methodology, and the questionnaire is adopted from the prior findings. In order to reply to the questions raised in current research, the SEM-PLS tool is employed. The data is collected from Thai universities; the findings of the study have provided support to the proposed results. The mediation and moderation effect appears in a significant. The study broached an argument that Happily engrossed in ones work and fully concentrated is the state of absorption. Engrossment, satisfaction and full concentration of job-related tasks that one individual receives refers to this component of absorption, thus deriving pleasure from work, the eudemonic approach is also referred to this state. Such individuals having the state of absorption have difficult often to detach or disengage their jobs from themselves. The results of the research study might provide help to the policymakers, researchers, and HR personnel in understanding the issues related to employability, and work engagement.
Initial rotor alignment method for doubly salient electromagnetic machine position sensorless startup

The initial rotor alignment process plays an important role in `align and go' which is a simple, implementable and widely industrial used position sensorless startup method. To deal with the possible jitter and reverse in the initial startup process, this Letter proposes a novel initial rotor alignment method for the position sensorless startup of the doubly salient electromagnetic machine (DSEM). According to the analysis of the generated electromagnetic torque, the relation between the alignment pulse and stable locating position is studied at first. Then, to improve the initial startup performance, the alignment pulse of switching on two upper transistors and one lower transistor is proposed to be injected as the alignment pulse since the stable locating position is around the middle point of rotor sector; it owns the benefit of better selection for the initial energising phase windings. The initial sensorless startup performance is desired to be improved in terms of no jitter or reverse. The experiments of initial alignment, as well as, the full process of the sensorless startup based on `align and go' on a 12/8-pole DSEM validate the flexibility and effectiveness of the proposed method.
Identifying the properties of epoxy composites filled with the solid phase of wastes from metal enterprises

The article addresses the issue related to the disposal of dust from steel industry as a reinforcing filler for epoxy composites. The polymer composition of "cold welding" that has been developed and studied includes epoxy dian oligomer, amine hardener and the filler – finely dispersed waste of metals. Polyethylene polyamine was used as a hardener in order to improve heat resistance and strength characteristics. Manganese triacetate was used in order to decrease the temperature and reduce the time of curing. The possibility was established to dispose of finely dispersed metal-containing waste from metallurgical production to be used a filler for epoxy composites of cold curing. It was revealed that the optimal content of dusts from foundries in the composite is at the level of 45–60 %. At this content, there is the highest impact resistance at the level of 40–50 MPa and a softening temperature in the range of 170–190 °С. It was established that at an increase in the amount of a filler from 40 % to 70 %, the cross-linking degree increases by 88 % to 98 %, respectively. However, at the content of the filler less than 45 % or exceeding 60 %, the impact resistance of the resulting composites decreases. At the content of a filler in the composite less than 45 %, the cause of low values of impact resistance and softening temperature could be the low cross-linking degree, less than 90 %. A decrease in these properties of composites at the content of the filler exceeding 60 % could be associated with the formation of a heterogeneous structure of filler. In the compositions with the highest performance characteristics, there is an optimized content of the filler and catalyst. Using a hardener and a curing catalyst in quantities of 3–3.5 and 1.5–2 %, respectively, makes it possible to shorten curing time by up to 2 hours. In general, the resulting epoxy composites are superior in their performance to known cold-curing analogs. The dependences of impact resistance, softening temperature, and cross-linking degree on the content of waste in the composite were derived, which make it possible to calculate the optimal formulation for composites depending on the required properties
Impacts of weather, habitat, and reproduction on the survival and productivity of wild turkeys in the northern Black Hills, South Dakota

The study of population ecology is motivated by a desire to understand variation in the factors that drive wildlife population dynamics. Robust vital rate estimates are crucial for effective wildlife conservation and management, particularly for at-risk or harvested species. In avian populations, the survival of females, nests, and young are important drivers of population growth, although the relative importance of each rate can differ among species. Annual and regional variation in vital rates within species is common; further, local climatic and habitat conditions may influence population dynamics. During 2016 – 2018, we used radio telemetry to study the impacts of weather and habitat conditions on the survival and productivity of Merriam’s wild turkeys (Meleagris gallopavo merriami) in the northern Black Hills of South Dakota. Specifically, we quantified the impacts of 1) precipitation and reproductive effort on hen survival, 2) precipitation and habitat conditions on nest survival, and 3) precipitation and temperature on early poult survival. Precipitation reduced the survival of hens and nests, although the magnitude depended on the hen’s incubation status or the vegetation characteristics at the nest site. Based on precipitation data from 2017, the estimated annual survival rate for a hen that did not incubate was 0.535 (SE = 0.038), whereas that and for a hen that incubated for 26 days was 0.436 (SE = 0.054). The probability that a nest would survive from initiation to hatching for a nest initiated by an adult hen on the median date of nest incubation in 2017 was estimated to be 0.432 (SE = 0.084). The estimated probability that a poult would survive from hatching to 4 weeks of age was 0.387 (SE = 0.061). Our results clearly demonstrate a negative cost of reproduction, as predicted by life-history theory, and show that hens and nests in this ecosystem are more vulnerable to predation during or immediately following rainfall, as predicted by the moisture-facilitated nest-predation hypothesis. Survival and productivity of turkeys was lower in our study area than in other portions of the Black Hills; we recommend that managers take steps to limit human-induced hen mortality of this important game species.
Efficient Low-Complexity Antenna Selection Algorithms in Multi-User Massive MIMO Systems With Matched Filter Precoding

In this work, two efficient low complexity Antenna Selection (AS) algorithms are proposed for downlink Multi-User (MU) Massive Multiple-Input Multiple-Output (M-MIMO) systems with Matched Filter (MF) precoding. Both algorithms avoid vector multiplications during the iterative selection procedure to reduce complexity. Considering a system with <inline-formula><tex-math notation="LaTeX">$N$</tex-math></inline-formula> antennas at the Base Station (BS) serving <inline-formula><tex-math notation="LaTeX">$K$</tex-math></inline-formula> single-antenna users in the same time-frequency resources, the first algorithm divides the available antennas into <inline-formula><tex-math notation="LaTeX">$K$</tex-math></inline-formula> groups, with the <inline-formula><tex-math notation="LaTeX">$k$</tex-math></inline-formula>th group containing the <inline-formula><tex-math notation="LaTeX">$N/K$</tex-math></inline-formula> antennas that have the maximum channel norms for the <inline-formula><tex-math notation="LaTeX">$k$</tex-math></inline-formula>th user. Therefore, the Signal-to-Interference plus Noise Ratio (SINR) for the <inline-formula><tex-math notation="LaTeX">$k$</tex-math></inline-formula>th user can be maximized by selecting a subset of the antennas from only the <inline-formula><tex-math notation="LaTeX">$k$</tex-math></inline-formula>th group, thereby resulting in a search space reduction by a factor of <inline-formula><tex-math notation="LaTeX">$K$</tex-math></inline-formula>. The second algorithm is a semiblind interference rejection method that relies only on the signs of the interference terms, and at each iteration the antenna that rejects the maximum number of interference terms will be selected. The performance of our proposed methods is evaluated under perfect and imperfect Channel State Information (CSI) and compared with other low complexity AS schemes in terms of the achievable sum rate as well as the energy efficiency. In particular, when the Signal-to-Noise Ratio (SNR) is 10 dB, and for a system with 20 MHz of bandwidth, the proposed methods outperform the case where all the antennas are employed by 108.8 and 49.2 Mbps for the first and second proposed algorithms, respectively, given that the BS has perfect CSI knowledge and is equipped with 256 antennas, out of which 64 are selected to serve 8 single-antenna users.
How to Eliminate Detour Behaviors in E-hailing? Real-time Detecting and Time-dependent Pricing

With the rapid development of information and communication technology (ICT), taxi business becomes a typical electronic commerce mode. However, one traditional problem still exists in taxi service, that greedy taxi drivers may deliberately take unnecessary detours to overcharge passengers. The detection of these fraudulent behaviors is essential to ensure high-quality taxi service. In this paper, we propose a novel framework for detecting and analyzing the detour behaviors both in off-line database and among on-line trips. Applying our framework to real-world taxi data-set, a remarkable performance (AUC surpasses 0.98) has been achieved in off-line classification. Meanwhile, we further extend the off-line methods to on-line detection, a warning mechanism is introduced to remind drivers and an excellent precision (AUC surpasses 0.90) also has arrived in this phases. After conducting extensive experiments to verify the relationships between pricing regulations and detour behaviors, some quantitative pricing suggestions, including rising base fare and reducing distance-based fare rate, are provided to eliminate detour behaviors from the long term.
Anaerobic Energy Supply During Maximum-Intensity Short-Term Voluntary Sustained Exercise in Man.

The purpose was to directly assess the relative contributions of the anaerobic energy releasing pathways to ATP provision during very brief (2-14s) maximal isometric contractions in human skeletal muscle, and to examine the recovery processes following such exercise. Eleven males performed unilateral sustained maximal isometric contractions of the knee-extensor muscles. Ten needle biopsy samples [2 pre-exercise (PreEx), 4 exercise (Ex), and 4 recovery (Rec) samples] were obtained from each subject over 3 separate testing sessions. Circulation was occluded at the upper thigh prior to all biopsies. Ex samples were taken immediately following 2-14s of maximal voluntary contraction. Contraction times were randomly pre-determined such that 6 biopsies were obtained following each of 2, 4, 6, 8, 10, 12, and 14s of contraction. Rec samples were collected 10, 20, 30, 40, 60, 120, and 180s following 14s maximum contractions. Significant changes occurred for both phosphocreatine (PCr) and lactate concentration within the initial 2s (n=7, ps0.05) of contraction. In 14s, PCr concentration decreased to 53.3% of the PreEx value at a rate of 2. 53±0 . 18 mmol· kgdm · s, while muscle lactate increased to approximately 8 times the initial value, at a steady rate of 1. 52±0 . 10 mmol·kg-dm· s•
