Short term effect of integrated Yoga on anxiety, stress and heart rate variability in first year medical student

Introduction: Medical students are exposed to various stresses, which is known to affect cardiovascular system which can be assessed by noting the heart rate variability (HRV). Aims: To assess the anxiety, stress and HRV in first year medical students and study the effect of one month integrated yoga intervention on them. Materials and Methods: Spielberger state-trait anxiety inventory (STAI) and Perceived stress scale (PSS) were administered to 150 first year medical students. 60 students with a high anxiety and stress score were selected on the basis of specific inclusion and exclusion criteria and divided into study and control groups. A baseline HRV was documented on all 60 students. 30 students in the study group underwent supervised yoga intervention for one month. Post interventional assessments of anxiety, stress and HRV were done in both groups (study and control group). Paired t test was used to determine the statistical difference in pre and post interventions and independent t test was used to determine the statistical difference between control and study groups. Results: There was significant decrease in anxiety state and perceived stress with yoga intervention. Heart rate variability revealed that SDNN, RMSSD, Mean HR were significantly higher and LF, LF/HF ratio were significantly reduced after one month practice of yoga showing a shift towards parasympathetic dominance. Conclusions: Integrated yoga intervention showed significantly decreases in state anxiety and perceived stress, and a shift towards parasympathetic dominance in heart rate variability. However, the anxiety trait didn’t show significant improvement.
Experimental Results for the Multipath Performance of Galileo Signals Transmitted by GIOVE-A Satellite

Analysis of GIOVE-A signals is an important part of the in-orbit validation phase of the Galileo program. GIOVE-A transmits the ranging signals using all the code modulations currently foreseen for the future Galileo and provides a foretaste of their performance in real-life applications. Due to the use of advanced code modulations, the ranging signals of Galileo provide significant improvement of the multipath performance as compared to current GPS. In this paper, we summarize the results of about 1.5 years of observations using the data from four antenna sites. The analysis of the elevation dependence of averaged multipath errors and the multipath time series for static data indicate significant suppression of long-range multipath by the best Galileo codes. The E5AltBOC signal is confirmed to be a multipath suppression champion for all the data sets. According to the results of the observations, the Galileo signals can be classified into 3 groups: high-performance (E5AltBOC, L1A, E6A), medium-performance (E6BC, E5a, E5b) and an L1BC signal, which has the lowest performance among Galileo signals, but is still better than GPS-CA. The car tests have demonstrated that for kinematic multipath the intersignal differences are a lot less pronounced. The phase multipath performance is also discussed.
Facial emotion processing in young people with subjective memory complaints: an ERP study

Subjective memory complaints (SMCs) are commonly related to aging, but they are also presented by young adults. Their neurophysiological mechanisms are not thoroughly understood, although some aspects related to affective state have been mentioned. Here, we investigated whether facial emotion processing is different in young people with (n = 41) and without SMCs (n = 39) who were exposed to positive, negative, and neutral faces, by recording the event-related potential (ERP) activity. From the ERP activity, the N170 (an index of face processing) and the LPP (an index of motivated attention) components were extracted. Regarding N170, results showed less amplitude for positive and neutral faces in the participants with SMCs than in those without SMCs. Moreover, women with SMCs displayed longer latencies for neutral faces than women without SMCs. No significant differences were found between the groups in the LPP component. Together, our findings suggest deficits in an early stage of facial emotion processing in young people with SMCs, and they emphasize the importance of further examining affective dimensions.
Influence of Demographic Characteristics on Subjective Well-Being of Older Adults

Research into well-being of older adults is at advanced stage the world over. Most of the studies are conducted in the west. A few studies done in Kenya have focused on older adults’ abuse and vulnerability. Furthermore, these studies have used younger populations, thus lack self-reporting by the older adults themselves. This causal-comparative study sought to determine the level of subjective well-being of older adults and how demographic data related to the population and within groups influence the subjective well-being of older adults. Data was collected from older persons (n=140, >65yrs) participating in the Older Person’s Cash Transfer programme that serves the non-pensionable and aged Kenyans. Findings revealed that the older adults experienced low levels of subjective well-being, low levels of positive affect and low levels of negative affect and were dissatisfied with their life. The findings further revealed that being married, having own source of income, attaining secondary school education and poor self-perceived health, significantly influenced subjective well-being. Relative absence of negative affect strongly predicted subjective well-being, followed by presence of positive affect and finally the dimension of satisfaction with life. The demographic characteristics did not reveal themselves as predictive variables in this study. Understanding the dynamics, emotional and cognitive processes of older adults may be useful in designing interventions, strategies and policy programs that could enhance subjective well-being of older adults.
A Graphical Solution to Estimate Potential Runoff in Center-Pivot Irrigation

This article describes a mathematical model for computing the potential runoff (RUNp) in center-pivot irrigation based on curvilinear regression analysis. The RUNp is related to the water depth application (WDP) and to the maximum water depth (WDPmx) that can be applied to the soil before runoff occurs. Furthermore, using a simple three-axis graphical tool, the RUNp-WDP-WDPmx relationship was also attained. The WDPmx was determined by solving an equation incorporating the peak water application rate (a center-pivot design parameter) and two physical parameters associated with the Green-Ampt infiltration model: the effective matric potential and the saturated hydraulic conductivity. From this study, using field data from irrigation events of several center pivots, selected with different lengths and sprinkler configurations, it was concluded that the proposed graphical solution is a reasonable and easy way to estimate potential runoff. The model reliability in predicting runoff was confirmed by calculating the basic model performance statistics.
An Alternative Approach to Case-Based Learning: The Use of Student-Authored Cases

This study explores the use of student-authored cases in Case-Based Learning (CBL). While traditional CBL leads to many important learning outcomes, additional benefits may be realized with the use of student-authored cases. This study compares the effects of using student-authored cases versus traditional CBL in a computer programming course in China. The findings suggest that the student-authored case approach led to better understanding of course concepts, problem solving, and course performance compared to the traditional CBL approach. Thus, instructors might consider the use of student-authored cases a viable alternative to implementing case-based learning.
Factor Analytic Approach to Incorporating Systematic Taste Variation into Models of Residential Location Choice

In the development of residential location choice models, multicollinearity among measures of socioeconomic status and family status prohibits the inclusion of a large number of these attributes in a single specification. Alternative methods of representing these attributes with a smaller number of summary or representative measures are tested. Factor analysis is performed on the census tract–level family status and socioeconomic status variables to produce factor scores that are used in residential location choice models. The factor analysis results are also used to select one representative socioeconomic status variable and one representative family status variable to be used in choice models. These approaches are tested against a base model that uses a full set of 11 attributes. To incorporate systematic taste variation, the factors and representative variables are interacted with individual household income and life-cycle characteristics. The factor analysis approach provides a clearer interpretation of the influence of socioeconomic status and family status than inclusion of multiple variables, which obtains many nonsignificant and counterintuitive parameters. The factor scores are preferred over the use of a single representative variable, which is not readily interpreted with respect to impact of the variables it represents.
Complementary use of organic and oxide semiconductors

Complementary use of p-type organic and n-type oxide semiconductors is presented. First, we demonstrated complementary circuits using low-voltage operating high performance pentacene and amorphous InGaZnO (a-IGZO) thin-film transistors (TFTs). The field-effect mobilities of the pentacene and a-IGZO transistors are 0.6 and 17.1 cm2/V s, respectively at an operating voltage of 10 V. A complementary inverter composed of these transistors exhibits good voltage transfer characteristics with a high gain of ~56. A five-stage ring oscillator with the inverters yields an output frequency of 200 Hz at 10 V, corresponding to a propagation delay of 1 ms. Second, together with the electrical device, we demonstrated an optoelectronic device, light-emitting diodes (LEDs), using organic/oxide hybrid junctions. The hybrid p-n junction LEDs are composed of N,N'-diphenyl-N,N'-bis(1-naphthyl)-1,1'-biphenyl-4,4'-diamine (α-NPD) and sputtered ZnO. Similar with conventional p-n junction diodes, the hybrid junction shows a good current rectification and electroluminescence (EL) under forward bias. We found that the EL bands from the device agree well with the photoluminescence peaks from α-NPD and ZnO, implying the radiative recombination of injected charges occurs in both components of the junction.
Laser And Millimeter-Wave Backscatter Of Transmission Cables

Radar cross sections (RCS) of power line cables were calculated and measured at four mm-wave frequencies (18, 34, 56, and 94 GHz) and two laser wavelengths (10.6 and 1.06 pm) as a function of aspect angle. Three polarizations were considered: horizontal (HH), vertical (VV), and cross polarization (HV). Dry and wet cable conditions were simulated, and differing roughnesses were considered. The calculated and measured results are presented in this paper.
Inelastic Displacement Response of RC Systems with Cyclic Deterioration—An Energy Approach

Inelastic displacements of reinforced concrete systems are investigated by employing an energy-based approach. A hysteresis model is developed that accounts for stiffness degradation, strength deterioration and pinching. The model is calibrated by using experimental data from literature. Inelastic displacement ratios are calculated under a specific set of ground motion records with long effective durations. The results reveal the importance of deteriorating behavior under long duration excitations, especially for short and medium period structures. The last part of the study is devoted to the introduction of a simple empirical relationship for estimating the inelastic displacement demands of degrading RC structural systems.
A QBO Cookbook: Sensitivity of the Quasi‐Biennial Oscillation to Resolution, Resolved Waves, and Parameterized Gravity Waves

An intermediate complexity moist general circulation model is used to investigate the sensitivity of the quasi‐biennial oscillation (QBO) to resolution, diffusion, tropical tropospheric waves, and parameterized gravity waves. Finer horizontal resolution is shown to lead to a shorter period, while finer vertical resolution is shown to lead to a longer period and to a larger amplitude in the lowermost stratosphere. More scale‐selective diffusion leads to a faster and stronger QBO, while enhancing the sources of tropospheric stationary wave activity leads to a weaker QBO. In terms of parameterized gravity waves, broadening the spectral width of the source function leads to a longer period and a stronger amplitude although the amplitude effect saturates in the mid‐stratosphere when the half‐width exceeds ∼25 m/s. A stronger gravity wave source stress leads to a faster and stronger QBO, and a higher gravity wave launch level leads to a stronger QBO. All of these sensitivities are shown to result from their impact on the resultant wave‐driven momentum torque in the tropical stratosphere. Atmospheric models have struggled to accurately represent the QBO, particularly at moderate resolutions ideal for long climate integrations. In particular, capturing the amplitude and penetration of QBO anomalies into the lower stratosphere (which has been shown to be critical for the tropospheric impacts) has proven a challenge. The results provide a recipe to generate and/or improve the simulation of the QBO in an atmospheric model.
Evaluation of Dietary Niacin and Supplemental Cooling for Alleviation of Heat Stress in Lactating Dairy Cows

Four studies were conducted to evaluate the effects of supplemental cooling and niacin on heat stress (HS) responses in vivo and in vitro in lactating dairy cows. For experiment one, lactating dairy cows were fed four levels of dietary niacin, NIASHURE® (0,4,8,12 g/d) for 21 d. Heat stress decreased niacin levels in whole blood, red blood cells and plasma as compared to thermoneutral. Water intake, plasma and milk niacin concentrations increased linearly with increasing dietary niacin in HS cattle. In thermoneutral, but not HS cows, niacin increased skin temperature compared to controls suggesting niacin increased skin blood flow and sensible heat loss. In experiment 2, lactating cows were used to evaluate the impact of feed-line soaking (FLS) combined with niacin supplementation. In evaporative cooled barns, FLS reduced body temperatures; however the addition of niacin did not improve heat status of these cows. For experiment 3, 200 lactating dairy cows were used to determine the effects of conductively cooled bedding (CC) compared to feed-line soaking with fans (FLSF). Conductively cooled bedding can reduce skin and vaginal temperatures in cows after nighttime rest. However, FLSF were more effective in decreasing body temperature, as cows had lower heat parameter indices, higher milk yield and longer rest time. For experiment 4, three cell types were used to evaluate niacin in vitro. Niacin induced heat shock proteins (HSP) that protected cells during HS in transformed bovine mammary epithelial cells but not in primary bovine mammary epithelial cells (BMEC) or bovine endometrial cells (BEND). Effect of niacin on HSP may depend on enzymes involved in DNA-binding activity of heat shock factor 1. These results suggest that niacin may be
First records of Aspergillus porphyreostipitatus and Aspergillus carlsbadensis since their original descriptions.

During a survey of phyllosphere and non-rhizosphere soil fungi of orange plantations in the Assiut area, Egypt, several isolates of species of Aspergillus belonging to the section Usti were isolated at 25 °C. These were identified using phenotypic and genotypic characters as Aspergillus porphyreostipitatus and Aspergillus carlsbadensis. To the best of our knowledge, these are the first global records since their original descriptions and indicate their probable wide distribution. The strains of both species could grow at 37 °C (a character contrasting to that of the original description of A. carlsbadensis), but both were not able to grow on CYA at 5 °C or 45 °C or to produce acid on creatine. It is interesting to report that both strains produced the urease enzyme (however weakly in A. porphyreostipitatus) and failed to grow on G25N at 25 °C, characters not examined in the original descriptions.
The total effect on performance and energy consumption caused by office's thermal environment

Various researches highlight that indoor air quality affects performance of workers in offices. Although good indoor air quality improves work performance, it also increases energy consumption. In this study, we achieved a field survey in a real office in order to investigate the relationship between thermal environment, productivity, and energy consumption. In addition to the monitoring of indoor environmental quality and energy consumption, subjective experiments were conducted. In order to evaluate subjective performance, workers and students responded to questionnaires, and to evaluate objective performance, students simulated three types of office works. By calculating room temperature and worker's subjective performance, we demonstrate the correlation between room temperature and worker's performance (R2=0.22, p
Efeito de pontas e pressões de pulverização na deriva de glyphosate + 2,4-D em condições de campo.

The aim of the work was to evaluate the effect of nozzles and pressures on the spray drift from glyphosate + 2,4-D. The nozzles designs and the respective studied pressures were: XR 11002 (150 and 300 kPa), DG 11002 (300 kPa), TT 11002 (300 kPa), AI 11002 (300 kPa) and TXVS-10 (400 kPa). Nylon strings outside the application area (1, 5, 10, 20, 50, 100 and 200 m distance) with four replications and six foam cylinders placed on the boom of the sprayer were used to collect the spray drift. Salt tracers were added in the spray solutions to quantify the deposits of each treatment by spectrophotometer. Herbicides were less and more susceptible to drift with the flat fan nozzle with pre-orifice and air induction (AI) and the hollow cone nozzle (TX), respectively. The nozzle selection and the reduction on the spray pressures may be used to decrease drift.
The efficacy of polyunsaturated fatty acids for atherosclerotic diseases

In the field of anti-aging medicine and health science, various opinions about lipid and health are found. Among lots of clinical and epidemiological research, there has been a significant inverse association between intake of long-chain n-3 polyunsaturated fatty acids (PUFA) and atherosclerosis development [1,2]. These studies included docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), and mortality rate with coronary artery diseases. There was also the Japan EPA Lipid Intervention Study (JELIS), which showed the efficacy of reduction of major coronary events [3]. It showed a 19% reduction in major coronary events by a primary endpoint in the EPA group compared with the control group. Regarding n-3 PUFA, there have been controversies concerning the effect of arteriosclerotic diseases. Formerly, it was rather widely known that the preventive arteriosclerotic effect was present in n-3 PUFA. However, recent papers showed opposite results. This problem is related to not only medical and health matter, but also our meals in our usual lives. In this article, the problem of the effect of n-3 PUFA will be described. The results of the ASCEND (A Study of Cardiovascular Events iN Diabetes) trial were announced and noted in 2018 [4]. The prevention effect of n-3 PUFA on arteriosclerosis was investigated by Randomized Comparison Test (RCT). The result was negative, which was contrary to the clinical effects previously reported. Formerly, there was a study suggested that fish intake could reduce heart diseases [5]. Later, clinical research has been developed concerning the relationship between lipids and arteriosclerotic diseases such as heart diseases. Under these circumstances, there are two reports in 2019 from the supreme medical journal, New England Journal of Medicine. Both results were contradictory, in which one showed a preventive effect in REDUCE-IT [6], and another did not show a preventive effect (VITAL) [7]. Details of these reports will be described in the following. There is a study of the Reduction of Cardiovascular Events with Icosapent Ethyl-Intervention Trial (REDUCE-IT). REDUCE-IT was an RCT study from 473 centers in 11 countries [6,8]. The subjects included patients with established cardiovascular diseases or with diabetes and other risk factors, who had been receiving statin therapy with elevated triglyceride and/or LDL-cholesterol level. In other words, the purpose was the check for the prevention of recurrence of arteriosclerotic events. Subjects (n=8,179) were divided into two groups, which
The Description of Larva Free Index as COMBI (Communication for Behavioral Impact) Dengue Hemorrhagic Fever Prevention Indicator

Dengue hemorrhagic fever (DHF) has a high incidence rate, especially in the tropical and subtropical area. Various efforts have been made as an attempt to empower the community in PSN-dengue program, but has not yet reached the optimal result. COMBI (Communication for Behavioral Impact) is a dynamic team working to formulate and deliver the message, materials, and appropriate communication media for community problems found by way of a mutually agreed settlement of the problem.Quantitative research was done by cross sectional method to check the water storage containers inside the houses of the respondents. The number of the respondents were 990 male (38.1%), 1612 female (61.9%). Three (0.1%) respondents were aged 65 years old. Most dominant level of education and employment statuses were 1107 (42.5%) high school and 858 (32.9%) were housewives. The average numbers of Larva Free Index in Sleman Regency, Bantul Regency and Yogyakarta municipality were - 75.8%; 70.9%; and 77.3% respectively. The average CI in Yogyakarta municipality was 7.05%, Sleman Regency was 9.68%, and Bantul Regency was 20.86%. The average HI in Yogyakarta municipality was 22.7%, Sleman Regency was 24.13%, and Bantul Regency was 29.02%. This study suggested that the LFI, CI and HI were not in accordance with the target of the Ministry of Health.
Integrated Application of SPC/EPC/ICA and neural networks

There are many studies that have been conducted about the integrated use of statistical process control (SPC) and engineering process control (EPC) because using them individually cannot optimally control the manufacturing process. The majority of these studies have reported that the integrated approach has better performance than using only SPC or EPC. Among all these studies, most of them have assumed that the assignable causes of process disturbance can be effectively identified and removed by SPC techniques. However, these techniques are typically time-consuming and thus make the search hard to implement in practice. The paper discusses the development of neural network models with independent component analysis (ICA) to identify the disturbance and recognize shifts in the correlated process parameters. Moreover, these designed network models can be used to monitor and eliminate manufacturing process parameters when disturbance happens in the underlying process. For comparison, the traditional Shewhart chart and cumulative sum (CUSUM) chart, were constructed for the simulated data sets to evaluate the identifying capability of the proposed approach. As the results reveal, the proposed approach outperforms the other methods and the shift of disturbance can be identified successfully.
