Research reviews insight into flexibility the pros and the cons of stretching prior to exercise

Flexibility is an essential fitness component that decreases with age and physical inactivity. Traditionally, including stretching especially static stretching as a warm-up has long been recommended for individuals who engage in exercise for rehabilitation, injury prevention, health improvement and athletic performance enhancement (American College of Sports Medicine [ACSM] 2006, Kovacs 2006, Shrier 2004). The proposed goals of acute stretching prior to physical activity are to enhance performance include improved coordination and proprioception, increased range of motion (ROM), reduced injury potential, improved circulation and decreased muscle viscosity, which leads to smoother muscle contractions (Fredette 2001). However, in recent years there has been growing concern about whether or not stretching should be included in the warm-up phase. Mounting evidence suggests that pre-exercise stretching plays a limited role in injury prevention and performance enhancement. Static stretching impairs performance, Static Stretches Don’t Reduce muscle Soreness, Static Stretches Don’t Warm-up Your Muscles and Static Stretches Don’t Put You in the Right State.
Life-Cycle Energy Demand of Computational Logic: From High-Performance 32 nm CPU to Ultra-Low-Power 130 nm MCU

—Given the exponential growth of the semiconductor industry, it is critical to assess the life-cycle energy demand of its products for appropriate eco-design in nanoelectronics. For computational logic applications, life-cycle energy demand is highly application dependent. In this paper, we study the life cycle of CMOS logic chips for ﬁve computational logic applications: from high-performance 32 nm CPUs for servers and laptops to low-power 45 nm processors for set-top boxes and smart phones to ultra-low-power 130 nm MCUs for RFID tags and sensors. For each chip, we model the energy demand for the CMOS processing step of integrated circuit manufacturing as well as for their use phase including both active and stand-by modes. While use-phase energy in active mode is almost two orders of magnitude higher than CMOS processing energy for high-performance CPUs, the energy demand for ultra-low-power MCUs is completely dominated by CMOS processing energy.
Factors Affecting Milk Yield Estimated with Different Methods in Brown Swiss Cattle

The aim of this study was to determine the effects of some environmental factors on milk yield levels that were estimated with different methods in Brown Swiss cattle raised in Altinova Farm. Study was carried out under similar feeding and management program. The effects of lactation turn, year and season were analysed in terms of measurable environmental factors. The data was statistically analyzed by means of the least-square method for the determination of the effects of environmental factors and by contrast-test (GLM procedure). Lactation milk yield (6294.7 kg, 6320.8 kg, 6313.9 kg) and 305 day milk yield (5927.1 kg, 6016.2 kg and 6047.5 kg) were estimated by Dutch (Holland), Swedish and Trapez methods in Brown Swiss cattle. The effects of lactation turn, year and season on lactation milk yield and 305 day milk yield were found as statistically significant (P<0.001).
Xylem diameter changes as an indicator of stand-level evapo-transpiration

Xylem diameters of living trees change diurnally. According to the cohesion-tension theory these changes result from changes in sapwood water content. A model based on the assumptions of that theory was used to predict diameter changes from the water vapour exchange in a boreal Scots pine forest. The total evapo-transpiration was measured with the eddy-covariance technique and the contribution of the understorey with open chambers together with the monitoring of the soil water content by the Time-Domain Reflectometry (TDR) method. Comparisons between measured and calculated xylem diameter changes are presented and discussed. The results reveal that diameter changes follow quite well the water vapour exchange in the cases when there was no rain.
Egg quality and age of laying hens: implications for product safety

Eggs were collected from commercial caged layer flocks in early, mid, late and very late lay. Eggs were candled and scored for translucency. Cuticle cover was estimated using MST Cuticle Stain and a Konica Minolta hand-held spectrophotometer. Traditional measures of egg quality were determined using specialised equipment. Shell ultrastructural features were scored following plasma ashing of shell samples and viewing under a benchtop scanning electron microscope. Translucency score was significantly higher in late lay than for all other age groups. Shell quality declined with increasing flock age. However, the extent of cuticle cover on the egg shell was not significantly different among flock age groups. The incidence of shell ultrastructural features associated with good quality shells was lower for older flocks and incidence of ultrastructural features associated with poorer quality shells was higher for older flocks. Translucency score had a low correlation with the ultrastructural features of the mammillary layer.
The Comparison of Outcomes and Postoperative Side Effects of Partial and Total Sphincterotomy in Patients With Anal Fissure

Background and Objectives: Endometrial hyperplasia (EH) is an abnormal overgrowth of endometrium that may l ad to endometrial cancer, especially when accompanied by atypia. Th treatment of EH is challenging, and p evious studies report conflicting results. etformin (dimethyl biguanide) is n anti-diab tic and insulin sensitizer gent, which i supposed to have antiproliferative a d nticancer effects and the pot ntial to decrease cell growth in endometrium. While some studies have evaluated the anticancer effect of metformin, studies on its potential effect on endometrial hyperplasia are rare. To address this gap, in this comparative trial study, we evaluate the effect of additive metformin to progesterone in patients with EH. Method : In this clinical trial, 64 women with EH were randomized in tw groups. The progesterone-alone group received progesterone 20 mg daily (14 d ys/month, from the 14th menstrual day) based on the type of hyperplasia, and the progesterone-metformin group received metformin 1000 mg/day for 3 months in addition to progesterone. Duration of bleeding, hyperplasia, body mass index (BMI), and blood sugar (BS) of the patients were then compared between the two groups. Findings: NA mean age of 44.5 years, mean BMI of 29 kg/m2 and mean duration of bleeding of 8 days were calculated for the study sample. There was no significant difference in age, BMI, gravidity, bleeding duration, and duration of disease at baseline between the two groups. While all patients in the progesterone-metformin group showed bleeding and hyperplasia improvement, only 69% of the progesterone-alone patients showed such an improvement, with the difference between the two groups being significant (P = 0.001). Although the difference between two groups in the post treatment endometrial thickness was not significant (P = 0.55), post treatment BMI in the progesterone-metformin group was significantly lower than in the progesterone-alone group (P = 0.01). In addition, the BS reduction in the progesterone-metformin group was significantly larger than that in the progesterone-alone group (P = 0.001). Conclusions: Our results indicated that administration of progesterone 20 mg/day plus metformin 1000 mg/day can significantly decrease bleeding duration, hyperplasia, BMI and BS in women with EH.

Household Food Insecurity and Associated Factors among Households in Sodo Town, 2015

The aim of the study: To assess the level of household food insecurity and associated factors among households in Sodo town, South Ethiopia. Methodology: A community based cross-sectional study was conducted in Sodo town from August 6up to 31, 2015. A total of 609 households were selected from Sodo town by using multistage cluster sampling technique. The data were collected using pretested and structured questionnaires based on interview with household heads. The questionnaires included socio- demographic, socioeconomic and household food insecurity access scale questions. Data analysis was done using SPSS version 16 software and both Bivariate and multivariable logistic regression analyses. Results: From a total of 609 households included in this study, 37.6 %( 95%CI =33.5%-41.5%) were food insecure. Of these 10.8% (95%CI=8.4%-13.3%) households were mildly food insecure, while 23.2% (95%CI=19.9%-26.6%) and 3.6% (95%CI=2.3%-5.1%) households were moderately and severely food insecure respectively. Factors associated with food insecurity were single household head (AOR=4.06, 95%CI=1.24-13.27), more than two dependent members in the family (AOR=3.03, 95%CI=1.38- 6.63), daily laborers of household head (AOR=16.0 95%CI =4.57-56.03) higher monthly income (AOR= 0.013, 95 %CI =0.004- 0.05) and low monthly food expenditure (AOR=10.56, 95% CI = 2.61-42.71). Conclusion and recommendation: The study shows that the prevalence of food insecurity was high in the study area as compared to urban national level. Being single household head, more than two dependent members in the household, daily laborers of household head, higher monthly income and low monthly food expenditure were significantly associated with household food insecurity. Therefore, the result needs attention on stabilization of food markets, designing urban food insecurity strategies and creating job opportunity to improving food security conditions in the studied area.

Environmental dependence of polycyclic aromatic hydrocarbon emission at z ~ 0.8 - Investigation by observing RX J0152.7-1357 with AKARI

We study the environmental dependence of the strength of polycyclic aromatic hydrocarbon (PAH) emission by AKARI observations of RX J0152.7-1357, a galaxy cluster at z=0.84. PAH emission reflects the physical conditions of galaxies and dominates 8 um luminosity (L8), which can directly be measured with the L15 band of AKARI. L8 to infrared luminosity (LIR) ratio is used as a tracer of the PAH strength. Both photometric and spectroscopic redshifts are applied to identify the cluster members. The L15-band-detected galaxies tend to reside in the outskirt of the cluster and have optically green colour, R-z'~ 1.2. We find no clear difference of the L8/LIR behaviour of galaxies in field and cluster environment. The L8/LIR of cluster galaxies decreases with specific-star-formation rate divided by that of main-sequence galaxies, and with LIR, consistent with the results for field galaxies. The relation between L8/LIR and LIR is between those at z=0 and z=2 in the literature. Our data also shows that starburst galaxies, which have lower L8/LIR than main-sequence, are located only in the outskirt of the cluster. All these findings extend previous studies, indicating that environment affects only the fraction of galaxy types and does not affect the L8/LIR behaviour of star-forming galaxies.
Burden of Care on Caregivers of Children infected with Human Immunodeficiency Virus in Calabar, Nigeria

Approximately 120,000 children died due to AIDS-related illnesses in 2016. This equates to 328 deaths every day [1]. An estimated 13.4 million children and adolescents (0-17 years) worldwide had lost one or both parents to AIDS as of 2015. More than 80% of these children (10.9 million) live in sub-Saharan Africa [2]. In addition, millions more children are indirectly affected by the impact of the HIV epidemic on their families and communities [3].
The Contribution of Instructor, Peer and University Support for Promoting Psychological Well-Being among Students in the Amhara Regional Universities

Success in higher education is most commonly indexed in Ethiopia with academic success despite the fact that the major factor undergirding this success appears to be non-academic in nature. The main intent of this study was to examine one of these academic profiles of university students (i.e., psychological wellbeing) and the extent to which it was affected by perceived (university, peer group and instructors) support services. Data were collected from a sample of 384 students (217 males and 167 females) drawn from three universities (Bahir Dar, Wollo, and Debre Tabor) in the Amhara Regional State. Structured questionnaire composed of various components originally developed by experts in the field was used for the present study; in fact after validating the sub scales. Findings indicated that psychological wellbeing general score, ‘environmental mastery’, ‘purpose in life’, and ‘self-acceptance’ were lower compared to autonomy, personal growth, and relationship with others. Female students and those from lower family income group were more vulnerable than their counterparts unlike grade level in which, contrary to previous research, little differences were noted in psychological well-being among students of different university grade levels. It was also found that university support, teacher support, and peer support were perceived to be lower. Yet, peer support and teacher support were found to be significant predictors of psychological well-being compared to university support that proved to be less useful. The results were discussed and recommendations were forwarded to fill in the gaps noted.

Employee Work Engagement: Understanding the Role of Job Characteristics and Employee Characteristics

This study was aimed to examine the effects of perceived work design characteristics and employee characteristics on employee work engagement. Drawing upon the Extended Work Design Model, this study was intended to examine the effects of five dimensions of work design characteristics (autonomy, feedback, task significance, social support and physical demand) and two dimensions of employee characteristics (self efficacy and conscientiousness personality) on employee work engagement. The respondents of this study consists of 428 nurses working in two government hospitals in Malaysia. A hierarchical multiple regression results indicated a significant relationship between autonomy, feedback, task significance, social support and self efficacy with work engagement. Theoretical and practical implications, limitations of the study and the directions for future research were discussed.
THE INFLUENCE OF ENTREPRENEURIAL ORIENTATION AND LEARNING ORIENTATION ON FIRM PERFORMANCE OF MSMES IN WEST SUMATRA

Previous studies consider different effect of relationship among EO, its antecendents and consequences. Investigation EO in a variety context such as different regions, cultures, economies and environments becomes a research priority to fully understand the nature and role of entrepreneurship. A majority study conducted in Small Medium Enterprises (SMEs) in developed countries with in western environment. This paper therefore, considers the effect of entrepreneurial orientation (EO), learning orientation (LO) and performance of Micro Small Medium Enterpises (MSMEs) in Indonesia. A quantitative approach is used to test three hypotheses. Empirical survey data collected from 144 owners of embroidery firms located in West Sumatera. Partial least square is employed to test the direct and indirect effects of EO and LO on firm performance. The paper provides evidence that EO is associated with LO and firm performance. In addition the result indicates LO is associated with performance. This research also suggests the relationship between EO and performace is mediated by LO. Regarding improving the performance, owners are suggested to implement EO and LO.
Neuropsychological Outcome After Temporal Lobe Epilepsy Surgery in Patients With Postoperative Seizures following Unsuccessful Surgical Therapy

Background: About 20-30% of patients with intractable partial epilepsy have less than favorable outcome after temporal lobectomy. This study explored the neuropsychological outcome of such surgery in this group of patients. Methods: The Medical records of patients with intractable temporal lobe epilepsy who underwent temporal lobectomy were reviewed. All patients had detailed phase I presurgical evaluation and subsequently had surgery. Detailed neuropsychology assessment was carried out in all patients pre-operatively as well as between 3 and 12 months following surgery, 13 patients with Engel class 3 outcome were included in the study. Results: There was no significant difference in the pre and post surgical IQ, verbal and visual-spatial memory performance. However, 76.9% of the patients improved in attention/executive function, 62.6% improved in language function and 88.6% improved in psycho-emotional function. Conclusions: Despite suboptimal epilepsy surgery outcome, this study demonstrates that attention /executive function, language, and psycho-emotional function improved substantially in this sample of patients. doi: http://dx.doi. org/10.4021/jnr149w
Seasonality of hydrological model spin-up time: a case study using the Xinanjiang model

Abstract. The internal adjustment process of a hydrological model followed by an unusual initial condition is known as the model spin-up. And the time required for a complete adjustment is termed as the model spin-up time. Model results for the duration of this spin-up progression are greatly impacted by the initial conditions, and often impractical or erroneous. The speed of this adjustment process is affected by the characteristics of the input data sets and their persistence. This study discusses the variability and seasonality of hydrological model spin-up time against the aridity of the river basin using multi-year climatologies for 18 river basins distributed relatively snow-free regions of the USA. The Xinanjiang model was run with each of all available year input data sets with two extreme initial conditions (saturated and unsaturated) and thereafter detected the model equilibrium state based on the Mahalanobis distance between the soil moisture states of two model runs. The seasonality of model spin-up was investigated by conducting multiple simulations that start from different time of a year. The basin average soil moisture memory (SMM) timescale (Rahman et al., 2015) and basin aridity index was estimated and thereafter investigated their relationship with the average model spin-up time. Analysis suggests that the spin-up time highly varies with the simulation starting time and the dryness of the river basin. Overall, in all basins, model achieves the equilibrium state quickly while the simulation starts in late autumn (October–November). On the other hand, model equilibrates slowly while simulation starts in spring (March–May). Wet basin shows stronger variability of the model spin-up time (mean range 154 days) throughout the year as compared with that of dry basins (mean range 78 days). The mean spin-up time is shorter for wet basins (154 days) and longer for dry basins (233 days). The spin-up times are 3–7 times longer than the SMM timescale. The basin-wise mean spin-up time shows linear and exponential relationship with the SMM timescale and the basin aridity index respectively. The relationship offers predictability of model spin-up time from widely available potential evaporation and precipitation data sets.
Stress Induced Status Of Blood Ammonia And Blood Urea With Reference To Hepatic Glutamate Dehydrogenase In Freshwater Fish, Labeo rohita.

Ammonia, being highly toxic and readily soluble in water, is excreted by aquatic animals like fishes. However, scarcity of water in the surrounding medium, may force the fishes to convert ammonia into urea. In the present study, the possible role of ureogenesis to avoid accumulation of toxic ammonia under water-restricted condition was tested in Labeo rohita. Blood urea and ammonia were estimated in the blood of the fishes and glutamate dehydrogenase acitivity was measured in the hepatic tissue. From the present study, however, it is found that the relationship between blood ammonia and blood urea in Labeo rohita and the possible role of glutamate dehydrogenase is not so pronounced in the experimental fish species.
Gamma Radiation from PSR B1055–52

The telescopes on the Compton Gamma Ray Observatory (CGRO) have observed PSR B1055-52 a number of times between 1991 and 1998. From these data a more detailed picture of the gamma radiation from this source has been developed, showing several characteristics that distinguish this pulsar: the light curve is complex; there is no detectable unpulsed emission; the energy spectrum is flat, with no evidence of a sharp high-energy cutoff up to greater than 4 GeV. Comparisons of the gamma-ray data with observations at longer wavelengths show that no two of the known gamma-ray pulsars have quite the same characteristics; this diversity makes interpretation in terms of theoretical models difficult.
