Spectroscopic Study of Arc Temperature Profiles of a Switching-off Process in a Model Chamber

A model chamber was applied to emulate a switching-off process which is very similar to those in real high-voltage circuit-breakers. The arc between moved W-Cu electrodes through a PTFE nozzle in SF6 was considered. Transparent windows in the chamber wall and a slit in the nozzle enabled an optical investigation of the arc cross section several milliseconds before current zero. The side-on radiance of fluorine atom lines has been measured. Considering rotational symmetry of the arc the corresponding radial emission coefficients have been determined. Radial temperature profiles have been obtained with uncertainties below 10% considering change of window transmission and optical depth of the line radiation. The experimentally determined temperature profiles are used to validate a CFD simulation of the switching-off process in the model chamber.
Histological isolated endarteritis benefits glomerular filtration rate and allograft survival after anti-rejection treatment

Isolate endarteritis after renal transplantation has been regarded as T cell-mediated acute rejection in Banff classification. Recently, results from DNA microarrays suggested that isolate endarteritis did not represent T cell-mediated acute rejection exactly and its effect on allograft outcomes was unclear. A total 192 cases of biopsyproved acute cellular rejection had been recorded between September 2001 to December 2014. There were 111 cases in endarteritis negative group and 81 cases in endarteritis positive group. The baseline information, serum creatinine and glomerular filtration rate (GFR) before and after anti-rejection treatment, steroid resistance, rejection reversal rate, graft survival were compared in two groups. The rejection reversal rate of endarteritis positive group was 90.1% (73/81), significantly higher than 77.5% (86/111) of endarteritis negative group (P = 0.022). GFR of endarteritis negative group was considerably higher before and at biopsy but significantly lower after biopsy compared with endarteritis positive group. The graft loss rate of endarteritis positive group was 17.3% (14/81) and 28.8% (32/111) of endarteritis negative group (P = 0.064). Although the graft survival since the time after kidney transplant was similar between two groups, the death-censored or death-uncensored survival since the time after anti-rejection treatment in endarteritis positive group was significantly higher than that in endarteritis negative group. Isolated endarteritis benefits the patients from better GFR and allograft survival after rejection treatment.
vCJD: Potential for a large epidemic-Are dental procedures aiding its spread?

The emergence of vCJD, together with the varying incubation period of prion proteins and their resistance to standard sterilisation, raises the possibility that vCJD may currently be spreading unnoticed through the population, and routine dental treatments as well as other invasive procedures may be aiding this. Transmissible spongiform encephalopathies (TSEs) are not known to spread by contact from person to person, but transmission can occur during invasive medical interventions. Exposure to infectious material through the use of human cadavericderived pituitary hormones, dural and cornea homografts and contaminated neurosurgical instruments have all caused TSEs. The current vCJD epidemic in Britain has raised many fears, as no scientist knows the current number of people infected, with estimations ranging from 60 to several million carriers. The potential for iatrogenic spread, via surgical procedures, through the population is also unknown. Few papers have been written on the potential of dentistry to spread vCJD. Epidemiological studies have not revealed any evidence that dental procedures lead to an increased risk of iatrogenic transmission of vCJD. However, experimental studies have demonstrated that animals infected by intra-peritoneal inoculation develop a significant level of infectivity in gingival and dental pulp tissues and that TSEs can be transmitted to healthy animals by exposing root canals and gingival abrasions to infectious brain homogenates. Even The World Health Organisation committee on TSEs was, “unable to come to a consensus on the risk of transmission of TSEs through major dental procedures,” showing the need for clarification on the issue. This dissertation intends to evaluate the current evidence and ideas on the vCJD epidemic, estimate the number of people that could be infected and assess the risk, if any, of these people transmitting vCJD via surgical and in particular dental procedures.
CD 8 + T cells in cutaneous leishmaniasis : The good , the bad and the ugly

CD8+ T lymphocytes are components of the adaptive immune response and play an important role in protection against many viral and bacterial infections. However, their role in parasitic infections is less well understood. In leishmaniasis, a disease caused by intracellular protozoan parasites of the genus Leishmania, CD8+ T cells have been shown to be protective. However, increasing evidence indicates that CD8+ T cells may also exacerbate disease. In this review, we will describe the situations where CD8+ T cells are either good or bad for the outcome of the infection, and attempt to reconcile the dual role played by CD8+ T cells in cutaneous leishmaniasis.
EFFECT OF INJECTION TIMING ON PERFORMANCE , COMBUSTION AND EMISSION CHARACTERISTICS OF DIESEL ENGINE USING CANOLA OIL AS FUEL

Due to the increasing demand for fossil fuels and environmental threat, a number of renewable sources of energy has been studied worldwide. An attempt is made to assess the suitability of vegetable oil for diesel engine operation. In Diesel engines quality of combustion is depending on the formation fuel-air mixture. A high-quality of formation for combustion is achieved by addition of pulverized fuel drops and the air inside the cylinder. In this issue, injection parameters such as timing and period of injection, injection pressure and the number of the injection beams affect quality of combustion and mixture formation. The present paper is focused on the effect of injection timing on performance, combustion and emission characteristics of canola biodiesel and its blends with pure diesel on a 4 stroke direct injection diesel engine without any modification in the existing experimental setup. Standard injection pressure (220 bar) is maintained during the experiment. Injection timings (21°, 24° and 27° bTDC) were considered under steady state conditions at maximum load condition of the engine. The effect of varying injection timing was evaluated in terms of thermal efficiency, specific fuel consumption, carbon monoxide, hydrocarbons and oxides of nitrogen were presented graphically and concluded that the advanced injection timing increases the brake thermal efficiency and reduces unburned hydrocarbon and Nox emissions significantly.
Pistacia weinmannifolia ameliorates cigarette smoke and lipopolysaccharide-induced pulmonary inflammation by inhibiting interleukin-8 production and NF-κB activation

Pistacia weinmannifolia (PW) has been used in traditional Chinese medicine to treat headaches, dysentery, enteritis and influenza. However, PW has not been known for treating respiratory inflammatory diseases, including chronic obstructive pulmonary disease (COPD). The present in vitro analysis confirmed that PW root extract (PWRE) exerts anti-inflammatory effects in phorbol myristate acetate- or tumor necrosis factor α (TNF-α)-stimulated human lung epithelial NCI-H292 cells by attenuating the expression of interleukin (IL)-8, IL-6 and Mucin A5 (MUC5AC), which are closely associated with the pulmonary inflammatory response in the pathogenesis of COPD. Thus, the aim of the present study was to evaluate the protective effect of PWRE on pulmonary inflammation induced by cigarette smoke (CS) and lipopoly-saccharide (LPS). Treatment with PWRE significantly reduced the quantity of neutrophils and the levels of inflammatory molecules and toxic molecules, including tumor TNF-α, IL-6, IL-8, monocyte chemoattractant protein-1, neutrophil elastase and reactive oxygen species, in the bronchoalveolar lavage fluid of mice with CS- and LPS-induced pulmonary inflammation. PWRE also attenuated the influx of inflammatory cells in the lung tissues. Furthermore, PWRE downregulated the activation of nuclear factor-κB and the expression of phosphodiesterase 4 in the lung tissues. Therefore, these findings suggest that PWRE may be a valuable adjuvant treatment for COPD.

The stress of transportation and acclimation (handling, sorting, overcrowding, physical injuries, poor water quality) are the primary contributing factors to fish diseases and mortality in aquaculture. (Wedemeyer and Yasutake, 1977) Stress is defined as any condition that causes physical or mental discomfort which either results in the release of stress related hormones (eg adrenaline) or in bringing about specific physiological responses (Okafor, 2011 , Uzebu and Mba, 2015) Long term stress or severe short term stress ,can contribute to many of the illnesses and deaths in aquarium fish. Chronic stress can lower the immune system of fish (Wedemeyer and Yasutake, 1977) There are many potential stressors of fish, but some of the common ones include: harassment by other fish, inadequate tank size which leads to overstocking of tank, inadequate nutrition, poor sanitation, lack of hiding places, injury from bigger fishes or d u r i ng h a nd l i ng ( c ap t u r e , s o r t in g , transportation) poor water quality (low dissolved oxygen, undesirable temperature, salinity and pH, increased levels of CO NH , a
Performance of Savonius Horizontal Axis Water Turbine in Free Flow Vertical Pipe as Effect of Blade Overlap

Article history: Received 20 September 2018 Received in revised form 13 December 2019 Accepted 2 April 2019 Available online 16 June 2019 Water in vertical wastewater pipes has the potential to produce electrical energy due to its big momentum force. This paper proposed a Savonius turbine as an electric generator which works efficiently at low speed and limited head. This study specifically aims to investigate the effect of the overlap ratio of the blade mounted on a 3-inch diameter pipe at a maximum head of 2m at Savonius Horizontal Axis Water Turbine (HAWT) to the coefficient of power and tip speed ratio. The optimal result of this study was obtained in the blade overlap ratio of 0.3 at every discharge. The most optimal performance occurred at the discharge of 11.9 l/s with variation of overlap, while 0.3 had the most optimal performance of 30.58 Watt power output, TSR of 0.79 and power coefficient 0.19.
PRODUCTION OF CARROT POMACE POWDER AND ITS UTILIZATION IN DEVELOPMENT OF WHEAT FLOUR COOKIES

This project was undertaken at Food Technology Section, Post Harvest Research Centre, AARI, Faisalabad, Pakistan during 2014-15 to study the production of carrot pomace powder and its utilization in cookies. Carrot pomace powder was prepared by dehydration at 60°C in tunnel dehydrator. Carrot pomace powder and wheat flour were subjected to proximate analysis like moisture content, ash, crude fat and crude fibre. Carrot pomace powder was replaced with plain wheat flour at proportion of 0, 4, 8, 12 and 16%, respectively. The prepared cookies were evaluated for proximate composition, physical parameters and sensory properties for the period of three months at 15 days intervals. It was observed that moisture content of cookies increased from 3.35 to 4.36% within the treatments and 3.78 to 4.04% during storage. Increasing trend was also observed in ash content (0.42% to 1.16%), crude fat content (21.43%-22.64%) and crude fibre content (0.2%-2.35%) within the treatments. However, decreasing trend in these parameters was observed during storage. The physical factors like width of cookies decreased from 50 to 44.65mm among treatments while a decrease in thickness from 11.93 to 10.72 mm was also noted. Resultantly the spread factor value also reduced from 46.7 to 37.3mm by adding more proportion of carrot pomace powder. With respect to storage of physical parameters of cookies, no significant variation was observed. The cookies incorporated with 12% carrot pomace powder with wheat flour scored better (8.03) with respect to overall acceptability which can be commercialized.
VOLUME 5, NUMBER 3

This paper explores the linkages between employee consciousness of the High Performance Work System (HPWS) and their commitment through a matrix approach. The impact of individual human resource practices in HPWS on employee outcomes is also investigated. The data collected came from the enquiry responses of non-managerial Japanese employees in sixteen companies in the Kanto region of Japan from around October 2008 to February 2009. The average response rate was 52% (n=227). Discriminant analysis reveals that HPWS, affective commitment and occupational commitment were the most important discriminant variables in the four predicted groups of HPWS-Commitment linkages. Hierarchical Ordinary Least Squares (OLS) regression indicates an increase in teamwork, employee participatory programs, and the sharing of company information with employees as human resource practices in HPWS that could increase employee commitment and reduce stress, though some practices could also increase job intensity. The research findings contribute to the extant literature in HPWS and employee psychology. The practical implications of the findings are also discussed.

Assessing generalization of feedforward neural networks

Neural networks have been used to tackle what might be termed 'empirical regression' problems. Given independent samples of input/output pairs (x/sub i/,y/sub i/), we wish to estimate f(x)=E[Y|X=x]. The approach taken is to choose an approximating class of networks N={/spl eta/(x;w)}w/spl isin/W and within that class, by an often complex procedure, choose an approximating network /spl eta/(/spl middot/;w*). The distance (in mean squared error) of this network from f can be separated into two terms: one for approximation or bias-choosing N large enough so that some /spl eta/(/spl middot/;w/sup 0/), say, models f well-and one for estimation or variance-how well the chosen /spl eta/(/spl middot/;w*) performs relative to /spl eta/(/spl middot/;w/sup 0/). We address the latter term.
A pr 2 01 9 A new treatment for some periodic Schrödinger operators I : the eigenvalue

We study the problem of how the Floquet property manifests for periodic Schrödinger operators which are known to have multiple of asymptotic spectral solutions. The main conclusions are made for elliptic potentials, we demonstrate that for each period of the elliptic function there is a relation about the Floquet exponent and the monodromy of wave function. Among them there are two relations not explained by the classical Floquet theory. These relations produce both old and new asymptotic solutions consistent with results already known.

Study on risk factors for depression in female infertile patients and evaluation of efficacy of psychological nursing intervention

Objective: To analyze the risk factors for depression in infertile patients on a basis of female infertile outpatients and to evaluate the efficacy of psychological interventions on depression and quality of life. Methods: The study was comprised of the following two parts: in the first part, a total of 185 patients treated from January 2015 to December 2015 were recruited as research objects and a case-control study was adopted to analyze the risk factors for depression in female infertile patients; the second part was a randomized controlled study of 160 female infertile patients treated from January 2016 to December 2016, who were categorized into regular nursing group and psychological nursing group. To compare the differences in score improvements of Self-rating Depression Scale (SDS) and The Fertility Quality of Life (FertiQoL) between the two groups at the initial visit and three months after the intervention, comprehensive psychological interventions of health education and cognitive behavioral therapy were conducted in the psychological nursing group on the basis of routine care. Results: On a univariate analysis, age, educational level, family income, the duration of infertility, causes of infertility, costs and frequencies of treatments were all possible risk factors for depression in female infertile patients. Taking the above factors into the logistic regression analysis, the study found that the longer duration of infertility, female factor infertility, the higher costs and frequencies of treatments were all independent risk factors for depression in female infertile patients and the adjusted odds ratios were 1.77 (95% confidence interval (CI): 1.18-2.29), 2.26 (95% CI: 1.43-3.24), 1.89 (95% CI: 1.21-2.44) and 2.19 (95% CI: 1.53-3.23), respectively. The score improvements of SDS and FertiQoL before and after intervention in psychological intervention group were outstandingly higher than those in the control group (all P<0.05). Conclusion: The longer duration of infertility, female factor infertility, the higher costs and frequencies of treatments will increase the risks of depression in female infertile patients. In comparison with routine care, psychological intervention can effectively alleviate the depression and improve the quality of life in patients.
The relationship between miR-106 a and bone morphogenesis proteins and its role in bone marrow mesenchymal stem cell osteogenesis differentiation

Osteoblast is the major functional cell for osteogenesisr responsible for bone matrix synthesis, secretion and mineralization. Osteoblast mainly derives from undifferentiated mesenchymal stem cells (MSCs). Osteogenesis differentiation process of MSCs is critical for human bone formation, differentiation and regeneration. This study aimed to investigate the relationship between miR-106a and bone morphogenesis, as well as its role in bone marrow MSCs osteogenesis differentiation. Percoll approach was used to separate MSCs from human bone marrow for osteogenesis differentiation induction. qRT-PCR was used to test miR-106a expression. Bioinformatics analysis was performed to predict target genes of miR-106a, followed by luciferase reporter gene assay. The effects of miR-106a on MSCs osteogenesis were analyzed. Western blot was used to analyze expression of osteogenesis differentiation related proteins including RUNX2, OCN and ALP. Cells separated by Percoll method expressed CD44 and CD25 as demonstrated by flow cytometry. MSCs showed features of osteoblast after osteogenesis differentiation induction, as miR-106a expression level was significantly suppressed (p<0.05). Bioinformatics prediction and luciferase reporter gene assay confirmed that miR-106a could suppress BMP2 gene expression. Cell transfection for inhibiting miR-106a expression facilitated MSCs osteogenesis differentiation, and significantly elevated RUNX2, OCN and ALP expression level (p<0.05 compared to control group). In conclusion, During osteogenesis differentiation of MSCs, miR-106a is down-regulated to enhance expression level of its target gene BMP2, eventually facilitating MSCs osteogenesis differentiation.
STUDIES ON SEED DORMANCY IN PADDY GENOTYPES

Paddy is the second most widely consumed cereal in the world next to wheat. It is the staple food for two thirds of the world’s population (Kumari et al. 2014). Paddy occupies a pivotal role in Indian agriculture. It is the staple food for more than 70 per cent Indians and a source of livelihood for 120-150 million rural households. It provides more than fifty per cent of daily calorie intake and considered as the cheapest source of food, energy and protein in the developing countries. India ranks second in the production of paddy; as it is grown in almost all the states in India. Total estimated area under paddy production in India is 44.40 million hectares with a production of 104.32 million tonnes. (Anon., 2012). Dormancy is problematic in agriculture as it affects plant establishment but it is the ability of the seeds to delay their germination until the time and place are right reflecting an important survival mechanism in plants. Dormancy is one mechanism by which seeds maintain their viability in unfavorable conditions. In spite of this advantage dormancy creates problems for seed analysts and seed producers, especially when the germination percentage of seed lot must be determined in a few weeks after harvesting. Sometimes even if the seeds germinate readily at harvest, due to unfavorable environmental conditions during storage or germination, secondary dormancy may develop.
