Influence of electrical and thermal ageing on the mineral insulating oil performance for power transformer applications

In the present work, a new electrothermal combined stress test cell has been designed and fabricated to conduct accelerated electrothermal ageing. The fabricated test cell includes all possible real working conditions of the transformers. The effects of accelerated electrothermal ageing on the performance of power transformers with thermally upgraded Kraft (TUK), Nomex-910 and Nomex-410 solid dielectrics in conjunction with mineral oil have been investigated. The accelerated electrothermal ageing has been performed for a temperature range of 100°C to 220°C, along with 10 kV electrical stress. Subsequently, several electrical, thermal, mechanical and chemical properties of transformer oil and different paper dielectrics have been determined. It has been observed from the diagnostic test results that Nomex impregnated mineral oil samples have better electrothermal performance as well as oxidation stability when compared to the thermally upgraded Kraft oil samples. Therefore, Nomex insulating materials in conjunction with mineral oil are suggested as alternative solid dielectrics for power transformers in order to achieve better oxidation stability, improved thermal performance for long service runs and reduced operating and maintenance costs. It is envisioned that the present experimental study will be very beneficial to utility managers and end-users of power transformers.
Clostridium Difficile Infection in Patients Impact Suspected Cytomegalovirus Infection in Patients with Inflammatory Bowel Disease

Introduction: Clostridium difficile infection (CDI) has been reported to be a cause of flare-ups in patients with inflammatory bowel disease (IBD). Cytomegalovirus (CMV) infection can cause severe disease and complications in immunocompromised patients in consequence of disease or therapy. Aim: Our aim was to describe the prevalence and clinical outcomes of CDI with concomitant CMV infection in IBD patients hospitalized for flare-ups in association with the disease itself and medication used. Methods: We prospectively identified consecutive patients referred for CDI management during 2015-2017. Stool samples were tested for Clostridium difficile toxin A and/or B and Glutamate Dehydrogenase in patients with clinical symptoms. CDI patients with IBD history were tested for anti-CMV IgG and IgM antibodies by chemiluminescent microparticle immunoassay and underwent histological analysis for CMV on colon biopsies. Data were collected for demographic characteristics, treatment and outcome. Results: 125 patients with CDI were enrolled. Among these patients, 14 (11.2%) were diagnosed with IBD. The mean patient age of IBD patients was 52.5±15.4 years at diagnosis of CDI, 85.7% had UC, 14.3% CD, while the age of patients was shared. Eleven of the total of 14 patients (78.6%) tested positive for anti-CMV IgG. Of these, 3 patients (21.4%) exhibited high CMV IgG avidity, without detectable anti-CMV IgM and biopsy-proven CMV colitis. Of the 14 IBD patients with CDI, 8 patients (57.1%) were receiving anti-tumor necrosis factor (anti-TNF) therapy (21.4 % infliximab or golimumab, 7.1% vedolizumab or adalimumab) and 43.5% of patients were being treated with systemic corticosteroids. Four UC patients (28.6%) on steroids of the 14 CDI patients underwent a colectomy whereas none of the not on steroids patients underwent colectomy (p=0.25). Among them, 1 patient (7.1%) had recurrent CDI after 5 months from the first episode of CDI.These patients were treated with vancomycin, metronidazole and fidaxomicin. The mean age of patients that had a colectomy 65.5±9.32 (n=4) was higher than the mean age of those 47.30±14.49 (n=10) who improved (UMann-Whitney=6. p=0.04). Conclusions: Immunosuppressive medications and older age are associated with increased risk of CDI and poor outcome. Although, CMV is a rare colonic pathogen in the immunocompetent patient, it should be included and screened when exacerbation of IBD occurs in patients receiving any type of immunosuppressive therapy.
Antimicrobial Properties of Cold-Tolerant Eucalyptus Species against Phytopathogenic Fungi and Food-Borne Bacterial Pathogens

Mechanol extracts of three cold-tolerant eucalyptus trees-Eucalyptus darlympleana, E. gunnii and E. unigera were screened for antimicrobial activity against twenty two phyto-pathogenic fungi and six food-borne bacterial pathogens. E. unigera showed the antagonistic activity against all the tested pathogens. Among the tested fungal pathogens, Pythium species were highly sensitive to the leaf extracts. Especially, P. vanterpoolii, a causal agent of leaf blight in creeping bentgrass (Agrostis palustris), was completely inhibited by the extracts. The eucalyptus extracts were also effective in inhibiting the fungal growth of Botrytis cinerea and Phomopsis sp. isolated from the lesions of kiwifruit soft rot during post-harvest storage. Escherichia coli O-157 was less sensitive to the inhibition than the other bacterial pathogens tested. It was likely that Gram positive bacteria-Bacillus subtilis and Streptococcus mutans were more sensitive to the eucalyptus extracts than Gram negative bacteria-Escherichia coli, Salmonella enteritidis and Pseudomonas aeruginosa. Our findings suggest that the cold-tolerant eucalyptus species have antimicrobial properties that can serve the development of novel fungitoxic agents or food preservatives.
The perspectives of professional caregivers on quality of life of persons with profound intellectual and multiple disabilities: a qualitative study

Persons with Profound Intellectual and Multiple Disabilities (PIMD) are supported by professional caregivers for a large part of their lives. However, the perspectives of professional caregivers on good or poor Quality of Live (QoL) of persons with PIMD have hardly been explored. To explore the perspective of professional caregivers on QoL of persons with PIMD, we performed a qualitative study, conducting semi-structured interviews with eleven professional caregivers and thematically analysed them. In the interviews, these professional caregivers described examples of good and poor QoL. Good QoL was mostly described in emotional terms such as happiness, pleasure and enjoying things. Poor QoL was mostly described in physical terms such as pain, sickness and shortage of breath. The capability of persons with PIMD to influence the environment was described as an element of good QoL. Furthermore, these professional caregivers described how they assessed QoL. They ‘sensed’ QoL, they tested it (trial and error) and discussed QoL of persons with PIMD with colleagues. Participants emphasized the dependency of persons with PIMD on professional caregivers. Furthermore, these professional caregivers described feelings of failure and powerlessness if they could not assess or fulfil the needs of persons with PIMD. We conclude that these professional caregivers use their (tacit) knowledge to understand QoL of persons with PIMD. The relationship between QoL of persons with PIMD and professional caregivers needs more investigation, because of its consequences both for the persons with PIMD and the professional caregivers.
Open‐Source Software Analysis Tool to Investigate Space Plasma Turbulence and Nonlinear DYNamics (ODYN)

We have designed and built a versatile modularized software library—ODYN—that wraps a comprehensive set of advanced data analysis methods meant to facilitate the study of turbulence, nonlinear dynamics, and complexity in space plasmas. The Python programming language is used for the algorithmic implementation of models and methods devised to understand fundamental phenomena of space plasma physics like elements of spectral analysis, probability distribution functions and their moments, multifractal analysis, or information theory. ODYN is an open‐source software analysis tool and freely available to any user interested in turbulence and nonlinear dynamics analysis and provides a tool to perform automatic analysis on large collections of space measurements, in situ or simulations, a feature that distinguishes ODYN from other similar software. A user‐friendly configurator is provided, which allows customization of key parameters of the analysis methods, most useful for nonprogrammers.

Agriculture History and Policy

The ancient Fertile Crescent in particular, is commonly comprehended as the origin of agriculture. The location of Western Asia covers the area of Mesopotamia and the Levant, and is limited by Syrian Desert to the south and the Anatolian Plateau to the north. First of all, a good diagnosis is needed to treat the disease, it is necessary to make a good diagnosis and definition for our sectors such as agriculture which connects our past, current and future life. In the agricultural sector, like other sectors, if we ask for a timely diagnosis and treatment of issues; certainly, we don't have to demand more because of neglect. The basis of the agricultural sector also is a science. World population has been growing and natural resources such as land and water is already under stress. To make a nation healthy and to meet food demand along with nutrition security, agriculture would continue remain as the top most priority sector for any country. Agriculture provides food, fibre and raw materials to industry. It contributes significantly to Gross Domestic Product (GDP). Agriculture provides cleaner, better environment for people to lead healthy life on earth. Moreover, it provides employment to large section of the people. If a nation has to be strong, then it has to be self-reliant coupled with strong agricultural economy that supports ecological and nutritional security. The history of agriculture has showed an important value in human development. More than half of all human around the World once efforted in farming, and even today, few—if any—humans could survive without it.This paper depicts the agricultural history and policy reforms and structural changes in World from past to the current times.
An Event Study of Simultaneous Earthward and Tailward Reconnection Exhaust Flows in the Earth's Midtail

We report an event of two‐satellite measurements of simultaneous earthward and tailward fast flows of ~500 km/s in the midtail at X ~ −63 RE and evaluate magnetic reconnection as a responsible mechanism by comparing the observations with a particle‐in‐cell (PIC) simulation. The two satellites were near midnight separated mainly along the X direction by ~5 RE. As they moved across the current sheet from the northern to southern lobes, the one closer to the Earth crossed the x line with fast flows changing from tailward to earthward, while the other one simultaneously observed tailward flows. The observed plasma and fields showed several key reconnection signatures, including the Walén relation, the fast reconnection rate of ~0.1, the Hall magnetic and electric fields, and counterstreaming electrons in the separatrix, indicating the fast flow was the reconnection exhaust. The observed temporal variations of flow speeds and magnetic fields suggested that the x line was moving tailward to a location between the two satellites and the exhaust was moving up and down. Within the exhaust, plasma pressure was highly anisotropic, and the current sheet can be unstable to the mirror, ion cyclotron, and firehose instabilities. Current sheet flapping and enhanced compressional waves near proton's local gyro frequencies were observed around the current sheet. Comparing with the PIC simulation suggests that the waves were mainly a result of oblique firehose instability.
Standardization of Robotic Grafting in Bell-Pepper (Capsicum annuum L. Var. Grossum Sendt.)

Vegetable grafting has been safely adopted for the production of organic as well as environment friendly produce and diminishes uptake of undesirable agrochemical residues. In addition to the extensively recognized advantages of disease tolerance and high crop yields, grafting technology is also highly effective in ameliorating crop losses caused by adverse environmental conditions such as low soil temperature and high soil salts.
The Civic Efficacy of Charter Schools: A Literature Review

ABSTRACT With the expansion of charter schools, astoundingly limited empirical research has considered issues related to the dimensions of civic learning in these settings. This article, seeks to augment the literature by addressing the civic efficacy of charter schools. Specifically, we employ key elements of the Octagon Model to conceptualize how charter schools influence civic learning. Findings suggest that civic learning is part of the charter school ethos. School climate, teacher practices, curriculum, and civic participation opportunities play an integral role in expanding civic opportunities to those youth enrolled in charter schools. Methodological issues, however, hamper the impact these practices may have on youth enrolled in charter schools.
BOARD STRUCTURE AND BANK PERFORMANCE: EVIDENCE FROM SERBIAN BANKING SECTOR

Traditional perspective relying on agency theory is based on the assumption that the board structure, as an internal corporate governance mechanism, determines board effectiveness and, therefore, financial performance. Board size, board composition and leadership structure are distinguished as relevant variables of the board structure. Since the results of previous empirical studies are often contradictory, examining the correlation between board structural characteristics and corporate performance is a relevant research question, particularly in banking sector. In order to improve effectiveness of internal corporate governance mechanism, and consequently bank performance, the main research objective is to identify the impact of the board size and the board composition on bank performance in the Republic of Serbia using the CAMELS model. We analyze this relation using Ordinary Least Squares regression analysis on balanced panel data-set of 54 observations. The paper contributes to recent research efforts by making conclusions on the effects of board structure on bank performance, in order to define recommendations for improving performance in banking sector.
Telebanking Adoption Intentions, Actions and Subjective Norms in the Context of Sri Lankan Private Commercial Banks

Telebanking is a service provided by a bank or other financial institution, that enables customers to perform an array of financial transactions over the telephone. Telebanking offers convenience for customers while facilitating upliftment of customer service standards from the perspective of banks. Meanwhile, subjective norms refer to an individual's perception about the particular behaviour, which is influenced by the judgment of significant others. Similarly, adoption of innovative technologies, is driven by subjective norms, ease of use, behavioural intentions, among other factors. Effect of subjective norms on telebanking adoption intentions and actions, in the context of Sri Lankan private banks is being examined in this study. Respondents were the telebanking facility using students of Uwa Wellassa University. Finally, 279 duly completed questionnaires were considered for the data analysis. Theory of reasoned action used to postulate conceptual framework and dimensions of the variables were measured by five-point Lickert scale. Tests statistics of MANOVA, ANOVA with contrast tests and discriminant function analysis were used. Empirical evidence supported the significance of subjective norms towards intentions and actions on adoption of telebanking, specifying the importance of subjective norm of the friends, in particular. There were restrictions due to limitation of time and other resources and hence, future researches could be performed in different contexts with improved representation of the tele banking population of private commercial banks. Nevertheless, research findings could be used to uplift the status of self-service banking technologies promoted by commercial banks in Sri Lanka although the research has been conducted with special reference to telebanking since most of such services provides almost the similar facilities with different interfaces such as ATMs, telephones, smartphones, personal computers, tabs etc. As the results has emphasized the significance of the effect of subjective norms, commercial banks could make use of social pressure by way of focusing on influencing existing customers towards making referrals to their friends, family members and relations to canvass new customers for mutually rewarding long-term relationship. Finally, practical and theoretical contribution could be recognized by referring to research method and analysis tools given the particular context of the research.

Temperature dependence of Eurasian perch (Perca fluviatilis).

I studied the effects of temperature, pH, competition and predation on Eurasian perch (Perca fluviatilis) in 30 lakes in Norway during 1981-2001. The study lakes were situated in two different areas in southern Norway; four lakes in Aust-Agder county in southernmost Norway were explored during 1981-1984 and 26 lakes in Hedmark county in south-eastern Norway were investigated during 1992-2001. The study lakes varied considerably in pH, temperature, fish species composition, and perch abundance and size composition. In addition to field surveys, behavioural studies of perch were conducted at Karlstad University in 2006-2007. The field studies revealed that temperature affected recruitment of perch as strong year-classes of perch generally occurred in summers with high temperatures. Temperature also affected perch behaviour as indicated by the low gillnet catches (CPUE) of perch atlow temperature. This effect on CPUE was also supported by results from the aquaria experiments, where swimming and feeding activity of perch was low at low temperature. In a study of four lakes, growth was positively related to temperature in the lake with an allopatric perch population, but not in three lakes where perch occurred sympatrically with roach. pH also affected recruitment. In the four lakes in Aust-Agder, one strong year-class of perch occurred in all lakes in a year with especially high pH in spring and early summer. Adult mortality was also affected by pH, as old perch were less abundant in lakes with late spring pH=5.5-5.8 than in lakes with pH 5.8. The size and growth of adult perch were negatively affected by low pH, whereas abundance of large, potentially predatory perch was positively related to pH. The field studies indicated that roach influence perch populations. When coexisting with roach, perch were mainly littoral. In lakes where roach dominated (by number), there was no growth – temperature correlation, but there was such a correlation in lakes without roach. In lakes with sympatric roach, age-specific weight of perch and the growth of 2+ perch were negatively related to the proportion of roach in the gillnet catches. In the aquaria experiments, swimming and feeding activity of perch were lower than that of roach at all temperatures tested, and the difference was most pronounced at 4 and 8 °C. The aquaria experiments indicated that perch had a lower feeding efficiency and that they generally occupied positions closer to the bottom than roach.
