Opis:
With Growing Concerns About Voltage Profile And Power Factor At Distribution Networks, The Capacitor Banks Are Invariably Installed For Reactive Power Compensation. The Reactive Power Supplied By Capacitor Banks Is Proportional To Square Of Their Rated Loading Voltage. Capacitor Banks Eventually Increase The Loading Capacity Of Feeders, So As To Supply More Customers Through Same Line Section. Capacitor Banks Can Be Installed Anywhere On The Network. The Idea Of This Paper Is To Reduce Total Power Loss And Ensure Greater Availability Of Capacitor Bank Installed At 132 Kv Grid Station Qasimabad Hyderabad, For Reactive Power Compensation, Even Under Worst Conditions On Distribution System. This Is Achieved By Enhancing Its Location And Size. At Present Capacitor Bank Of Full Size, I.E. Of 1.21 Mvar Is Installed At 11 Kv Bus Of 132 Kv Grid Station Qasimabad Hyderabad. Moreover This Paper Suggests Small Sized Capacitor Banks That Would Be Installed At Different Feeders Instead Of One Large Size Capacitor Bank At 11 Kv Bus. The Voltage Profile And Power Losses With Present Sized Capacitor Bank And The Proposed Small Sized Capacitor Banks Are Compared In This Work. The Distribution Network Has Been Simulated By Using MATLAB .

Opis:
A chelating resin based on Salicylic acid-Formaldehyde copolymer, containing Orcinol (SFO), has been synthesized and characterized on the basis of Elemental Analysis, Particle Size Distribution, FT-IR Analysis, XRD, SEM and Optical Photographs. The Physico-Chemical properties have been studied. This resin is highly stable in acidic and alkaline solutions and has been studied as a chelating sorbent for heavy metal ions and transition metal ions. The Exchange capacity order is Ni(II) > Cu(II) > Zn(II) > Cd(II) > Pb(II). The effect of nature and concentration of different electrolytes on distribution coefficient (Kd) for metal ions have been investigated. Separation of synthetic mixtures containing Cu(II)-Pb(II), Ni(II)-Cd(II) and Brass constituents has been carried out using a column prepared from the synthesized chelating resin. The developed procedure was also tested for the removal of Cd(II) and Pb(II) from natural water of Purna River near by Navsari, Gujarat, India. Keywords

Opis:
Theileriosis is a hemoparasitic disease that affects a wide range of different animal species and is caused by various species of Theileria. This study aimed to determine the molecular epidemiology of Theileria annulata through microscopy and PCR, in crossbred cattle in some districts of Khyber Pakhtunkhwa, Pakistan. For this study, a total of 384 blood samples were collected from cattle in the Peshawar (n=120), Charsadda (n=94), Nowshera (n=84), and Swabi (n=86) districts. Microscopy and PCR were used to determine the overall prevalence of theileriosis, which was found to be 15.8 and 22.6%, respectively. Theileria annulata was detected in blood samples through PCR in the study area, and the target gene i.e., Tams 1, of positive samples was sequenced. The sequences in the current study revealed high sequence homology (ranging from 96 to 100%) with Tams 1 sequences of neighboring countries present in the NCBI database. Season, breed, age, and sex were found to be important risk factors among the several risk factors examined, whereas, among different clinical manifestations, lymphadenopathy showed a strong association with theileriosis. According to Cohen’s kappa and ROC analysis, microscopy was proven to be a fair diagnostic test for detecting theileriosis in cattle, and may be used in combination with molecular techniques for screening a large number of animals.

Opis:
Plane-strain vibrations in a fluid-loaded poroelastic hollow cylinder surrounded by a fluid are investigated employing Biot’s theory of wave propagation in poroelastic media. The poroelastic hollow cylinder is homogeneous and isotropic, while the inner and outer fluids are homogeneous, isotropic and inviscid. The frequency equation of the fluid-loaded poroelastic cylinder surrounded by a fluid is obtained along with several particular cases, namely, fluid-loaded poroelastic cylinder, fluid-loaded bore, poroelastic cylinder surrounded by a fluid and poroelastic solid cylinder submerged in a fluid. The frequency equations are obtained for axially symmetric, flexural and anti-symmetric vibrations each for a pervious and an impervious surface. Nondimensional frequency for propagating modes is computed as a function of the ratio of thickness to the inner radius of the core. The results are presented graphically for two types of poroelastic cylinders and then discussed.

Opis:
Tomatoes reportedly have a positive response to seed priming. The present study evaluates the effects of ethanol priming on germination, seedling vigour and antioxidative responses of tomato seeds. Priming was achieved by exposing seeds of ‘Roma’ and ‘Nagina’ to 2, 4 and 6% aerated ethanol solutions for 24 h. Priming with low levels (2 and 4%) of ethanol improved seed germination, seedling vigour and enhanced antioxidative activity that results in better performance of tomato seeds. However, priming with 6% ethanol failed to improve seed germination and seedling development which relates to the decreased anti-oxidative activity in tomato seeds due to high ethanol level.
Uważa się, że pomidory wykazują pozytywną reakcję na pobudzanie nasion. Niniejsze badanie ocenia wpływ pobudzania etanolem na kiełkowanie, żywotność siewek oraz antyoksydacyjne reakcje nasion pomidora. Pobudzanie osiągnięto działając na nasiona odmian ‘Roma” i „Nagina” 2, 4 i 6% napowietrzonymi roztworami etanoli przez 24 godziny. Pobudzanie za pomocą niskich poziomów (2 i 4%) etanolu poprawiało kiełkowanie nasion, żywotność siewek oraz wzmagało aktywność antyoksydacyjną, która daje lepsze wyniki w odniesieniu do nasion pomidora. Jednak pobudzanie 6% etanolem nie polepszyło kiełkowania nasion ani rozwoju siewek, co ma związek z obniżoną aktywnością antyoksydacyjną u nasion pomidora ze względu na wysoki poziom etanolu.

Opis:
Umbilical hernia is one of the most common problems in young calves. This problem occurs in dairy sector as well as in the local farmers. Present study was conducted to compare outcomes of four different techniques of herniorrhaphy. Twenty four young calves (n=24) were divided in 4 groups (A, B, C, and D) which underwent four different surgical techniques. Group A underwent vicryl plus suture material and pants-over-west technique, Group B underwent mesh application with Dexon suture material by using simple interrupted suture pattern, Group C underwent closed method with Nylon No. 3 suture material by using vertical mattress suture pattern and Group D underwent clamp application method with Silk No. 2 suture material by using simple interrupted suture pattern. The result showed that mesh application method was comparatively better with respect to feed intake, body weight gain and healing time. There was no reoccurrence with non-significant hematological changes (p≤0.05). It is concluded that mesh application method is safer than other three techniques and there are no systemic effects of this surgical intervention on calves’ health.

Opis:
Early maturing peach (Prunus persica) cultivars can fetch good market value but face a lot of post-harvest problems that lead to the post-harvest losses. The 1-methylcyclopropene (1-MCP) can provide new insights into plant ethylene responses and extend the shelf life and quality of fruits. Therefore, fruits of peach cultivar ‘Early Grand’ were dipped in various concentrations of 1-MCP (0, 0.3, 0.6 and 0.9 µg l–1), stored for 40 days at 8 ±2°C with 50% relative humidity and analyzed the fruits for physicochemical attributes at 10 days interval. The highest concentration of 1-MCP at 0.9 µg l–1 significantly improved the activity of antioxidants, catalase, free radical scavenging assay and total phenols. However, the peach fruits treated with 1MCP at 0.6 µgL–1 was effective in retaining the ascorbic acid, lowering the weight loss and fruit decay. Therefore, peach fruits can be treated with 1-MCP (0.6 µg l–1) solution for prolonging its shelf life up to 40 days under low temperature.

Opis:
Meeting the educational needs of students currently requires moving toward collaborative electronic and mobile learning systems that parallel the vision of Web 2.0. However, factors such as data freedom, brokerage, interconnectivity and the Internet of Things add to a vision for Web 3.0 that will require consideration in the development of future campus-based, distance and vocational study. So, education can, in future, be expected to require deeper technological connections between students and learning environments, based on significant use of sensors, mobile devices, cloud computing and rich-media visualization. Therefore, we discuss challenges associated with such a futuristic campus context, including how learning materials and environments may be enriched by it. As an additional novel element the potential for much of that enrichment to be realized through development by students, within the curriculum, is also considered. We will conclude that much of the technology required to embrace the vision of Web 3.0 in education already exists, but that further research in key areas is required for the concept to achieve its full potential.

Opis:
Software startup companies develop innovative, software-intensive products within limited time frames and with few resources, searching for sustainable and scalable business models. Software startups are quite distinct from traditional mature software companies, but also from micro-, small-, and medium-sized enterprises, introducing new challenges relevant for software engineering research. This paper’s research agenda focuses on software engineering in startups, identifying, in particular, 70+ research questions in the areas of supporting startup engineering activities, startup evolution models and patterns, ecosystems and innovation hubs, human aspects in software startups, applying startup concepts in non-startup environments, and methodologies and theories for startup research. We connect and motivate this research agenda with past studies in software startup research, while pointing out possible future directions. While all authors of this research agenda have their main background in Software Engineering or Computer Science, their interestin software startups broadens the perspective to the challenges, but also to the opportunities that emerge from multi-disciplinary research. Our audience is therefore primarily software engineering researchers, even though we aim at stimulating collaborations and research that crosses disciplinary boundaries. We believe that with this research agenda we cover a wide spectrum of the software startup industry current needs.
