A variety of diseases causing agents are transmitted through ectoparasites. For the control and prevention of ectoparasitic infestations, different antiparasitic agents are used. The present study was designed to analyze the efficacy of ivermectin and fipronil in cats. For this purpose, 40 cats of different age and both sexes infested with ectoparasites were divided into four groups viz A, B, C and D. Cats of groups A, B and C were treated with ivermectin, fipronil, combination of ivermectin and fipronil, respectively, while group D served as control. At 7 th and 15 th day of post treatment, cats were examined for the presence of ectoparasites. Three milliliter of blood sample was collected before and post treatment at day 0, 7 and 15 aseptically from the jugular vein of each cat in EDTA coated vacutainers and were subjected to hematological analysis. The efficacy of insecticides was statistically analyzed and data obtained from the results. The efficacy percentage of Ivermectin was 60 and 90, fipronil, 80 and 100 while their combination showed 90 and 100 percent efficacy at the day 7 th and 15 th respectively. WBCs and RBCs were significantly higher at day 15 th for group C. While PCV and Hb concentration were higher for group B at 15 th day of study. In case of weight gain group A and C showed significant improvement over group B. It is concluded that in case of efficacy and hematology Fipronil and combination form is more effective.

Currently they are one of the leading candidates for replacing Flash memory technology as it nears its scaling limits. Despite many years of work and many encouraging demonstrations, the physical mechanism that drives the resistance switching phenomenon remains very poorly understood. A model based on migration of oxygen vacancies is often invoked, however direct proof of this model still remains illusive. In this thesis, we developed a kinetic model of oxygen vacancy migration. Using this model, simulations were carried out on a 1-D device to examine the resistance switching and retention dynamics. It is found that in order to achieve fast switching (100 ns) and long retention (10 years), the vacancy migration based model requires unrealistic electric field (>10 MV/cm) and temperature (>1500 K) combinations. This situation does not change even when non-linear dependence of vacancy velocity on electric field is taken into account. A significant portion of this thesis is focused on detailed examination of the electroforming characteristics of TiO2 based resistance switching devices. Electroforming is a step where a device is electrically stressed in order to trigger permanent changes to the oxide layer. During this process, the resistance of the device is usually lowered by 5-6 orders of magnitude. Stable resistance switching can only be obtained after performing electroforming. Most studies for this work were performed on 5 μm × 5 μm sized devices with Pt/TiO2/Pt structure. Transient pulsed method

They overlook the importance of creating a unique school vision that is tailored to their contextual requirements. Setting direction through a clear vision for the school is one of the four core leadership practices and has been extensively explored around the world. By drawing on personal reflection, this essay highlights the imperative for school principals from the regions to actively participate in developing a school vision that is contextually responsive for their school and also aligns with the guidelines of the department of education. Using three personal examples, it underscores the crucial role that visioning plays in a school's success and the indispensability of stakeholder's involvement in the visioning process.

It is resistant to the majority of chemotherapeutics and has a dismal prognosis. Hepatocellular carcinoma is a prevalent complication of chronic liver disease (CLD) in India. Primary liver cancer is the 6 th most common cancer worldwide and the 4 th most prevalent cause of cancer-related death. In 2018, it affected 841,000 people and caused 782,000 deaths around the world. Thus, research into the tumor cycle and its prevention through suitable herbal (Unani/Ayurvedic) medication is critical for reducing the impact of primary liver cancer. Treatment options for end-stage liver cancer are limited, necessitating costly liver transplantation, which is unavailable in most countries. Here, we present the results of a comprehensive literature survey to determine the benefits of using various herbs with liver protective and antioxidant properties. This information will be useful to researchers working on liver carcinoma and free radical scavenging, both of which are important in curbing potential carcinogens.

In this grounded theory study, an in-depth investigation of the ways in which six teachers from five different collectivist countries described their beliefs and classroom practices was carried out. Through the constant comparative method, the two authors grouped the findings into categories of beliefs and practices which were then examined through the lens of the six dimensions of Hofstede’s model of cultural difference. Six categories of classroom practices, Pedagogy, Interaction, Student Role, Teacher Support, Differential Assessment, and Behavioral Management and three major beliefs, Importance of Teacher-Student Relatedness, Teaching: a Social Responsibility, and Learning for Life Skills emerged from the findings. The comparison revealed a multi-dimensional structure of teachers’ practices with strong evidence of both traditional and cons...

Based on data collected through semi-structured interviews of the principal, teachers, students and parents, and observations, document scanning and field notes, the study attempts to identify the context under which the school operates, the core practices of the school principal and the enactment of these core practices. The data analysis was carried out through data reduction resulting in initial themes which were further refined several times until consensus was achieved. The themes were then discussed under the light of theories resulting in the final categories. The findings reveal that personal traits of the principal and her strength of building strong coalitions enabled her to successfully meet her contextual challenges. In conclusion, we argue that leadership practices are multidimensional and although successful principals draw from the similar repertoire of core practices, they enact these core practices in response to their own unique contexts to bring success. The findings would provide important insights for principals and future researchers who might be interested in conducting similar studies to enrich the successful school leadership literature from Malaysian context.

In the absence of similar studies conducted in Malaysia, this qualitative case study of one urban and one rural school attempts to identify the school contexts under which the two successful principals operate and how they enact their core leadership practices in response to their own contexts. The study utilizes interviews, observation notes and scanning of school documents for data collection. The principals of the two schools, three teachers, three students, three parents and one senior administrator from each of the two schools were interviewed using a semi-structured interview protocol. Both the schools were visited several times for observations, data scanning and collection of additional data from the respondents. In...

Parabolic Trough Collectors do not pollute the environment and hence can be marked as Green Technology. In this paper, a prototype of PTC is optically designed, fabricated, tested and controlled with an autonomous solar tracking system. The system is easy to install, modular and operate and maintain its primary functions under the given parameters in order to widespread and diffuse the use of solar energy. The fabricated PTC and its tracking system were tested under an open sky under hot and humid climatic conditions. The experimentation results were compared with the initial mathematical modelling and it contained significant variations due to several factors. The overall aim of the work reported in this paper was to test the performance of a solar parabolic trough collector system by raising the temperature of the working fluid above the boiling point of water and to enhance the efficiency also by reducing the cost of the heat produced.
