The geometry of painting landscape remains one of the long standing problems that cannot be explained theatrically. This work is devoted to use geometrical optics to explain this aspect. It utilizes eye geometry to explain why the horizon appears as an infinite line, and also explains why sky meat earth surface at a point. besides showing the reason that makes large mountains does not converge to a point far from human eye vision.   

Groundnut the “king of oilseeds” is grown on area of 4.60 million hectares with the production of 4.8 million tonnes during the year 2014-15. Among the various agronomic practices, fertilizer, weeding and plant protection play important role in maximizing the pod yield. Keeping in view all the facts, the study of performance of groundnut as influenced by resource constraints was formulated in RBD design in three replications with 8 different treatments. The results in the present investigation revealed significant differences in respect of pod yield for all the treatments studied.

Community-based tourism has, for over four decades, been promoted as a means of poverty reduction in developing countries. This study sought to investigate the social and economic effects of community-based tourism using the Wechiau Community-based Hippo Sanctuary located in the Upper West Region of Ghana. The research relied on both qualitative and quantitative approaches using household questionnaires as its primary data collection instrument. The study reveals the ever increasing tourists arrival, with its attendant revenue, as the major economic benefit of the sanctuary.

In India, women have remained as a neglected section of work force. Women are lagging behind men mainly because of the relative absence of economic opportunities and minimal participation in decision making process. Educational backwardness is another major reason why women are lagging behind men. The participation of women in professional and technical work force is low. Therefore, the organizations concerned with the development of women considered empowerment of women as a solution to these problems.

An efficient protocol has been devised for the mass in vitro propagation of Dendrobium bellatulum Rolfe, a rare miniature orchid, through immature embryos obtained from 120-d-old capsules after pollination. In vitro seed germination trials were conducted using three different basal media viz., half strength Murashige and Skoog (½ MS), and Knudson C (KC) and Vacin & Went (VW), of which ½ MS medium proved to be ideal for getting maximum percentage of seed germination, 83.97 ± 0.83% within 8 weeks.

There are numerous different approaches for measuring and improving the quality in undergraduate education. "Educational Evalution Systems" is one of the most significant one of the cited approaches. The most important components which affect the quality of education in "Educational Evaluation Systems" are considered to be the education itself, the students and the instructors. The purview of this study is limited to “instructors”, which is one of the foregoing components, with an eye to achieve more accurate results.

In present study, the in-vitro antioxidant activities of the methanolic extracts of leaves and flowers of Ipomoea cairica were determined by spectrophotometric method. Antioxidant activities of extract were expressed as percentage of DPPH radicals inhibition. The methanolic extract of Ipomoea cairica leaves showed maximum antioxidant activity of 83.52% and methanolic extract of Ipomoea cairica flowers showed maximum antioxidant activity 81.85 % at 500 μg/ml concentrations. This study reveals that leaves and flowers of I. cairica can be used as natural sources of antioxidants.

The purpose of the study is to measure the parental satisfaction on vocational rehabilitation services for adults’ with intellectual disability. A survey was carried out on a sample of 60 parents’ (42 mothers’ and 18 fathers’) of adults’ with mild, moderate and severe intellectual disability, between the age ranges of 18 to 40 years. The sample was drawn from residential and non- residential Vocational rehabilitation centers situated in the twin cities of Hyderabad and Secunderabad.

The study aims to describe the differences in quality, yield and composition of ω-3 fatty acids in fish oil, and quality microencapsule as functional materials on brownies. The research was conducted in three stages, namely extraction, testing the quality, yield and composition of ω-3 fatty acids and proximate of brownies. Analysis of quality concist of the composition of ω-3 fatty acids, yield, peroxide, anisidin, and total oxidation. Proximate data were analyzed with ANOVA and continued with HSD  at level α of 5%. The results showed that yield of the method BD is 4.05% and SP is 3.70%.

Objectives: International food safety standards having a great interest in public health and setting legislative Maximum Residue Limits (MRLs) of the host country with respect to applied agrochemicals. India is the leading country known for its highest tonnage per hector grape yield due to the favorable microclimatic conditions. Present investigation aimed to determine pesticidal residues in International and Indian wine samples using various sophisticated biophysical instrumentation.
