Isolation and characterization of fatty acid from peel of the pear fruit (pyrus pyrifolia) and evaluate its antioxidant activity

A fatty acid was isolated and purified from pear fruit (Pyrus pyrifolia) peel extract by using column chromatography technique and evaluated its antioxidant activity by 1, 1-diphenyl-2-picrylhydrazyl (DPPH) radical-scavenging assay and reducing power assay. The isolated compound was identified as Gadoleic acid on the basis of nuclear magnetic resonance spectroscopy and it showed the high percentage of antioxidant activity but less than the ascorbic acid. As the concentration of the compound increased the percentage of activity also increased in both the DPPH assay and reducing power assay.

The dynamics of fishing season and tuna fishing in the Indian Ocean Waters (FMA) 573

Knowledge of the existence of fish in the sea is very important to decide the right time for fishing operation. The aim of this study is to decide the right time for fishing operation in the Indian Ocean FMA 573, through 1) information about fishing season of tuna in three different waters in the Indian Ocean i.e, East Java Province, Yogyakarta Province and East Nusa Tenggara Province; and 2) information about size of tuna being caught.

MAD over donuts vs. krispy kreme: a comparative study based in the city of Mumbai

The paper analyses two enterprises in the monopolistically competitive doughnut industry in Mumbai: ‘Mad Over Donuts’ and ‘Krispy Kreme’ and their operative strategies. It concludes that while Krispy Kreme may have the better product, it has a higher price, fewer locations and not enough promotional activity.

Personality assesment through projective techniques

Personality assessment using projective techniques is aim to assess the personality of a respondents using projective techniques, in early days there were various methods used to assess the personality. Pherenology, Phsiognomy, Pelmistry and astrology were some of the pseudo-scientific methods but these methods of assessment are not at all reliable so the method were discarded. The more reliable and scientific method have been developed later and widely used method was projective techniques for assessing personality.

Assessing preference of released improved haricot beans (phaseolus vulgaris l.) by farmers in the western highlands of Cameroon

The need to increase productivity of Haricot beans and improve on the livelihood of farmers led to the introduction of improved Haricot beans with shorter life cycle, high yielding and resistant to pest and diseases. Despite these positive benefits, effective adoption has been slow as farmers remain reluctant to adopt most of these varieties. The survey, thus, focus on evaluating the production, marketing and consumption of released improved Haricot beans by farmers in the Western highlands. It also examines the socio-demographic factors that influence its adoption.

Small scale farmers’ knowledge and perceptions of maize insect pests and their management in highveld and middleveld regions of Swaziland

Farmers’ perception of insect pests and effectiveness of their management tactics are crucial in improving yields of maize. Surveys were conducted in the small scale maize farmers in Highveld and Middleveld regions of Swaziland to gain insights into farmers’ perceptions of maize pests and pest management practices. Interviews administered to 61 small scale farmers revealed households’ age, educational background and years of experience in maize farming affects farmer’s perception and pest management practices.

Radon exhalation rate and radiation dose from soil samples collected from different places surrounding the kasimpur thermal power plant

Fly ash from a thermal power plant is spread and distributed in the surrounding areas by air and may be deposited on the soil of the nearby region. Thus the radioactivity levels of the soil samples may alter and it is quite important to estimate the changes. Can technique using LR-115 type II solid state nuclear track detector has been employed for the measurement of radon activity and radon exhalation rate.  Radon activity varies from 3091.43 Bq m-3 to 4997.14 Bq m-3 with an average value of 3948.19 Bq m-3 .

The study of viral diseases in georgian vine grafted nurseries

Grapevine infections are one of the most viral diseases affecting grapevines throughout the world. The impact on vine health, crop yield and quality is difficult to assess due to a high number of variables, but significant economic losses are consistently reported over the lifespan of a vineyard if intervention strategies are not implemented. Georgia is one of the oldest wine producing regions. The main goal of the research was to study the spreading of grapevine viral diseases for further selection of virus-free material in Georgia.
