This research focus on the formulation, development and testing a new additive in synthetic based drilling fluid include of amine-treated Quebracho agent . Traditionally invert emulsion drilling fluids have been formulated to achieve optimum performance of drilling operation because of the high level of wellbore stability and penetration rates by these drilling fluids. Amine-treated Quebracho agent is compatible with other chemical additives in Synthetic-Based Fluids.

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.

The paper analyses two enterprises in the monopolistically competitive doughnut industry in Mumbai: ‘Mad Over Donuts’ and ‘Krispy Kreme’ and their operative strategies.

The population in this research was the whole community that settled in the region of watershed Mamasa. They Consist of 16 700 head of family. The numbers of samples in the study were 340 head of the family. In this study variables Consist of independent variables namely Subjektive Norms (SN) has a relationship with the dependent variable Behavior (B).

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.

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.

Attention Deficit Hyperactivity Disorder (ADHD) is one of the childhood disorders in India that has been the attention of both the medical and educational fields. A child with ADHD faces many challenges in reading. The present study focuses on the sub skills relating to Concepts of Print, components of decoding and reading comprehension. Eighty five children with ADHD in the age group of six to eight years studying in mainstream schools in Tamilnadu, India were the participants of the study.

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.

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 .

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.
