Investigation on farm mechanization status of Kanker district Chhattisgarh was carried out for sustainable crop production. District falls in Chhattisgarh plains and Bastar plateau of agro climatic zones of Chhattisgarh having average rainfall varies from 1400 mm to 1500 mm where 90 % rainfall during the June to October. The total net sown area of the district is 2.37 lakh ha with cropping intensity around 122 %. To known the status of farm mechanization, level of mechanization was found out by considering available farm power sources namely human, animal and mechanical. A stratified multistage sampling design was applied considering block as a first stage, village as a second stage and cultivators are the final stage of the sampling. From Kanker district of Chhattisgarh. The 30 villages were selected from each seven block of Kanker district using Probability Proportional to Size (of Village). Then from each village, 10 cultivators were selected using random sampling. Primary data were collected from 300 cultivators from 30 villages. After selection of variables, a standard questionnaire was prepared to collect primary data. Average value of power availability, farm power consumption and present mechanization level is significantly highest in high productive blocks namely Charama, Kanker, Koilibeda in comparison to other four low productive blocks i.e. Antagarh, Bhanupratappur, Durgkondal and Narharpur block, respectively. Draft animal power available in study area was 0.41 bullock-pair per ha. The command area available per unit of power source for the marginal, small, medium and large farmers was 0.70, 2.01, 3.50 and 11.33 ha/bullock pair with over all availability of 2.42 ha per bullock-pair. However, tractor and power tiller manage the overall command area of 40.43 ha per tractor and 165.38 ha per power tiller. The mechanization level of Kanker district was found 1.37 kW ha-1.

A survey research was carried out in 2020 in maize zone, Jhapa to identify and analyze the status of farm mechanization and its impact in the maize production. Kankai Municipality and Jhapa Rural municipality were purposively selected for the study as these areas were under the command area of prime minister agriculture modernization project, project implementation unit, maize zone Jhapa. Thereafter, a total of 70 samples were selected using random sampling method. Thirty-three samples were selected from Kankai Municipality and remaining thirty-seven were selected from remaining Jhapa rural municipality. Primary data were collected using semi-structured questionnaire, focal group discussion and key informant interview whereas secondary data were obtained through a review of relevant literature. Both descriptive and analytical statistics were used to analyze the data. It was found that the status of mechanization was still in the initial phase in the study area. Results showed that mechanization was limited to two cultural operations namely tillage and threshing of which only in case of tillage, farm machineries were adopted by more than ninety percent of the respondent farmers while in case of sowing more than ninety percent of respondent didn’t use any modern equipment. Insect and pest in maize field was major problem faced by the farmers. Therefore, productivity of maize in Kankai area was higher as compared to Jhapa area as adoption of mechanization was higher in Kankai area.

One measure of the maturity of a device technology is the ease and reliability of applying contact metallurgy. Compared to metal contact of silicon, the status of GaAs metallization is still at its primitive stage. With the advent of GaAs MESFET and integrated circuits, very stringent requirements were placed on their metal contacts. During the past few years, extensive researches have been conducted in the area of Au-Ge-Ni in order to lower contact resistances and improve uniformity. In this paper, we report the results of TEM study of interfacial reactions between Ni and GaAs as part of the attempt to understand the role of nickel in Au-Ge-Ni contact of GaAs.N-type, Si-doped, (001) oriented GaAs wafers, 15 mil in thickness, were grown by gradient-freeze method. Nickel thin films, 300Å in thickness, were e-gun deposited on GaAs wafers. The samples were then annealed in dry N2 in a 3-zone diffusion furnace at temperatures 200°C - 600°C for 5-180 minutes. Thin foils for TEM examinations were prepared by chemical polishing from the GaA.s side. TEM investigations were performed with JE0L- 100B and JE0L-200CX electron microscopes.

Temporal And Spatial

Measurement of the egg's electrical activity, the fertilization potential or the activation current (in voltage clamped eggs), provides a means of detecting the earliest perceivable response of the egg to the fertilizing sperm. By using the electrical physiological record as a “real time” indicator of the instant of electrical continuity between the gametes, eggs can be inseminated with sperm at lower, more physiological densities, thereby assuring that only one sperm interacts with the egg. Integrating techniques of intracellular electrophysiological recording, video-imaging, and electron microscopy, we are able to identify the fertilizing sperm precisely and correlate the status of gamete organelles with the first indication (fertilization potential/activation current) of the egg's response to the attached sperm. Hence, this integrated system provides improved temporal and spatial resolution of morphological changes at the site of gamete interaction, under a variety of experimental conditions. Using these integrated techniques, we have investigated when sperm-egg plasma membrane fusion occurs in sea urchins with respect to the onset of the egg's change in electrical activity.

Personality Description

This paper describes the status of multicultural assessment training, research, and practice in the United States. Racism, politicization of issues, and demands for equity in assessment of psychopathology and personality description have created a climate of controversy. Some sources of bias provide an introduction to major assessment issues including service delivery, moderator variables, modifications of standard tests, development of culture-specific tests, personality theory and cultural/racial identity description, cultural formulations for psychiatric diagnosis, and use of findings, particularly in therapeutic assessment. An assessment-intervention model summarizes this paper and suggests dimensions that compel practitioners to ask questions meriting research attention and providing avenues for developments of culturally competent practice.
