The modeling of BLDC motor and performance analysis under diverse operating speed settings has been presented in this paper. BLDC motors gaining more & more attention from different Industrial and domestic appliance manufacturers due to its compact size, high efficiency and robust structure. Voluminous research and developments in the domains of material science and power electronics led to substantial increase in applications of BLDC motor to electric drives. This paper deals with the modeling of BLDC motor drive system along with a comparative study of modified queens bee evolution based GA tuned & manually tuned control schemes using MATLAB /SIMULINK. In order to evaluate the performance of proposed drive, simulation is carried out at different Mechanical load & speed conditions. Test outcomes thus achieved show that the model performance is satisfactory.

Aims: This study examined administrators rating of school counsellor’s competencies in information, counselling and follow-up service delivery. Three purpose statements, three research questions guided the study, while one null hypothesis was tested at 0.05 alpha level.

Study Design: Descriptive survey research design was adopted for the study.

Methodology: The population for the study comprised of 2076 administrators (head-teacher and principals). The sample drawn for the study is 208. The instrument for data collection was a questionnaire structured on a 4-point scale. The instrument was validated by two experts with a Cronbach reliability coefficient of .641. Arithmetic mean and standard deviation was used to answer the research questions, while analysis of variance (ANOVA) was used to test the null hypothesis at 0.05 alpha level.

Results: The results from the study revealed that moderate level of competence of school counsellors in information service delivery; school counsellors are moderately competent in follow-up service delivery. The findings also revealed that administrators (head-teachers and principals) differ significantly in their mean ratings on school counsellor’s competencies in guidance and counselling (information, counselling and follow-up) service delivery.

Conclusions: Core areas in guidance and counselling should be included in all colleges and universities curricula, routine inspection and review on the progress reports of school counsellors should be conducted and in-service training and retraining programmes for school counsellors should organized.

Introduction: Mental disorders are changes in psychological, mental or cognitive functioning, in which there is impairment, or suffering that impairs life habits, family, social interaction, among others.

Objective: To trace the epidemiological profile of psychiatry patients of Gurupi polyclinic -TO. Materials and Methods: Descriptive cross-sectional study with a quantitative approach, performed from the analysis of 104 medical records of patients in the psychiatric specialty attended at Gurupi-TO polyclinic. Data were collected on gender, age, the city of origin, the profession, marital status and medical diagnosis. The data were analyzed from descriptive statistics, in absolute and relative values.

Results: It was observed that people aged 6 to 84 years were observed, most of them female (63.5%). In addition, it is noticed that polyclinic users are mostly single (70%), residents of Gurupi city (84%). Regarding the profession, a high percentage of medical records do not contain these responses (58%), of the others are mostly from home (15%). The most prevalent disorders are bipolar affective disorder (34.2%) and depression (27.9%).

Conclusion: It is possible to realize that psychiatric disorders are predominantly affecting female patients, aged between 30 and 49 years, single, as a profession of "home", with fixed residence in the city of Gurupi and diagnosed predominantly with mental pathologies related to bipolar affective disorder and depression.

The study was conducted to understand the energy involves in cassava stem cutting in order to optimize design of cutting elements in cassava stem cutting. The cutting energy is measured using pendulum type test rig and it works under the principle of law of conservation of energy. The tests were conducted at 3 levels of average moisture content [43.75, 56.50 and 64% (wb)] and stem diameter (25.22, 28.71 and 33.29 mm) with 3 replications. The results revealed that the cutting energy was increased with increase in moisture content and stem diameter. The cutting energy of cassava stem increased by 23.26% when the average moisture content was increased from 43.75 to 64% and reduced by 17.31% when the stem diameter was increased from 25.22 to 33.29 mm.

Objective: Nectar is a sweet sustenance substance which organization, shading, flavor, and kind of nectar depend primarily on the blossoms, land districts and atmosphere and bumble bee species. We analyzed physicochemical and sensorial qualities attributed to different honey bee species in western Maharashtra of India.

Methodology: Apis dorsata, Cerana indica, Apis florea nectar from various bumble bee species from Kolhapur and Mahabaleshwar locale and remaining sample from market were studied for physicochemical and sensorial evaluation.

Results and Discussion: Brix of Cerana indica and Apis florea nectar gives 82.82 and 82.43°B which is higher than Apis dorsata and Market sample Honey. Acidity of the Apis dorsata was 0.38% which is higher than other nectar tests which showed matured marginal and gives the harsh unsuitable taste. Cerana indica test from Kolhapur district contains more sugar content 63.55% which gives dim golden color and better sweet taste increment its general agreeableness. Apis florea nectar sample from Mahabaleshwar district likewise contains more sugar content 63.35% with light golden shading and sweet taste. The market nectar similarly contains somewhat less sugar 62.10% with golden shading and furthermore contains more slag content. Its characteristic for Cerena indica and Apis florea nectar acknowledged by shopper than market sample honey.

Conclusion: Here we were the reason that the natural nectar test is superior to anything the nectar found in the consumer shops.

The main objective of the study was to determine the farmers’ attitude towards production and utilization of biochar as ecofriendly practice. Data were collected through personal interview from 104 randomly selected farmers at Nawabgang Upazila (sub-district) of Dinajpur district in the northern Bangladesh. A pretested and structured interview schedule was used to collect data from the respondents during 15 March to 18 April, 2017. Simple and direct questions with different scales were used to obtain information. Descriptive statistics are used to explain the selected characteristics of the farmers. The co-efficient of correlation (r) test was computed in order to explore the relationships between ten selected characteristics of the farmers and their attitude towards biochar production and utilization as ecofriendly practice. The results indicated that more than three-fourths (76.92%) farmers had highly favorable attitude towards biochar production and utilization as eco-friendly practice, while 15.38% moderately favorable attitude and 7.7% had slightly favorable attitude. Correlation coefficient analysis indicated that among 10 characteristics of farmers such as farm size, annual household income, training received, credit received, organizational participation and extension media contact had significant relationships with their attitude toward biochar production and utilization. However, age, education, family size and cosmopoliteness had no significant relationships with their attitude towards production and utilization of biochar as ecofriendly practice. The top ranked problem faced by the farmers in implementing of biochar production and utilization was found on ‘lack of woody fuel’. It might be recommended that biochar preparation should be done by using other raw materials such as tree leaves or branches, jute sticks etc available in the locality. Further proper steps should be taken by the concerned authority to maximize extension contact through farm visit, demonstrations and mass media on biochar benefits for enhancing the use of biochar.
