The action research was conducted to determine the effect of case-based teaching-learning on students’ analytical thinking experimented with the final year Bachelor of Business Administration (BBA) students, Gedu College of Business Studies, Royal University of Bhutan. The study was conducted between July and December, the Autumn Semester of 2020. There were 38 students in total who studied HRM307 Industrial Relations as their fifth major module for Human Resource Management group. Based on the survey conducted towards the end of the completion of module where 33 students participated, their opinion that the ‘case-based teaching-learning have improved’ analytical thinking stands at the mean value of 3.4 (out of 5). This indicates that the case-based teaching-learning intervention effect their analytical skills. The comparative study on the scores of assignment was also conducted. Although the mean score of the first assignment and the second assignment does not show significant difference, the average score of the first assignment and the third assignment has a statistically significant difference. This was confirmed through the paired sample t-test. Thus, it can be concluded that when the case intervention was prolonged over a period of time, it positively impacted students’ enhancement of analytical thinking.

The work aims to carry out a survey on the production and consumption of sausage in Benin. Indded, the sausage constitutes a source of protein and the surveys were carried out in the various communes of Benin, on the basis of a reasonable sample of 120 consumers and food sellers in each department of Benin. These surveys relate to the production of chicken sausage which is done according to the different stages which are the pre-treatment of raw materials, bonig, trimming, chopping, cutting, embossing, draining, druing and sterilization. These result showed that the majority of consumers surveyed use Minu and Morifresh brand sausages to accompany meals rich in protein. The results also showed that the different types of sausages are used to accompany several culinary dishes in Benin

Diverticular disease of the small intestine is rare, much less common than diverticular disease of the colon. The most common symptom is non-specific abdominal pain and a feeling of bloating sensation. Major complications include diverticulitis, gastrointestinal bleeding and acute perforation. Radiological imaging now allows precise diagnosis, and new endoscopic and interventional radiological techniques have made it possible to limit the urgent surgical indication. Conservative treatment is suitable for most asymptomatic patients. Surgery is still necessary in case of perforation or diverticulitis. We describe the clinical case of an 80-years-old female patient with left flank pain, abdominal computed tomography scan revealed an ileal tumor but diagnostic laparoscopy revealed an uncomplicated small bowel diverticular disease.

This paper presents the solution to the problem of grid voltage instability during occurrence of fault, on a system connected with wind turbine - driven doubly-fed induction generator (DFIG) which supplies alternating current (AC) power to the utility grid. Here, two pulse width modulated voltage source converters are connected back to back between the rotor terminals and utility grid via common direct current (DC) link. The grid side converter controls the power flow between the DC bus and the AC side. It allows the system to be operated in sub-synchronous and super synchronous mode of operation. The rotor excitation is provided by the machine side converter. The model makes use of d-q rotor reference frame using dynamic vector approach for machine model. The controller was implemented by the orientation of the generator stator flux vector along a synchronous reference axis. In this way, constant voltage and frequency was obtained and the generator would supply the active and reactive power demanded for the voltage correction by the load, while the wind turbine will be responsible for achieving power balance in the system. The system is modelled and simulated in the Matlab Simulink environment in such a way that it can be suited for modelling of all types of induction generator configurations. The results of the simulations show that DFIG wind turbines improved the voltage stability of the system through its ability to control reactive power and decouple control of active and reactive power by independently controlling the rotor excitation current especially during fault.

This work on the Effects of Treated Palm oil mill effluents (POME) on soil microflora was carried out using standard microbiological and chemical methods. Activated carbon used for the treatment of POME were generated corn cob, coconut shell and a combination of the two materials. Palm oil mill effluents were obtained from Umulolo community in Okigwe Local Government Area of Imo State. Top soil (10-15cm) and sub soil (of 15-30cm) samples were obtained from Federal University of Technology, Owerri farms. The Activated carbon were used separately and in combined forms to treat POME samples and the resultant wastewater, used to water the top and sub soil samples for four (4) weeks. The microbial flora of the watered soil samples were assessed using pour plate method. The results obtained revealed that the high microbial load of the untreated POME (TVC: 3.28 x 10? cfu/ml) reduced after the treatment with the activated carbon from agrowastes (Coconut shell TVC: 5.7 x 10? cfu/ml, Corn cob TVC: 1.03 x 10? cfu/ml and Cocunut shell + Corn cob TVC: 2.04 x 10? cfu/ml). There was a general increase in the microbial load of the top and sub soil samples watered with the treated POME when compared with the top and sub soil watered with the raw POME. The bacterial isolates obtained in this study were; Kebsiella pneumoniae, Bacillus subtilis, Staphlococcus aureus, Corynebacterium glaucum, Bacillus cereus, Pseudomonas aeruginosa, Streptococcus faecalis and Escherichia coli. The fungal isolates obtained were Cladosporium herbarum, Aspergillus niger, Penicillum chrysogenum, Rhizopus stolonifera and Candida albicans. From the results obtained in this study, it can be inferred that POME treatment with activated carbon removed the colloidal properties (usually one of the characteristics of POME), reduced the Biochemical oxygen demand (BOD), the chemical oxygen demand (COD) thus conditioning the soil for more microbial growth.

Collection of 13 leaves from Capsicum annuum L. was taken for the observation of symptoms caused by Alternaria solani on date 15/12/2020. Size of leaves noted between 6.88 sq. cm. to 31.96 Sq.cm and Maximum number of spots was 18. The other symptoms shoot out, half lamina absent (in leaf), swelling of green tissue along with yellow spot with white mycelium, giving powdery mass in some leaves were common. Anatomical study was done on Date 25/12/2020 at 2-3 P.M in the laboratory, Department of Botany, M.M.A.M.CAMPUS, BIRATNAGAR

The objective of this work was to provide an iconographic and narrative review of the normal and pathological aspects of the hippocampus of the elderly subject in imaging. Know how to perform a routine 1.5 Tesla MRI hippocampal study. Recognize the main hippocampal anomalies during degenerative, infectious, vascular, inflammatory, tumor, toxic and metabolic Take home message: interest of MRI in the study of the tonsil-hippocampal regions. Know the basics of the Anatomy of the Hippocampus and the Limbic System. Recognize the main hippocampal anomalies, during degenerative, infectious, vascular, inflammatory, tumor, toxic and metabolic summary The hippocampus is a small brain structure, internal temporal, playing a primary role in the mechanisms of memory. Magnetic resonance imaging (MRI) is the imaging modality of choice for the analysis of this structure. At the elderly, dementias represent the majority of causes of hippocampal abnormalities, especially atrophic, but other specific pathologies constitute differential diagnoses to be known in this population.

The Bas-Uélé Province is entirely agricultural, the crops grown in the past were peanuts, cotton and coffee. Currently, the food crops grown cannot alone solve the problem of poverty from which the population suffers. It is therefore time to think about introducing cash crops, especially cocoa from the Bambesa Territory.This part of the study which consisted in evaluating the phenological behavior of the cultivars of Yangambi showed that the cocoa tree can be cultivated in the pedoclimatic conditions of Bambesa: All the three hybrids introduced in Bambesa behaved well and can be disseminated as for their behavior thus their capacity of adaptation.
