Improved DC utilization using advanced modulation techniques with Z source Inverter

Generally, an inverter is required to convert DC power generated by PV cell into AC power. A multilevel inverter (MLI) can synthesizes a staircase waveform. In this paper, a comparative study is made on performance of 5-level Z Source H Bridge inverter by considering advanced pulse width Modulation (PWM) strategies. PWM strategies of proposed ZSI’s is quite similar to the traditional carried-based PWM control method, the only difference is that to turn null states into shoot through states and keep the active switching states unchanged, so that the reliability of the inverter is greatly improved because miss-gating can no longer destroy the circuit. Keywords: Z source Inverter; PWM Schemes; Shoot Through; Photo voltai

It must be admitted that even today the extent nature of etiology, pathogenesis and diagnosis are all-debatable. Therefore, the present study was aimed at elucidating the age and mode of Benign Prostatic Hyperplasia among the patients in and around Hubli, Karnataka.Methods: The study was conducted after the institutional ethical committee approval and written informed consent from all the patients. 21 cases of BPH were included in the present study. The signs and symptoms of mode of presentation were recorded. The urine was examined for the presence of albumin, pus cells, epithelial cells and RBCs.  Results: The maximum incidence of the disease was in the age group of 60-69 years. Majority of the patients had difficulty in micturition followed by increased frequency of micturition both during day and night Patient with retention usually had distension of bladder. These patients complained of dull aching pain in the suprapubic area and in the groin region. Burning micturition (14.28%), dribbling of urine (4.76%), urgency (4.76%), and haematuria (4.76%) were present. Routine urine examination showed albumin (28.56%), pus cells (23.80%), epithelial cells (19.04%) and haematuria (4.76%).  Conclusion: Incidence of BPH at Hubli region of Karnataka is 0.3001% of total hospital admission. The maximum age incidence of BPH is in the age group of 60-69 years. Majority of the patients had difficulty in micturition increased frequency of micturition both during day and night a large number of cases show association with presence of urinary tract infection.

Comparative Study on Structural Parameter of R.C.C and Composite Building

Steel-concrete composite construction has gained wide acceptance world wide as an alternative to pure steel and pure concrete construction. However, this approach is a relatively new concept for the construction industry. Steel-concrete composite elements are used extensively in modern buildings. Extensive research on composite column, composite beam and deck slab in which structural steel section are encased in concrete have been carried out. However, for medium to high-rise buildings R.C.C structure is no longer economic because of increased dead load, less stiffness, span restriction and hazardous formwork. The results of this work show that the Composite structures are the best solution for high rise structure as compared to R.C.C structure.

A comparative study of the learning styles among 1st, 2nd and final year MBBS students

Background: Learning style is the way students begin to focus, internalize and remember new and difficult information. Identifying the learning styles of medical students will enable the faculty to use appropriate T/L method to increase the grasping ability of their subject/ learning. Purpose of the study was to assess and compare the learning styles of 1st, 2nd and final MBBS students by using VARK questionnaire.Methods: This was an observational, cross-sectional study based on the questionnaire, conducted by the department of Pharmacology at Basaveshwara Medical College and Hospital, Chitradurga. The VARK learning styles assessment questionnaire was administered to 1st (96 students), 2nd (60 students) and Final year (49 students). The students were categorized as auditory, kinaesthetic, visual learner or read/write depending on the predominant option they chose. Independent sample 't' test was used to compare the mean scores between the two groups using the software SPSS v22.Results: 40% of students had unimodal and 60% had multimodal learning style. Final year MBBS students had higher percentage of multimodal learning style (73%). The most preferred style of learning among all the medical students was kinesthetic (6.6), followed by aural (5.5), visual (4.0) and read/write (3.5). There was significant difference between the learning styles of 1st and Final year MBBS students in Visual (p=0.01) and Read /Write (p= 0.008).Conclusions: Knowing that students have different learning styles and kinesthetic being the most preferred mode of learning will help medical faculty to develop teaching/learning strategies for better outcomes

Prevalence and treatment patterns of dysmenorrhea among female medical students: a questionnaire based study at KIMS, Koppal

Background: Dysmenorrhea is a common gynaecological condition which causes physical pain, affects mental well-being and quality of life. The aim of the present study was to evaluate the prevalence, severity and the treatment patterns of primary dysmenorrhea among female medical students.Methods: The present study was a prospective, questionnaire based study conducted during March-April 2020 at KIMS, Koppal. The willing participants were given a time period of 30 minutes to fill the questionnaire.Results: Among the total of 211 female medical students, 180 students were suffering from dysmenorrhea. Almost 78.3% of those suffering from dysmenorrhea belonged to the age group of 19-21 years. Most of the students suffering from dysmenorrhea achieved menarche at the age of 13-14 years.  A majority (48.8%)  of the dysmenorrhic females had dysmenorrhea of mild degree. 73.8% of dysmenorrhic females did not seek any medical advice for the management of the symptoms of dysmenorrhea. 76 (42.2%) of the dysmenorrhic participant females missed their classes due to the symptoms of dysmenorrhea. The most favoured drug for the management of the symptoms of dysmenorrhea was the combination of mefenamic acid and dicyclomine (56.8%). 56.6% of the subjects utilized pharmacological measures, while the rest 43.3% utilized non-pharmacological measures for the relief from the symptoms of dysmenorrhea.Conclusions: The present study recognized that dysmenorrhea is a common menstrual disorder among young females. There should be an effort at mass education of the young females regarding the management of dysmenorrhea

SHORT COMMUNICATION: Status of Physical Fitness Index (PFI %) and Anthropometric Parameters in Residential School Children Compared to Nonresidential School Children

Background: Physical fitness is the prime criterion for survival, to achieve any goal and to lead a healthy life. Effect of exercise to have a good physical fitness is well known since ancient Vedas. Physical fitness can be recorded by cardiopulmonary efficiency test like Physical Fitness Index (PFI %) which is a powerful indicator of cardiopulmonary efficiency. Regular exercise increases PFI by increasing oxygen consumption. Residential school children are exposed to regular exercise and nutritious food under the guidance. Aims and Objectives: Our study is aimed to compare the physical fitness index status and anthropometric parameters in Residential Sainik (n=100) school children compared to Non-Residential (n=100) school children (aged between 12-16 years) of Bijapur. Material and Methods: PFI was measured by Harvard Step Test [1]. TheAnthropometrical parameters like Height (cms), Weight (Kg), Body Surface Area (BSA) in sq.mts), Body Mass Index (BMI in Kg/m2), Mid Arm Circumference (cms), Chest Circumference (cms) and Abdominal Circumference (cms) were recorded. Results: Mean score of PFI(%), Height(cms), Weight(Kg), BSA(sq.mts), BMI(Kg/m2), Mid Arm Circumference(cms), Chest Circumference (cms) and Abdominal Circumference (cms) were significantly higher (p=0.000) in Residential school children compared to Non Residential school children.
