Harmonic reduction with transformer connected 3-phase multilevel inverter

Ali Jumah Ahmed, Manikant Kumar and Dr. Pratibha Tiwari

This paper proposes a Harmonic Reduction with Transformer Connected 3-Phase Multilevel Inverter arrangement employing a series connected transformer to suppress 7th, 11th &13th order harmonics (generated by non-linear loads).In the proposed scheme sinusoidal PWM signal generation technique is used for three phase multilevel VSI in conjunction with series connected transformer .The proposed model eliminates the need of output filter inductor. With this control strategy harmonic components of output voltage and switching losses can be minimized considerably. A simulation result verifies the proposed concept and indicates that the transformer is capable of reducing the harmonics in the line.

Comparison of two methods of tetramethylammonium dosing in fruit maeruapseudopetalosa (gilg and benedict) of wolf

Mahamat Seid Ali, Nicolas Cyrille AYESSOU Mady CISSE and Mathieu GUEYE

The population of poor agricultural yields areas have potentially very nutritional substitution food at their disposal. Among these sources, Maeruapseudopetalosas fruit (syn.Courboniavirgata) whose iron and potassium content highlighted allow the compensation of various nutritional deficiency. However, the fruit presents a toxicity that can be inhibited by lixiviation. The dosage method of this toxin, the tetramethylammonium (TMAH), is old and has been used earlier. This current scientific work suggests a new volumetric dosagemethod of the TMAH in Maeruapseudopetalosa fruit. Ripe Mareuapseudopetalosa fruit have been collected in two distinct vegetable areas, located in Kieneba and Koussane in the region of Tambacounda in Senegal. The dosage carried out on this fruit is essentially based on the volatility of ammonia derived from TMAH. Indeed, in highly alkaline environment, ammonia is distilled, then being dosed volumetrically. The results derived from operating conditions (aqueous extraction with a ratio of 1g/ml shaken for two hours at 25̊ C) have allowed in getting an average quantity of 5.69 ± 0.3 g of TMAH in 100 grams of seeds.

Clinical study of siravedhana and agnikarma in gridhrasi (sciatica)

Dr. Pramod Chandra Dwivedi

Gridhrasi is such a disease, which carry little threat to life and interfere greatly with living also. The person who suffers from this disease is particularly handicapped, as he can’t walk, stand or sit properly and the painful limb continuously draws his attention. The management provided by modern medicine for this condition is either conservative like rest, immobilization, analgesic and anti-inflammatory drugs, physiotherapy, manipulation etc. or surgical. If the pain and neurological findings do not disappear on prolonged conservative treatment, finally they go on surgery, which is also not the ultimate solution as there is a common problem of recurrence or some patients lose their working capabilities. Acharya Charaka has described Basti, Siravyadha (Venepuncture) and Agnikarma in the management of Gridhrasi. In this present study, 30 patients were observed randomly during this classical method for treating Gridhrasi (Sciatica). These 30 patients were divided in two groups on the basis of treatment Procedures. In Group I Siravedhana (Blood Letting) was performed and in another group II, Agnikarma Procedure was done on patients as per classical established method adopted by Ayurveda Acharya.

The effectiveness of contextual value clarification technique (cvct) model to improve the internalization of pancasila values

Sutoyo, Asrowi, Muhammad Ahkyar and Sri Anitah

This research aimed: (1) to find out the implementation of Pancasila and Civic Education (PPKn) learning occurring currently; (2) to measure the success of CVCT model in PPKn learning; (3) to analyze the effectiveness of CVCT model in improving the internalization of Pancasila values. This research was taken place in Vocational Middle Schools throughout Solo Raya Indonesia, with teachers and students being the subject of research. The data was collected using test, observation, interview, documentation, and questionnaire techniques. Data validation was carried out using triangulation technique, including method and source triangulations. Meanwhile, data analysis was carried out using interactive, descriptive, critical and comparative techniques and t-test. From the result of research, it can be concluded that: (1) In Pancasila and Civic Education (PPKn) Learning in Vocational Middle School, the teachers had not used an innovative learning model in delivering the learning material. Learning process was still teacher-oriented and material delivery had not been balanced between cognitive, affective and psychomotor aspects, however it still emphasized more on cognitive aspect. (2) The use of CVCT model in Pancasila and Civic Education (PPKn learning) could improve the internalization of Pancasila values in Vocational Middle Schools throughout Solo Raya. The internalization of Pancasila valuesimproved because CVCT is an innovative learning model, the learning process was student-centered and emphasized on the balance between cognitive, affective and psychomotor aspects, so that it would be attractive and generated motivation for the students.

Myths and misconceptions during menstruation: A review article

Uzma Eram and Tamanna, Z.

Menstruation is a phenomena unique to girls. However,it has always been surrounded by taboos and myths. Different cultures view menstruation differently. A menstrual taboo is any social taboo concerned with menstruation. There are very few empirical studies which comprehensively describes the psychological, social and physiological aspects of menstruation. It is important to understand the different restrictions and views of menstruating women in different religions. In this paper, we will discuss menstrual related myths prevalent in the world and their impact on women’s life. Culturally in many parts of India, menstruation is still considered to be dirty and impure. Many girls and women are subject to restrictions in their daily lives simply because they are menstruating. But now-a days women have become sensitive and aware towards their health. A number of women today treat menstruation as a very normal body function. The study suggests the need for health and hygiene programs for girls. Mothers should build healthy relation with their daughters and should come out of their culture.

Hand grip in relation to cubitus valgus deformity in children with hemiparetic cerebral palsy

Radwa S. Abdul-Rahman, Al Shimaa Ramadan Azab and Khalid A. Alahmari

The purpose of this study was to determine the relationship between hand grip and cubitus valgus in hemiparetic cerebral palsied children. Subjects and procedures: 25hemiparetic cerebral palsied children (boys and girls) between7 and 9years of age were selected to participate in this study. Cubitus valgus was measured by a universal goniometer and a handheld dynamometer to test for hand grip strength. Results: By comparing both affected and unaffected sides, it was revealed that there was a significant correlation in both variables of hand grip and carrying angle; however using the Spearman’s rank correlation coefficient test, there was no significant correlation found between hand grip strength in an affected hand and the carrying angle in an affected upper arm. Conclusion: Hand grip muscle strength was reduced and directly affected by the carrying angle in both the affected and unaffected upper arms as a result of the valgus position was of positive correlation with hand grip, meaning that a hemiparetic hand grasps all objects with an exaggerated opening throughout the entire movement without an anticipatory grasp formation which later the hand grip will be directly affected by the degree of cubitus valgus angulation.

Management of excessive gingival display by esthetic crown lengthening procedure

Sheethalan, M.S.R. and Kaarthikeyan, G.

Harmony between the teeth, gums and the lips are required for creating a beautiful and pleasing smile profile. Discrepancies in any one of the factors results in excessive gingival display and short clinical crowns which are not esthetically acceptable, ultimately affects the confidence of the person. Gummy smile caused due to gum overgrowth over the teeth can be treated by esthetic crown lengthening procedures where excess gingiva is removed to expose the natural length of the teeth. This chapter reports about esthetic crown lengthening procedure in patient with excessive gingival display.

Test for structural change under heteroscedastic and dependent errors: the case of successive regressions

Jagabandhu Saha

The Chow test is not robust when the errors are heteroscedastic as well as dependent. The presence of heteroscedasticity and dependency will affect level of significance as well as power of the test, especially when the sizes of the samples are small. The present paper not only resolves the problem of simultaneous existence of heteroscedasticity and dependency in the error terms, but also extends the existing method of comparing two regression equations to many equations in order to make comparisons of the successive coefficients to be possible, thus enabling one to detect structural changes, if any. The procedure is then illustrated through detection of structural change, by comparing the decadal growth rates of population, using State level data of India.
