Detection and Discrimination of Islanding and Faults in distribution system with Distributed Generation by using Wavelet based Alienation approach

This paper presents a wavelet transform based alienation technique for the protection of a radial 5 bus  distribution system integrated with four wind type doubly fed Induction generators (DFIG).This technique is used to detect islanding condition and faults, classification of faults and their discrimination. Islanding is simulated at point of common coupling (PCC) and faults are simulated at each DG bus of the network. Daubechies wavelet transform has been used to decompose the current signals to get approximate coefficients. The Alienation coefficients of these approximate decompositions are termed as islanding and fault indexes. These indexes have been compared with predetermined threshold to detect islanding and faults. The same threshold value is utilized to discriminate transients associated with islanding and fault. Alienation coefficients at each bus over a half cycle window clearly detect both islanding and fault. Testing of the proposed algorithm has been carried out for various angles of incidence. Hence, the proposed algorithm is more effective and successful for finding the islanding condition as well as faults in distribution system with distributed generation

Effectiveness of Conventional Physiotherapy, High Intensity Interval Training (HIIT) and Low Volume High Intensity Interval Training (Low Volume HIIT) on Blood Pressure (BP), & Waist To Height Ratio(WHTR) in Primary Hypertensive Individuals: An Experimental study

BACKGROUND: A sedentary lifestyle has been characterized as an independent risk factor for cardio vascular disease. studies have shown the inverse association between physical activity level and the incidence of cardiovascular diseases. Historically, cvd has thought to be a disease endemic to developed countries only; However new evidence indicates that developing countries are more strongly affected by CVD than their affluent counterparts. Hypertension is an important risk factor for cardio vascular disease (CVD) affecting about 1 billion people worldwide. Elevated BP levels have been shown to be a risk factor for stroke, congestive heart failure, myocardial infarction, peripheral vascular disease & end stage renal disease. Essential hypertension accounts for 95% of all cases of hypertension. Essential hypertension is the most common risk factor for cardiovascular morbidity and mortality, affecting approximately 1 billion individuals worldwide, and is associated with substantial health care expenditure. AIM OF THE STUDY: To find out the effectiveness of conventional physiotherapy, high intensity interval training (HIIT) Vs low volume high intensity interval training (low volume HIIT) on blood pressure and waist to height ratio (WHtR) in primary hypertensive individuals. OBJECTIVES: 1. To find out the effectiveness of conventional physiotherapy on systolic blood pressure in primary hypertensive population. 2. To find out the effectiveness of conventional physiotherapy on diastolic blood pressure in primary hypertensive population. 3. To find out the effectiveness of conventional physiotherapy on waist to height ratio in primary hypertensive population. 4. To find out the effectiveness of HIIT on systolic blood pressure in primary hypertensive population. 5. To find out the effectiveness of HIIT on diastolic blood pressure in primary hypertensive population. 6. To find out the effectiveness of HIIT on waist to height ratio in primary hypertensive population. 7. To find out the effectiveness of low -volume HIIT on systolic blood pressure in primary hypertensive individuals. 8. To find out the effectiveness of low -volume HIIT on diastolic blood pressure in primary hypertensive individuals. 9. To find out the effectiveness of low -volume HIIT on waist to height ratio in primary hypertensive individuals. 10. To compare the effectiveness of conventional physiotherapy, HIIT and low -volume HIIT on systolic, diastolic and waist to height ratio in primary hypertensive individuals. METHODOLOGY: STUDY DESIGN: Experimental study. STUDY SETTING: Sports performance assessment research and rehabilitation centre (sparrc). SAMPLE SIZE: 30 subjects. STUDY DURATION: 6 months. SAMPLING METHOD: simple randomized sampling. INCLUSION CRITERIA: • primary hypertensive subjects. • Both male and female subjects. • Hypertension with asymptomatic, >2 risk factors (low risk subject). • subjects with age ranging from18-50years. EXCLUSION CRITERIA: • Secondary hypertensive individuals. • unstable angina pectoris. • uncompensated heart failure. • Recent myocardial infarction<4 weeks. • Recent CABG or percutaneous coronary intervention,<12 months. • Heart disease that limits exercise (valvular, congenital, ischemic, hypertrophic cardiomyopathy). • Ventricular arrhythmias and heart block. • Severe copd, cvd, uncontrolled pvd. • Uncontrolled diabetes mellitus. • Hypertensive subjects with bp>180/120or stage 3. • Severe neuropathy. • Chronic orthopaedic conditions. Materials: • Exercise tread mill, • Omron digital bp apparatus, • Inch tape, • Wall mounted ht measuring device, • Maximum heart rate chart, • Calculator. DISCUSSION: The present study was designed to find out and compare the effectiveness of Aerobics, HIIT and LVHIIT in the reduction of blood pressure and WHtr in hypertensive individuals. Even though all the three interventions were effective in significance level on reducing BP, little reduction was observed in waist to height ratio in all the three groups.Moreover,low volume high intensity training group exhibited excellent improvement comparatively in BP & waist circumference reduction. CONCLUSION: In primary hypertensive patients, aerobic exercise as gentle walking in moderate heart rate, HIIT, low volume HIIT with shortened exercise interval all can be beneficial in reducing systolic and diastolic BP and waist to height ratio. since LVHIIT group had shown greater significance and only moderate reduction in waist level by all the treatments, this study concludes that low volume HIIT could be more effective in reducing cardio vascular risk parameters of BP and WHtR but only average result may be seen in waist to height ratio

A successful pregnancy outcome in a testicular cancer survivor: case report

Testicular cancer is the most common cancer in young men. We report a successful pregnancy that was achieved by intracytoplasmic sperm injection (ICSI) using cryopreserved semen from a man with testicular cancer. He was treated for left testicular mixed germ cell tumor with left radical orchiectomy followed by chemotherapy. Three years post chemotherapy, the couple had two successive failures of intrauterine insemination (IUI) with cryopreserved semen. The couple then underwent Assisted reproduction with ICSI. Ten oocytes were retrieved following stimulation of which six oocytes fertilized and progressed. She had transfer of two healthy embryos and the remaining four embryos cryopreserved. Singleton pregnancy was achieved and she delivered a healthy girl baby at 38 weeks of gestation. Assisted reproduction with ICSI is a boon to the male patients with cancer and offers them a chance of fathering their own biological offspring

Fibroblasts and Phagocytic Cells in Phenytoin-induced Connective Tissue Proliferation

Objective: To evaluate the relationship of phenytoin-induced&nbsp;gingival enlargement and inflammation to find out if there is&nbsp;any significant correlation between hyperplastic index andperiodontal parameters, the number of fibroblasts and&nbsp;phagocytic cells.&nbsp;Background: The introduction of phenytoin as an anti-epileptic&nbsp;drug in 1938 marked the beginning of a new era in the treatment&nbsp;of grandmal epileptic patients decreasing significantly not only&nbsp;the epileptic attacks but also improving the quality of life.&nbsp;However, there is concern in dentistry regarding gingival&nbsp;overgrowth as a side-effect. A histological study of this tissue&nbsp;can shed some light on the changes taking place.&nbsp;Materials and methods: Twenty-four epileptic patients on&nbsp;phenytoin therapy were divided into two groups as follows:&nbsp;• Group I or test group of individuals who had been suffering&nbsp;from gingival enlargement,&nbsp;• Group II or control patients taking phenytoin without any&nbsp;gingival enlargement.&nbsp;Plaque, gingival and hyperplastic indices of anterior teeth&nbsp;were determined in all the subjects. Biopsy specimens of allpatients were taken and subjected to histopathological&nbsp;examination to determine the number of fibroblasts,&nbsp;macrophages, lymphocytes, and the level of inflammation,&nbsp;capillary proliferation and collagenation.&nbsp;Results: There is a significant increase in number of fibroblasts,&nbsp;macrophages, lymphocytes,collagenation and capillary&nbsp;proliferation in the enlarged gingiva of test group as compared&nbsp;to the control group.&nbsp;Conclusion: The degree of inflammation increases with the&nbsp;degree of enlargement. There is an increase in angiogenesisand the number of phagocytic cells thus indicating that&nbsp;phenytoin exerts growth promoting effects on the connective&nbsp;tissues.&nbsp

Rapid isolation of high molecular weight DNA from single dry preserved adult beetle of Cryptolaemus montrouzieri for polymerase chain reaction (PCR) amplification

For studying genetic diversity in populations of predatory coccinellid, Cryptolaemus montrouzieri Mulsant (Coccinellidae: Coleoptera), our attempts to isolate high quality DNA from individual adult beetle using several previously reported protocols and even modifications were quite unsuccessful as the insect size was small and was preserved at -20°C as dry specimen. Here we describe a simple, rapid and efficient method of isolating high-quality intact genomic DNA with reduced protein contamination for polymerase chain reaction (PCR) amplification from a single, dry preserved specimen of adult Cryptolaemus. The procedure features macerating and mixing the single adult specimen of Cryptoalemus with cationic detergent cetyltrimethylammonium bromide (CTAB) in the homogenization buffer, two chloroform-isoamylalcohol extractions and an alcohol precipitation. RNA contamination was eliminated with RNAse treatment. The purity of DNA was high since the A260/A280 ratio ranged from 1.78 to 1.97. The isolated DNA was used as template for PCR, and the results were evaluated by comparing with different preserved samples.Key words: Rapid isolation, quality DNA, dry preserved specimens, Cryptolaemus montrouzieri

Effects of Anacetrapib in Patients with Atherosclerotic Vascular Disease

BACKGROUND: Patients with atherosclerotic vascular disease remain at high risk for cardiovascular events despite effective statin-based treatment of low-density lipoprotein (LDL) cholesterol levels. The inhibition of cholesteryl ester transfer protein (CETP) by anacetrapib reduces LDL cholesterol levels and increases high-density lipoprotein (HDL) cholesterol levels. However, trials of other CETP inhibitors have shown neutral or adverse effects on cardiovascular outcomes. METHODS: We conducted a randomized, double-blind, placebo-controlled trial involving 30,449 adults with atherosclerotic vascular disease who were receiving intensive atorvastatin therapy and who had a mean LDL cholesterol level of 61 mg per deciliter (1.58 mmol per liter), a mean non-HDL cholesterol level of 92 mg per deciliter (2.38 mmol per liter), and a mean HDL cholesterol level of 40 mg per deciliter (1.03 mmol per liter). The patients were assigned to receive either 100 mg of anacetrapib once daily (15,225 patients) or matching placebo (15,224 patients). The primary outcome was the first major coronary event, a composite of coronary death, myocardial infarction, or coronary revascularization. RESULTS: During the median follow-up period of 4.1 years, the primary outcome occurred in significantly fewer patients in the anacetrapib group than in the placebo group (1640 of 15,225 patients [10.8%] vs. 1803 of 15,224 patients [11.8%]; rate ratio, 0.91; 95% confidence interval, 0.85 to 0.97; P=0.004). The relative difference in risk was similar across multiple prespecified subgroups. At the trial midpoint, the mean level of HDL cholesterol was higher by 43 mg per deciliter (1.12 mmol per liter) in the anacetrapib group than in the placebo group (a relative difference of 104%), and the mean level of non-HDL cholesterol was lower by 17 mg per deciliter (0.44 mmol per liter), a relative difference of -18%. There were no significant between-group differences in the risk of death, cancer, or other serious adverse events. CONCLUSIONS: Among patients with atherosclerotic vascular disease who were receiving intensive statin therapy, the use of anacetrapib resulted in a lower incidence of major coronary events than the use of placebo.
