The cholesteatoma of the middle ear is a chronic otitis qualified as dangerous because of the risk of evolution of potentially serious complications. Labyrinthine fistula represents an erosive loss of the endochondral bone overlying the labyrinth. Labyrinthine fistula occurrence is one of the most common complications in chronic otitis media with cholesteatoma(2-3). Very commonly , the fistula is seen in the lateral semicircular canal(6-7). But very rarely cases of lysis for the three semicircular canals. We report the case of 30-year-old man admitted to the emergency for right fetid purulent otorrhea and rotary type vertigo for 15 days, who presented a chronic right sided otorrhea 8 years ago and homolateral hypoacousis. Computed tomography shows lysis of the 3 semicircular canals. The treatment is essentially surgical with open technique. Regression of vertigo and dry ear is the benefits.

Mathematics has double characters including science and technology. What sort of technology the mathematics is? The direct research object of mathematics is mode, and the mode is the carrier of information, and the evolvement of mode is the process of information processing and information conversion. Therefore, mathematics is the technology of information processing and information conversion.

Increasing need for energy and limited fossil resources, increasing environmental pollution resulting from the burning of these resources, the effects of global warming and the greenhouse effects, acid rain and the need to balance the propagation of CO2, all call for the necessity of saving fossil resources and increased attention to the use of renewable energy sources. Wind energy is one of the main types of renewable energies that have always attracted the human mind so that man is always thinking of using this energy in the industry. The human had been used wind to move boats and sailing ships and windmills. In the current situation with regard to the above mentioned terms and economic justification of wind energy compared to other energy sources, wind energy seems to be vital and essential. This article firstly provides an introduction to the field installation locations of wind turbines in the power system and then various methods for predicting wind speed and power of wind farms are expressed. After that Modeling of wind powerhouses are explained. Finally, wind powerhouse modeling methods are fully described and the equations of each model are given.

Numerous studies on adolescents have explored factors associated with sexual risk-taking behaviors among youth. However, few studies have examined the link between social exclusion of youth in social and sexual matters and sexual risk-taking behaviors associated with HIV/AIDS infection. This study was carried out using cross sectional design among 365 students randomly selected in secondary school in Bondo District, Kenya in order to determine the link between social exclusion and sexual risk-taking behavior associated with HIV/AIDS infection. The study also examined the moderating effect of age, gender and orphanhood on the relationship between social exclusion and sexual risk-taking behaviors. The findings of the study revealed positive correlation between social exclusion and sexual risk-taking behavior associated with HIV/AIDS infection. The study found out that age, gender and orphanhood moderates the relationship between social exclusion and sexual risk-taking behavior. Conclusion drawn from the study was that an increase in exclusion of youth on basis of age, gender and orphanhood could hamper efforts to slow down the spread of HIV infection in successive generations. Current best practice emphasizes the need for multilevel inclusion of youth in the family, schools, church and societal decision making processes in social and sexual matters that affect them.

The study was conducted on the morphological aspects such as shell shape and shell dimensions of freshwater snails Bellamya dissimilis and Lymnaea acuminata. The shell of B. dissimilis is globular in shape with broad ovate mouth and 4-5 whirls that are dextrally rotated. Shell length and shell width ranges from 2.3-3.9cm and 3.2-5.9cm respectively. Snail B. dissimilis gives birth to a large number (120-130) of fully developed young ones measures up to 0.2-0.5cm in length. The shell of L. acuminata is tapering conical with 3-5 whorls that end in dextral opening of shell. Shell length and shell width ranges from 1.2-2.7cm and 1.9-3.5cm respectively. The snail is hermaphrodite and breeds almost throughout the year, this snail contains the egg clutches and each egg clutch contains 170-180 eggs.

Elephantiasis results of chronic lymphedema due to a variety of obstructive diseases of the lymphatic system. It’s a rare disease outside areas where filariasis is endemic. Peno-scrotal Elephantiasis is characterized by gross enlargement of the genitalia and legs. Observation: We return a case of a 45-year-old patient referred for a giant scrotum for 10 years. The disease become disabling in that it makes sexual relations difficult, affects urination and also limited the patient mobility. He underwent a complete surgical resection of pathological tissue and peno-scrotal reconstruction, with good functional and aesthetic results. Pathology of the specimen was suggestive of either a non-specific fibrosis. We update through a review of the literature aspects of the diagnostic and therapeutic care of the peno-scrotal elephantiasis.

Turbo codes are one of the most powerful error correcting codes. In this paper focus is made on Bit Error Rate (BER) performance analysis of MAP, Log MAP and Max Log MAP turbo decoding algorithms in wireless AWGN channels. The research is investigated in several aspects to evaluate the performance of turbo codes in AWGN channel with different Signal to Noise Ratio (SNR), different generator polynomials and for different constraint lengths. The simulation results give some demonstrations that are valuable for the applications of turbo codes in AWGN channel with different SNRs.

Osteoporosis is one of the unpredictable disease, in which the micro architecture of bones becomes weak due to the low bone mineral density. Today this disease is very common amongst old people aged more than 50 years. This common public health problem has no symptoms and only technique available to diagnose is dual-energy x-ray absorptiometry (DEXA) scan. Generally bone mineral density (BMD) can be measured using DEXA, which is compared against the standard BMD values for diagnoses. The availability of DEXA machine in a country like India is a serious issue, because of its high cost and the high percentage of population living in rural areas with limited health care facilities. Here, our aim is to detect this disease on the basis of patient’s medical history without the necessity of DEXA scans report; so that it becomes feasible for the Indian population. For this proposed work will try to implement various Soft computing techniques which are available now- a- days.

Ketoprofen, an anti-inflammatory drug, exhibits poor water solubility and flow properties, poor dissolution and poor wetting. Consequently, the aim of this study was to improve the dissolution of ketoprofen. Microparticles containing ketoprofen were produced by spray drying and spray chilling technology to enhance dissolution rate. The prepared formulations were evaluated for in vitro dissolution and solubility. The produced drug particles were characterized by scanning electron microscopy (SEM), differential scanning calorimeter (DSC), x-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FT-IR). Dissolution profile of the spray dried micropartical was compared with chilled spray micropartical, pure sample and recrystallized sample. Spray dried micropartical exhibited decreased crystallinity, but for spray chilled particles there was evidence of polymorphic changes in the drug and improved micromeritic properties. The dissolution of the Spray dried micropartical was improved compared with spray chilling micropartical, recrystallized and pure sample. Consequently, it is believed that spray drying of Ketoprofen is a useful tool to improve wettability, solubility and hence the dissolution behavior of poorly water soluble drugs, in contrast to spray chilling technique.
