AERODYNAMIC EFFECTIVITY ON THE MOVING OF HELICAL WINDMILL AS A SOURCE OF ALTERNATIVE ENERGY
Hertanto,Jenifer Taniya Maria 국제과학영재학회 2015 APEC Youth Scientist Journal Vol.7 No.2
The need of electrical energy is still depend on the fossil energy. Based on the data, Indonesian fossil energy reserves are decreasing, example oil reserves are merely enough for the next 23 years. While gas reserves are assumed will last until 50 years into the future and then coal for the next 80 years. If Indonesia only depends on fossil energy sources for the next 23-80 years, Indonesia will face a lack of energy supply. Therefore to overcome the case above, there is should be an effort to produce a renewable energy.. In this research, we took the initiative to take advantage of the wind gusts from the passing motor vehicles using helical windmill to overcome the unstable wind speed as an alternative source for lighting on roads, especially highways. The purpose of this study is to improve the effectivity of aerodynamic to the moving helical windmill as a source of an alternative energy.And the advantage of this blade is it can rotate continuously because it can recieve the wind from all direction and although the wind energy is very small the blade can still rotate. This study begins with designing a helical windmill, then a generator which is able to convert wind power into electricity. The generator designed consists of eight coils (1000 windings per coil), a saving current using 6 volt of battery, 1 ampere of transformer and the maximum rotation obtained is 12 volts. From this research, it can be concluded that the rotation speed of 367 rpm will produce 6.1 volts voltage, rotation speed of 406 rpm will produce 6.8 volts voltage, and rotation speed of 451 will be obtained 7.3 volts voltage.

Onychomycosis Caused by Aspergillus in a Patient with Leprosy: A Case Report

Aspergillus spp., one of the most common nondermatophyte molds (NDMs) that cause onychomycosis, are saprophytic fungi that can act as zoonotic agents and cause various health issues, including onychomycosis, in humans. Predisposing factors for onychomycosis include nail trauma, immunosuppression, and occupation. Nails in patients with leprosy are prone to change and develop onychomycosis due to unrecognized trauma to the nail area. Here, we report the case of a 25-year-old woman with 2-month history of white patches in fingernails and toenails, which were also brittle and damaged. She was a veterinarian who had frequent, direct interaction with animals, particularly dogs and cats. She denied trauma prior to the manifestation of symptoms and was undergoing leprosy treatment, including corticosteroids for leprosy reactions. Examination with potassium hydroxide revealed hyphae, and the nail culture revealed growth of fungal colonies with the characteristics of A. flavus. She received four cycles of itraconazole at 400 mg/day. Two of the three afflicted nails showed complete cure, whereas one nail showed mycologic cure. A. flavus is frequently found in animals, including dogs and cats and might have been a source of Aspergillus transmission, suggesting the patient's occupation and immunosuppression as risk factors for onychomycosis. Onychomycosis due to Aspergillus, particularly A. flavus, responds well to itraconazole pulse monotherapy.
