Thunderstorm outflows preceding epidemics of asthma during spring and summer.
BACKGROUND A study was undertaken to assess the importance of thunderstorms as a cause of epidemics of asthma exacerbations and to investigate the underlying mechanism. METHODS A case control study was performed in six towns in south eastern Australia. Epidemic case days (n = 48) and a random sample of control days (n = 191) were identified by reference to the difference between the observed ...
متن کاملCharacteristics of Lightning Discharges and Electric Structure of Thunderstorm
Progresses in the research on physical processes of lightning discharge and electric structure of thunderstorm in the last decade in China have been reviewed. By using the self-developed lightning detecting and locating techniques with high temporal and spatial resolution, the characteristics and parameters of lightning discharge in some representative areas in China have been obtained. Observa...
متن کاملThe effects of vertical outflows on disk dynamos
We consider the effect of vertical outflows on the mean-field dynamo in a thin disk. These outflows could be due to winds or magnetic buoyancy. We analyse both two-dimensional finite-difference numerical solutions of the axisymmetric dynamo equations and a free-decay mode expansion using the thin-disk approximation. Contrary to expectations, a vertical velocity can enhance dynamo action, provid...
متن کاملDerivation of Thunderstorm Ice Hydrometeor Characteristics from Lightning Measurements
Previous calculations (Blyth et al., 2001) predicting that the lightning frequency f is proportional to the product of the downflux p of solid precipitation (graupel) and the mass upflux I of ice crystals, have been subjected to preliminary examination by analyzing data from the STERAO experiment. The analysis has yielded provisional support for this flux hypothesis. The physical reasons for su...

گوشت قرمز یکی از مهم ترین فرآورده های دامی در تأمین پروتئین و انرژی می باشد که در حمل ویتامین های محلول در چربی نیز حائز اهمیت می باشد. انسان مانند سایر مهره داران اسید های چرب ضروری (لینولئیک و آلفا لینولنیک) مورد نیاز خود از طریق غذا تأمین می نماید. اسید های چرب ضروی پیش ساز اسید های چرب غیر اشباع با چند پیوند دوگانه هستند. اسید لینولنیک پیش ساز اسیدهای چرب امگا 3 و اسید لینولئیک نیز پیش ساز ...
