The so-called self consistency method uses the fact that the true radar co-polar reflectivity (Zh e) and the differential reflectivity (Zdr ) can be used to predict the specific differential propagation phase (Kdp) at each radar range gate. The application of this method at S-band is relatively straight-forward as has been demonstrated in the past (e.g. Goddard et al., 1994). At C-band, one nee...
today, every enterprise needs to have its own business model. a business model explains what exactly the costumers want, how they want it and how the company can satisfy them. this can actually leads to the industry's competitive advantages and help the enterprises to revive them. in the late decades the prevalence of e-commerce leads it to be known as a tool to organize the business and s...
We have obtained spectra in the K band of the peculiar B[e]-star MWC 349. A 1.85–2.50 μm spectrum, measured at medium resolution, contains besides the strong IR continuum the first overtone CO bands, the hydrogen recombination lines of the Pfund series, and a number of other neutral atomic lines and ionic lines of low ionization, all in emission. Portions of the CO band and superposed Pfund ser...
OBJECTIVES We sought to separate the effects of associated left bundle branch block (LBBB) and coronary artery disease (CAD) on peak cardiac output (CO) during dobutamine stress in patients with dilated cardiomyopathy (DCM). BACKGROUND The mechanisms limiting CO during stress in patients with DCM are unclear. Both LBBB and CAD may do so by prolonging the total isovolumic time (t-IVT). METHO...
Plant sulfite oxidase [SO; E.C.1.8.3.1] has been shown to be a key player in protecting plants against exogenous toxic sulfite. Recently we showed that SO activity is essential to cope with rising dark-induced endogenous sulfite levels in tomato plants (Lycopersicon esculentum/Solanum lycopersicum Mill. cv. Rheinlands Ruhm). Here we uncover the ramifications of SO impairment on carbon, nitrogen...
تهران یک ابر شهر و پایتخت ایران است، بامساحت 700 کیلومتر مربع که کوه ها از شمال و شرق آن را احاطه کرده اند. رشد جمعیت و شهرسازی و توسعه ی صنعتی این شهر را با مشکل آلودگی هوا مواجه کرده است. تهران دارای چهار فصل همراه با متوسط بارندگی سالانه ی 210 میلیمتر است. دمای میانگین سالانه 17 درجه سانتی گراد و دمای بیشینه ی 39 درجه در تابستان و کمینه ی 6- درجه در زمستان می باشد. براساس اطلاعاتی که شرکت ...
