Ocean colour sensors are equipped with atmospheric correction bands operating in the near infrared region of spectrum. At these wavelengths, ocean surface, because high absorption by water, acts as a dark background and sensor detected radiance is due to solar radiation backscattered air molecules aerosols called Rayleigh aerosol path radiances respectively. From bands, after accounting for rad...

This work presents multi-scale approaches to investigate 3D printed structured Mn–Na–W/SiO2 catalysts used for the oxidative coupling of methane (OCM) reaction. The performance has been compared their conventional analogues, packed beds pellets and powder. physicochemical properties were investigated using scanning electron microscopy, nitrogen adsorption X-ray diffraction (XRD). Performance du...

The oxidative coupling of methane (OCM) to C2 hydrocarbons (C2H4 and C2H6) has aroused worldwide interest over the past decade due rise vast new shale gas resources. However, obtaining higher selectivity can be very challenging in a typical OCM process presence easily oxidized products such as C2H4 C2H6. Regarding this, different types catalysts have been studied achieve desirable yields. In th...

PURPOSE Choroidal malignant melanomas (CMMs) are the most common primary intraocular tumors in adult humans. Although radiotherapy is commonly used to treat the melanomas, the therapeutic effects are unpredictable. The purpose of this study was to search for a gene(s) that can predict the success of radiotherapy for CMMs. METHODS The cell lines 92-1, OCM-1, and OMM-1 were established from pat...

ch4, c2h6 and c2h4 are the most important outlet gaseous of oxidative couple methane (ocm) reaction and this process is a new technology for conversion of natural gas to ethane and ethylene products. in this study, adsorption of ocm outlet hydrocarbons over 10x zeolite has been examined at equilibrium conditions. temperature and pressure are the most effective operational parameters in the batc...

Human uveal melanoma is the most common primary intraocular tumor, and brachytherapy is one of the most common and effective treatment strategies. In order to find a safer and more effective way to increase the radio sensitivity of the tumor, we tried to use the dendrimer nanoparticle performing coexpression gene radiotherapy. In this study, we constructed recombinant DNA plasmids (early growth...

Despite an improved understanding of cancer molecular biology, immune landscapes, and advancements in cytotoxic, biologic, and immunologic anti-cancer therapeutics, cancer remains a leading cause of death worldwide. More than 8.2 million deaths were attributed to cancer in 2012, and it is anticipated that cancer incidence will continue to rise, with 19.3 million cases expected by 2025. The deve...

رابطه‌­ی شدت ترمولومینسانس براساس مدل سینتیک مرتبه‌­ی اول بدون در نظرگرفتن اثر فروکشی دمایی مورد استفاده قرار می‌­گیرد. این حالی است که به عنوان یک واقعیت فیزیکی باید روابط بیان‌­کننده‌­ی توجه گیرد. کار با نظر گرفتن برای اول، تابع جداسازی منحنی تابش جدیدی برحسب و دمای قله دست آمد. نحوی جدید حذف مشخصه‌­های دمایی، همان قبلی خود تبدیل می‌­شود. دزیمتر (400TLD-) :Mn2CaF بررسی گرفت. این‌­که ­شدت طبق ...
