Experiments at Mbaga hills of Siaya County in Kenya were aimed to determine the most effective organic baiting technique for mass harvesting Macrotermes bellicosus. Around two separate mounds, 5 treatments replicated 3 times, using earthen pot and plastic containers with maize stocks, eucalyptus stems, lantana camara twigs, Napier grass rice husks, set up. Termite counts, 6.00 am pm, data on te...
We adopt the following convention: x1, x2, z are sets, A is a non empty set, and f , g, h are elements of CA. Let us consider A. The functor +CA yielding a binary operation on CA is defined by: (Def. 1) For all elements f , g of CA holds +CA(f, g) = (+C)◦(f, g). Let us consider A. The functor ·CA yielding a binary operation on CA is defined as follows: (Def. 2) For all elements f , g of CA hold...
در این پژوهش با استفاده از داده های اندازه گیری شده پارامترهای هیدرو فیزیکی دما، شوری و عمق در سال 2003 میلادی توسط پژوهشگاه علوم اقیانوس شناسی و جوی (سواحل بابلسر)، در ابتدا سرعت صوت در فصول مختلف سال طبق رابطه ی مدوین محاسبه گردید. سپس، نیمرخ های افقی و قائم دما، شوری و سرعت صوت با استفاده از نرم افزار matlab ترسیم شد. نتایج حاصل از تجزیه وتحلیل این نیمرخ ها نشان داد که در فصل تابستان و پاییز...
The melting layer (ML) is a significant phenomenon in weather radar observations. It consists of initially frozen hydrometeors falling into air below the 0C isotherm (freezing level) where they start melting. The radar echoes from melting hydrometeors differ from those from rain droplets as well as from frozen hydrometeors, and ML is observed as the radar bright band. The ML is a complex atmosp...
This paper presents a 10-bit pipeline ADC using double sampling technique to achieve a conversion rate of 40 MS/s at 2.5-V supply. The opamps are two-stage with folded-cascode as the first stage and feature techniques such as common-mode stabilized active load, crosscoupled cascode connection, and close-loop pole placement. MOS switches are driven by bootstrapping circuits that do not subject t...
Carboxymethylcellulases (CMCases) of Arachniotus citrinus were produced under solid state fermentation on different carbon sources including wheat bran, corn cob, alkali treated corn cob and mixture of wheat bran and alkali treated corn cob at 30C for 15 days. In this case, mixture of wheat bran and corn cob was observed to be the best carbon source as maximum specific activity (4.2 U mg protei...
شکست حرارتی هیدروکربن ها در حضور بخار آب یک روش متداول و کارامد برای تولید اتیلن و پروپیلن محسوب می شود. در این پایان نامه شکست حرارتی خوراک مجتمع الفین 12(در دست طراحی) بررسی شده است. خوراک الفین 12 مورد استفاده در این پایان نامه، حاوی 26/65% نرمال پارافین، 28/28% ایزوپارافین، 17/84% نفتن و 19/3% آروماتیک می باشد. برای انجام آزمایشات، از طراحی آزمایش ccd به دلیل دقت بالا و تعداد کم آزمایشات، ا...
Embolic events are frequent and life-threatening complications of infective endocarditis (IE), related to the migration cardiac vegetations. The risk embolism is very high in IE, with embolic occurring 20-50%of patients. brain spleen most common sites left-sided IE. Stroke a severe complication associated increased morbidity mortality rates. Case presentation: A 73-year-old male presented Emerg...
The paper presents the results of research into technological regime process liquid-glass composition porization under action microwave radiation to achieve effective removal all types water and obtain heat-insulating materials with high operational properties. It was established that a power 500 W in vacuum environment without rotation sample, despite achieved temperature value 110-115 oC, int...
Hafnium oxide (HfO2) high-k thin films have been deposited by radio frequency (rf) sputtering technique on p-type Si (100) substrate. The thickness, composition and phases of films in relation to annealing temperatures have been investigated by using cross sectional FE-SEM (Field Emission Scanning Electron Microscope) and grazing incidence x-ray diffraction (GI-XRD), respectively. GIXRD analysi...
