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...

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...

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...

the environmental scanning electron microscopy (esem) is a new development in the field of electron microscopy. in this study esem has been used to study the structure of veal semimembranosus muscle. four treatments, raw (control), conventional heating, domestic and industrial microwave heating, were observed using esem. the temperature used in conventional heating was 163 0c. frequency app...

Aluminium is one of the basic materials used in many sectors, especially automotive, defence and aviation. Generally, aluminium parts are manufactured by using injection molding methods such as etc. Injection presses that for die-casting material have a lot parameters, affect molded parts’ properties. In this study, effect parameters on mechanical properties was investigated. Firstly, test part...

Previous studies have demonstrated the presence of myocardial depression in clinical and experimental septic shock. This depression is associated with the presence of a circulating myocardial depressant substance with physical characteristics consistent with cytokines. The present study utilized an in vitro myocardial cell assay to examine the role of various human recombinant cytokines, includ...

Lomonosov University, Moscow 119899, Russia Hydroxamic acids as the precursors oftheir organogermanium and organotin derivatives have been themselves intensively studied fi’om the viewpoint of their potential biological activities [1-3...

Lemma 23. ∀ T ∈ N, x̄ = (x0, x1, . . . , xT ) ∈ R, ∃ hx̄,T ∈ H such that (x0, x1, . . . , xT , 0, 0, . . .) ∈ C∗ hx̄,T+1 . Proof. For arbitrary h, define c by c0 = x0+φ(h), c h t = xt+φ(hc h 0c h 1 · · · ct−1) for all 1 ≤ t ≤ T , and ct = φ(hc0c1 · · · ct−1) for t > T . φ is strictly increasing, so we may choose hx̄,T ∈ H sufficiently large so that (c hx̄,T 0 , c hx̄,T 1 , . . . c hx̄,T T ) is nonnega...
