Three ceramic compounds, LuFeO3, LuFe0.95Ir0.05O3, and LuFe0.90Ir0.10O3, were fabricated via using solid-state reaction technique. Scanning electron microscopy (SEM) analyses have shown the porous nature of samples. The loss-tan(δ) Ir substituted compounds are less than undoped sample at frequencies > 105 Hz. impedance study has revealed samples higher values. Z″ M″ vs frequency plots un...

The article investigates the processes of swelling liquid-glass compositions and production heat-insulating materials based on them under convective microwave heating. In work, it was established that nature curves conditions radiation heating are significantly different. Thus, during convection heating, there is an induction period, but then speed increases sharply process gradually slows down...

The study is an investigation into the effects of CDA and Ca (OH)2 on geotechnical properties expansive (Sample A) loose soil B). experiments were designed to adding in various percentages by weight (5%, 15% 15%) dry with 5% constant (OH)2, which produces pozzolanic reactions samples. Sample A was collected at Moniya, Ibadan, B from polytechnic, Ibadan and, cow dung obtained a farm settlement I...

Problem statement. A feature of the modern technical systems’ design is that deterministic approaches dominate, while consideration uncertainty can provide a more adequate representation research object in appropriate calculation scheme, mathematical model. The uncertainties becomes especially relevant modeling complex systems, where be quite abundant and themselves different nature, namely sto...

Araştırmada dört yıl inkübasyona bırakılmış biyokömürlerin buğdayın bazı verim ve öğelerine etkisini incelemek amaçlanmıştır. Bu amaçla 2017 yılında, saat boyunca 300, 500 700 0C derecelerde piroliz edilmiş biyokömürlerden parseller dekara 3 ton olacak şekilde uygulama yapılmıştır. 2020-2021 yetiştirme döneminde ise bitki denemesi kurulmuştur. Deneme sonuçlarına bakıldığında, biyokömür uygulama...

Background: The aim of the present study was to develop a three-dimensional (3D) collagen gel culture system for the in vitro growth and survival of buffalo preantral follicles with or without growth factors. Materials and Methods: Buffalo ovaries were collected from a local abattoir and preantral follicles were isolated through microdissection. Isolated preantral follicles were put either in c...
