The thermal performance of a Domestic Solar Cooker (DSC) was evaluated in this study in accordance with the Society of Agricultural Engineers Standard (ASAE S58, 2003). The DSC is a parabolic solar cooker type with a focal point of 1 m, diameter of 2.14 m, absorber surface area of 0.07 m2, concentrator surface area of 3.84 m2, and concentration ratio of 54 which uses a glass mirror as its reflector. Results of the study show that stagnation temperature of 320°C was attained at a heating rate...

Temperature and rainfall are among the climatic variables required in determining the availability of water in an environment, especially for agricultural purposes and domestic consumption by man. However, there are concerns that these variables are being affected by global warming which thus necessitates the need to study their impact on the environment such as the identification of drought. The mean monthly temperature and rainfall data utilized in this work were obtained from the Nigerian Met...

Introduction: Obstetric Fistula (OF) is an abnormal communication between the bladder and the vagina or between the rectum and the vagina and or both. The objective was to describe the experience of OF by the victims. Methodology: The gynecology-obstetrics clinic of the CHU Sylvanus Olympio in Lomé served as the framework for this study. This was a descriptive cross-sectional study, which took place from February 28 to March 19, 2011. Results: A total of 76 women with OF were interviewed. Mother...

Alpha-amylase is a starch hydrolyzing enzyme which has many industrial applications. In this study, Bacillus subtilis QM3 has ability to produce α-amylase. Identification was done by iodine test, based on the clear zone around the sample in starch agar plates. Alpha-amylase activity was measured using 3,5-dinitrosalicylic acid (DNS). The result showed B. subtilis QM3 can produce α-amylase and activity of α-amylase was 50.58 IU/mL. The study on enzymatic properties was found: the optimum temperat...

Objective: To investigate the effects of cytokines IL-10 and IL-15 in osteoporosis, and to provide a basis for the prevention and treatment of osteoporosis. Methods: A total of 101 subjects who underwent bone density testing in Linyi People’s Hospital from January 2018-December 2019 were selected and divided into normal bone density group, osteopenia group and osteoporosis group according to their bone density. At the same time, the peripheral serum IL-10 and IL-15 levels of subjects were detect...

The aim of this paper is to examine the idea of Royal Dutch Shell’s acquisition of the BG Group and how it has created the world’s largest natural gas liquefied business. For more than ten years, it was the first mega-merge in the sector for $54.0 billion in 2016. The study will explain the critical analysis of the motivations behind each deal for acquiring BG Groups by Royal-Dutch multinational Shell PLC. The paper also analyzes various Financing methods, similarities and differences, and relat...

This paper redefines the Shape of numbers, makes it more natural and concise, and the domain of definition is extended to ring. The inconvenient PCHG() and PH() are removed. The concept of subsets is also removed. The new definition can be used to calculate ∑ n-0N-1Π i-1M (K i n×D i)
∑ ni,j-0j-N-1Π i-1...

Wh-question has aroused considerable attention of linguists around the world. English is a wh-movement language, while Chinese is commonly recognized as a wh-in-situ language. By the advent of the Minimalist Program outlined by Chomsky, the syntactic derivation in a phase-based approach has reduced the computational operation. The syntactic structures are built in a bottom-up and one-phase-at-a-time way. Merge and Agree are the most basic syntactic operations. The paper presents how Phase Theory...

In this paper 2D discrete time dynamical system is presented. The fixed points were found. The stability of fixed points is measured by characteristic roots, jury criteria, Lyapunov function. All show that the system is unstable, and analyzing the dynamic behavior of the system finds bifurcation diagrams at the bifurcation parameter. Newton’s Raphson numerical method was used the roots of the system with the minimum error. Then, chaoticity is measured by the phase space; maximum Lyapunov exponen...
