Influence of The Distribution of Gas Molecules by Temperature on The Rate of Gas-Forming Reactions
Get PDFA method is proposed for calculating the temperature distribution of gas molecules depending on the gas temperature . The method consists of determining the mean free path of molecules that characterizes the gas temperature, at which the maximum number of molecules with temperature , and then the desired distribution. The results show that at a given gas temperature, the total mass of molecules contains a large number of molecules whose temperatures are much different from the total gas temperature. From this, it follows that the ceramic technology of synthesis in principle does not allow us to obtain highly pure substances
Analysis of Trace and Essential Elements, Phenolic and Flavonoid Compounds in Libyan Honey Samples Collected from Misurata Markets
Get PDFHoney is a popular natural food product with a very complex composition comprising both organic and inorganic constituents. The composition of particular honey is strongly influenced by both natural and anthropogenic factors, which vary based on its botanical and geographical origins. It is observed that although the honey which are produced in Libya are of a good quality, it does contain heavy metals. The contents of the metals found in Libyan honey samples were found to be between 465.1-792 mg/kg for Na, 1100.8-1781.6 mg/kg for K, 927.79-1186.6 mg/km for Ca, 0.0033- 0.0177 mg/kg for Cd, 0.0029- 0.0241mg/kg for Pb, 0.0012- 0.0042mg/kg for Cr, 0.004-0.032 mg/kg for Cu, 0.72-1.37 mg/kg for Ni and 3.677-7.430 mg/kg for Zn. These results indicated that the quality of the Libyan honey samples tested was very good and matched the world standard properties of honey. Also, the Libyan honey samples examined have a high level of phenolic (792- 99 mg/kg ) and flavonoid (1012-687mg/kg) compounds compared with other hone
The Role of Green Energy Systems and Sustainable Development
Get PDFPeople are relying upon oil for primary energy and this will continue for a few more decades. Other conventional sources may be more enduring, but are not without serious disadvantages. The renewable energy resources are particularly suited for the provision of rural power supplies and a major advantage is that equipment such as flat plate solar driers, wind machines, etc., can be constructed using local resources. Without the advantage results from the feasibility of local maintenance and the general encouragement such local manufacture gives to the buildup of small-scale rural based industry. This communication comprises a comprehensive review of energy sources, the environment and sustainable development. It includes the renewable energy technologies, energy efficiency systems, energy conservation scenarios, energy savings in greenhouses environment and other mitigation measures necessary to reduce climate change. This study gives some examples of small-scale energy converters, nevertheless it should be noted that small conventional, i.e., engines are currently the major source of power in rural areas and will continue to be so for a long time to come. There is a need for some further development to suit local conditions, to minimise spares holdings, to maximise the interchangeability of the engine parts, and of the engine applications. Emphasis should be placed on full local manufacture. It is concluded that renewable environmentally friendly energy must be encouraged, promoted, implemented and demonstrated by a full-scale plant (device) especially for use in remote rural areas
International Data Demonstrating the Inverse Height and Life Expectancy Between the Sexes: Height and life expectancy
No full textMany papers have provided reasons for why women live longer than men. These include XX vs. XY chromosomes, sex hormones, and better care of their health. These factors certainly can affect male and female health but none has been proven to explain the actual difference that exists in life expectancy between the sexes. Another controversial factor commonly ignored is the size difference between men and women, but past research has shown that differences in male and female height and associated life expectancy are related by similar but inverse percentages (such as 8% taller and 9% shorter life expectancy). This paper provides additional evidence that supports early findings that shorter height is a major factor in explaining why women live longer. To test the inverse relationship between height and life expectancy, a list of developed countries was used to compare height and life expectancy differences between men and women. The results showed men were 7.8% taller and had an 8.5% lower life expectancy. These results are similar to previous study findings in 1992, 2003, and 2009. They are also consistent with scores of studies showing shorter or smaller body size is related to greater longevity independent of sex
The Congruence Effect of Leadership and Governance at the Grassroots. A Nigerian Perspective.
Get PDFThe effective administration of any society depends largely on the capacity of the leader. Every society must as a matter of fact have a leader either elected or appointed to pilot its affairs. In Nigeria, the grassroots are important as significant percentage of population still reside in local areas. This level is regarded as the closest government to the people, which also understand their peculiar needs and problems. It is therefore expected that leadership at this level should provide good governance to improve living standard of the local people. However, leadership performance in the rural areas has fallen short of expectation, thereby making good governance a tall dream. Based on this, the paper examined the leadership crisis and the crisis of governance at the grassroots with focus on the congruence effect of the former on the latter. The paper relied on content analysis method for its data. It was noted in the paper that poor leadership at the grassroots was responsible for governance crisis. The paper concluded that availability of good and transformational leaders at the grassroots will assist in entrenching good governance at the local government level
Extending the Applicability of an Efficient Fifth Order Method Under Weak Conditions in Banach Space
Get PDFWe extend the applicability of an efficient fifth order method for solving Banach space valued equations. To achieve this we use weaker Lipschitz-type conditions in combination with our idea of the restricted convergence region. Numerical examples are used to compare our results favorably to the ones in earlier works
Wilf's Formula and a Generalization of the Choi-Lee-Srivastava Identities
Get PDFThe identities of Choi, Lee, and Srivastava imply a formula proposed by Wilf. We show that these identities are immediate consequences of the well-known product formulas for the sine function and the cosine function. Moreover, we prove a generalization
Construction of Codes By Hyper KU-Valued Functions
Get PDFCoding Theory is a mathematical domain with many applications in Information theory. Various type of codes and their connections with other mathematical objects have been intensively studied. One of these applications, namely connections between binary block codes and BCK-algebras, was recently studied in (Jun, Song, Flaut ).In this paper, we will focus to one of the recent applications of KU-algebras in the coding theory, namely the Construction of codes by hyper KU-valued functions. First, we shall introduce the notion of hyper KU -valued functions, on a set and investigate some of it’s related properties. Moreover the codes generated by a hyper K U- valued function are constructed and several Examples are given. Furthermore, Example with graphs of binary block code constructed from a hyper KU-algebra and hyper KU-algebra are constructed
A Riccati-Bernoulli Sub-ODE Method for the Resonant Nonlinear Schrödinger Equation with Both Spatio-Temporal Dispersions and Inter-Modal
Get PDFThis work uses the Riccati-Bernoulli sub-ODE method in constructing various new optical soliton solutionsto the resonant nonlinear Schrodinger equation with both Spatio-temporal dispersion and inter-modal dispersion. Actually, the proposed method is effective tool to solve many other nonlinear partial differential equations in mathematical physics. Moreover this method can give a new infinite sequence of solutions. These solutions are expressed by hyperbolic functions, trigonometric functions and rational functions. Finally, with the aid of Matlab release 15, some graphical simulations were designed to see the behavior of these solutions
Enhanced AODV Protocol for Hybrid Wireless Network
Get PDFPerformance of algorithms in hybrid wireless network routing environments depends on end to end communication delay. Due to the fact that the end to end communication delay includes delay needed for finding the routing path & delay needed for actual routing. This delay increases exponentially as number of nodes increases, and can only be controlled till a certain network size, after which it is not optimum to use the underlying routing protocol, and change it in order to reduce the route computational delay. Thus, in order to provide improvement in Quality of Service (QoS) of hybrid wireless networks we need to off load this complex computational task to a high power and dedicated entity, which will be solely responsible for high speed route calculations. In this paper, we propose a cloud based routing algorithm, which utilizes the compute layer of the cloud in order to optimize the end to end communication delay, reduce the energy consumption, improve the network throughput and reduce the end to end communication delay jitter of the wireless networks
