Analysis of Laminated Plates Subjected to Thermal/Mechanical Loads

[Abstract] [Full-Text PDF] [html]

Abstract: Three-dimensional thermo-elastic analysis of laminated plates subjected to uniform mechanical and thermal loads. The analysis is carried out by the finite element method using ANSYS, the most known software in the domain for it, two types of modeling are proposed: the first is modeling using a type of shell element, Shell 99 and the second is an approach based on a of type solid element, Solid 46. Deflections and stress resultants are obtained for symmetric and anti-symmetric cross-ply laminates for simply-supported boundary conditions at different temperatures. The results obtained are compared with the results of the shear deformation theory.

Towards the Stemming of the Tide of Strikes in Tertiary Institutions in Nigeria: Stakeholders’ Roles and Responsibilities

[Abstract] [Full-Text PDF] [html]

Abstract: In Nigeria, tertiary education has over the years been enmeshed in crises, one of these being the incessant strikes by the staff of tertiary institutions, under the aegis of different trade unions. Without mincing words, strike is now a ritual that has to be performed in every tertiary institution in Nigeria. Many people are contending that it is the language which government understands. It is thus no longer strange to government, students, tertiary institutions’ administrators, and other stakeholders in education. A new attempt is usually termed to be business as usual. This paper examines the issue of strike, as it affects tertiary education in Nigeria. Special focus is on the causative factors in Nigeria, such as: inadequate funding of education and tertiary institutions, interference in tertiary institutions’ affairs, increase in fuel price, low wages/poor conditions of service, poverty, refusal to honour past agreement(s), introduction/implementation of obnoxious policies by Government. The paper also discussed the effects of the strike such as the delay in graduation of students, loss of jobs, lives, and confidence in tertiary education, proliferation of private tertiary institutions, particularly the universities loss of value of certificates and status of tertiary institutions, increase in crimes, delay in mobilisation of graduates of tertiary institutions for National Service, inactive economic activities, falling standard of education, conflicts among the unions and staff of tertiary institutions. To stem the tide in tertiary institutions and move tertiary education forward in this decade and beyond, an effective administration of tertiary institutions, adequate funding of education/tertiary education by government, orientation of staff of tertiary institutions, among other measures, are recommended.

Variant Anatomy of the Cystic Artery: Case Reports

[Abstract] [Full-Text PDF] [html]

Abstract : Calot’s triangle (hepato- biliary triangle) as an orientation structure, determines the most common location of the cystic artery. The cystic artery varies in origin, course and number and it is important to recognize it during operative procedure Cystic artery is usually a branch of right hepatic artery given in the Calot’s triangle. Variations in the origin of cystic artery have been reported but there is paucity of literature regarding these in Indian subjects. The development of biliary vasculature is quite complex and it accounts for many variations. Knowledge of cystic artery variability facilitates intraoperative identification of vessels in both classical and laparoscopic surgery of the bile ducts. This emphasizes the importance of a thorough knowledge of the cystic arterial variations that often occur and may be encountered during both laparoscopic and open cholecystectomy. Uncontrolled bleeding from the cystic artery and its branches is a serious problem that may increase the risk of intraoperative lesions to vital vascular and biliary structures during hepatobiliary surgery.

Fatal error of the relativity and the research for dark matter,dark energy -the physical “dark world”

[Abstract] [Full-Text PDF] [html]

Abstract 1.The hard facts we given in text prove that, relativity theory is the fallacy from mathematical errors and experimental perjuries. 2.Conclusion of the study show that one called “fundamental gravitino” (the theoretical mass-energy value given at mw = 3.636 x 10-45 kg) is the Material composition of dark matter in the universe and also it’s the material composition of all the elementary particles too. This is the root cause that the gravitation has universality. In-depth research, the results show that the fundamental gravitino” in all space is the material foundation of the electromagnetic interaction and propagation of light and other physical phenomena. Furthermore it shows that Stable elementary particles are the “droplets” under the strong gravitino pressure (strength calculated are consistent with the strong interaction) in the entire universe, similar to the droplets in the saturated gas. There are steady-state solutions in Mathematical models corresponding to the proton, the electron and the neutron.The theory for topics such as the dark matter, the dark energy, and the Higgs particle has the perfect explanation and reasonable conclusion… It seems, Chinese began to keep up with the world’s physical trend, started a new physics era of fundamental gravitinothe mass energy source of the universe.

Global Issues and Local Realities: “Nation” in Folk and Corporate Cultures

[Abstract] [Full-Text PDF] [html]

Abstract: The present phase of cultural confluence, across the globe, has claimed major shifts in the patterns of human behavior and its socio-political manifestation. Be it the representation through any cultural artifact in particular or the changing geo-political spectacles of the world in general a state of hybridity is clearly visible. As far as the factors shaping the public opinion, distribution of resources and cultural configuration is concerned ,there has never been such shuffling of people and shifting of boundaries, intertwining of histories and overlapping of cultures as observed in the last three decades. The causes are, for this, too many to be enumerated. These may stretch from the emergence of a uni-polar world, increasing trends in power equation and sinister forms of economic colonialism to the satellite networking of regional groups and super expanding world trade. Consequently all the cultures have intermixed, and none has remained single and pure. A panorama of hybridity, heterogeneity and unmonolithic vision is clearly visible. In the contemporary socio-political structure of India two streams of thoughts are flowing side by side – the stream of the corporate/ elite and that of the masses. On the one hand, the poverty line goes down approximately 1$ per day as income, on the other there are classes that spend and earn more than thousands of dollars per day. The perception of the corporate class and common folk on different issues of society vary. The present paper focuses on the concept of nation as visualized by the above mentioned two classes in Indian socio-political structure.

Use of Fiber Glass (FG) in concrete mix to resist fires in installations (A case study on the columns)

[Abstract] [Full-Text PDF] [html]

Abstract: High temperature and Fires has become one of the biggest threats to buildings. Concrete is a primary building material and its properties of concrete to high temperatures have gained a lot of attention. But there is a fundamental problem caused by high temperatures that is the separation of concrete masses from the concrete block “separation phenomenon “. Separation of concrete leads to a decrease in the cross section area of the concrete column and so reduction the resistances to axial loads; also reinforcement steel bars become exposed directly to high temperatures, with the growing of incidents from major fires in buildings. Several samples of reinforced concrete columns with Fiber Glass have been used. Tow mixes of concrete been prepared using different contents of Fiber Glass (0.5 kg/m³ and 1.0 kg/m³). Reinforced concrete columns dimensions are (150 mm x150 mm x500 mm). The samples are heated for 1, 3 and 6 hours at 200 C°, 400 C° and 700°C and tested for compressive strength. Also, the behavior of reinforcement steel bars at high temperatures is investigated. Reinforcement steel bars are embedded into the concrete samples with 2 cm and 2.5 cm concrete covers, after heating at 700°C for 6 hours. The reinforcement steel bars are then extracted and tested for yield stress and maximum elongation ratio. The analysis of results obtained from the experimental program showed that, the best amount of Fiber Glass to be used is 1.0 kg/m³, where the residual compressive strength is 25 % higher than of that when no Fiber Glass are used at 400 C for 6 hours

Pragmatism and Challenges of Education

[Abstract] [Full-Text PDF] [html]

Abstract: Since its beginning, the philosophical trend of pragmatism, literally “Philosophy of Action”, was fostered by optimism that makes “the impossible” to “possible”. Such was American pragmatism with highly dynamic features that were discussed by Charles Sanders Peirce, William James and John Dewey. The concept of the truth when it serves the individual as well as the society would serve as the starting point of the view of John Dewey, to overcome the subjective dualism, a feature of the traditional philosophy. It was exactly their views that influenced the shaping of the so-called “Philosophy of Action”. However, the study will focus on the views of these thinkers on pragmatism and its usefulness to society

On the Construction of special metrics involving Levenshtein and Hamming distances

[Abstract] [Full-Text PDF] [html]

Abstract: Metric spaces are one of the useful types of topological spaces in measurement of length, and distance between points in underlying sets. They are useful for much more abstract and irregular sets than intervals in R2 or R3 . The ability to measure and compare distances between elements is often crucial and metric spaces provide more structure than general topological spaces. We begin by giving a brief introduction and background to topological spaces in general. We then go ahead to discuss metric spaces with a quick overview on concepts like connectedness, compactness, continuity and completeness and define formally what a metric is and give the basic properties of metric spaces. We state without proof some theorems in topology which we invoke subsequently in the construction of some metric spaces. A large class of metric spaces exists and this work illustrates the construction of some of these metric including the Hamming distance, the Levenshtein distance, the Hausdorff metric and other applications of metric spaces.

On the Study of Dynamical Model of Moods pertaining to etching behavioural patterns

[Abstract] [Full-Text PDF] [html]

Abstract: Often times, we experience ups and downs in our spirit, sometimes we have no vivid explanation to what we really feel within. We normally classify these feeling as “bad mood”. At times the situation is the other way round, we feel elated, “positive” and confident to go about our normal roles. During these periods in our lives, we are normally inclined to doing certain things that interest us. The question we ask ourselves is; is there a way to explain this inevitable feeling and how to manage them? Are there negative or positive effects associated with these feelings? In this research, we delve deeper into things that cause these ups and downs in our emotional feelings and their effects on our lives being it positive or negative. Upon further investigations and research, we present a model of second order ordinary linear differential equation to measure and describe the various changes in mood with time. The rapid and periodic changes between extreme moods forms (mood swings) is further elaborated with a mathematical model. The trend in the changes of mood is demonstrated graphically with elaborative commentary.
