Well Placement Optimization Using a Basic Genetic Search Heuristics Algorithm and a Black Oil Simulator  [PDF]
Charles Y. Onuh, David Alaigba, Oluwatosin J. Rotimi, Bamidele T. Arowolo
Open Journal of Yangtze Oil and Gas (OJOGas) , 2017, DOI: 10.4236/ojogas.2017.24017
Abstract: In petroleum reservoir management, the essence of well placement is to develop and maintain reservoir pressure in order to achieve maximum production for economic benefits. Large production can be achieved with the placement of multiple wells but this approach is capital intensive and inefficient for the development of a reservoir. A preferable option is the optimal placement of production and injection wells so as to fully capitalize on the imbedded hydrocarbons at a relatively decreased capital investment. The aim of this study is to use developed algorithm and a black oil simulator to place wells in the zones for optimal recovery in the reservoir. Optimal production was determined out of eight scenarios created from well placement in a hypothetical reservoir (finch reservoir) using a black oil simulator, alongside an algorithm developed with java for determining the best possible locations for well placement, taking into consideration the reservoir permeability, fluid saturation, and pay zone thickness. The results of this study reveal that well placement using the engineering judgment coupled with the application of the algorithm using a black oil simulator results in better production compared to other scenarios which consider the combined effect of algorithm and black oil simulator alone.
How Do You Know What You Know: Epistemology in Software Engineering  [PDF]

Journal of Software Engineering and Applications (JSEA) , 2017, DOI: 10.4236/jsea.2017.102010
Abstract: Ubiquitous computing emphasizes the notion of automation in the daily human experience. With the ease, comes the responsibility of knowing, the knowledge of the intrinsic nature of the machine and the evolution of human-computer interaction (HCI). The quest for knowledge is engrained in the act of questioning itself. “How?” “What? “Why?” dominates the vocabulary of every scientist and models the endlessness of our natural inquisitiveness. For example, an interaction of software systems in the case of a user who withdraws money from the ATM and automatically gets a text message and an e-mail containing notification of the transaction, engenders questions about how it all works; in technical terms, the nature of the special science that enables wireless communications. Knowledge that derives from aphorisms or other self-evident truths is easier to acknowledge, for example, the knowledge of “multiplication” is justified by the truthfulness of “addition”—the Apriori. However, in Software Engineering (SE), the Apriori is more obscure. The investigation of the nature of knowledge in SE requires an expansion of the general idea of the Apriori in establishing knowledge.

Abstract: Agricultural productions in developing countries have largely been on subsistence basis. The farmers only produce for their families and quantity of food produced are grossly inadequate for the growing population. There is increase widespread in the level of poverty amongst the people, most especially those living in the rural areas. Small scale farming has become one of the ways to tackle the problem of lack and poverty amongst these people. The paper therefore, examines how Small Scale farming assists in alleviating poverty in both rural and urban cities; most especially through marketing of agricultural products to the people. Relevant data were sought from the 356 respondents selected for the study through the Key Informant Interviews (KII). The Student T test and Chi square statistical techniques were further employed to test the Hypotheses stated in the study. Result of the finding reveals the importance of Small Scale Farming and Agricultural Products Marketing in poverty alleviation, most especially among the rural dwellers. It also indicated lack of access to fund as the major problem facing Small Scale Farming and increase cost of transportation as the major problem facing marketing of agricultural products. The Paper recommends that Individuals and Government can combat some of these challenges facing Small Scale Farming by providing adequate basic social infrastructures; make available more funds to the farmers and create more employment opportunities amongst others. The paper concludes that Agriculture no doubt, is an important sector that needs to be given attention in any developing economy. Key words: Small scale farming; Marketing; Rural dwellers; Key interview guide; Agricultural products and poverty Résumé: Les productions agricoles dans les pays en voie de développement étaient principalement sur la base de subsistance. Les agriculteurs ne produisent que pour leurs familles et la quantité des aliments produits est nettement insuffisante pour la population croissante. Il y a une augmentation généralisée de la pauvreté parmi la population, plus particulièrement ceux vivant dans les zones rurales. L'agriculture à petite échelle est devenue l'une des fa ons pour s'attaquer au problème du manque et de la pauvreté parmi cette population. L'article examine donc comment l'agriculture à petite échelle aide à soulager le problème de la pauvreté dans les villes rurales et urbaines; plus particulièrement à travers la commercialisation des produits agricoles. Des données pertinentes ont été recueillies auprès des 356 répondants sélectionnés pour l

Abstract: The rate at which many marriages crash in Nigeria nowadays calls for serious attention. The effect of divorce on the couples concerned, their children and relatives is better imagined than experienced. This study therefore investigated the predictive potentials of infertility, socio-economic status, religious factor, premarital-cohabitation, sexual intimacy, age at marriage and in-law factor on divorce among couples in Ibadan. Two hundred and fifty divorcees responded to standardized instruments used to collect data. Seven hypotheses and one research question guided the study. Results showed that all the variables correlated positively with the criterion variable (divorce), and the research question revealed that the independent variables jointly contributed a total of 92.9% of the total variance for incidence of divorce. Recommendations were made to reduce the menace of divorce in Nigerian society.
Plasma copper status in hypercholesterolemic patients

African Journal of Biomedical Research , 2007,
Abstract: There has been inconsistent association between low copper (Cu) status and hypercholesterolemia (Hypercholesterolemia is a known risk factor in coronary heart disease). Most of these earlier studies have been predominantly in experimental models; very few reports have examined human subjects. We investigated the relationship between Cu status and hypercholesterolemia in human subjects and if this relationship is established it may be amenable to nutritional interventions. Seventy four (74) randomly selected plasma samples from patients on which cholesterol (Chol) estimations had been previously performed were included. The plasma samples were classified into three (3) categories according to the cholesterol concentration based on the reference range at UCH, Ibadan as at the time of analysis. The study groups included the following, hypercholesterolemic group (group1) (Chol level, > 250mg/dl), normocholesterolemic group (group2) (Chol level, 150 = 250mg/dl); and hypocholesterolemic group (group 3) (Chol level, 87- 149mg/dl). The mean values of Cu in groups 1, 2, 3 were 103.39±8.58 μg/dl, 122.67±14.69μg/dl and 123.82±10.15μg/dl respectively. The mean concentration of Cu in hypercholesterolemia was significantly different from the normocholesterolemia (p< 0.0001) and the hypocholesterolemia (p< 0.0001) respectively. The plasma Cu level of the hypercholesterolemic group was the lowest; while the levels in the normocholesterolemic and the hypocholesterolemic groups were similar. The low level of Cu in the hypercholesterolemic group was significantly lower than the levels in groups 2and 3 (p<0.0001) in both cases. There was a significant inverse correlation between cholesterol and Cu levels (r = - 0.4909; p< 0.0001). These data support some previous reports that hypercholesterolemia is associated with decrease Cu status and this may be manipulated to control hypercholesterolemia and associated disorders. (Afr. J.

Abstract: We study the recent patterns of antibiotic resistance in three geographically separated, and culturally and economically distinct countries – China, Kuwait and the United States – to gauge the range and depth of this global health threat, and its potential for growth as globalization expands. Our primary measures are the prevalence of resistance of specific bacteria to specific antibiotics. We also propose and illustrate methods for aggregating specific "bug-drug" data. We use these aggregate measures to summarize the resistance pattern for each country and to study the extent of correlation between countries' patterns of drug resistance.We find that China has the highest level of antibiotic resistance, followed by Kuwait and the U.S. In a study of resistance patterns of several most common bacteria in China in 1999 and 2001, the mean prevalence of resistance among hospital-acquired infections was as high as 41% (with a range from 23% to 77%) and that among community- acquired infections was 26% (with a range from 15% to 39%). China also has the most rapid growth rate of resistance (22% average growth in a study spanning 1994 to 2000). Kuwait is second (17% average growth in a period from 1999 to 2003), and the U.S. the lowest (6% from 1999 to 2002). Patterns of resistance across the three countries are not highly correlated; the most correlated were China and Kuwait, followed by Kuwait and the U.S., and the least correlated pair was China and the U.S.Antimicrobial resistance is a serious and growing problem in all three countries. To date, there is not strong international convergence in the countries' resistance patterns. This finding may change with the greater international travel that will accompany globalization. Future research on the determinants of drug resistance patterns, and their international convergence or divergence, should be a priority.In 1942, the first U.S. patient with streptococcal infection was miraculously cured with a small dose of penicilli

Global Journal of Health Science , 2012, DOI: 10.5539/gjhs.v5n1p28
Abstract: Tobacco smoking among the Aboriginal populations is a major public health issue in Canada. It remains a major contributory risk factor to the poor health status as well as years of potential life lost seen among the indigenous people. The use of tobacco has a spiritual importance to the people as a means of making connection to the Creator, but unfortunately tobacco smoking has taken a recreational aspect which has little or no connection with Aboriginal spirituality. The non-traditional use of tobacco is believed by the Elders to be disrespectful to the Aboriginal culture and traditional way of life. There is an increase in rate of use of smokeless tobacco as well as smoking of tobacco among the youth with increase in percentage among females. There are socioeconomic implications as well as adverse health effects of the misuse of tobacco on the Aboriginal people that need to be addressed. The healthcare professionals have a unique role in helping patients to reduce tobacco use within the community through programs that are culturally sensitive and relevant. Successful strategies requires general support from the community and it is very important that some of that support comes from community leaders, including spiritual, professional, administrative and elected policy makers.
Response Elicitation in English-medium Christian Pulpit Discourse (ECPD)
Taiwo, Rotimi
Linguistik Online , 2006,
Abstract: The study is an investigation into the various ways pulpit preachers in Christian religion elicit responses from their congregation. The data for the study consists of messages delivered from the pulpit at denominational, non-denominational and interdenominational Christian services in South-Western Nigeria. Working within the framework of Sociolinguistics and Discourse Analysis, the analyses reveal that preachers control the discourse, while the worshippers share in the process of creation of the text as it unfolds. For instance, they determine what responses are given, how they should be given and when to give them. It was also observed that response elicitation is done through the use of interrogatives, declaratives and imperatives, and such responses may come in forms of speech, physical action, and mental behaviour. Our analyses reveal a preponderance of spoken responses in the data. Five kinds of spoken responses are identified in the data, namely: Conventional Answer (CA), Response to Prayers (RP), Repeated Statements (RS), Gap Filling (GF), and Corrected Statement (CS). The study concludes that despite that the way responses are elicited depends largely on the practices of any religious community, certain patterns of elicitation are common in ECPD. The degree of control and the kind of response elicited by a preacher are determined by the language expectations of the community. Such expectations include knowledge of the language code, principles, norms, use, situation and the world of such religious communities.
