Objective: To determine the incidence and pattern of rape among students in a Nigerian tertiary institution. Method: A cross-sectional study was conducted among 400 students of Ebonyi State University, Abakaliki over a-two month period (between March 1 to April 30, 2014). A well structured self-administered questionnaire was distributed to them in sealed envelopes. These were answered in their privacies and returned sealed. Results: The response rate was 81.8%. The incidence of rape was 19.3%. 17.7% cases of rape occurred in fair-skinned females and only 1.6% occurred in dark-skinned females. Most of the cases of rape occurred in the age range 20-24 years, 12.5% and among the singles, 19.0%. Most rapes were perpetrated in the afternoon, 33.4%, followed by evening, 31.7%. 87.3% of victims recognized the rapists and could identify them. Most of the perpetrators of rape were relations of the victims, 60.3%. Most of the rape cases took place in the residence of the rapists, 48.6%, and the rapists were older than their victims in 100% of cases. 66.7% of victims did not make report to any person/authority and the commonest reason for not reporting was fear of shame and stigmatization, 70.6%. Conclusion: The incidence of rape in this study was very high. The victims of rape should be encouraged to open up. There should be legislation of stiffer penalties for the rapists.
In this paper we analyze the performance of two-way interference-limited amplify-and-forward relaying systems over independent non-identically distributed Nakagami-m fading channels. The lower bounds of the outage probability and symbol error probability are obtained. By using the derived lower bounds, three optimization problems namely, power allocation under fixed location for the relay, optimal relay position with fixed power allocation and joint optimization of power allocation and relay position were solved, for the case of Rayleigh fading. We proposed a method for compensating the effect of Carrier Frequency Offset on the system performance of amplify-and-forward relays.
The purpose of the study was to explore staff perceptions of organizational culture in their institutions and assess the impact of organizational culture on performance from faculty perspective. Data were collected from 80 faculty members from 3 non-faith based universities in Ghana. The study creates awareness and provides guidelines to non-faith based university colleges in formulating strategies to develop organizational culture types that empower faculty to work to achieve organizational goals. The findings showed that dominant existing achievement and support cultures impact positively on staff performance. The study contributes to the knowledge on organizational culture types and its practice especially in non-faith based private university colleges and their implications to performance. It also opens up the discussion on the place of organizational culture on performance in future research.
An experience was taken to the laboratory of Limnology of the CRSN/Lwiro in view to verify if fishes Barbus pellegrini would get acclimatized well in captivity and would consume larvas of mosquitos because well-known of entomophages, it of the 23/04 at 12/05/2014. To the term of this one, we noted a good acclimatization of our fishes in their surroundings of raising; larvas of mosquitos submitted to our fishes were consumed since the 6 hours of their submissiveness. When to what was to know how much of larvas a fish could consume, a variation in active number of 4 to 10 larvas in 24h was him. It has is sufficient 9 to 14 days so that develop himself of mosquito larvas in adults.
A systematic sampling of the aquatic macrofauna of the Kalengo River has been achieved of October 2011 to September 2012 in five stations according to the method Man-time. To the whole 56 species were inventoried, repartees in 7 groups taxonomies to know: Bugs (35 species, either 62, 5%), Mollusks (8, either 14,3%), Fishes (6, either 10,7%), Annelids (3, either 5,4%), the Plathelmintheses (2, either 3,6%), Crustaceans and Amphibians (1, either 1,8%). Bugs, Mollusks and Annelids were present in all sites and it during all year round of survey. The evolution of populations of the aquatic macrofauna during the period of survey, watch a certain stability of the total specific wealth and a better representativeness during months of April and June.
This research work investigated the firewall security and performance relationship for distributed systems. The relation between the security and performance efficiency is presented through different scenarios and the relationship between security and performance in firewalls is evaluated. Emphasis is on the relationship between network security and performance; the effects of firewalls on network performance. Various scenarios were evaluated through simulations using OPNET IT Guru Academic Edition 9.1 to show the effects of firewalls on network performance. The result shows that the network security does not have a direct correlation to network performance.
This paper provides a review and classification of the main regulatory reforms required in the fixed telecommunication segment. It also describes the methodology of the construction of a relevant measure of regulation. Precisely, we provide a description of the method of scoring of the individual regulatory reforms, as well as, the computation method of the overall regulatory index which aggregates the most applied regulatory reforms in the fixed telecom sector over the world. We collect data information from public sources including the regulatory data base of the International telecommunication Union (ITU) published in the year 2012 and contains regulatory information data for developed and developing countries in the world during the period from 2004 to 2011, as well as the database of the Plaut Economics. We complete the missing information data from the official reports that came from the regional and international organizations and the web sites of the National Regulatory Authorities (NRAs) of different countries considered. We are based on the scoring methodology of Zenhäeusern et al. (2007, 2012 a, 2012 b) to construct individual measures for the regulatory reforms adopted since the opening of telecommunication markets to competition. Our overall regulatory index, which aggregates these individual measures of regulatory reforms, permits to measure the intensity of regulation in the fixed telecom sector for 107 developed and developing countries during the period of 2004-2011.
The survey carrying on the effect of the cultural practices in the struggle against the bacterial withering of the banana tree (wilt) in Kadjucu South Kivu area has been led during fifteen months in order to value the effects of the ablation of the male inflorescence, the unstamped and the cut of the sick stumps while using the disinfected materials. For that, we considered three impacts of which 5 to 10%, 11 to 15%, more than 20% and three witnesses of which one for every impact. And the duration of propagation of Banana Xanthomonas wilt in field has been valued. The results show us that the cultural practices are efficient if the illness is again in the beginning. So one can manage the bacterial withering of the banana plants by the cultural practices if the impact is lower to 20%, but if the rate of attack is raised more it is recommended to practice the rotation of the cultures. The duration of propagation of Banana xanthomonas wilt between two banana trees on a same stump is of vicinity two months and a half. Therefore these results show that this illness cannot be eradicated by these cultural practices. It is recommended to suppress the sources of inoculums and to eliminate the risks of dissemination in the fields which are not reached.
Re-structure of public library is essential when its present state cannot meet the standard and objectives upon which it is been established. The purpose of the study is to know the extent of services rendered, state of information needs met and level of information resources available in Stella Obasanjo Library, Lokoja, Kogi State, Nigeria. Descriptive survey design was adopted. Instruments of data collection are questionnaire and personal interview. Questionnaire contains Table 1, 2, 3, 4, and 5 which were designed to obtain data from both library staff and library users. Eight (8) library staff answered questions in table 1: services rendered in their public library while, forty-seven (47) library users responded in answering questions in Table 2: types of information needs; Table 3: information resources needed; Table 4: available of information needed; Table 5: available of information resources needed. Data were analyzed in Table 1 by the use of criterion mean where ≥ 2.50 and < 2.50 are considered significant (considerable response) and not significant (inconsiderable response) respectively. Analysis shows that it is only leisure and recreation, and reading services are rendered to great extent, others are low extent except service with disadvantage groups that is rendered at no extent. Simple percentage was used to analyze Table 2, 3, 4, and 5 where above 50% and below 50% are considered agreed and disagreed respectively. Analysis shows in Table 2 that information needs of library users cut across agriculture, sports and games, health, property, politics, social, business, education, geographical and religion. On Table 3 it was discovered that information resources needed by library users includes all the itemized resources except audio and video conferencing, as well as audio cassette. From Table 4 it was discovered that 93.6% of library users do not have their information needs while, 6.4% did. Furthermore, in Table 5 it was discovered 80.9% of information resources needed by library users are not available while, 19.1% is available. Hence, from the data analyzed, the public library understudy need to be re-structured and the proffered recommendations will be of significant if adherent to.
For generations, man has kept studying and thinking about the communication capacity that could be established between machines and thought. This is an old dream, a fantasy that was not supposed to happen some day: pushing the limits of the human condition. Nowadays, advances in science make this dream almost come true. We always wanted to have any kind of super power, but now it gets really believable or possible. We are the first species to take control of our own evolution, not in the future but right now, thanks to artificial intelligence. Artificial intelligence is a new technology that allows an old fantasy to come true: improving the daily human and build machines that haunt the imagination of science fiction. Technologies of cognitive neuroscience have recently increased considerably and helped to advance the understanding of some mechanisms of the brain and human thought. This advance was made possible thanks to developments in the technology field and the computer science progress.
This paper presents a study on the description of eating behavior in humans, whose main objective is to know the current choice of Moroccan and study the influencing factors. This study is based on a structured questionnaire administered to a random sample of 100 respondents. This survey showed that the perception of a food is not only determined by its organoleptic properties but also by its nutritional properties and by social factors. These determinants are influenced by several factors including age, gender, level of education and specialization, health, and cultural factors. The results obtained confirm that the consumption patterns of individuals are not diversified; they are based primarily on the meats with a strong attraction to the sweet taste. Addictions and aversions were also the subject of this study. We found that all addictions and aversions emerged from childhood and addictive foods are mainly sugar products, coffee, and tea. These behaviors were governed by factors related to the individual and the environment
Nauclea diderrichii, is a forest species whose seeds germination is difficult in its biotope. Its overexploitation for its very resistant wood against the attacks leads to its disappearance in Togo. In vitro micropropagation trials were carried out for his faster and massive regeneration. In vitro seedlings apexes had been cultivated on four media (MS, ½ MS, WPM and ½ WPM). The high ionic concentration in macroelements in the culture medium is harmful to N. diderrichii's seedlings development. Complete Woody Plant Medium (WPM) (41,54mM) allowed a better growth of the seedlings during initiation phase. Among both cytokinins (BAP and Kinetin) used, BAP at 2 mg/L, has gave a better multiplication rate (13,65d ± 5.71 nodes/seedling). Among three auxins (IBA, NAA and 2,4-D) used at 0,1mg/L, IBA has gave seedlings with vigorous roots which are better appropriate for weaning, that those obtained with NAA. 2,4-D produced only calluses. The weaning of the seedlings, realized on vermiculite was succeeds at 100%. Thus fast and massive multiplication of N. diderrichii can be done in vitro on WPM added with BAP at 2 mg/L. IBA at 0,1mg/L is the auxin which is better appropriate for improvement of seedlings' rooting.
Environment is confronted with a variety of natural and synthetic organic compounds in its compartments, following rapid industrialization and urbanization. These continuously growing challenges elevate the need for implementing the clean and cost effective technologies. The plan of the present investigation is the copolymerization of natural and synthetic materials for the development of adsorbents followed by its application for the removal of environmental pollutants. Starch is selected as natural biopolymer and cyclodextrin represents the synthetic polymer. Both materials are copolymerized and further modified with the Cabbage fibres and epichlorohydrin as cross linker. FTIR analysis reveals the presence of cyclodextrin in the synthesized copolymer through stretching vibration of -CH2, -C-O-C at 2931cm-1 and 1016cm-1, respectively. On the other hand, starch based copolymer cross linked with epichlorohydrin is identified by the absorption band of epoxy group at 931cm-1. The presence of terminal and internal epoxy group at 763cm-1 and 669cm-1 also supports the synthesis. The SEM illustrated wider cavities that are expected to enhance the uptake capacity of modified copolymers for organic moieties. The inclusion complex of β-Cyclodextrin depicts rectangular features with milky white surface. The samples were scanned 10-71 of 2θ by steps of 0.015 with Cu K α radiation (λ = 1.54059) operating at 40 kv and 100 mA. The synthesized Copolymers were applied as adsorbents in a batch experiment to determine efficiency for the removal of a wide range of environmental pollutants. The results of UV-Vis disclosed that crystal violet and congo red is removed to a comparable extent. Atomic absorption analysed the Lead (85-95%) is more efficiently removed than Chromium (60-70%). It might be related to higher molecular weight of the former than the later. Similarly, the fused aromatic rings demonstrated less removal for pyrene (202.25g/mol) than anthracene (178.23g/mol). The synthesized copolymers were also applied for the adsorption of PCBs from transformer oil to present model of in-situ remediation.
Mathematicians have tried to establish algorithms or formulas to solve the algebraic equations of the type of p(x) =0, where p(x) is a polynomial in x of degree n with real coefficients. That has been possible for n≤4. However, for n≥5. Abel proved that, in general, we cannot find formulas of resolution by radicals. Thus, mathematicians did not focus on the search of the resolubility condition any more by radicals of an algebraic equation of the n>5 degree. The present study discusses the theory of methods or the knowledge foundations on the algebraic equations. We also suggest the resolution of algebraic equation of n≤4 degree, and present the methods of resolution of the cells (equations) of the degree greater than or equal to 5 (n≥5) in the set of complex numbers.
In recent years, the usage of the object oriented paradigm in software development has increased. Consequently, by using object oriented software, new elements have been added to software development process. The design phase is the backbone to develop any object oriented software. Therefore, the object oriented metrics are used to measure the quality of design. This paper describes a framework for evaluating the object oriented design. The framework relates the design properties such as: Encapsulation, Coupling, Cohesion, Abstraction, Complexity, Composition, Messaging, Inheritance, Hierarchies, and Polymorphism to high level quality attributes such as Reusability, Effectiveness, Extendibility, Understandability, Correctness, and Flexibility. Meanwhile, the design properties in classes are defined to be assessed by using a suit of object oriented design metrics. An empirical data is collected from four case studies to calculate the metrics and then apply them to calculate the quality properties.
Pathogenic bacteria transmitted to humans through water are, nowadays, responsible for various infectious diseases; mainly gastrointestinal. Several disposal methods for these pathogens, such as chlorination, ozonation, and UV Rays have been used and developed. Our study consists of using a new approach to deal with resistant strains that exist in wastewater; by the application of synthetic materials, the potassium permanganoferrates K3FexMnyO8 (1≤x/y≤4). Our results show the antibacterial effect of these products tested in liquid and solid medium depending on the pH on three bacterial strains: Pseudomonas aeuruginosa (Ps.Ae), Escherichia coli (E.Co) et Staphylococcus aureus (St.Au.). In the presence of the potassium permanganoferrates, bacterial growth decreases by half in the liquid medium, with concentrations going from 0.74 mmol/l up to 0.023 mmol/l, depending on the Fe/Mn ratio and on the studied bacteria. In the solid medium, the inhibitive efficiency of K3FexMnyO8 is also demonstrated for optimized concentrations, between 0.74mmol/l and 0.023mmol/l. The maximum inhibitions in the liquid medium are 99.4% for E.Co. and 99.9% for St.Au., are obtained with concentrations of 0.5 mmol/L of K3FexMnyO8 (Fe/Mn=4). However, with 1.2 mmol/l of permanganoferrates, the inhibition doesn't exceed 98.8% for Ps.Ae.
The adsorption of an endocrine disruptor in the paraben family, (butyl paraben), from water resources on activated carbon has been studied. The activated carbon was prepared based on coconut shells considered "agricultural waste" in Côte d'Ivoire. The influence of both parameters on the effect of adsorption (the mass of the activated carbon and the pH of the reaction medium) has been studied. It is clear from these studies that the higher the amount of activated carbon is, the better is the amount of butyl paraben remove from water. Moreover, the adsorbed amount is much higher in an acid medium. Adsorption of activated carbon on butyl paraben follows the Langmuir, Freundlich and Temkin models because uptake is gradual monolayer to higher layers. The equilibrium parameters k and 1 / n less than 1 indicate that the adsorption of butyl paraben on charcoal-based coconut shells is favorable. Adsorption of activated carbon on butyl paraben fit a second kinetic order as shown in representation of t / a versus time; with a thermodynamic constant of 0.1091 g.mg-1.min-1.
The acacia is a kind of tree with a rapid growth. It is now used in Cote d'ivoire, by the National Center of Agronomic Research (CNRA) through its program "Forest and Environment" to fight against the deforestation and to produce, of the charcoal mainly. But, in order to value this Ivorian biomass too, some activated carbons have been prepared by charcoal, from two species of Acacia (auriculiformis and mangium) following the chemical mode of activation with H3PO4. The adsorbent properties of the activated carbon samples obtained have been studied. These properties have been studied from the isotherms of adsorption of the methylene blue (MB). This allowed determining the types of adsorption: the isotherms of adsorption on the activated carbons auriculiformis are of type L and are compatible with the model of Langmuir and that of Freundlich. The isotherms of adsorption on the activated carbons mangium are of type S, and do not describe in a satisfactory way the model of Langmuir, nor that of Freundlich. The results obtained by adsorption of the MB on the different activated carbons permitted showing that, the carbon auriculiformis activated to 800°C, during 6 hours (CA-A6-800), is the most effective of all the activated carbons, for the elimination of this dye.
Discriminant analysis of the problems involved in the classification of one or more individuals in one or another of a series of pre-defined groups. This is a statistical method for studying the differences between two or more groups of individuals or objects by considering several metric variables simultaneously. The discriminant analysis used to build a predictive model of allocation based on observed characteristics of each individual group. We will use this method to analyze a sample of customers taken from the marketing department of an industrial company in the region of Casablanca.
Linear programming is a very important tool for operational research. It is a generic tool that can solve many problems in engineering management. Indeed, once a problem modeled in the form of linear equations, methods ensure solving the problem exactly. Data and information needed to solve the problem and are assumed known in a certain way. The aim of this paper is to compute a linear program of production of an industrial company.
A control chart is a tool used in the field of quality control to control a process. It determines when a particular cause of a characteristic variation occurs, resulting in alteration of the process. For example, a manufacturing process can be switched off before producing non-standard components. The types of control charts most commonly used in the industry are control charts of the average and range. In this method, two graphs are plotted and interpreted simultaneously. Another type often used in economics, is the control chart for individual values. The aim of this paper is to construct a control chart of production processes of an industrial company.
This research work was undertaken to evaluate the problems of Information Security Risk Management of Ibrahim Babangida Library (IBL) of Modibbo Adama University of Technology, Yola. The data for the study were obtained through a structured questionnaire and personal interview from the four Units of the library namely: Readers' unit, serial unit, Reserve Unit and Media Unit. The analysis employed was the Analytic Hierarchy Process (AHP) to prioritized threats in four Units of the library. The analyses of data revealed that: Library Security Threats in IBL are Categorized into three; Technological Threat, Natural Threat and Human Threat. Human Threat is the most severe among the three. Based on this result we gave the Recommendations that management should allocate resources to mitigate information security threat in order of threat preference: Human threat, Technological threat and Natural threats respectively.
There is no doubt that decentralisation has acquired a prominent place in the development policy debates but unfortunately it cannot be a panacea for all development ills .To many, decentralisation of governments and planning is a self-evidently good thing. It will avoid the ills of over-centralization such as insensitivity to local conditions and will also bring fuller organization and participation at sub national level. Decentralisation is viewed as providing an outline which enables lower level units of governance to execute duties and get benefits from natural resources in line with the subsidiary principle. The subsidiary principle posits that duties which can be performed at the local level should be devolved to the local level. Decentralisation seems to combine appeals for planning and democracy. Can it live to these hopes in reality? The limits to government decentralisation include its need for manpower, finance and technical demands. Functional and territorial decentralisation has been blanketed into conflict between objectives of equity, growth, coordination, participation and national integration. The study used participant observation and literature review. One of the conclusions of the study is that there is a need to strengthen a more democratic and accountable local government in order to be able to implement the decentralized responsibilities. The apparent consequence of devolution is that the central government would be left with core responsibilities such as foreign affairs. Devolution would enable the people of Mashonaland East Province in Zimbabwe to report their needs to Marondera, the provincial capital rather than Harare. The assumption is that authorities at those administrative seats would respond much faster and with greater sympathy and empathy than those in Harare. The Government would be closer to the people and it would be the people themselves in both fact and effect. However, one major risk with decentralisation technique is that many private organisations are profit-oriented and may rip off the state.
A number of people in the world do not understand the reasons for studying Geography mainly because apart from academia there are no other people employed as geographers, therefore the question of why one should study geography is a valid question. Nevertheless, geography is a multidisplinary subject that has a myriad of career options in areas ranging from meteorology to disaster management. With geography one is equipped with a holistic understanding of the earth and its systems in totality. This include issues such as climate change, global warming, desertification, El Nino, water resource issues, among others including the understanding of global political issues that occur between countries, cultures, cities and their hinterlands, and between regions within countries. This is particularly important in a world that is gradually becoming smaller (globalisation). The study of world regions i.e. culture, foods, language, religion and landscape helps in understanding of our world. This is particularly important because, those who choose to study geography will learn to think critically, research, and communicate their thoughts through writing and other means of communication independently. They will thus develop skills of graphicacy, measurement, analytical, mathematical and leadership skills. The study of geography should be enhanced since it provides students with knowledge about our rapidly-changing world and how humans are impacting our planet including plenty career opportunities associated with the subject.
At the time of harvest, most foods are likely to contain contaminants, to have components which are inedible or to have variable physical characteristics (for example shape, size or colour). It is therefore necessary to perform one or more of the unit operations of cleaning, sorting, grading or peeling to ensure that foods with a uniformly high quality are prepared for subsequent processing. This paper examines the role of unit operations in agricultural products processing. The study adopted a desk review of existing literatures on unit operations in processing. Benefits of food processing include toxin removal, preservation, easing marketing and distribution tasks, and increasing food consistency. In addition, it increases seasonal availability of many foods, enables transportation of delicate perishable foods across long distances and makes many kinds of foods safe to eat by de-activating spoilage and pathogenic micro-organisms.
This work aims to describe the importance of FMECA (Failure Modes Analysis of Effects and Criticality) through a case study conducted in several industrial companies; and it is in a process of quality and maintenance. The FMECA is an Analysis of Failure Modes, Effects and Criticality. It is a technique of analysis by examining the causes of failure of the elements of a system to achieve the effects of this system. This method can be applied to a product, but also to a method or a means of production. The purpose of the FMECA method is to increase the quality of a product or process. She does not mind the definition of a need or validation product / market
In 2011, the State of Cameroon took measures in view of the transfer of competence in matters of refugee status determination (RSD) from the United Nations High Commission for Refugees (UNHCR) to the national authorities by passing a decree on the organization and functioning of refugee status management organs. This work questions and evaluates measures that have been taken by the State in order to ensure that RSD will be carried out fairly when it shall take over. It proceeds by studying the various legal instruments that have been adopted by the State to govern future refugee status determination activities. The work arrives at the conclusion that measures taken to ensure fairness and impartiality in refugee status determination are insufficient and makes recommendations to this light. It however maintains that in spite of foreseeable shortcomings, it is important that the transfer of competence in matters of refugee status determination takes place since it relates to State sovereignty.
This paper is a criticism of the theory according to which the primary aim of literature is to give pleasure, and literature does not teach anything new to human beings. The paper first attempts to place the triad literature-pleasure-ethics in a wide context of literary-critical and rhetorical debates that span centuries, from the Antiquity to the modern times. Then it proceeds to a critical examination of this doctrine of the primacy of pleasure over ethics in literature. In the end, it posits that there is no opposition between pleasure and ethics: literature only delights as it instructs. But inasmuch as ethics is the core layer, and pleasure the surface layer of literature, the former overrides the latter, and so reading involves moving from the outside to the inside of a work.
We are living in a period where public opinion is unanimous in the defence of Human Rights, as the protesters are always far outnumbered by the partisans. This paper neither takes a side nor acts as a judge in disputes between supporters and protesters, but offers a constructive criticism of the theory and praxis of Human Rights. Thus, in an attempt to extend the scope of traditional criticism whose only target was the concept of 'Right,' this essay reflects on the essential identity of Man, the beneficiary of the Rights. It walks in the footsteps of Levinas in the laying of the practice of the 'unconditional duty to the Other' as the foundation of Man's Humanity and as the objective foundation of the Rights.
The development of sophisticated material for application in dentistry has become a crying need at the present age. Although a significant numbers of materials including metals, ceramic, polymers, composites and now some nanocomposites exist for current and potential applications as dental implants, restoration and filling tooth roots, further rigorous research works are essential to make these promising materials commercially available as well as clinically feasible. However, mechanical properties, biological compatibility and antibacterial properties play vital role in determining the suitability of a particular material to be used. This review focuses on some newly developed potential dental materials in terms of their compatibility issues, sustainability in bacterial attack and mechanical characteristics. In addition, the limitation of the material and further research on it will also be discussed.
Data processing technology is ever necessary to support the business of the company, and it is housed, kept, and replaced by new technology when available to satisfy the growing thirst for information processing power led by the company. Due to the complex nature to maintaining large computer systems and software's good IT policies are required to run the organization. The expectations are evolving now that IT should be a major contributor to the trade mission of the company. IT managers often do not understand the technology hidden powers and aspect for the freedom and accurate working, which can be provided with the existing resources. It not only it serves the business, but it turns into the proper application of technology as well. In fact, it is a small, but nevertheless significant paradigm to make the transition from a culture of technology to a working convenience. IT Service Management has been used in the IT industry for many years in one form or another, usually by organizations have realized the need for an approach to the provision of balancing services within IT. It is based on the principle of defining, achieving and maintaining the required service levels for IT user, business and company at large. Unfortunately, it can be said that very few IT organizations have adopted IT as a key strategy for Freedom of Information for meeting the targets set in the larger company. Even the adoption of the IT model many organizations have left behind a service orientation, while in their struggle for control of new technologies and therefore that are immature in proper information freedom.
Our goal is to determine whether and how the drug affects the survival time, comparing the survival curves of two groups of 21 patients, the first being treated, and the second component the control group. In the 6-MP group, only 9 patients showed a relapse, while 12 others were "censored" (cure or lost sight of by the leaders of the study). In the control group all relapsed. This is achieved by using the survival model and the Kaplan Meier.
Hydrogeochemical evaluation of groundwater quality of Abakaliki and its environs was carried out on a scale of 1:25,000. The concentrations of selected metals in 25 groundwater samples namely Fe, Pb Zn, Cu, Mn, Co, Ni, Ba, Ag and Cd were determined using Atomic Absorption/emission Spectrophotometer (AAS) 205model. The pH of the sample were determined using a handheld digital pH meter 350 model. The pH values ranged from 6.1-7.0 indicating that the samples are slightly neutral. Analysis for physico-chemical parameters and variables (ANOVA) was done using standard methods. StatistiXL 1.5 was used for performing the grouping. Chemical analysis and various concentrations of the heavy metal loads show that the groundwater has little or no trace of Fe (0.01mg/l) Cu (0.03mg/l) Zn (0.02mg/l) Pb (0.01mg/l) and Co (0.02mg/l) contamination. The concentrations of Fe (0.03 mg/l) Pb (0.01 mg/l),Co(0.03mg/l) and Zn (0.02mg/l) were in compliance with WHO (2011) permissible standard for drinking water while the concentration of Cd ranged from 0.11mg/l to 0.14mg/l and silver 0.06 mg/l to 0.08 mg/l are far above World Health Organisation standards indicating that the area are moderately contaminated with Cd and Ag. The hydrogeochemical analysis carried out during this study stands as a guide to the best sustainable management of some contaminated aquifer systems of Abakaliki and environs. Statistical analysis of variance (ANOVA) revealed that Fe, Cu and Co were significant at P<0.05. The analysis reveals that the concentration of the various heavy metal load in the study area decreases away from the source point as in areas near to the Ricemill husk/cluster.
This paper aims to review the various technologies behind wearable biosensors and where there are areas for improvements to be made. The theoretical foundation of this paper was formed by conducting a comprehensive literature review on wearable biosensors. There are three main biosensor technologies that are presented in this paper. The three main wearable biosensor technologies that are most prominent include accelerometers and motion sensors, biochemical sensors, and photoplethysmographic sensors. The empirical research that was used is limited to 15 papers from relevant conferences and journals associated with the medical device industry. Wearable biosensor technologies clearly have several clinical applications that make them one of the most appealing tools in the medical device industry. This paper illustrates that wearable biosensor technologies definitely have the capability to make a significant impact on the medical device industry because of their compact and diverse nature.
The present study encompasses an assessment of annual and long term variations in groundwater level of Peruvanthanam and Valiyathodu sub-watersheds and its correlation with rainfall occurrence. The seasonal variations in phreatic surfaces of both sub-watersheds reveal that unlike Peruvanthanam, Valiyathodu sub-watershed shows maximum fluctuations in groundwater level during post monsoon season. Average rainfall in Peruvanthanam sub-watershed during this period was 3832.28 mm and the average water levels in the observation wells CGWBp1 and CGWBp2 were 4.86m and 2.62m respectively. In 2007 when there was an increase of 1199.72 mm rainfall from the average. Well no. CGWBp1 shows a decrease in water level from 4.36 to 4.10m ie, 0.76 m (15.64%). The corresponding decrease in value observed in groundwater level of well no CGWBp2 was from 2.62m to 2.20m ie, 16.03%. When both the well data are compared, greater variations are observed, in well no.CGWBp2 during increase in rainfall. This is a reflection of the greater porosity and permeability of the ground material in an around the well. Similarly in 2000, there was a decrease of 1296.78mm in rainfall from the average. In well no CGWBp1 there was an increase in depth from 4.86m to 5.59m ie, 0.71m (14.61%). The corresponding value for well no CGWBp2 was from the average value of 2.62m to 2.95m ie, 0.33m (12.60%). Average rainfall of Valiyathodu sub-watershed was 4099.82mm and the average water level in CGWBv1 and CGWBv2 are 9.12m and 5.64m respectively. In 2005 when there was an increase of 1031.68mm rainfall from the average well no. CGWBv1 shows a decrease in value from 9.12 to 7.82 (14.25%). The corresponding variations observed in well no. CGWBv2 was from 5.64m to 5.16m (8.51%). In 2002 there was a decrease in rainfall to 3089.00mm from the average value of 4099.82mm. The variation in groundwater level observed in well no. CGWBv1 in accordance with this is from 9.12m to 10.01m ie, 0.89m (9.76%). The corresponding variations observed in well no. CGWBv2 is from 5.64m to 5.98m ie, 0.34m (6.03%). When both well data are compared, greater variations are observed in well no CGWBv1 during both increase and decrease in rainfall. This shows that sub surface phreatic aquifer material in around well no. CGWBv1 has more permeability compared to CGWBv2.
