In this paper, a deterministic mathematical model for the transmission dynamics of infectious diseases among infants in a vaccinated and temporary recovered population is proposed. Although the equilibria of the model could not be expressed in closed forms, the existence and threshold conditions for their stabilities are theoretically investigated. The standard dynamical modelling methods are used for analyzing the behaviours of the solutions both at the disease free equilibrium and the endemic equilibrium. In addition, the conditions of the parameters for the disease free and endemic states are obtained through the basic reproductive number. The results of this study guide the way to reduce the disease outbreak among the infants.

Cognitive radios hold tremendous promise for increasing spectral efficiency in wireless systems. The spectrum sensing problem has gained new aspects with cognitive radio and opportunistic spectrum access concepts. It is one of the most challenging issues in cognitive radio systems. A cognitive radio is an intelligent wireless communication device that exploits side information about its environment to improve spectrum utilization. Spectrum shortage was born the idea for cognitive radios. These devices utilize advanced radio and signal processing technology along with novel spectrum allocation policies to support new wireless users operating in the existing crowded spectrum, without degrading the performance of entrenched users. In this paper we present a Cognitive Radio approach for usage of Virtual Unlicensed Spectrum , a vision of a Cognitive Radio (CR) based approach that uses allocated spectrum in a opportunistic manner to create “virtual unlicensed bands” i.e. bands that are shared with the primary (often licensed) users on a non-interfering basis. Dynamic spectrum management techniques are used to adapt immediate local spectrum availability. One of the most important components of the cognitive radio concept is the ability to measure, sense, learn, and be aware of the parameters related to the radio channel characteristics, availability of spectrum and power, radio’s operating environment, user requirements and applications, available networks (infrastructures) and nodes, local policies and other operating restrictions. In cognitive radio terminology, primary users can be defined as the users who have higher priority or legacy rights on the usage of a specific part of the spectrum.

The rapid growth of the internet and the World Wide Web has led to the development of pharmacoinformatics technologies to assist oncology healthcare professionals in delivering optimum pharmaceutical care and health related outcomes. There is an increasing recognition that information technology can be effectively used for drug discovery. The work in pharmacoinformatics can be broadly divided into two categories - scientific aspects and service aspects. The scientific component deals with the drug discovery and development activities, whereas the service oriented aspects are more patient centric. Pharmacoinformatics subject feeds on many emerging information technologies like neuroinformatics, immunoinformatics, biosystem informatics, metabolomics, chemical reaction informatics, toxicoinformatics, cancer informatics, genome informatics, proteome informatics, biomedical informatics, The minimizing the time between a drug‘s discovery and its delivery to the marketplace and maintaining high productivity in the manufacturing processes. During a product‘s lifecycle many complex decisions must be made to achieve these goals. To better support the development and manufacturing processes at each stage, we have proposed a new epitome to facilitate the management and transfer of data information and knowledge. In future these information technology efforts are expected to grow both in terms of their reliability and scope. Thus, this emerging technology (pharmacoinformatics) is becoming an essential component of pharmaceutical sciences.

The issue of teacher supply and demand amidst the call to meet Universal Primary Education (UPE) remains one of the critical issues facing developing countries today. The problem is compounded by a number of factors that vary from region to region. The main purpose of this study was to examine the factors influencing teacher supply and demand in Old Kajiado District in Kenya. The study employed survey research design. Stratified simple random sampling procedure was used to arrive at forty two (42) schools and head teachers respectively, one hundred and seventy one (171) teachers and nine (9) staffing officers. Questionnaires and interview guides were used to collect data. Data were analysed with the help of SPSS version 16.5 for windows. The study revealed that there a number of key factors that influenced teacher supply and demand in the District. These included policy related issues on staffing, deployment and transfers. Other particular issues were hardships in terms of harsh climatic conditions, poor infrastructure, poor teacher facilities and cultural related issues like perception of women professionals. The study suggests participatory approach in addressing the problem of teacher supply and demand which may differ from one place to another.

This is the study to evaluate the performance of new design of biogas unit and to enhance the biogas production by using different parameters. The raw material to be fed in digester will be the food waste which gets generated everyday from restaurant full of crowd in the locality. With this unit, biogas equivalent to two kg of LPG can be generated from the feeding of approximately 15 kg of food waste every day. This is the only design available which allows the user to choose how much biogas pressure he wants. Biogas thus produced can be checked for quality by different inoculums and additives. Thus the cost of disposing the food waste can be saved and the energy can also be recreated and reutilized for restaurant benefits. Hence the atmospheric contamination automatically gets prevented.

Pain is an unpleasant sensory and emotionaly associated with actual or potential tissue damage. Pain acts as a warning signal against either in the body or in the external environment of an individual. Pain control is a major issue in dental practice. There are several types of medications that are used to manage dental diseases. The medications discussed in this article have pharmacological properties that are used to treat conditions such as pain, anxiety and inflamation.

Internet of Things (IoT) is a significant idea of another innovation era. It is a dream that allows the sensors or implanted gadgets to be interconnected over the Internet. The up and coming IoT will be significantly exhibited by the tremendous amount of heterogeneous organized installed gadgets that create seriously "Huge information".

This paper organized as such: In the first section authors mention about all aspects of cloud computing – basic definitions, benefits, important features, workability and application, and so on. In the second section of this paper, authors mention Microsoft decisions about applying of cloud computing onto their newest products, such as Azure OS. In the third section of this paper, authors reveal new innovative algorithm for overcoming malfunctions and spyware actions from cloud platforms and resources. In this section, they purpose a new adaptively reduced-order extended Kalman filter for using as an estimator and predictor in cloud platforms. Authors claim that, if this algorithm were implemented on cloud gateways and resources, cloud service providers were able to track and trace lots of spyware and Trojans and also predict and estimate amount of power consumptions.

In this letter, the fractional modified decomposition method has been implemented for solving nonlinear sine-Gordon equation of fractional order. The fractional derivatives are described in the Caputo sense. In these schemes, the solution constructed in power series with easily computable components. The method is powerful tool for obtaining analytic and approximate solutions for different types of fractional differential equations.

As an academic discipline, business ethics emerged in the 1970s. Since no academic business ethics journals or conferences existed, researchers published in general management journals, and attended general conferences. Over time, specialized peer-reviewed journals appeared, and more researchers entered the field. Corporate scandals in the earlier 2000s increased the field's popularity. As of 2009, sixteen academic journals devoted to various business ethics issues existed, with Journal of Business Ethics and Business Ethics Quarterly considered the leaders. Business ethics (also corporate ethics) is a form of applied ethics or professional ethics that examines ethical principles and moral or ethical problems that arise in a business environment. It applies to all aspects of business conduct and is relevant to the conduct of individuals and entire organizations. Business ethics has both normative and descriptive dimensions. As a corporate practice and a career specialization, the field is primarily normative. Academics attempting to understand business behavior employ descriptive methods. The range and quantity of business ethical issues reflects the interaction of profit-maximizing behavior with non-economic concerns. Interest in business ethics accelerated dramatically during the 1980s and 1990s, both within major corporations and within academia. For example, today most major corporations promote their commitment to non-economic values under headings such as ethics codes and social responsibility charters. Adam Smith said, "People of the same trade seldom meet together, even for merriment and diversion, but the conversation ends in a conspiracy against the public, or in some contrivance to raise prices.
