Transmission of critical data in ubiquitous healthcare solutions requires a high degree of reliability. Literature on several threats to uninterrupted data transmission and suggested schemes to avoid them or minimize their effect are available. Denial of Service is one of the severe attacks which can result in complete failure of the network connectivity in terms of no service error. It is therefore crucial to detect such attack and deploy schemes which can recover the connectivity and access to services. This paper discusses the instances, effect and mitigation plans for a network under the Denial of Service (DoS) attacks in healthcare environment. The aim of this paper is to evaluate the multiple methods and shows how the Multi-homing feature of Stream Control Transmission Protocol (SCTP) can be exploited to combat DoS attacks. The performance analysis of suggested methods during DoS attack has been studied in terms of network metrics such as received packets, dropped packets, packet drop rate and throughput using Network Simulator 2 for electronic health (e-health) and mobile health (m-health) applications. The Simulation results indicate that the proposed multi-homing SCTP (MH-SCTP) framework improves the performance significantly in terms of meeting the quality of services (QoS) requirements under the DoS.

The idea of the existence of connection between the development of society and the media was expressed in the middle of the XX century by a Canadian scientist, a representative of the University of Toronto, Harold Innis. In short, the essence of the idea of Innis is that since the early stages of development the ruling elite in all countries has controlled the information. Innis\'s ideas were supported and developed by Marshall McLuhan and Walter Ong. A lot of attention to this issue is paid by our Russian scientists as well.\nSince Peter the First, power in Russia has always tried to control the production of information. Domestic printing and publishing were controlled by censorship, which became a special state institution. Only for a short time in 1917, from the February revolution till the October one, the activities of the media in Russia were carried out freely. After the Bolsheviks came to power, those media which did not support the \"new power\" were closed. Then again, almost for 70 years censorship reigned being carried out by General Directorate for Literature and the Press (Glavlit) established by the Bolsheviks.\nIn 1991 the Soviet Union collapsed. Russia adopted the \"Law on Mass Media\" which gave all citizens the right to freely produce and disseminate information and to establish any media. But \"romantic\" period in the activities of Russian media lasted only a few years. They again became dependent on major corporations and the state. Thus, the authorities regained control over the activities of Russian media.\nBut not only in Russia power strives to use the mass media for its own interests. This happens in other even older democracies. Today the abilities of the media are used by many countries as an instrument of propaganda impact on the population.\nThe author of this article based on the realities of the political processes in Russia justifies the need for state control in the sphere of information considering the onset of new challenges and threats faced by the modern state. But the state must take into account the interests of all participants in information work, providing the public with the opportunity of communication with authorities on all relevant issues.

Abstract:\n Adhesive layer is an essential part of tooth colored restorations which play an important role in decreasing the microleakage between the tooth and restoration material after polymerization shrinkage, the purpose of this study was to evaluate the effect of deferent adhesive system of bonding agent on microleakage of nanocomposite resin in class II cavities. Two different types of adhesive systems: universal adhesive (ExciTE) and a newly developed adhesive (Nano-Bond) and one type of light-cured resin restorative material (nanocomposite resin) were used in this study. These adhesives were applied to prepared tooth cavities by either manufactures’ instructions or by an experimental method (single or double application). Nanocomposite resin was then placed and light-cured for 40 seconds. Teeth were subjected to 500 thermal cycles between 5 °C and 55 °C and were immersed in 3% methylene blue solution for 24 hours; microleakage was observed microscopically. The data were analyzed by a two-way ANOVA. For comparison between groups, Tukey’s post-hoc test was used.\n Nanoparticles reinforced adhesive system shows low microleakage in compare with universal adhesive system, application of two adhesive layers also can decrease the microleakage, the ability of stress absorption by adhesive layer after polymerization shrinkage of restoration material will reduce the microleakage.

Hydroxyapatite (HAP) was prepared from catfish bones at optimized conditions by employing Central Composite Design (CCD) under Response Surface Methodology (RSM). The temperature of preparation ranges between 300 and 1000 0C and time was varied between 1 and 2 h. The software gave thirteen (13) runs experiment within the conditions. 10g of treated catfish bones inside crucible was calcined in the furnace at the temperatures and times suggested by the software. The yield percentages were determined and a standard method of pore size estimation Methylene Blue Number Method was used to estimate the adsorption capacity of the calcined catfish bones (CFHAP). Hence, the optimized conditions for adsorption were deduced. Characterization of the catfish bones before and after calcinations was studied by using Scanning Electron Microscopy (SEM); Fourier Transform Infrared Spectroscopy (FTIR;) Energy Dispersive X –ray Spectroscopy (EDX) and Brunaver-Emmett-Teller (BET). The results confirmed that the product is hydroxyapatite.

the present research analyzes the inflation-unemployment equations as well as the effects of required reserve ratio on money growth and inflation. Such that, initially the relationship between each of the variables is determined and then according to a new equation, the effect of the equation on inflation-unemployment equations is applied by solving differential equation. The results show that there is a negative relation between the required reserve ratio for banks with inflation rate and money growth and the type of inflation and its path is seen by replacing these relations in the equations of inflation-unemployment and the last result of this issue is that the banking based on the principle of the fractional reserve leads to severe fluctuations in inflation, which may be irreparable.

In this paper, we used two data fusion methods, say, the data fusion method of using radial basis function with Gaussian kernal and the data fusion method of using radial basis function with hybrid Gaussian kernal to analyze the data for portable pesticide detection. By comparing these two methods, we obtain that the method of using radial basis function with Gaussian kernal is better for predicting data for portable pesticide detection.

Limited access to complete cassava processing information has affected the motivation to farm, and the quantity of Cassava harvested annually in Nigeria. Some of this vital information is found mostly in tacit knowledge of the experience farmers, in manual records at the agricultural extensions, Federal government ministries/agencies, States agriculture department leaflets, on radio and television agricultural programs. Limited access to cassava information is mainly due to the unstructured and diverse format, lack of awareness by the farmers, whom mostly, are based in the rural settings. Thus, the need to provide important cassava and other agricultural information to the farmers cannot be overemphasized. To enable cassava farmers to meet their goal of bountiful yield and quality production; cassava knowledge should be provided both in a generic and context-specific manner. One way to address this limited access and information sharing on agriculture is to develop cassava ontology, which specifically addresses entire cassava processes. The proposed ontology will integrate local characteristics regarding culture, language, climate, market, and cassava plant varieties The farmers desire for context-specific information prompted the design for a knowledge base for cassava crop. This study presents a database with contextual information and ontological approach designed to meet information needs of the cassava farmers. Presently, no cassava ontology or any other related tubers have been constructed in Nigeria. We believe this study would guide the construction of other crop knowledge base, in Nigeria and the domain of agriculture.

Twenty homeless people were interviewed about the nature and frequency of their victimization experiences and fear of crime along with their past and current criminal justice involvement. Although this is an exploratory project we have preliminary results which forms the basis for more rigorous evaluative studies in the future.
