The spherical bodies are arranged in a multilayer manner within a cylindrical channel through which hot air flows with different volume flows. In this way, the spherical bodies form a porous fluid-heated medium, in this case air. The cylindrical hollow channel is thermally insulated so that the inlet heat of the fluid is converted to the heating of the spherical bodies and the heat output from the cylindrical channel. An infrared thermographic camera generates a thermogram of the porous medium of the outlet of a cylindrical channel, while directly measuring other process parameters. On the one hand, mathematical modeling determines the relationship between the effective temperature and the effective emissivity of a porous medium at different fluid flow rates and different emissivity of spherical bodies. The established methodology, mathematical modeling and infrared analysis give the possibility to determine the effective emissivity and the effective temperature of different porous structures.

The threat posed by seismicity anywhere in the world is one that can never be completely dismissed. While it is generally accepted that earthquakes will predominantly occur along plate boundaries, devastating earthquakes have been recorded in the interiors of tectonic plates. Zambia, located in the interior of the African plate may generally be assumed to be aseismic. However, the influence of the East Africa Rift System challenges such an assumption.The research aimed at establishing Seismic hazard in Zambia, as regards structural design of infrastructure. The research methodology included literature review of works related to seismicity and geology of Zambia and the sub-region and analysis of raw earthquake data obtained from earthquake monitoring agencies. The research established significant values of peak ground acceleration (PGA) of up to 0.5g and 0.7g for return periods 475 and 950years, respectively, in some seismic source zones. It is recommended that seismic hazard be given due consideration in structural design, especially for lifeline and critical infrastructure.

The paper 'AugReality' introduces the technology of augmented reality for Android phones. This application is useful when the user is in a strange location. The system provides a user friendly environment with the location specific details. Augmented Reality (AR) is a live direct or indirect view of a physical, real-world environment whose elements are augmented (or supplemented) by computer-generated sensory input such as sound, video, graphics or GPS data. It is related to a more general concept called reality. In which the view of reality is modified (possibly even diminished rather than augmented) by a computer. As a result, the technology functions by enhancing one's current perception of reality. By contrast, virtual reality replaces the real world with a simulated one. Augmentation is conventionally in real-time and in semantic context with environmental elements. With the help of advanced AR technology.

Due to the globalization of the economy, organizations have intensified their search for strategies, which provide them with a continuous and sustainable competitive advantage. Such strategies often result in actions and plans that define how organizations improve the goods and services they product and differentiate them in order to take into account the diversity and the needs of their customers. This is notably the case of knowledge intensive services-oriented organizations where services delivered to customers do not have the same legal protection as material goods. Banks, insurance companies, and software industry are examples of such organizations, which must be constantly innovative to be competitive. Knowledge creation is among the most important enablers of innovation within modern organizations...........

Textile industry is considered as one of the polluting and chemically severe industrial sectors which utilizes large quantity of water and chemicals for its various wet processing operations. The effluent consists of chemicals like acids, alkalis, colors, high BOD/COD concentration, surfactants, dispersing agents, soap and metals. Most of the textile wastewater are extremely colored as they are normally discharged with a dye and many dyes are visible in water at concentrations as low as 1 mg/L. There are many alternative treatments, have been considered in laboratory also in full scale, including physical, chemical, biological, Advanced Oxidation Process (AOP) and a combination of them. This paper aims to put together different AOPs such as UV/H2O2, UV/TiO2 available for color and COD removal from dye solution. From the study it is concluded that AOPs can be effectively used as pretreatment process with a maximum COD removal of 95% and color removal of 64% by using UV/H2O2 Process.

In this paper, we obtain the ordinary generating function of the signless Lah numbers L(n, k) having only real zeros, and further derive the asymptotic normality of L(n, k). At the same time, we also prove the total positivity of the signless Lah triangle and the strict total positivity of the signless Lah square. 2010 MSC: 05A15; 05A16; 11B75
