MICROBIAL METABOLISM OF POLYCYCLIC AROMATIC HYDROCARBONS (PAHs) : A Review[ ]


Polycyclic aromatic hydrocarbons (PAHs) are the class of hydrocarbons containing two or more fused aromatic hydrocarbons. They can persist in the environment due to their low water solubility. Polycyclic aromatic hydrocarbons are relatively abundant in the environment and toxic to mammals and aquatic organisms as they can be carcinogenic or mutagenic. PAHs have accumulated in the environment mainly as a result of anthropogenic activities such as the combustion of fossil fuels. Interest has surrounded the occurrence and distribution of PAHs due to their potentially harmful effects to human health. Some microorganisms were found to be capable of transforming and degrading PAHs and these abilities may be useful in removing them from the environment. This paper discusses the main micro-organisms involved in these transformations, the major aerobic and anaerobic breakdown pathways and the factors affecting microbial metabolism of polycyclic aromatic hydrocarbons.

ESTIMATION OF ASPECT ORIENTED PROGRAMMING USING DIFFERENT METRICES[ ]


Amongst all the approaches which are available of interconnectivity between the software modules, which approach or structure is clearly defined in ways of some object oriented metrics.we have collected few software metrics to analyze the software quality under structural analysis. Aspect Oriented programming generates the software modules under new perspective called aspects. Aspect basically defines the function or the event of the software system that itself collect number of attributes and functions incorporated to the individual entity. The structural analysis mechanism is performed to analyze individual component of the software system. Once the individual module analysis is performed, at second stage, the module interaction analysis takes place. In the final stage, the collaborative analysis of all these modules takes place to perform the system integration analysis. In this section, analysis of complete software quality takes place.

ENABLING VIRTUAL PRIVATE NETWORK FOR E-MAIL COMMUNICATION[ ]


There is an increasing demand nowadays to connect to internal networks from distant locations. Employees often need to connect to internal private networks over the Internet (which is by nature insecure) from home, hotels, airports or from other external networks. Security becomes a major consideration when staff or business partners have constant access to internal networks from insecure external locations.VPN (Virtual Private Network) technology provides a way of protecting information being transmitted over the Internet, by allowing users to establish a virtual private “tunnel” to securely enter an internal network, accessing resources, data and communications via an insecure network such as the Internet.

Mystic features in works of Fayyaz[ ]


Hakim Molla Abdolrazzagh- Ibn-e-Ali Lahiji, Fayyaz-e-Lahiji, was among prominent Shiat philosophers and orators. He learned philosophy in classes of a famous philosopher called Molla Sadra and he was one of his best students. Always outstanding philosophers and orators have had their own line of thought and they held independence in thought. Although Hakim Lahiji was a student for Mirdamad and Sadrolmotaalehin, he had never followed them blindly and he had certain thoughts and viewpoints in philosophical and belief issues. In all works by Hakim Lahiji, his deep awareness of thoughts and beliefs of great philosophers, orators, followers of different religions, and different branches of Islamic thought such as Ashaereh, Mofawwazeh, Kisanieyeh, … can be observed clearly. In this research we have tried to study about thought philosophy of Fayyaz-e-Lahiji and his attitudes towards mysticism which has been one of the common beliefs held by scientists and scholars in Safavid period.

Determination of field intensities belonging to the wedge regions adjacent to a convex triangular obstacle subject to axially independent conditions[ ]


The present paper gives an interaction of standing electromagnetic waves with a smooth convex triangular obstacle K and its adjacent wedge regions. The concerning electromagnetic fields are supposed to be independent of the variations along the axis of K. Governing Helmholtz wave equation, being resulted from the Maxwell’s field equations, have been encountered subject to initial boundary conditions of the field intensities on the wedge surfaces . The concerning boundary value problem has been particularly associated with Dirichlet and Neumann conditions on , giving rise to Dual-Bessel series relations. The unknown coefficients of the said dual series relations have been determined by making use of Lommel’s integral for a pair of Bessel functions of the first kind. Two existence theorems regarding the cylindrical mode of polarisation of electromagnetic wave have established, furnishing thereby the components electric and magnetic field intensity vectors. Wave characteristics like reflection and transmission have been determined on the basis of said existence theorem. Finally the expressions of the field intensities H and E have been utilized for determining the current density.
