A novel approach towards evaluation of primary metabolite and antimicrobial screening in Butea monosperma (Lamarck. ) Kuntze.
The quantification of primary metabolites and antimicrobial activities of medicinal plant Butea monosperma (Lam.) kuntze against clinical isolates was evaluated. The present study was aimed to determine the antibacterial and antifungal activities of the chloroform and ethanolic extract of leaf, flower, root and seed of the Butea monosperma (Lam.) kuntze. Antimicrobial activity was determined by using agar well diffusion method. Ethanolic extracts of leaves and flowers possessed highest antibacterial activity against E.coli and highest antifungal activity against Trichoderma ressi and Fusarium oxysporum. Chloroform extracts of seeds have the highest antibacterial activity against Bacillus subtilis and highest antifungal activity was observed in chloroform extracts against Fusarium oxysporum . The present results showed potential of this medicinal plant which can be used as herbal drug as therapeutic ventures in future aspects.

Absorptive Capacity and Innovative Behavior among Engineers in Malaysia
The objective of this paper is to investigate the relationship between individual’s absorptive capacity and innovative behavior among engineers in the electrical and electronic (E&E) sector in Malaysia. The study utilized survey method to collect the data. There were 305 responses for the survey. Partial least square (PLS) properties of structural equation modeling (SEM) were used to measure the relationships between the variables. The study found only partial support in absorptive capacity ability to influence innovative behavior.

Adsorption of acenaphthene unto activated carbon produced from agricultural wastes
The suitability and the performance of activated carbon produced from flamboyant pod back, milk bush kernel shell and rice husk for the effective removal of acenaphthene from simulated wastewater under the influence of carbonization temperature and initial concentration were investigated. The adsorption capacities of all the activated carbons obtained from the selected raw materials are influenced by increasing carbonization temperature. Activated carbons obtained from rice husk at carbonisation temperature of 600 0C had the maximum adsorption capacity (5.554 mg/g) while carbons produced from milk bush at carbonisation temperature of 300 0C had the minimum adsorption capacity (1.386 mg/g), for the adsorption of acenaphthene from the simulated wastewater. The removal efficiencies of the investigated adsorbents generally rank high and the highest value (80.56 %) was obtained for the adsorption of acenaphthene by rice husk carbonized at 600 0C. Furthermore, the removal efficiencies obtained in the study decreased as the initial concentrations of the adsorbate increased. The four selected isotherm models; Freundlich, Langmuir, Temkin and Dubinin-Radushkevich described well the equilibrium adsorption of acenaphthene unto activated carbon derived from Flamboyant pod bark, milk bush kernel shell and rice husk. Sequence of suitability of the selected isotherms in the study was Temkin ? Freundlich > Dubinin-Radushkevich > Langmuir for adsorption of acenaphthene. It therefore shows that Temkin isotherm is the most suitable model for fitting experimental data obtained from adsorption of acenaphthene from simulated wastewater unto activated carbon produced from Flamboyant pod bark, milk bush kernel shell and rice husk.

An n-dimensional pseudo-differential type operator involving Hankel type transformation
In this paper Bessel type differential operator and an n-dimensional pseudo-differential type operator involving the n-dimensional Hankel type transformation is defined. The symbol class is introduced. It is shown that pseudo-differential type operators associated with symbols belonging to this class are continuous linear mappings of the n-dimensional Zemanian space into itself. An integral representation for the pseudo-differential operator is obtained. By using the Hankel type convolution, it is shown that the pseudo-differential type operator satisfies a certain norm inequality.

An Security Aware Routing Protocol for Mobile Ad Hoc Networks
Mobile Ad-Hoc Networks (MANETs) uses security routing scheme for establishing secure route and securely data transmission. The security issues in MANET are mostly concentrated in two parts. The main security threat in MANET is integrity, non-repudiation and privacy. To combat with these security threats, many secure routing protocols has been designed to reduce the security threats in MANET. In this paper we have proposed Privacy Aware Routing Protocol (ESARP) to enhance the security levels in the routing protocol to prevent the network attacks. The proposed work consists of three parts. In the first part each node perform a key exchange operation with its one and two hop distance neighbours, in the second step, secure route establishment and in the third step, secure data communication is performed. Key exchange operation is done in two steps; in the first step, source node (S) exchanges public key (e) with its one hop distance nodes and establish a secret key (SK), and in the second step, source node exchanges public key with its two hop distance nodes and establish a secret key. On establishing the key exchange process node can participate in routing process. In route establishment process, secure route will be established between the sender and receiver. In the third step, sender and receiver will exchange their public key securely and establish a secret key for communication and then data communication is performed.

Analytical solution of Unsteady MHD free Convection and mass transfer past a Vertical Porous Plate with Slip Flow Region
The unsteady free convection flow of a laminar viscous, incompressible, electrically conducting with chemical reactive species and heat generation fluid past a semi-infinite vertical plate embedded in uniform porous medium with slip flow region has been studied. The governing equations are solved analytically using perturbation techniques. The influences of the various parameters on the flow field, Temperature field, Mass concentration field, Skin friction, Rate of heat transfer and Rate of mass transfer are extensively discussed through Graphs and Tables.

Analyzing blood cell images to differentiate WBC and counting of linear & non-linear overlapping RBC based on morphological features
In this paper we propose a new set of features based on morphology for total RBC count in given blood sample is explained along with classification of WBC. For the diagnosis of any disease first requirement is complete blood count i.e total number of RBC, WBC and platelets in given blood sample. And if there are excess of any of these types or any of these is few in number then this gives the doctor a basic idea that the person is not healthy for sure. To do this manually is very tedious. Here RBC and WBC are first differentiated and then counted through some algorithm. Implementation here is done through MATLAB.

Antimicrobial, DNA cleavage and antitumoral properties of some transition metal complexes of 1, 10 –phenanthroline and 2, 2? – bipyridine: a review
Transition metal ions coordinated to nitrogen containing ligands, such as 1, 10 – phenanthroline and/or 2, 2? – bipyridine have found wide applications in chemotherapy. The ligands form very stable chelates with many first row transition metals and the ligands, as well as some of their derived complexes, do exhibit antimicrobial properties. The mechanism of action of these novel set of drugs was reviewed and compared to that of the conventional antifungal drugs (polyene and azoles). Transition metal complexes of 1, 10 – phenanthroline and/or 2, 2? – bipyridine demonstrated a significantly different mode of action and thus could be used either in combination with existing antimicrobial drugs or in a situation where resistance to conventional antimicrobial drugs have emerged. However, the antimicrobial properties of the various transition metal complexes of phen and bpy are not uniform indicating a degree of metal – ion dependency on their mode of action. The DNA binding, DNA cleavage and antitumoral properties of the transition metal complexes of the chelating ligands were also reviewed. DNA cleavage by these metallonucleases is reported to be dependent on the presence of a biological reductant (e.g. L-ascorbic acid, gluthathione) and an oxidant ( H2O2). The metal complexes were reported to control cancer cell division by significantly reducing DNA synthesis. However there is a significant difference in the mode of action of these novel sets of antitumoral drugs compared to the conventional antifungal drug cisplatin.
