Biosorption is a promising alternative method to treat industrial effluents, mainly because of its low cost and high metal binding capacity. In this work, Zinc and Chromium biosorption process by Sargassum sp. seaweed biomass was studied. The work considered the determination parameters of Zinc and Chromium sorption such as pH, temperature, agitation speed and biomass size. The optimum conditions were: pH3, temperature (303k) room temperature, biomass size 0.5mm and agitation speed 150rpm. The maximum uptake of Chromium and Zinc is 65% and 53% respectively. The kinetic study revealed that the adsorption of Chromium and zinc by Sargassum sp. fitted the Langmuir isotherm.Keywords

Breast cancer is the most common malignancy in women. Ring finger protein 110 was involved in the development of oncogenes, which mediate protein-protein interactions and involved in the formation of multi protein complexes. The investigation of this study reveals the modeling of the 3D structure of the protein with the final refinement of -700.41KJ/Mol. Casuarinin, a hydrolysable tannin isolated from the bark of Terminalia arjuna was investigated for its antiproliferative activity in human breast Adenocarcinoma. The energy value -40.87 Kcal/ mol and the Rms score value -1.00 showed the hydrolysable tannin (Casuarinin) has higher specificity and efficiency towards the target protein ring finger 110.Keywords

Water plays a very important role in supporting all forms of life. However if it contaminated, it has a great potential for transmitting a variety of diseases and illnesses. Waste water can serve as a source of infectious bacteria, viruses and other pathogens. The transmission of these diseases through waste water is a constant public threat. The purpose of this study was to identify the unknown bacteria, which cause dreadful disease to humans. The sample was collected from household waste water and the organism was screened using selective media and the taxonomy status was identified based on biochemical test. The molecular characterization is done by isolating DNA from the selected organism. Universal primer was designed based on 16srRNA. The conserved region was amplified and the amplified product was sequenced based on 16s rRNA.Keywords

In this present study, the silver nanoparticles synthesized biologically from the medicinal plant Pithecellobium dulce were tested for its antimicrobial activity against E.coli, S.aureus, P.aeuruginosa, and C.albicans. The biologically synthesized nanoparticles exhibited satisfactory inhibitions against all tested microorganisms when used at different concentrations viz. 1 mM, 3 mM and 5 mM; 3 mM (20 mg/500 μl distilled water) offered the highest sensitivity. Such green-synthesized antibacterial agents locally destroy bacteria, without being toxic to the surrounding tissue.Keywords

Objective: To introduce a cost effective and eco-friendly technique of preparing silver nanoparticles (Ag NP) from the medicinal plant, Pithecellobium dulce.
Methods: Ag NP of different concentration was prepared and characterized by using UV-Vis Spectrophotometer, Transmission Electron Microscopy (TEM), Scanning Electron Microscopy, X-Ray Diffraction (XRD), and Fourier Transform Infra Red (FTIR).
Results: Studies by UV-Vis spectroscopy showed absorption spectra of silver nanoparticles at an absorbance peak at 475nm, in all the three different concentrations (1mM, 3mM and 5mM). The size of Ag NP ranged 50-70nm and appeared to be dominantly spherical (and occasionally triangular). The XRD pattern revealed that these silver nanoparticles have a crystalline nature.
Conclusion: These nanoparticles produced by green synthesis proved stable in solution and can have promising role in nano-medicine.

Background/Objectives: To analyze and monitoring the activity of nodes using an IDS Intrusion Detection System which provide security to the system. Findings: In this research, a network building was made with simple node formation with a fitting technique. So that it is easy for a user or beginner to understand the asymptotic dominion factors, due to the wide growth of nodes on network. Intrusion detection system is made of several nodes. These nodes are grouped and combined as a network. Since each node in a network has unique characteristics they may have high chance of attack from malware during the communication between systems. Applications/Improvements: Network of topology is done by creating and connecting various sub networks. Sub networks traffic is cleared and monitored with the package of IDS. It works on synchronous message transfer mode which provides acknowledgement to sender and receiver. All sub networks is managed by its corresponding system and further provide update to the master node on the network. Due to this broadcast of messages all other nodes may be in safe state of avoidance from attacker.Keywords
