BIOSORPTION OF HEAVY METAL CHROMIUM BY LIVE AND DEAD FUNGI ISOLATED FROM LEATHER TANNERY
Get PDFHexavalent chromium Cr (VI) is one of the most common environmental metal containment released primarily from industries such as leather tanning, metal plating, alloying, wood preservation and electroplating. Chromium (VI) is known to be highly toxic, mutagenic & carcinogenic to living organisms including mammals. Biosorption is potentially cost effective way to remove toxic heavy metals from industrial waste waters. The present study was planned to evaluate the heavy metals uptake potential of newly isolated white rot fungi from metals contaminated leather tannery sites. Two white rot fungi viz., Aspergillus niger, Rhizopus stolinifer were selected for biosorption of Cr(VI) study. Chromium resistance was tested at different concentration.. Biosorption efficiency was estimated by live and dead fungal mass. Dead immobilized white rot fungi had the effect of biosorbents dose on metal biosorption. The cost effective potential biosorbent can be developed by these two fungal species for removing chromium from industrial effluents as well. Key words: Biosorption, Chromium (VI), Aspergillus niger, Rhizopus stolinifer, Diphenyl carbazid

A STUDY ON EMPLOYEES JOB SATISFACTION SAKTHI SUGAR LIMITED COIMBATORE-A STUDY
Get PDFJob satisfaction is the positiveness or favorableness with which employees view their work. It expresses the amount of agreement between once expectations of the job and rewards that the job provides to him. Job satisfaction is a part of life satisfaction. Since a job is an important part of life, job satisfaction influences once general life satisfaction. The result is that satisfaction arises from a complex set of circumstances in the same way that motivation does job satisfaction is dynamic one. These has great relevance to the society and the management, when a worker is fully satisfied the mental pressure becomes less and he will be contributing to the organization and the nation. It also leads to a pleasant relationship with the family members. KEY WORD:Job Satisfaction, Motivation, Management, Rewards, Organisation EMPLOYEES JOB SATISFACTIO
CONTEXT-BASED SPECTRUM SHARING IN 5G WIRELESS NETWORKS
Get PDFDynamic range sharing can give numerous advantages to remote organizations administrators. Nonetheless, its effectiveness requires complex control components. The more setting data is utilized by it, the better of organizations is normal. An office for gathering this data, handling it, and controlling base stations oversaw by different organization administrators is a supposed Radio Environment Map (REM) subsystem. REM-based plans for the designation of base stations power levels in 4G/5G organizations, while considering impedance produced to an authorized organization. It is expected that the two organizations have various profiles of served clients, e.g., territory of their positions and development, which opens open doors for range sharing. The proposed plans have been assessed by methods for broad framework level reproductions and contrasted and two generally embraced strategy based range sharing reference plans. Reenactment results show that dynamic plans using rich setting data beats static, arrangement based range sharing plans
COLOR CRYPTOGRAPHY USING SUBSTITUTION METHOD
Get PDFThe dangers to data security are expanding at quickly. The best and general way to deal with counter such dangers is encryption. In Traditional encryption procedures replacement and rendering is utilized. In Substitution procedures plaintext is planned into figure text. In all conventional replacement methods plaintext characters, numbers and extraordinary images are subbed with another characters, numbers and uncommon images. In this new strategy an imaginative cryptographic replacement is proposed to produce a more grounded figure than the current replacement calculations. This technique centre around the replacement of characters, numbers and extraordinary images with shading blocks. This calculation of replacement depends on Play Color Cipher. This is an even framework which is executed by encryption of text by changing over it into colors. Each character of the plaintext is scrambled into a square of shading. Each character will be subbed by an alternate shading block. A tale strong content encryption strategy by utilizing Armstrong number, shading code, prime number and ASCII codes by utilizing replacement and stage procedure. In this encryption procedure 512-cycle size key is utilized for encryption. In replacement strategy message is changes into ASCII codes .In the proposed procedure irregular Armstrong number, prime number, shading code are created and key is scrambled by base-64 encoding for greater security. In the change cycle increase, expansion is performed on the information for encryption. The proposed approach deals with the symmetric encryption. The proposed method is then contrasted and the standard IDEA calculation. Result shows that the proposed method is hearty, quick and secur
DYNAMIC TEXT BLOCKING IN SOCIAL NETWORKS FOR USER EXPERIENCE
Get PDFOnline social systems have become an important part of everyday life. While initial examples were used to share personal content with friends more and more online social systems are also used to do business unfortunately, privacy concerns raised in the recommendation process impede the expansion of OSN users’ friend circle.
