Cloud Computing is an environment for providing information and resources that are delivered as a service to end-users over the Internet on demand. Thus cloud enables users to access their data from any geographical locations at any time and also has brought benefits in the form of online storage services. Cloud storage service avoids the cost expensive on software, personnel maintenance and provides better performance, less storage cost and scalability. But the maintenance of stored data in a secure manner is not an easy task in cloud environment and especially that stored data may not be completely trustworthy. Cloud delivers services through internet which increases their exposure to storage security vulnerabilities. However security is one of the major drawbacks that preventing several large organizations to enter into cloud computing environment. This work surveyed on several existing cloud storage frameworks, techniques and their advantages, drawbacks and also discusses the challenges that are required to implement secure cloud data storage. This survey results help to identify the future research areas and methods for improving the existing drawbacks.Keywords

Cloud Computing is continuously evolving and showing consistent growth in the field of computing. But, the security issues and threats associated with it still stay as a cumbersome. The focal point of this paper is Privacy preserving in cloud computing. This paper analyses and discusses various methods like adopting cryptographic methods, writing access rights and policies, anonymising data, segregating or fragmenting and then reconstructing the data, etc. All these approaches would preserve the privacy of user and data and while performing public auditing on the cloud data. The surveyed approaches are showcased and compared with one another, stating their pros and cons. Finally, the results are centralized and the issues to be concentrated in the future are drawn out. Enabling complete user control over his data, anonymising or encrypting the sensitive data before outsourcing, notifying the data owner upon data access, altogether with the tied up security mechanisms would nullify the privacy issue. This would serve as a helping note in the progress of strengthening the privacy preserving approaches in Cloud Computing.Keywords

Neurosteroids play a vital role in governing the physiology of reproduction next to neuropeptides and neurotransmitters. Gonadal development influences the steroid synthesis in Central Nervous System (CNS) and also the CNS regulates the gonadal steroid production. It is well known that the receptors of estrogen modulate the production of GnRH, and serotonin, dopamine and GABAergic neurons modulate the steroidogenic enzyme. However, the influence of neurosteroids, Estrogen (E2) and Testosterone (T), and its presence and synthetic pathway variations are not studied in detail in Tilapia. Hence, the present study of identifying various steroids present in the total and regions of Tilapia brain resulted in the quantitative difference in E2, T, 11-Ketotestosterone (11-KT), Androstenedione (A), DHEA, and 21-Hydroxyprogesterone (21-P). The reproductively active fishes of female brain shows the high quantity of testosterone when compare with the male brain. It has been derived that the Cyp19 and Cyp17 gene expressions are higher than the Cyp21 by which the pathway of progesteronal derivatives are not documented. The steroidal production in the incubated regions of Tilapia brain highlights the augmented presence of 5á-or 3á-reductase evidence the elimination pathway. The quantitative expression of mRNA analysis of 3á-HSD, 3â-HSD, Cyp17, Cyp19 and Cyp21 substantiate the variation in sex and maturation of gonadal stages. Aromatase indicate the shift in the sex dependent pathway. The sulphated steroids of pregnenalone and DHEA indicate the presence of Hydroxysteroid Sulfotransferase (HST) for purging action. The study suggests that the sexual modulation can be done at CNS through manipulating the steroidal receptors more particularly at thalamus region of brain.Keywords

In the past, man in his quest for better standard and quality of life has allowed all other consideration to take a back seat and this accelerated the process of environmental degradation and began to threaten the earth's delicate ecological balance through which life on this planet survives. All manufacturing activities necessarily generate some form of waste. The manufacturing process does not consist o f 100 percent of conversion o f material and energy inputs into usable final products; some portion of the material and energy inputs inevitably ends up as wastes. When the waste generated exceeds the maximum assimilative capacity of the environment it becomes pollution. This paper focuses on LEAN productions, which aims at elimination of wastes there by reducing the environmental degradation.
