A Comparative Study of Fly Ash and Na-Fly Ash as Adsorbents for Removal of Cr (VI), Cu (Ii) and Fe (Ii) From Aqueous Solutions

Removal of Cr(VI), Cu(II) and Fe(II) from aqueous solutions has been studied using fly ash (FA) and Na-fly ash (Na-FA) as adsorbents. The process of adsorption has been established to be dependent on concentration of the metal ions, time of contact, dosage of adsorbent and on temperature. The adsorptive behaviour has been found to fit in Freundlich adsorption isotherm. Ion exchange and complexation at the surface are the major mechanisms involved in the removal of metal ions from aqueous solution. Na-fly ash is found to have better adsorption capacity than FA which is attributed to the increased content of Na ions on the surface which is readily available for exchange with metal ions. The observed results indicate that Na-FA has excellent adsorption capacity compared to FA and can be used as a potential cost-effective adsorbent for removal of heavy metal ions from industrial effluents.

Dowry Prohibition Act- A Shelter or A Weapon

Though system of dowry existed in India even before the British Rule, the format of this tradition was entirely different. It was a form of recourse for woman in case of emergency in which her father use to give a part of property to the bride to whom she was entitled but not to the groom in shape of land, gifts, etc. And the bride was sole beneficiary of this property. But now days, dowry means goods given by family of bride to the bridegroom, his parents and relatives on their marriage either on demand or without demand which may include cash, ornaments, furniture, utensils, house hold or immovable property. In India dowry is prohibited and who so ever demand for dowry is punishable under Section 498-A IPC.

Review on Recent Techniques for Reducing Packet Drops in Dense and Sparse Vehicular Network Scenarios

Vehicular networks have been the trending topic of research since the past decade that can be attributed to its enormous potential to enhance road safety, traffic efficiency and furnish un-interrupted service to the users over the course of mobility. Vehicular communications are being perceived as an enabler for driverless cars of the future. Automobile industries, governments and research community across the globe are investing extensive effort and capital towards the deployment of vehicular networks owing to the gigantic potential envisaged in its applications. Vehicular networks represent a special sub-class of MANET that presents numerous research challenges due to their distinct features such as hybrid network architectures, node movement characteristics and new application scenarios. Designing efficient routing protocols for VANET remains one of the most prominent challenging issues. The major challenge associated with Delay Tolerant Networks (DTN) protocols is ensuring less packet drops while ignoring delay. This paper reviews the works that lessen packet drops by exploiting position, social and velocity information of nodes in dense and sparse vehicular networks.

Study on the impact of family’s Socio Economic status on employee’s level of satisfaction with organizations

Socioeconomic status (SES) is an economic and sociological combined total measure of a person's work experience and of an individual's or family's economic and social position in relation to others, based on income, education, and occupation. When viewed through a social class lens, privilege, power, and control are emphasized. Low SES and its correlates, such as lower education, poverty, and poor health, ultimately affect the society as a whole. Additionally, Mortality differences within society are greater than indicated by social class based on occupation alone. Irrespective of social class, men with greater material assets have lower rates of mortality from all causes than men less well endowed, independent of a wide range of lifestyle and biological factors. These findings suggest that mortality differences within our society are closely related to relative wealth. Inequities in wealth distribution, resource distribution, and quality of life are increasing globally. Each employee may differ at least with any one of socio economic variables related to them. Hence the differing employee satisfaction with organization among different employees is analyzed from point of view of their socio-economic variable. In this study, the factors that influence the employee satisfaction with organization among the selected respondents has been studied in terms of social status of employees.

An Automated Storage Area

The fast growth of data intensive applications has caused a change in the traditional storage model. The server to disk approach is being replaced by storage area networks (SANS), which enable storage to be externalized from servers, thus allowing storage devices to be shared among multiple servers. The prominent technology for implementing SANs is iSCSI, due to its suitability for storage networking. The iSCSI SAN is a block-level shared-storage alternative to Fiber Channel that is becoming increasingly popular among SME organisations. One of the reasons iSCSI SANs are popular for smaller businesses that often have fewer staff members with technical expertise is because they are easy to set up and maintain compared to Fiber Channel SANs. A storage area network (SAN) is a secure high speed data transfer network that provides access to consolidated block level storage. SAN makes a network of storage devices accessible to multiple servers. SANs are sometimes also referred to SAN storage, SAN network, network SAN etc. In this paper, we proposed the automated system using this SAN technique with respect to iSCSI protocol as a storage solution by LVM sharing system and shell scripting and realized a SAN storage and encryption system, through this technology to achieve a static data encryption which realized a flexible security management strategy by multiple-key and multiple layer encryption system to project the physical resource through iSCSI’s protocol stack and virtualization techniques.
