Abstract

Oxidative stress plays a significant role in pathogenesis of chronic renal failure (CRF). Redox imbalance caused by increased ROS production and/ or reduced antioxidant reserve, leading to pathological consequences including damage to proteins, lipids and DNA. The present paper focuses on the extent of free radical damage on lipid (measured as malondialdehyde, MDA) and effect on antioxidant defense mechanism (measured as vitamin C) in the serum of CRF patients predialytically.40 cases and 40 controls between age group of 25 - 60 were taken. The level of MDA, creatinine, blood urea nitrogen was significantly increased, antioxidant vitamin levels were decreased in CRF patients as compared to normal subjects.The elevated MDA level can lead to lipid peroxidation and can also promote the complication of CRF. The antioxidant levels were decreased , so these patients can be supplemented with antioxidant vitamins for preventing lipid peroxidation and occurance of complication.

Abstract

This paper is a general survey of all the security issues existing in the Internet of Things (IoT) along with an analysis of the privacy issues that an end-user may face as a consequence of the spread of IoT. The majority of the survey is focused on the security loopholes arising out of the information exchange technologies used in Internet of Things. No countermeasure to the security drawbacks has been analyzed in the paper.

Abstract

This paper analyzes the various authentication systems implemented for enhanced security and private reposition of an individual's login credentials. The first part of the paper describes the multi-factor authentication (MFA) systems, which, though not applicable to the field of Internet of Things, provides great security to a user's credentials. MFA is followed by a brief description of the working mechanism of interaction of third party clients with private resources over the OAuth protocol framework and a study of the delegation based authentication system in IP-based IoT.

Keywords

Abstract

This paper is a comprehensive survey of the various operating systems available for the Internet of Things environment. At first the paper introduces the various aspects of the operating systems designed for the IoT environment where resource constraint poses a huge problem for the operation of the general OS designed for the various computing devices. The latter part of the paper describes the various OS available for the resource constraint IoT environment along with the various platforms each OS supports, the software development kits available for the development of applications in the respective OS'es along with the various protocols implemented in these OS'es for the purpose of communication and networking.

Keywords
