Managing Context Based Access Control Systems for Mobile Devices

An android is a name given to a mobile operating system made by Google. An operating system is software that acts as an interface and manages computer hardware and software resources. In any other operating system, there is a problem of malevolent software or malicious contents trying to wreck havoc. A malicious software is any software that is used for or can disrupt computer operation and gather access to private systems [1].Android applications will frequently have access to private and confidential resources and information in the user's device. There is high degree of possible exploitation of these resources. We can take an example of an application using a video camera to document the on-going activities of an organization. Android users do have a certain amount of control over the application capacities and capabilities after installing it based on user's context [2]. In our paper, we propose another way where network managers can control what applications are granted access or revoked. DOI: 10.17762/ijritcc2321-8169.15036

EVALUATION OF STANDARDS OF SOME SELECTED COSMETIC PREPARATIONS

The aim of the present work is to analyze the standards of marketed cosmetic products which are largely consumed in day to day life of the people. The cosmeceutical should be tested for efficacy to ensure a proven skin benefit and also to substantiate marketing claims. The work was done by keeping the ideas of Bureau of Indian Standards to analyze the cosmetic products. The evaluation for the following cosmetics such as tooth pastes (Colgate, Closeup, Pepsodent, Vicco and Anchor) and face powders (Ponds, Eva, Fa, Cuticura and Spinz) are performed for their quality. All the marketed tooth pastes and face powders which had been evaluated complied with the standards specified by Bureau of Indian Standards. Hence all the selected marketed tooth pastes and selected face powders were found to be of good quality

Experimental investigations on mechanical properties of geopolymer concrete composites

Due to growing environmental concerns of the cement industry, alternative cement technologies have become an area of increasing interest. It is now believed that new binders are indispensable for enhanced environmental and durability performance. Geopolymer concrete (GPC) is an innovative method and is produced by complete elimination of ordinary Portland cement by fly ash. Geopolymer concrete has two limitations such as delay in setting time and necessity of heat curing to gain strength. Present research aimed to rectify these two limitations of GPC by replacing 10% of fly ash by OPC on mass basis. This paper presents the results of an experimental investigation on the mechanical properties of Geopolymer Concrete Composites (GPCC) containing 90% Fly ash (FA), 10% Ordinary Portland Cement (OPC) and alkaline liquids. The study analyses the impact of replacement of 10% of fly ash by OPC in the GPC mix on the mechanical properties such as density, Compressive Strength, Split Tensile strength and Flexural strength both in ambient curing at room temperature and heat curing at 60o C for 24 hours in hot air oven. Mixtures were prepared with alkaline liquid to fly ash ratio of 0.4. Based on the test results, empirical expressions were developed to predict split tensile strength and flexural strength of GPC as well as GPCC in terms of their compressive strength

Multimodal Evaluation of TMS - Induced Somatosensory Plasticity and Behavioral Recovery in Rats With Contusion Spinal Cord Injury

Introduction: Spinal cord injury (SCI) causes partial or complete damage to sensory and motor pathways and induces immediate changes in cortical function. Current rehabilitative strategies do not address this early alteration, therefore impacting the degree of neuroplasticity and subsequent recovery. The following study aims to test if a non-invasive brain stimulation technique such as repetitive transcranial magnetic stimulation (rTMS) is effective in promoting plasticity and rehabilitation, and can be used as an early intervention strategy in a rat model of SCI.Methods: A contusion SCI was induced at segment T9 in adult rats. An rTMS coil was positioned over the brain to deliver high frequency stimulation. Behavior, motor and sensory functions were tested in three groups: SCI rats that received high-frequency (20 Hz) rTMS within 10 min post-injury (acute-TMS; n = 7); SCI rats that received TMS starting 2 weeks post-injury (chronic-TMS; n = 5), and SCI rats that received sham TMS (no-TMS, n = 5). Locomotion was evaluated by the Basso, Beattie, and Bresnahan (BBB) and gridwalk tests. Motor evoked potentials (MEP) were recorded from the forepaw across all groups to measure integrity of motor pathways. Functional MRI (fMRI) responses to contralateral tactile hindlimb stimulation were measured in an 11.7T horizontal bore small-animal scanner.Results: The acute-TMS group demonstrated the fastest improvements in locomotor performance in both the BBB and gridwalk tests compared to chronic and no-TMS groups. MEP responses from forepaw showed significantly greater difference in the inter-peak latency between acute-TMS and no-TMS groups, suggesting increases in motor function. Finally, the acute-TMS group showed increased fMRI-evoked responses to hindlimb stimulation over the right and left hindlimb (LHL) primary somatosensory representations (S1), respectively; the chronic-TMS group showed moderate sensory responses in comparison, and the no-TMS group exhibited the lowest sensory responses to both hindlimbs.Conclusion: The results suggest that rTMS therapy beginning in the acute phase after SCI promotes neuroplasticity and is an effective rehabilitative approach in a rat model of SCI

Farmer’s participatory research thirty-four years of Operational Research Project on dryland agriculture(1984-2018)

Not AvailableOperational Research Project on Dryland Agriculture was initiated at Ananthapuramu under All India Coordinated Research Project for Dryland Agriculture under ICAR and Canadian International Development Agency (CIDA) to meet the dryland research needs on farmers’ participatory approach in Scarce Rainfall Zone of Andhra Pradesh and similar land topography rainfall and other natural resources in the country. The research experiences are documented as “Farmers’ Participatory Research-Three Decades of Operational Research Project onDrylandAgriculture (1984-2018)”. This book contains enormous analysis and feedback and research finding of ORP on DrylandAgriculture over three decades in different watersheds. We are sure that the book will be of immense use of extension scientists, students and agriculture and allied department staff working in DrylandAgriculture and watershed management. The authors express their profound gratitude to Dr.V.Damodara Naidu, Honb’le Vice Chancellor, Dr.N.V.Naidu, Director of Research, ANGRAU, Lam,Guntur and Dr.M.Subba Rao, Associate Director of Research, RARS, Nandyal for their encouragement, valuable guidance in bringing out this publication.
