This study reports the quantification of the toxicity of particulate matter (PM)-bound metals and their possible associated risks to human health. For assessment of PM, 24-h samples of PM(10) and PM2.5 were collected by Mini Vol-TAS sampler at an urban site of Pune. Samples were sequentially extracted with ultrapure water and concentrated HNO3 and analyzed(More)
In recent years researchers have applied the concept of Genetic Algorithm in generation of test data for effective software testing. Several attempts have been made to develop a system to generate test data automatically. The existing such systems do not guarantee to generate test data in only feasible paths. This paper proposes a method to generate(More)
In this paper, an algorithm for embedding copyright mark into host image based on discrete cosine transform (DCT) and Spread Spectrum has proposed. The proposed algorithm works by dividing the cover into blocks of equal sizes and then embeds the watermark in middle band of DCT coefficient of cover image. Performance evaluation of proposed algorithm has been(More)
Programmable reversible logic is emerging as a prospective logic design style for implementation in modern nanotechnology and quantum computing with minimal impact on circuit heat generation. Recent advances in reversible logic using and quantum computer algorithms allow for improved computer architecture and arithmetic logic unit designs. In this paper,(More)
Marine algal resources are of significant importance due to their renewable nature and plentiful availability; however, they also are subjected to indiscriminate harvesting. Despite multi-organizational efforts under the Bay of Bengal Program implemented by the Food and Agriculture Organization (FAO) of the United Nations, the Indian agar industry still(More)
This paper presents the distinctiveness of particulate matter (PM) mass concentrations (PM10, PM2.5, and PM10-2.5) and meteorological effect in Pune city during 2011-2012. The PM samples were collected using Mini-Vol TAS air sampler (Airmetrics Co. Inc., 5 l min(-1) flow rate). The meteorological parameters were also measured during the study period. The(More)
In the present study, metal-facilitated free radical generation in particulate matter (PM) and its association with deoxyribonucleic acid (DNA) damage were studied. The examined data showed that the concentration of fine PM in Pune exhibited seasonal variations. Inductively coupled plasma-atomic emission spectrometry (ICP-AES) was used to examine the metal(More)
The present study deals with the assessment of sequential extraction of particulate matter (PM)-bound metals and the potential health risks associated with them in a growing metropolitan city (Pune) of India. The average mass concentration of both PM2.5-10 and PM2.5 exceeded the National Ambient Air Quality Standards. Significant seasonal variation in mass(More)
