there is no single standard technique or methodology to characterize the size, structure, number, and chemical composition of airborne carbon nanotubes. existing analytical instruments and analytical techniques for evaluating nanoparticle concentrations cannot simultaneously provide morphology, state of agglomeration, surface area, mass, size distribution and chemical composition data critical...
An analysis of the Global Youth Tobacco Survey for Kilimanjaro, Tanzania was carried out to assess sex differences in the prevalence rates and predictors of current cigarette smoking among in-school adolescents. A total of 2323 adolescents participated in the study of whom 53% were females and 47% males. The prevalence of current cigarette smoking was 3.0% and 1.4% among males and females, resp...
In the Transmission of Videos over channel, Video frames are corrupted by salt and pepper noise (Impulse Noise), due to faulty communication systems. The objective of this paper is to implement a better filtering technique that makes the noisy video frames to noise free video frames. Median filters are the best known non-linear digital filters based on order statistics to solve the present prob...
Stringent regulations worldwide will limit the level ofparticulate matter (PM) emitted from gasoline engines equipped with direct fuel injection. Gasoline particulate filters (GPFs) present one strategy for meeting PM limits over the full operating range of the engine. Over time these filters accumulate incombustible ash, increasing system pressure drop and adversely effecting engine performanc...
OBJECTIVE To assess the risk of lung cancer in smokers of medium tar filter cigarettes compared with smokers of low tar and very low tar filter cigarettes. DESIGN Analysis of the association between the tar rating of the brand of cigarette smoked in 1982 and mortality from lung cancer over the next six years. Multivariate proportional hazards analyses used to assess hazard ratios, with adjust...
The Quality of Service (QoS) requirements such as delay and cell loss ratio (CLR) are very stringent for video transmission. These constraints are difficult to meet if high network utilization is desired. Dynamic bandwidth allocation in which video traffic prediction can play an important role is thus needed. In this paper, we suggest to predict the variation of I frames instead of the actual s...
Playfield is one of main parts appearing in typical scenes of sports videos. The segmentation of playfield is essential because it usually offers important cue of higherlevel content in sport videos. The colors in playfield may change significantly due to variation of illumination, which thus results in a large amount of segmentation errors for color-based segmentation schemes. In this paper, w...
Cigarettes have a bad impact on health, one of which is the most fundamental to blood, that hematocrit. The goal research were comparing and correlating cigarettes with hematocrit,used cross sectional design in Mulyasari Subang Village, West Java, 55 male respondents. Respondents who smoked 27 people. Smoking duration 15.93 years ± 7.54. type filters, 55.6%. hematocrit value 61.8% low category,...
In power plant, coal ash obtained by combustion is mixed with river water and transported to the dump. Sequential extraction was used in order to assess pollution caused by leaching of elements during ash transport through the pipeline and in the storage (cassettes). A total of 80 samples of filter ash as well as the ash from active (currently filled) and passive (previously filled) cassettes w...
