This paper presents a study in which the main objective was to investigate the combined effect of noise and vibration on the performance of a readability task in a mobile driving environment. Subjects performed a readability task on a laptop computer in a sitting posture with their backs supported with a backrest under varying levels of noise and vibration. The data in terms of the mean number of characters read per minute were collected and statistically analyzed. Results showed that the individual effect of noise, vibration, and the operators’ gender as well as the interaction between gender and noise, and gender and vibration were statistically significant. However, the combined effect of noise and vibration was not found to be statistically significant. Results also indicated that gender was statistically significant at all levels of noise as well as vibration, and noise and vibration were statistically significant at both levels of gender. 相似文献

This paper aimed at to explore the consequences of cyclone victims due to unavailability of infrastructural supports and to
prop up the recognition that the infrastructure has a vital role to play in societies’ resilience during catastrophic situation.
The paper begins with a review of the science regarding climate change impact and cyclone disaster in Bangladesh. It emphasizes
the consequences of cyclone Aila in a selected coastal community in the remote coastal area. A field survey was conducted
by authors during March-August 2009. Eight available infrastructures were selected for this analysis. Uniformity of distribution
(R), demand index (Di) and degree of demand (DD) of the selected infrastructures were calculated by using nearest neighbourhood
methods of analysis. Results show that based on its specific planning standards none of the selected infrastructure can support
50% of the total population. Accordingly, it was observed that 76% respondent could not reach in safer place due to rush of
water intrusion and also because of the inundation of road-network. The nearness to the available cyclone shelter, and place
of taking shelter during cyclone is positively correlated (r = 0.38; p < 0.001). However, the poor people had less opportunity to take shelter in cyclone shelters, although none of the respondents
groups whose monthly income is above 75 USD stands without any infrastructural support. Such important observation may hint
the influence of local elites on the local disaster mitigation planning practice in Bangladesh. Almost 90% of the respondents
claimed that they had no access to enter the available cyclone shelter. Furthermore, the damaged infrastructures added more
hindrances during post disaster activities and also increased the sufferings of the victims. If there were adequate cyclone
shelters or rehabilitation centre, the affected people could take shelter and continue other works temporarily. Results drawn
from this research will be useful for local and national level planners, as well as international donors for future disaster
mitigation planning in the studied area and the methodology can be applied in similar countries and geographical territories. 相似文献

The plants of Spinacia oleracea L. grown on contaminated soil (CS) and different amendments of tannery sludge (TS) have shown high accumulation of metals in its edible part. The accumulation of toxic metal (Cr) in the leaves of the plants grown on CS was recorded as 40.67 microgg(-1)dw. However, the leaves of the plants grown on 100% TS have accumulated about two times (70.80 microgg(-1)dw) higher Cr than the 10% TS (31.21 microgg(-1)dw). Among growth parameters, the root length was more affected at 90 d than the shoot length, number of leaves and leaf area. The study of scanning electron micrographs showed 29.31% increase in stomatal length in the leaves of the plants grown on CS as compared to garden soil (GS), which served as control, however it decreased in the plants grown on higher amendments of TS. The decrease in MDA content at initial period of exposure and lower amendment was recorded in the leaves, whereas, significant increase (>10% TS onward) was observed with increase in tannery sludge ratio at 90 d as compared to GS. A coordinated increase in all the studied antioxidants (cysteine, non-protein thiol, ascorbic acid, carotenoid contents) was found up to 75 d of growth. At 90 d, most of the antioxidant decreased as compared to 75 d causing oxidative stress as evidenced by increased level of lipid peroxidation and decreased chlorophyll and protein contents. Maximum increase of 181.43% in MDA content and maximum decrease of 53.69% in total chlorophyll content was recorded in the leaves of the plants grown on 100% TS after 90 d of growth. The plants grown on CS have shown an increase in shoot length, number of leaves, leaf area, photosynthetic pigments and protein contents and in all the studied antioxidants. Thus, these plants are able to combat stress involving defense mechanism, resulting in healthy growth of the plants. The results are well coordinated as there is no change in the MDA content as compared to the plants grown on GS. In view of high Cr accumulation in edible part of S. oleracea grown on CS after irrigation with tap water, it is not advisable to use these plants for edible purposes. Summing up, it is recommended that the level of metals in the edible part should be checked instead of healthy growth as deciding parameter for consumption. It is demonstrated through this study that metal enriched plants have detoxification mechanism and grow well on organic matter enriched contaminated soil. 相似文献

Cyclone shelters and their locational suitability: an empirical analysis from coastal Bangladesh 总被引:1,自引:0,他引:1
Bishawjit Mallick 《Disasters》2014,38(3):654-671
Bangladesh is one of the poorest and the most disaster‐prone countries in Asia; it is important, therefore, to know how its disaster reduction strategies are organised and planned. Cyclone shelters comprise a widely acceptable form of infrastructural support for disaster management in Bangladesh. This paper attempts to analyse empirically their use during cyclones in a sample study area along the southwest coastal belt of the country. It shows how the location of a cyclone shelter can determine the social power structure in coastal Bangladesh. The results reveal that the establishment of cyclone shelters in the studied communities is determined by neither a right‐based nor a demand‐based planning approach; rather, their creation is dependent on the socio‐political affluence of local‐level decision‐makers. The paper goes on to demonstrate that socially vulnerable households (defined, for example, by income or housing conditions) are afforded disproportionately less access to cyclone shelters as compared to less socially vulnerable households. 相似文献

This study provides preliminary evidence that NO production could be a general attribute of algae. Anabaena doliolum was found to be a better NO producer than Scenedesmus and Synechoccocus. Experiments conducted with inhibitors of photosynthesis (DCMU), ATP synthesis (DCCD), and the uncoupler (2,4-DNP) and its analog arsenate clearly revealed that inhibition of nitrite assimilation through the blockage of nitrite reductase (NiR) is primarily responsible for NO emission. A linear relationship between nitrite concentration in the culture medium and NO in the exhaust gas supports the view that accumulation of nitrite is responsible for NO formation. A failure of Scenedesmus, grown in the medium substituted with W for Mo, to produce either NO/NO-2 in light or a 'light-off' peak, and a resumption of these activities upon the addition of Mo proved beyond doubt that a functional nitrate reductase (NR) is necessary for the production of nitrite and NO by algae grown on nitrate as the nitrogen source. Moreover, the appearance of a NO peak immediately after nitrite supplementation under dark conditions in W-substituted cultures with or without glucose ruled out an enzymatic role of NR in NO emission. 相似文献
