Review of Aakash Singh Rathore, Plato’s Labyrinth: Sophistries, lies and conspiracies in Socratic dialogues
No full textAakash Rathore Singh’s book Plato’s Labyrinth: Sophistries, Lies and Conspiracies in Socratic Dialogues attempts to break ground substantially, as far as I can discern, in two areas—one, on textual interpretive method or hermeneutics and the other on the content of what Plato has to say regarding issues like tyranny, the polis and the role of the philosopher in the political community. The kind of division I have just made regarding the intent of the author might not sit very well with the author himself, however. The reason I say this is because what Aakash Singh Rathore is attempting to do is to say that, with Plato, the content and the method of explicating that content always go hand in hand and that it is futile to separate them
A Global Analysis on Microgrids through the PESTEL Framework
No full textMicrogrids enable distribution of electricity with higher shares of variable renewables, higher power quality, greater reliability and higher efficiency. There are a large number of factors in addition to the technology, which affect their shift towards market competitiveness and widespread adoption. The PESTEL framework, covering Political, Economic, Social, Technical, Environmental and Legislative factors, is used to identify and describe the drivers and barriers for microgrid development at the global level. The framework enables a broader approach to describe potential for microgrid applications. The results aim to provide engineers, project developers and microgrid specialists with an overview of the prospects for microgrid deployment.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Energy Technolog
Effect of Insecticides (Pyrethroids) on Eosinophil Count in School Children
No full textBackground: Study was conducted in school children to reveal the toxic effects of pyrethroids which causes allergic reactions with in the body especially altered lung function tests and eosinophil count. Objective: In the present study, the effects of pyrethroids on eosinophil count of school children were analyzed.Methodology: The present study is a cross-sectional analytical study. The study was conducted at Government Girls Primary School, Sita Nagar, Karachi including 50 children with ages between 6 – 10 years. They were divided equally into two groups: group A (exposed to insecticidal spray) and group B (exposed to mosquito coil). The correlations between the insecticides (Pyrethroids), and eosinophil by linear regression analysis confirmed that insecticides (Pyrethroids) had a strong correlation with the eosinophil count under study exemplified by the significant increase in Eosinophil count was observed after exposure to mosquito coil whereas there was no association between insecticidal spray and Eosinophil count. Results: There was significant increase in Eosinophil count after exposure to mosquito coil whereas no association was observed between insecticidal spray and Eosinophil count.Conclusions: The use of spray over the coil is less hazardous to the health

Error Analysis of TRMM, WFD and APHRODITE datasets using Triple Collocation
No full textThe use of global precipitation datasets such as TRMM, WFD etc. for data scarce regions is gaining popularity since they provide forcing input for hydrological models. They make up for the lack of ground based data or the poor quality of whatever is available in many parts of the world. Using these datasets would be perfect if they were free of errors. Unfortunately, this is not the case. The geo-spatial data obtained from satellites or reanalysis products are not direct measures of precipitation. They are derived from atmospheric parameters such as cloud depth, brightness temperature etc. (Huffman 2007). The conversion of these to precipitation is done using complex algorithms. Efforts are made to calibrate this data but still errors sneak in. Similarly the interpolated gauge data like APHRODITE also has errors because of the inability of interpolation techniques to capture the high spatio-temporal variability in Precipitation. Hence the error estimation of these datasets remains a big problem. Lack of ground based data ensures there is no reference to check these global datasets against. In this research, Triple collocation technique is applied to 3 datasets namely APHRODITE, TRMM and WFD for the river basins in Myanmar. The technique gives an estimate of the residual errors in the 3 datasets (with uncorrelated errors) without using any ground measurements or true values (R. A. Roebeling 2012). This is the first time tit has been used to estimate errors in Precipitation datasets on a daily scale. Though the errors are not absolute, the results give an insight into the relative quality of these datasets. The errors have been calculated in space and time. Hence both temporal and spatial error characteristics are analysed. The study period is from 1998-2001. The results obtained show that for TRMM and WFD, the errors are concentrated and of higher magnitude. For APHRODITE, the errors are more evenly distributed in space. All three datasets showed high errors in the central dry parts and the delta region. Overall, APHRODITE seems to show lowest error values in space. The temporal error characteristics were also different for the 3 datasets. WFD showed highest average and maximum errors. TRMM had some very high error peaks but was in general better than WFD. Looking at the maximum and Average errors, APHRODITE seems to be the best of the three. WFD also shows some error peaks at the onset and end of Monsoon season. This shows its inability to estimate the localized pre and post monsoon storms. The assumption of uncorrelated errors was also verified post analysis. Errors for 2 locations, Bago and Yangon were used to make scatter plots. No strong correlation is visible in the scatter plots reinforcing the assumption that the errors are uncorrelated. The research shows that it is possible to make qualitative and quantitative inferences about the errors in the global precipitation datasets in the absence of in-situ measurements. Based on this research, it is concluded that overall, APHRODITE is the best of the 3 datasets. The possibility of a merged dataset formed by combining these 3 based on the error patterns observed in this study should be explored further.Water ResourcesWater ManagementCivil Engineering and Geoscience
A mild and selective method for the conversion of nitroalkanes to carbonyl compounds
No full textNef reaction is one of the most commonly used method for the conversion of nitroalkanes to carbnyl coacpunds. It was found that the salt of primary nitroparaffins are transformed in to aldehydes and those of secondary nitro coapounda into ketones, when they are treated with aqueous acid. Ernate procedures for effecting this transformation have been reported. Cedures appeared in the literature after the work of Sehecter and Williams using potassium penaanganate as the axidant. Recently, Kornblum and Steliou reported useful modif icationa of the original permanganate proeedtlre.
