The TLC monitored reaction of 2,2'-dithiobisbenzothiazole with 2,3-dithiopropanol resulted in the formation of unsymmetrical disulfides i.e., 2,3-bis(2-benzothiazolyldisulfanyl)-1-propanol (3). The molecule is characterized using proton NMR study. The molecular model study of the compound 3 reveals the proximity of the -OH proton to the nitrogen atom of the benzothiazole ring providing the probable hydrogen bond formation which is further confirmed by the study of hydrogen-deuterium exchange reaction.

Most of the research in remote sensing is focused on developing a well-defined and reliable automated process for the extraction of information from different types of imagery. This paper deals with the extraction of linear anthropogenic objects (especially buildings) in hilly areas. The analysis of digital surface models from hilly terrain data is still challenging, especially for highly sloped landscapes. Commonly, the first task to study satellite data is to separate ground and object points as a preparatory step for further object classification. In this paper, object and ground separation in hilly terrain (PAN image of Indian Remote Sensing (IRS)-1C satellite) is addressed by employing wavelets. Then the extraction of desired objects (buildings) is done by employing the marker-controlled watershed segmentation. Experimental results demonstrate the method to be effective. © 2010 Taylor & Francis.

Renewable and Sustainable Energy Reviews | Year: 2010

The present rate of economic growth is unsustainable without saving of fossil energy like crude oil, natural gas or coal. Thus mankind has to rely on the alternate/renewable energy sources like biomass, hydropower, geothermal energy, wind energy, solar energy, nuclear energy, etc. On the other hand, suitable waste management strategy is another important aspect of sustainable development. The growth of welfare levels in modern society during the past decades has brought about a huge increase in the production of all kinds of commodities, which indirectly generate waste. Plastics have been one of the materials with the fastest growth because of their wide range of applications due to versatility and relatively low cost. Since the duration of life of plastic products is relatively small, there is a vast plastics waste stream that reaches each year to the final recipients creating a serious environmental problem. Again, because disposal of post consumer plastics is increasingly being constrained by legislation and escalating costs, there is considerable demand for alternatives to disposal or land filling. Advanced research in the field of green chemistry could yield biodegradable/green polymers but is too limited at this point of time to substitute the non-biodegradable plastics in different applications. Once standards are developed for degradable plastics they can be used to evaluate the specific formulations of materials which will find best application in this state as regards their performance and use characteristics. Among the alternatives available are source reduction, reuse, recycling, and recovery of the inherent energy value through waste-to-energy incineration and processed fuel applications. Production of liquid fuel would be a better alternative as the calorific value of the plastics is comparable to that of fuels, around 40 MJ/kg. Each of these options potentially reduces waste and conserves natural resources. Plastics recycling, continues to progress with a wide range of old and new technologies. Many research projects have been undertaken on chemical recycling of waste plastics to fuel and monomer. This is also reflected by a number of pilot, demonstration, and commercial plants processing various types of plastic wastes in Germany, Japan, USA, India, and elsewhere. Further investigations are required to enhance the generation of value added products (fuel) with low investments without affecting the environment. The paper reviews the available literature in this field of active research and identifies the gaps that need further attention. © 2009 Elsevier Ltd. All rights reserved.

The pyrolysis of eucalyptus wood was carried out in a batch reactor to optimize the yield of bio-oil. Effect of various parameters like feed (particle) size, temperature, presence of catalyst and heating rate on the yield of bio-oil was investigated. The optimum conditions for high yield of bio-oil are for the particle size 2mm~5mm (average l/d=12.84/2.03mm) at 450°C in high heating rate. The reaction kinetics and the quality of bio-oil produced are independent of the presence of different catalysts like mordenite, kaoline clay, fly ash and silica alumina. The physical properties like odour, colour, PH, viscosity, heating value were determined. The FT-IR analysis of bio-oil indicates the presence of different functional groups such as monomeric alcohol, phenol, ketones, aldehydes, carboxylic acid, amines, and nitro compounds. The composition of the bio-oil at different conditions was analyzed using GC-MS and found that the components are temperature dependent but independent of catalysts used.

Colloids and Surfaces A: Physicochemical and Engineering Aspects | Year: 2010

Natural kaolin was refluxed with sulphuric acid of different concentrations 1M, 3M, 5M and 10M at 110°C for 4h followed by calcination at 500°C for 2h. The physico-chemical characteristics of acid-leached kaolinite clay were studied by XRF, XRD, FTIR, TGA, DTA, SEM and N 2 adsorption techniques. XRF and FTIR studies indicate that acid treatment under reflux conditions leads to the removal of the octahedral Al 3+ cations along with other impurities. XRD of 5M and 10M treated kaolin shows that treatment with high concentrated acid provoked an amorphization resulting in the formation of an amorphous silica type phase. Leaching of Al 3+ ions increased progressively with severity of the acid treatment. The acid treatment increased the Si/Al ratio from 0.65 to 8.09, surface area from 23m 2/g to 143m 2/g and pore volume from 0.361cc/g to 1.18cc/g as the acid concentration was increased to 10M. Solids thus obtained by acid treatments can be used as promising adsorbents and catalyst supports. © 2010 Elsevier B.V.

Uniform approximation of signals has been an area of interest for researchers working in different disciplines of science and engineering. This paper presents an adaptive algorithm based on E. coli bacteria foraging strategy (EBFS) for uniform approximation of signals by linear combinations of shifted nonlinear basis functions. New class of nonlinear basis functions has been derived from a sigmoid function. The weight factor of the newly proposed nonlinear basis functions has been optimized by using the EBFS to minimize the mean square error. Different test signals are considered for validation of the present technique. Results are also compared with Genetic algorithm approach. The proposed technique could also be useful in fractional signal processing applications. © 2010 Springer-Verlag.
