Panorma of research and development of wines in India

 

 

 

 

 

 

 

 

 

 

 

 

 



v K Joshi & Devender Attri

In India, an impressive progress has been made in development of technologies for preparation of wines from grapes, mango, apple, peach, pear, plum, cashew-apple, pineapple, pomegranate, banana, ber, strawberry, and kinnow. Methods for the cider and wine including those with medicinal properties preparation from apple juice and its concentrate have been standardized. Deacidifying yeast (Schizosaccharomyces pombe) for making dry wine of acceptable quality and production of sparkling wines from plum, using immobilized S. pombe and foam stabilization by the use of yeast extract has successfully been made. An overview of the wine research, reflects that sporadic and inconsistent work is being carried out at different places in India and there are still a large number of research gaps. Consequently, the Indian wine industry is still in infancy and has to imbibe many developments made world over in the wine production.

Bülent Erdem & H Şebnem Başkan Düzgün

Draglines operate in a cyclic nature. Excluding the infrequent walking, a dragline spends its major operational time by digging the dirt and paying it out on a spoil pile. Dragline performs tens of thousands of cycles per year, even a small reduction in a single cycle time would result in a significant increase in productivity. Thus, it is to the benefit of a mine that dragline cycles need to be critically analyzed and corrective measures be taken. The study is based on field investigation conducted on six draglines with different capacities and operating modes. Stopwatch study is performed. Influence of cut dimensions, nature of material excavated, mode of digging, type of bucket employed, swing angle, operators’ judgements and condition of dragline on cycle time are analyzed.

Commercial and residential building energy labeling








 

 

 



M Siddhartha Bhatt, N Rajkumar, S Jothibasu, R Sudirkumar, G Pandian & K R C Nair

The paper presents base line date for labeling residential and commercial office buildings on the basis of electrical energy consumption. The study is based on a sample of eight typical residential buildings in Bangalore and five commercial buildings in New Delhi of varying built-up areas. The overall SEC is in the range 1-3 kWh/ m2/month for residential buildings and 5-25 kWh/m2/month for commercial buildings. If only building energy consumption is considered, it is in the range 0.3-1.0 kWh/m2/month for residential buildings and 3-10 kWh/ m2/month for commercial buildings. SEC/person is in the range of 300-800 Wh/m2/person/month for residential buildings and 3-6 Wh/m2/person/month for commercial buildings. Commercial building energy intensities are higher than domestic intensities. The energy consumption (winter-summer) varies between 30-100 % peak value due to variation in ambient temperature and weather conditions.

Synthesis of active goethite and maghemite from scrap iron sources






 


 

Rangadhar Nayak & J Rajagopala Rao

Investigations have been carried out on the oxidative hydrolysis of iron(II) chloride using Na2CO3 or NaOH. The products were subjected to hydrothermal agitation before being filtered and dried at 110oC. The samples were characterised by chemical analysis, surface area by nitrogen adsorption, thermal analysis and XRD. Samples prepared by different procedures and at different temperatures result in the formation of mixtures of goethite (a-FeOOH), maghemite (g-Fe2O3), e-Fe2O3 and Fe3O4 in varying compositions. All the samples at 4000C or above are converted to a-Fe2O3.

Use of zeolitic tuff in ceramic bodies








 



 



Aydın Aras

Zeolitic tuffs, clays from the Istanbul area, rhyolitic-dasitic tuffs from Çanakkale-Tepeköy area and feldspars from Çine area are used in the preparation of ceramic bodies. Clinoptilolite, quartz, feldspar, biotite and volcanic glass basically form the mineralogical composition of the tuff. The use of zeolitic tuffs was investigated in the fast fired ceramic bodies which are prepared by semi-dry pressing. The grain size and distribution of quartz content and inversion-conversion change influence physical properties of fired bodies. As firing shrinkage increases, water absorption decreases regularly by addition of more zeolitic tuff to ceramic bodies. İn spite of lower Si content of Çanakkale-Tepeköy tuff, the water absorption property is influenced differently by the Si content when it originates from quartz of Çanakkale- Tepeköy or glassy phase of Demirci-Gördes zeolitic tuff.

Rise in nitrous oxide levels due to fossil fuel combustion in urban atmosphere









 

 

Puspanjali Rout, R.Das & Surendra Nath Das

During the study period (2001-2003), the population of Bhubaneswar city increased about 3.9 % while the number of registered vehicles went up about 13 %. N2O concentration in air was above the ambient value (~419-428 ppbv) at most busy traffic posts. Similarly, at posts having low traffic density, the N2O level was (~228 ppbv). Wide variations were observed for N2O levels in the same station on different days because of varying traffic density. Seasonal variation could not be established due to less number of samples.

Biocidal activity of the essential oils of Lantana camara, Ocimum sanctum and Tagetes patula








Vidya S S Dharmagadda, Mamta Tandon & Padma Vasudevan

Essential oils of Lantana camara, Ocimum sanctum and Tagetes patula leaves were evaluated for antibacterial and antifungal activity. L. camara oil was also evaluated for larvicidal activity against different mosquito larvae. The growth of Bacillus megatarim and Staphylococcus aureus was inhibited at 1600 ppm. But, L. camara oil was able to inhibit the growth of Kliebsella sp only at higher concentrations compared to other two oils. L. camara oil was effective in inhibiting the growth of fungi, Aspergillus niger, and reducing the growth of other fungi. At a dosage of 200 ppm of oil, 100 % mortality of Culex quinquefasciarus larvae was obtained in 15 min.

Cellulolytic enzymes of Trichoderma lignorum produced on banana agro-waste: Optimisation of culture medium and conditions





M M V Baig

A culture medium with banana agro-waste comprising psuedostem and leaves as substrate is used for production of cellulolytic enzymes using Trichoderma lignorum (Tode) Harz. Banana leaves as carbon source give best results with an enzyme activity of 0.20 U/ml FPase, 0.41 U/ml CMCase, and 0.24 U/ml b-glucosidase, respectively. Soy peptone was found to be the most suitable nitrogen source for enzyme production. The optimum pH of medium was found to be 5.6–5.8, whereas 45°C was the optimum temperature.

V Saravanan & T R Sreekrishnan

The paper attempts to gain an insight in to the expectations and satisfaction of the stakeholders and the players in a multilateral S&T programme, namely the TOKTEN (Transfer of Knowledge through Expatriate Nationals) programme, through the content analysis of TOKTEN documents and also using cluster analysis technique. The technique provides the desired visibility in bringing out the sociology of perception of players and their synergy.

Development of specialty papers is an art: Mulberry paper from Indigenous raw materials─ Part XII


 

  

Dharm Dutt, A K Ray, C H Tyagi & Vivek Kumar

Mulberry paper is a highly specialized paper exclusively used for the manufacturing of wedding and greeting cards. Besides writing and printing properties, a few mechanical strength properties like folding endurance, burst factor and tear factor, are the most important properties for mulberry paper. The present paper aims at developing mulberry paper from locally available hard woods like Eucalyptus tereticornis, Populus deltoides and grass like Bambusa aurandacea from Assam origin.
