Résumé :

Tea is the most consumed beverages after water. In Terai and Dooars region of sub Himalayan West Bengal, India, tea plantations are around 150 years. Exploitation of tea garden soil over centuries has led to decline in soil fertility and crop productivity after all initiatives of external inputs. As nutrients play a crucial role in quality and quantity of manufactured tea, the present initiative has been designed to quantify the soil nutrient status of tea growing Terai and Dooars region. 79.62% (Terai) and 84.72% (Dooars) of the soil samples were found to have normal pH. 47.21% (Terai) and 49.3% (Dooars) of soil samples was found to have normal organic carbon. 12.03% and 20.82% of soil from Terai and Dooars showed low total nitrogen. Both the organic carbon and nitrogen in soil are positively correlated. Phosphorus (as P2O5) content of soil is extremely site and depth specific. Almost all samples of the study area showed high potassium (as K2O) content. Monoculture, change in rainfall pattern and inorganic additives have contributed enormous stress to soil but despite of all these odds the overall nutritional richness of these tea growing regions seems to be satisfactory.

Résumé :

A small village named Murti is situated along the bank of river Murti in Dooars. The adjacent area of murti is rich in insect biodiversity. Knowledge on the diversity and the role of Orthopteran insects in tea ecosystem of West Bengal including Dooars and Terai is very scanty. Hemocytes are the chief immune cells of insects. The number and shape of hemocytes can change rapidly in response to environmental stress and pollution. Grasshopper (Orthoptera) species were collected from Murti and adjoining areas and from different agricultural fields of North 24 Parganas (West Bengal). Hemolymph was stained by Giemsa, and Neutral Red. Cellular morphology and phagocytosis was examined. Normal cell shape and behavioural activities like phagocytosis, cell-cell fusion was observed in insects collected from Murti, and adjoining areas of Dooars. But in case of insect hemocytes isolated from different agricultural fields of North 24 Parganas and its adjacent sites showed altered shape and different phases of cell death like degeneration of nuclei, formation of membrane blebs and rupture of plasma membrane. Toxic environmental pollutants may be responsible for alteration of hemocytes size and function which may effect on biodiversity. Hemocytes can be used as an effective bio-indicator by which the health of the ecosystem can be screened.

Résumé :

There is always a need for novel, high quality, functional and inexpensive foods among consumers in the global markets. Leafy vegetables can fulfill such needs. Leafy vegetables are now used worldwide as food for their nutritional and medicinal values. In the present work an ethnobotanical survey was carried out on the utilization of edible plants by local communities of the Terai-Dooars Region of West Bengal. The information has been documented by interviewing traditional farmers, herbalists, various older men and women following different ethnobotanical methods. A total of 103 plant species under 44 families with their short botanical description, use, range of demands and cultivation status have been documented.

Résumé :

Tea [Camellia sinensis (L.) O. Kuntze] is one of the important contributors to the growing economy of NorthBengal. The phytochemical and therapeutic qualities of tea prominently altered recently due to continuous change in climatic conditions of North Bengal. The nutraceutical quality of tea is largely dependent on antioxidant attributes. For investigating the relationship between antioxidant attributes and climatic factors, the present field experiment was conducted in 18 tea gardens of Terai, Dooars and Darjeeling Hills of North Bengal during 2012–17. Antioxidant and phytochemical analysis was performed in three different harvest seasons, viz. March, June and December. Phenolic compounds including catechins were low during winter months, and then gradually increased up to warmer spring season. In stress condition, tea plants biosynthesized more flavonoids and high flavour index in Darjeeling hills. However, free-radical scavenging and metal chelating activities were found to increase from spring to winter season. The data were pooled for PCA analysis to determine the relationship between seasonal variations and tea antioxidant quality in each region of North Bengal separately. Different attributes of climatic factors significantly correlated with antioxidant quality and bioactive compounds. Variation in climate is reportedly affecting the antioxidant quality of tea and its shifting pattern grossly influences the key phytochemicals responsible for the flavour of tea.

Résumé :

This paper discusses thrust reversing techniques for a separate exhaust high bypass ratio turbofan engine and its effect on aircraft and engine performance. Cranfield University is developing suitable thrust reverser performance models. These thrust reverser performance models will subsequently be integrated within the TERA (Techno-economic Environmental Risk Analysis) architecture thereby allowing for more detailed and accurate representations of aircraft and engine performance during the landing phase of a typical civil aircraft mission. The turbofan engine chosen for this study was CUTS_TF (Cranfield University Twin Spool Turbofan) which is similar to the CFM56-5B4 engine and the information available in the public domain is used for the engine performance analysis along with the Gas Turbine Performance Software, ‘GasTurb 10’ [1]. The CUTEA (Cranfield University Twin Engine Aircraft) which is similar to the Airbus A320 is used alongside with the engine model for the thrust reverser performance calculations. The aim of this research paper is to investigate the effects on aircraft and engine performance characteristics due to the pivoting door type thrust reverser deployment. The paper will look into the overall engine performance characteristics and how the engine components get affected when the thrust reversers come into operation. This includes the changes into the operating point of fan, booster, HP compressor, HP turbine, LP turbine, bypass nozzle and core nozzle. Also, thrust reverser performance analyses were performed (at aircraft/engine system level) by varying the reverser exit area by ± 5% and its effect on aircraft deceleration rate, deceleration time and landing distances were observed.
