Tukra is one of the major problem in mulberry growing areas and it is caused by pink mealy bug Maconellicoccus hirsutus which affect both the quality and yield of mulberry leaf. A preliminary attempt has been made to control tukra in mulberry using plant extracts of natural pesticide origin. The seed kernel and leaf extracts of Azadirachta indica, Pongamia pinnata, Madhuca longifolia and only leaf extracts of Lantana camara, Adathoda vasica were directly used as a foliar spray in the control of tukra in M-5 mulberry variety. Total of four sprays were given with an interval of 7 days.

Rapid urbanization in the world is quite alarming, especially in developing countries such as India. In the present study historical change in urban area was analyzed using multi-temporal satellite images of 1980, 2000, 2010 and 2013 respectively to identify the areas where the increase or decrease has taken place over the period of last 33 years. High resolution satellite data of CARTOSAT 1 and 2 was used for base map and Digital Elevation Model generation.

Mulberry, Morus alba L., the only host plant of silkworm (Bombyx mori L.,) is attacked by about 300 species of insect pests. Among them, pink mealy bug, Maconellicoccus hirsutus Green is the most serious causing more than 35 per cent yield loss besides impairing nutritional quality of mulberry leaves. The management of pink mealy bug by using plant products is gaining attention due to proven specificity, biodegradability, low toxicity to non target organisms and low residual toxicity in the mulberry ecosystem.

A newly isolated Pseudomonas aeruginosa MTCC 4996 capable of degrading phenol Pseudomonas aeruginosa MTCC 4996 cells were immobilized with six different matrices. All the immobilized matrices showed faster degradation than free cells. Among the matrices, PUF immobilized cells showed maximum degradation followed by alginate and k-carrageenan, agarose, polyacrylamide and hen egg white. P. aeuriginosa MTCC 4996 cells immobilized with PUF were showed 100% degradation up to 1400 mg/l within 750 min.

Sustainability is the cry in today’s world by many concerned earth dwellers with a view of developing the earth’s resources in such a manner that it will not be depleted for future generations. Key to these developments is justice and equity regarding the redistribution of all goods and service on planet earth. The question is: What could theology and the church’s contribution be to this quest of sustainability of the earth’s resources?

Estuaries are important sinks of pollutants derived from anthropogenic activities. Fish inhabiting these areas have been proposed as sentinels for pollution monitoring through assessment of sensitive biomarkers. Biomarkers can be defined as a change in biological response, ranging from molecular through behavioural changes, which can be related to exposure or effects of environmental contaminants. The present study was focused to examine the histological changes in the comparatively in polluted samples collected from two different sites.

The study was conducted during the year 2013 with a specific objective i.e., to study the selected agro-economic, socio-psychological and communicational variables for identifying the areas requiring necessary interventions for enhancing ginger production within the study area. For the assessment of facts, 100 ginger growers i.e. marginal and small farmers have been randomly selected form five gram panchayats of Pulbazar-Bijanbari block of Dist.-Darjeeling, West Bengal. Pearson’s correlation co-efficient have been used as a statistical tool for analysis of the data.

Talus is the important tarsal bone which participates in the formation of talocrural, subtarsal and talocalcaneonavicular joints. In the subtalar region, anatomical variation is particularly present on the talus as well as on the calcaneus. The prior knowledge of anatomical setup of talus and its various articulations are significant in diagnosis of underlying pathology of the foot like Congenital telipes equinovarus, Pes planus, high arched foot etc. as a result there are changes in its morphology and also help in its treatment.

Dress codes vary widely, and many cultures have different and strong “modesty codes”. Many people have certain clothing expectations and, or thoughts about what is reasonable or justified for people to wear. When the majority of people share the same expectations in a society, standards form, and standards are guidelines and principles that set forth what’s appropriate, or suitable to wear. Dress is seen as a visible symbol for fundamental beliefs that can be influenced by several factors, therefore, resulting in various types of clothing styles that are worn.

The main moments of historic-ethnographical importance of development of the main traditional branches of craftsmanship of Ganja in this scientific work for the first time has been systematic investigated on the basis of innovative technologies and facts. Also were researched the basic skill characteristics of different wares of these traditional handicraft branches.
