The objectives of the present study were to determine the free radical scavenging activity, total phenolic and flavonoid contents in leaves, stem and roots of U. picta. Powdered samples of leaves, stem and roots were subjected to successive extraction with solvents of increasing polarities i.e. Ethanol, Water: Ethanol (Aqua- alcoholic) (20: 80) and Water (aqueous) using soxhlet apparatus. Total phenol, flavonoid and antioxidant activity were determined by using Folin-Ciocalteau method, aluminum chloride colorimetric technique and DPPH free radical scavenging methods respectively. The results exhibited the maximum phenolic (1.991±0.299%) and flavonoid (2.865±0.11%) contents in ethanolic extract of leaves. For stem, the highest phenolic content (1.208±0.115%) and highest flavonoid content (22.189±2.7%) were detected in aqueous and ethanolic<br>extracts respectively. For roots, both the maximum phenolic (3.554±0.004%) and flavonoid (0.497±0.507%) contents were found in Aqua- alcoholic extract of roots. The ethanolic extracts of leaves and stem and aqueous extract of roots were found to contain the lowest IC50 and hence, the maximum antioxidant activity. Based on the findings, it can be concluded that among the different extracts of leaves, stem and roots of U. picta, the ethanolic extracts of leaves and stem and aqueous extract of roots exhibited the more promising antioxidant activity due to the presence of phenolic and flavonoid compounds.</p> B.

The invasion of alien plant species can be facilitated by many eco-climatic factors. The present study was conducted to assess patterns and trends of invasion by Ageratina adenophora in major land use and land cover types; in Gokerneshwergad watershed of Kailash Sacred Landscape (KSL) in western Himalaya. Extensive surveys were conducted to map the species in each season and habitat type. Sites with high biotic pressure and open forest canopy were the most suitable habitats for its growth. A negative correlation was found between distribution and altitude. The highest invasion was recorded in between 1700 – 1800m elevation gradient, between 20° and 30° slope positions and at North (33.33%), whereas, the lowest invasion was recorded between 700 – 800m in South-East directions (3.70%). Several other parameters such as distance from the disturbance site such as road, villages or settlements, drainage and soil texture were also found to be affecting the distribution pattern of this species. Interestingly results reveal that the alien plants also start competing among themselves after reaching their threshold level.</p> Alka Chaudhary B.S Adhikari N.C. Joshi G.S.

Today, in the time of new technology, it is almost impossible to imagine life without these devices like mobiles, laptop, fridge, microwave ovens, air conditioners etc there is no strong solution to the radiation generated at the time of production and consumption of these devices. At the time the solution to reduce internal and external air pollution is found in our Indian scriptures as YAGYA. Veda is the pillar of Indian culture and human life .facts mentioned in Vedas are proven and important in the CHANDOGYA UPNISHAD, Yagya has been described as the best means of resolving environment pollution. It is said that about Yagya that is removes all impurities and pollution and makes it pure. The Havan Samegri used in the Yagya is burnt in fire and spread everywhere with the help of air removes contaminated air and creates a fragrant environment. In the modern era, it has become clear from the researches on Yagya that the number of particulate matters(which is harmful for human body and are responsible for lungs and heart diseases) are decreased by sacrificing some special wood like mango etc. It was observed that after performance of Yagya there was a significant decrease in the indoor EMR (Electromagnetic Radiation) level indicating a utility of Yagya as nonconventional solution for reducing indoor EMR level. Foreign scientist TRILVERT has said in his research that the sweet material like sugar used in Yagya has extraordinary power to purify the air.</p> Devender Kumar Copyright (c) 2019 (C) ASEA https://creativecommons.org/licenses/by-nc/4.0/ 2019-12-27 2019-12-27 20 3 57 60 10.36953/ECJ.2019.20308 Status of migration in Uttarakhand: A case study of Rudraprayag District https://journal.environcj.in/index.php/ecj/article/view/95 <p style="text-align: justify;">Migration is one of the important dimensions in constructing population dynamics in any region. Migration is often the outcome of numerous multidimensional factors. They might be physical, economic, socio-cultural political factors or blend of one or more. In the present time economic factors are main responsible factors behind the migration in the developing and under developed countries. Migration has a direct impact on the population size of areas of origin and destination (Goldscheider, 1987). The entire Himalayan region is completely affected by migration and the state of Uttarakhand is no excetion to this, which has shown a constant increasing trend in intra rural urban migration since its formation in 2000. The Rudraprayag region in Uttarakhand is one of the rugged terrain areas with harsh climatic conditions and limited employment opportunities. Therefore, the study tries to analyses the migration trend in the area based on the primary survey of 16 villages. The maximum share of migrants is due to job and employment which makes<br>up to 13.58% in the region. Education is the second most important region with 11.13% due to which people tend to migrate in the region especially the younger population. The migration condition of Rudraprayag district is presented in this paper.</p> Ashutosh Jangwan Pallavi Upreti Copyright (c) 2019 (C) ASEA https://creativecommons.org/licenses/by-nc/4.0/ 2019-12-27 2019-12-27 20 3 61 72 10.36953/ECJ.2019.20309 Four pyrophytic pteridophytes in the Chir pine forest of Kalidhar forest range in Shiwaliks of North West Himalaya in Indian Himalayan region. https://journal.environcj.in/index.php/ecj/article/view/96 <p style="text-align: justify;">Fire always plays a significant role in the secondary succession and maintenance of various communities or ecosystems on earth, like grass community, understorey community in a forest and on a large perspective forest ecosystem. Vascular cryptogams form an important group of plants that is recovered very rapidly after the fire events. This is perhaps due to their rhizomes lying below the ground surface, which are able to evade the fire stress. Current study deals with presence of four pyrophytic (fire–tolerant)&nbsp; teridophytes in Kalidhar forest range at Jammu district.</p> Pallvi Sharma Harish Chander Dutt Bikarma Singh Copyright (c) 2019 (C) ASEA https://creativecommons.org/licenses/by-nc/4.0/ 2019-12-27 2019-12-27 20 3 73 77 10.36953/ECJ.2019.20310 Ichthyofaunal diversity of Tumaria reservoir, Kashipur, U.S. Nagar (Uttarakhand) https://journal.environcj.in/index.php/ecj/article/view/97 <p style="text-align: justify;">Present study was carried out to examine the diversity of fish fauna in Tumaria reservoir, Kashipur, U.S. Nagar, Uttarakhand, India.

Even though jackfruit is a pack house of nutritional components, it remains underexploited and facing huge postharvest loss. Jackfruit bulb and seed are rich in carbohydrates, proteins, fibre and other bioactive compounds and can be utilised for the development of value added products with health benefits and jackfruit pasta is promising as demand for nutritious pasta is increasing domestically as well as internationally. The present study aimed to develop red amaranthus enriched functional jackfruit pasta with natural red colour, nutritional qualities and consumer acceptability. The red amaranthus paste was added in two different proportions (5% and 10%) to different formulations of jackfruit pasta&nbsp; comprising of jackfruit bulb flour, seed flour and cassava flour replacing a portion of refined flour. The enrichment with 10% of red amaranthus as paste to jackfruit pasta formulations reduced cooking loss, improved the cooking quality characters, nutritional quality, and sensory attributes and produced naturally coloured pasta with higher consumer acceptability.</p> B.S Swathi G.P.R Lekshmi M.S.

Due to its lowest water and nutrient requirement, it has the potential for agriculture diversification. Nutritionally, proso millet grains are rich in proteins, vitamins, minerals, and micronutrients compared to other staple cereals. Recently the demand of the crop has increased due to its highly nutritious grains. Thus it has the potential to provide both food and nutritional security. Despite enormous potential, the crop has not gained the popularity among masses and is still considered as poor man’s food. This work therefore is an attempt to compile the merge information available on crop history, phylogeny, germplasm resources, and present status to make the crop comprehensive and revamp its cultivation.</p> S.

India is major producer of potable and industrial alcohols. The majority of distilleries use molasses as a feed stock. Ethyl alcohol is an important feed stock for the manufacturer of various chemicals. The effluent from the distillery is described as spent wash/vinasse. It was recognized in 2001 by the CPCB that concentrating or drying the spent wash and burning it with ancillary fuel, with energy recovery in the form of steam, is the most attractive alternative as a fertilizer. Distillery Spent Wash (DSW) is a rich source of organic matter and nutrients like nitrogen, phosphorus, potassium, calcium and sulfur. In addition, it contains sufficient amount of micro-nutrients such as iron, zinc, copper, manganese, boron, and molybdenum. Vinasse incineration can claim to be the best viable solution to treat distillery vinasse economically to meet the zero liquid discharge target of the industry. This review indicates that a wide range of<br>biological as well as physicochemical treatments, over the years for the treatment of distillery spent wash. No single technology can be employed for absolute treatment of distillery spent wash. There is a need to use a mix of treatment options with adequate protocols and guidelines so that spentwash can be gainfully utilized for biogas generation, biocompost, ferti-irrigation, one time land application, irrigation, sodic land reclamation and co-processing.</p> S.
