Fungal metabolites as a natural source of herbicide: a novel approach of weed management: Ajay Kumar Singh* and Akhilesh Kumar Pandey Mycological Research Laboratory, Department of Biological Science Rani Durgawati University, Jabalpur-482001, Madhya Pradesh.

No full textWeeds are undesirable vegetation directly or indirectly inferring with human welfare. Conventional methods of weed control have failed due to one or other reason. Herbicide-resistant weeds are the main problem in weed control due to the number of weed biotypes resistant to herbicides that constantly increases by the continuous use of the same products for years. Development of alternative weed control methods is needed to help decrease reliance on herbicide use. Biological weed control is an alternative option for weed problems, particularly in agriculture and forestry. It is based on the use of natural enemies, particularly insects and pathogens to control weeds, as a sustainable, low cost and more environmentally acceptable method of weed control. One of the approaches to biological weed control using fungal phytotoxin applied in similar ways to conventional herbicides. Fungal phytotoxins are natural secondary metabolites produced by plant pathogenic fungi during host–pathogen interactions. They have received considerable particular attention for elucidating disease etiology, and consequently to design strategies for disease control. Due to wide differences in their chemical structures, these toxic metabolites have different ecological and environmental roles and mechanisms of action. This review aims at summarizing the studies on the possible use of fungal phytotoxin as a lucrative, novel source of secondary phytotoxic herbicidal compounds for management of broad spectrum, noxious and pernicious weeds
Evaluation and analysis of impact of subsidies on small scale renewable energy technologies dissemination: a case study of Nepal
No full textThe report has analysed the status of rural electrification using renewable energy technologies (RETs) and the current subsidy delivery modality of RETs in Nepal. As the Government of Nepal is subsidizing small scale renewable energy projects, it is important to evaluate and analyse the programme to make sure that a programme is running in an effective and efficient way while reaching the target group.
During the course of the research, primary information collected from the field has been compiled using appropriate tools/software (such as MS Office) and analyzed. Different sets of questionnaires were prepared, targeting different personnel ranging from the users’ level to the government policy level. The field survey methods include field observations of RETs installations and operations along with interviews with selected users on a random sampling basis to identify barriers to subsidy delivery and possible measures to overcome these barriers; to determine user satisfaction level and time period for subsidy delivery mechanisms.
The report started with the country background information and the rationale behind the study. This is followed by the literature review and information on the current status of small scale RETs in the country. Next it deals with the organizational structure and current subsidy delivery modality of RETs in the country. The evaluation of the effectiveness of the subsidy with the current subsidy delivery modality has been analyzed based on six parameters; Targets and Achievements, Impact of RETs, Subsidy Delivery System Efficiency, Transparency, Sustainability and Effectiveness.
The research shows that the subsidized government program has been successful in achieving its goal to provide basic energy services in rural areas through RETs in terms of its quantitative target. Although the subsidized program is successful in electrifying the rural communities via RETs, the poorest of the poor families are still excluded from the subsidy. The program seems to benefit more the rich and upper middle class families rather than the poor families for which the subsidy was intended. The high capital cost and long subsidy delivery process are the main important reasons for this failure. The author has proposed a new modality which might overcome the time barriers and bureaucratic process in the subsidy delivery mechanism and will decrease the lead time. This will in turn help to reduce the operational cost of the private companies and will encourage more players to enter the market, increase competition and result in lower system costs.
After identifying gaps in the current subsidy delivery modality, the project report ends with the recommendation of a new modality improving the current modality and filling the gaps identified. As this study has some limitations, as described in chapter one, the scope of further works has been listed at the end
Root-Galling Disease of Vegetable Plants
No full textThis book provides the most comprehensive and up-to-date review of research on vegetable plants associated with root-galls disease caused by root-knot nematodes (RKNs), Meloidogyne spp. Vegetables retain a key position in cultural cuisines and their consumption worldwide due to rich sources of micronutrients, including vitamins, minerals and antioxidants, but root galls disease of these crops caused by RKNs steals both quantity and quality from production. The field of plant nematology has experienced exponential growth over the past decade, and these RKNs are now known as widely damaging obligate plant parasites of vegetable plants. Advances are being made in understanding their biology, parasitism in the root system, giant cell development, root gall formation, chemical signalling, root-knot disease complexes, and management systems.
This compilation provides an invaluable resource for studying root-galls disease of vegetable plants to those readers associated with plant nematology, plant pathology, plant protection, and agricultural science, including researchers, teachers, advanced undergraduates and graduate students, and even agricultural extension agents and farmers.Contiene: Front Matter (i-xix).-- 1.

Small Group Research, 51(6), 659–699. https://doi.org/10.1177/1046496420934541. This article was originally published in Small Group Research. The version of record is available at: https://doi.org/10.1177/1046496420934541. © The Author(s) 2020.At its 50-year milestone, we assess the Small Group Research (SGR) corpus to reflect on the development of group research over the past half century. To do this, we examine the evolution of the corpus’s context and content. We examine its context by assessing its impact, which journals it communicates with, and the internationality of its authors. We examine its content—the topics discussed in its articles—using keyword clustering and co-occurrence network analysis. We identify 10 research communities and track their relationships over the four editorial periods associated with the SGR corpus (lagged 2 years for influence): 1970–1981, 1982–1991, 1992–2010, and 2011–2019. Our analyses indicate that the global and local study of group dynamics has fluctuated over time and that phenomenologically based topics connect theoretical topics and stimulate theoretical development. We also provide three criteria to identify communities and topics of group research most likely to benefit from future integration.The author(s) received no financial support for the research, authorship, and/or publication of this article

Addiction Eradication: A Systematic Approach to Save New Generation
No full text<div><p>The article elaborates the menace of Tobacco/drug addiction. Tobacco is considered as the first step towards any drug addiction. Tobacco kills more than tuberculosis, HIV/AIDS and malaria combined. 71% of all Lung cancer deaths are attributable to tobacco use. The proposed “Simplified Addiction Trap Model” highlights the process of addiction. By implementing the suggested low cost model, the addiction can be eradicated in new generation which will ultimately result in total addiction eradication in coming years. </p></div></jats:p
