Those rock mass that are relatively unjointed and massive are exposed to the brittle failure, which is famously known as rock spalling/ rock bursting phenomenon. Establishing state of the stress and evaluating stress-induced instability in tunnels passing through such rock mass at relatively greater depth is therefore a challenge. The aim of this manuscript is to describes existing brittle failure (rock burst) prediction methods that are being practiced worldwide and propose necessary editions so that quality of assessment is enhanced. The methods described are very practical and the author is confident that professional engineers will use them to evaluate and predict potential rock burst/ rock spalling scenario in the tunnels during planning, design and construction phases. Each method of prediction is explained, applicability extent is highlighted and comparisons between the methods are made.

However, the energy law and policy emerge as a concern all over the world and states are taking initiative to ensure a balance among these three dilemmas. It is the reality that Bangladesh suffers severe shortage in power generation which also affects its overall economic development. Hence, in one hand, it needs to ensure continuous energy supply which is closely connected with country’s energy security also. On the other hand, it also needs to make a balance between the challenges of producing energy in affordable cost which will not adversely affect the environment as well. Nevertheless, Bangladesh, being a lower-middle income country at least put focus on the energy law and policy triangle in recent years. Still ensuring balance among these three opposite directions is still a challenge for Bangladesh. Despite that, the recent laws and policies relating to energy in Bangladesh show its commitment towards climate change mitigation which encourages more production and use of renewable energies in the country. Although there are some deficiencies in those laws and policies which can be overcome by further initiative. The State can reaffirm its position towards environmentally friendly affordable energy by amending those policies and legislations. This research paper is aimed to assess the dilemma of the Energy Law and Policy Triangle in recently legislated energy related laws and policies in Bangladesh.HYDRO Nepal JournalJournal of Water Energy and EnvironmentIssue No: 22Page: 10-15Uploaded date: January 14, 2018","PeriodicalId":117617,"journal":{"name":"Hydro Nepal: Journal of Water, Energy and Environment","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-01-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125561521","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In Nepal only six municipalities i.e. Kathmandu, Lalitpur, Pokhara, Dhankuta, Tansen and Ghorahi practice sanitary landfill for waste management and other municipality practices open dumping which has become major cause of environmental and human health hazards (ADB, 2013).Jeetpur Simara Sub-Metropolitan City (JSSMC) is a recently formed sub-metropolitan city. This city has not performed any study on solid waste management till date and lacks data on quantity and composition of municipal solid waste generation that facilitates effective planning of municipal solid waste management. The household survey revealed an average per capita household waste generation rate of 120 g/capita/day. The total Municipal Solid Waste (MSW) generation is estimated about 15 tons/day and 5475 tons/year. The analysis of household waste composition indicated that the highest waste category was organic waste with 80% followed by plastics with 10%, paper and paper products with 6% and inert with 4%. The composition analysis of institutional wastes revealed 41% paper and paper products, 33% plastics, 13% organic wastes and 13% inert. The study found that commercial waste comprised 59% paper and paper products, 21% plastics, 17% organic and 3% inert. In aggregate, MSW is composed of 56% organic waste, 21% paper and paper products, 19% plastics, and 3% inert.

Isolated Micro-hydro power plants are extensively used in these areas. This paper addresses the problem of deficient electricity during peak period in existing conventional micro-hydro plants by the introduction of battery storage in the plant. Micro-hydro plant with battery bank storages surplus power, which would be wasted in case of conventional micro-hydro plant, during off- peak period and supplies during peak period. The control strategies for Electronic Load Controller (ELC), three - phase ac/dc converter and buck converter are realized in Matlab Simulink environment. The simulated system was able to store surplus power into battery bank when load demand was less than power generated by Synchronous Generator (SG) and supply when the load demand was higher than generator’s generation. This model can be implemented in the already existing micro-hydro plants where the load demand for a short time has increased beyond generation capacity of generator.
