A dynamic price model based on levelized cost for district heating

District Heating (DH) is facing a tough competition in the market. In order to improve its competence, an effective way is to reform price models for DH. This work proposed a new dynamic price model based on the levelized cost of heat (LCOH) and the predicted hourly heat demand. A DH system in Sweden was used as a case study. Three methods were adopted to allocate the fuel cost...

Public perceptions of shale gas in the UK: framing effects and decision heuristics

Using two equivalent descriptions of the shale gas development process, we asked individuals to indicate their levels of support as well as their perceptions of the risks and costs involved. In version 1, shale gas development was framed as ‘fracking’, whereas under version 2 it was framed as ‘using hydraulic pressure to extract natural gas from the ground’. We find that...

Combinatorial application of ammonium carbonate and sulphuric acid pretreatment to achieve enhanced sugar yield from pine needle biomass for potential biofuel–ethanol production

Lignocellulosic biomass (LB) despite its huge potential as a renewable bioenergy resource faces bottlenecks due to its recalcitrance and lack of appropriate pretreatment approaches. The current study evaluates the combinatorial application of alkali and acid pretreatment of pine needle biomass (PNB), for achieving high sugar release upon enzymatic saccharification. Pine needle...

Solar air heater for residential space heating

Space heating appliances require significant amount of primary as well as secondary energy. In most of the countries, energy requirements for such utilities are met by burning fossil fuel or from conventional electricity. Such usual practices for space heating result in significant increase in greenhouse gas emission and fossil fuel depletion. In the line of global emphasis on...

Global carbon inequality

Global climate change and inequality are inescapably linked both in terms of who contributes climate change and who suffers the consequences. This fact is also partly reflected in two United Nations (UN) processes: on the one hand, the Paris Agreement of the UN Framework Convention on Climate Change under which countries agreed to hold the increase in the global average...

Potential application spectrum of microbial proteases for clean and green industrial production

Enzymes are the cornerstones of metabolism and constitute the fundamental basis for existence of life. However, recently enzymes are being implicated in diverse industrial processes because of their specific and fast action for efficient bioconversion of substrate to product, and their capability to save raw materials, energy and chemicals for various manufacturing processes...

Insights into the impacts of four current environmental problems on flying birds

A wide variety of substances and agents are released into the atmosphere due to anthropogenic activities. Higher levels of such entities have given rise to four major environmental problems: air, light and noise pollution and global warming, all of which severely affect birds and other animals. These four issues have been overlooked, although climate change is receiving...

Traditional agriculture: a climate-smart approach for sustainable food production

Sustainable food production is one of the major challenges of the twenty-first century in the era of global environmental problems such as climate change, increasing population and natural resource degradation including soil degradation and biodiversity loss. Climate change is among the greatest threats to agricultural systems. Green Revolution though multiplied agricultural...

Swimming characteristics of gyrotactic microorganisms in low-Reynolds-number flow: Chlamydomonas reinhardtii

The swimming characteristics of gyrotactic microorganisms are significant to understand the ecological activities in lakes, rivers and oceans. The swimming velocity of a typical motile microorganism, Chlamydomonas reinhardtii, was measured for both still water and low-Reynolds-number flow, based on a microfluidic system. Results show that the swimming speed is subject to Gaussian...

Implications of SiO2 nanoparticles for in vitro biodegradation of low-density polyethylene with potential isolates of Bacillus, Pseudomonas, and their synergistic effect on Vigna mungo growth

In the natural environment, low-density polyethylene (LDPE) contamination is one of the major sources of pollution and creates the hazardous threat. Biodegradation is an eco-friendly approach to control such type of pollution and maintain the sustainable environment. The presence of nanoparticles influences the growth ability of polymer-degrading microbes. In the present study...

Tracing China’s energy flow and carbon dioxide flow based on Sankey diagrams

China has promised to optimize its energy structure and reduce its CO2 emission in the 13th Five-Year Plan. To track the energy structure, the conversions, efficiencies, end consumptions of total energy and coal and the whole CO2 emission status, the energy flow, coal flow and CO2 flow in 2015 were, respectively, drawn at the national level based on Sankey diagrams. Besides, each...

Biohydrogen production by locally isolated facultative bacterial species using the biomass of Eichhornia crassipes: effect of acid and alkali treatment

Hydrogen (H2) produced from biological methods is a potential option to meet the growing clean energy needs. The present study aimed to produce biohydrogen by dark fermentation from nuisance aquatic weed, Eichhornia crassipes, using facultative anaerobic bacteria. A total of 12 bacterial strains were isolated from different wastewater sources and were screened for the potential...

Effect of altitudinal gradients on forest structure and composition on ridge tops in Garhwal Himalaya

Ridge top ecosystems (RTEs) are considered to be more sensitive to global warming as they are characterized by uniform sunlight exposure and low human interferences and hence are perfect places for monitoring and comparing the effects of climate change in species composition. The present study was carried out on RTEs of four different mountain ranges, viz. (1) Narendranagar...

Litter decomposition in forest ecosystems: a review

Litter decomposition in terrestrial ecosystems has a major role in the biogeochemical cycling of elements in the environment. Climatic features, like temperature, rainfall, humidity, and seasonal variations affect the rate of litter decomposition. This review attempts to understand the litter decomposition process in tropical forest ecosystems. It also reviews the influence of...

Determination of optimum life span of container houses by using Neuro-Fuzzy methods
