Composting is a useful waste treatment for environmental problem, but composting experiment is challenging due to large-scale requirement. Thus, laboratory-scale reactor is of interest for composting experiment. The capability of laboratory-scale reactor to simulate large-scale composting was determined by assessing the quality of produced compost via germination index.

Green synthesis method is being increasingly used in the development of safe, stable, and eco-friendly nanostructures with biological resources. In this study, extracellular and intracellular synthesis of gold nanoparticles (AuNPs) was carried out using green algae Chlorella sorokiniana Shihira & R.W. Fresh algae were isolated and identified from Musaözü Pond located in the province of Eskişehir and then extraction process were performed.

Molecular knowledge regarding the primary esophageal achalasia is essential for the early diagnosis and treatment of this neurodegenerative motility disorder. Therefore, there is a need to find the main microRNAs (miRNAs) contributing to the mechanisms of achalasia. This study was conducted to determine some patterns of deregulated miRNAs in achalasia. This case-control study was performed on 52 patients with achalasia and 50 nonachalasia controls. The miRNA expression profiling was conducted on the esophageal tissue samples using the next-generation sequencing (NGS).

In Vietnam, lotus plants are widely grown and some parts of the lotus plant have been used in traditional folk medicine. This herb is easy to find, inexpensive, non-toxic and is appreciated by local residents. However, thus far in Vietnam, few in the population know that lotus leaf can be used to prevent and treat obesity. The present study was designed to evaluate the anti-obesity effects of lotus leaf in mice.

The study was carried out during 2013-14 in Meerut district of Uttar Pradesh state to focus on the sugarcane growers regarding impact of knowledge on adoption level of IPM practices. The 80 contact farmers were selected as respondents. The study revealed that the maximum knowledge gap was found to be existing in previous crop residues, crop rotation, hand picking of the insect and their destruction, hot air and water treatment, light and pheromone trap, microbial control, use of natural enemies, resistant varieties, biopesticides/ bio-agents, application and dose of different pest etc.

An understanding of soil microorganisms as part of soil system and interactions between the diversity of producers and of decomposers, have major consequences on the functioning of agricultural ecosystems. Soil microorganisms control the transformation and mineralization of natural compounds and xenobiotics. The soil micro biota, existing in high density and diversity, rapidly modify the energetic performance and activity rates to changing environmental conditions.

Slow sand filtration has been an effective means of treating water for the control of microbiological contaminants. Schmutzdecke is the layer of the microbial community that is responsible for treating the water through the sand bed. As water passes through this biological layer, foreign particles are trapped and essentially eaten by bacteria forms on this layer. Development of Schmutzdecke layer depends on available microbes in raw water, food supply, oxygen supply, residence time, and wetting of sand bed.
