Aim:
To develop a method for the isolation and enrichment of bacteriophages selectively against speciÞc bacteria coupled with a membrane Þltration technique. Methods and Results: Rapid isolation and concentration of host-speciÞc bacteriophages was achieved by exposure of the sample suspected to contain bacteriophages to a speciÞc host immobilized on a 0 45 lm membrane in a membrane Þltration unit. The principle behind this method is the exploitation of host-speciÞc interaction of bacteriophages with their host and maximizing this interaction using a classic membrane Þltration method. This provides a chance for each bacteriophage in the sample to interact with the speciÞc host on the membrane Þlter Þtted with a vacuum pump. SpeciÞc bacteriophages of the host are retained on the membrane along with its host cells due to the effect of adsorption and these adsorbed bacteriophages (along with their hosts) on the Þlter disc are then ampliÞed and enriched in regular nutritive broth tryptose soya broth by incubation. With the help of the plaque assay method, host-speciÞc phages of various bacterial species were isolated, segregated and enriched.
Conclusions:
The phage concentration method coupled with membrane Þltration immobilization of host bacteria was able to isolate and enrich the host-speciÞc bacteriophages by several fold using a lower quantity of an environmental water sample, or other phage suspensions. Enrichment of phages from single plaques was also achieved. Significance and Impact of the Study: The isolation and detection of host-speciÞc bacteriophages from a low density bacteriophage water sample in a single step by the use of a simple and basic microbiological technique can be achieved. Enrichment of phages from low phage titre suspensions is also achieved very effectively.

This addendum to "Novel application of bacteriophage for controlling foaming in wastewater treatment plant- an eco-friendly approach " includes characteristics of the phages NOC1, NOC2 and NOC3 not discussed in the previous paper. The phage adsorption and host interaction properties, their sensitivity to pH and temperature are inferred. NOC2 is seen to be more temperature resistant while others are not. All the phages show pH sensitivity. There is a variance observed in the behavior of these phages. Also, applicability of the phage based system to large scale reactors is studied and discussed here.

Mesoscale atmospheric circulations play an important role in the transport of air pollution and local air quality issues. The planetary boundary layer (PBL), the thermo-dymamical structure and the flow field play an important role in air pollution dispersion. Hence, the PBL parameters over Nagpur, India are simulated using the ARW v. 3.6.1 mesoscale model. High-resolution simulations are conducted with triple nested domains having a horizontal resolution of 27, 9 and 3 km, as well as 27 vertical levels by using the 1 × 1° NCEP Final Analysis meteorological fields for initial and boundary conditions. Eight fair-weather days in winter and summer (January and April 2009) with no significant synoptic activity were chosen for the study. Sensitivity experiments of the ARW model were conducted with two non-local (Yonsei University [YSU], and Asymmetric Convective Model v. 2 [ACM2]) and three local turbulence kinetic energy (TKE) closure (Mellor-Yamada Nakanishi and Niino Level 2.5 PBL [MYNN2], Mellor-Yamada-Janjic [MYJ], and quasi-normal scale elimination [QNSE]) turbulence diffusion parameterizations, to study the evolution of PBL parameters and the thermodynamical structure during the study period. After validation of the simulated parameters with the available in situ data, it was revealed that the non-local PBL scheme YSU, followed by local scheme MYNN2, could be able to capture the characteristic variations of surface meteorological variables and the thermodynamical structure of the atmosphere. The present results suggest that PBL schemes, namely YSU and MYNN2, performed better in representing the boundary-layer parameters and are useful for air pollution dispersion studies.

Laryngeal cancer disproportionately affects more African-Americans than European-Americans. Here, we analyze the genome-wide somatic point mutations from the tumors of 13 African-Americans and 57 European-Americans from TCGA to differentiate between environmental and ancestrally-inherited factors. The mean number of mutations was different between African-Americans (151.31) and European-Americans (277.63). Other differences in the overall mutational landscape between African-American and European-American were also found. The frequency of C>A, and C>G were significantly different between the two populations (p-value < 0.05). Context nucleotide signatures for some mutation types significantly differ between these two populations. Thus, the context nucleotide signatures along with other factors could be related to the observed mutational landscape differences between two races. Finally, we show that mutated genes associated with these mutational differences differ between the two populations. Thus, at the molecular level, race appears to be a factor in the progression of laryngeal cancer with ancestral genomic signatures best explaining these differences.

A flush urinal-toilet disposes human waste by using water through a drainpipe to another location. A series of urinal-toilets are fitted in offices, malls, multiplexes, educational institutions, bus railway stations, airports, commercial complexes, stadia and other public places. Most have manual flushing systems like push button, trigger, pull chain, etc. however, use of such manually operated flush can spread germs and bacteria when contacted and thus users avoids to flush or lead to wastage of water if used. Now a day’s laser or infrared sensor operated flushes is also used in the places of high commercial value and importance but are expensive and required continuous O&M. Therefore, the sanitary facility may remain un-flushed leading to unhygienic conditions and foul smell. Thus need for a low cost automatic flushing apparatus which can flush the right-controlled amount of water and avoid direct contact thus conserving water as well as maintaining personal hygiene and sanitationThe present invention relates to a specially designed mechanical automatic urinal-toilet flusher and a mechanism thereof, which utilizes the weight load/pressure of the person using the urinal-toilet for automatic flushing the urinal- toilet with the specified or measured quantity of water to prevent odors, soil drain and scale buildup. It ensures the compulsory, regular and un-intentional flushing of the urinal-toilet without any direct hand contact of the user to the flush and also conserve water at the same time is simple and cheap, which can be fitted-retrofitted to new as well as existing water pipe line of the urinal-toilets.

Waste management system in India at present is taking a significant change. Majority of the problems are associated with the management of municipal solid waste, E-waste and CD waste. Though the MSW rules 2000 were implemented long back, the rules pertaining to e-waste management has been implemented in 2012. All the rules related to waste management are undergoing revision at present which is expected to lead to a sea change in effectiveness in addition to some new rules in the country. The traditional system of landfilling or dumping is now being replaced by different waste treatment processes. This paper deals with two case studies, of a E-waste recycling plant and a Bio-methanation plant in India, which were studied by a visiting team from the recently held IconSWM 2015 in Bangalore. It has been observed that both the plants are running effectively to curb the disposal of wastes into dumping grounds as well as recover materials and energy. This study will present the materials and energy recovery processes adopted in both the plants and proposed methodologies to make the systems more effective. This study will also highlight the general and specific issues and challenges related to E-waste recycling and biomethanation plants and elaborate on how to overcome those. The results of the study will help the researchers and implementers for further actions.

Desktop personal computer (PC) is one of the major contributors of the waste electrical and electronic equipment’s (WEEE) generated worldwide. Composition of a typical desktop PC is complex and consists of hundreds of different materials which may be valuable, precious as well as hazardous in nature. Due to globalization and changing economic scenario, huge amount of E-waste is generated and its management has become a challenging task. The present paper highlights the various metals that can be recovered and recycle from the capacitors obtained from the printed circuit boards (PCB) of Central Processing Unit (CPU). Capacitors contain valuable (Aluminum, iron, copper, zinc, magnesium, manganese, nickel, etc.), hazardous (lead, chromium) and precious (silver) metals. The study of capacitors has been broadly undertaken following various systematic steps, which includes study of different types of capacitors present on the PCBs, its quantification, and characterizations studies. Effect of surface area on metal leaching efficiency was studied. It was observed that the electrolytic capacitors are present in higher quantity followed by solid electrolytic capacitors. Most of the valuable and hazardous metals were found in ceramic, film and solid electrolytic capacitors, also the metal leaching rate enhances by increasing surface area.

Mosquitoes-Insects carry many potentially dangerous diseases like mosquito-borne viral encephalitis, dengue, chicken guinea, yellow fever, malaria, filariasis, etc. and affects around one to three million people globally. To minimize risk and to avoid bites, protective measures practiced includes mosquito coils, repellent mats, vaporizers, aerosol and body cream or lotions etc. But there are certain limitations and draw backs associated with the existing products-systems which includes health implication on users due to uses of chemicals, fire hazards and safety, effectiveness, ease of handling/operation and economy. Moreover, it doesn’t completely destroy the mosquitoes-insects and just keeps them at bay, in order to provide the temporary relief for limited hours in the specified area. More importantly due to the recent outbreak and spread of deadly ZIKA VIRUS in African and American continent due to mosquitoes, it is urgently required to control the mosquitoes’ menace. So, there is a need and market for indigenous, low cost, eco-friendly efficient mosquito controlling device. The patented (3013DEL2015) invention describes a use of developed low cost non-hazardous material in a specially design machine which produces mosquito-insect attractants in more economical and convenient way, which lures the mosquitoes-insects towards the source i.e. machine and gets eventually kill by electric field. The invention targeted to be cost effective for controlling the mosquitoes’ problem without any negative implications on user health or environment.
