This review describes the analytical techniques used to detect DNA-probes such as Ru(II) complexes with hetero cyclic imidazo phenanthroline (IP) ligands. Studies on drug-DNA interactions are useful biochemical techniques for visualization of DNA both in vitro and in vivo. The interactions of small molecules that binds to DNA are mainly classified into two major classes, one involving covalent binding and another non-covalent binding. Covalent binding in DNA can be irreversible and may leads to inhibition of all DNA processes which subsequently leads to cell death. Usually, covalent interactions leads to permanent changes in the structure of nucleic acids. The non-covalent interaction of molecules with DNA can be due to electrostatic interaction, intercalation and groove binding. These interactions of DNA probes can be explored by various spectroscopic techniques viz. UV-visible, emission, emission quenching spectroscopy, viscosity and thermal denaturation measurements.

River is main source of water for drinking and domestic usage. Over exploitation and discharge of surface water in river stream has ecologically stressed the rivers. In view to manage river health, it is essential to carry out river engineering periodically. River follows complex structure; goes through dense forest and valleys. Therefore, measuring water quality and several other parameters associated with the river is a discouraging job. Mostly river follows longest path and generating data for such large geographical area is very challenging. Scientific study of the river requires data for several consecutive years. Having such large data requirement and expecting data generation simply through field-work is highly burdened and never ending process. Therefore, in this paper we introduced auto data generation techniques like: data extraction, data generation through public-partnership, data estimation and data generation using GIS (Geographic information system) based utility software. Lastly, we illustrate complete data generated by using these auto data generation techniques

Trip Time Comparison of Conventional and Exchange Container Mode for Solid Waste Bins Collection: A Case Study of Ilorin Nigeria(Journal of Environmental Science and Engineering)
(A.S. Aremu, Ritesh Vijay O.O. Adeleke,55,1,1-8,Year : 2013)
|
The use of hauled container system for municipal solid waste collection and transportation often results in socio-economic and environmental impacts which are linearly related to trip time. In this study, trip times for the conventional and exchange container mode of solid waste collection by the hauled container system were evaluated. A trip time model was developed for this evaluation through field studies. The model was applied on ten trips to collect solid waste bins and its transportation to disposal site in the city of Ilorin, Nigeria. The results of the model for both modes were compared and Showed that at 5 % significance level,.the trip time for the conventional mode was greater than the trip time for the exchange container mode. Also, the exchange container mode resulted in haul distance reduction by 3 to 15% and trip time reduction by 2.5 to 13 %. This reduction could help in improving logistics and also reduce the negative, impacts associated with collection operation.

Methane emission potential and increased efficiency of a phytoremediation system bioaugmented with bacillus firmus xjsl 1-10(International Journal of Phytoremdiation )
(Prachi A. Nimkar, Niranjan Kolekar,Vol.14(9):,,845-53,Year : 2012)
|
Horizontal subsurface flow constructed wetland mesocosms (HSSCW) designed to treat municipal waste water were bioaugmented with Bacillus firmus XJSL 1-10. The efficiencies of the three HSSCW mesocosms (non-vegetated HSSCW, Schoenoplectus validus HSSCW and Bambusa vulgaris HSSCW) were assessed. Bioaugmentation not only enhanced the efficiency of the phytoremediation system but also reduced methane emission from an average of 51.3 mg/m2/d to 21.6 mg/m2/d in Schoenoplectus validus HSSCW and from an average of 1708 mg/m2/d to 1473 mg/m2/d in Bambusa vulgaris HSSCW. Each of the three types of bioaugmented HSSCWs showed higher purification efficiency with respect to the removal of BOD and NH4-N than the non-bioaugmented HSSCWs. The performance enhancement was most significant in bioaugmented Schoenoplectus validus HSSCW mesocosm with 48.8 and 44.8% lower BOD, and NH4-N, respectively than the non-bioaugmented HSSCW.

Treatment options for wastewater from pharmaceutical companies: a review(The International Journal of Environmental Science and Technology)
(A.M.Deegan, K.Nolan, K.Urell, M. Oelgemoeller, J.Tobin, A.Morrissey,,,649-666 ,Year : 2011)

" In recent years, concerns about the occurrence and fate of active pharmaceutical ingredients, solvents, intermediates and raw materials that could be present in water and wastewater including pharmaceutical industry wastewater has gained increasing attention. Traditional wastewater treatment methods, such as activated sludge, are not sufficient for the complete removal of active pharmaceutical ingredients and other wastewater constituents from these waters. As a result, complementary treatment methods such as membrane filtration, reverse osmosis and activated carbon are often used in conjunction with the traditional methods for treatment of industrial wastewater. Most of the literature published to date has been on the treatment of municipal wastewater. However, there is a growing body of research that looks at the presence of active pharmaceutical ingredients in industrial wastewater, the treatment of these wastewaters and the removal rates. This article, reviews these treatment methods and includes both traditional methods and advanced oxidation processes. The paper concludes by showing that the problem of pharmaceuticals in wastewaters cannot be solved merely by adopting end of pipe measures. At source measures, such as replacement of critical chemicals, reduction in raw material consumption should continue to be pursued as the top priority"

Enhanced arsenic removal from drinking water by iron-enriched aluminosilicate adsorbent prepared from fly ash(Journal of Desalination and Water Treatment)
(,,,,Year : 2016)
|
"The study deals with an efficient approach for the utilization of fly ash and mitigating one of the most severe drinking water problems caused due to arsenate. Iron enriched alumi- nosilicate adsorbent (IEASA) was synthesized using a novel method of alkali fusion of fly ash followed by ageing and hydrothermal curing. The raw material, intermediates, and final products were thoroughly characterized using powder X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy, and particle size analysis. The charac- terization results suggested that the prepared adsorbent is highly crystalline with particle size of 500 nm. The IEASA was evaluated as an adsorbent for the removal of arsenate at initial concentration of 1 mg L, 1 by batch adsorption studies, which shows excellent removal efficiency for arsenate (above 99%) in wide pH range of 4–10 and in the presence of various interfering ions. The efficiency was also compared with synthetic zeolite, which shows negligible arsenate removal. Adsorption isotherms were plotted using the Langmuir and Freundlich models to compute the adsorption capacities. The adsorption capacity obtained from Langmuir isotherm was 0.592 mg g 1as compared to the adsorption capacity of 0.455 mg g 1calculated from kinetics data. Detailed kinetics studies were also carried which confirms that the adsorption kinetics follows pseudo-second-order and particle diffu- sion is the rate determining step. Water quality was evaluated before and after adsorption, which suggests the suitability of the adsorbent for the decontamination of arsenate from drinking water and other parameters also confirms that treated water is potable."

Ceftriaxone is a broad spectrum antibiotic which belongs to the third generation of cephalosporin group. A simple, accurate, precise, reproducible and cost effective one level agar diffusion (5 + 1) bioassay was developed and validated for the estimation of potency and bioactivity of ceftriaxone sodium in pharmaceutical preparations. Among 15 strains of bacteria and 3 strains of fungi, Kocuria rhizophila ATCC-9341 was selected as the most effective organism against ceftriaxone sodium. Optimization of the bioassay was performed by investigating several factors such as buffer pH, inoculums concentration and standard solution concentration. The developed method was successfully validated with respect to linearity, precision and accuracy. The mean potency recovery value for ceftriaxone sodium in commercial dry powder injection of Monocef was 100.44%. An evaluated validation method showed linearity (r2 ¼ 0.986), precision (interday R.S.D ¼ 1.03%, between analyst R.S.D ¼ 1.00%) and accuracy 101.17% (R.S.D ¼ 0.80%). Identification of Monocef was performed by FTIR spectroscopy. The potency of the microbial bioassay was correlated with the HPLC method using the same commercial sample (Monocef). The obtained percent potency was 101.39% by the HPLC method. Results show that the bioassay can be applicable for quantitative determination of the potency with bioactivity in commercial formulations of ceftriaxone sodium.

Treatment of stabilized land all leachate is a great challenge due to its poor biodegradability. Present study made an attempt to treat this wastewater by combining electro-Fenton (E-Fenton) and biological process. E-Fenton treatment was applied prior to biological process to enhance the biodegradability of leachate, which will be bene?cial for the subsequent biological process. This study also investigates the ef?ciency of iron molybdophosphate (FeMoPO) nanoparticles as a heterogeneous catalyst in E-Fenton process. The effects of initial pH, catalyst dosage, applied voltage and electrode spacing on Chemical Oxygen Demand (COD) removal ef?ciency were analyzed to determine the optimum conditions. Heterogeneous E-Fenton process gave 82% COD removal at pH 2, catalyst dosage of 50 mg/L, voltage 5 V, electrode spacing 3 cm and electrode area 25 cm 2 . Combined E-Fenton and biological treatment resulted an overall COD removal of 97%, bringing down the ?nal COD to 192 mg/L.

How the Atmosphere over Eastern Himalaya, India is Polluted with Carbonyl Compounds? Temporal Variability and Identification of Sources(Aerosol and Air Quality Research)
(,,,,Year : 2017)
|
A study was conducted on atmospheric carbonyl compounds for the first time over a Himalayan atmosphere in India. Samples were collected from a high altitude hill station, Darjeeling (27.01°N, 88.15°E, 2200 masl) during June 2012 to May 2013. Temporal variation, meteorological influence, source apportionment and ozone formation potential etc were studied for acetaldehyde, formaldehyde, acetone, butanaldehyde, propanaldehyde, benzaldehyde, crotonaldehyde, valeraldehyde, isovaleraldehyde, hexanaldehyde, p-tolualdehyde and o-tolualdehyde. High concentration of Acetone (81.6 ± 63.5 μg m–3) was observed which could be due to the higher photochemical production from its precursor volatile organic compounds emitted from tea plants and tea processing units. The concentration of acetaldehyde (20.7 ± 47.6 μg m–3) and formaldehyde (11.6 ± 16.3 μg m–3) were found to be comparable with metro cities of India and world. The average annual concentration of total carbonyl compounds was 174.2 ± 184.6 μg m–3 with maximum during postmonsoon (456.9 ± 199.5 μg m–3) and minimum during winter season (72.2 ± 42.9 μg m–3). Meteorological parameters like temperature and surface reaching solar radiative flux played the major roles for the seasonal variation of the carbonyl concentration over the hill station. The average ratio of formaldehyde to acetaldehyde over Darjeeling was found to be 1.64 ± 1.43 well representing a typical urban atmosphere at this part of Himalaya. Positive matrix factorization model showed that the biogenic emissions from tea plants and vehicular emissions were the major sources of carbonyl compounds over the hill station.

Geospatial assessment of tourism impact on land environment of Dehradun, Uttarakhand, India(Environmental Monitoring and Assessment)
(Jaydip Dey,S. Sakhre, V. Gupta, Ritesh Vijay, Sunil Pathak, Rajesh Biniwale, Rakesh Kumar,190,4,181,Year : 2018)

India’s tourism industry has emerged as a leading industry with a potential to grow further in the next few decades. Dehradun, one of the famous tourist places in India located in the state of Uttarakhand, attracts tourist from all over the country and abroad. The surge in tourist number paved the way for new infrastructure projects like roads, buildings, and hotels, which in turn affects the topography of the mountainous region. In this study, remote sensing and GIS techniques have been used to assess the impact of tourism on the land environment of Dehradun. Satellite images of the years 1972, 2000, and 2016 were analyzed using objectbased image analysis (OBIA) to derive land use and land cover (LULC) and ASTER-DEM (Digital Elevation Model) was used to determine the topography of the study area. LULC classification includes built-up, vegetation, forest, scrub, agriculture, plantation, and water body. The slope of the region was categorized as gentle, moderate, strong, extreme, steep, and very steep. To assess the sprawl of built-up on high terrain land, built-up class of LULC was overlaid on slope classes. The overlay analysis reveals that due to increase in tourism, the land use in terms of the built-up area has been extended from gentle slope to very steep slope. The haphazard construction on the extreme, steep, and very steep slope is prone to landslide and other natural disasters. For this, landslide susceptibility maps have also been generated using multicriteria evaluation (MCE) techniques to prevent haphazard construction and to assist in further planning of Dehradun City. This study suggests that a proper developmental plan of the city is essential which follows the principles of optimum use of land and sustainable tourism.
