Subject: Toxic aqueous discharge of iron and sulphur from spoiled coal mined lands and its control by phytostabilization process
Keywords: Acid mine drainage, coal mining, northeastern India, phytostabiliza
Abstract: Toxic aqueous discharge of iron and sulphur due to acid mine drainage causes soil and water pollution. Many countries with unoperating as well as functional
mining industries face this problem. In north-eastern India, coal mining has severely degraded much of the
agricultural land by impairing soil, plant diversity and water quality. A study was conducted in coal mined out area of Jaintia hills, Meghalaya (northeastern India) to eliminate toxic aqueous discharge
(iron and sulphur) and restore the soil fertility of affected land for sustainable crop production. The treatment of acid mine drainage through phytostabilization and soil amendment with agricultural lime and
organic manures reduced sulphate from 22 to 5 mg kg–1 and soluble iron from 476 to 109 mg kg–1 of surface soil. The soil pH increased by 1.4 unit from its initial value and concentration of plant nutrients like
N, P, K and microbial biomass content reached optimum fertility levels. Soluble iron and sulphate in drainage water reduced considerably by 26% and
49% respectively, with concurrent increases in water pH (3.2 to 7.2). Rice grain yield in the mined-out area reached about 1320 kg ha–1 after reclamation as compared 1920 kg ha–1 in non-mined area. The adaptation
of native plant species (Citrus reticulate, Prunus napalensis and Pyrus communis) was about 70%. Afforestation with native fruit plant species and ferns/
grasses, soil amendment using lime and organic manure, and channelling of seepage water for checking acid mine drainage contamination of water bodies
and crop fields were some of the measures that were effective in mitigating toxicity. Phytostabilization helped in reversing the trend and restoring soil fertility and plant growth due to a rise in soil organic matter, nutrient availability as well as biological activities.

Subject: Changes in water stability of soil aggregates in a solar greenhouse in different planted years and their relationship to iron oxide
Keywords: Iron oxide, soil aggregate, soil cementation process, solar greenhouse, water stability.
Abstract: The distribution and stability of soil aggregates and its relation to iron oxide during different plantation years
are studied in a solar greenhouse. Soil samples were obtained from a vetatable bed within a greenhouse in Xinmin (Liaoning, China). The composition, water
stability and percentage of aggregate destruction, as well as variations in different forms of iron oxides were evaluated at 5 time points (0, 2, 5, 8 and 16 years). Soil from a dry land in an open field was also
collected for comparison. The quantity and water stability of >0.25 mm soil aggregates from 2 and 5 years were lower than those in the soil from the open field. These parameters significantly increased after five
years. The contents of non-free iron oxides decreased under greenhouse cultivation, resulting in reduced aggregate stability. Free iron oxides were positively associated with >2 mm aggregates. Complex iron
oxides were positively correlated with 2–0.25 mm and 0.25–0.053 mm aggregates but negatively correlated with <0.053 mm aggregates.

Subject: Bt-cotton–vegetable-based intercropping systems as influenced by crop establishment method and planting geometry of Bt-cotton in Indo-Gangetic plains region
Keywords: Bt-cotton, crop establishment methods, intercropping systems, planting geometry, vegetable cow
Abstract: The present study was conducted at ICAR-Indian Agricultural Research Institute, New Delhi in a split plot design replicated thrice with four main-plot treatments, i.e., four combinations of two cotton establishment methods (CEMs) and two planting geometries (PGMs) [M1 – transplanted cotton (90 × 60 cm PGM); M2 – transplanted cotton (120 × 45 cm PGM);
M3 – direct seeded cotton (DSC; 90 × 60 cm PGM); M4 – DSC (120 × 45 cm PGM)]; while sub-plot treatments comprised three intercropping systems [S-Ct – sole cotton; Ct + Ok – cotton + okra (1: 2 row ratio);
Ct + Cp – cotton + cowpea (vegetable purpose; 1: 2 row ratio)]. It can be inferred from the study that transplanted cotton (TPC) with 90 × 60 cm planting geometry in Bt-cotton + vegetable cowpea intercropping system exhibited maximum seed-cotton equivalent yield (SCEY) as well as gross and net returns and other economic indices, followed by Ct + Ok and sole cotton. DSC with 90 × 60 cm PGM in Ct + Ok intercropping system proved superior in terms of SCEY, and gross and net returns besides other economic indices. Based upon yield advantage indices, TPC in
90 × 60 cm PGM under Ct+Cp intercropping system and DSC in 90 × 60 cm PGM under both intercrops were found to be the best options. Crop competition indices also revealed that the inclusion of these intercrops is advantageous because of spatial and temporal complementarity, different rooting pattern and plant
architecture to utilize natural resources more efficiently in Bt-cotton-based intercropping systems in the semiarid Indo-Gangetic plains region.

Subject: Forest cover monitoring and prediction in a Lesser Himalayan elephant landscape
Keywords: Change detection, deforestation, elephant landscape, Northeast India, satellite images.
Abstract: We have monitored the forest cover depletion in parts of Assam and Arunachal Pradesh over an area of
42,375 km2 in an elephant landscape falling in the Lesser Himalaya, North East India and report the results here. The US Army topographic maps (1924) and
multi-date satellite images (1975, 1990, 2000 and 2009) were visually interpreted on-screen for post-classification comparison and forest cover change detection. The exercise showed continuous high loss of forest cover during the study period. A land area having 17,846.27 km2 forest in 1924 was depleted to 12,514.56 km2 by 1975, 11,861.75 km2 by 1990, 10,808.92 km2
by 2000 and 10,256.58 km2
by 2009, thereby indicating a constant decrease in forest cover by 12.59%, 1.54%, 2.48% and 1.31% respectively.
The total loss in forest cover was estimated to be about 7590 km2 from 1924 to 2009. The Cellular Automata Markov Model has predicted a further likely decrease of 9007.14 km2 by 2028. In general, more districts of Assam than Arunachal Pradesh and more plains than hills faced deforestation. We have identified increasing human population and subsequent demand on the land for cultivation as major reasons for forest cover depletion.

Subject: Optimization of factors affecting decolourization of sulphonated azo dye Red HE7B in vitro by Bacillus sp. Azo1
Keywords: Azo dye, Bacillus sp., co-substrate, decolourization
Abstract: Azo dyes are widely used organic molecules that are generally recalcitrant to biodegradation, thus causing environmental pollution. In this study, the effect of
various growth conditions like temperature, pH, dye concentration, aeration and presence/absence of co-substrate on decolourization of azo dye Red HE7B
by Bacillus sp. Azo1 has been determined. Decolorization of the dye was achieved under static condition. Optimum decolourization of Red HE7B was observed
at 30°C and 50 mg/l dye concentration, where more than 90% decolourization was achieved within three days of inoculation. Bacillus sp. Azo1 could decolorize the dye through a range of pH values from 6 to 9.
Presence of co-substrate limited the decolourization with glucose being the most potential inhibitor. Identification of factors influencing decolourization will
help in rapid removal of these pollutants from contaminated habitat.

Subject: Soil quality and fibrous mineral in black soils of Maharashtra
Keywords: Fibrous minerals, palygorskite, black soils, soil quality
Abstract: There are many reports on soil parameters that have both yield-reducing and yield-favouring potential. However, only a few are available on the index soil properties of fibrous minerals containing soils on crop
yields in the semi-arid tropical (SAT) regions. These minerals in soils are mostly palygorskite and sepiolite. In the present study, only the palygorskite mineral in
black soils (cracking clay soils), its formation and probable influence on soil quality is addressed. The present study was also undertaken to indicate a possible genesis of palygorskite in Indian black soils with
and without soil modifiers (Ca-zeolites and gypsum) supporting both rainfed and irrigated agriculture in SAT environments. Palygorskite is absent in ridic/gypsic/sodic intergrades of black soils (Haplusterts),
which might indicate non-interference of soil modifiers in its formation. Palygorskite is present only in sodic black soils (Calciusterts) in Maharashtra and
parts of central and western India that contain no soil modifiers and are under both rainfed and irrigated agricultural systems. The severe impairment of hydraulic properties of palygorskite containing naturally degraded black soils warrants a new research initiative for soils containing fibrous minerals.

Keywords: Antibacterial activity, chalcone oxime, metal complex, mole ratio.
Abstract: In this study, microwave-assisted green synthesis of a complex of Ni (II)-2′,4′-dihydroxy 4-fluoro chalcone oxime has been carried out. The structure of the complex was characterized by elemental analysis, molar conductance, magnetic moment, IR, 1 H-NMR, 13CNMR spectroscopic data and thermal studies. IR data showed that Ni (II) is coordinated to the ligand through the phenolic-O and azomethine-N of the latter. TGA studies confirmed the presence of coordinated
water molecules. The 1 : 2 metal to ligands stoichiometry was indicated by mole ratio method, which was further confirmed by Job’s method of continuous variation modified by Turner and Anderson. Stability
constant (Ks) of the complex determined by mole ratio method was 8.5245. Standard free energy change (ΔG0) for metal–ligand complex formation was found
to be –11.7026 K cal/mol at 27 ± 2°C. On the basis of analytical data, octahedral structure has been proposed for the complex. All compounds were tested for
antibacterial activity and showed moderate to good activity against Escherichia coli and Staphylococcus aureus at different concentrations. In this study, we report synthesis of oxime derivative of chalcone and its Ni (II) complex in the hope of developing new compounds which might be used as analytical reagents or
intermediates in the synthesis of various classes of bioactive compounds.

Subject: Experimental study on the hydraulic fracture propagation in shale
Keywords: Fracture propagation, fracture network, hydraulic fracturing, shale, stimulated reservoir volume
Abstract: To realize the control on geometry of fracture network and improve the individual well production of shale gas reservoirs, hydraulic fracturing simulation tests of shale outcrops for horizontal well were carried
out. This was based on an established true triaxial hydraulic fracturing simulation test system, to analyses the propagation and formation of a complex fracture network. The results show that the typical severe
fluctuation of pump pressure during extension, is an obvious feature of hydraulic fracturing by Stimulated Reservoir Volume (SRV). Due to the large size and abundant natural fractures in shale specimens, the
acoustic emission (AE) energy is weak during propagation of hydraulic fractures. However, fracture propagation can still be effectively determined to some extent,
although relatively few AE events are detected. Hydraulic fractures from horizontal well initiate approximately along the maximal in situ stress. But the fractures gradually deviate from the orientation when
extending. Branching, re-orientation or penetrating bedding planes and then interconnecting with natural fractures or weak beddings are the main mechanisms
of the formation of complicated fracture networks.

Subject: onomic dispatch problem
Keywords: Artificial memory, benchmark function, economic dispatch, KMTOA
Abstract: Economic dispatch (ED) problem exhibits highly nonlinear characteristics, such as prohibited operating zone, ramp rate limits and non-smooth property. Due to its nonlinear characteristics, it is hard to achieve the expected solution by classical methods. To overcome the challenging difficulty, an improved optimization algorithm based on kinetic-molecular theory (KMTOA) was proposed to solve the ED problem in this article. Memory principle is employed into the improved algorithm. By accepting strengthened or weakened stimulus strength, the memory is divided into four states; instant-term, short-term, long-term and forgotten states to update the memory value iteratively. In this way, more and more elites appear in the long-term memory library. Simultaneously, the improved KMTOA, according to the elite population-based guide on the other population, enhances the search ability and avoids the premature convergence which
usually suffered in traditional KMTOA. The designs are able to enhance the performance of KMTOA, which has been demonstrated on 12 benchmark functions. To validate the proposed algorithm, we also use three different systems to demonstrate its efficiency and feasibility in solving the ED problem. The experimental results show that the improved KMTOA can achieve higher quality solutions in ED problems.

Abstract: Collaboration has strongly intensified recently and its characteristics are attractive and multidimensional. This study explored the trends, characteristics and citation impact of collaboration as well as collaboration networks for the macrolevel of country, the mesolevel of institution and the microlevel of author, using highly cited articles in environmental engineering (EE) category of the Science Citation Index Expanded. A data visualization and manipulation software, Gephi 0.9.1 was
used to visualize the relationships of collaboration among authors, institutions and countries. Although collaboration in general is known to be beneficial in many research areas, collaboration
is not beneficial for highly cited research in the EE field. Single author, single country and single institution articles were more visible than articles involving international collaboration, interinstitutional collaboration and individual collaboration. There were certain group collaborations,
which played an important role in publishing highly cited articles in the EE field.

Keywords: Reactivation of minor scars to major landslides – a satellite-based analysis of Kotropi landslide (13 August 2017) in Himachal Pradesh, India
Abstract: On 13 August 2017, a massive landslide
occurred close to the village of Kotropi
(near Kotropi bus stop) in Mandi district,
Himachal Pradesh, India. It occurred on
National Highway 154, the road between
Mandi and Pathankot. Media reports
suggest that a section of the slope totally
collapsed and two buses of the Himachal
State Transport Corporation along with
few other vehicles were buried under the
debris. News reports also suggest that
there have been 46 fatalities from the
incident. Around 300 m of the highway
has been completely buried under debris,
thus, disrupting communication on an
important route

Subject: Do extreme precipitation intensities linked to temperature over India follow the Clausius–Clapeyron relationship?
Keywords: extreme precipitation, Clausius–Clapeyron relationship
Abstract: Recent Intergovernmental Panel on
Climate Change (IPCC) reports suggest
that the atmosphere is getting warmer in
almost every region across the globe. As
a consequence, extreme precipitation intensities (EPIs) are increasing in many
regions according to the principle of
Clausius–Clapeyron (CC) relationship,
which states that atmospheric moisture
storage capacity increases by ~7% per degree rise in temperature
. Therefore, the frequency of extreme precipitation events may increase with societal impacts on agriculture, economy, human health and animal habitats.

Subject: CO2 emissions – drivers across time and countries
Keywords: CO2 emissions, drivers across time and countries
Abstract: Carbon dioxide (CO2) emissions from fossil fuels are the most important cause of global warming. Here we analyse recent data published by the International Energy Agency. CO2 emission drivers like population, GDP, carbon intensity and energy efficiency are analysed for the time period from 1971 to 2015 for the
whole world and five countries like USA, Japan, Germany, China and India. Carbon intensity of primary energy supply has not changed much, but population and GDP have increased sharply. Energy efficiency,
including structural changes in economy have restricted CO2 emissions to some extent, but continuous increase of GDP by developed countries will not leave much space for growth of developing countries.
Emissions from road transport and residential sectors deserve special attention.
