Tilpara barrage over Mayurakshi River has exerted crucial impact on backwater reach of river Kushkarni (4.5 km upstream reach) which debouches to Mayurakshi River at immediate upstream head of this barrage. Study area is located at the Chota Nagpur plateau fringe highly erodible Rarh tract of Birbhum district of West Bengal. From this study, it is found that due to storage of water in the reservoir, backwater created and confluence part of the Kushkarni River is submerged. Stagnation of reservoir water reduced carrying capacity of channel by 26 %, and it is facilitated by declining trend of channel bed slope and velocity of flow. Depth of channel is attenuated by 17–71 cm depositing 919,342.6 m3 of coarser sediment load. In this circumstance, high flood level frequency in same inflow state has increased by 26.5 % and channel braiding has started to nucleate. Alternate textural sequence of materials from river bed reveals some irregular episodic inflow events within reservoir. Episodic discharge and consequent large flood have created thick sand splay cover in the left side of the channel and damaged agricultural land. Potential bank erosion hazard index or BEHI is considerably high (27.35–31.73) in this backwater reach, and the process is mainly triggered by liquefaction. Considering existing forms and functions of the study segment, it is evaluated with existing reservoir upstream channel morphology model of Skalak et al. (2013) and found to be proximate. Such alteration of channel morphology in this segment is linked with socio-ecological fabric of the surrounding area. Along with channel morphological readjustment, socio-ecological setup is also moving toward new adjustment. © 2016 Springer Science+Business Media Dordrecht

An investigation of the hydromagnetic boundary layer flow past a moving vertical plate in nanofluids in the presence of a uniform transverse magnetic field and thermal radiation has been carried out. Three different types of water-based nanofluids containing copper, aluminum oxide and titanium dioxide are taken into consideration. The governing equations are solved using Laplace transform technique and the solutions are presented in closed form. The numerical values of nanofluid temperature, velocity, the rate of heat transfer and the shear stress at the plate are presented graphically for several values of the pertinent parameters. The present study finds applications in engineering devices. © 2014 Elsevier B.V. All rights reserved.

Malaria, a mosquito-borne disease, is caused by the infection of apicomplexan parasites belonging to the genus Plasmodium, five species of which [Plasmodium vivax, Plasmodium falciparum (P. falciparum), Plasmodium ovale, Plasmodium malariae and Plasmodium knowlesi] account for all forms of human malaria. P. falciparum is responsible for the highest degree of complications (severe malarial anaemia and cerebral malaria) and mortality in the tropics and subtropics of the world. Despite the large burden of vivax malaria, it is overlooked and left in the shadow of severity of falciparum malaria in the globe, but current reports provide evidence of severe vivax malaria symptoms similar to P. falciparum infection. The major challenging factor is the emergence of multidrug resistant Plasmodium strains to the conventionally used antimalarials over the last two decades, and, more recently, to artemisinins. The WHO recommended artemisinin based combination therapies (ACTs). The non-ACT regimens are also found to be effective, safe, and affordable compared to ACTs. However, current successful antimalarial interventions are under threat from the ability of the parasite and its mosquito vector to develop resistance to medicines and insecticides, respectively. Hence, with widespread use of effective drugs and vector control with insecticide-treated bed nets and indoor residual spraying, an ideal malaria vaccine would be the actual means of malaria prevention. This review represents the current evidence, based upon the search of SCI-and non-SCI journal, on epidemiological aspects of two forms (vivax and falciparum) of human malaria, which is still a great global concern. © 2014 Asian Pacific Tropical Medicine Press.

Ground state energies of exotic three-body atomic systems consisting two muons and a positively charged nucleus like: 1H+μ -μ -, 4He 2+μ -μ -, 3He 2+μ -μ -, 7Li 3+μ -μ -, 6Li 3+μ -μ -, 9Be 4+μ -μ -, 12C 6+μ-μ-, 16O 8+μ-μ-, 20Ne 10+μ-μ-, 28Si 14+μ-μ- and 40Ar 18+μ-μ-have been calculated using hyperspherical harmonics expansion (HHE) method. Calculation of matrix elements of two body interactions involved in the HHE method for a three body system is greatly simplified by expanding the bra-and ket-vector states in the hyperspherical harmonics basis states appropriate for the partition corresponding to the interacting pair. This involves the Raynal-Revai coefficients (RRC), which are the transformation coefficients between the hyperspherical harmonics bases corresponding to the two partitions. Use of these coefficients found to be very useful for the numerical solution of three-body Schrödinger equation where the two-body potentials are other than Coulomb or harmonic oscillator type. However, in this work the interaction potentials involved are purely Coulomb. The calculated energies have been compared with (i) those obtained by straight forward manner; and (ii) with those found in the literature (wherever available). The calculated binding energies agree within the computational error. © EDP Sciences, Società Italiana di Fisica, Springer-Verlag 2012.

Ground state energies of atomic three-body systems like negatively charged hydrogen, normal helium, positively charged-lithium, beryllium, carbon, oxygen, neon and negatively charged exotic-muonium and positronium atoms have been calculated adopting hyperspherical harmonics expansion method. Calculation of matrix elements of two body interactions needed in the hyperspherical harmonics expansion method for a three body system is greatly simplified by expanding the bra-and ket-vector states in the hyperspherical harmonics (HH) basis states appropriate for the partition corresponding to the interacting pair. This involves the Raynal-Revai coefficients (RRC), which are the transformation coefficients between the HH bases corresponding to the two partitions. Use of RRC become particularly essential for the numerical solution of three-body Schro{double acute}dinger equation where the two-body potentials are other than Coulomb or harmonic. However in the present work the technique is used for two electron atoms 1H -(p +e -e -), D -(d +e -e -), Mu -(μ +e -e -), 4He( 4He 2+e -e -), 6Li( 6Li 3+e -e -), 10Be( 10Be 4+e -e -), 12C( 12C 6+e -e -), 16O( 16O 8+e -e -) etc. and the exotic positronium negative ion Ps -(e +e -e -) where the interactions are purely Coulomb. The relative convergence in ground state binding energy with increasing K max for 20Ne has been demonstrated as a representative case. The calculated energies at K max = 28 using RRC's have been compared with those obtained by a straight forward manner in some representative cases to demonstrate the appropriateness of the use of RRC. The extrapolated energies have also been compared with those found in the literature. The calculated binding energies agree within the computational error. © 2011 Springer-Verlag.

Coriandrum sativum L. (C. sativum) is one of the most useful essential oil bearing spices as well as medicinal plants, belonging to the family Umbelliferae/Apiaceae. The leaves and seeds of the plant are widely used in folk medicine in addition to its use as a seasoning in food preparation. The C. sativum essential oil and extracts possess promising antibacterial, antifungal and anti-oxidative activities as various chemical components in different parts of the plant, which thus play a great role in maintaining the shelf-life of foods by preventing their spoilage. This edible plant is non-toxic to humans, and the C. sativum essential oil is thus used in different ways, viz., in foods (like flavouring and preservatives) and in pharmaceutical products (therapeutic action) as well as in perfumes (fragancias and lotions). The current updates on the usefulness of the plant C. sativum are due to scientific research published in different web-based journals. © 2015 Hainan Medical University.

Massanjore reservoir (area ~67 km2)located 84 km downstream from the most distant upstream source capacitates 620,000,000 m3 of water, and regulated flow characters are highly responsible for dam downstream alteration of hydrological, sedimentological and geomorphological characteristics of Mayurakshi River. In dam after condition, monsoon water level (mean water level during monsoon months) and pre-monsoon water level (mean water level during pre-monsoon months, i.e., March–May) have attenuated about 0.56 and 0.32 m, respectively. Maximum duration of high flow period during monsoon has reduced up to 16.5 %; coefficient of variation of diurnal fluctuation of water level during monsoon has increased from 31 to 47 %. Suspended sediment load in Mayurakshi River is reduced to 34 % in dam after period as recorded at Narayanpur gauge station. Average suspended sediment load has decreased even after Tilpara barrage construction from 4.960 to 4.350 mg/L. Average suspended sediment load is 7.875 mg/L in the sites of dam upstream course, and this average is only 4.46 mg/L in different sites of dam downstream course. Volume of discharge has decreased up to 11.3 % during monsoon time in dam after condition. Such reduction in discharge volume in turn has reduced about 24.6 % bed load-carrying capacity. As a result, huge deposition within channel invigorated channel bed aggradations (average 73.6 cm up to Saspara, site 14 at Fig. 1) in dam after condition. Narrowing of active channel, coarsening of channel bed materials, lowering of lateral stability, accelerating rise of braiding index, mixed response of the channel adjustment of the tributaries to local scale positive or negative base level change due to river bed aggradations and degradation, etc. signify the morphological alteration of dam downstream course.[Figure not available: see fulltext.] © 2015 Springer Science+Business Media Dordrecht

Hydrological alteration plays a crucial role in regulating a hydro-ecological and socio-economic framework. Apart from climate change issue and its impact on flow alteration, human interventions have brought a new paradigm on hydrological regime. The Atreyee river (390 km long) of Indo-Bangladesh is highly affected by the construction of reservoir at Mohanpur of Bangladesh. The present paper concentrates on regulating flow through the reservoir construction and its possible impacts on downstream courses at different hierarchical scales such as alteration of the dynamics of peak flow, monthly flow, average flow, minimum flow, seasonal flow, instability of flow and diurnal flow. Result shows that (1) the discharge ratio of maximum discharge from the reservoir after construction has reduced 4.15–5.66 times in the Atreyee river. (2) After the construction of the reservoir, on an average 53% discharge has curtailed down. On a seasonal scale, total run-off reduction rates are 30.97%, 66.86% and 64.01% during pre-monsoon, monsoon and post-monsoon periods. (3) Post-reservoir condition peakiness of average and maximum monthly water flow has reduced and flow variation (calculated CV) has also reduced by 4.5 and 10 times, respectively. (4) Volume of base flow has attenuated by 18.26% (26.34–21.53 cumec). (5) Percentages of discharge reduction in reservoir after condition are 30.97%, 66.86% and 64.01%, respectively, during pre-monsoon, monsoon and post-monsoon seasons. (6) Modal discharge during pre-monsoon, monsoon and post-monsoon has reduced by 13.38%, 80.31% and 72.20%, respectively. (7) Diurnal range of flow, flow volume, instantaneous flow pulses and mean up and down-ramp rates have reduced in the post-reservoir period. (8) In the post-reservoir period, flow magnitude is so lowered that it cannot maintain the natural threshold limits of flow for sustaining normal environmental performances. © 2016 International Association for Hydro-Environment Engineering and Research
