TL;DR: In this paper, the relativistic mean field plus state-dependent BCS approach (RMF+BCS) was employed to study the ground state properties of selected even-Z nuclei in the region 20 ≤ Z ≤ 40.
Abstract: Inspired by recent experimental studies of two-proton radioactivity in the light-medium mass region, we have employed relativistic mean-field plus state-dependent BCS approach (RMF+BCS) to study the ground state properties of selected even-Z nuclei in the region 20 ≤ Z ≤ 40. It is found that the effective potential barrier provided by the Coulomb interaction and that due to centrifugal force may cause a long delay in the decay of some of the nuclei even with small negative proton separation energy. This may cause the existence of proton-rich nuclei beyond the proton drip-line. Nuclei 38Ti, 42Cr, 45Fe, 48Ni, 55Zn, 60Ge, 63, 64Se, 68Kr, 72Sr and 76Zr are found to be the potential candidates for exhibiting two-proton radioactivity in the region 20 ≤ Z ≤ 40. The reliability of these predictions is further strengthened by the agreement of the calculated results for the ground state properties such as binding energy, one- and two-proton separation energy, proton and neutron radii, and deformation with the available experimental data for the entire chain of the isotopes of the nuclei in the region 20 ≤ Z ≤ 40.

TL;DR: In this article, the authors analyzed changes in the LST and UHI phenomena for Jaipur city over the period from 2000 to 2011 and analyzes the spatial distribution and temporal variation of LST in context of changes in LULC.
Abstract: . Urban Heat Island (UHI) refers to the phenomena of higher surface temperature occurring in urban areas as compared to the surrounding countryside attributable to urbanization. Spatio-temporal changes in UHI can be quantified through Land Surface Temperature (LST) derived from satellite imageries. Spatial variations in LST occur due to complexity of land surface – combination of impervious surface materials, vegetation, exposed soils as well as water surfaces. Jaipur city has observed rapid urbanization over the last decade. Due to rising population pressure the city has expanded considerably in areal extent and has also observed substantial land use/land cover (LULC) changes. The paper aims to determine changes in the LST and UHI phenomena for Jaipur city over the period from 2000 to 2011 and analyzes the spatial distribution and temporal variation of LST in context of changes in LULC. Landsat 7 ETM+ (2000) and Landsat 5 TM (2011) images of summer season have been used. Results reveal that Jaipur city has witnessed considerable growth in built up area at the cost of greener patches over the last decade, which has had clear impact on variation in LST. There has been an average rise of 2.99 °C in overall summer temperature. New suburbs of the city record 2° to 4 °C increase in LST. LST change is inversely related to change in vegetation cover and positively related to extent of built up area. The study concludes that UHI of Jaipur city has intensified and extended over new areas.

TL;DR: For the characterization of heavy metals of various industrial effluents, some heavy metals, like Arsenic, Cadmium, Chromium, Copper, Iron, Manganese, Nickel, Lead and Zinc were analyzed and exhibited that As, Cd, Cr and Pb were not found in any studied wastewater samples, while some of the following heavy metals ranged from.
Abstract: Heavy metals contamination has been recognized as a major environmental concern due to their pervasiveness and persistence. These heavy metals are not biodegradable, hence there is a need to develop such a remediation technique, which should be efficient, economical and rapidly deployable in a wide range of physical settings. For the characterization of heavy metals of various industrial effluents, some heavy metals, like Arsenic, Cadmium, Chromium, Copper, Iron, Manganese, Nickel, Lead and Zinc were analyzed. The results exhibited that As, Cd, Cr and Pb were not found in any studied wastewater samples, while some of the following heavy metals ranged from: Cu (0.0 - 1.0 mg/L), Fe (0.1 - 0.4 mg/L), Mn (0.0 - 0.4 mg/L), Ni (0.01 - 0.07 mg/L) and Zn (0.68 - 60.84 mg/L). Copper, Iron, Manganese and Zinc were found above the standard limit recommended by IS: 3307 (1977). However, Nickel was found below the regulated safety values for all studied samples.

TL;DR: In this paper, a bismuth iron oxide-graphene composite has been explored as electrode material for electrochemical supercapacitor application, and the specific capacitance of the composite electrode measured at 5-100mV/s was found to be 17-4mF/cm2 which is comparable to the most commonly used metal oxide based electrode materials.
Abstract: In the present work, bismuth iron oxide–graphene composite has been explored as electrode material for electrochemical supercapacitor application. Bismuth iron oxide (BFO) nanoparticles, synthesized by sol–gel process, are mixed with the graphene sheets in a solution. The electrodes are prepared by coating the resulted slurry on stainless steel (SS) substrate, by drop casting process. The morphology and structure of the BFO–graphene composite are characterized by XRD, FIB-SEM, HRTEM and Raman spectroscopy, which show that the nanoparticles with diameter 100–200 nm are randomly distributed on and around the graphene sheets. The composite electrode exhibits significantly enhanced capacitance as compared to BFO. In this structure, the electrons generated by the surface based Faradaic reactions from the BFO nanoparticles can be transported by the graphene nanosheets toward the current collector. The electrochemical characteristic of the electrodes is investigated through cyclic voltammetry and charging/discharging process. The specific capacitance of the electrode measured at 5–100 mV/s was found to be 17–4 mF/cm2 which is comparable to the most commonly used metal oxide based electrode materials. It shows better cycling stability with 95% retention of capacitance after 2000 cycles.

TL;DR: In this paper, the effect of the event shape selection on the elliptic flow coefficient v2 was investigated for Pb-Pb collisions at √sNN=2.76 TeV.
Abstract: We report on results obtained with the event-shape engineering technique applied to Pb-Pb collisions at √sNN=2.76 TeV. By selecting events in the same centrality interval, but with very different average flow, different initial-state conditions can be studied. We find the effect of the event-shape selection on the elliptic flow coefficient v2 to be almost independent of transverse momentum pT, which is as expected if this effect is attributable to fluctuations in the initial geometry of the system. Charged-hadron, -pion, -kaon, and -proton transverse momentum distributions are found to be harder in events with higher-than-average elliptic flow, indicating an interplay between radial and elliptic flow.
