In this study, the simultaneous determination of Co, Cd, Ni, Cu, and Pb was carried out as a color complex with 4-(2-pyridylazo) resorcinol in an aqueous solution under the assesting of machine learning. A partial least-squares multivariate linear regression and artificial neuron network for the analysis of mixtures of metals were developed. MATLAB is a powerful software machine learning program that was used to support matrix calculations and displays.

To describe nurses’ preferences for the design of a probability-based clinical decision support (PB-CDS) tool for in-hospital clinical deterioration. Methods: A convenience sample of bedside nurses, charge nurses, and rapid response nurses (n ¼ 20) from adult and pediatric hospitals completed participatory design sessions with researchers in a simulation laboratory to elicit preferred design considerations for a PB-CDS tool.

Understanding the financial performance of an engineered system is a key step to its commercialization. In this study, the economic performance of the Mk1 PB-FHR using a nuclear air combined cycle to produce base load nuclear power, and highly efficient peaking power with gas co-firing, was estimated for a regulated electricity market structure.

In this paper, new energy harvesting-based transmission schemes are proposed to improve the outage probability and throughput in underlay cognitive radio networks. In this system, a secondary source can harvest energy from a power beacon (PB) and/or a primary transmitter (PT) to transmit data to a secondary destination in the presence of a primary receiver.

The Hellenic subduction system governs the entire Aegean region through the creation of a migrating magmatic arc that has existed since the beginning of the Early Cenozoic. The Karadağ Pluton is situated in the NW part of Turkey and represents one of the distinct snapshots of this subduction system during the Late Oligocene-Early Miocene Period.iod. It consists of 2 major lithological units, based on their petrographic and geochemical features, comprising: 1) main plutonic facies (SiO2 < 70 wt.

The geochemical behavior of Pb in terrestrial and coastal water systems significantly influences Pb biogeochemical cycling and pollutant exchange at the land-sea continuum. An ideal case study of Pb environmental geochemistry is Galveston Bay, an anthropogenic estuary exposed to industrial runoff, wastewater and shipping vessel spills but also fed by natural rivers.

This paper studies the effects of the sintering temperature on crystal structure, critical temperature (Tc) and excess conductivity of Bi-Pb-Sr-Ca-Cu-O (BPSCCO) system. Bulk BPSCCO samples were fabricated by the solid-state reaction method. Four different temperatures of 835 °C, 840 °C, 845 °C, and 850 °C were applied to sinter four different samples.

Domestic water system of Thai Nguyen city originates from Nui Coc lake which has an area of 25km2 . In fact, due to these original areas that have many metal mines, such as tin, lead, zinc, vonfram,..., the content of heavy metal in the water resource raises need for concern. Therefore, we evaluated the content of some elements: Cr, Mn, Cu, Cd, Pb, Hg in the water resource of Nui Coc lake, Tich Luong lake and the domestic water system of Thai Nguyen city to compare with the Vietnamese standard of maximum acceptable heavy metal content in drinking water.

. In this study, the VEGF121 gene was cloned and expressed in a prokaryotic expression system (Escherichia coli). The recombinant VEGF121 was encapsulated with PLA microparticles and studied in vitro and ex ovo for the sustained release mechanism. The PLA-VEGF microparticles and the recombinant VEGF121 were explored for their bioactivity in human umbilical vein endothelial cells (HUVEC).

A field experiment was conducted during two consecutive years of Kharif2016 and 2017at Fertilizer Research Farm Uttari Pura, Chandra Shekhar Azad University of Agriculture and Technology, Kanpur (Uttar Pradesh). The field experiment was imposed to evaluate the effect of pesticide and integrated nutrient management systems on the content of major nutrients in the grain of basmati rice PB-1509. The importance of the NPK component is grater because they are found in lower concentrations in most Indian varieties.

Today water discharges from industries are the major causes of water pollution resulting in destabilized ecosystems. Hence, it is necessary to monitor the levels of these pollutants as well as develop technologies for the treatment of waste water. Hence, the present study was attempted to analyse the commonly occurring heavy metals in water and organisms in two stations, Musiri and Mukkombu of the River Cauvery.

The genetics of grain yield and its attributes were studied using diverse cytoplasmic male sterile lines in 144 hybrids developed by crossing six A- and their six B-lines with 12 R-lines of pearl millet in a line x tester mating design. The six A- lines 81A1 and 8A1 (A1 ), Pb 313A (A2 ), Pb 402A (A3 ), 81A4 and 81A5 and their corresponding B- lines represented five different systems of male sterility were very diverse.

A long-term field experiment was carried out in alluvial soil with conservation agriculture practices like Zero tillage (ZT), Permanent bed (PB) and Conventional tillage (CT) to see the impact on Physico-chemical Properties of soil under rice based cropping systems. After completion of 7th cycle of experiment (2018), soil samples were collected from each plot and analysis processes were executed. The results obtained from the study show that the conservation agricultural practices increased the organic carbon 0.47 to 0.71%, cation exchange capacity 9.76 to 13.

In India rice-wheat cropping has been adopted widely which leads to deterioration of soil fertility and decrease in water use efficiency. In addition to these change in climate, vagaries of monsoon also leads to decrease in yields of the crop. Conservation agricultural (CA) based management practices together with nutrient management have demonstrated to produce more with less by these way it also conserve and sustain natural resources. In north eastern India maize crop is grown alternative to rice based cropping system due to variability in climatic condition and degradation of resources.

This study aimed to evaluate the effects of three sodium hypochlorite (NaOCl)-endodontic irrigation procedures used alone or in combinations with two intermediate dressing materials on bond strengths of two adhesive composite systems to coronal dentin. Surfaces were treated with NaOCl or NaOCl–Glyde-File-Prep (H2O2 and EDTA) with or without chlorhexidine (CHX) as a final rinse. Intermediate dressing materials of calcium hydroxide (Ca(OH)2) and sodium perborate (SP) were combined with surface treatments. Surface treatment groups (n = 10/group) included (1) distilled water (control), (2) 5.

We have studied the superconducting transition of the high-Tc Li-doped Bi(Pb)-Sr-Ca-Cu-O superconductors by the DC-resistivity and AC-susceptibility measurements. It was found that Li+ cations are partially substituted for Cu2+ ions. Doping hole by Lithium substitution was supposed to take place in both OP and IP CuO2 planes.
