Plant samples of Cardamine hupingshanesis (Brassicaceae), Ligulariafischeri (Ledeb.) turcz (Steraceae) and their underlying top sediments were collected from selenium (Se) mine drainage areas in Enshi, China. Concentrations of total Se were measured using Hydride Generation-Atomic Fluorescence Spectrometry (HG-AFS) and Se speciation were determined using liquid chromatography/UV irradiation-hyd...

We propose a dynamic accumulator scheme from bilinear pairings, whose security is based on the Strong Diffie-Hellman assumption. We show applications of this accumulator in constructing an identitybased (ID-based) ring signature scheme with constant-size signatures and its interactive counterpart, and providing membership revocation to group signature, traceable signature and identity escrow sc...

The current study was conducted to test the efficiency of vegetative part (plant leaves) plant species shrubs and trees involved in forming semi-artificial vegetation city Baghdad, Karkh, uptake accumulating lead element that pollutes air atmosphere. Five sampling sites were selected: Al-Kadhimiyah, Al-Mansour, Al-Ma'aml (Al-Salam district), Al-Adl, Al-Ameriya district intersections (Al-Seklat)...

The issues of using renewable energy sources and, in particular, solar for autonomous power supply to residential buildings and cottages central Russia were considered. Recommendations on assessment reliability supply, selection accumulator batteries capacity, their service life, operation peculiarities are presented. possibility inertial dynamic accumulators accumulate the obtained electricity...

Characteristics of accumulation and tolerance of cadmium (Cd) in green manure crops were investigated to identify Cd-accumulating crops and to clarify the mechanisms involved in Cd accumulation and tolerance. Seedlings of eight crop species were treated with Cd (1 mg l(-1) or 5 mg l(-1)) in the growing medium for 4 d. Cd concentration in leaves of Avena strigosa Schreb. cv. New-oat, Crotalaria ...

In this paper, we present a recent algorithm given by Ogita, Rump and Oishi [39] for accurately computing the sum of n floating point numbers. They also give a computational error bound for the computed result. We apply this algorithm in computing determinant and more particularly in computing robust geometric predicates used in computational geometry. We improve existing results that use eithe...

The quest for eco-friendly electrolytes lead-acid accumulators has necessitated this research. Raw Akamu wastewater (rAWW), a biowaste effluent, was assessed its viability as substitute electrolyte accumulators. Five hundred grams of dent Zea mays L. (yellow maize) weighed the preparation raw using traditional methods. (rAWW) got in process tested pH, microbial and chemical contents. Results in...

Abstract Antimicrobials, heavy metals, and biocides are ubiquitous contaminants frequently detected in water bodies across the globe. These chemicals known as drivers of antimicrobial resistance (AMR), these can select for resistance. Tools processes, therefore, needed to remove from environment tackle environmental component AMR. Aquatic phytoremediation is a nature-inspired green solution env...
