Abstract This study aimed to investigate the effect of different activations on properties bio-based activated carbons (BACs) for water treatment. BACs were produced via pyrolysis by carbonization stage and followed four activation procedures. Chemical included introduction metal oxides or alkali structure sawdust-derived BACs, resulting in iron-activated carbon (BAC-Fe), copper-activated (BAC-...

the contamination of water by toxic heavy metals is a world-wide environmental problem. discharges containing cadmium, in particular, are strictly controlled due to the highly toxic nature of this element and its tendency to accumulate in the tissues of living organisms. low concentration (below 5 mg`/l) of cadmium is difficult to treat economically using chemical precipitation methodologies. i...

A dual-flow continuous culture system was used to evaluate the effects of laidlomycin propionate and bacitracin zinc on fermentation, nutrient digestibility, microbial efficiency. Factors were (LP; 2 mg/L volume) (BAC; 1.4 mg/L), treatments as follows: (1) no BAC or LP (CON), (2) without (LP), (3) (BAC), (4) (LP/BAC). fifth treatment supplemented with monensin sodium (MON; 6 mg/L) act a positiv...

Background: The importance of viral protein-2 (VP2) of canine parvovirus (CPV) in binding to human cancer cells, production of veterinary vaccines and diagnostic kits has motivated several researches on producing this protein.Objectives: Our purpose was to construct recombinant bacmid shuttle vectors expressing VP2 of CPV using Bac-to-Bac baculoviral expr...

Biological activated carbon (BAC) filtration is an effective technology for the removal of natural organic matter. However, one potential drawback BAC, especially old that effluents can contain soluble microbial products released from biofilm, which are recognized as more toxic nitrogenous DBPs (N-DBPs) precursors. So far, limited studies reported risk DBP formation potentials (FPs) increase ca...

PURPOSE To evaluate acute corneal epithelial toxicity induced by benzalkonium chloride (BAC) homologs with different alkyl chain lengths using an in vivo electrophysiological method. METHODS BAC homologs with C12, C14, and C16 alkyl chain lengths were used at concentrations of 0.0025%, 0.005%, and 0.01%, respectively. Cytotoxicity of BAC homologs on the normal rabbit corneal epithelial cells ...

Genome sequencing projects are either based on whole genome shotgun (WGS) or on a BAC-by-BAC strategy. Although WGS is in most cases the preferred choice, sometimes the BAC-by-BAC approach may be better because it requires a much simpler assembly process. Furthermore, when the study is limited to specific regions of the genome, the WGS would require an unjustified effort, making the BAC-by-BAC ...

This letter studies the application of backscatter communications (BackCom) assisted non-orthogonal multiple access (BAC-NOMA) to envisioned sixth-generation (6G) ultra-massive machine type (umMTC). In particular, proposed BAC-NOMA transmission scheme can realize simultaneous energy and spectrum cooperation between uplink downlink users, which is important support massive connectivity stringent...

Bacterial artificial chromosome (BAC) clones are effective mapping and sequencing reagents. The 1.1-Mb a/d T-cell receptor locus of humans was mapped and partially sequenced with BAC clones. Seventeen BAC clones covered the 1.1-Mb a/d locus, with the exception of one small gap that was expected from the coverage that a 3.7-fold BAC library is likely to provide. The end sequences of the BAC inse...
