The article discusses the influence of complex additives on strength and resistance cement composites to environmental impacts. One - PFM-NLK (concrete modifier)- a factory fabricated mixture superplasticizer with addition air-retaining water proofing substances. Another one is additive containing superplasticizer, sodium tetraborate boric acid.Common denominator content superplasticizer. It al...

the use of wood preservatives is a suitable method to protect wooden products from termites attack. the effect of a glycol borate wood preservative and termiticide (available commercially as bora-care) alone and in combination with furfural were evaluated against m. diversus silvestri (isoptera: termitidae). the major termite pest in khouzestan province, iran in choice and no-choice tests. it w...

From the chemical bond viewpoint, the second order nonlinear optical (NLO) responses of some typical borate crystals with various crystal structures have been quantitatively studied. The correlations between structural characteristics and second order NLO properties of selected borate crystals are discussed. Calculations show that the isolated BO3 infrastructure is advantageous for borate cryst...

A positive-tone extreme ultraviolet (EUV) photoresist was obtained via the exchange of hydroxide ions tin-oxo-hydroxo cages with tetrakis(pentafluorophenyl)-borate. Thin films were after spin coating on silicon substrates and exposed to line patterns in interference lithography at 92 eV (13.5 nm). For low doses development ethylbenzene positive tone obtained. In contrast, tetrakis(4-methylpheny...

Of 235 strains of coagulase-positive Staphylococcus aureus studied, 221 or 94% were inhibited by 1.5 x 10(-8)m sodium borate, whereas only 6 of 57 (10.5%) coagulase-negative strains were inhibited by the same borate concentration. Four of the six coagulase-negatives were food poisoning strains and one was a hospital pathogen. Borate sensitivity was found to correlate well with lysozyme and alph...

The concentrations of free fucose and other sugars in urine of cancer patients and healthy subjects were analyzed by high-performance liquid chromatography. After the urine samples were dried, we coupled the sugars in the residue with 2-aminopyridine to be detected as fluorescent derivatives. We then analyzed the pyridylamino derivatives of the sugars with an anion-exchange column and borate bu...

More than 40 chromatographic peaks representing carbohydrates have been separated from human urine by a carbohydrate analyzer that makes use of anion-exchange chromatography. Ten of these separated carbohydrates have been identified by gas chromatography of their trimethylsilyl derivatives, which were formed by reaction with N-trimethylsilylimidazole. The borate buffer from the anion-exchange s...

The electrochemiluminescence (ECL) of Ru(bpy)(3)(2+) at bare and single-wall carbon nanotube (SWNT) modified glassy carbon (GC) electrodes has been employed for the determination of melamine for the first time, giving a linear response (R(2) = 0.99682) for melamine concentration from 1.0 × 10(-10) to 1.0 × 10(-5) M at a bare GC electrode in pH 10 borate buffer, and the detection limit is 1.0 × ...

In 1957, protein rich in cysteine able to bind cadmium was isolated from horse kidney and named as metallothionein according to its structural properties. Further, this protein and metallothionein-like proteins have been found in tissues of other animal species, yeasts, fungi and plants. MT is as a potential cancer marker in the focus of interest, and its properties, functions, and behavior und...
