Aim. To develop the content of adhesive composition, being one stages in developing transdermal therapeutic system with anti-inflammatory action. Materials and methods. Using organoleptic research methods, properties affecting process applying to base subsequently quality finished product were studied. Color, consistency homogeneity determined visually, features mass recorded. determine optimal...
• Enhanced bacteria inactivation at low water temperature by UVA- and solar-based AOPs. Mechanism of suggested. Preliminary cost estimation AOPs was performed. Carbon footprint in Spain Finland compared. In this work the effect (6 ± 1 °C 22 °C) on (10 4 –10 6 CFU mL ?1 ; Pseudomonas spp. , Aeromonas spp . Enterobacter spp.) simulated aquaculture streams (SAS) using UVA based advanced oxidation ...
Abstract The aim of the study was to investigate impact three types polysiloxane microspheres on barrier properties, structure and mechanical properties paper. An influence new silicon filler cellulose paper sheet analyzed. Polysiloxane were used as an additive introduced into network cellulosic fibers in order obtain functional following research: M1 hydrophilic average diameter 23.5 µm, M2 hy...
Enantiomers o f N-trifluoroacetyl-amino acid methyl esters in CC14 solution, after addition of the chiral polysiloxane (L)-Chirasil-Val, display a chemical shift nonequivalence AA5 in both 'H NM R and l9F N M R spectroscopy. The effects found for the leucine and valine deriva tives can be correlated with the thermodynamic parameters o f interaction in the undiluted sys tem, as determined by g...
4 Isomeric polycyclic aromatic hydrocarbons (PAH) with two to six rings in coal-derived products and in a carbon black were separated, identified, and quantified by using capillary column gas chromatography and gas chromatography-mass spectrometry. A newly synthesized smectic liquid-crystalline polysiloxane and a conventional polymethylsiloxane were utilized as stationary phases. Many previousl...
In the described technique, a vinyl polysiloxane material is used as a matrix for the indirect fabrication of multiple custom-cast posts and cores. The matrix technique enables the clinician to fabricate multiple posts and cores in a short period of time. The form, harmony, and common axis of preparation for all cores are well controlled before the definitive crown/fixed partial denture restora...
