Wood is a sustainable renewable material that widely used in the building sector. Due to recent trends green initiatives European and other countries, wood waste becoming more popular for sound absorption insulation because of its renewability. Recycled granulated charcoal an effective acoustic treatment. In this study, we investigated coefficients raw species: birch (Betula pendula), pine (Pin...

Cross-laminated timber (CLT) elements in structures may be exposed to high perpendicular-to-grain compressive stresses, which often require reinforcement improve the inherently low strength and stiffness of perpendicular-to-grain. This experimental study evaluates behaviour CLT when reinforced by hardwood dowels. Groups 3 5-ply specimens with dimensions 400 mm × mm, without dowel reinforcement,...

A simple and rapid column-switching ion chromatography with non-suppressed conductivity detection method was developed for simultaneous determination of L-carnitine, choline and mineral ions (free sodium, potassium, magnesium and calcium ions) in milk and powdered infant formula samples. On-line sample clean-up was achieved on the pretreatment column Dionex IonPac NG1 (50 mm 4 mm, i.d.), with p...

In this study, gold nanoparticles (AuNPs) were synthesized following a bioreductive route using extract of Eriobotrya Japonica leaf. For the synthesis nanoparticles, firstly, leaves collected from Eastern Black Sea region (Akçaabat-TRABZON) in Turkey and dried. Secondly, 20 g dried sample was shaken 400 mL distilled water for 180 min. extracted laboratoary microwave device at 4 minutes, 600 W l...

Combined QM/MM calculations of an activesite of Cytochrome P450cam have been performed, before and after a binding process of Cytochrome P450cam to Putidaredoxin. The calculations have been carried out for two coordination spheres of the heme active-site of Cytochrome P450cam, namely a 5-coordinated, and a 6coordinated system of this protein having a water molecule as a 6th ligand. An experimen...

A printed circuit heat exchanger (PCHE) is an efficient and compact that can work under high temperature pressure. For Z-shaped channel PCHEs, the corner structure could enhance transfer at expense of increasing flow resistance. In order to optimize structural design control pressure loss caused by corner, a three-dimensional numerical simulation using ICEM Fluent conducted study characteristic...

Ferrofluid instabilities in DC magnetic fields for an Isopar-M based ferrofluid with saturation magnetization of about 400 Gauss. a) 1200 Gauss 5 mm diameter magnet behind small ferrofluid droplet surrounded by propanol to prevent ferrofluid wetting of 1 mm gap glass plates; Peak pattern with magnetic field perpendicular to ferrofluid layer. The peaks initiate in a hexagonal array when the magn...
