In this study, the purpose was to improve outdoor performance of cement bonded wood composite due their biodegradation and sensitivity moisture especially in warm humid climates. Cement composites were treated with different concentrations (10 %, 25 50 75 % 100 %) water repellent. Water repellent used an organo-silicon based, nano-sized, eco-friendly, water-based agents. Dipping pressure system...

Swelling is commonly observed in austenitic stainless steels irradiated at high doses and temperatures, such as fuel claddings Fast-Breeder Reactors (FBR), a consequence of the formation irradiation-induced nanovoids. Macroscopic embrittlement has been reported above critical swelling level. Several physical explanations have proposed void-related fracture mechanisms phase transformation associ...

A total of 50 pairs of pig eyes was exsmined by meam of ultraPound pachymetry (&h-Pen, Mentor and DGH-Pachette 500, Technomed). The comeal thickness was de&m&d inunediately ai?er em~~leation and after 1) storage in a moist chamber; 2) storage io aqus bide&; 3) Dholoablation with the excimer-laser. l&.&The swelling of different almeas underlied high fluctuations, whereas the differmca between th...

Isolated frog skin epithelia undergo marked, but reversible swelling when the external skin surface is bathed with conventional NaCl Ringer's and the internal surface with KCl Ringer's solutions. In 2 hours, epithelial thickness increased by over twofold. When NaCl Ringer's was replaced on both sides of the skin, volume returned to control levels in less than 1 hour. When sulfate, rather than c...

Weak polyelectrolyte brushes exhibit pH-responsive swelling behaviour, tuneable surface 10 In this paper, we demonstrate the growth of two weak polybase brushes by surface-initiated atom transfer radical polymerisation (SI-ATRP) using electrostatically adsorbed polyelectrolyte macro-initiators. Poly[2-(diethylamino)ethyl methacrylate] (PDEA) and poly[2-(diisopropylamino)ethyl methacrylate] (PDP...

We investigated the swelling behavior and density distributions of polyion segments and multivalent counterions in polyelectrolyte brushes within a primitive model that represents both polyion segments and salt ions as charged spheres and the solvent as a continuous dielectric medium. The numerical performance of a previously proposed nonlocal density functional theory (NLDFT) was tested with M...

turnips with a long history of usage, are helpful in preventing breast and prostate cancer, inflammation and body`s immune system dysfunction. in this study, we investigated the effects of chloroform, ethyl acetate and methanolic extracts of brassica rapa l. on cell-mediated immune response in mice. chloroform, ethyl acetate and methanolic extracts of b. rapa glands were prepared by maceration ...
