The water distribution in human osteoarthritic articular cartilage has been quantitatively characterized using terahertz time-domain spectroscopy (THz TDS). We measured the refractive index and absorption coefficient of cartilage tissue in the THz frequency range. Based on our measurements, the estimated water content was observed to decrease with increasing depth cartilage tissue, showing good...

background: this study was carried out to determination of heavy metals (cd, cr, cu, fe, pb, ni and zn) concentration in upstream and downstream of the entry of the wastewater (untreated urban, traditional slaughterhouse waste, leachate from solid wastes has accumulated in river and  run off waters flowing across the city ) to the tembi river. methods: samples were collected for 1 year, before ...

objectives: the aim of this study was to assess and compare the water sorption and flexural strength of thermoplastic and conventional acrylic resins. materials and methods: water sorption and flexural strength were compared between a thermoplastic modified polymethyl methacrylate (pmma) denture base resin (group a) and a heat-polymerized pmma acrylic resin (group b) as the control group (n=10)...

to study the effect of nitric oxide on longevity and some qualitative characteristics of cut carnation flowers (dianthus caryophyllus cv. nelson), cut flowers were treated for 48 hours with sodium nitroprusside (snp) as a source of no° donor at four concentrations (0, 20, 50 and 100µm) alone and in combination with other such ethylene inhibitors as thidiazuron and sucrose in a completely random...

The absorption of volatile fatty acids (VFA) and the influence of VFA on the net transport of inorganic electrolytes and water were examined in the temporarily isolated colon of the conscious goat. Perfusion of the colon with a solution similar in content to that normally present in the cecal outflow showed that the net absorption of VFA was more rapid than that of any other ion present in the ...

The Athel tree, Tamarix aphylla (L), can potentially be used as a biomass crop to help manage saline subsurface drainage water in arid land irrigated agriculture. In this study, Athel wood was used to manufacture medium-density particleboard with an aim of developing new applications for the saline wood. The research investigated the effects of different types of adhesives, particle sizes, bark...

The composition and physical properties of aged atmospheric aerosol were characterized at a remote sampling site on the northern coast of Crete, Greece during the Finokalia Aerosol Measurement Experiment in May 2008 (FAME-2008). A reduced Dry-Ambient Aerosol Size Spectrometer (DAASS) was deployed to measure the aerosol water content and volumetric growth factor of fine particulate matter. The p...
