The uniaxial compression response of manufactured sand mortars proportioned using different water-cement ratio and sand-cement ratio is examined. Pore structure parameters such as porosity, threshold diameter, mean diameter, and total amounts of macropores, as well as shape and size of micropores are quantified by using mercury intrusion porosimetry (MIP) technique. Test results indicate that s...

abstract population increase, limitation of water resources, and increasing volume of municipal wastewater, has caused the necessity of wastewater reuse. application of wastewater on soils seems to be the most economical method of its disposal and by percolating wastewater through the soil, its chemical quality is improved. for this purpose, a greenhouse experiment was carried out with polyethy...

objective(s): in this study, drug loaded electrospun nanofibrous mats were prepared and drug release and mechanism from prepared nanofibers were investigated.  materials and methods: paclitaxel (ptx) loaded polylactic acid (pla) nanofibers were prepared by electrospinning. the effects of process parameters, such as ptx concentration, tip to collector distance, voltage, temperature and flow rate...

PURPOSE Tumor grading is an important part of breast cancer diagnosis and currently requires biopsy as its standard. Here, the authors investigate quantitative ultrasound parameters in locally advanced breast cancers that can potentially separate tumors from normal breast tissue and differentiate tumor grades. METHODS Ultrasound images and radiofrequency data from 42 locally advanced breast c...

The rehabilitation of sandy desertified land in various dryland ecosystems by different management practices has a great potential to increase aggregate stability and improve soil quality. However, plants in general may have a different ability to sustain soil. The objective was to determine the effects of reclamation practices including Haloxylon ammodendron and Atriplex canescens plantation o...

the aim of this study was to estimate the influence of selected environmental parameters on the fish larval distribution and abundance between october 2012 and september 2013 in the mangrove estuarine area of marudu bay, sabah, malaysia. fish larvae samples were collected monthly using plankton net of 350 mm of mesh size with a mouth opening of 40.5 cm in diameter through 20 min surface tows. f...
