plant cover is one of the most important factors affecting infiltration rate of water into the soil and decreasing runoff. distribution of plants in arid and semi-arid areas is almost patchy and form different patterns. one of the fascinating patterns is ring-shaped growth pattern. ring patterns of varying size are formed by clonally reproducing grasses, sedges and even shrubs growing in resour...

BACKGROUND Coronary microembolization (CME) has been frequently seen in acute coronary syndromes and percutaneous coronary intervention. Small animal models are required for further studies of CME related to severe prognosis. This study aimed to explore a new mouse model of CME. METHODS The mouse model of CME was established by injecting polystyrene microspheres into the left ventricular cham...

A process is described which involves infiltration of aluminum nitrate into partially sintered (porous) zircon bodies. Infiltration kinetics were studied using infiltration curves with two distinct regions. The final infiltrated samples were sintered at 1600 °C for 2 h and yielded specimens containing the tetragonal zirconia.The experimental results show that in spite of the similar porosity of...

In this research, infiltration behavior of W-Ag composite compacts with Nickel and Cobalt as additives has been investigated. Nickel and Cobalt were added to Tungsten powder by two distinct methods: mixing elementally and reduction of salt solution. The coated Tungsten powders were compacted under controlled pressures to make porous skeleton with 32-37 vol. % porosity. Infiltration process was ...

introduction: many patients suffer from mild, moderate or severe pain during or after root canal therapy. theoretically, post-operative pain control can be achieved by using long-acting local anesthetics. the aim of this study was to evaluate the efficacy of a long acting anesthesia, bupivacaine, on preventing post-operative pain associated with endodontic treatment, and to compare it with lido...

background: neutrophil infiltration plays an important role in inflammatory reactions following spinal cord injury (sci) and these cells cause substantial secondary tissue damage. the purpose of this study was to determine the effect of oleuropein (oe) on myeloperoxidase (mpo) activity as an index of neutrophil infiltration. methods: rats were randomly divided into four groups of 7 rats each as...

Aeolian sandy soil in mining areas exhibits intense evaporation and poor water retention capacity. This study was designed to find a suitable biochar application method improve infiltration minimize for aeolian sand soil. Using the indoor column method, we studied effects of three patterns (A (0–20 cm mixed sample mixed-based soil), B (0–10 10–20 C soil)), four amounts (0% (control, CK), 1%, 2%...
