background: magnetized water has made many improvements in industry, agriculture and medicine. however its utilization in medicine still remains controversial. objective: in this study we aimed to investigate the effects of magnetized water on height of epithelial cells in pre-implantation stage endometrium and fallopian tube and number of corpus lutea in female mice. materials and methods: e...
this work presents a model for calculating the effective thermal conductivity of nanofluids. the proposed model includes the effects of nanoparticles and thermal conductivity base fluid.we will focus on experimental of the volume concentration parameter and temperature on thermal conductivity, nano-fluid combination and multi-walled carbon nanotubes-oxide / copper-paid deionized water. th...
in this study, a new method for joining aluminum tubes in subsurface structures using steel converting and aluminum welding are presented and reviewed. but near the weld area is under high thermal cycle and will cause residual stresses in heat affected zone. therefore for assessment of proposed connection from the perspective of residual stress by using the finite element method welding of tube...
The dimensions of tracheal tubes and connectors in common use were measured together with the resistance to breathing at flow rates occurring in babies breathing quietly. The outside diameters of rubber tubes varied more than those of plastic tubes. The main factors influencing resistance were the internal diameter and a sudden change in diameter or direction of flow. These are of particular im...
