the aim of this study was to examine whether the secreted fluid from the uterus influences the survival and fertilization capacity of fowl sperm in the hen oviduct. hens with either regular uterine fluid secretion or irregular uterine fluid secretion were artificially inseminated through the transfer of sperm into the uterus. twenty-four hours after  artificial insemination, 3 hens with regular...

The most common clinical problem associated with the surgery is long-term aseptic loosening of the implant. The limited durability of the artificial joint, and the difficulty of revision surgery, have limited the potential applications of this treatment, particularly in younger and ...

Needlestick injury including hollow-bore or solid needle • Mucous membrane exposure to potentially infectious body fluid • eg. blood splash to eye • Non-occupational setting • Percutaneous exposure to potentially infectious body fluid • eg. needle-sharing • Mucous membrane exposure to potentially infectiou...

When the natural energy of an oil field is not enough to fluid lift, we need a secondary recovery procedure on the well (normally, this is called artificial lift) [I]. For this case, we can use different techniques such as artificial lift by gas (ALG) [I ] . The idea of the ALG is to inject gas, and in this way to lighten the fluid. The design of this system must be made very carefully. One of ...
