Fertilizer efficiency directly affects the production of continuous cropping greenhouse cucumber. So analyzing the fertilizer efficiency is of great significance in providing decision-making support for fertilization of greenhouse cucumber. By establishing the DEA models of continuous cropping greenhouse cucumber and taking existing data samples as study objects, the problems of fertilizer effi...

Birth of babies through in vitro fertilization procedures has Tenewed interest by clinicians as well as laymen in the phenomenon of fertilizatien. In most medical text books, fertilization is treated very lightly giving students the impressien that fertilization is a simple mechanical penetration of a spermatozoon into an egg. This is far frorn the truth. Fertilization comprises ・a series of co...

Chitosan coated iron nanoparticles were synthesized by co-precipitation method and also Nanoparticles evaluate the effect of surface coating on stability toxicity nanoparticles. FTIR amino groups acted as a capping site for Iron stabilization. Invitro cytotoxicity is dependent dose-based their reduction was observed in SKMEL cancer cells administered with different concentration samples. I50 va...

The purpose of this study was to examine: 1) whether caffeine in the fertilization medium under mineral oil is essential for bovine in vitro fertilization by fully capacitated spermatozoa, 2) the minimum concentration of caffeine that shows an adverse effect on the motility of preincubated spermatozoa. Cumulus-oocyte complexes with heterogeneous-appearing ooplasm were matured in in vitro cultur...

In vitro fertilization (IVF) is a process by which an egg is fertilised by sperm outside the body: in vitro . The process involves monitoring and stimulating a woman's ovulatory process, removing an ovum or ova (egg or eggs) from the woman's ovaries and letting sperm fertilise them in a liquid in a laboratory. The fertilised egg (zygote) is cultured for 2–6 days in a growth medium and is then i...
