The aims of this study were to examine, in a prospective, controlled way, the effect of the sperm deposition site in the oocyte and the mode of oolemma breakage in intracytoplasmic sperm injection (ICSI) on fertilization and embryo development rates. In the first trial (100 cycles in total), the spermatozoa were deposited further from the meiotic spindle(More)
The determination of strontium in human blood samples by ICP-AES is described. For the analysis no chemical separations were required after microwave destruction. A mean value of 11.4 +/- 0.83 micrograms/l is found for normal whole blood. The limit of detection of the method is 0.3 microgram/l. As a possible application the enhancement of the strontium(More)
Elemental emissions during firing in a shooting range were measured for different types of ammunition. When using Hirtenberger bullets, lead, barium, antimony and to a lesser extent copper and arsenic were the primary metal pollutants. Stationary sampling at three locations in the range did not reveal large concentration gradients. Large concentration(More)
A specific heat exchanger has been developed to transfer heat from flue gas to the working fluid (hot air) of the Ericsson engine of a solid biomass-fuelled micro combined heat and power (CHP). In this paper, the theoretical and experimental energetic analyses of this heat exchanger are compared. The experimental performances are described considering(More)
