Opis:
This investigation aim to evaluate the effect of heat wave on health of human, so to achieve this 40 blood samples for person exposed to heat wave were drawn most patients were attend to specialists in hospital laboratories (Medical City, Ibn al-Baladi, Sheikh Zayed, Kadhimiya Educational). The patients aged 10–60 years, male (20) and female (20). CBC analyzes was performed. The result of the presents study recorded a highly signifi cant difference in total (mean and percent) as compared with the normal value of the CBC analyze the result for total (mean and percent) for male the factors CRP, ESR, WBC, PCV, PL (15.5, 43, 11.35, 28.5, 215) respectively (100%, 100%, 100%, 100%, 100%) and the result for total (mean and percent) for female the factors CRP, ESR, WBC, PCV, PL (15, 43.5, 11.35, 31, 220.5) respectively (100%, 100%, 100%, 100%, 100%). According to the result we can conclude that there was a highly significant deferent in mean value for patient compared with the normal value which is the mean cause of hard attack which lead to death. The study is the first of its kind in the Department of Atmospheric Sciences in Iraq.

Opis:
The Ti₃AlC₂-, (Ti,Nb)₃AlC₂- and Ti₂AlC-based materials turned out to be more resistant than Crofer JDA steel in oxidizing atmosphere as 1000 h long tests at 600°C have shown. But the amounts of oxygen absorbed by the materials during testing were different. The Ti₂AlC-based material demonstrated the lowest oxygen uptake, (Ti,Nb)₃AlC₂-based absorbed a somewhat higher amount and the highest amount was absorbed by Ti₃AlC₂-based material. Scanning electron microscopy and the Auger study witnessed that amounts of oxygen in the MAX phases before the exposure in air were as well different: the approximate stoichiometries of the matrix phases of materials were Ti_{3.1-3.2}AlC_{2-2.2}, Ti_{1.9-4}Nb_{0.06-0.1}AlC_{1.6-2.2}O_{0.1-1.2} and Ti_{2.3-3.6}AlC_{1-1.9}O_{0.2-0.6}, respectively. The higher amount of oxygen present in the MAX phase structures may be the reason for higher resistance to oxidation during long-term heating in air at elevated temperature. The studied materials demonstrated high stabilities in hydrogen atmosphere as well. The bending strength of the Ti₃AlC₂- and (Ti,Nb)₃AlC₂-based materials after keeping at 600°C in air and hydrogen increased by 10-15%, but the highest absolute value of bending strength before and after being kept in air and hydrogen demonstrated the Ti₂AlC-based material (about 590 MPa).
