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:
With high-grade apatite resources exhausted and economic development, enhancing the apatite quality from calcium gangue such as dolomite has a great significance for production. However, it is difficult to separate apatite from dolomite effectively due to the similar surface properties. In this study, the N-carboxybutyl chitosan ($CBC$) was tested as a potential selective depressant to separate apatite from dolomite in the sodium oleate ($NaOL$). Flotation results of single mineral and artificially mixed mineral confirmed the selective depression effect of CBC. The depression mechanism of $CBC$ was investigated using wettability analysis, Fourier Transform Infrared ($FTIR$), and X-ray Photoelectron Spectroscopy ($XPS$) analyses. The results indicated that the $CBC$ adsorption quantity and intensity on the dolomite surface more than that on the apatite surface, which was due to $CBC$ absorbed on apatite surface by hydrogen bonding, while absorbed on dolomite surface mainly through chemical chelating between $Ca$ on the mineral surface and -COO- on the depressant. These adsorption differences led to the flotation separation of the two minerals.
