zaki’s reef is located in the gulf of suez, a narrow portion of the red sea, with exceptionally dry and hot climate and lacks almost all scientific data. this research intends to describe the area’s unique climatology, which may reveal correlations between the reef’s existence at high latitude and extreme climate conditions. air temperature at zaki’s reef fluctuated between 0.3 and 58.6oc with ...

Introduction Thousands of chemical substances, including toxic, persistent, bioaccumulative substances (TPBS), are produced and used world-wide annually 1 . These volatile and semivolatile TPBS may be transported by air both in gaseous phase and adsorbed to atmospheric particles 2 prior to deposition in soil and water. Due to the grasshopper effect, TPBS released may evaporate in warmer climate...

OVERVIEW Global climate change is expected to have broad health impacts. If current warming trends continue, heat waves, floods, and droughts and their attendant physical effects are likely to become more frequent and severe. Warmer air temperatures can influence the concentration of regional air pollutants and aeroallergens. Less direct health impacts may result from the disruption of ecosyste...

In this study, it was aimed to investigate the porosity / compactness of the knitted structures made from cotton and modal yarns and to evaluate the air permeability property for sportswear. In the experimental section, cotton and modal yarns spun in different counts ( Ne 30, Ne 40 ) with the same twist coefficient of αe = 3.53 and 3.3 respectively were knitted as single jersey fabrics in the s...

Natural unforced variability in global mean surface air temperature (GMST) can mask or exaggerate human-caused global warming, and thus a complete understanding of this variability is highly desirable. Significant progress has been made in elucidating the magnitude and physical origins of present-day unforced GMST variability, but it has remained unclear how such variability may change as the c...

Heat stress occurs when the body cannot release heat and cool itself. When the air temperature is as warm as or warmer than a person's skin, blood brought to the skin's surface cannot efficiently release heat. Working hard in high heat impedes the body's ability to cool itself because the muscles need extra blood, thus decreasing the amount of blood available to circulate to the skin and intern...
