Air pollution is a consequence of human activities, especially in the period after industrial revolution, which has many (direct and indirect) effects on the human and the environment around him. Among different kinds of pollutions, those related to industries and mines are much more dangerous. Therefore, it is necessary to identify these pollutions and specify them so as to reduce the harmful ...

The wave growth characteristics during the onset of summer monsoon in a swell dominated open ocean at a location off the west coast of India at 14 m water depth are studied. 67% of the measured waves are due to the swells arriving from south and south-west and the balance was due to the seas from south-west to north-west. Wave age of the measured data indicates that the measured waves are young...

The physical development of cities is always faced with natural barriers. The physical development of the city of Zabol, located in the Sistan plain, is threatened specifically with the development of sand dunes. For this reason, the region’s drought conditions were investigated and the standardized precipitation index was calculated. The results showed that with the drying of Hamoon Lake, the ...

The Lut Block (Eastern Iran) extends over 900 km in a north-south direction and is only 200 km wide in an east-west direction. It is confined by the Nayband fault and Shotori Range on the west. The eastern edge is bordered by the Sistan suture zone and Nehbandan Fault. The northern termination of Lut Block is the depression of Kavir-e-Namak and the Great Kavir Fault.

Derelict nets are found in large numbers on parts of Australia’s northern shores and particularly within the Gulf of Carpentaria (Figure 1). The direction of the winds and ocean currents at different times of the year influences where and when these derelict nets wash ashore. On the eastern side of the Gulf (Cape York) the derelict nets arrive with the north-west monsoon winds of the wet season...

Xylem sap flux density (Fd) was measured, on a 43-year-old (mature) and three 4-year-old (young) mango (Mangifera indica L.) trees, using Granier-type probes. The relative influences of environmental variables were examined under well-watered condition. Circumferential variation in Fd was also investigated by placing sensors on the north, south-west and south-east sides of the mature tree. Sap ...
