Similar to random sea waves, forces on the offshore structures due to waves are random. These forces can be mainly divided into two components, namely, inline forces and transverse or lift forces. The random nature of lift forces is more complicated than that of inline forces and both should be combined for design purposes. In the present paper, two different approaches have been used to determ...
Staphylococcus aureus strains producing the bacteriophage-encoded staphylococcal enterotoxin A (SEA) were divided into two groups, high- and low-SEA-producing strains, based on the amount of SEA produced. After growth under favorable conditions in batch cultures, 10 of the 21 strains tested produced more than 1,000 ng/ml SEA, and 9 strains produced less than 10 ng/ml SEA; two enterotoxigenic st...
This research was conducted at the research field of West-Azerbaijan (Saatloo station, 45° 10′ 53˝ E/ 37° 44′ 18˝ N and 1338 m above sea level), located 25 km from Urmia city (Iran) during 2019-2020 cropping seasons, as a factorial layout based on randomized complete block design with three replications. The first factor was irrigation regime at three levels (supplying 100, 75 and 50% of net ir...
The maritime land–sea communication channel experiences multipath shadowing and fading due to ships, onshore offshore structures, reflections from the sea surface. When using low altitude antennas, surface itself can block propagation of radio waves when first Fresnel zone is obstructed. latter occur within a few kilometres transmitter at microwave frequencies. Sea are stronger than ground high...
The subject of information technology and communications in education has, for a while, been discussed and it has been brought up in the special education too, but the main point we are planning to discuss in this article is the optimal application in the classroom and or the management in the application of technology. In practice, helping to expand teachers' skills in information technology ...
