according to the drought as the most important environmental factor that limiting agricultural products and using nitrogen as the most consumed nutrition element in farming system, in this study investigates examined the effect of nitrogen on drought tolerance characteristics, including changes in total chlorophyll content, total protein content, leaf area, phosphorus and peroxidase enzyme acti...

C and delay are two major parameters for evaluating intersection operations. While models and procedures are available to estimate these parameters given some other easily obtainable traffic flow parameters, traffic engineers often have to conduct field measurements to verify the results given by available models and procedures. Capacity and delay models are provided by the 1994 update of the H...

We study the problem of multicasting over a network of multiple-access channels (MACs). The separation-based solution to this problem is to reduce each MAC to a set of noiseless bit pipes via a channel code and then employ network coding. Sometimes, however, the physical-layer structure of the MAC can be exploited more advantageously. In many cases of interest, the MAC output is a (deterministi...

Using an asymptotic solution of the M -impurity thermodynamics of a dilute s-d system, the impurity energy and impurity heat capacity ∆C(T ) are derived for dilute magnetic alloys with spin 1/2 and spin 3/2 impurities. The parameters which enter ∆C are adjusted to fit experimental data on impurity heat capacity of CuCr and (La1−xCex) Al2. Agreement is satisfactory for CuCr, at temperatures belo...

Forty two male brick-field workers of two age groups, viz. 20-29 and 30-39 yrs were studied with a view to determine their aerobic capacity (VO2 max). The average values of VO2 max in l.min-1 showed only small change between the young and the aged groups, but the values of the VO2 max in ml.kg.-1min-1 showed significant difference between the groups due to body weight increase in the aged group...

Muscle strength is important for firefighters work capacity. Laboratory tests used for measurements of muscle strength, however, are complicated, expensive and time consuming. The aims of the present study were to investigate correlations between physical capacity within commonly occurring and physically demanding firefighting work tasks and both laboratory and field tests in full time (N = 8) ...

Porous surfaces have been used all over the world in source control techniques to minimize flooding problems in car parks. Several studies highlighted the reduction in the infiltration capacity of porous mixture surfaces after several years of use. Therefore, it is necessary to design and develop a new methodology to quantify this reduction and to identify the hypothetical differences in permea...

We establish the capacity region of the two-user Finite-Field Fading X-Channel with delayed channel state information at the transmitters. We consider the most general case in which each transmitter has a common message for both receivers and a private message for each one of them. We derive a new set of outer-bounds for this problem that rely on an extremal entropy inequality. This inequality ...

Working as a firefighter is physically strenuous, and a high level of physical fitness increases a firefighter's ability to cope with the physical stress of their profession. Direct measurements of aerobic capacity, however, are often complicated, time consuming, and expensive. The first aim of the present study was to evaluate the correlations between direct (laboratory) and indirect (field) a...
