one fundamental strategy for increasing efficiency of plans which aim to develop natural resources is decreasing water loss and using this restricted water optimally. in arid and semi-arid regions such as a large part of iran, increasing period of irrigation which results in decreasing the irrigation costs, without causing water stress to planted sapling is a vital task. in this research we exa...

WITHERS, PHILIP C. Measurement of Vo,, &02, and evaporative water loss with a flow-through mask. J. Appl. Physiol.: Respirat. Environ. Exercise Physiol. 42(l): 120-123, 1977. Equations for the calculation of vo2, vcoZ, and evaporative water loss were derived for use of a paramagnetic gas analyzer with a flow-through respirometry system and an open or closed mask. The magnitude of errors involve...

Let D be a digraph with the vertex set V (D) and the arc set A(D). A subset N of V (D) is k-independent if for every pair of vertices u, v ∈ N , we have d(u, v), d(v, u) ≥ k; it is l-absorbent if for every u ∈ V (D) − N there exists v ∈ N such that d(u, v) ≤ l. A k-kernel of D is a k-independent and (k − 1)-absorbent subset of V (D). A 2-kernel is called a kernel. It is known that the problem o...

In the present study, we tried to reduce the non-specific reactions for measuring anti-Chlamydia pneumoniae IgM antibodies by the ELISA kit of HITAZYME C. pneumoniae Ab-IgM (HITAZYME IgM) by using a new absorbent. We also tried to reset the IgM cut-off index (ID) of HITAZYME IgM by testing serum samples from healthy children and healthy adults with no respiratory symptoms. The results suggest t...

Toxic shock syndrome (TSS) is a rare, life-threatening, acute multisystem illness usually characterized by sudden onset of high fever, diffuse sunburn-like erythroderma and a variety of other signs and symptoms. It may progress rapidly to hypotension and shock with multiple organ failure. Its exact cause is unknown, but in almost all cases there has been an infection with exotoxin-producing str...
