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...
Background and purpose: Phenol whose carcinogenic property has been evidenced is one the organic compounds found in industrial wastewater. Therefore, this effluent must be treated before it is discharged to the environment. The aim of this study was to investigate whether dried azolla can absorb phenol from aqueous solution. Materials and methods: First, the collected azolla was washed by dis...
The objective of this study was to evaluate bacterial prevalence in 31 root canals of human deciduous teeth with necrotic pulp and periapical lesions using bacterial culture. After crown access, the material was collected using absorbent paper points for microbiological evaluation and determination of colony forming units (CFU). Anaerobic microorganisms were found in 96.7% of the samples, black...
