The binding sites of the oestrogen receptors alpha and beta have a structural requirement for ligands with two oxygen atoms (one of which is phenolic) spaced 11-12 A apart. They are open to many non-steroidal compounds, such as those from plants and the chemical industry. The importance of this interaction is the subject of current food safety research. This article examines the methods of asse...

Rotating biological contactors (RBCs) constitute a very unique and superior alternative for biodegradable matter and nitrogen removal on account of their feasibility, simplicity of design and operation, low land area requirement, low energy consumption, low operating and maintenance cost and treatment efficiency. The present review of RBCs focus on parameters that affect performance like rotati...

12 13 SUMMARY 14 Weibel and Taylor " s theory of symmorphosis predicts that the structural components of the 15 respiratory system are quantitatively adjusted to satisfy, but not exceed, an animal " s maximum 16 requirement for oxygen. We test this in the respiratory system of the adult migratory locust Locusta 17 migratoria by comparing the aerobic capacity of hopping and flight muscle with th...

OBJECTIVES To determine if chronic oxygen dependency (discharge home on supplemental oxygen) in children with bronchopulmonary dysplasia (BPD; defined as requirement for supplemental O2 at 36 weeks postmenstrual age) predicts neurodevelopmental disability rates and growth outcomes at 36 months corrected age (CA). STUDY DESIGN Longitudinal cohort study. SETTING Southern Alberta regional cent...

Adaptation to oxygen deficiency is essential for virulence and persistence of Brucella inside the host. The flexibility of this bacterium with respect to oxygen depletion is remarkable, since Brucella suis can use an oxygen-dependent transcriptional regulator of the FnrN family, two high-oxygen-affinity terminal oxidases, and a complete denitrification pathway to resist various conditions of ox...

Oxygen homeostasis reflects the constant body requirement to generate energy. Hypoxia (0.1-1% O2), physioxia or physoxia (∼1-13%), and normoxia (∼20%) are terms used to define oxygen concentration in the cellular environment. A decrease in oxygen (hypoxia) or excess oxygen (hyperoxia) could be deleterious for cellular adaptation and survival. Hypoxia can occur under both physiological (e.g., ex...

In normal sintering of iron ore, there is a wide difference in temperature the sinter bed between top and bottom; i.e. flame front gradually increases towards bottom because lower part gets longer time for drying preheating by exit gas. Therefore, may have insufficient fusion excessively fused. Thus, quality become inhomogeneous coke breeze requirement becomes higher than actual thermal require...

The requirement for the detection of oxygen in industrial safety applications has historically been met by electrochemical technologies based on the consumption of metal anodes. Products using this approach have been technically and commercially successful for more than three decades. However, a combination of new requirements is driving the development of alternative approaches offering fresh ...
