concentration was the most important variable for the 2,4-D degradation, whereas for diuron, ametryne and the considered mixture was the initial pH. The degradations of the pesticides mixture were favored at an initial pH of 7 and 0.6 g/l of TiO2 concentration.

The World Health Organization has set an acceptable formaldehyde concentration in air of normal indoor conditions of 80 parts per billion (p.p.b.) (100 µg/ml) , which results in a daily total exposure equivalent to > 2000 puffs. For other aldehydes, the safety …

Rootstocks with Vitis berlandieri genetic backgrounds contained lower levels of petiole K at bloom, but these differences were not apparent at veraison and harvest. It is possible that water deprivation because of drip-irrigation or deficit-irrigation practices contributed to this result, as it has not been consistently observed in previous ...

We report the first in situ detection of boron on Mars. ... However, the different possible mechanisms of initial boron concentration from lake waters have important consequences for fluid pH and the resultant borate mineralogy, since possible borate mineral precipitates are dependent on fluid temperature, pH, ...

The creatinine concentration should be 20–400 mg/dL. However, some drug testing laboratories consider a creatinine concentration of 15 mg/dL as the lower end cutoff. One common adulterant, sodium chloride, always produces a specific gravity greater than 1.035 if added at a concentration necessary to produce a false-negative result.

Other names: free thyroxine, free T4, total T4 concentration, thyroxine screen, free T4 concentration. What is it used for? A T4 test is used to evaluate thyroid function and diagnose thyroid disease. Why do I need a thyroxine test? Thyroid disease is much more common in women and most often occurs under the age of 40. It also tend to run in ...

where K is the consistency index (Pa sn), A is the pre- exponential factor (Pa s n ), Ea is the activation energy of flow (kJ mol 1 ), R is the universal gas constant

The K i value was obtained from a corresponding secondary replot of 1/V against inhibitor concentration (Fig. 7D). This secondary replot has an intercept of – K i on the axis of inhibitor concentration.

Chinese star anise ( Illicium verum Hook f.) is a well-known spice used in many cultures. Many populations use it as a treatment for infant colic. Japanese star anise ( Illicium anisatum L), however, has been documented to have both neurologic and gastrointestinal toxicities. Recently, concern has been raised regarding the adulteration of Chinese star anise with Japanese star anise.

The physiologic approach has long been used in assessing acid-base status. This approach considers acids as hydrogen ion donors and bases as hydrogen ion acceptors and the acid-base status of the organism as reflecting the interaction of net hydrogen ion balance with body buffers.

A laboratory treatment model shows that the sequentially alternating use of two antibiotics can be optimized to outperform combination treatments at the equivalent dose.

N-firm concentration ratio is a common measure of market structure and shows the combined market share of the N largest firms in the market. For example, the 5-firm concentration ratio in the UK pesticide industry is 0.75, which indicates that the combined market share of the five largest pesticide sellers in the UK is about 75%.
