Similar problems have been reported in India, with both mealy bugs [93] [94] and aphids [95] although a survey of small Indian farms between 2002 and 2008 concluded Bt cotton adoption has led to higher yields and lower pesticide use, decreasing over time.
Bt cotton was created through the addition of genes encoding toxin crystals in the Cry group of endotoxin. [1] When insects attack and eat the cotton plant the Cry toxins or crystal protein are dissolved due to the high pH level of the insect's stomach.
Electron micrograph of Bluetongue virus, scale bar = 50 nm. Bluetongue (BT) disease is a noncontagious, arthropod-borne viral disease affecting ruminants, [1] primarily sheep and other domestic or wild ruminants, including cattle, yaks, [2] goats, buffalo, deer, dromedaries, and antelope. [3]
Chronic solvent-induced encephalopathy (CSE) is a condition induced by long-term exposure to organic solvents, often—but not always—in the workplace, that lead to a wide variety of persisting sensorimotor polyneuropathies and neurobehavioral deficits even after solvent exposure has been removed.
Melioidosis is an infectious disease caused by a gram-negative bacterium called Burkholderia pseudomallei. [1] Most people exposed to B. pseudomallei experience no symptoms; however, those who do experience symptoms have signs and symptoms that range from mild, such as fever and skin changes, to severe with pneumonia, abscesses, and septic shock that could cause death.

While the Boudouard reaction is used deliberately in some processes, it is undesired in others. In the gas cooled, graphite moderated British nuclear reactors (Magnox and AGR) reaction between the CO 2 coolant and the graphite moderator had to be avoided or at least kept to a minimum. As the equilibrium of the reaction shifts in favor of carbon ...
GFAA spectrometry instruments have the following basic features: 1. a source of light (lamp) that emits resonance line radiation; 2. an atomization chamber (graphite tube) in which the sample is vaporized; 3. a monochromator for selecting only one of the characteristic wavelengths (visible or ultraviolet) of the element of interest; 4. a detector, generally a photomultiplier tube (light ...
