Humidity

The genetic breeding can provide a practical method for controlling TLB and significantly alleviate the declining trend in taro production. Early cultural disease management has also been recommended in reducing the inoculums level and relative humidity in the field. More in depth studies are required to understand the pathogenicity and the mating types of different races if any of TLB pathogen. Key words: Phytophthora colocasiae, Symptomatology, epidemiology, mating types, pathogenicity,…

experiment yielded less than 100% triphenylcarbinol was caused by the Grignard reagent reacting with atmospheric water or oxygen instead of reacting with benzophenone due to the highly reactive nature of the Grignard reagent and a constant presence of humidity and moisture inside the laboratory. Although extra precautions were taken to dry to glassware and a CaCl2 drying tube was used, there was an unavoidable exposure of the Grignard reagent to atmospheric oxygen and water due to the operating…

In modern Western society, avoiding contact with the numerous pollutants and substances that can trigger an asthma attack is virtually impossible. In the home, the workplace, even in the air we breathe, we're surrounded by an endless list of potential asthma triggers. A vast range of stimuli can trigger asthma attacks. Chief culprits include dust mites, air conditioning (which cycles offending substances into the air we breathe) and something as simple as cat dander! Individual asthmatics,…

ASTM STANDARDS Short introduction – ASTM standards are consensus standards for systems, services, materials and products. ‘ASTM International’ is one of the largest voluntary standard developing organization in the world. It is a non-profit organization that provides a forum for the development and publication of international voluntary standards. There are approximately 12,575 ASTM standards that operate globally. TESTING ASTM STANDARDS- Scope- There test methods help in the determining of…

Research Question How does the change in hydrochloric acid concentration affect the rate of reaction between sodium thiosulfate (Na2S2O3(aq)) and hydrochloric acid (HCL(aq))? Background to the Research question Collision Theory Back in 1916, scientists William Lewis and Max Trautz proposed the collision theory, which qualitatively explains how chemical reactions take place and why reaction rates change for various reactions. Chemical reactions involve collisions amongst reactant particles or…

The Earth is considered a biosphere because other life that it sustains. However, what characteristics makes a biome and how do those characteristics shape what a biome is? Researcher claim things like climate and landforms make up areas like biomes. Through research and studies, one can accumulate ideas as to how earth’s characteristics make up its biomes. There are many different types of biomes but three are seven main types that can be split up into sub biomes. Two biomes, like the…

pier, all for the modest price of $5. - Low Humidity. Often overlooked by new photographers until encountered, humidity can offer some trepidations. Water vapor on a lens caused by the rapid change in environment affects lens clarity producing undesirable results. Difficult to acclimate, it could potentially remain problematic for several minutes resulting in a possible lost photo opportunity! Again, shooting out of season proved beneficial, low humidity made this issue a moot…

skin and breed in dust found within the home. The conditions within our homes make it an ideal place for them to live and survive. With better insulation methods in modern society, air circulation and ventilation has decreased, thus increasing the humidity of homes. With climate in particular being key to their survival, dust allergies are on the increase.…

Fertilizer was very risky because no fertilizer was proven to work. The humidity was bad enough that trucks overheated after running for 5 minutes. You could hardly walk around the barn without getting dehydrated. The humidity was BAD, Especially in the already humid silo. The unloader motor was a huge subject to the humidity. The motor would only work if he hid it and it was out of the humidity. tim told himself that he wouldn’t Just Farm. He would redesign something to make this…

Grand Canyon - just to name a few - are no more than a half day drive from Goodyear. Also, even though the summer temperatures run about 10 degrees hotter here, than in Florida, the difference in humidity makes it much more bearable. Of course, with the good, always comes some bad. The very low humidity makes for a lot of dust in the air. It seems like I’m always hosing down the house windows, mopping the floor, or getting the car washed. Luckily, many of the car washes out here offer…
