Inorganic compound

During the first phase called carbon fixation, carbon dioxide (Co2) is fixed from an inorganic molecule to an organic molecule (3-PGA) by the enzyme called RuBisCo. The second phase called reduction, is where ATP and NADH help reduce 3-PGA into G3P and ATP and NADPH are then converted to ADP and NADP+. In the final phase called regeneration…

NATURAL LONGEVITY OF TREE SEEDS. The period for which seed can remain viable without germinating is greatly affected by its quality at the time of collection, its treatment between collection and storage and the conditions in which it is stored. According to Harrington (1972) one of the two main factors influencing seed longevity is seed moisture content. Seeds are hygroscopic and their moisture contents come into equilibrium with those of the atmosphere. Nevertheless, seed longevity varies…

Abstract In this paper CuO-NH-NH2 nanoparticle was synthesized and used to remove anionic dyes from single and binary systems. The scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), Energy-dispersive X-ray spectroscopy (EDAX) and X-ray diffraction (XRD) were used to characterize the nanoparticle. Direct Red 80 (DR80) and Direct Green 6 (DG6) were used as anionic dyes. The effect of adsorbent dosage, dye concentration and pH on dye removal was evaluated. Kinetic…

order to create a “superbug.” With the new mutated “superbug” they hope to improve an organism that will be able to withstand high amounts of radiation and be able to convert radioactive material located at nuclear waste sites into less harmful compounds. (DeWeerdt, 2001). D. radiodurans has been called “the world’s toughest bacterium” and there has not been much opposition to that…

air quality. Although Air quality is only effected when many areas are on burnt on the same day which could lead to effecting humans health since more then 90 percent of the particles emissions from control burning constrains hundreds of chemical compounds, a few that are known to be toxic. It is proven that repeated exposure to smoke concentration can contribute to respiratory problems and cancer. But, the risk has been estimated to be less than one in a million. Prescribed Fire. 2015. Fire…

Chapter one 1.0 Introduction 1.1 Background information and rationale Maize (Zea Mays L.) is one the most important cereal crop in sub-Saharan Africa and Zimbabwe. According to FAO statistics the total amount of maize produced worldwide is estimated at 785 million tons and United States of America is the largest producer and contributing 42%, Africa produces 6.5% with Nigeria being the largest African producer with nearly 8 million tons, followed by South Africa. Based on area and production,…

Water is what keeps our world spinning, from plants and animals, to organisms and human beings. It wasn't until this semester, that I received a deeper appreciation of this liquid that we sometimes take for granted. Being around water since birth is what inspired my topic, “Water and Religion.” I was baptized as a baby, and now in my twenties I am wondering why water played such a crucial role. I will dive back in time to see where earths water came from, who were the first to use it, who…

Thermal energy strorage Thermal Energy Storage is the temporary storage of high or low temperature energy for later use, bridging the gap between requirement and energy use. The storage cycle might be daily, weekly or seasonal depending on the system design requirements, and whilst the output will always be thermal, the input may be thermal or electrical. Principle 1) Sensible Heat Storage Heating a liquid or solid, without changing the phase: This method is called sensible heat storage.…

Benedictine University Professor, David Milen, Ph.D.,MPH, MS, BA, AAS Chemical contamination refers to the presence of unwanted substances that make the food, air, or water unfit to use. There are two forms of chemical contaminants organic and inorganic. We have chemical contaminant in the substance that we are using every day. There is property or characteristic for some contaminants which is volatile, this lead to having like these contaminates in our environment. Examples of these…
