Salts and molecules have similar characteristics, and many differences whether we can tell by first looks or not. Testing these two only supports the differences, and many structural functions cause these differences. Since salts are ionically bonded, they have different properties and functions compared to the covalent bonded molecules. Salts have a ionic bond, and we can confirm due to their electronegativity. As you move from left to right on the periodic table you would notice that…

3. Results Considering the morphological characteristics of the ecotypes, the cladode shape was elliptic or ovate, the number of spines varied among three classes (many, intermediate or few), the flowers had two types of petal color (scarlet or yellow), the fruit was elliptic or ovoid and the pulp color was white, pale yellow or orange (Table 2). The OFI populations studied showed statistically significant differences for DM of the fruits, F (17, 34.24) = 31.61, p < 0.05, which varied…

Arsenic trioxide was the dust outcome of gold extractions which happened during time period of 1948 to 2004 at the mine. According to the report 2010 it was mentioned that dust was captured as arsenic-rich gas and stored in underground Chambers. 2. How is the Giant Mine Remediation Project using technology to solve the arsenic trioxide…

enter the house and allow the stale air to exit. The effects of VOCs can also be lowered by minimalizing exposure to these compounds. An example of a VOC is methanol, a substance which is toxic if ingested because it metabolises to form Formaldehyde (CH_2 O). Methanol (CH_3 OH) is most commonly found in products such as cigarettes as well as in foods or drinks containing aspartame, an artificial sweetener. Formaldehyde is another toxic VOC which can cause the development of cancer. Formaldehyde…

moiety was also protected as its O-Boc enol carbonate (Figure X.X.X). Transient in situ O-silylation facilitated the preparation of bis-N-Boc nucleosides from unprotected sugars. This strategy allows the protection of nucleosides with a base-stable and acid-labile group suitable for the preparation of base-sensitive oligonucleotides as well as for further manipulation. However, the utility of this diBoc carbamate protection is yet to be explored in oligonucleotide…

Fig 4.12 shows the comparison of product density of hydrotreated GO obtained using CAT-E and CAT-C. The density of hydrotreated GO from CAT-C at 370◦C was 0.8148g/ml whereas at the same temperature the density of hydrotreated GO obtained from CAT-E was 0.8302 g/ml despite sulphur and nitrogen in the GO has been reduced to less than 50 ppm and 1 ppm respectively. The reason for higher density would be due to higher aromatic content in the hydrotreated product obtained from CAT-E. This indicates…

You already know your pool has a pump, but do you really know what that pump actually does? You might be surprised! What Exactly Does a Pool Pump Do? Your pool pump is the heart of your pool and without it, it would die...so to speak. Just like a human heart, your pool's heart (the pump) only has one thing it has to do which is pump water. However, that one thing serves several very important functions, such as: • Pulls the water from your pool through the skimmers and drains. • Then it…

The synthesis of Aa-g-poly(MAA) involve the optimization of various reaction conditions like initiator concentration, monomer concentration, crosslinker concentration, solvent concentration and pH. After the optimization of various reaction parameters the replications were carried-out in triplicates for the reproducibility of the results and statistical of the results obtained. It was performed using the Statistical Package for Social Science (SPSS) version 10. Statistical results of the…
