ethanol+30ml of chloroform+10 a. acetic/100ml) 10% hydrochloric acid Carmín Aceto (acetic acid (45%) + carmine red (dye)) Methodology Five to eight days before the practice the onion is prepared. First, a scraping with a blade is made by eliminating the dry or dead roots that are at the base of the bulb. In a bottle with water place the onion (annex. Fig. 1). Keep the base of the wet onion and change the water of the container every 24h. When the roots reach 3 cm long, remove the onion from the bottle and execute a root cut at the last centimeter of the tip. Place the roots in the Petri box with carnoy fixing solution for 20 minutes. After 20 min place them in 10% hydrochloric acid for 10...

Hemaglutinine: It is a membrane protein found in the flu virus that allows it to locate and infect host cells (8). Is clearly differentiated by Two different parts, the tail, which is located inside the membrane and a globular head, which contain the different antigens and receptors necessary for their mechanism of action. Its structure was resolved in 1981 by Wilson et al. To crystallize this protein, a proteolysis of the Hidrosoluble region was carried out. The inconvenience of this method is that it cannot be crystallized and therefore solve the...
ethanol, which are significant sources of revenue for the country ("Brazil Ethanol"). Most of the vehicles and machines use ethanol since it is a cheaper source of energy and it does not emit carbon into the atmosphere. As a source for sugar and clean source of energy, it is a good idea for the country to continue sowing sugarcane. However, the country should not go to the extent of cutting down the forest just to plant sugarcane. Such an action is likely to obliterate the environment and may lead to harsh climatic conditions around the country that will not be suitable for agriculture ("The Amazon: Earth's Largest Rainforest"). Do you think you can regenerate the environment and prevent pollution...

ethanol used (i.e. 300 mg/kg body weight) and also used the peroxidase method in galactose analysis since it was the method conducive in the University Central Hospital of Helsinki laboratory. To recant on the amount of the ethanol used in the LTTE, it had been revealed that smaller amounts of ethanol are usually linked to accurate results as compared to larger ones. After delivery of the samples using a thermostat to the laboratory, the interpretation of the results on the LTTE was regarding the optimal rise in both blood galactose and glucose. The main standards used to detect an escalation in blood glucose was set at 1.1mmol/l or even higher whereas the gold standard for the maximum rise in...

ethanol, methanol, diethyl ether and dimethylformamide) and they were used as supplied. Synthesis of the Schiff Base Ligand The ligand was synthesized through the addition of 1-ethanone (QSE) (3.15 g, 20 mmol) that dissolved in hot absolute ethanol (30 mL) to Cyanoacetohydrazide (CAH) (7.04 g, 40 mmol) in outright ethanol (30 mL). The reaction that resulted from the mixture was heated under reflux for 4 hours. Consequently, the orange crystals were sieved, cleaned with ethanol and then air dried in an open atmosphere. Recrystallization was used in obtaining fine crystals from ethanol, and the ligand was kept in a desiccator until used. Equally, the yield obtained was 3.96 g (88 %), m.p. 207-209C....
