cracking during copper GTA welding. (I). Free crystalline region The actual line of S-L is lower compared with its corresponding theoretical line because of the influence of under cooling and low-melting eutectic. The α-Cu is crystallized from the liquids when the welding pool cools down the actual line of S-L. In this region, the size of α-Cu is smaller and the quantity of α-Cu is fewer. These smaller…

whether different colour tones of red and green affected sweetness perception. An experimental design was engaged where 95 first-year Psychology students voluntarily sampled four 20mL coloured liquids and rated their sweetness on a scale of 1-10, with 1 being no sweetness distinguished and 10 where the liquid was extremely sweet. The major results indicated that light red samples were perceived sweeter than dark red, and that light green samples were perceived sweeter than dark green. It was…

mixture of micronized flavonoid glycosides consisting of 450 mg of diosmin and flavonoid extract equivalent to 50 mg of hesperidin) were powdered, and sonicated at 30°C with 90 mL of methanol/DMSO (1:1) for 30 min. A bioanalytical method involving liquid-liquid extraction of diosmin from plasma samples was developed by Campanero M A et al. Plasma samples were incubated with β- glucuronidase/sulfatase to release diosmetin from its glucuronic acids conjugate. The analytes were…

Simple distillation was used for a liquid whose boiling points is 25 degrees Celsius over the other liquid, whereas fractional distillation is used for liquids with boiling points that are closer than 25 degrees Celsius apart. To obtain the highest percent ethanol, fraction distillation is proven to be the most effective. Because the 2 liquids have a boiling point difference of about 25 degrees Celsius, we used both simple and fractional distillation to remove the ethanol from the water.…

The amount of nicotine in the liquid varies. If you smoke a pack of cigarettes a day, the recommended amount for an e-cigarette would be 18-24 milligram liquid. You can gradually cut down, eventually using a zero milligrams liquid. At this point, you will no longer be addicted to the nicotine, making quitting much easier. However, Nicotine is not the only factor when it comes to…

Introduction Aspergillus is a saprophytic ubiquitous fungi genus, which includes more than 200 species. This genus have positive and negative impact to human being. Some species of Aspergillus have pharmaceutical applications, but at same time, this genus could be pathogen of respiratory diseases, and also it could synthesys potent carcinogens. The most pathogenic specie of Aspergillus for human is A. fumigatus, which causes a wide range of sickness, depending to the immunological system of…

always fascinated people of the Earth. The tiny planet always manages to intrigue scientists and if the latest report is anything to go by, one can only say that Pluto is peculiar to the core. Scientists are saying that the planet may have hosted liquids on its surface within the last million years. The fact was stated in a report which was tabled at the Lunar and Planetary Science Conference on Monday, March 21. It said that the finding is quite shocking because the average temperatures…

On September 12, 2017 at approximately 1:00 p.m., Buffy Guthrie, Case Manager III, was alerted verbally and through the smoke alarm system that there was a possible fire in the B-Unit, dorm 1 bathroom. At approximately Case Manager Buffy Guthrie notified Central Control and ran to the office, grabbing a fire extinguisher. Evacuation procedures were initiated for A and B Units by Central Control. Sergeant Matt Foreman responded to the report of smoke on the unit. Arriving to the unit he located…

Mercury is a deadly liquid that causes damage to the nervous system. If that doesn’t interest you, i'm not really sure what will. Mercury has been the interest of people for over a millennia, as a heavy liquid metal. Due to the toxicity of the element it is slowly being used less and less. Now it is mostly used in the industry as a stimulus, also used in electrical switches, thermometers, barometers and the other scientific instruments. On a biological role mercury has no role but is present in…

way of delivering nicotine and flavorings in a presumably harmless way. An E cigarette is a simple device that typically uses a 3.7V battery, a small wire coil around a wick, and e-liquid or e-juice to create a nicotine and flavor containing vapor to the user just as a conventional cigarette would. E juice and E liquid are generally composed of four main ingredients, Propylene Glycol (PG), Vegetable Glycerin (VG), nicotine, and flavorings. E-cigs, vape…
