amount of zinc in vitamin water had to be determined. To do this, three methods were applied. The first was by a calibration plot method, where zinc standards were prepared and from the absorbance of those standards a calibration curve was plotted, which in turn was used to determine the amount of zinc in vitamin water. The second method was standard addition. For this method, an un-spiked and spiked solution were prepared. The un-spiked solution only contained the vitamin water, while the…

Water is one of the most important and essential fluid to our human body. We use and drink water almost 24 hours a day and 365 days a year, however, many of us probably have never thought of and find out what are the chemical and scientific reasons behind the importance of water. Approximately 50-65% of the average adult human body is water, however, this varies based on a number of factors such as age, health, weight and sex. In males, it is normally about 60% of the body weight. In…

if approved. Native Americans argue that the proposed pipeline will damage their vital water sources and affect the whole reserve, making their water undrinkable and harming their health. Crude oil pipelines, usually buried underground, can easily contaminate water (“How Can You Identify Pipeline.”), which in turn toxifies the water sources communities rely on for consumption and daily life (Harris, Robbie). Water is the liquid of life, and they should be prioritized; however, unfortunately, oil…

Research objective 3: Evaluating the coastal vulnerability to sea level rise and hurricane for the coupled human and nature system under consistent or even increasing urban growth process. Question 3.1: How to define the vulnerability in the coupled human and nature system? Based on the vulnerability conceptual framework in Turner (2007), three general components, namely exposure, sensitivity and resilience are considered. With the first two components considered separately for nature and human…

types of Vertical Column PBRs. Illustration "B" is an example of an "Internal Loop Airlift" PBR [7]. The "Internal Loop Airlift" PBR works similarly to the Bubble Column as the gas enters the column through the bottom and leaves through the…

The water moccasin, North America's only venomous water snake, has a distinctive blocky, triangular head; a thick body; and a dangerous bite. Common names include variants on water moccasin, swamp moccasin, black moccasin, cottonmouth, gapper, or simply viper.Water Moccasins reach 30 to 48 inches, occasionally up to 74 inches. The back is dark olive or black, the belly is paler. The snout is always pale, and there is usually a dark vertical line by each nostril.Water Moccasins are primarily…

Literature Review Temperature The greatest source of heat in water is solar irradiance by direct absorption (Wetzel and Likens, 2000). We might assumed that heat will remain at where it was absorbed and temperature will decrease exponentially with depth, just with the light and may remain constant at the hypolimnion (Lampert and Sommer, 2007). Water has the properties of high heat capacity, thus the larger lake might tends to moderate the local climate and provide the longer growing season for…

Introduction: Tea is the most widely consumed drink (other than water) on a global scale (Jacobs, 2014). Generally served just below 100 degrees Celsius, issues such as heat transfer limit the appreciation of the beverage. The thermal energy in tea is defined by the movement or kinetic energy of the particles within the tea, hence, a decrease in the movement of the particles reduces the temperature. The thermal energy in the tea is lowered via means of energy transfer through convection,…

Starfish move using a water vascular system. Water comes into the system via the madreporite. It is then circulated from the stone canal to the ring canal and into the radial canals. The madreporite is a rounded plate on the aboral surface of the central disc in inter-radial position. Its surface bears a number of narrow, straight or wavy grooves or furrows. Each furrow contains many minute pores at its bottom. Each pore leads into a very short, fine, tubular pore-canal. The pore-canals unite…

Only one item was used; therefore, it was impossible to know if the experiment had internal reliability. Nevertheless, there existed problem with the cold pressor test. A study had shown that due to the differences in the temperature of the ice water, the test lack standardization (Mitchell, 2004). In the MythsBuster experiment, the participants all put their hand in the same ice bowl, and the water was described as slightly above freezing temperature. Since the ice melted in contact with…
