third type of colloidal system. Association colloids are micro heterogeneous system, here the particles of the colloidal dispersed phase formed agglomeration of molecules or ions of the substance dissolved in the dispersion medium. Amphiphile or surface active agents are characterized by two distinct region of opposing affinities with the same molecule or ion. When the liquid medium present at low concentration, the amphiphiles exist separately and the size to be subcolloidal. As a concentration…

Lo- moon. Lo is about 4.5 billion years old-same as Jupiter. Lo is the fifth moon from Jupiter. Lo is slightly larger than Earth’s moon. Lo is tidally locked, so the same side always faces Jupiter. Lo’s surface temperature averages about minus two hundred two degrees fahrenheit. But oddly enough Io's volcanos can reach to three thousand degrees fahrenheit. The interior of Lo is composed of an iron or iron sulfide core and a brown silicate outer layer. Lo…

slightly alkaline ocean into a bit less alkaline. And if continues to happen in the same way, would acidify the water and also lead to warmer oceans. From NASA earth observatory internet resource, described that since 1750, the pH of the ocean’s surface has dropped by 0.1, which is 30 percent in change of acidity. Ocean acidification cause significant biological impacts. For example the growth rate for shellfish become slower, warmer water temperatures cause coral to expel the algae living in…

adaptations that allow them to live in either land or water. A diving beetle and a mayfly are both good examples of how insects have adaptations that allow them to live in the water and be fully submerged without drowning. Diving beetles swim to the surface of the water to collect air, the gas exchange process then occurs and oxygen is produced. When the beetle swims back under the water they have a system in which they conceal the oxygen in…

political values of the Luba state. The Lukasa (memory board) was estimated to be created between the 19th and 20th century in the Democratic Republic of Congo, home of the Luba people. Although many Lukasa use shells and beads studded to the wooden surface, the wood-sculpture pictured has incised designs and carved images in the relief; however, they both still communicate historical…

airplane. It has curved surfaces designed to give required ratio of lift and drag. It helps to create different aeodynamic forces. The force perpendicular to the motion of aeofoil is lift force. The force parallel to the motion of aerofoil is drag force. 1.2 How it works? Aerofoil consists of following components: • Suction surface • Pressure surface • Leading edge • Tailing edge • Chord line Figure 1 Profile of Aerofoil Source: (Wikipedia, 2017) On suction surface high velocity of air…

Abstract. The theoretical treatment of the equilibrium structure of the derivatives was based on the DFT method using the functional B3LYP with the base 6-311 ++ G (d, p). To distinguish the molecular electrostatic potential surface (MESP), we used the principle of HSAB (Hard Soft Acid and Base), in order to have the centers of activity of a molecule and the effects of substitution on the systems of pyrazolooxazine. These have anti-inflammatory activities. In our work, we have applied methods of…

as the measurement of surface temperature by a surface mounted thermocouple as shown in Figure 5.9 (a). Figure 5. 9 : (a) Surface mounted thermocouple in Example 5. 1 (b) Thermal resistance network model Heat loss from the thermocouple is modeled as shown above by discussion leading to Equation 5.3. Thermocouple attached to the surface of a massive solid whose temperature we would like to measure. Excepting where the thermocouple has been attached the rest of the surface of the solid is…

inches, and 3 inches. According to the Demonstrative Report, 2008, corn that was planted 2-3 inches below the surface had the best results and seeds just ½ inch below had the worst. This is a little different from the experiment being tested today. The experiment being tested is when you plant Alaskan Pea seeds deeper will they grow the same height just as much as the seeds just below the surface of the soil. Germination is defined as a plant which has begun to sprout and is starting to grow…

scratches that accumulate incrementally on the surface. Canning (2012) remarks that his paintings do not aim for “flawless” surfaces; rather “they’re marked, and they do tell the story of the history of their making”. The hereditary traits of Canning’s inheritance of his father’s trade can also be seen in works like “Lithium” (Fig 4-11, 2008), and also in “Conditions of entry” (Fig 4-12, 2010), where these pocks, deep gouges and scars marring the surface are filled and rendered flawless through…
