Introduction The first law of thermodynamics states that the energy of the universe is constant. Heat is transferred when the atoms of one material vibrate and collide with the atoms of another material‚ thus transferring energy. For this reason‚ heats always travel from hot to cold objects and two objects will reach an equilibrium temperature. Materials and Methods 1. Oven 7. Test Tube 2. Pasco Temperature Probe 8.

Objective: In the present study‚ an attempt was made to improve the bioavailability of Zidovudine by formulating into Orodispersible tablets‚ as it has poor bioavailability and extensive pre systemic metabolism. Methods: In the present study‚ the mucilage extracted from Fenugreek seeds (Trigonella foenum-graecum) was used as superdisintegrant. The oral dispersible tablets were prepared by using wet granulation technique. A three factor two level (23) central composite design was employed for the

Walter A. Shewhart March 18‚ 1981- March 11‚ 1967 Walter Andrew Shewhart is regarded by many as the “father of statistical quality control.” He was born in New Canton‚ Illinois on March 18‚ 1891 to Anton and Esta Barney Shewhart. Walter attained his bachelor’s and master’s from the University of Illinois in physics and graduated with is PhD from UC Berkely in 1917. Throughout his adulthood‚ he was a professor at both universities and ran the physics department at the Wisconsin Normal School

Fashion blogs are bad Did you know that a fashion blog is actually a drug‚ well it’s not classified as a drug but you get addicted to them. You stop seeing the importance in life such as news‚ disasters and so on. All that’s on your mind is fashion‚ shoes and makeup. Fashion blogs also makes you spend money. I think fashion blogs are bad and here comes some reasons. First of all fashion blogs are only nonsense. All there is to read are clothes‚ makeup‚ bags and shoes. All their readers

Summary These experiments were conducted to find the specific heat of a metal as well as the heat of solution of a solid. Both experiments required the use of calorimetry to measure heat flow and temperature change. The specific heat of the metal was found by heating it in boiling water before transferring it to the calorimeter that was partially filled with water. After shaking the calorimeter‚ the temperature change was measured and recorded. This information was used to calculate the specific

a way society can interact with both the world of information and physical world is the “SixthSense” project. The SixthSense project is an idea started by Pranav Mistry and his associates from the Fluid Interfaces Group based out of the MIT Media lab. This organization has many projects which are all founded on a few common goals. This goal can come to fruition by focusing on innovations. These Innovations include enhancing the experience of using technology by implementing ways to make the experience

Differential Scanning Calorimetry (DSC) was carried out to investigate the thermodynamic properties of CXB‚ different carriers‚ PMs and SD preparations. Their thermograms are represented in Figures (9-14). The thermogram of CXB in Figure (9) was characterized by single‚ sharp endothermic peak at 165±0.56°C which represents the melting point of CXB. Some researchers reported that CXB melting point ranging from 160.79–164.64°C (127)‚ and Paradkar A. et al. (2002) reported that sharp endotherm corresponding
