Its evaluation is desirable during pre-formulation studies if the drug constitutes the major portion of the dosage form. Only one form of the polymorphic compound is thermodynamically active at a given temperature and pressure. Techniques for investigation for the stable form of polymorphs are microscopy (hot stage microscopy, X-ray diffraction, IR spectrophotometer, thermal analysis and dilalometry.(Brittain,2009) THERMAL ANALYSIS It is the branch of science that deals with the properties of material that change with temperature. For the measurement of such properties various methods are used. the techniques all follow the change of specific physical property by the change of temperature or time in the specifically controlled environment, since moisture and temperature are the basic factors effecting the stability of the pharmaceutical compounds thus we take temperature to measure various parameters.(Menczel,2009) Thermal analysis Instrumental technique for describing various properties General method Acronym Property measured Application Differential scanning calorimetry DSC ?T, differential power input Measurement of kinetics Differential thermal analysis DTA ?T chemistry, pharmaceuticals, polymers Thermo- gravimetric Analysis TGA Mass composition, extent of cure, stability Thermo-mechanical Analysis TMA Length or volume Shear and torsion modulus of films, fibers, laminates adhesives Dynamic mechanical Analysis DMA Viscoelastic properties rheological properties Dielectric Analysis DEA Dielectric properties isothermal crystallization Nano/micro-thermal Analysis n-TA Penetration, ?T Surface properties of solid dosage form THERMAL ANALYSIS OF PHARMACEUTICAL MATERIALS AND POLYMERS Techniques such as DSC, TG can investigate the transformation during polymorphic conversion.TGA is often used to measure residual solvents and moisture and solubility of the active materials in solvents.

IAQ & Thermal Comfort
...? Indoor air quality and Thermal comfort Indoor air quality and Thermal comfort Thermal comfort and indoor air quality are considered amongst important factors when considering the quality of indoor environment. These factors are usually given much attention when designing buildings and structures in places that experience extreme variations in environmental conditions (Amissah, 2005). Examples of these areas include areas that experience low and/or high temperatures variations, and areas in which the quality of air is compromised (areas in which air is polluted, among other factors that interfere with the quality of air that humans breathe) among others (Al-ajmi, 2010). Both regional and...

Nano- and Micro-Technology
...Introduction to Nano- and Micro-Technology The word nano finds its origin from Greek, meaning midget. It de s a billionth part (i.e. 10-9). Similarly a nanometer (nm) is one billionth part of a meter. Nanotechnology, as the name suggests is the use of technology on nano-meter scale. It is an emerging field of possibilities for the humanity. It is essentially the engineering of functional systems at the molecular scale. It involves, penetrating down the nano-scale level i.e. one billionth of a meter or 1/100,000 the width of a human hair. The concept picked up when Richard Feynman in one of his talks way back in 1959 mentioned the progress made by science in the field of...

...NanoGene Technologies, Inc. a. Evaluate the founder’s decisions regarding the split of equity and compensation level. The founders of NanoGene Technologies, Inc have made important decisions about the way the equity in the company is split and the compensation level of the company founders. The decision to equally split the equity is the fairest but not the wisest. Just because the five men are founders does not mean that they all should share in the same equity. Each founder holds a different position and deserves different equity and compensation. It is likely that the decision was chosen to keep fairness between the founders. When closely looking at the job duties and responsibilities, it is obvious that the equity... Technologies, Inc. a. ...

Solar Thermal Energy
...Solar Thermal Energy Introduction During our physics lesson, we learn that there are good or bad conductors of heat. Also, aspects such as expansion and contraction are addressed. Usually, heat is a topic that is prevalent in physical sciences. But what is heat? Heat should not be confused with temperature. Heat can be described as the transfer of energy from an object that is at a higher temperature to an object at a lower temperature. A body does not possess heat. Instead, it possesses internal energy. This brings about the aspect of heat transfer. Heat energy is finding application in meeting crucial aspects of global needs. This is the aspect of meeting energy needs through the use of renewable energy. One such...

Thermal Solar Energy
...Thermal solar energy due: Table of Contents Table of Contents 2 Introduction 3 Introduction Nowadays, the primary energy origin is natural gas, biomass, oil, and coal. There are other forms of energy sources that include nuclear power got from thermal energy preserved in the interior of the earth and radioactive substances. They have been used for long and are known as non-renewable energy. The challenge is that the sources of the non-renewable energy are rapidly exhausting and are not able to satisfy the future demand of energy (Rathore, 2010). The non-renewable sources of energy are expensive because they are obtained at clear-cut prices. They are dangerous to the habitat, and the concentration of power...

...and Wang 2011). Theoretically, the ability to construct multiple devices that maintain components of nano-scale would make it feasible to install, literally, billions of different minute-size transistors onto only a single chip that are able to operate at gigahertz frequencies (Drexler). Such chips represent the physical technology of nano-tech that have the capability of producing valuable information machinery. It was in the early 2000s that the functionality and opportunities of nanotechnology came into the forefront of the scientific community consciousness. In the year 2000, American President Bill Clinton enacted the National Nanotechnology Initiative which provided federal funding for...
