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

Extract Preparation Several samples of Agaricus bisporus were dissected into their various anatomical components (see Figure 1.) 9.1248 g of the lower stem (S2) was collected and frozen with liquid nitrogen. The frozen sample was ground up and mixed with 28.9 mL ± 0.1 mL of a sodium phosphate buffer (50 mM‚ pH 6.5). The mixture was then transferred into a centrifuge tube and placed in a Beckman Coulter Avanti J-26 XPI high speed centrifuge. The sample was spun at 20‚000 rcf for 20 minutes at 4

Chapter I. BACKGROUND OF THE STUDY Charcoal one of the earliest known forms of ink‚ was used as early as 30‚000 BC. The first of its use documented in the continent of Europe. It may be a bit primitive to these modern times but still very useable for those who want to try it. The recipe of making it however is similar to those inks made by ancient civilizations such as the ink used by the Ancient Egyptians. We propose to make charcoal ink as a statement to increase of those in the Philippines who

There are many chemicals in our world that are soluble‚ however‚ these chemicals have to follow a set of rules to determine how soluble each chemical is and if it is at all. This is what we call solubility laws. These laws show what chemicals are soluble and which ones are insoluble. They also describe what chemicals can be dissolved and what chemicals cannot dissolve. These chemicals are them recorded on Solubility tables which list solubility and how soluble the chemicals are. According to Busch

Blessing is a poem by Imtiaz Dharker and is set in a village in Pakistan. This is a descriptive poem‚ which uses imagery to illustrate sights and sounds‚ and creates an atmosphere of frantic joy. The poem also consists of some inconsistent usage of end-rhyme‚ followed by some usage of metaphors‚ personification‚ simile‚ assonance and alliteration. The poet uses free verse in this poem to emphasize what the poem is about and to make the reader think about the situation and to think about the words

HIGH OIL PILFERAGE Rossly : Good point Rosmee. Well done. You have done a very good job. Rossly : So have you find any solution regarding high oil pilferage that we are facing right now? Any information about what I ask you to find last week? Rosmee : Yes sir. I have done a research for that. But before that‚ let me highlight once again about the problems. Currently‚ our tankers are missing and not arrived at the destination‚ our palm oils’ quality is compromised and because of our bad performance
