Matthew Brayton Physics Measuring Lab Report: Purpose: To practice measuring, calculating uncertainty, and creating data tables. In this lab we measured 5 things - The surface area of the top of the one table, the volume of the room in square meters, the width of a single piece of paper, the length of my foot, and the circumference of my head. Data Table for the surface area of the top of one table: Length l /cm +/-

This drug treats breast, ovarian, pancreatic, lung, and bladder cancer. When cells are not working correctly in the body this causes a problem, the cells start to mutate and things start happening to the body, such as cancer. The chemical formula and structure for Gemzar. The chemical formula for Gemzar is C9H11F2N3O4. The chemical structure for Gemcitabine

Throughout the mixing process, the clear red solution slowly changes to a denser red solution (Appendix figure 23). A thermometer was used for temperature checking. The beaker was removed from the hot plate when the temperature was found to be higher than 50 ℃. This was done to prevent a sudden gelation happen before all the active dissolved in the ethylene glycol. Moderate heating of the solution for a period of time is allowed to obtain a wet gel (Appendix figure 24).

Liquisolid compacts: Means the formulation of immediate or sustained release dosage forms( tablets or capsules), formulated with addition of suitable excipient required for tabletting; like lubricants, binders or disintegrants.. 2. Liquisolid microsystem: Relies on a recent model which utilize same method used for formulation of liquisolid compacts combines with the addition of additives (e.g. poly vinyl pyrrolidone (PVP) in the non volatile liquid which is then incorporated into the carrier and coating materials to make a suitably flowing blend for encapsulation). Liquisolid microsystem offers advantage of that the size of the unit product may be reduced as much as 5 times lower than that of liquisolid systems and conventional products. Liquisolid systems (LS) may be classified into 3 subgroups, depending on the type of liquid medication that

1.Introduction: Ox diazole, a heterocycles nucleus has attracted a wide attention of the chemist in search for new therapeutic molecules. Five member heterocycles compounds show various type of biological activities among than 2,5-distributed 1,3,4-ox diazole are associated with diverse biological activities [2]. Various biological activities like antimicrobial, anti-tubercular, anti-inflammatory, Anticonvulsant [3], Hypnotic , Anesthetic activity [4]. 1,3,4-ox diazole showed antibacterial properties similar to those of well known sulfonamide drugs. The ox diazole nucleus with N=C-S linkage exhibits a large number of pharmacological activities [5].

% Drug content of all the formulations was determined and was found to have a range of 98-100% when UV-Spectrophotometer is used. This shows that drug was dispersed homogenously throughout the gels. The drug content for F13 formulation was found to be higher because of the optimum ethanol concentration. Rheological Studies of the
