Fast dissolving oral film‚a new kind of drug delivery system‚ is a stamp-style drug loaded polymer film with rapid disintegration and dissolution in the saliva ‚self‑administration without water or chewing. It offers higher compliance against swallowing difficulty of conventional solid dosage form‚especially suitable for patients who have fear of choking such as pediatric and geriatric patients. However‚fast dissolving oral film is not suitable for poorly soluble drug because of the grittiness taste

Paragraph 1 FePO4 is distinct from other α-quartz isotypes because its A cation is a transition metal. It is studied at different temperature ranged from 294K to 1073K by neutron powder diffraction. At relatively low temperature‚ it adopts the structure of α-quartz‚ which is tetrahedral and shown below. At high pressures‚ a phase change occurs to a more dense octahedral structure‚ which is known as β-phase. The transition temperature is 980K. During the first-order transition‚ discontinuities

Stealth technology Stealth technology also termed LO technology (low observable technology) is a sub-discipline of military tactics and passive electronic countermeasures‚ which cover a range of techniques used with personnel‚ aircraft‚ ships‚ submarines‚ missiles and satellites to make them less visible (ideally invisible) to radar‚ infrared‚ sonar and other detection methods. It corresponds to camouflage for these parts of the electromagnetic spectrum. Designers develop a particular shape

(Table 2). The deposition time for all samples was about 90 minutes. Figure 1. Schematic diagram of the magnetron sputtering system A TE-SCAN MIRA3 field emission scanning electron microscopy (FESEM) was applied to characterize films. An X-ray diffraction (XRD) was utilized using a Philips X’Pert MPD system to study the structure of the deposited film. The films adhesion was measured through a micro scratch test using a Rockwell C diamond indenter with the tip angle of 120˚ and 200 µm radius. Applied

A force can do one of four things to an object: 1. Make it speed up - accelerate. 2. Make it slow down - decelerate. 3. Change its direction. 4. Change its shape. If something is doing one of these four things there must be net force acting upon it. Newton’s First Law ’Every body continues in a state of rest or uniform motion unless acted upon by an external force.’ Something without net force acting on it will either stay still or move at a constant speed in a straight line until

source of chitosan. The water binding capacity (500%) and fat binding capacity (396%) of prepared chitosan are good agreement with the commercial chitosan. FT-IR spectra gave characteristics bands of –NH2 at 3431cm-1 and carbonyl at 1661cm-1. X-ray diffraction (XRD) patterns also indicated two characteristics crystalline peaks approximately at 10° and 20° (2θ).The surface morphology was examined using scanning electron microscopy (SEM). 4|Page Preparation of Chitosan from Jazan Area Shrimp wastes
