Bigel : An innovative drug delivery system
Bigel is a promising drug delivery system that modifies the pharmacotherapeutic characteristics of knowing active pharmaceutical ingredient (API).It is a mix between hydrogel and organogel (oleogel). The objective of the present work demonstrates the ability of bigel to overcome the disadvan- tages of both types of gels, including the limited ability to cross lipophilic barriers of the skin for hydrogels and the low patient compliance for organogels due to their stickiness and oily residues. Materials andmethods : Carbomer934, PolyvinylpyrrolidoneK 90 and Castor oil where mixed in a high shear mixer using diferent weight percentages of each. Hence,13 for mulations (BG1 to BG13) prepared by simplex mixture design modelis used to study the inuenceofafore- mentioned ingredients on appearance, dynamicviscosity, pH, stability, microscopicstructure of bigel and to understand the chemical interactions between bigel components, Fouriertrans- form infrared (FTIR) analysis will bereported.
Assessing Climate Change : Temperatures, Solar Radiation, and Heat Balance
The chapters of the book attempt to answer a number of essential questions in relation to global warming and climate change. He begins by showing how the earth’s climate has varied in the past, discussing ice ages, the Holocene period since the end of the last ice age, particularly during the past 1000 years. He investigates the reliability of "proxies" for historical temperatures and assesses the hockey stick version of global temperatures for the past millennium. To do this effectively he looks carefully at how well near surface temperatures of land and ocean on earth have been monitored during the past 100 years or more, and looks at the utility and significance of a single global average temperature
Ane's Encyclopedic Dictionary of General & Applied Entomology
Keeping the requirements of teachers and researchers in mind, this encyclopedic dictionary presents the terminology in entomology and pest management in the most authentic and comprehensive way. It also includes terms related to the close relatives of insects, such as mites and ticks and some other organisms which are pests of crops.
Algorithms for Sensor and Ad Hoc Networks : Advanced Lectures
Thousands of mini computers (comparable to a stick of chewing gum in size), equipped with sensors, are deployed in some terrain or other. After activation the sensors form a self-organized network and provide data, for example about a forthcoming earthquake. The trend towards wireless communication increasingly affects electronic devices in almost every sphere of life. Conventional wireless networks rely on infrastructure such as base stations; mobile devices interact with these base stations in a client/server fashion. In contrast, current research is focusing on networks that are completely unstructured, but are nevertheless able to communicate (via several hops) with each other, despite the low coverage of their antennas. Such systems are called sensor or ad hoc networks, depending on the point of view and the application. Wireless ad hoc and sensor networks have gained an incredible research momentum. Computer scientists and engineers of all flavors are embracing the area. Sensor networks have been adopted by researchers in many fields: from hardware technology to operating systems, from antenna design to databases, from information theory to networking, from graph theory to computational geometry.
A commercial tower in Damascus
The project is the Vietnam commercial tower in Damascus. It consists of two basements the first a shelter & tanks & a parking garage. The second ticket sales offices & shipping office & control center & room (generators, air conditioning, and filters) It consists of a ground, first, second and third floor.
18 Unconventional Essays on the Nature of Mathematics
This essays edited by Reuben Hersh contains frank facts and opinions from leading mathematicians, philosophers, sociologists, cognitive scientists, and even an anthropologist. Each essay provides a challenging and thought-provoking look at recent advances in the philosophy of mathematics, demonstrating the possibilities of thinking fresh, sticking close to actual practice, and fearlessly letting go of standard shibboleths.
