Objective: In the present study, an attempt was made to improve the bioavailability of Zidovudine by formulating into Orodispersible tablets, as it has poor bioavailability and extensive pre systemic metabolism. Methods: In the present study, the mucilage extracted from Fenugreek seeds (Trigonella foenum-graecum) was used as superdisintegrant. The oral dispersible tablets were prepared by using wet granulation technique. A three factor two level (23) central composite design was employed for the
Surfactants are substances that are adsorbed onto the surface/interface of a system and alter the surface/interfacial energy of the same. They generally consist of two parts, hydrophobic head and hydrophilic tail. Surfactants can be classified on the basis of effect, origin, structure and applications and can be further sub classified on the basis of chemical structure as anionic, cationic, non-ionic and zwitterionic surfactants [21]. Anionic surfactants have negatively charged head group and positively
2.1. The essential elements in Business ethics According to Kenneth (2015), stated that in a business environment, the essential element in business ethics is to conduct business with integrity, honesty and all business must committed to treat all the employees and customers fairly. In contrast, an unethical business can be referred to as an act of unlawful action and morally vice activity within the business setting (Babalola ,2009). 2.2. Impacts on the Environment i. Garment industry According
The important preventive measures for the toxic chemical, spillage or pollution are as follows: Solid: Dust form – Collect dust by vacuum entrapped in cyclones or Scrubbers. Stop the dust formation in the source itself. Studies: Treat the toxic chemicals with other chemicals to form non-toxic Chemicals e.g. Hydrogen Cyanide (toxic) + Sodium Thiosulphate = Sodium Thiocyanate (non-toxic) Arsenic and its compounds are toxic. No other method is available to Change the toxic arsenic to non-toxic arsenic
Introduction 1.1 Introduction The demand of clean water has always been a major universal concern and this issue is becoming more urgent with the expectation of water deficiency to an alarming rate by the year 2025. Hence, there are needs a new technologies for desalination and wastewater treatments, to meet the requirement water demands with credible and affordable water sources. [Teoh and Chung, 2009] (1) Desalination is a process in which saline water is separated into two parts using different forms
both purely organic and genetically modified foods, drawing from studies concluded both against and in favor of both, concluding to the above mentioned. Organic food, cited in Lewin (2013), is defined by The Department for Agriculture and Rural Affairs (DEFRA) to be: ‘the product of a farming system which avoids the use of man-made fertilizers, pesticides; growth regulators and livestock feed additives. Organic agriculture is a systems approach to production that is working towards environmentally
Chapter 2 REVIEW OF RELATED LITERATURE AND STUDIES Review of Related Literature Adhesives Adhesives are capable of holding or sticking two surfaces together in a strong and often permanent bond. Adhesives may be interchangeable with glue, cement, mucilage or paste. Adhesives are typically organized by the method of adhesion. These are organized into reactive and non-reactive adhesives which refer to whether the adhesives chemically react in order to harden. (Goiler Encyclopedia of Knowledge).
physicochemical studies [2]. These proteins exhibit the interesting properties of binding to a variety of hydrophobic ligands such as fatty acids, lysolecithin, bilirubin, warfarin, tryptophan, steroids, several dyes etc. The drugs (more than 90%) like analgesics, anesthetics, tranquilizers,
tragacanth is obtained from the stem of the bush like plant “goat’s-horn”, Astragalus species. Gum tragacanth has been used commercially for well over 2000 years and is currently widely used as a thickener and emulsifier in emulsion systems in different pharmaceutical, food, cosmetic and diverse industrial uses. In addition, it is on the list of stabilizers that are permitted by Food and Agriculture Organization/ World Health Organization that could be used during the manufacture of yogurt. In Europe
The demand for industrial establishment increases due to rapid increase in population. In order to fulfil human needs, man has overexploiting the available resources, which result in the pollution of water, air and land. Although industries play a major role in the economic growth of a nation but all around the world due to rapid industrialization, pollution increases including Pakistan. Industrial effluent is one of the major way through which pollutants enters into the biosphere.Physicochemicalparameters
