1.0 INTRODUCTION: AISI 304L austenitic stainless steel is widely used as engineering materials due to its high strength and good corrosion resistance properties. However‚ AISI 304L stainless steel undergoes extensive wear and erosion when applied as components in aggressive environments such as petro- chemical and marine atmosphere [1]. Solid particle erosion is defined as the progressive loss of material from a solid surface due to mechanical interaction between the surface and some fluid entrained

Introduction The Family Centered Care model‚ according to the ANA (2008)‚ acknowledges the family as the main constant in the child’s life and as being critical in the child’s plan of care. There are eight elements of family centered care‚ and together they advocate appreciating each family’s unique strengths and challenges‚ recognizing the importance of the family in planning and providing care‚ and providing collaborative care. According to Smith‚ Swallow & Coyne (2015)‚ family centered care can

Report on Zinc deficiencies Zinc deficiency is the inadequate amount of zinc in the body to meet its demands. Zinc is vital to the body functions such as‚ a healthy immune system and wrongdiagnosis.com states is best known for minimizing the effects of the common cold or upper respiratory infections. It can enhance the functions of the liver‚ muscles and bones. Other functions of zinc in the body are to wound heals; aid enzyme activity; DNA production and cell division.

The purpose of this lab was to find out the reaction of iron nails and CuSO4‚ copper sulfate solution. Before starting the experiment‚ there were two possible outcomes of the reactions. CuSO4 + Fe → FeSO4 + Cu or 3CuSo4 + 2Fe → Fe2(SO4)3 + 3Cu. The ion chart showed that iron can only make two charges‚ +2 and +3. As the liquid evaporated‚ the weight changed because the liquid added to the nail’s weight. In a real world situation‚ scientists can use ratios to determine how much of a substance that

Copper has been used in cookware because of its good thermal conductivity. In Eastern and Western cooking traditions‚ copper cookware sets were popular because they provided the best conductivity‚ and therefore the most even heating and cooking. Copper pots and pans were a staple of the colonial kitchen and have withstood the test of time to remain popular in the professional and home kitchen alike. Copper cookware sets will typically include a saut� pan‚ frying pan and a sauce pan. These are essential

ability to identify metals is an extremely important one. With this ability‚ we can correctly assign different traits‚ and use the metal in its most suitable environment. This is important to many industries‚ where metals play an increasingly large role. Determining the identity of the metal is paramount to determining what conditions to use the metal under. This seemly simple task is‚ however‚ can be quite complex‚ as there are many ways by which one can identify a metal‚ each with varying amounts

KINETIC STUDY OF LIQUID-PHASE ADSORPTIVE REMOVAL OF HEAVY METAL IONS BY ALMOND TREE (TERMINALIA CATAPPA L.) LEAVES WASTE ABSTRACT. The kinetic sorption of five metal ions - Al3+‚ Cr6*‚ Zn2+‚ Ag+ and Mn2+ - from aqueous solution onto almond tree leaves (ATL) waste in single component system has been studied. The experimental data was analyzed in terms of intraparticle diffusion and rate of adsorption‚ thus comparing transport mechanism and chemical sorption processes. The sorption rates based on
