observer variability. Suggested methods to decrease the risk of ascertainment bias when using a visual scoring system to assess hirsutism include : (i) minimizing the number of examiners , (ii) requesting the patients not use laser or electrolysis for at least 3 months, not depilate or wax for at least 4 weeks, or not to shave for at least 5 days before the exam ,(iii) examining all patients complaining of unwanted hair growth or oligo menorrhea fully, regardless of initial appearance…

CONFERENCE SESSION: SUSTAINABLE ENERGY FUTURES ENERGY STORAGE FOR ELECTRICAL GRIDS: CURRENT STATUS AND TECHNOLOGY PROSPECTS? Theologos Bamparoutsis Student Engineer School of Engineering, University of Edinburgh King’s Buildings, Edinburgh, EH9 3JL, Scotland, UK Summary A green electricity grid which will be able to meet the growing energy demand, and fulfil the network’s requirements, is one of the main goals of the energy industry, and along with renewable energy sources, electricity storage…

liquid children’s vitamins Liquid Childrens Vitamins are a great way to ensure your children get their nutritional supplementation on a daily basis. It is great for younger children who have difficulty swallowing pills or taking medicines. Instead of a hard gelatin capsule or an oversize oblong tablet. Liquid children’s vitamins is a great tasting liquid filled with all the vitamins, minerals that children need to stay well and grow up healthy and strong. Such basic things that children need,…

In the 1800s, chemist Michael Faraday discovered that water could be decomposed in an electrolytic solution into its elements. This discovery was made through the use of an electric current in a process now known as electrolysis. This was the first systematic study of electrolytic solutions (Lower, n.d.). Faraday observed that two requirements must be met in order for a sample of matter to be an electrical conductor. The first requirement is that the sample must contain electrically charged…

simpler substances while elements cannot. 21. The composition of a substance is always fixed, but the composition of a mixture can vary. 22. Chemical symbols are used to represent elements and chemical formulas are used to represent compounds. 23. Electrolysis, or the passing of an electric current through a substance, can break down a compound into simpler…

Hall’s earliest achievement was when he used a process to obtain his first sample of aluminum in his parents shed. "The process was the electrolysis of aluminum oxide dissolved in a mixture of molten cryolite and aluminum fluoride in a graphite crucible" (Craig). Hall applied for a patent and in 1886 and received it in 1889. Later that year, Hall received money from a man named Alfred E. Hunt…

Despite all the mentioned advantages, reaction of PSF with the pollutants is slow and in order to accelerate the reaction rate, catalyst is needed. The activation of persulfate are mainly carried out by electrolysis, transition metal ions, UV radiation and heat (20). Iron ion (Fe2+) is an effective catalyst is used for activating the persulfate ion reaction rate. Fe2+ stimulates the persulfate ions and produces sulfate radicals which have higher oxidation…

catalyst, it gives methane and water. CO2 + 4 H2 → CH4 + H2O This reaction can be used to produce water in empyreal. CO2can be extracted from mars and the waste from the industrial torus where there is high levels of CO2 H2 can be obtained from electrolysis The methane can be used as a fuel in industries. GRAVITY Empyreal has a torus based design because it has to rotate about its axis; when it rotates it creates artificial gravity. So the people inside would have to experience centripetal…

Life Support Systems in spacecraft. Life support systems in spacecraft, without them, astronauts won't be able to visit space. All of manned spacecraft have life support systems. In simple terms, life support systems are equipment allowing people to feel as comfortable as on Earth. Earth has an Atmosphere. The Atmosphere is the main shield on Earth. It provides breathable air, and it is responsible for comfortable climates. In space, climates are extreme, and there is a vacuum, an absence of…

thiosulfate solution. However, studies have shown that the resultant AgNO3 electrolyte is considered to be ideal for further silver recovery via electrolysis or precipitation processes is due to its high recovery performances than that of the silver thiosulfate electrolytes. AgNO3 would seem to overcome the existing problems encountered during direct electrolysis and precipitation of silver from thiosulfate electrolytes where pH and sulfite controls have usually affected the precipitation and…
