Due to rapid urbanization and uncontrolled growth rate of population‚ solid waste management has become acute in India. The current practices of the uncontrolled dumping of waste on the outskirts of countries have created a serious environmental and public health problem where as many issues. Plastic waste which is biggest problem in waste management is recycled in India in an “unorganized” way. 60% of the plastic-waste collected and segregated gets recycled back into materials for further processing

9Steps to Babysitting an Infant If you’re babysitting a child in his or her first year of life and who hasn’t learned to walk yet‚ it’s not the same as taking care of a toddler or an older child. Infants are very fragile and require special attention and care. Step 1: Have a fill in form ready for the parents. It should include parent emergency contact info‚ what to feed the baby‚ the baby’s allergies‚ and other stuff you should know in case of an emergency. Step2: Make sure the baby

Cheese lab Introduction Scientists work to create new and improved versions of cheese-curdling enzymes‚ as well as to improve the yields and qualities of cheeses. Modern-day cheese makers want to produce large amounts of high-quality cheese in the most economical way. Purpose ▪ Determine which curdling agent produces cheese the fastest. ▪ Determine which curdling agent produces the most cheese. ▪ Examine numerical data to support predictions. ▪ Examine variables that can

Laboratory 9 Lab title: Conductivity of solutions and Household Items PURPOSE: To understand the compounds that dissociate (break into ions) when dissolved in water. Determine ionic compounds are electrolytes. To identify solutions as electrolytic and non-electrolytic‚ and to identify variations in conductivity among electrolytes. Substances that are capable of conducting an electric current in solution are known as electrolytes. Substances that do not conduct an electric current

Lab 5 The Diffraction Grating Chinua McDonald Objective: To measure the wavelength of light with a diffraction grating. Theory: The two types of diffraction gratings are the transmission and reflection gratings. They are made by ruling on a piece of glass or metal a number of evenly spaced lines with a fine diamond point. Diffraction phenomena can be analyzed in terms of Huygens’ principle‚ according to which every point on the wave front of a wave should be considered as a source

n this lab experiment factors that affected solubility are temperature‚ liquids‚ concentration‚ pressure‚ polarity‚ and molecule. In this experiment we use temperature‚ centrifuge‚ and concentration solutions to be able to achieve the results that we wanted. Step one of the experiment was to mix HCl‚ to cause a precipitation form‚ after that we had to decant the solution‚ then we used a centrifuged to separate the the precipitate of the supernatant liquid. After the decant was done‚ then the process

Effects of different liquids on the elasticity of a rubber band Luke lash and Charles baker Question: If we submerge rubber bands in different liquid substances‚ will its elasticity of the rubber bands increase? Hypothesis: If we use a more acidic substance like vinegar‚ then elasticity of the rubber band will increase. Background: We are conducting this experiment because although it has been done before‚ the substances that have been used before are generally ordinary. Others have used hot

of the specialized underlying structures of these life-forms. In order for us to appreciate these special adaptation‚ we first need to know how a typical plant or an animal cell organelle behaves in different water and solute concentrations. In this lab‚ we will determine the effects of hypertonic‚ isotonic and hypotonic solutions on plant and animal cells. In general when an animals cell’s placed in hypertonic solution it shrivels; a plant cell on the other hand undergoes plasmolysis. When an animal

Abstract The article describes a technique for processing liquid radioactive waste water using membrane techniques to single out only radioactive waste components without affecting the salt ballast. This solution dramatically reduces the amount of radioactive concentrates to be long-term storage‚ and provides an opportunity to re-use treated water and chemicals. Keywords. Liquid radioactive waste‚ radioactive waste water purification‚ reverse osmosis‚ selective extraction of radionuclides. Introduction
