of the trials treated with 1.0mL fertilizer will be higher than those treated with 0.5mL or 0.0mL. Although wastewaters contain elements which are vital for the Spirulina growth, as it contain other unknown substances as well, its influence on the rate of growth of the Spirulina's cannot be unambiguously hypothesized. Since bicarbonate and sodium carbonate were not added to the effluent water but only to the portable water, it is assumed that the higher concentration of the…

Chemical thermodynamics is the study of the interrelation of heat and work with chemical reactions or with physical changes of state within the confines of the laws of thermodynamics. It involves not only laboratory measurements of various thermodynamic properties, but also the application of mathematical methods to the study of chemical questions and the spontaneity of processes. The structure of chemical thermodynamics is based on the first two laws of thermodynamics. Starting from the first…

internationally. Short staffing can lead to dangers like medication errors, falls, pressure ulcers, increased mortality rates, and nurse burn out. Three studies will be discussed in this paper pertaining to nurse- to-patient…

unconventional monetary policy in which a central bank purchases government securities or other securities from the market in order to lower interest rates and increase money supply. In short, in times when standard monetary policy has become useless, this is used by central banks to help stimulate the economy. Quantitative easing is used when short-term interest rates are close to that of zero, and no new money is needed to be printed in the process. This is used to increase an institutions…

interest rates which is used within central banks. Central Banks are a government institution that has responsibility for the amount of money and credit supplied in the economy as a whole. • United States and European bonds are becoming a safer option while interest rates in China are just beginning to cut interest rates. Low global bond rates are making bonds in the US more attractive because they’re on a higher yield. • The United States government bonds have risen since global interest rates…

has on most users is that it causes increased heart rate. A normal person 's heart rate is seventy to eighty beats per minute, when someone uses marijuana their heart rate increases between twenty and fifty more beats per minute. In some cases it has been proven that users heart rates have even doubled. When a persons’ heart rate increases the rest of their body has to work that much harder to keep up with the increased rate. This faster rate puts people at a much greater risk for heart…

The Kinetic Molecular Theory explains why gases behave the way they do. It explains how gas particles are in constant motion and create collisions that results in pressure. The theory is split up into four different postulates. Number one explains how gases are made up of tiny particles. To prove that those particles take up space, postulate #2 tells us that the particles collide with each other and those collisions make pressure. Pressure can either expand or shrink a flexible container,…

- The purpose of the Electrocardiogram test is to monitor and measure the quantity and quality of the electrical rhythm of the heart. Understanding the electrical rhythms of the heart is important because your heart's electrical system controls the timing of your heartbeat and you would have to understand how the electrical rhythm of the heart should be to know what problems may be occurring. There are three common variables that are encountered in an electrocardiogram which are the direction…

There are small particles in the air called aerosols. They are found in fog and smoke. These particles become larger in size if two processes occur. The first process is water vapor accumulating onto a particle. The next process is cool, rising air supporting the particle. Once the aerosol particles are large enough, they become cloud droplets that will have a different mechanism of growing. Cloud droplets grow differently because they are larger in size. Instead, they grow by a new process…

For our diffusion experiment our group decided to work with salt water and gummy bears. Our experiment tested the weight of the gummy bears per salt dilutions. Our tests included 1g 2.5g 5g, 1.5g, and 10g of salt diluted with water. We knew that the higher the concentration of salt diluted into the water the heavier the diffused gummy bear would be, therefore we measure weight as our numerical data. My hypothesis was that the 10g dilution of salt would have the gummy bear with the largest…
