In the nursing profession detailed and factual writing is key. The writing that nurses do needs to be scholarly and to the point. There are multiple different facets of writing a professional nurse can do. On the job a nurse would most likely be doing documentation style of writing. However there are also nurses who are published authors who write educational pieces for the entire nursing community. These types of editorial pieces are published in nursing journals. These articles can range…

In order to safely dispose of a solution with a pH of 12, the solution needs to be diluted with an acid to neutralize the basic solution. The pH range should be between 5 to 8 to be ready for disposal. 2. A graduated cylinder, Erlenmeyer flask, and beaker were used to measure a 60-mL volume. Which of these devices seems to be the most accurate for measuring a 60-mL volume? Be sure to explain what the term ‘accurate’ means. How did you determine this during lab? State some reasons why this…

Carlos de Sigüenza y Góngora in the 17th century, the nature of Teotihuacanos society has been a persisting mystery however, through the utilisation of archaeometry, evidence can be interpreted and lucid hypotheses formed to a significant level of accuracy. Science and archaeology have allowed the development of theories and the stimulation of valuable discussion and coalescence of historical perspectives.…

According to Simon and Farndon (2008), genetic disorders are abnormalities in an individual 's gene or set of genes which could be due to mutations in the DNA. Also, there are thousands of genetic diseases that can occur as it is estimated that the average rate of genomic mutation is about 2x10-8 per nucleotide per genome (Nachman and Crowell, 2000). Furthermore, they can be grouped into three types named single gene disorders, chromosomal disorders and multifactorial conditions (Milewicz, 2007)…

Water is an important resource needed for our subsistence & is required on a global level. The various hydrologic cycles are necessary in order to preserve the balance of our ecosystem. Thus, good quality water is necessary for our survival. Chemical & biological composition are two criteria for evaluating water quality. Water hardness can be defined by the presence of divalent cations dissolved in a water sample. The divalent cations usually present are Ca2+ & Mg2+ and these cations bestow…

Abstract Objective: Snoring and body mass index (BMI) have been previously reported to be associated with metabolic syndrome(MetS). The aim of this study is to explore the individual effects and possible interaction of snoring and BMI on MetS. Methods: A total of 3794 coal miners aged 18-65 years old were recruited from Shanxi province of China. The individual effects were assessed by multivariable logistic regression model. The interaction on an additive scale between snoring and BMI was…

A ball, and a feather dropped at the same height will hit the ground at the same time when placed in a vacuum space. This is because acceleration of motion is the same for both object, and in this experiment, we are going to calculate accelerated motion using inclined planes. In this experiment, we will see whether “distance traveled is directly proportional to the square of the time”, and “if speed of a falling object depend only on the height from which it falls”. This experiment will give us…

strength of association * Measured by the multiple correlation coefficient (coefficient of determination), R^2 * Adjusted R^2 takes the number of IV’s and sample size into account (can compare to different samples) * R^2 shows the predictive accuracy (if you can predict DV perfectly R^2 will be…

In the essay, “Stress is Bad for Your Well-Being” the authors raise the issue by asking the question, is stress harmful to our well-being. In this case, the issue they are raising is considered descriptive since it is raising a question about the accuracy of a description, in this situation being how stress can affect health. In addition, the question being asked begins with the word “Is,” which also fits the characterization of being a descriptive issue, meaning that the question requires an…
