human survival. If there is no energy, our world will be drown in the endless darkness; if there is no energy, human beings cannot get over the cold winter, as well as hot summer; if there is no energy, all the modern vehicles will lose the source of power, human beings cannot move fast between different districts around the world. Therefore, the development and utilization of energy is under consideration by every country around the world, and China is not an exception. As we all know that…

PICOT For nurses at the Clinica Las Mercedes caring for adult Hispanic diabetic patients does the implementation of the Chronic Care Model (CCM) with Diabetic Self-management Education (DSME) program lead to improved diabetes management and self-care knowledge in eight weeks? 1. Sample The study will be conducted in a major primary care facility, which is chosen based on convenience. All the registered nurses in the hospital’s medical and surgical wards comprise the target population. The study…

Wind turbines, both single and arrayed, are installed in areas located onshore, near-shore, offshore and in urban areas where they are integrated with buildings. Onshore and offshore wind power industry is growing fast (Oh et al., 2013; Barthelmie et al. 2009; Lozano-Minguez et al., 2011; Hameed et al., 2011). Due to their enormous size and due to the fact that wind turbines may be subjected to extreme wind conditions during their lifetime, it is imperative that proper assessment of wind load…

What happens when the power is out and there are no more electrical devices available? It only takes a power outage to make people realize how much they depend on electricity. Currently, electricity is mainly produced by burning fossil fuels like petroleum. However, it has been widely debated whether fossil fuels were the best way to produce energy for consumers. It is arguable that alternative energy sources such as wind energy can produce better energy. Although burning petroleum is the main…

governance and in their dominant culture.” Therefore, Vidrine never would have had the power to make such an important decision if the crew and its leader did not give their consent to the expected hierarchy. So although Mr. Jimmy may not like that Vidrine thinks his crew is just there to build the well and sail away, he accepts that Vidrine has more power and decides to submit to his authority. However, Vidrine abused his power and compromised the safety of employees with the hopes of saving…

However since we have the four variables and that we’re measuring first year average scores. The formula should look like this: First year average score (%) = β0 + β1non-academic member + β2satis first-year + β3math-center + u Since first year average score is a percentage variable, it is often used in the level form as a result. So models with level-level or level-log will work best with this average score for estimating. However since we are measuring with more than two variables,…

This portion of the study discussed the estimated results of each of the specifications. The objective is to have a clear understanding of the determinants of infant mortality. Stationarity Check: Regression of a non-stationary time-series variable may cause a spurious regression or non-sense regression (a symptom of spurious regression is that the R-square value is greater that Durbin-Watson test statistics) which is not desirable. After estimating the first regression, the R-square value is…

Soil preference of the Red Compost Worms, Eisenia fetida INTRODUCTION Earthworms provide countless benefits to humans, plants and animals, by improving drainage, advancing nutrient accessibility, and providing a steady soil system, helping to develop farm production. They benefit the soil ecosystem by decomposing and recycling organic matter, opening up pores inside the soil to develop its formation and supplying food for predators . By adding nutrients to the soil they inhabit, earthworms are…

Clearly, randomization is crucial to eliminate certain bias and have an accurate trial. 6. Explain how the intervention(s) in the treatment arm differed from how participants in the control arm were treated. In other words, what is the trial testing? Participants in the treatment arm were given 12.5 milligram Zinc Sulfate, whereas the participants in the control arm were given a placebo. The trial is testing whether Zinc Sulfate is beneficial to children who have Malaria or not. 7. Was the…
