SUBJECT: Expanded Definition of Ground
The purpose of this document is to provide an elaborate explanation on a technical term that is relevant to either my major studies or future professional field of practice. In order to acquire information on my chosen term I will, thorough research, be using various academic and general audience sources. In the following paragraphs, I am to quote from those sources the several definitions that my term contains, the use in context (via etymology), the specific definition that best suits my chosen career path, as well as, offering proper citations. The technical term that I have chosen to use for this document is ground.
Through exploration, I have found that the term ground happens to be inherited from the Germanic branch of the Indo-European language consisting of German, Dutch, Gothic, etc. A few lexicons had led me to numerous definitions of the term ground. According to the Oxford English Dictionary (OED), ground (1) is defined as, “the soil of the earth” (ground, 2019). This definition can alternatively be expressed as, the surface in which all living things walk upon, as well as grow from. Another definition of ground (2), according to the OED, is defined as, “Any material surface, natural or prepared, which is taken as a basis for working upon” (ground, 2019). This definition can alternatively be expressed as, provided by an example, using a backdrop for photography or even using makeup which involves the application of a substance atop a surface as a starting foundation. A third definition of ground (3), is defined as “Reduced to fine particles by grinding or crushing” (ground, 2019). This definition can alternatively be expressed as, the energy of forcing the surfaces of two or more solid matter against one another until their physical structure changes into a powder or dust. Lastly, the fourth definition of ground (4), according to the Cambridge Dictionary, is defined as “a reason, cause, or argument” (ground, 2019). This definition can alternatively be expressed as, important topics centered around a single point in order to reach solutions.
Each definition in comparison to one another have similarities in the sense that a core, or source area must, initially, be defined followed by the implementation of matter whether from a tangible or a situational aspect. Their differences, might often, present themselves through professional occupations, on a regular day outside, or even by the act of cooking a meal. A gardener, for example, may want to plant a garden and for that to be done the ground (or soil) must be dug up. I, personally, find this version of the term used more frequent in society because it constantly surrounds life, as it is the earth. Whether on land, sea, or air, a sense of a solid surface below us always arrives to the subconscious mind. Another use of the word, ground (4), can be found within the legal system under the stand your ground law which is denoted as, according to Dictionary.com, “…[a] law that eliminates the duty to retreat by allowing, as a first response, self-defense by deadly force.” These two examples can justify just how broad the term ground is easily spread.
With research, I will be elaborating on the wide-range use of the term and providing quotations from various sources. Those quotations will allow me to discuss how the term is used in context. Context is everything that surrounds a word(s), idea, environment, etc. giving that main subject a clear and concise meaning when outputted. It is a graspable flow of understanding the bigger picture. I acquired from a New York Times article a reference example that read from the words of Odede saying, “This, perhaps, is terrorism’s fertile ground” (Odede, 2014, 23). In terms of context, I was able to gather that ground is described, metaphorically, as a place of growth. This term will be in relation to the following quotes in context. In the land of Nairobi, Kenya, there are slums (fertile ground) where terrorism is bred, and the youth would ultimately face a life growing up under the conditions of inculcated survival. Another example of my term in context is found in a blog posted by the username Shanegenziuk suggesting, “This is how you want to be recycling coffee grounds – making use of a small strip of soil under some trees will do just fine!” (Shanegenziuk, 2017). This example consists of ground (3) which is defined in the beginning of this document. Coffee grounds refer to the tiny particles that coffee beans become after being processed in a grinder. In this case, once the coffee grounds have been used, would be thrown into the soil as compost, due to their remaining nutrients, to better the environment. In relation to the previous quote, the term is described as a fertilizer. Lastly, according to Roselli, “…to increasing interest both in the introduction of ground source heat pump (GSHP) and in the use of battery storage system to reduce electricity exported to the grid” (Roselli, 2019, 488-500). The context of this version of ground is concerned with a call for increased sustainable energy. In order to acquire this type of energy absorbed heat would have to be gathered from the ground of the Earth. In relation to the other quotes, the term is described as a power source.
Based on my particular major, electrical engineering technology (EET), the definition of ground (5), according to Wikipedia, is defined as “the reference point in an electrical circuit from which voltages are measured, a common return path for electric current, or a direct physical connection to the earth” (ground, 2019). Ground (5) can be contextually expressed through the latter example of the previous paragraph. The specific context for my working definition can be expressed as, the most stable point of connection within any circuit assuring that a sense of equilibrium is in place as to avoid damage, both internally and externally (to the user).

SUBJECT: 500-Word Summary of L. Gourdo’s et al “Solar energy storing rock-bed to heat an agricultural greenhouse”
Researchers, such as Gourdo et al, have taken more consideration in the expansion of the boundaries surrounding agricultural production. Based on the article, “Solar energy storing rock-bed to heat an agricultural greenhouse” in Energy, it has been gathered that with the use of renewable energized heating technologies optimal growth for crops can be attained. As the technologies are being implemented within a greenhouse, they will be monitored through the seasons, as well as, the times in a day.
During the coldest periods of the year, maintaining agriculture is important in sustaining good land for a people. The land of Morocco, more specifically, in the region of Souss Massa areas have seen an increase in crops. Unfortunately, this increase was a part of a negative correlation as there had been a significant decrease in quality of production during the season of winter. The research of the Faculty of Science will test the effectiveness of a solar greenhouse heating system in order to make justify it as a viable solution for agricultural purposes.
As the heating systems serve as the best solution, farmers are forced to equip them only to meet the harvested products standards needed for export. The experimental heating systems of the renewable energy kind offer the most beneficial results compared to that of the conventional fossil fueled system. On the aspect of solar energy, several systems were studied but matters of pricing and installation considered obstacles. Researchers would, then, study an underground rock-bed that would be able to heat a 15 m² tunnel greenhouse. As the rocks stored solar energy from the greenhouse during the day, it would also restore it at night. To maintain the inside air temperature of a greenhouse was the goal, especially during extreme nights of winter.
The measurements of climate parameters, like temperature, relative humidity, and soil temperature, between the experimental and conventional greenhouses were taken and studied throughout the year. In order to measure parameters on the outside of the greenhouses a weather station was installed. Measurement on crop parameters weren’t disregarded as both greenhouses were fed by the same ferti-irrigation system. Specifications of rocks and layers of rock were recorded in order to facilitate the circulation of air in the reservoir of the rock-bed. Numerous tests were done on various aspects of this research in order to come to a final conclusion.
As the processes were put in motion, they eventually came to a halt. According to Gourdo et al, “In conclusion, greenhouse solar heating system, using rock-bed, is a profitable system, easy to install…” (Gourdo et al, 2019, 211). Requirements were met, from air temperature to an increase in yield. Ultimately, the efficiency of a solar heating system proved to be optimal.
