Introduction The notion of place in the geographical sciences is an ambiguous and multifaceted construction that is constantly influenced by different social and personal interpretations. The concept is complex, and in order to uncover it, it is necessary to delve deeper into its determination based on a place. The example...
Introduction Down syndrome is a genetic condition that results from an additional copy of the twenty-first chromosome. This poses a problem for sick people and their families. Progress has been achieved in comprehending this condition’s molecular and physiological aspects. However, it is still necessary to delve deeper into its basic...
Charles Darwin was an extraordinary scientist who substantially changed the perception of the world. His impact can only be described by the term zeitgeist. In this case, it means that Darwin’s impact was the most revolutionary change of his epoch. Mayr (2000) states that his findings were so crucial that...
Introduction The Halifax Waterfront is located in Nova Scotia and represents a dynamic waterfront area that combines industrialization and nature. This study aims to survey and explore the Halifax waterfront area. This is important to collect data for analysis and study it to understand people’s impact on the natural environment...
Introduction It is challenging to disagree that nature can surprise humans with beautiful animals and birds, more like magical creatures from fantasy books and movies than from the real world. It is common for many of them to become an integral part of the culture or acquire symbolic meanings and...
Introduction Archaeology and the first human colonization of the Caribbean are important sections of history. The Caribbean was the last large territory of the Americas to become populated. Wilson (2007) notes that the first inhabitants of the Caribbean had a distinctive course of development differing from those taken by other...
Introduction Smelting iron is a critical process in the industry. It turns iron ore into usable iron metal, which is needed in many areas. I need to understand the chemical reactions because they are crucial for improving the process. The results can reduce its impact on the environment. The research...
Overview: Title, Abstract, and Purpose The article by Matricciani et al. (2018) is an original study focused on researching sleep as a multidimensional construct by examining all the characteristics of sleep and their connections with health.
