to drink or wash with. • More than two million children are dying every year from water related problems with increasing cases of cholera, dysentery and typhoid. • Seven billion people in 60 countries will face water shortage by the year 2050. In order to combat water shortages and reduce associated diseases Living Waters Technology embarked on a provision of clean water using Berkey Water System and Seychelle Water Filtration, which…

Moncada, Albina Contreras and Karla Santos Title: Interpreting the Periodic Table Date: 12-18-14 Subject: Honors Chemistry / Period 5 Introduction: The periodic table is a table of the chemical elements in which the elements are arranged by order of a atomic number. The periodic table also has a special name for its vertical columns. Each column is called a group. The elements in each group have the same number of electrons in the outer orbital. Those outer electrons are also called…

What do you think is the comparison between the Athenian agora and the Roman? Have you ever asked your self about what each has in common and how they are being used in a different way? Well, athenian Agora is an alternative name for a place in Greece. Also the Roman Forum. Both Athenian Agora and Roman Forum are located in the middle of their city Agora and Forum are linked to Greece and Roman cities, they both refer to a place where people are gathered together. Agora is used for commercial…

both ends of the tube were sealed by plugging both ends with some Vaseline. The capillary tubes were then arranged in sequence along the tube holder with a space between the 3 groups. The alcohol bath was then prepared by placing dry ice into it in order to lower the temperature to around -15°C. Gloves or paper towels were used to handle the dry ice. Temperature was checked with a thermometer once all the ice had melted. The prepared bath was then…

transition between the alpha and beta form is temperature dependent. As temperature increases, the atoms within the crystal vibrate more vigorously leading to an expansion of the thermal ellipsoids, and as a result, the atomic volume increases. In order to accommodate this increase in atomic volume, the internal crystal structure also changes through tetrahedral tilting. A highly ordered structure with higher level of symmetry is then formed. In the case of iron phosphate, as temperature…

amount of thermal diffusion which will occur when the engine endeavors. Cylinder firing order The firing order is the sequence of potency distribution of each cylinder in a multi-cylinder reciprocating engine. This is achieved by sparking of the spark plugs in a gasoline engine in the correct order, or by the sequence of fuel injection in a Diesel engine. When designing an engine, culling a felicitous firing order is critical to minimizing vibration, to ameliorate engine balance and achieving…

As with most other aspects of Rome during the republican era entering the imperial era, the arts and architecture was heavily influenced by the Roman conquest of classical Greece cite. In as much as roman architecture was derivative of that of Greece, it evolved over time becoming a style of its own (Kamm 2017b). Most times the beauty of the art and architecture was greatly affected by the wealth of the builder in question and the population density of the cities involved (Moore 1995). The…

being the temperature of solution B, and mT being the total mass of both solutions1. To calculate heat, the total mass of the solution is needed. Heat is an important factor in this experiment, because it is the determining factor for enthalpy. In order to determine the heat of the reaction, heat of the solution must be determined first by using the equation: q = (mT)*(s)*(ΔT)…

Ciminelli and Osseo-Asare, 1995; Lowson, 1982). Anderson (1951) reported 26 kJ/mol in the study of oxidation kinetics of galena (PbS) while Stenhouse and Armstrong (1952) reported an activation energy of 20 kJ/mol for the alkaline oxidation of pyrite. Koslides and Ciminelli (1992) suggested that during alkaline oxidation of sulphides, there is a change from chemical (activation energy > 40 kJ/mol) to diffusion (activation energy < 40 kJ/mol) control as the rate determining step when…

In a series of ten works, estimated to be more archaic than the Christian scriptures of the Old Testament. Vitruvius, a Roman architect and engineer, wrote the treatise: De architectura – based on a set of principles concerned with the theory of architecture, also known as the Vitruvian triad. He highlights the importance of structural integrity, utility and function, and the honesty of true beauty defined by a paradigm of, “firmness, commodity and delight.” Vitruvius’ writings established a…
