Convection

The Sun, the closest star to Earth, and a life-sustaining necessity. It is also the center of space and solar weather, which powers and affects much of the solar system’s activities and life on Earth. Space weather goes hand in hand with the Sun’s constant gaseous activities, which depend on the Sun’s natural occurrences. This paper discusses the important topics of solar plasma, solar wind, as well as solar flares and coronal mass ejections. It also looks at human abilities to capture and use…

The Sun and Our Star - Have you ever questioned as to how and why we are able to dry our clothes in the summer, and to be able to heat food and treat our water? - This all thanks to the sun - Without the sun, we all would be dead, it gives us light, heat and energy to heat up the Earth - Most of the energy stays inside of the sun because of its gravitational pull, and all small amounts leave the surface in the form of radiant energy Type of star: Age: Yellow dwarf 4.5 Billion Years…

1. Introduction Fossil fuels are used to satisfy a very significant fraction of the world energy demands. The use of fossil fuels comes with some adverse effects, prominent among which is the emission of CO2. Carbon dioxide significantly contributes to global warming and, consequently, causes climate change. This has called for international policies like the Kyoto protocol and Copenhagen summit that set limit on greenhouse gases (GHG) emission [1]. Renewable energy sources are carbon neutral…

molybdenite. Most porphyry copper deposits can be found along the Pacific Rim and formed during the Tertiary and Quaternary periods. Porphyry copper deposits form through a series of subducting tectonic events, having a copper bearing source, and convection of hydrothermal fluids acting on an igneous intrusion. Introduction Porphyry ore deposits are some of the major resources for minerals such as copper. Porphyry copper deposits can be classified as economic copper ore bodies that form from…

Chapter 3 Experimental Setup 3.1 Test rig components and description: Fig. 3 illustrates schematic view of the test rig of an IDX-SAHP system. It was designed for a typical UK home administering up to 350 L/day of DHW. The main components are numbered in (Fig.3). The evacuated tube collector installed outdoor on a south facing roof has a surface area of 3.021 m2 with a 52-degree inclination (tilt angle). A 300L, stainless steel, insulated water storage tank has two coils immersed inside, one for…

Human Rights Act 1998 is an Act of Parliament of the United Kingdom which received Royal Assent on 9 November 1998, and mostly came into force on 2 October 2000”. Its aim is to give additional result in UK law to the rights contained in the European Convection on Human Rights. Relating this to children and young people, they were considered as “not yets” and ever since the UNCRC was introduced, they are now seen as grown-up individuals who are able to use their own human rights independently.…
