Minerals are natural inorganic substances that are found in rocks and soil and are considered essential components for human survival. Minerals compose an estimate 4% of the body and are necessary for normal functioning of the body. Humans are incapable of producing minerals which is why it is necessary to obtain minerals from plant and meat sources. Soil contains nearly 45% of minerals, wherein plants absorb all natural minerals which is absorbed in the human body upon consumption (Ward 2014). 18 minerals are considered essential out of the total 103 known minerals. Some of the major function so minerals ...

Abstract

The study of tiny particles and their applications have emerged as an important area of research in recent years. In particular, magnetic nanoparticles have attracted considerable attention due to their unique properties that make the particles useful in numerous applications. Accordingly, the present review investigates the synthesis, characterization, and biomedical applications of magnetic nanoparticles. The introduction section examines recent advances in nanotechnology and explains the significance of magnetic nanoparticles in scientific research. The section on results and discussion presents the findings of various researchers with a focus on the magnetic properties, synthesis, characterization, and biomedical applications of magnetic nanoparticles. ...

History of Solar Panel windows

Human beings had always made good use of solar energy since when the earliest ancestor of man noticed that a line of sunlight was warmer than the shade and that rocks heated throughout the day by the sun continued to stay warm through the night. Ancient structures of the Romans were constructed with south-facing windows to garner in the warmth of the sun. This was passive solar heating, which is still popular today. The only new thing about passive solar heating or solar daylighting is the name (K, Sruthi et al, 25-34). All the early attempts to harvest solar ...

1. Introduction The electrical energy is generated to bring some development to the world. The electrical energy lights the world during night time. People can do their work even during night time without any disturbance because the electrical energy replaces the sun during night time. The energy is neither be created nor be destroyed. The electrical energy is generated by converting other form of energy. Generally mechanical energy is converted in to electrical energy. The electrical energy is generated by different methods; say hydro thermal energy generation, diesel power generation, gas power generation, and nuclear power generation. The ...

Introduction

The above quote alludes to the pliability and the malleability of plastic. Plastic is defined by the online version of the Merriam-Webster Dictionary as a synthetic material which is comprised of a variety of organic polymers which can be moulded into a shape while soft, and then set into a rigid, yet slightly flexible form. Glass fibre reinforced plastic (GFRP) is plastic which has been reinforced or strengthened by the use of glass fibres. This composite material has been used in the construction of large-scale items such as luxury boats, missiles, and tanks, and small-scale items, such as tubs, fans, hoods and scrubbers [ ...

The question of where life originated is almost as old as life itself. While humanity has likely always been self-aware, at least as long as it has existed, the source of the first life on Earth is still a mystery. In ancient times, cultures came up with cosmogonic myths that sought to explain the source of life. One example is the Judeo-Christian cosmogonic myth, in which God is an immortal being who was the only Life, hovering above some waters, before creating what would become the planet Earth and then filling it with life. There are other myths that envision a ...

Introduction

Utilitarianism is a doctrine which provides for actions to be right so far as they useful and they benefit majority. The doctrine also provides that an action is right if it promotes happiness, or maximizes happiness. Therefore utilitarianism provides the moral worth of an action in assessing the utility in providing happiness. Utilitarian also measure the extent of usefulness of the law in the extent it provides happiness, decrease injustice and poverty. It majorly deals with happiness of the immediate actor or those affected by the actions. The theory of consequentialism on the other hand provides for how a moral act ...

Pressurized Water Reactors

Primary Systems of A PWR These water reactors also use steam to turn a turbine and hence generate steam. However, the mode of cooling the steam is different from that of boiling water reactors. Steam is directed to the condenser where cool water is used in the removal of excess heat. This system comprises of two systems: the primary and secondary systems. Primary system comprises of the steam generators, reactor vessel, coolant pumps, pressurizer and connecting piping. The primary system (reactor coolant system) functions to transfer heat to the steam generators from the fuel. It also serves to house ...

In the U.S. two types of standard structural bolts have been approved for use: ASTM A490 and ASTM A395 (Williams, 2001, p. 44).

ASTM A395

Usually, the ASTM A325 covers the heavy structural bolts with high strength that range in size from half diameter to one and half diameter. The given bolts are often used in various structural connections (Williams, 2001, p. 54). They characteristically have shorter thread lengths when compared to the standard hex bolts. There are two types of A325: Type 1 and type 3. Type 1 is made of carbon baron, medium carbon, or an alloy of medium ...

Diamond has several applications: it is used for decoration, to manufacture high quality stereo equipment in addition to being included in cutting instruments. It is therefore important to determine the quality of the diamond. This can be done a simple, nondestructive method that is known as Raman spectroscopy. This method is used in the characterization of the morphology of the molecules of carbon materials. The bands that are detected on the Raman spectrum are dependent on the frequency of the vibrations which is attributed to the bonds within the molecule. This technique has several applications in diamond science: it is ...
