Abstract
Malachite is a copper carbonate hydroxide compound naturally present in water surfaces above the copper deposits. It’s a divalent copper compound with a chemical composition of Cu2(CO3)(OH)2. Due to its distinct idiochromatic coloration it is used in sculpture, coloring agents and other industrial uses including algaecides and microbicide development, antibiotics, and textile industry. It has toxic effects Continue reading...

A Study on the effects of Squeeze Pressure on Microstructure, Mechanical Properties, and Wear Characteristics of Near-Eutectic Al-Si Piston Alloys with variable Cu contents.

Abstract:

This paper discusses the effects of squeeze pressure on the microstructure, wear characteristics and the mechanical properties of near eutectic Al-Si piston alloys with variable Copper (Cu) content. The paper starts with a description of Al-Si alloys and the features that make them desirable for use as piston alloys. The impact of alloying elements on the mechanical properties, microstructure and wear characteristics are also discussed where it is determined that adding alloying elements such as Continue reading...

Jade in Bronze in the Bronze Era

Introduction
Jade is an ornamental rock; it applies to the two categories of a type of rock called metamorphic which is made up of different silicate minerals. The two minerals are Nephrite and Jadeite.
Bronze Age refers to that period which was characterized by the use of bronze and other early features of urban civilization. The bronze was classified by Christian Jurgensen at the second time of the three age stone bronze iron system. The ancient culture was defined to be in the Bronze Age. Bronze Age culture was different in their development of the first writing. Bronze Age Continue reading...

Introduction

The article discusses the archaeology of China and the conclusions drawn from the archaeology. Special emphasis is given to the Sanxingdui and Anyang archaeological sites and their roles in the Chinese civilization. The two areas are similar interms of the artifacts found such as the tools, living structures and burial structures. The document also does a comparison of the two sites. In addition to that, the agricultural practices of the ancient people is discussed with emphasis on the adoption of agriculture and the domestication of crops such as rice ans millet. the high population of the country, China ranks Continue reading...

Zhang Changshou. 2000. A Comparative Study of the Ding Bronze Vessels from Xin'gan.
This study by Zhang Changshou entails a comparative analysis of the ding bronze vessels from the Central Plains with those from Xin’gan in Southern China. This is after the discovery of numerous vessels and objects in a large tomb in Xin’gan in Dayangzhou, Jiangxi Province during 1989. Some of the equipment that was discovered included pottery, weapons, bronze tools and jades. A large percentage of the ding vessels discovered were made of bronze giving an indication of the huge significance of Xin’gan bonze Continue reading...

Abstract

For centuries, mining has been taking place in different parts of the world, from the shallow waters, deep waters and even on dry land. Some mining activities having been a result of natural happenings such as flooding, while others have been a result human activity, which leads to environmental degradation that in return leads to discovery of metals and minerals, such as soil erosion. However, for the existence of some minerals to be discovered, it was influenced by the human nature of curiosity or through scientific experiments. The Tamar Valley Region, North of Plymouth in Southwest England is one Continue reading...

KGHM International has become a diversified mining company operates different projects around the globe, and it is a base for expansion for its parent company, KGHM Polish Copper, Inc. We have visited the one of their underground mine called McCreedy West Mine on March 9, 2015.This mine mainly produce copper, Nickel and some of gold. Each of their operational is uniquely in this mine. They value and distinguish each of their unique procedures and do the best to be perfect in all places where they operate.
During the visit to the McCreedy West Mine, we learnt that they believe Continue reading...

Abstract:

In this research, the effects of pressure on the wear resistance characteristics, mechanical properties and the microstructures of Al-Si piston alloys that have variable Magnesium (Mg) content is studied. The paper begins with an explanation of the desirable properties of eutectic Al-Si alloys and why their chemical and mechanical properties are desirable in the fabrication of light weight machine components. The methods of strengthening the alloys further using alloying elements such as Ni, Cu and Mg, and applying heat treatment are also discussed. The paper also places major emphasis on the addition of Magnesium, and compares the traditional gravity Continue reading...

The Metropolitan Museum and its exhibition and interpretation of fine art is arguably among the best in the world (Karp & Lavine 7). The Metropolitan Museum has combined most of the non-Western materials in a single wing named the arts of Africa, Oceania and the Americas. The exhibit is stunning with a wide variety of beautiful and quite large objects. Monumental wooden objects from Africa and New Guinea fill the display space. The museum balances the use of both traditional and modern exhibit forms to present the cultures of societies. Examples include reenactment, period setting, dioramas, photography, audio and video Continue reading...

Metabolic Physiology of Domestic Animals

Introduction
For domestic animals such as cattle to have sound immune systems they need to have vitamin and mineral nutrition in the diets. Some of the minerals such Selenium is naturally found in animal feeds, but they can be manufactured through the use of residue from the manufacture of copper. Good nutrition in animals help in their growth and development thus there is a need to ensure that the cattle feeds has the right quantity of vitamins and minerals. The nutrition also helps in calf weight gain and reproductive performance. One of the most recommended minerals in domestic animals Continue reading...
