History Of

Most of rural people even today depend on plants for medicines. The use of complentary and alternative medicine (CAM) has become increasingly popular worldwide, such that an estimated 38% of American adults reported using a form of CAM in 2006. The study of herbal remedies is common because many diseases and infections are known to have been treated with natural medicinal plants throughout the history of humanity. Ruta graveolens is aromatic shrub belong to family rutaceae and is commonly known as rue, cultivated as ornamental and medicinal herb in gardens. Due to its cultural and medicinal value, rue has been introduced in various countries of North, Central and South America, China, India, Middle East and South Africa. This plant also contains glucoside rutin. The flavonoids are a part of primary chemical components of Ruta graveolens Linn. The most important analyzed flavonoids are rutin (quercetin-3-β- rutinoside) that belongs to flavonol glycoside. Quercetin is other major flavonoids found in Ruta graveolens and can also be obtained by rutin hydrolysis.

Ethnobotanical Uses

Plants of the genus Zingiber (Family Zingiberaceae) are widely used throughout the world as food and medicinal plants. They represent very popular herbal remedies in various traditional healing systems; in particular, rhizome of Zingiber spp. plants has a long history of ethnobotanical uses because of a plethora of curative properties. Antimicrobial activity of rhizome essential oil has been extensively confirmed in vitro and attributed to its chemical components, mainly consisting in monoterpene and sesquiterpene hydrocarbons such as α-zingiberene, ar-curcumene, β-bisabolene and β-sesquiphellandrene. In addition, gingerols have been identified as the major active components in the fresh rhizome, whereas shogaols, dehydrated gingerol derivatives, are the predominant pungent constituents in dried rhizome. Zingiber spp. may thus represent a promising and innovative source of natural alternatives to chemical food preservatives. This approach would meet the increasing concern of consumers aware of the potential health risks associated with the conventional antimicrobial agents in food. This narrative review aims providing a literature overview on Zingiber spp. plants, their cultivation, traditional uses, phytochemical constituents and biological activities.

Abstract Mineralogical and textural variability of ores from different sources commonly leads to processing inefficiencies, particularly when a processing plant is designed to treat ore from a single source (i.e. ore of a relatively uniform composition). The bulk of the Witwatersrand ore in the Klerksdorp goldfield, processed at the AngloGold Ashanti Great Noligwa treatment plant, is derived from the Vaal Reef (>90%), with a comparatively small contribution obtained from the Crystalkop Reef (or C-Reef). Despite the uneven contribution, it is of critical importance to ensure that the processing parameters are optimized for the treatment of both the Vaal and C-Reefs. This paper serves to document the results of a geometallurgical study of the C-Reef at the Great Noligwa gold mine in the Klerksdorp goldfield of South Africa, with the primary aim of assessing the suitability of the processing parameters that are in use at the Great Noligwa plant. The paper also draws comparisons between the C-Reef and the Vaal Reef A-facies (Vaal Reef) and attempts to explain minor differences in the recovery of gold and uranium from these two sources. Three samples of the C-Reef were collected in-situ from the underground operations at Great Noligwa mine for mineralogical analyses and metallurgical tests. Laboratory-scale leach tests for gold (cyanide) and uranium (sulphuric acid) were carried out using dissolution conditions similar to that in use at the Great Noligwa plant, followed by further diagnostic leaching in the case of gold. The gold in the ore was found to be readily leachable with recoveries ranging from 95% to 97% (as opposed to 89% to 93% for the Vaal Reef). Additional recoveries were achieved in the presence of excess cyanide (96% to 98%). The recovery of uranium varied between 72% and 76% (as opposed to 30% to 64% for the Vaal Reef), which is substantially higher than predicted, given the amount of brannerite in the ore, which is generally regarded as refractory. Thus, the higher uranium recoveries from the C-Reef imply that a proportion of the uranium was recovered by the partial dissolution of brannerite. As the Vaal Reef contain high amounts of chlorite (3% to 8%), which is an important acid consumer, it is considered likely that this could have reduced the effectiveness of the H2SO4 leach in the case of the ore of the Vaal Reef. Since the gold and uranium recoveries from the C-Reef were higher than the recoveries from the Vaal Reef, the results demonstrate that the processing parameters used for treatment of the Vaal Reef are equally suited to the treatment of the C-Reef. Moreover, small processing modifications, such as increased milling and leach retention times, may well increase the recovery of gold (particularly when e.g. coarse gold, or unexposed gold, is present).

Primary Focus

The recent entry of the US multinational Walmart into South Africa has proved to be a source of controversy. Key stakeholders in South Africa objected to the merger and attempted to block it unless certain conditions were met. The aim of this study was to examine the controversy and the conditions surrounding the merger. The research employed a qualitative archival analysis to examine publicly available sources of information with regard to the merger. The findings revealed key stakeholders’ concerns that Walmart’s entry would lead to an increase in imports which would displace local producers, increase unemployment, marginalise trade unions and lower labour standards unless certain conditions were met. The results also revealed problems relating to the firm’s primary focus on “business” while neglecting “public interest” issues, naively relying on their “local retailer” to manage key stakeholders, and assuming that their perceived controversial reputation regarding treatment of trade unions and their views about unemployment as well as the controversies surrounding their history of entry into other global markets would not have the major negative impact it did on stakeholders in South Africa.

First Time

The history of local government in South Africa dates back to a time during the formation of the Union of South Africa in 1910. With regard to the status of local government, the Union of South Africa Act placed local government under the jurisdiction of the provinces. The status of local government was not changed by the formation of the Republic of South Africa in 1961 because local government was placed under the further jurisdiction of the provinces. Local government was enshrined in the Constitution of the Republic of South Africa arguably for the first time in 1993. Under the interim Constitution local government was rendered autonomous and empowered to regulate its affairs. Local government was further enshrined in the final Constitution of 1996, which commenced on 4 February 1997. The Constitution refers to local government together with the national and provincial governments as spheres of government which are distinctive, interdependent and interrelated. This article discusses the autonomy of local government under the 1996 Constitution. This it does by analysing case law on the evolution of the status of local government. The discussion on the powers and functions of local government explains the scheme by which government powers are allocated, where the 1996 Constitution distributes powers to the different spheres of government. Finally, a conclusion is drawn on the legal status of local government within the new constitutional dispensation.

History Of

The history of the formation of South Africa as a single state is closely intertwined with events of international scale, which have accordingly influenced the definition and development of the main characteristics of the foreign policy of the emerging state. The Anglo-Boer wars and a number of other political and economic events led to the creation of the Union of South Africa under the protectorate of the British Empire in 1910. The political and economic evolution of the Union of South Africa has some specific features arising from specific historical conditions. The colonization of South Africa took place primarily due to the relocation of Dutch and English people who were mainly engaged in business activities (trade, mining, agriculture, etc.). Connected by many economic and financial threads with the elite of the countries from which the settlers left, the local elite began to develop production in the region at an accelerated pace. South Africa’s favorable climate and natural resources have made it a hub for foreign and local capital throughout the African continent. The geostrategic position is of particular importance for foreign policy in South Africa, which in many ways predetermined a great interest and was one of the fundamental factors of international involvement in the development of the region. The role of Jan Smuts, who served as Prime Minister of the Union of South Africa from 1919 to 1924 and from 1939 to 1948, was particularly prominent in the implementation of the foreign and domestic policy of the Union of South Africa in the focus period of this study. The main purpose of this article is to study the process of forming the mechanisms of the foreign policy of the Union of South Africa and the development of its diplomatic network in the period from 1910 to 1948.

African Context

The history of the Christian Bible’s reception in South Africa was part of a package that included among others, the importation of European patriarchy, land grabbing and its impoverishment of Africans and challenged masculinities of African men. The preceding factors, together with the history of the marginalization of African women in bible and theology, and how the Bible was and continues to be used in our HIV and AIDS contexts, have only made the proverbial limping animal to climb a mountain. Wa re o e bona a e hlotša, wa e nametša thaba (while limping, you still let it climb a mountain) simply means that a certain situation is being aggravated (by an external factor). In this chapter the preceding Northern Sotho proverb is used as a hermeneutical lens to present an HIV and AIDS gender sensitive re-reading of the Vashti character in the Hebrew Bible within the South African context.

Fitting In

While small in number, the place of the Indian in South Africa has historically loomed large because of their strong commercial and professional middle class, international influence through India, the commitment of many Indians to the anti-apartheid struggle and the prominent role that they have played in political and economic life post-apartheid. A History of the Present is the first book-length overview of Indian South Africans in the quarter century following the end of apartheid. Based on oral interviews and archival research it threads a narrative of the lives of Indian South Africans that ranges from the working class men and women to the heady heights of the newly minted billionaires; the changes wrought in the fields of religion and gender; opportunities offered on the sporting fields; the search for roots both locally and in India that also witnesses the rise of transnational organizations. Indians in South Africa appear to be always caught in an infernal contradiction; too traditional, too insular, never fitting in, while also too modern, too mobile. While focusing on Indian South Africans, this study makes critical interventions into several charged political discussions in post-apartheid South Africa, especially the debate over race and identity, while also engaging in discussions of wider intellectual interest, including diaspora, nation, and citizenship.
