- Description: A high-performance liquid chromatographic analysis of phenylpropanolamine in human serum and urine without prior derivatization is presented. Using direct UV detection the method is sufficiently sensitive to detect 25 ng of drug/ml of serum or urine; the coefficients of variation at 25 ng/ml and 500 ng/ml were 5.16 and 2.12, respectively, in serum. The method involves serum and urine extraction at a basic pH with chloroform, a single back-extraction, and chromatography on a reverse-phase column. Serum and urine data following administration of a single 150-mg sustained-release tablet of phenylpropanolamine hydrochloride in 6 healthy volunteers demonstrates the suitability of the analytical method.

Economic geology of sulphide nickel deposits

- Description: From Chapter 1: It has been a long standing belief that many nickel sulphide ores are derivatives of magmatic processes in ultramafic and mafic rocks, and that they segregate from these magmas as immiscible sulphide droplets which are then concentrated into an orebody by gravitational settling either during intrusion or extrusion, or during the early stages of crystallization of the magma (Naldrett, 1981). Some geologists however, have suggested alternative mechanisms to explain the concentration of nickeliferous sulphides in the mafic and ultramafic hosts. These include hydrothermal replacement (Fleet, 1977), exhalative volcanic processes (Lusk, 1976), or major metamorphic upgrading of low grade, initially magmatic deposits (Barrett et al., 1977). It is not the purpose of this study to verify or disprove these hypotheses, but in so far as the initial concentration of sulphides in most deposits is concerned, these effects are relatively unimportant (Naldrett, 1981). The nickel sulphide ores associated with these mafic and ultramafic host rocks, invariably consist of nickeliferous pyrrhotite as the dominant phase, together with lesser, but variable, amounts of magnetite, pentlandite, chalcopyrite, cubanite, and platinum group elements (Reynolds, 1982).

Economic sanctions and South Africa

- Description: From Introduction: There are few more emotive and contentious contemporary issues of enduring nature than the subject of economic sanctions and South Africa. The controversy surrounding this issue has implications for the structure of international social, political and economic order. The threads of the debate are woven into the historical fabric of the past two decades, during which the acrimony of arguments both for and against sanctions on South Africa has increased. Indeed, for each argument in the debate can be found a counter-argument and "lies, damned lies and statistics" abound. The complex and widespread nature of the question has elevated a practical issue into the realm of theoretical analysis. This thesis is neither purely descriptive nor purely theoretical. It has essentially two focal points, firstly, an attempt at a systematic and reasoned investigation of the many claims and counter-claims, designed to put these arguments into a broad economic framework. There is generally a greater volume of pro-sanctions literature than anti-sanctions literature, some of which is freely available in South Africa, while some is restricted and some not available at all. However, this partial lack of accessibility would seem to pose no material problem of omission: as much of the literature is repetitive, the unavailable material is usually adequately "represented" by material which is available. Also a great part of the literature contains little or no economic analysis since it focuses more on political issues. In this respect the thesis tries to represent the main points of the broad arguments concerned rather than individual nuances and personal viewpoints. It is concerned with sanctions of an economic nature rather than wider sanctions that may affect South African citizens more generally, for example, sport and diplomatic boycotts, bans and restrictions on international travel, etc.

Effect of anticonvulsant agents on pineal gland indole metabolism

- Description: Preface: The general indications that the pineal gland might be involved in homeostasis, and more specifically the evidence suggesting a role in amelioration of seizure states warranted further investigation . No reports had examined a possible link between anticonvulsant drug administration and pineal gland function, and few enabled any type of presumption to be made as to possible effects. This study was an attempt to evaluate in which ways anticonvulsant drugs might alter pineal gland indole metabolism, with a view to increasing understanding of the role of the pineal in modulation of epileptic discharges. In order to make the study as meaningful as possible extensive preliminary investigations were necessary. Pharmacokinetic determinations gave an indication of tissue concentrations of the drugs, which could then be related to observed effects. As far as possible, where existing information was lacking, the catalytic behaviour of the various enzymes was characterised in order to explain any observed effects at a molecular level. An attempt was also made to characterise the regulatory mechanisms controlling indole metabolism, again in order to define the pharmacological effects exerted by the drugs used. The complexity of the system made it impossible to suggest a single uniform regulatory hypothesis, although some significant observations were made. Finally, the studies involving the anticonvulsant drugs were conducted on intact animals, isolated organs and individual enzymes in an attempt to determine whether the observed effects were occuring at a molecular, local or central level.

Geochemical exploration in arid and semi-arid environments

- Description: Anomalous element distributions within the regolith result from chemical adjustments of the earth's surface to prevailing climatic conditions. Because of the lack of moisture in the arid environment, chemical equilibrium related to paleoclimates is largely maintained. Mechanical or clastic dispersion dominates arid weathering and hence the exploration approach is largely dictated by the degree of preservation of the paleoregolith. Arid environment geochemists thus have to contend with surface materials ranging from laterite and calcrete in areas where the imprint of aridity is minimal, to more conventional sample media such as bedrock, stream sediment and lithic soils in actively dissecting areas. Extraction techniques are designed specifically to isolate clastic dispersion trains. Thick mantles of aeolian and water-borne overburden characterise desert lowlands and are a challenge to the exploration geochemist. Techniques showing the most promise in these areas include groundwater geochemistry, vapour geochemistry, surface microlayer geochemistry, geobotany and biogeochemistry which attempt to isolate gaseous and weak hydromorphic, ore-related trace-element dispersions. Termite mound sampling yields convincing results and appears to be an under-utilised geochemical approach. , KMBT_363 , Adobe Acrobat 9.53 Paper Capture Plug-in

Geology of the central and southern domains of the Koras Group, northern Cape Province

- Description: The Central and Southern Domains of the Koras Group, situated on the Doornberg Lineament, are the structurally preserved remnants of a once more widespread late-syntectonic cover sequence. Detailed examination of the field relationships, lithology and petrography together with new geochemical data (30 analyses) has resulted in the proposal of a new geological succession consisting mainly of two cycles of bimodal basaltic-rhyolitic volcanics with interbedded, immature conglomerates and lithic greywackes. These two cycles, named the Boomrivier and Leeudraai Formations, are overlain by the immature, polymictic orthoconglomerates and red arkosic sandstones of the Kalkpunt Formation. The first volcanic cycle commenced with the Lambrechtsdrif basaltic andesites and was followed, after a short hiatus, by the Swartkopsleegte rhyodacites. The second cycle comprises the Rouxville basalts and basaltic andesites and the Swartkop and Kenilworth rhyolites. Field evidence suggests that eruption of the rhyolitic and basaltic volcanics in the second cycle was contemporaneous. Geochemically, the volcanics can be classified as an "average-K" to high-K, tholeiitic, subalkaline association which exhibits general similarities to other Southern African bimodal associations e.g., the tholeiitic lavas of the Wilgenhoutsdrif Group. The Koras Group is petrologically similar to the Sinclair Sequence which is presently considered to be its coeval equivalent, but the dominantly calc-alkaline character of the Sinclair rocks distinguishes them from the dominantly tholeiitic Koras lavas. In a short literature review, the four main hypotheses for the petrogenesis of bimodal associations: liquid immiscibility, crystal fractionation, two-stage partial melting and separate magma sources, are described and the most feasible explanation for the origin of the Koras lavas is thought to be a "separate magma source" hypothesis in which two cycles of mantle-derived basalts and crustal-derived rhyolites were produced in a zone of high heat flow and erupted in an area of crustal weakness. The middle- or late-Proterozoic Koras Group was formed during unstable tectonic conditions, in a depositional setting that was probably controlled by late folding of the underlying pre-Koras sequences as well as the major strike-slip movement and subordinate dip-slip faulting in the Doornberg Lineament.

- Description: "Our time" is the last years of the colonial era in Africa. We are at once the most advanced country on the continent, and a relic of the past. It’s inevitable that 19th century colonialism should finally come to its end here, because here it surely reached its ultimate expression, open in the legalised land- and mineral-grabbing, open in the constitutionalized, institutionalized racism that was concealed by the British under the sly notion of uplift, the French and Portuguese under the sly notion of selective assimilation. Our extraordinarily obdurate crossbreed of Dutch, German, British, French as the South African white population produced a bluntness that unveiled everyone’s refined white racism: • the flags of European civilization dropped, and there it was, unashamedly, the ugliest creation of man, and they baptized the thing in the Dutch Reformed Church, called it apartheid, coining, to outlast Nazi terminology, the ultimate term for every manifestation, over the ages, in many countries, of race prejudice. Every country on earth could see its semblances here: and most peoples. The sun that never set over one or other of the 19th century colonial empires of the world is going down finally in South Africa.

- Description: In South Africa at present there are 104 Industrial Councils. However, the one for the Iron, Steel, Engineering and Metallurgical Industries is the largest and most important covering nearly 500 000 workers. But only about 100 000 of these workers belong to trade unions. At the Industrial Council the employers and trade unions negotiate an agreement that covers all 500 000 workers. At present on the union side there are 14 trade unions - M A W U will make it 15. But most of these unions are racial unions and what are called craft unions - that is their members only do certain kinds of jobs e.g. boilermakers or electricians etc. On the employer side nearly all the 8400 factories in the industry are members of the employer association SEIFSA. It is SEIFSA - which is the largest and most powerful employer association in South Africa - that negotiates for employers on the Industrial Council.

- Description: From Introduction: The Canadian Cordilleran Orogenic Belt forms part of the circum-Pacific orogenic zone. It underlies an area of about 1,54 million sq. kilometres, is over 2400 kilometres long and 800 kilometres wide. The region is characteristically mountainous, much of it glaciated and alpine, containing plateaux, trenches, valleys, and fjords. The mountains, in general, rise to elevations between 2100 m and 3600 m above sea level, although Mount Logan in the St. Elias Mountains attains an altitude of 6000 m. The Canadian Cordillera is divided into two dominant orogenic belts: the eastern Columbian Orogenic Belt comprising defonned miogeosynclinal rocks and the western Pacific Orogenic Belt comprising allochthonous eugeosynclinal rocks. The Cordillera is further subdivided into five longitudinal tectonic belts within which rocks are broadly similar in type, age, and history. These belts are, from east to west: the Rocky Mountain Belt, the Omineca Crystalline Belt, the Intermontane Belt, the Coast Plutonic Complex, and the Insular Belt (Wheeler et al., 1972a). The Canadian Cordillera is important in that it contains: one of the world's largest lead-zinc-silver mine, Sullivan; the second-largest molybdenum mine, Endako; one of the most important concentrations of porphyry copper deposits, Highland Valley; Canada's largest tungsten mines, Cantung and Mactung; and Canada's second-largest silver district, Keno Hill (Sutherland Brown et a1., 1971). In addition, it contains several large massive sulphide and lead-zinc deposits.

- Description: Plate tectonic theory provides logical explanations for the major tectonic events in the eastern US during Paleozoic time. The details of these tectonic events are becoming more apparent with the accumulation of new data, especially radiometric age dates. When plate tectonic theory is applied to specific tectonic events for which there is no substantial evidence, such as intracontinental hotspot rifting environments and Precambrian subduction zones, the proposed models may become very speculative. A misconception concerning the geology of the central US is that this region is structurally stable. However, geologists are currently paying considerable attention to the interlocking network of faults that in a general way follow the 38th parallel of latitude from west-central Virginia into Central Missouri (and may extend farther to the east and west). Most of the displacement along this zone occurred during the Precambrian, but different parts have moved during several periods of post-Precambrian time. In the basement the lineament may be a wide fracture zone that extends deep into the crust and is thus responsible for the magmatic iron deposits of the Southeast Missouri and may be either directly or indirectly responsible for the localization of the Mississippi Valley type deposits that occur sporadically along its length. Whether or not plate-tectonic processes operated during the Precambrian is open to speculation and the lineament may or may not be related to plate tectonic activity, but it is obvious that throughout time inherent zones of weakness are important in the localization of ore deposits. The occurrence of several major mineral districts at the intersections of the 38th parallel lineament with other major structural features, particularly in some uplifted areas and fault zone intersections, suggests that other similar structural uplifts and fault-zone intersections should be investigated for undiscovered new districts or extensions of known districts. Small uneconomic mineral occurrences along fault zones intersecting the lineament may merit further examination as they may be indications of undiscovered deposits at depth. The overall tectonic environment in the Appalachian region was an important control on the localization of massive sulfide, gold, titanium, and tungsten deposits. The deposits occur in clusters, either in Late Precambrian spreading centers and associated rift systems related to the breakup of proto-Pangea, or in Eocambrian and Devonian low-potassium tholeiitic volcanic and plutonic rocks associated with the volcanic island arc systems which developed during the closing of the Iapetus Ocean. Feiss and Hauck (1980) are confident that moderate sized (1-10 million ton) massive sulfide deposits are yet to be found at depth in these regions of the southern Appalachians, but large (greater than 20 million ton) massive sulfide deposits are unlikely to exist. The Mississippi Valley carbonate-hosted deposits of lead-zinc-baritefluorite, that occur to some extent throughout the Paleozoic section, and the Silurian "Clinton" iron ores owe their origin and distribution to normal sedimentary and diagenetic processes resulting from the transgressions of the epeiric seas. Others, such as the residual deposits of managnese iron, and aluminum, owe their existence to the afore mentioned processes, but must also have had subsequent exposure to the concentrating mechanism of weathering in a stable environment. The Mississippi Valley type occur primarily around paleo-basement highs and paleoshorelines; therefore, the formation of domes and arches within the continental interior during bathygenic episodes was a major factor controlling the localization of these deposits. These broad upwarps were preferential sites for reefal development and facies changes, and, during epeirogenic periods, these positive features have resulted in erosion and karsting of the the carbonate rocks by meteoric waters and have thus been prepared for mineralization. Deposits of this type are most common below a pre-Middle Ordovician unconformity and should be sought along major domes and arches, and along major lineaments. The association of Applachian type deposits with arches is indeterminate because a structure as subtle as an arch would be difficult to detect following overprinting by the deformation of the Alleghany orogeny; however, there is no reason to suspect that this type of positive feature did not play a role in their location. In conclusion, plate movements were a major control on the Paleozoic tectonic history of the eastern US and were also the primary control on the localization of the base metal, gold, tungsten, chromite, and titanium deposits of the southern Appalachians. However, important sedimentary and diagenetic deposits were localized primarily by arch, dome, and basin development during bathygenic episodes. Whether these submergent episodes are the result of plate motion or whether plate motion is indirectly related to submergent episodes, as suggested by Sloss and Speed (1974), remains a problem that needs to be investigated and debated further. , KMBT_363 , Adobe Acrobat 9.53 Paper Capture Plug-in

The area surveyed extends from 12hOO to 22hOO right ascension between declinations -63º and -24º. The observation technique and data reduction processes are analyzed. Digital data processing techniques used to enhance and display the data are dicussed. The results show that the Galactic emission extends as far as 40º latitude. Filamentary and loop-like structures are found superimposed on this general emission. Many of these features are unidentified as yet. A large region of emission is found to coincide with the Sco-Cen stellar association. A lower limit for the ionizing flux from the stars in the association is derived. All of the non-confused extragalactic sources with flux densities greater than O.5Jy are listed. The flux densities of these sources have been measured and any possible extended features are noted. , KMBT_363 , Adobe Acrobat 9.53 Paper Capture Plug-in
