L.C. Foxcroft,L. Henderson,G.R. Nichols,B.W. Martin
Koedoe : African Protected Area Conservation and Science , 2003, DOI: 10.4102/koedoe.v46i2.54
Abstract: Alien plants recorded in the Kruger National Park are listed, providing an update of species that have been recorded since the last published list in 1988. The serious consequences that invasive alien plants pose are widely recognised internationally and are regarded as the greatest threat to the Kruger National Park. It is extremely important to maintain an updated list of species to use as a reference and from which to monitor changes in the influx of invasive species. The list contains the invasive status of the plants, current impact, habitat types, biological control status and status according to the Conservation of Agricultural Resources Act (CARA), Act 43 of 1983, as amended in March 2001. The list comprises 370 species, of which 121 are invaders and two are transformer weeds, which may cause considerable damage and alterations to the indigenous biodiversity. A total of 91 species listed herein are also listed in the CARA regulations or are proposed additions to the CARA regulations.

Comparative Study of Breast-Feeding State among Fars (Native) Torkman, and Sistani Ethnic Group of Rural Areas in Gorgan District
G.R. Veghari
Pakistan Journal of Nutrition , 2006,
Abstract: This study is a epidemiological description study that has been carried out for determining the status of breast feeding and extra feeding in the children of the Gorgan rural. Three race of the Gorgan rural such as Fars (native), Torkman and immigrants of sistani have been compared. Among 118 Gorgan rural, 20 of them were chosen by systematical simple random way. All children of 0-6 years old were studied. On the whole, 2890 children were studied. Results showed that 1) in the first six-month after birth, 86.1% children are nourished by breast milk. The Torkman races have significant statistical differences with Fars (native) and Sistani races (p< 0.05), 2) 34.6% children of Gorgan rural have begun extra feeding from six-month age. The highest and the lowest ratio have been observed in sistani (40.1%) and Fars (native) children (30.5%) respectively, 3) in the Gorgan children, the rate of the breast-feeding is higher than that was reported for whole the country. The children of the sistani race who live in Gorgan rural should be more supported from the nutritional viewpoint and the education of the breast-feeding must be considered more than the others. According to the results of this study, it can be conclude that social and cultural factors could change in the patterns of the children` nutrition.

Abstract: Objective: The aim of the study was to evaluate the frequency of infection in clean surgical cases (General & Orthopaedic). Study Design: A descriptive study. Place & Duration of Study: This descriptive study was conducted at department of surgery & orthopaedic DHQ Teaching Hospital Sargodha from July 2007 to Dec, 2008. Patients & Methods: In this study 1500 clean surgical cases were included. Wounds were examined on third post operative day and then regularly after removal of stitches. Surgical wounds were examined finally on fifteenth post operative days. Description of wound condition and detailed data of patients were collected on preformed performas. Patients with wound infection developed pain at operation site and fever on third post operative day. Wounds were examined for swelling, redness, discharge; stitch abscess. Routine investigations were done as per protocol ie complete blood examination, complete urine examination, blood sugar, C-reactive proteins etc. Wounds swab was taken for microscopy and culture sensitivity. Results: This study was carried out on fifteen hundred clean surgical cases (General & Orthopaedic). There were 1064 males and 436 females. Male to Female ratio was 2.4: 1. Infection was detected in 110 patients (7.3%) while no infection was found in 1390. Infection was maximum in patients more than 60 yrs of age (10.9%). Wound infection was minimum in young patients (3.5%).commonest micro organism isolated from the infected wound was staphylococcus areus. Other organism isolated was streptococcus pyogenes, proteus and pseudomonas. No MRSA was detected. Conclusion: In our case study clean cases were found generally free of infection especially young patients. Whereas increased incidence of infection was noted in old patients. Wound infection is associated with significant morbidity in the form of delayed wound heeling, prolonged hospital stay and increased economical pressure on the patient.
Annali di Botanica , 1997,
Abstract: Even in so called undisturbed forest ecosystems there have always been all sorts of changes in structure and species composition going on. The presented study tries to distinguish between natural changes in species composition due to the natural forest life-cycle and new occurring, possibly man induced changes in forest vegetation, which have happend within the last thirty years. General trends have been elaborated and different causes drawn up. More detailed results concerning beech forest are presented and discussed in a broader context with other recent studies conducted in Europe to the same topic.

Neurocirugía , 2010,
Abstract: La neuralgia del trigémino continúa siendo una enfermedad desconocida para muchos médicos generales y lo que resulta aun peor, mal manejada por muchos de los especialistas encargados de la misma. En este trabajo se resumen las principales características anatomo-clínicas, fisiopatológicas y terapéuticas de esta entidad. Trigeminal neuralgia continues to be an illness poorly known for many general practitioners and what is even worse, badly handled by many of the specialists in charge of cephalic neuralgias. In this paper I resume the main knowledge about trigeminal neuralgia reviewing the clinical, physiopathological, and therapeutical aspects of this condition.
Currently important animal disease management issues in sub-Saharan Africa : policy and trade issues
G.R. Thomson
Onderstepoort Journal of Veterinary Research , 2010, DOI: 10.4102/ojvr.v76i1.76
Abstract: The present international approach to management of transboundary animal diseases (TADs) is based on the assumption that most can be eradicated ; consequently, that is the usual objective adopted by international organizations concerned with animal health. However, for sub-Saharan Africa and southern Africa more particularly, eradication of most TADs is impossible for the foreseeable future for a variety of technical, financial and logistical reasons. Compounding this, the present basis for access to international markets for products derived from animals requires that the area of origin (country or zone) is free from trade-influencing TADs. The ongoing development of transfrontier conservation areas (TFCAs), extending across huge areas of southern Africa, therefore presents a development conundrum because it makes creation of geographic areas free from TADs more difficult and brings development based on wildlife conservation on the one hand and that based on livestock production on the other into sharp conflict. Sub-Saharan Africa is consequently confronted by a complex problem that contributes significantly to retarded rural development which, in turn, impedes poverty alleviation. In southern Africa specifically, foot-and-mouth disease (FMD) presents the greatest problem in relation to access to international markets for animal products. However, it is argued that this problem could be overcome by a combination between (1) implementation of a commodity-based approach to trade in products derived from animals and (2) amendment of the international standards for FMD specifically (i.e. the FMD chapter in the Terrestrial Animal Health Code of the World Organisation for Animal Health [OIE]) so that occurrence of SAT serotype viruses in free-living African buffalo need not necessarily mean exclusion of areas where buffalo occur from international markets for animal products. This would overcome a presently intractable constraint to market access for southern African countries and enable conservation and livestock production to be more effectively integrated, to the benefit of both.

Abstract: One reason why there is 'always something new out of Africa' is that there are so few old, all-embracing and extensive institutions capable either of denying or of even moderating change. Africa is a most exciting continent, in part because of its potential for change. This is in sharp contrast to the cultural and religious limitations on change characteristic of much of Latin America, Southeast Asia, and the Middle East. New ideologies, new politics, new constitutions and procedures, are to be expected out of Africa. (p. 18
Origins of the thick disk of the galaxy as traced by metal-poor stars selected from RAVE
Ruchti G.R.
EPJ Web of Conferences , 2012, DOI: 10.1051/epjconf/20121904003
Abstract: Models of the formation of the thick disk of the Milky Way Galaxy make specific predictions about the chemical abundance properties of the metal-weak (and oldest) stellar population in the thick disk. We have undertaken the study of the elemental abundances and kinematic properties of a sample of 319 candidate metal-poor thick-disk stars selected from the RAVE spectroscopic survey of bright stars. Our aim is to differentiate among the present scenarios of the formation of the thick disk. In this study, we measured the abundances of several alpha-elements and found that the thick-disk [alpha/Fe] ratios are enhanced, implying that enrichment proceeded by purely core-collapse supernovae. Further, the sample probes distances ranging out to about 2 kpc from the Sun, allowing for the investigation of the gradients in the thick disk. I will discuss the results from these investigations and how they compare to the predictions made by present models of the formation of the thick disk.
