Pengembangan Dan Pengelolaan Eboni Dalam Sistem Daerah Penyangga
The increasing value of ebony (Diospyros celebica Bakh.) recently, causes extensive exploration of the species, and as the consequency the natural population of this species become endangered.Conservation of ebony depends on the management of the Nature Conservation areas or the National Parks in Sulawesi.Conserving the gene pool and management of the surrounding area i.e.the buffer zone is important for the species diversity and the social economic aspect of the local community.The buffer zone has three different functions, as greenbelt zone, interaction zone and cultivation zone.These zones are managed in an integrated system where the progress of the region is responsible on the conservation and community development is implemented. The progress of the ebony forest plantation and agriculture zone of the buffer zone area develops into a mixed plantation forest of an agroforestry system in a community forest management
Manufacturing Of Robust Natural Fiber Preforms Utilizing Bacterial Cellulose as Binder
We present a novel method of manufacturing rigid and robust short natural fiber preforms using a papermaking process. Bacterial cellulose acts simultaneously as the binder for the loose fibers and provides rigidity to the fiber preforms. These preforms can be infused with a resin to produce truly green hierarchical composites
Microwave curing of carbon-epoxy composites: Penetration depth and material characterisation
Microwave heating has several major advantages over conventional conductive heating when used to cure carbonâepoxy composites, especially in speed of processing. Despite this and many other well-known advantages, microwave heating of carbonâepoxy composites has not taken off in industry, or even academia, due to the problems associated with microwave energy distribution, arcing, tool design and (ultimately) part quality and consistency, thus leading to a large scepticism regarding the technique/technology for heating such type of materials. This paper presents some evidence which suggests that with the correct hardware and operating procedure/methodology, consistent and high quality carbonâepoxy laminates can be produced, with the possibility of scaling up the process, as demonstrated by the micro- and macro-scale mechanical test results. Additionally, the author proposes a methodology to practically measure the maximum microwave penetration depth of a carbonâepoxy composite material

Analysis of the fecal and oral microbiota in chronic recurrent multifocal osteomyelitis
Chronic recurrent multifocal osteomyelitis (CRMO) is a rare autoinflammatory bone disease for which a lack of bacterial involvement is a key diagnostic feature to distinguish it from other symptomatically related diseases. However, the growing evidence suggesting an involvement of the host-associated microbiota in rheumatic disorders together with the now wide accessibility of modern culture-independent methods warrant a closer examination of CRMO

Using the postâoperative quality recovery scale to evaluate recovery with different neuromuscular blocking reversal agentsin the Portuguese population â interim analysis results: 1AP3â8
Background and Goal of Study: Post-operative Quality Recovery Scale
(PQRS), is the first scale evaluating several domains of postoperative recovery.
The objectives of this study were to compare overal and physiologic, cognitive,
and functional domains of post-operative recovery af ter elective surgical
procedures using neostigmine or sugammadex as neuromuscular blocking
(NMB) reversal agents, to validate the use of PQRS in the Portuguese
population and to objectively assess muscular strength recovery.
Materials and Methods: Prospective multicenter observational study
comparing postoperative recovery between 2 cohorts of 50 adult patients
submitted to elective surgical procedures with general anesthesia using
Nondepolarizing Muscle Relaxants and NMB reversal with neostigmine or
sugammadex. Measurements obtained using Portuguese version of PQRS
at dif ferent timepoint: baseline,15 minutes (T15), 40 minutes (T40), one and
three days af ter surgery. Full recovery defined as return to values identical or
higher than those measured at baseline, prior to surgery. Muscular strength
measured with KERN- MAPÂź Dynamometer. Ethics Committees approval was
obtained. Statistics used linear T-Test, Qui Square and Fisher exact test, data
presented as mean±SD for continuous variables. Interim analysis results presented
Results and Discussion: Thirty patients received neostigmine and 21 sugammadex.
Age and BMI 50.4±11.8 and 28.6±5.6 in the neostigmine group
and 38.2±12.7 and 24.7± 4.5 in the sugammadex group (p< 0,001). Overall
response rate at T15 was 86% for neostigmine and 95% for sugammadex (p=
0.22). Dif ferences in favor of sugammadex group noted in nociceptive and
emotional domains, 80 vs 100% respectively (p=0.04). Overall response rate
at T40 was 80% for neostigmine and 65% for sugammadex (p=0.33), primarily
reflecting constraints on activities of daily life. Muscular strength did not
dif fer. Improvements in recovery scores from T15 to T40 were observed in
both groups, without significant dif ferences . Postoperative assessments were
feasible using PQRS at T15 and T40 and seem appropriate for comparisons
between postoperative recovery domains and overall recovery . These preliminary
results suggest nociceptive and emotional domains recovery at T15
may be faster with sugammadex.
Conclusion: The results support the adopted PQRS validation process and
the potential of this scale as a tool for the evaluation of post operative recovery
evaluation in the Portuguese populatio
Impediments to Marketing African Natural products From Ghana: Preliminary Results
For most of the African countries agriculture still remains the mainstay of the economies supplying both food and incomes via marketable surpluses. However, many odds against agriculture such low productivity, poor prices, and drought among others make it unsustainable. Results thus far show that such dependence has contributed little to neither economic development nor growth. Still many of its people living on and from agriculture remain poor, and are susceptible to hunger and malnutrition. Additionally, their over reliance on a few traditional exports such coffee, tea, and cocoa etc., products whose world prices keep declining has not helped either. At most this is futile response to raising incomes of its people, let alone spur any meaningful development. Agricultural may still contribute to development, if the countries could diversify from traditional products to the untapped areas. The continent's rich botanical heritage offers an excellent opportunity to diversify away from traditional exports. The natural products have a greater appeal to consumers especially in the rich west. Thus, development of natural products as alternative or complimentary to the current mix of tradable products will positively impact the social and economic lives of many people, especially those in the rural areas. Additionally, diversification of the production systems to include natural plants provides a superior route to the creating viable agribusinesses in rural communities currently lacking. Natural products happen to have enormous advantages; First, indigenous African plants occur naturally and so are relatively easy to cultivate commercially. Second, natural plant production is labor intensive rather than capital intensive, and so minimizes capital investment while at the same time maximizing job-creation potential. Third, African communities have extensive knowledge of indigenous plants, creating a natural competitive advantage in this sector. ASNAPP (Agribusiness in Sustainable Natural African Plants Products) a non-profit organization formed in 1999 with funding from USAID (United States Agency for International Development) is helping create and develop successful African agribusinesses in the natural plant products sector. The organization focuses on the development of high-value natural plant products that enable African agribusinesses to compete in local, regional and international markets. These products include herbal teas, culinary herbs and spices, essential and press oils, as well as medicinal plants. Currently, ASNAPP operates in five countries, namely South Africa, Ghana, Rwanda, Senegal and Zambia, working with 25 agri-enterprises that represent more than 2000 small-scale natural plant suppliers. The prospects for natural products market is very bright, for example the global nutraceutical market alone is estimated to be worth 34 billion in 2001, It is estimated that Global sales for organic and natural products will reach about 316 million dollar business in 1996 to over 42 Billion" Natural Foods Merchandiser, 2004, volume XXV/number 6/ p. 1 Organic Natural health, 2001. http://www.health-report.co.uk/organic-cosmetics-usa- opportunity.htm#Organic/natural%20industry%20profileInternational Relations/Trade,
