Sequential ejectile decays and uncorrelated breakup processes in the 14N + 159Tb reaction

From a study of particle-particle correlations, involving position-sensitive detector telescopes, conclusive evidence for sequential ejectile decay was found, and the relative importance of sequential decay and of breakup processes, which were observed to be uncorrelated in angle, could be determined

Inventorying geological heritage in large territories : a methodological proposal applied to Brazil

An adequate management of geological heritage by national and regional authorities presupposes the existence of a solid geosites inventory. Unfortunately, this is not the case for many countries. Most often, there is no national inventory at all or the method and criteria used to assess geosites was not adequate. This paper makes an overview of the strengths and weaknesses of the most common procedures to produce a geosite inventory and proposes a methodology particularly adapted for large territories such as Brazil. Nevertheless, this methodological approach can be easily adapted to any other geographical or geological setting, promoting the characterization and conservation of the world's geological heritage.High Level Scholarship Programme of the European Union - Programme AlβanFundação para a Ciência e a Tecnologia (FCT)

Een klosprothese bij een palatumperforatie door cocaïnegebruik

Deze bijdrage behandelt de ziektegeschiedenis van een thans 54-jarige man met een uitgebreide perforatie van het palatum als gevolg van chronisch cocaïnegebruik. Om de lekkage van drank naar de neus te voorkomen en zijn spraakproblemen te verhelpen, werd een uitneembare klosprothese geconstrueerd. De ervaringen van de patiënt met deze klosprothese worden beschreven

Mycobacterium avium Subspecies paratuberculosis DNA and Antobodies in Dairy Goat Colostrum and Milk

Mycobacterium avium subspecies paratuberculosis (MAP) is endemic in the Dutch dairy goat population causing economic loss, and negatively influencing welfare. Moreover, there are concerns about a potential zoonotic risk. Therefore the industry’s objectives are to decrease MAP prevalence, limit economic losses as well as reduce the concentration of MAP in (bulk) milk. To diminish within-farm spread of infection, vaccination, age dependent group housing with separation of newborns from adults, as well as rearing on artificial or treated colostrum and milk replacers are implemented. However, the importance of MAP contaminated colostrum and milk as a route of infection in dairy goat herds is unknown. Therefore the aim of this study was to detect the presence of MAP DNA in colostrum and milk from dairy goats in infected herds. A convenience sample of 120 colostrum samples and 202 milk samples from MAP infected dairy goat herds were tested by IS900 real-time Polymerase Chain Reaction (PCR) for MAP DNA. Furthermore, 22 colostrum samples and 27 post mortem milk samples of goats with clinical signs consistent with paratuberculosis from known infected herds were tested. The majority of samples were from goats vaccinated against MAP. Positive or doubtful PCR results were obtained in none of the 120 and two of the 22 colostrum samples, and in eight of the 202 and four of the 27 milk samples Negative PCR results were obtained in the remaining 140 (99%) colostrum samples and 217 (95%) milk samples.<br/

INCOMPLETE-FUSION REACTIONS IN THE N-14+TB-159 SYSTEM AND A SUM-RULE MODEL FOR FUSION AND INCOMPLETE-FUSION REACTIONS

Absolute cross sections for a number of binary processes in the N14+Tb159 reaction have been determined by use of γ-particle coincidence techniques. The data are used to test a "sum-rule model" of complete- and incomplete-fusion reactions. The model assumes the reaction probabilities to be scaled by the available phase space and to be constrained additionally by the entrance-channel angular momentum limitations
