This work introduces the development and application of a multi-goal evaluation procedure for assessing sets of remedial options that have previously been found technically suitable for managing a certain contaminated site. The construction of this decision support tool, in the form of a balanced scorecard, has followed a multi-attribute conception of the contaminated sites problem, identifying the most critical aspects considered by all stakeholders involved in contaminated sites management decisions. The developed tool has been checked in its formulation and application against an export benchmark of an Austrian remediation project. The performed evaluation allowed to identify and suggest a remedial option that best fitted the expectations of all stakeholders involved in the project. Furthermore, through the accomplishment of a sensitivity analysis it has been demonstrated that the system is stable and robust in terms of the chosen elicitation schemes, and that the preferences of the different stakeholders are influencing factors on the final result. The results and conclusions of this work present the benefits of implementing the developed balanced scorecard as a tool for supporting decision making in contaminated sites remediation projects.  相似文献   

霉菌毒素结合制剂在营养策略中所扮演的角色     

Karl A.Dawson 《中国家禽》2001,23(9):32-35

1 简介霉菌毒素是霉菌代谢的次级产物，这种物质很可能在饲料的制造与贮存过程中污染到饲料。目前已知至少有300种以上霉菌代谢产物会使动物及人类中毒，全世界谷物中有25％受到霉菌毒素的污染，而且达到可量测的浓度。在这些毒素中，已知有很多种物质明显影响动物的健康，对动物生产造成重大影响。2 霉菌毒素的产生在自然状态下霉菌毒素的产生是一个全球性问题，但是世界上某些特定地区霉菌毒素产生的情形比其他地区频繁。在较冷或气候较温和的地区，例如加拿大、美国的北部及多数欧洲国家，黄曲霉毒素并不是主要问题，除了进口的饲料原料…  相似文献

Indirect hemagglutination for Eperythrozoon suis detection in experimentally and spontaneously infected swine   总被引：5，自引：0，他引：5  

G Baljer  K Heinritzi  L Wieler 《Zentralblatt für Veterin?rmedizin. Reihe B. Journal of veterinary medicine. Series B》1989,36(6):417-423

Ten splenectomized and non-splenectomized pigs were experimentally infected with E. suis bearing red blood cells in order to determine the antibody response. All animals were monitored for antibody titer by indirect hemagglutination over a period of 80-290 days postinfection. Latent E. suis infection only yielded a detectable antibody titer in one pig. Acutely infected pigs had a titer ranging up to 1:640. Maximum antibody response lasted only 2 months and dropped below the level of detection of our assay within 2 to 3 months. At this time, the clinical symptoms could reappear and antibodies were again detectable. However, no booster effect was observed with this second outbreak. We also determined the antibody frequency in 138 pigs from 16 herds in Southern Germany. Pigs from only 4 out of 6 clinically positive herds had antibody titer against E. suis. 20 out of 78 pigs of the clinical positive herds demonstrated a detectable E. suis antibody titer. In 10 herds that were asymptomatic and presumed uninfected all 80 pigs were serologically negative for E. suis.  相似文献   

Detection of inhibitors in swine urine with MICUR-BT]     

K Heinritzi  I Hartel  W Bollwahn 《Tier?rztliche Praxis》1992,20(6):595-599

The immersible culture medium MICUR-BT used in human medicine for the detection of antimicrobial substances in the urine was tested for its suitability in pigs. In in-vitro tests, 15 pure antibiotic substances, 2 pure substance mixtures as well as 5 veterinary injection preparations with no direct antimicrobial effect were checked. The agar perforation test was used as a reference procedure. In a total of 65 pigs the detectability of 9 pure antibiotic and chemotherapeutic agents, 2 pure substance mixtures as well as 5 veterinary drugs with no direct antimicrobial effect was tested after oral or parenteral application. In the in-vivo tests the MICUR-BT test turned out to be more reliable than the agar perforation test. In 76.9% of the untreated pigs below 30 kg b.w. the MICUR-BT-test showed an antimicrobial effect. Such effects were reduced by 38.3% in the reference procedure.  相似文献   

Lactic acid bacteria for mink. Colonization and persistence of Enterococcus faecium Cernelle 68 in the digestive tract of mink.     

Karl Pedersen  Mogens Jorgensen 《Acta veterinaria Scandinavica》1992,33(1):95-103

A method was developed to follow a lactic acid bacterial strain, Enterococcus faecium Cernelle 68, with respect to adhesion, multiplication, colonization, and persistence in the digestive tract of mink. Also the spread of the strain in the cage was examined. When adding 5 x 10(9) c.f.u. of a rifampicin resistant mutant per kg feed, high viable counts were registered throughout the digestive tract, apart from the oesophagus. Counts were increasing in the aboral direction, suggesting some multiplication in the intestine. It was possible to detect the strain in the intestinal tract 4 days after discontinuation of administration. Neither culture nor scanning electron microscopy gave evidence to suggest that E. faecium Cernelle 68 adhered to the mucosa. The spread of the E. faecium strain was observed in the environment. Counts of E. coli, lactobacilli, staphylococci, and clostridia were low, and none of these bacteria were constant findings.  相似文献

Infectious salmon anaemia (ISA) epidemiology in Norway     

Ivar V  gsholm  Hans Olav Djupvik  Finn Victor Willumsen  Anne Marie Tveit  Karl Tangen 《Preventive veterinary medicine》1994,19(3-4):277-290

A case-control study is reported of 57 holdings (holdings in which salmon are raised in sea-water) with infectious salmon anaemia (ISA) and 61 holdings without ISA, together with a follow-up study of the control holdings, during 1988–1990. Generally the identified risk factors implied poor biosecurity since passive transmission (proximity to other ISA holdings) and active transmission (management practices which increased exposure to foreign biological material) were found to be major risk factors. The findings indicated that ISA was spread by infected live salmon or infected biological material i.e. animal waste or discharge from normal operations and slaughter. The findings also indicated that decreased host resistance could be important, but these results could be also be explained by a misclassification bias. Moreover, the findings indicate that a prompt eradication policy and improved biosecurity would be important means of controlling ISA.  相似文献
