In 1987, the curriculum of Environmental Sciences was introduced at Swiss Federal Institute of Technology Zurich ([Eidgenössische Technische Hochschule Zurich], ETHZ). The curriculum was motivated by demands and pressures that characterize our post-industrial age, particularly the necessity to understand complex environmental problems and assess their long term impacts from an interdisciplinary...

Heavy metals play an important role in the homeostasis of living cells. However, these elements induce several adverse environmental effects and toxicities, therefore seriously affect cells organisms. In recent years, some heavy metal pollutants have been reported to cause harmful on crop quality, thus both food security human health. For example, chromium, cadmium, copper, lead, mercury were d...

During the spread of pandemic disease, dental practice come across highest risk corona virus infection by exposure from patient saliva, aerosols generation during procedure, blood contamination oral surgical procedure. This can be transmitted symptomatic to asymptomatic individual through aerosol spread, saliva contamination. Due its ability airborne transmission, so generated natural activity ...

The earlier observed pronounced hypogammaglobulinemia in germfree rats of different ages has been confirmed. Using an immunologic technique the concentration of immunologic gamma globulins were found to vary between 10 and 15 per cent of the values observed in ordinary rats. Upon contamination of germfree rats with the normal microbial flora a pronounced lag phase was noted before the gamma glo...

Although core, animal-reminder, and contamination disgust are viewed as distinct "types" of disgust vulnerabilities, the extent to which individual differences in the three disgust domains uniquely predict contamination-related anxiety and avoidance remains unclear. Three studies were conducted to fill this important gap in the literature. Study 1 was conducted to first determine if the three t...

The contamination of 15 ground water resources of a selected region earmarked for the emergency supply of population has been monitored. The resources have been selected on the basis of previous assessment of natural conditions and the exploitation of territory in their surroundings and infiltration area. Two resources out of 15 have been excluded from further exploitation, because they have no...
