Over the past few years many functions of the Ministry for Greenland have been transferred to the Greenland Home Rule Administration. FolIowing the reorganisation of the government after the general election in September 1987 the Ministry for Greenland was abolished and its remaining functions transferred to other ministries. The Geological Survey of Greenland, together with the Greenland Mineral Resources Administration and the Greenland Environment Research Institute were transferred to the Danish Ministry of Energy.

Resumen
In this paper we provide new data about the soil enzyme activity as a biological process, which is an indicator for impacts of factorial combinations of lime and fertilizers applications. Five plots divided into fifteen subplots were sampled for determination of the enzymatic indicators of soil quality, based on the actual and potential dehydrogenase and catalase activities. The research revealed that limed soil samples, in comparison with unlimed ones, resulted in significantly higher soil enzymatic activities (p[0.05) in the upper (0-20 cm), while in the deeper (20-40 cm) layer, only catalas

Since the identification and characterization of iron and sulfur oxidizing bacteria in the 1940s, a rapid progress is being made in minerals engineering based on biological activities. Microorganisms can play a beneficial role in all facets of minerals processing, from mining to waste disposal and management. Some of the applications, such as biologically assisted leaching of copper sulfide ores, uranium ores, and biooxidation of refractory sulfide gold ores, are now established on the scale of commercial processes.

Physiological characteristics of meat-type chicken such as growth traits, serum biochemical metabolites and mineral concentrations, serum enzyme activity, and gut flora were studied by means of 625 day-old chicks which randomly assigned to five treatments with five replicates in a completely randomized design. Four different types of cereal-based diets (wheat, and barley with or without exogenous multi-enzyme supplement) were used as experimental groups and a corn-based diet was also considered to serve as control group. All diets had similar contents of crude protein, energy, and total non-st

Resumen
ABSTRACT The expansion of offshore oil and gas and marine transport activities in the Arctic have raised the level of risk for an oil spill to occur in the Arctic region. Existing technologies for oil spill cleanup in ice-covered conditions are limited and there is a need for improved oil spill countermeasures for use under Arctic conditions. A recent field study has assessed a proposed oil spill response technique in ice-infested waters based on the application of fine minerals in a slurry with mixing by propeller-wash to promote the formation of oil-mineral aggregates (OMA).

Background: Rheumatoid Arthritis [RA] is a chronic systemic disease that affects the functional capacity of the hand due to inflammatory arthritis and joint destruction. RA patients have difficulties with everyday life activities and daily living activities. The prevalence of osteoporosis is estimated to be about twice that of the general population. Dual-energy X-ray absorptiometry (DEXA) is the most precise tool for detecting loss in bone mineral density in RA.

Weathering is a complex process comprising physical disaggregation, chemical and biological decomposition of rocks and minerals transforming complex structure minerals in simpler ones. Hydrolysis of silicates is perhaps the most important process but associated certainly to biological weathering. It is discussed the role ofwaters: activities/concentrations of chemical species, pH, Eh, importance of complexes. Weathering is not only a destructive process.

Gaps by thinning can have different microclimatic environments compared to surrounding areas, depending on the size of the gap. In addition, gaps can play important roles in biological dynamics, nutrient cycling, and seedling regeneration. The impacts of gap size on soil microbial communities and enzyme activities in different soil layers in Chinese pine plantations are not well understood. Here, we created gaps of 45 m2 (small, G1), 100 m2 (medium, G2), and 190 m2 (large, G3) by thinning unhealthy trees in an aged (i.e., 50 years old) monoculture Chinese pine plantation in 2010.
