BACKGROUND We present data from a DNA taxonomy register of the abyssal Cnidaria collected as part of the Abyssal Baseline (ABYSSLINE) environmental survey cruise 'AB01' to the UK Seabed Resources Ltd (UKSRL) polymetallic-nodule exploration area 'UK-1' in the eastern Clarion-Clipperton Zone (CCZ), central Pacific Ocean abyssal plain. This is the second paper in a series to provide regional taxon...
The reaction of [Ru(L)2(H2biim)](ClO4)2 [L1 = 2,2¢-bipyridine (bpy) or L2 = 2-(phenylazo)pyridine (pap) and H2biim = 2,2¢-biimidazole] with Au(tht)Cl (tht = tetrahydrothiophene) in presence of base in methanol produced a terametallic cationic complex [{Ru(L)2(biim)}<s...
The ocean is extremely rich in mineral resources. To cope with the shortage of land resources, countries are focusing on development deep-sea mining technology. Owing to its superior traction performance, polymetallic nodule collector (DPNC) has become preferred solution for mining. This paper proposes a dynamic calculation model address shortcomings classical static consideration variation rul...
The generality of relationships between soil net nitrogen (N) mineralization, aboveground N cycling, and aboveground net primary production (ANPP) for temperate forest ecosystems is unclear. It is also not known whether these variables and their relationships differ between evergreen and deciduous forests, or across soil types. To address these questions we compiled data on annual rates of in s...
This review attempts to summarize the findings made available by the literature on the mineralization of bone. The types of bone, their structures and compositions, the nature and organization of organic and inorganic matter, the organic-inorganic relationships, and the mineralization mechanism itself, are the main topics of the present review. As in other hard tissues, bone mineralization occu...
The study area is located at northeast of Neyshabour in the Khorasan Razavi Province, northwest Arghash Gold Mine. The rocks of area are composed of polutonic to subvolcanic units with acid- intermediate in composition. They consist of granodiorite, diorite and granite. Alteration zones are: propylitic, sericitic, silicified and argillic. In the study area, mineralization is divided into two ty...
Rats maintained for 8 months on a level of warfarin sufficient to decrease the vitamin K-dependent protein of bone (bone Gla protein) to 2% of normal have an excessive mineralization disorder characterized by complete fusion of the proximal tibial growth plate and cessation of longitudinal growth. The general features of this abnormality resemble the fetal warfarin syndrome in humans, a disorde...
The potential of fluorinated tetraolate as a ligand for the synthesis of polynuclear metal complexes has been demonstrated.
