Skeletal development is heterogeneous. Throughout growth, bone size is more maturationally advanced than the mineral being accrued within its periosteal envelope; before puberty, appendicular growth is more rapid than axial growth; during puberty, appendicular growth slows and axial growth accelerates. We studied women with differing age of onset of anorexia nervosa to determine whether this tempo

The stable isotope of carbon, 13C, has been used in several studies for source characterization of carbonaceous aerosol since there are specific signatures for different sources. In rural areas, the influence of different sources is complex and the application of δ13C for source characterization of the total carbonaceous aerosol (TC) can therefore be difficult, especially the separation between bi

A common problem when studying groundwater contamination in low-income countries is that data required for a detailed risk assessment are limited. This study presents a method for assessment of the potential impact of groundwater contamination by total petroleum hydrocarbons (TPH) in a data-scarce region. Groundwater modeling, using the MODFLOW, was used to simulate regional-scale flow pattern. Th

Investigations over two major tectonic zones in the Hallandsås Horst, Southern Sweden were carried out in connection with a railway tunnelling project. A combination of resistivity imaging, core drilling and geophysical logging was found to provide a good overview of the variation in rock quality and detailed information on the engineering geological characteristics and genesis of the strata. Resi

Popular science The eddy-covariance (EC) method is one of the most important methods to measure gas and energy fluxes between biosphere and atmosphere at ecosystem level. This method was applied above the floor of a boreal forest in Norunda, central Sweden, at 1.5 m height. The objective was to measure the energy and carbon dioxide (CO2) fluxes from the soil and the understory vegetation to the at

Kv. Renen 13 i centrala Varberg är sedan tidigare känt som kraftigt förorenat. På fastigheten har det från slutet av 1800-talet fram till 2003 funnits verksamheter i form av textilindustri som avlösts av finmekanisk verkstadsindustri. Det är framförallt den sistnämnda verksamheten som har orsakat rådande situation med höga halter klorerade lösningsmedel, trikloreten (TCE) och 1,1,1-trikoletan (TCAAn old industry estate, Kv. Renen 13, is located in central Varberg, southwest Sweden, and is known from previous investigations as highly polluted. Pollution started in the late 19th century with textile manufacturing, and in the 1960´s changed into a precision mechanics industry using chlorinated solvents, primary trichloroethene (TCE) and 1,1,1-trichloroethane (TCA), as well as cyanide and meta

In E. coli cells ribosomal small subunit biogenesis is regulated by RNA-protein interactions involving protein S7. S7 initiates the subunit assembly interacting with 16S rRNA. During shift-down of rRNA synthesis level, free S7 inhibits self-translation by interacting with 96 nucleotides long specific region of streptomycin (str) mRNA between cistrons S12 and S7 (intercistron). Many bacteria do not

An experimental and numerical study on mechanical properties, such as strength, elastic modulus, creep and shrinkage, of Self-Compacting Concrete, SCC, and the corresponding properties of Normal Compacting concrete, NC, is outlined in this article. The study included eight mix proportions of sealed or air-cured specimens with water-binder ratio, w/b, varying between 0.24 and 0.80. Half of the mixe

The Arabidopsis MAP kinase 4 (MPK4) substrate MKS1 was expressed in Escherichia coli and purified, full-length, 6x histidine (His)-tagged MKS1 was phosphorylated in vitro by hemagglutinin (HA)-tagged MPK4 immuno-precipitated from plants. MKS1 phosphorylation was initially verified by electrophoresis and gel-staining with ProQ Diamond and the protein was digested by either trypsin or chymotrypsin f
