Resources within and between higher education and research institutions are increasingly allocated according to scientific performance. Evaluation exercises and the measurement of research performance take on a new role in this context. Third party research income is a performance indicator which is rather easy to measure and is used in most of the new performance-based evaluation procedures. This
Few attempts have been made to consider the role of individual activities in path dependence. The purpose of this paper is to analyse how local entrepreneurial activities can lead to a break in the cognitive local path. The theoretical framework rests on the literature on path dependence, but focuses mainly on cognitive frames as carriers of path-dependent behaviour. A qualitative case study has b
Context: Large epidemiological studies often collect non-fasting samples, although the reliability of biomarkers may be uncertain. Objective: To explore the reliability and reproducibility of a single measurement of selected biomarkers in a sub-sample of the Malmö Diet and Cancer cohort. Methods: We estimated single- and average-measures intraclass correlation coefficients (ICC) for oxidized (ox)-
This paper discusses the ecological optimisation of municipal waste management systems. The purpose of this paper is to help local decision-makers in designing integrated waste management solutions that are ecologically optimal. The study uses life-cycle assessment (LCA) methodology to build a model and test different waste management scenarios in order to see whether the waste management hierarch
The so-called Parents' Movement is a Russian conservative grassroots mobilization against a presumed Western cultural attack on Russian tradition and sovereignty. The primary target is an ongoing legal implementation of the UN Convention of the Rights of the Child, which is conceived of as a Western feint contrived by hostile global agencies and a Russian fifth column of treacherous NGOs and state
Rib cartilage from growing guinea pigs and epiphyseal cartilage from Beagle puppie were separated into three fractions, representing non-mineralized, low mineralized, and high mineralized, tissue, by centrifuging finely ground material in acetone/bromoform density gradients. Following extraction under dissociative conditions, the proteoglycans were fractionated by density gradient ultracentrifugat
The compressibility and thermal expansion of the cubic silicon nitride (c-Si3N4) phase have been investigated by performing in situ x-ray powder-diffraction measurements using synchrotron radiation, complemented with computer simulations by means of first-principles calculations. The bulk compressibility of the c-Si3N4 phase originates from the average of both Si-N tetrahedral and octahedral compr
Proteoglycan monomers from guinea pig costal cartilage, bovine nasal and bovine tracheal cartilage were observed in the electron microscope after being spread in a monomolecular layer with cytochrome c. The proteoglycan molecule appeared as an extended central core filament to which side chain filaments were attached at various intervals. The molecules from the three sources displayed great ultras
The crystal structures of tert-butyl-tris(trimethylsilyl)silane, Si[C(CH3)3]1[Si(CH3)3]3 (Bu1), and di-ferr-butyl-bis(trimethylsilyl)silane, Si[C(CH3) 3]2[Si(CH3)3]2 (Bu2), at room temperature and at 105 K have been determined by X-ray powder diffraction; the high-pressure behavior for pressures between 0 and 5 GPa is reported. The room-temperature structures have cubic Fm3→m symmetry (Z = 4) with
Fetal guinea-pig epiphyseal chondrocytes were cultured in monolayers and as aggregates in the presence of antimicrotubular agents. Colchicine and vinblastine caused a dissociation of the Golgi complex, in addition to the disappearance of microtubules. Synthesis and secretion of proteoglycans and collagen were studied using radioactive precursors. Colchicine inhibited the synthesis of proteoglycans
An experiment was performed in water resources engineering department laboratory at Lund University of Sweden to investigate the behavior of inclined negatively buoyant jets. Such jets arise when brine is discharged from desalination plants and improved knowledge of their behavior is required for designing discharge systems that cause a minimum of environmental impact on the receiving waters. In t
The turnover in vivo of proteoglycans of guinea pig costal cartilage was investigated using Na2 35SO4 as precursor. Proteoglycans were extracted with guanidine · HCl, at both low and high ionic strength, and purified and fractionated by ultracentrifugation in CsCl gradients under associative and dissociative conditions. The results suggest that the sulfate is incorporated into macromolecules of at
High-pressure X-ray diffraction, Mössbauer, and Raman studies in the antiferromagnetic insulators RFeO3 orthorhombic perovskites (R = Pr, Eu, Lu) disclose an unusual phenomena of a reversible first-order isostructural phase transition around 50 GPa concurring with an abrupt ∼ 5% volume decrease. It is shown experimentally that this transformation concurs with, and is driven by, a high-to-low-spin
Short term cultures were carried out with chondrocytes and tissue fragments from fetal guinea pig epiphyseal cartilage. Proteoglycans were isolated from these cultures and their properties were compared with those of pro-teoglycans from adult hyaline cartilage. It was concluded that the proteoglycans synthesized in culture were essentially similar to those present in cartilage matrix in vivo. The
