New printing technology and pricing

This case study analyzes five Swedish printing houses' pricing with respect to their investments in new printing technology. The new printing technology made it possible for the printing houses to market new products and services to meet the demand for shorter delivery times and full service solutions. Although this demand was apparent, the printing houses' opportunities to capitalize on their inv

The battleground of two Infections and a cancer: Human Papilloma Virus, premalignant lesions of the cervix and their interaction with Human Immunodeficiency Virus in southwestern Nigeria

Popular Abstract in English An increased risk of pre-cancer lesions of the cervix among HIV-infected women, and the positive impact of HIV treatment on its outcome has been reported globally. However there is paucity of information from west Africa with genetically distinct viral strains. Considering that HIV strains differ in the rate and pattern of HIV disease progression, a different outcome isBackground: The highest numbers of HIV-infected women are in sub- Saharan Africa, where the natural progression of HIV disease in the absence of treatment results in death before the onset of invasive cervical cancer. With improved access to treatment, several studies outside West Africa demonstrated an increased risk of pre-invasive cervical lesions among HIV-infected women and the positive impac

Machine Learning Algorithms for Improved Glaucoma Diagnosis

Primary open angle glaucoma, one of the leading causes of blindness in the world, constitutes a slow progressing condition characterized by damage to the optic nerve and retinal nerve fibre layer, and results in visual field defects afflicting the visual function. Highly specific and sensitive diagnostic tests able to detect the clinically significant glaucomatous changes in the structure of the n

Treatment of Critical Limb Ischaemia

Recommendations stated in the TASC II guidelines for the treatment of peripheral arterial disease (PAD) regard a heterogeneous group of patients ranging from claudicants to critical limb ischaemia (CLI) patients. However, specific considerations apply to CLI patients. An important problem regarding the majority of currently available literature that reports on revascularisation strategies for PAD

Reconstitution of water channel function and 2D-crystallization of human aquaporin 8.

Among the thirteen human aquaporins (AQP0-12), the primary structure of AQP8 is unique. By sequence alignment it is evident that mammalian AQP8s form a separate subfamily distinct from the other mammalian aquaporins. The constriction region of the pore determining the solute specificity deviates in AQP8 making it permeable to both ammonia and H(2)O(2) in addition to water. To better understand the

Mitogenomic relationships of placental mammals and molecular estimates of their divergences.

Molecular analyses of the relationships of placental mammals have shown a progressive congruence between mitogenomic and nuclear phylogenies. Some inconsistencies have nevertheless persisted, notably with respect to basal divergences. The current study has aimed to extend the representation of groups, whose position in the placental tree has been difficult to establish in mitogenomic studies. Both

Fabrication and improvement of nanopillar InGaN/GaN light-emitting diodes using nanosphere lithography

Surface-patterning technologies have enabled the improvement of currently existing light-emitting diodes (LEDs) and can be used to overcome the issue of low quantum efficiency of green GaN-based LEDs. We have applied nanosphere lithography to fabricate nanopillars on InGaN/GaN quantum-well LEDs. By etching through the active region, it is possible to improve both the light extraction efficiency an

Use of the Cone Calorimeter and ConeTools software for development of innovative intumescing graphite systems

The Cone Calorimeter test method has been one of the most used small-scale fire test method for years now and is at present widely spread over the world. In contrast to many other fire test methods, the Cone Calorimeter provides a range of data with sound scientific basis, which allows a wide range of applications. It can be used for modelling and also for enhanced product development. This paper

Knee injuries and their consequences – the impact of impact

Anterior cruciate ligament (ACL) injuries are common, severe knee injuries that result in a high risk of developing knee osteoarthritis (OA) in the affected individuals. As proof of high impact forces applied to cartilage and bone at the time of injury, traumatic bone marrow lesions and osteochondral fractures, located predominantly in the lateral tibiofemoral compartment, are commonly associated

Direct observation of atomic scale surface relaxation in ortho twin structures in GaAs by XSTM

We have studied the (110) GaAs surface of a structure containing ortho twins by cross-sectional scanning tunnelling microscopy and we have compared the experimental results with ab initio density functional theory calculations and STM simulations. Both experimentally and theoretically we find that the surface of different twin crystallites are significantly displaced with respect to each other, pa

Reduced expression of the polymeric immunoglobulin receptor in pancreatic and periampullary adenocarcinoma signifies tumour progression and poor prognosis

The polymeric immunoglobulin receptor (pIgR) is a key component of the mucosal immune system that mediates epithelial transcytosis of immunoglobulins. High pIgR expression has been reported to correlate with a less aggressive tumour phenotype and an improved prognosis in several human cancer types. Here, we examined the expression and prognostic significance of pIgR in pancreatic and periampullary

The role of landscape structure in determining palynological and floristic richness

The associations between floristic and palynological richness and landscape structure were studied based on modern pollen-vegetation data from a patchy cultural landscape in southern Estonia (northern temperate vegetation zone). Nine study sites (small lakes and their surrounding vegetation) represent land cover gradient from closed forest to semi-open vegetation. Floristic richness (number of spe

Focus is placed in reviewing the scientic knowledge that concerns the honey-bee by discussing its cognitive and ethical categories and its in uence in nature conservation, mainly centred in the EU. Results indicate that scientic knowledge plays a fundamental ro

Direct visual evidence for the chemical mechanism of surface-enhanced resonance Raman scattering via charge transfer: (II) Binding-site and quantum-size effects

We describe quantum-size and binding-site effects on the chemical and local field enhancement mechanisms of surface-enhanced resonance Raman scattering (SERRS), in which the pyridine molecule is adsorbed on one of the vertices of the Ag-20 tetrahedron. We first investigated the influence of the binding site on normal Raman scattering (NRS) and excited state properties of optical absorption spectro

Control Structures for Low-Emission Combustion in Multi-Cylinder Engines

Traditionally, heavy-duty diesel engines have high efficiencies but also high emissions of NOx and soot particles. New engine concepts show the potential to retain diesel-like efficiencies while reducing emissions by forming a completely or partially homogeneous mixture of fuel and air prior to ignition through compression. The long ignition delay required to form this homogeneous mixture makes th

Functionalized nanoparticles in aqueous surroundings probed by X-ray photoelectron spectroscopy

In this paper we present the first core-level photoelectron spectroscopic study of solid nanoparticles in liquid water. The particles are SiO2-based with an average diameter of 70 nm and functionalized with carboxylic groups. Despite that the sample is very dilute, we show that it is possible to obtain reasonable photoemission signal containing chemical information about both the ligands and the o
