Airborne wear particles originating from disc brakes are one important contributor to the concentration of airborne particles in urban environments. It is therefore of interest to improve the knowledge of these particles. The purpose of this article is to investigate the concentration and size distribution of the airborne wear particles generated from the contact between a low-metallic pad materia

The activation of the kallikrein-kinin system is thought to be one of the pathophysiological factors in acute pancreatitis. A radioimmunoassay for porcine, pancreatic tissue kallikrein was developed and used to measure levels in normal plasma and peritoneal fluid and in experimental, bile-induced (group A) and bile trypsin-induced (group B) acute pancreatitis in the pig. Normal porcine plasma and

The management of non-muscle-invasive bladder cancer (NMIBC) has evolved from the first reports on bladder endoscopy and transurethral resection to the introduction of adjuvant intravesical treatment. However, disease recurrence and progression remain an ongoing risk, placing a heavy burden on healthcare resources and on patients’ quality of life. Deeper understanding of the molecular basis of the

Prospective studies using video-recordings of patients during mechanical ventilator treatment (MVT) while conscious have not previously been published. The aim was to describe patients' statements, communication and facial expressions during a video-recorded interview while undergoing MVT. Content analysis and hermeneutics inspired by the philosophy of Gadamer were used. The patients experienced a

Background: Birds that forage while covering distance during migration should adjust traveling behaviors as the availability of foraging habitat changes. Particularly, the behavior of those species that depend on bodies of water to find food yet manage to migrate over changing landscapes may be limited by the substantial variation in feeding opportunities along the route. Methods: Using GPS tracki

We present a relativistic and model-independent method to derive structure-dependent electromagnetic finite-size effects. This is a systematic procedure, particularly well-suited for automation, which works at arbitrarily high orders in the large-volume expansion. Structure-dependent coefficients appear as zero-momentum derivatives of physical form factors which can be obtained through experimenta

Nickel-based superalloys are known to be difficult to machine. These alloys are generally machined with cemented carbide tools under low productivity process conditions. Superhard polycrystalline cubic boron nitride (PcBN) tooling offers the possibility of increased production rates, however, a thorough understanding of the material performance and degradation is required before a transition from

The prothrombin gene G20210A mutation and the platelet glycoprotein IIIa polymorphism PlA2 have been shown to be associated with thromboembolic disease. We wondered if mutations were overrepresented in patients with central retinal vein occlusion. We studied 129 consecutive patients with a history of central retinal vein occlusion. We analysed for the prothrombin gene G20210A mutation and the plat

Urban tourism depends on the place specific qualities of destinations. In many cities, climate change poses a threat to these qualities, through increasing risk of excessive heat, draught and flooding. Cities need to adapt to reduce these risks. One way of doing this is to improve their green infrastructure. Urban forests, parks, rivers and wetlands may help reduce the effects of climate change in

The Cuban university has strengthened its scientific connections with the various social, political, and productive stakeholders. Technology transfer policies have been shaped by historical-economic-social contexts, public policies, and endogenous transformations. Indeed, technology transfer policy frameworks are part of a broader legislative framework for science, technology, and innovation in ma

Introduction: Antibiotics for acute uncomplicated diverticulitis (AUD) have been questioned in several studies. Thus, it is of value to identify risk factors for recurrence and complications to identify the best strategy for treatment. The aim was to investigate risk factors for recurrence and complications within at least 1 year after hospitalization for AUD. Methods: This is a retrospective stud

Importance: Genetic risk factors are known to play a role in the etiology of psychotic experiences in the general population. Little is known about whether these risk factors interact with environmental risks for psychotic experiences. Objective: To assess etiological heterogeneity and exposure to environmental risks associated with psychotic experiences in adolescence using the twin design. Desig

Most countries in Sub-Saharan Africa have made great strides towards more accessible and higher quality schooling and medical systems in recent years. Despite this, education and health care in Africa lag behind other developing regions and large inequalities in educational levels and health care access remain across countries, subnational regions, and gender. Cameroon, in west-central Africa, wit
