Filetype
The fillet of the gear tooth is highly stressed in operation; so for heavily loaded gears, the fillet geometry must be controlled. The manufacturer's task is to, within acceptable tolerances, produce the gear to the designer's specifications regardless of the manufacturing method. Most often gear cutting tools are used that work under generating conditions. The tool will form the gear tooth; so to
Background. We aimed to investigate cancer-bereaved youths' opinions and experiences of being told about a parent's imminent death from cancer and of barriers to this communication. Material and methods. This nationwide population-based survey included 622/851 (73%) youths (aged 18 -26) who at age 13-16, 6-9 years earlier had lost a parent to cancer. Results. In total 595 of 610 (98%) of the parti
The paper is concerned with heat integration of a conceptual hydrogen plant connected with a sugar factory. The sugar factory serves as a source of sucrose-containing thick juice for the hydrogen plant, where this feedstock is processed to hydrogen. Moreover, this connection gives an opportunity to utilize waste heat from the sugar factory. Hydrogen is produced by two-stage fermentation, that is,
Non-invasive vascular studies can provide crucial information on the presence, location, and severity of critical limb ischaemia (CLI), as well as the initial assessment or treatment planning. Ankle-brachial index with Doppler ultrasound, despite limitations in diabetic and end-stage renal failure patients, is the first-line evaluation of CLI. In this group of patients, toe-brachial index measurem
The Common Cuckoo Cuculus canorus is an obligate brood parasite and many studies have dealt with egg rejection by host species. However, evidence for ejection of Cuckoo nestlings by host parents has not been reported. Here we describe an observation of a Skylark Alauda arvensis pair that probably ejected a young Cuckoo and subsequently raised their own offspring. This was the only case we detected
It is well known that (some speakers of) Norwegian allow long distance binding, defined here as binding across a finite clause boundary. A number of factors that facilitate long distance binding have also been identified. In the study reported on here, 93 native speakers of Norwegian judged 30 sentences in a web-based questionnaire. The results show that V2 order in the embedded clause reduces the
Traumatic brain injury and bacterial meningitis may at a glance appear as two different disease entities. The host reaction, however, to both trauma and infection involves a strong inflammatory response, with the classical symptomology of rubor, tumor, calor, dolor et functio laesa. Tumor, swelling, will increase the volume within the closed cranial vault, and may thereby raise the intracranial pr
Wider deployment of fiber in the last mile is driven by increased customer needs for high capacity communication. This deployment requires solutions that reduce the operators' OPEX. A cost-efficient fully reliable and accurate monitoring solution supporting fault detection, identification, and localization in different fiber access topologies will be a key part of such solutions. In this article,
Synthesis and decomposition mechanisms of ternary Mg2FeH6 were investigated using in-situ synchrotron radiation powder X-ray diffraction (SR-PXD) and high-pressure differential scanning calorimetry (HP-DSC). Two routes for synthesis of Mg2FeH6 were studied. The first utilizes a ball-milled homogeneous MgH2-Fe powder mixture and the second uses a mixture of Fe and Mg formed by decomposition of the
Rural depopulation is a concern in many countries, and various policy initiatives have been taken to combat such trends. This article examines whether hidden potential for rural population growth can be found in Sweden. If such potential exists, it implies that the development prospects for many rural areas are not as unpromising as they may seem today. If not, rapid rural depopulation can be expe
Prostate-specific antigen (PSA) and human glandular kallikrein 2 (hK2) are secreted by the prostate into seminal plasma and through leakage into blood. This leakage increases rapidly in prostate disease, and PSA is used worldwide as a marker of prostate cancer. PSA is activated in vitro by hK2, and cleaves the semenogelins in semen, which releases motile sperm, and low levels of PSA have been asso
Rheumatoid arthritis (RA) is a systemic disease, with an increased risk of co-morbidity from cardiovascular disease (CVD), in particular among those with severe disease. Environmental risk factors are of potential interest for both prevention and treatment of RA. Our aim was to examine changes in the occurrence of CVD over time and, using immunohistochemistry, study markers of inflammation in vas
Objective Guidelines on histopathological techniques and reporting for adult and paediatric gastrointestinal neuromuscular pathology have been produced recently by an international working group (IWG). These addressed the important but relatively neglected areas of histopathological practice of the general pathologist, including suction rectal biopsy and full-thickness intestinal tissue. Recommend
Background To evaluate the effects of a case management intervention for frail older people (aged 65+ years) by cost and utility. Materials and methods One hundred and fifty-three frail older people living at home were randomly assigned to either an intervention (n = 80) or a control group (n = 73). The 1-year intervention was carried out by nurses and physiotherapists working as case managers, w
The promoting effect of SO2 on the activity for methane oxidation over platinum supported on silica, alumina and ceria has been studied using a flow-reactor, in situ infrared spectroscopy and in situ high-energy X-ray diffraction experiments under transient reaction conditions. The catalytic activity is clearly dependent on the support material and its interaction with the noble metal both in the
