Birationality of \'etale morphisms via surgery
We use a counting argument and surgery theory to show that if is a
sufficiently general algebraic hypersurface in , then any local
diffeomorphism of simply connected manifolds which is a
-sheeted cover away from has degree or (however all
degrees are possible if fails to be a local diffeomorphism at even
a single point). In particular, any \'etale morphism of
algebraic varieties which covers away from such a hypersurface must be
birational.Comment: 17 pages. Replaced to add further references and make language more

Lessons learnt from a process evaluation of an exercise intervention in patients treated with autologous stem cell transplantation
Influence of dietary mannanoligosaccharides on histological parameters of the jejunal mucosa and growth performance of broiler chickens
The trial involved 480 Hubbard Classic broiler chicks which were from either mannanoligosaccharide (MOS) fed breeder flock (Bio-Mos, Alltech Inc. USA at level of 1 kg/t) or control fed breeder flock (without MOS). Three groups with four replicates per treatment were formed: control fed breeders/control fed broilers (C/C); MOS fed breeders/control fed broilers (BM/C) and MOS fed breeders/MOS fed broilers (BM/BM). All chicks were fed the same basal diet, except for the inclusion of Bio-Mos (1, 0.75 and 0.5 kg/t in the starter, grower and finisher diet, respectively). The results showed a significant improvement (p<0.05) in the body weight gain with the addition of Bio-Mos in broiler feed. Feed conversion ratio was improved by 0.03 points, but the difference was not significant (P>0.05). The gut morphology examination showed that chick origin (chicks that originated from Bio-Mos fed breeders or control fed breeders) did not influence the morphological parameters of the jejunum in the broiler chickens, but addition of Bio-Mos directly to the broiler feed had a significant influence on the gut morphology and played an important role in processes of digestion and absorption, leading to improved performance.Key words: Broiler, mannanoligosaccharides, growth, jejunum, histology
Perceived usability and use of custom-made footwear in diabetic patients at high risk for foot ulceration
Data-driven directions for effective footwear provision in diabetic patients with a history of foot ulceration
Design of the EXercise Intervention after Stem cell Transplantation (EXIST) study: a randomized controlled trial to evaluate the effectiveness and cost-effectiveness of a individualized high intensity physical exercise program on fitness and fatigue in patients with multiple myeloma or (non-) Hodgkin's lymphoma treated with high dose chemotherapy and autologous stem cell transplantation
Return to work experiences of patients treated with stem cell transplantation for a hematologic malignancy
Purpose This qualitative study aimed to identify hematopoietic stem cell transplantation (HSCT) survivorsâ (1) work perceptions; (2) barriers to and facilitators of return to work (RTW); and (3) possible solutions to improve RTW. Method Fifteen patients treated with HSCT 1â5 years ago participated in face-to-face semi-structured interviews. Interviews were analyzed following the steps of thematic content analyses. Results RTW was often characterized as a complex and prolonged trajectory, and it was frequently incomplete in working hours, tasks, and/or responsibilities. Work perceptions varied between patients; most valued work as positive, but some also reported a decline in work capacity and/or in importance. Perceived barriers included the duration and side effects of cancer treatment, the presence of comorbidity and poor health before diagnosis, having difficulties commuting and doing household tasks. Perceived facilitators were financial incentives, keeping in touch with the workplace, support of other patients and family, and looking after oneâs health. Proposed solutions to improve RTW included discussing RTW at the hospital, enhanced employer support, improved accessibility of rehabilitation programs, and more information about the consequences of being sick-listed. Conclusions Many HSCT survivors value work as important and they are motivated to RTW. Insight in work perceptions, RTW barriers, and solutions might help researchers, healthcare professionals, and employers to develop and/or tailor individualized multidisciplinary care to facilitate RTW

Chemical and chemometric methods for halal authentication of gelatin: an overview
The issue of food authenticity has become a concern among religious adherents, particularly Muslims, due to the possible presence of nonhalal ingredients in foods as well as other commercial products. One of the nonhalal ingredients that commonly found in food and pharmaceutical products is gelatin which extracted from porcine source. Bovine and fish gelatin are also becoming the main commercial sources of gelatin. However, unclear information and labeling regarding the actual sources of gelatin in food and pharmaceutical products have become the main concern in halal authenticity issue since porcine consumption is prohibited for Muslims. Hence, numerous analytical methods involving chemical and chemometric analysis have been developed to identify the sources of gelatin. Chemical analysis techniques such as biochemical, chromatography, electrophoretic, and spectroscopic are usually combined with chemometric and mathematical methods such as principal component analysis, cluster, discriminant, and Fourier transform analysis for the gelatin classification. A sample result from Fourier transform infrared spectroscopy analysis, which combines Fourier transform and spectroscopic technique, is included in this paper. This paper presents an overview of chemical and chemometric methods involved in identification of different types of gelatin, which is important for halal authentication purposes
