This paper describes a method to minimize bearing forces as well as bearing and housing mass for a multistage gear reduction. This is done by finding the optimum dog-leg angles for the stages while leaving other aspects of the design unaltered. The optimization is demonstrated first for spur gears, and then for helical gears typically used in electric vehicles. A numerical example shows how bearin

Introduction: Many studies have assessed the prevalence of alcohol consumption in Iran. In this study, we investigated the prevalence of alcohol consumption in different groups. Material and Methods: We searched international and databases including PubMed, Web of Science, Scopus and we searched two main Farsi-language index databases including Scientific Information Database (SID) and the Irandoc

Human papillomaviruses (HPV) are epitheliotropic DNA tumor viruses that are prevalent in the human population. A subset of the HPVs termed high-risk HPVs (HR-HPVs) are causative agents of anogenital cancers and head-and-neck cancers. Cancer is the result of persistent high-risk HPV infections that have not been cleared by the immune system of the host. These infections are characterized by dysregu

Limonene and linalool are among the most common fragrance terpenes used in everyday products. They are pre-haptens, forming hydroperoxides (Lim-OOHs, Lin-OOHs) upon oxidation and inducing frequent positive patch test reactions in patients with dermatitis, and yet they are not routinely tested in Europe. This review evaluates current patch testing with Lim-OOHs and Lin-OOHs by asking whether hydrop

Economic geographers have studied emerging industries in regions from various perspectives, such as life cycle, evolutionary economic geography and systemic approaches. However, so far they have insufficiently conceptualized the effects of institutional structures on new industry emergence. This special issue on ‘Emerging Industries: Institutions, Legitimacy and System Building’ therefore shows re

Semi-arid and arid ecosystems are important for the global C cycle. Despite this, it remains unclear how organic matter fractions vary across latitudinal gradients, and what drives this variation, in dry ecosystems. In this study, we sampled soils from 100 sites across a latitudinal gradient in the dry valleys of southwestern China to explore the latitudinal patterns of light fraction organic matt

Background: Prophylactic lightweight mesh in the sublay position reduced the cumulative incidence of parastomal hernia (PSH) after cystectomy with ileal conduit diversion in a randomised controlled trial.Objective: To investigate whether the use of prophylactic mesh is cost-effective in comparison to no mesh from the health care provider perspective.Design setting and participants: Data on health

The complex genetic architecture of type-2-diabetes (T2D) includes gene-by-environment (G×E) and gene-by-gene (G×G) interactions. To identify G×E and G×G, we screened markers for patterns indicative of interactions (relationship loci [rQTL] and variance heterogeneity loci [vQTL]). rQTL exist when the correlation between multiple traits varies by genotype and vQTL occur when the variance of a trait

BACKGROUND AND AIMS: We aimed to investigate the association between protein intake and risk of inflammatory bowel disease (IBD) in the European Prospective Investigation into Cancer and Nutrition.METHODS: 413 593 participants from eight European countries were included. Dietary data were collected at baseline from validated food frequency questionnaires. Dietary data were calibrated to correct er

Background: Information and communication technology (ICT) has been proven to have effect in terms of providing alternative ways to deliver rehabilitation services. The intention with this paper is to serve as a foundation for discussions regarding the future development, design, and delivery of home-based rehabilitation, including ICT. Aim: To reflect on and discuss the possibilities and challeng

Introduction: Radiographic progression-free survival (rPFS) by Prostate Cancer Working Group (PCWG) criteria is a radiographic endpoint. The automated bone scan index (aBSI) quantifies osseous disease burden on bone scintigraphy as a percentage of total skeletal weight. Using the aBSI, we sought to quantify increase in tumor burden represented by PCWG progression criteria, and to determine the int

Introduction: The B-Natural study is a multicentre, multinational, observational study of haemophilia B (HB) designed to increase understanding of clinical manifestations, treatment and quality of life (QoL). Aim: To characterise and compare QoL in HB across disease severity groups and individuals with inhibitors to identify gaps in treatment. Methods: A total of 224 individuals from 107 families

Severe joint injuries often involve cartilage defects that propagate after mechanical loading. The propagation of these lesions may contribute to the development of post-traumatic osteoarthritis (PTOA). However, the mechanisms behind their propagation remain unknown. Currently, no numerical predictive methods exist for estimating crack propagation in cartilage under cyclic loading, yet they would

Abstract: Breast density is an independent risk factor for the development of breast cancer and also decreases the sensitivity of mammography for screening. Consequently, women with extremely dense breasts face an increased risk of late diagnosis of breast cancer. These women are, therefore, underserved with current mammographic screening programs. The results of recent studies reporting on contra

The existing information supports the use of this material as described in this safety assessment. 2,6-Nonadienenitrile was evaluated for genotoxicity, repeated dose toxicity, reproductive toxicity, local respiratory toxicity, phototoxicity/photoallergenicity, skin sensitization, and environmental safety. Data show that 2,6-nonadienenitrile is not genotoxic. Data on read-across analog E- and Z-2(+
