Background/Aim: Anastomotic leakage (AL) after anterior resection for rectal cancer occurs in up to 26% of patients. In the last decade, endoscopic vacuum therapy (EVT) has gained interest as a treatment option for AL. This study aimed to compare the clinical success rate of EVT versus transanal drainage (TD) in AL treatment and investigate whether the frequency of bowel continuity differed. Patie

The picture “Iron in clouds” (above) is a photomontage of an idea by El Lissitzky. It has become known for its structurally daring and futuristic aesthetics. El Lissitzky began the project in 1925. Eight identical horizontal skyscrapers were planned to be centrally located in Moscow. Each skyscraper would consist of a flat three-story, 180-meter-wide L-shaped slab raised 50 meters above the street

Background: Voluntary self-exclusion from gambling is a common harm reduction option for individuals with gambling problems. Multi-operator, nationwide self-exclusion services are rare, and a system introduced in the highly web-based gambling market of Sweden is a rare and recent example. However, where web-based casino gambling and web-based betting are the predominate gambling types in those see

The Swedish Secretariat for futures studies was formed in 1973, on the initiative of the Social Democratic government. Initially installed as a part of the Prime Ministers’s Office, futures studies were envisioned as a vital tool for policymaking as well as for stimulating public debate. The present thesis examines the Secretariat from its beginnings up until about ten years later, when it was rel

This study investigates the use of journey mapping as a tool for visualizing theflow of information in home care. Journey mapping is a design method with the purpose of visualizing the interaction of a user and a product or service. It tries to encompass the whole user experience including actions and touch points between user and product, feelings and other related information. Hence, the visuali

We investigated the predictive performance of peripheral quantitative computed tomography (pQCT) measures of both calf muscle density (an established surrogate for muscle adiposity, with higher values indicating lower muscle adiposity and higher muscle quality) and size (cross-sectional area [CSA]) for incident fracture. pQCT (Stratec XCT2000/3000) measurements at the tibia were undertaken in Oste

Recently, research on the edge states of 2D lead halide perovskites (LHPs) has been attracting much attention. The lower-energy edge state (LES) is believed to provide an efficient pathway for the dissociation of photoexcited excitons. However, the mechanism of the LES formation remains controversial, and studies that establish precisely the local electronic properties are lacking. Herein, the fir

Consider the subspace Wn of L2(C, dA) consisting of all weighted polynomials W(z)=P(z)·e-12nQ(z), where P(z) is a holomorphic polynomial of degree at most n- 1 , Q(z) = Q(z, z¯) is a fixed, real-valued function called the “external potential”, and dA=12πidz¯∧dz is normalized Lebesgue measure in the complex plane C. We study large n asymptotics for the reproducing kernel Kn(z, w) of Wn; this depend

Objective: Patients hospitalized with acute coronary syndrome (ACS) in Sweden routinely undergo an echocardiographic examination with assessment of left ventricular ejection fraction (LVEF). LVEF is a measurement widely used for outcome prediction and treatment guidance. The obtained LVEF is categorized as normal (> 50%) or mildly, moderately, or severely impaired (40–49, 30–39, and < 30%, respect

We consider a class of pattern graphs on q≥ 4 vertices that have q- 2 distinguished vertices with equal neighborhood in the remaining two vertices. Two pattern graphs in this class are siblings if they differ by some edges connecting the distinguished vertices. In particular, we show that if induced copies of siblings to a pattern graph in such a class are rare in the host graph then one can detec

The human side of corporate evaluation is frequently neglected in small firm and credit management research. However, it seems to matter both who is being evaluated, especially in smaller companies, and who is making the evaluation. A major reason is that individuals process information in different ways. The purpose of this paper is to develop a conceptual framework for the effects of human diffe

This case study of large-class teaching at a UK university focuses on the place of large-scale lectures in academics’ approaches to teaching, their use by students in their studies, and their relationship to institutional quality assurance policies. The case is a second-year module comprised of 180 students, and it includes two-hour lectures as the primary mode of teaching. The data is drawn from

Cosmology concepts encompass complex spatial and temporal relations that are counterintuitive. Cosmology findings, because of their intrinsic interest, are often reported in the public domain with enthusiasm, and students come to cosmology with a range of conceptions some aligned and some at variance with the current science. This makes cosmology concepts challenging to teach, and also challenging

The present paper explores the TL characteristics of Ag, Cu and Ni doped and co-doped Li2B4O7 nano-composites (NCs). These NCs were synthesized via a Sol–gel process. The influence of doping agents on the optical and TL properties of Li2B4O7 NCs was investigated. Obtained nano-composites were calcined at 700 °C for 8 h. The incorporation of Ag, Cu and Ni impurities in Li2B4O7 lattice has been conf

A demonstration of the theoretically predicted non-abelian properties of Majorana bound states (MBSs) would constitute a definite proof of a topological superconducting phase. Alongside the nontrivial braiding statistics, the fusion rules are fundamental properties of all non-abelian anyons. In this work, we propose and theoretically analyze a way to demonstrate MBS fusion rules in a Majorana sing

Shipbroking and Chartering Practice provides a sound knowledge of the law and economics of international shipbroking and chartering in a practical way that enables the principles described to be applied in everyday situations. The seventh edition has been thoroughly revised to take account of chartering practices, cases and standard forms that have surfaced since the last edition, providing an exc

Mathematical modelling is an indispensable tool to support water resource recovery facility (WRRF) operators and engineers with the ambition of creating a truly circular economy and assuring a sustainable future. Despite the successful application of mechanistic models in the water sector, they show some important limitations and do not fully profit from the increasing digitalisation of systems an

Carrying out long-term search and rescue missions, intelligence, surveillance and reconnaissance, which are carried out with the help of unmanned aerial vehicles (UAVs), overload the operator and reduce the effectiveness of solving the assigned tasks, up to the point of making their implementation impossible. The paper proposes the concept of increasing the speed of the human-machine system based
