Thromboembolism is a serious complication of surgery and prophylaxis is therefore recommended. This study examines a new aspect of the problem, the incidence of thromboembolism after day-case surgery. From 1982 to 1992, 2281 patients underwent day-case repair for inguinal hernia management. Hospital admission for thromboembolism within the first 30 days after surgery was identified by computer lin

Cryptocurrencies are growing at a rapid pace. It is well established that the mining operation fueling the cryptocurrency Bitcoin consumes a significant amount of energy. This study aims to determine if there is an alternative to the consensus model, maintaining security, integrity, and decentralization. It includes a deep dive into the Bitcoin network and the consensus model Proof of Work (PoW ).

To date, very little is known about the demography of European settlers in South Africa, since descriptions have been based on Ross's 1975 calculations of a small sample of 300 observations in the Cape Colony. In this paper we provide a broader and deeper account, using a dataset drawn from the Genealogical Institute of South Africa (2008) that includes information on 401,602 observations of settl

We exploit the 7 Ms Chandra observations in the Chandra Deep Field-South (CDF-S), the deepest X-ray survey to date, coupled with CANDELS/GOODS-S data, to measure the total X-ray emission arising from 2076 galaxies at 3.5 ≤ z < 6.5. This aim is achieved by stacking the Chandra data at the positions of optically selected galaxies, reaching effective exposure times of ≥109s.We detect significant (>3.

This article updates our previous Stroke Gene Panels (SGP) from 2017. Online Mendelian Inheritance in Man and PubMed were searched. We divided detected genes into two SGP groups, SGP1: genes reported in at least one person with stroke and associated with one or more clinical subgroups: large artery atherosclerotic, large artery non-atherosclerotic (tortuosity, dolichoectasia, aneurysm, non-atheros

AlxGa1−xN ternary alloys are emerging ultrawide band gap semiconductor materials for high-power electronics applications. The heat dissipation, which mainly depends on the thermal conductivity of the constituent material in the device structures, is the key for device performance and reliability. However, the reports on the thermal conductivity of AlxGa1−xN alloys are very limited. Here, we pr

Objectives: Smoking cessation programmes in which groups of smokers have the opportunity to learn behavioural techniques and benefit from mutual support for quitting are widely available. The aim of this review is to determine the effectiveness of smoking cessation programmes delivered in a group format, for helping smokers achieve long-term smoking cessation. Search strategy: TheTobacco Addicitio

This article represents the proceedings of a symposium at the 2000 ISBRA Meeting in Yokohama, Japan. The chairs were Claudia Spies and Hanne Tønnesen. The presentations were (1) Relevance of alcohol misuse in surgical patients, by Hanne Tønnesen; (2) Diagnosis of alcohol abuse and alcohol dependence, by Sven Andreasson; (3) Diagnosis of acute alcohol misuse, by Anders Helander; (4) Preoperative in

Alcohol abusers have a threefold increased risk of post-operative morbidity after surgery. The most frequent complications are infections, cardiopulmonary insufficiency, and bleeding episodes. Pathogenesis is suppressed immune capacity, subclinical cardiac dysfunction, and haemostatic imbalance. The economic implications of alcohol abuse in surgical patients are tremendous. Interventional studies

This study reports an impact evaluation carried out for a large-scale research infrastructure, the Brazilian Sirius Synchrotron Light Source, one of two fourth-generation synchrotron light sources in the world. We focus on the economic impacts and spillovers resulting from highly qualified procurements presented to different types of suppliers who participated in the design and construction proces

Context. The Gaia-ESO Survey (GES) is a large public spectroscopic survey that has collected, over a period of six years, spectra of ~105 stars. This survey provides not only the reduced spectra, but also the stellar parameters and abundances resulting from the analysis of the spectra. Aims. The GES dataflow is organised in 19 working groups. Working group 13 (WG13) is responsible for the spectral

By applying one of the largest datasets on ESG ratings to date with around 8000 companies included during the sample period between 2006-2021. This paper investigates the increasingly popular link between firms’ social and financial performance and the potential abnormal returns to be found using ESG investment strategies. To examine this relationship, a series of portfolios are constructed based

Materials with a kagome lattice structure display a wealth of intriguing magnetic properties due to their geometric frustration and intrinsically flat band structure. Recently, topological and superconducting states have also been observed in kagome systems. The kagome lattice may also host a "breathing"mode that leads to charge density wave (CDW) states, if there is strong electron-phonon couplin

Purpose: To examine how core values can be concretely transformed in the physical stores in order to help with the creation of favorable brand associations and the shaping of the brand image. Methodology: The paper combines both primary and secondary data, with a specific focus on two brands as case studies: Lush and Kiehl's. Primary data was collected through a questionnaire that includes bo

BACKGROUND: The beneficial effects of hormonal therapy in stimulating spermatogenesis in patients with non-obstructive azoospermia (NOA) and either normal gonadotrophins or hypergonadotropic hypogonadism prior to surgical sperm retrieval (SSR) is controversial. Although the European Association of Urology guidelines state that hormone stimulation is not recommended in routine clinical practice, a

The Eurasian spruce bark beetle, Ips typographus, is a major pest, capable of killing spruce forests during large population outbreaks. Recorded dispersal distances of individual beetles are typically within hundreds of meters or a few kilometers. However, the connectivity between populations at larger distances and longer time spans and how this is affected by the habitat is less studied, despite
