Magnesium (Mg) is a metallic material with a great range of potential applications. It can be used as the lightest structure material in automotive and aviation sectors, medical implants, hydrogen storge, etc. In such applications, oxidation and corrosion reactions play a critical role in the effectiveness of use. Therefore, deeper understanding of the fundamental mechanisms of oxidation and corro
This manuscript reports the results of an international consensus on technologies of hyperthermic intraperitoneal perioperative chemotherapy (HIPEC) performed with the following goals: To provide recommendations for the technological parameters to perform HIPEC. To identify the role of heat and its application forms in treating peritoneal metastases. To provide recommendations regarding the correc
In addition to the family context, persons in the neighborhood and community are important for individual life course, socioeconomic and demographic outcomes such as education, career and family transitions. This paper aims to study how neighborhood conditions in childhood influence fertility outcomes in adulthood. Theories focusing on motivation, aspirations and attitudes or peer influence genera
This study explored the international research collaboration led by China’s world-class universities and its impact during the first construction cycle of the “Double First-Class” initiative (2016–2020). We collected international collaborative publications based on the Scopus database and examined the performance of international research collaboration in terms of quantity, impact, collaborative
Purpose: To assess how general practitioners (GPs) from European countries prioritized their genetic educational needs according to their geographic, sociodemographic, and educational characteristics. Methods: Cross-sectional survey, random and total samples of GPs in five European countries (France, Germany, the Netherlands, Sweden, and United Kingdom), mailed questionnaires; Outcome: Genetic Edu
The present series comprises all families (n = 77) with haemophilia B in Sweden and may be considered to be representative for the purposes of a population-based study of mutational heterogeneity. The 77 families (38 severe, 10 moderate, 29 mild) had 51 different mutations in total. Thirteen families had total, partial or small deletions, two had mutations in the promoter, eight families had splic
Objectives: To compare a laparoscopic (totally extraperitoneal patch (TEP)) and an open technique (Lichtenstein) for inguinal hernia repair regarding recurrence rate and possible risk factors for recurrence. Summary Background Data: Laparoscopic hernia repair has been introduced as an alternative to open repair. Short-term follow-tip suggests benefits for those patients operated with a laparoscopi
OBJECTIVE: To investigate differences in semen quality between samples collected by masturbation at a clinic and at home. DESIGN: Cross-sectional study. SETTING: Fertility center. PATIENT(S): Three hundred seventy-nine men assessed for infertility. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Semen was analyzed according to World Health Organization guidelines. Seminal markers of epididymal (ne
Hepatitis B virus (HBV) infection is one of most common viral infections worldwide. While chronic HBV infection has been shown consistently to be associated with hepatocellular carcinoma, data on associations with cancers at other sites are limited. In this study a total of 10,197 patients were diagnosed with chronic HBV infection in Sweden, and they were retrieved from the nationwide Swedish Hosp
Time-series of digital elevation models (DEMs) of the forefield of the Bruarjokull surge-type glacier in Iceland were used to quantify the volume of material that was mobilized by the 1963-1964 surge. The DEMs were produced by stereophotogrammetry on aerial photographs from before the surge (1961) and after (1988 and 2003). The analysis was performed on two DEMs of Difference (DoDs), i.e., a 1961-
Anomalous small angle scattering measurements have been applied to diluted solutions of anionic polyacrylates decorated by specifically-interacting Pb2+ cations, revealing partial collapse of the polyacrylate into pearl-like subdomains with a size on the order of a few nanometers. From the pure-resonant scattering contribution of the Pb2+ cations, and from subsequent analysis of the resonant-invar
Raw municipal wastewater from a full-scale wastewater treatment plant was physicochemically pretreated in a large pilot-scale system comprising coagulation, flocculation, microsieve and microfiltration operated in various configurations. The produced microsieve filtrates and microfiltration permeates were then concentrated using forward osmosis (FO). Aquaporin InsideTM FO membranes were used for b
The diatom Chaetoceros calcitrans is a major component of many bivalve hatcheries, yet it is expensive and notoriously difficult to culture on a commercial scale. In an attempt to reduce dependence on the diatom C. calcitrans, mussel larvae (Mytilus galloprovincialis) were subjected to feeding experiments which altered levels of the diatom under controlled hatchery conditions. Growth, survival and
Objective: To define the role of ultrasound (US) for the assessment of patients with rheumatoid arthritis (RA) in clinical remission, including joint and tendon evaluation. Methods: A multicentre longitudinal study has been promoted by the US Study Group of the Italian Society for Rheumatology. 25 Italian centres participated, enrolling consecutive patients with RA in clinical remission. All patie
Objectives: COPD is a common and disabling disease that entails high costs for society. The objectives of this study were to measure the societal costs of COPD in Sweden, and to examine the relationship between severity of illness and costs. Methods: The costs of COPD were examined using a well-defined and representative cohort of subjects with mild, moderate, and severe COPD. Regular telephone in
Massive multiple-input multiple-output (MIMO) is expected to be a vital component in future 5G systems. As such, there is a need for new modeling in order to investigate the performance of massive MIMO not only at the physical layer but also higher up the networking stack. In this paper, we present general optimization models for massive MIMO, based on mixed-integer programming and compatible sets
