Hydrated electrons are important in radiation chemistry and charge-transfer reactions, with applications that include chemical damage of DNA, catalysis, and signaling. Conventionally, hydrated electrons are produced by pulsed radiolysis, sonolysis, two-ultraviolet-photon laser excitation of liquid water, or photodetachment of suitable electron donors. Here we report a method for the generation of

A major focus of research in the seismic industry of the past two decades has been the acquisition and subsequent separation of seismic data using multiple sources fired simultaneously. The recently introduced method of signal apparition provides a new take on the problem by replacing the random time-shifts usually employed to encode the different sources by fully deterministic periodic time-shift

Fler arter än någonsin i mänsklighetens historia hotas av utrotning och den biologiska mångfalden lokalt har förändrats kraftigt i en stor del av världens ekosystem. Grundläggande förändringar behövs både i samhället och för individer, för att bromsa den negativa trenden, skriver en rad debattörer.

Late Permian mass extinction (LPME) research has focused primarily on Tethyan sections because it is believed that these successions are more complete than those from other localities, and provide a more comprehensive record of the largest, most devastating extinction event in Earth history. The Kisejin section, a previously undocumented mid-Tethyan, Upper Permian-Lower Triassic succession located

Context: Both scientific publications and grey literature have widely been employed as sources of empirical evidence in evidence-based software engineering (EBSE). However, there is still a fierce debate about whether or not the pervasive Web content can act as an alternative means to gather evidence for EBSE. Aim: To help ourselves enter this debate, this work aims to obtain some pre-evidence of

Assessment of breast density at the point of mammographic examination could lead to optimized breast cancer screening pathways. The onsite breast density information may offer guidance when to recommend supplemental imaging for women in a screening program. In this work, performance evaluation of a new software (Insight BD, Siemens Healthcare GmbH) for fast onsite quantification of volumetric brea

Aim: This study compared follow-up protocols for paediatric celiac disease (CD) led by either paediatricians or dietitians at Swedish university hospitals. Methods: We followed 363 CD patients under 18 years at the university hospitals in Malmö (n = 140) and Lund (n = 79) between 2011 and 2013 and after they merged to become Skåne (n = 144) between 2014 and 2016. Both Lund and Malmö provided regul

Bone tissue is commonly transplanted during orthopedic surgeries, primarily for the management of bone defects caused by trauma or various orthopedic conditions including, but not limited to, infections and tumours. Bone grafts are a surgeon’s choice, but their associated drawbacks are paving the way for biomaterial based bone graft substitutes. Biomaterials inherently lack the ability to induce s

AbstractAnkylosing spondylitis (AS) and undifferentiated spondyloarthritis (USpA) are two subgroups of the rheumatic disease spondyloarthritis (SpA). The diseases typically debut in early adulthood with periods of fluctuating and persistent pain and stiffness, and can result in consequences such as impaired functioning and reduced quality of life. SpA is a heterogenous group but AS and USpA share

The chapter analyses the outcomes of recent economic agreements and unions that have affected the interests and attitudes of multiple actors in the Trans-European space. The author explores the effects of these unions on trade flows and investment, both in the EU and in ten countries of the EU neighborhood. The chapter contributes to the book's narrative by examining spill-over effects of financia

Chronic suppurative otitis media often ensues in patients treated with irradiation against a head and neck tumor. In an experimental study, rats were exposed to irradiation to evaluate the sensitivity of the middle ear to an accumulated irradiation dose of 20-45 Gy. Observed otomicroscopically, all animals appeared to have normal tympanic membranes and no fluid developed in the middle ear space. T

The particle longitudinal dynamics is affected by errors on the phase and amplitude of the electro-magnetic field in each cavity that cause emittance growth, beam degradation and losses. One of the causes of the phase error is the change of the ambience temperature in the LINAC tunnel, in the stub and in the klystron gallery that induces a phase drift of the signal travelling through the cables an

Royal tombs and monuments, such as the imperial tombs of India and the Escorial of Spain, are among the best-known monuments of the early modern period. This article compares the Escorial, which served as the dynastic vault for the Spanish Habsburgs but particularly glorified Emperor Charles V, and the tomb built for the Mughal emperor Humayun. Both were built by their sons, Philip II (r. 1556-159
