The role of surface-guided radiation therapy for improving patient safety

Emerging data indicates SGRT could improve safety and quality by preventing errors in its capacity as an independent system in the treatment room. The aim of this work is to investigate the utility of SGRT in the context of safety and quality. Three incident learning systems (ILS) were reviewed to categorize and quantify errors that could have been prevented with SGRT: SAFRON (International Atomic

Communicative coworkership

Communicative coworkership is an area with great potential for both organizations and communicators. Communicative coworkership is also an area where there is a clear link between the core operation and the communication of the organization. It is fairly easy to demonstrate the value of communicative coworkership for an organisation, for example in terms of crisis aversion, innovation, listening,

Communicating Cybersecurity Vulnerability Information: A Producer-Acquirer Case Study

The increase in both the use of open-source software (OSS) and the number of new vulnerabilities reported in this software constitutes an increased threat to businesses, people, and our society. To mitigate this threat, vulnerability information must be efficiently handled in organizations. In addition, where e.g., IoT devices are integrated into systems, such information must be disseminated from

Maternal separation leads to regional hippocampal microglial activation and alters the behavior in the adolescence in a sex-specific manner

Early life adversities during childhood (such as maltreatment, abuse, neglect, or parental deprivation) may increase the vulnerability to cognitive disturbances and emotional disorders in both, adolescence and adulthood. Maternal separation (MS) is a widely used model to study stress-related changes in brain and behavior in rodents. In this study, we investigated the effect of MS (postnatal day 2–

The effect of electroconvulsive therapy on neuroinflammation, behavior and amyloid plaques in the 5xFAD mouse model of Alzheimer's disease

Microglial cells are affected in Alzheimer's disease (AD) and interact with amyloid-beta (Aβ) plaques. Apart from memory loss, depression is common in patients with AD. Electroconvulsive therapy (ECT) is an anti-depressive treatment that may stimulate microglia, induce neuroinflammation and alter the levels of soluble Aβ, but the effects of ECT on microglia and Aβ aggregation in AD are not known.

“Wake-up call for the white race" : How Stormfront framed the elections of Obama and Trump

We investigate how users on a prominent forum for white supremacists interpreted and framed two seminal events for the far-right in the U.S., the elections of Obama in 2008 and Trump in 2016. These cases precipitated dramatic shifts in the far-right alliance and conflict structure. We combine computational methods and qualitative analysis on a corpus of over ten million posts on Stormfront.org to We investigate how users on a prominent forum for white supremacists interpreted and framed two seminal events for the far-right in the U.S., the elections of Obama in 2008 and Trump in 2016.

Smoke gas analysis by Fourier transform infrared spectroscopy - summary of the SAFIR project results

The determination of toxic components from fire gases is difficult because the environment is hot, reactions are often temperature dependent, and a lot of soot may be produced. Due to the different properties of the gas components, a different time-consuming procedure for each species has traditionally been used. The use of FTIR (Fourier transform infrared) spectrometers as a continuous monitoring

Fire safety of TV set enclosure materials, a survey of European statistics

The composition of enclosure materials used in many TV sets sold on the European market has changed significantly since the early 1990s. To determine the potential impact of this change on TV fire safety, a review of European and US TV set fire statistics has been carried out. TV set fires can have internal electrical causes due to faults not apparent at the time of manufacture, simple wear and te

Fire emissions into the atmosphere

The amount of various pollutants per year emitted into the atmosphere from fires in Sweden is estimated. The pollutants considered in detail are CO2, CO, HCN, NOx, SO2, HCl, unburned hydrocarbons, and particulate matter. The emission of N2O, aromatic hydrocarbons, dioxins, and heavy metals, is discussed qualitatively. The estimate is based on the number of fires in buildings and vehicles in Sweden

Quasiclassical trajectory study of the C + NO reaction on a new potential energy surface

A new many-body expansion (MBE) fit of the A″ surface associated with the reaction of atomic carbon and NO is presented. Trajectory calculations, based on this surface, of the rate coefficients for the reactions C(3P) + NO(X2Π) k1 CN(X2∑+) + O(3P) and C(P) + NO(X2Π k2 CO(X1∑+) + N(2D) are compared to experimental results over a range of temperatures from room temperature to combustion temperatures

RRKM studies of product branching in the NH+NO reaction

We use RRKM theory to calculate rate constants and product branching fractions for NH+NO, comparing results for an ab initio surface and two recent empirical surfaces. In addition we compare trajectory and RRKM branching fractions based on the empirical surfaces, including an assessment of zero-point energy effects on branching. Our calculations show that the ab initio and empirical surfaces give

A theoretical investigation of the two lowest potential energy surfaces for the reaction C(3P)+NO (2Π)

The two lowest potential energy surfaces for C(3P)+NO(2Π) have been investigated. The stationary points were first located using CASSCF gradient calculations and the geometries reoptimized using complete active space second-order perturbation theory. Zero-point corrections have been included in the energetics. In addition to the three linear conformations CNO, NCO and CON, a previously unreported

Quantum chemical investigation of the ArCHI interaction potential. Steepness and asymmetry with implications for energy transfer

Self-consistent field ab initio calculations using a previously published, optimized basis set [J. Chem. Phys. 94 (1991) 6677] and second-order Møller-Plesset (MP2) perturbation theory are used in a study of the ArHCl intermolecular potential. The ab initio results are compared to the recently published H6(4, 3, 0) potential-energy surface [J. Phys. Chem. 96 (1992) 4237]. Good agreement is obtaine

The chlorinating species in turbulent flame combustion of methane with hydrogen chloride present

Combustion of methane with air in the presence of hydrogen chloride was studied in a turbulent jet-stirred burner. The reaction was monitored by in situ mass spectometry and the ratio of Cl2 2HCl intensities was measured as a function of equivalence ratio (Φ). For values of Φ = 1.25 - 0.5 (fuel rich to fuel lean flames) the ratio of Cl2 2HCl intensities was close to zero. For values of Φ < 0.5 the

Apparatus for studying premixed laminar flames using mass spectrometry and fiber-optic spectrometry

An integrated flat-flame/ microprobe sampling quadrupole mass spectrometer system, complemented by optical spectrometry based on optical fibers, is presented. The short microprobe sampling line (total 25 cm) is directly connected to an open ion source closely flanked by two nude cryopumps (900 l/s) yielding a background pressure of 10-9 Torr and a sampling pressure of about 10-5 Torr. Due to this
