Aviation is a substantial and a fast growing emissions source. Besides greenhouse gases, aircraft engines emit black carbon (BC), a climate forcer and air pollutant. Aviation BC emissions have been regulated and estimated through exhaust smoke visibility (smoke number). Their impacts are poorly understood because emission inventories lack representative data. Here, we measured BC mass and number-based emissions of the most popular airliner's engines according to a new emission standard. We used a calibrated engine performance model to determine the emissions on the ground, at cruise altitude, and over entire flight missions...

Exposure to the microgravity conditions of spaceflight alleviates the load normally imposed by the Earth's gravitational field upon the inner ear utricular epithelia. Previous ultrastructural investigations showed that spaceflight induced an increase in synapse density within hair cells of the rat utricle. However, the utricle exhibits broad physiologic heterogeneity across different epithelial regions, and it is unknown whether capabilities for synaptic plasticity generalize to hair cells across its topography...

Sten-Ove Andersson, Lars Lundberg, Anders Jonsson, Pia Tingström, Madeleine Abrandt Dahlgren
The aim of this study was to identify physicians' and nurses' perceptions of military pre-hospital emergency care before and after an international mission. A qualitative empirical study with a phenomenographic approach was used. The results after pre-deployment training can be categorised as (1) learning about military medicine and (2) taking care of the casualty. The results after an international mission can be categorised as (1) collaborating with others, (2) providing general health care and (3) improving competence in military medicine...

We report a systematic spectroscopical investigation of three plagioclase particles (RB-QD04-0022, RA-QD02-0025-01, and RA-QD02-0025-02) returned by the Hayabusa spacecraft from the asteroid Itokawa, by means of scanning electron microscopy, cathodoluminescence microscopy/spectroscopy, and micro-Raman spectroscopy. The cathodoluminescence properties are used to evaluate the crystallization effects and the degree of space weathering processes, especially the shock-wave history of Itokawa. They provide new insights regarding spectral changes of asteroidal bodies due to space weathering processes...

In this work stress is assessed based on EEG features. We focus our efforts on the correlation between subjective ratings and cerebral indices during virtual navigation scenarios. Ten male paraplegic subjects took part in the experiment and navigated in a virtual indoor environment. They had to fulfill two missions where time pressure parameter is introduced. Subjects were equipped with Electroencephalography sensors. Temporal and frequency data were filtered and extracted. A correlation study was conducted based on principal component analysis, Fisher's tests and ANOVA...

The telemedical support and networking between health personnel and medical specialists increases the quality of supply also in the prehospital emergency care. Till now only for some tracer diagnosis specifically designed telemedical services were used. However, now a unique holistic telemedicine system, which can be used for the whole emergency spectrum as a supplementary feature has been developed. It can be used for the whole prehospital emergency care. The needfulness and meaningfulness of telemedicine as well as the important structural characteristics in prehospital emergency care are pictured...

In this editorial, the new incoming editor for the Journal of Personality and Social Psychology (JPSP)addresses the upcoming challenges and the issue of replicability. Although people vary (often dramatically) in their views on the nature and extent of this issue, that we have an issue to address is something that the new editor thinks most scholars would agree on. It is her hope that engaging in these efforts will return our community to a place that young talent willingly and safely bets their futures on...

Among the dangers to astronauts engaging in deep space missions such as a Mars expedition is exposure to radiations that put them at risk for severe cognitive dysfunction. These radiation-induced cognitive impairments are accompanied by functional and structural changes including oxidative stress, neuroinflammation, and degradation of neuronal architecture. The molecular mechanisms that dictate CNS function are multifaceted and it is unclear how irradiation induces persistent alterations in the brain. Among those determinants of cognitive function are neuroepigenetic mechanisms that translate radiation responses into altered gene expression and cellular phenotype...

Health risks from space radiations, particularly from densely ionizing radiations, represent an important challenge for long-ranged manned space missions. Reliable methods are needed for scaling low-LET to high-LET radiation risks for humans, based on animal or in vitro studies comparing these radiations. The current standard metric, relative biological effectiveness (RBE) compares iso-effect doses of two radiations. By contrast, a proposed new metric, radiation effects ratio (RER), compares effects of two radiations at the same dose...

Blood vessels have a unified mission to circulate blood throughout the body; however, they have additional diverse and specialized roles in various organs. For example, in the liver, discontinuous sinusoids, which are fenestrated capillaries with intercellular gaps and a fragmented basement membrane, facilitate delivery of macromolecules to highly metabolic hepatocytes. During embryonic development, discontinuous sinusoids also allow circulating hematopoietic progenitor and stem cells to populate the liver and promote blood cell differentiation...

Occupational therapy is a field with a long-standing history of recommending and implementing interventions designed to improve the quality of life of clients with disabilities. Often, the interventions are individualized to meet the needs of this diverse group of clients in dynamic settings. Identifying effective and efficient interventions for such a diverse group of clients and settings requires a flexible research approach. Single-case experimental designs (SCEDs) allow practitioners and researchers to answer experimental questions within the context of rigorous research designs...

BACKGROUND: Short-term medical missions (STMMs) are quite common and largely understood to be a response to health needs in low-income countries. Yet most information about STMM practices is anecdotal. Even less is known about the preferences of in-country host communities regarding STMMs. OBJECTIVE: We aimed to gather enough quantitative and qualitative information from both STMM organizers and host community staff to compare dominant practices of organizers as well as preferences of host community staff...
