#1
Thomas Kick, Thomas Grethe, Boris Mahltig
A treatment for hydrophobic functionalization of natural fiber materials is developed. This hydrophobic treatment is based mainly on natural products. As hydrophobic component the natural Tung Oil is used, which is originally a compound used for wood conservation purposes. The application on textile is done in a padding process under presence of an oxidative agent. For the current investigations a fiber felt from linen was used. The hydrophobic effect is determined by the concentration of Tung Oil and the duration of a thermal drying process...

Liam R Dougherty, Leigh W Simmons
In the seed beetle Callosobruchus maculatus, the male intromittent organ is covered in sharp spines that pierce the female copulatory tract wall during mating. Although the fitness consequences of traumatic mating are well studied in this species, we know much less about how the male and female genitalia interact during mating. This is partly due to the fact that genital interactions occur primarily inside the female, and so are difficult to observe. In this study, we use X-ray micro-CT scanning to examine the proximate mechanisms of traumatic mating in C...

G Di Vella, I Grattagliano, M C Romanelli, J B Duval, R Catanesi
Parricide is a category of homicide in which the victims are the parents, and the killers, their children. The authors report a case of a 45-year-old man who killed his 73-year-old widowed father in an extremely violent manner: he struck the father in the head with a wooden wash board, stabbed him with a pair of scissors and several times with a screwdriver. Afterwards, he kicked the victim in the face and jumped up and down on his body, thereby crushing the father's chest with his weight. The case reported here may be classified as an "unusual patricide" when one considers the age of the aggressor, the diagnosis of psychiatric disorders, that the victim was the father, and that the murder was committed in an extremely violent manner...

There is growing evidence indicating positive, causal effects of acute physical activity on cognitive performance of school children, adolescents, and adults. However, only a few studies examined these effects in kindergartners, even though correlational studies suggest moderate relationships between motor and cognitive functions in this age group. One aim of the present study was to examine the correlational relationships between motor and executive functions among 5- to 6-year-olds. Another aim was to test whether an acute coordinative intervention, which was adapted to the individual motor functions of the children, causally affected different executive functions (i...

In this study, we investigated the effects of increased kick frequency on the propelling efficiency and the muscular co-activation during underwater dolphin kick. Participants included eight female collegiate swimmers. The participants performed seven 15-m underwater dolphin kick swimming trials at different kick frequencies, which is 85, 90, 95, 100, 105, 110, and 115% of their maximum effort. The Froude (propelling) efficiency of the dolphin kick was calculated from the kinematic analysis. The surface electromyography was measured from six muscles (rectus abdominis, erector spinae, rectus femoris, biceps femoris, tibialis anterior, and gastrocnemius)...

Diversity is a fundamental, yet threatened, property of ecological systems. The idea that diversity can itself favour diversification, in an autocatalytic process, is very appealing but remains controversial. Here, we study a generalized model of ecological communities and investigate how the level of initial diversity influences the possibility of evolutionary diversification. We show that even simple models of intra- and inter-specific ecological interactions can predict a positive effect of diversity on diversification: adaptive radiations may require a threshold number of species before kicking-off...

Tobacco consumption is a significant national public health issue. The waste it generates-tobacco product waste (TPW)-is also an environmental hazard. Targeting TPW through novel policies/regulations-such as a cigarette butt deposit scheme-may serve the dual purposes of reducing an environment nuisance and progressing Aotearoa New Zealand to its goal of being smokefree by 2025.

Blood oxygenation mapping by the means of optical oximetry is of significant importance in clinical trials. This paper uses hyperspectral imaging technology to obtain in vivo images for blood oxygenation detection. The experiment involves dorsal skin fold window chamber preparation which was built on adult (8-10 weeks of age) female BALB/c nu/nu mice and in vivo image acquisition which was performed by hyperspectral imaging system. To get the accurate spatial and spectral information of targets, an automatic registration scheme is proposed...

A 2-year-old girl presented to the emergency department with a 3-day history of a painful stiff neck after getting a kick to her head from her older brother. Her general practitioner had recently started her on oral antibiotics for otitis media. Plain film imaging of her cervical spine on admission revealed anterior subluxation of C2 on C3 suggestive of bifacetal dislocation. Subsequent CT imaging confirmed malalignment of the upper cervical spine. The patient was admitted and worked up with MRI of the cervical spine which unexpectedly revealed a large 4×2 cm retropharyngeal abscess extending from C1 to C4...

Through first-principles calculations and crystal structure prediction techniques, we identify a new layered oxysulfide LiAlSO in orthorhombic structure as a novel lithium superionic conductor. Two kinds of stacking sequences of layers of AlS_{2}O_{2} are found in different temperature ranges. Phonon and molecular dynamics simulations verify their dynamic stabilities, and wide band gaps up to 5.6 eV are found by electronic structure calculations. The lithium migration energy barrier simulations reveal the collective interstitial-host ion "kick-off" hopping mode with barriers lower than 50 meV as the dominating conduction mechanism for LiAlSO, indicating it to be a promising solid-state electrolyte in lithium secondary batteries with fast ionic conductivity and a wide electrochemical window...

CASE REPORT: A 35-year-old man suffered a severe hipotension maculopathy after being kicked in his left eye. He presented a broad area of iridodialisis. Gonioscopy, ultrasound biomicroscopy and optic coherence tomography were not able to locate the suspected cyclodialysis. Medical treatment was ineffective. Five months later the patient received transcleral diode laser cyclophotocoagulation with clinical resolution. DISCUSSION: Transscleral diode laser constitutes an effective treatment, with low iatrogenia, that can solve cases of ocular hypotension, even when the location of the cyclodialysis has not been determined...

We report on the observation of the coherent enhancement of the return probability ["enhanced return to the origin" (ERO)] in a periodically kicked cold-atom gas. By submitting an atomic wave packet to a pulsed, periodically shifted, laser standing wave, we induce an oscillation of ERO in time that is explained in terms of a periodic, reversible dephasing in the weak-localization interference sequences responsible for ERO. Monitoring the temporal decay of ERO, we exploit its quantum-coherent nature to quantify the decoherence rate of the atomic system...

REVIEW
Pedro H Papotto, Julie C Ribot, Bruno Silva-Santos
Shortly after the discovery of interleukin 17 (IL-17)-producing CD4(+) helper T cells (TH17 cells), it was found that γδ T cells can also secrete large amounts of this pro-inflammatory cytokine. A decade later, it is now known that IL-17(+) γδ T cells (γδ17 T cells) are often the main providers of IL-17A in various models of inflammatory diseases, while they also contribute to protective immune responses to infectious organisms. Due to an intricate thymic program of differentiation, γδ17 T cells are able to respond faster than TH17 cells do and thus predominate in the early stages of inflammatory responses...
