- The introduction of Vehicular ad-hoc Networks (VANETs) leads to the possibility to re-evaluate many traditional functions and views of road traffic networks. The ability for vehicles and infrastructure to commu- nicate and collaborate will enable many novel solutions for problems as diverse as collision avoidance and traffic management with the view of re- ducing traffic congestion, increasing the effectiveness of logistics systems etc. In this paper we introduce a novel framework that utilises VANET in- formation to share information about risk factors among road occupants and infrastructure. We introduce the concept of risk limits as a means of traffic accident risk mitigation, whereby vehicles need to adjust their be- haviour to maintain a given level of risk. We discuss determination of risk values and detail this process using the NSW traffic accident database. We show how the effects on risk of particular vehicular behaviours such as speed and headway can be calculated and use these results to modify vehicle behaviour in real time to maintain a predefined risk limit. Exper- iments are carried out using the Paramics microsimulator. Our results show that it is possible to reduce the accident rate among vehicles while at the same time increasing road network throughput by exploiting the variation in risk between vehicles.

- Graphene oxide membranes were recently suggested for applications in separation of ethanol from water using a vapor permeation method. Using isotope contrast, neutron reflectivity was applied to evaluate the amounts of solvents intercalated into a membrane from pure and binary vapors and to evaluate the selectivity of the membrane permeation. Particularly, the effect of D2O, ethanol and D2O–ethanol vapours on graphene oxide (GO) thin films (25 nm) was studied. The interlayer spacing of GO and the amount of intercalated solvents were evaluated simultaneously as a function of vapour exposure duration. The significant difference in neutron scattering length density between D2O and ethanol allows distinguishing insertion of each component of the binary mixture into the GO structure. The amount of intercalated solvent at saturation corresponds to 1.4 molecules per formula unit for pure D2O (1.4 monolayers) and 0.45 molecules per formula unit (one monolayer) for pure ethanol. This amount is in addition to H2O absorbed at ambient humidity. Exposure of the GO film to ethanol–D2O vapours results in intercalation of GO with both solvents even for high ethanol concentration. A mixed D2O–ethanol layer inserted into the GO structure is water enriched compared to the composition of vapours due to slower ethanol diffusion into GO interlayers

- The aim of this research is to individuate a design product or service application to create a territorial specificity, using the reference of a colour palette with historical and geographical values, picked out in the spirit of Linnaeus, the Swedish botanist,and characteristic of the Öland island, in Sweden. It equally wants to highlight the design process as a possible methodology for product and service developmentenhancing territorial value.

- Photoplethysmogram (PPG) signals obtained from wearable sensors have been utilized for monitoring health conditions in both clinical and non-clinical environments, mostly concerning with heart-rate events. This paper shows the potential use of short-time PPG signals for differentiating patients with Parkinsons disease (PD) from healthy control (HC) subjects with nonlinear dynamics analysis. Multiscale entropy, time-shift multiscale entropy, and fuzzy recurrence plots were applied for extracting features from PPG signals of PD patients and HC subjects. Least-square support vector machine based cross-validations of the features extracted from the three nonlinear dynamics analysis methods achieve high classification rates, where those obtained from fuzzy recurrence plots are the highest.

- Information from elemental and mass composition of size-fractionated airborne particle matter (PM) provides insightfulknowledge about their impact on human health, meteorology and climate. To attain insight into the nature of sizefractionatedPM from a typical African city, samples were collected from an urban background site in Nairobi, Kenya,during the months of August and September in 2007. PM samples ranging in size from 0.06 to 16 µm aerodynamicdiameter were collected on pre-weighed polycarbonate filters with 0.4 µm pore size using a nine-stage cascade impactor.Particles less than 0.06 µm were collected on a backup filter. A total of 170 samples were collected and analysed for traceelements using the Proton Induced X-Ray Emission (PIXE) technique. The analysis showed that Si, Fe and S dominated inall size ranges and displayed unimodal mass-size distribution whereas K, Cu, Zn and Pb, depicted bimodal mass-sizedistribution highlighting the multiplicity of their sources. To estimate human exposure to PM, deposition fractions of boththe coarse and fine PM in the human respiratory system were calculated. The deposited concentration was found to behighest in the head airways region compared to the tracheobronchial and pulmonary regions.

- The aim of this study was to evaluate, in women with preterm prelabor rupture of membranes (PPROM), the impact on short-term neonatal outcome of microbial invasion of the amniotic cavity (MIAC), intra-amniotic inflammation (IAI), and the microorganisms isolated in women with MIAC, when gestational age is taken into account.Prospective cohort study. We included women with PPROM (22.0-34.0 weeks of gestation) with available information about MIAC, IAI and short-term neonatal outcome. MIAC was defined as positive aerobic/anaerobic/genital Mycoplasma culture in amniotic fluid. Definition of IAI was based on interleukin-6 levels in amniotic fluid. Main outcome measures were Apgar score <7 at 5 min, umbilical artery pH ≤7.0, days in the neonatal intensive care unit, and composite neonatal morbidity, including any of the following: intraventricular hemorrhage grade III-IV, respiratory distress syndrome, early-onset neonatal sepsis, periventricular leukomalacia, necrotizing enterocolitis, and fetal or neonatal death. Labor was induced after 32.0 weeks if lung maturity was confirmed; and otherwise after 34.0 weeks.MIAC and IAI were found in 38% (72/190) and 67% (111/165), respectively. After adjustment for gestational age at delivery, no differences in short-term neonatal outcome were found between women with either MIAC or IAI, compared with the non-infection/non-inflammation ("No-MIAC/No-IAI") group. Furthermore, short-term neonatal outcome did not differ between the MIAC caused by Ureaplasma spp. group, the MIAC caused by other microorganisms group and the "No-MIAC/No-IAI" group.Gestational age at delivery seems to be more important for short-term neonatal outcome than MIAC or IAI in PPROM.
