    Opis:
    The nonlinear response of rock is much different than that of ordinary materials. Especially at ambient conditions, rock responds in an extremely nonlinear fashion, often due to the presence of hysteresis. Nonlinear elastic response in rock is illustrated by dynamic results from resonant bar and pulse-mode experiments.

    Opis:
    The Canadian health care system is a publicly financed system administered by ten provincial and three territorial governments. The purpose of this article is to provide an overview of the universal health care system in Canada, including its history, the health status of Canadians, health care funding and spending, and health research and data collection. Health care spending in Canada amounts to 11.6% of the country’s gross domestic product and is estimated to have been $200.5 billion Canadian dollars in 2011. Hospitals account for the largest source of health care spending (29%), followed by drugs (16%) and physician spending (14%). Of the total health care spending, 70% is paid for by the public system. Due to the Canadian population being covered by the universal health care system, health data are being collected and can be used to monitor the health care system and inform evidence-based medicine.

    Opis:
    The past few decades have witnessed a tremendous increase in the consumption of antibiotics worldwide. This rampant and unregulated use of antibiotics and their improper disposal has led to the accumulation of these drugs in the environment. This in turn has led to the emergence of antibiotic resistance in microbes and has become one of the most pressing global concerns in medicine, with highly resistant pathogens of many species proving difficult to treat. The aim of the study was to synthesise silver nanoparticles (Ag-NPs) using white rot fungus, Pleurotus ostreatus and assess its potential to carry out photocatalytic degradation of ampicillin. UV–Vis spectroscopy, Fourier transform infrared spectroscopy and transmission electron microscope have been used to characterize biosynthesized Ag-NPs. The photocatalytic degradation of ampicillin in aqueous solution by Ag-NPs was evaluated under natural sunlight. The effect of the operating conditions (contact time, Ag-NP concentration and initial ampicillin concentration) on the photocatalytic degradation was also investigated. The highest ampicillin degradation of 96.5% was observed after exposure of the solution (antibiotic + nanoparticles) for 4 h in sunlight. The maximum degradation was observed at an Ag-NP concentration of 5 ppm at pH 6. To the best of our knowledge, photocatalytic degradation of ampicillin using Ag-NPs synthesised by P. ostreatus has not been reported earlier.

    Opis:
    Ankle sprains are common soft-tissue injuries that are often treated in emergency departments. These injuries can have significant consequences for the patient, including long-term morbidity and loss of productivity. The objective of this study was to examine the direct and indirect health resource utilization associated with ankle sprains. 296 adult patients with acute ankle sprains participated in the study in Kingston, Ontario, Canada. Data were collected using a one-month productivity questionnaire. Overall, 11% (95% CI, 8-15%) of the participants visited a physician following the initial emergency department visit. Almost all (95%; 95% CI, 92-97%) of the participants used medications or supportive treatments and 55% (95% CI, 50-61%) reported taking time off from work, school, or housework. The use of unpaid assistance was indicated by 56% (95% CI, 50-62%). Findings from this analysis highlight the significant patient-related and health care system burden of acute ankle sprains.

    Opis:
    The Urak Lawoi are indigenous fishermen on Thailand’s west coast. The population includes an estimated 400 divers who dive using surface-supplied compressed air. In a cross-sectional survey conducted among the 6 major communities of Urak Lawoi, questionnaire-based interviews were administered to active divers, ex-divers, and families or colleagues of divers who had died in the previous 5 years. Six deaths resulting from diving-related accidents were identified, indicating a diving-related mortality rate of approximately 300 per 100,000 person-years, while in the same 5-year period 11 divers had been disabled owing to diving-related events, indicating a diving-related disabling event rate of approximately 550 per 100,000 person-years. Among 342 active divers interviewed, one third reported having suffered from decompression illness, although based on reported current symptoms over 50% were classified as suffering from recurring non-disabling decompression illness. Physical examination conducted on a subset of 98 active divers revealed the presence of spinal injury (clonus, raised muscle tone, and heightened reflexes) and of joint damage (pain in one or more joint, crepitus, or restricted movement) in 24 and 30% respectively. Improved primary prevention and medical treatment are needed to reduce mortality and morbidity among this population.

    Opis:
    The electronic band structure of Mn/ZnTe(110) (1×1) has been studied by angle-resolved photoelectron spectroscopy. The sets of spectra were acquired for the clean surface and after in situ deposition of 0.4 ML of Mn, in order to compare the band structures and to reveal changes brought about by the presence of Mn. The experimental band structure diagram of Mn/ZnTe along theΓ-K direction in the Brillouin zone has been derived from the experimental data. Indications of interaction between the Mn 3d states and sp$\text{}^{3}$ bands of the semiconductor are discussed.

    Opis:
    This paper reports the synthesis, crystal structure, surface morphology, optical and electrical properties of Mg-doped Sn₂S₃ thin films deposited by spray pyrolysis technique. All the films exhibit orthorhombic crystal structure with a (211) preferential orientation. Crystallite size calculations based on the Debye-Scherrer formula indicated that the Sn₂S₃ crystallite size increases with Mg content from 27.97 nm to 33.58 nm. Scanning electron microscopy images showed that all the films were very smooth composed of nanoneedle and nanoplate shaped grains. The band gap energy of the films exhibits a blue shift from 1.94 eV to 2.09 eV with increase in Mg concentration. Resistivity values of the undoped and Mg-doped Sn₂S₃ films were found to be in the order of 0.1 Ωcm. From the obtained results it is observed that the Sn₂S₃ film coated with 2 wt% Mg concentration exhibits better physical properties.

    Opis:
    Resonant photoemission spectroscopy, with application of synchrotron radiation, was used to study the valence band electronic structure of clean surface of (EuGd)Te layers. Fano-type resonant photoemission spectra corresponding to the Eu 4d-4f transition were measured to determine the contribution of 4f electrons of Eu$\text{}^{2+}$ and Eu$\text{}^{3+}$ ions to the valence band. The resonant and antiresonant photon energies of Eu$\text{}^{2+}$ ions were found as equal to 141 V and 132 eV, respectively and for Eu$\text{}^{3+}$ ions were found as equal to 146 eV and 132 eV, respectively. Contribution of Eu$\text{}^{2+}$4f electrons was found at the valence band edge while for Eu$\text{}^{3+}$ it was located in the region between 3.5 eV and 8.5 eV below the valence band edge.

    Opis:
    Understanding the initial steps during ultrafast molecular reactions involving large spin state changes is a vital goal in structural dynamics research. These involve knowledge of the geometric structure of the system. Ultrafast X-ray absorption spectroscopy with 50-100 picosecond time resolution establishes the geometric structure of the short-lived (τ = 0.6 ns) high spin state. Here we focus on time-resolved X-ray absorption studies with 160-200 fs temporal resolution to monitor the structural evolution in this spin-conversion process.
