    This report presents the latest data from ongoing excavations at Jebel Moya, Sudan. This year saw the opening of five new trenches and continued excavation of an archaeologically rich trench. We have recovered four individual burials, a mud brick wall and a number of animal and archaeobotanical remains. The excavations also yielded a longer pottery sequence, showing clearly that the site was in use by at least the sixth millennium BC. This season confirms the long and complex history of Jebel Moya and provides the material for future studies on population health and subsistence. This season also saw an increase in community engagement and a more detailed study of the various historical trajectories that make up the biography of Jebel Moya

    Near-threshold boson pair production in the model of smeared-mass unstable particles

    Full text link
    Near-threshold production of boson pairs is considered within the framework of the model of unstable particles with smeared mass. We describe the principal aspects of the model and consider the strategy of calculations including the radiative corrections. The results of calculations are in good agreement with LEP II data and Monte-Carlo simulations. Suggested approach significantly simplifies calculations with respect to the standard perturbative one.Comment: 15 pages, 6 figures, minor corrections, references adde

    Background: - Healthcare professions have rapidly developed due to advancements in technology along with innovations over years, and Physiotherapists are considered as a key-member of collaborative inter-professional teams due to their broad scope of practice. - Increasing disabilities in Palestine due to occupation and other reasons, life expectancy and the special circumstances made it one of the most imperative socioeconomic medical issues in Gaza Strip. This emphasizes the need for the development and recognition of physiotherapy in multidisciplinary healthcare structures. - In order to deliver effective care, communication, cooperation and agreement between physicians and physiotherapist is essential. - If a physician were well informed about physiotherapy abilities in helping the treatments, prevent complications and decrease hospital stays, that would decrease the burden on the healthcare system. - Lack of knowledge about physiotherapy among medical professionals affects several aspects, including patients, the role of physiotherapy as a part of the healthcare teams, and the outcomes. Objectives: - The aim of the study was to identify awareness, perception and believes about physiotherapy among orthopedists and neurosurgeons. Methods: - A cross-sectional study was conducted between January – June 2019 at the three main hospitals of the Ministry of Health in Gaza Strip. The study population included Orthopedists and Neurosurgeons who work according to the settings. - The total collected samples were 67, and participants of the study were recruited through a Non-Probability convenience sample. - Data was collected through a questionnaire, that was designed in English, with four main parts, a total of 30 items, then data analysis using the (SPSS-V.22) and several statistical operations were done including Cross tabulation using chi-squarer with significance value was defined as p≀0.05. Results: - Results of this study showed that the awareness of orthopedists and neurosurgeons about physiotherapy was 95.5%. The study showed that 54.7% of these physicians received their knowledge through their studying. The study showed that 78.1% of physicians believe that the intervention of physiotherapy is in therapeutic exercises, while 57.8% believe that the biggest intervention is the use of electrical modalities, and 60.9% believe that it is manual therapy. The study found that 96.9% of physicians believe that physiotherapy plays an important role in the treatment plan for the patient. And 71.9% of the physicians believe that the physiotherapist has the right to return the patient to the physician due to misdiagnosis. The study indicated that 90.6% of physicians believe it is important to discuss the patient's discharge with a physiotherapist, and shocking result was that 95.3% of physicians say that they write on the referral what should a physiotherapist do to a patient, and that is a huge violation of the physiotherapists right of making their own decision. Conclusions: - There is a close association between orthopedists and neurosurgeons about physiotherapy. The study has shown that they have a clear awareness, perception and beliefs about physiotherapy. - This relationship should be supported and developed to provide the best possible treatment to patients

    The ATLAS Collaboration has measured the inclusive production of Z bosons via their decays into electron and muon pairs in p+Pb collisions at √ sNN = 5.02 TeV at the Large Hadron Collider. The measurements are made using data corresponding to integrated luminosities of 29.4 nb−1 and 28.1 nb−1 for Z → ee and Z → ””, respectively. The results from the two channels are consistent and combined to obtain a cross section times the Z → `` branching ratio, integrated over the rapidity region |y ∗ Z | < 3.5, of 139.8 ± 4.8 (stat.) ± 6.2 (syst.) ± 3.8 (lumi.) nb. Differential cross sections are presented as functions of the Z boson rapidity and transverse momentum, and compared with models based on parton distributions both with and without nuclear corrections. The centrality dependence of Z boson production in p+Pb collisions is measured and analyzed within the framework of a standard Glauber model and the model’s extension for fluctuations of the underlying nucleon-nucleon scattering cross sectionFil: Aad, G..

    A measurement of the parity-violating decay asymmetry parameter, αb, and the helicity amplitudes for the decay Λb0→J/ψ(ÎŒ+ÎŒ-)Λ0(pπ-) is reported. The analysis is based on 1400 Λb0 and Λ¯b0 baryons selected in 4.6  fb-1 of proton-proton collision data with a center-of-mass energy of 7 TeV recorded by the ATLAS experiment at the LHC. By combining the Λb0 and Λ¯b0 samples under the assumption of CP conservation, the value of αb is measured to be 0.30±0.16(stat)±0.06(syst). This measurement provides a test of theoretical models based on perturbative QCD or heavy-quark effective theory.Fil: F. Monticelli.Fil: Atlas Collaboration

    Inhibition effect of Vernonia amygdalina (bitter leaf) extract on the corrosion behaviour of embedded mild steel rebar in concrete immersed in 0.2% H2SO4 solution was investigated by potential measurement, pH and gravimetric methods using the extracts concentrations of 25, 50, 75, and 100%. The results were further analysed using the two-factor ANOVA test. Potential measurement was performed using a digital voltmeter and a copper/copper sulphate reference electrode. Compressive strength of each block sample was determined after the experiments. Weight loss values were obtained from the gravimetric method, and the inhibitor efficiency was computed from the corrosion rate of each of the tested samples. Results showed that varied concentration of V. amygdalina and the test exposure time significantly affect both the corrosion potential of embedded steel rebar in concrete and the pH of the medium. The extracts gave appreciable corrosion inhibition performance of the embedded steel rebar at 25 and 50% concentrations with the weight loss of 500 (0.5 g) and 400 mg (0.4 g) and corrosion rates values of 0.000240 and 0.000180 mm/ yr, respectively. The highest inhibition efficiency (60.68%) was achieved at 50 and 39.94% at 25% concentrations, respectively. The 100 and 75% concentrations gave negative inhibitor values of ïżœ51.52 and ïżœ20.11%. The ANOVA test confirmed the results at 95% confidence, and further showed that concentration of V. amygdalina had greater effect on potential and pH measurement

    Managing toxicities associated with immune checkpoint inhibitors: consensus recommendations from the Society for Immunotherapy of Cancer (SITC) Toxicity Management Working Group.

    Get PDF
    Cancer immunotherapy has transformed the treatment of cancer. However, increasing use of immune-based therapies, including the widely used class of agents known as immune checkpoint inhibitors, has exposed a discrete group of immune-related adverse events (irAEs). Many of these are driven by the same immunologic mechanisms responsible for the drugs\u27 therapeutic effects, namely blockade of inhibitory mechanisms that suppress the immune system and protect body tissues from an unconstrained acute or chronic immune response. Skin, gut, endocrine, lung and musculoskeletal irAEs are relatively common, whereas cardiovascular, hematologic, renal, neurologic and ophthalmologic irAEs occur much less frequently. The majority of irAEs are mild to moderate in severity; however, serious and occasionally life-threatening irAEs are reported in the literature, and treatment-related deaths occur in up to 2% of patients, varying by ICI. Immunotherapy-related irAEs typically have a delayed onset and prolonged duration compared to adverse events from chemotherapy, and effective management depends on early recognition and prompt intervention with immune suppression and/or immunomodulatory strategies. There is an urgent need for multidisciplinary guidance reflecting broad-based perspectives on how to recognize, report and manage organ-specific toxicities until evidence-based data are available to inform clinical decision-making. The Society for Immunotherapy of Cancer (SITC) established a multidisciplinary Toxicity Management Working Group, which met for a full-day workshop to develop recommendations to standardize management of irAEs. Here we present their consensus recommendations on managing toxicities associated with immune checkpoint inhibitor therapy

    Exotic dense-matter states pumped by a relativistic laser plasma in the radiation-dominated regime

    Get PDF
    In high-spectral resolution experiments with the petawatt Vulcan laser, strong x-ray radiation of KK hollow atoms (atoms without n = 1 electrons) from thin Al foils was observed at pulse intensities of 3 x 10(20) W/cm(2). The observations of spectra from these exotic states of matter are supported by detailed kinetics calculations, and are consistent with a picture in which an intense polychromatic x-ray field, formed from Thomson scattering and bremsstrahlung in the electrostatic fields at the target surface, drives the KK hollow atom production. We estimate that this x-ray field has an intensity of >5 x 10(18) W/cm(2) and is in the 3 keV range
