Comparative analysis of Iron Age bronze archaeological objects from a Picenum necropolis of Centre Italy with Prompt Gamma Activation Analysis

An archaeological area from the 8th and 7th centuries B.C. has been recently discovered during a rescue excavation near Matelica site (Marche Region, Italy) in the period 1994-2005. Out of the treasures found in the graves, 18 bronze objects have been chosen for Prompt Gamma Activation Analysis (PGAA) at the Budapest Research Reactor (BRR), selected from the 7th century B.C. archaeological founds of Matelica and Fabriano sites. Various investigations, already performed in the same field, have confirmed the applicability of the considered technique and the feasibility of the proposed experiment. Besides determining the major components of the analyzed fragments, some trace elements, such as Sb, As and Ag, have also been identified. The compositions of the different samples have been also compared, in order to gain information regarding possible workshops and provenance. The comparative analysis will be useful, moreover, to establish an eventual classification according to the chemical composition. The obtained results are complementary to those already achieved for the considered objects, including atomic absorption, atomic emission and neutron diffraction

[moving And Lifting Patients: Postural And Ergonomic Aspects].

The most dangerous and difficult tasks faced by health workers are those procedures involved with lifting and moving patients. Therefore, training and recycling programs in lifting procedures are a compulsory part of programs for the prevention of musculoskeletal disorders in schools and health institutions. The present study presents basic and innovative orientation with an ergonomic approach regarding these procedures, together with the use of devices.34165-7

PIXE Investigation of Ancient Linen Fabrics Dated from Old Kingdom to Ptolemaic Ages (2200-300 B.C.)

External milli-beam particle induced X-ray emission spectroscopy (PIXE) has been used as non-destructive technique to investigate ancient linen fabrics from pre-dynastic and Ptolemaic ages belonging to the archaeological collections of the Egyptian Museum of Turin and to the Civic Archaeological Museum of Bologna, Italy. 9 linen fabric samples dated from Old Kingdom to Ptolemaic ages (2200-300 B.C.) were investigated, as well as 5 modern linen fabric samples, added for comparison. The primary goal of this work has been to advance the correct material description of the fabrics providing scientific data for further and more comprehensive comparative analyses. PIXE has provided quantitative analyses for the major (Si, Cl, K, Ca and Fe) and minor or trace elements as P, Ti and Mn, supplying information on the near-surface elemental composition. The achieved results contribute to comprehend the structural basis for the chemical properties of the considered materials, as well as to set up a classification according to the chemical composition, allowing in general a better understanding of the studied linen cloths

The role of demoralization and hopelessness in suicide risk in schizophrenia: a review of the literature

Background and Objectives: Demoralization has been defined by hopelessness and helplessness attributable to a loss of purpose and meaning in life. Demoralization is a meaningful mental health concern, frequently associated with suicide risk in medical and psychiatric patients. The aim of this systematic review was to synthesize the recent empirical evidence on demoralization in patients with schizophrenia and to better understand the relationship between demoralization and suicide risk in patients with schizophrenia. Methods: A comprehensive literature search using key words and subject headings was performed following PRISMA guidelines with several bibliographic databases, resulting in the identification of 27 studies. Results: The findings suggested that demoralization is prevalent in patients with schizophrenia and supported the hypothesis that the association between depression and suicide is moderated by hopelessness. In clinical practice, it is important to recognize symptoms of demoralization using appropriate psychological tools to better understand the suffering of patients with schizophrenia and to implement suicide prevention programs

Granite Dust Is the Possible Component of the Dry Construction Mixtures

This paper is devoted to research of possibility of utilization of granite dust. It is shown that the granite dust from the crushing screenings of "Shartashskiy stone-crushed stone quarry" can be recommended as a filler for the production of dry building mixes for flooring. With the introduction of dust in the amount of 20 % by weight of cement it is possible to obtain the mortar of the class not less B12.5

Nanoscale investigation of polymer cement concretes by small angle neutron scattering

An analysis of dense cements, such as polymer cement concrete, is made to produce original innovative components for different types of constructing materials. These materials present good functional properties (ageing resistance, crack formation resistance, hardness, and stability of mechanical modules) and can be used for various applications. In this paper, experimental tests on Portland cement with added γ-Al 2 O 3 and redispersible dry polymer performed using small angle neutron scattering are reported. The objective of the investigation was to assess the key parameters of the material (e.g., porosity, fractal dimensions, and size distribution) at the nanoscale level as well as to obtain useful structural information for expanding the possibility of applications. The results obtained can contribute to the optimisation of the consistency of the material, the design of operating conditions of elements of structures and facilities, and the design of the procedures that support ecological criteria and enhance quality and safety levels. © 2017 Walter de Gruyter GmbH, Berlin/Boston

Job satisfaction mediates the association between perceived disability and work productivity in migraine headache patients

Migraine headache is the cause of an estimated 250,000,000 lost days from work or school every year and is often associated with decreased work productivity. The aim of this cross-sectional study was to assess the relationship between perceived disability, job satisfaction and work productivity in patients affected by chronic migraineurs. Participants were 98 consecutive adult outpatients admitted to the Regional Referral Headache Centre of the Sant’Andrea Hospital in Rome, Italy. Patients were administered the Italian Perceived Disability Scale, The Quality of Life Enjoyment and Satisfaction Questionnaire-Work Subscale and The EndicottWork Productivity Scale. Perceived disability is significantly associated with job satisfaction and work productivity. Job satisfaction is significantly related to work productivity and mediates the association between perceived disability and work productivity in patients affected by chronic migraineurs. Our results confirm that patients suffering from migraine headaches who have negative perceptions © 2019 by the authors. Licensee MDPI, Basel, Switzerland
