Oral manifestations in patients with gastro-oesophageal reflux disease: a single-center case-control study

2008

OBJECTIVE: To assess the occurrence of oral pathological changes and symptoms in patients affected by gastro-oesophageal reflux disease (GERD). PATIENTS AND METHODS: 200 patients with GERD and 100 matched healthy controls were studied. Thorough visual examination of the dental and oral mucosal tissues was performed and medical history relevant to oral symptoms was collected. The primary outcome was defined as a statistically significant difference, between the study group and controls, in the presence of the following indicators: soft/hard palate and uvula erythema, tooth wear, xerostomia, oral acid/burning sensation, subjective halitosis and dental sensitivity. Statistical analysis include…

Impact of burn-out syndrome in oncology staff and its improvement through specific interventions.

2019

249 Background: Burn-Out Syndrome (BOS) is defined by: emotional and physical exhaustion; cynicism and depersonalization; and no personal nor professional fulfillment. With increasing incidence, it impacts negatively in the patient attention quality and the quality of institutional processes. Few experiences reported about its incidence and impact in Medical Oncology. Lack of resources for its diagnosis and management. Our objective was to determine the incidence of the BOS in our workers, analyze its causes and try to reduce in 20% the percentage of workers suffering or at risk of suffering BOS. Developed as a Quality Training Program (ASCO - ECO Foundation) project. Methods: 23 nurses/nu…

Excitonic energy level structure and pigment-protein interactions in the recombinant water-soluble chlorophyll protein. II. Spectral hole-burning exp…

2011

Persistent spectral hole burning at 4.5 K has been used to investigate the excitonic energy level structure and the excited state dynamics of the recombinant class-IIa water-soluble chlorophyll-binding protein (WSCP) from cauliflower. The hole-burned spectra are composed of four main features: (i) a narrow zero-phonon hole (ZPH) at the burn wavelength, (ii) a number of vibrational ZPHs, (iii) a broad low-energy hole at ~665 and ~683 nm for chlorophyll b- and chlorophyll a-WSCP, respectively, and (iv) a second satellite hole at ~658 and ~673 nm for chlorophyll b- and chlorophyll a-WSCP, respectively. The doublet of broad satellite holes is assigned to an excitonically coupled chlorophyll dim…

The Anagyrus (Hymenoptera: Encyrtidae) parasitoids of the obscure mealybug Pseudococcus viburni (Hemiptera: Pseudococcidae) in Spain, with descriptio…

2021

The presence of three species of the genus Anagyrus Howard (Hymenoptera: Encyrtidae) parasitizing the obscure mealybug Pseudococcus viburni (Signoret) (Hemiptera: Pseudococcidae) in agricultural ecosystems of citrus, persimmon and ornamental plants from Eastern Spain is recorded. Anagyrus aligarhensis Agarwal & Alam is recorded for the first time as parasitoid on this mealybug. Anagyrus fusciventris (Girault) is a new record for Spain. Anagyrus borrianensis sp. nov., reared as a specific primary parasitoid of this mealybug, is described and illustrated. The joint presence of Anagyrus pseudococci (Girault) and Anagyrus vladimiri Triapitsyn on citrus crops is confirmed. A key to species o…

Abstract Understanding the factors related to teacher burnout helps in creating schools which foster teachers’ job satisfaction and the delivery of high-quality education. We studied teacher burnout and its three subdomains across several teacher-, student-, and organisation-level variables, including teacher category, class size, number of students with support needs, attitudes towards inclusive education, and availability of support. The participants were 4567 Finnish primary school teachers consisting of 2080 classroom teachers, 1744 subject teachers, 438 special-class and 305 resource room teachers. Several associations between teacher burnout and the background variables were observed …

Prevalence of burnout in a sample of Brazilian teachers

2011

Background and Objectives: Burnout is a psychological response to chronic work-related stress of an interpersonal and emotional nature. Brazilian law have already contemplated burnout syndrome as a mental and behavioural disorder related to work. The aim of this study was to identify the prevalence of burnout in a sample of Brazilian teachers. Methods: The sample was composed of 714 teachers from 8 schools in Porto Alegre and its metropolitan area (Brazil). The levels of burnout were evaluated by the Spanish Burnout Inventory, educational version (SBI-Ed). In addition, Psychosomatic disorders were estimated by the UNIPSICO subscale. Results: The percentage of participants who indicated high…

Introduzione a: FUOCO E CARBONE : le tradizioni dei carbonai

2022

L'introduzione al volume: Fuoco e carbone. Le tradizioni dei carbonai sottolinea un’accorta indagine sul lavoro dei carbonai sardi, sulle fasi di produzione del carbone, sull’influenza che hanno avuto le maestranze toscane nel trasferimento di competenze e abilità sui carbonai locali, sul rapporto uomo-mondo vegetale che trovava massima espressione nel “processo di personificazione” della carbonaia con l’attribuzione di nomi e appellativi. Lo studio indaga, inoltre, le prime attestazioni di utilizzo del fuoco da parte degli uomini e gli impieghi ergologici e sociali che proprio il fuoco ha assunto nel tempo, la sua dimensione simbolica, quella linguistica, l’universo eterogeneo di pratiche …

Acoustic spectral hole-burning in a two-level system ensemble

2020

AbstractMicroscopic two-level system (TLS) defects at dielectric surfaces and interfaces are among the dominant sources of loss in superconducting quantum circuits, and their properties have been extensively probed using superconducting resonators and qubits. We report on spectroscopy of TLSs coupling to the strain field in a surface acoustic wave (SAW) resonator. The narrow free spectral range of the resonator allows for two-tone spectroscopy where a strong pump is applied at one resonance, while a weak signal is used to probe a different mode. We map the spectral hole burnt by the pump tone as a function of frequency and extract parameters of the TLS ensemble. Our results suggest that det…

Nature of the non-exponential primary relaxation in structural glass-formers probed by dynamically selective experiments

1998

Several experimental methods feature the potential to distinguish between slow and fast contributions to the non-exponential, ensemble averaged primary response in glass-forming materials. Some of these techniques are based on the selection of subensembles using multi-dimensional nuclear magnetic resonance, optical bleaching, and non-resonant spectral hole burning. Others, such as the time-dependent solvation spectroscopy, measure microscopic responses induced by local perturbations. Using several of these methods it could be demonstrated for various glass-forming materials that the non-exponential relaxation results from a superposition of dynamically distinguishable entities. The experime…

Foreign Language Teacher Burnout: A Research Proposal

2011

Burnout is a serious psychological syndrome that can affect not only an individual’s well-being, but also the functioning of whole organisations, such as schools. It consists of three basic stages: exhaustion, depersonalization, and reduced personal accomplishment. Not only personal variables, but also work-setting characteristics influence burnout. The teaching profession is claimed to be extremely demanding, hence teachers seem to be prone to burnout. This may be the reason why the syndrome has already been investigated in reference to teachers of various subjects or school levels. Yet, there has been no research to date attempting to investigate burnout in foreign language teachers. It m…
