Mean Radiant Temperature Measurements through Small Black Globes under Forced Convection Conditions

2021

One of the most critical variables in the field of thermal comfort measurements is the mean radiant temperature which is typically measured with a standard 150 mm black globe thermometer. This is also the reference instrument required for the assessment of heat stress conditions by means of the well-known Wet Bulb Globe Temperature index (WBGT). However, one of the limitations of this method is represented by the relatively long response time. This is why in recent years there has been a more and more pressing need of smart sensors for controlling Heating Ventilation and Air Conditioning (HVAC) systems, and for pocket heat stress meters (e.g., WBGT meters provided with table tennis balls). …

Detection of Water Stress in an Olive Orchard with Thermal Remote Sensing Imagery

2006

An investigation of the detection of water stress in non-homogeneous crop canopies such as orchards using high-spatial resolution remote sensing thermal imagery is presented. An airborne campaign was conducted with the Airborne Hyperspectral Scanner (AHS) acquiring imagery in 38 spectral bands in the 0.43–12.5 mm spectral range at 2.5 m spatial resolution. The AHS sensor was flown at 7:30, 9:30 and 12:30 GMT in 25 July 2004 over an olive orchard with three different water-deficit irrigation treatments to study the spatial and diurnal variability of temperature as a function of water stress. A total of 10 AHS bands located within the thermal-infrared region were assessed for the retrieval of…

Transmural myocardial ischaemia complicating recovery after dobutamine-atropine stress echocardiography in patients with non-significant coronary art…

2011

In the proposed selection of cases, traditional imaging is integrated with contemporary diagnostic tools available in the cath-lab to navigate the potential mechanisms underlying a very rare complication occurring in the recovery phase of dobutamine-atropine stress echocardiography. The data, collected in a time frame of nearly 15 years, provide interesting elements to possibly evolve from speculative considerations to plausible confirmation of the candidate pathophysiological mechanism mediating the occurrence of transmural myocardial ischaemia after beta-blockers administration.

Comorbilidad de TEA y TDAH: revisión sistemática de los avances en investigación

2016

La reciente publicación del DSM-5, introduce la novedad de aceptar la posibilidad de un diagnóstico comórbido de los Trastorno de Espectro Autista (TEA) y el Trastorno por Déficit de Aten- ción/Hiperactividad (TDAH). En este artículo se realiza una revisión de trabajos que han estudiado esta comorbilidad. Se revisaron un total de 28 investigaciones, estableciendo 4 temáticas diferentes. La investigación muestra tasas variables de comorbili- dad de TEA y TDAH dependiendo de la edad y procedencia de las mues- tras, y de los criterios diagnósticos empleados. Cuando se da la comorbili- dad de TEA y TDAH aumenta la severidad de la sintomatología autista y de trastornos externalizantes e internal…

Transforming Experience: The Potential of Augmented Reality and Virtual Reality for Enhancing Personal and Clinical Change

2016

During life, many personal changes occur. These include changing house, school, work, and even friends and partners. However, the daily experience shows clearly that, in some situations, subjects are unable to change even if they want to. The recent advances in psychology and neuroscience are now providing a better view of personal change, the change affecting our assumptive world: (a) the focus of personal change is reducing the distance between self and reality (conflict); (b) this reduction is achieved through (1) an intense focus on the particular experience creating the conflict or (2) an internal or external reorganization of this experience; (c) personal change requires a progression…

Influence of the passive film properties and residual stresses on the micro-electrochemical behavior of duplex stainless steels

2010

In the present paper, the chemical composition of passive films formed on both phases of two types of duplex stainless steels (UNS S31803 and UNS S32304) is determined at the micro-scale using Auger electron spectroscopy (AES). Samples were either mechanically polished (down to diamond pastes) or electrochemically etched in acidic solutions. The micro-electrochemical behavior of samples was then determined in sodium chloride media by means of the electrochemical micro-cell technique (capillary diameters of 30 μm). The results obtained were analyzed considering the passive film chemical composition. Quantitative relationships between electrochemical parameters and the distribution of chromiu…

Study of the mechanical effects on passivity breakdown by local probe techniques

2006

This paper aims at demonstrating that a relationship exists between surface stress and pitting corrosion. The surface stress field generated by polishing was first calculated using a thermo-mechanical model and a finite element code. Pitting corrosion tests performed at the microscale along the austenite/ferrite interface using the electrochemical microcell technique were then analyzed considering the microstructure and the residual surface stress field. Mechano-chemical criteria are proposed leading to an enhancement of pitting corrosion of duplex steels.

Saikne starp stresu un izdegšanu autiskā spektra traucējumu bērnu vecākiem

2020

Ievads. Autiskā spektra traucējumi (AST) biežāk raksturojas ar agrīnu sākumu. Galvenie raksturlielumi ir traucējumi sociālajā komunikācijā un sociālajā mijiedarbībā, ko papildina ierobežota un atkārtojoša izturēšanās. Attiecīgi šāda milzīga uzmanība, ko bērns pieprasa, varētu sekmēt vecāku izdegšanas pazīmes. Darba mērķis. Ir identificēt izdegšanas faktorus, kas ietekmē autisma spektra bērnu vecāku ikdienas dzīvi. Metodes un materiāli. Šķērsgriezuma pētījumā tika iesaistīti 76 bērnu ar autiska spektra traucējumu vecāki, kuri pilnīgi anonīmi aizpildīja aptaujas. Pielietotās aptaujas bija demogrāfiskā aptauja, Široma-Melameda izdegšanas mēra aptauja, un Stresa skala, kura tika izveidota no Pe…

Neuropsychological Profile, Emotional/Behavioral Problems, and Parental Stress in Children with Neurodevelopmental Disorders

2021

Background: The aim of our study was to trace a specific neuropsychological profile, to investigate emotional-behavioral problems and parental stress in children with Autism Spectrum Disorder Level 1/High functioning (ASD-HF), Specific Learning Disorders (SLD) and Attention Deficit/Hyperactivity Disorder (ADHD) disorders and to highlight similarities and differences among the three groups. Methods: We retrospectively collected the data from a total of 62 subjects with ASD-HF (n = 19) ADHD (n = 21), SLD (n = 22) and 20 typical development. All the participants underwent neuropsychological standardized test for the evaluation of cognitive profile (Wechsler Intelligence Scale for Children Four…
