AR/VR Contextualization of the Statue of Zeus from Solunto

2022

The aim of the research is to test how VR and AR technologies can contribute to a virtuous reconnection between the museums, where archaeological works of art are exhibited, and the sites where these works come from. The connection between the museum and the site will be operated with panoramic images generated with SfM photogrammetric tools; these images will set up a twofold reconnection: i) between the work of art and the building where it was hosted; ii) between the building and the site, with the landscape around. The connection between the site and the museum will be operated with Augmented Reality, through the visualization on site of the works of Art exhibited in the archaeological …

Spin Crossover and Long-Lived Excited States in a Reduced Molecular Ruby.

2020

Abstract The chromium(III) complex [CrIII(ddpd)2]3+ (molecular ruby; ddpd=N,N′‐dimethyl‐N,N′‐dipyridine‐2‐yl‐pyridine‐2,6‐diamine) is reduced to the genuine chromium(II) complex [CrII(ddpd)2]2+ with d4 electron configuration. This reduced molecular ruby represents one of the very few chromium(II) complexes showing spin crossover (SCO). The reversible SCO is gradual with T 1/2 around room temperature. The low‐spin and high‐spin chromium(II) isomers exhibit distinct spectroscopic and structural properties (UV/Vis/NIR, IR, EPR spectroscopies, single‐crystal XRD). Excitation of [CrII(ddpd)2]2+ with UV light at 20 and 290 K generates electronically excited states with microsecond lifetimes. This…

Steroidal supramolecular metallogels

2020

The review deals with an expanding number of steroidal compounds that are capable of forming a metallogel providing a multitude of novel materials rich in their properties. The future of steroidal metallogels holds a myriad of potential applications as new intelligent materials. Detection of potentially harmful compounds without expensive instrumentation, entrapment of environmentally hazardous substances, and sensitive and selective nanomaterials represent only a few of these potential applications. This article reviews the design, synthesis, characterization, and applications of steroidal metallogels. peerReviewed

Stimula kontrasta un virziena ietekme uz sakādisko acu kustību parametriem

2022

Darbs ir uzrakstīts latviešu valodā uz 41 lapaspusēm. Tas satur 25 attēlus, 2 tabulas, 3 pielikumus un 46 atsauces uz literatūras avotiem. Darba mērķis ir novērtēt stimula kontrasta un virziena ietekmi uz sakāžu parametriem (sakādisko acu kustību latences, precizitātes un maksimālā ātruma rādītājiem). Pētījumā piedalījās 15 dalībnieki (no 21 līdz 29 gadiem). Acu kustibas tika pierakstītas ar Tobii Pro Fusion acu kustību pieraksta iekārtu (250Hz). Sakādisko acu kustību stimuli ar dažādiem kontrasta līmeņiem tika demonstrēti uz četriem dažādiem foniem četros dažādos virzienos. Rezultāti norāda būtisku stimula virziena ietekmi uz latenci un maksimālo ātrumu pelēkā fonā 30 cd/m2 (negatīva un po…

Distress, Eustress, or No Stress? Explaining Smartphone Users' Different Technostress Responses

2018

Technostress is common and has harmful consequences. Therefore, researchers have shown increasing interest in explaining technostress in the field of information systems (IS). While extant research merits in identifying the causes and consequences of technostress, it has not explained empirically why information technology (IT) users have different responses to similar potentially stressful IT events. Indeed, events such as smartphone failures can derive negative distress responses for some users and positive eustress responses for others. To address this gap in research, we conducted a qualitative study by interviewing users who had experienced smartphone failures. As a contribution, our f…

Using uncertain preferential information from stakeholders to assess the acceptability of alternative forest management plans

2017

In forest management planning, participatory planning processes are often encouraged as a means to acquire relevant information and to enhance the stakeholders' acceptability of alternative plans. This requires the aggregation of the stakeholders' preferences that can be done in a wide variety of manners. The aggregation process strives to reduce the information into a single set of preferences that simplifies the information and allows for the use of discrete decision support tools. Depending on how the preferences are aggregated, a wide range of plan rankings can emerge. Although this range of ranking complicates the issue of plan selection, it does highlight the uncertainty involved in a…

Results of a dental care protocol for mentally handicapped patients set in a primary health care area in Spain

2007

Objective: Disabled people have the same right as other people to receive the health care they need, but they sometimes have difficulties to achieve it. In Castilla y Leon it has come into effect a law to guarantee Primary and Secondary Care coordination to provide dental treatment under sedation or anaesthesia to mentally disabled people who need it. Our aim is to evaluate the results of the implementation of such a law through a specific protocol in our health setting. Study design: Descriptive, made in a Health Area over a year, on mentally disabled people who were sent to hospital for treatment under anaesthesia after Primary Dental Care Units assessment. It has been studied the age, ge…
