Chalcogenide Photonic Crystal Fibers for Near and Middle Infrared Applications

2007

Chalcogenide glasses are based on sulphur, selenium, tellurium and the addition of other elements such as arsenic, germanium, antimony, gallium, etc. Chalcogenide fibers present numerous applications in the IR field, such as telecommunication at 1.55 mum, spectroscopy and military systems in the two atmospherics windows (3-5 mum and 8-12 mum). One of the interests of chalcogenide glasses is to associate high non linear properties with their Infrared transmission from 0.51 mum to 12-18 mum depending on the composition. Indeed, chalcogenide glasses present high third order optical properties, 100 - 1000 times as high as the non linearity of silica glass at 1.55 mum. For many applications, sin…

Acoustic and optical variations during rapid downward motion episodes in the deep north-western Mediterranean Sea

2011

An Acoustic Doppler Current Profiler (ADCP) was moored at the deep-sea site of the ANTARES neutrino telescope near Toulon, France, thus providing a unique opportunity to compare high-resolution acoustic and optical observations between 70 and 170 m above the sea bed at 2475 m. The ADCP measured downward vertical currents of magnitudes up to 0.03 m s-1 in late winter and early spring 2006. In the same period, observations were made of enhanced levels of acoustic reflection, interpreted as suspended particles including zooplankton, by a factor of about 10 and of horizontal currents reaching 0.35 m s-1. These observations coincided with high light levels detected by the telescope, interpreted …

Managing electrical energy storage systems and shiftable loads with an innovative approach in energy districts

2014

In this work, a power dispatch problem for a system composed of an aggregate of loads and an electrical energy storage system is considered. The approach to solve the optimal dispatch is innovative and shows good performances in limited calculation times. According to the more recent indications coming from the European distributors, the architecture for energy dispatch at distribution level will be hierarchical. The 'Aggregator' is the interface between groups of loads and the energy distributor and sends the individual consumers the desired load profiles, following which the user may gets a discount on the energy bill. On the other hand, the energy tariff may follow a given daily profile …

Where do you live? North versus Central-South differences in relation to Italian patients with oral lichen planus: a cross-sectional study from the S…

2022

Abstract Background Oral lichen planus (OLP) is an immune-mediated inflammatory chronic disease of the oral mucosa, with different patterns of clinical manifestations which range from keratotic manifestations (K-OLP) to predominantly non-keratotic lesions (nK-OLP). The aim of the study was to analyze the differences in the clinical, psychological profile and symptoms between Italian patients of the North and Central-South with K-OLP and nK-OLP. Methods 270 K-OLP and 270 nK-OLP patients were recruited in 15 Italian universities. The Numeric Rating Scale (NRS), Total Pain Rating Index (T-PRI), Hamilton Rating Scales for Depression and for Anxiety (HAM-D and HAM-A), Pittsburgh Sleep Quality In…

Seniority rules, worker mobility and wages : evidence from multi-country linked employer-employee data

2018

We construct multi-country employer-employee data to examine the consequences of last-in, first-out rules. We identify the effects by comparing worker exit rates between different units of the same firms operating in Sweden and Finland, two countries that have different seniority rules. We observe a relatively lower exit rate for more senior workers in Sweden in the shrinking firms and among the low-wage workers. These empirical patterns are consistent with last-in, first-out rules in Sweden providing protection from dismissals for the more senior workers among the worker groups to whom the rules are most relevant. Similarly, we observe a steeper seniority-wage profile in Sweden, suggesting…

How perceived changes in the ethical culture of organizations influence the well-being of managers: A two-year longitudinal study.

2015

The first aim of this study was to identify long-term patterns of ethical organizational culture based on the perceptions of 368 Finnish managers over a period of two years. The second aim was to investigate whether there is a difference in the long-term occupational well-being (burnout and work engagement) of managers exhibiting different patterns of ethical culture. Based on latent profile analysis, five different patterns of the strength of ethical culture were identified: moderate, high, increasing, decreasing, and low. The results show that managers exhibiting either the low or decreasing pattern of ethical culture experienced significant changes in their well-being over time. Decreasi…

A job resources-based intervention to boost work engagement and team innovativeness during organizational restructuring

2018

Purpose The purpose of this paper is to investigate the effectiveness of a job resources-based intervention aimed at proactively increasing work engagement and team innovativeness during organizational restructuring using a person-centered approach. Design/methodology/approach The intervention was conducted in two organizations: two departments served as participants (n=82) and two as controls (n=52). The aim was to first identify sub-groups of employees with different developmental patterns of work engagement, and then to determine whether these sub-groups benefited differently from the intervention with respect to team innovativeness and work engagement. Findings Latent profile analysis …

Comparison of stir bar sorptive extraction in the liquid and vapour phases, solvent-assisted flavour evaporation and headspace solid-phase microextra…

2017

The volatile fraction plays an important role on the organoleptic properties and overall acceptability of fruit juices. This work reports for first time a non-targeted approach for the analysis of the volatile fraction of fruit juice by stir bar sorptive extraction (SBSE[1]) in liquid and vapour phase (HSSE[2]) at three extraction times (30, 60, and 120 min), two temperatures (room temperature and 40 °C), and two sample volumes (5 and 10 mL). The resultant volatile profiles were compared with solvent-assisted flavour evaporation (SAFE[3]) and headspace solid-phase microextraction (HS-SPME[4]). SBSE and HSSE enabled the detection and identification of more compounds than HS-SPME and less tha…

Influence of clinical and psychological variables upon the oral health-related quality of life in patients with temporomandibular disorders

2017

Background To analyze the association between the OHIP-14 and the different subtypes making up the clinical and psychological axis obtained using the RDC/TMD. Material and Methods 407 patients treated at the TMD unit of the Andalusian Healthcare Service were administered the Spanish version of the Research Diagnostic Criteria for Temporomandibular Disorders questionnaire (RDC/TMD), together with the Oral Health Impact Profile questionnaire (OHIP-14). The degree of association between the patients’ score in the OHIP-14 and the clinical and biopsychosocial variables was analyzed through bivariate and multivariate analyses, specifically through linear regression. Results 89.4% of the treated p…
