A mechanical picture of fractional-order Darcy equation
2015
Abstract In this paper the authors show that fractional-order force-flux relations are obtained considering the flux of a viscous fluid across an elastic porous media. Indeed the one-dimensional fluid mass transport in an unbounded porous media with power-law variation of geometrical and physical properties yields a fractional-order relation among the ingoing flux and the applied pressure to the control section. As a power-law decay of the physical properties from the control section is considered, then the flux is related to a Caputo fractional derivative of the pressure of order 0 ⩽ β ≤ 1 . If, instead, the physical properties of the media show a power-law increase from the control sectio…

Aesthetic perception of single implants placed in the anterior zone. A cross-sectional study
2016
Background: Several aesthetic indexes have been described to assess implant aesthetics. The aim of this study was to compare the aesthetic assessment made by dental professionals and students of single-tooth implants placed in the upper incisors. Material and Methods: A cross-sectional survey study using a subjective questionnaire to assess the aesthetics in 3 implant supported single-tooth cases in the anterior maxilla was performed. The interviewed subjects were divided into 4 groups: dentists with experience in implant treatment, dentists without experience in implants and 3rd and 5th year dental students. The questionnaire consisted of 2 visual analogue scales (VAS) to evaluate aestheti…
PARASITES AND SEXUAL REPRODUCTION IN PSYCHID MOTHS
2004
Persistence of sexual reproduction among coexisting asexual competitors has been a major paradox in evolutionary biology. The number of empirical studies is still very limited, as few systems with coexisting sexual and strictly asexual lineages have been found. We studied the ecological mechanisms behind the simultaneous coexistence of a sexually and an asexually reproducing closely related species of psychid moth in Central Finland between 1999 and 2001. The two species compete for the same resources and are often infected by the same hymenopteran parasitoids. They are extremely morphologically and behaviorally similar and can be separated only by their reproductive strategy (sexual vs. as…
Just in case, just in time, or just don't bother? Assessment of one-shot library instruction with follow-up workshops
2015
Published version from the journal: LIBER Quarterly. Available from the publisher at: http://liber.library.uu.nl/index.php/lq/article/view/URN%3ANBN%3ANL%3AUI%3A10-1-116866 This article examines if the timing of library instruction courses is an important part of how students experience library instruction as a means of developing information literacy skills. Two student groups, belonging to different academic subjects, have received the same training and the same assessment questionnaire afterwards. One of the groups was in the middle of writing their student thesis as a part of their final year of their bachelor degree work, the other group consisted of different subjects within the human…
Impact of fixed orthodontic appliances on quality of life among adolescents in India
2014
Context: Malocclusion can seriously impair quality of life and they may affect various aspects of life, including function, appearance, interpersonal relationships and even career opportunities. Objectives: To assess and determine various factors that may influence the impact of orthodontic treatment on the quality of life of adolescents. Study design: Cross sectional study in adolescents of Moradabad was conducted on 109 males and 113 females (n=222) adolescents having a fixed orthodontic appliance, aged 13 to 22 years (mean 17.5±1.5). A pre-structured questionnaire designed by Mandall et al, with nine conceptual impact sub-scales to highlight the problem faced by the patient in daily life…
The importance of horizontal-fit of university student jobs for future job quality
2019
Purpose The purpose of this paper is to gain a better understanding of the antecedents of the quality of graduates’ jobs when they enter the job market after university graduation. Design/methodology/approach Survey data collected from 173 Spanish bachelor and master’s degree university graduates at two time points (two months before and six months after graduation, approximately) were analyzed by means of path analysis. Findings A moderated mediation model was tested, where the relationship between the horizontal fit (HF) between the university degree subject and the student’s job and the quality of the graduate’s job after graduation is mediated by self-perceived employability and modera…
Probabilités d’orientation déjouées par le sport : le cas des étudiantes à l’université
2022
Introduction En 2020, les femmes restent sous-représentées dans le monde du sport, aussi bien parmi les pratiquantes, plus encore parmi les sportives de haut niveau, les dirigeantes et présidentes de fédérations sportives. Dans ce contexte, la dimension sportive des étudiantes à l’université leur confère un profil « atypique ». Les unes choisissent le domaine d’étude dédié aux métiers du sport, les STAPS (sciences et techniques des activités physiques et sportives), représentant le tiers des ...
Comparative analysis of impacted upper canines: Panoramic radiograph Vs Cone Beam Computed Tomography.
2016
Background The use of CBCT exam in the study of IMC is not new. However, it's still not known in what specific aspects CBCT exam shows a better result than then conventional exams. The aim of this study was to compare and conclude in what way the opinion regarding upper canine impaction differed when observing a panoramic image compared to the observation of a set of CBCT reconstructions. Material and Methods Twenty patients (10 males and 10 females) with a total of 28 impacted maxillary canines were identified from the database of the Department of Dentistry, Faculty of Medicine, University of Coimbra. For each canine, two different images were available: a panoramic image and a set of CBC…
Validity and reliability of the Palliative Care Transition Measure for Caregivers (PCTM-C).
2018
AbstractObjectivePatients suffering from advanced disease face different care transitions. The transition from acute to palliative care is challenging and may lead to the discontinuity of care. Family caregivers become important sources of information, as patients begin to experience difficulties in coping with emotional transition events. The Care Transition Measure was developed to evaluate care transitions as experienced by the elderly. It has never been used in palliative care. The aim of this study was to test the validity and reliability of a modified version of the Palliative Care Transition Measure, specifically the Palliative Care Transition Measure for Caregivers (PCTM-C).MethodTh…
