Microtomographic reconstruction of mandibular defects treated with xenografts and collagen-based membranes:a pre-clinical minipig model

2021

Background The goal of this study was to evaluate hard tissue response following guided bone regeneration using commercially available bovine bone grafts and collagen membranes; bilayer collagen membrane and porcine pericardium-based membrane, by means of a non-destructive three-dimensional (3D) computerized volumetric analysis following microtomography reconstruction. Material and Methods Bone regenerative properties of various bovine bone graft materials were evaluated in the Göttingen minipig model. Two standardized intraosseous defects (15mm x 8mm x 8mm) were created bilaterally of the mandible of eighteen animals (n=72 defects). Groups were nested within the same subject and randomly d…

Managing Human Factors to Reduce Organisational Risk in Industry

2018

[EN] Human factors are intrinsically involved at virtually any level of most industrial/business activities, and may be responsible for several accidents and incidents, if not correctly identified and managed. Focusing on the significance of human behaviour in industry, this article proposes a multi-criteria decision-making (MCDM)-based approach to support organizational risk assessment in industrial environments. The decision-making trial and evaluation laboratory (DEMATEL) method is proposed as a mathematical framework to evaluate mutual relationships within a set of human factors involved in industrial processes, with the aim of highlighting priorities of intervention. A case study relat…

The behaviour of non consumer of organic food: suggestions on marketing strategies to attract new market segments

2013

Oggi le produzioni agricole biologiche sono in netta crescita sia a livello internazionale che nazionale. Tra le regioni italiane la Sicilia rappresenta la principale area di produzione e si colloca all’ultimo posto relativamente ai consumi. Attraverso un’indagine pilota nella citta di Palermo, si e voluto indagare, sui motivi del mancato acquisto di prodotti biologici per comprendere quali sono le leve del marketing mix su cui e possibile intervenire per attrarre nuovi segmenti di mercato. L’indagine e stata realizzata intervistando un campione di non-consumatori di alimenti biologi presso alcuni supermercati della citta. I campioni, degli intervistati e dei supermercati, sono stati selezi…

Do Pied Flycatcher Females Defend an Extra Nest Hole Against Conspecific Females?

1999

AbstractIn birds, females are often aggressive against conspecific females during the breeding. There are many explanations for this intrasexual aggression by females: e.g., nest site or food resource defence, prevention of intraspecific brood parasitism or infanticide, and monopolization of paternal care. A pair might also benefit by defending an alternative nest site in addition to the current nest site. Here, I study by experimentation whether pied flycatcher (Ficedula hypoleuca) females defend an extra nest box as an alternative nesting site. Further, I examine whether females behave differently when their mate is present vs not present. I measured the reactions by resident females to a…

Tensile behaviour of anti-symmetric CFRP composite

2011

Abstract This paper addresses the response of a 17-ply anti-symmetric carbon/epoxy composite subjected to uniaxial tensile loading. Hashin ply damage model is adopted to describe the damage behaviour of the plies, whereas damage initiation and progression of the interfaces are characterised by mixed-mode cohesive damage model. Force-displacement curves obtained numerically and experimentally show good agreement. Results show that all laminae and interfaces experience the damage except laminae with 0o fibre. In addition, damage is concentrated at the tab and central regions of the tensile specimen. Edge delamination is observed in all interfaces.

Relationships among Bicycle Rider Behaviours, Anger, Aggression, and Crashes in Finland

2022

Riding a bicycle is increasingly encouraged as a sustainable transport solution, especially in urban areas. However, safety concerns, both perceived and actual, can significantly lower the willingness to ride among the population. To support cycling planning and policy in the double task of increasing the levels of cycling while mitigating crash risk, there is a need to better understand the behaviours and attitudes of bicycle riders. In this manuscript, we study a cohort of Finnish bicycle riders through four questionnaires, the Cycling Behaviour Questionnaire (CBQ), Cyclist Risk Perception and Regulation Scale (RPRS), Cyclist Anger Scale (CAS), and Cyclist Aggression Expression Inventory …

Data from: Survival relative to new and ancestral host plants, phytoplasma infection and genetic constitution in host races of a polyphagous insect d…

2015

Dissemination of vectorborne diseases depends strongly on the vector's host range and the pathogen's reservoir range. Because vectors interact with pathogens, the direction and strength of a vector's host shift is vital for understanding epidemiology and is embedded in the framework of ecological specialization. This study investigates survival in host-race evolution of a polyphagous insect disease vector, Hyalesthes obsoletus, whether survival is related to the direction of the host shift (from field bindweed to stinging nettle), the interaction with plant-specific strains of obligate vectored pathogens/symbionts (stolbur phytoplasma), and whether survival is related to genetic differentia…

Role of two co-occurring Mediterranean sea urchins in the formation of barren from Cystoseira canopy

2015

Abstract In the Mediterranean Sea the co-occurring sea urchins Paracentrotus lividus and Arbacia lixula are usually considered to share the same ecological role in the formation of barren from Cystoseira canopy. However, their foraging ability may vary due to feeding behavior and species-specific morphological traits. The relative effects of P. lividus and A. lixula on Cystoseira canopy was tested experimentally both in the laboratory, at a density of about 20 ind./m 2 , and in the field by gut content analysis. Field and laboratory results show that A. lixula is unable to affect Cystoseira spp. Furthermore, these results confirmed the great ability of P. lividus to consume Cystoseira canop…

Challenging behaviour in school – special education teachers’ perceptions

2016

This article explores the challenges that special education teachers encounter during their daily work in Finnish schools. The main focus is in those challenges which cause worry among teachers, especially aggressive behavior in class rooms and school area. This article scrutinizes the reasons and consequences of a problem from the perspective of special education teachers. The research shows, how problems are mainly caused by delays in assessments, treatments and rehabilitation for pupils with mental or behavioral disorders. The analysis shows how on teachers’ opinion, challenging situations, which induce great worry occur when pupil has a need for psychiatric treatment but had not receive…
