Getting through the mourning process is an almost banal imperative considered necessary after the death of a loved one. But is it really self-evident ? Is letting go of those who have died a normal and inescapable ideal if we do not want to suffer too much ? No, says Vinciane Despret in a book of accounts from those who, on the contrary, have chosen not to completing the mourning process and invented a thousand different ways to live with their dead.

It is widely recognized that living day to day with a family member with Alzheimer's disease is a difficult situation for the relatives. Burden generated by this disease can lead to psychological and physical exhaustion for the caregiver, called burnout. Several health studies have shown that caregivers are a population at risk, particularly in terms of depressive symptoms (Covinsky et al., 2003), psychological distress (Pinquart and Sörensen, 2003) or health problems (Schulz et al., 1997). They also present a higher risk of mortality than noncaregivers (Schulz and Beach, 1999). Given these results, we understand the major interest of establishing support program to offer therapeutic monitoring for people caring for a relative with dementia. We present Mrs C.G’s case study, who followed the counselling program developed by Adam et al. (2009). This program aims to meet the specific demands of the caregiver by providing informative elements about the disease, relevant advice based on cognitive functioning through the specific profile of the patient and real daily challenges experienced by the caregiver. The “stress management approach” proposed by Zarit et al. (1987) induces the use of coping strategies focused on problem solving. The comparison between pre and post-intervention brings us positive elements, particularly in enhancement of the caregiver’s quality of life, of his sense of competence and efficiency in managing the disease on a daily basis. About burnout, which was the primary focus this intervention, we find that emotional exhaustion tends to decrease during the counselling sessions. A particularly important finding relates to family changes made throughout the therapy, questioning the organization of family dynamics. These positive results show the importance of developing support programs for caregivers adapted to their needs. Moreover, training therapists for this purpose seems essential because it requires a comprehensive and holistic clinical approach, given the neuropsychological, cognitive behavioural and systemic components involved.

In this paper we develop a novel valuation model and methodology to value a pharmaceutical R&D project based on real options approach. The real options approach enables the possibility of optimally abandon the project before completion whenever the investment cost turns out to be larger than the expected net cash flow stream. On the other hand, the proposed model accounts for two different sources of uncertainty, those are technical and economic risk. This model incor- porates a novel economic state vector where each economic state captures the interaction among different market and economic forces using Fourier series as the particular basis for the economic function space. In this sense, Fourier series are considered as an aggregate of forces playing a relevant role in the process evolution determining the cash flow structure and also allowing us to properly define an economic scenario where the project will be developed.

Fungal biofilm is known to promote the excretion of secondary metabolites, in accordance with solid-state related physiological mechanisms. In this work, the potentialities of fungal biofilm will be investigated in the context of the production of a Gla::GFP fusion protein by Aspergillus oryzae. Since the production of this protein is under the control of the promoter glaB, specifically induced in solid-state fermentation, biofilm mode of culture is expected to enhance the global productivity. However, we found that the glaB promoter is also activated in submerged bioreactor and the fusion protein production is higher in this mode of culture. This result is related to the high shear stress leading to biomass autolysis and leakage of intracellular fusion protein into the extracellular medium. Moreover, 2D-gel electrophoresis highlights preservation of the fusion protein integrity produced in biofilm conditions whereas proteolysis strongly affects fusion protein recovery in the submerged cultures performed at high stirring rate. Fungal biofilm reactor design was then further investigated and the scale-up potentialities were evaluated. Indeed, the specific design investigated in this work involves the use of metal structured packing exhibiting a high specific area and that can be easily expanded to large-scale bioprocessing conditions.

In the field of shelving structures for the storage of goods realized adopting tubular members, an interesting connection typology to be used to fasten the vertical columns to the beams is represented by bolted connections with long bolts in shear. With reference to this kind of connections, the authors have already performed a wide experimental and numerical investigation highlighting the occurrence, in this specific case, of local buckling phenomena. In this paper, the attention is focused on the influence of local buckling on the connection resistance, which is neglected by the current version of EC3 in the prediction of the resistance of shear connections of plates. In particular, starting from the results of the experimental and numerical analyses previously performed, in the present paper a formulation for predicting the bearing resistance of the examined connection able to account for the phenomenon of local instability is set up.

Nowadays, modern codes and standards such as the (Eurocode 4, 2004) deal with the characterisation of steel–concrete composite joints in building structures, mainly under hogging bending moments in the beam. However, in sway composite frames or when the composite structure is subjected to an accidental/exceptional event such as earthquake or column loss, the beam-to-column joint may be subjected to sagging bending moment, a loading situation which is not yet covered by the codes. This paper deals with the behaviour of composite beam-to-column external joints under sagging bending moments, mainly focusing on the specific joint component “concrete slab in compression”. Indeed, if reference is made to Eurocodes, the method recommended to characterise structural joints is the component method and the “concrete slab in compression” component has been identified as the missing component to be able to apply this method to composite joints subjected to sagging bending moment. In this article, the finite element method is used to model the slab using VecTor 2 software. Through the performed numerical simulations, the behaviour of the slab is studied in detail and an analytical model is proposed. With the proposed model, it is possible to characterise the concrete slab in compression component and so, to apply the component method to predict the mechanical properties of composite joints subjected to sagging bending moment.

Nous montrons ainsi qu’une définition d’un objet mathématique n’est ni définitive, ni une simple description de l’objet. Le choix d’une définition au détriment d’une autre doit se faire à la lumière d’un projet plus global relatif à l’institution à laquelle elle appartient. [less ▲]

Anthropogenic debris (AB) contaminate oceans and affect marine organisms in several ways. Plastic production is constantly increasing and it is estimated that 10% of this production end in the seas. As a consequence, plastic is considered as an emerging contaminant and ingestions by organisms are increasingly reported. Microdebris (< 5mm) are available for a high range of organisms, including planktivorous fish, such as the European anchovy (Engraulis encrasicolus). Planktivorous fish have a particular gill basket, with long and tight gill rakers, related to their diet. Upon these gill rakers, small structures called denticles are present. These gill rakers act as a net to trap organic particles and AB. The aim of our study was to correlate sizes of AB ingested with the mesh constituted by the gill rakers and associated structures. Fifteen stomach contents were analyzed by Raman spectroscopy and particles were measured. Five gill arches were observed with a scanning electron microscope. Cellulose fibers and microplastics were the most AB ingested. Comparing to other Clupeiformes (pilchard and Atlantic herring), anchovies have more denticles on each gill rakers (personal data). AB ingestion by fish is poorly studied and impacts of AB are not much understood. Clupeiformes play a major role in marine ecosystems and is the most consumed order by humans. As the branchial basket constitutes a food selective apparatus, more morphological studies dealing with AB ingestion on Clupeiformes are needed. [less ▲]
