Platelet-rich plasma (PRP) is blood plasma with a high concentration of autologous platelets which constitute an immense reservoir of growth factors. The clinical use of PRP is widespread in various medical applications. Although highly popular with athletes, the use of PRP for the treatment of tendinopathies remains scientifically controversial, particularly due to the diversity of products that go by the name of “PRP.” To optimize its use, it is important to look at the various stages of obtaining PRP. In this literature review, we take a closer look at eight parameters which may influence the quality of PRP: 1) anticoagulants used to preserve the best platelet function, 2) the speed of centrifugation used to extract the platelets, 3) the platelet concentrations obtained, 4) the impact of the concentration of red and while blood cells on PRP actions, 5) platelet activators encouraging platelet degranulation and, hence, the release of growth factors, and 6) the use or nonuse of local anesthetics when carrying out infiltration. In addition to these parameters, it may be interesting to analyze other variables such as 7) the use of ultrasound guidance during the injection with a view to determining the influence they have on potential recovery.

Aim: The Psychopathy Checklist-Revised (PCL-R) is the most studied and validated instrument to measure psychopathy. We aimed to explore its items content invariance to forensic schizophrenic subjects. Method: We examined the PCL-R protocol of 15 male forensic schizophrenic subjects and attributed a score of sensitivity to psychotic symptomatology to each item score. Results: Results suggest that the applicability of the PCL-R items to a forensic schizophrenic sample is not to be blindly warranted. Some items more systematically positively influenced by psychotic symptoms (e.g. Shallow Affect, Lack of Remorse or Guilt), while others were negatively influenced (e.g. Promiscuous Sexual Behavior, Glib and Superficial Charm), or not influenced at all (e.g. Criminal Versatility). Conclusions: The current study suggest that the applicability of the PCL-R items to a forensic schizophrenic sample is not to be blindly warranted. We discuss both psychometric and conceptual implications for the measurement of psychopathy when a diagnosis of schizophrenia has been established. [less ▲]

This paper offers a reconstruction of Franz Brentano’s mereological solution to the problem of the unity of consciousness and explores some implications of this solution for the ontology of the mind. In section 1 I sketch Brentano’s ontological distinctions between things, collectives, and divisives. In section 2 I present Brentano’s mereological solution and in section 3 I review his main pro-arguments. Eventually, in section 4 I consider some Jamesian objections to the mereological approach. I argue the notion of ‘mental parts’ can be given a rather innocuous meaning by being conceived of as the expression of conceptual distinctions grounded in similarity and contrast relations between total mental phenomena.

Hemicelluloses and Lignin in Biorefineries provides an understanding of lignocellulosic biomass, which is mainly composed of cellulose, hemicelluloses, and lignin. It promotes the valorization of these molecules in the context of the bioeconomy and presents hemicelluloses and lignin, which are generated in lignocellulosic biorefineries, as the molecules of the future. The viability of these molecules lies in their renewability and potential. This book covers all aspects of hemicelluloses and lignin including structure, biosynthesis, extraction, biodegradation, and conversion. The book also looks ahead to the socioeconomic and environmental value of biobased industry and emphasizes an understanding of the potential of lignocellulosic biomass. [less ▲]

The paper describes the factors influencing the interplay of pension and tax policies from a fiscal and welfare perspective, and identifies areas where both topics can materially impact one another. The paper also explores the arguments for coordination between income tax and pension policies in light of the distributional and behavioral synergies. The paper raises questions regarding tax policy’s effectiveness for materially influencing pension coverage, contribution compliance, and labor mobility. The authors argue for taxing pension similarly to all other incomes and for limiting tax treatment of mandatory pensions, and for initiating coordinated tax and pension reforms before electoral demographics render such reforms even more difficult than today.

One of the main consequences of the Roman conquest was the diffusion of the Latin language and of Roman culture throughout the conquered countries. According to many texts of the imperial period, Latin became a universal language during the Imperium Romanum. But what is the reality? Did Rome develop any linguistic policies? There is some evidence to show that Rome’s response regarding the sociolinguistic problems that arose under its rule was to be flexible and willing to adapt to the specific requirements of each situation. Under the Republic and the early Principate, there was, in fact, a great flexibility in language use by the Romans in their dealings with the Greek world. Even though Latin-Greek bilingualism was widespread among the Romans of the Republic and the early Principate, in the public context, Latin maintained a high-level role because it represented the language of Rome’s power. In spite of this flexible approach to language use, a natural competition developed between the language of the dominant and the language of the dominated. In the Occident, Latin became the only vehicle of communication, both oral and written, whereas in the Orient, one notes a paradoxical situation: the Hellenization of the Romans due to the high cultural position of the Greek language. However, this dichotomy did not produce a division of the Roman Empire into two impenetrable parts, closed to mutual linguistic and cultural influences, but rather, it generated a more complicated situation, especially in the Oriental part of the Empire. It is this situation that will be analyzed in the present paper. [less ▲]

This paper reviews the state-of-the-art methods to perform structural optimization of flexible mechanisms. These methods are based on a system-based approach, i.e. the formulation of the design problem incorporates the time response of the mechanism that is obtained from a dynamic simulation of the flexible multibody system. The system-based approach aims at considering as precisely as possible the effects of nonlinear dynamic loading under various operating conditions. Also, the optimization process enhances most existing studies which are limited to (quasi-) static or frequency domain loading conditions. This paper briefly introduces flexible multibody system dynamics and structural optimization techniques. Afterwards, the two main methods, named the weakly and the fully coupled methods, that couple both disciplines are presented in details and the influence of the multibody system formalism is analyzed. The advantages and drawbacks of both methods are discussed and future possible research areas are mentioned. [less ▲]

The unsteady Vortex Lattice method is becoming an increasingly popular aerodynamic modelling method for incompressible aeroelastic problems, such as flexible low-speed aircraft, wind turbines and flapping flight. It leads to discrete time aeroelastic state space equations, which must be solved in a time-marching framework. Eigenvalue or singular value decompositions of the discrete time equations can be used in order to perform stability analysis but such procedures must be accompanied by model order reduction because the size of the equations is large. This work proposes a modal frequency domain implementation of the Vortex Lattice method, resulting in a modal generalised force matrix. Model order reduction is implicit in the modal approach and stability analysis can be carried out using industry-standard flutter analysis techniques, such as the p-k method. The approach is validated by comparison to wind tunnel flutter data obtained from rectangular cantilever flat plate wings of different aspect ratios and sweep angles. It is found that the aeroelastic model predictions follow the experimental trends for both flutter speed and frequency but tend to be moderately conservative. [less ▲]

Normalization of the electromyography (EMG) signal is often performed relatively to maximal voluntary activations (MVA) obtained during maximum isometric voluntary contraction (MVIC). The first aim was to provide an inter-session reproducible protocol to normalize the signal of eight shoulder muscles. The protocol should also lead to a level of activation >90% of MVA for >90% of the volunteers. The second aim was to evaluate the influence of the method used to extract the MVA from the EMG envelope on the normalized EMG signal. Thirteen volunteers performed 12 MVICs twice (one-week interval). Several time constants (100 ms to 2 s) were compared when extracting the MVA from the EMG envelope. The EMG activity was also acquired during an arm elevation. Our results show that a combination of nine MVIC tests was required to meet our requirements including reproducibility. Both the number of MVIC tests and the size of the time constant influence the normalized EMG signal during the dynamic activity (variations up to 15%). A time constant of 1 s was a good compromise to extract the MVA. These findings are valuable to improve the reproducibility of EMG signal normalization. [less ▲]

The Saint-Denis altarpiece has been widely admired, commented and studied for a long time. Its conservation in the church, even after a new main altar in baroque style was placed in the choir, is an indication of the importance this work had acquired throughout time. Its painted wings were especially appreciated and were attributed to Lambert Lombard, Liège’s most renowned Renaissance painter, as early as the beginning of the 18th century. But this attribution has been discussed passionately, especially since the 1970’s. At the centre of these debate, we find a document dated 1533, discovered in 1958, naming a “Lambertum pictorem” working for Saint-Denis collegiate church. But this mention needs to be reconsidered and contextualised. This publication aims to present the content of this document and to dissect its meaning in the context of the making of the altarpiece, to which it has been related since its discovery. A new transcription will be provided and new archival material will be unveiled in order to shed a new light on this document as well as to give new paths to reconstruct the processes at work in the making of the altarpiece.

La démocratie reste un thème chéri par la philosophie politique contemporaine, pour l’écart entre ses théories et ses pratiques, pour la distance critique que ses théories offrent vis-à-vis des régimes démocratiques et de leur évolution, mais aussi parce qu’elle est un objet perpétuel de dissensus entre philosophes, au sujet duquel toute prétention à la véridiction est suspendue à sa réalisation pratique. À ce titre, la transmission de la volonté démocratique est un topos houleux de la philosophie politique contemporaine. Cette question catalyse les concepts pivots des philosophies politiques, la leur poser permet de mieux saisir les enjeux rivaux derrière une terminologie commune à plusieurs auteurs. C’est dans cette démarche que je vous propose d’examiner en miroir les philosophies de Cornélius Castoriadis et de Jacques Rancière. De plus en plus nombreux, des commentateurs rapprochent leurs pensées , qui peuvent s’appuyer sur plusieurs points communs : un attachement au concept de démocratie brandit contre les régimes parlementaires, une opposition contemporaine (quoique depuis des héritages différents) aux thèses défendues par Althusser, et une proximité de sources d’inspirations : la philosophie, le marxisme, et la psychanalyse. Partant de la manière dont cette proximité s’exprime dans la disjonction que chacun opère entre démocratie et science, je tenterai de discerner comment les inflexions qu’ils impriment aux concepts de volonté et d’égalité sous la guise des enjeux de la transmission dessinent des horizons politiques distincts, et dénotent des compréhensions antithétiques – mais indécidables dans la théorie – de ce que peut être la démocratie.

Objectives: (1) To investigate music theory teachers’ professional and extra-professional vocal loading and background noise exposure, (2) to determine the correlation between vocal loading and background noise, and (3) to determine the correlation between vocal loading and self-evaluation data. Methods: Using voice dosimetry, 13 music theory teachers were monitored for one workweek. Parameters analysed were voice SPL, F0, phonation time, vocal loading index (VLI) and noise SPL. Spearman’s correlation was used to correlate vocal loading parameters (voice SPL, F0 and phonation time) and noise SPL. Each day, subjects self-assessed their voice using visual analogue scales. VLI and self-evaluation data were correlated using Spearman’s correlation. Results: Vocal loading parameters and noise SPL were significantly higher in the professional than in the extra-professional environment. Voice SPL, phonation time and females’ F0 correlated positively with noise SPL. VLI correlated with self-assessed voice quality, vocal fatigue and amount of singing and speaking voice produced. Conclusions: Teaching music theory is a profession with high vocal demands. More background noise is associated with increased vocal loading and may indirectly increase the risk for voice disorders. Correlations between VLI and self-assessments suggest that these teachers are well-aware of their vocal demands and feel their effect on voice quality and vocal fatigue. Visual analogue scales seem to represent a useful tool for subjective vocal loading assessment and associated symptoms in these professional voice users. [less ▲]

Flowers are susceptible to many pests and diseases. Therefore, they can be sprayed several times during their growth considering that no MRL are set for flow-ers. High levels of pesticide residues potentially expose daily the florists who han-dle cut flowers and possibly could endanger their health. A study was carried out to evaluate the risk for florists exposed to fungicide residues during normal profes-sional tasks. Cotton gloves were distributed to 20 florists (two pairs to each florist) and worn during two consecutive half days during normal professional tasks (from min 2 hours to max 3 hours/day) to measure their potential dermal exposure (PDE). Samples were analyzed with a multi-residue (QuEChERS) method validated by a laboratory accredited for pesticide residues and with a combination of gas and liquid chromatography tandem mass spectrometry. It appears from the results that a total of 54 fungicides with different toxicity classes were detected on cotton gloves. An average of 15.53 mg/kg fungicide residues per glove sample was meas-ured. Six of 54 are suspected of causing cancer after prolonged or repeated expo-sure. Boscalid was both the active substance for which the highest maximum and average concentrations (26.21 and 3.47 mg/kg, respectively). Famoxadone had the most critical PDE (156% AOEL for the maximum concentration). As a consequence, this study leads to conclude that Belgian florists, who worked for several years and handled a large number of flowers contaminated by high concentrations of pesti-cide residues, are exposed daily with a potential effect on their health. This sug-gests that safety standards should be set for residue levels on cut flowers. [less ▲]

Plant protection products play a very important role in agriculture. However, their misuse can have serious negative impacts both on human health and environment. A study was carried out to identify the plant protection products used in the Niger River valley and to observe the local pesticide management practices. Ten active substances were identified as the most used chemicals by farmers. Their toxicological properties were characterized and their respective Potential Dermal Exposures (PDE) was evaluated in order to assess the risk level for the local small growers. The UK Predictive Operator Exposure Model was used to quantify the PDE during mixing/loading and application according to the local practices. The survey shows that the most common active substances are organophosphate or pyrethroids insecticides. In addition, some other prohibited and counterfeit pesticides cocktails are also used. All active substances used in Niger River valley are highly toxic. When sprayed without personal protective equipment (PPE) they could induce significant harmful impacts on the human health after exposure. The predictive exposure levels vary from 0.0013 mg/kg bw/day to 0.4125 mg/kg bw/day, several times higher the Acceptable Operator Exposure Level (AOEL) for all actives substances. The survey also revealed that 76% of operators do not use any PPE during mixing/loading or spraying. Other bad practices observed in study area can increase the exposure of operators. Moreover, local consumers could also be exposed through intake of pesticide residues on harvested products. [less ▲]
