Environment and excavation: Pre-lab impacts on ancient DNA analyses

2008

Ancient DNA (aDNA) analyses enjoy an increasing role in palaeontological, archaeological and archaeozoological research. The limiting factor for aDNA studies is the degree of DNA preservation. Our study on 291 prehistoric cattle remains from Europe, the Near East and North Africa revealed that DNA preservation is mainly influenced by geographic and climatic conditions. Especially in hot climates, the preservation of sample material is generally low. We observed that these specimens are prone to further degradation and contamination during and after excavation. We give a description of the main caveats and a short guideline for adequate sample handling in order to facilitate the cooperation …

Self treating in the moderne era

2013

In the modern era, self healing is to respond to situations created by medicine. Its effectiveness, its limits, its interventions, its practice, its tendency to medicalize existences, its inclusion in market economy are as many factors that interact with the self healing ability as attest the disruption of the patient's identity schema during interventions to repair physical trauma, chronic patient which depends on medicine, the medicalization of the aging. As well the task assigned to the modern man is to escape from enslavements, weathering effects, interferences generated by medical activities. In this sense, self healing is, on the one hand, to decrypt the aims of medicine and to determ…

Chemical properties and oxidative stability of Arjan ( Amygdalus reuteri ) kernel oil as emerging edible oil

2017

The oxidative stability, as well as the chemical composition of Amygdalus reuteri kernel oil (ARKO), were evaluated and compared to those of Amygdalus scoparia kernel oil (ASKO) and extra virgin olive oil (EVOO) during and after holding in the oven (170 °C for 8 h). The oxidative stability analysis was carried out by measuring the changes in conjugated dienes, carbonyl and acid values as well as oil/oxidative stability index and their correlation with the antioxidant compounds (tocopherol, polyphenols, and sterol compounds). The oleic acid was determined as the predominant fatty acid of ARKO (65.5%). Calculated oxidizability value and an iodine value of ARKO, ASKO and EVOO were reported as …

Effect of Calcifediol on Physical Performance and Muscle Strength Parameters: A Systematic Review and Meta-Analysis

2022

There is general agreement that optimal vitamin D status is necessary for bones, muscles, and general health, particularly in older adults, who are at higher risk of negative consequences of vitamin D deficiency, including sarcopenia; vitamin D supplementation is proposed as a potential intervention to mitigate sarcopenia. Several RCTs have reported that calcifediol (25(OH)D) was more potent than cholecalciferol in increasing plasma 25(OH)D. The present systematic review and meta-analysis aimed to summarize the effects of calcifediol on physical performance and muscle strength. We searched databases from inception to 1 January 2022 for studies investigating calcifediol on physical performan…

Reconfiguration: a key to handle exceptions and performance deteriorations in manufacturing operations

2005

During a manufacturing operation, exceptions may occur dynamically and unpredictably. Their occurrence may lead to the degradation of system performance or, in the worst case scenario may interrupt the production process by causing errors in the schedule plan. This paper classifies three families of exceptions: (1) out-of-order events such as machine breakdowns, (2) operational out-of-ordinary events such as rush orders and (3) deteriorations of manufacturing resource performance such as reductions of machines' utilization. In all cases, in order to maintain an adequate level of system performance, it is necessary to detect exceptions, to diagnose them quickly and to recover them by taking …

Call Admission Control in Single and Two-Tier Cellular Networks

2010

We consider four strategies for call admission control (CAC) in single and two-tier cellular networks, which are designed to ensure advantage of handover calls: dynamic redundancy (cutoff priority scheme), partial dynamic redundancy (fractional guard channel scheme), static redundancy (rigid division-based CAC scheme) and restriction of the number of new calls admitted (new call bounding scheme). We show the advantage of dynamic reservation by numerical analysis. We strictly prove it in the case of two-channel system with losses.

L’écriture et le graphisme à l’ère de la linguistique psychologique

2016

This study deals with the conception of “writing” within the German humanities during the « psychological turn » of the last half of the XIXth - the beginning of the XXth centuries. The focal point is “graphism” and “writing” understood as “expressive movements” (Ausdrucksbewegungen), this notion being bound to the concept of “verbal gesture” within the trend of “psychological linguistics” (1850-1930). Inspired initially by the morphological and physiognomonic tradition (J. Lavater, J. W. Goethe, J. Engel, C. Carus, Th. Piderit), this conception considers language as a particular kind of “expressive movements”. This vision comes back to the German psychology of consciousness elaborated by J…

An experimental investigation of claimed self-handicapping strategies across motivational climates based on achievement goal and self-determination t…

2020

The purpose of the present experiment was to investigate whether the motivational climates (MCs) drawn from achievement goal and self-determination theories would affect perceived competence and the use of claimed self-handicapping. Specifically, this study examined the effects of performance MC, mastery MC and need-supportive MC on these two variables. In the context of high school physical education, 37 participants had the opportunity to claim handicaps before performing an isometric resistance task in a given MC. This procedure was repeated three times at one-week intervals so that all participants were assigned to each of the three MCs. Consistent with our hypotheses, students claimed …

Rehabilitative interventions for ischaemic digital ulcers, pain, and hand functioning in systemic sclerosis: a prospective before-after study

2022

Abstract Background Systemic sclerosis (SSc) is a rare connective tissue disease characterised by immune dysfunction, vasculopathy, cellular inflammation, fibrosis of the skin associated with multiple internal organs involvement. Ischaemic digital ulcers (IDU) of the hands commonly occur in patients with SSc adversely affecting functional independence. Purpose Aim of the study is to investigate the effectiveness of a rehabilitation protocol based on the combined use of ultrasound (US) therapy and therapeutic exercise in terms of ulcers healing, pain relief, and hand functioning in patients affected by SSc with IDUs. Moreover, we also investigated the safety of the proposed intervention. Stu…
