The authors have investigated the flow properties of powders by using two classical techniques based on the shear stress measurements and the count of intermittent avalanches, respectively. Results are compared with measurements of the compaction dynamics. Strong correlations are evidenced between compaction relaxation parameters and free flow characteristics. Those correlations are given by semiempirical laws based on physical arguments. This work opens perspectives in powder technology and the knowledge on granular matter.

In recent decades, a growing number of studies have addressed connections between ecological and evolutionary concepts in biologic invasions. These connections may be crucial for understanding the processes underlying invaders' success. However, the extent to which scientists have worked on the integration of the ecology and evolution of invasive plants is poorly documented, as few attempts have been made to evaluate these efforts in invasion biology research. Such analysis can facilitate recognize well-documented relationships and identify gaps in our knowledge. In this study, we used a network-based method for visualizing the connections between major aspects of ecology and evolution in the primary research literature. Using the family Poaceae as an example, we show that ecological concepts were more studied and better interconnected than were evolutionary concepts. Several possible connections were not documented at all, representing knowledge gaps between ecology and evolution of invaders. Among knowledge gaps, the concepts of plasticity, gene flow, epigenetics and human influence were particularly under-connected. We discuss five possible research avenues to better understand the relationships between ecology and evolution in the success of Poaceae, and of alien plants in general. [less ▲]

Contact employees play a critical role in creating favorable customer perceptions. We aim to understand to which extent contact employee emotional intelligence relates to customer perceptions of rapport, and their satisfaction and behavioral intentions. We developed a causal model and tested it with PLS. We found that customer perceptions of contact employee emotional intelligence influence their perceptions of rapport. In turn, rapport influences cognitive and emotional satisfaction. Both types of satisfaction lead to behavioral intentions. In order to improve customer perceptions of rapport, managers could focus on contact employees’ emotional intelligence when hiring and training them. [less ▲]

Shipbuilding has been severely affected by the global economic crisis. Demand for new ships has collapsed world wide since summer 2008 causing an unprecedented levels of overcapacity in the global cargo ship fleets. The current crisis gives impulses for a radical think to adopt new designs to reduce the life cycle costs and to decrease the environmental impact. Leading shipping companies recognise that low life cycle cost and low emission save costs, open quality sensitive markets and will be the key driver to profitability in the future. The speaker will present some possible techniques to improve the link between design and production in order to boost the competitiveness of worldwide shipyards. Modularizations, ease of manufacturing, standardization, virtual reality, production simulation, product life cycle management, are some of these techniques illustrated in the presentation. The speaker will also draw the trends for the future years. [less ▲]

As most of sub-Saharan Africa countries, Benin has noted a growth of rural radio stations over the past few decades as part of a broader process of democratisation. This paper examines the level of farmers’ access to rural radio in relation to gender and livelihood assets. The study was conducted in the north and south of Benin with 18 rural radio stations and 240 rice processors selected at random in 12 villages. We used the Sustainable Livelihoods (SL) framework with 120 rice processors randomly selected among the 240 surveyed rice processors. About 67% of the women rice processors had their own radio set compared to 87% of the men. Although the study did not allow to draw conclusions on causal relationships, rice processors who often listened to agricultural broadcasts had better social, financial and human capital stocks compared to those who didn’t listen to agricultural broadcasts. Despite the applaudable efforts of 72% of the radio stations to link up with extension services, half of the rice processors rarely or never listened to agricultural broadcasts, because the timing of the broadcasts was inappropriate. Interactive radio sessions with farmers that involve government officials will need to address this if they are to become more effective. [less ▲]

Poly-cultures are cropping systems using multiple crops in the same space and time, avoiding large stands of sole crops, hence contributing to reconciliation ecology. These land uses have several advantages over monocultures, e.g. increased biodiversity and diversification of agricultural production. Coupled with soil conservation measures, they also contribute to erosion control and resource protection in fragile areas. The viability of such systems often depends on their efficiency under limited resource conditions, which in turn makes them acceptable among the farming community. Most farmers, however, are reluctant to adopt such systems because they may compete for water and nutrients. This study was conducted during 2011 on the Queen Sirikit research farm, Ban Bo Wi village, Ratchaburi province, in North-West Thailand to investigate the competition in maize based soil conservation systems. The soil at the field site ranged from an endoleptic Alisol to ahyper skelletic Leptosol. The treatments were maize under farmer's practice (control) and maize-chili intercropping combined with alley cropping of Leucaena under minimum tillage and Jack bean relay cropping with and without fertiliser application. Plot size was 4 m by 13 m and slope of 18-20%. We used both carbon isotopic discrimination and electrical resistivity tomography (ERT) imaging, a novel non-invasive method, to understand and distinguish the competition for water and nutrients in tropical field conditions. A negative relationship was observed between 13C isotopic discrimination and total nitrogen in grain with R2 ranging from 0.63 (p ≤ 0.01) to 0.70 (p ≤ 0.001) while a positive correlation was found between total nitrogen in grains and total dry matter production with R2 ranging from 0.51 (p ≤ 0.04) to 0.84 (p ≤ 0.001). Nutrient competition induced an increase in δ13C values in maize rows close to Leucaena hedgerows and decreased their total dry matter production. ERT imaging showed different water depletion patterns during the growing season, directly linked with the growth and development of maize such as leaf area index, plant height and canopy cover. This helped explaining the impact of hedgerows on crop growth and yields in maize rows adjacent to the hedges, leading to various spatial patterns along the slope. [less ▲]

Migration issues are often thought and debated in terms of societal security. The association of migration with a series of social ills such as crime, urban disorder, unemployment, etc. in the mass media and in some political statements is common to many countries. In these conditions, the task of social and political scientists is very delicate and complex, as they are asked to produce objective knowledge about a highly politicised set of issues. Could their work not contribute to the over-dramatisation of migration, even though their aim may be exactly the opposite? Is there not a risk for the results of their work to be misinterpreted in order to fit political strategies? [less ▲]

The present study focused on the nature of the reading disability of children with both dyslexia and inhibition deficit. Van der Schoot et al. (2000; 2004); Nossent et al. (2005); Nossent and Deroux (2006) showed that these children tended more to guess the words they read because these “guessers” found difficulties in suppressing false candidate words that are activated in the lexicon. To test this account, dyslexic children with and without inhibition deficit were presented a sentence reading task. To evoke guessing, each sentence contained a word or a pseudoword which closely resembled either a valid congruent or incongruent word. Our hypothesis was that dyslexic children with inhibition deficit guessed more the word they read from the sentence context and the global word form than dyslexic children without inhibition deficit. The results showed that both dyslexics with and without inhibition deficit tended more to guess the words than control children without dyslexia and inhibition difficulties. We discussed these results with the fact that most of children with reading difficulties use the sentence context to compensate for poor reading skills. [less ▲]

Given the present state of our knowledge, the question about the links between Egyptian and Greek medicine is far from being resolved. Some convergences can in fact be detected, but when you study them further, you will find that they reveal a loan, or a simple coincidence, or else a false interpretation of the sources. At the end of the sixth century BC, Pharaonic medicine was outclassed and influenced little by little by Greek medicine. Lastly, the Coptic medical treatises, composed in Egyptian language, but written in Greek characters, combine some Greek and finally Arabic borrowings. [less ▲]

An uncoupling protein was recently discovered in plant mitochondria and demonstrated to function similarly to the uncoupling protein of brown adipose tissue. In this work, green tomato fruit mitochondria were purified on a self-generating Percoll gradient in the presence of 0.5% bovine serum albumin to deplete mitochondria of endogenous free fatty acids. The uncoupling protein activity was induced by the addition of linoleic acid during the resting state, and in the progressively uncoupled state, as well as during phosphorylating respiration in the presence of benzohydroxamic acid, an inhibitor of the alternative oxidase and with succinate (+ rotenone) as oxidizable substrate. Linoleic acid strongly stimulated the resting respiration in fatty acid-depleted mitochondria but had no effect on phosphorylating respiration, suggesting no activity of the uncoupling protein in this respiratory state. Progressive uncoupling of state 4 respiration decreased the stimulation by linoleic acid. The similar respiratory rates in phosphorylating and fully uncoupled respiration in the presence and absence of linoleic acid suggested that a rate-limiting step on the dehydrogenase side of the respiratory chain was responsible for the insensitivity of phosphorylating respiration to linoleic acid. Indeed, the ADP/O ratio determined by ADP/O pulse method was decreased by linoleic acid, indicating that uncoupling protein was active during phosphorylating respiration and was able to divert energy from oxidative phosphorylation. Moreover, the respiration rates appeared to be determined by membrane potential independently of the presence of linoleic acid, indicating that linoleic acid-induced stimulation of respiration is due to a pure protonophoric activity without any direct effect on the electron transport chain.
