Aims Soils are rich, diversified environments where β-glucosidases abound because of their importance in organic matter degradation. The aim of this work was to discover new β-glucosidases by constructing two metagenomic DNA libraries from soil samples collected in winter and spring from a field of winter wheat. Methods and Results Both libraries were screened on esculin-supplemented medium so as to isolate candidates showing β-glucosidase activity. Candidate analysis revealed seven putative β-glycosidases and two putative glycosyltransferases, displaying 25 to 82% identity to known enzymes. The putative β-glycosidases belong to families GH1, GH3 and GH20 and the two putative glycosyltransferases, probably, to new families. In characterization tests performed on bacteria in suspension or spread on agar plates, some candidates appeared to hydrolyse several natural and synthetic substrates. These tests also highlighted interesting industrial characteristics, such as the activity of four β-glycosidases under alkaline conditions and the esculin-hydrolysing activity of a β-glucosidase candidate in the presence of glucose. Conclusions Seven putative β-glycosidases and two putative glycosyltransferases were found by functional screening of two metagenomic DNA libraries derived from agricultural soil. Significance and Impact of the Study This study has identified β-glycosidases and putative glycosyltransferases that have or may have interesting industrial characteristics. [less ▲]

The ring-opening polymerization of lactides has been studied in bulk using either 2-ethylhexanoic acid tin(II) salt, Sn(Oct)2, or aluminum triisopropoxide, Al(OiPr)3, as the initiator over a wide range of temperature and monomer-to-initiator molar ratio, A high increase in the bulk polymerization rate has been observed when the initiator was added with an equimolar amount of a Lewis base, such as triphenylphosphine and 4-picoline (C6H7N) added to Sn(Oct)2 and Al(OiPr)3, respectively Melt stable polylactides of high molecular weight and reasonably narrow molecular weight distribution have been accordingly prepared. The use of the Sn(Oct)2. equimolar combination has allowed for reaching an acceptable balance between propagation and depolymerization rates, so that the polymerization is fast enough to be performed through a continuous single-stage process in a twin-screw extruder A global activation mechanism is proposed and discussed by comparison with both investigated initiation systems.

This paper discusses challenges for competition authorities in the 21st century. Those challenges were identified on the basis of a statistical review of the articles published since January 2011 in five major antitrust law journals. The assumption underlying this literature review is that the topics that statistically attract the most the attention from contemporary antitrust scholars are those that will likely constitute the main challenges for 21st century competition authorities.

The supply chain of seafood in Vietnam has not been effectively designed and operated, and has not contributed to the sustainability of the sector. Problems include the protection of resources, limitations in traceability, food safety issues and lack of branding/eco-certification. The objective of this article is first to characterize the recent development of this sector of economic activity. Particular attention will be linked to the importance of aquaculture in the trade balance of Vietnam. The authors also describe the issues that arise in the various constituent links in the aquaculture industry in Vietnam. [less ▲]

The HER2 proto-oncogene product is overexpressed in 30% of breast cancers, and this correlates with poor prognosis. Increased levels of HER2 mRNA in breast cancer cell lines result from increased gene transcription. We report the identification of a new 17-bp-long cis sequence located between positions -506 and -489 from the transcription start site. This sequence is recognized by a trans-activating factor that we tentatively named HER2 transcription factor (HTF). This factor, involved in the increased transcription of the HER2 gene in the BT-474 mammary tumor cells, has a molecular weight of about Mr 50,000. HTF can also bind, but with a lower affinity, to a related cis sequence present in the epidermal growth factor receptor promoter. Interestingly, the HTF binding activity is high in nuclear extracts from several mammary tumor cells overexpressing the HER2 gene. [less ▲]

Background This paper reviews the classical and some particular factors contributing to earthquake-triggered landslide activity. This analysis should help predict more accurately landslide event sizes, both in terms of potential numbers and affected area. It also highlights that some occurrences, especially those very far from the hypocentre/activated fault, cannot be predicted by state-of-the-art methods. Particular attention will be paid to the effects of deep focal earthquakes in Central Asia and to other extremely distant landslide activations in other regions of the world (e.g. Saguenay earthquake 1988, Canada). Results The classification of seismically induced landslides and the related ‘event sizes’ is based on five main factors: ‘Intensity’, ‘Fault factor’, ‘Topographic energy’, ‘Climatic background conditions’, ‘Lithological factor’. Most of these data were extracted from papers, but topographic inputs were checked by analyzing the affected region in Google Earth. The combination and relative weight of the factors was tested through comparison with well documented events and complemented by our studies of earthquake-triggered landslides in Central Asia. The highest relative weight (6) was attributed to the ‘Fault factor’; the other factors all received a smaller relative weight (2–4). The high weight of the ‘Fault factor’ (based on the location in/outside the mountain range, the fault type and length) is strongly constrained by the importance of the Wenchuan earthquake that, for example, triggered far more landslides in 2008 than the Nepal earthquake in 2015: the main difference is that the fault activated by the Wenchuan earthquake created an extensive surface rupture within the Longmenshan Range marked by a very high topographic energy while the one activated by the Nepal earthquake ruptured the surface in the frontal part of the Himalayas where the slopes are less steep and high. Finally, the calibrated factor combination was applied to almost 100 other earthquake events for which some landslide information was available. This comparison revealed the ability of the classification to provide a reasonable estimate of the number of triggered landslides and of the size of the affected area. According to this prediction, the most severe earthquake-triggered landslide event of the last one hundred years would actually be the Wenchuan earthquake in 2008 followed by the 1950 Assam earthquake in India – considering that the dominating role of the Wenchuan earthquake data (including the availability of a complete landslide inventory) for the weighting of the factors strongly influences and may even bias this result. The strongest landslide impacts on human life in recent history were caused by the Haiyuan-Gansu earthquake in 1920 – ranked as third most severe event according to our classification: its size is due to a combination of high shaking intensity, an important ‘Fault factor’ and the extreme susceptibility of the regional loess cover to slope failure, while the surface morphology of the affected area is much smoother than the one affected by the Wenchuan 2008 or the Nepal 2015 earthquakes. Conclusions The main goal of the classification of earthquake-triggered landslide events is to help improve total seismic hazard assessment over short and longer terms. Considering the general performance of the classification-prediction, it can be seen that the prediction either fits or overestimates the known/observed number of triggered landslides for a series of earthquakes, while it often underestimates the size of the affected area. For several events (especially the older ones), the overestimation of the number of landslides can be partly explained by the incompleteness of the published catalogues. The underestimation of the extension of the area, however, is real – as some particularities cannot be taken into account by such a general approach: notably, we used the same seismic intensity attenuation for all events, while attenuation laws are dependent on regional tectonic and geological conditions. In this regard, it is likely that the far-distant triggering of landslides, e.g., by the 1988 Saguenay earthquake (and the related extreme extension of affected area) is due to a very low attenuation of seismic energy within the North American plate. Far-distant triggering of landslides in Central Asia can be explained by the susceptibility of slopes covered by thick soft soils to failure under the effect of low-frequency shaking induced by distant earthquakes, especially by the deep focal earthquakes in the Pamir – Hindukush seismic region. Such deep focal and high magnitude (> > 7) earthquakes are also found in Europe, first of all in the Vrancea region (Romania). For this area as well as for the South Tien Shan we computed possible landslide event sizes related to some future earthquake scenarios. [less ▲]
