В статье представлена оценка состояния узкого лаосско-вьетнамского эндемика – сосны повислой (Pinus cernua), основанная как на изучении опубликованной ранее информации, так и на анализе данных, полученных в ходе детальных полевых исследований в сентябре–октябре 2016 г., организованных при поддержке природоохранного фонда Мохаммеда бин Зайеда, Ботанического института им. В. Л. Комарова РАН, Российского фонда фундаментальных исследований (РФФИ) и Центра охраны природы Вьетнамского Союза научно-технических ассоциаций. Выявлено 23 местонахождения вида в горах Фа Луонг, располагающихся на государственной границе Лаоса (провинция Хоуфан) и Вьетнама (провинция Сон Ла), 6 из которых обнаружены впервые. В одном ранее установленном местообитании отмечено полное вымирание вида. Область распространения вида (EOO в определении IUCNRedListCategoriesandCriteria) сократилась за последние 3–5 лет на 25–30 % с приблизительно 20 до 15 км2 при общей площади заселения (AOO в определении IUCN), составляющей на настоящий момент менее 3 км2. На основании этого P. cernua определяется как вид, находящийся под угрозой полного вымирания – CR (Critically Endangered): B1a, b (i-v) и B2a, b (i-v), в соответствии с терминологией и критериями, принятыми Международным Союзом охраны природы (IUCNRedListCategoriesandCriteria). В работе приводятся общие сведения о географии, геоморфологии, климате и растительности гор Фа Луонг, а также детальное описание экологии, мест обитания, биологии, популяционной структуры и таксономии P. cernua. Все данные, полученные в ходе полевых работ, подтверждаются гербарными материалами, которые относятся к 99 семействам, 180 родам и 550 видам, среди которых 6 видов – новые для флоры Вьетнама и Лаоса, 30 видов являются узкими эндемиками, заслуживающими специальной охраны, и 12 – новыми для науки. Определены основные факторы современного вымирания сосны повислой и предложены рекомендации по ее эффективной охране., The paper presents results of completed conservation assessment of the strict Laos-Vietnamese endemic, Pinus cernua, based on survey of all previous publications and data obtained from extensive fieldworks during September–October 2016, supported by Mohamed bin Zayed Species Conservation Fund, Komarov Botanical Institute of the Russian Academy of Sciences, Russian Foundation for Fundamental Investigations (RFFI) and the Center for Plant Conservation of the Vietnam Union of Science and Technology Associations. Present review verified 23 locations of the species in Pha Luong Mountains situated on the state boundary of Laos (Houaphan province) and Vietnam (Son La province). Among available localities, 6 were found at first, the species extinction was detected in 1 locality. The area of the species distribution (EOO) decreased during last 3–5 years on 25–30 % from about 20 to 15 km2, with total occupancy area (AOO) becoming less than 3 km2, therefore species conservation status is assessed as globally critically endangered (CR) following to accepted IUCN Red List Categories and Criteria: B1a, b (i-v), B2a, b (i-v). Report also provides basic data on geography, geomorphology and climate of Pha Luong Mountains, as well as detailed descriptions of P. cernua ecology, habitats, vegetation, biology, population structure and taxonomy. All field data and descriptions are based on collected voucher herbaria, which belong to 99 families, 180 genera and 550 species. Among collected plants, 6 species are new for the flora of Laos and Vietnam, 30 species are local threatened endemics needed protection and 12 species are new for science. The main factors of P. cernua extinction are formulated and the recommendations for its effective protection are proposed.

SSCI-VIDE+ECI2D+JPU:DLA:CGE; International audience; The valorization of lignin coming from pulp industry or biorefinery into renewable chemicals is a great challenge to answer to environmental concerns and carbon atom economy. We present here a new reactor system consisting in a semi-opened batch reactor on the gas-phase to carry out the catalytic lignin liquefaction. The interest of this home-build equipment is that light products and water can be continuously removed from the reacting mixture via gaseous phase circulation whereas the hydrogen donor solvent is reintroduced in the reactor via a reflux system. The catalysts tested are among metal sulfides and metals supported systems and thanks to developed analytic tools (-GC, GCxGC, GPC, NMR), the components of the gas and liquid phases were identified and quantified. Those experiments allow us to determine which type of catalyst would be the best candidate to produce aromatics. In addition, for a given catalyst, experimental data will be used to further propose a kinetic model.

The traditional use of bamboo throughout South East Asia is very diverse: fences, scaffolding, kitchen equipment, furniture, mats, blinds, toothpicks, paper pulp… Some applications use bamboo cane as such, however the current tendency is also towards an unstructured use of bamboo in the form of fibers or chips or even ashes. From strips, a wide variety of boards and plywood are made. Panels from bamboo fibers compressed in the presence of an organic resin are also in development for earthquake-resistant structures of the building market. But in most cases, the bamboo is used for its structural properties, of bamboo cane itself or of particles or fibers from bamboo. Some works only focus on moisture absorption but they mainly concern the bamboo charcoal. Works on thermal insulation bamboo fibers are still rarer. This study focuses on the development and characterization of particle boards which will have the specificity to participate both in thermal insulation and control of humidity inside the building. The advantage is to obtain materials with low environmental impact and to reduce energy consumption due to the reduction of the moisture content. First of all, the conditions for producing fiberboards are studied to obtain panels without glue or using environmentally friendly adhesives. These panels are then characterized according to the criteria required for panels used in buildings (bending, swelling). Finally, their ability to absorb and desorb moisture and their thermal conductivity are investigated., Academic Journal of Civil Engineering, Vol 33 No 2 (2015): Special Issue - ICBBM 2015

A total of 221 isolates of M. tuberculosis were sampled from hospitals and the general population in the northern plain of Vietnam, one of the most populated region of the country. Genotypic composition and diversity were characterized, and we investigated how they are affected by sampling (hospital vs. general population), correcting for potential confounding effects (location, age and gender of the patients). Spoligotyping and 12 MIRU-VNTR typing were used as first line. Then 15 MIRU-VNTR standard set was used, making 21 MIRU-VNTR typing for the clustered isolates. Result showed that 8 lineages and 13 sub-lineages were circulating in the region. The most predominant lineages were Beijing (38.5%) and EAI (38.5%). Others appeared with small proportions H (1.4%), LAM (1.8%), T (8.1%), X (0.9%), MANU (2.3%), and Zero (0.4%). Higher clustering rate was found in the hospital samples (17.9% in urban and 19.2% in rural areas) compared to the population ones (0%). The typical Vietnamese EAI4-VNM sub-lineage of EAI lineage accounted for 67% of EAI strains and was associated with older ages. Beijing genotypes were associated with younger, urban population and were characterized by high clustering rates. These characteristics strongly suggest that Beijing strains are invading the population, replacing the local EAI-VNM4, thus predicting a more serious tuberculosis situation in the future in the absence of more effective control strategies.
