Hydrophyte communities in the Tam Giang - Cau Hai lagoon

The Tam Giang - Cau Hai lagoon in Thua Thien-Hue province is the largest lagoon in South East Asia and also one of the places having the largest area of seagrass in Vietnam. The study results from 2009 to 2017 showed that 6 seagrasses species were identified (Halodule uninervis is a newly recorded species, however, Halophila minor is not recorded) and there were 8 freshwater grass species (with the exception of Potamogeton maackianus), with a total area of 2,840 ha. In particular, the area of seagrass has been recovering significantly from 1,000 hectares in 2009 to 2,037 hectares in 2017

Extracting Linked Data from statistic spreadsheets

International audienceFact-checking journalists typically check the accuracy of a claim against some trusted data source. Statistic databases such as those compiled by state agencies are often used as trusted data sources, as they contain valuable, high-quality information. However, their usability is limited when they are shared in a format such as HTML or spreadsheets: this makes it hard to find the most relevant dataset for checking a specific claim, or to quickly extract from a dataset the best answer to a given query. In this work, we provide a conceptual model for the open data comprised in statistics published by INSEE, the national French economic and societal statistics institute. Then, we describe a novel method for extracting RDF Linked Open Data, to populate an instance of this model. We used our method to produce RDF data out of 20k+ Excel spreadsheets, and our validation indicates a 91% rate of successful extraction. Further, we also present a novel algorithm enabling the exploitation of such statistic tables, by (i) identifying the statistic datasets most relevant for a given fact-checking query, and (ii) extracting from each dataset the best specific (precise) query answer it may contain. We have implemented our approach and experimented on the complete corpus of statistics obtained from INSEE, the French national statistic institute. Our experiments and comparisons demonstrate the effectiveness of our proposed method

Mangrove is known as a big carbon sink in coastal areas. It is an important organic carbon source which provides for coastal ecosystems. The assessment of the carbon sequestration potential of mangrove contributes to making a scientific base for mangrove conservation and rehabilitation. In this study, the carbon sequestration of mangrove in the Hai Phong coastal areas was measured at three dominant species of mangrove Rhizophora stylosa Griff; Kandelia obovata Sheue, Liu Yong and Sonneratia caseolaris (L.) Engl. The result of the assessment was described by the net canopy photosynthesis (PN­), above and below ground biomass (AGB and BGB), and organic carbon content in sediment. The result showed that the PN ranged from 31.94 ± 1.59 tC.ha-1.yr-1 to 34.83 ± 1.95 tC.ha-1.yr-1 with the R. stylosa community being highest. Above and below ground biomass C stock ranged from 4.03 ± 0.31 t.ha-1 to 294.43 ± 24.67 t.ha-1 and from 2.38 ± 0.16 t.ha-1 to 114.16 ± 8.9 t.ha-1, respectively. S. caseolaris community had the highest biomass and R. stylosa community had the lowest biomass. The measurements of C stock in mangrove biomass for three species were R. stylosa (2.69 ± 0.19 t.ha-1); K. obovata (6.72 ± 0.34 t.ha-1) and S. caseolaris (171.61 ± 14.1 t.ha-1). The organic carbon content of sedimentscores at 10 cm depth ranged from 685.63 milligram.kg-1 of se. dry to 2676.64 milligram.kg-1 of se. dry and at 40 cm depth ranged from 937.38 milligram.kg-1 of se. dry to 2557.55 milligram.kg-1 of se. dry. The total organic carbon was stored highest in the R. stylosa community.Rừng ngập mặn là một bể chứa cacbon lớn khu vực ven biển, là một nguồn cung cấp cacbon hữu cơ quan trọng cho hệ sinh thái ven biển.

Mixed-instance querying: a lightweight integration architecture for data journalism

International audienceAs the world's affairs get increasingly more digital, timely production and consumption of news require to efficiently and quickly exploit heterogeneous data sources. Discussions with journalists revealed that content management tools currently at their disposal fall very short of expectations. We demonstrate TATOOINE, a lightweight data integration prototype, which allows to quickly set up integration queries across (very) heterogeneous data sources, capitalizing on the many data links (joins) available in this application domain. Our demonstration is based on scenarios we study in collaboration with Le Monde, France's major newspaper

Efficient inference of large prokaryotic pangenomes with PanTA

Pangenome inference is an indispensable step in bacterial genomics, yet its scalability poses a challenge due to the rapid growth of genomic collections. This paper presents PanTA, a software package designed for constructing pangenomes of large bacterial datasets, showing unprecedented efficiency levels multiple times higher than existing tools. PanTA introduces a novel mechanism to construct the pangenome progressively without rebuilding the accumulated collection from scratch. The progressive mode is shown to consume orders of magnitude less computational resources than existing solutions in managing growing datasets. The software is open source and is publicly available at https://github.com/amromics/panta and at 10.6084/m9.figshare.23724705

Treatment recommendation differences for schizophrenia and major depression: a population-based study in a Vietnamese cohort

Background: In Vietnam, the mental health care infrastructure is on the verge of transformation with an increase in the demand for access to adequate and effective mental health care services. Public attitudes towards mental illness, as well as corresponding treatment options influence help-seeking behaviors of patients and caregivers, affecting the course of their treatment. This study assesses attitudes towards treatment options for depression and schizophrenia, as the two most common psychiatric disorders in Vietnam, accounting for at least 75% of all psychiatric inpatients. Methods: A general population-based survey was conducted in Hanoi, Vietnam between April and August 2013. Participants received a description of a person with symptoms of either depression (n=326) or schizophrenia (n=403) and were asked to give recommendations for adequate sources of mental health support and treatment options. Multiple analyses on a single item level compared the likelihood of recommendation between schizophrenia and depression. Results: Overall, respondents recommended health care services, ranging from seeking mental health care professionals, psychotherapists, and psychiatrists for both disorders. Psychotherapy was the most favored treatment method, whereas further treatment options, such as concentration and relaxation exercises, meditation or yoga and psychotropic medication were also endorsed as helpful. For the schizophrenia vignette condition, psychotherapy, visiting a psychiatrist or psychotherapist received stronger endorsement rates as compared to the depression vignette. Furthermore, ECT, Feng Shui-based practices, praying and visiting natural healers were recommended less by respondents for the depression vignette in comparison with the schizophrenia vignette. Conclusions: The Vietnamese public endorsed evidence-based treatment recommendations from a variety of treatments options. Differences in the treatment recommendations between depression and schizophrenia reflected the perceived severity of each disorder. Further developments of the Vietnamese mental health care system concerning mental health care providers, as well as the legal regulations surrounding the provision of psychotherapy are needed

Controlling soil-borne fungus aspergillus niger in groundnut by optimizing the function of isolated bacillus bacteria

Collar rot is a devastating disease caused by the soil-borne pathogen Aspergillus niger that greatly affects groundnut production worldwide. The long-term persistence of the fungus in the soil can reduce the effectiveness of synthetic fungicides. Recently, significant attention has been raised to the use of the biological control method such as the application of antagonistic microorganisms, which potentially decline the number of spores and eradicated A. niger from the soil. In the present study, three Bacillus strains (Bacillus siamensis 101, B. siamensis 112 and B. velezensis 137) isolated from the rhizosphere soil of groundnut cultivation farms were found to inhibit the growth of A. niger mycelia by 53.6% to 60.8% in vitro. In pot experiments, the supplementation of this mixture of three bacterial strains (namely BAZ04) strongly reduced the collar rot symptoms of groundnut with a biocontrol efficacy of 100% compared to nil (no treatment). Field trials demonstrated the efficiency of BAZ04 in controlling collar rot disease, which increased the yield by 20.5–22.7% compared to the untreated plots. These results suggest that BAZ04 is a potential biocontrol agent for collar rot disease

Electron beam and thermal stabilities of MFM-300(M) metal–organic frameworks †

This work reports the thermal and electron beam stabilities of a series of isostructural metal–organic frameworks (MOFs) of type MFM-300(M) (M = Al, Ga, In, Cr). MFM-300(Cr) was most stable under the electron beam, having an unusually high critical electron fluence of 1111 e− Å−2 while the Group 13 element MOFs were found to be less stable. Within Group 13, MFM-300(Al) had the highest critical electron fluence of 330 e− Å−2, compared to 189 e− Å−2 and 147 e− Å−2 for the Ga and In MOFs, respectively. For all four MOFs, electron beam-induced structural degradation was independent of crystal size and was highly anisotropic, although both the length and width of the channels decreased during electron beam irradiation. Notably, MFM-300(Cr) was found to retain crystallinity while shrinking up to 10%. Thermal stability was studied using in situ synchrotron X-ray diffraction at elevated temperature, which revealed critical temperatures for crystal degradation to be 605, 570, 490 and 480 °C for Al, Cr, Ga, and In, respectively. The pore channel diameters contracted by ≈0.5% on desorption of solvent species, but thermal degradation at higher temperatures was isotropic. The observed electron stabilities were found to scale with the relative inertness of the cations and correlate well to the measured lifetime of the materials when used as photocatalysts

Identification of Two Enzymes for Trehalose Synthesis and Their Potential Function in Growth and Development in Peanut (Arachis hypogaea)

Plant trehalose has been regarded to play a key role in various biological processes during the growth and development stages. Trehalose-6-phosphate synthase (TPS) and trehalose-6-phosphate phosphatase (TPP) are two important enzymes for the synthesis of plant trehalose. Up till now, the TPS and TPP gene families have been identified and characterized in numerous higher plant species, but are rarely recorded in peanuts (Arachis hypogaea). In this study, a comprehensive search was performed to identify all putative TPS and TPP proteins in the peanut genome using Arabidopsis TPS and TPP proteins as queries. We then analyzed the characteristics of TPS and TPP members, including physic-chemical parameters, subcellular localization, phylogeny relationships, gene duplication, and expression patterns by various computational tools. As a result, a total of 17 ArahyTPS and 15 ArahyTPP genes were identified and annotated in the peanut genome, which was expanded by segmental duplication events. Our Neighbor-Joining based phylogenetic tree indicated that the ArahyTPS and ArahyTPP proteins could be categorized into three and two major branches. Gene structures and protein features analysis exhibited that the ArahyTPS and ArahyTPP proteins shared high structural and functional similarities. Based on previous RNA-Seq datasets, a majority of the ArahyTPS and ArahyTPP genes were found to specifically express in at least one major organ/tissue during the growth and development. This work will not only lead to a solid foundation on reveal the potential roles of ArahyTPS and ArahyTPP gene families in peanuts but also provide evidence to related trehalose research in other higher plant species

DẪN LIỆU MỚI VỀ MÔI TRƯỜNG NƯỚC VÀ SINH VẬT TRONG CÁC HANG NGẦM VÀ HỒ NƯỚC MẶN KHU VỰC VỊNH HẠ LONG, CÁT BÀ

Submerged caves and saltwater lakes are 2 common habitat types in Ha Long and Cat Ba. However, depending on many different reasons so far they have been poorly studied both on environmental and biological characteristics. The initial results on environment and biological communities in 3 submerged caves (Hang Sang, Hang Toi, Qua Bang) and 3 saltwater lakes (Ang Dau Be, Ang Du, Ang Qua Bang) showed that: status of water environment was different among lakes, especially in the closed lake as Ang Du where salinity was low (9‰), while salinity in the lakes connected to the sea was equal to marine environment (23 - 27‰). Concentration of dissolved oxygen (DO) in saltwater lakes was high from 7.63 - 9.03 mg/L and higher than that in submerged caves and surrounding marine environment. Physical and chemical factors of water in the submerged caves were equivalent to the marine environment because these caves are connected to the sea and water regularly goes in and out according to tidal fluctuation. Organism communities in the submerged caves were abundant with over 142 species being found. The popular groups, sponge and soft coral, were distributed along the length of the caves. Several species with high economic value were commonly observed in the caves, including stone crab Myomenippe hardwickii, flower crab Portunus pelagicus, cone snails Trochus pyramis, shoemaker spinefoot Siganus sutor, snapper Lutjanus russelii ... Species that permanently live in cave were not detected. In the lakes where water is well exchanged to the sea, coral reefs were found and they formed a narrow reef around the lake. Sandy bars often appeared around the lake at the depth of 0.5 - 2 m, containing specialty species as phi (Sanguinolaria diphos), snout otter clam (Lutraria rhynchaena), sea cucumbers with high density (Ang Dau Be, Ang Qua Bang). There was no coral reef in the closed lake (Ang Du) because of low salinity. In this lake, stratification of temperature and salinity led to temperature on surface lower than that on bottom from 30C to 60C, this phenomenon is unusual.Hang ngầm và hồ nước mặn là 2 dạng sinh cảnh khá phổ biến ở Hạ Long và Cát Bà, do nhiều nguyên nhân khác nhau đến nay chúng rất ít được quan tâm nghiên cứu. Các kết quả nghiên cứu bước đầu về môi trường và quần xã sinh vật trong 3 hang ngầm (Hang Sáng, Hang Tối, Hang Quả Bàng) và 3 hồ nước mặn (Áng Đầu Bê, Áng Dù, Áng Quả Bàng) cho thấy: Môi trường nước có sự khác biệt giữa các hồ, đặc biệt là trong hồ kín như Áng Dù có độ muối thấp (9‰), trong khi các hồ có cửa thông với biển có độ muối gần tương đương với môi trường ngoài (23 - 27‰). Hàm lượng chất khí hòa tan như DO trong các hồ nước mặn khá cao từ 7,63 - 9,03 mg/l, cao hơn trong hang ngầm và cao hơn ở môi trường biển xung quanh. Các yếu tố vật lý và hóa học trong môi trường nước tại các hang ngầm gần tương đương với môi trường bên ngoài do có các hang ngầm đều thông với biển và có nước chảy thường xuyên theo sự lên xuống của thủy triều. Quần xã sinh vật trong các hang khá phong phú với trên 142 loài được tìm thấy, phổ biến nhất là hải miên và san hô mềm, chúng phân bố dọc chiều dài hang. Có một số loài có giá trị kinh tế cao thường gặp trong hang là Cù kì Myomenippe hardwickii, ghẹ Portunus pelagicus, ốc nón Trochus pyramis, cá dìa Siganus sutor, cá hồng Lutjanus russellii ... Chưa phát hiện thấy các loài chuyên biệt sống cố định trong hang. Ở các hồ nước lưu thông với môi trường bên ngoài có sự xuất hiện của rạn san hô, chúng tạo thành một dải hẹp bao quanh hồ. Các bãi cát thường xuất hiện quanh hồ ở độ sâu 0,5 - 2 m có các loài đặc sản như phi phi, tu hài, hải sâm với mật độ khá cao (Áng Đầu Bê, Áng Quả Bàng). Trong áng kín không có rạn san hô do nước có độ muối thấp, có sự phân tầng của nhiệt độ và độ muối làm cho nhiệt độ ở tầng mặt thấp hơn tầng đáy 3 - 60C đây là hiện tượng bất thường ở các hồ này
