description: We suggest that the main outcome of energy leakage carried by waves from the core to the envelope of pre-collapse massive stars is envelope expansion rather than major mass ejection. We show that the propagating waves add to the pressure in the envelope at radii smaller than the radius where the convection driven by the waves becomes supersonic, the driven radius. The extra wave pressure and wave energy dissipation lead to envelope expansion. Using the numerical code MESA we show that the envelope expansion absorbs most of the energy carried by the waves. A possible conclusion from our results is that pre-explosion outbursts (PEOs) result from a binary companion accreting mass from the extended envelope and releasing a huge amount of energy. The accreting companion is likely to expel mass in a bipolar morphology, e.g., jets and an equatorial ring.

description: Nanoparticles (NPs) are a wide class of materials currently used in several industrial and biomedical applications. Due to their small size (1-100 nm), NPs can easily enter the human body, inducing tissue damage. NP toxicity depends on physical and chemical NP properties (e.g., size, charge and surface area) in ways and magnitudes that are still unknown. We assess the average as well as the individual importance of NP atomic descriptors, along with chemical properties and experimental conditions, in determining cytotoxicity endpoints for several nanomaterials. We employ a multicenter cytotoxicity nanomaterial database (12 different materials with first and second dimensions ranging between 2.70 and 81.2 nm and between 4.10 and 4048 nm, respectively). We develop a regressor model based on extreme gradient boosting with hyperparameter optimization. We employ Shapley additive explanations to obtain good cytotoxicity prediction performance. Model performances are quantified as statistically significant Spearman correlations between the true and predicted values, ranging from 0.5 to 0.7. Our results show that i) size in situ and surface areas larger than 200 nm and 50 m2/g, respectively, ii) primary particles smaller than 20 nm; iii) irregular (i.e., not spherical) shapes and iv) positive Z-potentials contribute the most to the prediction of NP cytotoxicity, especially if lactate dehydrogenase (LDH) assays are employed for short experimental times. These results were moderately stable across toxicity endpoints, although some degree of variability emerged across dose quantification methods, confirming the complexity of nano-bio interactions and the need for large, systematic experimental characterization to reach a safer-by-design approach.

description: Boson-sampling is a simplified model for quantum computing that may hold the key to implementing the first ever post-classical quantum computer. Boson-sampling is a non-universal quantum computer that is significantly more straightforward to build than any universal quantum computer proposed so far. We begin this chapter by motivating boson-sampling and discussing the history of linear optics quantum computing. We then summarize the boson-sampling formalism, discuss what a sampling problem is, explain why boson-sampling is easier than linear optics quantum computing, and discuss the Extended Church-Turing thesis. Next, sampling with other classes of quantum optical states is analyzed. Finally, we discuss the feasibility of building a boson-sampling device using existing technology.

description: The aim of this systematic review was to identify and critically appraise the available evidence regarding solid oral dosage forms (SODFs), e.g., tablets, and challenges regarding the oral administration of medicine to inpatients in a variety of healthcare settings such as (1) hospitals, (2) nursing homes and (3) long-term stay units (LTSUs). A literature search was undertaken in September 2021 and repeated in June 2023 in the following databases: PubMed, EMBASE, CINAHL, Scopus, Web of Science, The Cochrane Library, PsycINFO and ProQuest. A Microsoft Excel® spreadsheet was devised to collate the following data from each eligible study: study author and year, country, number of participants, title, duration (follow-up period), study design, inclusion and exclusion criteria, method and data collection, relevant outcomes, and key findings. A total of 3023 records were identified, with 12 articles being included in the final systematic review. Seven of the twelve studies reported on the prevalence of difficulties swallowing SODFs, which varied from 10–34.2%. Nine of the twelve studies reported the methods used to manipulate SODFs, with the most reported method being tablet crushing. Given the prevalence of swallowing difficulties and the subsequent crushing of medicines in response to this, it is evident that concerns should be raised regarding the potential for a medication administration error to occur.

description: Animal and human remains were unearthed in 75 features at Balatonőszöd-Temetői dűlő, among them intramural burials and sacrificial pits. It became clear during the analysis that there was a spatial and chronological overlapping between the seemingly separate Boleráz and Baden settlement centres between 3300 and 3100 BC, which was true for the fi nd materials as well. Features with ceremonial paraphernalia, such as vessels came from the surroundings of the pits with animal and human skeletons and they together formed ritual areas of a ceremonial sequence composed of a series of rites.

description: For the purpose of sulphide removal in aquaculture ponds, three strains (name: TH21, QN71, QN51) were isolated and selected with the highest sulphide removal activity from Thanh Hoa and Quang Ninh coastal zones. These strains have identified and tested in a number of aquaculture ponds in different areas with good water quality results. With the objective of purple non sulfur bacteria biomass production containing 3 selected strains for wide application and suitable price for farmers, in this study, we study on optimum conditions of mixed purple non sulfur bacteria biomass production at pilot scale. The results showed that the sources of substrates were soybean meal (1g/l) and acetate (0.5g/l). These substrates are low cost, easy to find, convenient in large culture. The mixture of photosynthetic bacteria can be cultured in glass tanks, under micro aerobic and natural lighting conditions that produce highly concentrated photosynthetic bacteria and lowest rest media. Nhằm mục tiêu xử lý sulphide trong môi trường nuôi trồng thủy sản, chúng tôi đã phân lập và lựa chọn được ba chủng vi khuẩn tía quang hợp có khả năng loại bỏ sulphide cao nhất ký hiệu TH21, QN71, QN52 từ các vùng ven biển Thanh Hóa và Quảng Ninh. Các chủng này đã được định loại và thử nghiệm tại một số ao nuôi thủy sản ở các vùng khác nhau thu được kết quả tốt về chất lượng nước. Để tạo chế phẩm vi khuẩn tía quang hợp từ 3 chủng lựa chọn được ứng dụng rộng rãi và có giá thành phù hợp cho nông hộ, trong nghiên cứu này, chúng tôi nghiên cứu tối ưu hóa các điều kiện sản xuất sinh khối hỗn hợp 3 chủng vi khuẩn tía quang hợp ở quy mô pilot. Kết quả cho thấy đã tìm kiếm được nguồn cơ chất là bột đậu tương (1g/l) và acetate (0.5g/l) là những chất có giá thành thấp, dễ tìm kiếm, thuận tiện trong nhân nuôi ở quy mô lớn. Hỗn hợp vi khuẩn tía quang hợp có thể nuôi trong các bể kính, ở điều kiện vi hiếu khí, có ánh sáng chiếu tự nhiên có thể sản xuất được chế phẩm vi khuẩn tía quang hợp có mật độ cao, cơ chất còn lại sau sản xuất là ít nhất.

description: INCEFA-SCALE is a five-year project supported by the European Commission HORIZON 2020 programme. It is the successor to the INCEFA-PLUS programme that ran from 2015 to 2020. INCEFA-SCALE kicked off in September 2020. The objective is to advance the ability to predict lifetimes of Nuclear Plant components when subjected to Environmental Assisted Fatigue (EAF) loading. It has been generally observed by nuclear plant operators that there appears to be a disconnect between the perceived difficulty of providing an acceptable assessment result with the current EAF methodologies and the good service experience with regard to this specific degradation mechanism. It is internationally recognised that a possible contributor to this discrepancy is the transferability of laboratory-scale tests to real nuclear components. This is the key knowledge gap addressed by INCEFA-SCALE. To address this gap, the project has identified specific loading, geometric and environmental conditions which are not fully understood and may be considered excessively pessimistically in assessment. The conditions include variable amplitude and multiaxial loading, stress raising features such as notches, and the transferability of results between air and PWR environments, and between specimens with differing surface finishes, under the complex loading scenarios under consideration. Test matrices have been designed to deepen the understanding of specific materials’ (stainless steels) fatigue performance under these conditions, and the testing is well underway at the time of writing. This paper will give an overview of the INCEFA-SCALE testing carried out to date, from the first two one-year phases of the testing programme. The testing and associated analysis has been designed to better understand the material behaviour at the component scale, and assess the applicability of models, developed elsewhere in the project, to predict the lives of these components, which are in turn informed by comprehensive characterisation of the material after failure. The test results are presented in a manner to allow comparison between the experimental fatigue lives and those predicted with standardised assessment procedures, such as NUREG/CR-6909, with comment on how more advanced models (addressed in a different paper), could be used to improve predictions.

description: This study aims to investigate the potential effects of environmental variables and the toxicity of nanosilver colloids synthesized by chemical reduction method on growth and development of phytoplankton community (the Microcystis genus dominance) in the eutrophication Tien lake water, Hanoi city, Vietnam. The variables analyzed including: physical (pH and Turbidity), chemical (content of NH4+, PO43- and silver metal), biological (content of Chlorophyll-a, cell density). The characteristic of nanomaterial was confirmed by using UV-visible spectrophotometer, TEM and HR-TEM methods. The obtained silver nanoparticles (AgNPs) showed that their spherical form and uniform size varied from 10 to 15 nm. The experimental results showed that the samples treated with AgNPs inhibition on growth against M. aeruginosa at concentration 1 mg/l after 8 days. The content of silver in aquarium water decreased from 1 mg/l (D0) to 0.8 mg/l (D8). The contents of chlorophyll-a of phytoplankton community, including Microcystis genus in samples exposed with AgNPs were declined from 11.27 ± 0.56g/L (D0) to 1.98 ± 0.37 g/L (D8) . The environmental variables such as: pH, temperature, dissolved oxygen, turbidity, ammonium, phosphate... in the experiment were below the limit of the Vietnam Standard 08:2015/MONRE for surface water quality. Mục đích của nghiên cứu này là khảo sát ảnh hưởng của vật liệu nano bạc tổng hợp bằng phương pháp khử hóa học đến sinh trưởng và phát triển của quần xã thực vật nổi (chủ yếu là chi Microcystis) trong nước hồ Tiền phú dưỡng, tại Hà Nội, Việt Nam. Các thông số phân tích bao gồm: thủy lý (pH và độ đục), hóa học (hàm lượng amoni, photphat và hàm lượng bạc kim loại), sinh học (hàm lượng chất diệp lục, mật độ tế bào). Đặc trưng của vật liệu được xác định bằng các phương pháp quang phổ UV-VIS, TEM và HR-TEM. Vật liệu nano bạc có dạng hình cầu, kích thước đồng nhất trong khoảng 10-15nm. Kết quả thử nghiệm sau 8 ngày cho thấy các mẫu có bổ sung vật liệu nano bạc ức chế sinh trưởng đối với vi khuẩn lam M. aeruginosa ở nồng độ 1mg/l. Hàm lượng bạc kim loại giảm từ 1 mg/l (ngày đầu tiên) xuống còn 0.8 mg/l (vào ngày cuối cùng).

Insights on the dynamical history of the Fomalhaut system - Investigating the Fom c hypothesis

description: The eccentric shape of the debris disk observed around Fomalhaut was first attributed to Fom b, a companion detected near the belt inner-edge, but new constraints on its orbit revealed that it is belt-crossing, highly eccentric $(e \sim 0.6-0.9)$, and can hardly account for the shape of the belt. The best scenario to explain this paradox is that there is another massive body in this system, Fom c, which drives the debris disk shape. The resulting planetary system is highly unstable, which hints at a dynamical scenario involving a recent scattering of Fom b on its current orbit, potentially with the putative Fom c. Our goal is to give insights on the probability for Fom b to have been set on its highly eccentric orbit by a close-encounter with the putative Fom c. We aim to study in particular the part played by mean-motion resonances with Fom c, which could have brought Fom b sufficiently close to Fom c for it to be scattered on its current orbit, but also delay this scattering event. Using N-body simulations, we found that the generation of orbits similar to that of Fom b, either in term of dimensions or orientation, is a robust process involving a scattering event and a further secular evolution of inner material with an eccentric massive body such as the putative Fom c. We found in particular that mean-motion resonances can delay scattering events, and thus the production of Fom b-like orbits, on timescales comparable to the age of the system, thus explaining the witnessing of an unstable configuration. We conclude that Fom b probably originated from an inner resonance with Fom c, which is at least Neptune-Saturn size, and was set on its current orbit by a scattering event with Fom c. Since Fom b could not have formed from material in resonance, our scenario also hints at former migration processes in this planetary system.

We determine the parameters of the Lagrangian at zero temperature in a hybrid approach, where we treat the mesons at tree-level, while the constituent quarks at 1-loop level. We assume two nonzero scalar condensates and together with the Polyakov-loop variables we determine their temperature dependence according to the 1-loop level field equations.

description: We consider a two-component pancake-shaped, i.e., effectively two-dimensional (2D), Bose-Einstein condensate (BEC) coupled by the spin-orbit (SO) and Rabi terms. The SO coupling adopted here is of the mixed Rashba-Dresselhaus type. For this configuration, we derive a system of two 2D nonpolynomial Schrödinger equations (NPSEs), for both attractive and repulsive interatomic interactions. In the low- and high-density limits, the system amounts to previously known models, namely, the usual 2D Gross-Pitaevskii equation, or the Schrödinger equation with the nonlinearity of power 7/3. We present simple approximate localized solutions, obtained by treating the SO and Rabi terms as perturbations. Localized solutions of the full NPSE system are obtained in a numerical form. Remarkably, in the case of the attractive nonlinearity acting in free space (i.e., without any 2D trapping potential), we find parameter regions where the SO and Rabi couplings make 2D fundamental solitons dynamically stable.

description: Wastewater, especially non-treated wastewater from different sources is one of causes for surface and ground water pollution. However, the monitoring of wastewater quality has not been regularly implemented. This paper presents the preliminary observation results of the wastewater quality of different sources such as domestic, fishery processing, husbandry, agricultural runoff and irrigation canals in some coastal communes of Giao Thuy district, Nam Dinh province in 2017 - 2018. The results showed variation values of some variables as following: pH: 3.4 to 8.7; DO: 1.1 – 7.6 mg/l; conductivity: 0.01 – > 99.9 S/m; Suspended solids: 7 – 599 mg.L-1; nitrate (NO3-): 0.01-1.74 mgL-1; ammonium (NH4+): 0.01 - 3.99 mgNL-1, phosphate (PO43-): < 0.01– 3.05 mgPL-1, total phosphorus: 0.01 – 5.03 mgPL-1. The values of some variables such as DO, pH, nitrite, ammonium, suspended solids and phosphate at some observation time exceeded the allowed values of the Vietnamese standards for domestic wastewater quality, for industrial wastewater quality and for surface water quality. Among these different wastewaters observed, the higher contents of nutrients were found for domestic wastewater. The results provide a dataset for environmental managers in order to control of wastewater quality, especially for the coastal communes where coastal aquacultural areas are large like Giao Thuy district, Nam Dinh province. Nước thải, đặc biệt là nước thải chưa qua xử lý từ nhiều nguồn thải khác nhau là một trong những nguyên nhân gây ô nhiễm nguồn nước mặt và nước ngầm.

Kết quả khảo sát cho thấy khoảng giá trị của một số thông số như sau: pH 3,4 – 8,7; DO: 1,1 – 7,6 mgL-1; độ dẫn điện: 0,01 – 99,9 S/m; chất rắn lơ lửng: 7 – 599 mg.L-1; nitrat (NO3-): 0.01-1.74 mgL-1; amoni (NH4+): 0.01 - 3.99 mgNL-1; phốtphat (PO43-): <0,01 - 3,05 mgPL-1 và phốtpho tổng số: 0,01 – 5,03 mgL-1. Hàm lượng một số chỉ tiêu như NO2, NH4+, PO43-, SS tại một số thời điểm đã vượt quá giá trị cho phép theo các quy chuẩn nước thải sinh hoạt, nước thải công nghiệp và nước tưới tiêu. Trong các loại nước thải đã quan trắc, nước thải sinh hoạt có hàm lượng các chỉ tiêu dinh dưỡng cao hơn. Các kết quả nghiên cứu nhằm cung cấp cơ sở dữ liệu cho các nhà quản lý về việc kiểm soát chất lượng nước thải, đặc biệt là các xã ven biển có diện tích nuôi trồng thủy sản khá lớn như huyện Giao Thủy, tỉnh Nam Định.

description: Presented at the GHRSST XXIII international science team meeting, 27 June-1 July 2022, online and in-person (Barcelona). #GHRSST23 Short abstract As one of the key payloads on the Chinese HaiYang (HY)-1C and HY-1D satellites, the Chinese ocean colour and temperature scanner (COCTS) was designed for global sea surface temperature (SST) and ocean colour detection. Global sea surface temperatures (SSTs) have been detecting by the COCTS instruments since September 2018. The SSTs derived from the COCTS on the HY-1C (COCTS/HY-1C) and HY-1D satellites (COCTS/HY-1D) and the nonlinear SST algorithm with corresponding coefficients will be introduced. The retrieval SSTs from Jan. 1, 2019 to Mar. 31, 2020 were evaluated by the in situ measurements from iQuam with root mean square errors (RMSEs) of 0.84 °C for daytime and 0.97 °C for nighttime and robust standard deviations (RSDs) of 0.73 °C for daytime and 0.72 °C for nighttime, respectively. RMSEs of 0.65 °C and 0.71 °C and RSDs of 0.51 °C and 0.47 °C were obtained for the daytime and nighttime SSTs of the COCTS/HY-1D recorded from April 26 to August 31, 2021, using a spatiotemporal matching window of 4 hours and 2.5 km. Daily gridded retrieval SSTs from COCTS on both HY-1C and HY-1D were compared with SSTs from the moderate-resolution imaging spectroradiometer (MODIS) on Terra satellite and the visible infrared imaging radiometer (VIIRS) on the Suomi National Polar-orbiting Partnership (S-NPP) satellite. Both daytime and nighttime SSTs from COCTS are consistent with those from MODIS and VIIRS.

description: We prove that if $G$ is a finite simple group which is the unit group of a ring, then $G$ is isomorphic to either (a) a cyclic group of order 2; (b) a cyclic group of prime order $2^k -1$ for some $k$; or (c) a projective special linear group $PSL_n(\mathbb{F}_2)$ for some $n \geq 3$. Moreover, these groups do (trivially) all occur as unit groups. We deduce this classification from a more general result, which holds for groups $G$ with no non-trivial normal 2-subgroup.

description: Recent studies have confirmed the presence of buckminsterfullerene (C$_{60}$) in different interstellar and circumstellar environments. However, several aspects regarding C$_{60}$ in space are not well understood yet, such as the formation and excitation processes, and the connection between C$_{60}$ and other carbonaceous compounds in the interstellar medium, in particular polycyclic aromatic hydrocarbons (PAHs). In this paper we study several photodissociation regions (PDRs) where C$_{60}$ and PAHs are detected and the local physical conditions are reasonably well constrained, to provide observational insights into these questions. C$_{60}$ is found to emit in PDRs where the dust is cool ($T_d = 20-40$ K) and even in PDRs with cool stars. These results exclude the possibility for C$_{60}$ to be locked in grains at thermal equilibrium in these environments. We observe that PAH and C$_{60}$ emission are spatially uncorrelated and that C$_{60}$ is present in PDRs where the physical conditions (in terms of radiation field and hydrogen density) allow for full dehydrogenation of PAHs, with the exception of Ced 201. We also find trends indicative of an increase in C$_{60}$ abundance within individual PDRs, but these trends are not universal. These results support models where the dehydrogenation of carbonaceous species is the first step towards C$_{60}$ formation. However, this is not the only parameter involved and C$_{60}$ formation is likely affected by shocks and PDR age.

description: Polysaccharide has attracted great attentions for its benefits to human health. Polysaccharide from natural sources have diverse anti-inflammatory, anticoagulant and wound healing activities. Polysaccharide is not only valuable in medicine, also widely used in foodstuffs such as gel thickening or emulsifying agents, emulsifiers, fillers. Recently there has been an increase in the demand for polysaccharides, so research into new sources of polysaccharide with plant-based bio-activity is essential. Pseuderanthemum crenulatum (Wall. ex Lindl.) Radlk belong to genus of Pseuderanthemum. Common names (Vietnamese): Xuân hoa răng. This species is native in the forests of Vietnam. The polysaccharide content in P. crenulatum leaves was (7.47 ± 0.6) % in dry weight. The appropriate polysaccharide extraction conditions were determined: material/ water ratio (1g/25ml), extracted temperature of 60°C, extraction time 12 hours. The polysaccharide composition was purified by TCA 10%, with a purity of (55.6 ± 1.19) %. Trong những năm gần đây, polysaccharide là nhóm hợp chất rất được các nhà khoa học trên thế giới quan tâm do các tác dụng quan trọng của chúng về tăng cường miễn dịch, kháng viêm, làm lành vết thương, chống ung thư… Polysaccharide không những có giá trị trong Y học mà còn được sử dụng rộng rãi trong thực phẩm như các chất tạo độ đặc hay tạo gel, chất làm bền nhũ tương, chất độn… Hiện nay, nhu cầu sử dụng polysaccharide từ thực vật ngày càng gia tăng nên việc điều tra, khai thác nguồn polysaccharide mới có hoạt tính sinh học là rất cần thiết. Pseuderanthemum crenulatum (Wall. ex Lindl.) Radlk thuộc chi Pseuderanthemum sp, tên thông thường là cây Xuân hoa răng, là cây mọc tự nhiên trong rừng Việt nam. Trong nghiên cứu này, chúng tôi đã tách chiết, xác định hàm lượng và tinh sạch sơ bộ polysaccharide từ lá cây Pseuderanthemum crenulatum. Hàm lượng polysaccharide trong lá cây Xuân hoa răng đạt (7.47 ± 0.6) % trọng lượng khô. Các điều kiện chiết rút polysaccharide thích hợp đã được xác định: nhiệt độ chiết rút 60°C, tỷ lệ nguyên liệu/nước (1g mẫu khô/25ml nước), thời gian chiết rút 12 giờ. Chế phẩm polysaccharide đã được tinh sạch bằng TCA 10%, có độ sạch đạt (55.6 ± 1.19)%.

description: Vibrio cholerae is the cholera causing agent, divided into two biotypes, including the classical biotype and ElTor biotype. Both of these biotypes caused cholera epidemics in the world. The classical biotype caused 6th cholera pandemic (from 1921 to 1961), and ElTor biotype caused 7th cholera pandemic (from 1961 to the 70s). Haemolysin A, a hemolytic protein of V. cholerae ElT or biotype, is encoded by the hlyA gene. This gene is often used for analyzing genetic relationship between strains in the same species or between species in the same Vibrio genus. Results of analyzing nucleotide and amino acid sequences of hlyA gene of V. cholerae strain causing cholera in Vietnam (named hlyA.VN) showed that: the hlyA.VN gene sequence was similar to the hlyA gene sequences of V. cholerae strains of the 6th and 7th cholera epidemics. The hlyA gene of the 6th cholera epidemic strain was deficient in 11 nuleotides (this deficiency leading to the loss of 4 amino acids in the haemolysin A protein) comparing to hlyA.VN gene and hlyA gene of the 7th cholera epidemic strain. The results of genetic distance analysis as well as phylogenetic tree construction also confirmed V. cholerae causing cholera in Vietnam was closely relationship to the strains causing cholera pandemics in the world. It is great significance for the surveillance of molecular epidemiology to prevent cholera effectively. Vibrio cholerae là tác nhân gây bệnh tả, được chia thành hai typ sinh học, đó là typ sinh học cổ điển và typ sinh học ElTor. Cả hai typ này đã từng gây ra các đại dịch tả trên thế giới. Typ sinh học cổ điển đã từng gây ra đại dịch tả lần thứ 6 (từ năm 1921 đến 1961), còn typ sinh học ElTor đã từng gây ra đại dịch tả lần thứ 7 (từ 1961 đến những năm 70). Haemolysin A, một protein có chức năng làm tan máu của V. cholerae typ sinh học ElTor, được mã hóa bởi gen hlyA. Gene này thường được sử dụng cho các phân tích quan hệ di truyền giữa các chủng trong cùng một loài V. cholerae hay giữa các loài trong cùng một chi Vibrio. Kết quả phân tích trình tự nucleotide và axit amin gen hlyA của chủng V. cholerae gâybệnh ở Việt Nam (hlyA.VN) cho thấy: trình tự gen hlyA.VN có sự tương đồng lớn với trình tự gen hlyA của chủng gây đại dịch tả 6 và 7. Gen hlyA của chủng gây đại dịch tả 6 bị thiếu hụt 11 nuleotide (sự thiếu hụt này dẫn tới sự mất đi 4 axit amin trong phân tử haemolysin A) so với gen hlyA.VN và gene hlyA của chủng gây đại dịch tả 7. Kết quả phân tích khoảng cách di truyền cũng như xây dựng cây phát sinh chủng loại cũng đã khẳng định: chủng gây bệnh ở Việt Nam có quan hệ rất gần với các chủng gây đại dịch tả trên thế giới. Nhận định này có ý nghĩa rất lớn đối với công tác giám sát dịch tễ học phân tử để ngăn chặn bệnh tả hiệu quả.

description: In Vietnam, shrub vegetation accounts for a very high proportion of forest land in the whole country. However, the study of biomass and carbon storage capacity of shrub vegetation type has not been properly considered. In Ha Giang province, there exist many types of shrub vegetation, which originated from slash and burn cultivation. However, these types of shrubs are not only different in terms of fallow periods, but also differ in their distribution over different height. Therefore, the baseline carbon pricing should be calculated for each subregion of the locality. This article presents results of research on carbon storage and carbon baseline building for shrub vegetation in Tung Ba commune, Vi Xuyen district, Ha Giang province (in valley and lowland subregion). This is the scientific data for a rational and sustainable use of shrubs. Việc đưa ra các quyết định đúng đắn về trồng rừng/ tái trồng rừng trên thảm thực vật cây bụi, thì phải căn cứ vào đường cacbon cơ sở của thảm thực vật. Ở Việt Nam, thảm thực vật cây bụi chiếm tỷ lệ rất cao về diện tích đất lâm nghiệp trong toàn quốc. Tuy nhiên, việc nghiên cứu sinh khối và khả năng tích lũy cacbon của kiểu thảm thực vật cây bụi chưa được quan tâm đúng mức. Ở tỉnh Hà Giang, tồn tại nhiều kiểu thảm thực vật cây bụi, có nguồn gốc sau quá trình canh tác nương rẫy. Tuy nhiên, các kiểu thảm cây bụi này không chỉ khác nhau về thời gian bỏ hóa, mà còn có sự khác biệt về sự phân bố trên các độ cao khác nhau. Vì vậy, việc xây dựng đường cacbon cơ sở cần được tính toán cụ thể cho từng tiểu vùng của huyện. Bài báo trình bày kết quả nghiên cứu về khả năng tích lũy cacbon và xây dựng đường cacbon cơ sở cho thảm thực vật cây bụi ở xã Tùng Bá, huyện Vị Xuyên, tỉnh Hà Giang (thuộc tiểu vùng thung lũng và núi thấp). Đây là dẫn liệu khoa học cho việc sử dụng thảm thực vật cây bụi một cách hợp lí và bền vững về mặt môi trường.

description: The theoretical foundations of the phenomenon known as super-radiance still continues to attract considerable attention. Despite many valiant attempts at pedagogically clear presentations, the effect nevertheless still continues to generate some significant confusion. Part of the confusion arises from the fact that super-radiance in a quantum field theory [QFT] context is not the same as super-radiance (super-fluorescence) in some condensed matter contexts; part of the confusion arises from traditional but sometimes awkward normalization conventions, and part is due to sometimes unnecessary confusion between fluxes and probabilities. We shall argue that the key point underlying the effect is flux conservation, (and, in the presence of dissipation, a controlled amount of flux non-conservation), and that attempting to phrase things in terms of reflection and transmission probabilities only works in the absence of super-radiance. To help clarify the situation we present a simple exactly solvable toy model exhibiting both super-radiance and damping.

description: This article is an important content of the research on "Assessment of Forest Tenure Policies and Regulation in Vietnam ". This assessment reviewed 79 legal documents related to forest land tenure that includes: 1 Constitution; 8 Laws; 1 Resolution; 20 Decrees; 30 Circulars, 18 Decisions and 1 Directive. The objective of this paper was to assess some facets of Justice, Dispute Resolution, Gender, Pro-poor and Inclusiveness in the system of Vietnam forest tenure policies. The main research method was based on the assessment framework Voluntary Guidelines on the Responsible Governance of Tenure of Land, Forests and Fisheries. The results of 2 theme groups (a-Access to justice and resolution of tenure rights; and b-Gender equity and pro-poor and inclusiveness), corresponding to the seven sub-themes/criteria showed that its marks were at from 1 to 2 (the system of forest tenure policies in Vietnam has attained “slightly addressed” to “moderately addressed” for the facets of forest tenure rights), has not gained the levels of “mostly addressed” (mark 3) or “fully addressed” (mark 4). Bài báo này là một phần nội dung quan trọng của nghiên cứu “Đánh giá các Chính sách và Quy định hưởng dụng rừng ở Việt Nam”. Công trình nghiên cứu đã rà soát phần lớn các chính sách hiện hành quan trọng của hưởng dụng rừng với tổng số 79 văn bản, gồm: 1 Hiến pháp; 8 Luật; 1 Nghị quyết; 20 Nghị định; 30 Thông tư; 18 Quyết định và 1 Chỉ thị. Mục tiêu của bài viết này là đánh giá các mặt công bằng, giải quyết tranh chấp, giới, vì người nghèo và sự toàn diện trong hệ thống các chính sách hưởng dụng rừng ở Việt Nam. Phương pháp nghiên cứu chính được dựa trên khung đánh giá của Hướng dẫn tự nguyện về Quản trị chịu trách nhiệm của hưởng dụng đất, lâm nghiệp và thủy sản. Kết quả nghiên cứu 2 nhóm chủ đề (a-Tiếp cận đến sự công bằng và giải pháp giải quyết tranh chấp hưởng dụng; b-Giới và công bằng, vì người nghèo và sự toàn diện), tương ứng với 7 chủ đề phụ/tiêu chí đều cho thấy mới đạt mức điểm từ 1 – 2 (tức là hệ thống chính sách hưởng dụng rừng hiện hành ở Việt Nam mới “giải quyết một phần” đến “giải quyết trung bình” các khía cạnh về quyền hưởng dụng rừng), chứ chưa “giải quyết phần lớn” (điểm 3) hoặc “giải quyết đầy đủ” (điểm 4).

description: Ba Vi National Park, one of 28 Vietnamese National Parks, is currently preserved and exploited for a variety of purposes, including the preservation of intact natural forest ecosystems and genetic resources of rare plants and animals. This paper presents the monitoring results of microbial contamination in surface water environment of the Ba Vi National Park (Ha Noi) in the period 2013-2014 and 2018. The results showed that total coliform (TC) density varied from 23 to 11,000 MPN/100ml in bimonthly observation in 2013-2014 which was lower than that one of sampling campaign in 2018, from 900 MPN/100ml to 8,100 MPN/ml. Fecal coliform (FC) densities varied from 0 to 110 MPN/100ml in 2013-2014, lower than in 2018, when it varied from 0 MPN/100ml to 600 MPN/100ml. At several observation times, both TC and FC were higher than the allowable values of the Vietnam national technical regulation QCVN 08-MT: 2015/BTNMT column A1 for surface water quality. The exceeded values of TC and FC than the allowable values and the increase trend from the 2013 to 2018 periods indicated the potential risks to the public health in this region when people use water for domestic and agricultural purposes. Our results provide dataset for environmental management in the Ba Vi National Park in order to protect the eco-environment in parallel with social-economic development. Vườn Quốc gia Ba Vì, một trong 28 vườn quốc gia của Việt Nam hiện đang được bảo tồn và khai thác cho nhiều mục đích, trong đó có bảo tồn nguyên vẹn các hệ sinh thái rừng tự nhiên, các nguồn gen động, thực vật quý hiếm, các đặc sản rừng và các di tích lịch sử, cảnh quan tự nhiên trong vùng. Bài báo trình bày kết quả quan trắc, đánh giá mức độ ô nhiễm vi sinh vật trong môi trường nước mặt tại Vườn Quốc Gia Ba Vì, Hà Nội giai đoạn 2013-2014 và 2018. Kết quả cho thấy mật độ coliform tổng số (TC) biến đổi trong khoảng từ 23 – 11.000 MPN/100ml trong các đợt quan trắc định kỳ 2 tháng/lần trong hai năm 2013 - 2014 và trong khoảng từ 900 – 8.100 MPN/100ml trong một đợt quan trắc năm 2018. Mật độ fecal coliform (FC) biến đổi trong khoảng từ 0 - 110 MPN/100ml năm 2013 -2014 và từ 0 - 600 MPN/100ml vào năm 2018. Vào một số thời điểm quan trắc, mật độ FC và TC vượt giá trị cho phép của quy chuẩn kỹ thuật Quốc Gia QCVN 08-MT:2015/BTNMT cột A1 về chất lượng nước mặt. Các giá trị TC và FC vượt quá giá trị cho phép và xu hướng gia tăng TC và FC từ 2013 -2018 cho thấy nguy cơ tiềm tàng khi người dân sử dụng nguồn nước này cho các mục đích sinh hoạt và nông nghiệp. Như vậy, kết quả của nghiên cứu này nhấn mạnh nhu cầu giám sát thường xuyên chất lượng nước và cần thực hiện các giải pháp hiệu quả để xử lý và quản lý nguồn gây ô nhiễm trong khu vực nhằm bảo vệ môi trường sinh thái song song với phát triển kinh tế - xã hội của khu vực.

(Figs. 30A–D)
Type series. Holotype male, Kibamabangan River at waterfall, Inobong, Crocker Range, Borneo, Malaysia, 5° 51.280 N 116° 0 8.417 E, alt. 433 m asl, 18-ix-2012.
Diagnosis. Genital skeleton very long. In ventral view, gonopore appearing anteriorly and posteriorly truncated, dorsal furrow with two small glandularia platelets.
Description. Male: Colour yellow, in posterior half of dorsum reddish, idiosoma 338 long and 282 wide. Lateral eyes distanced from anterior idiosoma margin. Dorsal shield with five pairs of glandularia, anterior part with three pairs of hyaline, posteriorly directed processes, excretory pore fused with dorsal shield. Dorsal furrow posteriorly with two pairs of small glandularia platelets. Tips of Cx-I extending beyond anterior idiosoma margin, lateral margins with a line of blunt teeth; apodemes of gnathosoma relatively short. Venter anteriorly with a ridge on both sides, which extends posteriorly beyond fourth leg sockets. Genital field with four pairs of acetabula, lateral three pairs in a triangle, medial pair more posteriorly. Gonopore appearing truncated anteriorly and posteriorly in ventral view, but with rounded anterior margin when posterior idiosoma uplifted; lateral to gonopore a row of eight small setae. Genital skeleton (visible in dorsal view in the undissected specimen) very long, length 182. Length/height of P1-P5: 21/10, 44/41, 22/24, 62/26, 33/16; P4 rather stocky. Length of I-leg-4–6: 40, 42, 50. Length of IV-leg-4–6: 62, 70, 60. III-leg-4, IV-leg-4 and -5 each with two, III-leg-5 with three swimming setae.
Female: Unknown.
Etymology. Named for the long genital skeleton.
Remarks. The very long genital skeleton is characteristic for the new species. However, for many Axonopsis species the shape of the genital skeleton is not known. Axonopsis hyporheica Pešić, Smit & Saboori, 2012 from SE Iran has a similarly long genital skeleton, but differs in an elongated idiosoma shape and the presence of three glandularia platelets in the dorsal furrow, the most posterior being longish. Axonopsis gracilipalpis K. Viets, 1935 from Sumatra has a more slender palp, while the four acetabula are lying in an arc.
Distribution. Borneo; known only from the locus typicus.
