description: Despite a positive contribution to economic – social development, the growth of piggeries has caused heavily environmental pollution. Currently, treated wastewater of pig farms unfortunately does not meet the national discharge standards yet. This paper presents some research results on the removing COD, nitrogen and phosphorus in piggery wastewater after anaerobic (biogas) process at pilot scale by the combined system using Phragmites australis, Cyperus alternifolius, Vetiveria zizanioides and Eichhornia crassipes. The experimental results showed that the wastewater loading rate of 47.35 l/m2.day with initial concentrations of 203.24 mg COD/l, 111.94 mgTN/l and 13.61 mgTP/l gave removal efficiency of 71.66 %, 79.26 % and 69.65 %, respectively. Thus, the removed quantity of total nitrogen (TN) and total phosphorus (TP) was of 4201.35 mg TN/m2.day và 448.76mg TP/m2.day. The obtained results indicated that the flow wetland system, using Phragmites australis, Cyperus alternifolius, Vetiveria zizanioides and Eichhornia crassipes has a rather high COD, TN and TP removal efficiency with simple operation so that it could be feasible if applied for treating pig wastewater. However, the system should be functioned longer for taking data and for evaluating its stability. Mặc dù có những đóng góp tích cực cho sự phát triển kinh tế - xã hội, việc phát triển chăn nuôi lợn đã gây ô nhiễm môi trường nghiêm trọng. Hiện nay, nước thải chăn nuôi lợn từ các cơ sở chăn nuôi sau xử lý vẫn chưa đáp ứng được các tiêu chuẩn thải của quốc gia và tiêu chuẩn ngành. Bài báo này trình bày kết quả nghiên cứu về khả năng loại bỏ COD, nitơ (N) và phôtpho (P) trong nước thải chăn nuôi lợn đã qua xử lý bằng hầm biogas của hệ thống phối hợp cây Sậy, Thủy Trúc, cỏ Vetiver và Bèo Tây ở qui mô pilot. Kết quả thực nghiệm ở tải lượng 47,35 l/m2.ngày, với COD, tổng nitơ (TN) và tổng phôtpho (TP) đầu vào trung bình là 203,24 mg/l, 111,94 mg/l và 13,61 mg/l, tương ứng, thì hiệu suất xử lý lần lượt là 71,66 %; 79,26 % và 69,65 %. Như vậy lượng TN và TP loại bỏ là 4201,35 mgN/m2.ngày và 448,76 mgP/m2.ngày. Kết quả nhận được cho thấy hệ thống sử dụng cây Sậy, Thủy Trúc, cỏ Vetiver và Bèo Tây có hiệu quả loại bỏ COD, TN và TP khá cao trong khi vận hành đơn giản nên có triển vọng áp dụng trong điều kiện thực tế để xử lý nước thải chăn nuôi lợn. Tuy nhiên để đánh giá tính ổn định, hệ thống cần được hoạt động với thời gian lâu dài hơn.

description: The unconditionally squeezing of the collective spin of an atomic ensemble in a laser driven optical cavity (I. D. Leroux, M. H. Schleier-Smith, and V. Vuletic, Phys. Rev. Lett 104, 073602 (2010)) is studied and analyzed theoretically. Surprisingly, we find that the largely detuned driving laser can improve the scaling of cavity squeezing from $S^{-2/5}$ to $S^{-2/3}$, where S is the total atomic spin. Moreover, we also demonstrate that the experimental imperfection of photon scattering into free space can be efficiently suppressed by detuning.

description: Consider an exact couple in a semiabelian category in the sense of Palamodov, i.e., in an additive category in which every morphism has a kernel as well as a cokernel and the induced morphism between coimage and image is always monic and epic. Assume that the morphisms in the couple are strict, i.e., they induce even isomorphisms between their corresponding coimages and images. We show that the classical construction of Eckmann and Hilton in this case produces two derived couples which are connected by a natural bimorphism. The two couples correspond to the a priori distinct cohomology objects, the left resp. right cohomology, associated with the initial exact couple. The derivation process can be iterated under additional assumptions.

description: The research aims to assess the current groundwater resources management in Bac Lieu province. The combination of descriptive statistic and interview approach (including individual interview and key informant panel) were applied based on the principles of water governance framework developed by the Organization of Economic Co-operation and Development (OECD) to assess the policy coherence and the transparency and stakeholder engagement of the groundwater management. The study showed that the current groundwater resources management improved overtime; however, the policies were not completely sufficient and the responsibility of the units related to the groundwater resources management was not indicated clearly yet. Thus, overlaps in function of different management units are found and the access of the local people to the groundwater management was limited. In addition, the stakeholder involvement in managing the groundwater resources was in short of both amount and qualification. The separation of powers seems to be higher and higher, the local government has the main responsibility to manage the groundwater and the communities, especially the local people still have low rate of participation in the groundwater resources management process. Nghiên cứu được thực hiện nhằm đánh giá hiện trạng quản lý nguồn tài nguyên nước dưới đất (NDĐ) tại tỉnh Bạc Liêu. Sự kết hợp giữa phương pháp thống kê mo tả va phương pháp phỏng vấn (bao gồm phỏng vấn cá nhân và phỏng vấn chuyên gia)dựa trên những quy định về quản trị tài nguyên nước của Tổ chức Hợp tác và Phát triển Kinh tế (OECD – Organization for Economic Co-operation and Development) được áp dụng để đánh sự chặt chẽ của các chính sách quản lý, sự minh bạch của công tác quản lý và sự tham gia của các bên có liên quan. Kết quả cho thấy, cơ chế quản lý nguồn tài nguyên NDĐ đã và đang dần hoàn thiện, song các chính sách quản lý vẫn còn chưa đầy đủ và trách nhiệm của các đơn vị quản lý vẫn chưa được quy định rõ ràng. Vì vậy, đến nay công tác quản lý còn phát sinh sự chồng chéo và thiếu sự phối hợp giữa các cơ quan chức năng có liên quan cũng như sự liên kết giữa cơ quan quản lý địa phương và người sử dụng tài nguyên NDĐ. Thêm vào đó, các bên có liên quan tham gia vào quản lý nguồn tài nguyên NDĐ còn hạn chế về cả số lượng và năng lực, trong đó chính quyền địa phương là đơn vị quản lý chính; do vậy, sự tập trung quyền hạn vào một chủ thể (chính quyền địa phương) là rất cao và sự tham gia của cộng đồng, đặc biệt là người sử dụng NDĐ, còn hạn chế.

description: The 2023 state elections in Karnataka, one of the richest states in India, with the IT hub Bengaluru as its capital, threw up an issue of state sovereignty in the campaign crossfire between the country’s two leading political parties - the right wing Bharatiya Janata Party and centre-left Indian National Congress. The incident brought back memories of the Kannada sub-nationalism project in the 1980s which came to be known as the Gokak movement. That crusade for Kannada primacy may have been the best opportunity for language activists to replicate, in Karnataka, the electoral success of the Dravida Munnetra Kazhagam’s1 sub-nationalism political project on Tamil exceptionalism in the neighbouring state, Tamilnadu. The diverse linguistic space of the region, the legacy of the Mysore princely state and the persona of Kannada cinema superstar Dr Rajkumar (who supported the movement at first and did not follow through with a political role), may all have played an important part in the fate of the Kannada language movement. The INC won the electoral contest but we may see the re-emergence of old faultlines and in the atmosphere of majoritarian nationalism of centralisation in a federal set-up and the beginnings of a new frontline of cultural wars in India.

description: Industry decarbonization is a key a challenge towards the transition to climate neutrality. Indeed, there is a need to satisfy heat at temperatures higher than 150 ◦C in relevant industrial sectors by upgrading lower temperature heat flows, such as heat from renewable heat sources, ambient heat or industrial waste heat. High temperature heat pumps (HTHP) can upgrade such heat flows enabling great savings in carbon emissions. New refrigerants are needed to develop HTHPs achieving high performances at high temperatures. This paper proposes the use of a new zeotropic mixture composed of carbon dioxide and acetone as the refrigerant of HTHPs working in the temperature range of 150–220 ◦C. The new fluid is compared with existing pure refrigerants currently used. The thermodynamic characterization of the CO2/acetone mixtures shows temperature glides below 50 K for CO2 mass fractions up to 10%. The best HTHP performance is shown for the mixture 5% CO2/95% acetone in mass fraction. For instance, such a mixture obtains a COP of 5.63 when the target outlet sink temperature is 200 ◦C and the temperature difference between the outlet heat sink and the inlet heat source is 70 K, showing an improvement of 46% compared to pure acetone.

description: This pilot aims at assessing the flood risk in selected areas, its impact on urban areas and the associated risk for population. It will use Sentinel-1 and Sentinel-2 data and relevant processing chains to generate time-series of imagery and automatically detect changes within a given period. The output will be exposed through the MEEO (pilot coordinator) platform whose data cube technology will be enriched with additional relevant datasets to provide both citizens and experts with a Flood Risk & Impact Assessment dashboard based on indicators, time-series charts or forecasting maps. The objective is to have a smart organization of the heterogeneous relevant datasets that facilitates the analysis of the data available and, therefore, the monitoring activities over an AoI.The current application (running in the SatCen GEO-DAMP platform) will be extended by incorporating Sentinel-2 change detection, enhancing its interoperability, expanding its functionality to cover other areas and periods.The Char-Piya region (Bangladesh), which was used to validate current results, will also serve for validating the enhanced service that will allow the monitoring of the construction of settlements (i.e. Rohingya refugee camps) and the impact of floods during the Monsoon period.AcknowledgmentThe e-shape project has received funding from the European Union's Horizon 2020 research and innovation programme under grant agreement 820852.

description: Solar coronal mass ejections (CMEs) are main drivers of the most powerful non-recurrent geomagnetic storms. In the extreme-ultraviolet range, CMEs are accompanied by bright post-eruption arcades and dark dimmings. The analysis of events of the Solar Cycle 23 (Chertok et al., 2013, Solar Phys. 282, 175) revealed that the summarized unsigned magnetic flux in the arcades and dimming regions at the photospheric level, $Φ$, is significantly related to the intensity (Dst index) of geomagnetic storms. This provides the basis for the earliest diagnosis of geoefficiency of solar eruptions. In the present article, using the same data set, we find that a noticeable correlation exists also between the eruptive magnetic flux, $Φ$, and another geomagnetic index, Ap. As the magnetic flux increases from tens to $\approx 500$ (in units of $10^{20}$ Mx), the geomagnetic storm intensity measured by the 3-hour Ap index, enhances in average from Ap $\approx 50$ to a formally maximum value of 400 (in units of 2 nT). The established relationship shows that in fact the real value of the Ap index is not limited and during the most severe magnetic storms may significantly exceed 400.

description: The unique body plan of frogs (Lissamphibia: Anura) has been largely conserved from at least 200 Myr and its evolution from a more generalized tetrapod condition is still poorly understood, in part due to the scarce early fossil record of Salientia, the anuran total-group. The origin of the anuran Bauplan has been classically explained as an adaptation to jumping, but recent studies incorporating new data in a phylogenetic context have challenged the popular jumping hypothesis. Here we revisit and test this hypothesis from a palaeobiological perspective by integrating limb data from a wide range of extant and fossil frogs. We first explored the evolution of limb proportions from the Jurassic to the Paleogene to understand when the present limb diversity originated and whether, and to what extent, limb proportions have been conserved over the last 200 Myr. We then inferred the locomotor capabilities of extinct species by phylogenetic flexible discriminant analysis and, from these inferences, we studied the locomotor diversity of frogs over geological time and reconstructed the ancestral state for frog-like salientians. The evolution of limb proportions is characterized by an early diversification that was underway in the Jurassic, followed by a repeated convergence over a limited area of the morphospace that was already explored by the Early Cretaceous. In agreement with this early limb diversity, the Jurassic stem species were also locomotory diverse and their inferred locomotor modes do not support the jumping hypothesis. We propose that the patterns found herein of repeated convergent evolution of both limb proportions and locomotor capabilities over geological time hamper any attempt to confidently infer the ancestral locomotion mode and, therefore, it might be time to start focusing on other hypotheses on the origin of the anuran Bauplan that are not related to locomotion.

description: Lead (Pb) recycling activities in Dong Mai village, Chi Dao commune, Van Lam district, Hung Yen province have been taking place for more than 30 years. The development of recycling activities contributed to the improvement of the local economics. However, along with economic development, Dong Mai craft village is facing to serious pollution. Soil, air and water polluted by lead (Pb) caused food containing Pb at higher levels than allowed limit from 20 to 40 times. The pollution had the bad effect on human health in this village. The investigation results showed that 100 % of employee who participated on melting lead and 63.5 % of local children were poisoned by Pb. Besides, the local people got diseases relating to skin, eyes, etc. This situation requires the provincial authorities to find immediate solutions to reduce the impacts of Pb recycling activities to environment and human.

description: A test rig has been produced to investigate the transient and steady state behaviour of a domestic gas fired boiler of the high thermal capacity type. The boiler and its test rig have been modelled and the developed model has given responses that show good agreement with those obtained by experimentation. The boiler model has also been used satisfactorily to simulate other tests for which experimental data is available. Additional mathematical models have been derived to give realistic simulated part loads for the boiler model, these represent a lounge and its skirting heating system and a domestic hot water storage system. Combinations of these models have been used to investi gate the influence of various control systems on boiler and system efficiencies and energy consumption.

description: Excerpts from the report: The Elkhart River Basin is located in northeastern Indiana, 130 miles north of Indianapolis, and encompasses about 447,360 acres (about 700 square miles) in parts of four counties (Elkhart, Kosciusko, LaGrange, and Noble). Drainage flows are predominately westward and north-westward. There are numerous natural lakes in the Basin, many of which are in series along the major tributaries. The purpose of the study is to evaluate the water and related land resources, identify problems associated with their use and development, determine present and future needs for resource development, and propose alternative plans for the orderly development of these resources. The study included an evaluation of the importance of agriculture and related economic activities in the Basin, the State of Indiana and the nation. Aspects analyzed and projected include land use, output of agricultural products, agricultural employment, and expected shifts of agricultural land to other uses. Projections were made of the need for developing water and related land resources for food production, rural and municipal water supply, and outdoor recreation. Resource developments required to meet short and long range needs were identified. An early action plan was developed to meet projected needs for the year 1990. Opportunities for meeting long range projected needs for 2020 were considered in lesser detail.

description: The newly planned lead recycling zone in Dong Mai village has been operating with primary treatment systems using lime to neutralize acid in wastewater is a good sign for the local environment, yet the real problem that needs further attention and proper solutions is the accumulation of heavy metals typically lead (Pb) and cadmium (Cd) in agricultural land near the old Pb recycling area. In this context, 27 soil samples were collected and analyzed by AAS method to assess the situation and the quality of the agricultural soil. The results showed that the levels of Cd in the soil were still in acceptable level according to National Regulation. However, the lead contents in all of the soil samples exceeded National Regulation. The level of Pb pollution in soil was inversely proportional to the distance with old lead melting zone. The lead content in the soil sample collected at the distance of 50 m radius to the old melting zone reached 7070 ppm, which was 100 times higher than the allowable value of National Regulation. Khu tái chế chì mới tại thôn Đông Mai đã được quy hoạch và đi vào hoạt động cùng hệ thống xử lý sơ bộ với vôi bột là một tín hiệu đáng mừng cho môi trường nơi đây, nhưng vấn đề cần quan tâm và giải quyết triệt để là sự tích lũy một lượng lớn kim loại nặng điển hình là chì (Pb) và cađimi (Cd) trong đất nông nghiệp gần những khu tái chế chì cũ. 27 mẫu đất đã được thu thập và phân tích bằng phương pháp AAS để đánh giá tình trạng, chất lượng đất nông nghiệp tại đây. Kết quả cho thấy hàm lượng Cd trong đất vẫn trong mức độ cho phép theo Quy chuẩn quốc gia. Tuy nhiên, 100% các mẫu đất đều có hàm lượng chì vượt quá mức cho phép theo Quy chuẩn quốc gia. Mức độ ô nhiễm Pb trong đất tỷ lệ nghịch với khoảng cách tới khu lò nấu chì cũ. Mẫu đất cách 50 m so với khu vực lò cũ có hàm lượng chì lên tới 7070 ppm, gấp hơn 100 lần so với Quy chuẩn quốc gia.

description: We note the possibility to perform a parametrically improved search for gauged baryon ($B$) and baryon minus lepton ($B-L$) Dark Photon Dark Matter (DPDM) using auxiliary channel data from LISA Pathfinder. In particular we use the measurement of the differential movement between the test masses (TMs) and the space craft (SC) which is nearly as sensitive as the tracking between the two TMs. TMs and SC are made from different materials and therefore have different charge-to-mass ratios for both $B-L$ and $B$. Thus, the surrounding DPDM field induces a relative acceleration of nearly constant frequency. For the case of $B-L$, we find that LISA Pathfinder can constrain previously unexplored parameter space, providing the world leading limits in the mass range $4\cdot 10^{-19}\,\text{eV}

description: We measure the magnetic penetration depth $Δλ(T)$ for NdO$_{1-x}$F$_{x}$BiS$_{2}$ ($x$ = 0.3 and 0.5) using the tunnel diode oscillator technique. The $Δλ(T)$ shows an upturn in the low-temperature limit which is attributed to the paramagnetism of Nd ions. After subtracting the paramagnetic contributions, the penetration depth $Δλ(T)$ follows exponential-type temperature dependence at $T\ll T_c$. Both $Δλ(T)$ and the corresponding superfluid density $ρ_s(T)$ can be described by the BCS model with an energy gap of $Δ(0)$ $\approx$ 2.0 $k_BT_c$ for both $x$ = 0.3 and 0.5, suggesting strong-coupling BCS superconductivity in the presence of localized moments for NdO$_{1-x}$F$_{x}$BiS$_{2}$.

description: Vietnam is facing big challenges in terms of environmental pollution caused by natural agents and anthropogenic activities. Environmental pollution in Vietnam is present in air, water and soil environments in many areas with contaminants including total suspended particles (TSP), organic substances, heavy metals, nutrients including ammonium, phosphate exceeding the allowable values of national standard. One of the most important causes of environmental pollution is the legal powers of environmental protection organizations, especially the environmental police force, not strong enough. In addition, the awareness of the people about environmental protection is very weak. Improving the system of laws on environmental protection, including sanctions that are strong enough to prevent violations, is of the most importance to enhance the effectiveness of environmental management and protection in Vietnam. On the other hand, educating people and even school children about environmental protection is a very meaningful activity to reduce the pressures and challenges of environmental management and protection in Vietnam. Việt Nam đang phải đối mặt với những thách lớn về ô nhiễm môi trường gây ra bởi các tác nhân tự nhiên và các hoạt động của con người. Ô nhiễm môi trường ở Việt Nam biểu hiện ở cả môi trường không khí, nước và đất tại nhiều khu vực với hàm lượng các chất ô nhiễm gồm bui thô TSP. các chất hữu cơ, kim loại nặng, các chất dinh dưỡng gồm amoni, phosphat vượt quá tiêu chuẩn cho phép. Một trong những nguyên nhân quan trọng gây ô nhiễm môi trường là sức mạnh pháp lý của các cơ quan tổ chức hoạt động trong lĩnh vực môi trường, đặc biệt là lực lượng cảnh sát môi trường, chưa đủ mạnh. Bên cạnh đó, ý thức của người dân về giữ gìn bảo vệ môi trường còn rất yếu. Việc hoàn thiện hệ thống luật pháp về bảo vệ môi trường bao gồm các chế tài đủ mạnh để ngăn chặn các vi phạm là quan trọng hàng đầu nhằm tăng cường hiệu quả quản lý và bảo vệ môi trường ở Việt Nam. Mặt khác, giáo dục tuyên truyền ý thức cho người dân và thậm chí các học sinh trong trường học về giữ gìn bảo vệ môi trường là hoạt động rất ý nghĩa nhằm giảm bớt các áp lực và thách thức trong quản lý và bảo vệ môi trường ở Việt Nam.

description: We propose a novel definition of a holographic light hadron jet and consider the phenomenological consequences, including the very first fully self-consistent, completely strong-coupling calculation of the jet nuclear modification factor $R_{AA}$, which we find compares surprisingly well with recent preliminary data from LHC. We show that the thermalization distance for light parton jets is an extremely sensitive function of the \emph{a priori} unspecified string initial conditions and that worldsheets corresponding to non-asymptotic energy jets are not well approximated by a collection of null geodesics. Our new string jet prescription, which is defined by a separation of scales from plasma to jet, leads to the re-emergence of the late-time Bragg peak in the instantaneous jet energy loss rate; unlike heavy quarks, the energy loss rate is unusually sensitive to the very definition of the string theory object itself. A straightforward application of the new jet definition leads to significant jet quenching, even in the absence of plasma. By renormalizing the in-medium suppression by that in the vacuum we find qualitative agreement with preliminary CMS $R_{AA}^{jet}(p_T)$ data in our simple plasma brick model. We close with comments on our results and an outlook on future work.

description: This paper aims to assess the current status and effectiveness of coastal wetland utilization in Duy Xuyen district, Quang Nam province, and to propose solutions to improve land use and conserve the existing wetlands of the locality. Research results show that there are five types of wetlands in Duy Xuyen district: wetlands with tidal forests, streams, freshwater ponds, aquaculture ponds, and irrigated land. The wetland areas in Duy Xuyen district are mainly distributed in 3 communes: Duy Thanh, Duy Nghia and Duy Vinh and there is a noticeable decrease in the period from 2010 to 2016. The calculated results show that the total economic value of wetlands in the study area includes: direct use value is 41,276,949,000 VND/year (accounting for 99.61%), non-use value is 162,855,000 VND/year (accounting for 0.39 %). In which, the social and environmental economic values of wetland use types are totally different. Bài báo này nhằm mục đích đánh giá thực trạng và hiệu quả sử dụng đất ngập nước ven biển trên địa bàn huyện Duy Xuyên, tỉnh Quảng Nam, trên cơ sở đó đề xuất những giải pháp nhằm nâng cao hiệu quả sử dụng và bảo tồn diện tích đất ngập nước hiện có của địa phương. Kết quả nghiên cứu cho thấy, trên địa bàn huyện Duy Xuyên có 5 kiểu đất ngập nước: vùng đất ngập nước có rừng gian triều, sông suối, vùng nước ngọt, ao nuôi trồng thủy sản, đất được tưới tiêu. Diện tích đất ngập nước trên địa bàn huyện Duy Xuyên chủ yếu phân bố ở 3 xã: Duy Thành, Duy Nghĩa và Duy Vinh và có sự biến động giảm rõ rệt từ năm 2010 đến năm 2016. Kết quả điều tra cho thấy tổng giá trị kinh tế của đất ngập nước trên địa bàn nghiên cứu bao gồm: giá trị sử dụng trực tiếp (41,276,949,000 đồng/năm, chiếm 99.61%), giá trị phi sử dụng (chiếm 0.39% đạt 162,855,000 đồng/năm). Trong đó, hiệu quả xã hội và môi trường giữa các kiểu sử dụng đất ngập nước không đồng đều.

description: 1. Myrmica molesta, Say, Bost. Journ. Nat. Hist. i. 293. 6. I have carefully examined several individuals of the worker of this species from Makassar, and compared them with specimens obtained from North America, Brazil, and from houses in London, and can detect no specific difference; the examples from Celebes are paler at the apex of the abdomen; beyond this, I see no difference. I consider M. molesta a cosmopolitan species, which has been carried in merchandize to all parts of the world.

description: Biochar is defined as a carbon-rich, fine-grained, porous substance, which is produced by pyrolysis biomass with little or no oxygen. Biochar is usually produced from crop residues, wood biomass, animal litters, and solid wastes. Recently, biochar is increasingly receiving attention as an environmental-friendly approach, especially as a climate change mitigation strategy. Biochar is especilly demonstrated to remove diesel oil (DO) from soil and water. In this report, 4 biofilm forming bacteria including Klepsiellasp. VTD8, Pseudomonas sp. BQN21, Rhodococcussp. BN5 and Stenotropomonassp. QND8 were used to attach to biochar produced from husk to estimate the capacity of their DO removal. As the results, removal efficiency of biofilm formed by each strain VTD8, BQN21, BN5 and QND8 were 67, 73, 75 and 68 % with initial concentration of 39 g/l, respectively. On the other hand, mix species biofilm attached to husk carrier and without carrier degraded 98 and 78 %. Using husk without bacteria as absortion control, the amount of DO removal was 23 %. These results gave hint that using biochar produced from husk as carrier for biofilm forming bacteria to attach may increase efficiency of DO pollution treatment. Than sinh học (biochar) là một chất xốp có các gốc carbon và có nguồn gốc từ quá trình nhiệt phân sinh khối các loại chất thải, động, thực vật,… dưới điều kiện hạn chế oxy hoặc không có oxy.Hiện nay biochar đã được ứng dụng rộng rãi trong xử lý môi trường. Đặc biệt các biochar còn được chứng minh là có thể xử lý dầu diesel (diesel oil - DO) có trong đất và nước. Trong nghiên cứu này, chúng tôi sử dụng 4 chủng vi khuẩn tạo màng sinh học tốt là Klepsiella sp. VTD8, Pseudomonas sp. BQN21, Rhodococcus sp. BN5 và Stenotropomonas sp. QND8 để gắn lên chất mang là biochar làm từ trấu nhằm đánh giá hiệu quả xử lý DO của chúng. Kết quả cho thấy, sau 7 ngày, các chủng VTD8, BQN21, BN5 và QND8 có khả năng phân hủy 67, 73, 75 và 68 % DO với hàm lượng ban đầu là 39 g/l. Trong khi đó, hiệu suất của màng sinh học tạo thành bởi hỗn hợp các chủng này khi không có chất mang biochar trấu và khi có chất mang biochar trấu lần lượt là 78 và 98 %. Còn sử dụng chất mang biochar trấu không có vi sinh vật làm đối chứng thì thu được hiệu suất hấp phụ DO là 23 %. Như vậy, kết quả này mở ra tiềm năng ứng dụng biochar trấu làm chất mang cho các chủng vi khuẩn tạo màng sinh học để nâng cao hiệu quả xử lý ô nhiễm dầu.

description: Within the two-center shell model parameterization we have defined the optimal shape which fissioning nuclei attain just before the scission and calculated the total deformation energy (liquid drop part plus the shell correction) as function of the mass asymmetry and elongation at the scission point. The three minima corresponding to mass symmetric and two mass asymmetric peaks in the mass distribution of fission fragments are found in the deformation energy at the scission point. The calculated deformation energy is used in quasi-static approximation for the estimation of the total kinetic and excitation energy of fission fragments and the total number of emitted prompt neutrons. The calculated results reproduce rather well the experimental data on the position of the peaks in the mass distribution of fission fragments, the total kinetic and excitation energy of fission fragments. The calculated value of neutron multiplicity is somewhat larger than experimental results.
