Long-term challenge to mangrove in the National park Xuanthuy – data released from shallow subsidence monitoring
Authors: Thuyen Le Xuan 
Published: September 2018

A small mangrove colony growing for several decades on a mud flat on the left side of Balat River mouth has become today a large and healthy forest, containing a high ecosystem service value in the core of the Red River biosphere reserve. As a pioneer ecosystem located at land– water interface in the tropic, there exist always risks to mangroves, especially due to climate change and sea level rise. Sea level rise is a worldwide process, but subsidence is a local problem that can exacerbate these geo-hazards. A monitoring of shallow subsidence has been carried out by using SET-MH technique (developed by the United States Geological Survey) to track the both accretion and land sinking in the core zone of the National Park. The measurement shows the average sedimentation rate of 2.9 cm / yr and the sinking rate of 3.4 cm / yr, since Dec. 30th 2012.
This is the first ground-based observation of shallow subsidence under mangroves in the Tonkin Gulf. As a simple and low cost method, so further expansion of this monitoring could provide more useful information to help identify the generally sinking trend of coastal areas in the Red River Delta and also to protect its own biosphere reserve.

Để đánh giá chất lượng trầm tích và lựa chọn sinh vật chỉ thị giám sát ô nhiễm kim loại nặng trong trầm tích sông, chúng tôi đã đánh giá mức độ ô nhiễm Cu, Pb, Cd trong trầm tích và tích lũy những kim loại nặng này trong 12 mẫu trầm tích và 12 mẫu hến (Corbicula sp.) thu thập tại sông Cầu đoạn chảy qua tỉnh Bắc Giang và Bắc Ninh vào tháng 01 và tháng 4 năm 2018. Kết quả nghiên cứu cho thấy, hàm lượng Pb trong trầm tích lớn nhất (113,20 - 203,91 mg/kg trầm tích khô), tiếp theo là hàm lượng Cu (20,22 - 77,34 mg/kg trầm tích khô), và thấp nhất là hàm lượng Cd (0,22 - 1,28 mg/kg trầm tích khô). Hàm lượng các kim loại này trong mô loài hến (Corbicula sp.) dao động từ 0,04 đến 3,73 mg/kg hến tươi. Kết quả cũng cho thấy hàm lượng Pb trong trầm tích và trong mô loài hến đều vượt quá giới hạn cho phép của QCVN 43:2012/BTNMT và QCVN 08-2:2011/BYT. Phân tích tương quan chỉ ra rằng hàm lượng Cu trong trầm tích có tương quan thuận và chặt chẽ (r = 0,54; p<0,01), hàm lượng Cd không có tương quan (r = 0,27; p>0,05), và của Pb có tương quan thuận và tương đối cao (r = 0,43, p<0,05) với hàm lượng của chính các kim loại nặng đó trong mô hến (Corbicula sp.). Từ kết quả nghiên cứu này cho thấy, có thể sử dụng loài hến (Corbicula sp.) làm sinh vật chỉ thị giám sát ô nhiễm kim loại nặng trong trầm tích tại sông Cầu.
Determination of natural radioactivity in soil samples around gold mining area in Khamkeut district, Bolikhamxay Province, Laos using gamma ray spectrometer with NaI(Tl) detector

Published: September 2018

This paper presented the method of determining the radioactivity of 40K, 226Ra and 232Th in soil samples by gamma-ray spectrometer using NaI (Tl) scintillation detector. The radioactivity of each isotope is calculated based on the net count rate in the energy window characteristic for the 40K, 226Ra and 232Th radioisotopes respectively. We have determined activity concentrations of the natural radionuclides 226Ra,232Th and 40K in 15 soil samples collected around gold mines of Khamkeut district, Bolikhamxay Province, Laos. The average activity concentrations of the natural radionuclides 226Ra, 232Th and 40K are 46.58 ± 7.36 , 71.19 ± 5.42 and 574.62 ± 25.02 Bq.kg-1, respectively. The average activity concentrations of 226Ra and 232Th in this work are higher than those of Bolikhamxay Province, Laos and the world average values. The estimated average outdoor annual effective dose (E) and radium equivalent actitvity (Raeq) are 0.10 ± 0.004 mSv.yr-1 and 192.64 ± 16.12 Bq.kg-1, respectively.
Synthesis and characterization of anatase TiO2:Cu2+ powders prepared via a sol-gel technique
Authors: Loan Trinh Thi 
Published: September 2018

Anatase TiO2 powders doped with different amounts of Cu2+ ions (0, 0.5, 1.0 and 4 mol%) were successfully synthesized by sol-gel method from precursors of TiCl4, (CH3COO)2Cu. Effect of Cu2+ concentrations on the structural and optical properties of TiO2 host was investigated by X-ray diffraction, Raman spectroscopy and diﬀuse reﬂection spectroscopy. The XRD analysis showed that the doped samples exhibit anatase single phase at annealing temperature 600 oC. The Cu2+ contents did not affect on the lattice of TiO2 hot, but affected on positions of these Raman modes. The band gap of the TiO2:Cu2+ was decreased with the increase of doping concentration.

CORRECTIVE FEEDBACK IN ENGLISH CLASS
Authors: Astia Meirina 
Published: September 2018

The design of this study was classroom based observation research. The focus of this study was corrective feedback made by English teachers in the classroom. This study identified occurrences of the correction during the daily conversation course and the way teachers performed the corrective feedback in the classroom. Data were presented under the descriptive way and analyzed inductively in terms of features and facts of teacher’s teaching process (teacher’s corrective feedback). The study revealed that teacher’s corrective feedback is one factor that influences the progress of students in learning English. It did not bother the students in building a communication. The evidence showed that that the teacher applied recasts, explicit correction, and clarification requests. Recasts was dominated the type of corrective feedback used by the teacher because it did not make the students confused. Three criteria of effective corrective feedback occurred in correction given by the teacher. He was consistent in treating the errors, gave correction without breaking the flow of the communication, and did not ridicule the students in giving correction.

Published: September 2018

In connection with a relatively high cost of drill pipes large companies loss caused by rejection achieves tens millions of rubles. And at the same time it is necessary to take into account that the tool-joint thread rejection does not mean at all unworthiness to operation a drill pipe itself as having restored an inter-lock it is possible to continue the operation of a res-tored product. In such a way, one of the priority direc-tions at major repair of drill pipes is a restoration of interlock geometrical joints.
In this paper there is considered a technology for repair of a worn thread in an interlock of drill pipes and its updating at the expense of electric contact weld deposition used into an upset groove. The method of-fered allows keeping a pipe without its shortening at repair at the expense of additional metal application directly upon a thread area and decreasing a thermal impact area and also increasing operation properties of a restored pipe.

Objectif : L’échographie clinique en médecine d’urgence (ECMU) est un outil essentiel de notre pratique. L’objectif principal de notre étude était d’évaluer les caractéristiques des médecins pratiquant l’ECMU au sein de notre territoire. L’objectif secondaire était d’analyser les facteurs influençant une pratique régulière.
Matériel et méthodes : Étude descriptive multicentrique et déclarative, réalisée auprès de médecins urgentistes travaillant au sein d’un réseau territorial de médecine d’urgence à l’aide d’un questionnaire en ligne.
Résultats : Cent onze questionnaires sur 120 envoyés ont été renseignés (92 %). Onze services (92 %) étaient dotés en échographe dont neuf (82 %) en dotation propre. Soixantesix médecins (59 %) déclaraient pratiquer l’échographie régulièrement. La FAST (focused assessment with sonography for traumas) était la plus pratiquée (80 médecins, 72 %), suivie de l’exploration hémodynamique (50 médecins, 45 %) et pleurale (44 médecins, 40 %). Dans le groupe des médecins ne pratiquant pas l’ECMU, 17 médecins sur 22 (77 %) l’expliquaient par un manque de formation. Dans le même temps, l’intérêt porté à l’ECMU par les urgentistes était coté à 7 ± 2 sur une échelle de 0 à 9. Les facteurs associés à la fréquence de la pratique de l’ECMU étaient le sexe (p < 0,001), le type d’activité (p = 0,005), le type de formation à l’échographie (p < 0,001) et l’ancienneté d’équipement de son service en échographe (p < 0,001).
Conclusion : Cette enquête a montré que la pratique régulière était majoritaire avec un intérêt porté par les praticiens à l’ECMU élevé. Cependant, le frein principal à son développement était un niveau de formation jugé insuffisant par certains praticiens.
Effects of discontinuation of chronic medication in primary care: a systematic review of deprescribing trials

Published: September 2018

BackgroundPolypharmacy is becoming more prevalent and evaluation of appropriateness of medication use is increasingly important. The primary care physician often conducts the deprescribing process; however, there are several barriers to implementing this.AimTo examine the feasibility and safety of discontinuation of medication, with a focus on studies that have been conducted in the community, that is, primary care (or general practice) and nursing homes.Design and settingThis systematic review included randomised controlled trials published in 2005–2017, which studied withdrawal of long-term drugs prescribed in primary care settings and compared continuing medication with discontinuing.MethodPubMed and EMBASE searches were conducted and the extracted data included the number of patients who successfully stopped medication and the number of patients who experienced relapse of symptoms or restarted medication.ResultsA total of 27 studies reported in 26 papers were included in this review. The number of participants in the studies varied from 20 to 2471 and the mean age of participants ranged from 50.3 years to 89.2 years. The proportion of patients who successfully stopped their medication varied from 20% to 100%, and the range of reported relapse varied from 1.9% to 80%.ConclusionOnly a few studies have examined the success rate and safety of discontinuing medication in primary care, and these studies are very heterogeneous. Most studies show that deprescribing and cessation of long-term use seem safe; however, there is a risk of relapse of symptoms. More research is needed to advise physicians in making evidence-based decisions about deprescribing in primary care settings.

Published: September 2018

BackgroundThe incidence of liver disease is increasing in the UK and primary care is a key setting where improvement in the detection and management of liver disease is required. Little is known about GPs’ understanding and confidence in detecting liver disease.AimTo explore GPs’ experiences of liver disease with a focus on early detection and interpretation of liver function tests (LFTs).Design and settingA qualitative study employing semi-structured interviews of a purposive sample of GPs from five UK primary care study sites.MethodTelephone and face-to-face interviews of GPs were undertaken. Data were analysed thematically, using a constant comparative approach.ResultsFrom a total of 25 GP interviews (N= 25), four themes were identified from the data: test-requesting behaviour, confidence and challenges in diagnosing disease, access to specialist tests, and guidance and education. Participants’ descriptions of how they request and interpret LFTs varied widely. Concern over missing diagnoses was a common reason for requesting blood tests; patients with mildly abnormal LFTs and those at risk of non-alcoholic fatty liver disease (NAFLD) were a particular cause of concern. GPs saw themselves as generalists, with a reluctance to take on specialist investigations. Guidelines promoted confidence for some clinicians, but others felt that liver disease was too complex to be amenable to simple instructions. Most felt that they did not have access to relevant, focused education on liver disease.ConclusionLiver disease is not perceived as a priority in primary care. If GPs are to take on a greater role in identification and management of liver disease, support is needed to promote awareness, knowledge, and confidence.

Published: September 2018

BackgroundAsthma and chronic obstructive pulmonary disease (COPD) share many characteristics and symptoms, and the differential diagnosis between the two diseases can be difficult in primary care. This study explored potential overlap between both diseases in a primary care environment.AimTo quantify how commonly patients with COPD have a concomitant diagnosis of asthma, and how commonly patients with asthma have a concomitant diagnosis of COPD in UK primary care. Additionally, the study aimed to determine the extent of possible misdiagnosis and missed opportunities for diagnosis.Design and settingPatients with validated asthma and patients with validated COPD in primary care were identified from the UK Clinical Practice Research Datalink (CPRD) in separate validation studies, and the diseases were confirmed by review of GP questionnaires.MethodThe prevalence of concurrent asthma and COPD in validated cases of either disease was examined based on CPRD coding, GP questionnaires, and requested additional information.ResultsIn total, 400 patients with COPD and 351 patients with asthma in primary care were identified. Of the patients with validated asthma, 15% (n = 52) had previously received a diagnostic COPD Read code, although COPD was only likely in 14.8% (95% confidence interval [CI] = 11.3 to 19.0) of patients with validated asthma. More than half (52.5%, n = 210) of patients with validated COPD had previously received a diagnostic asthma Read code. However, when considering additional evidence to support a diagnosis of asthma, concurrent asthma was only likely in 14.5% (95% CI = 11.2 to 18.3) of patients with validated COPD.ConclusionA concurrent asthma and COPD diagnosis appears to affect a relative minority of patients with COPD (14.5%) or asthma (14.8%). Asthma diagnosis may be over-recorded in people with COPD.
