The Role of Hydrological Signatures in Calibration of Conceptual Hydrological Model
Authors: Melišová Eva , Vizina Adam , Staponites Linda R. , Hanel Martin
Published: December 2020

Determining an optimal calibration strategy for hydrological models is essential for a robust and accurate water balance assessment, in particular, for catchments with limited observed data. In the present study, the hydrological model Bilan was used to simulate hydrological balance for 20 catchments throughout the Czech Republic during the period 1981–2016. Calibration strategies utilizing observed runoff and estimated soil moisture time series were compared with those using only long-term statistics (signatures) of runoff and soil moisture as well as a combination of signatures and time series. Calibration strategies were evaluated considering the goodness-of-fit, the bias in flow duration curve and runoff signatures and uncertainty of the Bilan model. Results indicate that the expert calibration and calibration with observed runoff time series are, in general, preferred. On the other hand, we show that, in many cases, the extension of the calibration criteria to also include runoff or soil moisture signatures is beneficial, particularly for decreasing the uncertainty in parameters of the hydrological model. Moreover, in many cases, fitting the model with hydrological signatures only provides a comparable fit to that of the calibration strategies employing runoff time series.
Isotopic Evolution in Snowpacks from a Typical Temperate Glacier in the South-Asia Monsoon Region

Published: December 2020

In this study, snow samples collected from nine snowpacks from Mt. Yulong are measured to examine the monthly and annual isotopic variation. The results indicate that the late autumn and winter snow sampled in 2008/2009 show a similar high–low–high δ18O variation. In spring, the high–low–high curve still exists in the lower layers (<1.5 m), while relatively high values are witnessed in the upper layers (>1.5 m). Isotopic homogenization, smoothing the vertical variation of δ18O in snow, is observed in June and July when snow melting occurs. Samples collected in April of 2009, 2012 and 2017 show significant differences, suggesting annual changes of isotope contents in snow. This study suggests that the isotope contents in the snow profile can reflect meteorological information. At the monthly scale, we can distinguish the information on snow accumulation and melting by determining the monthly variation of vertical isotope contents in snow. At the annual scale, we can analyze the annual difference of corresponding meteorological factors. Collectively, observing the stable isotopes in snow could provide evidence for climate change, particularly when climatic data are lacking or are challenging to obtain in cold glacierized regions.

Published: December 2020

Effective evaluations of the future urban expansion impacts (UEI) on surface runoff in alpine basins are full of challenges due to the lack of reliable methods. Our objective was to provide a new approach by coupling the Land Use Scenario Dynamics-urban (LUSD-urban) and Soil Conservation Service-Curve Number (SCS-CN) models to estimate the future UEI on surface runoff. Taking the Qinghaihu-Huangshui basin (QHB) in the Tibetan Plateau, China, as an example, we first applied the SCS-CN model to quantify the surface runoff in 2000 and 2018 and analyzed the changes in surface runoff. Next, we applied the LUSD-urban model to simulate urban expansion under five localized shared socioeconomic pathways (SSPs) from 2018 to 2050. Finally, we assessed the UEI on surface runoff in the QHB from 2018 to 2050. We found that coupling the LUSD-urban and SCS-CN models could effectually evaluate the future UEI on surface runoff. Compared with the combination of the Future Land Use Simulation (FLUS) and SCS-CN models, our method reduced the absolute evaluation errors from 3.40% and 11.78% to 0.18% and 4.23%, respectively. In addition, the results showed that future urban expansion will have severe impacts on surface runoff in the valley region. For example, as a result of urban expansion, the surface runoff in the Huangzhong, Xining, and Datong catchments will increase by 4.90–9.01%, 4.25–7.36%, and 2.33–3.95%, respectively. Therefore, we believe that the coupled model can be utilized to evaluate the future UEI on surface runoff in alpine basins. In addition, the local government should pay attention to flood risk prevention, especially in the valley region, and adopt reasonable urban planning with soft and hard adaptation measures to promote the sustainable development of alpine basins under rapid urban expansion.

Authors: Kang Byung Mo , Kim Chang Woo , Lee Suk-Hwan
Published: December 2020

Purpose: Recently, laparoscopic reversal of Hartmann’s colostomy was performed with favorable outcomes by many surgeons. We partially applied the concepts of single-port laparoscopic procedure through the colostomy site to remove intraperitoneal adhesion during initial step of the laparoscopic Hartmann’s reversal. This study aimed to evaluate the feasibility and safety of the laparoscopic reversal of Hartmann’s colostomy with the application of single-port laparoscopic techniques through the colostomy site.Methods: From October 2008 to November 2018, the laparoscopic Hartmann’s reversal was attempted in 20 patients. After colostomy take-downs, the single-port device was installed at the colostomy site and the single-port laparoscopic procedure was performed to remove intraperitoneal adhesions to provide space for additional trocars. After additional trocars were inserted, the descending colon and rectal stump were mobilized, and the colorectal anastomosis was completed. We retrospectively reviewed the medical records and analyzed the data to identify the perioperative complication rates as the primary outcome.Results: Of the 20 patients, 3 patients (15.0%) had open conversions due to severe adhesions. Intraoperative small bowel injuries occurred in 2 patients (10.0%) and these were repaired through the colostomy site. Postoperative complications developed in 4 patients (20.0%) and were managed with medical treatments or wound closures under local anesthesia.Conclusion: The single-port laparoscopic procedure through the colostomy site is sufficiently safe in order to complete the Hartmann’s reversal. We recommend that the colostomy site should be used as the access route into the abdominal cavity for the Hartmann’s reversal.

Published: December 2020

Background

Guidelines recommend that clinicians identify individuals at high cardiometabolic risk and support weight loss in those with overweight or obesity. However, we lack individual level data quantifying the benefits of weight change for individuals to guide consultations in primary care.

Aim

To examine how weight change affects cardiometabolic risk factors, and to facilitate shared decision making between patients and clinicians regarding weight loss.

Design and setting

Observational analysis using data from two trials of referral of individuals with overweight or obesity in primary care to community weight-loss groups.

Method

Linear mixed effects regression modelling examining the association between weight change and change in systolic blood pressure (SBP), diastolic blood pressure (DBP), fasting glucose, glycated haemoglobin (HbA1c), and lipid profile across multiple timepoints (baseline to 24 months). Subgroup analyses examined changes in individuals with hypertension, diabetes, and hyperlipidaemia.

Results

In total, 2041 participants had a mean (standard deviation) age of 50 (SD 13.5) years, mean baseline weight of 90.6 (14.8) kg and mean body mass index (BMI) of 32.7 (SD 4.1) kg/m2. Mean (SD) weight change was −4.3 (SD 6.0) kg. All outcome measures showed statistically significant improvements. Each 1 kg weight loss was associated with 0.4 mmHg reduction in SBP and 0.3 mmHg reduction in DBP, or 0.5 mmHg and 0.4 mmHg/kg respectively in people with hypertension. Each 1 kg weight loss was associated with 0.2 mmol/mol reduction in HbA1c, or 0.6 mmol/mol in people with diabetes. Effects on plasma lipids were negligible.

Conclusion

Weight loss achieved through referral to community weight-loss programmes, which are commonly accessible in primary care, can lead to clinically relevant reductions in BP and glucose regulation, especially in those at highest risk.

O registro das práticas docentes pelo professor de língua portuguesa como processo formativo: um estudo de caso na região do Vale do Caí – RS
Authors: Böttcher Cristiane , Carpes Camargo Edson
Published: December 2020

Faz parte do cotidiano dos professores de Língua Portuguesa ocupar a posição de instigadores de produções textuais, estimulando a imaginação e a criticidade de seus/suas alunos/as. Neste cenário, este estudo tem por objetivo refletir se os registros estão sendo feitos e, caso estejam, por qual motivo são tão pouco divulgados. Diante disso, optou-se como percurso metodológico pela pesquisa qualitativa com aporte na produção de narrativas autobiográficas, conforme menciona Schütze (1983). Os participantes do estudo são professores de Língua Portuguesa que possuem formação na área e atuam em escolas de educação básica. Os resultados apontaram que os registros das práticas ocorrem mais por uma questão burocrática - com registro nos cadernos de presença - do que movidos por questões que possam aprimorar e qualificar a prática docente.

Published: December 2020

The World Wide Web is a large, wealthy, and accessible information system whose users are increasing rapidly nowadays. To retrieve information from the web as per users’ requests, search engines are built to access web pages. As search engine systems play a significant role in cybernetics, telecommunication, and physics, many efforts were made to enhance their capacity.However, most of the data contained on the web are unmanaged, making it impossible to access the entire network at once by current search engine system mechanisms. Web Crawler, therefore, is a critical part of search
engines to navigate and download full texts of the web pages. Web crawlers may also be applied to detect missing links and for community detection in complex networks and cybernetic systems. However, template-based crawling techniques could not handle the layout diversity of objects from web pages. In this paper, a web crawler module was designed and implemented, attempted to extract article-like contents from 495 websites. It uses a machine learning approach with visual cues, trivial HTML, and text-based features to filter out clutters. The outcomes are promising for extracting article-like contents from websites, contributing to the search engine systems development and future research gears towards proposing higher performance systems.

This paper focuses on the theology of the philosopher Simone Weil, analysing the inherent struggle between the notion of the impersonal and the personal God, strongly present in her writings. The first part of the paper focuses on Weil’s point de d.part, in which she maintained that the relationship between humanity and God should not be a personal one. This premise is rooted in Weil’s apophatic spirituality. It proceeds by giving an analysis of the dynamics in the notion of the impersonal God, juxtaposing it against the mystical experiences of Simone Weil herself. Weil’s spiritual journey led her to integrating the two polarities. The second part of the paper focuses on an integrative model that can be derived from Weil’s writings through her “spirituality of contradiction.” In the face of the struggle, Weil believed in the importance of staying in the uncomfortable space of the unknown, without rejecting either polarity. The paper concludes by demonstrating the relevance of this integrative model to contemporary society as a vehicle of integrity in the path towards wholeness.
Phenomenological Spirituality and its Relationship to Religion
Authors: DeRoo Neal
Published: December 2020

This paper develops a phenomenological account of spirituality that can help us think more broadly and deeply about religion and its role in our lives. It begins by explaining spirituality as a supra-subjective force that shapes a subject’s intuitive engagement with the world (Section I). Then, it shows that such a spirituality is affective in (and affected by) cultural expression (Section II), by way of historically situated institutions or traditions [Stiftungen] (Section III). The last step of the paper will be to connect this account of spirituality to our understanding of religion by articulating four distinct levels of phenomenological analysis that will have emerged in the discussion of spirituality and showing that each of these levels must be accounted for in a distinct way if we want to offer a full-fledged philosophy of religion (Section IV). In so doing, we will see that this account of spirituality potentially helps us see a broader range of things that could count as “religious,” in part by helping us see that religion is a particular mode of expressing the spirituality that operates as the deepest motivating impulse driving our lives.

Authors: K Joshi Nirali , Parasmani Parasmani , Shukla Mukesh I.
Published: December 2020

BACKGROUND-Most of the lower abdominal surgeries are performed under spinal anaesthesia which is a popular technique using hyperbaric local anaesthetic solutions such as 0.5% Bupivacaine. The advantages are simplicity of technique, rapid onset of action and reliability in producing uniform sensory and motor blockade. Main disadvantage of using plain local anaesthetic agent arelimited duration of action and lack of longer postoperative analgesia.To overcome this problem, administration of different adjuvant in local anaesthetic is an excellent technique.
AIMS-To compare the effect of adding Clonidine and Dexmedetomidine to Bupivacaine for neuraxial block.
METHODS-This study was be conducted after the approval of institutional ethical committee. It is a prospective study in which 75 selected patients who were posted for lower abdominal surgeries were randomly allotted into three groups.Group B -Inj.0.5% Heavy Bupivacaine 3.2cc(16 mg) + Inj. Normal saline Group C -Inj.0.5% Heavy Bupivacaine 3.2cc(16 mg) + Inj.Clonidine 30 mcgGroup D -Inj.0.5% Heavy Bupivacaine 3.2cc(16 mg) + Inj.Dexmedetomidine 3 mcg, Total volume injected in all group was 3.5 ml.The end of drug injection was taken as zero time. Onset, duration of sensory blockade, duration of motor blockade was noted.
RESULTS –prolonged sensory and motor blockage and superior post-operative analgesia was observed in group D.
CONCLUSION- Addition of Dexmeditomidine 3 mcg is significantly more effective than plain 0.5% Bupivacaine or when Clonidine 30mcg was used as adjuvant, for prolongation of sensory and motor blockage and post-operative analgesia.

Shivering during regional anesthesia is a common problem and is distressing for patients with variety of complications. Therefore this study was conducted to compare the efficacy, potency, hemodynamic effects and side effects of tramadol with that of meperidine for the control of shivering during Spinal Anaesthesia. Sixty patients of ASA physical status I or II, aged 18 to 65 years, undergoing routine surgery under spinal anaesthesia and developed shivering intraoperatively were randomly allocated to receive 0.5 mg/kg meperidine intravenously (Group A, n=30) or 0.5 mg/kg tramadol intravenously (Group B, n=30). Treatment that stopped shivering was considered to have been successful. The response rate was 100 % in both the groups. The time that elapsed from treatment to the time shivering ceased was 5.37±2.20 minutes for meperidine group and 5.87±2.92 minutes for tramadol group (p>0.05). The number of patients who assessed treatment efficacy as no, partial or marked improvement was 0, 2 and 28 for meperidine group and 0, 3 and 27 for tramadol group (p>0.05). Only two patients receiving meperidine developed pruritis and both the grops were similar in terms of Haemodynamic response. The result of this study concluded that tramadol (0.5 mg/kg) is as effective as meperidine (0.5 mg/kg) for treating post anaesthetic shivering with high safety profile.
