Authors: Zhou Zike , Wang Yongping , Teng Haowei , Yang Hao , Liu Aiju , Li Menghong , Niu Xiaoyin
Published: June 2020

In this study, the concentrations of seven heavy metals (Cr, Ni, Cu, Zn, As, Hg, and Pb) and Pb isotope in a sediment core from the Shuanglong reservoir, Southwestern China, were investigated. Based on the constant rate of supply (CRS) model, the age span of a 60 cm sediment sample was determined to range from the years 1944 to 2015. Combined with chronology and heavy metal content, the evolution of the sources and pollution levels of heavy metals showed a changing trend composed of various stages. The sources of heavy metals transitioned from natural origins in 1944–1964 to industrial origins in 1965–2004. The subsequent reduction in heavy metal content was mainly due to the vigorous implementation of environmental protection policies from 2005 to 2012. In recent years (2013–2015), the heavy metal content has increased due to frequent human activity. Principal component analysis (PCA), correlation analysis, and the coefficient of variation (CV) analysis indicated that Cr, Ni, Cu, Zn, and As were derived from natural processes, Pb mainly came from automobile manufacturing, and Hg was mainly from industrial sources. The values of the geo-accumulation index (Ig), single pollution index (Pi), and single potential ecological risk index (Er) showed that the contamination of Hg and Pb was slight to moderate. Moreover, the values of the potential ecological risk index (RI), pollution load index (PLI), and Nemerow index (PN) indicated that the Shuanglong reservoir is under low ecological risk.

Published: June 2020

Sediment connectivity is considered a powerful geomorphic indicator for defining the most sensitive areas to geomorphological modifications in a fluvial catchment (hotspots). This encourages the development of methods and models for its assessment, to investigate the interrelation of the various phenomena that occur in a river basin (landslides, floods, etc.). This work explores the potential connection of the processes in flood dynamics, by focusing on induced flood hazard, in order to evaluate the applicability of sediment connectivity to flood monitoring. By applying the recently developed sediment flow connectivity index (SCI) computation method to the Severn River basin, in UK, recurrently affected by floods, we investigate the agreement between the hotspot areas (described by the index) and the areas recurrently flooded (as mapped by aerial photography, satellite imagery and hydrodynamic modelling). Qualitative and quantitative approaches are used for the analysis of past (March 2007 and January 2010) as well as predicted (with return periods of 200 and 500 years) flood events. The results show a good correspondence of areas of high sediment connectivity with flood occurrence. Moreover, the detection performance of the SCI is slightly better than that of a simple flow accumulation map, confirming the importance of the initial mapping of sediment availability and mobility. This experiment extends the direct applicability of the SCI from fluvial analysis to flood monitoring, thus opening interesting future scenarios.

Application of GWO-ELM Model to Prediction of Caojiatuo Landslide Displacement in the Three Gorge Reservoir Area
Authors: Zhang Liguo , Chen Xinquan , Zhang Yonggang , Wu Fuwei , Chen Fei , Wang Weiting , Guo Fei
Published: June 2020

In order to establish an effective early warning system for landslide disasters, accurate landslide displacement prediction is the core. In this paper, a typical step-wise-characterized landslide (Caojiatuo landslide) in the Three Gorges Reservoir (TGR) area is selected, and a displacement prediction model of Extreme Learning Machine with Gray Wolf Optimization (GWO-ELM model) is proposed. By analyzing the monitoring data of landslide displacement, the time series of landslide displacement is decomposed into trend displacement and periodic displacement by using the moving average method. First, the trend displacement is fitted by the cubic polynomial with a robust weighted least square method. Then, combining with the internal evolution rule and the external influencing factors, it is concluded that the main external trigger factors of the periodic displacement are the changes of precipitation and water level in the reservoir area. Gray relational degree (GRG) analysis method is used to screen out the main influencing factors of landslide periodic displacement. With these factors as input items, the GWO-ELM model is used to predict the periodic displacement of the landslide. The outcomes are compared with the nonoptimized ELM model. The results show that, combined with the advantages of the GWO algorithm, such as few adjusting parameters and strong global search ability, the GWO-ELM model can effectively learn the change characteristics of data and has a better and relatively stable prediction accuracy.

Measuring the Transaction Costs of Historical Shifts to Informal Drought Management Institutions in Italy
Authors: Loch Adam , Santato Silvia , Pérez-Blanco C. Dionisio , Mysiak Jaroslav
Published: June 2020

Coase shows how costly resources are (re)allocated via costly institutions, and that transaction costs must therefore be positive. However, Coase did not elaborate on transitions between institutions which incur positive transaction costs that are characterized by numerous institutional complementarities; that is, feedback loops that inform the need for, and pathways toward, institutional change. Economic investigations of complementary modes of (re)allocation are rarely undertaken, let alone studies of transitions between modes. However, modes of (re)allocation that achieve similar results at less cost are generally viewed as having production-raising value. This paper measures the costs of transitioning drought management institutions in Italy toward informal, participatory, and consensus-based approaches during several recent drought events. The chosen model is Drought Steering Committees, which offer a substitute for current formal (less flexible) planning approaches, and where lower transaction costs that are associated with the transition are inferred. Our results highlight the relevance of empirical assessments of ‘costly’ transitions based on a historical study of transaction costs, as well as supporting previous works that highlight the value of contextual analysis in economic studies, in order to identify the benefits of institutional investment.
Non-Stationary Flood Frequency Analysis Using Cubic B-Spline-Based GAMLSS Model
Authors: Qu Chunlai , Li Jing , Yan Lei , Yan Pengtao , Cheng Fang , Lu Dongyang
Published: June 2020

Under changing environments, the most widely used non-stationary flood frequency analysis (NFFA) method is the generalized additive models for location, scale and shape (GAMLSS) model. However, the model structure of the GAMLSS model is relatively complex due to the large number of statistical parameters, and the relationship between statistical parameters and covariates is assumed to be unchanged in future, which may be unreasonable. In recent years, nonparametric methods have received increasing attention in the field of NFFA. Among them, the linear quantile regression (QR-L) model and the non-linear quantile regression model of cubic B-spline (QR-CB) have been introduced into NFFA studies because they do not need to determine statistical parameters and consider the relationship between statistical parameters and covariates. However, these two quantile regression models have difficulties in estimating non-stationary design flood, since the trend of the established model must be extrapolated infinitely to estimate design flood. Besides, the number of available observations becomes scarcer when estimating design values corresponding to higher return periods, leading to unreasonable and inaccurate design values. In this study, we attempt to propose a cubic B-spline-based GAMLSS model (GAMLSS-CB) for NFFA. In the GAMLSS-CB model, the relationship between statistical parameters and covariates is fitted by the cubic B-spline under the GAMLSS model framework. We also compare the performance of different non-stationary models, namely the QR-L, QR-CB, and GAMLSS-CB models. Finally, based on the optimal non-stationary model, the non-stationary design flood values are estimated using the average design life level method (ADLL). The annual maximum flood series of four stations in the Weihe River basin and the Pearl River basin are taken as examples. The results show that the GAMLSS-CB model displays the best model performance compared with the QR-L and QR-CB models. Moreover, it is feasible to estimate design flood values based on the GAMLSS-CB model using the ADLL method, while the estimation of design flood based on the quantile regression model requires further studies.

Published: June 2020

BTEX (benzene, toluene, ethylbenzene, and the different xylene isomers), known for carcinogenic and neurotoxic effects, are common environmental contaminants. The first step for the development of the bioremediation technologies is the detection of intense microbial degradation in contaminated waters in the quest for the most active bacterial strains. This requires the multispecies analysis for BTEX metabolites which are considered as markers of microbial degradation. A direct (50 µL injection) HPLC–electrospray MS/MS analytical method was developed for the simultaneous analysis of 11 BTEX metabolites (o-, m-, p-toluic, salicylic, benzoate, benzyl, and phenyl succinic acids, 2-(1-phenylethyl)-, 2-(2-methylbenzyl), and 2-(3-methylbenzyl)-, 2-(4-methyl benzyl)-succinic acids) in bacterial cultures and ground waters down to 0.1 ng/mL. The optimization of the chromatographic conditions allowed for the resolution of position isomers of toluic and methylbenzyl-succinic acids. The stability of the analytes during sample storage tested in different conditions showed the instability of some of them when stored at room temperature. The feasibility of the method was demonstrated by the detection of all the investigated metabolites in a water sample of a deep aquifer hosting natural gas storage. A model laboratory study emphasized the importance of 2-(2-methylbenzyl)-succinic acid as a marker of anaerobic microbial degradation.
Water from the Perspective of Education for Sustainable Development: An Exploratory Study in the Spanish Secondary Education Curriculum
Authors: Martínez-Borreguero Guadalupe , Maestre-Jiménez Jesús , Mateos-Núñez Milagros , Naranjo-Correa Francisco Luis
Published: June 2020

Current educational curricula in Spain contain few references to sustainability topics, so there is insufficient coverage of these issues in the classroom. Notably, there is a lack of reference to the concept of water from a sustainable perspective. The key aim of this study was to analyze the presence of the concept of water in the curriculum that regulates secondary education in Spain using a previously established system of categories. An exploratory and descriptive research methodology was followed, in which we carried out a qualitative lexicographical analysis of the concept of water in the Spanish secondary education curriculum. An analysis of the cognitive demand required of students to learn about water, according to Bloom’s taxonomy, was also conducted. The results show that the concept of water appears moderately in the curriculum focusing on some aspects of Sustainable Development. Likewise, the analysis of the cognitive demand required of students for learning about water reveals that lower levels of knowledge and comprehension predominate based on Bloom’s taxonomy. We consider that teaching water from a sustainable perspective can generate in students awareness and values about nature and the environment, knowledge that contributes to sensible use of water and involvement for sustainable development.
Design Parameters for the Early Development Phase of Battery Electric Vehicles
Authors: Nicoletti Lorenzo , Mayer Sebastian , Brönner Matthias , Schockenhoff Ferdinand , Lienkamp Markus
Published: June 2020

The derivation of a battery electric vehicle (BEV) architecture represents a challenging task for car manufacturers. For the early development of combustion engine architectures, the required design parameters can be derived from the analysis of previously-built model series. Regarding BEV architectures, the manufacturers do not yet have a reference series of vehicles on the basis of which they can derive the essential design parameters. Therefore, these parameters are mainly estimated at high cost in the early development phase. To avoid cost-intensive changes in the further course of development it is crucial to choose the right set of design parameters. For this reason, the aim of this paper is the identification of a minimum set of design parameters, derived from the current state-of-the-art of vehicle development by a structured literature comparison. We group the results according to our definition of vehicle architecture and discuss each identified parameter to explain its relevance. The sum of all parameters presented in this paper builds a minimum set of design parameters, which can be employed as a guideline for the definition of BEV architectures in the early development stage.
Nausea and vomiting in pregnancy is not just ‘morning sickness’: data from a prospective cohort study in the UK
Authors: Gadsby Roger , Ivanova Diana , Trevelyan Emma , Hutton Jane L , Johnson Sarah
Published: June 2020

Background

Nausea and vomiting in pregnancy is usually called ‘morning sickness’. This is felt by sufferers to trivialise the condition. Symptoms have been described as occurring both before and after noon, but daily symptom patterns have not been clearly described and statistically modelled to enable the term ‘morning sickness’ to be accurately analysed.

Aim

To describe the daily variation in nausea and vomiting symptoms during early pregnancy in a group of sufferers.

Design and setting

A prospective cohort study of females recruited from 15 May 2014 to 17 February 2017 by Swiss Precision Diagnostics (SPD) Development Company Limited, which was researching hormone levels in early pregnancy and extended its study to include the description of pregnancy symptoms.

Method

Daily symptom diaries of nausea and vomiting were kept by females who were trying to conceive. They also provided daily urine samples, which when analysed enabled the date of ovulation to be determined. Data from 256 females who conceived during the first month of the study are included in this article. Daily symptom patterns and changes in daily patterns by week of pregnancy were modelled. Functional data analysis was used to produce estimated symptom probability functions.

Results

There was a peak probability of nausea in the morning, a lower but sustained probability of nausea throughout the day, and a slight peak in the evening. Vomiting had a defined peak incidence in the morning.

Conclusion

Referring to nausea and vomiting in pregnancy as simply ‘morning sickness’ is inaccurate, simplistic, and therefore unhelpful.

Published: June 2020

O propósito deste artigo é, a partir da noção de subjetividade pensada por Émile Benveniste, abordar a leitura como um ato enunciativo. A reflexão teórica construída, com base nos artigos de Benveniste e em estudiosos da teoria da enunciação, como Flores, Barbisan, Teixeira e Normand, permite associar a leitura ao ato do sujeito que, de maneira individual, mobiliza a língua para enunciar-se. A subjetividade, na atividade da leitura, apresenta-se como a capacidade do leitor/locutor de apropriar-se da língua e atualizá-la, reconstituindo sentidos e posicionando-se no discurso como sujeito que diz eu.

Published: June 2020

The phase composition of the oxide films on the surface of the Fe-Cr-Al system coatings is studied using glancing angle X-ray diffraction. It is shown that at 900 °С the formed oxide films consist of αAlO and (FeCr)O, to which FeAlO oxide is added during long-term exposure. An increase in temperature to 1100 °C intensifies the growth of oxide films, and an increase in the aluminum content ensures a stable growth of αAlO and FeAlO oxides. When the aluminum content in the coating is more than 10 at. % at large exposure times, metastable alumina δAlO is formed, the formation of which is associated with a decrease in the concentration of chromium in thin surface layers.

The quick death of a lake: human impact on Lake Tresssee (N Germany) during the last 6000 years – an approach using pollen, Cladocera and sedimentology
Authors: Stolz Christian , Pidek Irena A. , Suchora Magdalena
Published: June 2020

Human-induced fluctuation of lake levels has been a common phenomenon in Europe since Neolithic times. At present, Lake Tresssee is a eutrophic lake covering less than 5 ha in northern Germany, but its sudden shrinking from ~125 ha before 1800 is considered a consequence of anthropogenic lowering of the lake level. We investigated the history of anthropogenic vegetation changes and water level fluctuations by multiproxy studies of a 4 m core from the former lake area. Our analyses of pollen and Cladocera subfossil, chemistry and sedimentological features yielded important conclusions about interactions between land-use history and climate impacts on the lake and its surroundings. The results indicate that the highest lake level persisted until the Late Atlantic. Since the Subboreal there have been several fluctuations, mostly in consequence of climate impacts. Later, different phases of sediment input to the lake from tributary streams and probably also from aeolian processes from an adjacent dune field were observed. At ~2800 BC the sedimentation rate decreased in consequence of fluvial impacts, as the lake basin was nearly filled up with deposits. As a result of greater human impacts, from the Early Bronze Age the macrophyte zone expanded in the lake, the oxygen content of the water continuously decreased, and heathlands developed in the surroundings. From the Late Iron Age and in the Early Medieval, pollutants probably from ironworks are detectable by geochemical analyses in the corresponding segments. In the pollen diagram the Migration Period is clearly visible, but the suggested radiocarbon date is younger than in Lake Belau in the neighboring region of Schleswig-Holstein. Most probably our pollen diagram did not register the absolute maximum values of Fagus related to the Migration Period. From the Early Medieval a clear phase of resettlement occurs. Since the Early Modern period, the lake level has shrunk rapidly in consequence of historically documented human activity.

Published: June 2020

Objective: The purpose of our research was to assess characteristics of immune regulation in petrochemical workers suffering from cardiovascular diseases (CVD). Materials and methods: Our sample was divided into two groups: an observation group consisting of 115 people with CVD and a reference group of 56 people. Blood benzene was assayed by gas chromatography. Cellular phagocytosis was examined using formalinized sheep erythrocytes. The IgG content specific to benzene was measured using the allergosorbent test. CD-lymphocytes were phenotyped on a flow cytometer via membrane immune fluorescence and applying a panel of labeled monoclonal antibodies to membrane CD-receptors. Expression of TNFR, p53, Bcl-2, and bax was determined by applying relevant monoclonal antibodies. We used the enzyme-linked immunosorbent assay (ELISA) to determine total IgG, CA 19-9, prostate-specific antigen (PSA), interleukin-6, and VEGF. Statistical data analysis was performed using techniques of descriptive statistics and sample comparison. Intergroup differences were considered statistically significant at р≤0.05. Results: Chemical analytical tests revealed an excess benzene burden in the test group against the reference one. Immunoassays showed higher cellular phagocytic activity. We detected significant changes in CD-immunogram parameters such as increased concentrations of CD16+ effector cells, activation of Т-suppressors lymphocytes CD127-, an increase in Annexin V-FITC+7ADD-negative cells, TNFR, p53, bcl-2, bax, as well as the deficiency of CD19+, CD25+, CD95+ lymphocytes both against the reference group and physiological standards. We also determined an increase in total and benzene-specific sensibilization of the body, elevated concentrations of tumor markers CA 19-9 and PSA, interleukin-6, and the growth factor of vessels endothelium VEGF. All these changes characterized the features of immune homeostasis indicators and were responsible for pathogenesis and development of cardiovascular diseases. Conclusions: Significant associations of immunologic parameters in the form of functional disorders in programmed cells death with simultaneous activation of specific sensibilization processes create specific immunologic status of petrochemical workers with cardiovascular diseases in their medical history.

Published: June 2020

Background: Mandibular fractures are the most common type of facial fractures in the adult population, accounting for 36%-59% of all maxillofacial injuries and their treatment is one of the most frequent forms of therapy provided by maxillofacial surgeons. The objective of the study was to compare the outcome of transosseous wiring and miniplates in the management of mandibular parasymphyseal fractures in terms of infection and malocclusion.

Material and Methods: This randomized control trial was carried out at Oral and Maxillofacial Department, Ayub Medical College/ Ayub Teaching Hospital Abbottabad. A total of 124 patients were randomly allocated into two groups by lottery method. Patients in group A were subjected to transosseous wiring with maxilla-mandibular fixation. Patients in group B underwent miniplate fixation method. Post-operative wound in­fection and malocclusion findings at 6 weeks were recorded.

Results: Frequency of post-operative infection and malocclusion at 6 weeks of surgery was slightly more but statistically non-significant in patients of group A undergoing Transosseous wiring method as compared to group B patients experiencing Miniplate technique.

Conclusions: Miniplate osteosynthesis causes slightly less post-operative morbidity in terms of infection and malocclusion as compared to transosseous wiring for the management of mandibular parasymphyseal fractures.
