Does ESG Affect the Stability of Dividend Policies in Europe?
Authors: Verga Matos Pedro , Barros Victor , Miranda Sarmento Joaquim
Published: October 2020

Sustainability has become a significant issue for firms and investors throughout the world, although it cannot be attained if policies impact the stability of firms’ dividend policies. In this paper, we use data from the Stoxx Euro 600 firms from 2000 to 2019 and the ESG (environmental, social and governance) scores from Thomson Reuters to assess the relationship between ESG responsibility performances and the firm’s dividend policy. The results indicate that more sustainable firms exhibit a more stable dividend payout. This result is also valid when the ESG pillars are analysed, specifically, the environmental and governance pillars. The findings further suggest that higher ESG scores reveal better long-term alignment with shareholders and other stakeholders due to more proportionally stable profit sharing.
Creating Shared Values by Integrating UN Sustainable Development Goals in Corporate Communication—The Case of Apparel Retail
Authors: Olofsson Linnea , Mark-Herbert Cecilia
Published: October 2020

The textile and apparel industry, while endowed with enormous potential related to the development of countries, is continuously drawing attention to its negative sustainability impacts along their value chains. While apparel retail has been an early adopter to integrate the Sustainable Development Goals (SDGs) into sustainability reports, critics point to the fact that linking sustainability activities to the SDGs is not enough, and cherry-picking low hanging fruit goals is insufficient. To address this potential discrepancy between action and communication, the aim of this study is to explain the perceived value of SDG integration in sustainability reporting in apparel retail. A comparative case study has been conducted of two Swedish apparel retail companies, Lindex and Filippa K, where six sustainability reports from 2015–2017 were reviewed. Empirical findings suggest that there is a correlation between SDG integration, communication maturity, and SDG contribution. The study points to the guiding role the SDGs may have to expand the scope of corporate impact and value in sustainability communication.

Published: October 2020

The cost, time and scope of a construction project are key parameters for its success. Thus, predicting these indices is indispensable. Correct and accurate prediction of cost throughout the progress of a project gives project managers the chance to identify projects that need revision in their schedules in order to result in the maximum benefit. The aim of this study is to minimize the shortcomings of the Earned Value Management (EVM) method using an Artificial Neural Network (ANN) and multiple regression analysis in order to predict project cost indices more precisely. A total of 50 road construction projects in Fars Province, Iran, were selected for analysis in this research. An ANN model was used to predict the projects’ cost performance indices, thereby creating a more accurate symmetry between the predicted and actual cost by considering factors that influence project success. The input data of the ANN model were analysed in MATLAB software. A multiple regression model was also used as another analytical tool to validate the outcome of the ANN. The results showed that the ANN model resulted in a lower Mean Squared Error (MSE) and a greater correlation coefficient than both the traditional EVM model and the multiple regression model.
Joint Entity-Relation Extraction via Improved Graph Attention Networks
Authors: Lai Qinghan , Zhou Zihan , Liu Song
Published: October 2020

Joint named entity recognition and relation extraction is an essential natural language processing task that aims to identify entities and extract the corresponding relations in an end-to-end manner. At present, compared with the named entity recognition task, the relation extraction task performs poorly on complex text. To solve this problem, we proposed a novel joint model named extracting Entity-Relations viaImproved Graph Attention networks (ERIGAT), which enhances the ability of the relation extraction task. In our proposed model, we introduced the graph attention network to extract entities and relations after graph embedding based on constructing symmetry relations. To mitigate the over-smoothing problem of graph convolutional networks, inspired by matrix factorization, we improved the graph attention network by designing a new multi-head attention mechanism and sharing attention parameters. To enhance the model robustness, we adopted the adversarial training to generate adversarial samples for training by adding tiny perturbations. Comparing with typical baseline models, we comprehensively evaluated our model by conducting experiments on an open domain dataset (CoNLL04) and a medical domain dataset (ADE). The experimental results demonstrate the effectiveness of ERIGAT in extracting entity and relation information.
Vibrational Circular Dichroism Detects Symmetry Breaking due to Conformational Mobility in C2-Symmetry Chiral Molecules and Provides Further Insight into Inter-Chromophoric Interactions
Authors: Mazzeo Giuseppe , Abbate Sergio , Boiadjiev Stefan E. , Lightner David A. , Longhi Giovanna
Published: October 2020

Bicyclo[3.3.1]nonane-2,6-dione (1) and bicyclo[3.3.1]nona-3,7-diene-2,6-dione (2) have been examined by vibrational circular dichroism (VCD), which, as for most C2-symmetric systems, exhibits strong VCD signals. In the case of 2, VCD signals are stronger and sharper with several bisignate doublets; for 1, signals are less intense and broader. The VCD and IR spectra are excellently predicted by DFT calculations: only one conformer is present for 2, while for 1, three main conformers, related through concerted skeleton torsional motions are present (two of them being interchanged by C2-rotation). The VCD spectrum shows specific features for the different conformers, such that correct population factors are crucial for reproducing experimental data. Also, the TD-DFT prediction of ECD (electronic circular dichroism) spectra is good. By comparing the spectroscopic signature of the two molecules (both VCD and ECD) and by careful analysis of the theoretical results, the role of the C=C double bond in compound (2) is evidenced. The double bond contributes toward enhancing the CD response both electronically and vibrationally.

Published: October 2020

The task of dialogue generation has attracted increasing attention due to its diverse downstream applications, such as question-answering systems and chatbots. Recently, the deep neural network (DNN)-based dialogue generation models have achieved superior performance against conventional models utilizing statistical machine learning methods. However, despite that an enormous number of state-of-the-art DNN-based models have been proposed, there lacks detailed empirical comparative analysis for them on the open Chinese corpus. As a result, relevant researchers and engineers might find it hard to get an intuitive understanding of the current research progress. To address this challenge, we conducted an empirical study for state-of-the-art DNN-based dialogue generation models in various Chinese corpora. Specifically, extensive experiments were performed on several well-known single-turn and multi-turn dialogue corpora, including KdConv, Weibo, and Douban, to evaluate a wide range of dialogue generation models that are based on the symmetrical architecture of Seq2Seq, RNNSearch, transformer, generative adversarial nets, and reinforcement learning respectively. Moreover, we paid special attention to the prevalent pre-trained model for the quality of dialogue generation. Their performances were evaluated by four widely-used metrics in this area: BLEU, pseudo, distinct, and rouge. Finally, we report a case study to show example responses generated by these models separately.

Published: October 2020

Magnetorheological (MR) regenerative suspension system can not only achieve excellent comprehensive suspension performance but also effectively recover and utilize vibration potential energy, which has been a research hotspot in the field of vehicle engineering. In this paper, for the 1/4 vehicle’s MR regenerative suspension system parallel with a tubular permanent magnet linear motor (TPMLM), the dynamic model of the MR semi-active suspension system and the TPMLM finite element model are established separately to form a joint simulation platform. The simulation analysis of the comprehensive suspension performance and regeneration performance under different road excitations is performed. The results show that installing TPMLM does not change the natural resonance frequency of the suspension system, which ensures good driving comfort and handling stability. At the same time, it has considerable regeneration power. This research can provide a reference for the stability analysis and popularization of the vehicle’s MR regenerative suspension system.
Sediment Morphology and the Flow Velocity Field in a Gully Pot: An Experimental Study
Authors: Rietveld Matthijs , de Rijke Demi , Langeveld Jeroen , Clemens Francois
Published: October 2020

Urban runoff (re)mobilises solids present on the street surface and transport them to urban drainage systems. The solids reduce the hydraulic capacity of the drainage system due to sedimentation and on the quality of receiving water bodies due to discharges via outfalls and combined sewer overflows (CSOs) of solids and associated pollutants. To reduce these impacts, gully pots, the entry points of the drainage system, are typically equipped with a sand trap, which acts as a small settling tank to remove suspended solids. This study presents data obtained using Particle Image Velocimetry (PIV) and Laser Doppler Anemometry (LDA) measurements in a scale 1:1 gully to quantify the relation between parameters such as the gully pot geometry, discharge, sand trap depth, and sediment bed level on the flow field and subsequently the settling and erosion processes. The results show that the dynamics of the morphology of the sediment bed influences the flow pattern and the removal efficiency in a significant manner, prohibiting the conceptualization of a gully pot as a completely mixed reactor. Resuspension is initiated by the combination of both high turbulent fluctuations and high mean flow, which is present when a substantial bed level is present. In case of low bed levels, the overlaying water protects the sediment bed from erosion.

Published: October 2020

Alternative new technologies are urgently needed to overcome the rapidly increasing global water scarcity. Atmospheric dew water is a potential source of potable water, as the earth’s atmosphere contains billions of tons of fresh water (98% in a vapor state). The atmospheric water generator (AWG) converts water vapor into liquid water and is a promising solution for water scarcity. We provide the first comprehensive analysis of the chemical profiles of water produced for several months by an AWG in the city of Tel Aviv, Israel. Metals, inorganic ions, volatile organic compounds (VOCs), and semi-VOCs were analyzed in the dew water. The main elements found were ammonium, calcium, sulfate, and nitrate. Location of the sampling site in an urban residential area, between major traffic routes, likely affected the chemical composition of the produced dew water. Nevertheless, the produced water nearly always (day and night in different seasons) met the WHO and Israeli drinking water standards. Thus, even in a highly developed urban environment, the AWG offers an excellent alternative source of safe drinking water throughout the year.
Influence of Warmer and Drier Environmental Conditions on Species-Specific Stem Circumference Dynamics and Water Status of Conifers in Submontane Zone of Central Slovakia
Authors: Leštianska Adriana , Fleischer Peter , Merganičová Katarína , Fleischer Peter , Střelcová Katarína
Published: October 2020

The frequency and intensity of droughts and heatwaves in Europe with notable impact on forest growth are expected to increase due to climate change. Coniferous stands planted outside the natural habitats of species belong to the most threatened forests. In this study, we assess stem circumference response of coniferous species (Larix decidua and Abies alba) to environmental conditions during the years 2015–2019. The study was performed in Arboretum in Zvolen (ca. 300 m a.s.l., Central Slovakia) characterised by a warmer and drier climate when compared to their natural habitats (located above 900 m a.s.l.), where they originated from. Seasonal radial variation, tree water deficit (ΔW), and maximum daily shrinkage (MDS) were derived from the records obtained from band dendrometers installed on five mature trees per species. Monitored species exhibited remarkably different growth patterns under highly above normal temperatures and uneven precipitation distribution. The magnitudes of reversible circumference changes (ΔW, MDS) were species-specific and strongly correlated with environmental factors. The wavelet analysis identified species-specific vulnerability to drought indicated by pronounced diurnal stem variation periodicity in rainless periods. L. decidua exhibited more strained stem water status and higher sensitivity to environmental conditions than A. alba. Tree water deficit and maximum daily shrinkage were found appropriate characteristics to compare water status of different tree species.
The Economic Impact of Drought on the Irrigated Crops in the Segura River Basin
Authors: Redondo-Orts José Alberto , López-Ortiz María Inmaculada
Published: October 2020

Throughout history, the Segura River Basin, located in the south-east of the Iberian Peninsula, has suffered from countless drought periods. They have largely been managed as occasional episodes of crisis through the reduction of the resources applied or the mobilisation of extraordinary resources. Recently, the phenomena of drought and water scarcity have been incorporated into Spain’s national hydrological plan. This has given rise to an improvement in their diagnosis and management and enables us to learn about how climate change affects their frequency and intensity. Agriculture is highly relevant in the basin, comprising mainly irrigated crops that represent more than 80% of total demand for a net area of more than 260,000 ha. There is an undeniable connection between this sector and the availability of water and in periods of drought, such as the recent episode in the Segura River Basin (drought declaration in the territorial area of the Segura River Basin through Royal Decree 356/2015 of 8 May), the reduction in the availability of water generates a significant impact on the agricultural sector. Therefore, by analysing the production value and net margin generated in the agri-food systems, both the values established in the 2015/21 Hydrological Plan and those estimated in the drought period 2015–2019, we seek to assess the economic impacts generated, as knowing the direct effect on the agricultural sector will enable us to quantify the opportunity cost resulting from not being able to apply 100% of the resources demanded.
Molecular Methods as Potential Tools in Ecohydrological Studies on Emerging Contaminants in Freshwater Ecosystems
Authors: Mierzejewska Elzbieta , Urbaniak Magdalena
Published: October 2020

Contaminants of emerging concern (CECs) present a threat to the functioning of freshwater ecosystems. Their spread in the environment can affect both plant and animal health. Ecohydrology serves as a solution for assessment approaches (i.e., threat identification, ecotoxicological assessment, and cause–effect relationship analysis) and solution approaches (i.e., the elaboration of nature-based solutions: NBSs), mitigating the toxic effect of CECs. However, the wide array of potential molecular analyses are not fully exploited in ecohydrological research. Although the number of publications considering the application of molecular tools in freshwater studies has been steadily growing, no paper has reviewed the most prominent studies on the potential use of molecular technologies in ecohydrology. Therefore, the present article examines the role of molecular methods and novel omics technologies as essential tools in the ecohydrological approach to CECs management in freshwater ecosystems. It considers DNA, RNA and protein-level analyses intended to provide an overall view on the response of organisms to stress factors. This is compliant with the principles of ecohydrology, which emphasize the importance of multiple indicator measurements and correlation analysis in order to determine the effects of contaminants, their interaction with other environmental factors and their removal using NBS in freshwater ecosystems.
Wastewater Management: Bibliometric Analysis of Scientific Literature
Authors: Durán-Sánchez Amador , Álvarez-García José , González-Vázquez Encarnación , Del Río-Rama María de la Cruz
Published: October 2020

Two of the greatest challenges that threaten sustainable development are the water supply crisis together with the control of water resources pollution. The United Nations recognises that the right to safe drinking water and sanitation is an essential right, and states are called upon to intensify their efforts to provide the entire population with affordable access to safe drinking water. However, due to population growth and climate change, water resources are under great pressure, producing millions of cubic metres of wastewater. Due to the near impossibility of increasing water supply in a natural way, the importance of wastewater management as a method has grown in recent years, which, although it is not to increase the amount of this resource, but to facilitate its successive use before its final return to the sea. The objective of this article is to carry out a bibliometric analysis regarding the production and impact of the scientific research related to wastewater management indexed in the WoS and Scopus databases. The purpose is to know key aspects such as the progression of production over the years, maturity in research, coverage of the subject, identifying the most discussed topics and therefore identifying the gaps, the most relevant authors and the core of journals through which knowledge in this area is disseminated, as well as its impact through the analysis of citations. This analysis can help future researchers in this field by providing an overview of the current literature that helps them identify new research approaches to position their own work and identify the most relevant authors in this field. Likewise, a comparison is made on coverage and overlap between the two main international databases WoS and Scopus. From the analysis of the 211 articles selected through an advanced search by terms with a time limit set in 2018, it is concluded that we are facing a very incipient field of knowledge that has aroused great interest since 2010, with about half of the articles published in the period 2012–2018. Although WoS and Scopus differ in general terms in scope and coverage policies, both systems are complementary and not exclusive. In the specific area of wastewater management, Scopus is the base that provides the best coverage taking into account the number of articles published and the number of citations received.
Hydrological Extremes in the Canadian Prairies in the Last Decade due to the ENSO Teleconnection—A Comparative Case Study Using WRF
Authors: Basu Soumik , Sauchyn David J. , Anis Muhammad Rehan
Published: October 2020

In the Prairie provinces of Alberta, Saskatchewan, and Manitoba, agricultural production depends on winter and spring precipitation. There is large interannual variability related to the teleconnection between the regional hydroclimate and El Niño and La Niña in the Tropical Pacific. A modeling experiment was conducted to simulate climatic and hydrological parameters in the Canadian Prairie region during strong El Niño and La Niña events of the last decade in 2015–2016 and 2010–2011, respectively. The National Center for Atmospheric Research (NCAR) Weather Research and Forecasting (WRF) model was employed to perform two sets of sensitivity experiments with a nested domain at 10 km resolution using the European Centre for Medium-Range Weather Forecasts Reanalysis (ERA) interim data as the lateral boundary forcing. Analysis of the hourly model output provides a detailed simulation of the drier winter, with less soil moisture in the following spring, during the 2015–2016 El Niño and a wet winter during the La Niña of 2010–2011. The high-resolution WRF simulation of these recent weather events agrees well with observations from weather stations and water gauges. Therefore, we were able to take advantage of the WRF model to simulate recent weather with high spatial and temporal resolution and thus study the changes in hydrometeorological parameters across the Prairie during the two extreme hydrological events of the last decade.
A Novel Approach to Harmonize Vulnerability Assessment in Carbonate and Detrital Aquifers at Basin Scale
Authors: Baena-Ruiz Leticia , Pulido-Velazquez David
Published: October 2020

The DRASTIC (D: Depth to water; R: Net recharge; A: Aquifer media; S: Soil media; T: Topography; I: Impact of vadose zone; C: Hydraulic conductivity) index is usually applied to assess intrinsic vulnerability in detrital and carbonate aquifers, although it does not take into account the particularities of karst systems as the COP (C: Concentration of flow; O: Overlying layers above water table; P: precipitation) method does. In this paper we aim to find a reasonable correspondence between the vulnerability maps obtained using these two methods. We adapt the DRASTIC index in order to obtain reliable assessments in carbonate aquifers while maintaining its original conceptual formulation. This approach is analogous to the hypothesis of “equivalent porous medium”, which applies to karstic aquifers the numerical solution developed for detrital aquifers. We applied our novel method to the Upper Guadiana Basin, which contains both carbonate and detrital aquifers. Validation analysis demonstrated a higher confidence in the vulnerability assessment provided by the COP method in the carbonate aquifers. The proposed method solves an optimization problem to minimize the differences between the assessments provided by the modified DRASTIC and COP methods. Decision trees and spatial statistics analyses were combined to identify the ranges and weights of DRASTIC parameters to produce an optimal solution that matches the COP vulnerability classification for carbonate aquifers in 75% of the area, while maintaining a reliable assessment of the detrital aquifers in the Basin.
Professional learning in the everyday provision of self-management support: situated knowledge and the problem with generic skills development
Authors: Doyle Sarah
Published: October 2020

Supporting people to self-manage long-term conditions, such as diabetes and heart disease, is a concern for health-care providers globally. Despite continued attention being paid to the production of educational resources for workforce development nationally and internationally, reports have highlighted that we do not yet know how to best help health-care professionals learn to undertake this work. This article employs sociomaterial workplace learning perspectives to show that many educational resources focus unhelpfully on generic skills and give insufficient consideration to the complicated and complex nature of this work. Using data from a wider study, which explored how health-care professionals in the United Kingdom learn to support children and their parents to self-manage type 1 diabetes, this article examines the informal learning that unfolds in the actions and conversations at work as professionals encounter, consider, explore and (temporarily) resolve specific challenges. This article provides novel insights into this area and suggests alternative ways of understanding, investigating and enabling professional knowledge.

Aerodynamic noise characteristics of the flow past a circular cylinder
Authors: Arun M.G. , Jothi T.J.S.
Published: October 2020

The present study experimentally investigates the aerodynamic noise from the flow past a fixed circular cylinder. The cylinders considered for the study have the diameters (d) in the range of 6 to 25 mm while its span length (L) is constant, which is 300 mm. The free stream velocity
is varied up to 50 m/s, and the corresponding Reynolds number (based on d) varies up to 8.3 104, thus maintaining the flow past the cylinder in the subcritical regime. The discrete narrowband frequency tones depicting the aeolian tones are noted in the spectra. The results showed that the
aeolian tone frequency decreases with an increase in the cylinder diameter and ceases to exist beyond the diameter of 15 mm. The corresponding Strouhal number of these tones is found to be in the range of 0.18 to 0.21, which is in congruence with the vortex shedding frequency in the subcritical
regime. The maximum overall sound pressure level for cylinders having tonal noise is higher by around 30 dB compared to the background noise. Directivity studies show that the noise level is higher along the perpendicular direction of the jet flow. A sixth power Mach number scaling of the
acoustic spectra shows a good collapse of the acoustic tonal amplitude.
Efficiency of an ANC system in the tractor cabin under controlled engine workload

Published: October 2020

The noise at the driver seat of an agricultural tractor is produced mostly by the engine. Its characteristic broadband noise spectrum varies considerably with engine workload. The passive noise control techniques adopted in tractor cabins, based on the application of sound-absorbing
and sound-proofing materials, are effective against medium-high frequencies noise components. The residual noise in sound-proof cabins is characterized by tonal emissions with low frequency components (< 500 Hz) but regarded as responsible for various disorders and diseases following long-term
exposure. In addition to the "A" weighting filter adopted to evaluate occupational exposure to noise, other approaches are reported in the scientific literature considered more appropriate to evaluate low frequency noise (LFN), as well as studies testifying the effectiveness of active noise
control (ANC) technologies in the low frequency range. In this article, the performance of an ANC system is evaluated in its ability to reduce noise levels inside the soundproof cabin of an agricultural tractor. To test this system, spectro-phonometric measurements of the equivalent linear
sound pressure level were conducted under controlled and repeatable engine workloads, obtained by connecting the tractor to a dynamometric brake, while simultaneously acquiring the related engine performance curves. Altogether, three different couples of loudspeakers were tested. Frequency
analysis in one-third octave band showed that the ANC system was mainly effective against LFN components (below 120 Hz) with peaks of reduction up to 20 dB. Then, on the basis of indications from previous studies, the data of linear sound pressure levels were processed applying the "A", "B",
and "C" weighting filters, to show the different emphasis given to the effects of the system. Eventually, a point-by-point composition of the equivalent levels of sound pressure was drawn over the whole range of the engine, to highlight the conditions in which the ANC system was more effective.
Implementation of a single-channel active noise control system with multiple reference sensors
Authors: Oh H.E. , Jeong W.B. , Hong C.
Published: October 2020

When multiple sources contribute competitively to the noise level, multi-channel control architecture is needed, leading to more cost and time for control computation. We, hence, are concerned with a single-channel control method with a single-reference signal obtained from a linear
combination of the multiple source signals. First, we selected 3 source signal sensors for the reference signals and the error sensor, selected a proper actuator and designed the controllers: 3 cases of single-channel feedforward controllers with a single-reference signal respectively from
the source signals, a multi-channel feedforward controller with the reference signals from the source signals, and the proposed controller with the reference signal from weighted sum of the source signals. The weighting factors and the filter coefficients of the controller were determined
by the FxLMS algorithm. An experiment was then performed to confirm the effectiveness of the proposed method comparing the control performance with other methods for a tower air conditioner. The overall sound pressure level (SPL) detected by the error sensor is compared to evaluate their performance.
The reduction in the overall SPL was obtained by 4.74 dB, 1.96 dB and 6.62 dB, respectively, when using each of the 3 reference signals. Also, the overall SPL was reduced by 7.12 dB when using the multi-reference controller and by 7.66 dB when using the proposed controller. Conclusively, under
the multiple source contribution, a single-channel feed forward controller with the reference signal from a weighted sum of the source signals works well with lower cost than multi-channel feedforward controller.

Published: October 2020

Indonesia is one of the nations putting resources into the modern area. Businesses influence the climate, outstandingly air quality. On the off chance that the air contamination ousted by modern fireplaces couldn't be handled appropriately, it would unfavorably influence human wellbeing. As of now, checking the air quality in certain zones just uses one apparatus. This is esteemed insufficient to depict the state of air quality in a given region. Then again, introducing more than one device would be extravagant. This exploration applied the idea of remote sensor organization (WSN) for air quality checking by introducing more than one sensor hubs in a specific area and one sink that demonstrations to gather information from the sensor hubs at that point sends them to the worker. Air quality information acquired by the sensor hubs were then ordered utilizing the grouping technique in information mining that is k-closest neighbor (K-NN). Preceding grouping utilizing K-NN, information standardization was performed, which creates a decimal scaling with great execution for air quality information. The k esteems utilized for the K-NN characterization are 5. The exactness of the framework is 94.28%, the accuracy is 85.16% and the review is 93.35%.

Published: October 2020

La imputación de los daños producidos por las sociedades mercantiles a través de sus órganos constitutivos ha tenido diversos enfoques, tanto en el ámbito doctrinario como jurisprudencial. El presente artículo pretende hacer algunas reflexiones y dejar sentado que si la persona jurídica indicada ocasiona daños por los actos de sus órganos constitutivos, no se refiere a un actuar por otro, y es dicha sociedad quien debe asumir la responsabilidad; por ende, no resultan de aplicación las normas referidas a la responsabilidad del  subordinado, sino más bien las normas que contienen el principio de no causar daño a nadie.

Entre obstáculos y posibilidades metodológicas: Género y Estado en un proyecto de investigación
Authors: Calandria Sol
Published: October 2020

¿Ordenaste los juguetes? ¿Acomodaste tu ropa? ¿Hiciste tu cama y la de tu hermano? Eran preguntas frecuentes que me hacía mi abuela cada vez que iba a almorzar antes de salir para la escuela. Recuerdo que muchas veces arribaba y, sin que ella llegara a preguntarme, le comentaba que esas tareas ya estaban realizadas. Sin embargo, un lunes me desperté y ya no tenía ganas de hacerle la cama a mi hermano porque pensaba que él, aun siendo más chico, ya podía hacérsela solo. Armé la mochila, me puse el guardapolvo y me fui a almorzar a lo de mi abuela… las tres preguntas no demoraron en llegar pero, esta vez, la respuesta fue diferente “No, hice la mía y no la de él, ¿por qué tengo que hacerla si él ya es grande y puede hacérsela solo?”, a lo que mi abuela respondió “Porque los varones no hacen esas cosas, las tareas de la casa las hacemos las madres y cuando ellas están muy ocupadas sus hijas”.En el año 2013 comencé a esbozar mi proyecto de investigación en una materia de la facultad donde la profesora nos hacía hurgar hacia dentro de nosotros mismos aquel tema que nos inquietara, nos desvelara y nos movilizara. Fue en este momento donde emergió mi interés por el tema de las maternidades y las paternidades, me interesaba indagar sobre cómo se habían construido socialmente y desarrollado a lo largo de la historia argentina. El tema que me generaba curiosidad y me atraía cuantiosamente estaba relacionado con aquellos mandatos que, sin tener ni un poco de acervo teórico, solía poner en cuestión a lo largo de mi infancia. Esto no era casual, me recuerdo y además siempre me dijeron, que era una niña muy curiosa, inquieta y sobretodo cuestionadora, siempre ponía en duda aquellas cosas que parecían naturales sobretodo los roles domésticos y las cosas que “debía hacer como mujer” porque solían no gustarme y divertirme poco. Mi trayectoria personal y las primeras pesquisas que realicé sobre el tema me generaron interés sobre aquellas mujeres que, a través de sus prácticas, pusieron en cuestión el binomio establecido socialmente entre la madre y sus hijos.En esta oportunidad, me propondré realizar un recorrido metodológico sobre la construcción del tema y problema de investigación, observando aquellas vetas y posibilidades conceptuales que hicieron posible su desarrollo. Especialmente haré hincapié en cómo las teorías del Estado, las teorías feministas del Estado y el género como categoría de análisis potenciaron las posibilidades de nuestra investigación. En este sentido, debo aclarar que este trabajo no resulta de la reconstrucción de un tema acabado de investigación sino que se encuentra en sus momentos iniciales y las reflexiones se realizarán sobre los diferentes momentos por donde transité a la hora de realizar el proyecto  y los avances iniciales.

Panen parsial adalah metode panen sebagian biomassa udang pada saat kegiatan operasional budidaya sedang berlangsung. Tujuan dari penelitian ini adalah menentukan konseptual model optimalisasi pengelolaan budidaya udang vannamei (L. vannamei) pola intensif berdasarkan prosentase estimasi panen parsial. Penelitian ini dilaksanakan dengan konsep desain kausal ex-post facto selama satu siklus budidaya intensif udang vannamei (L. vannamei). Hasil dari penelitian menunjukkan, selama masa budidaya parameter kualitas air yang meliputi pH, suhu, oksigen terlarut, nitrit, dan nitrat masih berada dalam ambang batas, sedangkan posfat, TAN, dan TOM berada diatas level ambang batas baku mutu untuk budidaya udang intensif. Untuk konsep model simulasi pengelolaan budidaya intensif dari skenario panen non-parsial, parsial 10%, dan parsial 20%. Sistem panen parsial 10% memiliki beberapa keunggulan dibandingkan dua sistem panen lainnya. Yakni, dengan diterapkannya simulasi panen parsial 10% didapatkan nilai efisiensi biomassa panen sebesar 88.08 kg dan efisiensi prosentase survival rate udang sebesar 11% dibandingkan dengan konsep panen parsial 20% atau non-parsial. Sehingga dapat disimpulkan, bahwa untuk konsep model pengelolaan budidaya udang vannamei (L. vannamei) pola intensif yang paling optimal berdasarkan hasil simulasi sistem pemodelan dinamis adalah konsep model budidaya panen parsial 10% dengan pelaksanaan panen parsial pada saat budidaya umur 60 hari.
Sacubitril/valsartan versus candesartan in women with heart failure receiving adjuvant therapy for breast cancer - is there any antiarrhythmic effect?

Purpose. To compare the effects of sacubitril/valsartan and candesartan on the occurrence and course of heart arrhythmias in the standard treatment of heart failure (HF) in patients with breast cancer receiving anthracycline antibiotics as part of adjuvant polychemotherapy.

Methods. The study involved 127 women aged 53 to 65 who received radical surgical and subsequent treatment for breast cancer in the MAMME clinic in Krasnodar in 2017-2020. Patients were prescribed adjuvant polychemotherapy, including anthracyclines, from 6 cycles. After randomization, standard HF therapy was carried out simultaneously with chemotherapy using sacubitril/valsartan (n=63) or candersartan (n=64). Initially, after the first, third and last courses of special cancer therapy, the heart rate was assessed using standard electrocardiography, 24-hour Holter monitoring of the electrocardiogram, transthoracic echocardiography, a 6-minute walk test were performed, and the level of the N-terminal pro-B type natriuretic peptide and high-sensitivity cardiac troponin I, the Minnesota Quality of Life Questionnaire for patients with chronic HF was completed.

Results. According to the 24-hour Holter monitoring of the electrocardiogram, the burden of ventricular premature contraction significantly decreased in the sacubitril/valsartan group (p=0.018), but not in candesartan group (p=0.326). The proportion of patients with persisting episodes of unstable ventricular tachycardia was also significantly reduced in patients randomized to take sacubitril/valsartan (p=0.027), but practically did not change in the candesartan group (p=0.785). Physical exercise tolerance, a 6-minute walk distance, and a quality of life indicator significantly improved only in the sacubitril/valsartan group. According to echocardiography, sacubitril/valsartan improved systolic function of the left ventricle, and candesartan only prevented its decline under the influence of the damaging effects of chemotherapy.

Conclusion. The efficacy and safety of treating patients who received cardiotoxic adjuvant chemotherapy for breast cancer, a decrease in the burden of ventricular arrhythmias, noted in the sacubitril/valsartan group, were a consequence of the intensification of treatment for HF. The cardiotoxic effect of anthracyclines can be overcome thanks to the pronounced positive neurohumoral effects of modern pharmacotherapy of HF using sacubitril/valsartan, which leads to a limitation of myocardial remodeling.

Buah pinang terdiri dari biji, serabut dan batok yang memiliki tingkat kekerasan tertentu. petani masih menggunakan pembelahan buah pinang secara manual dengan alat yang sederhana sebagai pembelah. Pembelahan buah pinang yang secara manual ini sangat lambat dan beresiko kecelakaan sangat besar. Dengan proses manual tersebut maka petani mengalami permasalahan yaitu harga yang lebih rendah jika hasil panennya dijual tanpa dibelah. Jika ingin menjual setelah dibelah maka kapasitas hasil buah pinang terbelah juga masih kecil. penelitian ini bertujuan membuat mesin pembelah pinang untuk meningkatkan kapasitas produksi buah pinang yang terbelah. Dari Analisa mesin pembelah pinag didapatkan hasil bahwa mesin ini mampu membelah buah pinang 120 kg/jam, dimana 75 % hasilnya terbelah dengan sempurna.
