Influence of Animation- Versus Text-Based Delivery of a Web-Based Computer-Tailored Smoking Cessation Intervention on User Perceptions
Authors: Elling Jan Mathis , De Vries Hein
Published: July 2021

Computer-tailored (CT) digital health interventions have shown to be effective in obtaining behaviour change. Yet, user perceptions of these interventions are often unsatisfactory. Traditional CT interventions rely mostly on text-based feedback messages. A way of presenting feedback messages in a more engaging manner may be the use of narrated animations instead of text. The goal of this study was to assess the effect of manipulating the mode of delivery (animation vs. text) in a smoking cessation intervention on user perceptions among smokers and non-smokers. Smokers and non-smokers (N = 181) were randomized into either the animation or text condition. Participants in the animation condition assessed the intervention as more effective (ηp2 = .035), more trustworthy (ηp2 = .048), more enjoyable (ηp2 = .022), more aesthetic (ηp2 = .233), and more engaging (ηp2 = .043) compared to participants in the text condition. Participants that received animations compared to text messages also reported to actively trust the intervention more (ηp2 = .039) and graded the intervention better (ηp2 = .056). These findings suggest that animation-based interventions are superior to text-based interventions with respect to user perceptions.
Serum vitamin D3 levels in pregnant women with preeclampsia at third trimester of pregnancy
Authors: Sadek Anas , Baban Rayah , Al-Habib May , Khazaali Enas
Published: July 2021

Background: Preeclampsia (PE) is a pregnancy-specific condition, characterized by high blood pressure and proteinuria after 20 weeks of gestation. One of the hypotheses concerning the etiology of PE is vitamin D3 deficiency during pregnancy. Vitamin D3 is especially important during pregnancy as low maternal vitamin D3 stores may contribute to problems like low birth weight as well as an increased risk of maternal comorbidities.
Objectives: To evaluate serum vitamin D3 levels and how they can be affected by the severity of PE at the third trimester of pregnancy.
Methods: This case-control study included a total of 71 pregnant women at the third trimester of pregnancy (41 with PE and 30 without PE as controls). Vitamin D3 serum level was measured by enzyme-linked immune-sorbent assay (ELISA).
Results: The study’s findings showed no significant difference in serum vitamin D3 level (p>0.05) between controls (14.41±1.41ng/ml) and PE patients (14.32±1.00). As well, subgroup analysis revealed non-considerable changes between mild PE cases (15.92±1.73 ng/ml) and severe ones (13.07±1.09 ng/ml).
Conclusions: PE and its severity may have no significant effect on serum vitamin D3 levels of pregnant women at the third trimester of pregnancy.

Published: July 2021

Cardiac amyloidosis (CA) still represents a frequently missed cause of heart failure with preserved ejection fraction (HFpEF). In the light of many new and effective therapies for immunoglobulin light chain amyloidosis (AL) and for transthyretin amyloidosis (ATTR), screening for amyloidosis as an important and potentially treatable diagnosis under the HFpEF becomes mandatory. A step-by-step algorithm for CA in HF patients was already provided by the guidelines. This review summarizes the role of all imaging modalities and biomarkers in the diagnosis and prognosis of both subtypes, the algorithm for diagnosis of CA, and new therapeutic options. It is the first Romanian publication which intends to bring altogether the current recommendations in the diagnosis and management of CA.
Learning Curve for Left Bundle Branch Area Pacing – the Experience of a Romanian Academic Center
Authors: Pestrea Catalin , Gherghina Alexandra , Pintilie Irina , Ortan Florin
Published: July 2021

Introduction

There is an increasing interest in the past decade for more physiological pacing strategies due to detrimental long-term right ventricular pacing. His bundle pacing is the most physiological one, but it has some drawbacks, mainly an increased pacing threshold. Left bundle branch area pacing (LBBAP) emerged in the recent years as the next step in conduction system pacing. We present our initial experience and learning curve with this latter procedure.

Material and methods

During January 2019 and February 2021, 20 patients with pacing indications that failed initial permanent His bundle pacing underwent successful LBBAP.

Results

The mean age was 65.9 ± 12.7 years. The indications for cardiac pacing were AV block in 14 patients (70%) and cardiac resynchronization therapy in 6 patients (30%). At baseline, normal QRS complex was noted in 9 patients, a left bundle branch block pattern in 10 patients and a right bundle branch block in one patient. A total of 18 dual-chamber and one single chamber pacemakers were implanted and a cardiac resynchronization therapy defibrillator (CRT-D) device. The acute pacing threshold was 0.56±0.2 V at 0.4ms, the sensing threshold was 10.3±3.9 mV and the impedance was 684.9±112.2 Ω. The overall QRS duration decreased after LBBAP from 128.5 ± 27ms to 103.6 ± 17.4ms (p= 0.001). In patients with baseline wide QRS complex there was a highly significant decrease from 148.2 ± 11.6 ms to 104.7 ± 19.4 ms (p<0.001). The fluoroscopy time, including the time spent for His bundle location, was 13.8 ± 8.5 minutes. The pacing thresholds remained constant after three-months (0.6 ± 0.2 V vs. 0.56 ± 0.2 V at 0.4 ms). We had two intraprocedural septal perforations without any consequences and three micro dislodgements at follow-up with pure left septal capture.

Conclusion

Left bundle branch area pacing is a feasible physiological pacing technique with a high success rate and the potential to overcome the limits of permanent His bundle pacing. It can be successfully performed virtually in all types of pacing indications, including cardiac resynchronization therapy as provides a rapid and synchronous activation of the left ventricle.

Oscilações pluviométricas refletem na dinâmica atmosférica da área estudada, marcada pela intensa variabilidade observada na atuação da Zona de Convergência Intertropical como principal fator meteorológico causador de chuvas e as formações de vórtices ciclônicos de ar superior no período chu­voso. A análise da precipitação na área da bacia hidrográfica é de extrema importância para o geren­ciamento dos recursos hídricos, uma vez que se trata de áreas degradas e com realização de desmatamento para implantações agricultura de cerqueiro e a retirada da lenha. Muitas vezes, sem estruturação adequada à área se encaixa perfeitamente no contexto. Efetuou-se análise de frequência das distribuições dos totais anuais das chuvas mediante a elaboração dos gráficos. Utilizou-se a escala pro­posta por Meis et al. (1981) e pelos núcleos de meteorologia e CPTEC/INPE, disponibilizados por Xavier e Dornelas (2005), definida da seguinte forma: os valores anuais que mais se aproximaram do valor médio, foram caracterizados como intermediários, e os valores de precipitação anual que se afastaram da média foram considerados como representativos para os anos secos e úmidos. Utilizou-se escala de variação de 25% em relação à média para os meses intermediários; valores acima da es­cala caracterizaram-se como anos muito chuvosos, e os abaixo dos 25%, como anos secos em conformidade com Xavier e Dorne­las (2005). A aplicação do teste de significância estatística T de Student, destacou que os dados de precipitação de modo geral são 99% significativos.
A PAZ EM SANTO TOMÁS DE AQUINO: SUA NATUREZA E SUAS CAUSAS
Authors: Domingos Luiz Fabio , Oliveira Vitor , Manoel Luiz de Santana Claúdio
Published: July 2021

A paz e a unidade implicam não somente a concórdia entre diversas vontades, mas também a união dos apetites de um mesmo ente, isto é, para a paz não basta que a unidade seja entre indivíduos, mas deve ser, antes, interna a cada indivíduo. Este artigo buscou responder a seguinte questão: o que é a paz? existem meios para alcançá-la? Por meio de um estudo de revisão bibliográfica, este artigo buscou descrever o constructo filosófico “paz”, a sua natureza e as suas causas. Ademais, definiu-se como objetivo correlacionar tal conceito na perspectiva de Santo Tomás de Aquino, com as virtudes: justiça, sabedoria e caridade. Nesta direção, para que a paz se concretize em meio aos homens, é necessária a prática das virtudes que auxiliam na produção dessa paz tão desejada pela humanidade. Assim, concluiu-se que a paz não só é considerada, por Santo Tomás de Aquino, como um efeito de determinadas virtudes, mas pressupõe a ordem, a unidade e a quietude interior; além de tudo isso, trata-se de uma perfeita harmonia entre os apetites do homem.
A comparison of TOPSIS, grey relational analysis and COPRAS methods for machine selection problem in the food industry of Turkey
Authors: Özcan Sami , Çelik Ali Kemal
Published: July 2021

The paper aims to compare the results of the selection/choice of cream separators by using multi-criteria decision-making methods in an integrated manner for an enterprise with a dairy processing capacity of 80 to 100 tons per day operating in the Turkish food sector. A total of 7 alternative products and 7 criteria for milk processing were determined. Criterion weights were calculated using entropy method and then integrated into TOPSIS (Technique for Order Preference by Similarity to Ideal Solutions), GRA (Grey Relational Analysis) and COPRAS (Complex Proportional Assessment) methods. Sensitivity analyses were carried out on the results obtained from the three methods to check for their reliability. At the end of the study, similar alternative and appropriate results were found from the TOPSIS and COPRAS methods. However, different alternative but appropriate or suitable results were obtained from the GRA method. Sensitivity analysis of the three methods showed that all the methods used were valid. In the review of available and related literature, very few studies on machine selection in the dairy and food sector in general were found. For this reason, it is thought that the study will contribute to the decision-making process of companies in the dairy sector in their choice of machinery selections. As far as is known, this paper is the first attempt in extant literature to compare in an integrated manner the results of TOPSIS, COPRAS and GRA methods considered in the study.

Published: July 2021

Covid-19 not only exposed the vulnerability of most industries especially industries that relies on air travel and tourism but resulted in the exponential increase of unemployment in Malaysia. At the same time, online business or trade and ‘GIG’ economy increased exponentially. The sudden and unexpected loss of jobs had dire consequences for many people. This paper examines how policies enacted during the Covid-19 pandemic affected unemployment in Malaysia by focussing on the situation in Sabah, one of the three remaining partners in the formation of Malaysia. It draws on data from the Family, Women and Youth Survey conducted online towards the end of 2020, as well as secondary data. The study shows that hardship has been faced by many people, especially those previously in professional roles, and those who are younger. The widespread damage to the economy, and to social cohesion, will require significant collaboration between business and industry, the government and the people.

En el presente artículo se hace un análisis crítico -después de diez años- de los logros conseguidos con la implementación de los acuerdos de paz, de lo que se hizo a medias -o se hizo mal- y de lo que no se hizo. El análisis se centra en los tres componentes fundamentales de los acuerdos de paz: político, económico-social y jurídico-institucional, pues sólo a partir de una visión integral y de conjunto de ellos se podrá ponderar su significado real para la construcción de un nuevo orden social, económico y político. La tesis del artículo es que el espíritu de los acuerdos de paz era contribuir a la edificación de una sociedad justa y democrática, en la cual no tuvieran cabida situaciones de conflictividad político-militar como la vivida en El Salvador, durante los doce años de guerra civil.

Anticancer and antioxidant potential of Amaranthus cruentus protein and its hydrolysates
Authors:   ,   Durban University of Technology, Ramkisson Shanece
Published: July 2021

Traditionally, amaranth has been acknowledged to possess vital pharmacological properties with anticancer peptides having been found in Amaranthus cultivars. However, limited knowledge is available over the use of pepsin and alcalase enzymes to form hydrolysates. Thus, this study was aimed at comparing the in vitro anticancer effect of Amaranthus cruentus (grain) protein isolate and hydrolysates using alcalase, trypsin and pepsin. The safety of hydrolysates was investigated using the Ames mutagenicity and Brine Shrimp Lethality assay. Protein hydrolysates were thereafter investigated for their antioxidant potential using the FRAP, ABTS and DPPH assays. Subsequently, the protein hydrolysates were tested for their anticancer and apoptotic potential. The MTT assay was conducted to evaluate the cytotoxic potential of the protein hydrolysates using the HEK 293 (non-cancerous), A549 (cancerous) and MCF-7 (cancerous) cell lines. After that, morphological alterations were examined using the acridine orange and ethidium bromide double stain. Following this, the Annexin V apoptotic detection kit was used to quantify apoptosis together with the Glomax Caspase 3/7 kit to detect changes in the cell cycle Results show A. cruentus isolate and hydrolysates had no mutagenic response against Salmonella typhimurium TA 98 and TA 100 strains. The tested samples did not induce any significant increase in the death percentage of Artemia spp. in comparison to potassium dichromate (control). DPPH assay revealed that the hydrolysed samples had an enhanced scavenging activity compared to the unhydrolyzed sample, with pepsin having the greatest IC50 of 23.06 µg/ml. Amaranthus cruentus isolate (IC50 17.57 µg/ml) was a greater scavenger of the Fe+ ions compared to the control glutathione (IC50 79.81 µg/ml). For ABTS, all hydrolysates had a greater antioxidant scavenging potential compared to the isolate. The MTT cytotoxicity assay revealed that the isolate produced a greater cytotoxic effect on the MCF-7 and A549 cell line when compared to the control (camptothecin). For the non-cancerous cell line (HEK 293), trypsin hydrolysate had the highest toxicity. Apoptotic results revealed that trypsin hydrolysate was the most effective compared to the isolate, which was confirmed from morphological and Caspase 3/7 results. It may be concluded from the findings of this research that hydrolysates from food protein isolates have the potential for use as possible anticancer therapeutics. However, more research needs to be conducted to determine the peptides responsible for anticancer activity as well as the possible mechanism of action.

Published: July 2021

The article offers studies to determine the effectiveness of processing methods for the productivity of spring rapeseed and surepitsa on the dark gray forest soil of the Ryazan region. As a result, it was revealed that the maximum intensity of decomposition of flax tissue was recorded in the steam link of the crop rotation using the dump method of basic tillage for oilseed cabbage crops. The maximum yield of rapeseed was observed on the variant of the steam link of crop rotation + dump processing (31.3 c / ha), in the surepitsa (25.6 c/ha). A high increase in oilseeds in this variant is 4.7 c / ha, where the NSR05 factor with 0.97 c / ha relative to the minimum basic tillage was recorded in 2015. In the experiment, the trends of increasing the yield of oilseeds of spring rapeseed and surepitsa in the fallow link of the crop rotation relative to the row crop are revealed. The maximum oil content of rapeseed was noted in the rowed link of crop rotation during milling tillage (47.6%); in surepitsa – in the rowed link of crop rotation also during milling (45.1%).

Currently, there are 13,600 species of pteridophytes around the world, and is the second most dominant plant group. In India, there are 1200 pteridophyte species with 70 families and 192 genera. The pteridophyte hotspots in India are the Himalayas, Western Ghats, Eastern Ghats, Central India, and Andaman and the Nicobar Islands. The Western Ghats occupies only 6% of the Indian landmass and still holds a pteridophyte diversity of 383 species. Fern and fern allies are highly sensitive to changes in their natural habitat, thus habitat destruction, anthropogenic influences, climate change, etc., are causing a fast decline in their population. Epiphytic species are easily destroyed due to the felling of trees and because of this at present 41- 43% of epiphytic pteridophytes in India are reported to be threatened. It necessitates the frequent analysis of the pteridophyte flora of a region to ensure the existence of its species diversity. The potential of in-vitro and ex-situ conservation techniques can be explored for the conservation of threatened pteridophyte species

Beton Ltd.: A Case Study
Authors: Jordan Branko
Published: July 2021

The paper focuses on Beton Ltd., a theatre collective comprised of three actors, Primož Bezjak, Branko Jordan and Katarina Stegnar, established in 2010. Beton Ltd. emerged on the Slovenian performing arts scene with a collective approach to theatre-making and is thus a special case as far as non-hierarchical and collective production models in Slovenia are concerned. In the last ten years, Beton Ltd. has created seven performances: So Far Away: Introduction to Ego-logy (2010); I Say What I am Told to Say (2012); Everything We’ve Lost, While We’ve Gone on Living (2013); Revolting Man (2014); Ich kann nicht anders (2016); Große Erwartungen/Great Expectations (2018) and Mahlzeit (2019). Through introspective self-analysis, the paper elaborates on the necessary preconditions for the formation of a collective, as well as the conditions necessary for effective collaboration in performance making, combining a short historical overview of the case in question, including specific collaborative strategies developed by Beton Ltd. during the past decade.
Technical note: Uncertainties in eddy covariance CO2 fluxes in a semi-arid sagebrush ecosystem caused by gap-filling approaches

Abstract. Gap-filling eddy covariance CO2 fluxes is challenging at dryland sites due to small CO2 fluxes. Here, four machine learning (ML) algorithms including artificial neural network (ANN), k-nearest neighbours (KNN), random forest (RF), and support vector machine (SVM) are employed and evaluated for gap-filling CO2 fluxes over a semi-arid sagebrush ecosystem with different lengths of artificial gaps. The ANN and RF algorithms outperform the KNN and SVM in filling gaps ranging from hours to days, with the RF being more time efficient than the ANN. Performances of the ANN and RF are largely degraded for extremely long gaps of two months. In addition, our results suggest that there is no need to fill the daytime and nighttime NEE gaps separately when using the ANN and RF. With the ANN and RF, the gap-filling induced uncertainties in the annual NEE at this site are estimated to be within 16 g C m−2, whereas the uncertainties by the KNN and SVM can be as large as 27 g C m−2. To better fill extremely long gaps of a few months, we test a two-layer gap-filling framework based on the RF. With this framework, the model performance is improved significantly, especially for the nighttime data. Therefore, this approach provides an alternative in filling extremely long gaps to characterize annual carbon budgets and interannual variability in dryland ecosystems.

Abstract. Understanding aerosol–cloud–climate interactions in the Arctic is key to predicting the climate in this rapidly changing region. Whilst many studies have focused on submicrometer aerosol (diameter less than 1 µm), relatively little is known about the supermicrometer aerosol (diameter above 1 µm). Here, we present a cluster analysis of multiyear (2015–2019) aerodynamic volume size distributions, with diameter ranging from 0.5 to 20 µm, measured continuously at the Gruvebadet Observatory in the Svalbard archipelago. Together with aerosol chemical composition data from several online and offline measurements, we apportioned the occurrence of the coarse-mode aerosols during the study period (mainly from March to October) to anthropogenic (two sources, 27 %) and natural (three sources, 73 %) origins. Specifically, two clusters are related to Arctic haze with high levels of black carbon, sulfate and accumulation mode (0.1–1 µm) aerosol. The first cluster (9 %) is attributed to ammonium sulfate-rich Arctic haze particles, whereas the second one (18 %) is attributed to larger-mode aerosol mixed with sea salt. The three natural aerosol clusters were open-ocean sea spray aerosol (34 %), mineral dust (7 %) and an unidentified source of sea spray-related aerosol (32 %). The results suggest that sea-spray-related aerosol in polar regions may be more complex than previously thought due to short- and long-distance origins and mixtures with Arctic haze, biogenic and likely blowing snow aerosols. Studying supermicrometer natural aerosol in the Arctic is imperative for understanding the impacts of changing natural processes on Arctic aerosol.

Abstract. Reactive oxygen species (ROS) carried or induced by particulate matter (PM)
are suspected of inducing oxidative stress in vivo, leading to adverse health impacts such as respiratory or cardiovascular diseases. The oxidative potential (OP) of PM, displaying the ability of PM to oxidize the lung environment, is gaining strong interest in examining health risks associated with PM exposure. In this study, OP was measured by two different acellular assays (dithiothreitol, DTT, and ascorbic acid, AA) on PM10 filter samples from 15 yearly time series of filters collected at 14 different locations in France between 2013 and 2018, including urban, traffic and Alpine valley site typologies. A detailed chemical speciation was also performed on the same samples, allowing the source apportionment of PM using positive matrix factorization (PMF) for each series, for a total number of more than 1700 samples. This study then provides a large-scale synthesis of the source apportionment of OP using coupled PMF and multiple linear regression (MLR) models. The primary road traffic, biomass burning, dust, MSA-rich, and primary biogenic sources had distinct positive redox activity towards the OPDTT assay, whereas biomass burning and road traffic sources only display significant activity for the OPAA assay. The daily median source contribution to the total OPDTT highlighted the dominant influence of the primary road traffic source. Both the biomass burning and the road traffic sources contributed evenly to the observed OPAA. Therefore, it appears clear that residential wood burning and road traffic are the two main target sources to be prioritized in order to decrease significantly the OP in western Europe and, if the OP is a good proxy of human health impact, to lower the health risks from PM exposure.

Abstract. Well constrained volcanic emissions inventories in chemistry transport models are necessary to study the impacts induced by these sources on the tropospheric sulfur composition and on sulfur species concentrations and depositions at the surface. In this paper, the changes induced by the update of the volcanic sulfur emissions inventory are studied using the global chemistry transport model MOCAGE (MOdèle de Chimie Atmosphérique à Grande Échelle). Unlike the previous inventory (Andres and Kasgnoc, 1998), the updated one (Carn et al., 2016, 2017) uses more accurate information and includes contributions from both passive degassing and eruptive emissions. Eruptions are provided as daily total amounts of sulfur dioxide (SO2) emitted by volcanoes in the Carn et al. (2016, 2017) inventories, and degassing emissions are provided as annual averages with the related mean annual uncertainties of those emissions by volcano. Information on plume altitudes is also available and has been used in the model. We chose to analyze the year 2013, for which only a negligible amount of eruptive volcanic SO2 emissions is reported, allowing us to focus the study on the impact of passive degassing emissions on the tropospheric sulfur budget. An evaluation against the Ozone Monitoring Instrument (OMI) SO2 total column and MODIS (Moderate-Resolution Imaging Spectroradiometer) aerosol
optical depth (AOD) observations shows the improvements of the model results with the updated inventory. Because the global volcanic SO2 flux changes from 13 Tg yr−1 in Andres and Kasgnoc (1998) to 23.6 Tg yr−1 in Carn et al. (2016, 2017), significant differences appear in the global sulfur budget, mainly in the free troposphere and in the tropics. Even though volcanic SO2 emissions represent 15 % of the total annual sulfur emissions, the volcanic contribution to the tropospheric sulfate aerosol burden is 25 %, which is due to the higher altitude of emissions from volcanoes. Moreover, a sensitivity study on passive degassing emissions, using the annual uncertainties of emissions per volcano, also confirmed the nonlinear link between tropospheric sulfur species content with respect to volcanic SO2 emissions. This study highlights the need for accurate estimates of volcanic sources in chemistry transport models in order to properly simulate tropospheric sulfur species.
