Abstract. We present a novel approach to derive indirect global information on the hydroxyl radical (OH), one of the most important atmospheric oxidants, using state-of-art satellite trace gas observations (key sinks and sources of OH) and a steady-state approximation (SSA). This is a timely study as OH observations are predominantly from spatially sparse field and infrequent aircraft campaigns, so there is a requirement for further approaches to infer spatial and temporal information on OH and its interactions with important climate (e.g. methane, CH4) and air quality (e.g. nitrogen dioxide, NO2) trace gases. Due to the short lifetime of OH (~1.0 s), SSAs of varying complexities can be used to model its concentration and offer a tool to examine the OH budget in different regions of the atmosphere. Here, we use the well-evaluated TOMCAT three-dimensional chemistry transport model to identify atmospheric regions where different complexities of the SSAs are representative of OH. In the case of a simplified SSA (S-SSA), where we have observations of ozone (O3), carbon monoxide (CO), CH4 and water vapour (H2O) from the Infrared Atmospheric Sounding Interferometer (IASI) on-board ESA’s MetOp-A satellite, it is most representative of OH between 600 and 700 hPa (though suitable between 400–800 hPa) within ~20 % of TOMCAT modelled OH. The same S-SSA is applied to aircraft measurements from the Atmospheric Tomography Mission (ATom) and compares well with the observed OH concentrations within ~30 % yielding a correlation of 0.78. We apply the S-SSA to IASI data spanning 2008–2017 to explore the global long-term inter-annual variability of OH. Relative to the 10-year mean, we find that global annual mean OH anomalies ranged from −3.1 % to +4.4 %, with the largest spread in the tropics between −7.0 % and +7.7 %. Investigation of the individual terms in the S-SSA over this time period suggests that O3 and CO were the key drivers of variability in the production and loss of OH. For example, large enhancement in the OH sink during the positive 2015/2016 ENSO event was due to large scale CO emissions from drought induced wildfires in South East Asia). The methodology described here could be further developed as a constraint on the tropospheric OH distribution as further satellite data becomes available in the future.

Published: February 2022

Abstract. The China-Pakistan Economic Corridor (CPEC) is one of flagship projects of the One Belt One Road Initiative, which faces threats from mountain disasters in the high altitude region, such as glacial lake outburst floods (GLOFs). An up-to-date high-quality glacial lake dataset with critical parameters (e.g. lake types), which is fundamental to flood risk assessments and predicting glacier-lake evolutions, is still largely absent for the entire CPEC. This study describes a glacial lake dataset in 2020 for CPEC at 10–30 m resolution, which was produced from both Landsat and Sentinel optical images as well as glacial lake inventories in 1990 and 2000 from Landsat observation, using an advanced object-oriented mapping method associated with rigorous visual inspection workflows. The results show that Landsat derived 2234 glacial lakes in 2020, covering a total area of 86.31 ± 14.98 km2 with a minimum mapping unit of 5 pixels (4500 m2), whereas Sentinel derived 7560 glacial lakes in 2020 with a total area of 103.70 ± 8.45 km2 with a minimum mapping unit of 5 pixels (500 m2). The discrepancy implies that there is a significant quantity of small glacier lakes not recognized in existing glacial lake inventories and a more thorough inclusion of them require future efforts using higher resolution data. The total number and area of glacial lakes from consistent 30 m resolution Landsat images remain relatively stable despite a slight increase from 1990 to 2020. A range of critical attributes have been generated in the dataset, including lake types of two classification systems and mapping uncertainty estimated by an improved equation. This comprehensive glacial lake dataset has potentials to be widely applied in studies on glacial lake-related hazards and glacier-lake interactions, and is freely available at https://doi.org/10.12380/Glaci.msdc.000001 (Lesi et al., 2022).

Abstract. The assessment of rainfall erosivity is one of the main inputs in determining soil erosion. To calculate mean annual rainfall erosivity (R), long-term high-resolution observed rainfall time series are required, which are often not available. To overcome the issue of limited data availability in space, four methods are employed: the direct regionalisation of R, the regionalisation of 5 minute rainfall, the disaggregation of daily rainfall into 5 minute timesteps, and the use of a regionalised stochastic rainfall model. In addition the minimum time series length necessary to adequately estimate R is investigated. The impact of station density is considered for each of the methods. The study is carried out using 159 recording and 150 non-recording (daily) rainfall stations in the federal state of Lower Saxony, Germany. Results show that the direct regionalisation of mean annual erosivity leads to the best results in terms of relative bias and relative root mean square error (RMSE). This is followed by the regionalisation of the 5 minute rainfall data, which yields better results than the rainfall generation models, namely an alternating renewal model (ARM) and a multiplicative cascade model (Disagg). However, a key advantage of using regionalised rainfall models is the generation of rainfall time series that can be used for the estimation of the erosive event characteristics, which is not possible through the direct regionalisation of R. Using the stochastic ARM it can be shown that in most cases more than 60 years of data is needed in order to obtain a stable estimate of the annual rainfall erosivity. Estimation of soil erosion based on only 5 or 10 years of data can lead to uncertain values. Such short time series are often used when regionalisation is applied. Moreover, it was also found that resolution of measuring device has a significant effect on the rainfall erosivity and coarser data resolution can lead to high relative bias.
Continuous measurements of valley floor width in mountainous landscapes
Authors: Clubb Fiona Jane , Weir Eliot Francois , Mudd Simon Marius
Published: February 2022

Abstract. Mountainous landscapes often feature alluviated valleys that control both ecosystem diversity and the distribution of human populations. Alluviated, flat valley floors also play a key role in determining flood hazard in these landscapes. Various mechanisms have been proposed to control the spatial distribution and width of valley floors, including climatic, tectonic and lithologic drivers. Attributing one of these drivers to observed valley floor widths has been hindered by a lack of reproducible, automated valley extraction methods that allow continuous measurements of valley floor width at regional scales. Here we present a new method for measuring valley floor width in mountain landscapes from digital elevation models (DEMs). This method first identifies valley floors based on thresholds of slope and elevation compared to the modern channel, and uses these valley floors to extract valley centrelines. It then measures valley floor width orthogonal to the centreline at each pixel along the channel. The result is a continuous measurement of valley floor width at every pixel along the valley, allowing us to constrain how valley floor width changes downstream. We demonstrate the ability of our method to accurately extract valley floor widths by comparing with independent Quaternary fluvial deposit maps from sites in the UK and the USA. We find that our method extracts similar downstream patterns of valley floor width to the independent datasets in each site. The method works best in confined valley settings and will not work in unconfined valleys where the valley walls are not easily distinguished from the valley floor. We then test current models of lateral erosion by exploring the relationship between valley floor width and drainage area in the Appalachian Plateau, USA, selected because of its tectonic quiescence and relatively homogeneous lithology. We find that an exponent relating width and drainage area (cv = 0.3 ± 0.06) is remarkably similar across the region and across spatial scales, suggesting that valley floor width evolution is driven by a combination of both valley wall undercutting and wall erosion in the Appalachian Plateau. Finally, we suggest that, similar to common metrics used to explore vertical incision, our method provides the potential to act as a network-scale metric of lateral fluvial response to external forcing.

Abstract. Strategies of risk mitigation become effective when citizens facing hazardous phenomena adopt rational behaviors that contribute to lower the risk. This is more likely to occur when endangered communities share a widespread understanding of natural phenomena and their impacts. To reach this goal, educational and outreach materials are often organized around the descriptions of the natural process and its effects. Unfortunately, however, receiving correct information does not automatically grant the adoption of safe behaviors. Our teaching efforts may fail because of pre-existing biases, beliefs and misconceptions. The identification of these biases is important to plan effective educational campaigns, capable of providing the concepts that are needed to actually inform citizens’ choices about natural hazards. In this work, we present the results of an unconventional workshop on volcanic risk that we proposed to primary and secondary schools (ages 6–13), in Italy. The workshop is meant to explore the mental models that kids and youngsters have about volcanic eruptions and it takes the form of a creative exercise. We asked the students to draw and write a story in four frames, describing the onset and outcome of an imaginary eruption. All stories were then presented to the class, and always provided interesting hints to spark discussion about volcanic processes and hazards. As a whole, the collected stories provide an interesting, multifaceted description of volcanic eruptions and their potential impacts, as imagined by the kids. A careful analysis of this material provided interesting insights useful to improve future outreach material and educational plans. The workshop is simple to reproduce, even remotely, and could be easily extended to different types of hazards. While very simple to organize, this approach grants the secure engagement of most participants and offers a very different perspective on pupils’ understanding of natural phenomena.
A global assessment of nitrogen concentrations using spatiotemporal random forests
Authors: Sheikholeslami Razi , Hall Jim W.
Published: February 2022

Abstract. Anthropogenic nitrogen fluxes into surface freshwater bodies significantly impair water quality (WQ), pose serious health hazards, and create critical environmental threats. Quantification of the magnitude and impact of WQ issues requires identifying the key controls of nitrogen dynamics and assessing past and future patterns of global nitrogen flows. To achieve this, we adopted a data-driven, machine learning approach to build a space-time random forest model for simulating nitrogen concentration in 115 major river basins of the world. The proposed random forest-based WQ model regressed the monthly measured nitrogen concentration collected at 718 river stations across the globe for the period of 1992–2010 onto a set of 17 predictor variables with a spatial resolution of 0.5-degree. The resulting model was validated with data from river basins outside the training dataset, and was used to predict nitrogen concentrations in all river basins globally, including many with scarce or no observations. We predict that the regions with highest median nitrogen concentrations in their rivers (in 2010) were: United States, India, Pakistan, Bangladesh, China, and most of Europe. Furthermore, our results showed that the rate of increase between 1990s and 2000s was greatest in rivers located in eastern China, eastern and central parts of Canada, Baltic states, southern Finland, Pakistan, parts of Russia, mainland southeast Asia, and south-eastern Australia. We found that, globally, the most influential predictors of nitrogen concentrations are temporal: month of the year and cumulative month count, reflecting the secular trend. Apart from temporal variables, cattle density, nitrogen fertilizer application, temperature, precipitation, and pig population are the most influential predictors of nitrogen pollution of the river systems. The proposed global WQ model will provide a new tool to explore agricultural and land management strategies designed to reduce nitrogen pollution in freshwater bodies at large spatial scales.
Automated detection and classification of synoptic-scale fronts from atmospheric data grids

Published: February 2022

Abstract. Automatic determination of fronts from atmospheric data is an important task for weather prediction as well as for research of synoptic-scale phenomena. In this paper we introduce a deep neural network to detect and classify fronts from multi-level ERA5 reanalysis data. Model training and prediction is evaluated using two different regions covering Europe and North America with data from two weather services. We apply label deformation within our loss function, which removes the need for skeleton operations or other complicated post-processing steps as used in other work, to create the final output. We obtain good prediction scores with a critical success index higher than 66.9 % and an object detection rate of more than 77.3 %. Frontal climatologies of our network are highly correlated (greater than 77.2 %) to climatologies created from weather service data. Comparison with a well-established baseline method based on thermodynamic criteria shows a better performance of our network classification. Evaluated cross sections further show that the surface front data of the weather services as well as our network classification are physically plausible. Finally, we investigate the link between fronts and extreme precipitation events to showcase possible applications of the proposed method. This demonstrates the usefulness of our new method for scientific investigations.
Twenty-first-century Southern Hemisphere impacts of ozone recovery and climate change from the stratosphere to the ocean
Authors: Ivanciu Ioana , Matthes Katja , Biastoch Arne , Wahl Sebastian , Harlaß Jan
Published: February 2022

Abstract. Changes in stratospheric ozone concentrations and increasing concentrations of greenhouse gases (GHGs) alter the temperature structure of the atmosphere and drive changes in the atmospheric and oceanic circulation. We systematically investigate the impacts of ozone recovery and increasing GHGs on the atmospheric and oceanic circulation in the Southern Hemisphere during the twenty-first century using a unique coupled ocean–atmosphere climate model with interactive ozone chemistry and enhanced oceanic resolution. We use the high-emission scenario SSP5-8.5 for GHGs under which the springtime Antarctic total column ozone returns to 1980s levels by 2048 in our model, warming the lower stratosphere and strengthening the stratospheric westerly winds. We perform a spatial analysis and show for the first time that the austral spring stratospheric response to GHGs exhibits a marked planetary wavenumber 1 (PW1) pattern, which reinforces the response to ozone recovery over the Western Hemisphere and weakens it over the Eastern Hemisphere. These changes, which imply an eastward phase shift in the PW1, largely cancel out in the zonal mean. The Southern Hemisphere residual circulation strengthens during most of the year due to the increase in GHGs and weakens in spring due to ozone recovery. However, we find that in November the GHGs also drive a weakening of the residual circulation, reinforcing the effect of ozone recovery, which represents another novel result. At the surface, the westerly winds weaken and shift equatorward due to ozone recovery, driving a weak decrease in the transport of the Antarctic Circumpolar Current and in the Agulhas leakage and a cooling of the upper ocean, which is most pronounced in the latitudinal band 35–45∘ S. The increasing GHGs drive changes in the opposite direction that overwhelm the ozone effect. The total changes at the surface and in the oceanic circulation are nevertheless weaker in the presence of ozone recovery than those induced by GHGs alone, highlighting the importance of the Montreal Protocol in mitigating some of the impacts of climate change. We additionally compare the combined effect of interactively calculated ozone recovery and increasing GHGs with their combined effect in an ensemble in which we prescribe the CMIP6 ozone field. This second ensemble simulates a weaker ozone effect in all the examined fields, consistent with its weaker increase in ozone. The magnitude of the difference between the simulated changes at the surface and in the oceanic circulation in the two ensembles is as large as the ozone effect itself. This shows the large uncertainty that is associated with the choice of the ozone field and how the ozone is treated.

Purpose: Mental practice using motor imagery (MP) improves motor strength and
coordination in the upper and lower extremities in clinical patient populations. Its
effectiveness as a rehabilitation tool for patients with lingual weakness is not yet
well understood, nor are the underlying mechanisms within the context of swallow or
lingual MP. Using previously published data on a lingual and MP exercise program, the
objective of this study was to explore how MP of lingual exercise affects cortical
activation in healthy older adults over time and how neural changes correlate with
functional oral pressure outcomes. Method: A prospective randomized controlled study was
previously completed; older healthy participants were randomized to one of four
treatment groups receiving lingual MP, lingual physical practice, a combination of both,
and a sham control. This paper reports descriptive data on cortical activation during
both the physical and mental forms of lingual resistance in a subgroup of 13
participants using functional near-infrared spectroscopy at baseline and after 6 weeks
of the assigned exercise regimen. Results: Aggregated data indicates that participants
who completed 6 weeks of lingual exercise, either in physical or in MP form, had
decreased oxygenated hemoglobin when completing a maximal lingual pressure task.
Conclusions: Some participants in a lingual resistance MP program demonstrated trends
similar to those seen after strength training. Combining MP with physical training may
lead to greater changes in oxygenation compared to a physical or mental training program
alone, although given the small number of participants, it is important not to
overinterpret the results. MP is a promising, innovative approach that may enhance
traditional exercise-based swallowing rehabilitation.

Published: February 2022

Drawing on uncertainty management theory and social exchange theory, this research examined the interaction effect of organizational justice with perceived job insecurity in organizational citizenship behaviour. A hypothesised model was developed and tested using PLS-SEM (v 3.2.7) on a sample of 210 employees in the banking sector in Pakistan. The study found that at a high level of organizational justice, perceived job insecurity has a weak negative relationship with organizational citizenship behaviour, while at a low level of organizational justice; perceived job insecurity has a strong negative correlation with organizational citizenship behaviour. Results also support the interaction effect of perceived job insecurity and organizational justice on affective organizational commitment and psychological distress. This research highlights the significance of contextual variables which may help the practical community in managing their intellectual capital through casting an appropriate concern in organizational justice.

O novo coronavírus (SARS-CoV-2) é transmitido através de gotículas respiratórias e o uso de máscaras reutilizáveis em tecido que exercem uma função de barreira que bloqueia as grandes gotículas de projétil que chegam ao nariz ou à garganta. A ação proposta enfocou o uso de máscaras reutilizáveis em tecido como símbolo de respeito e solidariedade, sentimentos fundamentais para o enfrentamento da COVID-19. Utilizou-se meios digitais para disseminar informações científicas e estimular o uso de máscaras, além de propor modelos e protótipos de desenvolvimento de máscaras através de posts no Instagram e na TV da UFG. A ação recebeu engajamento de 2436 indivíduos. A universidade ao ocupar os meios de comunicação tem contribuído para diminuir o risco de atitudes impróprias por parte daqueles que recebem a informação. A pandemia de COVID-19 terá profundas repercussões na vida social. A universidade deve assumir a sua responsabilidade social de produzir conhecimento, traduzi-lo e promovê-lo entre comunidade.

Design thinking no ensino de ciências da natureza - quais são objetivos e aplicações nos trabalhos publicados entre 2010 e 2020?
Authors: Nascimento Rhaysa Myrelle Farias do , Leite Bruno Silva
Published: February 2022

A frequente utilização das metodologias ativas na sala de aula vem transformando o âmbito educacional e a relação professor/aluno com o processo de ensino e aprendizagem. A metodologia design thinking (DT) é uma delas e seu uso está começando a se tornar presente nas práticas docentes. No intuito de observar o DT no ensino, esta pesquisa teve como propósito analisar os objetivos e as aplicações dos trabalhos publicados sobre o design thinking no ensino das ciências da natureza. Para isso, realizamos uma revisão sistemática da literatura das publicações entre 2010 e 2020. A pesquisa foi baseada em duas perguntas norteadoras: “Quais os objetivos dos trabalhos publicados sobre o design thinking no ensino das ciências da natureza? E quais aplicações foram realizadas nesses trabalhos?”. Os resultados mostram que a utilização do design thinking, mesmo que crescente nas salas de aula, ainda é pouco utilizada na área das ciências da natureza. Além disso, identificamos sua aplicação de três formas distintas no âmbito educacional (como abordagem de inovação; como metodologia para resolução de problemas; como estratégia de ensino e aprendizagem). Embora existam dificuldades para a inserção dessa metodologia, os trabalhos apontam que para professores e estudantes, quando esta metodologia é aplicada, os resultados são considerados satisfatórios. Por fim, a utilização do design thinking como metodologia ativa no ensino das ciências da natureza pode contribuir para a construção do conhecimento de forma criativa e inovadora.
Educação digital - híbrida e onlife

Published: February 2022

A segunda década deste milênio tem desafiado diariamente as relações pessoais, econômicas, políticas, culturais, sociais e educacionais. As inovações estão a cada dia mais presentes na vida das pessoas por meio de diversos recursos, nos ambientes virtuais, nas redes sociais, com a ação dos algoritmos e das nanotecnologias. Esse universo tem ofertado um espaço fértil para estudos referentes às oportunidades de transformação dos ambientes relacionados ao ato de educar. Essa reflexão aprofunda-se em questões envolvendo a educação digital e híbrida e estrutura-se a partir da importância do conceito onlife e do paradigma da comunicação, apoiando o processo de ensino-aprendizagem. Discutem-se os elementos norteadores referentes à construção de uma educação que envolva mudanças nas estratégias didático-pedagógico-tecnológicas. A revisão bibliográfica traz um diálogo entre autores contemporâneos, como BATES (2016), CHRISTENSEN (2013), COSME (2009, 2017), FLORIDI (2015), HORN (2015), MOREIRA (2017, 2020), TRINDADE (2016, 2017), entre outros, que provocam estas pesquisadoras a estudar, entendendo que a necessidade de transformações mais efetivas na educação é capaz de oferecer relevância ao papel das tecnologias no processo de ensino-aprendizagem, tendo como premissa uma maior interação e uma comunicação efetiva como recurso para a construção de um conhecimento amplo e sustentável. Percebe-se também que, para a aplicação de propostas de educação híbrida, se torna fundamental um processo de aculturação de estudantes e educadores que possibilite a mudança de perfil desses agentes, desenvolvendo autonomia, autoestudo, planejamento, proatividade, comprometimento e protagonismo.

This study analyzed the progression of COVID-19 in the State of Espírito Santo, identifying the areas where the disease spread furthest. Temporal and spatial analysis were performed based on confirmed cases of the disease reported in the eSUS/VS System - State Health Department, from March 2020 to February 2021. The highest incidence was noted in July (ranging from 146.1 to 2,099.5 cases per 100,000 inhabitants in the municipalities of Espírito Santo State), with the majority being females, people aged 20 to 39 years and residents in cities in the metropolitan region. A positive and complete high association (p < 0.05) was identified in all months, with clusters containing a greater number of municipalities in April, May and June 2020 in the Central region of the state. The results of the present study indicated a continuous spread of COVID-19 since its introduction, especially in the cities in the Central region of the State of Espírito Santo. These findings present an important aid for decision making regarding the most effective strategies to control the disease. Furthermore, individual and collective protection measures against the transmission of the SARS-CoV-2 must be encouraged.

Published: February 2022

O objetivo deste artigo foi mapear como as poesias surdas abordam a temática de injustiça social e direitos humanos, pois é crescente a circulação das poesias sinalizadas em vários formatos e suportes, tais como saraus, slams, festivais e congressos ou, ainda, em espaços virtuais, como plataformas de vídeos e redes sociais. O recorte concentrou-se na coleta de dados de poesias disponíveis em ciberespaços: corpus de slams, videopoesia e saraus em Libras registrados em vídeo. Duas poesias são analisadas e cotejadas com autores de perspectivas pós-coloniais e articulações possíveis para o campo das Literaturas Surdas. Os resultados apontam que as injustiças sociais e o tensionamento dos direitos humanos são temáticas cruciais apresentadas nas poesias analisadas em Libras, que operam como denúncia da privação linguística das comunidades surdas, violência racial e de gênero, privação de acesso a direitos básicos em serviços públicos, dores causadas por padrões estéticos e luta pelos direitos LGBTQI+.

Emotions are considered as the real inner perception of a person. Emotions can never be ignored or completely eliminated from one’s life. The point of emotion like nostalgia has immense importance in our social life and the concept of nostalgia has a great shift from organizational environment to expanding marketing world. This research aimed to determine the purchase intention as outcome of nostalgic emotions of customers. This study finds the mediating effect of attachment and attitude in between nostalgic emotions and purchase intention. The data for this research was collected from the customers of Toyota and Honda motors located in two metropolitan cities of Pakistan (i.e Karachi and Lahore). The research has used non-probability sampling technique and cross-sectional research design was adopted. Furthermore, the adopted and modified questionnaire was used as survey instrument. The statistical outcomes were drawn from robust statistical technique, covariance-based structural equation modelling (CB-SEM). The results show that nostalgic emotion has positive and significant effect on purchase intention of customers. Moreover, mediating effect of attitude and attachment was confirmed in between nostalgic emotion and purchase intention. Consequently, this study confirmed that organizations should work on customer attitude and attachment which are the possible causes of nostalgic emotion, it may sufficiently increases customers’ purchase intention.
Symmetry trends of monoelement minerals
Authors: Vlahov Alexander
Published: February 2022

The number of the symmetry of each crystallographic class (NSCC) includes the sum of the orders of symmetry axes plus the number of symmetry planes plus one for a center of symmetry, if present. In 94.44% of cases, with increasing of NSCC values, the number of monoelement minerals crystallizing in the respective symmetry classes also increases. The density values Dc (gm/Å3) and Dcalc (g/cm3) of the monoelement minerals decrease with the increase of the atomic weight of chemical elements with consecutive or close atomic numbers in the periodic table. The NSCC values show a tendency to decrease with decreasing temperature and pressure of formation of monoelement minerals. At certain NSCC values, the highest the Dc (gm/Å3) and Dcalc (g/cm3) of monoelement minerals, the less probable becomes the possibility their polymorphic forms to be established. Polymorphic modifications denser than α-Fe (having Dc = 4.7049 gm/Å3 and Dcalc = 7.81 g/cm3) have not yet been established. The monoelement polymorphic modifications of As and S, crystallizing in the low symmetry crystal systems, are exceptions to Groth’s law. Most (91.67%) of the monoelement minerals crystallize in the holohedral classes. 2932 of all known 4106 mineral species (71.41%) also crystallize in the holohedral classes of different systems. The data presented suggest that the mineral species in general prefer holohedral classes, having also the highest NSCC values for the respective system. Therefore, the quantitative integral characteristic NSCC is informative in studies of all kinds of mineral assemblages grouped on the basis of different characteristics.

Penggunaan energi terbarukan harus menjadi perhatian utama masyarakat dan pemerintah Indonesia, tidak hanya sebagai upaya untuk mengurangi penggunaan energi fosil, tetapi juga untuk menciptakan energi bersih yang ramah lingkungan. Green diesel merupakan energi terbarukan untuk menggantikan solar. Salah satu bahan yang dapat diubah menjadi green diesel adalah minyak goreng. Green diesel diproduksi dengan menggunakan proses hydrotreating pada tekanan hidrogen 3 bar. 2000 ml minyak goreng direaksikan dengan gas hidrogen (H2) menggunakan katalis untuk mempercepat reaksi. Variabel non statis yang digunakan dalam penelitian ini adalah jenis dan jumlah katalis dan suhu. Setelah mendapatkan kondisi optimum untuk variasi jumlah katalis, penelitian dilanjutkan untuk mengetahui kondisi temperatur operasi terbaik dengan variasi temperatur 370 oC, 390 oC, 410 oC, 430 oC, 450 oC. Variasi katalis NiMo/ g-Al2O dengan 0%, 1%, 2%, 3%, dan 4%. Penggunaan katalis NiMo/?-Al2O3 sebesar 3% pada suhu 430 oC per 2000 ml sampel merupakan kondisi optimum dalam penelitian ini dan menghasilkan persentase rendemen sebesar 33,89%. Sifat fisik green diesel yang diperoleh dari penelitian ini meliputi densitas (764,41– 787,29kg/m3), viskositas kinematik (2,55–2,72mm2/s), kadar air (4003,48 -6094,38 ppm) , dan titik nyala (48,6 – 57,5 oC).

Published: February 2022

Introduction: The World Health Organization creates norms and guidelines for the adoption of good practices in health care that are provided to the surgical patient. In order to prevent and control infections associated with health care, the nurse must follow the guidelines for preparing the surgical patient for success. These infections can be particularly harmful to the elderly person given their vulnerability. The preoperative preparation, includes the trichotomy as one of the interventions to be performed, however, is one of the most controversial interventions that has caused in clinical practice, by the potential risk of infection in the surgical patient. Aim: To investigate the need for trichotomy, or removal of hair, in the preparation of the skin of the surgical patient, clarifying which is the most appropriate technique in the prevention of infection. Methodology: we conducted an umbrella review. The documentary research followed the consultation of bibliographic sources in the Cumulative Index to Nursing & Allied Health (CINAHL) and Public/Publisher Medline (PubMed) databases. The researched articles were grouped in a time horizon between 2011 and 2020. After data extraction, a narrative analysis was performed. Results: We found 40 articles from which 8 were selected. Conclusion: Trichotomy should be avoided by increasing the risk of infection of the surgical site. Innovative haircut and vacuum technologies can help in hair removal, mitigating the risk of contaminating the surgical incision. The timing of the trichotomy is not consensual among researchers.
