Purpose: To assess maternal and fetal outcome of pregnant women with acute appendicitis underwent open versus laparoscopic appendectomy with emphasis on the pregnancy loss rate. Methods: This was a retrospective review of 116 pregnant women with acute appendicitis between 2011 and 2021 in single center, who were allocated either into open appendectomy (n=68) or laparoscopic appendectomy (n=48). Maternal and fetal outcome was recorded, tabulated and statistically analyzed. Results: There was no significant difference between both groups in terms of the rates of abortion [p>0.05, OR (CI 95%) 1.47 (0.42-5.18)], intrauterine fetal demise [p>0.05, OR (CI 95%) 0.94(0.2-4.39)], preterm delivery [p>0.05, OR (CI 95%) 1.9(0.56-6.45)], placental abruption [p>0.05, OR (CI 95%) 2.23(0.43- 11.53)], mode of delivery (p>0.05) and neonatal admission to NICU (p>0.05). There was no significant difference between both groups regarding perioperative data in terms of duration of symptoms before attending the hospital, final diagnosis, postoperative fever, re-operation, thromboembolism, surgical site infection and histopathology results (p>0.05). Laparoscopic appendectomy was associated with shorter operative time (p<0.05), shorter time for return of bowel motility (p<0.001) and shorter hospital stay (p<0.05). Conclusion: Laparoscopic appendectomy is safe, feasible and minimallyinvasive surgery during pregnancy and not associated with increased pregnancy loss when performed under strict criteria. Larger trials are warranted to confirm or refute these findings.

Published: February 2023

Background: While socioeconomic status (SES) indicators, such as family income, are among the primary drivers of individual health behaviors, the effects of these indicators on health behaviors may be weaker for racial/ethnic minorities, as described by the Marginalization related Diminished Returns (MDRs) phenomenon. Objectives: Built on the MDRs framework, this study used a national sample of 9 and 10 year old children with the following two aims: First, to test the association between household income and physical activity, and second, to test racial/ethnic variation in these associations. Methods: This cross-sectional study used the Adolescent Brain Cognitive Development (ABCD) baseline data. Participants included 9358 individuals who were either Black or White. Age, sex, racial/ethnicity, family structure (parental marital status), and frequency of physical activity were measured. Linear regression was used for data analysis. Results: Overall, high family income showed a positive association with physical activity in the overall population. We documented a statistically significant interaction between race/ethnicity and household income on frequency of physical activity, showing weaker effects of family income on children’s physical activity in Black than White families. Conclusion: We observed that household SES indicators, such as family income, have a larger effect on increasing children’s physical activity in White than Black families. Due to the existing MDRs, defined as weaker effects of family SES for racial/ethnic minority than White families, Black children from high SES families engage in less healthy behaviors than their White counterparts. MDRs sustain racial/ethnic disparities across class and SES lines.

The cost-effective production of green hydrogen is one of the most important challenges for a sustainable energy transition. To decrease the cost in the production of hydrogen through electrolysis, there are several obstacles that must be overcome. For instance, more active and stable anodes made of abundant and cheap materials will contribute to lowering the capital and operational expenditure of the process. It is well-known that the oxidation of water requires high overpotentials, which is the main limitation for the performance of the device. In this context, substituting the oxidation of water (OER) at the anode of electrolyzers by the oxidation of biomass-derived substances contribute to the overall process by decreasing the power input of the devices and, in some cases, by producing value-added chemicals. Herein, we re-visited some of the most important fundamental aspects of the (electro-)oxidation of alcohols and polyols on metal-based catalysts, focusing on reaction descriptors. Then, we moved to the (electro-)oxidation of these molecules on metal oxides, re-visiting some of the literature about their application in heterogeneous catalysis and for OER, to get insights about the relation of the structure of the materials and their activity. Due to the lack of fundamental knowledge about the electro-oxidation of alcohols and polyols on metallic oxides and to the vast literature about the use of perovskite oxides for OER, we propose to start systematic studies using perovskite oxides for the electrooxidation of alcohols and polyols. Consequently, we presented results for LaCoO3, LaFeO3, LaMnO3, and LaNiO3, and propose a mechanism for the electro-oxidation of glycerol based on the formation and reactivity of MOH(O) species. We believe that fundamental and systematic studies in this topic would permit the establishment of reaction descriptors, speeding up the searching for suitable materials for this reaction and paving the way for a most cost-effective production of green hydrogen.
Diastereo- and Enantioselective (3+2) Cycloaddition of a New Palladium-Aza-Oxyallyl Intermediate
Authors: Scuiller Anaïs , Casaretto Nicolas , Archambeau Alexis
Published: February 2023

Cycloaddition of azaoxyallyl cations or other C-(C=O)-N synthon precursors is a well-established route towards lactams and other N-heterocycles but, despite the wide synthetic scope of this approach, enantioselective versions remain scarce. We herein report 5-vinyloxazolidine-2,4-diones (VOxD) as a suitable precursor of chiral palladium-aza-oxyallyl intermediates. In the presence of electrophilic alkenes, (3+2) -lactam cycloadducts could be formed with high level of diastero- and enantioselectivity.
Limitations of atomistic modeling to reveal ejection of proteins from charged nanodroplets
Authors: Kwan Victor , Ballaney Pranav , Titiksha Titiksha , Consta Styliani
Published: February 2023

Molecular dynamics using atomistic modeling is frequently used to extract the mechanisms of macroion release from electrosprayed droplets. However, atomistic modeling is currently feasible for only the smallest window of droplet sizes that omits the droplet history. The relevance of the observations made in this narrow window to the actual droplet evolution has not been addressed. Here, we perform a systematic study of desolvation mechanisms of poly(ethylene glycol) (PEG), protonated peptides of different compositions and protonated proteins in order to examine whether atomistic modeling can establish the extrusion mechanism of proteins from droplets. Atomistic modeling of PEG charging shows that above a critical droplet size charging occurs transiently by transfer of ions from the solvent to the macroion, while below the critical charge, the capture of the ion from PEG has a lifetime sufficient for extrusion of the charged PEG from an aqueous droplet. This is the first report of the role of the droplet curvature in the charging of macroions. Modeling of the process in droplets of various sizes allow us to extrapolate the charging mechanisms in systems that cannot be modeled atomistically yet. Simulations even with highly hydrophobic peptides show that partial extrusion of a peptide from the droplet surface is rare relative to desolvation by drying-out of the protonated peptide. Differently from what has been presented in the literature we argue that atomistic simulations have not sufficiently established extrusion mechanism of proteins from droplets and their charging mechanism. Moreover, we argue that release of highly charged proteins can occur in earlier stage of a droplet's lifetime than that that is atomistically modeled. In this earlier stage, we emphasize the key role of jets emanating from a droplet at the point of charge-induced instability in the release of proteins.

Published: February 2023

Operando wide-field optical microscopy imaging yields a wealth of information about the reactivity of metal interfaces, yet the data are often unstructured and challenging to process. In this study, we harness the power of unsupervised machine learning (ML) algorithms to analyze chemical reactivity images obtained dynamically by reflectivity microscopy in combination with ex situ scanning electron microscopy to identify and cluster the chemical reactivity of particles in Al alloy. The ML analysis uncovers three distinct clusters of reactivity from unlabeled datasets. A detailed examination of representative reactivity patterns confirms the chemical communication of generated OH- fluxes within particles, as supported by statistical analysis of size distribution and finite element modelling (FEM). The ML procedures also reveal statistically significant patterns of reactivity under dynamic conditions, such as pH acidification. The results align well with a numerical model of chemical communication, underscoring the synergy between data-driven ML and physics-driven FEM approaches.
ARTICLE CITATION CONTRIBUTION INDICATOR: APPLICATION IN ENERGY AND ENVIRONMENT
Authors: Liu Zhenling
Published: February 2023

Journal Impact Factor (JIF) is a widely used and accepted indicator for measuring journal influence in academia, but it has certain limitations. Article Citation Contribution Indicator (ACCI) is defined and introduced in bibliometrics analysis. The ACCI, a new basic indicator, was adopted to analyze the papers published between 2019 and 2020 in Energy & Environment, papers with ACCI>0 and with ACCI<0 were classified into two groups. This paper employed the keyword co-occurrence technology to discover the commonalities of citation positive and citation negative papers. Citation positive papers made relatively a larger contribution to the JIF and might contain important scientific information, subsequent papers may learn from the research directions of these papers, while the citation negative papers failed to improve the performance of the journal in terms of JIF. The research showed that ACCI is an academic tool that can be used to guide scientific directions; the work flow can be used for other journal analysis. The academic journal editorial board can use it to identify potential high influence authors

Published: February 2023

During monsoon season Islamabad and Rawalpindi receive unpredicted intense precipitation, which causes flooding in the areas of Rawalpindi along with Nullah Lai. This study included the qualitative content analysis of urban flooding and analyzed the extreme water events of Nullah Lai for the period 2010 to 2020. The main purpose to conduct this research was to determine the causes and effects of an increase in urban flooding. For this purpose 26 scientific pieces of writing (19 scientific published journal articles, 4 websites, and 3 reports) relevant to the specific concept of the research problem and research question were reviewed and analyzed. The study found the natural climate change, glaciers melting, rainfall, and temperature fluctuations) and anthropogenic (human actions, LULC change, infrastructure, industrial waste etc) factors as the main causes of the increase in urban flooding. Thus, this study suggests installing modern technology to predict intense natural weather patterns (precipitation) and must adopt sustainable and resilient infrastructure to control and mitigate future adverse impacts of urban floods in rapidly urbanized areas.

Published: February 2023

Climate-induced water related problems are major challenge for mountain communities and little is known on changes and impacts to local people. This paper focuses on climate change issues and its water related consequences to people of Sikles village. Climatic data were collected and analyzed for trend and variability analysis. Water availability was analyzed based on discharge measurement through a volumetric approach and demand was estimated from total population and per capita daily water requirement as prescribed by WHO. Local perception was assessed from household questionnaire survey (n=60). The result showed that average annual maximum and minimum temperature is increasing at the rate of 0.049℃ and 0.006℃ annually. Similarly, annual precipitation is also slightly increasing but in unpredictable pattern whereas number of rainy days is decreasing at 1.123 days per year. Both hot and cold climate extremes and intense rainfall are seen frequently in recent years. Landslide is major water related problem in the area and has more risk due to intense rainfall. Locals perceived that water availability in the sources is decreasing, also current demand and supply analysis in dry period showed there is scarcity of water if collection time concentered only on morning and evening. Water source protection and plantation is most adopted practices to protect water and minimize landslide hazards. Local water use regulation for efficient use of water, development of water storage and distribution system and promotion of green interventions could be important future strategy to face the predicted water related problems in the village.

From Fiqh Matn to Code of State: Shifting Representation of the Multaqā from the Seventeenth to the Nineteenth Centuries Ottoman World and Beyond
Authors: KOPUZ Kasım
Published: February 2023

Ibrāhīm al-Ḥalabī’s (d. 956/1549) Multaqā al-abḥur, published in 1517, quickly became one of the most authoritative fiqh texts in the Ottoman Empire. Ottoman authors treated it just as fiqh text. In their early writings, Western scholars also represented the book to their audiences as a fiqh book. However, by the late seventeenth century onward, Western authors started to portray the book as a code of the state in the modern sense of a uniform law. Some Muslim scholars in the late nineteenth century fallowed the same path. Thus, the representation of the Multaqā shifted from being a fiqh text to a code of the state. This article traces the historical process of this shift and argues that viewing the Multaqā as a code of the state was a misrepresentation that emerged under the influence of the notion of a modern nation-state.

Published: February 2023

Nipa sap is a sweet and translucent beverage that originated from nipa palm (Nypa
fruticans) tree. In Sarawak, nipa sap become raw material for nipa sugar or locally known
as gula apong. However, nipa sap undergoes natural fermentation that alters the properties
of nipa sap including taste, aroma and quality. Fermented nipa sap is whitish colour with
an unpleasant aroma and taste, which makes it unacceptable for consumption. Hence, it is
no longer suitable to make nipa sugar. This study aimed to determine the physicochemical
and microbiological changes of nipa palm sap from fresh to fermented. The nipa sap was
allowed to undergo natural fermentation at room temperature for 56 days. Samples were
collected every 24 hrs for the first week and once a week in the subsequent week. The
selected physiochemical qualities were analysed using high-performance liquid
chromatography (HPLC) whereas the microbial content was analysed using spread
plating. Fresh nipa sap showed the highest load of sugar (334.2±12 g/L) with sucrose as
the main sugar found (231.5±4.3 g/L), followed by fructose (42.1±1.2 g/L), and glucose
(29.7±3.2 g/L). Fresh nipa sap also possessed the lowest load of ethanol (0.08±0.03 g/L),
lactic acid (1.09±0.06 g/L), and acetic acid (0.05±0.01 g/L) as well as microbial and yeast
concentration. Later, ethanol started to accumulate on day 4 (9.80±0.1 g/L) and the
highest peak was on day 21 (19.1±2.01 g/L). The microbial concentration changed as
well, affecting the quality of nipa sap. As nipa sap plays such an important role in the
lifestyle of people in Sarawak, this study provides a better understanding of the
microbiology and biochemistry of its fermentation process. Hence, proper planning for
handling fresh nipa sap should be considered to ensure the quality of value-added product
production.

Published: February 2023

This study used semi-structured interviews to explore the career development process and influencing factors among eight Roma students. Following the analysis, eight areas emerged: 1) criteria for choosing a career option, 2) role models, 3) proactive personality, 4) support, 5) barriers, 6) work values, 7) critical consciousness, and 8) relevance of career guidance. The results show that the family is an essential source of moral support, role models, and persuasion in choosing certain educational and career options. Participants made decisions based on interests in certain areas and had work values predominantly related to prestige and appropriate financial rewards for their needs. All participants received support through positive measures and demonstrated a proactive personality in capitalizing on the support they received and overcoming the barriers they encountered, the most common being financial constraints. All students have a clear picture of how their ethnicity is perceived in society and the labor market and some of them are actively involved in improving the socio-economic context of young Roma.

Authors: Dani Robi Rahmat , Kartika Juang Gema , Sari Maryati
Published: February 2023

Pinto peanut (Arachis pintoi Krap & Greg.) is a legume that is usually used as a cover crop, bio mulch in fruit and vegetable plantations, ornamental plants, and animal feed. Pinto peanut has many benefits; through the symbiosis with rhizobacteria they can fix nitrogen, as ground cover can reduce the risk of landslides, inhibit weed growths, and is a source of nectar for bees. Arahcnis pintoi can be propagated vegetatively or generatively, but generative propagation is hard to conduct in the tropics because it takes a long time for the plants to produce seeds. Our study was conducted to determine the effect of GA3 application on seed production of A. pintoi. The experiment was arranged in a single factor randomized complete block design with GA3 concentration of 0, 75, 150, 225, and 300 ppm. An orthogonal polynomial test was conducted to determine the effective concentrations for GA3 on seed formation and seed viability. Harvested seeds were stored for 1 month, then sown on sand medium; the seeds were soaked in 1% KNO3 solution to break seed dormancy prior. Our study showed that the GA3 effective concentration range from 130.69 ppm to 137.16 ppm, indicated by the increase the number of flowers at 105, 120, 135, and 150 DAT up to 28.59% compared to control. GA3 at 126.80 ppm can also increase the number of harvested pods by 18.16%. The effect of GA3 on vegetative growth was shown by the increase in the growth of new individual plants concentration, i.e. 53.25 new individual plant with GA3 application of 141.88 ppm.

The Covid-19 pandemic affected many sectors, one of which was the economic sector, so the government released three fiscal stimulus policy packages to deal with the impact of the Covid-19 pandemic on the economy. Starting on February 25, 2020, for the first volume, then for the second volume on March 21, 2020, and then the third volume of the fiscal stimulus package was released on March 31, 2020. The purpose of this paper is to identify the impact of the fiscal stimulus on economic output and labor income in Indonesia. The research method uses an input-output analysis model in identifying the impact of fiscal stimulus on economic output and labor income. The results of the analysis of the impact of the fiscal stimulus volume 1 show that the increase in fiscal stimulus in 2020 on the output of the Accommodation and Food and Drink Provision sector; Real Estate; and Other Services sectors cause changes in economic output. There are 3 sectors with the largest economic output affected by the increase in fiscal stimulus, namely the Agriculture, Forestry, and Fisheries sectors; Processing industry; and Wholesale and Retail Trade; Car and Motorcycle Repair. The impact of the fiscal stimulus volume 2 in the form of tax incentives, especially on PPh 21 in the Manufacturing Industry, has proven to have an impact on changes in total income in all sectors. The results of the analysis of the impact of fiscal stimulus volume 3 show that the increase in fiscal stimulus in 2020 on the output of the Agriculture, Forestry, and Fisheries sector; Processing industry; and Health Services and Social Activities cause changes in economic output. There are 3 sectors with the largest economic output affected by the increase in fiscal stimulus, namely the Agriculture, Forestry, and Fisheries sectors; Processing industry; and Health and Social Activities.

Objective This study aimed to observe the changes in people’s depressive levels over 9 months since the coronavirus disease of 2019 (COVID-19) outbreak as well as to identify the predictors of people’s depressive levels including COVID-19 infection fear in the context of South Korea in 2020.Methods For these purposes, four cross-sectional surveys were periodically implemented from March to December 2020. We randomly recruited 6,142 Korean adults (aged 19 to 70) by using a quota survey. Along with descriptive analysis, which included a one-way analysis of variance and correlations, multiple regression models were built to identify the predictors of people’s depressive levels during the pandemic. Results Overall, people’s depressive levels and fear of COVID-19 infection gradually increased since the COVID-19 outbreak. In addition to demographic variables (i.e., being a female, young age, unemployed, and living alone) and the duration of the pandemic, people’s COVID-19 infection fear was associated with their depressive levels.Conclusion To ameliorate these rising mental health issues, access to mental health services should be secured and expanded, particularly for individuals who present greater vulnerabilities due to socioeconomic characteristics that may affect their mental health.

Objective This study aimed to explore the characteristics and factors related to changes in cognitive function in vulnerable individuals with cognitive impairment during the coronavirus disease 2019 (COVID-19) pandemic.Methods Among patients who visited a local university hospital with subjective cognitive complaints, those who had been tested for cognitive function at least once after the onset of COVID-19 and tested regularly at least three times within the last 5 years were included (1st, the initial screening; 2nd, the test immediately before the COVID-19 pandemic; 3rd, the most recent test after the pandemic). Finally, 108 patients were included in this study. They were divided into groups according to whether the Clinical Dementia Rating (CDR) was maintained/improved and deteriorated. We investigated the characteristics of the changes in cognitive function and related factors during COVID-19.Results When comparing CDR changes before and after COVID-19, there was no significant difference between the two groups (p=0.317). Alternatively, the main effect of the time when the test was conducted was significant (p<0.001). There was also a significant difference in the interaction between the groups and time. When the effect of the interaction was analyzed, the CDR score of the maintained/ improved group significantly decreased before COVID-19 (1st–2nd) (p=0.045). After COVID-19 (2nd–3rd), the CDR score of the deteriorated group was significantly higher than that of the maintained/improved group (p<0.001). Mini-Mental State Examination recall memory and changes in activity during COVID-19 were significantly associated with CDR deterioration.Conclusion Memory dysfunction and decreased activity during the COVID-19 pandemic are strongly related to the deterioration of cognitive impairment.

Objective Optimism, social support, and spirituality can be important factors related to coronavirus disease-2019 (COVID-19) stress. However, studies investigating the influence and interplay of optimism, social support, and spirituality on COVID-19 simultaneously are still few. This study is aimed to explore the influence of optimism, social support, and spirituality on COVID-19 stress in the Christian church community.Methods A total 350 participants were included in this study. This study was cross-sectionally conducted by using an online survey on optimism, social support, spirituality, and COVID-19 stress that were measured by the Life Orientation Test-Revised (LOT-R), Multidimensional Scale of Perceived Social Support Scale (MSPSS), Spiritual Well-Being Scale (SWBS), and COVID-19 Stress Scale for Korean People (CSSK). The prediction models for COVID-19 stress were analyzed by using univariate and multiple linear regression.Results Based on the results of univariate linear regression, subjective feelings on income (p<0.001) and health status (p<0.001), LOTR (p<0.001), MSPSS (p=0.025), and SWBS (p<0.001) scores were significantly associated with COVID-19 stress. The multiple linear regression model with subjective feelings on income and health status and SWSB score was significant (p<0.001) and explained 17.7% of the variance (R2=0.177).Conclusion This study showed that subjective feeling on low income, those who had poor health status, lower optimism, lower perceived social support, and lower spirituality were significantly affected with COVID-19 stress. Especially, the model with subjective feelings on income and health status, and spirituality showed highly significant effects, despite the interaction with associated factors. To cope with unpredictable stressful situations like the COVID-19 pandemic, integrated interventions on psycho-socio-spiritual aspect are warranted.

Published: February 2023

Objective Thought-action fusion (TAF), which is a tendency to make the relationship between one’s thoughts and external consequences, is a dysfunctional belief linked to obsessive-compulsive disorder (OCD). While the TAF is commonly evaluated using the Thought-Action Fusion Scale (TAFS), it cannot fully reflect the actual experience of experimentally evoked TAF. In the present study, we applied a multiple-trial version of the classic TAF experiment and evaluate two variables, reaction time (RT) and emotional intensity (EI).Methods Ninety-three patients with OCD and 45 healthy controls (HCs) were recruited. The participants were asked to read the name of a close or neutral person embedded in different positive (PS) or negative (NS) TAF statements. During the experiments, RT and EI were gathered.Results The OCD patients presented with longer RT and lower EI in the NS condition than HCs. In each group, the HCs showed a significant relationship between RT in the NS condition and TAFS scores, whereas the patients did not, although they had higher TAFS scores than the HCs. In contrast, the patients showed a trend toward a correlation between RT in the NS condition and guilt.Conclusion These findings may indicate our multiple-trial version of the classical TAF showed reliable results of the two new variables, especially RT, in the task and allow to newly identify paradoxical patterns in which the TAFS scores are high but actual performance is impaired, that is, the inefficient activation of TAF in OCD.
Examining the relationship between TPACK and STEAM through a bibliometric study
Authors: Karampelas Konstantinos
Published: February 2023

This research is a bibliometric study that focuses on publications containing both terms “technological pedagogical content knowledge” (TPACK or TPCK) and “science, technology, engineering, arts, and mathematics” (STEAM). The former addresses knowledge that teachers are expected to gain, whereas the latter addresses a new integrating subject field. Both terms dominate contemporary education research, especially in relation to technology and its impact on education. These two terms have been researched individually by bibliometricians. The aim of this research is to examine articles that combine these terms, as there seems to be a lack of such studies. With the help of the Scopus platform, 2,608 articles published since 2007 were collected and analyzed.
Pre-service mathematics teachers' views of nature of science in the context of COVID-19
Authors: Sengul Ozden
Published: February 2023

A framework for K-12 science education (National Research Council [NRC], 2012) supports science learning on social and political issues to make informed decisions and solve problems. Socio-scientific issues have been considered as a context to teach characteristics of nature of science (NOS). This study is a qualitative study in nature to examine how pre-service mathematics teachers define science and address different aspects of science and scientific literacy in the context of coronavirus (COVID-19). Data sources included written reports and reflections on basic science-related questions. Responses from 50 pre-service mathematics teachers were analyzed through thematic analysis. The results indicated that pre-service mathematics teachers defined science as a product in the form of systematic knowledge, fact or theories-laws-models, and they provided informed or partially informed views on empirical, sociocultural, tentativeness, and subjectivity aspects by referring to cognitive, developmental, and sociocultural dimensions of science literacy. Pre-service mathematics teachers’ definition of science as accumulated knowledge was not aligned with their desirable views on aspects of NOS. The study suggests possible implications for further studies.

Published: February 2023

O objetivo deste trabalho foi modelar o crescimento do girassol sob diferentes épocas de semeadura, condições de disponibilidade hídrica e solos. O experimento foi conduzido em Santa Maria/RS (Argissolo) e Panambi/RS (Latossolo), sob três condições hídricas (déficit, excesso e controle) e semeadura no início de setembro e janeiro. Para determinar a condição hídrica do solo realizou-se o balanço hídrico sequencial diário. As plantas foram coletadas em quatro estádios de desenvolvimento fenológico: V10, R2, R6 e R8. Para analisar o crescimento do girassol utilizaram-se: a taxa de crescimento da cultura, taxa de crescimento relativo, taxa de assimilação líquida, taxa de crescimento foliar relativo, duração da área foliar, razão da área foliar e área foliar específica. Além disso, uma modelagem do crescimento em matéria seca de cada parte da planta e da profundidade do sistema radicular. Nossos dados mostraram que o déficit hídrico foi a condição que mais afetou o crescimento do girassol, seguido pelo excesso hídrico. O modelo de crescimento pico gaussiano, de maneira geral, foi o que melhor se adequou a matéria seca e a profundidade de raízes do girassol, apresentando bom ajuste aos dados medidos e podendo ser utilizados para diferentes locais com boa precisão para as condições nas quais foi desenvolvido este trabalho.

Published: February 2023

O zoneamento agrícola é uma ferramenta que utiliza variáveis climáticas, edáficas e socioeconômicas de cada cultura, para identificar áreas de menor risco ao estabelecimento e cultivo de espécies vegetais de uma determinada região. Os primeiros zoneamentos agrícolas no Brasil foram publicados na década de 1950. A partir dos anos 90, intensificam-se as pesquisas em metodologias específicas para dar suporte ao Programa de Zoneamento Agrícola de Risco Climático do MAPA. O objetivo deste trabalho foi avaliar o estado atual da pesquisa científica na área do zoneamento agrícola no Brasil. A metodologia empregada foi a análise bibliométrica implementada no R. A análise foi conduzida usando duas bases de dados indexadas Web of Science e Scopus e bases não indexadas. A matriz de dados foi submetida a análise descritiva. Foram analisados um total de 84 artigos oriundos de 26 fontes bibliográficas, 266 autores com 0,27 artigos por autor e índice de colaboração de 3,76. No período analisado, observou-se um crescimento no número de publicações. Constatou-se uma concentração de trabalhos publicados com autores principais provenientes dos Estados do Sul e Sudeste. Observou-se forte colaboração científica entre os grupos de pesquisa brasileiros. As fontes de dados mais citadas foram INMET, ANA, IAPAR, EPAGRI, FEPAGRO.

O Instituto Agronômico do Paraná (IAPAR) foi fundado em 1972 com a missão de gerar pesquisas e tecnologias para a agropecuária paranaense. Após a geada devastadora de julho de 1975, o Governo do Paraná incentivou uma série de políticas de diversificação de áreas de cultivo de café. No entanto, a expansão de culturas anuais por todo o Estado resultou no aumento dos níveis de erosão e degradação dos solos. Desde o início das atividades do IAPAR, a equipe de agrometeorologia desenvolveu e adaptou uma série de tecnologias para apoiar o desenvolvimento da agricultura paranaense. As pesquisas focaram em estudos para minimizar danos de geadas, análises da climatologia do Estado, técnicas de manejo em sistemas de produção sustentáveis, zoneamento agrícola, mudanças climáticas e sistemas de monitoramento e alerta. Este trabalho faz uma síntese das principais contribuições dos estudos agrometeorológicos realizados.

Published: February 2023

A diversidade em microclimas existentes em Santa Catarina favorece o cultivo de diversas espécies, entre elas, frutíferas de clima temperado. O interesse pelo cultivo da oliveira não é recente no Brasil, no entanto a atividade ainda carece de informações técnicas com experimentação local para orientação à escolha de locais de menor risco climático à produção. O objetivo deste trabalho foi analisar riscos climáticos à cultura da oliveira em Santa Catarina com base em informações bibliográficas para as cultivares de baixa exigência em frio ‘Arbequina’, ‘Arbosana’ e ‘Koroneiki’. Com base nos dados meteorológicos, foram calculadas as horas de frio (≤ 12,5 °C), Graus-dia (Tb=10 °C) e a probabilidade de ocorrência de temperaturas mínimas (0, -1 e -2). Os resultados apontam a geada como um fator bastante restritivo ao cultivo, principalmente no ano de implantação da cultura. Existe probabilidade de não atendimento de horas de frio em função da variabilidade espacial e interanual. O total de precipitação anual contribui para que o Estado de Santa Catarina não seja considerado como área preferencial ao cultivo. Este estudo foca na utilização conjunta das cultivares ‘Arbequina’, ‘Arbosana’ e ‘Koroneiki’, de baixa exigência de frio em Santa Catarina.
