Persistence on Task, Executive Functions, and the Perceived Meaning of Occupations Among Children
Authors: Rosenberg Limor
Published: June 2022

Importance: Persistence on task—the voluntary continuation of a goal-directed action despite difficulties—is described as a behavioral component of involvement in an occupation; however, it has not yet been extensively studied in the context of pediatric occupational therapy.

Objective: To describe persistent children, compared with their less persistent peers, in terms of age, sex, executive functions (EF), and perceived meaning of occupations and to assess whether intrapersonal factors, EF, and the perceived meaning of occupations can predict persistence.

Design: Cross-sectional.

Setting: A community in Israel.

Participants: Typically developing healthy children (N = 180) ages 6.0 to 12.5 yr and their parents.

Outcomes and Measures: The Tower of Hanoi task (TOH; seven discs) was used to assess persistence on task. EF were assessed with the TOH (three discs) and the Verbal Working Memory test. Occupational meaning—challenge, value, sense of time, and autonomy—was assessed with the Perceived Meaning of Occupation Questionnaire.

Results: Twenty-six children (14%) completed the task. They were older than their peers, performed better on most of the EF tests, and perceived more autonomy in their everyday activities (Mann–Whitney U = 1,185.0, p < .001). However, only the perceived autonomy of occupations was found to be a statistically significant factor that predicted persistence on task (B = –0.12, SE = 0.05, Wald = 7.60, p = .01).

Conclusions and Relevance: Perceived autonomy in everyday activities is crucial for persistence on task. Occupational therapy practitioners can promote children’s involvement and persistence in cognitive tasks by supporting a sense of autonomy in everyday activities, although further study is needed.

What This Article Adds: This article highlights the contribution of perceived autonomy in everyday activities to children’s involvement and persistence on task by providing empirical data on children’s persistence on task with regard to their EF and perceived meaning of occupations. Children who persisted longer and completed tasks differed from their less persistent peers in terms of age and EF. However, perceived autonomy in everyday activities was the only predictor of task completion.

Published: June 2022

The Iglesia basin, in the San Juan Province, is the northern part of a Cenozoic piggy-back basin (the Iglesia-Calingasta-Uspallata basin), located above of the active flat-slab subduction zone of western Argentina. This basin is located between two mountain ranges, the Cordillera Frontal to the west and the Precordillera to the east, affected by thin and thick skinned tectonics, respectively. It is elongated in a north-south direction (70 km) and has a maximum width of 35 km. We have analyzed 17 seismic reflection lines corresponding to more than 500 km of interpreted sections. A strong reflection at 0.5-2 s is interpreted as indicative of shales and sandstones in the upper part of the Agua Negra Formation (Carboniferous); this represents a seismic basement for the Iglesia basin clearly separating stratified (shallower) from chaotic (deeper) reflectors. Several high angle faults have been recognized in the interpreted seismic lines affecting the Neogene fill and even the basement; some of them correlate with structures observed at the surface such us El Tigre Fault System. A 3D model shows the seismic top of basement smoothly deepening down to 3,650 m beneath the Pismanta area. The basement continues upward to the east with a steeper slope clearly defining an asymmetrical shape for the basin. Moreover, there are three depocenters of similar maximum depths around the geothermal hot spring of the Pismanta center. Some of the interpreted faults may be helping in the outflow process of meteoric water heated by a normal geothermal gradient. Considering earthquake data framework, our observations correlate with transpressive deformation likely associated with El Tigre Fault System, which affects Neogene and Pleistocene strata of the Iglesia Group.

The Relationship Between Blood Lactate Levels and Clinical Outcomes in Patients Taking Drugs for Suicide: A Retrospective and Descriptive Study
Authors: GÜLLÜPINAR Birdal , SAĞLAM Caner , ÜNLÜER Erden Erol
Published: June 2022

Introduction: Acute poisoning that causes significant morbidity and mortality worldwide is a preventable public health problem. In the evaluation of critically ill patients in emergencies, lactate is a useful biomarker. This study aims to investigate whether the mortality, morbidity, and intensive care hospitalization of patients presenting to the emergency department with drug intake for suicide can be determined by the blood lactate levels measured on admission.

Material-Method: Patients over the age of 18 who presented to the emergency department between 1 January 2019 and 1 January 2020 due to acute poisoning were included in this single-center retrospective study. The relationship between the blood lactate levels measured on admission and the clinical outcome of the patient was examined. The student t-test was used to compare groups with normally distributed data, while the chi-square test was used for non-normally distributed or ordinal data. p˂0.05 was considered statistically significant.

Findings: The data of 223 patients were analyzed. The median age was 28, and the female ratio was 68.6%. The most commonly ingested drugs were analgesics with 35%, other drugs with 33.6%, antidepressants with 24.7%, and other psychotropics with 22.4%. 192 of the patients were discharged following the treatment, 31 patients were admitted to the service or intensive care unit, and 3 patients died within the first 24 hours after the intensive care unit admission. When the factors related to hospitalization were examined, male gender, high mean age, high lactate level, and analgesic and other psychotropic drug intake were found to be related to hospitalization. On the other hand, old age (48.00, ±16.70), high lactate levels (6.77, ±6.52), and low bicarbonate levels (17.40, ±3.05) were associated with mortality.

Conclusion: Blood lactate measured on admission is an important biomarker to predict both mortality and morbidity in patients presenting to the emergency department due to the use of drugs for suicidal purposes.
Varieties of Electoral Dominance
Authors: Ziegfeld Adam
Published: June 2022

Dominant political parties rule for prolonged periods of time by winning successive multiparty elections. However, the term "dominant party" encompasses an extremely diverse set of parties, ranging from ones winning unremarkable vote shares in established democracies to those garnering massive popular majorities in free but unfair elections. To grapple with such heterogeneity, this article proposes a three-part typology based on the foundations of a party's electoral dominance—whether extremely high votes shares, steadfast support from legislative allies, or a favorable translation of votes into seats or office. These three types are internally homogenous but distinct from one another in ways predicted by the typology. The puzzles posed by each dominant-party type and the kinds of answers required to address those puzzles differ markedly.

Published: June 2022

Abstract. Diurnal variations of cloud cover and cloud vertical distribution are of great importance to earth-atmosphere system radiative budgets and climate change. However, thus far, these topics have received insufficient attention, especially on the Tibetan Plateau (TP). This study focuses on the diurnal variations of total cloud cover, cloud vertical distribution, and cirrus clouds and their relationship to meteorological factors over the TP based on active and passive satellite observations, reanalysis data, and CMIP6 outputs. Our results are consistent with previous studies but provide new insights. The results show that total cloud cover peaks in the afternoon, especially over the southeastern TP, but the spatial and temporal distributions of clouds from different datasets are inconsistent. To some extent, it could be attributed to subvisible clouds missed by passive satellites and models. Compared with satellite observations, the amplitudes of the diurnal variations of total cloud cover obtained by the reanalysis and CMIP6 models are obviously smaller. The CATS can capture varying pattern of the vertical distribution of clouds and corresponding height of peak cloud cover at middle and high atmosphere levels, although it underestimates the cloud cover of low-level clouds especially over the southern TP. Compared with CATS, ERA5 cannot capture the complete diurnal variations of vertical distribution of clouds and the MERRA-2 has a poorer performance. We further find that cirrus clouds, which are widespread over the TP, show significant diurnal cycle and spatial and temporal distribution characteristics, with peak cloud cover over 0.4 during 15:00–21:00 LT over the northeastern TP. Be different from tropic, where thin cirrus (0.03<optical depth<0.3) dominate, opaque cirrus clouds (0.3<optical depth<3) are the dominant cirrus clouds over the TP. The cloud cover of opaque cirrus reaches a daily maximum of ~0.24 over the northeastern TP at 15:00 LT, and are influenced by diurnal variations of the 2-m temperature and 250 hPa vertical velocity. Although subvisible clouds (optical depth<0.03), which have a potential impact on the radiation budget, are the fewest among cirrus clouds over the TP, the cloud cover can reach 0.1 during 21:00–03:00 LT, and their diurnal cycle is obviously consistent with that of the high-level relative humidity. Our results will help reduce uncertainties in simulations of diurnal variations of cloud cover in models and reanalysis data over the TP region.
Impact of eastern and central Pacific El Niño on lower tropospheric ozone in China
Authors: Jiang Zhongjing , Li Jing
Published: June 2022

Abstract. Tropospheric ozone, as a critical atmospheric component, plays an important
role in influencing radiation equilibrium and ecological health. It is
affected not only by anthropogenic activities but also by natural climate
variabilities. Here we examine the tropospheric ozone changes in China
associated with the eastern Pacific (EP) and central Pacific (CP) El
Niño using satellite observations from 2007 to 2017 and GEOS-Chem
simulations from 1980 to 2017. GEOS-Chem reasonably reproduced the
satellite-retrieved lower tropospheric ozone (LTO) changes despite a slight
underestimation. In general, both types of El Niño exert negative
impacts on LTO concentration in China, except for southeastern China during
the pre-CP El Niño autumn and post-EP El Niño summer. Ozone budget
analysis further reveals that for both events, LTO changes are dominated by
the transport processes controlled by circulation patterns and the chemical
processes influenced by local meteorological anomalies associated with El
Niño, especially the changes in solar radiation and relative humidity.
The differences between EP- and CP-induced LTO changes mostly lie in southern
China. The different strengths, positions, and duration of the western North
Pacific anomalous anticyclone induced by tropical warming are likely
responsible for the different EP and CP LTO changes. During the post-EP El
Niño summer, the Indian Ocean capacitor effect also plays an important
role in mediating LTO changes over southern China.
Evaluating seasonal and regional distribution of snowfall in regional climate model simulations in the Arctic

Published: June 2022

Abstract. In this study, we investigate how the regional climate model HIRHAM5 reproduces the spatial and temporal distribution of Arctic snowfall when compared to CloudSat satellite observations during the examined period of 2007–2010. For this purpose, both approaches, i.e., the assessments of the surface snowfall rate (observation-to-model) and the radar reflectivity factor profiles (model-to-observation), are carried out considering spatial and temporal sampling differences. The HIRHAM5 model, which is constrained in its synoptic representation by nudging to ERA-Interim, represents the snowfall in the Arctic region well in comparison to CloudSat products. The spatial distribution of the snowfall patterns is similar in both identifying the southeastern coast of Greenland and the North Atlantic corridor as regions gaining more than twice as much snowfall as the Arctic average, defined here for latitudes between 66 and 81∘ N.
Excellent agreement (difference less than 1 %) in the Arctic-averaged annual snowfall rate between HIRHAM5 and CloudSat is found, whereas ERA-Interim reanalysis shows an underestimation of 45 % and significant deficits in the representation of the snowfall rate distribution. From the spatial analysis, it can be seen that the largest differences in the mean annual snowfall rates are an overestimation near the coastlines of Greenland and other regions with large orographic variations as well as an underestimation in the northern North Atlantic Ocean. To a large extent, the differences can be explained by clutter contamination, blind zone or higher resolution of CloudSat measurements, but clearly HIRHAM5 overestimates the orographic-driven precipitation. The underestimation of HIRHAM5 within the North Atlantic corridor south of Svalbard is likely connected to a poor description of the marine cold air outbreaks which could be identified by separating snowfall into different circulation weather type regimes. By simulating the radar reflectivity factor profiles from HIRHAM5 utilizing the Passive and Active Microwave TRAnsfer (PAMTRA) forward-modeling operator, the contribution of individual hydrometeor types can be assessed. Looking at a latitude band at 72–73∘ N, snow can be identified as the hydrometeor type dominating radar reflectivity factor values across all seasons. The largest differences between the observed and simulated reflectivity factor values are related to the contribution of cloud ice particles, which is underestimated in the model, most likely due to the small sizes of the particles. The model-to-observation approach offers a promising diagnostic when improving cloud schemes, as illustrated by comparison of different schemes available for HIRHAM5.

Published: June 2022

Abstract. Airborne observations of vertical aerosol particle distributions are crucial for detailed process studies and model improvements. Tethered balloon systems represent a less expensive alternative to aircraft to capture shallow atmospheric boundary layers (ABL). This study presents the newly developed cubic aerosol measurement platform (CAMP) for balloon-borne observations of aerosol particle microphysical properties. With an edge length of 30 cm and a weight of 9 kg, the cube is an environmentally robust instrument platform intended for measurements at low temperatures, with a particular focus on applications in cloudy Arctic ABLs. The aerosol instrumentation onboard CAMP comprises two condensation particle counters with different lower detection limits, one optical particle size spectrometer, and a miniaturized absorption photometer. Comprehensive calibrations and characterizations of the instruments were performed in laboratory experiments. The first field study with a tethered balloon system took place at the TROPOS research station in Melpitz, Germany, in the winter of 2019. At ambient temperatures between -10 and 15 °C, the platform was operated up to 1.5 km height on 14 flights under a clear sky and cloudy conditions. The continuous aerosol observations at the ground station served as a reference for evaluating the CAMP measurements. During two subsequent balloon flights on the late morning of 15 February, descending layers with increased concentrations of nucleation mode particles were observed above a shallow well-mixed surface layer separated by a weakening temperature inversion. A subsequent increase in nucleation mode particles on the ground after the balloon flights suggests a downward mixing of the particles. Based on the laboratory instrument characterizations and the observations during the field campaign, CAMP demonstrated the capability to provide comprehensive aerosol particle measurements in cold and cloudy ABL.
Spruce bark beetle (Ips typographus) infestation cause up to 700 times higher bark BVOC emission rates from Norway spruce (Picea abies)

Published: June 2022

Abstract. Emissions of biogenic volatile organic compound (BVOC) from the bark of Norway spruce (Picea abies) trees can be affected by stress, such as infestation of spruce bark beetles (Ips typographus). We studied the difference in emission rates from healthy spruce bark and infested spruce bark, the influence of time since spruce bark beetle infestation started and the difference in emission rates from bark beetle drilled entry holes and exit holes. Bark chamber measurements on both healthy trees and infested trees were performed during the summer of 2019 at two sites in Sweden. To consider the seasonal pattern of the spruce bark beetle, we divided the emission rates from infested trees into two seasons, an early season dominated by entry holes and a late season with mainly exit holes. Our findings show a significant difference in emission rates from healthy and infested trees, independent of season. The seasonal average standardized emission rate from healthy trees was 31.89 ± 51.67 μg m-2 h-1 (mean ± standard deviation), while the average standardized emission rates from infested trees were 6385 μg m-2 h-1 and 2102 μg m-2 h-1 during early and late season respectively. We also found an exponentially decreasing relationship with BVOC emission rates and time since infestation started where the emission rates reached the same level as the constitutive BVOC emission rates from bark after around one year. When comparing bark monoterpene BVOC emission rates with emission rates from needles, we found that the constitutive needle emission rates were 11 times higher than the constitutive bark emissions. However, the emission rates from infested Norway spruce tree bark were instead 6 to 20 times higher than the constitutive needle emissions, causing substantial increases in the total tree BVOC emission rate (550 % to 1900 % increase). This study adds evidence that spruce bark beetle induced bark BVOC emissions are higher than previously thought and highlights the need for further research with more samples more frequently throughout the season to fully understand the impact, which is required to quantify spruce bark beetle infestations impacts on the atmospheric chemistry and climate change.

Abstract. There is an increasing demand for the creation and restoration of tidal marshes around the world, as they provide highly valued ecosystem services. Yet restored tidal marshes are strongly vulnerable to factors such as sea level rise and declining sediment supply. How fast the restored ecosystem
develops, how resilient it is to sea level rise, and how this can be steered by restoration design are key questions that are typically challenging to assess due to the complex biogeomorphic feedback processes involved. In this paper, we apply a biogeomorphic model to a specific tidal-marsh restoration project planned by dike breaching. Our modeling approach integrates tidal hydrodynamics, sediment transport, and vegetation dynamics, accounting for relevant fine-scale flow–vegetation interactions (less than 1 m2) and their impact on vegetation and landform development at the landscape scale (several km2) and in the long term (several decades). Our model performance is positively evaluated against observations of vegetation and geomorphic development in adjacent tidal marshes. Model scenarios demonstrate that the restored tidal marsh can keep pace with realistic rates of sea level rise and that its resilience is more sensitive to the availability of suspended sediments than to the rate of sea level rise. We further demonstrate that restoration design options can steer marsh resilience, as they affect the rates and spatial patterns of biogeomorphic development. By varying the width of two dike breaches, which serve as tidal inlets to the restored marsh, we show that a larger difference in the width of the two inlets leads to higher biogeomorphic diversity in restored habitats. This study showcases that biogeomorphic modeling can support management choices in restoration design to optimize tidal-marsh development towards sustainable restoration goals.
Sensitivity analysis of input ground motion on surface motion parameters in high seismic regions: a case of Bhutan Himalaya
Authors: Tempa Karma , Aryal Komal Raj , Chettri Nimesh , Forte Giovanni , Gautam Dipendra
Published: June 2022

Abstract. Historical earthquakes demonstrate that strong motion characteristics and local soil condition, when coupled, significantly influence seismic site response. Interestingly, most of the Himalayan earthquakes depicted anomalous behavior per the site conditions historically. Being one of the most active seismic regions on earth, the eastern fringe of the Himalaya has observed many devastating earthquakes together with non-uniform damage scenarios. To quantify such anomalies, we evaluate surface motion parameters for a soft soil deposit located in the city of Phuentsholing in western Bhutan. Using one-dimensional site response analysis, the sensitivity of ground motion variation is estimated. This study accounts for the earthquakes of moment magnitudes 6.6 to 7.5 with a wide variation in peak ground acceleration (PGA). To dissect the characteristics of six inputted ground motions on eight local ground conditions, a sensitivity analysis is performed statistically. The statistical correlation of the response datasets and the linear regression model of the bedrock outcrop and the surface motion spectral acceleration along the stratified depth are examined to quantify the variation in surface motion parameters. The results highlight that the strong motions with PGA greater than 0.34 g demonstrate greater sensitivity, leading to some anomalies in response parameters, especially amplification. Similar results were obtained for the low PGA range (<0.1 g).

The XRD experiment was performed to determine the substitutional effects on structural parameters. FTIR spectroscopy and I-V measurements were carried out to analyze the spectral and electrical behavior of substituted samples. X-ray diffraction patterns revealed the FCC structure of the prepared samples The value of average crystallite size was noticed between 25.89-39.51 nm, while lattice constant was found in the range 8.37-8.41 Å. Both the low and the high frequency absorption bands were confirmed by FTIR technique. Tetrahedral band was noted in the range 463-495 cm-1 while octahedral band was observed in range 558-560 cm-1. The dc resistivity was observed to decrease with increase in temperature which indicates the semi-conductor like behavior of the prepared samples. Dielectric study showed that both the dielectric constant and the tangent loss factor were decreased with rise in the applied field frequency.

The ductile behavior is achieved through Poisson’s and Pugh's ratios. The indirect band gaps of 1.9 eV, 1.7 eV and direct band gap of 1.3 eV for ZnIn2S4, CdIn2S4 and HgIn2S4 spinel sulfides, respectively, are estimated by employing modified Becke-Johnson (mBJ) potential in the Wien2k computational program. The calculated optical characteristics such as dielectric coefficient, refractive index, absorption, reflection, energy loss coefficient and other related parametric quantities are explored to observe optoelectronic applications from UV to visible energy range as we move from Zn to Hg. Moreover, the ratios of thermal conductivity to electrical conductivity, Seebeck coefficient along with the figure of merits (ZT) are discussed to acknowledge the thermoelectric behavior of all three materials. The high values of ZT 0.84/0.74/0.79 are observed for Zn/Cd/HgIn2S4 spinel sulfides which ensure their prospective use in thermal energy conversion devices, especially in thermoelectric generators.

Este artigo discorre sobre a trajetória do Coletivo NegreSer (Belo Horizonte/MG) e suas ações artístico/pedagógicas antirracistas, escancarando a colonialidade na formação em dança no ensino superior. Numa interseccionalidade da Arte, Educação e Ciência Sociais, analisou-se implicações da cultura, currículo e colonialidade revelando o etnocentrismo europeu como fonte epistêmica quase exclusiva dos processos educativos em dança no contexto investigado. Por meio de pesquisa narrativa, valendo-se de métodos autobiográficos, reconstitui-se a implementação da agência des jovens negres do Coletivo, bem como as estratégias e dispositivos metodológicos em dança por elas desenvolvidas, contribuindo para o campo de conhecimento das artes cênicas, recusando processos curriculares colonizados e colonizadores.
Eu não sou esgoto do gozo alheio
Authors: Cunha Liana da
Published: June 2022

Este artigo emerge do desejo de partilhar os processos e os procedimentos que resultaram na performance Eu não sou esgoto do gozo alheio. Esta célula de movimento integra o videodança Terrorismo poético: Pequenas ações para encantar a quebrada, do grupo Fragmento Urbano (Guaianases, São Paulo/SP). Como fio condutor deste processo criativo, o aborto e a prática de stealthing permearam as reflexões, as práticas e a criação, amarradas em experiências pessoais, bem como, das mulheres negras da minha família. Entre as pretagogias do percurso estão a improvisação em dança, diários de bordo e registros através de imagens e vídeos. Como resultado, está a apresentação no 13º Visões urbanas: Festival internacional de dança em paisagens urbanas. Relatos de amigas e notícias veiculadas pelas mídias, também auxiliaram a abordar este assunto de maneira, crítica, sensível e poética, na tentativa de ressignificar violências e traumas em dança e possibilidades de cura.
Laboratório de artes cênicas na socioeducação.
Authors: De Souza José , De Andrade Bareicha Paulo Sérgio
Published: June 2022

Dissertação de mestrado em arte do autor realizada na Universidade de Brasília. Discorre sobre o processo criativo em artes cênicas que concebi como professor-artista-pesquisador no laboratório de narrativas e teatralidades na socioeducação. O objetivo deste artigo é desenvolver uma pedagogia teatral para jovens em conflito com a lei na XXX. Os dados foram coletados por meio da análise de conteúdo das narrativas teatralizadas desses jovens e da escuta sensível às suas inquietações. No período entre fevereiro de 2019 e março de 2020 os socioeducandos teatralizaram suas narrativas em quadros cenográficos sobre liberdade, aprisionamento e geracionalidade. Deste ponto, construiu-se uma pedagogia socioeducativa com as artes cênicas. A perspectiva conceitual-metodológica abrange diálogos entre o sociodrama de Moreno e a performance de Goffman nos campos de estudo da cena. Eles possuem em comum uma teoria de papéis específica ao contexto da pesquisa. A problemática do estudo circunscreveu uma transversalidade entre sociologia e teatro: quais são os vínculos entre as cenas narradas e as mesmas cenas, teatralizadas? As discussões dos resultados e suas considerações finais recomendam processos criadores estético-cênicos a partir dos estudos da cena como campo aberto à diversificação de olhares: texto vivo, quadros cenográficos e o ator-narrador.

Corpo, voz, palavra e poder
Authors: De Souza Newton Armani
Published: June 2022

Artigo apresentando o resultado da aplicação da descrição do discurso proposta por Michel Foucault à análise de uma obra sobre a História do Teatro brasileiro, com atenção ao tratamento oferecido à negritude. Os enunciados apresentados pelo autor exaltam um homem negro alforriado, como primeiro ator brasileiro reconhecido como tal, na mesma maneira que consideram que o negro desaparece dos palcos, após o século XIX. Partindo dos mesmos argumentos, mas pensando o Teatro para além da dramaturgia, fomos capazes de provar o contrário, em especial considerando o corpo como elemento central do fazer do teatral, ao invés da palavra escrita.

Capítulo 7. Vías de financiación en los medios nativos digitales
Authors: Vara-Miguel Alfonso , Breiner James G.
Published: June 2022

El hundimiento de las ventas e ingresos de los productos impresos, la caída de los ingresos publicitarios en medios convencionales, la concentración de la inversión publicitaria digital en torno a actores como Google o Facebook, y la resistencia al pago por noticias digitales de la mayoría de los españoles, evidencian la necesidad de buscar otras fuentes de financiación para los medios. Este estudio revisa las fórmulas de ingresos utilizadas por los medios nativos digitales para el sostenimiento económico de las empresas informativas.

Authors: Andriani Rezah
Published: June 2022

Masalah gizi (Kekurangan Energi dan Protein) dan stunting dapat terjadi karena salah satu factor penyebab yaitu pemberian MP-ASI yang kurang tepat. MPASI adalah makanan dan minuman yang diberikan kepada anak usia 6–24 bulan untuk pemenuhan kebutuhan gizinya. Upaya yang sudah dilakukan untuk menurunkan angka kejadian stunting yaitu dengan memberikan pendidikan kesehatan tentang MPASI. Metode pendidikan dengan menggunakan multimedia/ aplikasi dapat dijadikan sebagai sebuah alternatif pendidikan kesehatan tentang MPASI. Edukasi dengan menggunakan aplikasi dinilai lebih efektif dan efisien dari pada edukasi secara tatap muka. Untuk itu peneliti akan melakukan pengabdian masyarakat berupa pendidikan kesehatan Aplikasi Makanan Pendamping ASI (MPASI). Aplikasi ini dibuat untuk mempermudah ibu-ibu dalam mengakses informasi mengenai MPASI. Kegiatan pengabdian masyarakat ini dilaksanakan di Desa Kelampaian Kecamatan Rantau Alai Kabupaten Ogan Ilir pada tanggal 28 Januari 2022, dengan mensosialisasikan aplikasi MPASI kepada ibu-ibu yang mempunyai anak berusia 6 bulan-24 bulan sebanyak 15 orang sebagai salah satu solusi mendapatkan informasi mengenai MPASI dengan benar, praktis, efektif dan efisien. Peserta diajarkan cara menggunakan Aplikasi MPASI. Hasilnya semua peserta (100%) dapat menggunakan Aplikasi MPASI dengan benar.

Authors: Belfar Assia , Bensaci Cheyma , Belguidoum Mahdi
Published: June 2022

In this study we used spectrophotometrical techniques to estimate antioxidant efficacy by using 2,2-diphenyl-1-picrylhydrazyl free radical scavenging capacity and reducing power capacity. We have used also electrochemical techniques performed by cyclic voltammetry. The present study examined the antioxidant activities of the methanolic extract (ME) of date palm (Phoenix dactylifera. L) fruits (DPF) of four native cultivars from Algeria, namely, Ghars (Gh), Chtaya (Cht), Degla Beïda (DB) and Tinissine (Tns). Quantitative estimation of total phenol and flavonoid content by a colorimetric assay showed that methanol extracts are rich in these components. The content of total phenolics of different cultivars extracts was in the range of 26.083 - 35.850 GAE/100g DW. while it was the content of total flavonoids of the different cultivars extracts was in the range of 5.276 - 6.055 QE/100g DW. The value of IC50 for DPPH radical test ranged from 0.193 to 0.400mg/ml. All extracts showed very good activity of ferric reducing power, the higher power was in methanolic extract of Tns. The less IC50 value in cyclic voltammetry method (CV), which meet the highest effective antioxidant was 0.121 mg/ml in methanolic extract of Tns.
