Published: August 2022

Purpose: This study examined determinants of students’ examination corruption at the College of Distance Education (CoDE), University of Cape Coast (UCC), Ghana.

Methodology: The participants of the study included students, Regional Coordinators (RCs), and staff of the Examination Unit at CoDE. A sample of 252 students was selected from an accessible population of 3,095 using a proportionate stratified sampling technique. The questionnaire and semi-structured interviews were used to collect data. Data were analysed with frequency and percentage counts, standard deviations, and presented in tables supported with transcribed views expressed by the RCs and the Head of Exams Unit (HEU).

Findings: The study's findings revealed that examination malpractice was perceived to be a common illegal behaviour among students. The study also found that deviant students engage in examination malpractices at CoDE due to inadequate preparation for examinations.

Unique contribution to theory, practice and policy: It was recommended that the management of the college should sensitise all stakeholders, particularly candidates on the sanctions stipulated in their Students’ Handbook for culprits of examination corruption related activities. Also, the college should make study materials available to students on time to fully prepare for all exams.

Authors: Velásquez Ccosi Percy , Málaga Juárez Jorge
Published: August 2022

En primer lugar, se realiza un estudio teórico sobre la materia prima y la tecnología que implica la obtención de la fibra, para desarrollar un material similar al cuero, luego se tuvo que implementar una desfibradora mecánica en base a la secuencialidad y retroalimentación, con la aplicación de principios de ensayo-error y la ingeniería inversa; que con el uso del software de modelamiento mecánico CAD Solidworks 2018 proporcionó el diseño de elementos de máquinas agroindustriales, la validación y optimización en función de sus requisitos operacionales, alineados a las normas vigentes internacionales de la ingeniería de materiales, para la construcción y operación de la máquina. Se caracterizó la calidad del desfibrado teniendo en cuenta la limpieza de las fibras, el cual decrece exponencialmente dentro de los límites investigados con respecto a la holgura del desfibrado, haciéndose mayor para distancias menores a 1 mm. Para una distancia de desfibrado de 1 mm las fibras quedan lo suficientemente limpias, sin embargo, para una distancia de desfibrado de 1,5 mm las fibras obtenidas no pueden ser utilizadas debido a la gran cantidad de material no fibroso que aún se encuentra adherido a las mimas. Con la desfibradora se extrae una importante cantidad de celulosa de las hojas, ideal para convertirlas en un material flexible, resistente y ecológico alternativo al cuero de origen animal sustentable al uso a los desechos producidos durante la cosecha de esta fruta. La versatilidad de este material permite desarrollar una gran variedad investigaciones dirigidas a la producción de carteras, bolsos, tapizados, calzados y demás accesorios que se pueden manufacturar en cuero.

El objetivo fue evaluar la suplementación alimenticia con harina de maca sobre las características seminales en verracos de la Granja “Quri Cuchi”, Ayacucho. Cuatro verracos de diferentes genotipos con 203,9 ± 50.1 kg en promedio, fueron desparasitados y suplementados con 250 mg de maca negra/Kg/35 días. El día cero (D00) representó el control y los días D07, D14, D21, D28 y D35 a los tratamientos. Se colectó semen para su evaluación macro y microscópicamente. El semen colectado tuvo un color opalescente a lechoso, pH 7, densidad de 1 a 2 y sin olor anormal. Las colecciones/semana/verraco total fueron 1.5 ± 0.4 veces y sin diferencias significativas (P=0.90). El tiempo de colección demandó 5.7 ± 1.5 minutos, similar (P>0.05) entre el D00 y los días D07, D14, D21, D28, D35. El peso y el volumen total del eyaculado fueron 138.4 ± 12.8 g y 135.6 ± 12.5 ml, respectivamente, los cuales no difirieren entre D00 y D07 (P=0.72), D14 (P=0.23), D21 (P=0.11), D28 (P=0.07) y D35 (P=0.14). La concentración espermática total fue 661.0 ± 219.3 x 106 spz/ml, sin diferencia (P>0.05) entre el D00 versus los días de tratamiento. La motilidad individual total (88.9 ± 2.4%) mejoró (P=0.07) al compararse D00 con D35. La vitalidad total (78.5 ± 4.9%), las anormalidades (1.9 ± 0.7%) e integridad de membrana (63.6 ± 3.5%), fueron similares al D00 (P>0.05). En conclusión, las características seminales no se ven mejoradas mediante la suplementación con harina de maca, aunque el volumen tuvo una tendencia a la mejora.

Published: August 2022

Debido a la necesidad de optimizar el agua, se estudia a la diatomita, poco explorado en agricultura. La diatomita, roca sedimentaria de origen orgánico, aporta sílice y posee elevada porosidad y superficie específica. En Ayacucho la diatomita o “Quicato” de elevado contenido de silicio, porosidad superior al 80% y muy poco contaminante, podría emplearse en la actividad agrícola. Se evaluó en condiciones de laboratorio la aplicación de dosis de diatomita (0, 5, 10 y 15% v/v) de 2 mm, en dos suelos, de textura franco arcillo arenosa (Fr.Ar.A.) y franco arenosa (Fr.A.) de Luricocha - Huanta, a fin de valorar sus efectos sobre las propiedades físicas entre ellas la capacidad de campo, densidad aparente, densidad real y porosidad total de los suelos. Luego de incubar conservando a capacidad de campo los suelos durante seis meses, se encontró que incorporar 5, 10 y 15 % (v/v) de diatomita, aumenta significativamente la capacidad de campo en 2.87%, 8.39%, 9.87% (Fr.Ar.A) y 3.14%, 6.46%, 9.77% (Fr.A.), respecto al testigo. 15% (v/v) de diatomita en suelo Fr. A, disminuye respecto al testigo en 5.20%, la densidad aparente y en 9.66% la porosidad total. En suelo Fr.Ar.A., no influyen significativamente en ambos parámetros, sin embargo, muestra tendencia creciente en poros totales. La densidad real en ambos suelos, disminuye linealmente con las dosis de diatomita, de 2.56 a 2.38 g.cc-1 en Fr.A. y 2.48 a 2.40 g.cc-1 en Fr.Ar.A.

Para evaluar el efecto de las aguas de riego con detergente en la germinación y crecimiento de cinco especies de leguminosas (lenteja, arveja, frejol, haba y garbanzo), se diseñó un experimento en Bloques Completamente Randomizado con cuatro tratamientos (A=0,5 gr/L, B=1 gr/L, C=1.5 gr/L y D=2.5 gr/L) más dos testigos (agua potable y agua fertilizada) y tres repeticiones/tratamiento. Las diferencias de crecimiento se realizaron con mediciones de la radícula, tallo, y número de hojas. La germinación se cuantificó cada 12 h y se consideró ocurrida cuando la radícula había emergido y tenía longitud de 1 cm. Se encontraron diferencias significativas (p<0,05) en el porcentaje de germinación de las semillas de “lenteja” y “garbanzo” por efecto de las concentraciones del detergente que corresponden al tratamiento D (2,5 gr/L). El crecimiento del tallo por efecto del tratamiento B, y considerando las especies el más significativo fue la “lenteja”. Se encontraron diferencias significativas (p<0,05) en la longitud de la radícula por efecto del tratamiento y por especie. Las longitudes de la radícula tienen mayor significación estadística por efecto de los tratamientos A, C y D. De las especies destacaron el “frejol”, “arveja” y “haba”. Con número de hojas se encontraron diferencias significativas (p<0,05) según los tratamientos y especies. El incremento del número de hojas fue mayor con el uso del “agua potable” y en cuanto a la especie predominó el “frejol”.

Published: August 2022

Data penetration during transmission is one of the key issues with communication technology. In this work, a protected significant communication system combining a variety of chaotic and direct-sequence/spread-spectrum DS/SS approaches is proposed. This is an excellent piece of work. The bit value in this system varies according to chaotic behavior, but it really is a multiple of the process of communication's fixed chip duration. Input signals of varying duration were frequency band by multiplication simultaneously with a pseudo noise (PN) pattern and then manipulated onto harmonic carriers using quadrature phase shift keying (QPSK). The tent map is used by the MATLAB software over a time range of 0 to 1200 seconds. Three sample periods were taken from the time domain duration for each of the four areas S1, S2, S3 and S4. The results of simulations and numerical simulations are presented to demonstrate the system's dependability and viability

Technology has also influenced various sectors, an example of technological development is the emergence of application software that makes it easier for companies.But not only that, one type of form of technology that is growing rapidly in the era of pademi is information and Communication Technology in the field of Education. With the existence of social media, the younger generation takes advantage of this to take part and influence the community by showing their intelligence to set an example to the community through social media. One of the things that need to be considered in creating a competitive advantage for culinary, fashion, music, tourism industry players in the pademi era is Database Building and Management, namely the application of a platform that includes WhatsApp Business and email lists as a data container for potential repeat purchases by consumers. Since the pandemic conditions, consumers prefer to buy food, clothing, household items dal other delivery rather than come on the spot. Adaptation for behavior towards the new normal by developing strategies such as social distancing, health consider, cashless, less contact must also be implemented by existing businesses. In the context of business, technology can provide changes so as to create a new point of view in business known as digital marketing or internet marketing that utilizes the internet as a market medium. Conventional businesses are more concerned with purchases made by consumers. However, with a circular business model, how consumers can obtain goods and services is more important. Conventional business success focuses more on the material benefits gained from the sale of goods or services. They are result oriented. However, circular businesses are more concerned with how they can create a balance between environmental, social, and profit aspects.

Dynamical perturbation of the stratosphere by a pyrocumulonimbus injection of carbonaceous aerosols
Authors: Doglioni Giorgio , Aquila Valentina , Das Sampa , Colarco Peter R. , Zardi Dino
Published: August 2022

Abstract. The Pacific Northwest Pyrocumulonimbus Event (PNE) took place in British Columbia during the evening and nighttime hours between 12 and 13 August 2017. Several pyroconvective clouds erupted on this occasion, and released in the upper troposphere and lower stratosphere unprecedented amounts of carbonaceous aerosols (300 ktn). Only a few years later, an even larger pyrocumulonimbus (pyroCb) injection took place over Australia. This event, named “the Australian New Year (ANY) event”, injected up to 1100 ktn of aerosol between 29 December 2019 and 4 January 2020. Such large injections of carbonaceous aerosol modify the stratospheric radiative budgets, locally perturbing stratospheric temperatures and winds.
In this study, we use the Goddard Earth Observing System Chemistry Climate Model (GEOS CCM) to study the perturbations on the stratospheric meteorology induced by an aerosol injection of the magnitude of the PNE. Our simulations include the radiative interactions of aerosols, so that their impact on temperatures and winds are explicitly simulated. We show how the presence of the carbonaceous aerosols from the pyroCb causes the formation and maintenance of a synoptic-scale stratospheric anticyclone. We follow this disturbance considering the potential vorticity anomaly and the brown carbon aerosol loading and we describe its dynamical and thermodynamical structure and its evolution in time.
The analysis presented here shows that the simulated anticyclone undergoes daily expansion–compression cycles governed by the radiative heating, which are directly related to the vertical motion of the plume, and that the aerosol radiative heating is essential in maintaining the anticyclone itself.
The control of short-term ice mélange weakening episodes on calving activity at major Greenland outlet glaciers
Authors: Wehrlé Adrien , Lüthi Martin P. , Vieli Andreas
Published: August 2022

Abstract. The dense mixture of iceberg of various sizes and sea ice observed in many of Greenland's fjords, called ice mélange (sikussak in Greenlandic), has been shown to have a significant impact on the dynamics of several Greenland tidewater glaciers mainly through the seasonal support it provides to the glacier terminus in winter. However, a clear understanding of shorter-term ice mélange dynamics is still lacking, mainly due to the high complexity and variability of the processes at play at the ice-ocean boundary. In this study, we use a combination of Sentinel-1 radar and Sentinel-2 optical satellite imagery to investigate in detail intraseasonal ice mélange dynamics and its link to calving activity at three major outlet glaciers: Kangerdlugssuaq Glacier, Helheim Glacier and Sermeq Kujalleq in Kangia (Jakobshavn Isbræ). In those fjords, we identified recurrent ice mélange weakening (IMW) episodes consisting in the up-fjord propagation of a discontinuity between jam-packed and weaker ice mélange towards the glacier terminus. At a late stage, i.e. when the IMW front approaches the glacier terminus, these episodes were often correlated with the occurrence of large-scale calving events. The IMW process is particularly well visible at the front of Kangerdlugssuaq glacier and presents a cyclic behavior, such that we further analyzed IMW dynamics during the June–November period from 2018 to 2021 at this location. Throughout this period, we detected 30 IMW episodes with a recurrence time of 24 days, propagating over a median distance of 5.9 km and for 17 days, resulting in a median propagation speed of 400 m/d. We found that 87 % of the IMW episodes occurred prior to a calving event visible in spaceborne observations and that ~75 % of all detected calving events were preceded by an IMW episode. These results therefore present the IMW process as a clear control on the calving activity of Kangerdlugssuaq glacier. Finally, using a simple numerical model for ice mélange motion, we showed that a slightly biased random motion of ice floes without fluctuating external forcing can reproduce IMW events and their cyclic influence, and explain observed propagation speeds. These results further support our observations in characterizing the IMW process as self-sustained through the existence of an IMW-calving feedback. This study therefore highlights the importance of short-term ice mélange dynamics in the longer-term evolution of Greenland outlet glaciers.
Observing system simulation experiments reveal that subsurface temperature observations improve estimates of circulation and heat content in a dynamic western boundary current

Abstract. Western boundary currents (WBCs) form the narrow, fast-flowing poleward return flows of the great subtropical ocean gyres and are sources of
rapidly varying mesoscale eddies. Accurate simulation of the vertical structure, separation latitude, and ocean heat content of WBCs is important
for understanding the poleward transport of heat in the global ocean. However, state estimation and forecasting in WBC regions, such as the East
Australian Current (EAC), the WBC of the South Pacific subtropical gyre, is challenging due to their dynamic nature and lack of observations at
depth. Here we use observing system simulation experiments to show that subsurface temperature observations in a high eddy kinetic energy region
yield large improvement in representation of key EAC circulation features, both downstream and ∼ 600 km upstream of the observing
location. These subsurface temperature observations (in concert with sea surface temperature and height measurements) are also critical for
correctly representing ocean heat content along the length of the EAC. Furthermore, we find that a more poleward separation latitude leads to an EAC
and eddy field that is represented with far reduced error, compared to when the EAC separates closer to the Equator. Our results demonstrate the
importance of subsurface observations for accurate state estimation of the EAC and ocean heat content that can lead to marine heatwaves. These
results provide useful suggestions for observing system design under different oceanographic regimes, for example, adaptive sampling to target high
energy states with more observations and low energy states with fewer observations.
Modelling geographical and built-environment attributes as predictors of human vulnerability during tsunami evacuations: a multi-case-study and paths to improvement
Authors: León Jorge , Gubler Alejandra , Ogueda Alonso
Published: August 2022

Abstract. Evacuation is the most important and effective method to save human lives during a tsunami. In this respect, challenges exist in developing quantitative analyses of the relationships between the evacuation potential and the built-environment and geographical attributes of coastal locations. This paper proposes a computer-based modelling approach (including inundation, evacuation, and built-environment metrics), followed by multivariate regressive analysis, to estimate how those attributes might influence the expected tsunami death ratios of seven Chilean coastal cities. We obtained, for the examined variables, their average values to different thresholds of the death ratio. Also, our statistical analysis allowed us to compare the relative importance of each metric, showing that the maximum flood, the straightness of the street network, the total route length, and the travel time can have a significant impact on the expected death ratios. Moreover, we suggest that these results could lead to spatial planning guidelines for developing new urban areas into exposed territories (if this expansion cannot be restricted or discouraged) or retrofitting existing ones, with the final aim of enhancing evacuation and therefore increasing resilience.
Numerical simulation of contemporary kinematics at the northeastern Tibetan Plateau and its implications for seismic hazard assessment

Published: August 2022

Abstract. The slip rates of active faults in the northeastern Tibetan
Plateau (NETP) require clarification to understand the lateral expansion of
the Tibetan Plateau and assess the seismic hazards in this region. To obtain
the continuous slip rates of active faults at the NETP, we constructed a
three-dimensional (3D) numerical geomechanics model that includes a complex
3D fault system. The model also accounts for the physical rock properties,
gravity fields, fault friction coefficients, initial stress, and boundary
conditions. Following this, we present the long-term kinematics of NETP based on the
horizontal and vertical velocities and fault slip rates acquired from the
model. The fault kinematic characteristics indicate that the Laohushan,
middle–southern Liupanshan, and Guguan–Baoji faults, as well as the
junction area of the Maxianshan and Zhuanglanghe faults, are potential
hazard areas for strong earthquakes. However, as these faults are currently
in the stress accumulation stage, they are unlikely to cause a strong
earthquake in the short term. In contrast, it is likely that the
Jinqiangshan–Maomaoshan fault will generate a earthquake with a surface-wave magnitude (MS) of 7.1–7.3
in the coming decades. In addition, the velocity profiles across the NETP
imply that the plate rotation is the primary deformation mechanism of the
NETP even though the intra-block straining and faulting are non-negligible.

Published: August 2022

Purpose: This study aimed to compare the effect of smoking cigarettes and drinking beverages and also polishing procedures on the discoloration of CAD/CAM materials.
Materials and Methods: Resin nanoceramic (Lava Ultimate-RN), feldspar ceramic (CEREC Blocs Ceramics-FC) and lithium disilicate glass-ceramic (IPS e.max® CAD-LDC) specimens (5X5 X2 mm) were used for this study. Initially, baseline surface roughness (Ra) and color values (L*, a*, b*) of the specimens were measured with profilometer and chroma meter. Then the specimens were exposure nicotine, coffee and red wine. The first discoloration values of each specimen were measured. Then, all of the specimens were subjected to re-polishing procedures. Than, the surface roughness and color values of each specimen were measured. The specimens were subjected to the same staining process again. After exposure of the specimens to the staining agents, the second staining value was measured. Two-way analysis of variance (ANOVA) was used for normally distributed groups, and the Kruskal-Wallis test was used for non-normally distributed groups.
Results: Statistically significant ΔE* values were observed for RN (8.26±1.55) and FC (7.69±1.52) for nicotine in the first staining group. The maximum total color changes were observed in the nicotine group for all of the material specimens. Nicotine caused the highest color changes on the test materials than coffee and wine. Surface roughness did not show a statistically significant difference based on the staining agents for any of the materials within a group (p<0.05).
Conclusions: It was observed that nicotine staining is far stronger than beverage staining.

Published: August 2022

Purpose: The study aimed to investigate the effect of applying flowable compomer using different techniques and long-term water storage on microtensile bond strength (µTBS) to primary teeth dentin and present a comparison with packable compomer.
Materials and methods: 90 primary molars were used to evaluate the µTBS of the materials. Specimens were randomly divided into 3 main groups for restoration: Group 1 and 4, compomer (Glasiosite, VOCO GmbH, Cuxhaven, Germany) filling alone; Group 2 and 5, flowable compomer (Twinky Star Flow, VOCO GmbH, Cuxhaven, Germany) lining/pre-cured and overlaying compomer; and Group 3 and 6, flowable compomer lining/co-cured with overlaying compomer. All specimens were thermocycled (500X), after which half of them (n=45) were stored in distilled water for 24 h (Group A: Groups 1-3), and the remaining half (n=45) for 24 months (Group B: Groups 4-6). Samples were tested for µTBS (1 mm/min) with a microtensile testing machine (T 61010 Ki, Bisco, Schaumburg, USA). Failure modes were determined with the aid of a stereomicroscope. Results were analyzed using the Kruskal-Wallis H test.
Results: There was no statistically significant difference between the groups regarding bond strength (p>0.05). Mixed cohesive failure of both adhesive and dentin was the most common type of failure in all groups (p<0.05). 2-year water storage significantly decreased the bond strength for all groups (p<0.05).
Conclusion: Flowable compomers applied using different techniques produced similar bond strength to dentin compared to compomer. However, long-term water storage decreased bond strength significantly.

Published: August 2022

Em resumo, a anemia hemolítica autoimune (AHAI) é uma doença que se caracteriza pela destruição dos glóbulos vermelhos causada pelos próprios anticorpos do organismo, os chamados “autoanticorpos”. Existem três tipos diferentes de anemia hemolítica: quente, fria e mista.Anemia hemolítica quente: os autoanticorpos conseguem reagir mais fortemente à temperatura corporal de 37°C.Anemia hemolítica fria: destruição dos glóbulos vermelhos acontece a temperaturas entre 4ºC e 18ºC.Anemia hemolítica mista: os dois tipos de autoanticorpos (quente e frio) coexistem.As anemias hemolíticas são definidas como um grupo de anemias cuja característica principal é a diminuição da sobrevida eritrocitária. Embora o tempo na circulação até a morte das hemácias velhas ou senescentes em adultos seja de 110 a 120 dias, e da anemia hemolítica seja definida por uma sobrevida eritrocitária menor do que 100 dias.
Reflexões (quase) antropofágicas sobre remunerações desiguais de docentes no Brasil e nos Estados Unidos da América (do Norte)
Authors: Gouveia Andréa Barbosa , Fischman Gustavo E.
Published: August 2022

O artigo analisa a remuneração de professores no Brasil e nos Estados Unidos da América (do Norte) a partir de uma proposta de diálogo comparado não valorativo e em sintonia com perspectivas pós-coloniais. A ideia de (quase) antropofagia justifica-se na percepção que é possível um diálogo internacional a partir de um olhar dos problemas do Sul Global para a agenda de pesquisa. Utiliza fontes públicas sobre remuneração da Relação de Informações Sociais (RAIS) do Brasil e dados do Schools and Staffing Survey (SASS) dos Estados Unidos, de 2020. Entre as conclusões, indica que os debates no Brasil que consideram a experiência estadunidense nas políticas educacionais superdimensionam as políticas de mérito/bônus e desconsideram outros elementos que marcam o debate nos Estados Unidos em termos de desigualdades na profissão docente, tais como acúmulo de outros empregos além da docência, jornada laboral mais extensa, variação salarial em diferentes estados/municípios/distritos.

Published: August 2022

Esta investigação tem como principal escopo compreender as relações dialécticas entre o esquecimento e a memória. Nesse sentido, procura analisar o fundamento antropológico do esquecimento e as formas do qual se reveste. De modo semelhante, intenta investigar as bases essenciais da memória e a sua ligação a determinados objectos físicos, encarados como meio de revestir uma certa forma de redenção, ou, pelo menos, de libertação das inegáveis energias negativas associadas a qualquer fenómeno de violência.
conceitos morrem?
Authors: Fruteau de Laclos Frédéric
Published: August 2022

Os conceitos científicos, mesmo usados, mesmo desusados, nunca são definitivamente perimidos. Eles sempre podem retornar em conjecturas teóricas posteriores. Isso se deve à natureza muito particular do conceito, irredutível às descrições positivistas: ainda que procedentes da experiência e tendo por vocação dar-lhe razão, os conceitos representam muitos desenraizamentos e sobrevoos explicativos da experiência. Epistemólogos antipositivistas do século XX foram atentos a tais características filosóficas. Expomos aqui seu modelo da conceitualização científica e o empregamos em um caso, o conceito de tendência: mostramos que ele sobrevive ao período de sua primeira formulação e que merece retornar nos debates psicofisiológicos contemporâneos.
Incorporating Equity Into Maternal Telehealth
Authors: Movitz Sabrina , Mayer Rachel , Dingwall Alison
Published: August 2022

The US maternal health crisis continues to disproportionately affect economically and socially marginalized pregnant and postpartum people. Meanwhile, telehealth has boomed in popularity due to the coronavirus pandemic and has been lauded as a potential tool to address certain social determinants of health (SDOHs) such as transportation and rurality. While telehealth shows promise for obstetric care delivery, more research is needed to assess accessibility and outcomes in diverse populations. This commentary outlines key areas for health care providers and researchers to advance maternal health equity through telehealth by addressing individual patient needs, investing in telehealth care delivery, using electronic health record data to identify demographic trends, and conducting equity-centered research focused on SDOHs for pregnant and postpartum people.

While we use pregnant and postpartum people where possible here to recognize that not all pregnant people identify as women, we occasionally use women and maternal to reflect terminology used in federal, state, and local data.1 Additionally, we use the term telehealth in accordance with the definition by the US Department of Health and Human Services.2
