Published: September 2022

With the use of cryogenic deformations by rolling and quasi-hydroextrusion, as well as annealing up to 723 K, various structures, including nanometer ones, were created in ultrafine-grained (UFG) titanium alloy of the VT6 grade, and mechanical and dissipative properties were studied. The deformation regimes for the formation of a nanostructured state with a high level of strength characteristics without loss of plasticity are established. The revealed features of the temperature dependences in the range of 100…600 K of internal friction and shear modulus in the nanostructured state in comparison with the UFG state are analyzed.

Authors: Alvarez Osegueda Alejandra Leonor
Published: September 2022

OBJETIVO: determinar los niveles de efectividad del proceso docente en el desarrollo de habilidades para la vida. MÉTODO: el enfoque de la investigación fue cuantitativo, con alcance descriptivo - correlacional, de diseño no experimental y corte transversal, la población de estudio estuvo conformada por estudiantes graduandos del ciclo escolar 2021 y una muestra de 835.  El muestreo fue no probabilístico por cuotas.  Se utilizó la técnica de encuesta en línea autoadministrada.  Se utilizó como instrumento un cuestionario de proceso docente y un test de habilidades para la vida. RESULTADOS: el proceso docente tiene incidencia en el desarrollo de habilidades para la vida en un nivel de significancia de ,650; esto confirma la hipótesis que los elementos del proceso docente aportan significativamente al desarrollo de habilidades para la vida, lo cual es favorable a pesar de mostrar una alta presencia de la educación tradicional dentro del proceso docente. CONCLUSIÓN: los estudiantes se encuentran en un nivel medio del desarrollo de habilidades para la vida, es decir, los estudiantes si cuentan con habilidades para la vida, pero no necesariamente son capaces de hacer uso de ellas para afrontar los desafíos de la vida diaria porque no fueron formados para tal situación.

Authors: Plachot González Graciela B.
Published: September 2022

OBJETIVO: Aportar a la meta cognición de las posiciones docentes en las aulas virtuales en tiempos de pandemia, desmantelando la ficción de lo dado-naturalizado en la presencialidad. MÉTODO: análisis documental. RESULTADOS: en estos procesos se pueden identificar cuatro categorías diversas en las formas de transitar su enseñanza, de pensar los aprendizajes, planificar y evaluar: la ecolalia, el súper héroe, la re-invención y el retiro. Éstas contribuyen a la fragilidad o la potenciación de la calidad educativa, la mejora de la enseñanza y la salud integral de los actores educativos. CONCLUSIÓN: la continuidad de las aulas en la virtualización forzada transformó las prácticas docentes. La metacognición del hacer del docente es relevante en la proyección de los escenarios de enseñanza pos-pandémicos. El cambio de paradigma comunicacional y didáctico demanda la revisión constante del rol y de la vocación en la enseñanza universitaria. Este ensayo es producto de un seminario doctoral, en el Doctorado en Educación de la Escuela de Posgrado de la Facultad de Humanidades de la Universidad San Carlos de Guatemala. Parte de su contenido fue compartido en forma oral como ponencia magistral en el III Encuentro Internacional de Psicología en la Universidad Veracruzana, México.

Authors: Álvarez-García Horacio Balam , Ramírez-Muñoz Augusto Abdiel
Published: September 2022

El insomnio se perfila como el trastorno de sueño con mayor prevalencia durante el confinamiento por COVID-19, generando una disminución en la calidad de vida de quien lo padece. El presente estudio muestra el caso clínico de un hombre de 37 años que tras modificar sus patrones de sueño por los horarios de trabajo desarrolló un cuadro de insomnio crónico. El problema inició cuando el paciente incrementó su horario laboral, por lo que comenzó a prolongar su hora de acostarse hasta las 2:00am, sin embargo, las actividades laborales iniciaban a las 7:00 am, dando como resultado somnolencia durante el día. Tras la entrevista inicial se implementó Tratamiento Conductual Breve en Insomnio (TCBI). Los componentes fueron: restricción de tiempo en cama, terapia de control de estímulos, higiene de sueño y relajación muscular progresiva. La duración fue de cinco sesiones semanales divididas en, una de evaluación, tres de intervención y una de cierre. En los resultados se observa un incrementó en: tiempo subjetivo de sueño, calidad de sueño; además de una disminución de la frecuencia y severidad de los síntomas de insomnio y somnolencia durante el día, tanto en el diario de sueño como en los instrumentos. Finalmente podemos concluir que la intervención fue clínicamente efectiva, aunque se sugieren mejoras en el diseño de investigación para futuros estudios

Authors: Zamudio Alejandro , Montero-López Lena María , García Cabrero Benilde
Published: September 2022

El propósito del presente estudio consistió en someter a prueba empírica tres modelos teóricos sobre la acción colectiva en el contexto del 8 de marzo en México. Las variables tomadas en cuenta fueron la identidad colectiva politizada, percepción, injusticia, obligación moral y eficacia colectiva y sus respectivos componentes emocionales. Con un diseño cuantitativo transversal, se validó mediante jueces expertos una matriz de especificaciones y se crearon los instrumentos para la presente investigación. Del 6 al 8 de marzo del 2021, y mediante publicidad pagada en Facebook, se obtuvo una muestra no probabilística de 870 mujeres de la Ciudad de México y zona conurbada, con edades de 18 a 68 años (M= 26.7). Mediante ecuaciones estructurales, el modelo que mejor ajustó fue en donde la identidad politizada y la eficacia colectiva afectiva influyeron de forma indirecta en la acción colectiva mediadas por la obligación moral (SRMR = 0.05, RMSEA=.08, GFI =.91 y CFI = .92, r2= .63). Se discute la importancia de las emociones y la obligación moral en la acción colectiva de mujeres en México.

*Fe de erratas:En el artículo titulado “Acción colectiva en el 8 de marzo, prueba empírica de tres modelos teóricos" vol 30, núm 1. se cita el estudio de Sabucedo et al. (2018) como un estudio de mediación, cuando en realidad los autores realizaron un modelo de regresión múltiple para predecir la acción colectiva por medio de la identidad colectiva, la percepción de injusticia, la eficacia colectiva y la obligación moral.

Published: September 2022

O Brasil está entre os 10 maiores produtores de aço do mundo. Apesar disso, o emprego de sistemas construtivos compostos por estruturas metálicas é pouco expressivo se comparado com o potencial do parque industrial brasileiro. Com o crescimento populacional e o avanço da tecnologia, vem sido estudadas alternativas construtivas que atendam a demanda atual, compatibilizando viabilidade econômica e técnica, à fim de se obter construções de baixo custo e ao mesmo tempo eficientes tecnicamente. Nos últimos anos, o Light Steel Framing (LSF) vem se tornado um método construtivo bastante explorado no mercado da construção civil. Por ser algo relativamente novo no país, ainda faltam ferramentas que possibilitam a modelagem e o dimensionamento das estruturas em LSF. Nesse contexto, o presente trabalho visa apresentar o sistema construtivo, sistematizando informações sobre os componentes do sistema além de um estudo de caso de habitação social aplicado à um software brasileiro de dimensionamento de estruturas em aço formadas à frio, comparando os resultados com a norma vigente ABNT NBR 14762/2010.

A Simple and High Throughput Methodology for Simultaneous Determination of Levodopa and Carbidopa
Authors: KIRLANGIÇ İrem , ÖZDOKUR Kemal Volkan , ERTAS Fatma Nil
Published: September 2022

Parkinson's disease (PD) is a degenerative disorder of the central nervous system. The motor symptoms of PD disease result from the death of dopamine-generating cells in a region of the mid brain and the dopamine precursor levodopa (L-Dopa) is used for the treatment. Carbidopa (Car) is administered in association with L-Dopa in pharmaceutical formulation as an inhibitor on the decarboxylase activity. Thus, their simultaneous determination is of great importance because of their co-existence in pharmaceutical preparations. Present study deals with a simple method development for simultaneous voltammetric determination of L-Dopa and Car at a pencil graphite electrode (PGE) via monitoring the reduction peak of L-Dopa and the second oxidation peak of Car. The sensitivity of the method was found comparable to other methods depending on the sophisticated electrode modifications and the limits of detection were calculated as sub micromolar levels.

Abstract. Comprehensive measurements are vital to obtain big enough datasets for better understanding the complex atmosphere and further improving the air quality. To investigate the year-to-year variabilities of air quality and influences of special events (Beijing Winter Olympics, COVID lockdown and Chinese New Year) on it during the wintertime in a polluted urban air, we conducted comprehensive observations in Beijing, China, during January 1st – February 20th, in the years from 2019 to 2022. The mass concentration of PM2.5 and its composition (organics, nitrate, sulfate, ammonium, chloride and black carbon), number size distributions of particles (down to ~1 nm) and ions, gaseous pollutants (CO, NOx, SO2, O3), condensable vapors (sulfuric acid and oxygenated organic molecules), as well as meteorological parameters were simultaneously measured. We selected the period before January 22nd without any special events in each year to show the year-to-year variabilities of the air quality. We found that the concentrations of PM2.5, black carbon, chloride, organics, CO, NOx, total oxygenated organic molecules and number concentration of sub 3 nm particles showed similar year-to-year variabilities, decreasing from 2019 to 2021 and then increasing in 2022. On the contrary, SO2 concentrations decreased year by year due to the significant emission reduction, leading to decreasing mass concentrations of sulfate and number concentration of sulfuric acid monomer and dimer from 2019 to 2022. As for the influence of special events, due to the favorable meteorological conditions together with reductions in anthropogenic emissions, there were basically no haze events during Beijing Winter Olympics. Although there was emission reduction also during the COVID lockdown period, especially for NOx, the enhancement of secondary inorganic aerosol formation, together with unfavorable meteorological conditions, caused severe haze events during this period. Additionally, these special events had only little impacts on the new particle formation processes. These results provide useful information to the development of more targeted pollution control plans.
TROPESS/CrIS carbon monoxide profile validation with NOAA GML and ATom in situ aircraft observations

Abstract. The new single-pixel TROPESS (TRopospheric Ozone and its
Precursors from Earth System Sounding) profile retrievals of carbon monoxide
(CO) from the Cross-track Infrared Sounder (CrIS) are evaluated using
vertical profiles of in situ observations from the National Oceanic and
Atmospheric Administration (NOAA) Global Monitoring Laboratory (GML)
aircraft program and from the Atmospheric Tomography Mission (ATom)
campaigns. The TROPESS optimal estimation retrievals are produced using the
MUSES (MUlti-SpEctra, MUlti-SpEcies, MUlti-Sensors) algorithm, which has
heritage from retrieval algorithms developed for the EOS/Aura Tropospheric
Emission Spectrometer (TES). TROPESS products provide retrieval diagnostics
and error covariance matrices that propagate instrument noise as well as the
uncertainties from sequential retrievals of parameters such as temperature
and water vapor that are required to estimate the carbon monoxide profiles.
The validation approach used here evaluates biases in column and profile
values as well as the validity of the retrieval error estimates using the mean and
variance of the compared satellite and aircraft observations. CrIS–NOAA GML
comparisons had biases of 0.6 % for partial column average volume mixing
ratios (VMRs) and (2.3, 0.9, −4.5) % for VMRs at (750, 511, 287) hPa
vertical levels, respectively, with standard deviations from 9 % to 14 %. CrIS–ATom comparisons had biases of −0.04 % for partial column and
(2.2, 0.5, −3.0) % for (750, 511, 287) hPa vertical levels, respectively,
with standard deviations from 6 % to 10 %. The reported observational
errors for TROPESS/CrIS CO profiles have the expected behavior with respect
to the vertical pattern in standard deviation of the comparisons. These
comparison results give us confidence in the use of TROPESS/CrIS CO profiles
and error characterization for continuing the multi-decadal record of
satellite CO observations.
Ionospheric Effects over the People’s Republic of China from the Super-Powerful Tropospheric Western Pacific Phenomenon of September–October 2018: Results from Oblique Sounding

Published: September 2022

Abstract. The paper deals with the effects that accompanied the Super Typhoon Kong-Rey action in the ionosphere over the People’s Republic of China (PRC). The observations were made using the Harbin Engineering University, PRC, multifrequency multiple path coherent software defined radio system. The typhoon began on September 29, 2018 and ceased to exist on October 6, 2018. The ionospheric response to the super typhoon action was clearly observed to occur both on October 1–2, 2018 (when the typhoon was 2,800–3,300 km from the propagation path midpoints and its energy gained a maximum value) and on October 5–6, 2018 when the typhoon was 1,000–1,500 km from the midpoints and its energy decreased by a factor of about 4. The ionospheric effects are more pronounced along the nearest propagation paths, whereas no effect was detected along the propagation path at the farthest distance from the typhoon. The super typhoon action on the ionosphere was accompanied by the generation or amplification of quasi-periodic variations in the Doppler shift by a factor of 2–3, as well as by noticeable variations in the signal amplitude. The Doppler spectra were observed to broaden in a number of cases. The period of wave perturbations exhibited variability in the ~20 min to ~120 min range, which suggests that the perturbations in the ionospheric electron density were caused by atmospheric gravity waves (AGWs) generated by the typhoon; in addition, the greater the AGW period, the greater the Doppler shift. As the period increased from 20 min to 120 min, the Doppler shift amplitudes increased from ~0.1 Hz to 0.5–1 Hz, whereas the amplitude of quasi-periodic variations in the electron density increased from a few to several tens of per cent within the same range of the AGW periods. The Doppler measurements have shown that the dusk terminator and super typhoon acted synergistically to amplify the ionospheric response to these sources of energy.
A climate-conditioned catastrophe risk model for UK flooding
Authors: Bates Paul D. , Savage James , Wing Oliver , Quinn Niall , Sampson Christopher , Neal Jeffrey , Smith Andrew
Published: September 2022

Abstract. We present a climate-conditioned catastrophe flood model for the UK that simulates pluvial, fluvial and coastal flood risks at 1 arc second spatial resolution (~20–25 m). Hazard layers for ten different return periods are produced over the whole UK for historic, 2020, 2030, 2050 and 2070 conditions using the UKCP18 climate simulations. From these, monetary losses are computed for Great Britain only for five specific global warming levels (0.6, 1.1, 1.8, 2.5 and 3.3 °C). The analysis contains a greater level of detail and nuance compared to previous work and represents our current best understanding of the UK’s changing flood risk landscape. Validation against historical national return period flood maps yielded Critical Success Index values of 0.65 and 0.76 for England and Wales respectively, and maximum water levels for the Carlisle 2005 flood were replicated to an RMSE of 0.41 m without calibration. This level of skill is similar to local modelling with site specific data. Expected Annual Damage in 2020 was £730M, which compares favourably to the observed value of £714M reported by the Association of British Insurers. Previous UK flood loss estimates based on government data are ~3x higher and lie well outside our modelled loss distribution, which is plausibly centred on the observations. We estimate that UK 1 % annual probability flood losses were ~6 % greater in the average climate conditions of 2020 than for the period of historical river flow and rainfall observations (centred approximately on 1995) and can be kept to around ~8 % if all countries’ COP26 2030 carbon emission reduction pledges and ‘net zero’ commitments are implemented in full. Implementing only the COP26 pledges increases UK 1 % annual probability flood losses by ~23 % above recent historical values, and potentially ~37 % if climate sensitivity turns out to be higher than currently thought.

Abstract. This study presents a simulation framework for cloud and precipitation measurements via spaceborne millimeter wave radar composed of nine sub modules. To demonstrate the influence of the assumed physical parameters and optimizing the microphysical modeling of the hydrometeors, we first conducted a sensitivity analysis. The results indicated that the radar reflectivity was highly sensitive to the particle size distribution (PSD) parameter of the median volume diameter and particle density parameter, which can cause reflectivity variations of several to more than 10 dB. The variation in the prefactor of the mass-power relations that related to riming degree may result in an uncertainty of approximately 30–45 %. The particle shape and orientation also had a significant impact on the radar reflectivity. The spherical assumption may result in an average overestimation of the reflectivity by approximately 4–8 %, dependent on the particle shape and orientation modeling. Typical weather cases were simulated using optimal physical modeling accounting for the particle shapes, typical PSD parameters corresponding to the cloud precipitation types, mass-power relations for snow and graupel, and melting modeling. We present and validate the simulation results for a cold front stratiform cloud and a deep convective process with observations from W-band cloud profiling radar (CPR) on the CloudSat satellite. The simulated brightness band features, echo structure, and intensity showed good agreement with the CloudSat observations; the average relative error in the vertical profile was within 20 %. Our results quantify the uncertainty in the millimeter wave radar echo simulation that may be caused by the physical model parameters and provide a scientific basis for optimal forward modeling. They also provide suggestions for prior physical parameter constraints for the retrieval of the microphysical properties of clouds and precipitation.

Abstract. We develop a phenomenological model of suspended-sediment transport on the basis of data acquired in the Capesterre river, which drains a small tropical catchment in Guadeloupe. The model correctly represents the transport of suspended sediment during floods, provided that the relation between concentration and water-level forms a counterclockwise loop. In the model, the properties of the sediment and of the river are all lumped into four parameters: a settling velocity related to the size of the suspended sediment, a threshold water-level which acts as a proxy for the threshold shear stress, a characteristic erosion rate and a dimensionless exponent, both of which are related to the availability of fine sediment. The assimilation of field data to our model shows that the value of the parameters change from one flood to the next, probably reflecting changes in the characteristics of the river and the sediment. Finally, a test of the model against data acquired in a small catchment in the french Alps, suggests that the model is versatile enough to be used in diverse hydrological settings.
The origin of hydrological responses following earthquakes in confined aquifer: Insight from water level, flow rate and temperature observations

Abstract. Although many mechanisms of earthquake-induced hydrological response have been proposed in recent decades, the origins of these responses remain enigmatic and a quantitative understanding of them is lacking. In this study, we quantitatively analyzed water level, flow rate, and water temperature data from an artesian well in southwestern China before and after multiple earthquakes. Water level and temperature always showed co-seismic step-like increases following earthquakes, which were independent of the earthquakes’ epicentral distances and magnitudes. Tidal analysis found changes in aquifer and aquitard permeability following these earthquakes, which correspond to the post-seismic discharge of 85~273 m3. Furthermore, we coupled the flow rate and temperature data to model the mixing processes that occurred following each earthquake. The results indicate that co-seismic temperature changes are the result of the mixing of different volumes of water from shallow and deep aquifers, with the mixing ratio varying according to each earthquake.

In the Senegal River watershed, land use is undergoing significant dynamics due to intense human activities that place the ecosystem in a precarious balance. The objective of this study is to quantify the landscape dynamics and explore the possible futures of land use using remote sensing, GIS and spatio-temporal modeling tools while coupling with climate change indicators. Socio-economic data and Modis-Terra images (2007, 2014 and 2019) were used. A multi-date classification was used to quantify land use changes. The Land Change Modeler (LCM) model was used to simulate and project land use in the Senegal River watershed up to 2030. The results show that between 2007 and 2019, there will be a significant regression of natural vegetation formations (water bodies, forests and wooded savannahs) and an increase in anthropogenic formations (mosaics of crops and fallow land) for the same period. The three Business-As-Usual (BAU), Rapid Economic Growth (REC) and Coordinated Environmental Sustainability (CES) scenarios, extrapolating current trends, show that by 2030 (the SDG horizon) this landscape will be dominated by crop and fallow land mosaics (+50%). Woody resources occupy 26% of the area in the DEC scenario, 23% in the BAU scenario and 19% in the CER scenario. The DEC scenario gives hope that restoration and preservation of plant resources is still possible if decision makers are aware of it.
Estimation of expected annual damage, EAD
Authors: Rosbjerg Dan
Published: September 2022

As an alternative to straightforward numerical integration of annual damage costs as function of either the return period or the exceedance probability, the expected annual damage, EAD, can be estimated analytically by using a log-linear model for the damage curve. With this model, it is found that it is important to assess the return period where damage begins as precisely as possible, and that the relative error in damage data gives rise to an error in EAD of the same order of magnitude. Moreover, the model allows for extrapolation above the largest return period for known damage costs. The precision of the EAD estimation is analysed in detail, and it is found that usual numerical integration over either the return period or the exceedance probability can give contradictory results, when only few data is available for the damage function. Using a piecewise log-linear damage function is show to be less sensitive to limited data availability. Finally, the necessary corrections when damage occurs below the 1-year return period are determined.

Spatial altimetry allows to complete in-situ hydrometric data through the establishment of "virtual stations", at the crossing of the satellite ground track with a watercourse. Elevation measurements of water bodies and rivers are available on the Hydroweb-NG website (http://hydroweb.theia-land.fr). The SWOT satellite, scheduled for launch mid november 2022 by the French Centre National d'Etudes Spatiales (CNES) and the U.S. National Aeronautics and Space Administration (NASA), should further improve accuracy, thanks to innovative technology. Other types of multi-sensor space data are also useful in hydrology. A project to support the International Commission of the Congo-Ubangi-Sangha river basin (CICOS) developed since 2016 with funding from the French Development Agency (AFD) has promoted space hydrology through a group of French institutions supporting CICOS. Various activities have been developed including the development of a spatial database, comparison with in-situ data and the development of an operational Hydrological Information System within CICOS, integrating both spatial and in-situ data.
In the framework of the Space Hydrology Group and the CICOS support project, an innovative methodology has been developed to estimate flows from currently available satellite data (Envisat, Jason, Sentinel, etc.), transforming altitudes into flows at virtual stations. These satellite data can be complemented by global databases (width databases with GWD-LR or Sword, mean flow databases with WBM, or Digital Terrain Model databases with SRTM Mission), as well as in-situ data on the studied area (2 hydrological stations in Kinshasa East on the Congo and Bangui on the Ubangi river). This methodology, tested on these 2 rivers, allowed the generation of a hydraulic model of the Saint-Venant 1D type, allowing the generation of Q(Z) calibration curves at any point of the river. Powered by satellite altimetry data, these calibration curves provide flow rates. A web-based interface has been developed providing this information in real-time. The comparision of the bathymetry obtained with this method with ADCP measurements, the analysis of the rating curve at two in-situ stations, and the time delay of the hydraulic model, proved to be very satisfactory, having into consideration all the hypothesis made in this methodology.

This study aims to investigate drought and flooding area in West Africa during the pre-industrial and projected future periods. The datasets used consist of CHIRPS-2 and CRU for observed reanalysis and CORDEX/CMIP6 for climate model scenarios. The CORDEX/ CMIP6’s potential evapotranspiration (PET) and precipitation correlate well with observation dataset over the study area with respective KGE up to 0.75 and 0.9. The pre-industrial period used in this research covers 1971-2000, while the projection period is defined according to the global warming level and the RCPs. Results showed that, the spatial and temporal repartition of SPEIs was elucidated by applying the Empirical Orthogonal Function (EOF) analysis, which showed that during the pre-industrial period, the wettest areas were located at the eastern and southern part of West Africa. The analyses on projected scenarios reveals that most of the coastal countries in Gulf of Guinea will be globally wetter under all the GWLs studied, with some interleaving as coastal countries (Senegal, Ivory-Coast, Benin, Togo and Nigeria). Some years will experiment extreme drought, whilst Savanna will get positive changes, which will lead them to become less dry compare to period 1971-2000. An investigation on the spatial concentration of precipitation using precipitation concentration index (PCI), have involved this study to highline an uniform spatial distribution of annual and wet season precipitations over gulf of Guinea and Savanna, follow by an increasing of uniform and moderate spatial distribution of precipitation under RCP4.5, and negative changes over eastern and western part of the study area for projection RCP8.5, explaining the high variability of concentration of precipitation over these regions.
