Abstract. Tipping elements, including the Antarctic Ice Sheet (AIS), are Earth system components that could reach critical thresholds due to anthropogenic emissions. Increasing our understanding of past warm climates can help to elucidate the future contribution of the AIS to emissions. The mid-Pliocene Warm Period (mPWP; ∼ 3.3–3.0 million years ago) serves as an ideal benchmark experiment. During this period, CO2 levels were similar to the present day (PD; 350–450 ppmv), but global mean temperatures were 2.5–4.0 K higher. Sea level reconstructions from that time indicate a rise of 5–25 m compared to the present, highlighting the potential crossing of tipping points in Antarctica. In order to achieve a sea level contribution far beyond 10 m, not only the West Antarctic Ice Sheet (WAIS) needs to largely decrease, but a significant response in the East Antarctic Ice Sheet (EAIS) is also required. A key question in reconstructions and simulations is therefore which of the AIS basins retreated during the mPWP. In this study, we investigate how the AIS responds to climatic and bedrock conditions during the mPWP. To this end, we use the Pliocene Model Intercomparison Project, Phase 2 (PlioMIP2), general circulation model ensemble to force a higher-order ice sheet model. Our simulations reveal that the WAIS experiences collapse with a 0.5 K oceanic warming. The Wilkes Basin shows retreat at 3 K oceanic warming, although higher precipitation rates could mitigate such a retreat. Totten Glacier shows slight signs of retreats only under high-oceanic warming conditions (greater than 4 K oceanic anomaly). If only the WAIS collapses, we simulate a mean contribution of 2.7 to 7.0 ms.l.e. (metres of sea level equivalent). If, in addition, the Wilkes Basin retreats, our simulations suggest a mean contribution of 6.0 to 8.9 ms.l.e. Besides uncertainties related to the climate forcing, we also examine other sources of uncertainty related to initial ice thickness and ice dynamics. We find that the climatologies yield a higher uncertainty than the dynamical configuration if parameters are constrained with PD observations and that starting from Pliocene reconstructions leads to smaller ice sheet configurations due to the hysteresis behaviour of marine bedrocks. Ultimately, our study concludes that marine ice cliff instability is not a prerequisite for the retreat of the Wilkes Basin. Instead, a significant rise in oceanic temperatures can initiate such a retreat.

Abstract. Marine heatwaves (MHWs) have been increasing in frequency, intensity, and duration worldwide, which poses a serious threat to marine ecosystems and fisheries. The Red Sea (RS), a semi-enclosed marginal sea, is highly vulnerable to climate change due to its small volume and slow rate of water renewal. Despite the importance of the RS, MHWs in this region remain poorly studied, and understanding of their spatial and temporal characteristics and forcing mechanisms is limited. This study examines MHWs in the RS over the last 4 decades (1982–2021) and their relationship to large-scale climate modes, with particular focus on the 2010 MHW event in the northern Red Sea (NRS). Analysis of sea surface temperature anomaly (SSTA) trends in the RS revealed a decadal variability, with the highest warming trends occurring alternately in the northern and southern regions. The RS has experienced a significant warming trend over the last 4 decades, which has intensified since 2016. This warming has led to an increase in the frequency and duration of MHWs in the region, with 46 % of events and 58 % of MHW days occurring only in the last decade. The RS exhibits a meridional gradient, with decreasing mean annual MHW intensity and duration but increasing mean annual MHW frequency from north to south. The annual MHW frequency in the NRS peaked in 2010, 2018, 2019, and 2021, while, in the Southern Red Sea (SRS), the highest frequency occurred in 1998 and from 2017 to 2021. The study also examined the correlation between MHWs and climate indices and found that the Atlantic Multidecadal Oscillation (AMO), the Indian Ocean Dipole (IOD), and the East Atlantic/West Russia pattern (EATL/WRUS) were the three dominant modes that correlated with SSTAs and MHWs in the region. The North Atlantic Oscillation (NAO) and the Oceanic Niño Index (ONI) showed weaker and less significant correlations. Finally, the authors conducted a case study of the 2010 MHW event in the NRS, which was the most intense and longest winter event of the year. Using a high-resolution ocean model and atmospheric reanalysis data, it was found that the MHW in late winter 2010 in the NRS extended to a depth of 120 m and was driven by a combination of atmospheric forcings, particularly an increase in air temperature (Tair) and humidity, possibly linked to reduced winds leading to reduced latent heat flux (LHF) and strong ocean warming, creating favourable conditions for MHWs to occur.

This research is motivated by the obsevations of researchers who found that learning conducted by teachers only uses the lecture method, so that students tend to only listen to what is conveyed by the teacher which results in no feedback which causes students to be less active in learning Fiqih. The purpose of this study was to find out how much influence the application of the debate method had on learning activities in class X Fiqih subjects at MAS Muhammadiyah Lawag Tigo Balai. The type of research used in this study is a quantitative approach, using a Quasy Experimental research design with The Non-equivalent Group Design. The students to be sampled were class X IPK as the experimental class and class X IPS as the control class. The students to be sampled were class X IPK as the sampling technique was to collect data on students’ daily scores, after which a normality test and homogeneity test were carried out. After confirming that they were normal and homogeneous, the researcher determined randomly for the experimental class and the control class. In this study the instrument of student learning activities will be used. Based on the research results obtained tcount = 11,114 ˃ 2,024 and sig. (2-tailed) 0,00 ˂ 0,005. Then the hypothesis is accepted which states that there is a significant influence between the debate method and conventional lerning methods, it means that Ho is rejected. So it can be concluded that there is a significant influence of the debate method on learning activities in class X Fiqih subjects at MAS Muhammadiyah Lawang Tigo Balai.

El desarrollo tecnológico ha permitido cambios significativos en la vida cotidiana, desde la invención de la rueda hasta la creación de dispositivos móviles personales, impactando día a día el entorno social en todos los niveles. Uno de los avances más significativos indudablemente es el internet, herramienta que cambio el estilo de vida de la humanidad. El trabajo de investigación se elaboró utilizando el enfoque cuantitativo, con el tipo de investigación descriptivo, se aplicó el método bibliográfico y estadístico. Se pudo determinar la fiabilidad del cuestionario a través del coeficiente Alfa de Cronbach con el resultado de 0,962 sobre 1. Se utilizó la técnica de investigación de la encuesta. Identificando una población de 26.872 clientes que cuentan con internet plan hogar de sus viviendas de los cuales el 61% corresponde ENTEL S.A., el 27% a TIGO y el 12% a COTES LTDA. Se realizo 379 encuestas. El muestreo utilizado fue probabilístico, con la técnica de muestreo estratificada desproporcionada.Para identificar el nivel de satisfacción de los clientes de las empresas Entel S.A., Tigo y Cotes Ltda. que cuentan con el plan internet hogar en el área urbana de la ciudad de Sucre, se procedió a utilizar el modelo Servqual, que define un servicio de calidad como la diferencia entre las expectativas versus las percepciones de los clientes mediante cinco dimensiones: Fiabilidad, Capacidad de respuesta, Confianza, Empatía y Elementos tangibles, que pueden ser evaluadas mediante el modelo de cuestionario en escala de Licker.Considerando lo mencionado anteriormente se identificaron 26 ítems repartidos en consultas dentro de las cinco dimensiones. En cuanto a los resultados obtenidos se validaron que: Los clientes del plan de Internet hogar no esperan demasiado sobre el servicio de estas empresas ya que ninguna empresa llega a obtener un 4 como calificación y mucho menos se acerca a 5, esto debido a varios aspectos siendo uno la baja velocidad del internet. También se pudo identificar que los clientes, adquieren el servicio porque se convirtió de vital importancia por el contexto actual de la pandemia, aunque las expectativas no son tan altas. Finalmente, en el cálculo de las brechas Entel S.A. y Cotes Ltda. presentan un similar puntaje de -0,44 y -0,43, reflejando que ninguna de las empresas satisface mediante a los clientes. Tigo es la única empresa que alcanzo una brecha media total de -0,09, por lo tanto, sus clientes se encuentran cercanos a estar satisfechos y por último la única dimensión (Empatía), en esta investigación superó las expectativas de los clientes reflejando una fortaleza para a empresa Tigo.

Rapid advancements in digital technology have changed a number of sectors in recent years. Artificial intelligence (AI) and robotics are two examples of advanced technology that have been adopted into the medical industry. The intraoral scanner is a portable device with a tiny optical camera that collects virtual dental models that is widely employed in dentistry that works by projecting structured light (white, red, or blue). The program then compiles the individual photos or video that are captured after identifying certain locations of interest. The points of interest captured from various perspectives are then matched to create a 3D model. One of the biggest benefits of intraoral scanning is that it eliminates all the painful parts of taking a traditional impression and allows for the simple rescanning of certain areas that may not have been recorded completely. Hence, this review article will be discussed on principles of imaging, different brands of IOS, advantages and advancements in IOS.
