Authors: Pretelt (•2016) Felipe , Rivera Neiby , Ursida Valentina , Ramírez Ayelet
Published: February 2024

La enfermedad de Creutzfeld-Jakob es una patología neurodegenerativa fatal e intratable, que hace parte de las denominadas encefalopatías espongiformes y se produce por la acumulación anormal de la PrP (proteína priónica patogénica),denominada PrPsc, a nivel del sistema nervioso central. La enfermedad priónica humana más común es la forma esporádica de la enfermedad de Creutzfeld-Jakob, cuya aparición se ha relacionado con los efectos ambientales desconocidos o los sucesos aleatorios y genéticos, que resultan en la producción espontánea de PrP en el cerebro.

A continuación se presentan dos casos clínicos de dos mujeres que consultan al servicio de urgencias del Hospital Universitario San Ignacio, en quienes se sospechó encefalopatía rápidamente progresiva, compatible con enfermedad de Creutzfeld-Jakob.

Published: February 2024

La infiltración de anestésico local (AL) está cada vez más extendida como indicación en el tratamiento del dolor neuropático. La intoxicación por AL es poco frecuente pero grave, potencialmente mortal y de difícil manejo. Cursa con afectación del nivel de conciencia, crisis comiciales y bloqueos de la conducción cardiaca. La emulsión lipídica (EL) al 20 % es el único tratamiento específico descrito hasta la fecha y ha mejorado el pronóstico de estos casos. Presentamos el caso de un paciente con deterioro neurológico progresivo tras la infiltración de altas dosis de AL por un dolor neuropático refractario a otros tratamientos. El paciente fue tratado con emulsión lipídica al 20 % revirtiendo el cuadro neurológico de forma precoz y completa. La aparición de síntomas neurológicos progresivos en el contexto de una infiltración de anestésico local debe alertarnos sobre una posible intoxicación para iniciar tratamiento precoz con emulsión lipídica al 20 %, evitando un pronóstico infausto. Sin embargo, la prevención sigue siendo la herramienta principal.

Published: February 2024

La hiperplasia suprarrenal congénita (HSC) es un trastorno genético que produce déficit en la síntesis del cortisol. Esta enfermedad se presenta en ambos géneros, puede ser diagnosticada prenatalmente y recibir tratamiento desde esta etapa. A nivel fisiológico presenta ambigüedad en los órganos sexuales internos y externos que afectan el desarrollo emocional y social. En el nivel cognitivo se pueden encontrar dos posturas una donde se afirma que en pacientes con HSC se presentan puntuaciones bajas en el Coeficiente Intelectual (CI), especialmente en el (CI)verbal y diferencias significativas en pacientes que no han recibido tratamiento a tiempo, la otra considera que esta enfermedad no afecta los procesos cognitivos. En el presente artículo se realiza un estudio de caso único de un adolescente de 13 años con HSC, con el objetivo de describir el perfil cognitivo de un adolescente con hiperplasia suprarrenal congénita y compararlo con los estudios existentes en la actual literatura. Se obtuvo un perfil cognitivo por medio de diferentes pruebas neuropsicológicas, encontrando en el paciente un retardo mental moderado CI 50 y alteraciones importantes del lenguaje y del aprendizaje.
Exploring junior high school students' geometry self-efficacy in solving 3D geometry problems through 5E instructional model intervention: A grounded theory study
Authors: Sudirman Sudirman , García-García Javier , Rodríguez-Nieto Camilo Andrés , Son Aloisius Loka
Published: February 2024

Geometry self-efficacy is an essential affective aspect that will influence students in solving mathematics problems, especially geometry material. Therefore, teachers must be able to develop learning instructions that not only affect students' mathematical abilities but also strengthen students' affective aspects. This research explores students' geometry self-efficacy when learning to solve three-dimensional geometry problems through the 5E Instructional Model intervention. A grounded theory design was used to reveal the aims of this research. Participants in this research were one mathematics teacher and 22 students (12 girls and 10 boys) in class VIII at a state Junior High School in Indramayu Regency, Indonesia. The research involved the qualitative analysis of gathered data obtained through observation, questionnaires, interviews, and documentation, employing grounded theory analysis techniques, including open coding, axial coding, and selective coding. The findings revealed that students with high self-efficacy in geometry display confidence in describing and calculating the surface area and volume of three-dimensional geometric objects. Those with moderate self-efficacy in geometry are self-assured in addressing straightforward assignments but may need more confidence in tackling more complex tasks. Conversely, students with low self-efficacy in geometry tend to need more confidence and are prone to giving up easily. Therefore, this research emphasizes that the geometry self-efficacy level can influence how students act and complete 3D geometry tasks given by teachers in learning, especially 3D geometry learning.
The Role of Acantharia in Southern Ocean Strontium Cycling and Carbon Export: Insights from Dissolved Strontium Concentrations and Seasonal Flux Patterns
Authors: Sun Yaojia , Wynn-Edwards Cathryn , Trull Thomas W. , Ellwood Michael J
Published: February 2024

Dissolved strontium (Sr) concentrations in the Southern Ocean water
samples and Sr export fluxes from sediment trap moorings at 1000 m were
used to assess particulate organic carbon (POC) export associated with
Acantharia for 2010, 2018 and 2020. The dissolved Sr data revealed a
prominent vertical gradient with lower surface Sr concentrations
depleted up to 1.4% relative to deep waters. A strong latitudinal
surface gradient was observed, ranging from 87.3 near the northern end
to 88.5 near the southern end of a transect through the Australian
sector of the Southern Ocean. These findings highlight the significant
role that Acantharia, which precipitate celestite (SrSO4), play in
marine Sr cycling. Seasonal variability in Sr export fluxes can be
large, particularly during intense events in summer, and reaches a
maximum of 2.8 , contributing up to 7% of the POC export flux. The
coincidence of Sr flux with the second peak of POC export flux implies a
potential association of Acantharia biomass with summertime
productivity.
Shear-driven vertical mixing and turbulent exchange over the continental slope in the northwestern Sea of Japan
Authors: Stepanov Dmitry , Ostrovskii Alexander , Ryzhov Evgeny , Lazaryuk Alexander
Published: February 2024

Using fine-scale measurements in the northwestern Sea of Japan, we estimated the vertical mixing parameters in the sea water column extended from the lower part of the thermocline downward to the near-bottom layer above the continental slope. The vertical scales of the turbulent patches were determined together with the turbulent dissipation rate and diapycnal diffusivity based on the conductivity, temperature, and depth data obtained by an Aqualog moored profiler from April through October 2015. The Thorpe-scale method was used to estimate the vertical mixing parameters as well as the vertical heat and salt fluxes. The enhanced vertical mixing, as well as enhanced upward heat flux and downward salt flux, occurred below the mixed layer despite strong density stratification. By comparing the turbulent dissipation rate and diapycnal diffusivity estimates derived via the Thorpescale method and the estimates of the same parameters obtained earlier by applying the finescale parameterization method to the same dataset in addition to the collocates of the current velocity measurements, the comparative accuracy evaluation of both methods was carried out. Finally, by compiling the vertical mixing data obtained by the Thorpe-scale method and the finescale parameterization approach, the generalized depth profile for the background diapycnal diffusivity is presented for the depth range from 70 to 350 m.

Authors: Saeibehrouzi Ali , Abolfathi Soroush , Denissenko Petr , Holtzman Ran
Published: February 2024

Solute transport in partially-saturated porous media plays a key role in multiple applications across scales, from the migration of nutrients and contaminants in soils to geological energy storage and recovery. Our understanding of transport in unsaturated porous media remains limited compared to the well-studied saturated case. The focus of this review is the non-reactive transport driven by the displacement of immiscible fluids, where the fluid-fluid interface acts as a barrier that limits the solute to a single fluid phase. State-of-the-art pore-scale models are described, with a critical analysis of the gaps and challenges. A numerical example is provided to demonstrate the acute sensitivity of solute transport prediction to minute, inevitable uncertainties in the spatial distribution of the fluids’ velocities and interface configuration associated with the multiphase flow modeling.
Impact of Politeness and Performance Quality of Robots on Future Interaction Decisions: A Conversational Design Perspective
Authors: Saeki Waka , Ueda Yoshiyuki
Published: February 2024

Despite robots being applied in various situations of modern society, some people avoid them or do not feel comfortable interacting with them. Designs that allow robots to interact appropriately with people will make a positive impression on them resulting in a better evaluation of robots, which will solve this problem. To establish such a design, this study conducted two scenario-based experiments focusing on the politeness of the robot’s conversation and behavior, and examined the impressions caused when the robot succeeds or slightly fails at a task. These two experiments revealed that regardless of whether the partner is a robot or a human, politeness not only affected the impression of interaction but also the expectations for better task results on the next occasion. Although the effect of politeness on preference toward robot agents was smaller than those toward human agents when agents failed a task, people were more likely to interact with polite robots and human agents again because they thought that they would not fail the next time. This study revealed that politeness motivates people to interact with robots repeatedly even if they make minor mistakes, suggesting that the politeness design is important for encouraging human-robot interaction.
Microseismic Monitoring using Transfer Learning: Example from the Newberry EGS
Authors: Leong Zi Xian , Zhu Tieyuan
Published: February 2024

Enhanced geothermal systems (EGS) are promising for generating clean
power by extracting heat energy from injection and extraction of water
in geothermal reservoirs. The stimulation process involves hydroshearing
which reactivates pre-existing cracks for creating permeability and
meanwhile inducing microearthquakes. Locating these microearthquakes
provide reliable feedback on the stimulation progress, but it poses a
challenging nonlinear inverse problem. Current deep learning methods for
locating earthquakes require extensive datasets for training, which is
problematic as detected microearthquakes are often limited. To address
the scarcity of training data, we propose a transfer learning workflow
using probabilistic multilayer perceptron (PMLP) which predicts
microearthquake locations from cross-correlation time lags in waveforms.
Utilizing a 3D velocity model of Newberry site derived from ambient
noise interferometry, we generate numerous synthetic microearthquakes
and 3D acoustic waveforms for PMLP training. Accurate synthetic tests
prompt us to apply the trained network to the 2012 and 2014 stimulation
field waveforms. Predictions on the 2012 stimulation dataset show major
microseismic activity at depths of 0.5–1.2 km, correlating with a known
casing leakage scenario. In the 2014 dataset, the majority of
predictions concentrate at 2.0–2.9 km depths, consistent with results
obtained from conventional physics-based inversion, and align with the
presence of natural fractures from 2.0–2.7 km. We validate our findings
by comparing the synthetic and field picks, demonstrating a satisfactory
match for the first arrivals. By combining the benefits of quick
inference speeds and accurate location predictions, we demonstrate the
feasibility of using transfer learning to locate microseismicity for EGS
monitoring.
Impact of buffering time reduction on false congestion detection in TCP vegas over OBS networks
Authors: Le Van
Published: February 2024

Since Transmission Control Protocol (TCP) is the dominant protocol on the
Internet and optical burst switching (OBS) networks represent the optical
transmission solution that can meet future high bandwidth requirements, TCP
and OBS networks represent a possible combination for the next-generation
Internet. However, a problem with this combination model is that operations
at the OBS layer need to be controlled so that false congestion detection at
the TCP layer is minimised. Considering the combination of TCP Vegas and
OBS, congestion detection at the TCP layer is based on the round-trip time
(RTT), where congestion is detected if the current RTT exceeds a given
RTTmax. The extra delay may be due to some actual loss, but it may also be
due to the extended execution time caused by some OBS layer operations.
Therefore, reducing the time of operations at the OBS layer will reduce
false congestion detection at the TCP layer. This paper investigates the
impact of reducing the buffering time at the ingress node on the false
congestion detection rate at the TCP layer. The reduction of the burst
buffering time is accomplished by nesting the offset time in the assembly
time. The simulation results and analysis show that the transmission
efficiency in TCP Vegas over OBS networks is significantly improved; the
throughput remains high, and the delivery success rate is significantly
increased compared to the conventional buffering mode.
Reklame utnytter samfunnsdebatten. En studie av strategisk kommunikasjon i reklamefilm for intimsåpen Asan
Authors: Nilsen Anders , Pro-Rector Jens Barland , Sandstad Bård Blytt
Published: February 2024

Strategic communication promoted by advertising wrapped as political debate. This is the topic explored in this study, which deals with an advertising campaign for the intimate soap Asan. With a commercial film, Asan’s owner promotes a social debate about whether all the porn on the internet destroys natural erotic intimacy of young people. By theories on strategic communication, marketing and visual storytelling, it is analyzed how such an advertising campaign is developed in accordance with recognized means of influence. The theme appears as appropriate and well-placed moral debate in society but is an advanced form of advertising and marketing. The content in the commercial film is tailored to provoke and to be spread further over several media channels. Censorship and conflicts provide opportunities for debate and increased attention both in social media and in editor-controlled media. The study analyses both the strategic level for creating and maintaining the public debate and the more tactical and operative means used in visual storytelling. An international trend in marketing is brands’ efforts to be associated with political positions, and the case with Asan demonstrates such a practice in a Norwegian context.

Authors: Maramba Aaron
Published: February 2024

Background: Anaemia is a common complication of HIV infection that can have a significant impact on the health and wellbeing of affected individuals. Evaluating the relationship between haemoglobin concentration, CD4 count and viral load is therefore important in order to predict and reduce the risk of anaemia in people living with HIV. Objectives: The aim of this study was to evaluate the relationship between haemoglobin concentration, CD4 count and viral load in people living with HIV. Method: This retrospective cross-sectional study was carried out at Parirenyatwa Opportunistic Infections Clinic, Zimbabwe. The study was conducted from November 2022 to April 2023. The data collected from each patient`s data base included; demographics, haemoglobin value, CD4 count and viral load count. Data collected during this study were captured on spreadsheet using Microsoft excel and the data were analyzed using the Graph Pad prism software. Results: A total of 244 participants were enrolled into the study from the Parirenyatwa Group of Hospitals Opportunistic Infections Clinic of which 102 (41.8%) were male and 142 (58.2%) were female. Participants with high CD4 count and low viral load had a mean haemoglobin of 13.3g/dL, those with low CD4 count and high viral load count had a mean haemoglobin of 8.3g/dl, those with high CD4 count and high viral load count had a mean haemoglobin of 12.5g/dl and those with low CD4 and low viral load count had a mean haemoglobin of 10.70g/dl. Conclusion: The overall finding from this study was that haemoglobin levels of people living with HIV is greatly affected by viral load and CD4 counts and that patients’ haemoglobin levels inversely tract the HIV viral loads. Low CD4 count and/ or high viral load count is associated with anaemia in people living with HIV.

Authors: Apriatni Sri , Nindiasari Hepsi , Sukirwan Sukirwan , Khaeroni Khaeroni
Published: February 2024

Background: In today's ever-changing landscape, students need strong numerical literacy skills to navigate life's complexities. Recognizing that students come with various learning capabilities, often referred to as "instructional levels," educators must think outside the box when it comes to teaching methods.Aim: This study aims to 1) gauge whether creative problem solving (CPS) or scientific learning is more effective in enhancing the numerical literacy skills of MA students; 2) assess the difference in the numerical literacy progress among MA students categorized at independent, instructional, and frustration levels; and 3) explore the interplay between teaching methods and instructional levels on students’ numerical literacy development.Method: Conducted as an experimental study, this research employs a 3x2 factorial design. Participants include students from Class X IPA at MAN 2 Serang. To collect data, we used tests focused on numerical literacy as well as assessments to categorize instructional levels. A two-way ANOVA serves as the statistical approach to test our hypotheses.Result: 1) MA students exposed to the CPS method showed greater improvements in their numerical literacy skills than those who engaged in scientific learning; 2) A noticeable variance exists in the growth of numerical literacy skills among MA students at independent, instructional, and frustration levels; 3) An interaction effect was identified between the chosen teaching method and the instructional level in shaping the numerical literacy skills of MA students.Conclusion: The study concludes that creative problem-solving is more potent than scientific learning in elevating the numerical literacy of MA students. Furthermore, instructional levels play a crucial role in this improvement. A synergistic effect between the teaching approach and instructional level was also found to influence the numerical literacy outcomes.
Metacognition patterns of the students in solving mathematical problems: Analyzed from adversity quotient and gender
Authors: Widiyasari Ririn
Published: February 2024

Background: Metacognition significantly influences students' effectiveness in solving mathematical problems. Variability in metacognitive patterns among students is shaped by factors such as adversity quotient (AQ) and gender.Aim: This research aimed to explore metacognitive patterns in mathematical problem-solving among students majoring in mathematics at Universitas Muhammadiyah Jakarta, with a specific focus on differences due to AQ and gender.Method: Adopting a qualitative approach with a phenomenological framework, this study included six students (three males and three females) from the 2021–2022 academic year. These students represented different AQ categories: climber, camper, and quitter. Data collection involved tests, observations, and interviews.Results: The investigation showed that students with a climber AQ, irrespective of gender, adeptly utilized all metacognitive knowledge facets: declarative, procedural, and conditional. In contrast, male campers engaged primarily in declarative and procedural knowledge, while male quitters demonstrated negligible engagement. Female campers predominantly employed declarative knowledge, occasionally integrating conditional knowledge. Female quitters, however, did not exhibit significant usage of metacognitive knowledge. Regarding metacognitive regulation—planning, monitoring, and evaluation—students identified as climbers displayed proficiency across all these aspects, regardless of their gender.Conclusion: The study underscores the influence of AQ and gender on metacognitive patterns in mathematical problem-solving, noting an exception in climbers who consistently exhibit effective metacognition. These insights could guide educational strategies to bolster metacognitive skills in the context of mathematics education.

Sagu merupakan salah satu sumber bahan makanan bagi masyarakat di Tana Luwu. Pengolahan pati sagu menghasilkan limbah cair dan limbah padat yang jika tidak ditangani dengan baik dapat menyebabkan pencemaran lingkungan. Ampas sagu dan pucuk batang sagu adalah limbah padat yang dihasilkan dari pengolahan pati sagu yang masih mengandung selulosa cukup tinggi. Kandungan selulosa yang tinggi merupakan potensi yang besar untuk dapat diolah dan dimanfaatkan kembali sehingga dapat mengurangi jumlah limbah yang dibuang ke lingkungan. Penelitian ini bertujuan untuk memanfaatkan potensi ampas sagu sebagai media pertumbuhan ulat sagu berdasarkan berat dan panjang ulat sagu. Penelitian ini merupakan penelitian eksperimen dengan menggunakan metode Rancangan Acak Lengkap (RAL) dengan perlakuan penambahan ampas sagu sebanyak 25 gram (P1), 30 gram (P2), 35 gram (P3), dan 40 gram (P4) dengan pengamatan selama 20 hari. Data yang diperoleh dianalisis dengan metode Regresi Linear. Hasil penelitian menunjukkan bahwa pemberian ampas sagu berpengaruh signifikan terhadap perkembangan berat ulat sagu (Sig. 0,007 < 0,05) dan panjang ulat sagu (Sig. 0,009 < 0,05).

Metode yang digunakan pada praktikum ini ialah metode kuantitatif dengan melakukan percobaan atau eksperimen dengan virtual lab Phet Simulation. Hasil yang didapatkan dari praktikum ini, pengaruh tegangan terhadap kuat arus, kuat arus akan semakin besar saat tegangan dinaikkan yang artinya hubungan keduanya berbanding lurus. Sedangkan pengaruh hambatan, semakin besar hambatan yang diberikan maka kuat arus yang dihasilkan akan semakin kecil. Artinya hubungan hambatan dengan kuat arus berbanding terbalik.
Contingency versus inevitability: a review and reinterpretation of Stephen Jay Gould’s book “Wonderful Life—The Burgess Shale and the Nature of History”
Authors: Espesset David L.
Published: February 2024

In 1989, Stephen Jay Gould published his Wonderful Life: “High in the Canadian Rockies is a small limestone quarry formed 530 million years ago called the Burgess Shale. It holds the remains of an ancient sea where dozens of strange creatures lived a forgotten corner of evolution preserved in awesome detail. In this book Stephen Jay Gould explores what the Burgess Shale tells us about evolution and the nature of history”. Gould, based upon a reinterpretation of the famous fossils from the Burgess Shale, proposed a conclusion that was revolutionary at the time, because it was centred on the notion of contingency in the course of biological evolution. The very last paragraph displayed in particular the following sentences: “This response does not cite a single law of nature; it embodies no statement about predictable evolutionary pathways, no calculation of probabilities based on general rules of anatomy or ecology. I do not think that any ‘higher’ answer can be given, and I cannot imagine that any resolution could be more fascinating.” In this essay, I intend to criticise Gould’s conclusions and to provide a new reinterpretation of the history of life, based not on contingency but on the inevitability of evolution.
