La semana trágica en Barcelona en 1909 y un cuento sobre dos masones
Authors: Hottinger Craig Sylvia 
Published: February 2025

A través de una revisión de las fuentes de la Semana Trágica en Barcelona y el estudio de las fotografías de los eventos de 1909 vemos como el Imperio español no solamente persiguió a las personas que colonizó sino también a la gente de su propio pueblo. Igualmente, es la historia de los dos masones acusados de organizar la rebelión. Algunas de estas imágenes se confunden con las fotografías hechas durante la Guerra Civil Española en Barcelona (1936-1939).
Intra-sinus decontamination for maxillary sinus infection related to the apically exposed implant in the sinus: A report of two cases
Authors: Park Won-Bae , Buranawat Borvornwut , Shin Seung-Il , Lim Hyun-Chang 
Published: February 2025

Abstract
The apically exposed implant in the maxillary sinus may contribute to sinus inflammation during the early healing phase or afterward. The exposed surface of the implant can act as a reservoir for infectious agents. This case report presents two cases where an intraoral approach was used to manage maxillary sinus infections related to exposed implants within the sinus. In both cases, bony access windows were created on the lateral wall of the sinus to reach the apically exposed portion of the implant. In case 1, mechanical (titanium curettes and a rotating titanium brush) and chemical decontamination (tetracycline HCl solution-soaked cotton pellets) were performed. In contrast, case 2 involved chemical decontamination performed only after removing inflammatory tissues and fluids. Following treatment, the patients' sino-nasal symptoms completely resolved. Radiographic evaluations showed a significant reduction in mucosal thickening and bone formation around the exposed portion of the implant. Intra-sinus decontamination may be a viable option for treating infected maxillary sinuses related to apically exposed implants. The current protocol should be verified in more cases with longer-term follow-up.

Abstract
While it is widely accepted that the steel-concrete interface (SCI) plays an important role in governing the long-term durability of reinforced concrete structures, the understanding about the primary features of the SCI that influence corrosion degradation mechanisms has remained elusive. This lack of knowledge can be attributed to, firstly, the complex heterogeneous nature of the SCI, and secondly, the absence of established experimental techniques suitable for studying the relevant SCI features. Here, we use focused ion beam—scanning electron microscopy (FIB-SEM) nanotomography to obtain high-resolution 3D tomograms of the SCI. Five tomograms, spanning volumes ranging from 8000 to

, of both non-corroded and corroded SCIs were acquired. The achieved voxel size falls within the range of 30–50 nm, which captures capillary pores highly relevant for moisture and ion transport. Potential pitfalls when applying the FIB-SEM technique to the SCI are highlighted, including aspects related to the electron detectors. We present an image processing pipeline that reduces artifacts and generates tomograms segmented into solid matrix and pore space. Furthermore, to characterize the SCI pore structure, diffusion tortuosity and porosity profiles. The analysis showed that there is a pronounced anisotropy in the pore structure. This work demonstrates that the FIB-SEM technique can be applied to acquire high resolution tomograms of the SCI pore structure, which can be digitally analyzed to inform transport models of the SCI.

Published: February 2025

No presente ensaio, enfrentamos o problema do preconceito relacionado à educação à distância (EaD) no contexto brasileiro. Nosso objetivo consistiu em demonstrar de que modo tal preconceito pode ser desdobramento de um fenômeno mais amplo e complexo, cujas raízes encontram-se no racismo como mecanismo de reprodução e manutenção dos interesses da elite econômica. Partimos do pressuposto de que tal preconceito resulta da expansão do ensino superior brasileiro, em que a EaD ocupa papel central, justamente porque permite que camadas expressivas de uma parcela historicamente negligenciada – majoritariamente constituída por negros e pobres – possa acessar níveis superiores de formação. Avançamos demonstrando a necessidade de que, para que a EaD se consolide como um potente instrumento da democracia educacional, é crucial a existência de uma crítica permanente que possa, seguindo os pressupostos da teoria crítica da tecnologia, apontar para uma racionalidade democrática.

Background: Moringa oleifera has garnered significant interest. This research evaluated the impact of different quantities of Moringa oleifera seed powder on certain productive and physiological characteristics in Awassi ewes. The research investigated the effects on lamb development and birth outcomes within a sheep herd managed by Rashidiyah Research Station, Agricultural Research Service, Ninawa Research Department, Mosul, Iraq. Methods: Twenty ewes were divided into four groups of five ewes per group. Moringa seed powder was given to four groups: 0, 5, 10 and 15 (g/ewe/day). The weights of the newborns and mothers were recorded on the first day of the trial (0 days) and then the weights were taken at equal intervals of 15 days and on two consecutive days after the newborns were isolated from their mothers for 12 hours, these measurements continued the length of the trial. Blood tests were performed at the Physiology Laboratory of the Department of Animal Production Technologies at the Northern Technical University/Agricultural Technical College. cholesterol, triglycerides, glucose, urea, creatinine and liver enzymes including Aspartate alanine transferase (AST) and alanine aminotransferase (ALT). Result: Results of this study revealed that moringa seed powder supplementation (0, 5, 10, 15 g/head/day) significantly reduced feed intake for both ewes (2.087, 2.020, 1.769, 1.849 kg/ewe/day) and newborns (0.803, 0.770, 0.744, 0.758 kg/newborn/day). Ewes fed moringa also showed significant weight gains, with final weights reaching 59.6, 62, 58.6 and 57 kg across groups, compared to the control. Blood analysis showed an increase in leukocytes (20.23, 21.93, 20.97 and 16.03 ´ 10^9/L) and lymphocytes, while granulocyte ratios remained similar. Total cholesterol significantly decreased in the moringa-fed groups (120.66, 86.54, 92.12 and 82.72 mg/100 ml), though triglycerides stayed stable (47.2-49.08 mg/100 ml). Glucose levels dropped with higher moringa doses (45.87, 45.28, 49.1 and 33.3 mg/100 ml). Urea levels decreased (46.93, 40.36, 43.44 and 47.05 mg/100 ml), while AST levels were lower in specific groups. ALT levels showed minimal change, with values between 15 and 19.2 IU/L across groups.

The incorporation of artificial intelligence (AI) into the healthcare system has been revolutionized, promising keyadvancements in diagnosis, treatment, patient care, administrative tasks, and operational efficiency.The implementation of artificial intelligence into the healthcare system has been very transformational, productive, and hopeful, with the potential to revolutionize diagnosis, treatment, patient care, administrative work, and operational efficiency. Using an in-depth analysis of the extensive amount of literature on artificial intelligence and how it could help the medical industry, this study identified the eleven barriers and challenges. An interpretative structural modelling (ISM) has been used as a methodological approach to find out the relationship between the extracted challenges and their dependency and driving powers. It resulted in a five-tiered model with introduction of innovative and new generation tools topping the chart as the most dependent challenge. Similarly Insufficient Data, Data Acquisition, Data Misuse and Missing Compassion being the key drivers.

Authors: Sanders Philip , Scheper Henk , van der Wal Robert , van de Sande Michiel , de Boer Mark , Sander Dijkstra Pieter Durk , Bus Michael 
Published: February 2025

Background:
Periprosthetic joint infection (PJI) surrounding an endoprosthesis after reconstruction of a lower extremity following tumor resection is a common complication, and the treatment of these infections is challenging and often requires multiple surgical interventions or even implant removal. Because there has been limited evidence to support treatment strategies and understanding of the epidemiology of the causative microorganisms, we analyzed the effectiveness of debridement, antibiotics, and implant retention (DAIR), risk factors for the failure of DAIR, and causative microorganisms in patients with a PJI surrounding a lower-extremity endoprosthesis after tumor resection.

Methods:
A retrospective cohort study was conducted in a tertiary referral center for orthopaedic oncology. All patients treated between 2000 and 2018 for PJI surrounding a lower-extremity endoprosthesis after tumor resection were included. Treatment outcomes and risk factors for failure were analyzed in patients primarily treated with DAIR. Causative microorganisms were recorded. The minimum follow-up period was 2 years.

Results:
Of the 337 patients who underwent endoprosthetic reconstruction of a lower extremity after tumor resection, 67 patients (20%) developed a PJI surrounding the endoprosthesis. Of those patients, 55 were primarily treated with DAIR. The functional cure rate of DAIR was 65% (36 of 55). A median of 2 debridements per patient was needed. Chemotherapy (odds ratio [OR], 3.1 [95% confidence interval (CI), 1.0 to 9.3]) and an erythrocyte sedimentation rate of >50 mm/hr at diagnosis (OR, 4.5 [95% CI, 1.3 to 15.4]) were associated with treatment failure. Nineteen patients (28%) had a polymicrobial infection.

Conclusions:
Although sequential procedures are often needed, DAIR has acceptable clinical outcomes and should be considered, dependent on expected survival and the risk factors for treatment failure noted in this study.

Authors: Batailler Cécile , Lustig Sébastien , Balot Emmanuel , Farizon Frédéric , Fessy Michel Henri , Philippot Rémi 
Published: February 2025

Background:
Dual mobility cups (DMCs) have effectively prevented dislocations after total hip arthroplasty (THA). However, use of these cups in primary THAs remains controversial, especially in young patients. This study aimed to determine the long-term survival rate and functional outcomes of a contemporary DMC used in primary THA.

Methods:
This retrospective multicenter study identified a cohort of 614 primary THAs performed with the same uncemented monoblock DMC between 2007 and 2010. Survival analysis included 572 THAs, while clinical analysis involved 394 THAs at a minimal follow-up of 10 years. The mean follow-up was 11.1 ± 1.2 years. The mean age was 71.4 ± 11.7 years, with 4.2% of patients under 50 years old. The mean body mass index was 27.0 ± 5.3 kg/m2. The 10-year Kaplan-Meier survival rate was calculated based on cup removal for any reason or cup revision for an aseptic reason as the end point. Harris hip scores were collected at the last follow-up.

Results:
The cup-revision-free survival rate was 98.6% at 10 years and 96.2% at 13 years. No cup revisions were reported due to aseptic loosening or dislocation. The cup revisions were due to infection (7 of 572; 1.2%), acetabular fracture (1 of 572; 0.17%), and psoas impingement due to cup malpositioning (n = 1 of 572; 0.17%). Only 3 dislocations (0.52%) were observed, and they did not require revision. The mean Harris hip score significantly improved from 54.1 ± 14.4 preoperatively to 88.0 ± 14.3 at the last follow-up (p < 0.0001). For patients under 50 years old at the time of surgery, the mean Harris hip score showed significant improvement from 53.0 ± 10.2 preoperatively to 89.7 ± 12.8 at the last follow-up (p < 0.0001), with no significant difference compared with the older patients (p = 0.50). No revision or complication was reported in the younger patient population at 13 years of follow-up.

Conclusions:
The monoblock uncemented DMC demonstrated excellent survival rates with no DMC-specific complications during a minimum 10-year follow-up. The dislocation rate was very low, and a younger age was not identified as a risk factor for failure. Therefore, monoblock cementless DMCs can be safely used, even in primary THA.

Shale Gas Production Prediction Based on Modified Graph Attention and Memory-Augmented Neural Networks
Authors: Hua Jinyu , Du Xin , Dong Yilun , Lu Detang 
Published: February 2025

Summary
Predicting shale gas production is crucial for optimizing shale gas well operations. However, production is influenced by numerous factors such as reservoir conditions, engineering parameters, human interventions, and interwell interference, posing significant challenges to accurate prediction. To address these complexities, we present a hybrid neural network model that combines a modified graph attention network (MGAT) with a memory-augmented neural network (MANN). MGAT enhances the extraction of spatial features from shale gas wells, while MANN uses gated recurrent units (GRUs) as its core architecture. It further incorporates production-related factors within its external memory module. MANN combines these components through an attention mechanism (AM), enabling it to efficiently extract relevant information from the external memory, thereby enhancing predictive performance. The effectiveness of the model is validated using field data from six wells with spatial relationships, and its performance is benchmarked against traditional models. Model hyperparameters are optimized using multiobjective particle swarm optimization (MOPSO). The results indicate that the proposed model achieves superior accuracy and robust generalization capabilities. Additionally, an ablation study highlights the critical role of temporal and spatial correlations for optimal model performance.
The determinants of greenhouse gas reduction levels among smallholder farmers: Insights from the adoption of climate-smart dairy Strategies in Central Kenya
Authors: Chelang'a Naomi , Mathenge Mary , Okello Dickson , Sassi Maria 
Published: February 2025

Abstract

In Kenya’s dairy sector, climate change mitigation focuses on sustainable milk production. However, dairy producers often overlook emission reduction, creating a gap between national policies and local practices. This study uses a fractional response model to examine factors influencing greenhouse gas reduction at the farm level based on survey data from 385 dairy farmers. Greenhouse gas reduction was measured using a composite index, with proxies drawn from the literature. Key factors include education, social capital, entrepreneurial orientation, awareness, and risk perception. The study recommends that the national and county governments promote and support the adoption of climate-smart dairy strategies that increase milk production while simultaneously reducing greenhouse gas emissions. This support could include technical assistance and educational programs to encourage complementary adoption by dairy farmers.
