Published: November 2024

IntroductionOcular involvement is quite common in Behçet’s disease (BD) and may cause crucial functional complications. Even though the mechanisms of BD remain unclear, advances in gene­tic and immunological fields have improved our understanding of the immunopathogenesis of BD ocular involvement. Little is known about the expression of a proliferation-inducing ligand (APRIL) in terms of ocular involvement in BD. The objective of this study was to determine whether serum APRIL concentrations are associated with ocular involvement in patients with BD.Material and methodsThe study included 60 patients diagnosed with BD matched by age and sex to 30 healthy individuals. Every patient underwent a clinical evaluation, and the Behçet’s Disease Current Activity Form (BDCAF) was utilized to quantify disease activity. All patients underwent a comprehensive ophthalmological assessment. Serum APRIL was assessed for patients as well as controls.ResultsOne or more ocular manifestations were found in 42 BD patients (70%), while 18 patients (30%) had no ocular involvement. The mean level of serum APRIL levels was markedly elevated in BD patients, particularly those with ocular involvement, compared to both BD patients without ocular involvement and healthy individuals. A statistically significant association was determined between high APRIL concentration and development of uveitis, cataract, and hypopyon. Cutaneous lesions and arthritis were strong independent predictors for ocular involvement in BD patients.ConclusionsOverexpression of APRIL in patients with BD, particularly in terms of uveitis, cataract, and hypopyon, lends credence to the idea that B cell activating factors have an important function in BD. These findings may indicate that serum APRIL concentrations can differentiate a clinical subgroup of BD patients with ocular disease. As a result, finding a new therapeutic strategy targeting the APRIL pathway might be beneficial in BD patients suffering from ocular involvement.

Preterm birth constitutes a significant health burden in Kenya, yet there is hardly any targeted research looking at the survival and specific risk factors associated with birth of late preterm neonates (LPNs) and early term neonates (ETNs), particularly in Garissa County. While studies on preterm birth determinants have been done in Kenya, factors specifically influencing LPNs and ETNs births and their survival relative to their full-term counterparts remain understudied. Studies done on preterm in general have identified maternal age, history of preterm birth, pregnancy-induced hypertension, and prolonged premature rapture of the membrane among others as significant risk factors, but their relevance to LPNs and ETNs specifically has not been fully investigated. This study aimed to address these gaps by determining maternal as well as fetal risk factors associated with LPN and ETN births compared to full-term neonates (FTNs) born at Garissa County Referral Hospital. Further, it sought to identify predictors of survival across these neonatal groups. The study conducted at Garissa County Referral Hospital employed a prospective cohort design. Mother-neonate dyads were enrolled using convenience sampling method until the required sample was achieved. Data was collected using pretested and validated questionnaires. STATA version 17 was used for analysis. Multinomial logistic regression analysis was performed to determine Relative Risk Ratio. The P-value was set α=0.05 and P<0.05 was considered statistically significant. Survival rates were estimated using Kaplan-Meier survival analysis. Bivariate Cox regression analysis was employed to identify independent predictors at p<0.20. However, since all variables had p-values >0.02, multivariate Cox regression was not conducted. The study revealed that maternal age (P=0.042), occupation (P=0.024), ethnicity (P=0.021), religion (P=0.016) and absence of previous abortion/still birth/premature deliveries (P=0.015) were maternal related factors associated with birth of LPN, ETN and FTN. Birth weight was associated with LPN (P<0.001), while FTN had higher likelihood of delayed initiation of breastfeeding (P=0.038) but were less likely to have feeding difficulties compared to LPN and ETN (P=0.012). A comparison of fit model with the complete set of predictors with an intercept-only, or null model revealed that P-values for maternal (P=0.0175) and fetal (P<0.001) related risk factors were less than Fisher’s value of 0.05, hence the null hypothesis was rejected. The Kaplan-Meier survival analysis revealed high survival rates across all gestational age categories, with 100% survival among LPNs. In conclusion, the study showed that maternal- and fetal-related risk factors associated with LPNs and ETNs are distinct from those of FTNs.

The role of refractive indices in measuring mineral dust with high-spectral-resolution infrared satellite sounders: application to the Gobi Desert
Authors: Alalam Perla , Ducos Fabrice , Herbin Hervé 
Published: November 2024

Abstract. Mineral dust significantly influences the Earth's climate system by affecting the radiative balance through the emission, absorption and scattering of solar and terrestrial radiation. Estimating the dust radiative effect remains challenging due to the lack of detailed information on the physical and chemical properties of dust. High-spectral-resolution instruments in the infrared (IR) spectrum, such as the Infrared Atmospheric Sounding Instrument (IASI), have demonstrated the ability to quantify these aerosol properties. A crucial parameter for characterizing mineral dust from space is the complex refractive index (CRI), as it links the dust's physical and chemical properties to its optical properties. This paper examines the impact of six prior laboratory CRI datasets to improve the characterization of dust microphysical properties using IASI. The CRIs include older measurements obtained through the classical pellet method, commonly employed in mineral dust applications, as well as newer datasets that incorporate the latest advancements in laboratory measurement techniques for aerosol generation. These datasets are tested on IASI measurements during a dust storm event over the Gobi Desert in May 2017. We evaluate the sensitivity of IASI to different CRI datasets using the Atmospheric Radiation Algorithm for High-Spectral Resolution Measurements from Infrared Spectrometer (ARAHMIS) radiative transfer algorithm and explore the datasets' impact on retrieving size distribution parameters by mapping their spatial distributions. The results indicate that the laboratory CRI datasets decrease the total error in the covariance matrix by 30 %. In addition, we assess the ability to accurately reconstruct IASI detections and the extent to which we can retrieve the microphysical properties of dust particles. The choice of CRI significantly impacts the accuracy of dust detection and characterization from satellite observations. Notably, datasets that incorporate recent aerosol generation techniques with higher spectral resolution and samples from the case study region show improved compatibility with IASI observations. The outcomes of this research emphasize two key points: the crucial link between chemical composition of dust and its optical properties and the importance of considering the specific composition of the CRI dataset for improved retrieval of the microphysical parameters. Furthermore, this study highlights the critical role of ongoing enhancements in CRI measurement approaches, as well as the potential of high-spectral-resolution infrared sounders for aerosol atmospheric investigation and for understanding the radiative impacts of sounders.

Abstract. Climate change increases the risk of wildfires and floods in the Mediterranean region. Yet, wildfire hazards are often overlooked in flood risk assessments and treated in isolation, despite their potential to amplify floods. Indeed, by altering the hydrological response of burnt areas, wildfires can lead to increased runoff and amplifying effects. This study aims to comprehensively assess flood risk using a multi-hazard approach, considering the effect of wildfires on flood risk, and integrating diverse socio-economic indicators with hydrological properties. More specifically, this study investigates current and future flood risks in the Ebro River basin in Spain for the year 2100 under the Shared Socioeconomic Pathway 1-2.6 (SSP1-2.6) and SSP5-8.5 scenarios, taking into account projected socio-economic conditions and the effect of wildfires. An analytical hierarchy process (AHP) approach is employed to assign weights to various indicators and components of flood risk based on insights gathered from interviews with seven experts specializing in natural hazards. Results show that the influence of wildfires on the baseline flood risk is not apparent. Under the SSP1-2.6 scenario, regions with high flood risk are expected to experience a slight risk reduction, regardless of the presence of wildfires, due to expected substantial development in adaptive capacity. The highest flood risk, almost double compared to the baseline, is projected to occur in the SSP5-8.5 scenario, especially when considering the effect of wildfires. Therefore, this study highlights the importance of adopting a multi-hazard risk management approach, as reliance solely on single-risk analyses may lead to underestimating the compound and cascading effects of multi-hazards.

Приведены актуализированные положения теории базирования и обновленный состав баз: установочная, направляющая, опорная, двойная направляющая, двойная опорная и тройная опорная. Комбинации баз образуют пять комплектов, каждый из которых можно реализовать с помощью явных или скрытых баз или их совмещений. Показано, что наибольшие трудности вызывает базирование предмета комплектами скрытых баз, а особенностью базирования предмета скрытыми базами является определение положения опорных точек с помощью точек контакта предмета, реализуемых установочными элементами. При базировании предмета скрытой базой положение опорной точки определяется самоцентрирующим механизмом с помощью точек контакта с предметом базирования. Рассмотрены всевозможные схемы конструктивных решений базирования и закрепления предметов комплектами из скрытых баз в самоцентрирующихся механизмах.
The updated provisions of the basing theory and the updated composition of the bases are given: installation, guide, support, double guide, double support and triple support. Base combinations form five sets, each of which can be implemented using explicit or hidden bases or their combinations. It is shown that basing an object with sets of hidden bases causes the greatest difficulties, and a feature of basing an object with hidden bases is determining the position of reference points using the contact points of the object, implemented by the installation elements. When basing an object with a hidden base, the position of the reference point is determined by a self-centering mechanism using points of contact with the basing object. Various schemes of constructive solutions for basing and fixing objects in sets of hidden bases in self-centering mechanisms are considered.

This paper presents practical application of digital image correlation (DIC) method for experimental investigation of significantly nonhomogeneous residual stress (RS) fields via "large" hole drilling method. Specifically designed polymer material specimens, incorporating the authors' proposed technique, are employed to create a discontinuous piecewise-linear RS field. Recommendations regarding the optimal relationships between the indicator hole diameter and the geometric parameters of the specimen are developed based on an analysis of numerical simulation results of a series of typical tasks. Special considerations and practical recommendations, including volume, size of the localization zone of the initial experimental data, and the optimal number of series members used for the analytical representation of the sought RS distribution, are discussed to ensure sufficiently high result accuracy.

Abstract
This article analyzes the poems gathered and published by Ignacio de Saavedra, public prosecutor of the city of Cádiz, that participated in the festivity of plague’s remission in 1681. It argues the poetic and iconographic project of the volume aims to influence the perceptions of the political management of epidemics in the eyes of local survivors. In so doing, plague poetry reinstated the social and political order temporarily upended by plague and gave the city a sense of pride and identity.
