Published: July 2023

предложен оптический метод изучения структуры короткоживущих, нестационарных и неустойчивых образований низкотемпературной плазмы, использующий ее рефракционные свойства. На основе имеющихся наблюдательных данных об оптических свойствах шаровой молнии и решения интегрального уравнения Абеля получены возможные радиальные распределения показателя преломления, концентрации заряженных частиц и температуры. Правильность предлагаемого подхода проверена в исследовании рефракции света при прохождении через сферический фронт пропановоздушного пламени. Методом цифровой фотометрии проведены сравнительные расчеты температурных полей в пламени, шаровой молнии и «однокомпонентном плазмоиде».
this study proposes an optical method for studying the structure of short-lived, non-stationary low-temperature plasmoids using the refractive properties of the plasma. We obtained possible radial distributions of the refractive index, concentration of charged particles, and temperature from the available observations of the ball lightning optical properties and the solution of the Abel integral equation. We verified the proposed method by measuring the refraction of light passing through the spherical front of a propane-air flame. The temperature fields in the flame, ball lightning, and “one-component plasmoid” were compared with digital photometry.

Abstract. River corridors are fundamental components of the Earth system, and their biogeochemistry can be heavily influenced by processes in subsurface zones
immediately below the riverbed, referred to as the hyporheic zone. Within the hyporheic zone, organic matter (OM) fuels microbial respiration, and
OM chemistry heavily influences aerobic and anaerobic biogeochemical processes. The link between OM chemistry and respiration has been hypothesized
to be mediated by OM molecular diversity, whereby respiration is predicted to decrease with increasing diversity. Here we test the specific
prediction that aerobic respiration rates will decrease with increases in the number of unique organic molecules (i.e., OM molecular richness, as a
measure of diversity). We use publicly available data across the United States from crowdsourced samples taken by the Worldwide Hydrobiogeochemical
Observation Network for Dynamic River Systems (WHONDRS) consortium. Our continental-scale analyses rejected the hypothesis of a direct limitation of
respiration by OM molecular richness. In turn, we found that organic carbon (OC) concentration imposes a primary constraint over hyporheic zone
respiration, with additional potential influences of OM richness. We specifically observed respiration rates to decrease nonlinearly with the ratio
of OM richness to OC concentration. This relationship took the form of a constraint space with respiration rates in most systems falling below the
constraint boundary. A similar, but slightly weaker, constraint boundary was observed when relating respiration rate to the inverse of
OC concentration. These results indicate that maximum respiration rates may be governed primarily by OC concentration, with secondary influences
from OM richness. Our results also show that other variables often suppress respiration rates below the maximum associated with the
richness-to-concentration ratio. An important focus of future research will identify physical (e.g., sediment grain size), chemical (e.g., nutrient
concentrations), and/or biological (e.g., microbial biomass) factors that suppress hyporheic zone respiration below the constraint boundaries
observed here.
Improved catalog of NOx point source emissions (version 2)
Authors: Beirle Steffen , Borger Christian , Jost Adrian , Wagner Thomas 
Published: July 2023

Abstract. We present an updated (v2) catalog of NOx emissions from point sources as derived from TROPOspheric Monitoring Instrument (TROPOMI) measurements of NO2 (Products Algorithm Laboratory (PAL) product) combined with wind fields from ERA5.
Compared to version 1 of the catalog (Beirle et al., 2021), several improvements have been introduced to the algorithm. Most importantly, several corrections are applied, accounting for the effects of plume height on satellite sensitivity, 3D topographic effects, and the chemical loss of NOx,
resulting in considerably higher and more accurate NOx emissions.
In addition, error estimates are provided for each point source, taking into account the uncertainties of the individual retrieval steps. The v2 catalog is based on a fully automated iterative detection algorithm of point sources worldwide.
It lists 1139 locations that have been found to be significant NOx sources.
The majority of these locations match power plants listed in the Global Power Plant Database (GPPD).
Other NOx point sources correspond to cement plants, metal smelters, industrial areas, or medium-sized cities. The emissions listed in v2 of the catalog show good agreement (within 20 % on average) to emissions reported by the German Environment Agency (Umweltbundesamt, UBA) as well as the United States Environmental Protection Agency (EPA). The data are publicly available at https://doi.org/10.26050/WDCC/No_xPointEmissionsV2 (Beirle et al., 2023).

Narrativas de resistencia de las mujeres saharauis desde las pedagogías feministas y decoloniales
Authors: Martínez Martín Irene , Bejarano Franco María Teresa , Tellez Delgado Virtudes 
Published: July 2023

En un contexto de constante conflicto y refugio el pueblo saharaui tiene mucho que aportar desde las vivencias personales y colectivas de lucha y resistencia y, en particular, las mujeres saharauis como lideresas, organizadoras y sostenedoras de vida en este contexto atravesado por múltiples violencias.
Este artículo tiene un doble objetivo, por un lado, recoger y analizar las narrativas de las mujeres saharauis que realizan tareas de organización social, política y educativa en los campamentos para extraer conocimiento pedagógico desde los feminismos decoloniales; y por otro, atribuir a la formación inicial docente mejores competencias educativas críticas. Se aplica el método de investigación biográfico-narrativo en formato discursivo a partir de 12 entrevistas semi-estructuradas que recogen experiencias de vida en el contexto de la wilaya y en situación de exilio- refugio.
Para el análisis se han propuesto cuatro categorías que han guiado los protocolos de entrevistas: memoria y vivencia política del conflicto; rol colectivo de las mujeres como sostenedoras de vida; cultura colectiva de resistencia frente al conflicto; y elementos de la pedagogía feminista decolonial.
Los resultados extraídos giran en torno a las estrategias que las mujeres saharauis tienen frente a la situación de conflicto, así se destaca: la construcción de espacios propios donde se trasciende lo público y lo privado, las labores de organización política junto al sostenimiento de la vida; la construcción de una identidad cultural y política de resistencia decolonial; la importancia de la educación comunitaria y tradicional en los espacios femeninos intergeneracionales; la necesidad de contar con redes transnacionales de apoyo y de diseñar estrategias de resistencia transformadoras con proyección a futuro. Estos elementos se discuten desde los aportes de las pedagogías feministas, decoloniales e interseccionales como marco epistémico y de acción para una formación inicial docente más crítica y comprometida.
Challenging the ‘Western’ Narrative: Africa and the Migration Crisis
Authors: Nzally Jimmy Hendry 
Published: July 2023

This article seeks to give a critical analysis on the ongoing migration discourse both from an academic and policy perspective. It provides a perspective of Africa’s long history of hosting migrants and refuges including Europeans. It therefore addresses the question as to whether African states have lived up to their refugee and migration protection commitment. By doing so, it also criticizes Europe’s unfair, aggressive, and inhumanly migration policy towards migrants, asylum seekers, and refugee, particularly Africans. By analyzing existing data on migration, this article debunks the notion that a migration crisis is by nature an African one as if Africans are the only ones entering Europe. This scapegoating of Africans by portraying the continent at disarray will be examined closely. In that light, the article employs an Africanist line of thinking to deconstruct this narrative. This includes referenced interviews offering perspectives on this subject matter. The key question asked is as to what extent the EU should be accountable for human rights’ violation in third countries? The focus is on European Externalization of its borders to third countries in particular North Africa. It takes as an example the 2022 Melilla massacre described by western authorities as a ‘stampede’ in which migrants and refugees were killed while trying to enter Spain. This massacre took place at the borders between Morocco and Spain.

COVID – 19 PANDEMIC AND COUNTER INSURGENCY (COIN) OPERATIONS IN THE NORTH EAST OF NIGERIA: IMPERATIVE OF TECHNOLOGY
Authors: EGBUTA UGWUMBA , YANET Aishatu Morido 
Published: July 2023

Abstract
Boko Haram insurgency brings with it unprecedented consequences, particularly in records of multiple deaths and devastating effects on socio-economic dynamics of the nation. Since no state would stay without responding to threats to its national security, the federal government of Nigeria adopted both kinetic and non-kinetic approaches to counter the impact of terrorism on its shores. With several attacks from Boko Haram and the resultant consequences in terms of deaths, displacement and economic damages, the group has remained a potent force particularly in the North East and the Sahel region. In the midst of these contending realities is the Corona Virus Disease (COVID -19) that broke out from Wuhan, China in December 2019. Within the space of few months, the outbreak spiraled into a public health emergency and global pandemic; with rapid spread, high casualty rate and negative impacts on global health and economy. Accordingly, Nigeria like other nations was hit by the virus, causing disruption in its already fragile economy coupled with internal security threats. As a measure of containment, the global lockdown measures resulted in less economic patronage which translated into vulnerabilities like crime rate increase. While other countries were seeking answers to the question of health security, Nigeria was faced with the double tragedy of Boko Haram on one hand; and health insecurity on the other with attendant consequences. In this view, application of technology in combating insecurity as well as health emergencies will be the way to go, particularly, in a world that is technologically driven. This paper examines the imperative of technology in counter insurgency operations. It will adopt the historical approach in its analysis to build a pragmatic approach to reversing the trend.

Subjectivité et engagement dans Scènes de lutte de classe au Portugal de Robert Kramer et Philip J. Spinelli
Authors: Léon Benjamin 
Published: July 2023

C’est au milieu des années 1970 que les cinéastes américains Robert Kramer et Philip J. Spinelli quittent une Amérique en transition – celle de l’après-Vietnam – pour un territoire non moins en transition : le Portugal de l’après-révolution des Oeillets. Ne cherchant pas à inscrire l’événement historique sur les semaines qui suivirent avril 1974 et qui menèrent à la chute de l’Estado Novo (Deuxième République), les réalisateurs se concentrent sur un temps plus long, soit jusqu’en 1976. Ainsi, ils interrogent de façon linéaire la tension fulgurante et chaotique de la Révolution, tout autant que les potentialités politiques réelles du mouvement pour le pouvoir populaire. À travers un travail de montage fragmentaire des événements, Kramer et Spinelli établissent, dans Scènes de lutte de classe au Portugal (1977), un contrepoint analytique distancié mais non moins ambigu d’une écriture de l’histoire in situ. Sans minorer la place de Spinelli en tant que coréalisateur, nous chercherons à recentrer notre propos sur la subjectivité assumée de Kramer dans l’énonciation des faits – la chronique d’une révolution –, laquelle est indissociable de son engagement politique – le positionnement marxiste.

In December 2019, China announced a SARS CoV-2 virus in the Wuhan market, later announced by the WHO as the COVID-19 pandemic with a global impact on public health. The aim of this review was focused on determining if there are disparities in the impact of COVID-19 associated with the average salary.
Methodology: A documentary review of information detected in the network [Data México] among other sources was carried out, using the keywords; covid-19 pandemic, confirmed cases of covid-19, socioeconomic status and covid-19, socioeconomic disparity and covid-19 as well as cross-checking of confirmed cases of COVID-19, the number of deaths from this cause and salary average of each of the federative entities. Statistical analysis was performed in SPSS-Ver 23.
The results denote marked socioeconomic disparities, the impact of covid-19 does not reside in the biology of the virus, but in particularities of the patient, social environment, and other predictors such as marginalization and comorbidities.
Conclusion: Economic disparities, municipal marginalization constitute a predictor of presenting severe forms of COVID-19, an independent association of other predictors such as age and cardio-metabolic comorbidities.
Do emergency medicine residents have access to healthy food options during work hours?
Authors: Kontrick Amy V. , Thakkar Pankti M. , Mycyk Mark B. 
Published: July 2023

AbstractBackgroundRelatively little data describe how diet and food choices impact trainee well‐being despite evidence that diet impacts both physical and mental health. The objective was to describe food options available to emergency medicine (EM) residents when on duty.MethodsA survey utilizing closed‐ended, binary, rank‐order responses was developed by experts in graduate medical education and wellness; it was piloted, revised, and then electronically distributed to 211 EM residency programs over 2 weeks in 2021. The program director (PD) or associate PD was invited to participate.ResultsA total of 114 EM programs participated (54%). The primary teaching site included 43 community hospitals, 23 county hospitals, and 48 university hospitals. Resident access to an onsite hospital cafeteria was most common (97%); other onsite options were vending machines (87%), fresh food fridges (34%), national chains (32%), local restaurants (25%), food trucks (30%), and farmer's markets (11%). More than one‐third (38%) reported that onsite options did not include healthy food, 26% reported being dissatisfied with onsite food, and 35% rarely or never purchased food onsite. Most programs (89%) do not have a dedicated “meal break” for residents while on duty. Few residency programs include diet or nutrition classes or counseling. When programs sponsor meals during residency events, nutritional value and dietary considerations were ranked less important than cost of food and convenience.ConclusionsAccess to healthy food options is not always available during scheduled resident work hours, and dedicated meal breaks are infrequent. These data should inform institutional initiatives to improve the health and well‐being of resident physicians.

Published: July 2023

Key Clinical MessageIL‐36 might play a role as an initial immune mechanism against chikungunya fever, and regulating IL‐36 production could be a potential treatment approach for this condition.AbstractTwo Japanese siblings visited Cook Islands in 2015 and developed Chikungunya fever upon their return. The sister experienced high fever, joint pain, and leg swelling, while the brother had joint pain and a rash. Both siblings had a confirmed CHIKV infection and continued to experience prolonged joint pain, with the sister enduring chronic pain for about a year. In this study, the levels of IL‐36 in the serum of two siblings who were infected with chikungunya fever during the acute and recovery phases were compared using ELISA. IL‐36 is a cytokine that induces inflammation and is produced by cells in tissues such as the skin and mucosa. It was hypothesized that IL‐36 may be involved in persistent joint pain after chikungunya fever infection. Both siblings experienced long‐lasting joint pain after chikungunya fever infection. The levels of IL‐36α and IL‐36β decreased by 56 days after infection. In the results, IL‐36 plays an important role in host immunity and may act as part of the immune response during chikungunya virus infection. Inhibiting the release of IL‐36 could be a promising approach for developing new treatment methods for chikungunya fever.
