Abstract. Production of oil and gas in Romania, one of the largest producers in the European Union (EU), is associated with substantial emissions of methane to the atmosphere and may offer high emission mitigation potential to reach the climate objectives of the EU. However, comprehensive quantification of emissions in this area has been lacking. Here we report top-down emission rate estimates derived from aircraft-based in situ measurements that were carried out with two aircraft during the 2019 ROmanian Methane Emissions from Oil and gas (ROMEO) campaign, supported by simulations with atmospheric models. Estimates from mass balance flights at individual dense production clusters and around larger regions show large variations between the clusters, supporting the important role of individual super-emitters, and possibly show variable operation practices or maintenance states across the production basin. Estimated annual total emissions from the southern Romanian oil and gas (O&amp;G) infrastructure are 227 ± 86 kt CH4 yr−1, consistent with previously published estimates from ground-based site-level measurements during the same period. The comparison of individual plumes between measurements and atmospheric model simulations was complicated by unfavorable low-wind conditions. Similar correlations between measured and simulated CH4 enhancements during large-scale raster flights and mass balance flights suggest that the emission factor determined from a limited number of production clusters is representative of the larger regions. We conclude that ground-based and aerial emission rate estimates derived from the ROMEO campaign agree well, and the aircraft observations support the previously suggested large under-reporting of CH4 emissions from the Romanian O&amp;G industry in 2019 to United Nations Framework Convention on Climate Change (UNFCCC). We also observed large underestimation from O&amp;G emissions in the Emissions Database for Global Atmospheric Research (EDGAR) v7.0 for our domain of study.

Abstract. The full understanding of climate feedbacks responsible for the amplification of deglaciations requires robust chronologies for these climate transitions, but in the case of marine records, radiocarbon chronologies are possible only for the last glacial termination. Although the assumed relationships between the marine isotopic record and the orbital parameters provide a first-order chronology for glacial terminations, an independent chronological control allows the relationships between orbital forcing and the climate response to be evaluated over multiple previous terminations. To assess this, we present geochemical records from the western Mediterranean, including two speleothems and one marine sediment core. The most notable speleothem, the so-called RAT, established a new long terrestrial climate record for this region, spanning Marine Isotope Stages from MIS 11 to MIS 7. Its absolute U / Th dates provide an exceptional chronology for the glacial terminations IV, III, and III.a. The onset of these three glacial terminations was marked by rapid δ18O depletions, reflecting ocean freshening by ice melting, thus providing an excellent tie point for regional marine records also sensitive to such freshening. This is exemplified by new δ18O data of the Ocean Drilling Program (ODP) 977 site from the Alboran Sea, where the speleothem chronology was employed to adjust its age model. The new chronologies reveal an earlier onset of the deglacial melting for the TIV and TIII.a that is in contrast to the generally accepted marine chronologies and indicates that the duration of these deglaciations was variable, with TIV being particularly longer (∼ 20 kyr). This study also supports that the onset of deglacial melting always occurred during a declining precession index, while a nonunique relation occurred with the obliquity parameter.
BEYOND THE PROMOTION OF ECONOMIC COOPERATION: THE ECONOMIC COMMUNITY OF WEST AFRICAN STATES PEACEKEEPING INVOLVEMENTS IN WEST AFRICA
Authors: Okolie Ugo Chuks , ORHERO Ejogba Abraham 
Published: February 2025

In order to raise the living standards of its people, maintain and improve economic stability, foster relations among Member States, and contribute to the advancement and development of the African continent, Economic Community of West African States (ECOWAS) was established. Its goal is to promote cooperation and integration that will result in the creation of an economic union in West Africa. According to a set of guiding principles, such as impartiality, the parties' consent, and the non-use of force unless necessary for self-defense, a third party intervention known as "peacekeeping" is conducted. The study examines the role played by ECOWAS in preserving stability and peace on the African continent, focusing in particular on the ECOMOG intervention in Liberia, Sierra Leone, and Guinea Bissau. The regional security complex theory was accepted. The research was qualitative, and its historical analysis heavily drew on secondary sources. The essence of the resolutions of the UN Security Council and the ECOWAS Mediation and Security Council, and consequently the legal foundation for peacekeeping and peace enforcement are contained in peace agreements. As a result, peace agreements are essential to the management and resolution of conflicts. However, it is erroneous to assume that the heads of armed factions are sane political actors motivated by genuine grievances and that they will thereby agree to mediated agreements. The offering of carrots (the confidence-building approach) must therefore be combined with strong diplomacy supported by a credible enforcement capacity in order for peace to be successfully implemented in the West African region. The study recommends, among other things, that the framework for the ECOWAS legal system governing peace and security should be the member states. This is because the majority of democracies in the sub-region elect postcolonial states with a predominance of coloniality of power disguising itself as democracy and causing conflicts in the majority of countries within the West African security complex, ECOWAS must exert pressure on its member states to step up their efforts to improve democracy in their respective countries.

Many epidemics and deadly diseases that sowed fear in the world in the 20th century. the new coronavirus nicknamed by Covid-19 has appeared. It was necessary to reveal the symptoms, complications and diseases that characterize COVID-19 patients in relation to several parameters, frequency and mode of admission into hospitals. The main goal of our work is to make a study followed by an analysis of the resolution of COVID-19 at the level of a city in Algeria. In this work we studied the evolution of COVID-19 in a certain city in Algeria named Batna between 2019 and 2022 using the complete inventory method and analysis by the SPSS software taking as variables: Sex, age group, common and mode of admission to hospital facilities and as sections: symptoms, complications and diseases. The data were taken from the epidemiology department of CHU BATNA, and the study is represented by tables and representative diagrams. We based our study on the most common symptoms of COVID-19 such as fever, weakness and cough on the other hand; the most common symptoms of COVID-19 in patients like sore throat, runny nose, ... This fact has been confirmed by some results. We found that there are statistically significant differences in the importance of the sex variable with the axis of symptoms in favor of the male sex. Some assumptions can be made about the variables and their relationship to the sections: Gender, Age group and others.

De toepassing van het lex certa-beginsel door de hoogste Nederlandse bestuursrechters: uniformering gewenst?
In de rechtspraak van de hoogste bestuursrechters kunnen verschillen worden geconstateerd bij de uitleg en toepassing van het lex certa-beginsel. Dat bevestigt ook de recente rechtspraak uit de periode oktober 2022 tot oktober 2024. De redenen voor het bestaan van deze verschillen worden uit de rechtspraak niet duidelijk. Hoewel deze verschillen niet altijd groot zijn, is gelet op het uitgangspunt van rechtseenheid uniformering wenselijk. In deze bijdrage worden daarvoor een aantal suggesties gedaan.
Een risicovolle nuancering van asbestverdachtheid

Een risicovolle nuancering van asbestverdachtheid. Annotatie bij hof Amsterdam 1 augustus 2024, ECLI:NL:GHAMS:2024:2166
Na de Tweede Wereldoorlog is in Nederland op grote schaal gebruikgemaakt van asbesthoudende materialen in de bouw, waaronder ook in de woningbouwsector. In dit arrest komt het hof Amsterdam tot vrijspraak van een verdachte die voor de verwijdering van een asbesthoudende dakkapel uit de jaren tachtig niet een asbestinventarisatierapport heeft laten opmaken. Daarnaast nuanceert het gerechtshof de asbestverdachtheid van woningen die zijn gebouwd vóór 1994. Dat laatste lijkt niet alleen juridisch onjuist, maar kan mogelijk ook nadelige gevolgen hebben voor de handhaving van het Asbestverwijderingsbesluit en daarmee de volksgezondheid.

O câncer colorretal (CCR) é uma das neoplasias mais comuns e fatais no mundo, com alta incidência em países ocidentais. Fatores como dieta inadequada, sedentarismo e predisposição genética contribuem para o aumento dos casos. Os principais sintomas incluem dor abdominal, alterações no hábito intestinal, sangramentos e perda de peso. Nos estágios iniciais, a doença pode ser assintomática, o que dificulta a detecção precoce. O rastreamento é essencial para a redução da mortalidade. A detecção precoce e o tratamento adequado são fundamentais para melhorar os prognósticos. OBJETIVO: compilar e analisar criticamente as pesquisas já realizadas, oferecer uma visão abrangente dos avanços no diagnóstico, manejo clinico, cirúrgico e prognóstico do câncer de colorretal. METODOLOGIA: Trata-se de uma revisão de literatura sobre o cancecolorretal. A pesquisa utilizou a Biblioteca Virtual em Saúde (BVS) como fonte de dados e aplicou termos específicos como "câncer de colorretal", "diagnóstico" e "tratamento", com filtros de idioma (português, inglês e espanhol) e período de publicação (2019-2024). Foram selecionados 22 estudos após aplicação dos critérios de inclusão e exclusão. Embora não necessite de aprovação ética, a revisão segue boas práticas científicas. DISCUSSÕES: O câncer colorretal é uma das principais causas de morbimortalidade mundial, originando-se, geralmente, de pólipos adenomatosos no cólon ou reto. O diagnóstico precoce é essencial para melhorar os resultados terapêuticos, sendo realizado por meio de exames de rastreamento, como a colonoscopia, a pesquisa de sangue oculto nas fezes e, mais recentemente, o teste de DNA fecal. O tratamento do CCR depende do estágio da doença, sendo a cirurgia a principal modalidade terapêutica nos estágios iniciais. Para casos mais avançados, a quimioterapia, terapias-alvo e imunoterapia são utilizadas, com o objetivo de prolongar a sobrevida e melhorar a qualidade de vida. O tratamento personalizado, baseado no perfil molecular do tumor, tem mostrado avanços significativos, proporcionando terapias mais eficazes e menos tóxicas. A adesão ao rastreamento e o acesso equitativo aos tratamentos são fundamentais para reduzir a mortalidade associada à doença. CONCLUSÃO: O CCR é uma das neoplasias mais comuns e fatais no mundo, com alta incidência em países ocidentais. Fatores como dieta inadequada, sedentarismo e predisposição genética contribuem para o aumento dos casos. Os principais sintomas incluem dor abdominal, alterações no hábito intestinal, sangramentos e perda de peso. Nos estágios iniciais, a doença pode ser assintomática, o que dificulta a detecção precoce. O rastreamento é essencial para a redução da mortalidade.

Assessment of the institutional arrangements for the Payments for Environmental Services (PES) implementation for watershed conservation: The case of Mount Hamiguitan Range Wildlife Sanctuary (MHRWS)
Authors: Cereno Donnell C , Roxas Alita T 
Published: February 2025

This study examined institutional factors that may facilitate or constrain the implementation of Payments for Environmental Services (PES) for watershed conservation in the Mount Hamiguitan Range Wildlife Sanctuary (MHRWS). Focusing on sustaining the water supply from MHRWS watersheds to nearby communities, the assessment drew from key informant interviews and secondary data. Enabling factors for PES implementation include supportive national environmental laws and programs implemented locally; stakeholder engagement, which has waned but has the potential to be revitalized; and clear property rights for the Mandaya indigenous community and farmers in the watersheds. However, key constraints, such as limited institutional capacity and the effects of the absence of PES institutionalization, were evident. Institutional challenges include limited PES knowledge, inadequate water management data, weak representation of indigenous people and tenured farmers in the PAMB, and declining funds for protected area management. The lack of a national PES law or framework has disrupted conservation efforts due to government leadership transitions and can similarly affect PES initiatives. The findings suggest prioritizing capacity building, stakeholder engagement, and sustainable funding as management directions. At the same time, policies should emphasize institutionalizing PES, strengthening tenure rights, and aligning local actions with national environmental laws. Participation by MHRWS lead bodies in the ongoing national P-WES institutionalization process can catalyze PES implementation. This involvement can enhance their capacity to address current challenges while inspiring stakeholders to adopt PES—particularly P-WES—for effective watershed management and sustainable water supply.
Las secuencias de reparación en el Diálogo de la lengua de Juan de Valdés y El Deleitoso de Lope de Rueda
Authors: Juarranz Jiménez Rosalía 
Published: February 2025

This article analyses repair sequences in a corpus consisting of two literary works from the 16th century: Diálogo de la lengua and El Deleitoso. These two texts contain characteristic features of conversational speech, and they are suitable for conducting a pragmatic and discourse analysis study of the problems that motivate repairs and of the linguistic forms used to implement them. The examples from the corpus are examined in depth, and the results indicate a correlation between the two main mechanisms for requesting repair (echo questions and echo questions with interrogative word) and the type of problem that motivates repair. The analysis of repair sequences is also used as a framework for describing literary dialogues in the two works contained in the corpus.
En este trabajo se analizan las secuencias de reparación recogidas en un corpus elaborado a partir de dos obras literarias del siglo XVI: el Diálogo de la lengua y el Deleitoso. Estas obras se toman como muestra de textos con una alta mímesis conversacional para llevar a cabo un análisis pragmático y discursivo de las causas de la reparación y las formas lingüísticas empleadas. Nuestro estudio, además de explicar en detalle los ejemplos recogidos en el corpus, demuestra la existencia de una correlación entre los dos principales mecanismos de petición de reparación (las interrogativas eco y las interrogativas eco con palabra interrogativa) y las causas que motivan la reparación. Además, se estudian las secuencias de reparación en relación con la caracterización de las obras literarias analizadas, caracterizándose el diálogo literario a partir de los usos lingüísticos representados.
