Dune establishment drivers on the beach: narrowing down the window of opportunity
Authors: Homberger Jan-Markus , van Rosmalen Sasja , Riksen Michel , Limpens Juul
Published: July 2024

Abstract. Coastal dune development is typically initiated by the interaction between recently established dune-building vegetation and sediment transport processes. Narrowing down biotic and environmental conditions needed for vegetation establishment could improve predictions of dune initiation, yet obtaining such data on a meaningful spatial scale has proven to be challenging. We investigated grass establishment and dune initiation across a range in environmental conditions at four beach sections in the Netherlands. To understand spatial patterns of spontaneous establishment, we mapped grass seedling occurrence in July 2021 in 1899 plots. To explore the role of environmental drivers on grass establishment and ensuing dune initiation, we conducted an establishment experiment using 750 plots. We introduced seeds and rhizome pieces of Elytrigia juncea and Ammophila arenaria and monitored establishment success (shoot emergence, survival and shoot density), dune initiation and environmental conditions (soil moisture, salinity and beach bed level change) between February 2022 and March 2023. Field observations in 2021 showed that 69 – 84 % of seedlings occurred close to adult dune-building grasses, suggesting limited dispersal of diaspores, or alternatively, strong positive biotic feedback during the seedling stage. Establishment of introduced seeds and rhizomes peaked at locations with high soil moisture (at 15 – 20 %), low salinity ( < 340 mS/m) and low sediment dynamics ( –2 - +5 cm bed level change). Here, the highest dune initiation probabilities were found, with the highest probability being associated with substantial shoot emergence (330 shoots/m2). Moreover, dune initiation was associated with the middle section of the beach, characterised by moderate slopes and elevation and sufficient beach width. Our findings indicate that the window of opportunity for dune initiation is smaller than for plant establishment, as it not only depends on the arrival of plant material but also favorable environmental growing conditions. Our results can be applied to better predict dune initiation and development on the beach.

Abstract. Continental ecosystems play an important role in carbon dioxide (CO2) uptake and aerosol production, which helps to mitigate climate change. The concept of ‘CarbonSink+ potential’ enables a direct comparison of CO2 uptake and local aerosol production at ecosystem scale. Following this concept, momentary net ecosystem exchange (NEE) and number concentration of negative intermediate ions at 2.0–2.3 nm (Nneg) were analysed for boreal and hemi-boreal ecosystems across Finland and in Estonia. Nneg can tell us how effectively biogenic emissions from an ecosystem initiate the new particle formation. Four forests, three agricultural fields, an open peatland, an urban garden, and a coastal site were included focusing on summertime. We compared the NEE and Nneg at each site to the Hyytiälä forest as it is the dominant ecosystem type in Finland. Nneg was highest at the urban garden and lowest at the coastal site. The agricultural fields had higher or similar net CO2 uptake rate and higher Nneg than all studied forests. The median net CO2 uptake rate of the open peatland was only 31 % of that in Hyytiälä, while the median Nneg was 77 % of that in Hyytiälä. The median net CO2 uptake rate in the urban garden was 63 % of that in Hyytiälä, implying the importance of urban green areas in CO2 sequestration. The coastal site was a minor CO2 source. Considering the combined effect of CO2 uptake and aerosol formation and the large area of forests in Finland, the forests are the most important ecosystems helping to mitigate climate warming.
Review article: Co-creating knowledge for drought impact assessment in socio-hydrology

Published: July 2024

Abstract. Drought impacts are increasingly recognised as socially influenced processes instead of mere hydro-climatic events. Yet, drought assessments continue to be entrenched in disciplinary boundaries or limited by top-down modelling approaches, excluding those who directly experience the impacts of droughts. Transdisciplinary approaches to knowledge co-creation offer a promising opportunity to advance socio-hydrology by considering the role of politics and power, economic visions, and differential agency in shaping drought outcomes, and the experiences and knowledge of those directly affected by drought events. However, transdisciplinary approaches to drought impact studies are limited to scattered empirical cases and miss coherent theoretical and methodological guidance. Drawing from a diverse body of literature on transdisciplinarity in sustainability science, integrated water resources management, socio-hydrology, science and technology studies, and political ecology, we develop an interdisciplinary conceptual framework to guide knowledge co-creation in drought impact assessment and adaptation. The framework stands on five major dimensions: 1) stakeholder analysis, 2) the scope of the co-modelling process, 3) a shared knowledge of drought, 4) model conceptualisation and implementation, and 5) awareness of power biases and knowledge imbalances. We discuss our framework's applicability space, limitations and contributions for advancing transdisciplinary approaches in future drought impact assessments.

Published: July 2024

The European Meteorological Aircraft Derived Data Centre (EMADDC) is an operational centre in development to utilize all aircraft in the European airspace to derive upper air wind and temperature observations.The lecture will provide a high level overview of EMADDC and focus on the origination, the methods used, the EMADDC data and use cases and the unique partnerships. Also, the latest developments concerning global geographical coverage will be presented.   New air traffic control surveillance technologies such as Mode-S Enhanced Surveillance radars (Mode- S EHS) present great opportunities to obtain or derive large quantities of wind direction, wind speed and temperature observations in numbers unprecedented in the European region.EMADDC is a EUMETNET program, led by the Royal Netherlands Meteorological Institute (KNMI), for the collection, processing and dissemination of quality controlled meteorological upper air observations, based on aircraft data. Observations derived from sensors onboard aircraft are more or less instantaneously collected by Mode-S EHS radars of Air Traffic Control Centres and by local Mode-S/ADS-B receivers. By agreement, EMADDC receives these observations from Air Navigation Service Providers and local Mode-S/ADS-B operators, such as UK Met Office and Air Support, directly.EMADDC is a true partnership program linked to the meteorological and aeronautical domain and is supported by several commercial and non-commercial organisations. EMADDC is co-funded by the European Union via the Connecting Europe Facility (SESAR Deployment).Each day approximately 25 million temperature and 35 million wind observations, quality controlled, are being made available to stakeholders for use in data assimilation by NWP centres such as ECMWF, or to be used operationally in meteorological forecasting offices.Information about EMADDC is available at https://emaddc.com

Abstract. Mercury emissions from human activities persist in the environment, posing risks to humans and ecosystem, and are regulated by the Minamata Convention. Understanding the historical emissions of mercury is critical for explaining the presence of mercury in the environment. In recent years, some studies have looked at the historical trends of atmospheric emission inventory. The spatial resolution of inventories for relatively recent years have improved. However, limited inventories have combined both long time scales and high spatial resolution, which is essential for evaluating the legacy impacts of anthropogenic mercury emissions, particularly in regions with high levels of mercury emissions. Here we compile a new comprehensive point source database by fusing multiple data source, and integrate it with previous China Atmospheric Mercury Emission Model to create an annual point source and gridded emission inventory for China covering 1978–2021. Integrating point source emission inventory (P-CAME) improves the accuracy of the gridded emissions, reducing the normalized mean error for all grids by 108 % compared to not using point sources in the most recent year of 2021. The improved gridded emissions inventory notably enhances the simulation of atmospheric mercury concentrations, particularly in urban areas. P-CAME inventory resulted in a 20–23 % reduction in the normalized mean bias. The improved gridded emission data identifies potential polluted grids characterized by high cumulative emissions. It indicates that 20 % of cumulative emissions originate from just 0.3 % of the grids, primarily distributed in Gansu, Yunnan, and Hunan Provinces. These areas are predominantly dominated by non-ferrous metal smelters or a mix of emissions sources including coal-fired industries and cement production. With the improvements in simulation accuracy and the identification of highly polluted regions, this updated inventory would greatly facilitate the assessment of mercury exposure, legacy impacts, and effective management of cross-media mercury pollution.
Evolution of river regimes in the Mekong River basin over 8 decades and the role of dams in recent hydrological extremes
Authors: Dang Huy , Pokhrel Yadu
Published: July 2024

Abstract. Flow regimes in major global river systems are undergoing rapid alterations due to unprecedented stress from climate change and human activities. The Mekong River basin (MRB) was, until recently, among the last major global rivers relatively unaltered by humans, but this has been changing alarmingly in the last decade due to booming dam construction. Numerous studies have examined the MRB's flood pulse and its alterations in recent years. However, a mechanistic quantification at the basin scale attributing these changes to either climatic or human drivers is lacking. Here, we present the first results of the basin-wide changes in natural hydrological regimes in the MRB over the past 8 decades and the impacts of dams in recent decades by examining 83 years (1940–2022) of river regime characteristics simulated by a river–floodplain hydrodynamic model that includes 126 major dams in the MRB. Results indicate that, while the Mekong River's flow has shown substantial decadal trends and variabilities, the operation of dams in recent years has been causing a fundamental shift in the seasonal volume and timing of river flow and extreme hydrological conditions. Even though the dam-induced impacts have been small so far and most pronounced in areas directly downstream of major dams, dams are intensifying the natural variations in the Mekong's mainstream wet-season flow. Further, the additional 65 dams commissioned since 2010 have exacerbated drought conditions by substantially delaying the MRB's wet-season onset, especially in recent years (e.g., 2019 and 2020), when the natural wet-season durations are already shorter than in normal years. Further, dams have shifted by up to 20 % of the mainstream annual volume between the dry and wet seasons in recent years. While this has a minimal impact on the MRB's annual flow volume, the flood occurrence in many major areas of Tonlé Sap and the Mekong Delta has been largely altered. This study provides critical insights into the long-term hydrological variabilities and impacts of dams on the Mekong River's flow regimes, which can help improve water resource management in light of intensifying hydrological extremes.

Abstract. Central Asian countries, which include Kazakhstan, the Kyrgyz Republic, Tajikistan, Turkmenistan, and Uzbekistan, are known to be highly exposed to natural hazards, particularly earthquakes, floods, and landslides. With the aim of enhancing financial resilience and risk-based investment, planning to promote disaster and climate resilience in Central Asia, the European Union, in collaboration with the World Bank and the Global Facility for Disaster Reduction and Recovery (GFDRR), launched the Strengthening Financial Resilience and Accelerating Risk Reduction in Central Asia (SFRARR) regional programme. Within this framework, a consortium of national and international scientific institutions was established and tasked with developing a regionally consistent multi-hazard and multi-asset probabilistic risk assessment. The overall goal was to improve scientific understanding on local perils and to provide local stakeholders and governments with up-to-date tools to support risk management strategies. However, the development of a comprehensive risk model can only be done with the basis of an accurate hazard evaluation, the reliability of which depends significantly on the availability of local data and direct observations. This paper describes the preparation of the input datasets required for the implementation of a probabilistic earthquake model for the Central Asian countries. In particular, it discusses the preparation of a new regional earthquake catalogue harmonized between countries and homogenized in moment magnitude (Mw), as well as the preparation of a regional database of selected active faults with associated slip rate information to be used for the construction of the earthquake source model. The work was carried out in collaboration with experts from the local scientific community, whose contribution proved essential for the rational compilation of the two harmonized datasets.

Published: July 2024

Introduction: De Quevain’s disease (DD) is a Stenosing tenovaginitis involving the abductor pollicis longus (APL) and extensor pollicis brevis (EPB) within the first extensor compartment of the wrist. Despite great interest in the condition, the aetiology and pathology of this interesting disease remain unclear. Tenolysis is the surgical treatment in the majority of patients following 4 to 6 weeks of non-operative treatment trial. The study aims to report the outcome of both conservative and operative treatment of 52 patients in the study.
Materials and method: This is a retrospective study of 52 patients that was conducted at Orthopaedic Hospital Wamakko, Sokoto, Nigeria, from May 2015 to September 2021. Patients with de Quervain’s disease were first treated conservatively either on oral analgesics alone or in combination with physiotherapy, steroid injection, or both for 4 to 6-week period before tenolysis was considered.
Results: The average follow-up period was 3.2 years (range 2.4 to 6.2). The average age of presentation was 31years (range 20 to 67years). There were 16(31%) males and 36(69%) females. Majority of patients were housewives (21/40%) and falls within the age range of 20-40 years with 31(61%) patients. The affected side was 28(54%) on the left and 2(46%) on the right; 31(69%) were idiopathic, 8(15%) were associated with diabetes mellitus, 5(6%) occupational, 3(6%) with a history of trauma, 3(6%) with rheumatoid arthritis, and 2(%) with pregnancy. Out of total of 52 patients in the study, 47 (90%) were operated and 5(10%) were completely treated by non-operative management. The short-term postoperative complications that resolved few weeks following treatments were wound infections (4), superficial radial nerve neuritis (2), and Hypertrophic scar (2).
Conclusion: A more reliable long-term outcomes of treatment of patients with de Quervain’s disease is by tenolysis as the conservative treatment may fails after a 4 to 6 weeks period of trials.

Authors: Gupta Neelam , Arnestina Sarah
Published: July 2024

Introduction: Malignant nodular hidradenoma, also called as hidradenocarcinoma is a rare neoplasm arising from the eccrine glands. The tumour has a slow onset with varied disease course and is generally associated with recurrence and metastasis. It usually affects head, trunk and extremities region and commonly seen in the fifth decade. Patient presents as a solitary nodule. These lesions can arise denovo as well as from a benign nodular hidradenoma.
Case summary: We present a case of a 49 years old lady who presented with a nodule on the right side of the upper abdomen since 10 years. The swelling was gradually increasing in size and was associated with watery discharge since 3 years and intermittent pain. Examination showed it to be a 3x4cm mass in the right hypochondrium, it was mildly tender and overlying skin was normal. Wide local excision was done with rhomboid flap. Histopathological examination along with Immunohistochemical studies concluded a diagnosis of Malignant hidradenocarcinoma.
Conclusion: Literature shows few cases of Malignant hidradenocarcinoma, since the incidence is low. As it is associated with poor prognosis, hence an accurate diagnosis is very essential for treatment of the patient.

Published: July 2024

This study examines the management of social media platforms by broadcasters in the Berekete Family. Employing the Technological Determinism Theory, the research uses focus group discussions and interviews as its primary methodologies. Through availability sampling, seven interviewees and one focus group were selected. The findings reveal that Berekete Family broadcasters use a range of social media platforms, including Facebook, Twitter, WhatsApp, Facebook, Pinterest, Tumblr, Facebook Live Audio Room, and WeChat, among others such as TikTok, Google Business Messenger, Snapchat, Quora, Reddit, Medium, Ustream, Shopify X, and Google Engage. The study also reveals that broadcasters within Berekete Family screen materials before posting them on social media and analyse the profiles of those they repost from, in order to enhance the quality of their content and avoid dissemination of misinformation. Additionally, the research identifies several challenges faced by broadcasters in using social media, including misinformation, disinformation, weaponization of social media, privacy concerns, and filter bubbles. The study recommends among others that broadcasters should intensify their efforts in managing social media platforms due to the high prevalence of misinformation and privacy concerns associated with social media. The dynamic nature of social media requires broadcasters to remain vigilant and proactive in combating misinformation and safeguarding privacy rights. Strategies such as thorough content screening, fact-checking, and promoting transparency can help mitigate these risks and ensure the dissemination of accurate and reliable information.

Authors: M. Ekure , O. T. Ikwuakam
Published: July 2024

The study examined the implementation of school safety policy and the role of Parents-Teachers’ Associations (PTAs) in secondary schools across Katsina State, Nigeria. A sample of 215 PTA members was selected using multistage sampling techniques from all secondary school PTAs in Katsina State. Descriptive survey design and structured questionnaire were adopted in collecting data on awareness, threats, information sources and compliance across the state's three senatorial districts (SD). Frequency counts, percentages, means, PPMC, Analysis of Variance (ANOVA) and multiple regression analysis were employed in data analysis. Findings indicated that PTA members were generally of prime age with adequate education. Significant disparities in awareness levels were observed among the senatorial districts (SD) with Katsina South (KS) lagging behind. High levels of security threats existed across the districts. Radio and television emerged as crucial awareness sources in Katsina Central (KC) and Northern (KN). Compliance with safety roles varied across districts, with KC and KN showing higher engagement compared to southern district. ANOVA result revealed significant variations in safety roles compliance among districts, with KC demonstrating highest mean compliance. Regression analysis indicated that age negatively impacted compliance, while experience, awareness and information sources positively influenced adherence to safety roles. The study underscores the need for a comprehensive approach to addressing gaps in role compliance. It recommends prioritizing interventions for areas with low compliance rates.
A Anomalia da Política de C&T e sua Atipicidade Periférica
Authors: Dagnino Renato
Published: July 2024

As características da política de ciência e tecnologia (PCT) de países situados na periferia do capitalismo, como os da América Latina, resultam da composição de duas dinâmicas, uma inerente à PCT enquanto política pública e outra decorrente da sua condição periférica. A primeira, de natureza genérica, pode ser encontrada “em estado puro” minerando-a nos países avançados e é responsável pela anomalia (anormal, irregular) de sua PCT. Essa dinâmica faz com que a PCT apresente um desvio acentuado do padrão normal das políticas públicas, que se originam de um processo decisório no qual os atores envolvidos materializam seus projetos políticos nas agendas particulares com que nele participam. A anomalia se deve a que atores que participam em outras políticas defendendo agendas muitas vezes antagônicas, dado que resultantes de (ou condicionadas por) projetos políticos irreconciliáveis, concordam sistematicamente a respeito da orientação dada à PCT. Em consequência, por estar essa agenda decisória enviesada pela concepção da neutralidade e do determinismo da tecnociência, que entende a tecnociência (produzida pelas e para as empresas) como passível de ser “usada” para a materialização de qualquer projeto político, a PCT, ainda quando elaborada por governos de esquerda, tende a seguir a serviço dos valores e interesses do capital. A segunda dinâmica é específica de países que, como o Brasil, apresentam uma condição periférica. Aqui a PCT possui, por acréscimo, uma caraterística de atipicidade (particular, singular, inabitual). Os atores envolvidos na sua implementação, em função do contexto econômico-social e político periférico em que se inserem, manifestam comportamentos sistematicamente divergentes daqueles observados nos (e modelizados pelos) países avançados. Seus comportamentos, por essa razão, são distintos daqueles que deles se espera no momento de formulação da PCT.

Esta se dirige a la formación de estudiantes de profesorado de ciencias de educación secundaria en la NDC y su didáctica. Se presta atención tanto a los aspectos epistémicos como a los no- epistémicos en el texto de la controversia y en las cuestiones que se plantean. Asimismo, se proponen algunas recomendaciones metodológicas para su implementación y evaluación en el aula.
Fóruns de Negociações Simulados no Ensino de Engenharia, Análise de uma Estratégia Didática
Authors: de Araújo Pereira Vágner Ricardo , Massao Hayashi Carlos Roberto
Published: July 2024

Este artigo apresenta a análise de uma estratégia didática denominada Fórum de Negociação Simulado, que foi desenvolvida junto a uma turma de engenharia de uma instituição privada do interior do Estado de São Paulo. A análise foi realizada à luz de autores do campo de estudos CTS (ciência, tecnologia e sociedade) e das diretrizes curriculares nacionais para os cursos de engenharia. Os resultados indicam que os fóruns de negociações simulados são reconhecidos pelos estudantes como uma importante estratégia para a formação profissional. Destaque foi dado à interdisciplinaridade, pelo cruzamento de conhecimentos específicos de engenharia com outros aspectos, por exemplo, sociais, culturais e políticos. Além disso, foram valorizadas habilidades em construir e expor argumentos em defesa das ideias de determinado ator, representado pelo estudante no debate gerado. A oportunidade de ouvir ideias divergentes também foi considerada importante para a melhoria do processo de tomada de decisão em torno de um projeto tecnológico, cujos temas definidos para os fóruns foram caracterizados por controvérsias sociotécnicas.

A 64-year-old Japanese male with no medical history presented with night sweats and fatigue for two weeks. Chest computed tomography showed multiple mediastinal and right hilar lymphadenopathy, right lower lobe consolidation, right pleural effusion, and right pleural thickening (Figure 1a). Considering lung cancer and malignant lymphoma, a thorough examination was conducted. Blood tests showed elevated soluble interleukin 2 receptors (2421 U/ml; normal, 121-621). 18-fluorodeoxyglucose positron emission/ computed tomography showed increased uptake in lesions seen on chest computed tomography and left hilar lymph nodes (Figures 1b and 1c). Endobronchial ultrasound-guided transbronchial needle aspiration was used to perform mediastinal lymph node biopsy and pathological examination revealed a non-necrotizing epithelioid cell granuloma. Surgical biopsies of the lymph nodes and right parietal pleura were performed to exclude malignancy, and both were histologically confirmed to be non-necrotizing epithelioid cell granulomas (Figure 1e). After examination of the heart, eyes, and nerves showed no sarcoidosis, pulmonary sarcoidosis was diagnosed. Symptoms resolved without treatment after a surgical biopsy and there was a marked reduction of lesions on computed tomography five months later (Figure 1d).

Keratoconus is a progressive corneal disease affecting vision. This 12-month prospective study in Rabat evaluated the efficacy of RoseK2 rigid Gas Permeable Contact Lenses (RPGCLs) in 59 patients (113 eyes) with keratoconus. Patients were monitored by refraction, keratometry and corneal topography. RPGCLs showed a significant improvement in Best Corrected Visual Acuity (BCVA) in 86% of eyes fitted, mainly in those with myopic astigmatism. Despite good overall tolerability, minor complications such as limbal hyperemia were noted in some patients. Keratoconus geometry was closely correlated with disease progression. This study confirms that RoseK2 RPGCLs are an effective therapeutic option for keratoconus patients, but underlines the need for ongoing monitoring to detect and treat complications early.

ChordomasArachnoid cysts, also referred to as leptomeningeal cysts, are congenital lesions originating during developmental stages through the division of the arachnoid membrane, making them technically intra-arachnoid cysts. These cysts typically contain fluid that closely resembles Cerebrospinal Fluid (CSF). While arachnoid cysts are commonly benign and asymptomatic, they are relatively prevalent. Although the majority are sporadic, an increased incidence is observed in mucopolysaccharidoses, akin to perivascular spaces. Most arachnoid cysts are small in size, and about 5% of individuals may experience symptoms, often attributed to gradual enlargement leading to mass effect. There is a notable male predominance, with a ratio of approximately 3:1. Diagnosis is typically accomplished through the gold standard imaging techniques of Computed Tomography (CT) and Magnetic Resonance Imaging (MRI).

La infinidad del ma: el sentido japonés del espacio-tiempo
Authors: Barreto Barreto Juanita
Published: July 2024

"el ma se encuentra imbuido en esta cultura desde la antigüedad y se manifiesta en diferentes esferas de la sociedad. Es perceptible en las artes, en la experiencia humana, en la lengua japonesa con sus pausas acentuadas e incluso en la escritura como se vio más arriba. Por esta razón hablar del ma es nada menos que intentar hablar de un principio básico de la cultura japonesa, que es también un aspecto primordial de la sensibilidad japonesa: el concepto de espacio-tiempo como idea y experiencia unificadas."
