Depth-dependence of soil organic carbon additional storage capacity in different soil types by the 2050 target for carbon neutrality
Authors: Chirol Clémentine , Séré Geoffroy , Redon Paul-Olivier , Chenu Claire , Derrien Delphine
Published: May 2024

Abstract. Land planning projects aiming to maximise soil organic carbon (SOC) stocks are increasing in number and scope. In response, a rising number of studies assess SOC additional storage capacities over regional to global spatial scales. In order to provide realistic values transferrable beyond the scientific community, SOC storage capacity assessments should consider the timescales over which this capacity might be reached, considering the effects of C inputs, soil type and depth on soil C dynamics. This research was conducted in a 320 km2 territory in North-eastern France where eight contrasted soil types have been identified, characterized and mapped thanks to a high density of fully-described soil profiles. Continuous profiles of SOC stocks were interpolated for each soil type and land use (cropland, grassland or forest). Depth-dependent estimates of maximum SOC additional storage capacity using the Hassink equation and a data-driven approach were compared. We used a novel method that uses the data-driven approach to constrain C inputs in a simple model of depth-dependent C dynamics to simulate SOC accrual over 25 years, and mapped the SOC stocks, maximum additional storage capacity and stock evolution. SOC stocks and maximum additional storage capacities are highly heterogenous over the region of study. Median SOC stocks range from 78–333 tC ha-1. Data-driven maximum SOC additional storage capacities vary from 19 tC ha-1 in forested Leptosols to 197 tC ha-1 in grassland Gleysols. Estimations of SOC maximum additional storage capacities based on the Hassink approach led to unrealistic vertical distributions of SOC stock, with particular overestimation in the deeper layers. Crucially, the simulated SOC accrual over 25 years was five times lower than the maximum SOC additional storage capacity (0.57 and 2.5 MgC respectively). Further consideration of depth-dependent SOC dynamics in different soil types is therefore needed to provide targets of SOC storage over timescales relevant to public policies aiming to approach carbon neutrality by 2050.

Abstract. Lakes and ponds experience anthropogenically forced changes that may be non-linear and sometimes initiate ecosystem feedbacks leading to tipping points beyond which impacts become hard to reverse. In many cases climate change is a key driver, sometimes in concert with other stressors. Lakes are also important players in the global climate by ventilating a large share of terrestrial carbon (C) back to the atmosphere as greenhouse gases and will likely provide substantial feedbacks to climate change. In this paper we address various major changes in lake ecosystems and discuss if tipping points can be identified, predicted, or prevented, as well as the drivers and feedbacks associated with climate change. We focus on potential large-scale effects with regional or widespread impacts, such as eutrophication-driven anoxia and internal phosphorus (P) loading, increased loading of organic matter from terrestrial to lake ecosystems (lake “browning”), lake formation or disappearance in response to cryosphere shifts or changes in precipitation to evaporation ratios, switching from nitrogen to phosphorus limitation, salinization, and the spread of invasive species where threshold-type shifts occur. We identify systems and drivers that could lead to self-sustaining feedbacks, abrupt changes, and some degree of resilience, as opposed to binary states not subject to self-propelling changes or resilience. Changes driven by warming, browning, and eutrophication can cause increased lake stratification, heterotrophy (browning), and phytoplankton or macrophyte mass (eutrophication), which separately or collectively drive benthic oxygen depletion and internal phosphorus loading and in turn increase greenhouse gas (GHG) emissions. Several of these processes can feature potential tipping point thresholds, which further warming will likely make easier to surpass. We argue that the full importance of the vulnerability of lakes to climate and other anthropogenic impacts, as well as their feedback to climate, is not yet fully acknowledged, so there is a need both for science and communication in this regard.
Extracting Spatiotemporal Flood Information from News Texts Using Machine Learning for a National Dataset in China

Published: May 2024

Abstract. Urban floods present a threat in China, demanding an understanding of their spatiotemporal distribution. Current flood datasets primarily offer provincial-scale insights and lack temporal continuity, which leads to a challenge in detailed analysis. To create a consistent national dataset of flood events, this study introduces a machine learning framework by applying online news media as a primary data source to construct a county-level dataset of urban flood events from 2000 to 2022. Using the Bidirectional Encoder Representations from Transformers (BERT) model, we achieved robust performance in information extraction, with an F1 score of 0.86 and an exact match score of 0.82. Further, a combined model of Bidirectional Long Short-term Memory (BiLSTM) networks with a Conditional Random Field (CRF) layer effectively identified flood locations. Our analysis reveals that the temporal trend of flooded cities in the news-based dataset is similar to the China Flood and Drought Bulletin. Furthermore, the consistency of flood events in the news with the typhoon trajectory in two cases, and the connection between flood occurrences and flood conditioning factors, confirm the accuracy of spatial distribution. The validated news-based dataset analyzes urban floods in China from both temporal and spatial perspectives. First, this dataset shows the seasonal characteristics of flood events, which are concentrated in the summer. From 2000 to 2022, the peak year for floods was 2010, and excluding the influence of peak year, the overall temporal trend of total flood occurrence shows an increase. Spatially, the distribution of floods decreases from southeast to northwest, with Guangxi Province having the highest number of floods. Additionally, the Yangtze and Pearl River basins are most frequently affected by urban floods. The subtropical climate zone is the most susceptible to flooding. This study provides an automated and effective method for constructing a national flood event dataset and reveals the spatiotemporal characteristics of urban flooding in China.

Investigating the role of Neuropilin-1 in claudin-low breast cancer
Authors:   , Tang Thomas
Published: May 2024

Triple-negative breast cancers (TNBC) have a relatively poor prognosis and responses to targeted therapies. Between 25% and 39% of TNBCs are claudin-low, a poorly differentiated subtype enriched for mesenchymal, stem cell and mitogen-activated signalling pathways. This thesis investigated the role of the cell surface co-receptor Neuropilin-1 (NRP1) in the biology of claudin-low TNBC. The data generated implicated NRP1 in the oncogenesis and progression of claudin-low breast cancer and provided pre-clinical support for the efficacy of NRP1 inhibition as a targeted therapy for claudin-low tumours.
Missions Abyssines. L’Etiopia, la Grande guerra e la Conferenza della pace
Authors: Zaccaria Massimo
Published: May 2024

Nella storia della Prima guerra mondiale, e poi in quella della Conferenza della pace di Parigi, l’Africa non ha quasi spazio e a stento vi sarebbe entrata se non fosse stato per le operazioni del generale Paul Emil von Lettow-Vorbeck e delle sue truppe nell’Africa orientale. Attraverso il caso di tre delegazioni che, nella primavera del 1919, il governo etiopico inviò in Europa e negli Stati Uniti, questo volume offre una nuova interpretazione dell’impatto della Grande guerra sull’Etiopia e sui paesi vicini. Sulla base di un’ampia documentazione d’archivio e iconografica, l’autore ricostruisce la vicenda di queste tre missioni inserendola nel contesto storico, ne ripercorre le tappe e si interroga sui suoi veri obiettivi. Ne emerge l’immagine di un paese determinato a salvaguardare a ogni costo la propria indipendenza e deciso a rispondere colpo su colpo alle manovre dell’Italia che, a partire dal 1917, aveva cominciato a premere per ridefinire gli equilibri politici del Corno d’Africa con l’obiettivo di porre l’Etiopia sotto il suo esclusivo controllo.
Urban Piety & Camino de Santiago: Impact of Medieval Cities on Pilgrimage Devotion
Authors: Roszak Piotr , Mróz Franciszek , Chodkowska-Miszczuk Justyna
Published: May 2024

Pilgrims traveling to Santiago carried with them new forms of saint worship observed along the way, while also maintaining their religious customs from their hometowns. During the Middle Ages, it was often urban dwellers who embarked on these pilgrimages. En route to Compostela, they found support in the cities they passed through, receiving hospital care and accommodations, and participating in city life, particularly during festivities. However, they also faced challenges such as dishonesty, exploitation, and temptation. Additionally, they encountered a distinct urban piety associated with brotherhoods and religious formations, which influenced their approach to pilgrimage. In the paper, while examining the life of medieval cities and their devotional practices, as well as the material evidence of pilgrim presence such as badges, I will explore how this urban experience shaped the mentality of pilgrims. Furthermore, I will investigate the role of cities in the development of the pilgrimage movement to Compostela, with a focus on Toruń and Gdańsk
Czego nie wiemy o filozofii średniowiecznej?
Authors:   Katedra Historii Filozofii Starożytnej i Średniowiecznej, Wydział Filozofii, KUL JP II, Kijewska Agnieszka
Published: May 2024

Prezentowany tom zawiera eseje Agnieszki Kijewskiej poświęcone dziejom filozofii średniowiecznej, publikowane w latach 2021–2023 na portalu „Filozofuj”. Zadaniem tego przedsięwzięcia było rzucenie nowego światła na ten okres w dziejach ludzkiej myśli, który – pomimo ogromnego postępu badań – w świadomości potocznej wciąż jawi się w niezbyt korzystnym świetle. Z tego właśnie względu autorka starała się wytropić starożytne źródła myśli wieków średnich oraz pokazać, jak ta myśl wciąż żyje i ma znaczenie dla kultury współczesnej. W tym celu starała się odejść od uznanych paradygmatów uprawiania filozoficznej mediewistyki, czyli od tego, co „wiemy” o filozofii średniowiecznej, i przedstawić ją z nieco innego, mniej standardowego punktu widzenia, tytułując cały tom: Czego nie wiemy o filozofii średniowiecznej. Na pierwszy plan wydobyła najbardziej charakterystyczne metafory obecne u autorów wieków średnich, jak np. koncepcja człowieka jako mikrokosmosu. Takie podejście powoduje, że w sposób naturalny więcej uwagi poświęca tym autorom, którzy lokują się w obrębie szeroko rozumianej tradycji platońskiej, obalając tym samym schemat mówiący o dominacji arystotelizmu w średniowieczu. Do tej kwestii nawiąże jeszcze w dalszych tekstach, bo zebrane w tym tomie eseje, choć nie są zamierzone w układzie chronologicznym, obejmują zasadniczo myślicieli do XII wieku włącznie, sporadycznie odwołując się do innych autorów. Nawiązanie do koncepcji Pierre’a Hadota filozofii jako ćwiczenia duchowego pozwala autorce w tym właśnie kluczu ująć przebogatą tradycję myśli wieków średnich i skoncentrować się przy tym na tych tekstach i autorach, którzy należą do mniej znanych. Autorka chciałaby przekonać czytelnika o wartości i pięknie tych tekstów i o ich niezmiennej aktualności. W książce starała się przestrzegać zasad warsztatu naukowego historyka filozofii, nie obciążając zbytnio potencjalnego czytelnika różnymi technicznymi kwestiami, ale dając mu możliwość i zachętę do samodzielnego sięgnięcia do źródeł.
Good faith in employment relations – between standard and duty
Authors: Donos Evlampie
Published: May 2024

The current Labour Code of the Republic of Moldova does not regulate the principle of exercising constitutional rights and freedoms in good faith. Exercising of these rights is complemented by the other dispositions contained in the labour legislation and, insofar as they are not incompatible with the specifics of the labour relations provided by the code in question, with the provisions of civil legislation. The civil legislation in the matter of good faith stipulates that this institution is a standard of conduct of a party, characterized by fairness, honesty, openness and taking into account the interests of the other party to the legal relationship. In the sense of the invoked principle, it is assumed that an employee exercising his rights at work fairly and honestly, must take into account the employer’s interests. However, in terms of the content of the legal employment relationship, the interests of the parties differ. The purpose of this paper is to analyse some aspects regarding the implications of the principle of good faith in the execution of employment contracts, a principle which is valid for the parties to employment contracts.
A STUDY OF THE SINTERING PROCESS WITH GASEOUS FUEL INJECTION INTO THE SINTERED LAYER
Authors: Шаповалов А.Н. , Фукс А.Ю.
Published: May 2024

Приведены результаты лабораторных экспериментов по исследованию влияния расхода газообразного топлива (природного газа), подаваемого в слой спекаемой шихты, на показатели аглопроцесса и качество агломерата в шихтовых условиях АО «Уральская Сталь» при высоте слоя шихты от 350 до 500 мм. Установлено, что увеличение расхода природного газа, подаваемого в слой спекаемой шихты в диапазоне от 3 до 7 м3/т спека, способствует повышению вертикальной скорости спекания, выхода годного, удельной производительности и прочностных свойств агломерата. Положительное влияние подачи в слой газообразного топлива объясняется улучшением температурно-временны΄х условий спекания, что увеличивает степень вовлечения рудной части шихты в процессы расплавообразования, а также обеспечивает более полное использование твердого топлива при меньшем его расходе. Эффективность подачи газообразного топлива в слой спекаемой шихты существенно повышается с увеличением высоты спекаемого слоя, что обусловлено уменьшением доли верхней части спека, формирующейся в менее благоприятных тепловых условиях. По совокупности показателей, с учетом стоимости природного газа, его оптимальный расход в шихтовых условиях работы АО «Уральская Сталь» составляет 3,0 м3/т спека, при котором обеспечиваются максимальный прирост показателей спекания и качества агломерата в сравнении с традиционной технологией агломерации.

The results of laboratory experiments to study the effect of natural gas injection into the sintered layer on sintering process indicators and sinter quality in the charge conditions of JSC «Ural Steel» at a layer height of 350 to 500 mm are presented. Based on the results obtained, it was found that an increase in the consumption of natural gas from 3 to 7 m3/t of sinter provides an increase in the vertical rate of sintering, yield, specific productivity and strength properties of sinter. The positive effect of injecting gaseous fuel into the sintered layer is due to improved temperature-time conditions of sintering, which increases the degree of involvement of the ore part in the processes of melt formation, as well as provides a more complete use of solid fuel at a lower consumption of fuel. The efficiency of injection of gaseous fuel into the sintered layer increases significantly with increasing sintered layer height, which is due to the reduction of the proportion of the upper layer of sinter formed in less favorable thermal conditions. According to the totality of indicators, taking into account the cost of natural gas, its optimal consumption in the charge conditions of JSC “Ural Steel” is 3.0 m3/t sinter, which provides the maximum increase in sintering parameters and sinter quality in comparison with the traditional technology of sintering.

Исследованы закономерности совместного влияния химического состава и параметров глобулярно-пластинчатой структуры на механические свойства катаных прутков из сплава ВТ6 после отжига по различным режимам. На основе корреляционного анализа было установлено, что колебания марочного состава в перерасчете на эквиваленты по алюминию и молибдену оказывают более значимое влияние на механические свойства по сравнению со структурным фактором. Разработана модель для прогнозирования предела прочности отожженных прутков диам. 15–90 мм с учетом химического состава и параметров глобулярно-пластинчатой структуры.

The regularities of the joint influence of the chemical composition and parameters of the globular-lamellar structure on the mechanical properties of rolled bars of the VT6 alloy after annealing in various modes are studied. Based on the correlation analysis, it was found that fluctuations in grade composition in terms of aluminum and molybdenum equivalents have a more significant effect on mechanical properties compared to the structural factor. A model has been developed for predicting the ultimate strength of annealed bars with a diameter of 15–90 mm, taking into account the chemical composition and parameters of the globular-lamellar structure.

Introdução: As infecções sexualmente transmissíveis (IST) se espalham predominantemente por contato sexual sem proteção, podendo também haver transmissão de forma vertical (mãe para filho) e por objetos contaminados. Percebe-se que na atualidade há uma relativa falta de progresso de parar a propagação de IST no mundo, gerando um impacto profundo na saúde populacional, levando a efeitos graves e crônicos. Sendo assim, são imperantes e necessárias ações de educação em saúde para a prevenção de IST. Objetivo: Relatar a experiência de ações de educação em saúde como estratégia de prevenção de IST em escolas públicas de ensino médio em Maceió, Alagoas. Métodos: Trata-se de um relato de experiência sobre as ações de educação em saúde sobre IST realizadas pelo projeto de extensão “Quem Ama Cuida”, vinculado à Universidade Federal de Alagoas, desenvolvidas por um grupo multidisciplinar de discentes e docentes da área da saúde. Resultados: A partir das vivências, percebeu-se que a educação em saúde tem extrema importância na prevenção da temática pelo seu alto poder transformativo. Isso porque, por meio das ações, gera-se conhecimento das principais IST e suas formas de prevenção, mediante palestras expositivas dialogadas; incentiva-se a busca pela vacinação, pela testagem rápida e por serviços de saúde caso apresente sintomas, visando assim a promoção em saúde. Pontuam-se também benefícios aos discentes vinculados ao projeto, conscientizando o acadêmico da importância não só das ações curativas, mas também das preventivas. Além de desenvolver aptidões importantes para os ambientes profissionais e pessoais, como o desenvolvimento das habilidades de liderança, construção colaborativa, escuta qualificada, oratória e didática. Conclusão: Compreende-se que ações de extensão de educação em saúde se fazem eficazes e necessárias na prevenção das IST, modificando comportamentos e práticas, ajudando os indivíduos a se reconhecerem como agentes responsáveis pela promoção de sua saúde e oferecendo oportunidades de crescimento pessoal e profissional para os extensionistas.

Speaking with the Dead
Authors: Tomlinson Matt
Published: May 2024

If you tried speaking with a dead person and they gave you a clear response, how would you react? Mediums develop their minds and bodies to communicate messages from the deceased to their living loved ones, and in Speaking with the Dead, anthropologist Matt Tomlinson describes his experiences training as a medium with a Spiritualist congregation in Canberra, Australia. The book is written in a first-person narrative style that brings “extrahuman” relationships to life, showing what it is like to learn and practice mediumship: the strategic suspension of skepticism; the wobbly first attempts; the embarrassing failures; and the moments, both unsettling and enthralling, when someone tells you that yes indeed, you’ve just described her grandfather who died in 1978.

Speaking with the Dead brims with stories of talented mediums and Tomlinson is not interested in proving or disproving mediumship, preferring instead to illustrate how mediums bring their practices to life. In contrast to the popular image of mediums as shameless frauds, Tomlinson describes earnest and committed seekers from a wide range of backgrounds who often struggle to understand their own experiences. Their profits are therapeutic rather than financial. And they worry about endings as much as anyone else: the passing of physical lives, the closure of beloved churches. Speaking with the Dead is ultimately a book about the lively side of death, grounded in Spiritualists’ conviction that life is eternal and your social network extends to the astral plane. It is a close examination of how mediumship works culturally, which is to say, how mediums and audiences work together to create senses of transcendent connection.
Clinical Affordances: Towards an Ecological Account of Health Affordance and Design of Clinical Learning Spaces
Authors: Schweitzer Daniel R , Laakso E-Liisa , Ting Joseph , Brymer Eric
Published: May 2024

In this article, we address the following question: how should clinical environments be designed to promote learning opportunities for clinicians? We develop an ecologically-informed account of learning opportunities informed by Gibson’s influential ecological theory of perception (Gibson, 1977, 1979). The so-called ‘push-pull’ account is proposed as a framework in which we can conceptualise how affordances are formed and actioned across different areas of clinical practice. We develop an account of health-care-related affordances that is discussed in relation to surgical training with a particular emphasis in terms of how skills are acquired in the use of robotic surgical techniques. Our primary focus is on the performative aspects of surgical performative process. We situate the current discussion in relation to a broader discussion about skills development in the context of healthcare as well as the future design of clinical spaces.

Transformer-Less Grid-Connected Photovoltaic Inverter
Authors: Rohit Repalle , Kishor Gudipati
Published: May 2024

The increasing use of inverters in microgrids and Photovoltaic generation systems has made it more crucial than ever to achieve low-distortion, high-quality power export from inverters. The presence of harmonics in the grid's pre-existing voltage/current distortion will result in poor power quality. A well-designed inverter impacts minimizing the percentage of total harmonic distortion (THD) in the power supplied to the grid. This paper proposes H6 inverter topology in comparison with conventional H4(Full-bridge) topology to reduce the grid disturbance in the context of THD and maintain good waveform quality. The Transformer-less Single-Phase Grid-Connected photovoltaic inverter using MATLAB/Simulation is implemented. The depreciation of %THD and improvement in the power factor in the proposed system emphasize its prominence in practical implementation.
Construcción identitaria en África subsahariana: reflexiones sobre los sesgos de la implementación del modelo cívico-político de nación en Costa de Marfil
Authors: Flan Goualo
Published: May 2024

El estudio analiza, desde el caso marfileño, los sesgos de la implementación del modelo cívico-político de nación en la construcción identitaria en África subsahariana. Se apoya en el método de estudios de caso, sustentado en la investigación documental y la entrevista en profundidad para la recolección de datos, así como la inducción analítica y el análisis del discurso para el análisis de datos. Los resultados develan que, si las dimensiones inclusiva e integradora de la identidad construida desde la marfilidad cultural entre 1974 y 1994 resultaron poco cuestionables, las modalidades de inclusión e integración presentaron por su parte sesgos considerables.

Authors: Trương Thị Bích Hồng
Published: May 2024

Họ trùn chỉ gồm những loài có kích thước nhỏ, thành cơ thể mỏng dài khoảng 20-25mm, có đầu hình nón đơn giản và thân hình trụ có nhiều đốt (55-95) như: Tubifex tubifex, Limnodrilus hoffmeisteri, Branchiura sowerbyi. Bài báo này cung cấp các hình thức nuôi sinh khối trùn chỉ là thức ăn sống cho động vật thủy sản. Bởi vì, trùn chỉ đóng vai trò quan trọng ở cả hệ sinh thái tự nhiên và  trong sản xuất giống thủy sản. Ngoài tự nhiên, trùn chỉ phân bố trong rãnh nước thải, ao, hồ nước ngọt với mật độ cao. Thức ăn của trùn chỉ chủ yếu là các các hạt khoáng vô cơ và hữu cơ ở nền đáy của thủy vực. Trùn chỉ ăn liên tục, trùn trưởng thành có khả năng tiêu hóa một lượng lớn thức ăn (32% khối lượng cơ thể) trong một ngày [21]. Do đó, trùn chỉ không chỉ là thức ăn ưa thích cho các loài cá động vật đáy mà còn thúc đẩy nhanh quá trình phân giải trầm tích đáy. Trong nuôi trồng thủy sản, trùn chỉ được nuôi thu sinh khối làm thức ăn cho giai đoạn cá bột của nhiều loài thủy đặc sản ở nước ngọt như (lươn, trê phú quốc,...) và cá cảnh. Vì, trùn chỉ có năng lượng và giá trị dinh dưỡng cao. Năng lượng của nhóm L. hoffmeisteri, T. tubifex phân bố ở vùng nước lợ đạt 5575 cal/g khối lượng khô [11]. Thành phần dinh dưỡng của loài T. tubifex chứa protein 57% protein, 13,3% chất béo, chỉ có 2,04%  chất xơ, 3,6% tro [24].

Sơ chế phụ phẩm rong nho (Caulerpa lentilliera) làm nguồn nguyên liệu để sản xuất rong nho cháy tỏi đã được nghiên cứu. Kết quả cho thấy, phụ phẩm rong nho sau khi phân loại, làm sạch được ngâm trong nước ngọt ở nhiệt độ phòng (26 ± 1ºC) trong thời gian 30 phút giúp loại bỏ tối đa mùi tanh và muối trong rong. Rong nho được chần ở nhiệt độ 85ºC trong thời gian 15 giây giúp rong giữ được màu xanh tốt nhất. Điều kiện ly tâm 800 vòng/phút trong 8 phút tách được 24% lượng nước bám trên bề mặt nhưng vẫn giữ được cấu trúc của rong. Sấy lạnh kết hợp bơm nhiệt ở 55ºC trong thời gian 3 giờ (vận tốc không khí 2 m/s, bề dày của lớp rong 0,5 ± 0,2 cm), thu được phụ phẩm rong nho khô có độ ẩm 4% và hoạt độ nước 0,52. Kết quả đạt được từ nguyên cứu này chỉ ra tiềm năng sử dụng phụ phẩm rong nho đã sơ chế như một nguồn nguyên liệu để sản xuất rong nho cháy tỏi.

Governance mechanisms for Municipal Solid Waste (MSW) are critical to the sustainable management of waste for effective environmental management and public health. These mechanisms are dependent on management frameworks upon which they are based. This study aimed at assessing current frameworks for managing MSW in Zambia using a descriptive research design with a questionnaire being the data collection tool. Eighty purposively sampled respondents were administered and the tool had a 90 per cent response rate. Data analysis involved the use of frequency tables, percentages, bar, the mean, and standard deviation. The results were as follows; male respondents were 73 per cent as compared to female respondents at 27 per cent, respectively, while source of generation for residential areas was at 88 per cent. Public sector role in the governance of MWS 66.7 per cent, private sector (18.9%), NGOs (7.8%), with academia 2.2 per cent, others 4.4 per cent respectively. Frequency of collection was as follows: daily (45.7%), twice a week (14.9%), weekly (39.4%). Recycling of MSW by the private sector (47.2%), municipality (14.6%), and a combination of both accounted for 38.2 per cent. Management of final disposal sites by private sector (11.7%), municipalities (44.6%) and co-managed sites (43.5%). Lack of technical capacity to develop and implement policies by municipalities was 33 per cent while lack of financial resources for the waste management sector (39%). The results of the study indicate a growing and rooted challenge in the governance of MSW in Zambia. Therefore, governance mechanisms must be based on robust and effective frameworks that will ensure effective service delivery by local authorities with the involvement of all stakeholders, gender and social inclusion and also effective development and application of policies, technology and financial resources. This will result into sustainable waste management service to protect public health and the environment and ultimately implement a circular economy model.

W zakresie obowiązków straży pożarnej są m.in. działania operacyjne związane ze zdarzeniami radiacyjnymi, w tym polegające na: identyfikacji źródła zagrożenia, ratowaniu ludzi, zwierząt i mienia, zabezpieczeniu terenu i wstępnej dekontaminacji skażonego terenu. Podczas wykonywania tych czynności konieczne jest stosowanie środków ochrony indywidualnej, które mają zapewnić wysoki stopień bezpieczeństwa strażakom. Takie środki mogą być wielokrotnie narażone na oddziaływanie szkodliwego promieniowania jonizującego i innych szkodliwych związków chemicznych związanych z zaistniałym zdarzeniem. Działanie promieniowania jonizującego na materiały polimerowe i tekstylne wywołuje pierwotne i wtórne procesy fizykochemiczne, prowadzące do nieodwracalnych zmian chemicznych, które mogą wpływać na właściwości ochronne tych materiałów. Dlatego z punktu widzenia bezpieczeństwa pracowników straży pożarnej istotne jest ustalenie wpływu promieniowania i procedur związanych z dekontaminacją na zachowanie skuteczności działania środków ochrony indywidualnej. Słowa kluczowe: promieniowanie jonizujące, zdarzenie radiacyjne, środki ochrony indywidualnej
