Authors: Pérez-González Rebeca , Sòria-Perpinyà Xavier , Soria Juan , Sendra Maria D. , Vicente Eduardo
Published: July 2023

One of the main problems arising in inland waterbodies is nutrient enrichment that accelerates eutrophication, causing massive cyanobacteria blooms and degrading aquatic ecosystems. This study focused on physical/chemical factors that affect cyanobacteria of 30 reservoirs in the Ebro River basin within the Iberian Peninsula of northeastern Spain. The abundance of cyanobacteria was assessed as total cell number, total biovolume, and the indicator pigment, total phycocyanin (PC). In addition, empirical measurements for PC were compared to PC estimated from remote sensing. Variables assessed for correlation with cyanobacteria abundance included temperature, pH, light availability inferred from Secchi depth, water residence time, total nitrogen, dissolved inorganic nitrogen, total phosphorus, soluble reactive phosphorus, silica, and total phytoplankton biomass as chlorophyll a. These variables were also assessed with a multi-statistical principal component analysis for relationships with cyanobacteria abundance. Cyanobacteria cell number and biovolume were positively correlated with temperature, total nitrogen, total phosphorus, and water residence time, and negatively correlated with silica. High PC concentrations were documented in the reservoirs, and satellite images from remote sensing showed the PC spatial distribution and heterogeneity in the reservoirs. The PCA results show that some variables, such as nitrogen and phosphorus, are closely related to the abundance of cyanobacteria, while other variables such as silica do not show a clear relationship. This study contributes to the knowledge base about inland waterbodies from a physical/chemical perspective, which had not been done before in the Ebro Basin, including the application of analytic tools such as remote sensing.

Published: July 2023

Vegetation plays a vital role in the flow characteristics of natural open channels, such as rivers. Typically, vegetation density is higher in the lower layer and sparser in the upper layer of these channels. In this research, Ansys Fluent and the k–ϵ model have been employed to simulate various vegetation configurations to capture intricate flow complexities within vegetation regions. Numerical analysis demonstrated that the numerical results align with anticipated Turbulence Kinetic Energy data obtained from analytical and experimental studies. Our findings revealed that double-layer vegetation induces a more intricate flow distribution. In the spaces between vegetation zones, Turbulence Kinetic Energy decreases due to the resistance imposed by the vegetation patches. This resistance has positive implications for sustaining aquatic life and facilitating sediment deposition, promoting a more environmentally sustainable outcome.
Utopian River Planning and Hydrosocial Territory Transformations in Colombia and Spain
Authors: Duarte-Abadía Bibiana
Published: July 2023

This paper examines how utopian river planning has arisen in Colombia and Spain since the late nineteenth century. Specifically, the paper contributes to understanding how particular ideologies of modernism and development present in territorial planning connect both countries. Taking Thomas More’s classic work ‘Utopia’ as the analytical reference, I analyze how utopian tendencies have traveled through time and space to shape territorial planning and water governance. In both countries, this was evident in the late nineteenth century through the political project to strengthen the nation state. For Spain, I describe the regenerationist movement and the hydraulic utopia led by the Spanish intellectual Joaquín Costa, who forged the dream of a water nationhood. By contrast, in Colombia, several political intellectuals looked at Europe and North America as a source of inspiration to achieve progress by controlling rivers. Through the method of disjunctive comparison, I show how the same utopian notions are expressed in similar ways in distinct contexts: violently governing the flows of rivers, standardizing minds and ordering territories towards capital growth. This paper contributes to grasping the notions and roots of the discourses that have colonized the political water agendas in both countries.

The Plushykha River is one of the nine small urban rivers of Novosibirsk feeding the Ob. In its coastal zone there are garden societies, highways, railways, which have a significant impact on its condition. The purpose of this work was to assess the state of the coastal zone and some hydrochemical and physical indicators of the water of the Plyushchikha River within the city of Novosibirsk. According to the results of the observations, erosion of coastal slopes by thawed and stormwater was noted, siltation of the Ivy riverbed is observed in the summer. When studying the physical parameters of water, an increase in the intensity of odor in the spring, summer and winter period was noted to 3.0; 4.8 and 2.8 points, respectively. The color index in winter and spring is 44°, which is 2 times higher than the MPC, in summer — 54°, which is 2.7 times higher than the MPC. There was also an excess of the permissible turbidity value in the spring period by 2.6 times, and in the summer and winter periods by 3.6 times. The pH of the water in summer and winter is slightly alkaline, and in spring it is alkaline (9.0 units), the hardness of the water of the Plushykha River varies depending on the season. In spring, this indicator was 4.62°F, in summer — 5.32°F, and in winter — 10.56°F, which is slightly higher than the MPC (10.0°F). The total alkalinity of the water was 9.5 mg*eq/l in spring, 7.5 mg*eq/l in summer, and 12.54 mg*eq/l in winter, with a norm of up to 7.9 mg*eq/l. The concentration of nitrates in the spring and summer periods exceeded the maximum permissible value for natural reservoirs (0.2–1 mg/l) and amounted to 10.0 and 12.3 mg/l, respectively. The level of nitrite ions in river water in spring and summer was 0.7; 0.4 mg/l at MPC — 0.2 mg/l.

Published: July 2023

Manusia menghasilkan emisi karbon dioksida (CO2) dari penggunaan energi dalam aktivitasnya sehari-hari. Semakin banyak aktivitas manusia, maka semakin banyak energi yang digunakan, sehingga semakin besar pula carbon footprint yang dihasilkan oleh manusia tersebut. Metoda perhitungan carbon footprint adalah suatu metoda untuk mengukur aktivitas manusia yang menimbulkan dampak terhadap lingkungan, melalui perhitungan berapa banyak by-product (Gas Rumah Kaca, GRK) yang dihasilkan, biasanya dihitung dalam ukuran unit CO2. Analisis perhitungan carbon footprint ini merupakan hasil survey data dasar untuk pembuatan aplikasi “Carbon Footprint Calculator.”  Sampel survey ini adalah rumah masyarakat di wilayah kerja Puskesmas Pasirkaliki. Sampel diambil secara purposive sampling di Kampung Rancabali RW 3 Kelurahan Pasirkaliki Cimahi Utara. Survey penggunaan gas, bensin, dan listrik rumah tangga dikumpulkan menggunakan Instrumen Pengumpul Data (IPD). Hasil survey menunjukkan rata-rata emisi CO2 primer yang dihasilkan dari kegiatan penggunaan gas LPG menghasilkan 0,007 ton CO2/rumah/bulan, sedangkan penggunaan bahan bakar bensin yaitu 0,073 ton CO2/rumah/bulan. Hasil perhitungan emisi sekunder konsumsi energi listrik menunjukkan rata-rata emisi 0,102 ton CO2/rumah/bulan. Masyarakat hendaknya melakukan penghematan dalam penggunaan energi pada kegiatan rumah tangga, selain itu masyakat disarankan untuk mulai melakukan penanaman tanaman di masing-masing rumah sebagai bentuk upaya mengurangi emisi karbon (CO2). Hal ini dilakukan karena tanaman atau pohon dapat menyerap emisi karbon (CO2) yang dihasilkan.
Ecological significance and conservation priorities of Europa Island (western Indian Ocean), with special reference to seabirds
Authors: Le Corre Matthieu , Jouventin Pierre
Published: July 2023

Située dans le sud du canal de Mozambique, l’île Europa est l’une des îles les moins connues de la région malgache. Nous avons réalisé six séjours dans l’île, de 1993 à 1996, afin d’évaluer l’état des écosystèmes terrestres, de recenser les populations nicheuses d’oiseaux de mer et d’identifier les facteurs susceptibles de réduire la biodiversité de l’île. Les résultats obtenus montrent que l’île Europa est une des îles les moins perturbées de l’océan Indien occidental.

Les différentes tentatives d’occupation humaine ayant eu lieu depuis la fin du XIXe siècle sont probablement à l’origine de l’introduction de plusieurs espèces de plantes et d’animaux. De plus, la réalisation au début du XXe siècle d’une culture de sisal (Agave sisalina et Furcraea foetida) a provoqué la disparition d’une partie de la forêt sèche indigène (10 %). Cependant, la plus grande partie de l’île n’a pas subi de perturbations importantes depuis les premières installations humaines et la végétation actuelle est, dans ces endroits, probablement proche de son état originel. De ce fait, la faune des vertébrés est riche (7 espèces de reptiles et 13 espèces d’oiseaux dont 8 espèces d’oiseaux de mer). Les populations d’oiseaux de mer sont plus grandes que ce qui était estimé précédemment, en particulier celles des grands Pélécaniformes (Paille-en-queue à brins rouges Phaethon rubricauda, Fou à pieds rouges Sula sula, Frégate du Pacifique Fregata minor et Frégate ariel F. ariel ) et celle de la Sterne Fuligineuse (Sterna fuscata). Deux autres espèces, le Puffin d’Audubon (Puffinus Iherminieri) et le Paille-en-queue à brins blancs (Phaethon lepturus) ont un intérêt biogéographique remarquable. La principale menace identifiée est la prédation des œufs et poussins d’oiseaux de mer par le Rat noir (Rattus rattus), introduit. L’impact du Corbeau pie (Corvus albus), espèce anthropophile, et de la Chouette effraie (Tyto alba) comme prédateurs d’oiseaux de mer est discuté. Trois autres sources de risques potentiels de modification de l’habitat, en particulier de la forêt sèche, ont été identifiées : le surpâturage par les chèvres, les incendies naturels ou accidentels et l’invasion du milieu par le sisal.

Nous proposons un programme de conservation pour éviter la perte de biodiversité. La première étape, actuellement en cours, consiste à quantifier les menaces. La seconde étape sera de restaurer l’île dans son ensemble, par le contrôle ou l’éradication des espèces animales ou végétales introduites pouvant mettre en danger les écosystèmes terrestres indigènes.

Published: July 2023

At the beginning of COVID-19 pandemic, highly accurate information about the clinical manifestations of the disease was not available, and the reported symptoms were non-specific and more related to respiratory symptoms such as fever, dry cough, fatigue, and sputum production. As time has passed, skin manifestations have been proposed as one of the clinical manifestations of COVID-19 in some patients. Among all reported lesions, livedoid lesions appeared simultaneously with the symptoms of SARS-CoV-2, mainly in elderly people with severe infections, and were associated with the highest risk of the mortality of all skin lesions. Knowledge of the skin manifestations that may be the only symptoms of COVID-19 may help in early diagnosis and specific treatment. In the current review, the skin findings of patients in association with COVID-19 were summarized into the categories of maculopapular or morbilliform lesions, urticarial lesions, chilblain-like lesions, vesicular lesions, petechiae or purpura lesions, and livedoid lesions.

Identification of the Leading Economic Sectors of Nigeria: A Typology Juxtapose of Nigerian Economy Vis-À-Vis African Economies
Authors: Sadiq M.S. , Singh I. P. , M. Ahmad M. , M. A. Isah
Published: July 2023

Objectives: The typology of Nigeria's economy was examined alongside those of West Africa, sub-Saharan Africa, and developing economies in Africa using time-series data from 1970 to 2018. Some issues remain and will continue to attract the attention of academics, activists, members of civil society, and practitioners to answer the question if Nigeria is capable of realizing its vast potential and maintaining its ability to grow.

 Methods: The data covered the values of nine sectors, each in the economy at constant prices, and the data were analyzed using inferential statistics.

Results: Empirical evidence has shown that crude oil and solid minerals are the main core sectors of the Nigerian economy at the subregional level before Nigeria's economy shifts to agriculture and sectors of the third production chain, possibly the likely cause of Africa's emerging oil economies. Furthermore, concerning regional economies, agriculture and related activities, and the third sector of Nigeria's economy, it has the potential to grow faster. The possible reasons for this are that they are long-term sustainable, appropriate, and reliable alternative sources of revenue earning due to the global collapse in oil prices and insurgencies affecting the Nigerian economy's mineral resources and secondary production sectors. Besides, the secondary production chain needs to be strengthened to become potential, thus complementing the non-oil sectors of the Nigerian economy.

Conclusions: For the well-being of Nigerians, the surest means is for policymakers to adhere to the optimal potential development of agriculture and related activities and the high-production sectors of the country's economy. To sustain the Nigerian economy, it must be diversified non-oil supported by agriculture and the allied sector because the appropriate way to strengthen the country's economy is to harness the economic activities that form the basis of the economic life of Nigerians and will be able to absorb the current human resources conditions.

Diante disso, os/as professores/as do nível I, alfabetização e nível II, sistematização da Escola Municipal José do Patrocínio, Natal, Rio Grande do Norte, elaboraram o projeto pedagógico, intitulado “O ensino remoto na educação de jovens e adultos (EJA): a efetivação do direito à educação e à saúde dos/as alunos/as e professores/as em tempo de Pandemia (Covid-19)”, com o objetivo de efetivar os Direitos Sociais – Direito à Educação dos jovens, adultos e idosos, matriculados na EJA. As atividades desenvolvidas contemplaram: aulas síncronas (remotas), fórum de debates, plantão de dúvidas e atividades avaliativas realizadas por meio das plataformas como Google Meet e Whatsapp. Paralelamente ao projeto pedagógico em comento, realizamos uma pesquisa qualitativa em educação (LUDKE; ANDRÉ, 1995; BOGDAN; BIKLEN, 2012). Os instrumentos de coleta de dados foram: observação participante; gravação das aulas, posteriormente, transcritas; diário de campo; pesquisa documental; e análise de conteúdo. Os resultados desse trabalho foram organizados e apresentados à coordenação pedagógica sob forma de relatório e, posteriormente, em artigo científico, ora apresentado com o objetivo de socializar as análises e conclusões sobre a efetivação do Direito à Educação de jovens, adultos e idosos no período de pandemia (Covid-19). Diante dos resultados, inferimos que o desenvolvimento das atividades pedagógicas desenvolvidas durante o período de pandemia (junho a dezembro/2020) promoveu: a inclusão digital de jovens, adultos e idosos matriculados na EJA, nível I, alfabetização e nível II, sistematização; possibilitou aos alunos/as e professores/as superar desafios de ordem pedagógicas e institucional; construir e reconstruir saberes. Por fim, efetivou o Direito à Educação de jovens, adultos e idosos, já tão desrespeitado ao longo da vida, consequentemente, promoveu a formação social e educacional dos/as alunos/as e professores/as.

A transição imediata do ensino presencial para o remoto, imposta pelo isolamento social decorrente da pandemia do vírus SARS-CoV-2, desafiou ainda mais as modalidades de ensino da educação brasileira, em especial a Educação de Jovens e Adultos (EJA), que exige uma interação, diálogo e troca de experiências entre docente e discentes. A partir dos mais variados desafios, o artigo aborda os efeitos da crise sanitária, na vida dos estudantes trabalhadores, no processo de ensino e na aprendizagem na modalidade EJA na Escola Estadual Deputado Fernando Cláudio Capiberibe Saldanha, em Ponta Porã/MS. Através de uma pesquisa bibliográfica e qualitativa, os resultados evidenciaram que o acesso à tecnologia de informação, o letramento digital e a necessidade do auxílio do professor estão entre os principais desafios. Em Ponta Porã, tanto docentes como discentes deixaram evidente a necessidade da experiência presencial para construção do conhecimento.
On the Relationship Between ISO Standards and Sustainable Development

Published: July 2023

The survival of humans and other organisms requires healthy ecosystems and environments. Towards the sustainability path, a social challenge, entailing international and national law, urban planning and transport, supply chain management local and individual lifestyles, and ethical consumerism is needed. International Standards Organization is working on matching SD Goals with ISO standards. The main goal of conducting this research was to clarify the relations between sustainable development and quality management. This was done by handling a regression analysis between the Sustainable development goals Index and ISO Standards Index to verify Hypothesis H1 (There is not any relation between SDG Index and ISO 9001 Index) against Hypothesis H0 (There is a strong relation between SDG Index and ISO 9001 Index). The results of the research are that scientific management of factors of production creates opportunities for long-term sustainable development, guaranteeing future generations’ normal life and society’s wealth, promoting economic growth, and quality life improvement, without damaging the environment, applying quality management principles and ISO standards, as efficient and effective tools, and this is needed immediately. On the other hand, scientific management of factors of production requires ISO standards application, so, a connection and relations between sustainable development and ISO standards, should exist. The general outcome of the research (also the practical and social outcome, as well as contribution to the field), is that looking forward to achieving and maintaining sustainable development scenarios, for all interested parties, individuals, public and private institutions, decision-makers, and civil society, applying quality management principles and ISO standards, as efficient and effective tools, as an immediate need, all parties should look forward to making sure building relations and connections between SDG and ISO standards, a connection which currently doesn’t exist.

This article discussed the major effect of blockchain technology for sustainable performance in Supply chain management (SCM). Blockchain technology is a technology that performs several operations without letting the information get lost. This digital technology of blockchain will show the potential to reshape the management of supply chain operations in various companies. We will investigate the impact of blockchain technology in relation to efficiency and sustainability. As an example recently the operations in the airport industry have been improving due to technological advances as blockchain technology is handling all the information in the warehouses about product delivery and services in SCM. This technology allows companies to track all types of transactions more securely and transparently and blockchain technology shows benefits, especially in terms of improving Operational Management. The technological disruptions that have an effect on operations must include A-CDM (Airport collaborative decision-making) disruption management and there should be a collaborative network where everyone shares mutual trust and common culture in order to avoid disruption. Airports are still under research in terms of managing blockchain technology efficiently and effectively. The database which is decentralized causes the transactions to be transparent, reliable, traceable, and efficient to supply chain management. This article will be useful to understand the importance of blockchain technology for maintaining sustainability in the operations of SCM along with that we will take an example of SCM in the airport industry to understand how this technology is used there.

It is important for public health to monitor infectious agents in domestic animals. This study aimed to detect of bacterial and fungal agents in the skin of various domestic animals. A total of 263 skin samples were collected during 2021-2023 from 147 cats, 102 dogs, 10 cows, 3 rabbits, and 1 iguana. Bacteriological examination indicated that 37.6% of the samples were positive. S. pseudintermedius (35.4%) was the dominant bacteria in all isolates, followed by P. aeruginosa (23.2%). S. aureus was isolated from one rabbit sample and P. aeruginosa from one iguana sample. These findings add to the limited number of studies on these species. As a result of mycological examinations, 61.6% of all samples were identified as positive by cultural examination. Saprophytes were found in 41.1% of all samples, specifically A. niger (30.6%), Penicillium spp. (28.7%), A. fumigatus (16.7%), Alternaria spp. (15.7%), Mucor spp. (4.6%), and A. flavus (3.7%). The high prevalence of saprophytes was correlated with environmental contamination. Dermatophytes were isolated in 20.5% of all samples. M. canis was the dominant dermatophyte (64.8%), followed by T. mentagrophytes (31.5%) and M. ferrugineum (3.7%). The higher prevalence of dermatophytosis in spring (51.9%), was associated with rainy seasonal conditions in Turkey.

A Convolutional Neural Network (CNN) is a class of deep neural network most commonly used in analyzing visual images. Various systems and applications have been built to detect and classify the objects in a faster way taking CNN as its foundation. In this paper, we introduce a model to identify and classify people wearing ID card.Our model uses an object detection system called YOLO (You Only Look Once) for detecting and classifying objects in real-time videos. In the YOLO algorithm, a single convolutional network predicts the bounding boxes and the class probabilities for these boxes. We aim to use our model for authentication, surveillance and security purposes at organizations, corporations and educational institutions to detect an unauthorized person at the premises or somebody without a valid identification document. Using the object detection and classification, we aim to build a model which would alert the respective authorities on the matter.
