Three cases of double infection with elephant endotheliotropic herpesvirus (EEHV) types 1A and 4 in captive Asian elephants are presented. The first calf was a 4-year-old female that showed initial signs of lethargy and depression. The second calf was a 6-year-old female that displayed signs of depression and diarrhea and died within 48 h of the start of supportive treatment. The third was a 2-year-old male that died suddenly while living with the herd. Necropsies were performed in the first and second elephants, while only a tongue sample was collected from the third calf. EEHV infection was confirmed via quantitative PCR (qPCR) and gene sequencing, revealing double subtypes of EEHV1A and -4 infections. This study describes the hematological and pathological characteristics within the host following double EEHV infection.

Published: March 2024

Water utilities face the challenge of addressing physical leaks generated from the aging of water distribution systems and the need for more innovative practices to manage water infrastructure efficiently. Water leakages are typically modeled using extended period simulations based on Bernoulli’s equation. However, this approach must be revised since traditional methods do not appropriately simulate variations induced by regulating valves. In this study, the authors developed a mathematical model based on the mass oscillation equation, which is well-suited for predicting water leakages while accounting for system inertia from regulating valves. This approach is versatile and can be applied to all parallel pipe systems. A comprehensive practical application involving two parallel pipes has been conducted. The aim is to provide engineers and designers with a tool to assess the total volume of water leaks caused by regulating valves in real-world water distribution networks. Furthermore, the study includes a comparative analysis with a single pipe configuration to illustrate how parallel systems lead to increased leaks in contrast to simpler pipe setups.
Are Non-Conventional Water Resources the Solution for the Structural Water Deficit in Mediterranean Agriculture? The Case of the Segura River Basin in Spain
Authors: Gómez-Ramos Almudena , Blanco-Gutiérrez Irene , Ballesteros-Olza Mario , Esteve Paloma
Published: March 2024

The water sustainability of the Segura River Basin (SRB), located in southeastern Spain, is being challenged as conventional available water sources fall short of meeting the authorised demands of the basin. In recent years, non-conventional water (NCW), such as desalinated and reclaimed water, has become part of the resource pool. However, it has not yet become crucial for irrigation water supply due to its relatively high cost and lower quality compared to conventional water. The new political framework in Spain, developed in the context of ecological transition, marks a notable shift for non-conventional water as a strategic resource for agriculture. This study examines the drivers and barriers influencing its acceptance through an analysis of farmers’ perceptions, conducted through interviews with twelve irrigation communities’ (ICs) representatives of the basin. Discriminant analyses of the data show that the farmers’ experience, along with factors pertaining to production, storage, and transportation costs, determines the acceptance and use of NCW.

Published: March 2024

Prymnesium parvum is a harmful alga found in brackish waters worldwide whose toxins can be lethal to aquatic organisms. Established field methods to control blooms of this species, however, are unavailable. Earlier studies showed that various extracts of giant reed (Arundo donax) can suppress P. parvum growth and that ellipticine, an allelochemical present in giant reed, is a potent algicide against this species. The unintended effects of giant reed products on nontarget organisms, however, are not fully understood. This study determined the effects of giant reed leachate (aqueous extract of dried chips) and ellipticine on growth of P. parvum and the green microalga Chlorella sorokiniana; survival and reproduction of the planktonic crustacean Daphnia pulex; and hatching success, larval survival, and larval swimming behavior of the teleost fish Danio rerio. Leachate made with 3 g chips L−1 was lethally toxic to P. parvum and D. pulex, stimulated C. sorokiniana growth, and impaired D. rerio behavior. Leachate at 1 g L−1 fully suppressed P. parvum growth, had moderate effects on D. pulex reproductive output, and had no effects on D. rerio. Ellipticine at 0.01 mg L−1 irreversibly inhibited P. parvum growth, acutely but reversibly inhibited C. sorokiniana growth, slightly delayed D. pulex reproduction, and had no effects on D. rerio. These observations suggest that when applied at appropriate concentrations, natural products derived from giant reed can be used as tools to specifically control P. parvum growth with minimal effects on nontarget species.
In a Good Way: Braiding Indigenous and Western Knowledge Systems to Understand and Restore Freshwater Systems
Authors: Mehltretter Samantha , Bradford Andrea , Longboat Sheri , Luby Brittany
Published: March 2024

Insights from Indigenous and Western ways of knowing can improve how we understand, manage, and restore complex freshwater social–ecological systems. While many frameworks exist, specific methods to guide researchers and practitioners in bringing Indigenous and Western knowledge systems together in a ‘good way’ are harder to find. A scoping review of academic and grey literature yielded 138 sources, from which data were extracted using two novel frameworks. The EAUX (Equity, Access, Usability, and eXchange) framework, with a water-themed acronym, summarizes important principles when braiding knowledge systems. These principles demonstrate the importance of recognizing Indigenous collaborators as equal partners, honouring data sovereignty, centring Indigenous benefits, and prioritizing relationships. The A-to-A (Axiology and Ontology, Epistemology and Methodology, Data Gathering, Analysis and Synthesis, and Application) framework organizes methods for braiding knowledge systems at different stages of a project. Methods are also presented using themes: open your mind to different values and worldviews; prioritize relationships with collaborators (human and other-than-human); recognize that different ways of regarding the natural world are valid; and remember that each Indigenous partner is unique. Appropriate principles and practices are context-dependent, so collaborators must listen carefully and with an open mind to identify braiding methods that are best for the project.

Published: March 2024

Microbial communities associated with seagrass beds play a crucial role in maintaining the balance of seagrass ecosystems. However, the driving mechanisms behind the structure and functional succession of seagrass microbial communities are still unclear despite the close interaction between seagrass and surrounding microorganisms. To enhance our knowledge of the diversity and functional characteristics of microbial communities in seagrass beds, we employed 16S rRNA gene amplicon sequencing to investigate bacterial communities in seagrass leaves, roots, seawater, and sediments in Caofeidian Zostera marina seagrass beds of Hebei Province, Northern China. Our results highlighted that specific types of bacteria were enriched in different sample compartments, indicating the importance of habitat in influencing microbial diversity and community structure in seagrass bed ecosystems. Notably, the microbial community structure of seagrass leaves and roots showed more similarity to that found in seawater and sediments. Among all the samples, the phylum Pseudomonadota exhibited the highest relative abundance, particularly in sediment samples where they accounted for over 95% of the total bacterial population. In addition, the enrichment of Vibrio, an opportunistic pathogen in several plant samples, alerted us to seagrass and its surrounding marine environments. Finally, functional predictions of microbial communities using PICRUSt2 revealed variations in microbial functions, indicating specific metabolic preferences of microbial communities in different natural environments. The present research sheds light on the mechanisms underlying microbial community succession and their ecological function in seagrass beds.

Published: March 2024

The introduction of the first list of priority pathogenic fungi by the World Health Organization stresses the need to research and develop public health actions to mitigate infections caused by fungi. One of those actions involves the water disinfection systems, which comprise classical and alternative methods that have been developed in the last decades. Thereby, this work reviews the disinfection of fungi by classical methods such as chlorination, ozonation, and ultraviolet (UV) treatments and alternative advanced oxidation processes (AOPs) such as photo-Fenton, photocatalysis, or couplings of UV with peroxides. The matrices of aquatic systems (sewage, groundwater, drinking water, among others) were considered. A bibliometric analysis is performed initially, and then some aspects of the resistance to antifungals are presented, and the efficiency of the diverse processes in the reduction in fungal loading is also revised. Herein, it is shown the role of the disinfecting agents (e.g., chlorine, hydroxyl radical, or light) and their effects on fungi structures (e.g., direct DNA damage, or indirect damage due to the action of radicals). Moreover, gaps, such as the treatment of antifungal-resistant fungi and limited information about combinations among AOPs, related to the disinfection of water polluted by fungi, were identified.

Published: March 2024

As an important hydrological ecosystem component, the glacier basin has great significance for climate and environment, and it is also linked to regional water sustainability. In this paper, the sampling and isotope analysis of glacial ice, ice-melt water, river water (river midstream and river downstream), groundwater (spring), and precipitation were carried out in a hydrological year of the Mingyong Glacier basin, which is located at the Meili Snow Mountains, Southeastern Tibetan Plateau. At the same time, the hydrograph separation of the recharge sources of the lower mountain pass is studied. The results show that the range of δD, δ18O, and d-excess (deuterium excess) in natural water bodies are significantly different, and the precipitation is the most obvious. The high values of δD and δ18O in the water samples all appeared in spring and summer, and the low values appeared in autumn and winter, while glacial ice showed opposite trends. Meanwhile, the local meteoric water line (LMWL) of the Mingyong Glacier basin is δD = 8.04δ18O + 13.06. The End-Member Mixing Analysis (EMMA) was adopted to determine the sources proportion of river water (river downstream) according to the δD, δ18O, and d-excess ratio relationships. The results showed that the proportion of ice-melt water, groundwater, and precipitation in the ablation period was 80.6%, 17.2%, and 2.2% as well as 19.2%, 73.1%, and 7.7% in the accumulation period, respectively. Ice-melt water has a higher conversion recharge rate to groundwater and indirectly recharges river water, especially in nonmonsoon seasons. In other words, the main recharge source of river water in the lower reaches of the Mingyong Glacier basin during the ablation period is ice-melt water. In the accumulation period, the main recharge source of river water in the lower reaches of the Mingyong Glacier basin is groundwater, while nearly half of the recharge of groundwater comes from ice-melt water. Therefore, regardless of the ablation period or the accumulation period, ice-melt water is sustainable and important to this region.

There is no doubt that seagrass beds constitute one of the most productive ecosystems in shallow coastal waters. Despite this, picoplankton in seagrass ecosystems has received relatively little attention. The purpose of this study was to compare picoplankton growth and mortality rates between seagrass and unvegetated habitats using chamber incubations. We tested two main hypotheses: (i) incubation with seagrass would result in higher bacterial growth rates due to increased DOM release from seagrass photosynthesis, and (ii) Synechococcus spp. would be lower in the presence of seagrass due to competition for inorganic nutrients. Bacterial growth rates were higher in seagrass chambers (2.44 d–1) than in non-seagrass chambers (2.31 d−1), respectively, suggesting that organic carbon coming from the seagrass community may support bacterial production. Furthermore, the growth rate of Synechococcus spp. was significantly lower in the seagrass treatment than in the non-seagrass treatment, likely reflecting nutrient competition with the seagrass. Small-scale chambers proved to be a useful tool for studying the factors controlling spatial and temporal patterns of picoplankton across different habitats. Furthermore, future studies should examine picoplankton growth over a wider range of spatial scales in seagrass beds and adjacent unvegetated sediment.
A New Classification Rule-Set for Mapping Surface Water in Complex Topographical Regions Using Sentinel-2 Imagery
Authors: Yang Xiaozhou , Hong Liang
Published: March 2024

Surface water is a critical natural resource, but its mapping accuracy is vulnerable to cloud cover, snow, shadows, and diverse roofing materials. Recognizing the limitations of a single threshold segmentation method that fails to achieve high-precision extraction of surface water in complex terrain areas, this study introduces a multiple threshold water detection rule (MTWDR) method to improve water extraction results. This method uses the multi-band reflectance characteristics of ground features to construct a water index and combines brightness features with the Otsu algorithm to eliminate interference from highly reflective ground features like ice, snow, bright material buildings, and clouds. The Yunan–Guizhou Plateau was selected as the study area due to its complex terrain and multiple types of surface water, and experiments were conducted using Sentinel-2 data on the Google Earth Engine (GEE). The results demonstrate that: (1) The proposed method achieves an overall accuracy of 94.08% and a kappa coefficient of 0.8831 in mountainous areas. In urban areas, the overall accuracy reaches 95.15%, accompanied by a kappa coefficient of 0.8945. (2) Compared to five widely used water indexes and rules, the MTWDR method improves accuracy by more than 3%. (3) It effectively overcomes interference from highly reflective ground features while maintaining the integrity and accuracy of water boundary extraction. In conclusion, the proposed method enhances extraction accuracy across different types of surface water within complex terrain areas, and can provide significant theoretical implications and practical value for researching and applying surface water resources.

Published: March 2024

Organic sun-blocking agents are recognized as emerging pollutants of the aquatic environment. The consequences and effects of these harmful substances on aquatic organisms are not fully understood, particularly in the context of Romania. This study examines the presence and environmental hazards posed by ten UV filters found in the Danube River. Six of the ten targeted contaminants were detected in surface water samples: 2-hydroxy-4-methoxy-benzophenone (BP-3), 2,4-dihydroxy benzophenone (BP-1), 2,3,4-trihydroxy benzophenone (234HBP), 2,2′-dihydroxy-4-methoxy-benzophenone (BP-8), 2-hydroxy-4-methoxy-4′-methyl-benzophenone (BP-10), and benzyl salicylate (BS). In sediment samples, seven of the ten compounds were identified: BS, BP-3, 4-hydroxybenzophenone (4HBP), BP-1, 234HBP, 2,2′,4,4′-tetrahydroxybenzophenone (BP-2), and BP-10, with different frequencies. The correlation coefficients showed strong relationships between benzophenone derivatives in surface water samples and a common contamination source for BP-3 and BS in sediment samples. In the assessment, the risk quotient (RQ) for BP-1 in fish was determined to be 1.81. Similarly, RQ values for BP-3 were calculated as 1.24 for Daphnia magna and 57 for fish, suggesting that these UV filters could potentially present substantial hazards to the aquatic ecosystem. The study findings indicate that additional research is needed to investigate the presence and potential risks of organic sun-blocking agents in surface waters, with a particular emphasis on densely populated areas in Romania.

Published: March 2024

Recreational water activities are widely recognized to have a positive impact on our physical and mental well-being. However, recreational water sources and their management are also a risk factor for human health due to different agents, including the overgrowth of cyanobacteria and algae. The presence of cyanobacteria and algae in recreational waters represents a One Health threat because of their potential release and the overuse of biocides. These organisms have the potential to metabolize organic matter and produce thermophilic and thermotolerant toxins. Moreover, different species of algae are involved in biofilm formation processes, thus impacting water quality and safety and also posing risks to the environment and animal and human health. Different species of algae participate in biofilm formation and have an impact on managing water and equipment maintenance. By searching literature databases, e.g., PubMed, we reviewed the state of the art, providing basic definitions, taxonomy, and epidemiological or medical issues related to the recreational uses of water. Methods of treatments and monitoring were summarized, considering both traditional and innovative strategies. Public health and surveillance approaches focus on the detection of toxins, the formation of biofilms, and the understanding of the benthonic and planktonic components as part of the larger microbial biodiversity. The review process allowed us to acknowledge that this is the first comprehensive overview of algae in recreational waters carried out within a wider One Health outlook.

Published: March 2024

This study presents the efficiency of TSS and organic pollutants (BOD5 and COD) removal in a hybrid constructed wetland wastewater treatment plant (VF-HF type) with an aeration system. This study was conducted over 6 years (2017–2022) in a facility with a capacity of 4.5 m3/day located in southeastern Poland and designed to treat real domestic wastewater from a school building. The studied facility consists of a three-chambered septic tank, a pumping station with an aeration system, and two beds with vertical and horizontal flow planted with giant miscanthus and willow. As a result of artificial aeration, the dissolved oxygen concentration in wastewater after mechanical treatment increased significantly, by an average of 1.18 mg O2/L, and was negatively correlated with wastewater temperature. The cumulative pollutant removal effects of the treatment plant (primary settling tank + VFCW + HFCW) were 81% for TSS, 98% for BOD5, and 89% for COD. There was no statistically significant effect of aeration on the organic pollutant removal effects in the VF bed, and such an effect was found for the temperature of wastewater entering the VF bed. The TSS, BOD5, and COD removal effects in the VF bed and BOD5 in the VF-HF system were positively correlated with air temperature. The technological reliability of the treatment plant was 98% for TSS and 100% for BOD5 and COD. The use of artificial aeration of wastewater makes it possible to achieve high organic pollutant removal efficiency in SSF CWs and to compensate for limitations due to the reduction in the area of constructed wetland beds.
A Comprehensive Numerical Overview of the Performance of Godunov Solutions Using Roe and Rusanov Schemes Applied to Dam-Break Flow
Authors: Elong Alain Joel , Zhou Ling , Karney Bryan , Xue Zijian , Lu Yanqing
Published: March 2024

As open channel simulations are of great economic and human significance, many numerical approaches have been developed, with the Godunov schemes showing particular promise. To evaluate, confirm, and extend the simulation results of others, a variety of first- and second-order FVMs are available, with Rusanov and Roe schemes being used here to simulate the demanding case of 1D and 2D flows following a dam break. The virtual boundary cells approach is shown to achieve a monotonic solution for both interior and boundary cells, and while flux computation is employed at boundary cells, a refinement is only rarely used in existing models. A number of variations are explored, including the TVD MUSCL-Hancock (monotone upwind scheme for conservation laws) numerical scheme with several slope limiters in a quest to avoid spurious oscillations. The sensitivity of the results to both channel length and the ratio of downstream to initial upstream water depth is explored using 1D and 2D models. The Roe scheme with a Van Leer limiter as a slope limiter is shown to be both fast and slightly more accurate than other slope limiters for this problem, but the Rusanov scheme with different slope limiters works well for 1D simulations. Significantly, the selection of an appropriate slope limiter is shown to be best based on the ratio of the downstream to upstream water depth. However, this study focuses on the special case where the ratio of the initial depth downstream to upstream of the dam is equal to or less than 0.5, and these outcomes are compared to theoretical results. The 2D dam-break problem is used to further explore first- and second-order methods using different slope limiters, and the results show that the Superbee limiter can be problematic due to an observed large dispersion in depth contours. However, the most promising approaches from previous studies are confirmed to deserve the high regard given to them by many researchers.

Authors: Ma Jun , Gong Yuqi , Xu Wenxia
Published: March 2024

The increasing level of intelligence in automobiles is driving a shift in the human–machine relationship. Users are paying more attention to the intelligent cabin and showing a tendency toward customization. As culture is considered to be an important factor in guiding user behavior and preference, this study innovatively incorporates cultural and human factors into the model to understand how individual cultural orientation influences user preference for innovative human-machine interaction (HMI) features. Firstly, this study considered five Hofstede cultural dimensions as potential impact factors and constructed a prediction model through the random forest algorithm so as to analyze the influence mechanism of culture. Subsequently, K-means clustering was used to classify the sample into three user groups and then predict their preferences for the innovative features in the intelligent cabin. The results showed that users with a higher power distance index preferred a sense of ceremony and show-off-related features such as ambient lighting and welcome mode, whereas users with high individualism were keen on a more open and personalized in-vehicle information system. Long-term orientation was found to be associated with features that help to improve efficiency, and users with a lower level of uncertainty avoidance and restraint were more likely to be attracted to new features and were also more willing to use entertainment-related features. The methodology developed in this study can be widely applied to people in different countries, thus effectively exploring the personal requirements of different individuals, guiding further user experience design and localization when breaking into a new market.

Published: March 2024

Due to its robustness in challenge variation in gait recognition domain, gait recognition is considered as one of the popular remote biometric identification technologies. Gait data may be reliably collected from a long distance and is difficult to conceal or copy. This article investigated the use of Kinect to identify gait in Saudis wearing loose-fitting apparel that conceals the majority of body shapes, such as thobes or abayas. Because these clothes cover the majority of the joints, it is difficult to determine gait. This research uses the Kinect sensor version 2 as a technique to choose the top three joints with the greatest identification results, which are then used for gait recognition. The Y coordinates of joints are used as features, which are then put into the K Nearest Neighbor classification algorithm. Several experiments were carried out, and the results demonstrate that the system has a promising identification rate and is capable of achieving a high recognition performance when identifying or recognizing a person while also dealing with obstacles associated with the types of loose clothing worn by the participants.
Exploration fonctionnelle du territoire des grands lacs alpins par le prisme des services écosystémiques
Authors: Baulaz Yoann , Dorioz Jean-Marcel , Peyrache-Gadeau Véronique
Published: March 2024

Les services écosystémiques (SE) des grands types d’écosystèmes, comme les forêts, agrosystèmes ou récifs coralliens, ont été

largement décrits, avec la proposition de méthodologies spécifiques, mais peu d’études se sont intéressées à modéliser les différents

services des grands lacs. Les lacs représentent pourtant l’une des principales sources d’eau douce, constituent des lieux de pêche, d’implantation des sociétés, des espaces de loisirs et de bien-être. Dans le cadre de notre étude, l’approche choisie est essentiellement géographique, plaçant au coeur de la modélisation conceptuelle la problématique spatiale et l’analyse des relations entre la qualité de l’eau et les services écosystémiques. Nous avons adapté à l’étude des SE rendus par les grands lacs alpins français (lac d’Annecy, lac du Bourget) et le Léman, l’un des modèles les plus utilisés pour caractériser les services : le modèle de la cascade (Potschin et Haines-Young, 2011). Ce modèle facilite l’identification et la caractérisation des variables-clefs écologiques, socio-économiques et techniques qui modifient le niveau des services rendus par les lacs, tout en mettant en lumière les interactions, rétroactions et chaînes causales associant les lacs à la société. Notre réflexion est une contribution à une nouvelle approche d’étude des territoires limniques, mobilisant le concept de service écosystémique en tant qu’outil de dialogue entre sciences et société. Le concept de SE invite dans l’immédiat à questionner les observatoires actuels de suivi des grands lacs qui sont centrés sur des indicateurs biophysiques (bioindication et flux hydrochimiques) pour qu’ils évoluent dans une approche plus systémique et intégrée, mieux adaptée pour répondre aux enjeux croisés du réchauffement climatique, de l’impact des micropolluants et pour anticiper les évolutions sociétales à venir.

U ovom radu nudim interpretaciju Mercierove kritike modernog pristupa spoznajnom problemu. Interpretacija počiva uglavnom na razlikovanju između objekta i stvari i na razlikovanju između objektivnoga i transobjektivnoga. Ta dva razlikovanja prožimaju Mercierovu kritiku, premda ih on nigdje ne razrađuje. U ovom radu, razrađujem te dvije distinkcije, da bih im potom pustio da, tako razrađene, prožmu Mercierovu kritiku iznova, s konačnim rezultatom koji, u osnovi, pokazuje da Mercierova kritika počiva na načelima objektivizma i objektivnoga realizma, nasuprot transobjektivnome realizmu, i na motivu povratka svijeta umu koji ga je stvorio, nasuprot modernoj koncepciji stvarnosti odvojene od uma.

Morphological Diversity and Morphometric Analysis of Commercially Traded Siganus spp. (Baronang Fish) in Tarakan's Beringin Market
Authors: Gaffar Syamsidar , Salwa Salwa , Sumarlin Sumarlin
Published: March 2024

This study aimed to investigate the morphological diversity and morphometric characteristics of commercially traded Siganus spp. (Baronang fish) in Tarakan's Beringin Market. A total of 100 fish specimens were collected from the market and analyzed using 23 morphometric measurements to identify differences in species and provide insights into their population structure. The measurements included total length, standard length, head length, head height, body height, caudal peduncle height, eye diameter, inter-eye distance, body width, and several other parameters related to fins and jaw length. The results showed a wide range of values for each morphometric parameter, suggesting a high degree of morphological variation among the sampled Baronang fish. For instance, the minimum and maximum total lengths were 15.07 cm and 22.17 cm, respectively, with an average of 10.84 cm and a standard deviation of 1.93. The head length ranged from 2.83 cm to 4.66 cm, with an average of 2.31 cm and a standard deviation of 0.46. Furthermore, the body height varied between 6.52 cm and 8.57 cm, with an average of 4.31 cm and a standard deviation of 0.53. These results, along with the other morphometric parameters, highlight the diverse morphological traits of Siganus spp. present in the Beringin Market. Comparisons with previous studies on Siganus spp. indicate that the morphological diversity observed in the present study is consistent with the known intraspecific variation within this genus. However, further research is required to determine if the observed differences are due to phenotypic plasticity, genetic differences, or a combination of both factors. This research contributes to a better understanding of the morphological diversity and morphometric characteristics of Siganus spp. in Tarakan's Beringin Market, which can be valuable for fisheries management, conservation efforts, and the sustainable use of this commercially important fish species. Future studies should explore the genetic diversity and population dynamics of Baronang fish to complement the findings of this study and further inform management strategies.

Published: March 2024

Indonesia merupakan Negara dengan tingkat penangkapan hiu terbesar di dunia, salah satu jenis ikan hiu yang ada di Indonesia adalah Paragaleus tengi. Hiu merupakan hasil tangkapan sampingan dari berbagai alat tangkap seperti jaring ingsang, pancing, pukat hela (trawl), pukat cincin, trammel net dan bubu. Permintaan akan ekspor hiu yang meningkat dapat mengakibatkan tingginya tingkat penangkapan akan hiu. Tujuan penelitian ini adalah memberikan gambaran karateristik ikan hiu (Paragaleus tengi). Karateristik biologi yang dimaksud adalah hubungan panjang berat, distribusi panjang dan nisbah kelamin. Pengambilan data dilakukan bulan Februari sampai bulan Agustus 2022. Sampel Ikan merupakan sampel ikan hiu yang didaratkan di Pelabuhan Perikanan Samudera Nizam Zachman (PPSNZ) Muara Baru-Jakarta Utara dan merupakan hasil tangkapan dari nelayan WPP 718. Hasil penelitian menunjukan ikan hiu yang tertangkap dominan memiliki panjang cagak berkisar 61,8-67,3 cm dengan pola pertumbuhan adalah allometrik negatif dimana pertumbuhan panjang lebih cepat dari pada pertumbuhan berat. Perbandingan jenis kelamin didapatkan ikan betina lebih banyak dari pada jantan tetapi dengan selisih yang tidak jauh, sehingga dari uji chi-square nisbah kelamin ikan  Paragaleus tengi masih seimbang.

Kerusakan ekosistem hutan mangrove telah banyak di laporkan oleh peneliti, dimana kerusakan tersebut dapat menyebabkan penurunan daya dukung lingkungannya. Oleh karenanya, penelitian ini difokuskan untuk menilai status daya dukung ekosistem hutan mangrove pada Daerah Aliran Sungai (DAS) Kayan dan Sembakung, untuk mengetahui status dan kecenderungan perubahan daya dukung ekosistem hutan mangrove sebagai penyedia pangan dan air tawar. Penilaian status dilakukan menggunakan pendekatan jasa ekosistem dengan pendekatan model matematik penjumlahan sederhana berbobot. Hasil penelitian adalah: (1) Ekosistem hutan mangrove pada DAS Kayan cenderung memiliki daya dukung “sangat tinggi” dan DAS Sembakung cenderung “sedang” sebagai penyedia pangan, sedangkan sebagai penyedia air tawar pada DAS Kayan daya dukungnya “sangat rendah” dan pada DAS Sembakung cenderung “rendah”; dan (2) Hutan mangrove mengalami perubahan tutupan lahan, menjadi mangrove sekunder, tambak, lahan terbuka, tambang, lahan terbangun, perkebunan, kebun campuran dan semak belukar, sehingga daya dukungnya sangat tinggi sebagai penyedia pangan, tetapi dalam penyediaan air tawar cenderung rendah dan bahkan sangat rendah.Kata kunci: Air; Ekosistem; Mangrove; Pangan

This research investigates the involvement of information technologies, including communication platforms and social media solutions, in managing earthquake disasters, specifically focusing on the February 2023 earthquake in Türkiye. In order to achieve this, a comparative framework is constructed, which incorporates four main categories, namely goal, providers, target phase, and platform. The data is gathered from diverse sources, and a total of 130 solutions are identified immediately following the February 2023 earthquake in Türkiye. After conducting a thorough examination of these solutions and removing any duplicates and irrelevant options, the final dataset comprises 89 unique solutions sourced from 82 providers. According to the study's findings, the solutions employed in mitigation and preparedness phases prioritize proactive measures and planning, while the ones in response phase witnesses a significant increase in activities related to aid campaigns, emergency response, information dissemination, and support services. The solutions in recovery phase further intensifies support services to aid affected communities.

La experiencia periodística del diario Tiempo Argentino desde su fundación en mayo de 2010 hasta diciembre de 2016. Rupturas y continuidades de un proyecto comunicacional contrahegemónico. Analizar y sistematizar el proceso de Tiempo Argentino. Su creación, desarrollo, caída y recuperación autogestionada por sus trabajadores a partir de uno de los interrogantes que dio origen al proyecto periodístico: ¿es posible hacer un diario de características contrahegemónicas en el marco del sistema tradicional de medios? Para la investigación se indagará sobre el contexto histórico político nacional de mayo 2010, cuando el diario salió a las calles por primera vez, a poco más de seis meses de la sanciónde la Ley de Servicios de Comunicación Audiovisuales, cuyos foros y audiencias previas a su aprobación en octubre de 2009 promovieron un amplio debate sobre el rol de los medios de comunicación en la sociedad. En especial, en relación con el gobierno de Cristina Fernández de Kirchner que había asumido en diciembre de 2007, y que pocos meses después enfrentó un prolongado conflicto con las patronales agropecuarias, en el que la prensa tradicional, en particular el Grupo Clarín y su socio La Nación tuvieron un claro posicionamiento opositor al kirchnerismo y en favor de las corporaciones rurales. En el siguiente trabajo se analizarán qué tradiciones del campo de la comunicación y qué matrices culturales se constituyeron en la creación de identidad de Tiempo Argentino como medio impreso urbano producido en la Ciudad de Buenos Aires. Se observarán los cambios que experimentó el diario desde su fundación en el marco de una empresa editora comercial y la ruptura del vínculo laboral con sus trabajadores que debieron constituir a mediados de 2016 una cooperativa autogestiva para mantener sus fuentes de trabajo y la continuidad del medio de comunicación. Se analizará la línea editorial del diario para determinar si ese cambio de figura empresarial modificó las características de medio contrahegemónico planteado por su núcleo fundador en 2010.
Los injertos en el maxilar inferior
Authors:   , Degrossi Osvaldo Jorge
Published: March 2024

Existe ya una dilatada experiencia en materia de injertos de huesos y de trasplantes, habiéndose hecho ya conciencia que las mayores posibilidades de éxito pertenecen al autoinjerto fresco. Sin embargo no se conoce aún a ciencia cierta el proceso de la rehabilitación de los mismos y si bien es cierto que el esqueleto del paciente debe jugar el rol principal, no es menos cierto que el medio ambiente en general debe de tener alguna participación, de cuyo conocimiento se establecerán las normas de la técnica, que habrán de dar al trasplante las mayores posibilidades de éxito. Desde que existe la posibilidad de obtener hueso heterotópico y desde que algunos factores pueden determinar la formación de hueso donde normalmente no existe (miositis osificante) parecerá lógico admitir que a expensas de cualquier tejido podemos obtener el hueso que se busca. Sin embargo la biología, la experimentación y la clínica parecen demostrar que sólo las posibilidades del esqueleto son capaces de crear hueso, no pudiendo servir a la clínica los casos de excepción en que se obtienen un rudimento de hueso, que por ahora no parecen útiles a la economía. Los trasplantes en el maxilar inferior sirven para demostrar toda la importancia del esqueleto del paciente en una región tan pobre en parte blandas, reducidas nada más que a la piel, vale decir, con un medio ambiente pobre, donde no se puede hacer derivar la osteogenesis de otros elementos que no sean los propios osteoblastos del.maxilar inferior. Cabe destacar a su vez que en una región como esta, cuyas características hemos señalado, los trasplantes de hueso generalmente prenden, siendo muy pocos los fracasos que consigna la bibliografía.
