 ABSTRACT
Anemia is a major health problem in society and often occurs throughout the world, especially in developing countries like Indonesia. This disorder is a cause of chronic disability and has a significant impact on health, economic and social situations. About 30% or 2.2 billion people worldwide suffer from anemia, most of whom live in tropical areas. The global prevalence of anemia is approximately 51%. The incidence of anemia in North Sumatra Province according to data from the North Sumatra Provincial Health Service in 2015 reached 57.1%, in 2016 it was 54.5%, and in 2017 it increased to 58.2%. Anemia in adolescent in Medan City is still a public health problem because its prevalence is more than 25%. Even though many adolescent know about anemia, they do not know that anemia can be prevented by consuming blood supplement tablets according to the correct recommendations. So it is necessary to provide information regarding blood supplement tablets to adolescent in Mompang Village. The expected output target is increased knowledge between before and after the counseling is implemented, as well as awareness among adolescent to consume blood supplement tablets as recommended. The method used is counseling. The results of the service showed an increase in adolescent knowledge about blood supplement tablets in adolescent.

Abstract. Ammonia (NH3) is the major alkaline species in the atmosphere and plays an important role in aerosol formation, which affects local air quality and the radiation budget. NH3 in the upper troposphere and lower stratosphere (UTLS) is difficult to detect, and only limited observations are available. We present two-dimensional trace gas measurements of NH3 obtained by the airborne infrared imaging limb sounder GLORIA (Gimballed Limb Observer for Radiance Imaging of the Atmosphere) that was operated on board the research aircraft Geophysica within the Asian monsoon anticyclone during the StratoClim campaign (July 2017) and on board HALO (the High Altitude and LOng Range research aircraft) above the South Atlantic during the SouthTRAC campaign (September–November 2019). We compare these GLORIA measurements in the UTLS with results of the CAMS (Copernicus Atmosphere Monitoring Service) reanalysis and forecast model to evaluate its performance. The GLORIA observations reveal large enhancements of NH3 of more than 1 ppbv in the Asian monsoon upper troposphere but no clear indication of NH3 in biomass burning plumes in the upper troposphere above the South Atlantic above the instrument's detection limit of around 20 pptv. In contrast, CAMS reanalysis and forecast simulation results indicate strong enhancements of NH3 in both measured scenarios. Comparisons of other retrieved pollution gases, such as peroxyacetyl nitrate (PAN), show the ability of CAMS models to generally reproduce the biomass burning plumes above the South Atlantic. However, NH3 concentrations are largely overestimated by the CAMS models within these plumes. We suggest that emission strengths used by CAMS models are of lower accuracy for biomass burning in comparison to agricultural sources in the Asian monsoon. Further, we suggest that loss processes of NH3 during transport to the upper troposphere may be underestimated for the biomass burning cases above the South Atlantic. Since NH3 is strongly undersampled, in particular at higher altitudes, we hope for regular vertically resolved measurements of NH3 from the proposed CAIRT (Changing-Atmosphere Infra-Red Tomography Explorer) mission to strengthen our understanding of this important trace gas in the atmosphere.

Abstract. Data fusion of aerosol optical depth (AOD) datasets from the second generation of the Geostationary Korea Multi-Purpose Satellite (GEO-KOMPSAT-2, GK-2) series was undertaken using both statistical and deep neural network (DNN)-based methods. The GK-2 mission includes an Advanced Meteorological Imager (AMI) aboard GK-2A and a Geostationary Environment Monitoring Spectrometer (GEMS) and Geostationary Ocean Color Imager II (GOCI-II) aboard GK-2B. The statistical fusion method, maximum likelihood estimation (MLE), corrected the bias of each aerosol product by assuming a Gaussian error distribution and accounted for pixel-level uncertainties by weighting the root-mean-square error of each AOD product for every pixel. A DNN-based fusion model was trained to target AErosol RObotic NETwork (AERONET) AOD values using fully connected hidden layers. The MLE and DNN AOD outperformed individual GEMS and AMI AOD datasets in East Asia (R = 0.888; RMSE = −0.188; MBE = −0.076; 60.6 % within EE for MLE AOD; R = 0.905; RMSE = 0.161; MBE = −0.060; 65.6 % within EE for DNN AOD). The selection of AOD around the Korean Peninsula, which incorporates all aerosol products including GOCI-II, resulted in much better results (R = 0.911; RMSE = 0.113; MBE = −0.047; 73.3 % within EE for MLE AOD; R = 0.912; RMSE = 0.102; MBE = −0.028; 78.2 % within EE for DNN AOD). The DNN AOD effectively addressed the rapid increase in uncertainty at higher aerosol loadings. Overall, fusion AOD (particularly DNN AOD) showed improvements with less variance and a negative bias. Both fusion algorithms stabilized diurnal error variations and provided additional insights into hourly aerosol evolution. The application of aerosol fusion techniques to future geostationary satellite projects such as Tropospheric Emissions: Monitoring of Pollution (TEMPO), Sentinel-4, and Geostationary Extended Observations (GeoXO) may facilitate the production of high-quality global aerosol data.

Abstract. Forest systems are the main carbon sink after the oceans. However, due to climate change, an alarming number of tree species of the Northern Hemisphere are at risk of migrating northwards or becoming extinct. This is the case for the downy oak (Quercus pubescens), one of the main species constituting the forests close to the Mediterranean Sea in France. Our aim is to retrieve aboveground carbon (AGC) and underground root carbon (UGC) stocks of the downy oak forest at the Observatoire de Haute-Provence (OHP), located about 80 km north of Marseille, in order to provide a baseline against which to assess the effect of climate change on this model species. The study presented here is based on airborne lidar observations performed on May 2012 and field measurements from 2012, 2018 and 2023 in the OHP forest. The OHP forest consists of ∼ 75 % downy oak, which is highly sensitive to global warming. Field measurements indicate minimal changes in tree growth and density between 2012 and 2023, and thus its carbon storage efficiency remains stationary. As retrieved by lidar measurements, tree top heights (TTHs) are mostly between 5 and 12 m, with an uncertainty of around 1 m. The slow evolution of trees at the OHP site makes it appropriate to use lidar data recorded in 2012 to assess the carbon stock trapped in current forest biomass. By coupling allometric laws established from field measurements with lidar observations, we show that the quantities of carbon trapped in aboveground biomass are double those trapped in the root system. Over an area of ∼ 24 ha, mean values of 15 ± 14 tC ha−1 are assessed for the aerial biomass against 8–10 ± 3–7 tC ha−1 for the roots of diameter larger than 1 cm for low and high assessments. These values depend heavily on the height of the sampled trees themselves, as well as on their location on the OHP plateau (smaller trees, 5–6 m) or on the slope (tallest trees, 10–12 m). Using a Monte Carlo approach, the relative uncertainties in AGC were calculated to be of the order of 17 % and 11 % for trees 5–6 m and 10–12 m tall, respectively. For UGC, the relative uncertainties were calculated as 8 % and 5 % for the same tree heights, but the assumptions of the allometric model are associated with biases that can easily reach 100 %. Although the surface footprints are different, we show that there is a reasonable agreement between our airborne lidar measurements and the level 2B (TTH) and (aboveground biomass) operational products of the Global Ecosystem Dynamics Investigation (GEDI) mission on the International Space Station for data acquired between 2019 and 2022.
Quantifying mantle mixing through configurational entropy
Authors: van der Wiel Erik , Thieulot Cedric , van Hinsbergen Douwe J. J.
Published: July 2024

Abstract. Geodynamic models of mantle convection provide a powerful tool to obtain insights into the structure and composition of the Earth's mantle that resulted from a long history of differentiating and mixing. Comparing such models with geophysical and geochemical observations is challenging, as these datasets often sample entirely different temporal and spatial scales. Here, we explore the use of configurational entropy, based on tracer and compositional distribution on a global and local scale. We show means to calculate configurational entropy in a 2D annulus and find that these calculations may be used to quantitatively compare long-term geodynamic models with each other. The entropy may be used to analyse, with a single measure, the mixed state of the mantle as a whole and may also be useful to compare numerical models with local anomalies in the mantle that may be inferred from seismological or geochemical observations.
Model spread in multidecadal North Atlantic Oscillation variability connected to stratosphere–troposphere coupling
Authors: Bonnet Rémy , McKenna Christine M. , Maycock Amanda C.
Published: July 2024

Abstract. The underestimation in multidecadal variability in the wintertime North Atlantic Oscillation (NAO) by global climate models remains poorly understood. Understanding the origins of this weak NAO variability is important for making model projections more reliable. Past studies have linked the weak multidecadal NAO variability in models to an underestimated atmospheric response to the Atlantic Multidecadal Variability (AMV). We investigate historical simulations from Coupled Model Intercomparison Project Phase 6 (CMIP6) large-ensemble models and find that most of the models do not reproduce observed multidecadal NAO variability, as found in previous generations of climate models. We explore statistical relationships with physical drivers that may contribute to inter-model spread in NAO variability. There is a significant anticorrelation across models between the AMV–NAO coupling parameter and multidecadal NAO variability over the full historical period (r=-0.55, p<0.05). However, this relationship is relatively weak and becomes obscured when using a common period (1900–2010) and de-trending the data in a consistent way, with observations to enable a model–data comparison. This suggests that the representation of NAO–AMV coupling contributes to a modest proportion of inter-model spread in multidecadal NAO variability, although the importance of this process for model spread could be underestimated, given evidence of a systematically poor representation of the coupling in the models. We find a significant inter-model correlation between multidecadal NAO variability and multidecadal stratospheric polar vortex variability and a stratosphere–troposphere coupling parameter, which quantifies the relationship between stratospheric winds and the NAO. The models with the lowest NAO variance are associated with weaker polar vortex variability and a weaker stratosphere–troposphere coupling parameter. The two stratospheric indices are uncorrelated across models and together give a pooled R2 with an NAO variability of 0.7, which is larger than the fraction of inter-model spread related to the AMV (R2=0.3). The identification of this relationship suggests that modelled spread in multidecadal NAO variability has the potential to be reduced by improved knowledge of observed multidecadal stratospheric variability; however, observational records are currently too short to provide a robust constraint on these indices.

Authors: Rodríguez Yncio Grisel Andrea
Published: July 2024

La investigación busca explicar la integración de recursos digitales y gráfica ambiental en una estrategia transmedia como parte de la narrativa museográfica de museos en Lima. La hipótesis sugiere que, si existe dicha integración, entonces se fomentará una cultura participativa que trascienda el espacio físico de las exhibiciones. Se utilizó un método de estudio cualitativo etnográfico con alcance descriptivo, en el que se realizó un análisis visual de recursos gráficos e interactivos, así como de la manera en que los visitantes se relacionan con ellos. Los museos estudiados fueron el Museo Nacional de Arqueología, Antropología e Historia del Perú; el Lugar de la Memoria, la Tolerancia y la Inclusión Social; y el Museo de Arte de Lima. En los principales resultados, se encontró que la digitalización de los contenidos no promueve imperiosamente una participación en el entorno virtual. Además, en el espacio físico, los usuarios buscan diferentes estímulos con los que interactuar y estos no necesariamente provienen de una pantalla. Se concluye que existe una incipiente cultura participativa que trasciende el espacio físico de las exhibiciones museográficas, y que depende exclusivamente de que estos sean formulados, de acuerdo con una narrativa transmedial coherente, integrando recursos digitales y gráfica ambiental.

Published: July 2024

Background/Aims: Obtaining and maintaining corticosteroid-free remission are important goals of treatment for ulcerative colitis (UC). Characteristics associated with achieving corticosteroid-free remission were assessed in filgotinib-treated patients in SELECTION, a 58-week, phase 2b/3 trial in moderately to severely active UC. Methods: This post hoc analysis used data from filgotinib-treated patients receiving corticosteroids at maintenance baseline in SELECTION. Univariate logistic regression was performed to assess induction baseline characteristics associated with 6 months of corticosteroid-free remission at week 58, defined as clinical remission without using corticosteroids for at least 6 months. Results: At maintenance baseline, 92 and 81 patients were receiving corticosteroids in the filgotinib 200 mg and filgotinib 100 mg groups, respectively. Age, body mass index, history of pancolitis, disease duration, fecal calprotectin levels, C-reactive protein levels, Mayo Clinic Score, concomitant corticosteroids, immunomodulators, and aminosalicylates had no statistically significant effect on the likelihood of achieving corticosteroid-free remission. Baseline characteristics associated with increased odds of corticosteroid-free remission were Mayo Clinic Endoscopic Subscore of 2 (vs. 3) in the filgotinib 200 mg and filgotinib 100 mg groups, and female (vs. male) sex, current (vs. former or never) smoking, and being biologic‑naive (vs. experienced) in the filgotinib 200 mg group. Conclusions: Steroid tapering can be achieved in patients with UC receiving filgotinib 200 mg independently of baseline characteristics such as clinical activity and duration of illness. However, the likelihood of achieving corticosteroid-free remission was higher among patients who were biologic-naive, current smokers, had low endoscopic inflammatory burden and who were female.

The need of switch to burn non-design fuel arises during the thermal power plants long-term operation. The choice of replacing coal is quite complicated and currently being solved by various non-design fuels experimental combustion on a specific power boiler. The aim of the work is to develop criteria assessing non-design coal burning possibility in a specific furnace before experimental combustion. The stated goal is achieved with the help of numerical combustion modeling regarding various coals at the pre-critical parameters boiler furnace with an average composition ranking by the lower calorific value. 2 burning ratios have been proposed based on foreign experience: the fuel ratio and the degree of fuel burnout. The first is the ratio of the fuel carbon to volatile substances contents, which in this work are taken as an analytical mass. The second is calculated with the proposed formula, which, instead of the combustible content in fly ash, use mechanical underburning widely included in the technical calculations. Combustion zones with the degree of the acceptable fuel burnout according to the standards and with its excess are distinguished. The limit of possible coal combustion according to the fuel coefficient is found as well. It is shown that this furnace is quite universal for burning a wide range of coals, although it was originally designed for burning brown coal. It is not recommended to burn only lean and low-caking bituminous coals, anthracites and brown coals with calorific value less than 11.5 MJ/kg or humidity more than 40%. The obtained results are significant for the preliminary assessment of non-design fuel combustion and narrowing the range of fuels under consideration. Other the boiler conversion consequences for non-design fuel should be taken into account for the final decision, and above all, the probability of the heating surfaces slagging.
Determining the Idle Mode of the Last Stages of Powerful Steam Turbines for Wet Steam Area
Authors: Senetskaya D.O. , Senetskyi A.V.
Published: July 2024

Increasingly, low-capacity electricity generating installations using renewable energy sources are becoming widespread. They bring imbalance to the energy system. Frequency control is carried out using powerful steam turbines. To ensure reliable and efficient operation of powerful steam turbines, it is important to understand the processes occurring in the last stages of the low pres-sure cylinder. At present, there is no approach to determining the idle mode (the moment of transition from the generation of mechanical power to its consumption) for large fanning stages. The purpose of the work is to develop an approach to estimating the relative volumetric steam flow rate of steam for large fanning stages, which characterizes the idle mode. This goal is achieved by developing a dependence to determine the idle mode for large fanning stages at nominal operating mode in a compressible medium using the results of an experimental study of model stages for high power turbines. The most important result is the satisfactory agreement between the values of volume flow rate obtained during the calculation, using the proposed method, with experimentally studies for the T-250/300-240 turbine last stage. The calculation error is about 3%. The significance of the results obtained is that the proposed approach allows determining the idle mode of the low pressure cylinder stages of steam turbines quickly and ac-curately during operation and design, which makes it possible to increase the efficiency and reli-ability of power units.

The object of the study is to enhance operational efficiency and reduce fuel consumption of autonomous underwater vehicles during the monitoring of underwater electrical and optical cables based on FCA under conditions of uncertainty. To achieve the goal of the research fuzzy cellular automata are used, combining the advantages inherent in traditional cellular automata and provided by the capabilities of fuzzy sets and fuzzy logic. The cable location uncertainty is caused by possible earthquakes, turbulent currents, random impacts of anchors or fishing gear, cable fouling by marine vegetation and terrorist attacks. The developed approach allows to synthesise a Pareto-optimal vehicle route along the estimated coordinates of the object of study, providing minimum fuel consumption for minimum cable inspection time and satisfying the given system of constraints. Formal models are based on the use of fuzzy cellular automata, which are used to describe the three-dimensional model of the operating environment, zones and objects that hinder or limit the movement, and the behaviour of the underwater vehicle. The most significant results are the formal description of the problem solution space, and the method of modelling the route of an autonomous underwater vehicle in space to improve the efficiency and quality of the solution of the problem of monitoring the state of the object of interest. The significance of the results obtained is the possibility of solving a complex multi-criteria optimisation problem of finding the route of an autonomous underwater vehicle to monitor the cable system in three-dimensional space.

Over the past thirty years, it is evident that there has been little change in the methodology of teaching Science, Technology, Engineering, And Mathematics (STEM) in Nigeria. Consequently, Nigerian students have lagged, encountering difficulties in science and math proficiency. Despite national reform initiatives aimed at enhancing the situation, the absence of uniformity and a unified effort has resulted in negligible alterations in instructional methods. This research examined data from student and teacher programs conducted by State Universal Basic Education Board (SUBEB). The focus was on two programs implemented over a two-year period: STEM Bootcamps for children and Teacher training initiatives. The results indicated that these programs successfully enhanced learning and forged a robust link to the real world. Even though it was their initial encounter with STEM pedagogy, both educators and students recognized its worth and found it advantageous in grasping the concepts addressed during the programs. These favorable outcomes sparked conversations about expanding the pilot programs and considering the ramifications for policy and future research.

The capture of food, the process of chewing, the act of swallowing play an important role in the nutrition process. The mandibular salivary gland is located in the interdigital space, caudally partially covered by the parotid salivary gland. Its duct runs along the rostral and ventral margin and along the medial surface of the hyoid gland to the hyoid wart, where it opens. The mandibular salivary gland is responsible for the production of saliva, which flows through the duct into the oral cavity. Saliva plays an important role in the chewing process: wetting food, enveloping it in a food lump. The quality of an animal's life and productivity depend on the condition of the oral cavity organs and their functioning. The purpose of the study is to study the features of the histological structure of the oral cavity organ (mandibular salivary gland) of the Anglo–Nubian goat breed. 7 heads were taken and materials for histological examination were selected. The cadaverous material was obtained from a farm located in the Moscow region. Sections 5-7 microns thick were made, which were stained with hematoxylin and eosin and trichrome by Masson. Some of the sections were stained with Alcyan blue (pH 2.5), followed by pre-staining with Mayer hematoxylin, and Schiff-iodic acid according to McManus. It has been established that the Anglo-Nubian goat is characterized by patterns of histological structure of the mandibular salivary gland common to mammals. The mandibular salivary gland is of a mixed type, has an alveolar-tubular structure. The mandibular salivary gland belongs to the extramural glands and secretes a mixed secret. Groups of serous secretory cells cover the mucous part of the terminal section from the outside in the form of a half moon.

Almost every year in Kazakhstan there are outbreaks of anthrax with registration of the disease in farm animals and people. The purpose of the research was to analyze the epizootic situation regarding anthrax in the Republic of Kazakhstan in the period from 2014 to 2023. Analysis of the data showed that in the period from 2014 to 2023, anthrax infection in Kazakhstan was recorded almost annually. The distribution of cases of registration of this infection in different regions of the republic varied significantly. In a number of regions, during the specified period, anthrax infection was recorded once, and in some regions the infection was diagnosed two, three or more times. Studies of blood serum in animals after immunization anthrax vaccine showed that most animals have post-vaccination antibodies, which helps reduce the risk of anthrax in animals and humans and the emergence of a new epizootic anthrax outbreak.
Diagnosis and treatment of Cryptosporidiosis in dogs

Published: July 2024

Among the etiological factors of gastroenteritis in dogs, cryptosporidiosis occupies about 40%. Gastroenteritis is one of the most common pathologies in veterinary practice. One of the causes of gastroenteritis is parasitic infestations, including coccidiosis. The relevance of this topic is due to the fact that there is a very small amount of materials covering cryptosporidiosis specifically in dogs. It is necessary to pay attention to this cococidosis, since it has an atypical life cycle, diagnosis, and at the same time is a zoonotic disease. This research paper presents clinical cases of 10 dogs that were spontaneously infected with cryptosporidiosis and examined in a veterinary clinic in St. Petersburg. Sick animals underwent a general clinical examination, which included: clinical examination, palpation, and laboratory tests. Blood samples were taken for clinical and biochemical analysis, general stool analysis, followed by staining. A rectal swab was taken for PCR testing. In adult dogs, clinical signs of this disease may be atypical. The picture of gastroenteritis is accompanied by diarrhea syndrome with watery feces and a large amount of mucus. The increase in segmented neutrophils is explained by parasitic invasion and caused intestinal inflammation. The increase in lactate degylrogenase is explained by increased destruction of enterocytes due to parasitism by protozoa - cryptosporidium. A general stool test is not informative for the detection of coccidia oocysts. It is PCR research that is an informative diagnostic method with extremely high sensitivity of up to 98%. The drug “Stop-coccid 5%” at a dosage of 0.2 ml/kg is an effective treatment for cryptosporidiosis in dogs. “Stop-coccid 5%” is a low-hazard substance; in recommended doses it does not cause complications or side effects, and does not interfere with the formation of immunity in animals. It is also necessary to carry out symptomatic treatment along with antiparasitic treatment, including antibiotic therapy (for example, a drug from the macrolide group «Tylosin»), since intestinal dysbacteriosis occurs due to the destruction of enterocytes.
