Adequate nutrition is essential for healthy growth and development during childhood. Malnutrition refers to a pathological state resulting from a relative or absolute deficiency or excess of one or more essential nutrients. Wasting, stunting and underweight are anthropometric indicators commonly used to measure malnutrition in the toddler population. According to the World Health Organization (WHO), wasting, stunting, and underweight are defined as a Z-score of less than 2 standard deviations of weight for height, height for age, and weight for age, respectively.This community service activity aims to increase knowledge related to nutrition and health in preventing malnutrition in children under five. This health education method is carried out using health education methods for mothers with toddlers. The results obtained increase WUS's knowledge about malnutrition and nutritional fulfillment in an effort to prevent malnutrition in toddlers. It is hoped that this community service can increase mothers' knowledge and overcome the problem of malnutrition in toddlers.

Abstract. Deep convection initiated under different large-scale environmental conditions exhibits different precipitation features and interacts with local meteorology and surface properties in distinct ways. Here, we analyze the characteristics and spatiotemporal patterns of different types of convective systems over southeastern Texas using 13 years of high-resolution observations and reanalysis data. We find that mesoscale convective systems (MCSs) contribute significantly to both mean and extreme precipitation in all seasons, while isolated deep convection (IDC) plays a role in intense precipitation during summer and fall. Using self-organizing maps (SOMs), we found that convection can occur under unfavorable conditions without large-scale lifting or moisture convergence. In spring, fall, and winter, front-related large-scale meteorological patterns (LSMPs) characterized by low-level moisture convergence act as primary triggers for convection, while the remaining storms are associated with an anticyclonic pattern and orographic lifting. In summer, IDC events are mainly associated with front-related and anticyclonic LSMPs, while MCSs occur more in front-related LSMPs. We further tracked the life cycle of MCS and IDC events using the Flexible Object Tracker algorithm over southeastern Texas. MCSs frequently initiate west of Houston, traveling eastward for around 8 h to southeastern Texas, while IDC events initiate locally. The average duration of MCSs in southeastern Texas is 6.1 h, approximately 4.1 times the duration of IDC events. Diurnally, the initiation of convection associated with favorable LSMPs peaks at 11:00 UTC, 3 h earlier than that associated with anticyclones.

Published: July 2024

Abstract. Atmospheric transport inversions are a powerful tool for independently estimating surface CO2 fluxes from atmospheric CO2 concentration measurements. However, additional tracers are needed to separate the fossil fuel CO2 (ffCO2) emissions from non-fossil CO2 fluxes. In this study, we focus on radiocarbon (14C), the most direct tracer of ffCO2, and the continuously measured surrogate tracer carbon monoxide (CO), which is co-emitted with ffCO2 during incomplete combustion. In the companion paper by Maier et al. (2024), we determined discrete 14C-based and continuous ΔCO-based estimates of the ffCO2 excess concentration (ΔffCO2) compared with a clean-air reference for the urban Heidelberg observation site in southwestern Germany. The ΔCO-based ΔffCO2 concentration was calculated by dividing the continuously measured ΔCO excess concentration by an average 14C-basedΔCO/ΔffCO2 ratio. Here, we use the CarboScope inversion framework adapted for the urban domain around Heidelberg to assess the potential of both types of ΔffCO2 observations to investigate ffCO2 emissions and their seasonal cycle. We find that, although they are more precise, 14C-based ΔffCO2 observations from almost 100 afternoon flask samples collected in the 2 years of 2019 and 2020 are not well suited for estimating robust ffCO2 emissions in the main footprint of this urban area, which has a very heterogeneous distribution of sources including several point sources. The benefit of the continuous ΔCO-based ΔffCO2 estimates is that they can be averaged to reduce the impact of individual hours with an inadequate model performance. We show that the weekly averaged ΔCO-based ΔffCO2 observations allow for a robust reconstruction of the seasonal cycle of the area source ffCO2 emissions from temporally flat a priori emissions. In particular, the distinct COVID-19 signal – with a steep drop in emissions in spring 2020 – is clearly present in these data-driven a posteriori results. Moreover, our top-down results show a shift in the seasonality of the area source ffCO2 emissions around Heidelberg in 2019 compared with the bottom-up estimates from the Netherlands Organization for Applied Scientific Research (TNO). This highlights the huge potential of ΔCO-based ΔffCO2 to validate bottom-up ffCO2 emissions at urban stations if the ΔCO/ΔffCO2 ratios can be determined without biases.
Distinguishing mature and immature trees allows estimating forest carbon uptake from stand structure
Authors: Fischer Samuel M. , Wang Xugao , Huth Andreas
Published: July 2024

Abstract. Relating forest productivity to local variations in forest structure has been a long-standing challenge. Previous studies often focused on the connection between forest structure and stand-level photosynthesis (gross primary production – GPP). However, biomass production (net primary production – NPP) and net ecosystem exchange (NEE) are also subject to respiration and other carbon losses, which vary with local conditions and life history traits. Here, we use a simulation approach to study how these losses impact forest productivity and reveal themselves in forest structure. We fit the process-based forest model FORMIND to a 25 ha inventory of an old-growth temperate forest in China and classify trees as “mature” (fully grown) or “immature” based on their intrinsic carbon use efficiency. Our results reveal a strong negative connection between the stand-level carbon use efficiency and the prevalence of mature trees: gross primary production (GPP) increases with the total basal area, whereas net primary production (NPP) and NEE are driven by the basal area of immature trees. Accordingly, the basal area entropy, a structural proxy for the prevalence of immature trees, correlated well with NPP and NEE and had a higher predictive power than other structural characteristics, such as the Shannon diversity and height standard deviation. Our results were robust across spatial scales (0.04–1 ha) and yield promising hypotheses for field studies and new theoretical work.
Uncertainty quantification for overshoots of tipping thresholds
Authors: Lux-Gottschalk Kerstin Monika , Ritchie Paul David Longden
Published: July 2024

Abstract. Many subsystems of the Earth are at risk of undergoing abrupt transitions from their current stable state to a drastically different, and often less desired, state due to anthropogenic climate change. These so-called tipping events often present severe consequences for ecosystems and human livelihood that are difficult to reverse. One common mechanism for tipping to occur is via forcing a nonlinear system beyond a critical threshold that signifies self-amplifying feedbacks inducing tipping. However, previous work has shown that it is possible to briefly overshoot a critical threshold and avoid tipping. For some cases, the peak overshoot distance and the time a system can spend beyond a threshold are governed by an inverse square law relationship Ritchie et al. (2019). In the real world or complex models, critical thresholds and other system features are highly uncertain. In this work, we look at how such uncertainties affect the probability of tipping from the perspective of uncertainty quantification. We show the importance of constraining uncertainty in the location of the critical threshold and the linear restoring rate to the system’s stable state to better constrain the location of the boundary separating overshoots that avoid tipping from those that do not. We first prototypically analyse effects of an uncertain critical threshold location separately from effects due to an uncertain linear restoring rate. We then perform an analysis of joint effects of uncertain system characteristics within a conceptual model for the Atlantic Meridional Overturning Circulation (AMOC). The simple box model for the AMOC shows that these uncertainties have the potential to reverse conclusions for mitigation pathways. If the uncertain critical threshold were to be further away than previously considered, a pathway that may have been in danger of tipping, may no longer involve an overshoot at all. In our study, we highlight the need to constrain the highly uncertain diffusive timescale (representative of wind-driven fluxes) within the box model to reduce tipping uncertainty for overshoot scenarios of the AMOC.

Published: July 2024

Abstract. The Tibetan Plateau (TP) hosts a variety of vegetation types, ranging from broadleaved and needle-leaved forests at the lower altitudes and in mesic areas to alpine grassland at the higher altitudes and in xeric areas. Accurate and detailed mapping of the vegetation distribution on the TP is essential for an improved understanding of climate change effects on terrestrial ecosystems. Yet, existing land cover datasets for the TP are either provided at a low spatial resolution or have insufficient vegetation types to characterize certain unique TP ecosystems, such as the alpine scree. Here, we produced a 10 m resolution TP land cover map with 12 vegetation classes and 3 non-vegetation classes for the year 2022 (referred to as TP_LC10-2022) by leveraging state-of-the-art remote-sensing approaches including Sentinel-1 and Sentinel-2 imagery, environmental and topographic datasets, and four machine learning models using the Google Earth Engine platform. Our TP_LC10-2022 dataset achieved an overall classification accuracy of 86.5 % with a kappa coefficient of 0.854. Upon comparing it with four existing global land cover products, TP_LC10-2022 showed significant improvements in terms of reflecting local-scale vertical variations in the southeast TP region. Moreover, we found that alpine scree, which is ignored in existing land cover datasets, occupied 13.99 % of the TP region, and shrublands, which are characterized by distinct forms (deciduous shrublands and evergreen shrublands) that are largely determined by the topography and are missed in existing land cover datasets, occupied 4.63 % of the TP region. Our dataset provides a solid foundation for further analyses which need accurate delineation of these unique vegetation types in the TP. TP_LC10-2022 and the sample dataset are freely available at https://doi.org/10.5281/zenodo.8214981 (Huang et al., 2023a) and https://doi.org/10.5281/zenodo.8227942 (Huang et al., 2023b), respectively.

The Ross Sea and Amundsen Sea Ice-Sea Model (RAISE v1.0): a high-resolution ocean-sea ice-ice shelf coupling model for simulating the Dense Shelf Water and Antarctic Bottom Water in the Ross Sea, Antarctica
Authors: Zhang Zhaoru , Xie Chuan , Wang Chuning , Chen Yuanjie , Hu Heng , Wang Xiaoqiao
Published: July 2024

Abstract. The Ross Sea in the Southern Ocean is a key region for the formation of the Antarctic Bottom Water (AABW) that supplies the lower limb of the global overturning circulation, and contributes to 20–40 % of the total AABW production. AABW primarily originates from polynyas characterized by strong sea ice production and ocean convection that lead to the formation of Dense Shelf Water (DSW), the precursor of the AABW. The production and characteristics of DSW in the Ross Sea and AABW in the surrounding ocean are significantly affected by ice shelf meltwater transported from the nearby Amundsen Sea. The scarcity of long-term observations in the Ross Sea hinders the understanding of DSW and AABW variability, and numerical models are needed to explore the multi-scale variations of these water masses and the forcing mechanisms. In this work, a coupled high-resolution ocean-sea ice-ice shelf model is developed for the Ross Sea and Amundsen Sea, named RAISE (Ross-Amundsen Sea Ice-Sea Model). Detailed descriptions of the model configurations are provided. This study represents a first attempt to thoroughly evaluate the DSW properties and associated ocean-sea ice-ice shelf coupling processes among modelling studies in the Southern Ocean, using multiple datasets including satellite-based observations and hydrographic measurements from the World Ocean Database, Argo profilers and seal-tag sensors. In particular, the modelled temporal variations of DSW in polynyas and its key export passages are compared with long-term mooring observations, which are not seen in DSW studies before. RAISE demonstrates high skills in simulating the observed sea ice production rates in the Ross Sea polynyas, and the modelled spatial and temporal variability of DSW are significantly and strongly correlated with observations. RAISE can also effectively capture the observed long-term freshening trend of DSW prior to 2014 and the rebounding of DSW salinity after 2014. RAISE shows an overestimate of DSW density in the Ross Sea, which is associated with underestimate of ice shelf melting rates in the Amundsen Sea, missing ice shelf calving processes and subglacial discharge in the model. A sensitivity experiment simulating increased freshwater discharge from these processes can significantly improve the simulation of DSW properties.
Estuarine hurricane wind can intensify surge-dominated extreme water level in shallow and converging coastal systems

Published: July 2024

Abstract. Based on the projected increase in hurricane landfall frequency on the middle to lower US east coast, we examined the crucial role of the estuarine wind field in exacerbating coastal flooding. A regionally refined atmospheric and two high-resolution hydrology and ocean models are integrated to provide plausible and physically consistent ensembles of hurricane events and the associated flooding inside the Delaware Bay and River, a US mid-Atlantic estuary. Model results show that the hurricane propagation direction, estuarine geometry, remote surge from the open ocean, and direct nearshore upwind stress could magnify the flood magnitude. More specifically, inland-bound tracks that make landfall before reaching the mid-Atlantic coast produce a more significant surge within Delaware Bay than the shore-parallel tracks, where the estuarine wind direction plays the primary role in surge amplification. Ultimately, this study emphasized the need for integrated models to capture the nonlinear dynamics and interactions in flood hazard modeling.
Improving measurements of microbial growth, death, and turnover by accounting for extracellular DNA in soils
Authors: Schnecker Jörg , Böckle Theresa , Horak Julia , Martin Victoria , Sandén Taru , Spiegel Heide
Published: July 2024

Abstract. Microbial respiration, growth, and turnover are driving processes in the formation and decomposition of soil organic matter. In contrast to respiration and growth, microbial turnover and death currently lack distinct methods to be determined. Here we propose a new approach to determine microbial death rates and to improve measurements of microbial growth. By combining sequential DNA extraction to distinguish between intracellular and extracellular DNA and 18O incorporation into DNA, we were able to measure microbial death rates. We first evaluated methods to determine and extract intracellular and extracellular DNA separately. We then tested the method by subjecting soil from a temperate agricultural field and a deciduous beech forest to either 20, 30, or 45 °C for 24 h. Our results show that while mass-specific respiration and gross growth either increased with temperature or remained stable, microbial death rates strongly increased at 45 °C and caused a decrease in microbial biomass and thus in microbial net growth. We further found that also extracellular DNA pools decreased at 45 °C compared to lower temperatures, further indicating the enhanced uptake and recycling of extracellular DNA along with increased respiration, growth, and death rates. Additional experiments including soils from more and different ecosystems as well as testing the effects of factors other than temperature on microbial death are certainly necessary to better understand the role of microbial death in soil C cycling. We are nevertheless confident that this new approach to determine microbial death rates and dynamics of intracellular and extracellular DNA separately will help to improve concepts and models of C dynamics in soils in the future.
Widespread increase in discharge from west Antarctic Peninsula glaciers since 2018
Authors: Davison Benjamin J. , Hogg Anna E. , Moffat Carlos , Meredith Michael P. , Wallis Benjamin J.
Published: July 2024

Abstract. Many glaciers on the Antarctic Peninsula have retreated and accelerated in recent decades. Here we show that there has been a widespread, quasi-synchronous, and sustained increase in grounding line discharge from glaciers on the west coast of the Antarctic Peninsula since 2018. Overall, the west Antarctic Peninsula discharge trends increased by over a factor of 3, from 50 Mt yr−2 during 2017 to 2020 up to 160 Mt yr−2 in the years following, leading to a 7.4 % increase in grounding line discharge since 2017. The acceleration in discharge was concentrated at glaciers connected to deep, cross-shelf troughs hosting warm-ocean waters, and the acceleration occurred during a period of anomalously high subsurface water temperatures on the continental shelf. Given that many of the affected glaciers have retreated over the past several decades in response to ocean warming, thereby highlighting their sensitivity to ocean forcing, we argue that the recent period of anomalously warm water was likely a key driver of the observed acceleration. However, the acceleration also occurred during a time of anomalously high atmospheric temperatures and glacier surface runoff, which could have contributed to speed-up by directly increasing basal water pressure and, by invigorating near-glacier ocean circulation, increasing submarine melt rates. The spatial pattern of glacier acceleration therefore provides an indication of glaciers that are exposed to warm-ocean water at depth and/or have active surface-to-bed hydrological connections; however, many stages in the chain of events leading to glacier acceleration, and how that response is affected by glacier-specific factors, remain insufficiently understood. Both atmospheric and ocean temperatures in this region and its surroundings are likely to increase further in the coming decades; therefore, there is a pressing need to improve our understanding of recent changes in Antarctic Peninsula glacier dynamics in response atmospheric and oceanic changes in order to improve projections of their behaviour over the coming century.

Published: July 2024

The purpose of the article is to substantiate the possibility of selecting objects in the image generated by the technical vision system of an unmanned aerial vehicle by using structural and geometric features. This goal is achieved based on the analysis of the distribution of fractal dimension, which characterizes the structural properties of images, taking into account the object content, and the size of the area of the selection object. The solution to the first problem is based on the formation of histograms of fractal dimension depending on the number of objects in the image and identifying the features by which the object is selected. The solution to the second problem is based on developing an approach to reducing the object content of images by making it noisy. The noise parameters at which signs of object selection appear in the histograms of the distribution of fractal dimensions are determined. The range of fractal dimension defined. The solution to the third problem is based on specifying the selection object by its area. The most significant result is the identified values of fractal dimension ranges depending on the object content of the image, as well as experimentally established noise parameters to identify the necessary features in histograms of fractal dimensions. The significance of the work lies in solving the problem of selecting a reference object on images of heterogeneous object composition. This made it possible to significantly reduce the computational complexity of selecting objects in images.

On the question of metabolic prerequisites for disorders of glucose homeostasis in cows in the early period after calving
Authors: Vasileva S. V.
Published: July 2024

The article raises the problem of hyperglycemia in cows after calving and examines the frequency of its detection in the first two weeks after calving. The conducted studies made it possible to determine the frequency of detection of hypo- and hyperglycemia in livestock farms in the Leningrad region in connection with the content of beta-hydroxybutyric acid in the blood of cows. A high percentage of cases of hyperglycemia were detected on the 5th and 15th days after calving - 30.5% and 34.4%, while hypoglycemia was detected only in 16.8% and 12.1% of cases. Glucose concentrations within the standard ranges were determined in 48.9% of cows on the fifth and in 57.4% of cows on the fifteenth day of lactation. Betahydroxybutyrate concentrations are inversely related to blood glucose levels. In this case, hypoglycemia is accompanied by a significant increase in the content of ketones in the blood on days 5 and 15 of lactation by 2.25 and 2.44 times in comparison with cows with optimal blood glucose levels. With hyperglycemia, on the contrary, a significant decrease in the content of beta-hydroxybutyric acid is detected by 24.5 and 20.1%. The elevated level of glucose in the blood on the fifth day after calving in 51.7% of cows decreases by the fifteenth day, in 24.4% it increases, and in 23.9% it remains at the same level.

Published: July 2024

The article presents the results of a study conducted to evaluate the larvocidal effectiveness of macrocyclic lactones containing avermectins against reindeer edemagenosis. The spread of edemagenosis and the degree of infestation of reindeer by subcutaneous botfly larvae were studied by examining animals during the period of clinical manifestations of the disease (January-February), as well as by examining skins during the planned slaughter of deer. The extent of infestation by subcutaneous gadfly larvae was 6.9% for mature male, 16.4% for first time pregnant female, and 29.9% for mature female. The drug "Novomek 1%", containing ivermectin as an active ingredient, was used intramuscularly; “Aversect-2” containing aversectin C – subcutaneously; “Hypodectin N” (DV ivermectin) was applied along the back in a thin stream, spreading from the withers to the sacrum. Taking into account the timing of the summer of the imaginal stages of gadflies, the animals were treated once in the third ten days of September. It has been established that the parental route of administration of macrocyclic lactones for edemagenosis is preferable. After using a drug containing ivermectin intramuscularly, larvae were found in one choir, 2 heifers and 5 heifers. After subcutaneous injections of the drug containing aversectin, edemagen larvae were not found in the choirs, but were detected in one heifer and 3 heifers. In animals treated with a drug containing ivermectin by applying it to the skin along the back, larvae were found in 2 mature males, 4 first time pregnant female and 6 mature females. When examining the skins of all deer in the control group, O. tarandi larvae were detected. A drug containing ivermectin as an active ingredient, used intramuscularly, has a more pronounced larvocidal effect compared to a drug used externally. After subcutaneous application of a drug containing aversectin C, edemagen larvae were not detected in choruses, and in heifers and important heifers, the extent of invasion did not exceed 30%. Preparations from the group of macrocyclic lactones, regardless of the route of administration, did not have a 100% larvocidal effect on the larvae of the subcutaneous botfly O. tarandi when used once.

The material for the study was 4213 electronic medical histories of domestic animals, which had clinical signs of respiratory system pathologies, such as tachypnea, dyspnea, shortness of breath, medium and small bubbly wheezing, apathy, low tolerance to physical exertion. In the course of the study, it was found that symptoms of pneumonia of various etiologies were noted in 744 individuals or 17.61% of all animals with various pathologies of the respiratory system. Aspiration pneumonia was diagnosed in 183 animals, which is 24.59% of all patients with pneumonia or 4.34% of all animals diagnosed with respiratory apparatus pathology. Radiographs revealed that 91 animals (50%) have alveolar infiltrates in the lung tissue, 61 animals (33.3%) have an interstitial pattern. In 30 animals (16.6%), lung infiltration was represented by both alveolar and interstitial patterns. Of the 7 lung lobes: one lobe was affected in 95 animals (52%), two lung lobes were affected in 56 animals (31%), three lung lobes in 16 animals (9%), four lung lobes in 10 animals (5%), all 7 lobes were affected in three animals (1%). Taking into account the results obtained, the authors conclude that 50% of the studied animals had alveolar infiltrations in the lungs, 52% had only one lung lobe affected. The data obtained should be taken into account when diagnosing aspiration pneumonia in small pets.
Surgical treatment of corneal sequestration in cats

Published: July 2024

Surgical treatment of corneal sequestration in cats was performed in various ways. Treatment of corneal sequestration was carried out by such methods as superficial keratectomy followed by temporary tarzoraphy, layered keratectomy with closure of the defect using a flap on a pedicle from the palpebral conjunctiva and layered keratectomy followed by corneoscleral transposition. The results of the effectiveness of each surgical intervention method were described. Two out of three cases of corneal sequestration treatment by superficial keratectomy ended successfully, in one case the treatment ended unsuccessfully. Treatment of corneal sequestration by layered keratectomy followed by closure of the defect using a flap on a leg from the palpebral conjunctiva was successful, and treatment by layered keratectomy followed by corneoscleral transposition in one case was unsuccessful. The absence of a positive effect from surgery could be due to a violation of the instructions by the owners or the peculiarities of the regenerative process of the cornea of these patients.

The objective of this study was to assess the cause and effect relationship of value added tax (VAT) and Real gross domestic product (RGDP) in Tanzania. The study adopted quantitative descriptive design. This study used only secondary data collected from Tanzania Revenue Authority (TRA) from the year 2000 to 2021 and National Bureau of statistics (NBS). The time series data gathered were tested for stationarity and analyzed quantitatively through ordinary least square method by using Stata 14 statistical software. The findings indicated VAT [R 2 = 0.9867, Ln (RGDP) =12.21854+0.4133458ln (VAT)] significantly and positively contribute to country’s GDP. A number of recommendations were made from this study, Tanzania should intensify its efforts to collect VAT by providing more education to taxpayers, and improve consistency administration of VAT collection using EFD. It was also recommended TRA to enhance usage of electronic tax filing system in order to improve service delivery and foster accountability by closing off opportunities for revenue leakage and improve voluntary compliance. It was further recommended Policy makers in Tanzania to look on possibilities of reducing VAT rate to 16% so as to reduce distortion on social welfare.

This study examined the chemical characteristics, mineralogy, and grindability of copper ore from Anka-Brabra, Zamfara State, Nigeria. The ore was crushed, ground, and mixed to achieve a uniform sample. The ore sample was characterised using EDX-XRF, XRD, SEM, and petrological microscope. Grindability and fractional sieve analysis techniques were used to ascertain optimal grinding size through particle size distribution and the liberation size of the mineral. Results showed the main copper mineral was malachite (Cu2(CO3)(OH)2) with traces of other minerals. Analysis indicated a copper content of up to 20.2%. The ideal grinding size for liberation was determined to be 160 microns, with 53% of the ore particles reaching an acceptable size of 250 microns. The ore sample was characterised using EDX-XRF, XRD, SEM, and petrological microscope. Grindability and fractional sieve analysis techniques were used to ascertain optimal grinding size through particle size distribution and the liberation size of the mineral.
