Published: February 2023

Abstract. Low level stratiform clouds (LLSCs) covering a large area appear frequently during the wet monsoon season in southern West Africa. This region is also a place where different types of aerosols coexist, including biomass burning aerosols coming from Central and South Africa and anthropogenic aerosols emitted from local activities. We investigate the semi-direct and indirect effects of these aerosols on the diurnal cycle of LLSCs by constructing a case study based on airborne and ground-based observations from the Dynamic-Aerosol-Chemistry-Cloud-Interaction in West Africa (DACCIWA) field campaign. This case is modelled using a Large Eddy Simulation (LES) model with fine scale resolution and in-situ aerosol measurements including size distribution and chemical composition. The model has successfully reproduced the observed life cycle of the LLSC, from stratus formation to stabilization during the night, to upward development after sunrise until breakup of cloud deck in late afternoon. Various sensitivity simulations using different measured aerosol profiles also suggest that aerosols can affect the cloud life cycle through both the indirect and semi-direct effect. Despite precipitation produced by the modeled cloud is nearly negligible, cloud lifetime is still sensitive to the aerosol concentration. As expected, modeled cloud microphysical features including cloud droplet number concentration, mean radius, and thus cloud reflectivity are all controlled by aerosol concentration. However, it is found that the difference in cloud reflectivity is not always the only factor in determining the variation of the incoming solar radiation at ground and cloud life cycle specifically beyond sunrise. Instead, the difference in cloud-void space brought by dry air entrainment from above and thus the speed of consequent evaporation – also influenced by aerosol concentration, is another important factor to consider. Results have shown that clouds in the case with lower aerosol concentration and larger droplet size appear to be less affected by entrainment and convection. In addition, we have found that an excessive atmospheric heating up to 12 K day−1 produced by absorbing black carbon aerosols (BC) in our modeled cases can also affect the life cycle of modeled clouds. Such a heating is found to lower the height of cloud top and stabilize the cloud layer, resulting a less extent in vertical development and accelerating cloud breakup. The semi-direct effect impacts on indirect effect by reducing cloud reflectivity particularly in case of polluted environment. Finally, semi-direct effect is found to contribute positively to the indirect radiative forcing due to a decreased cloud-void space, and negatively by causing thinner clouds that would break-up faster in late afternoon, all depending on the phase in stratiform cloud diurnal cycle.

Abstract. The number of cloud droplets per unit volume (Nd) is a
fundamentally important property of marine boundary layer (MBL) liquid
clouds that, at constant liquid water path, exerts considerable controls on
albedo. Past work has shown that regional Nd has a direct correlation to
marine primary productivity (PP) because of the role of seasonally varying,
biogenically derived precursor gases in modulating secondary aerosol
properties. These linkages are thought to be observable over the high-latitude oceans, where strong seasonal variability in aerosol and meteorology
covary in mostly pristine environments. Here, we examine Nd variability
derived from 5 years of MODIS Level 2-derived cloud properties in a broad
region of the summer eastern Southern Ocean and adjacent marginal seas. We
demonstrate latitudinal, longitudinal and temporal gradients in Nd that
are strongly correlated with the passage of air masses over high-PP waters
that are mostly concentrated along the Antarctic Shelf poleward of
60∘ S. We find that the albedo of MBL clouds in the latitudes
south of 60∘ S is significantly higher than similar liquid water path (LWP) clouds
north of this latitude.
Mammalian bioturbation amplifies rates of both, hillslope sediment erosion and accumulation, in coastal Chile

Published: February 2023

Abstract. Soil bioturbation activity affects soil texture, bulk density, soil water content and redistribution of nutrients. All of these parameters influences sediment redistribution, which shapes the earth surface. Hence it is important to include bioturbation into erosion models. However, up to present, the inclusion of bioturbation into erosion models was limited. This is because to realistically include bioturbation into the modelling, the interplay between bioturbation, sediment redistribution and environmental parameters is not understood. Here, we included bioturbation into a soil erosion model and interpreted the impacts of bioturbation on sediment redistribution. To do this, we measured the needed soil properties and location of burrows created by bioturbating animals in four research sites located along the Chilean climate gradient. Then, we parametrized a semi-empirical erosion model by applying machine learning algorithms to upscale soil properties and burrow distribution. We ran the model for a time period of 6 years under two conditions: With and without bioturbation. We validated the model using several sediment fences in the field. We estimated the modelled sediment redistribution and surface runoff in all climate zones. Lastly, we identified environmental parameters determining the positive or negative impact of bioturbation on sediment redistribution. We found that the model with integrated bioturbation performed much better (R2 = 0.71, RMSE = 0.63) than the model without integrated bioturbation (R2 = 0.17, RMSE = 1.18), meaning that model runs which considered bioturbation predicted the sediment redistribution more realistically. Furthermore, bioturbation increased sediment redistribution in all but the humid climate zone, especially in the Mediterranean zone. The quantity of sediment redistributed due to bioturbation was reliant on an interplay between elevation, slope, surface roughness and sink connectivity. Overall, bioturbation enhances sediment erosion in areas where more erosion is expected, and enhances sediment accumulation in areas which are more prone to accumulate sediment. In other words, considering bioturbation when studying earth surface evolution means an amplification of existing tendencies in sediment redistribution, and leads to a faster hillslope relief equalisation.
Reconstructions and predictions of the global carbon budget with an emission-driven Earth system model

Published: February 2023

Abstract. The global carbon budget (GCB) – including fluxes of CO2 between the atmosphere, land, and ocean and its atmospheric growth rate – show large interannual to decadal variations. Reconstructing and predicting the variable GCB is essential for tracing the fate of carbon and understanding the global carbon cycle in a changing climate. We use a novel approach to reconstruct and predict the variations in GCB in the next few years based on our decadal prediction system enhanced with an interactive carbon cycle. By assimilating physical atmospheric and oceanic data products into the Max Planck Institute Earth System Model (MPI-ESM), we are able to reproduce the annual mean historical GCB variations from 1970–2018, with high correlations of 0.75, 0.75, and 0.97 for atmospheric CO2 growth, air–land CO2 fluxes, and air–sea CO2 fluxes, respectively, relative to the assessments from the Global Carbon Project (GCP). Such a fully coupled decadal prediction system, with an interactive carbon cycle, enables the representation of the GCB within a closed Earth system and therefore provides an additional line of evidence for the ongoing assessments of the anthropogenic GCB. Retrospective predictions initialized from the simulation in which physical atmospheric and oceanic data products are assimilated show high confidence in predicting the following year's GCB. The predictive skill is up to 5 years for the air–sea CO2 fluxes, and 2 years for the air–land CO2 fluxes and atmospheric carbon growth rate. This is the first study investigating the GCB variations and predictions with an emission-driven prediction system. Such a system also enables the reconstruction of the past and prediction of the evolution of near-future atmospheric CO2 concentration changes. The Earth system predictions in this study provide valuable inputs for understanding the global carbon cycle and informing climate-relevant policy.

Abstract. Seagrass meadows provide valuable socio-ecological ecosystem
services, including a key role in climate change mitigation and adaption.
Understanding the natural history of seagrass meadows across environmental
gradients is crucial to deciphering the role of seagrasses in the global ocean.
In this data collation, spatial and temporal patterns in seagrass meadow
structure, biomass and production data are presented as a function of biotic
and abiotic habitat characteristics. The biological traits compiled include
measures of meadow structure (e.g. percent cover and shoot density),
biomass (e.g. above-ground biomass) and production (e.g. shoot
production). Categorical factors include bioregion, geotype (coastal or
estuarine), genera and year of sampling. This dataset contains data
extracted from peer-reviewed publications published between 1975 and 2020
based on a Web of Science search and includes 11 data variables across 12
seagrass genera. The dataset excludes data from mesocosm and field
experiments, contains 14 271 data points extracted from 390 publications
and is publicly available on the PANGAEA® data repository
(https://doi.org/10.1594/PANGAEA.929968; Strydom et al., 2021). The top five most studied genera are Zostera, Thalassia, Cymodocea, Halodule and Halophila (84 % of data), and the least studied genera
are Phyllospadix, Amphibolis and Thalassodendron (2.3 % of data). The data hotspot bioregion is the Tropical
Indo-Pacific (25 % of data) followed by the Tropical Atlantic (21 %),
whereas data for the other four bioregions are evenly spread (ranging
between 13 and 15 % of total data within each bioregion). From the data
compiled, 57 % related to seagrass biomass and 33 % to seagrass
structure, while the least number of data were related to seagrass
production (11 % of data). This data collation can inform several research
fields beyond seagrass ecology, such as the development of nature-based
solutions for climate change mitigation, which include readership interested
in blue carbon, engineering, fisheries, global change, conservation and
policy.

Abstract. The Atlantic Zone Monitoring Program (AZMP) was established by Fisheries and Oceans Canada (DFO) in 1998 with the aim of monitoring physical and biological ocean conditions in Atlantic Canada in support of fisheries management. Since 2014, at least two of the carbonate parameters (pH, Total Alkalinity - TA, Dissolved Inorganic Carbon - DIC) have also been systematically measured as part of the AZMP, enabling the calculation of derived parameters (e.g., carbonate saturation states - Ω, partial pressure of CO2 - pCO2, etc.). The present study gives an overview of the spatiotemporal variability of these parameters between 2014 and 2020. Results show that the variability of carbonate parameters reflects changes in both physical (e.g., temperature, salinity) and biological (e.g., plankton photosynthesis and respiration) parameters. For example, most of the region undergoes a seasonal warming and freshening. While the former will tend to increase Ω, the latter will decrease both TA and Ω. Spring and summer plankton blooms decrease DIC near the surface and then remineralize and increase DIC at depth in the fall. The lowest pCO2 values are located in the cold Coastal Labrador Current and the highest in the fresh waters of the Gulf of St. Lawrence and the St. Lawrence Estuary. The latter is also the host of the lowest pH values of the zone. Finally, most of the bottom waters of the Gulf of St. Lawrence are undersaturated with respect to aragonite (Ωarg<1). In addition to providing a baseline of carbonate parameters of the Atlantic Zone as a whole, this comprehensive overview is a necessary and useful contribution for the modeling community and for more in-depth studies. The full data set of measured and derived parameters is available in the Federated Research Data Repository at https://doi.org/10.20383/102.0673.
Climate sensitivity of the summer runoff of two glacierised Himalayan catchments with contrasting climate
Authors: Laha Sourav , Banerjee Argha , Singh Ajit , Sharma Parmanand , Thamban Meloth
Published: February 2023

Abstract. The future changes in runoff of Himalayan glacierised catchments will be determined by the local climate forcing and the climate sensitivity of the runoff. Here, we investigate the sensitivity of summer runoff to precipitation and temperature changes in the winter-snow-dominated Chandra (the western Himalaya) and summer-rain-dominated upper Dudhkoshi (the eastern Himalaya) catchments. We analyse the interannual variability of summer runoff in these catchments during 1980–2018 using a semi-distributed glacio–hydrological model, which is calibrated with the available runoff and glacier mass-balance observations. Our results indicate that despite the contrasting precipitation regimes, the catchments have a similar runoff response: the summer runoff from the glacierised parts of both catchments is sensitive to temperature changes and insensitive to precipitation changes; the summer runoff from the non-glacierised parts of the catchments has the exact opposite pattern of sensitivity. The precipitation-independent glacier contribution stabilises the catchment runoff against precipitation variability to some degree. The estimated sensitivities capture the characteristic “peak water” in the long-term mean summer runoff, which is caused by the excess meltwater released by the shrinking ice reserve. As the glacier cover depletes, the summer runoff is expected to become more sensitive to precipitation forcing in these catchments. However, the net impact of the glacier loss on the catchment runoff may not be detectable, given the relatively large interannual runoff variability in these catchments.
Characterizing the rate of spread of large wildfires in emerging fire environments of northwestern Europe using Visible Infrared Imaging Radiometer Suite active fire data

Published: February 2023

Abstract. In recent years fires of greater magnitude have been documented
throughout northwest Europe. With several climate projections indicating
future increases in fire activity in this temperate area, it is imperative
to identify the status of fire in this region. This study unravels unknowns
about the state of the fire regime in northwest Europe by characterizing one
of the key aspects of fire behavior, the rate of spread (ROS). Using an
innovative approach to cluster Visible Infrared Imaging Radiometer Suite (VIIRS) hotspots into fire perimeter isochrones
to derive ROS, we identify the effects of land cover and season on the rate
of spread of 102 landscape fires that occurred between 2012 and 2022.
Results reveal significant differences between land cover types, and there
is a clear peak of ROS and burned area in the months of March and April.
Median ROS within these peak months is approximately 0.09 km h−1 during a
12 h overpass, and 66 % of the burned area occurs in this spring
period. Heightened ROS and burned area values persist in the bordering
months of February and May, suggesting that these months may present the
extent of the main fire season in northwest Europe. Accurate data on ROS
among the represented land cover types, as well as periods of peak activity,
are essential for determining periods of elevated fire risk, the
effectiveness of available suppression techniques, and appropriate
mitigation strategies (land and fuel management).
Investigation of the effects of surrounding media on the distributed acoustic sensing of a helically wound fibre-optic cable with application to the New Afton deposit, British Columbia

Published: February 2023

Abstract. Fibre-optic sensing technology has recently become popular for oil
and gas extraction, mining, geotechnical engineering, and hydrogeology applications.
With a successful track record in many applications, distributed acoustic
sensing using straight fibre-optic cables has become a method of choice for
seismic studies. However, distributed acoustic sensing using straight fibre-optic cables cannot detect off-axial strain at high incident angles (the
angle between the ray and normal vector of the surface); hence, a helically
wound cable design was introduced to overcome this limitation. The helically
wound cable field data at the New Afton deposit in British Columbia, Canada,
showed that the quality of the data is highly dependent on the incident
angle and surrounding media. A 3D finite element model developed using
COMSOL Multiphysics quickly and efficiently assessed the effects of various
materials surrounding a helically wound cable for simple geometry for
scenarios corresponding to a real deployment of such cable underground at
the New Afton mine. The proposed numerical modelling workflow could be
applied to more complicated scenarios (e.g., non-linear material
constitutive behaviour and the effects of pore fluids). The results of this
paper can be used as a guideline for analyzing the impact of surrounding
media and incident angle on the response of helically wound cable,
optimizing the installation of helically wound cable in various conditions,
and validating boundary conditions of 3D numerical models built for
analyzing complex scenarios.
Megadunes in Antarctica: migration and characterization from remote and in situ observations
Authors: Traversa Giacomo , Fugazza Davide , Frezzotti Massimo
Published: February 2023

Abstract. Megadunes are peculiar features formed by the interaction between
the atmosphere and cryosphere and are known to be present only on the East
Antarctic Plateau and other planets (Mars and Pluto). In this study, we have
analysed the glaciological dynamic of megadunes, their spectral properties
and morphology on two sample areas of the East Antarctic Plateau where in
the past international field activities were carried out (EAIIST, East Antarctic International Ice Sheet Traverse;
It-ITASE, Italian International Trans-Antarctic Scientific Expedition). Using satellite images spanning 7 years, we analysed the spatial
and temporal variability in megadune surface characteristics, i.e. near-infrared (NIR) albedo, thermal brightness temperature (BT) and slope along
the prevailing wind direction (SPWD), useful for mapping them. These
parameters allowed us to characterize and perform an automated detection of
the glazed surfaces, and we determined the influence of the SPWD by
evaluating different combinations of these parameters. The inclusion of the
SPWD significantly increased the accuracy of the method, doubling it in
certain analysed scenes. Using remote and field observations, for the first
time we surveyed all the components of upwind migration (absolute,
sedimentological and ice flow), finding an absolute value of about 10 m a−1. The analysis shows that the migration is driven by the snow
accumulation on the crest and trough prograding upwind on the previous
windward flanks characterized by glazed surface. Our results present
significant implications for the surface mass balance estimation, paleo-climate
reconstruction using ice cores, and the measurements using optical and
radar images/data in the megadune areas.
Mass changes of the northern Antarctic Peninsula Ice Sheet derived from repeat bi-static SAR acquisitions for the period 2013–2017
Authors: Seehaus Thorsten Christian , Sommer Christian , Dethinne Thomas , Malz Philipp
Published: February 2023

Abstract. Some of the highest specific mass change rates in Antarctica are reported for the Antarctic Peninsula. However, the existing estimates for the northern Antarctic Peninsula (< 70° S) are either spatially limited or are affected by considerable uncertainties. The complex topography, frequent cloud cover, limitations in ice thickness information, boundary effects, and uncertain glacial-isostatic adjustment estimates affect the ice sheet mass change estimates using altimetry, gravimetry, or the input-output method. Within this study, the first assessment of the geodetic mass balance throughout the ice sheet of the northern Antarctic Peninsula is carried out employing bi-static SAR data from the TanDEM-X satellite mission. Repeat coverages from austral-winters 2013 and 2017 are employed. An overall coverage of 96.4 % of the study area by surface elevation change measurements and a total mass budget of −24.1 ± 2.8 Gt/a is revealed. The spatial distribution of the surface elevation and mass changes points out, that the former ice shelf tributary glaciers of the Prince-Gustav-Channel, Larsen-A&B, and Wordie ice shelves are the hotpots of ice loss in the study area, and highlights the long-lasting dynamic glacier adjustments after the ice shelf break-up events. The highest mass change rate is revealed for the Airy-Seller-Fleming glacier system of −4.9 ± 0.6 Gt/a and the highest average surface elevation change rate of −2.30 ± 0.03 m/a is observed at Drygalski Glacier. The comparison of the ice mass budget with anomalies in the climatic mass balance indicates, that for wide parts of the southern section of the study area, the mass changes can be partly attributed to changes in the climatic mass balance. However, imbalanced high ice discharge drives the overall ice loss. The previously reported connection between mid-ocean warming along the southern section of the west coast and increased frontal glacier recession does not repeat in the pattern of the observed glacier mass losses, excluding Wordie Bay. The obtained results provide information on ice surface elevation and mass changes for the entire northern Antarctic Peninsula on unprecedented spatially detailed scales and high precision and will be beneficial for subsequent analysis and modeling.
Temporal and spatial variability of air temperature and precipitation at the Polish coastal zone of the southern Baltic Sea
Authors: Tylkowski Jacek
Published: February 2023

The study concerns the analysis of temporal and spatial variability of thermal and precipitation conditions at the Polish Baltic coastal zone in the second half of the twentieth century and the first decade of the twenty–first century. The paper also presents its annual and daily extreme values of air temperature and precipitation. The study area includes the Polish coast of the Baltic Sea at which long–term measurements and observations of weather conditions have been performed within the national meteorological services at seven Baltic coastal stations. Their daily data of air temperature and precipitation taken from the measuring period of 1966–2009 were used in the study. For each meteorological station was set thresholds of annual average air temperature and annual total precipitation. Temporal variability of air temperature was determined by the thermal classification made by Lorenc (1998). Temporal variability of precipitation was determined by the precipitation classification made by Kaczorowska (1998).
The ‘chicken-egg-model’: a simple in vitro model for 3D-ultrasonography and elastography
Authors: Vanthienen M , Dewilde K , Van den Bosch T
Published: February 2023

Background: Three-dimensional ultrasound (3D-ultrasound) and elastography are imaging techniques facilitating the diagnosis of gynaecological diseases and uterine anomalies. These non-invasive ultrasound applications may be of important added diagnostic value in gynaecological ultrasonography.

Objectives: The main objective of this study was to develop a simple and cheap in vitro model for elastography and 3D-ultrasound, with an adaptable probe-target distance. The target should be visible within the model and its hardness should be modifiable. The orientation and inclination of the model should also be adjustable.

Materials and Methods: We used a boiled chicken egg in a gel basis as this mimics the elastic properties of human tissues. Different boiling times were compared with the stiffness at elastography. Both 3D-ultrasonography and strain elastography were conducted with a Voluson™ E10 4-9 MHz vaginal probe.

Results: Altering the eggs’ boiling times modulates the levels of stiffness, and hence the aspect on elastography.

Conclusions: Our model can help trainees to practice acquisition and interpretation of elastography images. This cheap and easy-to-reproduce, in vitro “chicken-egg-model” allows for education and training of 3D-ultrasound and elastography, without causing discomfort to patients.

What’s new? We created a cheap and easy to reproduce in vitro model for the education of 3D-ultrasound and elastography.

Authors: Usta T , Gonenc M , Yilmaz S , Akyol G.S.C. , Kale A , Oral E
Published: February 2023

Background: 10% of women of reproductive age are affected by endometriosis, and diaphragmatic endometriosis represents 1-1.5% of these cases. Diaphragmatic endometriotic lesions often require surgical treatment.

Objectives: This video aims to demonstrate the appearance of diaphragmatic endometriosis and describe our experience with robot-assisted laparoscopic excision of full thickness diaphragmatic endometriosis.

Materials and Methods: The patient was a 37-year-old female with the complaint of cyclical right shoulder pain (for 1 year). She previously had caesarean section scar and umbilical endometriosis excision procedures. The magnetic resonance imaging (MRI) of the abdomen highlighted three endometriotic nodules, one of which was described as full thickness on the right hemi-diaphragm. The patient underwent a robot-assisted laparoscopic endometriosis surgery as a joint procedure between the gynaecology and general surgery teams. The falciform ligament was completely divided to obtain full views of the endometriotic lesions on the diaphragm. Superficial diaphragmatic lesions were first excised. The larger deep nodule, which was described on the MRI, was then excised with the full thickness of diaphragm. Pleural cavity was entered intentionally to achieve complete excision of the nodule. Laparoscopic assessment of the right lower pleural cavity through this opening did not show any endometriotic lesions. After the excision, the diaphragm was repaired with a barbed suture. Negative pressure suction of the pleural cavity was performed at the end of this repair instead of using a chest tube.

Results: The patient was discharged on the 3rd day with no complications encountered. Histopathological examination confirmed endometriosis. The patient was asymptomatic three months after surgery.

Conclusion: Robotic-assisted surgery is an easy and safe choice especially in such challenging dual compartment surgeries by providing a 3D view that abolishes sensory loss and increases depth perception, providing better manoeuvrability with tremor absence.

Published: February 2023

A composite is one of the materials that is a mixture of two or more materials to form a third, more useful material. In this study, researchers chose bamboo fiber and iron sand as reinforcement for composite materials because the selection of bamboo fiber as a research material took into account the potential of bamboo fiber in Indonesia which is abundant and has not been utilized properly. The purpose of making bamboo fibrous composite materials aims to find a material that is lighter stronger and more elastic, can be developed into other products such as the manufacture of drone frames, aircraft bodies, brake pads. The method used is an experiment with making specimens using the hand lay up method and testing using impact testing and micro photo testing. Impact testing is used to determine the properties and characteristics of the material in the form of strength, hardness, and ductility of the material while for micro photos it is used to determine the bond of the material composition with the best impact test. The test standards used are ASTM D6110-10 with random fiber arrangement and ASTM D6110-04 with the arrangement of woven fibers, with variations in volume composition of bamboo fiber and iron sand particles. In the D6110-10 specimens, the best specimens were found in the variation with the most bamboo fibers, namely 35S10 P with an impact energy of 4.27 J and an impact price of 0.04 J / mm2, while the lowest variation was found in the most iron sand, namely 35P10S with an impact energy value of 2.26 J and an impact price of 0.02 J / mm2. In the D6110-04 specimen also showed the same characteristics as the ASTM D6110-10 specimen, the 30S30P variation or the composition of the most bamboo fibers had an impact energy value of 4.09 J while in the 10S10P variation it was only 1.47 J. Thus the more bamboo fibers will make the impact strength of the specimen higher.

On the seedling origin factor, the B2 treatment was the highest in terms of the observed parameters of shoot height and number of leaves. In the ZPT gibberellin concentration factor, it was shown that factor A1 was the highest in the observed variable of shoot height 20 dap (days after planting), while in the variable number of leaves 50 dap, factors A4 and A5 had the highest number of leaves. The interaction of seed origin and gibberellin concentrations showed that factor B1A4 had the highest shoot height at 20 dap observations, while B1A5 had the highest number of leaves at 40 and 50 dap observations.

Қандағы глюкоза деңгейінің тұрақсыз болуы адамда қант диабеті, қатерлі ісік, бүйрек және жүрек ауруларын тудырады. Адам өмірі жүректің дұрыс жұмыс жасауымен, жүрек соғысының тұрақтылығымен тікелей байланысты. Ал жүрек қызметін тұрақты бақылау қатерлі аурулармен ауыратын адамдар үшін маңызды. Қандағы глюкоза деңгейі жүрек қызметінің бұзылуына әкелуіне байланысты глюкоза деңгейін тұрақты бақылап отыру қажет. Глюкоза деңгейін инвазивті түрде, саусаққа ине сұғу арқылы анықтау үздіксіз анықтауға мүмкіндік бермеуі, науқас үшін ауыр және инфекцияға ұшырату мүмкіндігінің болуына байланысты инвазивті емес анықтаудың тиімді әдісін жетілдіру маңызды. Бұл мақалада қандағы глюкозаның деңгейіне байланысты жүрек қызметінің өзгерістерін анықтау үшін инвазивті емес әдіс ЭКГ арқылы анықтау қолданылды. ЭКГ арқылы қандағы глюкоза деңгейін анықтауға байланысты әдістер мен зерттеулерге және нәтижелерге талдау жасалынды. Зерттеу барысында ЭКГ арқылы анықтау үшін 5 сау қатысушыға екі күн бойы эксперимент жүргізілді. Бірінші күні қатысушылар  75 г сусыз глюкоза ерітіндісін тұтынса, екінші күні қатысушылар сусыз глюкоза ерітіндісін тұтынған жоқ. Екі күн бойы жүргізілген зерттеулер нәтижесі бойынша сау адамдар сусыз глюкоза ерітіндісін тұтынған жағдайда қандағы глюкоза деңгейінің өзгеретіндігі және ЭКГ нәтижелеріне әсер ететіндігі анықталды. ЭКГ нәтижелері мен глюкометрмен алынған нәтижелердің ұқсастығы мен айырмашылығы салыстырмалы түрде зерттелді. Зерттеу нәтижесі бойынша қандағы глюкозаның деңгейіне байланысты өзгеріске ұшырайтын ЭКГ аралықтары анықталды.

В статье представлены результаты экспериментальных исследовании проводимые на новой конструкции горелочного устройство с треугольными стабилизаторами при различных вариантах подачи топлива. При выполнении исследовании расход воздуха был постоянным, а скорость воздуха и расход топлива были переменными. Эксперименты проводились при различных вариантах расположения отверстия для подачи топлива. В результате представлены графики зависимости оксидов азота, температуры уходящих газов. Как показали эксперименты, треугольники с равномерной подачей топлива вдоль высоты являются наиболее эффективными с точки зрения образования оксидов азота. К примеру, наличие 16 отверстий при всех прочих равных условиях позволяют сократить образование оксидов азота на 29 %, что говорит о высокой эффективности перемешивания топлива с воздухом, что сокращает время нахождения газов в зоне высоких температур, а также локальные зоны высоких температур.
Научная новизна проводимых исследований заключается в исследовании новых микрофакельных горелок, которые могут применяться в нефтегазовой и металлургической областях. В отличие от предыдущих разработок, новые типы горелок отличаются тем, что топливо не попадает в рециркуляционную зону, а догорает в хвостовой части уголков, а также тем, что топливо подается в рециркуляционную зону, не перемешиваясь с воздухом.

В статье рассматривается актуальный вопрос обогащения биогаза водородом для сжигания в дизельном двигателе. Для Казахстана данная проблема пришла в последние 20 лет, так как ежегодно идет повышение стоимости дизельного топлива или его нехватки к осени во время сбора урожая. Возможности эффективного сжигания водорода в парниковых двигателях были известны еще во время блокады Ленинграда. Здесь мы обращаем внимание, что сжигание в дизельном двигателе богатого водородом биогаза и дизельного топлива повышает эффективность дизеля и снижает ее воздействие на окружающую среду. Так как имеются  доступные публикаций, то и наши исследования будут полезны. Результаты дальнейших исследований будут опубликованы в данном Вестнике.
