Abstract. Low-level (cloud tops below 2 km) mixed-phase clouds are important in amplifying warming in the Arctic region through positive feedback in cloud fraction, water content and phase. In order to understand the cloud feedbacks in the Arctic region, good knowledge of the vertical distribution of the cloud water content, particle size and phase is required. Here we present seven in-situ vertical profiles of cloud microphysical and optical properties measured in the European Arctic during the ACLOUD campaign. Late spring- and summer-time stratiform clouds were sampled over pack ice, marginal sea ice zone and open ocean surface with cloud top temperatures varying between −15 and −1.5 °C. The results show that, although liquid phase dominates the upper parts of the clouds, ice phase was frequently observed in the lower parts down to cloud top temperatures as warm as −3.8 °C. In the studied vertical cloud profiles the average liquid phase microphysical properties, droplet number concentration, effective radius and liquid water content, varied between 22 and 120 cm−3, 16 and 27 μm, 0.09 and 0.48 gm−3, respectively. The average ice phase microphysical properties, ice number concentration, effective radius and ice water content, varied between 0.01 and 35 L−1, 24 and 75 μm, 0.003 and 0.08 gm−3, respectively. The elevated ice crystal number concentrations and ice water paths observed for clouds with cloud top temperatures between −3.8 and −8.7 °C can be likely attributed to secondary ice production through rime-splintering. Low asymmetry parameters between 0.69 and 0.76 were measured for the mixed-phase ice crystals with a mean asymmetry parameter of 0.72. The effect of the ice phase for radiative transfer was investigated for the four cloud cases potentially affected by secondary ice production. Generally the ice phase has only a minor effect to the cloud transmissivity and albedo, except in a case where ice phase dominated the upper cloud layer extinction. In this case cloud albedo was increased by 10 %. The presented results highlight the importance of accurate vertical information of cloud phase for radiative transfer and provide a suitable data set for testing microphysical parameterisations in models.

Published: January 2023

Abstract. Simulation tools are important to investigate and predict mobility and the destructive potential of gravitational mass flows (e.g. snow avalanches). AvaFrame – the open avalanche framework – offers well established computational modeling approaches, tools for data handling and analysis as well as ready to use modules for evaluation and testing. This paper presents the theoretical background, derivation and model verification for one of AvaFrame’s core modules, the thickness integrated computational model for dense flow avalanches, named com1DFA. Particular emphasis within the description of the utilized numerical particle grid method is given to the computation of spatial gradients and the accurate implementation of driving and resisting forces. The implemented method allows to provide a time-space criterion connecting the numerical particles, grid and time discretization. The convergence and robustness of the numerical implementation is checked with respect to the spatio-temporal evolution of the flow variables using tests with a known analytical solution. In addition we present a new test for verifying the accuracy of the numerical simulation in terms of runout (angle and distance). This test is derived from the total energy balance along the center of mass path of the avalanche. This manuscript, particularly in combination with the code availability (open-source code repository) and detailed online documentation provides a description of an extendable framework for modeling and verification of avalanche simulation tools.
Precipitation reconstructions for Paris based on the observations of Louis Morin, 1665–1713 CE
Authors: Pliemon Thomas , Foelsche Ulrich , Rohr Christian , Pfister Christian
Published: January 2023

Abstract. This paper presents a precipitation reconstruction that is based on the continuous observations by Louis Morin in Paris from 1665–1713. Morin usually recorded precipitation intensity and duration, when it snowed/rained, three times each day (sometimes up to six times). The consistency of his observations can be calculated from his other measurements and observations (e.g. temperature, cloud cover), where at least one entry of his different measurements and observations for 98.7 % of all days is noted. To 5 convert these observations to common units, we calibrated them with a multiplicative interacting model using Philippe and Gabriele-Philippe de la Hire’s instrumental measurements from Paris. The two series of measurements by de la Hire (father and son) and observations by Morin overlap from 1688–1713. To test the quality of the reconstruction, we analyzed it with the de la Hire’s measurements, proxy data, an internal analysis of Morin’s measurements of different climate variables, and modern data. Thus, we assess the reliability of the precipitation reconstructions based on Morin’s data as follows. We have moderate confidence regarding the exact quantities of daily, seasonal, and annual precipitation totals. We have low confidence regarding exceptionally high precipitation amounts, but we have high confidence in the indices of an impact analysis (i.e., dry days, wet days, consecutive dry days, consecutive wet days), in monthly frequencies of rainfall, and in interannual, interseasonal, and interdecadal variability. Rainy seasons with precipitation totals greater than 250 mm occurred in MAM 1682, JJA 1682, SON 1687, JJA 1697 and JJA 1703. Furthermore, compared to other DJF seasons, the winter of 1666/67 stands out with a precipitation total of 248 mm. Dry seasons with precipitation totals less than 60 mm occurred in SON 1669, DJF 1690/91 and DJF 1693/94. An impact analysis shows no abnormalities regarding consecutive dry days or wet days in MAM. In JJA a longer dry period of 31 days appeared in 1686 and a dry period of 69 days appeared in DJF 1671/72.
Spaceborne thermal infrared observations of Arctic sea ice leads at 30 m resolution
Authors: Qiu Yujia , Li Xiao-Ming , Guo Huadong
Published: January 2023

Abstract. Sea ice leads are elongated fractures within sea ice cover, playing an important role in the heat exchange from the ocean to the overlying atmosphere. Narrow leads less than a hundred meters in width contribute considerable heat fluxes, requiring fine-scale observation of Arctic leads. With the launch of Sustainable Development Science Satellite 1 (SDGSAT-1) by China on 5 November 2021, the on-board Thermal Infrared Spectrometer (TIS) provides thermal infrared imagery at an unprecedented resolution of 30 m in a swath of 300 km. We propose a method adapted to the TIS high-resolution infrared images for lead detection in the Arctic. For the first time, the spatial resolution of leads by infrared remote sensing increases from the scale of kilometers to tens of meters. For the Beaufort Sea cases in April 2022, the detection is consistent with the Sentinel-2 visible images, yielding an overall accuracy of 96.30 %. Compared with the Moderate-Resolution Imaging Spectroradiometer (MODIS), the TIS presents more leads with width less hundreds of meters than the results based on the MODIS data. For the three infrared bands of the TIS, the B2 (10.3–11.3 µm) and B3 (11.5–12.5 µm) bands, show similar performances in detecting leads. The B1 band (8.0–10.5 µm) can be complementary to the other two bands, as the temperature measurement sensitivity is different from the other two, benefiting better detection by combining the three bands. This study demonstrates that SDGSAT-1 TIS data at 30 m resolution is well applicable for observing previously unresolvable ice leads, and will provide insight into the contribution of narrow leads to rapid sea ice changes in the Arctic.

Abstract. There is a temporal correlation between the peak activity of the North Atlantic Igneous Province (NAIP) and the Paleocene–Eocene Thermal Maximum (PETM), suggesting that the NAIP may have initiated and/or prolonged this extreme warming event. However, corroborating a causal relationship is hampered by a scarcity of expanded sedimentary records that contain both climatic and volcanic proxies. One locality hosting such a record is Fur Island in Denmark, where an expanded pre- to post-PETM succession containing hundreds of NAIP ash layers is exceptionally well preserved. We compiled a range of environmental proxies, including mercury (Hg) anomalies, paleotemperature proxies, and lithium (Li) and osmium (Os) isotopes, to trace NAIP activity, hydrological changes, weathering, and seawater connectivity across this interval. Volcanic proxies suggest that NAIP activity was elevated before the PETM and appears to have peaked during the body of the δ13C excursion, but decreased considerably during the PETM recovery. This suggests that the acme in NAIP activity, dominated by flood basalt volcanism and thermogenic degassing from contact metamorphism, was likely confined to just ~200 kyr (ca. 56.0–55.8 Ma). The hundreds of thick basaltic ashes in the post-PETM strata likely represent a change from effusive to explosive activity, rather than an increase in NAIP activity. Detrital δ7Li values and clay abundances suggest that volcanic ash production increased basaltic reactive surface area, likely enhancing silicate weathering and atmospheric carbon sequestration in the early Eocene. Signals in lipid biomarkers and Os isotopes, traditionally used to trace paleotemperature and weathering changes, are used here to track seaway connectivity. These proxies indicate that the North Sea was rapidly cut off from the North Atlantic in under 12 kyr during the PETM recovery due to NAIP thermal uplift. Our findings reinforce the hypothesis that the emplacement of the NAIP had a profound and complex impact on Paleocene–Eocene climate, both directly through volcanic and thermogenic degassing, and indirectly by driving regional uplift and changing seaway connectivity.

Abstract. Generating spatial crop yield information is of great significance for academic research and guiding agricultural policy. Most existing public yield datasets have a coarse spatial resolution. Although these datasets are useful for analyzing regional temporal and spatial change, they cannot deal with spatial heterogeneity, which happens to be the most significant characteristic of the Chinese small-scale farmers' economy. Hence, we generated a 30-m Chinese winter wheat yield dataset (ChinaWheatYield30m) for major winter wheat-producing provinces in China for the period 2016–2021 with a semi-mechanistic model (hierarchical linear model, HLM). The yield prediction model was built by considering the wheat growth status and climatic factors. It can estimate wheat yield with excellent accuracy and low cost using a combination of satellite observations and regional meteorological information (i.e., Landsat 8, Sentinel-2 and ERA5 data from the Google Earth Engine (GEE) platform). The results were validated by using in situ measurements and census statistics and indicated a stable performance of the HLM model based on calibration datasets across China, with r of 0.81** and nRMSE of 12.59 %. With regards to validation, the ChinaWheatYield30m dataset was highly consistent with in situ measurement data and census data, indicated by r (nRMSE) of 0.72** (15.34 %) and 0.73** (19.41 %). With its high spatial resolution and accuracy, the ChinaWheatYield30m is a valuable dataset that can support numerous applications, including crop production modeling and regional climate evaluation.

Abstract. Wild fires exerts strong influences on the environment, ecology, economy and public security. However, the existing hourly JMA-Himawari fire product presents large uncertainties and not suitable for reliable real-time fire monitoring in China. To fill this gap, we proposed an adaptive hourly NSMC-Himawari fire product for China based on the original Himawari source by employing a dynamical threshold for fire-extraction and a database of ground thermal sources. According to the visually-extracted reference and consistence check, we found NSMC-Himawari fire product effectively removed a majority of false fire alarms included in the JMA-Himawari fire product. Based on a rare field-collected ground reference dataset, we evaluated the reliability of JMA-Himawari and NSMC-Himawari fire product across China. The overall accuracy of JMA- Himawari fire product was 54 % and 59 % (not considering the omission errors) respectively. As a comparison, by identifying more real fire pixels and avoiding a majority of false fire alarms, the overall accuracy of NSMC-Himawari fire product was 80 % and 84 % (not considering the omission errors) respectively, making it an ideal source for improved real-time fire monitoring across China. This research also provides useful reference for employing local dataset of underlying surfaces and thermal sources to enhance the accuracy of global fire products in specific regions.

A strontium isoscape of northern Australia
Authors: de Caritat Patrice , Dosseto Anthony , Dux Florian
Published: January 2023

Abstract. Strontium isotopes (87Sr / 86Sr) are useful in the Earth sciences as well as in forensic, archaeological, palaeontological, and ecological sciences. As very few large-scale Sr isoscapes exist in Australia, we have identified an opportunity to determine 87Sr / 86Sr ratios on archive fluvial sediment samples from the low-density National Geochemical Survey of Australia (www.ga.gov.au/ngsa; last access: 15 December 2022). The present study targeted the northern parts of Western Australia, the Northern Territory and Queensland, north of 21.5° S. The samples were taken mostly from a depth of ~60–80 cm in floodplain deposits at or near the outlet of large catchments (drainage basins). A coarse (< 2 mm) grain-size fraction was air-dried, sieved, milled then digested (hydrofluoric acid + nitric acid followed by aqua regia) to release total Sr. The Sr was then separated by chromatography and the 87Sr / 86Sr ratio determined by multicollector-inductively coupled plasma mass spectrometry. Preliminary results demonstrate a wide range of Sr isotopic values (0.7048 to 1.0330) over the survey area, reflecting a large diversity of source rock lithologies, geological processes and bedrock ages. Spatial distribution of 87Sr / 86Sr shows coherent (multi-point anomalies and smooth gradients), large-scale (> 100 km) patterns that appear to be broadly consistent with surface geology, regolith/soil type, and/or nearby outcropping bedrock. For instance, the extensive black clay soils of the Barkly Tableland define a > 500 km-long northwest-southeast-trending unradiogenic anomaly (87Sr / 86Sr < 0.7182). Where carbonate or mafic igneous rocks dominate, a low to moderate Sr isotope signature is observed. In proximity to the outcropping Proterozoic metamorphic basement of the Tennant, McArthur, Murphy and Mount Isa geological regions, conversely, radiogenic 87Sr / 86Sr values (> 0.7655) are observed. A potential correlation between mineralisation and elevated 87Sr / 86Sr values in these regions needs to be investigated in greater detail. Our results to-date indicate that incorporating soil/regolith Sr isotopes in regional, exploratory geoscience investigations can help identify basement rock types under (shallow) cover, constrain surface processes (e.g. weathering, dispersion), and, potentially, recognise components of mineral systems. Furthermore, the resulting Sr isoscape and future models derived therefrom can also be utilised in forensic, archaeological, paleontological and ecological studies that aim to investigate, e.g., past and modern animal (including humans) dietary habits and migrations. The new spatial Sr isotope dataset for the northern Australia region is publicly available (de Caritat et al., 2022a; https://dx.doi.org/10.26186/147473; last access: 15 December 2022).

Published: January 2023

Abstract. Precipitation nowcasting has important implications for urban operation and flood prevention. Radar echo extrapolation is the common method in precipitation nowcasting. Using deep learning models to extrapolate radar echo data has great potential. The increase of lead time leads to a weaker correlation between real rainfall evolution and generated images. The evolution information is easily lost during extrapolation, which is reflected as echoes attenuation. Existing models, including Generative Adversarial Network (GAN)-based models, are all difficult to reduce loss and curb attenuation, which results in insufficient rainfall prediction accuracy. Aim to the problem, a Spatiotemporal Process Intensification Network (GAN-argcPredNet v2.0) based on GAN-argcPredNet v1.0 is designed. GAN-argcPredNet v2.0 reduces the loss by intensifying the influence of the previously input evolution information. A Spatiotemporal Information Changes Prediction (STIC-Prediction) network is designed as generator. With the intensification of echo feature sequence, the generator focuses on the spatiotemporal variation and generates more accurate images. Furthermore, discriminator is a Channel-Spatial Convolution (CS-Convolution) network. The discriminator intensifies the discrimination of echoes information by strengthening spatial information of single image. Identification results are fed back to the generator, which reduces the loss of important evolutionary information. The experiments are based on the radar dataset of South China. The results show that GAN-argcPredNet v2.0 performs better than other models. In heavy rainfall prediction, compared with baseline, the Probability of Detection (POD), the Critical Success Index (CSI), and the Heidke Skill Score (HSS) increase by 24.8 %, 22.2 % and 21.5 % respectively. The False Alarm Ratio (FAR) decreases by 3.76 %.

Abstract. Mountainous areas are the main water-producing and source areas of rivers. Global climate change is transforming the distribution of plants and forms of water use. Therefore, a clear understanding of evapotranspiration in mountainous forest zone is key for understanding the ecohydrological effect of vegetation and its influence on the water cycle of the watershed. We quantified the evapotranspiration processes in the forest belts of the Qilian Mountains as well as their contribution to runoff yield and concentration based on precipitation, soil water, and plant water samples and experimental data. The study showed that transpiration of Qinghai spruce accounted for the highest proportion of evapotranspiration in the entire Qinghai spruce forest ecosystem, with an average of 79 %, which means that transpiration is much greater than evaporation. Soil water content and air humidity were the dominant factors influencing evapotranspiration in Qinghai spruce forest belts. The growing season of Qinghai spruce is characterized by greater evapotranspiration than precipitation in each month. Consequently, the forest zone does not yield flows in the eastern part of the Qilian Mountains. The warming of global temperatures and human activities are likely to trigger shifts in the distribution areas and evapotranspiration regimes of Qinghai spruce, which in turn will lead to a change in water resource patterns in the basin.

Published: January 2023

Abstract. Attribution of sea-level change to its different drivers is typically done using a sea-level budget approach. While the global mean sea-level budget is considered closed, closing the budget on a finer spatial scale is more complicated due to, for instance, limitations in our observational system and the spatial processes contributing to regional sea-level change. Consequently, the regional budget has been mainly analysed on a basin-wide scale. Here we investigate the sea-level budget at sub-basin scales, using two machine learning techniques to extract domains of coherent sea-level variability: a neural network approach (self-organizing map, SOM) and a network detection approach (δ-MAPS). The extracted domains provide more spatial detail within the ocean basins and indicate how sea-level variability is connected among different regions. Using these domains we can close, within 1σ uncertainty, the sub-basin regional sea-level budget from 1993–2016 in 100 % and 76 % of the SOM and δ-MAPS regions, respectively. Steric variations dominate the temporal sea-level variability and determine a significant part of the total regional change. Sea-level change due to mass exchange between ocean and land has a relatively homogeneous contribution to all regions. In highly dynamic regions (e.g. the Gulf Stream region) the dynamic mass redistribution is significant. Regions where the budget cannot be closed highlight processes that are affecting sea level but are not well captured by the observations, such as the influence of western boundary currents. The use of the budget approach in combination with machine learning techniques leads to new insights into regional sea-level variability and its drivers.
Geothermal heat flux is the dominant source of uncertainty in englacial-temperature-based dating of ice rise formation
Authors: Montelli Aleksandr , Kingslake Jonathan
Published: January 2023

Abstract. Ice rises are areas of locally grounded, slow-moving ice adjacent
to floating ice shelves. Temperature profiles measured through ice rises
contain information regarding changes to their dynamic evolution and
external forcings, such as past surface temperatures, past accumulation
rates and geothermal heat flux. While previous work has used borehole
temperature–depth measurements to infer one or two such parameters, there
has been no systematic investigation of parameter sensitivity to the
interplay of multiple external forcings and dynamic changes. A
one-dimensional vertical heat flow forward model developed here examines how
changing forcings affect temperature profiles. Further, using both synthetic
data and previous measurements from the Crary Ice Rise in Antarctica, we use
our model in a Markov chain Monte Carlo inversion to demonstrate that this
method has potential as a useful dating technique that can be implemented at
ice rises across Antarctica. However, we also highlight the non-uniqueness
of previous ice rise formation dating based on temperature profiles, showing
that using nominal values for forcing parameters, without taking into
account their realistic uncertainties, can lead to underestimation of dating
uncertainty. In particular, geothermal heat flux represents the dominant
source of uncertainty in ice rise age estimation. For instance, in Crary Ice
Rise higher heat flux values (i.e. about 90 mW m−2) yield grounding
timing of 1400 ± 800 years, whereas lower heat flux of around 60 mW m−2 implies earlier ice rise formation and lower uncertainties in the
ice rise age estimations (500 ± 250 years). We discuss the utility of
this method in choosing future ice drilling sites and conclude that
integrating this technique with other indirect dating methods can provide
useful constraints on past forcings and changing boundary conditions from
in situ temperature–depth measurements.
Increased vertical resolution in the stratosphere reveals role of gravity waves after sudden stratospheric warmings
Authors: Wicker Wolfgang , Polichtchouk Inna , Domeisen Daniela I. V.
Published: January 2023

Abstract. Sudden stratospheric warmings (SSWs) have a long-lasting effect within the stratosphere as well as impacts on the underlying troposphere. However, sub-seasonal forecasts of the winter polar stratosphere fail to use their full potential for predictability as they tend to underestimate the magnitude and persistence of these events already within the stratosphere. The origin of this underestimation is unknown.
Here, we demonstrate that the associated polar stratospheric cold bias following SSW events in sub-seasonal hindcasts can be halved by increasing vertical model resolution, suggesting a potential sensitivity to gravity wave forcing.
While the predictability of the planetary Rossby wave flux into the stratosphere at lead times longer than a week is limited, the existence of a critical layer for gravity waves with a low zonal phase speed caused by the disturbed polar vortex provides predictability to the upper stratosphere. Gravity wave breaking near that critical layer can, therefore, decelerate the zonal flow consistently with anomalous subsidence over the polar cap leading to warmer temperatures in the middle polar stratosphere.
Since the spectrum of gravity waves involves vertical wavelengths of less than 4000 m, as estimated by wavelet analysis, a high vertical model resolution is needed to resolve the positive feedback between gravity wave forcing and the state of the polar vortex. Specifically, we find that at a spectral resolution of TCo639 (approximate horizontal grid spacing of 18 km) at least 198 levels are needed to correctly resolve the spectrum of gravity waves in the ECMWF Integrated Forecasting System. Increasing vertical resolution in operational forecasts will help to mitigate stratospheric temperature biases and improve sub-seasonal predictions of the stratospheric polar vortex.
COVID-19 PREVALENCE AMONG CANCER PATIENTS IN KAZAKHSTAN
Authors: Menbaev S.
Published: January 2023

Relevance: The new coronavirus infection, COVID-19, has been spreading rapidly around the world since 2019, affecting the healthcare
systems of most countries. According to recent studies, malignant diseases increase the susceptibility to COVID-19 and are a risk factor for worse
clinical outcomes in COVID-19 patients. COVID-19 also increases the risk of disease progression in patients with malignancies.
The study aimed to study the prevalence of COVID-19 among cancer patients in Kazakhstan.
Methods: The analysis included open-access articles published since 2019 and indexed in PubMed, Cochrane, Google Scholar, and e-Library by keywords “cancer,” “malignant neoplasms,” “COVID-19”, “cancer patients,” “mortality risk.” The official statistics data, medical
information systems of the Republic of Kazakhstan (Electronic Register of Cancer Patients, Electronic Register of Inpatient Patients), and official
periodicals on cancer incidence and mortality for 2020-2021 and COVID-19 incidence and mortality for 2020-2022 in Kazakhstan were studied.
Results: In the Republic of Kazakhstan, in 2020-2021, the highest cancer incidence was registered in the North Kazakhstan (1.79-1.87%),
Pavlodar (1.57-1.63%), Karaganda (1.54-1.53%) and Kostanay (1.53%) regions. The lowest rates were recorded in the Turkestan (0.42-0.41%),
Kyzylorda (0.57-0.59%), and Mangistau (0.62%) regions, and the city of Shymkent (0.60%). The highest cancer mortality in Kazakhstan was registered in the Turkestan (11.1%), Kyzylorda (10.2%), and Zhambyl (10.02%) regions in 2020, and in they Atyrau (25.4%), Turkestan (10.68%), and
West Kazakhstan (10.30%) regions in 2021.
The mortality from COVID-19 among patients registered for cancer in 2020 was the highest in the city of Astana (1.06%), the Kyzylorda
(0.46%) and Turkestan (0.33%) regions, and in 2021 – in the cities of Shymkent (1.05%) and Astana (1,00%), the Atyrau (0.93%) and West Kazakhstan (0.94%) regions.
Conclusion: Thus, COVID-19 prevalence among cancer patients and their increased mortality during the pandemic, including the cases where
the main cause of death was not an oncological process but the consequences of the viral infection, evidence the need to adjust the rules of statistical recording of cancer patients morbidity and mortality, the algorithms and protocols of diagnosis and treatment of cancer patients.
THE ROLE OF PIVKAII ONCOMARKER IN HEPATOCELLULAR CARCINOMA:
А LITERATURE REVIEW
Authors: Aubakirova A.Т. , Аbdilova G. , Nurgalyeva A. , Abdigakyeva G. , Serikuly Ye. , Baichalova A.
Published: January 2023

Relevance: Hepatocellular carcinoma (HCC) ranks sixth among the most common malignant neoplasms in the world and accounts for about
5.6% of all human malignant neoplasms. Despite encouraging progress in the diagnosis and treatment of HCC, the prognosis remains unsatisfactory, i.e., with a 5-year overall survival rate below 10.3%. However, the survival rate can reach 50-74% if early detection and therapeutic intervention are carried out on time. However, unfortunately, about 50% of HCC cases are diagnosed at a late stage.
The protein induced by the absence of vitamin K or antagonist-II (PIVKA-II), also known as Dez-γ-carboxyprothrombin (DCP), is another
marker specific to HCC. In several studies, elevated PIVKA-II serum levels were associated with HCC. Many authors have proven the PIVKA-II
applicability for HCC monitoring.
This study aimed to compare the efficiency of alpha-fetoprotein and des-gamma-carboxyprothrombin serological markers in HCC.
Methods: The study included the review of published articles on the causes of HCC and the analysis of literature to compare cancer markers
efficacy, including PIVKA-II and alpha-fetoprotein (AFP), in detecting HCC.
Results: The published results evidence an important role of PIVKA-II in HCC early detection, since PIVKA-II elevation in risk-group patients
predicts HCC development in two years. Higher PIVKA-II levels can indicate a bigger tumor or a higher clinical stage. Besides, HCC patients with
metastasis to the lymph nodes and distant metastasis had much higher PIVKA-II levels compared to non-metastatic patients. So, high PIVKA-II
levels can to a certain extent reflect poor prognosis in HCC patients.
Conclusion: The reviewed publications report much higher PIVKA-II serum levels in patients with HCC compared to patients with benign liver
diseases or healthy people. Besides, PIVKA-II has a higher diagnostic capacity than AFP due to its higher levels, sensitivity, and specificity. Thus,
we can expect high sensitivity and efficiency of the PIVKA-II oncomarker in HCC early diagnostics.

Epidermoid and dermoid cysts are slow-developing formations of ectodermal origin and their most common location is underneath the skin. Epidermoid cysts of the jaw bones are extremely rare, with only several cases documented in the dental literature. Their most common intraoral location is the floor of the oral cavity, the tongue, lips, palate and cheeks. They are slow-growing painless formations, usually discovered incidentally when imaging scans, as well as histopathological examinations, are performed. A patient sought assistance from us, presenting with painful swelling in the right side of the mandible, without added infection. The radiograph and the CBCT scans revealed a lesion in the region of tooth #48, extending halfway into the mandibular ramus, which was surgically removed under general anesthesia. The surgical technique was cystectomy- complete removal of the cyst with the fibrous capsule. The mucosa above the bone defect is then tightly sealed. The histopathology report described an epidermal cyst. It follows that this type of lesions, though extremely uncommon in the jaw bones, must be considered in the differential diagnosis with odontogenic cysts like follicular odontogeneic cyst and odontogeneic keratocyst.

Following substantial domestic and family violence (DFV) reforms in Australia in recent years, the identification of victim-survivors is increasingly embedded across service system responses. In contrast, while men using DFV often have diverse service system contact for co-occurring issues, their use of DFV is often not identified. This mixed-methods study examines current screening and risk assessment practices for DFV perpetration in service systems that frequently encounter men who may be using DFV, including mental health, alcohol and other drug services, corrections and child protection services. Results show significant variation in screening and risk assessment practices and attitudes across service areas.

The eggs were subjected to the treatments as follows: T1 control group, without spray or injection, T2 injected with 0.5 mL of distilled water, T3 injected with 0.5 ml 12% Albumin egg, T4 injected with 0.5 mL of 20% Dextrin, T5 injected with 0.5 ml mixture of 12% Albumin egg + 20% Dextrin, T6 spraying of vit C only, T7 injected with 0.5 ml of 12% Albumin egg + spray with vit C, T8 injected with 0.5 ml of 20% Dextrin + Taurine Ascorbic acid powder, T9 injected with 0.5 ml mixture of 12% Albumin egg + 20% Dextrin + Spray vit C. the results showed there were no significant differences on hatching rate of fertile eggs, late embryonic mortality, alive pipped, dead pipped, length of the chick, Tuna traits and percentage weight of liver. The body weight of chicks increased significantly in T9 compared to T3 and T4, without any differences among other treatments. However, the percentage of remains yolk was decreased in T4 as the lowest of percentage weight of remains yolk among treatments. The percentage weight of heart was significantly increased in T5 among other treatments. The T4 was higher than T1, T3 and T7 in term of gizzard percentage weight, T8 was superior in percentage weight of glandular stomach among all treatments. Significant difference was observed in percentage weight of fabricia gland and intestine for T5 compared to others. High significant differs in length of villa for intestinal tissue in T8 and T9 compared with other treatments. We conclude from this study that injection Dextrin + spraying with vitamin C has significantly improved the rate some relative weights of internal organs, the most important of which is the relative weight of bursa.

Published: January 2023

Percursos didáticos que se amparem em perspectivas construtivistas de aprendizagem são caminhos aspirados desde o final do século XX pelos estudiosos em educação. Outrossim, o processo avaliativo é um movimento complexo que demanda do professor certo esforço na busca por evidências da consolidação da aprendizagem. Posto isto, na perspectiva de uma aprendizagem significativa, este estudo apresenta uma proposta de Unidade de Ensino Potencialmente Significativa (UEPS) para a educação básica, além de uma sugestão para avaliar, por meio de parâmetros ausubelianos práticos, uma possível aprendizagem significativa que possa se desenvolver a partir da aplicação da Unidade. Para a avaliação do aprendizado com significado de forma mais assertiva, sugere-se a análise de critérios e itens que abarquem os domínios cognitivo, atitudinal, ciente, consciente e contextual da aprendizagem, utilizando múltiplos instrumentos avaliativos. Desta forma, as propostas aqui discutidas constituem-se como um recurso para subsidiar a análise e entendimento acerca dos episódios de aprendizagem significativa.
