Teacher Training and Inclusive Physical Education under analysis
Authors: Batista Paula , Resende Rui
Published: August 2024

The April 1974 50th anniversary is a reminder of the substantial changes in the field of education in which, from the principles of exclusion and discrimination, the concept of education democratization was broadened to represent an important space for social advancement. Alongside the massification of the education system, the ideas of inclusion emphasize the need for schools to recognize the added value of the diversity of their students, finding ways to deal with differences, adjusting teaching processes to the individual characteristics and conditions of each student, challenging teachers to configure inclusive and equitable educational practices. Teacher training should focus on student-centered teaching, fostering inclusive education and collaborative learning.
(Re)constructing the idea of being fit and be in shape in Physical Education classes
Authors: Maia Cristiana , Silva Ana Mafalda , Fonseca Manuela , Moreira Maria Madalena , Batista Paula
Published: August 2024

The perception of being fit and self-image are important for well-being. In the school curriculum physical education is the subject that treats the body as a pedagogical object, representing a privileged space to promote the construction of adjusted understanding to each student of what it means to be fit and to improve self-image in favour of building active lifestyle habits. This study reports on a pedagogical experience in physical education that aimed to contribute to the reconstruction of being in shape and being fit by using strategies that would help students adjust and improve their expectations in the perception of their self and being fit, in conjunction with improving physical fitness. The participants were 21 students that carried out activities related to body image, being fit, being in shape, a training program, and challenges. Data collection included a body image assessment form, a questionnaire, podcast, focus groups and physical fitness tests. The results showed that the students changed their initial idea of what it means to be fit, had a positive adherence to activities outside the school context and an apparent improvement in their physical fitness levels.

At present, deep neural network has been widely used in many research fields. However, with the in-depth research on artificial intelligence research, it is found that artificial intelligence technology based on deep neural networks bringsconvenience coming with potential security risks. For example, an attacker may misguide the image classification model to output a wrong result with high confidence by adding slight perturbations to a clean image via the adversarial example method. Compared with the previous methods of adding additional information to the images to generate adversarial examples, Ranjie Duan et al. proposed the AdvDrop algorithm. In this algorithm, adversarial examples are generated by deleting the existing information of the images, which is realized by adjusting the quantization step. However, in the quantization process, the AdvDrop algorithm does not consider the different effects of different gradient values of the quantization table on the adversarial effect. In this regard, AdvDrop+ is proposed, that is, in each iteration, the quantization tables are updated according to the gradient numerical values scaled with a factor. To find the proper scaling factor, we find the gradient value of the highest frequency in the gradient histogram and compute its logarithm and the final result is the scaling factor. The experiments show that AdvDrop+ has better attack performance than AdvDrop under the setting of target attack with nearly the same image distortion. At the same time, AdvDrop+ retains the characteristic of AdvDrop, which can drop information.

The study of metamorphic rocks and deformation and metamorphic features in Gangdise-Lhasa metamorphic zone is helpful for the establishment of regional tectonic framework and the discussion of the evolution history of the region, which will provide new basic data for the study of geological structure evolution in the Qinghai-Tibet Plateau. There are few studies on metamorphic rocks in the northern area of Lhasa, Tibet. This paper summarizes and studies them from the perspective of petrography, and briefly discusses the stages of deformation and metamorphism. The area is divided into two metamorphic belts, which are divided into Yebagou-Gandansi metamorphic belt and Shexing-Binjiaolin metamorphic belt from south to north. The types of metamorphic rocks are slate, kyanite and schist. The dynamic metamorphism is manifested as brittle deformation and ductile deformation. The dynamic metamorphic rock belt developed in the area is several kilometers long, which basically belongs to the low green schist facies belt. The metamorphism in the area occurs under the geological background of the northward subduction, subduction and collision of the Neotethys oceanic crust plate. And with the change of tectonic environment and heat flow, different metamorphisms are produced in different geological development stages.

Published: August 2024

Tensile machine is a very sophisticated test equipment, which can test the mechanical properties of some materials. In the drawing machine, the clamping device is to prevent the relative displacement and vibration phenomenon in the process of tensile test. The clamping device is the most important part of the structure of the test machine, and the main task of the clamping device is to control the degree of freedom of the specimen needs to be clamped, so as to further add loads to the various specimens to be held, and finally complete the mechanical property test of the material. But at present, the existing fixture mechanism is mainly hydraulic, pneumatic, mechanical fixture. At present, the existing mechanical fixture still has bending stress during the clamping process, which will affect the accuracy of the experiment. Therefore, a clamping mechanism with adjustable clamping force and flat pushing is designed. An electric control type fixture mechanism is very rare, so in this paper, an electrically controlled fixture is designed on this basis. The main contents are as follows: (1) On the basis of the existing fixture types, the working mode of the fixture is studied, and the working principle related to the fixture is mastered. (2) The main components of the fixture mechanism are analysed, the design scheme is determined, and the selection of the components of the drive part and the selection of the related components within the fixture mechanism is completed. ( 3) The force analysis of the main body of the fixture is carried out by using theoretical mechanics knowledge, and the relevant calculations are completed. The solid modeling of the whole mechanism is completed by using SolidWorks. The force analysis of key parts is carried out by using ANSYS software, and the correctness and safety of material selection and design are verified. The main parts of the fixture mechanism to complete the corresponding force analysis, and the theoretical calculation results are compared and verified, and finally realize the electric control of the fixture mechanism and complete the design of the fixture mechanism.

Authors: Manasi Hivare  , Prajwal Dongre  , Sunil Magan More
Published: August 2024

The accelerating adoption of electric vehicles (EVs) has elicited the requirement for modern and developed charging solutions that promise efficiency, as well reliability. In this paper, we propose an Internet of Things (IoT) enabled DC electric vehicle charger to meet these requirements. The solution offers IoT functionalities for full and remote monitoring, diagnostics roadside assistance as well as charging management adapting to the available power. Making use of top-level sensors and connectivity, the charger system optimizes energy usage by intelligent grid balancing as well as enables dynamic load balancing techniques for installation-wise benefits such that it is possible to implement predictive maintenance. Meanwhile, IoT integration ensures a seamless user experience through mobile apps so that users can check the charging status of their vehicle and set up sessions at different times of the day while receiving important notifications. DC EV chargers are faster at charging than normal Alternating Current (AC) ones. They transform electricity from the grid into a form that can be directly applied in the vehicle battery. This ability translates to highly reduce charging times, which explains why they are well-suited for along highways and in commercial applications or urban settings where fast turnaround is critical. These trends are identified by service providers to improve charger placement and availability for drivers

Published: August 2024

The study aims to predict breast cancer survival using Naïve Bayes techniques by comparing different machine learning models on a comprehensive dataset of patient records. The main classification groups were survival and non-survival. The objective was to assess the performance of the Naïve Bayes classifier in the field of data mining and to achieve significant results in survival classification, aligning with current academic research. The Naive Bayes classifier attained an average accuracy of 91.08%, indicating consistent performance, though with some variability across different folds. Conversely, Logistic Regression achieved a higher accuracy of 94.84%, demonstrating proficiency in recognizing instances of class 1, yet encountering challenges with class 0.The Decision Tree model, with an accuracy of 93.42%, exhibited similar performance patterns. With an accuracy of 95.68%, Random Forest surpassed the Decision Tree. Nonetheless, all models encountered challenges in accurately classifying instances of class 0. The Naive Bayes algorithm was juxtaposed with K-Nearest Neighbors (KNN) and Support Vector Machines (SVM). Future research aims to enhance prediction models with novel methods and tackle the challenge of accurately identifying instances of class 0.

El análisis del comportamiento de una economía nacional permite identificar el desempeño regional y de sus actividades en cualquier ámbito territorial, relacionando cambios estructurales, procesos de crecimiento, distribución espacial y operación de sectores económicos (productivos), lo que contribuye en la formulación de acciones sectoriales promotoras del desarrollo económico. Por ello, el objetivo es analizar regiones y cultivos con Especialización Agrícola (EA), mediante el uso de Coeficientes de Análisis Regional (CAR) y cartografía temática basados en estadísticas oficiales de entidades mexicanas entre 2010-2017, para su caracterización y tipificación. Los resultados revelan una adopción del modelo con heterogeneidad en el númeroytipo de cultivos especializados regionalmente, presentándose mayores niveles de Especialización Agrícola en la Región Norte y Centro Occidente de México con granos y berries, y de manera general en cultivos exportables. Los niveles presentan una relación directamente proporcional con el valor de la producción, pero inversa con la superficie; destaca la importancia del acceso al mercado y ubicación geográfica como factores explicativos. Se concluye que la EA es producto de diferencias en la formación de áreas de mercado, factores tecnológicos y productividades globales y sectoriales.

Authors: Santos Thiago Assis , Girotto Suyanne Paula Schwade , Radaelli Patricia Barth , Madureira Eduardo Miguel Prata
Published: August 2024

O processo de envelhecimento tem se tornado um tema discutido mundialmente devido aos seus impactos na economia e no cenário internacional. A senescência, que antes era um tema pouco discutido, tornou-se alvo de grande atenção na esfera pública, uma vez que o desenvolvimento da medicina e da ciência tem permitido o aumento da expectativa de vida associado a uma saúde que antes era inimaginável. Diante dessa realidade, o governo brasileiro criou o Estatuto do Idoso com a finalidade de garantir a manutenção dos direitos à população idosa, de forma que não só a saúde seja assegurada, mas também a inclusão social e a qualidade de vida. A busca pelo Ensino Superior, pelos idosos, tem se tornado uma alternativa para o desenvolvimento de novos objetivos, de habilidades e competências, de outras oportunidades, ou ainda a realização de projetos que antes não lhes fora possível. Analisar como essa questão – da inserção do idoso no Ensino Superior – tem se dado, em diferentes cenários no Brasil, com seus inúmeros desafios, constituiu-se como objetivo principal dessa pesquisa. Para isso, a investigação deu-se a partir do cruzamento de dados nas plataformas do DATASUS, IBGE, e INEP, buscando discriminar a verdadeira situação da saúde e o acesso da terceira idade à educação superior no contexto brasileiro.

Typhoon statistics in variable resolution Asia-Pacific CAM-SE
Authors: Zheng Duofan , Lee Shao-Yi , Lin Wenting , Ran Qi , Dong Wenjie
Published: August 2024

Abstract. Three Asia-centric configurations of the Community Atmosphere Model with the Spectral Element dynamical core (CAM-SE) were set up, with horizontal resolutions of approximately 1° globally, 1° increasing to 0.5° over the Asia-Pacific, and 1° increasing to 0.25°. A typhoon tracking algorithm was developed to extract the tracks of typhoons generated by the simulations. The typhoon intensities were bias corrected using scale conversion factors calculated from a comparison of tracks extracted from the European Centre for Medium-Range Weather Forecasts Reanalysis version 5 (ERA5) and the International Best Track Archive for Climate Stewardship (IBTrACS). Typhoon frequency, track density, genesis locations, and energy were calculated from 20 years of equilibrium climate simulations using the three configurations, then compared with the statistics from ERA5 and IBTrACS. The 1° and 0.5° CAM-SE simulations were unable to produce enough “Super Typhoons” (maximum sustained central wind speed ⩾ 51 m s-1) even after bias correction. The 0.25° simulation managed to produce enough “Super Typhoons”, indicating that at least 0.25° horizontal resolution is advisable for global climate simulations to produce appropriate “Super Typhoon” statistics. The regionally refined 0.25° CAM-SE configuration was estimated to be at least two times faster than a globally 0.25° typical configuration.
Incorporating science communication and bicultural knowledge in teaching a blended volcanology course
Authors: Kennedy Ben , Engel Kamen , Davidson Jonathan , Tapuke Sylvia , Hikuroa Dan , Martin Tim , Zaka Pinelopi
Published: August 2024

Abstract. A variety of skills can be taught alongside course content. In the University of Canterbury third-year university course on magmatic systems and volcanology, we chose to focus on teaching bicultural competence and science communication while transforming the course to a more skills-based, flexible, flipped classroom model. We document the development process and measure student perceptions associated with these skills. We used two edX massive open online volcanology courses (MOOCs) as flexible skills-focussed learning resources to replace lectures and supplement hands-on laboratory and tutorial sessions to teach volcanology. We compare the flexible skills-focussed courses with baseline data from 2021, an initial iteration of the course which included interactive volcanology lectures, and an online Iceland virtual fieldtrip component. The new skills-focussed course was developed using the original 2021 interactive online Iceland virtual fieldtrip to create the two virtual fieldtrip-based MOOCs with new bicultural and science communication components. To achieve this, we used cultural advisors from connections through NZ research programs and kaiārahi (Māori learning advisors) from the University of Canterbury. In the course, these experts ensured appropriate cultural guidance at specific volcanic sites and appropriate assessments. Mātauranga (Māori knowledge) of volcanoes is included and taught by video of kōrero (oral knowledge) from members of local mana whenua in the areas that are visited in the course. In this paper we describe the development of a flipped classroom MOOC featuring bicultural competence and science communication skills, and we report students’ reflections on learning with a focus on bicultural competence and science communication. We analyse student reflections and comments from the two iterations of the online content by specifically coding for comments regarding skills learnt. Student responses to the question What did you learn in this course and why is it important to you and/or your potential career? showed a marked shift. Compared to 2021, in 2022 students’ reflections were more likely to highlight a skill rather than content, and there was a large increase in students who reported science communication or bicultural competence as a potential skill that would be useful to them. Student quotes from throughout the course and in response to the reflective question Has this course influenced your bicultural competence? are used to explore how and why these skills were valued by the students. These courses provide a freely available and potentially flexible model to teach bicultural and science communication skills alongside volcanology.
A New Vision of the Adriatic Dense Water Future under Extreme Warming
Authors: Denamiel Clea Lumina , Tojčić Iva , Pranić Petra
Published: August 2024

Abstract. We use the Adriatic Sea and Coast (AdriSC) kilometer-scale atmosphere-ocean model to assess the impact of a far-future extreme warming scenario on the formation, spreading, and accumulation of both the North Adriatic dense Water (NAddW) over the entire basin, including the Jabuka Pit accumulation site, and the Adriatic Deep-Water (AdDW) over the Southern Adriatic Pit (SAP). Our key findings differ from previous studies that used coarser Mediterranean climate models and did not update the thresholds for dense and deep- water definitions to account for the far-future background density changes caused by warmer sea surface temperatures. We show that surface buoyancy losses at NAddW generation sites, driven by evaporation, are expected to increase by 15 % under extreme warming, despite a 25 % reduction in the intensity and spatial extent of Bora winds. As a result, future NAddW formation will remain similar to present conditions. However, the volume of dense water in the Jabuka Pit will decrease due to the increased far-future stratification. Additionally, dense water transport between the Jabuka Pit and the deepest part of the SAP will stop, as future NAddW will be lighter than the AdDW. Regarding Ionian-Adriatic exchanges, extreme warming will not affect the impact of the Bimodal Oscillation System on the Adriatic salinity variability, but future AdDW dynamics will be determined by density changes in the northern Ionian Sea. Our findings highlight the complexity of climate change impacts on Adriatic atmosphere-ocean processes and the importance of high-resolution models for more accurate far-future projections in the Adriatic Sea.
Random forests with spatial proxies for environmental modelling: opportunities and pitfalls
Authors: Milà Carles , Ludwig Marvin , Pebesma Edzer , Tonne Cathryn , Meyer Hanna
Published: August 2024

Abstract. Spatial proxies, such as coordinates and distance fields, are often added as predictors in random forest (RF) models without any modifications being made to the algorithm to account for residual autocorrelation and improve predictions. However, their suitability under different predictive conditions encountered in environmental applications has not yet been assessed. We investigate (1) the suitability of spatial proxies depending on the modelling objective (interpolation vs. extrapolation), the strength of the residual spatial autocorrelation, and the sampling pattern; (2) which validation methods can be used as a model selection tool to empirically assess the suitability of spatial proxies; and (3) the effect of using spatial proxies in real-world environmental applications. We designed a simulation study to assess the suitability of RF regression models using three different types of spatial proxies: coordinates, Euclidean distance fields (EDFs), and random forest spatial prediction (RFsp). We also tested the ability of probability sampling test points, random k-fold cross-validation (CV), and k-fold nearest neighbour distance matching (kNNDM) CV to reflect the true prediction performance and correctly rank models. As real-world case studies, we modelled annual average air temperature and fine particulate air pollution for continental Spain. In the simulation study, we found that RFs with spatial proxies were poorly suited for spatial extrapolation to new areas due to significant feature extrapolation. For spatial interpolation, proxies were beneficial when both strong residual autocorrelation and regularly or randomly distributed training samples were present. In all other cases, proxies were neutral or counterproductive. Random k-fold cross-validation generally favoured models with spatial proxies even when it was not appropriate, whereas probability test samples and kNNDM CV correctly ranked models. In the case studies, air temperature stations were well spread within the prediction area, and measurements exhibited strong spatial autocorrelation, leading to an effective use of spatial proxies. Air pollution stations were clustered and autocorrelation was weaker and thus spatial proxies were not beneficial. As the benefits of spatial proxies are not universal, we recommend using spatial exploratory and validation analyses to determine their suitability, as well as considering alternative inherently spatial modelling approaches.
Technical Note: An illustrative introduction to the domain dependence of spatial Principal Component patterns
Authors: Lehr Christian , Hohenbrink Tobias Ludwig
Published: August 2024

Abstract. Principal Component Analysis (PCA) of synchronous time series of one variable, e.g. water level or discharge, measured at multiple locations, has been applied in a wide spectrum of hydrological analyses. Principal Components (PCs) were used in regionalisation and to identify dominant modes, signals, processes or other hydrological properties of the analysed system. The possibility that the PCs of such analysis can exhibit domain dependence (DD) found only little recognition in the hydrological PCA literature so far. DD describes the situation in which the spatial PC patterns are mainly determined by the size and shape of the analysed spatial domain. Domain size means the spatial extent of the analysed data set, domain shape the spatial arrangement of the data sets´ locations. Thus, instead of the hydrological functioning of the analysed system, the spatial PC patterns rather reflect the functioning of the PCA within the context of the data set´s spatial domain. The effect is caused by homogeneous spatial autocorrelation in the analysed series, a common feature in hydrological data sets. DD patterns are distinct, with strong gradients and contrasts, and can come together with substantial accumulation of variance in the leading PCs. In addition, DD can cause effectively degenerate multiplets, i.e. PCs which are not well separable. All these features are highly suggestive and easily lead to wrong hydrological interpretations. Consequently, DD should be considered for any application in which the PCs are used to draw conclusions about spatially distinct properties of the analysed system. DD patterns calculated for the analysed spatial domain can be used as reference to test whether spatial PC patterns differ significantly from pure DD patterns. We present two methods, one stochastic, one analytic, to calculate DD reference patterns for defined spatial correlation properties and arbitrary spatial domains. With a series of synthetic examples, we explore the DD effect with respect to a) domain shape, b) domain size and spatial correlation length and c) effectively degenerate multiplets. Particular focus is given to the effect of DD on the explained variance of the PCs and the contrasts of their spatial patterns. Finally, considering DD is discussed. Accompanying this technical note, R-scripts to (i) demonstrate and explore the DD effect, and (ii) perform the presented DD reference methods are provided.
On capped Higgs positivity cone

The Wilson coefficients of the standard model effective field theory are subject to a series of positivity bounds. It has been shown that while the positivity part of the ultraviolet (UV) partial wave unitarity leads to the Wilson coefficients living in a convex cone, further including the nonpositivity part caps the cone from above. For Higgs scattering, a capped positivity cone was obtained using a simplified, linear unitarity condition without utilizing the full internal symmetries of Higgs scattering. Here, we further implement stronger nonlinear unitarity conditions from the UV, which generically gives rise to better bounds. We show that, for the Higgs case in particular, while the nonlinear unitarity conditions per se do not enhance the bounds, the fuller use of the internal symmetries do shrink the capped positivity cone significantly.

To quantify the bias caused by the calibration issue in the joint analysis of XMM-NuSTAR spectra and verify the effectiveness of the correction, in this work, we perform joint-fitting of the NuSTAR and EPIC-pn spectra for a large sample of 104 observation pairs of 44 X-ray bright active galactic nuclei (AGN). The spectra were extracted after requiring perfect simultaneity between the XMM-Newton and NuSTAR exposures (merging good time intervals (GTIs) from two missions) to avoid bias due to the rapid spectral variability of the AGN. Before the correction, the EPIC-pn spectra are systematically harder than the corresponding NuSTAR spectra by \begin{document}$\Delta \varGamma \sim 0.1 $\end{document}, subsequently yielding significantly underestimated cutoff energy Ecut and the strength of reflection component R when performing joint-fitting. We confirm that the correction is highly effective and can commendably erase the discrepancy in best-fit Γ, Ecut, and R. We thus urge the community to apply the correction when joint-fitting XMM-NuSTAR spectra, but note that the correction is limited to 3–12 keV and therefore not applicable when the soft X-ray band data are included. Besides, we show that as merging GTIs from two missions would cause severe loss of NuSTAR net exposure time, in many cases, joint-fitting yields no advantage compared with utilizing NuSTAR data alone. Finally, We present a technical note on filtering periods of high background flares for XMM-Newton EPIC-pn exposures in the small window (SW) mode.

Despite advances and improvements in infection prevention techniques, periprosthetic joint infection is a serious complication after total joint replacement. Prevention of purulent-septic complications is the most important strategy to combat this disabling complication, and should begin with identifying patient-related risk factors The aim: identification of risk factors associated with the development of purulent-septic complications after total arthroplasty of large joints. Methods. A retrospective review of the medical records of 71 patients who underwent orthopedic surgery from September 2022 to August 2023 was performed. Taking into account the development of purulent-septic complications, the patients were divided into 2 groups. Group I included patients with infectious complications after surgery, such as periprosthetic infection (n=9), suppuration of the surgical wound (n=8), respiratory infection (n=2), urinary tract infection (n=8), skin infections (n=8), in group II there were patients without complications. Results. A retrospective analysis showed that in the selected group of patients, 3.1% had purulent-septic complications. The average age of patients in group I was 61.4±11.5 years, in group II - 61.6±13.2 years (p>0.05). 47.3% of patients in group I had preoperative anemia, while in group II – only 5% (χ2 < 0.02). At the same time, the hemoglobin level before surgery in the first group was 117.3±3.4 g/l, and in the second – 136.3±8.6 g/l, p<0.001. It was also revealed that concomitant diabetes mellitus was observed in 52.6% of patients with purulent-septic complications, which was 5 times higher than in patients of group II (10.5%, χ2<0.04). Conclusion. Thus, a retrospective analysis showed that risk factors for the development of purulent-septic complications after total joint replacement were preoperative anemia, concomitant diabetes mellitus, and hyperglycemia above 7.5 mmol/l at the end of the operation.

По результатам анализа уровня потребности российской экономики в конкретных видах стратегических твердых полезных ископаемых, обеспеченности этих потребностей добычей и разведанными запасами выделено 4 сырьевых сценария. Рекомендуется их учитывать при планировании федеральных геологоразведочных работ и лицензировании участков недр для работ за счет средств недропользователей.

Based on the results of the analysis of the level of the Russian economy’s demand for specific types of strategic solid minerals, the supply of these needs with mining and the endowment of mining with proven reserves, 4 commodity scenarios have been identified. It is recommended to take them into account when planning federal geological exploration works and licensing of subsoil areas for works at the expense of subsoil users.

В ходе съемки листа Q-42 выполнено изотопное опробование подземных и поверхностных вод для оценки условий формирования ресурсов и запасов подземных вод зоны активного водообмена. Подземные воды верхнего этажа имеют инфильтрационное происхождение, запасы и ресурсы водоносных горизонтов формируются напрямую или с промежуточным резервуаром в виде подземных льдов. В настоящее время таяние пластовых льдов значительного вклада в баланс подземных вод не вносит. Во многих случаях воды инфильтрационного происхождения, поступившие в подземную гидросферу на водоразделах, подвергаются воздействию испарения, что отчетливо видно в изменении изотопного состава воды за счет неравновесного фракционирования. Суммарные потери воды на испарение можно оценить величиной до 20–25 %. Потери воды на испарение для водозаборов инфильтрационного типа малы и могут не приниматься во внимание. В северной части листа Q-42 основные запасы и ресурсы подземных вод содержатся в подрусловых и подозерных таликах. Генетическая связь подземных вод, эксплуатируемых водозаборами, с таликом для долины р. Обь устанавливается по изотопным и химическим данным достоверно. Для южной части листа, где мерзлота теряет сплошность, основные запасы и ресурсы подземных вод следует отнести к межм ерзлотным водоносным горизонтам.

Mapping survey of sheet Q-42 included isotope sampling to assess the formation conditions of the resources and reserves of groundwater in the zone of active water exchange. Groundwater of the upper zone has the modern recharge origin; its reserves and resources are formed directly from meteoric water or with an intermediate reservoir in the form of underground ice. Currently, melting of the formation ice does not make a significant contribution to the groundwater balance. In many cases, the recharge water that penetrates into aquifers at watersheds are partially evaporated, which is clearly visible in the change in the isotopic composition of water due to disequilibrium fractionation. The total loss of water due to evaporation can be estimated at up to 20–25%. Water losses due to evaporation for infiltration-type water intakes are small and may not be taken into account. In the northern part of the sheet Q-42, the main reserves and resources of groundwater are contained in sub-channel and sub-lake taliks. Connection of groundwater, which exploited by water intakes, with talik for the Ob River valley is reliably established based on isotope and chemical data. For the southern part of the sheet, where the permafrost loses continuity, the main reserves and resources of groundwater should be attributed to inter-permafrost aquifers.
