Published: February 2024

Abstract. Direct measurement of carbon and water fluxes at high frequency makes eddy covariance (EC) as the most preferred technique to characterize water use efficiency (WUE). However, reliability of EC fluxes is hinged on energy balance ratio (EBR) and inclusion of low-frequency fluxes. This study is aimed at investigating the role of averaging period to represent EC fluxes and its propagation into WUE dynamics. Carbon and water fluxes were monitored in a drip-irrigated Maize field at 10 Hz frequency and are averaged over 1, 5, 10, 15, 30, 45, 60, and 120 minutes considering daytime unstable conditions. Optimal averaging period to simulate WUE fluxes for each growth stage is obtained by considering cumulative frequency (ogive) curves. A clear departure of EBR from unity was observed during dough stage of the crop due to ignorance of canopy heat storage. Error in representing water (carbon) fluxes relative to the conventional 30 min. average is within ± 3 % (± 10 %) for 10–120 min. averaging and is beyond ± 3 % (± 10 %) for other time-averages. Ogive plots conclude that optimal averaging period to represent carbon and water fluxes is 15–30 min. for 6th leaf and silking stages, and is 45–60 min. for dough and maturity stages. Dynamics of WUE considering optimal averaging periods are in the range of 1.49 ± 0.95, 1.37 ± 0.74, 1.39 ± 0.79, and 3.06 ± 0.69 μmol mmol-1 for the 6th leaf, silking, dough, and maturity stages respectively. Error in representing WUE with conventional 30 min. averaging is marginal (< 1.5 %) except during the dough stage (12.12 %). Our findings can help in developing efficient water management strategies by accurately characterizing WUE fluxes from the EC measurements.

Abstract. Runoff originating from ground ice contained in landforms like rock glaciers and talus slopes represents an important water supply for the lowlands. Pseudo-relict rock glaciers host patchy permafrost, but appear to be visually relict, and therefore can be misinterpreted by using standard classification approaches. Permafrost content, spatial distribution and frequency of this type of rock glaciers are poorly known. Therefore, identifying pseudo-relict rock glaciers that might still host permafrost, and potentially ice, is crucial for understanding their hydrological role in a climate change context. This work analyses rock-glacier spring-water temperature in a 795 km2 catchment in the Eastern Italian Alps to understand how many rock glaciers classified as relict could have spring-water temperature comparable to intact rock glaciers, as possible evidence of their pseudo-relict nature. Spring-water temperature, often used as auxiliary to other approaches for specific sites, was used for a preliminary estimate of the permafrost presence in 50 rock glaciers classified as relict. In addition, we present electrical resistivity tomography (ERT) results on two relict rock glaciers with opposing spring-water temperature and surface characteristics to constrain spring-water temperature results at local scale. The results show that about 50 % of rock glaciers classified as relict might be pseudo-relict, thus potentially containing permafrost. Both supposedly relict rock glaciers investigated by geophysics contain frozen sediments. The majority of cold springs are mainly associated with rock glaciers with blocky and sparsely vegetated surface, but geophysics suggest that permafrost may also exist in rock glaciers below 2000 m a.s.l., entirely covered by vegetation and with spring-water temperature up to 3.7 °C. We estimate that pseudo-relict rock glaciers might contain a significant portion (20 %) of all the ice stored in the rock glaciers in the study area. These results highlight the relevance of pseudo-relict rock glaciers in periglacial environments. Even if not a conclusive method, spring-water-temperature analyses can be used to preliminarily distinguish between relict and pseudo-relict rock glaciers in wide regions.
Short-term cooling, drying and deceleration of an ice-rich rock glacier
Authors: Bast Alexander , Kenner Robert , Phillips Marcia
Published: February 2024

Abstract. Observations in the European Alps show a long-term rise in rock glacier velocities, which is often associated with increased air and ground temperatures and, more recently, water content. Long term rock glacier acceleration is superimposed by a high interannual variability of their velocity and there is still a gap in the quantitative assessment of the role of water in rock glaciers and the factors leading to short-term rock glacier deceleration. To address this research gap, we drilled three vertical boreholes in the Schafberg rock glacier, Swiss Alps, in August 2020. We documented their stratigraphy and equipped one of the boreholes with temperature sensors and piezometers, and the other two with cross-borehole electrical resistivity tomography sensors. Rock glacier velocities were determined using terrestrial laser scans. Using data from nearby weather stations and ground surface temperature sensors we analyzed the interactions between meteorological and subsurface conditions during a rock glacier deceleration period, from January 2021 to July 2023. Our findings show that a lowering of the water content in rock glaciers is crucial for intermittent, interannual rock glacier deceleration. The impact of the snowpack, both as an insulator and as a water source is significant for rock glacier kinematics. Winters with little snow and relatively dry summers appear to be ideal for rock glacier cooling and drying, leading to deceleration. Summer heat waves have limited impact on rock glacier velocity if they are preceded by snow-poor winters. Our study uses an innovative combination of borehole data to gain insights into rock glacier temperatures and water contents, allowing to detect relative changes in ice/water contents in ice-rich permafrost. The monitoring techniques used have the potential to contribute to a better understanding of factors affecting rock glacier kinematics and water availability.

Abstract. Borehole data are essential for conducting precise urban geological surveys and large-scale geological investigations. Traditionally, explicit modelling and implicit modelling have been the primary methods for visualizing borehole data and constructing 3D geological models. However, explicit modelling requires substantial manual labour, while implicit modelling faces problems related to uncertainty analysis. Recently, machine learning approaches have emerged as effective solutions for addressing these issues in 3D geological modelling. Nevertheless, the use of machine learning methods for constructing 3D geological models is often limited by insufficient training data. In this paper, we propose the semi-supervised deep learning using pseudo-labels (SDLP) algorithm to overcome the issue of insufficient training data. Specifically, we construct the pseudo-labels in the training dataset using the triangular irregular network (TIN) method. A 3D geological model is constructed using borehole data obtained from a real building engineering project in Shenyang, Liaoning Province, NE China. Then, we compare the results of the 3D geological model constructed based on SDLP with those constructed by a support vector machine (SVM) method and an implicit Hermite radial basis function (HRBF) modelling method. Compared to the 3D geological models constructed using the HRBF algorithm and the SVM algorithm, the 3D geological model constructed based on the SDLP algorithm better conforms to the sedimentation patterns of the region. The findings demonstrate that our proposed method effectively resolves the issues of insufficient training data when using machine learning methods and the inability to perform uncertainty analysis when using the implicit method. In conclusion, the semi-supervised deep learning method with pseudo-labelling proposed in this paper provides a solution for 3D geological modelling in engineering project areas with borehole data.
Identification of electro-mechanical interactions in wind turbines
Authors: Lüdecke Fiona Dominique , Schmid Martin , Cheng Po Wen
Published: February 2024

Abstract. Large direct drive wind turbines with a multi-megawatt power rating face design challenges due to scaling laws for high-torque generators. This work proposes to extend the design space by moving towards a more system-oriented approach. This requires an extension of the state-of-the-art wind turbine models with additional degrees of freedom to include electro-mechanical interactions. To limit the computational effort of such models, a profound understanding of possible interaction mechanisms is required. This work aims to identify interactions of an additional degree of freedom in the radial direction of the generator with the wind turbine structure, the aerodynamics and the wind turbine controller. Therefore, a Simpack model of the IEA 15MW RWT is implemented and coupled to a quasi-static analytical generator model for electromagnetic forces. The analytical model, sourced from literature, is code-to-code validated against a finite element model of the generator in Comsol Multiphysics. Electro-mechanical simulation results do not show interactions with the aerodynamics or the controller. However, interactions with the wind turbine structure occur. It is shown that the modelling approach can affect the system's natural frequencies, which can potentially impact the overall system design choices.

Authors: Cruz Ripoll Salceda Juan , Zevallos Polo Diana Sofía
Published: February 2024

Existe una relación notable entre fluidez y comprensión lectora. Para el desarrollo de la fluidez se han utilizado recursos como la lectura extensiva y la lectura asistida, especialmente las intervenciones de lecturas repetidas. No hay disponible ninguna revisión sistemática o metaanálisis acerca de la intervención en velocidad o fluidez lectora de alumnado hispanohablante. Para solventar esta situación, una búsqueda sistemática localizó 16 efectos independientes obtenidos con diferentes intervenciones sobre la velocidad lectora o sobre la fluidez lectora, entendida como combinación de velocidad y precisión o de velocidad y prosodia. En estos estudios participó alumnado desde 3º de Educación Infantil hasta 6º de Educación Primaria. Su efecto combinado fue de 0.47 al concluir las intervenciones.
Los resultados fueron notablemente heterogéneos. Se encontraron efectos positivos pequeños o moderados en intervenciones con componentes como mejora de la velocidad de denominación, lenguaje oral, decodificación, velocidad lectora, vocabulario o estrategias de comprensión. Los resultados fueron significativamente mayores en las intervenciones que incluían entrenamiento de la conciencia fonológica y en las que no trabajaban la comprensión. Los intervalos de predicción fueron positivos únicamente en las intervenciones que no incluían el entrenamiento de la conciencia fonológica, en las que trabajaban explícitamente la mejora de la velocidad y en las que trabajaban la comprensión: vocabulario o estrategias.

Published: February 2024

Stuttering is a speech disorder characterized by frequent and significant problems with normal fluency and flow of speech. People who stutter perceive themselves as poor communicators and develop negative speech attitudes. This development of a negative communicative attitude could be related to the expectations and high demands made by their parents about fluency. When these expectations exceed the stuttering individual’s abilities to produce fluent verbal communication, a stuttering episode occurs. This is perceived by the individual as a communicative performance not adequately meeting the requests. Consequently, these individuals often resort to various avoidance and escape behaviors and generally avoid discussing their experiences and feelings related to stuttering. Therefore, stimulating communication is essential during speech therapy sessions to expose experiences otherwise kept hidden both from children/adolescents and their parents. However, encouraging communication is far from simple. In an attempt to facilitate communication and foster a more effective relationship between persons who stutter and their parents, we implemented the so-called awareness drawing according to the IARA model at the opening of the stuttering assessment session. Fourteen children (M=10; F=4; mean age=10.42; SD=1.65) and eight adolescents (M=6; F=2; mean age = 15.25; SD=1.03) diagnosed with stuttering were involved in this study, along with their relatives (28 parents; M=10; F=18; mean age=31.14; SD=4.66 years). The results of the study revealed that the drawings and comments of children and adolescents with stuttering, along with their parents, can offer valuable insights into their experiences and perceptions of stuttering. Children and adolescents expressed a desire for acceptance and a wish to be recognized beyond their stuttering. They depicted solutions that encompass the involvement of both parents and speech therapists. The utilization of awareness drawing can have a substantial impact on speech therapists. During the stuttering assessment session, it can provide valuable insights into the emotions, thoughts of person who stutter, as well as the experiences of their parents. This, in turn, can enhance the design of therapeutic intervention.

Unraveling molecular similarities between colorectal polyps and colorectal cancer: a systems biology approach
Authors: Radak Mehran , Fallahi Hossein
Published: February 2024

Background/Aims: Colorectal cancer (CRC) and colorectal polyps are intimately linked, with polyps acting as precursors to CRC. Understanding the molecular mechanisms governing their development is crucial for advancing diagnosis and treatment. Employing a systems biology approach, we investigated the molecular similarities between polyp and CRC. Methods: We analyzed gene expression profiles, protein-protein interactions, transcription factors, and gene ontology to identify common differentially expressed genes (DEGs) and unravel shared molecular pathways. Results: Our analysis revealed 520 commonly dysregulated genes in polyps and CRC, serving as potential biomarkers and pivotal contributors to disease progression. Gene ontology analysis elucidated distinct biological processes associated with upregulated and downregulated DEGs in both conditions, highlighting common pathways, including signal transduction, cell adhesion, and positive regulation of cell proliferation. Moreover, protein-protein interaction networks shed light on subnetworks involved in rRNA processing, positive regulation of cell proliferation, mRNA splicing, and cell division. Transcription factor analysis identified major regulators and differentially expressed transcription factors in polyp and CRC. Notably, we identified common differentially expressed transcription factors, including ZNF217, NR3C1, KLF5, GATA6, and STAT3, with STAT3 and NR3C1 exhibiting increased expression. Conclusions: This comprehensive analysis enriches our understanding of the molecular mechanisms underlying polyp formation and CRC development, providing potential targets for further investigation and therapeutic intervention. Our findings contribute substantively to crafting personalized strategies for refining the diagnosis and treatment of polyps and CRC.
„Mieć Matkę, która nie umiera”. Retoryczna komunikacja świętości i pobożności maryjnej w kazaniach bł. Kardynała Stefana Wyszyńskiego
Authors: Ostafiński Witold
Published: February 2024

Maryja, Matka Boże, była ważnym, duchowym źródłem inspiracji i oparcia dla Kardynała Stefana Wyszyńskiego w jego życiu osobistym i biskupiej posłudze. Często odpływał się do jej wstawiennictwa, uważając ją za swoją opiekunkę i orędowniczkę w sprawach osobistych, kościelnych i narodowych. Ukazywał Maryję jako wzór do naśladowania, apostolskiego zaangażowania i nauczycielkę życia chrześcijańskiego. W przekazie kaznodziejskim używał prostego, przejrzystego języka, co pozwalało trafić do szerokiego grona odbiorców. Jego retoryka była pełna emocji i niezwykłego zaangażowania, które dodatkowo wzmacniało siłę przesłania. Często wykorzystywał metaforę, analogie, porównania, repetycję, stawiał retoryczne pytania. Zastosowanie różnego rodzaju figur retorycznych pomagało wzmocnić kaznodziejskie przesłanie, wywołać głębokie religijne emocje, uatrakcyjnić treść przekazu i przemówić do serc słuchaczy.
Konfrontacja marksizmu z chrześcijaństwem w społecznym nauczaniu bł. Stefana Wyszyńskiego. Historia i teraźniejszość
Authors: Bortkiewicz Paweł
Published: February 2024

Artykuł wydobywa z bogatej spuścizny bł. prymasa Stefana Wyszyńskiego dwa tematy, precyzyjnie określone na początku jego pracy naukowej, jak i na początku jego posługi biskupiej. W całości dotyczą one konfrontacji ideologii marksistowskiej z chrześcijaństwem. Nauczanie bł. Stefana Wyszyńskiego pozwala precyzyjnie określić cechy marksizmu wydobyte w sposób profetyczny i dlatego mające zastosowanie do współczesnego neomarksizmu. Ten wątek był podejmowany w twórczości naukowej ks. Stefana Wyszyńskiego w okresie jego pracy naukowej i redakcyjnej we Włocławku w latach 30. XX wieku. Na początku swojej posługi biskupiej w Lublinie bł. biskup Stefan Wyszyński przedstawił w sposób syntetyczny i oryginalny siłę chrześcijaństwa.

Lektura tych tekstów wydaje się być szczególnie pouczająca w dobie współczesnej, w której z jednej strony dokonuje się neomarksistowski „marsz przez kulturę i instytucje” (niekiedy można odnieść wrażenie, że także kościelne), a z drugiej strony, nie przemijającą pozostaje siła i oryginalność wiary chrześcijańskiej.
Synody w dziewięćsetletniej historii diecezji włocławskiej
Authors: Borucki Janusz
Published: February 2024

Zwołanie przez papieża Franciszka kolejnego, XVI już Zwyczajnego Zgromadzenia Ogólnego Synodu Biskupów, tym razem poświęconego zagadnieniu synodalności stało się okazją do refleksji nad synodalnością w Kościele w jej różnych wymiarach. W synodalność wpisuje się niewątpliwie instytucja synodów różnego typu (ekumeniczny, plenarny, prowincjalny, diecezjalny). Synody diecezjalne od wieków były miejscem, gdzie z jednej strony, poprzez stanowione uchwały, dokonywano kodyfikacji prawa diecezjalnego przystosowując je do przepisów prawa powszechnego, z drugiej zaś zgromadzenia synodalne stanowiły formę spotkań i współpracy biskupa z prezbiterami. W liczącej dziewięć stuleci historii diecezji włocławskiej udokumentowano odbycie 53 synodów diecezjalnych lub cząstkowych wpisujących się w synodalność kościoła. Przez wieki ustawodawstwo synodalne kształtowało formy duszpasterstwa i życie religijne wiernych w diecezji włocławskiej.

The content of tetracycline residues in poultry meat products can cause antibiotic resistance in humans who consume these products, so it is necessary to develop sensitive analytical techniques to determine the levels of tetracycline residues to assess the safety of these products for consumption. The molecular imprinting technique is a method to produce sorbents with molecular recognition capability of target compounds that can be used to increase the selectivity of solid phase extraction to extract tetracycline residues for further analysis. This study aimed to obtain a sorbent synthesized by molecular imprinting technique to analyze tetracycline in poultry meat products. The stages of the research began with the study of the interaction of functional monomers with template molecules, determining the association constants of functional monomers with template molecules, synthesis of imprinted polymer molecules using bulk and precipitation methods, evaluating the ability and adsorption capacity of the synthesized polymers, assess the selectivity of polymers for analog structures and physical characteristics with FTIR. The research showed that methacrylic acid was the best functional monomer with a binding energy value of -27.3776 kcal/mol. The higher adsorption capacity was achieved by Molecularly Imprinted Polymer (MIP) that was synthesized by precipitation method (MIP2) than the other MIP synthesized by bulk polymerization (MIP1) with a value of 0.8748 mg/g and 0.4077 mg/g, respectively. The analogous compounds' imprinting factor values for each MIP were 1.197 and 1.1272. The polymer synthesized by molecular imprinting technique is selective for extracting and analyzing tetracycline from poultry meat matrix.

The quest for better and more effective treatments has encouraged the search for therapies derived from natural sources to obtain effective immune therapy, considering that several pandemics have arisen caused by viruses. Developing fucoidan from brown algae in drug encapsulation as an immunomodulator could be more promising. This study aimed to produce nanoencapsulation loaded with fucoidan-purified extract from brown algae and to evaluate the influence of nanoencapsulation formulation on the immunomodulatory activity of fucoidan. Fucoidan was obtained from brown algae and extracted by hot aqueous, followed by ethanol purification. Nanoencapsulation of fucoidan purified extract was prepared using the ionic gelation method. The carbon clearance method was carried out for the immunomodulatory activity test of the nanoencapsulation of fucoidan purified extract. Nanoencapsulation of fucoidan purified extract with the optimum composition of maltodextrin 9.9% and S-TPP 0.1% (1:5) resulted in particle size of 715.4 nm, zeta potential -0.1 mV, pH 7.54, transmittance 97.54%+0.08, and entrapment efficiency 89.94%+0.17. The carbon clearance test showed that the nanoencapsulation of fucoidan was a strong immunostimulant with a phagocytosis index of 1.65. The development of nanoencapsulation could increase the phagocytosis index of fucoidan purified extracts from brown algae. Further molecular studies are needed to demonstrate the molecular activity of this preparation as an immunomodulator.

The study also delved into the potential effect of gender on students' achievement in chemistry. The pre-test, post-test non-equivalent control group design was utilized in this quasi-experimental study. There were 2,328 senior secondary two Chemistry students in the population. A sample size of 101 Chemistry students (43 males and 58 females) was selected using the purposive sampling technique from two intact classes at two co-educational schools. Using Kendall's Coefficient of Concordance (w), the Chemistry Achievement Test (CAT) reliability index was calculated to be 0.94. While ANCOVA was used to test the hypotheses at 0.05 level of significance, mean and standard were used to answer the research questions. The findings of the study showed that CIS enhances students’ achievement in chemistry more effectively than the conventional strategy. Also, gender has no significant influence on students’ achievement in chemistry. It was recommended among others that educational stakeholders should hold conferences and seminars to train the teachers on how to use CIS in teaching and learning chemistry. Moreover, CIS should be used to ensure and enhance gender equity in both chemistry learning and other school subjects.

Mental health challenge remains a stigmatized and under-addressed issue in Nigeria, contributing to significant societal challenge. Mass media campaigns have emerged as potential tools to raise awareness and combat the stigma. However, little research explores the effectiveness of these campaigns from the perspective of students. It is in the light of the above that this study examines students’ perception of the effectiveness of mass media campaigns on mental health awareness in Nigeria. The researchers embarked on this study with the intent of achieving four objectives and, based on the objectives of this study, four research questions were formulated to serve as a guide for this study. This study is hinged on the rational model theory. The researchers adopted the survey research design, and data were collected through the use of questionnaires. Findings from this study reveal that the majority of the respondents (31%) rated their level of awareness of mental health issues as very high as a result of their exposure to mass media campaigns on the subject. The study also reveals that the majority of the respondents (30%) noted that one of the impacts of mass media campaigns on the attitudes of students towards seeking help for mental concerns is that these campaigns have increased help-seeking behaviour among students. This study therefore concludes that mass media campaigns have proven to be effective in addressing mental health issues in Nigeria by raising awareness, promoting understanding, and reducing stigma. They have successfully disseminated information, encouraged help-seeking behavior, and fostered conversations about mental health. This study, among other things, recommends that producers of media messages should recognize the cultural and regional diversity within Nigeria and tailor mass media campaigns accordingly. Mental health issues may be perceived and addressed differently across various communities; therefore, the producers of media messages should produce campaigns that resonate with different cultural backgrounds, languages, and social norms to ensure inclusivity and effectiveness.

Kematian Yang Mematikan: Keberhasilan Misi Simson dalam Hakim-hakim 16
Authors: Prabowo Paulus Dimas
Published: February 2024

Simson adalah salah satu hakim-hakim yang memerintah Israel di zaman pramonarkhi. Dia dipanggil untuk mengemban misi yakni memulai penyelamatan Israel dari bangsa Filistin. Keunikan pribadinya terletak pada kekuatan super, status kenaziran, dan pola hidup yang dikendalikan kedagingan. Tidak sedikit penulis yang mengamatinya dan menyimpulkan bahwa misinya gagal. Namun, sungguhkah Simson telah gagal karena pola hidupnya yang tidak ideal? Artikel ini membuktikan bahwa misi Simson tidaklah gagal meskipun motivasi maupun metodenya tidak ideal, karena ada intervensi Tuhan di dalamnya. Melalui metode eksegesis sastra narasi yang melibatkan analisis struktur, analisis gaya, analisis redaksi, analisis eksegesis, dan analisis teologis diperoleh fakta bahwa misi Simson berhasil. Kekalahan Filistin dalam 16:23-31 telah diumumkan secara tersirat dalam 16:1-3. Jumlah musuh yang dibunuh meningkat. Data ini menunjukkan bahwa misi Simson berhasil.
