Effects of Different Welding Techniques on the Mechanical Properties of Weld Zones in LC-TMCP Steel
Authors:   Korean Industrial Technology Convergence Society, Eom Jung-Ho , Jeong Sang-Hoon , Kwon Soon-Doo
Published: April 2024

This study investigated the mechanical properties of thermal mechanical control process steel and obtained the following results. In a welded metal (WM) subjected to both single submerged arc welding (SSAW) and tandem SAW (TSAW), grain boundary ferrite (GBF) was generated along with a prior austenite grain boundary and ferrite side plate (FSP). In particular, TSAW with low basicity and a high heat input yielded coarser results than those of SSAW. In the heat affected zone (HAZ), as the heat input increased, the fraction of low-temperature transformation products such as bainite and acicular ferrite decreased, whereas the fraction of primary ferrites such as GBF, FSP, and polygonal ferrite (PF) tended to increase, and the grain size tended to coarsen. The hardness value of the WM increased in the order of electro gas welding, SSAW, and TSAW regardless of the heat input, and the hardness value of the HAZ tended to increase the softening width and decrease the minimum value with an increase in the heat input. Finally, the joint strength of the weld zone tended to decrease as the heat input increased. However, the joint strength of the weld zone under all the applied welding techniques met the value required by the base metal.
Comparison of Rod Consumption, Welding Time, and Welding Economy of Welding Rods of Various Diameters for Shielded Metal Arc Welding
Authors:   Korean Industrial Technology Convergence Society, Oh Sang-Cheol
Published: April 2024

This study compared the characteristics of welding rod consumption, welding time, and welding economy of welding rods of various diameters commonly used in shielded metal arc welding to select an appropriate welding method for structures. The results of the study revealed that for welding a test piece, an average of 3.5 rods was consumed for ø3.2-mm welding rods, while an average of 1.93 rods was consumed for ø4-mm welding rods. Converting the consumption to the cost of welding revealed approximately 601 KRW for ø3.2-mm welding rods and approximately 560.3 KRW for ø4-mm welding rods. Using larger ø4-mm welding rods reduced the cost by 40.7 KRW, which is equivalent to a 7.3% savings in rod welding expenses.

Published: April 2024

The livestock industry is closely associated with waste. On-farm waste such as beef cattle feces and off-farm waste in the form of dairy waste water solids can have detrimental effects on the environment if left untreated. The high nutrient content of livestock industry waste can be effectively utilized to prevent environmental pollution. However, the large amount of organic waste poses a significant challenge due to population density and the lack of land for waste storage or processing, which are unresolved issues. This waste can be processed through bioconversion, with the use of Black Soldier Flies (BSF) larvae representing a new method of organic waste treatment. This research was conducted at the Beef Cattle Teaching Farm and the Laboratory of Microbiology and Animal Husbandry Waste Handling, Faculty of Animal Science, Padjadjaran University. The objective of this study was to investigate the impact of combining beef cattle feces, dairy waste water solids, and kitchen organic waste on the weight and density of maggot populations. The experimental method employed four treatments with five replications each: 100% kitchen organic waste (P0), 50% kitchen organic waste and 50% beef cattle feces (P1), 50% kitchen organic waste and 50% dairy waste water solids (P2), and 33.4% kitchen organic waste, 33.4% beef cattle feces, and 33.4% dairy waste water. The conclusion drawn from this study is that the combination of kitchen organic waste and beef cattle feces contributes to an increase in maggot population density.

Authors: Maddu Sai Naga Veera Bhadra Rao  , Nunna Sai Gowtham
Published: April 2024

In recent years, there has been a growing demand for automated currency recognition and value detection systems to streamline the processes of cash handling and financial transactions. Image processing techniques have emerged as a promising approach to automate these tasks. This paperwork presents an efficient currency recognition and value detection system based on image processing techniques. The proposed system aims to automate the currency recognition and value detection process, which is an essential task in many financial and retail applications. The system consists of several stages: image acquisition, image pre-processing, feature extraction, image augmentation, and classification. The system uses several image processing algorithms, including data augmentation to enhance the quality of the input images and extract the relevant features. These tasks involve identifying the denomination of a bank note or coin and determining its value. The experiments' results demonstrate the proposed system's effectiveness in real- world scenarios, which can significantly reduce the time and effort required for currency recognition and value detection. In conclusion, the proposed system achieves high accuracy and robustness in recognizing different currencies, including bank notes and coins, under various lighting conditions and orientations. The system's performance can significantly reduce the time and effort required for currency recognition and value detection, making it suitable for use in financial and retail applications. Future work will focus on improving the system's performance in more challenging scenarios, such as handling damaged or counterfeit currency.

Anti Ma 2 encephalitis is an autoimmune encephalitis, usually paraneoplastic, characterized by isolated or combined limbic, diencephalic, or brainstem dysfunction. It most commonly affects males with testicular or small cell lung cancer, though cases have been reported in females with gynecologic malignancies [1]. We describe an unusual presentation of a paraneoplastic neurologic syndrome presenting with predominant involvement of the hypothalamus and deep grey nuclei secondary to a testicular cancer associated with anti-Ma2 antibody.
Maailma tuhon jälkeen
Authors: Nykänen Elise
Published: April 2024

Artikkelini tarkastelee dynaamisen utopian keinoja ja tehtäviä Siiri Enorannan nuortenromaanissa Maailmantyttäret (2022). Suomalaisessa nykykirjallisuudentutkimuksessa utopiaa on tutkittu ensisijaisesti suhteessa dystopiaan. Kyseenalaistaessaan käsityksen utopiasta staattisena ihanneyhteiskuntana osa utopiatutkijoista on kritisoinut käsitystä utopiasta väistämättä totalitarismiin johtavana visiona. He ovat lähestyneet utopiaa spekulaationa, joka nykyhetkeä kritisoidessaan esittää täydellistymän sijaan vaihtoehtoja vallitsevalle järjestelmälle.
Analyysini osoittaa, että Enorannan teos ilmentää feministisille nykyutopioille ominaista, muutosta lukijassa esiin kutsuvaa dynaamisuutta, joka ilmenee monien minäkertojien ääniä yhdistävässä kerrontatilanteessa ja lukijapositioiden moneudessa. Maailmantyttäret nojaa yhteiskunnalliseen unelmointiin vilpittömästi osallistuvan tekijän empaattiseen viestintään. Dynaamisen utopian pyrkimyksenä on valaa nuoriin (vähemmistö)lukijoihin tulevaisuudenuskoa ja kutsua esiin erimielisten välistä diplomatiaa. Nykyaikakritiikin osalta teos hyödyntää affektiivis-retorisina keinoina vieraannuttamista, satiiria ja ironista etäännyttämistä. Esitän, että vaihtoehtona dystopian vaikuttamisen keinoille teos korostaa kollektiivisen unelmoinnin merkitystä: tuhon kuvitteleminen ja siitä varoittaminen eivät tuota toivottua tulosta yhteiskunnallisen muutoksen aikaansaamiseksi, sillä usko sosiaaliseen muutokseen ennakoi muutosta edistäviä tekoja.

Published: April 2024

The reliability of numerical simulation of crack growth in a laminate glass-epoxy composite under mixed-mode loading by opening (mode I) and shear (mode II) of an interlayer crack is verified. According to the experimentally determined standard (DCB and ENF) and nonstandard (SLB and OLB) methods, the values of the parameters of interlayer crack resistance under individual and mixed-mode loading modes I and II calculated the exponent in the Benzeggagh-Kenane equation as a material constant of the laminate epoxy glass composite. Using this parameter and the ANSYS software package, within the framework of linear elastic fracture mechanics and the method of virtual crack closure, numerical finite element modeling of the growth of interlayer cracks in samples of a laminate glass-epoxy composite of the SLB and OLB types was carried out under a mixed-mode loading with a different fraction of modes. With the optimal number of elements in the finite element mesh per given length of the crack growth trajectory, numerical simulation provides sufficient accuracy of calculations of the limit load of the beginning of crack growth with a minimum amount of calculations and good agreement between the experimentally determined and calculated crack resistance parameters.

Published: April 2024

Effective educational cinema techniques can be employed in group guidance sessions for junior high school students, aiming to enhance their altruistic attitudes. This study seeks to assess the efficacy of utilizing educational cinema techniques in group guidance to promote altruistic behavior among junior high school students. Employing a quantitative approach, this research adopts a quasi-experimental design with a nonequivalent control group. Purposive sampling is applied to select male and female students aged 13-14 in classes VIIIC and VIIID at SMP Negeri 2 Negara, with a focus on those demonstrating a medium-level altruistic attitude. Data collection involves construct validity and Cronbach's Alpha reliability. Descriptive analysis, encompassing mean value, standard deviation, maximum, and minimum values, is employed for data analysis. Hypothesis testing utilizes the Wilcoxon test and the Mann-Whitney test. The Wilcoxon test yields a result of 0.027 < 0.05 for both the control and experimental groups, supporting the acceptance of the hypothesis. The Mann-Whitney test reveals a result of 0.015 < 0.05, indicating a significant difference in altruistic attitudes between the experimental and control groups. In conclusion, group guidance incorporating educational cinema techniques proves effective in fostering altruistic attitudes among junior high school students.

Authors: Nasir Nur Indah Ririn Fitriani , Arifin Slamet , Damopolii Insar
Published: April 2024

This research aims to analyze primary school students' motivation to learn science. Differences in student grades and gender were also examined in this research. The research has used survey methods. The survey was carried out on 97 students at one of the elementary schools in Malang City. The students who participated were those in grades 4, 5 and 6. A questionnaire containing 35 statement items measured students' motivation toward science learning. The analysis uses ANOVA to measure differences in motivation based on grade, gender, and interactions between grade and gender. There is no influence of grade and gender on students' motivation to learn science. On average, students' science learning motivation is good. Female students dominate the overall motivation score (M), active learning strategies (ALS), self-efficacy (SE), performance goal (PG), and science learning value (SLV), while Achievement goal (AG) and learning environment stimulation (LES) dominate the male student scores. The student's PG was weak. This indicates that students study science not to improve their performance but to get attention and be considered the best by others.

Published: April 2024

This paper explores the integration of machine learning with adaptive
theory in social science research, highlighting a methodological
evolution crucial for understanding complex social phenomena. I examine
the synergistic potential of combining machine learning’s data-driven
analysis with adaptive theory’s iterative, flexible nature. The paper
outlines the methodological fit of adaptive theory in social sciences,
emphasizing its accommodation of complexity and contextual variability.
I discuss the theoretical implications of incorporating machine
learning, including its role in hypothesis testing and the development
of social theories. The paper further navigates through the research
process, illustrating how initial broad concepts refine into structured
inquiries via inductive exploration and deductive forecasting using
machine learning techniques. Finally, I address the challenges and
opportunities presented by this integration, such as model
interpretability and ethical considerations, while forecasting future
research directions. This integration marks a significant step in
enhancing the depth, dynamism, and responsiveness of social science
methodologies.
Early caregiver predictability shapes neural indices of statistical learning later in infancy

Published: April 2024

Caregivers play an outsized role in shaping early life experiences and development, but we often lack mechanistic insight into how exactly caregiver behavior scaffolds the neurodevelopment of specific learning processes. Here, we capitalized on the fact that caregivers differ in how predictable their behavior is to ask if infants’ early environmental input shapes their brains’ later ability to learn about predictable information. As part of an ongoing longitudinal study in South Africa, we recorded naturalistic, dyadic interactions between 103 (46 female, 57 male) infants and their primary caregivers at 3-6 months of age, from which we calculated the predictability of caregivers’ behavior, following caregiver vocalizing and overall. When the same infants were 6- 12-months-old they participated in an auditory statistical learning task during EEG. We found evidence of learning-related change in infants’ neural responses to predictable information during the statistical learning task. The magnitude of statistical learning-related change in infants’ EEG responses was associated with the predictability of their caregivers’ vocalizations several months earlier, such that infants with more predictable caregiver vocalization patterns showed more evidence of statistical learning later in the first year of life. These results together suggest that early experience with caregiver predictability shapes learning in the matching sensory modality, providing support for the hypothesis that the neurodevelopment of core learning and memory systems is closely tied to infants’ experiences during key developmental windows.
Distortion of Overlapping Memories Relates to Arousal and Anxiety
Authors: Morrow Erin , Clewett David
Published: April 2024

Everyday experiences often overlap, challenging our ability to maintain distinct episodic memories. One way to resolve such interference is by exaggerating subtle differences between remembered events, a phenomenon known as memory repulsion. Here, we tested if repulsion is influenced by emotional arousal, when resolving memory interference is perhaps most needed. We adapted an existing paradigm in which participants repeatedly studied object-face associations. Participants studied two different colored versions of each object: a to-be-tested ‘target’ and its not-to-be-tested ‘competitor’ pairmate. The level of interference between target and competitor pairmates was manipulated by making the object colors either highly similar or less similar, depending on the participant group. To manipulate arousal, the competitor object-face associations were preceded by either a neutral tone or an aversive, arousing white noise burst. Memory distortion for the color of the target objects was tested after each round of learning to examine if memory distortions gradually emerge over time. We found that participants with greater sound-associated pupil dilations, an index of physiological arousal, showed greater memory attraction of target colors towards highly similar competitor colors. Greater memory attraction was also related to greater memory interference at the end of learning. Additionally, individuals who self-reported higher trait anxiety showed greater memory attraction when one of the memories was aversive. Our findings suggest that memories of similar neutral and arousing events may blur together over time, especially in individuals who show higher arousal responses and symptoms of anxiety.
The attitudes at the heart of multilingual family language policies

Published: April 2024

Family language policies encompass three components: language beliefs, language practices, and language management. This study focuses on language beliefs, which we approach from an attitudes perspective, presenting a corpus-assisted discourse study of parental attitudes towards childhood multilingualism. Based on corpora (over 30,000 words) comprising 742 Quebec-based parents’ responses to an open-ended survey question, we analyse frequencies, collocations, concordance lines, and longer text segments. Our findings confirm the multidimensionality of parental attitudes, providing new insights into the nature of the three previously-established dimensions – that is, status, solidarity, and cognitive development – as well as revealing a potential fourth dimension: namely personality development. Moreover, the findings show systematic differences between parents transmitting multiple societal languages versus parents transmitting heritage languages alongside one/more societal languages. The study makes an important contribution to the family language policy framework and language attitude theory more generally, and it facilitates the development of support measures for different types of multilingual families.
The Cognitive Precursors of Early Developing Essentialist Beliefs
Authors: Wang Michelle Momo , Xu Yian , Moty Kelsey , Rhodes Marjorie
Published: April 2024

Essentialist beliefs about categories (e.g., intuitions that categories like “girl” or “tiger” reflect real natural structure in the world) emerge early in development across diverse cultural contexts, but the processes by which they develop have rarely been examined. We tested if the basic conceptual and explanatory biases that children rely on to build intuitive theories of the world contribute to the emergence of essentialism across early childhood. Consistent with this possibility, children who deferred to experts regarding category labels, endorsed single and intrinsic causes for object functions, and generated over-hypotheses about structure based on limited evidence developed more essentialist beliefs across childhood (with some variation across domains of thought). Together, these data reveal that the development of essentialist beliefs is shaped by basic conceptual biases that underlie how children construct intuitive theories about the world.
A photometric study of early-type dwarf galaxies in the Virgo cluster
Authors: Mohammed Khalid
Published: April 2024

A photometric study is carried out for a sample of early-type dwarf galaxies in the Virgo cluster. These include dwarf ellipticals (dEs), nucleated dwarf ellipticals (dE(N)s), and dwarf lenticulars (dS0s). The color-magnitude relations (CMRs) of these types are studied in various photometric passbands. The CMR slope and scatter of dEs and dE(N)s are found to be very similar, indicating having similar origins. However, the CMR of dS0s are found to be steeper and tighter than those of dEs and dE(N)s, which indicate that dS0s have different stellar populations, with the existence of star formation activity.

Derivation of a simple engineering equation for the minimum voltage of inverted fireball onset
Authors: Gruenwald Johannes
Published: April 2024

This paper describes the derivation of a simple engineering equation to calculate the minimal necessary bias voltage for the onset of an inverted fireball. The calculation uses the electron density in the absence of an inverted fireball as well as the grid constant and the working gas species as input parameters. It will be shown that the interplay between ionsation potential, dissociation potential (for molecular working gases), as well as the electron density in the background plasma, play an important role in the necessary minimum bias on the fireball electrode. Some of the most common working gases and their relevant parameters will also be listed in this paper. This should give experimentalists and engineers a practical equation that can be used to quickly determine the most important electrical properties of the anode that is used to trap the inverted fireball. Thus, the planning and design of experimental setups or technological devices will be made much less time-consuming and, thus, more convenient.
CRiTical Race Information Theory as Innovative Pedagogy, Act Two: Still Harder Than You Think, and It Remains a Beautiful Thing
Authors: Dunbar Anthony W. , McFarland Rebekah , Grauel Elizabeth
Published: April 2024

This counterstory began with “CRiTical Race Information Theory as Innovative Pedagogy, Act One: Harder Than You Think, It's a Beautiful Thing.” In the first act, the authors introduced Critical Race information Theory (CRiT) as a rapidly developing iteration of Critical Race Theory (CRT) applied within information settings. The first act also introduced the CRiT frameworks and tenets as well as the CRiT's three-dimensional infrastructure: CRiT as pedagogy, CRiT as praxis, and CRiT as theory (including the process and nuances of theory building).

In this article, the authors transition from the first act's “What is CRiT?” discussion to the second act's discussion of how to “Make it CRiT.” Whereas act one covered an approximately 15-year period, this second act moves at a more rapid pace, primarily because it covers a shorter period of time (2021–2023). In act two, the CRiT as pedagogy setting changes from the context of the pilot course launched within the Department of Information Studies at the University of California, Los Angeles to CRiT as pedagogy providing two offerings to Dominican University's School of Information Studies foundational course electives in its ALA-accredited curriculum. Before concluding, the second act offers inspiration and encouragement both to those who offer their critical race work as expressions of transformative, difference-making contributions and to those who aspire to develop and then offer their critical race creations.

The article reviews the literature on the impact of the Internet on university communication, focusing on the integration of social media. It highlights the importance of the Social Media Plan (PMS) and the role of the community manager in Spanish universities. However, it is pointed out that current management does not reach the desired standard due to lack of support, weaknesses in the communication departments, and scarcity of resources. The need for an effective strategy is emphasized. The importance of directing efforts toward the target audience, creating relevant content, and encouraging interaction to build a valued community is highlighted. Expert management and the development of a content plan are recommended.

From 1893 to 1905, the values of the geomagnetic field recorded three times a day are available from the Ógyalla magnetic observatory. We introduce these unique records, and at the same time, we provide an analysis of three noteworthy magnetic storms from this period, namely the events on 30 March 1894, 9 September 1898, and 31 October 1903. In addition to violent magnetic variations, remarkable auroras were observed in Central Europe during these events. The analysed events indicate that the source of the most intense, potentially dangerous geomagnetic disturbances can be the electric currents of the auroral oval or the field-aligned currents connected to the auroral oval.

When producing water using desalination technologies, significant volumes of highly concentrated brines are formed. The solution of the problem of wastes recycling is an important global issue for water protection organizations, and the studies of the last decade confirm this. The article discusses an environmentally friendly method of dispersed uniform brine discharge into the water area, presents the developed technical solution and describes the principle of its operation. As an example, the authors calculate the hole diameters of the distribution pipeline for uniform brine discharge along the length. We calculated the radius and the scattering jet rate at a given distance from the hole in the distribution pipeline. The difference in brine salt concentrations at a depth of 20 m from the discharge point between the background concentration in the sea and the salt concentration was found to be from 0.439 % to 0.524 % along the length of the discharge pipeline. Dissolution of brines to safe concentrations becomes even more intense in the presence of sea currents. The research results can be used in the design and operation of such systems.

The use of microorganisms that stimulate the precipitation of carbonates, which can fill the cracks that form in the structure of cementitious composites [MICP], has been gaining interest in recent years as an alternative method of self-healing of these materials. This article analyses the effectiveness of surface application of repair agents composed of zeolite NaX and bentonite, Bacillus subtilis bacteria spores and cementing solutions [precursors of precipitation reactions] as a method of repairing cracked cement mortar surfaces. The effects of this method were evaluated by image analysis and microstructure studies of precipitates precipitated under controlled conditions and on the surfaces of healed composites. Raman spectroscopy and X-ray diffraction were used to characterize the microstructure. The conducted tests confirmed the precipitation of carbonates in the breakthrough of the healed cracks [maximum 31.9% occupation of the surface by the precipitate produced], which proves the effectiveness of the MICP process incident, at the same time indicating the participation in the mechanism of abiotic precipitation of crystalline forms present in the cementing solutions. Additionally, the effectiveness of using Raman spectroscopy to characterise the surface of the cement composite and the carbonates precipitated by microorganisms was confirmed.

Background: Dementia is prevalent among the elderly, also representing a risk for seizures/epilepsy. Estimations of epilepsy risk in dementia patients are not widely available. Objective: Our research aims to ascertain the incidence of epilepsy and its associated risk factors in subjects with dementia in the Umbria region, based on data from healthcare databases. Methods: In this retrospective study based on the healthcare administrative database of Umbria, we identified all patients diagnosed with dementia from 2013 to 2017, based on ICD-9-CM codes. For epilepsy ascertainment, we used a validated algorithm that required an EEG and the prescription of one or more anti-seizure medications post-dementia diagnosis. A case-control analysis was conducted, matching five non-dementia subjects by gender and age to each dementia patient. Cox proportional hazards models were then utilized in the analysis. Results: We identified 7,314 dementia cases, also including 35,280 age- and sex-matched control subjects. Out of patients with dementia, 148 individuals (2.02%) were diagnosed with epilepsy. We observed a progressive increase in the cumulative incidence of seizures over time, registering 1.45% in the first year following the diagnosis, and rising to 1.96% after three years. Analysis using Cox regression revealed a significant association between the development of epilepsy and dementia (HR = 4.58, 95% CI = 3.67–5.72). Additional risk factors were male gender (HR = 1.35, 95% CI = 1.07–1.69) and a younger age at dementia onset (HR = 1.03, 95% CI=1.02-1.04). Conclusions: Dementia increases epilepsy risk, especially with early onset and male gender. Clinicians should have a low threshold to suspect seizures in dementia cases.

In this work, the image block matching based on dissimilarity measure is investigated. Moreover, an unsupervised approach is implemented to yield that the algorithms have low complexity (in numbers of operations) compared to the full search algorithm. The state-of-the-art experiments only use discrete cosine transform as a domain transform. In addition, some images were tested to evaluate the algorithms. However, these images were not evaluated according to specific characteristics. So, in this paper, an improved version is presented to tackle the problem of dissimilarity measure in block matching with a noisy environment, using another’s domain transforms or low-pass filters to obtain a better result in block matching implementing a quantitive measure with an average accuracy margin of ± 0.05 is obtained. The theoretical analysis indicates that the complexity of these algorithms is still accurate, so implementing Hadamard spectral coefficients and Fourier filters can easily be adjusted to obtain a better accuracy of the matched block group.

Optimal weight support vector regression ensemble with cluster-based subsampling for electricity price forecasting
Authors: Li Yuerong , Zhang Yuhua , Che Jinxing
Published: April 2024

Accurate prediction of short-term electricity price is the key to obtain economic benefit and also an important index of power system planning and management. Support vector regression (SVR) based ensemble works have gained remarkable achievements in terms of high accuracy and steady performance, but they are highly dependent on data representativeness and have a high computational complexity O (k * N 3) of data samples and parameter selection. To further improve the data representativeness and reduce its computational complexity, this paper develops a new approach to forecast electricity price via optimal weighted ensemble. In the model, the cluster-based subsampling algorithm is proposed to categorize the inputs being seasonally decomposed into several groups, and representative data are drawn from each group in a certain proportion to ensure that each subset trained with SVR has the same representativeness and features. Moreover, the optimal weighted combination method is presented to assign weights to the sub-SVRs to obtain the optimal support vector regression ensemble model (OWSSVRE). The experimental results show that the improved support vector regression ensemble model with the same features and representativeness of the subset has better performance in electricity price forecasting. As a result, it is suitable to support decision making in the energy and other sectors.
