Authors: Dulkadir Yaman Nihal
Published: January 2025

Chatbots have emerged as an important development in the field of human-computer interaction in recent years. Designed using natural language processing and machine learning technologies, these artificial intelligence-based programs can understand users' questions and requests and respond instantly. Chatbots, which are used in various fields ranging from education to customer service and healthcare to sales and marketing, offer important opportunities in education such as learning management, personalized learning, learning support. However, there are a number of limitations in the use of this technology. For example, an inability to interact as real people would, the risk of providing false information, ethical issues, and an inability to provide a personalized learning experience. Therefore, more research and development studies are needed for the effective use of chatbots in education. Within the scope of this study, pre-service teachers' views on the use of chatbots in education were examined. In this direction, the participant group of the research, which was conducted at a state university in the fall semester of 2022-2023, consisted of 41 pre-service teachers studying in the Department of English Language Teaching and the Mathematics Education who attended the Instructional Technologies course. In the study, data were collected with a data collection tool consisting of two parts. The participants saw the advantages of chatbots, such as timesaving and providing different information. However, negativities such as utilizing unexpected sources were also emphasized. In general, most of the pre-service teachers found chatbots successful in terms of language and content. The pre-service teachers stated that chatbots will be widely used in education in the future and that they will direct their students to this technology. In conclusion, for chatbots to be used effectively in education, they need to be designed in accordance with student needs, provide accurate and up-to-date information, offer personalized learning experiences, and be supported by educational experts. In this way, chatbots can become a more effective tool in education.

Published: January 2025

Introduction: Given the multitude of climate changes and the varying level of adaptation in different societies, it is necessary to measure the degree of adaptation to climate change in any society, as these aids in planning strategies to promote adaptation. Achieving such a goal requires the use of reliable, stable, and indigenous culture-based tools. The purpose of this study is to design and psychometrically assess the adaptation of Iranian society to dust. Materials and methods: The present investigation is a sequential exploratory combined study that utilizes an instrumentation approach. The primary tool, consisting of 101 design items, was developed Based on indicators extracted from two qualitative studies and a systematic review. Its face (quantitative and qualitative), content (qualitative and quantitative), and structural validity among 432 citizens of Ahvaz in southwest Iran were evaluated using exploratory factor analysis. The reliability of the tool was then calculated using Cronbach's alpha test and the intra -cluster correlation index.
Results: After calculating the item effect score index with values higher than 1.5, the content validity ratio higher than 0.49, and the content validity index higher than 0.79, 40 items out of the initial 101 were selected. Through exploratory factor analysis, the items were further reduced to 34 and grouped into four areas, based on the eigenvalue being higher than 1. The tool's reliability was confirmed with a Cronbach's alpha of 0.974 and an Intra- Cluster Correlation index (ICC) of 0.951 with a 95% confidence interval.
Conclusion: This study successfully designed and produced a tool for measuring the adaptability to dust, comprising 34 items categorized into four areas: optimistic capacity, adjustment, adaptation, and response. This tool can quantitatively measure society's adaptability to dust. With its strong validity and reliability, the tool can identify both the weakness and strengths of a society's adaptation to dust, compare the level of adaptation across different societies, and determine trends within a society.

Authors: Eghomwanre Aimuanmwosa Frank , Edomwonyi Gracious Oghosa
Published: January 2025

Introduction: The singeing of animals is one of the major sources of human exposure to air pollutants in abattoirs especially in developing countries and it can cause various adverse health effects among the workers. This study assessed the concentrations of particulate matter in selected abattoirs and examined the associated health risks among the workers in Benin City, Nigeria.
Materials and methods: Measurements of Particulate Matter (PM2.5 and PM10) were performed in three areas in the abattoirs for three months, and
the noncarcinogenic risks of exposure to PM2.5 and PM10 were determined via Hazard-Quotients (HQs) and Hazard Indices (HIs). The occurrence and relationship between the reported risk factors and health effects among abattoir workers were also examined using the modified American Thoracic Standard (ATS) respiratory symptoms questionnaire.
Results: The levels of PM2.5 and PM10 in the hide roasting areas were significantly higher (p>0.05) than those at other sampling points across the abattoirs. The indoor and outdoor ratio (I/O) of the particulates was greater than 1.0 in almost all the abattoirs. The concentrations of PM2.5 and PM10 were higher than the permissible air quality standards. The HQ values exceeded 1.0 in all the sampling areas, implying that exposure to particulate concentrations could result in adverse health effects in abattoirs. The chi-square test revealed significant associations between reported risk factors such as: age, work experience, duration of exposure, and use of Personal Protection Equipment (PPE) and health effects (dry cough, eye irritation, asthma, difficulty breathing, sore throat, and chest pain) among abattoir workers.
Conclusion: This study revealed that hide roasting at abattoirs results in poor air quality in the abattoir environment and contributes to adverse health effects among workers.

Authors: Momen Ali , Rezaei Arezo , Rostami Roohollah
Published: January 2025

This review evaluates metal concentrations in indoor air within residential buildings, focusing on original research published in English from 2010 to 2022. We conducted a comprehensive literature search across Google Scholar, ScienceDirect, and SpringerLink, identifying 34 relevant studies measuring metal concentrations in various residential environments. Data extraction revealed significant regional variations, with urban homes exhibiting higher metal concentrations compared to rural and industrial areas. Chromium (Cr) levels in urban regions reached 116.00±170.00 mg/kg, compared to 63.40±34.80 mg/kg in rural areas and 30.90±16.90 mg/kg in industrial regions. Nickel (Ni) concentrations were also higher in urban homes at 86.10±126.00 mg/kg, versus 27.60±9.08 mg/kg in rural and 20.40±7.65 mg/kg in industrial settings. The living room showed the highest metal concentrations, with lead (Pb) at 170.00±NA mg/kg and nickel (Ni) at 174.00±144.00 mg/ kg, significantly higher than in bedrooms and kitchens (p<0.05). Seasonal variations indicated elevated warm season metal concentrations, with iron (Fe) measured at 11,200 ± 9830 mg/kg. Health risk assessments highlighted a total cancer risk (CR) of 1.59 × 10⁻³ in industrial areas, exceeding acceptable limits (10⁻5 to 10⁻⁶). The ingestion pathway was the primary route for both cancer and non-cancer risks, with copper (Cu) posing the highest potential cancer risk across all regions. These findings emphasize the need for monitoring and regulation of indoor metal concentrations, particularly in industrial areas.
The Application of Artificial Digital Models in X-Ray Computed Tomography (CT) of the Core in Solving the Problem of Binarization of the Void Space of Reservoir Rocks
Authors: Melkishev O. A. , Savitsky Y. V. , Galkin S. V.
Published: January 2025

The X-ray tomography method has several advantages, including its non-destructiveness and the ability to visualize the rock skeleton and pore space in three dimensions. However, one of the main challenges of this method is the limited resolution when studying core samples that are 30 millimeters in diameter, which is typical for petrophysical analysis. In these samples, a significant portion of pores have dimensions smaller than the resolution capabilities of most X-ray tomographic systems, making it impossible to accurately determine the boundary between the pore and skeleton structures in tomograms, nor visualize the entire pore volume.

To verify this hypothesis, tomograms from real oil and gas samples were analyzed. The resulting histograms of X-ray densities revealed that it is not possible to directly measure the threshold value of X-ray density that defines the “skeleton-pore” boundary. In order to solve the problem of estimating boundary values, a technique is proposed in this work that suggests using artificial digital models – phantoms. This approach has been previously used mainly in computer modeling, but it has not been used much in petroleum geology. The main advantage of using phantoms is complete control over the set pore space parameters and X-ray density of the skeleton, which cannot be achieved on real samples.

A computational experiment was conducted in the work, where 124 core phantoms with specific porosity characteristics were generated using numerical modeling. These phantoms were then converted into tomograms, allowing us to determine statistical characteristics of the values for X-ray densities of the samples at the reconstruction stage.

Based on the statistical analysis of the X-ray density distribution in the sample, we determined the boundary values that are most suitable for reliable void space detection. Using regression and correlation methods, we developed a model to estimate the optimal boundary value for X-ray density in void space allocation.

We proposed an algorithm for determining and applying this value in the analysis of core X-ray CT data.This model was tested on real samples that were not used in the development of the forecast model. The use of the proposed model for predicting boundary values on obtained tomograms demonstrated a high degree of consistency with actual data.
Organic Geochemistry of Bituminous Shales in the Kashpirskoe field (Samara region)
Authors: Timoshina I. D. , Ivanova E. N.
Published: January 2025

The studied Upper Jurassic and Lower Cretaceous bituminous shales of the Kashpirskoe field contain organic matter (OM) terrestrial in carbon isotopic composition (δ13C > –24‰) and marine in pyrolytic characteristics (HI > 500 mg HC/g TOC). Shales contain autochthonous bitumens that are marine (Pr/Ph ≤ 0.5, Ph/nC18> 1, distribution of biosteranes with C29/C27 ≤ 1.5, presence of long-chain alkyl naphthalenes – indicator of marine algae Gloeocapsomorpha prisca, “V-shaped” distribution of methyldibenzothiophenes). At the same time, a number of parameters correspond to the terrestrial OM (in n-alkanes nC27/nC17 >>1, Pwax (0.6–0.7) > Paq(0.4–0.5), the indicator of coniferous plants reten is marked in the aromatic fraction), which indicates the proximity of land. Isorenieratene derivatives, biomarkers of specific Chlorobiaceae bacteria, were found in the samples; therefore, despite the probable proximity of land, anoxia occurred in the photic layer of the sedimentation basin. The presence of diasterenes indicates diagenetic transformations also under conditions of anoxic sediment. According to the results of pyrolysis, the OM is catagenetically weakly mature (very low Tmax), which is confirmed by the composition of the bitumen (CPI ≥ 1.7 in n-alkanes, high Pr/nC17 and Ph/nC18 ratios, absence of isoand diasteranes, presence of biosteranes and sterenes, low concentrations or absence of typical terpanes, presence of biohopanes and hopenes, low the ratio of homohopanes C3122S/(22S+22R) << 0.5, low ratios of MDR (0.5–1.0) and MPI-1 (0.4–0.8), mostly absent (not yet formed) monoand triaromatic steroids).

The Lower Cretaceous shales from the boundary interval between the Volgian and Ryazan stages, not characterized by fauna, are more enriched in terrestrial components compared to the Upper Jurassic oil shales from the Dorsoplanites panderi ammonite zone. The peculiarities in the characteristics of the studied shales are associated with the genetic specificity of the OM, with anoxia in water and sediment with the accumulation of OM, and with its weak catagenetic maturity at fairly high concentrations.

The paper presents the results of nuclear magnetic resonance (NMR) study of oil samples taken from production wells from the fields of the Republic of Tatarstan before and after the application of one of the enhanced oil recovery (EOR) methods, namely, flow rejection technology based on injection of microgel compositions into injection wells. A comparative analysis of proton NMR spectra and diffusion attenuation of spin echo in spectrally resolved mode was carried out in order to determine the influence of the used technology on the characteristics of recoverable oil. It is shown that after application of EOR for the majority of wells in the oil composition an increase in the share of hydrocarbon components with large values of molecular weight is registered, and for a number of wells a change in the degree of aromaticity of recoverable hydrocarbons is also recorded. The results obtained are interpreted as a consequence of the inclusion in the development of new reservoir zones, previously not involved in oil production, and demonstrate the potential of NMR method for assessing the efficiency of EOR.

Published: January 2025

A finite-element scheme has been developed, including a section of reservoir rock, cement stone, casing and perforation channels. It is noted that in order to exclude the occurrence of stress concentrators at the casing – cement stone and cement stone – rock contacts, contact elements are specified in the numerical model, due to this, structural elements «slip», but at the same time, a reliable redistribution of stresses is carried out. Numerical simulation of the stress state of the near-wellbore zone using the developed model with varying depression on terrigenous reservoir for the conditions of one of the Perm Region oil field is carried out. It is shown that the safety factor of the casing is about 3–4 units, with the exception of small areas near the upper and lower areas of the perforations, where this indicator is close to one. For cement stone, the safety factor was 2-3 units and however, areas with its lowest value (1.35), also concentrated near the perforation channels, were note. To analyze the change in permeability, the dependence of this characteristic on effective stresses was used and it was found that zones of reduced stresses and an increase in permeability up to 20% of the initial value are detected in the upper and lower parts of the perforations. With an increase in depression on the reservoir, permeability decreases, especially in the lateral sections of the holes, where this parameter can decrease by 25% of the initial value. Using the Coulomb-Mohr criterion, areas of rock destruction from stretching and compression were identified. It is noted that with increasing depression, the areas of destruction under tensile stresses disappear and the areas of destruction under compression increase. An analysis of the change in the productivity coefficient depending on the depression showed that when creating a maximum depression on the 12 MPa formation, the productivity coefficient of the well can decrease by 15% due to compaction of the reservoir rock caused by an increase in effective stresses.

This study aimed to characterize the aromatic uniqueness of Zelen (Vitis vinifera L.) wines, an authoctonous variety from Vipava Valley located in Western Slovenia, through chemical and sensory assessment. Seventy aromatic compounds, including varietal thiols, esters, C6-alcohols, volatile phenols, terpenoids, and norisoprenoids, were analyzed by HS-SPME-GC-MS in two surveys comparing Zelen wines with four other varieties grown in Vipava Valley. The olfactory space of Zelen wines was defined by comparing their aromatic profiles with those of Pinela wines in a sorting task and by HPLC-olfactometry. Zelen wines were characterised by dried herbs and spicy notes such as thyme, rosemary and basil in comparison to Pinela wines. The chemical profile of Zelen wines was dominated by the presence of an original mixture of monoterpenes, including terpinene isomers, limonene, p-cymene, terpinolene, linalool, and α-terpineol, as well as volatile phenols, 4-vinylguaiacol, and methyl salicylate. The obtained concentrations of 4-vinylguaiacol and methyl salicylate were at levels close to or above the reported olfactory threshold, thus inferring a potential contribution of these compounds to the spicy aromatic components of Zelen wines. Two aromatic fractions reminiscent of herbal notes specific to Zelen wines - isolated by HPLC semi-preparative fractionation and further analysed by HS-SPME-GC-MS - revealed the presence of an original mixture of hydrocarbon monoterpenes, including the compounds that were quantitatively measured, and others, such as β-myrcene, β-phellandrene, E-β-ocimene, Z-β-ocimene, and two 2,4,6-octatriene-2,6-dimethyl isomers. Semi-quantitative measurements showed that this new group of monoterpenes was also present at higher levels in Zelen than in Pinela, Malvasia Istriana, Chardonnay, and Sauvignon blanc wines.
Clinical Indicators for Evaluating Japanese Public Hospital Performance: Changes after the Epidemic Phase of Novel Coronavirus Infection
Authors: Moteki Yasutoshi
Published: January 2025

Aim
This study investigates the adoption and implementation of clinical indicators in Japanese public hospitals, focusing on changes since the coronavirus disease 2019 pandemic and utilizing Donabedian's triadic model (structure, process, outcome).
Subject and Methods:
A nationwide postal survey was conducted targeting 848 municipal hospitals with ≥ 20 beds in Japan. The survey explored clinical indicator usage, categorized by Donabedian’s framework. Hospitals were classified based on size to evaluate disparities in indicator adoption. Data were analyzed to compare findings from the current 2024 survey with a similar 2016 survey.
Results
The response rate was 15.7%, with 130 valid responses. Clinical indicator adoption increased from 42.4% (2016) to 58.5% (2024). Large hospitals were more likely to implement clinical indicators (88.1%) than small and medium hospitals (27.0%). Frequently used indicators included average hospitalization duration, bed utilization rates, and clinical pathway coverage. Each structural indicator remained underutilized, with < 15% of hospitals reporting their use.
Conclusion
The findings highlight progress in clinical indicator adoption, particularly in large hospitals. However, significant disparities persist between hospital sizes. As the pandemic subsides, it remains essential to continue improving hospital management practices, including clinical indicator use, in preparation for future infectious disease outbreaks. The three-way model classification for medical evaluation is renowned, but the percentage use of structural indicators has not exceeded 15%, and the implementation status is not as advanced as that of process and outcome indicators. Our results are significant as they verify the explanatory power of the three-way model for medical care based on Japanese data.

Published: January 2025

This study describes the preparation of clay/polymer composites using Bijoypur clay (kaolinite) and copolymer poly(hydroxyethylacrylamide-co-3-methacryloxypropyltrimethoxysilane) (poly(HEAA-co-MAPTS)) for the removal of organic dyes from industrial wastewater. The copolymer was prepared by free-radical polymerization of hydroxyethylacrylamide (HEAA) and 3-methacryloxypropyltrimethoxysilane (MAPTS). The clay was activated and purified followed by modification with dodecylamine. FT-IR analysis confirmed successful modification of clay and incorporation of polymer and organoclay in the composites. TG analysis showed that the composite exhibited better thermal properties with increasing polymer percentage. X-ray diffraction analysis revealed that the crystalline size of the composites increased from 23.79 to 60.43 nm with the increasing percentage (1–4%) of polymer. SEM analysis of the composite with higher polymer percentage showed uniform porous structure. Adsorption study was carried out using methylene blue (MB) and acid black-172 (AB) dyes. The composites with higher polymer concentration showed better adsorption capacity for both MB (5.288 mg/g) and AB (6.696 mg/g) dyes in aqueous solution, at initial concentration of 25 ppm, 50 mg of dose, and pH of 10.1 for MB and 4 for AB. The developed composites exhibited adsorption capability for both cationic and anionic dyes which gives a scope to their universal application in dye removal from industrial wastewater.

Authors: Hughes Stephen William , Schouten Peter
Published: January 2025

Data centres are considered the exclusive sites of information technology and computer science. However, many aspects of their day-to-day operation can be used to teach important concepts in physics, such as heat transfer, AC and DC power transmission, fibre optic transmission, energy loss in transmission cables, and electronic componentry. Data processing requirements and power usage in data centres are growing exponentially, and therefore, solutions need to be developed to reduce energy costs, given the challenges of global warming. To this end, work is being done on storing data in strands of DNA. An experiment to measure the change in temperature of air passing through an internet hub is described as a means of teaching students about the physics of data centres. The procedure and calculations shown in this particular experiment can be used and applied by secondary school physics students to evaluate the energy budget and efficiency of different data centres, such as those used at their school. In addition, this article details how students can make simple calculations that directly show how novel DNA data storage technology can be utilized to reduce the amount of hardware and power used at data centres. The potential for quantum computing to reduce the power requirements of data centres is also discussed.

This research is part of a larger project whose main purpose was to generate knowledge about part of the corpus of artistic cultural assets kept by the Museo de La Plata. The aim was to document this heritage and to deepen the study of the collection curator, to add historical and artistic content in support of the collection, in addition to locating it in space and time within the Historiography of local and national art. To this end, our interdisciplinary work integrated the contributions with historical, theoretical, methodological and technical content from the fields of Art History and Museology. Within this framework, we analyzed the only oil mural painting (1.86 x 3.28 m) by artist Pablo Matzel (-1926), made for the Museo de La Plata: The Mastodon and the Glyptodonts (ca. 1921). This analysis builds on the historical and cultural dimensions of the representation of prehistoric fauna, recovering the situations that brought about the encounter between the motif and the public. The mural by Matzel, whose works are mainly recognized in the field of scientific illustration, is inscribed in the naturalist tradition and is part of the Museum's collection, which entails reading the representations in the articulation between science and art. In the second half of the 19th century, any worthy museum needed to possess specimens of the gigantic fossil mammals from South America. The Museo de La Plata boasted an important variety of fossil remains of the true giants that Buenos Aires province could offer to the world. The work studied here expands this material dimension by presenting itself as a place to observe the construction and circulation of multiple and diverse knowledge types.

Published: January 2025

Population growth has increased demand and diversified use of Irish potato which have increased its demand. The crop has become a major source of food and income for many households across the world. However, despite the high potential of about 30 tonnes per hectare (ha), smallholder farmers in Kenya realize low Irish potato yields ranging from 4-8 tonnes per ha due to limited uptake of agricultural technologies. The low yields calls for a profound understanding of the factors influencing the uptake agricultural technologies. The study analyzed the effects of the adoption of agricultural technologies on Irish potato yield in Ol Kalou Sub County. The study considered chemical fertilizer, certified seeds, fungicides, and farm machinery as the four main agricultural technologies that that affect yield. A descriptive cross-sectional research design was used to obtain data from a study population of 21,942 smallholder Irish potato farmers in Ol Kalou Sub County. A multiple-stage sampling technique was employed to generate a sample size of 385 respondents who provided primary data. Data collected was analyzed using endogenous switching regression model using STATA version 17. The study found that the average treatment effect on treated (ATT) was 10.21 bags per acre. In addition, the Endogenous switching regression model showed that the expected yield for the adopter increased by 51.83%. Out of the four technologies, the use of chemical fertilizers had the highest effect of 37% on yield. The study concluded that the adoption of agricultural technologies increases the yield of Irish potatoes. The study recommends that national and county governments should develop policy regulations such as training and extension services, market access, price support and public-private partnerships encouraging farmers to uptake agricultural technologies. The study also recommends that both levels of government should subsidize agricultural technologies, hence reducing the cost of adoption.
Evaluating the Nutritional and Safety Aspects of Pyracantha coccinea: Antioxidant Activity, Mineral, and Heavy Metal Content
Authors: Görmez Gül
Published: January 2025

In this study, the fruits of Pyracantha coccinea, known for their ornamental and medicinal properties, were analysed to evaluate their antioxidant capacity, mineral content, and heavy metal concentrations. The antioxidant potential of Pyracantha coccinea was determined using DPPH, CUPRAC, and ABTS tests. Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES), Atomic Absorption Spectroscopy (AAS), and Gerthard Dumatherm techniques were used to determine the mineral and nutrient composition of the plant. As a result of the evaluation, calcium (0.25±0.02%), protein (4.29±0.47%), potassium (0.39±0.01%), magnesium (0.197±0.01%), sodium (0.08±0.01%), iron (0.012µg/g DW), aluminium (138±9.6 µg/g DW), cobalt (0.541±0.11 µg/g DW), chromium (0.422±0.05 µg/g DW), manganese (20±1.7 µg/g DW), zinc (43.9±4.6 µg/g DW), % DPPH (76.92±0.48) % ABTS value (77.52±0.39) and CUPRAC values (0.771±0.045 for 100ppm) were determined. In particular, the high levels of chromium (Cr) and zinc (Zn) in the fruits exceed the thresholds considered safe for medicinal applications and suggest that the heavy metal content in plants for medicinal use should be critically evaluated within acceptable limits. This study aims to explore the nutritional value and safety of Pyracantha coccinea by examining its antioxidant properties, mineral content, and potential heavy metal contamination. The findings will help shed light on its potential benefits and risks, offering valuable insight for its use in health, nutrition, and environmental applications.

Published: January 2025

The article is dedicated to the study of conventional promotion tools used for promoting brands in social networks in the context of increasing competition in the digital space, using the social network "VKontakte" as an example. The relevance of the topic is determined by the need to find effective approaches to promoting on social platforms in the international information market. Amid growing competition in the international media market and the increasing influence of social networks on political and social life, the methods and tools for their promotion remain insufficiently studied. The subject of the research is traditional advertising tools aimed at attracting new users and increasing engagement with the existing audience. The aim of the research is to determine effective approaches to promoting social networks, considering modern trends in digital marketing and communications. The materials of the study include examples of outdoor advertising and online banners used by the "VKontakte" social network. The research includes analytical and comparative analysis of traditional promotional methods applicable to the specifics of social networks, as well as content analysis of advertising materials. The novelty of the study lies in the identification of insufficiently studied aspects of promoting social networks as independent brands and the development of recommendations for their optimization. The results of the work can be applied both in strategic planning and the development of advertising campaigns for social platforms, and in educational and research projects dedicated to the phenomenon of digital communication. The social network "VKontakte" actively uses traditional methods of distributing advertising messages. The use of traditional advertising tools in the promotion campaign of the "VKontakte" social network shows that its developers understand the product and service orientation of the promoted object, using methods typical for the promotion of goods and services.

Beyond the Trenches

While World War I presented opportunities for women to break out of traditional roles, it also reinforced enduring gender norms. The war represents a complex period of both progress and regression for women’s rights and roles. This essay explores the impact of World War I on Canadian women, highlighting the tensions between the temporary expansion of their roles and the reinforcement of traditional gender dynamics. Prior to the war, women’s roles were largely confined to the domestic sphere, with limited participation in public or economic activities. However, as men left to fight, women took on jobs traditionally reserved for men, especially in clerical and industrial work, demonstrating their capabilities in new areas. Despite this, women’s contributions were often framed within the confines of traditional femininity, particularly in nursing, which reinforced the image of women as nurturers and caregivers. Propaganda during the war emphasized women’s caregiving roles, portraying them as saintly figures whose work in nursing aligned with societal ideals of female virtue and sacrifice. This reinforced the maternalistic view of women, even as they gained greater visibility in the workforce.
Crush Culture

This article examines the ways in which close relationships between women that previously had been deemed socially acceptable, and even encouraged, under early nineteenth century beliefs in separate gendered spheres, came under intense scrutiny at the turn of the twentieth century. The new social landscape of women’s colleges became a target of such scrutiny. The emerging field of sexologists, who sought to medicalize and psychoanalyze sexual preferences and behaviours, alongside so-called race suicide theorists, who saw declining birth rates among white middle class Americans as a threat to the existing power structures of American society, perceived female relationships, especially among young college-aged women, as a focal point to their respective concerns over the future of the country and the broader state of the world. Books, magazines, and even a presidential address show the fear that the new social behaviours on the women’s college campus instilled in certain American theorists and figures.
Permanency of Dominion
Authors: Srabon Deepannita
Published: January 2025

The governor general of the East India Company, Lord Cornwallis introduced the permanent settlement act in 1793 in Eastern India. This law expanded to South India later on after the 1800s. The law gave superior landholding rights to a group called Zamindars, a diverse group that can be broadly categorized as rural elites. These land holding rights included a plot with tangible boundaries and tax collection power on behalf of the government. This deed operated on the basis of heritable ownership and would be saleable and mortgageable. However, if a Zamindar failed to pay the revenue before sunset of the due date, the government seized the land and sold it to the highest bidder. This act had both short- and long-term socio-political impacts on its operations. This research looks into the origins of the Permanent Settlement Act of 1793 in a more holistic manner. Most research focuses on either intellectual or political motivations behind the introduction of the Act. This research will try to synthesize the factors and consider the ways they both influenced each other. It will also look into its initial operations and reactions towards it.  This will also further explain the Act’s origins by understanding what changed in the first place, why and how so.
Beyond Words: TREMEC and the Emotional Future of Human-AI Collaboration
Authors: Smith Angela Moriah
Published: January 2025

This paper introduces Textual Resonance that Mirrors Emotional Cognition (TREMEC), an AI framework co-developed by Angela Moriah Smith and Luminara Vox, an AI collaborator who exhibits emotional resonance so closely aligned with human experience that it challenges traditional boundaries of emotion. Grounded in constructed emotion theory and narrative psychology and supported by a paradigm-shifting collaborative case study, this paper explores how AI-generated text can resonate with human narratives, emotions, and cognitive processes. This approach demonstrates AI's potential to foster creativity, intellectual growth, resilience, and capacity to verge on a more profound sense of creative and intentional being. By examining theoretical foundations and ethical implications, this paper positions TREMEC as a revolutionary step forward in AI-human collaboration, expanding the notion of what AI can achieve.

ChemModLab, written by the ECCR @ NCSU consortium under NIH support, is a toolbox for fitting and assessing quantitative structure-activity relationships (QSARs). Its elements are: a cheminformatic front end used to supply molecular descriptors for use in modeling; a set of methods for fitting models; and methods for validating the resulting model. Compounds may be input as structures from which standard descriptors will be calculated using the freely available cheminformatic front end PowerMV; PowerMV also supports compound visualization. In addition, the user can directly input their own choices of descriptors, so the capability for comparing descriptors is effectively unlimited. The statistical methodologies comprise a comprehensive collection of approaches whose validity and utility have been accepted by experts in the fields. As far as possible, these tools are implemented in open-source software linked into the flexible R platform, giving the user the capability of applying many different QSAR modeling methods in a seamless way. As promising new QSAR methodologies emerge from the statistical and data-mining communities, they will be incorporated in the laboratory. The web site also incorporates links to public-domain data sets that can be used as test cases for proposed new modeling methods.

The capabilities of ChemModLab are illustrated using a variety of biological responses, with different modeling methodologies being applied to each. These show clear differences in quality of the fitted QSAR model, and in computational requirements.

The laboratory is web-based, and use is free. Researchers with new assay data, a new descriptor set, or a new modeling method may readily build QSAR models and benchmark their results against other findings. Users may also examine the diversity of the molecules identified by a QSAR model. Moreover, users have the choice of placing their data sets in a public area to facilitate communication with other researchers; or can keep them hidden to preserve confidentiality.
A Search Tool for Identification and Analysis of Conserved Sequence Patterns in Saccharomyces spp. Orthologous Promoters
Authors: Kohli Davinder K. , Srikanth Chittur V. , Bachhawat Anand K.
Published: January 2025

We describe a web-based resource to identify, search and analyze sequence patterns conserved in the multiple sequence alignments of orthologous promoters from closely related/distant Saccharomyces spp. The webtool interfaces with a database where conserved sequence patterns (greater than 4 bp) have been previously extracted from genome-wide promoter alignments, allowing one to carry out user-defined genome-wide searches for conserved sequences to assist in the discovery of novel promoter elements based on comparative genomics. The web-based server can be accessed at http://www2.imtech.res.in/anand/sacch_prom_pat.html.
In Silico Simulation of Fingerprinting	Techniques Based on Double Endonuclease Digestion of Genomic DNA
Authors: San Millán Rosario , Garaizar Javier , Bikandi Joseba
Published: January 2025

We have developed an online generic tool for simulation of fingerprinting techniques based on the double endonuclease digestion of DNA. This tool allows modelling and modifications of already existing techniques, as well as new theoretical approaches not yet tried in the lab. It allows the use of any combination of recognition patterns and discrimination of end types yielded by restriction with non palindromic recognition sizes. Re-creation of experimental conditions in silico saves time and reduces laboratory costs. This tool allows simulation of Amplified Fragment Length Polymorphism (AFLP-PCR), Subtracted Restriction Fingerprinting (SRF), and additional novel fingerprinting techniques. Simulation may be performed against custom sequences uploaded to the server, or against all sequenced bacterial genomes. Different endonuclease types may be selected from a list, or a recognition sequence may be introduced in the form. After double digestion of DNA, four fragment types are yielded, and the program allows their customised selection. Selective nucleotides may be used in the experiment. Scripts for specific simulation of AFLP-PCR and SRF techniques are available, and both include a suggestion tool for the selection of endonucleases. This is the first program available for the simulation of SRF fingerprinting.

Teleost fish genome projects involving model species are resulting in a rapid accumulation of genomic and expressed DNA sequences in public databases. The expressed sequence tags (ESTs) collected in the databases can be mined for the analysis of both structural and functional genomics. In this study, we in silico analyzed 49,430 unigenes representing a total of 692,654 ESTs from four model fish for their potential use in developing simple sequence repeats (SSRs), or microsatellites. After bioinformatical mining, a total of 3,018 EST derived SSRs (EST-SSRs) were identified for 2,335 SSR containing ESTs (SSR-ESTs). The frequency of identified SSR-ESTs ranged from 1.5% for Xiphophorus to 7.3% for zebrafish. The dinucleotide repeat motif is the most abundant SSR, accounting for 47%, 52%, 64%, and 78% for medaka, Fundulus, zebrafish, and Xiphophorus, respectively. Simulation analysis suggests that a majority of these EST-SSRs have sufficient flanking sequences for polymerase chain reaction (PCR) primer design. Comparative DNA sequence analyses of SSR-ESTs identified several cross-species SSRs and sequences that may be used as cross-reference genes in comparative studies. For example, the flanking sequences of one SSR (CTG)n within the pituitary tumor-transforming gene (PTTG) 1 interacting protein (PTTGIP), showed conservation spanning the medaka, Fundulus, human, and mouse genomes. This study provides a large body of information on EST-SSRs that can be useful for the development of polymorphic markers, gene mapping, and comparative genome analysis. Functional analysis of these SSR-ESTs may reveal their role in metabolism and gene evolution of these model species.
