Project Owner Satisfaction Forecasting through Longitudinal Monitoring of Project Team Attributes
Authors: Elnaz Asadian  , Robert Leicht  , Renee Cheng  , Claudia Neuhauser
Published: February 2025

Applying project team success to forecast a building project’s outcomes is challenging due to the presence of a large number of variables in building’s owner goals, program types, and project team composition. However, studying the dynamic interactions of team integration with the project outcomes, which can be represented by owner satisfaction, provides evidence of a meaningful relationship between the success of a project with regard to budget, quality, and schedule. Herein, the association of team integration and group cohesion with the success of project outcomes in terms of owner satisfaction is studied. This purpose was accomplished through regularly gathered information from project teams throughout the project design and construction, followed by the one-time after-completion survey of building owners to understand how and why snapshots of team interactions or dynamics lead to satisfaction perceived by owners. For the seven completed projects with different integration levels, building outcome was measured by owner satisfaction as a proxy for project success. The findings reveal that better team integration can lead to higher owner satisfaction, suggesting teams that are regularly rated high on factors related to strong team culture, such as, “clarity of role” and, “project manager leadership,” are also likely to be rated higher by owners for successful building outcomes. Additionally, projects with more consistent responses across survey categories are more likely to be rated highly by owners. This finding creates an opportunity for planning and managing teams. For those project teams who have been consistent and rated higher in their survey responses, we can expect higher levels of team integration, group cohesion, and, ultimately, owner satisfaction with the overall building results. Consequently, this study offers the potential for in-progress team dynamics measures to help forecast owners' perceptions of their project outcomes.
SOCIAL NETWORK ANALYSIS IN RESEARCH ON DIGITALIZATION IN SUSTAINABLE BUILT ENVIRONMENT: A REVIEW OF RESEARCH CCOMPLISHMENTS AND FUTURE RESEARCH CHALLENGES.
Authors: Kent Eriksson  , Olli Vigren  , Angelika Lindstrand
Published: February 2025

This paper presents a research agenda for Social Network Analysis (SNA) in Digitalization in Sustainable Built Environment research (DSBE). The paper contains a description of SNA, and reviews the use of SNA in DSBE research. Also, the paper identifies future research challenges that SNA can help resolve. A literature review of DSBE finds that of 506 articles in 36 journals, only 1 article includes SNA. This is surprising, given the growing interest in SNA in digitally related fields. We review the 506 DSBE articles and analyze how SNA can contribute to the field. To understand how SNA can be used in DSBE research, we also analyze how SNA has been applied in Digitalization in Built Environment research that is not focused on sustainability. Findings are that SNA can be a useful and powerful tool, because it can help in analysis of how multiple actors interact, which is a common theme in built environment research. An example is that architects, contractors, and developers are separate actor groups that can improve sustainable solutions through networked cooperation. Another area in which SNA can advance research is in the study of how actor networks of companies or people relate to networks of data or physical buildings or sensors. An example is that actors may change their behavior based on sensor data, and SNA can study sensor data networks and actor behavior networks as interconnected layers. Methodological advances are key to advancing research to meet sustainability challenges. Specifically, SNA can make it possible for the built environment area to advance sustainability and digitalization research, because SNA has a rich array of empirical and conceptual tools for the study of networks.
FORUM ARTICLE: REFLECTIONS ON MODELLING APPLICATIONS AND ‘BLACK BOXES’ IN CONSTRUCTION MANAGEMENT RESEARCH - AN OPINION PIECE.
Authors: Dr Sittimont Kanjanabootra
Published: February 2025

Black Box models are a common method of investigations across many knowledge domains including Construction Management. Grounded in Systems Theory the ‘black box is an indeterminate part of a process of identified inputs creating a set of outputs without necessarily understanding the process of inputs getting to outputs. Some researchers argue that it is better to understand what is going on inside the black box, others are less concerned. However, research is showing that investigating what is inside the black box can incrementally enable better understanding of process, albeit that such understanding is somewhat limited. This paper reviews a recent model developed by the author researching the capabilities needed in construction firms to take climate action in their projects. The analysis of that proposed model highlights the understandable set of limitations of the 3 ‘black boxes’ within the model and offers a rationale to investigate what is ‘inside’ those boxes, accepting the difficulties arising. These limitations to knowledge are discussed and their effect as barriers to more complete understanding is investigated. As researchers we constantly need to question what we do and how effective it is.

В работе поводится оценка последствий схода снежных лавин для растительности в лавиносборах, а также результаты исследований воздействия растительности на высоту снежного покрова и параметры снежной толщи. Выявлено, что густой хвойный лес сокращает снегозапас на 40-50 %, а лиственный или лиственничный способствует его максимальному накоплению. Скорость перекристаллизации в лавиносборах, покрытых густым темнохвойным лесов, выше в 5 раз, чем в незалесённых лавиносборах, покрытых курильским бамбуком, а скорость перекристаллизации в лавиносборах, покрытых травянистой растительностью, незначительно выше, чем в лавиносборах, покрытых курильским бамбуком Отмечено, что древесная и кустарниковая растительность в пригребневой части морских террас предотвращает формирование снежных карнизов. Полученные данные исследований могут быть использованы при разработке противолавинных сооружений на о. Сахалин.

The paper evaluates the consequences of avalanches for vegetation in avalanche-hosted areas, as well as the results of studies of the impact of vegetation on the snow cover height and snow column parameters. It was revealed that dense coniferous forest reduces snow accumulation by 40-50%, while deciduous or larch forest promotes its maximum accumulation. The recrystallization rate in avalanche pits covered with dense dark coniferous forest is 5 times higher than in unforested avalanche pits covered with Kuril bamboo, and the recrystallization rate in avalanche pits covered with herbaceous vegetation is slightly higher than in avalanche pits covered with Kuril bamboo. It was noted that tree and shrub vegetation in the ridgeline part of marine terraces prevents the formation of snow cornices. The obtained research data can be used in the development of avalanche control structures on Sakhalin Island.

Ультразвуковые приборы отличает возможность получения данных высокой точности и надежности о свойствах и структуре материалов. Однако существующая аппаратура с применением только продольных волн не совсем пригодна для изучения параметров анизотропных материалов. Использование сдвиговых (поперечных) волн открывает новые перспективы при исследовании этих материалов. На основе акустополяризационного метода разработан аппаратный комплекс АКУСТПОЛ, который позволяет определить число и направленность элементов упругости как высоко, так и низко симметричных образцов анизотропных материалов, оценить степень их неоднородности.

Ultrasonic devices are distinguished by the ability to obtain highly accurate and reliable data on the properties and structure of materials. However, existing equipment using only longitudinal waves is not entirely suitable for studying the parameters of anisotropic materials. The use of shear (transverse) waves opens up new perspectives in the study of these materials. Based on the acoustopolarization method, the AKUSTPOL hardware complex has been developed, which makes it possible to determine the number and direction of elastic elements of both highly and low symmetrical samples of anisotropic materials and to assess the degree of their heterogeneity.

Simplified carbonylation catalyst based on [Co2(CO)8] and coordinating solvents for the carbonylation of β-lactones and α,β-unsaturated acids to cyclic anhydrides
Authors: Pietraru Marie-Hélène , Homassel Antonin , Nicolas Emmanuel , Cantat Thibault
Published: February 2025

Cyclic anhydrides are valuable chemical intermediates and monomers that can be synthesized through the carbonylation of oxygenated substrates like β-lactones and unsaturated acids. Sophisticated cobalt-based catalysts, which require the addition of ligands or presynthesis of a metal cation, have been extensively used to promote such reactions. Herein, we show that the commercial complex [Co2(CO)8] is a suitable catalytic precursor for the carbonylative ring expansion of β-lactones in a wide range of conditions and even at low CO pressure. In particular, succinic anhydride is formed quantitatively from β-propiolactone in the presence of only [Co2(CO)8] in acetonitrile under a moderate CO pressure. The carbonylation of acrylic acid in these conditions is also possible, and provides quantitative yields of product when the gas phase includes H2. This work reinvestigates the potential of [Co2(CO)8] as a catalyst precursor: its disproportionation in the presence of a coordinating solvent (including MeCN and acetone) yields active catalytic species and thus paves the way toward the design of simpler catalytic systems for carbonylation reactions.
Size-exclusion chromatography–electrospray-ionization mass spectrometry to characterize end group and chemical distribution of poly(lactide-co-glycolide) co-polymers

Published: February 2025

The characterization of the microstructure of in vivo degradable polyesters is gaining increased interest thanks to their high-performance applications, such as drug delivery systems. The design of such material requires a high level of understanding of the critical material attributes of the polyesters, such as molecular-weight distribution (MWD), chemical-composition distribution (CCD), and end-groups (functionality-type distribution, FTD). Size-exclusion chromatography (SEC) hyphenated with mass spectrometry (MS) yields SEC-MS, which is an effective method for analyzing the microstructure of polymers. While the MWD can be determined by size-exclusion chromatography hyphenated with ultraviolet spectrometry and refractive index (SEC-UV/RI), the CCD and FTD can be determined by SEC-MS. However, previous applications of SEC-MS have failed to address the risk of polymer fragmentation during the analysis process. It is crucial to establish whether SEC-MS methods can be applied to biodegradable polymers and to recognize if fragmentation processes occurred during the SEC separation or during the ESI-MS process. In this study, we investigate whether SEC-MS methods can be applied to PLGA biodegradable polyesters. The research demonstrates that the choice of alkali metal salt used during ionization strongly influences the stability of PLGA during SEC-MS analysis. CsI was found to minimize fragmentations during ESI-MS, simplifying the MS spectra and allowing isomeric PLGA structures to be distinguished. The resulting method facilitates end-group and CCD determination. Additionally, when combined with selective degradation, the described method can provide insights in the “blockiness” of the polymer and support the development of sequence-controlled PLGA synthesis.
Theoretical Analysis of Racemization Kinetics of the Helical Foldamer: Extended Chain Inhibits Propagation of Helical Reversal from One End to Another
Authors: Suzuki Nozomu , Suzuki Toyoko , Minami Hideto
Published: February 2025

The helical foldamer has been paid increasing attention due to its unique chiral structure and functions. However, little is known about their kinetical stability. To clarify the dynamics of the racemization, we derived the general and approximated equations analytically, assuming that the helical reversal is generated at one end of the helical sequence and travels to another. The general solution was in the form of double exponential while the approximated solution was in a single exponential form. The approximated solution clarified that the kinetic constant is in inverse proportion to the number of helical units (n). Analysis of the previously reported helical foldamers (o-phenylene oligomers and aromatic oligoamide) revealed that the two ends of the helical units are capped by the loose-end domains. The theory suggests the larger n stabilizes the helical structure because the fraction of the helical domain relative to the loose domain increases, and the multiple inversion barrier in the helical domain prevents the helical reversal from traveling from one end to the other.

Published: February 2025

Towards the synthesis and evaluation of stable radical-based 2D frameworks, a diacetylene-bridged tri(9-anthryl)methyl (TAntM) radical dimer was designed and synthesized. X-ray crystallographic analysis revealed a strong spin-spin interaction between TAntM radical units through the diacetylene linker, resulting in a closed-shell [5]cumulene structure as the stable form. Variable-temperature (VT) 1H-NMR measurements at high temperatures showed signal broadening for aromatic protons, indicating an increased population of thermally excited triplet species as a metastable form. To facilitate spin-state modulation by external stimuli, mechanical grinding in the solid state was conducted. Due to its reactivity, mechanical grinding partially induced structural changes to radical species in the solid state.
Kinetic analysis of Group 4 Metal Oxide Nanocrystal synthesis in the presence of phosphine oxide ligands

Published: February 2025

Kinetic control is a powerful tool for traversing the chemical landscape towards the intended product. For group 4 metal oxide nanocrystals, the development of complex multimetallic heterostructures is still a challenge, partly due to the lack of kinetic and mechanistic understanding. Here, we study the reaction kinetics of the nonaqueous synthesis of titanium, zirconium, and hafnium oxide nanocrystals, from the decomposition of metal isopropoxide and metal halide, in the presence of tri-n-octylphosphine oxide (TOPO). The reaction rate depends on the metal: Ti >> Zr > Hf. While titanium follows an SN1 substitution mechanism, zirconium and hafnium follow an auto-catalyzed E1 elimination. In both cases, the reaction kinetics can be tuned by varying the amount of TOPO or the chloride content due to their impact on the electronic structure of the transition state of the rate determining step. The proposed mechanism was shown to be consistent with kinetic modelling of the data for different metal concentrations. This deeper understanding of group 4 metal oxide nanocrystal formation will facilitate access to novel heterostructures, relevant for optical, catalytic, and electronic materials.

Synthetic DNA strand is a highly accessible and biocompatible building block that can be synthesized in virtually any length and sequence, chemically modified, and combined with high specificity via hybridization. Applied within biological environments, in situ hybridization is a powerful biotechnological tool but limited to the use of small numbers of DNA strands. Ex vivo, this principle is the basis of structural DNA nanotechnology, in which hundreds of synthetic DNA strands are designed to self-assemble into highly programmable and versatile platforms, with applications ranging from drug delivery to immunobiology. However, the formation of such structures requires conditions such as temperature and ionic environments that are not only incompatible with living cells but also very long, imposing an ex situ fabrication step before any application with living matter. Here, we report that complex cocktails of DNA strands, coding for so-called DNA origamis, can faithfully self-assemble in situ at 37 °C, in a variety of common cell culture media and directly in the presence of living cells, in just a few minutes. We apply this approach for the in situ assembly of two- and three-dimensional DNA origamis in the presence of human cell lines in 2D culture as well as with 3D assemblies of human induced pluripotent stem cells successfully evolving into cerebral organoids. This life-compatible and highly programmable self-assembly method, requiring only a few minutes of incubation at 37 °C, drastically simplifies the preparation of user-defined complex DNA nanostructures and enables the creation of in situ self-assembling nanomachines for direct and adaptive interactions with living cells.

Harnessing water as a sustainable electron source for artificial photosynthesis remains a significant challenge. This work presents Alice-MOF-1, a novel zirconium metal-organic framework incorporating hexatopic ligands with perchlorinated hexa-peri-hexabenzocoronene (HBC) cores, as a photocatalyst for CO2 reduction using water as the terminal electron donor. Contortion of the ligand, induced by edge chlorination, minimizes π-stacking and enhances solubility, enabling direct MOF synthesis. The controlled arrangement of chromophores within Alice-MOF-1, facilitated by the ligand, is crucial for enabling the complex multi-electron redox reactions. The unique ligand architecture within the MOF promotes symmetry-breaking charge transfer (SBCT), a mechanism observed in natural photosynthesis, leading to efficient charge separation with minimal energy loss. Femtosecond transient absorption spectroscopy and time-resolved electron paramagnetic resonance spectroscopy confirm the formation of long-lived radical ions, providing direct evidence for efficient SBCT and minimal charge recombination. These findings demonstrate the power of MOF-based chromophore assemblies to mimic nature's light-harvesting strategies for sustainable energy conversion.

Supramolecular hacky sacks (SHS) are a novel class of self-assembled colloidal particles formed from guanosine (G) derivatives, designed to function as versatile tools for cellular and therapeutic applications. Here, we investigate the structure-dependent cellular uptake, intracellular trafficking, and functional performance of SHS particles. Confocal microscopy and flow cytometry studies reveal that SHS uptake is highly dependent on the composition of the G-derivatives, suggesting selective interactions with cellular pathways. Importantly, we demonstrate that SHS particles serve as a biocompatible platform for drug and gene delivery, effectively encapsulating and releasing doxorubicin for enhanced cytotoxicity, as well as facilitating plasmid transfection with sustained fluorescent protein expression. These results establish SHS particles as a versatile biocompatible platform with tunable bioactivity, offering new opportunities for the application of supramolecular assemblies in drug delivery and gene therapy. The inherent biodegradability, simplicity of synthesis, and versatility of SHS particles underscore their potential as next-generation biomaterials for biomedical applications.
A Collective Variable for the Control of Solvation in Cage Compounds

Published: February 2025

Host-guest complexation has captivated the curiosity of researchers across disciplines, sparking both experimental and computational studies. Yet, the most common guest, the solvent, is often neglected. In this work we propose a collective variable (CV) to control the occupation of any given supramolecular structure in molecular dynamics simulations. The solvent accessible volume of the cage structures is approximated by a tetrahedral tessellation and is thereby able to adapt in shape and size during the simulation for flexible systems. With a symmetric and smooth function, we can determine a continuous loading by switching the solvent molecules from outside to inside. By applying a harmonic bias, the number of solvent molecules within the cavity can be systematically controlled, and e.g. by umbrella sampling the free energy profile for increased solvent loading can be computed. The approach is applied and validated for a purely organic porous solvent system and a palladium-based metal-organic cage compound. The influence of the smoothing parameter is tested and the results are com- pared to available experimental data as well as prior simulation results. The method is shown to be versatile and efficient in quantifying the loading of flexible and deforming molecular cages while monitoring the subsequent reactions of their hosts, with relevance for catalytic processes or separation using such tunable systems.

Published: February 2025

The increasing interest in efficient organic synthesis by applying solar radiation has propelled a surge in the demand for introducing new types of photocatalysts in synthetic toolboxes. During the last few decades, tremendous efforts have been invested in developing low-cost, non-toxic, stable, and potent photocatalysts. In this perspective, Cesium Lead Halide perovskite (CsPbX3) nanocrystal has emerged as a brand new photocatalyst, creating a renaissance in pioneering organic photochemistry with its enchanting optoelectronic features. Due to their unique band structure, tunable bandgap, and near unity quantum yield, these highly fluorescent nanocrystals are exceptional candidates to catalyze numerous fundamental organic transformations by absorbing energy from ultraviolet to visible regions. Also, anion metathesis, long average excited state lifetime, tunable morphology, and photo-generated charge carriers, make them capable of a broader range of organic substrate activation in bench-stable conditions. These nanocrystals are well known for their superb power conversion efficiency (PCE) of solar radiation which reached up to 26.3% in the last few years, and its potential has already surpassed everyone’s expectations in multiple fields like photovoltaics, photoelectronics, lasers, scintillators, etc. But, its use in photo organic chemistry just started and we believe this typical promising material is going to fetch a new era in the field of organic photocatalysis. This comprehensive review systematically summarizes the development made over CsPbX3 perovskite catalysis in the last few years by assembling pieces of literature on perovskite-based organic reactions. And also, explores the intricacies of the underlying mechanistic cycles and discusses limitations with future scope of exploration

Published: February 2025

This study examines the influence of gender on the use of English by Kurdish as non-native English speakers in online Interlocutors. It aims at figuring out the contributive role of language to the identification of the interlocutors’ gender, determining the influence of cultural norms on shaping the online communication patterns of Kurdish interlocutors(males and females), and identifying the frequency use of the essential linguistic elements, strategies and styles that distinguishes males’ interactions from females’. This study employs a mixed method, quantitative and qualitative, in the process of data analysis. It is quantitative for administrating a Likert-Scale questionnaire to investigate the perceptions of Kurdish as non-native English speakers according to gender and its influence on the interactions conducted online. It is also qualitative for analyzing one hundred instant messages extracted from males and females’ interactions held in three Telegram public channels. The most two significant concluding points that this study has come up with are: (1) gender diversity affects all the aspects of language including word choice, strategy and style in online interactions, and (2) the frequency of using hedge devices, empty adjectives, euphemistic expressions, apologies, justifications, minimal responses, emoticons, tag-questions, rhetorical questions, intensifiers and exclamatory expressions used by females is far more compared to males. However, males use humor and sarcastic expressions far more compared to females.

La obra psicoanalítica de Sigmund Freud no ha perdido vigencia. Ya sea que se le utilice como un método terapéutico; como una vía para pensar al ser humano en su dimensión psíquica, consciente e inconsciente, e interpretar sus acciones; o como una manera de explicar la cultura y los comportamientos colectivos, los textos freudianos siguen constituyendo un referente explicativo de variados fenómenos intrapsíquicos y psicosociales. En este sentido, constituye una institución que debe seguir explotándose.

Published: February 2025

Blockchain is the foundation of cryptocurrencies, and most cryptocurrency technologies are decentralized. This study explains the topic of scalability in blockchains and presents a comparative analysis of numerous blockchain metrics with real-time data. This study performed this using a blockchain simulation (BlockSim) and then looked at effective techniques that may be utilized to overcome the limitation by comparing the simulator and real-world circumstances. This paper proposes an effective algorithm that improves the scalability of the Bitcoin network through efficient transaction deferment. This study also proposes an algorithm that improves the current Bitcoin protocols using inventory messaging (INV) and transaction deferment or adjournment. These improvements are compatible with the existing Bitcoin Network protocols. The improved algorithm was simulated using BlockSim and the AnyLogic Multi Paradigm Simulation Engine. The simulators were configured with 1000 nodes interconnected in a Bitcoin-like peer-to-peer network. The result of the simulation shows that the adjourned transaction protocol provides for a controlled reduction in the number of messages required to propagate a transaction at the cost of a modest increase in transaction propagation time. This system can manage the tradeoff between the quantity of messages and propagation latency by adjusting the threshold and timeout values, thereby improving the network's overall scalability.

Published: February 2025

The paper proposes a novel approach that integrates machine learning and NLP in order to identify phishing sites and create multilingual interaction by providing better user engagement through the chatbot. It will utilize the XG-Boost algorithm in order to show the phishing detection system with more than 90% accuracy rate in the identification and classification of websites as legitimate or phishing for a set of 10,000 websites. A major contribution of this work is the embedding of a multilingual chatbot, developed on Dialog- flow, with support for English, Hindi, and Marathi, thereby broadening the possible community of users for the system. This paper describes the architecture of the system at its different layers- feature extraction, model training, and its integration with the chatbot. The proposed work fills the gaps in earlier literature as it provides a user interface accompanied by robust detection. This system will also be extended by the provision of language support by adding more languages in the near future and also by increasing the detection accuracy using deep learning models. The results demonstrate that combining machine learning with user-centric design may improve the detection of phishing sites considerably and enhance user engagement.

The objective of this study was to evaluate the effectiveness of constraint-induced movement therapy on motor function among stroke patients in selected hospitals in Erode, Tamil Nadu, India. A quasi-experimental design with a pre-test and post-test control group was used. The study was based on a modified version of Wiedenbach's Helping Art of Clinical Nursing Theory. A purposive sampling technique selected 60 participants, 30 in the experimental group and 30 in the control group. A pre-test was conducted using the Fugl-Meyer Assessment Scale. In the experimental group, the researcher demonstrated and assisted participants with range-of-motion exercises for 30 minutes, and activities of daily living were performed. Data were analyzed using descriptive and inferential statistics. Regarding motor function, the mean post-test score in the experimental group was 77.13 (SD ± 9.85), compared to 45.3 (SD ± 8.53) in the control group. The independent t-value was 12.83, significant at p < 0.05. No significant association was found between posttest scores and demographic variables, except for family monthly income (χ2 = 12.59, p < 0.05). The findings revealed a significant improvement in motor function following constraint-induced movement therapy, enhancing motor function and promoting stroke patients' well-being.

Pain management is a critical aspect of nursing care, directly influencing patient outcomes and quality of life. This paper explores the nursing perspective on pain management, emphasizing holistic and patient-centered approaches that are essential for effective pain relief. Nurses play a pivotal role in pain assessment, utilizing various tools and techniques to evaluate pain intensity, location, and its impact on daily activities. The integration of pharmacological and non-pharmacological interventions is crucial in developing comprehensive pain management plans. Pharmacological approaches include the administration of analgesics, opioids, and adjuvant therapies, tailored to individual patient needs and clinical conditions. Non-pharmacological strategies, such as cognitive-behavioral therapy, relaxation techniques, and physical modalities, are also highlighted for their significant contributions to pain relief. This paper underscores the importance of continuous education and training for nurses to stay updated on evolving pain management practices and to ensure the safe and effective use of pain relief modalities. Additionally, it addresses the challenges nurses face, such as balancing the risks of opioid use, managing patient expectations, and overcoming barriers to accurate assessment in diverse populations. By adopting a collaborative approach that includes patients, families, and multidisciplinary teams, nurses can enhance the effectiveness of pain management and contribute to improved patient outcomes. Future research directions are suggested to address gaps in knowledge and practice, ensuring that pain management strategies continue to evolve and improve.

Pregnancy is a sensitive period in a woman's life. During this time, pregnant mothers experience stress due to various factors, such as physiological, psychological, and social adaptations. This can lead to high levels of stress, especially among high-risk mothers. Guided imagery is an effective relaxation technique that can reduce stress, providing relaxation to both the mind and body. It alleviates stress and mitigates negative pregnancy outcomes. The aim of this study is to assess the effectiveness of guided imagery on stress among high-risk pregnant mothers in selected hospitals in Kanyakumari District, Tamil Nadu, India. A quantitative approach with a quasi-experimental pretest-posttest control group design was adopted. Sixty high-risk pregnant mothers, 30 in the experimental group and 30 in the control group, were selected using a non-probability purposive sampling technique. The Perceived Prenatal Maternal Stress Scale was used to assess the stress levels of high-risk mothers. In the experimental group, the pretest mean stress score was 31.63± 8.65, and the posttest mean stress score was 13.16 ± 1.23. The mean difference was 18.46, and the 't' value was 11.94, which was statistically significant at the 0.05 level. The study revealed that guided imagery was effective in reducing stress among high-risk pregnant mothers.

2,4-Диамино-3,5,6-трифторбензонитрил образует с макроциклическими эфирами 18-краун-6, 15-краун-5 и 12-краун-4 сокристаллы стехиометрии 4:3, 1:1 и 2:1, соответственно. Неспособность к 1:1 сокристаллизации с 18-краун-6 и немонотонное изменение доли диамина в сокристалле при изменении размера макроцикла выделяют его из ряда структурно близких полифторарилендиаминов. Во всех синтезированных сокристаллах цианогруппа и полифторароматический фрагмент участвуют в структурообразующих взаимодействиях (Н-связь N‑H···Ncyano, π⋯π и p⋯π контакты), дополняющих H-связь с краун-эфиром N-H···Ocr. Квантово-химические DFT расчеты молекулярного электростатического потенциала, энергий связывания и топологических параметров электронной плотности в димерах показывают значительный вклад взаимодействий между молекулами ароматического коформера в стабилизацию структуры сокристаллов. Ключевым фактором, обеспечивающим сокристаллизацию в соотношении 1:1, является π-стекинг, который реализуется в сокристалле с 15-краун-5 и нарушается при переходе к 18-краун-6 из-за увеличения размера макроцикла. Проведенный структурный и квантово-химический анализ характеризует иерархию супрамолекулярных синтонов как инструментов дизайна молекулярных кристаллов.
