Interplay of interactions in nanoparticle–surfactant complexes in aqueous salt solution

The evolution of phase behavior and interactions in anionic silica nanoparticles (Ludox HS40), surfactants [non-ionic decaethylene glycol mono-dodecyl ether (C12E10) and anionic sodium dodecyl sulfate (SDS)], and nanoparticle–surfactant solutions in the presence of salt (NaCl) has been studied using small-angle neutron scattering and dynamic light scattering. In an anionic silica nanoparticle solution (1 wt. %), the phase behavior is controlled by salt concentrations (0–1 M) through screening electrostatic interactions. In the case of 1 wt. % surfactant solutions, the anionic SDS surfactant micelles show significant growth upon adding salt, whereas non-ionic surfactant C12E10 micelles remain spherical until a high salt concentration (1 M). In the mixed system of HS40–C12E10, a transition from a highly stable transparent phase to a two-phase turbid system is observed with a small amount of salt addition CS* (∼0.06 M). The single transparent phase of this system corresponds to sterically stabilized micelles-decorated nanoparticles. For the turbid phase, the results are understood in terms of depletion attraction induced by non-adsorption of C12E10 micelles, which explains the appearance of turbidity at a much lower concentration of salt. In the mixed system of similarly charged nanoparticles and micelles (HS40-SDS), the phase behavior is governed by no physical interaction between the components, and salt screens the repulsive interaction among nanoparticles. These results are further utilized to tune multicomponent interactions and phase behavior of nanoparticles with a mixed C12E10-SDS surfactant system in the presence of salt. The mixed surfactants provide tuning of nanoparticle–micelle as well as micelle–micelle interactions to dictate the phase behavior of a nanoparticle–surfactant solution. In these systems, the effective potential can be described by double-Yukawa potential taking account of attractive and repulsive parts at low and intermediate salt concentrations (<CS*). At high salt concentrations (>CS*), the aggregation of nanoparticles is characterized by fractal aggregates.

Densities and isothermal compressibilities from perturbed hard-dimer-chain equation of state: application to nanofluids

Abstract Densities and isothermal compressibilities of several nanofluids were modelled using a perturbed hard-chain equation of state (EoS) by an attractive term from Yukawa tail in 273–363 K range and pressure up to 45 MPa. The nanofluids of interest comprise TiO2-Anatase (-A), TiO2-Rutile (-R), SnO2, Co3O4, CuO, ZnO, and Al2O3 as nanoparticles dispersed in ethylene glycol, water, poly ethylene glycol, ethylene glycol + water, and poly ethylene glycol + water as base fluids. The EoS was capable of estimating 1397 density data of 9 nanofluids with the overall average absolute deviations (AAD) of 0.90%. The coefficients of isothermal compressibility of 6 selected nanofluids were also predicted using the EoS with the AAD of 5.74% for 1095 data points examined. The PHDC EoS was not capable of estimating the excess volumes of 3 selected EG-, PEG-, and water-based nanofluids accurately as the relative deviations from the literature data were greater than 34%, even though the trend of results against the nanoparticle concentration was in accord with the literature. To further investigate the density prediction, we have trained a neural network with a single hidden layer and 17 neurons which was able to predict the densities of nanofluids accurately.

AN ANALYTICAL PERSPECTIVE OF RESIDENTS’ VIEW ON THE PROVISION OF RECREATIONAL FACILITIES USING WARP-PLS

Recreational facilities are among the vital services that aid in the development of a community, but its provision is complex. Hence, the need for the involvement of residents in the provision processes. This paper aims to examine the residents’ view of the provision of recreational facilities in the Greater Jos metropolis of Nigeria. The data were collected from the field survey and analysed empirically. The partial least squares structural equation modelling technique was applied in analysing the responses. The results show that the provision has a significant positive effect on the relationship between appropriateness and stakeholders' involvement. In contrast, the provision had a significant negative effect on the relationship between accessibility indicators. Accessibility does not affect the relationship with the provision of recreational facilities. In conclusion, it has been determined that the relationship between the provision is stronger with the appropriateness in terms of categories and attractiveness of the facilities.

Intercrops as foraging habitats for bees: Bees do not prefer sole legume crops over legume-cereal mixtures

Enhancing crop diversity is an option to make agriculture more sustainable and biodiversity friendly. Intercropping grain legumes together with cereals leads to higher crop diversity and has a broad range of agronomic and ecological benefits. However, sole crop stands of grain legumes might be richer in floral resources than grain legume-cereal intercrops and thus are probably more useful to mitigate the lack of flower resources in agricultural landscapes, which is a main driver of pollinator decline. Yet, little is known about differences between both cropping systems and different legume genotypes in terms of attractiveness for pollinators and how these differences moderate the pollinators’ foraging behavior and consequences for grain legume yields. In a field trial, we analyzed the abundance of flower visiting insects, the foraging behavior of pollinators and related effects on grain yield per plant across six different faba bean genotypes (Vicia faba L.) grown as sole crops or as intercrops with wheat. As foraging behaviors, we considered legal flower visits (i.e. frontal visits) and illegal flower visits (i.e. nectar robbing through bite holes). We recorded characteristics of V. faba genotypes on crop stand level (V. faba plant height, number of V. faba inflorescences and leaf area index (LAI)). V. faba-wheat intercrops and sole crop stands of V. faba were equally attractive foraging habitats for pollinators, implying that intercrops are as suitable as sole crops to mitigate the lack of floral resources. Yield per V. faba plant was positively affected by bee pollination, with this effect being determined by the number of illegal flower visits, suggesting that this foraging strategy does not adversely affect V. faba yields and even has a positive effect. Intercrops had higher yields per V. faba plant than sole crop stands of V. faba, indicating agronomic advantages of this farming practice. Although V. faba genotypes differed in their plant traits, these differences could not explain shifts in the number of flower visiting insects. However, illegal flower visits increased with a higher number of inflorescences whereas the number of legal flower visits declined. Based on our small-scale experiment, we conclude that the use of V. faba-wheat intercrops brings agronomic benefits while serving as a foraging habitat for pollinators that proved to be as attractive as sole crop stands of V. faba.

Analysis of Trip Attraction Models in Morotai CBD (Central Business District)

The development of an area in land use can increase along with the increase in population in Morotai Island Regency, including the Morotai CBD area. In terms of urban transportation systems, generation and attraction have an important role in defining the development of a city, region, or area. The purpose of this research is to analyze of trip attraction modeling in the CBD area of Morotai. The concept of trip attraction modeling is analyzed using regression analysis, with various independent variables. The modeling analysis was carried out with the help of SPSS software using Stepwise multiple linear analysis methods. The results of the study show that the factors that influence the attraction of vehicle in the Morotai CBD area are : the number of visitors (X4), the ratio of visitors against the building area (X10), the ratio of employees against the number of rooms (X13), the number of rooms(X5), the ratio of employees against the building area (X11), as well as the ratio of employees against the number of rooms(X12). And from the results of linear regression analysis, the best transport attraction model was found to be Y 1 = 86.790 + 0.422X 4 – 558.735X 10 + 1.949X 13  for the motorcycle (SM) attraction model and Y 2 = 12.183 + 0.091X 5 – 26.265X 11 + 0.292X 12 for the light vehicle (KR) model.

Recognizing the diversity of the Portuguese transgender population: A cross-sectional study

The transgender population comprises anyone who wishes to be socially recognized as a distinct gender from their birth-assigned sex, with or without the desire of undergoing gender-affirming treatments. Its complexity is recognized, but remains an understudied topic, particularly in Portugal. The main goal of this study was to recognize and characterize the heterogeneity of this population, by exploring the possible gender identities, sexual orientations, and perspectives on the available treatments for gender dysphoria, including psychotherapy, hormone therapy, and sex-reassignment surgery. We applied an in-person, self-completion survey to 46 transgender individuals followed at the Psychiatry Department of the University Hospital Center of São João. The typical profile of our respondents was a young person, the majority being assigned female at birth, with upper secondary or higher education. Most of the patients were currently undergoing psychotherapy (89.1%) and hormone therapy (60.9%), but only a quarter had breast surgery in the past (26.1%). Satisfaction was lower towards breast surgery, but overall median satisfaction with all procedures was high. This study effectively demonstrates the diversity of the transgender population, pointing out differences in terms of sociodemographic data, gender expression, sexual attraction, treatment adherence and related satisfaction, while also gathering the necessary feedback to improve healthcare.

Differences in Visual Attraction between Historical Garden and Urban Park Walking Scenes

Previous studies on visual perception and landscape element preference have mainly focused on urban green spaces such as parks and forests; the visual attraction potential of historical gardens has been less explored. Based on the analysis framework of the visual landscape experience, this study employed normalized eye-tracking data and preference questionnaires to compare the difference in visual attraction of typical walking scenes between historical gardens and urban parks. The results showed that in terms of landscape elements, the variation fluctuation of the fixation time on various landscape elements by participants viewing historical garden walking scenes (HGWSs) was less than for urban park walking scenes (UPWSs). Additionally, the visual perception scores of the former (i.e., fascinating, coherent, complex, and mysterious) were higher than the latter. In terms of the visual attention area, the visual exploration of HGWSs around the scene (i.e., top, bottom, left, and right) was longer than for UPWSs, while the latter’s central fixation time was longer than that of the former. The visual attraction of HGWSs was related to the foreground and middle ground, while that of UPWSs was related to the middle ground and background. Additionally, for policy makers and managers of urban green spaces, the recommendation of the present study was to consider and evaluate the differences between HGWSs and UPWSs in terms of visual attraction before policy establishment.

Perceptions of candidate strength in job recruitment: Does candidate race moderate the attractiveness bias in White women?

AbstractThe attractiveness bias suggests that people who are more attractive will be positively favored across life outcomes. This study sought to test whether candidate attractiveness, sex, and race, affect perceptions of candidate strength in a job recruitment task. In total, 338 White women (Mage = 20.94 ± 5.65) were asked to make judgements of a potential candidate for an administrative job (resume with candidate photograph). The vignettes differed in terms of candidate ability (strong/weak), sex (male/female), race (Black/White), and attractiveness (attractive/less attractive). Participants rated perceived candidate strength and likelihood to invite for interview. Results showed no significant main effects for attractiveness. However, there was a significant interaction for target attractiveness and race, such that attractive/White candidates were more likely to be invited for interview than less attractive/White candidates. There was also a significant main effect for race such that Black candidates were rated as stronger and more likely to be interviewed. Sensitivity analyses (with nonheterosexual women removed from the sample) also showed a main effect for target sex such that female candidates were favored over male candidates. Overall, these findings provide evidence that attractiveness, sex, and race have important, albeit complex, effects on hiring decisions in the workplace.

The Schelling-Eschenmayer Controversy, 1801: Nature and Identity by Benjamin Berger and Daniel Whistler

Reviewed by: The Schelling-Eschenmayer Controversy, 1801: Nature and Identity by Benjamin Berger and Daniel Whistler Mark J. Thomas Benjamin Berger and Daniel Whistler. The Schelling-Eschenmayer Controversy, 1801: Nature and Identity. Edinburgh: Edinburgh University Press, 2020. Pp. xvi + 269. Hardback, £80.00. This excellent book focuses on a decisive moment in Schelling's philosophical development: his 1801 dispute with Eschenmayer shortly before publishing Presentation of My System, the inaugural text of his identity philosophy. Carl August Eschenmayer was a German physician whose Kant-inspired writings in the philosophy of nature greatly influenced Schelling, especially with respect to the doctrine of the potencies. Nonetheless, he is a marginal figure in the history of philosophy, and one might assume that this volume will only interest Schelling specialists or those concerned with the minutiae of nineteenth-century Naturphilosophie. That would be a mistake. As Berger and Whistler demonstrate, the 1801 controversy has significant implications for understanding the trajectory of German Idealism and its debates on methodology, the meaning of identity, and the place of nature in philosophy. [End Page 703] Part 1 of this volume contains translations of the two essays at the heart of the dispute, both published in January 1801 (Judith Kahl and Daniel Whistler are the translators). The essay by Eschenmayer, "Spontaneity = World Soul, or The Highest Principle of Philosophy of Nature," critiques Schelling's 1799 nature-philosophy and presents his own Fichte-inspired approach. Schelling's rejoinder is the essay "On the True Concept of Philosophy of Nature and the Correct Way of Solving Its Problems," which anticipates the new identity philosophy he would present later that year. Translations of the two thinkers' correspondence and selections from other works by Eschenmayer are included in appendices. Overall, the translations are precise and quite readable—an achievement for German texts with scientific jargon. Moreover, the translators are thoughtful in their rendering of tricky words like Verhältnis, which can mean "relation," "proportion," or "ratio" in different contexts (see xiii–xiv). Occasionally there are minor inaccuracies, but they do not detract from the texts' main arguments. What, then, are the main points of disagreement between Schelling and Eschenmayer? In the preface, the authors identify a "twofold difference" (ix). The first concerns the relationship of the philosophy of nature to transcendental philosophy. Eschenmayer follows Fichte in including the former within the latter: the "I" is ultimately responsible for nature's determinate features. By contrast, Schelling insists on the self-sufficiency of naturephilosophy and argues for its priority: consciousness and the transcendental standpoint are not original but are derived from nature (9–10). The second difference concerns the source of qualitative difference among natural phenomena. While Eschenmayer reduces quality to mathematical proportions of attraction and repulsion, Schelling argues that such a reduction amounts to explaining nature's diversity through varying degrees of density (56). The bulk of the volume (part 2) is a series of chapters on themes related to the dispute and its aftermath. Though labeled "commentaries," they are really critical essays, providing historical context and analysis while engaging with an impressive range of secondary literature. The first chapter is devoted to the construction of material qualities, the "guiding thread" of Eschenmayer's essay (83). The authors carefully trace the problem from Kant through the two philosophers' evolving conceptions of nature-philosophy leading up to the 1801 dispute. Though Schelling rejects Eschenmayer's account of quality in terms of attraction and repulsion, he is "greatly influenced" by his sparring partner's emphasis on quantitative difference in explaining quality, even adopting some of his mathematical concepts (89). The most important of these is "potency," the subject of the next chapter and one of the central concepts in Schelling's thought for the next forty years. After an account of its roots in mathematics and Eschenmayer's nature-philosophy, the authors analyze core features of potency in the 1801 Presentation, contrasting it with dynamis in Aristotle. Fundamentally, the series of potencies involves differentiation through intensification of the same underlying identity: "Life is nothing more than intensified inorganic matter" (102). The chapter concludes with a strong defense of Schelling against Hegel's charge of formalism—though it still seems to me that the schema of...

Talent Management in the Hospitality Sector: Predicting Discretionary Work Behaviour

Hospitality organisations have suffered a lot of setbacks, such as low performance caused by the COVID-19 pandemic, during which most management took drastic decisions to retrench talent, and these decisions have engendered low discretionary work behaviour and low emotional labour display amongst its talent. These maladies would have been averted if talent management practices were implemented effectively by hospitality organisations. It is based on this premise that this study investigates the effect of talent management on discretionary work behaviour in hospitality organisations in Nigeria using a survey research design. A sample frame of 820 was drawn from 60 registered hospitality organisations in the south-eastern part of Nigeria. A sample size of 263 was drawn from the sample frame. Linear regression was employed to analyse the formulated hypotheses with the aid of IBM statistical package for the social sciences version 20.0. The findings of the study show that talent management dimensions have significant effects on discretionary work behaviour in hospitality organisations in Nigeria. The study concludes that talent management measured in terms of talent attraction, talent development and talent retention have significant effects on the indicators of discretionary work behaviour. The study recommends that human resource professionals and organisational leaders should utilize talent management as a strategy to enhance discretionary work behaviour in their respective organisations.

Pedaling through a virtually redesigned city: Evaluation of traffic planning and urban design factors influencing bicycle traffic

To achieve the 1.5-degree target of the Paris Climate Agreement, it is of great importance to promote environmentally friendly means of transport. In urban areas, shifting motorized trips to active transport modes (i.e., walking and cycling) is essential. Therefore, knowledge of walking and cycling is indispensable for planning and policy, which is the basis for targeted promotion of active forms of mobility. This paper aims to identify factors that specifically influence cycling and to derive recommendations for action for planning and policy in a virtual testbed. Specifically, the influence of traffic planning measures (i.e., structural infrastructure facilities for stationary and moving traffic as well as traffic regulations) and urban design measures (i.e., the design of public space) on the promotion of cycling will be shown. For this purpose, a virtual reality simulation was used, independent of different external conditions during field surveys and the necessity of time-, cost- and regulation-intensive structural changes. Using an improved bicycle simulator, 93 people cycled through 20 variations of an approximately 680 m long road section, surveying the effect of selected traffic planning and urban design parameters. Special attention was paid to the subjective safety of the cyclists and the attractiveness of the urban environment. Furthermore, three types of infrastructure were differentiated: No bicycle infrastructure (riding on the roadway), a bicycle lane, and a structurally separated cycle path next to the sidewalk. The virtual road section represented a real location. In addition to the findings gained from the physiological optimization of the simulator, the results show that roadside greenery had the highest effectiveness in terms of subjective safety and attractiveness. Other factors with a high influence were a speed reduction from 50 to 30 km/h when riding on the roadway with cars and the red coloring of the bicycle lane, each increasing the perception of safety. In contrast, a lack of a boundary line between the cycle path and the sidewalk was unsettling for those who rarely or never ride bicycles in their daily lives. In addition, restaurant and recreation areas increased the attractiveness of the road section, although entailing a lower perception of safety. Other factors, such as motor vehicle traffic volume or vehicles parked at the roadside, showed no significant effects on the evaluation of cycling.With the help of these findings, the consequences of traffic planning and urban design measures can be better assessed in subsequent virtual testbeds. Also, initial trends can be identified as to which planning instruments should be used as a priority to promote cycling in urban areas. Future work should validate the transfer of these insights into physical urban spaces to support further the mid-term transformation towards sustainable urban mobility using scientific evidence.

Architectural studies in the European Higher Education Area: Criteria for student degree mobility

Abstract The European Higher Education Area was implemented as a result of the Bologna Process and set the mobility of students and staff as its main goal, suggesting tools to facilitate it. The European Union has supported the suggested measures, as mobility can be a way to support a common European identity and a strategic way to improve the quality of higher education institutes. Architectural studies, due to their special character as both an art and a science discipline, are chosen as the education area most suited for mapping degree mobility and highlighting the characteristics that differentiate each school in terms of attraction to international students. How do architectural students select the school to continue their studies? On what criteria is that based? There were more than 351 schools of architecture in the European Higher Education Area with 49 participating countries at the time the research was conducted. Do international students choose them at the same degree? What makes a difference between them, causing some of them to become famous schools of excellence while others are barely visible in the international competition? To answer the above questions, a research based on two questionnaires was conducted during the academic year 2018-2019. The aim of both questionnaires was to map the state of the art in architectural studies and determine the criteria students value the most to make their choices at master studies. The process of combining the data collected from both questionnaires showed that the study programmes and the city or country of the school are the main reasons for master’s students to choose a specific school and for schools to stand out. This is followed by the criteria: offered studies’ quality, institution’s reputation, teaching language, the host city’s economy, giving students the possibility to work during and/or after studies, the offer of third cycle. The paper concludes suggesting changes schools could implement if they wish to get a better position in the competitive market of attracting international students.

P26 - My Mater Midwife: A Collaborative Private MGP Model

With the aim of increasing access to high quality continuity midwifery, Mater South Brisbane recently launched an innovative new model of collaborative private care called My Mater Midwife. Within this model, private clients of participating obstetricians have their care shared collaboratively between their chosen obstetrician and an endorsed midwife employed by the hospital. The primary midwife is on call for hospital presentations and eventually the birth, supported by a small midwifery team. Clients have their known midwife and known doctor present for their birth, enjoy the comfort of a private postnatal stay in hospital and receive the ongoing support of their primary midwife delivering homecare after discharge. The model will be explained in more detail including how we meet the needs and expectations of the various stakeholders and the challenges we have faced in establishing the model. This presentation has been developed in collaboration with one of the participating obstetricians, Di Poad whose contribution will be pre-recorded. Continuity midwifery models of care have been well established by research to improve client outcomes over a wide range of measurable factors. As a private hospital, Mater wanted to be able to offer this “gold standard” of care to private clients who were accessing their maternity care through private obstetricians. The model is aimed at people seeking the comfort of private maternity care along with the benefits of continuity midwifery. While challenging at times to establish mutually attractive terms of involvement for all stakeholders, the current model honours the professional contribution of both obstetricians and midwives while centring the birthing person and adapting care around their needs. Feedback from clients birthing in the model has been overwhelmingly positive.

Impact of facial components on the attractiveness of face: A perception-based study

Magazines and television displays are not merely crammed with faces-they are filled with appealing faces, and both men and women are interested in a suitable partner's appearance. This study investigated what makes a face attractive and whether perception-related differences exist between facial attractiveness and facial components. In this descriptive-analytical study, frontal and lateral view photographs of 18 young adults (9 male and 9 female) in Class I, II, and III malocclusions were assessed by 90 orthodontists, dentists, models, and laypeople using a 7-point Likert scale in terms of attractiveness. Based on scores, attractive and unattractive groups were formed. Using image analysis software, a range of defined length, angles, perimeter, and area for lips, nose, and chin were measured for the attractive group. For statistical analysis, each group was compared using a 1-way analysis of variance. Logistic regression was performed to analyze the factors of different parameters to the attractiveness of facial components. Overall full-face width, upper lip angle, lip area, and mentolabial angle was significantly different in all the 3 classes (P≤0.05). In Class I malocclusion, nasolabial angle among orthodontists, nasofrontal angle among dentists, lower lip among models, and full-face width among laypeople were responsible for facial attractiveness variation. In Class II malocclusion, nose to upper lip among orthodontists, Cupid's bow among dentists, wider face among models, and upper lip among layperson were responsible for variation in facial attractiveness. In Class III malocclusion, lower lip angle among orthodontists and dentists, Cupid's bows among models and layperson was responsible for variation in facial attractiveness. In Class I faces, lips (Cupid's bows, lower lips, lip areas), nose (nasolabial, nasofrontal, and nasomental angles), and chin (lower lip to chin) contributed to the overall attractiveness of the face, while in Class II faces, lips (upper lip length, interbow distance, lower lip angle), nose (full facial convexity), and chin (mentolabial sulcus), as well as a greater full-face width contributed to the overall attractiveness of the face. In Class III faces, lips (lower lip angle, upper lip length), nose (nose tip angle, full facial convexity), and chin (mentolabial sulcus depth) contributed to the overall attractiveness of the face.

The Influence of Colorblind and Race-Acknowledged Organizational Socialization Messages During Offer Consideration

This study investigated a key question involved with attracting and retaining a diverse workforce: Should recruiters provide race-related realistic organizational previews (ROPs) to job candidates from historically-marginalized groups during the offer consideration phase? Colorblind (i.e., race ignoring) socialization practices are likely motivated by several fears. Yet, a colorblind strategy may also miss potential advantages afforded by race-acknowledging ROPs. Black and African-American ( N = 338) individuals participated in a three (colorblind, implicit, or explicit ROP-type) × two (Black or White recruiter) message processing experiment. Statistical analyses revealed that implicit race-acknowledged ROP messages were comparable to a colorblind condition in terms of organizational attraction and motivation to join the organization. Furthermore, an implicit race-acknowledged ROP message was associated with higher intention to accept a job offer than an explicit race-acknowledged ROP. Analyses also revealed that participants perceived recruiters as credible and polite, regardless of recruiter’s racial identity or the race-related explicitness of the ROP message. Implications of the study conclude the paper.

Image variability and face matching.

This study investigates whether variability in perceived trait judgements disrupts our ability to match unfamiliar faces. In this preregistered study, 174 participants completed a face matching task where they were asked to indicate whether two ambient face images belonged to the same person or different people (17,748 total data points). Participants completed 51 match trials consisting of images of the same person that differed substantially on one trait (either trustworthiness, dominance or attractiveness) with minimal differences in the alternate traits. Participants also completed 51 mismatch trials which contained two photos of similar-looking individuals. We hypothesised that participants would make more errors on match trials when images differed in terms of attractiveness ratings than when they differed on trustworthiness or dominance. Contrary to expectations, images that differed in terms of attractiveness were matched most accurately, and there was no relationship between the extent of differences in attractiveness ratings and accuracy. There was some evidence that differences in perceived dominance and, to a lesser extent, trustworthiness were associated with lower face matching performance. However, these relationships were not significant when alternate traits were accounted for. The findings of our study suggest that face matching performance is largely robust against variation in trait judgements.

A Systematic Review of Circulating Tumor Cells Clinical Application in Prostate Cancer Diagnosis.

Simple SummaryCell-dependent and cell-independent information drawn from the blood stream were merged into the attractive term “liquid biopsy” and tentatively applied to most segments of cancer management: detection, risk-stratification, personalization of care and follow-up. However, the robust science behind liquid biopsies has not been widely used, thereby remaining a latent and possibly undervalued instrument. Here, we conducted a systematic review of CTCs in prostate cancer management to summarize their use in clinical practice.The purpose of the review is to summarize the recent data on circulating tumor cells (CTC) use in clinical practice. We performed a systematic literature search using two databases (Medline and Scopus) over the past five years and the following terms: (CTC OR “circulating tumor cells” OR “liquid biopsy”) AND prostate. The primary outcome was CTC predictive value for prostate cancer (PC) progression and survival. The secondary outcomes were the CTC predictive value for therapy response and the results of CTC detection depending on the assessment method. In metastatic PC, the CTC count showed itself to be a prognostic marker in terms of clinically important features, namely survival rates and response to treatment. CTC concentration was significantly associated with the overall survival and progression-free survival rates. A strong association between the overall survival or progression-free survival rate and CTC concentration could be observed. Variant-7 androgen receptors-positive (AR-V7-positive) patients showed a poor response to androgen receptor signaling (ARS) inhibitors, but this did not compromise their response to taxanes. In localized PC, only positive Cluster of Differentiantion 82 protein (CD82+) correlated with a higher survival rate. CTC count and AR-V7 expression showed itself to be a valuable biomarker for survival in metastatic PC and response to ARS-inhibitors. CTC diagnostic performance for localized PC or for screening and early detection is not high enough to show additional value over the other biomarkers.

Molecular thermodynamic modeling of surface tension: Extension to molten polymers

A combined molecular thermodynamic model with an equation of state was successfully extended for correlating the surface tension of 7 molten polymers. The model was coming from the combination of a statistical mechanical expression according to Fowler-Kirkwood-Buff approximation with the perturbed hard-sphere-chain equation of statistical association fluid theory by an attractive term of Yukawa tail. The systems under study were of homopolymers type including Poly(ethylene oxide), High-Density Poly(ethylene), Poly(dimethyl siloxane), Poly(vinyl methyl ether), Poly(ethylene glycol), Atactic-Poly(propylene glycol), and Isotactic-Poly(propylene glycol). The model also used the dipole moment of the monomer molecule of those systems as an adjustable coefficient. The model was able to correlate 65 surface tension data points of the above-mentioned polymers in 297–532.2 K range with the average absolute relative deviation (AARD) of 2.00%. In addition, a single layer neural network comprising two input parameters (temperature and soft-core diameter of Lennard-Jones fluid) and 11 neurons was applied to complete the research, achieving more than satisfactory results with the AARD of 0.88%.
