Developing a Model to Study Walking and Public Transport to Attractive Green Spaces for Equitable Access to Health and Socializing Opportunities as a Response to Climate Change: Testing the Model in Pu’er City, China

Green space is not always equitably located in cities, and the attractiveness of green space varies, leaving some residents with easy access to high-quality parks and others with little or no access or access to under-maintained parks. To remedy these inequities, this study identified attractive and well-utilized recreational green spaces and developed a model to measure the likelihood of using these recreational green spaces (PSG). The goal was to reduce the travel time and cost of walking or using public transportation to get to green spaces and to design all green spaces to be attractive. The data come from the perspective of the city’s public transportation system and residents’ personal choices. First, the attractiveness of recreational green spaces was calculated from big data on the geolocation of cell phones, measuring the level of provision of recreational green spaces and the trip rates of urban residents. After that, the travel cost to reach recreational green space in residential areas was calculated according to residents’ travel habits. Finally, the probability of all recreational green spaces in the city being used was calculated by combining the population size of residential areas. Taking Pu’er City in China as an example, the attractiveness and utilization rates of recreational green spaces were calculated by PSG, and the results of the study showed that the probability of residents choosing to use the recreational green spaces that are closer to the residential area, with a larger population capacity, and with a higher attractiveness is the highest. The results of the study help promote equitable access to health and socialization opportunities for individuals and communities, thereby promoting environmental justice to help mitigate and respond to climate change.

Evaluating the Attraction of Scenic Spots Based on Tourism Trajectory Entropy.

With the development of positioning technology and the widespread application of mobile positioning terminal devices, the acquisition of trajectory data has become increasingly convenient. Furthermore, mining information related to scenic spots and tourists from trajectory data has also become increasingly convenient. This study used the normalization results of information entropy to evaluate the attraction of scenic spots and the experience index of tourists. Tourists and scenic spots were chosen as the probability variables to calculate information entropy, and the probability values of each variable were calculated according to certain methods. There is a certain competitive relationship between scenic spots of the same type. When the distance between various scenic spots is relatively close (less than 8 km), a strong cooperative relationship can be established. Scenic spots with various levels of attraction can generally be classified as follows: cultural heritage, natural landscape, and leisure and entertainment. Scenic spots with higher attraction are usually those with a higher A-level and convenient transportation. A considerable number of tourists do not choose to visit crowded scenic destinations but choose some spots that they are more interested in according to personal preferences and based on access to free travel.

Attractant and repellent properties of Senna didymobotrya plant extracts to Amblyomma variegatum and Rhipicephalus appendiculatus

The growing challenge of acaricide resistance and geographical range expansion of invasive tick species demands other interventions, like plant-based alternatives, for sustainable tick control. Leaves, flowers, seedpods, and twig branch extracts of Senna didymobotrya were analyzed using coupled gas chromatography mass spectrometry (GC-MS). Response of adult Amblyomma variegatum and Rhipicephalus appendiculatus to extracts was evaluated. The most attractive plant extract was fractionated and ticks’ responses to its fractions assessed. Potential tick attractants in the attractive plant part extract and its fractions were identified by GC-MS analysis. Non- significant qualitative and quantitative differences were observed in the plant parts’ extract composition (R = 0.6178). Flower extracts attracted both species, with a 0.1-fold higher attraction in A. variegatum compared to the standard attraction aggregation attachment pheromone (AAAP). Leaf and seedpod extracts repelled ticks at various concentrations. Bioassays after fractionating flower extracts identified hexane and ethyl acetate fractions as most attractive to A. variegatum (P < 0.001) and R. appendiculatus (P < 0.001), respectively. Chemical analysis of the most attractive extracts and fractions identified compounds, including documented acarine attractants, squalene and linoleic acid. A squalene and linoleic acid blend (1:1) at 1 mg/mL significantly attracted adult A. variegatum (P < 0.01) and R. appendiculatus (P < 0.001). The results of this study broaden comprehension of how ticks respond to plants in nature, and showcase the promising potential for integrating these insights into effective tick management programs.

Phototactic response of angoumois grain moth Sitotroga cerealella (olivier) to visible spectrum: Attraction analysis and modelling using machine learning

The Angoumois grain moth Sitotroga cerealella (Olivier), a primary pest of food grain storage, poses serious problems in India and many other countries. The insect's stronger phototaxis behaviour has been studied using monochromatic wavelengths in the visible spectrum. Among the different wavelengths (250, 330, 410, 480, 530, 580, and 680 nm) assessed for attraction under laboratory conditions, the highest attraction was observed for the blue wavelength (480 nm). Subsequently, the impact of luminance intensities (60, 80, and 100 lux) at each wavelength was also determined. At 60 lux, the 480 and 250 nm wavelengths attracted significantly more adults, i.e., 91.67% and 85%, respectively. The 680 nm wavelength exhibited the lowest attraction rate of only 15% at 100 lux. A gender-based analysis of S. cerealella adults demonstrated that female moths showed a significantly lower attraction (1:3.5) than male moths. This attraction behaviour was also predicted using machine learning. Among the different machine learning algorithms used for modelling insect behaviour, artificial neural network produced the highest prediction with an R2 value of 0.96. In conclusion, the results suggest that using the 480 nm wavelength may be an effective option for mass trapping and monitoring of S. cerealella.

Attractiveness of municipalities in Minas Gerais for the installation of forest-based companies

This paper measured the attractiveness of municipalities in the state of Minas Gerais (MG) for projects in the steel, cellulose and paper, furniture, energy and wood panel industry segments. A questionnaire was used to construct an index of attractiveness of the forestry sector for each municipality. As a result, it was found that 40% of the municipalities presented “average” or higher attractiveness. The mesoregions with the greatest potential for forestry development were the Metropolitan region of Belo Horizonte, Southwest of Minas and Zona da Mata. The steel and cellulose and paper segments found attractive factors in 74.08% and 72.79% of the municipalities, respectively. It was concluded that the methodology applied showed how close a location was to meeting the characteristics of forest-based industries. It is expected to encourage future research and influence strategic planning for the expansion of the forestry sector across the country.

Инфраструктурный потенциал туристских дестинаций Волгоградской области

The purpose of this article is to assess the infrastructural potential of tourist destinations, i.e., localized types of tourism, in the Volgograd region. In general terms, the infrastructural potential of tourist destinations is understood as a set of conditions for the transfer and accommodation of tourists. The methodological basis is an integrated approach to the concept of “infrastructural potential,” comparative geographic analysis, geoinformational modeling, and cartographic modeling. The integrated character of the paper is manifested in the identification of components of infrastructure potential, such as territorial factors, the potential of the population, the provision of collective accommodation facilities, and the state of transport infrastructure, the analysis of which is based on official statistics for the period 2002–2022. The territorial units for studying the infrastructure potential are the administrative districts of the Volgograd region; thus, comparative and geographical principles are used. To identify the spatial features of the development of tourism infrastructure using geographic information systems, the cartograms were constructed and analyzed, which illustrate the location of tourist and recreational enterprises and the tourist and recreational attractiveness of administrative districts of the region. The methods and statistical data used made it possible to reveal the uneven development of the tourist infrastructure. The districts of the Volgograd region were ranked according to the degree of tourist attractiveness: low one had 20 districts, medium one had 12 districts, high one had 1 district (Sredneakhtubinsky), and the city of Volgograd had the highest attractiveness. In spatial terms, the main axis of the development of tourist infrastructure was identified, including 7 administrative districts located along the right bank of the Volga and confined to the Volga-Aktuba flood plain; some border areas, Kotelnikovsky, Uryupinsky, Serafimovichsky, and Pallasovsky, have an medium tourist attractiveness. The majority of the districts in the center of the region and the left bank of the Volga have a low tourist and recreational attractiveness. A component-by-component analysis and a capacity assessment of the potential of tourist destinations, especially in the context of administrative regions, make it possible to identify the leading factors in the territorial development of the tourism and recreational spheres and to develop tourism and recreational systems in the future.

Tourist Interests as a Basis for Post-Covid-19 Pandemic Tourism Visit Recovery Planning: Studies in the Ecotourism Area of Way Kambas National Park, Lampung Province

Ecotourism is expected to revive in the post COVID-19 pandemic, as currently the lowland conservation area with the highest biodiversity in the world is Way Kambas National Park, Lampung province, Indonesia. Attractiveness is the main variable as the basis for planning the restoration of tourist visit performance. The purpose of this study was to determine the role of the country of origin variable and demographics of respondents in the attractiveness of ecotourism objects in WKNP. As a result, from May 2022 to August 2022, a 15-minute video about the exoticism of WKNP had been uploaded on the https://research-mil.unila.ac.id/ site. At the end of the video, a questionnaire is presented in Indonesian, English, French, Korean, Japanese, Chinese, and Arabic. The Ordinal Logistic Regression Postulate is used at the 95% confidence level. There are three levels of response variables that score 0, 1, and 2 to express not interested, interested, and very interested in visiting WKNP, respectively. The predictor variable is the respondent’s characteristics, which include the respondent’s origin, age, gender, number of dependents, income, and professional group. Optimization of model parameters and hypothesis testing were carried out at a 95% significance level using Minitab 19 software. The results showed that the attractiveness of visiting was influenced by: (a) country of origin, 33.09 times more foreign respondents compared to domestic ones with P = 0.037; (b) those who are 1 year older have a higher attractiveness, namely 1.06 times; and (c) whose professions as teachers, civil servants, and professional workers are lower, namely only 0.08 times, 0.09 times, and 0.14 times compared to housewives or students. The policy implications for redeveloping plans to improve tourist interest in visiting WKNP need to be focused on prospective tourists from abroad, with the main target being professions other than civil service employees.&#x0D; Keywords: demographic, overseas, post-pandemic, and logistic ordinal regression

Fermenting molasses and a synthetic odour blend to attract blood-fed Anopheles coluzzii.

Collecting blood-fed mosquitoes to monitor pathogen presence or to gather information on the host blood meal is often challenging. Fermenting molasses can be used to produce carbon dioxide to attract host-seeking mosquitoes, however, earlier work indicated that it may also attract blood-fed mosquitoes in the field. In the current study, these field results were validated in an experimental setting using a large cage setup with Anopheles coluzzii (Diptera, Culicidae). Blood-fed mosquitoes were indeed attracted to fermenting molasses with the highest attraction at 72 hours post feeding, which was used for subsequent experiments. Next, it was tested if fermentation of molasses is required for attraction, and whether it acts as an oviposition attractant, increases egg laying, or increases mosquito survival. The compounds that could be responsible for attraction were identified by combined electrophysiology and chemical analyses and formulated into a synthetic blend. Fermenting molasses attracted blood-fed mosquitoes in the large cage study, while fermenting sugar and non-fermenting molasses did not. The fecundity of blood-fed mosquitoes increased after feeding on fermenting molasses, however, compounds emanating from molasses did not trigger oviposition. The synthetic blend attracted blood-fed mosquitoes and may be used to determine mosquito host selection and for xenomonitoring, as 'flying syringes' to detect non-vector borne pathogens.

Gravity Model for Flow Migration Within Wireless Communication Networks

This paper investigated an Iraqi dataset from Korek Telecom Company as Call Detail Recorded (CDRs) for six months falling between Sep. 2020-Feb. 2021. This data covers 18 governorates, and it falls within the period of COVID-19. The Gravity algorithm was applied into two levels of abstraction in deriving the results as the macroscopic and mesoscopic levels respectively. The goal of this study was to reveal the strength and weakness of people migration in-between the Iraqi cities. Thus, it has been clear that the relationship between each city with the others is based on and of mobile people. However, the COVID-19 effects on the people’s migration needed to be explored. Whereas the main function of the gravity model is to clarify the migration flows through modeling spatial interaction. This was implemented using Python scripting language. It is concluded that the gravity model has a powerful ability to analyze the movement of people between cities. According to the mean of result between governorates, showing that the highest attraction was between Babil and Anbar governorates amounted to , while the lowest attraction was between Wasit and Thi-Qar governorates with , and the others ranged between .

Interactions of boron nitride nanosheet with amino acids of differential polarity

Free amino acids represent a category of different biomolecules in the blood plasma, which bond together to make up larger organic molecules such as peptides and proteins. Their interactions with biocompatible nanoparticles are especially important for plasma-related biomedical applications. Among the various nanomaterials, the applications of carbon and boron nitride-based nanotubes/nanosheets have shown a huge increase in recent years. The effect of molecular polarity on the interaction between a boron nitride nanosheet (BNNS) and amino acids is investigated with quantum mechanical calculations by density functional theory (DFT), classical MD simulations, and well-tempered metadynamics simulations. Four representative amino acids, namely, alanine (Ala), a nonpolar amino acid, and aspartic acid (Asp), lysine (Lys) and serine (Ser), three polar amino acids are considered for their interactions with BNNS. In DFT calculations, the values of the adsorption energies for Lys-BNNS and Ser-BNNS complexes are − 48.32 and − 32.89 kJ/mol, respectively, which are more stable than the other cases. Besides, the adsorption energy calculated confirms the exergonic reactions for all investigated systems; it implied that the interaction is favorable electronically. The MD results show that the LYS molecules have a higher attraction toward BNNS because of its alkane tail in its side chain, and the ASP revealed the repulsion force originating from its COO– group. All the results are confirmed by free energy analyzes in which the LYS showed the highest adsorption free energy at a relatively farther distance than other complexes. In fact, our results revealed the contribution of functional groups and backbone of the amino acids in the adsorption or repulsion features of the studied systems.

Unequal development of municipalities: socio-economic paradox in Bulgaria

The paper aims at investigating how different municipalities in Bulgaria are developing in terms of attractiveness and competitiveness of employee's salaries. Even though some small municipalities are remote from the capital city in Bulgaria, they remain paradoxically the highest in terms of salary size. These municipalities are linked to high employability and high average salaries in comparison to other small municipalities across Bulgaria. Furthermore, the paper suggests that municipalities with big employers, particularly in oil and gas sector and energy sectors are characterised with high number of qualified employees, higher attractiveness and higher wealth than the rest of the municipalities in Bulgaria. The paper's findings show that one of the most suitable and relevant ways of reducing the unequal socio-economic development among the Bulgarian municipalities is the promotion and realisation of public private partnerships.

Amine-grafted walnut shell for efficient removal of phosphate and nitrate.

The presence of emerging pollutants such as PO43- and NO3- in water bodies has attracted worldwide concern about their severe effects on water bodies and the health of humankind in general. Therefore, to preserve the health of humankind and environmental safety, it is of the essence that industrial effluents are treated before they are discharged into water bodies. Amine functionalized walnut shells (ACWNS) were synthesized, characterized, and then tested as a novel adsorbent for PO43- and NO3- removal. The effects of pH, dosage, initial phosphate concentration, interference ions, and temperature on the removal of phosphate and nitrate were investigated. Notably, the adsorption of PO43- and NO3- was exothermic and spontaneous, with a maximum uptake capacity of phosphate and nitrate, at 293K, 82.2 and 35.7mgg-1, respectively. The mechanism by which these ions were adsorbed onto ACWNS could be electrostatic interactions and hydrogen bonding. Pseudo-second-order kinetic modelfitted the PO43- and NO3- adsorption, while Freundlich and Langmuir models best fitted the PO43- and NO3- adsorption, respectively. Furthermore, in the binary system, the uptake capacity of phosphate decreased by 14.4% while nitrate witnessed a reduction in its uptake capacity of 10.4%. ACWNS has a higher attraction towards both ions and this could be attributed to the existence of a variety of active areas on ACWNS that exhibit a degree of specificity for the individual ions. Results obtained from real water sample analysis confirmed ACWNS as highly efficient to be utilized for practical remediation processes.

Investment Bank Competition in Indonesia

We collect samples from the annual reports of 5 investment banks in Indonesia from 2000 to 2020 as data and samples from our research. We find that cost has the lowest effect compared to other indicators with a Optimized Weight of 1.8% and market making activity is the most influential indicator of competitiveness with a Optimized Weight of 22.5%. Market making provides the greatest attraction to clients in the investment bank business because in the market business it is the most important thing so that the ability of investment companies in market making to obtain capital for clients is the highest attraction because it can meet client needs related to capital. Costs correlated with reputation and costs in the investment bank business are almost the same from one bank to another so that the efficiency or ability of investment banks in providing the best prices does not provide a strong enough appeal to clients. This is also influenced by the investment bank market segment, which is a company segment that has large enough wealth assets so that costs are not too much of a problem for the client as long as it is rational and profitable.

Hospital Patients’ migration among Italian Regions

Abstract Background At the beginning of the 2000s the federalization of the Italian National Health Service gave to the Regions greater financial and political responsibility: 21 Regional Health Services were set up with administrative and planning independence. They are in a potential competitive regime, since the citizens are free to choose their place of treatment. The aim of our research was to analyze fulfillment of needs for hospital services on site and Patients' migration to hospitals of other Regions. Methods We conducted an observational cross sectional study on Hospital Discharge Cards provided by the Ministry of Health, upon specific request, from 2013 to 2017. The subjects of the analysis (catchment areas) were the hospital networks of Italian Regions. Interregional flows were carried out from data of Residents, Attractions and Escapes, which were developed through Attraction and Escape Indexes. Graphic representation was produced with Gandy's Nomogram. Results In the studied period, we observed an important decrease in hospitalizations and a simultaneous increase in interregional mobility. At the same time, admissions to hospital managed by Local Health Authorities and to Private Clinics increased. According to the Major Diagnostic Categories the main causes of hospitalizations in mobility were Musculoskeletal System And Connective Tissue Diseases (MDC 8), Cardiovascular System Diseases (MDC 5), Nervous System Diseases (MDC 1) and Digestive System Diseases (MDC 6). There were discrepancies between the Regions of Northern/Central Italy (higher Attraction Indexes) and Southern Italy (higher Escape Indexes). According to Gandy's Nomogram only nine Regions showed a good public hospital planning: Lombardy, A.P. of Bolzano, Veneto, Friuli V.G., E. Romagna, Tuscany, Umbria, Latium and Molise. Conclusions The North/Centre Regions have a public hospital planning able to be better to meet the care needs of their citizens and to attract Patients than the South ones. Key messages The study of Patients’ mobility is relevant in order to evaluate equity and quality of care provided by different Italian Regions. Patients' mobility has also an important economic implications.

Li-Ion Electrode Microstructure Evolution during Drying and Calendering

The complicated microstructure of a Li-ion electrode is the result of intrinsic material properties and fabrication steps. This work presents experiments and simulations that illuminate microstructure evolution during the drying and calendering fabrication steps and highlights important factors during manufacture of a high-power electrode.Li-ion material interactions include self-interactions and interactions with other materials. For example, smaller active particles can have higher attraction, which makes them more susceptible to form agglomerates. Therefore, manufacturing processes are modified to account for such material interactions to make coatings that are uniform and minimize surface defects and potential delaminations. During mixing and coating operations, deficiencies are more visually apparent, whereas defects generated during the processes of drying and calendering may not be as obvious.Different and sometimes opposing theories attempt to explain microstructure changes during the drying step. A well-known theory is binder migration, proposing that movement of the solvent during evaporation redistributes the carbon and binder. In this work, binder migration and other theories are investigated quantitatively and compared to new experimental and simulation results.The spatially-resolved ionic and electronic conductivity properties of an electrode containing nickel manganese cobalt (NMC) active material were experimentally determined. In simulation, a multi-phase smoothed particle model developed within LAMMPS was used to simulate all of the mixing, coating, drying, and calendering processing steps.Results show that increased drying temperature can have negative effects such as decreased ionic (Figure 1) and electronic conductivities for two NMC cathodes with identical compositions that are mixed and coated through the same processes but dried at two different temperatures.The calendering process can also change the microstructure in unexpected ways. Our work shows that the pressure of calendering causes redistribution of the soft and small carbon/binder domains. This non-uniformity, in turn, changes the overall transport properties of the Li-ion electrode.Figure 1. Ionic conductivity maps of two uncalendered NMC cathodes reflecting the difference between the samples dried at (a) 20 °C and (b) 150 °C. Figure 1

Going green: increasing organizational attractiveness via sustainable practices and environmentally-conscious recruitment

Purpose This paper aims to review the latest management developments across the globe and pinpoint practical implications from cutting-edge research and case studies. Design/methodology/approach This briefing is prepared by an independent writer who adds their own impartial comments and places the articles in context. Findings In an increasingly environmentally aware world, businesses are progressively obliged to mitigate harmful effects of their operations on the environment. Integrating sustainable practices with human resource management leads to environmentally aware employees. Green human resource management (GHRM) practices can be used in the recruitment process to attract quality prospective employees. A company with higher GHRM appears a more reputable and responsible employer and has higher attractiveness to candidates. They in turn have higher job pursuit intentions. This is strengthened when the candidate themselves has high environmental values and attitudes, leading to better person-organization fit, increased performance and competitor advantage. Originality/value The briefing saves busy executives and researchers hours of reading time by selecting only the very best, most pertinent information and presenting it in a condensed and easy-to-digest format.

UJI DAYATARIK TIGA MERK ATRAKTAN UNTUK PENGENDALIAN HAMA LALAT BUAH (Bactrocera spp.) PADA TANAMAN SAYURAN DAN BUAH-BUAHAN

Fruit flies are an insect whose existence is very detrimental because of their role and function as the main pests for vegetable and fruit farmers. For that, we need technology that can suppress the population to increase crop production. The purpose of this study is to obtain information about the ability of three attractant brands on the market to attract male fruit flies, namely Ferokop, Petrogenol, and Milabu. This research used a quantitative exploratory method with collecting data on the number of male fruit fly imago trapped and harvested. The treatment for each type of attractant was repeated four times so that there were 12 bottles of traps in total. The harvest of fruit flies is carried out every day and counted manually using a hand counter. This data obtained were then tabulated and analyzed with ANOVA at the level significant of 5%. If there is a significant difference, then a further test is carried out with the Least Significance Different (LSD) test. The identification results showed that the Ferokop attractant had the highest attractiveness, at 337.38 catches per day, followed by the Petrogenol brand with 225.52 catches, and finally the Milabu brand with 83.05 catches. The conclusion is that the three types of attractant brands have different abilities in attracting male fruit flies.

In search of the spectral composition of an effective light trap for the mushroom pest Lycoriella ingenua (Diptera: Sciaridae)

Certain fungus gnats, like Lycoriella ingenua are notorious pests in agriculture, especially in mushroom production. While larvae cause mainly direct crop damage, adults are vectors of several dangerous fungal pathogens. To promote the development of pesticide-free management methods, such as light trapping, we measured the spectral sensitivity of L. ingenua compound eyes with electroretinography and performed two different behavioural experiments to reveal the wavelength dependence of phototaxis in this species. The spectral sensitivity of the compound eyes is bimodal with peaks at 370 nm (UV) and 526 nm (green). Behavioural experiments showed that attraction to light as a function of wavelength depends on light intensity. In our first experiment, where the minimal photon flux (105–109 photons/cm2/s) needed for eliciting a phototactic response was determined wavelength by wavelength, phototaxis was strongest in the green spectral range (~526 nm). In the other behavioural experiment, where wavelength preference was tested under a higher but constant light intensity (~1013 photons/cm2/s), the highest attraction was elicited by UV wavelengths (398 nm). Our results suggest that both UV and green are important spectral regions for L. ingenua thus we recommend to use both UV (~370-398 nm) and green (~526 nm) for trapping these insects.

Antibacterial and Antifungal Efficacy of Platelet-Rich Fibrin and Platelet-Rich Fibrin Matrix against Root Canal Microflora.

Background:Binding of such proteins with a developing fibrin mesh or to the extracellular matrix has the ability to create chemotactic gradients aiding the recruitment of stem cells, thereby, stimulating cell migration and differentiation this may promotes repair and regeneration. There is a unique concept in platelet concentrates called platelet-rich fibrin matrix (PRFM) which is processed using higher attraction without the utilization of bovine thrombin.Aim and Objectives:The aim of this study is to evaluate the antibacterial and antifungal effects of platelet-rich fibrin (PRF) and PRFM against root canal microflora.Materials and Methods:Blood samples were taken from 20 adults, age ranging from 20 to 40 years who were systemically healthy, nonsmokers with no symptoms of infection, or on antibiotics at least 3 months before experiments. The procedures and the protocols involved in the study were accepted by the Institutional Ethical Committee. Written informed consent was obtained from the donors and patients. Approximately 10 ml of blood was collected from each donor. 5 ml of blood was used for the preparation of PRF and 5 ml for PRFM.Results:The antifungal scores among the groups. The highest antifungal scores were seen in metapex followed by PRF and PRFM group. Kruskal–Wallis test was applied to check the statistical difference among the groups, and there was a statistically significant difference seen among the groups (P = 0.00). The antibacterial scores among the groups. The highest antibacterial scores were seen in Metapex followed by PRF group and PRFM group Kruskal–Wallis test was applied to check the statistical difference among the groups, and there was a statistically significant difference seen among the groups.Conclusion:PRF demonstrated antibacterial activity against passage isolates but had no antifungal efficacy. This antibacterial property may be a valuable adjunct when using PRF for regenerative procedures in endodontics. Both PRF and PRFM have to be analyzed for antimicrobial properties for extended duration and various other clinical strains with larger sample size.

Romantic Bias in Judging the Attractiveness of Faces from the Back

People tend to assign higher attractiveness to an individual viewed from the back than head on. This tendency is pronounced when males rate the attractiveness of women. This study investigated reasons for the previously observed gender difference in this bias, focusing on the social relationship between raters (participants) and rated models (stimuli). To manipulate the assumed social relationship, we explicitly instructed participants in advance to rate the front/back view of an opposite-gender individual as a romantic partner (romance-based condition) or as a friend (friend-based condition). The back-view bias was robustly observed in both male and female raters under every condition. More importantly, male raters showed an enhanced back-view bias under the romance-based condition compared to the friend-based condition, whereas female raters showed less bias, irrespective of the assumed social relationship. We discuss these results in terms of gender differences in criteria used to form judgments of attractiveness.
