Preferences at City and Rural Beaches: Are the Tourists Different?

ABSTRACT Dodds, R. and Holmes, M.R. , 2020. Preferences at city and rural beaches: Are the tourists different? Journal of Coastal Research, 36(2), 393–402. Coconut Creek (Florida), ISSN 0749-0208. Visiting a beach is one of the most popular tourist activities and one that draws people to the surrounding area. Although much literature has been written on tourism, little examines preferences for visitor behavior in a rural versus urban setting or whether that behavior is linked to environmental management of the setting. To this end, this paper examines tourists' motivations to visit beaches, as well as their experiences, perceptions, demographics, and desires, all within the context of the tourists' geographic orientation (i.e. urban vs. rural). Drawing on responses from 1664 quantitative surveys from Ontario beaches in Canada, this research found that beachgoers to rural beaches were more likely to have higher income levels but lower levels of education than city beachgoers. Rural beachgoers were also more likely to spend more per trip, as well as having higher levels of overall satisfaction. Findings also show that beachgoers to both rural and city beaches would be more willing to make the Blue Flag environmental management designation a component of their future beach going decision if they were aware of which beaches had the certification. The outcomes of this research have implications for beach destinations, tourism organizations, and municipalities, enabling them to better understand beachgoers and derive targeted marketing strategies.
Commentary: Automated Diagnosis and Gleason Grading of Prostate Cancer – Are Artificial Intelligence Systems Ready for Prime Time?

The field of pathology is transforming with the emergence of new tools and technologies such as digital and computational pathology and artificial intelligence (AI). [1‐3] This is also an exciting time in advanced diagnostics with the more widespread use of digital imaging in pathology, in particular, the validation and regulatory approvals and increasing use of whole‐slide imaging (WSI) technology. [4] WSI allows the scanning of the entire glass slides, with an outputting of an image file that is a digitized reproduction of the glass slide with images that boast diagnostic quality standards. [4] In addition, in the past 5 years, we have witnessed an increasing use of machine learning (ML), deep learning (DL), and AI tools in clinical and translational pathology. [1,5]
Assessment of Pathogenic Potential, Virulent Genes Profile, and Antibiotic Susceptibility of Proteus mirabilis from Urinary Tract Infection

Proteus mirabilis is the third most common bacterium that can cause complicated UTI, especially in catheterized patients. Urovirulence genes of P. mirabilis strains are poorly identified among UTI patients. The aims of the present study were to determine the prevalence of the uropathogenic P. mirabilis strains isolated from UTI patients by the detection of several P. mirabilis virulence genes and to characterize the antibiotic susceptibility profile of P. mirabilis isolates. P. mirabilis isolates were collected from urine specimens of patients suffering from UTI. Virulence genes in P. mirabilis, namely, hpmA, hpmB, rsbA, luxS, ureC1, hlyA, rpoA, atfA, atfC, mrpA, and pm1 were detected in the isolates via PCR detection method. All P. mirabilis virulence genes were detected in more than 90% of the isolates except hlyA gene, which was detected in only 23.8% of the isolates. The rate of susceptibility for ceftriaxone was 96.8%, followed by norfloxacin (82.5%), gentamicin (71.4%), ciprofloxacin (69.8%), cephalexin (52.4%), nalidixic acid (42.9%), sulfamethoxazole (39.7%), ampicillin (36.5%), and nitrofurantoin (3.2%). Significant associations (P < 0.05) were detected between antimicrobial susceptibility of each of the following antibiotics and the presence virulence genes. Cephalexin antimicrobial susceptibility was significantly associated with the presence each of ureC1 and atfC. Sulfamethoxazole antimicrobial susceptibility was significantly associated with the presence atfA. Ceftriaxone antimicrobial susceptibility was significantly associated with the presence each of hpmA, ureC1, rpoA, atfC, mrpA, and pm1. Nitrofurantoin antimicrobial susceptibility was significantly associated with the presence each of hpmA, ureC1, rpoA, atfA, atfC, mrpA, and pm1. In conclusion, an association between the presence of urovirulence genes of P. mirabilis and increasing P. mirabilis resistance to antimicrobials has been demonstrated.
Safety and Outcomes of Permanent and Retrievable Inferior Vena Cava Filters in the Oncology Population

Background The role for inferior vena cava (IVC) filters in the oncology population is poorly defined. Objectives Our primary endpoint was to determine the rate of filter placement in cancer patients without an absolute contraindication to anticoagulation and the rate of recurrent VTE after filter placement in both retrievable and permanent filter groups. Patients/ Methods A single-institution, retrospective study of patients with active malignancies and acute VTE who received a retrievable or permanent IVC filter between 2009-2013. Demographics and outcomes were confirmed on independent chart review. Cost data were obtained using Current Procedural Terminology (CPT) codes. Results 179 patients with retrievable filters and 207 patients with permanent filters were included. Contraindication to anticoagulation was the most cited reason for filter placement; however, only 76% of patients with retrievable filters and 69% of patients with permanent filters had an absolute contraindication to anticoagulation. 20% of patients with retrievable filters and 24% of patients with permanent filters had recurrent VTE. The median time from filter placement to death was 8.9 and 3.2 months in the retrievable and permanent filter groups, respectively. The total cost of retrievable filters and permanent filters was $2,883,389 and $3,722,688, respectively. Conclusions The role for IVC filters in cancer patients remains unclear as recurrent VTE is common and time from filter placement to death is short. Filter placement is costly and has a clinically significant complication rate, especially for retrievable filters. More data from prospective, randomized trials are needed to determine the utility of IVC filters in cancer patients.
Condition monitoring of wind turbines based on analysis of temperature-related parameters in supervisory control and data acquisition data

In order to conduct a further in-depth exploration of the role of temperature-related parameters in the condition monitoring of wind turbines, this paper proposes a method to assess the condition of wind turbines by analyzing the supervisory control and data acquisition system temperature-related parameters based on existing research. A prediction model of time-sequence regression is established, based on the key temperature signals of WTs, so as to reflect their health condition in the form of prediction residuals. A kind of health index from the perspective of temperature-related parameters is developed by separating the statistics concerning the conformity of the predicted values of key temperature parameters within a certain time window from the measured values in order to clearly present the implied information on the health condition of wind turbines contained in the model prediction residuals. The case study shows that the trend of health index from the perspective of temperature-related parameters is consistent with the health condition of wind turbines. In some instances, its decline obviously occurs earlier than the maintenance provided to address the stoppage, suggesting that such indexes can effectively reflect some early health problems of the wind turbines to provide a reference for their scientific maintenance.
Linear theory for the mechanics of third-gradient continua reinforced with fibers resistance to flexure

A linear model, framed in the setting of the second strain gradient theory, is presented for the mechanics of an elastic solid reinforced with fibers resistant to flexure. The kinematics and bending resistance of the fibers are formulated via the second and third gradient of the continuum deformation. The corresponding Euler equations and admissible boundary conditions are then obtained by means of iterated integration by parts and variational principles arising in the third gradient of virtual displacement. In particular, within the prescription of superposed incremental deformations, we derive a compatible linear model from which a complete analytical solution describing the deformations of fiber composites is obtained. The proposed linear model predicts smooth and dilatational shear angle distributions over the domain of interest, which are also aligned with the results obtained from the corresponding nonlinear theory.
A long short-term memory neural network approach for the hardware-in-the-loop simulation of diesel generator sets

The electronic speed governor plays an important role in diesel generator sets. The ideal method for developing and debugging the electronic governor is to simulate the diesel engine’s dynamic characteristics with the hardware-in-the-loop simulation system. In this system, the diesel engine can be replaced by a mathematical model. Our research proposed a novel diesel engine modeling method using the long short-term memory neural network for simulating dynamic characteristics of the rotational speed of diesel generator sets. The proposed model is trained and tested on the data of the real diesel generator sets. With different power loads and unloads, experimental results demonstrated that this method was able to successfully simulate the dynamic characteristics of diesel generator sets. In addition, comparing to other existing methods provided a conclusion that the performance of the model was better than others. Finally, the proposed model was deployed on an established hardware-in-the-loop simulation system. The results further demonstrated that this model was able to reproduce the diesel generator sets’ dynamic characteristics.
Study on the effect of leading and trailing-edge serrations on flat-plate broadband noise

The results of a comparative study on the reduction of broadband noise for several combinations of a flat plate with serrations encountering a low-turbulence fluid flow are computed and documented. The four combinations under study are triangular serrations on leading-edge only, triangular serrations on trailing-edge only, triangular serrations on the leading and trailing edges, and ogival serrations on the leading and trailing edges. Serrations based on the trailing edge are normalized in terms of its chord length. A computational study was carried out using computational fluid dynamics models to simulate the variety of serrated flat plates. Commercial computational fluid dynamics software ANSYS Fluent 16.0 was used. A quantifiable reduction in the broadband noise was found in most of the variations in the serrated geometries. The particular case of the serrations considered in the present study having triangular serrations on both leading and trailing edges of the flat plate proved to be the most effective in terms of broadband noise reduction.
Inline-Computertomographie zur automatisierten Bauteilbewertung im Takt der Fertigung

Zusammenfassung Der Zylinderkopf und das Kurbelgehäuse gehören zu den meist beanspruchten Gussbauteilen im Verbrennungsmotor. Die hohe Funktionsintegration und der gleichzeitige Wandel der Automobilindustrie zum Leichtbau führen zu geometrisch hochkomplexen sowie mechanisch und thermisch stark belasteten Gussbauteilen. Die Inline-Computertomographie (CT) wird eingesetzt, um die geforderte Auslieferqualität jedes Bauteils im Takt der Fertigungslinie zu garantieren. Die Herausforderung bei der Prüfung besteht in der geringen zur Verfügung stehenden Prüfzeit. Der Takt der Fertigungsstraße, welcher teilweise weniger als eine Minute beträgt, gibt den Zeitrahmen für die Prüfung vor. Eine weitere zu bewältigende Aufgabe entsteht durch den Herstellungsprozess der Bauteile. Der eingesetzte Kokillenguss führt zu individuellen Abweichungen jedes Bauteiles von der Idealgeometrie, was den einfachen Vergleich zur Sollgeometrie unmöglich macht. Durch den Einsatz der CT-Prüfung können diese Abweichungen aufgezeigt, analysiert und bewertet werden. Die umfangreiche Analyse der Zylinderköpfe und Kurbelgehäuse in Kombination mit einem fehlenden Standard für die CT-spezifische Defektauswertung führen zu einem enorm hohen manuellen Aufwand. Der Einfluss des jeweiligen Mitarbeiters prägt dabei ein stark subjektiv beeinflusstes Prüfergebnis für jedes Bauteil. Die im Folgenden beschriebenen Weiterentwicklungen beziehen sich auf die automatische Analyse und Bewertung durch ein Inline-CT für Zylinderköpfe. Im Ergebnis kann eine effiziente Qualitätssicherung bei gleichzeitiger Reduktion des menschlichen Einflusses bei der Bauteilbewertung erreicht werden.
Relationships between serum procalcitonin level, severity and different stresses of non-septic critically ill patients

Abstract Background: To explore the relationships between serum procalcitonin (PCT) level, severity and different stresses of non-septic critically ill patients. Materials and Methods: Patients were divided into traumatic stress, stroke-induced stress and non-infectious inflammatory stress groups. According to 28-day prognosis, they were divided into survival and death groups. The factors affecting prognosis were studied by multivariate logistic regression analysis. Results: PCT level was significantly positively correlated with Acute Physiology and Chronic Health Evaluation II (APACHE II) and sequential organ failure assessment (SOFA) scores (P=0.001). The PCT level and abnormality rate of the traumatic stress group significantly exceeded those of other groups (P---lt---0.05). The APACHE II score, SOFA score and 28-day mortality rate of traumatic stress and stroke-induced stress groups significantly exceeded those of the non-infectious inflammatory stress group (P---lt---0.05). The PCT level, APACHE II score and SOFA score of the death group significantly surpassed those of the survival group (P---lt---0.05). With rising PCT level, APACHE II score, SOFA score and 28-day mortality rate all increased, with significant intergroup differences (P---lt---0.01). Multivariate logistic analysis showed that serum PCT level, APACHE II score and SOFA score were independent risk factors for prognosis. The area under ROC curve for prognosis evaluated by PCT level was 0.797 (95%CI = 0.710~0.878, P=0.000). At a 4.3 μg/L cut-off, the sensitivity and specificity for predicting 28-day mortality were 87.4% and 78.1%, respectively. Conclusion: The serum PCT level of non-septic critically ill patient was positively correlated with severity, which was more likely elevated by traumatic stress than other stresses.
Structural characterization, antioxidant and cytotoxic effects of iron nanoparticles synthesized using Asphodelus aestivus Brot. aqueous extract

Abstract ASP was used to synthesize FeNPA. They were characterized by UV-vis spectroscopy, FT-IR, TEM, SEM, XRD and ZP. The aim of this study was to evaluate in vitro cytotoxic activity and antioxidant acitivities of FeNPA and ASP. The antioxidant properties were evaluated using DPPH, ABTS+ and H2O2 assays. FeNPA had higher antioxidant activity comparing to ASP according to DPPH (IC50: 3.48 μg/mL) and ABTS+ (60.52%) assays. Anti-cancer activities of FeNPA and ASP were investigated in breast cancer, melanoma and control cell lines. FeNPA was more cytotoxic than ASP in MCF-7, MeWo, CHL-1, and HEL 299 cells. FeNPA had shown that mitochondria induce apoptosis through stress in MDA-MB-231, and cells MeWo. ASP also induced apoptosis 2.23-fold in MCF-7 cells. Progesterone receptor gene expression showed a 10-fold increase in a hormone-dependent MCF-7 cell line in ASP, and FeNPA treatment. Expressions of BCL6, CXCL12, DNAJC15, RB1 and TPM1 in melanoma cancer cell lines were significantly increased in ASP and FeNPA administration. It had been shown that FeNPA regulates gene expressions that may be considered important in terms of prognosis in breast cancer and melanoma cell lines and it is suggested that gene expressions regulated by FeNPA are also evaluated in animal models in vivo.
Roller Massage: Comparing the Immediate Post‐Treatment Effects Between an Instructional Video and a Self‐Preferred Program Using Two Different Density‐Type Roller Balls

Abstract The aims of this study were to (1) compare the immediate post-treatment effects of an instructional video versus a self-preferred program on the hip range of motion and a pressure pain threshold using two different density roller balls, and (2) compare the effects of the two roller balls on those variables. Forty adults were randomly allocated into four groups: (1) MB1-video, (2) MB1-self-preferred, (3) MBX-video, and (4) MBX-self-preferred. Participants followed a video or a self-preferred program using either a moderate (MB1) or a hard (MBX) density ball. Main outcomes were passive hip internal rotation, external rotation, and a pressure pain threshold. For MB1, the video produced greater outcomes than the self-program for external rotation (10◦ versus 2◦), internal rotation (7◦ versus 2◦), and the pain threshold (210 kPa versus 44 kPa). For MBX, the video produced greater outcomes than the self-program for external rotation (8◦ versus 1◦), internal rotation (5◦ versus 1◦), and the pain threshold (184 kPa versus 30 kPa). When comparing roller balls, the MB1 produced greater outcomes than the MBX for external rotation (10◦ versus 8◦), internal rotation (7◦ versus 5◦), and the pain threshold (210 kPa versus 184 kPa) with the video. For the self-preferred program, the MB1 produced greater outcomes for external rotation (2◦ versus 1◦), internal rotation (2◦ versus 1◦), and the pain threshold (44 kPa versus 30 kPa). The instructional video and a moderate density ball produced greater immediate post-treatment outcomes than the self-program and a hard density ball. Professionals should consider using the video to teach technique and match clients to a specific density-type roller ball.
Lower Extremity Stiffness in Collegiate Distance Runners Pre- and Post-Competition

Abstract Previous evidence has suggested that there is a relationship between leg stiffness and improved running performance. The purpose of this investigation was to determine how leg stiffness of runners was influenced in the 24 and 48 hour period following a cross country race. Twenty-two collegiate cross-country runners (13 males, 9 females, 19.5 ± 1.4 yr) were recruited and participated in the study. Leg stiffness was assessed 24 hours before and after a race as well as 48 hours post-race. Three jumping protocols were conducted: 1) a static jump, 2) a countermovement jump, and 3) a vertical hopping test. Two embedded force plates (1000 Hz) were utilized to measure ground reaction forces for each test and a metronome was utilized to maintain hopping frequency (2.2 Hz). A significant main effect was found for a static jump, a countermovement jump and leg stiffness. Leg stiffness was significantly reduced 24 hours post-race (pre-race 36.84 kN·m-1, 24h post 33.11 kN·m-1, p < 0.05), but not 48 hours post-race (36.30 kN·m-1). No significant differences were found in post-hoc analysis for the squat jump, countermovement jump height and the eccentric utilization ratio. Following a cross-country race, leg stiffness significantly declined in a group of collegiate runners in the immediate 24 hours post-race, but returned to baseline 48 hours post-race. Sport scientists and running coaches may be able to monitor leg stiffness as a metric to properly prescribe training regiments.
How do Romanian Youths Fare in Their Journey from School to Work?

Abstract The paper attempts to present a comprehensive picture of the main characteristics of Romanian university-educated youths in their journey to employment. The persisting demographic decline and significant labor shortages point out to the importance of having an effective transition from school to work (as reflected in several Europe 2020 policy targets) so that youth and young adult cohorts are able to contribute to the Romanian economy to the full extent of their abilities. Analysis of the latest data available reveals that Romanian university graduates’ path to employment often involves a complete switch from study to work. Despite a lack of previous work experience, they enjoy high employment rates, relatively long job tenure that starts on, or shortly after, graduation, and have jobs that match their education. They also tend to be proactive in their job search and over 90% are not willing to change residence in order to start employment. Inactivity patterns that consider both work and education, and early leavers from education show significant fluctuations during the economic cycle. Results indicate the strong and weak areas with respect to labor market integration of youths and young adults, and can provide a starting point for policies to optimize their successful integration. It also points out to potential research areas to address key aspects of transitions from school to work that may clarify unsolved issues and guide effective policy interventions.
Analysis of 5-hydroxytryptamine and its related indoles in cerebrospinal fluid of leukemic children by gas chromatography-mass spectrometry

Abstract Background It is meaningful to quantify some neurotransmitters in cerebrospinal fluid (CSF) for pathology and clinical diagnosis. The objective of this study was to develop a rapid and reliable method for detecting 5-hydroxyindole ethanol (5-HTOL), 5-hydroxyindole acetic acid (5-HIAA), 5-hydroxytryptophan (5-HTP) and 5-hydroxytryptamine (5-HT) in CSF by gas chromatography-mass spectrometry (GC-MS), and explore the clinical significance of the levels of these neurotransmitters in CSF from acute lymphoblastic leukemia (ALL). Methods The levels of 5-HTOL, 5-HIAA, 5-HTP and 5-HT in CSF from children with ALL and a control (CON) group were examined by the proposed GC-MS method. Results The GC-MS method showed good sensitivity and accuracy. 5-HT and 5-HIAA contents in the ALL group were significantly lower than those in the CON group (p < 0.01), while there was no significant difference in 5-HTP and 5-HTOL contents between the two groups (p > 0.05). Conclusions This sensitive and reliable method could be used in studies focusing on clinical pathogenesis of ALL.
