A Model of the Transient Behavior of Tractive Rolling Contacts

When an elastic body of revolution rolls tractively over another, the period from commencement of rolling until gross rolling ensues is termed the prerolling regime. The resultant tractions in this regime are characterized by rate-independent hysteresis behavior with nonlocal memory in function of the traversed displacement. This paper is dedicated to the theoretical characterization of traction during prerolling. Firstly, a theory is developed to calculate the traction field during prerolling in function of the instantaneous rolling displacement, the imposed longitudinal, lateral and spin creepages, and the elastic contact parameters. Secondly, the theory is implemented in a numerical scheme to calculate the resulting traction forces and moments on the tractive rolling of a ball. Thirdly, the basic hysteresis characteristics are systematically established by means of influence-parameters simulations using dimensionless forms of the problem parameters. The results obtained are consistent with the limiting cases available in literature and they confirm experimental prerolling hysteresis observations. Furthermore, in a second paper, this theory is validated experimentally for the case of V-grooved track.
Supporting Educational Attainment : Dimensions of Motivational Beliefs and Their Scaffolding Competence and Effort Beliefs

The Adolescent Motivation for Educational Attainment Questionnaire is a 32-item questionnaire (we drew 20 items from 3 subscales of the Educational Motivation Questionnaire: Murdock, 1999) that was developed to measure multiple potential dimensions of adolescents' motivation to complete high school and enroll in post-secondary education, including competence and effort beliefs; perceived value of education: and peer, teacher, and parent support for educational attainment. We assessed a multiethnic sample (N = 569) of low-achieving students who started 1st grade together in 1 urban and 2 small city school districts. Participants were assessed over 2 consecutive years (Grades 8 and 9 given prior grade retention, or Grades 9 and 10 if not retained). Exploratory factor analyses identified 4 correlated dimensions underlying the questionnaire responses. Subsequent confirmatory factor analyses provided support for a bifactor model, which includes a general factor of students' basic educational motivation, and specific factors of (a) teacher educational expectations, (b) peer aspirations, and (c) value of education. Measurement invariance of the bifactor model was established across students' gender and ethnicity (Caucasian, African American, and Hispanic) and year of testing. Criterion-related validity of the general and specific factors with students' school belonging, student-teacher warmth and conflict, disciplinary practices, letter grade, conduct problems, and behavioral engagement was examined. Practical implications of the measure are discussed.
Learners re-shaping learning landscapes: New directions for old challenges?

Centre for Teaching and Learning InnovationUnitec NZThe sheer inevitability and momentum of global adoption of all forms of technology hasengendered a range of responses from wholehearted welcome and exploitation, to denialand anger . Consequently, the education landscape has been shifting, although not in thecolossal, earth-rending manner that was initially envisaged. Information, CommunicationTechnology Enhanced Learning and Teaching (ICTELT) has progressively continued toevolve and mature, embedded in an increasing foundation of research. One key benefitidentified in this process is the inclusiveness and fluidity that can be built into ICTELTexperiences, especially when they occur within a collaborative community. This paperexplores an example of how ICT was used to adapt part of an existing ‘problematic’curriculum in a way that helped address central issues, encouraged collective learning andenabled learners. In the Foundations programme at Dubai Men’s College (DMC) studentsfind the conventions of academic writing, and the requirement to improve their proficiency,challenging, especially as they are also struggling with the transition from secondary totertiary education, and their own changing identities. The framework of existingCommunities of Learning (CoL) was employed to introduce a blended, scaffolded approachthat aimed to assist students with academic writing, as well as assisting their transition tomore self-directed, confident learning. The design and implementation of the interventionsis described, and a brief overview of the results of the associated research study is given,along with recommendations for educators wishing to adopt a similar approach.Keywords: ICTELT, blended learning, communities of learning, academic writing, Gulfregion, Foundation programmes
AGE IN PEOPLE LIVING WITH HIV IN HIGH-INCOME COUNTRIES

Further researches are needed to reconcile the absence of increased mortality risk in HIV-infected individuals with controlled viral load and restored immunity with the observed higher risk of comorbidities, such as cardiovascular diseases and non-AIDS-defining cancers, and the accelerated aging hypothesis, in particular, to help stratify HIV individuals who are at risk; to define the optimal management of multimorbidity and polypharmacy, even in the absence of a higher comorbidity risk; and to better account for increased life expectancy and multimorbidity burden to plan the future needs in care for HIV-infected individuals.
Statistical analysis of arthroplasty data

It is envisaged that guidelines for statistical analysis and presentation of results will improve the quality and value of research. The Nordic Arthroplasty Register Association (NARA) has therefore developed guidelines for the statistical analysis of arthroplasty register data. The guidelines are divided into two parts, one with an introduction and a discussion of the background to the guidelines (, see pages x-y in this issue), and this one with a more technical statistical discussion on how specific problems can be handled. This second part contains (1) recommendations for the interpretation of methods used to calculate survival, (2) recommendations on howto deal with bilateral observations, and (3) a discussion of problems and pitfalls associated with analysis of factors that influence survival or comparisons between outcomes extracted from different hospitals.
LOW LIGHT PHYTOPLANKTON GENERA OBSERVED IN THE COASTAL AND ESTUARINE WATERS OF GOA , INDIA

This is the first study carried-out to understand the phytoplankton genera in the low light (less than 50 μmol/m/s of photosynthetically available radiation) for the estuarine and coastal waters of Goa, India. There were 93 phytoplankton genera observed of which the most abundant were Skeletonema spp. , Leptocylindrus spp. , Thalassiosira spp. , Cerataulina sp. , and Fragilariopsis sp. The centric diatom Skeletonema spp. was the most abundant phytoplankton genera observed during all the seasons. Similarly, other abundant genera observed all through the year in low light in the coastal and estuarine waters were Cerataulina sp. , Chaetoceros spp. , Coscinodiscus spp. , Leptocylindrus spp. , Navicula spp. , Nitzschia spp. , Pleurosigma spp. , Pseudo-nitzschia spp. , and Thalassiosira spp. Phytoplankton observed only in estuarine waters were Bacillaria sp. , Planktoniella sp. , Biddulphia sp. , and Asterionellopsis spp. , while Enotia sp. , Oxytoxum sp. , were observed only in the coastal waters during the summer season. Contributions of chlorophyll a and fucoxanthin were relatively higher in low light regions, while the photoprotective pigment β-carotene was lower than observed at the surface. The maximum spectral light available at the low light region varied for water types, and was 537 to 581 nm in the coastal waters, while it shifted to longer wavelengths 561 to 648 in the estuarine waters.
On Carleman and observability estimates for wave equations on time‐dependent domains

We establish new Carleman estimates for the wave equation, which we then apply to derive novel observability inequalities for a general class of linear wave equations. The main features of these inequalities are that (a) they apply to a fully general class of time‐dependent domains, with timelike moving boundaries, (b) they apply to linear wave equations in any spatial dimension and with general time‐dependent lower order coefficients, and (c) they allow for smaller time‐dependent regions of observations than allowed from existing Carleman estimate methods. As a standard application, we establish exact controllability for general linear waves, again in the setting of time‐dependent domains and regions of control.

Occurrence and Prevalence of Bacterial Species as Identified from Camel Wounds

A total of 80 samples were collected from male, female and young calves of camel and tested for bacterial contamination. Twelve different bacterial species were identified from wound samples of camels. The species were Actinobacillus ligneirsi, Bacillus cereus, Citrobacter species, Corynebacterium pygenes, Escherichia coli, Klebsiella ozeanea, Pasturella pneumotropica, Pseudomonas aeroginosa, Salmonella arizona, Staphylococcus aureus, Staphylococcus epidermidis, and Staphylococcus intermedius. Out of the 80 samples studied, 46 were from males, 12 from females and 22 from young calves. The percentage prevalence of bacterial infection in open and close wounds was also demonstrated. The incidence of infection in open wounds of males, females and young calves was 83.33, 100, and 88.88%, respectively, while the incidence of infection in close wounds of the above animals was observed as 82.12, 60.00 and 84.61%, respectively. A survey on mixed infections in wound samples of camels was also carried-out during this work. The mixed infections in the samples of males, females and young calves were recorded as 76.08, 66.66 and 81.81%, respectively. Morphologically, these varied from cocci to rod shape and were gram-positive and negative. Some produced spherical, swarming, and spreading colonies while fewer produced α and β hemolytic colonies of red blood cells on blood agar. The percentage occurrence of individual bacterial species in wound samples was also investigated. The incidence of Actinobacillus ligneirsi, Bacillus cereus, Citrobacter species, Corynebacterium pygenes, Escherichia coli, Klebsiella ozeanea, Pasturella pneumotropica, Pseudomonas aeroginosa, Salmonella arizona, Staphylococcus aureus, Staphylococcus epidermidis, and Staphylococcus intermedius in wounds of camels was 4.47, 5.97, 2.98, 5.97, 17.91, 7.46, 5.97, 8.95, 5.97, 14.92, 1.49, and 17.91%, respectively.
The Classroom is a Game ?

Games have made their way into the classroom in a multitude of ways to attract and retain students. The academic community has made great strides incorporating games into academic study. Although some have suggested formal links, little work has been done on formalizing how game design can inform instructional design. We explore this avenue by showing existing overlaps between the disciplines and areas where game design and instructional design can inform each other. Examples from a series of introductory programming courses will demonstrate the connections and suggest future development.
C O ] 4 O ct 2 01 8 On the consistency of the expansion with the perturbations

Assuming a simple form for the growth index γ(z) depending on two parameters γ0 ≡ γ(z = 0) and γ1 ≡ γ ′(z = 0), we show that these parameters can be constrained using background expansion data. We explore systematically the preferred region in this parameter space. Inside General Relativity we obtain that models with a quasi-static growth index and γ1 ≈ −0.02 are favoured. We find further the lower bounds γ0 & 0.53 and γ1 & −0.15 for models inside GR. Models outside GR having the same background expansion as ΛCDM and arbitrary γ(z) with γ0 = γ ΛCDM 0 , satisfy Geff,0 > G for γ1 > γ ΛCDM 1 , and Geff,0 < G for γ1 < γ ΛCDM 1 . The first models will cross downwards the value Geff = G on very low redshifts z < 0.3, while the second models will cross upwards Geff = G in the same redshift range. This makes the realization of such modified gravity models even more problematic.
Individual Oximes Against VX in Rats and Mice A Comparison of the Reactivating and Therapeutic Efficacy of Chosen Combinations of Oximes With

The ability of 2 combinations of oximes (HI-6 þ trimedoxime and HI-6 þ K203) to reactivate VX-inhibited acetylcholinesterase and reduce acute toxicity of VX was compared with the reactivating and therapeutic efficacy of antidotal treatment involving a single oxime (HI-6, trimedoxime, K203) in rats and mice. Our results showed that the reactivating efficacy of both combinations of oximes studied in rats is significantly higher than the reactivating efficacy of all individual oximes in diaphragm and roughly corresponds to the most effective individual oxime in blood and brain. Both combinations of oximes were found to be more effective in the reduction of acute lethal toxicity of VX in mice than the antidotal treatment involving the most efficacious individual oxime although the difference is not significant. Based on the obtained data, we can conclude that the antidotal treatment involving the chosen combinations of oximes brings benefit for the reactivation of VX-inhibited acetylcholinesterase in rats and for the antidotal treatment of VX-induced acute poisoning in mice.
Capacity Allocation For Parking Choice Models Considering User Heterogeneity

Developing and implementing innovative parking policies is of high importance for authorities, in order to keep the traffic flow and accessibility of attractive destinations at a high level (Benenson and Martens, 2009). These parking issues go hand in hand with the recent upcoming of electric vehicle users. Creating an extensive charging network and supportive electric vehicle environment helps addressing the barriers to use electric cars and is thus a crucial part of the energy transition. By examining Santona, we seek to glean lessons on the steps towards efficient and innovative policy actions. We found that people differ in taste regarding the time to find a parking spot and the fee that has to be paid. The impact of the fee depends on the income level of the individual and the whether or not someone is a resident of the town. Furthermore, the age of the vehicle is key in the decision process. In this research, we conclude what where a possible underground parking facility is most appropriate. Also, we see that the on-street parking fee should not be higher than 0.7 euros. Regarding power outlets for the electric vehicles, we conclude that up to when one percent of the people use an electric car, the amount of people in queues are agreeable. However, when the amount of electric car users increases to more than that, problems arise. The results of this research can be generalized for policy-making related to parking management.
expression enhances Glypican-3 α MicroRNA-1291-mediated silencing of IRE 1 Material Supplemental

MicroRNAs (miRNA) are generally described as negative regulators of gene expression. However, some evidence suggests that they may also play positive roles. As such, we reported that miR-1291 leads to a GPC3 mRNA expression increase in hepatoma cells through a 3′ untranslated region (UTR)-dependent mechanism. In the absence of any direct interaction between miR1291 and GPC3 mRNA, we hypothesized that miR-1291 could act by silencing a negative regulator of GPC3 mRNA expression. Based on in silico predictions and experimental validation, we demonstrate herein that miR-1291 represses the expression of the mRNA encoding the endoplasmic reticulum (ER)-resident stress sensor IRE1α by interacting with a specific site located in the 5′ UTR. Moreover, we show, in vitro and in cultured cells, that IRE1α cleaves GPC3 mRNA at a 3′ UTR consensus site independently of ER stress, thereby prompting GPC3 mRNA degradation. Finally, we show that the expression of a miR-1291-resistant form of IRE1α abrogates the positive effects of miR-1291 on GPC3 mRNA expression. Collectively, our data demonstrate that miR-1291 is a biologically relevant regulator of GPC3 expression in hepatoma cells and acts through silencing of the ER stress sensor IRE1α.
Welfare and society – measured versus self-reported body height and body mass in medicine students of Wroclaw

The basic anthropometric parameters, such as body weight and body height, are the data most frequently analyzed during a physical examination. Being aware of one’s body weight and height not only allows the proper selection of material goods, HEALTH AND WELLNESS 4/2014 Wellness and society 76 but also has great significance in leading a healthy life-style, inter alia in assessing the degree of obesity. Being familiar with these basic anthropometric data is of great significance in medical sciences. It allows the stratification of the cardio-vascular risk in adults. Inappropriately high body weight is one of modifiable risk factors. The aim of the study was to assess the correct knowledge of these parameters in a group of students of the Faculty of Medicine. We analyzed a group of 88 healthy individuals, 39 women (mean age 19.97 years) and 49 men (19.87 years). We proved that participants do not know their body weight and height. A comparison of self-reported and actual data reveals statistically significant differences. The students have overestimated their body height and underestimated their body weight.The differences between BMIdekl and BMIreal calculated based on self-reported data are statistically significant. However, they carry no clinical significance.When conducting a study among medicine students, self-reported data for body weight and height are sufficient for analysis and there is no need for objective measurements.
Pathogenicity of Entomopathogenic Fungi on the Weevil of the Andes (Premnotrypes vorax Hustache) of the Potato (Solanum tuberosum L.) in Chimborazo Province, Ecuador

From thirty native isolates of entomopathogenic fungi, which were obtained from corpses of larvae and adults of Andean weevil (Premnotrypes vorax Hustache); two fungi with entomopathogenic characteristics were selected through laboratory tests, which will be used in a program of integrated management of this pest in the Ecuadorian inter-Andean region. The pathogenicity of the 30 isolates was determined by the mortality that they caused in larvae and adults and it was expressed in percentage; for this, a complete randomized design (CRD) was used. The LC50 and TL50 were determined by Probit analysis. The two selected isolates corresponded to: Metarhizium anisopliae (Metschnikoff 1879) Sorokin 1883 (A13) and Beauveria bassiana (Bals.-Criv.) Vuill. 1912 (A21), which proved to be the best, because they caused the highest mortality in larvae of the fourth instar and adults of P. vorax. The Probit analysis showed that LC50 for A21 isolate (B. bassiana) in fourth instar larvae was obtained with a concentration of 1,75x109 spores/ml and 1,08x109 spores/ml for adults. Instead for A13 isolate (M. anisopliae), the LC50 was obtained with a concentration of 1,65x109 spores/ml for larvae and 2,42x109 spores/ml for adults. The LT50 for the selected isolates at the indicated concentrations, was 4,84 and 4,32 days for larvae with A13 and A21 isolates respectively, while, for adults, the shortest time was obtained with A21 isolate in 4.36 days, compared with A13 isolate, that delayed 20,70 days. The larval stage of P. vorax was the most susceptible to A13 isolate, on the other hand, larvae and adults were equally susceptible to A21 isolate at the indicated concentrations. According to the results obtained, the two selected isolates can be used as an alternative to the use of conventional agrochemicals, which will contribute to a more ecological production.

Monocular depth estimation using learning-based approaches has become promising in recent years. However, most monocular depth estimators either need to rely on large quantities of ground truth depth data, which is extremely expensive and difficult to obtain, or predict disparity as an intermediary step using a secondary supervisory signal leading to blurring and other artefacts. Training a depth estimation model using pixel-perfect synthetic data can resolve most of these issues but introduces the problem of domain bias. This is the inability to apply a model trained on synthetic data to real-world scenarios. With advances in image style transfer and its connections with domain adaptation (Maximum Mean Discrepancy), we take advantage of style transfer and adversarial training to predict pixel perfect depth from a single real-world color image based on training over a large corpus of synthetic environment data. Experimental results indicate the efficacy of our approach compared to contemporary state-of-the-art techniques.
Pulmonary Perspective

This perspective highlights advances in the understanding of the role of cellular metabolism in the pathogenesis of pulmonary hypertension. Insights gained in the past 20 years have revealed several similarities between the cellular processes underlying the pulmonary vascular remodeling in pulmonary hypertension and those seen in cancer processes. In line with these insights, there is increasing recognition that abnormal cellular metabolism, notably of aerobic glycolysis (the “Warburg effect”), the potential involvement of hypoxia-inducible factor in this process, and alterations in mitochondrial function, are key elements in the pathogenesis of this disease. The glycolytic shift may underlie the resistance to apoptosis and increased vascular cell proliferation, which are hallmarks of pulmonary hypertension. These investigations have led to novel approaches in the diagnosis and therapy of pulmonary hypertension.
