Laboratory Evaluation of Warm Mix Asphalt Influence on Theoretical Maximum Specific Gravity
Authors: Yu Jianhua , Williams R. Christopher , Buss Ashley F. 
Published: June 2012

Abstract
Warm mix asphalt (WMA) technology provides sufficient workability for asphalt mixtures at reduced mixing and compaction temperatures. Depending on the WMA technology, the typical temperature reduction range is 20 °C to 55 °C below hot mix asphalt (HMA) production temperatures. WMA involves chemical and wax additives that are added to an asphalt binder or incorporated through the use of foaming technology. The main advantages of WMA are reduced emissions and a reduction in combustible fuel consumption. Ongoing WMA research projects have documented some differences between HMA and WMA mixes, prompting numerous research projects that are investigating these concerns. The purpose of this research is to evaluate the volumetric properties by directly comparing laboratory produced WMA and HMA mixes. This study investigates the impact of WMA additives on the volumetric properties, specifically, the theoretical maximum specific gravity (Gmm). The Gmm testing followed the procedure of ASTM D2041. Two mix designs with HMA binder were produced, one without recycled asphalt pavement (RAP) and the other with 30 % RAP. After the mix designs were completed, no additional changes were made to account for the addition of the WMA technology. The mixes included the WMA technologies Sasobit and Advera, as well as an HMA control, for a total of six different laboratory produced mixes. Each mix was produced at 120 °C, 135 °C, and 150 °C, and each mix was oven cured for 1, 2, and 4 h. The test results were analyzed using statistical principles to determine whether differences in the Gmm values were statistically significant. The results show that temperature has little impact on Gmm. Gmm was not affected by curing times of 1 and 2 h, but the longer curing time of 4 h resulted in a statistically significant increase in Gmm. Further analysis revealed that the mix sensitivity to curing time depends on the amount of RAP in the mix. For the mix designs studied, the Advera Gmm values were similar to the HMA values, but the Sasobit Gmm values were statistically lower than the Advera values.
Comparative Analysis of Brake Data of Vehicles on Two Different Ministry of Transport Brake Roller Testers

Abstract
The research described herein was carried out by the mechanical engineering staff at the mechanical laboratory of Miguel Hernández University (UMH) in Elche, Spain. This study compares the braking of a vehicle on two different Ministry of Transport (MOT) brake testers. We have analyzed mathematical formulas about braking on MOT brake testers, and we indicate which factors could have a theoretical influence in braking on a rolling road. If the tire pressure is varied, false results might be obtained from the brake tester, meaning that if tires are inflated at a low pressure, the vehicle will not pass the MOT brake test even if the brakes are in good condition. Conversely, if the brakes are in bad condition but the tire pressure is higher than that recommended by the manufacturer, a false passing rating might be produced. This article attempts to show that the MOT brake testing equipment is often wrong and inexact, and it provides data and graphs to prove that tire pressure can be a determining factor when assessing the condition of brakes. We also study the influence of the wheel base between rollers in brake and slip data measurements. A car is placed on a bank of rollers with the handbrake released; the rollers then move at a constant speed of 5 km/h, and the brake pedal is depressed until 100 % slippage is obtained. A velocity of 5 km/h is sufficient to obtain 100 % slippage. The pressure in the hydraulic brake circuit on the right front wheel of the vehicle is also measured with a hydraulic sensor in the hydraulic pipe of the right front wheel. We can obtain the slippage by measuring the angular velocity of the wheel and the roller. The angular velocity is determined by two encoders, the first fitted on the brake roller tester and the second on the wheel of the vehicle. At UMH we have one MOT brake roller tester with a 450 mm distance between each roller where we have measured brake and slip. We also compare the results with those from another MOT station at which the roller tester has only 410 mm between the rollers and analyze the difference. This article demonstrates that the MOT brake and slide data results depend on the distance between rollers, the tire type, and the pneumatic pressure. Data and graphs are provided to substantiate the findings.

Published: June 2012

OBJECTIVE:
We evaluated the hypothesis that later start of stimulant treatment of attention-deficit/hyperactivity disorder adversely affects academic progress in mathematics and language arts among 9- to 12-year-old children.

METHODS:
We linked nationwide data from the Icelandic Medicines Registry and the Database of National Scholastic Examinations. The study population comprised 11 872 children born in 1994–1996 who took standardized tests in both fourth and seventh grade. We estimated the probability of academic decline (drop of ≥5.0 percentile points) according to drug exposure and timing of treatment start between examinations. To limit confounding by indication, we concentrated on children who started treatment either early or later, but at some point between fourth-grade and seventh-grade standardized tests.

RESULTS:
In contrast with nonmedicated children, children starting stimulant treatment between their fourth- and seventh-grade tests were more likely to decline in test performance. The crude probability of academic decline was 72.9% in mathematics and 42.9% in language arts for children with a treatment start 25 to 36 months after the fourth-grade test. Compared with those starting treatment earlier (≤12 months after tests), the multivariable adjusted risk ratio (RR) for decline was 1.7 (95% confidence interval [CI]: 1.2–2.4) in mathematics and 1.1 (95% CI: 0.7–1.8) in language arts. The adjusted RR of mathematics decline with later treatment was higher among girls (RR, 2.7; 95% CI: 1.2–6.0) than boys (RR, 1.4; 95% CI: 0.9–2.0).

CONCLUSIONS:
Later start of stimulant drug treatment of attention-deficit/hyperactivity disorder is associated with academic decline in mathematics.
Effects of ocular administration of ophthalmic 2% dorzolamide hydrochloride solution on aqueous humor flow rate and intraocular pressure in clinically normal cats
Authors: Rankin Amy J. , Crumley William R. , Allbaugh Rachel A. 
Published: June 2012

Abstract
Objective—To determine the effects of ocular administration of ophthalmic 2% dorzolamide hydrochloride solution on aqueous humor flow rate (AHFR) and intraocular pressure (IOP) in clinically normal cats.
Animals—20 clinically normal domestic shorthair cats.
Procedures—Following an acclimation period, IOP was measured in each eye of all cats 5 times daily for 3 days to determine baseline values. Fifteen cats received 1 drop of 2% dorzolamide solution and 5 cats received 1 drop of control solution in each eye every 8 hours for 5 days (treatment phase). The IOP of each eye was measured 5 times during each day of the treatment phase. Prior to and after the treatment phase, AHFR in both eyes of each cat was measured via fluorophotometry.
Results—Prior to treatment, AHFR or IOP did not differ between the treatment and control groups. In dorzolamide-treated cats, mean AHFR after the treatment phase (3.47 ± 1.5 μL/min) was significantly lower than the value prior to treatment (5.90 ± 2.2 μL/min) and mean IOP during the treatment phase (11.1 ± 1.0 mm Hg) was significantly lower than the baseline mean IOP (14.9 ± 1.0 mm Hg). In the control group, IOP values did not differ before or during the treatment phase and AHFRs did not differ before and after the treatment phase.
Conclusions and Clinical Relevance—Ocular administration of 2% dorzolamide solution significantly decreased AHFR and IOP in clinically normal cats. Application of 2% dorzolamide solution may be an effective treatment in cats with glaucoma.
The degenerate C. Neumann system I: symmetry reduction and convexity
Authors: Dullin Holger , Hanßmann Heinz 
Published: June 2012

Abstract
The C. Neumann system describes a particle on the sphere S
n under the influence of a potential that is a quadratic form. We study the case that the quadratic form has ℓ +1 distinct eigenvalues with multiplicity. Each group of m
σ equal eigenvalues gives rise to an O(m
σ)-symmetry in configuration space. The combined symmetry group G is a direct product of ℓ + 1 such factors, and its cotangent lift has an Ad*-equivariant momentum mapping. Regular reduction leads to the Rosochatius system on S
ℓ, which has the same form as the Neumann system albeit for an additional effective potential.
To understand how the reduced systems fit together we use singular reduction to construct an embedding of the reduced Poisson space T*S
n/G into ℝ3ℓ+3. The global geometry is described, in particular the bundle structure that appears as a result of the superintegrability of the system. We show how the reduced Neumann system separates in elliptical-spherical co-ordinates. We derive the action variables and frequencies as complete hyperelliptic integrals of genus ℓ. Finally we prove a convexity result for the image of the Casimir mapping restricted to the energy surface.

Abstract
Testicular cancer is rare but is the most common cancer in males between 15 and 34 years of age. Two principal types of testicular cancer are distinguished: seminomas and non-seminomas. If detected early, the overall cure rate for testicular cancer exceeds 90%. In this study, artificial neural network (ANN) analysis as a prognostic tool was demonstrated regard to five year recurrence after the non-seminoma treatment. Data from 202 patients treated for non-seminoma were available for evaluation and comparison. A total of 32 variables were analysed using the ANN. The ANN approach, as an advanced multivariate data processing method, was demon-strated to provide objective prognostic data. Some of these prognostic factors are consistent or even imperceptible with previously evaluated by other statistical methods.

Published: June 2012

Abstract
The aim of the present study was to investigate asymmetric (ADMA) and symmetric dimethylarginine (SDMA) production in patients presenting with one or more risk factor (RF) for coronary heart disease (CHD). Patients and methods: Overall, 113 participants were enrolled in the study, including 45 patients presenting with risk for CHD (27 male and 18 female; aged 55.9 ± 6.4 years), 30 sex and age-matched middle-aged healthy controls (16 male and 14 female; aged 56.3 ± 8.4 years), and 38 young healthy controls (38 male; aged 24.6 ± 3.9 years). Results: No significant differences for ADMA and SDMA were recorded between patients groups presenting with risk for CHD. However, ADMA and SDMA were significantly higher in all examined patient groups (≥3 and 1–2 RF, hypertensive and non-hypertensive, obese and non-obese, diabetics and non-diabetics) compared with both control groups (middle-aged and young controls) (p<0.001). ADMA significantly correlated with SDMA in ≥3 RF (p<0.05), hypertensive (p<0.05), non-obese (p<0.05), non-diabetics (p<0.01), as well in middle-aged (p<0.05) and young controls (p<0.001). Conclusion: Significantly higher ADMA and SDMA were found between patients presenting with risk for CHD (≥3 and 1–2 RF, hypertensive and nonhypertensive, obese and non-obese, diabetics and non-diabetics) and healthy, middle-aged and young controls. ADMA significantly correlated with SDMA in ≥3 RF, hypertensive, non-obese and non-diabetic patients, as well as in middle-aged and young controls.
Tuber donnagotto, a new winter truffle species from Istria, Croatia
Authors: Božac Romano , Širić Ivan 
Published: June 2012

Abstract
- Tuber donnagotto is a new winter black truffle belonging to the order Pezizales and the family Tuberaceae. It grows in winter in the calcareous gravel soil (pH 7.6-7.8) near the Adriatic Sea (Rovinj, Istria, Croatia) in predominantly pine forests (Pinus halepensis). Although similar to other black truffles, it has very irregular and hard fruit bodies, lobate and knotted in form, with deep irregular cavities reaching the middle of the fruit bodies. These cavities are clearly evident in the cross-section of the fruit bodies. Adistinctive characteristic of this truffle is the fact that when it is hermetically closed it can be kept in a refrigerator (2-4 °C) for more than 60 days. Tuber donnagotto has a slight but pleasant odor, reminiscent of boletus (Boletus reticulates, B. edulis). Furthermore, T. donnagotto has yellow-brownish and reticulate-alveolate spores, measuring 20-30 × 20-25 mm.
Sensitivity experiments for the Antarctic ice sheet with varied sub-ice-shelf melting rates
Authors: Sato Tatsuru , Greve Ralf 
Published: June 2012

AbstractIce-sheet modelling is an important tool for predicting the possible response of ice sheets to climate change in the past and future. An established ice-sheet model is SICOPOLIS (SImulation COde for POLythermal Ice Sheets), and for this study the previously grounded-ice-only model was complemented by an ice-shelf module. The new version of SICOPOLIS is applied to the Antarctic ice sheet, driven by standard forcings defined by the SeaRISE (Sea-level Response to Ice Sheet Evolution) community effort. A crucial point for simulations into the future is to obtain reasonable initial conditions by a palaeoclimatic spin-up, which we carry out over 125 000 years from the Eemian until today. We then carry out a set of experiments for 500 years into the future, in which the surface temperature and precipitation are kept at their present-day distributions, while sub-ice-shelf melting rates between 0 and 200 ma–1 are applied. These simulations show a significant, but not catastrophic, sensitivity of the ice sheet. Grounded-ice volumes decrease with increasing melting rates, and the spread of the results from the zero to the maximum melting case is ~0.65ms.l.e. (metres sea-level equivalent) after 100 years and ~2.25ms.l.e. after 500 years.
Sur l'industrialisation contemporaine de l'hédonisme
Authors: Michaud Yves 
Published: June 2012

Résumé L’article donne tout d’abord quelques pistes historiques sur la notion de plaisir, depuis l’hédonisme antique jusqu’à nos jours. Ce n’est qu’au dix-neuvième siècle que les progrès de la médecine rendent possible de nouvelles attitudes vis-à-vis de l’hédonisme : une éthique du bonheur commandé et contrôlé, qui se prolonge et surtout peut être recherché et produit à volonté ou presque. Aujourd’hui, l’évolution s’est poursuivie, s’est accélérée, et les moyens du plaisir se sont perfectionnés. Ce qui donne à l’hédonisme encore de nouveaux visages : l’expérience sensorielle et corporelle, la détente et le relâchement, et le bien-être.
L'industrialisation de l'hédonisme. Nouveaux cultes du corps : de la production de soi à la perfectibilité addictive
Authors: Queval Isabelle 
Published: June 2012

Résumé Le XXI e siècle confirme une révolution : depuis quelques décennies, la perfectibilité du corps se concrétise par la mise en œuvre de moyens médicaux et techniques sans précédent. Ce n’est pas simplement l’espérance de vie qui s’est accrue dans les pays industrialisés, c’est aussi la capacité à vivre durablement dans un corps moins souffrant. Se forme la volonté, ou le fantasme, d’une production du corps. Médicalisation de la naissance, prévention de l’hygiène publique, pharmacologie, cosmétologie, chirurgie, culte de l’« entretien de soi » croisent des attentes collectives et individuelles, jusqu’aux frontières de l’irrationnel ou de l’eugénisme – obtenir un corps ou un enfant « parfait » –, de l’addiction – à l’effort physique, à la chirurgie esthétique, aux substances dopantes – et jusqu’aux questionnements éthiques portant sur le contrôle. Le corps est donc l’objet d’une instrumentalisation ambivalente. Certes, il est un « corps pour jouir », la beauté, la jeunesse, la santé elle-même sont les gages d’un nouveau narcissisme et d’une intégration sociale supposée. Mais le « désir de bien faire » anime aussi cette dynamique, quand le médecin devient le nouveau moraliste, celui qui dit la vie bonne, quand la vacuité des idéaux pour le citoyen des sociétés démocratiques avancées laisse place à une rationalité instrumentale qui peut devenir destructive, privilégiant les moyens sur la fin. Ainsi, la perfectibilité devient-elle une obsession, une addiction qui se mêle à d’autres. Ainsi, le plaisir recherché dépend-il de temporalités croisées, celle de l’immédiateté et celle d’une projection incessamment travaillée vers le futur.
Les addictions, la science et les approches de sens
Authors: Valleur Marc 
Published: June 2012

Résumé Autour des questions d’addiction se cristallisent des difficultés épistémologiques considérables – notamment en ce qui concerne le statut des addictions sans drogue. L’opposition du « bio » et du « psycho », des sciences de la vie aux sciences humaines et sociales, est omniprésente dans ce champ, de façon peut-être plus visible que dans celui de la psychiatrie, qui est traversé de ces divisions depuis sa naissance. L’appel fréquent à des approches intégrées, bio-psycho-sociales, comme l’adhésion générale à un refus du dualisme cartésien du corps et de l’âme, ne doit pas faire sous-estimer les difficultés de l’entreprise : il ne s’agit pas seulement de décider si les addictions sont ou non de « vraies » maladies, attestées en tant que telles par la mise en évidence d’un « facteur X » biologique. À l’incertitude du statut de l’objet addiction s’ajoute en effet le choix du regard, de l’abord de cet objet : les approches scientifiques et les approches « de sens », toutes légitimes, ne sont pas « commensurables », les critères des unes ne pouvant ni valider ni invalider les autres. « Bricolant » des modèles improbables mêlant les deux mondes, le clinicien se trouve, de fait, dans une situation de dualisme méthodologique – et non ontologique – qu’il vaut mieux assumer qu’ignorer.
Modernité vaporeuse et imagination détruisante
Authors: Kim Hong Jung 
Published: June 2012

Résumé Cet article a pour but d’analyser le régime scopique fondé sur l’imagination détruisante, dont les deux manifestations intéressantes se trouvent dans la représentation des nuages chez Baudelaire et chez les impressionnistes. Par le concept de régime scopique, j’entends la manière dont l’œil de l’artiste « artialise » le monde en paysage. Les deux pôles principaux constituant le régime scopique sont l’œil et le paysage qui se mettent en relation réciproque (artialisation et subjectivation). Le travail s’articule en deux temps. J’analyse, dans un premier temps, l’invention du paysage vaporeux dont la figure centrale est le nuage chez Baudelaire et chez les impressionnistes. Ensuite, j’examine l’invention de l’œil réveillé correspondant à l’imagination détruisante qui à l’opposé de l’ Einbildungskraft kantienne exerce son pouvoir négatif de destruction.
Internet et la mort symbolique
Authors: Xu Yi Bing 
Published: June 2012

Résumé L’objectif de cet article réside dans la découverte de la « vérité » d’Internet. À partir de son observation pratique en tant qu’ingénieur en télécommunications et de sa réflexion philosophique sur Internet, l’auteur étudie ce médium d’un point de vue sociologique. Par là, Internet n’est plus « neutre », il possède une certaine représentation de la mort – l’auteur dit que c’est une mort symbolique. Après avoir analysé la mort, l’auteur croit que toutes les « réalités » sur la mort sont symboliques. La question se pose : comment faire face à cette mort symbolique d’Internet ? L’auteur propose, comme le dit J. Baudrillard, de « prendre la mort contre la mort ».

On the Average Number of Square-Free Values of Polynomials
Authors: Shparlinski Igor E. 
Published: June 2012

Abstract.We obtain an asymptotic formula for the number of square-free integers in N consecutive values of polynomials on average over integral polynomials of degree at most k and of height at most H, where H ≥ Nk-1+ε for some fixed ε > 0. Individual results of this kind for polynomials of degree k > 3, due to A. Granville (1998), are only known under the ABC-conjecture.
Work-Life Factors and Cardiovascular Disease in Paediatric Occupational Therapists
Authors: Poulsen Anne , Khan Asad , Meredith Pamela , Henderson Julie , Castrisos Veronica 
Published: June 2012

Introduction: With cardiovascular disease (CVD) increasing for female workers, there is a need to understand the factors associated with CVD in members of the occupational therapy, predominantly female, profession. The association between burnout and physical health effects, such as CVD, has not been investigated in paediatric occupational therapists. Method: Associations between CVD and demographic and work-life factors were investigated in a nationwide postal survey of 486 paediatric occupational therapists. Results: The prevalence of CVD in the study population was 11.02%. Private practitioners, older therapists and those with additional self-reported health problems from respiratory disease had increased odds of reporting CVD. In contrast, lower odds of CVD were found for therapists with access to social support, a secure attachment style and income satisfaction. Conclusion: Understanding demographic, personal and work-related variables associated with CVD in paediatric occupational therapists provides valuable information about members of the profession. The identification of potentially modifiable work-life factors that are inversely associated with CVD, such as social support and having a secure attachment style, suggests further avenues for research and intervention. Ongoing vigilance, and education directed towards self-care as well as client care, is required to ensure optimal health for colleagues.
