Pressure Stimulated Currents (PSC)in marble samples

The electrical behaviour of marble samples from Penteli Mountain was studied while they were subjected to uni- axial stress. The application of consecutive impulsive variations of uniaxial stress to thirty connatural samples produced Pressure Stimulated Currents (PSC). The linear relationship between the recorded PSC and the applied variation rate was investigated. The main results are the following: as far as the samples were under pressure cor- responding to their elastic region, the maximum PSC value obeyed a linear law with respect to pressure varia- tion. In the plastic region deviations were observed which were due to variations of Young's modulus. Further- more, a special burst form of PSC recordings during failure is presented. The latter is emitted when irregular lon- gitudinal splitting is observed during failure.
Structural and doping effects in the half-metallic double perovskite A 2 CrWO 6 (A=Sr, Ba, and Ca)

The structural, transport, magnetic, and optical properties of the double perovskite A2CrWO6 with A = Sr,Ba,Ca have been studied. By varying the alkaline earth ion on the A site, the influence of steric effects on the Curie temperature TC and the saturation magnetization has been determined. A maximum TC = 458 K was found for Sr2CrWO6 having an almost undistorted perovskite structure with a tolerance factor f~1. For Ca2CrWO6 and Ba2CrWO6 structural changes result in a strong reduction of TC. Our study strongly suggests that for the double perovskites in general an optimum TC is achieved only for f~1, that is, for an undistorted perovskite structure. Electron doping in Sr2CrWO6 by a partial substitution of Sr2+ by La3+ was found to reduce both TC and the saturation magnetization Ms. The reduction of Ms could be attributed both to band structure effects and the Cr/W antisites induced by doping. Band structure calculations for Sr2CrWO6 predict an energy gap in the spin-up band, but a finite density of states for the spin-down band. The predictions of the band structure calculation are consistent with our optical measurements. Our experimental results support the presence of a kinetic energy driven mechanism in A2CrWO6, where ferromagnetism is stabilized by a hybridization of states of the nonmagnetic W site positioned in between the high spin Cr sites.
The morphology of the expanding ejecta of V2491 Cygni (2008 N.2)

Determining the evolution of the ejecta morphology of novae provides valuable information on the shaping mechanisms in operation at early stages of the nova outburst. Understanding such mechanisms has implications for studies of shaping for example in proto-Planetary Nebulae. Here we perform morpho-kinematical studies of V2491 Cyg using spectral data to determine the likely structure of the ejecta and its relatio nship to the central system and shaping mechanisms. We useshape to model different morphologies and retrieve their spectra. These synthetic spectra are compared with observed spectra to determine the most likely morphology giving rise to them, including system inclination and expansion velocity of the nova ejecta. We find the best fit remnant morphology to be that of pol ar blobs and an equatorial ring with an implied inclination of 80 +3 −12 degrees and an maximum expansion velocity of the polar blobs of 3100 +200 −100 km s −1 and for the equatorial ring 2700 +200 −100 km s −1 . This inclination would suggest that we should observe eclipses which will enable us to determine more precisely important parameters of the central binary. We also note that the amplitude of the outburst is more akin to the found in recurrent nova systems.
SEISMIC DISCRIMINATION OF THERMAL AND MAGNETIC ANOMALIES IN SUNSPOT UMBRAE

Efforts to model sunspots based on helioseismic signatures need to discriminate between the effects of (1) a strong magnetic field that introduces time-irreversible, vantage-dependent phase shifts, apparently connected to fast- and slow-mode coupling and wave absorption and (2) a thermal anomaly that includes cool gas extending an indefinite depth beneath the photosphere. Helioseismic observations of sunspots show travel times considerably reduced with respect to equivalent quiet-Sun signatures. Simulations by Moradi & Cally of waves skipping across sunspots with photospheric magnetic fields of order 3 kG show travel times that respond strongly to the magnetic field and relatively weakly to the thermal anomaly by itself. We note that waves propagating vertically in a vertical magnetic field are relatively insensitive to the magnetic field, while remaining highly responsive to the attendant thermal anomaly. Travel-time measurements for waves with large skip distances into the centers of axially symmetric sunspots are therefore a crucial resource for discrimination of the thermal anomaly beneath sunspot umbrae from the magnetic anomaly. One-dimensional models of sunspot umbrae based on compressible–radiative–magnetic-convective simulations such as by Rempel et al. can be fashioned to fit observed helioseismic travel-time spectra in the centers of sunspot umbrae. These models are based on cooling of the upper 2–4 Mm of the umbral subphotosphere with no significant anomaly beneath 4.5 Mm. The travel-time reductions characteristic of these models are primarily a consequence of a Wilson depression resulting from a strong downward buoyancy of the cooled umbral medium.
The problem of European freshwater populations of Gammarus duebeni Liljeborg, 1852

In addition to the well-known freshwater occurrence of Gammarus duebeni in the inland of Ireland, a similar inland occurrence in the western part of Brittany (= Bretagne, France) is demonstrated. In Brittany, as in Ireland, G. duebeni occurs in waters with low sodium concentrations (often less than 23 mg/l), whereas elsewhere in its range, G. duebeni lives in waters with a raised sodium content (either in mixohaline waters, or in “fresh” waters loaded with salts through gales from sea). Reid has proposed the designation G. duebeni α for the Irish freshwater form, G. duebeni s for the brackish water form. The subdivision of G. duebeni is strongly reinforced by the findings of Sutcliffe et al., indicating physiological differences between the α and s form. In the present paper, it is shown that significant morphometrical differences exist between the two forms, especially in the length/width ratio of the merus of the fifth leg. A mathematical test, the coefficient of difference, for this character shows it is around or above the standard of subspecific difference. On the other hand, all possible crosses between limnic animals from Eire and Brittany, and mixohaline animals from northern France and Holland, proved to be fertile. The available evidence (spatial isolation through different habitat, important physiological and morphological differences, interfertility) points very obviously in the direction of two different subspecies: the one, the nominate subspecies, living in waters with rised ion concentrations (restricted neotype locality, supralittoral rockpools at Stora Kalsoy, near Bergen, Norway); the other, celticus Stock & Pinkster, 1970, living in waters with low ion — in particular sodium — concentrations (type locality Lough Corrib, Eire). A detailed examination of the distribution pattern of G. duebeni celticus, and competing gammarids like G. pulex and Echinogammarus berilloni, in the inland of Brittany (Bretagne), makes it probable, that G. duebeni was the oldest freshwater species in that area (presumably originating from mixohaline or marine ancestors in one of the earlier interglacial periods), and that G. pulex and E. berilloni were later, postglacial, invaders in that part of Europe.
A genetic analysis reveals low prevalence of phytoplasma infection in Hyalesthes obsoletus Signoret, vector of 'bois noir', in SW-Germany

: Bois Noir is a grapevine disease responsible for severe economic losses in wine production. Bois Noir is caused by Candidatus Phytoplasma solani, cell wall-less bacteria belonging to the taxonomic group 16Sr-XII-A. In Germany, they are known to be vectored from plant to plant by the cixiid Hyalesthes obsoletus , but so far the prevalence of the disease in the vector population, as well as its spatio-temporal distribution is poorly understood. We therefore analyzed infections of H. obsoletus collected in different vineyards in Baden (South-Western Germany) with quantitative real-time PCR. From 125 analyzed individuals, only five were 30 infected with Ca . Phytoplasma solani. All infected individuals were colonized by

Independent Contributions of Upper Extremity Variables in Free Throw Shooting Accuracy from Multiple Positions: a Pilot Study in College Basketball Players

Original Article Physical factors play an important role in basketball free throw shooting success. This study aims to analyze the factors associated with success when shooting from different positions. Twenty-four college basketball players were assessed for upper extremity length, muscle strength, vertical jump height and reaction time, and hand reaction time. Five shooting positions (A–E) were located 4.54 m from the basket at angles of 45 around a semicircle. Shooting success was recorded as a percentage. The relationships between variables were analyzed with Pearson correlation analysis, and multiple linear regression analysis was performed to determine the contributions of the assessed physical factors to shooting success. The following factors contributed to the success rate: hand length, left palmar grip strength and left hand reaction time from A; left palmar grip strength, left shoulder extensor strength and vertical jump reaction time from B; left elbow extensor strength and left hand reaction time from C; right wrist extensor strength, body mass index, left shoulder external rotator strength, and left hand reaction time from D; and forearm length, left elbow extensor strength, and left wrist extensor strength from E position. Left elbow extensor strength, left hand reaction time, and vertical jump reaction time contributed to the total free throw success rate. These results of this pilot study demonstrated the important relationships between upper extremity extensor strength, grip strength, vertical jump reaction time, hand reaction time, and free throw success.

Measurement of sin 2 θ lepteff using e þ e − pairs from γ (cid:2) = Z bosons produced in p p collisions at a center-of-momentum energy of 1.96 TeV

At the Fermilab Tevatron proton-antiproton ( p ¯ p ) collider, Drell-Yan lepton pairs are produced in the process p ¯ p → e þ e − þ X through an intermediate γ (cid:2) =Z boson. The forward-backward asymmetry in the polar-angle distribution of the e − as a function of the e þ e − -pair mass is used to obtain sin 2 θ lepteff , the effective leptonic determination of the electroweak-mixing parameter sin 2 θ W . The measurement sample, recorded by the Collider Detector at Fermilab (CDF), corresponds to 9 . 4 fb − 1 of integrated luminosity from p ¯ p collisions at a center-of-momentum energy of 1.96 TeV, and is the full CDF Run II data set. The value of sin 2 θ lepteff is found to be 0 . 23248 (cid:3) 0 . 00053 . The combination with the previous CDF measurement based * Deceased. on μ þ μ − pairs yields sin 2 θ lepteff ¼ 0 . 23221 (cid:3) 0 . 00046 . This result, when interpreted within the specified context of the standard model assuming sin 2 θ W ¼ 1 − M 2 W =M 2 Z and that the W - and Z -boson masses are on-shell, yields sin 2 θ W ¼ 0 . 22400 (cid:3) 0 . 00045 , or equivalently a W -boson mass of 80 . 328 (cid:3) 0 . 024 GeV =c 2 .
Investigation of effective treatment techniques for Olive mill wastewater

Selection of cost-effective treatment modules for high saline wastewater produced from the olive mill is a challenging task. The aim of this study is to select the most effective technology applied to treat Olive mill wastewater. Several trials using various techniques were carried out to treat wastewater produced from pickling olives and olive oil manufacturing; for instance, anaerobic-aerobic, coagulation/flocculation, and electrocoagulation. The characteristics of olive manufacturing raw wastewater in terms of total dissolved solids (TDS), chemical oxygen demand (COD) and oil and grease were 10032, 9174, and 914.8 mg/l respectively. The results showed that electro-coagulation technique with aluminum electrodes and operating parameters of 30 voltage and 1.5 hours achieved COD removal rate 84%. However, the residual concentration (900 mgO2/l) still needs further treatment. Aerobic treatment using activated sludge was applied after electrocoagulation. The results showed that the use aerobic treatment after electrocoagulation is more efficient than the use of anaerobic. Analysis of the treated water showed that the maximum COD removal efficiencies were 98% at optimum conditions. The effluent quality meets the discharge regulatory standard. Consequently, the electrocoagulation followed by aerobic process can be considered as a reliable, safe and cost-effective method for the treatment of olive mill wastewater.
Mechanical characterization and modeling of prosthetic meshes

The present thesis is aimed at a mechanical characterization and at a model formulation for prosthetic meshes considering different length scales. The main focus is on providing methodologies, experimental and theoretical, to evaluate aspects of the meshes’ mechanical biocompatibility. Prosthetic meshes are synthetic network fabrics. They are implanted for soft body tissue support, such as in case of pelvic organ prolapse (POP). POP describes a descensus of the pelvic organs, herniating into the vagina. So far, the pathogenesis of POP is not fully understood as it involves a complex interplay between tissues and structures at different pelvic floor length scales. Surgical techniques for POP repair include native tissue repair and mesh repair. The major objective is to reconstruct the pelvic floor anatomy and relieve the associated symptoms in order to increase the patients’ quality of life. Due to a simplified FDA approval for these devices in the past, originating from the remarkable success of meshes in hernia repair, there is a large variety of mesh types and precut mesh kits on the market. However, recently the FDA issued a health notification warning of severe complications associated with the transvaginal placement of surgical meshes. Professional societies, such as the IUGA pleaded for a more thoughtful clinical introduction of novel implants. The need for a standardized and comprehensive product description for meshes, also including their mechanical properties was emphasized. There are theoretical and clinical indications that optimized mechanical properties of meshes will lead to an improved mechanical biocompatibility and ultimately will affect the clinical outcome of the treatment. This thesis is intended to contribute to the development of experimental techniques and protocols to assess the mechanical properties of pelvic floor tissues and prosthetic meshes in a physiologically relevant way. The notion “mechanical biocompatibility” should be sharpened by including different mechanical phenomena at different length scales and a model description to deduce respective criteria, which should be considered for clincial applications and mesh design optimization. These objectives were realized through different studies. A clinical study was conducted using the aspiration technique, an in vivo technique, to characterize the mechanical behavior of the anterior vaginal wall in women with different
Metodologia modelu proporcjonalnego ryzyka Cox’a

Prosty model regresji zakłada, że wynik (np. przeżycie lub odpowiedź na leczenie onkologiczne) może być wyjaśniony zasadniczo w oparciu o jedną zmienną objaśniającą lub predykcyjną. Podstawą tego założenia jest stwierdzenie, że wiele innych czynników, mogących mieć wpływ na wynik, ma osobno niewielkie znaczenie, a ich sumaryczny wpływ jest równy zero. To założenie jest bardzo rzadko spełnione dla czynników prognostycznych, mogących mieć wpływ na przeżycia onkologiczne i z tego powodu konieczne jest zastosowanie złożonych modeli regresji. Cox [1] opracował tego typu model dla tabeli przeżyć (zobacz także pracę Breslow’a [2]), który umożliwia analizę wpływu czynników prognostycznych na przeżycie. Autor zilustrował zastosowanie modelu dla przypadku leukemii, ale model może być stosowany do obliczania przeżyć w odniesieniu do wszystkich innych chorób, jak w przypadku przeżyć w chorobach nowotworowych lub kardiologicznych po transplantacji serca lub zawałach serca [3]. W wyniku analizy wielowymiarowej otrzymujemy zbiór czynników z określoną miarą wpływu na wynik dla każdego czynnika osobno, przy założeniu stałości pozostałych. Model Cox’a jest bardzo często stosowany i jest oferowany przez większość komercyjnych pakietów statystycznych, chociaż na ogół bez szczegółowego wyjaśnienia jego funkcjonowania. Pomimo, że model ten jest najbardziej rozpowszechniony w onkologii, istnieją w tej dziedzinie inne modele wielowymiarowe, jak np. : model log-logitowy [4, 5], czy liniowy model logitowy [6]. W dalszej części zostały one zastosowane do analizy case-control [7]. Metodologia modelu proporcjonalnego ryzyka Cox’a
Proposal to the ISOLDE and Neutron Time-of-Flight Committee 33 S ( n , α ) 30 Si cross section measurement at n _ TOF EAR 2

This proposal is a continuation and a consequence of the successful experiment performed in 2012 at n_TOF EAR1 (CERN-INTC-2012-006/INTC-P-322) in the light of the results obtained in the data analysis. The main goal of our experiment at EAR-1 was to clarify the discrepancy in the resonance region between the scarce experiment data. For this reason we took advantage of the high-energy resolution available at EAR-1 and we measured the S(n,α)Si cross-section with B(n,α)Li as reference. We have found a good agreement with Wagemans et al. Moreover, we have also obtained data below 10 keV (down to 1 eV), in a region where no previous data were known (except the thermal point), but these are not conclusive. Some effects might influence our data below 10 keV, in particular a high general electronic noise level in addition to an electronic noise signal induced by the PS accelerator signal. Furthermore, the background study was not optimized by a measurement without target for all detectors. In this situation, the extrapolation of EAR-1 data from 10 keV to thermal neutron energy is highly uncertain, and would lead to values at the thermal point more than two orders of magnitude higher with respect to the reported values. We propose to complete the measurement of the S(n,α)Si cross-section in EAR-2. The work performed during the EAR-2 commissioning on the detectors should improve the quality of the data below 10 keV hopefully providing a reliable shape and value of the S(n,α)Si cross-section below 10 keV. We will take advantage of the improved signal-to-noise ratio, a better background characterization and, especially, the much higher flux of low energy neutrons in EAR-2, as compared with EAR-1. In addition the same digitizers of the data acquisition system allow reaching the thermal neutron energy directly without the need for extrapolation This data might be relevant for applications to medical physics, also the proposed setup will allow studying nuclear structure effects related to the anisotropy in the forward and backward alpha emission suggested by Wiechers et al. Requested protons: 2·10 protons on target. Experimental area: EAR-2
Breast lesion detection using diffuse optical imaging

Diffuse optical imaging is een beeldvormende techniek waarbij dieper gelegen weefsels zichtbaar worden gemaakt met behulp van licht. De techniek wordt onder andere gebruikt bij het opsporen van borstkanker. Borsttumoren kunnen dan optisch gelokaliseerd worden door te kijken naar verhoogde absorptie en verstrooiing van licht in tumorweefsel, wat veroorzaakt wordt door lokale verschillen in hemoglobine- en waterconcentraties. Een probleem is vaak dat de resolutie van de beelden vrij laag is. Bovendien zijn afwijkingen in de borst soms minder goed waarneembaar door het relatief geringe contrast tussen tumorweefsel en gewone klieren. Anais Leproux onderzocht verschillende manieren om de beeldvorming van borstweefsel te verbeteren om zo borstkanker sneller en beter op te kunnen sporen.
