Global Magnetorotational Instability with Inflow. II. The Nonlinear Development of Axisymmetric Wall Modes

We investigate numerically the global, nonlinear behavior of magnetorotational instabilities in accretion disks by considering our previously formulated model of a cylindrical, dissipative disk with permeable boundaries. We extend the linear theory to follow the development of unstable, axisymmetric, magnetorotational modes into the nonlinear regime to determine the saturation mechanism. In each case parameters are chosen so that the most unstable mode is localized close to the inner boundary. We conduct an extensive parameter survey and find that the nonlinear behavior is mediated by the formation of a coherent radial jet that transports vertical magnetic flux within the disk. The mechanism for saturation depends critically on the strength of this jet. Different scenarios for saturation are explored in detail. The instability can either saturate in a nonlinear steady or oscillatory, non-Keplerian state, or relax back to a Keplerian state via the removal of flux from the disk by the jet.
Long-term seasonal nutrient limiting patterns at Meiliang Bay in a large, shallow and subtropical Lake Taihu, China

Lake Taihu has undergone severe eutrophication in the past three decades, and harmful cyanobacteria blooms occur nearly every year in Meiliang Bay at the north end of the lake. To elucidate the potential relationship between seasonal nutrient limitation and phytoplankton proliferation, a 20-year (1992-2011) time series of nutrient limitation in Meiliang Bay was analysed for deviations between trophic state index (TSI) parameters. Results showed that patterns of nutrient limitation in Meiliang Bay were distinctly seasonal, where phytoplankton growth was generally phosphorus (P)-limited in winter and spring, but nitrogen (N)-limited mainly occurred in summer and fall. This general pattern, however, shifted into N limitation across the four seasons during the mid-1990s because a rapid increase in industrialization led to a significant rise in the input of N and P from inflowing tributaries. The initial patterns were restored by environmental regulation in the end of 1990s, including the Zero Actions plan. Using routine monitoring data, a generalised additive model (GAM) with time and deviations between trophic state indexes for nitrogen and phosphorus (TSIN-TSIP) as explanatory variables was used to explore which nutrient was responsible for limitation of phytoplankton chlorophyll-a (Chl-a) in different seasons. Surprisingly, the model revealed a weak N limitation (TSIN-TSIP=-10) corresponded to peak values of Chl-a in summer-autumn season, which is probably because the phytoplankton community is co-limited by N and P during the period. The shift of nutrition limitation during winter-spring would partially explain high values of Chl-a throughout 1996. This study suggests that seasonal patterns of nutrient limitation must be considered to develop effective management measures to control cyanobacterial blooms.
ORIGINAL ARTICLE Comparison of Attitudes in Normal and Addicts Internet users' towards values in Teens and Youths

Concerns regarding the use of Internet technology influences that affect the human body and mind caused that sociologists, psychologists and parents in many countries feared the development of a new addiction called "Internet addiction". However, the question is that based on the rapid changes in society and the growth of the Internet and emerging the Internet addiction, is there any statistical difference between Internet users’ vision and values? This research is a cross-sectional descriptive study. Study individuals were all internet users of Khalkhal city during 20072008. 200 people (15-25 years old) were selected by chance for the study. The users filled in the Schwartz and Young’s questionnaires. The sum of marks range between 20-40 show normal users, 50-79 show person with mild addiction and 80-100 show person with high addiction. The reliability index of Young’s test was calculated 88% and Schwartz 0.91. for compare data we use SPSS version 16 and t-test statistical method. Data showed that internet has both positive and negative futures and also, results showed that there is significant difference among people in term of stimulation, Power and Hedonism variables (p<0.01). So that, these values in addictive people were more than normal people.
Tourism for Peace?: Reflections on a Village Tourism Project in Cyprus

On 1 May 2004, the Republic of Cyprus entered the European Union, unaccompanied by the Turkish-Cypriot population in the northern third of the island. The Green Line – the militarized border marking the cessation of hostilities in 1974 – now defi nes the outer edge of the European Union, creating a fl uid and uncertain borderland which has become the focus for ongoing att empts to construct both the new Cyprus and the new Europe. Tourism has a central and contradictory role to play in these processes. It off ers an avenue for stimulating economic activity and raising income levels in the Turkish-Cypriot north, and presents an opportunity to develop complementary tourism products north and south which could widen the appeal of the island as a whole and promote collaborative ventures between Greekand TurkishCypriots. On the other hand, such developments face strong resistance from sections of the population north and south, who fear they will lead either to the legitimation and tacit recognition of the Turkish-Cypriot state in the north, or to a return to relations characterized by Greek-Cypriot dominance and Turkish-Cypriot dependence. The paper refl ects on the author’s involvement in a village tourism development project in Cyprus in 2005–2006 in order to explore what an anthropological approach to the use of tourism for political ends can tell us about confl ict, and when, and under what conditions, tourism might be a force for peace and reconciliation.
Concentrations of low molecular weight carboxylic acids and carbonyl compounds in the Aegean Sea (Eastern Mediterranean) and the turnover of pyruvate

In situ concentrations of low molecular weight carboxylic acids and carbonyl compounds were determined in the upper 100 m water column in the Eastern Mediterranean Sea in September 1997. Concentrations ranged from 1 to 13 nM for pyruvate, 1 to 11 nM for glyoxylate and 30 to 70 nM for glycolaldehyde. No distinct diurnal pattern in the depth distribution of carboxylic acids and carbony1 compounds was detectable. Exposure of surface water to solar radiation, however, resulted in photochemical production of acetaldehyde (10 nmol 1-' h-'), acetone/acrolein (6 nmol l" h-') and pyruvate (3 nmol I-' h-'). Depth profiles of the optical properties of the total organic carbon (TOC) exhibited low TOC-normalized fluorescence (excitation 350 nm, emission 450 nm) and absorbance ( a b ~ ~ ~ ~ " , , , ) in the top 25 m, both increasing with depth. This indicates an increasing contribution of refractory molecules to the TOC pool with depth. Uptake rates of pyruvate by heterotrophic bacterioplankton ranged from 0.022 to 0.185 nmol l-' h-' and contributed -10% to the total bacterial carbon production as measured by [3~] leuc ine incorporation. Bio-assay experiments with surface water amended with either 1 pM NO3, 0.4 FM PO4 or 1 pM glucose or in combination decreased pyruvate uptake as compared to the unamended control. Our results reveal that pyruvate might be an important source of carbon for bacterioplankton, with turnover times of pyruvate of 0.7 to 24 d.
Hydroxamic acids in Aegilops species and effects on Rhopalosiphum padi behaviour and fecundity

As an environmentally compatible alternative to the use of conventional insecticides to control cereal aphids, the possibility of exploiting natural resistance to insect pests in wheat species was investigated. Previous work, comparing the antibiotic and antix- enotic effects of hexaploid wheat (Triticum aestivum, AABBDD), tetraploid wheat (Triticum durum, AABB) and some A genome diploid species on the bird cherry-oat aphid, Rhopalosiphum padi L. , found little difference between accessions in the higher ploidy plants, but the diploid species contained attributes that could be important in the breeding for resistance against aphids in the future. This study concentrated on wild accessions of diploid Aegilops species to which the closest ancestor of the B genome donor of hexaploid wheat belongs. The aphid R. padi showed reduced attraction and an increase in the intrinsic rate of population growth on the B genome species tested by compared to the hexaploid control. Investigation of a group of secondary metabolites, the hydroxamic acids or benzoxazinones showed that leaf tissue of one of these (Aegilops speltoides) contains high levels of DIMBOA-glucoside and of the main aglucone, 2,4-dihidroxy-7-methoxy-1,4-benzoxazin-3-one (DIMBOA) while no hydroxamic acids were found in the leaf tissue of Ae. longissima, Ae. bicornis and Ae. sharonensis and only trace levels in Ae. searsii. In those species, an unknown compound was present, which may have an effect on aphid behaviour. The effect of aphid feeding on levels of hydroxamic acids in Ae. speltoides and Ae. sharonensis was also examined. While a localised defence reaction to aphid feeding had been identified in the hexaploid and tetraploid species, a more systemic effect was observed in the diploid Ae. speltoides.
Valuation of ground penetrating radar for the record of structures in fluvio lacustrine soils

En este trabajo se analiza la respuesta del Radar de Penetracion Terrestre (RPT) a las caracteristicas geologicas de suelos fluvio-lacustres. El RPT constituye una herramienta util para el estudio de la estructura del medio geologico debido a que proporciona perfiles continuos del subsuelo (tambien llamados radargramas). La identificacion de estructuras delgadas en las capas de suelos fluvio-lacustres de los radargramas presentados permite evaluar la capacidad de deteccion del RPT Zond 12c para fines estratigraficos. La capacidad de deteccion del metodo depende principalmente de la profundidad alcanzada y de la resolucion obtenida durante la prospeccion, de las frecuencias utilizadas, asi como del sistema electronico para adquisicion y procesamiento de las senales. El principio de la prospeccion se basa en la emision de impulsos electromagneticos de corta duracion, los cuales son captados despues de haber sido reflejados por discontinuidades electricas. Estas se asocian normalmente a discontinuidades fisicas o estructurales en el subsuelo y dependen directamente de las propiedades del mismo.
Optimal Bandwidth Scheduling of Networked Learning Control System Based on Nash Theory and Auction Mechanism

This paper addresses the optimal bandwidth scheduling problem for a double-layer networked learning control system (NLCS). To deal with this issue, auction mechanism is employed, and a dynamic bandwidth scheduling methodology is proposed to allocate the bandwidth for each subsystem. A noncooperative game fairness model is formulated, and the utility function of subsystems is designed. Under this framework, estimation of distribution algorithm (EDA) is used to obtain Nash equilibrium for NLCS. Finally, simulation and experimental results are given to demonstrate the effectiveness of the proposed approach.
ScienceDirect SiliconPV : March 25-27 , 2013 , Hamelin , Germany Role of annealing conditions on surface passivation properties of ALD Al 2 O 3 films

The surface passivation performance of Al2O3 films attracted attention in the field of solar cells and semiconductor devices and depends on the conditions of the applied post-deposition annealing step. The effect of annealing temperature and different annealing atmospheres on the surface passivation quality of atomic layer deposited Al2O3 films was investigated on n-type float-zone Si wafers. Photoconductance decay measurements were carried out to characterize recombination velocities and carrier lifetimes. The chemical and field-effect passivation mechanism, i.e. the interface trap density and the fixed charge density, respectively, were studied by capacitance-voltage experiments. Low surface recombination velocities of Seff,max ~1 cm/s corresponding to a carrier lifetime of 9.0 ms were achieved for samples annealed in O2 atmosphere whereas annealing in H2 and N2 led to slightly higher Seff,max-values ~2 cm/s. The annealing temperature was found to affect both the fixed charge density and the interface trap density whereas in contrast the annealing atmosphere affected only the interface trap density, i.e. the chemical passivation. According to the expectations the highest surface passivation quality is based on a high fixed charge density and a low interface trap density. © 2013 The Authors. Published by Elsevier Ltd.

Comparison of SOFA and APACHEII Scores in Predicting Weaning of Patients from Ventilator in the ICU Ward of Amin Hospital in Isfahan, Iran

Today, mechanical ventilation devices play an effective role in the improvement of patients. Prolonged mechanical ventilation and inappropriate weaning of patients from ventilators have undesirable consequences. To measure the readiness of patients to be weaned from a ventilator, accurate and valid criteria are required. The present study was conducted to compare SOFA with APACHEII scores in predicting the results of weaning patients from the ventilator in the intensive care unit (ICU). This was a descriptive-analytic study of comparative type conducted in 2015 in Isfahan, Iran on patients admitted to the ICU. The study sample was all patients admitted to the ICU of Amin Hospital. Sampling was conducted using the convenience (accessible) sampling method. Overall, 85 patients comprised our sample. Of the 85 patients, 24 patients died and were excluded from the study. In this study, the standard forms of SOFA and APACHEII were used to score patients' conditions. Descriptive statistical tests and the t-test, logistic regression, correlation coefficient, and calculation of specificity, sensitivity and area under ROC curve were used. Then, the data were analyzed using SPSS18 software. In this study, of the 61 patients included in the sample, 15 patients (24.6%) were females and 46 patients (75.4%) were males. In terms of age, the highest frequency distribution was related to patients over 70 years (18%), and 60.7% of the patients had an underlying disease. This study showed that there is a significant relationship between the SOFA and APACHEII scores. However, the values of sensitivity, specificity, positive predictive value, negative predictive value, and area under the ROC curve were higher in the APACHEII scoring system than in SOFA. In addition, the APACHEII score at admission and at first weaning predicted the result of the first weaning of patients from the ventilator. On the other hand, the mortality rate was zero percent in patients who first their weaning of ventilator was successful. While there is a significant relationship between the SOFA and APACHEII scores, the APACHEII scores were a better indicator than SOFA for predicting successful weaning of the patient from ventilator. Also this study show that failure at the first weaning of the patients from ventilator accompanies an increase of mortality.
Unionisation, unemployment and economic growth

This paper employs a simple overlapping generations endogenous growth model with an R&D sector to establish a link between union bargaining power, long-run unemployment and long-run growth. The model consists of a competitive final goods sector, two intermediate goods sectors, one competitive and the other a monopoly and a competitive R&D sector. Increased union bargaining power in the monopolized intermediate-goods sector is shown to increase wages and unemployment in the sector and reduce the economy’s long-run growth rate. This result is shown to hold for both closed- and open-shop unions.
Evolutionary perspectives on the capability accumulation process

There has been an increasing call from academics specialising in operations management to integrate different strategic management perspectives into operations strategy research. Recently some pieces of operations strategy research have used the resource‐based view. It is often suggested that the incorporation of resource‐based view ideas into the field of operations strategy is a search for a new paradigm, yet the ever‐increasing literature suffers from a lack of empirical research. Moreover, operations strategy research from the evolutionary perspective, using longitudinal field data, is almost completely neglected. This paper attempts to make two contributions. The first is to stimulate debate about the incorporation of resource‐based view and dynamic capabilities within operations strategy research. The second is to present a model based on in‐depth field research where the dynamics of the capability accumulation process is explored.
Inertia Compensation While Scanning Screw Threads on Coordinate Measuring Machines

Inertia Compensation While Scanning Screw Threads on Coordinate Measuring Machines Usage of scanning coordinate-measuring machines for inspection of screw threads has become a common practice nowadays. Compared to touch trigger probing, scanning capabilities allow to speed up the measuring process while still maintaining high accuracy. However, in some cases accuracy drastically depends on the scanning speed. In this paper a compensation method is proposed allowing to reduce the influence of inertia of the probing system while scanning screw threads on coordinate-measuring machines.
Database Manipulation Operations on Quantum Systems

Manipulating a database system on a quantum system is an essential aim to benefit from the promising speed-up of quantum computers over classical computers in areas that take a vast amount of storage and processing time such as in databases. In this paper, the basic operations for manipulating the data in a quantum database will be defined, e.g. INSERT, UPDATE, DELETE, SELECT, backing up and restoring a database file. This gives the ability to perform the data processing, that usually takes a long processing time on a classical database system, in a simultaneous way on a quantum system. Defining a quantum version of more advanced concepts used in database systems, e.g. the referential integrity and the relational algebra, is a normal extension to this work.
Olaratumab (LARTRUVO®) as a new therapeutic option in the treatment of patients with advanced soft tissue sarcomas

Olaratumab is a newly approved human monoclonal IgG1 antibody against platelet-derived growth factor alpha (PDGFR-α). In a relatively small, randomised phase 2 trial the drug given in combination with doxorubicin produced an overall survival improvement in patients with unresectable and/or metastatic soft tissue sarcomas. Further studies are necessary to establish the role of this agent in the treatment of advanced sarcomas. In this paper the current clinical data on olaratumab are presented.
African Buffalo Optimization Algorithm for Tuning Parameters of a PID Controller in Automatic Voltage Regulators

In this paper, we present the African Buffalo Optimization (ABO) approach for the metaheuristic tuning of the Proportional, Integral & Derivative (PID) Controller parameters of Automatic Voltage Regulators in electrical power generation and transmission. ABO simulates the movement of African Buffalos as they migrate from place to place all over Africa in search of grazing pastures. The buffalos use just two basic vocalizations, namely the waaa and the maaa to organize the entire herd in their migration and search for food a nd water. Though a recently-designed algorithm, the ABO has been effective and efficient in solving a number of search optimization problems. The highpoints of the ABO include its use of few parameters, constant interactions among the buffalos and the deployment of the exploration and exploitations mechanisms of the algorithm in every iteration. The simulation outcome of the application of ABO to tune the parameters of a PID-Controller parameters of Automatic Voltage Regulators has been very competitive when compared similar outcomes of other metaheuristics tuners: BFO-PID, PSO-PID, GA-PID, PID-PSO, PID Tuner and ACO-PID.
Boundary layer in pastes-Dispacement of a long object through a yield stress fluid

Synopsis When it moves through a yield stress ﬂuid, a solid object continuously reaches and liqueﬁes new solid regions, so that both ﬂow in liquid regions and deformations in solid regions occur. In the present work, we focus on the displacement of a plate through simple yield stress ﬂuids (non-thixotropic). Through force vs velocity and particle imaging velocimetry measurements with a detailed analysis of the deformation history, we are able to identify the solid and liquid regions and their respective role in the ﬂow characteristics. It is shown that the displacement of a long object through a yield stress ﬂuid gives rise to the formation of a liquid boundary layer (BL) of uniform thickness at short distance from the leading edge, while the rest of the material remains solid. The original result is that the thickness of this boundary layer, which is of the order of 10mm, only slightly increases with velocity and does not tend to zero when the velocity tends to zero, in contrast with usual ﬂows of yield stress ﬂuids along solid surfaces. Moreover, it does not change for signiﬁcant variations of the rheological characteristics of the ﬂuid in its liquid regime. We show that these speciﬁc characteristics of the liquid layer are mainly governed by the progressive transition from an elastic solid to a liquid, starting slightly ahead of the leading edge of the plate.

Chemical Compositions of PM_(2.5) at Two Non-Urban Sites from the Polluted Region in Europe

The study presents the analysis of measurement results for the ambient mass concentrations of fine particulate matter (PM_(2.5)), PM_(2.5)-bound carbonaceous matter (OC, EC) and water-soluble ions (Cl^-, NO3^-, SO_4^(2-), Na^+, NH_4^+, K^+, Ca^(2+), Mg^(2+)). The 24-h PM_(2.5) samples were collected in the heating and non-heating seasons at two regional background sites in Southern Poland in 2011-2013. The percentage of the secondary organic and inorganic matter in PM_(2.5) was calculated. Over the whole measurement period, the mean PM_(2.5) concentration was 31.56 μg m^(-3) and 24.92 μg m^(-3) in Raciborz and Zloty Potok, respectively. Regardless of the season, the total carbon percentage in PM_(2.5) was comparable at both sites and amounted ~40%. There were no visible seasonal variations in the secondary organic carbon (SOC) share in PM_(2.5). The mean percentage of the primary organic carbon (POC) in PM_(2.5) was higher than the SOC percentage at both locations. The mean contribution of the water-soluble ions in the PM_(2.5) mass was lower than the TC percentage, with values 20.35% (Zloty Potok) and 33.56% (Raciborz). The total share of the secondary ions (SO_4^(2-), NO_3^- and NH_4^+) in PM_(2.5) was comparable in both measurement periods. It was shown that PM_(2.5) at regional background sites in Southern Poland is significantly different than at similar stations across Europe. It is reflected by higher concentrations of PM_(2.5) and its main components and lower percentage of the secondary ions in the PM_(2.5) mass. The carbonaceous matter percentage in PM_(2.5) is higher than in other parts of Europe.
