Tubular permanent magnet actuators: cogging forces characterization

Tubular permanent magnet actuators are evermore used in demanding industrial and automotive applications. However, these actuators can suffer from large cogging forces, which have a destabilizing effect on the servo control system and compromise position and speed control accuracy. This paper focuses on the identification of the cogging forces by means of finite element software, where an approach is introduced within the 2D finite element analysis to model the linear tubular permanent magnet actuator compared to conventional axisymmetrical models. This gives that the contribution of the stator teeth and finite length of the ferromagnetic armature core to the total cogging force can be separately analyzed. The cogging force predictions is characterized and the effectiveness of the new method is verified comparing the results of the tubular structure in both the axisymmetrical model and 2D finite element model, normally used for rotary machines.
Money demand and economic uncertainty in Barbados

Using the unrestricted error correction model proposed by Pesaran et al (2001), this paper investigates the relationship between economic uncertainty and money demand in Barbados. Results suggest that in the short run, agents tend to increase money holdings in the face of heightened uncertainty. However, this impact does not carry on into the longer term. Rather, the results suggest that nominal assets may become less attractive during prolonged periods of economic uncertainty.
Band-application of phosphorus with farm manure improves phosphorus use efficiency, productivity, and net returns of wheat on sandy clay loam soil

Phosphorus use efficiency (PUE) is very low in alkaline calcareous soils; however, it can be improved by using suitable application methods along with farm manure (FM). The present field study was conducted to optimize phosphorus (P) levels and application methods in order to maximize wheat yield, PUE, and net returns on calcareous soils with and without FM application. Five P soil solution levels, i.e. 0.00, 0.05, 0.10, 0.20, and 0.30 mg P L-1, were maintained according to the Freundlich model through the application of 0, 36, 61, 104, and 142 kg P2O5 ha-1, respectively. The calculated P (0, 36, 61, 104, and 142 kg P2O5 ha-1) was applied by broadcasting, band-placement, and top-dressing, with or without 300 kg ha-1 well-rotted FM. The results revealed that the band-placement technique at 104 kg P2O5 ha-1 improved PUE and wheat output with and without FM application. Furthermore, wheat grain and straw P uptake was high at 142 kg P2O5 ha-1. In addition, protein content and Olsen P were high at 142 kg P2O5 ha-1. The band-placement technique at 104 kg P2O5 ha-1 increased net returns and the cost/benefit ratio. FM application further augmented the productivity, PUE, and net returns under various P levels and application techniques. In conclusion, band-placement of P at 104 kg P2O5 ha-1 with FM improved yield, PUE, and net returns of wheat sown on sandy clay loam calcareous soils.
Lawrence Berkeley National Laboratory Recent Work Title Fluorinated End-Groups in Electrolytes Induce Ordered Electrolyte / Anode Interface

Fluorine based additives have a tremendously beneficial effect on the performance of lithium ion batteries, yet the origin of this phenomenon is unclear. In this paper we show that the formation of a solid electrolyte interphase (SEI) on the anode surface in the first 5 charge / discharge cycles is affected by the stereochemistry of the electrolyte molecules on the anode surface starting at open circuit potential. We have studied an anode specific model system, the reduction of 1,2-diethoxy ethane with LiTFSI, lithium Bis(trifluoromethane)sulfonimide, as salt on amorphous silicon anode and compared the electrochemical response and SEI formation to its fluorinated version BTFEOE, Bis(2,2,2trifluoroethoxy) ethane by sum frequency generation (SFG) vibrational spectroscopy under reaction conditions. Our SFG results suggest that the -CF3 end groups of the linear ether BTFEOE change its adsorption orientation on the a-Si surface at open circuit potential, leading to a better protective layer. Supporting evidence from ex situ scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS) depth profiling measurements show that the fluorinated ether, BTFEOE, yields a smooth SEI on the a-Si surface and enables lithium ion to intercalate deeper into the a-Si bulk.
Sense of coherence as a mediator of stress among high school students in Tromsø, Norway.

School adaptation seems to have an impact on social, psychological, and behavioural outcomes. Empirical evidence on the stress moderating role of the sense of coherence (SOC), which implies to which degree one find life meaningful, comprehensible and manageable, may offer a scope for development of prevention policies. The aim of this study was to examine the relationship and interactions between high school students perceived stress (PSQ), sense of coherence (SOC-13), perceived health condition (HBSC), memories of childhood upbringing separate for mother and fathers parenting style (sEMBU), locus of control (LOC) and degree of conformity (NC). All respondents were at least 18 years during semesters 2007/08. Three high schools in Tromso, here referred to as school A, B and C, participated in the study. Results were analysed for total group, for each gender and also individually for each school. The study included 125 respondents, 61 females and 64 males, who completed a test battery in paper form. The results revealed that youth with a high sense of coherence report less perceived stress, whereas youth with high perceived stress report more health complaints. Males with the highest sense of coherence and females with lowest sense of coherence (SOC) report the strongest correlation between the sense of coherence and health complaints. There were only very weak correlations, in particular for males, between SOC and factors from experienced childhood upbringing, no statistically significant correlations were found. There were no statistically significant correlations between SOC and youths locus of control. Significant gender differences were found in that perceived stress and level of health complaints is significantly higher in females. Health complaints and sense of coherence has the largest predictive power for females and males perceived stress. For males their sense of coherence has an almost equally strong predictive power as perceived health. Evaluation of parallelism shows that SOC and HBSC do not have a significantly different effect on perceived stress in males and females. But the overall level of stress and health complaints is reported as higher in females. Due to methodological limitations, any conclusions about causality cannot be drawn from the present results.
Stepfamilies in Denmark and France. Does the number of previous children from both partners and whether the previous children live with the couple influence fertility

Based on large data sets we compare stepfamilies fertility in Denmark and France related to which partner brought the stepchildren being co-resident or not interactions with shared children and non-monotonous variations with the number of previous stepchildren assuming that the main results should be similar in the two countries. Stepfamilies are increasing in both countries but are most common in Denmark. Almost all co-resident stepfamilies involve a stepfather. If the woman has one child born before the union in France fertility is much lower at shared parity 0 and especially at shared parity 1 but not if the couple already has 2+ shared children. If the woman has 2 children born before the union fertility is higher than if she only has one previous child at shared parities 0 and 1. These strange results are also found in Denmark and will be further studied when more complete data sets are available. (authors)
Use of Stem Cell Suspensions containing Separated Fetal Stem Cells in Complex Treatment of Patients with Essential Hypertension

Objective: To study a complex treatment including stem cell preparations with separated Fetal Stem Cells (FSCs) in suspensions and therapy effect on dynamics of arterial blood pressure in the patients with essential arterial hypertension. Material and methods: Comparative study on 25 patients of the main group suffering from essential arterial hypertension was performed to investigate the effect of complex treatment with inclusion of preparations of FSCs in the suspensions containing extracted stem cells of fetal liver, brain and heart along with conventional therapy on a dynamics of ABP ranges in the patients. Control Group included 25 patients with essential arterial hypertension who were compared to the patients in the main group based on all characteristics. The patients were studied before FSCs therapy, over 1, 3 and 6 months after treatment by use of separated FSCs. Results: Increased regulation of vascular tone, better contractile function of the heart and enhanced excretory function of kidneys leading to decrease of Circulating Blood Volume (CBV), Cardiac Output (CO) and Total Peripheral Resistance (TPR) of vessels have been established in the patients. In addition, systolic function of LV myocardium was improved by way of increasing contractile cellular elements within myocardium and/or due to enhanced functional reserves of cardiomyocytes in the recipient. Conclusion: FSCs therapy proved to be safe and highly effective in stabilization of systemic Arterial Blood Pressure (ABP) and contributed to better life quality among the patients with arterial hypertension.
Improving the Efficiency of Term Weighting in Set of Dynamic Documents

In real information systems, there are few static documents. On the other hand, there are too many documents that their content change during the time that could be considered as signals to improve the quality of information retrieval. Unfortunately, considering all these changes could be time-consuming. In this paper, a method has been proposed that the time of analyzing these changes could be reduced significantly. The main idea of this method is choosing a special part of changes that do not make effective changes in the quality of information retrieval; but it could be possible to reduce the analyzing time. To evaluate the proposed method, three different datasets selected from Wikipedia. Different factors have been assessed in term weighting and the effect of the proposed method investigated on these factors. The results of empirical experiments showed that the proposed method could keep the quality of retrieved information in an acceptable rate and reduce the documents‘ analysis time as a result.
Effects of Seed Treatment Fungicides on Ascochyta pinodes of Field Pea Under Controlled and Field Conditions

Nine fungicides namely thiram, chlorothalonil, metalaxyl, benomyl, thiabendazole, carbendazim, thiophanate-methyl, benalaxyl and iprodione at the rate of 0.001, 0.01, 0.1, 1.0, 10 g/L medium ai were tested in vitro against Ascochyta pinodes (teleomorph = Mycosphaerella pinodes) from field pea for inhibition of mycelial growth. Tests were also conducted on the effect of these fungicides on seed mycoflora at the rate of 2g ai/kg seed. Further studies were carried out on the effects of selected fungicides on seedling infection in growth chamber and field conditions. Radial growth of A. pinodes culture was completely inhibited by carbendazim and thiabendazole at the lowest concentration tested (0.001 g/L), benomyl at 0.01 g/L, thiram, thiophanate-methyl and iprodione at 0.1 g/L. Other fungicides affected the growth at various degrees . Seed treatment with carbendazim, chlorothalonil and iprodione completely inhibited the recovery of A. pinodes from treated seeds while 2 to 3% incidence was obtained for thiram, benomyl and thiabendazole. Untreated seeds showed 16% incidence while benalaxyl and metalaxyl gave 15 and 12% incidence, respectively. Seedling infection in growth chamber was completely controlled by carbendazim and iprodione and a reduction of 4.6% by chlorothalonil. In field trial, seed treatment with fungicides didn’t affect emergence date while there was significant difference (p = 0.05) due to variety. However, carbendazim and iprodione had high emergence on all the three varieties and significantly (p < 0.05) reduced the incidence of Ascochyta infection at both locations at early development period of the crop. Infection appeared in late July and a mean incidence of was 0.03, 3.6, 7.6 and 97.1% on 28 July, 5 August, 12 August and 19August at Denbi, respectively. But at Holetta, the incidence was 0.04, 4.0 and 96.9% on 28 July, 5 August and 12 August, respectively. At both locations, a fast increase from about 10 to 100% of incidence was observed within a week time, but at different weeks. Blight severity was slightly affected at the beginning of the season and became similar soon as the season progressed. A mean seed yield of 2.15 t/ha was obtained at Holetta while it was only 0.80 t/ha at Denbi that were significantly (p < 0.05) different. This was due to difference in blight pressure. Generally, treating seeds with carbendazim improved seed yield by 13.2% and with iprodione by 12.5% over the untreated control. Seed treatment with fungicides could be used as a component of
Do Credit Derivatives Dampen Political Risk: The Case of Brazil Post 1998

En este documento analizamos el cambio producido en la relacion entre los estados emergentes (en este caso, Brasil) y los mercados financieros. Este cambio viene dado por los desarrollos en el area de la gestion de riesgos financieros. El uso de los intercambios predefinidos de credito ha garantizado que el riesgo preestablecido de la deuda publica de Brasil se comparta entre un amplio numero de participantes del mercado. Esto significa que el estado de Brasil ya no se enfrenta a un grupo homogeneo de inversores capaces de acordar una accion conjunta. El riesgo politico sigue existiendo en los spreads ofrecidos por un emisor de deuda publica como Brasil, pero el debilitamiento de la relacion entre los mercados de deuda y los inversores indica que, en el futuro, las crisis financieras podrian ser menos probables.
Novel Automated Patch-clamp Assays on Stem Cell-derived Cardiomyocytes: Will they Standardize In Vitro Pharmacology and Arrhythmia Research?

Recent progress in embryonic stem cell and human induced pluripotent stem cell technology allowed effective generation of cultured cardiomyocyte preparations with over 99% purity, rendering them suitable for automated patchclamp approaches. Compared to current high-throughput drug screening methods, such as fluorescence assays using calcium-sensitive or transmembrane potential-sensitive dyes, or field potential recordings and activation mapping using multi-electrode arrays, patch-clamp experiments offer the possibility to combine action potential recordings in current-clamp mode with detailed characterization of drug effects on multiple ion current components with carefully designed voltage-clamp protocols, leading to an in-depth understanding of arrhythmogenesis conditions and mechanisms, especially when combined with cellular electrophysiology computerized models. The recently issued Comprehensive in vitro ProArrhythmia Assay (CiPA) guidelines emphasize the importance of pharmacological tests on multiple cardiac ion channels, including at least Nav1.5 (early and late), Cav1.2, hERG1, Kv7.1/minK, and Kir2.1, via voltage-clamp protocols, instead of simple hERG screening, combined with computer modeling, in order to determine the proarrhythmic liability of a drug candidate. In addition, patch-clamp assays on patient-specific induced pluripotent stem cell-derived cardiomyocytes will enhance current molecular diagnosis methods in cardiac channelopathies by identification of the faulty current component and individualized screening of drug sensitivity of mutant channels, a step forward for personalized medicine approaches.
Substrate Specific Amidolysis of p-Nitroanilides of Amino Acids using Phosphonate Analogue Imprinted Chymotrypsin Mimics

Focusing on bio-recognition, highly crosslinked TSA–built-polymer catalysts were synthesized as chymotrypsin mimics by molecular imprinting technique for substrate specific amidolysis of pnitroanilide of amino acids based on the principle of cooperative catalysis. The polymers having enzyme-like behaviour were prepared using methacryloyl-L-histidine, methacryloyl-L-aspartic acid and 4-vinylpyridine as the functional monomers, phenyl-1- (N-benzyloxy carbonylamino) -2-(phenyl) ethyl phosphonate, the analogue of transition state of amide hydrolysis as the template and methacrylic crosslinker EGDMA as the crosslinking agent. The easy insertion of the substrate followed by selective stabilization of the T.S of amidolysis in the “3-D memorized cavity” in the polymer matrix is responsible for the enhanced substrate specificity of the imprinted chymotrypsin mimics. Cost effective synthesis, ease of preparation, high thermal stability, reusability and higher shelf life make the enzyme mimics highly efficient.
Leaders management and personnel controlling in SMEs

The target of this article is to introduce leaders management and personnel controlling in small and medium-sized companies (SMEs), from the strategic and operational points of view, as the greatest competitive advantage of SMEs in the coming years will not be products or financial or technological resources, but employees. Strategic controlling includes organizational architecture linked to managerial assumptions, both of which are necessary to be adopted if business success should be achieved. The article presents a horizontal and vertical manager model that helps to assess managers and their abilities. Operational personnel controlling then focuses on personnel plans and productivity management.
Elastic light-by-light scattering in a nonminimal Lorentz violation scenario

In the last years the Lorentz Violation scheme was implemented in QFT, in special in standard model of particle physics, in an attempt to explain our actual open problems. In this work we analyze nonminimal couplings between a Lorentz-violating 4-vector and the photon field and the leptonic current of QED. The 1-loop contribution of the elastic photon-photon scattering is showed and the novel characteristics which arose are pointed out.
A Statistical Approach to Term Extraction

This paper argues in favor of a statistical approach to terminology extraction, general to all languages but with language specific parameters. In contrast to many application-oriented terminology studies, which are focused on a particular language and domain, this paper adopts some general principles of the statistical properties of terms and a method to obtain the corresponding language specific parameters. This method is used for the automatic identification of terminology and is quantitatively evaluated in an empirical study of English medical terms. The proposal is theoretically and computationally simple and disregards resources such as linguistic or ontological knowledge. The algorithm learns to identify terms during a training phase where it is shown examples of both terminological and non-terminological units. With these examples, the algorithm creates a model of the terminology that accounts for the frequency of lexical, morphological and syntactic elements of the terms in relation to the non-terminological vocabulary. The model is then used for the later identification of new terminology in previously unseen text. The comparative evaluation shows that performance is significantly higher than other well-known systems.
Is the theory of reasoned action valid for Ar-Rahnu? an empirical investigation

This study examines the applicability of theory of reasoned action (TRA) in a context of Islamic pawnshop using structural equation modelling (SEM). The present study presents a simplified theory of TRA, hence it is intended to test whether the two constructs in the theory are acceptable or not in a newly context of Islamic pawnshop. The simplified theory is tested using survey data from 250 respondents. Out of these, only 221 questionnaires are found to be usable whilst the rest are omitted owing to the incomplete responses. The results reveal that attitude was significantly related to the intention to use Islamic pawnshop. Subjective norm was also significantly associated with the intention to use Islamic pawnshop. In sum, the present study provides us valuable insights for service providers to future planning of Islamic pawnshop businesses.
Semiclassical limitations for photon emission in strong external fields

The semi-classical heuristic emission formula of Baier-Katkov [Sov. Phys. JETP \textbf{26}, 854 (1968)] is well-known to describe radiation of an ultrarelativistic electron in strong external fields employing the electron's classical trajectory. To find the limitations of the Baier-Katkov approach, we investigate electron radiation in a strong rotating electric field quantum mechanically using the Wentzel-Kramers-Brillouin approximation. Except for an ultrarelativistic velocity, it is shown that an additional condition is required in order to recover the widely used semi-classical result. A violation of this condition leads to two consequences. First, it gives rise to qualitative discrepancy in harmonic spectra between the two approaches. Second, the quantum harmonic spectra are determined not only by the classical trajectory but also by the dispersion relation of the effective photons of the external field.
Regional Labour Productivity in The Netherlands - Diversification and Agglomeration Economies

This paper studies the extent to which diversification and agglomeration effects account for regional differences in labour productivity levels and labour productivity growth. Using a large set of regional data for The Netherlands for 40 labour market areas between 1990-2001 we find that roughly 60% of the explained variation in regional productivity differences and 55% of the regional growth differences can be attributed to indicators of diversification and agglomeration effects. A sensitivity analysis shows that these effects are fairly robust.
The Effect of Creatine Supplementation on Body Composition and Bone Health in the Elderly

Introduction: Ageing is associated with body composition changes, including decreases in muscle mass and bone content and increases in fat mass. Creatine supplementation is associated with increases in lean Tissue mass in athletes, leading to increased strength and power. There has been recent interest in if creatine supplementation may have similar effects in older individuals, to offset the changes seen in body composition and increase quality of life. Aims: This review assesses the current literature on whether creatine supplementation in the presence or absence of resistance training improves body composition and bone health in older adults. Results: In terms of resistance training and creatine supplementation in Combination, there is evidence for increased lean body mass following long-term investigations, above that of resistance training with placebo. Studies without resistance training mostly use acute strategies of creatine supplementation and have produced conflicting reports on lean body mass. Body fat percentage does not seem to be altered by either resistance training or creatine supplementation. The literature on creatine supplementation’s effect on bone health is also inconclusive, with some reports showing significant increases in bone mineral density, whereas several others show no effect. Conclusions: Creatine supplementation in the elderly may lead to increased lean body mass, and increased bone strength; however these results are far from conclusive. Dosing and timing supplementation protocols between studies may be responsible for the different results and future studies should concentrate on determining if acute or chronic creatine supplementation has a more beneficial effect on body composition in the elderly.
