WIND TURBINES AND EARTHQUAKES

Modern wind turbines have been mainly erected in regions where earthquakes are rare or normally weak. More recently wind farms in Africa, Asia ad southern Europe have been developed where stability under earthquakes becomes an issue. So far earthquake loads have been analyzed with methods adapted from civil engineering which may not be adequate for the dynamics occurring above the yaw bearing. In this talk we present results that have been obtained by taking into account ground accelerations in a state-of-the-art simulation code for wind turbines. Synthetic 3-dimensional accelerograms consistent with the relevant standards are generated and applied to the turbine foundation. The structural dynamics of a sample turbine, the Nordex N80 with 60m hub height, is analyzed, leading to a detailed picture of the loads occurring during earthquakes. A comparison with the design loads and an assessment with regard to the main components are carried out. e-mail: uritschel@windrad-engineering.de
Validation of the relative insensitivity of volumetric-modulated arc therapy (VMAT) plan quality to gantry space resolution

Abstract Volumetric-modulated arc therapy (VMAT) is an efficient form of radiotherapy used to deliver intensity-modulated radiotherapy beams. The aim of this study was to investigate the relative insensitivity of VMAT plan quality to gantry angle spacing (GS). Most previous VMAT planning and dosimetric work for GS resolution has been conducted for single arc VMAT. In this work, a quantitative comparison of dose–volume indices (DIs) was made for partial-, single- and double-arc VMAT plans optimized at 2°, 3° and 4° GS, representing a large variation in deliverable multileaf collimator segments. VMAT plans of six prostate cancer and six head-and-neck cancer patients were simulated for an Elekta SynergyS® Linac (Elekta Ltd, Crawley, UK), using the SmartArc™ module of Pinnacle³ TPS, (version 9.2, Philips Healthcare). All optimization techniques generated clinically acceptable VMAT plans, except for the single-arc for the head-and-neck cancer patients. Plan quality was assessed by comparing the DIs for the planning target volume, organs at risk and normal tissue. A GS of 2°, with finest resolution and consequently highest intensity modulation, was considered to be the reference, and this was compared with GS 3° and 4°. The differences between the majority of reference DIs and compared DIs were <2%. The metrics, such as treatment plan optimization time and pretreatment (phantom) dosimetric calculation time, supported the use of a GS of 4°. The ArcCHECK™ phantom–measured dosimetric agreement verifications resulted in a >95.0% passing rate, using the criteria for γ (3%, 3 mm). In conclusion, a GS of 4° is an optimal choice for minimal usage of planning resources without compromise of plan quality.
Bandwidth optimization using fractal geometry on rectangular microstrip patch antenna with DGS for wireless applications

To have small, compatible and affordable antennas is the need of today's mobile devices. Microstrip antennas are best choice for wireless devices because of characteristics like low weight, ease of fabrication and low cost. But on the other hand, microstrip antenna also suffers from disadvantages like they have less bandwidth and gain. So measure issues for consideration are multiband and wideband operation of antenna. In order to obtain multiband and wideband characteristics, different techniques can be used like cutting a slot in patch, fractal geometry and DGS (Defected Ground structure). In order to increase bandwidth, DGS can be used. It is to be noted that within particular area of ground different DGS can produce different resonant frequencies and different bandwidth. In this paper, the use of fractal geometry with three iterations has been proposed. This results in multiband operation of patch antenna with added advantage of size reduction. Further the wideband characteristic of antenna is improved by applying DGS. Simulation results show that an improvement in bandwidth of 10% could be achieved for S-band patch antenna.
Bartonella clarridgeiae in Fleas , Tahiti , French Polynesia

were conducted by using MEGA version 4.1 (www.megasoftware. net). The partial lppA gene nucleotide sequences of isolates GN407 and GN408 were submitted to GenBank under accession nos. HQ699892 and HQ699893, respectively. PCR amplifi cations of the 2 joint fl uids and their cultures were positive for M. leachii. When we compared the complete 16S rRNA gene and the partial lppA gene, the 2 isolates from the same epizootic shared 100% nt identity. For 16S rRNA gene, the isolates shared 99.9%, 99.9%, and 99.7% nt identities to M. leachii PG50, M. capricolum subsp. capricolum, and M. mycoides subsp. mycoides small colony, respectively. For partial lppA gene, the isolates shared 99.6%, 95.1%, and 69.6% nt identities to M. leachii PG50, M. mycoides subsp. mycoides small colony, and M. capricolum subsp. capricolum, respectively. Intraarticular inoculation of the passage cultures successfully reproduced the polyarthritis in calves 1 month of age. Thus, there are notable similarities between our fi ndings and those reported in Australia (3). Multidisciplinary procedures, including clinical assessment and comprehensive laboratory investigations of affected calves, were used to identify the etiologic agent. The results showed that the outbreak of the serious polyarthritis in calves was caused by M. leachii. Our detection of M. leachii in China confi rms a wider geographic presence of this type of Mycoplasma spp. in cattle and suggests M. leachii is common and potentially distributed worldwide. Currently, the source of M. leachii infection and its means of spread have not been established. However, our epidemiologic and clinical investigations indicated clear evidence of seminal infection because all calves with arthritis were from dams that were fertilized by using the same batch of semen, and cows in the same herd that were fertilized by using a different batch of semen delivered healthy calves. More epidemiologic, molecular, and pathogenic studies are required to determine the relevance, distribution, importance, and diversity of M. leachii in cattle.
Industry 4.0: Employers Expectations of Accounting Graduates and its Implications on Teaching and Learning Practices

This study aims to examine employers’ expectations of knowledge and skills in accounting graduates before hiring them. Using a qualitative approach on accounting practitioners and academics, this study shows that the expectations employers place on accounting students in the Industry 4.0 environment is set to change significantly, particularly in technologies used in the preparation, reporting and dissemination of financial information. Specifically, this study showcases the strong views expressed by a panel of experts comprising accounting practitioners, particularly on the subjects of job redundancies and the degree of replacement of human activities by electronic devices and machines. The replacement of physical human activities by machines is therefore expected. In addition, accounting practitioners see the need for accounting graduates to focus on continuous learning and education, particularly in acquiring knowledge and skills in IT. Hence, there is a need for academics and universities to incorporate various accounting technologies and simulations that are applicable to the Industry 4.0 environment, in their teaching and learning activities. This study contributes to existing education literature by providing new findings on the expectations of employers of future accounting graduates. In addition, this study contributes to the further understanding of academics and universities in strategizing ways and innovating new teaching and learning approaches so that accounting graduates’ employability can be enhanced and the needs of the current market for accountants can be accommodated.

Interference between Two Tripped Cylinders in a Cross Flow

Flow interference is investigated between two tripped cylinders of identical diameter D at stagger angle  = 0 ~ 180 and gap spacing ratio P (= P/D) = 0.1 ~ 5, where P is the gap width between the cylinders and  is the angle between the freestream velocity and the line connecting the cylinder centers. Two tripwires, each of diameter 0.1D, were attached on each cylinder at azimuthal angle  = 30, respectively. Time-mean drag (CD) and fluctuating drag (CDf) and lift (CLf) on the two tripped cylinders were measured and compared with those on plain cylinders. Surface pressure measurements were also carried out to assimilate the fluid dynamics around the cylinders. CD, CDf and CLf all for the plain cylinders are strong function of  and P due to strong mutual interference between the cylinders, connected to six interactions, namely boundary layer and cylinder, shear-layer/wake and cylinder, shear layer and shear layer, vortex and cylinder, vortex and shear layer, and vortex and vortex interactions. CD, CDf and CLf are very large for vortex and cylinder, vortex and shear layer, and vortex and vortex interactions, i.e., the interactions where vortex is involved. On the other hand, the interference as well as the strong interactions involving vortex are suppressed for the tripped cylinders, resulting in insignificant variations in CD, CDf and CLf with  and P . In most of the (, P ) region, the suppressions in CD, CDf and CLf are about 58%, 65% and 85%, respectively, with maximum suppressions 60%, 80% and 90%.
Theoretical geodesy

The paper presents a summary of research activities concerning theoretical geodesy performed in Poland in the period of 2011–2014. It contains the results of research on new methods of the parameter estimation, a study on robustness properties of the M-estimation, control network and deformation analysis, and geodetic time series analysis. The main achievements in the geodetic parameter estimation involve a new model of the M-estimation with probabilistic models of geodetic observations, a new Shift-Msplit estimation, which allows to estimate a vector of parameter differences and the Shift-Msplit that is a generalisation of Shift-Msplit estimation if the design matrix A of a functional model has not a full column rank. The new algorithms of the coordinates conversion between the Cartesian and geodetic coordinates, both on the rotational and triaxial ellipsoid can be mentioned as a highlights of the research of the last four years. New parameter estimation models developed have been adopted and successfully applied to the control network and deformation analysis. New algorithms based on the wavelet, Fourier and Hilbert transforms were applied to find time-frequency characteristics of geodetic and geophysical time series as well as time-frequency relations between them. Statistical properties of these time series are also presented using different statistical tests as well as 2nd, 3rd and 4th moments about the mean. The new forecasts methods are presented which enable prediction of the considered time series in different frequency bands.
Preliminary Web-Based Measures Development for GHB: Expectancies, Functions, and Withdrawal

Background: Much of what is understood regarding gamma hydroxybutyrate (GHB) treatment is based on hospital case studies for overdose and withdrawal, and there are currently no measures developed specifically for GHB or its analogs (e.g., gamma butyrolactone and 1,4-butanediol) to assess drug effect expectancies, reasons for starting use, withdrawal effects, and knowledge and opinions about use. Objectives: This pilot study (N = 61) was conducted to begin measures development to assess experiences, functions of use, and opinions regarding use as indicated by respondents taking a Web-based survey. Methods: Minimum average partial correlation and parallel analysis procedures are employed to create scales. Results: Scales were developed to assess expectancies, reasons for use, withdrawal, and knowledge/opinions of use with median α = . 79 and that account for 8.69–24.17% of the variance. Conclusion: Scales have relatively good psychometric properties and replication is needed. Scientific Significance: GHB-specific measures may greatly assist in furthering our understanding of protective and risk factors for use, and withdrawal phenomena.
Effect of Different Types of Organic Manure and Mulching on the Growth and Yield of Carrot ( Daucus Carota L . )

An experiment was conducted at the Horticulture Farm of Sher-e-Bangla Agricultural University, Bangladesh during the period from November 2013 to March 2014 to study the effect of different types of organic manure (no organic manure, cowdung, compost and litter) and mulching on (non-mulch, water hyacinth, rice straw and black polythene) the growth and yield of carrot. The experiment was conducted in a Randomized Complete Block Design with three replications. Application of organic manure and mulching significantly influenced the growth and yield of carrot. Cowdung resulted in the highest gross yield (39.05 t/ha) whereas, the plants received no organic manure produced the lowest for the same (33.03 t/ha). The highest gross (39.12 t/ha) and marketable (35.79 t/ha) yield was obtained from the black polythene mulch while the lowest was obtained from non mulched plot. Cowdung with black polythene mulch produced the highest yield (42.75 t/ha) followed by that of application of litter with black polythene mulch (41.46 t/ha). The lowest (32.00 t/ha) was recorded from the control.
Influence of process parameters on mechanical performance and bonding area of AA2024/carbon-fiber-reinforced poly(phenylene sulfide) friction spot single lap joints

Friction spot joining has been shown to be a potential technology to produce metal-composite hybrid joints. In this study, the effects of friction spot joining process parameters on the bonding area and mechanical performance of single lap joints were investigated using full-factorial design of experiments and analysis of variance. The main process parameters with significant influence on the bonding area were joining pressure, tool rotational speed and joining time. Joints with ultimate lap shear forces varying between 1698 ± 92 N and 2310 ± 155 N were obtained. Tool rotational speed and joining pressure displayed the highest influence on the lap shear strength of the joints followed by tool plunge depth, whereas the joining time was not statistically significant. The interaction between the rotational speed and joining time was the only interaction with a significant effect on the mechanical performance. Furthermore, the displacement at peak load and joint failure energy changed from 0.5 ± 0.0 mm to 0.8 ± 0.1 mm and 0.55 ± 0.04 to 0.97 ± 0.12 J, respectively, suggesting brittle fracture of the joints. In general, a larger bonding area as a result of higher heat input led to increased mechanical performance. The generated regression model by the analysis of variance was used to identify an optimized set of parameters for increasing the lap shear strength of the joints. Finally, it was demonstrated that higher heat input increased the amount of voids and defects in the joints because of the higher amount of entrapped air in the low viscosity molten polymer, as well as the large difference in the shrinkage properties of the matrix and carbon fibers. However, no correlation was observed between the area fraction of the voids and mechanical performance because the strength of the joints is dominated by the bonding area. Furthermore, the process temperature was monitored, which varied in the range of 370°C to 474°C.
Increased Levels of Adrenocortical and Gonadal Hormones in Mild to Moderate Alzheimer’s Disease

Hormonal changes during normal aging include decreasing levels of gonadal hormones and adrenal androgens. These hormones influence multiple nervous functions, including cognition and mood. Related to this, abnormalities at several levels of the hypothalamic-pituitary-adrenal axis (HPA) have been reported in patients with Alzheimer’s disease (AD). We studied steroid hormones in 33 patients with mild to moderate AD (12 men; 21 women, 76.4 ± 7.8 years) and 22 healthy elderly controls (10 men; 12 women, 75.4 ± 7.5 years old, respectively). Basal levels of serum cortisol, dehydroepiandrosterone (DHEA) and androstenedione were significantly increased in AD patients. Women with AD had significantly higher levels of DHEA and androstenedione. Serum estradiol levels were non-significantly increased in women with AD. After adjustment for age and BMI women with AD had significantly increased levels of androstenedione and DHEA. Increased gonadal hormone levels in mild to moderate AD may reflect an increased secretion, and/or alterations in metabolism of these hormones. This may influence the symptomatology and progression of the disease.
EFFECT OF SUB-ZERO TREATMENT ON MECHANICAL PROPERTIES OF VANADIS 6 PM LEDEBURITIC TOOL STEEL

The P/M Vanadis 6 cold work steel was austenitized, quenched and tempered. For selected sets of specimens, also sub-zero period was inserted between quenching and tempering. The structure, hardness and three point bending strength was investigated as a function parameters of heat treatment. The asquenched hardness of the material raises with the use of the sub-zero period. On the other side, the use of sub-zero period results in a slight hardness decrease of the as-tempered material. Furthermore it was found that the three point bending strength decreased markedly with increased austenitizing temperature and also slightly with the use of sub-zero treatment. The lowering of bending strength with increasing austenitizing temperature can be considered as natural because of the austenitic grain growth. On the other hand, the lowering of bending strength due to the use of sub-zero processing can not be explained as simply as expected on first sight. The situation is more complex since the hardness behaves in a rather surprising way, which is discussed in the paper.
Controllability of Linear Stochastic Systems in Hilbert Spaces

The classical theory of controllability for deterministic systems is extended to linear stochastic systems defined on infinite-dimensional Hilbert spaces. Three types of stochastic controllability are studied: approximate, complete, and S-controllability. Tests for complete, approximate, and S-controllabilities are proved and the relation between the controllability of linear stochastic systems and the controllability of the corresponding deterministic systems is studied. 2001 Aca-
Effect of Soil Depth on Inelastic Displacement Spectra

In the present paper, effect of soil depth on acceleration spectra, displacement spectra, amplification factors and displacement modification factors have been studied analytically. 1-D ground response analysis has been carried out for the Treasure Island geotechnical array site profile, which represents a soft-soil/rock geological profile, assuming different depths of the bedrock. Spectrum compatible time histories corresponding to NEHRP site class “B” were generated using a wavelet based procedure, corresponding to two level of seismicity, that is, PGA of 0.05g and 0.36 g, at rock outcrop. The effect of soil depth on the shape of response spectra and amplification factors is presented. The analytically obtained displacement modification factors (i.e. ratios of inelastic spectral displacement to elastic spectral displacement) are compared with empirical equations proposed by different researchers. The effect of variation in soil stratum depth for the same site class, is significant on the shape of response spectra and amplification factors; however, the effect on displacement modification factor is negligible.
Cosmic ray energy loss in the heliosphere: Direct evidence from electron‐capture‐decay secondary isotopes

Measurements by the Cosmic Ray Isotope Spectrometer (CRIS) on the Advanced Composition Explorer (ACE) spacecraft provide direct evidence that galactic cosmic rays lose energy as a result of their interactions with magnetic fields expanding with the solar wind. The secondary isotopes ^(49)V and ^(51)Cr can decay to ^(49)Ti and ^(51)V, respectively, only by electron capture. The observed abundances of these isotopes are directly related to the probability of attaching an electron from the interstellar medium; this probability decreases strongly with increasing energy around a few hundred MeV/nucleon. At the highest energies observed by CRIS, electron attachment on these nuclides is very unlikely, and thus ^(49)V and ^(51)Cr are essentially stable. At lower energies, attachment and decay do occur. Comparison of the energy dependence of the daughter/parent ratios ^(49)Ti/^(49)V and ^(51)V/^(51)Cr during solar minimum and solar maximum conditions confirms that increased energy loss occurs during solar maximum. This analysis indicates an increase in the modulation parameter ϕ of about 400 to 700 MV corresponding to an increase in average energy loss for these elements of about 200 to 300 MeV/nucleon.
