An atlas of line profile studies for SU UMa type cataclysmic variables

We present H line-profile analyses for the seven SU UMa type dwarf novae AK Cnc, WX Cet, AQ Eri, VW Hyi, RZ Leo, TU Men, and HS Vir. All data sets are treated in the same manner, applying a sequence of techniques for each system. The basic ingredients of this sequence are the diagnostic diagram to determine the zero point of the orbital phase, and Doppler tomography to visualise the emission distribution. We furthermore introduce a new qualitative way of to evaluate the Doppler fit, by comparing the line profile of the reconstructed with the original spectrum in the form of the V=R plot. We present the results of the analysis in the compact form of an atlas, allowing a direct comparison of the emission distribution in our targets. Although most of the data sets were not taken with the intention of a line-profile analysis, we obtain significant results and are able to indicate the type of the additional emission in these systems. Our objects should have in principle very similar physical properties, i.e. they cover only a small range in orbital periods, mass ratios, and mass-transfer rates. Nevertheless, we find a large variety of phenomena both with respect to the individual systems and also within individual data sets of the same object. This includes "canonical" additional emission components from the secondary star and the bright spot, but also emission from the leading side of the accretion disc.

The measurements of pollution in Bogota require methodologies that allow its analysis; therefore, at the same time, that diagnoses are issued. Below is the functional principal component analysis to reporting material particulate matter PM10. As a result, an appropriate methodology for treating large amounts of data is developed because it summarizes functional statistics such as the average and the covariance obtaining a diagnostic of the behavior of the medic results.
Using Non-traditional Writing as aTool in Learning Chemistry

This study investigated the effect of using a non-traditional writing task and different audiences on 9th grade students’ conceptual understanding of a chemistry unit on mixture. 524 students instructed by 3 chemistry teachers in 2 public high schools participated in this study. Upon completion of the mixture unit, 181 students engaged in traditional writing activities, 121 students wrote a letter to a younger audience, 92 students wrote a letter to their peers, and 130 students wrote a letter to their teacher. Mixture achievement test was administered as a pre- and posttest to all the groups to assess students’ understanding of mixture concepts. Semi-structured interviews were conducted with 24 students from the non-traditional writing group at the end of the instruction to understand students’ ideas about non-traditional writing task. Posttest analyses indicated that non-traditional writing group outperformed the traditional writing group, and the groups that wrote to peers and younger students performed better than those that wrote to the teacher, when the effects of the pretest scores were controlled. The results also showed that students’ performance on the writing task significantly differed with respect to the audience. Moreover, interview results revealed that non-traditional writing tasks were very helpful in students’ understanding of the mixture concepts.
Hydrological influences on long-term gas flow trends at locations in the Vogtland/NW Bohemian seismic region (German-Czech border)

One of the typical methods for the identification of seismo-hydrological effects is to monitor changes in the free gas flow throughout springs or mofettes. For several years, the gas flow regime of mineral springs at Bad Brambach (Germany) and mofettes in the Nature Park Soos (Czech Republic) and its dependence on hydro-/meteorological parameters have been studied. The mineral spring Wettinquelle, Bad Brambach, is a well-known seismo- hydrologically sensitive location for swarmquakes at a special epicentral area of NW Bohemia. Since 2000, a slight upward trend in the gas flow of three Bad Brambach mineral springs has been observed, which became stronger after the Eisenquelle spring capture reconstruction (winter 2003/2004). Similar behaviour could be detected at a mofette in Soos. The results correspond to a 3He/4He mantle ratio increase in gases at mofettes in the Cheb Basin (CZ) traced by other authors for more than 12 years, and could give hints for a higher degassing activity of the magma body below that area. Common and special properties in the degassing regimes of the Bad Brambach and Soos locations are discussed. It is demonstrated that the long-term gas flow trend was interrupted in 2003 because of very low groundwater levels. This effect was amplified by the artificial groundwater lowering during the Eisenquelle spring capture reconstruction.
Role of atmospheric circulations in haze pollution in December 2016

Abstract. In the east of China, recent haze pollution has been severe and damaging. In addition to anthropogenic emissions, atmospheric circulations and local meteorological conditions were conducive factors. The number of December haze days over North China and the Huanghuai area has increased sharply since 2010 and was greatest in 2016. During 2016, the most aggressive control measures for anthropogenic emissions were implemented from 16 to 21 December, but the most severe haze pollution still occurred, covering approximately 25 % of the land area of China and lasting for 6 days. The atmospheric circulations must play critical roles in the sub-seasonal haze events. Actually, the positive phase of the East Atlantic–West Russia pattern in the middle troposphere strengthened the anomalous anti-cyclone over the NH area that confined vertical motion below. The associated southerly anomalies made the cold air and surface wind speed weaker, but enhanced the humid flow. Thus, the horizontal and vertical dispersion of atmospheric particulates was suppressed and the pollutants gathered within a narrow space. In December 2016, these key indices were strongly beneficial for haze occurrence and combined to result in the severest haze pollution. The influences of the preceding autumn sea surface temperature near the Gulf of Alaska and the subtropical eastern Pacific, October–November snow cover in western Siberia, and associated physical processes on haze pollution are also discussed.
An Examination of the Components that Increase Acceptance of Smartphones among Healthcare Professionals

Objective: The professional benefits of mobile computing and communication devices such as the smartphone promise to alter the delivery of healthcare services. Historically the healthcare industry has trailed other business sectors in the adoption of technology. Yet, it appears that smartphones are increasingly being embraced by healthcare professionals such as physicians and nurses. Thus, the objective of this study was to investigate the potential factors that may affect the adoption of a smartphone by healthcare professionals. Methods: It is unclear which factors affect the acceptance of mobile computing devices by healthcare professionals. This study integrates the factors from the Technology Acceptance Model, Self-Efficacy, and the Innovation Diffusion Theory to help explain the components which increase smartphone acceptance among healthcare professionals in two countries. We collected 153 surveys from two countries: 88 from the United States and 65 from Taiwan. Results: The results showed that attitude toward using a smartphone and smartphone selfefficacy had a direct positive influence on the intention to use a smartphone. This study also demonstrated that perceived usefulness and task relatedness indirectly influenced the intention to use a smartphone. Discussion: Healthcare professionals who feel they can successfully master the functions of a smartphone are more apt to use the technology. The findings of this study appear to substantiate that healthcare professionals will increasingly embrace smartphones when they perceive them as a useful accompanying tool to further assist with the completion of clinical tasks. Conclusion: As the use of smartphones continues to proliferate, our study should further help researchers more fully understand salient factors which encourage adoption of mobile technologies. Thus, future smartphone applications and software programs can target specific needs of health professionals.

Pricing Strategies by European Traditional and Low Cost Airlines: Or, When is it the Best Time to Book on Line?

It is often assumed that the airlines’ fares increase monotonically over time, peaking a few days before the departure. Using fares for about 650 thousand flights operated by both Low-Cost and Full Service Carriers, we show several instances in which the monotonic property does not hold. We also show that the volatility of fares increase in the last four weeks before departure, which is the period when the airlines can formulate a better prediction for a flight’s load factor. Finally, especially within the last two weeks, Full Service Carriers may offer lower fares than those posted by Low Cost Carriers.
The Relationship Between Directors' Independence, Reputation and Management Earnings Forecasts

Informative management earnings forecasts potentially reduce information asymmetries in capital markets. We examine the relationship between corporate governance and management earnings forecasts. We extend the prior literature by examining the impact of independent director reputation on characteristics of management forecasts, by refining the previously used proxy for director independence and by distinguishing between routine and non-routine forecasts in the Australian governance environment. We find a significant positive relationship between the likelihood and frequency of firms issuing management earnings forecasts and our measures of audit committee independence and independent director reputation but not board independence. However, there is some evidence that director independence is related to more specific forecasts. These results are driven by routine earnings forecasts over which, it is argued, management have greater discretion.
Intra-Ring Properties of Earlywood and Latewood Sections of Sessile Oak (Quercus petraea) Wood

Strength attributes of isolated microscopic sections of earlywood (EW) and latewood (LW) tissues are evaluated for sessile oak (Quercus petraea). The properties measured at the micro-scale were then used to estimate the macroscopic strength characteristics of the wood. The bending strength, modulus of elasticity (MOE) in bending, and tensile strength of EW and LW sections were determined. The EW and LW ring width, annual ring width, and LW proportion were also determined. The estimated values were calculated using the EW and LW mechanical properties and LW proportions, while the measured values were determined using standard-sized test samples. The LW sections had higher values than the EW sections for all measured mechanical properties. The average EW and LW widths and LW proportion were 0.50 mm, 0.49 mm, and 49.3%, respectively. The estimated bending strength, MOE, and tensile strength values were 80.1 MPa, 2831.7 MPa, and 112.1 MPa, respectively. The estimated bending strength and MOE values were lower than the measured values, while the estimated tensile strength values were higher than the measured values.
Changes in Aggression of 13-17 year-old Adolescents after Intervention Based on Cognitive-behavioural Therapy

This article discusses how intervention based on cognitive behaviour therapy affects aggression. In this research, 13 to 17 year-old high school pupils were divided into two groups: the experimental group which participated in the training and the control group which did not. Research results have revealed that after the intervention based on cognitive-behavioural therapy the numbers of male and female physical and verbal aggression decreased. However, no such changes were observed in the control group. Moreover, after the intervention based on cognitive-behavioural therapy, the numbers of male and female hostility decreased in both groups. Female numbers of anger decreased after the intervention based on cognitive-behavioural therapy. However, the numbers of aggression in the control group and the numbers of male aggression in the experimental group have not changed. DOI: http://dx.doi. org/10.5755/j01.ss. 79.1. 4074
Factors effecting hamstrings to quadriceps peak torque ratio in volleyball players

The aim of this study was to analyze of hamstring to quadriceps peak torque ratio (H:Q) measured in isokinetic testing with respect to different angular velocities (60, 180, 300°/s), gender, dominant side and mode of contraction (concentric, eccentric) in volleyball players. Twenty male and ten female healthy volleyball players participated in this study. An independent t-test was used to compare the differences between gender. One-way analysis of variance test was conducted to test for differences by effecting factors. There was a statistically significant difference between dominant and non-dominant side in H:Q ratio at 300°/s in males (p 0.05). There was no statistically significant difference between at 60-180-300°/s velocities by Hconc:Qconc contractions and at 60°/s by Hconc:Qecc contractions for male and female’s peak torques in dominant side (p>0.05). There was a statistically significant difference between at 60°/s by Hconc:Qconc and Hconc:Qecc contractions for male and female’s peak torques in dominant side (p 0.05). It was found in our study that H:Q ratio increases with increasing angular velocity. The findings of the present study indicated that angular velocity, type of contraction and leg dominance influence isokinetic strength profiles of male and female, consequently, muscular balance that is H:Q at the knee. This implies that isokinetic concentric knee strength plays more role in high intensity contractions and has more effect at high velocities of contraction in maximal performance.
Foliar iron application on growth and yield of tomato

Fertilizers provides important nutrients for plants growth and production. One of micronutrient needed is Iron (Fe) which plays an important role in various enzymatic activities. Research on Fe fertilization in tomato is rarely done due to the low Fe requirement. This study was conducted to investigate the application of Fe on tomatoes’ growth and production. The experiment used tomato ‘Permata’ variety, and was designed as completely randomized design with 2 factors. The fist factor was frequency of ferrous sulphate (FeSO4) spraying (1 and 2 times spraying after transplanting). The second factor was FeSO4 concentration: 0.25, 0.5, 0.75, and 1% with six replications. The observation covered plant height, number of leaves, chlorophyll content, amount and weight of fruit per plant in the third harvest. Plant height and number of leaves at 54 days were not different in all treatments with an average height of 123-155 cm and 27-39 strands of leaves. The chlorophyll content ranged between 0.89-1.24 mg g−1 of fresh weight. Application of FeSO4 influenced number and weight of fruit. Application of 1% FeSO4 spraying twice at 15 and 30 days after transplanting produced the highest number and weight of fruit until the third harvest.
Determinants of Financial Sustainability of Microfinance Institutions in Bangladesh

Microfinance is a type of banking service that is provided to unemployed or low-income individuals or groups who have no alternative source to gain financial support. Ultimately, the goal of microfinance is to give low income peoples an opportunity to become self-sufficient for their entrepreneurship development. This study investigates the performances of financial self-sustainability of microfinance institutions and compared their positions in Bangladesh. The multiple regression technique is used to measured financial self-sustainability to justify with yield on gross loan portfolio, cost per borrower and also average loan balance per borrower. The multiple regression output revealed that most of the microfinance institutions are financially self-sustainable to operate their operations in this region. However, this study is recommended for policy considerations of the successful and effective microfinance operation productivity and reduces of borrowing funds from the donars, reducing operation cost, generate financial revenue finally to increase of their total assets in Bangladesh.
Aggregate Unemployment Decreases Individual Returns to Education

On the basis of a theoretical model, we argue that higher aggregate unemployment affects individual returns to education. We therefore include aggregate unemployment and an interaction term between unemployment and the individual education level in a standard Mincer equation. Our results show that an increase in regional unemployment by 1% decreases the returns to education by 0.005 percentage points. This implies that higher skilled employees are better sheltered from labour market changes with respect to their jobs but encounter larger wage changes than less skilled employees. Differences in regional unemployment can in addition almost fully explain the observed large differences in regional returns to education. We use representative individual data and regional panel variation in unemployment between different German regions and for different employee groups. We demonstrate that our results are robust with respect to aggregation bias, time lags and potential endogeneity of the unemployment variable.

Estimation of debris cover and its temporal variation using optical satellite sensor data: a case study in Chenab basin, Himalaya

Debris cover over glaciers greatly affects their rate of ablation and is a sensitive indicator of glacier health. This study focuses on estimation of debris cover over Samudratapu glacier, Chenab basin, Himalaya, using optical remote-sensing data. Remote-sensing image data of IRS-1C LISS-III (September 2001), IRS-P6 AWiFS (September 2004) and Terra ASTER (September 2004) along with Survey of India topographical maps (1963) were used in the study. Supervised classification of topographically corrected reflectance image data was systematically conducted to map six land-cover classes in the glacier terrain: snow, ice, mixed ice and debris, debris, valley rock, and water. An accuracy assessment of the classification was conducted using the ASTER visible/near-infrared data as the reference. The overall accuracies of the glacier-cover maps were found to range from 83.7% to 89.1 %, whereas the individual class accuracy of debris-cover mapping was found to range from 82% to 95%. This shows that supervised classification of topographically corrected reflectance data is effective for the extraction of debris cover. In addition, a comparative study of glacier-cover maps generated from remote-sensing data (supervised classification) of September 2001 and September 2004 and Survey of India topographical maps (1963) has highlighted the trends of glacier depletion and recession. The glacier snout receded by about 756 m from 1963 to 2004, and the total glacier area was reduced by 13.7 km 2 (from 110 km 2 in 1963). Further, glacier retreat is found to be accompanied by a decrease in mixed ice and debris and a marked increase in debris-cover area. The area covered by valley rock is found to increase, confirming an overall decrease in the glacier area. The results from this study demonstrate the applicability of optical remote-sensing data in monitoring glacier terrain, and particularly mapping debris-cover area.
Patents, Innovations and Economic Growth in Japan and South Korea: Evidence from Individual Country and Panel Data

This paper looks at the relationship between patents and economic growth in Japan and South Korea using both individual country and panel data. For the econometric estimation, we use annual data for 1963-2005. For Japan, we find that the logarithms of real GDP and the number of patents are cointegrated. For South Korea, we do find such evidence. For Japan, we find a two-way causality between the growth of real GDP and the growth of the number of patents. For panel data, we find that the logarithms of real GDP and the number of patents are cointegrated. We find some evidence that the growth of real GDP Granger causes the growth of the number of patents. However, we do not find any evidence of reverse causality.
Comparison of high latitude electron density profiles obtained with the GPS radio occultation technique and EISCAT measurements

To obtain a comprehensive view on high latitude processes by applying different observation techniques, the SIRCUS campaign was initiated in 2001/2002. This paper compares electron density profiles derived from CHAMP radio occultation data and those measured with the EISCAT facility. Since ionospheric profiling with the help of space-based received GPS is a relatively new technique, validations with established independent instruments are of crucial need. We present 28 profiling events for quasi-statistical analyses, which occurred during the SIRCUS campaigns and describe some of them in more detail. We found out that the majority of profile comparisons in electron density peak value and height, as well as in TEC, lie within the error ranges of the two methods. Differences in the ionospheric quantities do not necessarily occur when the locations of the occultation and of the radar site show considerable distances. Differences are more pronounced when the ionosphere is remarkably structured.
