Multi-wavelength study of coronal waves associated with the CME-flare event of 3 November 2003

The large flare/CME event that occurred close to the west solar limb on 3 November 2003 launched a large-amplitude large-scale coronal wave that was observed in H α and Fe xii 195 A spectral lines, as well as in the soft X-ray and radio wavelength ranges. The wave also excited a complex decimeter-to-hectometer type II radio burst, revealing the formation of coronal shock(s). The back-extrapolation of the motion of coronal wave signatures and the type II burst sources distinctly marks the impulsive phase of the flare (the hard X-ray peak, drifting microwave burst, and the highest type III burst activity), favoring a flare-ignited wave scenario. On the other hand, comparison of the kinematics of the CME expansion with the propagation of the optical wave signatures and type II burst sources shows a severe discrepancy in the CME-driven scenario. However, the CME is quite likely associated with the formation of an upper-coronal shock revealed by the decameter-hectometer type II burst. Finally, some six minutes after the launch of the first coronal wave, another coronal disturbance was launched, exciting an independent (weak) decimeter-meter range type II burst. The back-extrapolation of this radio emission marks the revival of the hard X-ray burst, and since there was no CME counterpart, it was clearly ignited by the new energy release in the flare.

Wideband Bandstop Filter Based on Capacitively Coupled λ/4 Short-Circuited Lines

A new wideband bandstop filter(BSF) with a sharp roll-off characteristic is introduced in a stripline structure in this paper. The BSF consists of two sections: the first is two capacitively coupled λ/4 short-circuited lines with opposite ground positions, while the second is a capacitively coupled λ/4 short-circuited line. The BSF provides three transmission zeros within the stopband and better than 22 ㏈ rejection over the whole wireless local area network (WLAN) band from 5.15 to 5.825 ㎓. The BSF, cascaded to an U.S. ultra-wideband(UWB: 3.1~10.6 ㎓) bandpass filter(BPF), is simulated with HFSS and realized with low-temperature co-fired ceramic(LTCC) green tape with a dielectric constant of 7.8. The measurement results agree well with the HFSS simulation results. The size of the UWB BPF including the BSF is 3×6.3×0.45 ㎣.

Do rainfall conditions push or pull rural migrants: evidence from Malawi

This article uses nationally representative data from Malawi's 2004/05 Integrated Household Survey (IHS2) to examine whether rainfall conditions influence a rural worker's decision to make a long-term move to an urban or another rural area. Results of a Full Information Maximum Likelihood regression model reveal that (1) rainfall shocks have a negative association with rural out-migration, (2) migrants choose to move to communities where rainfall variability and drought probability are lower, and (3) rainfall shocks have larger negative effects on the consumption of recent migrants than on the consumption of long-time residents.
Online partial discharges localization system

In this paper the design and construction of an online non-invasive noninvasive partial discharges (PD) localization system is presented; it is integrated by four equal discone antennas with a wideband of 30 MHz to 1.2 GHz and a central frequency of 615 MHz connected to a four-channel high-resolution digital oscilloscope. The obtained electromagnetic signals are processed in a personal computer using Wavelet Transform and Fast Fourier Transform (FFT) to reduce electromagnetic noise and identify the source of the PD respectively. Additionally, a spherical algorithm for spatial localization in R3 is used. High-voltage laboratory and in situ measurements are reported.
Dietary Methionine Restriction Reduces Inflammation Independent of FGF21 Action

Methionine restriction (MR) decreases inflammation and improves markers of metabolic disease in rodents. MR also increases hepatic and circulating concentrations of fibroblast growth factor 21 (FGF21). Emerging evidence has suggested that FGF21 exerts anti‐inflammatory effects. The purpose of this study was to determine the role of FGF21 in mediating the MR‐induced reduction in inflammation.
Castasterone regulated polyphenolic metabolism and photosynthetic system in Brassica juncea plants under copper stress

Cu is a micronutrient required for normal growth and development, but in excess amounts it became toxic. The present study investigated the effect of castasterone on regulation of polyphenolic metabolism and photosynthetic system along with effect on morphology of Brassica juncea plants under copper stress. Four concentrations of copper (0, 0.25, 0.50 and 0.75 mM) were used with or without castasterone. Copper treated plants significantly decreased the growth, biomass and photosynthetic pigments and photosynthetic characteristics. The copper toxicity also affected the total phenolic content, activity of polyphenol oxidase and caused variation in polyphenolic content. Application of castasterone significantly alleviated copper toxicity showing improvement in growth, biomass and photosynthetic systems. The activity of polyphenol oxidase and total phenolic content enhanced with castasterone supplementation, which improved the antioxidant potential of plants. These results showed that supplementation of castasterone can be useful for the enhancement of growth and biomass of plants growing in copper contaminated soils.
Riboswitches as Potential Targets for Aminoglycosides Compared with rRNA Molecules: In Silico Study

Riboswitches are cis acting riboregulaters in non-coding region of the mRNAs. Their possible contribution in antibiotic targeting especially for FMN, TPP and lysine riboswitches in bacteria has been revealed since a decade ago. Regarding some studies on the possibility of the interaction between aminoglycosides and the artificial riboswitches, in this study we attempted to evaluate the binding potential of different types of aminoglycosides including gentamicin, amikacin, kanamycin, neomycin, tobramaycin, sisomicin and paromomycin with various classes of riboswitches using computational methods. Applying Auto Dock vina, it was shown that the binding energy of each kind of riboswitches with different types of aminoglycosides (riboswitches/aminoglycosides) is almost similar or sometimes more than the binding energy of the aminoglycoside with the corresponding binding cage of “16S rRNA A site” (16S rRNA A site/aminoglycosides) as aminoglycosides’ target site. The affinity between riboswitches and aminoglycosides is almost the same or higher than the affinity of riboswitches/natural ligands. In this study ampicillin was used as the negative control antibiotic and 5S rRNA was employed as the negative control RNA. Results showed that the binding energies of riboswitches/ampicillin and 5S rRNA/aminoglycosides are usually lower than the energy of riboswitches/aminoglycosides. Accordingly, lysine, glycine and SAM-I riboswitches were recognized as the best RNA targets for all of the aminoglycosides because of their higher binding energy. In the next step, docking results were further validated by rDock program. Furthermore, it was shown that hydrogen binding makes a key role in the binding energy between aminoglycosides and riboswitches. Moreover, MD simulation studies on lysine riboswitch/paromomycin complex confirmed the stability of the docked structure in the solvent containing magnesium and chloride ions.
PISA and TIMSS Science Score, Which Clock is More Accurate to Indicate National Science and Technology

In 2015, PISA and TIMSS are coming up to us together. In this study, the data from PISA and TIMSS are used to investigate that which one is a better indicator of national science and technology (S&T) competitiveness? Number of S & T journal articles (per million people) is used as a measure to represent the national S&T competitiveness. Average IQ of the population, research and development (R&D) expenditure (% of GDP) and number of R&D researchers and technicians which affect the national competitiveness in S&T were also investigated. The study shows that PISA science scores would more significantly indicate national S&T competitiveness than TIMSS. Moreover, the study also shows a strong link between competence in S&T and IQ, research and development expenditure (% of GDP) or number of research and development researchers and technicians. Some possible micro-foundations of these relationships are discussed, and policy implication is clear.

Snoring Sound and Sleep Analysis in an Obese Patient Group

Objectives: Snoring is the most common symptom of obstructive sleep apnea syndrom (OSAS). In this study, snoring percentage and severity were determined in a group of obese patients (with a BMI ⩾30 kg/m2) and the relationship between OSAS severity and snoring intensity were investigated. Methods: A total of 60 obese patients were retrospectively included in the study with a complete polysomnography (PSG) examination and snoring sound analysis which was performed simultaneously with the sleep study. The participants were divided into three groups according to AHI scores. The percentages of snoring sounds above 65 and 85 dB, determined during sleep were compared between groups. The demographic data, PSG record and snoring percentage of the patients were compared statistically. Results: The intensity of snoring sound and the percentages of snoring sound above 65 and 85 dB were found to be significantly related with the disease severity of OSAS in the obese patients (P<0.05). Conclusion: In this study, the significant relationship between OSAS severity and snoring sounds percentages over 65 and 85 Db in obese patients was demonstrated. These findings are promising for further studies and clinical use.
Suppression method of partial-discharge interference signal based on the combination of morphological filters and complex wavelet transform

Solving the periodic narrowband interference and suppression of white noise during the actual detection of partial discharge (PD) are difficult. In this paper, a method of suppressing the interference signal method based on the combination of morphological filters and complex wavelet transform is proposed. Generalized morphological filters based on the principle of mathematical morphology were structured and set as a pre-filter unit to realize pre-treatment of the original PD signals, and complex wavelet transform was then employed to process the PD signals. Finally, denoised PD signals were obtained. Applying this method to deal with the noise in the simulation and acquisition of PD signals, the results showed that the method can restrain effectively the PD periodic narrowband interference and white noise. Compared with the same wavelet base of the wavelet and the complex wavelet denoising methods, this method reduces energy loss and retains well the PD signals characteristics.

BIM Coordination Room Layout: Assessment Criteria and Metrics

Coordination of BIM-based projects requires distinct media from those used for paper-based analysis. Participants of BIM coordination meetings have new needs as visualizing, navigating or checking 3D models. The objective of this paper is to present criteria and metrics for assessing the quality of BIM Room layouts. Fourteen different layouts were analyzed and evaluated for validating the results on metrics and criteria relating to physical layouts. In order to establish the relative importance of all proposed criteria for fulfilling the needs of BIM meeting participants, as well as the relative scores for the metrics, the AHP multi-criteria decision method based on analysis of comparisons in pairs was applied. The criteria and metrics presented and the methodology to measure them can be useful for evaluation of other rooms and layouts, supporting the design of more appropriate facilities for attending users of project meeting rooms based on BIM.

Operation of Direct Drive Systems: Experiments in Peak Power Tracking and Multi-Thruster Control

Direct-drive power and propulsion systems have the potential to significantly reduce the mass of high-power solar electric propulsion spacecraft, among other advantages. Recent experimental direct-drive work has significantly mitigated or retired the technical risks associated with single-thruster operation, so attention is now moving toward systems-level areas of interest. One of those areas is the use of a Hall thruster system as a peak power tracker to fully use the available power from a solar array. A simple and elegant control based on the incremental conductance method, enhanced by combining it with the unique properties of Hall thruster systems, is derived here and it is shown to track peak solar array power very well. Another area of interest is multi-thruster operation and control. Dualthruster operation was investigated in a parallel electrical configuration, with both thrusters operating from discharge power provided by a single solar array. Startup and shutdown sequences are discussed, and it is shown that multi-thruster operation and control is as simple as for a single thruster. Some system architectures require operation of multiple cathodes while they are electrically connected together. Four different methods to control the discharge current emitted by individual cathodes in this configuration are investigated, with cathode flow rate control appearing to be advantageous. Dual-parallel thruster operation with equal cathode current sharing at total powers up to 10 kW is presented.
Novel Design of UWB Band-Stop Filter (BSF) Based on Koch Fractal Structures

─ In this paper, a novel design of compact microstrip Ultra-Wideband (UWB) BandStop Filter (BSF) for wireless applications is proposed. The proposed BSF structure is based on Koch fractal geometry where its third iteration operates over a very wide bandwidth and improves the impedance matching. The microstrip filter configuration consists of a transmission line with pairs of Koch fractal Radial Stubs Loaded Resonators (RSLRs), and a modified ground plane with triple modified Defected Ground Structures (DGSs). Operation frequencies of the filter can be easily controlled by changing the iteration of embedded fractal structure. The DGS slots evolved from Photonic Band Gap (PBG) is embedded to achieve a good impedance matching and the required filter’s characteristics. The proposed BSF has a flat rejected-band characteristic around of 3.1-10.6 GHz with an insertion loss which is larger than 45 dB and a return loss less than 0.5 dB at the centre of the band-stop frequency range. An excellent agreement between measured and simulated was obtained. The proposed microstrip filter is fabricated on a Rogers RT/Duroid 5880 substrate with a relative dielectric constant of 2.2 and has a small size of 10×15×0.635 mm3. The proposed filter configuration is and can be integrated into any UWB system. Index Terms ─ Band-stop filter, DGS, Koch fractal, UWB application.
Meat quality of lambs fed on palm kernel meal, a by-product of biodiesel production.

This study aimed to establish the optimum level of palm kernel meal in the diet of Santa Ines lambs based on the sensorial characteristics and fatty acid profile of the meat. We used 32 lambs with a starting age of 4 to 6 months and mean weight of 22 ±2.75 kg, kept in individual stalls. The animals were fed with Tifton-85 hay and a concentrate mixed with 0.0, 6.5, 13.0 or 19.5% of palm kernel meal based on the dry mass of the complete diet. These levels formed the treatments. Confinement lasted 80 days and on the last day the animals were fasted and slaughtered. After slaughter, carcasses were weighed and sectioned longitudinally, along the median line, into two antimeres. Half-carcasses were then sliced between the 12th and 13th ribs to collect the loin (longissimus dorsi), which was used to determine the sensorial characteristics and fatty acid profile of the meat. For sensorial evaluation, samples of meat were given to 54 judges who evaluated the tenderness, juiciness, appearance, aroma and flavor of the meat using a hedonic scale. Fatty acids were determined by gas chromatography. The addition of palm kernel meal to the diet had no effect on the sensorial characteristics of meat juiciness, appearance, aroma or flavor. However, tenderness showed a quadratic relationship with the addition of the meal to the diet. The concentration of fatty acids C12:0, C14:0 and C16:0 increased with the addition of palm kernel meal, as did the sum of medium-chain fatty acids and the atherogenicity index. Up to of 19.5% of the diet of Santa Ines lambs can be made up of palm kernel meal without causing significant changes in sensorial characteristics. However, the fatty acid profile of the meat was altered. (Key Words : By-products, Fatty Acids, Organoleptic, Palmist, Ruminants)
Media Independence and Trust in NGOs

Why do levels of public trust in NGOs vary across postcommunist countries? How does media independence influence these trust levels? The authors begin from the premise that citizens develop trust in NGOs when they believe that NGOs function according to their normative expectations and they receive regular information about NGOs’ activities. Media has a crucial role in both these regards, especially in the context of countries in Eastern Europe and the former Soviet Union, where the NGO sector is in a nascent stage and citizens lack prior experiences with NGOs as activist organizations and providers of public goods and services. First, media can provide information about NGO activities that enables citizens to develop opinions about individual NGOs and NGOs as a category of social actors. Second, media can serve as a vehicle to monitor the activities of NGOs and make them accountable. However, media may have its own biases and provide misleading information about NGOs. Thus the authors expect that media independence is associated with trust in NGOs. They analyze the relationship between NGO trust and media independence using a time-series and cross-section panel of 28 postcommunist countries from 1997 to 2006, controlling for a range of domestic and international factors that might influence trust in the NGO sector. Our analysis suggests that independent media is positively associated with trust in NGOs.
Preserving of intercostobrachial nerve relieves breast carcinoma patients from postmastectomy pain syndrome

Background: Post-mastectomy pain syndrome (PMPS) is a complication experienced by majority of the patients who undergo breast surgery for cancer. The etiology of this chronic neuropathic pain syndrome seems to be complex and it is still understood below par. Injury to the intercostobrachial (ICB) nerve is presumed to be the dominant one for developing PMPS. This prospective study was designed to appraise the effect of preservation of intercostobrachial nerve on post-mastectomy pain syndrome and also to determine the most common anatomical variation of the intercostobrachial nerve during surgery. Methods: A total of 100 patients were included in this study and were divided into 2 groups. Group A included patients with ICB nerve preserved and Group B patients with ICB nerve sectioned. The patients were evaluated for pain subjectively on the 2 nd day, 1 month and in the 3 rd month post-operatively by short form of McGill pain questionnaire and visual analog scale. During surgical dissection, anatomical variation of ICB nerve was ascertained each time. Results: After 3 months, 68.2% of the patients were asymptomatic in Group A (ICB nerve preservation group) and 31.8% in the Group B (nerve section group) (chi-square test was applied and p value was 0.002). We found that type 1 anatomical variation was commonest with 87%. Conclusions: Preservation of ICB nerve might greatly decrease the incidence of PMPS. Hence, the insight of the anatomical variations of this nerve is very crucial for the operating surgeons to preserve them and to prevent PMPS.
