Streamers and adjacent regions observed by UVCS/SOHO: A comparison between different phases of solar activity

UVCS/SOHO observations of the $\ion{O}{vi}$ resonance doublet and $\ion{H}{i}$ Ly α line intensities and profiles, together with measurements of the visible linearly polarized radiance, have been performed during two MEDOC campaigns in 1997 and 2000, i.e. near solar minimum and approaching the solar maximum phase, respectively. During both observational runs mid-latitude coronal regions in the West limb of the Sun have been scanned over a range of heliocentric distance from 1.39 to 4.1 $R_{\odot}$, to study the plasma properties of streamers and adjacent regions, such as ion kinetic temperature, electron density and outflow velocity, paying particular attention to comparing plasma conditions deduced for different ions in coronal structures observed on different days and during different phases of solar activity. Besides confirming some previous findings on significant differences between open and closed field-line structures at solar minimum, our results provide some evidence for differences in kinetic temperature among mid-latitude solar minimum streamers observed on different days from about 2 $R_{\odot}$ outwards, as well as in their dynamical conditions at heliocentric distances greater than 3.6 $R_{\odot}$. For observations carried out in 2000, conversely, the mid-latitude coronal streamers and their surroundings are about 3 times, and more than one order of magnitude brighter, respectively, than their solar minimum counterparts and exhibit very similar kinetic and dynamical conditions. The kinetic temperatures in adjacent regions are higher than in streamers (by about a factor of 2) only within 2 $R_{\odot}$, while at greater heights such differences vanish, making it difficult to discriminate between open and closed structures. This is opposite to the behaviour detected at solar minimum, when adjacent regions appear to be characterized by kinetic temperatures progressively higher and higher than in streamers with increasing height, from 2 $R_{\odot}$ outwards. Therefore, a clear characterization of open and closed configurations near the solar maximum might be quite difficult, probably due both to the intrisically more complex magnetic configuration of the corona in this phase of the solar activity and the line-of-sight contamination effects that in a highly structured solar corona may strongly mix background and foreground plasma with different properties. The transition from the solar minimum to maximum also seems characterized by a global increase in the electron density inside streamers of about a factor of 4 at 1.7 $R_{\odot}$ and then it progressively decreases with height.

Effect of External Factor on Share Price Forecasting

The stock market can be thought of as a highly complex and adaptive system. Variation in share price of the stock market can be considered as an indicator of the economical trend of a country. Thus, forecasting the behaviour of the stock market is at primary concern not only of the business community but also of the policy markers of a country. The fluctuation of share prices of the stock market depend on external and internal factors. The major difficulty in this regards is that most of these factors cannot be quantified in a model. The results in this research clearly illustrates that the historical data with external input factor (such as the average exchange rate) increases the more accurate share price forecasting ability of the neural network model.
Salivary gland tumors: Molecular characterization and therapeutic advances for metastatic disease

Salivary gland cancers represent a rare group of tumors composed by over 20 histological subtypes. Initially treated as one single disease, its diagnosis, prognosis, and treatment are currently being stratified based on morphology. More recently, insight has been provided on the molecular characterization of each subtype, further improving diagnostic accuracy and paving the way for personalized therapy. In this article, we provide a comprehensive review of recent breakthroughs, preliminary results of novel therapy, and future directions on the treatment of these complex malignancies.
Chern-Simons Theory with Complex Gauge Group on Seifert Fibred 3-Manifolds

We consider Chern-Simons theory with complex gauge group and present a complete non-perturbative evaluation of the path integral (the partition function and certain expectation values of Wilson loops) on Seifert fibred 3-Manifolds. We use the method of Abelianisation. In certain cases the path integral can be seen to factorize neatly into holomorphic and anti-holomorphic parts. We obtain closed formulae of this factorization for the expectation values of torus knots.
Attitudes towards land use and development in the Mat-Su:

In communities that largely depend on the extraction of natural resources, attitudes towards conservation and development may seem at odds or particularly rigid. With an unprecedented wealth of natural capital, a growing mining sector, strong oil and gas industry, and a politically conservative population, Alaska serves as a case study to measure such attitudes. This research was motivated by a lack of primary ecosystem service valuation studies in Alaska that could be used to assess the public’s perceived value of ecosystem services in order to guide future land use decisions and incentivize land use decisions that minimize negative externalities. A choice experiment was conducted with 224 households in the Matanuska-Susitna Borough, the fastest growing region in Alaska and one of the fastest growing regions in the U.S. Rapid development with few restrictions has led to changes for local ecosystems particularly important to salmon, negative effects on access related to recreation and tourism, and caused conversion of valuable farmland. Study results show that attitudes and values vary regarding future land use and economic development efforts. On average, policy action to improve conditions for local salmon stocks are most valuable to local residents followed by protecting farm and ranch lands as well as public access to recreation sites. Conversely, residents show negative preferences towards rapid population growth and developing local mining, oil and gas, and timber resources but support developing a professional and technical services sector. The quantified welfare changes related to different development scenarios show that focusing on conserving valuable ecosystem services is in the public’s best interest.
Information security culture - validation of an assessment instrument

Organisations need to ensure that the interaction among people, as well as between people and information technology (IT) systems, contributes to the protection of information assets. Organisations therefore need to assess their employees’ behaviour and attitudes towards the protection of information assets in order to establish whether employee behaviour is an asset or a threat to the protection of information. One approach that organisations could use is to assess whether an acceptable level of information security culture has been inculcated in the organisation and, if not, take corrective action. The aim of this paper is to validate an information security culture assessment instrument. This is achieved by performing a factor and reliability analysis on the data from an information security culture assessment in a financial organisation. The results of the analysis are used to identify areas for improving the information security culture assessment instrument. The study makes a contribution to the existing body of knowledge concerned with the assessment of information security culture and its value for management to ensure the protection of information assets.
Risk Sharing in the Middle East and North Africa

This study investigates welfare gains and channels of risk sharing among 14 Middle Eastern and North African (MENA) countries, including the oil‐rich Gulf region and the resource‐scarce economies such as Egypt, Morocco and Tunisia. The results show that for the 1992–2009 period, the overall welfare gains across MENA countries were higher than those documented for the Organization for Economic Cooperation and Development (OECD) nations. In the Gulf region, the amount of factor income smoothing does not differ considerably when output shocks are longer lasting rather than transitory, whereas the amount smoothed by savings increases remarkably when shocks are longer lasting. In contrast, both factor income flows and international transfers respond more to permanent shocks than to transitory shocks in the non‐oil MENA countries. The results also show that a significant portion of shocks is smoothed via remittance transfers in the economically less‐developed MENA countries, but not in the oil‐rich Gulf and OECD countries. Finally, for the overall MENA region, a large part of the shock remains unsmoothed, suggesting that more market integration is needed to remedy the weak link of incomplete risk sharing.
A Survey of Performance Evaluation and Control for Self-Similar Network Traffic

This paper surveys techniques for the recognition and treatment of self-similar network or internetwork traffic. Various researchers have reported traffic measurements that demonstrate considerable burstiness on a range of time scales with properties of self-similarity. Rapid technological development has widened the scope of network and Internet applications and, in turn, increased traffic volume. The exponential growth of the number of servers, as well as the number of users, causes Internet performance to be problematic as a result of the significant impact that long-range dependent traffic has on buffer requirements. Consequently, accurate and reliable measurement, analysis and control of Internet traffic are vital. The most significant techniques for performance evaluation include theoretical analysis, simulation, and empirical study based on measurement. In this research, we discuss existing and recent developments in performance evaluation and control tools used in network traffic engineering.

Shared Mental Models of Challenging Maritime Situations: Comparisons of Ship and Shore Personnel in the Straits of Malacca and Singapore

Shared mental models, measured as similar perceptions and understandings of the components of a work task or an operative environment, is a key characteristic for high performing teams. Identifying and addressing differences in mental models may help enhance teamwork, and can serve as a frame for the improvement of human‐centered information and communication systems. This paper has been written as part of the SESAME Straits project, a testbed within the e‐Navigation framework. It examines similarities and differences in mental models between Deck Officers working aboard ships and Vessel Traffic Service Officers working ashore. Data was compared the participants ́ perception of 12 challenging traffic situations in the Straits of Malacca and Singapore. A total of 189 respondents participated by means of an electronic survey. Findings show that Deck and Vessel Traffic Officers do have a large degree of shared mental models, but that there also are significant differences. In particular, there are large ship‐shore differences in perceptions of the impact on local ship traffic on safety and efficiency. The second and third situation of large difference was delayed or reduced availability of port services, and challenging weather conditions. Implications are that future development of ship‐shore collaborative systems should specifically explore and address the issue of local ship traffic, and to find ways to integrate information about availability and timing of port services and of difficult weather situations. http://www.transnav. eu the International Journal on Marine Navigation and Safety of Sea Transportation Volume 11
The Superintendent and School Improvement: Antecedents, Actions and Outcomes.

Employing multiple case study analysis methods, the attitudes and actions of superintendents in three school districts with improving basic skills test performance were compared with those of superintendents of three nonimproving districts to determine if patterns of difference existed. Contextual variations and superintendents' priorities were explored as antecedents to actions and outcomes. Four contextual variables were identified as potentially relevant to superintendent behavior, including superintendent and principal tenure, community climate, grade configuration and dispersion of attendance centers, and district financial condition. Superintendent's actions were classified under the nine control functions identified by Murphy and associates: supervision, selection, socialization, evaluation, rewards and sanctions, goals, resource allocation, monitoring, and behavior control. In improving districts, there was greater principal awareness of superintendents' goals and priorities; greater evidence of shared superintendent-principal control; a higher priority for teacher evaluation and/or supervision; and more attention paid to analyzing test results. Caution is needed in adopting a single set of practices at the district level to improve student outcomes. Comparisons of test and nontest indicators of student outcomes in the six districts illustrated the complexity and ambiguity of classifying districts as improving or nonimproving on the basis of multiple outcome or single indicators.

Male Involvement in Family Planning and Associated Factors among Marriedin Malegedo Town West Shoa Zone, Oromia, Ethiopia

Background:- Men are not only act as decision-makers for women and children’s access to health services, but also through abuse or neglect, men’s actions can have a direct bearing on the health of their female partners and children. Historically most reproductive health program focused on family planning and in turn, most family planning program offered their services exclusively to women but Influencing males’ attitude is critical to increase contraceptive prevalence in the society. The aim of this study was to determine married male involvement in family planning in Gedo Town. Results: - The complete response rate was 95%. Out of total respondents 94.9% were Oromo with the mean age of 40 years. From total study respondents about 54% respondents with 95%CI of (47.4 - 59.7%) had good knowledge. the prevalence of decision making power by both husband and wife together and current use of family planning with 95% CI were 40.8%(34.6-46) and 30.9%(24.9-36.4) respectively The prevalence of male involvement on family planning was 36% with 95% CI of (30-41.2) with independent predictor of discussion with partner (AOR= 5.18,), current use of family planning (AOR=2.82), informing partner or other to use contraceptive (AOR=3.36) and had information the presence of contraceptive for male (AOR=2.57) respectively. Methods:- A community based cross-sectional study design with quantitative data collection methods were employed from April 5 to April 15/2015. All households who were having married men in Gedo town were labelled and household number codes were given. The study participants were selected by using simple random sampling computer generated technique. Both bivariate and multivariate logistic regressions were used to identify associated factors. The results were presented by using tables, figures and narratives. Conclusion:- This study revealed the married male’s level of knowledge about modern family planning in Gedo town was very low; about half (46.0%) respondents have poor knowledge about modern family planning and more than have of the respondents which 70.1% of males hadn’t ever used contraceptives and males involvement in family planning were very low with the independent predictors of attending health education, discussion with partner about family planning, educational level and had information about male contraceptive respectively. Therefore, these factors would be emphatically considered during development of male Family planning and family reproductive programs by policy makers and health planners. Keywords: Male involvement, Family planning, Gedo, Ethiopia
Comparative assessment of plasmid DNA delivery by encapsulation within or adsorbed on poly (D, L-lactide-coglycolide) nanoparticles

Purpose : To compare the gene delivery effectiveness of plasmid DNA (pDNA) encapsulated within poly (D,L-lactide-co-glycolide) (PLGA) nanoparticles with that adsorbed on PLGA nanoparticles. Methods: PLGA nanoparticles were prepared using solvent-evaporation method. To encapsulate pDNA within the particles, it was first complexed with cetyltrimethylammonium bromide (CTAB) and then added to the oil phase during the synthesis. For the adsorption, PLGA nanoparticles were first modified with either CTAB or chitosan and then pDNA was adsorbed on the particle surface by electrostatic interaction. Results : Nanoparticles encapsulating pDNA exhibited better plasmid loading and protection with significantly lower burst release (p < 0.05) compared to that of the nanoparticles with adsorbed plasmid. Cell uptake of chitosan-modified nanoparticles by murine neuroblastoma (N2a) cells was significantly (p < 0.05) higher than that of chitosan-free nanoparticles. Nanoparticles encapsulating pDNA showed higher transfection efficiency (p < 0.05) in N2a cells. Conclusion : Encapsulation of pDNA within PLGA nanoparticles presents a potential strategy for gene delivery that is superior to pDNA adsorbed on the nanoparticle surface. In addition, encapsulation keeps the particle surface free for further modifications such as the addition of targeting ligands. Keywords : Poly (D,L-lactide-co-glycolide), Plasmid DNA, Encapsulation, Adsorption, Cellular uptake, Gene therapy, Targeting ligands
Synthesis of Fe3O4@silica core-shellparticles and their application for removal of copper ions from water

The main objective of this study was to synthesize an environmentally friendly nano-structural adsorbent. These nano magnetic particles can be applied to remove heavy metal ions from industrial wastewater because the surface of the particles is covered with SiO2, and the SiO2 is inactive and can adsorb heavy metal ions. Tests were then conducted to study the adsorption of Cu(II) ions onto Fe3O4@SiO2 from an aqueous solution for the effect of contact time, adsorbent dose, solution pH and concentration of metal ions in batch systems. The equilibrium data were analyzed using the Langmuir and Freundlich isotherm by nonlinear regression analysis and found that the adsorption isotherm data will better fit by Langmuir model. The maximum adsorption capacities of Cu (II) were 47 mg/g. Fe3O4@SiO2 was regenerated and found to be suitable for reuse in successive adsorption-desorption cycles 5 times without significant loss of adsorption capacity.
Grid Interfacing Three Phase Five-Level Inverter with Less Number of Switching Elements

Induction motors are widely used in industries, because they are rugged, reliable and economical and hence they are called as work horse power of industry. Induction motor drives requires suitable converters to get the required speed and torque without or negligible ripples. Multilevel inverters can do this job. But the conventional MLIs such as Diode Clamped MLIs requires extra diodes in conjunction with the active switches, Flying capacitor MLIs requires extra Capacitors and control also difficult if the levels increases and the Cascaded H-bridge MLIs requires separate dc sources which limits its use. This paper proposes a new type of multi level Inverter employing PWM technique which converts the dc into ac using less number of switches when compared to conventional multilevel Inverters. Finally the induction motor using proposed inverter is simulated using Matlab/Simulink environment and the corresponding results are presented in this paper.
A Limit Theorem for the Six-length of Random Functional Graphs with a Fixed Degree Sequence

We obtain results on the limiting distribution of the six-length of a random functional graph, also called a functional digraph or random mapping, with given in-degree sequence. The six-length of a vertex $v\in V$ is defined from the associated mapping, $f:V\to V$, to be the maximum $i\in V$ such that the elements $v, f(v), \ldots, f^{i-1}(v)$ are all distinct. This has relevance to the study of algorithms for integer factorisation.
HO2NO2 and HNO3 in the coastal Antarctic winter night: a “lab-in-the-field” experiment

Observations of peroxynitric acid (HO2NO2) and nitric acid (HNO3) were made during a 4 month period of Antarctic winter darkness at the coastal Antarctic research station, Halley. Mixing ratios of HNO3 ranged from instrumental detection limits to ∼ 8 parts per trillion by volume (pptv), and of HO2NO2 from detection limits to ∼ 5 pptv; the average ratio of HNO3 : HO2NO2 was 2.0(± 0.6) : 1, with HNO3 always present at greater mixing ratios than HO2NO2 during the winter darkness. An extremely strong association existed for the entire measurement period between mixing ratios of the respective trace gases and temperature: for HO2NO2, R 2 = 0.72, and for HNO3, R 2 = 0.70. We focus on three cases with considerable variation in temperature, where wind speeds were low and constant, such that, with the lack of photochemistry, changes in mixing ratio were likely to be driven by physical mechanisms alone. We derived enthalpies of adsorption (1Hads) for these three cases. The average1Hads for HNO3 was−42± 2 kJ mol −1 and for HO2NO2 was −56± 1 kJ mol ; these values are extremely close to those derived in laboratory studies. This exercise demonstrates (i) that adsorption to/desorption from the snow pack should be taken into account when addressing budgets of boundary layer HO2NO2 and HNO3 at any snow-covered site, and (ii) that Antarctic winter can be used as a natural “laboratory in the field” for testing data on physical exchange mechanisms.
