Boundedness , a priori estimates and existence of solutions of nonlinear elliptic problems

Consider the semilinear elliptic system −∆u = f(x, u, v), −∆v = g(x, u, v), x ∈ Ω, complemented by the homogeneous Dirichlet boundary conditions or by the nonlinear boundary conditions: ∂νu = f̃(y, u, v), ∂νv = g̃(y, u, v), y ∈ ∂Ω, where Ω is a smooth bounded domain in R and ∂ν denotes the derivative with respect to the outer unit normal ν. In this thesis, we are mainly interested in regularity, boundedness and a priori estimates of very weak solutions of such elliptic systems. In the first part, we improve recent results of Y. Li [32] on L∞-regularity and a priori estimates for nonnegative very weak solutions of elliptic systems complemented by Dirichlet boundary conditions. The proof is based on an alternate-bootstrap procedure in the scale of weighted Lebesgue spaces. In the next part, we show that any positive very weak solution of elliptic problem complemented by the nonlinear boundary conditions belongs to L∞ provided the functions f, g, f̃ , g̃ satisfy suitable polynomial growth conditions. In addition, all positive solutions are uniformly bounded provided the right-hand sides are bounded in L. We also prove that our growth conditions are optimal. Finally, we show that our results remain true for problems involving nonlocal nonlinearities and we use our a priori estimates to prove existence of positive solutions.
The ‘ Greatest Ever ’ Coaching Outcome Project : Preliminary Findings

Headlines of our main findings:  Substantial correlations between different independent estimates of coaching outcome (between client & coach and between client & sponsor, but not between coach & sponsor)  The coaching relationship remains the best predictor of outcome  Only client self-efficacy correlates with client outcome – coach self-efficacy does not  Only small correlations between personality in terms of MBTI and the other variables above
Design and Performance of a Low Frequency Time and Frequency Dissemination Service

Synchronization in time and frequency between various geographically separated locations is critically important to a number of industries and applications. Examples include the wired and wireless telecommunication industry, transportation and shipping, banking and financial transactions, utilities and power delivery systems, computer networks, emergency services, and military and homeland security systems. Timing is also a critical component of the U.S. National Position, Navigation, and Timing (PNT) Architecture, the National Airspace System (NAS), and the Intelligent Transportation System (ITS). The Global Positioning System (GPS) has become the sole means in many instances for obtaining these crucial timing signals. GPS provides the necessary timing performance levels and there are a myriad of low-cost, single-purpose GPS receivers on the market. However, GPS, and in fact any Global Navigation Satellite System (GNSS) or Regional Navigation Satellite System (RNSS), is vulnerable to both intentional and unintentional interference, jamming, and spoofing resulting in a range of service degradation from complete outages to sporadic and unpredictable unavailability to incorrect information. To maintain accurate timing in a GPS-denied environment using radio signals, we focus on providing high-power, Low Frequency (LF) solutions. Because of its long propagation range, the ability to measure the arrival time of a pulsed signal with great accuracy, and a well-defined ground wave signal propagation path, an LF solution makes for an attractive terrestrial-based alternative to a low-power, highfrequency, satellite-based signal. Our paper discusses LF system concepts for providing an alternative precise time and frequency source. A preproduction transmitter has been developed and was installed and tested on-air using an existing LF transmission site. The accuracy of the transmitted signal was measured and evaluated. We outline our plans for setting up an R&D test bed for additional on-air testing and present estimated coverage predictions. We also discuss the development and production of our first generation LF timing receiver, which has been undergoing testing and evaluation using on-air signals since March 2011. A timing research and development company is providing independent testing and analysis. Available results demonstrate that our receiver performs to Stratum-1 levels and meets the International Telecommunication Union (ITU) requirements for Primary Reference Clocks (PRC) in telecommunication networks. We present test and measurement setup, results, and conclusions based on our work.
Investigating Teachers ' Corrective Feedback and Learners ' Uptake in the EFL Classrooms

The aim of this study was to investigate different types of corrective feedback (CF) including learner uptake moves in error treatment sequences occurring in the low intermediate EFL classes. The findings show that recast was the type of feedback which was mostly preferred by the EFL teacher, though it led to the lowest amount of repair. The findings of the current study showed that those CF types that were much more effective in eliciting repair, namely metalinguistic feedback, elicitation, repetition and explicit correction, rarely occurred in the EFL classrooms.
IDENTIFICATION OF PATHOTYPES OF XANTHOMONAS ORYZAE PV . ORYZAE CAUSING BACTERIAL BLIGHT OF RICE IN BANGLADESH

S. M. K. H. Chowdhury, I. H. Mian and M.A.I. Khan. 2013. Identification of pathotypes of Xanthomonas oryzae pv. oryzae causing bacterial blight of rice in Bangladesh. Bangladesh J. Plant Pathol. 29 (1&2):21-27. An investigation was conducted to identify pathotypes or races of Xanthomonas oryzae pv. oryzae causing bacterial blight of rice depending on the reaction patterns to a set of nine near-isogenic lines (NILs) or differentials. Ten isolates of X. oryzae pv. oryzae collected from different locations of Bangladesh were tested on the NILs namely IRBB2, IRBB4, IRBB5, IRBB7, IRBB10, IRBB11, IRBB13, IRBB14 and IRBB21 harboring the resistance genes Xa2, Xa4, xa5, Xa7, Xa10, Xa11, xa13, Xa14 and Xa21, respectively. The resistance frequency was maximal in IRBB21 followed by IRBB4, IRBB5 and IRBB7. Among the differentials (NILs), the resistance frequency was the lowest in IRBB13 followed by IRBB10, IRBB2, IRBB14 and IRBB11. Based on susceptibility of the differentials and virulence of the isolates in terms of lesion length and infection frequency the isolates were grouped into 8 different pathotypes or races. Of them three isolates (ISO3, ISO4 and ISO6) showed identical virulence on the differentials and they were grouped into pathotype 1. Other seven isolates were grouped into 7 different pathotypes (Pathotype 2 to 8). The most avirulent isolate was ISO-1 followed by ISO-5 and ISO-10. Only one differential, IRBB21 showed resistant reaction to all isolates whereas IRBB13 was susceptible to all isolates except ISO1. Key word: Xanthomonas oryzae pv. oryzae, pathotype, rice differential.
Connectivity analysis of the Habanero enhanced geothermal system

A realistic fracture model that adequately describes a fracture-stimulated reservoir is fundamental for subsequent flow and heat transfer analyses of the system. This paper describes a method to create such a model using seismic events recorded during the fracture stimulation process. The method is a Bayesian framework in the form of Markov Chain Monte Carlo (MCMC) simulation that effectively produces a fracture model conditioned by the seismic point cloud. The method is applied to Geodynamics’ Habanero reservoir in the Cooper Basin of South Australia and detailed connectivity analysis between Habanero 1 and 3 is reported. The freeware FracSim3D is used for the analyses.
THE RELATIONSHIP AMONG IRANIAN EFL TEACHERS ’ GENDER , CRITICAL THINKING AND THEIR TEACHING STYLES *

This study attempted to explore the relationship among Iranian EFL teachers‟ gender, critical thinking and their teaching styles. To fulfill this purpose, 238 Iranian EFL teachers (119 males and 119 females) teaching at different branches of Shokouh Language Institute across different cities and towns in Tehran and Alborz provinces were asked to fill out two questionnaires including the Critical Thinking Questionnaire and Teachers Teaching Style Inventory.The data derived from the aforementioned questionnaires was fed into SPSS. Afterwards, the collected data was analyzed through Pearson Correlation statistical procedures, the results of which revealed that there was a statistically significant relationship between Iranian EFL teachers‟ gender, critical thinking and their teaching styles. Moreover, the application of the independent sample t-tests indicated that there was not any statistically significant difference between Iranian EFL male and female teachers' critical thinking and their gender. However, a statistically significant was found between Iranian EFL teachers' teaching styles and their gender. The results of this study would help all involved in language teaching to better deal with teaching and learning issues. Educators must strive to pursue promising teaching strategies and styles in order to promote the learners‟ achievement levels.
Synthesis of Calcium Oxide Nanoparticles and Its Mortality Study on Fresh Water Fish Cyprinus

Calcium oxide (CaO) nanoparticle (NP) was synthesized by solution combustion method using urea as fuel. The CaO nanoparticle was characterized by X-ray diffraction (XRD), Scanning Electron Microscope (SEM) analysis and UV-absorption spectral studies. The average crystallite size was found to be ≈36nm and the band gap energy of CaO nanoparticle was 4.9 eV. The toxicity tests were performed on fresh water fish Cyprinus carpio for synthesized CaO NP at different concentrations ranging from 200 to 280 mg/L for 4 days. Bioassays were repeated three times and the data obtained were statistically evaluated using Finney’s Probit Analysis. Toxicity test performed revealed that LC50 value for Cyprinus carpio was 234.9mg/L with 95% of confidence limits for 226.819242. 624mg/L.
Extraction and characterization of mucilage in Ziziphus mauritiana Lam

The aim of this study was to characterize the mucilage from jujube. Extraction conditions of the highest mucilage yield can derive from the following process: incubating jujube for 9 days, mixing jujube pulp with water in ratio of 1:7 at water temperature of 60°C, and precipitating the mucilage solution with ethanol in ratio of 1:3. Functional properties analysis of mucilage powder showed that it had brightness in similar value with xanthan gum but higher than guar gum. Water holding capacity was 11.77 g dry weight. The values of oil absorption were 9 and 6 times higher than guar gum and xanthan gum, respectively. Emulsion capacity was analogous to that of guar gum but less than xanthan gum. Rheological properties of mucilage solution exhibited pseudoplastic as same as guar gum. This research also examined that higher concentration of mucilage solution caused larger values of viscosity, but increasing the pH and temperature led to the decrease of viscosity.

Comparative study of the various performance of machine learning algorithms is done through graphical representation of the results.
Nonprobability Sampling and Twitter

Twitter data are widely used in the social sciences. The Twitter Application Programming Interface (API) allows researchers to build large databases of user activity efficiently. Despite the potential of Twitter as a data source, less attention has been paid to issues of sampling, and in particular, the implications of different sampling strategies on overall data quality. This research proposes a set of conceptual distinctions between four types of populations that emerge when analyzing Twitter data and suggests sampling strategies that facilitate more comprehensive data collection from the Twitter API. Using three applications drawn from large databases of Twitter activity, this research also compares the results from the proposed sampling strategies, which provide defensible representations of the population of activity, to those collected with more frequently used hashtag samples. The results suggest that hashtag samples misrepresent important aspects of Twitter activity and may lead researchers to erroneous conclusions.
Investigation of in-vitro Anthelmintic Activity of Calamus leptospadix Griff . Shoot in Indian Adult Earthworm ( Pheretima posthuma )

Article history: Received on: 11/04/2013 Revised on: 09/05/2013 Accepted on: 05/06/2013 Available online: 27/06/2013 Calamus leptospadix Griff. (Arecaceae), is an important ethnomedicinal plant of Assam known as Lejaibet by the local Assamese community and is being wildly used by various communities in Assam. No detailed study or reports along with scientific evidence are available with this important plant. An exhaustive study was carried out with a view to substantiate the therapeutic potential of the plant in terms of its anthelmintic activity against Pheretima posthuma using Albendazole as a reference standard. 0.9% w/v of normal saline solution, 25mg/ml, 50mg/ml, 100mg/ml each of standard drug Albendazole and Methanolic, Ethanolic and Aqueous extracts of Calamus leptospadix Griff. were freshly prepared. Forty eight Indian Adult Earthworms were collected, divided into twelve groups containing four worms in each group. Time for paralysis and time for death were recorded for each group. All the three extracts with concentrations of 25mg/ml, 50mg/ml, 100mg/ml produced dosedependent paralysis. Methanolic extract of Calamus leptospadix Griff. gave shortest paralysis and death time at 100mg/ml as compared to that of standard and other two extracts. Results are expressed as Mean ± SEM (P< 0.05) of 4 worms in each group. From the investigation, conclusion can be drawn that Calamus leptospadix Griff. (Arecaceae) used by the people of Assam traditionally to treat intestinal worm infections, possesses significant anthelmintic activity.
Examining the Relationships between Self-Efficacy, Effort Regulation Strategy Use, and English Vocabulary Skills

This study explores the relationships among self-efficacy beliefs, effort regulation strategies, and English vocabulary development at a university in Japan. The theoretical framework draws on Pintrich and Zusho’s (2002) model of self-regulation, motivation, and academic success and Bandura’s (1986) social cognitive theory. Educational psychology literature indicates that self-efficacy beliefs predict selfregulation strategy use, and that self-efficacy beliefs and self-regulated learning are two of the most important predictors of a learner’s academic success (Bandura, 1986; Pintrich, 2004). Although a large number of studies have been conducted in general education, there has been limited research on this topic in the Japanese university English education context. In order to examine the relationships between learners’ self-efficacy beliefs, effort regulation strategy use, and English vocabulary skills, the present research focused on English majors at a Japanese university. Data were collected using a questionnaire including items that measured self-efficacy and effort regulation strategies, and Nation’s Vocabulary Size Test (2001). The data were analyzed employing structural equation modeling in order to highlight clear relationships among these variables. The results indicated that self-efficacy predicted effort regulation strategies use, which in turned influenced L2 vocabulary skills.
ENERGY DISTRIBUTION OF EJECTED PHOTOELECTRONS IN K-2 V PROCESS

In the last few years, a great deal of attention has been devoted to Double-Core-Hole states, and especially those involving K-shells, K states, as well as, KV states, which include simultaneous core ionization and core-excitation. In this paper we gave a theoretical framework that enables prediction of the energy electron distribution in KV process in linearly polarized laser field. In order to achieve this, we obtained a formula for the transition rate taking into account the channels of sequential, nonsequential and ionization with ionic core excitation. We started with the KV process in helium like atoms. We showed that inclusion of mentioned additional processes significantly influences the transition rate and, at the same time, the energy distribution of the ejected photoelectrons. This is related especially to the energy range of the ejected photoelectrons bringing us to the energy range of low energy electrons which has a significant role in biodamage.
Volatile flavour compounds of mangosteen juice and wine fermented with Saccharomyces cerevisiae

Mangosteen (Garcinia mangostana L.) is a popular tropical fruit known as “the queen of fruits”. This study investigated the volatile components of mangosteen before and after fermentation with Saccharomyces cerevisiae using HS-SPME-GC-MS/FID. Mangosteen wine was subjected to GC-olfactometry (GC-O) analysis. In total, 5 acids (C2-C10), 6 alcohols, 6 carbonyls (5 aldehydes, plus acetone), 10 esters and 5 terpenes were detected in the juice. After fermentation, while the respective number of acids and alcohols remained unchanged, only 2 carbonyls (aldehydes), 1 terpene (α-copaene) and now 20 esters were present in wine. (Z)-3-Hexen-1-ol, hexan-1-ol, hexanal and (E)-2-hexenal were the main volatiles in the juice. Besides ethanol, the compounds isoamyl alcohol, 2-phenylethyl alcohol, ethyl decanoate and ethyl octanoate were the major volatiles in the wine. GC-O CharmAnalysisTM revealed the key aroma-active compounds in the wine as isoamyl alcohol (flavour dilution value, FDV, 729), 2-phenylethyl alcohol (FDV, 81) and isoamyl acetate (FDV, 27), together with first-time reported longifolene (FDV, 9).
3 THE OPTIMIZATION BETWEEN TAMDAR DATA ASSIMILATION METHODS AND MODEL CONFIGURATION IN MM 5 AND WRF-ARW

Lower and middle-tropospheric observations are disproportionately sparse, both temporally and geographically, when compared to surface observations. The unsubstantial density of observations is likely one of the largest limiting factors in numerical weather prediction. Atmospheric measurements performed by the Tropospheric Airborne Meteorological Data Reporting (TAMDAR) sensor of humidity, pressure, temperature, winds aloft, icing, and turbulence, along with the corresponding location, time, and altitude from built-in GPS are relayed via satellite in real-time to a groundbased network operations center. Since December 2004, the TAMDAR sensors have been operating on a fleet of 63 Saab 340s operated by Mesaba Airlines in the Great Lakes region as a part of the NASA-sponsored Great Lakes Fleet Experiment (GLFE). This fleet was the primary source of data for the study presented in Jacobs et al. (2007, 2008). An example of the flight data density for a typical day in May 2007 is shown in Fig. 1, which is essentially the same density as 2006 (with Mesaba). Equipage of sensors on additional aircraft across the continental US and Alaska is currently underway. An example of the increase in observations and flights can be seen for the same day in May of 2008 (cf. Fig. 1 and Fig. 2).
Evaluation of Various Proposed Lateral Load Patterns for Seismic Design of Steel Moment Resisting Frames

The seismic design of buildings is normally based on the equivalent lateral forces provided in seismic design guidelines. The height-wise distribution of these lateral design loads predominantly correspond to the first vibration mode. However, as structures exceed their elastic limits in severe earthquakes, these load patterns may not represent the nonlinear response, and therefore they would not necessarily lead to efficient distribution of strength within the structure. A brief review of alternative lateral load patterns resulting from investigations on nonlinear seismic response of structures is presented. Due to the limits caused by idealizations and simplifications inherent in such investigations, the practicality and accuracy of the proposed load patterns should be evaluated and verified before proceeding into the practice. This paper examines the efficiency of various patterns for seismic design of 5 and 10-storey SMRFs. The nonlinear response and seismic performance of these models are studied under five different seismic records.
Comparison of CPTu and SDMT after 2012 Samara Earthquake , Costa Rica : liquefaction case studies

On September 5, 2012, a strong Mw = 7.6 earthquake hit Costa Rica. Its epicenter was located 10 km south of Samara, Guanacaste (offshore). This motion induced several geotechnical effects such as landslides, liquefaction, lateral spreading and local amplification. Of particular interest to the present paper was the occurrence of lateral spreading along several beaches located nearby the epicenter. The authors considered this a valuable opportunity to better understand this type of geotechnical phenomena. Contacts were made with the local governments in order to get access permits to two public beaches (Ostional and Garza). CPTu, SDMT, and disturbed sampling were carried out in order to gain an understanding of the geotechnical conditions that favored the occurrence of liquefaction. The aim of this paper is to use the latest methods for evaluating liquefaction potential based on SDMT and CPTu to back predict the observed phenomena and consequences. The main idea is to compare CPTu and SDMT as predictors of liquefaction for specific case studies.
