The mineralized fracture system that underlay paleo-fumarole field at Chinkuashih, Taiwan has been exposed by copper–gold mining to depths of about 550 m below the paleo-surface. Its mineralogy and systematic variations in metal and semimetal (Fe, Cu, As, Sb, Bi, Hg, Cd, Sn, Zn, Pb, Se, Te, Au, Ag) concentrations provide insights into the chemical responses of a magmatic-vapor phase as it expands through fracture arrays to the surface and discharges as fumaroles associated with more extensive solfatara. At Chinkuashih, following initial sealing of the fractures by silica-alunite alteration, brittle failure reestablished discharge from an underlying reservoir of magmatic vapor. Crystalline pyrite was deposited first in the fractures and was succeeded and replaced by 'enargite' (Cu3(As,Sb)S4) as sulfosalt encrustations ('sublimate') on fracture surfaces and in extensional cracks. Subsequent recrystallization resulted in complex exsolution intergrowths with antimony fractionation to the evolving crystal–vapor interface. Heavy metal fractionation between sulfosalt and vapor enriched the vapor phase in heavy metals that subsequently precipitated as complex Bi–Hg–Sn sulfosalts in discrete areas (paleo-fumaroles) close to the paleo-surface in a manner analogous to modern-day fumaroles on active volcanoes such as Vulcano, Italy. As in similar paleo-fumaroles (e.g., El Indio, Chile and Lepanto, Philippines), the most characteristic reaction sequence is the partial replacement of the early pyrite by enargite and Fe-tennantite. It is proposed that this reaction tracks the decrease in the pressure of the underlying magmatic-vapor reservoir because of the sustained discharge of vapor to the surface.


Based on the Sterne-Inkson model for the self-energy correction to the single-particle energy in the local-density approximation (LDA), we have implemented an approximate energy-dependent and [bold k]-dependent [ital GW] correction scheme to the orthogonalized linear combination of atomic orbital-based local-density calculation for insulators. In contrast to the approach of Jenkins, Srivastava, and Inkson, we evaluate the on-site exchange integrals using the LDA Bloch functions throughout the Brillouin zone. By using a [bold k]-weighted band gap [ital E][sub [ital g]] and a plasmon frequency [omega][sub [ital p]] determined by valence-electron density for the estimation of the dielectric constant, our approach retains the first-principles nature for the single-particle energy correction. Test calculations on semiconductors such as diamond, Si, Ge, GaAs, GaP, and ZnSe show good results with the [ital GW]-corrected gap values generally within 10% of the experimental values. It is shown that an accurate and well-converged LDA result is very important for the correct self-energy correction, and its convergence with respect to the number of [bold k] points needed in the computation is much slower than that in the LDA calculation.


A clear understanding of the issues surrounding climate change, global warming, air and water pollution, ozone depletion, deforestation, the loss of biodiversity and global poverty is essential for every manager in the hospitality industry. Present and future hospitality executives need to know how sustainable management systems can be integrated into their businesses while maintaining and hopefully improving the bottom line. Sustainability in the Hospitality Industry explores innovative ways to tackle the ever increasing costs of energy and water as well as the moral, ethical, social and political arguments for taking action. This book uses case studies throughout to explore the following key issues:*How can hospitality properties and equipment be designed to use less resources?*What are the benefits of using more sustainable food and beverage sources?*How can environmental impacts be reduced and profitability increased?*How can properties integrate sustainability management systems and stay one step ahead of the competition?*How can the reputation of a hospitality operation be improved to attract investment by incorporating responsible marketing and corporate social responsibility policies?


One titrimetric and two spectrophotometric methods which are simple, sensitive, and economic are described for the determination of sumatriptan succinate (STS) in bulk drug and in tablet dosage form using N-bromosuccinimide (NBS) as a brominating agent. In titrimetry, aqueous solution of STS is treated with a measured excess of NBS in acetic acid medium, and after the bromination of STS is judged to be complete, the unreacted NBS is determined iodometrically (method A). Spectrophotometric methods entail addition of a known excess of NBS in acid medium followed by the determination of residual NBS by its reaction with excess iodide, and the liberated iodine (I3 −) is either measured at 370 nm (method B) or liberated iodine is reacted with starch followed by the measurement of the blue colored starch-iodine complex at 570 nm (method C). Titrimetric method is applicable over range 1.0–10.0 mg STS (method A), and the reaction stoichiometry is found to be 1 : 3 (STS : NBS). The spectrophotometric methods obey Beer's law for concentration range 0.6–15.0 μg mL−1 (method B) and 0.2–4.0 μg mL−1 (method C). The calculated apparent molar absorptivity values were found to be 2.10 × 104 and 7.44 × 104 L mol−1 cm−1, for method B and method C, respectively.


This paper presents a new design concept to increase the efficiency and the power density of planar magnetics. In contrast to the existing magnetics, which are built using the balanced magnetic flux density design, the proposed design concept generates unbalanced magnetic flux density across the different parts of the magnetic core. The theoretical analysis shows that the core loss of the unbalanced-flux design can be reduced by more than 50% compared to the existing one. The core loss reduction brings several benefits to planar magnetics such as: high power capability, better thermal performance and wider safe operating area (SOA). The proposed design is experimentally evaluated and compared with the balanced-flux design. The experimental results are in good consistency with its theoretical counterparts. The measured core loss are decreased by more than 50% and the power density is increased by more than 250%.


To explore the effects of Nordihydroguairetic Acid (NDGA) and the role of the histone deacetylase HDAC‐6 in oxidative stress responses, we are performing RNA interference (RNAi) in the model organism C. elegans. NDGA is a polyphenolic lignan known for its antioxidant properties and is found in large quantities in the long‐lived desert plant Larrea tridentata. HDAC‐6 is an enzyme involved in the acetylation of α‐tubulin microtubules, Hsp90 and the redox regulatory protein peroxiredoxin (Prx). Preliminary results indicate that cultivation of worms on 1mM NDGA‐enhanced medium results in reduced body size with no apparent affect on fertility. An RNAi construct of 233bp targeting exon 8 of the HDAC‐6 gene on chromosome IV was created by amplifying genomic DNA (gDNA) from wild‐type C. elegans. The amplified product was cloned into the RNAi expression vector pL4440. The vector contains T7 RNA polymerase promoters flanking the multiple cloning site, enabling the production of double‐stranded RNA upon induction. Ongoing experiments will include cellular assays to elucidate a possible phenotype related to the role of HDAC‐6 in oxidative stress responses.


'evaluation'. Yet Vásquez has not identified these two planes, nor has she clarified whether and how the positions taken in the two chapters relate to each other. Nevertheless, this book has several strengths. First, it provides a congregational site for linguistics, media/digital studies and business communication studies with a series of exemplary analyses of online review texts with the linguistic and discursive approaches in a computer-mediated communication context. Vásquez effectively explores the wide range of possibilities of approaching the online discourses of customer reviews, demonstrating the feasibility of working with data from a multi-dimensional perspective. The themes discussed in Chapters 2–5 are inspiring for those scholars interested in discourse, especially novices. In addition, this book contributes to the promotion of an interdisciplinary collaboration between linguistics and market research and linguistics and other sociological inquiries. It raises several other sociologically driven issues, such as authenticity, democratization of expertise and pedagogical implications, all of which are provocative to readers. Thus, this work is a worthwhile addition as it is a valuable resource both for discourse scholars and for other scholars with an interdisciplinary background. Second, Chapters 2–5 provide the readers with a clear, well organized and succinct review of the theoretical resources, and the review of literature in each chapter becomes an ideal site providing easy access for researchers to trace the theoretical concepts. Vásquez teases out the main theoretical thread within each chapter with the relevant references available to a wide range of literature. This is quite helpful for guiding novice researchers to locate cutting-edge themes in discourse studies such as evaluation in discourse, discursive construction of identity, sociolinguistic approach to narrative and intertextuality. Finally, the corpus includes reviews from various categories of products, ranging from food recipes, hotels, and restaurants to entertainment. The discursive and pragmatic features of online reviews for different categories are demonstrated, which consequently offers pedagogical implications for digital literacy theorists and educators. The techniques and discursive resources employed by the reviewers to provide advice, complaints, assessments of products and so on can be applied for pedagogical purposes in professional settings or workplaces. Although, as noted earlier, it does not coherently connect the four themes, this book is still worth recommending to readers who are interested in digital discourse studies, for it applies discourse analytic methods to online reviews and thus provides the readers with a theoretical prism to look at the online reviews as one form of digital literacy.


Echocardiographic strain and strain rate imaging are new technologies used to evaluate myocardial function. Strain and strain rate derived from either tissue Doppler imaging (TDI) or two-dimensional (2D) speckle tracking has a high sensitivity for the early detection of myocardial dysfunction. Those new noninvasive diagnostic methods can distinguish active myocardial movement from passive exercise in order to quantify intraventricular dyssynchrony and to assess parts of myocardial function,so the spectrum of potential clinical applications is very wide including assessment of myocardial viability and early detection of patients with different etiologies of heart disease. In addition,strain and strain rate image also provid important prognostic information.This article explains the concepts behind of strain and strain rate for TDI-derived and speckle tracking 2D-strain derived deformation imaging,presents the clinical application of these new ultrasound methods,and notes the limitations of these technologies and development prospects,which recently have become a hot subject for cardiovascular ultrasound clinicians at home and abroad.


JSON Web Tokens (JWT) provide a scalable, distributed way of user access control for modern web-based systems. The main advantage of the scheme is that the tokens are valid by themselves – through the use of digital signing – also imply its greatest weakness. Once issued, there is no trivial way to revoke a JWT token. In our work, we present a novel approach for this revocation problem, overcoming some of the problems of currently used solutions. To compare our solution to the established solutions, we also introduce the mathematical framework of comparison, which we ultimately test using real-world measurements.


The article is devoted to the development of software of information and analytical support for regional security management. The authors formulate the concepts of configuration of a network-centric management support system and its dynamic configuration. The conceptual scheme of the configuration in the notation of ER diagrams and its implementation in the form of a configuration file is proposed. The technology for dynamic configuration of multi-level network-centric information and control systems is described. The technology is designed for automated deployment of a network of software agents and their parametric configuration depending on the context of the application problem being solved


Distributed System is a class of computing systems in the field of computing where the hardware or software components of the system are located at networked locations. Computers that are the part of this system can communicate and coordinate their action only by exchange of messages in the system. Mutual exclusion is a mechanism in which multi-process can make access to the single sharable resource without affecting the integrity of the resource. The number of messages among the sites of the distributed system is one of the very prime concerned issue in analysing the performance of any algorithm. Also the amount of data structures needed in the one of prime consideration in the performance analysis of algorithm. The algorithm proposed in this paper reduces the number of messages to a large extend and also there is need of a single queue as a data structure.


Benefitting from the unequaled precision of the pulsar timing technique, binary pulsars are important testbeds of gravity theories, providing some of the tightest bounds on alternative theories of gravity. One class of well-motivated alternative gravity theories, the scalar–tensor gravity, predict large deviations from general relativity for neutron stars through a nonperturbative phenomenon known as spontaneous scalarization. This effect, which cannot be tested in the Solar System, can now be tightly constrained using the latest results from the timing of a set of seven binary pulsars (PSRs J0348+0432, J1012+5307, J1738+0333, J1909−3744, J2222−0137, J0737−3039A, and J1913+1102), especially with the updated parameters of PSRs J2222−0137, J0737−3039A and J1913+1102. Using new timing results, we constrain the neutron star's effective scalar coupling, which describes how strongly neutron stars couple to the scalar field, to a level of αA≲6×10−3 in a Bayesian analysis. Our analysis is thorough, in the sense that our results apply to all neutron star masses and all reasonable equations of state of dense matters, in the full relevant parameter space. It excludes the possibility of spontaneous scalarization of neutron stars, at least within a class of scalar–tensor gravity theories.


Methylation of toluene with methanol to synthesize p-Xylene was performed in a fixed-bed reactor. HZSM-5 zeolite as a catalyst was prepared by modification with La2O3. In addition, effect of steam treatment for La2O3-modified HZSM-5 on its catalytic performance was investigated as well. The properties of as-prepared catalysts were characterized by XRD, BET and NH3-TPD. The results indicate that modification with La2O3 can narrow the size of HZSM-5 channel effectively. And more than 90% selectivity of p-Xylene is obtained over HZSM-5 with loading of 24% and 30% La2O3. However, above La2O3-modified HZSM-5 with high-selectivity exhibit a poor stability for time on-stream of the methylation reaction. Steam treatment of La2O3-modified HZSM-5 can improve its stability and shape selectivity, decreasing by-products. These effects can be attributed to distortion & narrowing of HZSM-5 channel and reduction of HZSM-5 strong Bronsted acid sites during steam treatment. As a result, the excellent catalytic performance is obtained over 24.0% La2O3-modified HZSM-5 by steam treatment at 773 K for 1.0 h, being 23% conversion of toluene, 93% selectivity of p-Xylene during time on-stream.


In assuring the order of market economy,the professional associations' self-discipline function is eventually noticed and then approved by all walks of life as a cure to the market malfunction and the governmental loss of control.In recent years,the related national policies give a boost to professional associations,but because of the old thinking habits,the imperfect legislation,their improper positioning and so on,they fail to fulfill their due function in the market economy.The Folk Commerce Chamber of Wenzhou City's success indicated that professional associations must improve their services for their members,actively participate in governmental regulation of market and improve their democratic governing mechanism if they want to extend their space and assure of their governing position.


The aim of the project is to control the adhesion between cells by using acoustic expansion wave. The achievement of the project will be benefit to the drug delivery in the blood brain barrier in human brain, in order to treat brain disease that drugs are difficult to be delivered into target region in brain. Researches on opening blood brain barrier by using ultrasound had been carried out and obtained successful results on proofing that the effect of ultrasound wave caused the opening . The highlight of the project is the use of expansion wave instead of ultrasound wave to control the adhesion of cells. This report explains the method and preliminary results of the project that have been done during the six weeks research programme.


A straightforward method for the synthesis of virtually enantiomerically pure ruthenium(II) polypyridyl complexes [Ru(pp)(pp')(pp")](PF(6))(2), pp = bidentate polypyridyl has been developed. The synthesis draws from the readily available racemic starting material cis-[Ru(pp)(pp')Cl(2)] and the natural amino acids l- or d-proline and relies on a dynamic asymmetric transformation under thermodynamic control.

This paper discusses learners' responses to metalinguistic feedback and their strategies in error correction in a Web-based Intelligent Language Tutoring System (ILTS) for German. The system consists of a grammar and a parser which analyses student input and provides error-specific feedback to grammar and vocabulary exercises. Furthermore, the ILTS employs a Student Model that matches feedback messages to learner expertise and provides remedial exercises. Two beginner German classes, 33 students in all, used the ILTS for grammar practice, submitting a total of 4405 sentences for analysis. The results indicate that for the vast majority of sentences (79.5%) students read and attended to system feedback. Moreover, as iterations increased students paid more attention to the feedback messages.


There are approximately 3.300 universities in Indonesia, which consists of 3.200 private universities and 100 public universities. The growth of private universities was 8 percent annually, or an average of 200 universities per year. The rapid development of private universities results in increasingly competitive competition in acquiring new students. In higher education industries, winning the competition means that the high school graduates choose selected universities to continue their studies. Brand equity is one of the important concept in brand management because strong brand equity will make their brand chosen by its prospective customers. In contrast to general companies which use marketing mix variables as a source of brand equity, universities have a wide variety of targets. So the role of personal communication is very important to validate a university brand. Other forms of personal communications are words of mouth communications (WOM) and communication through the internet media (viral marketing). This research aims to understand the effects of WOM, viral marketing, and brand equity of private universities on decision to choose private universities. Data in the forms of brand equity variables, WOM variables, viral marketing variables, and decision to choose variables are obtained from the questionnaires. The number of samples taken is as many as 750 from high school students in Jakarta and Tangerang. The selected private universities are Mercu Buana University, Trisakti, Bina Nusantara, Gunadarma, Budi Luhur, and Esa Unggul. The data are statistically processed by the method of structural equation modeling (SEM) using SPSS and AMOS. The results of this research indicate that the decision to choose is influenced by brand equity and WOM, while the brand equity is significantly influenced by WOM communications and viral marketing. Viral marketing do not significantly influence the decision to choose, it influence to decision to choose through brand equity. So, private universities should be able to build strong brand equity through positive WOM and viral marketing. The success of managing both WOM and viral marketing can be used as an advantage to win the competition among private universities. DOI: 10.5901/mjss.2015.v6n5s5p118


An algorithm, THERMODER4, based on Jacobians, is presented for automating the symbolic derivation of expressions for thermodynamic derivatives for chemical systems, to complement algorithms given previously for unrestricted simple and complex systems.

The aim of this study was to investigate the relationship between number sense and the different components of working memory in Dutch children in preschool. A sample of 154 children aged five to seven was required to perform tasks designed to assess their number sense and the capacity of their working memory and its different components. The results suggest a significant correlation between the different constructs, implying a positive relationship between number sense and the different components of working memory. Furthermore, working memory appears to predict 37% of the variance in number sense in this sample of young Dutch children.


The aim of this study is to carry out the structural relations of parameters of school-based management based on decentralization, responsibility, participation, organizational culture, and organizational commitment. This study is an applied and survey. The statistical population of this research is all of the managers and teachers of Tehran city, of which 148 people (119 teachers and 29 managers) have been selected based on random sampling. The data have been collected using a questionnaire, whose admissibility and constancy have been proved in accordance to the view of related experts. In order to analyze data, Lisrel software has been used. Findings of study show that among the studied indexes, the organizational commitment with a path coefficient of 0.89; responsibility with a path coefficient of 0.86; participation with a path coefficient of 0.78; decentralization with a path coefficient of 0.73; and organizational culture with a path coefficient of 0.69, respectively maintain the most impact on the implementation of school-based management system in the schools of Tehran city. The principle of school management (school-based management) coupled with participative management is one of the approaches adopted by the majority of pioneering countries in a bid to enhance the efficiency of school management and to improve the quality of academic progress of pupils, which should be taken into consideration by the planners and decision-makers of our country's educational system. The theoretical and applied allusions of the findings were discussed.


----------------------------------------------------------------------------------------------------------------------------------ABSTRACT: This review paper discusses about Omicron and the covid -19 vaccines action against the Omicron. The seriousness of this variant is very less initially as everyone thought that our covid vaccines are immune enough against this strain. Slowly we realized how this variant is going to show its impact on our lives and immediately forcing us to check the capability of the vaccines available now and leaving us to question the necessity of inventing new vaccines for Omicron if needed. The main goal of this article is to create an awareness to public about the omicron, to discuss how effectively the treatments and vaccines of covid work for Omicron.


We report on study of photonic device based on a new spectral Raman converter allowing conversion from incoherent double-scale pumping laser pulses into coherent solitons. The developed photonic device features saturable absorption in the fibre cavity of synchronously pumped Raman laser. Conditions are identified allowing conversion efficiency over 45%. The limitations and advantages of the proposed approach are demonstrated, and also the prospects of its implementation in an all-fibre configuration. Efficient conversion of noise-like laser pulses into coherent solitons through nonlinear Raman shift phenomena enables attractive prospects of application of localised noise-like wave objects capable of carrying relatively high energies.


CagA is a multifunctional toxin of Helicobacter pylori that is secreted into host epithelial cells by a type IV secretion system. Following host cell translocation, CagA interferes with various host–cell signalling pathways. Most notably this toxin is involved in the disruption of apical–basolateral cell polarity and cell adhesion, as well as in the induction of cell proliferation, migration and cell morphological changes. These are processes that also play an important role in epithelial‐to‐mesenchymal transition and cancer cell invasion. In fact, CagA is considered as the only known bacterial oncoprotein. The cellular effects are triggered by a variety of CagA activities including the inhibition of serine–threonine kinase Par1b/MARK2 and the activation of tyrosine phosphatase SHP‐2. Additionally, CagA was described to affect the activity of Src family kinases and C‐terminal Src kinase (Csk) suggesting that interference with multiple cellular kinase‐ and phosphatase‐associated signalling pathways is a major function of CagA. Here, we describe the effect of CagA on protein kinase C‐related kinase 2 (PRK2), which acts downstream of Rho GTPases and is known to affect cytoskeletal rearrangements and cell polarity. CagA interacts with PRK2 and inhibits its kinase activity. Because PRK2 has been linked to cytoskeletal rearrangements and establishment of cell polarity, we suggest that CagA may hijack PRK2 to further manipulate cancer‐related signalling pathways.


Due to the wide use of web resources such as online banking, social networking, education, entertainment, downloading software, and a rise in the economy's digitalisation, the prevalence of online fraud is rising. Phishing is mostly a launch attack on the internet. Phishing is a criminal attack that obtains credential data such as bank information, username, password and credit card information, etc which can be used to damage a single victim or the entire organisation. Criminals always use disasters as an opportunity to take advantage of recessions, hurricanes, and difficult times. The latest example is the Covid-19 pandemic. The phishing attacks are growing rapidly in 2020, cyber attackers launched Covid-19 themed phishing attacks against healthcare facilities, the unemployed and workers. A lot of anti-phishing solutions are available heuristic detection, virtual similarity detection, black and whitelisting, and machine learning. This paper compares various research for each machine learning technique in terms of detecting phishing attacks and discusses the benefits and drawbacks of each methodology. In addition, this paper presents a detailed list of existing phishing attack threats as well as potential research directions in this sphere.


The results of total ionizing dose (TID) experiments on fully depleted silicon-on-insulator (FDSOI) static random access memory (SRAM) are presented. Using 60Co gamma irradiation, tests were conducted at multiple voltages and with and without read and write assists. The results demonstrate cell stability past 200 krad(Si) TID in standard operational modes. The impact of read and write assists and read timing via margin mode tests are examined. We also report input–output (IO)-level translation circuit failures, as well as anomalous circuit failures attributable to IO at relatively low TID dose. Finally, we show post-TID anneal and low-voltage SRAM results.


Two chalcogenide films with composition Ge25-Sb10+xS65 (x = 0, 10) and Te20As30Se50, called 2S1G and TAS, respectively, are studied. These materials have high linear and nonlinear refractive indices and present interesting photosensitive behavior toward bandgap light. Further, these chalcogenides glasses can be deposited in an amorphous thin ?lm for optical coatings or waveguides. Their properties and limitations, including their photoinduction effects, nonlinear Kerr effect, photodiffusion of silver, and aging, are discussed. © 2010 Chinese Optics Letters.


Fully considering the government's economic and social development and related energy planning, based on energy consumption per GDP and other binding indicators, the change of electrical energy in terminal energy consumption has been analyzed and the forecasting model of electricity consumption in the whole society has been built. The electricity consumption in the whole society of Henan in 2020 has been successfully forecasted through a specific example. The feasibility and practicability of this forecasting method are verified. This method can provide the basis for power planning and business decision-making.


Pregnancy loss is a common and devastating pregnancy complication. Recurrent early miscarriage (REM) is defined as two or more consecutive pregnancy losses during the first trimester of pregnancy. It is a distinct entity and in approximately 50% of these patients, the underlying cause is never established. REM can be idiopathic, i.e. of unknown cause, be related to infections, anatomical or chromosomal abnormalities and can also be related to the presence of autoimmune connective tissue diseases or antiphospholipid antibodies (aPL). Hydroxychloroquine (HCQ) is an antimalarial immunomodulator and is currently being investigated for its role in the prevention of idiopathic REM and REM related to antiphospholipid antibodies (aPL). In this article we review the evidence that exists to date regarding the use of HCQ in the setting of unexplained REM and REM in relation to connective tissue diseases and aPL and antiphospholipid syndrome (APS).


Touching (T) an arbitrary position 4 on a screen 1 displayed on a touch panel sets a plurality of screen areas A, B, C, and D into which the screen is divided using lines L1 and L2 which contain the position 4 and which traverse the touch panel screen 1, and a first quadrant, a second quadrant, a third quadrant, and a fourth quadrant which correspond to the screen areas are set. Touching (T) an arbitrary position 5 belonging to one C of the screen areas allows a character assigned to the corresponding quadrant (third quadrant) to be recognized. Releasing the character at the position 5 allows the character assigned to that quadrant to be confirmed.

This paper presents a reasonable approach to this issue, i.e., computer controlled magnetorheological finishing (MRF). In MRF, magnetically stiffened magnetorheological (MR) abrasive fluid flows through a preset converging gap that is formed by a workpiece surface and a moving rigid wall, to create precise material removal and polishing. Tsinghua University recently completed a project with MRF technology, in which a 66 mm diameter, f/5 parabolic mirror was polished to the shape accuracy of λ/17 RMS (λ=632.8nm) and the surface roughness of 1.22 nm Ra. This was done on a home made novel aspheric computer controlled manufacturing system. It is a three-axis, self-rotating wheel machine, the polishing tool is driven with one motor through a belt.

This study addresses analytical spatial resolution of samples in the 50-100nm thickness range when examined using a high convergence (semi-angle ~30mrad) beam such as would be associated with a C s corrected STEM. Achieving the highest spatial resolution microanalysis requires extremely thin samples, typically foils less than 200Å are called for. There have been numerous studies describing the elastic and inelastic scattering mechanisms that broaden the probe profile as it traverses the TEM sample. In the microelectronics industry, many samples are prepared using the FIB and are often somewhat thicker than 500Å, especially if they are from isolated and electrically tested devices. Despite being too thick there is still significant interest to characterize such samples and an estimate of the expected resolution is called for. of sample


One of the central problems of the theory of alternative algebras is that of the construction of a basis, posed by Shirshov at the end of the 1950's. It follows from known results of Dorofeev, Shestakov, and Filippov that the identities, and hence the construction itself of a free alternative algebra, depend essentially on the number of its generators. By an algebra we mean an alternative algebra over an integral domain Φ, containing the element 1/6; Alt[A] is the free algebra on the set of free generators X; as usual, X = {xlt x s , . . ., z,n> · · ·}> Xn = {xlf xt, . . ., x n } . We introduce the following notations in the algebra Alt [a, ft, c]: Κ = (α, b, e), Rx is the operator of right multiplication, x.y — Rxy — Rxyι α "° •Rb.e» Ρ = c.o> Υ = Ra.b, ω = αγβ βγα. The composition of a finite number of operators α, β, -γ, ω is called a compound associativity operator. The compound associativity operator


In spite of meticulous planning, well documentation and proper process control during software development, occurrences of certain defects are inevitable. These software defects may lead to degradation of the quality which might be the underlying cause of failure. In today"s cutting edge competition it"s necessary to make conscious efforts to control and minimize defects in software engineering. However, these efforts cost money, time and resources. This paper identifies causative factors which in turn suggest the remedies to improve software quality and productivity. The paper also showcases on how the various defect prediction models are implemented resulting in reduced magnitude of defects.


This article studies Paul Valéry's personal reflection on photography, as it appears in his essay "Le Discours du Centenaire de la Photographie," based on a speech given at the Sorbonne in 1939 to members of the French Academy. It stresses the relationship between this essay and the French poet's writings on painting and aesthetics, in particular his work on Corot. Moreover, it analyzes the synthetic character of Valéry's critical approach, which attempts to bring together the language of poetry, philosophy and science when dealing with this utterly modern visual language. Photography is celebrated here as a unique art form that can at the same time imitate and reproduce nature perfectly, while allowing mankind to create a cosmological vision of life and the universe. In other words, the poet underlines in this text the utmost modernity of photography, at a time when many in France were still reluctant to acknowledge its artistic identity.

Author(s): White, Terra Evelyn | Advisor(s): Guzowski, John F. | Abstract: It is increasingly recognized that the immune system can exert profound effects on the central nervous system. Past research has shown that peripheral immune activation has the capability of affecting cognition, including memory function. While there has been much research on how immune stimulation can affect neuronal function or behavioral performance in memory tasks, there is a lack of research linking molecular alterations to behavioral impairment. This dissertation examines effects of acute immune challenge on hippocampus-dependent memory with a systematic approach that links molecular mechanisms, neural circuit activity, and behavior within a consistent experimental model. For all experiments, subjects received a systemic injection of lipopolysaccharide (LPS) that served as a mild immune challenge that reliably induced a proinflammatory tone within the brain. Afterward, subjects were tested for context discrimination memory followed by analysis of circuit activity patterns and/or neural gene expression in dorsal hippocampus. Chapter 2 asks whether pharmacological attenuation of neuroimmune activation prevents impairments of contextual memory and circuit activity that had been previously observed during acute neuroinflammation. Blocking neuroimmune activation successfully prevented LPS-induced impairments in memory and circuit activity, and the extent of circuit activity disruption was associated with behavior of a given subject. In Chapter 3, gene expression was analyzed for the same subjects employed in Chapter 2. Using statistical modeling, differential gene expression was linked to circuit activity patterns and memory performance in order to build an overarching experimental model of neuroimmune modulation of memory function. Furthermore, specific genes with potential roles in neuroimmune-mediated impairment were identified. The study detailed in Chapter 4 asked whether environmental enrichment, a behavioral intervention providing enhanced physical, cognitive, and social stimulation, is able to protect memory impairment during neuroinflammation. Unlike the pharmacological intervention used in Chapter 2, this study did not find robust protective effects associated with environmental enrichment, but ways in which the experiment could be improved are discussed. Collectively, the experiments contained within Chapters 2-4 contribute knowledge on fundamental interactions between an activated immune system and memory processes. Future study is needed for translation of findings into therapeutic advances for people suffering from cognitive symptoms during proinflammatory disease.


A special type of spatial dependence model has been developed for the valuation of residential property by using a Bayesian approach which takes into account the unique attributes of Hong Kong property. Inspired by an approach that bases transactions on nearest neighbor estimation, the current model has fine-tuned the spatial dependence method of deriving value from the transactions of the real estate closest in proximity by factoring in differences in structural and auxiliary attributes for more precise property valuation. The model is established on a dataset that covers all residential real estate transactions in a new town in Hong Kong during a given period of time. This model excels other valuation methods with its unique reference to attribute differences, which may impact the valuation results of properties in close vicinity. With this calibration method, we hope to improve the accuracy of real estate appraisals, thus enabling potential homeowners, lenders and investors to make better informed decisions.

Information about the three‐dimensional structures of complex biological molecules is an indispensable research tool for many fields of study, including biology, chemistry, pharmacology, and computer science. The Protein Data Bank (PDB) is an public digital archive providing access to structures of nucleic acids, proteins, and large macromolecular machines determined experimentally by X‐ray crystallography, nuclear magnetic resonance (NMR) spectroscopy, and 3‐dimensional electron microscopy (3DEM). PDB structures undergo validation for structural plausibility upon their deposition into the PDB using the program Mogul, which cross references each deposited structure against similar data in the Cambridge Structural Database (CSD). Ligands associated with PDB structures are a common source of structural inaccuracy. In this study, a programmatic pipeline was developed to determine if ligand geometric accuracy could be improved using known computational tools. Ligands with dubious geometry were identified through a Python mining code. A sample set of the identified structures was remodeled into minimum energy conformations using the molecular dynamics program AMBER and then fit to the original experimental density maps using the molecular modeling program Coot. The refined models were compared to the original models in the PDB as well as to similar structures in the CSD using the deposition statistical validation server. Preliminary results suggest that the pipeline effectively identifies and improves ligand structures that possess inaccurate geometry. This method can be used to evaluate and improve the accuracy of specific ligands in structures both archived and pending deposition.

The recombination mechanisms in a Zn(Cd)S:Ag phosphor powder have been probed by luminescence and flash‐photolysis time‐resolved dielectric loss techniques. The influence of Pd‐microislands chemically deposited thereon, alone, and in conjunction with recombination mediators phenylhydrazine and phenylacetic acid (in xylene solution) on the recombination pathways was studied. The Pd deposit affects recombination by increasing the fraction of the particle volume dominated by the surface processes, by providing a pathway for photoelectrons to reach the (negative) surface to participate in surface recombination, and by providing recombination centers per se. The implications of these results for heterogeneous photocatalysis are discussed.


The effects of low temperature and poor light was studied on physiological and biochemical characteristic in cucumber seedlings. The results showed that soluble sugar contents and soluble protein contents under low temperature and poor light increased,and soluble sugar contents of Guonong 25 was higher than that of Guonong 41. Peroxidase (POD) activities,ascorbate peroxidase (APX) activities,dehydroascorbate reductase (DHAR) activities and lipoxygenose (LOX) activities also increased,but protective enzyme activities increased more rapidly in Guonong 25 than that in Guonong 41. The results also showed that contents of malondialdehyde (MDA) of Guonong 25 was different from that of Guonong 41,MDA contents of Guonong 25 was lower than that of CK,but MDA contents of Guonong 41 was higher than that of CK from 3-9 d.


In this article, we illustrate the effect of imposing symmetry as prior knowledge into the modelling stage, within the context of chaotic time series predictions. It is illustrated that using Least-Squares Support Vector Machines with symmetry constraints improves the simulation performance, for the cases of time series generated from the Lorenz attractor, and multi-scroll attractors. Not only accurate forecasts are obtained, but also the forecast horizon for which these predictions are obtained is expanded.


The Angular Resolution Limit (ARL) on resolving two closely spaced polarized sources using vector-sensor arrays is considered in this paper. The proposed method is based on the information theory. In particular, the Stein's lemma provides, asymptotically, a link between the probability of false alarm and the relative entropy between two hypothesis of a given statistical binary test. We show that the relative entropy can be approximated by a quadratic function in the ARL. This property allows us to derive and analyze a closed-form expression of the ARL. To illustrate the interest of our approach, the ARL, in the sense of the detection theory, is also derived. Finally, we show that the ARL is only sensitive to the norm of the polarization state vector and not to the particular values of the polarization parameters.


ABSTRACT The Society for Advancement of Sexual Health (SASH) formed a committee to developing a working definition of sexual health for review by the executive board. The process of developing a definition, not based primarily on the absence of dysfunction or disease, encouraged review of some definitions, descriptions, and visions of the World Health Organization (WHO) and several professional associations. The result of the committee's efforts was a working definition for ongoing review and commentary.


Non-genetic effects, heritability and genetic, phenotypic and environmental correlations between the weights at birth (BW) 8 months (WW) and 12 months old (YW), daily weight gain from birth to 8 months (DGW) and from birth to 12 months old (DGY) in a Guzera herd were estimated. Data collected from 1979 till 1984 were obtained from the Teaching and Research Farm, Ilha Solteira, UNESP, and referred to 842 calves, progenies of 22 sires, each one with a minimum of 3 offspring. The statistical analysis was done by the least-squares method, using mixed model that included the randon effect of sire and the fixed effects of sex, birth season, birth year of calves, age of dam (class) and interactions between fixed effects. The sex effect was statistically significant on all weights and weight gains studied, while the birth season and birth year did not influence signiflcantily only BW. The age of dam influenced significantily BW, YW and DGY. The milking cow effect on weight, except for BW, and weight gain was also studied and was not statistically significant. Heritability estimates, by paternal half-sib correlation, were: 0.24 ± 0.10; 0.14 ± 0.08; 0.11 ± 0,07; 0.08 ± 0.07 and 0.06 ± 0.06, respectively for BW, WW, DGW, YW and DGY. The estimates of genetic correlation were high and, in general, somewhat lower when involved BW.


Abstract : This report describes the development of a mathematical model (blanking model) for a human operator's tracking performance under visual interruptions via blanking the target in a simulated manned antiaircraft artillery system. The basic ideas of the Luenberger observer theory are extended to develop an observer model with time-varying gains. The model consists of a reduced-order observer, a feedback controller, and two noise components. The blanking model is then obtained from the general model under an exponential-gain assumption. Four blanking time constants associated with the exponential gains are introduced to relate to the human operator's short-term memory. The parameters of the model are identified from a curve-fitting computer program. Model predictions of both azimuth and elevation tracking errors for several flyby and maneuvering trajectories are shown to be in excellent agreement with the empirical data obtained from the blanking experiments. It is concluded that the blanking model developed in this report is a predictive model for a gunner's tracking performance with interrupted observations.


The aim of this paper is to establish the categories of adult persons which could be considered as the subjects incapable of giving consent for the participation in clinical trials – which is the expression used by the legislator that the author considers to be vague. In the first part of the paper, the author analyzes the issue whether the adult persons with restricted or terminated legal capacity belong to this category. The second and the third part of the paper represent a response to the question whether an adult subject with full legal capacity can be classified in this category for a particular reason. In the conclusion, the author states that the category of adult persons which could be considered incapable of giving consent for the participation in clinical trials includes only the individuals without full legal capacity and explains why such categorization is not adequate, suggesting the corrective solutions.

Battered Husbands (TAKUSA or Takot Sa Asawa) are unusual societal issues. An abused husband suffers the same emotional, verbal and physical abuse as a battered wife, but is less likely to report these crimes to authorities. The study was conducted to divulge the actual scenario on the tempestuous experiences, psycho-social behavior, and coping mechanisms of the battered husband (TAKUSA). Qualitative type of research through case study approach was used. Ten (10) selected respondents who met the criteria set by the researcher from among 120 recommended samples using purposive sampling. The Third Congressional District of Nueva Ecija, Philippines composed of Cabanatuan City, Palayan City, Bongabon, Laur, Gen. Natividad, Gabaldon and Santa Rosa was the study locale. Prior consent was established before the conduct of the study. Interviews, observations, and checklist were the main instruments. Results revealed that the respondents have varied lifestyles, tempestuous experiences, reactions, and coping mechanisms. It deduced that the battered husband has low self-esteem and social acceptability; manifestations of stress, anxiety and depression. Such feelings are recommended for psychological interventions, conduct family counseling and development of intervention activities, identify and establish a supportive network of relationships where they can voice out their problems.

Due to the need to quantify carbamates from the CO2 gas chemical absorption process by monoethanolamine (MEA) and diethanolamine (DEA), analytical curves by IR spectroscopy were obtained with the aim of quantifying MEA and DEA carbamates and MEA, DEA and methyldiethanolamine (MDEA) in pure solutions and mixtures. The analytical procedure considered the preparation of standard samples constituents of the calibration curves and their quantification using reference instrumental techniques – potentiometric titration, gravimetry and GC-FID. The standard samples of pure amines were quantified by potentiometric titration, getting the accurate detection of the equivalence point. The compositions of the analytical standards of the mixtures were established according to a triangular diagram for mixtures and the content of each component was determined by gravimetry and GC-FID. The carbamate hidrolysis and its thermal degradation were factors that limited the use of potentiometric titration, HPLCMS/MS and GC-FID as reference techniques in their quantitation. These restrictions, added to the fact of not having commercial availability of these carbamates, led the use of H NMR spectroscopy for the quantitative determination. The calibration curves resulted in an excellent adjustment of the expected values related to the reference values and maximum error of prediction of 0.594 %. Two chemical absorption processes of CO2 gas were performed in semi-pilot scale and the obtained results were of 1.02 % and 0.98 % of absorbed CO2 by MEA and DEA solutions, respectively. Both processes were simulated using Aspen Plus software, presenting 1.18 % of CO2 absorbed by MEA solution and 1.00 % by DEA solution. Key-words: infrared; alkanolamines; calibration curves; CO2.


Purpose. The aim of the study was to analyse the most promising ways to use natural light in new modern construction projects and in the reconstruction of existing buildings and modern methods of designing artificial lighting and interior design using new sources, taking into account the psychophysiological condition of the human body. Methods. In order to achieve the set objectives, the current standards of lighting environment, design solutions for natural light in workplaces, were analysed and the ecological and climatic conditions of lighting on the example of Dnipro were taken into account. Existing artificial lighting systems were analysed, the impact of lighting levels was considered, as well as sources on the state of human health, ability to work and safety. Topicality. The article considers the problem of improving the safety and comfort of the lighting environment under optimal working conditions, which preserve the health of workers and create the prerequisites for maintaining a high level of efficiency. The scientific novelty lies in a comprehensive approach to evaluating the hygienic characteristics of light and colour environment, as well as the application of results for the calculation of lighting systems and recommendations for the design and interior decoration of premises for work of high visual complexity. Practical significance. The research results could be provided to ensure safety of workers in the premises, with categories of work of high, very high and highest precision. The importance of the work lies in the need to take into account the complex effect of a light-coloured environment on the state of workers. The research results proved that safe and comfortable lighting should be designed on the basis of a multifactor model that takes into account the exposure of light of different origins at a workplace with obligatory consideration of the impact on human health during work, as well as determining the energy efficiency of workplace lighting

A chaos particle swarm optimization (CPSO) algorithm based on the chaos operator (CS) is proposed for global optimization problems and parameter inversion of the nonlinear sun shadow model in our study. The CPSO algorithm combines the local search ability of CS and the global search ability of PSO algorithm. The CPSO algorithm can not only solve the global optimization problems effectively, but also address the parameter inversion problems of the date of sun shadow model location successfully. The results of numerical experiment and simulation experiment show that the CPSO algorithm has higher accuracy and faster convergence than the-state-of-the-art techniques. It can effectively improve the computing accuracy and computing efficiency of the global optimization problems, and also provide a novel method to solve the problems of integer parameter inversion in real life.

Weak atmospheric turbulence causes pulse broadening of an optical signal. In this article, we drive the pulse broadening as a function of turbulence strength by temporal moments directly. We derive pulse broadening dependency on turbulence strength and propagation distance when an optical signal propagates through atmosphere. This pulse broadening induces intersymbol interference (ISI) between adjacent pulses. Based on this derived results, we develop some observation patterns using a practical example.


The vomeronasal system (VNS) is an accessory olfactory system present in most tetrapods. Clas sically, the VNS has been associated with terrestriality in vertebrates; however, evidence emerged in recent years suggest that this sensory system appears earlier in tetrapods evolution and may play a role in chemosensory detection in aquatic environments. This sensory system has been described in anuran larvae. But, is the VNS functional in tadpoles? There are no experiments that evaluate the involvement of the VNS in chemodetection in tadpoles. However, a growing body of evidence suggests that the VNS could be a functional sensory system in anuran larvae: 1) The vomeronasal organ (VNO) appears during embryonic development and it is present throughout the larval phase. 2) The VNO contains bipolar neurons whose axons project to the accessory olfactory bulb (AOB) where they establish synaptic contact with telencephalic neurons. 3) The vomeronasal neurons express specific membrane receptors described in the VNO of tetrapods, and the G protein involved in intracellular signaling. 4) Electron microscopy analysis demonstrates that the vomeronasal neurons have apical microvilli as described in other groups and their ultrastructural features do not change during metamorphosis. Moreover, there are no differences in the ultrastructure of the synaptic connections in the AOB between tadpoles and adults. Tadpoles exhibit a large number of chemodetection mediated behaviors.


The technological revolution of the past 40 years may be measured by our increased level of understanding of physical mechanisms in a variety of fields. Physics has moved from protons and electrons to quarks and musons. Electronics has moved from resistors, capacitors, and vacuum tubes to silicon and copperbased microprocessors, and materials science has moved from synthetic rubber to buckyballs. Chemistry has moved from distillation to chiral synthesis, and biochemistry from penicillin to recombinant proteins. Similar advances have occurred for the tools available in the field of medicine. Diagnostic imaging has progressed from x-rays to magnetic resonance imaging. Surgery has progressed from scalpels to lasers, and cancer treatment from excising tumor masses to targeted chemotherapy. Treatment of heart attacks and strokes has evolved from bed rest to administration of clot-busting tissue plasminogen activator and streptokinase. Diagnostics has moved from thermometers to home pregnancy kits, with mapping the human genome a near-term reality. Blood purification is on the verge of a similar revolution. When the concept of bloodborne pathogens first arose, treatment consisted of bloodletting, a very crude form of blood purification. In the immortal words of the noted Philadelphia physician, Benjamin Rush, MD (1745–1813), 'if the patient dies you have not bled him enough.' Clearly the nonspecific removal of whole blood is not the ideal form of treatment for disease. As knowledge of the molecular basis of illness and disease increases, so too does the opportunity for more effective treatment by increasingly specific forms of blood purification. Routine blood purification procedures today – dialysis, hemofiltration, and plasmaphersis – are all nonspecific in nature, i.e., 'bloodletting'. As a result, such procedures discard not only undesired species such as uremic toxins or immune complexes, but also certain necessary substances such as plasma proteins. Indeed, a trade-off between adequate removal of 'bad' molecules and excessive removal of 'good' molecules often prevents complete purification of the blood. The ideal blood purification procedure would achieve specific removal of one or more targeted species. To achieve such precision, modern-day blood purification turns to the exquisite innate specificity of biologic molecules such as antibodies and enzymes.


The results of the optical monitoring between November 1994 and November 1995 of twenty γ -ray loud blazars included in the Torino blazar monitoring program are presented. All data were taken with the REOSC astrometric telescope of the Torino Astronomical Observatory, equipped with a pixels charge-coupled device (CCD) camera. Observations have been carried out in the standard B , V (Johnson), and R (Cousins) bands. Source magnitudes are calculated with respect to reference stars in the same frame. For half blazar fields it was possible to perform a photometric calibration through the observation of Landolt's fields during photometric nights. In the other cases either photometric sequences from the literature were adopted or, when lacking, magnitudes were simply normalized to their minimum value. Most of the monitored objects show a more or less pronounced brightness variability on both short and long time scales. In a few cases also noticeable intranight variations were detected. Data simultaneous to pointings of the Compton Gamma Ray Observatory (CGRO) are present in our light curves: when the γ data are available they will provide a useful information in order to understand the possible correlations between the optical and γ -ray emissions. For one source (PKS 2254+074) we performed also photopolarimetry, deducing magnitudes, amount of polarization, and position angle in the UBVRI bands.


A series of compounds similar to Pracinostat that contained benzimidazole ring and N‐hydroxyacrylamide attached at 5‐ or 6‐position were designed, synthesized, and evaluated as HDAC inhibitors. It was interesting to find that the corresponding derivative 1 with N‐hydroxyacrylamide attached at 5‐position was a potent HDAC inhibitor while the others at 6‐position were not. This is the first time to demonstrate the position difference plays important role in the HDAC inhibitory activities of the cinnamic hydroxamates.


Abstract : Subcultures with vaccine properties from virulent strains of the plague microbe may be selected according to the following features: On the Jackson-Burrows medium they should grow in the form of pigmentless colonies, on magnesium-oxalate agar of Higuchi--Smith they should form colonies of the III order and should not disclose a tendency for a loss of 'residual' virulence; they should be nonvirulent for mice in doses of 1x10 to the 7th power bacteria, and under the influence of ferrous salts their virulence should be raised but without the restoration of the capability for pigment formation and without the restoration of virulence; in a dose of 5000 bacteria they should cause immunity in 80--90% of white mice and guinea pigs in respect to virulent plague bacteria in a dose of 200 Dc1. A final judgement of the selected subcultures is decided following their approval on laboratory animals based on those tests which at the present time are accepted for evaluating vaccine strains of the plague microbe.


In this paper, we present research trends about machine learning-based medium access control technology for 6G requirements. The complex network environment of 6G requires more intelligent communication than the 5G environment. Particularly in the medium access control layer, plenty of studies are being conducted on resource allocation and random-access problems that have become difficult to solve with existing approaches due to the increased complexity of the network. This paper briefly introduces about 6G requirements and machine learning, then investigates the latest studies on resource allocation and random-access, which consider 6G requirements using machine learning techniques. Moreover, future research directions for machine learning-based medium access control technologies are also presented.


Penalty methods are often used to handle constraints in optimization problems. However, to find the optimal or near optimal set of penalty parameters is a hard task. Also, such values are problem dependent. This paper introduces the stochastic ranking approach to balance objective and penalty functions stochastically in a rank-based ACO metaheuristic. The results presented show that the simple inclusion of the procedure leads to an improved search performance, with respect to the standard penalty technique, when applied to discrete structural optimization problems


Introduction. VARK is very important to facilitate the development of nursing and midwifery students, helping translate theory into practice, and making what is learned in the classroom a reality. It is important to assess the learning style of students to cater for differing learning needs. The aim of the study were: 1) to identify learning style nursing and midwifery students, and 2) the differences of learning style between nursing and midwifery students. Method. A descriptive crosssectional study was performed by using VARK questionnaire version 7.8. A total of 241 students including 125 nursing and 116 midwifery students were participated in this study that selected using stratifi ed random sampling techniques. Data analysis used Chi square test and One Way ANOVA (α=0.05). Result. The study showed that 61.7% and 67.8% nursing and midwifery students in the fi rst year; 70.8% and 63.3% in the second-year were used multimodal learning preferences, respectively. There was no signifi cantly differences learning preferences between the fi rst and the second-year as well as between nursing and midwifery students (p>0.05). Discussion. The nursing and midwifery students have varies on the learning preferences however the majority of the students used multimodal. Therefore, an active learning method was recommended. Keywords: Learning style, Nursing and midwifery students, VARK


The origin of the irregular satellites of the giant planets has been long debated since their discovery. Their dynamical features argue against an in situ formation suggesting that they are captured bodies, yet there is no global consensus on the physical process at the basis of their capture. In this paper, we explore the collisional capture scenario, where the actual satellites originated from impacts occurred within Saturn's influence sphere. By modelling the inverse capture problem, we estimated the families of orbits of the possible parent bodies and the specific impulse needed for their capture. The orbits of these putative parent bodies are compared to those of the minor bodies of the outer Solar system to outline their possible region of formation. Finally, we tested the collisional capture hypothesis on Phoebe by taking advantage of the data supplied by Cassini on its major crater, Jason. Our results presented a realistic range of solutions matching the observational and dynamical data.


The article reveals rental mechanisms in economics, which, as the author forecasts, will increase its influence on all spheres of future society. It's shown that the substitution of profit by rent contradicts the historical trend of transition from the law of value to the law of surplus value as the regulator of economic relations.


StegoloPhodon has a pecular position in the taxonomy as well as in the phylogeny of order Proboscidea. In this article, some fossil teeth of StegoloPhoden pseudolatidens (YABE) hitherto considered to be the earliest form of StegoloPhodon were examined. The materials, DPI and M!, were obtained from the upper part of the Asakawa Formation (!ower Middle Mioccne) at Kitashioko, Omiya-machi, Naka-gun, Ibaraki Prefecture, North-eastJapan. The DP.4 is first known in this species. Compared with other specimens of StegoloPhodon (pseudolatidens, tsudai and shinshuensis), the ridge formula for the species is proposed as follows: 11 -2 -34 , Ml DP4 11 I-4EI M211 -2-4-7 1 1' EI -4-2 M3 1 P 4 -42S-5 Paleohistology of the teeth was also carried out, and some characteristics were clarified. The enamel area is generally composed of prisms with cross section of keyhole shape. No typical ginkgoleaf shaped cross section is observed. It may represent a basic pattern of the enamel structure of


Covalent‐polar semiconductors that show intrinsic 2D vertical polarization present new device opportunities. These materials differ from ordinary ferroelectrics in that they are able to maintain polarization normal to a surface even with an unscreened depolarization field. Identifying phases that exhibit intrinsic 2D vertical polarization is an ongoing challenge. Here the discovery of a new promising phase via computational material design, specifically 2D LiAlTe2, is reported. The design concept is developed from a physical understanding of 3D hyperferroelectric covalent polar semiconductors. A structure determination method combining a swarm intelligence algorithm and first‐principles calculations is used to identify energetically stable structures. In addition to the expected layered version of bulk LiAlTe2, β‐LiAlTe2, a novel 2D structure, γ‐LiAlTe2, is found. In this phase, the vertical dipole can be switched between 0.07 and −0.11 e Å. This switching is triggered by the movement of the Li atom between two local energy minima. The associated asymmetric double‐well energy profile can be continuously tuned by the applied electric field as well as strain. There is, therefore, a reversible transition between two polar states. This discovered off‐plane switchability provides an opportunity for a 2D γ‐LiAlTe2‐ based interfacial phase change memory device; for example, by growing γ‐LiAlTe2/GeTe heterostructures.


I analyze the linguistic picture of the Portuguese emotion saudade, roughly "nostalgia," in an attempt to show its cultural significance and contradict the view that nostalgia is a marginal feeling, deprived of any practical function.


The purpose of this study is to determine the tumor volume threshold for successful positron emission tomography (PET) imaging of melanoma nodal metastases.


Background: The objective of this study was to study the effect of increased adiposity on Ocular Perfusion Pressure (OPP) and its relation with obesity indices. Methods: The study included 82 subjects grouped into two based on their Body Mass Index (BMI) as obese group (n=41) and Normal group (n=41). Blood Pressure was measured using sphygmomanometer. Mean Arterial Pressure (MAP) was calculated. Intraocular Pressure (IOP) was recorded using Schiotz indentation tonometer after anaesthetizing the cornea with 2% paracaine solution. OPP was calculated as 2/3 the MAP minus IOP, Systolic Ocular Perfusion Pressure (SOPP) was calculated by Systolic Blood Pressure minus IOP and Diastolic Ocular Perfusion Pressure (DOPP) was calculated by Diastolic Blood Pressure minus IOP. Statistical analysis was performed using the SPSS version 19. Results: Resting mean SBP, DBP, MAP, IOP, OPP, SOPP & DOPP were significantly higher (p<0.05) in the obese group. IOP, OPP, SOPP & DOPP were significantly positively correlated with all the obesity indices. BMI was the most important individual parameter in prediction of IOP where as WHR & WC was the major predictors for OPP, SOPP and DOPP. Conclusions: The study thus shows that Ocular perfusion pressures were significantly affected by the increase in adiposity in young adults

After identifying the paucity of positioning research relating to political marketing the construct is defined and practical examples of its application in politics provided. The analysis of the 2005 election starts by considering the long term framing of political issues and concludes that this, overall, provided Labour with a competitive advantage. Next the positioning dilemmas facing the three national parties in British politics at the start of the campaign are highlighted. Using a basic positioning model, the positioning strategies followed during the campaign itself are then discussed, both in terms of policies and image/emotional positioning approaches. The attempts by the opposition parties to reposition Labour and the latter's defensive reactions are discussed at this point. Then, the way the wider positioning of the parties was targeted at electoral segments is considered. The paper concludes with an attempt to explain the election result in terms of the relative success or failure of the positioning strategies adopted.


A radiation monitor has been developed that will scan each vehicle leaving the Clinton P. Anderson Los Alamos Meson Physics Facility site. If an increase in radiation level is sensed, an alarm light and a Klaxon horn are activated, inviting the driver to return to the Health Physics office for check. A photograph showing the vehicle license number is also taken. A radiation source that doubles the detector count rate when stationary will cause an alarm at vehicle speeds up to about 24 km/h (15 mph). The technique used to prevent false alarms because of radiations from nearby buildings or from plumes of low-level radioactive gas is described. 9 figs.


Gastrointestinal tract (GIT) infections are major causes of mortality and morbidity world-wide, especially in developing countries. Cajanus cajan extracts possess therapeutic properties. In this study, the induced and non-induced antibacterial properties of C. cajan seeds were evaluated against bacterial strains implicated in GIT infections by Disc diffusion method and Micro-well dilution assay. C. cajan produced phytoalexins after the seeds were elicited with native flora and silver nitrate. At 100 mg/ml, the ethyl acetate extract produced zones of inhibition (14 to 16 mm) against Staphylococcus aureus (ATCC 25925), Klebsiella pneumoniae (ATCC 31488) and Salmonella typhimurium (ATCC 700030). The minimum inhibitory concentration (MIC) values obtained using micro well dilution method were 6.5, 12.5, and 12.5 mg/ml for S. aureus (ATCC 25925), K. pneumoniae (ATCC 4352) and S. typhimurium (ATCC 700030) and 25 mg/ml for all bacterial strains in the ethyl acetate extract (AgNO3 induced seeds), respectively. The results thus indicated that C. cajan seed extract do possess antibacterial activity.

 Key words: Seeds, antimicrobial, phytoalexins, phytoanticipins.


Study Design: Case Report Objective: To present a patient with long-standing TMJ dislocation and pseudoarthrosis in the temporal bone treated with orthognathic surgery and unilateral joint replacement. Method: The patient, a 52-year-old female, came to our department to treat facial asymmetry and oral rehabilitation. The patient reported early facial trauma at 7 years old showing partial edentoulism, dental occlusion class III and a 19 mm mandibular midline deviation. Cone beam computed tomography showed the left TMJ in long-standing dislocation into the fossa temporalis, creating a new articular fossa in the temporal bone and adaptation of the hard and soft tissue. Results: Orthognathic surgery and TMJ replacement using a patient-specific implant and dental rehabilitation were planned; surgery was performed with no complications, and the 1-year follow-up showed that this treatment was a good option for long-standing TMJ dislocation. Conclusion: The long-term TMJ dislocation can be successfully treated by TMJ replacement using a patient-specific implant to obtain facial balance and oral function and avoid relapse.


To compare the performance of the Collaborative Integrated Pregnancy High‐Dependency Estimate of Risk (CIPHER) model in predicting maternal death and near‐miss morbidity (Severe Maternal Outcome [SMO]) with the Sequential Organ Failure Assessment (SOFA), the Acute Physiology and Chronic Health Evaluation (APACHE) II, and the Simplified Acute Physiology Score (SAPS) III scores.


Our understanding of the modelling of Standard Model processes plays an important role for Higgs physics and searches beyond the Standard Model. Measurements such as vector boson plus jet production are essential for the understanding of backgrounds, modelling of double parton interactions, heavy flavour production from gluon splitting and modelling of the underlying event. Precision QCD measurements can also be used to constrain parton density functions, which are important for the understanding of the Higgs boson production cross section and the Standard Model backgrounds at the LHC kinematic limits. A review of recent ATLAS measurements is presented.


This paper reports about fullerenes, its structure, properties and applications. Fullerenes are the third allotropic form of carbon material after graphite and diamond. These were discovered in 1985 consist of 20 hexagonal and 12 pentagonal rings as the basis of an icosohedral symmetry closed cage structure. Each carbon atom is bonded to three others and is sp 2 hybridized. The C 60 molecule has two bond lengths, the 6:6 ring bonds can be considered "double bonds" and are shorter than the 6:5 bonds. C 60 is not "superaromatic" as it tends to avoid double bonds in the pentagonal rings, resulting in poor electron delocalisation. As a result, C 60 behaves like an electron deficient alkenes and reacts readily with electron rich species. The geodesic and electronic bonding factors in the structure account for the stability of the molecule. Fullerenes can be used as organic photovoltaics(OPV), these are powerful antioxidants, reacting readily and at a high rate with free radicals which are often the cause of cell damage or death. Other uses of C 60 like catalysts, in water purification and biohazard protection, portable power, vehicles and medical.
