Our study profiles a varying process of the relationship between delay of gratification (DG) and job performance over time and examines the moderating role of perceived organisational justice in the DG-job performance relationship. Employees' ability to delay gratification was measured during their job interviews (Time 1). When they had worked for 3 months (Time 2), their job performance was rated by their supervisors. When they had worked for 5 months (Time 3), their perception of perceived informational justice was measured. Their job performance was rated again by their supervisors at 6 months (Time 4). The results showed that DG could directly predict new employees' short-term (3-month) job performance but not their longer-term (6-month) job performance. Moreover, perceived informational justice moderated the relationship between DG and 6-month job performance.


While primarily designed for radar studies of the Venus surface, the high effective isotropic radiated power (EIRP) from the Magellan spacecraft makes it an ideal transmitter for use in radio occultation measurements of the refractivity and absorptivity of the Venus atmosphere. Such experiments have been conducted involving transmissions at 2.3 GHz and 8.4 GHz (13 cm and 3.6 cm, respectively), during spacecraft ingress. Since the stability of the spacecraft transmitter is critical for accurately determining the Doppler shift and amplitude attenuation created as the ray penetrates the atmosphere, the spacecraft transmitter was locked to a 2.1 GHz uplink from a 70-meter DSN station which also received the signals. Because of the high directivity of the spacecraft antenna, and the significant ray bending in the deep Venus atmosphere, a spacecraft tracking maneuver was designed to keep the spacecraft antenna pointed in the direction of the refracted ray path back to Earth. This tracking maneuver, plus the high EIRP of the Magellan transmitter has yielded 3.6 cm refractivity and absorptivity profiles down to the 35 km altitude and 13 cm profiles down to the altitude of critical refraction (approximately 33 km). The statistical uncertainties in the derived profiles are significantly lower than those previously obtained, resulting in extremely accurate profiles of H2SO4 (g) abundance as discussed in an accompanying paper.


This paper aims to examine that application of a workshop is effective in the writing education for the intermediate Korean learners. First, it discusses what kinds of characteristics the workshop should effectively utilized to enhance the learners' writing capability in Korean as a foreign or second language. It also investigates what the learners really experience within the lessons initiated by the concepts of workshop, focusing on the changes in their writings in each step. The model of workshop proposed in this study can be defined as a writing-revision programdesigned to help the learners revise their writings based on the idea of mediationof a teacher and peers within a particular educational situation. The effects of this program can be broadly divided by three aspects: cognitive, affective and social. First, the cognitive effect means that learners can acquire a certain level of knowledge in the domain of writing through this program. Second, the affective effect represents that learners might experience the change of attitude toward the writing activities through the mediationof a teacher or peers in this program. Last, the social effect indicates that this program might lead the students to understand and accept various viewpoints of members in a society through the interactions with a teacher and peers. Those characteristics of this program above might facilitate the Korean learners to focus more on the readers beyond the writer-centeredness and to finally produce appropriate texts suitable to the Korean writing conventions.

"The Book of Al Sawad" is the part that Adonis has devoted to Cafour in his famous trilogy: "The Book: Yesterday Place Now, after reviewing Sayf Al Dawla's papers, and the papers of Khawla, to complete the biography of Al Mutanabbi in the book. The recipient's memory has two images for Cafour, paradoxically, two contradictory, the first positive historical witnessed by what was said in the history books, and a satirical poetic picture, Al-Mutanabbi drew it and defined its features, who made his praises in Cafour apparently and inwardly, and what settled in the Arab imagination is the blacks and the black. The researcher in this study seeks to clarify the features of the image that Adonis tried to paint for Cafour in Al Sawad Book, and made it a contrast to that which was mentioned in the history books. Through confessions in which Adonis revealed the most important attitudes in the life of Cafour, and showed his most prominent characteristics, and lifted the veil on the controversial relationship between him and Al-Mutanabbi, which referred praise to stare. The researcher examined the study through a contextual, analytical approach that sees the text in its relations with what is around it and with the world that established it.


Religion is not only a social ideology,a traditional culture mode,but also a substantial social Force.There are three methods to analyse religion infiltration which are reology,politics and sociology.Eliminating the ambiguity,mystery and sensitivity from the mean of religion infiltration can help us to research it as a real academic problem.The practical department will also benefit from it.


The defects of transverse coating ripple and longitude coating ripple on the hot-dip galvalume coating produced by thin slab continous casting-rolling process were analyzed by using OM and SEM-EDS.Comprehensively,air knife-pressure,gap of air knife,angle of air knife,the temperature of zinc liquid,the temperature of steel strip in zinc pot are the main reasons of coating ripple on the galvalume coating.Longitude coating ripple is caused by lower air knife pressure and higher temperature of zinc liquid.Higher air knife pressure and wider gap of air knife lead to transverse coating ripple.The homogeneity coating thickness,spangles and shine can be achieved by means of controlling the process parameters to ensure the shake of strip steel under 3 mm at certain temperatre.


Among US consumers, there is a growing movement in which individuals focus on the development of a more sustainable lifestyle by eating food cultivated close to or at their home. This includes raising backyard chickens for eggs in both rural and urban area. Eggs are a valuable source of many nutrients, and there is an overall perception that eggs from backyard chickens are more nutritious than those obtained from commercial sources. Nutrient concentration in eggs is most strongly influenced by the diet of the hens. Backyard flocks are often fed a varied diet which, in addition to a commercial egg layer feed, may include supplements, scratch grains and kitchen scraps. Hens with outdoor access will also forage for insects and grasses and will intentionally or incidentally eat soil. These factors may result in varied nutrient intake levels. We examined the mineral concentration of the whole edible portion of eggs (yolk and albumen combined) collected from six backyard flocks in the greater Madison, WI area. Diet, nutrient supplementation, outdoor access and outdoor conditions varied among flocks. Concentrations of calcium (Ca), iron (Fe), magnesium (Mg), manganese (Mn), sodium (Na), phosphorus (P), potassium (K), and zinc (Zn) were evaluated using inductively coupled plasma optical emission spectrometry. Analysis of covariance (ANCOVA) was used to compare egg mineral content among flocks. Nutrient intake, outdoor access and outdoor conditions (including soil mineral content) were evaluated as covariates. Significant differences in Ca, K and Mg (p <0.05) were correlated with differences in flock rearing conditions. Egg levels of Fe, Mn, Na, P and Zn did not vary. These data indicate that variability exists in the mineral nutrient content of eggs collected from small backyard flocks. Further research is required to identify husbandry techniques that can be adapted to small backyard flocks, particularly in urban areas, which optimize the nutritional content of eggs.


This article, Part II in a series, reports on the grain refining performance of the Al–Ti–C alloys produced by reactive synthesis. Grain refinement was tested as a function of the following parameters in the reaction synthesis process: Ti content, Ti/C ratio, and cooling rate after the reaction. The grain refining performance of the alloys in the as-synthesized condition was limited due to either a shortage of TiC particles or an insufficient amount of aluminum matrix. Dilution of the alloys to a nominal composition of 3 wt% Ti, followed by extrusion improved the grain refinement to the level of commercially available Al–Ti–C grain refining alloys. A prerequisite for successful secondary processing is that the conversion of carbon is completed in the reaction synthesis; otherwise Al_4C_3 is formed rather than TiC.


This study examined the links between academic and social defensive pessimism and optimism strategies and adolescents'future orientation in two prospective domains: education and military service. Analyses of data collected from Israeli 11th graders indicated (a) the prediction concerning domain specificity was corroborated so that academic strategies were significantly linked to prospective education components, and social strategies to prospective military service components and (b) investment in prospective life-course domains was linked to adolescents'employment of optimistic rather than defensive pessimism strategies. Findings emphasize the optimism underpinning future orientation and the need to distinguish between short-term and long-term effects of defensive pessimism on performance and psychological well-being. It was suggested that defensive pessimism may be positively associated with future orientation are both prospectively directed. Defensive pessimism may facilitate short-term planning and task performance but hinder the motivation to invest in the construction of long-range future orientation.

Existing word similarity measures are not robust to data sparseness since they rely only on the point estimation of words' context profiles obtained from a limited amount of data. This paper proposes a Bayesian method for robust distributional word similarities. The method uses a distribution of context profiles obtained by Bayesian estimation and takes the expectation of a base similarity measure under that distribution. When the context profiles are multinomial distributions, the priors are Dirichlet, and the base measure is the Bhattacharyya coefficient, we can derive an analytical form that allows efficient calculation. For the task of word similarity estimation using a large amount of Web data in Japanese, we show that the proposed measure gives better accuracies than other well-known similarity measures.


In this paper we investigate the effect of global parallelism using a master slave approach, on the behavior of a steady state genetic algorithm for design optimization.


This article identifies common issues relating to management accounting education in order to determine whether using a competency†based approach would assist educators in the design, delivery, and assessment of syllabi at educational institutions. A conceptual framework is developed and discussed with regard to the critical success factors methodology to design syllabi that assist educators in attaining the main outcomes in the delivery and assessment of the curriculum. This framework is applied to a typical management accounting curriculum to demonstrate how this approach will enable educators to design, deliver, and assess their syllabi in line with the critical outcomes required. In following this approach, lecturers would constantly have to focus on the knowledge and issues that are relevant and critical for students to understand and apply in order to achieve the aim of the syllabi.


The phenolic resin based carbon foams were prepared by embedded sintering method for the first time.Phenolic resin was synthesized by the reaction of phenol and formaldehyde using sodium hydroxide as catalyst.The phenolic resin foam was prepared from the phenolic resin mixed with pentane as blowing reagent,Tween-80 as stabilizer,sulfuric acid as curing agent.Then the foam sample was carbonized under 1 050 ℃ buried in carbon and graphite powder to obtain the phenolic resin-based carbon foam.The morphology,crystalline structure and surface area of the resultant carbon foams were characterized by scanning electron microscope(SEM),X-ray diffraction(XRD) and surface area measurement(BET).The results indicate that as-prepared carbon foams are porous carbon materials with very light bulk density,and fine pore structure.The surface areas of the carbon foams are ranging from 350 to 750 m2/g.The structure of carbon foams changes from amorphous to graphite along with the increased carbonization temperature.


une femme (1961), Deux ou trois choses que je sais d'elle (1967), and JLG/JLG – autoportrait de décembre (1995) have two essays dedicated them — not to mention Le Mépris (1963), which has three — important works including Alphaville (1965), Made in USA (1966), Prénom: Carmen (1983), Détective (1985), King Lear (1987), Soigne ta droite (1987), Nouvelle Vague (1990), Hélas pour moi (1993), and For Ever Mozart (1996) barely get a mention, if at all. Scattered in between essays concerned with the films themselves are welcome treatments of theoretical and thematic aspects of Godard's work, including an account of Godard's influence on Bernardo Bertolucci by Fabien S. Gérard, an explication of Godard's reflections on the Second World War and the Holocaust by Philip Watts, Douglas Smith's reference to Godard's often conflicting affinity for both realist and abstract modern art practices, and Thomas Odde's charting of Godard's cinematic use and abuse of oil companies in the 1960s. Godard's concern with the cinematic representation of history in works such as Allemagne année 90 neuf zero (1991), The Old Place (1999), Notre musique (2004) and his magnum opus Histoire(s) du cinéma (1988–98) is the main focus of the latter third of the anthology. However, the highlight of this collection is pre-eminent Godard scholar Michael Witt's 'On and Under Communication', an excellent account of Godard's little-seen collaborative video and television work with Anne-Marie Miéville in the 1970s under the name Sonimage. Most illuminating here is Witt's skilful delineation of Sonimage's embrace of Claude Shannon's communication theory, as outlined in his Mathematical Theory of Communication (Urbana: University of Illinois Press, 1949). While Miéville's contribution is highlighted, it is surprising, in an anthology as lengthy and detailed as this, that there are no essays specifically concerning Godard's collaboration with his first wife Anna Karina, or his second, Anne Wiazemsky. There is also a noticeable lack of criticism from a feminist point of view, save Martine Beugnet's 'Commerce and the War of the Sexes', which rather strangely concentrates on Godard's influence on the films of Laetitia Masson. These minor quibbles aside, it is undeniable that Tom Conley and Jefferson Kline have compiled a significant resource that belongs on the shelf of every Godard scholar.


USIC TEACHING IN THE ELEMENTARY G R A D E S. George E. Hubbard [American Book Company, $2.00]. Not long ago we had musicians who were innocent of any knowledge of education, and educationists who were innocent of any knowledge of music. Now the musicians are studying education; and if they do not learn too much of a kind of education that makes no place for anything that is not perceivable by the physical senses the results will be inestimable. The present book is on middle ground. It represents broad educational thought, but directs its attention chiefly to practical steps that reflect such thought. The author is predominantly progressive. He endorses the "observation method," and, in general, musical experience as the right preliminary to all technical study and drill. His explanations and suggestions for following this method in instrumental music constitute, indeed, one of the best sections in a good book. It may be, however, that for some teachers he descends too soon and too far from broad principles to minutiae of practice. There is always danger, too, that in such process an author may either lose sight of his principles, or else press them to a practical conclusion so remote from the fountainhead of his principles that the virtue of these principles does not carry through. This seems to be the case when, in an endeavor to clear the child's path of technical hurdles, the author counsels the use of pitch-pattern marks dissociated from the staff. Progressive principles do not necessarily imply that particular proceeding. The same tendency -and Yankee rationalistic thought has reveled in it-to ride the steed of principle till it stumbles in far reaches of thick stubble, can be traced in other pages. But even if this be a fault-and to the less informed and experienced teachers it may be quite otherwise-it is balanced by many excellences. From the first to sixth grades, inclusive, every conceivable principle, problem, method, and device that should concern the teacher of music is discussed fully, clearly, conclusively. Besides four chapters that deal with the grades in order, there is an excellent Foreword by Dr. Stringham, a notable Introduction by the author, and chapters on The Teacher; The Training of the Supervisor; Solmization, Ear Training, and Key Signatures; The Teaching of Instruments; Tests and Measurements; and Music Appreciation. A short Appendix entitled Suggested Methods for Music Appreciation holds more good counsel than many pronouncements twice as long. Most admirable, too, are Suggestions for Discussion, as well as a list of Suggested Readings, which are placed at the end of each chapter. An index completes the admirable provisions for making all the values the book possesses quickly and easily available. ---Will Earhart


Hemmelgarn, Glisson, and James (2006) provide an excellent review of the impact of organizational culture and climate for the implementation of evidence-based practice (EBP) models within social and mental health services systems. As their article makes clear, the implementation process should address the organizational context, and effectiveness and services research should consider organizational factors in outcome and EBP transport research. This commentary extends discussion of one aspect of organizational culture—the extent to which organizations are driven by an empirical scientific epistemology—and how this may contribute to establishing a context for EBP design, selection, implementation, and sustained evolution in field settings.


This study explores how task engagement principles could be integrated into the design of online foreign language and culture instruction. It employs a design-based research (DBR) approach, which combines research and instructional design during curricular development. With the intent of solving problems of practice in an existing teaching context, a design team worked in this study to refine an online Chinese as a foreign language and culture module. Through the design process, the team explored how task engagement principles could be integrated into seven online language-learning units and how collaboration and interaction among the researchers and designers could support the implementation of the design. This study underscores the importance not only of designing engaging online language tasks but also of working with expert others to accomplish this goal.

Epidural Pneumatic Pseudocyst with Lumbar Radiculopathy: Two Case Reports and Review of the Literature


Objective
To investigate the assessment and influencing factors of the cerebrovascular function in 40-60 years old women in Guiyang city, and to provide information for the prevention of stroke in menopausal women.

Methods
Self-designed questionnaire was used among randomly selected healthy women aged 40-60 years who received health checkup from April 2016 to April 2017 in the Medical Examination Center of Affiliated Hospital of Guizhou Medical University. Levels of height, weight, blood pressure, blood lipid, blood glucose, blood uric acid and the cerebral hemodynamics were checked, comparing the influence of different factors for cerebrovascular function integral value differences, and assess the risk of stroke.

Results
A total of 439 cases were included in the study, the number of cases with abnormal cerebro vascular function (the score of cerebro vascular function score <75) accounted for 13.2% (58/439) . Increased age, being ethnic minorities, menopause, obesity, high blood pressure, high blood sugar, high blood uric acid, increased high-density lipoprotein cholesterol (HDL-C), total cholesterol and triglycerides were related to the abnormal scores of brain function, and the difference was statistically significant (P<0.05). Logistic regression analysis indicated that minority, High HDL-C [OR(95%CI): 0.38 (0.25-0.58), P=0.036], obesity [OR(95%CI): 11.62 (5.17-26.14), P=0.001] and hypertension [OR(95%CI): 14.87(2.46-89.75), P=0.001] are the factors influencing the cerebro vascular function.

Conclusion
The proportion of abnormal cerebrovascular function was 13.2%. Increased HDL-C is the protective factor for perimenopausal cerebro vascular function. Minority, obesity and high blood pressure are risk factors for cerebro vascular function, of which, the association between hypertension and cerebro vascular function worsens with elevated blood pressure.

Objective: To compare preand postoperative outcomes in patients who underwent transmastoid plugging of a superior semicircular canal dehiscence. Design: Retrospective cohort study Setting: Subjective as well as objective outcomes in patients with superior semicircular canal dehiscence plugged using the transmastoid approach between 2012 and 2015 in Radboud University Medical Centre. Main outcome measure: The vestibular signs, auditory signs, dizziness handicap inventory (DHI) questionnaire, cervical vestibular evoked myogenic potential test (cVEMP), pure tone audiogram, speech audiogram and electro-nystagmography were documented. Results: In total 13 patients were included for analysis, with a mean age of 52.7 years. Nine patients received preand postoperative cVEMPs, showing a significant postoperative increase of cVEMP thresholds. In seven patients, preand postoperative DHI scores were available showing a significant decrease of their dizziness handicap. No significant pre-postoperative differences were found for all other audio-vestibular tests. No serious complications occurred, and the mean hospital stay was 1.4 day. Conclusion and recommendation: Transmastoid approach for plugging the dehiscence of the superior canal resulted in significant improvement of cVEMP thresholds and DHI scores. Plugging the dehiscence using the transmastoid approach is recommended, since it is associated with a short hospital stay and low rate of adverse events. *Correspondence to: Andy J Beynon, Department of OtolaryngologyHead and Neck Surgery, University Medical Center Nijmegen, Philips van Leydenlaan 15, 6500 HB Nijmegen, The Netherlands, Tel: +31243614965, Fax: +31243540251; E-mail: firstname.lastname@example.com


In many countries of the world, we are observing a revival of federalism. Whether this development should be called a "worldwide federalist revolution" (Daniel Elazar) is a matter of opinion. In any case, contrary to what Harold Laski predicted, neither big government nor the welfare state has made federalism obsolete. The concept of federalism covers a wide variety of patterns of government, all of them being rather complex due to their compound nature. Therefore, comparative studies on federalism are of considerable relevance. The Forum of Federations and the International Association of Centers for Federal Studies (IACFS) are engaged in supporting comparative research on federalism and in transferring knowledge to practitioners in federal and federalizing countries. Part of their efforts is the series "A Global Dialogue on Federalism". The volume reviewed is the first book about the constitutional frameworks of federal governments, while the subsequent volumes (six are currently available and there are more to come) provide information about particular features of federalism. This volume includes twelve country reports. They were written by experts on the respective federal state. Following a thematic template and working procedure elaborated by the editors, the authors not only reviewed the literature, but also consulted scientists and practitioners in their countries. Supported by competent editors, the authors produced rather coherent, well-structured chapters presenting constitutional experiences in federal democracies. The general framework, introduced by G. Alan Tarr, defines a constitution as "a society's fundamental choices about governments" (p. 8), and lists the typical elements of a federal constitution like the designation of the component units, allocation of power and finances, procedures of intergovernmental co-ordination, institutions of government, citizenship and individual rights, which are all dealt with in the country reports. The concept of a constitution guiding the volume goes beyond a narrow understanding focused on written documents and includes the 'living' constitution. Each country report gives an account of the interplay between federalism and different types of democratic government, varying between presidential and parliamentary systems and including what German scholars call "defective democracies". Most authors also explain the dynamics of intergovernmental relations evolving in a more or less constitutionalized framework. They not only describe the rules determining the allocation of powers, but also analyse the limits of these rules and tendencies towards centralization and decentralization, which are fostered by tensions between individual rights and claims by territorial minorities or by the rise and decline of


The concept and relation of continuity and dispersion are analyzed,and the features of continuity and dispersion in a model of liquid medium are discussed.


Physical performance tests are objective measurements of the functional state of the elderly, and their effectiveness has been demonstrated to identify who of them are more susceptible to disability. The advantages of implementing these tests in the geriatric clinical practice are exposed in this work, which are feasible in any scenario, even with few resources conditions, due to their simplicity, reproducibility and low cost; so that they can be more used to stratify the disability risk in aged patients of any community.


Interdisciplinarity: easy to like, hard to do. (And to pronounce.) Despite decades of university rhetoric urging interdisciplinary scholarship, it remains an elusive and widely misunderstood objective. 'Everyone wants interdisciplinary research but very few understand how it is produced', as Claire E.F. Wright puts it in her debut monograph (2). In Australian Economic History, Wright sets out to examine the structures and conditions that enable (or not) interdisciplinary research, through the example of economic history – one of the oldest interdisciplinary fields. Over six chapters, Wright tracks Australian economic history from its origins with statistician Sir Timothy Coghlan in the late nineteenth century, to the twenty-first-century resurgence of interest in the material dimensions of the past – a revival that has produced 'new histories of capitalism' both here and overseas. Australian Economic History is almost two books in one: both a chronological history of the field of Australian economic history and an analysis of interdisciplinary knowledge production written with an eye to university policy. While the latter will be of great interest and relevance to anyone working in higher education, the former has a more niche appeal. The introduction and conclusion foreground the question of interdisciplinarity, yet the substantive chapters at times drift deep into the weeds of economic historiography – a hangover, perhaps, from the more empirical PhD that formed the basis of this book. That said, both the history and analysis are carried off with aplomb – no mean feat, given that the book (minus references and appendices) comes in at a slim 190 pages. Wright is not the first to tell the story of economic history in Australia, with the topic canvassed in various articles over the years. But in this pioneering book-length study of the topic, Wright presents a revisionist history that challenges the accepted 'rise and fall' narrative. The conventional story goes like this: after early forays in the interwar period, there was a postwar explosion in economic history, led by the 'great man' Noel Butlin, who founded the 'orthodox' school based at the Australian National University (ANU). As higher education expanded, economic history departments proliferated. By the 1980s, there was a peak of 50 dedicated economic historians nationwide. Then, in the wake of the Dawkins reforms, and the rise of the neoliberal university, the 'departmental era' collapsed. Student numbers plummeted, departments closed, retiring academics were not replaced. The few remaining


Image registration is a significant assignment in computer visualization and medical imaging, which involves aligning two or more descriptions of the same division or object taken from different viewpoints or at dissimilar epochs. Deep learning-based approaches have recently demonstrated promising outcomes in several image-processing applications, including image registration. Using multi-scale feature extraction methods and deep learning, the study provides a reliable image registration method in this study. Three primary steps make up the suggested method: feature extraction, feature matching, and transformation estimation. A deep convolutional neural network (CNN) is utilized in the feature extraction process to extract multi-scale information from the input images. The CNN architecture is built to manage large-scale deformations by extracting features at various scales. Following feature extraction, a strong matching technique based on the nearest neighbor distance ratio test is utilized to match the extracted features. The proposed method uses the Random Sample Consensus (RANSAC) algorithm to estimate the transformation parameters robustly, which helps to handle outliers and noise in the feature-matching process. The proposed method is assessed on several benchmark datasets, including the ETH-80 dataset and the TUM RGB-D dataset, and compared with state-of-the-art approaches. The investigational consequences demonstrate that the proposed method outstrips prevailing approaches in terms of accuracy and robustness, especially for images with large-scale deformations. The proposed technique also demonstrates good performance in the presence of noise and outliers, which further demonstrates its robustness.


The main technical parameters of the luggage car exported to Korea as well as the structure features of the various parts are described briefly. The design thought of the steel structure of the car-body is expounded. The strength and rigidity of the car-body steel structure can be improved by improving the strength and rigidity of the underframe and roof. The static strength test has proved its reasonability.


Objective To discuss the influence of clean-up frequency of the operative cavity on the curative effect after endoscopic sinus surgery.Methods 368 patients with sinusitis or nasal polyps were randomly divided into observation group and control group,184 patients in each group.Control group was treated with operative cavity cleaning in moderate frequency,while observation group in intensive frequency.Results The obvious effective rate of observation group was 80.98%,which was significantly higher than that of control group(69.02%) (x2 =12.468,P <0.05).The ineffective rate of observation group was 2.17%,which was significantly lower than that of control group (9.78%) (x2 =15.717,P < 0.05).The recurrence rate of observation group was 11.96%,which was significantly lower than that of control group (26.09%) (x2 =9.361,P < 0.05).Conclusion The clean-up frequency of the operative cavity after endoscopic sinus surgery can influence curative effect,moderate clean-up frequency can significantly improve the treatment effects and deserved promotion.

The superior swimming ability of fish has encouraged the development of fish-like robots. To fully capture fish swimming kinematics a continuum under-actuated robot can be used, and there are many examples of such robots in the literature. But for realistic fish-like swimming in strong currents such robots will benefit from closed-loop feedback. We demonstrate how this can be achieved, underwater, using a stretchy neoprene sensing skin with embedded, discrete dielectric elastomer stretch sensors. The latest prototype skin, with 8 sensors, 4 on each side, is currently being evaluated on an underactuated tensegrity fish-like robot driven by a stepper motor. Carangiform movement of the body has been characterized using cameras and this data has been compared with a virtual model of the robot that uses sensor input for real-time model kinematic data. Four angles along the body defined the shape. A root mean square error between model and true camera angles of less than 3° was calculated for realistic cangiform motion at 0.5 Hz tail frequency.


In the paper the role of an initial object is played by a couple (L,L0) of closed linear relations in a Hilbert space H, such that L0 ⊂ L. Each closed linear relation L1(M1) such that L0 ⊂ L1 ⊂ L (respectively L∗ ⊂ M1 ⊂ L0) is said to be a proper extension of L0(L). In the terms of abstract boundary operators i.e. bounded linear operator U(V ) acting from L(M) to G (G is an auxiliary Hilbert space) such that the null space of U(V ) contains L0(L ∗), criteria of mutual adjointness for mentioned above relations L1 and M1 are established.


The tissue specificity of the expression of the hepatitis B surface antigen (HBsAg) in transgenic mice was studied. Northern blot hybridization and electron microscopy of various tissues revealed the higher HBsAg transcription levels confined to the liver and kidney, and to a lesser extent to the spleen and intestines. In electron microscopic studies we found HBsAg particles in the serum of transgenic animals to be positive by ELISA to HBsAg. The expression of the transgene was localized in situ in the ovary, liver, kidney, and spleen of transgenic mice, employing a polyclonal antiserum directed against the HBsAg and conjugated with protein A-gold. Surprisingly, F1 transgenic females from the CB-104 line, expressing HBsAg in the serum, showed impaired fertility, although the ovarian function was not diminished. Normal off-spring were obtained after cross embryo transfer between transgenic (Tg) females to non-transgenic (Ntg) recipients or from Ntg embryos transferred to Tg recipients. We speculate that this phenomenon could be related to a disruption on a gene(s) somehow involved in the reproductive performance of the transgenic females.


Floral morphology of Artemisia annua L. was described using light and scanning electron microscopy. Floral trichomes include nonglandular T-shaped filamentous trichomes, which occur on the basal bracts and pedicel of the capitulum, and 10-celled biseriate glandular trichomes on receptacle and bracts of capitula and corolla of florets. The heart-shaped biseriate glandular trichomes, composed of two columns of five cells each, are similar to those described for the leaf. During floral development, the cuticle surrounding the apical cells of biseriate glands detaches and forms a saclike reservoir for fluids excreted by the apical cells. The cuticle ruptures at anthesis, discharging its contents on the inflorescence. Artemisinin was detected by HPLC-EC from flowering branches dipped for 60 s in petroleum ether or acetonitrile, providing corroborating evidence that biseriate glandular trichomes were the likely site of artemisinin sequestration.

In this paper, we have constrained the cosmological parameters of Bianchi type V universe by bounding the model under consideration with recent observational [Formula: see text] and Pantheon data. It is assumed that the energy conservation law holds separately for barotropic fluid and dark energy fluid i.e. dark energy component does not interact with barotropic matter. We obtain the present value of deceleration parameter and age of universe as [Formula: see text] and 13.329 Gyrs respectively. The analysis of [Formula: see text] and jerk parameters concur that the derived model approaches [Formula: see text]CDM universe at late time. We find that estimated values of Hubble's constant and energy density parameters have pretty consistency with their corresponding values, obtained by recent observations of WMAP and PLANCK collaborations. It is also observed that the universe shows signature flipping from decelerating to accelerating phase for transitional red-shift value [Formula: see text] in past.


In the present work the combination of bioactive glass ( BG) and cordierite are expected to produce high strength bioceramic. Both BG and cordeirite powder were synthesized by melt quench method, then, BG-cordierite composite scaffold was fabricated using gel casting method. The composition of cordierite were varied (10-30 wt.%) during the fabrication of BG scaffold and sintered at 1000°C. The density of BG-cordierite scaffolds were characterized using Archimedes method, while compressive strength was characterized using Universal Testing Machine. The density of BG increase from 0.081 g/cm3 to 0.531 g/cm3 and the compressive strength increased from 0.13 MPa to 0.48 MPa when 20 wt. % of cordierite added to the BG, however compressive strength decreased to 0.36 Mpa whe 30 wt.% added. BG-cordierite scaffolds were immersed in Hank's Balanced Salt Solution (HBSS) for bioactivity test and then were characterized using Scanning Electron Microscope (SEM) and Fourier Transform Infrared Spectroscopy (FTIR). The apatite formation was observed after the immersion of BG in HBSS after 14 days and the amount of apatite present increased with increasing cordierite content in the BG.


There is growing interest in the energy consumed by computer systems, for both individual (battery life) and environmental (global warming) reasons. Multicore architectures offer a potential opportunity for energy conservation by allowing cores to operate at lower frequencies. Previous work on analyzing power consumption of multicores assumes that all cores must run at the same frequency. However, new technologies, such as fast voltage scaling and Turbo Boost, allow cores to operate at different frequencies. In this paper, we present an energy-aware resource management model, ROT-MCP, which provides a flexible way to analyze energy consumption of multicores operating at non-uniform frequencies. This information can then be used to generate a energy-efficient schedule for execution of the computations - as well as a schedule of frequency changes on a per-core basis - while satisfying performance requirements of computations. Experimental results show that the energy savings achieved using this approach far outweigh the energy consumed in the reasoning required for generating the schedules.


We investigate the essential spectrum of the Pauli operators (and the Dirac and the Schrodinger operators) with magnetic fields on the Poincare upper-half plane. The magnetic fields under consideration are asymptotically constant (which may be equal to zero), or diverge at infinity. Moreover, the Aharonov–Casher type result is also considered.

Abstract. In this paper first it is shown for several geometries that classical simila r ty solutions for particle growth exist if and only if the Stefan problem is well-pos ed in the sense of being mass conserving. The extension of the similarity solution s to multicomponent alloys, which makes the problem nonlinear, is illustrated by the a pplic tion to a hypothetic alloy with realistic input values. The similarity solutions are based on the assumption of local equilibrium at the interface. In the second part, the assumption of local equilibrium is relaxed using a first-order interface reaction. The influence of the interface reaction on the movement of the interface and on the interface c onc ntrations is evaluated using Finite Difference calculations. A Newton scheme is used to solve the nonlinear problem.


Objective: To determine prevalence of adrenal insufficiency in catecholamine-resistent pediatric shock; and to study association between serum cortisol level and severity of illness in catecholamine resistant pediatric shock. Study design: Prospective observational study Setting: Pediatric intensive care unit in a tertiary care hospital. Patients: 114 pediatric patients with catecholamine refractory shock. Interventions: Serum cortisol and outcome parameters of mortality, vasoactive inotropic score, Pediatric Risk of Mortality Score and mechanical ventilation rate were recorded. Results: The prevalence of adrenal insufficiency in our study was 14.03%. Mortality as primary outcome variable was significantly correlated to age (0.737), weight (0.291), adrenal insufficiency (0.354), Pediatric Risk of Mortality Score (0.677), and vasoactive inotropic score (0.268). Increase in age, higher incidence of adrenal insufficiency and Pediatric Risk of Mortality Score were associated with the highest odds of dying with 13.7(95% CI, 0.2-943), 2.36 (95% CI, 1.86-2.82) and 1.47 (95% CI, 1.16-1.86) respectively. Overall, the outcome variables were significant in patients with adrenal insufficiency and those with unusually high adrenal cortisol response. Conclusion: We concluded, adrenal response is varied in a wide spectrum of disease conditions in critically ill children. Both low and abnormally high cortisol response to acute illness is associated with poor clinical outcome in the form of high mortality, increased need for catecholamines and higher rates of mechanical ventilation.

Fashion industry constantly produces and consumes, which leads to huge waste piles of perfectly usable textiles in landfills, as well as other negative effects of an exploitative and excessively rapid fashion process. Pollution created by making and dyeing clothes has pitted fashion industry and environmentalists against each other. In this context, upcycling is seen as an optimal way to solve the growing problem of waste in fashion industry. The first purpose of the study was to analyze the relationships between upcycling fashion products' perceived value, pro-environmental beliefs, attitudes, electronic word of mouth (eWOM) intention, and purchase intention. The second purpose is to verify the difference of perceived consumption value among the consumers' awareness level and purchase experience. A total of 258 valid responses obtained from a group of 20-30-year-old participants were collected through an online survey. SPSS 23.0 and Amos 18.0 programs were used for data analysis. The results of the present study suggest that there are significant effects of upcycling fashion products' perceived value on pro-environmental belief; furthermore, pro-environmental belief was found to positively influence attitude, eWOM intention, and purchase intention. In addition, there are differences of perceived consumption value among the consumers' awareness level and purchase experience. Taken together, the results of this study provide researchers and practitioners with a deeper understanding of consumers' values, beliefs, attitudes, and behavioral intentions towards upcycling fashion products.


We propose a new method to improve the design of electro- optical imaging system using an end-to-end model of the imaging system and a combination of image quality criteria. Firstly, we used an imaging system simulator to produce an output image, which is the distorted version of the input scene. Secondly, we calculate an objective quotation for the quality of the imaging system for each parameter set, and compare the results with the human evaluation of image quality. It allows us to calibrate our imaging system quality measure (ISQM). Finally, the ISQM is used as a tool to improve system design without any human observer evaluation.

certain system requirements and expectations may need to be modified because of the inclusion of COTS Commercial Off The Shelf (COTS) products are being products into that system. As COTS products continue considered for inclusion in ever more complex and to be considered as candidates for inclusion within critical systems. There are known advantages and risks Mission Critical systems, there will likely be additional [1, 4, 5] for considering the use of COTS in complex risk factors that will be identified, and there will likely systems. Yet, given the rigorous needs of Mission be improvements to the impacts of known risks to Critical systems or subsystems, there have begun to existing COTS risk factors. The continued pursuit and emerge concerns and risks about the suitability of COTS dissemination of such COTS risk factors will influence for such applications. This paper identifies some of the how both acquirers and suppliers decide if and/or when characteristics of Mission Critical systems (e.g. to use COTS products. Ongoing monitoring of this reliability, availability, correct functionality) that makes technology area, including both benefits attained and the selection process of COTS products (hardware, risks identified, seems to be warranted. In addition, software, subsystems, etc) an increasingly important validation of the mitigation techniques proposed in this factor in total system lifecycle phases (design, paper is warranted, along with collecting lessons learned development, acceptance, operations/maintenance and from projects, which may be experiencing such impacts, disposal). This paper presents a set of risk areas related and those that may have identified additional mitigation to the use of COTS, in general, and specifically for techniques. Mission Critical systems, that would assist both the


Purpose: This study analyzed the bibliometric characteristics of flipped classroom publications in the Social Science Citation Index and Science Citation Index Expanded from 2000 to 2019. Methods: The terms related to "flipped classroom" and "inverted learning" were the keywords for searching journal articles on January 3, 2020. Results: There are 645 articles (including 33 early-access articles), representing 1,938 authors in the 210 journals scanned. The United States, China, and Taiwan were three leading countries/regions in this field. In the top 10 countries, to 10 institutions, the top eight most-cited journals were identified by either the number of publications or the number of citations. Hot-spot themes from the 24 highly-cited articles and author keyword co-occurrence analysis focus on empirical research in the flipped classroom, the overall feasibility of the flipped classroom course design and practical model, and students' performances, and student-regulated learning (active learning and readiness) outcomes. Conclusion: TThe results indicate that the United States dominated flipped classroom research, originating most of the highly-cited articles, having more prolific authors, and presenting the most-cited institutions. Furthermore, little research has been undertaken into arriving at an understanding of evidentiary effectiveness or consistency in a flipped classroom. Based on the trends identified, we need a call for more specific types of research into the effectiveness of flipped classroom studies and systematic reviews.


The principal aim of this paper is to present a new proof of Weyl's criterion in which it is shown that the natural framework for the associated Sturm-Liouville operators is W 2,1 ∩ L 2 -i.e.- the intersection of a particular Sobolev space and of the L2 space. Indeed, we will deal with the special case of the radial operator − d 2 dx 2 + q ( x ) on a real line segment (either bounded or unbounded) that often occurs in the study of quantum systems in central potentials. We also derive from first principles the functional behaviour of the coefficients for a general second-order Sturm-Liouville operator by using some extensions of a milestone Carathéodory existence theorem.


The arguments used to predict the characteristics of primordial galaxies were first reviewed briefly. Actual problems in observing very faint objects are then explained by summarizing the nature of the foreground atmospheric emission. Some of the classical ingenious attemps to lower the upper limit of the integrated light from extragalactic background or to evaluate its spatial fluctuation were reviewed. Recent works using CCDs to image extremely faint objects were reviewed and the cosmological implications of these observations were summarized. It was, however, emphasized that there is as yet no common understanding as to what a primordial galaxy would look like. Importance of 8m class telescopes with high observing capability at near infrared band was stressed to promote observational studies on formation and evolution of galaxies

In the eastern part of the Western Srednogorie Unit, a specific succession of Gintsi and Glozhene–Slivnitsa formations has provided micropalaeontological evidence of late Tithonian (Chitinoidella and Praetintinnopsella zones) and mid-Berriasian (Elliptica Subzone of the Calpionella Zone) age on the basis of 38 chitinoidellid and calpionellid species. A significant stratigraphic hiatus has been documented within the Glozhene–Slivnitsa Formation since the Crassicollaria Zone, as well as the Alpina+Remaniella subzones of Calpionella Zone, are absent from the section. The conformably overlaying Salash Formation is of mid-Berriasian age (Elliptica Subzone) and is locally characterized by presence of calcareous sandstones. Seven carbonate microfacies have been determined, which suggest that the carbonates were deposited in carbonate ramp rather than under pelagic conditions. Indeed, the upper part of the sections studied has revealed an upward-deepening trend.


This paper proposes a robotic simulator for horseback riding that incorporates a crank mechanism with a variable radius. In horseback riding simulations, it is necessary to efficiently generate vertical sinusoid motion. A novel crank mechanism is proposed to change the unidirectional rotation of a motor to sinusoid wave motion with an arbitrary magnitude and frequency. On the basis of the results of a kinematic analysis, the singularity and redundancy issues of the system are presented. To avoid the singularity problem, an inverse kinematics solution is presented and the result of the simulation shows stable solution of the inverse kinematics.


We compared the medical and financial cost‐effectiveness of prenatal serum screening for Down's syndrome using maternal age, serum alpha‐fetoprotein and human chorionic gonadotrophin with and without the use of unconjugated oestriol. The use of unconjugated oestriol is medically more cost‐effective than screening without it at all levels of detection. The actual performance depends on whether gestational age is estimated using 'dates' or an ultrasound scan. At a detection rate of 60 per cent, the proportion of unaffected fetal losses per case diagnosed at amniocentesis is about 22 per cent less if gestational age is estimated using dates (time since the first day of the last menstrual period) and about 47 per cent less if it is based on an ultrasound scan examination. At this detection rate, the inclusion of unconjugated oestriol increases costs by about £2k per case diagnosed (£36k instead of £34k) if gestational age is estimated using dates, but it is no more expensive if gestational age is measured from an ultrasound scan examination (indeed, it is more cost‐effective at detection rates above 60 per cent). Since there is little change in the financial cost with the inclusion of unconjugated oestriol, for the improved medical performance of screening, it is worthwhile including it in the screening test.


In the second of three articles, Angus Thompson continues his reflections on the differences in prescribing and medicines management between the UK and Australia, this time looking at prescription costs, quantities and generics.


Although antiplatelet therapy is usually continued throughout the perioperative period of carotid endarterectomy to reduce the risk of recurrent stroke and other cardiovascular events, individualization still has not been standardized. To evaluate the relationship between preoperative antiplatelet agents and platelet aggregability, we analyzed 42 patients who underwent carotid endarterectomy from August 2005 to May 2006 in our institute. Among the 42, 19 were treated with aspirin alone, 5 with ticlopidine alone, 2 with cilostazol alone, 12 with aspirin and ticlopidine, 3 with aspirin and cilostazol and 1 with aspirin, ticlopidine, and cilostazol. Platelet aggregation in response to platelet agonist was measured in platelet-rich plasma obtained from the brachial vein 2 days prior to surgery. 1 μM and 10 μM ADP, or 2 μg/ml and 5 μg/ml collagen were used as agonists. Aggregation in response to appropriate agonist was inhibited in 73% of the aspirin group and 80% of ticlopidine group. None of the cilostazol group showed effects on aggregability. Patients were divided into 2 groups according to their preoperative platelet aggregability: inhibited (n=3) or non-inhibited (n=39). Intraoperative blood loss was 169.0±23.3 g (144-190 g) or 45.5±31.2 g (9-164 g), respectively. Operation time was 221.7±53.5 min (160-255 min) or 147.3±20.6 min (115-205 min), respectively. The main reason for blood loss and prolonged operation time was oozing from connective tissue. Aggregability in older patients who received multiple antiplatelet agents tended to be inhibited excessively. Taken together, preoperative analysis of platelet aggregability could be useful to reduce the risk of perioperative complication.


State-of-the-art design of analog and radio frequency integrated circuits is often accomplished using sizing optimization. In this paper, an innovative combination of principal component analysis (PCA) and evolutionary computation is used to increase the optimizer's efficiency. The adopted NSGA-II optimization kernel is improved by applying the genetic operators of mutation and crossover on a transformed design-space, obtained from the latest set of solutions (the parents) using PCA. By applying crossover and mutation on variables that are projections of the principal components, the optimization moves more effectively, finding solutions with better performances, in the same amount of time, than the standard NSGA-II optimization kernel. The proposed method was validated in the optimization of two widely used analog circuits, an amplifier and a voltage controlled oscillator, reaching wider solutions sets, and in some cases, solutions sets that can be almost 3 times better in terms of hypervolume.


The notion of information infrastructures, introduced in the 1990s and refined during the past ten years, has proven quite fruitful to the IS field. It changed the perspective from organizations to networks and from systems to infrastructures, allowing for a global and emergent perspective on information systems. However, something is missing in this theory. What is an information infrastructure, ontologically? Is it a technical structure, an organizational form, an analytical perspective or a semantic network? This paper reviews the socio-technical origins of information infrastructures. Two propositions are described and discussed. First, that it is fruitful to regard information infrastructure as an ICT-based organizational form. Second, a critical realist view allows us to conceptualise the object of study in a simpler and more intuitive way. A case study of an airline company and a reinterpretation of Star and Ruhleder's classic paper were used to illustrate the claims.


My first encounter with a quality assurance auditor is reminiscent of an old Dodge commercial. You remember The old sheriff, masked in mirrored sunglasses, paunch hanging over his gun belt, prophesying, You're in a heap o' trouble boy '' Well, my auditor could have been kin to the sheriff; they had the same posture, attitude, and mirrored sunglasses. Plus, my auditor wore a black leather vest and sported a Buffalo Bill'' goatee. While certainly memorable, both gentlemen were far from pleasant. I'm fairly certain that the compliance auditor of old deserved this perceived association with his law enforcement counterpart. Both believed in enforcing the letter of the law, or their interpretations of it. Neither seemed capable of exercising interpretive powers, but instead relied on winning through intimidation, possibly with an eye toward claiming some version of a monthly Quota Award. Is the auditor of today any better perceived Because this first encounter of the worst kind'' made a lasting impression on me, I have dedicated considerable time and effort trying to avoid being perceived as another sheriff when I conduct audits. In my auditing career, I am determined to capitalize on each opportunity to turn negative situations, as experienced bymore » the auditee, into meaningful opportunities for improved performance. I want to treat the auditee the way I want to be treated when I am being audited. (author)« less


Neural networks based on Long Short-Term Memory (LSTM) are widely deployed in latency-sensitive language and speech applications. To speed up LSTM inference, previous research proposes weight pruning techniques to reduce computational cost. Unfortunately, irregular computation and memory accesses in unrestricted sparse LSTM limit the realizable parallelism, especially when implemented on FPGA. To address this issue, some researchers propose block-based sparsity patterns to increase the regularity of sparse weight matrices, but these approaches suffer from deteriorated prediction accuracy. This work presents Bank-Balanced Sparsity (BBS), a novel sparsity pattern that can maintain model accuracy at a high sparsity level while still enable an efficient FPGA implementation. BBS partitions each weight matrix row into banks for parallel computing, while adopts fine-grained pruning inside each bank to maintain model accuracy. We develop a 3-step software-hardware co-optimization approach to apply BBS in real FPGA hardware. First, we propose a bank-balanced pruning method to induce the BBS pattern on weight matrices. Then we introduce a decoding-free sparse matrix format, Compressed Sparse Banks (CSB), that transparently exposes inter-bank parallelism in BBS to hardware. Finally, we design an FPGA accelerator that takes advantage of BBS to eliminate irregular computation and memory accesses. Implemented on Intel Arria-10 FPGA, the BBS accelerator can achieve 750.9 GOPs on sparse LSTM networks with a batch size of 1. Compared to state-of-the-art FPGA accelerators for LSTM with different compression techniques, the BBS accelerator achieves 2.3 ~ 3.7x improvement on energy efficiency and 7.0 ~ 34.4x reduction on latency with negligible loss of model accuracy.


Missional integrity and contextual relevance The research problem addressed in this article discussed whether so-called missional local churches too often escape local contextual involvement by sending money or even people to work on their behalf 'elsewhere'. Is it true that local churches take the easier 'money-way' out to save a missional public face? The hypothesis is that missional integrity is in essence to be 'firstly' contextual relevant 'before' being nationally and even globally involved in mission. A basic assumption is that every local church is a gift of God to a specifically and even geographically defined context.


Infertility is a common condition affecting one in six couples of childbearing age. In approximately 40% of these cases, a male factor is involved. Sperm DNA integrity is essential for accurate transmission of genetic information. Materials and Methods: In this study 152 patients, 64 patients it is infertility group and 88 patients are fertile males. The ejaculate samples were taken in accordance with the patient to whom the reason for the analysis of the ejaculate sample was previously explained. All patients have been in the Dukagjini Region in the Republic of Kosovo. The samples were collected from 2016/18. Sperm Chromatin Dispersion (SCD) test, analysis in the ejaculate was performed at the Biolab Zafi, Laboratory in Peja, in the Republic of Kosovo. Statistical analysis: Data are reported as mean ± SD. The comparisons between groups were tested by student's t-test, ANOVA. A p-value less than 0.05% was considered statistically significant. Results: From our research studies, we have achieved significant (p <.00001) scores among the working group and control group across all sperm parameters, and DNA fragmentation. Conclusion: In summary, we have demonstrated that there was a negative correlation between DNA fragmentation, sperm motility, and morphology in infertile males. We conclude that sperm DNA fragmentation appears to be a useful technique to predict outcome in couples undergoing IVF/ICSI. To evaluate whether DFI 23.94 ± 4.68% can be used to determine male infertility in our country by Sperm Chromatin Dispersion (SCD), it is necessary to carry out further large-scale research by other authors.


The experimental study in this paper focused on the combustion wave temperature measurement and the qualitative observation of phenomena involved in the combustion of a high-metal magnesium-based hydroreactive fuel strand, using a pressure-regulated test combustor. An experimental system was designed and experiments were carried out in both argon and water vapor atmosphere. Two types of hydroreactive fuel were investigated: one containing 60% magnesium particles and the other one containing 73% magnesium particles. Thermal-wave structures of the combustion wave of the hydroreactive fuel were measured by an imbedded type-K fine-wire thermocouple. The surfaces of fuel samples quenched by rapid depressurization were examined in a scanning electron microscope. The chemical composition on the burned surface of the hydroreactive fuel strand was determined by X-ray diffraction analysis. The experimental phenomena implies that magnesium particles in the 60% magnesium fuel are ejected into the gas phase and combus...


Abstract. A multi-user visible-light communication (VLC) system based on 4  ×  4 multiple-input multiple-output (MIMO) was investigated. The system consists of four light-emitting diodes (as a transmitter) and four photodetectors (as a receiver). The proposed system was simulated for two, three, and four users. The objective of this study is to optimize the system power consumption and to utilize the sum rate on the system coverage area. By expanding the system from a 2  ×  2 MIMO-VLC to a 4  ×  4 MIMO-VLC, the results demonstrate that the total sum rate of the system can be improved. The findings reveal that the 4  ×  4 MIMO-VLC achieves a maximum sum-rate enhancement of 143% compared with the 2  ×  2 MIMO-VLC. The results also show that the efficiency of 4  ×  4 MIMO-VLC system with non-orthogonal multiple access (NOMA) and gain ratio power allocation (GRPA) was increased by around 181% compared to 2  ×  2 MIMO-NOMA-based VLC with GRPA in combination. For the 4  ×  4 MIMO-NOMA-VLC device with GRPA, the sum bit rate for two, three, and four users was increased by 40%, 33%, and 24%, respectively. Through this study, it can be concluded that GRPA scheme plays an important role in utilizing MIMO-VLC system sum rate of the MIMO-VLC system.


Recent advances in Wireless Sensor Networks (WSNs) have led to new paradigm for protocol design especially for sensor networks where energy awareness is an essential component. Most of the research, however, has been focused on to the development of routing protocols since they might differ depending on the application area and network architecture. Computational Intelligence (CI) based optimization techniques paved the way for energy efficient routing for WSNs. In this paper, we evaluated and analyse the performance of CI based routing protocols with classical LEACH protocol. Our simulation results shows that CI based routing protocol perform better in terms of energy consumption thus increasing network life over classical protocol.


In this paper we consider the well studied Thre-onine Synthesis pathway in E. Coli, leading from Aspartate to the end product Threonine, via a complex five step mechanism. Following linearization of each step in the pathway around pre-chosen physiologically sound set points, we assemble the (originally nonlinear) system as a linear uncertain polytopic one. We study the effect of the negative feedback-loops that are internally exerted on the system. We then probe the sensitivity of the system to variations in certain variables in order to asses the possible optimality of the system in the H2, H∞ and the L2 - L∞, L∞ - L∞ senses.


I examine a common market with the following institutions. Oligopolistic firms improve their productivity by R&D. Wages are determined by union-employer bargaining. Firms and workers lobby the authority that accepts new members and regulates unions' and firms' market power. The main findings are as follows. Small common markets have incentives to expand, but large ones are indifferent to new members. With product market deregulation, there is an upper limit for the size of the common market and the growth rate diminishes with integration.


A non‐hollowed‐out relativistic electron beam model is considered in which the axial current well exceeds the Alfven limit when the field‐configuration of the beam is highly force free. In this model, the current has an axial as well as an azimuthal component. For a given ratio of these two current components, a family of solutions is obtained in which there is an upper limit on beam radius. Over a large range of the beam radius, the axial current in our model is large compared with the current carried by a beam of the same radius in Hammer and Rostoker's model.


Objective:To control medical insurance expenditure, reform the payment and explore different estimation methods and insurance scheme under total prepayment.

According to main income diseases and main business diseases, how to perform the structure control in the process of total prepayment was discussed. Suggestion:Total prepayment and hospital collocation should be estimated scientifically and reasonably, reasonable structural control mechanism should be considered based on total prepayment.


Biomolecules (e.g. proteins and nucleic acids) as target analytes of microfluidic paper-based analytical devices (μPADs) are usually immobilized on a cellulose paper substrate (with intrinsically anionic surface) through physical adsorptions by van der Waals forces and electrostatic interaction thanks to cationic patches on the biomolecule. However, the physical adsorption could lead to weak biomolecule-substrate binding strength and thus low biosensing performance. Benefitting from the abundance of hydroxyl groups on the cellulose paper, chemical modification based on specific surface chemistries is capable of biofunctionalization on the μPADs by providing functional groups for covalent bindings with the target biomolecule. There are many previous reports on chemical modifications of cellulose surface for improvement of biomolecule immobilization. Nevertheless, no study has been performed on experimental evaluation of modification efficiencies of various biofunctionalization methods in the context of biosensing applications. In this paper, we compare five surface chemistries for protein immobilization on μPADs made from pure cellulose paper. For each chemical modification method, surface analyses were first conducted to monitor the surface modification process. Then, paper-based fluorometric experiments and colorimetric enzyme-linked immunosorbent assays (ELISA) were carried out on paper substrates modified by the five surface chemistries to compare their efficiencies of covalent protein immobilization. Finally, a stability experiment was carried out on the five types of surface-modified paper after 30 d storage. It was demonstrated that the potassium periodate (KIO4)-modified cellulose paper has the best performance with 53% increase in the signal output and 59% decrease in background noise of the colorimetric ELISA, and only 13% bioactivity loss after the 30 d storage. The comparison results provide a valuable experimental guideline for selecting the suitable surface chemistry for protein immobilization on μPADs.

Stamping belongs to one of the most important methods in metal forming industry. The production consumes much energy using conventional press machine. In order to save energy, a servo press of 6300 kN nominal force using FANUC servo system with permanent magnet electric machine was developed to replace a traditional hydraulic press of 8000 kN nominal force. The energy consumption during stamping production was measured and evaluated using different criteria. The results showed that the Energy per Stroke (EPS) and the Specific EPS of the developed servo press was 0.0945 kWh and 15.0e-6 kWh/kN, respectively, much lower than those of the replaced hydraulic press. The Energy Transfer Ratio (ETR) from the servo press input to the slide was 39.5%, at least 25% higher than the literature data. It is thus concluded that the method of using servo control technology can achieve remarkable energy saving effect in stamping industry.


ABSTRACT This study explored work–life imbalance and social support during the Spring 2020 COVID-19 shelter-in-place restrictions in the U.S. and their impact on perceived stress and depression. In addition, the study explored relationships among perceived social support from others, support-seeking behaviors, and the role of weak-tie support network preference and demographic variables in terms of perceived stress and depression. The findings indicate that when controlling for social support, work–life imbalance was a significant predictor of both perceived stress and depression during the shelter-in-place restrictions. Moreover, higher work–life imbalance was a significant predictor of higher weak-tie support preference, while lower perceived social support predicted higher weak-tie support network preference. In addition, the findings indicated significant differences in weak-tie support preference based on living arrangements as well as differences between gender and racial/ethnic groups in terms of perceived stress and depression. The implications of the study findings for theory and practice are discussed along with key limitations and directions for future research.


are adequately covered; however, the author misses the discussion behind the real and long-term goals (market domination and hegemonic role) of Western countries, their multinational companies, and their advertising agencies. To allow for a comparative analysis of BRIC countries, the author offers a template to explain the significance of the role of advertising agencies. For that reason, this book can serve as a great source of information and a useful guide for practitioners.


The study intended to investigate the evolution of the methodological conceptions of science and mathemathics teachers of basic school, occurred during the "Curso de Especializacao em Ensino de Ciencias e Matematica" at UNIVATESCentro Universitario of Lajeado-RS. This course was based on the theoretical proposals of the Grupo Didactica e Investigacion en la Escuela, of the University of Sevilla-Spain. The goal of this group is the formation of teachers as autonomous profesionals and investigators of their practice. The formation of these teachers occurs in a proccess in which the consideration of professional knowledge is a relevant content, besides other knowledges. In the evaluation of this curricular hipothesis, it was verified the existence of relatively complex initial conceptions, and a low percentual evolution toward the adopted reference didactic model.


Effects of sulfite on glucose and amino acid metabolism were examined with the following results: 1. The inhibitory effect on glucose oxidation of intact cells was not clearly observed with 1mM sulfite in the reaction medium, but TCA cycle metabolites such as malate, pyruvate and succinate showed a fairly good inhibition with the same concentration of sulfite. Sulfite showed a greater inhibition to glutamate and alanine oxidation of intact cells of Staphylococcus aureus than that of Escherichia coli and Proteus vurgaris. 2. By pre-incubation with sulfite, lactic, succinic dehydrogenase and L-amino acid oxidase in cell free extracts showed considerable low activity. Increased concentration of sulfite and prolongation of pre-incubation time resulted in enlargement of inhibitory activity. Aminotransferase of Escherichia coli was also inhibited with sulfite.


Retirement satisfaction was predicted from the emotional qualities of pre-retirement marital interaction in 49 male (M age = 63) and 31 female (M age = 61) retirees. In 1989, we measured physiological, behavioral, and subjective aspects of emotion while spouses discussed a conflict in their marriage. Five years later, we assessed retirement satisfaction for spouses who had retired in the intervening period. Husbands who were physiologically relaxed and affectively positive during marital interaction were happier in their subsequent retirements. Wives' retirement satisfaction was not predicted by the emotional qualities of marital interaction.


April Fool's Day is traditionally a day to play practical jokes on others, send people on fool's errands(差事),and fool the unsuspecting.No one knows how this holiday began but it was thought to have originated in France.


Investigations that were conducted with the help of overhead distribution line model reflected such situations as wire swinging cross, their contact with fallen trees and other earthed objects have shown that the overhead lines may operate rather long under such conditions. However leakage current may lead to dangerous high potentials on these objects and around them. The results of calculations and experimental research have revealed that in the rain leakage current on an earthed object and insulation resistance depends on the width of moistened zone and practically does not depend on an object size and shape. Leakage current does not exceed 3 mA at an operating voltage and 15mA at possible internal overvoltage and full insulation resistance is not less than 3…4 MW for actual overhead distribution line spans.


The aim of this article is to compensate the talk. In this article, I give an informal introduction to the Langlands correspondences and the Principle of Functoriality from the viewpoint of arithmetic geometry. I especially emphasized the role of `-adic Galois representations (instead of complex representations of the hypothetical Langlands dual group) in the theory of automorphic representations. This viewpoint is slightly different from the usual one. I would not be surprised if this article looks strange for 'automorphic' people. However, I still believe this viewpoint is very natural, useful and even necessary in some instances.

The sparse representation-based classifier (SRC) has been developed and shows great potential for pattern classification. This paper aims to gain a discriminative projection such that SRC achieves the optimum performance in the projected pattern space. We use the decision rule of SRC to steer the design of a dimensionality reduction method, which is coined the sparse representation classifier steered discriminative projection (SRC-DP). SRC-DP matches SRC optimally in theory. Experiments are done on the AR and extended Yale B face image databases, and results show the proposed method is more effective than other dimensionality reduction methods with respect to the sparse representation-based classifier.


This descriptive-qualitative research looked into the reasons why a seafarer is likened to a prostitute and in what aspects they are alike. It also aimed to determine from the key informants the practices and or procedures employed by shipping and manning companies in order to fill in the much needed position on board that has become a scarcity in the last years. Likewise it aimed to determine how these manning companies keep their present pool of officers in their roster. What are the strategies employed by the different manning companies in keeping their officers and crew loyal to their respective companies?


With its two main aquifers that feed five villages and serve about 60000 capita, Al-Gofra Oasis, middle Libya, has seldom been subjected thoroughly for water quality evaluation. This paper aims at addressing the current situation of the groundwater at the oasis, studies the sources of pollution to the aquifers and introduces a methodology based on multivariate statistics for better monitoring and regular evaluation of the water quality at that oasis. Multiple Regression Analysis was used to correlate the field water quality data with the laboratory measured chemical parameters. Groundwater is the main/only source of water in that region. The aquifer in Sokna and Wadan is confined and its rocks consist of sand, clay and sandstone. The quality of water in this aquifer is fairly good and the Total Dissolved Solids (TDS) range between 1200 to 1500 ppm. The aquifer in Hun is deep confined aquifer and the quality of water is poor, where the TDS ranges between 4000 and 5000 ppm.


The object of this study is the representation of the plot of the knight's novel "Iwein or the Knight with the Lion" in Western European art of the XIII-XIV centuries. The subject of the study is the features of the visual language of secular medieval art, which manifested themselves in various visual representations of this plot. The purpose of this work was to identify similarities and differences in the structure of various iconographic programs created on the basis of this novel in the period under review, to analyze the dependence of the visual interpretation of the text on the functional purpose of the monument (illuminated manuscripts and monumental murals), as well as to compare the existing visual representations of the history of Yvaine with the structure of the literary plot itself. The main research methods in this work are the methods of iconographic and iconological analysis, involving the identification of relationships between the images of the iconographic program of monuments and literary subjects on which these programs are based. The novelty of the work consists in identifying the structural features of the iconographic programs of the monuments under consideration, their similarities and differences from the programs of the religious content of the era under consideration, which is important for understanding the overall picture of the development of the visual language of Western medieval art of the XIII-XIV centuries. As a result of the conducted research, it is concluded that the considered secular programs are significantly inferior in their structural complexity to programs of a religious nature, most of them represent a visual interpretation of the plot intended to demonstrate and glorify the traditional lifestyle of the knightly estate and entertainment, and only one of the considered iconographic programs of this period has a complicated structure closest to the basic one It can be considered, as well as the text of the poems of Chretien de Troyes and Hartmann von Aue, in the context of understanding its religious basis.


Peach seedlings (Prunus persica L. Batsch cv. Ansbacher, Boyles, Clarke's Shanghai, Neilson (Fred Hill), Okinawa, O'Meara, Richens Nos 1,2 and 3, Tomm's Early and Tomm's Shanghai), which are commonly used as rootstocks for low chill peaches in coastal New South Wales, were all susceptible to Phytophthora cinnamomi and P. cambivora and to a lesser extent P. parasitica, P. citricola, P. cryptogea, and P. megasperma, when tested by stem inoculations in the glasshouse. Myrobalan H29C plum (P. cerasifera Ehrh.) cuttings showed more resistance than peach seedlings. Variety of seedling peach was highly significant in stem inoculation experiments, but the performance of each varied between experiments. Root inoculations in aerated nutrient solution showed all rootstocks were susceptible to P. cinnamomi, but Neilson (Fred Hill) peach was more tolerant than other seedling peaches and less tolerant than Myrobalan H29C plum. No recommendation could be made on a rootstock for low chill peaches more tolerant of root and collar rots and waterlogging.

Abstract : Four university professors, sponsored jointly by the Navy-ASEE Summer Faculty Research Program, the Naval Underwater Systems Center, and the Office of Naval Research, chose to visit NUSC during the summer of 1983 to participate in both the NUSC independent research project, Finite Difference Solutions to Acoustic Wave Propagation, and the ONR-sponsored research project, Computational Acoustics. Research was performed jointly by the authors of this document. This technical document reports significant technical progress attained during the visit. Time did not permit the authors to carry out the necessary computations during the summer; however, as a continuing joint effort, computational results will be produced later to verify the validity of the theoretical developments. Mathematical, physical, and computational contributions to the underwater acoustic wave propagations have been made due to combined multiple efforts among the authors presented here. These accomplishments not only enhance the PE capability by extending the solution to three-dimensional problems, but the work can be extended to handle acoustic wave propagations in elastic media. It is necessary that a complete numerical computation be performed to confirm the validity of these theoretical and computational developments. Keywords include: Finite difference; Hybrid parabolic equation; Parabolic equation; Range refraction; Sparse technique; Stability; Wide angle.


Figure 1. 3D micropattern force triggers YAP nuclear entry and modulates stem cells paracrine. In the triangular prism and cuboid micropatterns, the ordered F-actin fibers are distributed over the nucleus, which increased nuclear tension and stretched nuclear pores, thus enhancing the nuclear import of YAP. The activation of YAP enhances the paracrine of MSCs and upregulates the secretion of angiogenic growth factors. Scale bars, 20 μm. Adapted from ref. [ 7 ].


On the basis of one case of colonic sub-mucosal cystic pneumatosis explored by double contrast enema, the authors emphasise the pathognomic diagnostic value of the "puzzle" appearance. This appearance is made by precise adaptation of the opaque colonic mucosa depressed in the form of a "cupola" over the intraparietal gas bubble which results in the deformity. Endoscopy failed to reveal the disorder in the case reported here.


An organic solvent‐free two‐step column procedure is presented that provided robust, high yield and super clean separation of Li from silicate rock sample matrices. The measured δ7Li value for BHVO‐2 of +4.29 ± 0.23‰ (1s) is comparable with the reported values. The δ7Li values for GSJ JP‐1 (+3.14 ± 0.41‰, 1s) and USGS DTS‐2 (+4.91 ± 0.34‰, 1s) presented here provide new reference values for ultramafic rock reference materials.

The study findings show that majority of the organizations evaluate their training activities occasionally. The most widely used training evaluation tool is questionnaire. The widely accepted and used model of all organizations is Kirkpatrick model of training evaluation. The biggest challenge faced by organizations is time devotion of training evaluation and determining basis of training evaluation.


This paper shows the qualitative and quantitative results obtained on the test of cylindrical parabolic concentrators when the screens are designed using dot color changes to guarantee a better dot correspondence assignment and to make the optical test of the concentrator easier; the method allows to measure deformations from tenths of a millimeter to several millimeters, thus demonstrating that null screen method is good enough for testing surfaces with important deformations. On a second approximation, it is designed a null screen corresponding to the surface evaluated with the first one by fitting a fourth grade polynomial with crossed terms; with this, it is shown that the first test gets closer to the shape of the surface validating it.


We present a charge and self-energy self-consistent computational scheme for correlated systems based on the Korringa-Kohn-Rostoker (KKR) multiple scattering theory with the many-body effects described by the means of dynamical mean field theory (DMFT). The corresponding local multiorbital and energy dependent self-energy is included into the set of radial differential equations for the single-site wave functions. The KKR Green's function is written in terms of the multiple scattering path operator, the later one being evaluated using the single-site solution for the $t$-matrix that in turn is determined by the wave functions. An appealing feature of this approach is that it allows to consider local quantum and disorder fluctuations on the same footing. Within the coherent potential approximation (CPA) the correlated atoms are placed into a combined effective medium determined by the DMFT self-consistency condition. Results of corresponding calculations for pure Fe, Ni, and ${\mathrm{Fe}}_{x}{\mathrm{Ni}}_{1\ensuremath{-}x}$ alloys are presented.

Purpose – The initial purpose of this paper is to review the explanatory power that memetics promised for socio‐cultural evolutionary theory, for organisational adaptation, and emergent patterns of traits. Second, to argue that philosophical accusations and premature demands have retarded a science of memetics; regardless, isolated demonstrations of empirical research feasibility suggest a pragmatic resolution. Third, to speculate about practical applications, future advances, and prompt consideration about resuming methodological research initiatives that draw extensively from biology into organisational and managements science.Design/methodology/approach – Owing to present methodological immaturity of cultural science then a high conceptual level of meta‐methodology is required. This scope necessarily overlooks specific technical details. Life‐science principles are well known in comparison to the embryonic memetic and cultural sciences. The meme‐gene analogy builds a bridge across which we can draw can...
