The concept of immunization is currently one of the most widely discussed innovations in bond portfolio management. The interest in immunization, which allows one to nearly guarantee a minimum return performance over a specified investment horizon, is due in large measure to the desire on the part of bond managers to reduce the risk which has accompanied the recent swings in interest rates.


This book is an examination of neoclassical ballet initially in the French context before and after World War I (circa 1905–1944) with close attention to dancer and choreographer Serge Lifar. Since the critical discourses analyzed indulged in flights of poetic fancy a distinction is made between the Lifar-image (the dancer on stage and object of discussion by critics), the Lifar-discourse (the writings on Lifar as well as his own discourse), and the Lifar-person (the historical actor). This topic is further developed in the final chapter into a discussion of the so-called baroque dance both as a historical object and as a motif of contemporary experimentation as it emerged in the aftermath of World War II (circa 1947–1991) in France. Using Lifar as a through-line, the book explores the development of critical ideas of neoclassicism in relation to his work and his drift toward a fascist position that can be traced to the influence of Nietzsche on his critical reception. Lifar's collaborationism during the Occupation confirms this analysis. The discussion of neoclassicism begins in the final years of the nineteenth-century and carries us through the Occupation; then track the baroque in its gradual development from the early 1950s through the end of the 1980s and early 1990s.


A large number of various empirical correlation and theoretical models have been suggested to describe the dependence between soil loss and basic erosion factors. No one of them, however, can explain the entire spectrum of numerous (and at times contradictory) experimental and field data A hydrophysical concept of soil erosion and sediment transport suggested by the authors is based on three postulates. The corollaries from these postulates can explain the whole diversity of data obtained earlier. The correctness of the postulates is also confirmed by specially designed experiments. The suggested concept can be used for physical validation of the models of erosion and sediment transport by hillslope water flows.


Aims: The aim of the study was to investigate the relationship between fitness indicators and cognitive performance with the parameters of the sleep study (PSG) in patients with obstructive sleep apnea syndrome (OSAS). Materials and methods: 47 OSAS patients (Age: 46.7±10.3 yrs, BMI: 32.9±7.2 kg/m2, AHI: 46.7±26 /h, Male: 74%) comorbidity-free included in our study. The somatometric characteristics were collected, a subjective evaluation of exercise intensity according to the Borg scales, as well as a cognitive assessment (MoCA test), were recorded, while patients underwent 6-minute walk test (6MWT). Exclusion criteria: age l20 and g60 yrs, BMI ≥40 kg/m2, WHR g1, neck circumference ≥40 cm and physical activity l100 min/week. Results: From PSG measurements, AHI was negatively correlated with 6MWT (pl0.01) and the cognitive domain of Orientation (pl0.05), and minimum SpO2 with the domains of Attention/Working Memory and Orientation (pl0.05). Perceived leg fatigue (fL) according to Borg scale was negatively associated with Attention/Working Memory (pl0.05), whereas HRrest positively with fL (pl0.05). Differences were recorded in Borg scale for fL (cut-off point 2 score) compared to the parameters of MoCA score (pl0.01) and of Borg scale for perceived dyspnea (pl0.01). 6MWT demonstrated differences with fL with cut-off point 400 m (pl0.05). Conclusion: The overestimation of the perceived sense of the intensity of the exercise, in combination with the reduced physical condition, is associated with cognitive decline, particularly with distinctive domains, in the framework of apneic episodes in OSAS patients.


Objective: To investigate the clinical value of two-dimensional and three-dimensional ultrasound in prenatal diagnosis of hemivertebrae. Methods: To analyze two-dimensional and three-dimensional ultrasonography imaging features in hemivertebrae. Results: Two-dimensional ultrasound has many characteristics of hemivertebrae. Three-dimensional ultrasound can be used to visualize the degree of scoliosis. Accurate positioning of the vertebrae, is important for performing two-dimensional ultrasound technique. Among the 12 fetuses, 5 fetuses had single vertebral deformity, 7 fetuses had multiple vertebral deformities, 6 cases occurred in the thoracic spine, 3 cases in the lumbar spine, 1 case in the sacral segment, 1 case in the cervical and thoracic, 1 case in the thoracic and lumbar. Besides the vertebral defect, 8 fetuses had additional anomalies, of which 4 fetuses had cardiac malformations, 2 fetuses had urinary tract abnormalities, 2 fetuses had abnormal limb development, 2 fetuses had central nervous system malformations, 2 fetuses had oligohydramnios. Conclusion: We found that hemivertebrae has typical ultrasonic features, ultrasound had significant clinical value.


METHODS: Ten female division III long jumpers (19.20 yrs ± 0.92, 165.0 cm ± 7.1, 58.1 kg ± 3.4) completed four conditions (Control 1, Treatment 1 (LDT) Treatment 2 (HDT), and Control 2) consisting of three jumps each. LDT was a target on the ground at the end of the sand pit, HDT was a target high in the air at the end of the pit, and the control conditions were the jumper's normal focus. Each athlete completed an attention focus questionnaire at the end of each condition. Photocell timing gates were positioned to collect approach speed. A high speed video camera (200 hz) recording a sagittal view of the take-off was used to determine horizontal velocity at take-off, vertical velocity at take-off, and take-off angle. Jump distance was measured using standard NCAA procedures using markings in the sand. A 4 x 3 condition by trial repeated measures ANOVA was completed for all jump performance data. RESULTS: Focusing on a HDT did not lead to significantly further jumps (4.58 m ± 0.27) compared to focusing on a LDT (4.58 ± 0.30) or Control 1 (4.64 m ± 0.20). Athletes jumped the furthest in Control 2 (4.74 m ± 0.30). No significant differences were found in take-off angle (Control 1 21.28 ° ± 7.04, LDT 19.20 ° ± 4.45, HDT 18.35 ° ± 6.23, Control 2 18.38 ° ± 4.32). Athletes commonly reported looking up while jumping in the control conditions (Frequency: Control 1 = 21, Control 2 = 23). CONCLUSION: Changing an athlete's focus of attention is not an effective strategy to improve long jump performance. Athletes performed best when using a self-selected focus of attention, which based on self-reports generally involved looking up while jumping. Future studies may consider training athletes to use a specific focus of attention prior to testing.

Aspects of the geometric discretization of electromagnetic fields are considered. The convenience of the use of differential forms to represent the field quantities through natural role as duals (cochains) of the geometric constituents of the lattice (nodes, edges, faces, volumes) is reviewed. The use of a (primary) simplicial lattice, and a barycenter subdivision to decompose the associated (barycentric) dual lattice into simplicial elements are treated briefly. Using this subdivision, lattice Hodge operators are built by defining Whitney maps on the barycentric subdivision.


A pothole is one among the first reasons for road accidents and is becoming increasingly important to detect while driving on roads. Detection and warning can significantly reduce accidents and damages caused to vehicles. Advanced neural networks process the pictures from the camera on a realtime basis to spot if there is a pothole within the image. Detection of potholes using neural networks will be time-consuming. Recently, the advances in artificial neural network have led to varied high-performance single-shot detection algorithms. These algorithms are especially useful in real-time applications. Hence, in this paper, we present a study of various object detection algorithms towards pothole detection with its speed and accuracy. The dataset comprises around 9000 training images with and without potholes. The article analyzes Yolo V3, Yolo V4, Yolo V5, and SSD algorithms to judge the results with the identical dataset for training and evaluation.


Over-exploitation on natural live rock promotes the degradation of ocean ecosystem. This concern has been raised since harvesting may reduce the density of marine ornamentals and degrade marine habitat quality. This study aims to develop artificial live rocks (ALR) that potentially to be used as one of the alternatives to reduce the overharvesting activity toward natural live rocks. The study was conducted at Bidong Island, Terengganu started from April to October 2014. There were 2 types of ALR used in this study; rough and smooth surfaces. A total of 64 pieces of ALR were deployed in April 2014 and retrieved in June, August and October 2014 respectively. Identification in terms of coral spat species and macrobenthic organisms was done after the each retrieval. Coral spat was identified based on the morphology of their columella, septa and corallite wall by using Dinolight Digital Camera. Four species of coral juveniles (Pocillopora damicornis, Stylophora pistillata, Seriatopora hystrix and Acropora millepora) were found attached on ALR surfaces. Whereby, there were 11 phyla of epibenthic organisms were found to attach on ALR which dominated by turf algae and red algae. Percentage coverage of epibenthic calculated using Coral Point Count with Excel extension (CPCe) shown ALR was dominated by turf algae after 2 months (69%) and 4 months (20%) of deployment respectively. Afterward, Red algae (31%) dominated after 6 months of deployment. There was significant difference between coral species and the surfaces (p 0.05). This finding showed that ALR has a potential to be upgraded as artificial reef towards marine habitat restoration.

From the view of water cycling,runoff coefficients are important index of water resources in a particular catchment.Changes of runoff coefficents in the five rivers of Lake Poyang basin 1955-2002 were analysed.Result shows that runoff coefficients of Raohe River basin and Xinjiang River basin are the highest,while of Fuhe River basin is the lowest.As for monthly change,that of the five river basins all have reached the higher value from April to June,which corresponds to the rainfall period of Poyang Lake basin.Moreover,In August,runoff coefficient of Fuhe River basin is far lower than the four others.In the 1990s,runoff coefficients of the five river basins increased significantly.Although the runoff coefficients would be impacted by soil erosion and topographic condition,change of precipitation is a main factor to runoff coefficients.Downward trend of evapotranspiration also impacts on increas- ing runoff coefficients.Especially in the 1990s,the increase of runoff coefficients is closely related to the increase in rainstorm frequency and decrease in evapotranspiration.The relationship between temperature and runoff coeffi- cients is not much significant.

The mechanisms of traumatic injury-induced acute kidney injury (AKI) are very complicated. Among these mechanisms, sepsis-related AKI is the most harmful and the most difficult to treat. The medical community gave a high priority on this disease, dedicated to raise the level of awareness and treatment through its pathogenesis, early diagnosis ideas and biomarkers, and standardization of treatment. There has been some consensus on the classification of sepsis, AKI, and treatments of antiinfection, fluid resuscitation, renal replacement therapy. A series articles and guidelines have also been published and the survival status of patients have been improved, but many basic and clinical issues are still controversial and need to be answered by further trails. This article focuses on the progress of pathogenesis, diagnosis and treatment about sepsis-related AKI, and tries to raise the understanding level of early diagnosis and standardized treatment of it.

Leishmania parasites seem capable of producing cysteine by de novo biosynthesis, similarly to bacteria, some pathogenic protists, and plants. In Leishmania spp., cysteine synthase (CS) and cystathionine β‐synthase (CBS) are expected to participate in this metabolic process. Moreover, the reverse transsulfuration pathway (RTP) is also predicted to be operative in this trypanosomatid because CBS also catalyzes the condensation of serine with homocysteine, and a gene encoding a putative cystathionine γ‐lyase (CGL) is present in all the sequenced genomes. Our results show that indeed, Leishmania major CGL is able to rescue the wild‐type phenotype of a Saccharomyces cerevisiae CGL‐null mutant and is susceptible to inhibition by an irreversible CGL inhibitor, DL‐propargylglycine (PAG). In Leishmania promastigotes, CGL and CS are cytosolic enzymes. The coexistence of de novo synthesis with the RTP is extremely rare in most living organisms; however, despite this potentially high redundancy in cysteine production, PAG arrests the proliferation of L. major promastigotes with an IC50 of approximately 65 μM. These findings raise new questions regarding the biological role of CGL in these pathogens and indicate the need for understanding the molecular mechanism of PAG action in vivo to identify the potential targets affected by this drug.


Every L-shaped house is the same in Lavender Lakes (which is neither lavender nor near a lake). Each one is conveniently divided into two notquite-identical duplexes. On Wednesday mornings, the trash cans uniformly appear on the curbside. They uniformly disappear Wednesday night. The pointing of the bricks is perfect; in fact, the only blemish is the dark stain on the white driveway of 216 that appeared the night I moved in and parked my beat-up truck there. My pickup is the only vehicle in the neighborhood more than five years old. Here, the cars and the houses are the same age. Nothing grows old. The neighborhood is twenty minutes from town, conveniently located off Tallassee Road, which connects to Jefferson Highway and the Loop. The development was cut out of cheap, unused pine and scrub. Around each house, the trees have been neatly leveled and replaced with hydroseed. Twenty yards from my back door, the woods resume. At night, they buzz and chirp and howl.

Non-Ideal Compressible Fluid-Dynamics (NICFD) has recently been established as a sector of fluid mechanics dealing with the flows of dense vapors, supercritical fluids, and two-phase fluids, whose properties significantly depart from those of the ideal gas. The flow through an Organic Rankine Cycle (ORC) turbine is an exemplary application, as stators often operate in the supersonic and transonic regime, and are affected by NICFD effects. Other applications are turbomachinery using supercritical CO2 as working fluid or other fluids typical of the oil and gas industry, and components of air conditioning and refrigeration systems. Due to the comparably lower level of experience in the design of this fluid machinery, and the lack of experimental information on NICFD flows, the design of the main components of these processes (i.e., turbomachinery and nozzles) may benefit from adjoint-based automated fluid-dynamic shape optimization. Hence, this work is related to the development and testing of a fully-turbulent adjoint method capable of treating NICFD flows. The method was implemented within the SU2 open-source software infrastructure. The adjoint solver was obtained by linearizing the discretized flow equations and the fluid thermodynamic models by means of advanced Automatic Differentiation (AD) techniques. The new adjoint solver was tested on exemplary turbomachinery cases. Results demonstrate the method effectiveness in improving simulated fluid-dynamic performance, and underline the importance of accurately modeling non-ideal thermodynamic and viscous effects when optimizing internal flows influenced by NICFD phenomena.

Effect of immune stimulation and stocking density on growth, immunocompetent organ weight and plasma alpha 1 acid glycoprotein (AGP) concentration was studied in male broiler chicks to develop a laboratory model for studying a chronic immunological stress. Sephadex (G-50, 250mg/ kg BW) and/or Escherichia coli lipopolysaccharide (LPS, serotype 0127: B8 500μg/kg BW) were used as agents to stimulate the immune system. Chicks were reared in two different stocking densities (217 and 650cm2 per chick) in experiment 1, and kept at 650cm2 per chick in experiment 2. In experiment 1, injection of Sephadex alone every other day over 10 days tended to reduce body weigh gain as compared to a saline injected control, but the effect was not significant. Injections with Sephadex and LPS on alternate days over 10 days significantly reduced body weight gain in chicks kept at 650cm2 per chick. In experiment 2, injections of LPS and Sephadex on alternative day over 5 days significantly reduced body weight gain and feed consumption. Relative spleen weights were higher in the chicks treated with LPS and Sephadex than those in the control chicks in both experiments. Alternate injections of LPS and Sephadex, or Sephadex injection alone increased AGP concentration in plasma in both experiments. The results suggested that injection with Sephadex and LPS on alternate days over 5 days mimics responses to a chronic stress such as reduction in growth and feed utilization, enlargement of liver and spleen, and activation of certain inflammatory responses. This laboratory model could be a useful way for finding novel nutrient(s) to alleviate the decreased rates of body weight gain and feed consumption by immunological stress.

We consider the multi-server queueing system with an infinite retry orbit and a finite priority group. Arriving priority customers find that all the positions of priority group are occupied and join the orbit; these customers become the ordinary customers. Arriving ordinary customers find all servers busy and join the orbit directly. The model is quite general enough to cover most of the systems in communication networks. The arrival rates and service rates of ordinary customers and priority customers are different in our research. We derive the steady state condition and the main performance indexes of the system. The effects of various parameters on the system performance measures are illustrated numerically.


This paper challenges narrow conceptions of the '60's women's movement that render invisible the activism of women of color. I describe an influential '60's group of black and mainly poor women, the Mt. Vernon/New Rochelle group, who were militant women's liberationists. The research is based on primary written sources and interview with core members. I compare the group's political approach with white and middle-class approaches in this period. of ethnic identification, its to community involvement and the ways it intersects with gender, race and class through an analysis of in depth interviews with eighteen Armenian American women. Current constructions of ethnicity are challenged by the following what are the tensions specific to ethnic women; what is the relationship for women between community involvement and ethnic identification; is the assimilation process ever complete; what are the ways in which ethnicity is manifest in individual lives and consciousness; and finally, what is the role of race and class in defining and maintaining ethnic identification for women? the perceived realities of middle class African they middle the for the development of an organic African American theory of life in contem American to some popular and these and discrimination still as a negative force in the life chances of African Americans-even when class as a variable drawing explores the ways in which identity politiCS as a political strategy can act to sideline the political issues of women of fragment and divide them by forcing them to act within simplistic notions of identity and ethnicity. Read together, inspire a multifaceted look at gender, identity, and the potential for cross-cultural political alliances, an interrogation of the very act of writing, theorizing and acting on and about these of issues. the in based Panel Abstract: As academia moves toward a system that is becoming more involved in "cultural studies" it becomes more important for scholars of all fields to acknowl edge how race and gender issues affect and shape our disciplines. In the area of literature we have begun to explore the way that these issues affect all writings, and especially that of black and white women. By starting with an examination of how these issues impacted the nineteenth-century writings of Harriett B. Stowe, the Harlem Renaissance writings of lora Neale Hurston and moving to the contemporary writings of Alice Walker and Toni Morrison, this panel attempts to identify examples of miseducation, dehumanization, and isolation. After identifying these methods of oppression, the panelists subsequently move towards various methods of overcoming their various modes of oppression through (re)education, reification, and reclamation. and Haunting: Toni Morrison's and (Re)Claiming the Self." This paper will the movement towards personal wholeness of Morrison's Panel Abstract: Through the words of Chicana writers, a sense of community, based on identity and lived experience, emerges. Both reactive and proactive in nature, the works of Chicana writers represent activism in which life is theory, and reality is political as Chicanas partially rise out ofthe silence of marginalization through the act of writing. But what do these voices, these words mean, both in and out of context? What of audience? Who listens? Who reads? What does it mean when Chicana writing is labeled as threatening to Chicano community? What is at issue when community-based writing is evaluated in a non-community venue? What risks accompany academic interpretation, especially that of non-Chicana persons? Our panel seeks to explore these and other questions relevant to Chicana community, by presenting and representing Chicana voices in conversation. Issues of marginalization within marginalization, objective subjectivity, and relevance of literary form to meaning will be examined in the context of Gadamerian hermeneutics. The panel wishes to explore the paradoxical reality that exists when objectified subjects, forced to acknowledge their objectification, maintain the integrity of their autonomous selves. Additionally, the panel will serve as an instrument by which meta-critical Panel Abstract: Each of these three papers describes popular culture, in varied forms, as contributing to racist thinking. Brooks's paper is a discussion of racism in a contemporary novel by Pauline Hopkins. Douglas's paper is a discussion of racism embedded in differing popular cultural forms, including the minstrel show, popular art, television and films. While, Manning-Miller argues that the media presents a skewed and racially biased view of the poor and the welfare mother. All of these papers suggest that we have not come very far in our poplar cultural conceptions of people of color. These papers present a critique of our popular cultural styles as they contribute to racist thinking. and the possible impact of coverage of on and the of white that the of


The papers in this special issue mark an important stage in the now vibrant development of scholarship relating to alternative food initiatives and movements around the world. These papers particularly represent the recent developments of such movements and their scholarship in Canada. What is impressive about this Canadian scholarship are both its empirical rigour and scope, as well as its recourse to theoretical and conceptual advancement. The scholarship reflects detailed and extensive empirical work and the co-production of knowledge with over 170 community-based food initiatives in Canada (Blay-Palmer et al. 2013). As such, it begins to overcome, possibly for the first time, the over-reliance on individual case study research that has somewhat dominated the field thus far. Whilst this is understandable, in these papers, we begin to see the larger alternative and highly variegated agri-food landscape, given the scale of empirical and comparative research. In doing so, more improved definitions of alternative food hubs – as examples of place-based hybridity – come to the fore. More importantly still, we see methodological attempts (like in the Mount and Andrée paper) to map this place-based terrain in new ways. These are important developments for alternative agri-food scholarship; we would like here to help to build on these achievements by focusing upon some of the theoretical and conceptual implications of the work, and on the current state of the alternative agri-food literature more generally. The more I read and reflected on these papers, and reflecting on my recent attendance and participation in both the vibrant Canadian and Australasian agri-food conferences in 2012, I began to see a way through what we might regard as something of a theoretical impasse (indeed a conceptual "trap") emerging in the field. So here, we want to use this limited space and contribution to outline some theoretical implications that might allow further progress in this regard. Clearly what we suggest here is also something of an Atlanticist perspective, being based here in Europe, and indeed more specifically in the UK, whilst also participating first hand in the Canadian research, thanks to the intellectual energies of many of the authors. In developing these arguments, we are also drawing on recent significant attempts, on both sides of the Atlantic, of synthesising the latest research and scholarship in this developing field. Two recent volumes are highly relevant in this regard; the monograph by Goodman et al. (2011), where they ambitiously compare the North American and European experiences; and the collection led by Spaargaren et al. (2012), which provides an excellent landmark study of agri-food, largely from a European perspective in what they frame as the "age of reflexive modernity".


Aim of Study: To assess the role that can be played by MRI to minimize the number of false positive cases of breast tumors that commonly occur with mammography. Patients and Methods: This study included 200 consecutive patients aged 40 years or more, who were referred to the Department of Radiology for suspicion of a breast lump. Mammography then magnetic resonance imaging (MRI) was performed for each patient. A patient with a positive finding in any of these two modalities underwent histopathological diagnosis. Sensitivity and specificity were calculated for each imaging modality and that for MRI of mammography positive patients. Results: Most common benign lesion were fibroadenoma (11%) and radial scars (5.9%), while the most common malignant tumors were invasive ductal carcinoma (37.3%) and ductal carcinoma in situ (21.2%). Prevalence of breast tumors among participants increased with their age. Prevalence of breast tumors among nulliparous participants was significantly higher than that among parous participants (88.6% Vs. 72.5%, respectively, p=0.01). The prevalence of breast tumors was significantly higher among those with positive family history of breast cancer (93.2%) than those with negative family history (70.6%), p=0.003. Mammography provided a higher sensitivity than that provided by MRI (97.5% Vs. 90.7%, respectively), but a lower specificity (48.6% Vs. 94.3%, respectively), which has been fully improved by the application of MRI on cases who were positive by mammography (100%). Conclusion: The application of MRI for cases with positive mammographic findings can be a cost-effective procedure that greatly limits false positives, increases specificity and spares unnecessary invasive interventions. Recommendation: To conduct a community-based study to assess the role and cost-effectiveness of MRI in screening for breast cancer among females aged over 40 years, applying MRI on all those with mammographic findings.


Direct dark matter detection experiments will soon be sensitive to neutrinos from astrophysical sources, including the Sun, the atmosphere, and supernovae, which will set an important benchmark and open a new window into neutrino physics and astrophysics. The detection of these neutrinos will be complementary to accelerator- and reactor-based experiments that study neutrinos over the same energy range. We review the physics and astrophysics that can be extracted from the detection of these neutrinos, highlighting the potential of identifying New Physics in the form of light mediators that arise from kinetic mixing and hidden sectors, as well as ∼eV-scale sterile neutrinos. We discuss how the physics reach of these experiments will complement searches for New Physics at the LHC and dedicated neutrino experiments.


In patients with lifestyle-related diseases such as hyperlipidemia,medication adherence tends to be low due to lack of subjective symptoms.The purpose of this study was to evaluate the usefulness of a visual aid in medication guidance given to patients on statins at a community pharmacy.As the visual aid,we used the J-LIT(Japan Lipid Intervention Trial)chart,a diagram based on the results of J-LIT which helps patients visualize the risk of developing a coronary heart disease.We first developed software(J-LIT chart plotter)to enable the J-LIT chart to be displayed on a computer and then added details of the importance of treatment with statins to the chart.The effectiveness of this new way of providing information to patients was investigated using a questionnaire whose responses indicated that most patients had a better understanding of treatment with statins.This should improve adherence in statin therapy.The patients seemed satisfied with the new way of providing guidance and most of them wanted it to be continued.In conclusion,in a community pharmacy,guidance on drug administration in which patients can understand the significance of clinical laboratory values and risk of developing coronary heart diseases visually seems to be an effective way of improving medication adherence in the case of those who have chronic diseases that require long-term treatment but show few subjective symptoms.

The pre-alloyed Fe-1.1Ni-0.5Mo-0.5Cr powder was prepared by inactive gas atomization.The mixtures were prepared with 0.5% wax as lubricant and 0.6% graphite,1.5% copper(all in mass fraction) as additives.Then the pre-alloyed powder was homogeneously mixed with the mixture and respectively adding 0%,10%,20% and 30% reductive iron powder,and followed by pressing at 600 MPa and sintering in H2 atmosphere at 1 180 ℃ for 1 hour.Finally the sintered alloys were tempered at 180 ℃ for 1 hour.The density,hardness and tensile properties of the tempered alloys were detected.Their microstructure and fractography morphology were analyzed.The results show that the density and tensile strength of the sintered alloys increase greatly while their hardness keep at high values;the alloys have good sinter hardening property,martensite is the basic microstructure of sintered alloys,meanwhile pearlite,lower bainite and even upper bainite are appeared in their microstructure with the increasing of reduced iron powder;the sintered alloy added with 20% reduced iron powder has the best synthesis performance,such as the hardness and tensile strength reach 42 HRC and 635 MPa respectively at density 6.84 g/cm3.The above results indicate that the powder forming property and mechanical property could be improved by the addition of reduced pure iron powder.


III HIV-1 integrase is an essential enzyme in the HIV replication cycle and is a validated target for antiretroviral drugs. Due to the inevitable emergence of drug resistance of HIV-1 strains to all currently approved FDA antiretroviral drugs, antivirals with new mechanisms of action are continuously investigated. As such, this study aimed to reposition existing drugs as HIV-1 integrase inhibitors by screening the NIH Clinical Collection compound library comprising 727 compounds. Recombinant integrase was expressed in bacterial cells, purified by nickel affinity chromatography, and used to set up a Scintillation Proximity Assay (SPA). The SPA was subsequently amended to an automated system to allow for rapid screening of compounds. The complete compound library was successfully screened using the newly established automated SPA. Overall, only two compounds were identified as HIV-1 IN inhibitors: cefixime trihydrate and a previously identified HIV integrase inhibitor, epigallocatechin gallate. These compounds exerted IC50 values < 10μM in the automated SPA. Cefixime trihydrate was not toxic to mammalian cells (CC50 > 200μM) while no appreciable antiretroviral activity was observed in in vitro phenotypic inhibition assays (23% inhibition of viral replication), thus concluding that this compound was nonselective. By contrast, epigallocatechin gallate was toxic to mammalian cells at the evaluated ranges (CC50 = 23 + 1μM) and therefore could not be validated as an integrase inhibitor in in vitro phenotypic inhibition assays. Overall, this study resulted in the establishment of an automated SPA, the successful screening of 727 compounds, and the availability of a platform to expedite the future screening of potential HIV-1 integrase inhibitors.

The use of both 4-bromoisophthalic acid (H2Brip)/5-nitroisophthalic acid (H2nip) and 4,4′-dipyridyldisulfide (dpds) with Co(II) ion under hydrothermal conditions has provided two new Co(II) coordination polymers, [Co(dps)(Brip)]n (1) and [Co(H2O)(dpds)(nip)]n (2), respectively. The two compounds have been characterized by elemental analysis, FT-IR spectroscopy, and X-ray single-crystal diffraction. The starting reagent dpds ligand was converted to dps (4,4′-dipyridylsulfide) in 1. For complex 1, it crystallized in monoclinic system, P21/c space group. Two Co ions are linked by carboxylate oxygen atoms to form a 4-membered [Co2O2] ring. The rings are linked by Brip to generate a 1D polymeric motif. These 1D motifs are further connected through dps to generate a 2D network. For complex 2, it crystallized in orthorhombic system, Pbcn space group. The adjacent Co(II) ions are bridged by Brip to form an alternate 1D chain. Such 1D chains are further connected by dpds to generate a 3D twofold interpenetrating diamondoid network.


The growth hormone receptor knockout (GHRKO) mice are remarkably long‐lived and highly insulin sensitive. Alterations in mitochondrial biogenesis are associated with aging and various metabolic derangements. We have previously demonstrated increased gene expression of key regulators of mitochondriogenesis in kidneys, hearts and skeletal muscles of GHRKO mice. The aim of the present study was to quantify the protein levels of the following regulators of mitochondriogenesis: peroxisome proliferator‐activated receptor γ co‐activator 1α (PGC‐1α), AMP‐activated protein kinase α (AMPKα), phospho‐AMPKα (p‐AMPKα), sirtuin‐3 (SIRT‐3), endothelial nitric oxide synthase (eNOS), phospho‐eNOS (p‐eNOS), nuclear respiratory factor‐1 (NRF‐1) and mitofusin‐2 (MFN‐2) in skeletal muscles and kidneys of GHRKOs in comparison to normal mice. We also were interested in the effects of calorie restriction (CR) and visceral fat removal (VFR) on these parameters. Both CR and VFR improve insulin sensitivity and can extend life span. Results: The renal levels of PGC‐1α, AMPKα, p‐AMPKα, SIRT‐3, eNOS, p‐eNOS and MFN‐2 were increased in GHRKOs. In the GHRKO skeletal muscles, only MFN‐2 was increased. Levels of the examined proteins were not affected by CR (except for PGC‐1α and p‐eNOS in skeletal muscles) or VFR. Conclusion: GHRKO mice have increased renal protein levels of key regulators of mitochondriogenesis, and this may contribute to increased longevity of these knockouts.

Abstract Felix Bonfils was born in Saint Hippolyte du Fort, France, on 6th March 1831. Little is known of his early life. Family sources indicate he began his professional career by operating his own printing press1. On becoming interested in photography, he produced photographs using the heliogravure process invented by Niepce. In due course, he adopted the collodion wet-plate process, with all its well-known complications and encumbrances. For the landscape photographer lie was to become, the task of moving his equipment from place to place must have been formidable, especially in countries where roads and transport were meagre.


We propose an ultrasmall and wideband polarization rotator consisting of a short silicon wire and an off-axis silicon oxinitride waveguide. The simulated extinction ratio is found to be over 20 dB for the C-band.


In optical techniques, noise signal is a classical problem in medical image processing. Recently, there has been considerable interest in using the wavelet transform with Bayesian estimation as a powerful tool for recovering image from noisy data. In wavelet domain, if Bayesian estimator is used for denoising problem, the solution requires a prior knowledge about the distribution of wavelet coefficients. Indeed, wavelet coefficients might be better modeled by super Gaussian density. The super Gaussian density can be generated by Gaussian scale mixture (GSM). So, we present new minimum mean square error (MMSE) estimator for spherically-contoured GSM with Maxwell distribution in additive white Gaussian noise (AWGN). We compare our proposed method to current state-of-the-art method applied on standard test image and we quantify achieved performance improvement.

Chapter 6 explores the dramatic events spurring Melania and her entourage to leave Rome in advance of the Gothic sack of the city in August 410. After the death of Melania's father in perhaps 405 or 406, Melania and Pinian went to a suburban property to begin their renunciations. Goths advanced into Italy starting in 401; from 407 onward, Alaric demanded ransom money and goods to prevent his attack on the city. Serena, wife of Stilicho and a member of the imperial court, had arranged with the emperor for court officials to assist the couple with the divestment of their property. When both Stilicho and Serena were killed, Melania and Pinian lost a major source of protection. The emperor Honorius dawdled in meeting Alaric's requests, and Roman senators resisted parting with their wealth to pay the ransom. The Roman city prefect perhaps attempted to confiscate the couple's property in order to pay the ransom but was killed in a riot over the bread supply. The extreme difficulty of divesting themselves of their possessions is clearly on display (Serena herself had claimed that she could not afford to buy their Roman mansion), as is the fierce opposition of their relatives, especially Pinian's brother. The sack of Rome elicited various responses from Christian and pagan writers.


General two Higgs doublet models allow for five scalar bosons, three of which being neutral. No signal is found in the data collected by the L3 detector in e+e- collisions at 189 – 202 GeV center-of-mass energies. Limits are set on the couplings of the h and A Higgs bosons to the Z boson.


Probably the first questions that arise when one starts to depict Turkish foreign policy (TFP) towards the Balkans are 'what does Turkey really do in the region and what does it really want to achieve?' which practically means that research may focus on the tools and the object of Ankara's external ambitions. Nevertheless, for the author, to reveal the cause seemed to be more relevant because it may provide a deeper understanding of Turkish foreign policy's nature, motives and makes its prediction easier.


10.21276/sajb.2018.6.1.10 Abstract: The main aim of this study was to see the primary and secondary phytochemicals of the common water hyacinth, Eichhornia crassipes and the marine brown alga, Sargassum cristaefolium, and evaluation of their effects on the growth of the freshwater prawn, Macrobrachium rosenbergii post-larvae (PL). The phytochemical properties of E. crassipes and S. cristaefolium were analyzed using petroleum etheric (non-polar solvent) and ethanolic (polar solvent) extracts. Presence of primary phytochemical components, such as alkaloids, terpenoids, flavonoids, tannins, polyphenols, saponins, cardiac glycoside and quinines, and significant amounts of total phenolic and total antioxidant contents were recorded in E. crassipes, and S. cristaefolium. E. crassipes showed the presence of totally 14 secondary metabolic components, of which 5 from petroleum etheric extract and 9 from ethanolic extract. Among these 3 compounds, Dodecanoic acid; 6,7-Dimethoxy-2-tetralone; and, 3,7,11,15-Tetramethyl-2-hexadecen-1-ol, and 5 compounds, Phenol, 2-methoxy-5-(1propenyl)-, (E); Cycloheptane, 1,3,5-tris(methylene); 4-(6,6-Dimethyl-2methylenecyclohex-3-enylidene) pentan-2-ol; Tetradecanoic acid; and, Loliolide of the respective solvent extracts possessed bioactive properties. In S. cristaefolium, totally 13 secondary metabolic components were detected, of which 6 from petroleum etheric extract and 7 from methanolic extract. Among these, one compound in each extract, Docosane, and cis-2-[2-(hydroxymethyl)cyclopentyl] ethanol, respectively possessed bioactive properties. The basal diet was prepared using fish meal, groundnut oilcake, soy bean meal, wheat bran, sunflower oil tapioca flour, egg albumin and vitamin-B complex with vitamin-C and used as control diet. The fishmeal was replaced with raw powder of E. crassipes, and S. cristaefolium, independently at 5, 10 and 15%. Similarly, each solvent extract of E. crassipes, and S. cristaefolium, was independently incorporated with the basal diet at 0.5, 1.0, and 1.5%. These diets were fed to M. rosenbergii PL for 60 days. Significant improvements in survival rate, weight gain, food conversion ratio, content of total protein and ash were recorded in experimental PL when compared with control. This was found to be the best at 10% incorporation of raw powder of each weed, and 1.5% ethanolic extract, as well as pertroleum etheric extract of each weed. Among these two weeds, E. crassipes produced a little better performance than that of S. cristaefolium. Among the two solvents, ethanolic extract produced better result than that of petroleum etheric extract. This may be due to presence of more number of bioactive components in ethanolic extract, or due to the presence of a particular bioactive component. Therefore, the raw powders of E. crassipes and S. cristaefolium are recommended as ingredients, and their ethanolic extracts are recommended as feed additives in aqua feed formulations for sustainable culture of M. rosenbergii.


Since the inhibition function of anti-oxidant pyrrolidine dithiocarbamate(PDTC) to nuclear factor kappa B(NF-κB) was reported,function and mechanism of PDTC in some disease had become the research hot point.Abundant experimental evidence showed that PDTC was able to inhibit NF-κB activation,and had the therapeutic effects on the disease associated with NF-κB.But,there was scarcely research concerning on PDTC in asthma.Consequently,the relationship between anti-oxidant PDTC and the important factor NF-κB in asthma are reviewed,in order to provide a reference for the treatment of asthma.

Access to adequate sanitation facilities is a basic human right and fundamental to good health. Inadequate and unhygienic sanitation practices have severe consequences for public health and socio-economic development. This study examines the levels and trends in access to latrine facilities, spatial variations and the associated socio-economic factors in India. Data drawn from the National Sample Survey Organization's (NSSO) 69th (2012) and 76th rounds (2018) were used in this study. Moran's 'I' statistic and Local Indicators of Spatial Association (LISA) were applied to assess the spatial variations in access to latrine facilities. Bivariate and multivariate logistic regressions were employed to examine the factors associated with latrine use. The findings revealed that access to sanitation facilities is unsatisfactory, and there is a huge rural–urban gap in latrine use. Unequal access among socio-economic groups is also very prominent. The study found substantial geographical variations in latrine use across the country; open defecation is highly prevalent in eastern and central regions of the country, while the north and north-eastern regions have better access to latrine facilities. Factors like education, occupation, socio-religious affiliation, water availability, and economic status are significant determinants of accessibility to latrine. It is recommended that targeted interventions for the socio-economically disadvantaged groups, spreading awareness about the importance of latrine use and hygienic practices, and proper assistance for construction and maintenance of toilets could be helpful to combat the harmful practice of open defecation and ensure adequate and equitable sanitation for all.


According to some grammarians the use of the historical present tense is a technique for enhancing the dramatic effect of a story by making addressees feel as if they were present at the time of the experience, witnessing events as they occurred. Others have suggested that the historical present represents events as if they were occurring before the speaker's eyes. My own position on the matter, though, is that the necessity to postulate a "metaphorical shift", an "as if", is due to the interpretation of the basic meaning of the present as being contemporality with the speaker's present and the identification of a speaker (narrator) with an "intradiegetic" participant in the story (character). In support of this position the paper argues that the temporal referential of the present tense is the speech referential, organised by and around the speaker/character. The speech process is an incomplete process with a validation interval closed to the left and open to the right. This property motivates use of the present as a gram-matical vehicle for re-presentation.


High-efficiency multifunction solar cells are attracting a great deal of attention for both space and terrestrial applications. We proposed the monolithic integration of the II/VI (ZnCdMg)(SeTe) and the III/V (InAlGa)(AsSb) material systems for multijunction solar cells. These material systems have direct bandgap, zinc blende, quaternary alloys, lattice-matched to GaSb substrates that cover the entire optical spectrum from greater than 3.0 eV to less than 0.4 eV; enabling the fabrication of high quality multijunction solar cells (with an arbitrary number of junctions) that are well matched to the solar spectrum.


To reconstruct the evolution of ore‐forming fluids and determine the physicochemical conditions of deposition associated with seafloor massive sulfides, we must better understand the sources of rare earth elements (REEs), the factors that affect the REE abundance in the sulfides, and the REE flux from hydrothermal fluids to the sulfides. Here we examine the REE profiles of 46 massive sulfide samples collected from seven seafloor hydrothermal systems. These profiles feature variable total REE concentrations (37.2–4092 ppb) and REE distribution patterns (LaCN/LuCN ratios = 2.00–73.8; (Eu/Eu*)CN ratios = 0.34–7.60). The majority of the REE distribution patterns in the sulfides are similar to those of vent fluids, with the sulfides also exhibiting light REE enrichment. We demonstrate that the variable REE concentrations, Eu anomalies, and fractionation between light REEs and heavy REEs in the sulfides exhibit a relationship with the REE properties of the sulfide‐forming fluids and the massive sulfide chemistry. Based on the sulfide REE data, we estimate that modern seafloor sulfide deposits contain approximately 280 t of REEs. According to the flux of hydrothermal fluids at mid‐ocean ridges (MORs) and an average REE concentration of 3 ng/g in these fluids, hydrothermal vents at MORs alone transport more REEs (>360 t) to the oceans over the course of just 2 years than the total quantity of REEs in seafloor sulfides. The excess REEs (i.e., the quantity not captured by massive sulfides) may be transported away from the systems and become bound in sulfate deposits and metalliferous sediments.


Bistable nonlinear optical interfaces have potential advantages of lower absorption and higher switching speed over resonator-based bistable optical gates. The design of parallel vector multipliers based on all-optical logic gates on a nonlinear optical interface is proposed in this letter. These schemes can be extended to parallel multiplications of matrices and to photonic switching.

The image de-noise method brings about edge blur and the loss of details.According to wavelet scale correlation theory and classic threshold de-noise algorithm,the paper puts forward a new image de-noise algorithm.The method uses the correlation of different scales of wavelet coefficient to distinguish the corresponding wavelet coefficients between original images and noise.The former is reserved and the latter is treated with threshold de—noise algorithm on the basis of taking wavelet coefficients as the confidence degree of original image.The experiment results show that the method can achieve good image de-noise and reserve the edge and detail information of the original image well.


Recent findings show possible links between the development of neurodegenerative diseases such as Alzheimer's disease and olfactory deficiency. In the NEMRO project 1 , we therefore intend to explore objectively the olfactory neuroepithelium in order to assess the occurrence of neuropathological changes for neurodegenerative diseases. This implies to develop a tool for in vivo exploration of olfactory cells to be used at a research level, on selected patients. OCT imaging appears as a very interesting modality for the inspection given its resolution, depth of inspection, and the possibility of using an optical fiber-based OCT probe. The challenge is to bring such a probe in the area of interest, the so-called olfactory cleft, a very narrow zone in the upper area of the nose. This cannot be performed today with existing manual instruments. We thus introduce the current developments in the design of a new robotic platform, with the synthesis of a dedicated concentric tube robot (CTR).

This paper proposes a special design of a dual stator radial type permanent magnet vernier machine (PMVM) having a yokeless rotor to improve the torque density. The PMVM model is designed with winding only in the outer stator, while the inner stator is kept auxiliary without winding. The proposed model reduced the overall volume of the machine, which in turn improved the torque density of the machine. The proposed configuration makes the design free from thermal and manufacturing issues due to the absence of inner stator winding. The detailed specifications and analysis results of the proposed model, such as torque, back EMF, inductance, and other features, are presented in this paper. The model is analyzed and compared with the dual stator radial type PMVM having a yokeless rotor and dual stator winding using the 2D-Finite Element Method (FEM) as well as 3D Co-simulation with Ansys Mechanical.


The purpose of this study was to make a comparison between entry and exit levels of knowledge for the principles-of-marketing course given at a junior college and at a four-year institution of higher education. It was hoped that any significant difference in entry level or exit level knowledge would help in the formulation of future statements of articulation. Of additional interest was any variation in net change of level of knowledge between students taking the principles course at the junior college compared to those taking the course at a senior institution. Achievement of a given level of knowledge was considered to be imperative for future courses of study in the field of marketing. Data were collected by administering an identical pretest and posttest to students at Meramac Junior College and Southern Illinois University at Edwardsville. The preand posttests, each of which contained fifty multiple choice questions, were contructed from questions provided in the teaching manuals that accompanied the two texts being used. An equal number of questions was taken from each teaching manual. In the best judgment of the researchers the level of difficulty of the questions utilized did not vary from the pretest to the posttest. In addition, the selection of topics from which the questions were taken was consistent for both the preand posttest. Generally speaking the questions included on the posttest were different from those included on the pretest, but a few questions utilized on the pretest were also included on the posttest as a check of reliability.


This study examines the use of a covalently selenium-bonded peptide and phage that binds to the Yersinia pestis F1 antigen for the targeting and killing of E. coli expressing this surface antigen. Using a Ph.D.-12 phage-display library for affinity selection of the phage which would bind the F1 antigen of Y. pestis, a phage displaying a peptide that binds the F1 antigen with high affinity and specificity was identified. Selenium was then covalently attached to the display phage and the corresponding F1-antigen-binding peptide. Both the phage and peptides with selenium covalently attached retained their binding specificity for the Y. pestis F1 antigen. The phage or peptide not labeled with selenium did not kill the targeted bacteria, while the phage or peptide labeled with selenium did. In addition, the seleno-peptide, expressing the F1 targeting sequence only, killed cells expressing the F1 antigen but not the parent strain that did not express the F1 antigen. Specifically, the seleno-peptide could kill eight logs of bacteria in less than two hours at a 10-µM concentration. These results demonstrate a novel approach for the development of an antibacterial agent that can target a specific bacterial pathogen for destruction through the use of covalently attached selenium and will not affect other bacteria.

Two new methods to determine Wigner's angle in special relativity are presented. The first one consists in calculating the angle between the compositions ⊕ and ⊕ of the two non-collinear velocities and . In another method we introduce a generalization in the complex plane of Einstein's addition law of parallel velocities.


In this paper, spatially homogeneous anisotropic axially symmetric holographic dark energy cosmological model with generalized Chaplygin gas is obtained in a scalar–tensor theory of gravitation proposed by Brans and Dicke (Phys. Rev. 124, 925 (1961)). To obtain a determinate solution of the field equations we have used a power law between the metric potentials. It has been found that the anisotropic distribution of dark energy leads to the present accelerated expansion of the Universe. All the models obtained and presented here are expanding, non-rotating, and accelerating. Also some important features of the models including look-back time, distance modulus, and luminosity distance versus redshift, and their significances are discussed.


(1) Estimated levels of larval parasitism of the armyworm Mythimna separate (Walker) before and after the introduction of the parasitoid Apanteles ruficrus (Haliday) from Pakistan suggest that there has been an increase in average parasitism from c. 50-55% to c. 80%. Larval parasitism is not density dependent. (2) M. separate pupal parasitism is density dependent. (3) A. ruficrus parasitism reduces M. separate larval food consumption. The increased parasitism following the introduction of A. ruficrus is judged to have raised the armyworm population damage threshold in maize from c. 240-360 larvae m-2 to 400-530 larvae m-2. (4) The success of A. ruficrus in drastically reducing the pest incidence of M. separate is discussed in relation to its role in reducing food consumption as opposed to its lowering the average population levels of M. separate. (5) It is concluded that the ability of A. ruficrus to reduce the feeding potential of M. separate populations is probably the most important factor in its success as a biological control agent in New Zealand.


Forest biomass is one of the key parameters that indicate temporal change of the global continental carbon volumes, and its global estimation is required as described in the Kyoto protocol. NASDA's ALOS science project strongly intends its estimation either solely by SAR or in conjunction with the other optical sensors and the ground truth data. There have been (or are being) developed SAR based methods to estimate the forest biomass, which utilize the relationship between sigma-zero and biomass quantity, those based on coherence of one day separated C band data and L band radar intensity, and those based on forest tree heights and biomass quantities, etc. For the third category, it is expected that Pol-In-SAR might relate the interferometric phase difference at different polarizations to the tree structures and heights, and two-frequency interferometry relates to the phase center difference to the tree height.


Venous refilling time (VRT) can diagnose the presence of venous diseases in lower limbs. In order to calculate VRT it is necessary to determine the End of the Emptying Maneuvers (EEM). First Derivative Method (FDM) can be employed for automatic detection of the EEM, but its sensitivity to artifacts and noise can degrade its performance. In contrast, studies report that Area Triangulation Method (ATM) evinces effectiveness in biosignals point finding. This work compares the exactness of ATM and FDM for recognition of the EEM. The annotations made by 3 trained human observers on 37 photoplethysmography records were used as a reference. Bland-Altman graphics supported the analysis of agreement among human observers and methods, which was complemented with Analysis of variance and Multiple Comparisons statistical tests. Results showed that ATM is more accurate than FDM for automatic detection of the EEM, with statistically significant differences (p-value < 0.01).


We address the task of estimating sparse structured precision matrices for multivariate Gaussian random variables within a graphical model framework. We propose two novel estimators based on the Ordered Weighted ${\ell _1}$ (OWL) norm: 1) The Graphical OWL (GOWL) is a penalized likelihood method that applies the OWL norm to the lower triangle components of the precision matrix. 2) The column-by-column Graphical OWL (ccGOWL) estimates the precision matrix by performing OWL regularized linear regressions. Both methods can simultaneously identify groups of related edges in the graphical model and control the sparsity in the estimated precision matrix. We propose proximal descent algorithms to find the optimum for both estimators. For synthetic data where group structure is present, the ccGOWL estimator requires significantly reduced computation and achieves similar or greater accuracy than state-of-the-art estimators. Timing comparisons are presented and demonstrate the superior computational efficiency of the ccGOWL. We demonstrate the efficacy of the ccGOWL estimator on two domains—gene network analysis and econometrics.


This article examines the problem of legislative entrenchment through a particular focus on federal fiscal policy. The conventional academic debate about legislative entrenchment centers on hard entrenchment, but hard entrenchment is highly improbable – perhaps simply impossible – under the constitutional framework for federal legislation. By contrast, soft entrenchment is far more common. Of particular importance for fiscal policy is the incidental soft entrenchment induced by the structures of legislative organization, such as the congressional committee system and institutional voting procedures. Such structures bring stability to the federal budget process, to social-welfare entitlements, and to tax expenditures. Weakening those structures in order to make fiscal policy more flexible may compromise internal legislative stability, legislative information, and legislative dealmaking.


Purpose
Using a cross-cultural perspective, the purpose of this paper is to examine the effect of cultural difference and travel motivation on event participation and how cultural difference may influence the relationship between travel motivation and event participation. The paper highlights the importance of culture in tourism research.

Design/methodology/approach
The research was conducted by using a secondary data set (n=24,692) commissioned by Destination Canada (formerly the Canadian Tourism Commission). Both descriptive statistics (e.g. frequency analysis) and inferential statistics (e.g. hierarchical regressions) were calculated.

Findings
First of all, the results indicated that travel motivations and cultural difference can impact event participation. For example, those who were more motivated by knowledge and competence (e.g. knowing history and culture) were more likely to participate in art festivals and cultural events. Also, the research recognized that Asian-Canadians were more likely to visit ethnic or religious festivals than Anglo-Canadians, whereas Asian-Canadians were less likely to attend farmers' market in comparison with Anglo-Canadians. Last, the effect of cultural difference can moderate the relationship between travel motivation and event participation.

Originality/value
These findings emphasize that travel motivations and cultural difference are key factors to be considered for festivals' marketing. Particularly, the moderating effect of cultural difference reinforces that the important role played by culture for effective festival marketing should not be ignored. The research also provides valuable insights for destination managers who are interested in Asian markets. Moreover, using a secondary data set prepared by the Canadian Government largely increased the results' representativeness, trustworthiness, and generalizability.

Significance Information processing in the central nervous system relies on chemical synapses where neurotransmitters such as the inhibitory neurotransmitter γ-aminobutyric acid (GABA) are released at presynaptic nerve endings. GABA is synthesized by glutamic acid decarboxylase (GAD), an enzyme requiring pyridoxal 5'-phosphate (PLP or vitamin B6) as cofactor, the latter being synthesized by pyridoxal kinase (PDXK). Here, we show that the antimalarial drug artemisinin inhibits PDXK and describe the structural basis of this inhibition. The decrease in PLP production reduces the amount of GABA being produced, which, in turn, impacts the efficacy of GABAergic transmission. This study combined with our previous data sheds light on how artemisinins can influence inhibitory synaptic transmissions both presynaptically, as described here, and postsynaptically. The antimalarial artemisinins have also been implicated in the regulation of various cellular pathways including immunomodulation of cancers and regulation of pancreatic cell signaling in mammals. Despite their widespread application, the cellular specificities and molecular mechanisms of target recognition by artemisinins remain poorly characterized. We recently demonstrated how these drugs modulate inhibitory postsynaptic signaling by direct binding to the postsynaptic scaffolding protein gephyrin. Here, we report the crystal structure of the central metabolic enzyme pyridoxal kinase (PDXK), which catalyzes the production of the active form of vitamin B6 (also known as pyridoxal 5′-phosphate [PLP]), in complex with artesunate at 2.4-Å resolution. Partially overlapping binding of artemisinins with the substrate pyridoxal inhibits PLP biosynthesis as demonstrated by kinetic measurements. Electrophysiological recordings from hippocampal slices and activity measurements of glutamic acid decarboxylase (GAD), a PLP-dependent enzyme synthesizing the neurotransmitter γ-aminobutyric acid (GABA), define how artemisinins also interfere presynaptically with GABAergic signaling. Our data provide a comprehensive picture of artemisinin-induced effects on inhibitory signaling in the brain.

sources for Rumanian studies at the Library of Congress. Its shortcomings can be explained largely by the incomplete nature of these holdings. Hence while useful as an introduction to the subject, it must be supplemented with bibliographies drawing upon the wealth of additional material available in Rumanian libraries. In history, for example, helpful lists can be found in the multivolume "official" work, Istoria Rominiei (1960—).


Mathematics skills are critical in engineering, yet many students enter university without sufficient proficiency. At the University of Southern Queensland (USQ), the Faculty of Engineering and Surveying (FoES) has a large number of external mature age students, many of whom have forgotten or never learnt these skills. We aim to improve students' completion and satisfaction rates in mathematics-based courses in first year engineering by incorporating more scaffolded learning into the materials. The specific objective of the research related to this paper is to identify forgotten concepts, troublesome knowledge, threshold concepts and 'stuck places' (Meyer & Land 2005, 2006) in mathematics. A survey of 31 staff in the Faculty of Engineering and Surveying described the relationships among the key mathematics areas and the USQ FoES courses. A focus group session with 16 mathematics staff identified the topics and concepts that the instructors thought were crucial. Individual interviews with four introductory mathematics instructors confirmed the results of the survey and focus group, and characterized the underlying threshold concepts of select topics. The results of this data will be used to develop learning objects and materials.


This article examines how consumers' attitudes toward advertisements are affected by their previous exposure to them. The results of our experiment suggest that the effects of exposure on ad attitudes may be moderated by the complexity of the advertisement: evaluations of complex ads become more positive with exposure, while those of simple ads do not. This finding may help explain why previous studies of ad exposure effects have yielded mixed results.


Vascular grafts made of expanded polytetrafluoroethylene (ePTFE) are widely employed in reconstructive surgery. Despite their successful use for replacement of large diameter blood vessels, ePTFE vascular grafts with internal diameters of less than 6 mm uniformly fail as a result of blood clot formation. To reduce the ePTFE reactivity to platelets, a new method for membrane construction on the inner graft surface was developed. The membrane, made of a chitosan-poly(vinyl alcohol) blend and non-ionic detergent, is constructed by adsorption of a thin liquid film and air drying. The chemically modified ePTFE surface exhibits both morphological changes and a markedly reduced reactivity to platelets in in vitro studies. Chemical activation of the chitosan-poly(vinyl alcohol) blend, to trigger desired protein binding, may yet serve as a complementary surface modification approach. © 1997 John Wiley & Sons, Inc.

The management plans presently being carried out are, in the majority, a forest exploitation done with as if it were a management plan. This work was carried out in order to help differentiate these two types of exploitations. It was aimed at verifying the sustainability of the Cerrado management plan carried out on Santa Cecilia farm, in the municipality of Joao Pinheiro, in the State of Minas Gerais, Brazil, through the structural analysis of the vegetation, identifying some of its impacts in relation to a non exploited cerrado area. The evaluation was made by plots that were established in the explored area in 1994/95 and in the non explored area. The results of the horizontal structure analysis showed that there were significant differences in the absolute density and the total volume and absolute dominance between the areas studied. The results of diametric structure showed a significant difference for the density distribution and between the basal area and total volume. These results indicate that the exploration was done beyond the limits that could allow the recovery of the vegetation for a new harvest at the end of rotation cycle.


This paper describes MORENA (Multimedia ORganization Employing a Network Approach), a Petri-net based platform for the description and execution of hypermedia applications. All the parts that compose the application, such as sound, video, text and buttons are described in this model and the browsing semantics are also specified. The MORENA model provides support for dynamic data, such as video or audio. It also provides structured authoring, fine-grained synchronization of media, flexibility and adaptability through message passing, user interaction, easy prototyping and simulation, and the ability to reuse logical specifications. MORENA's parent is Trellis, but it was influenced by many other systems, merging their features in a coherent and consistent framework. Applications written based on the MORENA model are compact and platform independent.

A process called emergency permits allows counselors-in-training to be employed as school counselors throughout the state of Texas. Using a phenomenological approach, authors explored the experiences of counselors-in-training working as public school counselors through the emergency permit process. Seven themes emerged from semi-structured interviews with five participants. Authors addressed implications of the study and discussed directions for future research.


This study was carried out to estimate the heritabilities of body weights and body measurements and to estimate the genetic and phenotypic correlation coefficients on the baisis of the records obtained from 6,226 heads of Korean Native Cow raised at Hanwoo Purebreeding Region of 8 provinces from 1984 to 1994. The generic parameters were estimated by the Becker`s(1985) methods utilizing the variance components of sire. The heritability estimates of the body weights at birth and 4 months of age were 0.262?.044 and 0.48710.085, respectively. The heritabilies of body weight, withers height, rump height, body length, chest girth, chest depth, chest width, rump length, rump width, thud width and hipbone width at 24 months of age were estimated as 0.189±0.056, 0.259±0.056, 0.182±0.042, 0.090±0.026, 0.132 ±0.033, 0.195±0.045, 0.194±0.044, 0.149±0.037, 0.124±0.032, 0.188±0.043 and 0.228±0.050, respectively. The genetic and phenotypic correlation coefficients between the birth weight and the weaning weight were estimated as 0.227 and 0.125, respectively. `These lower relationships were in contrast with other reports that heavier calf at birth grew faster till weaning than lighter calf at birth. The genetic correlation coefficients of the body weight with the withers height, rump height, body length, chest girth, chest depth, chest width, rump length, rump width, thurl width and hipbone width at 24 months of age were estimated as 0.534, 0.399, 0.173, 0.745, 0.578, 0.695, 0.395, 0.414, 0.450 and 0.114, respectively. `The Genetic correlations of the body weight with the chest girth, chest width, chest depth and withers height were high, while those with the hipbone wide and body length were extremly low. In general, the body weights seemed to have closer relationship with the development of fore quaters than with that of hind quaters of the Korean Native Cattle. The phenotypic correlation coefficients of the body weight with the withers height, rump height, body lengdt, chest girth, chest depth, chest width, rump length, rump width, thud width and hipbone width at 24 months of age were estimated as 0.378, 0.361, 0.465, 0.793, 0.587, 0.575, 0.425, 0.516, 0.407 and 0.354, respectively.

In this paper we create a model to evaluate the uncertainty in determination of chemical oxygen demand in water sample by titration,and give sensitivity coefficient of each uncertainty component.It appears that the final value of COD is directly from the uncertainty components which include (NH_4)_2Fe(SO_4)_2 concentration,titration of sample against (NH_4)_2Fe(SO_4)_2 (V_1),titration of blank against (NH_4)_2Fe(SO_4)_2 (V_0) and transfer volume of sample.We calculate each uncertainty and give the expanded uncertainty.


In recent years, with the rapid development of deep learning, the requirements for the performance of the corresponding real-time recognition system are getting higher and higher. However, the rapid expansion of data volume means that time delay, power consumption, and cost have become problems that cannot be ignored. In this case, the traditional neural network is almost impossible to use to achieve productization. In order to improve the potential problems of a neural network facing a huge number of datasets without affecting the recognition effect, the model compression method has gradually entered people's vision. However, the existing model compression methods still have some shortcomings in some aspects, such as low rank decomposition, transfer/compact convolution filter, knowledge distillation, etc. These problems enable the traditional model compression to cope with the huge amount of computation brought by large datasets to a certain extent, but also make the results unstable on some datasets, and the system performance has not been improved satisfactorily. To address this, we proposed a structured network compression and acceleration method for the convolutional neural network, which integrates the pruned convolutional neural network and the recurrent neural network, and applied it to the lip-recognition system in this paper.


I studied ecology and behavior of wintering Black-throated Blue Warblers (Dendroica caerulescens) at three sites on Puerto Rico over four years. The site with tall mature forest and relatively few fruiting understory plants had warbler populations characterized by: a predominance of males; relatiyely early fall arrival of returning adults; high site fidelity; large home ranges; low density of sedentary birds; few wandering individuals; high over- winter persistence of sedentary birds; and an invertebrate-rich diet. In contrast, the shrubby second-growth site with an abundance of fruiting plants had warbler populations charac- terized by: a predominance of females; relatively late arrival of returning adults compared to juveniles; low site fidelity; small home ranges; high density of sedentary and wandering birds; low overwinter persistence of sedentary birds; and a nectar- and fruit-rich diet. At the third site, the population traits fell within these extremes. Some site variation is attributable to sex differences in site persistence, wandering, and home-range size, which appear as population differences only because sex ratios vary among sites. However, differences in abundance and seasonality of fruit and nectar may further contribute to site differences in overwinter persistence of sedentary birds, wandering, home-range size, and density.

ECQV implicit certificates are special public-key certificates, proposed for smaller size and faster verification. In resource-constrained environments such as Internet of Things (IoT), it's common to replace X.509 certificates with ECQV implicit certificates for better efficiency. Google's Certificate Transparency (CT) makes the certificate issuance be publicly-visible to everyone, to enhance the trustworthiness of Public Key Infrastructure (PKI). However, the conventional CT approach based on Signed Certificate Timestamp (SCT) will be a burden for ECQV certificate verifiers in resource-constrained environments. In this paper, we propose an efficient scheme, named ECQV Implicit Certificate Transparency (EICT), to integrate CT with implicit certificates following the same assumption and approach of ECQV implicit certificates. EICT obtains better performance than CT applied in traditional X.509 PKIs. We also conduct the security analysis and performance evaluation of the proposed scheme.


The Standard Model is a model of particle physics in which one Higgs particle has been confirmed with a mass of 126 GeV. In 2016 some discoveries made it possible to have other scalar particles similar to the Higgs. The modified left-right symmetric model extends the standard model with an expanded scalar sector. There are ϕ_L and Δ_L left sector scalar particles, ϕ_L and Δ_L right sector scalar particles and two singlet η and ξ scalar particles. Therefore, this research objective is to analyze of the possibility of a Higgs interaction with other scalar particles. The method of this research is using a Feynman diagram to describe the interaction terms at the Higgs Potential. The interaction probability is sought using the Feynman rule for Toy Theory. The decay rate uses the Golden Rule. When the universe's temperature reaches the mass of η, the scalar becomes non-relativistic and decays into ϕ_L and ϕ_R. The scalar ξ is scattered into ϕ_L through the η scalar propagator and into ϕ_R. The scalars Δ_L and Δ_R do not decay, they only scatter into ϕ_L and ϕ_R. The η and ξ scalars have transformed into ϕ_L in the left sector and ϕ_R in the right sector, and only ϕ_L in the sectors are likely to be detected as the Higgs Standard Model.


Cloud Computing is a new flair of computing in which real time scaling and virtualized resources are provided as services over the internet. The services provided by Cloud Computing can be grouped into three categories: software as a service, platform as a service, infrastructure as a service. Cloud technologies can help to reduce cost, reduce management responsibilities, increase agility and efficiency of organizations. There are various security issues for Cloud Computing as it comprises many technologies including networks, databases, operating systems, virtualization, resource scheduling, Transaction management, load balancing, concurrency control and memory management. Providing Data security is the crucial challenge in Cloud Computing . The Data security in Cloud Computing includes six aspects: Data-in-transit, Data–at-rest, Processing of Data, Data Lineage, Data Provenance, Data Remanence. Even though Many standards and solutions are developed by groups like The Cloud Security Alliance (CSA), and Open Web Application Security Project (OWASP), still there are Many challenges in Cloud Computing security. An architectural model is discussed to mitigate the data threats by enhancing key management system which aims to provide guaranteed computing dynamic environments for end-users.


Highlights

Social inquiry is much more than the study of society. It further excavates historical facts, critically reflects on everyday happenings, and envisions the future we wish to create.
The intent of initiating this dialogue on social inquiry is two-fold: a) to offer a sociological perspective (i.e. 'thinking sociologically'), and b) to expand our understanding of sociological thinking.
Sociological thinking can be developed by examining the periphery of the core.
Context matters in understanding any phenomenon under the sociological microscope.
Sociological thinking allows many different viewpoints to coexist within a larger structure and that it respects pluralism.
Sociological thinking is about developing or providing a perspective to examine social nuances.
Sociological thinking should act as a means for social transformation.
 Social inquiry serves as a methodology for the social sciences and humanities. It deals with the philosophy of social science and the workings of the social world – giving a way for understanding both the biosphere and the sociosphere.
