people of color. An angry Brian Freeman ("When We Were Warriors") challenges his black community: "Why do we other each other so in a community of others?" (250). Randy Gener ("The Kids Stay in the Picture, or, Toward a New Queer Theater") offers hope with School's OUT, a public program in New York City that brings together queer teenagers of color with theatre professionals to "explore the thistly themes in their lives—coming out, race, loneliness, sex, dreams and fears of the future, homophobia, racism, and AIDS—through art" (255). Another key tension running through the volume concerns the functions of queer theatre. Whereas coauthors David Román and Tim Miller (" 'Preaching to the Converted' ") attest to its power to forge community amid political struggle, David Savran ("Queer Theater and the Disarticulation of Identity") emphasizes its capacity to destabilize and disarticulate identity. Savran claims that "the necessity of multiple identifications and desires that theatre authorizes—across genders, sexualities, races, classes—renders it both the most utopian form of cultural production and the queerest" (164). So, Savran asks, why not include John Guare, Mac Wellman, and Suzan Lori-Parks among queer theatre's luminaries? His query prompts another, one not pursued in the volume's modern and contemporary coverage: What about the community-building and disarticulating operations of queerness and same-sex desire in ostensibly "straight," more conventionally canonical theatre? But when it comes to defining the lubricious boundaries of queer theatre, the volume only deserves credit for raising more questions than it answers. The critical point, made powerfully by all the essays, is that scholars and practitioners of queer theatre must continue to collaborate. In a moving endnote, Carmelita Tropicana evokes the memory of Frank Maya, an actor dying of AIDS backstage at the closing festivities of the 1995 conference. The special ephemerality and perilousness of queer existence onand offstage make this volume's excellently rendered project of documentation through performance, writing, and publication not only admirable and necessary but urgent.


Fast and accurate assessment of fire-damaged concrete structures is of great significance for later maintenance and reuse. The traditional methods require large amount of experimental efforts, and some other new technologies are expensive and their applicability still needs further investigation. In view of this, a colorimetric method based on the optical analysis is proposed to evaluate the fire damage of the concrete in terms of the translation of the color coordinates in the chromaticity diagram. Fire damage experiment was first conducted on concrete cubes with two different strengths. Photos were then taken under the conditions of daylight vs. fluorescent light, and manual white balance vs. auto white balance. The chromaticity diagram is constructed to represent the relationship between the coordinates of the concrete colors and the maximum temperature that concrete was subject to. The conditions under the daylight and the manual white balance are recommended for taking photos to construct the chromaticity diagram, and a linear equation was obtained to estimate the heating duration and the maximum temperature that the concrete exposed to from the coordinates of the concrete color. The results of this study will advance the technology of non-destructively assessing the fire-damaged structures.


In male dominated societies of the world women have been subjected to gruesome atrocities that has affected them physically, emotionally, sexually and morally. Particularly, if a woman is facing the unfortunate state of widowhood in a patriarchal society like India, she is being considered as a social stigma. They are excluded culturally, socially, economically and legally. At one hand they lost their husband and at the other hand they have to face discrimination of various kind and degree. In context of this line of thought, the present paper is an earnest attempt to describe the vulnerability of widows in Indian national. The paper largely based on review of various reports, literature and works done on the status and well being of widows in India try to throw light on the marginalized and sympathetic situation of widows in India, how it is a neglected area in the field of social research, its demographic portrayal and the question of social security of widows in Indian context. The paper concludes by advocating an urgent need for policy intervention for positive inclusion of this largely excluded section of the society.


Previously, polytetrafluoroethylene (PTFE) was believed to be a typical polymer decomposed by ionizing radiation. However, it was found that, when PTFE is heated to a high temperature near its melting point and subjected to ionizing radiation under an inert gas atmosphere, across-linking reaction occurs between its atoms. Technology based on this discovery was developed in Japan. The cross-linking technology and its characteristics were examined. We found that cross-linked PTFE drastically improves abrasion resistance and creep resistance. We established the elemental technology based on cross-linking.At present, we have developed a wide selection of basic materials according for various uses and furthured the development of applied products.


In the present scenario the depletion of conventional sources causes an energy crisis. The energy crisis causes load demand with respect to electricity. The use of renewable energy sources plays a vital role in reducing the energy crisis and in reduction of CO2 emission. The use of solar energy is the major source of power in generation as this is the root cause for the development of wind, tides, etc. However, due to climatic condition the availability of PV sources varies from time to time. Hence it is essential to track the maximum source of energy by implementing different types of MPPT algorithms. However, use of MPPT algorithms has the limitation of using the same during partial shadow conditions. The issue of tracking power under partial shadow conditions can be resolved by implementing an intelligent optimization tracking algorithm which involves a computation process. Though many of nature's inspired algorithms were present to address real world problems, Mirjalili developed the dragonfly algorithm to provide a better optimization solution to the issues faced in real-time applications. The proposed concept focuses on the implementation of the dragonfly optimization algorithm to track the maximum power from solar and involves the concept of machine learning, image processing, and data computation.


It is necessary to optimize clustering processing of communication big data numerical attribute feature information in order to improve the ability of numerical attribute mining of communication big data, and thus a big data clustering algorithm based on cloud computing was proposed. The cloud extended distributed feature fitting method was used to process the numerical attribute linear programming of communication big data, and the mutual information feature quantity of communication big data numerical attribute was extracted. Combined with fuzzy C-means clustering and linear regression analysis, the statistical analysis of big data numerical attribute feature information was carried out, and the associated attribute sample set of communication big data numerical attribute cloud grid distribution was constructed. Cloud computing and adaptive quantitative recurrent classifiers were used for data classification, and block template matching and multi-sensor information fusion were combined to search the clustering center automatically to improve the convergence of clustering. The simulation results show that, after the application of this method, the information fusion performance of the clustering process was better, the automatic searching ability of the data clustering center was stronger, the frequency domain equalization control effect was good, the bit error rate was low, the energy consumption was small, and the ability of fuzzy weighted clustering retrieval of numerical attributes of communication big data was effectively improved.

In this brief, we present a capacitance-to-digital converter (CDC) for one-terminal capacitive sensors. The designed CDC implements a digital correction technique to reduce nonidealities and noises, such as the offset, 1/f noise, and power supply noise. This correction technique can also minimize effectively the complexity of the analog front-end circuit. All sensor functions, including analog circuits (delta-sigma CDC, bandgap reference, and voltage regulator) and digital logics (microprocessor, memories, and interface logics), are integrated into a single chip and occupy approximately 90% of the area. The chip is fabricated in a 0.18-$\mu\mbox{m}$ standard CMOS process, which does not have a deep n-well stage. The analog and digital circuits, including the digital input/output pads, must share the same substrate in this design. However, the measurement results demonstrate highly effective resolutions of 16 to 17.4 b, which are achieved with different conversion times.


The study carried out during this thesis concerns a series of thermochronometric data analyses and micro-structural microscope observations on seven samples coming from the Brenner Basis tunnel, which aimes at connecting Italy with Austria. The samples were taken across the Pusteria Fault, one of the major fault of the Alps. The sections we classified and examined comprise granite rocks belonging to the Brixen Granite and post-orogenic intrusive igneous rocks belonging to the Tonalitic Lamella. The results show that the first ones are essentially undeformed while the second ones, in particular the nearest sample to the Pusteria Fault, exhibit a strong mylonitic foliation with clear cataclastic layers. On these samples, we conducted thermochronometric analyses by using the
(U-Th)/He thermochronometer to date apatites; dates appear to be deeply influenced by the presence of hot circulating fluids which caused a reset of the He system.


The application of the microcredit has undergone a very much interpretation among scholars. Some believe it would change the overall economic scenarios and some perhaps would rather picture it as a provision to service poor societies. The success factors of microcredit performance and its interpretation until now yet being highlighted. Thus, the aim of this paper is to look at intensity upon micro credit performance among women entrepreneurship where customer knowledge, customer managerial and customer attitude will use as a main variables. This study was preliminary tested via a random survey consists of 100 samples of customers at Amanah Ikhtiar Malaysia (AIM) in Kelantan. The data is analyzed using frequency distributions, reliability analysis, descriptive statistics, linear regression, pearson correlation and regression analysis via SPSS. Based on our findings we believed that all of variables selected are significant in the rank that customer managerial become the main success factors of microcredit to accelerate further in sustainability of women entrepreneurships in Kelantan as well as Malaysia in overall.


ABSTRACT:On June 26, 1917, copper miners in the border town of Bisbee, Arizona, went on strike. The companies they worked for had refused demands put forth by the Industrial Workers of the World (IWW) for higher pay, safer working conditions, and an end to wage discrimination against Mexican miners and union members. Rather than negotiate, the companies worked with the local sheriff to deputize a "posse" of 2,000 men to deport the strikers. Early in the morning on July 12, the vigilantes roused the miners from their beds at gunpoint, loaded them onto cattle cars, and sent them on a sixteen-hour, 200-mile trip across state lines to Columbus, New Mexico. They were told never to return, on threat of death. One hundred years later the town of Bisbee staged a reenactment of the deportation in collaboration with filmmaker Robert Greene, whose Bisbee '17 was released in theaters last September.

O NE OF THE SIGNIFICANT ELEMENTS Of the regional dependency effect of federal land ownership derives from the fact that federal lands are exempt from taxation by state and local governments.1 If these lands were evenly distributed throughout the United States there would be no peculiar adverse impact on a specific set of state and local governments because of this tax exempt status. However, the empirical context within which the impact of and problems associated with this tax void must be analyzed is an extreme concentration of about 95 per cent of federal lands in the eleven western states and Alaska.2 Federal land concentrations range from about 29 per cent of the land base in the State of Washington to about 86 per cent in Nevada and 96 per cent in Alaska-and remove precisely that much land from state and local land tax bases. This


The utilization of sustainable concrete in producing reinforced concrete structures subjected to seismic actions is one of the leading research topics of recent years. With the technical exhibition that this concrete may be used in conventional reinforced concrete structures, a significant threshold for this sustainable material is accomplished. In the scope of this study, the seismic behavior of five different reinforced concrete structures under seismic actions, which are considered to be produced from sustainable concrete and conventional concrete, was investigated in detail. The geometrical, cross-section, and longitudinal section dimensions of these reinforced concrete structures are convenient for the equivalent seismic load method to use effectively. Furthermore, the Turkish Building Seismic Code limits were considered for the numerical simulation of reinforced concrete structures. Based on this detailed seismic simulation, the equivalent seismic load method may be used in earthquake simulation of reinforced concrete structures incorporating sustainable concrete. Furthermore, the numerical simulation results obtained from the sustainable concrete structures were extensively compared with the conventional concrete structures results. It may be concluded from these results that there are negligible differences between the seismic performance indicators of reinforced sustainable concrete structures and conventional concrete structures.


The use of a family of time-frequency shifted versions of a prototype signal, namely Weyl-Heisenberg (WH) sets, is a common feature of various concepts in signal analysis, processing and digital communication. The authors discuss the matching of WH prototype signals to important nonstationary environments. The statistical window optimization for the STFT/Gabor expansion of nonstationary processes is shown to be formally equivalent to optimal signal design for narrowband WSSUS channels. For the case of underspread channels/processes the authors derive approximate solutions to the optimization problem.<<ETX>>


This article explores the early history of Roman exemplary literature through the case study of the elder Cato's account of his imitation of the parsimony and self-sufficiency of M'. Curius Dentatus. I reconstruct from Cicero, Plutarch, and other sources a Catonian prose text that unified the exemplary narrative of Curius' refusal of a bribe from Samnite emissaries with an evocative location at the hearth of a humble Sabine farmstead, an approving "audience" in Cato himself, and a model for the replication of Curius' virtue. The narrative itself served as the monumentum for the exemplum, and its details are often evoked in place of the exemplary deed itself. I argue that this narrative is both a very early instance of exemplary literature and a self-conscious reflection on the power of literature to transcend temporal and spatial limitations and to extend cultural models for the familial replication of elite virtues to a broader audience.


Purpose To determine which factors affect the recovery of visual function in macula off rhegmatogenous retinal detachment (RRD). Methods In a prospective study of forty-five patients with a primary macula-off RRD of 24 hours to 6 weeks duration, the height of the macular detachment was determined by ultrasonography. At 12 months postoperatively, best corrected visual acuity (BCVA), contrast acuity, and color confusion indexes (CCI) were obtained. Results Macular detachment was present for 2–32 (median 7) days before repair. A shorter duration of macular detachment was correlated with a better CCI saturé (p = 0.0026) and lower LogMAR BCVA (better Snellen visual acuity)(p = 0.012). Also, a smaller height of macular detachment was correlated with a lower LogMAR BCVA (p = 0.0034). A younger age and lower pre-operative LogMAR BCVA at presentation were both correlated with better postoperative contrast acuity in the total group (age: p = 1.7×10−4 and pre-operative LogMAR BCVA: p = 0.0034). Conclusion Functional recovery after macula-off RRD is affected by the duration and the height of the macular detachment. Recovery of contrast acuity is also affected by age and BCVA at presentation.

Van der Waals heterobilayers formed by vertically stacked two-dimensional materials could be a viable candidate for optoelectronics. This study carried out first-principles calculations to study the geometrical, electronic and optical properties of heterobilayers consisting transition metal dichalcogenide (TMDC) SnSe2 and Janus TMDCs ZrSSe and SnSSe. Eight possible configurations SeSnSe–SSnSe (I), SeSnSe–SeSnS (II), SeSnSe–SZrSe (III), SeSnSe–SeZrS (IV), SSnSe–SZrSe (V), SSnSe–SeZrS (VI), SeSnS–SZrSe (VII) and SeSnS–SeZrS (VIII) are dynamically, thermally, energetically and mechanical stable. Six configurations, (I, II, III, IV, V and VI) have indirect band gaps with type-II band alignments, enhancing carrier lifetime an essential feature for potential applications in photovoltaic and nanoelectronics devices. In contrast, VII and VIII have indirect band gap with a type-I band alignment, facilitating efficient recombination of electron–hole pairs under high irradiation. All heterobilayers demonstrated significant optical absorption in the visible region. These findings highlight the potential utilization of heterobilayers in electronic and optoelectronic devices.


The factors that determine intentions to relocate in the continental U. S. among Puerto Rican nursing professionals were explored. One hundred and eleven nursing students in their last semester of nursing school responded to a biographical questionnaire. Intentions to relocate were regressed on factor scores resulting from factor-analyzing questionnaire items. The results indicated that the individual's level of independence (e. g., lack of family attachment) was the best predictor of intentions to relocate. In addition, both lack of fear of discrimination and being at a middle life stage were positively related to intentions to take a job in the U. S. Implications for further study of the motivations driving culturally diverse laborforce entrants are discussed.


OZENS of articles have been written about St. Bernardine the "Popular Preacher," the "Apostle of Italy," the "Pillar of the Observance," "Herald of the Holy Name," and the like. There is one aspect of the Saint, however, which has not been adequately emphasized, a characteristic which seems to send its cry for publicity ringing down through the five centuries separating his day and ours. W e have not heard enough about St. Bernardine, the Friend. For a reformer, it is surprising how many friends St. Bernardine had. Though he worked to reform both his order and country, de nouncing and correcting where such procedure was necessary, he won many and great friends among his Franciscan confreres and fellow-Italians. We speak of Bernardine's friendships. They embraced many persons in varying degrees of intensity and intimacy. By instinct and by study the Saint knew the value of Sacred Scripture too well to have neglected the sound advice of the Holy Spirit given in Ecclesiasticus 6:14-16: "A faithful friend is a strong defence; and he that hath found him hath found a treasure. Nothing can be compared to a faithful friend___A faithful friend is the medicine of life and immortality: and they that fear the Lord shall find him." On second thought, it is not so surprising that many should have been eager to call Bernardine their friend. He had an abundance of natural good qualities on which grace built solidly. We have St. John Capistran's word for it that Bernardine never got excited, even when correcting others.1 Aeneas Sylvius tells us that despite the Saint's emaciated features — nature's tribute to life-long mortifica tion — Bernardine's face always shone with true Franciscan joy and never knew a frown or the appearance of sadness.2 And there is that


riel, nun of Wilton, and the anonymous nuns who contributed their poetry to the mortuary rolls that circulated in England and Normandy. The linear chronological layout of the book has the advantage that specific political circumstances of the queens and other high-status women involved in literary patronage can be explained. In particular, it allows for in-depth discussion of the impact of dynastic change and conquest by Danish and Norman forces in eleventh-century England. This is an impressive study that I recommend in the strongest possible terms. A real delight to read.


Electromagnetic fields (EMFs) are a class of non ionizing radiation that is invisible line of force present everywhere in our environment and produced by electrically charged objects [1]. A magnetic field results from the flow of current through wires or electrical devices. Human is daily exposed to EMFs from natural sources [2]. Increase in the level of environmental exposure to EMFs was reported during the twentieth century with the spread of the utilization of electricity in almost every aspect of civil and domestic life [3]. In modern society, it is impossible to avoid exposure to EMFs produced by power lines and many kinds of electrical appliance and underground cables [4].


Motivated by applications to low-latency secret key generation in physical-layer security, we study Polarization-Adjusted Convolutional (PAC) codes for source coding with side information. Source PAC codes operate in a dual manner to channel PAC codes by introducing a rate-one convolutional code after the polarization transform. The decoding of source PAC codes requires a careful scheduling of the successive cancellation decoder and a careful optimization of the rate profiling. Our empirical results demonstrate the improved performance of source PAC codes over regular polar codes using Successive Cancellation List (SCL) decoding. We illustrate the performance in terms for key generation rate in a secret-key generation setup over an Additive White Gaussian Noise (AWGN) channel, suggesting that PAC codes could improve the performance of physical-layer security schemes at short blocklength.


We investigate the joint uplink-downlink configuration of an intelligent reflecting surface (IRS) for multi-user frequency-division-duplexing (FDD) and time-division-duplexing (TDD) systems. This is motivated in FDD since uplink and downlink transmissions occur simultaneously and hence an IRS must be jointly configured for both transmissions. In TDD, while a joint design is not strictly necessary, it can significantly reduce feedback overhead, power consumption, and configuration periods associated with updating the IRS. To compute the trade-off between uplink and downlink rates achieved by a joint design, a weighted-sum problem is formulated and optimized using a developed block-coordinate descent algorithm. The resulting uplink-downlink trade-off regions are investigated by numerical simulation to gain insights into different scenarios. In all FDD scenarios and some TDD scenarios, the jointly optimized design significantly outperforms the fixed-uplink (fixed-downlink) heuristic of using the IRS configuration optimized for uplink (downlink) to assist downlink (uplink) transmissions. Moreover, the joint design substantially bridges the gap to the individual design upper bound of allowing different IRS configurations in uplink and downlink. Otherwise, in the remaining TDD scenarios, the fixed-uplink and fixed-downlink designs nearly achieve the individual design performance and substantially reduce overhead and/or complexity compared to the optimized joint design and individual design.


Abstract This study addresses questions pertaining to the effective use of habitat suitability models as tools for biodiversity assessment in forest management. Specifically, it discusses, in relation to recent literature, how habitat suitability models could be made more accountable for the multidimensionality of the biodiversity concept, means to generalizing single-species models and addressing population viability, and how to integrate habitat suitability models and forest management planning. Single-species models dominate in the literature, but working with many species, e.g. the focal species concept, provides a feasible option to broaden the conceptual scope of habitat suitability models as tools for biodiversity assessment. The advent of spatially explicit models scaled to the ecologies of species has made habitat suitability models better able to deal with habitat quality and to identify and quantify functional habitat at different spatial scales. The output of habitat suitability models as spatial templates for the simulation of population dynamics is increasingly used to address population viability. Linking species' habitat requirements with landscape projection models and scenario analysis is the important next step to take in order to make habitat suitability models more efficient as planning tools in forest management.


We investigate the impact of strategic investors on bank efficiency in the context of regional economic development. The data on Chinese city commercial banks operating regionally are well-suited for the study. Findings suggest that strategic investors significantly increase efficiency in Chinese city commercial banks; the impact of strategic investors on the efficiency of Chinese city commercial banks is negatively correlated to the level of regional economic development. The negative correlation of the impact of strategic investors on Chinese city commercial banks' efficiency with regional economic development may be explained by the mix of the local official promotion system and the city commercial banks' governance structure.


Chemotactic cytokines or chemokines play pivotal roles in various processes such as immune surveillance, organ development, angiogenesis, and immune responses. Expression profiling of chemokines, especially those involved in inflammation and immune disorders, is important in achieving a deeper understanding of disease states. Using fluorescence-encoded beads, we have developed two multiplex immunoassay panels to simultaneously detect 13 human or mouse chemokines, respectively. Both human and mouse panels include MCP-1 (CCL2), RANTES (CCL5), IP-10 (CXCL10), Eotaxin (CCL11), TARC (CCL17), MIP-1α (CCL3), MIP-1β (CCL4), MIG (CXCL9), and MIP-3α (CCL20). In addition, the human panel contains ENA-78 (CXCL5), GROα (CXCL1), I-TAC (CXCL11) and IL-8 (CXCL8), and the mouse panel contains LIX (CXCL5), KC (CXCL1), BLC (CXCL13) and MDC (CCL22). Each antibody pair was selected for sensitivity, specificity, accuracy and reproducibility. Suitable for use on various flow cytometers, the assays have higher sensitivity and wider dynamic range than typical ELISA methods. Further advantages include small sample volume requirement, flexible assay configurations and time- and cost-effectiveness. In addition, the assays have been validated with expected changes in relevant biological samples. The chemokine panels can be used for serum, plasma, cell culture supernatant, and other sample types, offering useful tools for biomedical research and drug discovery.

The initial fracture of composite materials is the micro-fractures. It is known that the final fracture of materials is caused by the accumulation of the micro-fractures. Fig.1 shows schematic drawing of the micro-fractures. The micro-fractures of fiber-reinforced composite materials are fiber rupture [1], resin crack, transverse crack, fracture between fiber and resin, and delamination between layers etc.


In this paper we present a typed natural deduction calculus to analyze the formal design of probabilistic computational processes, e.g. in use in machine learning techniques, to model their trustworthiness as a safety property.


Albeit there is a general consensus that urban design in the twentieth century failed in relation to space use, systematic research on this aspect has been very limited or at most inadequate in the developing countries. This study focuses on the above failure of urban design in this century with specific reference to the developing countries through an analysis of Dar es Salaam city centre, Tanzania. The modern city centre was analyzed critically through observation, document review, analysis of maps and plans, coupled with interview. The aim is to add to the understanding about: why and how urban design in this century failed with respect to space use in the developing countries, and how urban design in these countries could be made more successful in this respect. The results of the study suggest that dissociation of urban design in this century from prevailing economic, technological, and climatic conditions in the developing countries has been the overriding factor for its poor performance with respect to space use in these countries. The results show that because urban design in this century detached itself from prevailing economic, technological, and climatic conditions in the developing countries, it lead to urban spatial forms which are deterrent to meaningful space use. The results also provide important clues about how urban design in the developing countries could be improved with respect to space use within their existing economic, technological, and climatic circumstances. Particularly, the study reveals that through mixed land use patterns, traffic circulation systems which give less priority to vehicular traffic, less emphasis on urban solids, reconsideration of plot ratios, and more appropriate urban space treatment, urban design in the developing countries could be more successful in relation to space use.

The focus of this paper is on Ahlfors Q -regular compact sets E ⊂ R n such that, for each Q − 2 < α ≤ 0, the weighted measure μ α given by integrating the density ω( x ) = dist ( x , E ) α yields a Muckenhoupt A p -weight in a ball B containing E . For such sets E we show the existence of a bounded linear trace operator acting from W 1 , p ( B , μ α ) to B θ p , p ( E , H Q | E ) when 0 < θ < 1 − α + n − Q p , and the existence of a bounded linear extension operator from B θ p , p ( E , H Q | E ) to W 1 , p ( B , μ α ) when 1 − α + n − Q p ≤ θ < 1. We illustrate these results with E as the Sierpi´nski carpet, the Sierpi´nski gasket, and the von Koch snowflake.


Economic models based on simple rules can result in complex and unpredictable deterministic dynamics with emergent features similar to those of actual economies. I present several such models ranging from cellular automaton and register machines to quantum computation. The additional benefit of such models is displayed by extending them to model political entanglement to determine the impact of allowing majority redistributive voting. In general, the insights obtained from simulating the computations of simple rules can serve as an additional way to study economics, complementing equilibrium, literary, experimental, and empirical approaches. I culminate by presenting a minimal model of economic complexity that generates complex economic growth and diminishing poverty without any parameter fitting, and which, when modified to incorporate political entanglement, generates volatile stagnation and greater poverty.

Aluminum is one of the most versatile materials used in foundry practice; however, iron is one of the most troublesome impurities in aluminum cast materials. During the solidification of aluminum alloys, iron promotes the formation of intermediate phases, which may damage the properties of the final product. In secondary aluminum industries, iron contamination caused by high amounts of iron scrap is always possible. Consequently, the aim of this work was to study the most efficacious method and conditions for the removal of iron from molten aluminum through ceramic filters. The materials studied were based on the AA308 and AA356 aluminum alloys with iron additions. The variables of this work were chemical composition, temperature and the type of filter. The results showed that iron could be efficiently removed through the use of manganese and silicon followed by the decrease of the temperature at which the intermediate phases crystallize.

In these lectures we review how the symmetries of gravitational theories may be regarded as originating from those of "Yang-Mills squared". We begin by motivating the idea that certain aspects of gravitational theories can be captured by the product, in some sense, of two distinct Yang-Mills theories, particularly in the context of scattering amplitudes. We then introduce a concrete dictionary for the covariant fields of (super)gravity in terms of the product of two (super) Yang-Mills theories. The dictionary implies that the symmetries of each (super) Yang-Mills factor generate the symmetries of the corresponding (super)gravity theory: general covariance, p-form gauge invariance, local Lorentz invariance, local supersymmetry, Rsymmetry and U-duality.

In 1943, Bonner, Tatum, and Beadle (1) found that the isoleucinevaline-requiring mutant strain of Neurospora C~CLSSU (No. 16117) could use the oc-keto acids in place of the respective amino acids for growth. These results were obtained with keto acids prepared by the enzymatic oxidation of the corresponding amino acids; crude preparations were used for the nutrition experiments. In 1946, Bonner (2) repeated the experiments, using synthetically prepared keto acids. A competitive inhibition between these compounds was reported, as well as the observation that strain 16117 was unable to utilize synthetic oc-keto$-methyl-n-valeric acid for growth, although it was able to use synthetic ac-ketoisovaleric acid.1 This was in direct contrast with the results previously obtained with enzymatically prepared keto acids. At least two other reports have been published in which experiments involving "ketoisoleucine" have been described. In one of these, Tatum (3) reported experiments showing that the inhibition of wild type Escherichia coli by valine could be reversed by isoleucine but not by the keto acid and that certain mutant strains of bacteria were capable of using the dihydroxy acid (n,P-dihydroxy-fl-ethylbutyric acid) but not the keto acid in place of isoleucine. In another publication (4) Teas reported on growth experiments in which various isoleucine-requiring mutants were tested for their ability to use the ket.0 acid and other possible precursors in place of isoleucine. Many strains were found which were able to use 4-carbon

This essay deals with Lee Seung Hee's national movement. He was born in 1847 in the Confucian scholar family. He took methodical study about Confucianism that led him to the national movement. Also his movement was based upon the theory of Anti-Western Culture. The national movement was developed to make public appeals for Anti-Japan, presented a public appeals about Anti-Western culture, the campaign for a national debt redemption, and developed private diplomacy struggle until his asylum. His national movement was developed to set wholesome Confucianism atmosphere in Korea for popular stability, and to keep the sovereignty by diplomacy struggle. Lee Seung Hee sought asylum to Russia in 1907 after Emperor Gojong was abdicated by Imperialistic Japan. He met Lee Sang Sul who was a secret envoy for the Hague convention in Vladivostok. They discussed method of the national movement. Lee Seung Hee thought method of the national movement and built national movement bases in overseas country by Anti-Western culture. His purpose was the reconstruction of the Korean empire government. He moved to Andong and continued the national movement with the Beijing general Kongjiaohui. He thought the Beijing general Kongjiaohui united as an ideological and political pivot for Koreans in China. But He didn't totally accepted K'ang Yu-Wei's Grand-Unity. Because it had many differences with orgin-Confucianism. Also Lee Seung Hee wanted to develop center of the Beijing general Kongjiaohui in Andong with origin-Confucianism. Lee Seung Hee's national movement was finished by his death in 1916. However his national movement was continued by Confucian scholars in Sungju whom he had contacted during his asylum. And they developed his national movement to the 3.1 independence movement in 1919 and the independence declaration movement in the Versailles Peace Conference.


Odontogenic keratocystic tumors (KCOT) are found over a wide range of age and are associated with syndromes when found in younger age and in multiple number. Only 5 % are non-syndromic cases. We are reporting a case of non-syndromic multiple KCOT in 58 year old patient.


There are numerous conflicting epidemiological studies addressing correlations between cytochrome P450 1A1 (CYP1A1) genetic polymorphisms and lung cancer susceptibility, with associations plausibly linked to alterations in carcinogen bioactivation. Similarly, correlations between aryl hydrocarbon receptor gene ( AHR ) codon 554 genotype and CYP1A1 inducibility are controversial. The objective of this study was to determine whether smoking status, and CYP1A1 , AHR , and glutathione S -transferase M1 gene ( GSTM1 ) polymorphisms correlate with altered CYP1A1 activities. Lung microsomal CYP1A1-catalyzed 7-ethoxyresorufin O -dealkylation (EROD) activities were much higher in tissues from current smokers ( n = 46) than in those from non-/former smokers ( n = 24; 12.11 ± 13.46 and 0.77 ± 1.74 pmol/min/mg protein, respectively, mean ± SD; P 0.05). Three current smokers were heterozygous variant CYP1A1*1/2B (possessing both *2A and *2C alleles), and exhibited activities similar to individuals CYP1A*1/1 . One current smoker was heterozygous variant CYP1A1*4 and exhibited activities comparable with individuals CYP1A1*1/1 at that locus. EROD activities in microsomes from current smokers AHR 554 Arg/Arg ( n = 41) and heterozygous variant AHR 554 Arg/Lys ( n = 5) were not significantly different (12.13 ± 13.56 and 12.01 ± 14.23 pmol/min/mg protein, respectively; P > 0.05). Furthermore, microsomal EROD activities from current smokers with the GSTM1 -null genotype ( n = 28) were not significantly different from those ( n = 18) carrying at least one copy of GSTM1 (12.61 ± 14.24 and 11.34 ± 12.53 pmol/min/mg protein, respectively; P > 0.05). Additionally, when genotypic combinations of CYP1A1 , AHR , and GSTM1 were assessed, there were no significant effects on EROD activity. On the basis of microsomal enzyme activities from heterozygotes, CYP1A1*1/2A , CYP1A1*1/2B , CYP1A1*1/4 , and AHR 554 Arg/Lys variants do not appear to significantly affect CYP1A1 activities in human lung, and we observed no association between CYP1A1 activity and the GSTM1 -null polymorphism.


This study aims to determine students scientific literacy skills after learning with a contextual-flipped classroom model. In flipped classroom-contextual learning, students study the lesson material through contextual videos outside the classroom, then conduct discussions in class and lab work. This study used a qualitative method with 36 students in class XI at senior high school in Jakarta. Data collection were carried out through scientific literacy tests, observation, interviews, and reflective journal of students. The students' scientific literacy skills in this study refer to the scientific literacy of PISA. The results showed that 16.7% students had achieved scientific literacy at level 6; 38.9% at level 5; 11.1% at level 4; 27.8% at level 3; 5.6% at level 2 and 1. In addition, the results of the study show that aspects of scientific literacy have also been mastered by students. Mastery of scientific literacy aspects, concerning: aspect of the scientific context is 83.92%, aspect of science knowledge is 84.36%, and aspect of scientific competence is 84.06%. Thus, it can be concluded that acid-base learning with a contextual-flipped classroom model can improve students scientific literacy skills.

Law enforcement officers (LEOs) are often called upon to perform physically demanding tasks as part of their normal job duties. Physical ability tests (PATs) are frequently used by employers within physically demanding occupations to determine an individual's ability to perform essential occupational tasks. Trainees and qualified officers need to understand the physical fitness demands associated with successful performance in each component in order to be physically prepared to perform PATs and related occupational tasks. PURPOSE: The purpose of this study was to determine whether significant differences existed between high, average, and low performers on an occupationally specific PAT based on fitness, sex, and anthropometric characteristics among state patrol officers. METHODS: A retrospective analysis was conducted of 275 LEOs (age = 38.0 ± 7.6 yr; females, n = 19; males, n = 256; body mass = 91.1 ± 15.0 kg). Physical fitness measures, included: body fat % (BF), vertical jump (VJ), sit-and-reach test (SR), 1-minute sit-up (SU), 1-minute push-up (PU), and 2.4 km run time (2.4R). The PAT consisted of several tasks, such as a simulated pursuit, victim drag, vehicle push, traversing an embankment, low crawl, and barrier jump. A principal component analysis was utilized to determine differences in performance between high, moderate and low performers on the PAT. Where possible, the data were also analyzed by sex. RESULTS: The statistical analysis revealed that lower dynamic fitness and BF explained 50% of the variance in PAT performance between groups, with flexibility explaining an additional 15% of the variance. PAT performance was also predicted by 2.4R in both sexes, and by 2.4R, SR, SU, and age in men. CONCLUSION: Physical fitness relates to several occupational demands in law enforcement. When designing programs to assist LEO with improving their performance on PAT and occupational tasks, strength and conditioning professionals should focus on developing aerobic capacity, trunk muscular endurance, and whole-body anaerobic power. Introduction Methods Physical ability tests (PATs) are frequently used by organizations with physically demanding occupations to determine the level of an individual's ability to perform essential occupational tasks (Arvey et al. 1992; Stanish, 1996; Dawes et al., 2015; Dawes et al., 2017). Many agencies have developed their own PATs to evaluate job performance of sworn officers. Understanding the physical fitness components associated with successful performance in each component is vital if trainees and qualified officers are to be physically prepared to perform these PATs and the related occupational tasks. Although several studies have investigated the relationship between physical fitness and PAT performance among LEOs (Stanish, 1996; Dawes et al., 2015; Dawes et al., 2017), differences in the physical fitness and anthropometric characteristics between high, average and low performers by sex in a PAT has not been specifically investigated in LEO. Therefore, the purpose of this study was to determine whether significant differences existed between high, average, and low performers on an occupationally specific PAT based on fitness, sex, and anthropometric characteristics among patrol officers.

Forty un-vaccinated dogs were immunized with rabies virus glycoprotein/nucleoprotein bivalent DNA vaccine pVGN for 3 times, and the biosafety was evaluated by means of the observation on the development of immune responses in the immunized dogs, monitoring the transference of the kanamycin-resistance gene, detection of the distributions of plasmid in the main organs and the injected tissues; observations of the pathological changes in the main organs as well as analysis of the influences of vaccine on the pregnant dogs and their puppies. The result showed that this DNA vaccine could induce excellent humoral immune responses in the immunized dogs without any abnormal clinical responses observed. Transference of the kanamycin-resistance gene in the DNA vaccine to the normal intestinal flora did not occur, and this gene was also not excreted into surroundings through intestinal flora, urine and saliva. The plasmid could be detected in heart, kidney and the injected tissues, and persisted in these area for 18, 14~18, 14 and 26 weeks respectively, while it could not be detected in liver. No integration of the plasmid DNA with the genomic DNA in the above-mentioned area was found. Also, there were no histopathological changes observed in the main organs. The vaccine had no influence on the pregnant dogs and their puppies. It indicates that this bivalent DNA vaccine not only possess the satisfied immunogenicity, but also has no problem on biosafety.


The aim of the thesis consist on the process simulation and techno-economic analysis of two processes to produce Jet fuel from a renewable waste cooking oil feedstock: Hydroprocessed Renewable (HRJ) from the UOP/ENI EconingTM technology, which have been recently commercialized, and Catalytic Transfer Hydrogenation(CTH), in stage of research.


GIS-based approaches for the optimal expansion of renewable energies are characterized by a strong dominance of engineering-oriented perspectives. It is acknowledged that it can be beneficial for the acceptance, to combine techno-economic site analysis with social perspectives. However, this only succeeds superficially, because essential theoretical perceptions from social and economic sciences are often neglected and the integration of social parameters is degraded to trivial attempts of approach. This fundamental criticism of a techno-economic oriented and target deterministic energy planning by GIS are carried out in the framework of the study. Build on this, more complex approaches for the integration of social perspectives in GIS-planning tools are exemplified.


Cancer patients may suffer from a plethora of symptoms at all stages of their disease. Pain is one of the most feared and distressing symptoms experienced by people with cancer and may be the dominating symptom at time of diagnosis of cancer, a sign of disease relapse, a symptom of late toxicity and a key symptom in patients with advanced cancer. Pain is often associated with depression and impaired quality of life, consistent with a biopsychosocial model. The main goal of this study is to investigate the relation among pain, anxiety and depression in a population of oncological patients and the secondary objective is to analyse the association between cancer pain and coping styles.


The classical method of solving electromagnetic field problems involving boundary perturbations is reformulated in a way that is both more general and simpler. The new formulation makes it easier to apply the theory to the class of boundaries amenable to the classical formulation, and shows that it can also be applied to other boundary shapes. As an example, the perfectly conducting sphere with surface perturbations has been treated, using the methods appropriate only for boundaries in the classical class and also using those applicable to the larger class. Some experimental results which appear to support the theory are reported.


Climate change, the growing worldwide population, and the extensive ecological footprint of the agriculture and agri‐food industries are urging food science researchers to address some of humanity's most pressing concerns. Current research programmes focus on enhancement of food processing efficiency and optimal use of crops and plant proteins to reduce non‐sustainable use of animal proteins. These practices often come at a penalty for taste and texture, which is prompting the industry to redesign many existing food formulation and processing routes. These developments have led to a renewed interest in relations between food composition, structure, and consumer appreciation. This special issue of MRC presents recent examples of the pivotal enabling role of NMR and MRI techniques in food science to understand the functionality of foods, their processing, their stability, and their impact on health and sensorial perception. Several papers describe how liquid state NMR has continued to develop itself as a tool for molecular identification and quantification. NMR‐based metabolomics continues to play a critical role in food authentication and we are now observing focused applications in the assessment of the impact of processing on food quality. This special issue also reports on the progress of using NMR and MRI on quantitative assessment of food structure. This is an area where NMR relaxometric and diffusometric applications are represented by 13 papers. The deployment of even more sophisticated pulse sequences as well as more advanced signal processing approaches now enables the estimation of quantitative descriptors of food structure. Three papers in this issue show how the use of MRI has become mainstream for


With the two-photon absorption enhanced by the internal Fabry-Perot resonator, a 2-µm wavelength 250 MHz sinusoidally-modulated optical signal is detected by a commercial 1.55-µm multi-quantum well laser diode with the photocurrent up to 20.59 µA.


Round robin for development of standardised tribology test-methods. To develop accepted friction and wear test methods for hard thin coatings an international round robin test with 27 participating laboratories from twelve countries was performed. A German round robin with twelve participants was startet for fretting wear of thin coatings. A compilation and first valuation of the reported results for titanium nitride coatings reveals the still existing difficulties and limits of reproductibility of such tests. Although all participants got identical test samples and performed the tests according to an identical test procedure the scattering of the reported friction and wear values were great as well for the test repetitions of the same laboratory as between the mean values for the different laboratories


ABSTRACT Taking into account the image and narrative analysis akin to film studies, as well as discourse as per the long-standing tradition of print analysis, this article suggests a dedicated triadic multimodal methodological approach for television news analysis. The precise methodology for best practice qualitative text analysis is as yet poorly defined (Macnamara 2005, 16), but this article proposes a solution to that very concern. This article engages with the methodological challenges of studying television news, and critically reviews several established methods – semiotics, discourse analysis, and the context of media production – but calls for a more holistic approach that better integrates the multimodal nature of television news. I propose a method which allows a blend of the different tracks of television news, from audio and visual to the political economy of these texts. I do so with a view to providing tools for media and journalism students to carry out a beginner's analysis, but also for more established research to engage with the requirements of studying television news. I then provide an example of how this triadic method can be operationalised by analysing a television news broadcast in relation to the coverage of violence in the context of the 2014 South African election.


Zone of tolerance (ZOT) represents the acceptance range of service quality having bipolar extremities in the form of desired and accepted levels. ZOT is particularly critical in service transactions as they are heterogeneous and intangible and presumed to be mediating service quality and behavioural intention link. Customer relationship management (CRM) has emerged as a pivotal business process which has nullified, to a large extent, the probability of service defection, thereby, enabling the service providers to stretch the bandwidth of ZOT of individual customer. This paper empirically tests the intervening effects of ZOT on automated banking service quality and its behavioural intentions with a novel approach of generating CRM index and examining its effects on modifying ZOT. Structural equation modeling was used to validate the nomological link between the variables. Both exploratory and confirmatory analyses were used to assess the measurement properties and bivariate correlation and regression analysis were used to test the hypotheses. E‐ SERVQUAL (Parasuraman, Zeithaml & Malhotra, 2005) and behavioural intention battery (Zeithaml, Berry & Parasuraman, 1996) were used for the study with adequate modifications.


PurposeThe purpose of this study is to analyze year-end spending practices in the European Economic Area (EEA) to baseline the pervasiveness of year-end spending spikes across countries in Europe.Design/methodology/approachThe Tenders Electronic Daily dataset is used to descriptively analyze above-threshold procurement contracts by country, year and contract type from 2009 to 2018. Proportional distributions are employed to compare percentages of spend across quarters. Analyses are run within each country on the number of years displaying a fourth quarter spike, as well as within each country and contract type.FindingsThe results show that while spending spikes for above-threshold contracts in the final fiscal quarter are not consistent across all countries, patterns emerge when the data are disaggregated by country. The most populous nations in the EEA are more likely to have years with the highest proportion of fiscal spend occurring in the fourth quarter. Further, the type of contract makes a difference – services and supplies contracts are more likely to display fourth quarter spikes than works contracts.Originality/valueThis article provides the first analysis of the year-end spending spike across countries in Europe using procurement data, as well as the first to disaggregate by year and contract type. Findings support the literature on the presence of year-end spikes; such spikes exist even for above-threshold public procurement contracts.


Summary form only given. We report on experiments conducted to investigate the thermal interruption capability of high voltage self-blast gas circuit breakers. In parallel, the circuit breaker behavior is studied using computational fluid dynamics tools. It is well-known that nozzle ablation leads to systematic performance degradation. The influence of nozzle ablation on various parameters is studied as a function of the number of interruptions. Overall thermal interruption features of a test series are presented along with an analysis of the synthetic circuit. In order to study fluctuation characteristics during thermal interruption, we apply spectral analysis to our measurements of pressure in the accessible volumes of the circuit breaker, e.g. in the heating volume. We have identified pressure turbulence at frequencies above 100 kHz during the high pressure phase. A search for systematical dependencies of the fluctuations on nozzle ablation is presented. Additionally, fluctuations in the current and voltage measurements are touched upon


Modern multi-object tracking (MOT) benefited from recent advances in deep neural network and large video datasets. However, there are still some challenges impeding further improvement of the tracking performance, including complex background, fast motion and occlusion scenes. In this paper, we propose a new framework which employs motion information with optical flow, enable directly distinguishing the foreground and background regions. The proposed end-to-end network consists of two branches to separately model the spatial feature representations and optical flow motion patterns. We propose different fusion mechanism by combining the motion clues and appearance information. The results on MOT17 dataset show that our method is an effective mechanism in modeling temporal-spatial information.


ABSTRACT With respect to urban development a common practice is to exclude flood-prone areas from further construction for flood safety reasons. Granting exemptions when local flood safety measures are applied is a topic of continued debate. The Ottnager-Redl/Upper Austria case study investigates various future settlement scenarios with or without local flood protection measures (LFPM). In accordance with the legal situation in the Federal Province of Upper Austria, construction permits require flood safety up to a 100-year flood level plus 20 cm. Estimations of potential flood damage in the catchment's residential areas are based on damage functions used to describe the structural vulnerability at an object level. Impacts are simulated with a distributed hydrological and a 2D-hydraulic model, which incorporate future settlement dynamics. In addition to linking losses to return periods, the cumulative damages within design periods are estimated using a Monte-Carlo modelling framework. Event-based and cumulative losses increase with the different settlement scenarios. The LFPM tested visibly reduce the cumulative losses as they are triggered by high-frequency/low-impact events. Considering single events, the positive effects of LFPM, specifically flexible flood barriers, generally vanish when they exceed the design level. Thus, the increased flood risk due to intensified settlement in the flood-prone area cannot be compensated by LFPM.

Introduction: The Pierre Robin Sequence (PRS), is classified as part of congenital malformation syndromes that mainly affect facial appearance which varies according to the severity of the individual clinical case. To guarantee the fulfillment of an optimal protocol the treatment of these patients must be interdisciplinary. Objective: identify the different techniques applied to treat PRS, following treatment guidelines according to the severity of each specific case. Methods: Systemic study of available literature using scoping review as an exploratory mean. Databases used were as follows: PubMed, Scielo, Google Scholar, Wiley Online Library and Sematic Scholar. Results: 58 articles were included in this study which complied with inclusion and exclusion criteria. According to 40 of such articles, 53.73% of cases were treated with Mandibular Osteogenic Distraction; making this technique the most used amongst the authors. The remaining 18 articles showed other techniques such as prone positioning and nasopharyngeal intubation. Conclusions: According to the present literature, techniques to treat PRS vary and should be used according to the patient's systemic condition. The level of severity of each case is considered of great importance in decision making when determining which technique to apply considering the PRS triad or any of the different present characteristics.

This is the first book that deals with practical stability and its development. It presents a systematic study of the theory of practical stability in terms of two different measures and arbitrary sets and demonstrates the manifestations of general Lyapunov's method by showing how this effective technique can be adapted to investigate various apparently diverse nonlinear problems including control systems and multivalued differential equations.


The planetary scan system was designed and developed to support the planetary encounter activities of the Mariner Mars 1964 mission. Its primary functions are to search for, acquire and track the planet Mars in order to orient the television camera properly during the period immediately preceding the TV picture-recording sequence. This Report describes the design, development, fabrication, testing and performance of the system. The system was designed to scan an instrument platform 180 deg in the process of searching for the planet. The scanning provides motion in one direction while the moving spacecraft on its trajectory provides motion approximately perpendicular to the scanning plane. Limit switch action produces signals to reverse the scan direction at the end of each 180-deg sweep. Planet acquisition and tracking are accomplished by a radiation detector with optics having a 50-deg circular field of view. This detector is used to detect the presence of the planet and to sense the position of the planet relative to the spacecraft, When the planet comes into the detector's field of view, the system switches to planet-tracking operation and proceeds such that the desired portion of the planet is used as the nulling plane for the servo system. A 4OO-cps motor is used for the searching and tracking. To indicate that the planet has been acquired, a planet-in-view signal is generated and telemetered to Earth in real time. This signal is also used to switch the spacecraft data mode to planet encounter format. Upon receiving a scan inhibit signal from the spacecraft, the scanning and tracking motion of the system ceases. The Mariner N spacecraft was successfully launched from Launch Complex 12, Air Force Eastern Test Range at Cape Kennedy, Florida, on November 5,1964. The planetary scan system in this spacecraft was energized three times throughout the fight. It was energized the first time on February 12, 1965, during the early science cover drop sequence, the second time during the 9-hr planet encounter period on July 14, 1965, and the third time during the television dark encounter (calibration) sequence on August 30, 1965. The system operated properly in each of the sequences. The system flight performances in each of these sequences are also included in this Report. I JPL TECHNICAL REPORT NO. 32-919

In April 1967 one of the most outstanding Soviet scholars, Akademician Il'ya Nestorovich Vekua, Laureate of the Lenin and State prizes, author of about 100 scientific papers on mathematics and mechanics, founder and head of numerous schools of Soviet mathematicians working in the field of partial differential equations and their applications celebrated his sixtieth birthday, Il'ya Nestorovich Vekua was born into the peasant family of Nestor Pedorovich Vekua on April, 23rd 1907 in the Georgian village of Shesheleta. Vekua' s dream of education and possibly also of scientific service, a dream which was especially nurtured during his youth by his grandfather, began to be fulfilled during Soviet times. In 1930, he graduated in the Faculty of Physico-Mathematics at the Tiflis State University; and this marked his first steps into science. In the same year. Vekua entered the post-graduate school of the USSR Academy of Sciences in Leningrad, where he successfully completed his course after three years. His return to Georgia in 1933 was the beginning of a twenty year period of vigorous scientific, pedagogical and public activity. By dint of a number of outstanding articles in pure and applied mathematics Vekua very soon became one of the leading representatives of the Tiflis mathematics school. The Tiflis Mathematical Institute of the Academy of Sciences of the Georgian SSR was founded with the help of Vekua' s active participation. In 1939 Vekua defended his doctoral dissertation, and one year later was appointed to the rank of Professor. In 1944 he was elected Corresponding Member of the Georgian SSR Academy of Sciences; and in 1946 he was elected Member of that Academy and Corresponding Member of the Academy of Sciences of the USSR. In 1953 Vekua,' s creative activity found further stimulation at the Steklov Mathematical Institute in Moscow; he worked at the Institute as Deputy Director until 1958; Vekua was then elected Member of the Academy of Sciences of the USSR and along with a group of major Soviet scholars moved to Novosibirsk.


Human gut is associated with trillions of bacteria, ten times higher than the number of the cells in the mammalian body. So the microbiota can be considered as a separate organ. Their presence seems inert in the case of commensals or has beneficial roles in symbionts. In certain circumstances when the gut barrier is disrupted, the gut microbiota can generate immune responses detrimental to the human host. Besides that, irregular distribution of commensal bacteria is linked with the metabolic disorder, obesity, inflammatory bowel disease and cancer [1]. The underlying mechanism of host-gut microbe interactions are still not clear and better knowledge will help to prevent diseases and in the generation of targeted therapy. The impact of the gut microbiota is not only limited to the mucosal surface but it also regulates distant organ sites by promoting innate immune cell development by hematopoiesis. Disruption of the gut microbiota or dysbiosis can lead to gastric ulcers, nonalcoholic fatty liver disease, obesity, metabolic syndromes and hypertension; inflammatory bowel disease, colon cancer, mood and behavioral changes through hormone signaling. The gut microbiota also controls the colonization of pathogenic microbes. The role of gut microbiota and host interactions in metabolic and cardiovascular diseases will be highlighted in this editorial. The link between gut flora and the development of obesity is well established. In genetically obese mice or in obese human volunteers, a significant alteration in Bacteroidetes and Firmicutes was observed compared to lean controls [2]. The microbial production of short-chain fatty acids (SCFA), trimethylamine, acetaldehyde and inflammatory mediators has been shown to significantly impact the metabolic health of the host through pathways that influence satiety, gut permeability and immune function. N-butyrate generated from SCFA regulates leptin production in adipocytes and also controls antiinflammatory responses by reducing cytokine-chemokine release by immune cells. So, targeting butyrate and butyrate producing gut-bacteria can be a new way of restoring host immune function and regulation of energy metabolism [3]. Cardiovascular disease (CVD) is widely recognized as an inflammatory disease. Chronic inflammation is an independent risk factor for atherosclerosis by promoting plaque formation and inducing endothelial dysfunction. Coronary heart disease (CHD) occurs significantly more frequently in patients with inflammatory bowel disease (IBD). However, there is an ongoing debate whether heart disease is linked to viral or bacterial infection. A 13-year study period with 272 adults with nontyphoidal Salmonella NTS bacteremia showed 35% of the patients have extra-intestinal focal infections; 15% developed mycotic aneurysm exclusively after age 45 years, and the rates of mycotic aneurysm (bacterial infection of the arterial wall) increased with the age of patients with NTS bacteremia.


This period that has abruptly slowed down our confined lives during the acute phase of the pandemic could be an incubation period for change, and it could also accelerate our transition into a new phase of the world capitalist system. The dangers and opportunities that we are living during a paradoxical phase of history increase anxiety and fear, which is being experienced with the constant uncertainty of science and politics with horizons of meaning that are insufficient. At the same time, various options have become clear and almost compulsory. It's as if all of us, or almost all of us, had the certainty that we had to stop, contain, change, or stop doing a variety of things that we had never taken into consideration. Others stopped making sense and we understand that the system in which we live is extremely fragile and offers little protection. Nonetheless, political power gains a new centrality, by placing almost all of us in social confinement and paralyzing the economy to its almost entirety. We are in a time of apparent disorder, great uncertainty and risk and it becomes important for us here to question and understand these meanings in order to anticipate the effects and consequences, but also to project the social changes that may build a better and more equitable world.


Tobacco use is the greatest preventable cause of cancer in the United States, accounting for almost one third of all cancerrelated deaths and 90% of deaths from lung cancer. Despite widespread knowledge of these risks, tobacco use prevalence rates are 20% in the United States and up to 30% to 50% in the developing world (1, 2). Nicotine, the addictive chemical in tobacco, produces a biological dependence (3), and therefore, even with the most efficacious medications available, only one in four smokers is able to maintain long-term abstinence (4). Persistent tobacco use is common even following a diagnosis of tobaccorelated cancer and is associated with poorer outcomes of radiation therapy and chemotherapy and with increased risk of second primary malignancies (5). Although smoking cessation is optimal, it may not be realistic for all patients. Therefore, it is essential to gain a better understanding of the cellular and molecular mechanisms through which tobacco exposure contributes to cancer pathogenesis and outcomes, and to develop targeted prevention and therapeutic approaches. Toward this end, a study reported by Gumus et al. (6) in this issue of the journal characterized gene expression profiles in the oral mucosa of smokers and nonsmokers and validated their findings by examining the in vitro effects of tobacco smoke condensate on gene expression in an oral leukoplakia cell line. Another related study also reported in this issue of the journal was conducted by Zhang et al. (7), who compared gene expression in cells obtained from bronchial brushes from never, current, and former smokers. Smoking effects on global gene expression were common across these studies. Certain genes (CYP1A1 and CYP1B1) that were up-regulated in buccal oral specimens of smokers were part of a larger group (CYP1A1, CYP1B1, ALDH3A1, NQO1, and AKR1C1) up-regulated following in vitro exposure to tobacco smoke condensate (6) and in the airway cells of smokers (7). Zhang and colleagues provide further in vivo evidence that many of these genes are down-regulated in persons who reported quitting smoking at least 1 year before the assessment (CYP1B1, AKR1C1, AKR1C2, AKR1B10 ,a ndALDH3A1). Many of these same genes were previously shown to be overexpressed in oral cancer cells exposed to tobacco smoke condensate (8), in bronchial epithelial cells of smokers, and in patients' non–small cell lung carcinoma cells (9, 10). The effects are also consistent with the effects of smoking on the airway transcriptome (11, 12). Taken together, these findings identify important tobacco smoke exposure response genes. The studies of Gumus et al. and Zhang et al. in this issue of the journal provide an elegant illustration of the value of cross-model (preclinical and clinical) validation in translational cancer prevention research.

We report a novel catalyst Pd/SOS that catalyzes the dual C–C bond forming coupling of an iodoarene moiety with an internal alkene and an external alkyne via an intramolecular Heck reaction, followed by an intermolecular Sonogashira reaction, respectively. The catalyst was characterized using XRD, IR, XPS, SEM and TEM analyses. Notably, for the first time, cheap and readily available new silica [nanosilica on microsilica (SOS)] material-supported ultra-small Pd nanoparticles (2.20 nm) are employed for the efficient synthesis of dihydrobenzofuran and oxindole derivatives in a domino one-pot reaction. Significantly, a sub-molar quantity of Pd (0.3 mol%) was found to be sufficient to furnish the products in very good to near quantitative yields. Gratifyingly, the catalyst could be recycled up to five cycles with a marginal loss (∼no loss) of the product.


but no spirits. The liver reached considerably below the costal margin, and at the operation Mr. Compton found its surface rough and coarsely granulated; the spleen also had a rough surface and was somewhat enlarged at the operation, though by ordinary palpation before the operation it could not be felt. The Wassermann reaction was negative. The blood-serum showed slight excess of " blood-bilirubin." The galactose test indicated some impairment of hepatic function. The operation was carried out on September 6, 1927, and this time, with the object of avoiding a subsequent hernia, Mr. Compton inserted a portion of the omentum within the sheath of. the right rectus abdominis muscle, behind the muscle substance (Mayo's method). The surface of the liver was rubbed at the time of the operation. Paracentesis abdominis has not been needed since the operation, and possibly will not be needed again. Ascites, if present at all, is exceedingly slight. It must be noted, however, that hardly any ascitic fluid had re-accumulated between the time of the first (and only) tapping and the omentopexy, and this may have indicated a spontaneous tendency to cure.

Business growth is one of the business phenomena that is an object of study with a large quantity or analytic approaches and decision environments. This paper studies the internationalization strategy, transformed into one of the key growth vectors more frequently used by the companies in this ever more globalized environment. Growth, in general, and internationalization, more precisely, as a business phenomena with many shades requires research methods which are able to collect all their complexity. Our aim in this paper is to analyse an illustrative case of business group growth through internationalization. CIE Automotive is an example of using the strategic internationalization model as a theoretic model and methodology design to study the cases in the scientific research.


Flooding occurred across a large area of southern and central Queensland in December 2010 and January 2011. Intense rainfall over the Gowrie Creek catchment caused severe flash flooding through the Toowoomba CBD (Central Business District) on the afternoon of Monday, 10 January 2011, taking lives and damaging the community. Flash floods are sudden and unexpected floods that arise from intense rainfall, generally over a small, steep catchment area. Smaller and steeper catchments have shorter critical storm
duration, and they respond more quickly to rainfall events. The resulting flood wave is characterized by very high water flows and velocities and abrupt water level rises, leading to extremely hazardous conditions. Effective flash flood forecasting for specific locations is a big challenge because of the behaviour of intense thunderstorms. A flash flood forecasting and warning system calls for accurate spatial information on catchment characteristics. A high-resolution DEM is a key spatial dataset for the characterization of a catchment to design possible flood mitigation measures. The characteristics of a catchment have a strong influence on its hydrological response. The nature of floods is dependent on both the intensity and duration of the rainfall and the catchment characteristics such as catchment area, drainage patterns and waterway steepness. Therefore, analysis of catchment characteristics is critical for hydrologic modelling and planning for flood risk mitigation. The analysis of catchment characteristics can support hydrological modelling and planning for flood risk mitigation. For example, the shape indices of sub-catchments can be used to compare the hydrological behaviour of different subcatchments. The longitudinal profiles of the creeks illustrate the slope gradients of the waterways. A hypsometric curve for each sub-catchment provides an overall view of the slope of a catchment and is closely related to ground slope characteristics of a catchment. Airborne light detection and ranging (LiDAR), also referred to as airborne laser scanning (ALS), is one of the most effective means of terrain data collection.
Using LiDAR data for generation of DEMs is becoming a standard practice in the spatial science community. This study used airborne LiDAR data to generate a high-resolution DEM for characteristic analysis of Gowrie Creek catchment in Toowoomba, Queensland, Australia, which was affected by a flash flood in January 2011. Drainage networks and sub-catchment boundaries were extracted from LiDAR-derived DEM. Catchment characteristics including sub-catchment areas and shape indices, longitudinal profiles of creeks and hypsometric curves of sub-catchments were calculated and analysed.


Recently Cui et al. reported on the fabrication a p-n homojunction perovskite solar cell (PSC) using stoichiometric control of sequentially-deposited perovskite layers. The authors propose that the junction leads to an enhanced electric field in the perovskite absorber resulting in improved charge separation. In this response to Cui et al. 2019 we show that the experimental data presented in the paper does not directly support this claim. Furthermore, Cui et al.'s thesis is not compatible with the large body of existing literature showing that mobile ionic defects present in methyl-ammonium lead iodide (MAPI) and its derivatives are highly mobile at room temperature. Using drift diffusion device simulations we show that large densities of mobile ionic charge in the system are likely to the screen any beneficial effects of a p-n homojunction.

Compounds having a vinyldimethylsilyl group at both terminals have been successfully cyclized by ruthenium hydride catalysts to give selectively disilacycles of various ring sizes via a metathetical reaction, i.e. ethene elimination from the two terminal vinyl groups, not involving metallocarbene–metallacyclobutane type intermediates.


The general framework concerns embedding ICT into the physical process of distribution. Incidentally, information bottlenecks tend to correspond to transportation bottlenecks, ports being the most relevant example for freight. A port region is composed of thousands of players in interaction ranging from port authorities, terminal operators, maritime shipping companies, freight forwarders, trucking companies etc. Their transactions generate large quantities of information and since these transactions take place within a regional cluster, there is a propensity to better interconnect the regional transactional system and consequently improve the efficiency of the bottleneck. In many cases, more benefits can be realized through better synchronization of existing transport and distribution assets than through additional infrastructure.


We report on organic light-emitting transistors with a submicron-channel length, gold source, and calcium drain contacts. The respective contact metals allow efficient injection of holes and electrons in the tetracene channel material. Transistor characteristics were measured in parallel with electroluminescence being recorded by a digital camera focused on the transistor channel. In the case of submicron-channel lengths, the transistor source-drain current at higher gate voltages was determined by the source-drain voltage. At larger channel lengths, the source-drain current was limited by the injection of electrons from the calcium contact, as hole ejection to this contact was fully blocked. The hole blocking is explained in terms of a chemical reaction occurring at the Ca/tetracene interface.

A computerized micro-RIM machine has been designed and built for the study of Nylon 6 reaction injection molding (RIM). This machine was designed for three major purposes: interfacing with analytical instruments, molding of samples for mechanical testing, and precise control and monitoring of the RIM process. The machine is capable of injecting a wide range of amounts of material, between 0.04 and 200.0 cm in steps of 0.04 cm. The accuracy of injections is ±0.004 cm. The micro-RIM machine has been interfaced with a Fourier transform infrared spectrometer (FT-IR). Infrared spectra have been recorded at 0.33 second intervals during the RIM process. This provides the capability for following the fast polymerization and crystallization of Nylon 6 RIM in situ and isothermally. The machine has also been used to mold samples of nylon 6 and nylon 6 reinforced with silicon whiskers.


We reported a case of rheumatoid arthritis (RA) with asymmetrical manifestation of wrist arthropathy in a hemiplegic stroke patient. The patient was a 61-year-old woman who had a left thalamic hemorrhage and now suffered right hemiplegia. Six months after her apoplectic stroke she complained of left wrist pain. X-ray examination indicated that her left wrist joint was destroyed. The sparing effect was observed in her paralyzed right wrist. The test for serum rheumatoid factor was positive and the patient's inflammatory signs were elevated. Consequently, she was administered anti-rheumatic drugs and fitted with a left wrist orthosis and her left wrist pain diminished. We also discuss the mechanism of unilateral RA.


Low-spin excited states of 140Nd have been studied via the 140Ce(3He,3n)140Nd reaction. The results from the data analysis show that one of the candidates for the one-phonon mixed symmetry state of 140Nd, namely the 2+3 state at 2140 keV with an effective lifetime of 220(90) fs, decay with a fast M1 transition to the 2+1 state. Therefore consequently this state can be treated as, at least a fragment of the one-phonon MSS of 140Nd. This is the first example where mixed symmetry character is tentatively assigned to a state of an unstable nucleus from the mass A ≈ 140 region based on the data on absolute M1 transition rates.


Harmonic spectra have been calculated by numerically integrating the one-dimensional Schrodinger equation for a model potential and a laser field sufficiently intense to cause significant or complete ionisation. The use of a one-dimensional model allows realistic pulse lengths (1 ps) and laser wavelengths (0.5 and 1 μm) to be considered. The dependence of the plateau cutoff on laser intensity has been studied in detail, from far below to far above the saturation intensity. We find that below saturation the cutoff scales approximately linearly with laser intensity, and that the cutoff continues to increase beyond saturation, although at a slower rate. At high intensities, where ionisation occurs rapidly during the leading edge of the laser pulse, the edge of the plateau becomes less clearly defined


Aim:  The use of interleukin‐2 receptor antibody (IL‐2Ra) induction has been associated with reduced rejection rates in renal transplant recipients. However, the effect of IL‐2Ra induction on graft and patient outcomes in renal transplant recipients with differing immunological risk remains unclear.


This paper focuses on the influence of party ideology on fiscal behavior in Brazilian states between 1986 and 2005. To carry out its objectives, the paper first builds up a new variable to measure party ideology of both the state Executive and Legislative. The paper, also considers the series of institutional changes, hardening budget constraints, which occurred during the period. Three results stand out. First, party ideology does influence fiscal behavior. Second, right wing governments showed better fiscal behavior, mostly by increasing revenues. Finally, institutional changes mediated the influence of party ideology over fiscal behavior: left wing government showed better fiscal results, mostly as a reaction to the debt restructuring process; similarly, left wing legislatives showed better fiscal results as a reaction the Fiscal Responsibility Law. The results were obtained with a Panel Corrected Standard Errors (PCSE).


In this work, the influence of velocity distribution phase correction on the acoustic impedance of a circular source located in an infinite baffle is analyzed. It has been observed that by turning back a velocity distribution phase by modifying the radiating surface shape in a special way, obtaining a more coherent acoustic radiation is possible. This problem has been analyzed during earlier investigations, with attention focused on the directivity of some acoustic sources [1]. The aim of this paper is to calculate the acoustic impedance which allows the examination of such a ``phase correction'' effect on the acoustic radiation of the considered sound sources. The result was achieved by numerical calculation with the use of Hankel representation of the acoustic impedance.


This paper describes an integrated system of secondary metallurgy (ISSM), which is exploited at the company EVRAZ Vítkovice Steel a.s. Ostrava Czech Republic. The system consists of a caisson-type vacuum unit, enabling chemical boosting, decarburisation, desulphurisation, chemical homogenisation and the modification of a liquid steel's chemical composition simultaneously in two ladles. The experimental part was focused on observation and evaluation with a statistical analysis of the parameters, which influence substantially the final hydrogen content after a vacuum treatment of steel. The most important of the monitored parameters appeared to be the vacuum treatment time, the sulphur content in the refined steel and the difference between initial and final temperatures of the steel in the ISSM.


Cross sections for jet and lepton-pair production at large transverse momenta are studied in a class of renormalizable field theories including quantum chromodynamics. To all orders in perturbation theory, appropriate moments are seen to factorize short-distance from long-distance dependence in leptoproduction. Scale breaking is governed by the anomalous dimensions of twist-two operators. These results are extended to hadron-hadron scattering for theories where infrared divergences cancel in the sum over soft particle emissions, even in the limit that all particle masses vanish. This cancellation is explicitly demonstrated for totally massless QED.
