Understanding of the impact of kinetic and transport coupling on the combustion characteristics for alkane and aromatics blended fuels is of great importance to construct a reliable surrogate fuel model for JP-8 fuels. The diffusion flame structures and extinction limits of n-decane/toluene/nitrogen mixtures were studied experimentally and computationally through the use of counterflow diffusion flames with nitrogen dilution. The impact of toluene addition to n-decane on the extinction limit, OH distribution, and maximum heat release were investigated. The results showed that as the toluene blending ratio was increased, the extinction strain rate decreased significantly. It was also found that the extinction limit depends linearly on the radical pool for the blended fuels. Planar laser induced fluorescence measurements of OH showed that the maximum concentration of OH found experimentally was more sensitive to toluene addition than found in numerical computations. The maximum chemical heat release rate showed that CO + OH → CO2 + H was one of the dominant exothermic reaction pathways, indicating that the extinction limits are strongly coupled with OH concentration. Numerical simulations demonstrated that the radical pool decreased, particularly the OH and H concentration via abstraction reactions of toluene, led to rapid approach to the extinction limits. The extinction strain rate of the blended fuels was analyzed and based on the variation of the radical pool concentration, which can be represented by the H/C ratio of blended fuels.


One area of human-computer interaction that has not been explored is the use of haptics in program tutorials. Many complex programs, such as 3D Studio Max, have crowded graphical user interfaces. Although this cannot be avoided, it can be frustrating to individuals trying to learn these programs, especially since the written tutorials provided as learning materials have a tendency to be difficult to understand. This paper focuses on utilizing haptic feedback to clarify such program tutorials, in particular a 3D Studio Max modifier tutorial. An experimental study was conducted to examine the effects of adding haptics to a 3D Studio Max tutorial. The results show that adding haptics decreases the amount of time and frustration it takes to learn a new computer application.

| In video communication sytems based on motion-compensated prediction coding, transmission errors cause spatial and temporal distortion propagation during the reconstruction of the video sequence at the receiver. Two commonly used techniques to stop error propagation in the reconstructed sequence are periodically refreshing the image by intra-frame coding and retransmission. However, the high bitrate (or low compression ratio) makes frequent intra-frame refreshing very expensive, if not impossible, in bandlimited applications such as wireless video transmission. Retransmission involves bitrate increase and additional delay which is intolerable in real-time applications. In this paper, we present a novel coding mode for video transmission which we call transmitter receiver identical reference frame (TRIRF) based interframe coding mode. Under the assumption of the existence of a feedback channel, TRIRF-frame coding constructs a new type of reference frame from the correctly received data which is identical both at the receiver and the transmitter. Motion estimation and compensation are based on the TRIRF-frame. Simulations show that TRIRF-based inter-frame coding can prevent error propagation as e ectively as intracoding while improving compression e ciency.


"If we could first know where we are, then whither we are tending, we could then decide what to do and how to do it." Abraham Lincoln The use of technology in education is at a juncture of two futures: one a dismal future--which is business as usual with limited teacher training for technology use and educators who are satisfied with what technology is available; or, the other, a bright future--a new direction that entails new thinking where technology serves as an integral component of learning and teaching. A bright future of new direction and thinking requires planning on a long-term basis--no quick-fix nor simple plans for spending, but a long-range plan that addresses the total instructional program of a school district or any 1earning institution. When one thinks of a long-range plan, obvious questions come to mind: What is included? How many years will the plan cover? What is the purpose of the plan? More important questions are: Where do we want to go? How are we going to get there? How do we know when we do get there? "Long-range planning does not deal with future decisions, but with the future of present decisions," a quote often attributed to Peter Drucker, addresses the magnitude of the above questions; Any district initiating a long-range technology planning process should ask these fundamental questions about the use of technology in the school curriculum. * Technology Plan: The Basics Planning is the process of developing and managing. A plan is a blueprint that includes goal-setting and implementation. A long-range plan coordinates resources so that goals for improvement are attained. These statements constitute the basic premise of any technology plan. A technology planning committee must agree to some "givens" or assumptions about technology and its relationship to the curriculum and school program that will serve as the plan's foundation. This foundation could be based on a number of concepts, such as: * Technology is not a panacea for the current problems facing education. * Technology is not a substitute for the basic tenets of a good learning environment. Technology serves as a tool for the learning and teaching processes. * There is no single best use of technology. * The potential power of technology is in how it meets the needs of the learner. In "A Curriculum for the Information Age," Mary Alice White states "...educators have not seen that the information technologies are as central to the operations of education as they are to business, research, and the arts. Without this understanding, there can be no conceptual flamework for the role of technologies in education. Without the conceptual framework, there has been no commitment to invest in the technologies as a rational educational investment." [1] Technology applications exist primarily on the periphery of a school's instructional program. Many technology initiatives are unconnected to the school's improvement activities and not part of any long-range plan. Some technology plans are disjointed, piecemeal and haphazard. These plans do not address the need to strategically plan for the transformation of the learning and teaching processes by using technology--a dismal future. As proposed by C. Mojkowski, a strategic approach to technology implementation should include the following: [2] * Curriculum first, technology second: The emphasis is placed on the learning process and not the hardware. What are the learning outcomes? Attention is given to thinking, problem-solving, and learning-to-learn skills within and across all content areas. * Technology linked to district and school improvements: Technology is a component of the established priorities of the community and the district. * Developing a strategic sense: A district's technology use is guided by its vision, mission and goals. …


VES-18 clean fracturing fluid is mixed with cationic quaternary ammonium and organic salt salicylate.The main behavior of VES-18 is investigated and tested on site.The results showed that VES-18 possessed a good temperature resistance and time stability.At room temperature and high shear rate of 170 s-1,the viscosity of VES-18 is about 11 mPa.s.As the shear rate increased from 200 s-1 to 1 000 s?1,the viscosity declined slowly.And the viscosity-shear rate-decreasing curve is higher than rate-increasing curve.The curve of viscoelasticity showed that the elastic modulus was always bigger than the viscous modulus at the range of the stress scan.In the test of the simulated dynamic sedimentation,the time of VES-18 is greater than the time of the higher-viscosity guanidine and glycerol,which reflected the good carrying capacity of VES-18.Both a small amount of crude oil and gel breaker PJJ could make VES-18 broken completely within 4 hours.The breaking results are satisfactory.The vis-cosity of the gel-breaking liquids is reduced to less than 3 mPa.s,and the surface tension is low.The gel-breaking liquids had no residue content and had good compatibility with the formation.


Objective To explore acceptability of biomedical prophylaxis strategies such as male circumcision,topical use of microbicides,HIV vaccine and pre-exposure prophylaxis(PrEP)and their related factors among men who has sex with men(MSM)in Beijing,China.Methods 31 MSM were recruited with snowballing sampling method in an out patient clinic of a hospital in Beijing.In-depth personal interview was conducted and qualitative data were analyzed to learn their acceptability and the related factors of these preventive measures.Results The majority of MSM studied do not view MC as a preventive measure but a clinical procedure for redundant prepuce or phimosis.Whether having an influence to the daily life,sexual pleasure and penis appearance is its major determinants.Microbicide has a higher acceptance due to advantage that can be conveniently used topically.And most of the MSM tend to use the gel formulations.HIV vaccine also has a high acceptance.However,a lot of MSM doubt about success and time needed for its development.Acceptance of PrEP in MSM is slightly lower due to worrying about side-effects in long-term use of ARV drugs,but it is still loved by some MSM due to its hidden use.Conclusions Awareness of biomedical prophylaxis is relatively lower among MSM surveyed and their acceptability varies.Educational propaganda should be done to strengthen the awareness of the HIV biomedical prophylaxis so as to provide theoretical evidence and practical guidance to their application and promotion in the future.


Cultured Narcissus tazetta var. Chinenese in the solution added with mineral element, it was found that mineral nutrition could significantly improve the net photosynthetic rate and the ratio of photosynthesis to respiration, increase the content of soluble protein and chlorophyll in leaves in the stage of sprout and flowering period, as well as reduce the activities of SOD, POD and CAT, the production rate of and MDA content of leaves in the stage of wilting. Mineral nutrition could effective prevent the over-oxidazition of membrane and the senescence of leaves.


In this work, we developed a very simple and novel approach for synthesizing TiO2-ZnO nanocomposites via the urea-assisted thermal decomposition of titanium oxysulphate and zinc acetate at different weight ratios. The synthesized nanocomposite samples were studied by means of HR-TEM, XRD, STEM, UV–Vis DRS, PL and EDS. The observed results demonstrate that the TiO2-ZnO nanocomposite consists of an anatase crystal phase of TiO2 with a crystallite size of 10–15 nm. Combined characterization, including UV–Vis DRS, STEM, EDS and HR-TEM, revealed the successful formation of a heterojunction between TiO2 and ZnO and an improvement in UV spectrum absorption. The photocatalytic activity was explored using MO degradation under ultraviolet light illumination. The results of the optimized TiO2-ZnO nanocomposite show excellent photocatalytic activity and photostability over a number of degradation reaction cycles. In addition, the current approach has immense potential to be used as a proficient method for synthesizing mixed metal oxide nanocomposites.

This paper describes the theoretical basis which underlines each of the policies recommended by Newman and Kenworthy regarding the provision of roads, parking and public transport. It outlines some of the ways in which each of these policies has been implemented in the United Kingdom. A cross sectional analysis of the data set is then provided using the 1960, 1970 and 1980 values of all the variables as three individual cross sections. The 1960, 1970 and 1980 cross sections are then combined in order to carry out a dynamic analysis of the data in which the variables under scrutiny are not levels, but are instead differences between two of the time periods. This paper was presented at the U.T.S.G. Conference, Newcastle, January 1992.

As mymentor and my sole dissertation advisor, James March, or Jim as I remember him, was essential in shaping my views on the fundamental issues of organization studies. He had a great, agile mind that was capable of pushing beyond any limits. More importantly, he was a good teacher to me. He nurtured his students to grow in his unique ways. I remember Jim's students often meeting with him for private discussions. In the spring of 1999, I began my own near weekly discussions with him. The talks varied across academic topics and ideas. They went on until the year 2003, the year I graduated from Stanford. Many of my meetings with Jim were of the brainstorming sort: they produced no 'tangible' or 'publishable' results, but they shaped my thinking and helped me mature into the type of academic standards deemed appropriate by Jim. Aside from those weekly meetings and the painful, yet fruitful, dissertation process, I closely worked with Jim during our project related to the evolution of the field for organization studies. The paper, 'Notes on the evolution of a research community: Organization studies in Anglophone North America, 1945–2000', was later published in 2005 in Organization Science (Augier, March, & Sullivan, 2005). I was also honored to witness (as a liaison, somewhat) to the formation and publication in 2005 of Jim's MOR paper 'Parochialism in the Evolution of a Research Community: The Case of Organization Studies' (March, 2005). While published earlier than our evolution of the field project, the MOR piece was an extension of the research we were doing for the evolution paper. Jim's pervasive influence on my academic career are obvious and profound. First of all, I became a full believer in bounded rationality under Jim's tutelage. Before I entered the Stanford Graduate School of Business, I had convictions that human beings are limited in terms of ability and moral capacities. The idea of bounded rationality for organizational decision-makers, thus, was highly resonant with my own personal convictions. However, it was not until I started closely working with Jim did I have a better understanding of the theory of bounded Management and Organization Review 15:4, December 2019, 891–894 doi: 10.1017/mor.2019.46


Critical Infrastructure Protection requires the prioritization of critical assets and the evaluation of the criticality of infrastructures. However, criticality analysis is not yet standardized. In this paper we examine the relation between security risk and criticality. We analyze the similarities and differences in terms of scope, aims, impacts, threats and vulnerabilities and we suggest how existing risk analysis can be applied when examining Critical Infrastructures. Based on the identified relation between risk and criticality, we propose a generic risk-based Criticality Analysis methodology. We place key emphasis on the definition of examined impact types, which are social-centric and/or sector-centric, in contrast to traditional risk analysis methodologies that mainly examine organization-centric impacts. We propose a detailed list of impact criteria in order to assess the criticality level of an infrastructure.


The proliferation of ethics committees and ethics consultation services has engendered a discussion of the issue of the expertise of those who provide clinical ethics consultation services. In this paper, I discuss two aspects of this issue: the cognitive dimension or content knowledge that the clinical ethics consultant should possess and the practical dimension or set of dispositions, skills, and traits that are necessary for effective ethics consultation. I argue that the failure to differentiate and fully explicate these dimensions contributes to the confusion over the issue of expertise and fuels, at least partly, the controversies about expertise (or authority) in ethics and the legitimacy of the use of ethical knowledge in clinical ethics consultation.


The problem of acquisition of frequency hopping multiple-access communication systems is addressed. The receiver uses the hidden preamble detector to accomplish the acquisition process. An upper bound on mean acquisition time is provided and the results are compared with an active correlator and a matched filter. The results show that the hidden preamble detector has a low-complexity detection scheme and an acquisition speed that is nearly as fast as the matched filter.


Introduction An association between cartilaginous endplate (CEP) defects and intervertebral disk (IVD) degeneration has been previously suggested in animal and cadaveric studies. There have been no previous reports in the literature that describe the use of ultrashort time-to-echo (UTE) magnetic resonance imaging (MRI) to assess the CEP in humans in vivo. As such, the purpose of this study was to report the feasibility of the UTE MRI technique to assess CEP defects in humans in vivo using and to assess their relationship with IVD degeneration. Materials and Methods Nine volunteer subjects (mean age 43.9 years; range: 22 to 61 years) were recruited, representing 54 IVDs and 108 CEPs. The subjects underwent T2-weighted and UTE MRI to assess for the presence and severity of IVD degeneration, and for the presence of CEP defects, respectively, from T12 to S1. Intervertebral disk degeneration was graded according to the Schneiderman et al classification on T2-weighted MRI. CEP defects were defined on UTE MRI as discontinuity of high-signal over 4 consecutive images and were independently assessed by two observers. Results Total 37% out of 108 (34.3%) CEPs had defects, which mainly occurred at T12/L1, L1/L2, and L4/L5 (p = 0.008). Multivariate logistic regression revealed that lower BMI (p = 0.009) and younger (p = 0.034) individuals had a decreased likelihood of having CEP defects. A statistically significant association was found to exist between the presence of CEP defects and IVD degeneration (p = 0.036).A higher prevalence of degenerated IVDs with CEP defects were found at L4/5 and L5/S1, while degenerated IVDs with no CEP defects were found throughout the whole lumbar region. Mean IVD degeneration scores of the L4/5 and L5/S1 levels with CEP defects were higher in comparison to those with no CEP defects. Conclusion Our study demonstrates the feasibility of using UTE MRI in humans in vivo to assess the integrity of the CEP. A statistically significant association was found to exist between the presence of CEP defects and IVD degeneration. In the lower lumbar region, more severe degeneration was found to occur in the IVDs with CEP defects than in those without defects. Such imaging technology may broaden the understanding of IVD degeneration and facilitate management options that target IVD repair/regeneration.

OBJECTIVE
To determine the validity of the Centor score (cervical adenopathy, tonsillar exudate, fever, and absence of catarrh symptoms) in diagnosing streptococcal pharyngitis (gold standard: throat swab).

DESIGN
Descriptive study.

SETTING
San Fernando 2 Health Centre, Madrid (outer urban area), Spain.

PARTICIPANTS
On hundred forty patients over 14 years old who had a "sore throat" as main symptom and attended clinic between 14 February and 12 May, 2005.

MAIN MEASUREMENTS
Sensitivity, specificity, positive and negative predictive values, and the probability quotients of the Centor score were determined. Pharyngeal throat culture was used as the reference method.

RESULTS
Thirty four patients had positive throat culture (24.3%; 95% CI, 17.6%-32.4%). Finding the 4 criteria in the Centor score had a positive predictive value (PPV) of 48.1% (95% CI, 30.7%-66.0%) and a negative predictive value (NPV) of 81.4% (95% CI, 73.3%-87.5%); although only fever (OR, 3.64; 95% CI, 1.40-9.49) and tonsillar exudate (OR, 6.18; 95% CI, 2.08-18.35) were linked to streptococcal aetiology.

CONCLUSIONS
The high NPV and specificity of the clinical score makes the diagnosis of non-streptococcal pharyngitis very accurate. However, the PPV is low: a high Centor score (3 or 4 criteria) does not mean streptococcal pharyngitis with certainty. What approach to take with patients suspected of streptococcal pharyngitis is not yet resolved (microbiological test, early antibiotic, or postponed antibiotic).


Welcome to SIGMETRICS 2015. SIGMETRICS is the flagship conference of the ACM special interest group for the computer systems performance evaluation community. This year marks the forty-second anniversary since SIGMETRICS (under its prior name, SIGME) held the First National SIGME Symposium on Measurement and Evaluation in 1973. The past four decades have seen enormous changes in the field of computer science, but the importance of measurement, modeling, and performance evaluation remains as critical as ever.

This year's conference includes papers on topics that have been a mainstay since the founding of our SIG, including queuing, scheduling, resource allocation, and performance measurement. Application areas that have emerged in recent years, such as data center and cloud, big data, solidstate storage, machine learning, crowdsourcing, energy optimization, continue to be represented in our program. We received 239 submissions to this year's conference, of which 32 appear in the program as full papers, which is a highly competitive acceptance ratio below 14%. An additional 24 submissions appear in the abbreviated form of poster presentations and extended abstracts.

As in some prior years, we performed reviews in three rounds. In the first round, each paper was assigned to three reviewers. In the second round, papers were up for discussion among the reviewers, especially those with highly divergent review opinions. In some cases, additional reviews were necessary to ensure that every paper would receive at least three reviews. Based on this and immediately prior to the TPC meeting, papers were bucketed into "accept", "reject", and "discuss at TPC meeting" buckets. Finally, in the TPC meeting at MIT (Cambridge, MA), we entertained comments and objections on papers in the "accept" and "reject" buckets and discuss all papers in the "discuss at TPC meeting" bucket.

It was no mean feat to winnow a set of nearly two hundred and fifty submissions down to a set of appropriate size for a three-day conference. We offer tremendous thanks to the 57 members of the program committee who collectively performed this daunting task. We are grateful for the support of the SIGMETRICS board during the lengthy process of selecting this year's conference program.

Specific emitter identification (SEI) refers to the process of distinguishing emitter individuals, which is important for electric support measure systems. Traditional SEI methods are based on hand-crafted features and have the problem of low accuracy. A novel convolutional neural network (CNN) approach, named squeeze excitation densely connected residual convolutional network (SEDCRN) approach, is therefore proposed. SEDCRN can directly recognize signals without complex preprocessing. It obtains the beneficial advantage of rediscovering new, more useful new features from low-level information and reducing feature redundancy by embedding the squeeze excitation module and residual connections into the densely connected convolutional structure. BesideIn addition, SEDCRN adopts center loss as an auxiliary loss function, which can further enhance the ability of feature learning and expression, especially for SEI tasks. The proposed approach is evaluated using a real automatic, dependent surveillance-broadcast signal dataset. Experiments show that SEDCRN outperforms traditional methods and other CNN-based methods in terms of accuracy and parameter efficiency.


Let μ>2 and ε>0 . We show that, if G is a sufficiently large simple graph of average degree at least μ, and H is a random spanning subgraph of G formed by including each edge independently with probability p≥1μ−1+ε , then H contains a cycle with probability at least 1−ε .


ABSTRACT Participants (N = 312) in romantic relationships completed an online survey to determine common integrated phone activities, motivations for integrating phones into time together, and whether phone integration is associated with relationship satisfaction. The most frequent activities included showing social media posts, photos, and videos; showing texts; and involving the partner in video calls. Primary motivations for integrating phones into partners' co-present time were enjoyment, psychological inclusion, phubbing avoidance, transparency, and habitual use. Findings indicate that participants were often intentional in integrating the phone into co-present time, and frequency of joint involvement with the phone was associated with relationship satisfaction.


Based on the Pb isotopic features, the ore leads in the continent of China can be divided
into four types: (i) single-stage lead of low μ value derived from mantle, (ii) homogeneous
lead of crustal source with high μ value, (iii) modern mixing lead between mantle and
crust, and (iv) residual lead of crustal source. As the leads from mantle had possessed single-
stage features (μ = 7.8) before the Proterozoic, the ages of continental crust can be calculated
based on the mixing Pb of type (iii). The results hidicate that the continental crust of China
was mainly generated during the Archaean, and the growth rates of crust reached the max-
ima by the ages of 3.3-3.4, 2.6 and 1.6-1.7 b.y. The occurrences of residual crust Pb
with high ~(207)Pb/~(204)Pb and ~(208)Pb/~(204)Pb anomalies were associated with the remelting and
reconstruction of crust since 1.6 b.y. ago. The lead sources in the continent of China show
higher Th/U ratios (3.3-6.5) and ~(207)Pb anomalies than those in other continents, indication
the continent of China has undergone stronger reconstruetion than other continents.


For effective arrangement of urban rail transit lines,considering traffic zones being divided,the accessibility constraint and the constraint of the rail transit network's size,the bi-level programming model for urban rail transit network's layout was set up.The upper level of this model is a multi-objective function which is to minimize the total travel time and the total rail transit lines' length and the total transfer times,and the lower level of the model is a capacity-constrained traffic assignment model that describes passenger flow assignment on the rail transit network.The results of an illustration show that the reasonable rail transit lines can be selected from all possible lines and the optimal scheme of the rail transit network's layout can be obtained using this bi-level programming model.This model can be used in urban rail transit's planning for optimizing the rail transit network's layout.


Sapium sebiferumis one of the most important oil trees.SAD(stearoyl-acyl ACP desaturase) protein is a dehydrogenase,which is a key factor for transforming saturated fatty acid to unsaturated fatty acid in oil plant.We expressed and purified SsSAD from Sapium sebiferumin E.coli to investigate its function.The result suggested that:(1)The full length cDNA encoding SsSAD was amplified by RT-PCR fromSapium sebiferumand cloned into cold shock inducible expression vector pCold TF.The recombinant prokaryotic expression plasmid was transformed into E.coli BL 21star(DE3)strain for gaining of the genetic engineering strain.(2)The transformed strain was induced with IPTG(isopropylthio-D-galactoside) for expressing fusion protein at low temperature.Results showed that the recombinant protein with a molecular mass 101kD was highly expressed in E.coli and present both in the supernatant and the pellet part of E.coli lysates.The supernatant was further purified by affinity chromatography and detected by Western blotting,which demonstrated that high quality recombinant protein was obtained and laid the founda-tion for investigation on the structure and function of SsSAD.


Recently there has been more complaints about how pesticides are used throughout the World with concerns about their presence in soils, in harvested produce and the possibility that various illnesses were caused by exposure to pesticides. The initial criticisms date back to Rachel Carson
 (1962) who was concerned about the impact of DDT and other chlorinated hydrocarbon insecticides. This led to the establishing of the Rotterdam Convention about the movement of highly hazardous pesticides and established standards of information exchange, essentially to warn countries not to
 import these chemicals. A subsequent Stockholm convention considered the wider problem of persistent chemicals in the environment. Nevertheless, the agrochemical industry has continued to market a wide range of these pesticides. In the countries with a more temperate climate, the requirement
 of training those applying the pesticides, usually with tractor equipment and use of protective clothing, problems caused by using many pesticides have not been so evident compared with more tropical countries, using mostly manually carried and operated sprayers with little or no training
 on how or when pesticides should be applied.


AN EVALUATION WAS MADE OF THE APPLICATION OF THE TROXLER NUCLEAR ASPHALT CONTENT GAUGE, MODEL 2226, TO DETERMINE THE ASPHALT CONTENT OF HOT BITUMINOUS MIXES USING NEUTRON THERMALIZATION. PARALLEL DATA WERE ACQUIRED, WHERE CONVENIENT, BY THE USE OF A NUCLEAR-CHICAGO ASPHALT CONTENT GAUGE, MODEL 9999, PREVIOUSLY EVALUATED. DATA WERE FIRST ACQUIRED FOR VARIABLES OF MIX DESIGN (GRADATION), AGGREGATE TYPES, AND ASPHALT PROCEDURES FOR BITUMINOUS MIXES WITH VARIOUS REPRESENTATIVE ASPHALT CONTENTS. THESE INITIAL SAMPLES WERE MIXED UNDER CONTROLLED LABORATORY CONDITIONS. COMPARISONS WERE MADE OF DESIGN ASPHALT CONTENTS, IMMEREX EXTRACTION VALUES ON THE SAME SAMPLES, AND THE VALUES DETERMINED WITH THE TWO NUCLEAR UNITS. FIELD TESTS OF THE TROXLER GAUGE WERE ALSO CONDUCTED AT VARIOUS BATCH PLANTS WITH RESULTING VALUES COMPARED TO EXTRACTED ASPHALT CONTENT ON THE SAME SAMPLE.


The article describes different types of derivatives with the prefix mega- in the English language in terms of word-formation meanings. The study of the component of ancient Greek origin functioning in a synchronic and diachronic perspective made it possible to establish the reasons and describe the mechanisms of its further derivational transformations in English language. In the receiving language, the adjective μέγας undergoes cross-level conversion and is used as a prefix element in various derivatives. The quantitative semantics that is genetically inherent in the component is implemented as a part of terminological units in which the prefix acts as a term element. In other types of discourse, the quantitative identification function is combined with the function of evaluation. In derivatives related to popular science or commercial discourse, the prefix mega- serves to distinguish an object from a number of similar ones and marks it as an exceptional phenomenon. The method of profiling used in the analysis made it possible to describe the internal mechanism of word-formation meanings of derivatives with the prefix mega- . Contextual analysis and survey of informants (native English speakers) allowed for differentiation between the meaning of mega- and super- prefixes used in the evaluation function. It has been found that in English derivatives, the prefix mega- marks the highest degree of the quality and is attached to the bases, which referents could be evaluated in the terms of quantitative characteristics. The addition of the prefix super- is not related to parametric characteristics in the meaning of the root morpheme, which determines its assessment by native speakers as a marker of a lower degree of evaluated quality.


The Selected Titles project has developed a list of current popular titles to serve research libraries outside the United States as a collections development guide for English-language monograph. Visual Basic software was used to identify titles from the OCLC Online Union Catalog that are: 1) held by at least ten research libraries; 2) published after 1990; and 3) published by any of the 50 publishers most frequently represented in the sample


CROSSING O W R FROM STUDENT TO TEACHER: NEGOTIATING AN IDENTITY A thesis submitted in conformity with the requirements for the degree of Doctor of Education, Graduate Department of Education, The University of Toronto, by Carol A. Beynon, 1996. In this study 1 use a dialogic process with two student teachers, two of their universicy teacher educators , and their s Ur cooperating teachers to investigate how student teachers l e m to teach. By listening to the voices and analysing the tex& of the major participants in the teacher education process, I identify some of the diiemmas that exist in the professional education of teachers. Six paradoxes emerge from the discourse with the student teachers that cause them to feel a loss of control in their search for personal meaning as an emerging teacher. As they consider the contradictions during the preservice program, the student teachers alter their personal expectations and begin to reconcepnialize their views of teaching. At the same tirne, 1 examine the discourse and practices of the school-based and university-based teacher educators' roles in order to determine how they contribute to or help solve the contradictions which the student teachers encouter. The major fuiding in this study relates to the value of the dialogic process which the student teachers and teacher educators participated in as part of this research project. The dialogic practice seems to have a profound effect on the student teachers' visions of themselves as teachers. The implications of this inquiry are used to promote ideas for transformation in teacher education. There have been many people who have supporteci and assisted me through the doctoral process and 1 wish to acknowledge and thank them for their insight, patience, and perseverance. First, my sincere appreciation to Tracy, Carlo, Cheryl, Susan, and the six cooperating teachers who gave of their t h e , enthusiasm, and creative ideas to my work. Al1 of them were so busy with their own professional lives, yet offered willingly to meet with me and invited me to their classrooms. Thank you for your contributions and your re-reading of my work. Without you, this study would not exist! Dr. David Corson, my thesis supervisor, provided a source of support and inspiration during this project as well as constant positive reinforcernent and encouraging recommendations. He was only just an E-mail message away and constantly available for advice when asked.

The synthesized gold nanoparticles using indole-3-carbinol (AuNPI3Cs) has been characterized and its antineoplastic activities has been studied here. Several techniques have been used to characterize the AuNPI3Cs. Ultraviolet spectroscopy studies indicated the stability of the synthesized AuNPI3Cs, while FTIR analysis proved that indole-3-carbinol was playing an important role in stabilizing the AuNPI3Cs. TEM analysis study showed that AuNPI3Cs were mostly spherical in shape with an average particle size of 3 nm. The selected area electron diffraction pattern exhibited the crystalline nature of AuNPI3Cs, which was further proved by XRD studies. The present study describes the in vitro antineoplastic efficacy of AuNPI3Cs against Ehrlich ascites carcinoma (EAC) cells. Results showed that the IC50 dose of AuNPI3Cs was significantly capable of elevating intracellular reactive oxygen species. AuNPI3Cs induced apoptosis by increasing the G2/M population, LIVE/DEAD cytotoxicity, chromatin condensation, DNA laddering and TUNEL-positive cells significantly (p < 0.001). Reduction of the mitochondrial potential by AuNPI3Cs was substantiated by JC-1 fluorescent staining. These findings will enlighten future biomedical applications of gold nanoparticles using indole-3-carbinol (AuNPI3Cs) as an antineoplastic agent.


The static and dynamic force-force correlation function for the one-dimensional Toda lattice is calculated in the soliton-gas approximation. The dispersion and width of the soliton and phonon resonances are discussed in detail. Comparison with other calculations and molecular dynamics results shows that this approximation gives a reasonable description of most of the features in the correlations.


The main focus of this work is to establish a protein synthesis pathway for T7 RNA polymerase (T7-RNAP) and Pumilio and fem3 mRNA binding factors 6 (Puf6) using the minimum necessary methods.The proteins can be cost-effectively expressed pure and highly active in prokaryotes and then effectively purified with a hexahistidine tag via nickel-NTA affinity chromatography. The proteins find application in the synthesis and folding of, for example, ribosomal RNA (rRNA). This paper describes the optimisation of T7 and Puf6 synthesis to ensure the highest possible yield and purity, both indispensable factors for research and biotechnological applications. research and biotechnological application of the proteins.


In this paper, E-plane multiway waveguide power dividers consisting of many steps, many sections, and corners are treated. Practical dividers with a small size and a broad bandwidth are designed. In general, in a structure with various discontinuities placed close together, it is necessary to take into account the mutual interactions among the propagating and nonpropagating modes. The design method based on the E-plane planar circuit approach and the segmentation/desegmentation method used in this paper can provide accurate circuit characteristics with simple matrix calculations. Therefore, optimal design of a circuit configuration consisting of several discontinuities can be performed within a short time. First, the trifurcated and tetrafurcated dividers for the X band are designed. Next, an integrated design is attempted for three- and fourway dividers with mitered bends at the output ports. As a result, flat power dividing characteristics over the entire X-band are obtained. The validity of the present design method is confirmed by means of an electromagnetic field simulator (HFSS) and trial experiments. © 2003 Wiley Periodicals, Inc.

Magnetic hysteresis properties were measured on dispersed synthetic milled titanomagnetite (Fe 2.3 Ti 0.7 O 4 ) particles in the range 1-125 μm and after annealing. Milling is thought to introduce internal stresses in the particles by increasing the dislocation density that is reduced again by annealing. Thus, it was intended to investigate the stress-dependence of magnetic parameters. The particles were examined by mineralogical and crystallographic methods in the milled state and after annealing. Small particles (1-2 μm) were very inhomogeneous after milling with anisotropic strains and a crystallite size of 50 nm as found from X-ray line broadening ; annealing led to increased crystallite size but hardly reduced strains. For larger grains, an outer 1 μm thick 'damaged' shell was detected that could be removed by etching or recrystallized by annealing. After these procedures, particles showed reduced coercive force and reduced relative saturation remanent magnetization. The two-shell behaviour of milled 10-15 μm particles could be seen from wasp-waisted hysteresis curves that disappeared after etching or annealing. For larger particles these effects were reduced.


The invention discloses a method for preparing alloy powder for metal injection moulding through atomization, which comprises the following process flows: melting an alloy raw material at a temperature of between 1,500 and 1,700 DEG C into molten steel in an induction melting furnace, and pouring the molten steel into an atomizer in a flow rate of 8-15 kilograms/minute through a bottom pour ladle; shredding the molten steel flow into fine particles of which the average grain diameter is less than 30 mu m by waterflow under a high pressure of between 50 and 120 MPa through a nozzle; and performing solid-liquid separation, drying and classification, mixing with powder with other alloy components to prepare the atomized alloy powder for the metal injection moulding with a plurality of alloy components. The method can prepare the alloy powder of which the particles have the average grain diameter between 30 and 80 mu m; the physicochemical properties of the powder meet the requirement of an injection moulding process; and the basic powder is mixed with alloy powder, and other alloy powder can be produced by adjusting the mixing ratio, and is used for manufacturing injection moulding parts with different purposes, so that the value-added content of products is improved and the injection moudling parts have wider applicability.


Controlled human infection (CHI) studies have been performed previously with a range of virologic, bacteriologic, and parasitic agents, yielding important information on immunopathogenesis, duration of vaccine-induced immunity, and to define correlates of protection in healthy populations (1–3). CHI can also provide key safety, tolerability, immunogenicity, and efficacy data supporting vaccine research. Typically, in a CHI experiment, participants are given a test vaccine and are inoculated 2–4 weeks later with the pathogen of interest via the most physiologically relevant route of administration. Such experiments require only a few months to complete, and the number of participants enrolled is usually rather in the tens than in the hundreds, let alone in the thousands or ten-thousands needed for phase 3 Randomized Controlled Trials (RCTs). The COVID-19 pandemic has a major impact on global health. Currently (February 2021), more than 110 million people have (had) an infection with SARS-CoV-2, and nearly 2.5 million died of COVID-19. Large parts of the world are in the second wave, with no view of imminent solutions, although vaccine development is continuing at unprecedented speed. A number of clinical trials are already ongoing with 73 candidates, including 16 candidates in phase 3 (4). Although the Pfizer/ BioNTech, Moderna and AstraZeneca vaccines have been fully evaluated and licensed for emergency use, a second wave of vaccines is under development and worthwhile to become available, given the global market need to cover immunization of seven billion people. If some of the vaccines need two doses to complete primovaccination, that brings the global need quickly to 10 billion doses or more. Today, we cannot say if this will be a yearly need, since duration of immunity will only be known later on. In addition, it cannot be excluded that mutations require quick adaptation of vaccines to potentially new strains. To mitigate the risks of efficacy and availability, we will have to rely on a range of vaccines. Admittedly, RNA vaccines, nanoparticle vaccines, and virus like particle vaccines (5, 6) can be produced substantially faster compared to conventional expression systems (7), under the assumption that manufacturing facilities are up and running, with sufficient supplies and staffing. For example, in the case of inactivated or live-attenuated viral (such as virus vaccine candidates being produced in cell lines), or recombinant protein vaccine candidate production, product-specific manufacturing


The deregulated electricity sector needs an improvement in the Available Transfer Capability (ATC) towards the maintenance of power network at balanced condition and to utilize the system in effective manner. Independent System Operator (ISO) maintains the ancillary services by ensuring the reliability of the power system. One of the major functions of ancillary service provider is to maintain the voltage and power flow at stable level. To improve the ATC, both the line power flow and bus voltage profile have to be modified and it is taken care by the ISO. The major limiting criterion for ATC is bus voltage profile. It is well known that the device Thyristor Controlled Series Compensation TCSC which is one of the Flexible AC Transmission System (FACTS) devices can modify the line flow by adjusting the line reactance and Static VAR compensator (SVC) can improve the bus voltage profile by injecting reactive power to the bus. In this research, an Artificial Neural Network (ANN) based estimation of control parameter of FACTS devices such as TCSC and SVC for ATC enhancement is used. The proposed approach uses two different ANN network to find the different TCSC and SVC control parameters to improve the ATC values without violating its voltage constraints for real time transactions. The ANN algorithms such as Radial Basis Function (RBF) as well as Back Propagation Algorithm (BPA) were used to find the TCSC and SVC Parameters and the results are compared. The proposed methods are demonstrated through Reliability Test System (RTS) of IEEE 24 bus. The simulation output represents the suitability of the anticipated method for Real Time estimation of FACTS devices control parameter settings for ATC Enhancement.


Although correlations between marital conflict histories and increased reactivity by children during conflict exposure are well documented (i.e., sensitization), questions about causality remain unresolved. This study subjected the sensitization hypothesis, which is a critical prediction of several theories about interparental conflict, to an experimental test. Children in 3 age groups (early childhood, preadolescence, late adolescence) viewed videotapes of an adult couple engaged in a history of (a) 4 hostile, unresolved conflicts (destructive) or (b) 4 mild, resolved conflicts (constructive). Next, all children were interviewed about their responses after witnessing a standard conflict between the same adult couple. Supporting the sensitization hypothesis, destructive conflict histories elicited more negative patterns of responding across multiple domains; age and gender moderated many effects. Results suggested that constructive conflict histories had benign effects on children.


The question we investigate is how to obtain PLC applications with confidence in their proper functioning. Especially, we are interested in the contribution that formal methods can provide for their development. Our maxim is that the place of a particular formal method in the total picture of system development should be made very clear. Developers and customers ought to understand very well what they can rely on or not, and we see our task in trying to make this explicit. Therefore, for us the answer to the question above leads to the following questions: Which parts of the system can be treated formally? What formal methods and tools can be applied? What does their successful application tell (or does not) about the proper functioning of the whole system?


Item-level tagging has been required to the retail market with densely placed items as well as the production line. Owing to the multi-path fading, the blind spots where the tag is non-responsive can be created. Furthermore, in case of the indoor radio-frequency identification (RFID) localisation system, additional circuits and localisation algorithms are indispensable for accurate localisation of RFID tags. In this study, in order to solve this problem, the beam-controlled antenna array with a quadruple beamforming network which generates multiple beams is presented for ultra-high-frequency (UHF) RFID systems. The proposed quadruple-feed antenna array can cover the wide spatial coverage, and the main beam directions of the proposed array can be controlled by selecting the appropriate input port of the quadruple network. The fabricated antenna array with the quadruple-feed network operates at the 902-928 MHz band and produces scannable multiple beams for UHF RFID localisation system within the wide interrogation zone.


This paper presents the dynamic analysis of a multimachine small-hydro power system. Various mathematical models including hydraulic turbine prime mover model, induction generator model, electromechanical model, power factor correction capacitor bank model were employed to cater for the dynamic behavior of the system operating in load importing, load exporting, sequentially starting, and three-phase balanced fault situations. Simulation results showed that the system operated satisfactorily under those conditions. The dynamic study at preliminary planning stage is essential for a small-hydro project prior to construction.

Acquired hepatocerebral degeneration (AHD) and hepatic encephalopathy (HE) are neurological complications of chronic liver disease (CLD) with portosystemic shunt. While HE is common, AHD is a rare entity, and the clinical imaging relationships observed in small series lack validation in large patient cohorts. The aim of this study was to characterize a cohort of AHD patients and to explore possible associations with HE coexistence.


On the Heterogeneous-Catalytic Oxidation and Ammoxidation of Isobutene. IV. Influence of n-Butene on the Heterogeneous-Catalytic Oxidation of Isobutene to Methacroleine

The influence of n-butenes 2 on the oxidation of isobutenes 1 to methacroleine 3 has been investigated in presence of a catalyst containing Bi, Mo, P, Fe, Mg, Mn, Si and O. Addition of 2 to the gas mixture increase the selectivity and yield of 3. This fact can be correlated by decrease of oxygen partial pressure in consequence of the dehydrogenation of 2 to butadiene 4.


Statistics of fire numbers and floor areas of buildings within the past 20 years were integrated to produce fire probability, frequency, and cycle of each building categories in Taiwan. The National Fire Agency, Ministry of the Interior (MOI), and the local government fire bureaus conducted an extensive investigation into building fire cases ranked as "conflagration" or "large fires" according to fire damage ranking. Data were acquired on 311 fire incident cases with the relevant cause, time, location, number of casualties, and loss. This study also used research from other documents to produce 20 fire safety assessment criterions and 4 fire safety strategies. Local government fire bureau specialists were requested to complete a questionnaire using the 20-fire safety assessment criterion based on these 311 fire cases. The results are represented using calculated weight values for the 20 fire safety assessment criterions and 4 fire safety strategies. These precise quantified data will be employed as the reference for proprietors to improve the fire safety measures for their buildings and carry out the building fire management and prevention.

not limited by the author's preferences (cf. pp. 422 ff.), rather, a pattern of arguments that defined a discipline. The last two parts of the book move from uncertainty to decision. They deal with ijtihad and iftd' (part 3) and the methodology of juristic preference (farjih) (part 4). There was, in the end, a need for decision, for at least a temporary stasis in the exploration of God's law. This is what lies behind the theory of ijtihad. Usually denned as the expenditure of the utmost possible effort in the search for a rule of law, ijtihad resulted in, not knowledge, but opinion. That opinion, however, for as long as it lasted, and under conditions that had to be stated, analysed and explored, was binding both on the mujtahid and on those who, ignorant of texts and hermeneutical principles, relied on others for their knowledge of the law. The practical question of how to tip the balance (farjih), given the array of relevant principles and the generous acknowledgement of uncertainty, got scanty attention from AmidI and correspondingly little from Weiss. Part 2 is more than 500 pages, part 4 only ten pages long.


Indonesians, particularly those residing in rural areas with abundant plant diversity, have long relied on traditional medicine that utilizes plants. Sungkai (Peronema canescens Jack.) is one example of a widely-used traditional medicine known for its immunity-boosting properties. However, many people need more awareness of the potential benefits and risks of plants like Sungkai, so it is necessary to provide education and training to promote proper usage and ensure public safety. This community service activity aimed to equip individuals with the knowledge and skills to process plants accurately, utilize them appropriately based on the severity of the illness, and avoid any adverse side effects or toxicity. The counselling method used in this initiative involves lectures, which is effective for individuals with varying education levels, especially the general public. This program has yielded promising results, with the community displaying strong enthusiasm for the initiative. Ultimately, education and counselling services can significantly improve public understanding and use of traditional medicine.


ABSTRACT Differences in milling behavior among hard-type common wheat (Triticum aestivum) cultivars are well known to millers. Among them, the French cultivar Soissons, which contains the Pinb-D1d allelic form of the puroindoline b gene, is particularly distinguished for its high milling value. Near-isogenic lines (NILs) differing by the allelic forms of the puroindoline b gene, Pinb-D1d or Pinb-D1b (one of the most frequent alleles found in the European wheat population), were constructed. Grain characteristics obtained after wheat cultivation in distinct environmental conditions were compared between NILs and the cultivar Soissons, as was their fractionation behavior. Results showed that NILs containing the Pinb-D1d allele displayed lower values of grain hardness and vitreousness than did the corresponding lines containing the Pinb-D1b allelic form under the same cultivation conditions. Both genetic background and environmental conditions appeared to affect grain texture. Measured single-kernel characte...


Orbital lymphoma is a rare cause of primary Non Hodgkin lymphomasand represents a major cause of orbital malignancies, usually arising from extraocular muscles, eyelid, and soft tissue adnexa. Overall it presents as an extraconal tumor featuring a broad spectrum of clinical presentation making the diagnosis sometimes challenging. We report the case of a 65 year old male with no prior medical history presenting with a recent ongoing proptosis. Radiological findings were consistent with an extraconal lesion involving the lateral orbital wall responsible for mass effect on the globe and optic nerve, for which histopathological results showed features of a small lymphocytic lymphoma.


We study the Landau level spectrum of a two-dimensional hole gas in carbon δ-doped (100) GaAs/Al0.4Ga0.6As square quantum well (width of 15 nm) by means of microwave cyclotron resonance (CR) and tilted field magnetotransport. Only one type of hole, with an effective mass of 0.4me, was detected in CR. By analyzing the spin-splitting level coincident conditions at B∼1 T, we find that the effective g-factor is large enough to cause Landau level crossing even in zero tilt, and the product of gm∗ increases with total magnetic field.


Radiculomyelitic (silent) rabies and acute disseminated encephalomyelitis have similar clinical presentations but distinct management and prognostic implications. It is thus important to differentiate between the two antemor-tem. Because of their distinct pathologic abnormalities, MR imaging may be helpful in distinguishing between the two entities. We report a case in which MR imaging helped us to diagnose silent rabies antemortem, which was subsequently confirmed at autopsy. Rabies is the most formidable encephalitis with unique clinical presentation almost always resulting in death. Radiculomyelitic rabies occurring after rabies postexposure prophylaxis after animal bite is often clinically difficult to differentiate from acute disseminated encephalomyelitis. Although MR imaging of the encephalitic form of rabies has been reported, this case further describes the MR imaging findings of the radiculomyelitic form and how it differs from the typical imaging presentation of acute disseminated encephalomyelitis. A 10-year-old boy presented with a history of fever that was present for 6 days, progressive weakness of both lower limbs for 4 days, and extreme agitation with behavioral changes for 2 days before admission. Although a history of hydrophobia was not forthcoming, the patient had been bitten by a stray dog 25 days previously on the left lower limb. Fifteen days after the bite, a course of Rabipur vaccine had been administered. The patient, however, had not received anti-rabies immunoglobulin. The dog was alive even 15 days after the bite. An examination performed at admission revealed that the child was in altered sensorium (Glasgow Coma Scale score, E3M4V2) that worsened during his hospital stay. There was symmetrical weakness of lower limbs with areflexia. There were no meningeal signs. The results of a fundus examination were normal at admission. Initially, clinical differential diagnoses of acute disseminated encephalomyelitis and silent rabies were considered. The weakness progressed to involve the upper limbs during a period of 48 hours. Four days after admission, the patient developed poor respiratory efforts, probably because of involvement of the brain stem. Manually administered intermittent positive pressure ventilation was started. Clinical investigations revealed normal hemogram, electrolytes, and chest radiograph. A CSF examination showed mild pleocytosis with lymphocytic predominance with normal biochemistry. Gram staining revealed no microorganisms, and the culture was sterile. The results of antigen detection tests (for meningococci, pneumo-cocci, and Haemophilus influenzae) were negative. A corneal smear and skin biopsy did not show antigen on immunofluo-rescence. The results of nerve conduction velocity studies were normal. CT of the head was …


An endo-1,3-β-glucanase from Arthrobacter sp. was purified by ammonium sulfate precipitation, anion-exchange and gel-filtration chromatographies. SDS/PAGE and gel-filtration chromatography suggested a monomer enzyme with molecular mass of 32,500. N-terminal sequence for 10 residues was APGDLLWSDE. Stable and optimum pHs were 5 to 8 and 6.5, respectively. Optimum temperature was 55°C , however, above 50°C its activity was lost rapidly. The Michaelis constant Km for laminaritetraose, laminaripentaose, laminarihexaose, laminariheptaose, and laminarin were 0.12, 0.11, 0.067, 0.066mM, and 0.16mg/ml, respectively. Curdlan and lichenan were also hydrolyzed. The purified enzyme did not give product by digestion with endoglycosidase H (Streptomyces griseus), indicating that the carbohydrate moiety was little consisted in the enzyme protein, if any, with N-linked chain or other type linkage. It was suggested that the enzyme belong to the family 16 of glucosyl hydrolase from the properties as above mentioned.

Despite the success of automated machine learning (AutoML), which aims to find the best design, including the architecture of deep networks and hyper-parameters, conventional AutoML methods are computationally expensive and hardly provide insights into the relations of different model design choices. To tackle the challenges, we propose FALCON, an efficient sample-based method to search for the optimal model design. Our key insight is to model the design space of possible model designs as a design graph, where the nodes represent design choices, and the edges denote design similarities. FALCON features 1) a task-agnostic module, which performs message passing on the design graph via a Graph Neural Network (GNN), and 2) a task-specific module, which conducts label propagation of the known model performance information on the design graph. Both modules are combined to predict the design performances in the design space, navigating the search direction. We conduct extensive experiments on 27 node and graph classification tasks from various application domains, and an image classification task on the CIFAR-10 dataset. We empirically show that FALCON can efficiently obtain the well-performing designs for each task using only 30 explored nodes. Specifically, FALCON has a comparable time cost with the one-shot approaches while achieving an average improvement of 3.3% compared with the best baselines.


Title: Sensation seeking and alcohol use: The mediating role of perceived risks and benefits. Abstract: Sensation seeking is one of personality variables more closely linked to the adoption of different risk behaviors, especially the use of al- cohol and other drugs. In addition, sensation seeking influences valuation made by individuals about the risks and their possible consequences. The objective of this study is to analyze the relationship between sensation seeking and the consumption of alcohol in a sample of 356 young people aged between 18 and 25 years. In addition, we wanted to explore the pos- sible effect mediator of biased perceptions of individuals about the poten- tial risks and benefits associated with alcohol in the relationship between the personality and alcohol consumption. The results confirm the im- portance of sensation seeking in the explanation of the consumption of al- cohol among young people and the mediating role of perceptions of risks and benefits in the explanation of the relationship. In the discussion of the work discussed their important practical implications when designing spe- cific interventions aimed at preventing the risks associated with the con- sumption of alcohol in young people.


Background: Acute lower respiratory infection (ALRI), primarily pneumonia and bronchiolitis, is a substantial cause of morbidity and mortality in children <5 years of age, particularly in developing countries. Vitamin D deficiency is a significant risk factor for severe ALRI in Indian infants and children <5 years of age. This study was done to determine the relationship, if any, between respiratory illnesses and serum vitamin D status. Methods: This study included 40 (22 boys and 18 girls) hospitalized children of 6 months to 5 years of age with ALRI as cases and 40 (25 boys and 15 girls) age and sex matched children with no respiratory illness and no clinical manifestation of vitamin D deficiency as controls. Sociodemographic profile, feeding history, immunization history, sun exposure, drug history, causes of admission were taken by interviewing the child's mother or guardian. Serum vitamin D was estimated using commercially available kit by chemiluminiscence technique. General physical and systemic examination with emphasis on respiratory system was performed. ALRI diagnosis was made by clinical, radiographic and biochemical findings. Results: Among vitamin D deficient and insufficient children, 71% and 74% were adequately exposed to sunlight respectively. 50% vitamin D deficient children were diagnosed of bronchial asthma and 33% of bronchopneumonia. Among vitamin D insufficient, 48% had acute bronchiolitis and 35% had bronchopneumonia. Among sufficient Vitamin D, bronchopneumonia and acute bronchiolitis were 36% each i.e. most of the cases of bronchial asthma (60%) had vitamin D deficiency whereas majority of acute bronchiolitis cases (73%) had vitamin D insufficiency. Statistically significant difference was seen between cases and control among vitamin D sufficient, insufficient and deficient groups with higher number of sufficient vitamin D controls. Low vitamin D levels were significantly correlated with ALRI. Conclusions: Subclinical vitamin D deficiency is significant risk factors for severe ALRI in Indian children of less than 5 years of age.


The DNA library of Erwinia chrysanthemi isolation CSCL006 was constructed. The hrpNCSCL006 gene was cloned from the DNA library and the nucleotide sequence was determined. The nucleotide sequence of hrpNCSCL006 revealed a coding region of 1 020 bp which matched well with the size of hrpNCSCL006 transcript determined by Northern blot. Alignment of the deduced amino acid sequence of harpin CSCL006 with harpin sequences of other soft-rot Erwinia species in database demonstrated that harpin CSCL006 shares high homology with harpins of Erwinia chrysanthemi strains EC16 and 3937, but relatively lower homology with harpins of Erwinia carotovora subspcorotovora. hrpNCSCL006 was cloned into a expression vector pET28a(+) and overexpressed in Escherichia coli. The ca. 34 kD overexpressed polypeptide matched well with the size of predicted harpinCSCL006. Using anti-harpinEcc antibodies as probe, Western blotting analysis confirmed that the overexpressed protein was harpinCSCL006. The harpinCSCL006 fractionated from E. coli could elicite the hypersensative reaction in tobacco (Nicotiana tabacum) leaves.


Polyester fibre has a series of excellent properties and it has a wide range of uses. Recently China has become the largest producer and consumer of polyester in the world. The purpose of this paper is to analysis the environmental impacts of polyester shirts. Applying life cycle assessment to polyester textiles, through the analysis and research of resource utilization and environmental emissions during the life of polyester textiles, looking for opportunities to reduce environmental pollution, and providing reference for environmental management departments to develop environmental regulations and environmental emission reduction plans. The declared unit of this paper is a piece of T-shirt 100% made of polyeater fibre. Following the principles and guidelines of ISO series, this study collected both measured data of the client's processes and secondary data. The data in this paper mainly comes from the literature, life cycle assessment (LCA) databases, and emission registration database of the government. The results of the study show that PET production, yarn manufacturing, and use-phases are the procedures that contribute the most environmental impacts. The total life-cycle energy use of a polyester sports shirt is 109 MJ, with 2882 litres of cumulative water use and contribution to global warming equivalent to 81.62 kg of CO2. The shirt's use phase contribute the highest resources used, accounting for 65.5% of energy use, 86.71% of water use, and 84.31% of the global warming potential. The shirt production phase accounts for 30.85% of the energy use, 13.14% of total water use, and 12.99%of the global warming potential. Disposing phase contribute less among these process. The results of the study show that PET production, yarn manufacturing, and use-phases contributes to the majority of all environmental impacts. Polyester production and yarn manufacturing are steps that require the highest amount of energy. Utilizing recycled polyester fibres can reduce the net resource utilization and environmental impacts. A large amount of energy and water are used in the use-phase of a shirt. Improving the equipment efficiency can decrease the input energy and water consumption.


Abstract : Objective: To characterize the post-irradiation conversion of a silorane composite. Specifically, to determine the time and amount of conversion that occurs for the selected silorane composite, and to compare these parameters with those established in the literature for methacrylate based composites. Methods: Silorane composite (Filtek LS) samples of 0.5 mm thickness were placed on the attenuated total reflectance (ATR) attachment of a Fourier Transform Infrared Spectroscopy(FTIR) device. Spectra were measured immediately after photo curing and at specified post-irradiation times up to 10 days.


We propose a universal decomposition of unitary maps over a t nsorial power ofC, introducing the key concept of phase maps , and investigate how this decomposition can be used to implement unitary maps directly in the measurement-based model for quantum computing. Specifical ly, we show how to extract from such a decomposition a matching entangled gr aph state (with inputs), and a set of measurements angles, when there is one. Next, we check whether the obtained graph state verifies a flow condition, which guarantees an execution order such that the dependent measurements and co rrections of the pattern yield deterministic results. Using a graph theoret ic characterization of flows, we can determine whether a flow can be constructed for a g raph state in polynomial time. This approach yields an algorithmic proce dur which, when it succeeds, may produce an efficient pattern for a given unitar y.


Abstract A new type of macroporous ellagitannic acid resin (EAR) can be prepared from macroporous crosslinked chloromethylated polystyrene beads and ellagic acid in the presence of NaOH and KI as catalysts. The synthetic route and structure of the polymer were examined. The structure of EAR was confirmed by elementary analysis and IR spectra. The oxygen content of EAR was 7.06%, and the functional group capacity of EAR was 0.441 mol EA/g EAR. The conversion of functional groups was 8.33%. Cu2+, Fe3+, Ce3+, and La3+ can be easily adsorbed by EAR. The adsorption capacities for these metal ions per g EAR were 0.609 mmol Cu2+, 1.523 mmol Fe3+, 0.320 mmol Ce3+, and 1.561 mmol La3+. The influence of pH, acidity, ionic concentration, adsorption time, and temperature on the percentage of adsorption was investigated.


This paper summarizes our research efforts in functional modelling of the relationship between the acoustic properties of vowels and perceived vowel quality. Our model is trained on 164 short steady-state stimuli. We measured F1, F2, and additionally F0 since the effect of F0 on perceptual vowel height is evident. 40 phonetically skilled subjects judged vowel quality using the Cardinal Vowel diagram. The main focus is on rening the model and describing its transformation properties between the F1/F2 formant chart and the Cardinal Vowel diagram. An evaluation of the model based on 48 additional vowels showed the generalizability of the model and conrmed that it predicts perceived vowel quality with sufcient accuracy.


Background
Worldwide, millions of deaths each year are attributed to alcohol. We sought to examine French people's beliefs about the risks of alcohol, their correlates, and their associations with alcohol use.

Methods
Data came from the 2010 Baromètre Cancer survey, a random cross-sectional telephone survey of the French general population (n = 3359 individuals aged 15-75 years). Using principal component analysis of seven beliefs about alcohol risks, we built two scores (one assessing risk denial based on self-confidence and the other risk relativization). Two multiple linear regressions explored these scores' socio-demographic and perceived information level correlates. Multiple logistic regressions tested the associations of these scores with daily drinking and with heavy episodic drinking (HED).

Results
About 60% of the respondents acknowledged that alcohol increases the risk of cancer, and 89% felt well-informed about the risks of alcohol. Beliefs that may promote risk denial were frequent (e.g. 72% agreed that soda and hamburgers are as bad as alcohol for your health). Both risk denial and risk relativization scores were higher among men, older respondents and those of low socioeconomic status. The probability of daily drinking increased with the risk relativization score and that of HED with both scores.

Conclusions
Beliefs that can help people to deny the cancer risks due to alcohol use are common in France and may exist in many other countries where alcoholic beverages have been an integral part of the culture. These results can be used to redesign public information campaigns about the risks of alcohol.


Phenylketonuria is the most common, inherited aminoacidopathy associated with brain injury. To date, no study has focused on the neuropathology of the genetic mouse model of phenylketonuria, BTBR-Pah enu2 . We examined dendritic spines and synapses in the CA1 and prefrontal cortex among the wild-type, heterozygous, and BTBR-Pah enu2 mice. A reduced density of dendritic spines, a shortened length of the presynaptic active zone, a widened synaptic cleft, and decreased thickness of postsynaptic density were revealed in BTBR-Pah enu2 mice. Meanwhile, the phosphorylation at Thr286 of Ca2+/calmodulin-dependent protein kinase II&agr; was alerted in BTBR-Pah enu2 mice. These findings revealed that phenylketonuria-related brain impairment is accompanied with abnormalities of dendritic spines and synapses. The dysfunction of Ca2+/calmodulin-dependent protein kinase II&agr; may result in an impaired synaptic function.


Recent research of Cretaceous black flysch of the Raca Unit tentatively named as the "Gault Flysch" enabled to extend the upper range of this formation upward to the early part of the Turonian. Relatively low tectonically disturbed section through the "Gault Flysch" near Bila in the Moravskoslezske Beskydy Mts. provided agglutinated foraminifera of following levels: ?Lower Cretaceous (without significant fauna), Albian-Cenomanian (Plectorecurvoides alternans Zone), Turonian (with Uvigerinammina praejankoi). Overlying Kaumberg Formation contains Turonian assemblage with Uvigerinammina praejankoi and U. cf. jankoi. The evidence of the Turonian in the "Gault Flysch" opens the question of simultaneous co-existence of the black flysch and variegated beds facies within the Raca Unit.


Refugee must be protected by anything necessary. There are instruments in this world created to protect the refugee such as International Organisations and Internasional Conventions. By these kind of instruments, the refugee can savely asking for asylum to any country in the world. The problem is, there are still many countries that not willing to accept the refugee. Many of the refugees got them self stranded and got separated from their family because of the closing of the countries border. That kind of things just won't stop the refugees to cross the border, even if they had to face the border's security. So what is the reason of those countries whose closed their border for rejecting the refugees? In The 1951 Refugee Convention, there is a "non-refoulment" principle which prohibit any countries to do any "refouler" things to the refugee. The reason for those countries to reject the refugees was related to their countries security. They afraid that the Bom Tragedy by the middle east people will after them either if they gave the permission to the refugees for entering their country. They are willing to protect their own people from anything that could put their life in danger


—We describe the optical, mathematical and compu- tational foundations for a new class of lensless, ultra-miniature computational imagers and image sensors. Such sensors employ phase gratings that have provably optimal optical properties and are integrated with CMOS photodetector matrices. These imagers have no lens and can thus be made extremely small ( ∼ 100 µm ) and very inexpensive (a few Euro cents). Because the apertures are small, they have an effective depth of field ranging from roughly 1 mm to infinity. The grating acts as a two-dimensional visual "chirp" and preserves image power throughout the Fourier plane; thus the captured signals preserve image information. The final digital image is not captured as in a traditional camera but is instead computed from raw photodetector signals. The novel representation at the photodetectors demands powerful algorithms such as deconvolution, Bayesian estimation, or matrix inversion with Tikhonov regularization be used to compute the image, each having different bandwidth, space and computational complexities for a given image fidelity. Such imaging architectures can also be tailored to extract application-specific information or compute decisions (rather than compute an image) based on the optical signal. In most cases, both the phase grating and the signal processing can incorporate prior information about the visual field and the imaging or estimation task at hand. Our sensor design methodology relies on modular parallel and computationally efficient software tools for simulating optical diffraction, for CAD design and layout of gratings themselves, and for sensor signal processing. These sensors are so small they should find use in endoscopy, medical sensing, machine inspection, surveillance and the Internet of Things, and are so inexpensive that they should find use in distributed network applications and in a number of single-use or disposable applications, for instance in military, hazardous natural and industrial conditions.


In recent years we have witnessed a dramatic increase in the volume of electronic and digital information that has been produced and as a result we feel increasingly overwhelmed by the amount of digital information that needs to be managed. This paper describes a Web-based personal digital library system, myPDL, which was designed and developed to allow individual users to create, store, organize, and retrieve their own personal digital information collections. The major distinctions between the developed tool and digital libraries in general were that major considerations were put on the functionalities of user customization and user personalization


*† Recent military actions have demonstrated the need for addressing time-sensitive and time-critical targeting. The capabilities of precision guided munitions and the further development of strike warfare platforms and tactics portend a huge increase in effectiveness and lethality of air operations and achieving the vision of the US Air Force's Global Strike Task Force concept. To fully realize the benefits of these strike capable assets and to address the challenges inherent in time-sensitive targeting, decision support systems are needed to assist warfighters in optimal allocation and near real-time re-deployment of air assets, and to support predictive battlespace awareness. While meeting a specific operational need, additional benefits can accrue through the employment of such decision support systems for virtual and constructive simulation based training, experimentation, and Command and Control (C2) system evaluation and acquisition. Here, we detail a Software Toolkit for Optimizing Mission Plans (STOMP). STOMP integrates a genetic algorithm-based mechanism to rapidly generate, analyze, and visualize mission plans in tandem with software interoperability to provide the requisite interface and connectivity with Air Force C2 systems and synthetic battlespace environments.


Karyotypes of human metaphase chromosomes are used to detect genetic defects like deletions or translocations. For these investigations the chromosomes are treated by the trypsin-Giemsa protocol, resulting in a typical banding pattern. These patterns are investigated using conventional light microscopy. Because of the diffraction limit, even the smallest visible band contains ∼1 million base pairs. We want to improve resolution by using bright-field scanning near-field optical microscopy (SNOM). Images of trypsin-Giemsa-treated chromosomes are presented and compared with conventional light microscopic, scanning force and scanning fluorescence near-field optical microscopic data. For fluorescence investigations, the chromosomes were stained using propidium iodide. To our knowledge, it is the first attempt to investigate G-banded chromosomes by SNOM.


Many research efforts focus on the definition of models and techniques to simulate and predict the reaction of individuals face to an information. In this context, great benefits could derive from the exploitation of individual's personality and cultural values in the diffusion model process. In this paper we describe a new architecture for agent-based model using the DEVS (Discrete EVent System Specification) framework and show how this architecture is flexible and can serve to simulate the dissemination process. In more details, we define a set of models of individuals characterized by a set of state variables to represent the behavior of an individual and the mesh between the individuals within a multi-layer social network. Then, we introduce the platform architecture, specifically designed to simulate message propagation in a multilayer network. In the end, a military scenario of message diffusion during a stabilization phase is used to test our DEVS models on the platform and the relevancy of the simulation results.


CyberGIS is an interdisciplinary field combining advanced cyberinfrastructure, geographic information science and systems (GIS), spatial analysis and modeling, and a number of geospatial domains to improve research productivity and enable scientific breakthroughs. It has emerged as a new-generation GIS that enables synergistic advances in data-driven knowledge discovery, visualization and visual analytics, and collaborative problem solving and decision making. This paper describes a cutting-edge cyberGIS software environment from a system perspective. Two case studies focus on elucidating BioScope: a data-driven and computationally intensive cyberGIS application for bioenergy supply chain optimization, and MovePattern: interactive and multi-scale visual analytics for complex and massive movement data extracted from the Twitter steaming application programming interfaces. These studies demonstrate widely accessible capabilities of cyberGIS for resolving the variety, velocity, and volume of spatial big data to enable unprecedented data-intensive knowledge discovery.


An experimental arrangement is described which was set up to measure the energy loss spectra of electrons which have passed through thin specimens in the electron microscope. It consists of a nondispersive filter lens which rejects electrons of less than a certain energy, determined by the voltage of the central electrode. By modulating this voltage with a small ac component and measuring the resulting modulation of the transmitted beam, the apparatus can be used as an energy analyser. In this paper, the process of `differentiation by modulation' is reviewed and the effects of using different waveforms and frequencies examined. Also discussed are high-voltage insulation and breakdown in vacuum, the effect of focusing the beam on the phosphor (which was used as the electron detector), and limitations upon possible sweep speeds. A novel feature of the system is a 2 kHz optical link used to supply a synchronizing signal to the high-voltage line. The energy resolution of the system comes close to the theoretical minimum of about 1?5 eV. At low accelerating voltages output noise is almost entirely shot noise, but above 60 kV microdischarges increase the noise level substantially. Noise from these two sources limits the usefulness of the system for measuring low currents.

Neanderthal blueprint Scientists have deciphered the sequence of the Neanderthal genome, based on DNA extracted from bone fragments of between 40 000 and 70 000 years old, from a range of sites across Europe (Steve Connor, The Independent, 13 February 2009). In a project that took two years to complete, a team of scientists led by Professor Svante Paabo of Leipzig's Max Planck Institute deciphered 60 per cent of the genome from over 70 individual bones—and then used it to calculate the rest. Usually depicted as brutish (Fig. 1), the results of this research show that Neanderthals are closer to modern humans than we might want to imagine. According to Professor Paabo, Neanderthal DNA falls comfortably within the range of variation possessed by modern people—making them genetically difficult to distinguish.


A convergent approach provides a convenient access to synthetically and biologically useful 3,4-disubstituted 5-hydroxyindoles. The one-pot procedure uses microwave heating to initiate an intramolecular [4 + 2]-cycloaddition of an alkynol segment onto a furan followed by a fragmentation, aromatization, and N-Boc deprotection cascade. Yields range from 15 to 74%, with aromatic substituents providing better conversions. 4-Trimethylsilylated analogues undergo a 1,3-silatropic rearrangement to give the O-TMS ethers.


The correlation between spectral response (relative reflectance) from soils and the organic matter and clay content was investigated. Statistical models were developed that can utilize data obtained from an airborne multispectral scanner to estimate the quantity of organic matter and clay in the surface soil. These models can be implemented on a digital computer to produce maps delineating soils with different levels of organic matter or clay content.


Trapped image guides are analyzed using a new method. The results agree much better with experimental data than those previously derived from a simple effective dielectric constant approach.


In these lectures we discuss examples that are relevant to two questions in the theory of singular integrals. The first question is the L boundedness of the maximal operator formed by dilates of Mikhlin-Hörmander multipliers, while the second concerns the L boundedness of a well-known object, the classical L-bounded Calderón-Zygmund homogeneous singular integral associated with an integrable function on the sphere that is very rough.


To compare medium-term outcomes of active surveillance (AS) for men with favourable risk International Society for Urologic Pathology (ISUP)-2 prostate cancer (PCa) to a pair matched group of men with ISUP-1 PCa. This was a retrospective analysis of prospectively collected data from a single institution clinical outcomes registry, using propensity score matching. Men enrolled on AS with favourable risk ISUP-2 PCa with minimum 5-year follow-up were 1:2 propensity score matched to men with ISUP-1 disease. We assessed rates of progression to treatment, metastatic disease, adverse surgical pathology and overall survival. Fifty-five ISUP-2 patients were matched to 105 ISUP-1 patients by propensity score. Median follow-up was 81 months (interquartile range (IQR), 61–109 months). Fifty-seven per cent in the ISUP-1 group progressed to treatment versus 58% in the ISUP-2 group (KM log rank p = 0.24). Estimated 1-, 2- and 5-year progression free survival rates were 93%, 60% and 33% for ISUP-1 patients and 94%, 63% and 16% for ISUP-2 patients, respectively. No patient from either group died of PCa. There was no statistical difference in rates of adverse pathology or metastatic disease between ISUP-2 and ISUP-1 patients on AS. AS for carefully selected men with favourable risk ISUP-2 disease appears safe, with similar oncologic outcomes to men with ISUP-1 disease. Level 2b.


The invention relates to curable composition comprising a curable component and an m-hydroxybenzene derivative of the general formula (I): wherein Y is a carboxyl group, a carboxylate group or a linear or branched, optionally with hydroxyl groups, amino groups, carboxyl groups and / or carboxylate groups and R 1, R 2 and R 3 independently of one another identical or different and represent hydrogen or a hydroxyl group and R 1 and R 3 are not simultaneously a hydroxyl group; with the proviso that, where the curable component is a thermosetting component of a multicomponent system, epoxy-based, the curable composition is free of transition metal oxides of copper and zinc and that where the curable component is a thermosetting component, epoxy-based , it is not a self component. The invention further relates to the use of the m-Hydroxybenzenderivate as aging inhibitors in coating compositions and adhesives, and a process for coating or bonding of substrates.


An electrolyte cation additive strategy provides a versatile route for developing high‐energy and long‐life aqueous zinc‐ion hybrid capacitors. However, the mechanisms of energy storage and Zn anode protection are still unclear in Zn‐based systems with dual‐ion electrolytes. Here, a dual charge storage mechanism for zinc‐ion hybrid capacitors with both cations and anions adsorption/desorption and the reversible formation of Zn4SO4(OH)6·xH2O enabled by the Mg2+ additive in the common aqueous ZnSO4 electrolyte are proposed. Theoretical calculations verify that the self‐healing electrostatic shield effect and the solvation‐sheath structure regulation rendered by the Mg2+ additive account for the observed uniform Zn deposition and dendrite suppression. As a result, an additional energy storage capacity of ≈50% compared to that in a pure 2 m ZnSO4 electrolyte and an extended cycle life with capacity retention of 98.7% after 10 000 cycles are achieved. This work highlights the effectiveness of electrolyte design for dual‐ion carrier storage mechanism in aqueous devices toward high energy density and long cycle life.


The process of gas molecules, which stick and escape over a solid surface, is analyzed by numerical simulation. The history of energy of gas molecule sticking on clean surface is compared with that on the surface with adsorbed gas molecules. The energy and velocity distribution when gas molecule escape from surface is almost same as the Boltzmann distribution, but the average of them differs from the wall temperature. Some group of these escaping molecules are not in equilibrium with the surface. The length of sticking time is important in the process of escaping from the clean surface. Also, the molecule with which the escaped molecule contact at last is the important parameter of those differences on the adsorbed surface.


The change in the ice conditions in the Arctic made it possible to study vast areas of the shelf by geophysical methods, including electromagnetic ones. The structure of the Arctic shelf subsea permafrost differs from the well-studied continental permafrost due to its accelerating degradation caused by the action of near-bottom waters. The features of the subsea permafrost are reflected in the electrical conductivity of rocks, since this property is sensitive to parameters such as the pore fluid salinity and pore ice/gas hydrate content. The capabilities and resolution of various marine electromagnetic technologies are analyzed, especially in application to the Arctic shelf exploration, an area with the sea depths of up to 100 m, where relict permafrost may exist.
