Rationale The evidence of intravenous thrombolysis in patients with not clearly disabling minor stroke (low National Institutes of Health Stroke Scale of 0–5) is still insufficient. Recent early terminated PRISMS trial could not provide definitive conclusion, although suggesting the similar functional outcome between alteplase and aspirin groups. Recent two clinical trials provide a definitive evidence for the superiority of dual antiplatelet to mono-antiplatelet in minor stroke. However, the efficacy and safety of dual antiplatelet vs. alteplase in the treatment of acute minor stroke are not known. Aim To explore the efficacy and safety of dual antiplatelet with aspirin and clopidogrel vs. alteplase in the treatment of acute minor stroke. Sample size estimates A maximum of 760 subjects are required to test the non-inferiority hypothesis with 80% power according to a one-sided 0.025 level of significance, stratified by age, diabetes, time from onset to treatment, stroke etiology, degree of vascular stenosis, location of index vessel. Methods and design ARAMIS is a prospective, randomized, open label, blinded assessment of endpoints (PROBE) and multicenter clinical trial in China. The subjects are randomized to the control arm (intravenous alteplase with standard dose of 0.9 mg/kg, followed by guideline-based treatment 24 h after thrombolysis) or the experiment arm (clopidogrel: loading dose of 300 mg on the first day, followed by 75 mg daily for 10–14 days; aspirin: 100 mg on the first day, followed by 100 mg daily for 10–14 days; after the combination, antiplatelet will be given based on guideline till 90 days). Study outcome The primary efficacy endpoint is favorable functional outcome, defined as a mRS 0–1 assessed at 90-day post-randomization.


Voltage regulators (VRs) powering microprocessors face stringent requirements on size; response; and efficiency. Presently, buck converters are used exclusively as VRs for their simple, well-understood behaviour despite their many shortfalls; while more suitable resonant converters are overlooked due to size and performance issues associated with their control methods. In this paper, variable frequency pulse density modulation (VF-PDM) control of the series resonant converter (SRC) is presented to enable resonant converter benefits to be realized in VR applications. It achieves efficient multimegahertz switching frequency, ultra-fast transient response with minimal filter capacitance, and is inherently stable. It will be shown that the SRC under VF-PDM can outperform a two phase buck converter in every aspect including size, speed, and efficiency.


Summary Sweet corn in 2018 was affected by irrigation, plant population, and a fungicide applied for stomatal control. Even though measured stomatal conductance was unaffected and no disease pressure was noted, applying fungicide at V6 more than doubled the number of harvested ears per acre and per plant, but an additional application at R1 did not increase harvested ears. Applying 1 inch of irrigation at the VT growth stage resulted in approximately 20% greater number of harvested ears per acre and ears per plant, but did not increase fresh weight. Under these dry conditions, increasing plant population tended to decrease harvested ears per acre and ears per plant, especially when no fungicide was applied or with no irrigation.


More than 30 years have passed since first calls to see accounting as social and institutional practice (Burchell et al., 1980; Hopwood, 1987; Hopwood & Miller, 1994). During these years, a sig ...

It mentions that he concentrated upon the Officers Training Corps in lieu of his history studies. It states that he was a Junior Second Lieutenant in World War I. It mentions that as a result of poor combat living conditions he contracted a bad case of enteritis and was assigned as Assistant Adjutant to the Reinforcement Depots at Rouen.


Soil bacterial communities are different in various agricultural ecosystems. To assess the differences in soil bacterial communities between organic and conventional farming modes, high-throughput Illumina MiSeq sequencing was conducted. A total of 3, 919 operational taxonomic units
 were identified and classified as 26 phyla, 42 classes, 78 orders, 120 families, 281 genera, and 340 known species. The histogram of the microbial species distribution at genera levels showed that Massiliaand Lysobacter increased quickly in soil under organic farming mode. Analysis
 of soil bacterial diversity showed that the soil under the organic farming had a greater bacterial diversity. Linear discriminant analysis effect size analysis showed that the major bacterial groups identified in the soil sample CK1 (2015.4) and CK6 (2017.10) under conventional farming mode
 were largely different from those in the soil sample 06 (2017.10) under organic farming mode. Redundancy analysis demonstrated that available nitrogen was the most important factor regulating bacterial composition under the organic farming mode. Massilia, Pseudomonas, Lysobacter and
 Pseudarthrobacterabundances showed a strong positive correlation with the content of available nitrogen. The results provided an important reference for the utilization of soil microorganisms under the organic farming mode.


: According to the National Health Survey (2014), carried out by the Ministry of Health in partnership with the IBGE, it is estimated that Diabetes Mellitus affects nine million Brazilians. In order to facilitate the diagnosis within the scope of the research, the possibility arose of using saliva as a possible indicator for the diagnosis of diabetics and diseases of the oral cavity. The objective of this work was to screen individuals who attend a charity institution in Santana de Parnaíba, from December 2019 to December 2021, to investigate the presence of glucose and changes in the oral cavity. The methodology was semi-quantitative, in saliva samples, performed by reagent strip. 229 individuals (84.3%) with positive nitrite were screened; 86 (32%) leukocytes; 168 (62.6%) blood; 141 (52.6%) protein and glucose 2 (0.74%). The salivary examination demonstrated efficiency in the detection of elements indicating oral alterations. Based on the data, it is suggested as an alternative methodology for screening for oral diseases. However, this methodology did not present results that proved sensitivity for the detection of glucose by saliva.


The Soldier is a sonnet written in 1914 by Rupert Brook, a British war poet. The paper aims at analyzing the poem by applying M.A.K. Halliday's Systemic Functional Linguistics (SFL) as a theoretical framework. The study mainly adopts a qualitative methodology to analyze the text by text linguistics. However, the quantitative methodology is also used to calculate the proportions of each metafunctional process in this poem. The main findings of this paper are: 1) Topic theme: the themes of the poem are I, dust, England, this heart, et., which show the soldie''s love and gratefulness for England; 2) The focus of tense: The Soldier starts with a conditional clause and then uses present and past tense to create a context as if he was depicting a real external world instead of an imagination from the inner world. 3) Patterning and re-patterning: The patterning analysis shows the soldier in the poem emphasizes his motivation for sacrificing and spreading the precious things in England who had brought him up. The paper concludes that The Soldier shows a strong sense of patriotism, which might be an approval for the former literary studies of this poem from linguistic aspects.


Extracting minimal functional dependencies (MFDs) from relational databases is an import database analysis technique. With the advent of big data era, it is challenging to discover MFDs from big data, especially large-scale distributed data stored in many different sites. The key to discovering MFDs as fast as possible is pruning the useless candidate MFDs. And in most existed algorithms, it usually prunes candidate MFDs from top to bottom or from bottom to top. We present a new algorithms FastMFDs for discovering all MFDs from large-scale distributed data both from top to bottom and from bottom to top in parallel. We experimented our algorithm in real-life datasets, and our algorithm is more efficient and faster than the existed discovering algorithms.


Barium present at the 1 to 20 p.p.m. level in calcium carbonate is separated from the calcium matrix by co-precipitation on a lead sulphate carrier. The lead sulphate-barium sulphate precipitate is dissolved in an ammoniacal solution of ethylenediaminetetraacetic acid disodium salt and the barium in the resulting solution is determined by atomic-absorption spectrophotometry by using a nitrous oxide-acetylene flame and the atomic line at 553·6 nm.The method overcomes interferences that occur in the atomic-absorption spectrophotometric determination of barium in the presence of calcium.


The paper studied the survival rate and keeping rate of forestation by adopting sowing seedling and cutting seedling of Calligonum rubicundunm at spring and autumn(raining season).In the meantime,the rejuve-nation measures of stumping the wind protection sand fixing forests of 4 years-old Calligonum rubicundunma in different season and with different stubble height were also studied in this paper.The results showed: in Spring,the forestation with sowing seedling was the best,particularly it can improve the survival rate of forestation by adopting dipping root in mud;stumping is an effective way to promote the rejuvenation of Calligonum rubicun-dunm;the amount of new branches and growth increment of plant in April were more than in June;with the in-creasing of stubble height at 10~40 cm stumping scope,the amount of new sprouting branches also increased.

The invention discloses a viewing field amplifier of a multi-GigE (Gigabit Ethernet) camera measuring system, and an application of the viewing field amplifier. The viewing field amplifier is characterized in that an inverted-U-shaped camera support is arranged between a pair of longitudinally parallel linear guide rails; a GigE camera is fixedly arranged on the inverted-U-shaped camera support; the inverted-U-shaped camera support can drive the GigE camera to make longitudinal linear motion on the linear guide rails; a cross rod support is arranged between the linear guide rails horizontally; a reflector group is arranged on the cross rod support; the GigE camera uses the reflector group to obtain a measured viewing field on the side of the GigE camera; and the cross rod support can drive the reflector group to make longitudinal linear motion on the linear guide rails. The reflector group is adopted, and the viewing field on the side of a lens of the GigE camera can be transmitted to the lens of the GigE camera, so that unidirectional movement of the GigE camera is reduced; the measuring precision is improved; and the measuring time is shortened.


Costa H., Gonçalves Veiga L. and Portela M. Interactions in local governments' spending decisions: evidence from Portugal, Regional Studies. This paper aims to analyse the degree of interaction between Portuguese municipalities' expenditure levels by estimating a dynamic panel model, based on jurisdictional reaction functions. The analysis is performed for all 278 Portuguese mainland municipalities from 1986 to 2006, using alternative ways to measure neighbourhood. Results indicate that local governments' spending decisions are significantly and positively influenced by the actions of neighbouring municipalities. Attempts to identify the sources of interaction allow it to be concluded that they are due to spillovers that require coordination in expenditure items and to mimicking behaviour possibly to attract households and firms.

For centuries the mechanics of the money system have remained hidden from the prying eyes of the populace. Its impact, both on a national and international level, is perhaps unsurpassed. In fact, the monetary system provides the mainstay for international dominance and national control. Is hard without crisis to change economic or political system but often those who are set up to defend the interests of the people and state as a whole, authorities, reject what doesn't fit well with what they like. Today, as these mainstays are being shaken by crises, the need for open and honest dialogue on the future system is at its highest level.


There are three codes in Galileo system:the Coarse Access (C/A) code,the Precise (P) code,the M code. The key of Galileo System is the Coarse Access (C/A) code. Although the accuracy of the C/A code is lower than the Precise (P) code,the format of C/A code is open. But the Pcode isn't open to the civil usage,and the Pcode acquisition also establishes the earlier C/A code acquisition. Therefore it aims at the research of the C/A code. Simulate the C/A code generation,modulation and acquisition. The acquisition scheme based on FFT is also provided and improved this method,reduced the acquired time. The performance at the noisy situation is very well which used improved way,and it also provided helpful information for the Pcode acquisition.


Trees of the olive (Olea europaea L.) cultivar Carolea grown in Calabria (Italy) in three sites with different main climate traits (temperatures, rainfall, Growth Degree Days seasonal variations) were studied for three years to see the ripening time course and quality of the oils. The optimal harvesting time for obtaining the best-quality olive oils was defined for each site. The effect on quality indexes of three harvesting periods was also considered, linking this to the observed various thermal regimes. The different climates largely affected the growth and the development of fruits and the quality of obtained oils. Lower temperatures and higher rainfall slow down fruit growth and development and delay ripening. Olive oils of good quality (free acidity, fatty acid composition, antioxidant components and oxidative stability were obtained in the site with lower temperatures and higher rainfall when fruits were still yellow-green ripe and had a detachment index between 1.9 and 1.5. Climate change, evidenced by rising temperatures, led to the movement of olive groves from the high-temperature coastal plain to the intern foothills.


Applications to record the presence, is an simple application, but have a huge impact, because as it would related to the performance of a person in companies, therefore the record of presence must be able to provide correct information on each user's information. The aim of this study is to find the affected between information quality , system quality and service quality to user satisfaction, partially and simultaneously. The method of this study used multiple regretion, and the result is information quality , system quality , service quality has a positive influence simultaneously on user satisfaction. Information quality does not have influence to user satisfaction , and so the System quality does not have influence to user satisfaction, but Only quality of service has influence the user satisfaction.


This paper proposes a novel three-dimensional (3D) non-stationary irregular-shaped geometry-based stochastic model (IS-GBSM) for beyond fifth-generation (B5G) and sixth-generation (6G) vehicle-to-vehicle (V2V) millimeter wave (mmWave) massive multiple-input multiple-output (MIMO) channels. By distinguishing dynamic clusters and static clusters, the proposed IS-GBSM for the first time explores the impact of vehicular traffic density (VTD) on channel statistics in B5G/6G V2V mmWave massive MIMO scenarios. Furthermore, a novel method is developed to model the channel space-time-frequency non-stationarity. In the developed method, dynamic/static correlated clusters are first generated by an improved $K$ -Means clustering algorithm. Then, by employing a birth-death process based on correlated clusters, the consistency in birth and death between dynamic/static correlated clusters during time-array evolution is modeled. Key channel statistical properties, e.g., space-time-frequency correlation function (STF-CF) and Doppler power spectral density (DPSD), are derived. Simulation results demonstrate that the space-time-frequency non-stationarity is captured and the influence of VTDs on channel statistics is explored. Finally, the close agreement is achieved between simulation results and measurements, verifying the utility of proposed IS-GBSM.

LAP, the Linux Application Platform, is a Linux emulation package for BSD/OS which uses a "little language" [Salu98] to describe transformations from Linux data types and values to BSD/OS data types and values, and vice versa. The little language simplifies and regularizes the specification of transformations, making the emulation easier to maintain. This paper describes the language and its place in the framework of LAP.


To study the effects of microorganism agent on saline soil and choose salt tolerant alfalfa cultivars,the effects of microorganism agent on soil desalination rate and alfalfa growth were studied by conducting a pot experiment under different salt stress levels,and the interaction between microorganism agent,alfalfa varieties and salt stress degree were also discussed.The results showed that the microorganism agent had a significant effect on increasing the soil desalination rate,and the soil desalination rate in 0-20 cm soil layer under applying microorganism agent treatment was increased by 9.04% compared to that of no microorganism agent treatment.Salt stress significantly affected alfalfa biomass,which represented that alfalfa biomass was decreased with the increase of salt stress degree.The three alfalfa cultivars had significant differences in salt tolerance,and the sequence from high to low was Laobo,Baoding and Sandeli.Consequently microorganism agents and salt tolerant alfalfa cultivars have good effects on soil salinity control and growth of alfalfa.


With the improvement of chip debugging technology performance, the chip physical attack technology has also been developed rapidly. At present, the active shield has become the main protection against physical attacks on the chip. In this paper, for the shortcomings of digital shield detection circuit which cannot resist rewiring attack, we propose a scheme to collect some channel signal propagation delay to detect whether the shield is under rewiring attack on the basis of random code stream detection circuit. The scheme is applicable to parallel multi-channel shields. Random sequences is passed to the inner channels and pulse signals is passed to the outer channels, and the random sequence is compared in the detection circuit to determine whether the random sequence is consistent and the pulse signal width is within the error range, so as to determine whether the shield is damaged or modified. The final experiment shows that the scheme has the characteristics of simple digital type detection circuit, low overhead, after the implementation in smic0.18um process, the area of 25766um2, power consumption of 1.6639mw, can identify more than 8% of the shield failure area of rewiring attacks, to make up for the inherent parametric type detection circuit complexity defects.


The photograph, which was taken a week after the above description was made, leaves the diagnosis in little doubt. For purposes of comparison I gave the smaller tumour an exposure of X-rays 5H unfiltered, using a spark-gap of 5i in., and Dr. Guy Whorlow kindly gave the larger tumour an exposure of |̂ H.E.D., using a 14i in. spark-gap and a filter of 0-5 mm. of zinc. At the end of three weeks both tumours had disappeared, and ia each case there remained a clean healing ulceration about f in. in diameter. The larger tumour had responded relatively more quickly to the more penetrating type of ray, but the advantage was not in proportion to the extra cost of the treatment. Subsequently the greater part of the surface of the body received a dose of 4H filtered through 0*5 mm. of aluminium. This stopped the desquamation but smooth red areas remained. It did not, unfortunately, seem to influence the appearance of fresh tumours, for several small ones were seen, four weeks later, on the areas exposed.

The hyaline membranes are considered as a stadium of the absorption or the concentration in pulmonary edema.4. Pulmonary edema and pneumonia are closely interrelated even in the animals.5. Pulmonary edema is a cause of death in the animals, just as atelectasis is significant in the human newborn infant.6. Pulmonary edema of human newborn infant should be carefully observed in the mesenchyma of the lungs.


This article focuses on the issue of nobility as a memorial practice in the premodern era. It challenges the popular assumption that the nobility was largely defined by a shared social memory, that is, the collective remembering of which lineages were considered to have noble blood and who had supposedly mastered the noble lifestyle since time immemorial. In this contribution, we argue that there was a structural field of tension between this noble culture of remembrance and the considerable rate of renewal in the social composition of the nobility. Noble ranks were constantly being replenished by newcomers, who had to inscribe themselves in collective consciousness as a noble lineage. The case-study of Nicholas Despars, a sixteenth-century chronicler who belonged to a recently ennobled family of Bruges spice merchants, shows that historiographical writings were often used to influence the public perception of such families. Because this functional approach of premodern elites towards their own past often included the manipulation of archival records, the memorial practices of the sixteenth-and seventeenth-century nobility have led to a distorted view of important aspects of late medieval society in recent historiography.


Maneuvering target detection is a challenging task for radar due to its maneuverability and weak energy. Long-term coherent integration can remarkably increase signal energy to improve the target detection ability. Unfortunately, high velocity and acceleration of the target will produce linear range migration (LRM), quadratic range migration (QRM), and Doppler frequency migration (DFM), which seriously degrades the coherent integration gain and further deteriorates target detection performance. To solve this problem, a method based on second-order Keystone transform (SKT) and Lv's distribution (LVD), also combined with Radon Fourier transform (RFT), i.e., SKTLVD, is proposed in this paper. The LRM is firstly corrected by using RFT. Then, the SKT is employed to remove QRM. Finally, LVD is utilized to eliminate the DFM and achieve coherent integration. Compared with several representative methods, the SKTLVD consumes low computation and obtains good target detection performance, striking a balance between computational cost and target detection ability. Numerical simulations and real measured radar data demonstrate that the proposed method can obtain considerable coherent integral gain under acceptable computational complexity.


Voice assistant systems (e.g., Siri, Alexa) have attracted wide research attention. However, such systems could receive voice information from malicious sources. Recent work has demonstrated that the voice authentication system is vulnerable to different types of attacks. The attacks are categorized into two main types: spoofing attacks and hidden voice commands. In this chapter, how to launch and defend such attacks is explored. For the spoofing attack, there are four main types, such as replay attacks, impersonation attacks, speech synthesis attacks, and voice conversion attacks. Although such attacks could be accurate on the speech recognition system, they could be easily identified by humans. Thus, the hidden voice commands have attracted a lot of research interest in recent years.


We evaluate the quantum corrections of the Einstein-Hilbert action with boundaries in the 2 + ǫ dimensional expansion approach. We find the Einstein-Hilbert action with boundaries to be renormalizable to the one loop order. We compute the geometric entropy beyond the semiclassical approximation. It is found that the exact geometric entropy is related to the string succeptibility by the analytic continuation in the central charge. Our results also show that we can renormalize the divergent quantum corrections for the Bekenstein-Hawking entropy of blackholes by the gravitational coupling constant renormalization beyond two dimensions.


This work presents experimental mixing properties, hE and vE, at several temperatures and the isobaric vapor–liquid equilibria (iso-p VLE) at 101.32 kPa for four binaries containing pentane and four alkyl (methyl to butyl) methanoates. Particular conditions are established to work with these solutions with highly volatile compounds, especially for the case of methyl methanoate + pentane system, for which a continuous feeding device is designed and constructed for measuring the densities. The mixing processes of the compounds chosen give rise to high values for the excess properties and also for the activity coefficients, since in addition to the known effects that arise in the binaries ester + alkane, in this case the associative effects caused by the HCOO– group, which diminish with increasing methanoate chain length are also relevant. The change in temperature produces slopes of opposite signs for the mixing properties, being ( ∂vE/∂T ) p < 0 and ( ∂hE/∂T ) p > 0. The systems comprised of methyl and ethyl methanoate with pentane present azeotropes with coordinates (xaz,Taz/K) situated at (0.558, 293.9) and (0.218, 306.5), respectively. The estimation of these coordinates and the iso-p VLE by the UNIFAC method are acceptable E but do not give good predictions of the h even less so for the LLE of the methyl methanoate + pentane system. For this binary, experimental data of all the properties are correlated with a mathematical procedure described using two models, one developed by us, and an extended form of the NRTL model. The latter does not represent the LLE data but shows the properties of isobaric equilibria, with acceptable results, while the proposed model, in addition to representing the binodal curve, gives a good representation of the vE and of these properties derived from excess Gibbs function.


Objectives In this study, for the purpose of improving 26 4th graders' English learning interest, a homeroom teacher conducted an action research study and helped their mobile-app-based English learning and her adviser supervised the teacher to conduct the research study successfully, according to qualitative research tradition. Although many theorists and scholars propose promising effects of mobile-app-based English learning there is not much mobile-app-based English learning research conducted with primary school students and teachers at public primary school settings. This is an action research study to fill the gap in the previous studies.
Methods During the spring semester of 2022, 26 elementary school students in a southern province performed mobile-app-based English learning activities with their homeroom teacher in a 30-minute morning-class session and in a 40-minute club activity session. Teacher observation reports, survey results and interview data are collected before, in or after the mobile-app-based English teaching/learning class.
Results The first result is that almost all of the 26 students liked the English learning activity of singing English songs using YouTube app. As for the second result, among the four English learning apps applied in the study, most of the students liked the Dino Buddies series of the Little Fox app and the Kahoot word quiz app the most, and low-English-learning-autonomy students liked the 'FunEasyLearn' English app the most. The third result is that all 26 students' interest in learning English improved while participating in the study, with varying degrees of improvement. The fourth result is that the preference for mobile-app-based English learning activities varies greatly by student according to the level of English-learning interest improvement.
Conclusions The results of the study showed that 26 students who conducted English learning using mobile apps for one semester developed interests in learning English and that they all had various preferences for mobile-app-based English learning activities. Based on the study results, it can be predicted that the learning effect will be maximized if mobile-app-based English teaching is carefully planned and implemented according to the characteristics, autonomy, personality, and English proficiency levle of each student as a learner. In particular, when carrying out mobile-app-based English teaching for students with low autonomy, it would be very helpful if an individual learning helper or an assistant teacher helps their learning. It seems that further research is still needed to know how to implement mobile-app-based primary English education for Korean learners.


Purpose . The aim of the work is to study the influence of longitudinal quasistatic tensile and compressive forces in gondola cars arising at stationary and transient modes of train movement on their main dynamic indicators and interaction indicators of rolling stock with a rail track, taking into account the possibility of speed increasing. The relevance of this study is related with the need to control the longitudinal forces arising during stationary and transient modes of train movement, with increasing speeds, masses and lengths of trains, especially freight ones, increasing the locomotives` power. Methodology . The main method for studying the dynamic loading of a gondola car on typical three-element bogies is mathematical and computer modeling of the interaction of rolling stock and track structure based on the model of spatial vibrations of freight cars` couplings. In a theoretical study, the influence of quasistatic longitudinal tensile and compressive forces is considered depending on the change in speed and the force value on the tension of 1 MN; 0.5 MN; 0 and before compression of 0.5 MN; 1 MN. Findings . As a result of theoretical studies and after modeling, taking into account the processes of oscillation of gondola cars under the action of quasistatic longitudinal forces limited by norms to ± 1MN (100 tf), the dependencies of the main parameters normalized by technical documentation are obtained taking into account the value of the movement speed. Originality . The influence of longitudinal compressive and tensile forces on the dynamic loading of a freight car is studied in order to solve the problem of forecasting the dynamics of rolling stock, taking into account the value of the speed along curved track sections. Practical value . Application of the results obtained can increase the stability of freight rolling stock and the strength of the railway track, which in turn will remove some existing restrictions on permissible speeds and increase the technical speed of trains. The obtained dependencies of the main normalized indices on the longitudinal quasistatic force will make it possible to predict the development of deviations and prevent their transformation into the dangerous ones for train movement.


Nigerian bank notes like other currencies in the world pass through different hands and have been implicated in the carriage of medically important pathogens. This study was undertaken to determine the types of bacteria present on Nigerian currency in Ile-Ife, Osun State, with a view to determining the potential of naira notes as environmental vehicle for the transmission of potential pathogenic bacteria.  Standard microbiological methods were used to isolate, characterize and identify the bacterial isolates from different banknotes. Disc diffusion method was used to determine the sensitivity of the isolates to ten antibiotics. Representative multiple antibiotic resistant isolates were profiled for plasmid deoxyribonucleic acid (DNA). A total of three hundred and five comprising 216 Gram positive and 89 Gram negative bacteria were isolated from two hundred and five bank notes sampled; naira in mint condition was used as control. Thirteen bacterial genera namely Bacillus, Corynebacterium, Staphylococcus, Lactobacillus, Micrococcus, Aeromonas, C itrobacter, Edwardsiella, Klebsiella, Moraxiella, Pseudomonas, Enterobacter and Proteus were recovered. Resistance to antibiotics was generally high and varied among the isolates. Resistance ranged from 18.18% to 100% in Gram negative bacteria and 26.6% to 100% in Gram positive isolates. Enterobacter sp. and Edwardsiella sp. recovered were 100% resistant to all the antibiotics except septrin. All the isolates were resistant to more than one antibiotic. Multiple antibiotic resistant isolates harboured plasmids of various sizes, ranging from 1,356 bp to 17,367 bp in Gram- positive bacteria and 1815 to 23130 bp in Gram negative isolates. Nigerian currency harboured different types of multiple antibiotic resistant bacteria which can be implicated in human infections; hence constituting a potential public health hazard. Keywords : bacteria, multiple antibiotic resistance, currency, plasmids, pathogens, mint

. We compare Seyfert 2 galaxies(Sy2s) with detected polarized broad emission lines(PBL) with Sy2s without detected PBL and find that the majority of Sy2s without PBL are those sources with less powerful AGN activity, most likely caused by low accretion rates. This implies that the detectability of polarized broad emission lines in Sy2s mainly depends on their central AGN activity in most cases. We also find that Sy2s without PBL follow the exactly same FIR-radio relation as normal and starburst galaxies.


This study analyses and discusses the historiographic construct "modernity" and the problem of its representations and their readings and interpretations. It examines the question based on two exemplifications, with the aid of iconographic sources, attributing to them the function of mimesis of the empirical culture of the school: a) the universal exhibitions (modernity as performance); b) the ambivalences of the modern (dialectical understanding of modernity). It concludes with an attempt at a synthetic closure of a hermeneutic character.


This paper revisits blind source separation of instantaneously mixed quasi-stationary sources (BSS-QSS), motivated by the observation that in certain applications (e.g., speech) there exist time frames during which only one source is active, or locally dominant. Combined with nonnegativity of source powers, this endows the problem with a nice convex geometry that enables elegant and efficient BSS solutions. Local dominance is tantamount to the so-called pure pixel/separability assumption in hyperspectral unmixing/nonnegative matrix factorization, respectively. Building on this link, a very simple algorithm called successive projection algorithm (SPA) is considered for estimating the mixing system in closed form. To complement SPA in the specific BSS-QSS context, an algebraic preprocessing procedure is proposed to suppress short-term source cross-correlation interference. The proposed procedure is simple, effective, and supported by theoretical analysis. Solutions based on volume minimization (VolMin) are also considered. By theoretical analysis, it is shown that VolMin guarantees perfect mixing system identifiability under an assumption more relaxed than (exact) local dominance - which means wider applicability in practice. Exploiting the specific structure of BSS-QSS, a fast VolMin algorithm is proposed for the overdetermined case. Careful simulations using real speech sources showcase the simplicity, efficiency, and accuracy of the proposed algorithms.


The objective of the present study is to extract new information from complex signals generated by Respiratory Inductive Plethysmography (RIP). This indirect cardio-respiratory (CR) measure is a well-known wearable solution. The authors applied time-scale analysis to estimate cardiac activity from thoracic volume variations, witnesses of CR interactions. Calibrated RIP signals gathered from 4 healthy volunteers in resting conditions are processed by Ensemble Empirical Mode Decomposition to extract cardiac volume signals and estimate stroke volumes. Averaged values of these stroke volumes (SVRIP) are compared with averaged values of stroke volumes determined simultaneously by electrical impedance cardiography (SVICG). There is a satisfactory correlation between SVRIP and SVICG (r=0.76, p


Inspired by coarea formula in geometric measure theory, an occupation time formula for continuous semimartingales in $\mathbb{R}^{N}$ is proven. The occupation measure of a semimartingale, for $N\geq2$, is singular with respect to Lebesgue measure but it has a bounded density "transversal" to a foliation, under proper assumptions. In the particular case of the foliation given locally by the distance function from a manifold, the transversal density is related to a geometric local time of the semimartingale at the manifolds of the foliation.


Subclavian artery aneurysm (SAA) only occurs in approximately 0.1% of all atherosclerosis aneurysms. Spontaneous rupture of subclavian artery is an extremely rare phenomenon which can lead to mediastinal hematoma and subsequent cardiac death from multiple complications. Proximal and mid clavicular SAAs have higher incidence of rupture. Thrombo-embolic phenomenon is mostly correlated with distal SAA, but it also occurs in <9% of proximal SAA as well. Therapeutic options of SAA repair are open surgical repair or endovascular treatment. We present a case of spontaneous rupture of subclavian artery aneurysm rupture leading to mediastinal hematoma with hypovolemic shock and death.

Given the Supreme Court's rulings that there is no federal constitutional right to physician-assisted suicide, the locus of legal debate will move to state forums. Courts have more than twenty years' experience in legalizing the practice of "passively hastening death" by physicians. In so doing, they have had to confront state statutes criminalizing not only assisted suicide but homicide. They have done so by concluding that passively hastening death does not meet the requirements of these offenses and thus is not criminal conduct.This article reexamines this approach to the legalization of passively hastening death and concludes that most of the arguments accepted by courts for its noncriminality are spurious. A more honest approach is to admit that passively hastening death meets the definition of a crime but to hold that liability should not be imposed because of the existence of consent. The author applies this analysis to actively hastening death and concludes that because there are no significant reasons to distinguish actively hastening death from passively hastening death, the two should be treated the same by state courts, that is, actively hastening death (including physician-assisted suicide) should also be legal.


The cardiovascular system can be described as a network of constantly oscillating physical, hormonal and neural feedback loops. They operate in a concerted fashion in order to provide the body with its daily needs. Inability to maintain cardiovascular homeostasis may be the result of relatively well-tolerated but repeated disturbances, or a single overwhelming event. The development of clinical cardiovascular disease may thus be viewed as failure to compensate for such alterations successfully.

Abstract
1 The sympathetic nervous system plays an important role in the regulation of blood pressure. Plasma catecholamine concentrations are considered to be reliable indices of sympatho-neuronal (noradrenaline) and sympatho-adrenal (adrenaline) activity and reactivity in man.

2 Sympathetic and adrenal activity and reactivity in young patients with essential hypertension or hyperkinetic heart syndrome were compared with an appropriate control group matched for age. The groups of hypertensive patients and patients with hyperkinetic heart syndrome could be clearly distinguished from control subjects on the basis of circulating catecholamine levels at rest.

3 A clear-cut increase in circulating noradrenaline and adrenaline was observed in young patients with essential hypertension and hyperkinetic heart syndrome at rest. Clinically, hypertensive patients were characterized by elevated systolic and diastolic blood pressure and increased heart rate, whereas patients with hyperkinetic heart syndrome had increased heart rate and increased systolic blood pressure, whereas diastolic blood pressure was normal. At rest, there was a significant positive correlation between heart rate and circulating catecholamines in both groups of patients. In hypertensives a positive correlation between heart rate and plasma adrenaline concentrations, in patients with hyperkinetic heart syndrome a positive correlation between heart rate and plasma noradrenaline concentrations could be observed. In addition a positive correlation between plasma noradrenaline concentrations and systolic blood pressure in all groups of patients studied, was obtained.

4 Sympatho-neuronal and sympatho-adrenal reactivity during mental stress or physical exercise increased in both groups of patients, mirrored by an increase in blood pressure and heart rate.

5 Pindolol, a potent non-selective β-adrenoceptor blocking drug with intrinsic sympathomimetic activity and minimal membrane stabilizing properties, administered in a single oral dose of 10 mg, diminished the exaggerated sympathetic tone in both groups of patients by attenuating circulating catecholamine levels at rest or during mental stress, but not during physical exercise.


This experiment was conducted in research station of Fars in 2004, in a piece of Land with a clay texture. In order to evaluate the different ratios of CORN and SOYBEAN intercropping, in comparison to pure culture, a randomized complete block design with 4 replications was adapted. Treatments consist of: p1 = pure corn, p2 = pure soybean, p3 = 50% corn+50% soybean, p4 = %75 corn+%25 soybean, p5 = %75 soybean+%25 corn. This Experiment was conducted by using replacement system. Evaluated factors are as the following Soybean and corn seed yield in pure culture and intercropping, Land Equivalent Ratio, Relative corn yield, Relative soybean yield, aggressively. Results showed that the treatment with %75 SOYBEAN+%25 CORN with LER = 1.19 and also the treatment with %50 soybean+%50 corn with LER—1.11 have preference %19 and %11 respectively higher yield compared to pure culture. Also in relation to the aggressively in treatment with %50corn+%50 soybean and also with %75corn+%25soybean, corn was dominant. Finally ...


Microwave radiation offers the very important feature of inducing volumetric heating in a sample that leads to faster processing rates and lower thermal gradients in the heated material than the conventional techniques based on boundary heating. This feature has led to the use of microwaves as heating means in many practical applications, especially related to food technology. Given the importance of microwave heating, the abundance of reported studies in the literature regarding its modeling is not surprising. Microwaves create very complex heat source patterns in the heated material. These patterns can be found from the solution of the Maxwell equations. Although their two(2D) and threedimensional (3D) solutions are feasible1 (but computationally demanding), the one-dimensional (1D) case is usually invoked to attain greater insight on the physics of the problem. The usual 1D approximation refers to the normally irradiated slab2,3 (Cartesian geometry) and the radially irradiated cylindrical sample (axisymmetric case). The latter 1D model has been used to simulate the heating of cylindrical samples in actual microwave ovens based on the dubious assumption that multiple reflections from the oven's wall lead to an approximately 1D pattern in the sample.4 Recently, it has been experimentally shown that the temperature profile in a rotated cylindrical sample is axisymmetric so the radially irradiated model is appropriate for this case.5 The heat source patterns resulting from the Maxwell equations for the 1D case are not so simple, especially for the case of nonuniform dielectric properties for which a numerical solution is needed. For this reason, several simple expressions for heat sources based on Lambert's law have been proposed. Although the limits of validity of these expressions for the case of an 1D slab have been extensively studied years ago,6 only recently have the corresponding limits for the axisymmetric geometry been proposed.7 In the present work, the approximate expressions for the heat sources in a radially irradiated cylindrical sample are reviewed and the corresponding validity region for the best one (much wider than that proposed previously7) is given. In addition, criteria for the application of simplified expressions for sources in the case of temperaturedependent dielectric properties are presented for the first time.


This paper studies the bullwhip effect problem in supply chain networks with information sharing.We first propose the basic system state transition model of supply chain inventory networks and a dynamic inventory control strategy.Then we extend this model into supply chains with limited information sharing and study its system dynamics.The inventory strategy design problem is transformed into the linear matrix inequalities optimization problem.The effect of information sharing in reducing the bullwhip effect is studied.Results show that the types of information sharing and their timeliness have different effect on the bullwhip effect.Simulation study also shows the effectiveness and application of the dynamic inventory control method in reducing bullwhip effect.


High angular resolution diffusion imaging (HARDI) methods have enabled the reconstruction of complex spin diffusion profiles in central nervous system white matter through diffusion-weighted MRI. For recovery of the underlying fiber orientations, conventional spherical deconvolution techniques based on spherical harmonics typically have difficulty producing fiber orientation distributions (FODs) that simultaneously satisfy the physical constraints of being real, symmetric, and non-negative. In this work, we propose a novel approach for HARDI reconstruction that is guaranteed to generate FODs satisfying these constraints. By using a meshed representation of the unit sphere, we formulate the spherical deconvolution as a convex optimization problem and compute the solution using a projected gradient descent algorithm. Flexible regularization is also included in our method to allow for tuning the sharpness of the reconstructed FOD. In our experiments, we present simulated results to examine the effects of varying the regularization parameters, and we illustrate the robustness of our method by applying it to several biological data sets to reconstruct known white matter fiber geometry.


ABSTRACT This article, based on a deep ethnography in schools located in a disadvantaged multicultural context in Geneva (Switzerland), questions the way in which the local school system and teachers comprehend the cultural diversity of students and their parents. Oscillating between recognition and assimilation, teachers publicly adhere to discourses that emphasise cultural diversity, while limiting its expression, especially when a student encounters school difficulties. Teachers' meetings with parents are significantly influenced by the majority perspective, leaving the parents with little place to express their own needs. Nonetheless, within the conversation, some parents are able to assert practices that differ from those promoted by the host society. Ultimately, it seems that, in the absence of a multicultural position, teachers are limited to adopting hybrid practices that create unease and are evidence of limited understanding of multiculturality.


Two process were used to incorporate Eu and Tb respectively on the porous silicon (PS) samples. First, samples were anodized in HF + IPA during 3 minutes; the samples were then washed and dried. A solution of the salts in water was deposited onto the samples' surface. The samples were heated until the solvent was evaporated and then the anodizing process continued for another three minutes. In the second method the anodizing process was carried out using an electrolyte composed of a mixture of the respective salt diluted in water, HF and IPA. The presence of Eu or Tb on the PS was confirmed by photoluminescence spectra taken in the visible region. The photoluminescence spectrum of samples present a wide background, characteristic of porous silicon and some electronic transitions corresponding to the Eu3+ or Tb3+ ion. Results show that it is possible to incorporate rare earth ions in PS samples at low temperature annealing (60 °C) during anodization process. (© 2005 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)


Glioblastoma is a common and aggressive type of primary brain tumor. Several anticancer drugs affect GBM (glioblastoma multiforme) cells on cell growth and morphology. Taxol is one of the widely used antineoplastic drugs against many types of solid tumors, such as breast, ovarian, and prostate cancers. However, the effect of taxol on GBM cells remains unclear and requires further investigation.

Close apposition of the mucous surfaces\p=m-\theattachment reaction\p=m-\occurson implantation in the mouse (Potts, 1966, 1968; Nilsson, 1967; Reinius, 1967; Potts & Psychoyos, 1967b) and the rat (Mayer, Nilsson & Reinius, 1967; Nilsson, 1967; Potts & Psychoyos, 1967a). Since both these species have an eccentric implantation, it seemed possible that the occurrence of the attachment reaction might be correlated with the type of implantation. The ultrastructure of the uterine surface epithelium was therefore examined at preimplantation and implantation in animals representative for different modes of implantation \p=m-\eccentric(the hamster), central (the rabbit and the mink) and interstitial (the guinea-pig). The animals were bred under standardized conditions. Mating of the animals was verified in the hamster and guinea-pig by the presence of vaginal spermatozoa (Day 1 of pregnancy) and in the rabbit and the mink by controlled mating. The preimplantation and implantation stages were obtained from the ham¬


Potassium silicate glasses, crystal, and melts are investigated by the differential scanning calorimetry (DSC). The temperature dependences of their heat capacities, the enthalpies of melting of crystals, and the fictive temperatures of glasses are determined. The results obtained are considered within the models of thermodynamic similarity and local structural distortions with the use of the data available in the literature on the structures of glasses, melts, and crystals. Similarities and differences in the behavior of sodium silicate and potassium silicate glasses are revealed.


Indeed, when we sum up the whole matter, we shall, I think, find that the editing of an old text, however much it may call for literary appreciation and imagination, must in the first place be based upon the most careful research into surviving evidence, and that, however much it may depend for its foundations upon that kind of common sense which some would dignify by the name of 'science', it is also, and perhaps in all its finer achievements, of the nature of an art.1


Introduction Early Intervention Services for Early-Phase Psychosis have shown efficacy and effectiveness (Correl C, JAMA). In Pamplona, Spain, there is an Early Intervention Program that has been providing multiprofesional assistance for First Psychotic Patients for the last two years. Objectives The aim of this study is to analize the longitudinal effects of the different interventions in several functional variables: GAF, Occupational State, CGI-CogS, QLS, Sofas and WHODAS II applied to 240 patients during two years of follow-up. Methods We apply an standard evaluation protocol to every patient at different times: premorbid, initial time and at months 6, 12, 18 and 24. We analyse the data with the SPSS statistical program to see the results in these variables. Results The GAF scale shows a decline during the first 6 months, but tends to reach and maintain the premorbid levels after a year of treatment. Regarding baseline, patients with normalized jobs or studies are 60.7%. This percentage persists during the next months of follow-up but decline at the 24th month Both the Whodas and Sofas scale show improvement tends. The QLS results show a progresional improvement in every subcale during the whole time of follow-up. Conclusions The Early Intervention Services in Psychosis improve, not only psychopatological dimension but also functional areas, what is important for the whole recovery of First Psychotic Patients.


Axial magnetic field (AMF) can effectively control vacuum arc by making it maintain diffuse state. In this paper, a quadrupolar contact which can generate a AMF is investigated by simulations and experiments. Experiments were carried out at circuit current from 12 to 28kA, and at least three experiments were performed for each current level. By using a high-speed digital video camera, the arc behavior was recorded, meanwhile, the arc voltage and arc current were also recorded. The magnetic field distribution and Ampere Force were calculated and analyzed. As a result, the evolution process of the arc can be interpreted. Simulation results show that a quadrupolar axial magnetic field distribution was generated by the special current flow. It was observed that arc column was distributed in four areas in the electrodes at low current and small gap distance. With the current and gap distance increased, anode became active and anode jets were generated.


Thirteen fingered citron accessions,1 citrate acid orange and 6 citron accessions were collected and fourteen genotypes were introduced and survived in the germplasm resources garden. Based on the biological traits,the genetic diversities of 20 samples were evaluated by ISSR markers. A total of102 DNA bands were amplified from the 11 polymorphic primers,which were screened from 100 ISSR primers. Among those obtained bands,58 were polymorphic ones,accounting for 56.9% polymorphism.The genetic similarity coefficient among the accessions ranged from 0.608 to 0.990. At the point of the similarity coefficient 0.798,all the accessions might be separated into three groups,fingered citron,citrate acid orange and citron,meanwhile three pieces of Yabian mutants belonged to a new group of fingered citron.


This paper deals with a method adapted to create a personal assistant based on emotion recognition. It explains how the emotions of users can be recognized and suggests the relevant methods. Now, we have an abundant number of personal assistants and chatbots: we took one of such bots a step ahead and made our assistant to automatically recognize users' emotions. Through this, our assistant is made to acquire empathy and usage with a lot of fun and advantage. The application has the potential to be used in mobile phones. Many people suffer from social anxiety and depression; our assistant is intended to help them by identifying their emotions and by suggesting ways to cheer them up. The assistant induces the user to be more connected to their phone and also to other people. Initially, our idea was to create a futuristic application, but later this turned out to be more than that. It proves to be advantageous for all mobile phone users. We created a simple personal assistant (Edith) with emotion-sensing ability. We used deep learning techniques to detect users' emotions. We illustrated our model with a lot of human faces displaying different kinds of emotions. Achieving a decent accuracy while recognizing the emotion was the hardest part in this attempt because very slight differences in facial muscles portray dissimilar emotions; identifying the pattern in similar feelings is challenging. We overcame these difficulties by choosing an appropriate dataset with many images to depict our model to recognize the emotions correctly. Our model achieved better accuracy by doing so.


Single crystals of metal (Cu2+ and Mg2+) doped L-histidine bromide (LHB) salts were synthesized and single crystals of synthesized salts were grown from aqueous solutions by isothermal slow evaporation technique. Structural studies on the grown crystals were carried out by single crystal XRD analysis and found that the grown crystals crystallize in orthorhombic structure. Fourier transform infrared (FTIR) spectroscopy and thermal analysis (TG/DTA) were performed to study the molecular vibrations and thermal behaviour of the crystals, respectively. The NLO activity of the grown crystal has been checked by second harmonic generation (SHG) test. Energy dispersive X-ray spectroscopy (EDX) study reveals the presence of metal in the doped LHB crystals.


A ring R has the (A)-property (resp., strong (A)-property) if every finitely generated ideal of R consisting entirely of zero divisors (resp., every finitely generated ideal of R generated by a finite number of zero-divisors elements of R) has a nonzero annihilator. The class of commutative rings with property (A) is quite large; for example, Noetherian rings, rings whose prime ideals are maximal, the polynomial ring R[x] and rings whose total ring of quotients are von Neumann regular. Let f : A → B be a ring homomorphism and J be an ideal of B. In this paper, we investigate when the (A)-property and strong (A)-property are satisfied by the amalgamation of rings denoted by A ⋈fJ, introduced by D'Anna, Finocchiaro and Fontana in [3]. Our aim is to construct new original classes of (A)-rings that are not strong (A)-rings, (A)-rings that are not Noetherian and (A)-rings whose total ring of quotients are not Von Neumann regular rings.

introduction For public-sector administrators burdened with the task of recruiting and retaining information technology (IT) professionals, these are difficult times. A shortage of IT personnel combined with intense demand for new technology skills has made recruiting and retaining staff harried pursuits; additionally, the demand for technical workers in corporate America keeps rising (Paw-lowski, Datta, & Houston, 2005). This demand for workers with leading-edge IT skills is exacerbated by the looming retirement of seasoned government workers, estimated at a 30% reduction in public-sector workforce across state governments by 2006 (Council of State Government [CSG], 2002). Despite the mounting demands on IT to be leveraged in state governments as a cost-reducing and efficiency-increasing tool (Levinson, 2003), even with economic recovery (Information Technology Association of America [ITAA], 2004) many scholars and industry analysts fear a widening shortage in available IT professionals (Pawlowski et al.). Pawlowski et al. suggest that for state governments, more so than private-sector firms, the problem has become acute, heightened by not only recruitment and retention barriers (CSG, 2000), but also by an ideological backlash against contracting for IT services with offshore firms (Hira, 2004). In recent research, barriers to recruitment (low base salaries, lack of qualified candidates, a poor image of civil service, and limited advancement opportunities) and retention (inability to compete with the private sector, low base salaries, insufficient reward systems, and lack of advancement opportunities) were documented through a survey of 400 IT professionals working in state agencies and universities (Pawlowski et al.). The ubiquitous nature of information technology at all levels of government and the core requirement to recruit and retain qualified technology professionals calls for an expansion in the body of research; this research can provide invaluable insight into the success and failure in public-sector information technology human resource practices. The intent of this research is the utilization of the DeMers' (2002) seven-pronged approach to critically examine Mississippi state government agencies with the expected result of assessing the effectiveness and efficiency of the IT personnel classification system. This leading-edge and highly effective IT personnel classification system, designed specifically to improve IT recruitment and retention, was implemented by the State of Mississippi in partnership with the Hay Group, an internationally known human resource consultancy.


To determine if it is possible to exclude staging bone scans in a greater proportion of patients if more consideration is given to T stage and Gleason score, as recent guidelines from the National Institute of Clinical Excellence state that routine staging bone scans for prostate cancer are unnecessary in patients with a prostate specific antigen level (PSA) of < 10 ng/mL and Gleason scores of < 8.


Twelve okra genotypes were crossed in diallel fashion excluding reciprocals to generate 66 one-way hybrids. All the F1's along with their parents were grown at Vegetable Research Farm of the Department of Vegetable Crops, Punjab Agricultural University, Ludhiana, Punjab during the rainy season of 2004–05. High genotypic and phenotypic coefficients of variation were noticed for number of primary branches per plant indicating maximum variability among the different genotypes. High estimates of heritability coupled with high genetic advance obtained for number of branches per plant, total yield per plant and marketable yield per plant indicating presence of additive gene effects which indicated the effectiveness of selection for these traits. Presence of high heritability coupled with low genetic advance for days to fruit picking, average fruit weight, plant height, internodal length, number of fruits per plant, fruit diameter and average fruit length revealed that straight selection has limited scope for further improving these traits.


Roughening procedures including the early stage of the O 2 + -induced ripple formation of GaAs were studied quantitatively by scanning tunnelling microscopy (STM). Detailed examinations of the beginning of topography development using fast Fourier transform of the STM images revealed that the ripple formation was not caused by any accidental defects, particles or original irregularity on the substrate, but solely by the conditions of the ion beam. A systematic investigation of the rippled GaAs surface produced under various O 2 + bombardment conditions was conducted. The ripple wavelength and the transition depth were almost exactly proportional to E P cos θ, where E P and θ are the energy of the ion beam and the incident angle, respectively. For GaAs, the secondary ion yield transition occurs when the slope of ripples facing the incident O 2 + beam reaches a saturation angle of 20-30° from the macroscopic surface plane. Topography change on other III-V semiconductors was also examined for comparison. There was no ripple generation observed for GaP; InP gave a ripple-like structure without secondary ion yield change. A relatively rough surface resulted on GaSb and InAs at a much shallower depth than for GaAs. Rippling and ion yield changes during depth profiling have been suppressed successfully by sample rotation even in a magnetic sector-based instrument.

ABSTRACT Since bacterial quorum sensing system has been verified to regulate many microbial physiological activities, such as virulence factor production and biofilm formation in pathogens, blocking quorum sensing has being recognized as a viable approach for the development of novel therapeutics in treating bacterial infections. In this study, quorum quenching activities of marine actinomycetes isolated from seawater sample were investigated. Out of 56 morphological different strains, 5 strains had been found exhibiting anti-quorum sensing activity against the violacein production of Chromobacterium violaceum 12472. One highly active strain HY026 was identified as Streptomyces parvulus based on the 16S rDNA sequence analysis and morphological features. Spent culture medium of HY026 could also significantly inhibit the biofilm formation of four bacteria. One major active compound named F1-4, accounting for 26.3% of crude extracts, was obtained from HY026 cultures and identified as actinomycin D based on the analysis of the NMR and MS. F1-4 could significantly inhibit the violacein production of C. violaceum with the inhibition rate of 64.9% but not affect the bacterial growth at the concentration of 12.5 µg/mL. F1-4 could also inhibit the prodigiosin production of Serratia proteamaculans 657 with the pigment inhibition zone of 13.5 mm at concentration of 25 µg/disc without affecting the bacterial growth. Another pure compound, cyclic (4-hydroxy-Pro-Phe) was also isolated and identified from this actinomycetes strain. The higher production and easier isolation of actinomycin D from S. parvulus HY026 indicated that this strain could be a potential source of quorum sensing inhibitors.


The first component of the Tower Neighborhood Renewal program has been to inventory the resource, to increase the value of the buildings through infrastructure updates, and to determine a long-term management strategy. In 1968 Buckminster Fuller visited the city and wrote that "in Toronto, an unusually large number of high-rise apartments poke above the flat landscape many miles from downtown...this type of high-density suburban development is far more progressive and able to deal with the future than the endless sprawl of the U.S."2 Today that high-density development provides Toronto with a distinct urban form. Compared with Chicago, for example, the metropolitan area of Toronto is almost twice as dense,3 and the number of postwar apartment towers in Toronto is greater than the number of all building types 12 stories and over (including office towers) for any North American metropolitan region other than New York.4 The development of the tower-in-thepark building typology occurred in Toronto for a number of reasons. Initially it was supported as a development policy by the municipal government, influenced by many of the European émigré planners who had arrived in the city, including important figures such as Hans Blumenfeld and Gordon Stevenson.5 Secondly, the Canadian Mortgage and Housing Corporation provided financial support for this building type as a response to the dramatic need for housing after the war and as recognition of the need for progressive housing policies. And thirdly, this boom was also tied to technical innovations in the Canadian construction industry, such as the "flying form," which increased the speed and efficiency of high-rise construction.6


Introduction: Obstructive sleep apnea (OSA) is a neglected chronic disease probably emerging under appropriate epidemiological conditions in Chile. Material and method: From the 2nd Chilean Health Survey 2010 (NHS), we estimate the prevalence of risk of OSA in population ≥18 years, as a derived proxy from STOP-Bang Questionnaire. A clinical prediction rule (CPR) (habitual snoring, daytime sleepiness, nocturnal breathing pauses, blood hypertension, BMI >35 kg/m2, age >50, neck circumference ≥43 cm (men) and ≥41 cm (women) and male) was constructed. From a global score subjects were classified as: Low ( Results: 5,069 records were obtained, mean age 48 ±18 years, 60% women. A subsample of 4,234 fulfil the criteria per the CPR. The expanded sample (representing 11,279,865 persons), allows the following results: Low risk 60.7% (CI 95%, 58-63.4), Medium 31.1% (28.7-33.6) and High 8.2% (7-9.5). ). Men with Low risk 45.8% (41.7-49.9), Medium 41.1% (37.3-45.1), High 13.1% (11-15.5). Women with Low risk 74.6% (71.6-77.4), Medium 21.8% (19.4-24.4), High 3.6% (2.5-5.1). We observed an increasing trend in High risk of OSA from 0.3% (0-1.8) in 18-24 years old group to a 22.9%( 18.4-28.2) in people aged >65 years old. Men with the highest prevalence of high risk OSA are in 7 of the 15 Regions: Araucania (24%), Aysen (21.3%), Coquimbo (18%), Maule (17.8%), Bio-Bio (17%), Arica (16,2%) and O9Higgins (15.7%). Conclusion: OSA is a prevalent condition in Chilean Population, is higher in men than in women and a positive age trend of high risk OSA was observed.


Erorpe is the craddle of insurance and now it is the most mature area over the world. The development of Eroupean insurance is supported by the fine macroscopic surroundings. Under the abroad elicitation, China's insurance should be guarenteed and supported by the same kind of environment created by laws and regularities.


SIMD accelerators and many-core coprocessors with coarse-grained and fine-grained level parallelism, become more and more popular. Streaming SIMD Extensions (SSE), Graphics Processing Unit (GPU), and Intel Xeon Phi (MIC) can provide orders of magnitude better performance and efficiency for parallel workloads as compared to single core CPUs. However, parallelizing irregular applications involving dynamic data structures and irregular memory access on these parallel platforms is not straightforward due to their intensive control-flow dependency and lack of memory locality. Our efforts focus on three classes of irregular applications: Irregular Trees and Graphs Traversals, Irregular Reductions and Dynamic Allocated Arrays and Lists, and explore the mechanism of parallelizing them on various parallel architectures from both fine-grained and coarse-grained perspectives. We first focus on the traversal of irregular trees and graphs, more specifically, a class of applications involving the traversal of many pointer-intensive data structures, e.g. Random Forest, and Regular Expressions, on various fine-grained SIMD architectures, e.g. the Streaming SIMD Extension (SSE), and Graphic Processing Unit (GPU). We address this problem by developing an intermediate language for specifying such traversals, followed by a run-time scheduler that maps traversals to SIMD units.

ABSTRACT. Two odour receptor cells were physiologically identified within male antennal hair sensillae of the gypsy moth, Lymantria dispar L, and the nun moth, L. monacha L. In the gypsy moth, one cell responded to (+)‐disparlure, while a neighbouring cell responded to (‐)‐disparlure. In the nun moth both cells responded to (+)‐disparlure. The lack of sensitivity to (‐)‐disparlure in the nun moth was corroborated by electroantennogram (EAG) recordings, which indicated no affinity to this enantiomer. Single cell responses of male gypsy moth to different concentrations of the synthetic enantiomers of disparlure were then compared to responses elicited by hexane extracts of female glands of both species. The gypsy moth's extracts stimulated almost exclusively the receptor cell specialized for (+)‐disparlure, while both cells were simultaneously stimulated by the extracts of the nun moths. From the response characteristic of the cells it is estimated that pheromone production of the nun moth is about 10% (+) and 90% (‐)‐disparlure, and that of the gypsy moth is almost 100% (+)‐disparlure. Stimulation of the antenna of each species by female gland extracts of both species did not indicate the presence of receptors for other hexane elutable pheromone components in either species.


NCA (LiNi0.85Co0.10Al0.05-x MxO2, M=Mn or Ti, < 0.01) cathode materials are prepared by a hydrothermal reaction at 170°C and doped with Mn and Ti to improve their electrochemical properties. The crystalline phases and morphologies of various NCA cathode materials are characterized by XRD, FE-SEM, and particle size distribution analysis. The CV, EIS, and galvanostatic charge/discharge test are employed to determine the electrochemical properties of the cathode materials. Mn and Ti doping resulted in cell volume expansion. This larger volume also improved the electrochemical properties of the cathode materials because Mn4+ and Ti4+ were introduced into the octahedral lattice space occupied by the Li-ions to expand the Li layer spacing and, thereby, improved the lithium diffusion kinetics. As a result, the NCA-Ti electrode exhibited superior performance with a high discharge capacity of 179.6 mAh g−1 after the first cycle, almost 23 mAh g−1 higher than that obtained with the undoped NCA electrode, and 166.7 mAh g−1 after 30 cycles. A good coulombic efficiency of 88.6% for the NCA-Ti electrode is observed based on calculations in the first charge and discharge capacities. In addition, the NCA-Ti cathode material exhibited the best cycling stability of 93% up to 30 cycles.


The achievements in Chinese philology are outstanding, but linguistics (the science of language) is still in its youth. Chinese have known about the science of linguistics for just over fifty years. In the world as a whole, linguistics is a junior member among the sciences. As for Chinese linguistics, it is seventy or eighty years behind European linguistics.


As a part of the Intimacy Unguarded project, Morra and Talbot invited US writer and editor of the Native Agents series for Semiotext(e), Chris Kraus (Aliens and Anorexia, Summer of Hate, I Love Dick, Where Art Belongs) to visit Central Saint Martins. This event took place before the TV adaptation of I Love Dick, when the book had a cult status, but not yet the global reach of the televisual. The book uses a series of letters, feverishly penned by 'Chris' to 'Dick', the man with whom she is obsessed, as a structure for revealing the way the intimate is bound to critical thinking. Kraus' work interweaves life experiences with references to artists and artwork, critical theory and philosophy. It was a pleasure to personally introduce our students (an important part of the Intimacy Unguarded project is our inclusion of CSM Art Program students from BA to PhD in the development of our project and events) and participants from Raven Row and Afterall to Kraus through an open seminar in which we invited participants to 'Write A Letter to Chris Kraus', and to hear Kraus's lively and insightful responses. We have included three of the letters (with grateful thanks to their writers; Helena De Pulford, Georgia Mota and Natasha Soobramanien) in this issue, as well as a couple of excerpts from I Love Dick, by way of giving a flavor of Kraus' métier and marking the public Intimacy Unguarded event where Kraus gave a reading and engaged in a lively and thought-provoking Q&A with Emma Talbot.


University of Hawai'i Doctorate in Professional Educational Practice (EdD) In the fall of 2011, the University of Hawai'i College of Education initiated its Doctorate in Professional Educational Practice (EdD) program with the first cohort of thirty students. These students, representing diverse backgrounds, experiences, and perspectives, began a threeyear voyage of coursework and collaborative inquiry in applying research in practice. The program design included rigorous coursework and two major projects focused on the resolution of specific problems of practice. The first, a consultancy project, aimed at working with clients in the local community to utilize the application of research in solving problems arising from the educational practice of clients. The program culminated with each student conducting an independent research study of their choice and publishing their findings in a dissertation. The EdD program distinguishes itself from the PhD program in that it provides an opportunity for students to explore a problem of practice and allows practical applications of the findings in the dissertation. The two authors of this chapter are graduates of the first cohort of the EdD program (2011–2014) and share their perspectives on the dissertation experience.


Amid a growing appreciation of the harms associated with cancer screening, there has been recent emphasis on education and opportunistic screening for acral lentiginous melanoma (ALM) in dark-skinned individuals.1 Furthermore, articles have highlighted disparities in melanoma education and detection in dark-skinned individuals.2,3 While early detection has the greatest potential for reducing melanoma mortality in the short term, it is important to carefully consider incidence, survival, and mortality in populations targeted for screening. In dark-skinned patients, could increased pressure to detect ALM lead to significant harms in return for minimal benefit? It is well established that for dark-skinned individuals, ALM makes up the highest proportion of all melanoma subtypes.4 However, in a large epidemiologic study of ALM, Bradford et al4 found that the incidence of ALM was similar in non-Hispanic whites and blacks (1.8 per 1 000 000 person-years). What accounts for the differences in overall melanoma incidence and melanomaspecific survival between these groups is the low incidence of UV radiation–induced melanomas in darkskinned individuals, not any difference in ALM susceptibility or prognosis. Survival from ALM is very similar across racial groups. While 5-year ALM survival rates are slightly higher in non-Hispanic whites than in blacks (82.6% vs 77.2%), 10-year survival rates in non-Hispanic whites are slightly lower than in blacks (69.4% vs 71.5%). When ALM was controlled for tumor thickness or stage, no statistically significant differences were found among all racial groupsinboth5-and10-yearsurvivalrates,suggestingthat ALM is being detected at similar stages of evolution in both groups. The recent emphasis on increased efforts for early detection of ALM is highly analogous to attempts to increase pediatric melanoma awareness. Here, too, there is a strong desire to prevent any deaths from melanoma, but the absolute numbers of deaths are low and the potential harms of overdiagnosis are significant. A search within the United States Surveillance, Epidemiology, and End Results registries revealed melanoma mortality counts of less than 10 for all age groups younger than 15 years, for each year from 1973 to 2011. For individuals aged 15 to 19 years, mortality counts were 11 or less for each year from 1991 to 2011. Despite low mortality and the absence of formal screening recommendations, an epidemic of biopsies in children has occurred, likely fueled by increased public education and awareness of melanoma (eg, ABCDE [asymmetry, border irregularity, color variegation, diameter >6 mm, and evolving] criteria) and the dynamic nature of nevi in childhood and adolescence. In fact, more than 2 million nevi are estimated to have been biopsied between 2009 and 2013 in the United States in individuals 19 years and younger in order to detect 1940 melanomas, resulting in a number needed to biopsy of 1035.5 The effect of these biopsies on mortality, if any, is unknown. The ratio of benign to malignant biopsy results for melanoma is determined by diagnostic accuracy and the underlying disease prevalence of a population targeted for screening. Sensitivity and specificity of the evaluation of suspicious pigmented lesions with dermoscopy are on the order of 0.87 and 0.91, respectively. While diagnostic accuracy likely varies with experience and expertise, disease prevalence has an even bigger effect on predictive value and benign to malignant ratios. A comparison of specialized screening centers with general dermatology practices found a difference in benign to malignant ratios of 1:8.7 vs 1:29.4, respectively, which was cited to be partially a result of screening individuals with different underlying incidences of melanoma.6 A disease prevalence of 1 melanoma in every 29.4 concerning pigmented lesions would lead to a positive predictive value of 24.7% and a negative predictive value of 99.5%.6 An identical diagnostic accuracy applied to screening the palms, soles, and nails of dark-skinned individuals, assuming twice as many concerning background benign acral pigmented nevi,7 would equate to a positive predictive value of 14.1%, a negative predictive value of 99.8%, and an estimated number needed to biopsy of 59. The opportunity costs, financial costs, and morbidity associated with these invasive procedures need to be carefully considered, especially in the absence of a demonstrated effect on mortality in this setting. Unknown is the effect of longitudinal melanonychia, which is informally accepted to be significantly more common in darkly pigmented individuals, on the above estimates. In addition, although studies have shown that dermoscopy aids in the diagnosis of ALM, few studies have specifically examined the dermoscopic features of the full spectrum of benign and malignant acral pigmented lesions in dark-skinned individuals. In light of the increased prevalence of lesions in this population, the specificity of dermoscopy to distinguish ALM from benign acral pigmented lesions in dark-skinned individuals is an especially important issue. In the case of acral pigmented lesions, perhaps more concerning than the potential number of biopsies is the morbidity and harms associated with identification and surgical removal of numerous dysplasias and borderline lesions identified as a result of increased detection pressure. Acral nevi are well described in dermatopathology literature as being often misdiagnosed (most frequently false-positive but also false-negative diagnoses) owing to unique site-related atypia and common VIEWPOINT


We observe the congested traffic flow in Tomei Expressway, a Japanese expressway linking Tokyo with Nagoya. Congestion occurs at the upper stream of a traffic blockade, Nihonzaka tunnel, in contrast to preceding observations at the upper stream of an on-ramp. The flow on the fast lane is congested more severely than on the slow lane. The flow on the fast lane, however, almost always exceeds the one on the slow lane. The observed congested flow is stable and the average velocity on both lanes strongly correlated.


To access real-time information with mobile hand processor from datum,quick search approach is adopted generally. However, there exists conflict between quick search capability demand and mobile device computing capability with weaker compute processing power. From the point of hardware architecture and software arithmetic, a quick search approach to large-scale record based on multi-index was proposed. The result shows that the proposed approach applied to the corresponding hardware architecture can increase location rate greatly.


Oak leaf area index (LAI) was estimated using wide-angle photographs of the forest canopy taken from the ground at grid points throughout three sites on Cape Cod, Mass. Confidence intervals for these estimates and optimal sample sizes were calculated. Oak LAI estimates leveled off by early June when no defoliation was present. Within-plot two-dimensional spatial distribution of oak LAI was very similar to the spatial distribution of oak basal area. Consequently, there was a positive correlation between local oak leaf area and local basal area. Comparison of LAI estimates taken before and after gypsy moth, Lymantria dispar (L.), defoliation allowed the estimation of oak leaf area consumed. Leaf area loss was similar in areas of high and low host foliage densities. The correlation of leaf area lost with local density of early instars was greater than the correlation with the density of late instars.


Abstract The effect of TiO2 content on the phase compositions of sinter was conducted under reaction equilibrium at oxygen partial pressure of 5×10−3 atm. The results showed that TiO2 mainly existed in the phase of perovskite. With the increase in TiO2 content, the content of secondary hematite phase increased and the ratio of hematite and magnetite in the sinter phase decreased. Meanwhile, the ratio of perovskite and Ca2SiO4 increased and the increased level of perovskite was larger than that of the Ca2SiO4 phase. The volume fraction of the phase silico-ferrite of calcia and alumina decreased from 44·9 to 41·5%, and the chemical formula of silico-ferrite of calcia and alumina changed from 4·7CaO.9·2Fe2O3.Al2O3.2·3SiO2 to 1·6CaO.4·9Fe2O3.Al2O3.1·8SiO2 when the percentage of TiO2 was from 0 to 12 mass-% in the sinter.


The challenges of using HQEE primarily spring from its processing characteristics. There are two main difficulties associated with HQEE: HQEE has a high melting point (>98 °C / 208 °F). HQEE does not supercool but will rapidly crystallize below its melting point. This requires heating melting tanks and all process lines to ~110 °C and insulating the lines to prevent clogging. In addition, choosing HQEE precludes the possibility of hand-batching. About Us SDS Request Contact Us


Uganda is the largest sweetpotato producer in Africa and in most areas of the country, it plays and important role of providing food security in areas where it is cultivated (Bashaasha et al.1995). This role has become more prominent in areas where cassava, the second most important crop next to banana, has been destroyed by the African Mosaic virus. Bashaasha et al. (1995) identified sweetpotato post-harvest constraints such as lack of markets, poor storage facilities, limited use opportunities, among other agronomic constraints to production, as some of the major obstacles to sweetpotato development. These indicate the need to examine sweetpotato post-harvest strategies to overcome the obstacles and address the issue of food security in Uganda.


X-Sat, the first microsatellite indigenously developed in Singapore, was launched in April 2011. Following a series of checkouts, the satellite was declared operational mid Jun 2011. From then on, X-Sat was expected to go on operating for up to three years, totally unattended in the vacuum and temperature extremes of the space environment. Its isolation in space imposed a high reliability requirement for X-Sat. Redundancy to deal with single-point-failure was implemented throughout the X-Sat microsatellite system, whether it was hot, cold or k/n redundancies. If redundancy was not possible at the subsystem or unit level, then some form of redundancy was implemented at the component or parts level.


Social relationships are highly salient for problem gambling. This study investigated the effect of others' presence or cooperation with others on risky gambling behavior among healthy undergraduate students. Based on the findings that individual differences moderate the social facilitation effect and team performance, we also focused on personality traits. A total of 36 participants completed the Game of Dice Task (GDT) in three conditions, within a crossover design: the sole condition (each participant conducted the GDT individually), the parallel condition (each participant conducted the GDT in parallel with another participant), and the cooperation condition (participants conducted the GDT at the same time and were told to consult with each other). Before the experiment, all participants completed the NEO Five Factor Inventory. The results showed no significant differences among the sole, parallel, and cooperation conditions in terms of risky gambling behavior. However, safer gambling behavior in the cooperation condition was significantly and positively correlated with conscientiousness. These findings suggest that a new harm‐reduction strategy focusing on cooperation with others while gambling could be developed.


What is known about recruiting and retaining teachers for hard-to-staff-schools runs counter to many of the assumptions undergirding the teacher quality provisions of No Child Left Behind. Evidence regarding incentives, recruitment pathways, new teacher induction programs, and alternative routes shed considerable light on what needs to be done to ensure a "highly qualified" teacher for every student. Educators, armed with the right knowledge, can play an important role in getting both the funding and politics in place to create and support the policies and programs that can make a difference.
