E-commerce has had a strong impact in the Ecuadorian market due to the new trend in which many consumers seek to carry out transactions of products and services in electronic form more frequently. It is crucial that companies become present on the web so that consumers can be informed about their products or services and, at the same time, have the opportunity to shop online. This trend generates benefits for consumers such as being informed completely about the product they purchased, purchase internationally, perform comparisons between products, secure payments and saving time and resources. Similarly, the fixed costs of enterprises diminish, giving rise to greater economic benefits. This investigation discussed the possible preferences of users USFQ Diners credit card. It is explained and analyzed the motives of acquiring this credit card, types of services consumers would wish to receive, the frequency of these services, and the different ways they currently use it for. Also, it identifies the preferences of the service given by USFQ Diners credit card; if it would be used online or in a physical store, for national or international online shopping and the type of shops and items users would prefer. With this information, it generates transcendental information for companies regarding online shopping and encouraging e-commerce.


poisoning by monoxide of carbon are more common than is usually supposed, giving rise to obscure symptoms of disease. It is the exception rather than the rule to find the gas-fittings in houses perfectly tight. In almost every house one room at least will be found on close examination to possess one more or less leaky gas-fitting. The true cause of the symptoms accompanying chronic exposure to coal-gas is liable to be mistaken for an auto-toxaemia, especially as individuals constantly exposed to the presence of small quantities of coal-gas from a leak soon


We definea reductionsystem whichpreservesthestable semantics. This system includes two types of transformation rules. One type (which we call ) preserves the stable semantics regardless of the EDB (extensional database). So, it can be used at compilation time. The other (which we call ) does not preserve the stable semantics across changes to the EDB. Thus, it should be used at run time. Nonetheless can reduce the program size considerably and is quadratic time computable. Sometimes can transform a cyclic program into an acyclic one. At these times, a satisfiability solver can be used to obtain the stable models.

It is shown that the power consumption in the double-pulse bi-spectral primary source for EUV lithography can be substantially decrease by replacing pre-amplifiers in power CO2 laser with the SRS converters wavelength 1.06 μm to 10.6 μm while maintaining efficiency of EUV radiation output of illuminated plasma.


We investigate bulk superconductivity in a high-quality single crystal of Bi$_2$Pd ($\beta$-Bi$_2$Pd, space group; I4/mmm) at temperatures less than 5.4 K by exploring its electrical resistivity, magnetic susceptibility, and specific heat. The temperature dependence of the electrical resistivity shows convex-upward behaviors at temperatures greater than 40-50 K, which can be explained by a parallel-resistor model. In addition, we demonstrate that this material is a multiple-band/multiple-gap superconductor based on the temperature dependences of the specific heat and the upper critical field.


Over the last 20 years our understanding of how active faults move in earthquakes, and our ability to recognise them before they move, has increased dramatically. From a situation in the 1970s when even the most fundamental characteristics of earthquake faults, such as their depth and orientation, were known only crudely, we can now resolve precise details of their shape, position and even slip variation over their surface, without going anywhere near the epicentral region. These advances have come through the combined use of seismology and space-based surveying techniques, particularly GPS and radar interferometry, so that we are now concerned with apparent discrepancies between the results from these various techniques at a level that would have been dismissed as noise just a few years ago. At the same time we have become much better at identifying active earthquake-generating structures before they move, largely through appreciating the signature they produce in the landscape at the surface. This review outlines some of these developments and discusses where they are taking us. Perhaps we will be less embarrassed in the future than we have been in the recent past by large earthquakes that occurred on faults that were unknown or unappreciated at the time, but most of which could have been identified beforehand, given our better understanding of what to look for. We also have a much better idea of how to visualise the deformation of the continents which, after all, is where we live and where earthquakes cause most damage. The continents behave quite unlike the rigid plates in the oceans: they crumple or fragment over huge regions, so that it makes no sense to ask: "what plate is Greece, or Tibet, on?" The challenge has been to work out the overall motions in such places and see how they are achieved by slip on faults in earthquakes. Some of the processes we can see occurring today require the faulting to evolve with time and we are starting to recognise this in the landscape, identifying faults that grow, interact, or even die, becoming inactive. We are progressing beyond the goal of trying to understand how faulting achieves the present-day large-scale motions to the more profound question of how the fault configurations have evolved through time. Many of these developments have direct application in earthquake hazard assessment, in that they help us to identify active geological structures and to anticipate the likely surface deformations that accompany seismic slip on faults at depth.


Islamist extremism has been the focus of intensive global scrutiny since
 September 2001. Many states have responded to the challenge of Islamic
 terrorism with a common anti terrorist strategy. Those policies include generic
 anti violence policies that consciously avoided to mention Islam; repressive
 policies that explicitly target Muslims extremists and policies that seek to
 integrate Muslims by soft or compelling methods. The article explores these
 policies in Britain.


To simulate and accelerate of the aging effects, silicon solar cells were exposed to the different doses of co 60 gamma radiation. The current-voltage (I-V) characteristics of mono-crystalline solar cells under AM1.5 illumination condition were studied before and after the gamma irradiation. Experimental results showed that the solar cell parameters such as open circuit voltage (V oc ), short circuit current (I sc ) and efficiency (η) decrease with the increase of the gamma radiation doses. The photoelectric parameters of mono crystalline silicon solar cells degraded under gamma radiation can be significant recovered by MHz-frequency ultrasonic treatment (UST). The performance of UST to restores of the aged silicon solar cells parameters compared to thermal annealing method has been shown in this paper.


Volume shrinkage during curing reactions of epoxy thermosets has been one of the biggest concerns in the field of adhesive application, because such shrinkage creates internal stress in the cured material as well as formation of voids and cracks that allow foreign destructive substances to penetrate the cured material. To date, significant efforts have been devoted to the development and applications of socalled ''expandable monomers,'' which were designed so that they underwent the ring-opening reactions with exhibition of volume expanding behaviors. Some of them have been successfully applied to epoxy curing systems as comonomers that underwent the copolymerizations with epoxy monomers. In these cases, the volume expanding nature of the monomers effectively compensated the intrinsic shrinkage of the epoxy monomers. However, in order to achieve such copolymerizations, the structures of the expandable monomers must be tailored so that they react efficiently under the specific curing conditions. This issue sometimes limits the range of applicability of the expandable monomers. For example, curing reactions based on cationic and anionic ring-opening polymerizations of epoxides have been well-modified by the properly designed expandable monomers, but polyaddition-type curing reactions such as epoxy–amine systems are still waiting for efficient molecular designs of additives for shrinkage suppression. Herein we report a new concept for suppressing curing shrinkage of epoxy thermosetting formulations, which would provide more simple and versatile molecular designs of additives. The concept is based on utilization of thermal dissociation of pseudopolyrotaxane (PPRtx) into their components, which would accompany increase in free volume (Scheme1). Polyrotaxane has been one of the attractive motifs of supramolecular construction. It consists of a central axis and plural ring molecules. The ring molecules are interpenetrated by the axis, of which both chain ends are capped with sufficiently bulky groups to prohibit dissociation of the rings from the axis. The resulting topologically interlocked structure leads to various unique properties of materials having polyrotaxane structure, which are not attained by molecular systems constructed by covalent bonds. PPRtx is a kind of supramolecules, which consists of an axis and rings, similar to polyrotaxane. The distinctive structural characteristic of PPRtx is that its axis is not end-capped to allow us to control its formation and dissociation into the components by thermal modulation. Transformation of polyrotaxane to the corresponding dissociable PPRtx by selective removal of end-capping groups has been studied as a potential programmed drug delivery system. Dissociation behaviors of PPRtx upon switching external environment such as pH have been studied. In the present work, the employed PPRtx was composed of b-cyclodextrin (b-CD) as the tubular component and Correspondence to: T. Endo (E-mail: tendo@me-henkel. fuk.kindai.ac.jp)


The diversified essential properties of the stage-n graphite alkali-intercalation compounds are thoroughly explored by the first-principles calculations. According to their main features, the lithium and non-lithium materials might be quite different from each other in stacking configurations, the intercalated alkali-atom concentrations, the free conduction electron densities, and the atom-dominated & (carbon, alkali)-co-dominated energy bands. The close relations between the alkali-doped metallic behaviors and the geometric symmetries will be clarified through the interlayer atomic interactions, in which the significant alkali-carbon chemical bondings are fully examined from the atom- and orbital-decomposed van Hove singularities. The blue shift of the Fermi level, the n-type doping, is clearly identified from the low-energy features of the density of states. This study is able to provide the partial information about anode of Li+-based battery. There are certain important differences between AC$_6$/AC$_8$ and Li$_8$Si$_4$O$_{12}$.


The article provides an overview of some structural and conjunctural challenges for the funding of State education, particularly secondary education (the 3 years of schooling offered after the 8-year period of compulsory education), showing that the trend of governments has been to spend less per pupil, despite the official discourses exhalting the quality of education. The structural challenges examined include direct and indirect privatism of government policies, the non-compliance of a constitucional requirement that a certain percentage of taxes be invested in education, the loss of funds linked to education caused by inflation and fiscal policies, and the little reliability of Audit Offices. Among the conjunctural challenges we have examined the Fundef (a fund set up by the federal government to finance compulsory education), which leaves out the secondary education; the reduced federal contribution to the secondary education; and the fragility of the proposal contained in the 10-year National Education Plan and the 'judicious' use of public money. Finally, we examine the perspectives of education funding in Lula's government, which are not apparently bright in view of the emphasis of his government on the 'fiscal adjustment', the result of which was a reduction in real terms of the funds for education in 2003. We have also analysed the virtues and limits of the Fundeb (the Basic Education Fund).

Abstract The demands and effects of warfare have not been one of the traditional concerns of historians of early modern English towns. This essay looks at the way in which the townsmen of York, Hull and Beverley responded to the demands of war. It explores the level of urban involvement in the king's wars, mainly but not exclusively against the Scots, and the way in which the pressure of war acted to transform relations within towns and relations between towns and their neighbours. In a period when towns were experiencing rapid economic, social and religious change, war provided one means of renegotiating power relations and allowed urban elites to expand their authority, through partnership with the Crown, vis-à-vis their fellow citizens and non-urban elites. The balance between profiting from war and being ruined by its demands was a fine one, however, exemplified by the experience of Hull in the 1540s.


Traditionally, analysis of Dynamic Contrast-Enhanced Magnetic Resonance Images (DCE MRI) requires pharmacokinetic modelling to derive quantitative physiological parameters of the tissue. Modelling, however, is a complex task and many competing models of contrast agent kinetics and tissue structure were proposed. Alternatively, raw DCE data could be analysed to find correlation with pathology in the tissue or other desired effects, for example by clustering. In this paper, we propose a new method for DCE MRI timeseries clustering. We model the data space as a Conditional Random Field (CRF) and optimize the objective function in order to find cluster labels for all timeseries. The method is unsupervised and fully automatic. We also propose a strategy to speed up the clustering process using Support Vector Machines. We demonstrate the utility of our method on two distinct problems: prostate cancer localization and healthy kidney compartment segmentation.

The field experiment on angelica ( Archangelica officinalis Hoffm.) was carried out in the years 2001-2002 at the plantations situated in Malopolska (Mydlniki near Krakow and Krolowka near Bochnia). The results of two years' investigations pointed out, that angelica plants during vegetation were infested by many pathogens. The most often noticed on the plants were angelica rust ( Puccinia anglicae ), powdery mildew ( Erysiphe umbelliferarum ) and Cercospora leaf spot ( Cercospora sp.). Moreover, many various types of disease symptoms, which were described and made a diagnosis. There were mainly spots on leaves and steams, from which there were isolated most often fungi from Alternaria genus. The investigations on the salubrity of the seed material (angelica fruits) coming from different sources showed that fungi from genus Alternaria were likely to transfer by seeds and caused disease symptoms on plants during vegetation. Fungi from genus Alternaria were most often isolated from angelica fruits. Saprotrophic fungi ( Epicoccum purpurascens , Penicillium spp., Mucor hiemalis ) were also often isolated from angelica fruits. Disinfection on fruits reduced number of isolated fungi and bacteria.


Potassium (K+) channels, with their diversity, often tissue-defined distribution, and critical role in controlling cellular excitability, have long held promise of being important drug targets for the treatment of dysrhythmias in the heart and abnormal neuronal activity within the brain. With the exception of drugs that target one particular class, ATP-sensitive K+ (KATP) channels, very few selective K+ channel activators or inhibitors are currently licensed for clinical use in cardiovascular and neurological disease. Here we review what a range of human genetic disorders have told us about the role of specific K+ channel subunits, explore the potential of activators and inhibitors of specific channel populations as a therapeutic strategy, and discuss possible reasons for the difficulty in designing clinically relevant K+ channel modulators.


In this work, the dynamic behaviors of a complex pneumatic reducer valve have been studied through the pseudobond graph modeling technique. This modeling approach graphically describes the energy and mass flows among pneumatic valve components during real operational conditions. State equations have been derived from the pseudobond graph model and have been numerically solved by MATLAB-SIMULINK. To validate the accuracy of the model, simulation results are compared with the real data of an experimental setup and good agreements between them are reported. The main advantage of the proposed model over other conventional approaches such as fluid dynamics theories is that it provides a physical model which accurately predicts the system's dynamic responses without any need to run huge computer programs or establish expensive experimental setups.

Ascites represents the abdominal free-fluid accumulation. Without a clearly defined underlying cause, detailed biochemistry, microbiology and cytology analysis of ascites must be performed. The aim of our study was to determine the cause of rapidly developed ascites and the significance of used diagnostic procedures. The study involved 110 patients with rapidly developed ascites with unclear origin. The patients were observed at the dept of Gastroenterology of Zemun Clinical hospital during the period of 2000-2002. data from the medical records as well as on-examination findings, epidemiology data, routine laboratory parameters, serum-ascites albumin gradient, overall ascites protein count, and findings of ascites cytology and microbiology analysis were obtained and statistically analyzed by methods of descriptive and analytical statistics. Out of 110 patients, 72 were males, with the mean age 59.2±10.2 years and the mean complaints' presentation 1.5±1.1 months. The most frequent cause of benign ascites was liver cirrhosis (78%), while gastrointestinal malignancies predominated as malignant cause (58%), either as colonic (25%) or stomach cancer (21%). Diagnostic accuracy of serum-ascites albumin gradient and overall ascites protein count was 93% and 83% respectively. Our study pointed that benign ascites were the most frequently registered among our patients. To find out the cause of ascites, the most valuable findings were serum-ascites albumin gradient and overall ascites protein count. It's noteworthy that appropriate diagnostic schedule (clinical examination, laboratory analysis of ascites and some additional procedures) must be carried out in the patients with ascites, especially in the cases of rapidly developed ascites of unknown underlying cause.

survival (p<0.0001, Figure 1). However, its impact was minimal –the variation explained by its effect in predicting survival was 9.6% (R2=0.096). Conclusion: Long-term mortality may be attributable to many causes, not necessarily related to patients' cardiovascular or general health at the time of operation. Thus, discussions with surgeons, and long-term shared decisionmaking with primary care physicians/cardiologists should not focus solely on patients' pre-operative risk profiles, but also emphasize the importance of preventing/controlling other diseases through a healthy lifestyle and compliance with disease management protocols.


This article focuses on the efficiency of commercial banks in North Macedonia in the period from 2007 to 2020. The main goal is to assess the relative efficiency of the banking sector as a whole, and more importantly, to evaluate and analyse the impact of mergers and acquisition (M&A) transactions on banks' efficiency. For this reason, the leading nonparametric methodology Data Envelopment Analysis (DEA) has been employed, i.e., the window DEA model with two input and two output variables on a sample of 13 commercial banks. Based on balanced panel data from the banking sector of North Macedonia, the obtained results show a constant fall of efficiency of the whole banking sector, from 83.33% in 2007 to 70.06% in 2011 and 66.36% in 2020. The results of the M&A transactions case study analysis show that, in general, M&A transactions decrease banks' efficiency, i.e., they do not result in an efficiency increase. The contribution of the study is that it comprises the first study analysing the effects of banks' M&A on bank efficiency in the region of South-Eastern Europe with the application of DEA and thus, it provides valuable information for investors, bank management, M&A analysts, academic members and regulatory bodies.

We describe the metaprogramming framework currently used in Lean, an interactive theorem prover based on dependent type theory. This framework extends Lean's object language with an API to some of Lean's internal structures and procedures, and provides ways of reflecting object-level expressions into the metalanguage. We provide evidence to show that our implementation is performant, and that it provides a convenient and flexible way of writing not only small-scale interactive tactics, but also more substantial kinds of automation.


The following report describes an instrument which has many practical applications not only in physiology, but in physical science. Briefly stated the instrument magnifies the minute motions of a diaphragm similar to that of a telephone about 50,000 times and records these movements on a moving photographic film. It is well known that these movements are not perceptible to the unassisted eye, and they are so small that for a time it was supposed that there was no real motion of the diaphragm as a whole, but that the effect was molecular. A microscope which magnifies 2,000 times is considered a high-power microscope, but the magnification obtained in this instrument is twenty-five times this figure. The word "micrograph," therefore, seems appropriate for this instrument, denoting something which records microscopic movements. The phenomena of the interference of light waves is made use of for the purpose of obtaining not only the

One of the apparatus includes a first Faraday rotator having an applied magnetic field in a first direction; a second Faraday rotator optically coupled to the first Faraday rotator, the second Faraday rotator having an applied magnetic field in a second direction in opposition to the first direction; and a mirror optically coupled to the second Faraday rotator.


Concrete mixed with coarse aggregate with light substance content over standard have negative effect on the strength,durability and deformability of the concrete and lead to cracks easily. The seepage channel will be formed under the influence of the high-pressure water head. The concrete could be fracture easily on the position of the light substance when it suffered tension,which will destroy the durability and safety of the dam. Based on the national regulations,the light substance content is allowed not more than one percent in the fine aggregate and is forbidden in the coarse aggregate. The paper describes the separation principle and process of light substance in the coarse aggregate in detail,and makes the economic comparison for the kinds of process.

We present our ongoing work on the design of macroprogramming abstractions to program sensing and actuating applications using robot swarms. Robots can sample the environment and act on it where no other sensor can reach, e.g., to monitor the environment at altitude with aerial robots. Programming the individual behavior of multiple coordinating robots is difficult. We design LiftOff, a macroprogramming abstraction that allows to program robot swarms collectively, by creating the illusion of a single computing device that occupies the entire physical space of interest. We achieve this by giving variables and values in a programming language a spatial semantics. In LiftOff, values may be associated to a location, and programmers use the same variable to access different values at different locations, sparing the need to manually create a mapping from variables to spatial values. LiftOff applications execute synchronously or based on lazy evaluation. The former allows precise program analysis, e.g., using model checking, whilst the latter potentially executes faster. In this paper, we report on LiftOff's initial design and prototypes.


Ischemic preconditioning has protective effect on ischemic heart. Protein kinase Ce(PKCe) plays a key role in the intracellular signal transduction pathway of such protective mechanism. But the direct downstream substrate of PKCe related to ischemia preconditioning stays to be identified. In this study, the phosphorylated proteins by PKCe in rabbit cardiomyocyte lysate were examined. At least 4 of phosphorylated proteins with appear molecule weights of 57?kd, 35?kd, 23?kd, and 20?kd are related to PKCes kinase activity through inhibition assays of PKCe special substrate and PKC special inhibitor Ro 31-8220. The protein kinase inhibitors(PD98059 and SB20358) did not show any inhibitive effects on the phosphorylation of these proteins. Among them, the 57?kd, 23?kd, and 20?kd proteins are directly phosphorylated when the kinase activity in the lysate was eliminated by heating denaturation and the phosphorylation assay was carried out with adding of purified recombinant PKCe.They are potential direct substrates of PKCe in rabbit cardiomyocyte.


In the case of design for Large Panel Structures, the strength
 and stability of the interconnected panel are the most important
 elements. This paper was attempted to study experimentally the
strength of vertical joint of the LPS and suggested the basic data
 to develop the theoretical model of connections.
For these purposes. 19 specimens were planned according to the
connecting types and fillings of joint for 15th story apartment.
These were experimented by punchign and pure shear test. From the
 experimental study, the following conclusions were obtained. The
concrete is better than the mortar for filling material. It is
 good that the upper value of allowable strength is a half of the
 ultimate strength and 30d is sufficient for anchor length.

Background Mycobacterium tuberculosis (Mtb) survives inside a human host for a long time in the form of latent tuberculosis infection (LTBI). Latent infection of tuberculosis has the opportunity of developing into active tuberculosis (ATB), which has greatly endangered human health. The existing diagnostic methods cannot effectively distinguish LTBI from ATB. Therefore, more effective diagnostic biomarkers and methods are urgently needed. Methods Here, we screened the GEO data set, conducted joint differential analysis and target gene enrichment analysis, after filtering the disease-related database, we screened the differential miRNA related to TB. The qPCR was used to verify the miRNAs in 84 serum samples. Different combinations of biomarkers were evaluated by logistic regression to obtain a biomarker panel with good performance for diagnosing LTBI. Results A panel with two miRNAs (hsa-let-7d-5p, hsa-miR-140-5p) was established to differentiate LTBI from ATB. Receiver operating characteristic (ROC) curve showed that the area under the curve (AUC) are 0.930 (sensitivity = 100%, specificity = 88.5%) and 0.923 (sensitivity = 100%, specificity = 92.3%) with the biomarker panel for the training set and test set respectively. Conclusion The findings indicated that the logistic regression model built by let-7d-5p and miR-140-5p has the ability to distinguish LTBI from active TB patients.

: Data mining strategies have been broadly utilized for removing non-paltry data from such huge measures of data. It is helpful in numerous applications like key basic leadership, monetary conjecture, and medicinal conclusion and so forth. Data mining can be connected either as a elucidating or as a prescient device. Affiliation manage mining is one of the functionalities of data mining. This postulation proposes a couple of strategies for moving forward affiliation govern mining, affiliation administer covering up, and post mining. The way toward creating affiliation rules includes the errand of finding the set of all the successive thing sets and creating promising standards. This issue can be understood by mining Maximal Frequent Sets (MFS) alone. Despite the fact that data mining has a ton of benefits, it has a couple of bad marks moreover. Delicate data contained in the database might be brought out by the data mining devices. Distinctive methodologies are being utilized to shroud the delicate data. It is watched that a large portion of the concealing algorithms in the current writing, work at the exchanges level to conceal some touchy data. This is a tedious stride in the concealing procedure. In this theory, two new procedures have been proposed to lessen the time multifaceted nature of the concealing procedure. A major organization may have various branches spread crosswise over various areas. Handling of data from these branches turns into a colossal undertaking when multitudinous exchanges occur. Neighborhood mining may likewise create a lot of standards. Further, it is most certainly not for all intents and purposes feasible for every single nearby data sources to be of a similar size.

In an important decision for public law, the Supreme Court has ruled that ministerial guidance, given to administering authorities to oversee investment of Local Government Pension Scheme (LGPS) funds on how to discharge their powers, is unlawful. All five judges accepted that administering authorities owe "quasi-trustee" duties to LGPS members (in the area of investment) and that, as the law stands, the Secretary of State's powers are limited by these overriding duties. However, only three judges accepted that the Public Service Pensions Act 2013 did not allow central government policy to be "imposed" on LGPS funds. The two dissenting judges stated that the public interest component of the 2013 Act was significant, and, under certain circumstances, central government could legitimately seek to align LGPS fund investment with government policy. The consequence of the ruling is that the Government will not be able to interfere in the ethical investment decisions of LGPS and their members, and the principle from the Padfield case that a discretionary power granted in legislation can never be completely unfettered and must be exercised in accordance with the purpose of the legislation has been upheld.


The purpose of this investigation is to decipher the secret code of Basil that I discovered in the prologue of the Spanish edition of Aesop's Fables called Esopete ystoriado (1482), and to bring to light the importance of its resolution for the history of literature as well as for the history of science. This code states that the fables are more profitable if understood in accordance with the doctrine of Basil. After years of investigation, I came to the conclusion that Basil's doctrine can refer either to Saint Basil the Great's fourth-century treatise Oratio ad adolescentes de legendis antiquorum seu gentilium libris in which he instructs young catechumens how best to profit from an inquiry into the content and meaning of pagan literature, or to Basil Valentine's chemistry text The Triumphant Chariot of Antimony which established in Germany the precepts for the scientific method of the Age of the Enlightenment and therefore of modern Europe. In the meantime I found a strong relationship between both texts; in fact, Basil Valentine's book is based on Saint Basil's treatise, information that has been hidden for more than six centuries by a lineage of secret societies. My research focuses on how a treatise about literary interpretation written by one of the ancient fathers of the Catholic Church became the model for one of the most important scientific books in pre-modern Europe, discovering with my inquiry the important role that the Benedictine Order as well as the secret society of the Rose Cross played in that achievement. This investigation also led me to the realization that the chemist Basil Valentine was in fact the German Abbot Johann Trithemius (1462-1516), and that the Esopete ystoriado was translated from Latin to Castilian by Gonzalo Garcia de Santa Maria (1447-1521), concluding that it is impossible to separate the history of literature from the history


ABSTRACT This article examines the use of citizen participation by detectives in urgent missing person cases. Citizens can make a valuable contribution to finding a missing person, but this kind of assistance is often underutilised. We applied the Theory of Planned Behaviour to explore the extent to which attitudes, subjective norms, and perceived behavioural control influence detectives' intentions to involve citizens and the detectives' considerations underlying such intentions. To this end, a quantitative questionnaire was developed and administered to detectives from four regional police units. The best goodness-of-fit of the theoretical model was found for officers who deal with urgent missing persons cases regularly, but not often; for this group, the model explained 39 percent of the variance observed. The results show that intention is significantly related to detectives' attitudes. Subjective norms had a significant predictive value, except for officers who encounter missing persons cases frequently. Perceived behavioural control had no significant effect. The study suggests that the choice to involve citizens is mainly attitude-driven, and is determined primarily by detectives' personal affinity with citizen participation and their perception of its benefits. Perceived risks, such as damage to the investigation, have limited influence on decisions regarding citizen participation.


Natural and activated clays have been investigated as adsorbents for the removal of nickel from wastewater. Analysis of the natural clay under test showed that it was composed, approximately of 51% kaolinite, 46% montmorillonite and 3% illite, having a specific surface area of 65 m2/g. The natural clay was treated with different activators (HCl, NaCl and H2O2) to enhance its adsorption capacity towards nickel. The efficiency of such activation was greater by 16.0% and 23.2% in the case of NaCl and H2O2, respectively, relative to untreated clay. No significant increase in the adsorption capacity was brought about by HCl treatment. A limited comparison has been made between clay and activated carbon by performing isotherm studies under similar conditions. The results indicate that the adsorption capacity of clay activated with H2O2, clay activated with NaCl and natural clay is 216.9%, 204.2% and 176.1% that of activated carbon, respectively. Based solely on the adsorption capacity, an economic analysis demonstrates that natural clay is the cheapest material, followed by clay activated with NaCl and clay activated with H2O2. The relative costs of removing nickel using natural clay, clay activated with NaCl and clay activated with H2O2 were found to be 2.8%, 5.4% and 25.4%, respectively, that of activated carbon.


This paper discusses the evaluation of the structural integrity of the SAFKEG radioactive material package to ensure hazardous material confinement during the postulated accident event of forklift truck collision. When a SAFKEG Package carried by a forklift truck traveling at 7 miles per hour collides with another forklift truck moving at the same speed but in the opposite direction, the structural response of the package components represents a complex problem. Because of its complex geometric configuration and complicated contact conditions between the neighboring component interfaces, the problem can not be solved using the implicit numerical scheme that would involve solving a large number of simultaneous equations through numerical iteration. In addition, material degradation and failure caused by collision can create severe convergence difficulties in the implicit analysis. Consequently, the explicit solution method is used in the present analysis, and thus the problem has to be treated as a dynamic one even though the inertia effect is insignificant due to the low speed of the forklift trucks. Applying the explicit dynamic technique to quasi-static problems involving very large deformation and material degradation require special considerations in overcoming solution convergence and extremely long computing time. The techniques used to overcome these difficulties are discussed in this paper. This paper also discusses the development of the constitutive models of the thermal insulating and shock absorbing materials used in the SAFKEG. The resin-bounded cork material is represented by the "crushable foam" plasticity with volumetric hardening. On the other hand, the material model of the brittle foam is developed by using the combination of the Mohr-Coulomb and Drucker-Prager plasticity theories. The analysis utilizes the finite-element method and the ABAQUS/Explicit Computer Code, version 6.3. A combination of the "General Contact" method and the "Contact Pair" method is employed to simulate the complicated interface variations among the neighboring components of the model.Copyright © 2004 by ASME


JO N 2735 Stjepan Poljak was born on December 13, 1889, in Gjurgjevac, Croatia (at the time part of the AustrianHungarian Empire). He attended the classical Gymnasium (secondary school) in Zagreb and began medical studies in 1909 at Graz University, Austria (anatomy instruction by Moritz Holl), interrupted by a six-month military duty in Budapest in 1912 and by World War I [2, 9]. While at the Russian front with the Austro-Hungarian Medical Corps, he was captured in 1914 and employed in a Russian military hospital in Fastov and a field hospital in Vasilevska. He left Russia in 1917 through Arkhangelsk by ship, sailing from the White Sea around Norway to Scotland; he continued through England and France to Thessaloniki, Greece, where he joined the Serbian armed forces in 1918 [2]. Poljak obtained medical degrees from Odessa New Russia University (1916) and Zagreb University (1920). He began research on the nervous system as an assistant in neurology and psychiatry at Zagreb's Agram Neurological Clinic (1920–1928). From there he travelled extensively. He visited the Neurological Institute headed by Otto Marburg in Vienna (1921), and subsequently worked in London with Sir Grafton Elliot Smith, an early protagonist of cortical cytoarchitectonics, (1924–1925), in Madrid with Santiago Ramón y Cajal (1925),and in Chicago with the neurologist C. Judson Herrick and the neuropsychologist Karl S. Lashley (1926–1927). In 1928 he permanently moved to the United States. He became Assistant Professor of Neuroanatomy at the University of California (1929–1930), and then moved to the University of Chicago, as Assistant and later Associate Professor of Neurology (1930–1937), finally as Associate and later full Professor of Anatomy (1937–1955). The spelling of his name was changed to Poliak [3] and then Polyak [7, 10]. Poljak conducted Golgi studies of the human spinal cord [4], the central and autonomic nervous system of Chiroptera (European noctule), the cochleo-vestibular end organs, and the structure and connections of the cat visual cortex [5]. He served on the editorial board of the Journal of Comparative Neurology (1937–1948), where he had contributed 'An experimental study of the association, callosal, and projection fibers of the cerebral cortex of the cat' (1927) and 'A contribution to the cerebral representation of the retina' (1933). Poljak's recognition mainly rests on his research on auditory and visual pathways. He published 'The connections of the acoustic nerve' and 'Association fibres of the cereReceived: 30 May 2007 Received in revised form: 8 August 2007 Accepted: 2 September 2007


Vespavelutinanigrithorax, an invasive species, a direct result of increased trade and climate change, is spreading rapidly in Europe and endangering entomofauna in general and more alarmingly honeybee (Apismellifera) populations, and therefore their pollination services. All traps used now, to try to control this species, seem to be not efficient enough and non-selective. However, in the current context of massive disappearance of insects in general, it is urgent to find means of protection for the entomofauna. While no selective trapping is still occurring, we performed a pilot study to test a carnivorous plant as a potential biocontrol tool to trap V.velutina. In our study, we analyzed the hornet-capturing ability of two Sarracenia hybrids (S.juthatipsoper and S.evendine) on a 2-years period (2015 and 2016). Our results show that these plants trapped more dipterans than other taxa, and they do not attract many hornets. In such condition, both Sarracenia hybrids cannot therefore be used in a mass trapping system, because they are not selective, and too few hornets are trapped. To maximize captures of V.velutina while minimizing captures of non-target species, other systems need to be thus developed, as traps using hornet pheromone-based baiting.


GOMES, G. J. N. Development of Software for Parameter Estimation and its Application on Wind Power Plant Equivalent Model. 2020. 82p. Dissertation (Masters) São Carlos School of Engineering, University of São Paulo, São Carlos, 2020. This project focused on the development of a software for parameter estimation of non-linear dynamic models and its application on wind power plant equivalent model. To achieve this goal, a parameter estimation package was developed in Python 3 containing the estimation methods applied alongside the models used during the study. To represent wind power plants, a generic model well-known in the literature was chosen, based on its ability of representing said plants during transients. The method applied for estimation of the model parameters is composed of two optimization algorithms. At first, Mean-Variance Mapping Optimization, an heuristic approach, is used in order to reduce the search region around a feasible solution. Afterwards, a non-linear algorithm based on Trajectory Sensitivity is used to determine the local minimum, thus estimating the parameters of the model. The method validation was made using data from simulated systems. Also, a guided user interface was developed for this application, aiding new users and improving its usability. Both the package and interface projects are hosted on the author's GitHub page.


: Over the past few decades, cancer research has advanced substantially reaveling illumination on previously enigmatic aspects of cancer biology and paving the way for revolutionary therapeutic approachces. However, the resources and methods of treating cancers are still less in number which people still felt threatened by it passively. There is a nanosized extracellular vesicle (EV) called exosome have been widely used for treating cancer as well as research of it in nowadays, which contains and transports proteins, lipids, and nucleic acids. We discuss how exosome is preserved currently which uses different methods and techiniques. Next, we compared what kind of technology could be the most efficient in purifying exosome. We also point out that exosomes can either suppress or promote the cancer cells, depending on what they carrying and what kinds of enviorment they in. In this comprehensive review, we will focus on the mechanism of cargo sorting and how exosome is created and characterised from endosomes, which contains how they distribute specific cargo and how exosome carries those. Eventually, we provide a brief view of clinical courses and application of exosomes in canaer therapy in recent years and prospects for exosomes being used in further medical research.

Forty-eight of the fifty-five performance indicators were reliable in evaluation teacher performance. 2. Seven of the performance indicators were unreliable in evaluating teacher performance. 3. None of the ten performance criteria appeared to be reliable in evaluating teacher performance. 4. None of the four performance domains appeared to be reliable in evaluating teacher performance. 5. The whole instrument was reliable in evaluating teacher performance. 6. Reliability problems with the criteria and domains appeared to be an underestimate of reliability of the Kuder-Richardson Formula 20.


Abstract Poster session 2, September 22, 2022, 12:30 PM - 1:30 PM Introduction Cladosporium cladosporioides is a dematiaceous fungal agent that is known to produce a variety of clinical manifestations such as cutaneous and subcutaneous infection, corneal infection, pulmonary fungal infection, and rarely central nervous system infection. Several cases of subcutaneous mycosis have been reported from Assam, India. We are describing a similar case from Gujarat, India. Case History A 36-year-old healthy, and muscular male farmer residing in central Gujarat presented with painless nodular swelling with normal overlying skin over the posterior aspect of the left arm for the last 3-4 years. He noticed a gradual increase in the size of this swelling and numbness for the last 4 months and burning sensations for the last 10 days before presentation to the surgeon. Local part ultrasound showed a subcutaneous soft tissue lesion. Excision biopsy reported invasive fungal infection and patient was referred for further evaluation to an infectious disease facility (Fig. 1a). He had no other symptoms and comorbidities. Patient didn't recall any trauma in the past. Direct microscopic examination with calcofluor white stain from surgical site scrapping revealed mycelial structure (Fig. 1b) and yielded pure growth of a dematiaceous fungus on Sabouraud dextrose agar medium, brown to blackish colony (Fig. 1c) with olive color on the backside (Fig. 1d) after 6 days. Lactophenol cotton blue stain preparation of culture isolate showed mycelial elements with morphology suggestive of C. cladosporioides (Fig. 1e), which was confirmed at the National Culture Collection for Pathogenic Fungi, PGI Chandigarh. Review of histopathology revealed a nodule with dense acute on chronic inflammation composed of lymphocytes, plasma cells with many neutrophils with abscess containing brightly eosinophilic structures with many PAS positive septate, thin and thick walled, branching, irregularly shaped, bullous hyphae surrounded by neutrophilic boarder (Splendor Hoeppli phenomenon) (Fig. 1f). Patient was treated with capsule itraconazole 200 mg three times a day for three days followed by 200 mg twice a day along with terbinafine and total surgical excision of the subcutaneous nodule. Patient achieved a therapeutic itraconazole level (1.4 mg/l) after 1 week. Patient is currently receiving treatment. Discussion Subcutaneous mycosis is endemic in Assam. Several cases of subcutaneous chromoblastomycosis caused by C. cladosporidiosis mainly involving the lower limbs were reported from Assam. It mostly affects males engaged actively in outdoor activities during their productive age ranged from 20 to 50 years. It affects a relatively healthy, immunocompetent host and have a long history (in years) of asymptomatic nodule/swelling before diagnosis. Treatment comprises of prolonged antifungal treatment with itraconazole along with surgical excision.


Surface morphologies and fundamental characteristics of molybdenum nitride films deposited by reactive dc magnetron sputtering were studied for application to Cu diffusion barrier. A phase transformation from Mo to γ-Mo₂N was observed at the N₂ gas flow ratios (N₂/(Ar+N₂)) equal to and larger than 0.2, whereas a second phase transformation to γ-MoN phase at 0.5 N₂ flow ratio. With the variation of the N₂ ratio the surface morphologies of the films were generally smooth except the cases of 0.2 and 0.3 N₂ gas ratios, where build-up of film stresses occurred. γ-Mo₂N film was found to crystallize at the deposition temperature of 400℃. The surfaces of γ-Mo₂N films deposited up to 400℃ were smooth, but the film deposited at 500℃ had very rough surface morphology. It seems that this was due to the building-up of thermal stresses at the high deposition temperature, which might lead to hillock formation.

Objective To investigate the awareness of focus groups of endemic fluorosis and the effectiveness of health education in Tianjin. Methods A total of 2 countries were selected in Tianjin,and 3 townships were chosen in each project country.Health educational activities were carried out in the classes of grade 4- 6 in the central primary school of each selected township.In the meantime,3 villages were chosen in each selected township where the health educational activities in the community were carried out. Surveys on knowledge of endemic fluorosis were conducted before and after the health educational activities. Results The major route of the primary school students obtaining the endemic fluorosis knowledge was through school,accounting for 62.22%,while the way of housewives to gain knowledge was through TV,accounting for 58. 89%. The awareness rate of primary school students and housewives increased from57. 78%,70. 00% to 93. 33% and 91. 48%. There were no significant differences in the awareness rate among housewives with different educational background. Conclusions Health education improved the awareness rate of primary school students and housewives. We should strengthen the publicity and develop health education.


Almost four years have past since autologous blood donation program was introduced into our blood transfusion service, and an increasing number of patients scheduled for elective surgery has donated autologous blood. We experienced a total of 395 subjects as of May 31, 1991. In 1990, of the 1158 patients who underwent surgery in need of transfusion, 137(12%) were autologous blood donors; 103 of these were operated on without homologous blood transfusion. Of the 480 units collected over a year, 86 (18%) were not used. As more experience has accumulated, it becomes clear that candidates with the age of older than 64 years or younger than 16 years were allowed to participate in this program considering their general conditions. Our data also indicate that the so-called "Hb=10 g/dl, Hct=30% rule" for blood transfusion has become nothing but a standard, and autologous blood transfusion has also appeared to be beneficial from the viewpoint of cost-benefit ratio.


Review: Natural Experiments: Ecosystem-based Management and the Environment By Judith A. Layzer Reviewed by Elery Hamilton-Smith Charles Sturt University, Australia Layzer, Judith A. Natural Experiments: Ecosystem-Based Management and the Environment. Cambridge, MA: MIT Press, 2008. 365pp. ISBN 9780262622141. US$28.00, paper. Alkaline paper. This book has almost identical objectives and methodology as Doyle and Drew in their Large-Scale Ecosystem Restoration (see review in volume 28, issue 1, Review: Large-Scale Ecosystem Restoration: Five Case Studies from the United States). Both set out to assess major ecosystem restoration projects. Doyle and Drew coordinated a series of five multi-disciplinary reviews and produced an edited volume. Their book had a strong focus on holistic perspectives and each of the authors expressed themselves with admirable clarity. Layzer carried out a major review and wrote her comprehensive report of seven projects as an individual scholar. She maintained a strong commitment to rigorous methodology and presented her findings in considerable depth and detail, which makes her book less easy to read and absorb. Interestingly, both books included the Everglades and the California Bay Delta projects. In each of these, the accounts complement each other but are generally in agreement. Interestingly, there is little overlap in the underlying theory and conceptualization or in the methodological implementation of each study. Nevertheless, both challenge the common belief that such projects will achieve much greater positive effect if they involve a wide range of stakeholders. Layzer certainly achieved a valuable level of comparability across her seven studies. This lies large in her establishment of clearly defined definitions throughout, and in particular clearly defined indicators of program elements and of outcomes. She uses tables to very good effect in summarizing, for instance, apparent contradictions in the positive and negative assessments in valuation of stakeholder involvement (pp. 24-30) and in listing her criteria for evaluation of outputs and outcomes. Her study remains focused upon the relationship between the managerial arrangements for planning and implementation of environmental policies on one hand and eco-system health on the other. Many professional researchers will find her book very powerful and an excellent model of well-controlled research upon a complex and dynamic phenomenon. On the other hand, many environmental and other civic stakeholders are likely to find that she gives all too little attention to what they see as the important interactive relationship between civic society and environmental health. In her work, stakeholders are primarily seen as being involved though their membership of committees, boards and the like. They are also largely seen as Federal agencies, State agencies and the Business Communities. Given the nature and rigor of her approach, coupled with the focus on outcomes in ecosystem health as the very basis of project establishment, this is appropriate and virtually inevitable. Overall, she has produced excellent research and her book must be taken very seriously. It highlights, just as Pressman and Wildavsky did 35 years ago, the complexity and inevitable difficulty of action within a federalist structure. She does make a significant addition to our understandings of this dilemma and indicates potential directions for greater effectiveness. In view of the ways in which this book and Large-Scale Ecosystem Restoration complement each other I can only recommend that most readers will gain a more holistic understanding and benefit significantly from reading both books.

Although NASA has an adequate food system for current missions, research is required to accommodate new requirements for future NASA exploration missions. The Inadequate Food System risk reflects the need to develop requirements and technologies that will enable NASA to provide the crew with a safe, nutritious and acceptable food system while effectively balancing appropriate resources such as mass, volume, and crew time in exploratory missions. As we go deeper into space or spend more time on the International Space Station (ISS), there will be requirements for packaged food to be stored for 3 5 years. New food packaging technologies are needed that have adequate oxygen and water barrier properties to maintain the foods' quality over this extended shelf life. NASA has been unsuccessful in identify packaging materials that meet the necessary requirements when using several traditional routes including literature reviews, workshops, and internal shelf life studies on foods packaged in various packaging materials. Small Business Innovative Research grants were used for accelerating food packaging materials research with limited success. In order to accelerate the process, a theoretical challenge was submitted to InnoCentive resulting in a partial award. A similar food packaging challenge was submitted to Yet2.com and several potential commercial packaging material suppliers were identified that, at least partially, met the requirements. Comparisons and results of these challenges will be discussed.


The differences in reactivity of the different facets of a crystal to solute and/or solvent molecules is a rich source of information in the development of new materials based on small organic molecules for technological or pharmaceutical applications. Indeed, many macroscopic crystal properties such as morphology, interfacial stability, growth direction and speed, polarity, sticking propensity, wetting etc. are directly related to the susceptibility of the crystal facets to other molecular moieties during the crystallization process. In turn, controlling these properties is important for downstream unit processes associated with e.g. pharmaceutical product manufacture, such as filtration, granulation and compression.


A new method is introduced in GPRS data transmission control system design, which is to employ two microcontrollers as control core. Firstly introduced the GPRS data transmission system, and then gave a new GPRS data transmission control system hardware schematic design and software flow chart design. Compared to systems using single microcontroller, ARM or FPGA control core, the advantage of the new data transmission control system is presented. At last, after three months of testing the control system in real data transmission application, we draw a conclusion that the design is successful.


This paper discusses the semantics of possessive expressions of the kind John's book, yesterday's events, the country's president, the train's arrival, within the framework of cognitive grammar as developed in the recent work of George Lakojf and Ronald Langacker. Attention is drawn to the great variety of semantic relations that can be invoked by possessive expressions, and to the corresponding need to adequately circumscribe the range of possible relations. Even though many possessive expressions would seem, at first sight, to have little to do with 'possession' in the strict sense, it is argued that the relation of possession does have a privileged status in the semantics of the construction, that is, that the 'central' use of the possessive construction is to identify an entity in terms of its possession by another entity. Possession is analyzed as an experiential gestalt, in the sense of Lakoff and Johnson. Aspects of the experiential gestalt motivate the wider use of the possessive construction, namely as a means for uniquely identifying the referent of the construction's head noun through the elaboration, in the genitive nominal, of an entity only schematically represented in the head noun's semantic structure.


PURPOSE: An amplifier having voltage gain and reduced power consumption is provided to solve high power consumption and poor linearity of a pre-amplifier located before the amplifier. CONSTITUTION: An amplifying apparatus includes a first amplifier(AB) with which a low power is provided by a pair of low power sources(ABV1+,ABV1-), a second amplifier(C) to which a high power is supplied by a pair of high voltage sources(CV2-,CV2+), and a driving control device(DCD). The amplifying apparatus has current and voltage gain larger than 1. The driving control device includes a control device(D) switching the first amplifier off on the basis of the output signal of the amplifying apparatus, at least one current link(CL) and at least one voltage control current source(IREF). The conversion between the operations of the first and second amplifiers are controlled by a current value of the voltage control current source.


Velocities and Q values of P-and S-waves had been measured for an amphibolite and a serpentinite under different pressures and temperatures. Both rocks show a strong lattice prefered orientation (LPO) of the major minerals hornblende and antigorite. Velocities and Q values increase with pressure, with the rate being different in the three orthogonal directions (normal and parallel to foliation and lineation) and closely related to the progressive closure of microcracks. Increase of temperature under600MPa's confining pressure up to more than 600oC decreases velocihes and Q values only slightly since thermal cracking is prevented by the pressure. The anisotropy of velocities and Q values of P- and S-waves in both rocks is found to be different by nature. The anisotropy of wave velocities is the highest at low confining pressures and is caused by oriented microcracks and the LPO of major minerals. Increase of confining pressure decreases the velocity anisotropy at a smaller and smaller rate. The residual anisotropy of velocities under high confining pressures is mainly caused by preferred mineral orientation. By contrast,the anisotropy of Q is very small under low pressures and markedly enhanced as confining pressure increases. Under high pressures,the anisotropy of Qp is reversed from that of P-wave velocities:Qp is the highest whereas Vp is the lowest in the direction normal to the foliation. The generation of the pronounced anisotropy of Qp by increasing pressure is due to the directional dependent increase of contact areas on the oriented grain boundaries of the platy minerals forming the foliation plane. The increase of Q with confining pressure in the direction normal to foliation plane is a result of the decrease of damping caused by compressive strain related to that caused by shear strain. The reverse is true for X and Y directions parallel to foliation plane in sepentinite and X direction parallel to lineation in amphibolite.


Al-Irshād is an organization formed by the Arabs in present-day Indonesia in 1914, which advocates Islamic reform. This article examines its educational activities in the Dutch colonial period, elucidating the thoughts of its founder and leader, Aḥmad Sūrkatī, and the process of the integration of Arabs into the host society. Sūrkatī's thought is distinguished from other Arab reformists for its emphasis on "egalitarianism" and its lack of a tendency towards Arab nationalism. From early on, he attempted to adapt the al-Irshād schools to the colonial education system in order to attract indigenous (pribumi) students, as well. In the late 1920s, he began to be locally oriented, with a focus territorially limited to Indonesia. The educational activities of al-Irshād in the 1930s also indicated the weakning of Ḥaḍramī/Arab-orientation. By the late 1930s, the opinion of al-Irshād was decisively inclined toward integration within the host society. DOI:  10.15408/sdi.v23i3.3268


ClinlcopatboJogic correlations were reriewed in 100 cases of recent cerebral infarctions in the internal carotid artery distribution. The most frequent cause of death was transtentorial bemlation, followed in frequency by pneumonia, cardiac causes, and pulmonary embolism. Thirty-six percent of all patients and 47% of those with transtentorial bemlation died within 48 hours of cerebral infarction. Of the treatable extracerebral causes of death determined at autopsy, only 34% were recorded premortem in the clinician's death summary. Stroke, Vol 12, No 4,1981


Specimens of a nearly black geometric larva which afterwards proved to belong to this species, were taken last year on the 15th of July on currant and gooseberry bushes, on which they were feeding. They fed on the foliage of the black currant as well as of the red, and in fact seemed to prefer it. When first taken they answered to the following description: Length 45 in. Body tapering a little anteriorly, thicker on middle and hind segments.


Calcification and mineralization are fundamental physiological processes, yet the mechanisms of calcification, in trabecular bone and in calcified lesions in atherosclerotic calcification, are unclear. Recently, it was shown in in vitro experiments that vascular-derived mesenchymal stem cells can display self-organized calcified patterns. These patterns were attributed to activator/inhibitor dynamics in the style of Turing, with bone morphogenetic protein 2 (BMP-2) acting as an activator, and matrix GLA protein (MGP) acting as an inhibitor. Different pattern morphologies were produced by external application of the inhibitor MGP. Motivated by this qualitative activator-inhibitor dynamics, we study here a bistable form of the Gierer-Meinhardt model, with autocatalytic saturation. Through a detailed analysis in one and two dimensions, we explore the pattern formation mechanisms of steady state patterns, including their dependence on initial conditions. These patterns range from localized holes to labyrinths and localized peaks, or in other words, from dense to sparse activator distributions (respectively). We believe that an understanding of the wide spectrum of activator-inhibitor patterns discussed here is prerequisite to their biochemical control. The mechanisms of pattern formation suggest therapeutic strategies applicable to bone formation in atherosclerotic lesions in arteries (where it is pathological) and to the regeneration of trabecular bone (recapitulating normal physiological development).


Objectives. We examined the association of the coronary thrombus microbiota and relative metabolites with major adverse cardiovascular events (MACE) in hyperglycemic patients with ST segment elevation infarction (STEMI). Methods. We undertook an observational cohort study of 146 �rst STEMI patients treated with primary percutaneous coronary intervention (PPCI) and thrombus-aspiration (TA). Patients were clustered, based on admission blood glucose levels, in hyperglycemic (>140 mg/dl) and normoglycemic (<140 mg/dl). We analyzed gut and thrombus microbiota in all patients. Moreover, we assessed TMAO, CD40L and von Willebrand Factor (vWF) in coronary thrombi. Cox regressions were used for the association between Prevotellaspp and TMAO terziles and MACE. MACE endpoint at 1 year included death, re-infarction, unstable angina. we observed a signi�cantly different prevalence of both Prevotellaspp between with (n=56) and those with normal glucose levels (n=90). The abundance of Prevotella increased in hyperglycemic vs normoglycemic patients whereas the contrary was observed for Alistipes. Interestingly, coronary thrombus, the content of Prevotella was associated with admission blood glucose levels (p<0.01), thrombus dimensions (p<0.01), TMAO, CDL40 (p<0.01) and vWF (p<0.01) coronary thrombus contents. Multivariate Cox-analysis disclosed a reduced survival in patients with high levels of Prevotella and TMAO in coronary thrombus as compared to patients with low levels of Prevotella and TMAO, after 1-year follow up. statistically signi�cant. The study population was equally distributed for age (p = 0.807). To evaluate the independent contribution of hyperglycaemia in thrombus Prevotella and TMAO levels, we performed a correlation between Prevotella and TMAO levels in coronary thrombus and blood glucose level during STEMI. Risk adjusted Cox-regression analysis curves showing survival from severe disease through days of hospitalization. Cox models were adjusted for; age, diabetes, hypertension, diabetes, new diabetes, dyslipidemia, cigarette smoking, BMI, systolic blood pressure, total cholesterol, HDL and LDL-cholesterol levels, triglycerides, TIMI scores, lesions of RCA and LM, dual antiplatelet therapy and ejection fraction. To investigate the effects of Prevotella and TMAO thrombi expressions on cardiovascular endpoints, we evaluated STEMI outcomes at 1-year follow-up thrombus contents did not change despite a similar severity of atherosclerotic disease at baseline and asimilar glycemic control both at discharge and at follow-up. These observations suggest that on admission hyperglycemia may play a pivotal role in the increase of coronary thrombus burden, during STEMI, favoring thrombus colonization and proliferation by Prevotella.


Background: Periodontal regeneration therapies frequently involve autologous platelet concentrates (APCs). They can be used in sinus lift surgeries and socket preservation, among other clinical settings. Platelet rich fibrin (PRF) membrane has been used to treat gingival recession in individuals or groups of individuals using a coronally progressed or lateral pedicle flap. In the treatment of mixed periodontic endodontic lesion/furcation defect, PRF functions as a healing and interpositional biomaterial, filling a cystic cavity. PRF is known to help the bone regeneration process. In the last few years, efforts have been made to enhance the PRFs characteristics and quality. One of them is titanium platelet rich fibrin (T-PRF). Third-generation platelet concentrate no longer contains silica, and its preparation in glass vacuum containers, no longer creates any known concerns. The effectiveness PRF's has been evaluated in connective tissue and bone repair. The aim of this study is to compare T-PRF to other platelet concentrates and different treatment modalities for periodontal regenerative procedures. Methods: A protocol of this systematic review have been registered in prospero (CRD42022293545). The online database searched were PUBMED, COCHRANE for published articles up to November 2022 without language restrictions. Studies in trial registers, handsearching, bibliographic references of relevant articles were also checked. Data collection and analysis was done by individual authors. Independent eligibility assessments were conducted by four review authors. Then, using the standard Cochrane methodology, four review authors extracted the data and evaluated the risk of bias for individual studies. We developed "Summary of findings" tables and used GRADE to evaluate the evidence. Results: Three studies were included for meta-analysis. Results of meta-analysis supported that T-PRF is effective for correction of both hard and soft tissue defects. Conclusions: The overall qualitative and quantitative analysis suggest that T-PRF has superior structural properties and thicker fibrin network for periodontal regenerative procedures.


Objective To explore the effect of thoracic paravertebral block(TPVB)versus general anaesthesia(GA)on breast surgery.Methods Public databases were searched including Medline and Springer,in order to collect randomized controlled trial(RCT)of the effects of TPVB and GA on breast surgery.The data of the meta-analysis was analyzed by Stata 11.0and RevMan 5.1.Results There were five RCTs consisting of 295 patients with breast surgery,group TPVB(n=148)and group GA(n=147).The overall results of meta-analysis showed that pain scores of group TPVB were higher than those of group GA for breast surgery patients(SMD 2.59,95%CI 1.10-4.08),but the postoperative analgesic consumption and postoperative nausea or vomiting of group TPVB were lower than those of group G(RR 0.23,95%CI 0.15-0.37 and RR 0.27,95%CI 0.12-0.61,respectively).Conclusion Compared with GA,TPVB has higher pain scores,lower postoperative analgesic consumption and postoperative nausea or vomiting.

In 2021, the Shanghai Cooperation Organization (SCO) will celebrate its 20-year anniversary. Transformed from the "Shanghai Five" mechanism on settlement of border disputes and confidence-building between four ex-soviet republics Russia, Kazakhstan, Kyrgyzstan, Tajikistan and China, into the full-fledged organization in 2001, has been become one of the important players in Eurasian region. Since then SCO has made significant progress, especially, in combating the threats of international terrorism, extremism and separatism and ensuring regional security in general. However, the SCO could not advance in the economic field that is a key for an integration and convergence of the members states with different political and economic systems. Moreover, rising tensions between some members, namely India and China, as well as pandemic crisis and current geopolitical uncertainties in Eurasia may further exacerbate the situation within the Organization. What path can the SCO take in the future? Will its agenda have changes? Will there be institutional reforms in the organization? What will be the role of the SCO in shaping the new multipolar world order and in the region? These are the questions, which are now circulating around the SCO.


Preterm deliveries is the major contributors of neonatal mortalities and under 5 age group morbidities. Excessive use of Progesterone and its supplements, antenatal steroidal cover and tocolysis prevents this. In this study, there has been made an attempt to study the perinatal outcome of both mother and neonate revolving around premature deliveries by using two different routes for progesterone administration. A prospective study was done on randomly selected 300 patients who complained of pain abdomen after 24 weeks of pregnancy, and were followed up till delivery after administration of progesterone, after dividing into 2 separate groups. This leads to collection of data for interpretation of association of variation in various parameters with relation to use of different routes for micronized progesterone. When compared, users of Oral micronized progesterone (OMP) presented at 31.37±1.94 weeks for delivery and that of Vaginal micronized progesterone (VMP) presented at 33.49±2.49 weeks of gestation. 78.7% neonates of Oral group were asymptomatic at birth than those 90.7% of vaginal neonates. Incidence of neonatal morbidity, like signs of birth asphyxia (16.7% vs 3.3%), mean APGAR Score of 1 min (7.77±2.11 vs. 8.07±1.63), mean birth weight (2.89±0.67 vs. 3.19±0.61), NICU admission (13.3% vs 3.3%) were found to be higher in Oral group than Vaginal group. Administration of Vaginal micronized progesterone helps in reduction of preterm labor and the rate of neonatal NICU admissions, neonatal mortality and morbidity as compared to oral micronized progesterone. Vaginal progesterone surpasses the first pass metabolism explaining the better outcome of the vaginal in preventing preterm labor.


This project aims to cover the development of multiple scenarios for controlling autonomous
vehicles, with the goal of providing autonomous cars that will be able to handle
complex situations in trac. The scenarios are developed on the Gulliver-platform, a platform
of autonomous miniature vehicles currently in development at Chalmers University of
Technology. Two scenarios are realized, cruise control and autonomous driving through an
intersection without trac lights. The scenarios utilizes both sensors and car-to-car communication.
Furthermore, in order to evaluate the developed scenarios before implementing
them on the physical testbed, a simulator capable of simulating sensors, communication
and vehicular movement is required and developed.


BACKGROUND AND OBJECTIVES
The amount of root coverage obtained after a graft procedure may be improved after the early phase of healing by a coronal displacement of the gingival attachment. The aim of this report is to present a clinical case of complete root coverage of a Miller's class IV recession achieved by creeping attachment subsequent to a laterally repositioned flap.

METHODS
In 1995, a 44-year-old male patient was referred for a root coverage graft on the upper right central incisor. Clinical examination revealed that the upper right central incisor had a recession of 7 mm. The defect was classified as class IV according to Miller's classification of marginal tissue recession. It was decided that root coverage would be attempted using a laterally repositioned flap from the upper right lateral incisor and upper right canine. Sutures were removed ten days after surgery.

RESULTS
Four months after grafting, the amount of root coverage obtained was 4 mm. After an 8-year period, the previously denuded root surfaces were entirely covered by soft tissue. The marginal position of the gingiva appeared stable, the gingival tissue became firmly attached to the root surface and probing showed a shallow sulcular depth.

CONCLUSION
Several interesting observations were made after 8 years. In conclusion, the most significant and interesting finding of this report is that the amount of interdental papilla and marginal gingival tissue covering donor and recipient areas improved with time, providing an excellent aesthetic appearance.


The process at the emergency department is complex. Every patient that arrives at the emergency department comes unexpectedly and follows a unique and changeable trajectory of care events. It is very difficult to analyze and improve such a complex process. One way of understanding and improving the process of the emergency department without actually changing the real life system is simulation. In this research simulation was used to design scenarios with help of theory and practice. From practice we designed scenarios who support the redesign of the process at the emergency department in Amsterdam. Scenarios designed
through meetings with working staff are implemented into an excisting simulation model of the emergency department of Amsterdam. At the emergency department in Amsterdam a new
working method will be introduced consisting of a triage-nurse. The purpose of this new method is to improve the patient flow and thus increase patient satisfaction through the reduction of length of stay. Simulation can support the introduction of this new method. Simulating a triage nurse who can initiate direct supplementary diagnostics showed really promising results.


Thirty years ago, Noam Chomsky and Edward Herman published their book Manufacturing Consent: The Political Economy of Mass Media (1988). The World Wide Web had not yet been invented and internet use was neither common nor widespread. Today, notions of propaganda are not widely shard and tend to sound strange to our ears. Also the notion of the mass media has been replaced by speaking of the media in general, which is due to the fact that digital media, such as the internet, have integrated interpersonal communication, group communication, organisational communication and public communication at the level of society in one communication technology. In this contemporary age of digital and social media, it is time to revisit and reassess Herman and Chomsky's Propaganda Model (PM). This chapter begins with reflections on concepts of propaganda and its relation to ideology. It then focuses on aspects of the Model and relates them to the realm of the internet: size/ownership/profit-orientation, advertising, powerful information sources, flak, and anti-communism. The PM reminds us of the importance of thinking critically about capitalism's dominant political economy and ideologies when we analyse the internet today. Given the power of companies such as Google and Facebook, we must consider the role of new monopolies, digital labour, targeted advertising, asymmetric attention and visibility, and online ideologies when critically analysing digital capitalism.


Three methods were adopted in culture spermatogoniums of newly born calf in vitro, such as enzymatic digestion and percoll density gradient centrifugation (Method Ⅰ), tubular fragments culture (Method Ⅱ) and tissue culture (Method Ⅲ), and cultural behaviors of cells were observed. The results showed that typical spermatogonium colonies appeard at 144 h of culture by enzymatic digestion-percoll density gradient centrifugation method and tubular fragments culture method, 2.5% FBS kept the characteristics of spermatogonium stem cell better than others, produced more mass clones, and FBS of more than 2.5% concentration benefited spermatogonium differentiation and the number of colonies was significantly affected by FBS concentration. After 1 week of culture in method Ⅲ, the diameter of lumens and quantity of sertoli's cells in tubal wall increased obviously, lumen of seminiferous tubules appeared. Sertoli's cells kept constant and the number of spermatogoniums decreased obviously afier 2 weeks of culture.


One of the most challenging issues in adaptive control of robot manipulators with kinematic uncertainties is requirement of the inverse of Jacobian matrix in regressor form. This requirement is inevitable in the case of the control of parallel robots, whose dynamic equations are written directly in the task space. In this paper, an adaptive controller is designed for parallel robots based on representation of Jacobian matrix in regressor form, such that asymptotic trajectory tracking is ensured. The main idea is separation of determinant and adjugate of Jacobian matrix and then organize new regressor forms. Simulation and experimental results on a 2--DOF R\underline{P}R and 3--DOF redundant cable driven robot, verify promising performance of the proposed methods.

Abstract Students with both academic and behavioral risk factors can benefit from participation in self-regulated strategy development (SRSD) instruction. Educators can use systematic screening procedures as part of effective data-informed decision making for identifying students who could benefit from SRSD. In this manuscript we detail screening procedures for both academic and behavioral risk factors to connect identified students with SRSD instruction. Recommendations for screening practices are provided including future directions for research.


Hume's theory of intellectual and emotional understanding of the premise and its moral values of justice has laid a strong foundation for the theory.From the origin of justice,justice derived from the selfish and the natural human needs provided by the lack of supply.Selfishness is the original motives,and our sympathy and moral approval of justice said the source.From the nature of justice,justice is due to meet the human needs of the environment and used by man-made or design,therefore,belong to intended moral.
