Covalent organic frameworks (COFs) are novel crystalline polymers with a unique designable feature at molecular level via weaving chemistry. 2D COFs with a variety of ordered π systems provide a desirable platform for developing visible-light responsive photocatalysts for solar energy storage and conversion and have already shown potential applications in photocatalytic water splitting, CO2 reduction, and organic synthesis. In regardless of suitable bandgap and band structure, COFs in most cases afforded very low quantum efficiency in photocatalysis. Considering that the separation and transportation of the photogenerated charges is the key step in photosynthesis, the fast extraction of photogenerated electrons confined in π orbitals of COFs is very important for efficient photosynthesis. In natural photosynthesis, the photogenerated holes and electrons are spacially separated in PS II (catalyze H2O oxidation to Hþ and O2) and PS I (photoenzymatic reduction of NAD(P)þ to NAD(P)H). The excited electrons are transferred from PS II to PS I through multistep with the assistance of mediators to inhibit the charge recombination. Inspired by natural photosynthesis, the utilization of an electron mediator is an efficient strategy to enhance the charge separation of COFs for efficient artificial photosynthesis. A good electron mediator should possess redox potentials alignment with the band structure of COFs and the properties of easy electron acception and donation. Polyoxometallates (POMs) could be reduced to heteropolyblue (HPB) via accepting electrons. More interestingly, HPB can be excited by visible and near-infrared light at about 700 nm via intervalence charge transfer to regain the energy that is lost in the reduction process and the excited HPB* facilely denotes electrons to electron acceptors, e.g., Hþ, O2, and metal complexes to drive the photocatalytic reductive reactions. Previous studies showed that the photocatalytic activity of semiconductors, e.g., C3N4, TiO2 were greatly promoted by coupling with POM in photocatalytic CO2 reduction, water oxidation, and organic pollutants removal due to the enhanced charge separation. Though POM is a good candidate as electron mediator and electron storage tank, the coupling of COFs and POM has not been reported yet for artificial photosynthesis as far as we know, possibly related with the difficulty in hybridizing of the POM and COFs. Herein, we report the fabrication of nanoCOF/POM composites for the first time by simply mixing the cetyltrimethylammonium bromide/sodium dodecyl sulfate (CTAB/SDS, molar ratio of 97/3) micelle stabilized nanoCOF colloid solution with Na3PW12O40 (Scheme 1). NanoCOF/POM composites possess visible-light responsive properties inherited from nanoTp-TTA COF (synthesized using 1,3,5-triformylphloroglucinol and 4,4 0,4 00-(1,3,5-triazine-2,4,6-triyl)trianiline as precursors).

The paper aims to model the performance of the Glass Fibre Reinforced Epoxy (GRE) composite pipe under multiaxial loading via system identification approach. System identification modelling depends on the input and output data of the experimental result. In this study, the experimental data used are obtained from a pressurised test rig. The model is based on pure hydrostatic (2H: 1A) loading using GRE pipes with three different winding angles (±45 °, ±55 °, ±63 °). Several models based on different model structures are derived for comparison to obtain the best modelling accuracy. The result shows that the transfer function method could model and has the highest efficiency compared with the experimental result. The ±45 ° pipe model have achieved 92.41% and 85.13% for both its hoop and axial model. The ±55 ° pipe model has achieved 96.64% and 86.1%. Follow by the ±63° which the best fit is 92.41% and 94.26%. At the last part of this research, the ±55° pipe model and experimental data has been use to identified when the damage occur and found that the axial strain of 78 bar can damage the experimental pipe in this research.The paper aims to model the performance of the Glass Fibre Reinforced Epoxy (GRE) composite pipe under multiaxial loading via system identification approach.

This paper proposes EventCluster, a novel approach in real-time data modeling. It deploys the Rank Order Clustering (ROC) method to automatically group all existing data sensors and actuators of the system to the Key Performance Indicators of the system. EventCluster (EC) is a cause-effect relationship data clustering tool that detects the interrelationship between field data and system performance parameters in real-time. Through its simple data filtering mechanism it can be used as a precursor to real-time sensitivity analysis. The underpinning logic of the technique is that the raw data can be obtained from field data acquisition devices and the degree of their influence on key system performance indicators can be measured in realtime with minimum computational effort. Normally monitoring and control systems are equipped with sensors and actuators that provide information for a pre-specified function regardless of other parts of the system. The global assumption of method is that a system performance or state is a function of all the inputs of the system, unless proven otherwise. In the proposed method all the inputs and outputs of the system are assumed to affect one another unless proven otherwise. In this paper, an experiment in Cement Kiln operation case demonstrates the suitability and applicability of EventClustering modeling method in industrial applications. We use the Supervisory Control and Data Acquisition (SCADA) sensors and actuators installed to monitor the operations of Kilns in Cement manufacturing process and its contagious operations as a case study for proof of concept. The sensors and actuators data collected builds the input data for measuring the performance (output) of the Kiln. The EventCluster algorithm resides within the control center of the SCADA system to assess the contribution of each input to the overall key performance indicators (output) of the process. This method improves the quality of data analysis and reduces computation overhead on the control system.

Future projections of energy sources to meet the needs for electric power generation predict that coal will be a major fuel source. However, government-imposed limitations on emission levels of particulates, sulfur and nitrogen oxides make compliance by conventional coal fired units almost impossible. Alternate approaches which are currently receiving considerable attention employ air-blown coal gasification and gas cleaning followed by second stage burning. Paramount in the design of such cycles is the ability to accurately predict the product gas quality exiting from the coal gasifier. Operational data from a 5000 sctm atmospheric pressure air-blown suspension type slagging coal fired gasifier are presented. A correlation of these data shows this process is kinetically controlled and that the product gas heating value (Btu/scf) can be predicted using on a term defined as heat available (Btu/lb air imput) which is a function of (1) coal analysis, (2) air preheat, (3) char recycle rate, and (4) heat losses.

The invention discloses an ophthalmic imaging diagnostic system which comprises an eyepiece and an OCT imaging module. The OCT imaging module includes a fundus OCT imaging mode and an anterior segmentOCT imaging mode. The OCT imaging module in the fundus OCT imaging mode has a first intermediate image plane. The first intermediate image plane is located between the eyepiece and the OCT imaging module; and a lens group is arranged in an internal optical path of the OCT imaging module in the fundus OCT imaging mode. The OCT imaging module has a second intermediate image plane located in the OCTimaging module, and a conjugate position of an imaging optical path aperture diaphragm of the OCT imaging module is located between the eyepiece and the OCT imaging module, to obtain the anterior segment OCT imaging mode. The ophthalmic imaging diagnostic system has functions of fundus OCT imaging and anterior segment OCT imaging, and the internal switching of the fundus OCT imaging and the anterior segment OCT imaging is implemented. After the fundus imaging is switched to the anterior segment imaging, a second intermediate image is added in the OCT imaging module. The method enables the angle of incidence of light to the anterior segment to be controlled more flexibly, and the anterior segment field resolution index can be improved. The switching is performed in the optical path of theOCT imaging module, and no influence is generated on other system optical paths in the switching process.


Automated plant identification enables experts to process significantly greater numbers of plants with higher efficiencies in shorter periods. It is time-consuming and difficult to determine the name of species based on observations, even for botanist experts. However, plant recognition is a kind of fine-grained visual recognition problem, which is relatively harder than conventional image recognition. To solve this problem, we present a solution that transfers the learning information from a Deep Convolutional Neural Network (DCNN) trained on the ImageNet database, which contains millions of images, for automated plant identification based on flower and fruit images. First, we modify the last three layers of the pre-trained network to adapt ResNet-50 model to our classification task and replace the fully connected layer in the original pre-trained network with another fully connected layer, in which the output size represents the class of plants. Second, we use transfer experience and fine-tuned pre-trained DCNN for experiments using flower and fruit images. Finally, we evaluate the proposed network on two available botanical datasets: the Oxford flowers dataset with 102 classes and the HNPlant flowers and fruits dataset with 20 classes and determine the optimal values of the associated hyperparameters to improve the overall performance. Experiment results demonstrate that the highest classification accuracies exhibited by the proposed model on the Oxford-102 and HNPlant-20 datasets are 92.4% and 95.0%, respectively, thus establishing their effectiveness and superiority.


This study aimed to develop manipulative learning media based on STEM (Science, Technology, Engineering, and Mathematics) called Magic Hours on Clock and Corner material. Research and development model used by using the procedure of Analysis, Design, Development, Implementation, and Evaluation (ADDIE). The population of this study was all 4th grade students from elementary school in Kediri. Due to the Covid-19 Pandemic situation and study from home policy, manipulative media was tested on 13 fourth grade elementary school students in Kediri who came from the same village to reduce students' mobility from one place to another. Data collection techniques are collecting through expert validation, teacher questionnaires, student questionnaires, test, observation, and interviews. The instruments are test (description questions) and non-test instruments (material validation sheets, design validation sheets, practicality assessment sheets, questionnaire validation sheet, and questionnaires). The result shows that the learning media are valid, practical, and effective. Learning media have feasible criteria with an assessment score of 88.46% from media experts and 86.67% from material experts. In the practicality test, learning media obtained a percentage of 86.67% with practical criteria. The result of a one-sample t-test on student test scores indicates that the average mathematics score test is significantly more than Minimum Completeness Criteria.


of courtroom talk is radically not like making sense out of other forms of talk. This aspect of reconstructing reality in the courtroom is ignored in an analysis that emphasizes similarities between talk in court and stories. I agree with the authors that it is important to point out that somewhat different kinds of activities may involve similar social processes. But relating trials to stories in particular accomplishes no clear end and ignores and obscures the very important ways in which interpretative processes in courtrooms are significantly different from those in other settings within our society.


With the advent of magnetic gears, researchers have developed a new breed of permanent-magnet machines. These magneticgeared permanent-magnet machines artfully incorporate the concept of magnetic gearing into the permanent-magnet machines, leading to achieve low-speed high-torque direct-drive operation.Gears and gearboxes are extensively used for speed change and torque transmission in various industrial applications. It is well known that the mechanical gear has a high torque density, but suffers from some inherent problems such as contact friction, noise, heat, vibration and reliability are of great concern. In order to avoid these types of problems we are using magnetic meshing gears. That is the gears are meshed together with the help of magnetic force of attraction without making into contact. By using such kind of gearing systems we can reduce the wear and tear that are commonly seen in mechanical spur gear systems and the magnetic gears works smoothly without any sound and the main advantage of magnetic gearing is it will not get heated as long as it works. Magnetic gearing systems can be used in vehicle transmissions that reduce the friction and improve the efficiency without using any type of additional lubricants. We are using high power rare earth neodymium magnets for the purpose of making gears. Neodymium magnets are powerful magnets which are about 12 times stronger than normal magnets used in speakers.


The Green's function method has been used to study the energy bands of Cu for two quite different potentials. It is found that the resulting $E(\mathrm{k})$ for the two cases are very similar throughout the Brillouin zone having the same ordering of the levels and comparable level separations in the conduction, low-lying excited, and $d$-band regions. This implies that the calculated band structure is not as sensitive as had been previously contended. The properties of the Fermi surfaces associated with the two theoretical band structures are compared with the results of experimental studies. It is found that the theoretical surfaces intersect the hexagonal zone face in accord with experiment. The computed radii of contact for the two cases are close to the measured values. Furthermore, the bellies for the two cases are shown to deviate appreciably from sphericity in agreement with the results of recent magnetoacoustic effect experiments. The origin of the distortions is explained in terms of the interaction between the conduction and $d$ bands. The "masses" defined in terms of the cyclotron resonances for various orbits on the Fermi surface, the lowtemperature electronic specific heat, and the dielectric constant in the infrared region are determined for the calculated $E(\mathrm{k})$. The calculated masses are all somewhat lower (by about 10-30%) than the corresponding measured masses. It is believed that these discrepancies reflect the contributions of the effects neglected in the individual-electron model. Finally, the sharp rise in the optical absorption, which on the basis of the theoretical $E(\mathrm{k})$ corresponds to the onset of interband transitions between the $d$ bands and the Fermi level, is found to occur at an energy in good accord with experiment.


Scientific visualization has the potential to make science education more accessible and to provide a means for authentic scientific inquiry. The role of scientific visualization within science is explicated through examples of its use and by presenting a sociological account of science that portrays scientific visualization as an important new inscriptional system. Three examples of using scientific visualization within education are provided: the Chem Viz Project at the National Center for Supercomputing Activities the image Processing for Teaching (IPT) project at the University of Arizona, and an undergraduate climatology course at the University of Chicago. Potential problems of integrating scientific visualization within secondary education are described, including student' need to learn basic scientific practices, incompatibilities between the format of the traditional high-school classroom and scientific inquiry, and the need for additional infrastructure within schools. Finally, possible solution...


Multimodal image fusion is a powerful tool in clinical applications such as nonvasive diagnosis, image guided radiotherapy and treatment planning. It has been developed with various imaging modalities in medical imaging and its main aim is to capture more relevant informations from sources to a single output. So a fusion framework is proposed for multimodal images on non sub sampled counter let transform which is proposed based on theory of counter let transform. It has many advantages of counter let transform and it effectively overcomes the wavelet transform and pseudo Gibbs phenomena. In this technique the source image is initially transformed by NSCT by fusing the low and high frequency components. In this paper, mainly two fusion rules are used-phase congruency and directive contrast. The phase congruency is used for low frequency components for improving its contrast and brightness. The directive contrast is used for high frequency which effectively determines the frequency coefficients from the clear pars in high frequencies. Finally fused image is constructed by inverse NSCT with all relevant coefficients. The image enhancement is done by using adaptive histogram equalization and image denoising is done by using Weiner filtering. The combination of these techniques can preserve more details of fused image and can improve the quality of fused images. Multimodal image fusion is a possible way to integrate complementary informations from multiple images to a single output. The image fusion not only obtain an accurate and complete description of same target ,but also reduces the randomness and redundancy to increase clinical applicability. Keywords— Non subsampled counterlet transform,directive contrast,phase congruency,adaptive histogram equalization,weiner


Hisham Palace, qasr Hisham , at Khirbet al-Mafjar is important for discussion of images in Early Islam. An exceptionally rich collection of mosaics and art works there has survived despite the ravages of time and destruction by humans seeking treasure after a massive earthquake destroyed the site in 746/747 and buried it under rubble and sand. Hamilton, the main excavator, was both fascinated and confounded by the realistic figurative art depicting living things . The general basis for the discussion of al-Walid ibn Yazid as the patron of many secular Umayyad palaces is a somewhat axiomatic acceptance that an iconoclastic Moslem prohibition against creating art of living forms was already in force during the reign of Hisham. Several leading 8th century Christian iconodule theologians saw a close connection between the rulings issued by Yazid II and Leo III and, accordingly, between Islamic and Christian iconoclasm.

In light of recent evidence suggesting a nonzero present-day cosmological constant [1], Adams, Mbonye, & Laughlin[2] have considered the evolution of black holes in the presence of vacuum energy. Using the assumption that Λ remains constant with time and a conjecture based on a paper by Mallett [3], they reach the remarkable conclusion that black holes with current mass greater than ∼ 2 × 10 −9 M ⊙ will not Hawking evaporate in the distant future, but will instead absorb vacuum energy and grow to roughly the de Sitter horizon size. In this letter we reexamine black hole evaporation in the presence of a cosmological constant, and find instead that all known black holes will eventually evaporate. It is well known that a black hole of mass M in otherwise empty spacetime radiates as a blackbody at the Hawking temperature T H = 1/(8πGM) = 6.15 × 10 −8 (M ⊙ /M)K. (1) It is also well known that inertial observers in a de Sitter universe with cosmological constant Λ feel themselves to be immersed in a bath of thermal particles at the Gibbons-Hawking temperature [4]


ABSTRACT Avian nasal mites are obligate endoparasites that spend their entire life in the respiratory system of birds. In North America, bird nasal mites are represented by several unrelated families in three orders of mites: Rhinonyssidae (Mesostigmata), Ereynetidae (Trombidiformes), and Cytoditidae and Turbinoptidae (Sarcoptiformes). The most-diverse and commonly encountered family of nasal mites is Rhinonyssidae, in which mite species may have different levels of specificity to host orders, families, or even to species. In this study, birds from Arkansas and Illinois in the United States were surveyed for nasal mites. Of 430 birds examined, 58 individuals (13.4%) and 30 of 106 bird species (28%) were infested with nasal mites. Levels of mite prevalence were similar to results reported from previous studies (25-45% of species). The 58 infested birds with nasal mites belonged to 4 orders, 11 families, 24 genera, and 30 species. Rhinonyssidae was the most commonly found family and was represented by 15 species. Nineteen new North American host records are added, the majority being found within the bird families Parulidae and Emberizidae. Three new host records are added in Turdidae and Accipitridae with nasal mites from the families Ereynetidae and Turbinoptidae.

A slender, axisymmetric inclusion of a highly viscous fluid is deformed by an external Stokes flow. The method of matched asymptotic expansions is used, and boundary conditions for the outer flow are found in terms of the cross-sectional area of the inclusion and its local extensional velocity along the axis. This problem is then formulated as an integral equation for which an exact solution is found. was considered. In this paper we will only be concerned with the problem in the absence of surface tension. In this case advances were made by Eshelby (2) and Bilby and Kolbuszewski (3) on the two-dimensional, time-dependent problem when exact solutions were found corresponding to an inclusion that maintains an elliptic profile as it deforms. Still in two dimensions, but when the inclusion is thin and of arbitrary initial profile, asymptotic results for the evolution of the inclusion were found by Spence et al. (4), Wilmott (5), and Spence and Wilmott (6). Less work has been done on the three-dimensional problem, but exact solutions have been found by Bilby, Eshelby, and Kundu (7), and by Howard and Brierley (8) when the inclusion is a deforming ellipsoid. In this paper we extend the work of Wilmott (5) (the two- dimensional case) to consider the slender, axisymmetric inclusion of arbitrary initial cross section. In ? 2 we introduce the governing equations, boundary conditions, and scalings and find the inner solution in ? 3. The behavior of the outer solution is examined in ? 4 and this is represented by a singularity distribution along the inclusion axis. The matching procedure then leads to an integral equation for the evolution of the inclusion. An exact solution to this equation is found in ? 5. 2. Mathemitical analysis. Into an axisymmetric Stokes flow of a fluid of large viscosity ,u is introduced as a slender, viscous, axisymmetric inclusion of viscosity -j


We analysed geographic variation in the number of males per 100 females at birth also called the secondary sex ratio (SR), the crude birth rate (CBR), the total fertility rate (TFR) and the tw inning rate (TWR). Earlier studies have noted geographic variations in the TWR and racial differences in the SR. Statistical analyses have shown that comparisons between SRs demand large data sets because random fluctuations in moderate data are marked. Co nsequently, reliable results presuppose national birth data. In this study, we analysed historical demographic data and investigated the geographic variations between the counties in Sweden for the SR among the live born (1749 - 1869), the CBR in 1751 - 1870, the TFR in 1860 and the TWR in 1751 - 1860. We built spatial models and as regressors we used geographic co - ordinates for the residences of the counties in Sweden. The influence of the CBR and TFR on the SR and TWR was examined. For all variables, we obtaine d spatial variations, albeit of different patterns and power. Hence, no common spatial pattern for the demographic variables SR, TFR, CBR and TWR was detected, but a better fit was noted for TFR, CBR and TWR than for SR.


At the time of this meeting, the latest Gaia data release is EDR3, published on 3 December 2020, but the next one, DR3, will appear soon, on 13 June 2022. This contribution describes, on the one hand, Gaia EDR3 results on massive stars and young stellar clusters, placing special emphasis on how a correct treatment of the astrometric and photometric calibration yields results that are simultaneously precise and accurate. On the other hand, it gives a brief description of the exciting results we can expect from Gaia DR3.

This experimental investigation deals with the fabrication of boron carbide (B4C) particulates reinforced Nickel based Waspaloy (WA) composite. The bottom pouring type stir casting machine under argon atmosphere was used to prepare the composites. B4C content was reinforced with Nickel based WA in the weight basis (0, 4, 8 and 12 %). The microstructure of the prepared composites was studied by using SEM and EDS. The tensile strength, impact strength, hardness and density of the samples have been reported. Then the Pin on Disc (POD) setup was used to study the wear performance of the samples. The wear parameters were analyzed by using Grey relational analysis (GRA) for the low specific wear rate (SWR) and coefficient of friction (COF) for produced composites. The addition of B4C improved the mechanical properties of the sample up to 8% and then tends to decreases. Analysis of variance (ANOVA) showed that, load is the most dominant parameter which affects the SWR of the composite. From the GRA, Load 20 N, sliding speed 1146 rpm, 12% B4C are found to be optimum parameters for minimum SWR and COF.

The reaction between RuCl3 and PiPr2Me in 2-methoxyethanol yielded the five-co-ordinate complex [RuCl2(CO)(PiPr2Me)2] in which the phosphine groups show a cisoid arrangement. The co-ordination sphere of the ruthenium nucleus can be completed with neutral ligands such as CO, tBuNC, Hpz, 3,5-dimethylpyrazole and HNCPh2. Likewise, it reacts with S-donor reagents like PhSH and 2-sulfanylpyridine and readily undergoes metathesis reactions with salts of some chelating ligands like NaS2CNEt2, KS2COR (R = Me, Et or iPr) and K(acac) which are bonded in a bidentate mode.


Concentrated fresh juice of bamboo shoots was filtered through a Sephadex G-75 column under aseptic and anaerobic conditions. The detinning activity in the filtrate was assayed by an oxygen monitor in the presence of tin powder. A large amount of peptides with molecular weights about 1300, some nucleotides and p-hydroxybenzaldehyde were identified as the detinning substances. Twenty peptides were isolated by means of cation and anion exchange chromatography. The primary structures of these peptides were elucidated by the subtractive Edman degradation, in which a high performance liquid chromatograph was used for amino acid and sugar analysis.


The degree of complexity and, to a somewhat lesser degree, realism in simulations has advanced rapidly in the past few years. The simplest approach - modeling a cluster as collisionless dark matter and collisonal, non--radiative gas is now fairly well established. One of the most fruitful results of this approach is the {\sl morphology--cosmology connection} for X-ray clusters. Simulations have provided the means to make concrete predictions for the X-ray morphologies of clusters in cosmologies with different $\Omega_o$, with the result that low $\Omega_o$ cosmologies fair rather poorly when compared to observations. Another result concerns the accuracy of \xray binding mass estimates. The standard, hydrostatic, isothermal model estimator is found to be accurate to typically better than $50\%$ at radii where the density contrast is between $10^2$ and $10^3$. More complicated approaches, which attempt to explicitly follow galaxy formation within the proto--cluster environment are slowly being realized. The key issue of {\sl dynamical biasing} of the galaxy population within a cluster is being probed, but conclusive answers are lacking. The dynamics of multi--phase gas, including conversion of cold, dense gas into stars and the feedback therefrom, is the largest obstacle hindering progress. An example demonstrating the state--of--the--art in this area is presented.


In the context of evaluation and accountability policies in the public municipal school network in Rio de Janeiro, this article deals with three studies based on observations and interviews conducted in one public school in the network and exploratory inroads about the data from the contextual questionnaires of the directors of the 2007, 2009 and 2011 Prova Brasil. The increasing challenges and tensions present in the agenda of school management are discussed, highlighting the bureaucratic work overload in a context of the precarious conditions of administration, of a tense mediation of the policies together with the school agents and, also, the trends of changes in school management. It concludes by highlighting the importance of the consolidation of thinking about research, and the preparation of school management in the face of the new political and pedagogical changes, without losing sight of their administrative and politico-legal limitations.


The teaching and learning process that is happening right now really needs more attention from teachers and parents considering the COVID-19 pandemic which requires students to study at home. All of that certainly cannot be separated from the involvement of teachers in Islamic religious education. The objectives of this research are: 1) How is the existence of Islamic religious education teachers in the learning process for students facing the covid 19 pandemic in Lhokseumawe City?. 2) What is the pattern of Islamic Religious Education teachers in providing the learning process during the COVID-19 pandemic in Lhokseumawe City?. The research approach used is qualitative with the type of field study (field research), while the data collection method uses observation, interviews, and documentation. As for the data analysis technique using data reduction, data presentation and drawing conclusions. From the results of this study, it was found that: 1) The existence of Islamic religious education teachers in improving the learning process for students facing the covid 19 pandemic in Lhokseumawe City was not carried out properly, because existing facilities and learning media for Islamic religious education were incomplete, making the learning process only takes place in a few weeks and even then outside of the role of a teacher that should be done, because teachers do not use schedules, syllabus or lesson plans during the covid period, only revolve around sending modules in the form of learning materials and assignments. 2) The pattern of teachers providing an understanding of Islamic religious education learning for children facing the COVID-19 pandemic in Lhokseumawe City is carried out in two ways, namely through direct visits to students' homes and providing an understanding of the learning process during the COVID-19 pandemic for teachers in Lhokseumawe City by using an online pattern (in the network). With this pattern the learning process can be carried out without face to face even though there are obstacles such as the internet network.

In this research work, we investigate the effects of cybercrime and focus on concerns about cybercrime expansion. Since black-hat hackers are constantly one step ahead of white-hat hackers and exploit new sophisticated hack-tools to intrude to devices and networks to commit cybercrime for different reasons, the utilization of the available emerging technologies can provide better privacy and protection level, while they can be used to combat cybercriminal attacks. This shift to new technologies and methods is regarded to be an urgent necessity today. Therefore, we demonstrate a potential novel security mechanism for Police Authorities, named "Artificial Intelligence ANTi-Attack System" or simply "AIANTAS" that aspires to improve the detection rate of cybercriminals and lead to their faster arrest. This model can be integrated into the other National Security defense mechanisms both in Greece and worldwide.


The effect of chitosan coating in fresh-cut mushroom preservation, including microbiological, enzyme activities, colour characteristics and chemical quality attributes, was examined. However, application of chitosan coating to enzyme activity control and quality maintenance of fresh-cut mushroom was investigated. Fresh-cut mushroom were treated with aqueous solution containing 5, 10 and 20 g of chitosan/1 L, placed in polyethylene bags, and then stored at 4°C. Changes in total phenolic content, and cellulase (CEL), total amylase, α and β amylase, laccase (LAC), phenylalanine ammonia lyase (PAL), peroxidase (POD), catalase (CAT) and polyphenoloxidase (PPO) enzymes activities were measured. Applications of chitosan coating delayed discoloration associated with reduced enzyme activities of LAC, PAL, POD, CAT and PPO as well as lowered total phenolic content. Also, it slowed down texture changes associated with reduced enzyme activities of CEL, total amylase and α-amylase. Results showed that increasing the concentration of chitosan coating resulted in higher contents of total soluble solids (TSS), total acidity and TSS/T acid ratio of fresh-cut mushroom. In mushroom, during storage at 4°C for 15 days, 20 g/kg chitosan coating inhibited the growth of total bacteria, yeasts and moulds counts. Chitosan also had a good effect on the evolution of the colour characteristics and parameters (C* and BI) of fresh-cut mushroom during storage at 4°C. The results showed that increasing the concentration of chitosan coating enhanced the beneficial effects of chitosan on extended shelf-life and maintained quality of fresh-cut mushroom.


Biomarkers have a growing role in clinical trials. With the advent of the targeted therapy era, molecular biomarkers in particular are becoming increasingly important within both clinical research and clinical practice. This article focuses on biomarkers that anticipate the prognosis of individual patients ('prognostic' biomarkers) and on biomarkers that predict how individual patients will respond to specific treatments ('predictive' biomarkers, also called 'effect modifiers'). Specific Phase II and III clinical trial designs are discussed in detail for their ability to validate the biomarker and/or to establish the effect of an experimental therapy in patient populations defined by the presence or absence of the biomarker. Contemporary biomarker-based clinical trials in oncology are used as examples.


Unethical aggressive behaviour in defined as illegal and unlawful attack of suspects and members of the public by Nigeria Police Officers and men. Previous studies have focused on social and administrative unethical behaviour among police while affective aspect of police unethical aggressive behaviour has not been fully explored in research, therefore, this study examine the moderating role of emotional in the association between extraversion and unethical aggressive behaviour among police officers and men. Multi-stage sampling technique was use to recruit a sample of 391 serving policemen and women (Commissioned and Non-Commissioned) of Nigeria Police Force. Three self-reported measuring Instruments were used to generate data from participants. The data were analysed through the use of SPSS version 20 employing hierarchical regression and univariate analysis of variance. The result shows that emotional intelligence contributed a significant portion of changes on unethical aggressive behaviour, likewise extraversion personality trait was found to be responsible for significant portion of variance on unethical aggressive behaviour among Nigeria police officers and men. The interaction of emotional intelligence and extraversion was also found to account for significant variation on unethical aggressive behaviour. Emotional intelligence was observed as a significant moderator of relationship between extraversion and unethical aggressive behaviour. Considering the potential role of emotional intelligence and extraversion in this study, periodic assessment and training on emotional intelligence and extraversion personality trait is recommended for Nigeria police personnel. The scale measures four areas of emotional intelligence: self-awareness, self-management, social awareness and relationship The response format was rated on six-Likert response format ranging from to 6=always. The scale was revalidated in this study for cultural relativity and Cronbach coefficient alpha of 0.92 was recorded with N=391, and the standard deviation (SD) study is as high emotional intelligence, while score the standard is


These fine reprinted essays spanning the years from 1953 to 1986 demonstrate the importance of Lincoln for understanding American history as a whole and show professional scholarship at its best. They also suggest the need, perhaps, to question that scholarship in substance and style. The topics covered range from essays on historical method determining what in fact Lincoln did say and how historians figure that out, to narrow issues such as the use of the post office in politics, Lincoln's reading of Shakespeare, his relationship with Chicago's John Wentworth, and the unraveling of the Minor hoax purporting to prove Lincoln's love for Ann Rutledge. In addition Fehrenbacher sets the context for Lincoln's rise to the presidency in essays on the Mexican War, the nomination and the election of 1860. He also includes here his subtle and imaginative essays on Lincoln's relationship to Blacks, to the Constitution, and, most challenging of all, the "Paradoxes of Freedom" during the Civil War. But the core of the book is the Lincoln historiography which Fehrenbacher both discusses and illustrates. His range is wide, covering not only professional historians but also fiction writers and the "anti-Lincoln tradition." Here Fehrenbacher also assesses the value of "the new political history," and psychohistory in advancing our understanding of Lincoln and his times. Anyone who wants to understand mid-nineteenth-century America, this nation's greatest crisis, and the nation's most compelling figure needs to have these essays in hand. That is another way of saying that the Lincoln theme is ever green and hence abidingly important, and we can thank Fehrenbacher for illustrating it. Lincoln historiography interweaves with the major themes of nineteenth and twentieth-century history but it has certain unique qualities. Lincoln matters to the public as well as to scholars. His influence abides both for what he said and did as well as for what his life and thoughts can be made to say. A quote from Lincoln, an assertion that he would have agreed with me, understood my position, favored my goals, has biblical authority. Nothing in the


We examine decoding structure for distributed space-time coded regenerative relay networks. Given the possible demodulation error at the regenerative relays, we provide a general framework of error aware decoder, where the receiver exploits the demodulation error probability of relays to improve the system performance. Considering the high computational complexity of optimal Maximum Likelihood (ML) decoder, we also propose two low-complexity decoders, Max-Log decoder and Max-Log-Sphere decoder. Computational complexities of these three decoders are also analyzed. Simulation results show that error aware decoders can improve system performance greatly without high system overload and Max-Log decoder and Max-Log-Sphere decoder can drastically reduce the decoding complexity with negligible performance degradation.

The global economic meltdown is a serious worldwide malfunctioning economic activity that started in the United States of America in December, 2000 but became obvious in 2007 and fullblown between 2008 and 2009. The meltdown is characterized by drastic streamlining, rightsizing and downsizing of human and financial resources in both public and private sectors of the American economy. This paper sets out to identify the challenges the global economic meltdown poses to teacher education in Nigeria and also seeks means of handling such challenges. To have a broad understanding of the challenges the global economic meltdown have posed to teacher education, the next section of this paper highlights the meltdown as part of the global radical changes in environmental, economic, political, technological and social spheres since the beginning of this millennium. The paper concluded with recommendation of how teacher education can be made relevant for sustainable development.


In "Dream Worlds", Rosalind Williams examines the origins and moral implications of consumer society, providing a cultural history of its emergence in late nineteenth-century France.


Using domestic student teaching assistants (SAs) in the ESOL classroom has been widely accepted as an effective tool for enhancing student learning. SAs have been shown to facilitate student participation in the classroom, foster students' confidence in interacting with native speakers, and serve as a connection to the local culture (Lynch & Anderson, 2001). To capitalize on the benefits afforded by SAs, the AEC has, since 2007, integrated SAs into level one courses. However, research literature underscores that, to maximize SA efficacy, SAs must be purposefully trained for their roles (Gube & Phillipson, 2011; Kachi & Choon-hwa, 2001; Underhill & McDonald, 2010; Williams, 1991). As new GTAs, we observed that the AEC's SAs represent a broad range of personalities, facilities, and experiences. Given these variances in SAs' skills, we found ourselves questioning to what standard of knowledge we could and should hold them. Defining such a standard would enable teachers to design class activities that most productively draw upon the strengths of SAs without overstepping the boundaries of their expertise. Three lines of inquiry arose out of this realization: 1) What are the expectations of SAs at the AEC? 2) Do the AEC's current, procedure-focused SA training practices satisfactorily prepare SAs to meet these expectations? If not, 3) how can the training program be improved to make the presence of SAs in the classroom more fruitful for students, teachers, and SAs alike?


In the title compound, [Pd(C6H7N2O3)2(C2H8N2)]·5.5H2O, the Pd atom is coordinated by two 1,3-dimethylbarbiturate anions through a deprotonated tetrahedral carbon and the enolate oxygen. The Pd—N bond length of 2.078 (2) A trans to the C atom is shorter than the Pt—N distance of 2.098 (3) A in the Pt analog.


The publication of this work is a landmark event. Leading cosmetic dermatologic surgeons with international interspecialty recognition have contributed their insights and shared their surgical techniques in well-referenced chapters. All of the editors are board certified dermatologists with major interests and skills in cosmetic dermatologic surgery. The book succeeds in conveying the exciting nature of this growing subject area to the reader. This book will become a leading general reference work for cosmetic dermatologic surgeons. It will help to introduce medical students and residents to the theory and practice of cosmetic dermatologic surgery, and it will also be helpful to more experienced dermatologic cosmetic surgeons. Those practicing cosmetic surgery in other specialties should also find this textbook worthwhile.


definite conclusion it is of immediate, urgent importance that our leadership, in churches, schools and other instruments of public opinion should have an authoritative source from which to gain an understanding of the issues now before us. For that purpose this volume is well fitted. It is the best source available at this time. Merle Davis' large volume is more comprehensive of the history of the struggle for religious freedom but it is somewhat cumbersome and at a number of points is lacking in that clear discernment which is needed for the present crisis and which is manifest in Dr. Dawson's volume. The volume begins with the grounds for the opposition in our country to the union of church and state and follows this up with a chapter which shows the drift toward churchstate union. Next it turns to America's stake in her public schools, which are just now the immediate point of attack on the part of the Catholic authorities. From that point on the book discusses the various problems involved, the proper methods of procedure and the world responsibility for our standing by, clarifying and propagating this fundamental principle. An extended appendix sets out distinctly "authentic Roman Catholic pronouncements," quotes from the "Roman Catholic Spanish Catechism," gives the Roman doctrine of freedom of worship and their position with reference to education and the matter of tolerance. All this is from Roman Catholic sources. A second appendix quotes "a Manifesto of Protestants and Americans United for the Separation of Church and State." W. O. Carver

According to the World Health Organization (WHO), about 2.1 million children under the age of 15 were infected with the Human Immunodeficiency Virus (HIV) in 2015. The introduction of combined antiretroviral therapy (CART) has changed the natural history of Patients infected with HIV. Chronic diseases associated with HIV infection have taken a more prominent role in relation to acute infections. This literature review aims to systematize the complications associated with HIV infection in the pediatric age (defined by the WHO as that between birth and 19 years) in two large groups: infectious diseases and non-infectious diseases. In the group of infectious diseases, it is intended to emphasize the most prevalent infections in the pediatric age, while in the group of non-infectious diseases we aim to present the main complications by organs and systems. The search engine used to conduct the search was the PubMed and The Pediatric Infectious Disease Journal. In this paper, HIV infection is treated as a systemic infection, with the direct consequences of infection per se and the indirect consequences associated with the introduction of CART. The main complications are infectious, mucocutaneous, cardiovascular, respiratory, neurological, nephrological, gastrointestinal, otorhinolaryngological, ophthalmologic, endocrinological and neoplastic, as well as immune reconstitution syndrome associated with CART. In conclusion, the pediatric complications associated with HIV infection vary with the immunosuppression state, the transmission route, the age at infection contraction and at the introduction of CAR and the geographical location of the infected children. CART decreased the incidence of opportunistic infections and neoplasms, but paradoxically is associated with an increased incidence of immune reconstitution syndrome, cardiovascular diseases, metabolic syndrome and lipodystrophy. Early detection of complications improves the quality of life of the pediatric population. Thus, the research and training of health professionals who accompany them is crucial.


A differential pulse voltammetric method using a hanging mercury drop electrode (HMDE) was optimized for the determination of 5-dodecylsalicylaldoxime in hydro-alcoholic solutions using factorial and central composite designs. The Taguchi design methodology was used to extend the formerly optimized method to the determination of 2'-hydroxy-5'-nonylacetophenone oxime. The method was successfully applied to quantify 5-dodecylsalicylaldoxime and 2'-hydroxy-5'-nonylacetophenone oxime in samples of commercial extractants over the concentration range 0.05–2.45 and 0.07–0.82 mg/L, respectively, with detection limits of 0.034 and 0.019 mg/L, respectively.


ABSTRACT Much attention has been centered on the use of emerging technologies in higher education, including flipped classes. However, widespread admiration for and adoption of these innovations seems to be occurring at a much faster pace than the assessment and evaluation of them. Questions about student performance in and perception of flipped classes remain unanswered, so more research is needed. This study examines student perceptions of a partially flipped Introduction to American Politics course. In general, the results indicate that students preferred the partially flipped format, although (1) it is not clear that students would prefer a fully flipped course, and (2) some aspects of the flipped format worked better than others.


ABSTRACT Primary objective: People often misattribute stroke survivors' symptoms to other causes such as their personality, especially when the survivors are young. As a result, these stroke survivors experience feelings of resentment towards and from their acquaintances, and may struggle to retain employment. This study aimed to clarify how people's misattributions for stroke symptoms were affected by varying information about the stroke. Methods: Experiment 1 examined whether the stroke survivor's age (72, 32 or unstated) and the information about the person's stroke (no information, explicit stroke or implied stroke) influenced participants' causal attributions for the stroke survivor's four ambiguous symptoms, such as fatigue. Experiment 2 examined the effect of the rapidity (a week or a year) with which the symptoms appeared. Results: When the scenario explicitly referred to stroke, participants attributed the ambiguous symptoms more to stroke, whereas when it did not mention stroke, participants attributed these symptoms more to other factors. When stroke was merely implied by reference to unilateral paralysis, participants rated stroke the best explanation when the target person was 72 but not when he was 32. Experiment 2 showed that stating that the symptoms happened rapidly heightened attributions to stroke in the 72-year-old but not the 32-year-old. Conclusions: These findings show how different information about stroke survivors affect people's attributions for survivors' behaviour; this has important implications for accurate diagnosis and effective rehabilitation that targets these attributions.


The catalytic double-bond shift isomerization of α-olefins by dithio-β-diketonate palladium complexes Pd{CH3C(S)CHC(S)CH3}(PL1L2L3)X(1) and [Pd{CH3C(S)CHC(S)CH3}{Ph2PCH2CH2PPh2}]Y(2)(X = 1, Br; Y = halide, PF6, BPh4) is described. Catalysts are formed on activation of the complexes by a variety of alkylaluminium cocatalysts . Several of the catalysts are highly active for isomerization of oct-1-ene and but-1-ene, activities being higher than normally obtained for palladium systems. In contrast to the majority of palladium-based catalysts product distributions rapidly approached thermodynamic equilibrium, with a strong preference for trans products at each stage of the reaction. Products from the isomerization of oct-1-ene were analysed by g.l.c.-F.t.i.r . in conjunction with Kovats retention indices.


Objective To observe the repairing effect of marrow derived mesenchymal stem cells(MSCs) on hepatic fibrosis in rats,and provide a reliable theoretical basis for further clinical application of MSCs.Methods The MSCs of rats were isolated,purified and cultivated in vitro.The model of hepatic fibrosis induced by CCl4 was established.The rats were divided into three groups:normal control group,model group,MSCs transplantation group,6 each group.The MSCs were transplatated into the rats through tail vein in MSCs transplantation group.The repairing effect of MSCs on hepatic fibrosis was observed and the expression of α-SMA in liver tissue was detected by immunohistochemistry 30 d after transplantation.Results 93.27% MSCs were at G0/G1 phase,and the CD44 surface expression in the MSCs was positive.The hepatic pathological injury changes of rats in MSCs transplantation group were significantly reduced than that in model group 30 d after MSCs injection.The lobular structure and liver sinusoids were normal and hyperplasia of fibrous connective tissue was not obvious.The intensity of α-SMA staining in MSCs transplantation group was lower than that in model group.Conclusion MSCs have repairment on hepatic fibrosis in rats to a certain extent.


INTRODUCTION Fisheries biology was established as a discipline ofits own near the turn of the last century, when scientistS in Northern Europe and America began to ask . • I themselves seriously why fish stocks fl~ctuate and, more specifically, why exploited stocks become depleted. Was it tlie effect offishing or, as many argued, mainly the result of environmental fluctuations? . The Intemational Council for the Exploration ofthe Sea (ICES) was founded in 1902, mainly to address this question. Because the question was broad, the initial areas of emphasis of ICES scientists were also broad, e.g., the precise estimation of salinity (hence, the "Copenhagen standard"), the study of plankton distribution and other topics now generally considered to be part of marine and/or biological oceanographybut not necessarily of fisheries biology (Went 1972). The early attempt by Baranov to demonstrate that fisheries stocks react to fishing in a predictable fashion and that this reaction could be expressed in. mathematical terms was not widely accepted, perhapsbecauseit was published. too early and in Russian (Baranov 1918). In the 1930s, the problems were reformulated by Russell (1931), who identified the "overfishing problem" through bold reductions, i.e., byneglecting the effects on exploited fish stocks of factors other than growth and mortality (fishing and natural). Russell's concept was subsequently refined by M. Graham, but with the unscheduled "closed season" of the Second World War, it awaited Beverton and Holt (1957) to formulate a quantitative description of the dynamics of exploited fish population which inspired fisheries biologists throughout the world. The Beverton and Holt model not only provided a description of the impact of fishing on stocks but also, like any good paradigm, suggested what fisheries scientists should do: they should put their emphasis on estimating fish growth and mortality, and on quantifying the relationship between the size of captured fish and the mesh sizes of the gear that caught them.


George Egerton's Keynotes (1893) is a seminal text of the New Woman movement at the fin de siècle and has garnered significant critical attention over the last four decades. Egerton went on to publish four more volumes of short fiction, with decreasing popularity, the last being Flies in Amber (1905). This article addresses the shortage of scholarship on Egerton's later writing by assessing the consistency with which she invokes moments of touch and object exchange as a means to radicalise motherhood in two popular and well-known early stories, "A Cross Line" and "The Spell of the White Elf" (Keynotes), and a less-known later story "Mammy" (Flies in Amber). Through tactile exchange, Egerton's female protagonists establish a maternal network that challenges patriarchal hypocrisy and preserves their New Womanhood. By understanding Egerton's valorisation of maternity as a "New Motherhood," this article challenges claims of essentialism and accusations of conventionality in Egerton's writing while reinstating the cultural value of her later publications.


With the deepening understanding of oral contraceptives(OC),other benefits of OC beyond the precise effects of contraception were realized.At present,OC were commonly used in many endocrine-related gynecological diseases,such as dysfunctional uterine bleeding among adolescence and perimenopausal period.The application of low dose combination OC in the treatment of primary dysmenorrheal showed better effects.And low dose OC could prevent the decrease of bone mineral density(BMD) during perimenopausal period and menopause,and reduce the risk of endometrial cancer and ovarian cancer.Although OC is generally safe,the evaluation of OC efficiency and risk should be enhanced in our future work to provide the optima roles of OC for human reproductive health.


A theoretical study which allows determination of the minimum number of vias for realizable multilayer channel routing under a topological model is presented. The theory is sufficiently general to solve a variety of problems under different technological constraints, e.g. VLSI multilayer switchbox and channel routing, through-hole printed circuit board (PCB) channels, and single-layer routing. Topological routing is concerned with wire intersection but not area, zero-width wires and zero-area vias being assumed. Unconstrained via minimization (UVM) is not constrained to a prerouted topology. This paper presents restrictive cases of UVM, finding most to be NP-hard, but the case resulting from constraints of traditional switchbox or channel routing to be solvable in O(kn/sup 2/), where k is the maximum number of pins of a net layer and n is the number of pins. The minimum number of vias for various switchbox and channel routing benchmarks are reported. >

Now that surgical methods can be used to treat successfully lesions of the aorta and major blood vessels, it is of the utmost importance that the radiologist develop technics for visualization of the larger vessels of the body. When opaque material is injected into an artery, it diffuses with the blood and is rapidly carried away from the point of injection. If a single roentgenogram is made at the time of injection, one may obtain visualization of the opaque material, though usually in a rather limited area of the vessel. If one uses a device for rapidly changing cassettes, a more extended view is obtained, showing the opaque material filling the vessels more peripherally. This method is usually quite adequate if one is dealing with the aorta or its iliac branches, but in investigation of the arteries of the leg, even a 14 × 17-inch film is not large enough to cover all the area desired. It was thought that the problem might be solved by a single exposure, using a 14 × 36-inch cassette, but while the bon...


In this paper, we consider a standard model of many-to-one matching markets. First, we study the relation between strategy-proofness and unanimity under a certain requirement and we prove these two properties become equivalent. Second, we illustrate that this result has an immediate impact on the relation between strategy-proofness and Maskin monotonicity. Finally, we determine a close connexion between strategy-proofness and implementation literature. We provide under certain minimal requirements the foundation for reasoning the equivalence among dominant strategy implementation, standard Nash implementation, and partially honest Nash implementation.

 Nutritional status is related to the prognosis and the length of hospitalization of individuals with heart failure. The effects of thyroid dysfunction in patients with pre-existing heart failure and nutritional status have not been adequately studied.

 This study aims to assess how nutritional status affects thyroid disease in patients with heart failure.

 We performed a retrospective study and analysis of medical records of 1056 patients admitted to the cardiology department of our University Clinical Hospital between September 2017 and September 2020 due to acute heart failure (HF) (ICD10: I50). We analyzed all the patients who met the inclusion criteria (diagnosis of HF, age ≥18 years old). A final group of 1056 patients' medical records was analyzed. The analysis included data such as age, gender, patients' body mass index (BMI), and laboratory results such as total data on past and comorbid disease units and assessment of the nutritional status of the patient via the NRS-2002. Our study was approved by the independent Bioethics Committee of the Wroclaw Medical University (decision no. KB–590/2020). Statistical analysis was performed using Statistica 13.1 (StatSoft, Inc., Tulsa, OK, USA). The results were considered statistically significant at p<0.05

 A total of 1056 individuals were included in the analysis. It included more men than women (66,7%) Due to a lack of data for some parameters, those numbers are smaller and are provided for each variable. More than 76% of participants were overweight or obese. 4.3% of patients were in risk of malnutrition. Thyroid disease registered in 15.1% of patients (Hyperthyroidism – 5.3% and Hypothyroidism 9.8%)
 Based on BMI, four groups were distinguished: <18.5, 18.5–24.9, 25.0–29.9, and ≥30 The occurrence of Hyperthyroidism was more frequently observed in the group of overweight patients (p=0,02) (table 1).
 Based on NRS2002, two groups were distinguished: <3 and ≥3. In the group with risk of malnutrition (NRS ≥3) patients had a mean statistically significant higher FT4 (<0.001) than the group with no risk of malnutrition (NRS <3) ( x̅ : 2,02 ng/dl vs x̅ : 1.35 ng/dl, p<0.001). Additionally, lower scores of FT3 were observed in the group NRS ≥3 (x̅ : 1.91 ng/dl, p<0.001) (table2).

 This study shows that patients with thyroid disease and heart failure were often overweight and obese. The risk of malnutrition status correlates with a lower result of FT3 and the highest FT4. Undoubtedly, those phenomena require further research.


Maternal and child health (MCH) and family planning (FP) services have increased in Lucknow city, but they are underutilized. A survey was conducted in Lucknow city with the following objectives: 1) to find out the extent of knowledge and utilization of MCH and FP services, 2) to study the degree of satisfaction among the users of Government-provided MCH and FP services, 3) to assess the factors affecting overall performance of Maternity Homes established in Lucknow city under the India Population Project. The design of the study and the sampling method used are described. Findings of the study include: 1) Demographic profile of an area does not affect overall performance of an MCH and FP service unit, but certain social characteristics (i.e. high numbers of Muslims, widespread illiteracy, intercity mobility) are more predominant in the area of the poorest performing Maternity Home. 2) Extent of knowledge of the service has no relationship with the overall performance of the service unit, but widespread knowledge of child immunization in a unit's area is a prerequisite for better overall performance. 3) Overall performance is enhanced by a preference for institutional delivery and a low rate of FP postacceptance complications in a unit's area. 4) Apprehension of rude hospital staff and low consciousness of the utility of services provided contribute to nonuse of Government-provided MCH services. 5) Lack of reliance on present methods and desire for more children are important reasons for nonuse of FP methods by eligible couples.


This paper explores dynamic processes of (re)negotiation of boundaries of and in China's Belt and Road Initiative. It identifies ambiguous temporal and spatial boundaries which create space for ongoing political and ideological contestation over the shape of the Belt and Road Initiative. The paper suggests that lack of clear geographical scope leaves open multiple futures for China's global relations under the initiative. Chinese imaginaries hint at a world of transnational networks of political economy but one still structured by nation states and inter-governmental regional institutions at a time when the intertwining of the political and the economic is a feature of shifting configurations of global political economy.


Let A be a dense Frechet *-subalgebra of a C*-algebra B. (We do not require Frechet algebras to be m-convex.) Let G be a Lie group, not necessarily connected, which acts on both A and B by *-automorphisms, and let σ be a sub-polynomial function from G to the nonnegative real numbers. If σ and the action of G on A satisfy certain simple properties, we define a dense Frechet *-subalgebra G ⋊σ A of the crossed product L1 (G, B). Our algebra consists of differentiable A-valued functions on G, rapidly vanishing in σ. We give conditions on σ and the action of G on A which imply the m-convexity of the dense subalgebra G ⋊σ A. A locally convex algebra is said to be m-convex if there is a family of submultiplicative seminorms for the topology of the algebra. The property of m-convexity is important for a Frechet algebra, and is useful in modern operator theory. If G acts as a transformation group on a locally compact space M, we develop a class of dense subalgebras for the crossed product L1 (G, C0 (M)), where C0 (M) denotes the continuous functions on M vanishing at infinity with the sup norm topology. We define Schwartz functions S (M) on M, which are differentiable with respect to some group action on M, and are rapidly vanishing with respect to some scale on M. We then form a dense Frechet *-subalgebra G ⋊σ S (M) of rapidly vanishing, G-differentiable functions from G to S (M). If the reciprocal of σ is in Lp (G) for some p, we prove that our group algebras Sσ (G) are nuclear Frechet spaces, and that G ⋊σ A is the projective completion .


The study area,the Mapao spring,is located in southwest of the Jinzhong basin,Shangxi Province.The Mapao spring catchment has an area of 212.06km2.Annual air temperature and precipitation in the study area average in 11.11℃ and 444.44mm and the elevation ranges from 1 100mto 1 900m,decreasing from west to east and from north to south.The strata exposed in the study area are primarily carbonate rocks(limestone and dolomite)of the Cambrian-Ordovician system.By means of comparison dissolution experiment under different vegetation conditions,testing analysis on the contents of soil organic carbon and soil inorganic carbon,and field measurement for the concentration of soil CO2and moisture content,the features of the dissolution rate and its impact factors in semiarid conditions in north China are revealed as follows.(1)The tablets dissolution rate,obvious different under different vegetation conditions,is the largest in forest land with the value of 0.551 1mg/(cm2·a),which is 2.13 times,2.16 times higher than that under shrub conditions and meadow land respectively.This result indicates that carbonate dissolution rate has an increasing tendency along with the positive succession of vegetation.(2)The tablets dissolution rate is mainly affected by soil organic carbon,soil inorganic carbon,soil moisture,but slightly affected by the soil CO2concentration.The soil organic carbon content and soil moisture is positive related with the tablets dissolution rate,the soil inorganic carbon content is negatively related with the tablets dissolution rate.So,high levels of inorganic carbon can lead to the weight of some tablets increase instead of decrease after a year's corrosion,which results in the tablets dissolution rate becomes slower.(3)The karst carbon sink intensity,i.e.1.815tCO2/(km2·a),calculated in light of the average dissolution rate in forest land and shrub land as well as grassland is smaller in comparison with the former figure,i.e.8.69t CO2/(km2·a),calculated in accordance with hydrochemistry-runoff method.This means that the amount of karst carbon sink being calculated by means of dissolution method is likely to be smaller than the actuality.


In the midst of the current pandemic, online learning is the main choice in the world of education. However, there was a wide range of student responses to the learning process. Furthermore, it is known that the perception of students towards learning submitted by influential lecturers to generate interest in learning students in understanding the materials provided. Therefore, the purpose of this study is to obtain concrete information about: 1) how students perceive the competence of lecturers in applying online learning; 2) how to motivate students to excel during online learning; and 3) is there any influence of student perception on the competence of lecturers with the motivation of student achievement. This research uses a combination research design and its data collection method, namely survey by providing questionnaire questionnaire link with googleform. The subjects of the study were 274 students of the even semester of the academic year 2019/2020 at Bina Bangsa University who responded to the poll. The conclusion is that the perception of students is very diverse towards the competence of lecturers in applying online learning, as well as the motivation of student achievement. Although the percentage of incline is positive, not a few have responded negatively. Furthermore, it is known that there is a significant and moderate influence between the perception of students towards the competence of lecturers and the motivation of student achievement. In other words, if the student's perception of lecturer's competence increases, it will be accompanied by increased motivation for student achievement.


MMA is polymerized anionically in THF at −70 o C in the presence of Li + , Na + , K + , Cs + , and cryptated K + cations and the reaction is terminated by ClSiMe 3 . The 13 C NMR results are consistent with the following assumptions: 1) transition-state monomer approach to the living end is s-cis for Li + and Na + (leading to Z chain ends) due to coordination with the counterion and s-trans for Cs + and cryptated K + (leading to E chain ends) due to steric reasons; 2) tacticity is determined by the E/Z stereoisomerism of the chain end and possibly also by the stereochemistry of the preceding diad; 3) with increasing radius of the counterion, addition of monomer to E isomers results in an increasing fraction of racemic diads, while the Z isomers give a decreasing amount of racemic diads


The rotational state of Europa is only rather poorly constrained at present. It is known to rotate about an axis that is nearly perpendicular to the orbit plane, at a rate that is nearly constant and approximates the mean orbital rate. Small departures from a constant rotation rate and oscillations of the rotation axis both lead to stresses that may influence the location and orientation of surface tectonic features. However, at present geological evidence for either of these processes is disputed. We describe a variety of issues that future geodetic observations will likely resolve, including variations in the rate and direction of rotation, on a wide range of timescales. Since the external perturbations causing these changes are generally well known, observations of the amplitude and phase of the responses will provide important information about the internal structure of Europa. We focus on three aspects of the rotational dynamics: obliquity, forced librations, and possible small departures from a synchronous rotation rate. Europa's obliquity should be nonzero, while the rotation rate is likely to be synchronous unless lateral shell thickness variations occur. The tectonic consequences of a nonzero obliquity and true polar wander have yet to be thoroughly investigated.

Objective: To assess the association of plasma plasminogen activator inhibitor 1 (PAI-1) and tissue plasminogen activator (tPA) antigen concentrations and related cardiac risk factors in patients with acute coronary syndrome and their first degree relatives. Material and Methods: Thirty-eight patients with acute coronary syndrome (33 men and 5 women, mean age 58 ± 9 years) and their 20 first-degree relatives (16 men and 4 women, mean age 52±7 years) were included in the study. The mean period of time that elapsed between the last episode of chest pain and blood sampling from the patients was 3.5 ± 1 hours. Blood samples were collected from patients and their relatives simultaneously. All patients underwent coronary angiography. Thirty patients had multivessel disease. Results: The two groups did not differ in gender (p= 0.218). Patients were older (p< 0.05) and smoked more (p< 0.001) than their relatives. There were no significant differences in plasma tPA and PAI-1 antigen concentrations between patients and their relatives (10.4 ± 5.6 vs 11.4 ± 4.6 ng/ml, p= 0.452 and 68.9 ± 23.5 vs 68.8 ± 17.3 ng/ml, p= 0.583), and, between patients with multivessel disease and their relatives (11 ± 6 vs 11.4 ± 4.6 ng/ml, p= 0.168 and 70.6 ± 24.1 vs 68.8 ± 17.3 ng/ml, p= 0.996, respectively). In the first degree relatives group there was a moderate, inverse correlation between PAI-1 antigen and HDL cholesterol (rho= -0.47; p< 0.05). In the patient group, LDL cholesterol and triglycerides significantly correlated with plasma PAI-1 antigen concentrations (t= 2.084, p= 0.045 and t= 2.365, p= 0.024) with strong partial correlation coefficients (β= 0.983 and β= 1.13 respectively). Conclusion: The insignificance of the difference between patients with acute coronary syndrome and their healthy first-degree relatives in plasma levels of tPA and PAI-1 antigen and the poor relation of these markers with cardiac risk factors may be attributed to the multifactorial mediation of the release and functioning of tPA and PAI-1.


manual (liquefied) and computer (washed) analysis of strict sperm morphology. Intra-and inter-computer analyses using this method reached satisfactory levels of agreement. There is still high inter-laboratory variability for the manual method. Introduction The assessment of sperm morphology, an integral component of the basic semen evaluation, has been demonstrated to aid the clinician in the management of male infertility (Oehninger and Kruger, 1995). It is clear that the evaluation of a single sperm feature or function may not provide enough power for

Abstract : This paper reports on a 12-month randomized controlled trial that compared supported employment plus Cognitive Symptom Management and Rehabilitation Therapy (SE-Cog) to enhanced supported employment (ESE) for OEF/OIF veterans with mild to moderate traumatic brain injury (TBI) who are unemployed and want to return to work. CogSMART is a manualized, 12-week compensatory cognitive training intervention designed to provide the following: (1) psychoeducation; (2) strategies to address sleep problems, fatigue, headaches, and stress; and (3) strategies to improve prospective memory, attention, learning/memory, and executive functioning. Assessments of cognition, post-concussive symptoms, psychiatric symptoms, functional skills, and quality of life will be administered at baseline, and at 3, 6, and 12 months following study enrollment. Work outcomes (i.e., weeks and hours worked; wages earned) will be measured weekly during the 12-month study. Repeated measures ANOVA using baseline and three-month scores showed that, compared with the ESE group, SE-Cog participants reported more improvement in post-concussive symptoms (F=36.6, df=1,5, p=.002); there also were trends toward improvement in verbal fluency and quality of life. Forty-four percent of the SE-Cog participants and none of the ESE participants have obtained work thus far. These results suggest that CogSMART, in the context of supported employment, may improve post-concussive symptoms, cognitive performance, and work outcomes.


Health impacts of air pollutants, especially fine particles (PM2.5) and NO2, have been documented worldwide by epidemiological studies. Most of the existing studies utilised the concentration measured at the ambient stations to represent the pollutant inhaled by individuals. However, these measurement data are in fact not able to reflect the real concentration a person is exposed to since people spend most of their time indoors and are also affected by indoor sources. The authors developed a probabilistic methodology framework to simulate the lifelong exposure to PM2.5 and NO2 simultaneously for population subgroups that are characterised by a number of indicators such as age, gender and socio-economic status. The methodology framework incorporates the methods for simulating the long-term outdoor air quality, the pollutant concentration in different micro-environments, the time-activity pattern of population subgroups and the retrospective life course trajectories. This approach was applied to the population in the EU27 countries plus Norway and Switzerland and validated with the measurement data from European multi-centre study, EXPOLIS. Results show that the annual average exposure to PM2.5 and NO2 at European level kept increasing from the 1950s to a peak between the 1980s and the 1990s and showed a decrease until 2015 due to the implementation of a series of directives. It is also revealed that the exposure to both pollutants was affected by geographical location, gender and income level. The average annual exposure over the lifetime of an 80-year-old European to PM2.5 and NO2 amounted to 23.86 (95% CI: 2.95–81.86) and 13.49 (95% CI: 1.36–43.84) µg/m3. The application of this methodology provides valuable insights and novel tools for exposure modelling and environmental studies.


Nonadiabatic dynamics around an avoid crossing or a conical intersection play a crucial role in the photoinduced processes of most polyatomic molecules. The present work shows that the topological phase in conical intersection makes the behavior of pump-probe high-order harmonic spectroscopy different from the case of avoid crossing. The coherence built up when the system crosses the avoid crossing will lead to the oscillatory behavior of the spectrum, while the geometric phase erodes these oscillations in the case of conical intersection. Additionally, the dynamical blueshift and the splitting of time-resolved spectrum allow capturing the snapshot dynamics with sub-femtosecond resolution.


The aim of this paper is to examine the ways that emotions are communicated in conditionals employed in Greek political speeches. In particular, it is suggested that conditional constructions along with their conjunctions, such as the markers an (if) and ean (if) carry a particular emotional load in the Greek political context. Based on Athanasiadou and Dirven' s (1996) typology of if -clauses, a sample of conditionals was analysed. The findings show a prevalence of the pragmatic conditional type; a conditional type with an intense conversational nature which carries specific illocutionary acts, such as warning, request or advice, accompanied most of the time by negative emotions, such as anger, dislike, contempt, irritation, alarm, intimidation and pride . In other words, the choice of the pragmatic type in combination with certain conjunctions is associated with specific negative emotions which consequently generate reactions such as sarcasm, irony, scaremongering, cajolery and fake politeness. Overall, the paper discusses devices through which conditional constructions reflect emotions.


PHOTOPERIODIC control of testicular growth is apparently quite general among Temperate Zone species of birds (Farner, 1959, 1964a; Wolfson, 1959; Hamner, 1966). Yet detailed information on the course of testicular growth induced by stimulatory daily photoperiods of constant duration is limited to only a few. Although testicular growth is known to be photoperiodically controlled in Zonotrichia querula (Rowan, 1938; King and Farner, 1963), the relationship between testicular weight and time in photosensitive, photostimulated birds has neither been expressed nor quantified. The present study was undertaken to determine the temporal course and rate of testicular growth in Z. querula exposed to long (20-hour) daily photoperiods.


Kazumasa Iida Nagoya University, Department of Crystalline Materials Science, Graduate School of Engineering, Nagoya 464-8603, Japan E-mail: firstname.lastname@example.com. ac.jp This is a viewpoint on the fast track communication by Weiss et al (2015 Supercond. Sci. Technol. 28 112001). Superconducting magnets can generate an enormous large magnetic field far beyond a field produced by a conventional permanent magnet. Such a high magnetic field has been utilized in various applications, e.g., magnetic resonance imaging (MRI) for medical diagnosis and particle accelerators for high energy physics. Among the superconducting magnets, bulk (LRE)-Ba-Cu-O (LRE: light rare-Earth-elements and yttrium), and MgB2 samples are well-known quasisuperconducting magnets [1, 2]. The ability to trap a field is proportional to the product of the sample critical current density (Jc) and the size of the loop defined by the supercurrent. Hence, enhancement of Jc coupled with the fabrication of larger, weak-link-free grains, is a general processing aim for improving the field trapping capability of bulk superconductors. Recent developments of bulk quasimagnets are significant, and have led to a record trapped field of 17.6 T for Gd-BaCu-O at low temperatures [3]. Furthermore, portable MRI using (LRE)-Ba-Cu-O bulk superconductors have been developed [4]. However, highly textured grains are necessary for generating high-trapped magnetic fields due to extremely short coherence lengths and unconventional symmetry of the superconducting order parameter (OP). The additional problem with cuprate-bulk-magnets is an inherently weak mechanical strength, which restricts the capability of trapped magnetic field for those systems [5]. MgB2, showing the highest Tc among the BCS superconductors, can overcome the aforementioned two problems: (i) biaxial-textured grains are not necessary owing to a relatively long coherence length. Indeed, randomly oriented sintered bulk MgB2 shows a high-trapped magnetic field of 3 T at 20 K [6]. It should be noted that trapped field is increased in accordance with the increase of Jc by lowering the temperature. Hence, further decreasing the temperature yields a significant increase in the trapped magnetic fields. (ii) The mechanical strength of MgB2 bulk is much higher than that of (LRE)-Ba-Cu-O. An average fracture strength of MgB2 at 77 K is almost 2∼4 times higher than that of (LRE)-Ba-Cu-O [7]. However, the upper critical field (Hc2) of MgB2 is relatively small, typically less than 10 T at 20 K. The addition of carbon to the system improves the Hc2 [8], however, it is still a low value in comparison with the recently discovered Febased superconductors (FBS) and cuprates. The recent report of a high global Jc in randomly oriented K-doped BaFe2As2 (Ba-122) grains by Weiss et al was rather surprising [9], since this material class shows a short coherence length, similar to cuprates, and an unconventional OP. Hence, their findings have stimulated the research of pnictide wires and tapes. At present, in-field Jc ( H 28T 0 m = ) at 4.2 K reached over 3 × 10 4 A cm[10], which is almost the practical level for high-field magnet applications. Now, Weiss et al have demonstrated a possible trapped field magnet application using pnictide bulk samples. As stated in their fast track communication, the trapped field ability of K-doped Ba-122 bulk samples is potentially competitive with that of MgB2 and (LRE)-Ba-Cu-O for several reasons. Firstly, the Hc2 value of pnictides is far


A flat-panel and resistor-type photomultiplier tube (FRP) system, which is a two-dimensional positionsensitive neutron detector, has been developed. The FRP detector consists of a scintillator, a multi-anode photomultiplier tube (MA-PMT), a resistor network board, and an FRP amplifier and a readout circuit which is similar to that for the old resistor type photomultiplier tube (RPMT) system. Therefore, the FRP system uses the same readout circuit of the RPMT system. Two types of FRP detector are available. One is the FRP4 detector, which consists of four MA-PMTs with a detection area of 10-cm square. The position resolution due to irradiation of neutron beam with approximately 0.5-mm diameter is 1.26 mm in the X axis and 1.61 mm in the Y axis. The other one is the FRP1, which consists of one MA-PMT with a detection area of 5-cm square. The position resolution due to irradiation of a neutron beam with approximately 0.5-mm diameter is 0.83 mm in the X axis and 0.89 mm in the Y axis. The FRP detector can be used for high position-resolution and transmission experiments of a compact neutron source.

Abstract: An experiment was conducted to study the effects of dietary supplementation of 1,2-diacylglycerol (1,2-DAG) and 1,3-diacylglycerol (1,3-DAG) as emulsifier in a corn–soybean-meal-based diet on growth performance, nutrient digestibility, and blood characteristics in growing pigs. A total of 75 cross-bred [(Landrace × Yorkshire) × Duroc] growing pigs with an initial body weight (BW) of 24.27 ± 1.58 kg were used in a 6 wk trial. Pigs were randomly allocated into one of three treatments according to their sex and BW (five replicates with two gilts and three barrows per replication pen). Treatments were as follows: (1) CON, basal diet; (2) TRT1, CON + 0.1% 1,2-DAG; and (3) TRT2, CON + 0.1% 1,3-DAG. The DAG diets trended to increase BW, average daily gain (ADG), and average daily feed intake (P < 0.10) compared with CON diet in growing pigs. Pigs fed with DAG diets had higher (P < 0.05) digestibility of dry matter and nitrogen compared with the CON diet. Dietary supplementation with 1,3-DAG diet increased (P < 0.05) high-density lipoprotein cholesterol concentration, and triglycerides concentration was decreased (P < 0.05) in the 1,2-DAG and 1,3-DAG diets. In conclusion, dietary DAG supplementation positively affected ADG, nutrient digestibility, and blood profiles in growing pigs, especially 1,3-DAG.


Taking a micro-level approach, this study questions whether the positive impacts of tourism often claimed at the macro level do indeed trickle down to the grassroots level to lift local people out of poverty. A case study of the local community in Barabarani village, Mto wa Mbu, Arusha, on Tanzania's popular northern tourist circuit, compares the perspectives of local residents and key decision-makers in the community. The extent to which tourism development has affected seven signifiers of poverty alleviation are examined: accessibility improvement (transport and communication), prices of goods and services, entrepreneurial training, income-generating projects, employment opportunities, general quality of life and household income. Most of the local community felt tourism development is having a positive impact and contributing to poverty alleviation, especially in terms of improving local facilities. However, there are variations, with household distance from the main road through the community being a determining factor.
