In this paper we address the problem of queries expansion and its perso nalization which consists of enriching user queries with additional information to maximiz e her satisfaction according to, e.g., her interests and her social ecosystem. While focusing on tagging systems, the proposed approach considers (i) the semantic similarity betw een ags composing a query, (ii) a social proximity between the query and the user profile for pe rsonalized expansion, and (iii) on the fly, a strategy for expanding user queries. The proposed approach has been evaluated using a large dataset crawled from del.icio.us and compared to the closest related work and the results show a clear superiority of our approach and prom ising results.

Advection transport effects by wind field is a very important macroscopically dynamical process for weather systems in real atmosphere.Cloud hydrometeor advections by three-dimensional velocity vector are closely related to evolution of precipitable cloud system and connect the macroscopically dynamical process with the temporal and spatial variations of cloud hydrometeors.The advection transport of cloud hydrometeors may increase or decrease the contents of cloud hydrometeors and change their spatial distributions so that the development of precipitable cloud system may be prompted or broken up.The purpose of this paper is to investigate the influence of macroscopically dynamical process on cloud microphysical process by changing the cloud hydrometeor advection transports in the numeric simulation of a heavy-rainfall event occurring in North China during 00:00 UTC 12 - 00:00 UTC 13 August 2004. Combining the NCEP/NCAR real analysis data and routine observations of surface level and sounding,the ARPS model is employed to carry out simulations of the heavy rainfall event,including one controlling experiment and three numerical experiments in which the horizontal,vertical and total three-dimensional advection transports of cloud hydrometeors were excluded,respectively.The result showed that the simulated specific humidity was little influenced by the cloud hydrometeor advection transports.The three-dimensional advection transports of cloud hydrometeors was propitious to enrich the mixing ratios of snow and graupel,while the contents of cloud water,rain water and ice were held back.The horizontal advection transports of cloud hydrometeors contributed to the mixing ratios of ice and snow,and diminished the contents of cloud water and rain water.The vertical advection transports of cloud hydrometeors improved the mixing ratios of rain water,snow and graupel and at the same time,worsened the content of ice.The analysis of three-dimensional advection transport effects showed that the influence of three-dimensional advection transports of cloud hydrometeors on precipitable cloud system was realized via adjusting the source or sink of cloud hydrometeors produced by cloud microphysical processes and the sedimentation of precipitable hydrometeors(rain water,snow and graupel),and then changing the vertical spatial structures of cloud hydrometeors.In addition,the contribution of the advection transport of snow to itself was also important.


To observe the effect of neuritin on promoting fracture healing in SD-rats,and to explore new drug intervention for nonunion and bone defects in clinical treatment.96 healthy SD rats were randomly divided into experimental and control groups,72 cases for experimental group and 24 cases for control group.All animals were manufactured to fracture model through braking right middle femur by intramedullary retrograde Kirschner wire fixation.Control group had no special handling.Experimental groups,namely group A,group B and group C,were respectively given daily gavage 0.1 μm/L,0.05 μm/L and 0.025 μm/L neuritin treatment,and were killed after 1-week,2-week and 4-week respectively,and were analyzed through taking X-ray,surveying callus volume,and manufacturing pathological section.Specimens observation and X-ray showed that,fracture healing callus ossification rate of the experimental group was significantly faster than the control group(P0.05);group A was significantly faster than group C(P0.05);Callus volume measurement showed that,callus volume were significant different and significantly larger than the control group(P0.05);group A was significantly larger than group C(P0.05);HE staining showed that,the experimental group in each group appears early granulation tissue fibrosis,the number of cartilage cells and bone cells of all the experimental groups at the same time points was clearly higher than the control group(P0.05).Local injection of neuritin could increase the callus content and the speed of callus ossification.


TO THE EDITOR: We read with interest Shepperd and colleagues' (1) study of hospital at home (HAH) for admission avoidance. We congratulate the authors for a multisite deployment of a complex care model. The trial unfortunately failed to show superiority for its primary outcome (that is, living at home at 6 months) and several secondary outcomes. Here, we highlight 3 issues that may explain their null findings. First, there is some variation in the definition of HAH care. However, it is generally defined as the provision of hospitallevel care in a patient's home as a substitute for care that would otherwise be provided in a traditional hospital (2). In Shepperd and colleagues' study, the services did not seem to meet that definition. For example, all sites held rounds only 5 days per week; 8 of 9 sites could not provide a 24-hour-per-day, 7-dayper-week response in the home; 2 of 9 sites could not administer intravenous antibiotics; and an unspecified number of sites could not deliver oxygen. The number of visits a patient received per day was not reported. The authors do not make comparisons with prior literature to explain their findings, which differ from previous research with respect to death, readmission, and other measures (3–5). Second, although the authors should be congratulated for proposing a robust patient-level randomization schema, this schema does not seem to have remained intact. Thirty-seven participants originally allocated to home were escalated to a hospital before initiation of care at home because of decline, whereas 22% of those assigned to a hospital were instead admitted to home "because of participant preference or a high rate of hospital bed occupancy." Finally, the clinical presentations that were cared for, coupled with a high mortality rate, make understanding the patient phenotype challenging. The presenting problem for more than 37% of admissions was acute functional deterioration; for over 21%, it was fall. Only 2.3% and 5.2% had a presenting problem of heart failure and respiratory conditions, respectively. This deviates substantially from the literature (3–5) and further raises the question of whether the intervention was HAH or whether the study was a comparison of inpatient care versus outpatient comprehensive geriatric assessment, augmented home-based primary care, or home-based palliative care. Shepperd and colleagues' study raises important issues for the field in how to define and measure the effect of HAH interventions. We propose that an international body formulate a consensus definition of HAH to helpmove the field forward.


Introduction. Academic achievement is reflected in marks (points) achieved in the disciplines studied and it assumes that the student has acquired the required set of skills and knowledge, which he or she can use while performing educational and professional tasks after learning a particular discipline or a group of disciplines. This means that the concept of "academic achievement" represents measuring the student's ability to comprehend academic programmes in the class or independently. The aims of the present research were the following: to determine the ability of students to be active users of educational databases and their elements, which are considered to be effective especially in this type of educational activity; to identify the opportunities to improve academic achievement and the quality of academic curriculum implementation (in accordance with the necessary content) through digital educational content. Methodology and research methods . The present research is based on the field survey methodology. Empirical data were collected through questionnaires and face-to-face interviews. The validity of the collected material was verified through the method of mathematical statistics. Results and scientific novelty . It is known that information technology today is one of the most important factors, which can have a powerful impact on the quality of the education system in universities. The research conducted at the Northern Border University (Arar, Saudi Arabia) investigated the following questions: how the databases available at the Saudi Digital Library assist students of various specialties (faculties) in their studies; what the real contribution of the databases to the training of future professionals is; how learners define their goals and needs by using these databases. The processed questionnaire and interview results demonstrated that for most students e-learning content is not a tool to improve academic performance. The students' satisfaction with the offered e-learning content was very low. Meanwhile, the students noted that they needed accessible and quality digitised educational information. However, they lack the information competency to find, store and apply information in its various forms. This competency is not limited only to the skills to work with the computer (all young people possess this skill today) - it includes the skills to systematise and structure the received information; critical attitudes towards it; ability to summarise and draw conclusions. It is also important to have easy and user-friendly database tools. Thus, it is necessary to provide further guidance for learners on effective work with digital databases; to develop students' research skills; to carry out specialised workshops in order to motivate students to use digital educational resources. Practical significance . The present research materials can be useful for specialists developing university digital databases based on curricula mastered by students.


In the control system of low-pressure casting, traditional PID control algorithm has well static characteristics, no steady-state error; but its dynamic performance was poor, and prone to overshoot. To solve this problem, a fuzzy PID controller with three control parameters of KP, KI and KD was designed to adjust online, and realized by PLC controller.


We simulate magnetorheological fluids (MRF) using open source LIGGGHTS soft sphere discrete element method code, extended by us to include a mutual dipole magnetic model. Our simulations take advantage of the many pair forces available in the LIGGGHTS framework, including SJKR cohesion, friction, and rolling resistance. In addition, we have included an uncoupled, Couette flow background carrier fluid. The simulated particles in this work are polydisperse, with distributions made to match the distributions used to produce magnetorheological fluids in literature, increasing the fidelity of the simulations. Using the accurate particle size distributions, high heritage contact models, and an uncoupled fluid model, we are able to match experimental MRF yield stress results more closely than with monodisperse simulations.


Pulsars inside binary systems can accrete matter that arrives up to the pulsar surface provided that its period is long enough. During the accretion process, matter has to be accelerated to the rotational velocity of the pulsar magnetosphere at the distance where the balance between the pressure of matter and the magnetic field is achieved. At this distance, a very turbulent and magnetized region is formed in which hadrons can be accelerated to relativistic energies. These hadrons can interact with the very strong radiation field coming from the hot polar cap on the neutron star surface created by the in-falling matter. We calculate the neutrino event rates produced in a ${\mathrm{km}}^{2}$ detector that can be expected from accreting millisecond and classical x-ray pulsars at a typical distance within our own Galaxy.


Deep learning (DL) has recently been a core ingredient in modern computer vision tasks, triggering a wave of revolutions in various fields. The hyperspectral image (HSI) classification task is no exception. A wide range of DL-based methods have shone brilliantly in HSI classification. However, understanding how to better exploit spectral and spatial information regarding HSI is still an open area of enquiry. In this article, we propose a hybrid convolution and hybrid resolution network with double attention for HSI classification. First, densely connected 3D convolutional layers are employed to extract preliminary spatial–spectral features. Second, these coarse features are fed to the hybrid resolution module, which mines the features at multiple scales to obtain high-level semantic information and low-level local information. Finally, we introduce a novel attention mechanism for further feature adjustment and refinement. Extensive experiments are conducted to evaluate our model in a holistic manner. Compared to several popular methods, our approach yields promising results for four datasets.


In the present work, the generation and propagation of entropy noise was simulated applying a compressible three dimensional URANS CFD approach. To this end, a test rig, the so-called Entropy Wave Generator (EWG) was modeled. The EWG implies a non-reactive tube flow where entropy modes are induced to the air flow by a heating module. The generated temperature nonuniformities are accelerated in a convergent-divergent nozzle and excite entropy noise. Simulation results of pressure fluctuations and power spectra in the standard configuration as well as simulations of different operating points of the EWG are in very good agreement with measurements. Additionally, entropy noise was deduced for realistic gas turbine conditions with calculated sound pressure level above 160 dB, which evidences the relevance of entropy noise in gas turbines. The numerical investigation is completed by the analysis of the acoustic sources. For this purpose the acoustic sources caused by the acceleration of density inhomogeneities suggested by Dowling [1] were calculated. Thus, for the first time a method is introduced to locate the acoustic sources of entropy noise in the acceleration region.Copyright © 2008 by German Aerospace Center


Procedures were investigated for upgrading vanadium black cake of nominal 86% V/sub 2/O/sub 5/ grade. The objective of the research was to delineate and compare alternative methods for conventing the high-alkali black cake to a product of minimum 98% V/sub 2/O/sub 5/ grade. Procedures that were investigated included metathesis of black cake in natural, acid, and alkaline solutions of ammonium chloride to form ammonium vanadate, and dissolution of black cake in soda ash solution and subsequent precipitation of ammonium vanadate by addition of ammonium chloride to the soda ash leach liquor. The ammonium vanadate-type material made by the alternative procedures was decomposed to the oxide by heating at 450 deg C. The simplest procedure, metathesis in ammonium chloride solution, yielded 99% recovery of V/sub 2/O/sub 5/ in a product that contained about 4% total impurities, principally sodium, potassium, molybdenum, and manganese. A modification of this procedure that involved acidifying the solution to a pH of about 2 resulted in 98% recovery in a product that contained about 2% total impurities. Another modification, comprising addition of ammonia to the chloride solution, also yielded a product containing 2% total impurities, but the potassium content was higher and the molybdenum content lower thanmore » that obtained by treatment with acid solution. Vanadium recovery resulting from the use of ammoniacal solution exceeded 99%. The soda ash dissolution method corresponding to industrial practice for preparation of pure vanadium oxide resulted in over 99% vanadium recovery at 99+% V/sub 2/O/sub 5/ grade. Reagent requirements ranged from 2.5 pounds ammonium chloride per pound of black cake by metathesis in acid solution to 0.5 pound aminonium chioride and 0.2 pound ammonia when reacting in ammoniacal solution. The latter method, although economical with regard to reagents, required use of a close reaction vessel. The soda ash dissolution procedure was intermediate in reagent cost but embraced more process steps than the other procedures. (auth)« less


Five satellite top-of-atmosphere (TOA) albedo products over land were evaluated in this study including global products from the Advanced Very High Resolution Radiometer (AVHRR) (TAL-AVHRR), Moderate Resolution Imaging Spectroradiometer (MODIS) (TAL-MODIS), and Clouds and the Earth's Radiant Energy System (CERES); one regional product from the Climate Monitoring Satellite Application Facility (CM SAF); and one harmonized product termed Diagnosing Earth's Energy Pathways in the Climate system (DEEP-C). Results showed that overall, there is good consistency among these five products, particularly after the year 2000. The differences among these products in the high-latitude regions were relatively larger. The percentage differences among TAL-AVHRR, TAL-MODIS, and CERES were generally less than 20%, while the differences between TAL-AVHRR and DEEP-C before 2000 were much larger. Except for the obvious decrease in the differences after 2000, the differences did not show significant changes over time, but varied among different regions. The differences between TAL-AVHRR and the other products were relatively large in the high-latitude regions of North America, Asia, and the Maritime Continent, while the differences between DEEP-C and CM SAF in Europe and Africa were smaller. Interannual variability was consistent between products after 2000, before which the differences among the three products were much larger.


There exists a large gap in the soft ground settlement between theory prediction and the practice,so it is difficult to meet the design requirements and is not conducive to guide the construction.Combination of existing theoretical prediction methods and field observation information is helpful to control the engineering construction.With the combination of genetic algorithm and BP optimization method to train the network,weights of BP neural network can be optimized;with Gong Paz curve to decompose the settlement timing,network was trained by offset of settlement trend line.Good application results were achieved in predicting soft ground settlement by using this method.


Cut vertices, a generalization of matrix elements of composite operators, are introduced. Their renormalization is discussed. The Bogalubov-Parasink-Hepp-Zimmermann method of renormalization of cut vertices allows one to obtain a generalization of the Wilson expansion where cut vertices multiplied by singular functions appear rather than local operators times singular functions. A Callan-Symanzik equation for the moments of the structure function in e/sup +/ + e/sup -/ ..-->.. hadron (p) + anything is derived. This equation is valid to all orders of perturbation theory in both gauge and nongauge theories. Expamples of renormalization through the two-loop level are given.

Introduction and purpose of the study. The article is devoted to theoretical substantiation of models of specially organized motor activity of students of different groups of specialties. The urgency of this problem is due to the fact that the decrease in motor activity of student youth, which is observed in the current conditions of intensification of education, causes the deterioration of health, decrease in physical fitness and working capacity of future specialists. The hypothesis of the study - the use of models of specially organized physical activity in the system of physical education of students of different groups of specialties, will allow to ensure the proper volume of their physical activity and will contribute to better training of future specialists for fulfilling their professional duties. The purpose of the study is to substantiate the models of motor activity of students of different groups of specialties in order to ensure the proper volume of motor activity and improve the quality of training of future specialists to perform their professional duties.

The article provides an overview of the areas of Russian Arabic Studies except linguistics. Since Eastern regional studies are inconceivable without knowledge of the language and culture of the regions under study, the analysis of studies in the modern Arab world is preceded by a review of key works that explained the specifics of the literature and philosophy of the Arab world. Thus, the first section examines key figures in the study of classical and modern literature of the Arab countries, the medieval history of this region. The second section is devoted to the philosophyof the Arab East. The largest third section is focused on the study of economic, social, and political processes in Arab countries in the XX century. It is indicated that Russian scientists, despite the forced domination of Marxist-Leninist dogmas in the social sciences, managed to create numerous scientific works that are among the distinguished Arabic Studies worldwide. The final section contains an analysis of contemporary studies of the Arab world in Russia. The article highlights key achievements of the scientific schools of Russian Arabic Studies providing information on more than two hundred monographs.

The aims of this research were to know the effect of CaCl  salinity to the growth, accumulation of prolin and tissue nitrogen content of 2 "orok-orok" (Crotalaria juncea L.), as well as to know the correlation between accumulation of the prolin with tissue nitrogen content. The outline of the research is that every plant, which is exposed to salinity, would accumulate prolin in order to make osmotic 2+ adjustment. Prolin consist of nitrogen (N). CaCl contains ion Ca ; it can effect the removal of N by plant, consisting the saline 2 condition of N removal by plant is blocked. The experiment arranged at a Completely Random Design with one factor i.e., CaCl 2 concentration in four levels: 0,0 M; 0,05 M; 0,10 M and 0,15 M respectively. The treatment was done in 35 days (the last of vegetative period). The growth parameters measured were shoots, root's length, wet weight, dry weight, root/shoot ratio, leaf wide total, stomata density, prolin content, and tissue nitrogen content. The data obtained were analyzed by Analysis of Varian and followed by DMRT with 5% confidence level. The result of the research indicated that the concentration of CaCl influenced in plant growth and prolin 2 accumulation. The higher CaCl concentration, the higher growth inhibition and prolin accumulation. Prolin accumulation has a negative 2 correlation to the growth and the tissue nitrogen content. Key words: Crotalaria juncea L., prolin, salinity.


I illuminate that in Maxwell S. Sucharov's article, and the phenomenology of complexity that it articulates, the complexity of the person and the person's experience of his complexity constitute inextricably interrelated elements of a larger existential-experiential whole. Accordingly, in his framework complexity must be experienced, felt or "lived" in order to be fully known and, by extension, meaningfully useful. I show that Sucharov's writing exemplifies his thesis of lived complexity in so far as it interweaves—to great rhetorical effect—explanatory complexity theory and its philosophical or transpersonal foundations, on one hand, with evocative and illustrative stories from his own personal life and professional work, on the other hand. Sucharov's article, the product of this weave, emerges as a metalogue that brings the reader's experience of Sucharov's holistic thesis alive on contemporaneously intellectual and emotional (and perhaps spiritual) levels. I offer various expository and critical remarks on Sucharov's thinking. In the end, I contend that Sucharov's phenomenology of complexity entails a method of knowing, or epistemology, that may represent its most important and lasting contribution to psychoanalysis. In it he implores psychoanalysts (and other clinicians) to stay close to their personal experiences of complexity, and thereby to the inherent irreducibility of their own and their patients' subjectivities, so that their thinking and clinical activities are less likely to fall prey to the myriad forms of hurtful reductionism to which we are all vulnerable.


Cloud users store millions of files on the cloud every day. Often times the files are simply replicated so that if one is lost a mirror can be fetched when required. Simple replication of data files is easier however it is more costly since more storage is required. Alternatively, cloud datacenters use coding techniques that code a file into parts; each of which can be stored at a different location and sometimes geographically distant locations. The biggest advantage of coding is that not all the parts are required to reconstruct the file in case one of more parts are lost. This is especially useful in presence of disk failures that frequently occur in datacenters. In this paper we present an analytical model of the reconstruction process with reference to delays incurred during the reconstruction process.


Sulfide derivatives are sulfur compounds mostly found in oil and its presence may cause serious consequences to the pipe in the withdrawal of oil, as well as its refining. For these reasons, its determination and removal are highly relevant to the oil industry. In this work, a graphite-epoxy composite electrode modified by nickel film was developed for the quantification of sulfide in oil industry samples. The composition of 65 % graphite was the one that originates better performance after characterization of electrodes by cyclic voltammetry and thermogravimetric analysis. A methodology was developed for electrodeposition films, and application studies of modified electrodes for monitoring the efficiency of H2S scavengers as a means of sulfide removal.

Malaria has been endemic in China for a long time. The presence of the ancient Chinese character "Nuk" (Malaria) among inscriptions on oracle-bone and bronzes of the Shang dynasty (about 16th century-11 th century B.C.) indicates that malaria was recognized as a disease entity in China more than 3, 000 years ago. However, albeit all the sufferings it had brought to the Chinese people, practically no attempt was made to contain it prior to the founding of the people's Republic. This paper is a brief report on the present status of malaria and its control in China.


Under uncontrolled image conditions, one of the greatest remaining research challenges in face recognition is to recognize faces across different poses. For multi-views face recognition problem either by means of difficult practical three-dimensional methods, either by means of a complex nonlinear transform algorithm. In order to overcome the poses problem, this paper analyzed the spatial change of different pose, regarded the faces with different pose space as a kind of approximate linear relationship by discretion of face pose space. As a consequence, a pose invariant face recognition method based on Orthogonal Procrustes analysis and sparse representation is proposed in this paper. Experimental results demonstrate that the presented algorithm possesses good robustness for the face variation of poses.


musical settings, the otherwise splendid Ariel had to recite, rather than sing, his songs. I was also disappointed by the far-less-than-poetic utterance of many of the lines of the play. For instance, Caliban, one of Shakespeare's most poetic characters, was played with total brutality and brilliant comic dexterity, but little poetry. Making use of a small hut with traveler curtains set up in the center of the vast stage, Director Robert Benedetti staged a lively "6commedia" version of The Comedy of Errors. Ever since Shake-

Quantitative and qualitative evaluations of ortho-images More recently, preliminary accuracy tests with real images were thus performed with either independent check points or having a viewing angle of 39 and using a3D parametric geooverlaid digital vector files. Generally, the measured errors metric correction model were performed with few precise confirmed the predicted errors or were even slightly better, GCPs (Toutin and Cheng, 2000; Davies and Wang, 2001). The and a 2- to 4-m positioning accuracy was achieved for the results of the two research studies demonstrated positioning ortho-images depending upon the elevation accuracy (DEM accuracies of 2 to 3 m and confirmed the high mapping potenand grid spacing). To achieve a better final positioning tial of Ikonos images. accuracy, such as 1 m, a DEM with an accuracy of 1 to 2 m This paper expands on the above-mentioned preliminary and with a fine grid spacing is required, in addition to well- results related to the geometric processing and ortho-rectificadefined GCPs with an accuracy of 1 m.

Snow plays a significant role in surface runoff, groundwater resources, and as an important temporary reservoir for winter precipitation. On the other hand, extreme floods can arise when high melt rates in catchments zone combine with torrential rain at the same time, therefore snowmelt quantities are important for the management of lakes.

This study aims at investigating snow drought characteristics in the catchment area of Lake Urmia, which has recently been faced with the issue of drought and declining water levels. To provide an overview of drought intensity for the last 40 years 1981-2020, the Standardized Snow Melt and Rain Index (SMRI), which accounts for rain and snowmelt deficits, was applied and spatial variations of snow drought were assessed. The index was used in drought analysis based on the ERA5 dataset for the whole study area under three-time scales including the 3-, 6- and 12-month. After determining the dry and wet periods, historical characteristics of droughts were identified, and spatial distribution maps of droughts were plotted.

Results show that during the last years, snow drought events were more frequent, severe, and affected a larger area which shows a spatial spread of drought events. According to the snow index results, most extreme events have happened in the Zarine Rud and Simine Rud sub-catchments which play a key role in increasing the groundwater resources of the Basin. With proper management, these resources can be properly used for lake revitalization.

The aim of this study was to investigate the stability and dynamics of binary culture biofilm formation following antibiotic treatment. Pseudo steady‐state biofilm cultures of clinical strains of P. aeruginosa and B. cepacia concurrently isolated from a single CF patient were established in separate Constant Depth Film Fermenters (CDFFs). Pans, containing established biofilms, were swapped between CDFFs. Biofilms were treated either for 5 days with tobramycin (0.3 mg/ml) prior to pan‐swapping, or with gentamicin (1 mg/ml) immediately following pan‐swapping. In both instances stable binary biofilms were formed. In addition, fresh un‐colonised surfaces added at the time of pan‐swapping and exposed simultaneously to biofilm derived P. aeruginosa and B. cepacia and subjected to antibiotic challenge also established stable binary communities. Treatment of P. aeruginosa and B. cepacia with tobramycin or gentamicin, either prior to or immediately after surface colonisation had little effect on the establishment of stable binary biofilms. Such treatment also had little effect on the immigration of one organism into an established biofilm of a second organism. (© 2005 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)


A multiconfigurational self-consistent reaction-field linear response method was utilized to investigate the hyperpolarizabilities of a solute in an electronically excited state. The excited state is the charge-transfer state in para-nitroaniline and the calculated hyperpolarizabilities are about a factor of 10 larger than the ones for the ground state of para-nitroaniline. The hypolarizabilities were calculated as a function of the dielectric constant of the outer medium. Significant solvent influence on the hyperpolarizabilities of the excited state is reported. The sign and magnitude of the hyperpolarizability components change dramatically with changes of the surrounding medium. ©1999 John Wiley & Sons, Inc. Int J Quant Chem 75: 449–456, 1999

We report the fabrication, characterization, and comparison of four 1.3μm AlGaInAs∕AlGaInAs strain-compensated multiple-quantum-well (SC-MQW) laser structures: (1) sample A—with only an undoped SC-MQW active region, (2) sample B—with an undoped SC-MQW active region and a linear graded-composition (LGC) GaInAsP intermediate layer, (3) sample C—with an n-type modulation-doping (MD) SC-MQW active region, and (4) sample D—with an n-type MD-SC-MQW active region combined with a LGC GaInAsP intermediate layer. The inclusion of either n-type modulation-doped SC-MQW active region or LGC GaInAsP intermediate layer can improve the performance of a laser diode (LD). The LD sample D, which includes both an n-type MD-SC-MQW active region and a LGC GaInAsP intermediate layer, exhibits the best overall performance including a threshold current of 12.5mA, a characteristic temperature of 85K in 20–80°C temperature range, a lasing wavelength shift of 0.38nm∕K, and a relaxation frequency response of 9.9GHz.


The present study investigated the relationship between MLH1, MSH2, MSH3, and MSH6 polymorphisms and toxicity due to platinum‐based doublet chemotherapy for North Indian lung cancer patients. Polymerase chain reaction‐restriction fragment length polymorphism technique was used to assess the polymorphism. For MSH2 IVS1 + 9G > C polymorphism variant type genotype reported a 1.4‐fold increased risk of anemia (AOR = 1.4; 95% CI = 0.98–1.99; p = 0.04) and decreased risk of developing gastrointestinal toxicity (diarrhea) (AOR = 0.53; 95% CI = 0.28–1.01; p = 0.04). Further, we also reported a 10‐fold increased risk of developing severe grade anorexia in combined genotype (GC + CC) (AOR = 9.18; 95% CI = 0.98–86.1; p = 0.05). For MSH2 T > C/‐6 polymorphism, variant type reported a 3‐fold and 2‐fold increased risk of developing severe grade leukopenia (AOR = 3.37; 95% CI = 1.44–7.88; p = 0.005) and neutropenia respectively (AOR = 2.23; 95% CI = 1.07–4.66; p = 0.03). For MSH3 G > A polymorphism, heterozygous (GA) and combined genotype (GA + AA) reported a 7‐fold and 6‐fold increased risk of developing anemia (AOR = 7.23; 95% CI = 1.51–34.6; p = 0.01, AOR = 6.39; 95% CI = 1.53–26.6; p = 0.01). Our results suggest that polymorphisms in DNA mismatch repair genes are associated with hematological, and gastrointestinal toxicities and might be considered a predictor for pretreatment evaluation in lung cancer patients.

ABSTRACT This paper illustrates the new structure of artificial neuron based on root-power mean (RPM) aggregation for quaternionic-valued signals and also presented an efficient learning process of neural networks with quaternionic-valued RPM neurons. The main aim of this neuron is to present the potential capability of a nonlinear aggregation operation on the quaternionic-valued signals in neuron cell. A wide spectrum of aggregation ability of RPM in between minima and maxima has a beautiful property of changing its degree of compensation in the natural way which emulates the various existing neuron models as its special cases. Further, the quaternionic resilient propagation algorithm (ℍ-RPROP) with error-dependent weight backtracking step significantly accelerates the training speed and exhibits better approximation accuracy. The wide spectra of benchmark problem are considered to evaluate the performance of proposed quaternionic RPM neuron with ℍ-RPROP learning algorithm.


Aiming at the problem that particle swarm optimization algorithm is easy to fall into local optimal solution, this paper proposes autonomous groups particle swarm optimization algorithm based on exponential decreasing inertia weight. The exponential decreasing inertia weight is using an exponential function, to adjust inertia weight decreasingly. The algorithm uses the exponential decreasing inertia weight to replace the linear inertia weight of autonomous groups particle swarm optimization algorithm, to better balance global search and local search of the algorithm for improving the algorithm's ability of avoiding falling into local optimal solution. Through the simulation experiments on six benchmark functions, the results show that the exponential decreasing inertia weight better enhances autonomous groups particle swarm optimization algorithm performance. The algorithm has higher ability of avoiding falling into local optimal solution, better stability and better performance in solving high dimensional problems.


This series of papers reviews the literature and reflects on those characteristics of temperate pastures and their management that influence grazing value and sustainability. In temperate environments, pastures provide the primary feed resource for extensively managed livestock. Evidence for the superiority of improved legume-based pastures compared with indigenous pastures is well established; pasture management guidelines that achieve profitable and sustainable livestock systems are well developed; and plant breeding is developing new pasture varieties with genetic improvement in attributes that confer enhancements to seasonal yield, nutritive value and product quality. However, previous pasture research has been undertaken in the context of in situ input-output relationships, and it is proposed that future research needs to broaden its scope to account for impacts on the soil, plant and livestock resources in the wider pastoral landscape. ABSTRACT: The major factor in the innovation of pasture technology in Australia has been the contribution of pasture improvement, namely the dual practice of sowing adapted legumes and fertilising with superphosphate. Pasture improvement based on white clover and superphosphate has been very successful, but by the 1980's poor persistence of imported cultivars emerged as a major problem; a local program of white clover improvement has been underway since 1987. For subclover-based pastures, there is a 40 million ha gap between the area currently planted and the potential area; research to determine whether this gap is due to technical or economic constraints is of high priority. Future pasture research will be supported by advances in economic analysis and environmental statistical modelling. As sustainability and resource use issues become more prominent in the public debate, new practices will be evaluated by economic analysis that considers consequences for stocks of pasture, soil, and livestock resources in addition to traditional input - output considerations. Statistical modelling has the power to exploit non-treatment variability for more efficient design and greater precision of analysis, and allows utilisation of large and complex data-sets for predictive purposes.


The hair transplant surgeon has a responsibiJiry to understand the psychological needs of the patient. The practitioner needs to recognize how these needs evolve and are attached in a subliminal way to those aspects of society that present as amorphous and mythical, yet directly underpin the cultural experience of everyone. The hair transplant surgeon needs to be able to listen and encourage the patient to talk about his self-esteem, frustrations, self-image, distress, and fears. To ignore these emotions is a disservice to the patient. The psychology of hair loss is tied to masculinity, sexual attractiveness, and aging, whether real or imagined. What the patient is experiencing is a microcosm of the big picture. For example, loss of masculinity is often associated with losing one's hair. What is masculinity? Webb (1998:16) describes it as "a value whose arrival is always being heralded but never quite arrives ... a wished-for state always delayed and it may be taken away by other men." This state, as identified by Webb in his book junk Male, offers flesh to the stereotypical construct where body and soul form a harmonious whole with every part in its place. The image of the solid stomach, the hard muscles, and the power of will provide a standard mental picture of the outward appearance by which we may judge the worth of the male. All men are expected to conform to an ideal of masculinity as this expresses an inner worth and at the same time is made to reflect the strength of the society. Gender permeates many cultural arenas-sports, film, music, and literature-and often the presence is an unconscious one. The concept of


Abstract In this paper we establish the Nehari manifold on edge Sobolev spaces and study some of their properties. Furthermore, we use these results and the mountain pass theorem to get non-negative solutions of a class of edge-degenerate elliptic equations on singular manifolds under different conditions.


Scientists are increasingly moving towards ensemble data sets to explore relationships present in dynamic systems. Ensemble data sets combine spatio-temporal simulation results generated using multiple numerical models, sampled input conditions and perturbed parameters. While ensemble data sets are a powerful tool for mitigating uncertainty, they pose significant visualization and analysis challenges due to their complexity. We present a collection of overview and statistical displays linked through a high level of interactivity to provide a framework for gaining key scientific insight into the distribution of the simulation results as well as the uncertainty associated with the data. In contrast to methods that present large amounts of diverse information in a single display, we argue that combining multiple linked statistical displays yields a clearer presentation of the data and facilitates a greater level of visual data analysis. We demonstrate this approach using driving problems from climate modeling and meteorology and discuss generalizations to other fields.

The uncertainties in the measurement of the eardrum impedance at low frequencies due to the microphone placement and/or due to the transfer function of the source can be avoided through the use of a velocity‐controlled source, combined with a single pressure measurement at the source. Due to the reciprocal spreading between the source size and the number of higher order acoustic wave components, the source should be of as large a diameter as possible. At high frequencies, the eardrum impedance can be determined via pressure measurements with a half‐wavelength long microphone, of arbitrary cross‐sectional area, which distorts neither the measured (plane wave) pressure nor the eardrum pressure. Schemes for the absolute calibration for such a measuring system will be described also.


The phenomena implied by the existence of quantum vacuum fluctuations, grouped under the title of the Casimir effect, are reviewed, with emphasis on new results discovered in the past four years. The Casimir force between parallel plates is rederived as the strong-coupling limit of δ-function potential planes. The role of surface divergences is clarified. A summary of effects relevant to measurements of the Casimir force between real materials is given, starting from a geometrical optics derivation of the Lifshitz formula, and including a rederivation of the Casimir–Polder forces. A great deal of attention is given to the recent controversy concerning temperature corrections to the Casimir force between real metal surfaces. A summary of new improvements to the proximity force approximation is given, followed by a synopsis of the current experimental situation. New results on Casimir self-stress are reported, again based on δ-function potentials. Progress in understanding divergences in the self-stress of dielectric bodies is described, in particular the status of a continuing calculation of the self-stress of a dielectric cylinder. Casimir effects for solitons, and the status of the so-called dynamical Casimir effect, are summarized. The possibilities of understanding dark energy, strongly constrained by both cosmological and terrestrial experiments, in terms of quantum fluctuations are discussed. Throughout, the centrality of quantum vacuum energy in fundamental physics is emphasized.

The extraordinary preferred standpoint of ionic liquids as solvents and catalysts and different alluring properties in organic chemistry, the preparation, and utilization of ionic liquids have pulled in important interest. In this Paper, we report a series of ammonium and pyridinium ionic liquids which have been synthesized and characterized. These ionic liquids are easy to prepare from amine and pyridine and acids. They have been utilized as catalysts and naturally favorable solvents for esterification of some aromatic acids. Since, esters are vital natural solvents, fundamental chemicals and pharmaceutically interesting chemicals which are broadly utilized as a part of the related industry. The results demonstrate that these ionic liquids are effectively isolated and reusable without losing their action and quality. On the other hand, the conversion and yield got from esterification utilizing these ionic liquids are essentially high. The separation of the desired product was generally performed by extraction with dichloromethane or ethyl acetate and water. The ionic liquids are reused after removal of water under vacuum at high temperature.


Novel excellent hydrophobic- mesoporous- polymer-based solid acid catalysts have been successfully synthesized by copolymerization of divinylbenzene (DVB) with sodium p-styrene sulfonate (H-PDVB-x-SO3H's) under solvothermal conditions. N2 isotherms and TEM images showed that H-PDVB-x-SO3H's have high BET surface areas, large pore volumes, and abundant mesoporosity; CHNS element analysis and acid–base titration technology showed that H-PDVB-x-SO3H's have adjustable sulfur contents (0.31–2.36 mmol/g) and acidic concentrations (0.26–1.86 mmol/g); TG curves showed that H-PDVB-x-SO3H's exhibited much higher stability of the active site (372 °C) than that of the acidic resin of Amberlyst 15 (312 °C); contact angle and water adsorption tests showed that H-PDVB-x-SO3H's exhibited excellent hydrophobic properties. Catalytic tests in esterification of acetic acid with cyclohexanol, esterification of acetic acid with 1-butanol, and condensation of benzaldehyde with ethylene glycol showed that H-PDVB-x-SO3H's were mo...

Original Research Article Background: Enteric fever is a common public health problem in Bangladesh. Antibiotic therapy is the choice of treatment but development of resistant to common antimicrobial drugs complicates the problem now a days. Methodology: This prospective observational study conducted in a tertiary care hospital at Dhaka from March to December 2016 among suspected case of Enteric fever as per case definition. Results: Among 212 suspected enteric fever 117 children were diagnosed as enteric fever by blood culture and/or widal test. Male: female were 1.3: 1. Maximum (70%) children were in age group 5 years or more. Most of the children were from urban slum area (53.6%) of Dhaka city. Cases were admitted throughout the year. Common presentation were fever (100%), anorexia (100%), pain abdomen (74.4%) and loose motions (46.1%). The common signs were hepatomegaly (41.9%), hepatosplenomegaly (5.1%) coated tongue (64.9%), pallor (74.4%). The complications rate was 35.9% and commonest being UTI and pneumonia. The overall positivity of widal test was 89.7% and the culture positivity was 32.5%. Among isolates, 94.7%were Salmonella typhiand 5.3% Salmonella paratyphi A. Among them18.1% isolates were multi drug resistant. Amoxyclav, Amoxycilline and Nalidaxic acid were 100% resistant whereas Cefixime, ceftriaxone. Meropenam and Ofloxacine were 100% sensitive. Ciprofloxacin was 72.2% sensitive among isolates. The most important macrolides, Azithromycin was only 22.2% sensitive among S.Typhi in this study. Conclusion: Enteric fever is most prevalent during summer & rainy session. WASA supplied water may play a role. Hepatomegaly is common. UTI and pneumonia are the commonest complication. Multidrug resistant cases are not so as high as other countries. Cefixime, Ceftriaxone. Meropenam and Ofloxacine are the drugs of choice. Ciprofloxacin is still could be chosen for the treatment of enteric fever. Higher rate of resistant to Azithromycin is alarming.

Abstract– Embryonic sensory neurons have an absolute requirement for the nerve growth factor to survive and grow fibers, at least in vitro. We have now shown that the inorganic cations, magnesium and potassium are also necessary for the survival of these cells. On the other hand, calcium is not needed for the survival of the sensory neurons, but is needed for the neurons to grow fibers. Therefore, by changing the concentration of calcium ions in the culture medium it is possible to separate the two actions (survival and fiber outgrowth) of the nerve growth factor on sensory neurons.


Based on the concept of persistent excitation (PE), a deterministic learning algorithm is proposed for neural network (NN)-based identification of nonlinear systems recently. This paper investigates the quantitative relationship between the PE levels (including the level of excitation), the architectures of NNs and the convergence properties of deterministic learning, which is motivated by a practical problem of how to construct the NNs in order to guarantee sufficient level of excitation and identification accuracy for specific system trajectories. The results on PE levels are utilized to analyze the deterministic learning performance. It is proven that by increasing the density of NN centers, the approximation capabilities of NNs increase but the level of excitation decreases, which means that a trade-off exists in the convergence accuracy when adjusting NN architectures.


ibet's imperial period (c. 600–850) holds a central position in many traditional Tibetan histories, especially the depiction of how the emperors of that time established Buddhism in "the land of snows" by inviting Dharma practitioners from surrounding states. These narratives less often emphasise the mundane aspects of the empire, the conquests and international diplomacy that made Tibet at this time a dominating force in Central Asia. Even the Fourteenth Dalai Lama, despite receiving a thorough monastic education in religious history, did not learn about Tibetan imperial achievements when young. Then, in 1954, he visited Xi'an, which was once the ancient western Chinese capital of Chang'an:


The article is dedicated to the particularities of the self-conception of the teenagers deprived of the paternal guardianship. The particularities were brought to light by the aid of the tests by G. Kelly using the projective stimulant material of M. Lusher and exclusive of that. All that provided means of scrutiny of the realizable and not-realizable levels of the self-conception. Investigated were cognitive and emotional substructures of the self-conception: the system of personal constructs of social orphans, its cognitive complexity, friability-inflexibility or rigidity as well as factor structure of personal constructs and positiveness-negativeness of self-appraisal of the teenagers.


We consider a double two-level system in which each single two-level system is driven by a strong linearly polarized pulse. The system is probed by a weak pulse or- thogonally polarized. We study the distortion experienced by the probe temporal envelope when the relative phase between the pump and the probe is varied. We show that pulse be- havior oscillates between two regimes that corresponds to transparency and amplification respectively. Interpretation of this effect is given within adiabatic representation.


We provide an extreme value analysis of the returns of Bitcoin. A particular focus is on the tail risk characteristics and we will provide an in-depth univariate extreme value analysis. Those properties will be compared to the traditional exchange rates of the G10 currencies versus the US dollar. For investors, especially institutional ones, an understanding of the risk characteristics is of utmost importance. So for Bitcoin to become a mainstream investable asset class, studying these properties is necessary. Our findings show that the bitcoin return distribution not only exhibits higher volatility than traditional G10 currencies, but also stronger non-normal characteristics and heavier tails. This has implications for risk management, financial engineering (such as bitcoin derivatives) — both from an investor's as well as from a regulator's point of view. To our knowledge, this is the first detailed study looking at the extreme value behavior of the cryptocurrency Bitcoin.


a b s t r a c t In the wake of adoption of the resolution by the International Maritime Organization to control biofouling on vessels, which is recognized as a major vector for transfer of invasive species, this study attempts to create a baseline data on major hard-shelled biofouling organisms in the harbour waters. This study was primarily focused towards understanding the biofouling and corrosion pattern on various metals and their performance under immersed condition in a marine environment, at 0.3 and 3.0 m depths. Furthermore, the study attempts to understand the surface dependent characteristics of barnacle base plate and its adhesion strength. Barnacle, mussels and oysters were the major fouling organisms accounting for 72.33% of the variation. Stainless steel and Titanium panels showed the highest average biofouling load of 176.36 and 168.35 g/300 cm 2 , respectively. The variance in biofouling between metals and depths was highly significant at p < 0.001 and p < 0.01, respectively. Morphology of barnacle base plate interfacial surface varied between metals. Barnacles with 8-9 mm base diameter showed the maximum adhesion strength in shear of 6.86 ± 0.95 kPa. © 2013 Elsevier B.V. All rights reserved.


Introduction "May you live in interesting times". So goes the ancient proverb, and these are certainly interesting times for the Canadian health systems, and thus the Canadian Healthcare Association (CHA). The last year has brought a great deal of change and unanticipated developments. Within a few short months, widely held expectations have been largely turned on their head and an entirely new dynamic has emerged in the politics of Canadian healthcare.


Harmonic analysis is a powerful tool to characterize and quantify current-induced torques acting on magnetic materials, but so far it remains an open question in studying antiferromagnets. Here we formulate a general theory of harmonic Hall responses of collinear antiferromagnets driven by current-induced torques including both field-like and damping-like components. By scanning a magnetic field of variable strength in three orthogonal planes, we are able to distinguish the contributions from field-like torque, damping-like torque, and concomitant thermal effects by analyzing the second harmonic signals in the Hall voltage. The analytical expressions of the first and second harmonics as functions of the magnetic field direction and strength are confirmed by numerical simulations with good agreement. We demonstrate our predictions in two prototype antiferromagnets, α−Fe2O3 and NiO, providing direct and general guidance to current and future experiments.


Pulse laser oscillations from multiple ionized N, O and rare gases were observed in the ultraviolet region for Z-pinch discharge. The optimum value of gas pressure, oscillation time and its pressure dependence were examined for laser oscillations and it was found that oscillations from different ions occurred in the increasing order of ionization after the breakdown of discharge. The line ArII λ4765 A showed an anomalous behavior. Calculations were made on two different models for ionization and excitation of plasma. The first model was concerned with ionization and excitation by thermal electrons during plasma compression, and the second one with direct excitation of laser oscillation by runaway electrons. The calculation based on the former explained the temporal sequence of laser oscillations and that on the latter explained the anomalous behavior of ArII λ4765 A line.

The title compound, 6-cinnamoyl-5-hydroxy-2,2,8,8-tetramethyl-2H,8H-pyrano[2,3-f]chromene, C 25 H 24 O 4 , is an angular benzodipyran system. It contains a central tricyclic core and a peripheral aromatic ring. The central ring of the tricyclic core is fully substituted while the pyran rings on either side are each unsubstituted at two sites. The central fully substituted ring is planar within 0.014 A. One pyran ring is planar to within 0.041 A, but the second pyran ring is only planar to within 0.156 A; this may be attributed to an intramolecular C-H...O contact of 2.30 A. The structure is stabilized by intramolecular O-H...O hydrogen bonds.

The history book "An Nam so hoc su luoc" was edited by French scholars in the period when the colonial government reformed the education system in Vietnam with the purpose to split Vietnam from Chinese influences, and for a long term to make Vietnam to become a dependent country of France. This was the first time, the history subject was introduced into curriculum of general education for Vietnamese learners, and this was totally different from traditional examination for thousand years ago. In addition, with the Western modern design and edition, Vietnamese historical books had significant changes in terms of contents that was foundation for later book design. Apart from negative contents which serve exploiting and dominating of colonial government, the book "An Nam so hoc su luoc" as well as other Vietnamese historical books at that time were valuable document for scientific research.

Glycerol-induced hyperhydration (GIH) has been shown to improve fluid retention and endurance performance, compared with water-induced hyperhydration. The goal of this article is to report on what is known and unknown about how glycerol-containing hyperhydration solutions (GCHS) are processed at the stomach and intestine level, propose strategies to improve the efficacy of GIH and provide research questions for future studies. Through statistical analyses, it was demonstrated that the effectiveness of GCHS in increasing fluid retention is maximized when fluid ingestion is in the upper range of what is normally administered by studies (~26 ml × kg bodyweight) and the duration of the protocol is no longer than the time it takes for the glycerol-fluid load to be totally or nearly completely integrated inside the body. The rate of gastric emptying and intestinal absorption of GCHS is unknown. However, based upon an analysis of indirect evidence obtained from human studies, it is proposed that most glycerol (~80 g) and fluid (~1700 ml) ingested during a typical GIH protocol can be integrated inside the body within 60 to 90 min. Whether the stress associated with competition could alter these figures is unknown. Research in rats indicates that combining glycerol with glucose at a 3:1 ratio accelerates the intestinal absorption of both glycerol and water, thereby potentially improving the efficacy of GIH. Human studies must be conducted to determine how GCHS are processed by the gastrointestinal system and if adding glucose to GCHS could improve the technique's efficacy.


The aim of the paper is to present the influence of the solar radiation variation on the performances of a stand alone photovoltaic pumping system which consists of photovoltaic generator, dc–ac inverter, an immersed group motor-pump and control box. The system was installed at the faculty of Engineering and Technology, University of Gezira. The incorporation of photovoltaic systems in water pumping applications is thought to be one of the most popular and ideal uses of solar energy exploitation, especially under the common allegation of coincidence between solar insolation and water demand. From the obtained results, we will show that the decrease of the solar radiation degrades performance (solar generator voltage, inverter voltage and the flow rate) of the photovoltaic pumping system. The total performance of the pump is mainly dependent on the specification of the equipment used. Key words: solar radiation, photovoltaic pump, photovoltaic generator, solar insolation, dc-ac inverter


Abstract : The Mach-6 tunnel continues to run quiet to moderately high Reynolds numbers. Quiet flow was degraded in 2010 when the throat was opened, but a thorough repolishing of the throat resulted in a significant improvement in performance. Since the nozzle-wall boundary layer remains laminar more than 10 inches downstream of the exit to unit Reynolds numbers near 3.5 million per foot, unprecedented quiet-flow Reynolds numbers can now be achieved on slender models. The tunnel is operated by a single graduate student, with good reliability, and a large amount of data can be obtained during each run using a variety of sensors. Instability and transition measurements were carried out on various models to study the second-mode and crossflow instabilities, the instabilities behind an isolated roughness, the development of second-mode wave packets and turbulent spots, the general effects of roughness and tunnel noise, the effect of tunnel noise on oscillations in a forward-facing cavity, and other phenomena. The research resulted in 17 conference papers, 8 Master's theses and 2 Ph.D. theses. A brief summary is reported here, along with selected highlights.


One of the main challenges that construction industry faces today is how to address the demands for more sustainable, environmentally friendly and carbon neutral construction materials and building upkeep processes. One of the answers to these demands is lime-hemp concrete (LHC) building materials - carbon negative materials that have sufficient thermal insulation capabilities to be used as thermal insulation materials for new as well as for existing buildings. But one problem needs to be overcome before these materials can be used on a large scale - current manufacturing technology allows these materials to be used only as self-bearing thermal insulation material with large labour intensity in the manufacturing process. In order to lower the labour intensity and allow the material to be used in wider applications, a LHC block and board production is necessary, which in turn calls for the binders different from the classically used ones, as they show insufficient mechanical strength for this new use. The particular study focuses on alternative binders produced using gypsum-cement compositions ensuring they are usable in outdoor applications together with hemp shives. Physical, mechanical, thermal and water absorption properties of hemp concrete with various binders are addressed in the current study.


In this paper we introduce an in-hospital navigation system suitable for motor impaired, visually impaired and elderly people. GPS localisation and Wi-Fi triangulation are often not suitable in indoor environments due to poor signal or complicated calibration. We present a navigation system that does not depend on precise electronic localisation aids. User interfaces used are automatically accustomed to target user's abilities and preferences. Four different terminal types are used for the navigation system prototype.


For understanding the cement hydration composed of high C₃A content, pure clinker phases such as Alite, Tricalcium aluminate (C₃A) were synthesized and five different compositions of mixtures were prepared. The hydration of samples were followed by calorimetry. Quantitation of the crystalline and amorphous products were conducted by X-ray diffraction and Rietveld analysis. It was found that the hydration between C₃A and Gypsum was accelerated by hydration of Alite. It was implied that amorphous materials produced from the hydration between C₃A and Gypsum as well as the hydration of Alite. Rise of pH due to precipitation of portlandite from Alite hydration accelerated the hydration between C₃A and Gypsum. It could be explained on the basis of thermodynamic equilibrium theory that AFm phase with low sulfate content precipitated in the vicinity of C₃A particle. In the bulk solution far from the surface of C₃A, AFt with high sulfate content precipitated. Subsequently, because of low sulfate content in AFm, mass transfer into C₃A particle kept proceeding and hydrating C₃A continuously progressed. That is why hydration reaction of C₃A proceeds when added Alite in contrast to the hydration without Alite.C₃A含有量の多いセメントの水和反応について理解することを目的とし、その主たる反応を司るAlite、C₃A、Gypsumを混合したモデルセメントの水和実験を行った。発熱量測定、XRD・リートベルト解析、TG-DTA測定の結果、Aliteの水和反応がC₃A-Gypsum系の水和反応を促進させることを確認した。さらに、その要因はAliteの水和反応からPortlanditeが生成することによるpH上昇であり、その際C₃A粒子付近に析出するAFm相に含まれるSO₄²⁻量が少ないため、未水和C₃Aへの物質の透過が継続するからであることが示唆された。


A quantitative analysis of angular orientation and locomotor activity of 80 sea catfish (Anus fe!is) over 12 consecutive months, under controlled conditions of photoperiod, temperature, and water quality, revealed non-random oscillations in the monthly mean orientation vectors and monthly mean activity ofthe experimental population. Marquardt modeling of monthly mean activity and of the sine and cosine components of monthly mean orientation indicated significant annual, bimodal cycles for all three variables. These cycles correlated with the observed, seasonal inshore-offshore migrations of A. ftlis, as documented in the literature, and had significant periods of 11.40, 5.11, and 6.64 months for the sine and cosine components of orientation and for activity, respectively. Photoperiod alone apparently acted as the exogenous cue triggering these cyclic changes in orientation and activity.


This paper uses the method of spatial measurement to explore the interaction of smog pollution between local and remote areas in 31 provinces in China and the impact of economic changes. Global spatial correlation analysis shows that there is significant spatial positive correlation of smog pollution, and local spatial correlation shows that the high concentration of pollution is distributed in Beijing-Tianjin-Hebei and adjacent Shandong, Henan, Liaoning, based on environmental Kuznet The curve (also known as the EKC curve) found that smog pollution is closely related to the growth of the main business income, and the inverted U-shaped relationship between smog pollution and economic growth does not exist or has not yet appeared. That is to say, with the growth of the main business, the pollution level is rising continuously. The comprehensive empirical analysis shows that the spatial spillover effect of smog pollution is particularly obvious. The high pollution concentration area is affected by the neighboring areas, and it is difficult to obtain all the benefits from the implementation of environmental regulation. It is imperative to control smog and strengthen inter-regional joint defense.


Interest in New Education Pedagogy is currently is experiencing its renaissance. The solutions suggested by alternative education, which emphasise the development of students' individual skills and also addressing their needs and interests seem to be better suited to present times. The pedagogy of New Education, which places children in the centre of the educational and formation process, undoubtedly has much to offer. When reflecting on contemporary methods of making use of the achievements of New Education, it is worth going back to its origins, even to those little known or even forgotten and almost absent in current academic discourse as exemplified by the pedagogical reflection of the outstanding Russian intellectual and novelist, Leo Tolstoy (1828-1910). This article is dedicated to recalling the basic educational and formational intuitions of this exceptional figure. This seems to be intentional for at lease three reasons. First, as Sergiusz Hessen stated, it was Tolstoy who laid the groundwork for the New Educational pedagogy in Russia, which was referred to there as Free Education. Secondly, Leo Tolstoy's pedagogical views and initiatives in the spirit of New Education, if establishing a school in Yasnaya Polyana can be acknowledged as such, appeared almost half a century earlier than John Dewey's My Pedagogic Creed Ellen Key's The Century of the Child. Finally, and equallyas important, the 190's anniversary of Leo Tolstoy's birth will be celebrated next year.

The decarbonylation of [Re 2 (CO) 10 ] on ultrathin MgO(111) films (∼50 A) grown on a Mo(110) substrate was investigated with infrared reflection-absorption spectroscopy and temperature-programmed desorption/decomposition. When [Re 2 (CO) 10 ] was adsorbed at 320 K, it reacted with the MgO(111) surface, forming a rhenium subcarbonyl, [Re(CO) 4 {OMg}] 2 , where (OMg) represents oxygen on the MgO(111) surface. Upon heating to temperatures >400 K, [Re(CO) 4 {OMg}] 2 was decarbonylated, forming [Re(CO) 3 {OMg} 3 ]


the electrical behavior of conducting carbon whisker reinforced thermoplastic elastomer (TPE) composites was investigated. The carbon whiskers were produced by a catalytic chemical vapor deposition (CCVC) process. The electrical properties of the composite were characterized as a function of temperature and deformation. The electrical resistivity of the composite can be varied by uniaxial deformation and by temperature. The temperature-resistivity studies indicated that the resistivity of these composites were influenced by the glass transition temperature of the TPE. the resistivity v. 1/T curves exhibited two distinctive negative slopes that intersected at the Tg of the elastomer. This as correlated to the Tg of the rigid segments in the TPE as obtained by the dynamic mechanical thermal analysis. Further, uniaxial deformation studies at room temperature demonstrated that the resistivity increased exponentially with the deformation. Mechanical and electrical properties of the composites indicated that CCVD carbon whiskers can be used to improve the strength and electrical conductivity of TPEs. The change is resistivity (up to 5 orders of magnitude) of the composites with respect to deformation and/or temperature can find use in electromechanical and electrothermal applications.
