This paper discusses one intriguing but complicated issue about identity in tautological constructions in Chinese political discourse. We recognized that, though Russell's description theory is helpful to exploit the logical mechanism underlying the grammatical forms, it still has the difficulties in describing the relationship between logic and language experience. That's why we talked about Grice's theoretical contributions. And finally, we find an ideal theory to describe the relationship between them.

In order to study the effect of Direct Current bias on the excitation current of 1000kV UHV transformer caused by the parallel operation of DC transmission and AC transmission, this paper builds a simulation model of 1000kV three-winding autotransformer based on MATLAB/Simulink This paper introduces the simulation model of simulation model parameters, and builds a simulation model of 1000kV UHV AC transmission system. Based on the analysis of the change trend of excitation current when the DC voltage source is applied at the neutral point of the transformer, 1000kV transformer, the conclusion is that the DC bias suppression measures and the transmission line design work to provide a theoretical reference.


The concepts of «information culture» and «universal educational actions» of school students are regarded. It is argued that the phenomena of information culture and universal educational actions have a common psychological basis, that the development of universal edu cational actions is conditioned by the state of the development of information culture of the school student. The results of the preliminary research of relations of levels of information cul ture with levels of universal educational actions are presented.


Democratic policymaking requires compromise, but public support for it varies substantially. Scholars know relatively little about the psychology of such public attitudes. In this investigation, we consider the predictive capacities of humanitarianism (a commitment to helping those who are suffering) and egalitarianism (a commitment to treating people equally). Such altruistic values, we argue, foster concern for the common good and a cooperative vision of democratic policymaking — which, in turn, engender support for compromise. Moreover, we suggest that partisan differences in such values (with Democrats being more likely than Republicans to prioritize them, on average), help explain Democrats' disproportionate support for compromise. Data from two nationally representative studies are consistent with this theoretical perspective, offering novel insights into the roots of political compromise, the reach of core values as political determinants, and the dynamics of partisan asymmetry.


This paper investigates the reasons that lead migrants to performmultiple migrations in Spain. After describing the main features of these immigrants,we specify a binomial logit and multinomial probit in which the probabilityof re-migration depends on the personal characteristics of individuals and thecorresponding origins and destinations of their migratory paths. The informationused comes from the microdata of the Residence Variation Statistic. Results indicatethat repeated migration of nationals and non nationals respond to differentreasons. The analysis suggests that foreigners' re-migrations depend on the results of their labor experiences, whereas other reasons can be found in those ofSpaniards.

Thermoelectric materials have been of interest for several decades due to their ability to recapture waste heat of various systems and convert it to useful electricity. One method used to improve the thermoelectric efficiency of a material is to reduce the lattice thermal conductivity ( k _ p ) while not affecting the other properties. In order to reduce the k _ p of the material, this paper introduces silicon (Si) nanoparticles (NPs) in Mg_2Si to manipulate phonon scattering and mean free path. A series of simulations is performed with the metal silicide thermoelectric material Mg_xSi_x. The objective of this work is two-fold: 1) to determine the optimal Si nanoparticle (NP) concentration and 2) to determine the optimal Mg_xSi_x stoichiometry for minimizing the k _ p of the system. It should be noted, however, that the assumed reduction in thermal conductivity is only a result of reduced phonon transport and that minimal impact is made on the transport of electrons. Interestingly, the uniform off-stoichiometry (49.55 atomic percent ( a/o ) Si) sample of Mg_xSi_x resulted in a reduction of k _ p of 84.62 %, while the Si NP sample, with matching a/o Si, resulted in a reduction of k _ p of 78.82 %.


Volume 1, Issue 3 September-October 2012 Page 75 Abstract: Text classification is the automated assignment of natural language texts to predefined categories based on their content. Text classification is the primary requirement of text retrieval systems, which retrieve texts in response to a user query, and text understanding systems, which transform text in some way such as producing summaries, answering questions or extracting data. Now a day the demand of text classification is increasing tremendously. Keeping this demand into consideration, new and updated techniques are being developed for the purpose of automated text classification. This paper presents an algorithm for text classification. Describe the three algorithms that we compare: the k nearest neighbors classifier, naive Bayes and the Support Vector Machines. Last, we define the settings of our scenario and the data on which we performed our experiments on.

The necessity for the interregional differentiation of national assistance arises from the general perception that existing regional policies are ineffective to accomplish the balanced regional development. Existing regional policies and implementation system have limited capabilities to contribute substantially to the balanced territorial development. There is a growing need to enhance balanced interregional development through the redistribution of national resources by differentiating government assistance depending on the development level. The study attempts to categorize regions using statistical data on various aspects of regional development. Fifteen social and economic indices were employed to classify all of the 232 localautonomous regions throughout the country. A cluster analysis using the SPSS identified groups of regions according to the level of development. The first and most advanced group includes 53 regions; the second and third group include 71 and 60 regions respectively; and the last and most depressed group includes 48 regions. The study suggests the spatial policy framework that reflects diff e rential characteristics according to this grouping of regions.


The nuclear receptor (NR) superfamily is the largest known family of transcription factors in eukaryotes. In the 1980's when the size of the NR family and the scope of the functions of its members were being discovered, tissue distribution studies revealed that the mRNAs of many of these receptors were expressed in the central nervous system. The difficult task of uncovering the functions of these receptors in the brain is still ongoing. In this thesis the functions of two of the members of the NR superfamily have been studied: the estrogen receptor β (ERβ) and the liver X receptor β (LXRβ). ERβ knockout (ERβ) mice have provided evidence for a role for ERβ in neuronal survival in both the developing and in the adult brain. When proliferating cells were labeled with 5'-bromodeoxyuridine (BrdUrd) between embryonic day (E) 14.5 and E16.5 fewer BrdUrd-labeled cells could be detected in the upper cortical layers by E18.5 and postnatal day 14 in mice lacking ERβ. The migration of these neurons seems to be impaired and the processes of the cortical radial glia, which are essential for guiding the migrating neurons, were fragmented. In addition, more apoptotic cells were detected in the ventricular zone of ERβ mice at E18.5. By influencing migration and neuronal survival, ERβ has an important function during brain development. Adult ERβ mice show regional neuronal hypocellularity, especially in the cerebral cortex, and proliferation of astroglial cells in the limbic system. The neuronal deficit becomes more pronounced as ERβ mice age, indicating a neuroprotective role for ERβ. By 2 years of age there is degeneration of neuronal cell bodies throughout the brain and this is particularly evident in the cortex and the substantia nigra. During embryonic development there is a limited exposure of the brain to 17βestradiol, and this raised the question of whether ERβ is ligand-activated during this stage. We have examined the possibility that an alternative ligand for ERβ in the developing brain is 5α-androstane-3β, 17β-diol (3βAdiol). In mice, in which the pathway for degradation of 3βAdiol is inactivated (CYP7B1 knockout mice), there is an increase in the number of neurons in the brain and a profound decrease in apoptosis between E13.5-15.5. The enlargement of the brain persisted to 14 days postnatally but brain size was normalized by the time mice were 3 months old suggesting that the excess cells must have been removed in the late postnatal period. These data are supportive evidence for a role for the ERβ-3βAdiol-CYP7B1 pathway in regulation of neuronal survival in the embryonic brain. LXRβ is an oxysterol-activated nuclear receptor that plays a crucial role in the regulation of cholesterol and sterol trafficking between tissues. In LXRβ knockout mice motor co-ordination is impaired when male mice are 7 months of age. This phenomenon is associated with lipid accumulation and loss of motor neurons in the spinal cord, together with axonal atrophy and astrogliosis. Several of these features are reminiscent of the neuropathological signs of chronic motor neuron disease such as amyotrophic lateral sclerosis. We speculate that absence of LXRβ leads to pathological accumulation of sterols and lipids that may themselves be neurotoxic or may modulate intracellular pathways and thereby predispose motor neurons to degeneration.

Expanding the expectation E(X − Y )2, one finds that the distance is obtained by maximizing E(XY ), or, equivalently, by maximizing Cov(X,Y ). For a random variable U that is uniformly distributed on [0, 1], take X∗ = F−1(U) and Y ∗ = G−1(U). Then X∗ ∼ F , Y ∗ ∼ G and the distribution function of (X∗, Y ∗) is given by H∗(u, v) = min(F (u), G(v)). Clearly, for any joint distribution of X ∼ F and Y ∼ G, we have H ≤ H∗. By Hoeffding's inequality, this means Cov(X,Y ) ≤ Cov(X∗, Y ∗). Thus,


We present SSD, Software for Systems with Delays, a de novo MATLAB package for the analysis and model reduction of retarded time delay systems (RTDS). Underneath, our delay system object bridges RTDS representation and Linear Fractional Transformation (LFT) representation of MATLAB. This allows seamless use of many available visualizations of MATLAB. In addition, we implemented a set of key functionalities such as H2 norm and system gramian computations, balanced realization and reduction by direct integral definitions and utilizing sparse computation. As a theoretical contribution, we extend the frequency-limited balanced reduction to delay systems first time, propose a computational algorithm and give its implementation. We collected two sets of benchmark problems on H2 norm computation and model reduction. SSD is publicly available in GitHub at https://github.com/gumussoysuat/ssd. Our reproducible paper and two benchmark collections are shared as executable notebooks.

ABSTRACT Student preferences for delivery options were obtained within a monetary framework by asking students to purchase their ideal course structure. Results show that accounting students prefer to spend more on tutorials but purchase less lecture time; the difference due to the higher cost of tutorials compared to lectures. Face-to-face classes were preferred to web-based materials. Within lectures and tutorials students prefer more time devoted to teacher-centred activities than student-centred activities. Monetary valuations, where students must take into account the cost of delivery as well as effectiveness, provide insights for teaching staff and administrators, who need to simultaneously enhance teaching and learning, satisfy student preferences and operate with limited resources. Online and/or student-centred learning may not be compatible with preferences of accounting students. Teachers need to balance calls to change educational delivery and learning activities with preferences of accounting students, or ensure they educate students on why non-preferred approaches are undertaken.


The mass media is a weapon for the patriarchal ideology to implant into the minds of the public. Through the news that is gender bias, the media can influence public's political attitudes to fight for women's representation in parliament. The purpose of this study is to determine how Kompas does the framing about the figure of DPR RI Female Legislators from 2009 to 2014 period. In order to achieve the goals, this research is done by using muted group theory as one variant of the theories that explains the "silencing/muting" language study through the language of the dominant group. By using constructionist paradigm, research is conducted using qualitative method and Zhongdang Pan and Gerald M. Kosicki framing analysis. The subjects of this study are the news about DPR RI female legislators 2009-2014 period from the printed version/newspaper of Kompas in 2009 and 2014. The result of this study shows that the news in Kompas contributes to the perpetuation of patriarchal ideology. The perpetuation of this ideology is shown on the news regarding the role of female legislators on domestic issues to strategic political issues. Apparently, Kompas is not only silencing/muting women through the usage of language patterns, but it is also followed by the framing of the news that prioritizes the popularity aspect of female legislators as the entertainers (name makes news) that gives rise to the "taming", stereotyping gender: domestication, and marginalization through "silencing/muting" and the appearance of "trivialisation" or "disparagement" element of the female legislators. To face problems like this, the audience should become more media-literated. The media people shall also not be trapped into "lazy journalism". It is the challenge for the activists and female politicians to convince the young professional journalists in order not to be enslaved by stereotypes that degrade women's achievements in politics by providing insight about gender equality.

Pig detection is vital to pig farms since it is the basis for counting, weight estimation, and behavior recognition functions. Existing methods focused on white pig detection instead of black pigs because the contrast between white pigs and the background is more evident than black pigs, making black pig detection more challenging. Furthermore, pig farms often suffer from insufficient light, and pigs tend to be stacked together, which makes it hard to detect pigs accurately. To this end, we propose a black pig detection method, based on YOLOV4, robust to both crowd scenes and low-illumination conditions. The method consists of the following parts: 1) generate domain adaptation dataset (DAD) based on style-transfer to optimize the original data distribution, therefore improving the performance of the method for low-illuminated conditions; 2) propose a crowd-aware module (CAM), adapted to YOLOV4 backbone architecture, to generate crowd density maps; 3) develop an adaptive attention module (AAM) to fuse YOLOV4 backbone features with corresponding crowd density map allowing the method robust to pigs in the crowd. The experimental results confirm the feasibility of this method. The mAP value in fully-lighting and poorly-lighting increased to 88.95% and 84.74%, respectively.


Linear element is the largest various element in the map.Line simplifying is very important in auto-generalization. There are many simplifying methods most of which are practical and effective.Considering the principles of simplifying,six aspects have been proposed to estimate these methods which are area-difference,bend ratio,maximal-bendangle ratio,change-uptrend,result-coherence and self-intersection.The effect between Douglas-Peucker and Beam of Light has been compared by many experiments.At last,the corresponding step has been proposed to settle self-intersection.


Abstract : This progress report covers field work and laboratory analysis efforts for quantifying the environmental threat of radioactive waste released in the Arctic seas adjacent to the former Soviet Union and for studying the various transport mechanisms by which this radioactivity could effect populations of the U.S. and other countries bordering the Arctic. We obtained water, sediment, biological samples and oceanographic data from several cruises to the Kara Sea and adjacent waters and conducted detailed laboratory analyses of the samples for radionuclides and physical biological properties. In addition, we obtained water and sediment samples and conducted on site low level radionuclide analysis on the Angara, Yenisey River system which drains a major part of the Siberian industrial heartland and empties into the Kara Sea. We report on radionuclide concentrations, on radionuclide transport and scrubbing by sediments, on adsorption by suspended particles, on transport by surface and benthic boundary layer currents, on the effects of benthic and demersal organisms, on studies of long term monitoring in the Arctic and on an interlaboratory calibration for radionuclide analysis.


Spotify is a peer-assisted music streaming service that offers instant access to a vast music catalogue, and it has gained worldwide popularity in the past few years. Until now, little has been published about user behavior in such services. In this paper, we study the user behavior in Spotify by analyzing a massive dataset collected between 2010 and 2011. Firstly, we investigate the system dynamics including session arrival patterns, daily variations of session length, and playback arrival patterns. Secondly, we analyze the behavioral patterns of individual users on multiple devices and single devices, respectively. Our analysis reveals the patterns of users switching between multiple devices on successive sessions and the favorite times of day for Spotify users. We also show the correlations between both the length and the downtime of successive user sessions on single devices. Our findings not only deepen our understanding of user behavior in Spotify, but also shed light on user behavior in other music streaming services. We believe the results may also be used for building other types of services such as P2P social networks. In particular, our analysis of mobile user behavior provides valuable insights for developing systems on mobile platforms.


The artificial intelligence based learning model helps in identifying temporal material by processing linguistic terms that express time duration in code mixed data. The data available on social media contents are written in mixed script format and from this content temporal material content identification is a challenging task. The retrieval of temporal information and its corresponding time duration expression terms can be identified using artificial intelligence technique based neural learning model. The temporal retrieval and its time duration representation are widely used to present the opinions over the social media. The work described in the paper gives the comparative view of different techniques used in the area of transliteration. The rule framed approach is presented which accepts the roman form text as input and as per the defined rules the system is developed to give the temporal details words available in the sentence. The evaluation measures used here to validate the hypothesis is based on statistical measures along with HLSTM learning model. Further the result is validated using the voting technique that can choose appropriate Temporal label which are not identifies by the learning model. The applied neural learning approach increases the precision value.


Nowadays the Internet is used as an enormous source repository of information and it is accessible for everyone. This information is generated day-to-day by information sharing among the users. Customers or the users need this information for making their purchasing decision according to the reviews of other customers. As everyone wants to know the opinions from others that is why there is need of a system which can directly give the final opinions from this large collection of user reviews. The sentiment analysis is found to be very useful in various application areas like in news sector, healthcare industry, apparel industry, political elections, movie reviews and product review. The analysis of movie reviews has been emerged as a prominent area of research in this field. The proposed work applied a polarity feature based SVM technique to enhance the accuracy of the prediction of correct movie


The aqueous emulsion copolymerization of N,N′-methylenebis(acrylamide) (MBA) and an unsaturated polyester (UP) initiated with potassium peroxodisulfate was kinetically investigated at 50°C as a function of comonomer feed compositions. The reaction order with respect to the monomer concentration was found to be proportional to the UP monomer concentration at medium conversions and independent of the UP monomer concentration at low conversions. The high reaction order obtained from the dependence of the particle concentration on UP monomer concentration was attributed to the multifunctionality of UP monomer. At low conversions, an enrichment of the copolymer in UP structural units is observed. The polymerization was suggested to proceed in the aqueous phase, in the UP micelles and in the shell of the polymer particles.

Even though the efficiency of batch process is lower than that of continuous process, the batch process has been increased in the chemical process industry over past decade. The batch process is more suitable process to meet with the frequent changes of demands as the taste of consumers is changed within short period and life cycle of products is short- ened. The researches have been classified the chemical batch process into two types, multi-product batch process and multi- purpose batch process. Until now, the multi-purpose batch process had received little attention than multi-product batch pro- cess by researchers because of several characteristics which is hard to deal with such as irregularity of production path, existence of infeasible operation sequence and complexity of operation. Park and Jung(13-14) have studied the completion times algorithm and the optimal scheduling for multi-purpose batch process which have no recirculation products through the processing units. But in the case of real industry, for example the electronic semi-conductor industry, they usually have the products with recirculation path through the processing flow. So it can't be argued without appropriate considering of recirculation of products flow. In this paper we have developed the completion times algorithms of single line multi-pur- pose batch process including recirculation products under consideration of the non-zero set-up times and transfer times. We also developed the optimization method, genetic algorithm, for optimal scheduling of multi-purpose batch process includ- ing recirculation products. Finally the performance of the proposed algorithms was tested by several randomly generated examples and the Gantt chart results are presented. We used Genetic Algorithm for solving the scheduling problems and optimal solutions are also presented.


This study is entitled Analyzing the Semiotics by Roland Barthes in Making Video about Natural Disaster on the Citizen Journalism located in Bandung, West Java Province, Indonesia. This study aims to find out the practical ideology conducted by Citizen Journalism in making a video of the incident. Through this study, it is expected that people watching news do not guess the source of news taken by Citizen Journalism or professional journalists, because all the news informed by both are the same and no differences. The concepts and theories used in this study were the concept of mass communication, mass media, citizen journalism. In this study, the writer used semiotics analysis. From this study, there are some conclusions. First, in the video about natural tornado disaster occurring at SMPN 4 Rancaeke, it can explain how important to take a video of incidents and journalists have an important role in it. Second, various meanings that can arise in the interpretation of signs on the video about natural disasters which do not only reveal a single message about the ideology behind the myths presented. The major information obtained keeps using the ideology of capitalism as an ideology used by stakeholders concerned with the dissemination of information through the media. If it is connected to the practice of Citizen Journlism with the dissemination of information in the mass media, it is very relevant. Third, in analyzing the video of the incident, it was used Roland Barthes's semiotics in the video entittled "Tornado at SMPN 4 Rancaekek". The signs of tornado video incidents are directly visible (denotative) such as Tornado which then leaded to the interpretation that was constructed (conotative), i.e the event video practice conducted by Citizen Journalism to achieve the research objectives presented and qualitatively described.

The theory of cooperative games with vague cooperation is based on modelling fuzzy coalitions as fuzzy subsets of the set of all players who participate in the coalitions with some part of their "power". Here, we suggest an alternative approach assuming that coalitions are formed by relatively compact groups of individual players each of which represents a specific common interest. Each individual player may participate in several such groups and, as their member, in several coalitions. Our aim is to show that such an alternative model of fuzzy coalitions, in spite of its seemingly higher complexity, offers an interesting more sophisticated reflection of the structure of vague cooperation and of relations being in its background.

A Jet erosion tester is designed and assembling then used to study the relative erosion behavior of high density polyethylene (HDPE) with specific concentration of silica sand as an abrasive material, during varying impingement angles and specific size of abrasive particles. The water flow was turbulent. The test samples were mounted on sample holder and which has a provision to move in different angular positions to find out the erosion wear for different angles. The experiments were carried out using silica sand as erodent with a particle size range of (500-599) μm. Were used varying impact angles (90°, 60°, 45 ° and 30°) and solid abrasives of (2% wt.) concentrations have been used as fixed parameter for 20 hours. The concentration of slurries can vary from (2% to 50%) depending upon the type of slurry. Three samples were taken for each angle and the average was taken to obtain accurate results and was evaluated. The results which have been obtained shows that the erosion rate of (HDPE) was maximum at impact angle (45 ° ) and minimum at (30°).


During the grid fault, the DFIG low voltage ride-through guidelines require the wind farm to output the specified reactive current to support the electric grid voltage recovery, and the problem of the rotor overcurrent during fault will seriously damage the inverter. This paper proposed SVC to provide reactive power support and a control strategy to suppress the overcurrent, and builds a simulation model in MATLAB/Simulink.


This article identifies the predictors of child poverty rates at the state level before and after the adoption and implementation of the Personal Responsibility and Work Opportunity Reconciliation Act of 1996. The analysis shows that the most important state-level factors that influence child poverty rates are demographics, the health and viability of the state economy, and often the generosity, inclusiveness, and quality of state welfare programs. States with large numbers of black citizens, and those that score highest on infant mortality, teen births, births to unmarried women, children living with a parent without a high school degree, and children living with a single parent have the highest rates of child poverty. Child poverty rates are lowest in states that suffer less unemployment, and in wealthier states. States that score higher on per capita personal income, tax revenues, and taxable resources have lower child poverty rates. While specific "tough" welfare policies adopted by some states seem to have no impact on child poverty rates, we tested for the first time a sophisticated measure of the overall quality of state welfare programs. The analysis reveals that the global quality of a state's welfare programs is often an independent predictor of child poverty. States with the most generous, inclusive, and supportive welfare programs have done the best job of lowering and containing child poverty.


Composite materials offer huge upgrades over current accessible materials for various primary applications because of their fantastic mechanical qualities and moderately low thickness. Carbon filaments are most broadly utilized in vehicle, aviation, military and transportation of oil, gas and water applications. The specimen is prepared with varying stacking sequences (i.e., Carbon-Sisal- Carbon-Sisal [CSCS], Carbon-Sisal-Sisal-Carbon [CSSC] and Sisal-Carbon-Carbon- Sisal [SCCS]) and Carbon, Carbon, Carbon, Carbon (CCCC) and four carbon weight fraction (i.e., 2%, 4%, 6% and 8 %) with 2% of SiC. At the point when composites are used in water, oil and gas transportation, the lines are encountering high disintegration and burden. To learn about the impact of disintegration and burden, the malleable, flexural, influence, twofold shear and wear test are completed to comprehend the disintegration and conveying attributes of industrial applications. In this undertaking, the mechanical properties of composites on epoxy resin with sisal and carbon fiber have been considered. The result shows that the mechanical properties of carbon based samples shows that the better result as compared with other samples.


In order to improve the intelligent search capabilities of Internet financial customers, this paper proposes a search algorithm for Internet financial data. The proposed algorithm calculates the customers corresponding to the two selected financial platforms based on the candidate customer set selected from the seed dataset and combined with the restored social relationship. Moreover, it also calculates the similarity of each field between the pairs. Furthermore, this article proposes an entity customer classification model based on logistic regression. Through the SNC model, threshold propagation, and random propagation, the model is transformed into an algorithm that identifies the associated customers, eliminates redundant customers, and realizes associated user identification. Experimental results verify that pruning increases the accuracy of identifying related customers by 8.44%. The average sampling accuracy of the entire customer association model is 79%, the lowest accuracy is 40%, and the highest is 1. From the sampling results, the overall recognition effect of the model reaches the expected goal.

This kind of method is applied on evaluating alimentative type of Hunjiang reservoir, the result is the same as fuzzy comprehensive evaluation method.


To solve the carrier offset and the inherent IQ imbalance problem of the popular radio receiver architecture receiver named direct-conversion receiver, a joint calibration method with blind source separation based on whitening and non-linear decorrelation theory is proposed. Simulation results verified the feasibility and validity of the algorithm mentioned above upon dealing with the joint calibration problem of the IQ imbalance and carrier offset.


Typically, a photomultiplier tube (PMT) can be leveraged as the photon detector in the underwater optical wireless communication (UOWC) system to further extend the transmission distance, whose output electric signal can be generally classified into three regimes named discrete-pulse regime, transition regime, and continuous waveform regime according to various received optical power (ROP). In this paper, we experimentally demonstrate a low-power UOWC system that adopted a PMT as the receiver, and a detection method by taking the cumulative sum of the sampled values in a symbol duration is proposed and experimentally evaluated under different ROP and symbol rates. Experimental results show that the proposed detection method outperforms various statistics-based comparison benchmarks. Furthermore, the effectiveness of the proposed method in alleviating strong ambient radiation is experimentally verified.

AbstractBuilding on previous batch studies, this study further investigated the removal of dissolved organic P (DOP) using small (15 cm) columns with water treatment residual (WTR) and alum as two promising amendments to bioretention soil media (BSM). BSM modified with alum and WTR exhibited higher sorption capacity. Compared with unmodified BSM, significant improvements were observed for adenosine monophosphate (AMP), myo-inositol hexakisphosphate (IHP), and inorganic P (SRP) removal using 10% alum-modified WTR-amended BSM (WTR-BSM), by factors of 26, 7, and 150, respectively. The 10% alum-modified WTR-BSM reduced DOP levels<0.01  mg/L within 1 min of contact time, demonstrating more-rapid DOP sorption processes compared with unamended media. The oxalate ratio (OR), which is based on oxalate-extractable Al, Fe, and P, was employed to provide a criterion for BSM performance with respect to P sorption. Strong correlations (R2=0.92, 0.96, and 0.65 for AMP, IHP, and SRP, respectively) between the media OR an...


Most of the materials used for an airplane's front and rear fuselage skins are the 2024 Aluminum Alloy rolled plate material, which sometimes has the phenomenon of overgrowth of crystals when being stretched to take shape. In this experiment, the 2024 Aluminum Alloy Rolled Plate material in the thickness of 2.29 mm was applied to create the trial pieces whose initial statuses were the O material and the T4 material. We made the trial pieces undergo many kinds of experimental combinations such as different amounts of stretch and deformation, annealing, and solution heat treatment, so as to observe the changes of its sizes of crystal grains, in order to explore what factors result in the abnormal growth of 2024 Aluminum Alloy Rolled Plate during the process of stretch and deformation. In this experiment, Besides, through the observations via EBSD (Electron Back-Scatter Diffraction), we knew the microstructure-oriented {001} texture and structure of the trial pieces of O material and T4 material. When the trial pieces of O material received annealing and solution heat treatment after undergoing 5%-20% of stretch and deformation, compared with the gripping area, no occurrence of the growth of its crystal grains would appear when the amount of stretch and deformation was 5%; the maximum growth would appear when the amount of stretch and deformation was 10%, and the vertical and transverse sizes of the crystal grains were respectively 4.3 times and 3.1 times greater than that of the gripping area. Also, the appearance of the crystal grains after the growth was non-equiaxed crystal. When the amount of stretch and deformation was 15% or 20%, the crystal grains would shrink contrarily and get close to the size of the crystal grains in the gripping area. Therefore, if we make the O material of the 2024 Aluminum Alloy Rolled Plate avoid 10% of the amount of stretch and deformation, we can ward off the overgrowth of crystals. In addition, through the Stretch Stress Strain Diagram, we knew that the stretch stress necessary to be imposed on the trial piece of T4 material was about 2 times greater than that on the O material. Besides, from the observations on the trial piece of T4. material with 10% of stretch and deformation via TEM(Transmission Electron Microscopy), we found that high-density dislocations exist in the aluminum base. However, the experiment results showed that the sizes and shapes of the T4 material's crystal grains nearly have no changes after the T4 material had undergone 5%-20% of stretch and deformation and then received annealing and solution heat treatment. Furthermore, after the T4 material and the O material underwent 10% of stretch and deformation, their neighboring crystal grains would deform in the two closer crystal axial directions each other. Through the observations on the trial pieces via TEM, the T4 material had plastic deformation centering on the crystal boundary, while the O material had plastic deformation both around the crystal boundary and within the crystal grains. Judging from deduction, we consider: When the plastic deformation of a crystal grain spreads all over the crystal grain, such a plastic deformation can be the thrust of the crystal grain to adjust its crystal axial direction. To sum up the observation results mentioned above, when the O material receives annealing and solution heat treatment after undergoing 10% of stretch and deformation, a certain mechanism will appear, in which, There exists a mechanism including adjustions of neighboring grain axis, the driving force of the strain energy as deformation in room temperatureand surface energy decrease of grain boundaries. It leads to the dislocations by the grain boundaries offset mutually and eliminate by rearrangment.The grains by the side of dislocations combine to grow.


Report presenting a low-speed wind tunnel investigation of an exploratory nature in order to determine a satisfactory location for a spoiler lateral-control device for a sweptback wing. The semispan wing used for the tests had 42 degrees sweepback referred to the wing leading edge and an aspect ratio of 4.01. The best location appeared to be near the trailing edge of the wing, slightly inboard from the wing tip, and skewed with reference to the wing so as to be perpendicular to the free-stream air flow.


Any cell of a network experiences two types of call arrival; new originating call, and handoff call from surrounding cells. If the number of busy users around a cell is finite with an average value of N, then rest of the radio resources of the network can be assigned to support handoff calls. So, for handoff calls, the traffic case resembles a network with limited user traffic (PCT-II), where as rest of the radio resources handle unlimited user traffic (PCT-I). In this paper, a mixed traffic model (combination of PCT-I and PCT-II) has been considered to evaluate different traffic parameters like, probability state and call blocking of a cellular network. For analysis, here, two-dimensional state transition diagram as well as tabular method is considered.


The present acoustic experiment studies the acquisition of Standard Chinese vowels by native speakers of Uyghur. The results indicate that in identifying the 7 vowels of Standard Chinese produced by the native Han Chinese speakers, Uyghur subjects with high Chinese proficiency perform better both in accuracy and reaction time than Uyghur subjects with low Chinese proficiency, and all the Uyghur subjects are not good in perceiving vowels //, /i/ and //. The results of the experiment support the Speech Learning Model and the Perceptual Assimilation Model. In addition, it shows that the second language speech acquisition is restricted by the first language phonological system.


Bupropion‐induced psychosis has been observed until now primarily in patients with a psychiatric history who received bupropion as an anti‐depressant. A case of bupropion‐induced psychotic symptoms is reported for a patient who took bupropion as a smoking cessation treatment and who had no previous psychiatric history. The course of the symptomatology was comparable to those of previous reports on patients receiving bupropion as an anti‐depressant.

The information contained in any given experimental time series can be utilized more exhaustively when transition probabilities between states rather than state probabilities alone are studied. Using advanced techniques of time series analysis, it is shown that deviations from dynamical randomness indicate evidence for unexpected temporal correlation features in selected data sets taken from a mind-matter experiment conducted at Freiburg (Germany). The techniques of analysis and a proper error estimation are briefly described, and some preliminary first results are presented. They encourage further inquiry into processual aspects of deviations from randomness in addition to more straightforward analyses of state probabilities.

In the first half of the eleventh century, a group of scholars in southwest India did something new. They began composing systematic texts about everyday life in a register of language sometimes called New Kannada. While looking back toward earlier texts composed in Sanskrit – and even translating portions of them – these scholars centered their poetic ability and their personal experiences as opposed to prior authoritative texts. They described themselves as authoring "worldly sciences" that were "useful to the people of the world," and they provided extensive reflections on the systematics of knowledge. Epistemic, linguistic, and political concerns were significantly renegotiated in this moment as local context was turned into a virtue for the production of technical treatises. This article uses this moment to interrogate recent discussions of useful knowledge and vernacular science. Usefulness can mean different things at different times and vernacular sciences change according to their language. This article argues for a usage of both terms that is more attuned to historical particulars. A history of useful knowledge from a place that now appears under the double effacement of the non-modern and non-West offers an opportunity to think through central concepts of the history of science without relying on economic or utilitarian discourses. This paper presents one possible example of what a more global history of useful knowledge might look like.


Foam injection molding is a processing technology particularly interesting for biodegradable polymers, which present a very narrow processing window, with the suitable processing temperatures close to the degradation conditions. The addition of a physical blowing agent, besides decreasing the final part weight, reduces both the viscosity and the glass transition temperature of the polymer melt, allowing the processability of these materials at lower temperatures. In this work, structural foams of polylactic acid with nitrogen as physical blowing agent were obtained by foam injection molding. In particular, the effects of back pressure, namely the pressure imposed inside of the cylinder when the screw is returning back to prepare a new amount of material to be injected, and of the injection flow rate on foaming and mechanical properties of the molded parts was assessed. It was found that the samples molded adopting a higher injection flow rate are shorter than those injected at lower flow rate, and this result was ascribed to the large compressibility of the injected shot. As far as the mechanical properties of the foamed parts, it was found that the modulus decreases with decreasing density. However, the density reduction is not the only significant parameter, but also the morphology of the foams should be taken into account in order to justify the differences between tensile and flexural modulus.


Unsaturated fluid flow in thin porous media depends on hydraulic properties, such as the capillary pressure, P c , as a function of saturation, S. We measured this relationship for two different types of compressible thin hydrophilic fibrous layers under varying conditions. Among other factors, we changed the number of layers and the overburden pressure (i.e. the confined solid pressure applied on top of the sample) imposed on one layer or a stack of layers. Applying an overburden pressure drastically affected the P c ( S ) curves. However, increasing the number of fibrous layers had little impact on the capillary pressure–saturation curves. We also investigated the effect of multiple imbibition–drainage cycles on the P c ( S ) data. Measured data points were used to find general expressions for the P c ( S ) relationships of compressible thin porous media. Existing quasi-empirical correlations used in vadose zone hydrology, notably expressions by van Genuchten (Van Genuchten MTh. A closed-form equation for predicting the hydraulic conductivity of unsaturated soils. Soil Sci Soc Am J 1980; 44: 892-898) and Durner (Durner W. Hydraulic conductivity estimation for soils with heterogeneous pore structure. Water Resour Res 1994; 32: 211–223) for single- and dual-porosity media, respectively, were employed to fit the measured data points.


The paper aims to describe the potential in building up the economic base of agricultural cooperation development in the Kyrgyz Republic, to propose an organisational and economic mechanism of cooperative relations in the Kyrgyz Republic, taking into account the complex development of agricultural production, logistics infrastructure and cooperation. Cooperation is viewed as an efficient economic mechanism to integrate small agricultural producers into the commodity distribution systems in the domestic and international agricultural food markets. Building on a review of sources describing the potential of cooperation in the modern environment, analyses of the agrarian structure and assessments of the economic base of cooperation, the paper proposes an organisational structure to navigate through the development of an effective agrarian structure, logistics infrastructure and cooperation in the Kyrgyz Republic.The paper is based on the materials from international development organisations, the National Statistical Committee of the Kyrgyz Republic and the findings of some researchers. The makings of the paper may be helpful summarising the international practice of development of cooperative relations, enhancement of institutional conditions and public policies of support of cooperation in the Kyrgyz Republic and should be of interest for a wide research audience in the area of agricultural cooperation.


Photonic crystal fibres (PCFs) offer new possibilities of realizing highly birefringent fibres due to a higher intrinsic index contrast compared to conventional fibres. In this paper, we analyse theoretically the modal properties of a kind of polarization-maintaining PCF, namely the elliptical hole photonic crystal fibre (EHPCF) with a central small elliptical hole introduced in the core region. We demonstrate the possibility of achieving large birefringence with zero walk-off in the single-mode regime. This PCF also exhibits unusual dispersion properties. Several hundred nanometres of ultra broadband flattened dispersion near the wavelength 1.55μm is achieved in this EHPCF with a central small hole of dc=0.4Λ.


To the Editor: Early-onset schizophrenia (EOS), by definition, has an onset before age of 18 years. It is notorious for heavy genetic load, soft neurologic signs, male preponderance, insidious onset, mainly negative and cognitive domains presentation, gross functional impairment, poor prognostication, and generally poor antipsychotic response. Kasoff et al1 have showed an even greater differential efficacy of clozapine in EOS compared with adult counterparts spanning different symptom domains. This might be related to clozapine's unique composite mechanism of action (Table 1). Nonetheless, clozapine is clearly underused in child psychiatry. Use is typically plagued with a host of serious side effects. Here, we are reporting on an adolescent case with EOS that has favourably and ultimately responded to clozapine but with problematic weight gain and sialorrhea. We embarked on a trial of add-on atomoxetine (ATX) to address cognitive facets. ATX surprisingly helped with both cognitive and negative domains, mitigated metabolic parameters, and successfully tacked sialorrhea as well. This might open new venues for such refractory cases. A 14-year-old Kuwaiti male youngster was casualty petitioned by his kindred for disorganized behaviour coupled with serious scholastic drop with 1-year incipient onset of social withdrawal, barricading himself from others, neglected self-hygiene, fitful sleep, vague and digressive speech, and scholastic unattainment. School reported escalating hostile behaviour recently, unkempt dishevelled appearance, and academic failure. At home, he began to exhibit total insomnia, pervasive suspiciousness, and unfounded inordinate giggling. At times, he was noticed to be muttering under breath. This ran a progressively deteriorating course and reached a nadir when the patient, in jactitation, gripped a knife to "protect" himself from those "taping him on cameras" as he put it. The patient has a schizophrenic home-bound father who is currently maintained on paliperidone. He has unremarkable developmental trajectories, apart from occasional motor tics as mother has reported. He was hospitalized for safety concerns. Full work-up for a "first-episode psychosis" was undertaken, including baseline laboratory investigations, thyroid functions test, B12, prolactin, toxicology screen, electrocardiogram, electroencephalogram, and brain scan, all with negative yield. The patient has failed adequate sequential trials on aripiprazole, olanzapine, and paliperidone monotherapies, despite ensured compliance, in a private psychiatric clinic. He had put on much weight, though. Clozapine was then proposed and psychoeducation with bibliotherapy was provided. Clozapine was titrated up to 300 mg/d over 4 weeks with a cognitive-behavioural therapy monitoring protocol. Tangible improvement was noticed chiefly in the positive and aggressive domains. He was discharged to follow-up at outpatient clinic. Despite symptomatic remission, weight gain together with negative and cognitive domains remained very much impairing both socially and academically. Sialorrhea was dose-limiting when we attempted to push up clozapine dosage and meanwhile too bothersome side effect both to the patient and to the caregivers. ATX was suggested for cognitive concomitants and parents' consent obtained. Digit symbol substitution test (DSST) was administered beforehand (and read 35). It was titrated up to 80 mg/d, over 4 weeks (weight of 70 kg). Better interpersonal socialization was noted. Negative Table 1. Pharmacologic portfolio of clozapine.


This study aims to determine the improvement of student learning outcomes through the online class recitation learning model during the covid-19 pandemic, on the learning process of class X1 students of the Accounting Department at SMK Negeri 1 Tompaso Baru Minahasa, totaling 14 students. The online classroom research method used is in the form of CAR (Classroom Action Research) which refers to classroom action research. In terms of treatment, learning is given that applies an online class recitation learning model.
From the results of the analysis obtained by researchers on accounting subjects with service company accounting cycle material with the stages: Recording transactions/documents into general journals (General Entries) and posting from general journals to general ledgers (General Ledger), there is an increase in student learning outcomes.  This increase can be seen from the percentage of student learning completeness individually and classically. This increase can be seen from the percentage of student learning completeness individually and classically. At the pre-cycle stage or before the implementation of the action, the average value of the class was 63.92 with the percentage of classical learning completeness only 35%. In the first cycle, it reached an average of 71.78 with a classical mastery level of 64.28%. While the learning outcomes in the second cycle reached an average of 77.85 with the classical learning completeness level reaching 92.85%. Likewise with student learning activities at every face-to-face online class. Student activity at the 1st meeting only reached a percentage of 56.25% with high criteria. At the second meeting it reached a percentage of 72.76% with high criteria, and at the third meeting it reached a percentage of 83.92% with very high criteria. Thus, student learning activities and student learning completeness in online classes during the COVID-19 pandemic increase by using the online class recitation learning model. With learning outcomes reaching 92.85% above the minimum learning completeness.


The presence of thiosalts in mining wastewaters is an environmental issue due to the resulting pH depression as these species degrade with time. Despite research in the area, reaction kinetics of thiosalt species under different pH and temperature conditions are not fully understood, especially in conditions common in receiving ponds. As a result, it is difficult to design ponds or develop treatment technologies to treat these compounds. Several studies have dealt with the reaction kinetics of major thiosalt species (thiosulfate, trithionate, tetrathionate) under various pH and temperature conditions. However, further research is required to better understand the fundamental behaviors of thiosalt species and identify probable reaction paths in temperatures below 30°C, pH range between 2 and 9 and in the presence of reagents. -- The overall objectives of this work have been to study the behavior of thiosalts in mining wastewaters and develop a model of their behavior under the conditions studied that includes pH and temperature as independent variables. The study is divided in four parts: the first part is a summary of relevant information in terms of generation and kinetics of thiosalts, analytical methods for measuring their concentrations, and treatment of thiosalt wastes. Despite extensive research in the area, generation and kinetic information of thiosalt species under different pH and temperature conditions is not fully understood, especially under the range of conditions likely to be encountered in receiving ponds. -- The second part of the study analyzes the behavior of thiosulfate, trithionate and tetrathionate and provides with mathematical models for their behavior as pure species under the specified conditions. The third part of the study consists of the analysis of the thiosalt behavior in mixtures following a decoupling approach; this analysis provided with additional information for the proposal of global reaction pathways for the species. Finally, the last chapter provides preliminary results from kinetic experiments with selected reagents, results from equilibrium simulations and an analysis of future work required to improve the understanding of thiosalt reactions, improve treatment efficiency and reduce the environmental impact of acid mine drainage.


Monitoring methane (CH) concentration is essential in many industrial and environmental applications. Hollow-core photonic bandgap fibers (HC-PBF) have emerged as a promising technology in the field of gas sensing. The long interaction path lengths achievable with these fibers are especially advantageous for the detection of weakly absorbing regions of methane. In this paper, a novel methane sensor based on HC-PBF capable of measuring CH4 concentrations down to 0.1% in air has been demonstrated.


OBJECTIVE: To evaluate the effect of cerebral reperfusion related to clinical outcomes after endovascular treatment in acute ischemic stroke. BACKGROUND: In a number of clinical trials, case series and comparative nonrandomized studies reported in the last decade, improvement over time of recanalization rate was not paralleled by a consistent amelioration of clinical outcomes. We hypothesized that, given case selection, these studies may not reflect real world variability of ischemic stroke. DESIGN/METHODS: The Italian Registry of Endovascular Treatment in Acute Stroke (IRETAS) consecutively records patients treated with intra-arterial thrombolysis or trombectomy in 25 tertiary stroke centres . We studied successful reperfusion, defined as Thrombolysis in Cerebral Infarction (TICI) score 2b-3, as independent predictor of good functional outcome (3 months modified Rankin scale RESULTS: From 2008 to 2012, 748 patients were registered. Outcome data were complete for 527 (70.5%) patients . Outcome predictors were similarly prevalent comparing patients who were included to those excluded from the analysis. Median age of the 527 patients was 68 (54-75) years; 56.5% were males. Baseline median NIHSS was 18 (13-22). s-ICH occurs in 51 (9.7%) patients, procedural adverse events in 25 (4.7%) patients. Complete reperfusion was achieved in 303 (57.5%) patients. Two hundred twenty five (42.7%) patients had a good functional outcome. Death rate was 24.9% After adjusting for age, gender, baseline NIHSS, time from onset to groin puncture, site of occlusion, treatment modality, successful reperfusion strongly predicted good functional outcome (OR 1.92, 95%CI, 1.60-2.31). CONCLUSIONS: In a real word practice scenario good functional outcome was strongly associated with successful reperfusion.

Marine microorganisms such as bacteria and fungi inhabit virtually any environment in the sea, and they are rich sources of chemically and biologically diverse compounds. In our search for bioactive compounds in marine microorganisms, two new halogenated alkenoates, methyl 2,4dibromo-5-oxo-2-decenoate (1) and methyl 2,4-dibromo-5oxo-3-decenoate (2), and the known sesquiterpenediol, cycloneroidol (3), were isolated from the broth of an unidentified fungus, which was separated from the surface of the marine red alga Gracillaria verrucosa collected at Jinha, Ulsan in 2002.


We reported on characterization of 2-terminal and 3-terminal InGaP/GaAs heterojunction phototransistors (HPTs). For a current-bias 3T-HPT, an independent current flowing into or out of base electrode is employed. Addition of biased current pushes HBT's operating point to a higher current level where the current gain is larger. It is found that the optical gain increases from 28.4 for a 2T-HPT to 34 for a 3T-HPT with a biased current of 10 μA. Although an independent voltage source also pushes HBT's operating point to a higher current level, p-i-n photocurrent generated within the B-C region contributes very few to final collector photocurrent for a voltage-bias 3T-HPT. The optical gain obtained from voltage-bias 3T-HPT is as small as 0.8 ∼ 1.6


In this work, we studied the effects of electrochemical oxidation treatments of carbon fibers (CFs) on interfacial adhesion between CF and epoxy resin with various current densities. The surface morphologies and properties of the CFs before and after electrochemical-oxidation-treatment were characterized using field emission scanning electron microscopy, atomic force microscopy, Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, and single-fiber contact angle. The mechanical interfacial shear strength of the CFs/epoxy matrix composites was investigated by using a micro-bond method. From the results, electrochemical oxidation treatment introduced oxygen functional groups and increased roughness on the fiber surface. The mechanical interfacial adhesion strength also showed higher values than that of an untreated CF-reinforced composite.


This paper notes that whilst there are some problematic factors that teachers need to consider when contemplating introducing the works of William Shakespeare into Japanese tertiary reading classes, this need not prevent them from doing so. Indeed, despite possessing antiquated language and idioms that our students may not be familiar with, Shakespeare's plays contain poetic ideas and themes that are universal to the human experience. This study recommends three approaches that have been utilized with sophomore university English students to teach key ideas in the plays Macbeth, Romeo and Juliet, and Hamlet. It argues that, when they are explicated, realizing these ideas can equip our students with insights additional to language or cultural acquisition, because such literature contains ideas that are part of the shared human condition.


Abstract Conservative terrorism scholars have made the claim that the media have become a propaganda tool for terrorists and sympathetically portray terrorist activities. This article provides quantitative and qualitative data from Time magazine in 1986 suggesting that this view is mistaken. News production is treated as a social process that both informs and obscures, rather than as a neutral process that simply provides 'objective' facts. The results of the investigation reveal seven ways in which ideology is manifested in the terrorism news: semantics, language, headlines, social and historical context, treatment of objectives, trivialization, and amplification of violence. The ideological uniformity and lack of diversity apparent in terrorism news suggests that this kind of treatment results in a lack of understanding of the media/terrorism relationship and serves to support conservative views about the nature of terrorism and appropriate responses to it.


ABSTRACT The main goal of this study was to investigate parent-adolescent value similarities in a Romanian sample by taking the relative importance of mothers' and of fathers' parenting style into account. More abstract values were studied here, namely individualism and collectivism as well as independence and interdependence. Some theoretical approaches argue for differential effects of fathers and mothers on children's values, but the results are inconsistent. Dominance Analysis (Azen & Budescu, 2003) was used as methodological procedure, a strategy that allows identifying the most consistent predictor model across all possible subset models within regression analysis. Standardized separate interviews were conducted with mothers and fathers whereas the adolescents filled out the questionnaire in the classrooms (N = 100 families). Parent-adolescent value similarities were found for collectivism only. Parenting contributes stronger to adolescents' values (collectivism and interdependence) than parental values themselves. Overall, the contributions of fathers' parenting variables dominated the contributions of mothers to both daughters' and sons' values, providing thus weak evidence for the gender role models of socialization theory. KEYWORDS: similarities, Romania, parenting, dominance analysis INTRODUCTION Value formation is an important task during adolescence (Erikson, 1968; Rohan & Zanna, 1996). Recent approaches attribute children, especially adolescents, an active role in shaping their own value orientations (Grusec & Goodnow, 1994). However, the family remains the primary context for the socialization of values (Smith, 1983). The main goal of the present study is to investigate parent- adolescent similarities across different values (individualism, collectivism, independent and interdependent self-construal) in Romania examining the influence of parents' and adolescents' gender. Parents influence the children's values and self-construal not only by communicating to them these aspects, but also by organizing their lives in ways that are conducive to the appreciation of certain values over others. For instance, child-rearing practices exemplify parental values in action, and presumably, they have an indirect influence on children's values (Kohn, 1983; Roest, 2009). Therefore, a second goal is to analyze the importance of parenting style for adolescents' values and self-construal. Fathers are often neglected in value socialization studies, and those that included both parents show divergent results. Such inconsistencies in results can often be attributed to methodological weaknesses, with maternal and paternal predictors moderately to strongly correlated, thus leading to multicollinearity when predicting their child's characteristics. A third goal of this paper is to analyze the predictive strength of parental characteristics in specific dyads of mother/fatherdaughter/ son by using dominance analysis (Budescu, 1993). This strategy allows identifying the most consistent predictor model across all possible subset models within regression analyses. Dominance analysis considers mothers' and fathers' overlapping predictive abilities in determining their relative importance and helps to isolate and identify fathers' and mothers' contributions to their children's development. Most of the studies were conducted in Western countries with relatively stable socio-economic and cultural conditions. The current study was carried out in Romania, a country that faced enormous changes after the collapse of communism in 1989. It is assumed that changes in political structures, institutions, material resources and opportunity structures (at the macrosystem level) produce changes in the individual and the relations between the individuals. The study focuses on within-country comparisons with particular attention given to gender-specific dyads (gender of the parent and of the adolescent). …


The body has become a major focus of attention—both theoretically and politically—over the past twenty years. In much of this literature it is presumed that the body is some kind of social construct at the same time as it is a locus and a measure of both the material and the social world we inhabit. The author situates this idea against the background of Marx's representations—too often by-passed in recent literature—in order to show how Marx's concept of variable capital contains a theory of body formation under capitalism at the same time as it lays the groundwork for understanding how political persons act as moral agents to try to change the conditions under which laboring occurs. The struggle for a living wage in Baltimore is then used as a concrete example of how this form of body politics operates under contemporary conditions, illustrating how the body that is to be the measure of all things is itself a site of political-economic contestation over the very forces that create it.


Analysis of it's own revenue figures over the past years can provide great insight for the management of a company. Nevertheless, this approach has its shortcomings. Regardless of the information about its own revenue figures and growth or decline trends in the past, management of a company is lacking a broader view of the current competitors' activity and presence on the market. To understand how other competitors are performing and what are the reasons for the growth or decline, managers need information for the whole market. With this information in hand, position and underlying reasons for the growth or decline can be deduced. The annual reports of companies provide relevant and faithful representation of the financial information. Annual reports are published on average 6-7 months after the end of the calendar year. Since the published documents provide figures for a last year it is a good source for the analysis of the past time. To forecast the revenues for the next year, financial figures published in those reports are not enough. However, in addition to the figures, the annual report contains the management report part. For the particular example of the revenue forecasting, the textual sources of information have remained untapped so far. Since the point of view in competitor analysis is outside of the monitored company, one doesn't have internal information like sales figures or pricing strategy. For the forecast of annual revenue growth rate, the standard method is simple to average the revenue figures of the previous 3 years. The shortcoming of this approach is that output of the model is very inaccurate. The other useful information would be plans, strategy and management's attitude towards the future economic and political status of the country. The assumption is that relevant soft facts are taken into consideration when management reports are written. By mining the sentiment we should be able to partly grasp those soft facts. This work proposes to mine the sentiment from the annual management reports. In the reports, the particularly interesting section is the Outlook section in which the view of the near future is expressed. Using the techniques of sentiment mining, we analyse correlation of the different opinion measures in the Outlook sections and compare it to the corresponding historical revenue figures. Correlation coefficients between revenues and sentiment scores are calculated. Results are interpreted by the domain experts and conclusions are made. This thesis is done in cooperation with Siemens AG Austria and


In order to the torque control, the indirect flux control was performed by controlling the ratio of elf, and the q-axis flux was estimated by the slip command and q-axis current in the rotor circuits. Also, the frequency was controlled to keep on the q-axis flux to be zero, and the constant torque characteristics could be obtained by generation the preset torque
In the induction motor driven by voltage source inverter with the constant voltage and frequency, the speed variation is expressed as a slip. So, the speed control can be achieved by slip
compensation. The slip was calculated with a q-flux current filtered by first-order filter, and, as the result, the error problem which may occur in current detection Was eliminated.


The objective of present study was to evaluate the efficacy of pleural fluid alkaline phosphatase and its ratio to serum levels to classify pleural fluids. A total of 80 patients were divided in transudates and exudates on the basis of extensive clinical, radiological and biochemical evaluation. The efficacy of pleural fluid alkaline phosphatase (P ALP) and pleural fluid / serum alkaline phosphatase ratio (P/S ALP) assessment along with that of Light's criteria to accurately classify transudates and exudates were analyzed. Up to 89% transudates misclassified by Light's criteria were correctly classified by pleural fluid alkaline phosphatase (P ALP) and pleural fluid/serum alkaline phosphatase ratio (P/S ALP) evaluation. Similarly 92% exudates misclassified by Light's criteria were correctly classified by pleural fluid alkaline phosphatase (P ALP) and pleural fluid/serum alkaline phosphatase ratio (P/S ALP) evaluation. By applying a cut off value of 40.0 IU for P ALP, a sensitivity of 85% and specificity of 75% was found. For P/S ALP, applying a cut off value of 0.25 a sensitivity of 85% and specificity of 80% was found. Both P ALP and P/S ALP had a PPV of 92%. However, their respective NPV were 63% and 70%.


Medulloblastoma (MB) is a common primary tumor of the central nervous system diagnosed in pediatric patients. Survivors of MB are frequently accompanied by severe side effects, thus it is urgent to explore novel therapeutic target. First of all, the level of antisense non‐coding RNA in the INK4 locus (ANRIL) in normal cerebellum and DAOY cells were evaluated. Then, the effect of ANRIL on DAOY cell proliferation, migration, and apoptosis were tested. Then, qRT‐PCR was performed to explore whether ANRIL acted as a sponge of miR‐323. The effects of miR‐323 inhibition on ANRIL silence‐induced alterations of cell proliferation, migration, and apoptosis were estimated. Predicted by TargetScan, the possible target gene of miR‐323 was screened, followed by validation with luciferase assay. The abnormally expressed BRI3 on cell proliferation, migration, apoptosis, and signaling pathways were all evaluated. ANRIL was up‐regulated in MB and its silence significantly lowered cell viability and migration but promoted cell apoptosis. ANRIL acted as a sponge of miR‐323 and its silence functioned through up‐regulating miR‐323. BRI3 and CDK6 were target genes of miR‐323 and the effect of BRI3 on DAOY cells was the same as ANRIL. Moreover, ANRIL suppression could reduce phosphorylated levels of p38 MAPK, ERK and AKT, and inhibit Wnt signaling pathway through positively regulating BRI3. ANRIL inhibition repressed cell proliferation and migration but promoted cell apoptosis through miR‐323‐mediated regulation of BRI3, which could activate p38 MAPK, ERK, and AKT as well as Wnt signaling pathway.

cathode powders with fine size have been synthesized by spray pyrolysis from the spray solution with citric acid and ethylene glycol. The as-prepared powders with spherical shape, porous structure and micron size turned into powders with micron size and regular morphology after post-treatment at . The initial discharge capacities of the powders changed from 199 to 171mAh/g when the concentrations of the citric acid and ethylene glycol added to the spray solutions were changed from 0 to 1 M. The maximum initial discharge capacity of the powders obtained from the spray solution with citric acid and ethylene glycol was 198 mAh/g when the lithium component added to the spray solution was 6 mol% excess of the stoichiometric amount. The discharge capacities of the fine-sized powders dropped from 198 to 163 mAh/g by the 30 th cycle at a current density of 0.1 C.


Static shear loading tests on single full-height walls, hanging walls and window-back walls with dry-mud-panels were conducted. And then, push-over analysis of combinations of the walls was performed, it was found that summation of shear forces of the single walls is higher than the shear force of combined analysis model except for the range of relatively large deformation. Consequently, to evaluate shear resistant performance of traditional wooden building with dry-mud panel, summation of shear forces of the single walls was found to be adequate

The increased demand for large size forgings has led to developments and innovations of heavy-duty forging manipulators. Besides the huge carrying capacity, forging manipulators should possess robot features, such as force perception, delicacy, and flexibility. The aim of this work is to develop a practical compliance control method for hydraulic forging manipulators. A hybrid force–position control method is proposed and performed on a novel serial–parallel forging manipulator designed by the author's institute. A specific study is carried on a hybrid pressure–position control system. The simulated and experimental results show the control method is feasible. The experiment on hybrid control is executed on a programmable logic controller considering industrial applications.

How to eliminate health disparity to ensure health equity is one of major issues that are handled across the world. The purpose of this study was to examine any possible differences in self-rated oral health state according to socioeconomic status and the relationship between the two based on the data of the 5th National Health & Nutrition Examination Survey of 2010~2012. As for differences in self-rated oral health state according to sociodemographic characteristics, the women considered themselves to be in poorer oral health than the men. The older respondents found themselves to be in poorer oral health, and there was a tendency that the respondents who were less educated and whose household income was smaller rated their own health as worse. When a logistic regression analysis was made to determine influential factors for self-rated oral health status, the women perceived they were in better oral health than the men did, and the better-educated respondents were more likely to consider themselves healthier. Concerning disparities in self-rated health state according to income level, there were broader differences in that regard according to an increase of income. The findings of the study illustrated that there was oral health inequity according to social stratum. It's required to make a nationwide effort to promote national oral health, and appropriate support should especially be provided for disadvantaged people at the same time in order to get rid of the gap in oral health among different social classes, as there is a yawning gap between them and the other classes.


The term 'density of dwellings' used by geographers is conceptually different to the term 'probability density of dwellings' used by statisticians. In Cartesian coordinates the numerical values only differ by a scaling constant, but in polar coordinates this is not the case. To help clear up the resulting confusion, this paper attempts to show the relation between the two concepts.


The effect of polarizing mngnetic field intensity on the nuclear resonant absorption was studied by varying the field strength at a 1-mc Co/sup 57/ source from 0 to 1000 gauss while keeping the absorber between the poles of a magnet having a fixed field of 800 gauss. The rates of resonance absorption change with field intensity were greatest in the region of 300 to 1000 gauss, and the% nuclear resonant absorption for 1000-gauss fields was 8.5 and 26% for perpendicular and parallel fields, respectively, as compared with 15% for no fields. Other absorption measurements for Co/sup 57/ sources are also reported. Calculations on the use of nuclear resonant absorption to measure gravitational fields and altitudes were made which indicates that this application is not promising. (D.L.C.)


The inflammatory bowel disease (IBD) includes Crohn′s disease and ulcerative colitis. The incidence of IBD is rising on a yearly basis in China, followed by an increased number of patients who suffer from the complications. Medicines and surgical treatment are the major maneuver in the management of patients with IBD. Recently, mesenchymal stromal cells MSCs were found to exert powerful immunomodulatory effects, which suggest the possibility of an alternative treatment for patients with IBD. In this article, the most recent literatures in this field will be reviewed combining with our own clinical experiences. The functions of MSCs, the pathogenesis of IBD and research situation of MSCs therapy for patients with IBD will be discussed.

We study a growing biological tissue as an open biphasic mixture with mass exchange between phases. The solid phase is identifled with the matrix of a porous medium, while the ∞uid phase is comprised of water, together with all the dissolved chemical substances coexisting in the pore space. We assume that chemical substances evolve according to transport mechanisms determined by kinematic and constitutive relations, and we propose to consider growth as a process able to in∞uence transport by continuously varying the thermo-mechanic state of the tissue. By focussing on the case of anisotropic growth, we show that such an in∞uence occurs through a continuous rearrangement of the tissue material symmetries. In order to illustrate this interaction, we restrict ourselves to difiusiondominated transport, and we assume that the time-scales associated with growth and the transport process of interest are largely separated. This allows for performing an asymptotic analysis of the \fleld equations" of the system. In this framework, we provide a formal solution of the transport equation in terms of its associated Green's function, and we show how the macroscopic concentration of a given chemical substance is \modulated" by anisotropic growth.
