In view of the continuously rising environmental problems and the increasing energy demand worldwide in general, the utilization of sustainable renewable energy and treatment methods have become a scientific and industrial move in the last few years. One of the most important energy sources, biomass constitute a precious source. The sustainable conversion of biomass products and the use of different agricultural and forestry-derived residues can play an important role in reducing pollution in many phases. Date palm Phoenix dactylifera L. is one of the most important fruit trees that is found in tropical, sub-tropical and arid regions of the world precisely those stretching from North Africa to the Middle East. There are about 120 million date palm trees in the world where each date tree generates around 20 kilograms of dry leaves annually while date pits account for almost 10% of date fruits. A varied range of physicochemical, biochemical and thermal technologies has been applied for sustainable application of date palm biomass. The present review elucidates the possible use of date palm waste and the efforts so far made in both producing biochar and its use in different treatment processes. The review also defines the future required solutions for the date palm waste problems.


This paper seek to evaluate the application potential and accuracy evaluation of CBERS-02B high resolution(Pan) data.Taking Xixiang County of Shaanxi Province as a test area,radiometric and color enhancement is performed to HR image;then the HR image was fused with the CCD images based on five algorithms, and image qualities are evaluated between original images and fused images in terms of qualitative and quantitative aspects.Finally,land-use categories were extracted and classification accuracy was evaluated based on the two datasets.The results show that land-use classification accuracy is improved greatly by fusion of 02B high resolution data and CCD data,and Brovey algorithm is best for keeping the spatial textures and spectral characteristics of images among five algorithms.HR image should be applied widely in resources investigations and ecological environment monitoring.


Any political debate about Uganda tends to become polarised very quickly. Champions of the prevailing economic orthodoxy speak of the past 30 years as an almost unqualified development success. Critics of the establishment point to the absence of tangible benefits for a broad range of the population. These positions came into sharp focus in 2018 when the People Power movement gained momentum following the international outcry triggered by the abduction and torture of its de facto leader, R. Kyagulanyi, MP.


THE ANALYSIS OF THE ASPECT OF RACISM IN THE MULATTO SOCIAL LIFE FROM CHARACTER EMMA LOU AS REFLECTED IN WALLACE THURMAN`S NOVEL IN "THE BLACKER THE BERRY"


Reusing the original data of enterprise,essentially,collecting them,is very difficult because they are stored in different ap-plication systems and their structures are heterogeneous.An approach of data collection based on rule is proposed,in which the data collection process is looked as two cases: Common case and special case.Common case is abstracted into various rules,and then rule set is come into being.And special case is opened to customization development.In practice,the rule set is assembled to realize data collection in complex environment including many application systems.


Introduction These days, identity politics is becoming the main form of politics in the advanced industrial societies of the West, and other parts of the world (Burns, 2006; Fukuyama, 2018a). Francis Fukuyama took the current government of Hungary, USA following the election of Donald Trump, and the UK concerning BREXIT as some of the examples of the shift to identity politics and nationalism (Fukuyama, 2018ab). The rise of leftist political parties in Europe and other parts of the world has also made identity politics a master concept of political struggle and bargaining. Charles Taylor also mentioned Canada in Quebec case as an example of identity politics that comes from the politics of difference and multiculturalism (Taylor, 1994). After cold war and collapse of socialism, the ideological shift from Marxian 'class consciousness' to 'identity consciousness' has also contributed to the development of identity politics especially, in the post-socialist countries in Eastern Europe, Asia and Africa (Malsevic, 2005). Concerning this ideological change, the post-1991 Ethiopia is one of the examples in which the country's constitution has provided recognition for group rights under the title of "the right of nations and nationalities" (FDRE Constitution, 1995). However, apart from conceptual analysis and objections against identity politics, several studies indicated that the growth of identity politics worldwide is not a positive development for democracy, national unity, and global political stability. Fukuyama warns, "unless liberal democracies can work their way back to more universal understandings of human dignity, they will doom themselves and the world to continuing conflict" (Fukuyama, 2018a). The rise of identity politics is, in fact, a significant encounter to the overwhelming liberal politics of many countries in the West. The majority versus minority relationship, emigrant issues, political representations of emerging cultural groups related to gender and LGBs (lesbian, gay and bisexual movements) are significant challenges against the individualist liberal system or commonly called "conservative liberalism". The rise of populist nationalism and other movements enticed by collective interests and group rights are also becoming significant encounters of "libertarians" of the politics of liberalism in general. Charles Taylor described these kinds of challenges as "the need and the demand" for the politics of recognition (Taylor, 1994); whereas Fukuyama named it as the struggle for "identity politics" (Fukuyama, 2018a). According to Taylor, the "need" for the politics of recognition is a driving force behind nationalism movements in politics. On the other hand, the "demand" comes from the politics of difference or multiculturalism, which is linked with the supposed defining characteristics of human beings as a cultural group and the demand for political representations in the political space upon group or cultural rights and interests (Taylor, 1994). Charles Taylor associates identity politics with social institutions and the differential social roles and moral duties which individuals with their differential roles and positions constitute those social-political institutions (Taylor, 1994). Burns also describes identity politics in terms of its focus on the nature, allocation, and exercise of a basic form of power in any society or political community (Burns, 2006). In this way, identity politics is conceptualised with two approaches and political practices: conThis paper approached the concepts of self-other dialectic and "the politics of recognition" from the aspect of Hegel's self-consciousness chapter in the Phenomenology of Spirit. Various authors attribute Hegel as a source and inspiration for the current theories of identity politics. This article is, therefore, focused on examining the implication of Hegel's idea of 'recognition' and 'selfconsciousness' on the contemporary debates of identity politics. Hegel has an enormous contribution to the current debate on identity politics. This article shows that with specific reference to the Phenomenology of Spirit, Hegel's understanding of 'recognition' in terms of the dialectic of consciousness is vital to see the contemporary theory of the politics of recognition in a broader epistemological and ontological basis. When it comes to the more practical and empirical political situation of these days, his idea of freedom and recognition has many important insights that support constitutional liberal system to handle 'needs' and 'demands' of recognition raised in identity politics. As Hegel has emphasised in many of his works, in the progress of human history, state (including the established institutions) is the Absolute Spirit that actualises the reciprocal freedom and mutual recognition of individuals in a broader political space. Based on these Hegelian insights, the study concluded that education, deliberative democracy, and institutions are substantial to handle competing 'needs' and 'demands' of recognition in identity politics without granting group rights and interests a constitutional recognition.


— The purpose of this paper is to describe the construction of the educational project "the development of ICT competence among teachers at Universidad de La Sabana" in Colombia. ICT Competence for Education (CIE) is defined as the ability of teachers to appropriate, integrate and innovate teaching practices and enhance students' learning through the use of Information and Communication Technologies (ICTs). In turn, the project responds to two essential aspects in the ongoing training of teachers: The integration of ICTs into the institutional curriculum on the one hand, and the role of ICTs in the improvement of the quality of education, on the other. In this regard, the construction of the project is part of the culture of innovation that the University aims to achieve through the integration of ICTs. As part of the process, an instrument was designed in order to assess ICT competence for education. In addition, the corresponding institutional regulations were obtained. The design of the instrument considered four standards: the use of technologies and the development of ICT competence, the integration of ICTs in the teaching process, the promotion of students in order to favor ICT-mediated learning and innovation in the teaching practice through the use of ICTs.

Known properties of cosmic microwave background radiation, produced no doubt by seesaw motion of sought-for dark matter, which fills ambient space, give materialistic substantiation to fundamental laws both of classical and quantum physics. According to E. Noether`s theorems, spatial homogeneity and isotropy of cosmic background radiation and, consequently, the same properties of dark matter validate the classical physics conservation laws of momentum and angular momentum, correspondingly, whereas observed invariability of nature processes on starting moment validate the energy conservation law. The fact, that microwave background radiation (the most powerful among cosmic one) has the blackbody spectrum at ~2.7 K, shows that dark matter is in equilibrium seesaw motion at this temperature. From thermal energy of such dark matter motion (with the speed of electromagnetic waves 3108 m/s) follows that dark matter effective mass, which produces seesaw motion, is ~1.210-39 kg. Maximum wavelength of microwave background radiation (~1.910-3 m) means the amplitude (damping length) of seesaw motion for effective mass of dark matter, therefore the action function of such seesaw motion of dark matter is ~710-34 Js. This value corresponds well to Planck`s constant (6.610-34 Js), which is an action function too, and this fact discovers Planck`s constant origin from dark matter seesaw motion. Such obtained result gives materialistic base to Heisenberg`s principle of uncertainty and to all others conceptions of quantum physics. Damping length of seesaw motion of dark matter let estimate the density of dark matter (≥510-27 kg/m3), which corresponds well to the space matter density for stationary Universe.

To solve the problem of vehicle adhoc network reliability is not high and multi-channel hidden terminals, we propose a multi-channel MAC protocol CAMP(cooperation-based asynchronous multi-channel MAC protocol) based mechanism for asynchronous cooperation in VANET. CAMP add to cooperation mechanisms in asynchronous multi-channel environment, the proposed scheme nodes cooperation in order to obtain the channel state information and status information to other nodes, thus a good solution to the hidden terminal problem multichannel transmission process, to achieve high mobility environment under the reliable transmission of data. The simulation results show that CAMP has better performance than IEEE 1609.4 standard, AMCP protocol, AMCMAC protocol on collision probability of SCH, safety messages delivery ratio.


The authors have calculated the orientation of the 2p state of atomic hydrogen induced by the impact of 100 eV electrons and positrons in simplified versions of the second-order Born and Faddeev-Watson approximations. These quantal approximations are compared with a semiclassical theory.


Boiling of nanofluids is reported to exhibit conflicting heat transfer trends compared to base liquids. On one hand, a deterioration of heat transfer in nucleate boiling regime and on the other hand a spectacular enhancement of critical heat flux are reported [S. M. You et al., Appl. Phys. Lett. 83, 3374 (2003); D. Milanova and R. Kumar, ibid. 87, 233107 (2005)]. The analysis and interpretation of these trends have so far been focused on the effect of nanoparticles on surface roughness, nucleation site density, and the use of hydrodynamics model for critical heat flux. In this letter a basic experiment is performed to propose a different approach to understand the mechanism through which the presence of nanoparticles acts on heat transfer during boiling of nanofluids. Pure ethanol and ethanol with aluminum particles evaporating on a hot polytetrafluoroethylene surface are investigated. The results indicate that the nanoparticles promote the pinning of the contact line of the meniscus and sessile drops. Th...


Based on the Beckmann method, a new quantitative method for the study of multi-particle azimuthal correlations is proposed. Collisions of 1.2A GeV Ar+KCl in the LBL streamer chamber are analyzed with this new method and the original Beckmann method, respectively. Theexperimental results have been compared with the Vlasov-Uehling-Uhlenbeck model predictions for different nuclear equations of state. Using the new method, the incompressibility of nuclear matter can be estimated.


Results are presented from experimental studies on the implosion of arrays made of wires and met alized fibers under the action of current pulses with an amplitude of up to 3.5 MA at the Angara 5 1 facility. The effect of the parameters of an additional linear mass of bismuth and gold deposited on the wires/fibers is investigated. It is examined how the material of the wires/fibers and the metal coating deposited on them affect the penetration of the plasma with the frozen in magnetic field into a cylindrical array. Information on the plasma production rate for different metals is obtained by analyzing optical streak images of imploding arrays. The plasma production rate for cylindrical arrays made of the kapron fibers coated with bismuth is determined. For the initial array radius of R0 = 1 cm and discharge current of I = 1 MA, the plasma pro duction rate is found to be ≈ 0.095 ± 0.015 μg/(cm2 ns). DOI: 10.1134/S1063780X13100012 Bi m


Recent interest in probabilistic logic as a formalism for machine learning has motivated the formulation of "probabilistic rule learning", where the task is to induce a set of logical rules from a probabilistic database. We start by defining rule learning within propositional, probabilistic logic. Then we show that this problem can be viewed as a regression task with integer variables. This problem is translated into Mixed Linear Programming, which is experimentally shown to provide a speedup over the current implementation. The advantage of this approach is the ability to switch between logically interpretable rule learning with binary coefficients and classical regression with rational coefficients.


A two-phase flow in mini-channels is consist with various flow regimes (such as bubble slug, annular, churn flow) according to gas and liquid phase flow rates. A previous researches revealed that in a case of slug flow in hydrophobic mini-channels, gas and liquid phase are perfectly separated by interfaces and triple contact line. In this study, the single dry slug flow experiments in circular mini-channel (D = 1.018 mm) are conducted to observe interfacial break-up phenomena in high capillary number range (Ca < 0.02). The slug is consist with D.I. water or D.I. water-ethanol binary mixtures (5% and 10%, mole fraction). On the base of previous researches, we calculate the pressure drop at moving triple contact line. In an addition, a single dry slug flow is visualized by using high-speed camera. Through the experiment, three regimes of pressure drop are observed; steady, loss, separation. As a result, criteria between steady and loss regimes is closely related to capillary number, and criteria between loss and separation regimes is related to surface tension.


The existing SignCryption with Proxy Re-Encryption(SCPRE) only provides non-repudiation and its security is weaker than that of the adaptive chosen message attack.Since there are two kinds of signcryption texts,the authors respectively provided two definitions for unforgeability: one was first-level signcryption text's unforgeability produced by the delegator and the other was second-level signcryption text's unforgeability produced by the delegatee.A new signcryption with proxy re-encryption scheme was also proposed,of which the first-level signcryption text and the second-level signcryption text all meet the publicly verifiable requirements,and its security can be proved under random oracle model.And the proposed new scheme is secure and effective.Therefore,this scheme is suitable for high security level requirements of the practical application areas.


The animal-sacrifice 1) is a part of the Soma-sacrifice and is performed on the day of the soma pressing and -offering. Among the seven haviryajfias the animal sacrifice is also separately mentioned as a kind of haviryajfias and is named as Padubandha (cf. GB 1.5.7). AB XI.7.I.I ff., we get a short description of the Pagubandha. The animal-sacrifice as a part of the Soma-sacrifice is, however, described in details by SB III.6.4.1 ff. SB XI.7.2.I explains the distinctive nature of the Padubandha by mentioning the two kinds of the animalsacrifice as follows: "One animal-sacrifice is of the haviryajfia order and the other of the soma-sacrifice. Of the haviryajfia order is that at which he (the adhvaryu) brings him (the sacrificer) the fast food, leads water forward and pours out a jarful of water and at which (the sacrificer) strides the Visnu-strides. The animal-sacrifice of the order of the Soma-sacrifice is that at which these rites are not performed". In the Br5hmana-texts we do not get detailed description of the PaSubandha. Therefore, we shall see the description of the animalsacrifice included in the soma-sacrifice only. The significance and allied problems of both of the animal-sacrifices are the same. Therefore they will be seen together.


Editor, Regardless of possible biases related to post hoc testing, a sub‐analysis can be appropriate when the primary point of interest has been reached and one wants to inspect whether sub‐groups might have reacted to treatment differently than the main group. The data presented in the recent "sub‐analysis" by Aasvang et al derive from a remarkable trial addressing the question whether discharge from the post‐anaesthesia care unit might be advisable and safe without assessment of lower limb motor function after total hip arthroplasty (THA) or total knee arthroplasty (TKA) performed under spinal anaesthesia. As the frequency of a successful fast‐track recovery was the primary endpoint, a sub‐analysis of this parameter might be suitable, but not of failed spinal anaesthesia (FSA). From the fairly large number of analysed patients (n = 1451), 57 patients (3.9%) fulfilled the criterion for FSA, ie, a patient required general anaesthesia at any time during surgery. Supplemental analgesia or sedation with remifentanil or propofol per se was not considered as FSA, unless laryngeal mask placement or tracheal intubation was deemed necessary. As clinicians, we appreciate this definition of FSA. However, between the 5 participating centres, the failure rate varied significantly from 2.2% to 7.1%. Could the handling of intraoperative pain and problems have differed substantially from centre to centre and thus influenced the rate of FSA? A third of FSA occurred in TKA and two‐thirds in THA. How should the reader interpret this difference without more details about the spinal technique? Only the rather small amounts of bupivacaine (5 mg/mL) were presented (2.2 [1.8‐2.5] mL [mean [95% confidence intervals]]), but combined for TKA and THA. These 2 procedures were put under one umbrella without mentioning the distribution between plain and hyperbaric bupivacaine, the positions in which the spinal anaesthetics were injected, and for how long the patients were kept, eg, in the lateral position before return to the supine position. All these factors could have affected the efficacy of spinal anaesthesia. There are no data about the time when FSA was diagnosed after the start of surgery. By reviewing the 57 FSA anaesthesia charts for the starting time of general anaesthesia and by using this parameter as a surrogate, it might be possible to discriminate between cases where the spinal turned out ineffective soon after incision and those where the spinal wore off gradually. Failed spinal anaesthesia was associated with no other factors but longer procedure times and younger age. This corroborates what has been known before; namely, that the duration of bupivacaine spinal anaesthesia increases with increasing dose and growing age. The findings do not allow the generalisation that intraoperative FSA is a relatively frequent outcome in TKA and THA patients. We are not sure how to interpret the authors' inference that pre‐operative identification of risk factors is not feasible. When dealing with younger patients, more complex procedures, slower surgical teams and THA (as compared to TKA), we should increase the bupivacaine dose and adapt the spinal technique in order to reduce the risk of FSA.


The analytical investigation of the relation between the depth of snow on the young stand of Sugi (Cryptomeria japonica) in the experimental forest of Yamagata University and the microtopographic factors was repeated with the aid of partial and multiple correlation coefficients. The depth of snow was measured annually for five years from December of 1965 to April of 1970. Summary of the findings is as follows : 1) The progress of depth of snow varies with the duration of measurement, but the relation between the depth of snow and the microtopographic factors shows similar trends throughout the five winter seasons.2) On the steep slope, on the convex surface and in the place which an ample supply of light, the depth of snow decreases rapidly during the spring thaw. On the other hand, the depth of snow decreases slowly in the place which has many trees over 6 m in height, but it seems likely that there is no effect of the trees under 5 m in height.3) In the latter half of the duration of snowfall the multiple correlation coefficient increases remarkably as the day goes on, and the value of its square exceeds 0. 6 in every April.


The standard of delimiting science is always an endless debate,so is that of psychology.The issue how to delimit psychology relates to the existence and development of psychology,moreover,it decides whether we have a full and deep understanding towards psychology.In the scientific field,there are natural science, human science,frontier science,cultural science and super-science and so on.Psychologists have their own standard of delimiting psychology,which shows their different philosophy,scientific perspective and intellectual backgrounds.These psychologists' standards reflect the cultural features of their era and provide various views and aspects of their understanding to psychology.


SOT-MRAM devices are promising due to a decoupled read and write path. As such, SOT-MRAM is considered robust against MgO breakdown of the MTJ. However, during switching, high current densities flow through the thin metallic SOT layer causing significant self-heating of the MTJ. We investigate the degradation of the MTJ during hybrid SOT & STT stress. The resilience to breakdown is impacted by the SOT stress because of the elevated MTJ temperature, supported by thermal simulations.


Titanium dioxide photacatalystic tehnique is a new kind of water and wastewater treatment process with great potiential application prospects. The principle and mechanism of photoelectrocatalysis on TiO_2, the application of TiO_2 are reviewed, and some questions on the application are also recommonded.


Fetal Alcohol Spectrum Disorders (FASD) are associated with changes in proliferation and induced cell losses of neuronal stem cells during development.  Alcohol induced oxidative stress has been noted in previous studies to cause chronic genomic instability and DNA damage. This damage results in the halting of S-Phase cell cycle progress and, in many cases, either induces DNA repair or apoptosis of the cell. However, alcohol-induced apoptosis has been show to work in a p53 independent fashion. Typically, proteins CDC25a and c as well as CHK-1 and 2 monitors DNA damage and help to determine cellular fate in p53 independent apoptosis.  A study utilizing alcohol treated neuronal stem cells resulted in approximately 40% of the population maintaining DNA damage without inducing p53 dependent apoptotic mechanisms. The goal of this study was to elucidate the role, expression and localization of checkpoint kinase-1 (CHK-1) during the G1-S phase transition and to determine any major difference in phosphorylated, CHK-1 between control and alcohol treated neuronal stem cells. A Western Blot was run to determine quantitative presence of Phosphorylated CHK-1 and Immuno-fluorescent staining was used to quantitatively measure the abundance of Phosphorylated CHK-1 in groups. Image analysis determined that there was a significant difference in Phosphorylated Chk-1 in alcohol-treated cells. The increased level of Phospho-CHK-1 indicates recognition of DNA damage, initiation of signaling G1/S phase transition and possible induction of apoptosis. Understanding the mechanistic changes in alcohol induced proliferation and cell losses may help in defining treatment paradigms effective in treating FASD.


The collectorless flotation behaviors of sphalerite in the presence of Cu 2+ ions have been established. The effects of pH, potential and Cu 2+ concentration on the flotation have been studied using a micro flotation cell specially designed, where the potential can be controlled by a potentiostat. The flotation results have shown that the Cu activated sphalerite displays a good collectorless floatability in a pH range of 0~13. The higher potentials can improve the flotation recovery. The surface species formed during the Cu ion activation have been examined using a special electrochemical technique—a composite sphalerite electrode. Zinc deficient sulfide (Zn 1- x Cu x S) and Cu poly sulfide (Cu y+z S y ) species have been determined. They are responsible for the collectorless flotation of sphalerite. In additional, they can improve the conductivity of the sphalerite surface.

Introduction An interactive narrative is an education, training, or entertainment experience, based on a narrative that is guided by authorial intent. Interactive narratives have two important characteristics: some form of authorial intent as represented by the narrative structure and an affordance for autonomy of player characters. Technologies for constructing engaging interactive narratives have been springing up more and more rapidly in recent years (see [4] for a recent survey). As this field gains momentum, new and exciting opportunities arise for the application of novel machine learning methods. In this paper, we will present a brief overview of interactive narrative, formalizing the problem in a manner amenable to computational inquiry. Then, we will survey recent work based on the use of statistical machine learning methods to solve various aspects of interactive narrative problem. We will also describe certain aspects of interactive narrative that present new and exciting challenges for the machine learning community such as non-stationarity and new definitions of optimality. Lastly, we will describe the aspects of the interactive narrative problem that we feel will both benefit the most from the application of machine learning methods as well as provide some interesting challenges for the machine learning community.

Farm households in the highlands of western Kenya are improving their livelihoods using a community credit scheme and a set of decision-support tools. Depleted soils, due to continuous maize cropping, together with Striga infestation, have trapped farmers in a cycle of low yields and poor soil fertility. To diversify into higher value crops on their limited land, households must intensify maize production. The credit scheme lets farmers invest in fertilisers, while the decisionsupport tools help borrowers with land management questions. Although developed in Kenya, these tools are applicable to many areas of Africa dominated by poor, food-deficient, semi-subsistence farm households. In Kenya, the tools are promoted by a World Bank-funded project, and they have also been introduced in Uganda.


Abstract: Nepalese migrants who are involved in businesses in Scandinavia are survivals in the race of high tech and cross cultural constraints. They are adaptive to use knowledge and education and are also able to learn skills in order to exploit the situation in their favour. A hypothesis is tested among Nepali migrant entrepreneurs by exploring their experiences regarding migration, strategy and adaptability in context to Scandinavia. The research has attempted to find the answers of following questions: What are the strategies and traits in adaptation process? Where do Nepali migrant entrepreneurs position themselves? What are the motives behind building organizations and networks in destination? Who are Nepalese entrepreneurs in Scandinavian context? Does this particular phenomenon have any significance in explanatory approach from social science perspective? Answers to these questions will add further knowledge to specific Nepalese migration phenomena their adaptability and learning experience in this region. Various exploration tools were used to identify the focal group and a set of semi structured questionnaire distributed whereas short open questions were asked to the informants concerning questions about Nepali community, entrepreneurship, potentiality and problems to understand underneath reality. Intensive interviews were carried out to both focal group and informants in order to generate qualitative data. Interview data were examined with migration theories, struggles, adaptation relating to entrepreneurship as a situated learning process. In order to make more understanding, a historical development of Nepalese ethnicity in migration process has been extensively discussed. Survival strategies have been interpreted as learning to adaptability and building identity as interpreting them as productive immigrants. The research finds Nepalese migrant entrepreneurs are highly adaptive and optimistic and are in search of building identity for both community and business. The research is expected to beneficial to all those who have interest and nexus with Nepalese community and their situation and their gradual progress in learning in context to Scandinavia. The study will be useful to follow immigration policy for ethnicity and integration. (Less)


Abstract The purpose of our study was to characterize the diet of the common genet Genetta genetta in the Djurdjura Mts., north of Algeria. Through a year-round survey, we collected 360 feces and identified 1970 items. Arthropods (33%) and mammals (25%) were dominant, followed by wild birds and plants. The wood mouse Apodemus sylvaticus (65% within mammals) and Coleoptera (66% within arthropods) were dominant throughout the seasons. We observed striking seasonal variations in the common genet's diet, with arthropods peaking in summer, mammals and wild birds dominating in winter, and energetic plants more consumed in autumn. Our study underlined the opportunistic feeding habits of the common genet with high values of trophic indices throughout the seasons, and the species' capacity to adjust its food spectrum on seasonal resource availability. Our results confirmed that the common genet has an intermediate diet between generalist and specialist, feeding on a wide spectrum of items but relying on the wood mouse as the main energetic source. The diet of the species in Djurdjura Mts. included a great proportion of arthropods, thus, reflecting the "Mediterraneity" of the feeding spectrum of the common genet in northern Algeria.


The number of Android malware apps are increasing very quickly. Simply detecting and removing malware apps is insufficient, since they can damage or alter other files, data, or settings; install additional applications; etc. To determine such behavior, a security engineer can significantly benefit from identifying the specific family to which an Android malware belongs. Techniques for detecting Android malware, and determining their families, lack the ability to deal with obfuscations (i.e., transformations of application to thwart detection). Moreover, some of the prior techniques are highly inefficient, making them inapplicable for real-time detection of threats. To address these limitations, we present a novel machine learning-based Android malware detection and family identification approach, RevealDroid, that provides selectable features. We assess RevealDroid to determine a selection of features that enable obfuscation resiliency, efficiency, and accuracy for detection and family identification. We assess RevealDroid's accuracy and obfuscation resilience on an updated dataset of malware from a diverse set of families, including malware obfuscated using various transformations, and compare RevealDroid against an existing Android malware-family identification approach and another Android malware detection approach.


The problem of formulating self-consistent local and global stability exponents is shown to require global separation of variables. Posing the separation of variable problem, we see that many such separations are possible, but only one is consistent with both Hamiltonian dynamics and the boundedness requirement for a Lyapunov transform: the determinant of the modal matrix must be constant. Such stability exponents are invariant to any linear transformation of variables, and both the local stability exponents and modal matrix appear to be point functions in the original space, and introduce a true coordinate frame. Methods are presented to perform this separation at equlibrium points, about periodic orbits, and along general trajectories. Results of numerical experiments are given.


This paper concerns a brochure from the time of the Great Sejm entitled "Defence of Jan Zamoyski - the Chancellor and Grand Crown Hetman", Zamośc 1790 by Joachim Owidzki (also ascribed to M. Czacki). It is a polemic between the author and Hugo Kollątaj, who attacked Jan Zamoyski in some of his letters written in the period of the Great Sejm. Owidzki was supported by Stanislaw Staszic and they both were associated with Andrzej Zamoyski, the Grand Crown Hetman (1764-1767), the entailer and his family. Owidzki's brochure was probably meant to protect the Zamoyski fee tail estate against parliamentary plans to tax the estate for the benefit of the army. Yet, the dispute over J. Zamoyski between Kollątaj and Staszic, outlined in this paper, had a considerably wider dimension because the example of the chancellor and grand crown hetman was only used to illustrate the political debate on the structure of reforms in the country which was being conducted at that time. Kollątaj and Staszic shaped this significant historical figure in a way that corresponded with their own concept of saving the collapsing Polish Republic.


Synthetic organophosphorus compounds are among the most toxic substances known and represent the largest class of insecticides widely used in agriculture. Chlorpyrifos is a member of organophosphorus class insecticides. Chlorpyrifos analysis is carried out conventionally by gas chromatography by using NPD (1), ECD (2) and MS detectors (3). Liquid chromatography (HPLC) (4) and liquid chromatography determinations combined with ELISA is also reported (5). However, in developing countries the chromatographic analysis is financially prohibitive for these kind of analyses. Thus, development of reliable and fit for purpose methods of analysis for mixtures of pesticides with the use of simple and relatively inexpensive instrumentation is an appropriate objective. Hence, electroanalytical techniques provide an inexpensive alternative for pesticide analysis (6). Chlorpyrifos (CP) is known to be electroactive and its differential pulse polarographic (DPP) behavior was investigated (7). In our study, differential pulse cathodic adsorptive stripping voltammetric behaviour of and of CP was studied. Effect of electrolyte, deposition time, deposition potential, temperature effect, pH effect, mercury drop dimension, sweep rate was the parameters optimized in our experiments. The complex matrix of the food samples limits us to determine this pesticide without any pre-separation step. As we noticed from the literature, a single study includes the usage of SPE prior to the voltammetric analysis (8). The developed method was adopted for wine samples. The recovery of seperation techniques were compared in our study. The main steps applied to wine sample before the volammetric measurement is liquid-liquid extraction (LLE), seperation on a coulumn (SPE) and concentration of the analyte. The effect of LLE solvent type and different coulumns were tested for the sample preparation step. Calibration curves were linear in a range of 0.2 200 ng/mL with the detection limit of 0.14 ng/mL and quantitation limit of 0.45 ng/mL. The RSD was calculated as 11% for 0.2 ng/mL concentration. The method was validated with spiked wine samples. The results were compared with GC-ECD.

Within Saʿadya Gaʾon's enormous literary output, his Arabic version of the Pentateuch, known as the Tafsīr , carries a special weight. This early Arabic translation of a major section of the Hebrew Bible has enjoyed much popularity among Arab-Jewish communities and has even been incorporated into some of their prayer books, e.g., that used by the Jews of Yemen. The Coptic Church in Egypt, too, made use of certain sections of Saʿadya's Arabic rendering. Several subsequent Arabic translations by Middle Eastern or North African Jewish translators are based to varying degrees on the Tafsīr . Many scholars believe that the name Tafsīr was probably chosen by Saʿadya as a way of indicating that his version includes deviations from the plain or apparent meaning of the Hebrew text, especially in cases in which anthropomorphism can be inferred, or in which the translator abbreviated the original text because of some "unnecessary" repetition. Keywords: Coptic Church; Egypt; Hebrew Bible; Jews; Saʿadya Gaʾon; Tafsīr


Abstract:In this article, I explore the individual and systemic impact of hegemonic masculinity on college men serving as peer educators in sexual violence prevention programs. This ethnographic study was completed during the 2017–2018 academic year at a public university in the Southwest. Following an organization in the midst of a great deal of transition, I observed how hegemonic masculinity, particularly by way of male/men privilege and cisheteropatriarchy, was entrenched, actualized through curriculum, and occasionally resisted and critiqued. Through this article, I outline how the program allowed college men participants opportunities for further self-awareness around hegemonic masculinity, yet the program's systemic outcomes did not always play out in expected ways. Implications for future practice and research are discussed.


This paper discusses a simple method of computing independent strips under certain reasonable approximations. It is shown that, if the method is regarded as if it were computation by polynomials, the order of the polynomial is decided by the nature of the control provided and not by the number of controlled models. This conclusion should throw some light on the vexed (and perennial) problem of the choice of orders for polynomials.

AbstractLeadership is one of the hallmarks of the pharmacy profession. Developing effective leadership skills in students of pharmacy is necessary to allow the profession to continue to move forward. The University of Mississippi School of Pharmacy instituted a program to enhance the leadership skills of the elected student body and class officers, and the officers of the student chapters of the national professional pharmacy organizations. The program consists of regular meetings with student officers to discuss the elements of good leadership, breakout exercises, and discussions of problems and issues encountered by leaders with student input on potential strategies for resolution of those issues. The program also includes a peer evaluation of each organization president at the midpoint of their tenure with constructive feedback provided on their performance. The leadership program has been effective in enhancing the quality of the performance of elected student leaders and in attracting more qualified ...


The solitary caster of seed is one of the most prominent leitmotifs in the art of Vincent van Gogh, one that appears in his first drawings and recurs with frequency in his painted oeuvre. This study traces the genesis of his interest in the motif, and its acquired meaning — personal, art-historical, religious — in his work. It explores Van Gogh's emulation of Jean-Francois Millet's mode of infusing secular motifs with spirituality, and focuses upon the impact of Millet's Sower and the biblical parable that inspired it. The significance of Van Gogh's sowers is amplified and enlarged by his late-life fascination with harvest themes, particularly the reaper, who is both the antithesis and counterpart of the sower in the metaphorical cycle of life and death to which Van Gogh was increasingly attentive as he contemplated suicide at St.-Remy and Auvers. Van Gogh's many images of planting and harvest are shown to be parts of a symbolic pictorial vocabulary that depends on the example of Millet and speaks the sam...


SUMMARY An experimental transonic axial-flow-compressor rotor was designed, constructed, and tested to supply experimental blade-element data for double-circular-ac airfoil sections. The rotor was designed to operate at a corrected tip speed of 1000 feet per second, to obtain an average total-pressure ratio of 1.34, and to pass a corrected specific weight flow of 30.7 pomb per second per square foot of frontal area. The hub- tip radius ratio at the rotor inlet was 0.5. This report presents the rotor-blade-element performance at 60, 80, 90, and 100 percent of design speed. High blade-element losses were noted near the tip of the rotor at design speed. The major portion of this loss is attributed to high blade loading. Excessive shock losses were not noted up to Mach numbers of 1.08. The measured blade-element losses are in good agreement with pre- viously reported rotor-blade-element data. Comparisons of measured deviation angles with angles determined by Carter's


It is more than half a century since Schoenberg first introduced rhythmically organized speech, with relative—not absolute!—pitch outlines defined, into his music; significantly enough, the abandonment of normal song first happened in his earlier atonal works, such as Pierrot lunaire and Die Glückliche Hand (which I call 'The Knack' in English). That this disintegration of pitch followed hard on the heels of the disintegration of tonality is a simple historical fact which criticism has hitherto altogether neglected. We have been so preoccupied with the loss of key on the one hand and the speaking voice's loss of pitch on the other, that we have never stopped to consider that—and, most important, why—the two belong together.


BACKGROUND AND OBJECTIVES
Adolescence is a time during which not only gambling, but also tobacco, alcohol, and illicit drug use, usually begin. The purpose of this paper is to provide an updated review of the literature on gambling and its associations with tobacco, alcohol, and illicit drug use among US youth.

METHODS
An electronic literature search of PubMed and PsycInfo was conducted for studies since 2000 using the keywords "smoking," "tobacco," "nicotine," "cigarette," "gambling," "adolescence," "adolescent," "alcohol," and "substance use." Ten articles with unique adolescent samples were located. Because the articles varied in regard to definitions of gambling, tobacco, alcohol, and drug use, we provide a qualitative review of included studies.

RESULTS
Gambling prevalence rates ranged from 44.3% to 68% in national telephone-based surveys, from 24.4% to 86% among students in school-based surveys, and from 22.5% to 47.4% in surveys of convenience samples. Significant associations were reported between gambling and tobacco use (4/7 articles), gambling and alcohol use (7/8 articles), and gambling and illicit drug use (7/8 articles).

CONCLUSIONS
The wide range in rates of gambling and problem gambling may be due in part to differences among the studies in participant samples, sampling techniques, assessment time frames, and definitions of gambling. Despite methodological differences, most studies showed significant associations of gambling with tobacco, alcohol, and other illicit drug use.

SCIENTIFIC SIGNIFICANCE
As accessibility to gambling increases, more research is needed to inform prevention efforts and identify youth at-risk for gambling and other high-risk behaviors.

For many centuries the Southern Ocean, with its Roarin' 40s and Screaming 50s, has been a mythically remote part of our planet: pristine, freezing, foreboding; the domain of hardy adventurers and whale hunters. Today we know that it has been one of our most important assets as a regulator of regional climate and global atmospheric CO2 for at least the past million years.


Quality initiatives (QIs) refer to a wide variety of tools and techniques adopted by organisations across the world in order to improve quality. Organisations are being awarded with prestigious quality awards (QAs) recognising the ongoing efforts they make in improving quality. This paper attempts to explore the influential nature among QI adopted and QA won with respect to winners of Indian QA in terms of perceived understanding, success in implementation and effect on results/performance. This empirical study shows that managers accept the existence of such a mutual influence across different contexts like size, type and sector of the industry, before the company has won a specific QA. The study however is inconclusive about the mutual influence among QA and QI, after an organisation has won a specific QA.


Upregulation of the prorenin receptor (PRR) in glomeruli leads to diabetic nephropathy and high glucose increases PRR expression in mesangial cells in vitro. Angiotensin II (Ang II) upregulates PRR in the collecting duct (CD), which is the main source of prorenin in diabetes. However, there is no evidence indicating that the expression of the PRR in the CD is altered during this condition. To test the hypothesis that PRR expression in the CD is augmented by high glucose and that this effect is prevented by insulin, we examined the PRR mRNA levels in renal inner medullay tissues of db ‐/‐ knockout mice and wild type mice. PRR transcript levels were increased in db ‐/‐ knockout mice (129 ± 8 vs. 100 ± 6 %; P<0.05), which exhibited high blood glucose levels (431 ± 3 vs. 110 ± 11 mMol/L). Treatment with insulin (0.1U/implant × 30 days) prevented this upregulation yet in the presence of chronic Ang II infusion (68 ± 6 % vs. 100 ± 6 %; P<0.05). In M‐1 cells, a mouse collecting duct cell line grown in normal glucose levels (5 mM), PRR mRNA levels were downregulated by 100 nM insulin for 8 hours (68 ± 4 % vs. 100 ± 5 % P<0.05), and even further with concurrent treatment of 30 mM glucose (45 ± 8 % vs. 100 ± 5 %; P<0.001). No significant effects were found by high glucose alone. The downregulation of PRR expression in the CD by insulin even in the presence of high glucose suggest that insulin may protect the kidney from tubulointerstitial damage in diabetic subjects.

Despite entrenched corruption and police interference, community organisations lead the fight against HIV among drug injectors and sex workers in Ukraine, reports Richard Hurley


It is well known that coherent VLF signals injected into the magnetosphere from Siple Station, Antarctica, often show temporal growth of 20–30 dB and emission triggering, as observed at the conjugate point, near Roberval, Quebec. In a new kind of experiment it has been found that when the input power to the transmitting antenna is reduced below a 'threshold' value Pt, growth and triggering cease. Below Pt the output is proportional to the input. In one typical experiment the peak received power increased by 24 dB when the input power to the antenna crossed the threshold value of 1000 W (estimated radiated power of 10 W). The value of Pt varied widely depending on the duct involved and on the time, changing as much as 10 dB in less than 1 hour. As the power was lowered during multipath propagation, the last duct to be cut off was found to terminate nearly overhead at Siple, as was expected, assuming all ducts to be equally active. Minimum radiated power for growth and triggering was 1 W. One possible explanation for the threshold effect is background noise (e.g., plasmaspheric hiss) that prevents the instability from getting started. Another is a drop in temporal growth rate to below zero at low signal level. Measurement of Pt might possibly serve as a ground-based diagnostic for magnetospheric flux levels, assuming calibration by satellite particle detectors.


On the basis of a local-projective (LP) approach we develop a method of noise reduction in time series that makes use of nonlinear constraints appearing due to the deterministic character of the underlying dynamical system. The Delaunay triangulation approach is used to find the optimal nearest neighboring points in time series. The efficiency of our method is comparable to standard LP methods but our method is more robust to the input parameter estimation.
The approach has been successfully applied for separating a signal from noise in the chaotic Henon and Lorenz models as well as for noisy experimental data obtained from an electronic Chua circuit. The method works properly for a mixture of additive and dynamical noise and can be used for the noise-level detection.


Electrochemical reduction of Deoxycholic acid (DCA), as important biological molecule has been studied in 0.05 M KH2PO4 aqueous methanol solution (1 : 1, v/v) at a multiwalled carbon nanotubes modified electrode. Based on cyclic voltammetry, Tafel plot, the possible mechanism of the electrochemical reduction of DCA was investigated, as well as DCA mechanical calculations. The transfer coefficient, α, the exchange current density, i0, the diffusion coefficient, D0 at the MWCNT modified GCE were determined as 0.505, 5.655×10−7 A/cm2 and 1.579×10−5 cm2/s, respectively. The results of chronoamperometric suggested that the reductive product of DCA was the corresponding hydroxymethyl compound in an over-all four-electron process.


Therapeutic vaccination of antigens in oil emulsions is an approach becoming increasingly popular. Water-in-oil emulsions enable the formation of a depot, a slow passive antigen release and a decelerated antigen degradation. Furthermore, particularly advantageous for peptide vaccinations with a low clinical response rate is the increased immunogenicity and activation of CD8+ and CD4+ T-cells. Therefore, the use of personalized peptide vaccination cocktails in oil emulsions are tested in the treatment of cancer patients. An equal peptide distribution in the emulsion is striking for a successful depot effect to ensure the optimal efficacy and additionally, to enable reliable drug release analytics. First, the stability of the generated peptide-Montanide ISA™51 emulsion was demonstrated with a cocktail of heterogeneous peptides for 24 h in room temperature. Furthermore, we developed a simple peptide extraction method to investigate the equal peptide distribution in a Montanide ISA™51 emulsion in the syringe after mixing. Peptides were successfully extracted from a peptide-Montanide ISA™51 vaccination cocktail in sufficient volume for analysis and an equal peptide distribution in the syringe was verified via HPLC.


This study examined the relationship between transparency and reputation of insurance companies in Port Harcourt. The study adopted a cross-sectional survey in its investigation of the variables. Primary data was generated through self-administered questionnaire. The population of the study was 479 employees of 25 insurance companies in Port Harcourt. A sample size of 218 respondents was calculated using the Taro Yamane's formula for sample size determination. The hypotheses were tested using Spearman Rank Order Correlation with the aid of Statistical Package for Social Sciences version 23.0. The study findings revealed that there was a significant relationship between transparency and reputation of insurance companies in Port Harcourt. The study thus recommended that management of deposit money banks should develop a plain and transparent leadership style to avoid any form of doubt and insecurity because this will go a long way to help in building the commitment of the employee.

In his article "About the Destruction, Continuation, and Transformation of Art" Frank Maet offers an answer to the question raised by Arthur C. Danto's thesis how to discern art from non-art? Maet considers art from the perspective of a technologically mediated reality and he distinguishes three different views on contemporary visual art: the destruction, the continuation, and the transformation of art. Maet considers these three artistic views as different strategies to deal with our current technological condition and evaluates the merits of each of them. He argues that our thoroughly designed reality turns the strategy of artistic destruction into a dangerous and sometimes even life-threatening strategy and that existing theories of art advocating the continuation of art fall short in taking into account popular and commercial products. According to Maet, we have to opt for a radical transformation of the concept of art and redefine art in light of the current digitalization as a specific kind of technology.

Abstract We give a graphical calculus for the invariant tensors of the eight dimensional spin representation of the quantum group Uq(B3). This leads to a finite confluent presentation of the centraliser algebras of the tensor powers of this representation and a construction of a cellular basis.


A theoretical model describing the noise conversion characteristics of wavelength converters based on XGM in SOA is established in this paper. The numerical simulation results show that the input pump power and probe power have direct influences on the noise conversion. In an appropriate range of input power, the noise can be effectively suppressed and the quality of the converted signal is improved.


The principle of equivalence underlying the general theory of relativity implies the equality of the inertial and gravitational masses of a body. The former of these has a contribution from the gravitational interaction besides those from the strong, electromagnetic, and weak interactions, and in laboratory experiments, in which gravitation is negligible, the equivalence principle has been confirmed to an accuracy of 10ÿ12. In massive astronomical objects the equality of the two masses should also be left intact by the gravitational contribution. That this is indeed the case has been shown by University of Washington scientists using data from three decades of lunar laser ranging (with light being reflected by mirrors placed on the Moon) and calculating the acceleration of the Earth and the Moon toward the Sun. Taking into account the different compositions of the Earth and the Moon, it is shown that the equivalence principle is obeyed to an accuracy within 10ÿ3. Indicative of the high precision of the study, the contribution of the gravitational energy to Earth's inertial mass is as low as 4:6 10ÿ10. Source: http://ojps.aip.org/prlo/top.html


Mongolian nationality has rich non-material cultural heritages,most of which are taken into the nine categories of the ten issued National-grade Non-material Cultural Heritages,except one category of "traditional drama".Drama is not prosperous in the Mongolian nationality's non-material cultural heritages,the reasons for it are firstly,Mongolia is a typical nomad nationality,the external condition for generation and development of drama—city has long been absent,which influences the appearance of Mongolian drama.Secondly,when the Mongolian nationality entered and was dominant in the city of the central plains(comprising the middle and lower reaches of the Yellow River),the Chinese language Yuan poetic drama set to music was flourishing.Yuan poetic drama absorbed many artistic elements of minority literature such as Qidan,Mongolian nationalities,etc.and became an artistic form liked by Han,Mongolia,and other nationalities,therefore,Mongolian nationality did not have drama works of their own national language.After the foundation of the new China,Mongolian drama appeared and was developing step by step.


The study investigated the improvement of different teaching strategies on students' attitudes and conceptual understanding in Grade 11 Mathematics. It used a descriptive-correlational research design, and survey questionnaires were administered to the randomly selected students in the three senior high school classes of Surigao City National High School. Findings revealed that students' attitudes do not vary across the three approaches. Data further showed that the average rating scale of the students in terms of their grades is 86-89, which entails very satisfactory performance. Moreover, the level of students' attitudes is separate from improving conceptual understanding across the three strategies. Students' attitudes and conceptual understanding have no relationship except problem-based learning when compared to conceptual understanding. Hence, teachers' strategies in general math are associated with the student's attitudes toward learning mathematics.


Objective To study the effect of Carbon Dioxide Insufflation on arterial blood gas and hemodynamics in the elderly. Method Sixty gerontal patients undergoing laparoscopic cholecystectomy during endo-trachea general anesthesia were randomly selected. Artery blood samples were drawn to measure pH,PaCO2,PaO2 and SaO2. The vital signs were monitored simultaneously. Results PaCO2 was significantly increased on the 10th min, 30th min after the insufflation and 30th min after the deflation, compared with pre-inflation value (P0.05);but pH wassignificantly decreased; PaO2,SaO2,blood pressure and heart rate remained un-changed (P0.05).Conclusion Carbon Dioxide Insufflation can obviously influence on arterial blood gas in the aged, but keep stable hemodynamics.


The purpose of this article is to study the relationship between the economic sphere and the phenomenon of corruption was also seen by some economists as Leff (1964), Huntington (1968), Him (1985), Beck and Maher (1986) who argue that this relationship is beneficial to the economy because it would improve economic efficiency. We can also examine the creation of Transparency International and the work of Mauro (1995), which form the first empirical estimate for the same query. According to P. Mauro (1995), the harmful nature of corruption on investment and economic growth and hence the essential role played by the state in the development of nations. In this context, we must first of all, to study in more detail the concept of corruption, its definitions and its genesis. Then we try to develop approaches to corruption. For most economists D. Kaufmann et al. (2007), corruption has roots in the content of economic power. Corruption is rooted in the structural weakness of local institutions and the failure of public policy and decision control officials to lute against this social evil. Finally, we focus on the determinants of corruption ie the micro-economic determinants and macroeconomic determinants.


Scientific workflows in life sciences are usually complex, and use many online databases, analysis tools, publication repositories and customized computation intensive desktop software in a coherent manner to respond to investigative queries. These investigative queries are generally ad hoc, ill-formed, and often, used only once to test a single hypothesis. In such cases, developing customized workflows becomes a major undertaking, rendering the effort truly expensive, prohibitive and resource intensive. Such high development costs often act as deterrents to many interesting queries and promising on-time scientific discoveries. In this paper, we introduce a new query language that combines workflow features for scientific applications, called BioFlow, that exploits many recent developments in internet communication, databases, wrapper and mediator technologies, ontology, and data integration. BioFlow is a declarative language that abstracts these features to help hide most procedural aspects of mediation, data integration, communication protocols, data extraction and workflow details. We will demonstrate that fairly complex workflows can be effortlessly and declaratively expressed in BioFlow in an ad hoc fashion at minimal costs. We also report a prototype implementation of BioFlow in Windows VB .NET that includes most of its powerful and representative features as proof of feasibility of our proposal.

Factors influencing and producing thixotropy in these systems are discussed. The possible application of thixotropic gels as therapeutic agents is presented.


Nanostructure TiO2 was prepared in the form of sol-gel by a hydrolysis process and fast-quenching method. The prepared sample characterised by different techniques. It was found that the particles have nano-amorphous structure. Due to fast-quenching effect, the fabricated sample at such annealing treatment has many oxygen vacancies. The measured band gap found to be 1.2 eV, which has strong transmittance in vis-NIR region. The photocurrent measurement using capacitance probe method of a black body radiation and few wavelengths at NIR showed good sensibility.

Frederic Chopin was often romantically idealized or interpreted not only in the nineteenth century, but even up to the middle of the 20th century. His name reminded the people of an lonely alien who desperately missed his home-land, a romantic man who were involved with the sensational love-affairs, and a delicate artist who died at an early age with tuberculosis. However, from the 1950s on, the argument against this romantic views began to emerge, emphasizing that the life and music of Chopin was misinterpreted with the elements of so-called `myth` and `romantic legend`. The social climates and the individual dispositions play an significant role in causing changes of views about Chopin. In fact, it is helpful to understand an artist better, if we analyse the relationship between the historical facts concerning him and the diverse views about him. Thus this study begins with a discussion of the elements which causes the changes of views on the artists. Then it explains the diverse views on Chopin prevalent in the 19th and the 20th centuries, and presents the task which these diversity Imposes upon us.


The changes of amino acids in the cotyledons of spring - and winter radishes were analysed during the abscisic acid (ABA). ABA plus cycloheximide (CH) and ABA plus polyamine (PA) treatment. The total contents of amino acids were increased in spring radishes, and decreased in winter radishes by ABA. The contents of hydrophilic amino acids, proline, glycine, serine and cysteine in spring radishes (expecially proline), and of cysteine, leucine and phenylalanine in winter radishes (expecially cysteine and leucine)were increased, CH treatment resulted in the accumulation of amino acids by the inhibition of new synthesized protein, which synthesized against ABA induced dehydration both of radishes. On the contrary, the contents of amino acids were decreased in spring radishes, and increased in winter radishes during PA treatment. These results indicated that the accumulated hydrophilic amino acids and new synthesized proteins induced the adaptation of dehydration against stress and the role of ABA in accelerating of stress adaptation was mediated by polyamines.


Based on the under-construction Metro Line 4 and 6 of Wuhan,an FLAC two-dimensional numerical model was established and the deformation of the railway-bridge pile foundation caused by different loss rates of stratum and excavation sequences of shield tunnel was studied profoundly.According to the results of numerical simulation,when the loss rate of stratum is between 0.2% and 1.5%,the deformation satisfies the safety requirements.However,when the rate is greater than 1.5%,measures must be taken to control the deformation of the railway-bridge pile foundation and the pre-reinforcement of soil around the tunnel is a recommended way.


— In our politically fragmented urban areas, sheriff's police services, like all municipal services, are distributed free of any direct charge. This study attempts to determine the optimal quantities of county police activity each political district should receive as well as their matching tax bills. The outcome of the analysis is pronouncedly influenced by the peculiar nature of externalities that occur in the provision of urban law enforcement services. Achievement of optimality conditions indicates an inverse relationship between sheriff's per capita expenditures and per capita tax base values of the participating political units.

Cyprus, the third largest island in the Mediterranean, came under Roman domination during the late Republican Civil War. Due to its position outside of the political and strategic centres of the Empire, Roman Cyprus was something of a terra incognita among ancient historians. This e-book investigates communication between this "quiescent" province and the Roman emperor through the exploration of fascinating epigraphic evidence concerning the imperial cult and imperial representation on the island (dedications, statues, oaths, priests, calendars etc.). The central themes of the e-book are the religious status of the emperor embedded in the Cypriot religious milieu, political relationships between Cyprus and the Empire and their influences on the imperial cult performed on the island, and the part played by imperial representation in the life cycle of the Cypriots. The appendix catalogues the relevant inscriptions, with translations and other related information.


The distributed control system (DCS) tends to become more intelligent and more professional. A three-tiers model based on multi-agent system for DCS is proposed. The function of each tier is defined, The structure of the agents in each tier is discussed and the mechanism of communication and cooperation among agents are presented. According to the model, an actual application has been developed, and the running of the application proves the model is reliable and effective.


English,French and Chinese all have the same basic sentence structure,that is to say,the same order of subject,predicative and object,but the position of negative in their sentences are different in many respects,which express different meanings.Through contrastive analysis study on position of negative in sentences of the three languages,both teacher and students can teach and learn English and French much better by using their native language or inter-language appropriately,thus improve translation and understanding between English and Chinese,French and Chinese.


18 19 Isokinetic and functional jump tests are frequently performed for assessing physical qualities 20 of soccer players during preseason. The purpose of this investigation was to explore, in an 21 elite soccer players population, the relationships between isokinetic strength and functional 22 jump performances. Thirty-eight professional soccer players were evaluated as follows: 23 isokinetic knee assessment in concentric (CON) mode (60, 240°/s) for quadriceps and 24 hamstrings, and in eccentric (ECC) mode for the hamstrings only (30°/s); one-leg hop tests for 25 distance (single hop (SH), triple hop (TH) and triple crossover hop (TCH)); one-leg vertical 26 jump tests (counter movement jump, drop jump). Players with a low bodyweight normalised 27 (BWN) quadriceps (Q) strength (<2.71 Nm/kg) performed, for a majority of the measured 28 variables, significant reduced jump performances compared to the players with high BWN Q 29 strength (>3.14 Nm/kg; p<0.05). Greater bilateral differences between uninjured and past 30 injured lower limbs were found with isokinetics (Q CON 60°/s (mean bilateral difference 31 (MBD): 10.3%; p<0.01), Q CON 240°/s (MBD: 9.9%; p<0.05), H ECC 30°/s (MBD: 16.1%; 32 p<0.001) than with functional tests (MBD: 2 to 9%; p>0.05. In conclusion, due to their 33 complementary role and implications for performance, functional and isokinetic tests should 34 be associated in a preseason soccer players assessment. 35 36


Existing solutions proposed to meet the new mercury limits under the National Emission Standard for Hazardous Air Pollutants (NESHAP) all suffer certain shortcomings, particularly for those plants that need to achieve a significant level of mercury reduction. A new mercury control system discussed in this paper overcomes these through a simple, passive, and non-invasive fixed sorbent bed approach. Both field tests and lab tests indicate the new technology is able to achieve long lifetimes in the field before requiring replacement or regeneration, an issue that has limited other fixed bed approaches from succeeding. Furthermore, this approach does not impact the final clinker or the cement kiln dust, and does not require complex on-site chemical processes to operate. These factors make it a highly cost competitive option for achieving compliance.


A procedure is developed for evaluating the hydromagnetic-instability growth rates of a fixed boundary plasma. The procedure is based on the energy principle. Three components of a plasma displacement are treated as independent variables and are expanded in terms of complete systems of functions. The potential-energy change δ W and the kinetic energy δ K are expressed as quadratic forms of the expansion coefficients. The growth rates are obtained by minimizing δ W /δ K with respect to the expansion coefficients. As an example of application, the growth rates of the Bennett pinch are evaluated for incompressible displacements. Results show that the expansion with only 3 or 4 terms for each variable gives satisfactory values of growth rates.


Expertise refers to outstanding skill or ability in a particular domain. In the domain of emotion, expertise refers to the observation that some people are better at a range of competencies related to understanding and experiencing emotions, and these competencies may help them lead healthier lives. These individual differences are represented by a wide variety of psychological constructs, including emotional awareness, emotional clarity, emotional complexity, emotional granularity, and emotional intelligence. These constructs derive from different theoretical perspectives, highlight different competencies, and are operationalized and measured in different ways. The full set of relationships between these constructs has not yet been considered, hindering scientific progress and the translation of these findings to aid mental and physical well-being. In this paper, we use a scoping review procedure to integrate these constructs within a shared conceptual space. Using domain-general accounts of expertise as a guide, we build a unifying framework for expertise in emotion and apply this to constructs that describe how people understand and experience their own emotions. Our approach offers opportunities to identify potential underlying mechanisms of expertise in emotion, thereby encouraging future research on those mechanisms as well as on educational or clinical interventions.


In the last years, important advancements have been made in implementing high resolution imaging related information inside the global management algorithm in RA patients. Musculoskeletal ultrasound has already proven its utility in visualizing directly the joint synovial tissue, the synovial vascularization and in monitoring the response to therapy. Recently, much attention has been given to the presence of tenosynovitis, as a constant, complementary but different facet of the inflammatory involvement in RA. Tenosynovitis identification in early RA stages may allow adequate treatment adjustment in early and established disease in order to prevent and/ or slow down the development of structural damage at tendon and joint level.

T he appreciation for aesthetics is a cultural universal (Dutton 2002), and the power of aesthetics and design in marketing is well established. Numerous research articles identify the aesthetic features and design elements of products and servicescapes that create consumer value and enhance customer experience. We know that aesthetics serves as a powerful tool that allows marketers to shape choice, engender loyalty, foster brand attachment, generate positive word of mouth, and promote greater willingness to pay premium prices. Interestingly, despite its universal appeal and potency as a marketing tool, one aspect of aesthetics that has yet to be fully appreciated is the power of aesthetics to do good for individuals and communities. When we embarked on this editorial journey, we aimed to merge the study of everyday consumer aesthetics with that of transformative consumer research "to explore our current understanding of the transformational power of everyday consumer aesthetics and to push the frontier of aesthetics research by highlighting new findings and directions for future research and practice" (from our call for papers). In short, we sought to publish a set of papers that demonstrate the impact of everyday consumer aesthetics on consumer and societal well-being. We are pleased to deliver on this promise. What you hold in your hands (or at your fingertips as it were) is a curated selection of articles bringing together a diverse set of aesthetic and design elements that transform something essential about consumer, or community, response. In our role as editors, we were influenced by two primary ideas. First, we were inspired by the 17 Sustainable Development Goals for 2030 set by the United Nations, which aim to tackle environmental and social issues ranging from the eradication of poverty and reduction of food waste to sustainable consumption and production patterns (United Nations Economic and Social Council 2016). We are pleased


The Coulomb interaction between a heavy fast charged particle and anelectron bound by a harmonic force has been evaluated accurately up to thesecond-order term in the Born series. The resulting mean energy transfer isgiven as a function of impact parameter, projectile velocity, and the resonancefrequency of the oscillator. Integration over the impact parameter yields thestopping cross section up to third order in the projectile charge/ital e//sub 1/ without introduction of an adjustable cutoff radius. Unlikeprevious treatments, the validity of the evaluation of the stopping crosssection within the given physical model is not restricted to the high-speedlimit. Numerical results cover the velocity range0.1less than or equal to2/ital mv//sup 2///h bar/..omega..less than or equal to20. We find a significant/ital e//sub 1//sup 3/ (or Barkas) correction in the mean energy transfer atall impact parameters. The classical Barkas correction, as given for theharmonic oscillator in the high-speed limit by Ashley, Ritchie, and Brandt(Phys. Rev. B 5, 2393 (1972)), approaches the quantal result forlarge impact parameters, but the approach is slow in the velocity rangecovered, and large discrepancies are observed in the range of impact parametersthat determine the stopping cross section. Stopping cross sections for protonson atomic hydrogen and helium have been estimated roughly bymore » assigning a singleresonance frequency to the target atom. The results cover a velocity range downto somewhat below the stopping maximum where the Barkas correction turns out tobe large. This indicates that a properly executed Barkas correction plays animportant role in the prediction of the height and the position of the stoppingmaximum.« less


Data clustering has been discussed extensively, but almost all known conventional clustering algorithms tend to break down in high dimensional spaces because of the inherent sparsity of the data points. Existing subspace clustering algorithms for handling high-dimensional data focus on numerical dimensions. In this paper, we designed an iterative algorithm called SUBCAD for clustering high dimensional categorical data sets, based on the minimization of an objective function for clustering. We deduced some cluster memberships changing rules using the objective function. We also designed an objective function to determine the subspace associated with each cluster. We proved various properties of this objective function that are essential for us to design a fast algorithm to find the subspace associated with each cluster. Finally, we carried out some experiments to show the effectiveness of the proposed method and the algorithm.


To research chemical formation of the nitrogenous polymeric metal complex, this paper studies the catalysis of the polymeric metal complex in chemical reaction via the organic combination reaction. In this paper, a series of N-functionalized nitrogenous polystyrene ligands are prepared by making chloromethylate polystyrene resin (CPS) reacting with ethanol amine, 2-mercapto ethylamine (MEA), 8-hydroxyquinoline, anthranilic acid and imidogen oxalic acid (IDA) respectively, and crosslinked polyacrylamide is obtained by adopting solution polymerization and reversed phase suspension polymerization methods. Moreover, the polymeric metal complex is obtained by making nitrogenous polymer acting on the water solutions of FeCl3, 6H2O, CuCl2, 2H2O, CoCl2, 6H2O, NiCl2 and 6H2O at certain pH and temperature, the characteristics of nitrogenous polymeric ligand and nitrogenous polymeric metal complex are presented by adopting elemental analysis, Fourier transform infrared, atomic absorption, thermogravimetric analysis (TGA) and electron spin resonance (ESR) etc., and catalytic performance of the nitrogenous polymeric metal complex on acetal (ketone) reaction and alcohol oxidation is inspected. The results indicate that polymeric metal complex can be really formed by making functionalized polystyrene acting on transition metal salt in certain conditions, and various N-functionalized nitrogenous polystyrene ligands have selectivity to the adsorption of metal ions.
