The ARGO-YBJ detector layout (a full coverage Resistive Pla te Chamber, RPC, carpet), features (high resolution space-time pixels) and location (about 60 0g/cm2 of atmospheric depth) offer a unique opportunity for a detailed study of several characteristic s of the hadronic component of the cosmic ray flux in the 1012-1015eV energy range. The analog readout of the RPC signals indeed provides a powerful tool to study, with unprecedented resolution and without saturati on, he extensive air shower space-time structure very close to its axis. The distribution of charged particles at g round and the time structure of the shower front allow estimating the shower age at the detection level independen tly from the primary mass. Furthermore the truncated size, measured within few meters from the core, gives a relia bl energy measurement without biases introduced by finite detector effects. Fluctuations are also reduced th anks to the proximity of the shower maximum to the high altitude detection level. These features allows mass c omposition studies with an EAS detector in an energy region where a comparison with space or balloon born experim ents are now possible for the first time, thus giving a further cross checks on the systematics of the adopted anal ysis procedures. Moreover, measurements of the proton-air cross section, of the particle distribution clo se to the shower axis, etc., give new inputs, in the very forward region, to the hadronic interaction models current ly used for the study of the cosmic ray flux and its origin up to the highest energies.


This lecture is a curatorial performance, a presentation of curates and texts to perform research rather than its outcome. As a performative presentation this intervention invites a rhetoric of politics, understood as the governance of interaction and living together, from a being according to to the as a being according to the formless and the between. And it explores the condition of material and subjectivity in the fluid capacity of sound as a collaborative sphere: as a co-inhabited cosmos in which we inter-relate with other things and other subjects as things, creating a shared planet that has no solid surface but a depth to sink in to.
Here we sound in raptures a sonic possible worlds whose boundaries are ephemeral, whose politics is groundless, and whose materiality is the responsibility of a generative encounter.

This presentation Responds to and performs ideas articulated in The Political Possibility of Sound: Fragments of Listening by Salome Voegelin, Bloomsbury 2019.


The sample digestion with H2O2-HNO3 as oxidant and using the microwave-heating technique was applied to the analysis of water sample for its total phosphorus content. The parameters of the microwave heating and the suitable amount of H2O2-HNO3 to be used were optimized by the orthogonal experimental design method. The total phosphorus in water after its complete oxidation to the orthophosphate state, was determined by the heterophosphomolybdate blue-photometric method. Average RSD of the method was 3. 3 %, and average recovery was 100.3%.


Objective To evaluate resting heart rate as an independent predictor of cardiovascular risk in women. Design Prospective cohort study. Setting The Women's Health Initiative was undertaken at 40 research clinics in the United States. Participants 129 135 postmenopausal women. Main outcome measure Clinical cardiovascular events. Results During a mean of 7.8 (SD 1.6) years of follow up, 2281 women were identified with myocardial infarction or coronary death and 1877 with stroke. We evaluated associations between resting heart rate and cardiovascular events in Cox regression models adjusted for multiple covariates. Higher resting heart rate was independently associated with coronary events (hazard ratio 1.26, 95% confidence interval 1.11 to 1.42 for highest [>76 beats per minute] v lowest quintile [≤62 beats per minute]; P=0.001), but not with stroke. The relation between heart rate and coronary events did not differ between white women and women from other ethnic groups (P for interaction=0.45) or between women with and without diabetes (P for interaction=0.31), but it was stronger in women aged 50-64 at baseline than in those aged 65-79 (P for interaction=0.009). Conclusion Resting heart rate, a low tech and inexpensive measure of autonomic tone, independently predicts myocardial infarction or coronary death, but not stroke, in women. Trial registration ClinicalTrials.gov NCT00000611.


Using experimental data previously obtained an attempt is made to describe some angular distribution of the protons by means of the distorted wave theory with nonlocal wave functions. A variational analysis of the excitation functions is described and the average width of the levels of /sup 32/P in the excitation range from 14.5 to 15.5 MeV is determined. A comparison is made of the excitation functions averaged to DELTA E = 800 keV and the angular distribution with corresponding magnitudes which aie represented in the form sigma = sigma /sub pr/ + sigma /sub com/ where sigma /sub pr/ is the cro ss section of the direct interaction and sigma /sub com/ is the mean cross section of the reaction with formation of the compound nucleus. Other possible mechanisms of this reaction are discussed. (JSR)


This paper presents the results of work on the development and modification of laser methods of rapid prototyping and fabrication of individual implants and matrices for tissue engineering. A technology has been developed for shaping mineral-polymer bioactive structures, based on laser photopolymerization of a liquid mixture of polyfunctional acrylic oligomers with microparticles of hydroxyapatite. A method is proposed and developed for surface-selective laser sintering, making it possible to sinter polymeric microparticles without melting them completely, but only submelting their surface. This made it possible to obtain bioactive polymeric matrices based on bioresorbable aliphatic polyesters.


With respect to safety problem of flight dynamic control systems under faulty case,a technique of model reference robust fault-tolerant control using neural network compensation is proposed.In order to improve convergence rate of neural network as well as the performance of fault-tolerant control with disturbances,an improved neural network structure based on traditional RBF neural network is proposed,in which linear connections between input and output layers are introduced.The nearest neighbor-clustering algorithm and the adaptive C-means clustering algorithm are used to train the network,and the weights of neural network are adjusted on-line.The stability of the closed-loop system is rigorously proved.Simulation results on Boeing 747-100/200 model show that the presented scheme is effective.


To realize the suspension operation for a Permanent Magnet type Bearingless Motor(PMBLM) in the dynamic process, the torque and magnetic levitation force should be real-time controlled. Therefore, the accurate computation of the torque and magnetic levitation force is the basis for the design and control of PMBLM. However, in traditional mathematic model, they are separately calculated as two independent systems without the non-linear electromagnetic coupling considered. To cover this coupling effect, By the visual displacement approach in a related magnetic field this paper puts forward an completeintegrated mathematic model of surface mounted PMBLM with all coupling factors of the torque winding, suspension winding and rotor movement considered by the visual displacement approach in a related magnetic field,and the main parameters associated with this new model is determined by the Finite Element Analysis(FEA). Through the simulation based on this completeintegrated model, the stable suspension operation of PMBLM is well achieved with the strategy of the rotor field oriented control. Compared with the results simulated by the traditional mathematical model, the integrality and accuracy of the complete model has been thoroughly verified.


A key aspect of cooperation is the choice of partners with whom to cooperate, as this determines if an individual can establish a successful cooperative interaction and reduce the chances to be exploited. In most of the experiments on cooperation conducted so far, subjects had no opportunity to choose their cooperative partner, or the choice was reduced between two individuals. Non-human primates, however, live in complex social groups and can choose their social partner among several individuals. We presented a cooperative apparatus to a wild provisioned group of Barbary macaques, leaving them the choice to interact or not with the apparatus, and with any of their group companions. We used the same experiment used in captive studies on cooperation (Crawford, 1937), requiring two monkeys to pull a rope simultaneously in order to both get rewards. We found mixed evidence of cooperation in our study group and we discuss here the methodological and theoretical difficulties of running experiments with free-ranging animals.


A tvoday Research Symposium is held prior to the official CHI '95 conference, Saturday and Sunday May 6-7, 1995. The Symposium is for active researchers in HumanComputer Interaction. The intent of the Symposium is to provide an interactive forum to promote and enhance scientific discussions of developing research issues. The Research Sympasium is designed to complement other parts of the CHI '95 Conference, e.g., the papers program, design briefings, demonstrations, videos, panels, posters, and exhibits.


We propose to test the homogeneity of a Poisson process observed on a finite interval. In this framework, we first provide lower bounds for the uniform separation rates in $\mathbb{L}^2$ norm over classical Besov bodies and weak Besov bodies. Surprisingly, the obtained lower bounds over weak Besov bodies coincide with the minimax estimation rates over such classes. Then we construct non asymptotic and nonparametric testing procedures that are adaptive in the sense that they achieve, up to a possible logarithmic factor, the optimal uniform separation rates over various Besov bodies simultaneously. These procedures are based on model selection and thresholding methods. We finally complete our theoretical study with a Monte Carlo evaluation of the power of our tests under various alternatives.


Since 2006, baby-boomers are beginning to reach the age of 60. This historic milestone forecasts serious challenges for our societies. In particular, the financial security of future pensioners constitutes an important issue. The present study will attempt to assess the financial preparation for retirement of the Quebec first cohorts of baby boomers born in 1946- 1955, who will retire in the forthcoming years, by comparing their situation with their Ontarian counterparts. This study is composed of four distinct parts. First, the methodology of the study will be explained. After a literature review, some indicators will be selected to measure the financial preparation to retirement from three points of view. Thus, the objective health of the financial preparation to retirement will be analyzed by comparing Quebec and Ontario. The relative situation of the Quebec first cohorts of baby boomers, illustrated by their revenue, their housing status and their patrimony, will also be explained. The third part of the study tries to compare the first cohorts of baby boomers' subjective health of the preparation for retirement between the two provinces, for some socioeconomic categories, by using data concerning their satisfaction and their perspectives toward this issue. Finally, this study ends with a comparison of the various strategies used by the Quebec and Ontario first cohorts of baby boomers in order to assure themselves a suitable financial security for retirement, considering the actual trends of the socioeconomic conditions. The data analyzed come from various Statistics Canada surveys. In particular, demographic census data were used for the period covering 1971-2001, as well as the Survey of Financial Security (SFS) for 1999 and General Social Survey (GSS) for 2002.


A nonlinear mathematical model of a vacuum-based continuous casting process and an implicit nonlinear controller are developed. The aim of the controller is the regulation of the mold and tundish molten steel levels. In the proposed approach, the output error is designed to be asymptotically stable, and the current values of the control inputs are numerically determined using the Newton-Rapson iterative procedure. The dynamic performance of the closed-loop system is analyzed using computer simulations. RESUMEN


High energy scattering processes in QCD can be described in terms of interacting pomerons. Vertices for the interaction of pomerons have been derived in perturbative QCD. Their properties hint at the existence of a 2+1-dimensional conformal field theory of interacting pomerons. Here we study in particular the 1-to-2 and the 1-to-3 pomeron vertex and find them to be related to each other by a conformal bootstrap relation.


We present an open wavefront sensor setup assisted with MATLAB programming to be used to teach the operating principle of Shack–Hartmann aberrometry. A new Graphical User Interface (GUI) has also been developed to determine the wavefront parameters from experimental measurements and the associated aberrations, which is a fundamental issue in Optical Engineering. From a didactical point of view, the proposed method allows students to interpret the results in a visual and heuristic way. © 2015 Wiley Periodicals, Inc.

The aim of this research was to determine the effects of physical activity levels of teacher candidates on the sub-dimensions of health-related quality of life. In the research among the quantitative research methods, relational survey model was used. A total of 90 teacher candidates participated in this research. The International Physical Activity Questionnaire-Short Form (IPAQ-SF) and the 36-Item Short Form Health Survey (SF-36) were used in this study. In the data analysis, "percentage, frequencies, standard deviation, mean, Product-Moment Correlation coefficients and Multiple regression" were used. According to the results, role functioning/emotional, pain and general health sub-dimensions are important predictors on physical activity levels. However, physical functioning, emotional well-being, vitality, social functioning, role functioning/physical, sub-dimensions have not an important impact on physical activity levels statistically. As a conclusion, participation in physical activity can be said to have a negative effect on emotional problems and pain, and a positive effect on general health status.


In this paper, we consider a general form of self-dual equations arising from Abelian gauge field theories coupled with the Einstein equations. By applying the super/subsolution method, we prove that topological multi-string solutions exist for any coupling constant, which improves previously known results. We provide two examples for application: the self-dual Einstein-Maxwell-Higgs model and the gravitational Maxwell gauged O(3) sigma model.


We consider the quality of a process which can be characterized by a general linear profile where the random error has a contaminated normal distribution. On the basis of trimmed least squares estimation, new control charts for monitoring the coefficient parameters and/or the error variance of the profile are proposed. Simulation studies show that the proposed control charts outperform the existing competitors under such a profile. An example from manufacturing facility is used to illustrate the applicability of the proposed charts. Copyright © 2013 John Wiley & Sons, Ltd.


ABSTRACT Background The impact of genetic variation in the thiopurine S-methyltransferase (TPMT) gene on thiopurine-induced leukopenia has been well demonstrated. Although xanthine dehydrogenase (XDH) is the second major contributor to azathioprine breakdown, polymorphisms in XDH have rarely been studied in IBD patients. We aim to access association between XDH variants and thiopurine-induced leukopenia by gene–gene interaction in a Crohn's disease (CD) population. Study A total of 964 CD patients treated with thiopurines were recruited from a tertiary referral center. The association between four XDH variants (p.Gly172Arg, p.Asn1109Thr, p.Arg149Cys, and p.Thr910Lys) and thiopurine-induced leukopenia was analyzed in cases with early leukopenia (n = 66), late leukopenia (n = 264), and in controls without leukopenia (n = 632). Three non-synonymous SNPs, which we previously reported association with thiopurine-induced leukopenia, NUDT15 (p.Arg139Cys), SUCLA2 (p.Ser199Thr), and TPMT *3C were selected for epistasis analysis with the XDH variants. Results There was no significant association for two variants of XDH and thiopurine-induced leukopenia. In the epistasis analysis, only XDH (p.Asn1109Thr) * SUCLA2 (p.Ser199Thr) showed a statistically significant association with early leukopenia [odds ratio (OR) = 0.16; p = 0.03]. After genotype stratification, a positive association on the background of SUCLA2 wild-type (199Ser) between the XDH (p.Asn1109Thr) and early leukopenia (OR = 4.39; p = 0.01) was detected. Conclusion Genes associated with thiopurine-induced leukopenia can act in a complex interactive manner. Further studies are warranted to explore the mechanisms underlying the effects of the combination of XDH (p.Asn1109Thr) and SUCLA2 (199Ser) on thiopurine-induced leukopenia.


Using Regular Path Queries (RPQs) is a common way to explore patterns in graph databases. Traditional automata-based approaches for evaluating RPQs on large graphs are restricted in the graph size and/or highly complex queries, which causes a high evaluation cost. Recently, the threshold rare label based approach applied on large graphs has been proved to be effective. Nevertheless, using rare labels in a graph provides only coarse information which could not always guarantee the minimum searching cost. Hence, the Unit-Subquery Cost Matrix (USCM) based approach has been proposed to reduce the parallel evaluation cost by estimating the searching cost of RPQs. However, the previous approach does not take the joining cost among subqueries into account. In this paper, the method of estimating joining cost of subqueries is proposed in order to accelerate the USCM based parallel evaluation of RPQs. Specifically, the proposed method is realized by estimating the result size of the subqueries. Through our experiments upon real-world datasets, it is depicted that estimating joining cost enhances USCM based approach up to around 20% in terms of response time.


ABSTRACT The increasing discomfort with ethnic diversity in many countries is paralleled by the emergence of middle classes consisting of second-generation immigrants who articulate their minority identities. This calls for an enhanced understanding of the experiences and identifications of social climbers with minority backgrounds. In this article, I explore the relevance of the idea of a "minority culture of mobility" (MCM) as a lens to look at these processes of integration, using the case of Dutch student organizations with ethnic-minority signatures. Based on parallels with the literature, I conclude that the MCM is a useful framework, also for contexts outside the United States. At the same time, observed variations between ethnic groups and changes over time within the Dutch context lay down a research agenda in order to further refine the model.


Based on the deflection control of concrete beam,smart prestress in beams is introduced to change the value of prestress in beams under different live loads.That is to say,according to the live load on a beam,the deflection of smart prestressed beam can be controlled in the design range if the beam is collocated with a suitable smart anchor,which can change the value of prestress in the smart beam by means of propping up or drawing back the smart anchor.The deflection of an unbonded smart prestressed simply supported beam,which regards midspan deflection as its control target,is analyzed to deduce the control differential equation of structure under moving load.A numerical example is adopted to show the whole functioning process of prestress in the smart beam and explain the feasibility of smart prestress control theory.


The noise transfer characteristics in an electro-absorption modulator are investigated. The transfer of intensity noise is assessed by considering the optical signal-to-noise ratio and relative intensity noise of the optical signals. An electro-absorption (EA) modulator is described from the viewpoint of noise transfer characteristics, where input optical signals are converted to electrical signals and the EA modulator is driven by the inversely amplified electrical signals. We have analyzed the linearity performance of analog fiber-optic links based on electro-absorption modulators (EAM) operating at high optical power. At substantially high optical power noise increases.


"The Law on Radiation Safety of the Population" and regulations for individual radiation-dosimetry monitoring suppose separate registration of background and technogenic exposure components. Background and technogenic radiation levels are comparable in the conditions of accident-free work of the personnel of group B and for the population. If their measurements are made by the same type of devices, there is a computational problem of background subtraction, which is usually solved by arithmetic methods, or even ignored. This leads to a known paradoxical bias of dosimetric information, allowing the existence of negative dose estimates or negative activities. The way allowing to overcome this paradox is considered in the publication.


Soft composite solids are made of inclusions dispersed within soft matrices. They are ubiquitous in nature and form the basis of many biological tissues. In the field of materials science, synthetic soft composites are promising candidates for building various engineering devices due to their highly programmable features. However, when the volume fraction of the inclusions increases, predicting the mechanical properties of these materials poses a significant challenge for the classical theories of composite mechanics. The difficulty arises from the inherently disordered, multi-scale interactions between the inclusions and the matrix. To address this challenge, we systematically investigated the mechanics of densely filled soft elastomers containing stiff microspheres. We experimentally demonstrated how the strain-stiffening response of the soft composites is governed by the critical scalings in the vicinity of a shear-jamming transition of the included particles. The proposed criticality framework quantitatively connects the overall mechanics of a soft composite with the elasticity of the matrix and the particles, and captures the diverse mechanical responses observed across a wide range of material parameters. The findings uncover a novel design paradigm of composite mechanics that relies on engineering the jamming properties of the embedded inclusions.


a hardware-efficient hybrid greedy CU (coding unit) partition algorithm for AVS3 intra prediction, which has advantages over the traditional regression algorithm on both scheduling complexity and resource consumption, is presented. Compared with the NVidia hardware acceleration of HEVC, the proposed algorithm achieves 21% performance improvement on AI (all-intra) configuration for UHD 4K video encoding.


Stability of state delay systems is discussed by investigating properties of a Lyapunov functional. Firstly finite characterization of a Lyapunov functional equation for state delay systems is proposed. The finite characterization can be computed using a matrix exponential function, while conventional computation has been relied on numerical approximations. Secondly based on the finite characterization, a stability condition for state delay systems with unknown but bounded constant delay is proposed.


(196–7). Reducing social distance for the purpose of improvement is demonstrated in a study in which a small photograph of human eyes increased the amount people place in an honesty box (199). A similar improvement is seen when social distance is lowered by placing people in groups – even when the grouping is known to be arbitrary – and generosity within the group increases (201). While Alfano concludes that face-to-face engagement should be encouraged as a moral technology, this is uncontroversial and no specific strategy is outlined. The other moral technology, however, is both clearly outlined and more controversial. While it might raise eyebrows amongst those who doubt that virtue ethics can really be served by advocating dishonesty, Alfano is consistent: he is offering a naturalistic ethic that follows norms, and so he has no a priori commitment to truth-telling. However, therein lies a different inconsistency: he is committed to normativity, but surely the kind of moral technology he advocates represents as abstract imposition? If, however, Alfano wished to delve into the area of moral technology then a better approach might have been to explore some of the practices of socially-reinforcing virtue that already exist. The result could be the endorsement of practices with the level of empirical support from which his thesis concerning the nature of character benefits. He could continue in the same vein to search for empirical support from social psychologists, though the insights of social anthropologists might be useful in identifying such practices. Given the lengths to which Alfano goes in providing an empirical foundation for his understanding of factitious virtue, it is disappointing that he does not present a similar foundation for the moral technology that he advocates.

THE NOTION of the Army as a profession is as old as the Army itself, but the belief that soldiering is a profession is no longer commonplace for those in uniform. Much discussion in the Army today concerns what it means to be a professional soldier, but the profession itself is losing its status, and no one in the Army is talking about that. In this respect, the Army is like an ostrich with its head in the sand, while it should be like the phoenix continually renewing itself. Army doctrine explains leadership in terms of a "be-know-do" philosophy, but it does not tell officers and soldiers how to be military professionals. In fact, Field Manual 22-100, Army Leadership, Be, Know, Do, the capstone leadership manual, does not mention the word profession. (1) The Army describes itself as "an institution, not an occupation." (2) The only mention of professionalism in Army regulations (ARs) is in AR 623-105, The Officer Evaluation Reporting System, which says, "Part IV [of the Officer Evaluation Report Form] contains a listing of the Army Values and the dimensions of the Army's leadership doctrine that define professionalism for the Army officer." (3) But the list of attributes is not a specific checklist that would help individuals within the profession understand what it means to be professionals. The omission of a useful description of what the Army considers professionalism might be a root cause of the current confusion about professional obligations and responsibilities. In The Future of the Army Profession, Don M. Snider examines results from the Army's Training and Leadership Development Panel, compares the Army with other professions, discusses the need for the military to advise civilian leaders, and postulates that the Army is in a period of growing uncertainty about the nature of military professionalism. (4) That uncertainty threatens to relegate the Army to the level of just another government agency or bureaucracy with no bona fide professional status. Snider's study is remarkable because, essentially, it is the only contemporary discussion on the subject. Any search for opinions or contrasting viewpoints yields little fruit. Before 1990, no ongoing Army studies of professionalism had occurred at the institutional level since the 1970s. (5) In the last 10 years, Snider's work has stood alone in addressing Army professionalism. He has written nearly all the published essays and articles on the subject, and others writing on the subject base their work on his. Still, no new discussion on the subject of professionalism addresses the profession's future. This is a troubling and potentially dangerous state of affairs. Theory of Professionalism Snider agrees with sociologist Andrew Abbot that a profession possesses three attributes: expertise, jurisdiction, and legitimacy. (6) Samuel Huntington also identifies expertise, corporateness, and responsibility as characteristics of professionalism. Former Army Lieutenant Colonel Sam Sakesian identifies special knowledge and education; organizational structure; self-regulation; and "commitment and calling"--the latter implying a degree of service to society at large. (7) I refer to Snider's tenets---expertise, jurisdiction, and legitimacy--to discuss two types of professionalism: theoretical and practical. I see these tenets as being the theoretical components of professionalism because they describe the ideal but do not prescribe the means to attain it. I define the practical components of professionalism as organization and return on investment (or giving back to the institution). These are the practical ways for the profession to ensure its survival and future growth. Expertise. Professional expertise refers to the body of knowledge that the profession's members have mastered--a body of knowledge that is not common in society at large because those outside of the profession typically do not acquire it. Just as a doctor's expertise is the study and practice of medicine, the Army professional's expertise is the study and application of military science. …


Since the advent of Internet technology, the computing environment in many applications has been changed drastically. Especially, the e-Logistics is the virtual logistics business activity and service architecture among the companies based on the Internet technology. To construct effectively the e-Logistics framework, several advanced technologies such as GPS, GIS, ITS with moving objects technique are required. Although these advanced technologies have a lot of characteristics that enable support of new services as well as reduce the cost of transportation of logistics, they also have common things that must be resolved in terms of efficiency and effectiveness of moving objects management. The weakness of these techniques is that they always consider only the information that is valid at the current time, and hard to manage the past and future information. To overcome this problem, the researches on moving objects management system (MOMS) have been started from a few years ago. The moving objects management system consists of 4 layers; integrated location data interface, moving object engine, location-based knowledge manager and web/mobile presentation interface. Especially the moving object engine is the core module of MOMS, and it supports store and query technique about moving object data efficiently. Keywords-GIS, moving object, query language


In designing equipment such as heat exchangers, heating and cooling systems, it is of great importance to provide higher convective heat transfer coefficients. Techniques aimed at enhancing heat transfer can increase the thermal efficiency of such industrial devices while minimizing the cost and size. One of the solutions specified for this problem is the utilization of nanomaterials. To prepare nanofluids, nanoparticles are dispersed in an appropriate base solution which forms a suspension [1] to [3]. The initial works on the formation of nanofluids were concentrated on using metal and metal oxide nanomaterials [4]. In this respective, Heris et al. [5] researched the effect of using Al2O3/water nanofluid on convective heat transfer from which it was found that by adopting 2.5 vol.% to 3 vol.% nanoparticles, the maximum increment of heat transfer is acquired. In another research, Patel et al. [6] showed that when a mixture of 11 % Au and Ag nanoparticles are used, thermal conductivity is augmented by about 21 %. Moreover, as reported by Zarringhalam et al. [7], by using CuO/water nanofluid in forced turbulent convection in two uniaxial tubes, heat transfer is increased by up to 57 % for the sample containing 2 vol.% nanoparticles. In addition, in some relative reviews [8] to [10], thermophysical properties of different nanofluids were compared and discussed, and the effect of each nanofluid on heat transfer capability of the industrial equipment was studied. In different studies, convective heat transfer of various nanofluids has been investigated in laminar [11] and [12] and turbulent [13] flow regimes. After using the metal and metal oxides, researchers started to use carbonaceous nanomaterials, which possessed higher thermal conductivity [14] and [15]. Among these efforts, Amrollahi et al. assessed the effect of multiwall carbon nanotubes on the convective heat transfer coefficient in laminar and turbulent flows [16]. For 0.1 wt.% nanoporous graphene in a circular tube, 34 % increment of convective heat transfer was obtained by Naghash et al. [17] in which the laminar flow regime was considered. Moreover, Amiri et al. [18] studied the thermophysical properties of the nanofluid prepared with functionalized graphene. They showed that the ethylene glycol-functionalized graphene in the mixed solution of water and ethylene glycol, the thermal conductivity was enhanced by Experimental Assessment of Turbulence Convective Heat Transfer and Pressure Drop in Annuli using Nanoporous Graphene Non-Newtonian Nanofluid Ghanbari, S. – Javaherdeh, K.

To find out the reason for the sudden rise of the oxidation temperature in coal spontaneous combustion process,and provide theoretical basis for the prevention and control of spontaneous com-bustion in coal mines,the adiabatic testing method and programmed temperature rising method were used in this paper,to study the temperature rising,oxygen consumption,gas production(CO and CO2) characteristics of lignite in Baizao coal mine during the oxidation process.It is indicated that the oxida-tion of lignite has the subsection characteristic,and can be divided into two stages,that is,slow oxida-tion process during the low temperature and fast oxidation during the high temperature.The functional groups variation law during the whole oxidation process was tested by in-situ FTIR.The results show that the reaction of OH leads to the subsection characteristic of lignite during oxidation process,and the endothermic reaction of OH is the main reason why the heat is difficult to accumulate in the low tem-perature stage.Once OH is depleted,heat begins to accumulate and the temperature of coal rises imme-diately.


A new closed-form expression of the spectral coefficients of the digital streams obtained by dyadic digital pulse modulation is presented and validated in this letter. The new expression provides in-depth insight into the spectral properties of dyadic digital pulse modulation, revealing its applicability as an all-digital bandpass amplitude modu- lation technique. Simulations and measurements on a proof-of-concept dyadic digital pulse modulation amplitude modulator prototype demon- strate the effectiveness of the approach.

Mass production processes are generally sources of variability on the geometry of the product. A probabilistic approach is one way to take into account this varia bility and to evaluate its effect on the performances of the prod uct. In this communication, we apply this approach to study the ffect of the variability on dimensions of the stator on the perf ormances of an electrical machine.


Numerical simulations examining chemical interac-tions of water molecules with forsterite grains havedemonstrated the efficacy of nebular gas adsorptionas a viable mechanism for water delivery to theterrestrial planets. Nevertheless, a comprehensivepicture detailing the water-adsorption mechanismson forsterite is not yet available. Towards thisend, using accurate first-principles density functionaltheory, we examine the adsorption mechanisms ofwater on the (001), (100), (010) and (110) surfacesof forsterite. While dissociative adsorption is foundto be the most energetically favourable process,two stable associative adsorption configurations arealso identified. In dual-site adsorption, the watermolecule interacts strongly with surface magnesiumand oxygen atoms, whereas single-site adsorptionoccurs only through the interaction with a surface Mgatom. This results in dual-site adsorption being morestable than single-site adsorption.

artworks carried out a suggestion of how the belief system on consumer lifestyle had been projected and developed. The concept of Urban and Shopping Malls, and the concept of Materialism within Consumerism were used to contextualised the research project. A studio practice method was used through studio experimentation, selfreflection, critique sessions, and contextual review approaches. The research project's contribution to the field of Fine Art has been to establish the collective issues of new culture of status, leisure and social relationship as new symbolic forms of representation
of meaning in shopping malls. The research project contributed in correlating of how shopping malls could become as a continuous changing incubator in producing and shaping current urban trending enthusiastic and culture behavior of desire, satisfaction and expression. Furthermore it would become as a suggestion for new perspective on mind set towards urban culture lifestyle and turn as new culture of desire and satisfaction in everyday life experience.


The article claims that there is no substitution of labour for creative work in modern economics. The products of creative work participate in commodity circulation on equal grounds with common labor. That is why there is no value "destruction" taking place in reality.


Chitosan is a natural material that can be obtained from fishery waste
such as crustacean shells and squid pens obtained from squid. Squid pen is a waste
produced from the processing of squid with transparent structures with feather-like
shapes attached to the dorsal inside a squid mantle. Chitosan from squid pen has
been developed in the medical field because it has biocompatible properties,
biodegradable, non toxic, and also has antifungal activity. Being able to eliminate the
Candida albicans fungi which is a predisposing factor for the occurrence of denture
stomatitis due to the use of long-term dentures. Purpose: This study aims to
determine the antifungal activity of chitosan extracted from squid pen against
Candida albicans. Methods: Candida albicans was planted in Saboraud broth liquid
media tubes and given chitosan suspension 1.5% (w/v) with each sample group
consisting of 50%, 25%, 12.5%, 6.25%, 3.125%, 1.56%, 0.78% and there are two
control groups namely positive and negative controls. All samples were incubated for
24 hours at 37℃. Then a visual observation of turbidity on liquid Saboraud broth
media was then carried out by planting culture on SDA media with 7 replications,
incubated for 2x24 hours at 37 ℃ and counted the number of living colonies. The
results were analyzed using Kruskall Wallis and Post hoc tukey test. Result: At the
concentration of 25% there was no fungal growth in saboraud dextrose agar media.
Conclusion: Chitosan that extracted from squid pens has antifungal activity against
Candida albicans fungi with minimal concentration 25%.


Forward error correction (FEC) techniques are applied to INTELSAT intermediate data rate (IDR) services to reduce the transmitted power requirements relative to uncoded systems, thereby increasing the satellite transponder capacity. Properly designed FEC systems reduce data errors in the received digital stream with minimal impact to the protocols, operation and equipment involved with the communication system. This paper discusses the overall system impact of the addition of FEC to the IDR service. The appropriateness of the specific application of convolutional encoding combined with Viterbi decoding techniques is discussed. Basic concepts of convolutional encoding and Viterbi decoding are presented in order to provide understanding of the trade-offs involved in the specification of the coding technique for the IDR service. The details of the IDR FEC specification are presented. The implementation of a system based on a VLSI Viterbi decoder device which conforms to the INTELSAT requirements is described.


The higher costs of hot-mix asphalt pavement are causing more agencies to choose pavement preservation techniques to maintain their pavements. Some agencies have experienced stripping of the asphalt surface under chip seals, this distress appears to occur mostly in urban areas on curb and gutter streets. The main objective of the study was to determine what causes the stripping and to develop test methods to determine if the street will strip prior to placement of the chip seal. Both field and lab methods were used. Research focused on determining air voids, permeability, and density of the samples. Once these were determined, correlations were developed to determine the conclusions.


Supplemental Digital Content is Available in the Text. Background and Objectives: Drug name confusion induced by look-alike drug names represents a serious health care management problem in practice. Text enhancement by changing visual attributes of look-alike drug names has been proposed and widely applied in practice to mitigate drug name confusion. However, the effectiveness of text enhancement on reducing drug name confusion is yet to be determined. This study aimed to explore the effects of text enhancement on reduction of confusion caused by look-alike drug names through systematic review and meta-analysis. Methods: We searched 5 databases (from database inception to January 2020) for empirical studies that examined the effects of text enhancement on reduction of look-alike drug name–induced drug name confusion. The pooled outcome data were analyzed using either meta-analysis or a narrative synthesis approach. Results: From the 351 identified articles, 11 articles representing 20 individual trials were included. Five basic text enhancement methods were revealed, including Tall Man, red, boldface, contrast, and size enhancement, from which 4 Tall Man variants and 6 text enhancement combinations were derived. The meta-analysis results showed significant reduction in omission errors when using Tall Man (standardized mean difference [SMD] = −0.628, 95% confidence interval [CI]: −1.018 to −0.238, P = .002), red (SMD = −0.516, 95% CI: −1.002 to −0.030, P = .038), boldface (SMD = −1.027, 95% CI: −1.240 to −0.814, P < .001), and contrast (SMD = −0.437, 95% CI: −0.869 to −0.004, P = 0.048), as compared with lowercase. This finding was also supported in our subgroup analysis by task type for name differentiation tasks. No other significant effects of text enhancement were found for either commission errors or response time. Conclusions: Using Tall Man, red, boldface, or contrast could help reduce omission errors (ie, wrong medication selection) caused by look-alike drug names, particularly in name differentiation tasks. However, no text enhancement could shorten name search and/or differentiation time. Our findings could facilitate the understanding of the effects of text enhancement in the prevention of confusion errors caused by look-alike drug names and promote the application of text enhancement in practice.

This article addresses contemporary aspects of labor and consumption through the lens of social psychology. Following what I call "new social organization of illusion", this paper seeks to understand the corresponding new organization of production and the subjective implications of this new social-production configuration. Through the concept of fetishism (used both in the social and psychoanalytic thought), I discuss the shift from "labor-value" to "experience-value" that takes place in new business configurations which market "experiences" instead of products. This shift also drastically changes "fetish" as a theoretical concept and the subjective ways of dealing with the issue.

Purpose of review Polysubstance use is very common in the world, but there has been limited research in this area. South Asia is sandwiched between two of the world's largest heroin producing areas: the Golden Crescent and the Golden Triangle. The burden and prevalence of polysubstance use have not been estimated in this region of the world. We review the research findings on polysubstance use in different South Asian countries. The review also comments on the gaps in knowledge regarding polysubstance use in this region of the world. Recent findings The available literature on polysubstance use from South Asia suggests its widespread presence in the region, ranging from 20 to 90%, more commonly among illicit opioid drug users and injection drug users. Most of the available data is from epidemiological studies. There are few studies on the adverse effects of polysubstance use, but the limited data clearly suggests an elevated risk of comorbid psychopathology and health problems. Summary Polysubstance use still lacks a consensus definition. There is a need of more research on its prevalence, effects on health, and prevention and treatment.


Abstract A new genus and species of bopyrid isopod infests the deep-water galatheid crab Munidopsis beringana collected at a depth of 4100 m off the central coast of California. The head of the female Goleathopseudione bilobatus n. gen., n. sp. is separated from the first pereiomere as in Pleurocryptella, but differs from this and Bathione in having three pairs of lamellae in the barbula and well-developed coxal plates, in the shape of the biramous sub-cylindrical pleopods, and in the absence of uropods. Goleathopseudione is morphologically similar to Pleurocryptella with respect to the absence of lateral plates, and to Bathione with respect to the unsegmented maxillipedal palp. The male of the new genus is close to Pleurocryptella as they both have a well-developed bi-articulated maxillipedal palp, and it is different from it and Bathione in having a sub-ovoid flap covering the sixth segment dorsally. Goleathopseudione is the third genus of bopyrid isopod that infests the host genus Munidopsis in the eastern Pacific, and the second described for a depth greater than 4000 m.


: Recently, the full-waveform inversion (FWI) has been widely studied due to its main advantage that it enables us to indirectly estimate subsurface parameters from surface seismic data. However, for more accurate estimation of subsurface parameters, anisotropic multi-parameter FWI should be considered because seismic anisotropy is an important physical phenomenon that significantly affects wave propagation in complex sedimentary basins. For such anisotropic full-waveform inversion, finding an optimal parameterization and an optimal FWI strategy is crucial to mitigate parameter trade-offs and to reduce the Null space. In this study, we first analyze the radiation pattern of partial derivative wavefields from each model parameter perturbations considering multi-channel streamer and ocean bottom seismometers. Based on the radiation pattern analysis, we analyze the sensitivity of each model parameter to the marine seismic data and the trade-offs between model parameters. Finally, we suggest an optimal FWI strategy to build anisotropic Earth model more correctly.

The experiment was done on a sample of 44 students of the fourth year of The Faculty of Sport and Physical Education in Belgrade with no previous rowing experience, of average age 25±2 years, average weight 81±8 kg, and average height 184±7 cm. It lasted ten weeks, three times a week (according to the program of learning basic rowing technique in summer term). Elementary rowing technique was learned in a school boat "Galija" with twelve seats on flat water. No suggestions were made to the subjects about using specific force distribution or length of stroke. Rowing machine "CONCEPT II" was used for gathering basic data (on initial and final test). Stroke parameters in real time were measured by "FITRO ROWER" instrument "WEBA SPORT", and they were processed on programme "SOFTWARE EXPERT 1.2". Thirteen different biomechanical parameters of the stroke were measured: drive time (m/s), recovery time (m/s), rhythm (%), accomplished rowing frequency (stroke/min), power average during the entire stroke cycle (W), power average during the drive time (W), power peak (W), force average during the entire stroke cycle N), force average during the drive time (N), force peak (N), handle velocity average (m/s), handle velocity peak (m/s), stroke length (cm). The test consisted of three measurements with assigned rowing frequency of 24, 28 and 32 strokes per minute. Significant change was noted in all measured variables. The biggest decrease of variation coefficient was noted on the variables of force and power. Increase in the frequency of rowing led to significant changes in all measured variables, in that way that their variation coefficient decreased. Teaching rowing technique in "Galija", its big mass and big hydrodynamic resistance of water represent disadvantages when learning duration of active and passive phase, as well as the rhythm of rowing. These disadvantages will become the advantages when the values of force and the power of stroke are learned. The results in the final measurement showed that stroke length was the variable which was learned first. The biggest progression was noted with the variables of power and force. It is proved that the frequency of rowing is the important factor in learning rowing technique. Learning should start at lower frequency, and soon change to the frequency of 32 strokes per minute. The results show that we can also discuss faults in rowing technique depending on variability of tested stroke parameters.

We investigate the photoexcitation of nucleon resonances in nuclei taking into account the quark structure of the nucleon. We calculate the total strength of the {ital M}1, {ital E}1, and {ital E}2 excitation in a two-nucleon system, considered as two three-quark clusters with a properly antisymmetrized wave function. The calculations show that the resonance excitation in the deuteron is not modified with respect to the free nucleon case. In contrast, when the nucleon relative distance assumes typical nuclear values, quark exchange leads to a {similar_to}11% damping of the {ital D}{sub 13} resonance and {similar_to}23% of the {ital F}{sub 15}, but it leaves the {Delta} excitation practically unaffected, in agreement with the recent photoabsorption measurements.

There has been significant recent work on understanding the variation of high explosive detonation phase velocity (D0) in a two-dimensional slab geometric relative to that in an axisymmetric cylindrical (ratestick) geometry having the same confinement as the slab. The ratio R(D0)/T (D0) has been termed the steady propagation scale factor by Jackson and Short [8], where R is the radius of a rate-stick that results in a given detonation phase velocity D0, while T is the corresponding thickness of a slab that result in the same detonation phase velocity. The ratio R(D0)/T (D0) varies as a function of D0. In the cylindrical rate-stick geometry, the detonation shock has two curvature components; the slab component which is the two-dimensional curvature along a diameter of the rate-stick, and the corresponding axisymmetric component. Petel et. al [9], Silvestrov et al. [10] and Higgins [6] have found a propagation scale factor R(D0)/T (D0) > 1 for the explosives studied. In contrast, Jackson and Short [7, 8] found R(D0)/T (D0) < 1 for three explosives nominally characteristic of ideal (PBX 9501), insensitive (PBX 9502) and non-ideal (ANFO) explosives. The purpose of the current work is to use a Detonation Shock Dynamics (DSD) model to give detailed insight into the dynamics behind the variation in the propagation scale factor R/T when the detonation phase velocity D0 approaches the Chapman-Jouguet velocity DCJ for different degrees of confinement. In particular, we will extend the analysis in Jackson and Short [8] for larger variations in the difference between D0 and DCJ .


We extend our recently developed algorithm for computing (exact) steady-state blocking probabilities for each class in product-form loss networks to cover general state-dependent arrival and service rates. This generalization allows us to consider, for the first time, a wide variety of buffered and unbuffered resource-sharing models with non-Poisson traffic as may arise with overflows in the context of alternative routing. As before, we consider non-complete-sharing policies involving upper-limit and guaranteed-minimum bounds for the different classes, but here we consider both bounds simultaneously. Major features of the algorithm are: dimension reduction by conditional decomposition based on special structure, an effective scaling algorithm to control errors in the inversion, the efficient treatments of multiple classes with identical parameters and the truncation of large sums.

We test the hypothesis of partially conserved axial current in high-energy diffractive neutrino production of pions. Since the pion pole contribution to the Adler relation (AR) is forbidden by conservation of the lepton current, the heavier states, like the a{sub 1} pole, {rho}-{pi} cut, etc., control the lifetime of the hadronic fluctuations of the neutrino. We evaluate the deviation from the AR in diffractive neutrino production of pions on proton and nuclear targets. At high energies, when all the relevant time scales considerably exceed the size of the target, the AR explicitly breaks down on an absorptive target, such as a heavy nucleus. In this regime, close to the black disk limit, the off-diagonal diffractive amplitudes vanish, while the diagonal one, {pi}{yields}{pi}, which enters the AR, maximizes and saturates the unitarity bound. At lower energies, in the regime of short lifetime of heavy hadronic fluctuations the AR is restored, i.e., it is not altered by the nuclear effects.


Taking into account three basic methodological principles (namely to know the Platonic love theory as it his writings, to accept the person who is responsible for the dialogue as a spokesman of that theory and to try to ascertain the systematic character ol halo's thought) the autor of the text goes through those Plato's works where he deals with Eros and tries to establish its own consistnecy and the relationship there is between Platonic Erotika and the education of young people.


The invention discloses a method for preparing a coconut-flavor boiled salted duck. The method comprises the steps of material selection, cleaning, picking, dry-salting, integral marinating, re-marinating, blank drying, cooking, quenching, drying by airing, and sterilization packaging. The method disclosed by the invention has the advantages that on the one hand, the adopted coconut powder, coconut shreds and coconut juice endow the boiled salted duck with a new flavor, and the coconut juice contains proteins, amino acids, vitamins, fats and minerals which are different with those in poultry products and contains more low carbon chain fats which are beneficial for the human body, therefore, the prepared coconut-flavor boiled salted duck meets the health consumption concept and nutrition view of the modern people; and on the other hand, the silicate mineral water is taken as raw materials and catalysts, therefore, the trophic structure of the boiled salted duck product is enriched, andas an effective flavor modified catalyst, the silicate mineral water optimizes the flavor of the boiled salted duck; meanwhile, the problem that the traditional boiled salted duck is difficult to be tasty, short in quality guarantee period and difficult to keep the flavor is solved, and the prepared boiled salted duck is delicate in taste, delicious in meat, good in flavor and high in nutritionalvalue, and has a certain health care effect.


Chlorpyrifos (CPF) is a kind of organophosphates, which extensively used in agricultural production and residential environment. Except the acute toxicity, great concern has been raised about the chronic toxicity and potential hazard. Besides, some studies have prompted that CPF is suspicious EEDs. The CPF male reproductive toxicity mainly for the changes of histopathology, sperm quality, hormone levels and testicular marker enzyme activities, suggesting the possible mechanism to lipid peroxide damage mechanism research is in the majority. In this paper the CPF male reproductive toxicity and possible mechanism are reviewed.


Cognitive Radio (CR) aims to achieve efficient utilization of scarcely available radio spectrum. Spectrum sensing in CR is a basic process for identifying the existence or absence of primary users. In spectrum sensing, CR users suffer from deep fading effects and it requires additional sensing time to identify the primary user. To overcome these challenges, we frame Spectrum Prediction-Channel Allocation (SP-CA) algorithm which consists of three phases. First, clustering mechanisms to select the spectrum coordinator. Second, Eigenvalue based detection method to expand the sensing accuracy of the secondary user. Third, Bayesian inference approach to reduce the performance degradation of the secondary user. The Eigenvalue based detection method is compared with Energy detection method in terms of varying false alarm rates and samples. The Eigenvalue detection method achieves better performance than Energy detection method. The Simulation results show that our approach gives better performance in terms of reducing sensing time and increasing sensing accuracy.


Abstract LiMnPO4/C samples were prepared by hydrothermal reaction, and also by solid state reaction for the comparison. The samples characterised by X-ray diffraction, scanning electron microscope, particle size distribution and Roman spectra. The influence of solution pH and calcination temperature on the particle size of LiMnPO4 sample was studied. Results showed that the sample synthesised at the optimal conditions of pH=6·0 and 680°C had the biggest lattice of LiMnPO4 crystal and the narrowest particle size distribution. Compared with solid state reaction, the hydrothermal reaction produced a better carbon coating to form LiMnPO4/C composite. Electrochemical property was tested by charge–discharge and cyclic voltammetry. As a result, the capacity of the optimal sample is 108 mAh g–1 and the capacity retention is 70% after 30 cycles. The Electrochemical performance of LiMnPO4/C prepared by hydrothermal reaction is better than that produced by solid state reaction.


Doping of an energy-transfer-type laser dye pair into an alumina film was tried in order to increase the efficiency of its photoproperties. A transparent alumina film was prepared from an aqeous sol solution by the sol—gel process. Changes in the fluorescence of the pyranine were monitored during the process from aqueous sol solution to the dried gel. The undesirable dye aggregation usually observed in aqueous solution was largely reduced in the film. The laser emission of rhodamine B by N2 laser pumping can be increased by the addition of rhodamine 6G, which enhances pumping efficiency. It indicates that this doped film operates as a compact dye laser film.


Mud crab of the genus Scylla are considered one of the most sought-after seafood today. This crab species has high quality and delicious aging growth rate and encourage expansion in the aquaculture sector especially in Southeast Asian Countries. However, salinity changes will cause changes in organisms osmotic pressure, and every aquatic biota has an optimal salinity range for survival. The study focuses on evaluating the effect of water salinity on the survival and osmotic levels of the purple mud crab, larvae of Scylla tranquebarica at the zoea stage. The LC50 assessment was performed in 10 different level of water salinity (0; 5; 10; 15; 20; 25; 30; 35, 40, and 50 ppt). Each treatment involved 20 ind./L of newly hatched crabs and being observed for 24 h in 10 different water salinity using 1 L volume glass container. The number of crab's mortality were taken for each salinity regime. Larval behavior monitored during experiment. Meanwhile, the measurement of osmotic level was carried out at the salinity of 25, 30, and 35 ppt. The result shows that mud crab larvae exhibit any tolerance on the low salinity ranged from 0-10 ppt and the salinity of > 40 ppt. On the other hand, mud crab larvae were still able to survive at the salinity ranged from 20-40 ppt for more than 24 hours. The trend of the osmotic level of mud crab to survive is by hypo osmotic to iso osmotic.

A series of guanidinate rare-earth metal complexes [(PhCH2)2NC(NC6H4iPr2-2,6)2]RE(CH2C6H4NMe2-o)2 (RE = Y (2a), La (2b), Dy (2c), Lu (2d)) were synthesized by the acid–base reaction of RE(CH2C6H4NMe2-o)3 with (PhCH2)2N[C(NHR)(NR)] (R = 2,6-iPr2-C6H3) (1) in THF. Treatment of complexes 2 with two equivalents of carbon dioxide, sulfur and phenyl isothiocyanate gave the corresponding insertion products {[(PhCH2)2NC(NC6H4iPr2-2,6)2]RE(μ-η2:η1-O2CCH2C6H4NMe2-o)(μ-η1:η1-O2CCH2C6H4NMe2-o)}2 (RE = Y (3a), La (3b), Dy (3c), Lu (3d)), {[(PhCH2)2NC(NC6H4iPr2-2,6)2]RE[μ-S(CH2C6H4NMe2-o)]2}2 (RE = Y (4a), La (4b), Dy (4c), Lu (4d)) and {[(PhCH2)2NC(NC6H4iPr2-2,6)2]RE{SC(CH2C6H4NMe2-o)NPh}2 (RE = Y (5a), La (5b), Dy (5c), Lu (5d)) in good yields, respectively. All new complexes were fully characterized by NMR spectroscopy and elemental analysis. The structures of 1, 2d, 3, 4a, 4c–d, 5a, and 5c–d were established by X-ray diffraction studies. Complexes 2 were found to have a high activity and excellent 3,4-selectivity for isoprene polymerization in the presence of [Ph3C][B(C6F5)4].


External wrench estimation has become a necessary part in many emerging applications of the Unmanned Aerial Vehicles (UAVs) such as aerial contact tasks, tactile mapping and human-UAV interaction, etc. Since measurement noises of sensors may be unknown or time-varying, this letter proposes a novel external wrench estimator based on variational Bayesian unscented Kalman Filter (VBUKF). The VB algorithm is combined into an UKF based estimator for estimating the external wrench and unknown measurement noise covariance simultaneously. Simulations and actual experiments are conducted to verify the proposed method. The results demonstrate that the VBUKF based estimator is robust to unknown and changing measurement noise. It has a good precision of external wrench estimation, which is consistent with the force sensor.


The purpose of writing this book was to produce information on and practical recommendations for informed decision-making on and capacity building for sustainable forest management (SFM) and good forest governance. This was done within the overall global framework for sustainable development with special emphasis on the EU-Africa relations and on Southern Sudan in particular. The case study on Southern Sudan focused on local, national and regional issues encompassing interviews and group discussions with local community members and government officials in Renk County in Upper Nile State. As a whole, this book attempted to link the global, regional, national and local levels in forest-sector development and especially to analyse how the international policy development in environmental and forestry issues is reflected in field-level progress towards SFM and good forest governance, for the specific case of Southern Sudan.


Since the coenzyme B12 was discovered as an active form of vitamin B12 (B12) by Barker et al. (1), its biochemical propaties including its coenzymic roles, and its metabolism have been studied in many respects. Today it is considered that vitamin B12 in the liver exists in a coenzyme form (2), 5, 6-dimethyl benzimidazolyl cobamide coenzyme (DBCC), which plays an important role in converting methyl malonyl CoA into succinyl CoA in mammalian cells (3, 4). On the other hand, studies on the enzymic biosynthesis of DBCC from B12 derivatives were made by Pawelkiwicz et al. (5) and Bernhauer et al. (6), who showed that the extract of Propionibacterium shermanii could catalyze the con version from aquocobalamin to coenzyme B12 in the presence of ATP and Mg. Barker and Brody et al. (7, 8) obtained the enzyme for biosynthesis using the same bacterium and searched for the substrate and cofactor necessary for biosyn thesis. Weissbach and Peterkofsky et al. (9-11) succeeded in the biosynthesis of DBCC using the cell-free extract of Clostridium tetanomorphum. On the other hand, Gorna (12) and Pawelkiwicz et al. (13) reported that the homogenate of liver and kidneys could convert cyanocobalamin (CN-B12) into DBCC in vitro. However, only short reports have been made on the conversion process in the body, of which Fenrych (14) used rabbits, and Martson (15) used the sheep. The present author (16) used animal tissues for the study of fractional deter mination of CN-B12, OH-B12, and DBCC and further studied the conversion process leading to DBCC in the liver and kidneys from 57Co-CN-B12 or 57Co-OH-B12 injected intravenously into rats or human subjects. He also examined the conversion pro cess in vitamin B12-deficient state and in the liver injured by carbon tetrachloride and observed how the conversion process was affected by intrinsic factor (IF) known to promote which is the organ uptake of B12.


Nowadays the peltier is used to cool the small device cooler when we apply DC voltage to its terminals. Instead of applying a DC voltage to the terminals, the peltier runs as a thermoelectric generator and we get DC voltages at its terminals, which we create a temperature difference between the two surfaces of the ceramic. In this way, electricity can be obtained directly from the heat flow by utilizing the waste heat of the resources we use (thermal water, car exhaust, boiler heat, solar energy etc.) that are stored around. In this study, copper material with high conduction of heat is preferred and two different thermoelectric modules are placed between the two plates which we traverse hot and cold water. These thermoelectric modules run as thermoelectric generators to compare current, voltage and power generation with different temperature.


Sexually transmitted diseases (STDs) are a major worldwide health problem that compromise reproductive fecundity as well as cut short the lives of millions of men, women and children.1,2 Despite extensive efforts, only limited success has been achieved in dealing with STDs, including herpes simplex virus type 2 (HSV-2), Chlamydia trachomatis, group B streptococcus and human immunodeficiency virus [(HIV), the causative agent of acquired immune-deficiency syndrome (AIDS)],3 which collectively devastate both adults and newborns. It is now well recognized that the heterosexual transmission of HIV, which is reponsible for 70–80% of the new cases identified in the last 2 years, is the major route of infection worldwide.4,5 With the identification of HIV in semen and cervical secretions,6–8 AIDS is now the major life-threatening STD.9,10 As strategies are developed to prevent and effectively treat this growing global health problem, understanding the immune system in the female reproductive tract and the way it is regulated by the endocrine system has particular importance.


Ground-based imaging of satellites during the daytime represents a formidable challenge due the strong turbulence induced noise in the imagery and the high background noise. Two important approaches for overcoming the problem of imaging through this strong turbulence include aperture partitioning and the collection of wavefront measurements for use in image restoration post-processing. The aperture partitioning enables a reduction in the turbulence induced noise in the recorded imagery, while the wavefront measurements can be used to constrain a frozen flow estimate of the wave front. Together the WFS measurements and FFM enable the recovery of high spatial frequencies in the wave front, which leads to higher fidelity estimates of the PSFs necessary for estimating the recovered image of the satellite. Improvements in image restoration due to the aperture partitioning will be demonstrated by comparing image restoration algorithms that used WFS data with imagery acquired using a filled aperture versus imagery acquired using an aperture partitioning scheme. This comparison will be made using imagery acquired in daylight using a 3m-class telescope.

This study was conducted in Gurage Zone at Wolkite University in 2016/17 cropping season. The field experiment was carried out in randomized complete block design (RCBD) using three replications and four treatments. The effect of different mulching material such as grass, banana, plastic and control mulch on growth parameters (plant height, germination rate, leaf number of branch per plant,) of hot pepper was conducted for three months. Data was collected and compared by using LSD at significant level of 0.05. The result showed that the highest and lowest plant height was obtained for grass mulch (T1) and control (T4) on the other hand no plant height was registered for plastic mulch. Generally, from the result of this study we recommended that farmers use of grass mulch increase the rate of hot pepper seedling and growth performance by maintain soil temperature, soil moisture and provide good air circulation with in soil spores than other mulching materials. The awareness of farmers should be increased by providing adequate training regarding with the type of appropriate mulching material, So, they can produce proper operation during the growth of paper to avoid the infestation of weed by mulching. According to analysis of variance there was significant different among treatments on the number of braches per plant and also results of the analysis of variance indicated that different mulching material were shown significantly (p>0.05) effect on plant height of pepper. However, there is no significant variation among the treatment for number of leaves. Since the recommended using vativar grass mulch until another investigation was done. This is a short term strategy; therefore, the study should be repeated over year. In order to address the significance of all the studied characters and to recommend the appropriate mulching material for further hot pepper production.


Popperism as pyrrhonin attitude: epistemic justification in Karl Popper Popper argues in the Logic of Scientific Discovery (published in 1934 in German) against both an externalist and an internalist epistemic justification for observational statements; Popper then opts in the LSD for a position that substitutes the justification of the basic statements of science with their criticism; and he stops a regress of criticisms with some conventional decisions. Later, in the Open Society (1945) he argues for a critical rationalism, one that requires some argumentatively unjustified and unjustifiable presuppositions, i.e., it requires some dogmas. The late Popper (circa 1983), seems inclined towards a pancritical rationalism, a position that leads, however, to a logical paradox, which can only be evaded if some presuppositions are to be accepted as not criticizable. Thus, the Popperian requires either some unjustifiable or some uncriticizable presuppositions. These dogmatic presuppositions should be believed passively and judgment about their truth value should be suspended. This is the Popperian's Pyrrhonian attitude. Key words: Critical rationalism, acritical rationalism, pancritical rationalism, Pyrrhonism, K. Popper, dogmatism, uncritizable, justification.


To meet the prerequisites and parameters in 5G, the existed Orthogonal Frequency Division Multiplexing (OFDM) modulation technique is not enough. So, an alternate technology called Universal Filtered Multi Carrier (UFMC) technique arisen. It is a 5G modulation technique. For UFMC, to withhold an orthogonality, Quadrature Amplitude Modulation (QAM) is being used and also suits for Multiple Input Multiple Output (MIMO) technology. This document describes the performance of UFMC modulation technique. In this paper we have chosen 256 bit and 1024-bit QAM Mapping technique. In simulation results, we observed the Peak to Average Power Ratio (PAPR) values of 256-bit QAM and 1024-bit QAM and it is implicit that the PAPR values in 1024-bit QAM have the low PAPR values. So, the best mapping technique in UFMC is 1024-bit QAM. In this article, we also evaluated UFMC's performance based on PAPR and spectrum utilization. And all the PAPR and (Bit Error Rate) BER values for both 256-bit and 1024-bit QAM are also included. The systems which are based on OFDM technique are vulnerable to high power amplifiers (HPA). Also due to multi carrier signal overlapping, the 4G OFDM technique suffers from high PAPR. The high PAPR causes a non- linear distortion in HPA. And we concluded that UFMC multi carrier technique also have high PAPR values, which implies to the high-power consumption.


Abstract : The response of a model helicopter rotor blade to random excitation while in simulated forward flight is studied analytically and experimentally by means of an electromechanical apparatus. Complex transfer functions are defined which relate steady-state responses in bending, flapping, and torsion modes to a sine input. Responses occur at the input and side-band frequencies. These transfer functions are then used along with excitation power spectra to predict the nonstationary time-averaged power spectrum of the response. Validity of the transfer function analysis is investigated by means of the electromechanical model which includes analog computer simulation of the interaction of blade deflections and aerodynamic load.

COVID-19 has impacted not only human lives, but also business organisations. The repercussions of the pandemic on global businesses include sustaining the value of a firm that could benefit stakeholders, such as the challenge for sponsored properties to attain sponsorship through a period of financial struggles and the capacity of a sponsor to provide it. It is imperative for business-to-business (B2B) communities to evaluate criteria and risks of sponsorship to instil public trust and consequently result in value creation for firms. At the same time, the role of the media is pivotal to create visibility of this partnership and achieve set sponsorship aims. With that said, the objective of this study is to explore the role of sponsorship decision making by Malaysian organisations during the pandemic and how the media have strengthened relationship marketing between businesses and their stakeholders; by examining the determinant factors of using media as an activation in sponsorship and the criteria of using media in sponsorship. The qualitative study conducted interviews with 13 corporate communication and marketing managers in Malaysia that are involved directly with sponsorship activation. The findings highlight the sponsorship ecosystem through the Malaysian media and B2B perspectives that would guide practitioners in making strategic decisions on B2B sponsorship matters, particularly on the relational approaches and media engagement should be seen as part of good business conduct. Future recommendation of this research is to seek the perceptions of consumers on the congruence of relationship marketing through sponsor-sponsored properties collaboration in Malaysian media. Keywords: Media, marketing communication, sponsorship activation, business-to-business, Covid-19.


This paper describes the development of a methodology for solid phase extraction (SPE) and pre-concentration of nitrosamines from aqueous samples using granular activated charcoal as stationary phase. micelar electrokinetic capillary Chromatography (MEKC) was used for the separation and identification of the nitrosamines in the extracts. Using a sample with 50 µg l-1 of each nitrosamines standards (dimethylnitrosamine, DMN; diethylnitrosamine, DEN; N-nitrosopyrrolidine, NPYR; N-nitrosopiperidine, NPIP; N-nitrosomorpholine, NMOR), the methodology showed a range of recuperation from 29 to 107% with a linear zone between 10 and 500 µg l-1. The developed methodology can be applicable to the determination of these analytes in different aqueous samples.

For over 300 years, the Library of the Serbian Orthodox Church is performing
 the task of the Keeper of the Memory and the Holder of the Spiritual and
 Cultural Continuity of its People. The Library emerged from the bosom of the
 Serbian Orthodox Church, and its destiny was determinate by historical
 events and versatile relation and interest of those being in charge of it and that way the Library remained out of the modern streams of the
 Librarianship. With an insufficiently researched Holdings, without any
 efficient instruments for Information - the Library is more a storage of
 precious books, and we are guessing its importance more than we know. To
 overcome this situation, a strategy should be conceived, which would regroup
 the effort of the Church, as the owner, and the goodwill of Makers of
 political decisions, to arrange the Library in a modern way and to put its
 holdings to a complete disposal to users. Therewith, our oldest Library
 would occupied the honorably place in Serbian Librarianship, where it
 belongs.

Within theological education, there are ongoing concerns that ministry education is dis-integrating and needs to recover by engaging a holistic focus. Training institutions are criticised for producing academically astute graduates, who lack the pastoral exposure or the required spirituality for Christian ministry. As ministry situations become more complex, an integrative approach to teaching and learning is required, since it connects learning to experience in an intentional way. Despite its complexity in implementing, integration as a method should be embraced more fully in the design and reformation of theological education. This article discusses proposals that can create spaces for integration, highlighting the place of disciplines of knowledge in curricular approaches, the theory-practice challenge, together with fostering active teaching and learning. These proposals are important considerations for purposeful theological education in this time of complex curricular changes in higher education.


This paper examines the effects of lexical stress on intensity and duration in Persian both in the presence of the intonational prominence contrast and in the abstraction from the compounding accent condition. A production study was conducted in which 10 speakers produced Persian lexical and reiterant disyllabic minimal stress pairs spoken with and without an accent in a fixed carrier sentence. Duration, overall intensity, and spectral levels in four contiguous frequency bands were measured. Results showed a significant difference in overall intensity and spectral tilt between accented and unaccented syllables. However, no significant differences were found for these measures between stressed and unstressed syllables in the absence of the accent contrast. In contrast, duration proved the most reliable correlate of stress, as Persian speakers produced stressed syllables consistently longer than their unstressed counterparts independent of the accompanying intonational prominence contrast.


In January 2003 Malaysia re-adopted the English language as a medium of instruction for science and mathematics in a move to keep abreast with scientific and technological development that is mostly recorded in the English language. To understand how this move changes the dynamics of teaching and learning mathematics and science in the Malaysian classroom, a study was conducted to obtain some feedback from Form One mathematics and science teachers. This paper reports the findings of the study and discusses some of the implications of the study for Malaysian school teachers and students.


The archaeological works done in the apse of the Dominican Convent in Castello d'Empuries (Alt Emporda, Girona) brought to light an exceptional collection made up of more than 6.000 pieces of pottery, thrown in order to build an embankment before 1512. Among the several items retrieved, the monochrome glazed pottery stood out both of its quantity and homogeneity, and thus it has become the central theme of the present study. This paper analyses the different documented forms (bowls, plates, jugs, pots, lids...), which have been organized into functional categories and structured according to the diff erent types.


Physical property data on density, viscosity, and electrical conductivity were developed and reduced to correlation form for synthetic electrolytes containing nominally 7 g/L Sn and 0.20 g/L Ga in 3,4,5,6 M NaOH. Concentrations of Al(OH)/sub 4/ were selected at six levels for each NaOH concentration and ranged from 0 to as high as 4 M Al(OH)/sub 4/ at 6 M NaOH. Measurements of each property were made at 25, 40, 60, and 80 C. The effect of the Sn and Ga impurities was to increase density by a relatively small percentage, increase viscosity by a significant percentage, and decrease electrical conductance by a significant percentage. Isothermal, batch precipitation experiments at 40, 60, and 80 C were utilized to develop data from which kinetic and solubility correlations were derived as functions of electrolyte and system parameters. Precipitation rate was negatively affected by tin in solution, with a 40% reduction in the rate constant being attributed to 0.06 M Sn. Both Sn and Ga co-precipitated with the Al(OH)/sub 3/ to an extent strongly dependent on temperature. Very high precipitation rates resulted in Na levels in product exceeding the target level of 0.24% Na on the hydrate basis. The incorporation of Na inmore » product was also a strong function of temperature. A total of 108 computer simulations were performed and documented to delineate the region of feasible operation with respect to meeting the aluminate production specification. A full-scale precipitator was operated in a continuous mode to assess production rate, population changes with time, and hardware aspects. A digester was used to perform the function of an Al-Air battery, that is to drive Al(OH)/sub 4//sup -/ into solution. Results are presented in detail. (WHK)« less


Objective This study aimed to test whether clinical characteristics, laboratory parameters, and measurements of serum fibroblast growth factor-23 (sFGF23) can discriminate between babies with neonatal sepsis and normal babies. Background Neonatal sepsis is associated with severe morbidity and mortality in the neonatal period, especially in developing and underdeveloped countries. Patients and methods This was a prospective (case–control) study conducted between April 2018 and November 2018, at the Neonatal ICU, Menoufia University Hospital, Menoufia, Egypt. The study comprised 79 full-term neonates. The neonates were categorized in two groups based on International Pediatric Sepsis Consensus Conference and Biochemical Markers, including complete blood count, C-reactive protein, and blood culture: first, control group included 30 neonates with routine screening; and second, sepsis group comprised 49 neonates with clinical sepsis (32 with sepsis and 17 with severe sepsis) (clinical and laboratory signs of infection with or without positive blood culture). Receiver operating characteristic curves were used for the determination of thresholds for the infection group vs healthy neonate group. Results A total of 79 neonates were enrolled in this study. sFGF23 increased in order of infection severity, being higher in patients with clinical sepsis than healthy subjects. Sensitivity, specificity, positive predictive value, and negative predictive value for sFGF23 levels were 89.8, 76.67, 86.3, and 82%, respectively. sFGF23 (cutoff point for sFGF23 >21.68 pg/ml) (P < 0.001), and there was a positive correlation between sFGF23 level and severity of sepsis (r = 0.37, P = 0.004). Conclusion sFGF23 may be a valid and early diagnostic marker of neonatal infection. Moreover, sFGF23 is associated with severity of sepsis.


Lucy Hawking has had the good fortune of being the daughter of the most famous living physicist; she has had the better fortune of having been a teenager before Stephen Hawking became famous, a time when he was known and respected only by other theoretical physicists. In this less hectic time, he was just a father, a man with a disability, to be sure, but not a disabled man, a sufferer from Lou Gehrig's disease who defied the odds. Who could view as disabled a man who zipped through the streets of Cambridge in a Formula 1 electric wheelchair driven at reckless speeds and, on one occasion at least, almost disastrous consequences? Hawking is now, perhaps, the most famous physicist since Einstein. While his work significantly expands the territory of the scientific sublime, his life embodies that sublime. This is not the ethical sublime that Rachel Carson, the subject of the next chapter, embodies; it is not a code of conduct. Rather, it is our firm sense that we are dealing with an extraordinary human being who has overcome daunting challenges to become an impressive virtual presence, a man who, alone among contemporary scientists, is a star, nay, a superstar. Confined to a wheelchair, he towers above us, an exemplar, a demonstration of just how deep a deep-seated commitment to science can be. But is he any good at physics? Is it all hype? His heroes—Galileo, Newton, and Einstein—are models he cannot hope to emulate. Those on whom he consistently relies—Werner Heisenberg, Paul Dirac, and Richard Feynman—are clearly his superiors. True, he is an elite physicist honored by his peers, but he is more a Dom than a Joe DiMaggio, excellent, though not the very best. As he says himself, "To my colleagues am just another physicist." But his professional reputation hardly matters, because, as he asserts with characteristic good humor: . . . To the wider public I became possibly the best-known scientist in the world. This is partly because scientists, apart from Einstein, are not widely known rock stars, and partly because I fit the stereotype of a disabled genius. I can't disguise myself with a wig and dark glasses—the wheelchair gives me away. . . .


Step inside any organization, even a very successful one, and you'll probably find a lot of waste if you know where to look. From providing a feature that consumers don't care about to exhausting efforts on tasks that only require adequate attention, there are countless areas where resources go down the drain. In Low-Hanging Fruit, Jeremy Eden and Terri Long provide seventy-seven of their most effective techniques for improvement, each drawn from their success working with major companies.


Acute febrile illness caused by multiple infectious etiologies is not uncommon, especially in endemic countries like India. Recently, there has been increased mortality with chikungunya infection in children. There are several studies of coinfection of chikungunya with dengue, but coinfection with rickettsial infection is rare. We describe a 14-year-old boy presenting with chikungunya with probable rickettsial coinfection with a fatal outcome.
