The theory of planned behavior presents clear operational definitions of attitudes, subjective norm, perceived behavioral control, and each of their corresponding belief-based measures. Theoretically, the direct and indirect measures of a given construct must be closely correlated. Empirical results, however, indicate that this is not always the case. In the present study, 2 of the factors that could be responsible for this situation-namely, the scaling of the variables defining each belief-based construct and the adequacy of using an expectancy-value model within the belief-based measures-were verified among a data set of 16 studies concerned with the application of the theory of planned behavior to the field of health. The results indicate that the scaling method used affected the correlation coefficients between indirect and direct measures. However, the face validity of these scaling methods must be demonstrated. The results also support the idea that, in most cases, using the expectancy-value model is no better than using only one arm of the belief-based measure.


Acrylon-ethylized starch graft cationic polyacrylate amide copolymer as the paper dry strengthening agents is prepared by soap-free emulsion process with cationic starch,acrylate amide,vinylcyanide as the main materials.The effects of the parameters are studied.The optimum reaction conditions are described as follows:85℃,5 hours of soap-free emulsion polymerization,w(AN)=1.5%,w(GMA)=0.8%-0.9%,and 1∶1 of m(cationic starch)∶m(acrylate amide).Thus the intensity performances of the ring crush strength and bursting strength can be increased by 29.5% and 45%,respectively,when the dosage of emulsion is 0.4%.And the copolymer is characterized by SEM,DSC and XRD.


In Part 1 of this two-part paper, we review the development of open architecture controllers for machine tools. General design principles are described, followed by specific hardware and software recommendations. These specific recommendations are then used for the construction of an open architecture device, MOSAIC-PM, (Machine tool Open System Advanced Intelligent Controller for Precision Machining). The machine has now been used in a wide variety of experiments to demonstrate open architecture control. These experiments include sensor based machining, rapid prototyping and manufacturing over the Internet. In Part 1, a specific application on feature based precision machining with on-machine acceptance is described. A more specific implementation of a quintic spline interpolation method is described in Part 2.


C is based on the primary experience of Easter. So it is worthwhile to think and meditate about the fundamental truth of Christian faith, namely, Jesus' Resurrection. New Testament faith is a priori eschatological and depends on the Easter kerygma, the Resurrection of Jesus. This has been rightly pointed out by Jürgen Moltmann: "Christianity stands or falls with the reality of the raising of Jesus from the dead by God."1 Faith in the Resurrection is also faith in the God who raised Jesus Christ from the dead. Therefore, "Faith in the God 'who raised Christ from the dead' and the confession that 'Jesus Christ is the Lord are mutually interpretative."2 Nevertheless the death and resurrection of Christ constitute one single action, which resumes in itself the entire life of Christ. And the stories of the resurrection, in fact, acquire credibility and reliability after the recognition of the truth of Christ's crucifixion, not before. Therefore, the heart of Christian faith is in the incarnate and crucified Son of God raised from the dead by the power of the Spirit (Rom. 8:11; 1 Cor. 6:14).


Based on the idea of the encryption algorithm, a new method for data storage in cloud computing is designed. First of all, gives the cloud data security framework in 9 steps; secondly, the data encryption and data decryption algorithm is designed by combining the multiplication, addition, update algorithm and the specific operation; thirdly, combining the index and scanning technology and according to the reverse order strategy design a data retrieval algorithm. Experimental results show that the proposed method in data encryption, data decryption, data retrieval and other aspects of the implementation of the efficiency is significantly higher than the BGV algorithm, and more suitable for the safe storage of cloud data.


The aim of this paper was to analyze the high temperature embrittlement of TiNb IF steel using plastometric torsion tests. High temperature embrittlement in the temperature range 600 - 1200°C is a problem mainly connected with additions of microalloying elements to steel and also with inhomogeneous and coarse-grained microstructure formed during continuous casting. Reduction of high temperature ductility can lead to cracks in the slab. These surface cracks can easily become oxidised, and then they do not fuse during forming operations. A significant decrease in hot ductility of the analyzed steel occurred in the stable austenite just above the temperature of 1100°C, where the number of rotations to failure (N f ) in the sample was lowest, at 28.4. The cavities ratio was 1.9%, which occurred mainly below the fracture line. At the bottom of the dimple transcrystalline ductile failure (DTDF), complex particles based on Al, Ti, Mn, S, N were observed. In this temperature range the embrittlement is mainly attributed to fine precipitation of sulfides, oxides, particulates based on microalloys as well as segregation of impurities on the austenite grain boundaries.


Electricity generated from renewable energy sources is becoming widespread due to the adverse environmental effects and increasing costs associated with the use of conventional energy sources like fossil fuels, hydel and nuclear. Electricity generated from readily available renewable energy sources like solar and wind are great alternatives and have the potential of satisfying the energy requirements to a great extent. However, solar and wind energy used independently are not entirely reliable due to their unstable nature and intermittent availability. The use of solar and wind energy together as a hybrid energy system has been found to be more efficient and economically viable. The objective of this paper is to carry out a feasibility study of standalone solar-wind hybrid energy system in Guwahati. Solar irradiation and wind speed of various locations of the city has been collected for the work. A standalone hybrid energy system comprising of solar panels, wind turbines and battery bank supplying an assumed load is used for this study. Particle Swarm Optimisation (PSO) technique is employed to find the optimal number of solar panels, wind turbines and batteries keeping load fulfillment and economical constraints in mind. The study concludes by identifying the hot spots in the city where solar wind hybrid energy systems are feasible.Electricity generated from renewable energy sources is becoming widespread due to the adverse environmental effects and increasing costs associated with the use of conventional energy sources like fossil fuels, hydel and nuclear.

This study examines how company experts and their interactions with management and the auditor affect the fair value measurement (FVM) process. We conduct detailed interviews with 19 Norwegian company experts who possess expertise in financial instruments, investment property, oil & gas reserves, and shipping and 8 audit partners with extensive valuation experience to investigate theoretical predictions derived from agency theory and the monitoring role of company experts. Overall, the results support our predictions. Company experts: (1) have incentives to build and maintain their reputation, (2) face management pressure, and management uses several tactics (i.e., reappointment and multiple company experts) to influence their FVM, (3) are aware that providing multiple services (e.g., brokerage and trading) can affect their FVM but believe that there are adequate safeguards in place, and (4) differ by type of expert in allowing auditor access to their models and data. We also find variation by type of company experts' interaction with the audit team and their perceptions of the audit teams' narrow focus on individual model assumptions. These findings inform researchers, regulators, and practitioners about the role company experts play in the FVM process.


It is impossible to directly analyze the microstructure of spin-valve multilayers based on Ni, Fe, Cu and Mn by a conventional X-ray diffraction technique because the lattice parameter and atomic scattering factors of them are very close. To solve this problem, we use an X-ray anomalous diffraction technique to characterize the microstructures of the [Ni80Fe20/Fe50Mn50]15 and [Ni80Fe20/Cu]15 superlattice systems. The results show that more diffraction peaks and higher intensity in the reflectivity profile are observed when the incident energy is close to the absorption edge of the lighter element (Mn) in [Ni80Fe20/Fe50Mn50]15 multilayer systems and to the absorption edge of the heavier element (Cu) in the [Ni80Fe20/Cu]15 multilayer systems. The interface and periodic structure of [Ni80Fe20/Fe50Mn50]15 are more perfect than that of the [Ni80Fe20/Cu]15 superlattices. The above results are discussed in this paper.


Swine vesicular disease (SVD) caused by enterovirus broke out for the first time in Japan in November, 1973. It occurred originally in a region producing breeding swine in Kanagawa Prefecture and prevailed up to the next month. Then an antibody survey was conducted to clarify the degree of infiltration of this virus among swine. Incidentally, antibody against SVD virus was detected in it from the sera of some swine which were considered to be free from the outbreak of SVD. These sera included those collected before the present outbreak and those harvested from swine produced and raised on farms in a region geographically apart from the site of the outbreak.SVD virus is antigenically very well identical with Coxsackie virus B5 (CB-5), which is human enterovirus. Serum samples were collected from swine in the field and examined for the presence of antibody against CB-5 virus. Then studies were made on the relationship between this antibody and that against SVD virus with the following results.1. Serum samples were collected from swine all over Japan at three points of time; that is, prior to the outbreak of SVD and 1 and 5 months after the termination of this outbreak. Serum positive for SVD antibody was detected at every point of time. The coefficient of correlation between the two types of antibody, however, was considerably low, or 0.34, 0.31, and 0.34 before and 1 and 5 months after the outbreak, respectively.2. When serum samples were collected from swine apparently infected on farms involved in the outbreak of SVD and examined for the two types of antibody, there was a very high correlation (r=0.74-0.85) between the antibody titers of these two types.3. The coefficient of correlation was low, or 0.44, in serum samples collected from swine manifesting only indistinct signs of infection and from those which had withstood the infection without showing any symptom on farms involved in the outbreak of SVD. It was also low, or 0.53, in serum samples (antibody titer, <44.0) harvested from swine which seemed to be in the ascending stage of antibody.From these results, it was suggested that there might be an inapparent infection of swine in Japan with such type of virus as mentioned above which would not cause the production of vesicles, but that of low-titer antibody. As such virus, CB-5 virus, which was antigenically identical with SVD virus, or any other unknown virus was presumed to exist.


Objective To investigate the expression levels and the roles of IL-17 and IL-23 in children with Mycoplasma pneumoniae(MP) pneumonia. Methods One hundred and three children with pneumonia admitted to pediatric department from February to May in 2012 were divided into MP pneumonia group and non-MP pneumonia group according to the results of MP antibody tests. Meanwhile,42 healthy children were chosen as normal controls. Serum levels of IL-17,IL-23 and MP antibodies were measured in all children. Immunoglobulin,C reactive protein,total white blood cell count and granulocyte count were detected in children with pneumonia. Results The serum levels of IL-17 and IL-23 were significantly different among three groups(P0.05). The children in MP pneumonia group had higher levels of IL-17 and IL-23 than those in non-MP pneumonia group(P0.05). Compared with the control group,levels of IL-17 and IL-23 were higher in two pneumonia groups(P0.05). There was no significant difference in levels of IL-17 and IL-23 between pneumonia patients with normal and with abnormal levels of immunoglobulin(P0.05),while IL-17 and IL-23 levels were both positively correlated with granulocyte count(P0.05).Conclusion IL-17 and IL-23 may be involved in the immune response of MP pneumonia and may contribute to the clearance of pathogens.


The role of serum amyloid A and TGF-beta 1 in chronic obstructive pulmonary disease (COPD) is controversial. Aim: to determine the serum level of TGF beta 1 and inflammatory biomarker such as serum amyloid a (SAA) and its relationship in stable COPD patients Materials and Methods: We studied 37 pts in stable phase of COPD (age – 63,4 ± 1,1 yrs). The control group consists of 10 healthy subjects. Measurements included clinical status, spirometry and serum levels of SAA, and TGF beta 1. Results: Serum levels of TGF beta 1 were elevated in COPD patients as compared with healthy controls (p = 0,000). Levels of SAA was also elevated (p = 0,001). TGF beta 1 was negatively correlated with SAA (p= 0,014, r= - 0,428); number of exacerbations in the past year (p= 0,487, r = - 0,004). Conclusion: High inflammatory biomarkers levels and frequent exacerbations in the past year associated with low TGF beta 1 level in COPD patients. Our study showed that high level of TGF beta 1 associated with long period (more than 6 month) of COPD stability. TGF beta 1 can be as anti-inflammatory biomarker in COPD.


The present study aimed at developing Responsible Environmental Behaviour in Indian adolescents . A sample of 260 students of class IX studying in Private Schools of Patiala affiliated to CBSE, constituted the population for the study.

This paper is aimed at predicting the life of rubber insulating gloves under normal operating stresses from relatively rapid test performed at higher stresses. Specimens of rubber insulating gloves are subject to multiple stress conditions, i.e. combined electrical and thermal stresses. Two modes of electrical stress, step voltage stress and constant voltage stress are used in specimen aging. There are two types of test for electrical stress in this experiment: the one is Breakdown Voltage (BDV) test under step voltage stress and thermal stress and the other is lifetime test under constant voltage stress and temperature stress. The ac breakdown voltage defined as the break-down point of insulation that leakage current excesses a limit value, l0mA in this experiment, is determined. Because the very high variability of aging data requires the application of statistical model, Weibull distribution is used to represent the failure times as the straight line on Weibull probability paper. Weibull parameters are deter-mined by three statistical methods i.e. maximum likelihood method, graphical method and least squares method, which employ SAS package, Weibull probability paper and FORTRAN, respectively. Two chosen models for predicting the life under simultaneous electrical and thermal stresses are inverse power model and exponential model. And the constants of life equation for multistress aging are calculated using numerical method, such as Gauss Jordan method etc.. The completion of life equation enables to estimate the life at normal stress based on the data collected from accelerated aging test. Also the comparison of the calculated lifetimes between the inverse power model and the exponential model is carried out. And the lifetimes calculated by three statistical methods with lower voltage than test voltage are compared. The results obtained from the suggested experimental method are presented and discussed.


Features of chemical fiber industry determine the features of financial management. At present, the chemical fiber industry is facing rigorous business environment, for example, centralized releases of capacity, demand growth slowing down, production cost staying at a high level, which makes the chemical fiber enterprises need to change and update the traditional concept of financial management urgently into value-creating financial management mode. As a leading enterprise in chemical fiber industry, through introducing high-quality talents of financial management, with the help of VBM concept, Hengyi Group takes the lead in developing innovative financial management mode in the industry, establishing value management institutions to undertake the function of creating value directly, supporting the function of creating value indirectly and protecting value from losing so as to promote the enterprise to create the whole value. Such successful practice of value-creating type financial management mode can be taken as reference for chemical fiber enterprises which are staying in the period of industry adjustment to get rid of difficulty, turn a profit and realize transformation and upgrading.


The paper examines the design and the construction details of the test bed built for testing a solid-amine-based Regenerable CO2 Removal System (RCRS) built at the NASA/Johnson Space Center for the extended Orbiter missions. The results of tests are presented, including those for the adsorption breakthrough and the adsorption and desorption of CO2 and H2O vapor. A model for predicting the performance of regenerative CO2 and H2O vapor adsorption of the solid amine system under various operating conditions was developed in parallel with the testing of the test stand, using the coefficient of mass transfer calculated from test results. The results of simulations are shown to predict the adsorption performance of the Extended Duration Orbiter test bed fairly well. For the application to the RCRS at various operating conditions the model has to be modified.

The term cryptography which means "secret writing", has become the foundation primitive in providing security for many communication applications. In many applications, particularly in group communication, there is a need to hide secret data like passwords, encryption key, recipes etc. Here efficient key management protocols are required to provide security for group's secret data. Because it is very challenging to provide security for group's secret data, especially in two scenarios: when the number of group members more and when the group members are present in different locations with diverse mechanisms of protection. The cloud computing where application services are provided through the internet. Cloud computing is a flexible, cost-effective, and proven delivery platform for providing business or consumer IT services over the internet. The cloud computing not only provides additional computing resources, but also network infrastructure which supports group communication scenarios. To interact with various services in the cloud and to store the data generated/processed by those services, several security mechanisms are required. In this context, this paper investigates the basic problem of cloud computing key management and enabling support for interoperability between cloud cryptographic clients and cloud key management servers. Cloud key management includes its creation and its subsequent adoption to reduce the complexity of encryption key management, infrastructure costs and risks and also to enhance the performance of both private and public storage cloud is discussed. This paper deals with the elaborate survey of existing key management techniques in cloud computing security and there by exploring the possible solution for cloud computing


Abstract The space group of a cubic phase of Zn63Mg23Er14 has been determined to be F4̅3m by convergent-beam electron diffraction (CBED). This space group is in agreement with that assumed by X-ray structure analysis (Sterzel et al., Philos. Mag. Lett. 80 (2000) 239-247). A rhombohedral phase, which is considered as a superlattice ordered phase of the cubic phase, was found. The space group of the rhombohedral phase has been determined to be R3m by the CBED method.


This paper deals with a simple and green method to synthesize N-methyl aniline under mild condition. A series of mixed metal salt (Zn and Cu salts) modified kaolin catalysts used in the above-mentioned reaction were synthesized and characterized by a Fourier transform infrared spectrometer (FTIR), X-ray diffraction (XRD), and scanning electron microscopy (SEM), which exhibited that kaolin was successfully modified by the mixed metal salts. The effect of the reaction time, catalyst, and initial pH on the reaction was recorded by an ultraviolet−visible (UV−vis) spectrum, and the electron spectrum prediction result of the catalyst effect was further confirmed by gas chromatography/mass spectrometry (GC/MS). In addition, N-methyl aniline extracted from the most optimized condition gave a good result in improving the gasoline octane number; however, more research needs to be carried out.


Downtowns used to be coveted as places in which to live. Except for such notable examples as Manhattan Island, Chicago's Northside, and San Francisco, nearly all downtowns since the end of World War II have lost population to the suburbs. Their allure may be returning, however. Many downtowns have rebounded and now contain more people and households than a decade ago. This Forum discussion comments on the extent to which downtowns are attracting people and households. It begins with a general assessment of the increasing share of new residential development being attracted to central cities, placing downtowns within that context. Using proprietary data acquired by the writers, it then reports general trends of downtown area residential development from 1980 through 1999 among 19 cases selected for this study. The discussion divides the sample of downtowns into those that experienced sustained flight or sustained attraction throughout the study period, or rebounded during the 1990s after a decline during the 1980s. This is followed by a snapshot of who lives in downtown areas. The discussion concludes with an assessment of the extent to which downtowns may accommodate the metropolitan demand for residential development, concluding that at their best downtowns are not likely to attract more than perhaps a percent or so of future metropolitan regional population growth. The Wichita Business Journal once observed that, "If you lived downtown, you could be home now" Miara 1998 . The article proceeded to examine the status of the downtown housing market in six cities throughout the United States. At the time, the renewed interest in downtown housing was quickly becoming a hot topic for debate for a wide variety of audiences. Downtown housing was being discussed in newspapers and trade journals, by public policy analysts and young professionals contemplating their futures. Certainly this last group is a major contributor to the building momentum of the downtown housing market. The link between images in popular culture of the intown lifestyle and consumer demand for urban living has become increasingly clear in the past decade. Groth 1994 and Karp et al. 1991 give us the sense of what it may be like to live downtown. Now we find downtown living is popularized on television and in the movies. With the introduction of "Generation X" into the housing market, the allure of downtown living has been rekindled, at least for now Birch 2002, 2005 . Consider also Houston's 1998 obser-

Objective To explore the mental health and caping style of clinical nurses and the relationship between them. Methods SCL-90 and the Coping Strategy Scale by Xie Ya'ning were used to investigate the mental health and the coping strategies among 65 clinical nurses. Results (1) The grades for all the factors in SCL-90 except the factor of interpersonal communication were higher than those in the Chinese norm. By comparison, there were significant differences in 4 factors and positive items (P0.05). The total grade and positive items in number were higher than those of the Chinese norm.(2) The common mental disorder included anxiety and compulsion. (3) The average grade in SCL-90 and passive coping measures were highly related in a positive way (P0.05). Conclusion The level of mental health of clinical nurses is lower than that of normal groups and closely related to the coping strategies.


Trophic dynamics within aquatic systems are a predominant regulator of fish production and an important consideration for implementing ecosystem approaches to fisheries management. We analyzed 10 years of fish diet data from Chesapeake Bay, USA, to (1) evaluate the effects of environmental variables on trophic interactions of 12 common predatory fishes, (2) infer dynamics of four key prey groups (mysids, bay anchovy, bivalves, and polychaetes), and (3) evaluate whether interannual dietary trends were coherent among predators and regulated by prey availability. Based on delta generalized additive mixed models (delta-GAMMs), predator length was the most important covariate in modeling prey consumption. When latitude, temperature, and depth effects were statistically significant, the effects of each variable were largely similar across predators for a given prey. Annual patterns of mysid and bivalve consumption each showed a single, dramatic peak shared by multiple predators with varied feeding preferences a...

Conditions are given under which a fibrewise flow on a fibre bundle must have a nonempty catastrophe space. 1. The problem. When we formulate the catastrophe theory of R. Thorn globally we have a fibre bundle E over a connected finite CW-complex B. The fibre M of E is a closed C manifold, and the structure group of F is a subgroup of the group Diff M of C diffeomorphisms M —► M with the C topology (r > 1). We say that F is a C bundle for short. Then B is the space of observables and M is the manifold of internal variables. Let Vect M be the space of C~l vector fields on M with the C_1 topology. We define an action '-'of Diff M on Vect M by means of the identity /• V = {df)Vf~x where / E Diff M, V E Vect M. In catastrophe theory the bundle with fibre Vect M associated with F has a cross-section. We think of this cross-section as a family Vb (b E B) of fibrewise C'~ ' vector fields on E. We next define an attractor of a vector field. The definition in [5, §4.1] seems to be imprecise and we use the following definition instead. Definition. An attractor of V E Vect M is a closed invariant subspace A of M such that (i) there is an invariant neighbourhood U of A for which n r>o «¿V» U = A, (ii) some trajectory of V is dense on A (here <j>y is the flow on M corresponding to V). Perhaps an attractor ought to satisfy additional conditions but these would not affect our main results. We suppose that we are given a convention, namely an assignment to each b E B of an attractor Ab of Vb. We think of a convention as a physical law, and of Ab as the physical state of B. Then b E B is said to be regular when it has a neighbourhood W for which there is a fibre-preserving homeomorphism n: F | W —» W X Eb onto the trivial bundle satisfying (i) h\Eb is the identity, (ii) h\Ac = Ab and h<j>y = <t>yh for all c E W. The points that are not regular make up the catastrophe subspace K of B. The purpose of this paper is to study the following problem. Suppose that we are given F and a closed connected subspace F of M. Then we wish to decide whether K can be empty with A0 = F, that is to say whether there is a family Vb (b E B) of fibrewise Cr~x vector fields on F and a convention such that K is empty and A0= F. Here 0 is the basepoint of B. Received by the editors January 16, 1979 and, in revised form, June 5, 1979. 1980 Mathematics Subject Classification.

Free coherent states for a system with two degrees of freedom is defined. Existence of the homeomorphism of the ring of integer 2-adic numbers to the set of coherent states corresponding to an eigenvalue of the operator of annihilation is proved. It is shown that the metric of free Fock space induces the 2-adic topology on the set of coherent states. Free (or Boltzmannian) Fock space has been considered in some recent works on quantum chromodynamics [1], [2], [3] and noncommutative probability [4], [5]. The subject of this work is free coherent states. We will introduce free coherent states and investigate the metric space of coherent states corresponding to a fixed eigenvalue of the operator of annihilation. It will be shown that archimedean metric of Hilbert space induce non-archimedean metric on the set of free coherent states. The main result of present paper is the construction of the homeomorphism from the ring of integer 2-adic numbers to the space of free coherent states with topology defined by the Hilbert metric. We will consider the system with two degrees of freedom. The system with one degree of freedom was investigated in [6]. The free commutation relations are particular case of q -deformed relations with q = 0. A correspondence of q -deformed commutation relations and non-archimedean (ul-trametric) geometry was discussed in [7]. Non-archimedean mathematical physics was studied in [8]. coherent states lies in the free Fock space. Free (or Boltzmannian) Fock space F over a Hilbert space H completion of the tensor algebra


Corticosteroids (CS) are potent immunosuppressive agents that are known to affect T cell‐mediated inflammation by the inhibition of proliferation and cytokine production, as well as the immunostimulatory function of monocytes and macrophages. Not much is known of the effect of corticosteroids on dendritic cells (DC), the professional T cell stimulatory antigen‐presenting cells. We report that the endogenous CS hydrocortisone and the synthetic CS clobetasol‐17‐propionate strongly inhibited the production of the inflammatory mediators interleukin (IL)‐12 p70, tumor necrosis factor α (TNF‐α), and IL‐6 by lipopolysaccharide (LPS)‐stimulated monocyte‐derived immature DC (iDC) in vitro. In contrast, the stimulatory capacity, antigen uptake, and the expression of costimulatory molecules were not affected. In accordance with the decreased production of IL‐12 p70, CS‐treated iDC induced less production of the inflammatory Th1 cytokine interferon‐γ and enhanced levels of the Th2 cytokines IL‐10 and IL‐5 in staphylococcal enterotoxin B‐stimulated CD4+ Th cells. Furthermore, CS inhibited the maturation of iDC as assessed by the lack of expression of CD83 as well as by the prevention of the loss of antigen uptake capacities. These type 3 DC (DC3) matured in the presence of CS produce less IL‐12 p70 and have a decreased T cell stimulatory capacity. Moreover, uncommitted T cells that encounter the CS‐induced DC3 develop into Th2‐biased cells, which may additionally decrease the Th1‐mediated tissue damage but, on the other hand, Th2 cytokines may promote undesirable elevation of IgE and eosinophilia. These findings indicate that suppression of T cell‐mediated inflammation by CS not only relies on direct effects on T cells, but also on various effects on DC, their professional antigen‐ presenting cells.

Imaging of high-speed incandescent dust particle trajectories in a tokamak plasma has been accomplished on NSTX using up to three high-speed cameras each viewing the same plasma volume from different locations and operating at speeds up to 68000frames∕s with exposure times varying from 2to300μs. The dynamics of the dust trajectories can be quite complex exhibiting a large variation in both speed (10–200m∕s) and direction. Simulations of these trajectories will be utilized to ascertain the role dust may play in future machines such as ITER where significant dust production from wall erosion is expected. NSTX has numerous view ports including both tangential as well as radial views in both the midplane and lower divertors. Several vertical ports are also available so that a few specific regions in NSTX may be viewed simultaneously from several different camera positions. The cameras can be operated in the full visible spectrum but near-infrared filters can be utilized to enhance the observation of incandesc...


In the years 1963 to 1981, 276 patients were admitted to the Eye and Ear Hospital and St. Vincent's Hospital, Dublin, with eyes perforated in road traffic accidents. An almost equal number of patients was admitted with non-perforating injuries of the eyes and trauma to the ocular adnexa, making a total of over 500 cases. The accompanying histogram shows the distribution of perforating eye injuries over these 19 years. It can be seen that the incidence of the injuries increased dramatically in the early 1970s, was checked owing to the energy crisis of the mid-1970s, but continues at an unacceptably high rate into the 1980s.

The high demand of aircraft maintenance technicians in Indonesia, present challenges to higher education practitioners. In 2015, Indonesia requires at least 6500 aircraft maintenance technicians as the estimated   number of active technicians in 2015 is about 3700 technicians, and the number is decreasing due to the retirement. Current institutions which offer the education and training program have the capability to train up to 840 technicians. The Department of Aeronautical Engineering, University of Suryadarma, has redesigned the curriculum and syllabi of the program to match the needs of the aircraft maintenance industry. The approach is to introduce the standard competency, as required by the industry, in accordance with the framework of curriculum standard design for the diploma program. The industry standard competency for aircraft maintenance technician is based on the CASR (Civil Aviation Safety Regulations) Part 147 and, CASR Part 65 recommended by DGCA (Directorate General of Civil Aviation), the Ministry of Transportation of The Republic of Indonesia, and ICAO (International Civil Aviation Organization) Document 7192. The Framework of curriculum design for diploma program is following the Republic of Indonesian Law No. 12 of 2012 for Higher Education, Presidential Decree of The Republic of Indonesia No. 8 of 2012 for IQF (Indonesian Qualification Framework).  This paper presents the recommended expected learning outcome and operational curriculum that satisfies the standard competency of aircraft maintenance technician, within the framework of standard curriculum design for the diploma program.


The design, fabrication and performance evaluation of a novel micro-igniter for micro-solid propellant thrusters are presented. The micro-igniter consisted of the membrane and the heat coil, and it was fabricated using a glass wafer for its structural stability. To improve uniformity and ignition characteristics, the glass membrane was fabricated by a polishing process for making its thickness uniform. Also, the heat coil was placed at the bottom of the membrane to contact with a propellant directly. In this study, the micro-igniter was designed including the chamber and upper layers for carrying out firing tests. After the micro-igniter was fabricated, uniformity and ignition characteristics were evaluated successfully, and the minimum distance between unit-igniters in an array was decided by firing tests.


Single image calibration is a fundamental task in photogrammetry and computer vision. It is known that camera constant and principal point can be recovered using exclusively the vanishing points of three orthogonal directions. Yet, three reliable and well-distributed vanishing points are not always available. On the other hand, two vanishing points basically allow only estimation of the camera constant (assuming a known principal point location). Here, a camera calibration approach is presented, which exploits the existence of only two vanishing points on several independent images. Using the relation between two vanishing points of orthogonal directions and the camera parameters, the algorithm relies on direct geometric reasoning regarding the loci of the projection centres in the image system (actually a geometric interpretation of the constraint imposed by two orthogonal vanishing points on the 'image of the absolute conic'). Introducing point measurements on two sets of converging image lines as observations, the interior orientation parameters (including radial lens distortion) are estimated from a minimum of three images. Recovery of image aspect ratio is possible, too, at the expense of an additional image. Apart from line directions in space, full camera calibration is here independent from any exterior metric information (known points, lengths, length ratios etc.). Besides, since the sole requirement is two vanishing points of orthogonal directions on several images, the imaged scenes may simply be planar. Furthermore, calibration with images of 2D objects and/or 'weak perspectives' of 3D objects is expected to be more precise than single image approaches using 3D objects. Finally, no feature correspondences among views are required here; hence, images of totally different objects can be used. In this sense, one may still refer to a 'single-image' approach. The implemented algorithm has been successfully evaluated with simulated and real data, and its results have been compared to photogrammetric bundle adjustment and plane-based calibration.


Nowadays,targeted therapies for lung cancer have entered into the clinical phase.Anti-epidermal growth factor receptor(EGFR)drugs,such as gefitinib and elotinib,and anti-vascular endothelial cell growth factor receptor(VEGFR)agent bevacizumab have been successfully applied in the clinical treatment of lung cancer.However,the mechanism for tumorigenesis of lung cancer is complicated.Anti-EGFR and anti-VEGFR therapy have some limitations and weakness.In recent years more and more attention has been focused on some new molecular targets in lung cancer,such as echinoderm microtubule-associated protein-like-4/anaplastic lymphoma kinase(EML4-ALK)fusion gene,mammalian target of rapamycin(mTOR),insulin-like growth factor type I receptor(IGF-1R),and mesenchymal epithelial transition factor(c-MET),and so on.In the present paper we review the roles of these new biomarkers in lung cancer therapy and the progress in clinical research.


"Immediately before the outbreak of World War II, Nazi Germany and Soviet Russia signed the Non-Aggression Pact of August 23, 1939, generally referred to as the Molotov-Ribbentrop Pact. This treaty contained secret provisions for dividing Eastern Europe into spheres of influence. " This pact is considered by many as one of the reasons for the onset of World War II. For Estonia, the Pact had terrible results. On June 17, 1940, Estonia was occupied by the Soviet Union. The Soviet secret police began to imprison and execute the population.

ment is, as the authors point out in their preface, &dquo;... specifically addressed to emergency acute care medicine and critical care practitioners.&dquo; The book is organized in a logical manner, beginning with the physiological and psychological aspects of pain. The first chapter is a superficial discussion of the physiological mechanisms of pain. I do not see this as a drawback, because its purpose does not appear to be an indepth discussion but rather a broad overview. There are, however, some weaknesses in this chapter. The section


Fraunhofer hologram camera systems have been applied to a number of applications for particle‐size analysis. Reconstructed holograms provide high‐quality images with three orders of magnitude greater depth of field than that provided by a microscope. Instantaneous recording of dynamic dispersions with freedom from isokinetric sampling losses is one of the chief attractions of the method. A permanent record of the particle distribution that can easily be recalled is produced. The typical laser pulse length of 20 nanoseconds allows particles to be moving at high velocities; the maximum particle velocity criterion is that the particle shall move less than 1/10 diameter during the exposure time.


Three phase power in solar PhotoVoltaic (PV) application is often unbalanced due to non-uniform radiation and temperature level on each cluster solar PV array. This is also true for PV fed cascaded H-bridge (CHB) multilevel converter. Thus the grid current supplied by the converter is unbalanced which is not desirable in balanced grid system. For supplying balanced three phase current, a common mode voltage is added with the pole voltages of CHB converter. It circulates active and reactive power in the phase clusters and allows balanced three phase power to be supplied to the grid. This paper presents a geometrical approach to calculate common mode voltage during unequal power level on three phase cluster. The capacitor voltage balancing of individual cluster and cell are also presented during different power level in the cell. Mathematical derivation of common mode voltage based on unequal phase cluster power are also included in the paper. Phase shifted Sinusoidal Pulse width modulation (SPWM) technique is used to operate the CHB multilevel converter. Simulation results of three phase current balancing during non-uniform radiation are verified using Matlab/Simulink.

However, trends related to fitness in India could be the same or different. Hence, the present paper makes an attempt to analyze the latest fitness trends in India. A total of eighteen (18) surveys were shortlisted on the basis of their relevance to the present topic of study and were arranged in descending order of their chronology. Content analysis was done after preliminary set of data collection, which formed the basis of grouping of data. Further, frequency and percentage were used to statistically represent the data. It can be concluded from the analysis of data regarding recent fitness trends in India that yoga dominates the fitness activity list, followed by numerous other activities including running, zumba and sh'bam, boot camp, boxing, kickboxing, cycling, swimming, TRX, ass-pocalypse, ballet, biking, bokwa fitness, dance-iso-bic, masala bhangra, outdoor activities, pilates, planks, push-ups, sofa workouts, stairs Workouts, tabata training, and twerking. The body weight/ gym-specified/ strength training as well as high intensity interval training dominates the preferred workouts; followed by mixed work-outs, cross training work-outs, express work-outs, functional fitness, natural body movements, personalized training, and stay-at-home workouts. General areas that featured in the latest fitness trends in India demonstrates that the fitness is making an impact on all sections of the society be it children, women, older adults, senior citizens, worksite fitness. Fitness is becoming lifestyle of the masses. People are doing exercise for weight-loss, combining diet with exercising; prefer sweating, making groups to participate in fitness activities and wellness programmes. Technology is another area which has a high impact upon the lives of people. They are using wearable technology for workout tracking and following numerous mobile friendly apps. Keywords—Fitness, India, Survey, Trend. INTRODUCTION Lifestyle related health problems evolving from a sedentary existence are a global concern. Health problems like obesity, coronary heart diseases, diabetes, some forms of cancer etc. are affecting more and more countries and their people. In this context, Indians have started placing emphasis on the importance of following a positive lifestyle and are incorporating fitness regimes into their daily routines to counteract the effects of a largely negative lifestyle. Fitness enthusiasts are engaging in various activities like yoga, running, different forms of dancing, combination of dance and exercise etc. to maintain physical fitness. From the ancient to modern times, the nature of fitness activities has varied. Watchers of fitness trends say the road to better health is paved with new possibilities along with some old ones that are poised to make a comeback. Specific exercise routines to suit specific needs are the rage nowadays. The Worldwide Survey of Fitness Trends 2016 based on ACSM worldwide surveys revealed that some trends were embraced again (e.g., educated and certified health fitness professionals) with two additional trends (e.g. flexibility & mobility rollers and smart phones exercise apps) appearing in the list of top 20. As per the worldwide survey, the trends include : wearable technology; body weight training; high-intensity interval training (HIIT); strength training; educated and experienced fitness professionals; personal training; functional fitness; fitness programmes for older adults; exercise; weight loss and yoga; group personal training; worksite health promotion; wellness coaching; outdoor activities; sport-specific training; flexibility and mobility rollers; smart phone exercise Apps; circuit training; core training and outcome measurements. However, trends related to fitness in India could be the same or different. Hence, the present paper makes an attempt to analyze the latest fitness trends in India.


Researchers are in continuous search of better strategies to minimize, if not prevent, the anthropogenic release of toxic heavy metals, such as Cu(II) and Pb(II), into drinking water resources and the natural environment. Herein, we report for the first time the low-temperature combustion synthesis of magnetic chitosan-manganese ferrite in the absence of toxic cross-linking agents and its removal of Cu(II) and Pb(II) from single-component metal solutions. The nonlinear Langmuir model best described the isotherm data, while the nonlinear pseudo-second order model best described the kinetic data, signifying monolayer Cu(II) or Pb(II) adsorption and chemisorption as the rate-determining step, respectively. Adsorption capacities by magnetic chitosan-manganese ferrite obtained for both metals were consistently higher than those by manganese ferrite, indicating that chitosan enhanced the performance of the magnetic adsorbent. The maximum adsorption capacities of magnetic chitosan-manganese ferrite for Cu(II) and Pb(II) were 14.86 and 15.36 mg g−1, while that of manganese ferrite were 2.59 and 13.52 mg g−1, respectively. Moreover, the adsorbents showed superior binding affinity and sorption for Pb(II) than Cu(II) owing to the stronger ability of the former to form inner-sphere complexes with manganese ferrite and magnetic chitosan-manganese ferrite. Finally, thermodynamic studies revealed that the uptake of either Pb(II) or Cu(II) by magnetic chitosan-manganese ferrite was spontaneous and endothermic. The as-prepared adsorbent was characterized for morphology, elemental composition, surface functional sites, and particle size using scanning electron microscopy, energy dispersive spectroscopy, Fourier transform infrared spectroscopy, and dynamic light scattering technique, respectively.


Data produced by on-chip sensors in modern SoCs contains a large amount of information such as occurring faults, aging status, accumulated radiation dose, performance characteristics, environmental and other operational parameters. Such information provides insight into the overall health of a system's hardware as well as the operability of individual modules. This gives a chance to mitigate faults and avoid using faulty units, thus enabling hardware health management. Raw data from embedded sensors cannot be immediately used to perform health management tasks. In most cases, the information about occurred faults needs to be analyzed taking into account the history of the previously reported fault events and other collected statistics. For this purpose, we propose a special structure called Health Map (HM) that holds the information about functional resources, occurring faults and maps relationships between these. In addition, we propose algorithms for aggregation and classification of data received from on-chip sensors. The proposed Health Map contains detailed information on a particular system level (e.g., module, SoC, board) that can be compiled into a summary of hardware health status that in its turn enables distributed hierarchical health management by using this information at a higher level of system hierarchy, thus increasing the system's availability and effective lifetime.

The embodiments of the present invention relate to an adapter upgrade method, mobile terminal, and adapter. The method comprises: a mobile terminal sending to an adapter a number n of data blocks in first upgrade data; the mobile terminal receiving a first response message sent by the adapter according to the n data blocks; if the first response message indicates that the adapter has not received all of the n data blocks, then the mobile terminal determining that the adapter upgrade has failed. In the adapter upgrade method, mobile terminal, and adapter that are provided in the embodiments of the present invention, upgrade data is sent to the adapter by means of the mobile terminal; the adapter receives a certain amount of said upgrade data, then sends confirmation information to the mobile terminal; if, within a certain time, the mobile terminal has not received the confirmation information or the adapter has not received the upgrade data, then the upgrade has failed, and the mobile terminal resends the upgrade data; the accuracy and reliability when the mobile terminal transmits data to the adapter are thus improved.


Recently, VANETs are getting more attraction in both academic and industry settings. One of the challenging issues in this domain is routing algorithms. They become even more challenging, when they get benefit from intelligent solutions to predict the most stable node in the network to communicate with. There are several contributing factors which have influence on this process; including density, velocity, location, and distance. To the best of our knowledge, density, and velocity have the most impact on the precision of an intelligent routing algorithm for VANET. In this paper, we investigate how density along with velocity can affect two major classes of intelligent prediction-based routing algorithms in vehicular networks. These types of algorithms are divided into velocity-based and density-based groups. Different scenarios have been performed through NS2 in order to realize how each category of algorithms can be affected by both velocity and density at the same time. The obtained results are then illustrated in graphs based on delay and packet delivery ratio as routing performance indicators.

Abstract Background The International Myeloma Working Group response criteria require two consecutive assessments of paraprotein levels. We conducted an exploratory analysis to evaluate whether a single response assessment could be a substitute for the International Myeloma Working Group criteria using data from JCOG1105, a randomized phase II study on melphalan, prednisolone and bortezomib. Methods Of 91 patients with transplant-ineligible newly diagnosed multiple myeloma, 79 patients were included. We calculated the kappa coefficient to evaluate the degree of agreement between the International Myeloma Working Group criteria and the single response assessment. Results Based on the International Myeloma Working Group criteria, 11 (13.9%), 20 (25.3%), 36 (45.6%) and 12 (15.2%) patients had stringent complete response/complete response, very good partial response, partial response and stable disease, respectively. Based on the single response assessment, 17 (21.5%), 19 (24.1%), 35 (44.3%) and 8 (10.1%) patients had stringent complete response/complete response, very good partial response, partial response and stable disease, respectively. The kappa coefficient was 0.76 (95% confidence interval, 0.65–0.88), demonstrating good agreement. The single response assessment was not inferior to the International Myeloma Working Group criteria in the median progression-free survival (3.8 and 2.9 years) in stringent complete response/complete response patients, suggesting that the single response assessment was not an overestimation. Conclusions The single response assessment could be a substitute for the current International Myeloma Working Group criteria for transplant-ineligible newly diagnosed multiple myeloma.


The present study assessed that Relationship between 'standing height' (anthropometric measurement) and spiking ability in Volleyball and what the relationship between standing height and spiking ability. Ten University level Volleyball players were taken and measurements their height and subjects were evaluated through Bosco Ergo Jump test for measuring the jumping ability for spiking. The result indicates that standing height and all the jumping ability (Bosco Ergo Jump test battery)were positively correlated which means good height may produce batter jumping ability.


South Africa is a multilingual country with 11 official languages. However, English dominates as the language of access and power and although the Language-in- Education Policy (1997) recommends school language policies that will promote additive bilingualism and the use of learners' home languages as languages of learning and teaching, there has been little implementation of these recommendations by schools. This is despite the fact that the majority of learners do not have the necessary English language proficiency to successfully engage with the curriculum and that teachers frequently are obliged to resort to using the learners' home language to mediate understanding. This research investigates the classroom language practices of six Grade 8 science teachers, teaching science through the medium of English where they and their learners share a common home language, Xhosa. Teachers' lessons were videotaped, transcribed and analysed for the opportunities they offered learners for language development and conceptual challenge. The purpose of the research is to better understand the teachers' perceptions and problems and to be able to draw on examples of good practice, to inform teacher training and to develop a coherent bilingual approach for teaching science through the medium of English as an additional language.


In teaching writing to foreign or second language learners, one of the issues concerning teachers is the amount and types of errors students make in their writings. This paper aims to obtain a clear understanding of types of errors in the writings of Turkish EFL learners by comparing freshman and sophomore students' writing performance. To this end research questions were formulated to see whether there is any significant difference between the participants' grade and their error types in writing. Data were collected through a picture story task consisting of six pictures. The statistical analyses revealed that a) there was not a statistically significant difference between grade groups on the number of t-units and proportion of words per t-unit they wrote in their picture stories, but b) there was a statistically significant difference between grade groups on the number of words they wrote and errors they made.

An Improved PMU Model for Voltage Response in Transient Stability Simulation Adheesh Boratkar Master of Applied Science (M.A.Sc.) Graduate Department of Electrical and Computer Engineering University of Toronto 2019 Large scale power networks are typically simulated only on transient stability analysis (TSA) software. This is sufficient when modelling slow moving ac quantities is of interest and is much faster than using time domain electromagnetic transient programs. However, TSA tools are not capable of modelling the subcycle dynamics well. Since wide-area measurement systems are practically only modelled on TSA software, while evaluating potential phasor measurement unit (PMU) based control schemes, researchers/utilities depend on TSA results to approximate PMU measurements. This is not sufficient to ensure adequate real-world performance. This research focused on creating a test bench for characterising the dynamic performance of PMUs. Using voltage magnitude data from this test bench, an improved PMU model for transient stability simulation has been created. The model achieves fits of over 97% across the test cases it was validated with, which is a substantial improvement over the raw TSA simulation results (63-77% accuracy).


OBJECTIVE
To evaluate the operating properties of endomysial antibodies (EMAs) in the diagnosis of celiac disease and to examine, using a cost minimization model, different strategies used in the diagnosis of celiac disease.

METHODS
A total of 248 EMA results were reviewed and compared with small bowel biopsy results in 66 patients who had undergone both tests. Regression analysis was used to look for predictors of positive EMA results and positive biopsy results. A cost minimization model from a societal perspective was used to evaluate the cost differences among three different strategies.

RESULTS
EMAs had a sensitivity of 95% and specificity of 64%. The only predictor of a positive biopsy result that reached statistical significance was a positive EMA. The strategy of EMA as a diagnostic test for celiac disease was the most expensive strategy, with a cost of $3,174 per patient assessed. The strategy of small bowel biopsy for all patients had a cost of $997, and a strategy of EMA followed by small bowel biopsy for positive patients had a cost of $866 per patient. The results were sensitive to cost of a gluten-free diet, the specificity of the EMA and the cost of a small bowel biopsy.

CONCLUSION
The EMA is best used as a screening test from both a clinical and cost perspective.


Many have commented on the potential of community pharmacy as a health promotion setting, due to accessibility, high level of use, and the respect afforded to pharmacists. Community pharmacy could be a setting through which to address risk and protective health behaviours relevant to Australia's National Health Priority Areas. However, apart from some studies on smoking cessation, there is scant evidence on its involvement in other healthy behaviours. This paper discusses how to increase research and interventions on healthy behaviours in community pharmacy. This includes placing community pharmacy's role within a broader health promotion context, expanding community expectations of pharmacists, and addressing barriers to performing a health promotion role.


With the prevalence of file distribution systems, P2P traffic has caused great challenges to Internet service providers or network operators. The corresponding problems thereby have been a concern for industrial and academic fields. In this paper, we first present a measurement study of torrents and swarms in BitTorrent systems. We find that most swarms suffer from lack of peers and many resource files are shared by multiple trackers. Based on these two observations, we propose a new architecture, named trackers' tracker (T-Tracker) to provide a new way of traffic control for network providers, bringing a little change to current BitTorrent protocol. With T-Tracker, our architecture can provide more peers by merging parallel swarms for the performance improvement of BitTorrent system and provide more choices for biased peer selection of traffic localization schemes. Therefore, quality of BitTorrent service and network utilization can be optimized at the same time. Keywords-BitTorrent; merging swarms; performance improvement; P2P traffic localization.


where u can be interpreted as the velocity field of an incompressible fluid motion, and p is then the associated pressure, the positive constant μ is the viscosity coefficient of the fluid. For simplicity, we consider homogenous Dirichlet boundary condition for the velocity, i.e. u|∂Ω = 0. To easy the understanding, we write the component-wise formulation in two dimensions. Let u = (u, v) and f = (f1, f2). Then equations (1)-(2) consists of three equations −μ∆u+ ∂xp = f1, −μ∆v + ∂yp = f2, ∂xu+ ∂yv = 0.


This article deals with the autosomal dominant human genetic disorder, Neurofibromatosis Type 1 (NF1), and has three main foci. The first is the general principle that substantial advances in understanding the pathogenesis of a genetic disorder can derive from the timely reconsideration of material previously overlooked or otherwise not given its due. There are times when the key to a supposed "mystery" is hiding in plain sight. The second focus is the specific consideration of selected elements of an apparent vitamin D deficiency in NF1. And the third focus of this article reconsiders the mast cell in NF1 pathogenesis, including the potential of NF1 being a "mastocytosis" of sorts, with the prospect of additional grounds for treatment with mast cell blockers, for example, ketotifen.


A trip back to the BBC newsroom means I bump in to a few old colleagues spitting with rage about the way that their bosses have handled the recent 'trust' stories at the BBC.


Constructing optimal event correlation architecture is crucial to large-scale event services. It plays an instrumental role in detecting composite events requested by different subscribers in scalable and timely manner. However, events generated from different sources might have different time and priority requirements. In addition, the network links and correlation servers might have different bandwidth and processing constraints respectively. In this work, we address the problem of optimizing distributed event correlation to maximize the correlation profit (benefit minus shipping and processing cost) of detecting composite events, while at the same time satisfying the network bandwidth, node capacity, and correlation tasks time constrains. We show that this problem is NP-hard and provide a heuristic approximation algorithm. We evaluate our heuristic approach with different network sizes, topologies under different event delivery and detection requirements. Our simulation study shows that the results obtained by our heuristic are close to the upper bound.

A 64-year-old woman with a 23-year history of JAK2 V617F+ essential thrombocythemia and remote splenectomy experienced progression to myelofibrosis in 2011, which was documented by bone marrow biopsy. Five years later, the peripheral blood is leukoerythroblastic, with 35%


SINCE THE APPEARANCE of marxism as an intellectual force hardly a year — in the Anglo-Saxon world since 1945 hardly a week — has passed without some attempt to refute it. The resulting literature of refutation and defence has become increasingly uninteresting, because increasingly repetitive. Marx' work, though voluminous, is limited in size, and it is technically impossible for more than a certain number of original criticisms to be made of it, and most of these have been made long


Reverse micelles (RM) are water nano-inclusions dispersed in organic solvent and surrounded by a detergent monolayer. The size and water content of RM depends on the parameter W0=[H2O]/[detergent], which in experiments can be easily controlled.[1] On the other hand, by varying W0, one can investigate the effects of confinement and hydration on the structure and stability of biomolecules such as peptides, proteins and nucleic acids. Amongst the most widely used detergents to form RM's are the AOT or Aerosol OT (Dioctyl sodium sulfosuccinate) and alkyl polyethylene glycols (of type CiEj), which have charged and neutral polar heads, respectively. In spite of the abundance of experiments, many questions about RM remain to be answered. In particularly, it is not clear how small RM (i.e. with small water content) can favor the conformation confined biomolecules compared to the same biomolecules in large micelle or in bulk water.


Curitiba is a city in south Brazil with an estimated population of 1.8 million inhabitants [3]. The teledensity in this city is over 1.2 cellular for each person and, four players, actually are working with Long Term Evolution (LTE) in the city. However, the quality of the LTE cell coverage has not yet reached the standard of the Third Generation Partnership Project (3GPP) group. Considering the growing demand for better quality of service provided by telecom operators, this study aims to develop a methodology for analyzing the quality of cellular LTE coverage in Curitiba that can easily be extended to any other big city in Brazil, since we consider a dense urban region, in the frequency range of 2600 MHz and a bandwidth of 20 MHz. The methodology includes conducting a proper drive test in a commercial network with the processing of data obtained through the commercial software, as well as developing a spreadsheet to perform a theoretical project for the purpose of comparing and validating the methodology.


Past research has shown that issues vary significantly in their salience across citizens, explaining key outcomes in political behavior. Yet it remains unclear how individual-level differences in issue salience affect the measurement of latent constructs in public opinion, namely political ideology. In this paper, we test whether scaling approaches that fail to incorporate individual-level differences in issue salience could understate the predictive power of ideology in public opinion research. To systematically examine this assertion, we employ a series of latent variable models which incorporate both issue importance and issue position. We compare the results of these different and diverse scaling approaches to two survey data sets, investigating the implications of accounting for issue salience in constructing latent measures of ideology. Ultimately, we find that accounting for issue importance adds little information to a more basic approach that uses only issue positions, suggesting ideological signals for measurement models reside most prominently in the issue positions of individuals rather than the importance of those issues to the individual.


Eleusine indica is a highly competitive and difficult-to-control plant in annual and perennial crops. In Colombia, broad-spectrum herbicides, such as paraquat and glyphosate, have begun to present poor levels of control for this weed. The multiple resistance to glyphosate and paraquat, the increase in herbicide performance with adjuvants (Retenol® and Trend® 90), and alternative herbicides were evaluated in a resistant (R) population of E. indica collected in rice fields, which is rotated with herbicide-resistant (HR) crops. Based on plant mortality, the R population was 9.8 and 7.2 times more resistant than susceptible (S) plants to glyphosate and paraquat, respectively. R plants accumulated 4.2 less shikimic acid and had at least 70% less electrolyte leakage than S plants when they were exposed to glyphosate and paraquat, respectively. Both adjuvants increased the foliar retention of herbicides. In addition, adjuvants also increased the performance of glyphosate effectiveness between 22% and 58% and that of paraquat from 61% to 100%. Alternative herbicides (atrazine, clethodim, imazamox, diuron, flazasulfuron, glufosinate, oxyfluorfen, quizalofop, and tembotrione) provided high levels of control in both populations of E. indica. This is the first case of multiple resistant E. indica confirmed in Colombia. Adjuvants improved the leaf retention and efficacy of glyphosate and paraquat. In summary, the alternative herbicides evaluated in this study should be adopted by Colombian farmers and provide additional herbicide modes-of-action to combat future resistance.


The anti-corrosive properties of sulphadoxine + pyrimethamine (S+P) on the corrosion of pipeline steel in acidic environment were investigated using electrochemical techniques. The results obtained showed an excellent inhibition efficiency which increased with increase in inhibitor concentration. The corrosion inhibition efficiency increased up to 99.04 % at 0.01M S+P and decreased with rise in temperature down to 85.93 % at 333 K and 0.01 M S+P, suggesting a physiosorptive mechanism of adsorption. Also the adsorption data was fitted into Langmuir and Temkin adsorption isotherms, while the inhibitive action was shown to proceed by mixed inhibition mode.


1-Introduction Floods have always been a great cause of loss of life and resources throughout the world. Due to the high rate of population growth and deterioration of natural resources, risk of flooding is increasing day by day. Therefore, watershed management and protective operations are critical issues to control floods in high flood hazard areas. It is not possible to control the floods for the entire basin considering the large extent of the basins. Therefore, in flood control studies, flood contributing areas should be identified and prioritized in order to control the floods with minimum price and maximum performance. In other words, nowadays, instead of focusing on downstream areas under flooding threat, controlling flood generation in upstream flood contributing areas (source areas) using effective flood control activities, is an accepted practice. One of the proper methods to identify and rank flood contributing areas in the sub-basin scale is Unit Flood Response method (UFRM). In this method, firstly the basin is divided into smaller study units (sub-basins), and by using flood routing module of a rainfall-runoff model (such as HEC-HMS model used in this study), contribution of each unit to the peak flood discharge at the basin outlet is determined using an organized one at a time sub-basin elimination procedure. Then, the areas which have the most contribution to the peak outflow of the basin are identified as the flood contributing areas or flood sources. Although UFRM can be used for identifying and ranking flood contributing areas, it faces challenges when it is used in practice for prioritizing the sub-basins in terms of conducting flood control activities. In this study, a new method called Flood Reduction method (FRM) is introduced for spatial prioritization of flood control activities. In order to compare the performance of UFRM with that of the proposed FRM for spatial prioritization of flood control activities, Kardeh basin (located upstream of the Kardeh dam) in the Khorasan Razavi province, Iran was selected as the study area, and the results of prioritizing the sub-basins by the two methods were analyzed and compared. The effect of the design rainfall duration on the prioritization of the sub-basins was also investigated in this study.


Anthropometrics, cytokines [C reactive protein (CRP), interleukin‐6 (IL‐6), tumor necrosis alpha (TNF‐alpha)], leptin, adiponectin, plasma lipids and 24h dietary recalls were analyzed for Latino subjects diagnosed with type 2 diabetes recruited from the DIALBEST trial (n = 22 men and 60 women, 32‐76y). Parameters were measured at baseline (BL) and after 3 and 6 mo of intervention. Subjects were randomly assigned to a peer counseling (PC) or a control group (CG) receiving the standard of care from Hartford Hospital. There were no changes in macronutrient intake over time except for total and soluble fiber, which were increased between baseline and 6 mo by 7 and 12% in the PC group and decreased by 35 and 29%, respectively in the CG (P < 0.05). IL‐6 decreased by 20% in all subjects between baseline and 6 mo (P < 0.01). However, when the group was divided on the basis of statin use, only those subjects prescribed a reductase inhibitor decreased IL‐6 over time (p=0.01). No changes were observed in CRP, leptin, adiponectin or TNF‐alpha levels over time or between groups. There was a negative correlation between changes in HDL cholesterol and CRP between baseline and 6 months (r = ‐0.297, P < 0.05) and a positive correlation between adiponectin and HDL at 6 mo (r = 0.363, P < 0.01). The data suggest that both statins and HDL play an important role in improving inflammation in this population. In addition, PC did not affect inflammatory markers in this population.

The National Science Education Standards encourage teachers to become involved in research as 'representatives of science in the classroom'. The Research Experiences for Teachers program affiliated with the Materials Research Science and Engineering Center at the University of Nebraska involves teachers in research on nanoscale magnetic and electronic structures over a summer. Two teachers and a sponsoring researcher share their experiences and what they believe are necessary elements for successful RET experiences.


Abstract : The nucleonic intensity observations at Thule, Greenland have established an apparently longer data base than any other station in either polar cap. During the brief period covered by this report, significant progress has been made toward understanding three important phenomena: (1) the origin of transient cosmic ray intensity variation; and (2) the mechanism that is responsible for producing north-south anisotropy and acceleration of relativistic cosmic rays between converging interplanetary shock waves. These results are described in detail. (Author)

Tourism does provide many economic benefits that trigger an increase in the quality of the social environment and the strengthening of cultural values as a commodity. However, these benefits are not always consistent with sustainable management. In this article, the research gap focused on how local communities in managing sustainable tourism. In-depth surveys and interviews conducted in three local communities who manage travel in the National Tourism Strategic Area (KSPN) Ijen Baluran, which includes Situbondo, Banyuwangi, and Bondowoso. The analysis showed that the ability of communities in managing sustainable tourism relies heavily on the experience of interacting with tourists outside the area, government support and partner network. Interaction with tourists outside the area will provide a social exchange about the expectations of travelers or travel trend is growing. Interaction and social exchange to be a catalyst in accelerating the achievement of sustainable tourism management.


To improve water quality particularly for sea bathers along the Fylde coastal zone near Blackpool, North West England, waste water from a sewage outfall is studied using a mathematical model. The explicit second order accurate central scheme and the third order accurate QUICKEST scheme are used to represent the diffusion terms and the advection terms of the advective-diffusion equation, respectively. Hydrodynamic model is run for a coarse and fine grid, of 1㎞ and 200m, respectively, obtaining good agreement with measured data. Water quality model is then used to predict faecal coliform levels in the region for four different scenarios, including discharges from: (ⅰ) Fleetwood outfall, (ⅱ)River Ribble for summer condition, (ⅲ)River Ribble for winter condition, and (ⅳ)combined sewer overflows for the Blackpool and Fleetwood communities. Main findings from the simulations are:- (ⅰ) Fleetwood outfall has a negligible impact on the beaches with respect to pathogen levels; (ⅱ) Discharge from River Ribble for both summer and winter conditions is predicted in the range of coliform levels 10 -00 counts/100㎖ along the beach at Lytham St. Annes; and (iii) The csa effluent discharges are predicted not to advect out into offshore by stronger tidal currents.

Basic fibroblast growth factor (bFGF) is a growth factor that is involved in cell proliferation, differentiation, and angiogenesis (1). It has long been known that bFGF acts as a powerful mitogen for various mammalian granulosa cells in culture (2). To investigate the possible involvement of bFGF expression in follicle initiation and growth, quantitative PCR on isolated human follicle populations was performed. Human ovarian biopsies were obtained from healthy fertile women undergoing tubal ligation. Oocytes and granulosa cells of follicles at different stages of growth were isolated with laser capture microdissection in RNase-free conditions. Follicles were characterized as primordial, primary, small secondary, large secondary or antral, using morphological criteria. Owing to the very small amounts of tissue retrieved for primordial and primary follicles, these samples were pooled for each patient. RNA was extracted from samples, reverse transcribed, and relative quantitation determined with TaqMan real-time PCR, using 18S rRNA as the endogenous control. The probe and primers for human bFGF were commercially available in a pre-developed assay mix (Assays-on-Demand: ABI). Preliminary results suggest an upregulation of bFGF mRNA expression with increasing follicle growth. This study demonstrates that a possible relationship exists between bFGF mRNA expression and follicle development. (1) Gospodarowicz, D. et al. (1986) Mol. Cell. Endocrinol. 46: 187–204.

The accuracy of known test methods in determining the reliability of PVC cable components is compared. It is shown that express methods do not give satisfactory results; a new standard method must be developed for testing any kind of filled or unfilled PVC compound. The basic principles of such a method are outlined


Uncertainty is ubiquitous in practical engineering and scientific research. The uncertainties in parameters can be treated as interval numbers. The prediction of upper and lower bounds of the response of a system including uncertain parameters is of immense significance in uncertainty analysis. This paper aims to evaluate the upper and lower bounds of magnetic vector potentials in a linear magnetostatic field efficiently with uncertainbut-bounded parameters. The uncertain-but-bounded parameters are represented by interval notations. By performing Taylor series expansion on the magnetic vector potentials obtained from the equilibrium governing equation and by using the properties of interval mathematics, we can calculate the upper and lower bounds of the magnetic vector potentials of a linear magnetostatic field. In order to evaluate the accuracy and efficiency of the proposed method, two numerical examples are used. The results illustrate that the precision of the proposed method is acceptable for engineering applications, and the computation time of the proposed method is significantly less than that of the Monte Carlo simulation, which is the most widely used method related to uncertainties. The Monte Carlo simulation requires a large number of samplings, and this leads to significant runtime consumption.


Calculating vibrational properties of crystals using quantum mechanical (QM) methods is a challenging problem in computational material science. This problem is solved using complementary machine learning methods that rapidly and reliably recapitulate entropy, specific heat, effective polycrystalline dielectric function, and a non‐vibrational property (band gap) for materials calculated by accurate but lengthy QM methods. The materials are described mathematically using property‐labeled materials fragment descriptors. The machine learning models predict the QM properties with root mean square errors of 0.31 meV per atom per K for entropy, 0.18 meV per atom per K for specific heat, 4.41 for the trace of the dielectric tensor, and 0.5 eV for band gap. These models are sufficiently accurate to allow rapid screening of large numbers of crystal structures to accelerate material discovery.


Electromagnetic wave propagation in the cavity with anisotropic hyperbolic metamaterial based on gold nanowires tilted relatively to outer boundary are investigated. The transfer matrix method was adopted for arbitrary orientation of optical axis according to slab boundary using $4\text{x}4$ Berreman matrix. We have estimated the effect of increasing of density of photonic states of electromagnetic field in the cavity by direct calculation of modal field and the roots of dispersion equation. The possibility of super-Planckian thermal emission is discussed.
