Full Text Available This paper as a synthetic analyzis based on the Markowitz and Sharpe models deals with the problem of portfolio trying to determine both the optimum proportion of titles and the influence of a considered macroeconomic factor over their level of efficiency and risk. The improvement of these models was made through the introduction of a new model, the APT model (Arbitrage Price Theory, as a development of the uni-factorial CAPM model, in other words, the above-mentioned model only constitutes a particular form of the APT model trying to establish a relationship between the individual efficiency of a title from the portfolio and several macroeconomic factors. Also, this model involves the identification of macroeconomic factors influencing the profitability of the titles and the determination of the influence of these factors individually, through the application of the APT model.

Full Text Available Background: This article analyses case descriptions of child suicides from 2004 to 2012 toinform future policy and practice. Methods: Quantitative data and case descriptions for 159 child suicides (under 18 years in Queensland, Australia, were analysed quantitatively using SPSS and qualitatively using automated content analyzis (Leximancer. Results: More than three quarters of child suicides involved hanging and 81% of suicides occurred in the family home. Less than 20% of the deceased left a note, however there was evidence of planning in 54% of cases. Most common triggering events were family conflicts. Conclusions: Effective suicide prevention interventions require a comprehensive understanding of risk factors. Quality of case descriptions varied widely, which can hamper injury prevention efforts through an incomplete understanding of characteristics of, and important factors in child suicide. Additional attention and resources dedicated to this public health issue could enhance the development and implementation of effective intervention strategies targeting child and adolescent suicide.

The knowledge of coefficient of soil decontamination is necessary for predictions the dynamics in development of radioactive situation, for retrospective estimation and reconstruction of the initial radioactive contamination levels of territories. By effective coefficient of soil decontamination from radionuclides (CSD) we mean the multiple of a nuclide completely removed from the soil as a result of its physical decay, active removal of radionuclides from the ground into water ecosystems, as well as biogeochemical and wind migration beyond KURT borders. Its dimension can be expressed in the divisible relation (in how many times?), in percentage, as well as in periods of half-desintegration, if the process of desintegration is the exponent. The calculation is made on a complete nuclides supply in soil. The objective of the study is to calculate the effective coefficient of soil decontamination from 90 Sr on the basis of the analyzis of the experimental materials received at KURT territories in Sverdlovsk region.

2D PIV and LIF measurements have been performed on buoyancy driven flows of two miscible fluids of the same viscosity in a tube tilted at different angles θ from vertical and at different density contrasts (characterized by the Atwood number At). As θ increases and At decreases, the flow regime evolves, behind the front, from a turbulent shear flow towards a laminar counter flow with 3 layers of different concentrations. Time variations of the structure function show that both intermittent and developed turbulence occur in intermediate conditions. In the turbulent regime (Reλ˜60) the magnitudes of the longitudinal u'^2 and transverse v'^2 velocity fluctuations and of the component u'v' of the Reynolds stress tensor are shown to be largest on the tube axis while viscous stresses is only important close to the walls. The analyzis of the momentum transfer in the flow with buoyancy forces estimated from the concentration gradients demonstrates that 3D effects are required to achieve the momentum balance. These results are discussed in the framework of classical turbulence models.

Full Text Available Purpose: The main purpose of this study was to compare the phenomenon of interfrm cooperation strategy in both hyper-growth, and stable-growth knowledge and technology–intensive frms, in a country characterized by a high level of generalized trust: Sweden. Methodology: Qualitative methods were incorporated: direct semistructured interviews with top managers in 13 ICT frms (8 hyper-growth and 5 stable-growth, analyzis of reports, corporate websites and press releases. Furthermore, interviews in 3 expert frms in the industry were conducted, facilitating interfrm cooperation. Conclusions: There were signifcant differences in interfrm cooperation strategy in two distinguished groups of the frms: hyper-growth, and stable-growth. Managers’ individual approaches to uncertainty, strategy and cooperation might be more important than institutional settings. The ICT frms operate in a constantly changing global environment and local context seems to have only a minor impact on the rules of the game in the industry. Research limitations: This study was a qualitative explorative approach as an introduction to further empirical research. Originality: The study presents an interfrm cooperation phenomenon incorporating different perspectives and settings. It contributes to alliance portfolio literature (forming and managing of alliance portfolio in a different context/country/industry, and enhances understanding of frm strategies characterized by different growth rates.

ClusTrack: feature extraction and similarity measures for clustering of genome-wide data sets.

Directory of Open Access Journals (Sweden)

Halfdan Rydbeck

Full Text Available Clustering is a popular technique for explorative analysis of data, as it can reveal subgroupings and similarities between data in an unsupervised manner. While clustering is routinely applied to gene expression data, there is a lack of appropriate general methodology for clustering of sequence-level genomic and epigenomic data, e.g. ChIP-based data. We here introduce a general methodology for clustering data sets of coordinates relative to a genome assembly, i.e. genomic tracks. By defining appropriate feature extraction approaches and similarity measures, we allow biologically meaningful clustering to be performed for genomic tracks using standard clustering algorithms. An implementation of the methodology is provided through a tool, ClusTrack, which allows fine-tuned clustering analyses to be specified through a web-based interface. We apply our methods to the clustering of occupancy of the H3K4me1 histone modification in samples from a range of different cell types. The majority of samples form meaningful subclusters, confirming that the definitions of features and similarity capture biological, rather than technical, variation between the genomic tracks. Input data and results are available, and can be reproduced, through a Galaxy Pages document at http://hyperbrowser.uio.no/hb/u/hb-superuser/p/clustrack. The clustering functionality is available as a Galaxy tool, under the menu option "Specialized analyzis of tracks", and the submenu option "Cluster tracks based on genome level similarity", at the Genomic HyperBrowser server: http://hyperbrowser.uio.no/hb/.

A point of view on Otto cycle approach specific for an undergraduate thermodynamics course in CMU

Memet, F.; Preda, A.

2015-11-01

This paper refers to the description of the way in which can be presented to future marine engineers the analyzis of the performance of an Otto cycle, in a manner which is beyond the classic approach of the course of thermodynamics in Constanta Maritime University. The conventional course of thermodynamics is dealing with the topic of performance analysis of the cycle of the internal combustion engine with isochoric combustion for the situation in which the working medium is treated as such a perfect gas. This type of approach is viable only when are considered relatively small temperature differences. But this is the situation when specific heats are seen as constant. Instead, the practical experience has shown that small temperature differences are not viable, resulting the need for variable specific heat evaluation. The presentation bellow is available for the adiabatic exponent written as a liniar function depending on temperature. In the section of this paper dedicated to methods and materials, the situation in which the specific heat is taken as constant is not neglected, additionaly being given the algorithm for variable specific heat.For the both cases it is given the way in which it is assessed the work output. The calculus is based on the cycle shown in temperature- entropy diagram, in which are also indicated the irreversible adiabatic compression and expansion. The experience achieved after understanding this theory will allow to future professionals to deal successfully with the design practice of internal combustion engines.

To describe how public prosecutors self-assess their communication approaches and how listeners react to them; to analyze how this relates to gender, age, and work experience. Descriptive, transversal study. A questionnaire was developed and sent to 126 public prosecutors for completion. Thirty-three completed questionnaires were sent back. The independent variables were gender, age, and number of years of professional experience. The dependent variables were communication self-assessment throughout the years of work, communication parameters used, and listeners' reactions. A descriptive analyzis and Fisher's Exact Test was carried out. the sample contained both male and female participants with a median age of 43 years and an average of 20 years of professional experience. Most of the respondents claimed they had experienced demotivation, insecurity, tension, and difficulty when trying to convince listeners. More women than men reported they felt that their communication had worsened throughout their careers. All the women reported they experienced insecurity when speaking in public. One third of the public prosecutors stated they suffered from disorders on their voice. Those respondents aged over 43, experienced greater proportion on voice change than younger ones. In contrast to their younger colleagues, the majority of public prosecutors with more than 20 years of professional experience revealed that they felt insecure when speaking in public. the public prosecutors identified their strong and weak communication parameters. Gender, age, and work experience affect communicative performance.

It provide a basis for gene regulate the formation of L. japonica floral scents. The cDNA and genome sequences of LjSABATHMT from L. japonica var. chinensis were cloned according to the gene fragments in cDNA library. The LjSABATHMT protein was characterized by bioinformatics analysis. SABATH family phylogenetic tree were built by MEGA 5.0. The transcripted level of SABATHMT orthologous were analyzed in different organs and different flower periods of L. japonica and L. japonica var. chinensis using RT-PCR analysis. Intron sequences of SABATHMT orthologous were also analyzied. The cDNA of LjSABATHMT was 1 251 bp, had a complete coding frame with 365 amino acids. The protein had the conservative SABATHMT domain, and phylogenetic tree showed that it may be a salicylic acid/benzoic acid methyltransferase. Higher expression of SABATH methyltransferase orthologous was found in flower. The intron sequence of L. japonica and L. japonica var. chinensis had rich polymorphism, and two SNP are unique genotype of L. japonica var. chinensis. The motif elements in two orthologous genes were significant differences. The intron difference of SABATH methyltransferase orthologous could be inducing to difference of gene expression between L. japonica and L. japonica var. chinensis. These results will provide important base on regulating active compounds of L. japonica.

A survey of chest medical X-ray doses

Lomba, M.; Conha, P.G. da; Almeida, C.E. de

1996-01-01

The medical X-ray exposures due to radiological examinations are responsible for the largest contribution to the population collective dose as result of the normal use of artificial sources of radiation. The relative impact of the medical exposures to the total dose received by the population from all kinds of radiation sources varies from country to country and in some cases within the same country. The dose variations observed for a specific type of examination are in general associated to several factors i.e. the type of film-ecran combination, the choice of the appropriate physical parameters of the X-ray generator (Kvp, filament current, exposure time) and finally to the film processing conditions. At the present moment the data available in Brazil are scarce and scanty to allow a complete analyzis of this question so needed by the health authorities to justify the implementation of a quality assurance and dose reduction programs. In addition, it is desirable to establish a cost effective operation based on simple administrative concepts in order to reduce the number of films retake, then increasing the life expectancy of the equipment and the number of radiological procedures. The aim of this work was to assess the typical doses of an PA and LAT chest wall X-ray examinations in five different public hospitals (a University Hospital, a Cancer Hospital, a Navy Hospital, an Emergency Hospital and a State General Hospital), as representative of the city of Rio de Janeiro, and compare the results with the international data and recommendations available.

Joint Economic Lot Sizing Optimization in a Supplier-Buyer Inventory System When the Supplier Offers Decremental Temporary Discounts

Directory of Open Access Journals (Sweden)

Diana Puspita Sari

2012-02-01

Full Text Available This research discusses mathematical models of joint economic lot size optimization in a supplier-buyer inventory system in a situation when the supplier offers decremental temporary discounts during a sale period. Here, the sale period consists of n phases and the phases of discounts offered descend as much as the number of phases. The highest discount will be given when orders are placed in the first phase while the lowest one will be given when they are placed in the last phase. In this situation, the supplier attempts to attract the buyer to place orders as early as possible during the sale period. The buyers will respon these offers by ordering a special quantity in one of the phase. In this paper, we propose such a forward buying model with discount-proportionally-distributed time phases. To examine the behaviour of the proposed model, we conducted numerical experiments. We assumed that there are three phases of discounts during the sale period. We then compared the total joint costs of special order placed in each phase for two scenarios. The first scenario is the case of independent situation – there is no coordination between the buyer and the supplie-, while the second scenario is the opposite one, the coordinated model. Our results showed the coordinated model outperform the independent model in terms of producing total joint costs. We finally conducted a sensitivity analyzis to examine the other behaviour of the proposed model. Keywords: supplier-buyer inventory system, forward buying model, decremental temporary discounts, joint economic lot sizing, optimization.

Examination of X-ray spectra from the antiprotonic helium isotopes 3He and 4He

International Nuclear Information System (INIS)

Schneider, M.

1987-05-01

Using the high intensity antiprotonic LEAR beam at CERN (Geneva), several measurements were done to investigate the X-ray spectra of the antiprotonic Helium isotopes 3 He and 4 He. For the first time antiprotons were stopped in gases at low pressures (600, 375, 72 and 36 mbar), which permitted observations on nearly isolated atoms. A newly developed method for stopping the antiprotons in gases by means of a focusing cyclotron field surrounding the target gas was used. The field was supplied by a superconducting magnet ('cyclotron trap'). The antiprotons were tangentially injected into the cyclotron field, where they slowed down by ionising the target gas. The inhomogeneous magnetic field guided the antiprotons in spiral orbits to the magnetic center. Thus, even at low pressures a very small stopping volume could be achieved. To detect the X-rays different Si(Li)- and Ge-semiconductor detectors were used, some of which were furnished with 'guard-rings'. They were used to investigate the effects of the strong interaction between the antiproton and the nucleus in the (3d → 2p) transition in both isotopes. The analyzis of this transition permitted directly the determination of the shift and width of the 2p-level. The width of the 3d-level could be determined only indirectly using an intensity balance. The utilization of gases with different pressures permitted investigations of the pressure dependence of the antiprotonic deexcitation process. The results for the widths and shifts were compared with earlier measurements and theoretical predictions. The theory agrees only partly with the measurements. The evaluation of a complex scattering length using an optical model contradicts some of the results of calculations. (orig.) [de

[Acoustic conditions in open plan office - Application of technical measures in a typical room].

Mikulski, Witold

2018-03-09

Noise in open plan offices should not exceed acceptable levels for the hearing protection. Its major negative effects on employees are nuisance and impediment in execution of work. Specific technical solutions should be introduced to provide proper acoustic conditions for work performance. Acoustic evaluation of a typical open plan office was presented in the article published in "Medycyna Pracy" 5/2016. None of the rooms meets all the criteria, therefore, in this article one of the rooms was chosen to apply different technical solutions to check the possibility of reaching proper acoustic conditions. Acoustic effectiveness of those solutions was verified by means of digital simulation. The model was checked by comparing the results of measurements and calculations before using simulation. The analyzis revealed that open plan offices supplemented with signals for masking speech signals can meet all the required criteria. It is relatively easy to reach proper reverberation time (i.e., sound absorption). It is more difficult to reach proper values of evaluation parameters determined from A-weighted sound pressure level (SPLA) of speech. The most difficult is to provide proper values of evaluation parameters determined from speech transmission index (STI). Finally, it is necessary (besides acoustic treatment) to use devices for speech masking. The study proved that it is technically possible to reach proper acoustic condition. Main causes of employees complaints in open plan office are inadequate acoustic work conditions. Therefore, it is necessary to apply specific technical solutions - not only sound absorbing suspended ceiling and high acoustic barriers, but also devices for speech masking.
