DMFT index and oral mucosal lesions associated with HIV infection: cross-sectional study in Porto Velho, Amazonian region - Brazil
Aleixo, Rodrigo Queiroz;Scherma, Alexandre Prado;Guimar?es, Gustav;Cortelli, José Roberto;Cortelli, Sheila Cavalca;
Brazilian Journal of Infectious Diseases , 2010, DOI: 10.1590/S1413-86702010000500005
Abstract: we evaluated the dmft (decayed, missing and filled teeth) index and the prevalence of candidiasis, linear gingival erythema, oral hairy leukoplakia, herpes simplex, aphthous ulcers, kaposi's sarcoma and lymphoma, as well as the association with tcd4 count, viral load (vl) and antiretroviral therapy (art) in 140 hiv-infected adult individuals. a standardized examination to determine the dmft index and the presence of oral lesions was conducted. demographic data, tcd4 count and use of art were obtained from medical records. a high number of decayed teeth detected among patients undergoing art resulted in a mean dmft of 16.9 teeth. it was observed that 24.2% of the individuals had at least one oral lesion. candidiasis was the most frequent lesion and was associated with the tcd4 count. oral hairy leukoplakia was associated with an increased vl. regular use of art was inversely associated with the occurrence of lesions. overall, the studied population showed low prevalence of oral lesions and high dmft index. the use of art seems to reduce the occurrence of these lesions. higher tcd4 count and a lower vl were associated with an improved oral health status in hiv + individuals
Theoretical and Practical Notes on Vending Strategies  [PDF]
Gustav Cepciansky, Ladislav Schwartz
iBusiness (IB) , 2011, DOI: 10.4236/ib.2011.31001
Abstract: The paper deals with an application of theory of mass servicing on some cases in vending strategies. The aim of the paper is to show how the theory which is apparently applicable for scientific problems can also be utilised in practical use. First, the necessary theoretical background will have been done and then some examples applied on vending practises will be given.
Tariffication Strategies and Charging Effectivity  [PDF]
Gustav Cepciansky, Ladislav Schwartz
iBusiness (IB) , 2011, DOI: 10.4236/ib.2011.33041
Abstract: The effort of all service providers is to maximize their revenues. The ideal case would be, when a service provider obtained payment for entire services provided. But it is not always possible. Some services may not be paid for. Distribution companies (electricity power, gas, and water), transport companies (airlines, railways, buses, and taxis), telecommunication companies and companies established by the government (e.g. cash of road tax) represent such type of enterprises. Their clients pay for the volume of drawn media, distance of transmission, service duration, amount of transmitted information or travelled distance. Most services are charged fully, but certain services are only charged partly or not at all. An appropriate theory concerning the service provision effectivity and charging policy will be done on examples from telecommunication business and from road tax cashing.
Concatenated Processes in Commercial Business and in Global Economy  [PDF]
Gustav Cepciansky, Ladislav Schwartz
iBusiness (IB) , 2012, DOI: 10.4236/ib.2012.44037
Abstract: The paper deals with an application of theory stochastic processes on business practices and with consequences which the concatenated economic co-operation may have on the future economic growth. The aim of the paper is also to draw attention how the theory which is apparently applicable for solution of scientific problems can also be utilised in practical commercial and economic use. First, the necessary theoretical background will have been done and then some application examples will be given.
Headache in ER
Pietro Cortelli,Marco Aguggia
Emergency Care Journal , 2007, DOI: 10.4081/ecj.2007.4.8
Abstract: In evaluating a headache patient, the first task is to identify or exclude secondary headaches based on the history, and the general medical as well as neurological examinations. Physical and neurological examinations are mandatory, overall in emergency room setting. If suspicious features are present, diagnostic testing may also be necessary. Once secondary headaches are excluded, the task is then to diagnose one more specific primary headache disorder. We summarize some typical emergency room situations in which headaches must be differentiate and treated.
A Note on Factor Prices and Technical Progress  [PDF]
Carl-Gustav Melén
Technology and Investment (TI) , 2011, DOI: 10.4236/ti.2011.23021
Abstract: Changes in the factor prices have important impacts on characteristics of investments, such as the expected lifetime, the factor intensity and the factor productivity of new capital goods. Considering both changes in factor prices as well as technical progress, different effects arise at either high substitutability or low substitutability in production. It can be shown that for a production function close to the Cobb-Douglas case, higher interest rates and technical progress will decrease the expected lifetime, the capital intensity and productivity, while the reversed outcome occurs at lower substitutability between factor inputs.
The Elasticity of Substitution and Characteristics of New Investments  [PDF]
Carl-Gustav Melén
Modern Economy (ME) , 2012, DOI: 10.4236/me.2012.32021
Abstract: Changes in the interest rate and the capital cost will influence important characteristics of investments, such as the expected life time, the factor intensity and the factor productivity of new capital goods. When Harrod-neutral technical progress is endogenous and variable, an increased interest rate will lower the lifetime as well as the factor intensity of the capital good in the Cobb-Douglas case, while there will be a reversed outcome when the substitutability between factor inputs is low. The latter outcome can be interpreted in terms of a reswitching process, that is, one identical factor intensity can arise at two different factor price ratios.

Scanning of Markov Random Processes
Gustav Cepciansky
Advances in Electrical and Electronic Engineering , 2003,
Abstract: Function of most electronic devices is based on the microprocessor control. A microprocessor must scan and evaluate function of many controlled equipment that can be transformed into 2 statuses - "free" or "busy". Microprocessors in a digital exchange are the typical example of that. It can be said the microprocessors are in a discrete dialogue with the controlled parts. They ascertain in regular time intervals whether the status of the controlled equipment has changed. 1 or more "busy" statuses may exist in the same time. As the changes from "free" to "busy" and from "busy" to "free" occur randomly, the state of i busy statuses lasts for a random period too. If the changes have pro-perties of Markov process, the probability which each change will be detected with and hence the scanning rate needed can be derived.
Transitons of Markovian Process Through a Given Level
Gustav Cepciansky
Advances in Electrical and Electronic Engineering , 2003,
Abstract: This paper is a free continuation of [l] where properties of Markovian process were also dealt with. It may be necessary to determine the count of transitions through a given level and the mean time during that the random process persists over or below a chosen level. Traffic load estimations and predictions in dynamically controlled broadband networks may serve as an example of practical applications. Unlike of [l] where as many changes in the state of random process as possible shall be caught up, now we are only interested in those transitions which cross a chosen level.
