Authors: PINTO Tatiana Andréia Soares , QUADROS Onofre Francisco de , RADOS Pantelis Varvaki
Published: September 2019

Leucoplasia é um termo clínico que se refere a uma alteração localizada nas mucosas, com aspecto de mancha ou placa branca firmemente aderida, não removida por raspagem. Essa lesão pode apresentar áreas eritroplásicas e é considerada cancerizável devido ao risco de transformação maligna. Assim sendo, é necessário o estabelecimento do diagnóstico correto e precoce, além do tratamento adequado para prevenção do câncer bucal. A citopatologia é um exame baseado na observação microscópica de células obtidas por raspagem da mucosa. O controle periódico dos pacientes que apresentam leuclopasias é extremamente importante, e pode ser realizado através da citopatologia. O presente trabalho tem como objetivo revisar a literatura sobre o tema leucoplasia e apresentar um caso clínico em que foi realizado o estudo citopatológico pré-biópsia e o seu acompanhamento nos primeiros 3 meses pós-operatórios.

Published: September 2019

O objetivo deste estudo foi avaliar “in vivo” o efeito da utilização das lâmpadas halógenas como catalisadoras de um gel à base de peróxido de hidrogênio a 37,5% utilizado para o clareamento dental em consultório. Treze pacientes foram submetidos ao tratamento clareador em consultório com peróxido de hidrogênio a 37,5% (Whiteness HP Maxx, FGM/ Joinvile, SC, Brasil). A arcada superior de cada paciente foi dividida, e então em um dos hemiarcos o tratamento clareador foi realizado com a aplicação do peróxido de hidrogênio associado à iluminação com lâmpada halógena e no outro hemiarco o peróxido de hidrogênio foi utilizado sem nenhuma fonte de luz. Fotografias pré e pós operatórias foram realizadas nas mesmas condições de iluminação e submetidas à análise através de um software para comparar o grau de clareamento obtido nos hemiarcos esquerdo e direito. Os dados foram analisados utilizando o teste de t-student (p?0.05). Os resultados mostraram que não houve diferença significativa no clareamento obtido quando as duas técnicas foram comparadas. Estes resultados possibilitaram concluir que a iluminação com lampadas halógenas não melhorou o resultado final da técnica de clareamento dental em consultório quando um gel à base de peróxido de hidrogênio a 37,5% foi utilizado.

Os dentes supranumerários constituem uma das anomalias mais conhecidas e estudadas da dentição humana. Essa alteração, também conhecida como hiperdontia, representa a formação de um ou mais dentes em número maior que o normal, podendo ocorrer em ambos os arcos dentários. O diagnóstico normalmente é realizado a partir de exames radiográficos convencionais, principalmente com a radiografia panorâmica, e em alguns casos com o uso da tomografia computadorizada. No presente trabalho foram avaliadas 1.325 radiografias panorâmicas de pacientes atendidos no serviço de Radiologia do curso de Odontologia da Universidade Federal do Ceará, residentes em Fortaleza, no período de outubro de 2007 a dezembro de 2008, com o objetivo de avaliar a prevalência de molares supranumerários. Assim, foram encontrados 25 pacientes que apresentaram molares supranumerários, sendo 13 homens e 12 mulheres, entretanto não sendo observada diferença estatisticamente significante (p=0,5264). Houve uma ocorrência mais comum na maxila do que na mandíbula. Conclui-se que os molares supranumerários apresentaram uma considerável prevalência na população examinada, reforçando a importância do diagnóstico precoce de tal anomalia dentária, a fim de se realizar o tratamento, se necessário.

Published: September 2019

Introduction: One of the most commonly used methods of waste management is landfilling, which has been a major environmental concern. Objective: To examine the effect of leachate on Clarias gariepinus. Methods: We tested Clarias gariepinus (n=700) with varying concentrations of leachate (0, 10, 15, 20 and 25%) from the Amoyo dumpsite, Ilorin, Nigeria. After 28-day exposure, haematological, biochemical, bacteriological and histopathological assays were carried out. Results: pH ranged from 7,78 to 13,97; cadmium, iron, lead, manganese and zinc were 178-, 134-, 6248-, 400- and 3-fold, respectively, higher than the regulatory limits for waterbodies, while copper fell within the limits. Values of red blood cell, haemoglobin, packed cell volume, mean cell volume, mean cell haemoglobin, mean cell haemoglobin concentration, lymphocytes and monocytes were significantly lower than the control. Conversely, white blood cell, neutrophils and eosinophils increased in a concentration-dependent manner. There were tissue-specific differences in the responses of all biochemical parameters investigated except for protein that significantly decreased in all the tissues. veitisiete bacterial isolates classified into seven genera including Bacillus, Klebsiella, Pseudomonas, Staphylococcus, Acinetobacter, Escherichia and Micrococcus were recorded from the leachate and selected organs of C. gariepinus. The total bacterial, viable coliform and total counts in the leachate were 4,2×106CFU/mL, 3,8×108CFU/mL, 3,6× 106CFU/mL and 2,7×108CFU/mL, respectively. The highest counts were recorded in the gills (14,2×106CFU/mL) and lowest in the muscle (2,7×106CFU/mL) at the highest and least concentration of the leachate, respectively. Most of the bacteria isolated from the leachate were also recovered from the fish organs. Escherichia coli had the highest frequency of occurrence (26%). Conclusion: This study revealed that toxic constituents of the leachate elicited deleterious changes in the bacteriology and physiology of C. gariepinus.

Published: September 2019

In this paper, our purpose is to examine the relationship between the role of Internal Audit (IA), Corporate Governance (CG) and the Audit Committee (AC) in the recent financial crisis in Greece and to investigate the contribution of IA to CG structures as well as its possible, the IA’s role during the financial crisis in Greece. Moreover, little research has been conducted based on the relationship between corporate governance and internal audit during the financial crisis in case of Greece. For this reason, we conducted a survey, using questionnaires, which were sent to the listed companies of the Athens Stock Market. Out of a total of 192 listed companies on the Athens Stock Exchange, the relevant questionnaires were sent to 100 companies. Those companies were selected firstly based on their total turnover and secondly due to the availability of information from company websites such as employees’ numbers and Internal Audit Department Structures. Our conclusion was that Internal Audit adds value to the organization and it can also help the senior management towards the accomplishment of the organizational goals.

Paper presents the problem of heating the damaged insulation of an orbiter.
Changes of the insulation?s thermal properties, made by adding conductive
material of high value of specific heat in a form of a dope to the
protective layer, were examined. An iterative algorithm determining a
variable of dope concentration in the material was developed. Insulating
material LI900 was used for calculations. Determination of distribution of
conductive material concentration was made for materials which, after
verification, demonstrated the most beneficial effect on protective
properties of the modified insulation layer. Change of properties was to
enable time extension of the LI900 insulation tile heating up to the maximal
temperature and, additionally, to lowering this temperature.
Performance of thermal insulation fabricated by rapid prototyping technology
Authors: Tychanicz-Kwiecien Maria , Smusz Robert , Gil Pawel
Published: September 2019

Nowadays, 3-D printing technology is very often applied in industry due to
design cycles shortening and surface quality improvement when comparing to
conventional manufacturing technologies. In order to adapt 3-D printed
materials as thermal barriers, it is necessary to determine its
thermophysical properties. As far as thermal insulation is concerned, the
lowest thermal conductivity is required and therefore the crucial parameter
of the material is the porosity. This paper presents the results of
experimental investigation of effective thermal conductivity of thermal
barriers with variable porosity fabricated by the fused filament
fabrication technology. Also the numerical study was presented. The
commercial code - COMSOL multiphysics was used to model the coupled heat
transfer. The model was than validated by comparing the numerical and
experimental results. For each sample the density and thermal conductivity
were determined experimentally. The influence of the size and shape of the
cell on the formation of free convection was investigated in particular. The
effect of the conduction and radiation on temperature and velocity profiles
within the enclosure has been analyzed. In addition, the dominant heat
transfer mechanisms as a function of density have been identified.
Increase of thermal efficiency of cogeneration plant by waste heat utilisation with absorption heat pump
Authors: Zarzycki Robert , Panowski Marcin
Published: September 2019

The very rapid growth of share of electricity generation from renewable
sources is observed recent years. However, even if that share reaches about
50% in 2050, almost 50% of electricity will still be generated based on
fossil fuels combustion rather than on nuclear energy. That means, energy
generated from coal will still be important for the next decades. The
largest sources of energy loses within the steam power plant is the steam
cooling system. The energy dissipated to the atmosphere in that system is
very difficult to be utilized mainly due to the relatively low temperature,
and its direct utilization without additional equipment is rather
impossible. The large amount of energy lost to the environment leads to low
overall thermal efficiency of the plant, therefore, utilization of this
energy should be of primary importance. The paper shows concept of
increasing efficiency of cogeneration plant thermal cycle by utilisation of
waste heat from flue gas with absorption heat pump, for the purpose of
system heat generation. Calculations of combined system of power plant
fuelled with biomass fuel with implemented waste heat utilisation system
were performed for one heating season and different moisture content in the
fuel. Results show, that owing to waste heat utilization instead of
conventional heat exchanger, additional electricity generation during the
heating season at even 46864 MWh may be achieved which is over 18% more for
the moisture content in the biomass fuel at 0.5 kg/kg, the same ambient
conditions and heat generation.
An improved algebraic model for by-pass transition for calculation of transitional flow in pipe and parallel-plate channels
Authors: Nering Konrad , Rup Kazimierz
Published: September 2019

Modified algebraic intermittency model developed by E. Dick and S. Kubacki
was used to describe laminar-turbulent transition. In this work a
modification of this model was made for simulating internal flows in pipes
and parallel-plate channel. In particular, constants present in this model
were modified. These modified constants are the same for different flows in
pipes and parallel-plate channels. In this work, a dependence of friction
factor on Reynolds number and turbulence intensity were determined as well
as the localization of laminar breakdown and fully developed flow. Obtained
results were compared with theoretical and experimental data presented in
the literature.
Using adsorption chillers for utilising waste heat from power plants
Authors: Sztekler Karol , Kalawa Wojciech , Stefanski Sebastian , Krzywanski Jaroslaw , Grabowska Karolina , Sosnowski Marcin , Nowak Wojciech , Makowski Marcin
Published: September 2019

At present, energy efficiency is a very important issue and it is power
generation facilities, among others, that have to confront this challenge.
The simultaneous production of electricity, heat and cooling, the so-called
trigeneration, allows for substantial savings in the chemical energy of
fuels. More efficient use of the primary energy contained in fuels
translates into tangible earnings for power plants while reductions in the
amounts of fuel burned, and of non-renewable resources in particular,
certainly have a favorable impact on the natural environment. The main aim
of the paper was to investigate the contribution of the use of adsorption
chillers to improve the energy efficiency of a conventional power plant
through the utilization of combined heat and power waste heat, involving the
use of adsorption chillers. An adsorption chiller is an item of industrial
equipment that is driven by low grade heat and intended to produce chilled
water and desalinated water. Nowadays, adsorption chillers exhibit a low
coefficient of performance. This type of plant is designed to increase the
efficiency of the primary energy use. This objective as well as the
conservation of non-renewable energy resources is becoming an increasingly
important aspect of the operation of power generation facilities. As part of
their project, the authors have modelled the cycle of a conventional heat
power plant integrated with an adsorption chiller-based plant. Multi-variant
simulation calculations were performed using IPSEpro simulation software.
Experimental determination of the heat transfer coefficient in internally rifled tubes
Authors: Gradziel Slawomir , Majewski Karol , Majdak Marek
Published: September 2019

Development of the heat transfer surfaces on the tube inside makes it very
difficult or even impossible to determine the heat transfer coefficient
analytically. This paper presents the experimental determination of the
coefficient in an internally rifled tube with spiral ribs. The tests are
carried out on a laboratory stand constructed at the Institute of Thermal
Power Engineering of the Cracow University of Technology. The tube under
analysis has found application in a supercritical circulating fluidized bed
boiler. The heat transfer coefficient local values are determined for the
Reynolds numbers included in the range of ~6000 to ~50000 and for three
ranges of the heating elements power. As the medium flows through internally
rifled tubes with spiral ribs, the heat transfer process gets intensified
compared to similar processes taking place in smooth tubes. Based on the
obtained experimental data, a correlation is developed enabling
determination of the dimensionless Chilton-Colburn j factor. The equation
form is selected so that a comparison with existing results of tests
performed on rifled tubes can be made. Comparing the Nusselt number values
calculated based on the developed correlation with those obtained using
other correlations described in the literature, it can be observed that the
criterial number is about twice higher. The research results confirm the
thesis that the element internal geometry has a sub-stantial impact on the
heat transfer process.
Thermodynamic analysis of high temperature nuclear reactor coupled with advanced gas turbine combined cycle
Authors: Jaszczur Marek , Dudek Michal , Kolenda Zygmunt
Published: September 2019

One of the most advanced and most effective technology for electricity
generation nowadays based on a gas turbine combined cycle. This technology
uses natural gas, synthesis gas from the coal gasification or crude oil
processing products as the energy carriers but at the same time, gas turbine
combined cycle emits SO2, NOx, and CO2 to the environment. In this paper, a
thermodynamic analysis of environmentally friendly, high temperature gas
nuclear reactor system coupled with gas turbine combined cycle technology
has been investigated. The analysed system is one of the most advanced
concepts and allows us to produce electricity with the higher thermal
efficiency than could be offered by any currently existing nuclear power
plant technology. The results show that it is possible to achieve thermal
efficiency higher than 50% what is not only more than could be produced by
any modern nuclear plant but it is also more than could be offered by
traditional (coal or lignite) power plant.

Authors: Berkowicz Gabriela , Wrona Jan , Baron Jerzy , Bradlo Dariusz , Zukowski Witold
Published: September 2019

The process of oxidation of gaseous CH3OH by N2O was carried out over an
Ag-Fe2O3-cenosphere catalyst whose structure can be defined as double
shell-core catalyst. Preparation of the catalyst was carried out in two
stages: thermal decomposition of Fe(CO)5 at above 160?C and then
electroless Ag plating. The process of methanol degradation by N2O was
carried out in a fluidized bed reactor. The study confirms that it is
possible to achieve complete degradation of N2O and CH3OH for the obtained
catalyst at above 450?C when the contact time of the reactants with the
catalyst is approximately 6 second and when the substrates are used in
stoichiometric ratios. More than 60% of the hydrogen contained in CH3OH can
be converted to molecular hydrogen at 500?C with a ratio of N2O/CH3OH not
greater than 0.6 and with a contact time of reactants with the catalyst of
approx. 6 seconds.
An improved method for flow boiling heat transfer with account of the reduced pressure effect
Authors: Jakubowska Blanka , Mikielewicz Dariusz
Published: September 2019

In the paper are presented the results using the authors own model to predict
heat transfer coefficient during flow boiling. The model has been tested
against a large selection of experimental data to investigate the
sensitivity of the in-house developed model. In the work are presented the
results of calculations obtained using the semi-empirical model on selected
experimental flow boiling data of the refrigerants: R134a, R1234yf, R600a,
R290, NH3, CO2, R236fa, R245fa, R152a, and HFE7000. In the present study,
particular attention was focused on the influence of reduced pressure on
the predictions of the theoretical model. The main purpose of this paper is
to show the effect of the reduced pressure on the predictions of heat
transfer during flow boiling.
On-line monitoring of the fouling of the boiler heating surfaces
Authors: Trojan Marcin , Taler Dawid , Wielgus Szymon
Published: September 2019

The designed system for the monitoring of the fouling of the furnace and
super-heaters/reheaters, presented in the paper, will make it possible to
operate the boiler with high efficiency. Measurements of temperatures,
pressures, flows, and gas analysis data are used to perform heat transfer
analysis in the boiler furnace and evaporator. Power boiler efficiency is
calculated by an indirect method. The local and average degree of the
combustion chamber slagging is determined in an "on-line" mode. In the case
of superheaters, the fouling coefficient is determined for each superheater
stage, due to big differences in ash-related fouling of individual stages.
Fouling processes deteriorate the boiler capacity and efficiency and
increase the rate of corrosion of the boiler heating surfaces. The energy
consumption of flue gas fans rises as well because the accumulation of slag
and ash involves higher pressure losses at individual superheater stages.
In addition, examples of ash fouling of individual boiler heating surfaces
are presented and discussed in the paper.
Heat loss analysis of three coil cylindrical solar cavity receiver of parabolic dish for process heat
Authors: Sinha Ramola , Gulhane Nitin , Taler Jan , Oclon Pawel
Published: September 2019

The share of solar thermal energy for process heat at sub cooled temperature
is estimated about 30% of the total demand. The assessment of heat loss from
tubular receiver used for the process heat is necessary to improve the
thermal efficiency and consequently the cost effectiveness of the parabolic
dish receiver system. The study considers a modified three coil solar
cavity receiver of wall area three times (approximately) as compared to the
existing single coil receiver and experimentally investigates the effect of
increases in cavity inner wall area, fluid inlet temperature (50-75?C), and
cavity inclination angle (? = 0-90?) on the combined (total) heat loss from
receiver under no wind condition. This paper also develops an analytical
model to estimate the different mode of heat losses from the downward facing
receiver. In the mean fluid temperature range of 50?C to 70?C, the total
heat loss from three coil receiver is reduced up to 40.98% at 90? and 20% at
0? inclination, as compared to single coil receiver. The analytical modeling
estimates very low heat loss from conduction (1-3%) and radiation (2-8%)
and high heat loss from convection (97-89%). The heat loss by natural
convection decreases sharply with increase in cavity inclination, while the
heat loss by radiation and conduction increases slowly with inclination. A
three coil cavity receiver might be considered in the design to reduce heat
loss from parabolic dish receiver system to improve the thermal performance
and cost effectiveness.
Parametric study of non-evaporative spray cooling on aluminum plate: Simulation and analysis
Authors: Otmani Abdessalam , Mzad Hocine
Published: September 2019

As the behavior of the spray cooling parameters, during cooling without phase
change, is rarely considered and there are only little investigations on
that matter, this work is focused on the influence of the parameters
involved in water spraying cooling process of an aluminum plate at a
temperature of 92?C. A detailed study of the effects of mass-flow rate,
fluid pressure and the nozzle height above the hot plate was achieved using
the version 5.2 of the COMSOL Multiphysics code. First of all, the flow
rate was varied from 0.497 up to 1 L/min. Then, the inlet pressure varied
from 0.7 to 2.1 bars. The influence of nozzle-to-target distance is also
tested since the simulations were carried out in a wide height range (100 to
505 mm). The effect of the studied parameters on the temperature, total
internal energy, convective heat flux, Reynolds number, spray distribution
and velocity was investigated.
Understanding the Hemodynamics Involved in Ischemic Steal Syndrome of Arteriovenous Access
Authors: Hong Joon Ho
Published: September 2019

Highlights

This paper elucidates the significant role retrograde steal plays in the pathogenesis of ischemia by reviewing the successful outcomes achieved by widely employed surgical procedures. These successful interventions share an important hemodynamic feature to reverse distal ischemia: namely, the conversion of straight access configuration to a loop configuration. This conversion reduces retrograde steal, thereby increasing distal pressure and flow, resulting in the successful treatment of ischemic steal syndrome.

Long-term hemodialysis, the main treatment modality for patients with end-stage renal disease, requires reliable vascular access. The arteriovenous fistula is the preferred access but remains susceptible to complications, among which ischemic steal syndrome is the most serious. The pathophysiology of ischemic steal syndrome results from the diversion of arterial flow, antegrade, retrograde, or both, into the access.

Although antegrade diversion alone can cause steal syndrome, retrograde diversion plays a significant role in the development of ischemia, especially in patients with distal brachial artery-based access.

Recently, the role of retrograde steal was disputed, but this paper will elucidate the significant role of retrograde steal in the pathogenesis of ischemia by reviewing the successful outcomes achieved by widely employed surgical procedures. These successful interventions share an important hemodynamic feature to reverse distal ischemia: namely, the conversion of a straight access configuration to a loop configuration. This conversion reduces retrograde steal, thereby increasing distal pressure and flow, resulting in the successful treatment of ischemic steal syndrome.
Distal Ulnar Approach in the Palmar Artery for Coronary Angiography and Intervention: Safety, Feasibility, and Reliability in 15 Patients
Authors: Valsecchi Orazio , Vassileva Angelina , Cereda Alberto Francesco
Published: September 2019

Highlights

The distal ulnar palmar approach for both coronary angiography and intervention was safe, feasible, and reliable in our case series of 15 consecutive patients. The distal ulnar palmar approach was not a technical limitation for coronary angiography and interventional procedures in our cohort of patients. Further studies are needed to understand the potential benefits for patients and avoid medical futility.

Background: Transradial and translunar approaches, associated with fewer bleeding and vascular complications than transfemoral access, have been adopted and increasingly utilized following a “radial-first strategy.” Approaches that are innovative and more distal than standard radial approaches are available, even if their clinical utility is under debate. At the price of a more difficult puncture and risk of access failure, there are possible ergonomic advantages, with lower risk of upstream artery occlusion and shorter hemostasis.

Aim: The study was aimed at proving the preliminary feasibility, safety, and reliability of the right distal ulnar palmar approach in 15 consecutive patients.

Results: In 15 out of the 17 patients enrolled, the distal ulnar access in the palmar artery was feasible, safe, and reliable. The diameter of the distal ulnar artery was greater than that of the distal radial in the anatomical snuff box. There were no significant complications.

Conclusion: The distal ulnar palmar approach for both coronary angiography and intervention was safe, feasible, and reliable. It was not a limitation for coronary angiography and interventional procedures in our cohort of patients

ANALISIS HUKUM ISLAM TENTANG ZAKAT HASIL KORUPSI
Authors: Firdaweri Firdaweri
Published: September 2019

Abstrak: Ajaran Islam lengkap mengatur seluruh perbuatan manusia, termasuk memberi tuntunan tentang masalah harta yang wajib dizakatkan.  Masa kini masalah korupsi merupakan persoalan terhangat di Indonesia. Sebagian para pejabat berlomba-lomba melakukan korupsi.   Sehingga menimbulkan masalah jika dihubungkan dengan masalah zakat yang berfungsi membersihkan harta. Koruptor menzakatkan harta hasil korupsinya supaya menjadi bersih. Permasalahan ini harus dikaji hukumnya. Dalam hal ini penulis ingin memecahkan masalahnya dengan menentukan judul penelitian: “Analisis Hukum Islam Tentang Zakat Hasil Korupsi”, dengan rumusan masalah : 1. Bagaimana analisis hukum Islam tentang harta hasil korupsi?. Dan apakah termasuk harta yang wajib dizakatkan?. 2. Bagaimana harta hasil korupsi jika dizakatkan, apakah berobah menjadi suci?. Penelitian ini bertujuan mengetahui sejelas mungkin, dengan mempelajari dalil-dalil, sekaligus berusaha berfikir untuk menemukan ketentuan hukum Islam tentang zakat harta hasil korupsi. Penelitian ini termasuk penelitian hukum normative, yang bersifat deskriptif. Pengumpulan data library research,  dengan sistem analisa data kualitatif.  Berdasarkan data yang ada ditemukan bahwa:Harta korupsi termasuk harta yang haram, karena haram cara mendapatkannya. Harta yang haram tidak perlu dizakatkan, sebab harta yang termasuk kategori kewajiban membayar zakat adalah harta yang diperoleh dengan cara yang baik.   Harta yang wajib dibayar zakatnya adalah dimiliki secara sempurna. Koruptor bukan pemilik harta hasil dari korupsinya. Koruptor wajib mengembalikan  hasil korupsi kepada pemiliknya.Harta hasil korupsi jika dizakatkan tidak akan berobah menjadi suci, karena harta hasil korupsi adalah hasil penggelapan dan gratifikasi, termasuk kedalam harta yang haram seutuhnya. Jika dizakatkan tidak akan berobah menjadi suci.Jika koruptor benar-benar bertaubat, mempunyai niat yang kuat (ber-azam) tidak akan memakan harta yang telah dikorupsinya, untuk mengembalikan kepemilik harta tersebut, negara atau pemberi suap, Koruptor takut masuk penjara, menimbulkan kemudharatan yang lebih besar bagi dirinya,   Dalam hal ini peneliti berpendapat dengan metode sad al-dzariáh harta tersebut boleh diberikan untuk kepentingan umum, bukan untuk pribadi. Karena harta negara adalah untuk kepentingan masyarakat. Pihak penerima tidak berdosa. Dan hal ini bukan dinamakan sedekah atau zakat, tapi wujud dari rasa tobatnyaPara koruptor agar berhenti melakukan korupsi, harta hasil korupsi harus dikembalikan kepada pemiliknya. Korupsi itu perbuatan haram. Dan kepada KPK dan para pejabat yang berwenang agar meningkatkan pemberantas korupsi.Kata Kunci : Hukum Islam, Zakat, Korupsi.
