Optikai iparban termelődő szürkevíz minőségi és mennyiségi vizsgálata, javaslattétel kezelési technológiára
Authors: Ungvári Levente , Keczánné Üveges Andrea
Published: April 2017

Kutatásunk során a Carl Zeiss Vision Hungary Kft. mosodai szürkevizét vizsgáltuk. Kutatásunk célja, hogy az optikai iparban termelődő szürkevíz minőségi és mennyiségi paramétereiről átfogó képet kapjunk. A minőségi paraméterekre nézve további célunk volt, hogy vizsgáljuk, szükségszerű-e elszeparáltan gyűjteni az optikai iparban termelődő különböző eredetű szürkevizet. Ezt követően pedig olyan kezelési technológia kidolgozását terveztük, amely szürkevíz kezelés szempontjából gazdaságilag is értékes lenne a cég számára. Vizsgálatai eredményeink alátámasztják, hogy nem szükségszerű elszeparáltan gyűjteni a mosógépekből illetve a takarítógépekből származó szürkevizet, hiszen azok hasonló mértékben terheltek szennyező anyagokkal. A szürkevíz tisztítási technológiák pénzügyi értékeléséhez két különböző elven működő technológiát vettünk alapul (koaguláció-flokkuláció, és aerob biomembrán technológia). Beruházási és fenntartási költségek tekintetében is egyértelműen az aerob biomembrán technológia megvalósítása bizonyult gazdaságosabbnak.

Published: April 2017

Экспериментально исследовалась динамика длинноволнового края спектра собственного стимулированного пикосекундного излучения, возникающего во время пикосекундной накачки GaAs. Обнаружен дефицит перенормировки запрещенной зоны, вызванной кулоновским взаимодействием носителей заряда, по сравнению с перенормировкой в квазистационарном состоянии. Предполагается, что дефицит обусловлен тем, что в условиях настоящего эксперимента время релаксации перенормировки относится к пикосекундному диапазону. DOI: 10.21883/FTP.2017.05.44412.8353

Влияние интеркалированного водорода на электронное состояние квазисвободного графена на подложке SiC
Authors: Давыдов С.Ю.
Published: April 2017

Для оценки роли интеркалированного водорода в допировании квазисвободного эпитаксиального графена рассмотрены две системы: (i) графен-NH-SiC\0001\ и (ii) графен-монослой водорода-NH-SiC\0001\, где N=4, 6. В случае (i) смещение точки Дирака эпитаксиального графена вызывается электростатическим полем спонтанной поляризации подложки, в случае (ii) --- полем двойного электрического слоя, возникающего вследствие адсорбции атомов водорода. Показано, что во втором случае по сравнению с первым концентрация дырок в графене увеличивается, а концентрация электронов уменьшается, что соответствует имеющимся экспериментальным данным.

Исследование процесса спада напряжения при ударно-ионизационном переключении силовых тиристоров
Authors: Гусев А.И. , Любутин С.К. , Рукин С.Н. , Цыранов С.Н.
Published: April 2017

Исследован процесс спада напряжения на силовых тиристорах, переключаемых в проводящее состояние волной ударной ионизации, возбуждаемой подачей на основные электроды тиристора импульса перенапряжения с наносекундным фронтом. В экспериментах на тиристор с рабочим напряжением 2 кВ подавалось напряжение со скоростью нарастания dU/dt в диапазоне 0.5-6 кВ/нс. Численное моделирование показало, что расчетные и экспериментально наблюдаемые времена спада напряжения имеют количественное согласие только в том случае, когда величина активной площади структуры, через которую проходит ток переключения, зависит от dU/dt. Активная площадь увеличивается с возрастанием dU/dt, а также с увеличением удельного сопротивления исходного кремния. При этом активная площадь монотонно приближается к полной площади структуры при dU/dt>12 кВ/нс. DOI: 10.21883/FTP.2017.05.44429.8367

Published: April 2017

Методом межатомных потенциалов проведено моделирование ромбического сегнетоэлектрика-сегнетоэластика (beta'-фазы) молибдата гадолиния Gd2(MoO4)3. Для моделирования использовалась программа GULP 4.0.1 (General Utility Lattice Program), в основу которой положена процедура минимизации энергии кристаллической структуры. Параметры потенциалов межатомного взаимодействия гадолиний-кислород определены подгонкой к экспериментальным структурным данным и упругим константам в рамках процедуры, предусмотренной в программе GULP. Атомистическое моделирование с использованием эффективных зарядов атомов и полученной системы межатомных потенциалов позволило сделать разумные оценки структурных параметров и координат атомов, важнейших физических, механических и термодинамических свойств этих кристаллов. Получены температурные зависимости теплоемкости кристалла и колебательной энтропии. Рассчитанные значения параметров потенциалов взаимодействия гадолиний-кислород могут быть использованы для моделирования более сложных гадолиний-содержащих соединений.

Theoretical study on pegylation reaction mechanisms of IFN-α-2a, IFN-α-2b and IFN-β-1a
Authors: Taqavian Mohammad , Abedi Daryoush , Zigheimat Fatemeh , Zeidabadinejad Leila
Published: April 2017

Ab initio and DFT calculations have been carried out to study the reaction mechanism between interferons (IFNs) ?-2a, ?-2b and ?-1a and polyethylene glycol (PEG) group. The calculations show that the mechanisms are concerted, in agreement with the results of experimental works. However, although it appears that there is one single transition state, the characteristics of its structure reveal a very synchronous reaction mechanism. The reactions are clearly exothermic and as well have feasible activation energies. Our computational study shows that the lowest transition state energies are related to Lys 134, His 34 and Met 1 of IFN-?-2a, IFN-?-2b and IFN-?-1a, respectively.

Published: April 2017

Introduction/Objective. Hand functions have an enormous impact on activities of daily living in patients with diabetes mellitus (DM), such as self-care, administering insulin injections, and preparing and eating meals. The aim of the study was to evaluate hand functions and grip strength in patients with type 1 and type 2 DM. Methods. This was an observational case-control study investigating the hand functions and grip strength in patients with type 1 and type 2 DM. The study comprised 41 patients with type 1 DM aged 25?50 years sex- and age-matched, 40 non-diabetic controls, and 91 patients with type 2 DM aged 40?65 years sex- and age-matched 60 non-diabetic controls. Patients with documented history of diabetic sensorimotor neuropathy and adhesive capsulitis were excluded. The Duruoz Hand Index was used to assess the functional hand disability. Grip strength was tested with a calibrated Jamar dynamometer. Results. The Duruoz Hand Index scores in patients with type 2 DM were significantly higher than in persons in the control group (p < 0.01), but there was no significant difference between the type 1 DM and the control group (p > 0.05). Grip strength values of patients with type 1 DM were significantly lower compared to those in the control group (p < 0.05), whereas there was no significant difference between patients with type 2 DM and their control group. There was a negatively significant correlation between grip strength and the Duruoz Hand Index scores in patients with both type 1 and type 2 DM (p < 0.05). Conclusion. Patients with type 1 DM and type 2 DM have different degrees of hand disability as compared to healthy control groups.
Road to organ preservation in locally advanced rectal cancer
Authors: Nestorovic Milica , Stanojevic Goran , Brankovic Branko
Published: April 2017

Introduction. In the past 20 years there has been significant change in the treatment of rectal cancer, especially in terms of multimodal approach. Surgery is, at least for now, the mainstay treatment for resectable rectal cancer. Preoperative chemoradiotherapy is, regardless of its modality, short or long course, different chemotherapeutic regiments, widely recommended for locally advanced rectal cancer. After neoadjuvant treatment, 15?27% of patients experience pathological complete response (pCR). These patients could benefit from non-operative management, thus avoiding potential surgical complications and possible reduction in the quality of life. Unfortunately, one cannot precisely define, while omitting surgery, which patients have pCR. For this reason Habr-Gama, a pioneer in the ?watch-and-wait? strategy, developed a new endpoint for non-operative management ? clinical complete response. To measure the response, in the absence of pathological examination, same diagnostic tools are used as in initial staging, but none is reliable enough to be used alone. This article is focusing on critical points in the reassessment of response to preoperative chemoradiotherapy for advanced rectal cancer, which is mandatory for appropriate selection of patients who might benefit from non-operative management.

Published: April 2017

Introduction. Direct malignant invasion by primary lung tumors or by nodular metastases is the most frequent indication for superior vena cava resection and reconstruction. The aim of our work is to underline the importance of good evaluation and preoperative workup from the standpoint of the overall survival. Case outline. A male patient, aged 61 years, was admitted for the surgical treatment of adenocarcinoma of the right lung upper lobe. The proposed protocol for the treatment of our patient comprised radiological verification, biopsy with histopathology analysis, standard upper lobectomy with mediastinal lymphadenectomy and with resection of the superior vena cava in a length of about 30 mm. Reconstruction of the superior vena cava was done by implanting a 16 mm INTERGARD vascular graft, using the running suture. In our patient, grafting and bridging the superior vena cava structure prevented the development of postoperative vascular complications and improved survival from the beginning of the treatment. Conclusion. Mixed thoracic and vascular surgical treatment reduces postoperative complications and improves survival.

for the artificial intelligence to have understanding of a language in a way
in which intelligent beings such as humans have that capacity. The argument
was influential enough to, in decades following it, sparke numerous responses
and critiques, along with a few alleged improvements to it from Searle. In
this article, I will analyze one atypical critique of Searle?s argument, made
by Mark Sprevak. Sprevak, unlike the other critics of the argument, agrees
with Searle that understanding does not exist in Chinese room in any way, but
he claims that Chinese room cannot execute every possible program, like
Searle claims. Because of that, Searle cannot conclude the strong conclusion
he wants from The Chinese room argument. In this article, I will analyze
Searle?s argument, I will give a brief overview of typical responses to it,
and I will analyze Sprevak?s response. In the last section, I will present
argument that shows that Sprevak, if he wants to keep his conclusions, must
either give up one part of his response, or accept one of the typical
responses to Searle?s argument, thus making his own response dependent on the
response from others.
Access granted to Zombies
Authors: Prelevic Dusko
Published: April 2017

In his ?Access Denied to Zombies?, Gualtiero Piccinini argues that the
possibility of zombies does not entail the falsity of physicalism, since the
accessibility relation can be understood so that even in S5 system for modal
logic worlds inaccessible from our world are allowed (in the case in which
the accessibility relation is understood as an equivalence rather than as
universal accessibility). According to Piccinini, whether the zombie world is
accessible from our world depends on whether physicalism is true in our
world, which is something that cannot be answered in a non-question-begging
way. In order to show this, he recalls a well known strategy of making a
parody of the zombie argument. After pointing out that Piccinini?s strategy
of parodying the zombie argument renders his former strategy, based on the
distinguishing between the two notions of accessibility, redundant, I recall
the two ways of handling parodies of the zombie argument. In addition, I
argue that persisting on the distinction between accessibility understood as
an equivalence and universal accessibility in dealing with the zombie
argument relies upon accepting modal dualism (a view that there are two
spaces of possibilities rather than one), which is something usually
dismissed for methodological reasons (simplicity in particular). Given that
Piccinini has not provided new arguments neither in favour of modal dualism
nor in favour of parodying the zombie argument, the conclusion he infers
remains unsupported by the premises he uses.
The notion of convention: Poincaré, Schlick, Reichenbach
Authors: Jovanovic Radmila
Published: April 2017

After the appearance of non-Euclidian geometries, Kant?s apriorism regarding
geometry was seriously put in question. Poencar? challenged both apriorism
and empricism, claiming that the question of ?true geometry? of our phisical
world has no meaning. His position became known as conventionalism. Logical
positivists recognised the importance of understanding the nature of
conventional elements in our scientific knowledge, especially after the
appearence of the general relativity theory, but their positions differe
concerning their role. While Schlick accepted the term ?conventions? when
speaking of basic elements of physics, young Rajhenbah called those elements
?relativistic a priori?, arguing that Kant?s doctrine can be accomodated even
to the new relativistic physics. After an important correspondence between
two philosophers, they astonishingly agreed that their dispute is purely
terminological. I want to analyse their postions and to argue that this
diagnosis was in fact mistaken.
Normativity of Nietzsche’s ethics
Authors: Agatonovic Milos
Published: April 2017

The task of this text is to locate Nietzsche?s ethics in the domain of
normativity. Namely, this task assumes the determination of the normative
concepts of Nietzsche?s ethics, the relations between them, and their
relations with non-normative concepts, but, before all, an answer to the
question about meaning of ethics in Nietzsche?s philosophy. In our
discussion, for the sake of methodicity and accuracy, we are going to use the
concepts and the conceptual distinctions of the philosophy of normativity, a
contemporary discipline of ethics. The result of the discussion will be the
proof of two theses: (i) Nietzsche?s ethics refers to a normative judgment
about reasons to act; and (ii) according to it, normative or ethical concepts
supervene on non-normative and non-ethical concepts.
Prions and animal transmissible spongiform encephalopathies
Authors: Juntes Polona , Zabavnik-Piano Jelka , Ivan Ambrozic
Published: April 2017

Background. Transmissible spongiform encephalopathies (TSEs) or prion
diseases are a unique group of neurodegenerative diseases of animals and
humans, which always have a fatal outcome and are transmissible among animals
of the same or different species. Scope and Approach. The aim of this work is
to review some recent data about animal TSEs, with the emphasis on their
causative agents and zoonotic potential, and to discuss why the surveillance
and control measures over animal TSEs should remain in force. Key Findings
and Conclusions. We still have incomplete knowledge of prions and prion
diseases. Scrapie has been present for a very long time and controlled with
varied success. Bovine spongiform encephalopathy (BSE) emerged unnoticed, and
spread within a few years to epidemic proportions, entailing enormous
economic consequences and public concerns. Currently, the classical BSE
epidemic is under control, but atypical cases do, and probably will, persist
in bovine populations. The Chronic Wasting Disease (CWD) of the cervids has
been spreading in North America and has recently been detected in Europe.
Preventive measures for the control of classical BSE remain in force,
including the feed ban and removal of specified risk materials. However,
active BSE surveillance has considerably decreased. In the absence of such
preventive and control measures, atypical BSE cases in healthy slaughtered
bovines might persist in the human food chain, and BSE prions might
resurface. Moreover, other prion strains might emerge and spread undetected
if the appropriate preventive and surveillance measures were to cease,
leaving behind inestimable consequences.
Immunomodulator, Mycobacterium cell wall fraction, an aid in control of persistent Mycoplasma bovis infection in dairy cows
Authors: Masic Aleksandar , Prunic Bojana , Bugarski Dejan , Petrovic Tamas , Barna Tomislav , Apic Jelena , Milovanovic Aleksandar
Published: April 2017

Mycoplasma bovis is pathogen known to cause respiratory disease, otitis
media, arthritis and a variety of additional diseases in cattle. Infections
caused by this pathogen have significant impact on the health, welfare and
productivity of dairy and beef cattle resulting in substantial economic
losses. Current preventive and treatment strategies rely on the use of
antimicrobials and vaccines; however, their efficacy is limited due to
difficult diagnosis and inconsistent disease expression. Here, we report
results on the use of Mycobacterium cell wall fraction (MCWF), an
immunomodulator, in dairy cows persistently infected with M. bovis during the
period 2011-2015. Application of MCWF aided in reducing M. bovis-associated
clinical signs, such as pneumonia, arthritis and mastitis, and improving
overall reproductive performance and days in lactation of infected dairy
cows. These results were compared to historical information on the health
status and farm performance for period 2011-2015, and suggest that MCWF
immunomodulator could be introduced as an aid in treatment protocols for
persistent infections with M. bovis in dairy cows.
Measuring Accounting Reporting Complexity with XBRL
Authors: Hoitash Rani , Hoitash Udi
Published: April 2017

We propose a new measure of accounting reporting complexity (ARC) based on the count of accounting items (XBRL tags) disclosed in 10-K filings. The preparation and disclosure of more accounting items is complicated because it requires greater knowledge of authoritative accounting standards. This aspect of complexity can increase the likelihood of mistakes, incorrect application of GAAP, and can ultimately lead to less credible financial reports. Consistently, we find that ARC is associated with a greater likelihood of misstatements and material weakness disclosures, longer audit delay, and higher audit fees. In comparison to commonly used measures of operating and linguistic complexity, the associations between ARC and these outcomes are more consistent, exhibit greater explanatory power, and have stronger economic significance. These and additional validation and robustness tests suggest that ARC more completely reflects accounting complexity. In addition, ARC exhibits several advantageous properties, including across- and within-firm variation, availability for the universe of SEC filers, and a direct connection to accounting, inherent in its derivation from detailed accounting disclosures. Finally, because it relies on a comprehensive set of detailed accounting data, ARC broadly captures accounting complexity, while, at the same time, it can be disaggregated into account-specific measures of complexity.

The Credibility of Financial Reporting: A Reputation-Based Approach
Authors: Liang Ying , Marinovic Iván , Varas Felipe
Published: April 2017

This paper studies the reliability of financial reporting when the credibility of the manager, represented by his misreporting propensity, is unknown. We show that credibility concerns affect the time-series of reported earnings, book values, and stock prices in ways that seem consistent with empirical evidence. When investors are uncertain about the credibility of the reporting process, earnings response coefficients, as well as market-to-book values (MTB), are random and time-varying; relatively low MTB reflect poor credibility of financial reporting; stock prices are s-shaped in earnings surprises and relatively insensitive to bad news. Finally, when the manager is more likely to have reporting discretion, discretionary accruals tend to be larger and more volatile. We estimate the model using U.S. earnings announcement data during 2002–2012 and find that the probability of misreporting is 7 percent. A counterfactual analysis reveals that ignoring the possibility of misreporting leads to overestimation of the mean (3.5 percent), volatility (13 percent), and persistence of earnings (17 percent).

Status Differences and Knowledge Transfer: The Effect of Incentives
Authors: Haesebrouck Katlijn , Cools Martine , Van den Abbeele Alexandra
Published: April 2017

We examine how incentive systems influence knowledge transfer between group members with equal or different status who solve an interdependent task. In our experiment, group members receive group or individual incentives, while status is manipulated by assigning job titles with corresponding role descriptions. Although all conditions require knowledge sharing to maximize payoffs, our results suggest that significantly more knowledge is shared under group incentives relative to individual incentives when status differences are present, whereas the amount of knowledge shared does not differ across these incentive manipulations for equal-status groups. These findings are in line with theory suggesting that individual incentives can motivate knowledge sharing among equal-status groups, but cannot overcome the negative interactions that arise under status differences. Instead, group incentives are required to induce cooperative behavior that mitigates the negative effects of status differences on knowledge sharing. We contribute to the literature and practice by showing that the effect of incentives depends on the social context and that job titles can have unintended consequences.
Can Paying “Too Much” or “Too Little” Tax Contribute to Forced CEO Turnover?
Authors: Chyz James A. , Gaertner Fabio B.
Published: April 2017

Our study examines the effect of corporate tax outcomes on forced CEO turnover. While prior research argues that firms often do not engage in tax avoidance due to reputational concerns, the empirical evidence suggesting the existence of reputational costs is scarce. In a broad sample of firms, we find evidence of a relation between the payment of low taxes and forced turnover. We also find that forced CEO turnover is more likely when the firm pays a high tax rate relative to its peers. Our results are consistent with the existence of previously unexplored individual reputational costs for not engaging in tax avoidance.

The Impact of Social Influence Pressures, Commitment, and Personality on Judgments by Auditors: Evidence from Japan
Authors: Tsunogaya Noriyuki , Sugahara Satoshi , Chand Parmod
Published: April 2017

We examine whether obedience and conformity pressures generated by superiors (partners) and colleagues within audit firms cause dysfunctional audit behavior in Japan. We also investigate whether high levels of professional and organizational commitment and the personal attributes of auditors mitigate these pressures. The results indicate that obedience pressure can impair the judgments of auditors, whereas conformity pressure does not have a significant influence. The application of a three-dimensional model of commitment and a five-dimensional scale of individual personalities reveals that dysfunctional audit behavior can be mitigated by enhancing affective and normative commitment, and by addressing highly masculine characteristics in individual auditors.
Efficacy of piezocision on accelerating orthodontic tooth movement: A systematic review
Authors: Yi Jianru , Xiao Jiani , Li Yu , Li Xiaobing , Zhao Zhihe
Published: April 2017

Objectives:

The aim of this systematic review was to evaluate the effect of piezocision as an adjunctive procedure to accelerate orthodontic tooth movement.

Materials and Methods:

Randomized controlled trials and controlled clinical trials that investigated the effectiveness of piezocision on accelerating orthodontic tooth movement were identified through electronic and manual searches. The literature search, study inclusion, risk of bias assessment, and data extraction were performed by two reviewers independently.

Results:

Four eligible studies were included in this review. All studies reported accelerated tooth movement after piezocision, and three reported a significant reduction of treatment duration in the piezocision group. No deleterious effects on periodontal status, pain perception, satisfaction, root resorption, or anchorage control were reported in any studies.

Conclusion:

Based on currently available information, weak evidence supports that piezocision is a safe adjunct to accelerate orthodontic tooth movement, at least in the short term. More high-quality clinical trials to determine the long-term effects and optimal protocol for piezocision are needed to draw more reliable conclusions.
Empagliflozin and Kinetics of Renal Glucose Transport in Healthy Individuals and Individuals With Type 2 Diabetes
Authors: Al-Jobori Hussein , Daniele Giuseppe , Cersosimo Eugenio , Triplitt Curtis , Mehta Rucha , Norton Luke , DeFronzo Ralph A. , Abdul-Ghani Muhammad
Published: April 2017

Renal glucose reabsorption was measured with the stepped hyperglycemic clamp in 15 subjects with type 2 diabetes mellitus (T2DM) and 15 without diabetes after 2 days and after more chronic (14 days) treatment with empagliflozin. Patients with T2DM had significantly greater maximal renal glucose transport (TmG) compared with subjects without diabetes at baseline (459 ± 53 vs. 337 ± 25 mg/min; P < 0.05). Empagliflozin treatment for 48 h reduced the TmG in both individuals with and without diabetes by 44 ± 7 and 53 ± 6%, respectively (both P < 0.001). TmG was further reduced by empagliflozin in both groups on day 14 (by 65 ± 5 and 75 ± 3%, respectively). Empagliflozin reduced the plasma glucose concentration threshold for glucose spillage in the urine similarly in individuals with T2DM and without diabetes to <40 mg/dL, which is well below the normal fasting plasma glucose concentration. In summary, sodium-glucose transporter-2 inhibition with empagliflozin reduces both TmG and threshold for glucose spillage in the urine in patients with T2DM and those without diabetes.
