Portable Telematic System as an Effective Traffic Flow Management in Workzones
Authors: Ščerba Marek , Apeltauer Tomáš , Apeltauer Jiří 
Published: May 2015

Abstract
Traffic infrastructure localities with temporal restrictions for example due to reconstructions, or modernization, are important aspects influencing the traffic safety and traffic flow. On the basis of our research, we can identify main factors, which generate travel time loses, and which often cause traffic accidents in bottlenecks. First of all, it is improper late merge, speeding, tailgating, lower tolerance and consideration to other road users. Nervousness and ignorance of drivers also play an important role in generation of traffic congestions, lower level of service and resulting external economic loses. One of the tools eliminating the traffic restriction negative impacts is usage of portable telematics systems. In 2011 to 2013,project ViaZONE was in progress, which was to design an intelligent system with the aim to eliminate the mentioned risks and reduce economic losses generated by traffic congestions. Using available data and information, we have proved profitability and cost-effectiveness of dynamic systems for traffic control of work zones. Regarding traffic management, the system showed some problems due to indisciplined drivers and the system proved that speeding in these hazardous road segments is a common practice which caused accidents and congestions.

Summary
Anti-tumor necrosis factor (TNF)-α therapy is established as a new standard for the treatment of various autoimmune inflammatory diseases. We report the first case showing subacute thyroiditis-like symptoms with an amyloid goiter after anti-TNF-α therapy. A 56-year-old man with Crohn's disease presented with fever and a diffuse, tender goiter. To control the diarrhea, anti-TNF therapy (infliximab) was administered 4 weeks before the thyroid symptoms emerged. The patient reported a swollen neck with tenderness on the right side and fever 4 days after the second infliximab injection. An elevated serum C-reactive protein (CRP) and serum thyroid hormone level with suppressed serum thyrotropin were observed. The thyroid-stimulating antibody was not elevated. An ultrasonograph of the thyroid revealed an enlarged goiter with posterior echogenicity attenuation and a low echoic region that was tender. The thyroid uptake value on technetium-99m scintigraphy was near the lower limit of the normal range. The patient was initially diagnosed with thyrotoxicosis resulting from subacute thyroiditis. Administration of oral prednisolone improved the fever, thyroid pain, and thyroid function, but his thyroid remained swollen. The patient developed diarrhea after prednisolone withdrawal; therefore, adalimumab, another TNF inhibitor, was administered. After three injections, his abdominal symptoms were alleviated, but the thyroid pain and fever recurred. Elevated serum CRP levels in the absence of thyroid dysfunction were observed. The patient's symptoms resolved after prednisolone retreatment, but an elastic, firm goiter persisted. A fine-needle biopsy revealed amyloid deposition in the thyroid.

Learning points

Many cases with thyroid dysfunction accompanied by amyloid goiter have been reported.

There are cases that develop amyloid goiter with subacute thyroiditis-like symptoms after anti-TNF therapy.

When the thyroid remains swollen after improvement of thyrotoxicosis following treatment with prednisolone, it should be assessed to differentiate between an amyloid goiter and common subacute thyroiditis.

ObjectiveDue to the increasing success and survival rates in the primary treatment of malignancies derived from the CNS as well as the hematopoietic system, endocrine late effects of cancer and its therapy are of growing importance. Despite evaluation of these late effects in patients treated for cancer in childhood, the impact on adults remains largely unclear.Methods1035 adult patients primarily diagnosed with a CNS malignancy, a Hodgkin (HL) or non-Hodgkin lymphoma (NHL) between 1998 and 2008 were recruited via the regional epidemiological cancer registry covering ∼2.8 million inhabitants in the federal state of Schleswig-Holstein, Northern Germany. The prevalence of endocrine disorders and current psychosocial impairment was assessed employing several questionnaires (SF-36v1, WHO-5).ResultsFully completed questionnaires of 558 patients were available for subsequent analysis showing markedly reduced overall performance and psychological status when compared to German reference data. Thyroid disorders were reported in 16.3% of patients with 10.4% suffering from hypo- and 5.9% from hyperthyroidism. Overall, 17.6% stated to be affected by diabetes mellitus with an increased rate of 21.1% among NHL patients and 11.5% of participants were affected by osteoporosis.ConclusionCompared to German population based studies on the prevalence of diabetes mellitus, osteoporosis and thyroid disorders the frequency of all these endocrine problems was significantly increased in CNS, HL, and NHL cancer survivors. These data confirm that not only children and adolescents but also adult cancer patients are at risk for therapy associated endocrine late effects.
Erozyjny wpływ kosztów funduszy inwestycyjnych na wartość kapitału inwestorów w Polsce na tle wybranych krajów europejskich
Authors: Oleksy Paweł 
Published: May 2015

One factor that has a critical impact on mutual fund investors' terminal wealth is the fees which investors incur directly or indirectly in connection with establishing and maintaining their investment. Applying the Sharpe's Terminal Wealth Ratio Analysis, this study shows that cost burdens imposed by mutual funds operating in Poland greatly exceed the cost burdens of comparable investments made in more developed European countries, magnifying the erosive effect on investors' terminal wealth value, especially as the investment horizon is extended. For example, over a forty-year investment period the reduction in investment performance (investors' terminal wealth value) attributed only to the disparity of mutual fund fees in Poland compared with the other European countries, on average, are as follows: about 35% in money market funds, 42% for fixed-income funds, 197% in the case of equity funds, and 234% in the case of allocation funds. This fact demonstrates both the immaturity of the Polish mutual fund market and a lack of economic knowledge and experience among domiciled investors. This, coupled with the absence of sufficient involvement of public institutions to create a cheap, efficient and safe allocation mechanism for investors' savings, contributes to a much deeper erosion of their wealth than in developed countries.

Abstract

Background.
Due to its rarity, male breast cancer (mBC) remains an inadequately characterized disease, and current evidence for treatment derives from female breast cancer (FBC).

Methods.
We retrospectively analyzed the clinicopathological characteristics, treatment patterns, and outcomes of mBCs treated from 2000 to 2013.

Results.
From a total of 97 patients with mBC, 6 (6.2%) with ductal in situ carcinoma were excluded, and 91 patients with invasive carcinoma were analyzed. Median age was 65 years (range: 25–87 years). Estrogen receptors were positive in 88 patients (96.7%), and progesterone receptors were positive in 84 patients (92.3%). HER-2 was overexpressed in 13 of 85 patients (16%). Median follow-up was 51.5 months (range: 0.5–219.3 months). Five-year progression-free survival (PFS) was 50%, whereas overall survival (OS) was 68.1%. Patients with grades 1 and 2 presented 5-year PFS of 71% versus 22.5% for patients with grade 3 disease; 5-year OS was 85.7% for patients with grades 1 and 2 versus 53.3% of patients with grade 3. Ki-67 score &gt;20% and adjuvant chemotherapy were also statistically significant for OS on univariate analyses. Twenty-six of 87 patients (29.8%) experienced recurrent disease and 16 of 91 patients (17.6%) developed a second neoplasia.

Conclusion.
Male breast cancer shows different biological patterns compared with FBC, with higher positive hormone-receptor status and lower HER-2 overexpression. Grade 3 and Ki-67 &gt;20% were associated with shorter OS.

Implications for Practice:
There is little evidence that prognostic features established in female breast cancer, such as grading and Ki-67 labeling index, could be applied to male breast cancer as well. This study found that grade 3 was associated with shorter overall survival and a trend for Ki-67 &gt;20%; this could help in choosing the best treatment option in the adjuvant setting. Many questions remain regarding the impact of HER-2 positivity on survival and treatment with adjuvant anti-HER-2 therapy. Regarding metastatic male breast cancer, the results suggest that common regimens of chemo-, endocrine and immunotherapy used in female breast cancer are safe and effective for men. Male breast cancer patients show a higher incidence of second primary tumors, especially prostate and colon cancers and should therefore be carefully monitored.
Managing for the Moment: The Role of Earnings Management via Real Activities versus Accruals in SEO Valuation
Authors: Kothari S. P. , Mizik Natalie , Roychowdhury Sugata 
Published: May 2015

ABSTRACT
We assess the role of both accruals manipulation (AM) and real activities manipulation (RAM) in inducing overvaluation at the time of a seasoned equity offering (SEO). Our results reveal that earnings management is most consistently and predictably linked with post-SEO stock market underperformance when it is driven by RAM; in particular, the opportunistic reduction of expenditures on R&D and selling, general, and administrative activities. Thus, overvaluation at the time of the SEO is more likely when managers actively engage in more opaque channels to overstate earnings. Our findings are particularly relevant because managers exhibit a greater propensity for RAM at the time of SEOs, even though RAM is more costly in the long run.

Ovules, Female Gametophytes and Embryos are More Sensitive to Heavy Metal Pollution than Anthers and Pollen of Cardaminopsis Arenosa (L.) Hayek (Brassicaceae), A Member of Calamine Flora
Authors: Monika Kwiatkowska , Romana Izmaiłow 
Published: May 2015

Abstract
Reproductive processes including male and female lines, embryo and endosperm development were studied in Cardaminopsis arenosa (syn. Arabidopsis arenosa) growing on two metalliferous sites (Bukowno and Bolesław, S. Poland), rich in Zn, Pb, Cd and other metals. Disturbances of developmental processes and necroses observed in anthers and ovules influenced plant fertility and seed set of plants from both metal-polluted sites. In anthers, disturbances and necrosis during male meiosis and pollen development occurred at low frequency (4-5%). Pollen grain viability was very high, reaching over 90%. In ovules the frequency of abnormal meiosis, female gametophyte developmental disturbances and necrosis was high, 23.5-28% depending on site. The polluted environment also affected embryo and endosperm. Necrosis of whole generative structures decreased plant fertility. This study indicates that the range of disturbances and necroses in embryological structures and processes (at gametophyte level) gives a set of useful characters to determine plant tolerance to stress, complementary to many tolerance characters at the sporophyte level of plant ontogenesis.

Published: May 2015

ABSTRACT
The tests results of superduplex stainless steel welded joints made with a different heat input, using automatic submerged arc welding (SAW) and semi-automatic flux-cored arc welding (FCAW) have been presented. Metallographic examinations, the measurements of the ferrite content, the width of the heat affected zone (HAZ) and the hardness of the welds in characteristic areas have been performed. Significant differences in the amount of ferrite in the weld metal and in the heat affected zone microstructure of joints were found.

Published: May 2015

Abstract
The goal of the research was to evaluate the change of displacement/strain phases in the P91 steel under static load conditions. Undertaken tests were aimed at estimation and analysis of the impact of the material state, which was subjected to loading conditions, on the distribution of stress pattern using ESPI system. Specimen made of high temperature creep resistant steel X10CrMoVNb9-1 (P91) used as a construction material for boiler steam feed heaters, vapor tanks, pressure vessels and vapor pipelines, is used in the service conditions of temperature range up of 650°C. Test samples were taken from two P91 steel pipes. One sample came from a segment of a pipeline transporting fresh vapor in time 80 000 h, under the pressure of 8.4 MPa and temperature 540 °C. The second sample was the same material but in the delivery state.

Published: May 2015

Abstract
This study examined effect of inclusion of expanded graphite (Exp-G) on morphology, thermal, mechanical and flame retardant properties of PS, nitro-substituted polystyrene (N-PS) and amino-functional polystyrene (A-PS). FESEM showed exfoliated sheet morphology due to intercalation of N-PS and A-PS in expanded galleries. Tensile strength of A-PS materials (31.5-56.9 MPa) was higher than PS and N-PS. 10 % weight loss of A-PS nanocomposites (482-518 °C) was higher relative to pristine polymer and other nanocomposites. Cone calorimetry results revealed that there was lowering in PHHR of A-PS nanocomposites with 0.5 wt.% filler (428 kW/m2), while PS nanocomposites showed PHHR of 443 kW/m2.
Validation of the X-Ray Stress Measurement Method
Authors: Szymański W. , Lech-Grega M. 
Published: May 2015

Abstract
One of the most important characteristics of the material allowing us to predict its applicability for specific tasks as a single object or as an integral part of the whole structure is the presence of stresses. There are many methods to measure stress. Among them, increasingly important and recognised as the most accurate non-destructive method is the X-ray measurement technique. The aim of this study was validation of the results obtained by the X-ray stress measurement method. Stress measurements were performed on samples of the three materials subjected during measurement to the effect of tensile forces. Studies revealed close relationship between the stress values measured by X-ray technique and actual values present in the examined material. The summation of residual stresses present in the material and stresses caused by the effect of external forces was observed.
Amplifier Noise Based Optical Steganography with Coherent Detection
Authors: Wu Ben , Chang Matthew P. , Caldwell Naomi R. , Caldwell Myles E. , Prucnal Paul R. 
Published: May 2015

AbstractWe summarize the principle and experimental setup of optical steganography based on amplified spontaneous emission (ASE) noise. Using ASE noise as the signal carrier, optical steganography effectively hides a stealth channel in both the time domain and the frequency domain. Coherent detection is used at the receiver of the stealth channel. Because ASE noise has short coherence length and random phase, it only interferes with itself within a very short range. Coherent detection requires the stealth transmitter and stealth receiver to precisely match the optical delay,which generates a large key space for the stealth channel. Several methods to further improve optical steganography, signal to noise ratio, compatibility with the public channel, and applications of the stealth channel are also summarized in this review paper.

IDEAS in AGORA: The Philosophy of the Empires, Fear and Sense of Exemplarity
Authors: Maximiliano Korstanje 
Published: May 2015

Abstract
Why do the United States reserve the right to be called “America” by conferring the “Americas” to the whole continent?, is that a clear sign of discrimination or supremacy or both? Ideologically, America refers to the United States of “America” excluding other regions such as Latin America, central or South America. This leads some scholars to explain convincingly that, beyond this subtle grammatical difference, the Anglo-ethnocentrism in the United States has been drawn to make their citizens believe they are unique, outstanding, and special. Basically, this belief allowed not only to fight against the political enemies in Europe or in any other geographical point, but also to control the incipient worker union leaderships. What merits further attention, anyway, is the sentiment of exemplarity instilled by the founding parents of this nation. Fear was historically a mechanism of control employed by US governments at different stages in several ways. Our intention is not only to review how the fear disciplined by the claims of work-force, but also explain why the sentiment of exemplarity and fear are inextricably intertwined.
SIGNS and MEANINGS: Translation in the Middle Ages versus Translation today: The Semiotics of Translation
Authors: Guillaume Astrid 
Published: May 2015

Abstract
Translation in the Middle Ages did not involve the same constraints as translation today for various reasons, which this article will attempt to highlight through a semiotic analysis of the opposing powers and other translation-related pressures which interact in the translation process. This process involves a source language and a target language, but above all a source culture and target culture. Translation in the Middle Ages, like translation today, is primarily about taking into consideration certain constraints, some of which are shared between the two eras but which, in all cases, take into account the period in which they were translated. Indeed, an era involves modes of thought, political and religious ideologies, translation and stylistic practices that are unique to that particular time. If, as example periods, we have chosen two eras which are quite remote from each other, it is to demonstrate that the issues certainly differ, but not as much as one might imagine, particularly in certain political and ideological contexts.
“Ethics” of Interval
Authors: Bejan Petru 
Published: May 2015

Abstract
In the Christian imaginary, the ternary representation of the universe is reiterated by appealing either to the Platonic texts, or to the Stoic ones. The triadic scheme of the worlds certifies an ambiguous status of man, of an individual placed neither here nor there, by the force of some circumstances which he cannot resist. Situated at equal distance from sidereal heights - credited as having the monopoly on perfection - and from the terrifying shadows, managed in a totalitarian manner by the instances of evil, in “the world between the worlds”, he thinks of the interval as of a space of communication, filled with signs, shapes and characters, by means of which distances can be “neared, compressed and “humanised”. Each step, stage, climb or descent is perceived as a “rupture of level”, as overcoming of the human condition by assuming a trans-mundane axiological repertoire
An Exercise in a Transdisciplinary Approach for New Knowledge Paradigms
Authors: Crumpei Gabriel , Agop Maricel , Gavriluţ Alina , Crumpei Irina 
Published: May 2015

Abstract
In this paper, we aim at an exercise that is transdisciplinary, involving science and religion, and interdisciplinary, involving disciplines and theories which appeared in the second half of the 20th century (e.g., topology, chaos theory, fractal geometry, non-linear dynamics, all of which can be found in the theory of complex systems). The latter required the reformulation of quantum mechanics theories starting with the beginning of the century, based on the substance-energy-information triangle. We focus on information and we also attempt a transdisciplinary approach to the imaginary from a psychological - physical - mathematical perspective, but the religious perspectives find their place along with the philosophical or even philological vision
