Full textAbstract:
Background: Colorectal cancer (CRC) is fourth most frequent cancer in men and third most common cancer in women in Turkey according to GLOBOCAN 2012 data. Its age-standardized incidence is 16.6 per 100,000 population in both sexes. CRC screening is globally accepted program and was shown that reduces CRC mortality. Aim: Public awareness is highly important to increase screening rate and to decrease mortality from CRC. Methods: We initiated a social program for patients with CRC, which is called “Colorectal Cancer Survivors”. Program contained interactive talks with patients and their relatives during cocktail and lunch in selected five stars hotels. We performed this activity in 2011 and 2012 in Istanbul. We invited patients with CRC who already diagnosed and successfully treated in Istanbul University Institute of Oncology. They were all 5 years or more survivors after surgery alone for stage I and II disease or last chemotherapy cycle for stage III or some stage IV cases. During meetings, surgeons, medical and radiation oncologists shared latest information about the risk factors, prevention and treatment modalities with participants. Media health correspondents were also participated to these activities. We monitored and compared screening rate before and after 2011. As a source, we used the nation-based data of cancer screening of Ministry of Health. Results: In April 30th, 2011, and in March 29th, 2012, 34 survivors joined to this program. We offered “Certificate of 5-Year Survivor” and “Blue Bead” to all patients. Blue Bead is a kind of symbol of hope in Turkey. In 2014, we observed significant increase in CRC screening compared with 2011 in Istanbul and all over the country. Conclusion: Since 2011 until present, there is a significant increase in CRC screening in Turkey. Among many positive factors, some social programs using media such as our “CRC Survivors” program that gives the message that CRC is a treatable and also curable in early stages, may stimulate screening.

The MgO-supported Fe-Co-Mn catalysts, prepared using co-precipitation procedure, were tested for production of light olefins via CO hydrogenation reaction. The effect of a range of drying conditions including drying temperature and drying time on the structure and catalytic performance of Fe-Co-Mn/MgO catalyst for Fischer-Tropsch synthesis was investigated in a fixed bed micro-reactor under the same operational conditions of T = 350 °C, P = 1 bar, H2/CO = 2/1, and GHSV = 4500 h-1. It was found that the catalyst dried at 120 °C for 16 h has shown the best catalytic performance for CO hydrogenation. Furthermore, the effect of drying conditions on different surface reaction rates was also investigated and it was found that the precursors drying conditions influenced the rates of different surface reactions. Characterization of catalyst precursors and calcined samples (fresh and used) was carried out using powder X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Energy Dispersive Spectroscopy (EDS), Brunauer-Emmett-Teller (BET) measurements, Temperature Programmed Reduction (TPR), Thermal Gravimetric Analysis (TGA), and Differential Scanning Calorimetry (DSC). Characterization results showed that different investigated variables (drying conditions) influenced the structure, morphology and catalytic performance of the ternary catalysts.

Constructed wetland is a low cost, effective technology and it is still in the state of improvement to enhance the treatment efficiency, especially in nutrient and trace elements treatment. This study investigated the effect of aerobic and anoxic conditions in Horizontal Subsurface Flow Constructed Wetland (HSFCW) on nutrient, organic, metal and Octylphenol - OP (Endocrine disrupting chemical) treatment. Two HSFCWs were constructed: HSFCW1 with three aerobic compartments; HSFCW2 with two aerobic compartments, one anoxic compartment. The two HSFCWs had the same design parameters (fiters, plants), except oxygen conditions. The results showed that aerobic and anoxic HSFCW may increase the efficiency of Nitrogen removal by 10%, but decreased by 11% in the efficiency of OP treatment (one of the EDCs). The efficiency of treatment of pollutants, including NH4+-N, COD, TP, Mn, Fe, Al and Cu between two HSFCWs were not significantly different; the average efficiency was 99%, 84%, 97%, 96%, 96%, 72% and 73%, respectively. Therefore, the anoxic compartment of HSFCW still provided the effective removal of organic matter, Manuscript received September 29th, 2017; accepted 24th December, 2017 This study was funded by CARE RESCIF under grant number Tc-TTC-2017-05.

Physiotherapy research promotes optimum care for patients through evidence-based physiotherapy practice. Students' attitude towards research motivates them to engage in research, develop research skills and apply research findings in clinical settings to promote positive patients outcome. Aim: The aim of this study is to analyse the attitudes and anxiety of undergraduate Physiotherapy students towards research component. Materials and Methods: A cross-sectional survey was carried out with purposively selected students (n=150) from one physiotherapy college (Third-year BPT, final year BPT and internee). With informed voluntary consent, data on students’ attitude and anxie-ty toward research were collected using Attitudes Toward Research (ATR) scale which was devised by Elena T. Papanastasiou in 2005. ATR consists of 32 items measured on a 7- point Likert scale. A value of 1 indicates a response of ‘strongly disagree’ and a value of 7 corresponds to ‘strongly agree’. Analyses were performed using SPSS version 20. Results: Most of the participants (80%) reported that research is useful for the career. Positive attitude towards research was demonstrated by 69.33% physiotherapy students and 63.33% reported that research plays an im-portant role in professional and personal life. However, a large proportion of students (72.67%) have anxiety towards research and 74% of students reported for research difficulty. Conclusion: Although many of the students have a fa-vourable attitude towards the research and acknowledge its usefulness and benefit to physiotherapy profession, many of them perceived their research course as stressful and have anxiety towards the research.

The present study aimed to evaluate the impact of the Coronavirus disease (COVID-19) pandemic on the urology outpatient clinic and provide objective data for the allocation of the resources during the pandemic. 
 Materials and methods. The patient records who were admitted to our Hospital Urology outpatient clinic during March 20th - May 29th, 2019, and March 20th - May 29th, 2020 has been evaluated and constituted two groups as Non-Pandemic Group and Pandemic Group according to application date. Groups have been compared according to demographic and cohort-specific variables.
 Results. There has been a statistically significant difference between groups according to age, gender, admission, prescription, and hospitalization rates. During the pandemic period, we found that the rates of patient admission, frequency and the number of hospitalizations decreased, and the rate of prescribing increased. Also, we found that male patients aged 18-65 years were admitted more frequently during the pandemic period.
 The analysis of the subgroups constituted according to diagnostic segmentation revealed that the patients with lower urinary tract symptoms and pediatric urology patients decreased while infertility and infection groups were increased. 
 Conclusion. The urology outpatient clinic has been affected by the COVID-19 pandemic from various perspectives. This alteration should take into consideration for the planning of the services during a pandemic.

Full textAbstract:
This chapter describes Islamic capital markets. Led by Malaysia and its distinct Islamic Market, Bursa Malaysia-I, Islamic finance has entered the mainstream of international capital markets, primarily in the form of ‘Islamic bonds’ (sukuk) and fund products. Saudi Arabia, with its well-publicized Saudi Aramco initial public offering (IPO) in 2019, raised, less successfully, a different flag in the international markets. Islamic finance has infiltrated conventional markets too. Non-Islamic issuers, sovereigns, corporates and international institutions, have issued sukuk, attracted by the wash of liquidity and investors in the Gulf region. Indeed, Islamic finance has been rubbing shoulders with modern conventional finance for several decades now. As ‘conventional’ finance has become less ‘conventional’, shari'a compliant finance has become more accepted. Impediments to growth persist; the imperviousness to standardization and the artificiality of the structures underlying the financial products increase costs and possibly risk, making the products uncompetitive. However, cost is not the only consideration in the marketplace. With greater interest in ethical and ESG (environmental, social, and governance) investing, Islamic finance may be the path or the way to future markets.

Abstract This is a brief discussion of the interaction between a first-order system and a higher-order system, resembling system 1 and system 2 in Kahneman (2011). The first-order system of desire and belief may have an important role in first-order functioning essential to survival, but it is not the hero of the story of agency. The higher-order system has the role of evaluating desire and belief, deciding whether desires should be satisfied and whether beliefs should be accepted. That system has access to the states of the first-order system and looping back onto itself to the states of itself. The evaluations of the higher-order system are a source of evidence, as I have argued (Lehrer 2011, 2019), as an evaluator of evidence of reflexive exemplarization. Evaluations and reasonings of the higher-order system form preferences, which are the ultimate explanations of choice in ultimate freedom. It is also a discussion of degrees of freedom suggested by Corlett (2020). The conclusion is that ultimate freedom does not come in degrees. It is ultimate.

Full textAbstract:
Abstract Fatigue has often been described as the most common cause of failure in engineering structures, and designers of pressure vessels and piping have incorporated fatigue considerations into design requirements since the first edition of Section III in 1963. The development of this technology and its application in Section III are discussed in Chapter 39 of the third edition of this publication. Its application in Section XI is discussed in Section 32.3 of this chapter. With the advancement of the state of the art, the ability to recognize how the growth and size of a crack can lead to failure has been enhanced. This technology has been a key aspect of the Section XI flaw evaluation procedures since the 1974 edition was published and will be discussed thoroughly herein. Further advancements in the state-of-the-art in fracture evaluation resulted in the introduction of models for stress corrosion cracking into Section XI in 2001, and since that time additional models have been added and more are planned. This addition gives Section XI flaw evaluations a complete treatment of all the potential modes of cracking that can occur in components, and details will be provided in Section 32.2. Since additional crack growth data, for both fatigue and stress corrosion cracking, is periodically made available on a regular basis from additional research testing, the models contained in Section XI are regularly reviewed and updated to ensure their applicability, accuracy, and reflection of the latest known material behaviors. This improved knowledge may lead to more conservative models for crack growth over time. To accommodate such situations, Section XI has adopted an approach to conservatively account for potential increases in crack growth predictions with augmented examinations. The rules of IWB-3600 require that augmented (additional) examinations must be performed at an accelerated pace for situations where a flaw indication was accepted by analytical evaluation. This rule also protects against NDE uncertainties at the location of interest. The nomenclature used here will be identical to that used in Section XI; any nomenclature that is not present in Section XI will be explained as it appears. This chapter has been updated using the 2019 Code edition. History Warren H. Bamford is the original author of this chapter and has since revised it for all of the subsequent editions including the current online edition.

Full textAbstract:
Abstract Although microbiologically influenced corrosion (MIC) in pipelines is challenging to mitigate, it is generally accepted that pigging, a mechanical cleaning process that removes water, scales and other solids from the pipeline surface, is an effective method to control biofilm formation. However, not all pipelines can be pigged and as such biofilm development may occur undisturbed from mechanical impacts. Regardless of the absence or presence of a mechanical cleaning program, oilfield biofilms are often exposed to continuously injected, film-forming corrosion inhibitors (CI) which are used to mitigate acid gas corrosion in pipelines. To date, the individual and combined effects of pigging and CI injection on biofilm formation and subsequent corrosion have not been well-studied. To this end, corrosive consortia consisting of sulfate-reducing bacteria and methanogenic archaea were grown as biofilms on carbon steel coupons under defined laboratory conditions. Once biofilms were established, the coupons were exposed to one of the following corrosion mitigation treatments: (1) simulated pigging using a wire brush, (2) exposure to CI at a concentration of 50 ppm, or (3) a combination of both treatments. Fundamentally different effects of CI on MIC were observed depending on whether these chemicals were applied to pre-formed biofilms or to previously mechanically cleaned steel surfaces.

"Implications of Using the Fugacity (Activity in the Gas Phase) of the Acid Gases in the Design of Qualification Testing of Oilfield Tubular Materials." In CORROSION 2019. NACE International, 2019. https://doi.org/10.5006/c2019-12939.
Full textAbstract:
Abstract The transition from partial pressure to fugacity in the assessment of acid gas activity (concentration) for the design of qualification testing of metals to be used in sour service according to MR0175/ISO 151561,2,3 entails a number of important consequences. This transition came about in the wake of oil and gas production moving off-shore to ever higher pressures and temperatures. It was recognized that multiplying total pressure by the mol fraction of H2S in the “gas phase” could no longer reflect the physicochemical realities with respect to the reactions between H2S and the metal surfaces. As a consequence, it was proposed that the activity of H2S in the gas phase should be replaced by the activity of H2S in the aqueous phase. This change in paradigm had already been accepted in the ISO Standard but not implemented. Nevertheless, it stands to reason that the dissolved H2S is the active corrosion vector, rather than the H2S in the gas phase. An unintended consequence of this shift in thinking lies in the fact that a very large number of Heritage Metals have been qualified for partial pressure criteria as specified in MR0175/ISO-15156 by the use of the Crolet Diagram, i.e. as function of pH vs. pH2S. In order to overcome this difficulty, the H2S concentration in the solution of the test procedure used at the time is compared with the H2S concentration in solution under field conditions. It is invariably found, judging by the H2S concentration in solution, that field conditions are less aggressive than the conditions for which the test has been designed. Using a fugacity corrected Henry solubility constant ([mol/L.at]) for field conditions, together with the H2S concentration in the test solution one can determine the corresponding nominal H2S partial pressure for field conditions. One then finds that this value is higher than the one for which the test has been designed. As a practical matter, one concludes that higher grade materials, e.g. P-110 or Q-125, may be used to much higher H2S partial pressures than the ones the tests may have been designed for. For single phase system (total pressures in excess of ~ 700 bar (10,000 psi), not discussed here, a similar paradigm would hold, although based only on the equilibrium of H2S between the oil and brine phases.

Full textAbstract:
Abstract External corrosion on buried pipe steels has been demonstrated to be a major threat to pipeline integrity. Although it has been extensively investigated and well understood electrochemically, there is no particular corrosion rate model that is widely accepted by industry due to the complexities associated with coating performance, and heterogeneity of the soil environment (including bacteria, drainage, bulk resistivity, CP level, etc.). This paper demonstrates that the severity of external corrosion on Polyethylene (PE) tape coated oil pipe is exacerbated by the proximity to upstream (U/S) pump stations, and suggests mechanistic explanations related to pressure fluctuations. External corrosion features reported by the most recent In-Line Inspection (ILI) Ultrasonic Wall Measurement (UTWM) tools for three oil pipelines were correlated with the distance to U/S pump stations. UTWM ILI data is used as it includes features that are located under repair sleeves. These three oil pipelines with PE coating were investigated for a total length of approximately 3100 km. The pipelines have been in service for more than 40 years. One of the pipelines has experienced reversed flow operation. Analysis of the results shows that external corrosion features with depths < 20% Wall Thickness (WT) reported by UTWM tools are distributed uniformly along the pipelines. However, a clear increase in the frequency of corrosion features with depths >= 20%WT is seen within 10 km from the U/S pump station. There is a pronounced increase in the density of deeper feature classes in the same region. This phenomenon was also observed on the third oil pipeline with reversed flow directions. In addition, this trend is further validated by the distribution of field excavations triggered by external corrosion. Based on these data, it is evident that the frequency and severity of external corrosion on these tape coated pipelines is positively correlated to U/S pump station proximity. Possible mechanisms may include mechano-electrochemistry, and pressure fluctuations that facilitate electrochemical processes and/or PE tape coating damage: 1) Pressure fluctuations increase dislocation density and thus electrochemical potential ahead of the corrosion tip due to stress concentration. 2) Pressure fluctuations may refresh the electrochemical environments against the pipe surface and thus exacerbate corrosion. 3) The PE coating damage is accelerated (mechanically) by pressure fluctuations. The findings in this paper could help External Corrosion Direct Assessment (ECDA) locate severe corrosion features, especially for lines that are non-piggable. Also, these discoveries can provide guidance for future research and pipeline integrity management with external corrosion.

Full textAbstract:
The author stops attention on the famous sword that was discovered in the 80ies of 20th century in grave No 55 of the Garabonc I necropolis, Hungary. In 2011, the author wrote an article in attempt to systematize a few types of Byzantine swords. One of the types of swords he called „Garabonc type” – according to this weapon found in a sure archeological context. To date, „Garabonc type” is represented by six pieces – swords and/ or their details. The swords of this type are one-handed and consist of a blade with swordguards and hemispherical pommel on top. According the author, the closest artistic parallels to the „Garabonc type” of swords are depicted in famous manuscript of „The Homilies of Saint Gregory of Nazianzus” that was completed in Constantinople in 879–882, where similar swords are shown in four folios of the book. The discussed here sword type may be determined as a Byzantine invention and maybe it was produced in the empire. This has also been proved by some other works of art, although dated to a later period (9th–10th centuries). The author, accepted for most possible the hypothesis proposed by the first researcher B. M. Szőke that the Garabonc sword was transferred in the lands south of Balaton Lake by Bulgarsmercenaries. Most possibility that, they have joined the retinue of Prince Pribina, the head of the Blatna Principality and his son Chezil around the second third of 9th century.

An accurate prediction of the wave loading on the columns of any offshore structure is an integral part of the design / re-assessment process. Earlier studies have investigated the nonlinear loads on single columns covering a wide range of diameters (expressed as a ratio of the incident wave length) and addressing a variety of incident wave steepness. As a result, it is generally accepted that wave-structure interaction effects can be important even outside the diffraction regime and may be one possible cause of structural dynamic response. The importance of wave-structure and wave-wave interaction effects will again be highlighted in the present study; the emphasis of the work being the occurrence of wave impacts on the columns of a gravity-based structure in random seas involving very large, steep waves. This paper presents the results of an experimental study of a gravity based structure in a severe wave climate. The structure comprises an arrangement of storage caissons located on the sea bed in relatively shallow water, with four large diameter surface-piercing columns. The primary purpose of the present paper is to provide a comparison between the incident waves and the measured loads. This shows that robust predictions of the slamming load cannot be made without taking into account the geometry of the structure, including that of the underlying caissons. It is also shown that the largest loads frequently do not correspond to the tallest or steepest incident waves. This emphasizes the importance of correctly incorporating the nonlinear wave-wave interactions and hence the need to undertake long random wave tests in offshore engineering design.

Transmission pipelines, which are usually subjected to a variety of loads ranging from internal pressure to external pressure ground loading, transport gases and liquids at high pressures. Furthermore, the pipelines exhibit various forms of damage from environmentally induced cracks to manufacture and operation induced cracks. Therefore, it is of great engineering significance to establish acceptable levels for the flaws revealed. The acceptance levels for flaws are based on the concept of fitness for purpose. By this principle, a particular fabrication is considered to be adequate, provided that the conditions to cause failure are not reached. Less severe flaws are accepted without further consideration. Moreover, if flaws are more severe, rejection is not necessarily automatic. Based on fitness for purpose, decisions on whether rejection or repair might be justified, either in the light of previously documented experience with similar material, stress and environmental combinations or on the basis of an engineering critical assessment (ECA). The present paper focuses on two objectives. Firstly, the remaining strength and fracture toughness of the pipeline with defects along the longitudinal direction of the pipeline have been obtained. Secondly, the utilizing reliability of the pipeline, which has been tested to have inner flaws and to what extent this kind of defects may exist in the pipeline purchased from the same manufacturer, has been evaluated. Based upon the description of the defects found in the pipeline, the remaining strength assessment is performed with the application of different codes such as B31G and DNV. Also, an ECA sample for the embedded flaw in plates will be performed according to the existing BS 7910 methodology. The initial crack depth is 2a and the width is 2c. According to the BS7910 standard, the fracture and fatigue assessment is applied to obtain the fracture ratio Kr and the load ratio Lr. A 4th Runge-Kutta method is used to calculate crack growth rate da/dN and the final size of the crack af and cf. Also the Failure Assessment Diagram (FAD) can be changed according to the material stress-strain curve. This work might provide useful reference to safety design and application of pipelines.

The offshore industry is in constant evolution due to the need of reach increasing water depths for new oil fields exploitation. In this scenario, not only new types of platforms are being designed, but also new types of risers, including flexible pipes and new umbilical cable configurations. The greatest difficulty to generate a new concept for a riser is to determine if it is viable or not. Flexible pipes and umbilical cables are complicated to model, due to the interactions between their layers and the large number of possible arrangements. To predict the behavior of flexible pipes and umbilical cables, adequate models are necessary. One can rely on finite element models, which show a great difficulty in mesh generation and convergence (specially due to the contact pairs). One can also rely on analytical models, which have many limitations due to simplifications (even though they are necessary). Another possible approach is to define macro elements, which represent a component, instead of classical finite elements (such as tetrahedric elements). Related to that approach, this paper presents a tubular element, which describes a cylinder with isotropic properties and can accept various sorts of loads. This element has its displacements and loads described using Fourier series and, for each term of the series, a solution is obtained. The effect is then superposed and the complete solution is obtained. This formulation is implemented and their results compared to those obtained by a classical finite element modeling tool, with good agreement.

Full textAbstract:
Abstract A free standing, slender body may experience rocking motion followed by overturning when it is subject to strong seismic motions. When the free body is submerged in water, it will also be subject to lateral forces acting along the side of the free body as a result of water sloshing. This highly non-linear situation is of particular interest to engineers in the nuclear industry in need to assess the stability of transfer casks containing spent fuel and submerged in a confined pit or pool. In this work, a three-dimensional finite element dynamic transient model of a free standing cask is developed and analyzed using ANSYS. Both dry and submerged conditions are considered. Cask to floor friction, buoyancy force, and sloshing are accounted for in the assessment. The model is validated against well-accepted contributions on sloshing and rocking provided by G.W. Housner.

Different semantics of abstract Argumentation Frameworks (AFs) provide different levels of decisiveness for reasoning about the acceptability of conflicting arguments.The stable semantics is useful for applications requiring a high level of decisiveness, as it assigns to each argument the label "accepted" or the label "rejected". Unfortunately, stable labellings are not guaranteed to exist, thus raising the question as to which parts of AFs are responsible for the non-existence. In this paper, we address this question by investigating a more general question concerning preferred labellings (which may be less decisive than stable labellings but are always guaranteed to exist), namely why a given preferred labelling may not be stable and thus undecided on some arguments. In particular, (1) we give various characterisations of parts of an AF, based on the given preferred labelling, and (2) we show that these parts are indeed responsible for the undecisiveness if the preferred labelling is not stable. We then use these characterisations to explain the non-existence of stable labellings.

Full textAbstract:
The aim of this report is to explore Northern Ireland take home food and drink purchases in 2016, 2019 and 2020. In 2020, due to the Covid-19 restrictions, the purchasing of take home food and drink may have been impacted. Therefore, this report will examine the data to identify any key trends in purchasing in 2016 and 2019 (before the Covid-19 pandemic), and then between 2019 and 2020. However, as this study is based on observations, it is not possible to know what may have caused changes in take home food and drink purchasing. It is important to remember that data in 2019 and 2020 are not directly comparable due to Covid-19 restrictions, as the majority of the out of home sector was closed and therefore an increase in take home purchasing is expected to replace the food and drink that would have been purchased outside of the home. The analyses within this report have been conducted by the FSA in Northern Ireland with guidance from Kantar. Data presented within this report was collected in 2016 (52 weeks ending 1st January 2017), 2019 (52 weeks ending 29th December 2019) and 2020 (52 weeks ending 27th December 2020).
