RP parallel robot with flexible platform and prismatic joint
Authors: Sharifnia Mahdi , Akbarzadeh Alireza
Published: April 2014

An analytical solution for vibration of a parallel robot where its end-effector is flexible and has a passive prismatic joint(s) has not been presented before. In this research vibration analysis of a PR-PRP parallel robot using an analytical method is investigated. The PR-PRP parallel robot has two planar degrees of freedom and moves by means of two active prismatic joints. The robot moving platform is a flexible link with one passive revolute and one passive prismatic joint. First, the motion equation for a flexible link with the passive prismatic joint is developed. The motion equation is solved by employing an approximate analytical method called “constrained assumed modes method”. A time-variant constraint is written for the passive prismatic joint. The developed model allows for inclusion of the effect of physical length for the passive prismatic joint in contact with the moving platform on the vibration response of the system. For verification of the presented model and solution, three case studies are presented and results of the analytical solution are compared with results of a commercial finite element method software. For each case study, two different lengths for the passive prismatic joint are considered. Finally, active vibration control is performed for an applicable motion of the robot using the proportional-integral-derivative controller.
Addressing the attrition between the conflicting influences experienced by teachers on the interface between Foundation Stage and Key Stage One
Authors: Orlandi Kathleen J
Published: April 2014

This article examines the use of naturalistic observations to explore children’s experiences in the early years at school, from their perspectives. It looks at the difficulties encountered in determining the significance of observed behaviours in relation to (a) experiences and (b) impact of those experiences. Often the children were not satisfied with their experiences. Teachers of Foundation Stage and Key Stage One were faced with a dilemma. They have three competing areas of pressure on their practice. They are encouraged to follow the interests and needs of the children, in keeping with an early years approach; they have knowledge and understanding of the long-term impact of various aspects of provision; they are subject to short-term attainment targets which, arguably, exert pressure to work towards short-term goals that may result in provision which disregards long-term consequences. It suggests the need for a critically reflective approach to professional development for teachers to enable them to address the conflicting pressures. This is essential if teachers are to feel confident and empowered, and if children are to have fulfilling and fruitful experiences.
Mixed Methods in Indigenous Research
Authors: Chilisa Bagele , Tsheko Gaelebale N.
Published: April 2014

Indigenous communities raise concerns that they are overresearched and tired of research always asking the same questions and reproducing the same answers, thus pressuring researchers to open the discourse on mixed methods research so as to enable new debates and approaches to emerge. A postcolonial indigenous paradigm provides a theoretical framework that informed a mixed methods research approach to design and test the efficacy of a school-based risk-reduction intervention for 14- to 17-year-old adolescents in Botswana. Indigenous methods were used to collect cultural knowledge and to build relationships; these approaches allowed for the integration of the largely marginalized knowledge systems with dominant knowledge systems through a decolonization and indigenization research process.

Authors: Madaus Joseph W. , Grigal Meg , Hughes Carolyn
Published: April 2014

Few students with disabilities from high-poverty backgrounds attend college. We discuss the effects of disability and growing up in poverty on expectations for postsecondary education attendance. We describe the limiting effects of attending high-poverty high schools on student achievement followed by challenges faced by low-income students with disabilities in accessing and completing college programs including the role of federal student aid programs. Finally, we discuss the limited employment outcomes for adults with disabilities, in particular, those from high-poverty backgrounds who have not completed college. We conclude with implications and recommendations for policy.

Fast anodization fabrication of AAO and barrier perforation process on ITO glass
Authors: Liu Sida , Xiong Zuzhou , Zhu Changqing , Li Ma , Zheng Maojun , Shen Wenzhong
Published: April 2014

Thin films of porous anodic aluminum oxide (AAO) on tin-doped indium oxide (ITO) substrates were fabricated through evaporation of a 1,000- to 2,000-nm-thick Al, followed by anodization with different durations, electrolytes, and pore widening. A faster method to obtain AAO on ITO substrates has been developed, which with 2.5 vol.% phosphoric acid at a voltage of 195 V at 269 K. It was found that the height of AAO films increased initially and then decreased with the increase of the anodizing time. Especially, the barrier layers can be removed by extending the anodizing duration, which is very useful for obtaining perforation AAO and will broaden the application of AAO on ITO substrates.

Authors: Hope Carol , Estrada Nicollete , Weir Charlene , Teng Chia-Chen , Damal Kavitha , Sauer Brian C
Published: April 2014

Background

Delirium is a life-threatening, clinical syndrome common among the elderly and hospitalized patients. Delirium is under-recognized and misdiagnosed, complicating efforts to study the epidemiology and construct appropriate decision support to improve patient care. This study was primarily conducted to realize how providers documented confirmed cases of delirium in electronic health records as a preliminary step for using computerized methods to identify patients with delirium from electronic health records.

Methods

The Mental Health Consult (MHC) team reported cases of delirium to the study team during a 6-month study period (December 1, 2009 - May 31, 2010). A chart extraction tool was developed to abstract documentation of diagnosis, signs and symptoms and known risk factors of delirium. A nurse practitioner, and a clinical pharmacist independently reviewed clinical notes during each patients hospital stay to determine if delirium and or sign and symptoms of delirium were documented.

Results

The MHC team reported 25 cases of delirium. When excluding MHC team notes, delirium was documented for 5 of the 25 patients (one reported case in a physician’s note, four in discharge summaries). Delirium was ICD-9 Coded for 7 of the 25 cases. Signs and symptoms associated with delirium were characterized in 8 physician notes, 11 discharge summaries, and 14 nursing notes, accounting for 16 of the 25 cases with identified delirium.

Conclusions

Documentation of delirium is highly inconsistent even with a confirmed diagnosis. Hence, efforts to use existing data to precisely estimate the prevalence of delirium or to conduct epidemiological studies based on medical records will be challenging.
Immunosuppressive monocytes: possible homeostatic mechanism to restrain chronic intestinal inflammation
Authors: Kurmaeva Elvira , Bhattacharya Dhruva , Goodman Wendy , Omenetti Sara , Merendino Amber , Berney Seth , Pizarro Theresa , Ostanin Dmitry V
Published: April 2014

Chronic colitis is accompanied by extensive myelopoiesis and accumulation of CD11b+Gr-1+ cells in spleens and secondary lymphoid tissues. Although cells with similar phenotype have been described in cancer, chronic infection, or autoimmunity, where they were associated with suppression of T cell responses, little is known regarding how these cells affect CD4 T cell responses in the context of chronic intestinal inflammation. Therefore, we undertook this study to characterize the interplay between colitis-induced myeloid cells and CD4 T cell. Within the CD11b+Gr-1+ population, only monocytes (Ly6GnegLy6Chigh) but not other myeloid cell subsets suppressed proliferation and production of cytokines by CD4 T cells. Suppression was mediated by cell-contact, NO and partially by IFN-γ and PGs. Interestingly, Ly6Chigh MDCs, isolated from colitic colons, showed up-regulation of iNOS and arginase-1 and were more potent suppressors than those isolated from spleen. On a single-cell level, MDCs inhibited Th1 responses but enhanced generation of foxp3+ T cells. MDCs, cocultured with activated/Teffs, isolated from inflamed colons under hypoxic (1% O2) conditions typical for the inflamed intestine, suppressed proliferation but not their production of proinflammatory cytokines and chemokines. Taken together, expansion of monocytes and MDCs and activation of their suppressive properties may represent a homeostatic mechanism aimed at restraining excessive T cell activation during chronic inflammatory settings. The contribution of immunosuppressive monocytes/MDCs to chronic colitis and their role in shaping T cell responses in vivo require further investigation.
The Geopolitical Role of Cyprus in the Wider Context of the European Union

Offshore hydrocarbon discoveries in Cyprus’s exclusive economic zone can transform the island into a regional energy hub and an important pillar for Europe’s energy security and diversification. At the same time, these discoveries can create an additional impetus to end the long division of the island.
Cyprus 1974: Turkey’s Military Success Followed by Political Stalemate
Authors: Bahcheli Tozun
Published: April 2014

Turkey achieved major gains through its military intervention in Cyprus following the Greek junta’s coup against Cypriot president Archbishop Makarios in July 1974. Yet Turkey has been repeatedly frustrated by its inability to capitalize on its military accomplishment and to achieve a political settlement that adequately safeguards Turkish and Turkish-Cypriot interests. This essay traces Turkish policy in Cyprus since 1974 and explains how the Turkish government led by the Justice and Development Party revised Ankara’s Cyprus policy to advance Turkey’s accession to the European Union. The fading prospects of Turkey’s EU membership have diminished Ankara’s interest in playing an active role in achieving a Cyprus settlement.
Specification of regional intestinal stem cell identity during Drosophila metamorphosis
Authors: Driver Ian , Ohlstein Benjamin
Published: April 2014

In the adult Drosophila midgut the bone morphogenetic protein (BMP) signaling pathway is required to specify and maintain the acid-secreting region of the midgut known as the copper cell region (CCR). BMP signaling is also involved in the modulation of intestinal stem cell (ISC) proliferation in response to injury. How ISCs are able to respond to the same signaling pathway in a regionally different manner is currently unknown. Here, we show that dual use of the BMP signaling pathway in the midgut is possible because BMP signals are only capable of transforming ISC and enterocyte identity during a defined window of metamorphosis. ISC heterogeneity is established prior to adulthood and then maintained in cooperation with regional signals from surrounding tissue. Our data provide a conceptual framework for how other tissues maintained by regional stem cells might be patterned and establishes the pupal and adult midgut as a novel genetic platform for identifying genes necessary for regional stem cell specification and maintenance.

Published: April 2014

Bowl-like carbon particles with a controlled morphology and porous structure were synthesized via carbonization of the post-treated polymer composite particles. The obtained bowl-like carbon particles had a uniform, monodisperse and mesoporous structure with a narrow pore size distribution. The pH value in the post-treatment process played an important role in the formation of the bowl-like morphology and had a remarkable influence on the pore structure, which can control the morphology and pore structure of the carbon particles.
Feasibility of Rapid in vitro Estimation of Haematocrit in Cattle by Using Short-Wavelength near Infrared Spectroscopy
Authors: Ikehata Akifumi , Luo Xuan , Sashida Kunio , Park Shanji , Okura Tsutomu , Terada Yutaka
Published: April 2014

Feasibility of rapid estimation of haematocrit (Ht) in cattle was studied by near infrared (NIR) spectroscopy in the short wavelength (SW, 700–1050 nm) region. The blood samples, held in standard vacuum blood collection tubes, were measured by a custom-designed, portable NIR spectrometer equipped with a Li-ion battery. Sufficient evidence for estimation of Ht was presented by searching the informative wavelength regions and comparing the root mean square errors of prediction ( RMSEP) with moving window partial least square regression (MW-PLSR). The result of the MW-PLSR indicated the importance of the water absorption band with a maximum at 970 nm and the absorption band due to deoxy-haemoglobin with a maximum at 760 nm in estimating Ht. Due to light scattering from blood cells, the optical density of the blood does not have a linear relationship to Ht, especially in the low Ht range. In order to improve the prediction accuracy of Ht, an appropriate transformation was proposed for Ht. We confirmed the usefulness of the SW-NIR in estimating Ht, and hope that this technique will replace the time-consuming conventional centrifuge method.
Analysis of Vibration Reduction Properties of Rail Damping under High-Speed Vehicle Moving Load
Authors: Cui Rixin , Gao Liang , Zhong Yanglong , Xin Tao
Published: April 2014

Rail damping is an active and effective control method for mitigating railway vibration and noise at the source. In order to investigate the applicability of rail damping to high-speed railway, a vehicle-ballastless slab track-bridge coupling dynamic model was established and the vibration reduction effect of rail damping at bridge mid-span, bridge pier and beam gap under a high-speed vehicle moving load was analyzed. The results show that: the max vibration acceleration of ballastless track and bridge with rail damping are obviously decreased, and the duration time of structure vibration is also shortened. The vibration reduction effect of rail damping at bridge mid-span is more significant than that at bridge pier. In the working frequency range of rail damping, the acceleration vibration level of the rail can be reduced by 2–5dB, and the vibration of ballastless track slab and bridge also can be decreased in middle and high frequency range.
Art, politics and the public sphere
Authors: Gielen Pascal
Published: April 2014

The relationship between contemporary art in the tradition of the avant-garde, politics and the public domain is the subject of this article. By looking at critical social theory, especially the work of Chantal Mouffe, the relationship between politics and the public sphere will be explored. Via the work of Paulo Virno and Niklas Luhmann, I will get more grip on avant-garde art’s functioning in society and its relationship with politics and the public sphere. By discussing the insights of these theorists it will be argued that the contemporary art world – as a sphere of concrete museums, biennials, exhibitions, etc. form a public sphere of many different singularities, artistic styles and sometimes even conflicting paradigms and cultures. Contrary to the classic Habermasian view (1989) this public sphere is seen as an agonistic one in which a multitude of conflicting voices coexist. Contemporary art in the tradition of the avant-garde time and again posits a ‘dismeasure’ within a culture and will therefore take up a minority position within a society. This does however allow this art scene to become a model for a specific interpretation of democracy, especially a minority democracy, in which collective support for emerging singular voices has to be gained time and again. The argumentation needed to grow from the singular base to a somewhat or very much larger collective base is the core of a minority democracy within an agonistic public sphere. This view is at odds with the concept of public sphere mostly held nowadays according to the rules of the dominant liberal representative democracy, which, after all, found its legitimacy on anonymous numbers (the majority of votes) and the third way of compromise. But also hegemonic political regimes of today, such as neo-liberalism and the upcoming neo-nationalism, are concerned about agonistic spheres, because from their perspective they are still difficult to control. It is one of the reasons why such ideologies hardly know how to respond to contemporary avant-garde art.

It is well known that metabolic syndrome (MS) substantially increases the risk of the development of cardiovascular disease,
type 2 diabetes and associated mortality. This makes the search of markers of predisposition to MS and predictors of visceral involvement
in people with normal body mass an extremely pressing problem, as it is the basis of early prophylaxis. The aim of the research
was to determine the early (premorbid) markers of MS. Patients: 458 practically healthy young people aged 18-25. Methods: anthropometric
parameters (body mass index, waist circumference), fat component in body composition (FCBC) «BF-306 OMRON»
(Japan), lipid (Triglyceride, Total Cholesterol, LDL-Cholesterol, LHL-Cholesterol) and glucose metabolism parameters (Glucose,
Immunoreactive insulin, C-peptide, Insulin resistance index HOMA-IR). Results. We found a close correlation of FCBC with glucose
(r=0,564-0,427; p=0,01-0,04) and lipid (r=0,547-0,734; p=0,001-0,04) metabolic parameters inherent to MS in young people with
normal body mass, which made it possible to consider FCBC as a marker premorbidity of MS (sensitivity - 100%, specificity - 96%).
Herein we present an algorithm of diagnostic and tactic activities, which can be used in patients of high risk group for development
of MS, including measures of early prophylaxis and preventive therapy.

Authors: Gerasimenko O A , Pigarova E , Dzeranova L K
Published: April 2014

Bromocriptine is a sympatholytic agonist of dopamine receptors, which is now proposed for treatment of type 2 diabetes mellitus. In animal studies bromocriptine elevates the decreased levels of dopamine in hypothalamus and blocks excessive sympathetic innervations in central nervous system that results in decrease of postprandial glucose. Bromocriptine decreases hepatic glucose production and increases insulin secretion and muscle insulin sensitivity. This article reviews experimental and clinical data on the use of bromocriptine for treatment of type 2 diabetes mellitus

The use of intragastric balloons in patients with morbid obesity (BMI>40) and superobesity (BMI>50) as the only method of treatment did not prove its effectiveness because of high rates of disease relapses. The article presents data showing that the fist line body mass lowering therapy with intragastric balloon before proceeding to bariatric sugery is effective in 78% patients with superobesity in aspects of lowering surgical and anesthesiological risks. Stopping treatment at the point of removal of intragastric balloon is associated with high risk of recurrence of obesity and its comorbid conditions. The use of intragastric balloons in group of high risk patients optimizes the process of selection of candidates for surgical treatment among patients with superobesity

Uvod: Kategorizirane udeležence (paciente) množične nesreče je treba označiti, da bodo njihove prioritete prepoznali ostali udeleženci v verigi reševanja. Cilj raziskave je bil proučiti uporabnost triažnega kartona, ki je pri množičnih nesrečah v Republiki Sloveniji predpisan s Pravilnikom o službi nujne medicinske pomoči.Metode: Podatki so bili zbrani s pomočjo strukturiranega vprašalnika. V raziskavo je bilo  zajetih sedem enot nujne medicinske pomoči na primarni ravni zdravstvene dejavnosti (Gorenjska regija). Med zaposlene v nujni medicinski pomoči je bilo razdeljenih 136 vprašalnikov, pravilno izpolnjenih je bilo 94. Podatki so bili obdelani z opisno in bivariatno statistiko.Rezultati: Raziskava je pokazala, da anketiranci niso prepričani v svojo usposobljenost za uporabo predpisanega triažnega kartona (x = 3,26) ter da triažni karton ni popolnoma neuporaben triažni pripomoček, a ima pomanjkljivosti (x = 3,43). Anketiranci menijo, da bi triažni karton moral imeti možnost označevanja po barvi triažne kategorije (x = 4,00) ter možnost spreminjanja kategorije pacienta, če se le-ta med obravnavo spremeni (x = 3,99). Glede na čas delovanja anketirancev na področju nujne medicinske pomoči se razlikujejo njihova mnenja o potrebnosti triažnih kartonov (p = 0,05) ter usposobljenosti za izvajanje in dokumentiranje triaže (p = 0,04). Anketiranci z daljšo delovno dobo so izrazili statistično značilno večje strinjanje z obema trditvama.Diskusija in zaključek: V prihodnosti bo treba izboljšati raven usposobljenosti izvajalcev nujne medicinske pomoči za uporabo predpisanega triažnega kartona. V Sloveniji potrebujemo vrsto triažnega kartona, ki bo zadostovala trenutnim smernicam posredovanja ob množičnih nesrečah. Raziskava pokaže smiselnost nadaljnjega raziskovanja tega področja.
Vices and Virtues of Misguided Replications: The Case of Asymmetric Dominance
Authors: Simonson Itamar
Published: April 2014

The likelihood of replicating an effect such as asymmetric dominance (AD) largely depends on other, usually more important choice drivers (e.g., attributes, values). Accordingly, it is not surprising that the AD effect is often not observed when other choice drivers have greater impact and/or when the AD configuration is unlikely to be perceived. However, when price is an attribute (and in many other cases), the AD effect is often observed in both properly designed studies and the real world. The author notes that Frederick, Lee, and Baskin (2014) raise important questions, but they would have made a greater contribution had they (1) systematically studied the drivers of AD perceptions, (2) more accurately tried to replicate previous AD effect demonstrations, and (3) systematically studied the repulsion effect. The author also briefly comments on the Yang and Lynn (2014) studies, which he asserts did not test the AD effect properly in most cases.

Authors: Newman-Toker David E. , Moy Ernest , Valente Ernest , Coffey Rosanna , Hines Anika L.
Published: April 2014

Background: Some cerebrovascular events are not diagnosed promptly, potentially resulting in death or disability from missed treatments. We sought to estimate the frequency of missed stroke and examine associations with patient, emergency department (ED), and hospital characteristics.

Methods: Cross-sectional analysis using linked inpatient discharge and ED visit records from the 2009 Healthcare Cost and Utilization Project State Inpatient Databases and 2008–2009 State ED Databases across nine US states. We identified adult patients admitted for stroke with a treat-and-release ED visit in the prior 30 days, considering those given a non-cerebrovascular diagnosis as probable (benign headache or dizziness diagnosis) or potential (any other diagnosis) missed strokes.

Results: There were 23,809 potential and 2243 probable missed strokes representing 12.7% and 1.2% of stroke admissions, respectively. Missed hemorrhages (n=406) were linked to headache while missed ischemic strokes (n=1435) and transient ischemic attacks (n=402) were linked to headache or dizziness. Odds of a probable misdiagnosis were lower among men (OR 0.75), older individuals (18–44 years [base]; 45–64:OR 0.43; 65–74:OR 0.28; ≥75:OR 0.19), and Medicare (OR 0.66) or Medicaid (OR 0.70) recipients compared to privately insured patients. Odds were higher among Blacks (OR 1.18), Asian/Pacific Islanders (OR 1.29), and Hispanics (OR 1.30). Odds were higher in non-teaching hospitals (OR 1.45) and low-volume hospitals (OR 1.57).

Conclusions: We estimate 15,000–165,000 misdiagnosed cerebrovascular events annually in US EDs, disproportionately presenting with headache or dizziness. Physicians evaluating these symptoms should be particularly attuned to the possibility of stroke in younger, female, and non-White patients.
Experimental validation of green wood peeling assisted by IR heating – some considerations of the analytical system design
Authors: Dupleix Anna , Batsale Jean-Christophe , Kusiak Andrzej , Hughes Mark , Denaud Louis Etienne
Published: April 2014

The results of a 2D simulation model have been validated by experimental data to check the possibility of infrared (IR) heating of rotating green logs in the course of veneer production. The assumption that the experimental situation can be described by simplified analytical solutions has been confirmed. In the knowledge of the thermal and physical characteristics of green wood, two methods are now available to calculate rapidly the temperature within the wood log and the maximum surface temperature reached by a green log rotating under an IR heating source: (1) by numerical simulation and (2) by analytical equations, which are simpler than the computationally intensive finite element method. Experimental results, validated by both methods, show that an IR heating system as part of an industrial peeling machine would not warm-up green wood to the required peeling temperature at current peeling speeds.

Various lignin determination methods have been applied to hemicellulose-rich wood extracts obtained after pressurized hot-water extraction (PHWE) and membrane ultrafiltration (UF). In focus were the chlorine number (Cl no.) method, the acetyl bromide method, and the four modifications of the Klason lignin determination, such as the KCL, TAPPI, LAP, and Goldschmid methods. The furfural (F) and hydroxymethylfurfural (HMF) concentrations in the acid hydrolysates were also determined. The mass balances of the fraction were calculated with respect to the contents of dry solids and lignin, including the acid-soluble lignin. The reliability of the methods was evaluated based on the lignin mass balances and the gross chemical composition of the extracts. Although the results were dependent on the method applied, the lignin mass balance calculations yielded similar results in general.
The case of humor in the Malaysian House of Representatives
Authors: Yoong David
Published: April 2014

Being one of the highest public offices, parliamentary businesses are governed by rules and protocols that severely limit the behavioral conduct of Members of Parliament (MPs). MPs must modulate their behavior to the expectations of parliamentary practices. Hence, they cannot behave as they would in informal settings when parliament is in session. Based on his or her discretion, the Chair may subject MPs who violate these written (and unwritten) rules and protocols to censure and punishments. Since MPs are expected to behave formally and avoid being emotional in order to create an impression of objectivity and distinguished professionalism, it is worth asking whether humor is a form of disorderly practice in parliaments. In this paper, I argue that it is, and that the disorderliness of humor may either be acceptable or unacceptable depending on certain parameters. Analyzing instances of humor in the Malaysian House of Representatives (
Passive Microextractor with Internal Fluid Recirculation for Two Immiscible Liquids
Authors: Xu Cong , Wang Jiao
Published: April 2014

A microextractor comprising an inlet channel, a mixing chamber, two feedback channels, and an outlet channel and having no moving parts was designed for immiscible liquid–liquid extraction. Two liquids were mixed passively without any external energy input, and the extraction was completed in the microextractor. The extractor performance with or without a splitter was investigated by visualization and mass transfer experiments. Two mixing mechanisms were observed: (i) molecular diffusion at lower Reynolds number and (ii) chaotic advection at higher Reynolds number. The transition point between the two mechanisms was at Reynolds numbers 375.2 and 179.9 for the aqueous phase (3 mol/L HNO3 solution) and the organic phase (30% tributyl phosphate (TBP)–kerosene solution), respectively. In the chaotic advection mode, two vortexes rotating in opposite directions were formed on both sides of the main flow, which enhanced the mass transfer between the two liquids. Mass transfer between the 3 mol/L HNO3 and 30% TBP–kerosene solutions was achieved with an efficiency of 92.8% at the extractor exit when the extractor operated in the chaotic advection mode.
Modeling the Industrial Propylene–Ethylene Copolymerization FBR at Emergency Accidents
Authors: Zhang Xin-Wen , Luo Zheng-Hong
Published: April 2014

In order to quantitatively describe the pressure change during the copolymerization in industrial fluidized bed reactors, a dynamic reactor model was developed according to the mass and energy balances as well as real gas state-equation and copolymerization kinetics. Furthermore, in order to inspect the performance of pressure relief devices in response to the accident conditions, a set of pressure relief equations were also incorporated into the dynamic reactor model. Therefore, the extended reactor model is able to calculate the relief pressure besides other variables in the reactors such as temperature, slurry density and solid hold-up, which provides an important guidance for selecting pressure relief device and safe production. Dynamic data from certain industrial reactor were used to verify the above model. Finally, the application of the extended model was demonstrated by simulating several typical emergency accidents.
The Costs of GM and Non-GM Co-existence in Processed Food Systems – Demonstrated for the Cases of the German Supply Chains of Chocolate and Frozen Pizza
Authors: Gabriel Andreas , Menrad Klaus
Published: April 2014

In contrast to the increasing use of GM plants in agriculture worldwide, the acceptance of GM food is still low in the European Union. If GM food products were introduced in the EU, the German food industry would be confronted with increased efforts to separate GM and non-GM processing lines and it would have to perform compulsory quality management. This paper analyses the costs of co-existence for producers of frozen pizza and chocolate in Germany. In order to provide an idea of the general magnitude of these costs, an adaptive calculation model was developed, supported by qualitative information from expert interviews for both sectors. The case studies reveal that the possibilities of the companies are quite different in terms of size, infrastructure, and available resources to operate parallel production. Companies which already have sufficient existing facilities to run separated production lines might have the opportunity for specialisation and could manage a possible emerging GM market situation.
Use of complementary and alternative medical therapies (CAM) by patients attending a regional comprehensive cancer care centre
Authors: Wilkinson Jenny M. , Stevens Mark J.
Published: April 2014

Background: This study determined the prevalence, types, and attitudes towards complementary and alternative medicines (CAMs) and therapies in cancer patients actively undergoing conventional cancer treatment at a regional cancer centre.

Methods: Data were collected using a self-administered questionnaire provided to adult cancer patients attending a comprehensive cancer care centre in regional Australia over a 3-month period.

Results: A participation rate of 89% was recorded over the 3-month period with 285 of 320 cancer patients providing completed data. Mean age was 64 years and slightly more females responded (56%). CAM types used by patients were classified according to US National Centre for Complementary and Alternative Medicine (NCCAM) domains. Overall prevalence of CAM use was 49% (140/285). The NCCAM domains of biologically-based treatments (mainly herbal and vitamin/mineral supplements) and manipulative/body-based methods (chiropractic and massage) were the most popular. Most patients (61%) who used CAM prior to cancer diagnosis continued complementary practices afterwards, and 33% of participants became first-time CAM users only after diagnosis. CAM use appeared to be associated with high patient acceptance and satisfaction which was not related to either cancer diagnosis or prognosis. Patients who used CAM were mainly willing to disclose (77%) this practice to their conventional health care providers.

Conclusions: CAM use is prevalent in regional Australia. Collaborative integration of some CAM practices into conventional cancer care pathways (a process known as integrative oncology) is likely to have substantial patient support.

partial functional integrodifferential equations
Authors: Diop Mamadou Abdou , Ezzinbi Khalil , Lo Modou
Published: April 2014

The aim of this work is to study the existence, uniqueness and
exponential stability of mild solutions for some stochastic neutral
partial functional integrodifferential equations. We suppose that
the linear part has a resolvent operator in the sense given in
Grimmer [Transactions of the American Mathematical Society 273 (1982), 333–349]. The nonlinear part is assumed to be continuous
and lipschitzian with respect to the second argument. Firstly, we
study the existence of mild solutions. Secondly we give some results
on the exponential stability in mean square sense. An example is
provided to illustrate the results of this work.
Burner Rig for Small Particle Erosion Testing of Thermal Barrier Coatings
Authors: Miller Robert A. , Kuczmarski Maria A.
Published: April 2014

The development of a high-temperature laboratory test to evaluate the erosion resistance of new turbine-blade thermal barrier coatings (TBC) for aircraft gas turbine engines is described. The focus is on improvements to a previously reported design, specifically: (1) larger duct and nozzle diameters leading to a larger and more uniform wear pattern; (2) incorporation of a new auger-style feeder for precise feeding of fine particles at low flow rates; (3) an aperture after the duct to limit the erosive damage at the edges of button specimens; (4) bag filters for particle feed rate measurements. The results of both extensive computational fluid dynamics (CFD) modeling and experiments concentrating on laboratory specimens fabricated from turbine-blade superalloys were used to demonstrate the validity of the test results to meaningfully evaluate the performance of new coating compositions in representative erosive environments, and to help understand damage mechanisms under such conditions. Two specimen geometries were tested in the improved rig using Mach 0.5 jets: “teardrop” burner bar and button specimens. Both types of specimens had electron beam–physical vapor deposition (EB-PVD) prepared ceramic layers of either ZrO2-Y2O3 (7YSZ) or ZrO2-Y2O3-Gd2O3-Yb2O3 (ZYGdYb) applied over PtAl bond coats using various processing parameters or interface treatments. Specimen temperatures for this study were either 980 °C (1800 °F) or 1090 °C (2000 °F).
