Heathrow Airport Terminal 2B, Phase 2 – a new pier facility constructed in an operational airside environment
Authors: Podesta Dean
Published: October 2023

With London's Heathrow Airport recently celebrating its 70th year of commercial operation and looking forward to further expansion, this paper describes a major contribution to its passenger handling infrastructure. As part of the redevelopment of the eastern side of Heathrow Airport, destined to become the new Terminal 2 (The Queen's Terminal), Mott MacDonald was appointed to deliver the civil and structural engineering scheme and detailed design for an operationally complex pier, intended to serve 10M passengers a year. The new pier was delivered on a physically constricted site inside the high-security (airside) zone of this major international airport. Building in such a location creates a singular set of conflicting demands, headed by the need to minimise the risks to aircraft operations through carefully planned and executed construction operations that avoid potential security breaches or alarms. This manifests itself in increased logistical challenges, including the need to security screen all staff, plant and materials entering the construction site, manage the execution of major construction works next to passenger aircraft operations, and overcome the effects of aircraft noise on safe working practices. These exacting circumstances demanded an equally singular design approach, focused on the use of appropriate, dependable, on-site construction methods and maximising off-site fabrication. All this was to be achieved while working with the architect to create a passenger experience consistent with a leading international hub airport.

The Evolution of LC Troubleshooting: Degassing
Authors: Stoll Dwight R.
Published: October 2023

As chromatography technologies change, our approaches to using them in ways that value reliability, as well as the ways we should approach troubleshooting and fixing problems, should also change. In this installment, I continue the discussion started last month about how some specific troubleshooting topics have evolved over time, this time focusing on mobile phase degassing. Understanding how approaches to degassing have evolved is helpful for troubleshooting problems with pumps and detection, designing reliability into new methods, and when considering updates to legacy methods that have been in use for decades.

Authors: Dzhindzhikhadze Revaz , Kambiev Renat , Polyakov Andrey , Zaitsev Andrey , Ermolaev Anton , Bogdanovich Igor
Published: October 2023

The choice of an effective and safe surgical approach is an important and largely outcome-determining step in the microsurgical treatment of cerebral aneurysms. Transcranial approach to aneurysm should provide proximal and distal control, visualization of the aneurysm and surrounding structures, freedom to work with microinstruments, optimal and close view of the surgical field with the necessary ergonomics and the possibility of comfortable work for the neurosurgeon. In addition, the approach should provide a low risk of associated complications, good cosmetic outcomes and patient satisfaction. Today, a neurosurgeon has a sufficient number of approaches to cerebral aneurysms. Minimally invasive approaches are the reduced model of traditional approaches and each of these approaches has a specific surgical corridor that cannot be changed during microsurgical manipulations, unless through the transition to an extended craniotomy.
Numerical Simulation of Icing Characteristics on a Blade Airfoil for Vertical-Axis Wind Turbine under Various Icing Conditions
Authors: Xu Zhi
Published: October 2023

The phenomenon of icing on wind turbines gives rise to significant liability concerns in regions characterized by cold and humid climates, especially those with extreme climatic conditions. Accordingly, investigating the icing characteristics is essential for the safety operation of wind turbines. In this chapter, an icing model coupling water film flow with water film evaporation considering airfoil surface roughness is developed to investigate the effect of icing conditions on the icing characteristics of a blade airfoil for vertical-axis wind turbines by numerical simulation. The mechanism of heat and mass transfer under various icing conditions is explored. The results show that the simulated and experimental ice shapes on the airfoil agree well. The ice shape contour fluctuates along the airfoil surface at higher ambient temperature due to water film flow and heat flux variation. A large area of airfoil surface is covered by ice accretion at high wind speed due to an increase in driving force acting on water film and convective cooling between water film and air. The maximum ice thickness changes more significantly at wind speeds of 2–7 m/s than that at wind speeds of 7–12 m/s. This contributes to theoretical basis for exploring anti/de-icing method in wind turbines.

Published: October 2023

Background: Toxoplasma gondii is the most common intracellular parasite in the human population. The anti-cancer effect of these parasites has been shown, which may be due to the presence of common antigens between the parasite and cancer cells. Objectives: In this work, the reaction of Toxoplasma-positive human sera and Toxoplasma-negative human sera with cell surfaces of 4T1 and MCF7 cell lines have been investigated. Methods: 4T1 and MCF7 cells were harvested from cell cultures and treated with either human Toxoplasma Positive or negative sera. The reaction of the sera was then detected using the flow cytometry method. Results: Toxoplasma-positive sera reacted more strongly with both breast cancer cell lines than Toxoplasma-negative sera. Conclusions: Anti-T. gondii antibodies strongly react with breast cancer cells. These antibodies may be used for selective cancer immunotherapy in the future.

Published: October 2023

Background: Management of common and unpleasant complications following the removal of the arterial sheath is one of the goals and priorities of nursing care in patients undergoing angiography. Objectives: This study aimed to design and manufacture a FemoStop device and compare its effectiveness with sandbag pressure on hemostasis during sheath removal and reducing puncture site complications following transfemoral coronary angiography. Methods: This randomized controlled trial was conducted between 2019 and 2021. Eighty patients undergoing elective transfemoral coronary angiography referred to a Heart and Vascular Hospital in Tehran were recruited by convenience sampling and were randomly assigned to experimental (n = 40) and control (n = 40) groups. FemoStop devices and sandbags were used in the experimental and control groups to control angiography complications, respectively. The patient’s individual characteristics questionnaire, visual analog scale, checklist of complications, and laboratory indicators were used for data collection. Pain intensity, heart rate, respiratory rate, temperature, systolic and diastolic blood pressure, arterial oxygen saturation, and the amount of hematoma and bleeding of patients before, after 15 minutes, 1 h, 2 h, 2.5 h, 3 h, 3.5 h, 4 h, 4.5 h, 5 h, and 6 h were measured after the intervention. Results: The trend of changes in pain intensity (P < 0.001), heart rate (P = 0.036), and systolic blood pressure (P < 0.001) of patients in the experimental and control groups after the intervention was significant, and in patients who had used the FemoStop device, it was less than the control group. However, the changes in respiratory rate (P = 0.308), diastolic blood pressure (P = 0.089), arterial oxygen saturation (P = 0.205), and temperature (P = 0.195) of patients in the 2 groups were not significant. The 2 groups were not significantly different in terms of these variables and the amount of hematoma and bleeding in the 12 stages of measurement. Conclusions: Compared to using a sandbag after transfemoral coronary angiography, the FemoStop device leads to fewer complications, such as pain intensity, lower heart rate, and systolic blood pressure in patients. Therefore, considering fewer complications, it is suggested to conduct more studies to confirm the use of this device to control complications in patients.

Authors: Farhadi Khosro , Rahimi Mehdi , Shahmohammadi Afshar
Published: October 2023

Background: Urinary tract infection (UTI) is the highest incidence of hospital-acquired infection (HAI), and hospital-acquired urinary tract infections (HAUTI) are a common problem of critical illness. Objectives: This study aimed to determine the epidemiology of HAUTIs in medical intensive care units (ICUs) and hospitals in Kermanshah, Iran. Methods: This cross-sectional and descriptive/analytical study was conducted in the ICUs of hospitals in Kermanshah from March 2018 to 2019. All the recognized HAUTIs were recorded in the Iranian National Nosocomial Infection Surveillance System. Descriptive and inferential statistics such as t-tests and chi-square were used for data interpretation. Results: A total of 1136 patients were admitted to the two ICUs (61 missed out of 1197 patients). The number of patients with UTI was 51, and the overall HAI rate was 4.5%. The results showed a significant relationship between sex and HAUTI (P = 0.038), so women tended to have more HAUTIs than men (6.3 and 3.6%, respectively). A significant relationship was observed between age, date (different seasons of the year), and HAUTI (P = 0.588, 0.115, respectively). Conclusions: There are few studies on HAUTIs, especially on intensive care unit-acquired infections, and more studies are required to describe the epidemiology and management of these problems. Improving conditions for expanding any strategy to reduce infections associated with HAUTIs in ICUs is recommended.

Design and fabrication of functionalized high porous poly(lactic acid)-based scaffolds for tissue engineering
Authors:   , Puñet Ortiz Xavier
Published: October 2023

Intelligent scaffolds are designed to trigger the healing regeneration process through the controlled released or disposition of bioactive signals. The fabrication of intelligent scaffolds needs the development of novel techniques able to introduce biomimetic properties on the final product through easy and scalable techniques. This thesis is focused on the characterization and development of two versatile techniques for the fabrication of intelligent scaffolds. The first technique is based on the biofunctionalization of polymeric surfaces with synthetic polypeptides (elastin-like recombinamers) for the improvement of cell-surface interactions. The second technique is based on the fabrication of highly porous poly(lactic) acid scaffolds with a nano-fibrous structure that resembles the natural extracellular matrix by means of a novel non-toxic, cheap and easy process.

Los andamios inteligentes son diseñados para activar los procesos de regeneración a través de la dosificación o disposición controlada de señales bioactivas. Sin embargo es necesario desarrollar nuevas técnicas capaces de introducir propiedades biomemiméticas en dichos andamios a través de metodologías sencillas e industrializables. La presente tesis se centra en la caracterización y desarrollo de dos técnicas versátiles para la fabricación de andamios inteligentes. La primera técnica se basa en la biofuncionalización de superficies poliméricas con polipéptidos sintéticos (elastin-like recombinamers) para la mejora de las interacciones entre las células y la superficie del material. La segunda técnica se basa en la fabricación de andamios de ácido poli(láctico) altamente porosos, con una estructura nano-fibrosa que mimetiza la matriz extracelular, a través de procesos fáciles, económicos y no tóxicos.
Influencia de las tensiones residuales de mecanizado en las propiedades mecánicas de Y-TZP
Authors:   , Juy Aguirre Alberto
Published: October 2023

En esta tesis se han desarrollado microestructuras mediante tratamientos térmicos de 2,5Y-TZP, las cuales con la adición de tensiones residuales de mecanizado, experimentan un aumento de la resistencia y la tenacidad de fractura. La microestructura con mejores propiedades se obtuvo para la temperatura de 1650 C con un tiempo de permanencia de 40 minutos (40M), y está compuesta por granos tetragonales y granos compuestos por precipitados tetragonales y matriz de fase cúbica. El crecimiento del grano tetragonal produce el aumento de la transformabilidad y un consecuente incremento de la tenacidad. La resistencia a la fractura aumenta, pero si el grano tetragonal es mayor de 1 m disminuye ligeramente debido a que los defectos que originan la fractura aumentan más que la tenacidad.

Los procesos de mecanizado estudiados inducen tensiones residuales de compresión en la superficie, lo que ocasiona el aumento de la resistencia y la tenacidad de fractura. La transformación de fase de tetragonal a monoclínico sólo se produce durante el rectificado del material tratado durante 10 horas (mayor transformabilidad). El proceso de desbaste plano no ocasiona la transformación de la fase tetragonal en los materiales analizados, sin embargo produce la transformación de fase de monoclínico a tetragonal.

Las tensiones residuales de mecanizado aumentan la resistencia al daño por contacto, porque disminuye el daño cuasiplástico subsuperficial, y no se forma daño alrededor de la zona de contacto en las muestras ensayadas a fatiga de contacto.

Las tensiones residuales aumentan la resistencia al choque térmico. Los resultados demuestran que no se produce agrietamiento, ni transformación de fase bajo estas condiciones de ensayo. Las tensiones residuales no disminuyen durante el choque térmico, y se oponen a la propagación de la fisuras de indentación, manteniéndose además las propiedades mecánicas.

Published: October 2023

Se revisan los antecedentes y el estado del arte en la conformación de aleaciones de aluminio en estado semisólido. Se describen los diferentes procesos, sus ventajas e inconvenientes y su interés industrial de acuerdo con la información disponible. Se plantean los aspectos teóricos de la conformación en estado semisólido relacionados con: las propiedades tixotrópicas y reológicas de los materiales; los mecanismos de formación de lodos; la estructura de los lingotes; y los efectos del recalentamiento y de los tratamientos térmicos.

Mediante técnicas de Thixocasting se han fabricado, con aleaciones A357 y A356, diferentes piezas: lingote, semicomponente y componentes para automóvil y motocicleta. En estos materiales se estudia el efecto de los tratamientos térmicos en la microestructura, en las propiedades mecánicas y en los mecanismos de fractura.

La experimentación realizada permite determinar el efecto de la temperatura en: la velocidad y mecanismo de crecimiento del silicio; la evolución de la fase  y los compuestos intermetálicos; y en la distribución más o menos heterogénea del magnesio.

Así mismo, la producción de semicomponentes en diferentes condiciones, mediante un exhaustivo control de las condiciones de fabricación, ha permitido optimizar los parámetros de producción mediante procedimientos estadísticos.

Se estudian los mecanismos de corrosión en soluciones salinas en los diferentes materiales, mediante ensayos en cámara de niebla salina, medidas de impedancia y técnicas de polarización.

Finalmente se realiza un estudio comparativo de los resultados obtenidos con componentes fabricados por Thixocasting, por otros procesos de conformación en estado semisólido (New Rheocasting y Sub Liquidus Casting) y por los métodos convencionales, poniendo de manifiesto las ventajas e inconvenientes de las nuevas tecnologías.
Caracteritzación dinámica de dos aceros microaleados de medio carbono mediante ensayos de compresión a alta temperatura Aplicación de mapas de procesado
Authors:   , Al Omar Mesnaoui Anas
Published: October 2023

La presente tesis se centra en la caracterización de dos aceros microaleados de medio carbono, con composición química diferente, mediante ensayos de comprensión en caliente a velocidades de deformación verdadera constante. Por ello, se estudia las características de fluencia y el comportamiento de recristilización dinámica de los dos aceros a diferentes temperaturas y velocidades de deformación. Asimismo se ha analizado el efecto de la precipitación dinámica y la interacción entre la recristalización y la precipitación dinámica.

Usando el modelo dinámico de materiales se optimizan, en este estudio, los parámetros del proceso de deformación mediante los mapas de procesado de cada acero, a diferentes condiciones de austenizacion. Los resultados obtenidos muestran que los mapas de deformación exhiben varios dominios asociados a los fenómenos de restauración y recristalización dinámica. Además se verifica que la estructura inicial tiene un efecto muy importante en la evolución de los mapas de procesado y el comportamiento a fluencia de ambos aceros.

También se comprueba que el comportamiento a fluencia en caliente de ambos aceros estudiados puede ser correctamente modelizado con la ecuación clásica del senohiperbolico teniendo en cuenta la normalización de la tensión por el modulo de young y de la velocidad de deformación por el coeficiente de autodifusion de la ustenita d(t). Además, se verifica que para mantener la validez del modelo utilizado es necesario incluir una tensión adicional a la tensión global cuando el tamaño de grano inicial es muy fino.
Aproximación al estudio del riesgo del bleve y sus efectos en los generadores marinos de vapor y los tanques de carga de los buques LNG-LPG. Aplicación comparativa de las normas que lo regulan y previenen

Published: October 2023

BELEVE son las iniciales de la siguiente expresión inglesa "Boiling Liquid Expanding Vapor Explosion" que traducido librementes ignifica "Explosión de los Vapores que se expanden al hervir un líquido".
La ELEVE es comúnmente definida como la ruptura en varios pedazos de un recipiente, con proyección a grandes distancias, superiores a las que las desplazarían la simple energía de un estallido, que se da en determinadas circunstancias, siendo necesario, pero no suficiente, que el líquido contenido en el recipiente, posea una temperatura superior a la que le correspondería tener si estuviera a la presión atmosférica normal.
Por tanto, la temperatura de ebullición debe ser bastante menor que la temperatura a la que se encuentre la masa líquida en el recipiente, es decir, lo que se llama o denomina líquido sobrecalentado.
El fenómeno ELEVE es una manifestación exclusiva de los líquidos sobrecalentados, no debiéndose confundir con las explosiones que se producen en los recipientes que solamente contienen gas, pues las energías desarrolladas por la explosión de este último, no son en absoluto comparables a las elevadas del fenómeno ELEVE.
En el caso de que el fenómeno ELEVE se manifieste en un recipiente que contiene líquido que es químicamente reactivo o combustible, agrava el problema de la ELEVE propiamente dicho, ya que anteriormente se ha indicado que un ELEVE se puede producir en una caldera de vapor de agua.

Published: October 2023

Pandemi covid yang terjadi selama lebih dari dua tahun telah berdampak pada kondisi psikologis masyarakat Indonesia. Penerapan kebijakan lockdown telah membatasi aktivitas fisik seseorang untuk beraktivitas di luar ruangan dan memaksa seseorang untuk beraktivitas di dalam rumah. Hal ini mengakibatkan banyak orang mengalami stres selama lockdown. Yang paling rentan stres dan paling sulit mengendalikan stres adalah anak-anak. Hal ini terjadi karena anak belum mampu mengendalikan emosinya dengan baik dan belum mengetahui apa yang sebenarnya terjadi. Dengan melihat kondisi anak pasca pandemi, diperlukan program untuk mengatasi kondisi stres yang terjadi pada anak. Salah satu alternatif yang cukup efektif untuk membantu mengatasi stres adalah terapi bermain. Berangkat dari keresahan yang nyata ini, Pengabdian Masyarakat (PKM) di MI Muhammadiyah Klopogodo, Kecamatan Gombong, Kabupaten Kebumen. Penerapan terapi bermain dilakukan dalam beberapa tahap. Tahap awal yang dilakukan untuk memulihkan stres yang dialami siswa adalah bercerita. Dengan mendongeng, diharapkan tingkat stres dapat dikurangi. Tahapan selanjutnya adalah bermain dan belajar dengan menggunakan metode Play Therapy. Pelaksanaan terapi bermain dilakukan oleh profesional atau pihak yang berkompeten di bidangnya. Dengan adanya layanan ini, stres pascapandemi yang dialami mahasiswa dapat diminimalisir bahkan dinetralisir.
الصراع الفكري بين الاحزاب الحاكمة والاخوان المسلمين واثره في فشل التحول نحو الديمقراطية الغربية: (نماذج مختارة)
Authors: Hasan Hadi Rasheed
Published: October 2023

علمنا التاريخ ان التحول الفكري للأنظمة السياسية غالبا ما يكون من خلال التغيير الثوري المباشر، ولكننا شهدنا خلال العقود الاخيرة  تغير يبدا على شكل ثورة او احتجاج، ولكنه لا يحصل فيه تغير بشكل مباشر للنظام. وهذا يعود لأسباب عديدة منها خلل في منهاج وقدرة القائمين على الثورة، واما السبب الاخر محاولة النظام القائم الهرب نحو الامام عبر اشراك اكبر عدد ممكن من المعارضين له بالمشاركة في العملية السياسية، وفي نتيجة توصلنا لها من خلال الاطلاع على بعض التجارب ان هذا الهروب كان له نتائج سلبية. لان اصحاب هذه التجربة لم تكن لهم قراءة حقيقية لهذه القوى، وايضا لجهلهم حقيقة موقف الشعب منهم، معتمدين على موقف الشعب وهو في حال الاضطهاد والانكسار، غير مستدركين انه في حال فسح له المجال سوف يختار غيرهم وان كان شرا منهم، فتحدث صدمة متبادلة للأحزاب الحاكمة، وللقوى الصاعدة الفائزة بعدم قدرتها على القيادة والسير نحو بر الامان في ظل التحديات التي واجهتها، وامام التخبط والخطوات غير المدروسة من القائمين على الثورة او الاحتجاج فضلا عن الحزب الحاكم، وكذلك فشل خيارات الشعب المبنية على البحث عن بديل ايً كان شكله، لذلك كانت النهاية كما في هذه التجارب التي مر بها عالمنا العربي هي الحرب الاهلية بين الفريقين وانهيار العملية السياسية، بعد ان يكون الشعب هو الضحية الاكبر.

A Right Response to Anti-Natalism
Authors: Liao S. Matthew ,   Saint Louis University
Published: October 2023

Most people think that, other things being equal, you are at liberty to decide for yourself whether to have children. However, there are some people, aptly called anti-natalists, who believe that it is always morally wrong to have children. Anti-natalists are attracted to at least two types of arguments. According to the Positives Are Irrelevant Argument, unless a life contains no negative things at all, it is irrelevant that life also contains positive things. According to the Positives Are Insufficient Argument, while life does contain some positive things, as a matter of fact, almost everyone’s life contains more negative things than positive things. In this article, I first offer new reasons to reject these arguments. I then offer a positive, human rights account of why not only is it not wrong to bring people into existence, but parents in fact have a human right to do so.

Analiza transferu ryzyka ekstremalnego między wybranymi rynkami finansowymi z zastosowaniem przyczynowości w ryzyku w sensie Grangera
Authors: Fałdziński Marcin
Published: October 2023

The main aim of this paper is an analysis of integration among main financial markets which represent financial and economic processes occurring in the contemporary world. This research focuses on issue of extreme risk spillover effect on financial markets. Proper understanding of risk transfer mechanism has paramount importance for effective risk management, financial institutions and market supervision institutions. In particular, extreme risk is the most important due the fact that the extreme prices movements are the main cause of threats and opportunities for market participants. This paper is the extension of previous researches on that issue. This extension takes into account the newest methodology framework which is Granger-causality test presented in work of Candelon et al. (2013). Innovation in this approach boils down to allowing for multiple different risk levels across distribution tails which takes into consideration different dynamics of risk transfer mechanism across markets. In order to estimate Value-at-Risk a Peaks over Threshold approach is applied with volatility models (McNeil, Frey, 2000).
Zmiany wartości polskiego eksportu w ujęciu Trade in Value Added na tle krajów Grupy Wyszehradzkiej
Authors: Nowicki Michał
Published: October 2023

Research on export based on domestic value added greatly complements the knowledge about the gross export of a given country. This measure provides not only information on trade flows, but also makes it possible to determine how much they are the result of work carried out in a given country and to what extent they depend on other links of value chains. The Trade in Value Added (TiVA) database, created by OECD and the WTO, provides such information. However, the data tend to be rarely analysed and presented in public discourse. The aim of the study presented in the paper is to show the changes in Polish export based on TiVA. In order to create a complete picture of the situation of Poland, the data covering TiVA for Poland were compared with analogous results obtained for the other Visegrad Group countries, whose economies share similar historical and geopolitical conditions: the Czech Republic, Slovakia and Hungary. The study uses data covering the period between 2004 (the year Poland joined the EU) and 2018 (the last year available in the database) and applies descriptive and statistical methods. The main hypothesis of the paper, stating that TiVA in Polish export grows relatively slower than the value of export measured in the traditional way, was verified. Additionally, a supporting hypothesis, assuming that TiVA in Polish export increases relatively slower than in the other researched countries, was also examined. The analysis shows that Poland has a significantly higher percentage of domestic value added in export and the dynamics of the changes in this factor is higher compared to the other Visegrad Group countries. Nevertheless, the growth rate of Polish gross export measured in the traditional way is higher than the export measured according to TiVA.
