A natural ventilation "calculator": The challenge of defining a representative 'performance sketch' in practice and research
Authors: Donn Michael , Bakshi Nilesh
Published: July 2021

Too often in architecture and engineering, the simplicity in early design of the apparent guarantees of HVAC equipment manufacturers wins out over the complexity of estimating the effectiveness of natural ventilation even in Net Zero Buildings. The reality is many people in offices and schools find themselves sitting at a fixed desk, in full direct sun, with the cold draft from the HVAC equipment guaranteeing that on average they are comfortable. The drawing of blinds 'solves' the immediate sun problem, but not the quality of the air. Experience with 200+ students designing low energy, high performance naturally ventilated spaces each year over the past decade has demonstrated that the formulae that exist in the literature for early estimation of window opening size have potential if presented in an appropriate format to facilitate sound design decisions. This paper reports the evolution of that format to a calculation dashboard that facilitates accounting for: outdoor and indoor CO2 levels; wind speeds and frequencies of occurrence; coincidence of periods of calm with high outdoor temperatures; window effectiveness coefficients; single-sided vs cross-ventilation options; building shape and orientation; code minimum ventilation rates; and even infiltration. The paper focuses on the limitations of the approach and its potential complementary role in the future as a Quality Assurance tool for critiquing the output of CFD studies of natural ventilation.
The Effect of Macroscopic and Microscopic Patterns of Stainless Steel Surface on the Efficiency of Dropwise Condensation and Precipitation

Published: July 2021

Atmospheric water generator (AWG) technologies are considered a potential new source of freshwater. Thermoelectric (TEC) dehumidifiers are one of this technology where it uses the Peltier effect to create a heat flux at the junction of two different materials. This device is well known for its thermoelectric cooling application, from as small as portable beverage coolers to as big as submarines. The problems of using this device are ice buildup and relatively low efficiency. If the surface of the material can be engineered in a way that the dropwise condensation, as well as precipitation from the cooling plate, is enhanced, it is possible to maximize the efficiency of TEC-driven AWG with minimum energy consumption. This study investigates the effects of macroscopic (bump/dent, patterns that are visible to the human eye) and microscopic patterns (surface finish, quality, grain distribution, etc. visible under a microscope) on industry-grade stainless (SS) surfaces on dropwise condensation and precipitation. The surface contact angle is considered here to understand the hydrophobic/hydrophilic properties of the surfaces before and after applying hydrophobic coating under constant ambient conditions. Better droplet nucleation and quicker precipitation have been observed on the surfaces after treating a hydrophilic and hydrophobic surface with hydrophobic spray. It can be inferred that even though the initial surface property of the two samples were different, it was possible to achieve similar level of super hydrophobicity after applying the spray. This proves that surfaces can be modified with appropriate treatment to achieve desired properties.

By virtue of high-strength verses weight ratio aluminium alloys are achieving attentions in automobile, marine, and aircraft industries as it reduces the fuel consumption for running the vehicles. But their main drawback is the destruction of their carefully engineered microstructures by high heat generated in traditional welding processes. Friction Stir Welding (FSW) minimizes excessive heat in the welding zone and does not   influence the microstructural features.  FSW is currently one of the recommended solutions for manufacturing aluminium alloy welded machine parts. In this study, AA6061 Al-alloy strips were lap joined using the improvised FSW setup tool clamping it on the spindle of a CNC milling machine with the speed rate varied from 1000 rpm to 3000 rpm, and three different feed rates 5, 15, and 25 mm/min. Shear strength experiments of these joints revealed that samples created with the speed rate of 1000 rpm and feed rate of 25 mm/min performed best showing the highest load carrying capacity of 8976 N with elongation of 1.04%. They also demonstrated highest Vickers hardness value of 31 at the centre of the weldment.

Published: July 2021

Micromachining allows the production of parts and components on a micro scale with high precision and has become a key process to meet the growing demand for micro parts and micro components. To meet the quality requirements of the generated surfaces and reduce the cutting forces, strategies have been analysed, such as the use of the cutting fluid. Therefore, this research aimed to verify the effect of the frequency of the use of cutting fluid during the micro-milling of the Inconel 718 alloy. For this purpose, an ultra-refined cemented carbide micro end mill coated with (Al, Ti) N and 400 µm in diameter was used. A spindle speed of 20,000 rpm, a cutting speed of 13.8 m/min, a feed per tooth of 5 µm/tooth and an axial depth of cut of 40 µm were used as cutting parameters. Two frequencies of application of the cutting fluid were evaluated, corresponding to the flow rate of 40.7 and 270.0 ml/ h, in addition to the dry test. To measure the cutting forces, a Kistler dynamometer with operating range of -5 kN to +10 kN was used. In addition, the process simulation was performed using the AdvantEdge software by ThirdWave Systems. The results showed that the higher flow of the cutting fluid provided lower cutting forces and that, in dry machining, the cutting force increased significantly during the machining of a slot.

Published: July 2021

This study explores the application of Electron-Beam Welding (EBW) for joining Laser Powder-Bed-Fused Inconel 718 (L-PBF IN718) superalloy. Three different levels of electron beam speed and beam current were explored to give nine different electron beam heat inputs for experimentation. To define the weld characteristics microhardness, tensile, and fractography analysis using scanning electron microscopy, optical microscopy, and energy dispersive spectroscopy were conducted. Typical nail-shaped weld geometry was observed with penetration depth proportional to heat input. Most welded samples exceeded the yield strength (600MPa) and tensile strength (920MPa) requirements from the ASTM F3055 specifications for additively manufactured IN718, however, the specimens did not meet the ductility requirements (27%). Brittleness of the weld was attributed to the presence of brittle secondary phases in the weld matrix, and unfused metal powder of adjacent L-PBF layers. Post-processing heat treatments were recommended to improve the weld quality while improving the ductility of EBW joints.

حصار دولة قطر من منظور القانون الدولي ودور الوساطة في حلها – في ضوء المواقف العربية والإقليمية والدولية
Authors: السعدي منصور
Published: July 2021

يعد حصار قطر مشكلة مختلفة بإجراءاتها وأسبابها ودوافعها وتطوراتها؛ حيث لم يسبق أن شهد مجلس التعاون مشكلات مماثلة. وقد استند الحصار إلى ثلاثة افتراضات أساسية، وهي؛ الدعم الأمريكي، بقيادة الرئيس دونالد ترامب. ودعم الرأي العام المحلي. وقدرة الضغط القوي والمفاجئ على تغيير سلوك الدوحة بالقوة. ويمكن أن نؤكد أن سلوك دول الحصار مناقض للقوانين والمواثيق الدولية، على عكس مواقف الدوحة التي تمارس حقها في الحماية الدبلوماسية لمواطنيها. وقد كانت المواقف الإقليمية والعربية والدولية – باستثناء دول الحصار – مؤيدة لقطر، كما كان لاستجابة قطر السريعة في استيعاب واحتواء آثار الحصار الناجم عن الأزمة أثر كبير في تغيير تصورات دول الحصار عن إمكانية حل الأزمة كرهًا، أو طوعًا. وتتمثل إشكالية الدراسة في تحديد طبيعة، وأهمية، وجدوى جهود الوساطة، في ضوء المواقف المختلفة التي تبنتها الدول مع بيان آثار الحصار على واقع، ومستقبل مجلس التعاون في ضوء آفاق الحل المستقبلي.

The Right to Self-Determination of Modern Secessionist Movements under International Law
Authors: Al Sabbagh Ja’far Mohammad Khair
Published: July 2021

States’ boundaries have changed to a large extent over the course of time, in fact, the world has not always been the same as nowadays. In place of archaic forms of social organisation, the universal order has appeared where determinate and inviolable borders play a crucial role in ensuring the stability of states and resisting separatist movements. At the same time, secessionist movements throughout the world continually aim to gain independence from the ‘parent’ state invoking the right to self-determination. In this paper, the researcher will examine whether a part of the population of a state or a sub-unit of that state has a right to secede and create a new state and/or integrate into another. The article consists of a strong theoretical part dealing with statehood, self-determination and secession with a view of the dynamic development of these notions since the rapid birth of many new states as a result of decolonization. Thereafter, the validity of the gathered results will be verified by a comparative analysis of the cases of Kosovo, Crimea and Catalonia with regard to the historical background of these secessionist entities.

Published: July 2021

The aim of the work is to assess the influence of the method for preparing on the porosity of sintered polytetrafluoroethylene blanks as well as PTFE mixtures with carbon fiber and additives of powdered graphite. The article provides a comparative analysis of the method for preparing influence on the microporosity of sintered blanks made of filled and unfilled polytetrafluoroethylene. Microporosity has been determined through the comparison of the actual and theoretical (for a non-porous material) density of blanks, calculated by the methods of structural mechanics of composites. The studies made it possible to establish that the porosity of the unfilled polytetrafluoroethylene blanks pressed at a pressure of 70…80 MPa stands at 1.3 to 5.9 %. An exception was a specimen obtained by sintering in a jig, which has reached apparent density 2200 kg/m3 equal to theoretical density. It has been established, that the porosity of blanks obtained from polytetrafluoroethylene filled with shredded carbon fiber and powdered graphite stood at 0.4 to 3.9 %. An exception was a specimen with a high mass content of filler (40 %), in which the porosity was 16 %. It has been ascertained that sintering in a constrained state helps to reduce the residual microporosity for both the filled and unfilled polytetrafluoroethylene. This shows the technical efficiency of sintering in a constrained state, despite the increased labor intensity of the manufacturing process and the sophistication of technical equipment.

Published: July 2021

The study aimed to examine the levels of aggression and violence of students and other professional groups who are Düzcespor football fans. For the research model, the survey model, one of the quantitative research types, was chosen. The study's data collection process was carried out during the 2019-2020 season of the Turkey Football Federation, and the population of the study consisted of Düzcespor fans between the ages of 12-68. The sample of the study, on the other hand, consists of 498 people who voluntarily participated in the study using the random sample selection technique. As a result of normality tests (Kolmogorov-Smirnov and Shapiro Wilk), it was determined that the scores obtained from the scales did not show a normal distribution. For this reason, non-parametric tests Mann Whitney-U Test, Kruskal Wallis Test, and Bonferroni Test, one of the Post Hoc tests, were used to determine which group caused the significant difference between the groups as a result of the analysis. Frequency, percentage, minimum, maximum, average, and standard deviation values were also used to analyze the data. The level of significance was determined as p < 0.05. The study's findings showed that Düzcespor supporters had moderate aggression and violent behaviors. There was a significant difference between the variables of gender, age, education level, occupation and income, and aggression and violent behavior. The study results revealed that aggression and tendency to violence are higher in males, younger people, high school students and people with low income.
Tropical Purgatory: Brazil Through the Lenses of Stefan Zweig and Elizabeth Bishop
Authors: Camarneiro Fabio
Published: July 2021

Writers Stefan Zweig and Elizabeth Bishop both lived in Brazil, although in very different circumstances. Their stories served as basis for two films: Maria Schrader’s Stefan Zweig: Farewell to Europe (Vor der Morgenröte, 2016), and Bruno Barreto’s Reaching for the Moon (Flores raras, 2013). This article aims to describe the differences between these two films, and how they can be connected to Brazilian authors such as Gilberto Freyre and Sérgio Buarque de Holanda, whose works attempt to understand Brazil’s social dynamics from the perspective of its violent colonial past. Furthermore, this article aims to question the connections between historical accuracy and political engagement, arguing that the general tone of a film narrative may sometimes be much more politically-oriented than the actual facts it portrays.
Flowing Bodies: Autoethnographies of Desire in "Christmas on Earth", "Fuses" and "Je, tu, il, elle"
Authors: Moreno Pellejero Ariadna
Published: July 2021

This article explores how three women filmmakers express their ways of understanding and experiencing pleasure, based on a comparative study of Christmas on Earth (Barbara Rubin, 1963), Fuses (Carolee Schneemann, 1964–67) and Je, tu, il, elle (Chantal Akerman, 1974). By filming the subculture to which they belong or presenting themselves in the sexual act in a way that emulates ritual, these filmmakers recognize their own sexuality in opposition to the model that relegates the woman to the role of muse. Drawing on Artaud’s concept of ritual and his “Body without Organs,” this analysis posits the possibility of the concept of “flowing bodies,” referring to bodies in motion that affirm their own pleasure, andproposes to describe the three films explored here as “autoethnographies of desire.”

How success breeds success
Authors: Descamps Ambroise , Ke Changxia , Page Lionel
Published: July 2021

We investigate if, and why, an initial success can trigger a string of successes. Using random variations in success in a real-effort laboratory experiment, we cleanly identify the causal effect of an early success in a competition. We confirm that an early success indeed leads to increased chances of a later success. By alternatively eliminating strategic features of the competition, we turn on and off possible mechanisms driving the effect of an early success. Standard models of dynamic contest predict a strategic effect due to asymmetric incentives between initial winners and losers. Surprisingly, we find no evidence that they can explain the positive effect of winning. Instead, we find that the effect of winning seems driven by an information revelation effect, whereby players update their beliefs about their relative strength after experiencing an initial success.
