Published: May 2021

Violence is a global phenomenon, and any contemporary society is not without this phenomenon, and the difference between societies in this phenomenon is in the degree of violence.Violence has many patterns, including some that takes behavioral activity, as it crystallizes according to what constitutes it on the one hand, and the nature of the social contexts from which it emerges and appears on the other hand. And with different social contexts, the patterns of the phenomena of thought violence may vary and vary.And that the practice of violence and whatever the actor in it, whether it is official, informal or popular violence, resorting to it indicates the existence of a crisis in society, the degree of its severity may be commensurate with the level of violence on the quantitative and qualitative levels. This study came (to know the trends of foreign satellite channels speaking in Arabic Regarding violence in Iraq) by analyzing the content of the study channels from Sky News and Al-Alam. In this study, the researcher aimed to achieve a set of objectives represented in identifying the nature of the trends adopted by Sky News Arabia and the Al-Alam channel in question, within each of the axes Violence in Iraq. And revealing the degree of relative focus that each channel in question has given to the axes on the issue of violence in Iraq. And to diagnose the trends of foreign Arabic-speaking satellite channels, represented by Sky News Arabia and Al-Alam TV, about violence in Iraq within all axes on the issue of violence. This study falls under the classification of descriptive research that depends on the content analysis form of the two study channels in terms of or content, by analyzing the content of news analyzes in the two channels during the period of the study. The research concluded with a set of results, the most important of which are: - The axis (the role of armed militias in spreading violence in Iraq) has won the first place in the hierarchical distribution of the axes of the main categories of analyzes in Sky News, after it obtained (34) recurrences and percentage A percentage of (38%), and this axis did not get any repeat in Al-Alam channel, and thus it ranked sixth and last in the channel. - The axis (neighboring countries and their role in the violence in Iraq) came in second place, with a number of (21) recurrences, and a percentage of (23.59%) in Sky News, while this axis ranked fifth with (10) recurrences and (9) %) On Al-Alam channel. - Axis (the Iraqi government and its position on the violence in Iraq), this axis came in third place with (16) recurrences, and a percentage of (17.97%) in Sky News. This axis ranked third also with (18) recurrences and a percentage (16.36%) in Al-Alam TV.

Harmonic distortion is one of the most important power quality issues in third rail electrification systems. The use of rectifiers and inverters in the third rail system can inject a significant amount of harmonic distortion to the electrical network. This paper aims to investigate the harmonic distortions for a DC urban third rail system at various operating conditions. The electrical network of Mass Rapid Transit Line 2 (MRT 2) Malaysia is modelled using ETAP software. The model had considered the effect of the inter-phase transformer in the 12-pulse rectifier. The current injection method is used to measure harmonic distortion at Point of Common Coupling (PCC) at the 132 kV and 33 kV buses. A normal and degraded operating conditions of power supply are investigated. From the simulation results, it is found that the 11th and 13th order harmonics have exceeded the statutory limit at 33 kV network for the normal operating condition. For the degraded operating condition, only the 11th harmonic order has exceeded the statutory limit. Keywords: Harmonic Distortion; DC Urban Rail; Various Operating Conditions

Based on the development of new technologies in the electrical engineering field, microgrids can be understood as the effective implantation of smart grids. These, in turn, have functionalities for energy management, such as voltage control, frequency, and demand management, and can also operate in a connected or island mode concerning the utilities resources. In the face of such technological advances and energy management, this paper presents a proposal for the implementation of a microgrid, called CampusGRID. This microgrid will be installed on the University Campus of UNICAMP - Brazil, being connected to a 11.9kV level voltage grid with 2370 kVA power rated shared among eleven points of connections and demand varying from 475 to 768 kW. For the control of loads (electric vehicle, classroom buildings, laboratories, libraries, convention center, multidisciplinary gymnasium), it is proposed to automate the circuits in the secondary side of transformers to control the loads, as well as the monitoring of these. For the power generation system, a set of distributed energy resources (DER) was considered, such as photovoltaic sources (PV), sources with cogeneration known for the combination of heat and power (CHP) using natural gas and storage system with lithium-ion batteries. These energy resources will be controlled by a centralized energy management system, with fiber-optic network communication, ensuring signal synchronism to the equipment for the provision of services, as well as serving as a means to collect the data set from the respective equipment for studies and performance improvements of the CampusGRID microgrid.

This Open urban space functions as the stage of the city where public life unfolds. These spaces, which provide traffic networks, communication nodes and common spaces for play and relaxation and play a key factor in shaping cities and enhancing urban resilience. Forming and planning urban spaces is a complex and demanding process and, in many cases, the final approved proposal lies upon city decision-makers. Supporting stakeholders to approve plans and regeneration actions creating desirable open spaces, corresponding to urban living needs, seems crucial. In this framework, the research focuses on identifying the priorities of the decision-making prosses and citizens’ preferences on open urban spaces. In addition, the way in which citizens’ preferences define the number of their visits to an urban space is investigated in order to develop a model estimating Demand side on open urban spaces. As the parameter of Supply of open urban areas should not be ignored in this process, the Visiting Index is developed as the key performance indicator to be under study by stakeholders. At last, considering that urban areas are complex, dynamic systems evolving rapidly, the dynamic relationships among the parameters of Visiting Index are described in Casula Loop Diagram to contribute to making open urban spaces effectively manageable.

Yorgos Photis was my spiritual son, my student, my advisee, my helper, my colleague, my friend, my confidant and regrettable the sack of box to relieve my anxieties and worries. He suddenly left this world to meet his maker, who I am certain will show His mercy on such a fine man. Once I read a father's eulogy for his son, which fits exactly how I feel about Yorgos "The sunflowers, the lilies and the lush green grass looked cheery, so long as you were around. Do you think they will ever look green again, once the meaning in life I have lost is found?" Yorgos I wished I had remembered that passage more often and mainly practiced it when you were around me! But I remember the first time I called you in my office, as a young professor who care about his students, trying to deciphered the unkind remarks of a fellow professor about you. I am so proud that you have proved him so wrong. We worked together and you finished your undergraduate thesis, your PhD, and you climbed all the academic grades. You followed my steps in a more successful manner and became a professor of Geographical Analysis and Locational Planning, a department head, associated editor of the European Journal of Geography, president of the Hellenic Geographical society, and member of the board of EUROGEO- the European Association of Geography. I want to declare that I will continue to show my feelings for you, so that I will talk about you because I am proud of you. I will talk about you, because you deserve to be remembered. I will talk about you, because even though you not physically with me, you are never from my mind. I will talk about you, because you are part of me, a part that I could never ignore or disown. I will talk about you because I love you still and always will. Nothing will ever change that. The passing of Yorgos Photis has been a great loss to his family, the university, the department and the lab he was serving, as well as the Hellenic Geographical society, the European Journal of Geography and EUROGEO he was committed to their advancements.

Bell's palsy is a peripheral facial palsy with high incidence, which has some associated factors such as pregnancy, diabetes mellitus and hypertension, in addition to infection by some subtypes of the herpes virus, i.e. herpes simplex and herpes zoster sine herpete. A common feature of patients with Bell's palsy is the occurrence of ipsilateral headache of periauricular location, days before the onset of the paralysis. It is questionable, therefore, whether it is possible to identify a characteristic pattern of this pain in order to prevent disease progression or mitigate the possible development of motor deficit by initiating appropriate and immediate treatment to suppress the inflammatory process of the facial nerve. We report the case of a 50-year-old man with facial palsy on the right side, with pain in the ipsilateral retroauricular. At the age of 15 he reported a previous episode of facial palsy, also on the right side, with severe retroauricular pain, similar to the current recurrence. We propose diagnostic criteria for the retroauricular headache associated with idiopathic peripheral facial palsy.
Initiation of Stress Corrosion Cracking in Cold-Drawn Prestressing Steel in Hardened Cement Mortar Exposed to Chlorides
Authors: Joseline Dyana , Pillai Radhakrishna G. , Neelakantan Lakshman
Published: May 2021

Cold-drawn, high-strength, prestressing (PS) steel strands are widely used in pretensioned concrete (PTC) structures. This paper discusses the stress corrosion cracking (SCC) of PS steel embedded in cement mortar and gradually exposed to chlorides. Various stages of the passive to active (P-to-A) transition, which marks the onset of SCC, were investigated using the electrochemical impedance spectroscopy technique. The key mechanisms were identified and confirmed using scanning electron microscopy/energy dispersive x-ray analysis, x-ray diffarction, and confocal Raman spectroscopy. It was found that the passive film on unstressed PS steel has better electrochemical characteristics than that on conventional steel rebars. However, the residual tensile stress at the surface of PS steels can assist passive film cracking after chloride attack—contrary to the pitting corrosion without cracking of passive film in conventional steels. Further, tests indicated that the concentration of chlorides required to crack the passive film in PS steels can reduce by about 50% when prestressed—as in field structures. Chemical composition, stress state, and microstructural features at the PS steel surface were identified as possible factors influencing the initiation of SCC in PTC structures.
Corrosion and Hydrogen Permeation in H2S Environments with O2 Contamination, Part 3: The Impact of Acetate-Buffered Test Solution Chemistry
Authors: Joshi Gaurav R. , Deffo Ayagou Martien Duvall , Mendibide C. , Mai Tran Thi Tuyet , Tribollet Bernard , Kittel Jean
Published: May 2021

This paper highlights the importance of considering the magnitude of acetate (ethanoate) species concentration on corrosion and hydrogen permeation rates, important factors associated with cracking initiation in steels for sour service qualification. Materials selection relies on standards, such as NACE TM0177 and NACE TM0284, which stipulate that oxygen pollution should be avoided during testing in H2S-containing media. The 5% NaCl test solutions in current standards are buffered using acetic acid (CH3COOH)/sodium acetate (CH3COONa) to fix the solution pH over long periods. In this third paper, as part of a series of articles that evaluate how oxygen entry modifies the corrosion of (and hydrogen permeation across) low alloy steel membranes in H2S-containing solutions, the effect that changing the solution chemistry has through testing X65 steel in different concentrations of acetic acid and sodium acetate in H2S-saturated 5% NaCl solutions, i.e., Solutions A and B (NACE TM0177-2016) and the high-strength line pipe (HLP) solution of NACE TM 0284-2016, is investigated. Increasing the total acetic acid + acetate concentration encourages a higher average X65 corrosion rate and longer-sustained hydrogen charging flux, assigned to the cathodic reaction rate enhancement by acetic acid and the iron solubilizing effects of acetates. Introducing 300 ppb of dissolved oxygen does not push the solution pH outside of the permitted error range but increases average X65 corrosion rates and, again, helps sustain hydrogen permeation flux for longer. Through an evaluation of the surface structure and electrochemical data, this appears to be due to an increase in the permeability and protectiveness of the troilite FeStroilite dominant scale and a possible acetic acid buffering of local pH increase at surface cathodic sites during corrosion. The HLP solution (at pH 3.5), with the highest acetic acid and acetate concentration, is the most aggressive. In this electrolyte, an iron sulfide overlayer structure is attained with an oxygen-rich inner layer between the metal substrate and a thick iron sulfide film.

Due to urbanization and industrialization huge amount of wastewater is being generated, which is causing water pollution. Nowadays water pollution is a serious problem. The present study has been carried out to evaluate the efficiency of a waste water treatment plants with Extended Aeration Sludge Process (EASP). This has been done by examining the various physiochemical characteristics of wastewater (BOD, COD, TSS & PO4), including a comparison of these characteristics at inlet and outlets of wastewater treatment plants and their variance over time. The examination of the competency of a technology is necessary for further optimization of the treatment units whilst complying with the Central Pollution Control Board (CPCB) requirements. In New Delhi’s Extended Aeration Plants are not working to their peak potential, but have still been able to treat the significant wastewater effectively. The study implies that the effluent released into the Yamuna River would not contribute to the river’s level of pollution.
Stigmatization of Fat Characters, a power play of Discourse and Hegemony: an Investigation in to the Truth

Though the fat person in the eighteenth and nineteenth century culture usually represented wealth and prosperity, or by extension, either literally or metaphorically, greed and avarice, there was one situation in which fat people themselves were mocked and shamed. Extremely fat people were seen as a form of human grotesquery. They serve as a spectacle of oddity in fairs, circuses, vaudeville and most recently on television programs such as ‘The Biggest Loser’. In all this the fat man suffers the greatest humiliation. His body is at once exposed and undignified. The negative effect that these freaks shows had on viewers who themselves were fat, or those who feared becoming fat, or certainly on those who were themselves the object of ridicule. The stigma in this case, however, is one of oddity and uniqueness. What is clear from the historical documents, however, is that the connotations of fatness and of the fat person- lazy, gluttonous, greedy, immoral, uncontrolled, stupid, ugly, lacking in will power, primitive- preceded and then intertwined with explicit concern about health issues. Fat bodies as Foucault would say, is considered as hegemonic knowledge or stereotypes which are enforced by the authorities. Thus body size and weight can be seen and explored as a set of social meanings. The desire to raise one’s social status is a key motivational force for dieting. Creation of hegemonic understanding of fatness as a problem and discursive and other practices that aim at determining normalcy can be justifiably seen along the lines Foucault’s notion of power and specifically those of Biopower and Biopolitics. According to Foucault these power works through discourses and hegemonic knowledge.
The impact of eThekwini municipality policies on informal traders: a case study of the northern regions of eThekwini
Authors:   , Ramsuraj Trisha
Published: May 2021

The informal economy contributes about 5.2% of the gross domestic product of South Africa. It is estimated that it employs more than 2.6 million people which represents about 10% of the total employment in the country. However, this is considered to be low if it is compared to other African countries, despite the high unemployment in the country. Therefore, there may be some constraints hindering the growth of the informal sector. The apartheid government that was in place before 1994 enacted laws and policies that hindered the growth of the sector. In recent times the South African government has been revising the laws and putting in place policies that encourage the growth of the informal economy. A number of studies have shown that eThekwini Municipality has one of the best policies which target the informal economy in South Africa. Some of the policies that have been launched include National Informal Business Upliftment Strategy at national level and Durban’s Informal Economy Policy. The current Integrated Development Plan for eThekwini Municipality has sections specially dedicated to the informal economy. Despite the efforts of the national, provincial and local governments, the policies have been failing to be more effective to achieve the intended results due to several issues. This study aims to assess and analyse the municipality’s policies that impact on the growth and prosperity of informal traders as well as the challenges that they encounter as a result of these policies. This study also monitors and evaluates the policy and implementation at municipality level. The informal traders located in the northern parts of eThekwini are focussed on as a case study. The study involved use of both secondary and primary research. In the secondary research literature review on both the informal economy and the policies that affect the people that operate within this sector was done. In the primary research structured interviews were used to gather primary data required for this study backed up by onsite observations. The results from the study show that there is lack of awareness of the informal sector policies by the informal traders. Most of the informal traders are not registered and they do not see any benefits of doing so. There is still hostility between the informal and formal traders. Informal traders highlighted a number of challenges they face every day, such as lack of shelter, storage space and running battles with law enforcers. The study showed that there was lack of involvement of the informal traders in planning such that some of the stalls that were built by the municipality remain vacant due to several issues they pointed to such as low numbers of customers in the area. The study makes some recommendations based on the findings and other studies.

The Hidden School

The EAAE Annual Conference of 2019 is titled ‘The Hidden School’, aiming to discuss an architecture school’s true character, the substance and the quality of architectural education in the broadest sense, and that which is beyond the stated curricula, yet — whether concretely manifested or subliminally perceived — embodies the culture of the school.

The Hidden School can be observed through a range of tacit aspects or conspicuous specificities which make the educational path a unique one. It is the content that can be embedded within the syllabus, learned informally, personified by educators, the attributes and activities of students, or the spaces it takes place in.

Bearing this in mind, reading between the curricular lines is crucial in evaluation, but is it possible to develop tools for the assessment of the ‘hidden’? If the hidden school exists in parallel or as a background process, a self-generated search for fundamental answers, and its interpretation, manifestation or legibility has a multitude of facets, how can these aspects be captured?

The conference, hosted in 2019 by the Faculty of Architecture in Zagreb, focuses upon the subliminal quality of architectural education, that which is beyond the stated curricula and is hard to document through quality evaluation procedures.

Published: May 2021

This paper identifies two visions of the challenge of technology integration in architecture for education. Then, the appropriateness of conceiving architecture from a holistic perspective of the human dwelling is suggested, proposing an awareness of its technological aspects. Finally, some considerations of technology in architecture, in particular in teaching and learning are challenged, first analytically and then with an integrative intention.
Students' Approach to Participating in Informal Education

Published: May 2021

The way of learning and performing practice, the tools and methods that are being used for it and the spaces that these processes take place are shifting with the change of information and technology. Under these circumstances architectural education has faced difficulties in being up to date in particular about curriculum, program and physical requirements. While instant solutions give instant results, it is inevitable that rooted solutions will be encountered to keep up with this rapid change. For this reason, countless “informal education” activities are being implemented, such as competitions, workshops, assemblies, forums, publications, etc. This paper focuses on BASS (Betonart Architectural Summer School) as a case to understand the motives of participating in such activities from the perspective of architectural students. It tries to demonstrate that students are aware of the importance of informal educational activities, furthermore they are increasingly demanding.
Mirror, Mirror….

Published: May 2021

The vast majority of architects are no longer independent designers, but part of complex design teams working with and across different disciplines. But there is resistance to professional and educational evolution ingrained in the enculturation and historic identity of architects as independent creative designers, the hidden curriculum. As long as we continue to look into the mirror for answers, are we really likely to change?
