Phosphatation de résidus minéraux
Authors: Bournonville Blandine , Nzihou Ange , Sharrock Patrick , Depelsenaire Guy
Published: November 2021

The incineration of municipal solid waste generates mineral residues which contain soluble chlorides and heavy metal pollutants. The mineral residue is currently landfilled after a cement solidification. An alternative treatment, the new patented by Solvay process uses phosphoric acid to stabilise mineral residue by the formation of stable minerals such as calcium phosphates which are insoluble in natural environments and can incorporate heavy metals inside their crystalline structure. Two different water-washed municipal solid waste incinerator mineral residues are investigated during the phosphate treatment. Phosphoric acid reacts exothermically with mineral residues with rapid kinetics of the dissolution-precipitation type. Second order rate is observed with respect to the phosphate concentration and activation energies for the phosphate reaction are found to be small (near 20 kJ/mol). Mineral residues react with phosphoric acid mainly as calcium carbonate does. Precipitated amorphous calcium phosphates coat the more inert particles (silicoaluminates, silicates, and calcium sulphates…). The two mineral residues with different compositions show similar behaviour. This indicates the phosphate stabilisation procedure can be widely applied. This chemical treatment can be considered as a first essential step in the effective insolubilisation of extractable trace heavy metals in a mineral material that could find in the future an beneficial reuse after further processing as secondary raw material.

Solvay a breveté un nouveau procédé de stabilisation de résidus minéraux contaminés par des métaux lourds et des composés organiques dont l’une des étapes fondamentales est le traitement chimique à l’acide phosphorique. Son objectif est de former des phosphates de calcium de grande stabilité chimique et thermique, capables d’incorporer dans leur structure cristalline les métaux lourds. L’étude de la cinétique de phosphatation montre que la réaction est exothermique. Les phosphates calciques formés enrobent les particules les plus inertes. L’énergie d’activation faible (20 kJ/mol), caractéristique d’une réaction acide-base, est proche de celle de la réaction avec le carbonate de calcium. Les expérimentations menées et les paramètres observés indiquent que la phosphatation peut être généralisée pour tous les résidus minéraux et constituer une première étape dans l’insolubilisation effective des métaux lourds. Ceci permet d’envisager pour le futur une possible revalorisation des résidus minéraux phosphatés et calcinés comme matière première secondaire.

Published: November 2021

Stigma ‘Desa Pengemis’ seolah melekat pada Desa Grinting, Kecamatan Bulakamba, Kabupaten Brebes. Desa ini dianggap sebagai tempat asal para pengemis di berbagai kota besar. Sebuah sebutan yang telah menjadi bagian dari memori kolektif warga, sehingga memunculkan kerisauan bersama. Kehadiran media sosial memberikan peluang bagi Warga Grinting untuk memberikan klarifikasi kepada khalayak luas bahwa desa mereka jauh dari apa yang dipersangkakan, terutama menilik dari berbagai kemajuan desa saat ini. Penelitian ini menggambarkan dan menganalisis sebuah praktik pembangunan citra sebuah desa untuk membalikkan stigma yang ditujukan kepada mereka melalui aktivitas di media sosial. Dengan pendekatan kualitatif, pengambilan data dilakukan melalui (1) analisis isi media, (2) wawancara mendalam, dan (3) diskusi kelompok terarah. Hasil penelitian menunjukkan sebuah kesadaran warga untuk merubah strategi pencitraan, dari reaktif menjadi proaktif-positif. Media sosial menjadi peluang bagi mereka untuk bersuara. Mereka berupaya menampilkan segala sisi positif desa untuk membalikkan citra sebagai desa pengemis. Mereka memiliki modal untuk melakukannya, yang didukung oleh realitas virtual dan faktual. Realitas faktual menunjukkan banyaknya pegiat media sosial dari Desa Grinting yang aktif dengan akun-akun yang berpengaruh. Sementara realitas faktual menunjukkan modal sosial yang kuat sebagai bahan pemberitaan (content sources). Realitas struktural—bahwa kegiatan pencitraan belum terkelola secara rapi dan terencana menjadi tantangan bagi mereka untuk mewujudkan citra Grinting sebagai desa yang dirindukan (ngangeni), sebagai ganti citra ‘Desa Pengemis’.
The Electrical Shanshool to Revive Al-Shanasheel in the Traditional Urban Scene in Hot Dry Areas
Authors: razaq dr. nisreen , Ibraheem Nisreen Razaq
Published: November 2021

One of the functions of Al-Shanasheel was to cool the air, but they could not compete with the Evaporative coolers, As Al-Shanasheel were a sign of luxury and wealth in Arab societies and were only built in homes of wealthy families, they are more expensive than the evaporative coolers, depending on the level of the decoration and the sculpting used to create them aesthetically, where People replaced them with evaporative coolers for their low cost, and higher cooling efficiency. One of the reasons for the disappearance of Al-Shanasheel is the absence of the functional need for them, in exchange for the high cost of construction. The diminished role of Al-Shanasheel in the contemporary urban scene, although they are one of the most famous elements of the traditional architecture in Iraq in particular and their disappearance as architectural elements of the traditional urban scene, because of its inefficiency in air cooling. The reason for the failure of the environmental efficiency of Al-Shanasheel is because there are no attempts to raise their environmental efficiency and replace them with electrical evaporative coolers. That is the research problem. So the research aimed to revive Al-Shanasheel as environmental and aesthetic elements in the urban scene by creating "The Electric Shanshool" to revive them in the urban scene. The research assumed the possibility of raising the efficiency of Al-Shanasheel in cooling the air by developing the way they work, by exploiting contemporary technologies and thus the possibility of returning them to the urban scene as dual-function elements (aesthetically and environmentally). The research has made it possible to revitalize the environmental function of Al-Shanasheel, by presenting an innovative model of electric Shanshool that cools the air of the room with the same efficiency of evaporative air cooler, while preserving the beauty of Al-Shanshool as an aesthetic and heritage element in the facades of the traditional urban scene. The manufacture, production and invention of The Electric Shanshool will contribute to achieve many of the goals adopted by many organizations. Preserving the urban, cultural and humanitarian heritage (such as UNESCO, ICOMOS, ICCROM, ALECSO, ISESCO, DoCoMo Mo of Iraq (especially for capacity building for the reconstruction of Mosul’s cultural heritage in Iraq after the mass destructions of the war)), since Al- Shanshool represents an important element in asserting the identity of the heritage of a lot of cities, and needs to be revived as it no longer meets the requirements of the present time.

Published: November 2021

Diagrid structures are evolved as one of the best structural system for high rise buildings. In this study seismic performance of 36 stories Tube-in-Tube Diagrid Structure with various diagonal slopes is evaluated by Non Linear Static Analysis. Tube-in-Tube diagrid structures are modified Diagrid structures in which gravity core is replaced with Diagrid core. Single tube diagrid structure is also studied for comparison. The structure is pushed gradually proportional to fundamental Mode shape. The analysis results shows that Tube-in-Tube structure possess higher stiffness and Lateral Load resisting capacity. The pushover analysis demonstrates that diagrid core can perform better by hardening the structure. According to analysis results, the Tube-in-Tube diagrid structure shows higher non-linear lateral displacement. It was observed that as the diagrid angle increases the stiffness and lateral load carrying strength decreases.
Otkrivanje i analiza signala parcijalnih pražnjenja u energetskom transformatoru UHF metodom
Authors:   Akcionarsko društvo „Elektromreža Srbije“ Beograd,, Dukanac Đorđe
Published: November 2021

This paper presents the practical detection of partial discharge signals using a UHF sensor mounted on a power transformer and then the detailed analysis of a signal is done. The first part of the paper describes possible partial discharge sources in power transformers, UHF method and UHF sensor. In the second part of the paper, received signal at UHF sensor is considered. In order to accurately determine the magnitude of the partial discharge signal, especially if the location of the partial discharge source is far from the location of the UHF sensor, it is necessary to separate the signal from the background noise. This is only possible at intervals between individual bursts of the observed partial discharges. The spectral composition of the received signal is considered and a method for separating the present noise from the useful components of the partial discharge signal is established. The presumable main cause of partial discharges is evaluated.
Analiza algoritama za kompenzaciju zasićenja strujnog transformatora

The main function of current transformers is to adapt the high values of the primary current to values suitable for the operation of relay protection devices, i.e. measuring devices. Under normal conditions, a current transformer transforms the current in a virtually permanent ratio, and practically without a phase shift, so the secondary current is actually a scaled value of the primary current. However, when a fault occurs in the power system, currents reach high values. As a result, the flux in the core of the current transformer can reach values above the knee of the magnetization characteristic, causing saturation of the current transformer. When saturation occurs, the secondary current is no longer a scaled value of the primary current, but is deformed. Deformation of the secondary current may cause malfunctioning of some relay protection devices. The development of digital relay protection has made it possible to perform software saturation compensation by applying certain algorithms, thus eliminating the negative consequences that saturation of the current transformer causes. In this paper, one of the possible approaches for compensation of saturation is analyzed, which is based on the application of an equivalent scheme and magnetization curve of the current transformer. Two typical approaches have been singled out, which have been analyzed and tested in more detail. Testing was performed in the MATLAB/Simulink.

Published: November 2021

With respect to both fiber and color the clothing material of Taiwan’s indigenous people came predominantly from nature. Atayal woven materials are a distinct example of how ethnic symbolism can be expressed through the combining of color and fabric patterns in weaving and dying. In order to understand Atayal fabric color use and distribution, this research first utilizes PANTONE FASHION + HOME cotton planner to contrast fabric color, and after comparison, color specimens are input one at a time into Color Schemer Studio’s color wheel statistics system. In order to analyze Atayal fabric colors, this study particularly performs color scope analysis on sub-groups for which research specimens are relatively abundant, such as the Tayal’s Beishi group and Nanao Group; and the Sediq’s Wushe Group, Wanda Group, and Taroko Group. Beishi group fabrics use a comparatively wide range of color and a more diverse number of combinations. The main colors they use include white, red, orange, yellow, green, blue, and other colors. The colors used by the Wushe Group and Wanda Group in their fabrics include white, red, blue and others. While the number of specimens collected for this study is limited, it is possible to understand, what the color preferences of sub-tribes are through their color schemes. The most predominant color schemes involve similar colors, contrasting colors, and complimentary colors.

Authors:   Department of Management, Faculty of Business Administration Enugu Campus, University of Nigeria, Achaku Mark
Published: November 2021

This study is based on secondary data and looks at the activities of Multinational Corporation and its impact on global governance from the protests movement point of view. Available data show that multinational corporations derive at least a quarter of their revenue outside their home countries. However, the debate is how significant do they contribute to development or involve in activities that lead to human and economic deprivation of host communities. The study reveals that the benefits are not enough compared to the damages. The multinational corporation uses global governance institutions to back up their interests and always get preferred treatment. The host communities who feel exploited are not happy but the multinational corporations are always innovative so, there is hope towards finding solutions. In this regard therefore, the relevant stakeholders should be engaged towards collective decision making and problem-solving in a participatory manner for effective global governance.

Although the pedagogical value of portfolio assessment is widely investigated, its impact on students’ engagement is still under-explored. Accordingly, this study intended to examine the impact of portfolio assessment on the Moroccan EFL students’ writing engagement. To this end, two groups of high school students were involved in the study. The two groups were randomly assigned into experimental and control groups. The experimental group received the treatment; portfolio assessment accompanied with various reflection and assessment techniques (i.e. self-and peer-assessment and teacher-student conferences) whereas the control group followed the regular summative writing achievement tests. To enrich the data, the experimental group students’ views about portfolio assessment were elicited via students’ written reflections. The analysis of the quantitative data showed that the experimental group students achieved a higher and more significant level of writing engagement than the control group students. Furthermore, the analysis of the qualitative data revealed that the students positively perceived portfolio assessment to impact their writing engagement at various levels.

PSYCHOLOGICAL PROBLEMS AMONG RETIRED PEOPLE
Authors: kaur Mrs. Rajwant Kaur , chauhan Dr. Krishna Chauhan
Published: November 2021

Many people experience loneliness and psychological problems in old age, either as a result of living alone or
due to lack of close family ties and reduced connections with their culture of origin, which results in an
inability to actively participate in the community activities. It has been documented that elderly are more
prone to psychological problems and depression is the commonest geriatric psychiatric disorders. In fact the
elderly in India face a multitude of psychological, social, and physical health problems. Although work
practices are becoming increasingly diverse and flexible, with far fewer people staying in a single job for thirty
or forty years, still there are many men retiring today who have been working in one role for many years. For
these men, who have not experienced much variation in their daily routine for a long time, such a major
change of lifestyle is often very stressful. Although they are more likely to own their homes, those dwellings
are more likely to be substandard. They are more likely to be in poorer health than their urban counterparts.
Yet, their health and long-term care needs are less likely to be met owing to problems in the availability of
health and social services and the obstacles to delivering services in rural areas, including low population
densities, limited transportation, and longer travel distances. No one can avoid and escape aging, but most
individuals can opt to age productively. Retirement plans and policies should be enabling, allowing executives
to address the new adjustments they need to adopt when counting down to retirement.

Published: November 2021

This article has analysed the effect of development aid flows on poverty volatility in developing countries, including through the economic growth volatility channel. Using a sample of 106 countries over the period 1980-2017, and the two-step system Generalized Methods of Moment (GMM) technique, the analysis has shown that development aid flows dampen the positive poverty volatility effect of economic growth volatility: the magnitude of the negative effect of development aid on poverty volatility rises as the degree of economic growth volatility increases. Additionally, development aid exerts a higher negative effect on poverty volatility as countries face higher poverty rates. These findings highlight the importance of development aid for stabilizing poverty rates.

Aims & Objectives: Nutrition plays a very important role in the Immunity and Immunoregulation in children. The risk of acquiring an infection is very high in malnourished and underweight children, which is what we venture out to find out in our study by researching the susceptibility for COVID-19 in children and comparing it with their nutritional status. Materials & Methods: Our Tertiary Childrens hospital had 46 COVID positive children admitted in 2020, the nutritional status analysis, showed that there were four children 8.6% (n=4) in Obese category, 19.5%, nine (n=9) children were Overweight, 17.39 %, 8 children Underweight (n=8) and 25 children were 54.3% well nourished. Results: This case series describes the various features in COVID-19 in children with and without co-morbidities primarily focusing on the nutritional profile. This is the first single centre case series globally on COVID-19. Our cohort showed no significant relation between COVID-19 and the nutritional status. We saw an equal distribution of COVID-19 in children irrespective of their nutritional status at admission. Conclusions: We did not notice any statistical significance in the age group or the nutritional status in children infected with COVID-19

Published: November 2021

Abstract
Objective: To evaluate changes in the levels of salivary irisin in chronic periodontitis, and to correlate the two.
Methods: The analytical cross-sectional study was conducted at Fatima Memorial Hospital & College of Dentistry, Lahore, Pakistan, from September 2017 to March 2018, and comprised patients of either gender visiting the periodontic out-patient department. The subjects were divided into group I, which had periodontally healthy controls, and group II, which had an equal number of chronic periodontitis patients. Chronic periodontitis was assessed on basis of pocket probing depth, clinical attachment level, plaque percentage and bleeding on probing. Also, 4ml of un-stimulated saliva was collected for the quantification of irisin protein using enzyme-linked immunosorbent assay. Data was analysed using SPSS 25.
Results: Of the 40 subjects, there were 20 (50%) in group I with 10 (50%) males and 10 (50%) females having an overall mean age of 37.60±2.58 years. The remaining 20 (50%) subjects were in group II with 16 (80%) males and 4 (20%) females having an overall mean age of 43.25±6.10 years. Mean salivary irisin level in group II was 6.80±3.97ng/ml compared to 3.99±2.48 ng/ml in group I (p=0.009). Periodontal clinical parameters in both the groups were positively but non-significantly correlated with salivary irisin levels (p>0.05) except for decreased plaque percentage in group I (p<0.05).
Conclusion: Salivary irisin levels increased in chronic periodontitis and decreased with decreasing plaque percentage in healthy individuals, indicating that this myokine can act as a biomarker for chronic periodontal disease.

A kapott eredmények szerint a magyar kis- és középvállalkozások digitális fejlettsége még lényegesen elmarad az ezen a téren legfejlettebb európai uniós tagországokétól és az EU-28 átlagától, ez utóbbihoz csak kezd felzárkózni. A tanulmány cáfolja, finomítja és árnyalja McKinsey (2018a) Magyarországra vonatkozó következtetéseit.
Egy gazdasági felzárkózás anatómiája : Ismertetés és reflexiók Muraközy László: A koreai rejtély – remetéből világpolgár (Akadémiai Kiadó, 2020, Budapest, 270 oldal) című könyvére
Authors: Fikó László
Published: November 2021

A cikk Muraközy László legfrissebb könyvét mutatja be és elemzi. A kötet a Koreai- félsziget kétezer évnyi gazdaságtörténetét fogja át, középpontjába azonban a 20. század fejleményeit helyezi, fokozott figyelmet szentelve a század második felében kiépülő fejlesztő államnak. A rövid bevezetőt követően a cikk fejezetenként tekinti át és értékeli a könyvet, ennek során az egyes fejezetek tömör bemutatásán túl több esetben ki is egészíti az ott leírtakat, valamint a hiányosságokra is felhívja a figyelmet. Az 1980-as évek demokratizálódási folyamatait és az 1997–1998. évi pénzügyi válság következményeit, illetve a kis- és középvállalkozások és a külföldi működőtőke-beruházások állami iparpolitikában betöltött szerepét lehetett volna bővebben tárgyalni, mivel ezek képezhetik a globalizációhoz alkalmazkodott fejlesztő állam eszközeit.
A szabályozáshoz való jog, a közérdekű kivételek fejlődése a kétoldalú beruházásvédelmi egyezményekben
Authors: Hajdu Gábor
Published: November 2021

A kétoldalú beruházásvédelmi egyezmények (Bilateral Investment Treaties – BIT) rendkívül elterjedtek világszerte, és számos kötelezettséget rónak az aláíró államokra. Az elmúlt évtizedekben egyre gyakrabban felmerülő kérdés, hogy az egyezményeket körülvevő bizonytalan választottbírói gyakorlat eredményeképpen szükségese rögzíteni a fogadó állam szabályozáshoz való jogát ezekben az egyezményekben (különösen bizonyos közérdekű intézkedésekre vonatkozóan), és ha igen, akkor milyen formában. A tanulmány célja, hogy megvizsgálja ennek a jognak a fejlődését kiemelhető BIT-ek rendelkezésein keresztül, kitérve mind a közvetett formáira, mind pedig a közvetlen megjelenésére. A tanulmány eredménye egy fejlődési ív felrajzolása a feldolgozott BIT-ek alapján, illetve a szerző röviden de lege ferenda jellegű javaslatot tesz a kérdés megoldására, illetve következtetéseket von le a várható jövőbeli fejleményekről.
Az iráni vízválság a klímaváltozás és a növekvő társadalmi elégedetlenség árnyékában
Authors: Szálkai Kinga , Szabó Miklós
Published: November 2021

Az elhúzódó és egyre súlyosbodó szárazság 2021 nyarán több halálos áldozatot követelő tüntetésekhez vezetett Iránban. A jelen interdiszciplináris tanulmány célja, hogy a hidropolitika és a kulturális antropológia perspektíváiban vizsgálja meg az iráni vízválság természeti és antropogén kiváltó okait, valamint a politikai, gazdasági és társadalmi következményeit. Elsőként a szárazsághoz vezető fő tényezőket tárjuk fel, s bemutatjuk, hogy a klímaváltozás hatásai mellett a közvetlenül az emberi tevékenységből származó következmények is nagy szerepet játszottak a helyzet kialakulásában. Ezután két konkrét esettanulmányt, az Orumije-tó és a Zájanderud folyó példáját vizsgáljuk meg, amelyek jól tükrözik a válsághelyzet általános jellemzőit. A következő szakaszban a vizsgálódás fókuszát kiterjesztjük a válság által leginkább érintett két tartományra, Huzesztánra, valamint Szisztán és Beludzsisztánra, míg végül, de nem utolsósorban az iráni vízválság regionális vonatkozásait elemezzük az Irakkal és Afganisztánnal fenntartott vízügyi kapcsolatok esetében.
Az Eurázsia-narratíva kibontakozásának vizsgálata a magyar kormányzati nyilatkozatok és fejlesztéspolitikai dokumentumok tükrében
Authors: Salamin Géza , Megyesi Zoltán , Klemensits Péter
Published: November 2021

A magyar kormányzat a 2008-as gazdasági válság hatásaira, valamint a világgazdaság súlypontjának keletre vándorlására tekintettel a keleti nyitás politikája mellett kötelezte el magát, azaz a keleti feltörekvő piacok felé irányuló export növelését, ezáltal a kivitel diverzifikálását célozta meg. A 2010 óta stabilan kormányzó politikai erő részéről a külgazdasági koncepció mellett az elmúlt tíz évben egy Eurázsia köré épülő geopolitikai narratíva is kikristályosodott. A tanulmány a Gearóid Ó Tuathail által megfogalmazott gyakorlati geopolitikai érvelési modell alkalmazásával, a kormányzati szereplők beszédei, interjúi és esemény-összefoglalói, illetve a fejlesztéspolitika tervdokumentumai alapján igyekszik beazonosítani és értékelni a magyar Eurázsia-narratívát, továbbá bemutatni az annak megvalósítására tett legfontosabb lépéseket és azok külső feltételrendszerét.
A Case Study to Improve the Quality of Median Filter
Authors: Alqadi Ziad A. , Barakat Mohamad Tariq
Published: November 2021

The median filter is used to reduce the effect of noise, but it treats all pixels, whether they are noise points or not, which negatively affects many non-noise values in the digital image, and the negative effect increases as the noise ratio increases. In order to get rid of some of the disadvantages of the median filter, we will present in this research paper a detailed study that works on treating the unaffected and infected pixels so that this treatment leads to improving the performance of the filter by raising the values of the quality factors of the filter. The improvements added to the median filter will raise the efficiency of the noise reduction process, especially for high noise ratios.
Mermaids
Authors: Müller Axel , Halls Christopher , Williamson Ben
Published: November 2021

Women with fish tails are among the oldest and still most popular of mythological creatures, possessing a powerful allure and compelling ambiguity. They dwell right in the uncanniest valley of the sea: so similar to humans, yet profoundly other. Mermaids: Art, Symbolism and Mythology presents a comprehensive, interdisciplinary and beautifully illustrated study of mermaids and their influence on Western culture. The roots of mermaid mythology and its metamorphosis through the centuries are discussed with examples from visual art, literature, music and architecture—from 600 BCE right up to the present day. Our story starts in Mesopotamia, source of the earliest preserved illustrations of half-human, half-fish creatures. The myths and legends of the Mesopotamians were incorporated and adopted by ancient Greek, Etruscan and Roman cultures. Then, during the early medieval period, ancient mythological creatures such as mermaids were confused, transformed and reinterpreted by Christian tradition to begin a new strand in mermaid lore. Along the way, all manner of stunning—and sometimes bizarre or unsettling—depictions of mermaids emerged. Written in an accessible and entertaining style, this book challenges conventional views of mermaid mythology, discusses mermaids in the light of evolutionary theory and aims to inspire future studies of these most curious of imaginary creatures.
