“We, The Inuit of Labrador”: Balancing Inuit and Western Traditions in the Nunatsiavut Constitution
Authors: White Graham
Published: April 2021

Canada’s Indigenous peoples have slowly been reclaiming control over their lands and lives. As a wide range of institutions emerges, designed to enhance Indigenous peoples’ ability to govern themselves according to their own principles and priorities, academic attention is shifting from normative arguments about the need for self-government to the study of actual institutions. This article examines the constitution of the Nunatsiavut Government, the self-government regime established by the Inuit of Northern Labrador in 2005. The Nunatsiavut Constitution is a lengthy, formal document that not only sets out in detail the structures of the Nunatsiavut Government and how they are to operate but also proclaims the cultural and political aspirations of the Labrador Inuit. It is thus an instructive case for the consideration of how, and to what extent, Indigenous self-governments accommodate the tensions between Indigenous forms and norms of governance with the structures and principles of Western governance. Particular attention is devoted to the design of the only Inuit self-government in Canada, to the influence of Inuit culture on the organization and operation of the Nunatsiavut Government, and to constitutional provisions relating to the role of women in government and in society generally. The article is based on a close reading of the document, supplemented by interviews with key figures involved in the development of the constitution and with present-day Nunatsiavut Government officials.
Maple-Glazed Populism: Political Opportunity Structures and Right-Wing Populist Ideology in Canada
Authors: Budd Brian
Published: April 2021

While initially immune to the outbreak of right-wing populism observed in other established Western democracies, recent elections and political developments at the provincial and federal levels of politics demonstrate that populism has entered the political mainstream in Canada. This article examines these developments in a broader historical context by charting the evolution of right-wing populist ideology in Canadian federal politics. Using existing genealogical frameworks of right-wing populist ideologies, the argument is advanced that contemporary populist leadership in Canada has largely developed to adopt the discursive and ideological tenets of what scholars have defined conceptually as neoliberal populism. The article positions this trend of ideological moderation as the outcome of institutional and medium-term opportunity structures inherent to Canada’s electoral and party systems. This relationship is demonstrated through an examination of the ideological evolution of contemporary Canadian right-wing populism beginning with the Reform Party in the late 1980s through to the People’s Party of Canada in the 2019 federal election. The analysis shows that, while initially championing exclusionary positions on multicultural accommodation and immigration, Canadian right-wing populists gradually revised their programmatical appeals through an embrace of neoliberalism as part of a purposeful strategy to try and extend their national electoral viability under Canada’s single-member-plurality electoral system. The article concludes by offering an analysis of the People’s Party of Canada and its promotion of radical right-wing populist ideology in the 2019 federal election. The argument is advanced that, rather than attributable solely to the transnational diffusion of far right ideologies, the emergence of the People’s Party is evocative of a domestic shift in medium-term opportunity structures that has helped to create ideological space for the mainstreaming of radical positions on immigration and multiculturalism in Canada.
Nationalism, Secularism, and Ethno-Cultural Diversity in Quebec
Authors: Béland Daniel , Lecours André , Schmeiser Peggy
Published: April 2021

An ongoing debate over the intersections between secularism and ethno-cultural diversity is taking place in contemporary societies. For example, in just over a decade, Quebec has witnessed multiple attempts to reframe its approach to issues of nationalism in the context of secularism and the regulation of ethno-cultural diversity. This qualitative and historically minded article studies the relationship among nationalism, secularism, and the regulation of diversity, through three stages of analysis. First, it explores the Catholic history of Quebec and the secularization dimensions of its nationalism since the Quiet Revolution and the ongoing debate within the province about religious accommodation and the integration of immigrants. Second, it lays the stage for examining the political and historical rise of the recently passed Bill 21 An Act Respecting the Laicity of the State in Quebec, through analysis of the failed, yet pivotal, proposal for a “Quebec Charter of Values” during the leadership of Parti Québécois (PQ) Premier Pauline Marois (2012–14). Throughout this article, the content of the charter under the PQ and the successful Act under the Coalition Avenir Québec are discussed in light of policy transfer from France to Quebec regarding secularism and the public display of religious symbols, as well as Quebec’s unique context within the Canadian federation. Finally, it turns to recent political and policy developments in Quebec, including the passing of the new Act, as they relate to the changing relationship among nationalism, secularism, and diversity.
Current concept of oral health and its potential implications for policy and practice of dental health coverage and insurance: Post COVID-19 measurement
Authors: Che Musa Muhd Firdaus , Ab. Halim Noorhazayti , Sayed Kamar Syarifah Haizan , Abllah Zurainie , Supaat Salwana , Mohd Ibrahim Mohamad Shafiq
Published: April 2021

This review paper aims to succinctly discuss the current concept and definition of general and oral-health and its potential implications on policy and practice in regards to the dental health coverage/insurance post COVID-19 pandemic. In general, dental policies and coverage are treatment-oriented, largely focus on curative procedures with some portion for preventive care despite most of dental diseases being largely preventable. There is however still no universal consensus definition of health, leading to mixed-feeling in setting-up priorities and direction for health policy. The FDI-World Dental Federation has then published a new definition of oral-health, highlighting the broader determinants of oral-health and envisioning a discussion on the implications of this definition and, in particular, how to transform the new oral health framework into a policy and practice agenda. In Malaysia, it is predicted there will be increasing demand for public dental coverage post COVID-19, however the government is yet to be ready in fulfilling those needs, leading to worsening oral-health inequalities. The lack of healthcare expenditure with no health social-insurance model reduces the affordability and accessibility of patients to private services. Moreover, such narrow definition of oral-health, as influenced by the previous policies led to a limited coverage for common dental diseases, including oral health-related deformities linked to oral cancer and injuries. These are the major challenges for Malaysia. The government should therefore working in partnership, start subsidising dental fees of private health insurance, focus and integrate disease prevention and health promotion within it, to achieve WHO-goal of universal health coverage.
The use of bioceramic root canal sealers for obturation of the root canal system: A review
Authors: Mustaffa Musliana
Published: April 2021

The use of bioceramic root canal sealers in endodontics is a promising approach because of the advantages such as improved flow properties, biocompatible and could promote the formation of hard tissue. Due to the recent technology and limited scientific evidence, the effectiveness of bioceramic root canal sealers remains unclear. This article focuses on the physicochemical properties, biocompatibility, biomineralisation, retreatability, 3D obturation and current practice of using bioceramic root canal sealers. The relevant articles for this review were searched manually from Google Scholar and PubMed using keywords ‘bioceramic root filling material AND endodontics’, ‘bioceramic root canal sealers AND endodontics’, ‘cytotoxicity AND bioceramic root canal sealers’, ‘bioceramic root canal sealers AND physicochemical properties’, ‘biomineralisation AND bioceramic root canal sealers’ and ‘retreatment efficacy AND bioceramic root filling materials’. Since the clinical data concerning the obturation with bioceramic root canal sealers is lacking, the selection of materials should be made based on the available scientific evidence, individual cases, material availability and operator’s preference.

Authors: Binartha Ciptadhi Tri Oka , Kardinal Yessica Puspita , Widyarman Armelia Sari
Published: April 2021

Successful of periodontal treatment is to eradicate biofilm of bacteria. Aggregatibacter actinomycetemcomitans is a Gram-negative bacterium that have been suggested to be the main causes of periodontal disease. Theobroma cacao (cacao pod) is a medicinal plant that has a broad range of pharmacological effects. The aim of this study was to assess the antibiofilm effect of cacao pod extract against A. actinomycetemcomitans biofilm in vitro. A. actinomycetemcomitans were cultured in Brain Heart Infusion broth.  Crystal-violet staining in biofilm assays were used to evaluate the cacao pod extract effect on A. actinomycetemcomitans ATCC 33384 biofilms and 0.2% chlorhexidine-gluconate was used as a positive control. After 24 hours of incubation, the optical density of each well in microtiter plates was measured. The results showed that the biofilm density after incubation with the cacao pod extract was significantly decreased in all concentrations and all incubation times (p<0.05). The most effective concentration for inhibiting biofilm A. actinomycetemcomitans was 100% cacao pod extract and 3 hrs of incubation time (p<0.05) with a 98.9% reduction of biofilm compared to negative control. Cacao pod extract is effective in inhibiting the growth of A. actinomycetemcomitans biofilm.

The analysis of allelic polymorphism of five industrial egg crosses of chickens by five microsatellite DNA loci (ADL0268, MCW216, LEI0094, ADL0278, and MCW248) was carried out. DNA loci were chosen according to the recommendations of the International Society for Animal Genetics (ISAG). Based on the results of mathematical-statistical processing and data analysis, the spectra and frequencies of allelic variability, the peculiarities of allele pools, were identified, and unique alleles were identified. In general, the species Gallus gallus is characterized by a specific character of allelic spectra for all investigated microsatellite DNA loci (P <0.001). The highest rates of allelic variability were recorded in brown crosses "Lohmann brown" and "Hisex brown" (Na (LimNa)=(9.2 (5-17) and 7.4 (6-11), respectively). The studied crosses were characterized by a shift in allelic spectra towards a decrease in the fragment length. “Lohmann white” stands out among the birds of other crosses by high consolidation for individual alleles for all studied microsatellites (from ADL278114 – 0.343 and ADL268108 – 0.485 to LEI094259 – 0.720, MCW0248213 – 0.785 and MCW0216137 – 0.920). Unique alleles with the highest frequency were found in brown cross chickens, and in the “Hy-Line W-98” bird, they were not found. The number of unique alleles identified varied from 1 ("Hisex white") to 11 ("Lohmann brown"). Locus LEI094 turned out to be the most polymorphic in terms of the number of unique alleles – 10 such allelic variants were identified for it. No unique alleles were identified at the ADL0268 locus. The obtained estimates criterion χ2 of K. Pearson indicate significant differences in the frequency distribution of alleles for all studied loci. When using the MICROSATELLITE ANALYSER software, it was found that the nature of the variability of the studied microsatellite DNA loci in five industrial crosses of the egg chickens, both in the number of identified alleles and in the nature of their distribution, corresponded to the stepwise mutation model (SMM).
When 7 times angioplasty on Saphenous Vein graft would not compete the Native vessel Percutaneous Coronary intervention
Authors: Khalilipur Ehsan

Coronary artery bypass graft (CABG) has been the first option for revascularization in multiple vessel coronary artery disease. One of the most major obstacles after CABGs is atherosclerotic changes of SVGand more than 50 percent ofSVGare occluded at 10 years and 25 percent show severe stenosis at angiographic follow-up. Whether native vessel percutaneous coronary intervention (PCI) on native vessel or saphenous vein graft intervention is of benefit in these patients is still a debate. In this case report we want to clarify a common clinical scenario in a patient with prior CABG seven years ago which a proper decision in the right time could save many futile efforts. The patient underwent 7 PCI on the diseased SVG on OM with frequent occlusion due to stent thrombosis and in-stent restenosis which finally native vessel antegrade CTO PCI alleviated the problem and patient followed up 2 months after the procedure without any chest pain in his ordinary activities.

But they must be carried out as the author suggests, through: the application of various high-tech electronic means (bracelets and microchips); revision - separate powers and NPA, regulating the activities not only of the UUP (district police commissioners) of the police department, employers (owners), but also local authorities of the executive branch (OMS) of the subjects of the Russian Federation, initiated by the territorial body of the Russian Interior Ministry on the subject of the Russian Federation.
The Socio-Theoretical Relevance of Erich Fromm’s Psychoanalytic Conception of Narcissism
Authors: Sakurai Takamichi
Published: April 2021

This article methodologically explores Erich Fromm’s theory of narcissism in socio-theoretical terms while referring to his theory of alienation. It thereby portrays the foundations of an analytical method of far-right politics in the context of capitalism and demonstrates that malignant narcissism touches off fascism without regard to authoritarianism. Essentially, the Freudian psychoanalytic concept of narcissism lies in Fromm’s social theory. However, it is possible to discern the theoretical essence of his social theory characteristically in his conception of alienation. By focusing on this theoretical concern, I argue that in Fromm’s social theory the concept of narcissism works on a sociopathological level, particularly in the way in which it synchronises with alienation, a social phenomenon that fulfils its important functions in conjunction with the marketing orientation under the conditions of a market society, and therefore that the concept plays an overriding role in his theory of alienation. I conclude that the relevance of a Frommian critical social theory of narcissism for our society is best showcased by the concept of postfascism.
Communication, Context, and Narrative
Authors: Hassanzadeh Navid
Published: April 2021

Although often cast by realists as an exemplar of moralist or rationalist thinking, Jürgen Habermas and certain commentators on his work reject this characterisation, highlighting elements of his thought that conflict with it. This article will examine dimensions of Habermas’s work that relate to many realist concerns in political theory. I argue that while he escapes the commonplace caricature of an abstract thinker who is inattentive to real world affairs, Habermas’s claims in relation to communication, historical and empirical context, and the development of rights in history, reveal a narrow consideration of what defines context and a progressivist narrative of history that fails to address seemingly outdated beliefs and political forces. An analysis of these issues can serve to inform understandings of these topics in realist thought and in political theory more broadly.
Pashto-English Contact: The Role of Suffixation in Hybridizing Lexical Items
Authors: Ahmad Nisar , Iqbal Liaqat , Atif Muhammad
Published: April 2021

The study investigates the role of suffixation in Pashto-English hybridization at the word level and the sociolinguistic significance of such hybridization. Data from electronic media, including programmes from Khyber News, representing both formal and informal domains of language use, is used for the study. The programmes selected include Top Stories, News Hour, Mohim Repotuna, Naway Sahar and Sports Mag. Employing content analysis as a research method, a quantitative approach for the investigation of hybridized English lexical category and a qualitative approach for its sociolinguistic significance have been used. The present study employs the framework presented by Kachru (1978), as adapted by Rasul (2006). The findings of the research show that noun is frequently hybridized both in formal and informal domains of language used mostly by the addition of Pashto inflectional suffixes. It is concluded that suffixation got an important role in Pashto-English hybridization that leads to the creation of hybrid forms predicting language shift and the emergence of a new variety of Pashto.
Cultural and Historical Progression: The Psychology of Literary Allusions in Theodore Dreiser's The Financier (Trilogy of Desire)
Authors: Aurangzeb Sahibzada , Iqbal Liaqat , Jehanzeb Sahibzada
Published: April 2021

The psychology of allusion is often multi-faceted as a reference to an artefact, which could be a character from a literary piece, the quoted words of a character, a place in the country or an event from history. The reference item should be familiar to the readers. The current research identifies literary allusion in The Financer (1912) and the characters referred to Ouida's Tricotrin (1869), Charlotte Bronte's Jane Eyre (1847), Amelia Edith Huddleston Barr's A Bow of Orange Ribbon (1886), Edward Bulwer Lytton's Kenelm Chillingly (1874), and William Shakespeare's Macbeth (1603) which is explained with reference to the plot of Theodore Dreiser's Trilogy of Desire: The Financier (1912), The Titan (1914) and The Stoic (1947). The available literature review testified that a thorough evaluation of the allusions within the novel had not been accomplished to date, although these allusions link the literary pieces of the greatest minds in literature.
Potensi Ruang Terbuka Hijau dalam Penyerapan Co2 Di Permukiman Studi Kasus : Perumnas Sarijadi Bandung dan Cirebon
Authors: Hastuti Elis , Utami Titi
Published: April 2021

Kondisi pembangunan perumahan di perkotaan yang sangat pesat cenderung meminimalkan  dan melakukan alih fungsi ruang terbuka hijau (RTH). Penghijauan diperlukan untuk  peningkatan kualitas ekosistem perkotaan, dengan menciptakan iklim mikro yang sehat dan nyaman melalui peningkatan luasan hijau sebagai penyerap emisi CO2 dan  polutan udara.Melalui  penelitian  perumahan berdasarkan karakter lokasi, aktivitas penduduk, dan  potensi pengembangan  RTH,  maka dilakukan pemilihan sampel  perumahan di Bandung dan Cirebon, yang  menunjukkan perbedaan karakteristik RTH. Pendekatan analisis untuk pengembangan RTH dilakukan  berdasarkan kebutuhan luasan hijau dan potensi penyerapan CO2. Di Perumnas Sarijadi, Bandung, menunjukkan tingkat penanaman tanaman dengan luas lahan hijau per rumah sekitar 2,46 m2/orang, dengan luas lahan hijau  di setiap rumah   berkisar antara 0-20 %. Sementara di Perumnas Burung-Gunung dan GSP mempunyai  tingkat luasan hijau  per rumah yaitu 1,02 – 1,84 m2/orang, dengan  prosentasi luas lahan hijau setiap rumah sekitar 0-20 %. Di lokasi RW 08 dan RW 09, Perumnas Gunung, saat ini RTH yang ada hanya 7 -10 % dari luas kawasan dengan luasan hijau sekitar 3,33 - 4,25 m2/orang. Untuk meningkatkan kualitas lingkungan  di permukiman, maka selain  peningkatan luasan hijau, juga diperlukan keanekaragaman sesuai  fungsi serapan, kondisi tanah, ataupun segi sosial. Penataaan bangunan dengan rumah susun harus mulai digalakkan sehingga untuk ruang terbangun yang dialokasikan 60 % di Perumnas Sarijadi agar  dapat mememuhi standar kebutuhan lahan hijau dengan minimum RTH sekitar 33 %. Sementara di Perumnas Gunung, penerapan konsep ‘roof garden’ atau penghijauan vertikal dapat menjadi alternatif untuk memenuhi kebutuhan lahan hijau penduduk dan penyerapan polutan kendaraan karena peningkatan luas RTH tidak mencukupi dari sisa lahan yang ada jika area terbangun dialokasikan 65 %, maka  kebutuhan RTH mencapai lebih dari 35 %.

Peran Kemitraan dalam Penataan Ruang Terhadap Pengendalian Permukiman
Authors: Iriani Lia Yulia
Published: April 2021

Pengendalian Perumahan dan Permukiman merupakan salah satu muatan materi UU No.4/1992. Dalam aplikasinya berhubungan dengan ketentuan penataan ruang, yang memerlukan kebersamaan dan kemitraan dalam penyelenggaraannya dengan melibatkan seluruh pemangku kepentingan, sebagaimana tercantum pada pasal 2 huruf f UU No.26/2007. Hal ini merupakan paradigma baru salah satu ketentuan penataan ruang yang tidak tercantum pada UU No.24/1992. Hubungan timbal balik antara penataan ruang kaitannya dengan pengendalian permukiman sebagaimana tercantum pada pasal 7 ayat 1 dan 2 UU No.4/1992, dimaksudkan untuk membentuk suatu sistem hukum yang memberi dasar jelas dan tegas serta  menyeluruh bagi upaya pemanfaatan dan pengendalian permukiman di kawasan perkotaan maupun perdesaan namun  peraturan tersebut perlu segera dirubah karena sudah tidak sesuai lagi dengan perkembangan saat ini. Salah satu hasil litbang berhubungan dengan hal tersebut menyatakan 71,43 % responden ketentuan UU No.4/1992 perlu disesuaikan dengan aturan baru dan  karakteristik daerah, 28,57% aturan permukiman belum bisa mengendalikan timbulnya permukiman kumuh. Untuk itu diperlukan aturan yang lebih jelas dalam hal mengaplikasikan keterpaduan dalam penataan ruang di masyarakat.
Mengurangi Pemanasan Bumi Dengan Pola Hidup Hemat Energi

Published: April 2021

Pada tahun 2001 Panel Perubahan Cuaca Antarpemerintah atau IPCC (Intergovernment Panel on Climate Change) yang dalam salah satu  laporannya  menegaskan, beberapa dampak yang terjadi dari perubahan iklim (climate change) di daerah tropis Asia.  Diprediksi daerah ini sangat rentan atau mudah terserang oleh dampak yang ditimbul oleh perubahan iklim dan khususnya risikonya akan  sangat tinggi pada  daerah–daerah banjir sekalipun dalam musim kemarau. Selama abad yang lalu manusia pada dasarnya sudah menambah atau meningkatkan gas rumah kaca (GRK) ke atmosfer, dengan membakar minyak bumi untuk menjalankan mobil, pabrik, utilitas serta peralatan untuk kegiatan sehari-hari, sehingga terjadi penambahan gas karbon dioksida dan metane yang memberikan kontribusi kenaikan suhu bumi dan perubahan cuaca. Dua puluh tahun yang lalu sebetulnya kita sudah mengetahui hal ini akan terjadi dan dampak yang banyak dirasakan  oleh masyarakat dunia adalah, terjadinya kenaikan suhu bumi, kenaikan muka air laut, banjir, angin topan, berkembangnya penyakit demam berdarah  dll. Beberapa perusahaan besar di dunia dalam pengolahan produknya, secara sukarela  bekerja sama dengan WWF sudah mulai mengurangi emisi CO2 dengan melakukan penggantian peralatan produksi serta  bahan bakar minyak ke bahan bakar alternatif yang ramah lingkungan seperti, angin, biomass, energi geotermal dll. Keuntungannya  yaitu sebesar $ 100 juta dan ini  merupakan prospek ke depan yang bagus  dalam rangka pengurangan emisi CO2 yang ditargetkan pada tahun 2010 dapat mencapai  10 ton per-tahun atau setara dengan 10 juta mobil yang sedang beroperasi di jalan. Apa yang bisa kita lakukan? Kita harus mulai sedikit merubah pola hidup di rumah dan sekitarnya, melalui penghematan penggunaan energi listrik, air, bensin, menciptakan desain rumah serta penggunaan bahan bangunan yang hemat energi  serta ikut menjaga kelestarian lingkungan  sekitar, hutan dan polusi udara. Partisipasi masyarakat yang sekecil apapun jika dilakukan secara global akan memberikan arti yang cukup besar dalam mengurangi pemanasan global.

Authors: Ashuri Amallia , Kustiasih Tuti
Published: April 2021

Pantai Pangandaran yang berlokasi di Kabupaten Pangandaran merupakan salah satu destinasi wisata yang terkenal di Provinsi Jawa Barat dan destinasi wisata strategis nasional. Peningkatan jumlah wisatawan di Pantai Pangandaran belum disertai dengan pengelolaan persampahan yang baik menyebabkan penumpukan sampah pada saat musim puncak liburan sehingga terjadi penurunan estetika, ketidaknyamanan pengunjung, serta pencemaran lingkungan. Untuk itu perlu dikembangkan suatu sistem pengelolaan sampah untuk sampah wisata dan bawaan laut yang dihasilkan di Pantai Pangandaran. Dalam penelitian ini dilakukan suatu studi mengenai timbulan dan komposisi sampah wisata dan bawaan laut dimana hasilnya diharapkan dapat dijadikan dasar oleh stakeholder terkait dalam menentukan sistem pengelolaan maupun teknologi pengolahan sampah yang tepat untuk diterapkan di Pantai Pangandaran. Hasil penelitian menunjukkan bahwa timbulan sampah dari hotel di Pantai Pangandaran cenderung tinggi, salah satunya disebabkan oleh penggunaan kamar yang melebihi kapasitas. Hasil penelitian juga menunjukkan bahwa sampah wisata banyak didominasi oleh sampah dapur dan sisa makanan (44,68%) serta sampah daun (13,48%). Kedua jenis sampah ini dapat diolah dengan baik dengan pengomposan maupun biodigester. Sementara sampah bawaan laut didominasi oleh sampah plastik (28,32%), batang kayu (25,15%), dan batok kelapa (27,33%). Reduksi sampah bawaan laut dapat dilakukan dengan cara menjual kembali sampah kepada bandar sampah. Selain itu, pengelolaan sampah bawaan laut tidak terlepas dari pengelolaan sampah daerah aliran sungai yang bermuara di pantai karena sampah bawaan laut banyak berasal dari darat.

Published: April 2021

Modulus penampang elastik balok merupakan salah satu parameter yang berkaitan dengan kekuatan dan kekakuan balok, secara khusus berhubungan dengan momen inersia penampang. Modulus penampang elastik balok kayu utuh (solid) tidak sama dengan balok kayu laminasi untuk studi kasus balok dengan ukuran penampang sama, hal ini dikarenakan momen inersia penampang balok laminasi perhitungannya berbeda dengan balok utuh akibat adanya slip antar lamina pada saat beban bekerja serta besarnya modulus elastisitas yang tidak sama pada setiap lamina, sehingga perilaku lentur balok menjadi satu kesatuan dalam kaitannya dengan kekuatan balok. Tujuan penelitian ini adalah mempelajari modulus penampang elastik balok kayu laminasi lem (glulam). Ruang lingkup penelitian yaitu benda uji balok terbuat dari kayu Jabon (Anthocephalus cadamba Miq.) ukuran penampang 60x160 mm, jumlah lamina 4 (empat), sistem laminasi menggunakan lem super adhesive, pengujian lentur menggunakan metode four-point loading test, perilaku lentur yang ditinjau adalah kekuatan lentur, modulus penampang elastik, dan rasio daktilitas balok. Hasil penelitian memperlihatkan bahwa modulus penampang elastik dan tegangan lentur balok kayu laminasi lem lebih rendah dibandingkan balok kayu utuh dengan rasio sebesar 0,54, serta rasio daktilitas balok kayu laminasi diperoleh sebesar 1,28 sehingga termasuk dalam kriteria daktilitas terbatas. Hasil pengujian mengindikasikan bahwa kegagalan balok kayu laminasi lem adalah berupa kegagalan lentur. Parameter modulus penampang elastik balok kayu laminasi berguna untuk desain komponen struktur balok pada bangunan khususnya pada perhitungan kekuatan balok dan kekakuan balok sebagai persyaratan serviceability.
Regularities of the influence of submicron ceramic powders TiO2, AlN, Cr2O3 on the tribological properties of a friction material
Authors:   O.V.Roman Powder Metallurgy Institute, Leshok A. , Dykha A. ,   Khmelnitskyi National University
Published: April 2021

Friction units for automotive and special vehicles are designed to operate under boundary friction conditions. Modern vehicles contain friction assemblies that use friction materials. Currently, friction materials are actively used: based on thermosetting resins; pulp and paper-based materials; sintered powder materials; materials of carbon or carbon composition; materials with a ceramic matrix. The development of a unified understanding of the effect of the size and chemical nature of ceramic additives on the processes occurring in a friction material during friction is very important and can be obtained both on the basis of experimental and theoretical studies. The paper presents the results of a study of the effect of submicron TiO2, Cr2O3, AlN powders with a size of 0.2-0.5 microns on the tribotechnical properties of a frictional material based on copper intended for operation under boundary friction conditions. It was found that when using the addition of Cr2O3 powder, the greatest increase in the value of the friction coefficient is noted - from 0.042 to 0.082, a slightly smaller increase in the friction coefficient is shown by the use of AlN and TiO2 defects - 0.042-0.074 and 0.042-0.060, respectively. The least wear of the friction material was obtained when using 3.0 vol. % aluminum nitride additive - 2.1 microns / km. Increasing the addition of any of the submicron powders by more than 7 vol. % leads to a significant decrease in wear resistance. This is due to the formation on the surface of the friction material of a modified layer containing ceramic particles and the metallic phase of the friction material. For the friction material, an unstable value of the friction coefficient and increased wear were recorded

It is necessary it is not simple to catch SA, but to filter in the closed system, clean and give filtered clean y air in the area of deposition, technology and metallurgical properties of process of depositing must not be broken here. Features of the mechanical cleaning are in technologies of deposition, characterized that air-gas mixture has a temperature which influences on a sorbent. The mechanical cleaning by the centrifugal chamber of cleaning (CCC) is the modernized cyclone filter where centrifugal forces and gravities were used. Differs from existent cyclic filters a presence by a conical spiral insertion and rearranged surface of cone which engulfs it. In the entrance tangential union coupling appears, divided aero mixture into a few streams of entered in a spiral insertion. In the electric filter (electrostatic) electric forces operate on particles and gas molecules (based on the phenomena ionization of gas molecules, by an electric charge in the electric field). An electric charge is revealed to the particles, and they under the action of the electric field are besieged from a gas stream. If such gas, containing the several of transmitters of charges, to place between electrodes, connected with the source of high voltage, ions and electrons will begin to move to on power the field lines .

The analysis of antifriction polymer compositions on the basis of polyamide, epoxy, phenol-formaldehyde, furan resins, and also on the basis of fluoroplastic with various fillers working in friction knots is made. The influence of fillers on the mechanisms of friction is little studied, so when creating antifriction compositions capable of working in conditions of lubrication in water, the following tasks were set: to justify the number and type of fillers; to investigate the influence of fillers on the process of wear of material and counterbody; determine the optimal composition of the antifriction composition that provides minimal wear of the coating and the counterbody. The object of study were: compositions based on phenol-formaldehyde resin and fluoroplastic, modified with antifriction fillers; details of submersible pumps. The basis of the study was the study of tribotechnical and technological properties of polymer compositions. Based on the analysis of literature data, the target fillers for the creation of antifriction compositions for radial plain bearings and thrust bearings of submersible pumps are selected, their number and composition are substantiated. The criterion for optimization was the mass wear of the polymer coating and the counterbody. The optimal composition of the antifriction composition for radial plain bearings, which contains: a mixture of colloidal graphite Cl and carbon fabric "TGN-2M"; molybdenum disulfide DM-1; powder polyamide 12 APN-B; crushed prepreg comprising a fiberglass filler impregnated with a modified phenol-formaldehyde resin P2M. For thrust bearings, the optimal composition of the fluoroplastic composition is determined, which includes: fluoroplastic F4; molybdenum disulfide; carbon fabric; powdered copper. The physical and mechanical properties of the optimal composition are presented. Technological equipment has been developed for the restoration and manufacture of plain bearings and submersible pump bearings. Molds are made for industrial implementation.

The article considers the technology of electroerosive treatment of steel friction pairs and presents the results of experimental studies. Analysis of experimental studies has shown that an increase in the anode-cathode voltage leads to a sharp decrease in the microhardness of the surface layer. The study also allowed to determine the characteristic size of the structural elements, the height parameters of the surface roughness. The elemental composition of the initial surface of the sample made of steel 15HGN2TA differs from the composition of the coatings and surface layers of the samples modified by electroerosive treatment with different electrodes. In the mode of operation of the "anode - cathode" system on the cathode surface due to dissipative processes, a thin layer of coating of a stable modified structure is formed. It is shown that the height of surface irregularities in the areas after friction is higher than in the areas of the surface outside the friction track, which is associated with the formation on the surface of the samples of the friction transfer film. It was found that the frictional interaction of steel samples treated by electroerosion method forms a thin film on the friction surface of steel samples, which leads to a change in the topography of surfaces with increasing height of microroughnesses and structuring of the transfer film in the sliding direction. The influence of electroerosive treatment of steel surfaces on the wear resistance of the metal-polymer tribosystem was established and the optimal treatment modes were obtained: voltage U = 145-150 V, capacitor capacity C = 225-230 μF, treatment duration t = 3-4 min / cm2, providing the greatest reduction in speed wear of the polymer counterbody and recommended in the development of technological processes of electroerosive treatment.

The paper considers possibilities to increase the wear resistance, corrosion resistance, and service life for parts machines and mechanisms via their hardening and renovating using electric arc coatings characterized by high density, adhesion strength, and micro hardness thanks to activation of the spraying process. Also, the possibility of controlling the properties of restored surfaces owing to choice of the related equipment with required structure and characteristics in order to prolong the service life of machinery parts is shown. The right choice of equipment for spraying makes it possible to increase the speed and temperature of the spraying gas and particles, reduce the droplet diameter, increase the density and reduce the oxidation of coatings. The influence of spray factors such as the flow rate and pressure of working gases, composition of combustion mixture, spraying distance, dispersion of the spray, properties of wire material, etc. on the properties of the coatings obtained has been investigated. The possibility of controlling the properties of surfaces owing to choice with required characteristics electric arc coatings is shown. The influence of spray factors such as the flow rate and pressure of working gases, composition of combustion mixture, spraying distance, dispersion of the spray, properties of wire material, etc. on the properties of the coatings obtained has been investigated. The use of coatings makes it possible to increase the wear and corrosion resistance of working surfaces of machine parts and mechanisms, in particular ship parts, and so to reduce the costs of alloyed steels and alloys. The coatings application is associated with implementation of a fundamentally new approach, according to which the strength and carrying capacity of a part is provided by its basic material, whereas the resistance to corrosion, wear, and other factors may be increased via using hardening protective coatings. There are many alternative methods for producing coatings, from which it is advisable to choose an optimal, easy to implement, and inexpensive one. Of the variety of methods for hardening coating deposition, the most common technologies used to restore and improve the performance properties of parts are gas-thermal spraying techniques, among which the cheapest and simplest method is electric arc spraying (EAS), whose current improvement is aimed at modifying and activating the spraying process. Such combined technologies do not require additional expensive equipment and operations, which predetermines a reduction in the cost of hardening processes.

Published: April 2021

Bu çalışmada René Girard’ın insan arzusunun kökenleri ve işleyişini tasarımladığı mimetik kuramı çerçevesinde yönetmen Tayfun Pirselimoğlu’nun Rıza (2007), Pus (2009), Saç (2010) ve Ben O Değilim (2013) filmlerindeki erkek karakterler çözümlenmiştir. Ele alınan filmlerin ortak özelliği erkek ana karakterlerin sosyo-ekonomik yapının en altında yuvalanan, hem maddi hem de kişiler arası ilişkiler açısından mağdur-kurban konumuna yerleştirilen ‘omega erkek’ler olmalarıdır. Pirselimoğlu’nun omega erkeklerinin duygudurumları Girard’ın mimetik kuramı ve bu kuram bağlamındaki ressentiment çerçevesinde incelenmiştir. Erilliğin yitimini deneyimleyen erkek karakterlerin hayata karşı ressentiment dolu oldukları sonucuna varılmıştır. Hâkimiyeti altında oldukları iktidarsızlık hissinden kendilerinden başka bir erkek olarak kurtulmak isterler ve kimliklerini ressentiment duygusuna göre oluştururlar.
