Dental trauma is one of the most important oral health problems during childhood. It occurs frequently in the school environment and it is extremely important that the professors have knowledge on the subject because the management taken after the accident, directly influences on the prognosis. Objective: The aim of this study was to evaluate the knowledge level about dental avulsion of teachers who work in the private and public elementary schools in the city of Curitiba (PR, Brazil). Material and methods: A questionnaire adapted from Mori et al. (2007) was applied, consisting of three parts, Part I: general demographic data; Part II: basic questions about the importance of emergency management, experience in dental avulsion and the management to be taken in an event of dental avulsion; Part III: Questions about dental avulsion. The chi-square test was used to identify differences in responses for different variables, with significance level of 5%. Results: A total of 98 teachers answered the questionnaire (54 private and 44 municipal schools). Most were women (66% in private and 95.5% in municipal schools), with professional experience between 6-10 years and a postgraduate degree (81.1% of teachers in private schools and 79.9% of teachers in municipal schools). The statistical analysis showed a significant difference between the groups in age and about the emergency procedure for dental avulsion. Conclusion: It can be concluded that knowledge by the elementary school teachers in cases of dental avulsion is inadequate.

Dental trauma affects mainly children, teenagers and young adults and the anterior teeth. In dental avulsion, the teeth are completely displaced out of the socket. This dentoalveolar lesion is that causing the most severe functional, esthetic, and psychologic damage to the patient. Objective: To evaluate the knowledge level of Dentistry undergraduates on tooth avulsion and verify whether the course period would be associated with the knowledge level. Material and methods: A questionnaire adapted from Fujita et al.. [5], was applied, consisting of three parts, Part 1: general demographic data; Part 2: questions about the experience in tooth trauma Part 3: knowledge about tooth avulsion. The questionnaire was applied to 706 Dentistry undergraduates from Positivo University (PR), in June, 2015. The chi-square test was used to identify differences in responses for different variables, with significance level of 5%. Results: Most of the students were at the age range from 16 to 20 years-old (47.1%), were female (74.7%), were not trained on first-aid care in cases of tooth trauma (73.9%), and never faced a case of tooth avulsion (68.8%). The course period was statistically and positively associated with the knowledge on dental avulsion. Conclusion: The evaluated Dentistry undergraduate students knew how to manage cases of tooth avulsion. Statistically significant differences occurred in relation to the course period and the knowledge on tooth avulsion.

Published: May 2022

Objective:

The objective of this study is to analyze and verify the main drug components
and targets of "Fuzi-Guizhi" in the treatment of osteoarthritis by using the network pharmacology
platform.

Methods:

The integrated pharmacology of "Fuzi-Guizhi" was analyzed by using the platform of
integrated pharmacology of traditional Chinese medicine to explore its mechanism in the treatment
of osteoarthritis. By establishing an arthritis model in vitro, the pharmacological effect of "aconitecassia
twigs" on articular cartilage was evaluated and conducted for molecular docking.

Results:

28 candidate active components, 37 compound targets, and 583 osteoarthritis-related potential
targets were screened, and 10 key target processes were screened in the protein interaction
network model. Enrichment analysis showed that the 10 core targets involved 958 GO biologic
function items and 76 KEGG signal pathways, which were mainly related to apoptosis and mitochondrial
functional metabolism. And "Fuzi-Guizhi" drug-containing serum inhibited the expression
of Caspase-3 mRNA and protein in chondrocytes and promoted the synthesis of ATP.

Conclusion:

Our research is preliminary that the mechanism of action of "Fuzi-Guizhi" may inhibit
chondrocyte degeneration by resisting mitochondrial apoptosis, and further experimental research
is required to determine.

Published: May 2022

The process of tissue damage, repair, and regeneration in the skeletal muscle
system involves complex inflammatory processes. Factors released in the inflammatory
microenvironment can affect the phenotypic changes of macrophages, thereby changing
the inflammatory process, making macrophages an important target for tissue repair
treatment. Mesenchymal stem cells exert anti-inflammatory effects by regulating immune
cells. In particular, exosomes secreted by mesenchymal stem cells have become a new
cell-free treatment strategy due to their low tumorigenicity and immunogenicity. This
article focuses on the mechanism of the effect of exosomes derived from mesenchymal
stem cells on the phenotype of macrophages after skeletal muscle system injury and
explores the possible mechanism of macrophages as potential therapeutic targets after
tissue injury.
QSAR Analysis, Molecular Docking and ADME Studies of Thiobarbituric
Acid Derivatives as Thymidine Phosphorylase Inhibitors: A Rational
Approach to Anticancer Drug Design by in silico Modelling
Authors: Rao Janhavi R. , Meher Pooja S. , Kumar Dileep
Published: May 2022

Background:

Thymidine Phosphorylase (TP) is an imperative target for cancer researchers. In
the current research, quantitative structure-activity relationship (QSAR) models were demonstrated to
identify new TP inhibitors.

Objective:

The main objective is to perform a QSAR study on a series of 19 derivatives of thiobarbituric
acid and new molecules designed and dock to check potency and efficacy for anticancer activity.

Methods:

Multiple linear regression analysis (MLR) was used to establish a two-dimensional quantitative
structure-activity relationship (2D-QSAR) with regression coefficient values of 0.9781, 0.9513, and
0.9819 for the training set (r2), leave-one-out (LOO) dependent internal regression (q2), and external test
set regression (r2 _pred), respectively. Three-dimensional quantitative structure-activity relationship (3DQSAR)
model, obtained by using the simulated annealing k nearest neighbour (SA-KNN) method (q2 =
0.7880). Newly designed molecules were subjected to docking studies with 7-deazaxanthine taken as
standard.

Results:

Molecular modelling, structure-based drug design and docking study analysis were performed.
The new chemical entities (NCE’s) designed, docked towards targeted receptor and show good results as
compared to the standard 7-deazaxanthine. It was found that these molecules bind similar amino acid
pocket regions as that of standard. Molecules bind at the active site of TP enzyme involving H bond interactions
with shorter distances showed greater affinity. At last, the oral bioavailability and toxic effect
were evaluated as absorption, distribution, metabolism, and elimination (ADME) studies by computational
means of the Qikprop tool of Schrodinger.

Conclusion:

One of the most successful and fast-increasing methodologies is molecular modelling. It not
only aids in the prediction of specific target compounds but also aids in the cost reduction of valuable
substances. QSAR and docking study was performed, and most of the molecules have shown good dock
scores. Based on these results, NCE’s for anticancer activity were successfully designed and analysed in
this research work which will be helpful for effective drug synthesis with less toxicity in the future.

Others:

2D QSAR model was generated by three methods, and the best one was selected for further
study. NCEs were planned based on descriptors such as topological, electrostatic, steric, and hydrophobic
substitutions around the core.

Lung cancer is a leading cause of cancer-related deaths globally. The availability of successful
anticancer agents in the market is limited, and the development process of a new drug molecule is slow
and difficult. The currently available commercial formulations are not sufficient to produce the desired
therapeutic response within a specific time limit. Therefore, there is an urgent need to develop novel
nanocarrier-based therapies to defeat the restrictions of existing therapeutics. Nanoparticles have been
investigated as novel formulations but are often inefficient in practical applications. However, several
unanswered questions and challenges exist in their clinical development; thus, a better understanding of
their influence on cancer biology, stability, and toxicity needs to be gained. This review discusses different
types of lung cancers as well as diagnostic approaches to lung cancer. The review also explores the
drug targeting mechanisms to cancer cells through nanoparticles and multi-drug resistance-associated
challenges in lung cancer therapy. Various nanocarrier systems that are safe and effective for drug delivery
in the treatment of lung cancer have been discussed. This communication will be of high relevance to
the biological, formulation, and translational scientists working in the field of cancer biology and drug
delivery.
Theranostics and Nanoparticular Approaches for the Treatment of Oral Squamous Cell Carcinoma
Authors: Bhattacharya Sankha
Published: May 2022

Oral squamous cell carcinoma (OSCC), one of the most common types of oral cancer, is a significant cause of morbidity and mortality worldwide. OSCC is typically treated with a multidisciplinary approach that includes surgery, chemotherapy, and radiation after a definitive oral cancer diagnosis. Conventional chemotherapy drugs, on the other hand, maybe ineffective and have a variety of side effects. Many techniques for treating and diagnosing various types of oral cancer have been proven and approved, while others are currently being researched in clinical trials. This mini review aimed to explain the current preclinical status of nano-based techniques for diagnosing and treating OSCC successfully. This mini compilation also highlights new theranostics approaches for treating squamous cell carcinoma (OSCC). Cancer biomarker detection has also been improved thanks to nanotechnology, which has made it faster and more sensitive. Various nanoparticles have been used as innovation drivers to overcome these constraints and enhance in-situ drug delivery.
Pyrrolopyridine and Isoindole as Potential Anticonvulsant Agents: Design,
Synthesis, and Pharmacological Evaluation
Authors: Davood Asghar , Taghizad Sepideh , Behbahaninia Khadijeh , Jahromy Mahsa Hadipour
Published: May 2022

Background and Objective:

Phthalimide, as the rigid form of ameltolide, exhibits a phenytoin-like profile of drug-receptor interaction and is active in the MES model and inactive in the PTZ model as an anti-epileptic agent. In this research, based on the isosteric replacement, we reported the design, preparation, and antiepileptic activity of 13 new analogs of pyrrolopyridine and isoindole.

Methods:

The designed compounds were prepared by condensing 3, 4-pyridine dicarboxylic anhy-dride, or 4-fluorophthalic anhydride with different aryl amines. MES and PTZ-induced seizure models were utilized to evaluate the antiepileptic effect of the prepared ligands.

Results:

It was found that the prepared ligands have significantly affected both tonic and clonic sei-zures. In tonic seizures, the prepared compounds decreased mortality to a significant extent, and in clonic seizures, they significantly showed better frequency and latency. Compounds 9, 12, and 13 were the most potent ligands than phenytoin.

Conclusion:

It is concluded that the best distance between two aryl parts is two bonds, and the sub-stitution of the nitro group at the meta position of the phenyl ring is better than the para position. Our research group has investigated this concept for designing newer compounds with better anti-convulsant activity.

Among Patients with Psychiatric Illnesses
Authors: Jin Jeff Wang , Nishikawa Millie , Ho Tiffany , Manohar Roja , Sanches Marsal , Cavalcanti Stefanie , Wu Hanjing
Published: May 2022

Introduction:

COVID-19 pandemic has been associated with increased rates of depression,
anxiety, and suicidal ideation. Individuals with mental illnesses are disproportionately
affected by additional complex health issues. This study aims to examine the knowledge and
impact of COVID-19 among patients with mental disorders at the Harris County Psychiatric
Center (HCPC).

Methods:

A retrospective review of surveys was conducted for patients with mental illness at
HCPC. Participants were surveyed on demographics, COVID-19 knowledge, and COVID-19
healthcare impact. The data were analyzed with SPSS 20 for Windows at a 0.05 significance
level.

Results:

A total of 46 patients were included in the study. We found that the patient population
with mental disorders has different methods of obtaining information regarding COVID-19 and
practices varying safety measures. To be precise, more women (52.2%) than men (21.7%)
learned about COVID-19 through family and friends (p=0.032). More Hispanic (21.4%) compared
to non-Hispanic (0%) patients learned about COVID-19 through resources from the
World Health Organization (WHO) (p=0.032). Fewer African American (AA) patients avoided
contact with people who were sick (39% vs. 81%) Caucasian (p=0.01) and (100%)
Asian/Native American/Pacific Islander [ANAPI] patients (p=0.04). We found more non-
Hispanic (50.0%) vs. Hispanic (7.1%) patients reported that their personal time (time outside of
work) was unchanged by COVID-19 (p=0.007). More Hispanic (57.1%) vs. non-Hispanic
(17.9%) patients reported increased time with family members (p=0.009). Compared to Hispanic
patients, more non-Hispanic patients reported unchanged difficulty scheduling appointments
(46.4% vs. 7.1%) (p=0.015), obtaining prescription (71.4% vs. 35.7%) (p=0.045), and
finding housing placement (53.6% vs. 21.4%) (p=0.047). Furthermore, more Caucasian compared
to AA patients reported more changes in how they feel (35.7% vs. 76.2%) (p=0.033),
anxiety (52.6% vs. 0%) (p=0.002), stress (47.4% vs. 7.7%) (p=0.024), and sadness (30% vs.
0%) (p=0.031). Finally, more ANAPI (67%) compared to AA patients (0%) reported increased
anxiety (p=0.025).

Conclusion:

Our findings suggest that African American patients report less knowledge of
COVID-19 prevention and less impact on their mental health by the pandemic compared to
other racial groups. Our findings suggest that African American patients may have limited
knowledge of COVID-19 prevention compared to other races, Caucasian and Asian/Native
American/Pacific Islander patients may have increased mood changes, and Hispanic patients
may be experiencing more healthcare inequality amidst the pandemic. However, further investigation
of the impending ramifications of the pandemic is warranted.
Photovoltaic Performance of Si and SiGe Surfaces Sonochemically Activated
in Dichloromethane
Authors: Korotchenkov Oleg , Shmid Volodymyr , Podolian Artem , Nadtochiy Andriy , Semen'ko Mykhailo
Published: May 2022

Aims:

To activate Si and SiGe surfaces by employing the sonochemical treatment at different operating frequencies in dichloromethane to improve the surface photovoltage signal.

Background:

To produce integrated electronic devices, one needs to achieve low surface and interface trap densities. In this respect, placing a passivating thin layer on Si and Ge surfaces, which saturates the electronic levels of traps and therefore affects the carrier recombination velocities at the surface, is of great interest.

Objective:

To demonstrate that the effectiveness of the treatment of Si and SiGe surfaces depends on the ultrasonic frequency used.

Methods:

Photovoltaic transients, electron microscopy, EDX spectroscopy.

Result:

The surface photovoltage (SPV) decay curves can be divided into rapid (τ_1) and slow (τ_2) components. The sonication effect on the SPV is different for the treatment done at about 25 and 400 kHz. The SPV signal in Si gradually increases with increasing lower-frequency sonication time, whereas the SPV enhancement on SiGe is somewhat smaller. Increasing the sonication time increases the amplitude of the τ_2 component in Si. In SiGe, the lower-frequency sonication quenches the τ_2 component yielding a nearly single-exponential decay form. This trend is even more pronounced at the higher-frequency sonication.

Conclusion:

The sonochemical treatments greatly intensify the formation of CxHy–Si and CxHy–Ge bonds on Si and Si1-xGex surfaces, resulting in increased SPV signals and prolonged SPV decay times. These results demonstrate that sonochemical treatment is a more effective technique to obtain stable highly passivated Si and Si1-xGex surfaces in comparison with wet chemical treatments in hydrocarbon solutions.

Authors: Jaffrin Lijetha C. , Srikanth G. Umarani
Published: May 2022

Background:

Disease diagnosis was a vital responsibility in healthcare. Machine learning classification methods would considerably improve the healthcare industry by providing a quick diagnosis of disease. Thus, time could be saved for doctors. Nearly 17.9 million people expire due to heart disease every year.

Objectives:

World Health Organization predicted that rate of death might increase by 24.5 million in 2030. Since heart illness was the major cause of death in comparison with other diseases today, it was the most challenging disease to diagnose.

Methods:

One of the reasons for death due to heart disease was due to the fact that risks were not identified in the earlier stage. Earlier diagnosis of disease was very much important. Machine Learning algorithms were used for predicting the prognosis of disease.

Results:

Here K-NN algorithm was used to predict the presence of heart disease in an individual. Thus, patients were classified as either positive or negative for heart disease and this model enhanced medical care and reduced the cost. This gave us significant knowledge that helps us to predict the patients with heart disease.

Conclusion:

The Python sci-kit library was used to implement this in Anaconda Navigator's Spyder Integrated Development Environment. Experiments revealed that technique worked well and was more accurate than before.

Published: May 2022

The objective of this study was to corroborate the dimensions of ecocentric governance: conflict between authorities and users, negotiation and agreement between the parties, and co-responsible self-regulation between the rulers and the ruled regarding energy and water resources and services. An exploratory, cross-sectional and psychometric study was carried out with a non-probabilistic selection of 100 officials and electricity and water service users. This study used the governance inventory, and the three preponderant factors were obtained: conflict, negotiation-consensus, and self-regulation-co-responsibility. The three factors refer to governance oriented towards resource conservation concerning the literature consulted. The third factor of self-regulation and co-responsibility suggests policies oriented toward the availability of energy and water resources. Empirical testing of the model in a scenario and a sample exposed to resource scarcity is recommended.

Published: May 2022

Para determinar la viabilidad de microinjertación en plantas de naranja Valencia y lima Tahití como un método de propagación masiva de plantas, diferentes pasos del proceso de microinjertación fueron evaluados. Las semillas de mandarina Cleopatra fueron establecidas in vitro en medio semisólido MS (Murashige y Skoog) con, o sin, GA3, para evaluar su efecto en el porcentaje y el tiempo de germinación, las plantas de naranja Valencia y lima Tahití fueron tratadas con 1 mg l-1 BAP o podadas manualmente para evaluar el efecto sobre la producción de brotes vegetativos, y el efecto de tres posiciones del ápice meristemático en la superficie del patrón decapitado, en el centro, en un lado y en un corte inclinado, sobre el porcentaje de éxito fue evaluado. Las repeticiones de todos los experimentos fueron distribuidas con un diseño completamente al azar, los datos de brotes vegetativos fueron analizados con ANAVA y los promedios separados con la prueba de Tukey. Los resultados evidenciaron que el GA3 no afectó el porcentaje y tiempo de germinación y la poda incrementó estadísticamente el número de brotes vegetativos. Los porcentajes de éxito de microinjertos de naranja Valencia (28%) y lima Tahití (14%) son consistentes con los resultados de otros estudios para recuperar plantas libres de enfermedades; sin embargo, para propagación masiva, se recomienda en futuros estudios considerar la evaluación de condiciones in vitro como aumento en la concentración de sacarosa, adaptación in vitro de los ápices meristemáticos y adición de auxina, entre otros.

NOVA IZBORNA REGULATIVA I PRINCIP REPREZENTATIVNOSTI: ZAKON O IZBORU NARODNIH POSLANIKA I ZAKON O LOKALNIM IZBORIMA
Authors: Pastor Balint
Published: May 2022

Predmet rada je analiza zakonodavnog okvira kojim se nakon dve decenije značajno menjaju izborna regulativa i principi legitimnog konstituisanja vlasti na republičkom i lokalnom nivou. Pravno-politikološkom analizom novih rešenja utvrđenih u Zakonu o izboru narodnih poslanika i Zakonu o lokalnim izborima, u svojevrsnom političkom intermecu neposredno po donošenju a pre primene na prvim narednim izborima, ukazaćemo na potencijalne ishode koji se mogu očekivati prevođenjem ideala pravne norme u stvarnost konkretnog biračkog mesta. U Dvanaestom sazivu Narodne skupštine inicirana su, sa stanovišta demokratske i institucionalne konsolidacije dva krucijalna pravno-politička procesa: referendumskim izajšnjavanjem građana potvrđen je Akt o promeni Ustava u delu o pravosuđu, a dva paralelna međupartijska dijaloga vođena pod pokroviteljstvom Narodne skupštine okončana su usvajanjem dokumenata iz kojih su proizašle promene važećeg izbornog modela. Cilj analize je identifikovanje uticaja nove regulative na do sada iskristalisanu izbornu praksu, sa fokusom na rešenja za koja očekujemo da će unaprediti princip reprezentativnosti a posebno političke reprezentacije nacionalnih manjina. U radu se ne bavimo kompletnim setom zakona od značaja za sprovođenje izbora, npr. o finansirnju političkih aktivnosti, spečavanju korupcije, izboru predsednika Republike Srbije, već se fokusiramo na ključne novine u izboru kolektivnih predstavničkih organa. Promene pravne regulative kojom se glasovi građana pretvaraju u poslanička i odbornička mesta ćemo kontekstualizirati u dvodecenijskoj perspektivi, koristeći različite istraživačke metode: istorijski i uporedni metod, kao i egzegetički, u smislu tumačenja različitih pravnih izvora, s tim da je posebna pažnja posvećena analizi, komentarima i tumačenjima određenih ustavnih, zakonskih i podzakonskih akata. Dodatna vrednost analize proizilazi i iz činjenice da metodološka saznanja tumačimo sa pozicije neposrednog učesnika u procesima izrade, usvajanja i implementacije propisa, u prethodnih 15 godina.

Posebnu pažnju posvetićemo uticaju rasnih i etničkih predrasuda na psihosocijalni razvoj dece, pripadnika romske nacionalne manjine sa analizom njihovog položaja u sistemu socijalne zaštite u Republici Srbiji. U zaključku ćemo ukazati na neophodnost promena sistema socijalne zaštite, unapređenja zakonodavnog okvira i usvajanje novih veština, metoda rada zaposlenih kao i neophodnost osnaživanja korisnika i uključivanja u nove programe rada, namenjene deci i porodicama iz marginalizovanih društvenih grupa.
POLUINTELEKTUALAC KAO FAKTOR KVARENJA DRŽAVNE VLASTI U TEORIJSKOJ MISLI SLOBODANA JOVANOVIĆA
Authors: Terzic Predrag
Published: May 2022

Predmet ovoga rada jeste poluintelektualac u naučnoj vizuri Slobodana Jovanovića. Jovanović je, u svojim delima, ovom karakternom tipu ličnosti posvećivao posebnu pažnju, uveravajući čitaoce u svu beskorisnost ovakvog tipa čoveka koji uporno stremi vlasti. Odsustvo moralnih osobina poluintelektualca, u interakciji s izazovima koje nameće državna vlast, neumitno dovodi do njegovog daljeg kvarenja. Otuda poluintelektualac ima svojstvo faktora koji širi svoje vrednosne stavove na druge. On ih čini ogoljenim karijeristima nespremnim za ispravne, već prijemčivim za nemoralne kompromise. Upoznavanje s ovakvom ličnošću, pronalaženje istorijskih primera i poređenje s aktuelnim društvenim prilikama ponovo aktuelizuje Slobodana Jovanovića u naučnoj javnosti. Istorijski vakuum, u kome je bio zabranjivan, kasnije se nastavlja suprotnim procesom, odnosno povećanim interesovanjem autora za Jovanovićevu naučnu misao. Ubrzano počinje period publikovanja knjiga i rasprava u kojima se javnost upoznaje s autentičnim momentima njegovog života i intelektualnog rada.
Cilj ovog rada se ogleda u originalnom prikazu stavova i mišljenja Slobodana Jovanovića o poluintelektualcu. Pored ovog tematskog obuhvata, u radu će biti razmatrana i šira teorijska misao Slobodana Jovanovića. Neselektivnim pristupom biće obuhvaćeni najvažniji izvori u kojima se pruža šira slika istorijskih događaja u čijem vrtlogu su važnu ulogu odigrali „poluintelektualniˮ pojedinci.
Rezultati rada se sastoje u iskazivanju sopstvenog zapažanja autora zasnovanog na originalnim zapisima Slobodana Jovanovića. U radu se eksplicitno zaključuje da njega, bez imalo preterivanja i pristrasnosti, smatramo nezaobilaznim autorom u teorijskom izučavanju fenomena državne vlasti. Pritom se izražena personifikacija državne vlasti ciljano zasniva na fenomenu poluintelektualca kao faktora njenog kvarenja.
POLOŽAJ BUGARSKE NACIONALNE MANJINE I PROCES PRISTUPANJA SRBIJE EVROPSKOJ UNIJI
Authors: Raduski Nada
Published: May 2022

U radu se na osnovu analize popisno-statističkih podataka proučava razvoj, položaj, socioekonomske i etnodemografske karakteristike pripadnika bugarske nacionalne manjine u Srbiji. Prateći i komparirajući rezultate sukcesivnih državnih popisa stanovništva, sagledani su depopulacioni trendovi u demografskom razvitku bugarske nacionalnosti, čiji se broj smanjio za preko tri puta od Drugog svetskog rata do danas, kao rezultat višedecenijskog opadanja stope fertiliteta, starenja stanovništva, migracija, etničke alternacije i drugih faktora. Pored brojnosti i prostornog razmeštaja, u radu se istražuje i starosna, obrazovna i ekonomska struktura stanovništva, kao važnog indikatora položaja i socio-kulturne razvijenosti bugarske nacionalnosti. Od značaja je i analiza popisnih rezultata o maternjem jeziku kao bitnom etnokulturnom obeležju za realizaciju određenih manjinskih prava u različitim sferama društvenog života. Drugi deo rada odnosi se na pravni i politički položaj pripadnika bugarske manjine kroz prizmu srpsko-bugarskih odnosa, imajući u vidu uticaj regulisanja statusa i poštovanja manjinskih prava na regionalnu saradnju i bilateralne dogovore Srbije i Bugarske. Istovremeno, to je i važan uslov za evropske integracije i pristupanje Srbije EU, što implicira da unapređenje položaja nacionalnih manjina i dobri odnosi sa susedima, posebno onima čiji pripadnici kao nacionalne manjine žive u Srbiji, predstavlja prioritet spoljne politike Srbije. Istraživanja sprovedena tokom poslednje decenije ukazuju da su stepen i oblici zagarantovanih ljudskih i manjinskih prava bugarske nacionalne manjine u Srbiji dobro postavljeni, uz moguće dodatno poboljšanje mehanizama za njihovo ostvarivanje.
Performance Analysis of Synchronous Reluctance Generator
Authors: Enemor C. G. , Idoniboyeobu D. C. , Braide S. L.
Published: May 2022

Abstract: The synchronous reluctance generators are a species of self-excited generators such as the induction generators. The self-excited synchronous reluctance generator (SynRG) has become a promising and viable replacement of self-excited induction generator because of the supply frequency dependence on the prime speed and not load. The self-excited synchronous reluctance generator has high reliability, low cost and robustness and capacity of variable speed operation. The aim of this research is to carry out performance analysis of shunt connected three-phase synchronous reluctance generator feeding an R-L load. The dynamic analysis is based on the classical d-q model where equations for electrical quantities were derived and implemented using a computer simulation tool, MATLAB®. The equations for steady state analysis were derived from the dynamic equations by setting all time variables to zero. The dynamic analysis was carried out on a 4-pole, speed of 1500 rpm with connected load at a fixed excitation capacitor value of 50uF for a 2.5kVA machine. Effect of excitation-capacitance variation and loadingconditions variation on the generated output voltage and frequency are presented and discussed. The load variations were done based on energy-current perturbation at a fixed power factor of 1.0. The load variations were done at several points and result shows that with the variations in the connected loads, the output frequency of the synchronous reluctance generator remains constant, which makes it a good alternative for induction generator. On the steady state analysis, it was discovered that on increasing the excitation capacitor, the terminal voltage increases as well as the output power. The result specifically revealed that when the capacitance increases from 25uF to 45uF, the terminal voltage and the output power increases from 200volts to 300volts; and 200watt to 1700watt. Therefore, it is recommended that to ensure machine excitation, the capacitor should not be reduced below a certain value. The study is beneficial for operation of an isolated power supply.

Automated Canteen Ordering System
Authors: Pandey Namrata , Sharma Shatakshi , Sharma Vidushi , Garg Tushar
Published: May 2022

Abstract: "Today, customers have little time to squander while waiting for a server to take their order at a cafeteria. A lot of clients come to the canteen during their lunch or recess, so they only have a short amount of time to eat before heading back to their workplaces or educational facilities. They can save time by ordering meals anytime they want without having to contact the waiter many times, thanks to this programme. With manual systems, you'll have to deal with a lot more files and manuals. It's a risky and time-consuming operation to save critical knowledge in files and manuals. The project includes a framework that shows how internet technology may be used gradually as abilities and confidence build as a progression from modifying materials to establishing an online environment. An e-menu card is available for end customers to utilize to read and pick food, and they may order food online by choosing the items they want. An E-menu card with your selections appears near the chef preparing your meal, so you can see what you've ordered right away. Android and iOS components coexist with a web application in this hybrid architecture. This system was built using PHP, CSS, JavaScript, MySQL, and HTML. Keywords: Canteen, Food, E-Commerce, WebApp, Self- Ordering

Stephen Harper, Michael Ignatieff, and Canada's Politics of Identity
Authors: Cody Howard
Published: May 2022

This article examines the visions of Stephen Harper and Michael Ignatieff. Using two identity models allows for an examination of contemporary Canadian politics and its future. Despite considerable differences in principles and goals and the political competition between the leaders of the Conservative and Liberal Parties, Canada's well-established two-party dynamic continues as it did prior to these leaders arriving on the political scene.
Immunize-Nation: Hollywood Contagion and the Biopolitics of the Canadian Nation-Building Project
Authors: Hodgins Peter
Published: May 2022

This exploratory essay investigates the fruitfulness of thinking about the intersection of fears of contagion and the construction of national cultural boundaries in relation to cultural nationalist discourse in general and to the specific Canadian nation-building project. It begins by tracing the rise of biopolitical discourses on contagion in the 19 th century, explores how these discourses took on a moral-cultural character with the rise of fears of "moral contagion" and "moral degeneracy" and demonstrates how the latter fears were central to early formulations of the cultural policy/media literacy apparatus in the Victorian period. It then investigates how this Victorian fear of cultural contagion continues to animate contemporary Canadian cultural policy discourse and, through a reading of some of the Heritage Minutes, contemporary Canadian cultural nationalist texts.
Constructing Black Canada
Authors: Crawford Charmaine , Flynn Karen , Gooden Amoaba
Published: May 2022

Black Canadian artists and scholars challenge racist and nationalist discourses of Canadian nationhood and citizenship that place First Nations people, people of African descent and other people of colour who are born in Canada and can claim Canadian nationality based on birth, as outsiders. By contesting the 'master narrative' of Canadian nationhood and by interrogating blackness within Canada, these artists and scholars claim "African Canada" as a convergence of multiple African diasporic voices, coming from different ethno, cultural, linguistic and national spaces, but together articulating a deliberately transgressive Canadianness.
"I'm Divorcing Because I Drank Lake Ontario": Marital Breakdown in Ghanaian Immigrant Families in Toronto
Authors: Donkor Martha
Published: May 2022

Much of the recent research on immigrant women in Canada has been focused on women from Asia perhaps due to the relatively large number of immigrants who have arrived in Canada in the past two decades from that part of the world. But it is also a fact that a significant minority of immigrants, including women, have come from the African Diaspora and made Canada their home. These African women have influenced and have in turn been influenced by Canadian culture. Yet there is relative dearth of information about them as women and as immigrants. The relative dearth of information about African immigrant women skews our understanding of the Black experience in Canada. This article fills a gap in the literature by examining the dynamics of gender roles and expectations in Ghanaian immigrant families.
'Outsider Within': Reflexivity and working with African Caribbean Immigrants in Qualitative Research
Authors: Gooden Amoaba , Hackett V. C. Rhonda
Published: May 2022

In trying to dismantle the hegemony of Western methodological frameworks, feminist and Black methodologies, which critique objectivity and value reciprocal engagement between researcher and subject, were used to explore research issues with African Caribbean subjects. In addition, using reflexivity, a process that is central to Black and feminist analytical frameworks, the authors interrogate and dispute the value of 'inherited western techniques' such as objectivity and the distancing of researcher from the 'researched'.
From Guardianism to Postmodernism: Historiography and the Interpretation of Canadian Political Culture
Authors: Pearce Colin D.
Published: May 2022

This article seeks to go some way toward shedding light on a certain dimension of Canadian intellectual history, specifically that dimension wherein the changing theoretical approaches to the phenomenon of Canadian political culture is the core subject matter.  Canadian political culture will be defined here as that collation of ideas, principles, thoughts and opinions which foster the establishment and continuation of a set of political structures and institutions which are liberal democratic at their foundations.  With this as a guiding definition the article examines the “paradigm shifts” in the study of English Canadian political culture that have taken place from the days of “The Makers of Canada,” through the ascendancy of the “Fragment Thesis,” to the more contemporary postmodernism of the “Liberal Order Framework.” The foundational assumption of the article is that debate and discussion about the Canadian experience in such fields as political philosophy, intellectual history, party ideology, constitutional structure, legislative procedure, executive power, judicial authority and local governance will tend to be shaped by the historiographical paradigm which has been most successful in making itself the accepted “orthodoxy” in the academic and intellectual circles of the period.
Expanding Social Justice: Exploring Connections Between Immigration and Indigeneity
Authors: Thomas Brian
Published: May 2022

Most discussions of group--‐differentiated disadvantage seek to explain its covert and overt nature through the experiences of dominant groups and their relations to subordinate groups.  This is a vertical approach to social injustice.  Instead of taking this approach, I take a horizontal approach that seeks to determine whether there are logics that produce disadvantage that are invisible to the vertical understandings of socially constructed group--‐ differentiated disadvantage.  To this end, I critically consider the relationships between disadvantaged groups by reflecting on the experiences of Black Canadians and Canadian Aboriginals.  Their experiences reveal the underbelly of Canadian multiculturalism and of discourses of membership and belonging.  I explore the ways in which these groups have potentially complex and conflicting modes of injustice that elicit potentially conflicting and complex prescriptions.  Recognizing this has the potential to facilitate a finer--‐grained sensitivity to the description and potential amelioration of group--‐differentiated disadvantage and to problematize discourses of membership and belonging in their instantiation in current Canadian practices, norms, and governing arrangements.
