Surgical treatment of oral leukoplakia using Er:YAG Laser – Case report
Authors: Duarte Fernando , Ramos Carina
Published: June 2022

Purpose: Leukoplakia is a clinical term indicating a white patch or plaque of oral mucosa
that cannot be rubbed off and cannot be characterized clinically as any other disease.
Leukoplakias may have similar clinical appearances, but have a considerable degree
of microscopic heterogeneity. Because leukoplakias may range microscopically from
benign hyperkeratosis to invasive squamous cell carcinomas, a biopsy is mandatory
to establish a definitive diagnosis.
Case Report: This paper will present a case report of a 63-year-old male patient,
caucasian, attended the Oral-Maxillofacial Surgery consultation at Clitrofa - Centro
Médico, Dentário e Cirúrgico, in Trofa - Portugal, to evaluate a white lesion in the
left jugal mucosa. The treatment plan was based on anatomopathological report
indicative of leukoplakia. It was decided to carry out surgical treatment of the lesion
using LightWalker® Er:YAG laser from Fotona. Local anaesthetic was infiltrated into the
soft tissue surrounding the lesion (Lidocaine/ Epinephrine 20 mg/ml + 0.0125 mg/ml
solution for injection EFG). The Er:YAG handpiece R16 was used, 3.6 J/cm2 Energy, 10
Hz Frequency, 13.8 W Power, LP Mode.
Conclusion: After a 12-month follow-up period, the patient is pain free and the lesion
has no signs of recurrence. Er:YAG laser may be considered a successful treatment
modality for oral leukoplakia.

Authors: D’Albis Giuseppe , D’Albis Vincenzo , Palma Micol , Plantamura Marianna , D’Orazio Fabrizio
Published: June 2022

Purpose: Hyaluronic acid (HA) has been used widely in medicine and is currently of particular interest to maxillofacial surgeons. Several applications have been introduced, including those in which HA is used as a scaffold for bone regeneration both alone and in combination with other grafting materials to enhance bone growth.
This review aims to analyze the available literature on the use of HA for maxillofacial bone augmentation for prosthetic-driven implant placement procedures. This article also aims to review the specific advantages, applications, and graft materials associated with HA use.
Materials and Methods: Medline and PubMed databases were searched for relevant reports published between January 2000 and December 2021.
Results and Discussion: Nine publications describing the use of HA to augment bone volume were identified.
Administration of HA facilitates surgical manipulation of the graft and promotes osteoblast activity that stimulates bone regeneration and repair.
Conclusion: Although further studies are needed, these findings are encouraging, as they suggest that HA might be used effectively together with additional graft materials in maxillofacial bone augmentation procedures.​

Authors: Putra Bima  R , Melkias Alvera , Melkias Alvera , Maridjo
Published: June 2022

Kondensor adalah alat yang berfungsi mendinginkan atau mengkondensasikan uap keluaran turbin  menjadi air. Air pendingin yang masuk ke dalam kondensor memliki nilai temperatur dan laju alir yang bervariasi, hal ini sangat berpengaruh terhadap kinerja kondensor. Kinerja kondensor dapat dilihat dari 2 faktor yaitu Cleanliness Factor dan Condensing Duty. Perhitungan kinerja kondensor menggunakan data aktual pada beban pembangkitan penuh yaitu 660 MW dan hanya diambil beberapa bulan saja, yaitu pada saat beban penuh di tahun 2019. Apabila ditinjau dari pengaruh temperatur air pendingin yang masuk ke dalam kondensor, nilai Cleanliness Factor tertinggi pada bulan Agustus 2019 yaitu 86,16% dan nilai dari Condensing Duty yaitu 721630 Kcal/hr. Sedangkan apabila ditinjau dari pengaruh laju alir air pendingin yang masuk ke dalam kondensor, nilai Cleanliness Factor tertinggi pada bulan Mei 2019 yaitu 83,54% dan nilai dari Condensing Duty yaitu 701673 Kcal/hr. Semakin rendah temperatur air pendingin yang masuk ke kondensor maka panas yang terkandung di dalam uap akan semakin banyak diserap oleh air pendingin. Dan Semakin tinggi nilai laju alir air pendingin yang masuk ke dalam kondensor maka panas yang terbawa oleh air pendingin pun akan semakin banyak, sehingga kinerja kondensor akan baik.

Authors: Sasono Teguh , Indriyani Indriyani
Published: June 2022

Salah satu upaya untuk mendukung ketahanan energi adalah memanfaatkan sumber daya alam sebagai sumber energi terbarukan. Biogas merupakan salah satu komponen sumber energi terbarukan yang penggunaan dan perkembangan teknologinya di Indonesia masih terus berjalan. Pada bagian hulu, pengembangan bahan baku dan proses produksi biogas masih terus berkembang. Di satu sisi, area hilir terkait tahapan pemurnian dan penampungan biogas hasil produksi masih terus dikaji. Pada pengguna biogas di tingkat rumah tangga, penampungan hasil produksi biogas masih mengalami kendala terkait tempat penampungan/storage gas yang umumnya terbuat dari plastic dan menyita ruang. Penelitian ini berupaya memampatan biogas ke dalam tabung LPG kapasitas 3 kg dengan menggunakan kompresor mobil, sehingga dapat memberikan kemudahan ketika pengguna akan memanfaatkannya dan dapat menghemat biaya transportasi dan penyimpanannya. Menimbang keamanan sistem, hasil kompresi ditetapkan sebesar 6,2 bar dengan hasil rata-rata sebesar 33,5 gram per tabung LPG. Kompresor bekerja pada keadaan dinamik dengan besarnya daya listrik yang digunakan sebanding dengan peningkatan tekanan dalam sistem kompresi, sebaliknya kecepatan motor berbanding terbalik terhadap daya listrik. Dari percobaan berbagai variasi kecepatan didapatkan besarnya rata-rata konsumsi energi listrik kompresor dan rata-rata konsumsi energi listrik total adalah 11,49 kJ dan 17,05 kJ per tabung LPG, sehingga indeks konsumsi energi listrik kompresor dan energi listrik total sebesar 0,3431 dan 0,5090 kJ/gram biogas. Dengan nilai HHV biogas sebesar 25.919,8 kJ/kg, maka besarnya total overhead energi untuk proses kompresi ini sebesar 0,5090 kJ energi listrik tiap 25,92 kJ biogas yang tersimpan dalam tabung atau rasionya sebesar 1,96%.
PENSTABIL TEGANGAN KELUARAN PEMBANGKIT LISTRIK TENAGA BAYU BERBASIS ARDUINO UNO
Authors: Mudawari Achmad
Published: June 2022

Pembangkit listrik tenaga Bayu (PLTB) merupakan salah satu pembangkit listrik energi terbarukan yang menjadi pilihan dalam program transisi energi nasional Indonesia menuju net-zero emission pada tahun 2060 (Paris Agreement 2015). Pembangkit ini untuk mendapatkan energi listriknya dilakukan dengan cara mengkonversi energi angin menjadi energi listrik. Pada proses konversi ini banyak menggunakan generator magnet permanen sehingga tegangan keluaran bevariasi sebanding dengan kecepatan angin yang berubah-ubah sehingga tidak sesuai dengan kebutuhan beban yang menghendaki tegangan konstan. Paper ini menyajikan stabilisasi tegangan tersebut dengan memanfaatkan teknologi konverter topologi Buck Boost Converter dengan kontrol berbasis Arduino Uno. Berdasarkan hasil pengujian yang dilakukan di laboratorium dengan menggunakan power supply variable, converter berfungsi dengan baik, yaitu mampu menghasilkan tegangan keluaran DC konstan sebesar 12 V DC sesuai setting yang telah ditentukan walaupun diberikan tegangan masukan yang berubah-ubah sebagaimana yang terjadi pada PLTB. Ini menunjukkan bahwa konverter yang diusulkan ini cocok untuk dipasang pada keluaran PLTB untuk mendapatkan tegangan keluaran yang konstan.

Published: June 2022

Material beton bertulang yang terkena suhu tinggi dapat mengalami penurunan kekuatan, sehingga bangunan gedung yang sudah terpapar suhu tinggi perlu untuk dievaluasi kembali. Tingkat penurunan kekuatan material beton bertulang dapat dipastikan dengan melakukan evaluasi mutu material dengan metode pengujian sampel secara non-destructive maupun destructive. Hasil evaluasi mutu material tersebut kemudian dijadikan sebagai data awal untuk melakukan analisis kekuatan elemen struktur dengan cara analisis numeris menggunakan software SAP2000 v.20.2. Berdasarkan hasil analisis secara numeris, diperoleh bahwa terdapat 79% kolom di lantai 1 dan 17% kolom di lantai 2 yang perlu diberi perkuatan. Kolom-kolom tersebut mengalami overstress, dimana nilai PMM ratio kolom tersebut diatas 0,95. Maka, berdasarkan hasil tersebut, kolom-kolom tersebut sudah tidak mampu menahan gaya-gaya yang akan bekerja pada bangunan gedung. Metode perkuatan yang diberikan pada elemen struktur kolom pada penelitian ini adalah metode concrete jacketing. Kolom diberi penambahan dimensi sebesar 100x100 mm2 dan berdasarkan hasil analisis secara analitis diperoleh bahwa kolom yang telah diberi perkuatan concrete jacketing mampu menahan gaya-gaya yang bekerja pada gedung.
Narratíva, kontextus, történelmi megismerés
Authors: Szécsi Gábor
Published: June 2022

We understand events in the world in terms of narratives which exploit the shared cognitive structure of our actions. We study narrative as one of linguistic phenomena which is challenged by the notion that human activity and experience are filled with meaning and that stories, rather than logical arguments or lawful formulations, are the vehicle by which that meaning is communicated. The aim of this article is to show, on the one hand, that the epistemology of historical understanding could have a lot of benefit from investigating the intense relation between the meaning, narrative and folk psychology. We deal, on the other hand, with some epistemological problems raised by the application of narrativist and contextualist method of historical analysis. In particular, we consider the questions that can be raised about the manner in which a historian can grasp past authors’ intentions, desires and beliefs.
Pipecolic acid in plants: biosynthesis, signalling, and role under stress
Authors: Nur Koc Fatma , Seckin Dinler Burcu
Published: June 2022

Plants protect themselves by developing defensive responses against various biotic and abiotic stress factors throughout their lives. As a result, they create a stress response called ʻsystemic acquired resistance’ (SAR) under pathogen infection. Pipecolic acid is one of the critical signalling molecules in regulating systemic acquired resistance, and it is a product of L-lysine metabolism in all organisms. It is synthesised not only by plants but also by microorganisms, animals and fungi. Many studies have been carried out to understand pipecolic acid’s biosynthesis, transport and role in plants under biotic stress. But recent studies report that pipecolic acid also functions as a stress response in plants under abiotic stress. This paper reviews the historical development of studies on pipecolic acid, its biosynthesis, and its function in plants under stress conditions and systemic acquired resistance.

The Turing Test, or a Misuse of Language when Ascribing Mental Qualities to Machines
Authors: Bremer Józef , Flasiński Mariusz
Published: June 2022

In this paper we discuss the views on the Turing test of four influential thinkers who belong to the tradition of analytic philosophy: Ludwig Wittgenstein, Noam Chomsky, Hilary Putnam and John Searle. Based on various beliefs about philosophical and/or linguistic matters, they arrive at different assessments of both the significance and suitability of the imitation game for the development of cognitive science and AI models. Nevertheless, they share a rejection of the idea that one can treat Turing test as a test for “machine thinking.” This seems to stem from a concern for the proper use of language —one that is a fundamental methodological commitment of analytic philosophy.

Aircraft are currently quite popular transportation, due to its ability to utilize air space as a flight path, so that it can be efficient in mileage. To support the safety of airplane passengers, every component on the aircraft must pass the test. One of them in the aircraft windshields that are prone to collisions with other objects. In accordance with the regulations in the Civil Aviation Safety Regulation (CASR) the windshield must withstand the impact load of a 0,91 kg bird. In this simulation, the material shape of the bird uses the EOS Tabular type. For modeling windshields, frame¸ gaskets and birds use a general method for solid materials, namely the Lagrangian method. Rubber used as gasket material with mooney rivlin for modeling material behavior. the polymethyl methacrylate and aluminum alloy 7075 T6 material is used in the windshield and frame. Numerical modeling is validated using analytical results. The gasket thickness of 2 mm produces the most optimum energy absorption. The use of gaskets on the windshield does not have a significant effect on the windshield because the gasket on average is only able to absorb 5% of the total energy absorbed by all windshield parts. The collision parameter that produces the greatest failure occurs at a speed of 87,5 m/s with -15o angle. The area that is most prone to material failure is in the area of the upper bolt hole.

A Motion Flow Guided MicroNet Framework for Micro Expression Recognition
Authors: Verma Monu , Vipparthi Santosh kumar , Singh Girdhari
Published: June 2022

 The micro-expression recognition (MER) has gained high attention in real-world applications: human-computer interaction, depression estimation, virtual reality, etc. However, MER systems still face difficulty in capturing the subtle information with spatial appearance of micro expressions. In this paper, an efficient and robust motion flow-guided MicroNet framework is proposed for MER. The proposed MicroNet consists: motion flow generator (MFGen) and avalanche feature (AFeat) block. The MFGen is introduced to extract the temporal changes at expressive regions by analyzing the motion intensity of pixels among the frames. Further, the AFeat block is designed to capture the spatiotemporal feature using a multi-lateral complementary feature (MCFeat) block. The MCFeat block is proposed to elicit the coarse and deep edge responses from multi-scale receptive fields. Thus, the proposed MicroNet estimates not only momentary variations but also learns affective appearance features of micro expressions. Furthermore, the efficacy of the proposed MicroNet is examined by conducting experiments on two experimental setups using six comprehensive datasets: CASME-I, CASME-II, CAS(ME)2, SAMM, SMIC and COMPOSITE, with two validation schemes: leave-one-subject-out and cross-domain to demonstrate the generalization capacity and robustness of the proposed framework. Also, eight ablation experiments have been executed to validate each module’s role in the MicroNet framework.
Dynamic Musculoskeletal Simulation of a Passive Exoskeleton for Simulating Contracture
Authors: Bajpai Rishabh , Joshi Deepak
Published: June 2022

Gait assessment scores are used for quantifying the abnormalities in the gait. Evaluation of the performance of these scores is a must for their clinical acceptance. However, current methods of assessing the performance of the gait assessment scores for clinically relevant gait abnormalities are prone to error. For example, values of intra-observer reliability, inter-observer reliability and sensitivity calculated for a gait assessment score change with the population of patients and observers. Therefore, there is a need for a methodology for replicating musculoskeletal deformations such as contracture in healthy individuals for objectively evaluating the performance of gait assessment scores with variable severity of musculoskeletal deformations. In this study, a series of dynamic musculoskeletal simulations are performed to simulate and verify a mathematical model of a passive exoskeleton for simulating contractures. The proposed model achieved a root mean square error of 1.864° and a correlation of coefficient of 0.984 while testing on five unique combinations of linear and non-linear torques and seven degrees of severity of hamstring contracture. To understand the tolerance of the proposed model to environmental noises, its performance is also tested at various perturbations. The results indicate that a passive exoskeleton attached to an unimpaired musculoskeletal model can accurately simulate the contracture of the targeted muscles.
Paradigms of US global strategy — concepts globalization and global instability
Authors: Senchenko Mykola
Published: June 2022

Analyzing the processes and events taking place in the world today, one gets the strong impression that the Washington "sages" — the main directors of modern world development — have decided to abandon the unsuccessful and boring play in order to stage a new one.

It is about the obsolescence of the concept of globalization, so actively discussed in the recent past, and its replacement by the concept of global instability, which is in fact a return to Hegel's dialectic, which states: "all historical events are the result of conflict between opposing forces" [1].

It is the antagonistic contradictions that have led to the strengthening of American dominance in the world as a result of the shaking of stable political structures, the creation of zones of numerous conflicts and world governance through the interaction of opposites in which conflicting forces are irreconcilable. This is achieved by manipulating opposing political forces.

Authors: Khailo Alona
Published: June 2022

The author conducts a complex study of reviews from the columns of the magazine "Knyhar" which dedicated to published collections of folk songs (included both author's poetry and folk texts) and a separate editions of folk songs. In particular, the study includes the following issues of the "Knyhar": 1, 3, 4, 6, 8, 12—13, 16, 20, 21. Previous studies are briefly analyzed, namely a number of works which had been found during the work on the article and cover broader topics such as history, historiography, bibliography, bibliography, literary studies and publishing. Theoretical analysis of the review as a genre is carried out and the reviews of the "Knyhar" in general are made. The author examines the actual texts of reviews on the topic and carried out their analytical review. In addition, the names and personalities, the scope of activities of reviewers were identified. The names and field of activity of reviewers who participated in the critical review and evaluation of collections of song folklore (specialists in the field of musicology, folklore, literature and pedagogy) were identified. Approaches to the evaluation of a peer-reviewed work are clarified, as they depend on the direction of the publication itself, as well as on the field of interest of the reviewer. The approaches of scientists to the critical evaluation of publications are analyzed and systematized. The researcher also investigates which aspects of printed works were of interest to the authors of the reviews.
Cossack roots of our independence: we think about the past for the future of the future
Authors: Doiar Larуsa
Published: June 2022

The presented article raises the problem of Ukrainian statehood, which is always relevant and emphasized on the eve of the 30th anniversary, in the context of its initial — Cossack — segment. The article is devoted to the history of state formation, initiated and generated by the Zaporozhian (Sich) and Ukrainian urban (Hetmanate) Cossacks. The author's classification of the Cossack period of national history according to such features as chronology of liberation struggles, character of confrontation and struggle, attributive registration of statehood (in particular, institutionalization of branches of state power and their documentary fixation in legislative (constitutional) acts is noted in the work. The author captures the stages of Cossack statehood (Christian republic-protostate, monarchical hetman state, autonomous Hetmanate as part of tsarist Russia), arguing the obvious regression in its development. Avoiding the possible politicization of the scientific problem, the author deliberately chose retrocontent as the primary source for this study, namely, the works of the most authoritative, without exaggeration, legendary Ukrainian historians of the end of the XIX — first third of the last century, such as: M. Hrushevsky, M. Drahomanov, B. Grinchenko, G. Khotkevych, L. Tsehelsky, G. Kovalenko (Hetmanets), P. Klepatsky, V. Riznychenko and others. The latter cannot be suspected of "treacherous" sentiments, although they cite harsh critical maxims, presenting the past and its participants comprehensively and objectively, while not hiding their personal feelings. An interesting circumstance of their mutual view is the extremely negative attitude towards I. Mazepa, a figure glorified in modern Ukraine, who became the foundation of the education of Ukrainian society. The highlight of the study is the citation of the "Constitution of Kostya Gordienko", older than the legal document of P. Orlyk and quoted in the work of L. Tsegelsky "Russia-Ukraine and Moscow-Russia".

The industrial application of the spheroidization process using high-temperature plasma is regarded as a good method for the conversion of irregularly shaped particles into a spherica shape. High temperature and controlled plasma conditions are required to obtain satisfactory results. Given this, a 3D model was used to simulate heat transfer from a source term to titanium-alloy particles using ANSYS Fluent software. Such models consider the effects of particle treatment on thermodynamic and transport properties of the plasma. This present study aims to investigate the impact of heat transfer on the particles and the effect of radiation energy loss on the particles, using numerical analysis. The results showed that the operating condition such mass flow was inversely proportional to the rate of heat transfer between plasma particles and the characteristics of the plasma gas, which was due to significant variation in radiation energy losses.

Background: Covid-19 vaccine is an immunization method used to reduce coronavirus incidence but lately caused life-threatening events such as thrombosis with thrombocytopenia syndrome. Methods: This is a case-control study conducted at Shendi town to evaluate platelet parameters and fibrinogen levels in vaccinated healthy individuals With Covid-19 vaccines between Augusts to November 2021. A total of (100) vaccinated healthy individual With the Covid-19 vaccine was enrolled in the study as test groups, compared with (50) healthy volunteers as a control group. Venous blood samples were transferred into Trisodium citrate and EDTA anticoagulant. Data was collected using a questionnaire and the (SPSS) version (22) program was used for data analysis. Results: The study revealed that the vaccinated healthy individuals were; (50%) male and (50%) female. The platelets parameter and fibrinogen indicated the mean values of platelets count, mean platelets volume, platelets distribution width, platelet crit, and fibrinogen, in Janssen vaccine groups, were (251.14 109\L), (8.39 fl), (15.6), (0.203%), and (158 mg\dl) respectively. The results study revealed the mean of PLT, MPV, PDW, PCT, and Fibrinogen, in Astrazeneca vaccine groups, were (272.08 109\L), (8.13fl), (15.56), (0.2211%), (159 mg/dl) respectively. Also explained the mean of PLT, MPV, PDW, PCT and Fibrinogen, in Astrazeneca vaccine groups were (272.08 109\L), (8.13fl), (15.56), (0.2211%), (159 mg\dl) respectively and in Janssen vaccine groups the mean values of PLT, MPV, PDW, PCT, Fibrinogen were ( 251.14 109\L), (8.39fl), (15.63), (0.2034%), (158 mg\dl) respectively. Conclusions: Covid-19 vaccines are responsible for significant changes in fibrinogen level in both AstraZeneca and Janssen vaccine groups.
Prevalence and Risk Factors of Work Related Musculo Skeletal Disorders (WRMSD’s) Among Doctors - A Cross Sectional Study
Authors: M Biju Azariah , Babu Geethu
Published: June 2022

Work related musculoskeletal disorders (WRMSDs) have not only shown to impact the physical and pschycological comfort of the employee but also deteriorate the prospects of any production or service sector. The prevalence of WRMSDs, though studied extensively in various sectors, has been understudied in health sector, especially among doctors. This study which evaluated the prevalence and risk factors of these disorders among fifty cancer treating Radiation Oncologist at a Tertiary Care Cancer Centre in India had exposed out an alarming 68% prevalence of these disorders in the study population, with neck pain being the commonest site of these Muscloskeletal Disorders (MSDs). Several factors which could impact the development of MSDs were analysed. This higher incidence of MSDs is presumed to be because of extreme physical and mental stress of working in a high volume cancer care centre, persistent unhealthy postures during work, inadequate micropauses between works and uncomfortable working atmosphere. Adequate physician patient ratio, restricting the patient load, providing good physician friendly working environment and adequate mandatory breaks might significantly reduce the incidence of these disorders and can prevent the sagging of health care delivery.

Creutzfeldt-Jakob disease or subacute spongiform encephalopathy is a rare prion encephalopathy with a long incubation period and fatal outcome without remission. In this summary, we report a case of sporadic Creutzfeldt-Jakob disease consolidates by positive income CSF analysis of the 14.3.3 protein. This patient study report presents a 54 years old Moroccan male patient with no underlying disease. Whose history of the disease goes back to 04 months, by the admission at the department of psychiatry for the quickly progressive installation of a depressive syndrome, with behavioral disorders made up of anxiety and aggression towards, associated with a decline in visual acuity that the patient reported as very annoying and disabling, while the ophthalmologic examination without abnormalities, and the patient was able to walk alone and avoids obstacles while walking. With a strictly normal brain MRI, treatment by antidepressants and neuroleptics has been prescribed. The evolution was marked 3 months later by the appearance of significant memory disorders associated with hallucinations, impaired walking, and myoclonus in the upper limbs which are exerted by sounds in the arms and legs. A new brain MRI performed showed bilateral frontal and occipital cortical high signal, a visual evoked potential demonstrated a decrease in the activity of the visual pathways with alteration of the central macular vision, the electroencephalogram (EEG) revealed a slowing of the background activity with periodic activity and rapid rhythmicity, the study of Cerebrospinal fluid (CSF) was without abnormalities regarding CSF value of proteins and glucose but the dosage of the protein 14.3.3 came back positive. Following these clinical, biological, radiological, and electrophysiological elements, the diagnosis of sporadic Creutzfeldt-Jakob disease (sCJD) was retained.
