Soft tissue lesion of the ear canal – Now you see it, now you don’t
Authors: Wong Kim Yew Richard , Al-Hadeethi Yahia Faik Hussein
Published: February 2021

Spontaneous herniation of the temporomandibular joint along a bony defect in the external auditory canal is an uncommon condition that may lead to otologic symptoms. A 43-year-old gentleman presented with otalgia and an external auditory canal soft tissue lesion, which flattens upon opening of the jaw. Computed tomography scan of the temporal region confirmed the presence of a soft tissue lesion that herniated through an external auditory canal wall defect. This condition should be included in the differential diagnoses of an external auditory canal mass, despite infrequently encountered. It is important to inspect the external auditory canal during movement of the jaw when a soft tissue lesion is noted, so as not to miss this diagnosis.
Numerical modeling of energy efficient solutions of foundry class electric arc furnaces.
Authors:   State Institution of Higher Education «Donetsk National Technical University, S. TIMOSHENKO , E. NIEMTSEV
Published: February 2021

Research is aimed at reducing the energy loss of foundry class arc furnace, which belongs to energy-consuming units with a non-rhythmic work schedule, and characterizes by low energy efficiency. Method of numerical modeling substantiates the concept of furnace modernization, which consists in rising the specific electric power by lowering the capacity at constant productivity, relative increasing of the liquid bath depth, reducing accumulation heat loss by refractory lining through introduction of energy saving water-cooled elements with a spatial structure in its local areas and intensification of heat and mass transfer processes in the "deep" bath with pneumatic stirring. It is determined that for arc furnaces with capacity of 12 and 6 tons, working in one shift, it is rational to reduce the capacity to 6 and 3 tons respectively and the bath shape factor (ratio of diameter to depth) from 5 to 2.5; installation of water-cooled elements in central endurance critical part of the roof and upper parts of the walls with coverage of 0.20-0.32 and 0.5-0.8 of working surface, respectively. With regard to the economy of heating systems, the expansion of the cooling system for the economic efficiency of modernization is 12 tons of chipboard with magnesite lining, so in the small world, dinas lining. For 6 t furnaces of water-cooling elements at the same time the magnesite lining is also effective, the protector is more cheap acidic lining (dinas), however, the water-cooling elements require a larger analogue. With available supply transformer, the specific power increases to 1 MVA/t, which will allow, due to intensification of heat and mass transfer processes, provide quantitative and qualitative indicators of production with lower, compared to the basic unit, heat loss. The implementation of proposed solutions will reduce energy consumption by 75 kWh/t and, taking into account the cost of refractory, provide an economic effect of 320-515 UAH/t
On Primes of the Form 2x-q (where q is a prime less than or equal to x) and the Product of the Distinct Prime Divisors of an Integer (Revised): A Function Approach to Proving the Goldbach Conjecture by Mathematical Induction
Authors: Kamalu Chukwunyere
Published: February 2021

This paper is really an attempt to solve the age-old problem of the Goldbach Conjecture, by restating it in terms of primes of the form 2x-q (where q is a prime less than or equal to x). Restating the problem merely requires us to ask the question: Does a prime of form 2x-q lie in the interval [x, 2x]? We begin by introducing the product, m, of numbers of the form 2x-q. Using the geometric series, an upper bound is estimated for the function m. Next, we prove a theorem that states every even number, 2x, that violates Goldbach’s Conjecture must satisfy an inequality involving a simple multiplicative function defined as the product, ρ(m), of the distinct prime divisors of m. A proof of the Goldbach Conjecture is then evident by contradiction as a corollary to the proof of the inequality.
Formation conditions and evolution of oil and gas source strata of the Laptev sea shelf ore and gas province
Authors: Kerimov V. Yu. , Shcherbina Yu. V. , Ivanov A. A.
Published: February 2021

Introduction. To date, no unified well-established concepts have been developed regarding the oil and gas geological zoning of the Laptev Sea shelf, as well as other seas of the Eastern Arctic. Different groups of researchers define this region either as an independently promising oil and gas region [7, 8], or as a potential oil and gas basin [1].

Aim. To construct spatio-temporal digital models of sedimentary basins and hydrocarbon systems for the main horizons of oil and gas source rocks. A detailed analysis of information on oil and gas content, the gas chemical study of sediments, the characteristics of the component composition and thermal regime of the Laptev sea shelf water area raises the question on the conditions for the formation and evolution of oil and gas source strata within the studied promising oil and gas province. The conducted research made it possible to study the regional trends in oil and gas content, the features of the sedimentary cover formation and the development of hydrocarbon systems in the area under study.

Materials and methods. The materials of production reports obtained for individual large objects in the water area were the source of initial information. The basin analysis was based on a model developed by Equinor specialists (Somme et al., 2018) [14—17], covering the time period from the Triassic to Paleogene inclusive and taking into account the plate-tectonic reconstructions. The resulting model included four main sedimentary complexes: pre-Aptian, Apt-Upper Cretaceous, Paleogene, and Neogene-Quaternary.

Results. The calculation of numerical models was carried out in two versions with different types of kerogen from the oil and gas source strata corresponding to humic and sapropel organic matter. The results obtained indicated that the key factor controlling the development of hydrocarbon systems was the sinking rate of the basins and the thickness of formed overburden complexes, as well as the geothermal field of the Laptev Sea.

Conclusion. The analysis of the results obtained allowed the most promising research objects to be identified. The main foci of hydrocarbon generation in the Paleogene and Neogene complexes and the areas of the most probable accumulation were determined. Significant hydrocarbon potential is expected in the Paleogene clinoforms of the Eastern Arctic.

Lithological characteristics and formation conditions of lower jurassic limestones occuring in the Patil mountain (south-western Crimea)
Authors: Agafonova G. V. , Andruhovich A. O. , Komarov V. N. , Rakhimova E. V. , Turov A. V.
Published: February 2021

Background. In this article, we investigate an outcrop of the Lower Jurassic limestones of the Eskiorda suite located on the northern slope of the Bodrak River basin in the south-western Crimea.

Aim. The outcrop under study is mentioned in the majority of monographs devoted to the geology of the Crimean Mountains. Although the palaeontology of this assemblage has been sufficiently studied, its lithological aspects require elucidation. We carried out a series of lithological studies to identify the composition, structure and formation conditions of this limestone assemblage.

Materials and methods. A macroscopic study of the outcrop was conducted followed by a detailed lithological study of collected limestone samples using a polarising microscope.

Results. The conducted microscopic analysis revealed three structural types: organogenic-detrital, detrital and oolitic-organogenic-detrital limestones. The dominant component in the composition was fragments of echinoderms, mainly crinoids. Among other components were — in descending order — brachiopods, gastropods, foraminifera, remains of green algae, sponges, ostracods, ammonites and radiolarians, whose total content did not exceed 10%. Cinoid fragments were round to a various degree. The limestone fragments (intraclasts) were characterised by organogenic-clastic and pelitomorphic structures with an organogenic sludge, occasionally containing fine-sandy and silty quartz admixtures. Oolitic-organogenic-detrital limestones were almost entirely composed of crinoid fragments, some of which represented oolith cores. A specific feature of the limestones under study is their significant hardness resulting from the cementation of the structural components predominantly with crustification cement of several generations.

Conclusions. The obtained results allowed us to draw conclusions about the formation conditions of the studied rocks. The limestones were formed in shallow water under the action of waves on the sediment in zones of constant currents. The hydrodynamic action on the sediment led to the formation of intraclasts. The early lithification of the sediment contributed to the formation of a hard seabed, on which subsequent generations of echinoderms settled, lived and died, forming an accumulative carbonate body.
POSITIONING MALAYSIA IN THE REALM OF GLOBAL UNCERTAINTY: ANALYSING ITS CONCERN AND STRUGGLES OF PAKATAN HARAPAN GOVERNMENT
Authors: Idris Zokhri
Published: February 2021

The US-China trade war juggernaut has shackled the political, economic and social landscapes of nation states globally at varying degrees. While trade talks are still ongoing and President Trump has hinted at the possibility of an interim agreement, the prospects of both sides agreeing on a comprehensive US-China trade deal in the near-term remains cloudy. Several factors place Malaysia to be in interesting position. First, Malaysia has and is still a geopolitically important trading route. Being an integral component to the production house of the global supply chain of finished products, its economy depends highly on the movement of goods and global currency. Furthermore, Malaysia is dominantly attached to the Chinese economy. It implies the fact that trade protectionism in the U.S. has resulted into a slowdown of Chinese growth, which eventually will have a domino effect on the Malaysian economy. Worsening the situation, COVID-19 shuts down major operations in the world, disrupting global supply and chain. Countries react towards inward strategies, alleviating national security and domestic economies at the expense of globalization process. While we have passed the first wave and re-generating world economy, global economy trajectory is still deemed ambiguous. China, as major hub for manufacturing, supply and chain is affected and struggles to increase its GDP from 6.1% end of 2019. In surfacing this uncertainty, the seventh Prime Minister Dr. Mahathir Mohammed lays out three frameworks that guide the conduct of Malaysian foreign policy. First, Malaysia remains as an active discussant at all platforms which Kuala Lumpur is already a member. Second, it will communicate its influence towards any decision-making processes in platforms which Kuala Lumpur is not a member. Third, Kuala Lumpur will align with the increasing penetration of Industrial Revolution 4.0 and the blue economy. Should this be the way from 2020 onwards or new strategies ought to be crafted? What are the contemporary indicators Kuala Lumpur having to consider? Eventually, what could be the ultimate message Malaysia in positioning herself, which described her synergies and potential in near future? These questions will guide to examine the feasibility of Change in Continuity as a conduct of Malaysian foreign policy in near future.

Published: February 2021

Budget deficit is one of the most significant macroeconomic issues which have been debated both in the academic and political arena since 1970s. This study aims to explore the current position of government budget deficit, its trends, and sources of budget deficit financing in Bangladesh covering the periods of 1980 to 2018. Secondary data has been used which is collected from Bangladesh Economic Review and World Bank. Data has been analyzed through descriptive methods. The Government financing budget deficit from two sources like domestic and foreign sources. The study finds that Government finances most of its budget deficit from the domestic sources than foreign sources especially from non-banks sources due to the increase in the net sale of national savings certificates while borrowing from bank sources is on the decline. Along with the effective measures of generating more internal resources, the government should also focus on other areas to reduce the budget deficit. The government should be taken proper steps to make progressively investable resources and generate a fund for financing the non-development spending for reducing the reliance on debt that can guarantee more distribution on the development sector.

Published: February 2021

The administration of justice on the basis of a fair trial is not an easy task, as both parties to the dispute are usually certain of their rightness, which they are trying to prove to the court. If one of these parties is a state or its bodies, the judiciary can become a dangerous tool to influence any process in society. Specific cases against
Ukraine show that high-ranking officials of all periods of power did not neglect the possibility of influencing the outcome of the case, pursuing goals not related to the administration of justice. The influence of the European Convention and the case law of the European Court of Human Rights has become decisive for Ukraine in the formation of a separate procedure for the administration of justice: administrative proceedings. Some aspects of its functioning are investigated in this work, in particular, the preconditions for the differentiation of administrative proceedings in Ukraine, the problem of defining the concept of the authorities and the state as a party to the case, the implementation of the right to a fair trial in administrative proceedings, access to court and the principle of the equality of parties; oral and open administrative proceedings; adversarial proceedings and the right of the court to establish the circumstances of the administrative case.

Цель. Для различных типов материалов изучить зависимость величины коэффициента дымообразования, определенной по стандартизированной методике, от доли сгоревшего материала и длины волны оптического излучения, проходящего через задымленную среду при их горении, и разработать на основе полученных данных скорректированные методики определения величин коэффициента дымообразования и удельного выхода дыма.

Методы. Значения показателя ослабления оптического излучения и доли сгоревшего материала при определении его коэффициента дымообразования определялись экспериментально. Изменение времени потери видимости при пожаре определялось расчетным методом.

Результаты. Экспериментально получены величины показателя ослабления оптического излучения, проходящего через задымленную среду при горении 10 типов материалов, и определены значения коэффициента дымообразования, учитывающие долю массы сгоревшего материала и длину волны излучения. Установлена экспериментальная зависимость изменения показателя ослабления оптического излучения в диапазоне длин волн (400–1100) нм при горении 10 типов материалов. Экспериментально определены значения удельного выхода дыма 10 типов материалов. Показано, что при отсутствии учета доли массы сгоревшего материала и длины волны зондирующего излучения значение коэффициента дымоообразования уменьшается до 2,6 раза, что приводит к увеличению расчетного значения времени наступления потери видимости при пожаре до 30 %. Скорректирована методика определения удельного выхода дыма при горении материалов.

Область применения исследований. Результаты исследования могут быть применены при моделировании пожаров и оценке уровня пожарной безопасности людей.

Indonesia is an archipelagic country. One can be found as the indigenous specimen alongside the coastal part of the country is the Sumatran Krill (SK), commonly known as ‘Udang Saih’ which can be found in Padang, West Sumatra. While the local people use it to make traditional condiment (like shrimp paste), the krill itself could be extracted to create more valuable products since it contains various important unsaturated fatty acids such as omega-3, omega-6, omega-7, and omega-9 and the powerful antioxidant carotenoid named astaxanthin. Astaxanthin as the main carotenoid in SK extract offers several health benefits such as anti-inflammatory properties, support immune system modulation, as well as maintaining brain, cardiovascular, and eye health. In this study, we aim to incorporate the SK extract into an instant noodle product. In addition, we used the composite flours consisted of high-protein wheat flour (WF) and yellow sweet potato flour (YSPF) which are rich in β-Carotene as a vitamin A precursor, to further enhance its eye health property. The instant noodle prototype (M2) was made from a mixture of YSPF (40 g), WF (40 g), super-concentrated astaxanthin in sunflower oil (8 mL), and super-concentrated astaxanthin (2.4 mL) had the highest score of sensory attributes. This instant noodle prototype was claimed to contain astaxanthin, essential fatty acids, and provitamin A carotenoid as well as low in gluten content. Therefore, this instant noodle prototype is believed to increase the health benefits and can be well accepted in society.

AbstrakKebutuhan energi listrik semakin hari semakin meningkat. Bahan bakar fosil seperti batu bara, gas dan minyak bumi merupakan energi yang tidak dapat diperbaharui serta memiliki jumlah yang terbatas. Hal itu mendorong berkembangnya energi terbarukan sebagai sumber energi alternatif pembangkit tenaga listrik. Salah satu sumber energi terbarukan adalah sel surya atau photovoltaic (PV) yang memanfaatkan energicahaya matahari. Permasalahan dalam penggunaan PV saat ini adalah efisiensinya yang masih rendah dengan biaya yang tinggi. Efisiensi PV dapat ditingkatkan menggunakan metode Maximum Power Point Tracking (MPPT) untuk menghasilkan daya maksimum PV. Penelitian tentang MPPT dilakukan dengan berbagai metode pada aplikasi sistem PV menggunakan Buckboost converter. Penelitian ini menggunakan Adaptive Neuro Fuzzy Inference System (ANFIS) sebagai MPPT untuk menjejak titik daya maksimum.Hasil penelitian menunjukkan bahwa ANFIS mampu bekerja sebagai MPPT dan memiliki respon yang baik dalam menjejak titik daya maksimum diberbagai kondisi iradiasi dan temperatur. PV menghasilkan daya maksimum saat temeperatur tetap dengan variasi iradiasi 400 W/m2, 600 W/m2, 800 W/m2 dan 1000 W/m2. PV juga menghasilkan daya maksimum saat iradiasi tetap dengan variasi temperatur 15oC, 25 oC dan 40 oC.Kata Kunci: ANFIS, Buckboost, MPPT, Photovoltaic.AbstractThe need for electric energy is increasing every day.

Kemacetan merupakan permasalahan yang sering terjadi dalam masalah transportasi. Persimpangan Juandamerupakan salah satu persimpangan yang seringkali mengalami kemacetan. Adapun penyebab kemacetanmuncul dari banyak hal antara lain adanya hambatan samping, tidak terdapatnya marka hingga traffic lightyang bekerja kurang optimal. Berdasarkan dari hasil survey awal diketahui bahwa lama lampu hijau padamasing-masing pendekat tidak disesuaikan dengan berapa banyak mobil dan motor yang lewat. Pendekatutara di mana paling banyak mobil dan motor yang lewat akan tetapi mendapatkan lama lampu hijau yanglebih sedikit dibandingkan pendekat yang lain. Hal ini menunjukkan pengaturan traffic light yang kurangoptimal. Penggunaan metode fuzzy diharapkan dapat menajdikan pengaturan traffic light lebih optimalkarena lama lampu hijau yang dihasilkan lebih bersifat fleksibel sesuai dengan banyak mobil dan motoryang melewati suatu pendekat. Hasil dari penelitian diperoleh untuk kendaraan yang melewati pendekatutara sebanyak 26 mobil dan 177 persiklus diperoleh lama lampu hijau secara manual 43 detik dan denganfuzzy 45 detik. Pendekat barat dengan banyak kendaraan yang melewati sebanyak 25 mobil dan 170 motorpersiklus mendapat lama lampu hijau secara manual 51 detik dan dengan fuzzy 42 detik. Serta untukpendekat timur dengan banyak kendaraan yang melewati sebanyak 24 mobil dan 168 motor per siklusmendapat lama lampu hijau secara manual 53 detik dan dengan fuzzy 42 detik.
