У кроликов моделировали офтальмогипертензию (ОГ), стрептозотоциновый диабет (СТД), а также ОГ+СТД. В тканях угла передней камеры глаза изучали уровень окисленной и восстановленной формы глутатиона (GSSG и GSH), дисульфидных и сульфигидрильных (SS- и SH-) групп белков. Установлено, что в группе моделирования ОГ на фоне СТД наблюдались наиболее выраженные изменения глутатионового статуса в изучаемых тканях среди экспериментальных групп. Отмечено снижение восстановительного потенциала глутатиона при сочетанной патологии в тканях угла почти в 2 раза. Изменение здесь количественного состава функциональных групп белков подтверждает повреждение структуры молекул белков в тканях дренажной зоны глаза вследствие усиленного оксидативного стресса при повышенном внутриглазном давлении на фоне диабета. Высокое внутриглазное давление, таким образом, является фактором, усугубляющим метаболические нарушения в тканях глаза при развитии диабета.

Актуальність. Вивчення динаміки суб’єктивних клінічних симптомів при лікуванні пацієнтів із травматичним кератитом зі застосуванням додаткової оксигенації має практичне значення, оскільки під час запалення рогівки відбувається гіпоксія тканин. Мета роботи: вивчити динаміку інтегральних показників клінічних симптомів при лікуванні травматичного кератиту зі застосуванням гіпербаричного кисню. Матеріали та методи. До дослідження було включено 69 пацієнтів (69 очей) із травматичним кератитом віком від 18 до 75 років, серед яких 70 % становили чоловіки. Всім пацієнтам до стандартної схеми лікування травматичного кератиту було включено гіпербаричну оксигенацію з емоксипіном один раз на добу протягом 6–10 днів тривалістю 40 хвилин за режимом 1,2 АТА в барокамері «Ока». Вивчалася динаміка клінічних суб’єктивних показників у пацієнтів основної та контрольної груп, виражена в балах за умовною шкалою, що розроблена нами. Результати та обговорення. Аналіз динаміки інтегральної бальної оцінки суб’єктивних проявів під час лікування хворих на травматичний кератит свідчить про суттєве поліпшення стану ока в пацієнтів основної групи (із застосуванням гіпербаричної оксигенації). Інтегральний показник суб’єктивних клінічних симптомів пацієнтів основної групи на кінець лікування зменшився на 90,94 % (р < 0,001), що відповідає різниці між групами в 51,21 %. Порівняно з контрольною групою інтегральний показник включав зменшення середньої бальної вираженості відповідно: світлобоязні — 77,78 %, сльозотечі — 41,94 %, відчуття стороннього предмета — 41,67 %, больового синдрому та печіння — по 36,84 % (р < 0,001). Термін зникнення суб’єктивних клінічних симптомів основної групи коливався в межах 1,91 ± 0,01 — 2,15 ± 0,01, а контрольної групи — 3,79 ± 0,01 — 4,07 ± 0,01, р < 0,01. Висновки. Застосування додаткової оксигенації до традиційного лікування травматичного кератиту зменшує інтегральний суб’єктивний показник у балах пацієнтів основної групи на кінець лікування на 90,94 %, що відповідає різниці між групами майже в 49 % (р < 0,01). Використання ГБО-терапії сприяло одужанню хворих основної групи через 6,26 ± 0,03 дня, а групи контролю — через 9,31 ± 0,02 дня (р < 0,01), тобто на 3,05 дня раніше.

Simulasi Numerik Prediksi Erosi Aliran Fasa Cair-Gas Berpasir Pada Belokan Pipa Sumur Minyak Mentah Menggunakan Model Finnie, McLaury dan Oka
Authors: Atmaja Haryadi Jaya , Kamal Samsul , Sugiyono S
Published: January 2022

Keberadaan pasir dalam fluida produksi di industri perminyakan merupakan hal yang tak dapat dihindari. Pada kecepatan fluida tertentu, pasir berpotensi menimbulkan erosi pada dinding perpipaan yang apabila proses tersebut terjadi secara terus menerus maka dapat menyebabkan penipisan dinding pipa, mengurangi tekanan kerja maksimum fluida yang diijinkan, kegagalan pipa dan akhirnya fluida hidrokarbon keluar dari sistem tertutup pipa. Kondisi ini berpotensi menimbulkan kerugian dalam hal keselamatan kerja, kehilangan finansial dan isu lingkungan. Kompleksitas mekanisme erosi akibat fluida berpasir didalam perpipaan memerlukan bantuan perangkat lunak untuk menghitung besaran dan profil erosi didalam pipa. Makalah ini memprediksi laju erosi aliran multifasa cair-gas-padat pada belokan pipa yang didominasi fasa cair dengan CFD menggunakan ANSYS Fluent 18.2 dengan validasi berdasarkan eksperimen yang dilakukan peneliti lain yang sudah dipublikasi. Dari hasil simulasi, laju erosi dengan model Oka lebih mendekati hasil eksperimen dibandingkan model Finnie dan McLaury. Hal ini dimungkinkan karena kondisi eksperimen lebih sesuai dengan model erosi yang dibangun oleh Oka. Hasil simulasi lanjutan menunjukkan bahwa laju erosi pada pipa meningkat dengan kenaikan laju alir dari minyak mentah dan gas, ukuran partikel dan laju alir partikel. Laju erosi menurun dengan meningkatnya diameter pipa.

Published: January 2022

Salah satu peralatan bawah sumur (sub-surface) yang dipasang saat tahappenyelesaian sumur adalah sand control devices untuk mencegah agar pasir di dalam reservoir tidak ikut terproduksi ke permukaan sumur. Sand control devices sebagian besar menggunakan pipa berlubang(perforated pipe) sebagai base pipe yang terpasang pada lubang sumur (wellbore). Salahsatu parameter penting yang mempengaruhi laju alir fluida dari reservoir menuju lubang sumur adalah penurunan tekanan total (total pressure drop). Pipa berlubang memiliki desain yang beragam tergantung dengan kebutuhan di lapangan. Dalam mendesain suatu pipa berlubang maka yang perlu diperhatikan adalah jenis material dan dimensi pipa berlubang, jumlah lubang (perforation density), sudut fasa dan pola distribusi lubang perforasi. Untuk dapat mengetahui perilaku pola aliran (axial and radial inflow) yang melalui pipa berlubang sebagai base pipe dari sand control devices akibat pengaruh sudut fasa perforasi (60o, 90°, 180°) dan pola distribusi lubang perforasi bentuk staggered dan non-staggered maka dilakukan simulasi numerik menggunakan software ANSYS 18.2. Model turbulen yang digunakan adalah k-ε standard dan simulasi dilakukan dengan 5 kondisi flow rate ratio yaitu 0%, 10%, 15%, 20% dan 30%. Hasil simulasi pengaruh sudut fasa lubang perforasi menunjukkan bahwa sudut fasa 60° memiliki penurunan tekanan total paling rendah dibandingkan dengan dua sudut fasa lainnya. Sedangkan pada pengaruh pola distribusi lubang didapatkan bahwa pola distribusi model non-staggered memiliki penurunan tekanan total paling rendah dibandingkan dengan dua model pola distribusi staggered (screw dan non screw).

Authors: Wildan Muhammad Waziz , Marpaung F
Published: January 2022

Porous ceramics are a form of ceramic material with widespread applications, such as filters, isolators, and acoustics. This research aimed to investigate the compressive strength and thermal conductivity of porous mullite ceramics (3Al2O3.2SiO2 or Si2Al6O13) produced using dry yeast powder as a PFA (pore-forming agent). Kaolin powder (Al2O3.2SiO4.2H2O or Al2Si2O5(OH)4) was used as a raw material for producing mullite ceramics. Kaolin powder and dry yeast powder were mixed at a variety of dry yeast powder weight fractions: 0%, 5%, 10%, 15%, 20%, and 25%. The composition was mixed using Turbula Mixer for 1 hour. The cylindrical green body (diameters of 12 mm, 15 mm, and 30 mm) of every constituent was formed by the uniaxial pressing method at 10 MPa. Monolithic kaolin was sintered at variable temperatures (1,100 oC, 1,200 oC, 1,300 oC, 1,400 oC, 1,450 oC) for 2 hours then subjected to several tests for its density. From the bulk density tests, it was found that the optimum temperature for 2-hour sintering was 1,450 oC. This temperature was then used for the sintering process of the kaolin specimens which contained dry yeast powder. Testing was performed on the microstructure, bulk density, burning waste in mass and volume, compressive strength, and thermal conductivity. According to the literature, kaolin will transform into mullite (3Al2O3.2SiO2 or Si2Al6O13) and cristobalite (SiO2) at 1,450 oC. It was found that with the increase in the content of dry yeast powder as PFA in the mixture with kaolin, the bulk density decreased (from 2.44 gr/cm3 to 1.521 gr/cm3), the porosity increased (from 23.77% to 52.48%), the compressive strength decreased (from 38.04 MPa to 4.51 MPa), and the thermal conductivity decreased (from 3.76 W/moC to1.34 W/moC), each from yeast powder content 0% to 25%.

Authors: Ismadi Ignatius Henry , Nugroho Gesang
Published: January 2022

Composite materials uses have been increasingly ubiquitous due to their advantages, for example, in being strong, lightweight, and rust-resistant. Various composite manufacturing processes are designed to obtain composite products of better quality, including minimizing the number of pores or voids trapped within and increasing the fiber volume fraction until an optimal value is achieved. The method employed in this research was the bladder compression molding method, and the materials used were woven carbon fabric and epoxy matrix. According to previous research which used this method, the higher the pressure in the bladder, the better the product quality generated. The aim of this research was to investigate the effect of changes in the pressure level in the bladder (1, 2, 3, 4, 5, 6, 7, and 8 bar) on the mechanical properties of the composite produced. The test specimen was gained by cutting the composite product with a CNC router machine. The tensile test results indicate that the ultimate testing tensile strength was 604 MPa and that the optimal pressure in the bladder was 7 KPa. The conclusion of this research is that the composite product quality would increase with the progressive increase in the bladder pressure to the point of optimal pressure.
The effect of AA5083H116 2-layer MIG welding speed on physical and mechanical properties
Authors: Mudjijana M , Malau Viktor , Salim Urip Agus
Published: January 2022

Metal welding can be performed on 1 layer or more depending on the thickness of the plate welded. In the case of 3-mm-thick plates, high-efficiency welding can be carried out on 1 layer if appropriate welding speed, voltage, and amperage are applied. If two layers are to be used, sound weld of 3-mm-thick plates can be achieved if higher welding speed and lower voltage and amperage are applied. This research was intended to conduct 2-layer MIG weld works at welding speeds of ≥10, 13, and 16 mm/s in accordance with previous research studies and to analyze the physical and mechanical properties generated. This research employed the AA5083H116 material, ER5356 electrode, and argon gas. During the welding processes, the thermal cycles were recorded, and after the processes, the welding results were observed for the macro- and microstructures and for the optimal welding speed under an SEM. In addition, tensile tests, Vickers microhardness tests, and corrosion tests were also undertaken. The results show that the 2-layer MIG welding at the welding speed of 10 mm/s produced the best physical and mechanical properties.

Performance Performance Analysis of Tubular PEM Fuel Cell Models and Thermal Analysis of Base Model using Ethylene Glycol-Water Mixture as a Coolant
Authors: Ambekar Tejas
Published: January 2022

Abstract: This work aims towards the simulation of Various proton exchange membrane fuel cell (PEMFC) models to investigate the effects of operating parameters such as temperature, pressure, anode flow levels and cathode reactants, component types, cooling temperatures in the performance of a modified fuel cell. The basic model and the tubular model are developed in modelling software based on the size of the parameter later simulated using the addon module in the Ansys software. The Addon module is specifically designed to mimic a different type of fuel cell. The simulated model of cell power output showed positive compliance with experimental results taken from the literature and revealed that the operating pressure, temperature, and flow rate of reactants positively affect the function of the Fuel cell. The results also showed that the cooling temperature of the coolant indicates higher concentrations of current congestion compared to the base model without cooling. Corrective results obtained from the effect of temperature on cell function showed that the fuel cell temperature favor both cell function and efficiency. It can therefore be assumed that the efficiency of the cell is strongly influenced by operating temperature, pressure, cooling temperature, fuel flow rate and oxidant. Keywords: PEM fuel cell, Current density, tubular fuel cell, addon-module.

Authors: Pancaningtyas Sulistyani
Published: January 2022

Clonal propagation is an alternative method of maintaining the genetic purity of superior cocoa plants (Theobroma cacao L.). The somatic embryogenesis technique is likely the most effective and efficient method for plant propagation. This study aimed at investigating the callogenesis and embryogenic potential of new superior cocoa clones on culture media added with various concentrations of antioxidants and variation in the concentration of auxin hormone combined with ascorbic acid. The superior clones used in this study were MCC 01, MCC 02, Sulawesi 3, ICCRI 07, and ICCRI 09. The parameters observed in this study were percentage of embryogenic callus formation, number of secondary somatic embryos, and percentage of embryo somatic cells that develop into planlets. The addition of 2,4,5-T combined with ascorbic acid affected the initiation of cocoa secondary somatic embryogenesis. Treatment combination of ascorbic acid 100 mg.L-1 and 2,4,5-T 1 mg.L-1 had a significant effect on the initiation of secondary somatic embryogenesis of cocoa in the embryogenic callus phase (4.73%), globular embryos (2.53%), torpedo embryos (4.67%) and sprouts (0.47%). Three clones i.e ICCRI 07, Sulawesi 3 and ICCRI 09 clones showed a higher percentage (3.0%, 2.10%, and 1.80%, respectively) of embryogenic callus growth than the other clones. Meanwhile, on MCC 01 clone, all treatments did not affect the regeneration of embryogenic callus. The combination treatment of organic acid and adenine showed a low embryogenic callus response in MCC 01 and MCC 02 clones. However, MCC 02 clone also did not show a response in form of globular, torpedo, and germination phase somatic embryo regenerations. This indicates that different plant cultivars show different responses to the addition of organic acids.

Earthworm is one of the important macro-fauna in cocoa plantation ecosystem that affects the structure and activity of soil microbes. Earthworms maintain nutrient cycle and affect the growth of plants. Cocoa is a plant that requires shade trees. The presence of shade trees is to increase soil fertility and enrich diversity offlora and fauna. The purpose of this study was to investigate the diversity and abundance of earthworms in cocoa farms with different shade trees, namely paranet, areca palm + leucaena, coconut + leucaena, oil palm + leucaena, and leucaena. The study was carried out in Kaliwining Experimental Station of Indonesian Coffee and Cocoa Research Institute, Jember. Earthworms were picked manually to a depth of 30 cm by purposive sampling method from July to October 2020. The cocoa plants used were mature plants with a spacing of 3 m x 3 m. Based on Shannon and Wiener formula, the results showed that earthworm diversity was low in all treatments. Earthworms until family level were identified. Earthworm families of Glososscolicidae and Megascolocidae were found in this study. The highest abundance of earthworms was found in areca palm + leucaena. Soil organic C and N content and sand fraction were positively correlated with earthworm abundance, while silt fraction and soil density were negatively correlated with earthworm abundance. As micro-climate factor, light intensity was positively correlated with earthworm abundance, while air temperature was negatively correlated with earthworm abundance.

Quantum error correction procedures have the potential to enable faithful operation of large-scale quantum computers. They protect information from environmental decoherence by storing it in logical qubits, built from ensembles of entangled physical qubits according to suitably tailored quantum error correcting encodings. To date, no generally accepted framework to characterise the behaviour of logical qubits as quantum memories has been developed. In this work, we show that generalisations of well-established figures of merit of physical qubits, such as relaxation times, to logical qubits fail and do not capture dynamics of logical qubits. We experimentally illustrate that, in particular, spatial noise correlations can give rise to rich and counter-intuitive dynamical behavior of logical qubits. We show that a suitable set of observables, formed by code space population and logical operators within the code space, allows one to track and characterize the dynamical behaviour of logical qubits. Awareness of these effects and the efficient characterisation tools used in this work will help to guide and benchmark experimental implementations of logical qubits.

As social beings, humans need other individual to survive. In social life, humans interact and communicate with each other using languages which use to ask for help or exchange information. Often in verbal or non-verbal communication, someone provides information that has two or more different meaning thus confusing the interlocutors, this condition of information call ambiguous. This study entitle “A Structural Ambiguity Analysis In Sentences Found in The Skeleton Key Novel” is aimed to identify one of the types of surface ambiguity in the structural ambiguity in sentences found in The Skeleton Key novel, and to analyze pattern of structural ambiguity in sentences that were found in The Skeleton Key novel by tree diagrams. The data of this study were analyzed by using the qualitative method. From 12 data that were found in the data source, one of the data were analyzed as the sample of this study. From six types of surface ambiguity propose by Kriedler (1998) only one of the types was analyzed for this research. It was a coordinate head with one modifier. In this research, the researcher found that the structure of sentence structure will affect the meaning of the sentence itself. Thus the analysis of sentence structure using tree diagram will produce different meaning according to intented construction in tree diagram.

This study has two purposes, those are (1) to find out the types of code-switching used in conversation between Daniel Mananta and Raline Shah in “Daniel Tetangga Kamu” video YouTube channel and 2) to identify the functions of code-switching used in conversation between Daniel Mananta and Raline Shah’s utterances. A qualitative method is used for this study for analyzing the data collected from five videos. The method is applied to give a clear description of the data according to the theory proposed by Poplack (1980) as cited in Romaine (1989: 122) about the three types of code switching. The result of this analysis showed that there was three types of code switching found in this conversation are; Tag switching, intra-sentential switching and inter-sentential switching. Type of code-switching which is intra-sentential switching is the most often used in conversation between Daniel Mananta and Raline Shah utterances because they was more comfortable when using words, clauses, and phrases in one sentence to convey motivational messages. And the theory proposed by Appel and Muysken (1987) about the six functions of code switching. In this analysis showed that there was six function of code switching are; referential, directive, expressive, phatic, metalinguistic and poetic. Metalinguistic is the dominant function of code-switching in conversation between Daniel Mananta and Raline Shah’s utterances. It occurs because Daniel Mananta and Raline shah wanted to impress the other participants with a show of linguistic skill.

Fokas Method for the Heat Equation on Metric Graphs
Authors: Sobirov Z. A. , Eshimbetov M. R.
Published: January 2022

The paper presents a method for constructing solutions to initial-boundary value problems for the heat equation on simple metric graphs such as a star-shaped graph, a tree, and a triangle with three converging edges. The solutions to the problems are constructed by the so-called Fokas method, which is a generalization of the Fourier transform method. In this case, the problem is reduced to a system of algebraic equations for the Fourier transform of the unknown values of the solution at the vertices of the graph.
