A Novel Seawater-Based Fracturing Fluid for Streamlined Logistics, Long-Term Scale Protection, and Enhanced Oil Recovery
Authors: Ke Linping , Yue Zhiwei , Slocum Andrew , Li Chunli , Larsen Travis
Published: February 2023

Seawater-based fracturing fluid systems are well known for the economic and logistical benefits they provide, including unlocking a usable water source in locations that lack access to fresh water and eliminating the need for extra freshwater supply vessels at offshore wellsites. However, a common challenge with these systems is the formation of scale that results when the high content of sulfate in seawater contacts a barium-rich formation. Additional challenges include minimizing gel residue and mitigating water blockages that can negatively impact oil production after the fracturing treatment. To address these issues, a new seawater-based borate-crosslinked fracturing fluid, with integration of a phosphorus-free polymeric scale inhibitor (SI) and a flowback aid, was developed and evaluated for scale inhibition, oil displacement efficacy and rheological performance.

The seawater-based fracturing fluid rheology and compatibility with a scale inhibitor at varying concentrations were studied in a rotational rheometer. Static bottle test was used to evaluate the long-term barite inhibition. Oil migration and displacement of the fracturing fluid through a column flow apparatus were investigated to demonstrate the synergistic effect of the scale inhibitor and surfactant on enhancing oil mobility through porous media.

Addition of various concentrations of SI does not impair the fluid crosslinking, aging and breaking process, and provides effective scale inhibition over a six-month extended shut-in period. With respect to oil displacement, the frac fluids containing the scale inhibitor and surfactant at certain concentrations outperform the control samples without these additives or that only contained a single additive. It is shown that the seawater-based fracturing fluid has good stability under all shearing schedules and has quick shear recovery after exposure to high shear, indicating the fluid has excellent proppant carrying capacity.

With integration of a polymeric scale inhibitor (SI) and a flowback aid, the seawater-based borate crosslinked fracturing fluid demonstrates reliable rheological performance, superior scale inhibition, and improved oil displacement with reduced water blockage due to the synergistic effect of combining these chemistries.

The integrated fracturing fluid system designed for seawater operations not only provides a reliable fluid performance, long-term scale protection, and better oil recovery, but also significantly reduces logistical costs for offshore applications, especially for those requiring additional supply vessel support to transport frac fluid. All these aspects of the fluid system result in a reduced treatment cost, increased operational efficiency in time and process, reduced fluid waste, and lower CO2 emissions.

Published: February 2023

Computational analysis via the Molecular Dynamics (MD) approach has been used to investigate atomic interactions between Herpesvirus 1 (2GV9) and the Alzheimer's protein (1OWT). The results of MD simulation on the dynamic behavior of this colony have been ascertained with the calculation of numerous physical parameters such as total energy, center of mass (COM) distance and volume of atomic structures. Manipulation of these parameters enabled analysis of the atomic interaction. The calculated COM distances varied from 7.94 Å to 3.72 Å after 1ns which confirmed the traction between the 2GV9 virus and the 1OWT protein. Structurally, the volume of the 1OWT protein increased from 1,056,000 Å3 to 1,786,000 Å3 after atomic interaction with the virus. Moreover, the simulation results showed that temperature is the most critical environmental parameter for the interaction of 1OWT protein and Herpesvirus. Thermal conductivity calculations were performed using t = 1,000,000 time steps to discover the physical stability in the simulated structures. The obtained Green-Kubo results showed that as the temperature changed from 300K to 350K, the thermal conductivity of structures modeled in an aquatic environment increased from 1,233 W/mK to 1,957 W/mK.
Systematic search for thermal decomposition pathways of formic acid on anatase TiO2 (101) surface
Authors: Nabata Hitoshi , Maeda Satoshi
Published: February 2023

This study systematically investigates the reaction pathways for the thermal decomposition of formic acid on the anatase TiO2 (101) surface. The investigation was conducted using a single-component artificial force induced reaction method that combines density functional theory calculations. To uncover the entire mechanism at low surface coverage, we explored reaction path networks for three different conditions of the anatase TiO2 (101) surfaces: clean, protonated, and oxygen-deficient surfaces. Previous temperature programmed desorption (TPD) experiments have shown that H2O desorption starts at a low temperature of around 300 K, while CO and formaldehyde desorption begin to occur at high temperatures of around 500 K. The present reaction path networks are consistent with the overall trend observed in the TPD experiments. By using the reaction paths extracted from these networks, the entire dissociation mechanism was discussed.
A Pd-catalyzed organometallic-free homologation of arylboronic acids enabled by chemoselective transmetalation
Authors: Bastick Kane , Watson Allan
Published: February 2023

A Pd-catalyzed homologation of arylboronic acids is reported. Halomethylboronic acid pinacol esters (BPin) undergo a remarkably facile, yet rare, oxidative addition enabled by an alpha-boryl effect. Simultaneous chemoselective transmetalation allows use of these reagents for formal C1 insertion to deliver benzyl BPin products without the requirement for stoichiometric organometallic reagents. The utility of the process is demonstrated by stepwise C(sp3)C(sp2) cross-coupling of the boronic ester products into diarylmethane pharmacophores and electrophile/nucleophile chemoselective cross-coupling. Control exper-iments that demonstrate the reactivity enhancement provided by the -boryl effect are provided, along with a description of the limitations of the formal homologation process.
A nonequilibrium alchemical method for drug-receptor absolute binding free energy calculations: the role of restraints
Authors: Karrenbrock Maurice , Procacci Piero , Gervasio Francesco Luigi
Published: February 2023

In this paper we further develop a combined Hamiltonian replica exchange / non-equilibrium alchemical method for absolute binding free energies and test its performance on 11 ligands of the BRD4 bromodomain protein. We compare the results obtained with our approach with those obtained with other equilibrium and non-equilibrium alchemical methods showing their relative strengths, weaknesses, and limits. We show how using an enhanced sampling technique, before the alchemical transformations, allows to get accurate estimates of the binding free energies even when starting with sub-optimal initial binding poses (e.g. from docking). We also study the effect of different restraining mechanisms on the final result, and introduce a new "Loose-Tight" restraining algorithm. The method proves to strike a good balance between ease of use, automation, speed, and accuracy for absolute ligand binding free energy calculations and our scripts make it easy to integrate it into pre-existing computational drug discovery pipelines.
Direct Synthesis of Eco-friendly Construction Material from Low-quality Sand via Sol-gel Method
Authors: Qiu Pengcheng , Sakai Yuya , Ogiwara Naoki , Uchida Sayaka , Tamura Yuki
Published: February 2023

A strong, eco-friendly construction material was synthesised directly from low-quality sand via the sol-gel method with ethanol as the solvent. Appropriate KOH content and ethanol concentration further promoted the compressive strength (> 25 MPa). The high strength was attributed to microcline and tetraethoxysilane formation. The carbon emission of the sand-based material in the construction phase was 4281% of those of concrete from four types of buildings based on lifecycle cost analysis. Therefore, a green and tough construction material was synthesised, which can partially substitute concrete, thus addressing the problem of insufficient concrete raw materials and high CO2 emissions.
Thermal Decomposition of Trimethylindium and Indium Trisguanidinate Precursors for InN Growth: An Ab-Initio and Kinetic Modelling Study
Authors: Damas Giane , Rönnby Karl , Pedersen Henrik , Ojamäe Lars
Published: February 2023

Indium nitride (InN) is an interesting material for future electronic and photonic-related applications, as it combines high electron mobility and low-energy band gap for photoabsorption or emission-driven processes. In this context, atomic layer deposition (ALD) techniques have been previously employed for InN growth at low temperatures (typically < 350 C), reportedly yielding crystals with high quality and purity. In general, this technique is assumed to not involve any gas phase reactions as a result from the time-resolved insertion of volatile molecular sources into the gas chamber. Nonetheless, such temperatures could still favour the precursor decomposition in gas phase during the In half-cycle, therefore altering the molecular species that undergoes physisorption and, ultimately, driving the reaction mechanism to pursue other pathways. Thence, we herein evaluate the thermal decomposition of relevant In precursors in gas phase, namely trimethylindium (TMI) and tris(N,N-diisopropyl-2-dimethylamido-guanidinato) (III) (ITG), by means of thermodynamic and kinetic modelling. According to the results, at T= 593 K, TMI should exhibit partial decomposition of ~8% after 400 s to first generate methylindium (MI) and ethane (C2H6), a percentage that increases to ~34% after 1 hour of exposure inside the gas chamber. Therefore, this precursor should be present in an intact form to undergo physisorption during the In half-cycle of the deposition experiment (< 10 s). On the other hand, the ITG decomposition starts already at the temperatures used in the bubbler and it will slowly decompose as it is evaporated during the deposition process. At T= 300 C, the decomposition is a fast process that reaches 90% completeness after 1 s, and where equilibrium, at which almost no ITG remains, is achieved before 10 s. In this case, the decomposition pathway is likely to occur via elimination of carbodiimide ligand. Ultimately, these results should contribute for a better understanding of the reaction mechanism involved in the InN growth from these precursors.

Utilizing solar radiation for driving chemical reactions has been of great interest in the last decade. Although Cu2O nanocrystals as a low-cost, abundant, and tailorable photocatalyst are promising candidates to provide a platform for solar-driven applications, their photophysical properties are affected by the limited charge carrier mobility. This paper focuses on the more efficient utilization of the UV light-excited charge carriers in cuprous oxide by preparing different heterostructures with gold. While keeping the size, shape as well as overall composition of the heterostructures identical, the realization of the gold component is varied: either nanograins are created at the surface of the Cu2O nanooctahedra or nanorods are embedded in their interior. The effect of the morphology and the semiconductor-metal contact on the optical and photocatalytic properties is investigated in-detail by spectroscopy, spectrofluorometry, imaging techniques, X-ray diffractometry, and photoelectron spectroscopy extended with optical simulations and single-particle spectroscopy measurements. In terms of particle stability and photocatalytic activity, gold-decorated Cu2O nanooctahedra show superior properties. The comprehensive comparison of the multicomponent nanoparticles underlines the importance of the nanoscale design (including composition, morphology, and surface chemistry), which utilizes the photoexcited carriers in the semiconductor without injecting hot electrons from the metal.

ADAKAH KONSEP FINIT DALAM BAHASA SUNDA?
Authors: Kurniawan Eri
Published: February 2023

This paper presents an argument that there are no overt morphological manifestations of finiteness in Sundanese. It also provides pieces of evidence that temporal/aspectual auxiliaries do not determine finiteness, as opposed to Kanaâ€™s (1986) and Arkaâ€™s (2000, 2011) claim for Indonesian. Nor are person agreement and modality shown to correlate with a finiteness opposition. Nevertheless, this paper argues that finiteness seems to be at work in Sundanese and that it patterns like other languages to account for the distribution of overt subjects. More specifically, it is proposed that it is the presence of an abstract [finite] feature that licenses an overt subject in a finite clause. As an implication, this establishes a clear-cut dividing line in terms of finiteness along which clausal complements are differentiated. An indicative complement clause is finite owing to their ability of licensing an overt subject, whereas raising and control complements are all non-finite due to the inadmissibility of an overt subject.

THE EXPRESSION OF POSSESSION IN SOME LANGUAGES OF THE EASTERN LESSER SUNDA ISLANDS
Authors: GrangÃ© Philippe
Published: February 2023

The possessor-possessed, or â€œpreposed possessorâ€ syntactic order, has long been considered a typological feature common to many Eastern Lesser Sunda Islands, labelled either â€œCentral-Malayo Polynesian languagesâ€ or â€œEast Nusantara languagesâ€, although these groupings do not exactly coincide. In this paper, the syntax and semantism of possession in some languages of the Eastern Lesser Sunda Islands are described. There is a wide variety of possession marking systems in the Eastern Lesser Sunda Islands, from purely analytic languages such as Lio to highly flexional languages such as Lamaholot. The morphological contrast between alienable and inalienable possession is widespread among the languages of this area. The study focuses on Lamaholot, spoken at the eastern-most end of Flores, and the three neighbouring islands of Adonara, Solor and Lembata. This language has a complex possessive system, involving suffixes, free morphemes, a specific preposition, and possessive pronouns, along with person agreement and morpho-phonological features. Lamaholot can be considered a highly representative example of East NusantaraÂ languages.

A reading habit can be defined as oneâ€™s attitude, behaviour, and mind-set patterns in reading which has been strongly rooted and unchangeable. Indonesiansâ€™ reading habit is still low. According to the 2009 research conducted by the Economic Co-operation Developing Organization [OPKE], the reading interest index of Indonesian people is the lowest among that of 52 East Asian countries. Similarly according to the 2012 data from UNESCO, the Indonesiansâ€™ reading index is 0,001, which means that there is only one out of 1000 Indonesians who is interested in reading. This study aims to describe many different factors affecting the reading comprehension skills and strategies which are in line with those efforts to develop the studentâ€™s reading habit. The subjects of the research are the fifth semester students of 2015/2016 academic year of the Department of Language (Indonesian) of USD and UST Yogyakarta. The data are the questionnaire results on the factors of reading comprehension competency and reading habit strategy developing model. The findings reveal that there are two factors which affect oneâ€™s reading comprehension competency, namely, internal and external factors, and the appropriate reading habit strategy developing models are K-W-L (Know-Want-Learnt) and MURDER (Mood-Understand-Recall-Digest-Expand-Review).

The paper reports a pre-experimental design that aimed to describe the most frequent mistakes in writing effective sentences in academic essays written by university students. The mistakes were classified into five types: sentences without subject, excessively long sentences, run-on sentences, unfinished sentences, and hanging clauses. It also aimed to determine whether two techniques called Consciousness Raising and Noticing techniques could help the subjects reduce the proportion of their ineffective sentences. The ten subjects were instructed to write academic essays before being taught with the two techniques, and later were instructed again to write essays after being taught with the two techniques. The whole treatment spanned a semester, consisting of twelve sessions in the classroom. The result indicated that run-on sentences, hanging clauses, and excessively long sentences were the most frequent mistakes in their essays. Meanwhile, the Consciousness-Raising and Noticing techniques only had a significant impact on the category of excessively long sentences. The subjects made significantly fewer mistakes in this category after the application of the two techniques. Some implications for further research and practical applications are then presented.

This article discusses phonological, morphological, syntactical and sociolinguistic aspects of the Sambori language spoken by the people of Sambori and its surroundings on Mount Lambitu, Bima, West Nusa Tenggara. The language and its cultures are in the endangered situation due to internal factors (for example due to mixed marriage and migration) and external factors (for example, due to economic, demographic and political pressures). The study documents the language by identifying its dialectological relation with the locally dominant Bima language and with other languages in the region (e.g. Samawa language and Sasak language). Identification was conducted by using elicitation, documentation, interview, and recording. Elicitation was performed in face-to-face interviews with respondents guided by a list of basic words and morphosyntactic forms. Documents were also collected from various forms of oral documents (e.g. folklores, stories, historical accounts and legends) in the language. Interviews were given to adult male and female speakers who are knowledgable of the language and its culture. The data were recorded by using tape recorders and digital cameras. Linguistic analysis was lexicostatistictal and the results show that the the Sambori language is a dialect of the Bima language with differences at the basic word level, but these differences follow predictable patterns of vowel and consonantal changes.

This study aims to describe the comparison of the following items: (1) the form and (2) the location of speech disfluencies in script-based speech and extemporaneous speech by BIPA students. This research is a qualitative descriptive study. The research data is in the form of speech impediments in the speeches of BIPA students who were captured using the listening method and then analyzed using the disappearing technique. The results of data analysis showed that the fluency of extemporaneous speech was significantly higher than that of script-based speech. The forms of speech impediment include (1) pause filler, (2) repetition, (3) lengthening, and (4) revision. In this case, there is no difference in the characteristics of speech impediments in the two speeches. The speech impediment occurs: (1) before the sentence, (2) the clause limit, (3) the constituent limit, and (4) within the constituent. In this case, extemporaneous speech is dominated by the location of speech impediments (1) and (2), while script-based speech is dominated by (3) and (4) which indicates that the obstacle in script-based speech lies in word recall, while the obstacle in extemporary speech lies in message formulation.Penelitian ini bertujuan untuk mendeskripsikan perbandingan (1) bentuk dan (2) letak ketidaklancaran tuturan (speech disfluencies) pada pidato berbasis naskah dan pidato ekstemporan pemelajar BIPA. Penelitian ini merupakan penelitian deskriptif kualitatif. Data penelitian berupa ketidaklancaran tuturan dalam pidato mahasiswa BIPA yang dijaring dengan metode simak kemudian dianalisis dengan teknik lesap. Hasil analisis data menunjukkan ketidaklancaran tuturan pidato ekstemporan secara signifikan lebih tinggi daripada pidato berbasis naskah. Bentuk ketidaklancaran tuturan meliputi (1) pengisi jeda, (2) pengulangan, (3) pemanjangan, dan (4) revisi. Dalam hal ini, tidak ada perbedaan karakteristik bentuk ketidaklancaran tuturan dalam kedua pidato. Ketidaklancaran tuturan terjadi (1) sebelum kalimat, (2) batas klausa, (3) batas konstituen, dan (4) di dalam konstituen. Dalam hal ini, pidato ekstemporan didominasi letak ketidaklancaraan tuturan (1) dan (2), sedangkan pidato berbasis naskah didominasi (3) dan (4) yang mengindikasikan bahwa hambatan pada pidato berbasis naskah terletak pada recall kata, sementara hambatan  pada pidato ekstemporan terletak pada formulasi pesan.

Iterative verbs are verbs that express an activity which occurs many times or repeatedly. Iterative verbs are characterized by language forms that arise as a result of morphological processes. This study describes the types of iterative verbs in Sundanese language in their morphological behavior. Iterative verb data were obtained from written sources using the listening method for providing data and followed by note-taking techniques. The data were analyzed using the distributional method with the two-by-two opposition technique. The results showed that morphologically iterative Sundanese verbs are characterized by affixation and reduplication. There are seven types of iterative verb marker affixations in Sundanese, namely D-an, di-D-an, di-D-ar-an, N-D-an, N-D-ar-an, ka-D-an, and (pa)ting +D. Meanwhile, reduplication of iterative verb markers in Sundanese is dwilingga dwimurni, dwilingga dwireka, dwilingga with R-keun suffix, dwilingga with N-R-keun confix, dwilingga with ka-R prefix, dwipurwa reduplication, dwipurwa with prefix and suffix ti–ar-R, dwilingga and dwipurwa with the suffix R-an, dwilingga and dwipurwa with the confix di-R-keun. The accompanying markers for iterative verbs are hantem, teu weleh, tansah, haben, mindeng, remen, often, osok, kungsi, and sometimes.Verba iteratif merupakan verba yang menyatakan suatu aktivitas yang terjadi berkali-kali atau berulang-ulang. Verba iteratif ditandai oleh bentuk bahasa yang muncul akibat proses morfologis. Dalam penelitian ini digambarkan jenis verba iteratif bahasa Sunda dalam perilaku morfologisnya. Data verba iteratif diperoleh dari sumber tertulis dengan metode simak untuk penyediaan data dan dilanjutkan dengan teknik catat. Data dianalisis dengan metode distribusional dengan teknik oposisi dua-dua.

Published: February 2023

У статті обґрунтовано комунікативну спрямованість навчання діалогічного та монологічного мовлення у процесі підготовки студентів- філологів. Відповідно до впровадженого компетентнісного підходу, який реалізується в діалогічній та монологічній формах, визначено, що сьогодні важливу цінність має формування монологічного і діалогічного мовлення у студентів-філологів. Це пов’язано з тим, що діалогізація відображає природу дидактичної взаємодії, сприяє створенню сприятливих умов для здійснення діалогічного спілкування у системі відносин «науково- педагогічний працівник ‒ студент» на практичних заняттях з англійської мови, а монолог в процесі мовленнєвого спілкування знаходиться в постійній взаємодії з діалогом. У процесі аналізу даної проблематики було розглянуто особливості навчання монологічного та діалогічного мовлення студентів-філологів на практичних заняттях з англійської мови. Крім того, описано різні методи, вправи, прийоми та технології з метою розвитку комунікативно- мовленнєвих умінь майбутніх філологів в процесі виконання ними різних форм монологічного та діалогічного мовлення, що сприяє формуванню комунікативних, мовленнєвих, професійних умінь і навичок спілкування, а також сприяє вираженню вербальних засобів спілкування, що активізує навчальний процес і забезпечує оволодіння студентами-філологами матеріалу лексичного та граматичного характеру. Сформовано висновки, що добре розвинене зв’язне мовлення студента- філолога має вагоме значення у формуванні та розвитку особистості, допомагає мислити чітко і ясно в процесі висловлювання та легко налагоджувати контакти, підтримувати розмову і спілкуватися з людьми.

Стаття присвячена проблемі впровадження інновацій у вищих навчальних закладах. Аналіз літературних джерел, предметом якого є впровадження інноваційних технологій в освітнє середовище сучасного навчального закладу з урахуванням позитивного європейського досвіду в сучасній Україні, свідчить про значний інтерес науковців до цих питань. На думку дослідників, вищі навчальні заклади можуть успішно працювати за наявності відповідної підтримки з боку держави та розробки концепції розвитку, як економіки держави загалом, так і її провідної складової частини – вищої освіти. Визначено загальні тенденції. Це: реформування системи професійної підготовки фахівців, інноваційна спрямованість професійної підготовки вчителів. Проаналізовано стан проблеми, вивчено зарубіжний досвід та намічено шляхи його використання. Зазначається, що процеси реформування освіти спрямовані на здобуття майбутніми фахівцями знань, умінь і навичок, перетворення їх у компетентності, що забезпечить успішність їхнього професійного та особистісного розвитку, готовність мобільно реагувати на виклики часу, реалізацію суспільно важливі завдання – навчання впродовж життя. Використання технологій змішаного навчання – це нова організація навчального процесу, яка викликає багато питань до викладачів та адміністрації вищих навчальних закладів: вибір засобів роботи, організація дистанційного навчання; оцінювання учнів та контроль за їхньою навчально-пізнавальною діяльністю, розробка або вибір моделі змішаного навчання, налагодження ефективної взаємодії всіх учасників навчального процесу, забезпечення якості освіти. Перспективним напрямком змішаного навчання є інтеграція онлайн- навчання з традиційним.
ВИКОРИСТАННЯ СУЧАСНИХ ІНФОРМАЦІЙНИХ ТЕХНОЛОГІЙ У ВИКЛАДАННІ МЕДИКО-ХІМІЧНИХ ДИСЦИПЛІН ПІД ЧАС ДИСТАНЦІЙНОГО НАВЧАННЯ

У статті описується досвід використання сучасних методик інформаційних технологій під час вивчення предметів «Медична хімія» і «Біологічна та біоорганічна хімія» в медичному університеті. У роботі обґрунтовано доцільність упровадження саме тих технологій, які охоплювали би всі етапи навчання за циклової системи. Мотивація та правильна постановка мети й цілей для студентів є тією рушійною силою, яка буде спонукати їх до успішного завершення вивчення предмета. Тому у статті розглядається застосування спеціальних освітніх дорожніх карт, які студенти формували разом із викладачем. Техніка «OKR – Objective & Key Results» допомогла правильно сформувати завдання, цілі для кожного студента, а також створити власний план реалізації поставлених завдань. Доведено ефективність використання на заняттях із хімії медичного спрямування різноманітних завдань із застосуванням цифрових платформ (наприклад, Canva), онлайн-дошок, гейміфікованих онлайн-програм для вирішення тестових завдань (наприклад, Кahoot), що викликають зацікавленість та спонукають творчо мислити й заглиблюватися у вивчення дисципліни. Також проаналізовано результати співпраці викладача та студентів. Для цього проведено підсумкові вправи на етапі завершення вивчення предмета, а також удосконалено вміння студентів робити самоаналіз. Було використано методику, що отримала назву «Key Performance Indicators», яка дає змогу визначити те, наскільки ефективно працював студент, щоб досягнути поставлених цілей. Крім того, у статті проаналізовано роботу вчених у цьому напрямі, розглянуто їхній досвід застосування інформаційних технологій в освітньому процесі для покращення сприймання матеріалу здобувачами освіти. У статті порівнюються та узагальнюються результати роботи студентів і їх враження від навчання за техніками сучасних ІТ. Згідно з даними, що отримані під час спілкування, анкетування, та за рівнем знань зроблено висновок, що активізація діяльності студентів різними сучасними засобами цифровізації дає позитивний результат. Знання, які отримані здобувачами освіти, є більш ґрунтовними та глибокими.
