An Architectural Scenography of the Humanist Ideas of the Spanish Renaissance
Authors: Сим Надежда Михайловна
Published: August 2022

В статье рассматривается историческая роль кардинала Педро Гонсалеса де Мендосы и его наследников как меценатов и благотворителей, которые, подобно Медичи, внесли богатый вклад в культурное наследие испанского Возрождения. На примерах культовой и дворцовой архитектуры Кастилии и Андалусии, где Мендосы выступали основными заказчиками и авторами проектов, проанализирован поиск художественных тенденций от строгого следования итальянским образцам до синтеза восточных и западных культур, определивших в итоге характерные национальные черты иберийской архитектуры.

The article examines the activities of Cardinal Pedro González de Mendoza and his heirs as patrons and benefactors of Spain, who, like the Medici family, made their rich contribution to the cultural heritage of the Spanish Renaissance. Considering the examples of cult and palace architecture of Castile and Andalusia, where the Mendoza family acted as major customers and designers, the author explores the processes of searching for artistic trends, from strict adherence to Italian models to the harmonious synthesis of Eastern and Western cultures. This determined the characteristic national features of Iberian architecture.
Improvement of the technology of preparation of concrete mixtures through the use of superplasticizer C-3
Authors: Вардак Мохаммад Алем
Published: August 2022

В статье представлены современные методы и технологии приготовления бетонных смесей, обладающих наилучшими технико-экономическими показателями для возведения монолитных зданий. Рассмотрен метод использования добавок (суперпластификатора С-3), улучшающих технологические параметры, механические свойства бетона и качество работ. Автор предлагает за счет применения добавки суперпластификатора С-3 в бетонную смесь в количестве 0,4 % от массы цемента увеличить прочность на сжатие на 10-15 МПа, а также улучшить технологические параметры. Более эффективной оказалась пропорциональная загрузка барабана сразу всеми составляющими смеси, при подаче сухих компонентов «слоеным пирогом» на ленту конвейера и одновременной заливке воды (15 % воды, в конце загрузки).

The article discusses modern methods and technology for the preparation of concrete mixtures with the best technical and economic indicators for the construction of monolithic buildings. We have considered methods, technologies and additives (superplasticizer C-3), due to providing technological parameters, mechanical properties of concrete and good quality of work. As a result, the author proposes that, due to the use of the addition of superplasticizer C-3 to concrete mixtures in the amount of 0.4 % by weight of cement, it increases the compressive strength by 10 Map as well as improving technological parameters, and more effective was the proportional loading of the drum with all the components of the mixture at once when the dry components were fed in a «layer pie» on the conveyor belt and at the same time pouring water (15 % water, at the end of the load).

Published: August 2022

Photocatalytic water-splitting provides a way to store solar energy as hydrogen gas, and hence, is an attractive alternative to energy-intensive electrolysis of water. Microporous polymer networks are an interesting class of heterogeneous photocatalysts due to the chemical modularity of their optically active backbone and their guest-accessible pore-structure. Photocatalytic action depends on efficient separation of photoexcited electron-hole pairs, and recently, it was discovered that this separation can be improved by incorporation of donor-acceptor motifs into the polymer backbones. While there are many examples of electron donors, there is little variety in electron acceptor motifs. Here, we present a series of microporous donor-acceptor networks that contain electron-deficient boron moieties (triarylborane) as the electron acceptors and sulfur moieties (thiophene) as the donors. Under sacrificial conditions, these sulfur- and boron-containing polymers (SBPs) show rates of hydrogen evolution up to 113.9 mmol h-1 g-1. Conventionally used platinum co-catalyst does not contribute meaningfully to the photocatalytic action. Instead, palladium that is incorporated during the stage of polymer synthesis acts as the co-catalyst.

The recent interest in microscopic autonomous systems, including microrobots, colloidal state machines and smart dust has created a need for microscale energy storage and harvesting. However, macroscopic materials for energy storage have noted incompatibilities with micro-fabrication techniques, creating significant challenges to realizing microscale energy systems. Herein, we photolithographically pattern a microscale Zn/Pt/SU-8 system to generate the highest energy density microbattery at the picoliter (10^-12 L) scale. The device scavenges ambient or solution dissolved oxygen for a Zn oxidation reaction, achieving an energy density ranging from 760 to 1070 Wh L-1 at scales below 100 μm lateral and 2 μm thickness in size. More than 10,000 devices per wafer can be released into solution as functional colloids with energy stored onboard. Within a volume of only 2 pL each, these microbatteries can deliver open circuit voltages of 1.16 V with total energies ranging from 5.5 ± 0.3 to 7.7 ± 1.0 μJ and a maximum power near 2.7 nW. We demonstrate that such systems can reliably power a micron-sized memristor circuit, providing access to non-volatile memory. We also cycle power to drive the reversible bending of microscale bimorph actuators at 0.05 Hz for mechanical functions of colloidal robots. Additional capabilities such as powering two distinct nanosensor types and a clock circuit are also demonstrated. The high energy density, low volume and simple configuration promise the mass fabrication and adoption of such picoliter Zn-air batteries for micron-scale, colloidal robotics with autonomous functions.
Sensitivity analysis methodology for battery degradation models
Authors: Appiah Williams Agyei , Busk Jonas , Vegge Tejs , Bhowmik Arghya
Published: August 2022

Accurate degradation models are crucial to battery design and management. However, the time and resources required to improve the accuracy of the model input factors that the output is sensitive to, which is essential for elucidating the inherent dominant mechanism in the model, remain a challenge. Here we present a sensitivity analysis of a pseudo-two-dimensional battery model coupled with a capacity fade model based on solid electrolyte interphase formation and the corresponding irreversible charge loss for Li-ion batteries. The proposed method is based on training an inexpensive differentiable surrogate Gaussian process regression model on observed input-output pairs and analysing the surrogate model to learn about the global and local sensitivities of the original system. With this method, the relevant global sensitive parameters can be identified, and an in-depth analysis of electrochemical phenomena such as the correlation between the thickness of the solid electrolyte interphase and the irreversible charge loss can be explored. This proposed method will provide key insight into how the sensitivity analysis of the physics-based degradation model must be conducted for effective integration into battery management systems.

Newton-X is an open-source computational platform to perform nonadiabatic molecular dynamics based on surface hopping and spectrum simulations using the nuclear ensemble approach. Both are among the most common methodologies in computational chemistry for photophysical and photochemical investigations. This paper describes the main features of these methods and how they are implemented in Newton-X. It emphasizes the newest developments, including zero-point-energy leakage correction, dynamics on complex-valued potential energy surfaces, dynamics induced by incoherent light, dynamics based on machine-learning potentials, exciton dynamics of multiple chromophores, and supervised and unsupervised machine learning techniques. Newton-X is interfaced with several third-party quantum-chemistry programs, spanning a broad spectrum of electronic structure methods.

Published: August 2022

Two-photon absorption has wide applications in bioimaging, photodynamic therapy, and three-dimensional printing. De-signing molecules with a large two-photon absorption cross section (TPACS) is thus highly desirable for advancing these technologies. Here we used machine learning to analyze a TPACS dataset of ca. one thousand molecules collected from literature reports. We found that the length of the conjugated structure is the most important feature to determine the TPACS in a power law of ~1.8 order. The effect of donor and acceptor substitutions and structural coplanarity on the TPACS can be adequately addressed by another three features obtained by empirical rules. Combining these four molecular features with the experimental wavelength and solvent used in the measurement, we derived an interpretable model to predict molecular TPACS with an accuracy comparable to that of experimental measurements and common theoretical calculations. Our approach not only provides insight into the factors that are critical to TPACS but, as we demonstrate, also allows high-throughput screening of new TPA molecules.

Needle-and-syringe-based delivery has been the commercial standard for vaccine administration to date. With worsening medical personnel availability, increasing biohazard waste production, and the possibility of cross-contamination, we explore the possibility of biolistic delivery as an alternate skin-based delivery route. Delicate formulations like liposomes are inherently unsuitable for this delivery model as they are delicate biomaterials incapable of withstanding shear stress. When encapsulated within a crystalline and rigid coating made of zeolitic imidazolate frameworks, the liposomes are not only protected from thermal stress but also shear stress. The protection from shear stress is crucial, especially for formulations with cargo encapsulated inside the lumen of the liposomes. Moreover, the coating provides the liposomes a solid, rigid exterior which allows the particles to penetrate the tissue model and porcine tissue effectively.
Common Trends of Chiral Induced Spin Selectivity and Optical Dichroism with Varying Helix Pitch: A First-Principles Study
Authors: Herrmann Carmen , Saghatchi Aida , Mujica Vladimiro , Naskar Sumit
Published: August 2022

Electrons transported through a chiral molecule become spin-polarized; this phenomenon is known as chiral induced spin selectivity (CISS). It has implications for spintronics, for electrochemical and enantioselective reactions, and for electron transfer in biological systems. The CISS-induced spin polarization in simulations and in experiment differs by orders of magnitude, and the detailed underlying mechanism is still an open question. Structure-property relationships can help elucidate this question. For this purpose, the effect of helix pitch is studied for a model helix of 20 carbon atoms for two quantities that have been found to correlate in some experiments: spin-polarization in transmitted electrons and electronic circular dichroism (ECD). We find that even though the chirality of these model helices goes down with increased pitch, ECD and CISS go up, along with UV-Vis and magnetic and electric transition dipole moments. Orbital contributions to the most intense UV-Vis transition do not show a consistent qualitative picture. Tentatively, we can assign the increase in these properties to an increase of the electric polarizability with the spatial extension of these helices by changing pitch.
Developing Teacher Identity while Creating Culturally Authentic Materials
Authors: Byrd David
Published: August 2022

Teacher candidates enter teacher education programs as part of the process of becoming professional educators. As they progress through these programs, their thinking and beliefs about teaching and being a teacher are supported or challenged and their professional identity is developed. Traditionally, these programs provide course work and practica aimed towards learning theory and practical knowledge, but these and other opportunities can influence teacher candidates’ subsequent identity development as well. This study looked at the professional identity development of three teacher education students, who created culturally authentic stories and educational materials for students in Thailand. Using grounded theory, various data sources were triangulated to discover if the teacher education students developed their professional identity in an ‘other space.’ Results showed that ample opportunities were provided to express, examine, and adjust how the teacher candidates see themselves as emerging professionals in the classroom.

Authors: Zulkifli Zuliana Azwa , Ahmad Farouk Azeem Fazwan , Abang Ali Dayang Haszelinna , Mokhtar Norhayati
Published: August 2022

This study refining the dengue vulnerability assessment using DVFM to describes the vulnerability of dengue in Malaysia during the period of 15 years to identify high-low risk areas among sample of studies (except Wilayah Persekutuan Putrajaya). The dengue reported cases in Malaysia were analyzed using the data provided by the Disease Control Division Vector, Ministry of Health Malaysia (MOH) from 2003-2017. As per literature, factors influencing the vulnerability to infectious disease outbreak were identified as population density, urbanization, medical care workforce, medical care infrastructure, public health delivery, safe water and sanitation as well as economic strength. This framework was tested using empirical cases of dengue outbreak in Malaysia. The dataset used was obtained from widely available data (from the Department of Statistics Malaysia (DOSM) and Health Indicator Report by MOH). From 2003-2017, 829, 299 cases have been reported in Malaysia. The highest number was recorded in 2015 (63198, Selangor). The key findings from this assessment included the states with their vulnerability and actual dengue reported cases. The results also concluded that the framework prediction did not match the actual outbreak reported.  Recently in Malaysia, the reported cases have increased steadily in most areas. The surveillance and control strategies should be strengthened especially for areas with the most vulnerable to dengue outbreak without deprioritizing the least vulnerable state. Further research should be conducted to explore other drivers that may reflect the vulnerability of dengue outbreak.

Published: August 2022

Предложен простой способ модификации параметров поля сил при молекулярно-динамическом моделировании водных растворов спиртов при изменении концентрации. На примере метанола, этанола, 1- и 2-пропанола удалось существенно улучшить описание экспериментальной плотности растворов по сравнению с использованием стандартного поля сил OPLS-AA. Показано, что для этого достаточно изменять величины зарядов на молекулах спирта линейно с концентрацией. Для полученных моделей рассчитаны объемные характеристики растворов, которые также хорошо совпадают с экспериментальными. В частности, удается количественно воспроизвести минимумы на кривых кажущегося и парциального мольных объемов, характерные для рассмотренных спиртов в области малых концентраций.

Authors: Ifeanyi Johnson Onyekpa  , Boniface Uwaezuoke Odugu  , Chukwunonso Nnabuike Ofonere
Published: August 2022

Background: Caesarean delivery or abdominal delivery is a common intervention in current obstetric practice which has significantly reduced maternal and neonatal morbidities and mortality. The World Health Organization (WHO) in 1985 pegged the acceptable rate at 10-15% but the rate of caesarean sections has been increasing in both the developed and developing countries. However, the rates have been exceeded in many developed countries while in the developing countries with a lot of unmet needs, the rates are quite low. When absolutely indicated, the rate should not prevent the timely recourse to the procedure which is life-saving. Aim: The aim was to determine the rate of caesarean section in ESUT Teaching Hospital over t a 3-year period. Materials and Method: This was a retrospective study of all the caesarean sections done in ESUT Teaching Hospital Enugu from December 31, 2020 to January 1, 2018. The necessary data was collected from the registers of the theatre and labour ward of ESUT Teaching Hospital and patients’ case notes using a structured proforma. Statistical Analysis: Data collected from the study was analyzed with the Statistical Package for Social Sciences (SPSS) computer software for Windows version 20.0. Results were presented using simple percentages, frequencies and tables.

Stroke is one of the second most significant causes of death and the second highest cause of disability globally, 87% of which are ischemic strokes (IS). Blood glucose levels are known to have a relationship with the clinical outcome of IS patients as measured by the National Institutes of Health Stroke Scale (NIHSS). This study aims to determine the relationship between the patient's plasma blood glucose level upon hospital admission and the IS patient's severity. This research is a cross-sectional analytic study using medical records of IS patients hospitalized at the Neurology Department of RSUD Dr. Soetomo Surabaya between January 2019 and December 2020. Sampling was carried out using a total sampling technique, including patients with the diagnosis of an IS aged ≥18 years old. Patients with a diagnosis of ICH, SAH, TIA, and patients with a history of CHD were excluded from this study. We analyzed medical record data by Chi-Square statistical test on blood glucose and clinical outcomes of patients with NIHSS. In total, 53 out of 89 medical records met the inclusion criteria. Random; fasting; and 2 hours post-prandial blood glucose levels on IS patients in admission to the hospital showed a non-significant relationship with p=0.764; p=0.130; p=0.210 (p>0.05) with a weak correlation value to the clinical severity of patients as measured by NIHSS. Blood glucose levels at hospital admission cannot be the sole predictor in determining the clinical severity of IS patients using the NIHSS. Many other co-factors affect the clinical severity of the patient.

Pain is a common unpleasant sensory and emotional experience, in which are frequently used in their treatment the nonsteroidal anti-inflammatory drugs (NSAIDs). A group of agents with antipyretic, analgesic, and anti-inflammatory properties due to the inhibition of cyclooxygenase enzymes (COXs). Among these drugs there are a group of selective inhibitors of COX-2 named coxib that include to parecoxib, celecoxib, rofecoxib and etoricoxib. Pharmacological information on the mechanism of action of coxibs is insufficient to determine the analgesic and anti-inflammatory efficacy of these agents. There are contradictory reports regarding the antinociceptive effects of the various coxibs at the preclinical level as well as the nitridergic modulation of such actions. The objective of the present study was to evaluate the antinociceptive efficacy of parecoxib, rofecoxib, celecoxib, and etoricoxib using the formalin hind paw assay in mice and the possible contribution of the nitridergic system in the efficacy of COX-2 agents. Antinociception was assessed in a murine formalin assay using dose-response curves to coxibs before and after i.p. administration of 5 mg/kg of L-NAME. Coxibs produced dose-dependent analgesia and anti-inflammation. L-NAME administration reduced the analgesic and anti-inflammatory effectiveness of parecoxib, rofecoxib, celecoxib, and etoricoxib. These findings suggest that the effect of these agents, in addition to COX-2 inhibition, would be mediated by other mechanisms, among which nitridergic modulation would be compromised.

The exenoration clause is an exclusion / liability exclusion clause in a housing sale and purchase agreement. The purpose of writing this scientific article is to find out the accountability of business actors for offers submitted to prospective consumers and restrictions on the inclusion of standard clauses containing exenoration clauses in the offer of buying and selling houses as a legal protection effort for consumers. The results of the study indicate that the treaty law in Indonesia essentially assumes that brochures have binding legal force. This binding strength is based on the fact that the brochure is a binding form of supply as specified in the Consumer Protection Act which is based on the principle of good faith at the pre-contractual stage. Judging from the freedom of contract the standard agreement with an exoneration clause does not meet the subjective and objective requirements as specified in Article 1320 BW, thus the exoneration clause stated by the business actor in the brochure as a bidding instrument does not have binding power. Provisions for transferring accountability, actions in the form of business actors are not responsible for changes in specifications contained in brochures violating Article 18 paragraph (1) letters a, c, and d of Consumer Protection Act. And has an effect on null and void (nietig / null and void).

Manajemen laba penting untuk diperhatikan, karena akan berdampak langsung pada persuahaan. Free cash flow, profitability, dan audit quality diyakini sebagai indikator manajemen laba perusahaan. Sampel dari penelitian ini yaitu 30 perusahaan manufaktur yang terdaftar di Bursa Efek Indonesia (BEI) periode 2015-2019. Teknik analisis yang digunakan adalah regresi data panel. Hasil penelitian menunjukkan adanya pengaruh simultan ketiga variabel independen terhadap variabel dependen. Secara parsial, hanya variabel free cash flow yang berpengaruh terhadap earnings management. Siginifikansi free cash flow mengindikasikan bahwa pengelolaan arus kas yang dilakukan oleh manajer akan memberikan dampak positif terhadap perusahaan seperti menarik minat investor untuk melakukan investasi. Di sisi lain, profitabilitas dan kualitas audit membuktikan bahwa investor terkadang tidak memperhatikan ke duanya sebagai indikator penentu dalam melakukan investasi.
