Volatile Oxidation Products and Secondary Organosiloxane Aerosol from D5 + OH at Varying OH Exposures
Authors: Kang Hyun Gu , Chen Yanfang , Jeong Jiwoo , Park Yoojin , Berkemeier Thomas , Kim Hwajin
Published: June 2023

Abstract. Siloxanes are composed of silicon, oxygen, and alkyl groups and are emitted from consumer chemicals. Despite being entirely anthropogenic, siloxanes are being detected in remote regions and are ubiquitous in indoor and urban environments. Decamethylcyclopentasiloxane (D5) is one of the most common cyclic congeners, and smog chamber and oxidation flow reactor (OFR) experiments have found D5 + OH to form secondary organosiloxane aerosol (SOSiA). However, there is uncertainty about the reaction products, and the reported SOSiA mass yields (YSOSiA) appear inconsistent. To quantify small volatile oxidation products (VOP) and to consolidate the YSOSiA in the literature, we performed experiments using a Potential Aerosol Mass OFR while varying D5 concentration, humidity, and OH exposure (OHexp). We use a proton transfer reaction time-of-flight mass spectrometer to quantify D5, HCHO, and HCOOH, and detect other VOP, which we tentatively identify as siloxanols and siloxanyl formates. We determine molar yields of HCHO and HCOOH between 52 – 211 % and 45 – 127 %, respectively. With particle size distributions measured with a scanning mobility particle sizer, we find YSOSiA to be < 10 % at OHexp < 1.3 × 1011 s cm-3 and ~20 % at OHexp corresponding to that of the lifetime of D5 at atmospheric OH concentrations. We also find that YSOSiA is dependent on both organic aerosol mass loading and OHexp. We use a kinetic box model of SOSiA formation and aging (aging-VBS model) to reconcile the YSOSiA values found in this study and the literature. The model uses a volatility basis set (VBS) of the primary oxidation products as well as an aging rate coefficient in the gas phase, kage,gas, of 2.17 × 10-11 cm3 s-1, and an aging rate coefficient in the particle phase, kage,particle, which is ten times smaller. The combination of primary VBS and OH-dependent oxidative aging predicts SOSiA formation much better than a standard-VBS parameterization that does not consider aging (R2 = 0.970 vs. 0.847). The need for an ageing-dependent parameterization to accurately model SOSiA formation shows that concepts developed for secondary organic aerosol precursors, which are able to form low-volatile products at low OHexp, do not necessarily apply to D5 + OH. The resulting yields of HCHO and HCOOH and the parameterization of YSOSiA may be used in larger scale models to assess the implications of siloxanes on air quality.
Uncertainties, complexities and possible forecasting of the volcán de Colima energy emissions (México, years 2013–2015) based on the fractal reconstruction theorem

Published: June 2023

Abstract. A time series of effusive-explosive volcanic emissions of energy by the volcanic activity in Volcán de Colima (Western segment of Trans-Mexican volcanic belt, years 2013–2015) is analysed from the point of view of the reconstruction theorem, being considered several fractal computational procedures, such as the Hurst exponent (persistence, anti-persistence or randomness of the series), Lyapunov exponents and Kaplan-Yorke dimension (degree of forecasting difficulty on the series of energy emissions) and the correlation integral of the series, being obtained the Kolmogorov entropy and the embedding dimension (quantification of the degree of complexity and “loss of memory” of the physical mechanism along an episode of volcanic emissions). The analysed series have been chosen by applying the Gutenberg-Richter law to the logarithm of the complete energy emissions, being discarded those not accomplishing the mentioned law. Definitively, a series of 6182 explosive events and its seismic energy along years 2013–2015 has been selected. The reconstruction theorem algorithm is applied to the whole emission series, to 6 consecutive segments of 1000 emissions and to 21 moving window series of 2000 data lengths and shifts of 200 data, being also introduced and validated some examples of a nowcasting strategy. The main objective of this paper is to quantify the complexities concerning the physical and mathematical mechanisms governing these emissions, which are necessary for possible forecasting of explosive volcanic energy emissions with an enough degree of certainty.
Technical note: in-situ measurements and modelling of the oxidation kinetics in films of a cooking aerosol proxy using a Quartz Crystal Microbalance with Dissipation monitoring (QCM-D)

Published: June 2023

Abstract. Aerosols and films are found in indoor and outdoor environments. How they interact with pollutants, such as ozone, has a direct impact on our environment via cloud droplet formation and the chemical persistence of toxic aerosol constituents. The chemical reactivity of aerosol emissions is typically measured spectroscopically or by techniques such as mass spectrometry, directly monitoring the amount of material during a chemical reaction. We present a study which indirectly measures oxidation kinetics in a common cooking aerosol proxy using a low-cost Quartz Crystal Microbalance with Dissipation monitoring (QCM-D). We validated this approach by comparison with kinetics measured both spectroscopically and with high-intensity synchrotron radiation. Using microscopy, we found that the film morphology changed and film rigidity increased during oxidation. There was evidence of surface crust formation on oxidised particles, though this was not consistent for all experiments. Crucially, our kinetic modelling of these experimental data confirmed that the oleic acid decay rate is in line with previous literature determinations, which demonstrates that performing such experiments on a QCM-D does not alter the underlying mechanism. There is clear potential to take this robust and low cost, but sensitive method to the field for in-situ monitoring of reactions outdoors and indoors.
A model instability issue in the National Centers for Environmental Prediction Global Forecast System version 16 and potential solutions
Authors: Zhou Xiaqiong , Juang Hann-Ming Henry
Published: June 2023

Abstract. The National Centers for Environmental Prediction (NCEP) Global Forecast System version 16 (GFSv16) encountered a few model instability failures during
the pre-operational real-time parallel runs. The model forecasts failed when an extremely small thickness depth appeared at the model's lowest layer
during the landfall of strong tropical cyclones. A quick solution was to increase the value of minimum thickness depth, an arbitrary parameter
introduced to prevent numerical instability. This modification solved the model's numerical instability with a small impact on forecast skills. It
was adopted in GFSv16 to implement this version of the operational system as planned. Upon further investigation, it was determined that the extremely thin depth was a result of the advection of geopotential heights at the interfaces of
model layers. In the Finite-Volume Cubed-Sphere (FV3) dynamical core, the horizontal winds at interfaces for advection are calculated from the layer-mean values by solving a tridiagonal system of equations in the entire vertical column based on the parabolic spline method (PSM) with high-order boundary conditions (BCs). We replaced the high-order BCs with zero-gradient BCs for the interface-wind reconstruction. The impact of the zero-gradient BCs was investigated by
performing sensitivity experiments with GFSv16, idealized mountain ridge tests and the Rapid Refresh Forecast System (RRFS). The results showed that zero-gradient BCs can fundamentally solve the instability and have little impact on the forecast performances and the numerical solutions of idealized mountain tests. This option has been added to FV3 and will be utilized in the GFS (GFSv17/Global Ensemble Forecast System version 13 – GEFSv13) and RRFS for operations.

Cost overruns in building projects are typical in India. This might occur owing to a variety of factors. The aim of the study was to identify the factors impacting high-rise housing project costs in India, that are likely regulatable by head contractors. A questionnaire survey was used to perform this study with a group of related professionals from firms in the private as well as public sectors, having experience in high-rise housing projects. The frequency and impact of each factor were assessed based on the perspectives of the participants. The factors were then rated in order of the increasing Index of Relative Importance. The study identified significant factors that are likely to be regulated by head contractors, namely, productivity of labor, the performance of suppliers and sub-contractors, productivity of equipment, poor management of the site, scheduling, controlling and monitoring, inexperienced project managers, ineffective procurement planning of materials, ineffective procurement of equipment, delivery of materials (shortage or delay) and shortage of skilled labor.
Etika Bisnis Islam dalam Praktik Pengembalian Uang Belanja Konsumen (Studi Kasus di Atakana Swalayan Pangkalan Brandan Kabupaten Langkat)
Authors: Sakinah Sakinah , Safarida Nanda
Published: June 2023

Penelitian ini bertujuan untuk menganalisis praktik pembelanjaan belanja konsumen di supermarket Atakana Pangkalan Brandan Kabupaten Langkat dan menganalisis praktik pembelanjaan konsumen dari sudut pandang etika bisnis islami. Jenis penelitian yang digunakan dalam penelitian ini adalah penelitian lapangan, yang dilakukan dengan cara mengumpulkan data dan informasi yang diperoleh langsung dari informan dan responden serta observasi secara langsung. Dalam praktek pengembalian uang konsumsi konsumen dengan ditukar dengan barang ada beberapa yang menyatakan tidak terpenuhinya akad dan belum diambilnya objek tertentu, artinya pembelian telah terpenuhi namun sama dengan pengembalian uang belanja konsumen dalam penukaran permen yang belum terpenuhi, karena tidak adanya akad atau lafadz yang mengatakan kasir mengganti uang receh dengan permen. Dan konsumen tidak diberi kesempatan untuk menyepakati ganti-ganti barang karena kasir dengan seenaknya menyerahkan candy bar tersebut. Berdasarkan hasil penelitian, praktek pengalihan sisa uang yang dihabiskan dengan permen ini dilakukan karena sulitnya mendapatkan kembalian nominal yang rendah, yang dilakukan oleh supermarket Atakana Pangkalan Brandan. Dalam Islam seharusnya dilakukan secara transparan dan tidak menghakimi, namun pada kenyataannya perubahan yang dilakukan tanpa persetujuan salah satu pihak dan hanya menguntungkan satu pihak dan dapat merugikan pihak lainnya. Pengembalian nominal konsumsi konsumen, merupakan hak konsumen dan tidak boleh ditukar tanpa persetujuan konsumen. Dalam hal ini terdapat praktek mengambil hak orang lain dan saling menghakimi.

Any costs allocated by farmers will directly affect the amount of revenue and the level of income or profits of farmers. The thing that must be understood is to find out the size of the costs incurred in farming each planting season, it takes a source of information related to the costs incurred, selling prices and the amount of production in farming. The source of information referred to is farming bookkeeping, farming bookkeeping will provide information for farmers about the development of farming activities every planting season. In explaining their farming, the participants never took notes and even compiled books in their farming. farmers in Koya Koso generally do not manage their farming costs well. Farmers understand that land preparation costs and planting costs are the total costs or total costs in farming. While the cost of using tools in farming needs to be taken into account, because basically the tools used in farming have a limited economic life. After farmers understand and are able to distinguish between fixed costs and variable costs in farming, the next activity is to provide training to farmers to calculate the amount of revenue and income. In general, farmers consider the value of the sale is the net profit received in one growing season. So this training provides an understanding to farmers about the differences in income and income.Keywords: Competence, management, farming, farming bookkeeping

¿Es el cine una simulación falaz? Relaciones entre cine y verdad desde el materialismo filosófico
Authors: Morala Girón Alejandro
Published: June 2023

La reflexión en torno a la ontología del cine ha sido una preocupación básica en las teorías fílmicas desde sus orígenes (Casetti, 1994). Sin embargo, las relaciones entre cine y verdad solo pueden abordarse desde un sistema filosófico que analice la estructura tecnológica del dispositivo cinematográfico. En el presente artículo asumimos las coordenadas del materialismo filosófico de Gustavo Bueno (2018) para criticar la consideración del cine como simulación falaz. Confrontando posiciones realistas e idealistas, definimos el cine como una representación indeterminada cuya verdad puede constituirse dialógicamente.
Retórica de la columna personal: el artículo semanal de Manuel Jabois y Leila Guerriero en “El País”
Authors: Gómez-Calderón Bernardo , Bryan-Rodríguez Mercedes
Published: June 2023

En este trabajo, se analizan las características del columnismo de Leila Guerriero y Manuel Jabois de acuerdo con los postulados de la Teoría de la Argumentación. Aplicando el análisis retórico y contemplando las cuatro fases de elaboración del discurso persuasivo (intellectio, inventio, dispositio y elocutio), se determinan tanto similitudes como divergencias entre ambos articulistas. Los dos abordan principalmente temas de índole personal y social en sus textos, recurren con frecuencia al ethos, al logos, a los argumentos por analogía y de autoridad, y se decantan sobre todo por la macroestructura inductiva. En cuanto a las divergencias, Jabois despliega un abanico más variado de temas en sus columnas, mientras que Guerriero recurre en mayor medida a la argumentación por generalización y se sirve más profusamente del lenguaje figurado, en especial de la metáfora.

Authors: Castells-Fos Llúcia , Lopezosa Carlos , Pont-Sorribes Carles , Codina Lluís
Published: June 2023

El objeto de estudio es la operacionalización de tres conceptos clave para la sostenibilidad de los medios de comunicación en el entorno digital: la reputación, la visibilidad y la fidelización de la audiencia. Se ha analizado la visión de expertos y académicos para validar su pertinencia y potencial operativo con la administración de un cuestionario semiestructurado. La reputación se percibe como un activo esencial. La visibilidad y la fidelización deben trabajarse siguiendo unas técnicas ya probadas en otras actividades económicas con problemáticas similares. En cuanto a su medición, los expertos recurren a las métricas clásicas del ámbito publicitario, pero también a técnicas cualitativas irrenunciables a la hora de analizar la reputación. Mientras la reputación y la fidelización comparten elementos como la calidad, la credibilidad y la orientación a la audiencia, la visibilidad destaca por ser condición necesaria pero insuficiente a la hora de garantizar la viabilidad del medio de comunicación

Periodismo en duelo: adaptación al entorno digital en Chile a partir de la crisis social y la pandemia de COVID-19
Authors: Grassau Daniela , Ortega-Gunckel Constanza , Puente Soledad
Published: June 2023

Este trabajo estudia cómo dos importantes crisis, el estallido social de 2019 y la pandemia de COVID-19, influyeron en la adaptación del periodismo chileno a los desafíos del entorno digital. Para ello, se utilizó un enfoque cualitativo basado en 41 entrevistas en profundidad a periodistas en ejercicio durante ambos sucesos, seguidas por 50 entrevistas a editores de medios tradicionales y alternativos que reflexionaron retrospectivamente sobre las consecuencias de estos eventos para la profesión. El análisis permitió concluir que el periodismo chileno experimentó en los últimos cuatro años etapas similares a las de un duelo: negación, ira, negociación, depresión y aceptación. Tanto el estallido social como la pandemia aceleraron los procesos de modernización y adaptación a las nuevas tecnologías por parte de las salas de prensa chilenas y, al mismo tiempo, obligaron a los profesionales a repensar y resignificar los alcances del periodismo como profesión.

Published: June 2023

This study aims to check the relationship between TAM factors and purchase intention, having the mediating role of technological information. Research is being conducted to determine how Covid 19 affects consumer purchase intentions. Investigation shows that around the world, there has been an agenda to inspect TAM factors and how they impacted purchasing behaviours because of Covid. Individuals move towards web-based shopping as they effectively embrace early adopter conduct and move towards innovation. They need to look at whether they will be severe towards the creation of internet shopping in post-pandemic time. Data was collected through structured questionnaires and analyzed through Smart Pls. Consumer shopping behaviour, the theory of planned behaviour, supports our research questions. There is a positive mediation relationship between TAM factors and CPI during Covid 19, but before COVID-19, mediation fails. The prime focus of this study is to investigate behavioural change of customers due to the pandemic, which is helpful for strategy makers to formulate new strategies according to new norms of society.

Published: June 2023

Padi straw (Oryza sativa) is one type of stem produced from padi tree trunks. Antibacterial activity testing was carried out by agar diffusion method using paper disc as a backup by observing the formation of a clear zone indicating the presence of antibacterial activity. Variations in the concentration of the padi straw extract test solution were made with a %w/v ratio between 100% pure padi straw extract and DMSO adjusted at various test concentrations, namely, 5%, 10%, 15%, 20%, and 25%. The results showed that the n-hexane fraction of padi straw did not have antibacterial activity because there was no inhibition zone or kill zone indicated by the fraction at both low and high concentrations. While the ethanol extract showed antibacterial activity at a concentration of 15%, the ethyl acetate fraction and the n-butanol fraction had antibacterial activity indicated by the presence of an inhibitory zone at a concentration of 7%. The results of the t-test on the ethanol extract of the test bacteria obtained a Tcount value of 14,687 which means it is very significant or very significantly different because Tcount is greater than Ttable (5% and 1%). This shows that the oxytetracycline antibiotic is better than the potency of the ethanol extract of straw on the test bacteria.

Renal hemodynamics in patients with arterial hypertension. (Literature review)
Authors: Cociu Maria
Published: June 2023

Despite the obvious progress, the diversification of therapeutic possibilities and countless studies, hypertension is still often difficult to control. Unfortunately, the frequency of cases in which blood pressure does not reach the guideline targets is very high globally. The challenging concept of resistant hypertension represents a difficult situation in the practical approach. Being simultaneously a disease and a reducible risk factor for major cardiovascular events, we can point out that the correct approach to resistant hypertension marks one of the major goals in cardiology. Recent studies highlight the importance of the renal hemodynamics of the hypertensive patient with possible assessment of the evolution over time of renal function, target organ damage and the response to hypotensive treatment. Thus, both from a scientific point of view and for practical medicine, the identification of the peculiarities of renal hemodynamics in hypertensive patients resistant to treatment is of particular interest
Pulmonary embolism associated with acute ST-segment elevation myocardial infarction
Authors: Grosu Aurel , Dabija Valeria , Esanu Andrei
Published: June 2023

Pulmonary embolism (PE) is a potentially fatal condition that presents with shortness of breath and chest pain. Although an electrocardiogram (ECG) may show changes associated with PE, ST elevation mimicking ST elevation myocardial infarction is not common in patients with acute PE. This presentation documents the case of a 67-year-old man who presented to the emergency department with dyspnea and chest pain. ECG data indicated anterior septal myocardial infarction and acute ischemia of the lower parts of the left ventricle. Cardiac catheterization did not reveal atherosclerotic lesions of the coronary arteries, but revealed an anomaly in the filling of the right coronary artery with embolic masses. Further examination of the patient revealed massive bilateral pulmonary embolism. In this presentation, we emphasize the need to evaluate patients with PE who present with chest pain, dyspnea, or both, even when ECG findings suggest a cardiac etiology. We also present a brief discussion of possible mechanisms for ST elevation in pulmonary embolism

يعَدُّ الإمام مالك بن دينار من أئمة الزهد في عصر التابعين، وكانت له طريقته الخاصة في الزهد والسلوك وتزكية النفس، حتى عُرف بها مما جعلها تهيمن على سائر اختصاصاته. هدفتْ هذه الدراسة إلى التعريف بالإمام مالك بن دينار تعريفا توثيقيا من حيث حياته ومكانته العلمية، وكشف الجانب الحديثي لديه؛ ومن ثم التوصل إلى مدى الترابط والعلاقة بين أصحاب الزهد ورواية الحديث وإسناده. والمنهج في هذه الدراسة هو المنهج التاريخي والاستقرائي، حيث تمت دراسة حياة الزاهد مالك بن دينار وكشف الجانب الحديثي لديه ومكانته العلمية. وتوصلت الدراسة إلى عدة نتائج مهمة متمثلة في أن الإمام مالك بن دينار كان إماما زاهدا صدوقا من ثقات التابعين، وأنه كان مقلا في إسناد الحديث وروايته، وأن أحاديثه في درجة الحسن، وأن ما روي عنه من أحاديث لا تصح، فليس هو السبب فيها، وإنما الحَمْل على بعض من يروي عنه من غير الثقات.

Despite efforts to restore land and fight food insecurity, sustainable land management (SLM) technologies are not yet widely adopted in developing countries. This article reviews and synthesizes studies that have been conducted in developing countries over the last few decades. A total of 145 documents were used in this synthesis. A key finding of this paper is the identification of a theoretical gap that provides information for future studies on SLM practices.Another one is that, studies focusing on adoption in this synthesis have not considered awareness of technology as a key part of the adoption process. Most econometric studies focus on econometric regression and consider SLM adoption as a dichotomous choice. The use of mathematical models such as existing dynamic Discrete Stochastic Programming (DSP) models could provide more robust results to overcome this limitation observed in statistical regression results. Additionally, it would be interesting to analyze smallholder farmers’ preferences for SLM practices because very little is currently known about their preferences.

The purpose of this study was to investigate the effectiveness of the integration program for transition from discharge preparation to home-based medical care. A total of 341 referrals to home-based medical care services were recommended based on the integration program at a regional hospital in northern Taiwan from March 2018 to December 2021. Statistics showed that the rate of holding transdisciplinary meetings for discharge preparation during hospitalization was 75%. The rate of successful referrals was 83.9%, and the rate of readmission within 14 days was 1.2%. 35 (10.3%) of the patients agreeing to the referral also received long-term care assessment at the hospital, and 33 (9.7%) were recipients of advanced home-based medical care. With the transdisciplinary meetings coordinated by the discharge preparation service team to integrate and refer resources, the patient-centered integration program is capable of helping disabled patients receive needed long-term care assessment and home-based medical care services in the different stages of their illness after returning to the community.

 
歌仔戲《三進士》版本比較與演繹分析——兼論傳統劇本所展現的現代風貌

《三進士》故事的來源與底本無法考證，但其早年曾在臺灣各劇種間流行，留下演出紀錄與影音資料。由於此故事在臺灣以歌仔戲留存的影音資料較多，因此藉由現存資料：1968年由五虎唱片發行的黑膠唱片錄音檔案、2012年河洛歌子戲團錄製的電視歌仔戲影音檔及2019年薪傳歌仔戲劇團現代劇場演出錄製的影音檔，進行分析比較。除了了解此故事如何在三個不同年代，且演繹方式極為不同的版本間搬演。也探究老戲如何在現代社會中新做，將傳統劇本中不合情理的情節合理化，並融合當代思維與原本教忠教孝的主題思想，產生新風貌。

O presente trabalho teve por objetivo propor um IQA para as águas ácidas de Manaus usando estatística multivariada. Foi escolhido um local isolado dos grandes centros urbanos para servir de background natural da região. Foram realizadas coletas mensais de água neste igarapé entre os meses de janeiro e julho de 2022 a fim de estabecer marcadores ambientais de naturalidade. Analisou-se 22 variáveis ambientais, e, em seguida, se utilizou a Análise da Componente Principal – ACP para estabecer as variáveis mais importantes do conjunto de dados. Os resultados apontaram que as variáveis que mais se destacaram foram Ntotal, Cl-, Na+ e condutividade elétrica. A ACP também identificou influência moderada das variáveis NH4+, K+, PO43- e coliformes fecais na compoisção das águas. Criou-se categorias de águas com base em equações exponenciais e logarítimicas despontadas pelas medidas realizadas. Por fim, as equações e curvas foram aplicadas em 12 corpos de água distribuídos na área urbana de Manaus e demonstraram que 75% das amostras avaliadas estavam na condição de péssima.

In this study, the effects of three different bacterial isolates added to the vase solution on the vase life were investigated. All three bacterial isolates significantly increased the vase life of gerbera cut flowers. While the vase life of the flowers in the control solution was 3 days, this period reached up to 11 days in the flowers kept in the vase containing bacteria. Daily water uptake decreased with increasing time in vase in all treatments. Although there were some differences between treatments in terms of daily water uptake, it has been determined that bacteria application does not have a significant effect on water uptake. The relative fresh weight decreased with increasing time in the vase. For example, in the solution containing Z7 bacteria, which allows the flowers to live the longest, the flower weight, which was 89 g on August 11, decreased day by day and decreased to 68 g on August 23. Bacteria applications slowed the rate of decrease in fresh weight. Bacillus cereus found to be more effective than other bacterial isolates in slowing fresh weight decrease.

The emergence of regulations governing the use of loudspeakers in mosques seems to have caused a lot of controversy, especially when there was a statement from the Chief Minister of Religion Yaqut Cholil Qoumas. This polemic certainly gets a lot of attention from various news media by way of reporting that is in accordance with the ideology and interests of the media. Every news text contained in print media, as well as online is the result of construction by framing the point of view of an event. This study aims to find out the construction of accurate.co news regarding the Minister of Religion's rules regarding loudspeakers in mosques. Which parts will be eliminated and highlighted by Akurat.co to convey the reality of the news that has been constructed. This study uses the constructivism paradigm with the Zhong Dang Pan and Gerald M. Kosicki model media framing analysis method. This framing analysis model is divided into four analysis structures, namely: syntactic structure, script structure, thematic structure, and rhetorical structure. This study found that there was news framing that led to the element of media Accuracy.co's partiality towards the Ministry of Religion's regulations regarding the rules for loudspeakers in mosques. The construction of reality in the news text carried out by the media accurate.co was carried out as an effort to direct public opinion that Yaqut Cholil Qoumas' statement as chief minister was not to compare the sound of the call to prayer and the sound of dogs barking, but as an example that loud noises can disrupt tolerance in social life.
