Published: June 2023

The adsorption of Cibacron Brilliant Yellow (CBY) 3-GP dye onto TiO2 Degussa, Fe2O3, and TiO2 anatase/Diphenylcarbizide in aqueous solution was studied with respect to temperature, contact time, and pH. The CBY 3-GP adsorption at equilibrium increased as the initial dye concentration increased for TiO2/DPC, while it decreased for TiO2 Degussa; however, it increased the initial dye concentration. The best removal efficiency was obtained at 1 mg for TiO2/DPC, TiO2 Degussa, and the amount of adsorption decreases with the rising of temperature. The negative ΔH° reveals the adsorption is exothermic and extremely negative ΔS° for TiO2 Degussa. The negative value for ΔS° indicates a regular increase of the randomness at the TiO2/DPC and Fe2O3 solution interface during adsorption. The intraparticle diffusion, pseudo-first- and second-order kinetic models were used. The Langmuir, Temkin, Freundlich, and Dubbin adsorption models were examined to describe the equilibrium isotherms. The usage of TiO2 Degussa and TiO2/DPC indicates that the equilibrium sorption was favorable.

Published: June 2023

The purification of terephthalic acid recovered from an alkali-reduction wastewater by reactive crystallization was investigated. The crude terephthalic acid was reacted with sodium hydroxide solution to form a salt of disodium terephthalate, then acidified with sulfuric acid to get the terephthalic acid with higher purity. Effects of time, pH, concentration, and flow rate of secondary feed solutions, temperature, and stirring rate on Crystal Size Distribution (CSD) of terephthalic acid precipitate were investigated. The results showed that CSD was influenced by the concentration of reactants and the pH solution. On the other hand, time, temperature, flow rate of secondary solution, and stirring rate had no significant effects on the CSD, which the mean size of crystals ±3 μm. The mean size of crystals at solution pH 5, 4, and 3 were 6.03, 9.42, and 10.34 μm, respectively; meanwhile, at concentrations of 0.5, 0.3, and 0.1 M, were 7.57, 3.24, and 3.09 μm, respectively. The semi-batch reactive crystallization with double-feeding at constant pH and temperature produced monodispersed crystals. However, this method needs to be carried out more than once for terephthalic acid purification, which is intended for polyethylene terephthalate (PET) polymerization.

NOAA Climate Prediction Center (CPC) has generated a 100-member ensemble
of Atmospheric Model Intercomparison Project (AMIP) simulations from
1979 to present using the GFSv15 with FV3 dynamical core. The intent of
this study is to document a development in an infrastructure capability
with a focus to demonstrate the quality of these new simulations is on
par with the previous GFSv2 AMIP simulations. These simulations are part
of CPC’s efforts to attribute observed seasonal climate variability to
SST forcings and get updated once a month by available observed SST.
The performance of these simulations in replicating observed climate
variability and trends, together with an assessment of climate
predictability and the attribution of some climate events is documented.
A particular focus of the analysis is on the US climate trend, Northern
Hemisphere winter height variability, US climate response to three
strong El Niño events, the analysis of signal to noise ratio (SNR), the
anomaly correlation for seasonal climate anomalies, and the South Asian
flooding of 2022 summer, and thereby samples wide aspects that are
important for attributing climate variability. Results indicate that the
new model can realistically reproduce observed climate variability and
trends as well as extreme events, better capturing the US climate
response to extreme El Niño events and the 2022 summer South Asian
record-breaking flooding than GFSv2. The new model also shows an
improvement in the wintertime simulation skill of US surface climate,
mainly confined in the Northern and Southeastern US for precipitation
and in the east for temperature.

Published: June 2023

Financial well-being (FWB) refers to a status of an individual equipped with adequate resources to live life comfortably. Millennials, a cohort born in 1980-2000, fared less well financially than other generations. This article attempted to look into the existing body of knowledge to provide a comprehensive understanding of the factors affecting FWB among millennials. Employing a combined PICO and SPIDER tools, fifteen articles have been identified and subsequently, five themes were developed affecting FWB among millennials such as financial behavior and financial literacy, personal traits, social and economic environment, and life stage attributes. Among these identified factors, financial literacy is considered to be the strongest as higher financial literacy translates into better handling of finances, resulting in surplus and therefore better FWB. Financial behavior and financial attitude are also important as they involve skills, motivation, and confidence to apply knowledge and understanding. Personality traits equally remained as strong predictors along with social and economic environment factors as well as social support from firms and institutions which significantly affect financial well-being. This research will enable millennials to improve their financial lives. In the pursuit of improving their financial well-being, individuals make financial decisions to grow their assets and protect their resources and alleviate financial crises. Overall, this paper has demonstrated the factors that substantially determine FWB among millennials. It is recommended that relevant research be done to verify the factors identified in this study.
Seeking an ‘Ideal Place’ in a Nuosu Origin Epic
Authors: Bender Mark 
Published: June 2023

Abstract
The Book of Origins (hnewo tepyy) is a major ritual text of the Nuosu, a subgroup of the official Yi (Yizu) ethnic group of southwest China. The narrative, existing in both written and oral variants, is part of a living tradition, especially among priests (bimo) and folk singers, in the Liangshan Yi autonomous region in Sichuan province and nearby Yunnan province. The epic narrates the creation of the sky, earth, and living creatures through the frame of genealogies. After an age of scorching heat, life is re-seeded on earth and a descendant of the snow tribes of flora and fauna finds a bride. Many generations later this union results in the marriage between an earthling and the Sky God’s daughter. The tropes of genealogy and migration intertwine in the storyworld as clans descended from the couple seek out an “ideal place” to settle and prosper in the local environment in a pattern that resonates with other epics from the southwest and the Southeast Asian Massif.

Background. To evaluate the diagnostic accuracy of radiologists with a wide range of experience and training in emergency neuroradiology and other specialty hospitals, as well as the level of inter-experts’ agreement regarding CT signs of ischemic stroke.Material and methods. Our study included a retrospective cohort of 100 patients who underwent NCCT, CT angiography (mCTA) and CT perfusion in St. Petersburg clinical hospital. Fifty patients had confirmed middle cerebral artery ischemic stroke. The study also randomly included fifty patients in whom this diagnosis was excluded, including on the basis of dynamic follow-up as part of further clinical evaluation and follow-up CT scan of the brain. All 100 CT were reviewed by 21 radiologists who independently assessed each study for CT evidence of ischemic stroke. Statistical analysis included the Kappa-Fleiss coefficient ( ) calculation of agreement for each sign of ischemic stroke, specificity, sensitivity, and accuracy of detection of these changes.Results. The staff radiologist’s mean experience in emergency neuroradiology affects both diagnostic performance and consistency for detection of most CT features of ischemic stroke. At the same time, experience does not affect the diagnostic efficiency of radiologists with no experience in stroke assessment. The most highly specific and reproducible sign of ischemic stroke was the hyperdense middle cerebral artery sign, and the most ambiguous diagnostic sign was the gyral effacement. At the same time, all radiologists, regardless of length of service record and experience in emergency neuroradiology, are prone to over-diagnosis.Conclusion. Further search for tools and solutions is needed to level out interexpert variability regarding assessment of ischemic CT signs, since this problem has high clinical importance.

ФОРМУВАННЯ ОСОБИСТОСТІ МАЙБУТНЬОГО ЛІКАРЯ ЯК “ЛЮДИНИ КУЛЬТУРИ”
Authors: Ісаєва Оксана , Шайнер Ганна 
Published: June 2023

Сучасний період характеризує “людину культури” як рушійну силу, що визначає взаємовідносини, безпеку, благополуччя, виживання й розвиток особистості і суспільства загалом.
“Людина культури” розглядається як особистість діалогічна, оскільки у нинішніх умовах взаємини особистості з навколишніми і світом можуть бути успішними, якщо ґрунтуються на основі діалогу. Також діалогічна функція проявляється у здатності до комунікації, відкритості для творчої взаємодії та спільної кооперації. Власне ідея розвиватися, знаходити та оновлювати знання і практичні навички, системно мислити й породжувати нові ідеї, проявляти ініціативу та керувати емоціями, оцінювати ризики клінічної ситуації чи обґрунтовувати тактику лікування або власну позицію лише вступаючи у стосунки з колегами. Крім того, існує взаємозв’язок процесів розвитку емпатії і самореалізації особистості, що підводить до самовдосконалення на основі звернення до культури взаємовідносин, поваги до особистості та її прав; розвитку прагнення до самопізнання, самовдосконалення; формування позитивної “Я-концепції”; досвіду міжособистісної взаємодії; здатності до соціальної творчості, цивільної відповідальності.

For some companies, investment activity is an important element of the company's operations and the assessment of the company's performance may be largely, or entirely dependent on the results reported in this section. The purpose of the study was to determine and analyze the effect of investment opportunity sets (IOS) and Corporate Governance mechanisms on the value of property companies listed on the Indonesian stock exchange for the 2018-2020 period. This study used 24 property sector companies for the period 2018 and 2020. The results showed that the Investment Opportunity Set (IOS) had no effect on the value of the company. This is evidenced by a significance value of .032 and a calculated t value of 1.001. Meanwhile, the significance level is smaller than the established significance level of 0.319 0.05. Therefore, the second hypothesis is not accepted because there is no positive effect of the Investment Opportunity Set on the value of the company. The Corporate Governance mechanism has no effect on the value of the company. This is evidenced by a significance value of 0.012 and a calculated t value of 0.712. Meanwhile, the significance level is smaller than the established significance level of 0.478 0.05. Therefore, the second hypothesis is not accepted because there is no potitive influence of institutional ownership on the value of the company.
