Для питьевого водоснабжения часто используются подземные источники воды с повышенным содержанием солей жесткости. Для достижения питьевого качества воды требуется снижение ее жесткости. Известные методы умягчения приводят к образованию значительного количества жидких и твердых отходов – минерализованных сточных вод или шламов, не подлежащих утилизации. Реагентное умягчение воды в осветлителях используется достаточно редко из-за трудности приготовления реагентов, поддержания необходимой и постоянной температуры воды, сложности установок и их обслуживания. В 1990-х годах разработана технология реагентного умягчения в интенсифицированных реакторах (вихревых и во взвешенном слое), получившая довольно широкое применение в питьевом водоснабжении. Такие аппараты достаточно активно используются в Европе и США. В настоящее время АО «Научно-производственная компания «Медиана-Фильтр» проводит работы по созданию и исследованию реакторов данного типа. Они имеют высокую удельную производительность – 50–100 м3/(м2‧ч), и их обслуживание существенно проще по сравнению с осветлителями. Производительность таких установок достигает тысяч кубометров в час. Главное их преимущество заключается в отсутствии жидких сбросов и получении отхода в твердом виде, который может быть утилизирован, при этом выход чистой воды практически составляет 100%.
Underground water sources with a high content of hardness salts are often used for drinking water supply. To achieve drinking water quality reducing its hardness is required. Known methods of softening result in the formation of a significant amount of liquid and solid wastes, i. e. mineralized wastewater or sludge that cannot be disposed of. Chemical water softening in clarifiers is used quite rarely owing to the difficulty of preparing chemicals, maintaining the constant required water temperature, and the complexity and maintenance of the equipment. In the 1990s, the technology of chemical softening in intensified reactors (vortex and blanket) was developed that gained widespread use in drinking water supply. Such units are quite frequently used in Europe and USA. At present Mediana-Filter Research and Production Company JSC is taking on the task of designing and testing reactors of this type. They have a high specific output of 50–100 m3/(m2‧h), and their maintenance is much easier compared to clarifiers. The capacity of such plants reaches thousands of cubic meters per hour. Their main advantage is the elimination of liquid discharges and generation of solid wastes that can subject to utilization, while the yield of clean water is about 100%.

Soyogik (Saurauia bracteosa DC) merupakan tanaman obat yang berasal dari Minahasa Tenggara, Provinsi Sulawesi Utara. Penelitian ini bertujuan untuk menentukan potensi aktivitas antioksidan ekstrak dan fraksi pelarut dari daun soyogik. Ekstraksi dilakukan dengan maserasi menggunakan metanol dan fraksinasi dengan n-heksana dan etil asetat. Kandungan total fenolik ekstrak dan fraksi diukur menggunakan uji Folin-Ciocalteu sedangkan aktivitas antioksidan dievaluasi dengan penghambatan oksidasi asam linoleat dengan metode Ferric Thiocyanate (FTC) dan penghambatan malonaldehid (MDA) dengan metode Thiobarbituric Acid Reactive Substance (TBARS). Hasil penelitian menunjukkan bahwa kandungan fenolik yang dinyatakan dalam ekuivalen asam galat dari ekstrak dan fraksi berkisar antara 50,83-99,67 g/mL. Fraksi etil asetat memiliki kandungan fenolik yang lebih tinggi dibandingkan fraksi heksana dan ekstrak metanol. Hasil penelitian ini juga menunjukkan bahwa fraksi etil asetat, n-heksana, dan α-tokoferol memiliki penghambatan peroksida masing-masing sebesar 50,21, 44,26, dan 46,96% dan penghambatan malonaldehid masing-masing 91,03, 88,81, dan 89,48%. Kemampuan hambat peroksida dan malonaldehid menunjukkan bahwa fraksi etil asetat memiliki aktivitas antioksidan yang lebih tinggi dibandingkan fraksi n-heksana dan a-tokoferol sebagai kontrol positif.ABSTRACT Soyogik (Saurauia bracteosa DC) is a medicinal plant originating from Southeast Minahasa, North Sulawesi Province. The objective of study was to determine the potential antioxidant activity of the extract and the solvent fraction of soyogik leaves. Extraction was carried out by maceration using methanol and fractionation with n-hexane and ethyl acetate. The total phenolic contents of extract and fractions were measured using a Folin-Ciocalteu assay while the antioxidant activities was evaluated by the inhibition of linoleic acid oxidation with the Ferric Thiocyanate (FTC) and measuring the malonaldehyde (MDA) inhibition with the Thiobarbituric Acid Reactive Substance (TBARS) methods. The results showed that phenolic content expressed in gallat acid equivalent of extract and fractions ranged from 50.83-99.67 µg/mL. The ethyl acetate fraction has higher phenolic content than hexane fraction and methanol extract. The results showed also that the ethyl acetate, n-hexane fractions and a-tocopherol had peroxide inhibition were 50.21, 44.26, and 46.96%, respectively and the inhibition of malonaldehyde were 91.03, 88.81, and 89.48% respectively. The inhibitory ability of peroxides and malonaldehyde showed that the ethyl acetate fraction had higher antioxidant activity than the n-hexane and a-tocopherol fractions as positive controls.
Structures and stability of GaN/Ga2O3 interfaces: a first-principles study

Published: March 2022

Abstract
The structures and stability of the interface between GaN and Ga2O3 are theoretically investigated on the basis of first-principles calculations. We determine the stable structures of the interfaces with α-phase and β-phase Ga2O3 (GaN/α-Ga2O3 and GaN/β-Ga2O3 interfaces, respectively) using absolute interface energies. The calculated absolute interface energies for various atomic configurations demonstrate that the stable structure strongly depends on the oxygen chemical potential. For the GaN/α-Ga2O3 interface, the structures with Ga vacancy are stabilized over the wide range of oxygen chemical potential. On the other hand, the interface with Ga–O bonds are favorable over the wide range of oxygen chemical potential for the GaN/β-Ga2O3 interface. Furthermore, we clarify the interface structures of GaN/Ga2O3 by considering the experimental thermal oxidation conditions. The calculated results provide firm theoretical frameworks to understand the formation mechanism of oxide films by thermal oxidation of GaN substrate.

Published: March 2022

This paper aims to investigate the Mutual Fund industry's performance in Bangladesh, considering the close-end mutual funds of 32 listed funds in the Dhaka Stock Exchange, Bangladesh. The study employed unbalanced panel data analysis throughout 2014 to 2019. By using an error-corrected panel data regression model with an attempt to investigate the performance of mutual funds considering several fundamental factors such as Return on Assets, Earning per unit, Fund Size, Fund Age, Dividend payout ratio, Net Asset Growth and Management Fees, etc. After correcting autoregressive disturbance, the RE GLS regression model is selected to describe this panel data analysis. It demonstrates a significant positive connection between earning per unit and return on assets. The study identifies a significant negative relationship with fund age and asset growth in response to the change of return on assets. It also concludes there is no significant predictive power among the fund size, dividend payout ratio, management fees with return on assets while defining mutual fund performance. The study fills the gap by investigating the significant relationship of these following variables with the fundamental performance indicator. Findings of the empirical analysis suggest that the investors should pay close attention to earnings, fund age and assets growth while selecting mutual funds for investment. It is noticed that the company generally tends to pay lower dividend when the performance and profitability starts decrease. Policy makers should also pay attention to defining the downward characteristics of asset growth and dividend payout compared to the basic profitability ratios.

Late sign language exposure does not modulate the relation between spatial language and spatial memory in deaf children and adults
Authors: Karadöller Dilay Z. , Sümer Beyza , Ünal Ercenur , Özyürek Aslı 
Published: March 2022

AbstractPrior work with hearing children acquiring a spoken language as their first language shows that spatial language and cognition are related systems and spatial language use predicts spatial memory. Here, we further investigate the extent of this relationship in signing deaf children and adults and ask if late sign language exposure, as well as the frequency and the type of spatial language use that might be affected by late exposure, modulate subsequent memory for spatial relations. To do so, we compared spatial language and memory of 8-year-old late-signing children (after 2 years of exposure to a sign language at the school for the deaf) and late-signing adults to their native-signing counterparts. We elicited picture descriptions of Left-Right relations in Turkish Sign Language (Türk İşaret Dili) and measured the subsequent recognition memory accuracy of the described pictures. Results showed that late-signing adults and children were similar to their native-signing counterparts in how often they encoded the spatial relation. However, late-signing adults but not children differed from their native-signing counterparts in the type of spatial language they used. However, neither late sign language exposure nor the frequency and type of spatial language use modulated spatial memory accuracy. Therefore, even though late language exposure seems to influence the type of spatial language use, this does not predict subsequent memory for spatial relations. We discuss the implications of these findings based on the theories concerning the correspondence between spatial language and cognition as related or rather independent systems.
