У статті розглянуто тенденції виробництва натуральних смакоароматичних добавок гастрономічного напряму. Обґрунтовано доцільність використання сироваткових білків у смакоаро- матичних добавках. Метою статті є математичне моделювання процесу гідролізу сироваткових біл- ків за критерієм максимального виходу вільних амінокислот у разі використання ферментного каталі- затора. В експериментальних дослідженнях використовували комерційний концентрат сироваткових білків (КСБ-УФ-80) і лужну бактеріальну протеазу «Протолад». Оптимізацію параметрів фермента- тивного гідролізу проводили методом поверхонь відгуку, із застосуванням центрального композицій- ного рототабельного плану. Процес гідролізу сироваткових білків та отримання низькомолекулярних пептидів і амінокислот представлений у вигляді параметричної схеми. Визначено значущі техноло- гічні параметри процесу ферментативного гідролізу сироваткових білків: концентрація ферментного препарату (F, %) та субстрату (S, %), рН середовища (pH), температура (t, °С) і тривалість процесу (τ, хв) гідролізу. Оптимізацію процесу проводили за вихідним параметром моделі – вміст азоту амінних груп (NAG, мг / 100 г). По результатам проведених експериментів і математичної обробки отрима- них даних у вигляді рівнянь регресії було одержано модель процесу гідролізу сироваткових білків під дією ферментних препаратів. Регресійний аналіз даних показав всі вибрані фактори та їх взаємодії є значущими, рівень достовірності перевищує 95%. В результаті поетапного аналізу розробленої мате- матичної моделі оптимізовано процес гідролізу сироваткових білків ферментним препаратом «Про- толад». Встановлено, що найглибший ступень гідролізу відбувається за таких технологічних параме- трів: концентрація ферменту 4±0,01% і субстрату 18±0,5%, рН 7,7±0,1 і температура середовища 57±2°С, тривалість процесу 75 хв.

Polski przekład "Ars et praxis musica" Zygmunta Lauksmina z 1798 roku i problemy nauczania śpiewu chorałowego na ziemiach polskich w XVII i XVIII wieku
Authors: Grabiec Dominika
Published: May 2021

W bibliotece oo. Cystersów w Szczyrzycu, pod sygnaturą S.II.8/2, przechowywany jest rękopiśmienny egzemplarz nieznanego dotąd, polskojęzycznego podręcznika do nauki śpiewu chorałowego, sporządzony w 1798 r. w Limanowej i zatytułowany Nauka y praktyka muzyczna do używania uczącey się młodzi w Kollegiach Societatis Jesu za pozwoleniem starszych przełożona w Wilnie. Tekst ten zidentyfikowany został przez autorkę artykułu jako przekład traktatu Ars et praxis musica jezuity Zygmunta Lauksmina, wydanego w Wilnie w 1667 r. i dwukrotnie wznawianego w 1669 oraz 1693 roku. Recepcja wileńskiego podręcznika nie była do tej pory badana, a z trzech wydań zachowało się do dziś zaledwie kilka egzemplarzy. Odkrycie polskiego tłumaczenia sporządzonego w ostatnich latach XVIII w., a więc po ponad stu latach od ukazania się ostatniego wydania druku, w nowym świetle przedstawia zarówno dzieje wileńskiego podręcznika i jego oddziaływania, wykraczającego poza środowisko jezuickie i epokę baroku, jak również problemy nauczania śpiewu chorałowego u progu XIX wieku. Traktat Lauksmina był przeznaczony dla uczniów i studentów i miał być pomocą w praktycznym opanowaniu umiejętności śpiewu chorałowego, dlatego nie zawierał rozważań teoretycznych i ograniczał się jedynie do najbardziej podstawowych wiadomości oraz praktycznych wskazówek metodycznych. Tłumaczenie traktatu na język polski sporządzone w odmiennych już realiach historycznych, jest jednym ze stosunkowo niewielu zachowanych przykładów kształtowania się i ewoluowania polskiej terminologii muzycznej w XVIII wieku. Jest ono pośrednio także świadectwem ówczesnego stanu szkolnictwa muzycznego i braku nowoczesnych podręczników, który skłaniał do korzystania z materiałów dydaktycznych publikowanych jeszcze w poprzedniej epoce i przystosowywania ich do bieżących potrzeb lokalnych.

Aim. To study new collection corn accessions by vegetation period classes and its components to build up a trait collection.
Results and Discussions. The experiments were conducted in the eastern left-bank forest-steppe of Ukraine in the scientific crop rotation fields of the Plant Production Institute named after VYa Yuriev of NAAS in 2016-2019 Field surveys and laboratory analyses were carried out using methodological approaches to studying collection corn accessions. The article presents the results on building up a trait collection of corn, which includes 111 collection accessions of new domestic self-pollinated corn lines, diverse in their genetics, identified as carriers of a set of valuable economic and biological traits on the basis of previous studies. The pedigrees of the lines included seven synthetic populations from Australia and one synthetic population from the USA, three varieties from China, two varieties from Ukraine, two varieties from Syria, four lines from Ukraine, seven lines from the USA; three hybrids from Thailand, one hybrid from France, one hybrid from Serbia, and one hybrid from Egypt. Due to multi-year studies of corn collection accessions, sources of valuable economic traits with high levels of their expression were identified. The sources are of interest for breeding to create corn hybrids.
Conclusions. We grouped the lines was selected lines that are suitable for breeding: 24 lines with early emergence of seedlings (11-12 days), 29 lines with early anthesis (49–53 days), 64 lines with a minimum gap in anthesis (1-4 days), 14 lines with rapid water yielding belonging to various ripeness groups. We singled out cold-tolerant lines derived from a foreign (Egypt) hybrid (UKhK 653, UKhK 654, UKhK 655), from foreign (the USA, Australia) synthetics (UKhK 530, UKhK 692, UKhK 698). We also distinguished lines with increased productivity (86-116 g of grain per plant) and 1000-kernel weight (over 328 g): mid-early flint lines UKhK 724 and UKhK 727 derived from original French forms; nine mid-ripening lines originating from original Ukrainian (UKhK 612), American (UKhK 617, UKhK 618, UKhK 619), French (UKhK 725) and Egyptian (UKhK 653, UKhK 654, UKhK 655) forms; and one line from Thailand (UKhK 718), in which the vegetation period structure index ranged 0.8 to 1.0. We found sources of drought resistance: UKhK 719, UKhK 723, UKhK 724, and UKHK 726. Sources of good water yielding from grain are mid-early lines UKhK 690, UKhK 721, UKhK 730; mid-ripening lines UKhK 623, UKhK 631, UKhK 665, UKhK 672, UKhK 706 UKhK 715, UKhK 726; and mid-late lines UKhK 648, UKhK 652, UKhK 672, UKhK 720.

Aim. To evaluate drought- and heat- resistance of garden plum (Prunus domestica L.) accessions and forms in the Central Forest-Steppe of Ukraine
Results and Discussion. The study was carried out at L.P. Symyrenko Experimental Station of Pomology of the Institute of Horticulture of NAAS in 2018-2019. Fourteen accessions and 9 early-, mid- or late-ripening elite forms were studied. Recently, the climatic conditions in Ukraine have been characterized by an increase in the average annual temperature and unstable precipitation; there have often been periods without any precipitation. All these changes negatively affect the growth and development of plants. Analyzing the water-physical properties of different plum varieties, we measured the water content of leaf tissues. Most varieties had moderate water content ranging 55% (President) to 64.9% (Renklod Karbysheva). Record, Bluefri, Nenka, Oda and elite forms 7794, 12516, and 605 stood out, because the water content in their leaf tissues exceeded 60%. Investigation of the water balance in plum leaves revealed significant differences between varieties and hybrids. The water loss intensity varied. It was the lowest at all three exposures of leaves of forms 8087 and 9996 and variety Nenka (3.72-4.86, 9.53-11.06, and 14.90-15.61%, respectively). A high ability to retain water was also intrinsic to varieties Yantarnaya Mlievskaya (6.39%, 11.33%, 15.66%, Oda (7.21%, 12.84%, 18.48%), Dobra (7.73%, 13.66%, 19.58%), and Tophit (8.07%, 13.57%, 18.45%). The greatest loss of water of 19.21% and 20.56% after 2 hours was recorded in form 7794 and varietys Renklod Karbysheva.
Conclusions. The studied plum varieties and forms have been categorized according to water-physical indicators and drought resistance into the following groups: highly resistant (Nenka, 8087, 9996); resistant (Oda, Yantarnaya Mlievskaya, Dobra, Tophit); medium resistant (Herman, Stanley, Record, Blufri, 9605, 7756, 8124, 8143); lowly resistant (Zamanchyva, 8110). Renklod Karbysheva and elite form 7794 were the least resistant. The highest heat resistance was recorded for varieties Nenka, Oda, Stenley, Record and elite forms 12516, 8124, and 7794, in which the damage to leaves was 10-15%. The lowest heat resistance was seen in variety President and elite form 8143, in which the damage to leaves was 75%. In the other accessions and forms, this parameter ranged within 20-50% of the total leaf area, corresponding to medium heat resistance.

In this paper we present some basic problems of the metric fixed point theory (existence, uniqueness, settheoretic aspects (Bessaga, Janos, Rus, ...), order-theoretic aspects (Ekeland, Bronsted, Caristi, Kirk, Jachymski, ...), convergence of the succesive approximations, data dependence (general estimation, Ulam problem, dependence on the parameters, ...), well-posedness of the fixed point problem, limit shadowing property, stability, Gronwall lemmas, comparison lemmas, retractibility, ...). Following [I. A. Rus, The theory of a metrical fixed point theorem: theoretical and applicative relevances, Fixed Point Theory, 9 (2008), No. 2, 541–559] we define the relevance of a metrical fixed point theorem by the impact of the theorem on these basic problems. Some case studies are presented.

W. Burnside has proved that if a Sylow p–subgroup P of a finite group G is abelian and NG(P) = CG(P), then P has a normal complement, that is G is p–nilpotent. This result has been extended by A. Ballester-Bolinches and R. Esteban-Romero that have shown that if a Sylow p–subgroup P of a finite group G is modular and NG(P) = P CG(P), then G is p–nilpotent. In this paper we generalize the latter result to infinite groups. We show that a hyperfinite group G with a Sylow p–subgroup S that is modular and pronormal is p–nilpotent if and only if NG(S) is p-nilpotent.

Children are gifts and entrusted from God who are given talents and dignity as a whole creature. During their lifetime, children sometimes face legal problems such as narcotics abuse. This becomes complicated while the child has been married and being a subject against the law. The determination the age limit for children is still a debate because sev-eral laws and regulations provide different figures. This is, indeed, a crucial matter because it will affect legal conse-quence to the children, especially for those who deal with narcotics crime. Based on this point of departure, the authors examine Sampit District Court Decision Number: 03/Pid.SusAnak/2015/PN.Spt regarding narcotics abuse by a married child.

It has been observed that the level of science process skills and students' scientific attitudes, to seome extent, has not been formed, so the learning activity process has been running in slow motion. This study aims to examine the impact of project based learning (PjBL model) on the improvement of students‘ science process skills (KPS) and scientific attitudes, especially on plant tissue lesson. A pretest-posttest research design was applied to two classes of 8th grade students of SMPN 9 Palangka Raya, namely class VIIIA as the treated group, and while VIIIb as the control class using conventional learning models. The instruments used were lesson plans, science process skills observation sheets, scientific attitude questionnaires, and a number of test questions for testing. The results show that PjBL can improve science process skills with an N-gain of 0.70 in treated group, which is classified as high category, and N-gain of 0.48 in the control class which is in the moderate category. The PjBL implementation does not improve scientific attitudes because the N-gain value is 0.58 in the experimental class, quite similar to 0.32 point in the control class; both fall on moderate category.

Basic Instructional Speaking materials of English for Business Management plays important role in teaching learning process for Economic College in order that the education goal as stipulated in National Framework Curriculum (KKNI) could be achieved. The ability to use English in oral communication is the communicative goal. In fact, there have been many Higher Educations such as Economic College does not provide reliable instructional materials which are based on students‘ needs and industrial needs. Even the materials are not relevant to the students‘ Department. However, since there has no many ESP books and researches done due to this issue, this research was eventually carried out and the final product is to grand a basic instructional material of ESP for Economic Students. The data analyses were through interview and questionnaires to the first grade students of Sekolah Tinggi Ilmu Ekonomi Sampit. The results indicated the students are considered as basic learners of English who need appropriate materials as per their level ability. Therefore, instructional materials for Business English especially for basic learners who want to speak English for Business needs are hardly needed in STIE Sampit.

In the article, the main source of law of the Amir Temur state, the issues of punishment policy, the concept of the principles of social justice in the punishment, its importance in the "Temur regimes"are discussed. Social justice isn’t possible if only some voices are heard. Unfortunately, that’s often what happens and the voices of the marginalized and vulnerable are silenced. Even when society tries to address problems, solutions won’t work if those most affected can’t participate in the process. Participation must be encouraged and rewarded so that everyone – especially those who haven’t had a chance before – can speak.

Smart Principles and Smart Principals: Smart Mechanism to Enhance Street-Level Accountability
Authors: Yeo Jungwon , Jeon So Hee
Published: May 2021

This article presents a novel theoretical approach that aims to enhance the accountability of street-level bureaucrats. The authors conceptualize changes and reforms in and around the public sector as a smart mechanism that is composed of two key dimensions; a) smart principles (i.e., institutions and technological tools that support citizen participation), and b) smart principals (i.e., citizens who adopt those smart principles in monitoring and evaluating street-level agents’ behaviors). Then the authors suggest a theoretical framework that explains how applying the smart mechanism can limit deviant behaviors of street-level bureaucrats and contribute to enhancing street-level accountability.

Authors: H. V. Harish , K. Manjunath , T. Rangaswamy
Published: May 2021

In order to improve thermo-hydraulic performance of laminar flow various techniques has been used among which a plain tube with twisted tape insert is widely used. The main objective is to numerically study flow field in order to enhance heat transfer, through a circular pipe built in with/without Dimples on twisted strip. Effect of plain and dimple strip on thermo hydraulic performance discussed. The analysis results for laminar range of 800<Re<2000 is obtained with twist ratio of the strip is 3.0. Analysis is carried for full length tape with constant heat flux. The simulation results of Nusselt number versus Reynolds number of the plain, plain twisted tape and Dimple twisted tape with the experimental data give variation of 2.5, 5.75 and 9.5%. The friction factor of Dimple twisted tape tube is 6 to 13 times that of the plain tube. The thermal performance factor of the Dimple twisted tape and plain twisted tape tube is 4 to 15% and 3 to 12 % respectively higher than that of plain tube. Due to increase in thermal performance factor of induced strip with dimples there is an intensification of heat transfer obtained through circular duct with dimple twisted tape insert than that of plain twisted tape and plain pipe. The use of a twisted tube compounded with dimples is feasible in terms of energy saving at lower Reynolds numbers. Present study is applicable for design of compact heat exchanger in order to optimize energy consumption.
Effect of Internal Diameter and Working Fluids on Thermal Performance of a Vertical Closed-Loop Oscillating Heat Pipe with Double Heat Sources
Authors: Krisangsri Poomin , Hudakorn Teerasak , Sritrakul Noppong
Published: May 2021

This research investigates the effects of internal diameter and working fluids on the thermal performance of a vertical closed-loop oscillating heat pipe with double heat sources (VCLOHP w/DHS). The closed-loop oscillating heat pipe (CLOHP) tested was made of a copper capillary tube with various inner diameters and working fluids. Two evaporator sections in the outer end of CLOHP were heated by a Ni-Cr alloy resistance wire heater. The heat was removed from the condenser section in the middle of CLOHP by forced convection heat transfer of ambient air blowing the section. The results showed that, for the inner diameters of 1.5 and 2.0 mm, the thermal resistance decreased when the inner diameter and the latent heat of evaporation increased.

Adesão à Organização para a Cooperação e Desenvolvimento Econômico, exportações e investimentos: uma análise exploratória
Authors: Reis José Guilherme , Soares André
Published: May 2021

Desde 2017, o governo brasileiro estabeleceu como objetivo a adesão à Organização para a Cooperação e Desenvolvimento Econômico (OCDE), uma instituição formada por 36 países membros que buscam discutir, difundir e alinhar melhores práticas em termos de governança e políticas públicas. A OCDE tem se expandido em anos recentes, tendo incluído dez países desde a década de 1990. É natural que haja interesse em conhecer os possíveis impactos dessa adesão sobre o desempenho econômico dos países. A literatura recente sobre cadeias globais de valor (CGVs) sugere que aspectos extratarifários que têm sido crescentemente incorporados a acordos comerciais tem beneficiado o crescimento dessas cadeias de valor. Neste artigo, utilizando técnicas econométricas diversas, fazemos uma análise exploratória do desempenho das exportações e dos investimentos estrangeiros diretos desses países, em comparação com o desempenho dos países que não aderiram à instituição. Encontramos efeitos significativos, ainda que modestos, sobre ambas as variáveis. Tendo em vista o grau de agregação, preferimos interpretar esses resultados como correlação, e não causalidade. De todo modo, o impacto limitado sugere que ganhos mais substanciais em termos de crescimento e exportações para uma economia como a brasileira requerem medidas de aprofundamento da integração em diversas dimensões, em particular na área de bens e serviços.
A Experiência Latino-Americana na OCDE: referências para o Brasil
Authors: Neves Leonardo Paz
Published: May 2021

Este artigo pretende buscar, na experiência dos países latino-americanos membros da Organização para a Cooperação e o Desenvolvimento Econômico (OCDE), a identificação de benefícios concretos e obstáculos vividos na sua relação com a organização. Para tal, é feita uma breve contextualização do processo de filiação de México, Chile, Colômbia e Costa Rica à OCDE. Além disso, realiza-se uma breve análise de alguns importantes indicadores presentes nas narrativas positivas e negativas à entrada de países em desenvolvimento na OCDE, levando em conta México, Chile e Brasil. O texto conclui que, no caso do Brasil, a decisão de ingressar na OCDE deve fazer parte de um debate mais amplo na sociedade – um debate que resultará em decisões estruturais no campo econômico e das relações exteriores.
