Kinetic models of quality parameters of spreadable processed Gouda cheese during storage
Dorota Weiss,Jerzy Stangierski,Hanna Maria Baranowska,Ryszard Rezler 한국식품과학회 2018 Food Science and Biotechnology Vol.27 No.5
The aim of the study was to prepare mathematical models based on the Arrhenius equation as predictive tools for the assessment of changes in quality parameters during the storage of spreadable Gouda cheese at temperatures of 8, 20 and 30 C. The activation energy value and the chemical reaction rate constant enabled the construction of kinetic models, which helped to estimate the direction and rate of changes. Moreover, the activation energy (Ea) of the quality parameters was used to determine the sequence of their vulnerability during storage. The value of activation energy corresponding to temperature changes resulted in the following order of susceptibility of the quality parameters: DC[DE & water activity[texture parameters[pH[colour[sensory parameters[rheological parameters. The research showed limited applicability of the mathematical models for estimation of quality parameters referring to spreadable processed Gouda cheese.
ON PARAHOLOMORPHICALLY PSEUDOSYMMETRIC PARA-KAHLERIAN MANIFOLDS
Dorota Luczyszyn,Zbigniew Olszak 대한수학회 2008 대한수학회지 Vol.45 No.4
We find necessary and sufficient conditions for a para-Kahlerian manifold to be paraholomorphically pseudosymmetric in terms of the paraholomorphic projective and Bochner curvatures. New examples of such spaces are proposed.

Zeolite properties improvement by chitosan modification—Sorption studies
Dorota Kołodynska,Paulina Hałas,Małgorzata Franus,Zbigniew Hubicki 한국공업화학회 2017 Journal of Industrial and Engineering Chemistry Vol.52 No.-
In the paper the potential of chitosan modified zeolite (NaP1CS) as a cheap adsorbent for methylene blue(MB) removal from aqueous solutions was determined. Fourier transform infrared spectroscopy analyses,nitrogen adsorption/desorption isotherms and scanning electron microscope were applied tocharacterize the adsorbent. Batch adsorption studies were carried out to examine effects of variousfactors such as pH, contact time, initial MB and Cu(II) concentrations, temperature influence on thesorption process. The impact of different ways of zeolites modification with chitosan on sorption capacityand the comparison of adsorption of unmodified zeolite andfly ash are presented. The effect of differentmetal ions such as Cu(II), Zn(II), Mn(II), Fe(III) and also that of foreign ions on the MB sorption were alsostudied. The pseudo-first order, pseudo-second order and intraparticle diffusion models werefitted tothe kinetic data. The bestfit was achieved with both the pseudo-second order and intraparticle diffusionmodels. The experimental equilibrium data were evaluated by the Langmuir, Freundlich, Temkin andDubinin-Radushkevich isotherm models. The calculated thermodynamic parameters indicated aspontaneous and endothermic sorption process. Desorption studies were carried out with differentdesorbing agents. HCl proved to be the most effective desorption agent for MB and Cu(II).

We prove, under some general assumptions, that a generator of any uniformly bounded Nemytskij operator, mapping a subset of space of functions of bounded variation in the sense of Wiener-Young into another space of this type, must be an affine function with respect to the second variable.
Multi-Sensor Personal Navigator : System Design and Calibration
Dorota A. Grejner-Brzezinska, Charles K. Toth, Yoonseok Jwa, Shahram Moafipoor, Jay Hyoun Kwon 서울시립대학교 도시과학연구원 2006 International journal of urban sciences (IJUS) Vol. No.
This paper presents the current design status and some preliminary calibration/performance analyses of the prototype of a multi-sensor personal navigator currently under development at The Ohio State University. The main purpose of this research project is to develop a theoretical foundation and algorithms which integrate the Global Positioning System (GPS), Micro-electro-mechanical inertial measurement unit (MEMS IMU), barometer and compass to provide seamless position information to support navigation and tracking of ground military and rescue personnel. The system is designed with an open-ended architecture, which would be able to incorporate additional navigation and imaging sensor data, extending the system’s operations to the indoor environments. The current target accuracy of the system is at 3-5 m CEP (circular error probable). In the current prototype implementation, the following sensors are integrated in the tightly coupled Extended Kalman Filter (EKF): GPS carrier phase and pseudorange data, Crossbow MEMS IMU400C, PTB220A barometer, and KVH Azimuth 1000 digital compass. This paper focuses on the design architecture of the integrated system and the preliminary performance analysis, with a special emphasis on the navigation during the loss of GPS signal. A brief description of the individual sensors and their calibration is presented, together with the navigation performance of the system of sensors. In addition, the system’s architecture designed to incorporate a simplified dynamic model of human locomotion is introduced. The system is trained during the GPS signal reception and is subsequently used to support navigation under no GPS signal. The stride parameters (step frequency and length), extracted from GPS data and the timed impact switches during the system calibration period, and the heading information from the compass and the IMU support the dead reckoning navigation, during the gaps in GPS signals. Some information included here is also presented in (Grejner-Brzezinska et al., 2006).
Status niekonotowanych fraz celownikowychwe współczesnej polszczyźnie a delimitacja jednostek języka
Dorota Kruk 한국슬라브어학회 2023 슬라브어연구 Vol.28 No.1
The author describes a certain type of non-obligatory dative phrases, interpreted as dativus ethicus, dativus possesivus, dativus commodi and dativus incommodi, cf. Ładny mi przyjaciel., Syn nam się rozchorował., Ugotowałam ojcu obiad. The analysis of dative phrases does not include the multifunctional Polish expression sobie. Most common usage of dative in the Polish language (as an obligatory valency slot ) is to refer to the real recipient or beneficiary of an action. It is also used as some sort of commentary, when one wants to show their commitment to the action and when one feels like a quasi-recipient of this action (as an non-obligatory valency slot). The author provides her own interpretation of the function of non-obligatory dative phrases in Contemporary Polish Language. The author also considers a number of problems with interpreting dative forms in sentences as non-obligatory phrases or as required arguments (immanent parts of language units). In the article, units of language are understood as separate entities (continuous or discontinuous) to which (in most cases) a single meaning is assigned. As regards valency slots, they are treated as immanent parts of expressions, unlike lexemes filling these slots in an utterance. The procedure of language-unit delimitation aims at identifying exactly those elements, the detachment of which would result in the unit losing its semantic properties.

The aqueous photosensitized degradation of butylparaben
Gryglik, Dorota,Lach, Marta,Miller, Jacek S. Korean Society of Photoscience 2009 Photochemical & photobiological sciences Vol.8 No.4
The photosensitized oxidation of butyl p-hydroxybenzoate (butylparaben, BP), the endocrine disrupting compound, in aqueous solution using rose bengal (RB) and aluminium phthalocyanine chloride tetrasulfonic acid (PC) as sensitizers was examined. A xenon lamp simulating solar radiation was used as a light source. The influence of pH of the reaction mixture, oxygen content, irradiation intensity and initial sensitizers and BP concentration on the reaction rate was studied. Based on the kinetic model, the rate constants of singlet oxygen quenching and reaction with BP as well as the rate constant of excited sensitizer quenching by BP were determined.

본 논문의 취지는 번역가가 양면의 가치를 지닌 텍스트를 번역할 때 접하게 되는 어려움을 유형별로 고찰하는 것이다. 본 논문은 이를 위해 폴란드 어로 번역된 『이상한 나라의 앨리스』네 편을 다루고 있다. 『이상한 나라의 앨리스』를 번역하는 것은 특별한 도전이다. 언어학적 풍부함, 복잡성, 예술적 가치라는 텍스트 자체의 특성에다, 어린이 보다는 성인들이 더 많이 감상하는 고전이라는 점 때문이다. 『앨리스』는 당초 어린이를 위해 쓰인 책이지만 독자층이 어린이 이상으로 확대되고 있다 (필립스, 1972: xxii). 오늘날 『앨리스』의 독자층은 어린이/ 성인 양쪽을 망라하고 있다. 따라서 『앨리스』를 특정 목표언어로 번역하려면 독특한 문제점에 봉착하게 된다. 번역상의 주된 어려움은 상상의 세계에서 펼쳐지는 대단한 모험이야기가 제공하는 유머와 흥미를 어린이의 눈높이에 맞춰 번역해야 하고, 동시에 혁신적인 언어의 구사, 언어에 대한 유희, 역설 또는 허무맹랑한 이야기를 가미하는 등 성인의 눈높이도 맞춰야 한다는 것이다. 본 논문은 폴란드의 번역가들이 루이스 캐럴의 소설에 나타나는 이 같은 번역상의 어려움을 얼마나 다른 시각으로 풀어낼지를 설명할 것이다. 또한 번역가가 취하는 특별한 번역 전략 뿐 아니라, 대상 독자 선택으로 인해 초래된 번역가의 (비)가시성에 대해서도 논증하고자 한다.
