HYDROXY ACIDS AND POLYOLS AS POTENTIAL EXTRACTANTS FOR IONMETRIC DETERMINATION OF BORON IN SOILS
Authors: Petruliak Ya. , Fershal M. , Galas M. 
Published: April 2022

Boron is an essential element for plants, animals, and humans. Its deficiency in plants may result in reduced growth rates, yield loss, and even death. At the same time, excess of boron is toxic for both plants and living organisms. Boron is important for steroid hormones production, vitamin D and minerals metabolism, formation of bone tissue, and affects estrogen and testosterone levels. The primary source of boron for humans and other living organisms is plant-origin food. The richest ones are fruits and nuts. High concentrations of boron are found in raisins (22 mg/kg), peanuts (17 mg/kg), peanut butter (14,5 mg/kg). In the agriculture the boron monitoring in soils and water irrigation is particularly important because this element is crucial for plant growth Boron deficiency has a drastic effect on fruit quality and yield, even when there are only mild or moderate foliar symptoms.
The main source of boron for plants is soil and water. Quantitative determination of boron in soil extracts can be performed using spectrophotometric, potentiometric, chromatographic, atomic absorption spectrophotometric, and inductively coupled plasma techniques. The most popular are inductively coupled plasma optical emission spectrometry (ICP-OES) and inductively coupled plasma mass spectrometry (ICP-MS). These methods are described in the appropriate standards PN-EN ISO 11885:2009 and PN-EN ISO 17294–1:2007.
Boric acid is known to form complexes through esterification reactions with hydroxy-group in molecules of amino- and carboxylic acids, carbohydrates, nucleotides and vitamins that can be used for boron extraction from soils. Partial esterification results in monoesters (1:1 complex) and complete esterification leads to the bicyclic diester (1:2 complex).
In present research the tetrafluoroborate selective sensor applicable for fluoroborate formation reaction monitoring was used as an analytical tool for the investigation of an impact of soil extraction procedure for boron analysis. The investigation of alternative soil boron extraction procedures using α-hydroxy acids (and other cis-diol containing compounds) and subsequent quantitative analysis of boron by kinetic-potentiometric monitoring of fluoroborate formation rate with use of previously developed [BF4]¯-selective electrode have been performed. The kinetics of complex destruction under fluoride containing acidified media by means of kinetic-potentiometric analysis has been investigated. The possible boron losses during its extraction from soils have been checked.

The catalytic system of 50% Cu3(PO4)2∙50% Ni3(PO4)2 based on Copper (II) and Nickel (II) orthophosphates was synthesized by the coprecipitation method according to the method developed at the Department of Physical and Colloid Chemistry of Uzhhorod National University. The synthesized system was investigated by the method of differential thermal analysis. The obtained results can be interpreted in favor of the formation of a new phase, which is formed due to the equiatomic interaction of the initial components. Thus, a number of thermal effects different from Cu3(PO4)2∙3H2O and Ni3(PO4)2∙8H2O are observed on the corresponding thermogram. The only endothermic effect at 117 ° C is not recorded on the thermograms of the starting components. In the case of a solid solution or a simple mixture of phases based on starting phosphates, this effect should be observed at intermediate temperatures in the range from 129°C to 268°C. Probably, the newly formed phase, by the number of moles of water of crystallization, differs from the original individual orthophosphates. Information about a more accurate number of molecules of chemically bound water in hydrated forms of the synthesized complex copper-nickel phosphate catalyst will allow to establish the results of additional studies by derivatographic or gravimetric analyzes, which were not performed in this work. After dehydration with a further increase in temperature, no endothermic effect for a complex catalytic system is observed. Instead, four exothermic effects are recorded at once: the first two - at 456ºС and 564ºС (both insignificant in area), and the next two at slightly higher temperatures - 658ºС and 777ºС (larger in area). The effects at 564ºC and 658ºC can be attributed to the crystallization of dehydrated Cu3(PO4)2. The exoeffect at 777°C corresponds to the formation of the structure of dehydrated orthophosphate Nickel Ni3(PO4)2. Thus, the obtained experimental data of differential thermal analysis confirm the effective modifying role of Ni2+ ions on the structure, phase formation and a number of physicochemical properties of copper (II) phosphate in the synthesis of a complex oxide catalyst. This made it possible to obtain a new cheap and active complex acid catalyst with improved catalytic properties of 50 % Cu3(PO4)2∙50 % Ni3(PO4)2, which can be used for the process of converting natural gas components into valuable products of the chemical industry.

Predicting students’ academic performance is very essential to produce high-quality students. The main goal is to continuously help students to increase their ability in the learning process and to help educators as well in improving their teaching skills. Therefore, this study was conducted to predict mathematics students’ performance using Artificial Neural Network (ANN). The secondary data from 382 mathematics students from UCI Machine Learning Repository Data Sets used to train the neural networks. The neural network model built using nntool. Two inputs are used which are the first and the second period grade while one target output is used which is the final grade. This study also aims to identify which training function is the best among three Feed-Forward Neural Networks known as Network1, Network2 and Network3. Three types of training functions have been selected in this study, which are Levenberg-Marquardt (TRAINLM), Gradient descent with momentum (TRAINGDM) and Gradient descent with adaptive learning rate (TRAINGDA). Each training function will be compared based on Performance value, correlation coefficient, gradient and epoch. MATLAB R2020a was used for data processing. The results show that the TRAINLM function is the most suitable function in predicting mathematics students’ performance because it has a higher correlation coefficient and a lower Performance value.

Even though people can make complaints through a computerized system, some places still use the manual system. The manual system is inconvenient for the complainant because they must visit the respective counter to channel the complaints. In addition, the form provided usually consists of long instructions for the complainant to read before channelling the complaint. This paper discusses the development of an e-Complaint System for UiTM Perlis colleges embedded with gamification. In this system, there are three gamification elements included, which are the progress bar, leaderboard, and Avatar selection for personalization. Two tests were conducted, which are functionality and usability testing through various platforms such as YouTube, 000webhost, and Google Form. There were 33 respondents for the usability testing consisting of students and staff of UiTM Perlis. While the functionality testing was conducted with UiTM Perlis lecturers who have experienced teaching IT subjects. From the responses obtained from the respondents through PPSUQ Survey, most of the respondents agreed that the developed system helped them in channelling complaints and updating the status of their complaints compared to the existing system. The system developed does include some gamification elements which can ease the users to use the e-complaint system in the future. Via this system, users were guided on how to lodge complaints via step-by-step process instead of reading long instructions which could lead them to confusion.
CLAUSAL ADJUNCTS OF ROMANCE LANGUAGES – A CORPUS-DRIVEN COMPARISON –
Authors: BODOC Alice 
Published: April 2022

Clausal Adjuncts of Romance Languages – a Corpus-Driven Comparison. Continuing the traditional comparative analysis of Romance languages, the present paper brings evidence for the fact that the syntactic configuration (the word order) of a Romance complex sentence (henceforth CS) with clausal adjuncts is the result of many competing forces. The analysis is based on an original media discourse corpus, collected from three Romance varieties (Romanian, Italian, and French), and the focus will be both on the word order of the temporal, causal, and concessive adjuncts (their occurrence in sentence-initial, in sentence-final position, sometimes even in sentence-middle position), and on the comparative analysis of the results. What I intend to prove is that the ordering of a CS in the three Romance languages is motivated by three types of factors: discourse pragmatics, semantics, and parsing.

REZUMAT. Adjuncții propoziționali din limbile romanice – o analiză de corpus din perspectivă comparativă. Continuând tradiția analizelor comparative dedicate limbilor romanice, lucrarea de față își propune să prezinte o serie de dovezi în favoarea ipotezei potrivit căreia configurația sintactică (ordinea constituenților) a structurilor sintactice complexe cu adjuncți din limbile romanice este rezultatul mai multor forțe concurente. Analiza are la bază un corpus original de texte aparținând discursului mediatic contemporan, colectat din trei varietăți romanice (limba română, limba italiană și limba franceză) și se concentrează, pe de o parte, asupra descrierii poziției adjuncților temporali, cauzali și concesivi (de la începutul, sfârșitul sau chiar din mijlocul structurii sintactice complexe), iar, pe de altă parte, asupra comparării rezultatelor obținute în cazul celor trei limbi investigate. Scopul unui astfel de demers este de a demonstra că topica acestor structuri este motivată, atât în limba română, cât și în celelalte două limbi-surori, de trei tipuri de factori: pragmatico-discursivi, semantici și morfosintactici.

Light and heavy ferritin chain expression in the liver and kidneys of Wistar rats: aging, sex differences, and impact of gonadectomy

Published: April 2022

Abstract
Ferritin is the main intracellular storage of iron. Animal studies show that female liver and kidney express more ferritin and accumulate more iron than male. However, no study so far has investigated sex and age differences in light (FtL) and heavy (FtH) ferritin chain expression. To address this, we relied on specific antibodies and immunochemical methods to analyse the expression of both ferritin chains in the liver and kidney of 3-month and 2-year-old male and female Wistar rats. To see how sex hormones may affect expression we also studied adult animals gonadectomised at the age of 10 weeks. FtL and FtH were more expressed in both organs of female rats, while gonadectomy increased the expression in males and decreased it in females, which suggests that it is stimulated by female and inhibited by male steroid hormones. Normal kidney ferritin distribution and change with aging warrant more attention in studies of (patho) physiological and toxicological processes.

Surgery of combined anal and rectal diseases requires an unconventional tactics and methods of treatment of these pathologies, which provide minimal impact on tissues, preventing postoperative complications. The aim of the study was to conduct a comparative evaluation of the effectiveness of new radiosurgical and electrosurgical technologies in the treatment of combined anal and rectal diseases by analyzing the clinical course of the postoperative period and the impact of these energy devices on the morphostructure of operated tissues. The results of treatment of 747 patients with combined anal and rectal diseases divided into four research groups and control group have been analyzed. In the first research group 169 (22,6%) patients with electrosurgery device “ERBE ICC 200” have been operated on in the second research group – 114 (15,3%) patients with electrosurgery device "EFA", in the third research group – 107 (14,3%) patients – with electrosurgery device "KLS Martin" and in the fourth research group – 245 (32,8%) patients with radiosurgery device "Surgitron". The control group consisted of 112 (14,9%) patients operated with a surgical scalpel. After surgery 30 patients from each study group underwent morphological investigation of rectal and anal tissues for measurement of the thickness of thermal impacts on them, which was performed using an eyepiece-micrometer scale. Due to the minimal and insignificant impact on the tissues during application of electrosurgery devices “KLS Martin”, “EFA” and “ERBE ICC 200”, as well as radiosurgery device "Surgitron", there were detected neither scar anal strictures in any of the four study groups, nor scarring deformities of the pararectal areas, which contributed to the cosmetic nature of the combined operations and caused rapid rehabilitation of patients in the study groups. In the control group in 2 (2%) patients the formation of scar anal stricture was diagnosed, which required conservative (1 patient) and operative (1 patient) measures to eliminate them. Using modern radiosurgery and electrosurgery technologies for treatment of combined anal and rectal diseases reduces the operation duration, volume of bleeding and intensity of the postoperative pain. Application of these above technologies prevents the occurance of anal strictures and scar pararectal deformations.
