Soil water regime in the fields of corn fields under different tillage practices
Authors: Петренко С.В.
Published: June 2023

The results of ecological tests of corn hybrids of Ukrainian selection under different methods of main tillage (moldboard ploughing to a depth of 25‒27 cm, minimal tillage (disc and sweep), to a depth of 14‒16 cm, no-till) are presented. The research was conducted in the experimental field of the Department of Arable farming of the Institute of Agriculture of the North-East of Ukraine on chernozem typical silt loam on loess (content of humus by Tyurin 4,1‒4,7 % рНKCl 6,0, рНH2O 7,9). 2018‒2020 years of research were significantly warmer than the average long-term indexes during May-September. It was found that the weather conditions of the growing season of corn on average for 2018‒2019 were characterized as very arid (hydrothermal coefficient HTC = 0.57) with ranging from very arid in 2018 and 2019 (HTC = 0.45‒0.46) to arid in 2020 (HTC = 0.80). It was determined that the value of total water consumption did not depend on the methods of tillage and, under other equal factors, determined by the total precipitation and ranged from 245.4–252.2 mm with precipitation of 110.4 mm to 319.1–321, 4 mm at 230 mm.

It is established that the influence of precipitation in the structure of total water consumption depends on their amounts and if it were about 44.2‒45.0 % at precipitation of 110.4 mm, with 230.0 mm would be 71.6–73.1 %. On that account, a portion of the total water consumption from 0‒50 cm soil layer did not depend on precipitation and in the average was 0.77–0.79.

In 2018‒2020, corn hybrids of Ukrainian selection with N100P45K45-ferilizers formed quite high yields (9.40–7.78 t/ha) with a significant dependence on FAO. The yield of hybrid Donor (FAO 310) did not depend on tillage, while hybrids Zoryany (FAO 190) and Leleka (FAO 260) gave the highest yields on ploughing plots without significant responce to other methods of basic tillage. The Donor hybrid formed a statistically equal yield on all variants in all years of research.

Published: June 2023

Judges as court apparatus, play a pivotal role in improving organizational performance and enhancing public trust. They are the sole actor who determines the quality of court decisions. However, the cases in the four courts, namely general, religious, state administrative and military courts seemed to outnumber the judges; hence retaining highly skilled judges to rule and write decisions within the time frame is paramount. Using a stakeholder theory approach, this article explores the competency-based development model for judges carried out by the technical training centre of the Indonesian Supreme Court. The research method was descriptive qualitative, purposive sampling for in-depth interviews. The result revealed that each stakeholder, namely technical training managers, supporting lecturers or trainers, working unit, and the public, showed different perspectives on judges' competencies, knowledge, skills, and attitude due to different interests. Stakeholders' views highlighted several points: analytical thinking skill improvement, knowledge application, character building, adaptive skills development and reassignment. This study, therefore, provides a new model of judges' competencies development that emphasizes a throughout human resources management activity application, starting from carrying out apparatus management strategy as a response to bureaucracy reform, strategic environmental changes, and science and information technology development; applying human resources development strategy with stakeholder participation approach through training and development centre; and creating apparatus reassignment strategy. These three strategies lead to an agile civil apparatus to achieve good governance.

Afternoon of “El Satario”: Expanding on the Finding of an Unidentified Print
Authors: Gomes Leonardo
Published: June 2023

Found in the collection of The ArQuives, Toronto’s queer archives, the early pornographic film El satario is believed to have been produced in Argentina between 1907 and 1912, primarily based on the Kinsey Institute’s estimate. This dating is very rarely contested, and the film is widely considered the oldest extant pornographic film, even though its date, as well as its place, of production have never been confirmed. This thesis will investigate what can be expanded from the initial analysis of a found print and the path followed by the researcher in his attempt to understand the social, cultural, and technical context behind the film’s production, circulation, and reception. Each chapter will deal with a broad theme that contributes to contextualizing and unraveling the mysteries of El satario, as well as providing both the reader and the researcher with a broader understanding not only of the film itself but of what revolves around it. 
Quantum Carbon: A New Approach Towards Label-Free Cancer Stem Cell Theranostics
Authors: Ganesh Swarna
Published: June 2023

The primary objective of this thesis is to develop sub 10 nm carbon-based nanoprobes with a potential for detection, monitoring, and treating cancer. The carbon-based nanoprobes were synthesized using ultrashort pulsed laser through the multiphoton ionization process. Early detection of cancer is critical for therapeutic success. Current cancer theranostics primarily focus on cancer cells with a high proliferation rate, whereas recent studies have revealed cancer stem cells (CSC) as the reason for therapeutic failure. The predominant role of CSCs in cancer metastases makes them a clinically relevant target for cancer theranostics. However, existing methods of in vitro detection of CSC are depends on cancer – specific surface markers, which limits the universal application of the detection method. Hence, there exists a need for an ultrasensitive diagnostic method that is used for the detection of CSC irrespective of their tissue origin. In this thesis, the developed sub 10nm carbon nanoprobes were employed for ultrasensitive detection of CSC using SERS. The 3-D quantum Sensor based on graphene oxide, a new phenomenon of single molecule –SERS sensing with an ability to replace plasmonic materials. The next study introduces a unique concept of precisely shrinking a carbon-based organic semiconductor probe, which is used for tag-free genomic DNA detection. Following the single molecule detection, the sub 10nm carbon probes were applied for intracellular detection of cancer, demonstrated by detection of cancer cells, CSC and tumorigenic CSC down to single cellular level. The ability to detect CSC in its fundamental niche provides an insight into the evolution and maintenance of CSC, thereby providing a wholistic detection method of cancer stem cell by probing both the phenotypic and metabolic attributes of CSC. Building upon the efficient detection of CSC and tumorigenic CSC, a self- functionalized CSC theranostic probe was utilized to monitor cancer stem cells and induce therapeutic differentiation through metabolic reprogramming of CSC.

The research performed in this thesis demonstrates a unique carbon-based nanomaterial with different configurations, that can detect CSC down to single cellular level. The contribution rendered towards the synthesis, application, and manipulation of the carbon-based nanomaterials marks the fundamental step towards the early diagnosis, real-time tracking of cancer prognosis non-invasively, and a realizable platform for CSC targeted theranostics.
Fabrication of Free-Standing Structures Using Abrasive/Slurry Jet Micro-Machining
Authors: Azarsa Ehsan
Published: June 2023

Many advanced engineering materials are machined using abrasive water jets, a non-traditional machining method that has certain advantages compared to other approaches. This dissertation aims at developing methodologies to use abrasive water and slurry jets to micro-machine free-standing structures for heat sink and microfluidics applications.

The first aim was to fabricate high aspect ratio free-standing structures with a minimum distance between each other that would lead to maximum heat transfer performance in heat sinks. The effect of machining process parameters on the quality of the resulting free-standing structures was studied. It was demonstrated that high-quality free-standing structures with aspect ratios of more than 40 to be used as fins in heat sinks could be fabricated.

There is an increasing demand for metallic micro-molds that can be used for inexpensive mass production of polymeric microfluidic chips. Therefore, the feasibility of using abrasive water jet micro-machining (AWJM) and abrasive slurry jet micro-machining (ASJM) to fabricate such micro-molds was studied. Jet raster scans under various combinations of process parameters were used in order to machine micro-pockets containing free-standing structures, representing molds for casting microfluidic chips with channel networks. The optimum process parameters and material were determined in order to fabricate the molds with the best possible surface finish.

Because unmasked machining could not be used to fabricate molds with sharp-edged intersecting features, a hybrid AWJM/ASJM masked machining technique was introduced. By careful selection of the process parameters, high quality molds with both single and intersecting free-standing structures at multiple heights could be fabricated, thus making three-dimensional microfluidic chip mold fabrication feasible.

Finally, a new method of mold fabrication that utilized water jet cutting technology to cut free-standing structures out of mild steel sheets, to be used as a mold for PDMS casting, was developed. This enabled 3D features having very abrupt changes in depth with almost 90o angles for use in microfluidic devices. As a proof-of-concept, a polydimethylsiloxane (PDMS) chip was made and tested. It was shown that this alternative approach to create microfluidic molds is versatile and may find utility in reducing the cost and complexity involved in fabricating 3D features in microfluidic devices.
Characterization of a Novel Radiant Floor Panel and a Caisson-Based Geothermal System
Authors: Shukla Saunak
Published: June 2023

The present work investigates two novel technologies: a radiant floor panel and foundation caisson enhanced with phase change material (PCM). The outcome of the research and study on the lightweight novel radiant panel demonstrates several advantages such as retrofittability, ability to respond quickly to building load fluctuations, minimization of unwanted heat transfer towards the ground, cost-effectiveness, and energy savings compared to traditional radiant floor systems seen on the market. The numerical model developed to characterize a foundation caisson enhanced with the PCM demonstrated its ability to address the issue of thermal imbalance when subjected to cooling or heating dominant load profiles. Based on the results of this research, it is expected that without compromising the structural integrity of the foundation caisson and with the selection of an appropriate PCM (considering thermal diffusivity, melting point temperature range, viscosity etc.), an improvement in the thermal performance of the configuration can be demonstrated.
Vision Based Robotic Traversal of Textureless Smooth Surfaces
Authors: Keenan Patrick
Published: June 2023

This study investigates visually localizing and servoing a serial robot’s tooling assembly with respect to a smooth, contoured workpiece surface through the dynamic extraction and leveraging of characteristic surface invariants. A novel formulation for 6 degree-of-freedom (DoF) textureless visual servoing is proposed which significantly extends an existing 3-DoF scheme designed for planar surfaces. A new family of observed feature sets, and their associated interaction matrices are proposed. Curvature conditions on the workpiece shape are derived under which local asymptotic stability for 6-DoF is guaranteed.

The approach naturally, and synergistically, combines the geometric tools of computer aided design, path generation, and computer numerical control (CAD/CAM/CNC) theory, with the manipulator control tools of visual servoing. Design focuses on ease of use by accepting task descriptions in the form of time-parameterized, surface-constrained curves which are compatible with the output of existing path generation systems. Thus, this work is a contribution to the growing collection of integrated-process manufacturing techniques streamlining and extending the traditional CAD/CAM/CNC pipeline. Full surface-relative 6-DoF pose control is achieved with respect to a workpiece which need not be precisely located, or even stationary, in the workspace. Preliminary considerations are also made for a non-rigid workpiece.
Local Ratcheting and Stress Relaxation at Notch Root of Steel Samples undergoing Asymmetric Loading Cycles
Authors: Shekarian Atefeh
Published: June 2023

Engineering components undergoing severe asymmetric loading cycles result in plastic strain accumulation referred as ratcheting. The excess of plastic strain induces damage leading to catastrophic failure in components. The present study intends to evaluate ratcheting response of 1045 steel and 316 stainless steel samples at the vicinity of notch roots with different notch sizes/shapes under various step loading conditions.

To assess progressive ratcheting response and stress relaxation concurrently, the Ahmadzadeh-Varvani (A-V) and Chaboche (CH) kinematic hardening rules were coupled with Neuber’s rule through an algorithm to calculate local stress at the vicinity of notch root in steel samples. Finite element (FE) method was further employed to numerically assess local ratcheting around the notch root through use of ABAQUS software. The predicted results by the A-V and CH hardening rules and simulated outcomes of finite element were later compared with experimental data tested under various uniaxial loading levels, steps, and sequences. Local ratcheting strain values at the vicinity of notch root were found noticeably larger than nominal ratcheting values measured at farther distances from notch edge through use of strain gauges. The higher cyclic stress levels applied at notch root accelerated shakedown over smaller number of cycles and resulted in lower relaxation rate. Notch with larger diameters possessed smaller stress concentration factors and induced smaller plastic zone at notch root promoting ratcheting progress with less materials constraint over loading cycles as compared with notches with smaller diameters.

Local ratcheting response was examined at the vicinity of different notch shapes and sizes as notched samples were tested at different Low-High-High (LHH) and High-Low-Low (HLL) loading sequences. The change of stress level from low to high promoted ratcheting over proceeding cycles while ratcheting strains dropped in magnitude for opposing sequence where stress level dropped from high to low. Predicted ratcheting curves by means of the A-V and CH frameworks as well as those simulated results through FE method resulted in the highest, average and lowest local ratcheting results for steel samples consist of respectively X-ellipse, circular and

Y-ellipse notch shapes. The choice to employ a method of assessment to effectively evaluate local ratcheting response was found to highly dependent on the complexity of approach and related terms, variables and coefficients.
Motivational Hypnosis as a Tool to Eliminate the Effects of Covid-19 Perception on Employee Motivation
Authors: Khéfacha Ahlem , Séllei Beatrix
Published: June 2023

Covid-19's emergence has significantly impacted the world, its workplaces and the motivation of employees. This study aims to determine the impact of how Covid-19 is perceived on employees' intrinsic motivation. It also aims to discover whether a motivational hypnosis session may influence the pandemic's effects, given that hypnosis is a well-known mental intervention that has been used for centuries to treat and help people in domains as varied as therapy, sports, education, and more recently, business. A three-step qualitative experimental study took place, involving ten employee volunteers. The first step was a first questionnaire exploring the effect of their perceptions of Covid-19 on their motivation. A motivational hypnosis session (written to increase employees' intrinsic motivation from the emotional intelligence framework) took place afterwards; the last step was a second questionnaire answered by the workers 48 hours after the session. Results showed that Covid-19 had slightly less of a negative effect on managers' motivation, which was 79% compared to non-executive employees' 87%. The motivational hypnosis session helped only two out of the ten employees to reduce the effects of the way they perceived the pandemic. However, it did have positive impact as it increased employees' intrinsic motivation. Future research on using hypnosis for the benefit of employees should therefore be conducted.

Despite the success of CD19-targeted chimeric antigen receptor (CAR T)-cell therapy in patients with relapsed/refractory large B-cell lymphoma (LBCL), there is a need for effective salvage strategies post-CAR T-cell therapy failure. We conducted a multi-institutional retrospective study of patients who relapsed following CAR T-cell therapy (axicabtagene ciloleucel [axi-cel] or tisagenlecleucel [tisa-cel]) and received salvage therapies (radiation therapy [RT] alone, systemic therapy alone, or combined modality therapy [CMT]). A total of 120 patients with post-CAR T relapsed LBCL received salvage therapies (RT alone, 25 patients; CMT, 15 patients; systemic therapy alone, 80 patients). The median follow-up from CAR T-cell infusion was 10.2 months (interquartile range, 5.2-20.9 months). Failure occurred in previously involved sites prior to CAR T-cell therapy in 78% of patients (n=93). A total of 93 sites were irradiated in 54 patients who received any salvage RT post-CAR T failure. The median dose/fractionation were 30 Gy (range, 4-50.4 Gy) and 10 fractions (range, 1-28 fractions). The 1-year local control rate for the 81 assessable sites was 84%. On univariate analysis, the median overall survival (OS) from the start date of RT was significantly higher among patients who received comprehensive RT versus focal RT (19.1 months vs. 3.0 months; P=<0.001). Twenty-three of 29 patients who received comprehensive RT had limited-stage disease. Among these, there was no difference in median OS among the patients who received RT alone versus those who received RT followed by additional therapies (log-rank P=0.2). On multivariate survival analysis, achieving PR or CR post-CAR T (hazard ratio =0.5; 95% confidence interval: 0.3-0.9; P=0.01) was independently associated with superior OS. Our findings suggest that RT can provide local control for LBCL relapsed post-CAR T-cell therapy, particularly in patients with limited-stage relapsed disease treated with comprehensive RT.

PECULIARITIES OF THE APPLICATION OF TECHNICAL AND FUNDAMENTAL ANALYSIS OF SECURITIES OF UKRAINIAN ISSUERS
Authors: Lyzhnyk Yu. B. , Fedotova T.
Published: June 2023

Objective. The objective of the present article is to study the peculiarities of the functioning of the securities market of Ukraine, in particular its stock market sector, the outline of its main differences from the world stock markets, the determination of the peculiarities of the application of the tools of technical and fundamental analysis of securities to shares. Ukrainian issuers, as well as assess the state of the Ukrainian stock market in war conditions.

Methods. The following methods were used during the research: the dialectical method of learning processes and phenomena (to analyze the peculiarities and state of development of the stock market of Ukraine); graphic (to display stock market index trends); methods of technical analysis (construction of MACD-histograms; construction of Price Oscillator (OSC); calculation of the relative strength index RSI) and fundamental analysis (multifactor forecasting of the share price); abstract-logical method (for forming the resulting research conclusions).

Results. As a result of the study of the peculiarities of the functioning of the Ukrainian securities market, in particular its stock market sector, it was found that the volume of trading in shares and derivative stock derivatives accounts for less than 2% of transactions from the entire stock market of Ukraine, the greater part of which is spent on bond trading, mainly on operations with bonds of domestic government loans.

A specific situation developed on the Ukrainian stock market after the war began: quotations of shares of Ukrainian issuers were suspended and both stock indices were "frozen". For almost six months, the Ukrainian stock market existed only as a government bond market, including a military bond market. Only from August 2022. quotations of shares of Ukrainian issuers on the Ukrainian Stock Exchange resumed. The volume of trade in bonds suffered a decrease due to the war, but not critically, but the volume of trade in shares of Ukrainian issuers decreased almost 5 times.

Taking into account the specifics and characteristics of the securities market of Ukrainian issuers, it is most appropriate to use a combination of fundamental analysis and technical analysis approaches, but in the conditions of excessive volatility of the stock market during the war, the best results are provided by the methods of technical analysis. Multivariate predictive regression and autoregressive models were proposed to predict the BAVL share price.

Objective. The objective of the article is to conduct a contextual linguostylistic analysis of the mono- and syno-slangisms of the British English language range and slang borrowings from the American area in comparison with literary English via the examples of a modern English «working» novel. Methods. The main scientific results are obtained applying a set of general scientific and special methods of research, namely: analysis and generalization of scientific and educational-methodical literature on the problems of the use, formation and translation of slangisms; theoretical generalization, analysis and synthesis; holistic and integral approaches to the study of linguistic phenomena; comparative, descriptive and analytical. Results. Conducted contextual linguostylistic analysis of mono- and syno-slangisms testifies to the presence of a large number of slang words in the works of modern English «working» novelists, as well as to the slang level of Americanism and the tendency of democratization of English colloquial language due to non-literary stylistic expression. The authors note that many slang words, as a result of their frequent use in live spoken language, have become classified and entrenched in literary vocabulary; One of the reasons that prepared the ground for the transition of some slangisms to literary language was the fact that they did not have synonyms in literary English (monolingualisms, of course). The analysis reveals that the greatest number of synonyms are those objects and phe- nomena that play an important role for native speakers; borrowed American slangism, because of its popularity, is being supplanted by the use of purely British slang words. The authors consider various ways of forming slangisms and find out that the greatest difficulties in reading the works of contemporary English «working» novelists is the widespread use by authors of deviations from the literary norm, both phonetic and grammatical.

This study aims to examine the application of the POE (Prediction, Observation, and Explanation) learning model in Mathematics and Natural Sciences learning in the last 10 years in terms of advantages and constraints in Mathematics and Natural Sciences learning at elementary school, junior high school, and senior high school levels. The research used meta-analysis with a quantitative approach and data collection of Scopus/WoS and SINTA journals literature studies on POE in MIPA learning combined with MIPA materials for elementary school, junior high school, and senior high school. The data collection techniques of this research were (1) searching journal and repository databases, (2) data encoding & tabulation, (3) JASP software inputs, (4) interpretation & conclusion: JASP output, moderator variables. The research results showed that applying the POE learning model had a greater effect on student Learning Outcome than on student Critical Thinking with an effect of 60%. Then based on the education level, the POE model's influence on Critical Thinking and Student Learning Outcome was greater at the senior high school level, and based on the material field, the POE model had a greater influence on the mathematics material field. Then the moderator variable showed a very drastic decrease in the effect of the POE model on the Critical Thinking and Learning Outcome of students in 2018-2022, with a RE value of 47% smaller than the previous year. In addition, we recommend that the POE model is better applied at the high school level than at the elementary and junior high school levels.
