Authors: R.T. Al-Wasity  , A. F. Ahmed  , S. A. Albadawi
Published: February 2023

The development of exports in an open economic environment is the best solution in accelerating the pace of economic growth. The research evaluates the competitiveness of Iraqi dates exports based on a set of quantitative indicators and shows the role of Trade activities represented by international marketing that ensures the flow of goods and services from production until they reach the consumer. The research found a competitive advantage for Iraq in its exports of dates, as the Revealed Comparative Advantage - RCA showed a remarkable rise during the years of study and reached 26.98 in 2008, as for the Concentration Index (H), which represents the concentration of exports in a product or a limited number of products. More than 0.5 came in all the years of the study and it reached 0.91 in 2010. That means, the concentration of Iraqi agricultural exports with a large percentage in dates exports, which means placing agricultural exports and the agricultural trade balance in a difficult position if crop production is exposed to shocks that affect the quality and quantity of production, such as epidemic pests, bad weather or price disturbances in global markets. The research recommended using the comparative advantage that distinguishes Iraq in the production of dates and working to increase the market share by finding new marketing channels.

Winding Type Alternation of a Refurbished Old Generator
Authors: Tosun Nail , Gülletutan Görkem , Yakut Muhammet Samet , Yılmaz Deniz Alp , Bayer Özgür , Keysan Ozan
Published: February 2023

Refurbishment of hydro-generators promises an increased lifespan and improved efficiency. Old generators are not only less efficient but also less reliable; their fault occurrence is more common. The economic impact of out-service time can be astronomical. Thus, refurbishment is a critical task; but it is challenging too. Most of the conducted works focus on the material update, enhancing the cooling network, and obtaining better efficiencies. Modifying winding type, i.e. conversion from lap winding to wave winding is rare since it often requires a change in the slot number. Such a move can be laborious, size change can become mandatory. In this study, a refurbishment design strategy is proposed which includes a winding type conversion. The task is to implement a wave winding since it has less out-service time and is easily replaced by field workers. In this paper, an old generator that started operation in 1956 is used for a refurbishment. This study promises a guideline to hydro-generator designers who work on a refurbishment study on old hydro-generators that have diamond coils.
Nonlinear Control Designs And Their Application To Cancer Differentiation Therapy
Authors: Hsiao Yen-Che , Dutta Abhishek
Published: February 2023

This work has been submitted to the IEEE for possible publication. Copyright may be transferred without notice, after which this version may no longer be accessible. 

Objective: We designed three new controllers: a sigmoid-based controller, a polynomial dynamic inversion-based controller, and a proportional-integral-derivative (PID) impulsive controller for cancer differentiation therapy. We compared these three controllers to existing control strategies to show the improvement in performance and compare their robustness.

Methods: The sigmoid-based controller adds a sigmoid term associated with the error of the controlled state and a selected observed state. The sigmoid term is multiplied by a control gain, thereby decreasing the control effort for state transition can decrease. The polynomial dynamic inversion-based controller adds a cubic error term in the error dynamic to achieve a shorter convergence time to the desired value of the controlled state. The PID impulsive controller considers the accumulated controlled state error and the rate of change of the controlled state error, thereby forcing the controlled state to converge to the desired value and alleviating the damping effect in the steady state.

Results: For the considered cancer network, the sigmoid-based controller can reduce the amount of drug dosage to complete state transition compared to existing domain control. The polynomial dynamic inversion-based controller uses less time for differentiation therapy compared to the domain controller. The PID impulsive controller can increase the time interval between each drug dosage and show better robustness compared to vanilla impulsive control.

Conclusion: The 3 new cancer control strategies exhibit superior and robust performance. 

Significance: The PID impulsive controller has a significant improvement in robustness compared to the impulsive controller and has greater potential for cancer differentiation therapy.
Reinforcement Learning Agent Design and Optimization with Bandwidth Allocation Model
Authors: Reale Rafael F. , Martins Joberto
Published: February 2023

Reinforcement learning (RL) is currently used in various real-life applications. RL-based solutions have the potential to generically address problems, including the ones that are difficult to solve with heuristics and meta-heuristics and, in addition, the set of problems and issues where some intelligent or cognitive approach is required. However, reinforcement learning agents require a not straightforward design and have important design issues. RL agent design issues include the target problem modeling, state-space explosion, the training process, and agent efficiency. Research currently addresses these issues aiming to foster RL dissemination. A BAM model, in summary, allocates and shares resources with users. There are three basic BAM models and several hybrids that differ in how they allocate and share resources among users. This paper addresses the issue of an RL agent design and efficiency. The RL agent's objective is to allocate and share resources among users. The paper investigates how a BAM model can contribute to the RL agent design and efficiency. The AllocTC-Sharing (ATCS) model is analytically described and simulated to evaluate how it mimics the RL agent operation and how the ATCS can offload computational tasks from the RL agent. The essential argument researched is whether algorithms integrated with the RL agent design and operation have the potential to facilitate agent design and optimize its execution. The ATCS analytical model and simulation presented demonstrate that a BAM model offloads agent tasks and assists the agent's design and optimization.  
Gateway-based Interoperability for DLT
Authors: Llambias Guzman , Bradach Bruno , Nogueira Juan , González Laura , Ruggia Raúl
Published: February 2023

Blockchain is a distributed ledger technology (DLT) to manage data in a decentralised way. During the last years, interoperability has become one of the main challenges within blockchain research as blockchains increasingly require integration between each other. Indeed, blockchains work by design in silos of information as interoperability is not a native feature. The main efforts in the field are focused on blockchains, such as Bitcoin and Ethereum. However, interoperability in DLT remains as an almost untouched area of work as they introduce additional requirements focusing on privacy and identity. Although there are some interoperability solutions for DLT, they are either high-level design proposals not providing concrete implementations or focus on interoperability issues between business applications and blockchain platforms. In this paper we propose a gateway-based platform-to-platform interoperability solution for DLT, which comprises a detailed solution design and a reference implementation. The proposal was assessed through the development of a social security case scenario and the evaluation through two interoperability frameworks. A reference implementation was built using two DLT: Hyperledger Fabric and Corda. The experimental results shows that it is possible to achieve technical interoperability between two heterogeneous DLT platforms using a gateway-based interoperability solution, relaxing decentralisation, data privacy, identity and authorisation management properties.

Students’ Priority on the Entrepreneurship Program Success: A Basis for Restrategizing Entrepreneurship Approach
Authors: Mirano Cirilo E. , Jr Jr , Ines Joefrelin C.
Published: February 2023

Entrepreneurship plays a significant role in pursuing economic diversification to address too much reliance on oil and gas which was estimated in 2012 to last for 20 years. Entrepreneurship program/education was introduced to various higher educational institutions across all programs and disciplines to encourage and equipped the students to engage in a business that can also address increasing unemployment through job creation. However, most of the students preferred to be wage employees. A focus group was created and identified student priorities which are categorized according to Opportunities, Motivation, and Incentives. 243 out of 658 Advanced Diploma and Bachelor students of UTAS-Shinas were selected through a combination of purposive sampling and simple random sampling. A survey questionnaire was used to gather data on student priorities or factors using a 5-point Likert scale and the data were analyzed using sample mean and two-tailed independent sample t-test. Results showed 62.14% of the respondents preferred to be wage employees. Respondents also agree that opportunities and incentives contribute to entrepreneurship success however, respondents do somewhat agree that motivations could contribute to entrepreneurship success with a mean of 2.69. Results suggest that there is a statistically significant difference in the response based on academic level, after graduation preference, and existing (family-owned) business with a p-value of p=0.013, p=0.002, and p=0.005 respectively except gender p = 0.064. The result signifies that while students’ priority leads to entrepreneurship program success, respondents greatly rely on the sustainability and the intensity of future monetary benefits and economic incentives. Though the academic and government/private finance and technical support elements of the model may be assumed to work perfectly, the success of the entrepreneurship program warrants collaborative effort to initiate a paradigm shift on students’ priorities/factors.

Published: February 2023

Background: Human epidermal growth factor receptor 2 (HER2) overexpression and amplification have been considered as a therapeutic and prognostic target in a quantity of tumors although conflicting data exist about the incidence and clinical consequence of HER2/neu status in the patients. The growth risk of bladder cancer is age dependent. In general, adolescent and young adults tend to develop well differentiated non-invasive, rather than invasive bladder cancer. Objectives: The aim of this study is to assess the Immunohistochemical study of HER-2/NEU Expression in urothelial bladder carcinoma and its correction with histopathological Grade. Methods: This was a cross sectional study. Patients with paraffin blocks of urinary bladder tissue which were histologically diagnosed as urothelial carcinoma at the Department of Pathology, BIRDEM and other private laboratories were included in our study during the period of January 2016 to December 2018. Results: This study shows that, a total of 56 histologically diagnosed cases of urothelial carcinoma were included. There were 34 cases (60.7%) of high grade and 22 cases (39.3%) of low-grade urothelial carcinomas. The age of the patient ranged from 23 years to 98 years (mean 66.34±15.3 years). Majority of patients (50.98 %) belonged to 61 to 80 years age group. High grade tumors were predominantly seen at an older age. There were 42 males (75.0%) and 14 females (25.0 %) with a male to female ratio of 3:1. Conclusions: Significant correlation in expression of HER-2/Neu was found with grading of urothelial carcinoma. A positive HER-2 status is associated with aggressive urothelial carcinoma and provides independent prognostic information for urothelial carcinoma recurrence and mortality.

Szkic do biografii pedagogicznej Bogdana Nawroczyńskiego
Authors: Dziaczkowska Lucyna
Published: February 2023

Prezentowany tekst nawiązuje do wyrażonego przed laty pragnienia wybitnego polskiego pedagoga – Bogdana Nawroczyńskiego – by powstawały w naszym kraju autobiografie, mające na uwadze zgłębienie doświadczenia wychowania ich autorów. Sam Nawroczyński pozostawił po sobie bogaty materiał pamiętnikarski w napisanych pod koniec życia Wspomnieniach starego pedagoga. Zostały one tu wykorzystane do nakreślenia swoistego szkicu biografii pedagogicznej – czyli biografii skupiającej się na szukaniu odpowiedzi na pytania: jakie osoby, jakie sytuacje i zjawiska, jakie przedmioty oraz instytucje, miały w życiu konkretnego człowieka – tu wybitnego naukowca – moc wspomagania jego rozwoju; jak to się działo, że określone czynniki stawały się znaczące dla aktów i procesu jego kształcenia w ciągu całego życia? Podstawą dla strukturalizacji tego tekstu stała się jedna z fundamentalnych tez teorii wychowawczego rozwoju autorstwa Stefana Kunowskiego, iż podstawowymi siłami dynamizującymi ten proces są: 1) bios – jako siła biopsychologicznego potencjału rozwojowego, 2) etos – jako siła społecznego nacisku, 3) agos – jako siła świadomej obecności wychowawczej, ukierunkowanej na urzeczywistnianie świata wartości, 4) los – jako siła łącząca niezależne od człowieka zdarzenia z twórczym i odpowiedzialnym angażowaniem się w samokształtowanie.
Patrones comerciales México-EUA y México-China
Authors: Gutiérrez Rodríguez Roberto
Published: February 2023

Para comprender la complejidad de las relaciones de México con sus dos principales socios comerciales, Estados Unidos y China, se trabaja en tres direcciones: el nivel de competitividad de la economía mexicana frente a ambas; el tipo de inserción comercial de los tres países, y la medida en que los flujos comerciales de México hacia ellos se ajustan o alejan de las predicciones teóricas del modelo complementarista Heckscher-Ohlin. Se recurre a tres instrumentos empíricos desarrollados a medida que se transita de la teoría tradicional a una nueva teoría del comercio internacional: los índices bilaterales de intensidad comercial; los índices bilaterales de ventaja comparativa revelada, y el grado de integración de las industrias, a partir del índice de Grubel y Lloyd. Los hallazgos respecto a Estados Unidos son elevados niveles de integración, reflejados en la intensidad del comercio bilateral y en un alto índice de Grubel y Lloyd, mayor después de la pandemia de la Covid-19. Con China, alta intensidad comercial en una sola dirección y un índice de Grubel y Lloyd que, después de haber crecido sostenidamente, muestra signos de agotamiento a partir de la pandemia, lo que por una parte refleja un patrón de comercio tradicional, a la Heckscher-Ohlin y, por otra, los incipientes efectos de las restricciones comerciales impuestas por Estados Unidos.

Traitement des effluents de désulfuration des gaz d’échappement des navires de transport maritime par filtration membranaire
Authors: DROUIN M. , PARRAVICINI G. , NASSER S. , MOULIN P.
Published: February 2023

En 2020, la concentration en oxyde de soufre autorisée dans les fumées de gaz d’échappement des bateaux de la marine marchande a été réduite d’un facteur 7 par l’Organisation maritime internationale. Pour satisfaire ces nouvelles normes de rejet atmosphérique, les armateurs ont adapté leurs navires et des systèmes de désulfuration des gaz d’échappement ont été installés. Ces unités couplent, d’une part, un procédé d’absorption gaz-liquide pour l’épuration du gaz et, d’autre part, un procédé membranaire pour le traitement des eaux de lavage. L’objectif de la présente étude est d’optimiser ce procédé membranaire. Des membranes d’ultrafiltration multitubulaires en carbure de silicium sont utilisées. La filtration est réalisée à flux constant avec l’application de rétrolavage à intervalle régulier. Les effluents à traiter proviennent directement des navires maritimes étudiés et, après caractérisation de chacun d’eux, ils ont été classifiés comme des fluides à fort ou à faible pouvoir colmatant pour la membrane. Les paramètres opératoires de filtration appliqués varient en fonction des propriétés du fluide. L’influence des paramètres de rétrolavage : fréquence, durée et/ou mode d’injection sur les performances de filtration et de rétention de la membrane est également étudiée. Ainsi il est montré que l’application d’action de décolmatage rapide (inférieur à 5 secondes), et sous pression (3 bars) permet de maintenir la filtration sur plusieurs heures. La réversibilité de la perméabilité est de l’ordre de 80 % et d’importants taux de récupération en eau, supérieurs à 75 %, sont obtenus en fonction du flux de perméat appliqué. En matière de rétention, 100 % des particules en suspension et 80 % en métaux lourds sont éliminés, ce qui permet un rejet dans l’environnement.

Authors: Kużdowicz Kamila
Published: February 2023

W pracy przedstawiono charakterystykę cech morfologicznych i użytkowych 20 materiałów kolekcyjnych buraka pastewnego z Banku Genów Krajowego Centrum Roślinnych Zasobów Genowych w Radzikowie. Badania prowadzone były w latach 2010–2012 metodą losowanych bloków w dwóch powtórzeniach. Kontrolę stanowiły dwie odmiany buraka pastewnego (Mars Poly, Tytan Poly). W badaniach wykonano analizę takich cech jak: masa liści, masa, kształt i kolor korzenia, zagłębienie korzenia w glebie, plon korzeni i suchej masy oraz skład chemiczny korzeni (zawartość cukru, potasu, sodu oraz azotu α – aminowego). Przeprowadzone badania wskazują na znaczne zróżnicowanie materiałów kolekcyjnych buraka pastewnego pod względem wielu cech morfologicznych i użytkowych. Charakterystyka i ocena form uprawnych buraka wzbogaca istniejące bazy danych i czyni je użytecznymi w programach hodowlanych i badawczych.

Published: February 2023

W pracy przedstawiono zmiany w plonowaniu, zawartości oraz pobraniu fosforu i siarki przez rutwicę wschodnią. Doświadczenie polowe prowadzono na polu doświadczalnym należącym do Uniwersytetu Przyrodniczo — Humanistycznego w Siedlcach. W badaniach uwzględniono trzy obiekty ze zróżnicowanym nawożeniem azotowym (N34, N68, N102). W każdym roku prowadzenia badań zbierano trzy pokosy rutwicy w fazie pąkowania. Całkowitą zawartość fosforu i siarki w roślinie i w glebie oznaczono na spektrofotometrze emisyjnym z plazmą wzbudzaną indukcyjnie (ICP-AES). Obliczono pobranie analizowanych pierwiastków z plonem suchej masy rośliny testowej. Azot zastosowany w kolejnych dawkach istotnie wpłynął na zmniejszenie plonu, zawartości i pobrania fosforu przez rutwicę wschodnią. Zastosowane nawożenie azotowe istotnie zróżnicowało zawartość siarki w suchej masie rutwicy wschodniej. Najwięcej siarki oznaczono w roślinie testowej nawożonej dawką N102. Największe ilości siarki z plonem pobrała rutwica nawożona dawką N34. W glebie pobranej z obiektu N34 oznaczono najwięcej fosforu i siarki.

Badania polowe przeprowadzono w latach 2005–2007. Doświadczenie założono jako dwuczynnikowe, metodą losowanych podbloków w trzech powtórzeniach. Badanymi czynnikami były: dwie odmiany ziemniaka — Irga i Balbina i cztery sposoby pielęgnacji z udziałem herbicydów: Plateen 41,5 WG, Racer 250 EC, Sencor 70 WG i obiekt kontrolny — pielęgnacja mechaniczna. Celem badań było określenie wpływu sposobów pielęgnacji ziemniaka na liczbę chwastów i plon handlowy dwóch odmian ziemniaka jadalnego. Najmniejszą liczbę chwastów określoną przed zwarciem rzędów i przed zbiorem bulw stwierdzono na obiekcie opryskiwanym herbicydem Sencor 70 WG. Stwierdzono istotne ujemne zależności pomiędzy liczbą chwastów a wielkością plonu bulw.
Dziedziczenie cechy wiechowatości kwiatostanów lucerny mieszańcowej (Medicago x varia T. Martyn)
Authors: Bodzon Zbigniew
Published: February 2023

Obiektem badań była spontaniczna mutacja lucerny, polegająca na wyrastaniu dodatkowych gron w miejscu kwiatów. Kwiatostan zmutowanych form przybiera kształt wiechy (pi — panicle inflorescence) złożonej z kilkunastu rozgałęzień, na których wyrastają kwiaty. Liczba kwiatów w wiechach, w porównaniu z gronami, ulega zwielokrotnieniu osiągając liczbę kilkudziesięciu. Wykorzystanie tej cechy w hodowli lucerny stwarza nowe możliwości zwiększenia jej potencjału plonowania nasiennego. Celem badań, wykonanych w latach 2005–2010, było określenie sposobu dziedziczenia cechy wiechowatości kwiatostanów. Ocenę ekspresji tej cechy przeprowadzono w obrębie potomstw S1 i S2, pochodzących z samozapyleń rośliny zmutowanej oraz mieszańców F1, F2 i F3, uzyskanych ze skrzyżowania roślin wytwarzających typowe kwiatostany (grona) z roślinami zmutowanymi. Analiza stosunków rozszczepień fenotypowych, przeprowadzona z użyciem testu chi-kwadrat, wykazała, że cecha wiechowatości kwiatostanów lucerny dziedziczy się jednym genem w układzie czterech alleli recesywnych (pi pi pi pi).

The fourth industrial revolution emerges from a demanding need for reskilling and upskilling every active working person. Furthermore, the European Commission included key policy instruments for resilience, social fairness, and sustainable competitiveness in the European Skills Agenda. Distance training and education programs are key factors to succeed in the targets mentioned above. Due to the o COVID-19 pandemic, already 30% of the total education in European countries has further expanded. As a result, online evaluation approaches are more than necessary. Various methodologies have been applied to evaluate the online training sessions, from traditional statistics to context analysis and, the newly introduced text mining and sentiment analysis. This work used conventional descriptive statistical methods and advanced text mining methods to analyse data collected by private sector online training seminars—a total of 50 trainees in 5 seminars conducted by the private sector during COVID-19 pandemic training activities. A typical text mining analysis performed on a low is some open questions and a small number of texts.

In der vorliegenden Arbeit wurde ein Referenzbauteil für die Materialextrusion (MEX) entwickelt. Es wird ein Vorgehen beschrieben, wie zweistufig die Bauteilqualität des Referenzbauteils beurteilt werden kann. So erfolgt zum einen eine qualitative optische Beurteilung des Referenzbauteils und Einstufung in eine Qualitätsstufenmatrix und zum anderen eine qualitative Messung der Bauteilfeatures mit 3D-Scanner und einer nachgelagerten Abweichungsanalyse der Soll- und Ist-Geometrie.

 

This paper describes the development of a novel reference part for material extrusion (MEX, formerly known as FDM). It presents a two-step quality evaluation procedure for the reference part. Briefly, first, the reference part will be assessed optically and ranked according to a pre-defined quality matrix. Subsequently, quantitative measurement using a 3D scanner will be used to analyze the deviation between the target and the real geometry.

Published: February 2023

Mittels grünem Laser lassen sich beim pulverbettbasierten Schmelzen filigrane Strukturen für Hochleistungswärmetauscher fertigen. Dabei spielt, neben dem additiven Fertigungsprozess, die Oberflächennachbearbeitung eine wesentliche Rolle. Es wurden geeignete Nachbearbeitungsverfahren miteinander verglichen, Abträge quantifiziert sowie eine Prozesskette für Kupferbauteile abgeleitet. Mithilfe der Ergebnisse lassen sich Strukturen mit einer Feinheit von bis zu 135 µm prozesssicher herstellen.

 

Filigree structures for high-performance heat exchangers can be manufactured using green lasers in powder bed fusion. In addition to additive manufacturing of the geometry, surface finishing plays an important role. Thus, suitable post-processing methods were compared, ablation was quantified, and a process chain for copper components was derived. The results enable the reliable production of structures with a fineness of up to 135 µm.
