Published: September 2023

Feet-lock pipes are installed at the foot of steel arch to limit the displacement, improve the bearing performance of steel arch, and restrict the ground deformation during tunnelling. At present, studies on the design parameter optimization of feet-lock pipes in small-space tunnel are still in a lack, which impedes the application of this technology. In this study, based on a small-space tunnel project in Suzhou, China, the plane strain finite element analysis within the jointed rock constitutive model is conducted to investigate the optimum designs of inserting angle, length, and diameter of feet-lock pipes. Results show that the inserting angle has a significant influence on the supporting efficiency, and an optimal angle of 60° is recommended. The increase of pipe length can lead to the rise of the disturbed zone in the surrounding rock, and the design length is suggested to be below 4.5 m. The pipe diameter has limited influence on the reinforcement effect of tunnels.

Authors: Гривко Антоніна 
Published: September 2023

У статті актуалізовано проблему медійно-інформаційної грамотності (МІГ) учителів. Теоретично обґрунтовано необхідність оцінювання МІГ учителів у рамках внутрішньої системи забезпечення якості освіти у закладах загальної середньої освіти та пошуку (розроблення) відповідного інструменту. Розглянуто різні наукові підходи до визначення дефініційної рамкита структурної концепції МІГ.Запропоновано результати апробації двовимірного опитувальника (особистісний і професійний вимір) для самооцінювання МІГ вчителів для подальшого розроблення рекомендацій щодо можливого вдосконалення і використання його в системі внутрішнього контролю закладів загальної середньої освіти.На прикладі апробаційно-розвідувального дослідження, у якому взяли участь 349 учителів закладів загальної середньої освіти, з’ясовано придатність використовуваного опитувальника для самооцінювання МІГ учителів у межах внутрішньошкільного оцінювання якості освіти. Показано можливості аналізу та інтерпритації результатів опитування. Застосування двовимірної анкети дало можливість порівняти оцінку педагогів власної особистісної та педагогічної МІГ; за результатами кластерного та факторного аналізу визначити значущі групи компонентів МІГ учителів (відповідно до уявлень реципієнтів), побудувати актуальну для досліджуваної вибірки модель МІГ (що дало змогу визначити в її структурі знання та навички, які потребують найбільшої уваги/розвитку). Показано можливість зіставлення результатів самооцінювання МІГ учителів, згрупованих за різними ознаками, наприклад, за приналежністю до закладів освіти за типом населеного пункту, за спеціалізацією – належністю до певної освітньої галузі. У процесі дослідження з’ясовано загальні тенденції розвитку МІГ учителів, зокрема потреби педагогів щодо вдосконалення певних навичок у її структурі. Подальші дослідження можуть бути спрямовані на визначення та методичне обґрунтування заходів для їх задоволення.

<p>This study investigates the business strategies and performance of immigrant-owned firms in Canada through a comparative case study. Based on thematic analysis of two entrepreneurial firms in the restaurant industry – one owned by Chinese and the other by Japanese immigrants, the author uncovers some differences while looking for consistent patterns between the two immigrant groups. The findings show that the immigrant entrepreneurs have all adjusted their business strategies to the external business environment, but their business practice and economic performance are also influenced by the unique resource endowments and cultural characteristics of the immigrant entrepreneurs and their respective communities. Based on these findings, the author discusses the implications for research and policy making. </p>
Modeling and Visual Servoing of Single and Cooperative Continuum Robots
Authors: Norouzi-Ghazbi Somayeh 
Published: September 2023

<p>This thesis dealt with modeling and visual servoing (VS) of continuum robots (CRs) and one of their recently introduced configurations, cooperative-CRs (CCRs). Application-wise, the focus was on small-sized CRs which are a commonly used type of CRs in minimally invasive surgeries (MIS). First, an introduction to continuum robots, and various configurations of CRs were presented. In the next step, kinematic modeling of single-CR and CCRs were presented. Furthermore, dynamic modeling of smallsized CRs was studied. Tendon-driven small-sized CRs include continuous interaction between tendons and backbones, which introduce their own challenges into the modeling. To control the system, firstly, a visual predictive control (VPC) system was employed for a single CR. Many scenarios were simulated to investigate the performance of the control scheme including positioning tasks in the presence and absence of various actuation and visibility constraints, a comparative study between VPC and image-based visual servoing (IBVS) approaches, the effectiveness of the parameter of prediction horizon (Np) on the system performance, the effectiveness of depth estimation and Np on the error and convergence time, and system robustness to the noise of actuators and imaging process. Finally, the system performance was experimentally verified. </p>
<p>In the next step, a new switching VS control approach was developed to control CCRs. As the CCR model is based on Cosserat rod approach, the corresponding differential kinematics is obtained numerically which may result in ill-behaved or computationally expensive Jacobian. To address this issue, a scaled and nondimensional IBVS (SND IBVS) control scheme was introduced which is used to navigate the system at the beginning of the positioning task. The stability of the system is also proved in the sense of Lyapunov. To study the performance of the proposed switching controller, various scenarios were simulated. </p>
<p>Moreover, an experimental set-up for the automation of CRs was developed to be used as the platform for verification of the system controller and to be served as a test-bed for the future studies of this research.</p>
Particle Neutron Gamma-X Detection (PNGXD)
Authors: Van Delinder Kurt W. 
Published: September 2023

<p>This dissertation examines the clinical feasibility of producing a new imaging procedure coined ‘Particle Neutron Gamma-X Detection (PNGXD)’. PNGXD is a newly proposed imaging concept developed specifically for the application of particle therapy. The premise is to take full advantage of the secondary neutrons produced from both the particle treatment unit and from within the patient by capturing them using a pre-administered gadolinium contrast agent (GDCA) located within the tumor volume [1]. </p>
<p>In this thesis, PNGXD was investigated experimentally for proton therapy, a novel method to measure the neutron production was incorporated, and finally, gadolinium (Gd) neutron capture for 10 clinically viable charged particles was studied. In the first section, the first experimental measurements of Gd solution for five different configurations on a Mevion S250 passive double scattering treatment unit were performed. </p>
<p>In the second section, a novel method for measuring slow neutrons using a commercial cadmium-telluride (CdTe) detector as an absolute thermal neutron measurement device on a proton therapy unit was investigated. </p>
<p>In the third section, the potential to produce PNGXD as a result of secondary produced neutrons from 10 different charged particles all of which may prospectively be utilized for particle therapy was investigated. </p>
<p>Lastly, in the final section applications and prospective future studies are discussed regarding the investigation of PNGXD. </p>
An examination of own- and other-race face recognition in adults
Authors: Marquis Alexandra Rose 
Published: September 2023

<p>One of the most well known biases in face perception is the other-race effect – the tendency for observers to show more accurate recognition for own-race compared to other-race faces. Past studies have largely examined face perception using highly standardized photographs in artificial lab contexts, limiting the conclusions we can make about human face recognition. Thus, the purpose of this dissertation was to understand own- and other-race face perception using more naturalistic approaches. In the first manuscript, identity discrimination was impaired across several measures of between- and within-person variability. Both East Asian and White adults performed poorer when perceiving face pairs that were judged as highly similar compared to highly dissimilar. Identity perception was also impaired when the face pair belonged to a different race (e.g., other-race) compared to the same race as perceivers. In the second manuscript, electrophysiological recordings revealed neural identity discrimination responses were impaired for own-race similar compared to dissimilar looking faces. The pattern was the same for other-race face discrimination. Finally, in the third manuscript, change detection was lower when a social partner belonged to a minority race compared to the majority race (i.e., White) only in a less diverse city but not a highly diverse one (Study 3a). Change detection was also lower when social partners belonged to a religious minority and a racial minority (Study 3b). </p>
<p>There was no evidence that change detection was better for own-race compared to other-race individuals across both Studies 3a and b. Taken together, the studies in this dissertation sought to understand how the ORE manifests in contexts that more closely approximate face recognition as it occurs in real life.</p>

Published: September 2023

The Fourth Industrial Revolution stimulated by digital transformation hasimproved the way we live in this world, do our jobs and communicate with each other. The businesses have started to use ICT extensively to improve operations.In fact,Van et al. (2003) findings revealed that investments in technologywere a significant factor in United States better productivity growth than that of Europe in late 1990s.Thus, it becomes imperative for developing nations to devoteresources and adopt ICT in order to increase productivity and beat competition. The present research is an attempt to understand the factors that determine the adoption of ICT by MSMEs that enable them to perform better inemerging economies like India. The present study uses Technology Organisation Environment framework to elicit factors that determine ICT adoption intentions in MSMEs. The results reveal the relative advantage, compatibility of technology and management support have a strong impact on ICT adoption intention of MSMEs. Also complexity of technology has a significant inverse (negative) impact on ICT adoption intention while as decentralised decision making has no impact on ICT adoption intention. Lastly the firms that have high ICT adoption intention tend to have better firm performance.

Regarding the celebration of the Faculty of Chemical Technology and Biotechnology 150 years, we want to highlight our recent results in the Fermentation Pilot Plant Laboratory (F-labor) which have a focus on applied microbiology. In all of our research activities, we first select an appropriate microorganism for the desired tasks, then optimize its cultivation and product formation, finally investigate process scale up and economics. Here we want to shortly summarize and introduce 4 pillars of our recent research topics: 1. carbon capture by microalga cultures, 2. complex utilization of Yarrowia yeasts with main focus on erythtritol production, 3. bacterial formation of biosurfactants and their use against plant pathogenic fungi on the field of agrobiotechnology and 4. development of different fermented cosmetic ingredients with major focus on Lactobacilli. Regarding microalga cultivation among many methodical developments we could build successfully a 850 L scale tank reactor for Spirulina cultivation. In term of Yarrowia non-conventional yeast complex biotechnology utilization was demonstrated from erythritol to cosmetic applications. Agricultural biosurfactants were successfully applied against Alternaria alternata plant pathogenic fungi. Finally Lactobacilli based cosmetic ingredients were proved to be potential skin-moistening agents.

Published: September 2023

Background: Sarcopenia stands as a prominent health concern, exhibiting a notable correlation with chronic lower back pain among the elderly population, with an observed upward trajectory of both conditions within the preretirement age group.
Objective: To examine the prevalence of sarcopenia among individuals in the preretirement age group experiencing chronic nonspecific low back pain, and identify any associated factors.
Methods: This descriptive cross-sectional study included 164 participants, aged 50 to 59 years, from the Department of Rehabilitation Medicine, Faculty of Medicine Ramathibodi Hospital, Mahidol University. Patient data encompassing demographics, physical activity (International Physical Activity Questionnaires, IPAQ), and quality of life (European Quality of Life 5-Dimension 5-Level, EQ-5D-5L) were collected. Sarcopenia criteria, following the Consensus of the Asian Working Group of Sarcopenia (AWGS) 2014, were evaluated through bioelectrical impedance analysis, handgrip dynamometry, and/or the 6-meter walk test. Participants with chronic low back pain underwent assessments of pain severity and functionality.
Results: Of 164 participants (mean [SD] age, 55.1 [2.6] years; mean [SD] body mass index, 24.7 [4.3] kg/m2), IPAQ responses indicated a range from low to moderate activity levels. The health-related quality of life score (median [range]) from EQ-5D-5L assessments stood at 0.94 [0.34 - 1.00]. Sarcopenia was detected in 10 out of 58 subjects (17.2%) with chronic low back pain, and in 6 out of 106 normal subjects (5.7%).
Conclusions: The prevalence of sarcopenia among individuals within the preretirement age group experiencing chronic low back pain was notably high when compared to non chronic low back pain cases, without associated factors.

The most common congenital anomaly and a major contributor to infant and toddler mortality is congenital heart disease (CHD). Although it has high mortality rate but majority of the cases are asymptomatic during early life and usually discovered during routine checkup. To determine the incidence and pattern of congenital heart disease in children in a tertiary care hospital of Bangladesh. This cross-sectional study was conducted among children aged 1 day to 10 years old with cardiac problems who were hospitalized to the Paediatric department of Rajshahi Medical College Hospital, Rajshahi, Bangladesh from August 2018 to August 2021. Early detection of CHD is possible by thoroughly analyzing heart murmurs, clinical manifestations, and outcomes. The data were analyzed utilizing IBM SPSS (version-23). A total of 3512 children under the age of 10 years were evaluated. Here 1.54% of the patients had a CHD murmur. In this study, the most common type of congenital heart illness was a ventricular septal defect (VSD) (37.05%). Atrial septal defect (ASD) (24.07%) was found second most common CHD. Rapid breathing (63%) and poor growth (44.4%) were major clinical presentation. According to types of murmur among patients, 27(50%) had pansystolic murmur, 15(27.77%) had ejection systolic murmur and 12(22.23%) had continuous murmur. Congenital heart disease is a major health concern for Paediatricians due to its significant health hazards and high mortality rate. Early identification of congenital cardiac disease is crucial for preventing complications, lowering mortality, and for proper therapy.

Crotalaria L. is a genus of flowering plants in the family Fabaceae (subfamily Faboideae). Mitotic index is proportionately relevant to cell division rate; mitotic index was found higher (10.38±1.08%) in C. spectabilis and lower (9.43±0.304%) in C. juncea. The nuclear organizations were observed chromocentric in all examined species. The interphase chromosome volume was highest in C. juncea (0.596±0.27 µ³ in meristematic cell and 0.408±0.21 µ³ in differentiated cell) and lowest in C. saltiana (0.205±0.31 µ³ in meristematic cell and 0.16±0.25 µ³ in differentiated cell) which do not correlated with the somatic chromosome number but may be related with environmental condition. The largest cell size was found in C. juncea (20.47±0.49 µm2 in meristematic cell and 106.47±0.63 µm2 in differentiated cell) and the smallest in C. saltiana (14.43±0.39 µm2 in meristematic cell and 45.86±0.21 µm2 in differentiated cell). It was also observed that, the mean value of cell size was larger in differentiated cell compared to meristematic cell in all the studied species of Crotalaria. Chromocenter numbers were found highest (13.66±0.14) in C. saltiana and lowest (9.50±0.32) in C. juncea which are considered as more primitive and more advance in nature, respectively. Percentages of heterochromatin per nuclear area were found highest (14.75±0.71) in C. saltiana and lowest (9.67±0.71) in C. juncea which are considered as more primitive and more advance in nature, respectively.
