Structural Dependence of Extended Amide III Vibrations in Two-Dimensional Infrared Spectra
Authors: Brüggemann Julia , Chekmeneva Maria , Wolter Mario , Jacob Christoph
Published: October 2023

Two-dimensional infrared (2D-IR) spectroscopy is a powerful experimental method for probing the structure and dynamics of proteins in aqueous solution. So far, most experimental studies focus on the amide I vibrations, for which empirical vibrational exciton models provide a means of interpreting such experiments. However, such models are largely lacking for other regions of the vibrational spectrum. To close this gap, we employ an efficient quantum-chemical methodology for the calculation of 2D-IR spectra, which is based on anharmonic theoretical vibrational spectroscopy with localized modes. We apply this approach to explore the potential of 2D-IR spectroscopy in the extended amide III region. Using calculations for a dipeptide model as well as alanine polypeptides, we show that distinct 2D-IR cross-peaks in the extended amide~III region can potentially be used to distinguish \alpha-helix and \beta-strand structures. We propose that the extended amide III region could be a promising target for future 2D-IR experiments.
Simulating the Excited-State Dynamics of Polaritons with Ab Initio Multiple Spawning

Published: October 2023

Over the last decade, there has been a growth of interest in polaritonic chemistry, where the formation of hybrid light-matter states (polaritons) can alter the course of photochemical reactions. These hybrid states are created by strong coupling between molecules and photons in resonant optical cavities and can even occur in the absence of light when the molecule is strongly coupled with the electromagnetic fluctuations of the vacuum field. We present a first-principles model to simulate nonadiabatic dynamics of such polaritonic states inside optical cavities by leveraging graphical processing units (GPUs). Our first implementation of this model is specialized for a single molecule coupled to a single photon mode confined inside the optical cavity, but with any number of excited states computed using complete active space configuration interaction (CASCI) and a Jaynes-Cummings type Hamiltonian. Using this model, we have simulated the excited-state dynamics of a single salicylideneaniline (SA) molecule strongly coupled to a cavity photon with the ab initio multiple spawning (AIMS) method. We demonstrate how the branching ratios of the photo-deactivation pathways for this molecule can be manipulated by coupling to the cavity. We also show how one can stop the photoreaction from happening inside an optical cavity. Finally, we also investigate cavity-based control of the ordering of two excited states (one optically bright and the other optically dark) inside a cavity for a set of molecules where the dark and bright states are close in energy.
A Sulfur Monoxide Surrogate Designed for the Synthesis of Sulfoxides and Sulfinamides
Authors: Austrup David , Saito Fumito
Published: October 2023

Sulfur monoxide (SO) is a highly reactive species that cannot be isolated in bulk. However, SO can play a pivotal role as a fundamental building block in organic synthesis. Reported herein is the design and application of a sulfinylhydrazine reagent as an easily prepared sulfur monoxide surrogate. We show facile thermal SO transfer from this reagent to dienes where a reaction using a mechanistic probe suggests the generation of singlet SO. Combined with Grignard reagents and appropriate carbon or nitrogen electrophiles, the reagent serves as an effective “SO” donor to enable the one-pot, three-component synthesis of sulfoxides and sulfinamides.
Carboxylic Acid-Catalyzed Controlled Ring-Opening Polymerization of Sarcosine N-Carboxyanhydride: Fast Kinetics, Ultra-High Molecular Weight, and Mechanistic Insights
Authors: Wang Shuo , Lu Ming-Yuan , Wan Si-Kang , Lyu Chun-Yan , Tian Zi-You , Liu Kai , Lu Hua
Published: October 2023

The rapid and controlled synthesis of high molecular weight (MW) polysarcosine (pSar), a potential polyethylene glycol (PEG) alternative, via the ring-opening polymerization (ROP) of N-carboxyanhydride (NCA) is rare and challenging. Here, we report carboxylic acid-catalyzed well-controlled ROP of Sar-NCA, which accelerates the polymerization rate up to 50 times, and enables the robust synthesis of pSar with unprecedented high molecular weight (MW) up to 586 kDa (DP ~ 8200) and exceptionally narrow dispersity (Ð) below 1.02. Density functional theory (DFT) calculations combined with mechanistic experiments identify the carbamic acid as dormant species before generating the secondary amine for chain propagation, and elucidate the role of carboxylic acid as a bifunctional catalyst that significantly facilitates proton transfer processes and avoids charge separation. High MW pSar demonstrates improved thermal and mechanical properties over low MW pSar. This work provides a simple yet highly efficient approach to ultra-high MW pSar and generates new fundamental understandings useful not only for the ROP of Sar-NCA but also other NCAs.
Control engineering remote lab: design and hands on practice with a DC motor speed controller. Laboratorio remoto control
Authors: Cuero Ortega Jairo David
Published: October 2023

The COVID-19 pandemic had a significant impact on education worldwide, prompting the adoption of virtual learning at all educational levels as a solution to overcome distance barriers, providing flexible study schedules and producing digital content to support adaptive learning. Educational institutions quickly adjusted their curriculum to enable uninterrupted learning in response to the new reality. However, implementing virtual education was challenging, particularly in terms of technology accessibility. Not all students had access to appropriate devices and connectivity, leading to a digital divide. Additionally, the lack of face-to-face interaction posed challenges for students as they adjusted to diverse learning platforms and grappled with uncertainties about the pandemic's impact on their future. The isolation also affected curricula, resulting in the cancellation of corporate internships and hands-on activities, particularly in engineering disciplines that rely on practical components. As a result, engineering institutions and educators advocated for methodologies that incorporate virtual and distance learning tools. Two noteworthy alternatives are Virtual Laboratories and Remote Laboratories. Virtual laboratories employ simulators to replicate real environmental conditions, while remote laboratories enable students to manipulate experiments in authentic laboratories via the Internet remotely. This study focuses on developing a remote laboratory for hands-on practices in control engineering, specifically involving a DC motor, using the Internet of Things (IoT) protocol. The laboratory incorporates a motor connected to a development board with MQTT protocol-based messaging services, a lightweight and widely used IoT protocol. The laboratory's web page hosted on the server facilitates data transmission and reception, along with real-time video streaming for users to observe the motor's operation. By using the remote laboratory, students gain access to a standardized control device, enabling the application of theoretical knowledge in control systems. They can experimentally determine system transfer functions through identification or modeling, design controllers, and test them on the physical platform, all from the comfort of their homes. To summarize, remote laboratories have been valuable tools in engineering education, addressing the challenges caused by the COVID-19 pandemic. These laboratories enhance the learning process by providing access to practical experiences and advanced resources, consolidating theoretical concepts, and offering students greater flexibility in their educational journey.

Published: October 2023

In this study we explored Facebooking as a novel strategy in language teaching that utilizes Facebook vocabulary and discourse structure. Grounded in the Interaction Hypothesis of Second Language Acquisition and drawing on Vygotsky's Social Constructivist Theory (Vygotski, 1986), we employed a qualitative design to examine the effectiveness of this strategy. In the study, we used a questionnaire and observations to get the necessary data and employed interviews to validate the data from the teacher-participant and student-respondents. The results unveiled that incorporating Facebook vocabulary, including "post," "comment," "share," "tag," "wall," "timeline," "poke," "administrator," "offline," "online," and "loading", led to a notable increase at student participation level and facilitated the development of their spoken discourse. The familiarity and enjoyment associated with using Facebook contributed to students' active engagement in the classroom. The Facebook discourse structure can be applied effectively in language teaching, aligning it with the instructional components provided by the Department of Education. The recommendation of this study is that L2 teachers and material developers incorporate familiar and enjoyable aspects of Facebook in their teaching to create a dynamic and engaging classroom environment that promotes active student involvement. While this study acknowledges its limitations, future research should explore other age groups and different topics within the English classroom. Additionally, incorporating a quantitative design can further validate the findings presented in this study. Overall, integrating Facebook vocabulary and discourse structure offers a fresh perspective in the field of language teaching.

Published: October 2023

One of the causes of students' low higher level thinking abilities is the use of teaching strategies. This research aims to investigate the role of higher order thinking skills teaching strategies to improve students' critical thinking skills in science learning. The research design used was quasi-experimental by dividing students into three groups, namely the experimental class which received teaching strategy intervention that encouraged higher level thinking skills, while the other two groups were students majoring in science and non-science who received traditional teaching intervention. The participants involved were 300 vocational school students. The instruments used in this research are critical thinking skills assessment instruments, dispositions observation sheet of teaching strategies used by the teacher, and question sheets that reveal the teacher's perspective on higher order thinking skills. Quantitative analysis was applied to the data and included descriptive statistics and ANOVA tests and was strengthened by qualitative data analysis using analysis of interview results. Research findings show that students in the experimental group showed significant improvements in all components of critical thinking and dispositional aspects. The increase in critical thinking skills appears significant in all aspects, namely evaluative, identification and inference. Improvements in the disposition aspect can be seen in the ability to seek the truth, the ability to open one's mind, self-confidence, and maturity in facing problems. In addition, teaching designed to improve high-level thinking skills has intensity in several activities such as always presenting problems in context, open discussions, encouraging students to experiment, being inquiry-oriented, and providing many opportunities to develop critical thinking skills. This research means that students' critical thinking abilities can be improved by designing teaching that integrates several methods that encourage them to think critically. Researchers recommend the need for teacher professional development programs, especially in the use of teaching strategies that encourage higher order thinking skills in the teaching process.

Reliability-based analysis of seismic bearing capacity of shallow strip footings resting on soils with randomly varying geotechnical and earthquake parameters
Authors: Bendriss Faiçal , Harichane Zamila
Published: October 2023

Seismic bearing capacity of strip footings is a challenging task for geotechnical engineers due to its stochastic framework instigated by the natural uncertainties incorporated into geotechnical properties and earthquake parameters. Consequently, the introduction of the random field theory into reliability analysis may provide power tools to succor designers check how reliable their designs. This paper aims to assess the seismic bearing capacity of shallow strip footings resting on soils with randomly varying parameters. Bearing capacity formulas for purely cohesive and cohesive-frictional soils are considered. The influence of the type of the autocorrelation functions (ACFs), the scale of fluctuations (SOFs) and the coefficient of variation (COV) of the random parameters are investigated. Statistical moments, probability density function (PDF) and failure probability (Pf) of the seismic bearing capacity are computed. It is shown that the Single Exponential (SNE) ACF is the most appropriate function to characterize the spatial variability of the soil properties since it provides conservative results. On other hand, the results indicate that the increase in the coefficients of variation (COV) of the cohesion or the friction angle increases the variability of the seismic bearing capacity while this variability remains unaffected when the COV of the seismic coefficient increases. The results also highlight that the effect of the vertical SOF on the PDF and the failure probability is much more significant than that of the horizontal SOF. In addition, the mean seismic bearing capacity fluctuates slightly as the horizontal or vertical SOF increases so that the increment of variation is between 0.4% and 2% for the both two soil types.

El objetivo fue conocer la percepción de los profesores de Educación Física (EF) sobre la pertinencia de la Priorización Curricular (PC) de la asignatura de Educación Física y Salud (EFS) en tiempos de pandemia. Es un estudio piloto con enfoque cuantitativo, no experimental transversal con alcance descriptivo de tipo exploratorio. Se aplicó un cuestionario a profesores que estaban ejerciendo su profesión en establecimientos educacionales ubicados dentro de la provincia de Talca, Chile. Los principales resultados indican que el 80% de los docentes tiene bastante conocimiento sobre este instrumento (PC), aunque casi el 70% sostiene que este no contribuye en el desarrollo integral de los estudiantes. Sobre el 70% de los encuestados indicó que la PC debería reestructurarse bajo criterios según la realidad del contexto educativo en el que se desenvuelven, al mismo tiempo, casi el 80% estableció que la PC actuó de manera positiva como respuesta educativa durante la pandemia por COVID-19. Se concluye que la PC, desde el punto de vista de los sujetos participantes de este estudio, no es pertinente frente a la respuesta inmediata del Ministerio de Educación de Chile [MINEDUC] como propuesta de enseñanza a través de los objetivos priorizados, por lo mismo esta requiere una reestructuración ante situaciones similares en un futuro.

Background: Maternal-fetal attachment is a multidimensional phenomenon and product of diverse physiological, psychological, and socio-emotional factors. Prenatal period plays a crucial role in forming this bond and further predicts post-natal attachment.

Methods: The present research was conducted using cross-sectional survey design. 66 participants filled the survey regarding practices, perceptions and attitudes of maternal-fetal attachment, after attending an online session on “Talking to the Baby in the Womb”.

Results: Analysis revealed that participants eat healthy during prenatal period and talk to their baby in tummy. Wondering when the baby starts thinking, feeling and hearing within also aids in forming maternal-fetal relationship. Statistically significant difference (p=0.013) was found between HCP and PW in terms of attitude towards feeding the baby and perception of mother giving up for the baby (p=0.04).

Conclusion: Following research allows us to study the differences in the practices between healthcare providers and pregnant women so that interventions can be designed accordingly.

Background: Pakistan is a country where women's education has been a topic of discussion for decades. Despite the government's efforts to improve the literacy rate and promote education, many challenges still prevent women from gaining access to education. This research paper explores the challenges and opportunities for women's education in Pakistan and how to overcome those challenges.

Methodology: The study qualitatively analyzed the existing literature on women's education in Pakistan. Using data from the Pakistan Demographic and Health Surveys, articles from Academic Journals, Reports, chapters, and Newspapers. The analysis is based on the challenges and opportunities for women's education in Pakistan. 

Results: Pakistan's literacy rate is 46%, with a significant urban-rural divide, with 80% literacy in urban areas and 20% in rural areas. Cultural norms and conservative attitudes towards gender roles, poverty, lack of educational facilities, security, and a scarcity of female teachers are the main challenges to women's education in Pakistan. However, the government of Pakistan is trying to improve women's education through initiatives like girls' schools, scholarships, e-learning, and technology.

Conclusion: women's education in Pakistan faces numerous challenges, including cultural norms, poverty, and lack of educational facilities.

Globalization-Female Labour Participation Nexus in Pakistan: A Dynamic Analysis.
Authors: Azeema Begum
Published: October 2023

Background: The process of globalization is defined as a process of integration with the globe through trade, foreign investment, and the transfer of technology and migration from one region to another. There is a need to investigate whether increasing dependency and interconnectedness among various regions can bring any advantage for female labor while opening a new venue or creating hurdles. The main objective of this study is to empirically investigate the impact of globalization on female labor participation using time series data. This study also considers the impact of the economic situation, education, and health on the female labour supply in Pakistan.

Methodology: Female labour force participation rate is a dependent variable, whereas; Globalization Index, Economic Misery Index, school enrolment ratio, fertility rate, and GDP growth are independent variables. The ARDL bound testing approach has been used for data analysis to estimate the model. The time series data was collected from secondary data from 1973 to 2019.

Results: The study's finding proves globalization's negative and significant impact on female labour participation in Pakistan. The increasing trend of globalization is not supporting domestic employment opportunities for females. Rather, it pushed females back from the labor market due to the demand for more skilled labor and the replacing human labor with technology. Moreover, the lack of education and health facilities and the worse economic situation have overturned globalization's positive effects on females. 

Conclusion: Based on the study's findings, it is suggested to improve female skills through investment in different education, training, and skills development programs to cope with the imminent challenges of globalization on females in Pakistan. Even though researchers have highlighted the impact of globalization on female labour, however; it has not been investigated comprehensively in the context of Pakistan. This study aims to fill this gap by investigating the impact of globalization on females, considering the Economic Misery Index, school enrolment ratio, fertility rate, and GDP growth.
Le système africain de protection des droits de l’homme et le droit international humanitaire
Authors: Abelungu Junior Mumbala , Cirimwami Ezéchiel Amani
Published: October 2023

RÉSUMÉ: Cet article examine la manière dont le système africain de protection des droits de l’homme appréhende le droit international humanitaire (DIH) ou résiste à l’aborder. L’analyse se base essentiellement sur la pratique de la Commission et de la Cour africaines des droits de l’homme et des peuples. L’article examine d’abord si la Commission et la Cour africaines des droits de l’homme et des peuples peuvent interpréter et appliquer les instruments de DIH. Il y répond par l’affirmative. Il analyse ensuite la pratique de ces deux institutions et constate que dans les affaires où celles-ci ont eu l’opportunité d’interpréter ou d’appliquer les règles de DIH, elles se sont caractérisées par une réticence. Enfin, en perspective de la nouvelle Cour africaine de justice, des droits de l’homme et des peuples, en sa section de droit international pénal, l’article s’interroge également sur l’avenir de l’interprétation et de l’application du DIH.
 
TITLE AND ABSTRACT IN ENGLISH: The African human rights system and international humanitarian law
ABSTRACT: This article examines the way in which the African human rights system tackles or resists to tackle issues relating to international humanitarian law (IHL). The analysis conducted therein is essentially based on the practice of both the African Commission of Human and Peoples’ Rights and the African Court of Human and Peoples’ Rights. In examining whether the African Court and the African Commission may interpret and apply IHL instruments, this article argues that they do in fact have the power to do so. However, on the basis of a close scrutiny of both the Commission and the Court’s practices, the authors note that in instances where the two bodies could have applied IHL norms and standards, they have refrained from doing so. In the last part, the article questions the prospect of the interpretation and the application of IHL by the new African Court of Justice and Human and Peoples’ Rights, essentially through its International Criminal Law Section.
