Critical Roles of Co-doped g-C3N4/Bi2WO6 in photocatalytic removal of organic pollutants and treating oil field wastewater in EC-MFC
Authors: Liu Lifen , Duan Yukuan , Wang Chen , Yang Shilong
Published: May 2023

The synergy activity of the heterojunctions photocatalyst can be
improved further by including the surface plasmon resonance of single
metal atoms. For this aim, a simple calcination and hydrothermal method
was used to dope single atom Co on top of the Z-type 10 wt%
g-CN/BiWO
heterojunctions which we had tested previously. The optimal Co doping
was determined at 0.2 wt% Co/10 wt%
g-CN/BiWO,
that it most efficiently degraded (100 mg/L) RhB under visible light
irradiation (99.7% in 30 min, kinetic rate constant 0.182 min
). This single-atom doped catalysts
(Co/g-CN/BiWO)
should be most favorably used in treating practical wastewater in EC
(electro-chemical)-MFC (microbial fuel cell) system. Its remarkable
performance was recorded (96% COD removal and 92.8% TOC removal). The
reactive oxidizing species include h,
O,
·O, e, and ·OH,
they act together leading to the rapid degradation of pollutants. The
developed Co-doped ternary catalyst has promising application prospects
in pollution control in real world wastewater treatment.
Time-course analysis of cognitive evaluation in aesthetic appreciation
Authors: Bairisal Sunny , Sharma Greeshma , Kujur Abhijeet , Kumar Jyoti
Published: May 2023

Aesthetic appreciation is a complex process that needs a cognitive
explanation for understanding perceivers’ neural processes while
experiencing beauty. The challenge in studying aesthetics lies in
integrating neural activity dynamics with source localization to
establish a neurophysiological framework of aesthetics experience. This
study examines the neural mechanisms that govern aesthetic appreciation
of static images and compares the mechanisms involved in the
appreciation of images rated as beautiful and not beautiful by
participants. In the study, participants rated a series of images on an
aesthetic scale while their neural activity was recorded. The Leders’
model (2004) was used as a theoretical framework. Results showed that
beautiful images elicited higher cognitive affordance compared to not
beautiful images during the early stage of cognition. The analysis of
ERP waveforms revealed greater perceptual processing for not beautiful
compared to beautiful images. Source localization exhibited activation
of the dorsal stream followed by the ventral stream irrespective of the
aesthetic content of an image. Aesthetic appreciation of not beautiful
images engaged the ventrodorsal stream and local processing, which
resulted in a slower Response Time (RT). Evaluative categorization
utilized attentional load allocation in frontal and central regions,
which was higher in beautiful images. It implies that cognitive
evaluation for categorizing higher aesthetic value requires more
integrative neural processing compared to categorizing lower aesthetic
value. These results suggest that the cognitive processes involved in
aesthetic appreciation differ depending on the content of the stimuli
and occur in distinct time frames.
Medical Laboratory Technicians job satisfaction in Generation X, Y and Z: Findings from an online survey in Austria
Authors: Latzke Markus , Schmidt Diana
Published: May 2023

Medical laboratory technicians (MLTs) play an essential role in
healthcare and the profession has to deal increasingly with staff
shortage. Consequently, retention becomes a crucial issue. So far little
attention has been paid to generational differences in factors regarding
job satisfactions of MLTs and comparatively few studies in general have
included the youngest cohort of Generation Z. The aim of this study was
to analyze aspects of MLTs job satisfaction from a generational
perspective and to identify potential for improvement responding to the
different generations. A cross sectional online survey study design was
used. A total of 382 MLTs completed the online survey of which 371 were
assigned to one of the three generational cohorts. The analysis focused
on the satisfaction with several aspects of job satisfaction, the gap
between the relevance and realization if these aspects and the
influencing factors for job satisfaction according to the respective
generation. The results showed that recognition represents the most
important influencing factor for job satisfaction, but other aspects are
mainly relevant for one of the three generations, such as relationships
for Generation X, meaningful contribution for Generation Y and income
for Generation Z. Employers and professional associations can draw on
these findings to positively influence job satisfaction, to support this
essential healthcare workforce.
The potential of extracellular vesicle lipid profiling in Alzheimer's disease.
Authors: Su Huaqi , Masters Colin , Bush Ashley , Barnham Kevin , Reid Gavin , Vella Laura
Published: May 2023

Over the past two decades, there has been increasing research into the
molecular composition and function of small extracellular vesicles in
the central nervous system. This is due in part to the recognition that
small extracellular vesicles likely contribute to the pathogenesis of
neurological diseases such as Alzheimer’s disease, but also an
understanding that small extracellular vesicles are a source of
potential biomarkers. Small extracellular vesicles carry specific cargo
that reflects their biogenesis and cellular origins, including protein,
RNA and lipid. While the protein and RNA content of small extracellular
vesicles in the central nervous system diseases and have been studied
extensively, our understanding of the lipidome of small extracellular
vesicles in the central nervous system is still in its infancy. Lipids
play a significant role in maintaining central nervous system structure
and function, and the dysregulation of lipid metabolism is known to
occur in many neurological disorders, including Alzheimer’s disease.
Here we review what is currently known about lipid dyshomeostasis in
Alzheimer’s disease. We propose that small extracellular vesicle lipids
may provide insight into the pathophysiology and progression of
Alzheimer’s disease and other neurological disorders, and, in the future
perhaps, aid in disease monitoring and detection.

Authors: Gao Peiling , Wu Wei , Chai Hongxing , Gao Penghao , Zhang Xue , Li Mengzhao , Guo Xianglin , Lv Qingxin
Published: May 2023

To investigate water-saving and yield-improving solutions suitable for
saline soils in the Yellow River Delta region, this study was conducted
to investigate the effects of biochar addition on water-salt transport
and winter wheat growth in saline soils under brackish water irrigation
conditions through outdoor pot experiments using local moderately saline
soils. Three irrigation water mineralization levels (0, 2, 4 g·L
) were used with two types of biochar (wheat straw
biochar and corn straw biochar) and four additions (0, 5, 10, 20 t·ha
), with 21 treatments, each replicated three times.
The results showed that both irrigation with brackish water and biochar
application increased soil water content. Irrigation with brackish water
increased soil salinity and intensified soil salinization, while
application of biochar reduced soil salinity and salinization. 2 g·L
brackish water promoted the initial growth of
winter wheat, but led to yield reduction, while application of biochar
promoted the growth of winter wheat and increased yield, with 10 t·ha
YC having better effect. In conclusion, irrigation
with 2 g·L brackish water and application of 10
t·ha YC is a more effective solution for saline
land improvement in this region.
Heterogeneity and quantifying freshly isolated mesenchymal stem cells
Authors: Maličev Elvira , Jazbec Katerina
Published: May 2023

Mesenchymal stem cells (MSCs) are of great interest in cell therapies
due to their immunomodulatory properties and other effects they have on
recipients after autologous or allogeneic transplantation. In the
majority of clinical applications, a high number of MSCs is required;
for this reason, isolated MSCs have to be expanded in the cell culture
until the desired number is reached. Determining the MSC count from
different tissue origins preceding cell expansion is not widely
implemented. Phenotyping using flow cytometry and MSCs enumeration is
usually performed only during or after their expansion. Counting freshly
isolated cells is challenging due to their rareness and heterogeneity.
Heterogeneity is noticeable among donors, tissues, and cell
subpopulations. The identification of MSCs from different tissues is
also complex because there is no consensus on the uniform cell surface
marker panel. There are also differences in the concentration of cells
which may be influenced by donor age, health status, isolation methods,
and various other factors. As MSC applicability is continuously growing
and developing, there is a need to implement and standardise counting
methods for freshly isolated MSCs. With the introduction of a uniform
procedure to count MSCs right after tissue harvest, we could predict the
number of passages needed for cell expansion and reduce overall cell
manufacturing costs. For new methodologies, where uncultured cells are
used in therapy with what are referred to as one-step procedures,
determining the number of freshly isolated MSCs is even more important

This study introduces a methodology to estimate the economy-specific task content of occupations across economies at different income levels. The results show that occupations in low- and middle-income economies are more routine-intensive than in high-income economies and the gap continues to widen. Investment in skills, technology use, and participation in global value chains are key factors for work content and productivity to converge with those in high-income economies.
Access to Pensions, Old-Age Support, and Child Investment in the People’s Republic of China
Authors: Shan Xiaoyue , Park Albert
Published: May 2023

This study shows that the new pension program in the People’s Republic of China can fundamentally alter the traditional support system between generations. While it lessens the role of working-age adults to provide support to their old-age parents, it may also have an impact on the educational investment of parents in their children depending on their gender. Along with the new pension program, policies to reduce school dropout and to support children who receive less parental investment may mitigate the unintended adverse impact.
Assessment of equivalent methods effectiveness used for honeycomb plate structure
Authors: Mankour Abdeljelil , Smahat Amine
Published: May 2023

Honeycomb plates are commonly used in aerospace structures for their lightweight and rigidity characteristics. However, for modeling honeycomb structure many equivalent methods are established to represent the behavior of detailed model. In the present paper, we focus on the equivalent methods precision compared to the miso-scale model. Therefore, we compare two equivalent assumptions regarding the detailed design of a honeycomb plate (miso-scale). Then, we perform modal analysis and microvibration assessments to verify the effectiveness of methods accuracy regarding modes values and microvibration transmissibility. It can be noticed that each method has the advantage to be a candidate to represent the honeycomb plate behavior due to the lower error percentage. The sandwich plate theory gives minimal difference error for both modal analysis and the measurement of disturbance transmissibility from the reaction wheel to the structures. Hence, the sandwich theory is more or less accurate for representing a detailed model for structural analysis of honeycomb plates.

Published: May 2023

Tradisi syawalan bagi masyarakat muslim di Jawa, salah satu tradisi yang biasa dilaksanakan setiap tanggal 7 Syawal, atau seminggu setelah hari raya Idulfitri. Syawalan ini bisa disebut sebagai bodo kupat, istilah yang dipakai oleh masyarakat untuk menyebut tradisi syawalan, sebab hidangan yang disajikan adalah ketupat, tetapi tidak semua daerah menyajikan ketupat dalam tradisi syawalan. Di Kota Pekalongan dikenal dengan bodo lopis sebab hidangan yang disajikan adalah lopis. Lopis adalah kue yang dibuat dari olahan beras ketan yang dibungkus dengan daun pisang berbentuk bulat lonjong, maupun segitiga dan dinikmati dengan baluran parutan kelapa dan gula merah. Sejarah kue lopis merupakan makanan peranakan Cina yang berakulturasi dengan budaya Cina, Jawa, dan Arab. Pemilihan sajian kue lopis sebagai hidangan utama dalam tradisi syawalan di Desa Krapyak mempunyai makna dan filosofi sendiri sehingga dalam tulisan ini penulis tertarik untuk mengkaji makna fungsi dan nilai dari tradisi bodo lopis di Desa Krapyak, Kota Pekalongan dengan menggunakan pendekatan semiotika yang menggunakan metode deskriptif kualitatif. Dari hasil analisis dapat disimpulkan bahwa tradisi bodo lopis mempunyai makna persaudaraan yang erat dengan menjalin silaturahmi antar masyarakat kembali suci setelah melaksanakan ibadah puasa Ramadhan, dilanjutkan dengan puasa syawal yang disimbolkan kue lopis sebagai sajian utama.

Published: May 2023

The modeling of both the synchronous generator and induction motor which is represented by the rotor reference frame was studied where the modeling was established using MATLAB /SIMULINK software package for an isolated synchronous generator direct-on-line with different sized induction motors; 20, 50, and 100 Hp, at manually adjusted excitation voltage values which were maintained constant at 3.35, 4.55, and 6.21 V, respectively. The purpose of this work is to study the impact of a sudden increase in the load torque; from 0 to 150 % with an increase of 25 %, of full load torque was studied at a constant motor speed of 188.49 rad sec-1. On the other hand, the impact of a sudden decrease in the rotor speed by about 20 % from its rated value; from 188.49 to 150.79 rad sec-1 was also studied at full load torque of the same different-sized induction motors. These values were manually recorded and response variables of the generator including terminal voltage, current, output power, electromagnetic torque, and load angle were determined and represented as a function of time. The results illustrated the Changes in the terminal voltage, the current, the output power, the electromagnetic torque, and the load angle as parameters of a synchronous generator for different-sized induction motors.
Analysis of Defense Mechanisms in Hawkins’ The Girl on the Train
Authors: Shrivastwa Bimal Kishore
Published: May 2023

This research paper seeks to examine the psychic behaviors and the defense strategies used by the leading character of Paula Hawkins’ novel, The Girl on the Train, Tom to avoid his emotional injuries. In order to explore how Tom uses defense mechanisms for releasing traumatic tensions and protect self-image, the research tool used for the investigation is Crammer’s concept of defense mechanism instruments such as such as repression, reaction formation, and denial. The uses of various types of defense mechanisms by Tom mainly repression, reaction formation and denial help him live his life with an ‘illusion of being clean’ despite being a cheater, liar and murderer. The research not only corresponds to the hidden incidents that Tom emerges on but also other factors supporting to the use of defense mechanism. It digs out the reasons Tom blames or neglects others and lives in the illusionary world of ‘being clean’ that justifies the flaws in his behavior. The finding is that the central character, Tom is suffering from ego split and he is trying to get out from tensions and anxiety. It is expected that this paper stands as a reference to the scholars intending to research Hawkins further.

Ungewöhnlich ist der Ort für unser Interview, atemberaubend und in rund 80 Metern Höhe, unter uns der Rhein, der Hauptbahnhof von Köln, die Hohenzollernbrücke und die modernen Büro-Hochhäuser der Stadt. Vor uns die beiden mächtigen schwarzen Türme des Kölner Doms. Wir stehen auf der Plattform des Vierungsturms, der auf dem Dach des Doms „sitzt“. „Hier oben spürt man einmal mehr, was für ein gewaltiges Werk der Dom ist“, sagt Dombaumeister Peter Füssenich, „er ist nicht nur ein Gebäude. Es ist ein Universum.“ Wer immer in den vergangenen siebenhundert Jahren am Dom arbeitete, wusste, dass dieses Gebäude zu seinen Lebzeiten nie fertig wird. Dies gilt auch für Peter Füssenich, der neunzehnte in einer langen Reihe von Dombaumeistern, die bis ins Mittelalter reicht.

Warum Sie sich in Projekten mehr um Misserfolgsfaktoren kümmern sollten
Authors: Erne Rainer , Hüsselmann Claus , Langhardt Stefanie

Die erfolgreiche Zielerreichung von Projekten hängt in erheblichem Ausmaß von der Vermeidung von Verschwendung ab. Diese findet allerdings oftmals unter dem Radar der Projektarbeit statt, so dass im Streben danach, Projekte erfolgreich zu machen, eher unterschwellige Faktoren, wie bspw. Warten auf Zulieferungen oder Suchen nach Informationen, außer Acht gelassen werden. Solche Mitterfolgsfaktoren werden im Lean Management als Verschwendung bezeichnet, da sie keinen Beitrag zur Wertschöpfung leisten. Mit Lean Project Management liegt ein konzeptioneller Ansatz vor, mit dem Verschwendung identifiziert und mit Hilfe bewährter Prinzipien und Praktiken vermieden werden kann. In dem Beitrag werden in einem ersten Teil anhand zweier Fallbeispiele grundsätzliche Hinweise auf Verschwendung in Projekten gezeigt. In einem zweiten Teil wird ein Ansatz vorgestellt, mit dem Verschwendung systematisch identifiziert und eliminiert werden kann. Anhand des „Project Management Wast Index“ ist eine Analyse über die hauptsächlichen Verschwendungsarten in Projekten möglich und damit der Hebel für die Vermeidung bestimmter Störfaktoren gefunden.

Can gadget manage the classroom?

The Pandemic is switching the teaching and learning process, which usually organizes face-to-face into a virtual setting. This condition initiated research to determine how the gadgets influence students' learning motivation and whether gadgets can manage face-to-face or not. The respondents were thirty-six addicted and seventy-four non-addicted gadgets of junior and senior high school students from five districts in North Kalimantan. The data collected was a closed questioner, and an interview was conducted virtually. The results showed that the gadget motivates the students since it enables all the respondents to practically access the material and minimizes respondents' anxiety in expressing the ideas. Discouragingly, the gadget could not take place in the face-to-face learning setting. Non-addicted and most addicted respondents claim that face-to-face learning builds direct interaction between peers and teachers, which cannot be found in online classes. Furthermore, the e-learning class supplies unmanageable assignments with the defective explained material. The class often holds asynchronously and gives fewer responses once the students ask for a detailed explanation. Furthermore, once the synchronous class is hosted, the internet connection distracts the class.
Quo Vadis Brand Love? Role of Cognition-Affection-Behavior Model for Local Coffee Shops in Indonesia
Authors: Farahdiba Dea
Published: May 2023

This study aims to identify the structural relationship between image, experience, love, trust, and brand loyalty for branded local coffee shops using the cognitive-affective-behavior (C-AB) model. One hundred thirty-five respondents participated in this study, and data analysis was performed using the SmartPLS statistical tool with the PLS-SEM method. It was found that brand image and experience had a significantly positive relationship with brand love and trust. Brand love and brand trust also have a significant positive relationship with brand loyalty, according to the assessment of Indonesian people on their favorite local coffee shop brands. This study contributes to the literature that the C-A-B model can explain the factors that form brand loyalty in the local coffee shop industry. In practice, brand love and brand trust owned by local communities form brand loyalty relationships in local products. This study also shows the mediating effect of brand love and brand trust for branded local coffee shops. Brand Love indirectly mediates the relationship between Brand Image and Brand Loyalty, but Brand Trust does not directly mediate the relationship between Brand Experience and Brand Loyalty. This study's main limitation is using the brand love mark only for brand love. The dimension of the brand love mark as Brand Respect can be included in future research.

Published: May 2023

Numerous known risk factors for atrial fibrillation (AF) exist, but few studies have investigated the link between gastrointestinal and liver disorders. Through a variety of pathways, hepatic and gastrointestinal conditions can increase the risk of both prevalent and incident AF. According to numerous studies, liver dysfunction plays a significant role in the pathogenesis of atrial fibrillation. So, this review article aimed to give an overview of how liver function tests played role in the AF. Albumin, alkaline phosphatase, alanine transaminase, aspartate aminotransferase, gamma-glutamyl transferase, serum bilirubin, and prothrombin time were highlighted in the pathogenesis of AF. However, the 5’-nucleotidase test, alpha-fetoprotein test, mitochondrial antibodies test and more, and liver functions test need to find their pathogenesis in AF. The exact mechanism of action of the liver panel was not reported in the pathogenesis of AF. To control the major liver diseases in AF patients, the therapeutic management of liver function tests is required.
Autobiografías y elección de carrera de educadores en Ciencias Naturales
Authors: Luzuriaga Mariana , Podestá María Eugenia , Furman Melina
Published: May 2023

Las autobiografías docentes son un elemento clave para comprender la elección de carrera. Mediante un análisis temático de contenido se analizaron las experiencias formativas de 70 docentes argentinos de Ciencias Naturales que cursan un posgrado universitario. De las experiencias formativas relatadas la mayoría (43%) se dio en la escuela secundaria; destaca que de dicho porcentaje 40% fueron calificadas como “negativas”. Los resultados revelaron tres tipos de referentes: docentes Faro, quienes despertaron interés por las ciencias o la enseñanza; Inspiradores, modelos a seguir por su forma de enseñar, y Antimodelos, aquellos a los que no se quiere imitar; y, por otro lado, evidenciaron la importancia del nivel secundario como etapa definitoria en la orientación profesional, así como la necesidad de que existan buenos modelos que fomenten la elección de la docencia, en particular de disciplinas con escasez de profesores –como lo son las científicas.
