Authors: Milivojevic Jasminka , Radivojevic Dragan , Milosavljevic Dragica , Maksimovic Vuk , Dragisic-Maksimovic Jelena
Published: July 2023

The aim of this study was to compare newly released June-bearing strawberry
cultivars (?Quicky?, ?Sandra?, ?Lofty?, ?Nadja? and ?Aprica?) in terms of
their phenology, vegetative growth, productivity and fruit quality to
identify their potential for wider cultivation. A field study was conducted
in a strawberry plantation established in July 2020 in double rows on beds
covered with black polyethylene foil (Sid, Serbia). The cultivars were
evaluated in 2021-2022 for their flowering and ripening time, productivity,
plant growth, biometrical and nutritional fruit traits (soluble solids
content - SSC, total acids - TAs, vitamin C, total anthocyanins - TACY,
total phenolics - TPC and total antioxidant capacity - TAC). The cultivar
?Quicky? started to ripen earliest, while ?Aprica? was the latest in both
experimental years. The number of branch crowns per plant was significantly
higher in ?Sandra? and ?Lofty?, whereby ?Sandra? had also the highest number
of leaves per rosette (41.5) in comparison with the other tested cultivars.
The cultivar ?Aprica? was superior in terms of productivity (1061 g/plant
and 4.67 kg/m2), fruit weight (29.9 g) and fruit shape index (1.15).
Contrary to this, ?Nadja? was the least productive cultivar (608 g/plant and
2.68 kg/m2). The cultivars ?Lofty? and ?Sandra? showed the highest SSC
values and were also characterized by a considerably high level of TPC (1.29
mg GAE eq g-1 FW) and TACY (24.4 mg pg-3-g eq 100 g-1 FW), respectively.
Variability among the tested cultivars could serve as an important criterion
for the selection of new high-performing cultivars for a given growing
region.
Energy management and dc bus voltage stabilization in a HRES based DC microgrid using HESS
Authors: Rajput Amit , Lather Jagdeep
Published: July 2023

This paper proposes a control strategy with stability analysis for a hybrid energy storage system (HESS) in a DC microgrid (DCMG) consisting of hybrid renewable energy sources (HRESs). The proposed control strategy effectively regulates DC bus voltage (DBV), maintains a balance in demand-generation and improves the power quality by flattening the intermittency in PV generation. The proposed configuration harnesses the advantage of both battery energy storage system (BESS) and supercapacitor (SC) energy storage system (SCESS) in the HESS through their effective utilization as per their power and energy densities. A filtration-based control (FBC) has been proposed using PI controllers to generate the reference signals as per inherent internal characteristics of BESS and SCESS. The efficacy of the proposed configuration is analyzed through simulations using Simscape? module of MATLAB? software. The results are further validated using the FPGA-based real-time simulator Opal-RT.
Influence of rare earth oxide and graphite on the mechanical and tribological properties of Fe/Cu based sintered friction materials
Authors: Kasi Rajesh , Ramalingam Vaira , Myilsamy Govindaraju , Kumar Samuel
Published: July 2023

Fe/Cu-based sintered friction materials are proven potential materials for heavy-duty applications. The current research explores the influence of rare earth oxide (Nd2O3) and graphite on the tribological characteristics of Fe/Cu-based friction materials. The constituents present in the friction material are Fe, Cu, Cg (1%, 3%, 5%, 7%), BaSO4, and Nd2O3 (5%). Optical microscopy and elemental mapping studies reveal the homogeneous distribution of elements in the matrix. Sintered density of the specimens showed a maximum of 70% of the theoretical density measured by Archimedes' principle. XRD analysis shows no new phase formation in all the sintered specimens. A peak microhardness result of 96 HV is obtained in specimen NG-01. The pin?on?disc tribotests are performed at an axial load of 50 N at a sliding velocity of 5.5 m/s. Specimen NG-03 with 3% graphite exhibited an optimum wear rate with a friction coefficient of 0.45. The surface morphology and elemental composition of the worn specimens are investigated. The morphological features inferred that the wear mechanism is predominantly mixed abrasive and adhesive.
153-OR: Genetically Supported Therapeutic Targets for Coronary Artery Disease in Diabetes—Evidence from Proteome-Wide Mendelian Randomization
Authors: HUANG CHUIGUO , SHI MAI , YU GECHANG , CHAN JULIANA C. , MA RONALD C.
Published: July 2023

Coronary artery disease (CAD) remains a major burden in people with diabetes. Genome-wide association studies (GWASs) have identified multiple genetic loci, yet most have yet to translate to clinical applications. The aim of this study was to leverage on genetic data to identify novel drug targets for CAD in diabetes. We applied Mendelian randomization (MR) to investigate the causal association of 1677 plasma proteins from 6 large GWASs, and a recently published GWAS of 15,666 individuals with diabetes (including 3968 CAD cases and 11698 controls). 5 of the 6 proteomic studies were selected as discovery MR analysis, and the remaining one as replication MR to validate the top findings. We employed sensitivity analyses, Bayesian colocalization and transcriptome-wide association study (TWAS) to test the validity of MR assumptions and meanwhile prioritized candidates of drug targets using multi-omics layers. We further integrated phenome-wide MR using the summary data from UK Biobank (N≤408 961) studies and clinical evidence based on DrugBank database to detect potential side effects associated with hypothetical therapeutic agents for CAD in diabetes and prioritize them. Our primary discovery MR analysis identified 4 prioritized proteins (F5, LPA, NPPB and TNFRSF11B) with both MR and colocalization evidence. NPPB and TNFRSF11B could be verified by replication MR analysis. Multi-tissue TWAS analysis revealed all 4 targets whose imputed expression was associated with the outcome. No adverse side effects were found for LPA via phenome-wide MR. By combining the putative causal MR signals with clinical evidence, we suggested these 4 drug repurposing opportunities for the treatment of CAD with diabetes that warranted further investigation. In summary, we prioritized 4 potential drug targets for CAD in diabetes. In particular, LPA might represent a promising target for the treatment of CAD in diabetes, with no predicted adverse side effects.

Authors: Khalel Mohammed Hazim , Hamza Ali Fuad , Khaled Firas
Published: July 2023

What is meant by water harvesting is the process of collecting and storing surface runoff water resulting from precipitation to benefit from it for agricultural purposes, feeding underground storage, and providing drinking water for humans and animals. For the basin, especially evaporation, where the number of hours of the solar surface was recorded in two Kirkuk stations (11) hours/day, respectively, and it was recorded in Chamchamal station at about (12) hours/day, while it decreases during the winter months, as it reaches about (5) in Chamchamal station, respectively, while in Kirkuk station reached (6) hours/day, respectively. The highest monthly rates were recorded during the winter months (December) by (66.4, and 66.7%) for both stations (Chemchamal-Kirkuk), respectively. While its lowest monthly rates were recorded during the summer months (July and August), when it reached (24.2%), which can predict the presence of saturated soil, which reduces filtration and leakage after rain falls and generates surface runoff, which can be harvested and utilized from the water. For both stations, they are spatially and temporally dissimilar, as the highest average of their monthly totals was recorded during the winter seasons in Chamchamal station in January and February to (92.9 mm) respectively, then it decreased relatively during December as recorded (90.1 mm). The annual rainfall was recorded in both stations (Chemchamal-Kirkuk) (502.3, 337.7 mm). It is clear from the foregoing that the plant has an important role in the presence of organic matter in the soil, which increases the seepage of falling rainwater and does not generate surface runoff. Therefore, the areas that are characterized by the presence of vegetation can be exploited by applying the harvesting methods designated for such areas that are characterized by water leakage into the ground, and therefore the soil is radiant with moisture, which can be cultivated directly, especially by applying the technology of mountain terraces that works to impede water and increase its seepage into the soil layer, especially These areas are characterized by their height and exposure to soil erosion after heavy rains.

Authors: Merinda Lestandy  , Abdurrahim
Published: July 2023

Emotion is an element that can influence human behavior, which in turn influences a decision. Human emotion detection is useful in many areas, including the social environment and product quality. To evaluate and categorize emotions derived from text, a method is required. As a result, the CNN-BiLSTM model, a classification method, aids in the analysis of the text's emotional content. A word weighting technique employing word2vec as a word weighting will help the model. The CNN-BiLSTM model with Word2vec as a pre-trained model is being used in this study to find the findings with the highest accuracy. The information is split into two groups: training and testing, and it is categorized into six categories according to how each emotion manifests itself: surprise, sadness, rage, fear, love, and joy. The best outcome from the CNN-BiLSTM model's accuracy of emotion classification is 92.85%.

The impact of the industrial revolution 4.0 developments with physical and internet cyber systems in the education sector is the development of computer-based teaching which then propagates to the development of online learning and the use of e-learning media. With a combined system, distance learning occurs in a learning management system with web-based assistance platforms and social media which is the result of the development of Industry 4.0 during the 21st century. The main objective of this research is to analyze and compare student perceptions in implementing eight platforms of implementing an online-based Learning Management System at the tertiary level. Then, this study links students' perceptions in implementing online-based learning management with reference to three aspects of assessment; teaching and learning aspects, lecturer competency aspects, and infrastructure aspects. A quantitative approach with a survey design has been chosen. Sampling technique was purposive sampling and involved 147 respondents. The results concluded that the Zoom, Google Classroom and Whatsapp platforms were the most frequently used distance learning media and were also liked by students. Currently, not many lecturers use Moodle because there is not enough time to learn how to use Moodle and prepare all the resources to design the desired learning, while there are many alternative platforms that are easier to learn and use in a short time. The survey on the three aspects of daring learning has been agreed in detail and the results provide positive conclusions regarding the implementation of online-based learning in the past 4 years.

Authors: Leba Seli Marlina Radja , Temaja I Gede Bagus Wisnu Bayu
Published: July 2023

The use of ICT in teaching develops more important in present times because teachers also have to be able to keep up with the technological knowledge of their students. This study aims to analyze the pre-service teachers’ use of ICT in their classrooms during the practice teaching experience. This study employed both quantitative and qualitative data collection tools. The data were obtained from 86 pre-service teachers at senior high school and Junior High School. The data were collected qualitatively through observation and semi-structured interviews and quantitatively using a questionnaire. The qualitative results were mapped in tabular form. The researchers analyzed qualitatively to explain why pre-service teachers do not use ICT tools. The data were also made in tabular form and were described. The results showed that the practicum schools were not very rich in the technological devices offered to the pre-service teachers for their EFL classes. The pre-service teachers were not helped by ICT available to them in their teaching practice at a not satisfying level. Insufficient training, lack of basic facilities in the practicum schools, and pre-service teachers’ selections were the main reasons for teachers to utilize ICT in teaching practice. The study’s findings discovered a mismatch between teacher training programs and real-world classrooms in ICT integration in EFL instruction. Pedagogical inferences of the study consist of the need for better integration of ICT in EFL teacher training and a more vital link between the schools and the university.

Las condiciones económicas de los estudiantes mexicanos determinan en gran medida las posibilidades de realizar sus estudios universitarios. Especialmente los alumnos provenientes de municipios con mayores índices de pobreza son los que tienen menos oportunidades de cursar estudios superiores. Dado que la pobreza en México se estima entre el 34.9% y el 36.2%, es de gran importancia contar con una estimación sólida de los gastos necesarios para cubrir los bienes y servicios requeridos en la educación superior. Esto permitirá que los futuros estudiantes universitarios tengan una comprensión más clara y precisa de los gastos que deberán afrontar durante su vida universitaria.

En este estudio de caso realizado con los alumnos de licenciaturas del Centro Universitario UAEM Temascaltepec, se identificaron los bienes y servicios que los estudiantes requieren. Como resultado, se encontró que los estudiantes destinan en promedio $8,607.76 pesos mexicanos al mes para cubrir estas necesidades. El análisis estadístico (ANOVA) reveló que los gastos realizados por los alumnos son estadísticamente iguales (p>0.05) en las diferentes licenciaturas. Sin embargo, se encontraron diferencias significativas (p<0.05) en los gastos realizados por los estudiantes provenientes de los municipios analizados. La comparación múltiple de medias mostró que los alumnos provenientes del municipio de Valle de Bravo incurren en mayores gastos, con un monto medio de $15,206.77 pesos mexicanos.

Esta información será útil para los futuros estudiantes universitarios, ya que les permitirá planificar un ahorro y tomar acciones que les permitan cubrir los gastos necesarios, facilitando así su ingreso y culminación de los estudios.
Rethinking Offa’s Dyke as a Hydraulic Frontier Work
Authors: Williams Howard
Published: July 2023

Building upon a fresh interpretation of Wat’s Dyke as a component of an early medieval hydraulic frontier zone rather than primarily serving as a symbol of power, a fixed territorial border or a military stop-line (Williams 2021), here, I refine and apply this approach to its longer and better-known neighbour: Offa’s Dyke.  This linear earthwork’s placement, alignments and landscape context are evaluated afresh using a simple but original comparative mapping methodology. First, on the local level, I show that Offa’s Dyke was carefully and strategically positioned to connect, overlook and block a range of watercourses and wetlands at key transverse and parallel crossing points, thus observing and choreographing mobility on multiple axes. Second, I address the regional scale, showing how Offa’s Dyke interacted with, and controlled, biaxial movement through and between water catchments parallel and transverse to the monument’s principal alignments. Both these arguments inform how the Dyke might have operated on the supra-regional scale, ‘from sea to sea’ and also ‘across the sea’, by controlling the estuarine and maritime zones of the Dee Estuary in the north and the Wye/Severn confluence to the south. Integrating military, territorial, socio-economic and ideological functionality and significance, Offa’s Dyke, like its shorter neighbour Wat’s Dyke (in an as-yet uncertain relationship), configured mobilities over land and water via its hydraulic dimensions and interactions. Together, the monuments can be reconsidered as elements of a multi-functional hydraulic frontier zone constructed by one or more rulers of the middle Anglo-Saxon kingdom of Mercia and operative both in times of peace and conflict.
Evaluating the Early Medieval Portable Antiquities Scheme Data for the Welsh Marches
Authors: Clarke Pauline
Published: July 2023

This article explores the early medieval data from the Portable Antiquities Scheme (PAS) from across two countries and several counties to ascertain what this can reveal about boundary formation, including the construction and use of Offa’s and Wat’s Dykes, during the seventh to ninth centuries AD. Surveying the borderlands which become Welsh Marcher lordships in the Later Middle Ages, the study disproves the popular assumption that the region is devoid of early medieval material culture. Instead, by examining what material culture is known through the PAS it may be possible to demonstrate activity here from the beginning of the ingress into Britain of Anglo-Saxon and later Scandinavian culture.

The regularities of obtaining polylactide film composite materials with simultaneous silver nanoparticles formation were researched. The influence of the nature of polylactide and its structure (amorphous and amorphous-crystalline), of the glycerin plasticizer on the solvent evaporationkinetics  was determined. To give polylactide composites fungicidal properties, the silver reduction reaction by the interaction of argentum salts with polyvinylpyrrolidone was applied. A main technological scheme for obtaining films based on polylactide with fungicidal properties is proposed. Above mentioned provides effective practical usage of the films as packaging materials for food products and medicines.
A Philosophy of Beauty
Authors: Gill Michael B.
Published: July 2023

At the turn of the eighteenth century, Anthony Ashley Cooper, the third Earl of Shaftesbury (1671–1713), developed the first comprehensive philosophy of beauty to be written in English. It revolutionized Western philosophy. This book presents an engaging account of how Shaftesbury's thought profoundly shaped modern ideas of nature, religion, morality, and art—and why, despite its long neglect, it remains compelling today. Before Shaftesbury's magnum opus, Charactersticks of Men, Manners, Opinions, Times (1711), it was common to see wilderness as ugly, to associate religion with fear and morality with unpleasant restriction, and to dismiss art as trivial or even corrupting. But Shaftesbury argued that nature, religion, virtue, and art can all be truly beautiful, and that cherishing and cultivating beauty is what makes life worth living. And, as the book shows, this view had a huge impact on the development of natural religion, moral sense theory, aesthetics, and environmentalism. Combining captivating historical details and flashes of humor, the book not only rediscovers and illuminates a fascinating philosopher but also offers an inspiring reflection about the role beauty can play in our lives.
