Cherry tomato (Solanum lycopersicum L,. var. cerasiforme Mill.) is small fruits with a bright red color resembling a cherry and having an excellent taste, sweet and juicy ambience. So far, no cherry tomato variety was registered in Ethiopia. Consequently, six genotypes were imported from National Institute of Horticulture and Herbal Sciences (NIHHS), Rural Development Administration (RDA) Republic of Korea, and field experiment was conducted in RCBD with three replications at six Ethiopian testing sites, with irrigation, during off-seasons of 2021 and 2022 to identify high yielding, well adapted and good quality varieties. The overall analysis of variance across locations and years showed non-significant difference among the genotypes for marketable and total yields. But separate analysis for each site has revealed significant differences among genotypes at Melkassa, Koka, Adami- Tulu and Fogera, unlike that of Kulumsa and Woramit. There were significant differences (P < 0.05) among these genotypes for fruit numbers per plant, average fruit weight, fruits per cluster, plant height, skin thickness, juice volume and total soluble solid. Wonhong No.3 gave higher marketable (24.49 t/ha) and total (26.19 t/ha) yields, and generally Wonhong Nos.3 and 5 had higher yields and good qualities across these tested locations and years. Hence, Wonhong No.3 (designated as Jorgie-1) was registered for its higher yield, non-cracking, good TSS and color, while Wonhong No.5 (renamed as Jorgie-2) was preferred for its smaller fruit size, reasonable yield and quality (TSS, color, non-cracking). Hence, both varieties were officially registered in 2023 season for commercial production in different agro-ecologies of Ethiopia, and they are believed to add more economic and nutritional values for the tomato producers and the consumers. They can also support the intensification of tomato cultivation in peri-urban and urban agriculture, where demands and thus government focus are increasingly growing.

This study investigates the strategies that teachers employ when presenting the meaning and form of a novel English word to students with autism spectrum disorder (ASD). This case study observed and interviewed three teachers who taught five ASD students with diverse characteristics and varying language proficiency. Thematic analysis was conducted by integrating a top-down approach, based on the vocabulary teaching strategies commonly used with typically developing students, and a bottom-up approach, based on the emerging data. The results indicate that, similar to their typically developing peers, the meaning and form of the new English word were introduced by connecting to the first language, providing first language definitions, relating to real objects and phenomena, encouraging students’ active participation through elicitation, and conducting oral drills and word spelling. However, unlike typically developing students, the teachers presented English vocabulary to ASD students while making an effort to capture their attention and engagement in the learning process. This study offers suggestions for teachers and recommendations for future research.

The Qi Family Tree Bone Inscription refers to the Xia dynasty king list, and the deciphered bone names match the names of the Xia kings recorded in the classics. First, this bone inscription is authentic according to Sarah Allan and Kuang Yu Chen’s recent study of the engraved strokes of script viewed under microscope. Secondly, this paper introduces the interactive events between Xia Si (夏姒) people and Shang royal people in the Shang bone texts, such as the Shang conquest of the Xia Si, using the Xia people to serve the Shang King affairs, resettling the Xia people north and letting them fight others. This paper specifically interprets the bone scripts of Xia Si to mean that Xia indicates lowland for farming, and Si is the family name of the Xia recorded in the classics. The script for Si (surname) is derived from the image of a silkworm, as the Si are a silkworm totem people. Another decoded script for Xia is a river name, Xia (river) is named after “canal digging and irrigating”. Third, this paper deduces that the Xia people were living in the Jiang Xia (now Jiang Han or Jiang and Han rivers) plains, the Shijiahe site is the ruins of the Xia or Pre-Xia, and a large number of the Shijiahe red pottery figurines for dances were unearthed, which is consistent with the Xia dance and music recorded in the classics. The unearthed jade statues of deities look like silkworm moths, which corresponds to Xia Si being a sericulture tribe. After the Shijiahe culture, the Xia people built a last capital at Panlongcheng (or Panlong City), near the Xia River outlet. Because the classic Poem for the war epic named Shang Hero (殷武) says, “Got there the hero Cheng Tang (達彼殷武), went to conquer Jing Chu in strength (奮伐荊楚, Jing Chu 荊楚is the alternative name of Jiang Xia 江夏).” Another classic Poem for the Shang national epic called Long Growth (長發) says, “The states of Gu and Wei have been conquered (顧韋既伐).” The Gu and Wei are the current Xiangyang 襄陽 and Suixian 隨縣 on the east and west pathways to the Jiang Xia Basin from the Yellow River Basin, based on their ancient names and their sounds being homophonic. After occupying the states of Gu and Wei, the Shang army went south to form a situation of surrounding the Panlongcheng site of the Jiang Xia Plain. Thus, King Jie of Xia gave up the capital and went north to through the Ming Pass (present-day Wusheng Pass 武勝關) to the Huai River Plain of the East People 東夷, and there was the Battle of Ming Tiao in the Ming Pass. Finally, this study introduces an article about the oracle bone script ten classifications or designs, explaining how to decipher a script. The script for names engraved on the bone tablet were deciphered, corresponding to the name of the Xia Emperors in the classics. The meaning of the deciphered characters of the Xia Emperor names is consistent with the deeds of the Xia Emperors recorded in the classics. In the Qi family genealogy, there are inscriptions of the event of an older brother dying and his younger brother assuming the throne, which matches the record in the classics.

As the Fourth Industrial Revolution advances, smart factories have become a new manufacturing paradigm, integrating technologies such as Information and Communication Technology (ICT), the Internet of Things (IoT), Artificial Intelligence (AI), and big data analytics to overcome traditional manufacturing limitations and enhance global competitiveness. This study offers a comprehensive approach by evaluating both technological and economic performance of smart factory Research and Development (R&D) projects, addressing gaps in previous studies that focused narrowly on either aspect. The research combines Latent Dirichlet Allocation (LDA) topic modeling and Data Envelopment Analysis (DEA) to quantitatively compare the efficiency of various topics. This integrated approach not only identifies key research themes but also evaluates how effectively resources are utilized within each theme, supporting strategic decision-making for optimal resource allocation. Additionally, non-parametric statistical tests are applied to detect performance differences between topics, providing insights into areas of comparative advantage. Unlike traditional DEA methods, which face limitations in generalizing results, this study offers a more nuanced analysis by benchmarking efficiency across thematic areas. The findings highlight the superior performance of projects incorporating AI, IoT, and big data, as well as those led by the Ministry of Trade, Industry, and Energy (MOTIE) and small and medium-sized enterprises (SMEs). The regional analysis reveals significant contributions from non-metropolitan areas, emphasizing the need for balanced development. This research provides policymakers and industry leaders with strategic insights, guiding the efficient allocation of R&D resources and fostering the development of smart factories aligned with global trends and national goals.

Iron selenides with high capacity and excellent chemical properties have been considered as outstanding anodes for alkali metal-ion batteries. However, its further development is hindered by sluggish kinetics and fading capacity caused by volume expansion. Herein, a series of FeSe2 nanoparticles (NPs)-encapsulated carbon composites were successfully synthesized by tailoring the amount of Fe species through facile plasma engineering and followed by a simple selenization transformation process. Such a stable structure can effectively mitigate volume changes and accelerate kinetics, leading to excellent electrochemical performance. The optimized electrode ( FeSe2@C2) exhibits outstanding reversible capacity of 853.1 mAh g− 1 after 150 cycles and exceptional rate capacity of 444.9 mAh g− 1 at 5.0 A g− 1 for Li+ storage. In Na+ batteries, it possesses a relatively high capacity of 433.7 mAh g− 1 at 0.1 A g− 1 as well as good cycle stability. The plasma-engineered FeSe2@ C2 composite, which profits from synergistic effect of small FeSe2 NPs and carbon framework with large specific surface area, exhibits remarkable ions/electrons transportation abilities during various kinetic analyses and unveils the energy storage mechanism dominated by surface-mediated capacitive behavior. This novel cost-efficient synthesis strategy might offer valuable guidance for developing transition metal-based composites towards energy storage materials.

Crystalline heptazine carbon nitride (HCN) is an ideal photocatalyst for photocatalytic ammonia synthesis. However, the limited response to visible light has hindered its further development. As a noble metal, Au nanoparticles (NPs) can enhance the light absorption capability of photocatalysts by the surface plasmon resonance (SPR) effect. Therefore, a series of Au NPs-loaded crystalline carbon nitride materials (AH) were prepared for photocatalytic nitrogen fixation. The results showed that the AH displayed significantly improved light absorption and decreased recombination rate of photo-generated carriers owing to the introduction of Au NPs. The optimal 2AH (loaded with 2 wt% Au) sample demonstrated the best photocatalytic performance for ammonia production with a yield of 70.3 μmol g− 1 h− 1, which outperformed that of HCN. This can be attributed to the SPR effect of Au NPs and alkali metal of HCN structure. These findings provide a theoretical basis for studying noble metal-enhanced photocatalytic activity for nitrogen fixation and offer new insights into advances in efficient photocatalysts.

A substantial quantity of discarded tires has inflicted harm on the environment. Microwave pyrolysis of discarded tires emerges as an efficient and environmentally friendly method for their recycling. This research innovatively utilizes the characteristics of microwave rapid and selective heating to pyrolyze waste tires into porous graphene under the catalysis of KOH etching. Moreover, this study comprehensively investigates the dielectric characteristics and heating behavior of waste tires and different proportions of waste tire–KOH mixtures. It validates the preparation of graphene through KOH-catalyzed microwave pyrolysis of waste tires, tracking morphological and structural changes under varying temperature conditions. The results indicate that optimal dielectric performance of the material is achieved at an apparent density of 0.68 g/cm3 at room temperature. As the temperature increases, the dielectric constant gradually rises, particularly reaching a notable increase around 700 °C, and then stabilizes around 750 °C. Additionally, the study investigates the penetration depth and reflection loss of mixtures with different proportions, revealing the waste tire–KOH mass ratio of 1:2 demonstrates favorable dielectric properties. This research highlights the impressive microwave responsiveness of the waste tire–KOH mixture, Upon the addition of KOH, the mixed material exhibits an augmented dielectric constant and relative dielectric constant, supporting the viability of KOH-catalyzed microwave pyrolysis for producing porous graphene from waste tires. This method is expected to provide a new method for the valuable reuse of waste tires and a technology for large-scale, efficient and environmentally friendly production of graphene.

With the development of photocatalytic hydrogen production technology, the effective transport of photogenerated carrier electrons is still one of the main factors affecting the performance of photocatalytic hydrogen evolution. In this work, graphdiyne was prepared by ball milling method. The CoMo-MOF with polyhedral structure was introduced into graphdiyne to construct S-scheme heterojunction to promote the efficient transfer of photogenerated carriers and enhanced hydrogen evolution activity. Graphdiyne is a new carbon material with adjustable band gap, which is synthesized from the hybrid of sp and sp2, and has excellent electrical conductivity. CoMo-MOF is a polyhedral structure that can provide more active sites and promote photocatalytic hydrogen evolution. The weak point of poor conductivity in CoMo-MOF has been successfully improved by combining CoMo-MOF with graphdiyne, and the migration rate of photogenerated carriers has been accelerated. The hydrogen evolution property of graphdiyne/CoMo-MOF is 300 μmol, which is 19.61 times that of graphdiyne and 9.03 times that of CoMo-MOF. Therefore, the construction of S-scheme heterojunction provides a transport channel for electron transfer and improves the efficiency of photogenerated carrier separation. This work provides a new train of thought of design to introduce MOFs materials into carbon materials for photocatalytic hydrogen evolution.

Bio-efficacies of two different types of fungicides, Diniconazole and Paclobutrazol with their effects as plant g rowth regulators f or Kimchi Cab bage were e valuated o n February 4 to A pril 13, 2024 in Los Baños, Laguna, Philippines. The experiment was done during the off-season planting of Kimchi Cabbage in the country. Yield and other horticultural characteristics were observed for seven different groups: group 1, untreated control; group 2, recommended rate of granular fertilizer (RR-G); group 3, recommended rate of granular fertilizer plus recommended rate of Diniconazole; group 4, recommended r ate of D iniconazole (alone); g roup 5 , recommended rate o f Paclob utrazol (RR-PBZ), group 6, RR-G plus RR-PBZ; and group 7, RR-G plus ½ RR-PBZ. Results showed that combination of recommended rate of granular fertilizer plus the full recommendation of Paclobutrazol (group 6) resulted in a significantly higher yield of 64.9 tons/ha than other groups with yields ranging from 23.3 to 55.3 tons/ha. Such significantly higher yield in group 6 was also attributed to the number of leaves produced by plants at the time of harvest. Regarding effects of two chemical treatments, the combination of Diniconazole a nd P aclob utrazol a s recommended granular f ertilizers h elped in t he heading of K imchi Cabbage during hot conditions with an average temperature of 32-35°C from March to April at the heading stage plus a f actor of b eing planted a t a lowland area i n the country. T he a dvantage o f Paclobutrazol aside from yield is its availability in the country as compared to Diniconazole (Binnari).
