Determining the Optimum Night Length for Flower Development in a Modern Poinsettia Cultivar

The effect of night length (NL) on the flower development of poinsettia (Euphorbia pulcherrima Willd. ex Klotzsch) ‘Prestige Red’ was evaluated. Flower initiation occurred by subjecting plants to a 14-hour NL for 10 or 17 days, termed short-day (SD) treatments, and then transferring the plants to each of four NL treatments (11, 12, 13, or 14 hours) to observe the effects of NL on flower development. The plants grown continuously with the 14-h NL treatment were the control group. The timing of first color, visible bud, and anthesis were recorded during flower development, and bract and leaf data were collected at anthesis. Leaf number was unaffected by the SD or NL treatments, suggesting that flower initiation occurred during the 10-day SD treatment before the start of NL treatments; thus, the NL treatments only affected flower development. The timing of first color and visible bud were significantly delayed with the 10-day SD × 11-hour NL treatment relative to the 14-hour NL control; however, first color and visible bud were not delayed with the 17-day SD × 11-hour NL treatment. The 11-hour NL treatment resulted in fewer plants reaching anthesis, and these plants had fewer stem bracts and less bract color development compared with the 12-hour, 13-hour, and 14-hour NL treatments. Therefore, an 11-hour NL is suboptimal for flower development; nonetheless, significant development did occur. The 12-hour NL resulted in less color development than the 13-hour and 14-hour NL treatments in the lowest stem bract positions, but the plants had a commercially acceptable appearance. These results demonstrate that minimal differences in flower development occur with NL ≥12 hours, but that optimal development required NL ≥13 hours.

Bacteria as an Efficient Bacteriosystem for the Synthesis of Nanoparticles: A Bibliometric Analysis

The growth trend of publications in the field of nanoparticles biosynthesis by bacteria was analyzed using bibliometric techniques to the identification of the areas with significant development and the orientations that have guided the research on bacteria. This study extracted data from the Clarivate Analytics Web of Science (WoS) and Scopus between 2000 and 2020 to compare results. The number of articles published annually, participating countries, resource growth rate, most used keywords and research collaborations were obtained from bibliometric analysis. The results showed that nanoparticle documents in materials science, biochemistry, genetics and molecular biology have improved citation rates as the authors researched in multidisciplinary areas. Although these keywords have the most sites, they are not emerging keywords, and their most common use was in the years 2014–2018. The results showed the upward trend of articles published from 2000 to 2020, most of which were related to the last 10 years. The 5 countries that had the most articles published in this field were China, USA, India, Germany and Iran. The top sources that had the most published documents in this field had a similar scope to our research. The results of each section had a significant relationship with other sections of this study. VOS viewer program was used for quantitative analysis. It seems that bibliometric methods will complement meta-analysis and qualitative structured literature reviews as a method for reviewing and evaluating scientific literature. The advantage of the bibliographic analysis was the awareness of trends in a study area.

Mechanical and Corrosion Behavior of Friction Stir Welded AA 6063 Alloy

Friction stir welding (FSW) is considered to be the most significant development in solid state metal joining processes. This joining technique is energy efficient, environmentally friendly, and versatile. In particular, it can be used to join high-strength aerospace aluminum alloys and other metallic alloys that are hard to weld by conventional fusion welding. The project aims to join Aluminum 6063 alloy plates by FSW and emphasize the (1) mechanisms responsible for the formation of welds without any defects, microstructural refinement, and (2) effects of FSW parameters on resultant microstructure, mechanical, and corrosion properties.

Urgensi Pembentukan Undang-Undang Fintech Di Indonesia: Harapan Dan Realita Di Era Pandemic Covid-19

The growth of Fintech in Indonesia is very rapid, this condition is directly proportional to the legal problems that arise, the legal policy of regulation and protection of Fintech is still focused on the OJK, while the OJK still has many weaknesses in the implementation of supervision and protection of fintech activities, especially in the era of the covid pandemic. -19. The purpose of this study, first, by outlining the legal regulations issued by Bank Indonesia and the Financial Services Authority regarding fintech in Indonesia by looking at the legal weaknesses so that it is important to establish the Fintech Law. second, the urgency of the establishment of a fintech law on fintech consumer protection in Indonesia. Meanwhile, the importance of this research is that it will explain the development of the fintech industry in Indonesia, especially during the Pandemic, where the fintech industry experienced significant development so that this is an idea to provide a clear legal framework for the fintech industry. The research method used is normative juridical using library data and observations of fintech developments through library studies. Research findings show that so far fintech in Indonesia has used regulations contained in the POJK and PBI as the basis for implementing fintech, although it is felt that the regulations issued by POJK and PBI have not been able to provide maximum legal protection for the implementation of the fintech industry. so it is necessary to establish a law in order to provide legal protection for the development of the fintech industry now and in the future.

Global Value Chain: Islamic Economics and Finance Position

The growing number of Muslim populations promotes significant development on Islamic economic and finance activities called halal industry. While the halal industry is experiencing positive growth in the last four years, the Global Value Chain (GVC) – the chain of system that drives international trades and global economic activities – remains stagnant. The present study aims to explain the position of the Islamic economics and finance in the GVC. This study employs a qualitative-descriptive method with systematic literature review approach. By collecting secondary data using strict-processing stages and content analysis techniques, the author manages to meet the study’s purpose. The findings suggest that the Islamic economics and finance have opportunities to boost countries' participation in the GVC activities by harmonizing halal standardization, enhancing financial infrastructures, and providing various financial products. This study contributes to generate government policies and enterprises' decisions in developing the Islamic economics and finance within the GVC framework. It further provides initial insights and potential topics for future studies.

Phytochemical Profile and Anticancer Potential of Endophytic Microorganisms from Liverwort Species, Marchantia polymorpha L.

Liverwort endophytes could be a source of new biologically active substances, especially when these spore-forming plants are known to produce compounds that are not found in other living organisms. Despite the significant development of plant endophytes research, there are only a few studies describing liverwort endophytic microorganisms and their metabolites. In the presented study, the analysis of the volatile compounds obtained from thallose liverwort species, Marchantia polymorpha L., and its endophytes was carried out. For this purpose, non-polar extracts of plant material and symbiotic microorganisms were obtained. The extracts were analyzed using gas chromatography coupled to mass spectrometry. Compounds with the structure of diketopiperazine in the endophyte extract were identified. Liverwort volatile extract was a rich source of cuparane-, chamigrane-, acorane-, and thujopsane-type sesquiterpenoids. The cytotoxicity of ethyl acetate extracts from endophytic microorganisms was evaluated on a panel of cancer (FaDu, HeLa, and SCC-25) cell lines and normal (VERO), and revealed significant anticancer potential towards hypopharyngeal squamous cell carcinoma and cervical adenocarcinoma.

Self-healing mortar using different types, content, and concentrations of bacteria to repair cracks.

The creation of cracks, which are the most common cause of structural failure, has a significant impact on the structure's strength and durability. As a result, effective repair and maintenance are vital and unavoidable for treating any of these issues. Self-healing mortar holds promising benefits for reducing the cost of repair as cracks are autonomously repaired without any human intervention. This study investigated the effect of bacteria type, bacteria content, bacteria concentration, and nutrient type on the properties of the self-healing mortar. Three types of bacteria, Bacillus sphaericus, Bacillus Megaterium, and Bacillus subtilis encapsulated in calcium alginate beads, were introduced into the mortar. Two concentrations of bacteria, 2× 108 and 2× 109 Colony Forming Units per milliliter, and different percentages of bacteria of cement weight were selected for the study. In addition, calcium lactate and calcium acetate were used at 0.5% of cement weight as nutrition for bacteria. Tests were performed for compressive strength, bending strength, SEM, EDX, and TGA/DTG. The results show a significant development in the mechanical behaviour of mortar, especially with Bacillus Megaterium using a 2.5% bacterial proportion with a concentration 2× 109 CFU/ml. This can be related to the filling of voids and cracks in microbial mortar by calcite, which was confirmed by SEM and EDX.

A New Genetic Insight for Orphan Renal Disorder, Fabry: A Review

Fabry is the rare X-linked genetic disorder caused due to mutation in Alpha –Galactosidase encoding GLA gene mutation in chromosome number 22. It has wide diversification in prevalence due to clinical heterozygosity. There are some potential biomarkers for the evaluation of normal or altered genes responsible for Fabry. Advances in the research of biomarkers over the years have made significant development for several clinical indicators, viz. urine-derived cells, oxidative stress, DNA methylation, etc. At present days the recommended therapies for the disease are Enzyme Replacement Therapy (ERT), Chaperone therapy (CT), and mRNA-based therapy, besides, some second-generation therapies which are still under clinical trials.

Representing a Relationship: The use of metadata to represent the relationship between physical objects and their digital surrogates

<p>Digital collections are increasingly prominent in museums as born-digital material is acquired by institutions, and digital surrogates of physical items are created through digital imaging, digitisation, and reformatting projects. These digital collections are a significant development in museums and a useful tool, particularly for access. When a digital surrogate is created of a physical object, they have an inherent connection to one another. Representing this relationship is important for museums in order to provide context for their collection items. These types of relationships also occur across physical formats, and the consequence of a breakdown in this relationship has been shown in the literature to lead to a loss of context. However, it is unclear how the relationship a physical object has with its digital surrogate is represented in the metadata. Current literature on digital collections only briefly explores existing relationships between digital and physical collections and provides no framework for best practice in a museum context. This thesis examines how metadata is used to represent the relationship between a physical object and its digital surrogate at the Museum of New Zealand Te Papa Tongarewa. The research involved a single-site case study, with interviews and documentary research which were thematically analysed. This thesis shows how the relationship between physical and digital objects are primarily represented at Te Papa through the collection management system’s structure, with some metadata elements representing the relationship incidentally. It also shows that there are differing worldviews and perspectives across the GLAM domains in the language and the drivers of digitisation. This research serves as a snapshot of current practice at one institution and encourages further research to better understand the long-term implications of this and other approaches. For museums, understanding how the relationship between physical objects and digital surrogates is currently being represented through metadata could help support professional practice for both types of collections, ensure the relationship is maintained, and help support existing and future digital interventions in museums.</p>
