Karyotype analysis of three species of Allium (Amaryllidaceae) from Thailand

Saensouk S, Saensouk P. 2021. Karyotype analysis of three species of Allium (Amaryllidaceae) from Thailand. Biodiversitas 22: 3458-3466. Comprehensive karyotype analysis of three species of Allium from Thailand has not been reported. This work aims to study karyotype analysis of three species of Allium from Thailand. It is confusing due to the use of the common name or local name or local Thai name and morphologies. The karyotype analysis of three species with two variations in the genus Allium from Thailand were studied from root tips and observed under a microscope then karyotype was obtained from 10 metaphase plates. The chromosome numbers of them were found 2n = 16. The karyotype formulas of them were constructed as 14m + 2st (Allium ascalonicum L. or shallot), 12m + 2sm + 2st (A. cepa L. or onion), 10m + 6sm (1 sat) (A. cepa L. or red onion), 10m + 4sm + 2st (A. sativum L. or big garlic or Chinese garlic) and 8m + 6sm + 2st (A. sativum L. or small garlic or Thai garlic). Chromosome structure differences among the three species appeared in the number of m, sm and st chromosomes and the satellites at the end of the short arm of A. cepa L. (red onion). This is new data on chromosome structure of the genus Allium. Moreover, the karyotype formulas, chromosome structures and satellites of this study should be used for classification of Allium from Thailand.
Vitamin C supplementation in aquaculture activities

This study investigated the effects of different levels of vitamin C in diet of fish with oxidative stress biomarkers and hematological parameters of silver catfish. Juvenile fish were divided into three groups, and fed with different amounts of vitamin C: 1) 0, 2) 500, and 3) 1,000 mg kg-1. Ten fish per group were collected at 0, 14, and 28 days after the beginning of the experiment. Liver catalase activity increased in group 1 after 28 days. The GPx activity in gills decreased in all groups, and the hepatic GPx activity increased in groups fed with vitamin C. SOD hepatic activity and NPSH levels in gills and liver were not affected. In all groups, the GST activity in gills decreased, and the GST activity in liver increased. The levels of lipid peroxidation decreased in liver and gills for groups 2 and 3. This study’s results indicate that both diets with 500 or 1,000 mg/kg of vitamin C contributed to the decrease in the oxidative damage of Rhamdia quelen, suggesting that vitamin C supplementation in the present experimental model could be useful in aquaculture to overcome possible oxidative changes induced by adverse environmental conditions.
User experience assessment of a COVID-19 tracking mobile application (AMAN) in Jordan

This study assesses the user experience of a COVID-19 tracking application, as employed as a case study of AMAN mobile application based on user experience. This paper proposed an assessment of user experience (UX) for AMAN application (COVID-19 tracking mobile application in Jordan) by implementing a user experience questionnaire tool. The study aims to get feedback and identify UX based on user interaction and usage with the tracking application. The data are taken from 1208 participants who have experience using the application; an online questionnaire was implemented and distributed through social media groups. The research method that was adopted used the instrument from user experience questionnaire (UEQ) of Arabic and English versions. The results from the UX assessment using UEQ showed that there are four scales which are categorized as excellent; they are Attractiveness (Mean=1.9), Efficiency (Mean=2.4), Dependability (Mean=2.1), Stimulation (Mean=1.8), while the two scales on the benchmark of good are Perspicuity (Mean=2.0) and Novelty (Mean=1.6). From the scores, above < 0.8 show a positive evaluation. All scores are above >0,08 indicating that the evaluation of UX has a positive impression. It can be concluded that the AMAN application is very good–satisfying users to track infected cases of COVID 19.
Fiscal Decentralization and Gender Parity in Developing Asia

Sidra Naeem1 Mahnaz Muhammad Ali2 Abstract The traditional fiscal decentralization theorem claims that decentralized government can provide the goods and services at local level more efficiently. However, empirically it is still to explore that how fiscal decentralization affects gender parity. This study empirically investigates the impact of fiscal decentralization on gender parity in developing economies of Asia, Armenia, Azerbaijan, Indonesia, Iran, Kazakhstan, Kyrgyz, Mongolia, Myanmar, Thailand and Turkey. The study used dynamic penal da ta technique namely system GMM over the period of 2006-2020. The multidimensionality of fiscal decentralization is captured through three measures of fiscal decentralization i.e. expenditure decentralization, revenue decentralization and composite decentralization. Further, it also examines the complementarity between fiscal decentralization and control of corruption to increase the gender parity. The results of the analysis show that expenditure decentralization is increasing the gender parity in developing economies of Asia. Additionally, control of corruption is a necessary reform to get the desired fruits of fiscal decentralization. Countries must focus on corruption aspect of local governments in implementing the expenditure, revenue and composite decentralization.
Colloidal Nanocomposite of TiN and N-Doped Few-Layer Graphene for Plasmonics and Electrocatalysis

A combination of high carrier density, high surface area, solution processibility, and low-cost are desired in a material for electrocatalytic applications including H2 evolution and counter electrode of a solar cell. Also, plasmonic based applications in biological systems can be derived from such material. In this regard, colloidal nanocomposite of TiN and N-doped few-layer graphene (TiN-NFG) is synthesized from molecular precursors. TiN nanocrystals (NCs) provide free electrons for electrical conductivity and plasmonics, whereas NFG is responsible for charge transport, high surface area and colloidal stability. Colloidal TiN-NFG nanocomposites exhibit localized surface plasmon resonance band around 700 nm. Coatings of the nanocomposite forms counter electrode for efficient (8.9 %) dye sensitized solar cells. Furthermore, the nanocomposite acts as an efficient electrocatalyst for hydrogen evolution reaction exhibiting overpotential ~ 161 mV at a current density of 10 mA/cm2
A novel technique for nipple reduction surgery: the tripod wedge resection method

Breasts are important for women in terms of both functional and aesthetic aspects, the latter of which can also have psychological implications. The nipple is one of the most important factors affecting the function and shape of the breast. Some women experience emotional distress associated with their nipple size or shape, especially if it is large or ptotic. The epidemiology of nipple deformity is unknown, but it seems to be common in Asian populations [1]. In women who experience psychological stress due to the shape of their nipples, nipple reduction surgery could be very helpful. There are four major surgical techniques for nipple reduction: circumcision, amputation, wedge resection, and flaps [2]. These four techniques are illustrated in Fig. 1. Each technique has advantages and disadvantages, which are mainly associated with the aesthetic outcome, preservation of lactiferous ducts, and complexity of the surgical technique. Although aesthetically unsatisfactory results and scarring/contracture have not been described for any surgical techniques, it is reasonable to presume that wedge resection and flap techniques may result in postoperative surgical scars due to their asymmetric design [3-5]. Regarding the patency of lactiferous ducts, which is especially important in breastfeeding women, circumcision, amputation, and wedge resection may impair the ability to lactate. Although the flap and wedge resection techniques involve complicated surgical techniques, we regard this aspect as a relatively unimportant issue when considering their more satisfactory outcomes. From the perspective of these considerations, we present a novel technique that has benefits in terms of its symmetric design, resulting in good aesthetic outcomes, and preservation of the lactiferous ducts, enabling breastfeeding.

Outdoor SLAM Using Monocular Vision-Based Localization with LIDAR-Aided Mapping for service robot in Highway

This paper designed an intelligent service robot system in highway based on multi-sensor fusion. The mobile robot attempts to fuse the lidar information and monocular vision information to estimate the pose of itself and obtain an environmental map. It adapts a new SLAM method which combines lidar and vision information. Lidar is used to obtain the 2D occupancy grid map and the monocular vision SLAM algorithm uses the Extended Kalman Filter (EKF) to magnify the pose estimation. The 3-DOF pose provided by lidar is obtained through Cartographer algorithm and the monocular vision SLAM who offers the 6-DOF pose is realized with ORB-SLAM. The experimental results show that the system is effective in application as an intelligent service robot of highway.
Designs of Frequency Reconfigurable Planar Bow-tie Antenna Integrated with PIN, varactor diodes and Parasitic Elements

A R T I C L E I N F O A B S T R A C T Article history: Received: 11 February, 2021 Accepted: 11 July, 2021 Online: 16 August, 2021 This paper presents the designs and the simulations of proposed structures of electronically frequency reconfigurable planar bow-tie antenna. In the first part, a modified wide band self-complementary bow-tie antenna is designed and implemented. In the second part, varactor and PIN diodes are integrated in top side to adjust electronically the modified structure of bow-tie antenna over multi-band frequency. By adjusting PIN diode between the two states and by tuning the varactor diode inside these two states; the proposed antenna demonstrates two different operational frequencies. In ON state, the antenna covers a narrow frequency bands and in OFF state the antenna demonstrates a wide-band operational frequency. Furthermore, a new structure of reconfigurable antenna implemented with PIN diode and two hexagonal parasitic elements is developed to realize a multi-band operational frequency band and to cover GPS and GMS bands. Simulated results show a return loss less than -10dB with a gain varied between 0.5 and 3.5dB.
Corporate Governance, Financial Leverage, and Performance of Sharia Manufacturing Companies on the Indonesia Stock Exchange

This paper discusses the impact of corporate governance on the leverage effect and the leverage effect on corporate performance. The study was conducted on Islamic manufacturing companies on the Indonesia Stock Exchange during the period 2012 to 2018. The data analytics method used Partial Least Square (PLS) which was handled with the WarpPLS application. The results show that almost all proxies of the corporate governance variable negatively affect financial leverage variable, except for the Independent Board of Commissioners (ICB) which has a positive effect on book leverage (BLEV). Furthermore, financial leverage as proxy by book leverage (BLEV) shows a positive effect on market performance (TBQ) and negative effect on book performance (ROA). The financial leverage effect by market leverage variable (VEML) has a negative effect on market performance (TBQ) as well as on accounting performance (ROA). An important implication of this study is that in general, Shariah manufacturing companies that are more profitable tend to reduce their financial leverage, and investors can better recognize the relationship between financial leverage decisions and firm performance.
The economic costs of biological invasions in Africa: a growing but neglected threat?

Biological invasions can dramatically impact natural ecosystems and human societies. However, although knowledge of the economic impacts of biological invasions provides crucial insights for efficient management and policy, reliable syntheses are still lacking. This is particularly true for low income countries where economic resources are insufficient to control the effects of invasions. In this study, we relied on the recently developed "InvaCost" database – the most comprehensive repository on the monetised impacts of invasive alien species worldwide – to produce the first synthesis of economic costs of biological invasions on the African continent. We found that the reported costs of invasions ranged between US$ 18.2 billion and US$ 78.9 billion between 1970 and 2020. This represents a massive, yet highly underestimated economic burden for African countries. More alarmingly, these costs are exponentially increasing over time, without any signs of abatement in the near future. The reported costs were mostly driven by damage caused by invaders rather than expenses incurred for management. This trend was highly skewed towards a few regions (i.e. Southern and Eastern Africa) and activity sectors (i.e. agriculture) and incurred by a small number of invasive taxa (i.e. mainly three insect pests: Chilo partellus, Tuta absoluta, Spodoptera frugiperda). We also highlight crucial, large gaps in current knowledge on the economic costs of invasions that still need to be bridged with more widespread research effort and management actions across the continent. Finally, our study provides support for developing and implementing preventive measures as well as integrated post-invasion management actions at both national and regional levels. Considering the complex societal and economic realities in African countries, the currently neglected problem of biological invasions should become a priority for sustainable development.
INVESTIGATION OF AROMATICITY OF TRI AND TETRAAZANAPHTHALENE DERIVATIVES

Aromaticity of a compound gives important information about the possible reactions and other propeties of a molecule. In that point of view measurement of aromaticity is very important. Although there are a few applications for the determination of aromaticity, Nucleus Independent Chemical Shift calculations provide the easiest computation and best approach to the result. Naphthalene is an aromatic molecule with two fused benzene rings. It is clear that centric replacement of carbons with heteroatoms will affect the aromaticity of naphthalene. Substitution of parent carbon atoms of the ring with electronegative nitrogen atoms will decrease the aromaticity of the system. The positions of the nitrogens should also effect the aromaticity of the total system. Therefore, this work was formed by taking all the derivatives of tri and tetraazanaphthalene derivatives into consideration. In order to gain the lost aromaticity due to nitrogen substitution, ring hydrogens were substituted with electron withdrawing nitro groups.

Chirality inversion, supramolecular hydrogelation and lectin binding of two thiolactose amphiphiles constructed on a di-lauroyl-L-tartaric acid scaffold

Herein we report the synthesis, characterization and self-assembly properties of two new thiolactose based amphiphiles constructed on a di-lauroyl-L-tartaric acid scaffold that only differ in the length of the spacer by an ethylene glycol unit. Upon dissolution in hot water the amphiphiles give rise to different colloidal systems at 25 °C: the one with the shorter linker forms a supramolecular thermoreversible hydrogel at a concentration of 0.1 w/v% while the other renders a colloidal system at high dilution (0.005 w/v%). Dynamic Light Scattering, Electron Microscopy (TEM, SEM and E-SEM), fluorescence CMC determination, SAXS and Circular Dichroism experiments were used to characterize both systems. The experiments indicate that only the amphiphile carrying the shorter linker is able to form a crossed-linked network of micellar fibers and thus, a stable hydrogel is observed. The difference of an ethylene glycol unit in the spacer also causes the adoption of a different molecular assembly evidenced by the inversion of the self-assembled chiral arrangement. In addition, the amphiphiles were evaluated for their ability to bind to the PNA lectin using a turbidimetric method. Agglutination was observed in both cases, a process that was disrupted upon the addition of an excess of the disaccharide lactose.
Detektoren mit effizienter und schneller Phononensammlung für das CRESST-Experiment

In der CRESST-Kollaboration werden Tieftemperaturdetektoren eingesetzt um nach schwach wechselwirkenden, massiven Teilchen zu suchen, die favorisierte Kandidaten fur die "Dunkle Materie" im Universum sind. Die gleichzeitige Messung von angeregten Phononen und Szintillationslicht in CaWO4-Kristallen erlaubt eine sehr effiziente Identifizierung von durch ionisierende Strahlung erzeugten Untergrundsignalen. In vorliegender Arbeit wurde ein Detektormodul, bestehend aus Phonon- und Lichtdetektor, entwickelt welches mit seiner Schnelligkeit und Stabilitat den Anforderungen einer Eichung mit einer hohen Zahlrate genugt. Hierfur wurde fur beide Detektoren das Konzept des QET (Quasiparticle-trap-assisted Electrothermal-feed-back Transition-edge-sensor) angewendet. Fur die Lichtdetektoren wurde erstmals erfolgreich der Neganov-Luke-Effekt getestet.
The Unconventional Cytoplasmic Sensing Mechanism for Ethanol Chemotaxis in <named-content content-type='genus-species'>Bacillus subtilis</named-content>

Motile bacteria sense chemical gradients using chemoreceptors, which consist of distinct sensing and signaling domains. The general model is that the sensing domain binds the chemical and the signaling domain induces the tactic response. Here, we investigated the unconventional sensing mechanism for ethanol taxis in Bacillus subtilis. Ethanol and other short-chain alcohols are attractants for B. subtilis. Two chemoreceptors, McpB and HemAT, sense these alcohols. In the case of McpB, the signaling domain directly binds ethanol. We were further able to identify a single amino acid residue, Ala431, on the cytoplasmic signaling domain of McpB that, when mutated to serine, reduces taxis to alcohols. Molecular dynamics simulations suggest that the conversion of Ala431 to serine increases coiled-coil packing within the signaling domain, thereby reducing the ability of ethanol to bind between the helices of the signaling domain. In the case of HemAT, the myoglobin-like sensing domain binds ethanol, likely between the helices encapsulating the heme group. Aside from being sensed by an unconventional mechanism, ethanol also differs from many other chemoattractants because it is not metabolized by B. subtilis and is toxic. We propose that B. subtilis uses ethanol and other short-chain alcohols to locate prey, namely, alcohol-producing microorganisms. IMPORTANCE Ethanol is a chemoattractant for Bacillus subtilis even though it is not metabolized and inhibits growth. B. subtilis likely uses ethanol to find ethanol-fermenting microorganisms to utilize as prey. Two chemoreceptors sense ethanol: HemAT and McpB. HemAT’s myoglobin-like sensing domain directly binds ethanol, but the heme group is not involved. McpB is a transmembrane receptor consisting of an extracellular sensing domain and a cytoplasmic signaling domain. While most attractants bind the extracellular sensing domain, we found that ethanol directly binds between intermonomer helices of the cytoplasmic signaling domain of McpB, using a mechanism akin to those identified in many mammalian ethanol-binding proteins. Our results indicate that the sensory repertoire of chemoreceptors extends beyond the sensing domain and can directly involve the signaling domain.
Driving Engagement on Instagram: A Comparative Analysis of Amazon Prime and Disney+

ARTICLE INFO PurposeThis paper dives into the engagement patterns exhibited on Instagram by two streaming heavyweights; Amazon Prime and Disney+. With ever-growing popularity among the younger generation, Instagram is vital for driving engagement in the social media ecosystem. Hence, it is crucial to understand what content posted by streaming services fosters engagement on this platform. Design/MethodologyA combined total of 230 Instagram posts appearing between January 14 and February 28, 2021, were extensively analyzed. The goal was to examine the post objectives, features, and emotional elements accompanying said posts that Amazon Prime and Disney+ uploaded. Special attention was paid to the number of likes on posts since it is a key metric in measuring engagement. FindingsResults indicate that, despite having fewer posts per day, Disney+ drove much more engagement in post likes and comments. The platform made extensive use of hashtags and entertaining content to engage audiences. However, Amazon Prime had a big absence of useful features like hashtags. It also relied heavily on third-party content, unlike Disney+, whose content primarily consists of original programming. Practical ImplicationsThe novel findings have important implications for streaming services, social media practitioners, and researchers.
