Phytochemistry and pharmacological studies on Solanum torvum Swartz
No full textThe botany, traditional medicinal uses, phytochemistry, and pharmacology of S. torvum Sw. belonging to family Solanaceae have been reviewed by evaluating information on the Internet (using Google Scholar, CABAbstracts, Blackwell synergy, Elsevier, Cambridge University Press, JSTOR, Nature Publishing and Science online) and in libraries. Traditional medicinal uses of S. torvum were recorded in the Ayurveda and Chinese pharmacopeia. The present review study covered chemical constituents and pharmacological properties of S. torvum as well as its morphology. This has included therapeutic effects of the whole plant and its extracts, fractions and isolated compounds. Antimicrobial, anti-ulcerogenic, antiviral, anti-platelet aggregation, antioxidant, analgesic, anti-inflammatory, systolic blood-pressure modification, and cytotoxic activities have all been described. Previous research studies carried out using different in-vitro and in-vivo bioassay techniques supported the claims of the therapeutic utility of the species. © 2013 Zubaida Yousaf et al
AI-Generated Test Scripts for Web E2E Testing with ChatGPT and Copilot: A Preliminary Study
No full textAutomated testing is vital for ensuring the reliability of web applications. This paper presents a preliminary study on leveraging artificial intelligence (AI) models, specifically ChatGPT and Github Copilot, to generate test scripts for web end-to-end testing. Through experimentation, we evaluated the feasibility and effectiveness of AI language models in generating test scripts based on natural language descriptions of user interactions with web applications. Our preliminary results show that AI-based generation generally provides an advantage over fully manual test scripts development. Starting from test cases clearly defined in Gherkin, a reduction in development time is always observable. In some cases, this reduction is statistically significant (e.g., Manual vs. a particular use of ChatGPT). These results are valid provided that the tester has some skills in manual test script development and is therefore able to modify the code produced by the AI-generation tools. This study contributes to the exploration of AI-driven solutions in web test scripts generation and lays the foundation for future research in this domain
Brand Associations in the Digital Age: How Perceived Authenticity, Trendiness, and Trust worthinesson Social Media Influence Brand Relevance and Engagement Among Generation Z
No full textABSTRACT Date: 2025-05-16 Level: Master thesis in Business Administration, 15 cr Institution: School of Business, Society and Engineering, Mälardalen University Authors: Ali Yousaf Noura Almenayes (2000/04/08) (1996/05/22) Title: Brand Associations in the Digital Age: How Perceived Authenticity, Trendiness, and Trustworthiness on Social Media Influence Brand Relevance and Engagement Among Generation Z Supervisor: Olivia Kang Keywords: Brand Associations, Generation Z, Authenticity, Trendiness, Trustworthiness, Social Media Marketing Research questions: “To what extent do Gen Z consumers’ perceptions of authenticity, trendiness, and trustworthiness, formed through exposure to Instagram and TikTok advertising, influence brand relevance and consumer engagement?” Purpose: To examine how social media advertising on Instagram and TikTok shapes Generation Z’s perceptions of authenticity, trendiness, and trustworthiness, and how these perceptions influence brand relevance and engagement. Method: A quantitative, cross-sectional survey was conducted with 101 Gen Z participants. Data were analyzed using descriptive statistics, reliability testing, and multiple regression analysis in SPSS. Conclusion: Trendiness and trustworthiness were found to significantly influence both brand relevance and engagement, while authenticity only predicted brand relevance. These findings highlight that Gen Z favors trendy and trustworthy content for interaction but reserves authenticity as a filter for value alignment. Marketers are advised to integrate trend-driven strategies while maintaining transparency and credibility to nurture brand relationships

Structural, elastic, electronic, bonding, and optical properties of BeAZ(2) (A = Si, Ge, Sn; Z = P, As) chalcopyrites
No full textA first principles density functional theory (DFT) technique is used to study the structural, chemical bonding, electronic and optical properties of BeAZ(2) (A = Si, Ge, Sn; Z = P, As) chalcopyrite materials. The calculated parameters are in good agreement with the available experimental results. The lattice constants and the equilibrium volume increased as we moved from Si to Ge to Sn, whereas the c/a and internal parameters u decreased by shifting the cation from P to As. These compounds are elastically stable. An investigation of the band gap using the WC-GGA, EV-GGA, PBE-GGA and mBJ-metaGGA potentials suggested that BeSiP2 and BeSiAs2 are direct band gap compounds, whereas BeGeP2, BeGeAs2, BeSnP2, BeSnAs2 are indirect band gap compounds. The energy band gaps decreased by changing B from Si to Sn and increased by changing the anion C from P to As. The bonding among the cations and anions is primarily ionic. In the optical properties, the real and imaginary parts of the dielectric functions, reflectivity and optical conductivity have been studied over a wide energy range
The Benefits of Being Economics Professor A (and not Z)
No full textAlphabetic name ordering on multi-authored academic papers, which is the convention in the economics discipline and various other disciplines, is to the advantage of people whose last name initials are placed early in the alphabet. As it turns out, Professor A, who has been a first author more often than Professor Z, will have published more articles and experienced afaster growth rate over the course of her career as a result of reputation and visibility. Moreover, authors know that name ordering matters and indeed take ordering seriously: Several characteristics of an author group composition determine the decision to deviate from the default alphabetic name order to a significant extent.performance measurement, incentives, economists, name ordering
Final word on Jersey Dutch
No full textIn this article, William Z. Shetter compares and contrasts the dialects that developed between different Dutch colonies in the New World. He explores in-depth the nuances of Jersey Dutch, and provides theories to explain how Dutch and colonial languages blended.

Plants of the genus Allium as antibacterial agents: From tradition to pharmacy
No full textPlants belonging to the genus Allium are widely cultivated and used all over the world as food and medicinal plants. Since ancient times, these plants, particularly garlic (Allium sativum L.) and onion (Allium cepa L.), have represented important components of typical recipes and traditional healing systems. Not the least of which, their use as food biopreservatives is well documented, due to the relevant antibacterial activity of their extracts and essential oils. In addition to garlic and onion, this review article deals with the main members of the genus Allium, including A. ampeloprasum (Leek), A. schoenoprasum (Chive) and A. ascalonicum (Shallot), focusing both on their ethnonutritional uses and potential as promising food biopreservative agents. Noteworthy, recent research has demonstrated Allium derivatives to be novel components in active edible coatings as well as nanoformulates

Logarithmic variance profiles and the corresponding f-1 spectra of temperature fluctuations in turbulent Rayleigh-Bénard convection
No full textWe report experimental results for the temperature variance 2(z) and the corresponding frequency spectra P(f) in turbulent Rayleigh-Bénard convection (RBC) in a cylindrical sample of aspect ratioT= D/L = 1:00 (D = 1:12 m is the diameter and L = 1:12 m the height). The measurements were conducted in the Rayleigh-number range 1011 < Ra < 1:35 1014 and Pr ' 0:8. For Ra = 1:35x1014, 2(z) could be described well by a logarithmic dependence on the vertical position z in a range of z 1 < z < z 2 with z 1 ' 70 and z 2 = 0:1L. Here L=(2Nu) is the thickness of a thin thermal sublayer adjacent to the horizontal plate where the heat flux (denoted by the Nusselt number Nu) is carried mostly by thermal diffusion. In the log layer, we found that the temperature spectra had a significant frequency range over which P(f) f with close to 1. As Ra decreased, increased so that the log layer became thinner. At Ra = 2:05 1011, z 2 < z 1 and therefore there was no range for a log layer. Correspondingly, the temperature spectrum near the horizontal plate did not have the f1 scaling form either
