Alkaline rocks and their economic and geodynamic significance through geological time
No full textAlkaline igneous rocks have a relative excess of alkalis over silica. Most are silica undersaturated and contain normative nepheline and real feldspathoids (nepheline, leucite). Although alkaline rocks make up only about 1% of total igneous rocks by volume, their diverse mineralogy accounts for 90% of all igneous rock names proposed by the IUGS. They occur in all tectonic settings; in the ocean basins and on the continents, along mid-ocean ridges (rare), on oceanic islands, in subduction zones in the oceans and along continental margins, as well as along rift zones. Alkaline rocks commonly include alkali basalts and foidites, tephrites, phonolites, trachytes and their intrusive equivalents, including lamprophyres and carbonatites. In the literature, a plethora of local names for alkaline rocks from different localities have been created and many geoscientists still consider them as petrological curiosities. However, their study can significantly aid the interpretation of mantle evolution, ancient terranes and their geodynamic settings. Additionally, alkaline rocks may host world-class precious- and rare-metal mineralization. During recent years, the exploration interest in critical and rare metal deposits (Nb, rare earth elements (REEs) and Th) has increased dramatically as they represent vital resources for the so-called ‘green energy transition’. This Special Publication presents new comprehensive data, results and findings on alkaline rocks from different terranes worldwide and uses their mineralogy and geochemical fingerprints in order to elucidate their petrogenesis, tectonic settings and mineralization potential. This volume is not only of interest for igneous petrologists, but also for exploration geologists prospecting for precious- and rare-metal mineralization worldwide
Global work arrangements and outsourcing in the age of AI
No full textThe rise of AI has reshaped outsourcing and work arrangements in global businesses, transforming how businesses operate and allocate tasks across borders. The use of AI in automation and intelligent workflow management, which enables companies to streamline operations, reduces costs and enhances productivity. While outsourcing has long been a strategy for optimizing labor costs and accessing specialized talent, AI further revolutionizes this landscape by automating routine tasks and augmenting human capabilities. Further exploration may reveal new applications of intelligent technology in the global workforce.

Alkali-free bioactive glass composition, U.S. Patent 9,238,044
No full textThe present invention relates to development of bioactive glass/glass-ceramic composition that are able to promote a fast deposition layer of carbonated hydroxyapatite upon immersion in simulated body fluid (SBF) for time periods as short as one hour. Such composition might include fluorides, and a variety of oxides (or their precursor compounds), such as Na2O—Ag2O—SrO—CaO—MgO—ZnO—P2O5—SiO2—Bi2O3—B2O3—CaF2, be prepared by the melt route or by the sol-gel process, with the specific composition and the preparation route selected according to the intended functionalities, which can present controlled biodegradation rate and bactericidal activity. The powders derived from glass melts purred in cold water (frits) may completely densify by sintering at temperatures up to 800° C. without devitrification, resulting in bioglass compacts with high flexural strength (˜85 MPa). The bioactive glass powders prepared by sol-gel densify at lower temperatures due to their higher specific surface area and reactivity
Transformational HR for Generation Z : gig economy efficiency and adaptability
No full textThe contemporary workforce is being radically transformed by the emergence of Generation Z and the explosive growth of the gig economy. Gen Z differs from other generations in valuing flexibility, autonomy, and purposeful work more than the long term employment model. Their technological literacy has redefined work standards, with freelancing, temporary contracts, and remote work becoming the new norm. While this trend is beneficial in the sense that it provides work-life balance and diversified sources of income, it has challenges in employment security, mental well-being, and career advancement. HR practitioners need to shift by embracing innovation, technology, and flexibility. The old model of employment does not suit Gen Z's needs anymore, calling for dynamic practices such as on-demand learning, customized benefits, and AI-enabled talent management. Yet, aligning digital evolution with a people-centric strategy continues to be the key
Role of Artificial Intelligence in Enhancing Employee Well-Being at the Workplace
No full textThe whole world is rushing towards Artificial Intelligence; it has revamped every dimension of our lives. Now, various companies are utilizing AI to improve employee well-being. This chapter is an attempt to understand the role of AI in enhancing employee well-being at the workplace. It examines AI-driven solutions for monitoring employee engagement, stress levels, and overall job satisfaction. AI-powered tools, such as mental health chatbots, predictive burnout models, and personalized wellness programs, contribute significantly to workplace efficiency and employee retention. However, the integration of AI into well-being initiatives also raises ethical concerns regarding data privacy, algorithmic bias, and employee trust. This study emphasizes the need for a human-centered approach that balances AI automation with personal interaction. By ensuring transparency, regulatory compliance, and ethical implementation, organizations can successfully leverage AI to foster a healthier, more engaged, and productive workforce

Multilevel Nanophotonic Resistive Switching in Ag-ITO-SiO2 on Silicon with Enhanced Optical Storage Density
No full textMultilevel resistive devices have gained a lot of research attention in the past decade due to their attractive potential applications in high-density non-volatile memory, and unconventional computing. We propose an engineered multilevel nanophotonic resistive switching device with CMOS compatible Ag-ITO-SiO 2 structure on silicon for enhanced storage density and in-memory computing with optical readout functionality. The four-layered structure includes a SiO2/ITO region strategically positioned between an efficient Ag (top) electrode and an underlying p-Si bottom electrode. The engineered nanophotonic device confined hybrid plasmonic mode, mainly in the SiO2 region and with an applied voltage conductive filaments form/deform along ITO and SiO2 layers influencing optical absorption detectable through interaction between the guided hybrid plasmonic mode and conductive filaments. The proposed device achieves stable multiple optical states by controlling compliance current, storing two bits without compromising accuracy to enable parallel computing, and efficient area savings with enhanced storing density for in-memory computing applications on a photonic platform. Additionally, the experimental results demonstrate a significant extinction ratio of 32 dB for the 10 μm × 500 nm device with a low voltage operation. The engineered nanophotonic structure exhibits high retention, high endurance, low operating power, and high speed, making it suitable for various applications, including optical modulation, neuromorphic computation, biochemical sensing, photogating and high-density advanced memory devices
