    Inkjet printing of functional frequency selective surfaces (FSS) and radio frequency identification (RFID) tags on commercial paper substrates using silver nanoparticle inks sintered using low temperature thermal, plasma and photonic techniques is reported. Printed and sintered FSS devices demonstrate performances which achieve wireless communication requirements having a forward transmission scattering parameter, S21, depth greater than ?20 dB at 13 GHz. Printed and plasma sintered RFID tags on transfer paper, which are capable of being mounted on skin, improved read distances compared to previously reported single layer transfer RFID tags fabricated by conventional thermal sintering

    Modeling of primary dendrite arm spacing variations in thin-slab casting of low carbon and low alloy steels

    Solidification structure of a High Strength Low Alloy (HSLA) steel, in terms of dendrite arm spacing distribution across the shell thickness, is studied in a breakout shell from a thin-slab caster at Tata Steel in IJmuiden. Columnar dendrites were found to be the predominant morphology throughout the shell with size variations across the shell thickness. Primary Dendrite Arm Spacing (PDAS) increases by increasing the distance from meniscus or slab surface. Subsequently, a model is proposed to describe the variation of the PDAS with the shell thickness (the distance from slab surface) under solidifiction conditions experienced in the primary cooling zone of thin-slab casting. The proposed relationship related the PDAS to the shell thickness and, hence, can be used as a tool for predicting solidifcation structure and optimizing the thin-slab casting of low alloy steels

    Penelitian kuantitatif korelasional ini bertujuan untuk mengetahui hubungan antara motivasi belajar dengan prokrastinasi akademik. Partisipan berjumlah 100 mahasiswa rantau yang berkuliah di UKSW dengan menggunakan teknik purposive sampling. Instrumen penelitian menggunakan Academic Procrastination Scale dari Tuckman yang telah di uji validitas konstruk di Indonesia oleh Angki dan Academic Motivation Scale dari Deci dan Ryan yang telah di uji validitas konstruk di Indonesia oleh Natalya. Analisis data menggunakan teknik korelasi Product Moment Spearman’s rho menunjukkan hasil koefisien korelasi (rxy) -0.392 dengan nilai sig 0.000 (p<0,05) yang artinya terdapat hubungan negatif yang signifikan antara motivasi belajar dengan prokrastinasi akademik pada mahasiswa rantau yang berkuliah di UKSW. Hal ini menunjukkan bahwa semakin tinggi prokrastinasi akademik maka motivasi belajar akan semakin rendah sebaliknya semakin tinggi motivasi belajar maka prokrastinasi akademik semakin rendah

    Phosphine-free chiral iridium catalysts for asymmetric catalytic hydrogenation of simple ketones

    Get PDF
    Novel pyridylalkylamine and aminopyridinato ligand stabilized iridium complexes with no P ligand are introduced. These complexes have been investigated as catalysts for asymmetric hydrogenation of simple ketones, resulting in an active catalyst for bulky alkyl aryl ketones that is α-methylpropiophenone. The ligands were synthesized from inexpensive starting materials and their modular design allows for the introduction of a broad variety of substitution patterns. Additionally, better activity and selectivity was observed at 20 °C and 20 bar H2 pressure with a catalyst loading as low as 0.05 mol% iridium. These phosphorus free catalysts have always been a central issue in both academic and industrial research

    ABSTRACT This study examines Indonesia's multi-track diplomacy efforts to propose Ijen Geopark as a UNESCO Global Geopark (UGGp) from 2020 to 2023. Located in East Java, Ijen Geopark boasts unique geological wealth, biodiversity, and cultural heritage, including the blue fire phenomenon, the largest acidic crater lake in the world, and the cultural traditions of the Osing Tribe. This research aims to analyze diplomatic strategies that encompass geoheritage aspects, conservation, education, and sustainable management of the area.The research employs a descriptive qualitative approach, utilizing primary data from interviews and secondary data from related literature. The results reveal that Ijen Geopark's geoheritage values— including scientific, educational, aesthetic, and economic aspects—serve as a primary foundation for its multi-track diplomacy. These strategies involve the central and regional governments (Track 1), local community empowerment in geoheritage conservation (Track 4), support from academics through scientific research and education (Track 5), and promotion through traditional and digital media (Track 9).The success of these efforts is reflected in the official recognition of Ijen Geopark as a UNESCO Global Geopark in 2023. This study confirms that the multi-track diplomacy approach, integrated with geoheritage management, effectively supports international recognition while promoting sustainable development. This recognition not only elevates Ijen Geopark's global profile but also enhances local community welfare through geotourism development. Keywords: Ijen Geopark, UNESCO Global Geopark, geoheritage, multi-track diplomacy

    Towards optimal use of antithrombotic therapy of people with cancer at the end of life: A research protocol for the development and implementation of the SERENITY shared decision support tool

    Anticoagulants; Hemorrhage; ThrombosisAnticoagulantes; Hemorragia; TrombosisAnticoagulants; Hemorràgia; TrombosiBackground Even though antithrombotic therapy has probably little or even negative effects on the well-being of people with cancer during their last year of life, deprescribing antithrombotic therapy at the end of life is rare in practice. It is often continued until death, possibly resulting in excess bleeding, an increased disease burden and higher healthcare costs. Methods The SERENITY consortium comprises researchers and clinicians from eight European countries with specialties in different clinical fields, epidemiology and psychology. SERENITY will use a comprehensive approach combining a realist review, flash mob research, epidemiological studies, and qualitative interviews. The results of these studies will be used in a Delphi process to reach a consensus on the optimal design of the shared decision support tool. Next, the shared decision support tool will be tested in a randomised controlled trial. A targeted implementation and dissemination plan will be developed to enable the use of the SERENITY tool across Europe, as well as its incorporation in clinical guidelines and policies. The entire project is funded by Horizon Europe. Results SERENITY will develop an information-driven shared decision support tool that will facilitate treatment decisions regarding the appropriate use of antithrombotic therapy in people with cancer at the end of life. Conclusions We aim to develop an intervention that guides the appropriate use of antithrombotic therapy, prevents bleeding complications, and saves healthcare costs. Hopefully, usage of the tool leads to enhanced empowerment and improved quality of life and treatment satisfaction of people with advanced cancer and their care givers
