    Background:  Adolescent pregnancy is associated with major health consequences for adolescent pregnant women including medications and oral health problems such as dental caries and periodontal disease. Pregnancy is a unique state of physical, hormonal, and metabolic changes that can result in an oral cavity imbalance. Changes in salivary components and a decrease in salivary flow rate caused by an increase in progesterone may compromise saliva's protective effects, resulting in dental caries. Objectives: To evaluate dental caries experience in adolescent pregnancy. Method: A sample including 80 pregnant ladies were recruited in this study and categorized into a study group involving 40 primigravida adolescent females aged (15-19)years old and a control group involving 40 primigravida women (20-32) years old who married at age 20 years or more, all of them in the second trimester of pregnancy. Unstimulated salivary samples were collected, salivary flow rate, pH, and dental caries experience were assessed. Saliva samples were analyzed to estimate salivary lactoferrin concentration. Results: The mean (±sd) of decayed surface of the study group was (11.850±0.669) compared to (9.425±1.015) of the control group (p=0.049) and the level of salivary lactoferrin of the study group was (8.071± 0.558) compared to (6.610±0.447)  of the control group (p=0.044), while the mean (±sd) of salivary flow rate of the study group was (0.349±0.020) compared to (0.540±0.157) of the control group (p=0.231) and the mean (±sd) salivary pH was (5.935±0.053) ) compared to (5.995±0.153) of the control group (p=0.712). Conclusion: Adolescent pregnancy is linked to increased dental caries experience by altering salivary characteristics, including lactoferrin levels.

    ABSTRAKPermasalahan sampah merupakan permasalahan yang banyak melibatkan berbagai pihak dalam pengelolaannya terutama di Tempat Pembuangan Akhir (TPA). Salah satu langkah dalam melakukan pengelolaan sampah adalah dengan melakukan identifikasi berbagai permasalahan yang dihadapi pihak pengelola bersama masyarakat sekitar TPA.  Oleh karena itu, Kegiatan Pengabdian ini bertujuan untuk mengidentifikasi tantangan pengelolaan sampah di Tempat Pembuangan Akhir (TPA) Regional Kebon Kongok di Desa Sukamakmur, Lombok Barat. Metode yang digunakan dalam kegiatan ini adalah metode observasi dan wawancara di lokasi TPA. Kegiatan ini banyak melibatkan berbagai pihak terutama pihak pengelola TPA bersama masyarakat sekitar. Berdasarkan kegiatan iniditemukan bahwa distribusi sampah di TPA ini tidak merata, dengan adanya titik-titik kritis dan zona penumpukan sampah yang memerlukan perhatian khusus. Infrastruktur pengelolaan sampah yang terbatas, seperti fasilitas pemrosesan yang kurang, juga menjadi hambatan utama. Dampak lingkungan dan sosial ekonomi dari TPA ini belum sepenuhnya tergambarkan secara rinci, namun ada indikasi dampak sosial ekonomi terhadap masyarakat sekitar. Partisipasi masyarakat dalam program pengelolaan sampah masih rendah, dipengaruhi oleh persepsi negatif terhadap sampah dan ketidakpastian terkait manfaat partisipasi. Sebagai solusi, edukasi dan kesadaran masyarakat menjadi kunci untuk meningkatkan partisipasi. Penyesuaian program dengan konteks lokal dan pemberdayaan masyarakat melalui pendekatan inovatif juga diusulkan. Kata kunci: pengelolaan sampah; tempat pembuangan akhir; analisis data spasial ABSTRACTThe waste problem is a problem that involves many parties in its management, especially at final disposal sites (TPA). One of the steps in managing waste is to identify various problems faced by the management together with the community around the landfill. Therefore, this Community Service Activity aims to identify the challenges of waste management at the Kebon Kongok Regional Final Disposal Site (TPA) in Sukamakmur Village, West Lombok. The method used in this activity is the method of observation and interviews at the landfill location. This activity involves many parties, especially the landfill management and the surrounding community. Based on these activities was found that waste distribution in this landfill is uneven, with critical points and zones of waste accumulation requiring special attention. Limited waste management infrastructure, such as insufficient processing facilities, also poses a major obstacle. The environmental and socio-economic impacts of this landfill have not been fully detailed, but there are indications of socio-economic effects on the surrounding community. Community participation in waste management programs is low, influenced by negative perceptions of waste and uncertainty about the benefits of participation. As a solution, community education and awareness are key to increasing participation. Adjusting programs to local contexts and empowering communities through innovative approaches are also proposed. Keywords: waste management; landfill; spatial data analysi

    The dynamic centres of infrared-dark clouds and the formation of cores

    High-mass stars have an enormous influence on the evolution of the interstellar medium in galaxies, so it is important that we understand how they form. We examine the central clumps within a sample of seven infrared-dark clouds (IRDCs) with a range of masses and morphologies. We use 1-pc-scale observations from the Northern Extended Millimeter Array (NOEMA) and the IRAM 30m telescope to trace dense cores with 2.8-mm continuum, and gas kinematics in C18O, HCO+, HNC, and N2H+ (J = 1–0). We supplement our continuum sample with six IRDCs observed at 2.9 mm with the Atacama Large Millimeter/submillimeter Array (ALMA), and examine the relationships between core- and clump-scale properties. We have developed a fully automated multiple-velocity component hyperfine line-fitting code called MWYDYN which we employ to trace the dense gas kinematics in N2H+ (1–0), revealing highly complex and dynamic clump interiors. We find that parsec-scale clump mass is the most important factor driving the evolution; more massive clumps are able to concentrate more mass into their most massive cores – with a log-normally distributed efficiency of around 9 per cent – in addition to containing the most dynamic gas. Distributions of linewidths within the most massive cores are similar to the ambient gas, suggesting that they are not dynamically decoupled, but are similarly chaotic. A number of studies have previously suggested that clumps are globally collapsing; in such a scenario, the observed kinematics of clump centres would be the direct result of gravity-driven mass inflows that become ever more complex as the clumps evolve, which in turn leads to the chaotic mass growth of their core populations

    Gabriel Harvey and the History of Reading: Essays by Lisa Jardine and others

    Get PDF
    Few articles in the humanities have had the impact of Lisa Jardine and Anthony Grafton’s seminal ‘Studied for Action’ (1990), a study of the reading practices of Elizabethan polymath and prolific annotator Gabriel Harvey. Their excavation of the setting, methods and ambitions of Harvey’s encounters with his books ignited the History of Reading, an interdisciplinary field which quickly became one of the most exciting corners of the scholarly cosmos. A generation inspired by the model of Harvey fanned out across the world’s libraries and archives, seeking to reveal the many creative, unexpected and curious ways that individuals throughout history responded to texts, and how these interpretations in turn illuminate past worlds. Three decades on, Harvey’s example and Jardine’s work remain central to cutting-edge scholarship in the History of Reading. By uniting ‘Studied for Action’ with published and unpublished studies on Harvey by Jardine, Grafton and the scholars they have influenced, this collection provides a unique lens on the place of marginalia in textual, intellectual and cultural history. The chapters capture subsequent work on Harvey and map the fields opened by Jardine and Grafton’s original article, collectively offering a posthumous tribute to Lisa Jardine and an authoritative overview of the History of Reading

    Distributed Ledger Technology (DLT) Applications in Payment, Clearing, and Settlement Systems:A Study of Blockchain-Based Payment Barriers and Potential Solutions, and DLT Application in Central Bank Payment System Functions

    Get PDF
    Payment, clearing, and settlement systems are essential components of the financial markets and exert considerable influence on the overall economy. While there have been considerable technological advancements in payment systems, the conventional systems still depend on centralized architecture, with inherent limitations and risks. The emergence of Distributed ledger technology (DLT) is being regarded as a potential solution to transform payment and settlement processes and address certain challenges posed by the centralized architecture of traditional payment systems (Bank for International Settlements, 2017). While proof-of-concept projects have demonstrated the technical feasibility of DLT, significant barriers still hinder its adoption and implementation. The overarching objective of this thesis is to contribute to the developing area of DLT application in payment, clearing and settlement systems, which is still in its initial stages of applications development and lacks a substantial body of scholarly literature and empirical research. This is achieved by identifying the socio-technical barriers to adoption and diffusion of blockchain-based payment systems and the solutions proposed to address them. Furthermore, the thesis examines and classifies various applications of DLT in central bank payment system functions, offering valuable insights into the motivations, DLT platforms used, and consensus algorithms for applicable use cases. To achieve these objectives, the methodology employed involved a systematic literature review (SLR) of academic literature on blockchain-based payment systems. Furthermore, we utilized a thematic analysis approach to examine data collected from various sources regarding the use of DLT applications in central bank payment system functions, such as central bank white papers, industry reports, and policy documents. The study's findings on blockchain-based payment systems barriers and proposed solutions; challenge the prevailing emphasis on technological and regulatory barriers in the literature and industry discourse regarding the adoption and implementation of blockchain-based payment systems. It highlights the importance of considering the broader socio-technical context and identifying barriers across all five dimensions of the social technical framework, including technological, infrastructural, user practices/market, regulatory, and cultural dimensions. Furthermore, the research identified seven DLT applications in central bank payment system functions. These are grouped into three overarching themes: central banks' operational responsibilities in payment and settlement systems, issuance of central bank digital money, and regulatory oversight/supervisory functions, along with other ancillary functions. Each of these applications has unique motivations or value proposition, which is the underlying reason for utilizing in that particular use case

    Evidence for a dynamic corona in the short-term time lags of black hole X-ray binary MAXI J1820+070

    \ua9 2023 The Author(s) Published by Oxford University Press on behalf of Royal Astronomical Society.In X-ray observations of hard state black hole X-ray binaries (BHXRBs), rapid variations in accretion disc and coronal power-law emission are correlated and show Fourier-frequency-dependent time lags. On short (0.1 s) time-scales, these lags are thought to be due to reverberation and therefore may depend strongly on the geometry of the corona. Low-frequency quasi-periodic oscillations (QPOs) are variations in X-ray flux that have been suggested to arise because of geometric changes in the corona, possibly due to general relativistic Lense-Thirring precession. Therefore, one might expect the short-term time lags to vary on the QPO time-scale. We performed novel spectral-timing analyses on Neutron Star Interior Composition ExploreR observations of the BHXRB MAXI J1820+070 during the hard state of its outburst in 2018 to investigate how the short-term time lags between a disc-dominated and a coronal power-law-dominated energy band vary on different time-scales. Our method can distinguish between variability due to the QPO and broad-band noise, and we find a linear correlation between the power-law flux and lag amplitude that is strongest at the QPO frequency. We also introduce a new method to resolve the QPO signal and determine the QPO phase dependence of the flux and lag variations, finding that both are very similar. Our results are consistent with a geometric origin of QPOs, but also provide evidence for a dynamic corona with a geometry varying in a similar way over a broad range of time-scales, not just the QPO time-scale
