Resumo:

AbstractTwo different samples of Ce3Rh4Ge4were synthesized from different starting compositions by melting of the elements in an arc-melting furnace followed by annealing sequences in a sealed tantalum ampoule in a muffle furnace. The structures of two different stacking variants were refined on the basis of temperature dependent single-crystal X-ray diffractometer data. At high temperature Ce3Rh4Ge4adopts the U3Ni4Si4type structure with strongly enhanced anisotropic displacement parameters for the Rh1 atoms. For the two different crystals, additional reflections start to appear at different temperatures. The first crystal showed additional reflections already at room temperature (stacking variant I) and the second one showed additional reflections emerging below 270 K (stacking variant II). Stacking variant I could be described with the (3+1)D superspace groupI2/m(α0γ)00;α=1/2a*,γ=1/2c*; (Z=2), 1252F2values, 48 variables, wR=0.0306 for the main and wR=0.0527 for 440 1storder satellite reflections, similar to Pr3Rh4Ge4. For stacking variant II the (3+1)D superspace group isImmm(α00)00s;α=1/2a*; (Z=2). The structure could be refined with 1261F2values, 53 variables and residuals ofwR=0.0331 for the main reflections andwR=0.1755 (R1obs=0.0788) for the 1storder satellite reflections, [a=406.2(1),b=423.7(1) andc=2497.1(1) pm]. The commensurate description could be transformed to a three-dimensional (3D) supercell with space groupPnmaandZ=4:a=812.5(1),b=423.7(1),c=2497.1(2) pm, 1261F2values, 69 variables andwR=0.0525. The relation of the U3Ni4Si4type structure, the (3+1)D modulated and the 3D supercells are discussed on the basis of group-subgroup schemes. Ab initio electronic structure calculations are in line with the diffraction experiments, revealing the lowest total energy for thePnmaphase.

In experiments with winter rape during 2004–2008, we examined the effectiveness of fungicides containing active ingredients based upon triazoles and SBI inhibitors (group A): flusilazole 250 g/l a.i., flusilazole 125 g/l a.i. + carbendazim 250 g/l a.i., and cyproconazole 120 g/l a.i. + carbendazim 300 g/l a.i. Fungicides based upon older and newer triazoles, strobilurins, and SDH inhibitors (group B) were also used: cyproconazole 80g/l a.i. + azoxystrobin 200 g/l a.i., prothioconazole 250 g/l a.i., prothioconazole 125 g/l a.i. + tebuconazole 125 g/l a.i., and boscalid 200 g/l a.i. + dimoxystrobin 200 g/l a.i. The application of group A fungicides against S. sclerotiorum during BBCH 65-69 growth stage had demonstratively higher effectiveness, while for group B the application date had no effect. The greening (or “stay-green”) effect only occurred with group B. The correlation coefficient for greening effect and yield was R = −0.3033 for applications during BBCH 61-65 while it was R= −0.3542 for BBCH 65-69 stage, thus indicating a relatively weak relationship.

Resumo:

High pressure (HP) treatment affects many constituents of milk (for reviews see Huppertz et al. 2002; Needs, 2002); particular in the properties of casein micelles in HP-treated milk differ considerably from their counterparts in untreated milk. In milk treated at 100–200 MPa, average casein micelle size differs little from that of untreated milk (Needs et al. 2000a; Huppertz et al. 2004a; Regnault et al. 2004; Anema et al. 2005), but micelle size in milk treated at 250 MPa for [ges ]15 min is considerably higher than in untreated milk, probably due to HP-induced aggregation of casein micelles (Huppertz et al. 2004a,b; Regnault et al. 2004); after treatment at 300–800 MPa, micelle size is ~50% lower than that in untreated milk (Needs et al. 2000a; Huppertz et al. 2004a,b; Anema et al. 2005). HP-induced changes in average casein micelle size are irreversible on subsequent storage, except for the increase in micelle size after treatment at 250 MPa (Huppertz et al. 2004a).

Resumo:

We investigated the effect of beta-alanine (BA) alone (study A) and in combination with sodium bicarbonate (SB) (study B) on 100- and 200-m swimming performance. In study A, 16 swimmers were assigned to receive either BA (3.2 g·day−1 for 1 week and 6.4 g·day−1 for 4 weeks) or placebo (PL; dextrose). At baseline and after 5 weeks of supplementation, 100- and 200-m races were completed. In study B, 14 were assigned to receive either BA (3.2 g·day−1 for 1 week and 6.4 g·day−1 for 3 weeks) or PL. Time trials were performed once before and twice after supplementation (with PL and SB), in a crossover fashion, providing 4 conditions: PL-PL, PL-SB, BA-PL, and BA-SB. In study A, BA supplementation improved 100- and 200-m time-trial performance by 2.1% (p = 0.029) and 2.0% (p = 0.0008), respectively. In study B, 200-m time-trial performance improved in all conditions, compared with presupplementation, except the PL-PL condition (PL-SB, +2.3%; BA-PL, +1.5%; BA-SB, +2.13% (p < 0.05)). BA-SB was not different from BA-PL (p = 0.21), but the probability of a positive effect was 78.5%. In the 100-m time-trial, only a within-group effect for SB was observed in the PL-SB (p = 0.022) and BA-SB (p = 0.051) conditions. However, 6 of 7 athletes swam faster after BA supplementation. The probability of BA having a positive effect was 65.2%; when SB was added to BA, the probability was 71.8%. BA and SB supplementation improved 100- and 200-m swimming performance. The coingestion of BA and SB induced a further nonsignificant improvement in performance.

Trabalho de projeto de mestrado, Educação (Tecnologias de Informação e Comunicação na Educação), Universidade de Lisboa, Instituto de Educação, 2012
Este projeto teve por objetivo avaliar as perceções de 167 docentes em relação a uma ação de formação online realizada em contexto de formação contínua de professores A ação de formação, creditada com o título “Conhecimento Distribuído com a Web 2.0” com a duração de 50 horas, com uma componente presencial de 9 horas, e uma componente a distância equivalente a 41 horas foi realizada em regime de blended learning. Esta ação foi concebida com o objetivo de criar materiais didáticos em formato digital, para organização e partilha de informação e criação de conhecimento e de autoformação por parte dos docentes. Foi construído um ambiente de aprendizagem suportado na plataforma de comunicação Ning. No fim de cada ação foi aplicado um questionário de avaliação e analisados os relatórios críticos acerca das diversas dimensões do curso, que constituíram a base para este estudo, que se situa num paradigma de estudo misto. As dimensões avaliadas foram 1) design da plataforma, 2) estratégias e atividades, 3) conteúdos e materiais, 4) gestão do tempo, 5) tutoria, 6) interação online, 7) atitude em relação ao ensino online e 8) disponibilidade para frequentar o ensino online. Este estudo foi ainda desenvolvido no que diz respeito ao conceito de satisfação dos docentes com a formação, relacionando-o com a relevância dos conhecimentos e competências adquiridos para a alteração das práticas profissionais e a visibilidade da atividade dos docentes junto a comunidade escolar. Os resultados obtidos revelam que os docentes têm perceções bastante positivas sobre a aprendizagem online, regime que consideram adequado à atual realidade da profissão docente e que, no futuro, preferem optar por ações de formação em regime de blended learning. Futuros desenvolvimentos deste estudo implicam o alargamento da amostra, para determinar relações mais precisas entre as variáveis.
This study aimed at assessing the perceptions of 167 teachers about an online training course involving teachers from 20 Schools of Sesimbra, Setúbal and Palmela counties. The course, called "Distributed Knowledge with Web 2.0", was officially certified as a blended learning modality, with the duration of 50 hours, 41 of which occurred online. This blended learning course was designed at producing educational materials in digital format, and included autonomous and collaborative activities, for knowledge sharing and building. A learning environment, supported by the Ning platform, was set up. At the end of the course, the trainees answered to a pencil and paper survey, which was the basis for this research, in order to evaluate the course dimensions such as 1) the platform design, 2) strategies and activities, 3) contents and materials, 4) time management, 5) online tutoring, 6) online interaction, 7) attitudes towards online learning, and 8) the trainees’ intentions to enroll in future online courses. The trainees’ satisfaction with the course, derived from the acquired knowledge and skills relevance, the new teaching and learning practices and their visibility in the school community. Furthermore, the results show that teachers who attended this training disclosed very positive perceptions about online learning, a modality they consider adequate to their current professional status and conditions. The trainees also showed their intention of, in the future, opting for blended training arrangements. Future developments of this study involve a larger sample, in order to establish more accurate relationships among the researched variables.

Através do estudo de oito filmes de Cecil B. DeMille (1881-1959), não descurando breves intromissões históricas em outras películas, pretendemos analisar as formas propostas pelo realizador para representar filmicamente a Antiguidade Clássica e a Idade Média, na primeira metade do século XX, no âmbito do cinema produzido em Hollywood. Deixando transparecer um gosto evidente pela manipulação de múltiplas tradições (literárias, pictóricas, teatrais, operáticas), DeMille apropriou-se de uma teia complexa de fontes que contribuíram para diversificar a linguagem cinematográfica e, na perspectiva apresentada neste estudo, a transformaram num cadinho de elementos, processos e mecanismos de afirmação da Cultura Contemporânea Ocidental.
Through the study of eight films of Cecil B. DeMille (1881-1959), not avoiding brief historical intermezzi in other movies, we analyze the forms proposed by the director to represent the Classical Antiquity and the Middle Ages in his work, throughout the first half of the twentieth century, in the context of Hollywood productions. Showing a preference for the manipulation of multiple traditions (literary, pictorial, dramatic, operatic), DeMille adopted a complex web of sources that contributed to diversify film language and, in the perspective presented in this study, transformed it into an amalgam of elements, processes, and mechanisms of affirmation of Western Contemporary Culture.

<b>This book explores marijuana from a variety of angles, including its impacts on the brain and body, potential for abuse, and legal status. Relying on science rather than sensationalism, it answers young readers' most pressing questions about this controversial drug.</b> In 2022, medical marijuana is legal in 37 states and recreational marijuana is legal in 18, yet the drug remains illegal at the federal level. Public opinion on marijuana has changed substantially in the last 20 years, and today many young people view the drug as benign or even beneficial. But how exactly does marijuana affect the body and mind, and what are the potential risks of abuse or addiction? Books in Greenwood's <b>Q&A Health Guides</b> series follow a reader-friendly question-and-answer format that anticipates readers' needs and concerns. Prevalent myths and misconceptions are identified and dispelled, and a collection of case studies illustrate key concepts and issues through relatable stories and insightful recommendations. Each book also includes a section on health literacy, equipping teens and young adults with practical tools and strategies for finding, evaluating, and using credible sources of health information both on and off the internet—important skills that contribute to a lifetime of healthy decision-making.

Abstract This book chapter briefly takes a historical view of the major steps in bacterial systematics leading to the first reconciliation workshop in 1987 and a re-evaluation of the species concept in 2002. New challenges and concepts developed since then will be outlined. Never before has the future of the prokaryotic taxonomy been at such a critical point. The uncertain future, and whether Plan A or Plan B will prevail, depends totally on the wisdom of the ICSP. Perhaps by the time this book is published the situation will have been clarified, but the current situation is as full of uncertainty as of excitement, and none of the scenarios can be predicted. In April 2020, a majority of the ICSP members decided to reject the proposals to use DNA as type material. Therefore, this rejection leaves the only path for microbial ecologists to go through Plan B. Only time will reveal whether this was the best decision for the future of the taxonomy for prokaryotes.

Resumo:

Chapter 9 by M. G. Tertr and B. Saveyn provides an estimate of the investment needs and additional costs of bringing the EU’s dependence on fossil fuels from Russia to zero by 2027, with a specific focus on natural gas. This analysis was used to prepare the REPowerEU plan presented by the Commission on the 18th of May 2022. Decoupling the EU from Russian fossil fuel imports has already begun and will pass through various stages affecting both demand and supply. From this perspective, the analysis indicates that implementing the full potential to reach zero-dependence could require 300 billion euros cumulative from now to 2030—which is beyond the Fit for 55 proposal. By the end of 2027, this transition could correspond to approximately 210 billion euros in investment. These REPowerEU investments correspond to about 5% of the total Fit for 55 investments up to 2030 and would come in addition to them. The Commission analysis estimates that the Fit for 55 and REPowerEU measures combined could save the EU 80 billion euros annually on gas imports, 12 billion euros on oil imports, and 1.7 billion euros on coal imports.

Objetivo: estudar as respostas de diferentes fontes comerciais e doses de fósforo no desenvolvimento inicial de cafeeiros. Métodos: O experimento foi desenvolvido em Latossolo Vermelho seguindo delineamento blocos ao acaso, avaliando seis tratamentos constituídos a partir da combinação de dois produtos comerciais: P (49% P2O5) e T (28% P2O5) e três doses: 56, 84 e 129 g m-1 e T: 100, 150 e 200 g m-1, respectivamente. Aos 6 e 11 meses após o transplantio ou emergência foram tomadas medidas das alturas das plantas, e após 15 meses foram realizadas análises dos teores de clorofila e foliares. Resultados: Nos períodos avaliados, 04/06/2022 e 15/11/2022 não foram observados efeitos dos produtos ou doses testadas no crescimento dos cafeeiros. Em março de 2023 não foram observados efeitos dos produtos na nutrição foliar dos cafeeiros. Todavia, foram observados maiores valores do índice de clorofila b utilizando o produto T, ou seja, esse produto comercial, em qualquer dose, elevou os teores de clorofila B. Conclusão: As fontes e doses de fósforo influenciaram apenas os teores da clorofila B.

The aim of this article is: (a) to give the definition of adaptive hypermedia (AH) and state what AH means, and (b) to explore the role of AH in education at this digital age, in which the majority of learners are generally digitally fluent and competitive (Turel 2015b, Gros et al., 2012, pp. 190-210) although some claims otherwise (Bullen, Morgan & Qayyum, 2011, pp. 1-24). Pedagogically and epistemologically, educational institutions (i.e. nursery, primary, secondary and high schools, colleges, vocational schools and colleges, life-long learning centres, adult education centres, and universities) should respond to such learning demands and differences to accommodate the digital-literate, wise and efficient learning style preferences of today's learners by providing AH learning materials for them. More frankly, educational institutions have to use and provide AH learning materials for their learners in order to be competitive in this digital age (Turel, 2014a; Türel, 2013; Duncan-Howell, 2012).

A basic task of machine learning and data mining is to automatically uncover <b>patterns</b> that reflect regularities in a data set. When dealing with a large database, especially when domain knowledge is not available or very weak, this can be a challenging task. The purpose of <b>pattern discovery</b> is to find non-random relations among events from data sets. For example, the “exclusive OR” (XOR) problem concerns 3 binary variables, A, B and C=A<img src="http://resources.igi-global.com/Marketing/Preface_Figures/x_symbol.png">B, i.e. C is true when either A or B, but not both, is true. Suppose not knowing that it is the XOR problem, we would like to check whether or not the occurrence of the compound event [A=T, B=T, C=F] is just a random happening. If we could estimate its frequency of occurrences under the random assumption, then we know that it is not random if the observed frequency deviates significantly from that assumption. We refer to such a compound event as an event association pattern, or simply a <b>pattern</b>, if its frequency of occurrences significantly deviates from the default random assumption in the statistical sense. For instance, suppose that an XOR database contains 1000 samples and each primary event (e.g. [A=T]) occurs 500 times. The expected frequency of occurrences of the compound event [A=T, B=T, C=F] under the independence assumption is 0.5×0.5×0.5×1000 = 125. Suppose that its observed frequency is 250, we would like to see whether or not the difference between the observed and expected frequencies (i.e. 250 – 125) is significant enough to indicate that the compound event is not a random happening.<div><br></div><div>In statistics, to test the correlation between random variables, <b>contingency table</b> with chi-squared statistic (Mills, 1955) is widely used. Instead of investigating variable correlations, pattern discovery shifts the traditional correlation analysis in statistics at the variable level to association analysis at the event level, offering an effective method to detect statistical association among events.</div><div><br></div><div>In the early 90’s, this approach was established for second order event associations (Chan & Wong, 1990). A higher order <b>pattern discovery</b> algorithm was devised in the mid 90’s for discrete-valued data sets (Wong & Yang, 1997). In our methods, patterns inherent in data are defined as statistically significant associations of two or more primary events of different attributes if they pass a statistical test for deviation significance based on <b>residual analysis</b>. The discovered high order patterns can then be used for classification (Wang & Wong, 2003). With continuous data, events are defined as Borel sets and the pattern discovery process is formulated as an optimization problem which recursively partitions the sample space for the best set of significant events (patterns) in the form of high dimension intervals from which probability density can be estimated by Gaussian kernel fit (Chau & Wong, 1999). Classification can then be achieved using Bayesian classifiers. For data with a mixture of discrete and continuous data (Wong & Yang, 2003), the latter is categorized based on a global optimization discretization algorithm (Liu, Wong & Yang, 2004). As demonstrated in numerous real-world and commercial applications (Yang, 2002), pattern discovery is an ideal tool to uncover subtle and useful patterns in a database. </div><div><br></div><div>In pattern discovery, three open problems are addressed. The first concerns learning where noise and uncertainty are present. In our method, noise is taken as inconsistent samples against statistically significant patterns. Missing attribute values are also considered as noise. Using a standard statistical <b>hypothesis testing</b> to confirm statistical patterns from the candidates, this method is a less ad hoc approach to discover patterns than most of its contemporaries. The second problem concerns the detection of polythetic patterns without relying on exhaustive search. Efficient systems for detecting monothetic patterns between two attributes exist (e.g. Chan & Wong, 1990). However, for detecting polythetic patterns, an exhaustive search is required (Han, 2001). In many problem domains, polythetic assessments of feature combinations (or higher order relationship detection) are imperative for robust learning. Our method resolves this problem by directly constructing polythetic concepts while screening out non-informative pattern candidates, using statisticsbased heuristics in the discovery process. The third problem concerns the representation of the detected patterns. Traditionally, if-then rules and graphs, including networks and trees, are the most popular ones. However, they have shortcomings when dealing with multilevel and multiple order patterns due to the non-exhaustive and unpredictable hierarchical nature of the inherent patterns. We adopt <b>attributed hypergraph</b> (AHG) (Wang & Wong, 1996) as the representation of the detected patterns. It is a data structure general enough to encode information at many levels of abstraction, yet simple enough to quantify the information content of its organized structure. It is able to encode both the qualitative and the quantitative characteristics and relations inherent in the data set.<br></div>

A simple, robust and for the quantification of experimentally 20 related impurities of sulfamethoxazole (SM) and trimethoprim (TM) in liquid pharmaceutical dosage form, a novel RP-HPLC method was developed. Utilizing gradient elution on a Kromasil 100-5-C18; 5.0 m, (4.0x250) mm, column, chromatographic separation was accomplished. Solvent A (solution of 0.08% orthophosphoric acid in water) and Solvent B (mixture of acetonitrile and methanol, 80:20 v/v), given at a flow rate of 0.8 ml/min, respectively, make up the mobile phase. Using a photodiode array (PDA) detector, the analytes were identified and measured at 210 nm. Eight Sulfamethoxazole-related impurities and twelve Trimethoprim-related impurities can be quantified and evaluated using an organic impurities technique. According to the ingredients of the injection dosage form, the LOQ Standard solution concentration for Sulfamethoxazole Impurities is 0.0016 mg/mL and for Trimethoprim Impurities is 0.00032 mg/mL. For the OI process, the sample’s nominal concentrations of trimethoprim and sulfamethoxazole are 0.32 mg/mL and 1.6 mg/mL, respectively. The Validation range of the procedure was examined for test concentrations ranging from 0.1% to 1.0%. For all the stated contaminants, LOQ solution and LOQ spiked sample solution are stable for 24 hours at 5 °C sample temperature. At a sample temperature of 5°C, Trimethoprim EP Impurity-H is stable for up to 12 hours. According to ICH recommended guidelines, the method was validated, and it proved to be accurate and exact (repeatability and intermediate precision level) within the corresponding linear range of known SM and TM impurities.

Education is one of the most important signs of social progress and throughout the years a twofold evolution has taken place: on the one hand, the providers of knowledge have evolved from schools and universities to the business community and on the other hand, the traditional receivers of knowledge have changed into creators of knowledge. Business organizations have become aware that the corporate involvement in the community by implementing social campaigns on education may trigger a higher degree of visibility and consolidate the stakeholder relationship management. Thus the well-known corporate social responsibility (CSR) syntagm, ?doing well by doing good? (Rawlins, 2005) has turned into a pervasive element of the organizational discourse. As the report on CSR of the European Commission and the Directorate-General for Employment, Social Affairs and Inclusion (2011) highlighted, CSR should not be ?an isolated practice or teaching subject but a cross-cutting approach embedded in the wider concept of sustainable development?. The economic, legal, ethical, and philanthropic dimensions beyond every CSR activity should be integrated within the framework of campaigns which ?are often driven by reform efforts, actions that seek to make life or society or both better, as defined by emerging social values? (Dozier et. al, 2001). The final outcome of improving people?s life and/ or society involves stirring one?s awareness towards an issue. Investing into people?s education has become a pervasive issue for many organizations nowadays and non-formal education is a type of acquiring knowledge which the business community seems to prefer because it lies on social constructivism whose purposes are self-knowledge, development of identities, and belief that stakeholders can make a difference in the world (Oldfather et al., 1999). Within the age of Web 2.0 the traditional non-formal learning settings (museums, zoos, botanical gardens, planetariums and so on) have changed into online environments where features such as engaging, participating, connecting, collaborating, and sharing (Lee, Williams, Kim, 2012) prevail. Running a CSR 2.0 campaign on non-formal education implies that business organizations create these virtual environments where social media applications are used as a bidirectional information delivery system where stakeholders play an active role in the collaborative knowledge construction. As methodology, we will use the framing theory in order to provide the content analysis of the CSR 2.0 campaigns on non-formal education which were awarded at the Romanian PR Award in 2009, 2010 and 2011. Frames rely on the selection of some aspects of a perceived reality which are made more salient in a communicating (e-)text. We will provide a threefold analysis: a) a general framework of the Romanian CSR 2.0 campaigns on non-formal education taking into account R. Entman?s four frame types: problem definition, causal interpretation, moral evaluation and treatment recommendation; b) a structural analysis of non-formal education virtual environments as a hybrid genre formed of multimodal resources; c) a comparative analysis of the online environments framed as treatment recommendations which were used in the awarded Romanian CSR 2.0 campaigns on education. The research questions will focus on four aspects: the salience of business organizations as providers of non-formal education; the dominance of the awarded thematic online environments; the types of social actions framed in the different thematic e-learning environments; the types of digital identities virtually assigned to stakeholders.

This study explored spatial patterns of overflights at Badlands National Park (BADL). Overflights were analyzed from July 13, 2022 to August 27, 2022 (46 days) using Automatic Dependent Surveillance-Broadcast (ADS-B) data. There were 26 days of data and 20 days of missing data due to technical difficulties with the ADS-B logger. The first phase of analysis focused on all overflights and found overflights above most areas of BADL. The second phase of analysis focused on low-level overflights that fly below 7,000ft mean sea level (MSL) and fly within 10-miles of the BADL boundary, which found a concentration of flights between 4,000 - 7,000 feet MSL near the eastern boundary of BADL. The third phase of analysis removed all overflights known not to be air tours. Figures were produced that display all the flights of the cleaned dataset, waypoints across AGL altitudes, waypoints across MSL altitudes, flightpaths for fixed wing single engine, flightpaths for rotorcraft, flight paths for fixed wing multi engine, and flightpaths for specific air tour operators. This information can be used for planning and management purposes and this study serves as a resource for future research.

Development projects have a wider set of impacts than just direct project outputs. A hydropower dam, for example, produces electricity but also disrupts river flows and may affect biodiversity and the general aquatic environment. A new port development may affect coastal resources such as mangroves and coral reefs. Coal-fired power plants affect both the local and the global environments through emissions of ash and dust (affecting mostly the local environment) as well as greenhouse gases (affecting the global environment). Sewage and sanitation projects provide new services to consumers but also change the quantity and quality of wastewater released into the environment. An enhanced economic analysis allows this wider range of impacts -both benefits and costs- to be taken into account. This approach follows the IDB's operational directives (OP 703, Directives B.5 and B.9) and is explained in an IDB Technical Note IDB-TN-428 (Dixon, 2012). This paper builds upon existing analyses of four recent IDB projects to apply this approach. The projects selected for this study deal with the water sector and range in monetary value from US$9.5 million (Guyana) to US$246.5 million (Trinidad and Tobago), with Paraguay (US$20 million) and Uruguay (US$118.6 million) in between.

Background An estimated 292 million people are living with chronic hepatitis B virus (HBV) infection globally, including 223,000 people in Australia. HBV diagnosis and linkage of people living with HBV to clinical care is suboptimal in Australia, with 27% of people living with HBV undiagnosed and 77% not receiving regular HBV clinical care. This systematic review aimed to characterize population-level interventions implemented to enhance all components of HBV care cascade and analyse the effectiveness of interventions. Review questions Question 1: What population-level interventions, programs or policy approaches have been shown to be effective in reducing the incidence of hepatitis B; and that may not yet be fully rolled out or evaluated in Australia demonstrate early effectiveness, or promise, in reducing the incidence of hepatitis B? Question 2: What population-level interventions and/or programs are effective at reducing disease burden for people in the community with hepatitis B? Methods Four bibliographic databases and 21 grey literature sources were searched. Studies were eligible for inclusion if the study population included people with or at risk of chronic HBV, and the study conducted a population-level interventions to decrease HBV incidence or disease burden or to enhance any components of HBV care cascade (i.e., diagnosis, linkage to care, treatment initiation, adherence to clinical care), or HBV vaccination coverage. Studies published in the past 10 years (since January 2012), with or without comparison groups were eligible for inclusion. Studies conducting an HBV screening intervention were eligible if they reported proportion of people participating in screening, proportion of newly diagnosed HBV (participant was unaware of their HBV status), proportion of people received HBV vaccination following screening, or proportion of participants diagnosed with chronic HBV infection who were linked to HBV clinical care. Studies were excluded if study population was less than 20 participants, intervention included a pharmaceutical intervention or a hospital-based intervention, or study was implemented in limited clinical services. The records were initially screened by title and abstract. The full texts of potentially eligible records were reviewed, and eligible studies were selected for inclusion. For each study included in analysis, the study outcome and corresponding 95% confidence intervals (95%CIs) were calculated. For studies including a comparison group, odds ratio (OR) and corresponding 95%CIs were calculated. Random effect meta-analysis models were used to calculate the pooled study outcome estimates. Stratified analyses were conducted by study setting, study population, and intervention-specific characteristics. Key findings A total of 61 studies were included in the analysis. A large majority of studies (study n=48, 79%) included single-arm studies with no concurrent control, with seven (12%) randomised controlled trials, and six (10%) non-randomised controlled studies. A total of 109 interventions were evaluated in 61 included studies. On-site or outreach HBV screening and linkage to HBV clinical care coordination were the most frequent interventions, conducted in 27 and 26 studies, respectively. Question 1 We found no studies reporting HBV incidence as the study outcome. One study conducted in remote area demonstrated that an intervention including education of pregnant women and training village health volunteers enhanced coverage of HBV birth dose vaccination (93% post-intervention, vs. 81% pre-intervention), but no data of HBV incidence among infants were reported. Question 2 Study outcomes most relevant to the HBV burden for people in the community with HBV included, HBV diagnosis, linkage to HBV care, and HBV vaccination coverage. Among randomised controlled trials aimed at enhancing HBV screening, a meta-analysis was conducted including three studies which implemented an intervention including community face-to-face education focused on HBV and/or liver cancer among migrants from high HBV prevalence areas. This analysis demonstrated a significantly higher HBV testing uptake in intervention groups with the likelihood of HBV testing 3.6 times higher among those participating in education programs compared to the control groups (OR: 3.62, 95% CI 2.72, 4.88). In another analysis, including 25 studies evaluating an intervention to enhance HBV screening, a pooled estimate of 66% of participants received HBV testing following the study intervention (95%CI: 58-75%), with high heterogeneity across studies (range: 17-98%; I-square: 99.9%). A stratified analysis by HBV screening strategy demonstrated that in the studies providing participants with on-site HBV testing, the proportion receiving HBV testing (80%, 95%CI: 72-87%) was significantly higher compared to the studies referring participants to an external site for HBV testing (54%, 95%CI: 37-71%). In the studies implementing an intervention to enhance linkage of people diagnosed with HBV infection to clinical care, the interventions included different components and varied across studies. The most common component was post-test counselling followed by assistance with scheduling clinical appointments, conducted in 52% and 38% of the studies, respectively. In meta-analysis, a pooled estimate of 73% of people with HBV infection were linked to HBV clinical care (95%CI: 64-81%), with high heterogeneity across studies (range: 28-100%; I-square: 99.2%). A stratified analysis by study population demonstrated that in the studies among general population in high prevalence countries, 94% of people (95%CI: 88-100%) who received the study intervention were linked to care, significantly higher than 72% (95%CI: 61-83%) in studies among migrants from high prevalence area living in a country with low prevalence. In 19 studies, HBV vaccination uptake was assessed after an intervention, among which one study assessed birth dose vaccination among infants, one study assessed vaccination in elementary school children and 17 studies assessed vaccination in adults. Among studies assessing adult vaccination, a pooled estimate of 38% (95%CI: 21-56%) of people initiated vaccination, with high heterogeneity across studies (range: 0.5-93%; I square: 99.9%). A stratified analysis by HBV vaccination strategy demonstrated that in the studies providing on-site vaccination, the uptake was 78% (95%CI: 62-94%), significantly higher compared to 27% (95%CI: 13-42%) in studies referring participants to an external site for vaccination. Conclusion This systematic review identified a wide variety of interventions, mostly multi-component interventions, to enhance HBV screening, linkage to HBV clinical care, and HBV vaccination coverage. High heterogeneity was observed in effectiveness of interventions in all three domains of screening, linkage to care, and vaccination. Strategies identified to boost the effectiveness of interventions included providing on-site HBV testing and vaccination (versus referral for testing and vaccination) and including community education focussed on HBV or liver cancer in an HBV screening program. Further studies are needed to evaluate the effectiveness of more novel interventions (e.g., point of care testing) and interventions specifically including Indigenous populations, people who inject drugs, men who have sex with men, and people incarcerated.

Seton Lake is a freshwater fiord located in southwestern British Columbia, roughly 4 km west of Lillooet and 250 km north-northeast of Vancouver. Located in the Coast Mountains, it is an alpine lake about 22-km long and roughly 1-1.5 km wide. It is separated from nearby Anderson Lake, located to the west, by a large pre-historic rock avalanche deposit at Seton Portage. The lake stands at about 243 m above sea level and is up to about 150 m deep (BC gov., 1953). Water level is controlled by a hydroelectric dam (i.e., Seton dam) located at the eastern end of the lake. Here, the lake drains east into Seton Canal, a 5 km diversion of the flow of the Seton River, which begins at the Seton dam. The Seton Canal pushes water to the Seton Powerhouse, a hydroelectric generating station at the Fraser River, just south of the community of Sekw'el'was and confluence of the Seton River, which drains into the Fraser River at Lillooet. Seton Portage, Shalatlh, South Shalatlh, Tsal'alh (Shalath), Sekw'el'was (Cayoosh Creek), and T'it'q'et (Lillooet) are communities that surround the lake. Surrounded by mountainous terrain, the lake is flanked at mid-slope by glacial and colluvial sediments deposited during the last glacial and deglacial periods (Clague, 1989; Jakob, 2018). The bedrock consists mainly of mafic to ultramafic volcanic rocks with minor carbonate and argillite from the Carboniferous to Middle Jurassic periods (Journeay and Monger, 1994). As part of the Public Safety Geoscience Program at the Geological Survey of Canada (Natural Resources Canada), our goal is to provide baseline geoscience information to nearby communities, stakeholders and decision-makers. Our objective was to see what kind of sediments were deposited and specifically if we could identify underwater landslide deposits. Thus, we surveyed the lake using a Pinger SBP sub bottom profiler made by Knudsen Engineering Ltd., with dual 3.5 / 200 kHz transducers mounted to a small boat (see photo). This instrument transmits sound energy down through the water column that reflects off the lake bottom surface and underlying sediment layers. At the lake surface, the reflected sound energy is received by the profiler, recorded on a laptop computer, and integrated with GPS data. These data are processed to generate a two-dimensional image (or profile) showing the character of the lake bottom and underlying sediments along the route that the boat passed over. Our survey in 2022 recorded 98 profiles along Seton Lake. The red transect lines show the locations of the 20 profiles displayed on the poster. The types of sediments observed are mostly fine-grained glaciolacustrine sediments that are horizontally bedded with a subtle transition between glaciolacustrine to lacustrine (e.g., profiles A-A'; C-C'; F-F'; S-S'). Profile S-S' displays this transition zone. The glaciolacustrine sediments probably were deposited as the Cordilleran Ice Sheet retreated from the local area (~13,000-11,000 years ago; Clague, 2017) and the lacustrine sediments, after the ice receded to present-day conditions. Some of the parallel reflections are interrupted, suggesting abrupt sedimentation by deposits that are not horizontally bedded; these are interpreted as landslide deposits (see pink or blue deposits on profiles). The deposits that show disturbance in the sedimentation found within the horizontal beds are thought to be older landslides (e.g., blue arrows/deposits in profiles C-C'; E-E'; F-F'; G-G'; I-I'; J-J'; K-K'; N-N'; P-P'; Q-Q'; R-R'; T-T'; U-U'), but the ones that are found on top of the horizontally laminated sediments (red arrows/pink deposits), and close to the lake wall, are interpreted to be younger (e.g., profiles B-B'; C-C'; H-H'; K-K'; M-M'; O-O'; P-P'; Q-Q'). At the fan delta just west of Seton dam, where there was no acoustic signal penetration, it is interpreted that the delta failed and brought down coarser deposits at the bottom of the lake (e.g., profiles H-H'; M-M'; and perhaps K-K'). However, these could be glacial deposits, bedrock, or other coarser deposits. Some of the deposits that reflect poor penetration of the acoustic signal, below the glaciolacustrine sediments, could represent glacial deposits, old landslide deposits, or perhaps the presence of gas (orange arrows; e.g, B-B'; D-D'; J-J'; O-O', T-T'). The preliminary results from sub bottom profiling reveal that there are underwater landslides deposits of widely varying ages buried in the bottom of the lake. However, the exact timing of these is not known. Hence our preliminary survey gives an overview of the distribution of landslides where there seems to be a larger number of landslides recorded in the narrower eastern portion of the lake.

Vicksburg National Military Park (VICK) was established for its historical significance as a one of the principle military sieges resulting in a turning point during the American Civil War. The steep terrain around the city of Vicksburg was integral in the military siege, providing high vantage points and a substrate that was easy to entrench for the armies, but unknown to many is the fossil content, particularly a diversity of fossil mollusks. These fossils at VICK are important paleontological resources which have yet to receive focused attention from park staff, visitors, and researchers. The park’s geology is dominated by windblown silt from the last Ice Age which overlays river-transported gravels and bedrock of the late Oligocene–early Miocene-age Catahoula Formation or early Oligocene Vicksburg Group. The park is home to the type section (a geological reference locality upon which a formation is based) for the Mint Spring Formation, one of the most fossiliferous formations in this group (Henderson et al. 2022). Beginning roughly 32 million years ago (Dockery 2019), the early Oligocene deposits of the Vicksburg Group were deposited as the sea level along the Gulf Coast shore repeatedly rose and fell. The eponymously named Vicksburg Group is comprised of, from oldest to youngest, the Forest Hill, Mint Spring, Marianna Limestone, Glendon Limestone, Byram, and Bucatunna Formations. Each of these formations are within VICK’s boundaries, in addition to outcrops of the younger Catahoula Formation. Paleozoic fossils transported by the ancestral Mississippi River have also been redeposited within VICK as pre-loess stream gravels. Overlying these layers is the Quaternary-age silt which composes the loess found throughout VICK, meaning the park’s fossils span the entire Phanerozoic Eon. The fossils of VICK consist mostly of near-shore marine Oligocene invertebrates including corals, bryozoans, bivalves, gastropods, scaphopods, ostracods, and more, though terrestrial and freshwater snails of the loess, microfossils, plant fossils, occasional vertebrates, and others can also be found in the park. Notable historical figures such as Charles Alexandre Lesueur, Charles Lyell, and John Wesley Powell all collected fossils or studied geology in the Vicksburg area. The Vicksburg Group is culturally relevant as well, as the Glendon Limestone Formation has been identified by its embedded fossils as a source rock for Native American effigy pipes. This paleontological resource inventory is the first of its kind for VICK. Although Vicksburg fossils have most recently been studied as part of the Gulf Coast Inventory & Monitoring Network (Kenworthy et al. 2007), the park has never received a comprehensive, dedicated fossil inventory before this report. At least 27 fossil species, listed in Appendix B, have been named and described from specimens collected from within VICK’s lands, and VICK fossils can be found at six or more non-NPS museum repositories. Beginning in January 2022, field surveys were undertaken at VICK, covering nearly all the park’s wooded areas, streams, and other portions beyond the preserved trenches and tour road. Fossils were collected or observed at 72 localities. These specimens will be added into VICK’s museum collections, which previously contained no paleontological resources. Considering the minimal attention dedicated to these resources in the past, these newly acquired fossil specimens may be used in the future for educational, interpretive, or research purposes. Future park construction needs should take into account the protection of these resources by avoiding important localities or allowing collection efforts before localities become inaccessible or lost.
