NUMERICAL VALIDATION OF MONOPILE LOADING TEST FOR WIND TURBINE FOUNDATION USING PLAXIS 3-D

This paper presents the verification of a three-dimensional finite element model of full-scale field monopile tests for offshore wind turbine foundations. The results from numerical modeling using PLAXIS 3-D are verified against previously published measured data obtained from optical fiber sensors installed on the internal steel surface of a monopile. The field tests were carried out at a wind farm 200 km from Shanghai and 25 km offshore in the East China Sea. Both vertical and horizontal pile load tests were performed separately on the top of the monopile to investigate soilpile interaction and the pile behavior for the proposed offshore wind farm. The soil is modeled using an elastic – perfectly plastic Mohr-Columb model, while the monopile is modeled using a linear elastic mode. The measured and calculated vertical and horizontal movements, and vertical and horizontal loads along the pile depth are compared. The results of the numerical analysis using the three-dimensional finite element program PLAXIS 3-D are in good agreement with the results of both vertical and horizontal pile loading stages measured from field test results, indicating that the proposed model is suitable for modeling the behavior of axially and laterally loaded monopiles.
RESPONSE OF Gardenia jasminoides PLANTS GROWN ON VARIOUS GROWING MEDIA TO ORGANIC AMENDMENTS

This investigation was conducted during two successive seasons of 2017 and 2018 to evaluate the efficacy of compost tea types prepared from different organic sources including filter mud, spent mushroom compost and vermicompost as well as the most suitable growing media on growth behavior and blooming of gardenia plants. The results showed that all organic fertilizers applied for Gardenia jasminoides plants grown in the mixture of sand and peat moss (1:2v/v) had the best results in comparison with the control plants grown in other growing media. Application of vermicompost tea fertilizer significantly improved all vegetative growth traits i.e. plant height, stem diameter, numbers of branches and leaves as well as increased leaf contents of total chlorophyll and elements of nitrogen, phosphorus and potassium. This reflected on producing flowers with good quality attributes of the plants. The highest populations of total bacteria, fungi and actinomycetes and dehydrogenase activity in the rhizosphere soil were attained by the application of vermicompost tea fertilizer for plants grown in sand and peat moss mixture. Key wrds: Gardenia jasminoides, peat moss, compost tea, NPK Fertilization.
A Rare Case of Herpes Esophagitis in an Immunocompetent Elderly Patient

Herpes esophagitis is common among immunocompromised hosts but is relatively rare among immunocompetent patients. Its symptoms are vague because many different symptoms can be induced by esophageal lesions. Here, we report a case of herpes esophagitis in an elderly immunocompetent patient. A 91-year-old woman visited our community hospital with a complaint of appetite loss for several days. Although she did not have any symptoms of epigastric, oral, or retrosternal pain, multiple ulcers were detected in her esophagus. Biopsy of the edge of the ulcer showed giant cells, indicating a herpes virus infection. She was diagnosed with herpes esophagitis and treated with acyclovir for one week. Her symptoms completely resolved after treatment, and she was discharged. Herpes esophagitis can manifest as vague symptoms in immunocompetent elderly patients. Therefore, herpes esophagitis must be considered in the differential diagnosis of elderly patients presenting with vague symptoms.
Chronic alcohol intake regulates expression of SARS-CoV2 infection-relevant genes in an organ-specific manner

Chronic alcohol consumption and alcohol use disorder (AUD) have a tremendous impact on the patient’s psychological and physiological health. There is some evidence that chronic alcohol consumption influences SARS-CoV2 infection risk, but the molecular mechanism is unknown. Here, we generated expression data of SARS-CoV2 infection relevant genes (Ace2, Tmprss2 and Mas) in different organs in rat models of chronic alcohol exposure and alcohol dependence. ACE2 and TMPRSS2 represent the virus entry point whereas Mas is activating the anti-inflammatory response once the cells are infected. Across three different chronic alcohol test conditions, we found a consistent upregulation of Ace2 in the lung, which is the most affected organ in Covid-19 patients. Other organs such as liver, ileum, kidney, heart, and the brain showed also up-regulation of Ace2 and Mas but in a less consistent manner across the different animal models, while Tmprss2 was unaffected in all conditions. We suggest that alcohol-induced up-regulation of Ace2 can lead to an elevated stochastic probability of cellular virus entry and may thus confer a molecular risk factor for a SARS-CoV2 infection.

Associations between mental illness and non-medical use of prescription opioids among a sample of people who use drugs in Australia and New Zealand

Abstract Non-medical use of prescription opioids (NUPO) is an increasing public health concern in Australia and New Zealand. In response to a lack of research on NUPO in this setting, we investigated the associations between NUPO, mental illnesses, and other substance use, using data from the 2019 Global Drug Survey (GDS). Strategies to reduce NUPO-related harm were also discussed. Socio-demographic characteristics, mental illnesses, NUPO, and other substance use among 2019 GDS respondents were examined. Logistic regression was used to identify factors associated with past year NUPO. Data from 2752 Australian and New Zealand respondents who used drugs were analysed. Pastyear use of heroin, benzodiazepines, cannabis (containing THC), and ecstasy were associated with a greater odds of NUPO, while bipolar disorder managed with medications was associated with a lower odds of NUPO. All other mental illnesses, including co-morbid mental illnesses, were not associated with NUPO after adjusting for potential confounders. Of respondents who reported NUPO and answered secondary questions, 38.8% obtained opioids from a friend or family member. This study provides a unique understanding of potential risk factors for NUPO among people who report mental illness and drug use in Australia and New Zealand, and establishes a basis for future research that is aimed at reducing NUPO-related harm.
Self-Care: An Occupational Therapy Student Perspective

Health professional students, including occupational therapy students, report increasing rates of stress, anxiety, depression, and burnout while completing their academic programs of study. Self-care is one potential solution to this crisis, as engagement in evidence-based self-care practices has been found to improve the health and well-being of various student populations; however, the self-care practices of occupational therapy students have not been well studied. Therefore, this study explored how occupational therapy students understand and practice self-care, and how self-care correlates to perceived stress. Twenty participants engaged in a focus group and completed a 72-hour time diary. Focus group results indicated that participants highly valued their self-care practices, reporting that selfcare improves their well-being, is a skill that must be developed, and plays a critical role in occupational therapy practice. Time diaries revealed that the most frequently recorded self-care occupations were sleeping/napping, meal preparation/eating, and watching television and other streaming services. Total time spent in self-care practices ranged from 9-55 hours, and duration of self-care was not found to correlate with perceived stress or demographic variables. Results demonstrate that the type of self-care activities in which students engage may be more beneficial than duration of self-care alone. Students may benefit from further skill development in self-care to improve their current and future well-being. Occupational therapy educators have the opportunity to assist in developing this skill through intentional programming.
Evaluation of Heat Transfer Effects on Turbocharger Performance

Test data on several small turbochargers with different levels of heat transfer from the turbine to the compressor have been obtained through cooling of the turbocharger center housing and by testing in hot and cold test stands. This data identifies the strong effect of the heat transfer on the apparent efficiency of the compressor and turbine, particularly at low speeds and low mass flows. A simplified theory is used to explain the apparent effect of the heat transfer on the work input and efficiency. The results confirm that conventional performance maps underestimate the efficiency of the compressor stage and overestimate the efficiency of the turbine by as much as 20% points at low speeds. A correction procedure for this effect is defined which converts performance maps obtained with heat transfer to performance maps for adiabatic conditions (for both compressor and turbine) without any prior knowledge or measurement of the heat transfer. The practical significance of the results with regard to turbocharger performance and the relevance to a broader class of turbomachines is discussed.Copyright © 2011 by ASME
A Spiking Neural Network Model of Rodent Head Direction Calibrated With Landmark Free Learning

Maintaining a stable estimate of head direction requires both self motion (ideothetic) information and environmental (allothetic) anchoring. In unfamiliar or dark environments ideothetic drive can maintain a rough estimate of heading but is subject to inaccuracy, visual information is required to stabilise the head direction estimate. When learning to associate visual scenes with head angle, animals do not have access to the ‘ground truth’ of their head direction, and must use egocentrically derived imprecise head direction estimates. We use both discriminative and generative methods of visual processing to learn these associations without extracting explicit landmarks from a natural visual scene, finding all are sufficiently capable at providing corrective signal. Further, we present a spiking continuous attractor model of head direction (SNN), which when driven by ideothetic input is subject to drift. We show that head direction predictions made by the chosen model-free visual learning algorithms can correct for drift, even when trained on a small training set of estimated head angles self-generated by the SNN. We validate this model against experimental work by reproducing cue rotation experiments which demonstrate visual control of the head direction signal.
Appendicitis as a Leading Manifestation of Kawasaki Disease in Older Children

Kawasaki disease (KD) is a systematic inflammatory disease with multiple organ involvement. Timely diagnosis and prompt management are essential for successful treatment. KD, with an atypical presentation, remains a diagnostic challenge for physicians. We report a five-year-old boy who presented with appendicitis. An appendectomy was performed; however, his fever persisted. The boy was diagnosed with KD and intravenous immunoglobulin was administered. His symptoms resolved, and he had an uneventful recovery. Furthermore, we performed a literature review with 13 cases identified in the literature. Most cases were male, and the average age was older than typical for KD. In conclusion, KD may present with abdominal complaints and appendicitis may be a rare initial presentation of KD. Multidisciplinary cooperation and high awareness are warranted for timely diagnosis, especially in older children experiencing persistent fever after an appendectomy.
Iliacus Muscle Hematoma an Uncommon Complication in a Rehabilitation Unit: A Case Report Study

Iliacus muscle hematoma is a very rare condition in rehabilitation wards. A 35-year-old pregnant woman at seven months with cerebellar hematoma with signs of compression underwent a cesarean procedure together with neurosurgical decompression of the posterior cranial fossa procedure. After a period in an intensive unit without any complications, she was admitted to our neurorehabilitation ward and treated with antihypertensive therapy, heparin, and anti-seizure drugs. During a rehabilitation session, after a bed–wheelchair transfer, she was feeling very unwell suffering from severe right leg pain radiating to the mid-face leg. Despite unremarkable physical evidence (skin appearance, temperature, and peripheral arterial pulse in both legs), imaging data (ultrasound, CT, and MRI) confirmed the presence of a right iliac muscle hematoma (IMH). Enoxaparin was immediately stopped, and bed rest was prescribed in an antalgic position with tramadole acetaminophen for pain control. After a few days, the patient felt well and was discharged without any additional symptoms. Our study demonstrates that, when a sudden severe leg pain develops, IMH should be considered in the differential diagnosis. This finding suggests further research and tailored protocols for rehabilitation in patients at high risk for iliacus muscle hematoma.
Competitiveness of Early Vigour Winter Wheat (Triticum aestivum L.) Genotypes Is Established at Early Growth Stages

Weed competitiveness in wheat (Triticum aestivum L.) has previously been shown to be positively associated with shoot biomass. This study evaluated the impact of increased early shoot vigour on the weed competitiveness of Australian winter wheats. Breeding lines generated for early shoot vigour were top-crossed with two commercial wheat cultivars (Yitpi and Wyalkatchem) and the resulting high vigour lines (HV lines) were assessed for early growth and weed pressure in the field. These lines were directly compared with their parental lines, other commercial cultivars, and the tall heritage cultivar, Federation. Moreover, rye (Secale cereale L.) or triticale (× Triticosecale) was included in each trial as a positive control for vigour. The association between shoot growth and vigour and weed suppression was evaluated over 3 years in the cereal belt of south-eastern Australia during contrasting seasons. The HV lines consistently displayed greater leaf area, ground cover, and canopy light interception in both dry and wet seasons and suppressed weed growth significantly in contrast to commercial cultivars. Light interception at the first tiller stage, and ground cover at the end of tillering were identified as the most important variables for predicting weed suppression. This study demonstrated the enhancement of competitiveness in commercial wheat through the selection for early vigour, and identified traits that best predicted weed suppression.
Usability of Smart Home Thermostat to Evaluate the Impact of Weekdays and Seasons on Sleep Patterns and Indoor Stay: Observational Study

Background Sleep behavior and time spent at home are important determinants of human health. Research on sleep patterns has traditionally relied on self-reported data. Not only does this methodology suffer from bias but the population-level data collection is also time-consuming. Advances in smart home technology and the Internet of Things have the potential to overcome these challenges in behavioral monitoring. Objective The objective of this study is to demonstrate the use of smart home thermostat data to evaluate household sleep patterns and the time spent at home and how these behaviors are influenced by different weekdays and seasonal variations. Methods From the 2018 ecobee Donate your Data data set, 481 North American households were selected based on having at least 300 days of data available, equipped with ≥6 sensors, and having a maximum of 4 occupants. Daily sleep cycles were identified based on sensor activation and used to quantify sleep time, wake-up time, sleep duration, and time spent at home. Each household’s record was divided into different subsets based on seasonal, weekday, and seasonal weekday scales. Results Our results demonstrate that sleep parameters (sleep time, wake-up time, and sleep duration) were significantly influenced by the weekdays. The sleep time on Fridays and Saturdays is greater than that on Mondays, Wednesdays, and Thursdays (n=450; P<.001; odds ratio [OR] 1.8, 95% CI 1.5-3). There is significant sleep duration difference between Fridays and Saturdays and the rest of the week (n=450; P<.001; OR 1.8, 95% CI 1.4-2). Consequently, the wake-up time is significantly changing between weekends and weekdays (n=450; P<.001; OR 5.6, 95% CI 4.3-6.3). The results also indicate that households spent more time at home on Sundays than on the other weekdays (n=445; P<.001; OR 2.06, 95% CI 1.64-2.5). Although no significant association is found between sleep parameters and seasonal variation, the time spent at home in the winter is significantly greater than that in summer (n=455; P<.001; OR 1.6, 95% CI 1.3-2.3). These results are in accordance with existing literature. Conclusions This is the first study to use smart home thermostat data to monitor sleep parameters and time spent at home and their dependence on weekday, seasonal, and seasonal weekday variations at the population level. These results provide evidence of the potential of using Internet of Things data to help public health officials understand variations in sleep indicators caused by global events (eg, pandemics and climate change).
Phosphorus forms and distributions in soils under selected land use practices at the Federal University of Agriculture, Abeokuta, Ogun State, Nigeria

The forms and distributions of phosphorus were determined for four different land use practices in Federal University of Agriculture, Abeokuta, with the aim of evaluating the effects of land use and soil depth on soil physical and chemical properties, forms and distributions of phosphorus. The study was a 4×2 factorial experiment laid out in a Randomized Complete Block Design. Factor 1 was four different land use practices (Gmelina arborea, Tectona grandis, Leucaena leucocephala plantations and secondary forest), and Factor 2 was soil samples collected from two soil depths (0-30cm and 30-60cm). The soil pH, electrical conductivity, exchangeable bases (Na, K, Mg and Ca), particle size, organic carbon, total nitrogen, total phosphorus, inorganic phosphorus fractions (Al-P, Fe-P and Al-P) and available phosphorus analyses were carried out using standard procedures. Data collected from the laboratory analysis were subjected to two-way Analysis of Variance while the means among the treatments were separated using Duncan Multiple Range Test. The results showed that the soils had low total and available P contents. The soil under Leucaena leucocephala plantation had the highest total phosphorus (111.05mg kg-1), followed by Tectona grandis (97.63mgn kg-1), Gmelina arborea (96.41mg kg-1) and secondary forest (83.63mg kg-1). Total P decreased with depths (0-30cm and 30-60cm). Inorganic P-fractions were greatly influenced by soil properties such as soil pH, soil electrical conductivity, organic carbon, and soil particle size. The inorganic phosphorus fractions of the soils in all study area occurred generally in the following sequential order; Fe-P>Ca-P>Al-P. The highest inorganic phosphorus recorded in all in the study area was Fe-P, followed by Ca-P and Al-P. Al-P had the lowest content between the depths examined. Lower nutrient concentrations in soils under secondary forest within the depths were due to lower organic matter content, higher nutrient demand, nutrient immobilization by tree species and other flora present. P fractionation investigations are therefore recommended in soils under indigenous species plantation in order to provide adequate understanding of P status in the soils and fertilizer recommendation so as to improve productivity.
Constraining uncertainties of diazotroph biogeography from nifH gene abundance

Marine diazotrophs fix dinitrogen gas into bioavailable nitrogen that drives the ocean nitrogen cycle; yet, efforts to infer global diazotroph distributions have been limited by a sparsity of observations. In situ measurements of nifH gene abundance (essential for nitrogen fixation) are increasingly being used to inform the biogeography of diazotrophs. However, comparing such gene abundances spatially, temporally and between diazotroph species remains difficult. We synthesize existing data on gene‐to‐cell and cell‐to‐biomass conversions for four major diazotroph groups to convert nifH gene counts to abundance‐ and biomass‐based biogeographic “currencies. ” Results suggest up to two orders of magnitude uncertainty converting from nifH gene abundance to cell abundance, and up to four orders of magnitude uncertainty from nifH gene abundance to biomass. Uncertainty arises due to large taxonomic variation in cell size and presumed polyploidy, that is, variability in the number of genomes per cell. Such uncertainties hinder comparing biogeographies of different species. Additionally, numerical models need biogeographies for validation, typically in the currency of carbon biomass. Here, we show that conversion uncertainty from nifH gene abundance to biomass overwhelms biomass variability simulated in such models. These results demonstrate a basic currency problem in converting gene abundance observations to biogeographically meaningful quantities for synthesizing studies and modeling approaches. Such issues may also have relevance to other genes and organisms beyond diazotrophs. To avoid biases in interpreting gene counts as a measure of abundance, we suggest converting gene counts to a binary presence/non‐detect metric to map broad biogeographical distributions more robustly.
The Effect Of Silver Versus Titanium Dioxide Nanoparticles On Poly methylmethacrylate Denture Base Material

Materials and methods: Three groups of heat cured acrylic resin specimens were prepared; the first was Group C made of conventional heat cured acrylic resin, the second group was Group Ag where the acrylic resin specimens were incorporated with 5% Silver nanoparticles, and the third group Ti had its specimens incorporated with 5% Titanium oxide nanoparticles. The specimens were tested for microbial colonization using direct culture and serial dilution methods. The specimens were then further tested for surface roughness. Results: There were higher bacterial counts in specimens of group C (control) 51.12±4.7198 than those with Ag nanoparticles 32.44±2.7701 and TiO2 nanoparticles 31.92±2.2159. The difference was statistically significant between the control group (C) and the Ag nanoparticles group and between the control group and the TiO2 nanoparticles group. However, there was a statistically non-significant difference between the Ag nanoparticles group and TiO2 nanoparticles group. Statistical analysis by ANOVA for repeated measures showed statistically non-significant difference between the three groups regarding the surface roughness. Conclusions: Ag and TiO2 nanoparticles had a similar antimicrobial effect when added to PMMA, The addition of 5% of Ag and TiO2 nanoparticles has not affected the surface roughness of PMMA.
