Rolling motion of a ball on a turntable

A solid ball placed on a rotating turntable is known to roll slowly around a circular path, at a speed 3.5 times slower than the turnable itself. If the ball is located in a straight track across a diameter of the turntable, then it accelerates rapidly to the edge. Both effects were filmed in slow motion using a video camera and a cake decoration turntable, and are presented as supplementary videos. The results agree well with calculations based on rolling motion of the ball.
Renal Tract Abnormalities on Ultrasonography in Spinal Cord Injury Patients

Study Design: Retrospective pilot study. Purpose: To assess the incidence of renal tract abnormalities using ultrasonography (US) in a military cohort with traumatic spinal cord injury (TSCI) at a tertiary level spinal cord injury center. Overview of Literature: Neurogenic bladder in TSCI patients results in significant urological morbidity. There is lack of data for these patients during the first 18 months of long-term rehabilitation in an institutional setting. Methods: We retrospectively reviewed patient records to collect data on demographic characteristics, injury level, injury severity, time since injury, bladder management methods (such as an indwelling catheter [IC], clean intermittent catheterization [CIC], or selfvoiding [S]); we correlated these data with the findings of the renal tract US. Results: The study included 73 out of 81 male participants. The mean patient age was 29.99 years; the study group included 34.2% tetraplegics and 65.8% people with paraplegia. The time since injury was 6–12 months for 42.5% of the subjects and 12–18 months for 57.5% of the subjects. A normal US scan was recorded in 65.7% patients, and bladder trabeculation was the commonest finding in 15.1% of the subjects, followed by hydronephrosis (HDN) in 12.3%, and renal calculus and atrophy in 1.3% participants each. We found 22.22% of the IC group participants had higher US abnormalities than those in the reflex voiding group (statistically nonsignificant difference, p=0.7). Trabeculations (21.4%) and HDN (19%) were more common in those who had sustained the injury 12–18 months previously as compared to that in those who had injured themselves 6–12 months previously (p=0.04). The proportion of patients who had a normal US scan was higher in the group who sustained the injury 6–12 months previously versus those who had sustained the injury 12–18 months previously; the difference was statistically significant (p=0.02). There was no significant (p=0.72) correlation in the bladder management method, injury level, and renal tract abnormalities between the groups. Conclusions: This retrospective study shows that 65% of TSCI participants had no renal tract abnormality on US scan and bladder trabeculation ruled out as the most common finding. Long-term supervised rehabilitation may help achieve good renal quality of life; however, further prospective trials are required on this subject.

Young people’s sharing of sexualized digital imagery: Processes of acceleration in human- technology interactions

The ubiquity of smartphones and social media has introduced new ways of being connected and engaged in digitally mediated spaces, including the possibilities of exchanging private sexualized digital imagery – a practice known as ‘sexting’. In this paper, we study the ways in which young people’s engagement in both consensual and non-consensual sexting practices is facilitated – and sometimes even accelerated – by technology. Our study is based on focus group interviews with young people aged 16-21, 6 months of digital ethnography on social and digital media, and posts concerning sexting written by young people on Danish counselling websites. We draw on perspectives from postphenomenology and new materialism in order to focus on human-technology interactions and how digital technologies shape social processes and interactions when young people exchange sexualized digital images and videos. We attend to the ways the affordances of social media (e.g., spreadability, ephemerality and persistence) facilitate and mediate young people’s sharing of sexualized imagery and how the affects emerging through these processes produce intensities, fantasies and intimacies, which both motivate and accelerate these practices. Our analyses seek to refine current understandings of young people’s production and sharing of sexualized digital imagery. Moreover, we argue that there is a need for further development of psychological concepts and analyses that can adequately grasp the nuances of the complex digital and visual intimate, social, sexual processes of young people’s lives and advance the research field of sexting among young people.
Regularised Weights in Statistical Models

For flexible and overparameterised models like neural networks, overfitting can be a notorious problem that makes it hard to give accurate predictions in real-life usage. Overfitting is in particular likely in the presence of errors in the training data, such as misclassifications or outliers. Therefore it is essential to either carefully inspect the data or, more realistically, adapt the training algorithm to reduce variance and overfitting. To reduce the risk of overfitting, a common approach is to manipulate the loss function. Either by adding a penalty on the model’s flexibility, which reduces variance with a cost of an increased bias, or weight the loss contribution from different data points in order to reduce the influence of harmful data. This thesis introduces a self-maintained method to reweigh different components (observations and/or parameter regularisation) in the loss function during training. With some care with the choice of model, these weights can be solved for, leading in the end to only a modification in the loss function. Due to this, the resulting method can easily be combined with other regularisation techniques. Using the weighting technique on observations in a setting with mislabeled data produces more robust training than an unweighted model and detects mislabeled examples in data. When used on the regularisation penalty, the weights reduces bias introduces by the regularisation term while keeping some crucial attributes from the original penalty.

Sediment dynamics are determined by the synergy between the hydrodynamic condition and sediment properties. This study analyzed, between the years 2015-2017, the spatial and temporal changes in sediment texture of a shallow embayment in the Patos Lagoon estuary (Southern Brazil), and the influence of environmental parameters in these variations. Two areas were selected: an area more exposed to the estuary main channel dynamics and NE winds, and the other protected from them by islands. Each area was divided in shallow (mean depth <2m) and deeper zones (mean depth ≥2 m). The organic matter content presented a spatial and temporal variation, with maximum values higher than previously reported. Due to elevated rainfall rates during the winter and spring of 2015, higher values of fine sediments and organic matter were recorded, mainly at deeper zones. The protected area presented smaller grain sizes and their variability was correlated with wind speed and direction. While in the exposed area the water depth has a higher influence in the granulometric variations, decreasing grain sizes with depth increases. The higher seasonality in the granulometric variation was observed in the deeper zones, which presented the smaller grain sizes and lower values of asymmetry, decreasing these values in winter and spring. In conclusion, few centimeters in water depth may cause large changes in bottom types (or in the relative amount of sand, silt and clay) of shallow estuarine areas. From the environmental variables measured, wind, rainfall and bathymetry were the most influential in the temporal variation of the sediments, while hydrodynamic exposure on the spatial differences.
Folk Medicine in the Philippines: A Phenomenological Study of Health-Seeking Individuals

Background: Folk medicine refers to traditional healing practices anchored in cultural beliefs of body physiology and health preservation. Reflective of indigenous heritage, it fosters a better understanding of health and disease, healthcare systems, and biocultural adaptation. In the Philippines, Quiapo is a well-known site for folk medicine services, cultural diversity, religious practices, and economic activities. Methods: This study utilized a phenomenological approach to comprehend the lived experiences of health-seeking individuals and the meaning behind their acquisition of folk medicine products. Using convenience sampling, seven participants acquiring folk medicine products in Quiapo on the day of data collection were approached and interviewed on separate instances. The collected data subsequently underwent thematic analysis. Results: Analysis revealed three emergent themes: health-seeking behavior, sources of knowledge, and folk medicine utilization. Health-seeking behavior was linked with the participants’ purpose of going to Quiapo, reasons for utilizing folk medicine, experiences in using folk medicine, and beliefs associated with the product bought. Sources of knowledge tackled the participants’ sources of information about Quiapo and its products. Folk medicine utilization relates to the type of product bought, its perceived medicinal use, and its history of usage. Conclusion: Folk medicine is perceived to be effective in alleviating health concerns. The acquisition of such products is attributed to satisfaction from prior experience, distrust in the current healthcare system, family tradition, and intention to supplement existing medical treatment. This study provides health professionals a better understanding of patients who patronize folk medicine, subsequently aiding them in providing a holistic approach to treatment.
Neuropathic foot ulcer: microbiological assessment in chronic osteomyelitis

Objective: To determine the microbiological profile and antimicrobial susceptibility patterns of organisms isolated from chronic osteomyelitis secondary to neuropathic foot ulcers; secondarily, to describe the clinical outcomes of 52 patients admitted to a neuropathic foot referral center. Methods: Retrospectively chart review of 52 patients with clinically infected neuropathic foot ulcers admitted to our service for treatment between 2005 and 2013. Tissue samples were collected for culture at the operating room after extensive debridement in order to determine the infectious agents and their resistance profile using the disk-diffusion technique, following CLSI criteria. Results: A total of 52 patients were analyzed (40 males and 12 females). The mean age was 58 (37-72) years. Each patient presented with an average of 2.13 microorganisms, distributed as follows: 51% Gram-positive cocci, 43% Gram-negative bacilli. Among Staphylococcus aureus isolates, the prevalence of methicillin resistance was almost 50%, and the prevalence of coagulase-negative staphylococci (CoNS) was more than 75%. Conclusion: S. aureus, E. faecalis, and CoNS were the most frequently isolated pathogens. Methicillin resistance was highly prevalent. A combination of extensive surgical debridement and prolonged antimicrobial therapy led to remission of infection in 77% of patients. Level of Evidence IV; Therapeutic Studies; Case Series.
EFFECT OF ADDING BIOCHAR AND DIFFERENT RATES OF CHEMICAL FERTILIZATION ON GROWTH AND YIELD OF GLOBE ARTICHOKE PLANTS GROWN IN SANDY SOIL

A field experiment was carried out during two successive winter seasons of 2017/2018 and 2018/2019 at the Experimental Farm of ElKassasin Horticultural Research Station, Ismailia Governorate, Egypt, to study the effect of different rates of mineral NPK ( 100, 75, 50 and 25 % of the recommended rates) and biochar (0, 1, 2 and 4 m 3 /fad.) on growth, yield and head quality of globe artichoke plants grown in sandy soil. Results showed that , the interaction between fertilizing globe artichoke plants with NPK at 100 % of recommended rates (RR) and treating with biochar at 4 m 3 /fed, significantly increased plant height , leaf fresh weight and offshoots number / plant, highest number ofearly heads/ plant , number of total heads/ plant , total yield / plant , total yield /fed. and total sugars (%) in receptacle in both seasons. While, the interaction between fertilizing globe artichoke plants with NP K at 75 % of RR and treating with biochar at 4 m 3 /fed. significantly enhanced leaf dry weight and all flower head quality such as head fresh weight, head diameter, receptacle fresh weight, receptacle diameter and receptacle thickness, with no significant differences between the interaction treatment between fertilizing with NP K at 100 % RR and treating with biochar at 4 m 3 /fed. in both seasons. However, reducing sugars and inulin (%) significantly enhanced with the interaction treatments between NPK at 100 or 75% of RR and treating with biochar at 4 or 2m 3 /fed. in both seasons . On the other hand, the lowest values of all plant growth parameter, yield and its components, head quality and chemical constituents of receptacles were obtained from the plants which received 25 % of the recommended rate of NPK in without biochar both seasons. Conclusively, it could be concluded that, fertilizing globe artichoke plant with NPK at 100% from recommended rate which equal 120 kg N, 62.0 Kg P2O5 and 120 kg K2O and treated with 4 m 3 /fed. was the best treatment for recorded the highest values of yield characters, and head

Montessori Education at a Distance, Part 2: A Mixed-Methods Examination of Montessori Educators’ Response to a Global Pandemic

: This study offers a contextualized understanding of the distance-learning experiences of Montessori educators and students in the spring of 2020 in the wake of the COVID-19 global pandemic. In this article, we build on results reported in a separate article published in this issue of the Journal of Montessori Research. First, we analyzed qualitative data from social media and national virtual gatherings designed to support teachers as they faced the challenges created by the abrupt shift to distance learning. Second, we employed a convergent mixed-methods design to integrate these qualitative findings with the survey results reported in the previous article to provide a richer and more complete perspective on the situation. In our results, we found substantial evidence to support the resilience and durability of the Montessori Method, even in the face of adverse conditions created by a global pandemic. Despite the challenges of adaptation, Montessori educators demonstrated a commitment to the key tenets of Montessori philosophy, such as following the child and employing a holistic perspective on learning and development. While serving the whole child’s growth and development remained front and center, Montessori teachers’ approach to academics looked very different under distance learning. Still, the ongoing attention to children’s social-emotional needs will benefit both teachers and children when they return to the classroom, undoubtedly with lasting effects from pandemic-related isolation and hardship.
Genetic structure of three Mexican bamboo species

https://creativecommons.org/licenses/by-nc/4.0/ Abstract Background: Sporadic flowering contributes significantly to genetic diversity and connectivity among populations. Woody bamboos present sporadic or gregarious flowering patterns with long flowering cycles. In this study, we analyze the genetic diversity of three Guadua species distributed along the Gulf of Mexico slope that have different patterns of flowering. Questions: (1) Are the three Guadua species genetically differentiated? (2) Does the vulnerable species G. inermis have low levels of genetic diversity? (3) What is the relative contribution of geographic and environmental factors to the genetic structure of G. inermis? Species studied: Guadua amplexifolia, G. inermis and G. tuxtlensis. Study site and dates: During 2014 and 2015, we collected samples of G. inermis in Puebla and southeastern Mexico, G. amplexifolia in Veracruz and Oaxaca, and G. tuxtlensis in southern Veracruz. Methods: We successfully amplified five of nine SSR markers, and genotyped a total of 155 samples. Results: The three Guadua species were genetically differentiated. For G. inermis, we found high levels of population genetic diversity, which are relatively higher than those of other monocot species. Genetic differentiation was high and three groups were detected: north, central and south. We found a significant association between genetic distances and the maximum temperature of the warmest month, but not with geographic distance. Conclusions: Our study is the first to analyze levels of genetic diversity in Mexican bamboos and confirms their taxonomic identity. G. inermis has a strong genetic structure, even when populations are geographically close.
Greening Monetary Policy: Climate Change Expectations and the Natural Rate

Using a representative consumer survey in the U.S., we elicit beliefs about the economic impact of climate change. Respondents perceive a high probability of costly, rare disasters due to climate change, but not much of an impact on GDP growth. Salience of rare disasters through media coverage increases the probability by up to 10 percentage points. Expectations about climate-change related disasters matter for monetary policy because they impact the natural rate of interest. We quantify this effect in a standard New Keynesian model and find that climate-change related disaster expectations cause a decline of the natural rate by about 70 basis points. If monetary policy fails to accommodate this effect, inflation and output decline by about 0.3 percent.
Simulation of fibre reinforced concrete structural failure based on bending test results

Composite materials like steel fibre reinforced concrete (SFRC) gain attention among engineers and designers. It is possible by adding fibres to increase ductility of such brittle materials as concrete. However, such materials are difficult to design, because the mechanical properties of SFRC are hard to predict. Nonlinear computer modelling based on the Finite Element Analysis (FEA) can be utilised to predict failure of a composite structure, if the material properties are defined correctly. Material model describing properties in tension and compression of the composite need to be defined. In practice uniaxial tension tests in case of SFRC are difficult to perform, therefore the properties of the material are represented by standard laboratory bending tests. These results cannot be used directly in nonlinear FEA simulation software. The aim of the study is to find the link between the results of standard bending tests and the material model in tension that could be used in simulation software. In the study ATENA GiD software is used for simulation purposes. The simulation is performed in conjunction with experimental results of 24 SFRC beams, tested according to the standard EN 14651. The material model of SFRC is obtained by an improved inverse analysis based on the bending test results. Parametric analysis of the SFRC material model is performed. As a result, a numerical method for converting the bending test results to the material model in tension is suggested. The evaluation of the proposed model shows ± 2.5% error at 3.5 mm of crack mouth opening distance in average, if the predicted and the actual fracture energy is compared.
Mortality predictors in acute kidney injury patients who underwent continuous venovenous hemodiafiltration: A retrospective, single-center study

Continuous renal replacement therapy (CRRT) is an increasingly preferred treatment that is easier to use in patients with hemodynamic impairment and can be applied in critical care settings. There are various subtypes of CRRT, one of which is continuous venovenous hemodiafiltration (CVVHDF). In this study, we examined the general characteristics of intensive care patients who underwent CVVHDF. Methods. The clinical and biochemical data of 123 patients who underwent CVVHDF in the intensive care units of our center between February 2012 and November 2014 were analyzed retrospectively. Patients who died during the course of therapy were compared with those who survived. Results. The study included 123 patients, 73 males (59.3%) and 50 females (40.7%). The mean age was 64.4 years. Eighty-eight patients (71.5%) died during CVVHDF while 35 patients survived (28.5%). Hemodynamic parameters such as systolic and diastolic arterial blood pressure, mean arterial pressure, and pulse pressure were significantly lower in patients who died compared to survivors (p<0.001). Mean lactic acid level was significantly higher in the deceased group than in the surviving group (8.54 mmol/L vs. 3.68 mmol/L, p<0.001, chi-square test). Conclusions. Low bicarbonate level, low systolic arterial blood pressure, and older age were significant independent predictors of mortality in this study. Mortality rates were significantly higher among patients with lactic acidosis and those over 66 years of age. Lactic acid levels can be used to predict mortality in patients undergoing CVVHDF.
