Impacts of Growth Substrate and Container Size on Cutting Production from ‘Snow Angel’ Coral Bells Stock Plants

Stock plant productivity is an important concern for growers of ‘Snow Angel’ coral bells (Heuchera sanguinea) because this variety produces a limited number of basal cuttings. The objective of the study was to determine the best growth substrate and container size combination to maximize productivity of stock plants. A secondary objective was to determine if the stock plant treatments influenced the rooting of vegetative cuttings. The study used three different container sizes (2.8, 11.4, and 14.6 L) and four commercial soilless substrates that were primarily composed of the following: bark, peat, and perlite (substrate 1); bark, peat, and vermiculite (substrate 2); bark, peat, and coarse perlite (substrate 3); and peat (substrate 4). Two stock plant experiments were conducted using the same 12 treatment combinations, and a subset of those stock plants was randomly selected for the rooting studies that immediately followed each stock plant experiment. Stock plants responded to substrate treatments differently depending on the batch of substrate in which they were grown. The most successful stock plants, which produced more cuttings per plant and per square foot, as well as larger cuttings, were those grown in substrate 3 (Expt. 1) and substrate 2 (Expt. 2). Regardless of the substrate, the highest number of cuttings per square foot was obtained from stock plants grown in 2.8-L containers, indicating that the smaller containers allow for the most efficient use of space when growing ‘Snow Angel’ stock plants for 6 to 8 months. The rooting of vegetative cuttings was successful (98% to 100% of cuttings rooted after 4 weeks under mist) for all treatment combinations, although higher numbers of visible roots were produced during the second study and may be due to larger fresh weights of cuttings.
A current affair: entanglement of humpback whales in coastal shark‐control nets

Shark‐control nets pose an entanglement risk to East Australian humpback whales during their annual northward and southward migrations between the Southern Ocean and the Coral Sea. Rates of whale entanglement exhibit seasonal and interannual variation, suggesting that an understanding of the influence of variability in the broad‐scale physical environment along the migratory route would be useful in assessing risk of entanglement. This study provides a quantitative spatio‐temporal analysis of the probability of whale entanglement in shark‐control nets relative to the position and characteristics of the East Australian Current (EAC), the dominant oceanographic feature of the region. We use satellite‐derived sea‐surface temperature, and outputs from a data‐assimilating ocean model, to develop multivariate, data‐driven algorithms for detecting the edge of the EAC using Principal Components Analysis. We use outputs from these algorithms to model the likelihood of humpback entanglements in South‐east Queensland. We find that the likelihood of entanglement increases when the EAC edge is locally less structured and closer to shore in the vicinity of the corresponding net, or when the EAC is well resolved over the entire study domain. Our results suggest that migrating humpbacks use the gradient in physical characteristics that marks the EAC inner edge as a navigational aid. Thus, when the EAC inner edge encroaches on the coast, the whales’ migration range is compressed into nearshore waters, increasing the risk of entanglement. Our findings can help predict periods of elevated entanglement risk, which could underpin a more data‐driven approach to the management of shark‐control programs, and other activities that involve static fishing gear.
What SES may explain about work-related health limitations: A temporal-ordered model

ABSTRACT While health’s relationship to SES is well established by research, relevant studies in the literature display little uniformity in their conceptualization of SES. The present study sought a temporal-ordered model reflecting longitudinal data and explaining work-related health limitations (health conditions that limit the amount or type of work an individual can perform) in the period 2008–2015. The data came from the 1997 cohort of the National Longitudinal Study of Youth, a panel study originating in the United States. From it we developed a longitudinal record for each of 5,487 respondents, yielding 23,951 person-waves in the final sample. Specifically, we examined how SES impacts work-related health limitations among working young adults as they transition to midlife. Our analyses employed generalized estimating equations (GEE). Our results linked higher likelihood of work-related health limitations to self-employment, to being a laborer (versus a professional/manager), and to working in entertainment/accommodation/food services, educational/health/social services, professional and related services, and other industry (versus construction/agriculture/manufacturing). Overall, our longitudinal study indicated that SES measured relatively early in the lifecourse helps explain work-related health limitations among working young adults, net of lifestyle, and health-care-use variables.
Flexible and Efficient Long-Range Planning Through Curious Exploration

Identifying algorithms that flexibly and efficiently discover temporally-extended multi-phase plans is an essential step for the advancement of robotics and model-based reinforcement learning. The core problem of long-range planning is finding an efficient way to search through the tree of possible action sequences. Existing non-learned planning solutions from the Task and Motion Planning (TAMP) literature rely on the existence of logical descriptions for the effects and preconditions for actions. This constraint allows TAMP methods to efficiently reduce the tree search problem but limits their ability to generalize to unseen and complex physical environments. In contrast, deep reinforcement learning (DRL) methods use flexible neural-network-based function approximators to discover policies that generalize naturally to unseen circumstances. However, DRL methods struggle to handle the very sparse reward landscapes inherent to long-range multi-step planning situations. Here, we propose the Curious Sample Planner (CSP), which fuses elements of TAMP and DRL by combining a curiosity-guided sampling strategy with imitation learning to accelerate planning. We show that CSP can efficiently discover interesting and complex temporally-extended plans for solving a wide range of physically realistic 3D tasks. In contrast, standard planning and learning methods often fail to solve these tasks at all or do so only with a huge and highly variable number of training samples. We explore the use of a variety of curiosity metrics with CSP and analyze the types of solutions that CSP discovers. Finally, we show that CSP supports task transfer so that the exploration policies learned during experience with one task can help improve efficiency on related tasks.
Combining laboratory-based learning with problem-based learning in undergraduate PLC course at Technical Colleges

The necessity of accomplished engineers and technicians, who are competent in handling the problems of the emerging industry, brings the conventional teaching approaches into question. Engineering technology students should be skilled to confront the technical challenges they will come across in their professional careers by using innovative teaching methods based on projects and real industrial applications. In this study, Teaching-Learning Environments for PLC Program were enhanced, as it is taught to the Electrical and Electronic department students in the Technical Colleges. The emphasis is on the content of a course unit, particularly the choice of the learning methods and its effect on the students. This complete PLC program combines laboratory-based learning with a problem-based learning (PBL) approach. It is also aimed to develop the students' practical skills and meet the requirements of the labor market. Data collected from the labor market and discussed with the academic experts guided us to set our approach, develop the program and improve the students’ practical skills. Coming into practical, we have received a lot of positive feedback from students after carrying out a survey and before determining its educational effectiveness.
The Impact of Soil Erosion on Biodiversity Conservation in Isiala Ngwa North LGA, Southeastern Nigeria

The impact of soil erosion on the conservation of biodiversity in Isiala Ngwa North LGA, Southeastern Nigeria was examined. Data were obtained through focus group discussions and plant species enumeration. Diversity indices of plant species were derived from quadrat analysis using Shannon Wiener’s diversity index. Eighteen soil samples were collected from agricultural erosion sites in the study area and analysed in the laboratory. The results obtained were analysed using principal component analysis (PCA). The rotated component matrix of the soil properties, as well as plant and animal diversity indices from the PCA isolated three components that together explained 93.821% of the observed variation. The results show that bush clearing in the form of slash and burn, uncoordinated bush burning and harvesting of plant species are the activities that cause soil erosion in the study area. Agro-forestry, bush fallowing, reforestation and legislation on indiscriminate harvesting of plant species were recommended.

Categories of Information Need Expressed by Parents of Individuals with Rare Genetic Disorders in a Facebook Community Group: A Case Study with Implications for Information Professionals

Abstract Costello syndrome is a rare genetic disorder that affects virtually all aspects of an individual’s life. Few specialists have been trained to understand the condition and provide guidance to caregivers and virtually no traditional information sources (e.g. books, websites) exist to provide information to caregivers. In this case, the community becomes a major source of information for caregivers of individuals with this condition. This study examines the types of information that need to be expressed in one of these communities: an online Facebook group. The categories of information need to be identified in the study to demonstrate areas of concern to caregivers and offer areas for further research or publication for researchers of rare disorders and health conditions. The role of information professionals in satisfying these information needs of caregivers of individuals with Costello syndrome and other rare disorders.

The design and performance of a compact laser system for autonomous cooling of rubidium atoms in a small Cube-Sat satellite is described. The laser system is suitable for use in cold atom interferometers that are deployed in space for accurate observation of earth’s gravity and magnetic fields and detection of tectonic changes. The laser system features a frequency doubled DFB laser and erbium doped amplifier, which is mainly fabricated from telecommunications qualified components with proven high reliability. The laser has an output power of greater than 75mW with a sub-MHz linewidth and a tuning range of greater than 300GHz. The laser and drive electronics fit into a 200mm x 100mm x 30mm package and have a mass of less than 1kg. On-board the CubeSat the laser has been used to demonstrate atom cooling and to autonomously acquire and lock to the magneto-optical trap using feedback from the cold Rb-atom fluorescence to control the dfb laser frequency. The complete cube-sat has passed vibration tests for rocket launched conditions.
Teacher Experiences With Technology Initiatives And Understandings

At the secondary public school level, there have been many technology initiatives introduced to teachers for classroom and administrative use. Despite the upgrades in technology, teachers’ have not had many opportunities to express how the initiatives are experienced and understood. The purpose of this study explored the experiences of teachers using technology within their profession and allowed them to express the impact their experiences had on their profession. Specifically, the study investigated teachers' experiences with technology initiatives at the high school level. An extensive literature review related to technology in the secondary education level was conducted along with an exploration of Bandura’s theory on self-efficacy applied as a theoretical framework. The research design, data collection, and analysis of the study followed. Nine Secondary Public High School science teachers from the same school district participated in an open interview process where data was collected, coded, and analyzed using qualitative interpretational phenomenology analysis (IPA) methodology. This process led to the researchers’ understanding of the participants’, teachers’, technology initiatives and understandings in the secondary high school setting.
Lowering Hyperhomocysteinemia to Diminish the Risk of Cardiovascular, Cerebrovascular and Peripheral Artery Disease: A Review of Evidence on Nutritional Preventive Interventions

Hyperhomocysteinemia is an independent risk factor for atherothrombotic cardiovascular disease, lacunar infarction, cerebrovascular disease and peripheral artery disease. However, early hallmark clinical studies on the benefits of nutrients supplementation for decreasing homocysteine (Hcy) levels and vascular events showed contradictory results. In the present review, recent meta-analyses and selected clinical studies on the use of micronutrients as diet complements to prevent hyperhomocysteinemia and related vascular disease are summarised. Its objective is to identify subgroups of patients that could benefit the most from closer nutritional surveillance and eventual dietary complementation. Results on preventive nutritional interventions were more consistent for stroke than for myocardial infarction. The reviewed publications showed that oral dietary complementation with the combination of folic acid, B6-, and B12-vitamins substantially lowers circulating Hcy levels compared to vitamins given alone. Patients younger than 69 years of age, with intracranial small vessel disease, from regions without folic acid food fortification or with poor dietary intake, with higher baseline cholesterol and Hcy levels and those not receiving antiplatelet or lipid-lowering drugs may obtain the larger benefits from nutritional interventions Better results may be observed with a duration of interventions of > 36 months. Given the frequent underdiagnosis of B12 vitamin deficiency, serum B12 and total Hcy should be checked routinely in cardiovascular and cerebrovascular disease patients and elevated total Hcy should be treated.
Methods for design and fabrication of bio-inspired nanostructures exhibiting structural coloration

In recent years, structural color has burgeoned into a vibrant and dynamic field of study. Many structurally colored organisms rely on comparatively few materials to create a large diversity of optical responses and a broad array of compelling and functional features. Scientists and engineers often explore such systems as examples of sustainable, robust solutions to complex problems. By looking to existing hierarchical material systems in biological systems, we aim to determine guidelines for fabrication of material structures with pre-determined functionality and properties. Here, we compare approaches for producing surfaces that reflect color and discuss tunable design parameters. Methods discussed include bottom up self assembly, abstracted lithographic replication of structures, and top down systematically designed surfaces. We consider existing techniques and levers available to control output, and present the components of an inverse design approach. We compare different methods on the basis of scalability, tunability, and achievable responses, and provide practical guidelines for producing bio-inspired surface structures. Our proposed designs are constrained for realizable fabrication using additive direct laser writing techniques such as two-photon polymerization that are suitable for producing arbitrary structures with sub-wavelength resolution. These evaluated and characterized structures could eventually be adapted to roll to roll or imprint based systems for scale-up and manufacturing on a commercial scale. Here we contribute to a broader vision of systematic materials design by exploring tools for generating color.
Actual Use of Multiple Health Monitors Among Older Adults With Diabetes: Pilot Study

Background Previous studies have reported older adults’ perceptions of using health monitors; however, no studies have examined the actual use of multiple health monitors for lifestyle changes over time among older adults with type 2 diabetes (T2D). Objective The primary aim of this study was to examine the actual use of multiple health monitors for lifestyle changes over 3 months among older adults with T2D. The secondary aim was to explore changes in caloric intake and physical activity (PA) over 3 months. Methods This was a single-group study lasting 3 months. The study sample included participants who were aged ≥65 years with a diagnosis of T2D. Participants were recruited through fliers posted at the Joslin Diabetes Center in Boston. Participants attended five 60-min, biweekly group sessions, which focused on self-monitoring, goal setting, self-regulation to achieve healthy eating and PA habits, and the development of problem-solving skills. Participants were provided with the Lose It! app to record daily food intake and devices such as a Fitbit Alta for monitoring PA, a Bluetooth-enabled blood glucose meter, and a Bluetooth-enabled digital scale. Descriptive statistics were used for analysis. Results Of the enrolled participants (N=9), the sample was white (8/9, 89%) and female (4/9, 44%), with a mean age of 76.4 years (SD 6.0; range 69-89 years), 15.7 years (SD 2.0) of education, 33.3 kg/m2 (SD 3.1) BMI, and 7.4% (SD 0.8) hemoglobin A1c. Over the 84 days of self-monitoring, the mean percentage of days using the Lose It! , Fitbit Alta, blood glucose meter, and scale were 82.7 (SD 17.6), 85.2 (SD 19.7), 65.3 (SD 30.1), and 53.0 (SD 34.5), respectively. From baseline to completion of the study, the mean daily calorie intake was 1459 (SD 661) at week 1, 1245 (SD 554) at week 11, and 1333 (SD 546) at week 12, whereas the mean daily step counts were 5618 (SD 3654) at week 1, 5792 (SD 3814) at week 11, and 4552 (SD 3616) at week 12. The mean percentage of weight loss from baseline was 4.92% (SD 0.25). The dose of oral hypoglycemic agents or insulin was reduced in 55.6% (5/9) of the participants. Conclusions The results from the pilot study are encouraging and suggest the need for a larger study to confirm the outcomes. In addition, a study design that includes a control group with educational sessions but without the integration of technology would offer additional insight to understand the value of mobile health in behavior changes and the health outcomes observed during this pilot study.
Electrohydrodynamic Processes and Their Affecting Parameters

Electrohydrodynamic processes such as electrospinning and electrospraying are simple, flexible, and cost-effective. Both processes use electrically charged jet of polymer solution for the fabrication of micro- or nanofibers and micro- or nanoparticle. Both of these electrodynamic techniques have been receiving increasing attention not only in the scientific community but also in industry. These fibers and particles offer several morphological and functional features that are suitable for tissue engineering in biomedical applications. The main apparatus used for both of these processes is almost the same. Both need electric voltage to induce charge on the droplet, which at optimized electric field leads to micro- or nanofibers and micro- or nanoparticles. Rayleigh in 1882, for the first time, theoretically estimated the maximum amount of charge that a liquid droplet could carry to change in a jet. This theory is now known as the “Rayleigh limit. ” He predicted that a droplet on reaching Rayleigh limit would move as fine jets of liquid. More than 100 years later, Rayleigh limit theory was confirmed experimentally. Beside electric field there are other operating and solution parameters that need to be optimized before we obtain a desire product.
Parenting Style, Feeding Patterns, and Adolescent Eating Behavior in South Kalimantan between Male and Female Adolescents

Parenting style and parenting eating patterns are a way of controlling teenagers eating behavior. This study aims 1) to analyze gender differences in adolescent characteristics, family characteristics, feeding patterns, and eating behavior; 2) to analyze the effect of adolescent characteristics, family characteristics, and feeding patterns on adolescent eating behavior. This study used a cross-sectional study design with survey methods. The sample of this study was 160 adolescents (61 boys and 99 girls who were in grade 10 of high school). The results of the T-test showed that there were no significant gender differences in adolescent characteristics and family characteristics. There were significant differences in authoritarian parenting style, feeding patterns and eating behavior between boys and girls. The results of the regression analysis showed that eating behavior was influenced by age and feeding patterns.
