Published: July 2019

Abstract
One of the main problems of the collaborative mobile robot application is to share the exact information of the robot itself and the surrounding area. Each robot needs to maintain its stability and positioning in order to achieve the target. As one of the samples of achieving the positioning task, a parallel parking problem was used in this paper. This paper used a car-like robot to do a parallel parking task. Front wheels were steered by using a connected joint and a servo motor. Meanwhile, each of the rear wheels was connected to a motor DC. Four ultrasonic sensors were used to find the distance between the robot and its surrounding (fixed in front, back, middle right, and middle of right - back side). The sensors connected to an Arduino Uno as the main microcontroller. The robot used a positioning algorithm based on the distance to nearest objects. The robot is designed only for parking on the right side of the car with an assumption there is no obstacle in the left side of the car. The experimental results confirmed that our system can solve the parallel parking problem. However, during the test, the output of the sensor was were affected by the noise from the environment. Another problem was the robot hardly to move straight because the rubber tires were not installed neatly. In the future works, the data output needs to filter and corrected and the servo degree needs to be initially corrected based on the chassis and tires angle.

Published: July 2019

Abstract
Improvement in the germination process will improve the productivity of mung beans (Vigna radiata), peanuts (Arachis hypogaea), and tomatoes (Solanum lycopersicum), the three Indonesian important crops. Seed immersion in the water is one of the germination pre-treatments. The aim of the study was to evaluate the effects of seed immersion in pre-determined water on mung beans, peanuts, and tomatoes germination. The study used a factorial completely randomized design with three factors consisted of water pH (5, 7 and 9), water temperature (27 ºC and 50 ºC), and immersion time (15 and 30 minutes) on 3 replications. Seed germination process was carried out in a rolled paper method. The study showed that different water pH, water temperature, and immersion time gave a significant effect on the germinability, germination speed, seed vigor index, and the percentage of normal growth seeds. Moreover, the seed immersed in the water (pH 7, 50ºC) for 15 minutes showed the best effect on germination quality.

Abstract
This study investigated the structural and optical properties of Iron(III)-doped titanium dioxide (Fe-TiO2) powders which were synthesized by sol-gel method with a post-annealing temperature at 500°C. Iron(III)-doped titanium dioxide was prepared from Titanium (IV) Isopropoxide and Iron (III) Chloride (FeCl3). Iron (III) Chloride was added in different concentration (5, 7.5 and 10 % w/w). The synthesis powders were characterized by FTIR, Diffuse Reflectance Spectroscopy (DRS), Field Effect Scanning Electron Microscopy (FESEM), X-ray Diffraction (XRD) and BET. FESEM analysis showed the morphology of 10 % (w/w) Fe doped TiO2 were homogeneous with the presence of less aggregate of iron. Meanwhile, The surface area of the sample TiO2-Fe 7.5% calculated from the BET adsorption plot is 107.096 m2/g. This surface area is higher than the sample TiO2-Fe 10% is 95,241 m2. It is confirmed that iron insert to the pore of TiO2. DRS Analysis revealed the light absorption in the visible region was increased with increasing the iron concentration up to 10% (w/w).
Fractional factorial and D-optimal design for discrete choice experiments (DCE)
Authors: Tazliqoh A Z , Wigena A H , Syafitri U D 
Published: July 2019

Abstract
Discrete choice experiments (DCE) are a method to measure people’s preferences in various fields of application that used to estimate the importance of attributes of the product or service based on the respondent’s choice. The design of DCE consists of several choices called profiles in each choice set. The best DCE’s design depends on how to divide the profiles into each choice set so it needs a strategy to construct the appropriate DCE’s design. So, the purpose of our study is looking for the most appropriate strategy from two strategies used namely fractional factorial design as the first strategy and D-optimal design with a point-exchange algorithm as the second strategy. The quality of the two strategies is evaluated with the D-optimality criterion value. Both of them are simulated in the case that involves four attributes with two levels, respectively, so all possible profiles are 24 = 16 profiles. The first strategy gained DCE’s design that consisted of two choice sets and eight profiles, respectively. The second strategy gained two different DCE’s designs. The first design consisted of four choice sets and four profiles, respectively. The second design consisted of eight choice sets and two profiles, respectively. Both the first and second strategies have the same D-optimality criterion values but a difference in structure. In terms of statistics, both strategies have the same quality. However, in terms of application, the second strategy is more appropriate in the structure than the first strategy. Hence, the D-optimal design is an alternative to construct DCE’s design based on applications.
Mesostructural origin of the field-induced pseudo-plasticity effect in a soft magnetic elastomer
Authors: Stolbov O V , Raikher Yu L 
Published: July 2019

Abstract
A model is presented to studying the pseudo-plasticity effect in a soft magnetic elastomer: a weakly-linked polymer matrix filled with micron-size particles of a ferromagnet with virtually zero coercivity (e.g., iron carbonyl). If the filling fraction of the composite is sufficiently high, such a material displays a remarkable ability to radically change its rheological behavior: being subjected to external magnetic field, the sample loses its elasticity and responds to external mechanical load as if being made of a ductile substance with no tendency to restore its initial shape. In our simulations we show that, considering the system at the mesoscopic scale (as an assembly of particles embedded in an elastic continuum) and taking into account just the magnetostatic and elastic interactions, one is able to qualitatively correct reproduce the field-induced pseudo-plasticity effect.
Influence of length of partitions on the generation of transit flow in MHD-channel
Authors: Kolesnichenko I , Dolgikh V , Pavlinov A , Khalilov R 
Published: July 2019

Abstract
The process of the transit flow generation in the magnetohydrodynamic channel of the pump is investigated. Its design provides for the variation of the flow-rate of the liquid metal without changing the current in the channel. The pressure in the pump channel creates by an electromagnetic force through the interaction of a longitudinal electric current with its own magnetic field. C-shaped ferromagnetic cores are put on the channel. The current generates its own magnetic field which magnetizes the cores. The total magnetic induction vector of the current’s magnetic field and the field of the cores is orthogonal to the channel plane. The arising electromagnetic force generates a transit flow through the channel which is caused by the presence of flow partitions in it. The pump is tested on the gallium circuit. The pressure drop at the locked mode and variable flow rate mode for different values of channel overlapping by C-cores and their different numbers has been measured in the experiment. The pressure drop — flow-rate characteristics of the channel are determined at different values of overlap the channel.

Authors: Polunin V M , Ryapolov P A , Zhakin A I , Shel’deshova E V 
Published: July 2019

Abstract
The article gives an assessment of viscosity and its increment (‘magnetoviscous’ effect) in a thin near-wall layer of the column of magnetic fluid that oscillates in the tube when applying a strong transverse magnetic field. Viscosity is calculated according to a formula derived from two different theoretical approaches. For calculation, previously published experimental results, which were discussed earlier on the assumption that there is no field dependence of viscosity, are used in the article. A comparative analysis of the “near-wall viscosity” estimates obtained using dynamic elasticity as well as the magnetization curve and the coefficient of static elasticity is carried out. The significance of the results obtained for ‘magnetoviscous’ effect for performing diagnosis of interparticle aggregation is indicated.
Evaluation of the Residual Strength of Structures Made of Composite Materials Based on a Conservative Distribution of Damage Parameters
Authors: Fedulov B N , Fedorenko A N , Lomakin E V 
Published: July 2019

Abstract
The purpose of this study is to develop the method that conservatively estimates the residual strength of a composite structure with barely visible impact damage (BVID), without direct modelling of impact process. The basis of the research is in the conservative transformation of kinetic energy of impactor into damage of the material, which is associated with the system of microcracks in the matrix, fiber and interface. A special algorithm that distributes damage parameters in worst way for the composite structure provides conservative estimation of residual strength. Thus, bvid allowables can be set using fewer experiments.

Published: July 2019

Abstract
This work presents a study of the hydrodynamics of gas bubbles in a magnetic fluid which is in a flat channel with a thickness of 2 mm, placed in the non-uniform field of the rare-earth annular permanent magnet. The peculiarity of the magnetic field configuration of this magnet is as follows: at a distance of 9 mm from the surface of the magnet there are two symmetric regions where the magnetic field is zero, the so-called ‘magnetic vacuum’ regions. The specified configuration of the magnetic field allows capturing and holding gas cavities when the magnet moves; while pressing the cavity to the bottom of the channel, gas bubbles separate. An experimental setup was created to study the hydrodynamics of gas inclusions; using this setup studies on the concentration series of four magnetic fluids based on kerosene with a volume concentration of 10.56 %; 6.32 %; 3.93 % and 2.08% were conducted. The mechanism of gas bubbles capturing and gas cavity formation in a magnetic fluid in the magnetic vacuum region of an annular magnet is investigated. The process of the separation of the bubbles from the air cavity when it is pressed down to the bottom of the channel by a non-uniform magnetic field is studied.

Abstract
The solution of a wide range of tasks of protection and rational use of water bodies requires, first of all, an assessment of the levels of impact of industrial complexes. The solution of such problems for extreme technological and hydrometeorological conditions is carried out on the basis of appropriate computational experiments. However, verification of the underlying mathematical models can be performed only on the basis of correct input data. The paper presents materials of field studies of the temperature distribution of water both in the water area and in the depth of the Magnitogorsk reservoir, in the zone of influence of thermal effluents of PJSC “Magnitogorsk Iron and Steel Works” (PJSC MMK). It is shown that in the warmest limiting period, a significant vertical temperature inhomogeneity is formed.

Seeds of change: characterizing the soil seed bank of a migrating salt marsh
Authors: Kottler Emily J , Gedan Keryn 
Published: July 2019

AbstractBackground and AimsThe capacity for dispersal to promote or hinder species’ responses to global change remains a major question in ecology. One ecosystem experiencing rapid change is the tidal marsh, which is migrating inland in response to accelerated sea level rise. Few studies to date have investigated the ecological dynamics that impact this large-scale migration. Seed dispersal and persistence in the soil seed bank is a component that can be strongly indicative of community trajectories. With this in mind, the aim of our study was to characterize the germinable seed bank across a marsh–forest ecotone in the Chesapeake Bay.MethodsSoil samples were collected across transects that ran from the high marsh to the coastal loblolly pine forest in a brackish marsh in Blackwater National Wildlife Refuge, MD, USA. Samples were grown in a greenhouse and watered with either freshwater or 3 ppt seawater solution. We compared community composition across transects and between salinity treatments. Additionally, we compared the seed bank with standing vegetation and used seed trait data from the TRY Database to investigate changes in functional traits along this ecotone.Key ResultsWe found halophytic species dispersing up to 15 m into the forest and a general lack of obligate upland species, including near absence of Pinus taeda, the dominant species in the forest canopy. A majority of species detected in the seed bank were wetland species of various types, with species with wide salinity tolerance arising most frequently. Salinity addition had a significant negative influence on seed bank diversity.ConclusionOverall, our seed bank results suggest that dispersal and germination under the conditions of saltwater intrusion will limit forest regeneration and favour marsh plant dispersal. This indicates that the ecological processes that determine the soil seed bank community will support continued migration of marsh species into uplands.
Hydration Interventions for older people living in residential and nursing care homes: overview of the literature
Authors: Cook Glenda , Hodgson Philip , Thompson Juliana , Bainbridge Lesley , Johnson Amy , Storey Paul 
Published: July 2019

Abstract

Introduction
Care home populations experiencing high levels of multi-morbidity and dementia require support from caregivers to meet their hydration requirements. This article provides an overview of literature related to hydration interventions and highlights gaps in knowledge.

Sources of data
This paper draws on UK-focused literature from Applied Social Sciences Index and Abstracts (ASSIA), CINAHL, Medline, Proquest Hospital Premium Collection, Cochrane Library and RCN databases on hydration interventions for older people living with multi-morbidity and dementia in care homes.

Areas of agreement
Fluid intake is too low in care home residents, and no single hydration intervention is effective in addressing the complex problems that older residents present.

Areas of controversy
There is a lack of consensus about how much fluid an older person should consume daily for optimum health. There is also lack of agreement about what interventions are effective in supporting individuals with complex physical and cognitive problems to achieve daily fluid intake targets.

Growing points
To improve hydration care for residents, care home teams should be competent in the delivery of hydration care, and work closely with integrated multi-professional healthcare specialists to provide proactive case management.

Areas timely for developing research
There is a need for understanding of what hydration practices and processes are effective for care home residents and including these in multi-component interventions.
The Application of Connectome-Based Predictive Modeling to the Maternal Brain: Implications for Mother–Infant Bonding
Authors: Rutherford Helena J V , Potenza Marc N , Mayes Linda C , Scheinost Dustin 
Published: July 2019

Abstract
Maternal bonding early postpartum lays an important foundation for child development. Changing brain structure and function during pregnancy and postpartum may underscore maternal bonding. We employed connectome-based predictive modeling (CPM) to measure brain functional connectivity and predict self-reported maternal bonding in mothers at 2 and 8 months postpartum. At 2 months, CPM predicted maternal anxiety in the bonding relationship: Greater integration between cerebellar and motor–sensory–auditory networks and between frontoparietal and motor–sensory–auditory networks were associated with more maternal anxiety toward their infant. Furthermore, greater segregation between the cerebellar and frontoparietal, and within the motor-sensory-auditory networks, was associated with more maternal anxiety regarding their infant. We did not observe CPM prediction of maternal bonding impairments or rejection/anger toward the infant. Finally, considering 2 and 8 months of data, changes in network connectivity were associated with changes in maternal anxiety in the bonding relationship. Our results suggest that changing connectivity among maternal brain networks may provide insight into the mother–infant bond, specifically in the context of anxiety and the representation of the infant in the mother’s mind. These findings provide an opportunity to mechanistically investigate approaches to enhance the connectivity of these networks to optimize the representational and behavioral quality of the caregiving relationship.

AbstractOBJECTIVESThe purpose of this study was to describe pre- and postoperative data from the EUROMACS registry with regard to indications, for and survival and complication rates of patients with primary continuous flow and pulsatile biventricular long-term assist devices (BiVADs) versus total artificial hearts (TAHs) or left ventricular assist devices (LVADs) + short-term right ventricular assist device (RVAD) implants.METHODSWe investigated patients who received implants between 1 January 2011 and 21 October 2017. Clinical baseline information about comorbidities, laboratory results, medical and device therapies and echocardiographic, haemodynamic and right ventricle (RV) parameters were evaluated along with the rates of deaths and complications.RESULTSA total of 413 of 3282 patients (12.5%) needed a biventricular pump. We investigated 37 long-term BiVADs, 342 LVAD + short-term RVAD implants and 34 TAHs. Minor differences were found in the baseline characteristics of our population, which had an overall high morbidity profile. The 1-year survival rate was 55% for patients with a continuous flow BiVAD; 52% for patients with an LVAD + short-term RVAD; 37% for patients with pulsatile BiVADs; and 36% for patients with a TAH. No statistical difference was observed among the groups. Over 50% of patients with BiVAD support were classified as INTERMACS profiles 1 and 2. The percent of patients with ambulatory heart failure (INTERMACS 4‒7) undergoing BiVAD implants was modest at <15%. No patients with a pulsatile BiVAD (n = 15) or a TAH (n = 34) were implanted as destination therapy, but 27% of the patients with continuous flow BiVADs (n = 6) and 23% of the patients with LVAD + short-term RVAD (n = 342) were implanted as ‘destination’. The adverse events profile remained high, with no significant difference among pump types. The right ventricular stroke work index and right heart failure scores indicated poor RV function in all groups. After 3 months of LVAD + short-term RVAD support, 46.7% still required ongoing support, and only 18.5% were weaned from RVAD support; 33.1% died.CONCLUSIONSThe mortality rate after BiVAD support was high. Survival rates and adverse events were statistically not different among the investigated groups. In the future, composite study end points examining quality of life and adverse events beyond survival may help in shared decision-making prior to general mechanical circulatory support, particularly in patients with BiVAD implants.

Abstract

Background
We report on the impact of two system-level policy interventions (the Long-Term Care Homes Act [LTCHA] and Public Reporting) on publicly reported physical restraint use and non-publicly reported potentially inappropriate use of antipsychotics in Ontario, Canada.

Methods
We used interrupted time series analysis to model changes in the risk-adjusted use of restraints and antipsychotics before and after implementation of the interventions. Separate analyses were completed for early ([a] volunteered 2010/2011) and late ([b] volunteered March 2012; [c] mandated September 2012) adopting groups of Public Reporting. Outcomes were measured using Resident Assessment Instrument Minimum Data Set (RAI-MDS) data from January 1, 2008 to December 31, 2014.

Results
For early adopters, enactment of the LTCHA in 2010 was not associated with changes in physical restraint use, while Public Reporting was associated with an increase in the rate (slope) of decline in physical restraint use. By contrast, for the late-adopters of Public Reporting, the LTCHA was associated with significant decreases in physical restraint use over time, but there was no significant increase in the rate of decline associated with Public Reporting. As the LTCHA was enacted, potentially inappropriate use of antipsychotics underwent a rapid short-term increase in the early volunteer group, but, over the longer term, their use decreased for all three groups of homes.

Conclusions
Public Reporting had the largest impact on voluntary early adopters while legislation and regulations had a more substantive positive effect upon homes that delayed public reporting.
