Establishment of primary cell lines from tissues of the red-eared slider

Primary cell lines of the red-eared slider were established from somatic slider tissues cultivated in appropriate medium for a certain period. Exponential cell growth started after 2 weeks of continuous cultivating. The cells were of various morphology resembling keratinocytes, fibroblasts, and melanocytes, some of them gathered to form dense conglomerates similar to so-called “embryoid bodies”. The cell lines were maintained for 3–7 passages before being taken for cytogenetic manipulations. Red-eared slider cell lines derived in this way can be cryopreserved and successfully recovered to provide a source of fixed cells for 3D imaging as well as a source of chromosomes and chromatin fiber preparations for cytological and cytogenetic studies. The protocol for red-eared slider cells was developed on the basis of the experiments described.
The Impact of Implementing Electronic Workforce Management System in Hamad Medical Corporation on Nursing Staff Management

Despite of the benefits of implementing an integrated workforce management system in healthcare setting, having a system capable of processing staff data, facilitating patient assignment according to acuity level and the nursing workload, there is no enough evidenced based data on the improvements and gains of the transformation from previous staffing practices to a comprehensive workforce Management system. The purpose of this study is to assess impact of implementing the Work force Management System in enhancing the effectiveness of staffing management and the level of end user satisfaction compared to the previous workflow. A quantitative study design was adopted where a questionnaire survey was conducted with 113 nursing managers and 231 staff nurses who approved to participate in the research. The survey tools were divided to two parts; part1 to survey nursing managers and part 2 to survey the staff nurses. Findings revealed that automating staffing management has positive impact on the nurses manager staffing management practice as 80.5% agreed on the effectiveness of workforce management system and 74.9% of staff nurses are generally satisfied with the system. In conclusion, the Interoperability of workforce management system may result in higher satisfaction rate but it increases the need for continuous training and familiarization in addition to close system monitoring and optimization. Thus, in order to achieve effective scheduling, optimal utilization of staffing, and fair distribution of assignments with consideration of patient acuity level, it is recommended to develop a competency based training framework in order to improve using the system by end users as required in addition developing workforce system performance optimization plan to ensure the system is effectively performing.
Hierarchical assembly of DNA origami nanostructures using coiled-coil peptides.

DNA and peptides are two of the most commonly used biomolecules for building self-assembling materials, but few ex-amples exist of hybrid nanostructures that contain both components. Here we report the modification of two peptides that comprise a coiled-coil heterodimer pair with unique DNA handles in order to link DNA origami nanostructures bear-ing complementary strands into micrometer-long one-dimensional arrays. We probed the effect of number of coils on self-assembly and demonstrated the formation of self-assembled structures through multiple routes: one-post assembly, formation of dimers and trimers and an alternating copolymer of two different origami bundles, and stepwise assembly of purified structures with coiled-coil conjugates. Our results demonstrate the successful merging of two distinct self-assembly modes to create hybrid bionanomaterials expected to have a range of potential applications in the future.
Effects of nutrition education on cardio-metabolic outcomes: A randomised clinical trial

Objective: The aim of this study was to assess the effect of Full Plate Diet (FPD) on the primary prevention of cardio-metabolic risk factors. Design: Randomised clinical trial. Setting: Drayson Center, Loma Linda University, CA, USA. Methods: Forty individuals were randomly assigned to either an intervention group receiving the FPD health education for 10 weeks or to a control group not receiving this intervention. Comprehensive evaluations of clinical and anthropometric outcomes were conducted at baseline and at the end of intervention. To assess within-group changes and between-group differences, a general linear model was used. Results: Significant reductions in weight (−1.54 kg, 95% confidence interval [CI] −2.5, −.54) and total cholesterol (TC) (−11.7 mg/dL; 95% CI −21.4, −2) and non-significant reductions in means for low-density lipoprotein cholesterol (LDL-C) (−7.3 mg/dL, 95% CI −16, 1.5) and triglycerides (−18.7 mg/dL, 95% CI −46, 8.5) were observed in the intervention group after 10 weeks compared with baseline. These reductions were non-significantly higher in the intervention compared with the control group. There were no significant mean changes in systolic and diastolic blood pressure, high-density lipoprotein cholesterol (HDL-C) and haemoglobin A1c (A1c) in the intervention group after 10 weeks. Conclusion: A multi-component programme comprising 10 weeks of health education that emphasised the high intake of fibre failed to significantly reduce cardio-metabolic risk factors. It did show a downward trend in triglycerides, TC and body weight that may be of clinical importance suggesting that a future investigation with a longer intervention duration is needed.
EFFECT OF THE ASYMMETRICAL AXIAL DISPLACEMENT OF TRANSFORMER WINDINGS ON FRA CHARACTERISTICS

Frequency response analysis (FRA) is one of the most reliable and useful methods for mechanical fault detection in transformers. The winding axial displacement is one of the mechanical fault types that can occur in transformers. Axial displacements causes the detailed model parameters changing, in response to which FRA characteristics will also change. Numerous researchers have considered winding axial displacements as a symmetrical movement of disks. However, one of the most prevalent types of winding axial displacements is asymmetrical axial displacement which has not been considered by any prior studies. In this paper, physical asymmetrical and symmetrical axial displacements of the first disk of the LV winding were simulated and FRA characteristics were obtained for these cases. Finally, experimental tests were performed on an experimental transformer to validate the simulation results.
Exploring How Rivals and Complementors Affect Evolutionary Rate of B2C Apps: An Empirical Study

: The hyper competition among rivals and enveloping threats from complementors are crucial external sources that influence app update strategies of B2C platforms. However, prior app-related literature largely focuses on factors affecting app performance, with scant attention on external drivers of the continuous app evolution, that is app updates. Besides, the results of app updates on market performance are mixed in extant literature. Therefore, this study is motivated to explore how competitive pressures from rivals and enveloping threats from complementors affect evolutionary rate of B2C apps and its subsequent effects on market performance. Our empirical study demonstrates that quick evolution of rival and complementor apps increases evolutionary rate of B2C apps. In contrast, a greater number of better performed rival and complementor apps decreases the evolutionary rate. Furthermore, we unveiled an inverted U-shaped relationship between evolutionary rate of B2C apps and market performance. The theoretical implications are also discussed.

Hypotheses were tested using factor analysis, reliability and multiple regression analysis. The result of this study reveals the CSFs that significantly influence the successful implementation of LSS within the TELCO industry. The study identified project selection, prioritization and reviews the most critical to the success of implementing the LSS program, which eventually will enhance supply chain performance in TELCO industry. The result from this study provides valuable insight and knowledge to telecommunication firms on how to improve their understanding on the implementation of Lean Six Sigma and enhance supply chain performance in a developing country, Malaysia.
3-D P-wave velocity structure of oceanic core complexes at 13°N on the Mid-Atlantic Ridge

The Mid-Atlantic Ridge at 13° N is regarded as a type locality for oceanic core complexes (OCCs), as it contains, within ∼70 km along the spreading axis, four that are at different stages of their life cycle. The wealth of existing seabed observations and sampling makes this an ideal target to resolve contradictions between the existing models of OCC development. Here we describe the results of P-wave seismic tomographic modelling within a 60 × 60 km footprint, containing several OCCs, the ridge axis and both flanks, which determines OCC crustal structure, detachment geometry and OCC interconnectivity along axis. A grid of wide-angle seismic refraction data was acquired along a series of 17 transects within which a network of 46 ocean-bottom seismographs was deployed. Approximately 130,000 first arrival travel times, together with sparse Moho reflections, have been modelled, constraining the crust and uppermost mantle to a depth of ∼10 km below sea level. Depth slices through this 3-D model reveal several independent structures each with a higher P-wave velocity (Vp) than its surrounds. At the seafloor, these features correspond to the OCCs adjacent to the axial valley walls at 13°20′N and 13°30′N, and off axis at 13°25′N. These high-Vp features display dipping trends into the deeper crust, consistent with the surface expression of each OCC's detachment, implying that rocks of the mid-to-lower crust and uppermost mantle within the footwall are juxtaposed against lower Vp material in the hanging-wall. The neovolcanic zone of the ridge axis has systematically lower Vp than the surrounding crust at all depths, and is wider between OCCs. On average, throughout the 13° N region, the crust is ∼6 km-thick. However, beneath a deep lava-floored basin between axial OCCs the crust is thinner and is more characteristically oceanic in layering and velocity-depth structure. Thicker crust at the ridge axis suggests a more magmatic phase of current crustal formation, while modelling of the sparse Moho reflections suggests the crust-mantle boundary is a transition zone throughout most of the 13° N segment. Our results support a model in which OCCs are bounded by independent detachment faults whose dip increases with depth and is variable with azimuth around each OCC, suggesting a geometry and mechanism of faulting that is more complicated than previously thought. The steepness of the northern flank of the 13°20′N detachment suggests that it represents a transfer zone between different faulting regimes to the south and north. We propose that individual detachments may not be linked along-axis, and that OCCs act as transfer zones linking areas of normal spreading and detachment faulting. Along ridge variation in magma supply influences the nature of this detachment faulting. Consequently, not only does magma supply control how detachments rotate and migrate off axis before finally becoming inactive, but also how, when and where new OCCs are created.
Estimation of crack width based on shape‐sensitive kernels and semantic segmentation

Cracks that develop in railway infrastructural components such as tunnel linings and track systems are not easy to detect on high‐speed rail routes, since inspection time is limited during the daytime and visibility is very poor at night. Meanwhile, cracks to structures such as those above mentioned are strictly monitored and treated to prevent possible malfunction or accident. In this regard, a track measurement vehicle is normally deployed to image track components and measure geometric information. The main goal of the present study was to detect cracks in images and to simultaneously measure the maximum crack width by means of newly introduced deep learning technology. For this, a shape‐sensitive kernel, that is, crack‐like kernel, within a semantic segmentation framework and a modified deep layer model were proposed. In addition to the conventional statistical models such as accuracy and intersection over union, the predicted results of the proposed models were verified by considering the boxplot and root mean square errors of the estimated crack widths. According to the results, the proposed shape‐sensitive kernel function was able to predict crack width more precisely by one or two pixels than the conventional semantic segmentation model. Future work will concentrate on the integration of the crack detection model with deterioration prediction of track geometry in order to enable systematic decision making for the predictive maintenance of railway systems.
Fundamental Insights from a Single‐Crystal Sodium Iridate Battery

Electrochemically driven chemical transformations play the key role in controlling storage of energy in chemical bonds and subsequent conversion to power electric vehicles and consumer electronics. The promise of coupling anionic oxygen redox with cationic redox to achieve a substantial increase in capacities has inspired research in a wide range of electrode materials. A key challenge is that these studies have focused on polycrystalline materials, where it is hard to perform precise structural determinations, especially related to the location of light atoms. Here a different approach is utilized and a highly ordered single crystal, Na2−xIrO3 is harnessed, to explore the role of defects and structural transformations in layered transition metal oxide materials on redox‐activity, capacity, reversibility, and stability. Within a combined experimental and theoretical framework, it is demonstrated that 1) it is possible to cycle Na2−xIrO3, offering proof of principle for single‐crystal based batteries 2) structural phase transitions coincide with Ir 4+/Ir 5+ redox couple with no evident contribution from anionic redox 3) strong irreversibility and capacity fade observed during cycling correlates with the Na + migration resulting in progressive growth of an electrochemically inert O3‐type NaIrO3 phase.
An investigation on tube hydroforming process considering the effect of frictional coefficient and corner radius

ABSTRACT Tube hydroforming (THF) technology is mostly used in automotive and aerospace industries because of its benefits like high precision, less weight and forming capability of complex shapes. Formability of the tube is the main factor for the consideration of the THF technologies in the industries. Thickness distribution in the bulged area is the key factor for the consideration of hydroformed parts. In the present paper, effects of coefficient of friction and corner radius of the die on bulge height and thickness distribution of the bulged area are studied using finite element method. Mechanical properties required to carry out the numerical simulations are evaluated by tensile, R-bar and pin-on-disc tests. Pin-on-disc experiments are carried out on the chosen material to find the wear and frictional coefficient with varying normal loads. Both numerical and analytical solutions are compared for the internal pressure required to bulge and burst the tube and observed to be in good agreement with each other. This study helps the researchers and industrialists for further understanding of the mechanics involved in the THF process in terms of die design and frictional effects.
Information-theoretically secure three-party computation with One corrupted party

The problem in which one of three pairwise interacting parties is required to securely compute a function of the inputs held by the other two, when one party may arbitrarily deviate from the computation protocol (active behavioral model), is studied. An information-theoretic characterization of unconditionally secure computation protocols under the active behavioral model is provided. A protocol for Hamming distance computation is provided and shown to be unconditionally secure under both active and passive behavioral models using the information-theoretic characterization. The difference between the notions of security under the active and passive behavioral models is illustrated by examining a protocol for computing quadratic and Hamming distances that is secure under the passive model, but is insecure under the active model.
Efficacy of Development Control as a Tool for Monitoring Building Developments in Kenya

Received: Feb 15, 2019 Revised: Mar 6, 2019 Accepted: Mar 23, 2019 This study examined the efficacy of development control in the monitoring of building developments in Kenya, a case study of Kisii Town. It focused on the extent to which the 1968 Building Code was enforced by the County Government of Kisii in an attempt to promote quality assurance. The target population comprised 7,430 residential developments from where a sample size of 364 was proportionately and randomly drawn. Research findings indicated that 39% of developers were unaware that their developments should have been inspected during construction. Similarly, awareness of building inspection significantly predicted if developers issued Notices of Inspection to the planning authority to facilitate inspections. Consequently, developers who were unaware that their building constructions required inspection were 99.9% less likely to issue such notices. Moreover, developers who did not obtain development permission were correspondingly 99.9% less likely to issue Inspection Notices. As a result, those who did not issue Notices of Inspection were 99.8% less likely to have their buildings inspected during construction due to lack of records indicating when such constructions had commenced. The study concludes that although the County Government of Kisii is lawfully mandated to monitor building developments in Kisii Town, the function is not well executed. This gap affords developers with an opportunity of not conforming to the approved building plans.
Quantity over Quality? Perception of Designating Long-Term Care Hospitals as Providers of Hospice and Palliative Care

Purpose: Amendment to the Act on Decisions on Life-sustaining Treatment was recently enacted to designate long-term care hospitals as providers of hospice and palliative care. Despite its benefit of providing improved accessibility to end-of-life care, the amendment has raised concerns about its effect on quality of service. This study aimed to use information obtained from an expert group interview and previous studies to compare how cancer patients, family caregivers, physicians, and the general Korean population perceive the potential benefits and risks of this amendment. Methods: We conducted a multicenter cross-sectional study from July to October 2016. The included participants answered a structured questionnaire regarding the extent to which they agree or disagree with the questionnaire items indicating the potential benefits and risks of the amendment. Chi-square tests and univariate and multivariate logistic regression analyses were performed. Results: Compared with the general population, physicians agreed more that long-term care hospitals are cur-rently not adequately equipped to provide quality hospice and palliative care. Family caregivers found improved access to long-term care hospitals more favorable but were more likely to agree that these hospitals might prioritize profits, thereby threatening the philosophy of hospice care, and that families might cease to fulfill filial responsibilities. Compared with the general population, cancer patients were more concerned about the potentially decreased service quality in this setting. Conclusion: Although potential service beneficiaries and providers expected improved accessibility of hospice and palliative care services, they were also concerned whether the system can provide adequate quality of end-of-life care.

FUZZY MODELING OF VERBAL INFORMATION FOR PRODUCTION SYSTEMS

FUZZY MODELING OF VERBAL INFORMATION FOR PRODUCTION SYSTEMS The subject of the article's research is the formalization of unstructured or semistructured verbal information for a fuzzy production system. The purpose of the work is to develop a method of constructing membership functions for fuzzy sets of terms of a linguistic variable that will allow formalizing unstructured or semistructured verbal information for fuzzy production systems. The following tasks are solved in the article: to develop a method of constructing the membership functions to determine the sequence of stages: the stage of modeling verbal information in the form of digraphs, the stage of constructing the order relation on the elements of this model, the step of determining a linguistic variable based on the created model, and determining the functions of fuzzy sets of linguistic terms variable. Methods are used: graph theory, mathematical induction, fuzzy modeling. Results obtained: a method for constructing the membership function of linguistic variables that formalizes unstructured or semi-structured qualitative information for fuzzy production systems is developed. For this purpose, the process of constructing the membership function has been broken down into stages. The implementation of the first stage requires the creation of a model of unstructured or semistructured verbal information. Three models of information based on oriented trees are considered with increasing complexity. A model based on an acyclic oriented graph is considered as a generalization. Such a model is the basis for processing information that has a structure of greater complexity. The second stage provides a theoretical basis for constructing the order relation for the elements of the models under consideration. For the implementation of the third stage, a method of identifying the order elements on the basis of the positional system is proposed. Based on the ID of each ordered element, functions of fuzzy sets of terms of a linguistic variable are constructed. Appropriate procedures have been developed to implement the steps. Conclusions : application of the method will allow automating the assignment of vectors of input and output information, to automate the formation of fuzzy sets of terms of the corresponding linguistic variables, will allow to build fuzzy products as a knowledge base of a fuzzy production system, and to train such a system.
