Cell-Laden Thermosensitive Chitosan Hydrogel Bioinks for 3D Bioprinting Applications

Three-dimensional (3D) bioprinting is a technology used to deposit cell-laden biomaterials for the construction of complex tissues. Thermosensitive hydrogels are physically cross-linked by non-covalent interaction without using crosslinkers, facilitating low cytotoxicity and cell viability. Chitosan, which is a non-toxic, biocompatible and biodegradable polysaccharide, can be used as a thermosensitive hydrogel. Therefore, chitosan hydrogel could be of potential use as a 3D bioprinting ink. The purpose of this study was to develop and compare the effectivity of different bioinks based on chitosan hydrogels for 3D bioprinting. The solvent type did not affect the gel shape and gelation time, whereas acetic acid exhibited better biocompatibility compared to lactic and hydrochloric acids. The nature of the gelling agent was found to have a stronger influence on these characteristics than that of the solvent. The NaHCO3 moiety exhibited a higher growth rate of the storage modulus (G′) and a more irregular porous structure than that of the β-glycerophosphate (β-GP) and K2HPO4 groups. Cell viability, and live and dead assays, showed that the NaHCO3 group was more efficient for cell adhesion. The type of gelling agent did not lead to appreciable differences in cell-laden constructs. The NaHCO3 group was more amenable to bioprinting, compared to the β-GP and K2HPO4 groups. The chitosan hydrogel bioinks could, therefore, be good candidates for 3D bioprinting and would pave the way for patient-specific regenerative medicines.
The Effects of Subculture on The Mutant Plant Regeneration of Rodent Tuber (Typhonium flagelliforme) In Vitro Mutagenesis Using Gamma-Ray Irradiation

The combination of gamma-ray irradiation treatment and somaclonal variation may cause morphological changes in vitro culture of rodent tuber. In vitro shoots were irradiated with several gamma-ray doses. Rodent tuber plantlets were irradiated with the doses of 20 Gy. The plantlets were subcultured up to 5 times then produced MV1 to MV5. Plantlets MV4 and MV5 were acclimatized and transplanted at the greenhouse. The purpose of this study was to analyze the morphological characteristics in the fourth mutant vegetative propagation (MV4) and the fifth mutant vegetative propagation (MV5) of rodent tuber from the combination of gamma-ray irradiation and somaclonal variation. Subcultures were performed to regenerate from MV1 to MV5 with optimal MS (Murashige & Skoog) medium. Subcultures were done at eight weeks. The morphological measurement in MV4 with the average number of shoots, number of leaves and plant height, i.e. 5.21, 14.41 and 5.52 cm, respectively. The highest average number of shoots, number of leaves and plant height was generated in MV5, i.e. 5.23, 16.54 and 5.18 cm, respectively. Pre-acclimatization were successfully produced in the greenhouse of about 30% (MV4) and 39.5% (MV5). Post acclimatization was obtained 100% in control, MV4, and MV5 at the greenhouse. MV5 had better morphological characteristics. The morphological changes were occurring in MV4 and MV5 compared with controls due to the combination of gamma-ray irradiation and somaclonal variation.
New Paradigm of Lean Six Sigma in the 4th Industrial Revolution Era

Purpose: In early 2000s Six Sigma and Lean were combined into Lean Six Sigma (LSS), which has been one of the major strategic quality initiatives all over the world. Now, we are in the era of the 4th Industrial Revolution (IR), which changes almost everything including LSS and quality management (QM) in the companies. We need new paradigm of LSS to boost LSS activities in this 4th IR era. In this paper, the typical characteristics of the 4th IR are investigated, and desirable new paradigm of LSS is presented. Methodology/Approach: The changing characteristics of production strategy, quality goal and quality strategy with regard to QM in the 4th IR are discussed and presented. Then the new and emerging paradigm of LSS in this 4th IR era is discussed in detail. Also 9 success factors for this new paradigm of LSS are shown for practitioners in the industry. Findings: The direction of the new paradigm of LSS will be ‘simple, speedy and smart’, which may be called ‘3S paradigm’. Simple open procedures and simple statistical modelling tools will be mainly used. Speedy on-site improvement based on Open Data, Big Data and artificial intelligence (AI) will be favoured. Also smart mass customized ‘Smart Factory’ method will be emphasized. Research Limitation/implication: Since we are in the beginning stage of the 4th IR, there are not many research papers which study the impact of this revolution to LSS and QM, which is the major research limitation. Originality/Value of paper: This paper suggests some new and emerging paradigm of LSS, which could be of high value.
Biocontrol del moho foliar del tomate Cladosporium fulvum empleando cuatro hongos antagonistas

Leaf mold Cladosporium fulvum (Cooke 1883), produce a tomato crop disease under greenhouse in Peru. As an alternative to control this pathogen the efficiency under in vitro conditions and greenhouse conditions of four antagonistic fungi was probed: Hansfordia pulvinata Berk y Curt 1958, Trichoderma harzianum (Rifai 1969), T. viride (Persoon 1821) and T. virens (Miller, Giddens y Foster 1963). Fungal culture and growth was performed in Agar Sabouraud for Trichoderma spp. and in Agar Juice V8 for H. pulvinata. The bioassay employed was precolonized plates proposed by Krauss. In in vitro conditions was observed that at 24°C and 72 h growing of T. harzianum was statistically different than the other three species tested, and at 28°C was similar to T. viride. At 120 h and 24°C growing of T. virens was different from all species evaluated. At 168 h growing of the three species of Trichoderma, were statistically similar, varying from H. pulvinata. At 28°C and at 120 h and 168 h the results were statistically similar to the three species of Trichoderma, but different to H. pulvinata. Micoparasitism is the most common-action mechanism. Finally, T. harzianum was the most efficient antagonistic fungus because reduced disease in 19.35% under greenhouse conditions.
Genetic Analysis of Development and Behavior in Hypoxia and Cellular Characterization of Anoxia Induced Meiotic Prophase Arrest in Caenorhabditis Elegans

It was hypothesized that chronic hypoxia will affect various biological processes including developmental trajectory and behavior. To test this hypothesis, embryos were raised to adulthood in severe hypoxic environments (0.5% O2 or 1% O2, 22°C) and analyzed for survival rate, developmental progression, and altered behaviors. Wildtype hermaphrodites survive chronic hypoxia yet developmental trajectory is slowed. The hermaphrodites raised in chronic hypoxia had different phenotypes in comparison to the normoxic controls. First, hermaphrodites exposed to chronic hypoxia produced a significantly lower number of embryos and had a slight increase in male progeny. This suggests that chronic hypoxia exposure during development affects the germline. Second, animals raised in chronic hypoxia from embryos to young adults have a slight increase in lifespan when re-exposed to a normoxic environment, indicating that chronic hypoxia does not negatively decrease lifespan. Finally, hermaphrodites that were raised in hypoxia will lay the majority of their eggs on the area of the agar plate where the bacterial lawn is not present. This is in contrast to animals in normoxia, which lay the majority of their eggs on the bacterial lawn. One hypothesis for this hypoxia-induced egg-laying behavior is that the animal can sense microenvironments in hypoxia. To examine if various pathways are involved with chronic-hypoxia responses RNAi and assayed genetic mutants were used. Specifically, genetic mutations affecting oxygen sensing (egl-9), aerotaxis (npr-1), TFG-s signaling (dbl-1, daf-7) and predicted oxygen-binding proteins (globin-like genes) were phenotypically analyzed. Results indicate that mutations in several of these genes (npr-1, dbl-1) resulted in a decrease in hypoxia survival rate. A mutation in egl-9 also had a detrimental affect on the viability of an animal raised in chronic hypoxia. However, a similar phenotype was not observed in the vhl-1 mutation indicating that the phenotype may not be due to a mere increase in HIF-1 levels, per se. A mutation in the globin-like gene (glb-13(tm2825)) suppressed the hypoxia-induced egg-laying phenotype. That is, the glb-13(tm2825) animal raised in chronic hypoxia laid eggs on the bacterial lawn at a significantly higher rate in comparison to wildtype controls, thus suggesting that globin-like molecules may be involved with the sensing of microenvironments. Together, this research lays the foundation for understanding the implications of chronic hypoxia in developing organisms.
Shape Loss of Autoclaved, Machine-Bent Cobalt-Chrome and Titanium Spine Surgery Rods

Study Design: This was a biomechanical study. Objective: Shape loss of surgical spine rods has been implicated as a factor leading to postsurgical loss of alignment correction. Our objective was to compare the degree of shape loss in surgical spine rods of different compositions under physiological conditions that were bent before or after being autoclaved. Methods: 10 CoCr and 10 commercially pure titanium (CPTi) surgical spine rods were contoured using a machine press. Five CoCr and 5 CPTi rods were bent before being autoclaved (preoperative bent group); 5 CoCr and 5 CPTi rods were bent after being autoclaved (intraoperative bent group). All rods were immersed in a phosphate-buffered saline bath at body temperature (37.2°C ± 2°C). Changes in radius of curvature were measured at different time intervals over an 8-week course using a high-definition scanner. Results: Each rod demonstrated shape loss in radius of curvature (range = 1.04-9.99 mm) over the duration of the study. Intraoperatively bent CPTi rods demonstrated the largest shape loss (range = 8.73-9.99 mm; median 9.33 mm; P < .01). Preoperatively bent CPTi (range = 1.04-1.71 mm; median = 1.39 mm; P < .01) and intraoperatively bent CoCr (range = 1.11-2.11 mm; median = 2.01 mm; P < .01) rods underwent the least amount of shape loss. Conclusion: CPTi spinal rods bent after autoclave may lead to considerable loss of alignment correction. In addition, our results suggest that preautoclave bent CPTi and CoCr spinal rods bent after autoclave may be a more ideal choice of implant because they may provide more resistance to shape loss over time.
Decision Tree Method Using for Fetal State Classification from Cardiotography Data

The motive of the investigation is analyzing the categorization of fetal state code from the Cardiographic data set based on decision tree method. Cardiotocography is one of the important tools for monitoring heart rate, and this technique is widely used worldwide. Cardiotocography is applied for diagnosing pregnancy and checking fetal heart rate state condition until before delivery. This classification is necessary to predict fetal heart rate situation which is belonging. In this paper, we are using three input attributes of training data set quoted by LB, AC, and FM to categorize as normal, suspect or pathological where NSPF variable is used as a response variable. After drawing necessary analysis into three variables we get the 19 nodes of classification tree and also we have measured every single node according to statistic, criterion, weights, and values. The Cardiotocography Dataset applied in this study is received from UCI Machine Learning Repository. The dataset contains 2126 observation instances with 22 attributes. In this experiment, the highest accuracy is 98.7%. Overall, the experimental results proved the viability of Classification and Regression Trees and its potential for further predictions.This is an Open Access article distributed under the terms of the Creative Commons Attribution License (http://creativecommons.org/licenses/by/4.0/), which permits unrestricted use, distribution, and reproduction in any medium provided the original work is properly cited.

Design and Analysis of Oil-Immersed Cooling Stator With Nonoverlapping Concentrated Winding for High-Power Ironless Stator Axial-Flux Permanent Magnet Machines

Ironless stator axial-flux permanent magnet (AFPM) machines provide many attractive electromagnetic performances such as high efficiency in high-frequency mode and strong short-term overload ability, which make them more competitive in flywheel energy storage applications. However, designing high-torque-density AFPM machines, particularly their ironless stators, is with significant challenges and needs great efforts. In this article, a high-strength oil-immersed cooling stator with nonoverlapping concentrated winding is proposed for high-power ironless stator AFPM machine applications. This article explains in detail the design, analysis, and manufacturing process of the proposed oil-immersed cooling stator. With the three-dimensional finite-element analysis (3-D FEA), a 9000-r/m/50-kW 12-slot/10-pole prototype for a flywheel energy storage system is successfully designed and developed using the proposed high-strength oil-immersed cooling ironless stator. The experimental test results demonstrate the effectiveness of the cooling design and mechanical strength.
Framing the Narrative: Female Fighters, External Audience Attitudes, and Transnational Support for Armed Rebellions

Female combatants play a central role in rebel efforts to cultivate and disseminate positive narratives regarding the movement and its political goals. Yet, the effectiveness of such strategies in shaping audience attitudes or generating tangible benefits for the group remains unclear. We propose and test a theory regarding the channels through which female fighters advance rebel goals. We argue that female fighters positively influence audience attitudes toward rebel groups by strengthening observers’ beliefs about their legitimacy and their decision to use armed tactics. We further contend that these effects directly help them secure support from transnational nonstate actors and indirectly promote state support. We assess our arguments by combining a novel survey experiment in two countries with analyses of new cross-national data on female combatants and information about transnational support for rebels. The empirical results support our arguments and demonstrate the impact of gender framing on rebel efforts to secure support.
Psychometric Properties of Questionnaires for Assessing Chronotype

The concept of chronotype refers to inter-individual differences for preferred time of day to be active or to sleep. Chronotype needs to be considered to lie on a continuum from extreme morning-types to extreme evening-types [1]. Morning-types (MT) go early to bed and wake up early, and perform at their best mental and physical performance in the early part of the day. In contrast, evening-types (ET) sleep and wake up late, and achieve their peak performance in the later of the day and evening hours. About 40% of adults fall in to one of the two extreme circadian types, whereas most people belong in the middle part of continuum [1]. Chronotype is also known as several different terminologies such as morningness-eveningness preference [2], circadian typology [3]. Chronotype can be measured by various self-administered questionnaires, which have been validated in many different languages. Accurate measurement is essential in all academic fields.

VEGF-incorporated PVDF/collagen nanofibrous scaffold for bladder wall regeneration and angiogenesis

Abstract A common problem encountered with tissue-engineering constructs is the lack of adequate angiogenesis in newly produced tissue. We compared biocompatibility and expression level of apoptotic and angiogenesis-related gene markers in the primary bladder smooth muscle cells (HBdSMC) and human umbilical vein endothelial cells (HUVEC) when grown on the intact and VEGF-loaded scaffolds that were made of polyvinylidene fluoride and collagen. It was found an increased protein adsorption, cell attachment, and viability in VEGF-loaded scaffold compared to the intact scaffold. In addition, apoptotic and angiogenesis-related genes downregulation and upregulation were also detected in HBdSMC and HUVEC while grown on the VEGF-loaded scaffold, respectively. GRAPHICAL ABSTRACT
Maneuvering Target Tracking Based on Multiple-model Multipath Bernoulli Filter

Aiming at the problem of maneuvering single target tracking in over the horizon radar system under the clutter environment, a novel multiple-model multipath Bernoulli filter (MM-MPBF) algorithm is proposed. First, the multipath target measurement model is established based on the finite set statistics, and then combining the multiple models method with the multipath Bernoulli filter to deal with the single maneuvering target tracking problem in over the horizon radar system. Finally, the simulation experiment is used to verify the performance of the MM-MPBF algorithm.
Electrically Active Defects in Polycrystalline and Single Crystal Metal Halide Perovskite

We studied electrically active defects in CsPbBr3 polycrystalline films and single crystals samples using the thermally stimulated currents (TSC) technique in the temperature range 100–400 K. Below room temperature, both polycrystalline and single-crystals TSC emission is composed by a quasi-continuum of energy levels in the range 0.1–0.3 eV, and capture cross sections ~10−21 cm2. Above room temperature, TSC analysis reveals the presence of defect states in the range 0.40–0.52 eV only in polycrystalline samples, whereas these intermediate energy states are absent in TSC detected in single crystals. In polycrystalline films, the occupancy changes of an energy level at 0.45 eV strongly influences the room temperature photoconductivity, giving rise to slow transients due to defect passivation. In single-crystals, where intermediate energy states are absent, the photoconductivity response during illumination is almost stable and characterized by fast rise/decay times, a promising result for future applications of this material in photodetection and dosimetry.
Monitorizarea sistemului și a log-urilor pentru Data Hub Software (DHuS)

Many technology projects fail to be successful, one of the reasons being the lack of monitoring. It is on one hand the lack of system monitoring, which may cause hardware and kernel vulnerabilities, and on the other hand, the lack of applications and services monitoring, which may cause unsatisfied users with the outcome of the project. We propose the monitoring of DHuS, used for downloading sentinel data, which is important once because the system handles large sets of data and once because it is useful to see the user's interest in the provided services. The solution has two components, one of system monitoring and the other of log monitoring. Both results in sending data to graphical interfaces, hoping that the users of those two components may be able to improve the project based on the information provided.
Increase OEE at Manual Assembly Lines by Data Mining

The industrial companies often use Key Performance Indicators (KPI) to follow up and evaluate their process and success. One of the KPIs is the Overall Equipment Effectiveness (OEE) which represents the efficiency of the manufacturing area. The high OEE value means good performance of the machines or lines. This paper presents a method in order to increase OEE at the manual assembly lines by data mining. Firstly, a literature review demonstrates scientific relevance. Secondly, a method is introduced for improving the efficiency with the help of the recognised patterns. Using Manufacturing Execution System (MES) data the OEE percentage was increased by 8% in 3 months without any financial investment.
Wildfire Smoke Detection Based on Depthwise Separable Convolutions and Target-Awareness

Since smoke usually occurs before a flame arises, fire smoke detection is especially significant for early warning systems. In this paper, a DSATA(Depthwise Separability And Target Awareness) algorithm based on depthwise separability and target awareness is proposed. Existing deep learning methods with convolutional neural networks pretrained by abundant and vast datasets are always used to realize generic object recognition tasks. In the area of smoke detection, collecting large quantities of smoke data is a challenging task for small sample smoke objects. The basis is that the objects of interest can be arbitrary object classes with arbitrary forms. Thus, deep feature maps acquired by target-aware pretrained networks are used in modelling these objects of arbitrary forms to distinguish them from unpredictable and complex environments. In this paper, this scheme is introduced to deal with smoke detection. The depthwise separable method with a fixed convolution kernel replacing the training iterations can improve the speed of the algorithm to meet the enhanced requirements of real-time fire spreading for detecting speed. The experimental results demonstrate that the proposed algorithm can detect early smoke, is superior to the state-of-the-art methods in accuracy and speed, and can also realize real-time smoke detection.
Customer participation risk management: conceptual model and managerial assessment tool

PurposeCustomer participation (CP) has received considerable interest in the service literature as a way to improve the customer experience and reduce service providers' costs. While its benefits are not in question, there is a paucity of research on potential pitfalls. This paper provides a conceptual foundation to address this gap and develops a comprehensive model of the risks of customer participation in service delivery, integrating research from the marketing, operations and supply chain management, strategy, and information technology fields.Design/methodology/approachThe model is derived deductively by integrating insights from research in marketing, operations and supply chain management, strategy, and information technology.FindingsThis paper identifies three categories of potential risks of CP (i.e. market, operational, and service network) and discusses ways that firms can mitigate these risks. Building on the model, it develops a CP risk assessment tool that managers can use when evaluating increases in CP.Research limitations/implicationsThe conceptual model proposed in this paper can serve as a robust basis for future research in customer participation, particularly in such areas as sharing economy services, service delivery networks, and experiential services. The risk assessment tool offers clear guidelines for managers who are considering an increase in customer participation in their service.Originality/valueThis is the first attempt to conceptually define customer participation risk and develop a comprehensive model of its drivers and strategies to mitigate it. This paper develops a straightforward method for managers to evaluate CP risk.
