Flexural, pull-out, and fractured surface characterization for multi-material 3D printed functionally graded prototype

This paper reports the flexural, pull-out, and fractured surface characterization for multi-material three-dimensional printed functionally graded prototypes, which is prepared on fused deposition modeling setup. The work is an extension of previously reported study in which different thermoplastic matrices of polylactic acid blended with polyvinyl chloride, wood dust, and Fe3O4 powder (as multiple blended feedstock filaments) have been prepared separately with twin screw extrusion for possible three-dimensional printing. Finally, functionally graded prototypes with alternative layers of polylactic acid (01 layer), polylactic acid + polyvinyl chloride (01 layer), polylactic acid + wood dust (02 layers), and polylactic acid + Fe3O4 (02 layers) were three-dimensional printed on fused deposition modeling for flexural samples as per ASTM D790. With regard to process parameters of fused deposition modeling (in this case study), infill density of 100%, infill angle of 45°, and infill speed of 50 mm/s were the optimized processing conditions. The results of study suggest that maximum flexural strength 26.92 MPa and pull-out strength 18.11 MPa were observed for functionally graded multi-material three-dimensional printed prototypes. From fractured surface analysis and hardness result, it has been ascertained that higher infill density and lower infill angle lead to better diffusion of material in layer-by-layer fashion resulting into less void formation and better flexural and pull-out performances. The novelty of this work lies in accessing the behavior of three-dimensional printed prototypes having different functional ability for each layer, with a potential to replace hybrid blend-based prototypes.
Effect Evaluation of the Integration of Citizen Science Activities into Environmental Education Project Design: A Case Study of the Spring Swallow Survey Project

Citizen science is a process that seeks to involve the public in scientific projects through systematic data collection and observations of natural phenomena. Environmental education centres on the relationship between humans and nature and has attracted the attention of more and more educators because of its increasingly important educational value. This paper reports an empirical study on environmental education projects featuring observations of natural phenomena and using local environmental resources. Using the Spring Swallow Survey project as an example, the design ideas and evaluation framework for the project are analysed. The implementation effect of the project is examined quantitatively and qualitatively. Finally, the resource package used in the project is revised and redeveloped according to the effect evaluation data.
Incidência de endometrite citológica e desempenho reprodutivo em vacas de corte Nelore (Incidence of cytological endometritis and its effects on reproductive performance in Nelore beef cows)

Were evaluated the incidence of cytological endometritis from 29 to 90 days postpartum and its effect on the reproductive performance of Nelore beef cows submitted to a breeding season (BS) for 90 days. A total of 49 cows, with no history of retained placenta, without the presence of a clinic uterine infection, and with a body condition score above 2.5 were used. Ultrasound examination was performed to evaluate the uterine wall and ovarian activity. The cytological diagnosis of endometritis was done by uterine lavage, and endometritis was considering cases of ≥5% neutrophils in each blade. The incidence of cytological endometritis in the herd was 22%, and did not differ between the categories analyzed (primiparous versus multiparous) (P>0.05), and the conception rate for first insemination was also similar between primiparous versus multiparous (P>0.05). However, the pregnancy rate at the end of BS was higher in multiparous cows (83.8%) when compared to primiparous (50.0%) cows (P 0.05) nor pregnancy rate at the end of the BS (P>0.05). Therefore, it can be concluded that the use of endometrial cytological cannot be justified as a diagnostic tool in Nelore beef cows.
Recurrence after anatomic versus nonanatomic resection for hepatocellular carcinoma: a Meta-analysis

Objective To compare anatomic resection (AR) and non-anatomic resection (NAR)for hepatocellular carcinoma (HCC) as a factor in preventing intra-hepatic recurrence and local recurrence after the initial surgical procedure.Methods A systematic review and Meta-analysis of nonrandomized trials comparing anatomic resection with non-anatomic resection for HCC published from 1990to 2010 in PubMed and Medline,Coehrane Library,Embase,and Science Citation Index were searched.Intra-hepatic recurrence,including early and late recurrence,and local recurrence were primary outcomes.5-year survival and 5-year disease-free survival were secondary outcomes.Pooled effect was calculated by utilizing either fixed effects model or random effects model.Result Eleven nonrandomized studies including 1576 patients were identified and analyzed.810 patients were in the AR group and 766 were in the NAR group.Patients in the AR group were characterized by lower prevalence of cirrhosis,more favorable hepatic function,and larger tumor size and higher prevalence of macrovascular invasion compared with patients in the NAR group.Anatomic resection significantly reduced the risks of local recurrence (OR,0.27; 95％ CI,-0.17～0.43; P＜0.001) and achieved a better 5-year disease-free survival (OR,2.10; 95％ CI,-1.41 ～3.12; P=0.001) in HCC patients.Also,anatomic resection was marginally effective in decreasing early intra-hepatic recurrence.However,anatomic resection was not advantageous in preventing late intra-hepatic recurrence.No significant differences were found between the AR and NAR groups with respect to postoperative morbidity,mortality,and length of hospitalization.Conclusion Anatomic resection was recommended to be superior to non-anatomic resection in reducing the risks of local recurrence,early intra-hepatic recurrence and achieving a better 5-year disease-free survival in HCC patients. Key words: Hepatocellular carcinoma; Anatomic resection; Non-anatomic resection; Intrahepatic recurrence; Early recurrence

Electoral Vulnerability, Party Affiliation, and Dyadic Constituency Responsiveness in U.S. Legislatures

It is often argued that electoral vulnerability is critical to constituency responsiveness. We investigate this possibility using different measures of vulnerability, but argue that in the United States the Republican Party may be less responsive than the Democratic Party due to its core constituency and view of representation. We test our hypotheses relying on an innovative research design that exploits referenda in U.S. states to compare legislator voting behavior with voter preferences on exactly the same policy proposal, allowing us to overcome the measurement problems of much previous research. Based on a newly compiled data set of more than 3,000 voting decisions for 818 legislators on 27 referenda, we find high levels of congruence, but that congruence with the median voter is higher for legislators who are running for reelection. We also find that Democrats are more responsive after a close election but that Republicans are not sensitive to electoral margins.
Development of Analytical Tools and Animal Models for Studies of Small-Intestine Dysbiosis

Our appreciation of the role of human-associated microbial communities in the context of human health and disease has grown dramatically in the past two decades, with modern research tools enabling deeper insights into the mechanisms of host-microbial interactions. The elusive notion of dysbiosis, a state of microbial imbalance related to a disease, has achieved widespread distribution across popular, scientific, and medical literature (on September 16, 2019 PubMed search yielded 6,064 records of scientific and medical publications containing this keyword). The conventional wisdom further narrows down the definition and understanding of dysbiosis towards a compositional "imbalance" of the microbiota (a community of all microorganisms inhabiting human body). There exists an additional and frequently overlooked aspect of microbial imbalance in the context of the human gastrointestinal system, something that we can define as a "spatial imbalance": a state of the microbial community in the host gastrointestinal system where even a "healthy" and "balanced" microbiota may be associated with or causative of a disease by being present in sections of the gastrointestinal tract where it is not "supposed" to be, with the most prominent example being small intestinal bacterial overgrowth (SIBO). This thesis describes the progress in the development of analytical tools (quantitative microbiome profiling described in Chapter I) and refinement of animal mouse models (non-coprophagic mouse model described in Chapter II) for exploring the normal function of small-intestine microbiota in health and for dissecting the mechanisms of emergence and the persistence of the small-intestine dysbiosis (SIBO) in the future.
HVdc Reactor Reduction Method Based on Virtual Reactor Fault Current Limiting Control of MMC

A large high-voltage direct current (HVdc) reactor is required in modular multilevel converter (MMC) projects to realize dc fault current limiting (FCL). This condition may result in adverse effects on MMC control dynamics and oscillation and instability of HVdc systems. In this article, a virtual reactor (VR) control strategy is proposed to reduce a fixed large HVdc reactor. The VR characteristic of MMCs is revealed and analyzed as a controlled reactor, and the inductance of this reactor can be directly controlled by the discharge degree of submodule capacitors. A virtual reactor fault current limiting (VRFCL) control strategy in which VR can effectively limit dc fault current and substitute the fixed HVdc reactor is proposed accordingly. Simulation and experimental results verify the proposed control strategy. The adoption of the proposed strategy can eliminate the undesirable effect caused by an HVdc reactor, and the sub-module (SM) capacitor voltage can be reserved well. In addition, fault clearance time and fault energy dissipation can be reduced. The proposed VRFCL control is beneficial for MMCs to safely ride through dc fault in a continuous operation manner.
Nature of Cretaceous dolerite dikes with two distinct trends in the Damodar Valley, eastern India: Constraints on their linkage to mantle plumes and large igneous provinces from 40Ar/39Ar geochronology and geochemistry

Two distinct sets of Cretaceous dolerite dikes intrude the Chhotanagpur gneissic complex of eastern India, mostly within the Damodar Valley Gondwanan sedimentary basins. One dike set trends NNE to ENE, whereas the other set, which includes the prominent Salma dike, trends NW to NNW. One dike from each set in the Raniganj Basin was dated using the 40Ar/39Ar method in order to resolve a controversy concerning the emplacement age of the Salma dike. The NE-trending dike yielded a plateau age of 70.5 ± 0.9 Ma, whereas the NNW-trending Salma dike is much older, with a plateau age of 116.0 ± 1.4 Ma. These results demonstrate that the Salma dike was emplaced at ca. 116 Ma and not at ca. 65 Ma, as suggested in an earlier study. Geochemical characteristics of the two dikes are also distinct and indicate that they belong to previously identified high-Ti and low-Ti dolerite groups, respectively. The observed geochemical characteristics of both dike sets are comparable with the geochemistry of basalts of the Kerguelen Plateau, Bunbury Island, and Rajmahal Group I and suggest a connection to mantle plumes. The new age data presented herein indicate that these two magmatic episodes in the eastern Indian Shield were related to the ca. 120–100 Ma Kerguelen mantle plume and its associated Greater Kerguelen large igneous province and the ca. 70–65 Ma Réunion plume and its associated Deccan large igneous province, respectively.
A Hybrid Simulation Modelling Framework for Combining System Dynamics and Agent-Based Models

System dynamics (SD), discrete event simulation (DES) and agent-based model (ABM) are three different simulation modelling methods widely applied to support decision-making in complex systems across various disciplines. However, single simulation modelling approaches can face significant challenges representing the multi-dimensional nature of complex systems composed of interactive and interconnected constituents with dynamic behaviours. Combining different simulation methods offer an opportunity to overcome these challenges and to capture important characteristics and behaviours of such systems. Despite the growing interest and popularity in this approach, guidance for designing and utilizing hybrid models, especially for those combining SD and ABM, is scanty. This paper aims to review and consolidate the existing theoretical guidance/frameworks on combining these two simulation methods. Based on this literature review, we propose an initial framework for combining SD and ABM.
The Potential of Applying Collaborative Learning Strategy via the Internet
to Collect, Correct, and Create Educational Content in Higher Education

ABSTRAT Specialists in the field of education calling that student is the focus of the educational process to create self-knowl - edge and then to engage in an educational environment that will earn good learning achievement. Therefore, the importance of the present study is to identify the benefits of teamwork through the internet with students of higher education to search for information and construct of educational content whilst being supervised by a faculty mem - ber. The present study investigates the potential of applying a collaborative learning strategy over the internet among a sample of students in higher education. The sample was selected from different universities within the Kingdom of Saudi Arabia. The researcher used and developed Gilly Salmon’s five stage model of e-learning as the learning model and as a way for measuring students’ activities via the internet. The sample consisted of 24 postgraduate stu - dents (10 females and 14 males in the age group of 22–26 years) from 13 Saudi universities. The data were collected during the first term of the academic year 2016-2017. In order to analyse the data, the researcher employed content analysis patterns using qualitative data analysis software, NVivo. The results showed that students participated actively with each other, particularly after the second week. The quality of student information collected varied depending on the ability of each student to use the internet. Students explained some of the obstacles that prevented them from using the internet in collaborative learning and to the importance of providing students with the internet skills when searching for information. In addition, the study sug - gests that ‘large groups’ of students using the internet should consist of a minimum number of 15 students. Finally, efforts should be made to conduct training courses in e-learning organized and managed by experts in e-learning, in order to provide students with the requisite background knowledge.
Language choice and identity construction of Azerbaijani bilinguals in family and friendship domains

ABSTRACT This study investigates Azerbaijani bilinguals’ language choice and identity construction processes in family and friendship domains. Individual interviews were conducted with 19 (11 male, 8 female) participants. The emerged themes were classified under three categories, i.e. age, gender and language ideologies. The findings revealed that language attitudes and ideologies are the main reason for Azerbaijani bilinguals’ language choice in family and friendship domains. Farsi as the national language and the only language of education is considered important symbolic power compared to Azerbaijani Turkish language. The findings of the study also showed that age and gender in family domain and gender in friendship domain are influential factors in Azerbaijani bilinguals’ language choice. Azerbaijani bilingual females use Azerbaijani Turkish to speak to their older family members while they choose Farsi to speak to other family members. Azerbaijani bilingual males choose Azerbaijani Turkish to speak to their older family members, their brothers and their male friends but they speak in Farsi to their female family members and female friends as well as their children. The findings and implications are discussed in detail.
Health, prevention and economics.

Prevention is better than cure, it is said, but is it more efficient? In the quest for improvements in health and life expectancy, and reductions in the growth of health care costs, attention has focused on the cost-effectiveness of preventive over curative medicine. Economics adds an essential dimension to the analysis of prevention policy that extends far beyond the study of comparative costs. The aim of this book is to give, for the first time, a comprehensive overview of the economics of prevention. It examines the scope of economics; the impact of the economy on avoidable ill-health, and of prevention on the economy; the economic rationale for provision of preventive services and regulation of hazardous activities; the cost-benefit approach and the nature of efficiency in prevention; the practice of economic appraisal; economic influences on the demand for hazardous commodities and screening services; theories of preventive behaviour; national prevention programme budgeting and priority setting; and the potential contribution of health economics.
Dyonic and Magnetic Black Holes with Rational Nonlinear Electrodynamics

The principles of causality and unitarity are studied within rational nonlinear electrodynamics proposed earlier. We investigate dyonic and magnetized black holes and show that in the self-dual case, when the electric charge equals the magnetic charge, corrections to Coulomb's law and Reissner-Nordstrom solutions are absent. In the case of the magnetic black hole, the Hawking temperature, the heat capacity and the Helmholtz free energy are calculated. It is shown that there are second-order phase transitions and it was demonstrated that at some range of parameters the black holes are stable.
Iron-Doped Titanium Dioxide Nanoparticles As Potential Scaffold for Hydrazine Chemical Sensor Applications

Herein, we report the fabrication of a modified glassy carbon electrode (GCE) with high-performance hydrazine sensor based on Fe-doped TiO2 nanoparticles prepared via a facile and low-cost hydrothermal method. The structural morphology, crystalline, crystallite size, vibrational and scattering properties were examined through different characterization techniques, including FESEM, XRD, FTIR, UV–Vis, Raman and photoluminescence spectroscopy. FESEM analysis revealed the high-density synthesis of Fe-doped TiO2 nanoparticles with the average diameter of 25 ± 5 nm. The average crystallite size of the synthesized nanoparticles was found to be around 14 nm. As-fabricated hydrazine chemical sensors exhibited 1.44 μA µM−1 cm−2 and 0.236 µM sensitivity and limit of detection (LOD), respectively. Linear dynamic ranged from 0.2 to 30 µM concentrations. Furthermore, the Fe-doped TiO2 modified GCE showed a negligible inference behavior towards ascorbic acid, uric acid, glucose, SO42−, NO3−, Pb2+ and Ca2+ ions on the hydrazine sensing performance. Thus, Fe-doped TiO2 modified GCE can be efficiently used as an economical, easy to fabricate and selective sensing of hydrazine and its derivatives.
Heuristics for a berth allocation problem with additional constraints on the movement of the quay cranes

This thesis explores the berth allocation and crane assignment problem, with in particularly the heuristics and meta-heuristics construction heuristic, local refinements, squeaky wheel optimisation, tabu search and simulated annealing. The speed and cost are examined and it is found that the tabu search is the best performing meta-heuristic. Further, the movement of the quay cranes are restricted along a rail so that the different quay cranes cannot pass each other. A scenario where maintenance needs to be done on a quay crane is also explored.
Factors affecting quality of life in cancer patients undergoing chemotherapy.

BACKGROUND Cancer can produce many different symptoms, some subtle and some not at all subtle. An increasingly important issue in oncology is to evaluate quality of life (QoL) in cancer patients. The cancer-specific QoL is related to all stages of this disease. OBJECTIVE The aim of this study was to evaluate the QoL in cancer patients with solid tumors and at the different chemotherapy cycles (CT). METHODS This was a cross-sectional study. A total of 200 cancer patients were included. With some modification, the European Organization for Research and Treatment of Cancer QoL Questionnaire (EORTC QLQ-C30) was used to measure QoL in the patients. The QoL in most subjects (66%) was fairly favorable. RESULTS A significant relationship between the cancer type, pain intensity, and fatigue was found. However, none of the demographic variables (age, education, marital status, income) were significantly related to QoL. Nevertheless, significant difference was found between the level of QoL in patients with ≤ 2 CT cycles and/or with 3-5 cycles (p< 0.001). CONCLUSION Cancer is an important health issue influencing QoL. An appropriate treatment which may provide care to the cancer patients is CT. A CT cycle may improve QoL in patients with solid tumors.
Performansi Implementasi Paralel OpenMP pada Persamaan Air Dangkal 2D untuk Simulasi Gelombang Runup

Terdapat banyak aliran dangkal di alam seperti tsunami, aliran banjir, aliran pada sungai, pasang surut air laut, dan sebagainya. Aliran dangkal dapat disimulasikan dengan menggunakan Persamaan Air Dangkal atau Shallow Water Equations (SWE). Salah satu fenomena nonlinear yang penting dalam aliran dangkal adalah fenomena runup. Khususnya untuk menyimulasikan fenomena runup secara akurat, perlakuan khusus pada implementasi numerik dari model gelombang harus dilakukan. Pada artikel ini, persamaan SWE diimplementasikan dengan metode Finite Volume pada grid komputasi dengan model momentum conservative staggered grid. Untuk meningkatkan performasi komputasi terutama untuk menyimulasikan domain komputasi yang besar dengan resolusi grid tinggi, pada paper ini skema numerik tersebut diimplementasikan dengan metode arsitektur OpenMP. Performansi algoritma paralel dikuantifikasi dengan menghitung speedup dan efisiensi. Dari hasil paralelisasi tersebut, didapatkan efisiensi pada waktu komputasi untuk kasus-kasus dengan jumlah grid komputasi yang besar.
