3D Microprinting of Iron Platinum Nanoparticle-Based Magnetic Mobile Microrobots

Wireless magnetic microrobots are envisioned to revolutionize minimally invasive medicine. While many promising medical magnetic microrobots are proposed, the ones using hard magnetic materials are not mostly biocompatible, and the ones using biocompatible soft magnetic nanoparticles are magnetically very weak and, therefore, difficult to actuate. Thus, biocompatible hard magnetic micro/nanomaterials are essential toward easy‐to‐actuate and clinically viable 3D medical microrobots. To fill such crucial gap, this study proposes ferromagnetic and biocompatible iron platinum (FePt) nanoparticle‐based 3D microprinting of microrobots using the two‐photon polymerization technique. A modified one‐pot synthesis method is presented for producing FePt nanoparticles in large volumes and 3D printing of helical microswimmers made from biocompatible trimethylolpropane ethoxylate triacrylate (PETA) polymer with embedded FePt nanoparticles. The 30 μm long helical magnetic microswimmers are able to swim at speeds of over five body lengths per second at 200 Hz, making them the fastest helical swimmer in the tens of micrometer length scale at the corresponding low‐magnitude actuation fields of 5–10 mT. It is also experimentally in vitro verified that the synthesized FePt nanoparticles are biocompatible. Thus, such 3D‐printed microrobots are biocompatible and easy to actuate toward creating clinically viable future medical microrobots.
Three-dimensional geomechanical model of creep behavior on wellbore casing in the composite salt–gypsum formation

According to statistics, a certain proportion of the world’s oil and gas resources are stored under the salt rock in the sedimentary basin. These reservoirs are located in formations called “pre-salts,” which are below the salt formations. They are widely found in the Sichuan, Tarim, and Changqing oilfields and in West Africa, offshore Brazil, the Gulf of Mexico, and the North Sea. The salt–gypsum layer exhibits a rheological property, which has a significant influence on casing damage. Creep deformation of the composite salt–gypsum formation occurs over time. Moreover, it applies excess stress on the wellbore casing, which can lead to casing damage. In this study, triaxial experiments are conducted on samples of salt–gypsum composite rock, and a power-law creep constitutive model is created. In the experiment, room temperature and humidity conditions are applied. Three types of loading, including axial and confining pressures, are separately applied on the samples, including the confining pressure (5 MPa) and the axial pressures (20, 25, and 30 MPa). From the experimental results, the relation between creep strain and time can be obtained, and a power-law creep model can be matched as the constitutive equation, which indicates that the strain rate is dependent on differential stress and temperature. The Abaqus finite element method software is used for establishing a 3D geomechanical model with formation stress and wellbore pressure to evaluate the life expectancy of wellbore casing. According to the triaxial rock experiment in the laboratory and according to field data, the mechanical parameters of the salt–gypsum formation and the parameters of the pre-salt reservoir are obtained, respectively. The results demonstrate that the von-Mises stress on the wellbore casing in the salt–gypsum layer increases during the production period. Meanwhile, the creep deformation of the formation also increases and applies extra loading on the casing, which is prone to exceed the strength and damage. Moreover, in this research, the discontinuous stress and deformation at the interface of the composite salt–gypsum formation, on which few researchers have studied until now, can be quantitatively described. The results indicate that the stress on the wellbore casing in the pre-salt layer is different, that is, the stress abruptly changes at the interface between pre-salt and salt–gypsum formation. The results also show the discontinuous creep deformation at the interface and that the casing is prone to shear collapse. Considering the sudden change in the stress at the interface of the formation is important. These results can be utilized to establish a casing design and for the analysis of wellbore integrity. For instance, the composite salt–gypsum layer should pass through the design of the double-layer casing and enable the thick-walled casing to increase its strength.
Public Acceptance of Driverless Buses in China: An Empirical Analysis Based on an Extended UTAUT Model

Driverless buses are expected to play a vital role in the future, and better public acceptance will provide a social foundation for its development. In this study, two new variables, personal innovativeness (PI) and perceived risk (PR), were incorporated into the integrated technology acceptance model (UTAUT, unified theory of acceptance and use of technology) to construct an extended model, which was then applied to explore the influencing factors for the public acceptance of driverless buses. The quality of this extended model was verified through survey data collected in Chongqing, China. The structural equation modeling (SEM) method was adopted to quantitatively describe the impact of each factor on acceptance intention (AI) as well as the mutual influence relationships between the factors. The moderating effects of demographic attributes (gender, age, and education level) on each factor in the model were also analyzed. The results showed that PI and PR are the most critical factors that affect the public’s acceptance intention; effort expectancy (EE), performance expectancy (PE), social influence (SI), and facilitating condition (FC) can also determine the acceptance intention to a certain extent; gender, age, and education level have exhibited significantly different moderating effects on the influencing factors. The explanatory power of the current research model for acceptance intention has reached 48%. This study has confirmed the applicability of the extended UTAUT model to the research of driverless bus acceptance and the research outcomes can serve as a reference basis for improving the service quality of driverless buses in China.
Remix this method: a creative approach to young people’s everyday lives as political arenas

ABSTRACT Young people’s everyday lives are not just social and cultural environments, but also political arenas (Kallio and Häkli. 2011. ‘Are there politics in childhood? ’ (Space & Polity 15 (1): 21–34, 2). A methodological approach is proposed that emphasizes young people’s knowledge, while accepting the power and privilege of the researcher. By way of illustration, this paper demonstrates how an approach to co-creation of the method, inspired by the idea of a remix or a bricolage, can provide creative tasks as stimuli for the discussion of politics but also legitimizing mechanisms for young expertise and co-creation in the research site itself as a political arena. Specifically, this paper examines how young participants responded to a digital photography task by subverting the task itself, a process which allowed them to remix the model, making them simultaneously in control of the task and dependent upon it. This complex outcome was constructive as a way to stimulate participants as they explored their everyday lives as political arenas.
A Meta-Synthesis of Policy Recommendations Regarding Human Mobility in the Context of Climate Change

Changing mobility patterns combined with changes in the climate present challenges and opportunities for global health, requiring effective, relevant, and humane policy responses. This study used data from a systematic literature review that examined the intersection between climate change, migration, and health. The study aimed to synthesize policy recommendations in the peer-reviewed literature, regarding this type of environmental migration with respect to health, to strengthen the evidence-base. Systematic searches were conducted in four academic databases (PubMed, Ovid Medline, Global Health and Scopus) and Google Scholar for empirical studies published between 1990–2020 that used any study design to investigate migration and health in the context of climate change. Studies underwent a two-stage protocol-based screening process and eligible studies were appraised for quality using a standardized mixed-methods tool. From the initial 2425 hits, 68 articles were appraised for quality and included in the synthesis. Among the policy recommendations, six themes were discernible: (1) avoid the universal promotion of migration as an adaptive response to climate risk; (2) preserve cultural and social ties of mobile populations; (3) enable the participation of migrants in decision-making in sites of relocation and resettlement; (4) strengthen health systems and reduce barriers for migrant access to health care; (5) support and promote optimization of social determinants of migrant health; (6) integrate health into loss and damage assessments related to climate change, and consider immobile and trapped populations. The results call for transformative policies that support the health and wellbeing of people engaging in or affected by mobility responses, including those whose migration decisions and experiences are influenced by climate change, and to establish and develop inclusive migrant healthcare.
Screening of antibiofilm activity and toxicity assay of methylotrophic bacteria compounds isolated from the human mouth

Biofilm is a community consisting of one or more species of bacteria attached to a surface using a matrix. Biofilms can cause health problems in humans, such as dental plaque. Biofilm is one form of self-defense of bacteria against antibiotics, so biofilm often has implications for the rise in resistance of bacteria. Therefore, antibiofilm compounds can be used to increase the sensitivity of bacteria to the antimicrobial agent. The purpose of this study is to determine the antibiofilm activity and the potential toxicity of the methylotrophic bacteria compound isolated from the human mouth. Based on the results of the study, 21 out of 37 isolates of methylotrophic bacteria had antibiofilm activity using two different supernatant concentrations (5% and 10%). The isolate of M28L2 showed the highest anti-biofilm inhibition activity: 47.64% against EHEC and 50.97% against Pseudomonas aeruginosa ATCC 27583. Meanwhile, M30G1 isolate showed the highest anti-biofilm destruction activity: 44.062% against EHEC and 39.17% against ETEC. Toxicity test was performed on five isolates that had the highest antibiofilm activity using a lethal dose test. Based on these test results, five isolates had LC50 values greater than 1000μg/mL, indicating that the compound was not toxic. Subsequently, PCR amplification for the DNA sequencing stage was performed on one isolate, M28L2. Based on the sequencing results, M28L2 had a 99% similarity to Pseudomonas stutzeri.
Sensitive Liquid Crystal‐based Sensor for Monitoring the Enzymatic Activities of Trypsin

In this study, a highly sensitive and label‐free method was developed to monitor the enzymatic activities of trypsin via orientational transition of liquid crystals (LCs) coupled to the interactions between the polyelectrolyte and phospholipid monolayer. Generally, the positively charged polyelectrolyte interacted with the negatively charged phospholipid monolayer by electrostatic interaction, which caused reorganization of the phospholipid membrane and induced a homeotropic to planar orientational transition of LCs. Enzymatic cleavage of the polyelectrolyte, which was caused by trypsin, eliminated the electrostatic interaction that occurred at the aqueous/LC interface and restored the LC alignment. The optical response of the LC changed in a way that corresponded with the LC molecular arrangement, which enables naked‐eye detection under polarized optical microscopy. A rather low detection limit, down to 10 ng/mL, was achieved for trypsin activity detection by applying the proposed method.
Constraints on Martian Chronology from Meteorites

Martian meteorites provide the only direct constraints on the timing of Martian accretion, core formation, magmatic differentiation, and ongoing volcanism. While many radiogenic isotope chronometers have been applied to a wide variety of Martian samples, few, if any, techniques are immune to secondary effects from alteration and terrestrial weathering. This short review focuses on the most robust geochronometers that have been used to date Martian meteorites and geochemically model the differentiation of the planet, including 147Sm/143Nd, 146Sm/142Nd, 176Lu/176Hf, 182Hf/182W, and U-Th-Pb systematics.
Influences, Views and Practices Associated with Life Skills Education for Children with Autism in Two Cities in Turkey and England

ABSTRACT This study explored influences, views and practices associated with life skills education for children with autism within schools in two cities in England and in Turkey of similar socio-economic status and size. Data was collected via interviews with staff and observations in mainstream and special schools. Life skills were taught to children with autism in both cities. Schools in both cities taught basic and complex everyday skills, associated with psychosocial abilities, and enhancement of positive behaviour. The teaching of life skills was influenced by cultural and religious views and availability of resources resulting in differing models. In the Turkish Schools development of life skills relied more heavily on situational learning within the community as a bridge to parental engagement, whereas the English schools were more likely to use an adapted experiential model within the school campus with support from parents in transferring skills at home.
Universal Design for Learning (UDL) Across Cultures: The Application of UDL in Kuwaiti Inclusive Classrooms

The purpose of this qualitative study was to investigate the role of Universal Design for Learning (UDL) in inclusive settings in which students with and without disabilities learn and gain knowledge. Five teachers from Kuwait participated in the study. Twenty-five consecutive observations were conducted to derive the primary data for this study. Interviews with the teachers were also used to support/add to the study’s results. Findings indicate that UDL is effective in engaging all students, including those with disabilities. The results also found that although teachers may have basic knowledge of UDL, they need more training and practice to successfully address the needs of all students, including students with disabilities.
Deep Learning in Selected Cancers’ Image Analysis—A Survey

Deep learning algorithms have become the first choice as an approach to medical image analysis, face recognition, and emotion recognition. In this survey, several deep-learning-based approaches applied to breast cancer, cervical cancer, brain tumor, colon and lung cancers are studied and reviewed. Deep learning has been applied in almost all of the imaging modalities used for cervical and breast cancers and MRIs for the brain tumor. The result of the review process indicated that deep learning methods have achieved state-of-the-art in tumor detection, segmentation, feature extraction and classification. As presented in this paper, the deep learning approaches were used in three different modes that include training from scratch, transfer learning through freezing some layers of the deep learning network and modifying the architecture to reduce the number of parameters existing in the network. Moreover, the application of deep learning to imaging devices for the detection of various cancer cases has been studied by researchers affiliated to academic and medical institutes in economically developed countries; while, the study has not had much attention in Africa despite the dramatic soar of cancer risks in the continent.
Effects of job autonomy on workplace loneliness among knowledge workers

Purpose Given its detrimental implications for employees’ well-being and work performance, this paper seeks to understand how workplace loneliness occurs by focusing on a job-related antecedent, job autonomy. Drawing on role identity theory and situational strength theory, the purpose of this paper is to propose that job autonomy relates to workplace loneliness via perceived insider status, a process moderated by perceived clan culture. Design/methodology/approach A two-wave survey served to collect data from 430 knowledge workers in 17 enterprises from several major cities in Eastern China. Findings Job autonomy relates to workplace loneliness via the mediation of perceived insider status. Specifically, job autonomy impacts positively on perceived insider status, which further reduces workplace loneliness. Besides, the relationship between perceived insider status and workplace loneliness is conditional on perceived clan culture – perceived insider status decreases workplace loneliness more effectively in the case of higher perceived clan culture. Furthermore, perceived clan culture moderates the mediating effect of perceived insider status. Originality/value This paper is among the few attempts to offer a comprehensive framework in which job and organizational characteristics combine to explain workplace loneliness. Moreover, the findings illustrate that perceived insider status and perceived clan culture complement each other in alleviating workplace loneliness.
MICROBIALLY-MEDIATED METHYL IODIDE CYCLING IN A PARTICLE-RICH ESTUARY

The dynamics of aquatic systems (e.g. estuarine systems) are known to facilitate the formation of particle aggregates. These nutrient-rich particulate matter provide suitable substrate for bacteria colonization. Although bacteria-aggregate association is known to result in the degradation of particulate organic matter (POM) in aquatic systems, it has never been attributed to the production of methyl iodide (CH31) (an environmentally important biogas that has the potential to impact on atmospheric chemistry). From literature, there are evidences which suggest that, certain bacteria (methylotrophs) are capable of oxidizing methyl halides including CH31. Therefore this study investigates microbial production and removal of CH31 in estuarine water through their association with aggregates and assesses the effect of physicochemical variables on bacterial-mediated production and removal of CH31. From the study, bacteria-aggregate processes were found to elevate the concentration of CH31 between 15-22% of the total observed CH31 concentration over the study period. Aggregate-attached bacteria which were estimated to represent about 17% of the total bacteria population were responsible for about 3 7% of the overall bacterial activity. To investigate bacterial-mediated removal of CH31 in estuarine systems, a reliable and reproducible method through adaptations and modifications of existing methods was developed. This method involved the use of [C] radiolabelled CH31 to estimate bacterial utilization of CH31. The application of the method confirmed the removal of CH31 by methylotrophs in estuarine water with the total recorded amount in bacterial cells and oxidized C02 ranging between 9.3 24.5% (depending on the amount of the added substrate). However, this could only represent the potential microbial CH31 removal in the natural aquatic environment. An investigation into spatial and temporal trends in bacterial-mediated removal of CH3I in the Tamar estuary revealed no significant spatial variation but rather a strong seasonality in methylotrophic bacterial CH31 removal. Spatial trends in CH31 removal was found to be mostly influenced by temperature, bacterial abundance and dissolved oxygen concentration whilst the seasonality in the estuary was influenced by temperature, bacterial abundance, suspended particulate matter (SPM) and CH31 concentration. Temperature was identified to be the single most influential physicochemical variable on both spatial and seasonal variation in bacterial CH31 removal in the Tamar estuary. CH31 concentration along the Tamar estuary was also investigated and using this data the total water to air flux of CH31 over the estuary was estimated to be 0.3 I x I 03 g /. From this study, it was apparent that bacteria activity in estuarine systems is potentially an important source of CH 31 in the aquatic environment when associated with aggregates or as sink of CH31 through methylotrophic activity in estuaries.

Corpus-Based Syntactic-Semantic Graph Analysis

This research exemplifies the corpus-based graph approach to the syntactic-semantic analysis of a concept feeling using the Construction Grammar Conceptual network methodology. by constructing a lexical network from grammatically tagged collocations of the english and the Croatian web corpora, the structure of the semantic domains is revealed as a set of sub-graphs derived from the source lexeme’s friend-of-a-friend graph. the subgraph structures, calculated with the community detection algorithm, are interpreted as the semantic domains associated with the source lexeme’s conceptual matrix. lexical structures are analyzed using a centrality algorithm that determines the overall rank of the salience and semantic relatedness to the source concept feeling. this empirical approach can be used for developing nlP methods and tasks, such as computing semantic similarity, sense disambiguation, sense structuring, as well as for comparative corpus and cross-cultural studies.

Intermetallic Compounds in Catalysis

In catalysis, intermetallic compounds play an important role as precursors for skeletal catalysts or can be formed under reaction conditions and influence the catalytic properties significantly. They can also be applied as catalysts in an unsupported state in a large number of reactions. Intermetallic compounds are structurally more complex than elemental metals or substitutional alloys and thus offer a broad range of different crystal and electronic structures. In addition, the often partly covalent bonding in the compounds increases their stability under reaction conditions and enables an innovative realization of geometric and electronic concepts. This article summarizes the work in the field, aiming at presenting the different ideas and not at giving a full literature review. Special emphasis is put on the knowledge-based development, which becomes feasible using unsupported and in situ stable intermetallic compounds as catalysts. Keywords: Heterogeneous catalysis; intermetallic compounds; selective hydrogenation; methanol steam reforming; electrocatalysis; knowledge-based approach; electronic structure; geometric structure
Studies on optical, structural and electrical properties of atomic layer deposited Al-doped ZnO thin films with various Al concentrations and deposition temperatures

We investigated transparent conducting aluminium-doped zinc oxide thin films fabricated by atomic layer deposition (ALD). For the thermal ALD, diethylzinc and trimethylaluminium were used as the Zn and Al precursors, respectively. The electrical, structural and optical properties were systematically investigated as functions of the Al doping contents and deposition temperature. The best resistivity and transmittance (4.2 mΩ cm and ∼85%) were observed at an Al doping concentration of about 2.5 at% at 250 °C. An increase in the carrier concentration was observed with increasing deposition temperature and doping concentration. This can be explained by the effective field model of layered structures. Also, the enhancement of the mobility with increasing doping concentration was studied by the grain-boundary scattering and percolative conduction mechanism. By correlating the electrical and structural properties, it was found that varying the carrier concentration was more effective in changing the mobility than the grain-boundary scattering, due to the hopping conduction.
