Bridges across languages and cultures: Narratives of long-term English learners

ABSTRACT This narrative inquiry highlights the experiences of three high school students labeled Long-term English learners (LTEL) in a North Texas high school. This narrative inquiry study uses semi-structured interviews to restory the students’ lives, emphasizing the emergent themes of family (the strongest pillar) and the language of the home (Spanish). The metaphor of the bridge, a connector across language and culture, offers insights into the students’ perspectives of their developing identities as bilingual and bicultural youth. Regarding the theme family (the strongest pillar), the students perceived their families as connecting them to their cultural heritage, providing emotional/social bonds, and advancing their academic interests. Regarding the theme the language of the home (Spanish), the students valued Spanish as the language of the heart, interlinking them with their native roots. Moreover, the students’ narratives demonstrate the importance of integrating additive learning experiences at school, designed to support LTEL students’ native languages and cultures. The article concludes with a pragmatic discussion about cultivating inclusive schooling cultures for LTEL learners.
Effect of Nanocomposite Clay/low-density Polyethylene Film on the Quality of Rainbow Trout (Oncorhynchus mykiss) Fillets Stored with Four Different Packaging Conditions

ABSTRACT To improve the quality and increase the shelf life of rainbow trout fillets, nanocomposite clay/low-density polyethylene films were used during 25 days of refrigerated storage (4 °C). Low-density polyethylene (LDPE) films with 5 wt% clay nanoparticles (sodium montmorillonite, MMT) were used for packaging of rainbow trout fillets using 4 different packaging conditions (modified atmosphere packaging (MAP): 60 N2, 35 CO2, and 5% O2; vacuum packaging (VP); air packaging (AP); and control). Fish samples were analyzed on the first day and every 5 days to determine the extent of microbial deterioration, chemical changes, and sensory properties. Based on obtained results, the shelf life of rainbow trout fillets was determined as ~10 days for the control group, and 15, 20, and 25 days for the AP, VP, and MAP packages, respectively.
Challenges in modelling the unsteady aerodynamics of wind turbines

Many of the aerodynamic phenomena contributing to the observed effects on wind turbines are now known, but the details of the flow are still poorly understood and are challenging to predict accurately. This article emphasizes two key areas that need continued serious consideration for wind turbine predictive analyses: the modelling of the rotor wake and the modelling of the unsteady aerodynamics of the blade sections. Issues discussed herein include the modelling of the induced velocity field produced by the vortical wake behind the turbine, the various unsteady aerodynamic issues associated with the blade sections, and the non-linear intricacies of dynamic stall. Fundamental limits exist in the capabilities of all models, and ambiguities can also arise in how these models should be properly applied. A challenge for analysts of the future is to use complementary experimental measurements and modelling techniques to better understand the aerodynamic problems found on wind turbines, and to develop more rigorous models with wider ranges of application.

Consistent development of bioprocesses from microliter cultures to the industrial scale

Bioprocess development today is slow and expensive compared to chemical process development. A drastic paradigm shift is necessary and possible by the consistent application of engineering strategies that are typically used in the process development phase already in the early product development. Aside from providing a consistent pathway, strategies such as statistical‐based design of experiments, fed‐batch, minibioreactors, new on‐line sensors, process modeling, and control tools in combination with automation of manual steps offer a higher success rate and the opportunity to find the optimum parameters and operation point. This also directly benefits the early phases of biomolecular screening and initial production of small amounts of the target molecule. The paper reviews the bioprocess developmental phases from a business perspective and the available systems and technologies.
Fabrication of Precise Fluidic Structures in LTCC

A number of emerging applications of low-temperature co-fired ceramic (LTCC) require embedded fluidic structure within the co-fired ceramic and or precise external dimensional tolerances. These structures enable the control of fluids for cooling, sensing, and biomedical applications, and variations in their geometry from the design can have a significant impact on the overall performance of the devices. One example of this type of application is a multilayer cooler developed recently by the authors for cooling laser diode bars. In many laser systems, laser diodes are the primary emitters, or assemblies of these diode bars are used to pump traditional laser crystals such as Nd:YLF. Assemblies of these diodes require large amounts of electrical current for proper operation, and the device operating temperature must be carefully controlled in order to avoid a shift in the output wavelength. These diodes are packaged into water-cooled assemblies and by their nature dissipate enormous amounts of heat, with waste heat fluxes on the order of 2000 W/cm2. The traditional solution to this problem has been the development of copper multilayer coolers. Assemblies of laser diodes are then formed by stacking these diode bars and coolers. Several problems exist with this approach including the erosion of the copper coolers by the coolant, a requirement for the use of deionized water within the system, and a significant CTE mismatch between the diode bar and the metal cooler. Diodes are bonded to these metal structures and liquid coolant is circulated through the metal layers in order to cool the diode bar. In contrast, the coolers developed by the authors utilize fluid channels and jets formed within LTCC as well as embedded cavity structures to control the flow of a high-velocity liquid and actively cool the laser diode bars mounted on the surface of the LTCC. † The dimensional tolerances of these cooler assemblies and complex shapes that are used to control the fluid can have a significant impact on the overall performance of the laser system. This paper describes the fabrication process used to create the precise channel and jet structures used in these LTCC-based coolers, as well as some of the challenges associated with these processes.
Ablative Procedures and Additional Anticancer Therapy Prolong the Survival in Patients With Endoluminal or Mixed-type Malignant Central Airway Obstruction: A Single-institution Retrospective Study

BackgroundIn patients with malignant central airway obstruction (MCAO) receiving transbronchial interventions (TBIs), it remains unclear if the prognosis after the intervention might differ according to the bronchoscopic appearance of the airway obstruction. MethodsTBIs were undertaken in MCAO patients with endoluminal obstruction (TM group, n = 19), extraluminal obstruction (EX group, n = 19) and mixed-type obstruction (MX group, n = 23), under moderate sedation and high fractions of inspired oxygen (FiO2). We evaluated the differences in the overall survival period (OS) after the TBIs among the 3 groups. ResultsRegarding the TBIs, the initial procedure was transbronchial microwave ablation (TMA) in the TM group and MX group and stent placement in the EX group. However, 7 patients in the MX group received stent placement as the second-line procedure, after failure of TMA. The OS tended to be longer in the TM/MX group as compared to that in the EX group, both in the subgroups of patients who received post-TBI anticancer therapy (27.2 months/32.9 months vs. 6.0 months, p = 0.011) and in the subgroups of patients who received best supportive care alone (3.2 months/3.1 months vs. 1.4 months, p = 0.072). Multivariate analysis identified adoption of TMA as the initial procedure, successful airway patency restoration following the TBI, and post-TBI anticancer therapy as independent factors associated with a reduced risk of death in patients with MCAO. ConclusionIt is beneficial to administer post-TBI anticancer therapy to MCAO patients with endoluminal or mixed-type obstruction following ablative procedures.
Analysis of a Two-Body Floating Wave Energy Converter With Particular Focus on the Effects of Power Take Off and Mooring Systems on Energy Capture

The present paper summarizes analyses of a two-body floating wave energy converter (WEC) including the mooring system. An axi-symmetric Wavebob type WEC is chosen as the object of investigation here. However, the PTO system is modeled in a simplified manner as ideal linear damping and spring terms that couples the body 1 and the body 2 motions. The analysis is done using SIMO, a time domain simulation tool which accommodates simulation of multi-body systems with hydrodynamic interactions. In SIMO, docking cone features have been introduced between the two bodies to let them move as per actual operation and fenders are applied to represent end stops. Six alternative mooring configurations are applied to investigate the effect of mooring on power capture. In this paper, the software HydroD using WAMIT for hydrodynamic is used to determine hydrodynamic loads. The analysis is carried out for several regular and irregular wave conditions as representative of operational conditions. Simulations are performed with the purpose to study the effects of power take off (PTO) system, end stops setting and several mooring configurations on power captured by the WEC.Copyright © 2011 by ASME

Economic growth, renewable energy consumption, and ecological footprint: Exploring the role of environmental regulations and democracy in sustainable development

Countries enact environmental regulations to achieve sustainable development andecological sustainability. However, environmental regulations do not guarantee envi-ronmental sustainability unless implemented efficiently. Furthermore, political institu-tions play a key role in the formulation and management of environmentalregulations. This research examines the relationship between democracy, environ-mental regulations, economic growth, and ecological footprint (EF) in the panel of G7nations from 1985 to 2017. Second generation econometric techniques are used toanalyze the data. The empirical evidence indicates that economic growth enhancesEF while democracy and environmental regulations positively contribute to ecologicalsustainability by reducing EF. The causal outcomes reveal that democracy Grangercauses EF and renewable energy indicating that democracy curbs environmental deg-radation and stimulates the share of renewables. Further, democracy and environ-mental regulations Granger cause each other. Lastly, the implication of these findingsfor sustainable development and ecological sustainability are discussed.
Quality assessment of an Ultra-Wide Band positioning system for indoor wheelchair court sports

Ultra-Wide Band radio positioning systems are maturing very quickly and now represent a good candidate for indoor positioning. The aim of this study was to undertake a quality assessment on the use of a commercial Ultra-Wide Band positioning system for the tracking of athletes during indoor wheelchair court sports. Several aspects have been investigated including system set-up, calibration, sensor positioning, determination of sport performance indicators and quality assessment of the output. With a simple set-up procedure, it has been demonstrated that athletes tracking can be achieved with an average horizontal positioning error of 0.37 m (σ = ± 0.24 m). The distance covered can be computed after data processing with an error below 0.5% of the course length. It has also been demonstrated that the tag update rate and the number of wheelchairs on the court do not affect significantly the positioning quality; however, for highly dynamic movement tracking, higher rates are recommended for a finer dynamic recording.
Differences in Self-Rated Health and Physical Activity due to Education Level among Koreans: Understanding Implications of Physical Education

Background: We aimed to explore the effect of education levels on self-rated health and physical activity (PA) and to provide basic data for developing interventions based on physical education to improve the quality of life among Koreans. Methods: The 2019 Community Health Survey data were selected through primary and secondary phylogenetic extraction. The survey was conducted among Korean adults aged ≥19 years (n=229,099), in 2019, using an electronic questionnaire. The education levels were classified into eight groups: uneducated, Seodang/Hanhak (traditional Korean school), elementary school, middle school, high school, college (2 or 3 years), university (4 years), and post-graduate or higher. In this study, the effect of participants’ education levels on self-rated health levels and PA was investigated (the PA subdimensions were: the number of days of vigorous PA, moderate-intensity PA, walking, and flexibility exercises). Results: 1) Regarding self-rated health, significant differences according to education level were recorded (P<0.001), with higher education levels leading to higher averages. 2) Regarding PA, significant differences according to education level were revealed, and the number of days of vigorous PA, walking, and flexibility exercise (P<0.001) increased with higher education levels. Moreover, the university (4 years) group reported the highest average. However, the middle school group reported the highest average for the number of days of moderate-intensity PA (P<0.001), and the average number of days decreased as the education level increased after middle school. Conclusion: Education plays an important role in maintaining health, and practicing appropriate PA contributes to one’s quality of life.
EXAMINING THE IMPACT OF HABIT, WORKLOAD, AND WORK ENVIRONMENT TO WORK STRESS ON MILLENNIAL GENERATIONS

Gender, Age and Staff Preparedness to Adopt Internet Tools for Research Sharing During Covid-19 in African Varsities

This study assessed the partial as well as the collaborative impact of age and gender on academic staff preparedness to adopt Internet tools for research sharing in African universities during Covid-19. Although evidence abounds in the literature on gender and age as they affect relatively, scholars’ utilisation of digital tools for research communication, such studies did not examine scholars’ preparedness to adopt from a broad perspective of Africa. This study was conducted based on the argument that the preparedness of scholars may affect their future interest to utilize digital tools for research sharing. A quantitative method, based on the descriptive survey research design, was adopted to provide answers to four prevailing research questions. The examination focused on a populace of 8,591 staff in African universities, nonetheless, information was gathered from 1,977 of them, who deliberately took part from 24 African nations. A validated electronic rating scale, which was mailed/posted to targeted participants, was used as the instrument for data collection. Gender and age significantly affected academic staff preparedness to adopt Internet tools for research sharing partially and interactively in African Universities during Covid-19. Female staff were more prepared than males to adopt internet tools for research sharing during the pandemic. Older lecturers reported a higher rate of preparedness than their younger colleagues to adopt Internet tools for research sharing during Covid-19. In light of these proofs, ramifications and proposals for future exploration are discussed.
Meeting the Burden of Proof with Case-Study Research

The case-study research method is popular across various disciplines; however, critics of the method argue that results from this form of research are applicable only to the case studied and cannot be generalized further. In the field of construction engineering and management (CEM), the number of papers employing case-study research methods over the past decade has increased substantially. As the method proliferates, the question arises: are CEM case studies being performed with sufficient validity and reliability to meet the burden of proof to generalize from the case-study findings? Meeting the burden of proof is particularly critical in CEM because of the unique, site-based nature of the projects and industry. This paper presents a review of 156 papers employing case studies published in the Journal of Construction Engineering and Management, of which the writers identified 33 theory-building case-study-method papers. This subset of theory-building papers was examined to induce a set of requirements a.
Offering soybean molasses adsorbed to agricultural by‐products improved lactation performance through modulating plasma metabolic enzyme pool of lactating cows

Abstract Background Agricultural by‐products, such as corncob powder (CRP), wheat bran (WB), rice husk (RH), defatted bran (DB), and soybean hulls (SH), were widely used as ruminant feed. However, the combination effect of soybean molasses mixed with agricultural by‐products on cow lactating performance remains poorly understood. Methods In vitro fermentation simulation technique was used to select the high ruminal fermentation performance of agricultural by‐products mixed with soybean molasses. The selected mixtures were conducted to further explore the feeding effect on milk performance and blood metabolic enzyme on lactating dairy cows. Results In in vitro simulation, it was confirmed that SH‐SM showed better fermentation performance (including higher maximum gas production, acetate, propionate, and total VFA, but less initial fractional rate of degradation) than other four molasses‐adsorbents, while WB‐SM had the greatest DM and NDF disappearance and NH3‐N and butyrate concentrations among substrates. After the simulation selection, we performed the feed experiment with SH‐SM and WB‐SM compared to the control. For lactating performance, higher (p < .01) milk fat and total milk solid content were observed in WB‐SM, and a tendency improvement of milk protein content (p < .01) was observed in both of the cows fed with WB‐SM and SH‐SM. Among lactating periods, the blood glutamic‐pyruvic transaminase, α‐amylase, and lactate dehydrogenase which associated with amino acid metabolism and carbohydrate metabolism were improved in lactating dairy cows fed with WB‐SM and SH‐SM. Conclusion Dietary agricultural by‐products (like wheat bran and soybean hulls) mixed with soybean molasses enhance the lactating performance of dairy cows by improving the host metabolism process of amino acids and carbohydrates. The mixed strategy for agricultural by‐products shows another strong evidence for the resource reuse on dairy industry and reducing the by‐product pollution.
Numerical analysis of heating transient of electric contacts under short-circuit conditions

A model for the simulation of the heating transient of contact elements under short-circuit conditions is described. The model permits the determination of the maximum temperature reached by the contact area under defined test conditions. In such a way it is possible to identify the conditions which do not cause contact welding. Numerical results obtained by simulation have been compared to the results of an experimental investigation on normal production contacts. >
Waveform Compensation of PWM Inverter with Cyclic Fluctuating Loads

This paper describes a new repetitive voltage compensation technique which generates high quality sinusoidal output voltage from a single-phase PWM inverter used for uninterruptible power supplies (UPS). A repetitive control technique eliminates the steady-state error in the distorted output voltage caused by cyclic loads such as rectifier and triac loads. The proposed PWM inverter system employs a microprocessor based closed loop digital feedback with a sinusoidal reference. The PWM pattern is determined at every sampling instant by the proposed new algorithm implemented by a microprocessor using a set of detected output voltages and the reference signals through one cycle. The system has low distortion and very fast response for ac phase controlled loads.
