Experimental Study of Natural Convection in a Closed Cavity (Static Type Domestic Fridge)

This work provides an analysis of the thermal flow and behavior of the (load-free) refrigerator compartment. The main goal was to compare the thermal behavior inside the refrigerator cavity to the freezer door (home refrigerator) effect and install a fan on the freezer door while neglecting the heat transmitted by thermal radiation. Moreover, the velocity distribution, temperature, and velocity path lines are theoretically studied. This was observed without affecting the shelves inside the cabinet and the egg and butter places on the refrigerator door as they were removed and the aluminum door replaced with a glass door. This study aims to expand our knowledge about the temperature and flow fields of this refrigerator model. Finally, the development of this work highlights the importance of numerical simulation in the search for improvements in the design of this refrigerator model, which may assist refrigerator manufacturers.

WHAT IS BEHIND THE (GLASS)DOOR? EXAMINING TOXIC WORKPLACE CULTURES VIA AN EMPLOYMENT REVIEW SITE

Launched in 2008 as a site to collect the anonymous perspectives of current and former employees as well as their self-reported salaries, Glassdoor.com has grown to be a top destination for American job seekers wanting to learn more about the work environment of particular companies. Using reviewed posted by current and former Riot Games employees (the developer behind League of Legends) as a case study, I argue that Glassdoor is an easily accessible yet underutilized public yet anonymous resource for scholars interested in a peek ‘behind the curtain’ of industries reliant on non-disclosure and non-disparagement agreements, such as the games industry. In this paper I report on my ongoing analysis of 740 current and former employee reviews of Riot posted to Glassdoor between October 2009 and March 2021. Riot is a particularly fruitful case study as it is a company that has been criticized for creating a toxic work environment, with sexual harassment and a lack of promotions for women being frequently discussed in the games media. As a result of this analysis, I argue it provides ample evidence to indicate that Glassdoor can be a fruitful venue for media industry scholars interested in better understanding employee perspectives about 'notorious' companies while mitigating potential harm to informants who might otherwise be reluctant to speak ‘on the record’ about an industry that remains resistant to change.

Improving transparent team communication with the ‘Glass Door’ decal communication tool: a mixed methods analysis of family and staff perspectives

ObjectiveTo determine the value and perspectives of intensive care unit (ICU) healthcare professionals (HCPs) and families about the Glass Door (GD) decal team communication tool.DesignQuality improvement methodology was used to design, test and implement the GD. Uptake was measured through audit. Impact was assessed through mixed methodology (survey of ICU HCPs (n=96) and semi-structured interviews of HCPs (n=10) and families (n=7)).SettingEighteen bed, closed, mixed medical–surgical–cardiac ICU in a tertiary care, university-affiliated, paediatric hospital.PopulationInterdisciplinary ICU HCPs and families of children admitted to the ICU.InterventionA transparent template (the GD) applied to the outside of ICU patients’ doors with sections for HCPs names, physiological goals and planned tests and treatments for the day. Medical staff completed the GD in rounds (AM and PM) and any HCP caring for the patient updated it throughout the day.Measurements and main resultsAfter 3 months, 96% of 613 doors were employed of which 99% respected confidentiality. ICU HCPs reported improved understanding of the patient’s plan (84% today vs 59% pre-GD, p<0.001) and sense that families were up-to-date (79% today vs 46% pre-GD, p<0.001). Based on semi-structured interviews, the GD promoted a shared understanding of the plan contributing to care continuity. The GD reassured families the team is working together and fostered family engagement in the care. Routine family experience surveys showed no change in families’ sense of privacy during admission; families denied the GD’s anticipated compromise of confidentiality.ConclusionsThe GD decal communication tool, visible on the patient’s door, improved ICU HCPs’ perceived knowledge of their patient’s plan. The GD improved the shared mental model, facilitated teaching and information transfer and fostered family engagement. Challenges included knowing the rules for use and consistent application. Concerns initially raised by HCPs about confidentiality were denied by families.

Energy Efficiency Improvement Solutions for Supermarkets by Low-E Glass Door and Digital Semi-Hermetic Compressor

This research presents an energy efficiency improvement solution for supermarkets with the use of low-E glass doors for open refrigerators and a digital semi-hermetic compressor to fix the speed of semi-hermetic compressors. The impact of a door’s installation causes its load to be reduced by 40%, and the compressor shuts down frequently, which decreases its lifetime. In order to ensure that energy-saving solutions do not affect maintenance costs, the installation of a digital semi-hermetic compressor is proposed to lower costs and save energy. Our economic results from tests carried out at a 3000 square meter supermarket, which was open from 6:00 am to 12:00 am and in which we installed 82 doors on 15 open refrigerators, showed a 1.1-year payback period with an energy saving rate of 192,220 kWh/year for store No.1 (R22) and in which we installed 80 doors on 15 open refrigerators, showed a 1.4-year payback period with an energy saving rate of 171,185 kWh/year for store No.2 (R404A). The energy-saving effects of the digital semi-hermetic compressor, which fixes the speed of the semi-compressor and solves the problem of impact from fridge door installation, showed a 2.9-year payback period with an energy saving rate of 26,890 kWh/year for store No.1 (R22) and showed a 2.9-year payback period with an energy saving rate of 26,571 kWh/year for store No.2 (R404A). The results of store No.1 (R22) and store No.2 (R404A) showed no differences. This research is an extension of an energy-saving project that can be carried out on a continuous basis, increasing the efficiency of energy use and being a sustainable source of energy conservation.

“Goodbye … Through a Glass Door”: Emotional Experiences of Working in COVID-19 Acute Care Hospital Environments

Background The severity of the COVID-19 health crisis has placed acute care nurses in dire work environments in which they have had to deal with uncertainty, loss, and death on a constant basis. It is necessary to gain a better understanding of nurses’ experiences to develop interventions supportive of their emotional well-being. Purpose The purpose of this study is to explore how nurses are emotionally affected working in COVID-19 acute care hospital environments. The research question is: What is the emotional experience of nurses working in COVID-19 acute care hospital environments? Methods We employed a narrative methodology that focused on participants’ stories. Twenty registered nurses, who worked in six hospitals in the Greater Toronto Area in Canada, participated in interviews. A narrative analysis was conducted with a focus on content and form of stories. Results We identified three themes about working in COVID-19 acute care hospital environments: the emotional experience, the agency of emotions, and how emotions shape nursing and practice. Conclusion In moving forth with pandemic preparations, healthcare leaders and governments need to make sure that a nurse’s sacrifice is not all-encompassing. Supporting nurses’ emotional well-being and resilience is necessary to counterbalance the loss and trauma nurses go through.

Designing a shaped balloon machine with a waterwheel mechanism

This paper explores the mechanism design of a balloon machine representing a vending machine where consumers can select their desired shapes, as well as avoid bursting caused by manual inflation. Inside the machine, balloons are placed on the mechanism designed based on a waterwheel which rotates at a constant speed generated by motion among different sizes of gears. When rotating to the corresponding shaped balloon, the inflator will move under the opening to pull it out from the display point and start to inflate the balloon for the set number of seconds. After the inflation is completed, the glass door will open and the customer can take out their balloon. The main purpose of our development and design of the balloon machine is to improve the general balloon blowing and it is easy to prevent over-exposure and blast. The balloon machine can automatically inflate and detect the blowing time to improve the shortcomings of the balloon’s blast. In this way, it can effectively decrease sudden explosions and the number of frightened people.

Self-employment and wage difference an analysis for Brazil

PurposeThe aim of this study is to evaluate the wage gap between men and women who seek self-employment in Brazil, whether because they want to become entrepreneurs out of necessity or because of the flexible hours.Design/methodology/approachThe data used are from the 2015 National Household Sample Survey (PNAD) and the methods are the ordinary least squares (OLS) for the Mean and the unconditional quantile regression (RIF-regression) for the distribution of gains of both genders, both associated with the Oaxaca–Ransom decomposition in order to separate the differential between the part explained by attributes and the unexplained part.FindingsThe main results show that women earn less than men in the mean and throughout the distribution. The average difference is 27.79%, varying between 19.24 and 48.26% in the distribution. The inclusion of occupational variables shows that the glass door phenomenon exists even in self-employment, that is, women choose occupations with lower incomes.Originality/valueStimulating self-employment has been an alternative policy for the insertion of women in the labor market. This is the first study on the wage gap in self-employment in the Brazilian labor market. The presence of wage differentials among self-employed men and women throughout the distribution may point to the need for specific policies that not only target the mean. These policies would be related to sticky floor and to the glass ceiling. Another potential problem concerns the so-called glass door–women access the labor market via professions that pay less, otherwise, the problem points to occupational segregation against women.Peer ReviewThe peer review history for this article is available at: https://publons.com/publon/10.1108/IJSE-05-2019-0312

Analysis of the Thermal Behavior of an Earthbag Building in Mediterranean Continental Climate: Monitoring and Simulation

Nearly 30% of humanity lives in earthen dwellings. Earthbag is a sustainable, cheap, feasible and comfortable option for emergency housing. A comparative monitoring-simulation analysis of the hygrothermal behavior of an Earthbag dwelling in Mediterranean continental climate, designed under bioclimatic criteria, is presented. The dome shape Earthbag dwelling has a net floor area of 7.07 m2, a glass door facing south and two confronted windows in the east and west facades. A numerical model (EnergyPlus v8.8) was designed for comparison. Twenty-four hour cross ventilation, night cross ventilation, and no ventilation in free floating mode and a controlled indoor temperature were the tested scenarios. Comparisons between experimental data and simulation show a good match in temperature behavior for the scenarios studied. Reductions of 90% in summer and 88% in winter, in the interior thermal amplitude with respect to exterior temperatures are found. Position of the glazed openings was fundamental in the direct solar gains, contributing to the increase of temperature in 1.31 °C in winter and 1.37 °C in the equinox. Night ventilation in the summer period had a good performance as a passive system. Passive solar gains made a reduction of heating energy consumption of 2.3% in winter and 8.9% in equinox.

Fiction as Information

Information Literacy is built on the idea that when we encounter information we can evaluate that information to incorporate into our knowledge schema. As such information can be encountered in a variety of ways, as academic information, workplace information, or everyday life information. Art forms can also be considered information, including literature. As an art form literature has been theorized to be a window, mirror, and a sliding glass door (Bishop, 1990) to the reader, an information source regarding our world. The notion that fiction is an information source is not particularly considered in much of the information literacy scholarly research. This paper examines how adolescents engage with fiction as a source of information. Using a small case study of a class of 16 and 17 year olds the paper examines how they construct ficiton and aesthetic reading as an information source, particularly using the metaphor of the window and the mirror. While students might consider reading as a way to explore their identity, elements related to their stance towards reading impacted their ability to see reading fiction as an information source. Furthermore they were unlikely to engage fiction as a "window" or a way to learn about others. Specific pedagogical structures may encourage a more critical stance towards aesthetic reading as a way to engage in as a learning object.

Ml based Naive Bayes Methodology for Rate Prediction Using Textual Rating and Find Actual or Movie Rating based on Mbnbr Optimization

We've experienced a bulk of review pages such as Amazon, Flip Kart & Facebook, book my show and some applications etc., in latest studies. It offers an excellent chance to share our reviews for different goods we buy. However, we are faced with the issue of duplicating data. It is essential where to stock precious data from feedback to comprehend the desires of a user and create a precise suggestion. Some variables, such as user buy documents, item type, and geographic place, are considered by conventional recommendation schemes. We suggest a Feeling Forecast Technique (FFT) in this job to enhance forecast precision in recommendation schemes. First, we suggest a personal assessment strategy for personal consumers and determine the feeling about objects/products of each customer. Second, we regard not only the own emotional characteristics of a customer but also the relational emotional impact. After which they count the credibility of the item that could be deduced from a consumer sets emotional scores reflecting the extensive assessment of clients. Finally, we combine in our recommendation scheme three elements feeling resemblance relational emotional, impact, and notoriety resemblance of item to create a precise forecast of rating. On an actual-world sample obtained from Glass door, we undertake a quality assessment of the three emotional variables. Our findings show that the feeling can well describe display settings that help improve the effectiveness of recommendations. Above all discussion is analyzed with ML based Naive Bayes optimization got 20% more efficiency compared to existed methods like linear regression, etc
