Visualization of left common carotid artery injury by glass using postmortem virtual angioscopy.

A deceased man in his 50s was found with his neck over a broken glass door frame, with blood around the body. A non-contrast postmortem computed tomography (PMCT) scan revealed subcutaneous hemorrhage, temporal bone fracture, and cerebral contusion. Also, wounds extending from the anterior to posterior neck and the presence of air in the cervical vessels suggested cervical vascular injury. A virtual angioscopy image reconstructed from PMCT angiography data revealed a ruptured left common carotid artery and allowed accurate measurement of the injury. This case demonstrates the effectiveness of postmortem virtual angioscopy for visualization and evaluation of vascular injuries, providing valuable insights for forensic investigation.

Human Scream Detection and Analysis for Controlling Crime Rate using Machine Learning and Deep Learning

Abstract: This paper addresses the problem of automatic detection and recognition of impulsive sounds, such as glass breaks, human screams, gunshots, explosions or door slams. A complete detection and recognition system is described and evaluated on a sound database containing more than 800 signals distributed among six different classes. Emphasis is set on robust techniques, allowing the use of this system in a noisy environment. The detection algorithm, based on a median filter, features a highly ro- bust performance even under important background noise conditions. In the recognition stage, two statistical classifiers are compared, using Gaussian Mixture Models (GMM) and Hidden Markov Models (HMM), respec- tively. It can be shown that a rather good recognition rate (98% at 70dB and above 80% for 0dB signal-to-noise ratios) can be reached, even under severe gaussian white noise degradations.

Transparent, superhydrophobic, and flexible polyimide films with robust and durable imide/silica particles surface prepared via a sintering process

Recently, transparent superhydrophobic surfaces have attracted great interest due to their potential applications in various fields, such as skyscrapers, windows, glass doors, displays, and solar panels. However, flexible films with superhydrophobicity and transparency still face challenges in practical applications due to their lack of durability of the properties. Here, we report transparent, superhydrophobic, and flexible polyimide films with robust oligoimide/silica protrusion surface prepared by a simple sintering process, aiming to address the above issues. A transparent polyimide film (PIF) and nano-silica particles modified with an oligoimide (NSOI) were separately prepared, and the sintering between PIF and NSOI were performed to obtain PINSOI samples. Among PINSOIs, the optimal PINSOI-3 sample exhibited excellent superhydrophobicity, optical transmittance and tensile strength. After folding/torsion, sandpaper abrasion, tape peeling and acidic/basic immersion tests, its superhydrophobicity was maintained, indicating excellent mechanical and chemical durability of superhydrophobicity even under harsh conditions. Also, after a standard accelerated weathering test, its superhydrophobicity, transmittance and tensile strength were almost completely maintained, indicating the excellent weathering durability of PINSOI-3. These durability properties of PINSOI-3 could be attributed to that the sintering resulted in strong fusion between the NSOI particles and PIF by chain entanglement. PINSOI-3 showed excellent self-cleaning performance, and it can be applied as a self-cleaning film for flexible or curved solar cells and displays.

Experimental and theoretical exploration of terahertz channel performance through glass doors

In the evolving landscape of terahertz communication, the behavior of channels within indoor environments, particularly through glass doors, has garnered significant attention. This paper comprehensively investigates terahertz channel performance under such conditions, employing a measurement setup operational between 113 and 170 GHz. Analyzing scenarios frequently induced by human activity and environmental factors, like door movements, we established a comprehensive theoretical model. This model seamlessly integrates transmission, reflection, absorption, and diffraction mechanisms, leveraging the Fresnel formula, multi-layer transmission paradigm, and knife-edge diffraction theory. Our experimental results and theoretical predictions harmoniously align, revealing intricate dependencies, such as increased power loss at higher frequencies and larger incident angles. Furthermore, door interactions, whether opening or oscillations, significantly impact the terahertz channel. Notably, door edges lead to a power blockage surpassing the transmission loss of the glass itself but remaining inferior to metallic handle interferences. This paper's insights are pivotal for the design and fabrication of terahertz communication systems within indoor settings, pushing the boundaries of efficient and reliable communication.

BIM-based environmental assessment of residential renovation projects during the operational phase

ABSTRACT Reducing energy consumption and greenhouse gas emissions to combat global climate change has become an international necessity. A large portion of energy consumption is attributed to old buildings, with increased operational costs and decreased occupational comfort. These buildings require renovation measures that can be viewed as an opportunity to implement sustainable construction and create traditionally designed buildings based on sustainable construction. This study proposes a combination of building information modeling (BIM) with Design Builder and Meteonorm software to evaluate the environmental impact of renovating buildings during the operational phase. The process involved is demonstrated in a case study application to a typical two-story single-family residential building in Tehran city, in which the building’s materials, weight, and volume are determined using Revit software, and Design Builder is used to simulate the renovation effect on various building components – showing that, by combining the most effective insulation, glass, heating system, and doors, a 15% reduction in energy consumption and 44% reduction in CO2 emissions could be achieved. The study significantly advances knowledge in sustainable building practices by introducing a practical framework for decision-making in environmentally conscious building renovations, focusing on such crucial elements as insulation materials, window glass types, heating systems, and door materials. It also provides valuable insights into the practical implications of weather data for accurate environmental forecasting, emphasizing the methodology's applicability and adaptability to similar contexts, as evidenced by its successful application in a real-world case in Tehran.

PT. Tjakrindo Mas is a manufacturing company based in Indonesia that supports the government, industrial, public, and private sectors. Established in 1984, the company produces home furniture made from various types of wood. During the period from December 2023 to May 2024, the company faced production issues with its furniture products. According to production scheduling data, the furniture production intensity was high, operating 5 days a week. During this period, the highest production rate was for the 2 Door Glass Wardrobe, totaling 5,638 units. However, despite the high production volume, the defect rate for the 2 Door Glass Wardrobe was also high, with 498 defective units, representing a defect rate of 8.83%, which exceeds the company's tolerance standard. The objective of this study is to assess the quality of the Glass Wardrobe product at PT. Tjakrindo Mas and to propose improvements to enhance the product quality. Observations identified that the highest Risk Priority Number (RPN) was associated with the close side rail rupture defect, caused by the operator not being careful when installing the close side rail to the cabinet body, and the work methods used not in accordance with the Standard Operating Procedure (SOP). Recommendations for quality control proposals based on the high RPN value of FMEA Close Side Rail Rupture is to provide supervision and guidance to workers, and Provide briefing to operators about methods that are in accordance with the standard operating procedures (SOP) used by the company.

On the Center: Mirror-Window- Sliding Glass Door Books in the Middle East Picture Book Award

Children’s literature can serve as mirrors, windows, and sliding glass doors. They are mirrors for marginalized groups to see themselves represented, windows for dominant cultures to learn about marginalized groups, and sliding glass doors to develop empathy. In this study, I examined Middle East Picture Book Award to address what books are available about Middle Eastern Muslims who experience xenophobia and Islamophobia; and identify the books that serve as mirrors-windows-sliding glass doors.

Switchable and optically transparent ultrawide stopband frequency selective surface for electromagnetic shielding

In view of the fact that high-frequency electromagnetic waves mainly enter buildings through windows and glass doors, switchable optically-transparent shielding with broad stopband is increasingly needed. Herein, a novel design for a switchable and optically transparent frequency selective surface (FSS) with ultrawide-stopband is presented in this study. The structure consists of a polymethyl methacrylate (PMMA) layer sandwiched between polydimethylsiloxane (PDMS) layers which contain liquid metal microchannels arranged in an orthogonal Ω-shaped configuration. The mobility of the liquid metal can switch the FSS response from an all-pass to an ultrawide bandstop behavior. The proposed FSS achieves a rejection bandwidth of 18.1 GHz, covering P, L, S, C, X and Ku bands, while maintaining a transparency of 81% and high angular stability up to 80°, regardless of polarization. Furthermore, the mechanism behind the ultrawide stopband and high angular stability is explored through an analysis of reflection and absorption for both TE polarization and TM polarization. Experimental validation under both normal and oblique incidence demonstrates the ultrawide-stopband performance of the fabricated FSS.

Perancangan dan Pembuatan Sistem Power Window pada Mobil Daihatsu Zebra Tahun 1995

Power window system is a series of electrical body system that functions to facilitate the driver when opening and closing the glass door electrically by using a power window switch mounted on the inside side of the door, where the manual power window system driver must rotate the glass opening lever to raise and lower the door glass. The power window motor rotates when the power window switch is pressed. The power window motor rotation will turn up and down through the door glass regulator to open or close the door glass.
 The power window application process includes preparation of component placement design and preparation of materials to be used such as motor power windows, relays, fuses and switches, after all is ready, then the installation of components such as motor power windows to the regulator which has been modified in the form of additional plates for the holder The motor, after the power window regulator is ready, then assembles the electrical system and the installation of connections or sockets to each component. After the regulator and the electrical system are ready then install the switch holder on the door trim that has been prepared.
 The results of the power window application obtained power window can work in accordance with its function using a switch, namely the glass door can move up and down according to the position of the switch button pressed on each switch and from the results of the measurement process that the average voltage requirement for the power window to the position goes up 11.5 V while the position goes down 12V. The average time needed to raise the glass on the door 3.63 seconds and to lower the glass door takes 2.78 seconds

Detection and Measurement of Opening and Closing Automatic Sliding Glass Doors

This paper proposes a method for the recognition of the opened/closed states of automatic sliding glass doors to allow for automatic robot-controlled movement from outdoors to indoors and vice versa by a robot. The proposed method uses an RGB-D camera as a sensor for extraction of the automatic sliding glass doors region and image recognition to determine whether the door is opened or closed. The RGB-D camera measures the distance between the opened or moving door frames, thereby facilitating outdoor to indoor movement and vice versa. Several automatic sliding glass doors under different experimental conditions are experimentally investigated to demonstrate the effectiveness of the proposed method.

A discursive presentation of community pharmacies: Premises, storage, staff, documentation and legal compliance

ObjectivesThis study aimed to assess compliance with legal requirements, safe medication storage and staffing standards in community pharmacies in Punjab, Pakistan. MethodWe conducted a three-step cross-sectional study using observations, questionnaires and face-to-face interviews in 544 systematically-selected community pharmacies. We used descriptive statistic and one-way ANOVA to assess the data. ResultsOnly 23 (4.2 %) pharmacies had accurate area and only 3.9 % had appropriate walls. In total, 23.3 % had glass-fronted shelves and 38.2 % had a glass door. More than half (53.8 %) had separate narcotics shelves and 43.0 % a separate shelf of expired medicines. Less than half (47.5 %) of the pharmacies were able to maintain hygiene. About 36.2 % of the pharmacies segregated different types of product. Drugs were protected from direct sunlight in most (61.3 %) pharmacies, but the refrigerator was working properly in less than half (43.4 %) and only a very small number (2.4 %) had an alternative power supply for the refrigerator. Only 37 (6.8 %) were able to maintain an appropriate room temperature. The vast majority (93.0 %) displayed a valid drug sale license, but a qualified person/pharmacist was only present in 4.8 %. The average number of employees was 4.2, and more than 71.0 % of staff had 10–12 years of formal education. Only 0.2 % of employees could explain term “PRN”, although 57.3 % explained “IV” correctly. About 22.8 % replied correctly about the room temperature but the vast majority (97.6 %) did not know about cold chain temperature. The location of the pharmacy (p-value = 0.045) affected its performance. ConclusionsNoncompliance with legal requirements, unsafe drug storage and limited human resources reflect the poor enforcement of drug laws in Pakistan. The findings suggest that there is a need to strengthen inspection and management of community pharmacies.

Active vibration control for window rattling caused by infrasound: Field experiment for one pair of sliding glass doors installed on the test building

We developed an active vibration control system to reduce window vibration caused by infrasound since serious environmental noise problems such as window rattling have remained in Japan. In our previous study, we demonstrated the application of active noise control for the window vibration to reduce the transmitted sound into the room by using the low-frequency sound generator as the secondary source. However, active noise control using sound waves has the problem of increasing the sound pressure level in some areas outside the control window. Therefore, we developed an active vibration control system equipped with self-made inertial vibration exciters and laser displacement gauges to reduce the window vibration caused by infrasound without increasing the sound pressure level. An experiment was conducted to investigate the applicability of the developed active vibration control system to reduce window vibration. The vibration of one pair of sliding glass doors installed in the test building was controlled by the developed systems mounted on windows so that vibration displacement became static. As a result, the displacement of window vibration caused by infrasound was reduced by one-third without increasing the sound pressure level outside the test building. This vibration reduction resulted in the transmitted sound into the room by up to 11 dB within the frequency range below 16Hz.

Peopling Technologies educational model

This conceptual paper articulates a digital education approach that privileges diverse learners and harnesses the potential of technologies. The approach positions digital ways of thinking in terms of a philosophy (Peopling Technologies), a pedagogy (Immediate, Collaborative, Interactive pedagogy) and an evaluative framework (Sliding Glass Doors Learning). The three elements in concert focus closely on, and are responsive to, student contexts and skills. This balance forms an overall Peopling Technologies educational model designed to support students through transition to university and ongoing engagement in their studies. This educational model has practical implementation in the context of curriculum design and assessment design. The approach was developed in 2019, with ongoing iteration taking place in an education course assessment redesign project. Digital learning environments, shaped by this model, encourages belonging and inclusion to cultivate digital literacies, academic skills, discipline knowledges, and professional practice. The Peopling Technologies education model is adaptive to different discipline areas and elements of the approach are iterative to further contexts. By virtue of this model’s philosophical and pedagogical elements, this approach can be flexibly applied to changing contexts and responsive to technological advances (for example, generative artificial intelligence).

Lethal threat in the use of glass doors at home: A case report

BackgroundVarious instruments, including glass fragments, can inflict sharp-force damage, resulting in injuries ranging from superficial wounds to life-threatening trauma. This case report explores the lethal consequences of a 78-year-old man accidentally sustaining a stabbed-incised wound after falling against an ordinary glass door, leading to fatal bleeding from the subclavian artery. Case Report:The man's fall caused a sharp-edged glass fragment to penetrate his neck, resulting in a fatal outcome despite resuscitation attempts. Autopsy Findings:The autopsy revealed a transected subclavian artery, additional injuries to the thorax. Notably, the type of glass used in construction played a crucial role in the severity of injuries, emphasizing the need for safety standards and awareness in architectural design. DiscussionThe discussion delves into the historical use of annealed glass in construction and the evolution of safety standards for architectural glazing materials. A comparison between annealed and tempered glass underscores the importance of the latter in preventing severe injuries. The prevalence of annealed glass in older constructions raises concerns, given its propensity to cause larger and more dangerous shards upon breakage. The report highlights cases of glass-related fatalities, emphasizing the unexpected dangers associated with glass-topped furniture. ConclusionsRecommendations include the adoption of safety glass in new constructions, particularly in residences with elderly occupants, and the installation of night lights to mitigate the risk of injuries from glass and other furniture. The report contributes to enhancing understanding in forensic pathology, emphasizing the evolving role of glass in fatal incidents.

Preparing Educators of Gifted and Talented Students to Decolonize Children’s Literature

As we write this paper in late 2023, Advanced Placement (AP) Black history, psychology courses and the use of diverse literature written for children and young adults is being banned by many school districts across the United States. Educators are being threatened, sanctioned, reprimanded, and fired. Despite this, some teachers stand steadfast in their commitment to pedagogies that use authentic literature about and by diverse historians, authors, social activists, and researchers, to name a few. In this article, we discuss the importance of gifted and talented (GATE) being taught Black history and culture that centers diverse literature that recognizes, respects, and celebrates similarities and differences within and across cultures including ethnicity, nationality, age, gender, gender expression, sexual orientation, socioeconomic status, geographic location, language, and religion, and physical, cognitive, and emotional ability. We do this within the frameworks of children’s literature as a site for decolonization and Bishop’s metaphor of “mirrors, windows, and sliding glass doors” (Bishop, 1990). While acknowledging that many GATE students are avid readers, we maintain that all children benefit from education that includes diverse literature and share recommendations for change.

Harry Potter: A Pedagogical Tool to Teach Diversity, Equity, Inclusion, and Advocacy

Since its conception, the Harry Potter franchise has become a cultural phenomenon which transgresses national borders. As many Potter fans struggle with how to manage their fandom in the face of author J.K. Rowling’s transphobic stance, the book series may ironically and more specifically be used to improve attitudes toward the LGBTQ + community. By using academic theory–such as Rudine Sims Bishop’s concept of mirrors, windows, and sliding glass doors–and specific examples of application in a classroom environment, this paper shows that the Potter books may be offered as powerful pedagogical tools to positively affect the attitudes of "insiders" toward "outsiders." This essay classifies LGBTQ + and BIPOC (Black, Indigenous, and people of color) populations as "outsiders," and non-LGBTQ + and non-BIPOC groups as "insiders," and it cites specific case study evidence in Latin America to signify the importance of this issue on a global scale.

Representation in Children’s Book Council of Australia Early Childhood and Picture Book Awarded Books (2018-2020)

The call for more diversity in children’s literature has increased over the past decade. Many researchers draw on Rudine Sims Bishop’s theory of Windows, Mirrors, and Sliding Glass Doors (1990) to argue that children need to be able to see their lives reflected in the media they consume, not just as caricatures or tokenistic characters, but as protagonists and everyday people. The prizing of children’s literature acts as a stamp of approval for what is considered quality literature, and often results in an undiscerning market that purchases texts simply because of their awarded prize. The Children’s Book Council of Australia (CBCA) Book of the Year award is one of the most prestigious literary awards available in the country, particularly for younger readers. This critical content analysis examines the winners, honoured, and short-listed texts for the Book of the Year awards in the Picture Book and Early Childhood categories for the years 2018-2020. The analysis found that the majority of the texts reinforce the current social and cultural discourse of the straight, white, cis-gendered, able-bodied male. Given the social and cultural impact of the CBCA awards, it is essential that the discourses and ways of being that are represented in the awarded texts are critically investigated to ensure they are representative of their readership and do not perpetuate a damaging message to readers about their or others’ identity.

Numerical Analysis of Air Flow in an Industrial Refrigeration System and Its Effect on Energy Consumption

Refrigerated display cabinets as a type of cooling system is preferable commonly in food shops and grocery store to prevent foods from warm air. They do not have much more efficient compared to the cabinets with glass doors because of the interactions between air curtain. This paper presents experimental and numerical methods to seek energy performance of the horizontal refrigerated display cabinets in terms of design parameters. Two geometry with/without airfoil were designed and evaluated the effects of discharge velocity to create more efficient air curtain. 2D Computational Fluid Dynamics (CFD) model was performed to assess the effect of discharge flow on the cooling load performance of the horizontal display cabinet. The results showed that the airfoil design has increased the efficiency of the air curtain with achieving a more effective air curtain, resulted in mitigation of the ambient warm air infiltration into the cabinet. The return air temperature of the cabinet with airfoil decreased from 272.45 K to 270.62 K compared to the one without airfoil due to more effective air curtain. In this way, the cooling capacity of the refrigeration system has been decreased by 3.82% with airfoil usage. It is also concluded that the air temperature inside the cabinet and the cooling capacity have been decreased by 3.5°C and 2.82%, respectively when Case 7 for used the new type airfoil and Case 1 with the same air velocity are compared.
