    Project Home Again is a development in New Orleans, LA created to provide new homes to victims of Hurricane Katrina. Building Science Corporation acted as a consultant for the project, advocating design strategies for durability, flood resistance, occupant comfort, and low energy use while maintaining cost effectiveness. These techniques include the use of high density spray foam insulation, LoE3 glazing, and supplemental dehumidification to maintain comfortable humidity levels without unnecessary cooling

    The rapid development of modern technologies has brought enormous benefits to today's society in all areas of life. On the one hand, they have a positive effect on people's relationships, learning, and development. On the other hand, the incorrect use of electronic devices can cause health damage and serious problems. In recent years, the use of digital devices has increased among students, highlighting the problem of digital addiction. This study aimed to observe the problems of spinal pain associated with the use of mobile phones by students in schools and to find constructive solutions to turn mobile phones into an effective learning tool to be used only in the classroom. The method used in this study was to apply questionnaires to a sample of 506 students from Arad County. The results of this study showed that students in the study group are addicted to the internet and social networks, and also confirmed that some of them cannot experience all this without sacrificing their physical and mental health. In conclusion, educational and policy measures to combat digital addiction are urgently needed worldwide. Schools should implement comprehensive digital literacy programs to educate students about the risks of excessive use of digital devices and promote healthy online behaviors

    Leveraging Limited Scope for Maximum Benefit in Occupied Renovation of Uninsulated Cold Climate Multifamily Housing

    This project examines a large-scale renovation project within a 500 unit, 1960's era subsidized urban housing community. This research focuses on the airflow control and window replacement measures implemented as part of the renovations to the low-rise apartment buildings. The window replacement reduced the nominal conductive loss of the apartment enclosure by approximately 15%; air sealing measures reduced measured air leakage by approximately 40% on average

    A 31-year-old single man (AB) sought neuropsychiatric consultation for treatment-resistant motor and vocal tics. He described himself expressing a total of 24 different tics, mainly facial twitches (eye blinking, raising eyebrows, mouth opening, lips licking, stereotyped grimacing) and inappropriate utterances (grunting, throat clearing, sniffing), since the age of 7. There appeared to be no family history of tic disorder. He reported occasional utterance of swear words in contextually inappropriate situations (coprolalia), and the urge to copy other people’s movements (echopraxia). Other tic-associated symptoms included self-injurious behaviours and forced touching of objects. A.B. met both DSM-IV-tr and ICD-10 criteria for Tourette syndrome, and also DSM-IV-tr criteria for attention deficit hyperactivity disorder (combined type) in childhood

    Proven Performance of Seven Cold Climate Deep Retrofit Homes

    Get PDF
    Seven test homes located in Massachusetts are examined within this report. The retrofit strategies of each home are presented along with a comparison of the pre- and post-retrofit airtightness achieved by the group. Pre- and post-retrofit utility bills were collected; energy models were used to estimate pre-retrofit energy use when bills were unavailable

    Development of Two Heliodon Systems and Recommendations for their Use

    Get PDF
    Heliodons aid the building design process by allowing the simulation of different solar angles with respect to physical scale models. At MIT, two different variations of this setup are being developed. The first one consists of a small, portable heliodon that is manually operated, and meant for use outdoors with the real sun and sky. The second is a larger indoor setup that consists of a computer-controlled moving table exposed to a stationary light source. A computer interface allows the designer to automatically take useful sets of model photos from a camera positioned next to or inside a model. Both approaches are presented in this paper and their limitations, causes of inaccuracy and potentialities are discussed based on experimental verification and through Radiance simulations. The results of a usability study with student volunteers and a case study on an existing research space on the MIT campus are also presented
