The operating efficiency of heating, ventilation and air conditioning (HVAC) system is critical for building energy performance. Demand-based control is an efficient HVAC operating strategy, which can provide an appropriate level of HVAC services based on the recognition of actual cooling "demand." The cooling demand primarily relies on the accurate detection of occupancy. The current researches of demand-based HVAC control tend to detect the occupant count using cameras or other sensors, which often impose high computation and costs with limited real-life applications...

A series of novel pyranoquinolinone-based Schiff's bases were designed and synthesized. They were evaluated for topoisomerase IIβ (TOP2B) inhibitory activity, and cytotoxicity against breast cancer cell line (MCF-7) for the development of novel anticancer agents. A molecular docking study was employed to investigate their binding and functional properties as TOP2B inhibitors, using the Discovery Studio 2.5 software, where they showed very interesting ability to intercalate the DNA-topoisomerase complex. Compounds 2a , 2c and 2f showed high docking score values (82...

PURPOSE: A major advantage of guided implant surgery using 3-dimensionally printed guides is the ability to perform accurate flapless surgery. A drawback of a flapless technique is the inability to manipulate soft tissue to ensure sufficient gingiva around the implant. The purpose of this study was to determine how often flapless surgery using surgical guides results in less than 2 mm of keratinized tissue surrounding the implant. MATERIALS AND METHODS: This retrospective analysis included 27 maxillary and 27 mandibular implant sites that underwent treatment planning for implant-guided surgery using 3Shape Implant Studio (3Shape, Copenhagen, Denmark)...

Objective: To evaluate the transverse displacement, stress distribution and tendency of change in tooth, alveolar bone and mid-palatal suture using three kinds of rapid maxillary expansion methods. Methods: Cone-beam CT image data was obtained by scanning skulls of a volunteer. Three-dimensional models of maxillary complex were re-established using Mimics and Geomagic Studio and models of Hyrax expander, Haas expander and miniscrew-assisted rapid palatal expander (MARPE) were established using ANSYS Workbench...

BACKGROUNDS: Gallstone disease and cholecystectomy have been uncommon in paediatric patients and associated with haemolytic disease and prematurity. Many countries have observed an increase in the prevalence of paediatric gallstones and cholecystectomy with increasing childhood obesity. The purpose of this study was to determine any trend in prevalence in Australian children and the role of obesity. METHODS: Chart review was conducted for patients undergoing cholecystectomy under 18 in 25 years between 1992 and 2016...

OBJECTIVE: Burnout is a phenomenon with profound negative effects on the US healthcare system. Little is known about the relationship between time spent working on electronic health record (EHR) and burnout among psychiatry residents. The purpose of this study is to generate preliminary data on EHR use and burnout among psychiatry residents and faculty. METHODS: In August 2017, psychiatry residents and faculty at an academic medical center were given the Maslach Burnout Inventory (MBI), a standardized measurement tool for burnout, and a survey of factors related to EHR use and potential risk factors for burnout...

PURPOSE: To present Poisson exact goodness-of-fit tests as alternatives and complements to the asymptotic u-test, which is the most widely used in cytogenetic biodosimetry, to decide whether a sample of chromosomal aberrations in blood cells comes from an homogeneous or inhomogeneous exposure. MATERIALS AND METHODS: Three Poisson exact goodness-of-fit test from the literature are introduced and implemented in the R environment. A Shiny R Studio application, named GOF Poisson, has been updated for the purpose of giving support to this work...

The natural product flavonoid demonstrates an extensive sort of pharmacological properties including antimicrobial activity. Although its Pseudomonas aeruginosa inhibition has been discovered, no target for action against flavonoid has been revealed to date. The anti - P. aeruginosa activity of the 2 - (3', 4' dihydroxy-phenyl) - 3, 5, 7-trihydroxy-chromen-4-one isolated from T. decandra was evaluated by disc diffusion and minimum inhibitory concentration methods. The molecular docking of the flavonoid isolated from T...

The implementation of wireless sensor networks (WSNs) for monitoring the complex, dynamic, and harsh environment of underground coal mines (UCMs) is sought around the world to enhance safety. However, previously developed smart systems are limited to monitoring or, in a few cases, can report events. Therefore, this study introduces a reliable, efficient, and cost-effective internet of things (IoT) system for air quality monitoring with newly added features of assessment and pollutant prediction. This system is comprised of sensor modules, communication protocols, and a base station, running Azure Machine Learning (AML) Studio over it...

Introduction: Deficiency of growth hormone (GH) in absence of pituitary injuries is one of the causes of short stature and of the non organic failure to thrive (NOFTT) condition. Advances in developmental psychology have highlighted the role of emotions and caregiving behaviors in the organization of child’s personality and psychobiology, with the mother-son attachment bond being considered a fundamental developmental experience. The objective of the present preliminary study was to assess whether there are significant correlations between attachment patterns and GH levels in a sample of subjects with NOFTT...
