Radiant Conditioning Retrofitting for Residential Buildings

In order to achieve Australia’s greenhouse gas emissions reduction targets, a majority of the existing residential building stock in Australia will require retrofitting in favour of energy-efficient solutions. This paper considers retrofitting for conditioning to be one of the most straightforward and offers the greatest potential to deliver significant comfort and energy-saving results. Radiant conditioning systems are not new, yet some game-changing innovations have taken place over the last decade that may require an entire paradigm shift in the manner we condition our buildings. The reiteration of the principle ‘thermally active systems’ suggests that our buildings need to accommodate these systems into the fabric of building components. However, extremely few products and/or innovative solutions for doing such seem to be provided by the industry. We seem incompetent with solutions that are not costing the Earth, insulating, lightweight, and offering an instant response time to conditioning. We still have the concept embedded in our minds that radiative systems consist of heavy ‘combat’ construction with time lags of a day or two and that they are very costly to implement, especially if we are to retrofit a project. The purpose of this paper is to rectify and change our understanding of radiant systems, namely through a review of the existing technology and its recent advancements. It intends to introduce the fact that radiant systems can become highly reactive, responsive, and thermally dynamic conditioning systems. Lightweight radiant systems can be 40% more energy-efficient than common air conditioners and can respond in less than 15 min rather than in the hours required of heavy radiant systems. Thus, an insulated, lightweight radiant system is ideal for retrofitting residential buildings. Furthermore, this paper supports and introduces various systems suited to retrofitting a residential building with hydronic radiant systems.

Comparison of Hospital Consultation and Summer Camp Lifestyle Intervention Programs for Sustained Body Weight Loss in Overweight/Obese Greek Children

Two lifestyle intervention programs of a health initiative named “Evrostia” were conducted at (a) an outpatient obesity clinic of a children’s hospital and (b) summer camp (SC), respectively. Thirty overweight/obese children were randomly selected to participate in each intervention arm to assess the efficacy of the SC intervention and its possible superiority over usual hospital consultation (HC) practice. There was a statistically significant decrease in body weight (BW), and body mass index (BMI) in both programs. A higher duration of reduced BW was observed in the SC compared to HC intervention. Regarding the nutritional behavior, there was a significant increase in the consumption of breakfast, fruit and vegetables, and a reduction in the consumption of beverages and sweets in the SC group. A significant increase in the hours of weekly physical activity was also observed in children of the SC program. The comparison between the two lifestyle intervention programs showed that the SC program improved nutritional behaviors and physical activity and promoted longer preservation of BW loss than that of the HC program. Thus, the holistic and experiential approach of the SC program was more successful in the treatment of overweight and obesity in children than a conventional HC program.

Physician Burnout and the Electronic Health Record Leading up to and During The First Year of COVID-19: A Systematic Review (Preprint)

BACKGROUND Physician burnout was first identified in 1974, and it has been particularly prevalent during the first year of the pandemic. OBJECTIVE To objectively analyze the literature over the last five years for empirical evidence of burnout incident to the EHR and to identify barriers, facilitators, associated patient satisfaction to using the EHR to improve symptoms of burnout. METHODS No human subjects were used in this review, however 100% of participants in studies analyzed were adult physicians. Four research databases and one targeted journal were queried for studies commensurate with the objective statement from January 1, 2016 through January 31st 2021 (n=25). RESULTS The hours spent in documentation and workflow are responsible for the sense of loss of autonomy, lack of work-life balance, lack of control of one’s schedule, cognitive fatigue, a general loss of autonomy and poor relationships with colleagues. Researchers have identified training, local customization of templates and workflow, and the use of scribes to alleviate the administrative burden of the EHR and decreased symptoms of burnout. CONCLUSIONS The solutions provided in the literature only addressed two of the three factors, workflow and documentation time, but not the third, usability. Practitioners and administrators should focus on the former two factors because they are within their sphere of control. EHR vendors should focus on empirical evidence to identify usability features with the greatest impact to improve. Researchers should design experiments to explore solutions that address all three factors of the EHR that contribute to burnout. INTERNATIONAL REGISTERED REPORT RR2-10.2196/15490

Diurnal variation of outgoing longwave radiation derived from I NSA T-I B data

In this paper, 3-hourly values of Outgoing Long wave Radiation (OLR) for the years 1987 .to 1990 over the Indian Ocean region, derived from'1NSAT-IB VHRR observations, have been used to study the patterns of diurnal variation of OLR. The nature of the diurnal variations over different regions such as desert, ocean, monsoon area and equatorial trough in four representative months of the year is discussed. The variations in the diurnal range of OLR and the hours of occurrence of OLR minimum and maximum, are also presented.Daily means of TNSAT OLR using all.eight 3-hour samples and four different pairs of. 12-hour samples were computed. Results show that they are highly correlated. However, averages made with OLR values corresponding to 0230 and 1430 local time are slight underestimates compared to the 8-sample averages, whereas averages based upon 0830 and 2030 local time are slight overestimates.

Kata Stichon Hymnography in the East Slavic Tradition

The kata stichon hymns are a peculiar genre of hymnography occurring as part of nocturnal prayer in early sources for the Byzantine Liturgy of the Hours. The use of these hymns in traditions on the Byzantine periphery remains in need of study. In this paper, the authors identify kata stichon hymns translated into Church Slavonic found in early East Slavic Horologia as well as in later Slavonic collections of private prayer used in Russia up to the 17th century. The authors also identify hymns with no known Greek analogs, as well as hymns reflecting the kata stichon genre composed in Church Slavonic. The liturgical function of these hymns is studied and hypotheses are proposed for their origin and continued popularity in Russian nocturnal worship and private cell prayer.

Fermentation Parameters of Suero Costeño Elaborated with Lactic Acid Bacteria Strains

Studying the fermentation parameters of "Suero Costeño" was the focus of this research, considered a traditional product in the Caribbean region of Colombia, inoculated with lactic acid bacteria Lactococcus lactis subsp. Lactis (ATCC29146) and Lactobacillus paracasei subsp. paracasei (ATCC 334). It was found that the percentage of lactose decreased progressively during the hours of fermentation, with a minimum lactose value of 3.1% at 15 h for the samples of Suero Costeño with L. lactis, while for L. paracasei the percentage of lactose was 3.4%. L. paracasei the percentage of lactose was 3.4%; on the other hand, the pH, which is a limiting factor in the fermentation process, was reported to have a considerable reduction in the samples with L. lactis in comparison with L. paracasei, at the end of the fermentation process at 15 h, with values of 4.3 and 4.5, respectively. Finally, the sensory evaluation allowed establishing that the Suero Costeño with L. lactis obtained similar values to that produced in a traditional way, and therefore its use can be recommended in this type of dairy products as a starter culture.

A Nation in Crisis... in Three Acts

A dramatic, spoken-word performance based on a detailed examination of the text of more than 1.7 million tweets concerning coronavirus and covid that were sent during the hours surrounding the president's declaration of emergency on March 13, 2020 including the transcript of the remarks made at the Rose Garden press conference.

Microphysical process of precipitating hydrometeors from warm-front mid-level stratiform clouds revealed by ground-based lidar observations

Mid-level stratiform precipitations during the passage of warm fronts were detailedly observed on two occasions (light and moderate rain) by a 355 nm polarization lidar and water vapor Raman lidar, both equipped with waterproof transparent roof windows. The hours-long precipitation streaks shown in the lidar signal (X) and volume depolarization ratio (δv) reveal some ubiquitous features of the microphysical process of precipitating hydrometeors. We find that for the light-rain case precipitation that reaches the surface begins as ice-phase-dominant hydrometeors that fall out of a shallow liquid cloud layer at altitudes above the 0 ∘C isotherm level, and the depolarization ratio magnitude of falling hydrometeors increases from the liquid-water values (δv<0.09) to the ice/snow values (δv>0.20) during the first 100–200 m of their descent. Subsequently, the falling hydrometeors yield a dense layer with an ice/snow bright band occurring above and a liquid-water bright band occurring below (separated by a lidar dark band) as a result of crossing the 0 ∘C level. The ice/snow bright band might be a manifestation of local hydrometeor accumulation. Most falling raindrops shrink or vanish in the liquid-water bright band due to evaporation, whereas a few large raindrops fall out of the layer. We also find that a prominent δv peak (0.10–0.40) always occurs at an altitude of approximately 0.6 km when precipitation reaches the surface, reflecting the collision–coalescence growth of falling large raindrops and their subsequent spontaneous breakup. The microphysical process (at ice-bright-band altitudes and below) of moderate rain resembles that of the light-rain case, but more large-sized hydrometeors are involved.
