Abstract In our days, energy issues belong to the most important problems facing the Earth and the solution may be expected partly from decreasing the amount of the energy used and partly from the increased utilisation of renewable energy resources. A substantial part of energy consumption is related to buildings and includes, inter alia, the use for cooling/heating, lighting and cooking purposes. In the view of the above, special attention has been paid to minimising the energy consumption of buildings since the late 1980s. Within the framework of that, the passive house was created, a building in which the thermal comfort can be achieved solely by postheating or postcooling of the fresh air mass without a need for recirculated air. The aim of the paper is to study the changes in the construction of passive houses over time. In addition, the differences between the geographical locations and the observable peculiarities with regard to the individual building types are also presented.

This paper provides an example of an innovative solution to program development that addresses the diverse needs of teacher educators throughout various geographical locations in Florida, through a collaborative multi-university, muti-agency teacher training program funded by one collaborative grant.   Innovation is driven out of need, and I will discuss how I identified the needs at my university and then utilized creativity and collaboration to network and obtain the grant, which then facilitated, developed, and taught in a new M.Ed. program in Arts and Academic Interdisciplinary Education.  Program content and delivery were both planned around the diverse student population within the multi-university collaboration, with each university designing diverse programs to address the specific needs of their population but with the same concept of arts integration.  Collaboration also occurred within each university: the College of Arts and Science and the College of Education.  In addition, teachers were required to collaborate as coaches in their schools to train and support others in increasing arts integration in their schools.

Background Physicians continue to practice in a very litigious environment. Some physicians try to mitigate their exposure to lawsuits by avoiding geographical locations known for their high incidence of medical malpractice claims. Not only are certain areas of the United States known to have a higher incidence of litigation, but it is also assumed that certain areas of the hospital incur a greater liability. There seems to be a medicolegal dogma suggesting a higher percentage of malpractice claims coming from patients seen in the emergency room (ER), as well as higher settlements for ER claims. Objective To determine if there is any validity to the dogma that a higher percentage of malpractice claims arise from the ER. Methods An analysis of common plastic surgery consults that result in malpractice claims was performed. The location where the basis for the lawsuit arose – the ER, office (clinic) or the operating room (OR) – was evaluated. The value of the indemnity paid and whether its value increased or decreased based on the location of the misadventure was evaluated. Results According to the data, which represented 60% of American physicians, there was a larger absolute number of malpractice claims arising from the OR, not the ER. However, the highest average indemnity was paid for cases involving amputations when the misadventure originated in the ER. Conclusions The dogma that a greater percentage of lawsuits come from incidents arising in the ER is not supported. However, depending on the patient's injury and diagnosis, a lawsuit from the ER can be more costly than one from the OR.

Image registration is important in geostationary weather satellites. Achieving consistent registration of the images with respect to the geographical locations on the Earth is here of interest. The consistency in the registration between the images is affected whenever the orbital inclination and eccentricity are not zero. The imaging payload has a two-axis scanning mirror to capture the Earth image. The above orbital effects together with scan mirror pointing direction are the factors that cause the misregistration. This paper presents an onboard algorithm that provides the scan compensation angles due to the above factors and achieves consistent registration. The compensation varies every second, which is the time taken for each scan. Hence it is preferred to have computations onboard than to have ground based bulk uplinks for the scan compensation. The paper presents an algorithm that is useful, say, when (i) the onboard computing capabilities are limited, (ii) the navigation accuracies are coarse and (iii) the image resampling is not preferred on the ground and the payload data are directly used for weather applications. The paper also discusses the tests that were carried on the onboard software in order to validate its performance in achieving the consistent registration before launch. This is done by using another independent software tool which is also described in detail. Image motion algorithm was invoked for a couple of days in INSAT 3DR. The atmospheric wind vector deduced directly from the satellite images is given at the end.

Abstract Tibetan hulless barley (“qingke” in Chinese) is a valuable food in Tibet. Purple qingke (PQK) and black qingke (BQK), two special pigmented types of hulless barley, have traditionally been widely cultivated and consumed in Tibet for thousands of years. The composition and contents of anthocyanins of two cultivars are unknown. This study aimed to explore the composition and contents of anthocyanins of two cultivars and their antioxidant capacities. Six anthocyanins were identified by ultra-performance liquid chromatography-quadrupole-time of flight mass spectrometry from barley, most of the anthocyanins were acylated by malonyl group. The total anthocyanin contents ranged from 141 to 2,304 μg/g in PQK and from 248.7 to 2902.9 μg/g in BQK. Furthermore, qingke has strong antioxidant activity against DPPH, ABTS˙+, and FRAP. Qingke may be useful for treating or preventing diseases caused by the overproduction of radicals.

Deicing of pavements is essential to ensure safe and timely movement of traffic in geographical locations where snow and ice events are anticipated. State and local municipalities employ brine solution with 23.3 wt% sodium chloride (NaCl) available in the form of rock salt to deice the pavements. Unlike water, the brine solution does not freeze until the temperature falls below −21.0 °C, i.e., the freezing point of water is depressed by −21.0 °C with the addition of 23.3 wt% NaCl. The depressed freezing point of the brine solution plays a key role in deicing pavements. Unfortunately, a further increase in rock salt content does not lower the freezing point of the brine solution. In this study, different combinations of agricultural products such as polyols including sorbitol, maltitol, and mannitol in brine (23.3 wt% of NaCl in water), and NaCl-juice (corn and beet juice) were investigated to achieve freezing point depressions below −21.0 °C for potential deicing applications in extremely cold areas. Different weight fractions of polyols-brine solutions ranging from 7.14% to 27.77% were considered, and corresponding freezing points were determined. While the sorbitol-brine solution exhibited the lowest freezing point of −38.1 °C at a higher concentration, the maltitol-brine solution exhibited a freezing point of −35.6 °C at the same concentration. Based on the °Brix value, beet juice had almost three times more soluble solids and a lower freezing point compared to corn juice. Adding 23.3 wt% of NaCl in 70% corn juice lowered the freezing point up to −23.5 °C.
