Сoncerning the Question of Maintenance and Renewal of Cultural Landscape Around Wooden Church of Holy Spirit in Potelycz Village
Показано краєзнавчу цінність села Потелича Жовківського району Львівської області з дерев’яною церквою Святого Духа. Запропоновано сучасні способи відновлення (зокрема нові технології тривимірної візуалізації) та збереження ландшафту навколо сакральної дерев’яної пам’ятки.In the work there was shown local history value of Potelycz village of Zhovkva region, Lviv district taking into account wooden church of Holy Spirit. Contemporary techniques of restoration (including innovative 3D visualization technologies) and maintenance of landscape around sacral wooden monument were presented as well
A case study of the patient wait experience in an emergency department with therapy dogs
The quality of patient healthcare is a growing concern in Canada’s hospital emergency departments (ED) due to increasing wait times and associated adverse outcomes. A developing body of literature indicates that therapy dogs can positively impact the patient experience. In 2016, members of our team partnered with the Royal University Hospital (RUH) in Saskatchewan to become the first ED in Canada to integrate a visiting therapy dog to positively impact the patient wait experience. The aim of this preliminary case study was to examine if and how this unique initiative impacted patients’ feelings during their ED wait. A brief questionnaire was completed with one-hundred and twenty-four patients pre and post-therapy dog visit and a research observer documented the encounters. Quantitative and qualitative analysis of the data revealed that visiting with a therapy dog in the ED appeared to improve patients’ feelings. Specifically, patients’ perceived comfort levels increased and their distress levels decreased, and the encounters were considered by patients to be a welcome distraction from the stressful ED environment. Our team, comprised of clinicians, researchers, therapy dog handlers and patient advocates documented the advantages and challenges of implementing the initiative. The outcomes support further study of patients’ wait time experiences in the ED and the utility of a visiting therapy dog
The Geozoic Supereon
Geological time units are the lingua franca of earth sciences: they are
a terminological convenience, a vernacular of any geological conversation,
and a prerequisite of geo-scientific writing found throughout in
earth science dictionaries and textbooks. Time units include terms
formalized by stratigraphic committees as well as informal constructs
erected ad hoc to communicate more efficiently. With these time terms
we partition Earth’s history into utilitarian and intuitively understandable
time segments that vary in length over seven orders of magnitude:
from the 225-year-long Anthropocene (Crutzen and Stoermer, 2000) to
the ,4-billion-year-long Precambrian (e.g., Hicks, 1885; Ball, 1906;
formalized by De Villiers, 1969)
The proteasome inhibitor MG-132 sensitizes PC-3 prostate cancer cells to ionizing radiation by a DNA-PK-independent mechanism
BACKGROUND: By modulating the expression levels of specific signal transduction molecules, the 26S proteasome plays a central role in determining cell cycle progression or arrest and cell survival or death in response to stress stimuli, including ionizing radiation. Inhibition of proteasome function by specific drugs results in cell cycle arrest, apoptosis and radiosensitization of many cancer cell lines. This study investigates whether there is also a concomitant increase in cellular radiosensitivity if proteasome inhibition occurs only transiently before radiation. Further, since proteasome inhibition has been shown to activate caspase-3, which is involved in apoptosis, and caspase-3 can cleave DNA-PKcs, which is involved in DNA-double strand repair, the hypothesis was tested that caspase-3 activation was essential for both apoptosis and radiosensitization following proteasome inhibition. METHODS: Prostate carcinoma PC-3 cells were treated with the reversible proteasome inhibitor MG-132. Cell cycle distribution, apoptosis, caspase-3 activity, DNA-PKcs protein levels and DNA-PK activity were monitored. Radiosensitivity was assessed using a clonogenic assay. RESULTS: Inhibition of proteasome function caused cell cycle arrest and apoptosis but this did not involve early activation of caspase-3. Short-time inhibition of proteasome function also caused radiosensitization but this did not involve a decrease in DNA-PKcs protein levels or DNA-PK activity. CONCLUSION: We conclude that caspase-dependent cleavage of DNA-PKcs during apoptosis does not contribute to the radiosensitizing effects of MG-132

OPTIMAL CONTROL PROBLEM OF SOME DIFFERENTIAL INCLUSION AND APPROXIMATION
In this paper we present the optimal control problem governed by a variational inclusion with the monotone operator and a quadratic costfunctional. We apply standart Galerkin method to the approximation of the problem. After giving some results on the existance of optimal control we shall prove the existance of weak condensation points of a set of solution of approximate problems. Each of these points is a solution of the initial optimization problem. Finally we shall give a simple example using the obtaned results
