BACKGROUND Septic shock is a common and often devastating syndrome marked by severe cardiovascular dysfunction commonly managed with vasopressors. Whether markers of heart rate complexity before vasopressor up-titration could be used to predict success of the up-titration is not known. METHODS We studied patients with septic shock requiring vasopressor, newly admitted to the intensive care un...

Objective: Garlic is a plant has been used as a flavor, and anti-microbial and anti-diarrheal agent. Infectious bronchitis virus (IBV) is a coronavirus. The available vaccines against IBV cannot cover new variants. This study evaluated the inhibitory effects of garlic extract on IBV.  Materials and Methods: The constituents of garlic extract were detected by gas chromatography. This study was d...

In this paper, we describe our efforts in the development of an environment that supports the modeling, analysis and simulation of processes associated with software system acquisition activities. Software acquisition is generally a large, multi-organization endeavor concerned with the funding, management, engineering, system integration, deployment and long-term support of large software syste...

The most commonly used technique for water content determination is Karl-Fischer titration with electrometric detection, requiring specialized equipment. When appropriate equipment is not available, the method can be performed through visual detection of a titration endpoint, which does not enable an analysis of colored samples. Here, we developed a method with spectrophotometric detection of a...

Roughly 35 three-person teams played the roles of user, customer, and developer in negotiating the requirements of a library information system. Each team was provided with a suggested set of stakeholder goals and implementation options, but were encouraged to exercise creativity in expanding the stakeholder goals and in creating options for negotiating an eventually satisfactory set of system ...
