Chronic infections caused by persistent pathogens represent an important health problem. Here, we establish a simple practical mouse Salmonella infection model for identifying bacterial maintenance functions that are essential for persistency. In this model, a substantial fraction of Salmonella survived even several days of treatment with a potent fluoroquinolone antibiotic indicating stringenc...
The present study examines the benefits of instructional animations in a collaborative learning situation. We investigated the interactions that occur during collaborative learning from different materials: animated versus static pictures, both with or without persistency of information. The animation factor had no effect on the types of interactions but the persistency of information led to fe...
Persistent objects are useful for applications that require data structures to be maintained across multiple executions. This paper describes pobj, a lightweight facility for providing persistent objects. The library offloads the actual backing store management to lladd, an open-source implementation of the ARIES recovery algorithm, and memory management to external libraries. This layered appr...
The overlap and interlinkage of dizzy symptoms in patients with psychiatric and vestibular vertigo/dizziness disorders is the subject of an ongoing debate. In a one-year follow up in 68 patients with vestibular vertigo syndromes, the persistency of vertigo and dizziness symptoms was examined and correlated with vestibular parameters and results from a psychiatric evaluation. Patients with vesti...
Twelve spring-calving and twelve winter-calving cows were managed for extended lactation cycles of 18-months duration, with the former group then completing a second extended lactation. Half of the cows were fed according to standard management practice for the herd; the other half received supplementary concentrate from week 9 of lactation onwards. Commencing at the same time, half of the udde...
Variace / covariance components of 227118 first lactaiom test-day milk yield records belonged to 31258 Iranian Holstein cows were estimated using nine random regression models. Afterwards, different measures of persistency based on estimation breeding value were evaluated. Three functions were used to adjust fixed lactation curve: Ali and Schaeffer (AS), quadratic (LE3) and cubic (LE4) order of...
ABSTRACT Background: The emotional bond that a mother feels towards her infant is critical to their social, emotional, and cognitive development. This concept has a major influence on an infant’s future health, and growth, so the assessment of parental-fetal attachment and related factors is of great importance. This study aimed to examine the effect of psychological intervention on attachment ...
The GAUDI software architecture, designed in the context of the LHCb experiment, maintains separate and distinct descriptions of the transient and persistent representations of the data objects. One of the motivations for this approach has been the requirement for a multitechnology persistency solution such that the best-adapted technology can be used for each category of data: raw event data, ...
The virtually synchronous execution model provides an appropriate support for developing distributed applications, assuming a crash failure model. Synchronization points are only set when a view change arises, guaranteeing an efficient execution of such reliable applications. Its programming model is similar to that of a centralized application, but not identical. However, a crash model is not ...
