In predictive microbiology, the relation between the lag time (Lag) and the generation time (Tg) is commonly assumed to be proportional, as long as the pre-incubation environmental conditions remain constant. This relation was statistically examined in nine published datasets. For every dataset, it was roughly proportional. However, a more advanced study showed that the ratio Lag/Tg was not tot...

This study explores the influence of board independence, board size, CEO duality, board diligence, board financial expertise and presence of audit committee as well as the type of sector on the timeliness of financial reports among selected Jordanian companies. The timeliness of the financial reports is measured by audit report lag (ARL) and management report lag (MRL). This study covers 112 fi...

Based on the current serious inflation problem at home and abroad, this thesis uses the data of broad money supply and monthly price during 1998 to 2008 and makes an empirical study on Chinese inflation time lag. Through the estimation of the Polynomial Distributed Lags Model, the author concludes that: money supply’s change has significant time lag effect on price’s change, and the lag time is...

The growth of Salmonella typhimurium (ATCC 14028) on the surface of autoclaved ground chicken breast and thigh burgers incubated at constant temperatures from 8 to 48 degrees C in 2 degrees C increments was investigated and modeled. Growth curves at each temperature were fit to a two-phase linear primary model to determine lag time (lambda) and specific growth rate (mu). Growth of S. typhimuriu...

OBJECTIVES The aim of this study was to determine the temporal relation between the use of antibiotics and alcohol-based hand rubs (ABHRs) and the incidence of methicillin-resistant Staphylococcus aureus (MRSA) and Clostridium difficile. METHODS An interventional time-series analysis was performed to evaluate the impact of two promotion campaigns on the consumption of ABHRs and to assess thei...

This research quantifies the lag effects and vulnerabilities of temperature effects on cardiovascular disease in Changsha--a subtropical climate zone of China. A Poisson regression model within a distributed lag nonlinear models framework was used to examine the lag effects of cold- and heat-related CVD mortality. The lag effect for heat-related CVD mortality was just 0-3 days. In contrast, we ...

Sleep disturbances are an all-too-familiar symptom of jet lag and a prime source of complaints for transmeridian travelers and flight crews alike. They are the result of a temporary loss of synchrony between an abruptly shifted sleep period, timed in accordance with the new local day-night cycle, and a gradually reentraining circadian system. Scheduled exposure to bright light can, in principle...

The aim of the present work is to design an oral time release tablet by press coating method to achieve a distinct predetermined lag time. In this study Metoprolol tartrate was selected as the model drug. The outer shell was formulated with different weight ratios of Hydroxy propyl methyl cellulose K100M and Ethyl cellulose to achieve a release profile with pre determined lag time. The lag time...
