Mathematical models are constructed to investigate the population dynamics of Verocytotoxin-producing Escherichia coli (VTEC) serogroups O26 and O103 in two different calf cohorts. We compare the epidemiological characteristics of these two serogroups within the same calf cohort as well as the same serogroups between the two calf cohorts. The sources of infection are quantified for both calf co...

purpose we intended to determine predictor variables of anthropometry and training for marathon race time in recreational female runners in order to predict marathon race time for future novice female runners. methods anthropometric characteristics such as body mass, body height, body mass index, circumferences of limbs, thicknesses of skin-folds and body fat as well as training variables such ...

Brucellosis is an infectious disease of worldwide distribution, which has a great economic impact due to the productive and reproductive losses that it causes, in addition serious public health problem. The aim this study estimate losses, through financial analysis, caused by bovine brucellosis province Carchi, over one-year period. A random sampling was used determine prevalence area, where 29...

Factors affecting calving interval (CI) in double-muscled Belgian Blue (DMBB) beef cows were investigated with regard to the BW yield (BWY) of the cow-calf pair, using 834 CI records from 386 females with parities 1 to 6. The effect of parity and CI on BWY was also studied. Cow-calf pair BWY was defined as calf birth weight plus dam BWY per CI. CI (mean±s.e.: 404±1.9 days) was affected by parit...

Two phase commit PC is used for coordinating the commitment of transactions in distributed systems The preferred PC optimization is the presumed abort variant which reduces the number of messages when transac tions are aborted and eliminates the coordinator s need to retain information about aborted transactions The presumed commit PC variant provides a larger message reduction but its coordina...

Two phase commit (2PC) is used to coordinate the commitment of transactions in distributed systems. The standard 2PC optimization is the presumed abort variant, which uses fewer messages when transactions are aborted and allows the coordinator to forget about aborted transactions. The presumed commit variant of 2PC uses even fewer messages, but its coordinator must do additional logging. We des...

The ECG done on his arrival at the emergency room (see questions) shows (i) sinus tachycardia, (ii) a QRS complex that ends with a positive deflection (or prominent J wave) that is, a rsR9 pattern in V1 and V2, and (iii) an elevated downsloping ST segment ending in a small negative T-wave deflection. This ECG pattern in someone with a history of syncopy and documented ventricular fibrillation/a...
