Gradual typing combines static and dynamic typing in the same program. One would hope that the performance in a gradually typed language would range between that of a dynamically typed language and a statically typed language. Existing implementations of gradually typed languages have not achieved this goal due to overheads associated with runtime casts. Takikawa et al. (2016) report up to 100×...

AIM To compare T-tube and pressure support ventilation (PSV) as two methods of weaning patients from mechanical ventilation. METHODS A randomized prospective study included 260 patients who received mechanical ventilation for more than 48 h, and who were admitted to the intensive care unit (ICU) at Dr. Josip Bencevic General Hospital in Slavonski Brod, between August 1999 and October 2000. Af...

The data were collected from 1992 to 2009 in Burri, White Boni and Black Boni sheep maintained at the Regional Research Station in the Central Highlands of Yemen. Data were analyzed to study the effects of environmental and genetic factors on body weight and growth rate from birth to weaning. The least square means for body weights (BW) were 2.54, 2.18 and 2.26 kg for birth; 12.49, 10.58 and 11...

Numerous studies have documented the cariogenic effects of prolonged or nocturnal bottle feeding in children. Guidelines prepared by the American Academy of Pediatrics (AAP) suggest that pediatricians advise parents to begin bottle weaning when their child is approximately nine months of age and accomplish weaning soon after the first birthday. However, little information exists concerning the ...

Being able to combine static and dynamic typing within the same language has clear benefits in order to support the evolution of prototypes or scripts into mature robust programs. While being an emblematic dynamic object-oriented language, Smalltalk is lagging behind in this regard. We report on the design, implementation and application of Gradualtalk, a gradually-typed Smalltalk meant to enab...

We present a method to support the gradual evolution of secure scripts by formalizing an extension of the simply-typed lambda calculus that provides information flow constructs. These constructs allow initially insecure programs to evolve via targeted refactoring and to provide dynamic information flow guarantees via casts, as well as static information flow guarantees via labeled types.

Soon after parturition a lasting and mutual ewe–lamb bond is established. However, in an increasing number of intensive sheep farms, lambs are separated from the dam at an early age. When artificial rearing is applied lambs are often kept with mothers for 2 days to allow the ingestion of maternal colostrum and then abruptly removed from their dams. Thus, lambs experience a marked emotional stre...

BACKGROUND The recommended age of introduction of solids food to the diet of infants (weaning) has recently been increased in the UK to 6 months, but most babies are still weaned before the age of 4 months. AIMS To examine what predicts the age of weaning and how this relates to weight gain and morbidity using data from a population based cohort. METHODS Parents of 923 term infants born in ...

Weanling pigs (n = 176), 21 to 26 d of age (average initial weight, 7.1 kg), were used to evaluate the effects of weaning time (evening vs morning) and feeding time (immediate vs delayed) on postweaning performance. Pigs were randomly allotted within litters to four treatments in a 2 x 2 factorial arrangement as follows: 1) weaning at 2000 with immediate feeding, 2) weaning at 2000 with 12-h de...

BACKGROUND The right nutrition from the start of a pregnancy to the child's second birthday has a profound impact on the future health, wellbeing, and success of a child. This can be achieved through proper maternal nutrition during pregnancy, exclusive breastfeeding, and appropriate weaning practice. OBJECTIVE This study was aimed at assessing appropriate weaning practice and associated fact...
