The effects of dl-cathinone on milk intake and motor activity were investigated in bottle- and cannula-fed rats. Acute injections of cathinone produced dose-dependent increases in activity in both groups but only produced decreased intake in bottle-fed rats. With chronic injections, tolerance to the suppression of intake developed in the bottle-fed group, accompanied by decreased activity. Afte...

It is known that for every nonorientable surface there are infinitely many (large) snarks that can be polyhedrally embedded on that surface. We take a dual approach to the embedding of snarks on the Klein bottle, and investigate edge-colorings of 6-chromatic triangulations of the Klein bottle. In the process, we discover the smallest snarks that can be polyhedrally embedded on the Klein bottle....

The blue bottle experiment is a collective term for autoxidation reactions catalysed by redox indicators. The reactions are characterized by their repeatable cycle of colour changes when shaken/left to stand and intricate chemical pattern formation. The blue bottle experiment is studied based on calculated solution-phase half-cell reduction potential of related reactions. Our investigation conf...

The main results concern with the self maps on the Klein bottle. We obtain the Reidemeister numbers and the Nielsen numbers for all self maps on the Klein bottle. In terms of the Nielsen numbers of their iterates, we totally determine the minimal sets of periods for all homotopy classes of self maps on the Klein bottle.

In this paper, we shall characterize triangulations on the Klein bottle without K6-minors. Our characterization implies that every 5-connected triangulation on the Klein bottle has a K6-minor. The connectivity “5” is best possible in a sense that there is a 4-connected triangulation on the Klein bottle without K6-minors.

BACKGROUND Although glasses and bottles are frequently used as weapons in assaults, there is little knowledge on which prevention strategies can be based. DESIGN Scrutiny of a random sample of 1288 criminal injury compensation applications. OBJECTIVE To identify predictors and relative severity of glass and bottle injury. METHOD Injury site, severity, treatment, and demographic characteri...

OBJECTIVE To describe patterns of bottle-feeding across the first year postpartum and explore whether bottle-feeding trajectories are differentially associated with infant weight gain. METHOD Data came from 1291 mothers who participated in the Infant Feeding Practices Study 2. Mothers completed a prenatal questionnaire and monthly surveys of infant feeding and growth between birth and 12 mont...

To determine the optimal anaerobic companion bottle to pair with the BacT/ALERT (bioMerieux, Durham, N.C.) nonvented aerobic FA (FA) medium for recovery of pathogenic microorganisms from adult patients with bacteremia and fungemia, we compared the BacT/ALERT FN (FN) anaerobic bottle with the standard BacT/ALERT SN (SN) anaerobic bottle. Each bottle, FA, FN, and SN, was filled with 8 to 12 ml of...

BACKGROUND To prevent breastfeeding problems, cup-feeding has been recommended as a method of providing medically necessary supplemental feedings to breastfed infants. OBJECTIVES To compare amounts ingested, administration time, and infant physiologic stability during cup-, bottle-, and breastfeeding. DESIGN/METHODS A total of 98 term, healthy newborns were randomized to either cup-feeding ...

Once there was an immortal who lived in a bottle gourd and emerged each morning to sell medicine. Every night he returned to the bottle gourd to sleep. Curious about this strange behavior, a mortal followed him into the bottle gourd. There he found a spacious fairyland with landscapes of unearthly beauty. This story was told by Ge Hong, an important figure in the development of Taoism, in his f...
