The BACTEC 16B resin medium was developed to detect bacteremia in patients receiving antimicrobial therapy. Over a 9-month period, we compared the efficacy of the BACTEC 16B bottle to the conventional aerobic BACTEC 6B bottle. Of a total of 1,524 sets of blood cultures, 79 yielded presumed pathogens. Of these 79 sets, 42 (53.2%) were positive in both the 16B and 6B bottles, 23 (29.1%) were posi...

Abstract: One of the most abundant and negative impacts on environment is plastic waste. PET (Polyethylene Terephthalate) bottle waste largest waste, has not been processed optimally. The purpose this research was to examine manufacture briquettes from mixed with natural materials, such as coconut shells wood sawdust starch adhesive. This uses an experimental method that begins carbonization pr...

The label on a bottle of pills says “Take one half pill daily.” A natural way to proceed is as follows: Every day, remove a pill from the bottle at random. If it is a whole pill, break it in half, take one half, and return the other half to the bottle; if it is a half pill, take it. We analyze the history of such a pill bottle.

Antimony is a regulated contaminant that poses both acute and chronic health effects in drinking water. Previous reports suggest that polyethylene terephthalate (PET) plastics used for water bottles in Europe and Canada leach antimony, but no studies on bottled water in the United States have previously been conducted. Nine commercially available bottled waters in the southwestern US (Arizona) ...

Solar Water Disinfection (SODIS) is a simple process used in developing countries to improve the quality of bacteria-contaminated drinking water. A previous study found that phthalate, an aromatic compound released by polyethylene terephthalate (PET) bottles upon UV-A irradiation, enhanced the germicidal activity of SODIS. In the current study, two possible mechanisms behind this observation we...

A single-step, extrusion-based process to depolymerize poly(ethylene terephthalate) (PET) is being investigated. The depolymeriza tion is effected by reacting ethylene glycol (EG) with the high molecular weight polymer (glycolysis). The ethylene glycol causes chain scission by attacking the ester linkages along the polymer backbone. The objective is to recover purified low molecular weight olig...

BACKGROUND Few studies have provided evidence to verify that bottle-feeding has negative effects on breastfeeding. There is insufficient evidence to support the practice of cup-feeding to supplement breastfeeding. However, it has been applied as a substitute for bottle-feeding to promote breastfeeding. The aims of this study were to explore the differences in infant sucking competence, infant s...

Oxygen saturation is lower during bottle feeding than during breastfeeding in preterm infants. Our objective was to compare two different bottle systems in healthy preterm infants before discharge in terms of SpO(2) and oral feeding efficiency (rate of milk intake). Infants without supplement oxygen needs were evaluated twice on the same day during two consecutive feeds, by the same nurse. Infa...

A study comparing the recovery of microorganisms from a transiently vented biphasic brain heart infusion medium bottle and a vacuum bottle containing tryptic soy broth demonstrated that growth was initially detected on the slant of the biphasic bottle or on a routine subculture of either broth in nearly 50% of instances. All organisms were isolated equally well in both bottles, with the excepti...

BACKGROUND Childhood iron deficiency is associated with behavioral and cognitive delays. Few studies have explored the relationship between prolonged bottle-feeding and iron-deficiency anemia among toddlers. OBJECTIVE To examine the association between prolonged bottle-feeding and iron deficiency in a nationally representative sample of children ages 1 to 3 years. DESIGN AND METHODS The Nat...
