A patient with hematochezia and a false negative Meckel's scan is presented. A Meckel's diverticulum was subsequently diagnosed on barium small bowel follow-through. Meckel's diverticulum is discussed with emphasis on the relationship of barium and radionuclide studies.

Nursing behavior is notoriously difficult to study in arboreal primates, particularly when offspring suckle inconspicuously in nests. Orangutans have the most prolonged nursing period of any mammal, with the cessation of suckling (weaning) estimated to occur at 6 to 8 years of age in the wild. Milk consumption is hypothesized to be relatively constant over this period, but direct evidence is li...

We present a first-principles study of the series of multiferroic barium fluorides with the composition BaMF4, where M is Mn, Fe, Co, or Ni. We discuss trends in the structural, electronic, and magnetic properties, and we show that the ferroelectricity in these systems results from the freezing in of a single unstable polar phonon mode. In contrast to the case of the standard perovskite ferroel...

OBJECTIVES To report an unusual presentation of a giant sigmoid diverticulum in the colon. CLINICAL PRESENTATION AND INTERVENTION The patient presented with an abdominal mass, altered bowel habits, and increasing weight. The provisional diagnosis was made by barium enema and CT scan. The patient underwent laparotomy, revealing a perforated giant sigmoid diverticulum that was excised using Har...

A new protocol for measuring the branching fraction of hydrogenic atoms with only statistically limited uncertainty is proposed and demonstrated for the decay of the P3/2 level of the barium ion, with precision below 0.5%. Heavy hydrogenic atoms like the barium ion are test beds for fundamental physics such as atomic parity violation and they also hold the key to understanding nucleo-synthesis ...

Complications of barium sulphate studies abound in the literature but there are very few recorded instances of large bowel obstruction due to inspissated barium and faeces forming a 'barolith'. A patient who suffered this complication is reported.

The bending-induced polarization of barium titanate single crystals has been measured with an aim to elucidate the origin of the large difference between theoretically predicted and experimentally measured flexoelectricity in this material. The results indicate that part of the difference is due to polar regions (short-range order) that exist above T(C) and up to T*≈200-225 °C. Above T*, howeve...

a semi-batch crystallization system is used to determine growth kinetics and morphology of barium carbonate crystals, under a constant ph value and constant temperature in the various relative supersaturations. results show that crystal growth rate satisfies a first-order kinetic expression at high relative supersaturation, while at relative supersaturation values lower than 3,  the kinetic exp...
