We present the results of a 1.3mm continuum study of 59 Bok globules located north of−30◦ declination. The catalogue of Clemens & Barvainis (1988) served as a search list for the target objects investigated here. Based on the analysis of the IRAS point source colour-colour diagram, four distinct groups of globules are distinguished. It is shown that indeed each of these groups has distinctive p...

Introduction: Recent work has shown that sub-micron car-bonaceous spheres (" nanoglobules ") constitute a microstructur-ally distinct, ubiquitous form of extraterrestrial organic carbon. Nanoglobules have been reported to occur in the insoluble organic matter (IOM) of carbonaceous chondrites, in the matrices of primitive chondrites, in interplanetary dust particles and in Wild-2 samples [1-4]. ...

Using the Submillimeter Common-User Bolometer Array (SCUBA) at the James Clerk Maxwell Telescope (JCMT), we obtained submillimeter polarization maps of the Bok globules B 335, CB 230, and CB 244 at 850 μm. We find strongly aligned polarization vectors in the case of B 335 and CB 230, indicating a strong coupling of the magnetic field to the dust grains. Based on the distribution of the orientat...

The changes in milk fat globules and fat globule surface proteins during concentration of whole milk using a pilot-scale multiple-effect evaporator were examined. The effects of heat treatment of milk at 95 degrees C for 20 s, prior to evaporation, on fat globule size and the milk fat globule membrane (MFGM) proteins were also determined. In both non-preheated and preheated whole milk, the size...

A new type of globular particle, the 'insoluble yolk globule', was isolated from the egg yolk of three avian species (hen, duck, and emu) by centrifugation or gel-filtration chromatography. These globules are stable in NaCl and urea solutions at concentrations that dissolve or disrupt other constituents of yolk, The isolated globules are about 1% of the dry yolk of hen's and duck's eggs but abo...

Separation of milk fat in small globules (SG) (diameter lower than 2 μm) and in large globules (LG) (diameter higher than 2 μm) was realized by a patented process using special ceramic microfiltration membranes. Transformations in drinking milks, yoghourts, sour cream, camembert, Swiss cheese and butters were realized from milks of which the fat content was adjusted either by reference cream or...

Dermoscopy disclosed a sharply demarcated lesion corresponding to the jelly-sign (red arrows). Additionally, multiple small and loosely arranged brown globules (blue circles) resembling the so-called dermoscopic “concentric structures,” were seen (Figure 2). A punch biopsy of the lesion was performed. Histopathological examination revealed multiple heavily pigmented intra-epidermal nests of bas...

The globules in goblet cells in the epithelium of the dog ileum show a moderate contrast between the light and dark types. The globules appear to arise from the Golgi apparatus. Membranes encapsulate all of the globules in the earlier stages but a part of the mucosubstance undergoes a dispersion or, in some cases, possibly a fusion before their discharge into the intestinal lumen. There is litt...

The microstructure of calcium-silicate-hydrate (C-S-H) gel, a major hydrated phase of Ordinary Portland Cement, with and without polycarboxylic ether (PCE) additives is investigated by combined analyses of small-angle X-ray scattering (SAXS) and small-angle neutron scattering (SANS) data. The results show that these comb-shaped polymers tend to increase the size of the disk-like globules but ha...
