Bulbs division

The main stem of the nitrometer widens into a bulb and then narrows to form a graduated tube. The usual graduation is of 8 ml. in o o2 ml. divisions. The graduations continue to the tap Tj at the top of the stem. Above Tj there is a small reservoir H to prevent splashing of the concentrated alkali when gas is expelled from the nitrometer and also to ensure that a small excess of potash is left as a liquid seal above the tap T ,. 

This straight-line proportioning holds good to close limits of accuracy. The horizontal divisions of dry bulb temperature are almost evenly spaced, so indicating sensible heat. The vertical intervals of moisture content indicate latent heat.

After ten minutes take the reading by holding the bulb behind the graduated tube with the meniscus in the bulb accurately in the same plane as the meniscus in the tube. Read the scale division which is in the same horizontal plane as the lower edge of the meniscus. Also note the temperature (thermometer in the part of the nitrometer above the stop-cock) and the barometric pressure. 

The bulbs containing the samples of the mixtiures are then weighed on an analytical balance with a sensitiveness of about 1.4 scale divisions per milligram, first when they contain the mixtures and then when they contain pure dry air. The percentage of the gas by volume in the mixture is...

Hairs That part of the hair that shows above the skin is called the shaft and the remainder is the root. The hair follicle in the dermis has a cluster of cells called the bulb, which is the site of the cell division responsible for hair formation. Nutrition for growth comes from the bloodstream the new cells are pushed upwards and as they die they become keratinized. Keratin... 

Thermometer Use a special total-immersion softening point thermometer,1 covering the range from 0° to 250° and graduated in 10 divisions. The bulb should be 15.9 0.8 mm in length and 6.35 0.4 mm in diameter.

Perhaps the best-loved of the springflowering bulbs, tulips have been admired and prized for centuries. Plant breeders have developed thousands of hybrids and cultivars from the more than 100 species in this genus. Divided into 15 divisions, based on bloom time, flower form, and parentage, tulips bear cup-shaped blossoms on 6"-24" tall flower stalks. Flowers come in all colors except true blue bicolors are common. Thick, 6"-8" long, straplike leaves surround flower stems.

All subdivisions of the ipsilateral AON project to both the ipsilateral and contralateral main olfactory bulbs except the external division (AON pars externa, AONpE) which projects only to the contralateral MOB (De Olmos et al. 1978) (Fig. 18A). The AON contains the largest number of neurons projecting to the bulb from any one source (Carson, 1984a). 

Candidate transmitters in AON and other olfactory cortical areas are summarized in Table 4. Aspartate has been proposed as a transmitter of AON neurons (mainly the dorsal and external divisions of AON) based on selective retrograde transport of H aspartate (Watanabe and Kawana, 1984 Fuller and Price, 1988). Fewer neurons in other subdivisions of AON contain aspartate, and no neurons in other known afferents to the bulb contain aspartate. There are a few met-enkephalin and somatostatinergic neurons in AON and some of these appear to project to the olfactory bulb (Davis et al. 1982). It appears that all neurons in AONpE contain the neuropeptide CRF (Shipley, in preparation). Besides the neurotransmitters/peptides discussed above, immunoreac-tive cells and fibers to calcium binding proteins have been described in AON. In this respect, calretinin immunoreactive fibers are found in the molecular layer of AON (Jacobowitz and Winsky, 1991), calbindin positive cells are found in all subdivisions of AON (Garcia-Ojeda et al. 1992 Celio, 1990) while parvalbumin positive cells are found in all subdivisions except for the medial one where the cells are quite sparse (Garcia-Ojeda et al. 1992 Celio, 1990).
