Forming of roll

In the present study, bread in the form of rolls was prepared from whole grain flour (100% extraction rate) with a zinc content of 22 mg/kg and from white wheat flour of about 72% extraction rate, where the zinc content was 7 mg/kg. The water added to the dough, contained an amount of almost carrier free isotope solution, corresponding to 0.25y/ Ci of Zn for each roll. The isotope solution was made by diluting a stock solution of 65 Zn CI2 in 0.1 M HCl (0.1 to 0.5 Ci/g Zn, Radiochemical centre, Amersham, England) with physiological saline to a final radioactivity of Ci/ml. [Pg.214]

Absorbent cotton is available in different qualities varying with the length and diameter of the cotton staple. It is available in the form of rolls and balls and is used for cleansing and swabbing wounds, preoperative skin preparation, and the application of topical medicaments to the skin. [Pg.1025]

Resistance heating usually involves the highest electricity costs, and may require circulating fans to assure the temperature uniformity achievable by the flow motion of the products of combustion (poc) in a fuel-fired furnace. Silicon control rectifiers have made input modulation more economical with resistance heating. Various materials are used for electric furnace resistors. Most are of a nickel-chromium alloy, in the form of rolled strip or wire, or of cast zig-zag grids (mostly for convection). Other... [Pg.17]

In the proposed design the processing plant is a concrete-lined pit which has a capacity of about 100,000 gallons. It is located outdoors and the top of the pit is formed of rolling concrete shielding blocks. The plant is operated dry but when maintenance is necessary the cells can be flooded with water. We have developed tools for the simple maintenance jobs which we know will be necessary and, in general, are very enthusiastic about the simplicity of design which is possible because of the maintenance philosophy. [Pg.414]

In both the cases considered, an optical contrast of the patterns observed in isotropic liquids is very small. Certainly, the anisotropy of Uquid crystals brings new features in. For instance, the anisotropy of (helectric or diamagnetic susceptibility causes the Fredericks transition in nematics and wave like instabilities in cholesterics (see next Section), and the flexoelectric polarizaticm results in the field-controllable domain patterns. In turn, the anisotropy of electric conductivity is responsible for instability in the form of rolls to be discussed below. All these instabilities are not observed in the isotropic liquids and have an electric field threshold controlled by the corresponding parameters of anisotropy. In addition, due to the optical anisotropy, the contrast of the patterns that are driven by isotropic mechanisms , i.e. only indirectly dependent on anisotropy parameters, increases dramatically. Thanks to this, one can easily study specific features and mechanisms of different instability modes, both isotropic and anisotropic. The characteristic pattern formation is a special branch of physics dealing with a nonlinear response of dissipative media to external fields, and liquid crystals are suitable model objects for investigation of the relevant phenomena [39]. [Pg.335]

Borneo Tallow.—The kernels of several species of Hopea (or Dipterocarpus), which flourish in the Malayan Archipelago, yield a fat known locally as Tangawang fat. This fat is moulded (by means of bamboo canes) into the form of rolls about 3 inches thick, and exported to Europe as Borneo Tallow. [Pg.32]

Although zinc can be used in the form of rolled sheet and strip, its widest use in building is for protective plating. When exposed to weather, zinc on the surface of galvanized steel develops a passive film that protects the underlying zinc and, thus, the steel. When the surface is scratched or scored, the anodic zinc corrodes, protecting the cathodic steel from attack. [Pg.825]

Coir nonwoven fabric mats made in the form of rolls Ailing them with peat moss/coir pith composite are used for biorolls. Rapid root growth is observed using these biorolls. The natural product combination will support the development of plant. [Pg.379]

On the other hand, excessively high Froude numbers (Fr > 5) are associated with steep slopes. Steep slope instability was discussed by Niepelt and Locher (1989). Slug flow is reported at high Froude numbers, causing working instability in the form of roll waves. [Pg.320]

Roll-call - in addition to a sweep of the premises it is often the case that some form of roll-call will be taken at the fire assembly point. The level and nature of the roll-call will be determined by the fire risk assessment and be dependent upon factors such as ... [Pg.262]

The discovery of carbon nanotubes (CNTs) is generally attributed to Sumio lijima who in 1991 discovered tubular forms of rolled-up graphene sheets (sheets of hexagonal sp -bonded C atoms) with bucky ball-like end caps. lijima s paper brought definitive news of such structures to the western world where it set off a flurry of research activity. [Pg.104]

The single-stranded DNA genomes of certain small E. coli viruses (such as M13 and ( X174) are replicated in the form of rolling circles in which unidirectional synthesis of one (virus genome) strand occurs by continuous displacement from the template (complementary strand Fig. 4A). The initial duplex DNA (called the repUcative... [Pg.125]

The literature on corrosion testing of aluminum alloys in seawater is extensive. Summaries of information are provided in Ref 28 and 29, and in most of the Selected References. Table 8 lists results of 10 year immersion testing of various alloys in the form of rolled plate exposed in three locations. Similar data for extruded products of several 6xxx alloys and one 5xxc alloy are given in Table 9. Direct cotrparison of the data in Tables 8 and 9 is provided in Table 10, in which corrosion is expressed in terms of average weight loss, and in Fig. 10, which illustrates the decel-... [Pg.147]
