Incomplete/unclear

It is unclear whether previously published fire risk analyses have adequately ircaicd dependent failures and systems interaetions. Examples of either experienced or postulated system interactions that have been missed include unrelated systems that share common locations and the attendant spatially related physical interactions arising from fire. Incomplete enumeration of causes of failure and cavalier assumptions of independence can lead to underestimation of accident l rci uencies by many orders of magnitude,... [Pg.200]

While MSDS s arc not required to be physically attached to a shipment, they must accompany or precede Oic shipment. When tlie manufacturer/supplicr fails to send an MSDS with a sliipmcnt labeled as a liazardous chemical, the employer must obtain one from Oie chemical manufacturer, importer, or distributor as soon as possible. Similarly, if the MSDS is incomplete or unclear, the employer should contact the manufacturer or importer to get clarification or obtain missing information. [Pg.303]

In the case of the higher temperature crystallization, as will be shown in Sect. 4, the theory of Doi et al. is applicable without doubt since the primary phase separation involves the transition from the isotropic to nematic phase, but in the case of the glass crystallization near Tg described above its applicability is unclear since the observed data may correspond to the secondary phase separation. However, if the secondary phase separation occurs, the primary phase separation must have proceeded prior to that. In a rapidly quenched glass even if the primary phase separation had already taken place, it would be still incomplete, so that it will re-start by heating. [Pg.203]

Very often the complete history of samples received into the laboratory may be unclear or incomplete. If it is not possible to find out detailed information about the background of a sample, then the sample should be treated with extra care. Where subsamples of a particular sample are sent to different parts of a laboratory, the labelling of each subsample should include any relevant safety warnings. [Pg.135]

Recently, the crystal structure of the related [Fe(abpt)2(N(CN)2)2] has been determined [8]. The species undergoes an incomplete transition (T1/2= approximately 86 K) with an indication of two steps, the origin of which is unclear. Below 60 K, about 37% of the Fe(II) ions remain high-spin. [Pg.150]

With only a few exceptions, the CdS is deposited from a standard ammo-nia/thioureabath at ca. 70°C, with variations in the concentrations of reactants, the use of temperature programming, and some variation in pH (using an ammonium chloride buffer). It is notable that, in spite of many attempts to substitute CdS by another CD material (driven by the desire for a environmentally friendlier material), CdS remains the best material to date for this purpose, both for CIS and CdTe cells. Other materials deposited by CD include various Zn(OH,S), Zn(OH,Se), and ln(OH,S) compounds and ln(OH)3. The three first materials appear to be incompletely sulphided or selenided hydroxides, and it is not clear whether they are a mixed or a single phase. Also, it is usually unclear whether oxide or hydroxide also occurs [although one XPS study of ln(OH,S) has demonstrated the absence of either ln(OH)3 or ln2S3 in the film]. While some of these buffer layers approach CdS in terms of cell efficiency, they are invariably inferior. [Pg.84]

From the painted walls of tombs, temples and other structures which have been protected from exposure to weather, and from the decorated surfaces of pottery, chemical analysis often is able to give us knowledge of the materials used for such purposes. Such data also serve at times to assist in the interpretation of the often unclear or incomplete descriptions given by extant ancient writers. [Pg.13]

Whether or not dietary quercetin and other flavonols can accumulate in internal organs is controversial. It is unclear if they accumulate in the human body, but dietary quercetin was found to be distributed in each organ in experimental animals [de Boer et al., 2005]. In rats fed 0.1% quercetin for 11 weeks, the highest accumulation was in the lungs. Low amounts of quercetin metabolites were detected in the brain. This indicates that quercetin metabolites can access the central nervous system by passing the blood-brain barrier, although the mechanism of this passage is incompletely understood. [Pg.191]

The comparison of the stability conditions of wetting films with the coefficients and pressure of spreading indicates that even when two spreading coefficients are used (s and se) or (sand n°B/A) the information about stability proves to be incomplete [531], For instance, at s > 0, but 0 < se < 0 there is a range of thicknesses in which the films are unstable but the position of the range of thicknesses where this instability is expressed remain unclear. [Pg.317]
