Settling
Settling is a collection of poems that interrogates the location of self in the physical, personal and metaphorical worls. There are thirty poems that explore different aspects of 'settling' from a woman's perspective.

Wax Anti-Settling Additives
Wax anti-settling additives (WASA) are used to mitigate against the problems caused by the settling of n-alkane wax crystals, which crystallise from petroleum diesel. This can result in the blocking of fuel filters and hence vehicle failure. However, the mode of action for such additives is not …

Studies on hindered settling and related topics
The stability of some suspensions, and the settling-out of others,both natural and man-n~de, are of widespread occurrence andimportance. Nonetheless, in spite of the efforts of numerousworkers, published theories and mathematical representations ofsedimentation behaviour are relatively rudimentary. …

Active and Passive Settling By Marine Benthic Nematodes
… the settlement of marine benthic nematodes. The settling rates of three estuarine benthic nematode taxa were examined in a linear flume using two treatments defined by the type of sediment bed placed in the flume. One treatment bed contained sediments rendered "unattractive" by boiling. The other …

Settling and sedimentation behavior of fine-grained materials
… an observed phenomenon that often occurs during settling and sedimentation processes of finer materials. However, it has been regarded as a minor factor affecting settling process, e.g. settling velocity or consolidation rate. In this study, settling behaviors of talcs, kaolins and attapulgite …

Accelerated settling of particulate matter by ’marine snow’ aggregates
… and Black Sea) provide strong evidence for rapid settling of marine particles by aggregates. Particle water column residence times were determined by measuring the time lag between the interception of a flux event in a shallow trap and the interception of the same event in a deeper trap at the …

Settling for Less out of Fear of Being Single
… hypothesis that fear of being single predicts settling for less in ongoing relationships, showing that fear of being single predicted greater dependence on unsatisfying relationships. Studies 3A and 3B explored the predictive ability of fear of being single for self-reported dating standards. …

Primary sedimentation tank model with characterized settling velocity groups
… the separation of solids and liquid in primary settling tanks (PSTs) of wastewater treatment systems. These physical processes are described by various settling conditions such as discrete and flocculent settling, along with other phenomena such as flocculation, coagulation, ammonification or …

Mathematical simulation of dynamic behaviour of secondary settling tanks
… theoretical and practical aspects of secondary settling tank developments closer together. This was achieved firstly, by evaluating and developing empirical relationships from which the flux theory constants may be derived from simpler sludge settleability measures; and secondly, by developing a …

Finite element analysis of flows in secondary settling tanks
Secondary settling tanks (SSTs) form a crucial part of wastewater treatment plants. Besides having to produce the separation of suspended solids and clarified effluent the secondary settling tank is used to concentrate and recycle the settled sludge to the biological reactor. The efficiency of the …

Temporal biomass density and filamentous bacteria effects on secondary settling
… years, the majority of the research in secondary settling problems has focused on the role of filamentous bacteria, and also factors such as floc size and shape. The effects of variable biomass density on settleability of biosolids produced in full scale activated sludge wastewater treatment …

On the structure of flow in an inclined settling column
… was to gain a clearer understanding of the settling mechanism through observation of the flow fields within a particle-free fluid layer which exists at the upper face of the bulk suspension and within the bulk suspension itself. Experimental investigations were carried out using glass beads …

An Appraisal of Third-Party Mechanisms in Settling International Environmental Disputes
… of the existing third-party mechanisms in settling such disputes. This thesis attempts to find suitable means by examining the nature of each dispute settlement mechanism and making an evaluation in order to find out how each mechanism can provide processes or procedures that correspond to …
