Effects of an educational intervention on nurse practitioners' clinical breast examination techniques and ability to detect lumps in silicone breast models
… (CBE) technique and abilities to detect lumps in silicone breast models. Twenty-eight Louisiana nurse practitioners from varying specialties in two separate settings who agreed to participate were randomized into the control group or experimental group. Participants in the experimental …

Three-dimensional solitary waves in dispersive wave systems
… solitary waves, commonly referred to as 'lumps', have received far less attention than two-dimensional solitary waves in dispersive wave systems. Prior studies have focused in the long-wave limit, where lumps exist if the long-wave speed is a minimum of the phase speed and are described by …

Nonlinear dynamics of three-dimensional solitary waves
… localized) solitary waves, often referred to as "lumps"; these are nonlinear disturbances that propagate at speeds below cmin without change of shape owing to a perfect balance between the opposing effects of wave dispersion and nonlinear steepening. Moreover, Cmin is a critical forcing speed, as …

Advancements in nuclear waste assay
… used to observe the behaviour of gamma-rays in lumps of fissile material from plutonium over the mass range 0.001g to 350g, for a number of densities corresponding to Pu, PuO\(_2\) and PuF\(_3\). Established lump corrections have been analysed and have been found to produce large over- and …

Quantification of regional perfusion, shunt fraction and ventilation using positron emission tomography : a nonlinear tracer kinetics model
… for each defined region of interest (ROI). One lumps all aerated alveolar units, and the other lumps all atelectatic, edematous or fluid filled alveolar units with no gas content. Differential equations of the model were solved numerically and the parameters estimated using gradient-descent …

Punção aspirativa por agulha fina como meio de diagnóstico em cirurgia buco-maxilo-facial
… as well as in subcutaneous and submucosal lumps, all of them in the anatomical area of action of oral and maxillofacial surgery. The cytopathological results of the FNAB were compared with the histopathological results which, statistically showed indexes of precision of 95,66%, excluding …

Solution of Large Markov Models Using Lumping Techniques and Symbolic Data Structures
… developed a new compositional algorithm that lumps CTMCs represented as MDs. Unlike other compositional lumping algorithms, our algorithm does not require any knowledge of the modeling formalisms from which the MDs were generated. Our approach relies on local conditions, i.e., conditions on …

The analysis of late Stone Age hafting cements from the Cape Province, South Africa
… For the most part, the remains consist of odd lumps or traces on implements, but there are about a dozen fairly complete moulded pieces that allow some comment to be made as to the hafting strategy, and this technique is considered. To date, no success has been registered in identifying the …

The Letterkenny & Burtonport Extension Railway 1903-47: Its social context and environment
… other schoolchildren in searching for little lumps of coal along the permanent way. In later years, the same track bed became one of my favourite walks and set me wondering about the story behind so large a development at a time when few monuments of progress left much impression on our local …

Catalytic Cracking Of Hydrocarbons With Novel Metal Traps
… injections.;A kinetic model constituted by four lumps (gas oil, gasoline, light gases and coke), was found valuable to reproduce the experimental data of catalytic cracking reactions. The proposed mathematical model highlights the importance of separating coke and light gases as two different …

The role of Technetium-99m Sestamibi scintimammography to evaluate palpable breast lesions : a comparison with mammography and histological results
… was conducted on patients with clinical breast lumps with indeterminate mammographic lesions. Special emphasis was placed on lesion by lesion comparison of each breast lesion detected by clinical examination or scintimammography or both with the biopsy results of that particular lesion.

Determination and statistical evaluation of the effect of minerals and mineral associations in specific dense medium fractions on ash fusion temperature
… to sizes varying from tiny particles to lumps larger than 100mm. Channel burning and instability in the ash bed can occur as a result. It is therefore important to understand and anticipate the reactions of the mineral matter prior to feeding the coal into a gasifier. The principal aims …

Tachyon condensation in string field theory
… dimensions. We check that indeed the tensions of lumps of codimension one and two, coincide with the tensions of the respective D-branes within a precision of a few percent. We also give evidence for Sen's second conjecture; that in the nonperturbative tachyon vacuum all open string degrees of …

Effects of Variables on a Soaker-Stripper Reactor for Thermal Cracking of Deasphalted Oil
… network taking place. The model includes 5 lumps: residue (R), vacuum gas oil (VGO), distillates (D), naphtha (N) and gases (G). Thermal cracking of the residue followed first order kinetics with activation energies ranging from 172 to 250 kJ/kmol. Gases were found to be produced almost …

Soliton interactions and bound states
… 5 discusses Hopf solitons. Instead of being lumps, Hopf solitons actually resemble loops of string. Their charge is related to the string's knotting and twisting. In this chapter we include an extra mass term in the Skyrme-Faddeev theory; this gives solitons which are exponentially localised. …

Bacteriology of the reproductive tract of the peri parturient ewe and its relationship with fertility
… discharge (Type 3) was yellow/white with large lumps of pus and affected ewes were inappetant, visibly depressed with rectal temperatures in excess of 41.5C. Ewes with Type 2 and 3 discharges were found to produce fewer lambs per ewe than the flock average in the season following the discharge …

Very large eddy simulations of spatially evolving supersonic turbulent shear layers
… The high speed side convolutions of organized lumps of fluid are also decreased as M$\sb{\rm c}$ increases. However, the overall vortex size are only slightly modified, whereas the angular orientation is significantly modified. The merging process is very different as a function of M$\sb{\rm …
