Microinvasion is the smallest morphologically identifiable stage of invasion. Its presence and distinction from in situ carcinoma may have therapeutic implications, and clinical staging also requires the recognition of this phenomenon. Microinvasion is established on the basis of several morphological criteria, which may be difficult and not perfectly reproducible among pathologists. The aim of th
Two different mathematical methods of implementing a detailed kinetic soot model have been employed in this work. The theoretical description of the soot modeling employed in this work is divided into three parts. Initially a detailed kinetic soot model is described from a chemistry and physics perspective. The soot model is then elaborated into mathematical form, starting with the formulation of
This paper outlines possible strategies for evaluation of group relations conferences. Based on comparison of group relations and sensitivity training, the evaluations made of the latter are critically reviewed. Restriction to outcomes, means, variability measures, experimental paradigms and effect-without-process studies, instrumental views on learning and less developed conceptions of groups ham
We investigated possible motivations for sound symbolism in spatial demonstratives within 101 areally and genetically diverse languages. Six different predictions were formulated on the basis of factors such as (a) semiotic ground (iconic, indexical or combined), (b) speaker-centered, hearer-centered or both and (c) applicable to vowels, consonants or both. Each one of these six predictions result
AIMS: To assess the Edinburgh Postnatal Depression Scale (EPDS), a self-administered questionnaire created to screen for symptoms of postpartum depression in the community, from an epidemiological and ethical perspective. Screening, as the practice of investigating apparently healthy individuals to detect unrecognised disease or its precursors, has interpretation problems and is complicated by del
Some MIMO applications require antennas to be closely spaced, which result in mutual coupling among antennas and high spatial correlation for signals. In order to compensate for the performance degradation due to correlation and coupling, impedance matching networks may be used. Recently, it was shown that uncoupled matching networks could be optimized against a given performance metric with the c
The design and features of frequency-selective wallpaper created for attachment onto regular walls in order to filter out signals operating at 5 GHz while at the same time allowing the desired radio communication services to propagate through such walls are presented. An analysis of the characteristics of the radio channel evaluated in a typical indoor environment, when considering either regular
The cavitation phenomenon has today become a keystone for different areas of science and technology including various industrial processes and medicine. Recently increasing interest and much attention have been paid to study this phenomenon. The last two decades have witnessed the development of numerous devices for different important applications of considerable practical interest, and the rang
We have measured radiative lifetimes for selenium and tellurium resonance levels by using short pulse laser excitation in differentially heated resonance cells. We obtained tau(3S1 Se I) = 2.9(5) ns and tau(3S1 Te I) = 3.1(5) ns, which together with branching ratio values given by Ubelis and Berzinsh yield the absorption oscillator strength f(abs)(Se I, 196.0 nm) = 0.074(16) and f(abs)(Te I, 214.3

Magnetic resonance spectroscopy (MRS) is a non-invasive technique that can be used to detect and quantify multiple metabolites. This chapter will review some of the applications of MRS to the study of brain functions. Typically, (1)H-MRS can detect metabolites reflecting neuronal density and integrity, markers of energy metabolism or inflammation, as well as neurotransmitters. The complexity of th
For developing countries like Pakistan, in the absence and scarcity of trust-worthy solar radiation data, the need for an empirical model to predict global solar radiation seems inevitable. Various climatological parameters can be used to develop such models. In this study, linear regression models are developed to estimate the monthly average daily global radiation using cloudiness data for Karac
A delay in surgery due to laboratory abnormalities may increase mortality in patients with hip fracture. In order to optimize the logistics for urgent surgery in patients with hip fractures and anti-vitamin K treatment, individualized doses of a Prothrombin Concentrate were guided by a bedside whole blood prothrombin time test. Thirty patients with emergency hip fracture and preoperative anti-vit
PURPOSE: This study aimed to determine if there are any associations between serum levels of inflammatory markers and proliferative retinopathy (PDR) in type 1 diabetic patients. DESIGN: A cross-sectional design was utilized for this study. METHODS: One hundred twenty-eight type 1 diabetic patients underwent stereo fundus photography according to the Early Treatment Diabetic Retinopathy Study and
