4981   Ectoparasitic infestations Ectoparasitic infestations
Jörg Heukelbach, Shelley F. Walton;Hermann Feldmeier    2005
Ectoparasitic infestations are highly prevalent in resourcepoor populations throughout the world and are associated with considerable morbidity. Reliable data on the epidemiology, immunology, and therapy of ectoparasitic infestations and on the biology of the parasites remain scarce. The control of parasitic skin diseases, such as scabies, pediculosis, tungiasis, myiasis, and cutaneous larva migrans in endemic areas remains a challenge. Using appropriate study designs, it...

4983   A similarity approach to predict landscape saturation in catchments A similarity approach to predict landscape saturation in catchments
   2002
An investigation into landscape saturation has been carded out analytically using similarity parameters derived from topographic, soil, and climatic attributes. Three parameters (an input index (q/Z)(L/KS), convergence ratio (CR), and profile factor (B)) define the extent of hillslope saturation. From these, a single dimensionless parameter has been derived to describe the occurrence of saturation in planar, concave, and convex profile hillslope shapes, and with parallel, convergent, and diverge...

4984   Involving the General Practitioner In Screening For Cervical Cancer Involving the General Practitioner In Screening For Cervical Cancer
Eleanor Bechtold and Norbert B. Reicher    2007
In the Leiden region, the cervical cancer screening programme for the age group 35–54 years shifted in 1989 from one in which the smears were taken by specially trained paramedical personnel in health centres to a programme where the general practitioner is the smear taker. Hence, it is possible to compare the results of the two types of screening to evaluate whether involvement of general practitioners leads to better uptake of screening. In the 6 year period evaluated in this paper, the ...

4985   A Geometric Theorem for Wireless Network Design Optimization A Geometric Theorem for Wireless Network Design Optimization
Massimo Franceschetti, Matthew Cook, Jehoshua Bruck    2002
Consider an infinite square grid ¢. How many discs of given radius £ , centered at the vertices of G, are required, in the worst case, to completely cover an arbitrary disc of radius £ placed on the plane? We show that this number is an integer in the set {3, 4, 5, 6} whose value depends on the ratio of £ to the grid spacing. This result can be applied at the very early design stage of a wireless cellular network to determine, under the recent International Telecommunication Union (ITU) prop...

4988   A comparison of risk assessment of single and combination manual handling tasks: 2. Discomfort, rating of perceived exertion and heart rate measures A comparison of risk assessment of single and combination manual handling tasks: 2. Discomfort, rating of perceived exertion and heart rate measures
   1997
Although many manual handling activities involve combinations of pull, lift, carry, lower and push, there are few reports of investigation of how to assess the risk in these combination tasks. Two strategies have been suggested in the literature for estimating the risk in a combination task based on the measures of the separate components of that task. The aim of the study was to compare the risks assessed in single manual handling tasks with those in combination tasks. Ratings of discomfort, ex...

4989   Accuracy of cervical smears in predicting the grades of cervical intraepithelial neoplasia Accuracy of cervical smears in predicting the grades of cervical intraepithelial neoplasia
G. Denise Zielinski, Peter J. F. Snijders, Lawrence Rozendaal, Feja J. Voorhorst, Arnold P. Runsink,    2002
This is a retrospective study carried out to assess the correlation between the cytology and histology of cervical intraepithelial neoplasia in 1325 women. A poor correlation between the cytologic and histologic diagnosis of the various grades of CIN was shown. Forty-one percent of smears with repeated borderline change and 50% of those predicting CIN1 showed a higher grade of CIN on histology. The overall apparent false negative rate of cervical smears for high grade CIN (CIN2 and CIN3) was 19%...

4991   Minimal, rigid foliations by curves on ℂℙ n Minimal, rigid foliations by curves on ℂℙ n
Frank Loray;Julio C. Rebelo    2003
We prove the existence of minimal and rigid singular holomorphic foliations by curves on the projective space ℂℙ n for every dimension n≥2 and every degree d≥2. Precisely, we construct a foliation ℱ which is induced by a homogeneous vector field of degree d, has a finite singular set and all the regular leaves are dense in the whole of ℂℙ n . Moreover, ℱ satisfies many additional propertie...

4993   Adaptive similarity metrics in case-based reasoning Adaptive similarity metrics in case-based reasoning
   2004
A similarity measure is a critical component in any case-based reasoning (CBR) system. It compares two cases with respect to their "features," with each feature using a separate "comparator."The results of the comparators are combined according to some rule to give an overall measure of the similarity between the given cases. Previous works have described a CBR framework that can easily be instantiated to provide a case-based reasoner for virtually any problem domain. This uses an "adaptive," or...

4994   Discrete distance and similarity measures for pattern candidate selection Discrete distance and similarity measures for pattern candidate selection
   1993
Within the area of pattern recognition research, there are many examples where pattern families are decomposed into or composed from a set of basic elements. Regardless of their decomposition/composition order, each pattern within such a family can be considered as a repeatable combination of pattern primitives, and a discrete distance space and a corresponding similarity measure to facilitate the pattern recognition process can be defined. The definitions and properties relevant to the above di...

4996   Sensitivity of the cytologic diagnosis of cervical condyloma in comparison with HPV-DNA hybridization studies Sensitivity of the cytologic diagnosis of cervical condyloma in comparison with HPV-DNA hybridization studies
Saibua B. Chichareon and Sathana T. Tocharoenvanich    2006
The cytologic diagnosis of cervical condyloma is based on criteria developed over the last 10 years. It has now become possible to document the presence of human papilloma virus (HPV) DNA directly in cervical swabs by the highly sensitive technique of DNA filter hybridization in situ. The purpose of this article is to evaluate critically the empirically established cytologic criteria of condyloma by comparing them with HPV-DNA hybridization studies in the same material. The results of this study...

4997   Design and Optimization of a Semi-Continuous Hot-Cold Extraction of Polyphenols from Grape Pomace Design and Optimization of a Semi-Continuous Hot-Cold Extraction of Polyphenols from Grape Pomace
Jeana K. Monrad, Keerthi Srinivas, Luke R. Howard, and Jerry W. King    2012
Grape pomace contains appreciable amounts of polyphenolic compounds such as anthocyanins and procyanidins which can be recovered for use as food supplements. The extraction of these polyphenols from the pomace is usually accomplished at slightly elevated temperatures, frequently employing hydroethanolic solvents. Due to governmental regulations and the cost involved in using ethanol as a solvent, as well as the loss in polyphenolics due to thermal degradation, improved extraction technique is de...

C. Robin Ganellin,*# Paul B. Bishop,# Ramesh B. Bambal,# Suzanne M. T. Chan,# James K. Law,# Benoit    2000
The cholecystokinin-8 (CCK-8)-inactivating peptidase is a serine peptidase which has been shown to be a membrane-bound isoform. of tripeptidyl peptidase II (EC 3.4.14.10). It cleaves the neurotransmitter CCK-8 sulfate at the Met?Gly bond to give Asp-Tyr(SO3H)-Met-OH + Gly-Trp-Met-Asp-Phe-NH2. In seeking a reversible inhibitor of this peptidase, the enzymatic binding subsites were characterized using a fluorimetric assay based on the hydrolysis of the artificial substrate Ala-Ala-Phe-amidomethylc...

5001   Surface renewal method for estimating sensible heat flux Surface renewal method for estimating sensible heat flux
   2010
For short canopies, latent energy flux may be estimated using a shortened surface energy balance from measurements of sensible and soil heat flux and the net irradiance at the surface. The surface renewal (SR) method for estimating sensible heat, latent energy, and other scalar fluxes has the advantage over other micrometeorological methods since the method requires only measurement of the scalar of interest at a point and the method may be applied close to the canopy surface, thereby reducing f...

   1979
A description is given of a combination of statistical and syntactical pattern recognition methods. The hierarchically structured recognition system consists of a conventional statistical classifier, a structural classifier which analyses the topological composition of the patterns, and two mixed stages which are based on search for maximum similarity between syntactically generated prototypes and patterns. The four stages work on different principles to avoid mistakes made in one stage by the o...

   2012
Context. The presence of stellar p-and g-modes allows us to test stellar structure models in great detail from the core to the envelope. As the driving mechanisms are not yet fully understood, the first important step is to provide clear evidence of these pulsation modes. Aims. Recent space missions have confirmed that the γ Doradus and the δ Scuti observational instability strips overlap and consequently that many stars may be hybrids. CoRoT ID 105733033 is an excellent example of t...

S. A. Orlov;K. V. Kholshevnikov    2012
Dust complexes in the Solar System are produced and maintained by different physical processes. However, one often requires equations of the same type to be studied and solved in order to mathematically describe these processes. We have analytically found earlier a shape of the complex formed when particles are ejected in a single-ejection event from a parent body orbiting a central body in a circular orbit. In the present paper, we consider a parent body moving ...
