Previous studies have been made of the pat terns of free or easily extractable ninhydrin-reactive constituents in a variety of animal tumors (7, 13-17). Although each normal tissue in a par ticular species has been found to have a distribu tion of these substances characteristic for that tissue, all of the tumors examined have shown a similar pattern. Relatively low levels of free or easily ext...

The fine structure of the human wart virus is compared with that of the Shope rabbit papilloma virus. The distribu tion of the viral antigens within the human wart, as determined by immunofluorescence, is described and compared with the distribution of the viral antigens in the rabbit papilloma. The distribution of viral particles in the two lesions, as determined by electron microscopy, is als...

Yangjiang coastal waters provide vital spawning grounds, feeding and nursery areas for many commercial fish species. It is important to understand the spatial distribution of management, development, protection fishery resources. In this study, an acoustic survey was conducted from 29 July 5 June 2021. Meanwhile, remote sensing data were collected, including sea surface temperature (SST), chlor...

A mean residence time (MRT) is an important pharmacokinetic parameter. To the author's knowledge, however, a physiologically based structure of MRT (thereafter MRT structure) has not been published so far. Primarily this is because MRT structures cannot be identified by traditional pharmacokinetic methods used for the determination of MRT. Therefore, tools from the theory of linear dynamic syst...

Intercomparisons of hillslopes and catchments in different hydrogeomorphic settings are rare. Those comparison studies that have been completed have focused largely on bulk outflow and chemistry. Here, we present a new functional intercomparison of two well studied hillslopes: one in New Zealand at Maimai and one in Japan at Fudoji. Slope angle, slope length, soil depth, climate and vegetation ...

The goal of the paper is to investigate impact tire tread depth on road accident risk and develop an rate prediction model. state 4288 vehicle tires using gauge was inspected processed statistically. most worn from each registered for further analy-sis. Based collected data, a statistical model insurance company fleet had been developed. conformity gamma distribu-tion data verified upon applyin...

A new algorithm is presented for the detection and segmentation of multiple periodic motions in image sequences A periodicity measure which provides an accurate quantitative measure of sig nal periodicity in the form of temporal harmonic energy ratio is proposed The periodicity tem plates which incorporate the segmented region with the associated periodicity energy distribu tion and motion fund...

This article presents the main ethical challenges faced by social work professionals in Spain during "first wave" of COVID-19 2020. The pandemic had a serious impact not only on health sector, but also field work. During this time, workers to address questions regarding issues such as confidentiality breaches, how fairly distribute available resources, lack personal contact and emotional connec...

Many crystalline materials show chemical short range order and relaxation of neighboring atoms. Local structural information can be obtained by analyzing the atomic pair distribution function (PDF) obtained from powder diffraction data. In this paper, we present the successful extraction of chemical short range order parameters from the x-ray PDF of a quenched Cu 3 Au sample.

A method is presented that uses the well-understood O2/Ax ion-molecule reaction system to determine the effective ion source residence time of a chemical ionization source. The process consists of: (1) defining the kinetic system in terms of reactions, reaction rates, and ionization cross sections; (2) solving the differential equations that describe the time evolu-tion of the kinetic system, a...
