Every archaeological excavation must deal with a vast number of ceramic fragments. The documentation, administration and scientific processing of these fragments represent a temporal, personnel, and financial problem. We are developing an automated classification and reconstruction system for archaeological fragments. The goal is to relate different fragments belonging to the same vessel based ...

The fraction collection of DNA fragments for studying gene expression, suffered from technical difficulties, including those related to the accurate capture of fast moving targets and pure collection under conditions of insufficient separation. We introduces a new concept of simultaneous space sampling for capturing targets in complicated situation, like overlapping fragments. Ten parallel extr...

In this paper we operated ant collections in three inland Atlantic forest fragments and in the neighboring Edmundo Navarro de Andrade State Forest (FEENA), an Eucalyptus plantation located in Rio Claro, interior of São Paulo State. We show that the ant communities of the native forest fragments are more similar among themselves than to the ant community of FEENA. Thus we evidence that, in addit...

The complex fragments (or intermediate mass fragments) observed in the low-energy 58Ni+58Ni→116Ba∗ reaction, are studied within the dynamical cluster decay model for s-wave with the use of the temperature-dependent liquid drop, Coulomb and proximity energies. The important result is that, due to the temperature effects in liquid drop energy, the explicit preference for α-like fragments is washe...

The aim of this in vitro study was to examine the secretion activity (progesterone, 17beta-estradiol and insulin-like growth factor-I) of rat ovarian fragments after molybdenum (Mo) addition. Rat ovarian fragments were incubated with ammonium molybdate (NH(4))(6)Mo(7)O(24).4H(2)O at the doses 90, 170, 330 and 500 microg.ml(-1) for 24 h and compared with control group without Mo addition. Releas...

Three-dimensionally preserved fragments of the enigmatic organism Sandvikina, previously reported from Silurian Ireland, Scotland and Scandinavia, were recovered original Irish material that had revealed problematic in thin sections. The new specimens derive conodont residue document silicified sectors distal part skeleton. Adifferent pattern characterizes outer inner walls, with an external ne...

OBJECTIVE Free fragments of synovium have occasionally been seen in synovial fluid but have not been studied systematically. We wished to establish a method for the reliable detection of these fragments in joint and bursa effusions and begin to characterize them by histochemical and immunohistochemical methods. METHODS Cell smears, wet drop preparations and cytospins were prepared from 39 con...

First of all we segment, label and reconstruct the relevant fragments of the fractured bone in the preoperative computed tomography. After that, we use a voting mechanism to compute bone shaft axis and circumference of the long bone fragments, and separate the fractured surface. This Houghlike method is based on the fact, that most of the surface normals of the superficies surface (periosteum) ...

We analyzed recent experimental data on the disassembly of $^{28}$Si into 7$\alpha$ in terms a hybrid $\alpha$-cluster model. calculated probability breaking several $\alpha$-like fragments for high $l$-spin values identical and non-identical spin zero nuclei. Resonant energies were found each $l$-value compared to other theoretical models. Toroidal-like structures revealed coordinate momentum ...

The description of chemical structures as a collection of connected molecular fragments is a basic requirement of coarse grained simulation methods like molecular fragment dynamics. These methods use molecular fragments as their basic interacting entities ("atoms”) and allow the modelling and investigation of very large chemical systems. Therefore a molecular fragments chemoinformatics is in ne...
