Published: April 2019

Summary
Introduction Currently, one of the most important ecological issues is exposure to lead in environment, since it is a metal with evident toxic effects on human organism. Hard dental tissues are suitable structures for assessing long-term effects of exposure to toxic metals. The aim of this paper was to determine the concentration of lead in hard dental tissues of a rat with experimentally induced DM using SEM/EDS analysis, after 14 and 30 days of exposing animals to lead. Material and methods The study was conducted in rats of Wistar strains divided into the three groups. The first group consisted of 8 rats (128 molars and premolars of the upper and lower jaws) with experimentally induced DM, taking lead in the course of 14 days at the concentration of 1500 ppm; the second group included 8 rats (128 molars and premolars of the upper and lower jaws) taking lead in the course of 30 days at the concentration of 1500 ppm, while the third control group consisted of 5 healthy rats (80 molars and premolars of the upper and lower jaws). Experimental animals received lead-acetate every day at the concentration of 1500 ppm via water ad libitum. In these animals, diabetes mellitus was induced by Alloxan. The teeth samples were analysed using scanning electron microscopy (SEM). EDS analysis determined the mass fraction of lead and other elements in hard dental tissues. Results No lead was detected in a single tooth layer in the teeth of rats that received lead in drinking water in the course of 14 days. The average values of the mass fraction of lead, calcium, and phosphorus in enamel of teeth of rats receiving lead in the course of 30 days amounted to: lead 0.36%, calcium 15.48%, and phosphorus 10.62%. Lead was registered only in enamel. Conclusion Lead was detected in enamel only in rats receiving lead in the course of 30 days while it was not detected in teeth after the course of 14 days.

Summary
Introduction Calcium hydroxide (CH) is a medicament widely used in endodontic treatment due to its antibacterial, regenerative and biocompatible properties. Studies have shown that remaining CH on root canal walls and dentinal tubules can compromise sealer penetration, leading to its weak adhesion, volume change and, consequently, apical leakage.
The aim of this study was to compare the efficacy of four different techniques in removing calcium hydroxide from the root canal.
Material and Methods 32 extracted single-rooted teeth with one canal were used in this study. The canals were prepared using BioRaCe system (FKG Dentaire, Swiss) BR5 40/.04 with sodium hypochlorite irrigation after each instrument. Longitudinal grooves were formed on the proximal root surfaces. All canals (except negative control) were filled with aqueous CH suspension. After seven days of incubation, the teeth were allocated into the four groups (n=7), plus positive and negative control. Four techniques (systems) for CH removal were tested: conventional syringe irrigation (CSI), passive ultrasonic irrigation (PUI), XP-endo Finisher (FKG Dentaire, Swiss) and Canal Brush (Roeko, Coltene) with irrigation of 5 ml 2% NaOCl and 5 ml 10% citric acid. All the roots were then split into the two halves with chisel and observed under the stereomicroscope (Boeco, Germany) at magnification of 20x. The area with remaining CH on the root canal wall surface was then divided with the total root canal surface area (%). The obtained results were statistically processed using One-way ANOVA and Tukey post-hoc test (p<0.05).
Results The most efficient system was XP-endo Finisher with 91.33% of clean surface, followed by PUI 88.36%, Canal Brush 87.83%, and CSI with 66.92%.
Conclusion None of the systems completely removed the traces of the medicament from the root canal. For optimal clinical success, it is necessary to combine various systems with copious irrigation.

Published: April 2019

The aims of this study were to compare skipjack catch between FAD and free school fishing grounds and to describe the effect of the oceanographic factors on either skipjack tuna Fish Aggregating Device (FAD) or free school. We used a field survey method for collecting the skipjack catch and the fishing positions for both near FAD and free school areas. Remotely sensed satellite data of sea surface temperature (SST) and chlorophyll-a concentration (Chl-a) were also used to extract the oceanographic data corresponding with both the fishing locations. To find out the vital oceanographic factors, we examined the characteristics of the oceanographic variables and skipjack catch using t-test. Results indicated that the fishing operations of skipjack tuna at FAD tended to locate areas of relatively higher Chl-a than at free school locations. We also found that skipjack tuna catch was higher near the FAD than the other area, where the Chl-a was the most significant factor that affected the difference. This study suggests that the number of skipjack tuna FAD in the coastal waters of Bone Bay should be calculated accurately to ensure and support the tuna fishing management in that study area.

Man and Tree, Tumour and Burl: Complicating the Ecology of Illness in Early and Medieval China
Authors: Rothschild N. Harry 
Published: April 2019

Abstract

In early and medieval China, the natural world was understood, to an extent, to mirror human conduct and action. Because human events were often apprehended as poetic and metaphoric extensions of larger elemental processes, people in early and medieval China tended to see tumours as moral punishment meted out by all-seeing Heaven (
tian
) or karmic retribution in Buddhism. One would think, then, that burls, the grotesque, malformed intumescences bulging from trunks of trees would be relegated to the realm of the wicked and inauspicious. Surprisingly, this is not the case. Examining a series of passages involving burls in a wide range of early and medieval Chinese texts, this essay seeks to complicate this rather facile moral schema. The anomalous tumescent growth, whether on tree or man, did not simply betoken evil. At different times, the polysemous tumour-burl might augur future greatness, serve as a miraculous womb chamber, help one assume a twisted guise assumed to survive tumultuous times, impress with its remarkable aesthetic asymmetry, or merely provide a moment of levity.

Published: April 2019

The ballistic resistance of high-strength fabrics improves upon impregnation with Shear Thickening Fluids (STFs). The performance of such STF treated fabrics depends on the rheological properties of the STF which in turn are governed by the physicochemical properties of the STF. The present study utilizes rheological characterization of shear thickening silica-polyethylene glycol dispersions (of different material configurations in terms of packing fraction, particle size and continuous phase viscosity) to assess their performance and obtain the best STF material configuration for ballistic body armor applications based on the design criteria proposed herein. The ballistic performance assessment results showed that the STFs with high packing fractions which thicken discontinuously, are highly effective compared to the continuously shear thickening fluids. Furthermore, the use of smaller particle size dispersed phase in the STF formulation was determined to be economical. Also, the use of lower molecular weight dispersion medium was suggested as it allows for a broader working temperature range of the STF. Additionally, the technological issues associated with the development and the practical application of STF-Armor were addressed.

The aim of the study is to present the proposals of legal regulations presented by the European Commission in one of the fields of Area of Freedom, Security and Justice (JHA), i.e. within the framework of judicial cooperation in criminal matters. The European Commission’s proposals aim at strengthening of the rights of suspects/defendants in criminal proceedings in the EU. They consist of the right to a fair trial and include: strengthening of the presumption of innocence principle and the right to be present at the trial, special safeguards for children suspected or accused of a crime and the right to provisional legal aid for citizens suspected or accused of a crime. In the paper I analysed the most important provisions of the projects and showed that these proposals are intended to ensure the protection of fundamental rights within the JHA.
O tożsamości

The structure of identity forms the main point of discussion in this essay. The initial question “Who I am?” is divided into fragmentary questions: “Who I became?” and “Who I’m going to be?”, which are later contrasted with similar questions: “Who we are?” and “Who we all are?”. The analysis of relations between these questions and their sensible answers, reveals a factor of prescriptive, which is explained by appealing to some particular understanding of the word “good” manifesting in such feelings like pride, shame and sense of guilt. It leads to fragmentary definition: our identity consists of everything we are proud or ashamed of. There are some limitations of our freedom in ruling of identity in that meaning, however, and they are described further in this essay.

Published: April 2019

This paper is concerned with the numerical solution of the nonlinear Schrödinger (NLS) equation with Neumann boundary conditions by quintic B-spline Galerkin finite element method as the shape and weight functions over the finite domain. The Galerkin B-spline method is more efficient and simpler than the general Galerkin finite element method. For the Galerkin B-spline method, the Crank Nicolson and finite difference schemes are applied for nodal parameters and for time integration. Two numerical problems are discussed to demonstrate the accuracy and feasibility of the proposed method. The error norms L 2 , L ∞ and conservation laws I 1 , I 2 are calculated to check the accuracy and feasibility of the method. The results of the scheme are compared with previously obtained approximate solutions and are found to be in good agreement.
