OBJECTIVE To examine the effect of 6 months of high- or low-intensity resistance exercise on aerobic capacity and treadmill time to exhaustion in adults aged 60 to 83 years. METHODS Sixty-two men and women completed the study protocol. Subjects were matched for strength and randomly assigned to a control (n = 16), low-intensity exercise (LEX, n = 24), or high-intensity exercise (HEX, n = 22) ...

BACKGROUND This study examined a programme of pre-conditioning exercise with subsequent high intensity interval training (HIIT) on blood pressure, echocardiography, cardiac strain mechanics and maximal metabolic (MET) capacity in sedentary (SED) aging men compared with age matched masters athletes (LEX). METHODS Using a STROBE compliant observational design, 39 aging male participants (SED; n...

We can break symmetry by eliminating solutions within each symmetry class. For instance, the Lex-Leader method eliminates all but the smallest solution in the lexicographical ordering. Unfortunately, the Lex-Leader method is intractable in general. We prove that, under modest assumptions, we cannot reduce the worst case complexity of breaking symmetry by using other orderings on solutions. We a...

Traditionally, the oxygen content of blood has been determined by the Van Slyke vacuum extraction and manometric method. This method, although offering good accuracy and precision, suffers from several disadvantages. The operator needs extensive training and practice, the apparatus needs careful handling and cleaning, and the reagents must be made frequently and degassed. An instrument (“Lex-02...

Objectives. To evaluate the polishing procedures effect on color stability and surface roughness of composite resins. Methods. Specimens were distributed into 6 groups: G1: Filtek Supreme XT + PoGo; G2: Filtek Supreme XT + Sof-Lex; G3: Filtek Supreme XT + no polishing; G4: Amelogen + PoGo; G5: Amelogen + Sof-Lex.; G6: Amelogen + no polishing. Initial color values were evaluated using the CIELab...

The mechanism of expression of a series of glycolipid antigens carrying the Lex determinant structure, Gal beta 1----4[Fuc alpha 1----3]GlcNAc beta 1----, and characterized by oncofetal expression in fetal colon and colonic adenocarcinomas has been studied in human fetal and adult proximal colon tissue. Results presented from TLC immunostain analysis of neutral glycolipids isolated from normal ...

Given a string α = 10γ in a binary language L, the bubble lower bound is the smallest non-negative integer j such that 1s−10t−j10jγ ∈ L. We present an efficient oracle, which is a function that returns the bubble lower bound, for a number of fixed-density languages including: k-ary Dyck words, connected unit interval graphs, linear-extensions ofB-posets, those lexicographically larger than ω, t...

H.264/AVC is the newest video coding standard. There are many new features in it which can be easily used for video encryption. In this paper, we propose a new scheme to do video encryption for H.264/AVC video compression standard. We define Unequal Secure Encryption (USE) as an approach that applies different encryption schemes (with different security strength) to different parts of compresse...

Lex Salica was made at the end of the 5th century and it governed the Salian Franks. In those times, there were other so-called leges barbarorum, which together formed (as well as Lex Salica) important source of early feudal law in Western Europe. Lex Salica included common law of the Salian Franks which was adopted by the government and therefore had the effect of the law. Most provisions incl...

The European Regulation 2003/10/EC, voted by the European Parliament in 2003, is implemented in most of the countries of the European Community since 2006. This regulation defines different actions to be taken by the employer when the employees are submitted to continuous or impulse noise which exceeds the lower or upper exposure action value. It also defines maximum exposure levels to which em...
