This paper presents a generic Trust Negotiation framework for Web services, based on the WS-Trust standard. It allows users to create trust incrementally, by disclosing credentials step by step. This way, services and resources can be shared in an open environment, and access can be realized on the basis of peer-to-peer trust relationships. The paper also describes a practical implementation of...

the molecular weight distribution of 4 commercial isotactic polypropylene (ipp) samples was estimated using rheological data. the dynamic moduli data, obtained from rheological measurements in linear viscoelastic region was used for calculation of relaxation time spectrum, h(τ) and then shear relaxation modulus, g(t). finally, applying thimm kernel function and relaxation modulus data in genera...

We discuss scenarios with wrong-sign (WS) Yukawa couplings for the discovered Higgs boson in Yukawa-aligned two doublet model. In WS scenario, down-type quarks and/or charged leptons have an opposite sign as compared to those of standard model, which can be consistent current flavour data and signal strengths. The phenomenology additional bosons such a scenario significantly different from that...

Twenty years have passed since Tomonaga made his important contribution to quantum electrodynamics. Quantum electrodynamics, although incomplete, is a triumph of quantum field theory applied to the electromagnetic interaction and has served as a model for dealing with the other particle interactions as well. The conspicuous lack of success in the domain of non-electromagnetic interactions has l...

Background. Execution of fitness testing in physical education classes is influenced by students’ motivation. Therefore, addressing new testing approaches seems necessary to more accurately measure student performance. Objectives. This study presents changes in fitness performance after applying a physical fitness tests battery (without external stimuli - WS) and with external stimuli (verbal ...

The use of mulching in agriculture suppresses the weeds around crop plants, enhances nutrients status soil, controls soil structure and temperature, reduces water evaporation. Excessive low-density polyethylene mulches is contributing to accumulation high amounts plastic wastes, an environmental problem for agricultural ecosystems. Fragments from such wastes can be found soils, resources, organ...

Wolfram syndrome (WS) is a rare autosomal recessive neurodegenerative disease with variable symptoms, including neuropsychiatric manifestations. A 26-year-old man was reported with classic symptoms of WS and repetitive psychiatric hospitalizations and at least 16 suicidal attempts. The genetic study demonstrated a novel homozygous stop-codon mutation on the WFS1 gene. This special type of mutat...
