Anomalous heat, attributed to Low-energy Nuclear Reactions (LENRs), is obtained by pressurizing metal alloy nanoparticles with deuterium gas. The reactions are enhanced by creation of ultra-high density deuterium clusters in the nanoparticles. Experiments comparing various nanoparticles and plans for a proof-of-princi…
This paper discusses the deformation and elemental distribution of different palladium film surfaces after loading and unloading many times deuterium gas in the system.
On allowing Me4NO2CSO3H (in water) to react with SnCl4 (in ethanol) the studied complex is obtained. The suggested structure is discrete, the anion behaving as a polydentate and chelating ligand, the environment around tin being octahedral.
In the present study, the microstructure and mechanical properties of cast Fe-10Cr-1.5B (FCB) alloy after different heat treatments were studied. The results showed that the as-cast microstructure of FCB alloy consists of ?Fe, M(M=Cr, Fe, Mn)2(B, C) and M(M=Cr, Fe, Mn)7(C, B)3 type borocarbides, and small amounts of p…
Using thermal insulation in negative temperature acts to reduce heat flow to the cooled space or to objects that have a temperature below ambient temperature. To achieve economic operation of the space to be cooled insulation thickness and quality is an important factor. In this article we want to compare three produc…

The corrosion inhibition of mild steel by Yttrium salt Y(NO3)3 6H2O at different concentrations in 0.5 N NaCl, has been carried out by potentiodynamic tests and electrochemical impedance spectroscopy (EIS).In ions Y+3 presence, the ions OH- formation at the interface (electrode / electrolyte ) by water and oxygen redu…
Modeling singular solutions of the elasticity theory problems, which are determined by geometric factor - bird's mouth of the edge, make it necessary to analyze the solutions with some peculiarity, which are obtained experimentally with the help of photoelasticity method. In this article the peculiar stress-strain sta…
We have already considered an introduction of reinforcements in the variational-difference method (VDM) of shells analysis with complex shape. At the moment only ribbed shells of revolution and shallow shells can be calculated with the help of developed analytical and finite-difference methods. Ribbed shells of arbitr…
The samples of fiber reinforced concrete with different fiber concentration, types of fiber, class of concrete were tested. The values of the critical stress intensity factors were determined as well as the strength characteristics of fiber-reinforced concrete of various compositions. Tests were carried out by bending…
Three-dimensional (3D) textile structures with better delamination resistance and damage impact tolerance to be applied in composites for structural components is one of the main goals of the aeronautical industry. Textile Research Centre in Canet de Mar has been working since 2008 in this field. Our staff has been de…
When a diver is selected to perform a deep diving course, he has to pass a medical test and isn’t affected by the HPNS (High Pressure Nervous Syndrome). When a diver is selected to perform a deep diving course, he has to pass an evaluation stage in order to prove his ability to tolerate the compression speed accompani…
In this paper is about of the Hays-Kendall theoretical model of testing the microhardness of the composites materials of NiP/SiC type. We used an indenter to establish the microhardness of the composite and different types of loads. The microhardness can be interpreted using a theoretical model Hays-Kendall and the Ki…
În lucrare s-a urmărit scopul de a obţine compuşi macromoleculari cu proprietăţi utile pentru confecţionarea obiectelor de uz spitalicesc. A fost realizată sinteza unor polimeri ce conţin grupe funcţionale active şi a fost efectuată legarea lor chimică (grefarea) cu preparate antimicrobiene (penicilină). Ca material d…
I will conclude QCD Evolution Workshop. I will also mention the future venue and briefly discuss results and goals of our workshop.
Medical products play an important role in our society. Textile structures offer a wide variety of products which can be used in a wide variety of medical applications. When treating a deep wound, it needs to be sewed with some yarns in order to stick both sides in the wound. It requires the yarn to be in contact with…
The dyeing of knitted fabrics made from 100 % cellulose using on-line procedure vinyl sulfonic reactive dye, with or without ultrasound energy, is carried out in this paper. The impact of temperature has been observed. The dye exhaustion is monitored using the method of absorption spectrophotometry, and the quality co…
Multilayer systems with metamaterials are studied. A system comprising parallel alternated layers filled with metamaterial and vacuum is considered. The problem of obtaining expressions for electric part of the Green’s function is raised for the NIM situation. A NIM situation is a case when electric and magnetic perme…
This paper has been withdrawn at the author's request. Complementary tests have been performed and the paper has been revised both in discussion and in presented data considering the new results. The revised version should be considered as a new publication and all the authors agree about the decision.
