Objective To explore the effects of Prunella vulgaris L （PVL） on the growth of hemangioma. Methods Infant proliferative hemangioma blocks were implanted subcutaneously into nude mice hemangioma modeling. At 30 days post-implantation, among 65 survivors, 5 nude mice were randomly sacrificed for measuring the volume of…
The immune and lymphatic systems are two closely related organ systems that share several organs and physiological functions (Figure 19.1). The immune system is the defense system against infectious organisms (such as bacteria and viruses) and foreign materials. Through a series of molecular binding and signaling even…
The Nobel laureate Herman Staudinger first believed that polymers were composed of very large molecules containing long sequences of simple chemical units linked together by covalent bonds and introduced the word macromolecules to describe them. By the early 1930s, most scientists in the field were convinced of the ma…
O momento magnetico de spin (ms) de filmes ultrafinos de magnetita (Fe3O4) determinado experimentalmente por varios grupos de pesquisa apresenta em geral valores muito abaixo do momento encontrado no monocristal (bulk ), o que e muito intrigante. Outra questao em aberto e: qual e a menor espessura para um filme de mag…

The results of a previous work, where it was considered the effect of hole doping on a simple model of the CuO 2 planes in La 2 CuO 4 , are extended. The parameters are adjusted in order to fix the known values of the gap of 2 eV for this material and its dielectric constant of 21. We find again indications of a “hidd…

We propose a hysteretic model for electromechanical coupling in piezoelectric materials, with the strain and the electric field as inputs and the stress and the polarization as outputs. This constitutive law satisfies the thermodynamic principles and exhibits good agreement with experimental measurements. Moreover, wh…
Calculation schemes for solving Sturm-Liouville problem with first-, second-and third-type boundary conditions by finite-element method holding a continuity of derivatives of a required solution in its approximated solution are constructed. Recurrence relations for the calculation in analytical form of the interpolati…
Ce travail de thèse s’inscrit dans un programme de recherche européen qui vise à développer de façon rationnelle de nouveaux catalyseurs possédant une activité et une sélectivité élevées pour le vaporeformage du méthanol. L’impact socio-économique de cette réaction est considéré comme très important puisque le méthano…
It can be shown that independently of the individual chemical compositions of coolants, they contain positively charged particles (ions). These are necessary to compensate for the negative charge of the metal surface due to the cathode and anode areas of corrosion in the engine cooling system. These particles can ente…
The paper is devoted to research waste water solutions, solutions from galvanic workshops. The model solution made in distilled water and also in real waste made by similar scheme has been used for research. Investigations were carried out under different conditions possible in the actual production of printed circuit…
En chromatographie en phase gazeuse, la miniaturisation ouvre la voie pour de nouveaux appareils portables, consommant peu d'énergie et de gaz et permettant des analyses directement sur site en évitant ainsi le transport d'échantillons. Depuis les années 70, l'essentiel des travaux s'est focalisé sur les hydrocarbones…
This PhD project is focused on the development of new polymeric materials with antibacterial and antifungal activity. The first part of the work was dedicated to the synthesis and the insertion of a modified amino acid into an antimicrobial peptide (AMP), with the aim to retain the action mechanism on bacterial membra…
41 % of European sludge is used in agriculture. They contain organic micropollutants which are toxic and persistent compounds found at low levels in aquatic environment but have huge impacts on environment. During biological treatment of sludge, the micropollutants are removed by sorption or biodegradation; the treatm…
Mesin pengering kunyit ini menggunakan kompor sebagai media pemanas dengan tabung LPG 3 Kg sebagai bahan bakarnya. Mesin ini menggunakan penampang penahan berupa pelat stainless stell supaya panas yang dihasilkan dari kompor tidak langsung mengenai kunyit, dan untuk loyang di tata secara siksak agar udara panas bisa b…
