The extreme light infrastructure-nuclear physics (ELI-NP) facility: new horizons in physics with 10 PW ultra-intense lasers and 20 MeV brilliant gamma beams.

The European Strategy Forum on Research Infrastructures (ESFRI) has selected in 2006 a proposal based on ultra-intense laser fields with intensities reaching up to 10-10 W cm called 'ELI' for Extreme Light Infrastructure. The construction of a large-scale laser-centred, distributed pan-European research infrastructure, involving beyond the state-of-the-art ultra-short and ultra-intense laser technologies, received the approval for funding in 2011-2012. The three pillars of the ELI facility are being built in Czech Republic, Hungary and Romania.

Multifaceted Quadruplet of Low-Lying Spin-Zero States in ^{66}Ni: Emergence of Shape Isomerism in Light Nuclei.

A search for shape isomers in the ^{66}Ni nucleus was performed, following old suggestions of various mean-field models and recent ones, based on state-of-the-art Monte Carlo shell model (MCSM), all considering ^{66}Ni as the lightest nuclear system with shape isomerism. By employing the two-neutron transfer reaction induced by an ^{18}O beam on a ^{64}Ni target, at the sub-Coulomb barrier energy of 39 MeV, all three lowest-excited 0^{+} states in ^{66}Ni were populated and their γ decay was observed by γ-coincidence technique. The 0^{+} states lifetimes were assessed with the plunger method, yielding for the 0_{2}^{+}, 0_{3}^{+}, and 0_{4}^{+} decay to the 2_{1}^{+} state the B(E2) values of 4.

Comparative study of clinical-morphological profiles of different types of gastric carcinoma.

Aim: Gastric carcinoma shows considerable variation in the histological pattern and degree of differentiation. The aim of the study was to assess especially the morphological differences between gastric carcinomas revealing one morphological feature and those including two morphological features.

Materials And Methods: Two groups of patients were selected: Group 1, including 43 patients with tumors revealing only one architectural pattern, and Group 2, including 16 patients with two architectural patterns within the tumor.

Radiological protection evaluation of the Bucharest Tandetron 3 MV accelerator.

Low energy heavy charged particle accelerators are generators of ionizing radiation, due to the ion beam interactions into the machine components, targets and surrounding materials. Nowadays there are available computational tools allowing realistic estimates of radiation doses and residual activity of the activated components. These evaluations are further used to design the radiological safety system required by licensing and operation of the equipment.

Gamma-ray fast-timing coincidence measurements from the 18O+18O fusion-evaporation reaction using a mixed LaBr3-HPGe array.

We report on a gamma-ray coincidence analysis using a mixed array of hyperpure germanium and cerium-doped lanthanum tri-bromide (LaBr3:Ce) scintillation detectors to study nuclear electromagnetic transition rates in the pico-to-nanosecond time regime in 33,34P and 33S following fusion-evaporation reactions between an 18O beam and an isotopically enriched 18O implanted tantalum target. Energies from decay gamma-rays associated with the reaction residues were measured in event-by-event coincidence mode, with the measured time difference information between the pairs of gamma-rays in each event also recorded using the ultra-fast coincidence timing technique. The experiment used the good full-energy peak resolution of the LaBr3:Ce detectors coupled with their excellent timing responses in order to determine the excited state lifetime associated with the lowest lying, cross-shell, Iπ=4- "intruder" state previously reported in the N=19 isotone 34P.

Invasion assessment in gastric carcinoma - imagistic and histopathologic combined study.

Introduction: Imagistic examinations have an essential role in the assessment of gastric cancer both in earlier and advanced stages. Among these, endoscopic ultrasound (EUS) especially contributes to the diagnosis by direct visualization of the tumor and to the staging and prognosis assessment through the evaluation of the gastric wall and regional lymph nodes. Computer tomography (CT) examination also has an important role, especially in advanced stages, in the assessment of the prognosis, contributing to TNM staging.

The role of endoscopic examination accompanied by histological examination on biopsy samples in the diagnosis of gastric carcinoma.

Introduction: Endoscopic evaluation is one of the most important explorations in the diagnosis of gastric cancer, increasing its value by adding biopsy sampling and histopathologic examination, especially in early forms of gastric malignant proliferations. The aim of this study was to evaluate some descriptive parameters of macroscopic and microscopic aspects of gastric carcinomas defined with the help of endoscopic investigation and gastric biopsies sampled during endoscopic examination, and their correlation with patient survival.

Materials And Methods: The study was performed on a group of 119 patients diagnosed with gastric carcinoma.
