The aim of the paper is to identify optimal plastic type used in obtaining thoraco-lumbar orthoses - treatments comminutive fracture, burst fracture vertebrae lumbar area. For this purpose, with help Finite Element Analysis (FEA), a theoretical study was carried out on influence elastic properties plastics, achieving orthoses, state tension and local displacements bone fragments from traumatized area under condition movement base extension flexion. In force flexion, modulus material varied...
The rapid development achieved over the last decades in volume rendering of ultrasound data, known as three‑dimensional (3D) technique, leads to new opportunities for refining diagnosis many gynaecologic conditions. aim present study was evaluate advantages 3D two‑dimensional (2D) uterine pathology and establish optimal time point during menstrual cycle perform examination order achieve maximum useful information. A cross‑sectional on 200 patients who underwent 2D examinations performed....
Abstract In this paper the surfaces of some steel samples, low alloyed, were covered by electric arc thermal spray with a layer, high containing FeNiCrSiB-WC/TiC, using core wire. order to study influence process parameters on obtained deposits, surface roughness and intensity current varied three levels rest technological kept constant. The microstructural characteristics, chemical composition, physical mechanical properties deposits investigated SEM analysis microhardness X-ray...
The purpose of this study was to evaluate the association between follicle-stimulating hormone (FSH) receptor (c.-29G>A) and FSH beta chain (c.-280G>T) polymorphisms endometriosis in Romanian women.We performed polymorphic analysis gene 44 patients with 34 controls. Genomic DNA obtained from peripheral blood were investigated using restriction fragment length polymorphism (RFLP).There no significant differences genotype frequencies For heterozygous type we did not find a difference its...
In this paper it has been deposited films of titanium oxide (TiO 2 ), on a support glass, by D.C. magnetron sputtering system, varying the working pressure (p = 2∙10 -3 - 6.5∙10 mbar) substrate temperature three levels. The obtained layers were investigated and characterized optical microscopy, Scanning Electron Microscopy SEM, X-ray diffraction Atomic Force Microscopy. It was observed that, modifying technological parameters process (working temperature) is changing initial orientation...
Machine learning is a branch of artificial intelligence that allows computer systems to learn directly from examples, data, and experience. Statistical modeling more about finding connections between variables consequently the impact these relationships, while also catering for prediction. It should be clear two methodologies are different in terms their purpose, despite fact they use similar means get there. The evaluation machine algorithm uses set tests validate its accuracy. Although,...
Two different operational procedures are proposed for evaluating and predicting the onset of epileptic eclamptic seizures. The first procedure analyzes electrical activity brain (EEG signals) using nonlinear dynamic methods (the time variations standard deviation, variance, skewness kurtosis; evolution in spatial–temporal entropy; Lyapunov coefficients, etc.). second reconstructs any type EEG signal through harmonic mappings from usual space to hyperbolic one homographic invariance a...
Endometriosis is considered a serious public health issue because of the large number females affected by this illness. Chronic pain management in patients with endometriosis demands new strategies to increase life quality these patients. The development drug delivery systems represents approach treatment among Diclofenac sodium, one most utilized nonsteroidal anti-inflammatory drugs (NSAID), has its own limitations when being used formulas such as oral, parental, or local applications. In...
In this paper, layers of TiO2 were deposited, by magnetron sputtering, on a glass support. The parameters the deposition process kept constant except for O2/(Ar + O2) ratio that varied three levels. physical and mechanical properties obtained investigated SEM optical microscopy, electronics, AFM X-ray diffraction. bioactivity surfaces was growing M3C3-E1 osteoblast cells produced RIKEN Cell Bank (Japan) period 5 days. modification working environment in enclosure determines both phasic film,...
Labial fusion is a rare condition typically observed in prepubescent girls, but it can also occur postmenopausal women due to estrogen deficiency.
In this paper it is presented a comparative theoretical study - performed by finite element analysis (FEA), of the tension state that appears at level spine, as well in areas adjacent to it, under following conditions: a) existence comminutive fracture vertebra T11; b) external immobilization body through Lombax orthesis (LO) or internal column means spinal fixator (SF); c) performing some basic flexion extension movements. study, both flexural force and varied on three levels. The results...
Infertility is defi ned as the inability of a couple to conceive child after 12 months regular and unprotected sexual intercourse or 6 months, in case women who are over 35 years.Currently, assisted human reproductive techniques (ART) can help infertility couples worldwide promise unquestionable benefi ts humanity.The study proposes an assessment problems that with fertility issues facing Romania using special questionnaire composed 8 segments 65 items.The was completed by 860 ted from ART...
The main objective of this paper is to evaluate the mechanical properties, chemical and corrosion resistance four types metallic coatings: FeCr, FeCoCr, FeCoCrNi, FeCrNi sprayed through thermal spraying in electric arc on an anchor substrate type 95Ni5Al or 78.3Ni20Cr1. 4Si0.3Fe. five layers tested were deposited carbon steel support low alloyed obtained results have provided a picture regarding possibilities using deposits. Because these alloys are used increase wear tools, it very...
Influence of the process parameters and geometry spraying nozzle on properties titanium deposits obtained in wire arc spraying.
