Considering the rising prevalence of smartphone usage among adolescents with intellectual disabilities and their frequent motor challenges, understanding its impact on physical well-being is important. This study aims to investigate activities postural balance in disabilities. Two groups participated study: an disability group (IDG) (n = 16) atypical development (TDG) 12). Static balance, using a stabilometric platform firm foam surfaces, dynamic Timed Up-and-Go Test (TUGT), were performed...
This paper presents a plane equivalent model of the vehicle and its mathematical attached. The is under form four differential equations system order 1, in to analyze dynamic behaviour movement. Its goal determine ranges speed for that movement stable or unstable, having chaotic character. authors consider being necessary know conditions which movements occur avoid them through constructive functional limitations. Speed values are identified placed quasiperiodic field exceeding these...
The paper presents the studies made on a similar biomechanical system composed by neck, head and dummy body components. models were defined in CAD environment which includes Adams algorithm for dynamic simulations. After simulation was obtained entire mechanical behavior based data tables or diagrams. That virtual model neck included complex (as car system) supposed to impact simulations (virtual crash tests). This issues concerning use of systems modern technology prototyping, this case...
Abstract This paper presents a study with finite elements of the rear axle car. The virtual model assembly vehicle is made. Based on this we made state stresses and strains that occur in components suspension. When constructing analysis model, considered bearing conditions, as well loads from real operation assembly. purpose element to determine most requested areas assembly, compare results obtained for specific deformations experimentally those by analysis. Also, through elements,...
To describe the characteristics of clients who enrolled into an opt-in, HIV, HBV & HCV Voluntary Counseling and Testing Program in Dobrogea Region, Romania (VCT) to identify utility pre-test counseling sessions increasing subjective perception regarding transmission knowledge for attending VCT program.Cross sectional data collection, between August 2015 September 2016. Sociodemographic behavioral information were collected at two Baylor centers. Counselors trained delivery standardized...
This paper presents the analysis and way of determining commercial speed for a public transport route (a line) people from Craiova. Calculate optimal distance between stations on under consideration, which will ensure minimum journey time passengers. Commercial was determined according to length its time, depends number stations, passenger flow traffic conditions specific
This paper presents the design and manufacturing aspects of these tools. Constructive geometric peculiarities are exposed for gear hobbing cutter with large modules. The modified profile in parametrized variant permits a rapid adaptation to any conditions. Depending on particular constructive it was created virtual prototype (solid model). is analyzed and, final stage, manufactured [1,2,3,4,] . Manufacturing techniques tool include obtaining profiled knifes clearance (achieved by increased...
The necessity of technical education structure and content in the organization system on three cycles conform to Bologna model must be taken concordance with Engineering occupation goods production, services, research-development Romania. general necessities are particularized for Graphics from
The COVID-19 vaccination program was made available in Romania first to vulnerable and at-risk groups specific state-run centers, where people could get an appointment receive the shot. People Living with HIV/AIDS (PLWHA) represent such a group. In context of widespread misinformation debate about need for vaccination, our team took proactive approach assess levels intentions among unvaccinated. 100 PLWHA who declared ambivalent or unprepared take vaccine were offered one online in-person...
The paper presents a modal analysis for the helicoidally spring from compound of Macpherson automotive suspension. In first part, it is described device used experimental study and then, measurement equipment used, too. First all, represented kinematical scheme 3D representation mechanism included necessary to dynamic analysis. After this, are made some measurements different parameters obtaining values which compared finally with simulation results.
In this paper is made a tridimensional model for the stand use testing of helicoidally springs from automotives suspension using Solid Works soft. Then, it realized simulation springs. On 3D-model dynamic analysis obtaining variation stresses and deformation all parts stand.
Using the experimental determinations obtained on basis of compressive stress, some mechanical properties were studied for composite materials with matrix three types resin, epoxy, unsaturated polyester and hybrid based Dammar natural which was reinforced isophthalic resin granules NPG (Neopentyl Glycol) Chromat Kayan / Javari Payette type. The stress-strain diagrams, yield strength, strength modulus elasticity in uniaxial compression obtained. With EDS analysis, graphical distribution...
This study focuses on middle schoolers who undergo a period of transformation from preteen to teenager years. The situation concerning this category is alarming worldwide because these children are prone obesity. Our research aimed the results in trial resistance running and determine whether suffered modifications BMI. features for 800m girls, 1000m boys, differentiation indicator, i.e., group comprised 94 seventh graders (40 boys 54 girls) Iași County (Romania). Upon interpreting BMI...
This study aimed to prove the efficiency of circuit training in Physical Education class for eighth graders. The study’s objective was analyse results obtained five force and endurance trials. As research subjects, they comprised 63 graders, 36 boys 27 girls. tests used were running: 800m girls/1000m boys, trials lower limbs: standing long jump squats, abdominal force: torso raises 30” arm push-ups 30”. Findings have proven significant differences between pre-test post-tests among From a...
In this research some composite materials built in sandwich type style are studied. The lower and upper layers, that reinforce the samples, made from poplar strips. core is crushed corn cob adhesion of all parts (layers core) by using hybrid resins based on a combination dammar resin synthetic acrylic one (with its hardener). static dynamic mechanical behaviour testing samples to tensile bending were Two types used: abbreviated as B with percentage 60% 40% hardener C 65% 35% hardener.
