Integration and coherence within a city’s physical structure have become an issue for towns and cities as theyrapidly expand, incorporate new elements, and undergo incessant changes. At present, we are facing an extensive accumulation of signs and traits in modern urban patterns; many unaccustomed to and incongruous are affecting the socio-cultural and physical characters of cities. Here, we wi...

A prismatic beam made of a behaviorally nonlinear material is analyzed under aharmonic load moving with a known velocity. The vibration equation of motion is derived usingHamilton principle and Euler-Lagrange Equation. The amplitude of vibration, circular frequency,bending moment, stress and deflection of the beam can be calculated by the presented solution.Considering the response of the beam,...

background: the prevention of work disability is beneficial to employees and employers, and mitigates unnecessary societal costs associated with social welfare. many service providers and employers have initiated workplace interventions designed to reduce unnecessary work disability. objective: to conduct a best-evidence synthesis of systematic reviews on workplace interventions that address ph...

conclusions according to the results of this study, we can conclude that our suggested model is suited to explaining the pathways of stress among iranian male staff. results a total of 575 individuals (all male) were recruited for the study. their mean (±sd) age was 33.49 (±8.9) and their mean job experience was 12.79 (±8.98) years. the pathway of job stress among iranian male staff showed an a...

the present paper aims to examine one of the technically-based approaches in the field of urban planning and urban management which started about two decades ago, and has been tested in iran over the past decade with some scientific and executive prudence. in this paper, the clue_s model, one of the models for land use changes process simulation, is used to examine its efficiency in urbanizatio...
