abstract background: hypertension in pregnancy is one of the prevalent disorders resulting in maternal death. the aim of this study was to investigate the effect of stretching exercise and walking on changes of blood pressure in nulliparous women during pregnancy. materials and methods: this was a quasi-experimental trial that consisted three groups of women who took part in pre- and post-tests...

Density, Raman spectroscopy and viscosity measurements are utilized to probe, respectively, the volume, structural shear relaxation behavior of a Na-Ca-Mg silicate glass standard commercial float composition at ∼80 °C below its calorimetric transition. The results, when taken together, indicate that lowering fictive temperature during aging results in Q-species disproportionation type Q2+Q4→2Q3...

BACKGROUND Plantar heel pain is a commonly occurring foot complaint. Stretching is frequently utilised as a treatment, yet a systematic review focusing only on its effectiveness has not been published. This review aimed to assess the effectiveness of stretching on pain and function in people with plantar heel pain. METHODS Medline, EMBASE, CINAHL, AMED, and The Cochrane Library were searched ...

in this study caulerpa racemosa has been characterized and used for the removal of cd(ii) and pb (ii) from aqueous solutions. the effect of ph, adsorbent dosage, contact time and temperature on adsorption process was studied in batch experiments. langmuir and freundlich models were applied to describe the biosorption isotherm of the metal ions by c. racemosa biomass. the adsorption data can be ...

Stretching in continuum mechanics is naturally described using the Cauchy–Green strain tensors. These tensors quantify the Lagrangian stretching experienced by a material element, and provide a powerful way to study processes in turbulent fluid flows that involve stretching such as vortex stretching and alignment of anisotropic particles. Analysing data from a simulation of isotropic turbulence...
