background: a boron neutron capture therapy (bnct) facility, based on a dt neutron generator, with the final goal to find out a potential, alternative, solution to existing bnct treatment facilities which are based on nuclear reactors is examined. materials and methods: with the aim of the mcnp4b monte carlo code different beam-shaping assembly (bsa) configurations were considered. lead was sel...

preparation of chitosan (cs) microspheres as a novel drug delivery vehicle for intranasal immunization using high, medium and low cs molecular weight (mw) was investigated in this study. diphtheria toxoid (dt) was used as a model antigen. the emulsion-solidification method was adopted for microencapsulation of dt.  in the first step, following the purification of semi-crude dt by the ion-exchan...

A et al. Updated clinical classification of pulmonary hypertension. Assessment of right ventricular systolic function with dP/dt in healthy subjects: an observational study. Deformation imaging describes right ventricular function better than longitudinal displacement of the tricuspid ring. Factors that prognosticate mortality in idiopath-ic pulmonary arterial hypertension: a systematic review ...

in this short article, we observe that the path of particle of mass $m$ moving along $mathbf{r}= mathbf{r}(t)$ under pseudo-force $mathbf{a}(t)$, $t$ denotes the time, is given by $mathbf{r}_d= int(frac{dmathbf{r}}{dt} mathbf{a}(t)) dt +mathbf{c}$. we also observe that the effective force $mathbf{f}_e$ on that particle due to pseudo-force $mathbf{a}(t)$, is given by $ mathbf{f}_e= mathbf{f} mat...

conclusions vaccine based on the conjugation of p. aeruginosa pao-1 lps with dt increased anti-lps antibodies and had a significant potential to protect against pseudomonas infections. background treatment of pseudomonas aeruginosa pao-1 infections through immunological means has been proved to be efficient and protective. objectives the purpose of this study was to produce a conjugate vaccine ...

Background Routine screening for distress is internationally recommended as a necessary standard for good cancer care given its high prevalence and negative consequences on quality of life. This study attempts to support validation of Distress Thermometer (DT) in Shiraz, Iran and in the second step to investigate privilege/priority of DT over other referent criterion measures. Material and m...

The reactivity of a fuel assembly including burnable absorbers can become the largest at low burnup, so accuracy calculations for such systems is important. To investigate this issue, impact gadolinium isotopes’ nuclear data on neutron multiplication factor k quantified. Sensitivities to are calculated from 0 20 GWD/t BWR 3 × multicell model. Sensitivity gadolinium-157 (n,γ) cross section becom...

The mass transfer performance of a pulsed disc and doughnut column for extraction of samarium and gadolinium from aqueous nitrate solution with D2EHPA was investigated. The effects of operating parameters such as pulsation intensity, continuous and dispersed phase velocities on column performance were investigated. The axial dispersion model was used to obtain the overall mass transfer coef...
