Density functional approach was used to study the isotropic- nematic (I-N) transition and calculate the values of freezing parameters of the Gay- Berne liquid crystal model. New direct and pair correlation functions of a molecular fluid with Gay- Berne pair potential were used. These new functions were used in density functional theory as input to calculate the isotropic- nematic transition den...
Back ground & Aims: In the edentulous patients some authors suggest to leave dentures in when ventilating with bag-mask. In this research, we suggest a more efficient method. Materials & Methods: In the prospective blind randomized clinical trial we included 200 patients (age≥55) into two groups. After induction of anesthesia in all groups, in the group I, we placed folded gauze in each bucca...
Aim and background: Tracheal intubation remains the choice method for keeping airways open during mechanical ventilation. Among the various methods, standard method of direct laryngoscopy generally used by non-skilled staff increases the risk of failure. This study was performed to evaluate and compare the results of tracheal intubation using laryngeal masks vs. glidescope led by novice personn...
PURPOSE The aim of this study was to prospectively test the hypothesis that 6-fold acceleration of a 3-dimensional (3D) turbo spin echo (TSE) magnetic resonance imaging (MRI) pulse sequence with k-space undersampling and iterative reconstruction is feasible for fast high spatial resolution MRI of the knee, while yielding similar image quality and diagnostic performance when compared with a conv...
In network code setting, a constant dimension code is a set of k-dimensional subspaces of F nq . If F_q n is a nondegenerated symlectic vector space with bilinear form f, an isotropic subspace U of F n q is a subspace that for all x, y ∈ U, f(x, y) = 0. We introduce isotropic subspace codes simply as a set of isotropic subspaces and show how the isotropic property use in decoding process, then...

results the mean heart rate values were significantly less in the sevoflurane group (p value < 0.05) at 25 minutes after the surgery. the mean blood pressure in the isoflurane group was significantly higher compared with the sevoflurane group in 10, 20 and 30 minutes after the surgery (p values = 0.0131, 0.0373 and 0.0028, respectively). these differences were clinically unimportant because hea...
Aims and background: Airway management is one of the key skills in managing and treating of critical patients. In hospital departments before reaching an anesthesiologist or experienced team, this task lies with the nurses who have not been trained enough in this field. This study was conducted to evaluate the ability of nurses before and after a manikin-based workshop for securing the airway ...
treacher collin’s syndrome (tcs) is a rare inherited condition characterized by bilateral and symmetric abnormalities of structures within the first and second bronchial arches. patients with tcs present a serious problem to anesthetists maintaining their airway as upper airway obstruction and difficult tracheal intubation due to severe facial deformity. because of retrognathia, airway manageme...
