purpose: to describe a new noninvasive method to assure correct orientation of donor lenticules in descemet stripping automated endothelial keratoplasty (dsaek) surgery. methods: dsaek surgery was performed in three eyes with the diagnosis of pseudophakic bullous keratopathy (pbk). for the laboratory part of the study, two whole globes and two precut corneoscleral buttons were used. the donor l...

a dynamic two dimensional problem of thermoelasticity with double porous structure has been considered to investigate the disturbance due to normal force and thermal source. laplace and fourier transform technique is applied to the governing equations to solve the problem. the transformed components of stress and temperature distribution are obtained .the resulting expressions are obtained in t...

‎highest weight modules of the double affine lie algebra $widehat{widehat{mathfrak{sl}}}_{2}$ are studied under a‎ ‎new triangular decomposition‎. ‎singular vectors of verma modules are‎ ‎determined using a similar condition with horizontal affine lie‎ ‎subalgebras‎, ‎and highest weight modules are described under the‎ ‎condition $c_1>0$ and $c_2=0$.

the use of panoramic radiography, due to its numerous advantages, is increasing. radiographic films used in this technique are of double emulsion (de) type which are used with intensifying screens. single emulsion (se) films can also be used. the purpose of this study was to determine the exposure parameters to achieve an appropriate optical density in these two types of films, and to estimate ...

background: this study was done to determine the prevalence of publication misconduct among iranian authors. methods: data were collected through an email survey of corresponding authors of papers published in iranian journals indexed in scopus during 2009-2011. using the double list experiment, these individuals were indirectly questioned about committing one of the five misconducts including ...

background : approach to the small intestine has been difficult even with newer methods. double-balloon enteroscopy (dbe) has been created for diagnostic and therapeutic interventions in diseases of the small intestine. small intestinal diseases have different etiologies in each country. the dbe has been introduced in recent years in iran. our aim was to study the indications and results of dbe...

background: sick leave from work due to psychiatric disorders is a major public health problem, not only in japan but also worldwide. as males and females in japan tend to differ in their approach to work, a gender difference in perfectionism might be expected. we investigated the background factors leading to long-term absence from work due to sickness among psychiatric outpatients in japan . ...

two-dimensional electrophoresis (2-d electrophoresis) is a powerful and extensively used method for analysis of complex protein mixtures extracted from cells, tissue, or other biological samples such as helminth parasites including, f. hepatica. each spot on the resulting two-dimensional collection corresponds to a single protein species in the sample. this study was carried out to detect of gs...

“wild thorns” is a novel written by the palestinian novelist sahar khalifeh; it focuses on the colonisation of palestine from a feminist point of view. she considers the israeli colonisation as a patriarchy. this paper aims at investigating two types of colonization that have been represented in the form of patriarchy in the novel. the investigation of the issue of palestine from a feminist poi...

the aim of this paper is to introduce and study a new concept of strong double δ ( a ) σ -convergence sequences with respect to an orlicz function, and some properties of the resulting sequencespaces were also examined. in addition, we define the δ ( a ) σ -statistical convergence and establish someconnections between the spaces of strong double δ ( a ) σ -convergence sequences and the space of...
