an investigation was carried out on a young unrelated couple, both 29 years old, with two boys and three girls, 3 months to 8 years old. one boy and the mother were healthy, the other four children and the father were affected. the family, originally from the district of nour, in northern iran, near the caspian sea, was first counseled at the genetic clinic in tehran in 1984. several trips were...

background: in algeria, the data on infertility and its various causes are rare. recently, the introduction of assisted reproduction has allowed expecting that 300000 couples, which represent 7% of couples of reproductive age, face difficulty conceiving a child. knowing that most idiopathic cases are likely to be due to chromosomal abnormalities, we aimed to investigate genetic defects by karyo...

Four halotolerant fungal isolates originating from the saltwater Lake Urmia in Iran were selected during a screening program for salt resistance and α-amylase activity. The isolates were identified based on sequencing the ITS region and a part of the β-tubulin gene, as Penicillium chrysogenum (isolate U1; CBS 132820), Fusarium incarnatum (isolate U2; CBS 132821), and Penicillium polonicum (isol...

living in satisfying urban environments is important for an individual’s well-being. in order to create such environments, planners, designers, and policy makers need to understand the structures that cause residents to feel satisfied with their environments. this paper focuses on the perceived quality of urban residential environments: dwellings and neighborhoods. first, literature review was ...

Micro-powered wireless sensors present new challenges due to the severe harvesting conditions under which they need to operate and their tiny energy reservoirs. However, existing lowpower network stacks make a slew of design choices that limit the ability to scale down to such environments. We address these issues with QuarkNet, a backscatter-based network stack that is designed to enable conti...

The acquisition of dense 3D data sets is of great importance, but also a challenge for scanning probe microscopy (SPM). Thermal drift often induces severe distortions in the data, which usually constrains the acquisition of dense data sets to experiments under ultra-high vacuum and low-temperature conditions. Atom tracking is an elegant approach to compensate for thermal drift and to position t...

OBJECTIVES This study examines the issue of living environments for persons with acquired brain injury (ABI), with the aim of identifying factors that enable or act as barriers to appropriate living environments. METHODS A qualitative study involving 31 semi-structured interviews conducted with 56 key informants representing various relevant sectors: institutional, community, residential and ...

The formal deenition of any namespace device found in a programming language can be given in terms of transformations on a semantic environment. It is therefore worthwhile to consider the implications of incorporating environments as bona de data objects in a programming system. Because of their expressive power, environments can be easily abused. Reifying an environment can entail the capture ...
