In the past, there has been a tremendous progress in the area of autonomous robot navigation and a large variety of robots have been developed who demonstrated robust navigation capabilities indoors, in non-urban outdoor environments, or on roads and relatively few approaches focus on navigation in urban environments such as city centers. Urban areas, however, introduce numerous challenges for ...

The genus Tanacetum L. is one of the most important medicinal plant that contains 28 species in Iran, 12 of them are endemics. This paper reports the essential oil composition of Tanacetum hololeucum (Bornm.) Podlech; Tanacetum kotschyi (Boiss.) Grierson, growing wild in Iran. Plant flowers were collected from different zones of Dizin in north of Iran. All samples were hydro-distilled (Clevenge...

UNLABELLED A pessimistic view of the impact of armed conflicts on the control of infectious diseases has generated great interest in the role of conflicts on the global TB epidemic. Nowhere in the world is such interest more palpable than in the Horn of Africa Region, comprising Ethiopia, Somalia, Eritrea, Djibouti, Kenya and Sudan. An expanding literature has demonstrated that armed conflicts ...

OBJECTIVE To assess the sizes and configurations of thermal zones after overlapping ablations using a coaxial radiofrequency (RF) electrode and multiple cannulae in ex-vivo bovine liver. MATERIALS AND METHODS For ablation procedures, a coaxial RF electrode and introducer set was used. Employing real-time ultrasound guidance and overlapping techniques in explanted, fresh bovine liver, we creat...

Non-destructive defect testing with a passive magnetic detection technique is crucial for materials, which can be exempt from the extra excitation field or developer replenisher contamination. We demonstrate novel and high-resolution non-destructive of turbine blade in earth’s using precisely controlled experimental system. The variation blade’s field, measured by three-dimensional sensitive se...

Film receptor autoradiography was used to study the distribution of ml-, (r2-, and @-adrenergic receptors in the occipital lobe of developing rhesus monkeys ranging in age from the 65th embryonic day (E65) to adulthood (5 years of age). The study shows that each adrenergic receptor subtype has a unique distribution in the cortical plate and transient embryonic zones of the developing cerebral w...
