We investigate the energy efficiency in a wireless sensor networks that implements a non-persistent CSMA MAC protocol with adaptive MQAM modulation at the physical layer. The system throughput is estimated based on the number of received ACK packets. The backoff probability at the MAC layer and the modulation order at the physical layer are jointly adapted according to the traffic dynamics, lea...
introduction: submucoperichondrial injection of botulinum neurotoxin a (bta) in the nasal septum is a promising therapeutic option in the treatment of persistent allergic rhinitis (ar) and non-allergic rhinitis, and is safer and more effective than intraturbinate injection in reducing clinical symptoms. materials and methods: forty patients diagnosed with persistent ar or non-allergic rhiniti...
Discontinuities mainly control the mechanical behavior of rock mass and cause a significant reduction in strength. Joint persistency joint infill conditions are considered most parameters that response mass. In this study, numerical statistical analyses were performed on pre-cracked specimens with two flaws to investigate effect persistence shear addition, an extensive study was conducted explo...
INTRODUCTION Total hip arthroplasty (THA) and total knee arthroplasty (TKA) are highly successful treatment modalities for advanced osteoarthritis. However, prolonged wound leakage after arthroplasty is linked to prosthetic joint infection (PJI), which is a potentially devastating complication. On the one hand, wound leakage is reported as a risk factor for PJI with a leaking wound acting as a ...
Background: Oculo-palato-cerebral syndrome is an extremely rare condition characterized by various features, including low-birth weight, microcephaly, cerebral atrophy, mild-to-severe developmental delay, cleft palate, persistent hyperplastic primary vitreous, microphthalmia, small hands and feet, joint laxity, and large ears with thick helices. Diagnosis of this syndrome is based on the clinic...
introduction: knee joint osteoarthritis is one of the most prevalent musculoskeletal problems in adult population, which cause pain and functional limitations. involvement of medial compartment is almost 10 times more common than lateral compartment, which results in varus deformity among patients with medial compartment osteoarthritis of knee joint. main objectives in the treatment of knee joi...
Aims of the study: Endometriosis is a prevalent gynecologic disorder in young women at reproductiveage but the underlying risk factors have not identified yet in Iran and other neighboringcountries. Persistent exposure to environmental endocrine disrupting chemicals (EDCs) in particulardioxins, PAHs and polychlorinated biphenyls (PCBs) with xenoestrogenic potentials have beenhypothesized in the...
