آنتنها اصولأ در حالت تنها و مجزا قرار ندارند، تشعشع از سمت یک منبع، آنتن گیرنده را تحریک کرده، مانند هر عاملی که در اطراف آن قراردارد. میدان های متغیر با زمان با اشیاء مختلف در محیط برخورد کرده، که میدان ها را جذب یا منعکس می کنند. بنابراین، عملکرد آنتن در فضای آزاد با محیط واقعی اطراف آن متفاوت خواهد بود. تعامل بین آنتن و محیط اطرافش به عنوان تزویج متقابل شناخته می شود، که دارای سه بخش بوده ک...
BACKGROUND We report the ophthalmic findings of a patient with type Ia glycogen storage disease (GSD Ia), DiGeorge syndrome (DGS), cataract and optic nerve head drusen (ONHD). CASE PRESENTATION A 26-year-old white woman, born at term by natural delivery presented with a post-natal diagnosis of GSD Ia. Genetic testing by array-comparative genomic hybridization (CGH) for DGS was required becaus...
Myeloperoxidase (MPO) generates reactive halogenating species that can modify DNA. The aim of this study was to investigate the formation of 8-halogenated 2'-deoxyguanosines (8- halo-dGs) during inflammatory events. 8-Bromo-2'-dG (8-BrdG) and 8-chloro-2'-dG (8-CldG) were generated by treatment of MPO with hydrogen peroxide at physiological concentrations of Cl(-) and Br(-). The formation of 8-h...
AIM To investigate the morphology and function of platelets in nephropathic cystinosis (NC). METHODS Seven patients (mean age, 6.5 years; SD, 20 months) with NC were investigated. Their platelets were examined by transmission electron microscopy (TEM) and the characteristics of the dense granules (DGs) were determined by mepacrine labelling and the uranaffin reaction. Bleeding time, turbidome...
The chromosome 22q11 region is susceptible to rearrangements that are associated with congenital anomaly disorders and malignant tumors. Three congenital anomaly disorders, cat-eye syndrome, der() syndrome and velo-cardio-facial syndrome/DiGeorge syndrome (VCFS/DGS) are associated with tetrasomy, trisomy or monosomy, respectively, for part of chromosome 22q11. VCFS/DGS is the most common syndro...
Colon tumor cells are more responsive to certain growth modulators in their local environment in vivo than are normal colonocytes. Examples of this class of compounds are the fecal diglycerides (DGs)(E. Friedman et al., Cancer Res., 49: 544-548, 1989), which may act as endogenous tumor promoters. At the concentration found in vivo, fecal DGs composed of oleic, myristic, and palmitic fatty acids...
Recently, increasing of non-linear loads in the power distribution network has been increased harmonics in these networks. The harmonics problems get worse and complicated by installation of power factor correction capacitors and filters. But the Distributed Generations (DGs) interface inverters with properly control can help to improve power quality, harmonic compensation and voltage unbalance...
We investigate whether the spectral-type of a locally dominant (most luminous) galaxy can be used to select sets of galaxies that are physically associated (groups). We assume that passive dominants trace a group-like potential, and SF-dominants a field-like environment. The group sample includes 988 groups selected in the 2dFGRS applying a maximum magnitude difference criterion. We find that t...
abstract: enviromental concerns, improvements in renewable energy technologies, governmental incentives for the use of these resources, and increased t&d; costs, are the main factors driving the energy sector into a new era, where considerable portions of electrical demand will be met through widespread installation of distributed energy resources (ders). the virtual power plant (vpp) is a dece...
