In this work, the method of iterative Fourier transform phase reconstruction, conventionally used in holography and optical image reconstruction, is applied to phase only synthesis of antenna patterns. The method is applied to two types of pattern synthesis problems: "main lobe beam shaping" and "side-lobe-level reduction". The proposed method is most useful in the efficient employment of attai...

sulfur mustard (sm) gas was used in the iran-iraq war (1981 - 1989) as a vesicant chemical warfare against the iranian warriors. this alkylating agent with the potential of producing chemical injury in the skin, eyes, and lung, may damage both upper and lower respiratory tract, which in turn can cause different types of sequels such as asthma, bronchiectasis, chronic bronchitis and lung fibrosi...

background and aim: electrical discharges in temporal lobe epilepsy can cause disorders in auditory pathways. staggered spondaic word test ( ssw) is one of the most common behavioral tests to evaluate the central auditory nervous system. this study aimed to evaluate and compare auditory processing problems in temporal lobe epileptic patients and normal subjects with persian ssw test. methods: t...

epilepsy is one of the most common neuroinflammatory disorders that affect more than 50 million people worldwide. excessive electrical discharges in neurons following neural cell damage or loss leads to recurrent seizures, which are described as epilepsy. one of the most common and difficult to treat types of epilepsy is temporal lobe epilepsy (tle), which results from hippocampal sclerosis. cu...

introduction : shared neuropathology hypothesis in schizophrenia and temporal lobe epilepsy has been introduced long term ago. similar neuropathology leads to the analogous clinical features like neuropsychological features as an example. the aim of this study was to examine this hypothesis by the means of comparing neuropsychological functions in these two patient groups. method : present stud...

the aim of the present study was to investigate the effect of gender on the distribution of pancreatic islets in native chicken. ten adult male and ten adult female isfahan native chickens were used in this experiment. results showed a distinct sexual dimorphism in the native chicken pancreas which depends upon the various fractions of the pancreatic lobes, which were occupied by alpha, beta an...

background and objective: temporal lobe epilepsy (tle) is a chronic neurological disorder with spontaneous recurrent seizures and abnormal intracranial waves. since the role of oxidative stress in the occurrence of epilepsy is inevitable, it seems that the use of antioxidants can prevent some of the complications resulting from this disease. this study was designed to assess the protective effe...

in this paper, the static characteristics of two-lobe, three-lobe and four-lobe noncircular gas journal bearing systems are studied in detail. the reynold’s equation governing the noncircular gas bearing systems are analyzed by using radial basis functions (rbf). the solutions are obtained numerically by solving systems of algebraic equations. the equilibrium position of the rotor is obtaine...
