Cystic fibrosis (CF) is the most common autosomal recessive disorder in white skinned individuals. Chronic lung infection is the main cause of mortality in this disease. Approximately 60–75 % of adult CF patients frequently suffer from Pseudomonas aeruginosa (PA) infection that is strongly associated with inflammation, lung destruction, and increased mortality. Therefore, CF patients should be ...
the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...
chapter one is devoted to a moderate discussion on preliminaries, according to our requirements. chapter two which is based on our work in (24) is devoted introducting weighted semigroups (s, w), and studying some famous function spaces on them, especially the relations between go (s, w) and other function speces are invesigated. in fact this chapter is a complement to (32). one of the main fea...
abstract the present study was conducted to examine the effect of proficiency on students interaction while carrying out the grammar-based task(s) in collaboration. in particular, the study examines whether the level of proficiency affects the learners’ focus of attention to grammatical and lexical features. the study takes a further step and examines whether there is any difference in the use...
As regards the significant role of stethoscopes in the diagnosis of congenital and adventitious heart diseases and prevention of irreparable complications of these diseases, the quality of hearing sound of these stethoscopes by a physician has a significant impact on the disease diagnosis. This device plays an important role in the early diagnosis of congenital heart and respiratory diseases an...
61] In addition to conventional measurement microphones, dummy heads are more and more used for physical as well as subjective noise evaluation. Within the DIN, a study group (A2 AK8) was formed, analyzing features of commercially available dummy heads. It was found that mainly because of geometrically different shells, different dummy heads produce different sound images. In practical applicat...

In the present study, in order to explain the desirability of the soundscapes of the Timchehs of Tabriz Bazaar, Sound Pressure Level (SPL) and Reverberation Time (RT) have been measured as objective variables of acoustic behavior. Using descriptive questionnaire, subjective assessments were used to determine the quality of soundscape. The research seeks to answer the question of how the spatial...
Sound-quality is a complex and multi-layered phenomenon [1]. When analysing or modelling the formation process of sound-quality judgements, a variety of quality elements and quality features [2] have to be taken into account, whereby the actual relevance and salience of each of them is situation dependent. In this paper, we present some ideas with the aim of structuring the quality-formation pr...
Detecting emotion features in a song remains as a challenge in various area of research especially in Music Emotion Classification (MEC). In order to classify selected song with certain mood or emotion, the algorithms of the machine learning must be intelligent enough to learn the data features as to match the features accordingly to the accurate emotion. Until now, there were only few studies ...
