In this paper, the resonant frequency and sensitivity of an atomic force microscope (AFM) with an assembled cantilever probe (ACP) are analyzed utilizing the modified couple stress theory. The proposed ACP comprises a horizontal microcantilever, an extension and a tip located at the free end of the extension, which make AFM capable of scanning the sample sidewall. First, the governing different...
Background and objective: Some people had allergy to different materials and these patients they experience some clinical appearances after contact specific allergen had seen. With the epidemiological rising in allergy to the non-alimentary allergens, we want to assessment the allergic reactions ‘frequency to non- alimentary allergens among native population and universities ‘studen...

narrative frequency is one of the main temporal and stylistic categories as well as an important miraculous aspect de-familiarizing qur’an. the story of adam is among the qur’anic stories that have been repeated in seven verses. of the artistic aspects of this story, it can be referred to its narrative dissemination. the types of frequency differing from singular, anaphoric, style and anaphoric...
What are the dynamics and regularities underlying social contact, and how can contact with the people in one's social network be predicted? In order to characterize distributional and temporal patterns underlying contact probability, we asked 40 participants to keep a diary of their social contacts for 100 consecutive days. Using a memory framework previously used to study environmental regular...
BACKGROUND Non-celiac wheat sensitivity (NCWS) is a new clinical entity in the world of gluten-related diseases. Nickel, the most frequent cause of contact allergy, can be found in wheat and results in systemic nickel allergy syndrome and mimics irritable bowel syndrome (IBS). Objective: To evaluate the frequency of contact dermatitis due to nickel allergy in NCWS patients diagnosed by a d...
Aerospace engines testing is a source of noise pollution and determining the low frequency acoustic characteristics of the test cell, plays an important role in optimally control of the sound field and reducing the level of sound pressure and pollution. In this study, the drop in average sound pressure level is numerically predicted by constructing a test cell according to ISO 140 standard. To ...
