Electrochemical noise data is commonly used to monitor corrosion of metals in various environments. In this work we use recurrence plots to study electrochemical noise time series of stainless steel AISI 316 samples immersed in mildly corrosive electrolyte. It has been found that current and potential time series reveal different information. Recurrence quantification analysis of current time s...

The problem of summing a set of mutual recurrence relations with constant coefficients is investigated. A method is presented for summing an order d system of the form A(n) = ∑d i=1 MiA(n − i) + G(n), where A,G : N → K and M1, . . . ,Md ∈ Mm(K) for some field K and natural number m. The procedure expresses the sum ∑n i=0 A(i) in terms of A(n), . . . , A(n− d), initial conditions and sums of the...

peripheral calcifying cystic odontogenic tumor (pccot) is a rare odontogenic lesion, which represents about 1% of jaw cysts. here we report clinicopathologic, radiographic and ct scan images of a new case of recurrent large pccot located in mandibular gingiva in a 77-year-old male with history of a nodular mass in the same area, which had been completely excised 3 years ago. in reviewing the li...

t akotsubo cardiomyopathy (tcm), also known as stress-induced cardiomyopathy, is a clinical syndrome of transient left ventricular (lv) apical wall motion abnormality with relative preservation of the basal heart segments in the absence of any significant atherosclerosis. recurrence of this condition is rare. we report a postmenopausal woman, who experienced two episodes of tcm within 4 months ...

conclusions based on the findings of the study, it can be concluded that self-efficacy beliefs and social support play effective roles in preventing patients from addiction relapse. results findings revealed significant differences between participants without relapse and participants with relapse in terms of “self-efficacy beliefs” and “social support”. the two variables of self-efficacy belie...
