in this paper, welding feasibility between aa1100, aa5050 and aa6082 aluminum alloys and a441 aisi steel by friction stir welding has been studied. mathematical analysis of the heat generation during process showed that the maximum temperature produced in aa6082 aluminum alloy and a441 aisi joint but heat distribution in aa1100 aluminum alloy was higher than the other alloys. the investigation ...

Typical interstitial pneumonia (IP) is mainly the fibrotic form of lung disease. In some cases with typical IP, a certain amount ground-glass opacity (GGO) can be detected on high-resolution computed tomography, however, important issues, such as co-existence GGO and still require further investigation by biopsy. After diagnosis anti-fibrosis treatment usually considered. Here, we hypothesized ...

Zusammenfassung Diese Studie präsentiert die Anwendung der Induzierten Polarisation (IP) für Charakterisierung einer Graphitlagerstätte. Basierend auf Labormessungen zeigen wir Sensitivität von IP-Messungen hinsichtlich Veränderungen Korngröße und spezifischen Oberfläche Graphit in Gesteinsproben Feldskala. Des Weiteren demonstrieren wir, dass IP-Feldmessungen eine klarere Abgrenzung graphitrei...

Let $(X,T)$ be a topological dynamical system and $n\geq 2$. We say that is $n$-tuplewise IP-sensitive (resp. thickly sensitive) if there exists constant $\delta>0$ with the property for each non-empty open subset $U$ of $X$, exist $x_1,x_2,\dotsc,x_n\in U$ such \[ \Bigl\{k\in\mathbb{N}\colon \min_{1\le i\delta\Bigr\} \] an IP-set thick set). obtain several sufficient...
