On weak-BCC-algebras.

TheScientificWorldJournal, 2013
We describe weak-BCC-algebras (also called BZ-algebras) in which the condition (x∗y)∗z = (x∗z)∗y is satisfied only in the case when elements x, y belong to the same branch. We also characterize ideals, nilradicals, and nilpotent elements of such algebras.

Hydrogen‐Assisted Fracture of Iron‐Based Fe–Ni–Al Alloys

Advanced Engineering Materials, EarlyView.
Principal relations and fracture mechanisms of single‐phase and precipitate‐strengthened Fe–Ni–Al alloys subjected to prior electrochemical hydrogen charging are identified. The mechanisms of hydrogen effect on strength and microhardness are discussed, including hydrogen‐induced increase in microhardness and the role of hydrogen in fracture behavior ...

Melolabial Advancement Flap for High-Risk BCC Near the Medial Eye Angle: Phototoxicity/ Photocarcinogenicity Triggered by Nitrosamines in the Polymedication as the Main Cause of Keratinocyte Cancer Development and Progression

Acta Medica Bulgarica
The enigma that lies behind the concept of drug-mediated phototoxicity/ – carcinogenicity remains exciting, as well as not fully elucidated. Nitrosamines remain one of the few reasonable, according to a number of authors, even the only currently directly

Basal cell carcinoma trends in Thailand: a 10-year retrospective study of demographic, clinical and histopathological features

Dermatology Reports, 2021
Background: Basal cell carcinoma (BCC) is the most common skin cancer with globally increasing incidence. To date, the information regarding BCC in Thailand is limited. Objective: To evaluate the demographic, clinical, histopathological trends of BCC and

Creep‐Induced Microstructural Evolution in an A2‐B2 Superalloy

Advanced Engineering Materials, EarlyView.
A 27.3Ta‐27.3Mo‐27.3Ti‐8Cr‐10Al (at.%) refractory high‐entropy alloy with precipitation‐strengthened A2‐B2 microstructure was studied by creep tests at 1030°C, which demonstrate a transition in deformation mechanisms in the range of 100–150 MPa applied stress. This is associated with changes in dislocation–precipitate interactions. Relevant deformation

Basal cell carcinoma of the scalp shows distinct features from the face in Asians

Scientific Reports, 2022
Basal cell carcinoma (BCC) affecting different sites has been reported to have different clinicopathological features. In previous studies, the scalp was commonly classified to the head and neck region.

High‐Temperature Nanoindentation of Metals: Assessing Thermal Drift, Frame Compliance, and Chemical Composition Effects on the Reported Mechanical Properties

Advanced Engineering Materials, EarlyView.
Do not let thermal drift and instrument artifacts deceive high‐temperature nanoindentation results. We compare classical Oliver–Pharr and automatic image recognition analyses across steels and a Ni alloy to quantify these effects. Accounting for artifacts reveals systematic softening with temperature, while Cr and Ni additions boost resistance ...
