This letter describes the one-step conversion of heteroatom-substituted potassium organotrifluoroborates (KRBF) to metal monoorganoborohydrides (MRBH) using alkali metal aluminum hydrides. The method tolerates a variety of functional groups, expanding MRBH diversity. Hydride removal with MeSiCl in the presence of dimethylaminopyridine (DMAP) affords the organoborane·DMAP (RBH·DMAP) adducts.

As aluminum high-speed multi-hulls continue to grow in size, capacity and operational sea state, a need is growing to understand the damage tolerance of these structures. This paper presents a Linear Elastic Fracture Mechanics (LEFM) approach to performing damage tolerance assessments of aluminum hull structures using the hydrodynamic analysis and global finite element model developed as part of a class Dynamic Loading Approach (DLA) notation. The LEFM approach is used to calculate the stress intensity factor (K) and the critical crack length throughout the model to screen the entire hull structure and identify fracture critical locations. This paper also investigates the use of elastic-plastic fracture mechanics to predict potential critical crack growth locations, rates, and directions. Fracture critical locations identified and visualized through the analysis provide the ship designer with tools to develop damage tolerant structures. The results of the analysis can also assist owners and regulatory bodies in developing structural inspection and repair plans.

In India, the majority of people believe that any form of mass media can reflect society. Advertising is one of the most important and influential media products. Advertisements (Ads) are known for being convincing, particularly television ads, which are thought to be the most successful kind of mass-market advertising. Advertising serves as a critical agent of socialization in modern developed societies and is used to maintain specific social structures. The current research article uses discourse analysis to examine how the idea of women's employment is presented in selected Indian television commercials. This study primarily focuses on the use of language in advertisements that are used to control people's thoughts. After analysis, it was found that when the majority of household advertisements, label women in a subordinate position, some brands challenge these stereotypes. The storylines focused on women's empowerment are receiving a warm reception from society. Advertisements that portray women positively have more chances of success, making the brand unique and standing out among the mass.
