Forcing the Side‐on π‐Coordination of a C≡C Triple Bond to Technetium Using the As,CC,As Alkyne Pincer Ligand 1,2‐Bis(2‐(diisopropylarsaneyl)‐4‐(trifluoromethyl)phenyl)Ethyne

Angewandte Chemie International Edition, EarlyView.
Technetium alkyne complexes have eluded isolation for decades with the only indicators for their existence being the isolation of vinylidene carbenes or their follow‐up reaction products despite plentiful of reports for neighboring elements. Stable, crystalline Tc(III) and Tc(V) alkyne complexes (and their Re analogs) have now been prepared and fully ...

Factors Affecting the Slenderness Limit for RC Columns-The Use of the (ACI-318M-05) Provisions

مجلة النهرين للعلوم الهندسية, 2008
The current ACI code and many other codes permit the moment magnification method for design of slender reinforced concrete (RC) columns. Manually, the design/analysis procedure is tedious, so that the codes state a pre-prediction if the column is slender

Scaling of local interface width of statistical growth models

, 2004
We discuss the methods to calculate the roughness exponent alpha and the dynamic exponent z from the scaling properties of the local roughness, which is frequently used in the analysis of experimental data.

From armadillos to sloths: Patterns and variations in xenarthran coronary anatomy

The Anatomical Record, EarlyView.
Abstract Species of the superorder Xenarthra play a vital ecological role in the Neotropics. Despite their evolutionary significance, anatomical studies on their coronary circulation remain scarce. This study investigated the coronary anatomy of 82 hearts from nine Xenarthra species across the Dasypodidae, Myrmecophagidae, and Bradypodidae.

Axial Compression Behavior of Concrete Columns Strengthened with UHPC-Filled Steel Tubes

Buildings
To enhance the load-bearing capacity of conventional reinforced concrete (RC) columns and address the issue of longitudinal reinforcement buckling, this study proposes a novel composite column strengthened with small-diameter ultra-high-performance ...

Paleopathology of a putative colossosaurian caudal vertebra (Neosauropoda: Titanosauria) from the Presidente Prudente Formation, Brazil

The Anatomical Record, EarlyView.
Abstract Studies investigating paleopathologies in sauropods remain scarce despite their relative abundance in the fossil record. In this study we report new occurrence of paleopathological features, corresponding to a neoplasm found in a middle caudal vertebra (MCT.R.2120) of an advanced titanosaur from the Presidente Prudente Formation (Bauru Basin ...

Early stages of tooth development in the harbor porpoise Phocoena phocoena

The Anatomical Record, EarlyView.
Abstract Here we describe the stages of tooth development in toothed whales on the basis of the harbor porpoise (Phocoena phocoena). The aim of the study was to find out whether these stages are identical to those of other mammals analyzed so far although toothed whales are homodont and monophyodont.

Evaluation of a Product Intended for Microbiological Control in Animal Production, and Its Combination With Halquinol

Animal Research and One Health, EarlyView.
Activo Liquid and Halquinol inhibit Salmonella and Escherichia coli in culture media. Activo Liquid exhibits bactericidal action, whereas HA is bacteriostatic, and their combination results in positive or indifferent interactions. This combination effectively inhibits E. coli throughout digestion simulation, thus reducing the required concentrations of
