3D‐Printing Aided Rapid Prototyping of Pretensioned Tensegrity Structures for Robotic Applications
Advanced Robotics Research, EarlyView.Printing, injection molding, and assembly (PMA) is a method for rapid prototyping mesoscale, topologically complex, and tensioned tensegrity structures. In combination with PMA method, two mold design strategies: modular mold and compact channel layout, enable efficiency and scalability for tensegrity fabrication.

Can we produce more beef without increasing its environmental impact? Argentina as a case study
Perspectives in Ecology and Conservation, 2020 We analyse the current and future environmental impact of beef in Argentina, comparing four environmental dimensions (GHG, ecotoxicity, erosion and biodiversity) across 21 cow-calf systems and 47 finishing systems.

Advanced Science, EarlyView.Fluorescent BODIPY‐conjugated thiosemicarbazone ligands and their Ga(III), In(III), and Fe(III) complexes, inspired by Triapine, are developed as theranostic agents. Multiphoton FLIM and confocal microscopy in cancer cells and zebrafish reveal real‐time uptake, mitochondrial localisation, and whilst spectroscopic assays indicated preserved complex ...

FACTORS AFFECTING THE ADOPTION OF VALUE-ADDED PRODUCTION ON COW-CALF FARMS [PDF]
Factors that affect the decision to feed or sell calves at weaning are analyzed for Arkansas cow-calf operators. A discrete choice logit model is used to analyze the adoption of value-added cattle production.

Preventing Perinatal Beef Calf Mortality [PDF]
, 2011 Perinatal calf mortality (PCM) refers to death loss from the time of calving through the first month of life. Previous USDA estimates put this loss at over 2.7 million calves ($976 million) annually, with nearly 70 percent coming within four days of ...

Advanced Science, EarlyView.Corramycin, a myxobacterial natural product antibiotic, exhibits potent bactericidal activity against multidrug‐resistant Mycobacterium tuberculosis. The compound hijacks bacterial transporters such as BacA and OppABCD to enter the cell and inhibits DNA synthesis through a previously unrecognized mode of DNA gyrase poisoning, locking the enzyme in an ...

The Diverse Structure and Organization of U.S. Beef Cow-Calf Farms [PDF]
Beef cow-calf production in the United States is widespread, occurring in every State. Nearly 765,000 farms, about 35 percent of the 2.2 million farms in the United States, had a beef cow inventory in 2007. Most of these were small, part-time operations.
