in calcareous soils with high calcium carbonate contents and ph, the growth and development of plant might undergo nutritional disorders. the process of biological nitrogen fixation in legumes cultivated and plant growth in these soils could be limite. the use of acid-producing materials like sulfur and a reduction in soil ph improves plant growth and increase the biological nitrogen fixation. ...

maximum 150 words) This study aims to expand current understanding of ideation methods and its transferability from the physical domain (product) to the transactional domain (services). It evaluates the impact of two Design-by-Analogy (DbA) ideation methods (WordTree and SCAMPER) in both, creativity and design fixation management when solving transactional design problems. These results are con...

background: no uniform consensus exists to decide type of fixation for arthroscopic anterior cruciate ligament reconstruction. hypothsis: there is similar functional outcome after rigid fix compared to other methods of fixation which has been published. study design: retrospective observational study. methods: a total of 50 patients underwent arthroscopic anterior cruciate ligament reconstructi...

Shoulder arthroplasty represents one of the fastest growing orthopaedic procedures in the USA. In comparison to hemiarthroplasty, total shoulder arthroplasty has higher patient satisfaction and lower revision rates. Aseptic glenoid loosening remains a concern for longevity of total shoulder arthroplasties. Cement fixation on the glenoid side represents the primary and only mode of fixation in t...

The hydrogen bond donor-promoted fixation of CO(2) and epoxides into cyclic carbonates was investigated through experimental and density functional theory studies. A highly effective homogeneous system of 1,2-benzenediol-tetrabutyl ammonium bromide (TBAB) and heterogeneous poly-ionic liquids were developed for the fixation of CO(2) into cyclic carbonates via hydrogen bond activation, based on t...

This study compares the functional capabilities of different metacarpal fixation constructs under physiological loadings in an attempt to identify the optimal construct rather than the strongest one. One hundred and twenty-six preserved human metacarpals were mechanically tested after oblique osteotomies and internal fixation. Maximum load to failure, average structural rigidity, and energ...
