The role of venture‐financed startups in innovation for US agriculture

American Journal of Agricultural Economics, EarlyView.
Abstract To evaluate the role played by startup companies in the innovation ecosystem of US agriculture, we compile a unique dataset of 6024 new entrants founded 1987–2019 that details their financing lifecycles, annual economic performance, and patenting activities.

Catalytic Pyrolysis of Waste Polystyrene Over Fe–B Composite Catalyst for Enhanced Liquid Fuel Production

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Healthcare derived polystyrene waste represents a growing and under addressed fraction of plastic waste streams due to contamination risks and limited recyclability. This study aims to investigate the valorization of waste polystyrene foam through catalytic and noncatalytic pyrolysis pathways to evaluate product yield distribution and identify

Soil reaction to lateral harmonic pile motion

, 2016
The analytical representation of dynamic soil reaction to a laterally-loaded pile using 3D continuum modeling is revisited. The governing elastodynamic Navier equations are simplified by setting the dynamic vertical normal stresses in the soil equal to ...

Synergistic Advanced Oxidation and Physicochemical Treatment Strategies for Antibiotic Removal and Resistance Mitigation in Water

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The presence of antibiotics in water not only causes environmental pollution but also increases the growth of antibiotic‐resistant bacterial genes, which pose serious threats to human beings and other water residents. Large numbers of people are reportedly affected by the resistant bacterial genes, as many broad‐spectrum antibiotics are not ...

Additives Enhancing Biodegradability in Plastics and Potential Implications for Textiles: A Mechanistic Review

Journal of Applied Polymer Science, EarlyView.
Mechanistic insights from additive‐assisted plastic degradation guide the design of environmentally adaptive textile fibers. Functional additives enhance oxidative, hydrolytic, enzymatic, and microbial degradation pathways. Translating these strategies requires control of fiber architecture, additive distribution, and environmental interactions ...

Analysis of Bearing Characteristics of the Static Drill Rooted Nodular Piles Under Tension and Compression

工程科学与技术, 2018
The static drill rooted nodular pile is a kind of composite pile foundation by inserting the prefabricated nodular pile into the cemented soil. The FEM models of the PGPN (pre-bored grouting planted nodular) pile under compression and tension were ...

Enabling the study of gene function in gymnosperms: Virus‐induced gene silencing in Ephedra tweedieana

Applications in Plant Sciences, EarlyView.
Abstract Premise As the sister clade to angiosperms, extant gymnosperms are crucial for reconstructing ancestral gene regulatory networks in seed plants. This highlights the need for model systems representing each of their distinct lineages. However, tools to quickly and effectively investigate gene function in gymnosperms are still limited due to the

Poseidon's Sanctuary at Samikon—The Discovery of an Ancient Temple Through an Integrated Geophysical and Geoarchaeological Survey Approach for Lagoonal and Swampy Environments

Archaeological Prospection, EarlyView.
ABSTRACT Below the classical fortress of Samikon at the coast of the western Peloponnese, ancient writer Strabo mentioned a sanctuary of Poseidon which served as the centre of the religious association of the Triphylian cities. In this paper, we describe the discovery and investigation of a building structure by means of geophysical and ...
