Sustainable Productivity Growth in Agriculture: The Role of Shifts in R&D Investments and Technology

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT The objective of the paper is to evaluate the long‐term prospects of sustainable productivity growth linked to plausible assumptions on public agricultural R&D investments as the key productivity driver. Second, it investigates the role of changing R&D focus from yield maximization to input saving technologies (fertilizers and pesticides). The

Experimental Investigation on Rubberized Concrete Mixed Proportion Design [PDF]

, 2011
The rubber powder, mesh 20,40,60 and 80, were mixed into comparison plain concrete by the volume contents of 50,75,100 and 125 L/m3 of the aggregates, to make rubberized concrete. The specimen compressive strength is examined.

A new cyclic model for FRP ‐confined rubberized concrete [PDF]

, 2022
This article proposes a new constitutive model for the cyclic behavior of rubberized concrete confined with fiber-reinforced polymer (FRP) sheets. The model is calibrated with experimental results from 18 confined rubberized concrete (CRuC) cylinders ...

Rubber concrete: Mechanical and dynamical properties

Case Studies in Construction Materials, 2018
The purpose of this paper is to report on an experimental study that explores the effect of using recycled rubber powder as an alternate fine aggregate in concrete mixes. Natural sand in the concrete mixes was partially replaced by 5%, 10%, 15%, and 20%.

Mechanical properties of rubberized concrete using truck scrap rubber

Materials Today: Proceedings, 2021
Abstract Concrete is becoming most widely used construction material owing to its versatility and dynamic nature of adopting addition of any admixture into it. Numerous research works were being undertaken by several researchers across the globe to study the inherent nature of concrete with and without various admixtures, replacement agents and ...

Accounting for animal health in efficiency analysis: An application to Swedish dairy farms

American Journal of Agricultural Economics, EarlyView.
Abstract Poor animal health is a central concern in modern livestock production. Despite the necessity to incorporate animal health in efficiency analysis, the theoretical and empirical developments are limited on this subject. This article appropriately characterizes the axiomatic properties of animal health within a production framework.
