Biodegradable Wireless Soil Urea Sensor Using Metamaterial Perfect Absorber for Distributed Deployment in Precision Agriculture

open access: yesAdvanced Materials Technologies, EarlyView.
In this study, we propose a biodegradable wireless soil urea sensor for precision agriculture. The sensor's electromagnetic response varies depending on the urea concentration, allowing the measurement of relative soil urea concentrations by analyzing the time‐transient electromagnetic response.

Red Fluorescent Protein‐Metal Organic Framework Hybrids for Lighting Applications

open access: yesAdvanced Optical Materials, EarlyView.
We demonstrate the encapsulation in a metal‐organic framework (MOF) of two red fluorescent proteins, DsRed and mCherry. The materials conserve all spectroscopical and structural properties of the underlying components, which allows for their implementation as color down‐converting materials in bio‐hybrid light‐emitting diodes, which exhibit average 3 ...

The association between working hours and working type with non-alcoholic fatty liver disease: results from the NHANES 1999-2014

open access: yesFrontiers in Endocrinology
BackgroundPrevious research has indicated that long working hours are connected to a variety of health conditions, including nonalcoholic fatty liver disease (NAFLD). However, this association which has been observed in more population is limited.

Elimination of Necking and Aspect Ratio Dependence in Uniaxial Actuators by Continuous Fiber Reinforcement

open access: yesAdvanced Robotics Research, EarlyView.
A novel carbon fiber reinforcement for dielectric elastomer actuators enhances actuation force while decoupling electromechanical performance from the actuator's aspect ratio. Unlike conventional fiber reinforcements, it enables a uniform planar stretch state along the entire actuator.

Lifecycle deficit and economic support ratio in Nigeria: The national transfer account approach

open access: yesJournal of Economics and Management
Aim/purpose – The benefit of changing the population age structure only accrues to an economy if the labor market absorbs the increasing number of the working population at a given labor income that surpasses the prevailing consumption of that age group.

Labor Standards and Trade Agreements [PDF]

open access: yes
There is a wide disparity of views on issues of international labor standards. Labor and social activists are concerned about the increased imports from countries in which labor standards are ostensibly not enforced at a sufficiently high level.

Auto‐Routing Fluidic Printed Circuit Boards

open access: yesAdvanced Robotics Research, EarlyView.
This work introduces (STREAM) software tool for routing efficiently advanced macrofluidics, an open‐source software tool for automating the design of 3D‐printable fluidic circuit boards. STREAM streamlines tube routing and layout, enabling the rapid fabrication of fluidic networks for soft robotics, lab‐on‐a‐chip devices, microfluidics, and biohybrid ...

The feasibility of working time reductions: labor market segmentation by practical work conditions

open access: yesSustainability: Science, Practice and Policy
Generalized claims regarding the feasibility of working time reductions (WTRs) dominate academic and public discourse. Beyond sporadic acknowledgements of the diversity of work contexts illustrated only by isolated examples, no attempts have been made to segment the workforce by the conditions that influence why and how WTRs can be implemented. This is
