Sonochemical Functionalization of Glass
Advanced Functional Materials, EarlyView.A new method for functionalizing glass using ultrasonication of aryl diazonium salts. Aryl radicals generated by ultrasounds react with glass, forming a stable, covalently bonded organic film. The functionalized glass adheres microorganisms such as microalgae, fungi, and bacteria, suggesting potential applications in enzyme production, filtration ...

Do smaller chicken farms use more antibiotics? Evidence of antibiotic diffusion from Nigeria
Agribusiness, Volume 39, Issue 1, Page 242-262, Winter 2023., 2023 Abstract Farmers across the world have been using antibiotics in poultry production for both therapeutic and nontherapeutic purposes since the mid 1900s. The literature on antibiotic diffusion and intensification is largely focused on developed countries in North America and Western Europe.

On Changes of Global Wet-bulb Temperature and Snowfall Regimes [PDF]
arXiv, 2019 To properly interpret the observed shrinkage of the Earth's cryosphere it is important to understand global changes of snowfall dominant regimes. To document these changes, three different reanalysis products of wet-bulb temperature together with observationally-based data sets are processed from 1979 to 2017.

FMI Compliant Approach to Investigate the Impact of Communication to Islanded Microgrid Secondary Control [PDF]
arXiv, 2017 In multi-master islanded microgrids, the inverter controllers need to share the signals and to coordinate, in either centralized or distributed way, in order to operate properly and to assure a good functionality of the grid. The central controller is used in centralized strategy.

, 2021 Central Peripheries explores post-Soviet Central Asia through the prism of nation-building. Although relative latecomers on the international scene, the Central Asian states see themselves as globalized, and yet in spite of – or perhaps precisely because of – this, they hold a very classical vision of the nation-state, rejecting the abolition of ...

Advanced Functional Materials, EarlyView.In this article, a water‐evaporation driven energy harvester is devised that works even in the absence of sunlight. This is achieved by combining PVA hydrogel with thermoelectrics (TEG) to directly capture energy from water evaporation. Under mild conditions (RH 40%, T of 26 °C, and 2.8 m s−1 wind), 1.71 mW (1.02 W m−2) power can be generated, >3 fold ...

Constructing Market-based Economies in Central Asia: A Natural Experiment? [PDF]
The European Journal of Comparative Economics, 2010 This paper reviews the experience of the five Central Asian countries in the two decades since independence. In the 1990s the five countries looked like a natural experiment. They had similar initial conditions, but different transition strategies. Today
