Interoperability Between Mobile Money Agents and Choice of Network Operators: The Case of Tanzania.

In this paper, we investigate the effects of non-exclusive agreements between networks of mobile money agents on mobile network operator choices, using survey data from Tanzania conducted in 2017. By combining survey responses with geo-location data and information on agent proximity, we employ discrete choice models to analyze consumers' decisions in subscribing to mobile network operators and their corresponding mobile money providers. Our findings highlight the significant influence of the distance to mobile money agents on consumers' subscription choices.

Glycerolysis of Poly(lactic acid) as a Way to Extend the "Life Cycle" of This Material.

The article concerns the use of glycerolysis reaction as an alternative method of processing post-production and post-consumer waste from poly(lactic acid) (PLA). Management of waste is a very important issue from an environmental protection and economic point of view. Extending the "life cycle" of PLA is extremely important because it allows to make the most of this material.

Evaluation of the impact of soil contamination with mercury and application of soil amendments on the yield and chemical composition of L.

The purpose of this study was to determine the effect of soil contamination with Hg on the yield and chemical composition of L. Mercury was incorporated into soil in amounts: 0, 50, 100 and 150 mg Hg·kgof soil. Zeolite, lime and bentonite were used to alleviate the soil contamination.
