Simulated dataset of corn response to nitrogen over thousands of fields and multiple years in Illinois.

Nitrogen (N) fertilizer recommendations for corn (Zea mays L.) in the US Midwest have been a puzzle for several decades, without agreement among stakeholders for which methodology is the best to balance environmental and economic outcomes. Part of the reason is the lack of long-term data of crop responses to N over multiple fields since trial data is often limited in the number of soils and years it can explore.

What determines the success and failure of environmental crowdfunding?

Online crowdfunding can help address the perennial financial shortfalls in environmental conservation and management. Although many online crowdfunding campaigns fail to collect any funds due to not achieving their targets, little is known about what drives success. To address this knowledge gap, we applied a mixed-methods approach to data from 473 successful and failed campaigns hosted on the online crowdfunding platform Readyfor.

Possibility of production of amino acids by impact reaction using a light-gas gun as a simulation of asteroid impacts.

In order to investigate impact production of carbonaceous products by asteroids on Titan and other satellites and planets, simulation experiments were carried out using a 2-stage light gas gun. A small polycarbonate or metal bullet with about 6.5 km/s was injected into a pressurized target chamber filled with 1 atm of nitrogen gas, to collide with a ice + iron target or an iron target or a ice + hexane + iron target.

[A case of pleural effusion in a patient with malignant lymphoma diagnosed by thoracoscopy with local anesthesia].

A 47-year-old woman was admitted for examination of massive right pleural effusion on chest radiography, together with chief complaints of dry cough and body weight loss. Exudative effusion was aspirated by thoracentesis, revealing many lymphocytes and a high level of adenosine deaminase. Thoracoscopy with local anesthesia was performed.
