Auctions with endogenous participation and quality thresholds : evidence from ODA infrastructure procurement [PDF]
Infrastructure projects are often technically complicated and highly customized. Therefore, procurement competition tends to be limited. Competition is the single most important factor toward auction efficiency and anti-corruption. However, the degree of

Advanced Science, EarlyView.An acid‐responsive core‐shell microneedle system normalizes the degenerative annulus fibrosus microenvironment by consuming pathological H+, generating O2, and providing NIR‐amplified redox buffering. Mechanistically, it epigenetically suppresses ferroptosis via DNMT3A‐dependent methylation of the ATF3 promoter, relieving ATF3‐mediated repression of ...

Administrative protection of participants in the procedure of public procurement under Croatian law
Zbornik Radova Pravnog Fakulteta u Splitu, 2011 Public procurement in Croatia was legislatively regulated for the first time in 1997. The system for administrative protection of the participant rights in public procurement was only established in 2001.

In Situ CO2‐Induced Hydrogels for Enhancing Carbon Sequestration in Saline Aquifers
Advanced Science, EarlyView.A novel integrated method that combines in situ CO2‐induced phase‐transition hydrogels formed by a C22‐tailed tertiary amine dispersion with tailored deep eutectic solvents to increase CO2 sequestration in saline aquifers. ABSTRACT Carbon sequestration in saline aquifers underpins global net‑zero emission goals, yet existing CO2 storage capacity ...

Corruption risk factors: an analysis of public procurement in Nigeria [PDF]
Nigeria has consistently ranked 6th amongst oil-producing nations of the world but despite the enormous revenues from the sale of petroleum resources in the past five decades, the country has made little advance in terms of infrastructure, quality of ...

What factors influence the uptake of GPP (Green Public Procurement) practices? New evidence from an Italian survey [PDF]
Green Public Procurement (GPP) is becoming a cornerstone of environmental policies both at European Union and Member State level. Drawing upon a database of public authorities located in three Italian Regions, this paper assesses the determinants and ...

Advanced Science, EarlyView.An advanced, long‐term human skin platform maintains native skin structure and key tissue functions for up to four weeks. The platform models chronic inflammation, aging‐related skin changes, and UVB damage, enabling drug and topical interventions—including anti‐inflammatory therapy, senolytic treatment, and sunscreen—to be evaluated in intact human ...

Advanced Science, EarlyView.Incomplete microwave ablation induces animmunosuppressive microenvironment in tumor‐draining lymph nodes. An albumin‐based lipoprotein nanosystem enables coordinated delivery of immunomodulators to tumor‐draining lymph nodes and residual tumors, reverses post‐ablation immunosuppression, suppresses residual tumor growth, and promotes durable antitumor ...
