An Alcohol‐Free SiO2 Sol‐Gel Matrix Functionalized with Acetic Acid as Drug Reservoir for the Controlled Release of Pentoxifylline

Journal of Nanomaterials, Volume 2014, Issue 1, 2014., 2014
Pentoxifylline (PTX) is a xanthine derivative, with hemorrheologic properties, that has been useful in the treatment of several diseases. However, a conventional route of administration implies high doses, what is unnecessary to the organism, seriously increasing the risk of toxicity because of side effects.

Marketization in Public Purchasing as a Route to Business Corporations' Institutional Power: The Case of Outsourcing Social Services in Israel

Policy Studies Journal, EarlyView.
ABSTRACT What are the conditions under which business corporations expand their institutional power? This paper argues that institutional power is affected by the architecture of the “acquisition regime”—the set of formal (and informal) rules that govern how states purchase public services.

Bifurcations in a Generalization of the ZAD Technique: Application to a DC‐DC Buck Power Converter

Mathematical Problems in Engineering, Volume 2012, Issue 1, 2012., 2012
A variation of ZAD technique is proposed, which is to extend the range of zero averaging of the switching surface (in the classic ZAD it is taken in a sampling period), to a number K of sampling periods. This has led to a technique that has been named K‐ZAD. Assuming a specific value for K = 2, we have studied the 2‐ZAD technique.

Building a Non‐Farmhouse: Labor Migration, Construction, and the Decline of Peasant Agriculture in Rural Peru

The Journal of Latin American and Caribbean Anthropology, Volume 30, Issue 4, December 2025.
ABSTRACT This paper examines how residential architecture engages with lifestyles and livelihoods, permitting some activities while foreclosing others. Focusing on houses built by Teodora, her father, and her son in the Peruvian peasant community of Allpachico, I show how experiences of migration paid for and informed the designs of, and materials used

Scaling Non‐Regular Shared‐Memory Codes by Reusing Custom Loop Schedules

Scientific Programming, Volume 11, Issue 2, Page 143-158, 2003., 2003
In this paper we explore the idea of customizing and reusing loop schedules to improve the scalability of non‐regular numerical codes in shared‐memory architectures with non‐uniform memory access latency. The main objective is to implicitly setup affinity links between threads and data, by devising loop schedules that achieve balanced work distribution

Global and Local Shielding/Deshielding Variation in C60 and C70 Fullerenes Upon Reduction: Evaluation of Aromaticity, 13C‐NMR and Anisotropy Patterns

Chemistry – A European Journal, Volume 31, Issue 12, February 25, 2025.
The six‐fold reduction of C60 and C70 fullerenes modifies the magnetic response of the π electrons enabling global and local variations of shielding/deshielding regions along different orientations of the external field which are represented in the variations of 13C‐NMR shifts given by the σ33 shielding component under the principal axis system (PAS ...

Paradigm, experiment and conclusion: La Casa by Bernard Rudofsky in three acts

VLC Arquitectura, 2018
La Casa –or in English, the house– that Bernard Rudofsky built on the Spanish Mediterranean coast in 1971 is a valuable case study on the operational possibilities of popular architecture in the practice of this contemporary discipline.
