Using the example of our own work about astronomies in the Argentinian Chaco, we show the fruitfulness of a regional approach to ethnoastronomical studies. Our interest is to highlight the relevance of thinking the astro...

Purple carrots (Daucus carota ssp. sativus var. atrorubens Alef.) accumulate anthocyanins in their roots, petioles and other plant parts. These flavonoid pigments represent an excellent dietary source of antioxidant and ...

Among the South American Arid Diagonal (SAAD), the Argentine Arid Diagonal (AAD) constitutes an area with low precipitations (less than 500 mm) and extends from the north of the country (on the border with Bolivia), to P...

This work presents the initial steps for the development of a serious game aimed at training users of upper limb prosthesis. In this initial phase, a virtual environment consisting of a soccer stadium was developed using...

Beyond the unique sound of howler monkey vocalizations, their vigorous loud calling displays are perplexing given the otherwise sedentary lifestyle of these primates. Here we provide potential explanations for this energ...

Hunting and gathering remained the main mode of subsistence of humanity for hundreds of thousands of years, beginning some 1.8 million years ago, and until the Neolithic Revolution (some 10,000 years ago), when agricultu...

Intracellular levels of cyclic nucleotide second messengers are regulated predominantly by a large superfamily of phosphodiesterases (PDEs). Most of the different PDE variants play specific physiological functions; in fa...

Population coding is the quantitative study of which algorithms or representations are used by the brain to combine together and evaluate the messages carried by different neurons. Here, we review an information-theory b...

Heteroduplex-based genotyping methods have proven to be technologically effective and economically effi cient for low- to medium-range throughput single-nucleotide polymorphism (SNP) determination. In this chapter we des...

Layer-by-layer (LbL) self-assembly microencapsulation is a promising method to protect and deliver probiotics, although its implementation has mostly been confined to the lab scale. This study develops a scalable method ...

Refractories are defined as "non-metallic materials having those chemical and physical properties that make them applicable: for structures, or as components of systems, that are exposed to environments above 1,000 °F (...

The cities of arid North Patagonia are located mainly on valleys framed by slopes. In recent decades they have had exponential demographic growth. The unplanned expansion of the urban area occurs over sensitive and poten...

Capybaras (Hydrochoerus hydrochaeris) have been used in Argentina since pre-Columbian times as a source of hide, meat, and fat. Hide is the most valuable capybara by-product and, at present, represents the major hunting ...

The philosophy of neuroscience has been a dynamic field of research in the philosophy of science since the turn of the century. As a result of this activity, a new mechanistic philosophy has emerged as the dominant appro...

Cloud computing is a business paradigm, where cloud providers offer resources (e.g., storage, computing, network) and cloud consumers use them after accepting a specific service level agreement. Cloud requirements can ra...

A key characteristic of most woody bamboos is the process of cyclical flowering after a long vegetative period. These flowering events are generally gregarious, affecting an entire region, and are followed by the death o...

Brood reduction is a within-brood partial mortality due to sibling rivalry and has been observed in a large number of bird species from diverse taxa. Here, I summarize several hypotheses accounting for the adaptive value...

Metabolism of Rhodococcus has evolved for adapting to a wide range of nutritional conditions. This adaptation often involves the flexibility of the central metabolism, which usually provides energy and precursors for bio...

The Península Valdés region is situated in an intraplate position of the South American Plate, in the Patagonian foreland close to the Argentine Continental shelf. This region has a complex geotectonic evolution that s...

This chapter explores the relationship between cultural (e.g., utilitarian), psychological (e.g., prominence and ease of observation), and organoleptic factors (e.g., taste perceptions) related to the use of stingless be...

The last important –and possibly the most spectacular– turnover in South American mammal history occurred around the Pleistocene-Holocene boundary, when 100% of megamammal species and about 80% of large mammal specie...

Membrane transporters play a central role in protecting the body from xenobiotics (either by preventing their absorption, limiting their distribution, or promoting their elimination). Transporters can also participate in...

During the last years, microorganisms (yeasts, fungi, microalgae and bacteria) have been receiving increasing attention as alternative lipid sources (also called single cells oils). Some lipid-accumulating bacteria, in p...

In this article we describe the application of lipases in acylation and alcoholysis reactions on steroids and nucleosides. In the field of steroids, a variety of acetyl and fatty acid derivatives of androstanes, pregnane...
