(2012)α-Cyclodextrin (α-CD) inclusion compounds containing the carboxylic acids (octanoic, decanoic, lauric or dodecanoic, myristic or tetradecanoic, palmitic or hexadecanoic and stearic or octadecanoic) as guests were synthesized ...
-
(2013)The expression of defensive compounds derived from secondary metabolism in plants of Eucalyptus globulus Labill, and the persistence of these in vegetative propagation was evaluated by gas chromatography with flame ionization ...
-
(2013)Following J.D. Murray, we consider a system of two differential equations that models traveling fronts in the Noyes-Field theory of the Belousov-Zhabotinsky (BZ) chemical reaction. We are also interested in the situation ...
-
(2013)We herein report results obtained from an integrated experimental and theoretical study on aromatic nucleophilic substitution (SNAr) reactions of a series of amines towards 1-fluoro-2,4-dinitrobenzene in water. Specific ...
-
(2012)Mussels are one of the most cultivated and commercialized bivalves worldwide and in southern Chile its culture represent an important economic activity. The species identification within the Mytilus genera, by morphological ...
-
(Frontiers Research Foundation, 2012)Water availability is the main limiting factor in arid soils; however, few studies have examined the effects of drying and rewetting on nitrifiers from these environments. The effect of water availability on the diversity ...
-
(2012)Background: Sonic hedgehog (Shh)/Gli pathway plays an important regulatory role on the neuroepithelial cells (NEc) proliferation in the dorsal regions of the developing vertebrate Central Nervous System. The aim of this ...
-
(2013)The dynamics of the collision process of a titanium dimer against a C 20 nanocluster in the bowl configuration is simulated by means ab initio molecular dynamics, focusing our interest on the first steps to synthesize ...
-
(Sociedad Chilena de Quimica, 2012)The diene Erythrina alkaloids erysotrine (1), erysodine (2), erythraline (3), erytharbine (4), and erysotrine N-oxide (5), plus the hydroxylated dihydro derivative of 1, epierythratidine (6) were isolated from seeds of ...
-
(2013)Diels-Alder cycloaddition of 8,8-dimethylnaphthalene-1,4,5(8H)-trione with diastereomeric hydroxysulfinyldienes proceeded with high yields and good π-facial and regioselectivities. The hydroxysulfoxide moiety controls the ...
-
(2012)The need for conservation outside protected areas has prompted the modifi cation of productive practices to allow the maintenance of wild biota in productive landscapes such as those associated to timber production. Forest ...
-
(2012)A local measure of the electrophilicity has been recently proposed to analyze the chemical reactivity of several kinds of molecules. In this work a theoretical rationalization of the local extension is proposed following ...
-
(2013)Megacities are not only important drivers for socio-economic development but also sources of environmental challenges. Many megacities and large urban agglomerations are located in the coastal zone where land, atmosphere, ...
-
(2012)In nucleophilic substitution reactions at carbonyl centres, there are two possible channels. The first one occurs when the attack of nucleophilic agents takes place simultaneously with the departure of the nucleofuge. This ...
-
(Academic Press, 2013)Wooden snuff trays from San Pedro de Atacama (SPA) in northern Chile are objects of particular museological value. Computed tomography (CT), a non-destructive analytical technique useful in the analysis of archaeological ...
-
(2012)The effect of the disturbances caused by the American beaver (Castor canadensis), introduced to the Cape Horn Biosphere Reserve, on species of birds that are forest habitat specialists is poorly understood. Using telemetry ...
-
(2013)Modern pinnipeds distributed along the coasts of continental South America consist almost entirely of otariids (sea lions and fur seals). In contrast, phocids (true seals) are present only on the southernmost extreme of ...
-
(2012)Background:Aloe vera, a plant with crassulacean acid metabolism naturally adapted to water deficit, was introduced in the semi-arid regions of Chile in 1999.Aims: Our objective was to evaluate how A. vera scavenged the ...
-
(AOAC International, 2012)The method was approved by the Expert Review Panel on Strategic Foods Analytical Methods as First Action. See "Standards News," (2012) Inside Laboratory Management, March/April issue. The AOAC Stakeholder Panel on Strategic ...
-
(Oxford University Press, 2012)Plants' developmental plasticity plays a pivotal role in responding to environmental conditions. One of the most plastic plant organs is the root system. Different environmental stimuli such as nutrients and water deficiency ...
