Abstract: the elimination of burning practices in sugarcane harvest has led to more sustainable productive systems, with lower impact on the environment and on communities. the present paper is part of a study in which two sugarcane management systems were compared: (a) one with sugarcane harvest residue kept on the ground (trash blanketing); and (b) one without trash blanketing (burnt residue). cultivar lcp 85-384 was planted in macro-plots in a commercial field in albarracín, tucumán, argentina. a split-plot experimental design with three replications was used. each plot had five 30 m-long rows. two crop cycles (2006/2007 and 2007/2008), i.e. second and third ratoon, were evaluated. from the end of harvest onwards, residue amount (dry matter/ha) and residue c/n relationship were determined periodically. at the beginning and at the end of each crop cycle, residue p and k contents were assessed. residue left after harvest amounted to 12 and 16 tons of dry matter per hectare in the first and second evaluated crop cycles, respectively, but decreased significantly throughout these periods. residue c/n relationship was over 100 in both crop cycles (117 and 101, respectively), but decreased significantly in their course. reductions in both sugarcane residue and c/n relationship were correlated with days after harvest and accumulated thermal time (∑ mean daily air temperature). trash initial c concentration was similar in both crop cycles and amounted to approximately 45%, whereas initial n concentration differed (0.4% and 0.6% in second and third ratoon, respectively). residue decomposition contributed 3800 to 5700 kg of c, 7 to 50 kg of n and 45 to 40 kg of k per ha to the agro-ecosystem in both crop cycles studied.
Lidocaine-Induced Cell Growth of Human Gingival Fibroblasts. Role of Na+-K+-ATPase and PKC Activities  [PDF]

Pharmacology & Pharmacy (PP) , 2014, DOI: 10.4236/pp.2014.58090
Abstract:

Background: Evidences have shown that local anaesthetics are clinically useful compounds that exert a pharmacological effect by blocking nerve impulse propagation and also it is able to provoke proliferation and cell growth. Aims: The aim of this study was to investigate the proliferation and cell growth capacity of lidocaine on human gingival fibroblast cells and the different signal pathways involved in its effect. Method: For this purpose in vitro cultures of human gingival fibroblasts were assayed and the effects of lidocaine on proliferation and cell DNA synthesis, Na+-K+-ATPase and PKC activities and K+ efflux were also evaluated. Results: Lidocaine stimulated in a concentration-dependent manner proliferation and cell growth of human gingival cells and the mechanism involve an increment in Na+-K+-ATPase and PKC activities, which led to an increase in K+ release. All of these effects were blocked by tetrodotoxin, ouabain and calphostin C. In addition, PMA (activator of PKC)

Las escuelas de los profetas
Francisco Quinteros del águila
Apuntes Universitarios , 2013,
Abstract: The author explores the relationship between current education and schools of the prophets as an educational model. This is part of a historical study to identify the schools of the prophets in the Bible and in the writings of Ellen White. This paper proposes a reflection on christian education from a biblical platform, which provides for a spirit of deep christian devotion and the teachers, the relationshipof the study and work as a distinctive feature of the student as well as personalized tutorial attention, which is equivalent to an educational model that well would forceteachers and administrators to imitate.
Los genoveses, el adelantado Pedro Fajardo y Enrique IV: comercio, fraudes y ambiciones territoriales en el Reino de Murcia (1454-1474)
Quinteros Cortés, Javier
Anuario de Estudios Medievales , 2011,
Abstract: This article analyzes the exceptional privileges that Governor Pedro Fajardo and the City Council of Murcia granted to the Genoese merchants between 1454 and 1474, mostly to the Negro and Spínola families, to import and export products to and from the other extreme of the border of the Kingdom of Granada, with guaranteed insurances for the incomes of the city. This security proves an absence of danger in the commercial transit in the coasts of Granada and challenges the idea of rivalry between the Governor and the king of Granada formulating a new hypothesis: a mercantile alliance between both ringleaders that protected the Kingdom of Murcia of an economic blockade on the part of Castilian king Henry IV after the conflict with the unsuccessful Alphonso XII. El presente artículo analiza los excepcionales privilegios que el Adelantado Pedro Fajardo y el Concejo de Murcia concedieron a los mercaderes genoveses entre 1454 y 1474, principalmente a las familias Negro y Spínola, para importar y exportar productos desde y hacia el otro extremo de la frontera del Reino de Granada, con seguros avalados con las rentas de la ciudad. Esta seguridad en el tránsito comercial demuestra una ausencia de peligro en las costas granadinas que pone en entredicho la idea de rivalidad entre el Adelantado y el rey de Granada formulando una nueva hipótesis: una alianza mercantil entre ambos cabecillas que protegía al Reino de Murcia de un bloqueo económico por parte del rey Enrique IV tras el conflicto con el fallido Alfonso XII.

A morphology-based phylogeny of Phymaturus (Iguania: Liolaemidae) with the description of four new species from Argentina
Lobo, Fernando;Quinteros, Sebastián;
Papéis Avulsos de Zoologia (S?o Paulo) , 2005, DOI: 10.1590/S0031-10492005001300001
Abstract: phylogenetic relationships within the liolaemid lizard genus phymaturus were studied using parsimony analysis of morphological data. the data set includes 133 characters: 28 described in the literature as apomorphies of the three genera of liolaemidae (ctenoblepharys, liolaemus, and phymaturus), 21 published characters of allozymes and karyology, 53 characters taken from external morphology across all terminals of phymaturus, and 31 from the skeletal anatomy. this data set includes representatives of 10 of the 12 species currently recognized in the literature plus twelve other terminals considered in this study and representing independent lineages assigned to patagonicus or palluma. four of these terminals are described in the present study as new species, one belonging to the palluma group and the other three to the patagonicus group. we performed four analyses using different methods of coding binary polymorphic characters, and a new method for treating continuous characters. the traditional division of the genus in two groups is not supported here, with the patagonicus group resulting paraphyletic in some of the analyses. the palluma group is monophyletic and supported by many characters. a majority rule consensus tree of all runs recovers a reasonably well-resolved topology of the group. all analyses recovered a northern subclade within the palluma group, formed by species distributed in argentina from northern of san juan province (north to 30 degrees of latitude). in this analysis palluma from el planchón (chile) was found to be more closely related to this northern subclade than any other "palluma" form.
