Análisis AFLP de variación somaclonal en embriones somáticos de Hevea brasiliensis
Medina,Claudia; García,Ibonne; Caro,Marina; Aristizábal,Fabio A;
Revista Colombiana de Ciencias Químico - Farmacéuticas , 2007,
Abstract: the somaclonal variation is an event that can appear during the in vitro vegetal tissues cultures as genetic modifications in cells and tissues. this variation has been used in processes of genetic improvement and to increase the natural genetic variation. nevertheless, when the purpose is the clonal propagation, like rubber tree micropropagation case by somatic embryogenesis, somaclonal variation is an unwanted phenomenon. this research established a methodology for somaclonal variation detection using aflp molecular markers in hevea brasiliensis somatic embryos of the clones ian 710 and ian 873 and plantlet donors of leaves for the process of somatic embryogenesis was used. this robust technique reliable allow showed variation within donating plants, and a high rate of somaclonal variation within embryogenic calluses of hevea brasiliensis , likewise, showed high variation among embryogenic calluses and plantlet donors
Conflito ambiental em águas costeiras: rela??o porto - cidade no Canal de S?o Sebasti?o
Cunha, ícaro;
Ambiente & Sociedade , 2003, DOI: 10.1590/S1414-753X2003000300006
Abstract: the text describes environmental conflicts related to the uses of water in s?o sebasti?o marine channel. this natural port in s?o paulo's north coast supports the biggest petroleum terminal in latin america as well as activities of a cargo harbor. it also discusses the relations between city and port based on authors who analyse coastal cities and environmental conflicts issues in search of new possibilities to sustainability construction.
IDENTIDADES JUDíAS CONTEMPORáNEAS EN AMéRICA LATINA
CARO,ISAAC;
Atenea (Concepción) , 2008, DOI: 10.4067/S0718-04622008000100006
Abstract: in this paper, we refer to jewish latin american identities, defining four central models, independently of whether they are mutually exclusive or not. the first two models are mainly based on ethnic and cultural differences, and the other two are founded on religious and theological divergences. we argue that these different models -some of them opposite and contradictory- present a heterogeneous and mixed mosaic of cultural and religious identities, leading to a fifth model, characterized by the emergence of new identities.
Enfermería: Integración del cuidado y el amor. Una perspectiva humana
Caro,Sarita;
Revista Salud Uninorte , 2009,
Abstract: nursing as a discipline aims towards integral care, taking into account professional and disciplinary elements. jean watson suggests in her theories to include humanized care when it comes to look after patients.
Identidades Islámicas Contemporáneas en América Latina
Caro,Isaac;
Universum (Talca) , 2007, DOI: 10.4067/S0718-23762007000200003
Abstract: in this paper, we examine four "latin american islam" models. first, the configuration of muslim communities in the caribbean: the "indo-asiatic islam". second, the formation, in south american countries, ofan "arabic islam". third, the "new muslims", through a conversion process to islam. finally, the presence of a radical islamism. we postulate that the diversity that characterizes islam and islamism is related also with latin america, through the conformation of some models that are diverse and antagonist in some cases
Generalized sum-free subsets

International Journal of Mathematics and Mathematical Sciences , 1990, DOI: 10.1155/s016117129000103x
Abstract: Let F={A(i):1 ¢ ‰ ¤i ¢ ‰ ¤t, t ¢ ‰ ¥2}, be a finite collection of finite, pairwise disjoint subsets of Z+. Let S ¢ R{0} and A ¢ Z+ be finite sets. Denote by SA={ ¢ ‘i=1asi:a ¢ A, Si ¢ S, the si are not necessarily distinct}. For S and F as above we say that S is F-free if for every A(i), A(j) ¢ F, i ¢ ‰ j, SA(i) ¢ SA(j)= .
A linear upper bound in zero-sum Ramsey theory

International Journal of Mathematics and Mathematical Sciences , 1994, DOI: 10.1155/s0161171294000864
Abstract: Let n, r and k be positive integers such that k|(nr). There exists a constant c(k,r) such that for fixed k and r and for every group A of order kR(Knr,A) ¢ ‰ ¤n+c(k,r),where R(Knr,A) is the zero-sum Ramsey number introduced by Bialostocki and Dierker [1], and Knr is the complete r-uniform hypergraph on n-vertices.

Decline of large mammals in the Katavi-Rukwa ecosystem of western Tanzania
Tim Caro
African Zoology , 2011,
Abstract: In the Katavi-Rukwa ecosystem of western Tanzania, aerial censuses carried out between 1988 and 2002 show that populations of several large ungulate species had declined. Five competing factors that could be responsible for these changes were investigated. (i) Rainfall increased slightly over 25 years and (ii) no obvious outbreaks of disease were witnessed, suggesting that populations are not suffering food shortages or disease. (iii) Large predators live at low densities and are not increasing, and estimates suggest that that predation is unlikely to impact larger prey species. (iv) Some assessments of illegal hunting indicate little influence on herbivore populations but one measure points to giraffe, hippopotamus, warthog and perhaps other species being adversely affected. (v) Tourist hunting quotas of lions and greater kudu in hunting blocks appear high and there are indications that both may be declining. Preliminary data, approximate calculations and elimination of hypotheses point to anthropogenic factors being partly responsible for changes in this ecosystem and constructive recommendations are made to alter these. More generally, this study highlights the importance of monitoring in conjunction with collecting diverse data when trying to stop population declines before they become too serious.
Identidades Islámicas Contemporáneas en América Latina
Isaac Caro
Universum : Revista de Humanidades y Ciencias Sociales , 2007,
Abstract: En este artículo, distinguimos cuatro grandes modelos del "Islam latinoamericano". Primero, la conformación de comunidades musulmanas a partir de un "islam indo-asiático". Segundo, el predominio, especialmente en los países sudamericanos, de un "islam árabe". Tercero, un proceso creciente de conversión al islam a través de la formación de "nuevos musulmanes". Cuarto, un fenómeno de carácter minoritario, que tiene que ver con la presencia de una tendencia islamista. Postulamos que la diversidad que caracteriza al Islam, por una parte, y a las distintas corrientes del islamismo, por otra, también alcanza a América Latina, a través de estos diversos modelos y, en algunos casos, antagónicos In this paper, we examine four "Latin American Islam" models. First, the configuration of Muslim communities in the Caribbean: the "Indo-Asiatic Islam". Second, the formation, in South American countries, ofan "Arabic Islam". Third, the "new Muslims", through a conversion process to Islam. Finally, the presence of a radical Islamism. We postulate that the diversity that characterizes Islam and Islamism is related also with Latin America, through the conformation of some models that are diverse and antagonist in some cases
