Aceptación de tres líneas de fríjol (Phaseolus vulgaris L.) mejorado nutricionalmente por los consumidores nicaragüenses
Carrillo Centeno,Patricia; Chow,Zildghean; Cuadra,Sergio; Brenes,Douglas; Pachón,Helena;
Perspectivas en Nutrición Humana , 2011,
Abstract: objective: using sensory evaluation methods, assess acceptability and preference with respect to three nutritionally improved bean lines (phaseolus vulgaris l.): (a) 187 sdcf 15488, (b) 194 sdcf 15488 and (c) mib 395, as well as a local check, (d) inta rojo. materials and methods: seventy six farmers, who grow and consume beans, from two departments in northern nicaragua, participated. two sensory evaluation methods were applied: acceptability (overall and by attribute) and preference. results: there were no statistically significant differences in the scores assigned to overall acceptability or the smell, color, taste and texture attributes (p>0,05). for preference, there was no difference in the percentage of persons who preferred each of the four beans. conclusions: among four beans, there was no difference in farmers′ acceptability or preference, suggesting that nutritionally improved beans can be delivered to rural nicaraguans; farmers in these regions should be informed of the agronomic characteristics of these beans.
Extensions of rational modules

Abstract: For a coalgebra C, the rational functor Rat (−):ℳC∗→ℳC∗ is a left exact preradical whose associated linear topology is the family ℱC, consisting of all closed and cofinite right ideals of C∗. It was proved by Radford (1973) that if C is right ℱ-Noetherian (which means that every I∈ℱC is finitely generated), then Rat (−) is a radical. We show that the converse follows if C1, the second term of the coradical filtration, is right ℱ-Noetherian. This is a consequence of our main result on ℱ-Noetherian coalgebras which states that the following assertions are equivalent: (i) C is right ℱ-Noetherian; (ii) Cn is right ℱ-Noetherian for all n∈ℕ; and (iii) ℱC is closed under products and C1 is right ℱ-Noetherian. New examples of right ℱ-Noetherian coalgebras are provided.

A Hopf algebra having a separable Galois extension is finite dimensional
Juan Cuadra
Mathematics , 2006,
Abstract: It is shown that a Hopf algebra over a field admitting a Galois extension separable over its subalgebra of coinvariants is of finite dimension. This answers in the affirmative a question posed by Beattie et al. in [{\it Proc. Amer. Math. Soc.} 128 No. 11 (2000), 3201-3203].
5th Milan Breast Cancer Conference, Milan, Italy, 11–13 June 2003

Abstract: The conference was guided to a successful conclusion by the experience of the chairmen Dr Umberto Veronessi and Dr Aaron Goldhirsch. This year the European Institute of Oncology Award was given to Dr David Page, Professor at Vanderbilt University Medical School, who gave an excellent lecture outlining the importance of ductal carcinoma in situ as a local precursor of invasive cancer, and the lesions related to in situ staging.Management of high risk women is a major topic. Therefore, the first section of the conference was dedicated to prevention and detection. The main points were summarized in a plenary session. Jack Cuzick (Imperial Cancer Research, UK) gave an overview of the risk factors, which can be divided into four groups: family history/genetic; reproductive/hormonal; proliferative benign breast disease; and mammographic density. Less is known about the possible interactions between these factors. However, a computer program able to synthesize the factors into an individual risk profile could conduct an assessment.Following this broad definition of high risk, Judy Garber (Dana Faber Cancer Institute, Boston, MA, USA) showed that BRCA mutations are the cause of breast cancer in only 5–10% of the total cases. In addition, BRCA mutation carriers have a 40–60% risk for developing contralateral breast cancer. Julian Peto (Institute of Cancer Research, Sutton, UK) emphasized the importance of reproductive factors in breast cancer.In chemoprevention Andrea Decensi (European Institute of Oncology) and Lawrence Wickerham (Associate Chairman of the National Surgical Adjuvant Breast and Bowel Project) showed that the use of tamoxifen can reduce the incidence of oestrogen receptor (ER) positive breast cancer by up to 50%; however, the effect of tamoxifen in ER negative breast cancer is unknown. The dosage of tamoxifen, and the concomitant use of hormone replacement therapy and tamoxifen 5 mg/day will be evaluated in the Hormone Replacement Therapy and Tamoxifen (HOT)
Where Does Mexico Stand? Interpreting NAFTA's. Regional Scope and the FTAA Hemispheric Project
Cuadra Montiel, Héctor;
Norteamérica , 2008,
Abstract: using a hermeneutic strategic relational approach, this article examines the elements of the material and ideational international context directly relevant to development in mexico. it opens with a section on relations between the united states and mexico. the myriad of complex and multifaceted interactions, history and potentialities has been -and will remain- of utmost importance for both countries. the next part focuses on the north american free trade agreement (nafta) which, evaluated under its own terms, has unquestionably been successful. trade and investment have increased, and the ad hoc dispute settlement mechanism operated regularly in cases presented by each member. yet, there are immense numbers of things that nafta cannot accommodate, as it has been narrowly conceived only as a trade agreement, albeit an expanded one. these omissions are of key relevance and must be spotlighted along with the agreement's relative successes for a serious, informed discussion to take place about the prospects of deepening nafta. likewise, the negotiations for the free trade area of the americas (ftaa) would mean broadening its scope and membership. these are some of the key issues in the strategically selective context for the social processes of change in mexico in the last few decades. crucial challenges also lie ahead. if room for manoeuvre has existed in the past, there is a good chance that it will be greater in the future.
Conflito social e movimento estudantil no Chile
de la Cuadra, Fernando;
Estudos Históricos (Rio de Janeiro) , 2008, DOI: 10.1590/S0103-21862008000200004
Abstract: the following article is a statement about the way chilean government reacted to the conflict raised by high school students practically along the whole first year of bachelet's administration. aside from trying to outline the causes which would be behind the erratic answer given by the authorities, the study intends to understand the position held by some of the sectors in government along with the political society in regard to the uprising of the social conflict. we think it is pertinent to build a new concept taking into account the chilean and latin-american experience. this concept is referred to what we call "hypergovernability", in other words, an excessive attachment to maintain governability by means of "anticipated solutions" of social demands. the current analysis of the various student movements indicates a fear, almost panic, in regard to social conflict, and a disproportionate concern of the state with peace and social cohesion.
Efecto de la variación entre ensayos de los estímulos de segundo orden sobre la adquisición y transferencia en una tarea de discriminación condicional
Bueno Cuadra, Roberto;
Revista mexicana de análisis de la conducta , 2008,
Abstract: the effect of three conditions of variation of the second-order stimuli (sosi) across trials in a conditional discrimination task was investigated in human adult participants. the conditions were: (a) no variation; (b) partial variation (only in shape and color); and (c) total variation (in shape, color, size and filling weft). identity and difference relations were examined. each group received only a single combination of type of relation and type of sosi variation. for all groups there were four phases: baseline (a); training with a new set of sample and comparison stimuli and feedback (b); intramodal transfer test with the same sample and comparison stimuli of the phase a (c); and extramodal transfer test (d). the partial and total variation conditions generated the highest percentages of correct responses in phases b and c, but only in some participants from the identity groups in these two conditions evidence of extramodal transfer was clearly attained. these results suggest that a greater variety of the sosi facilitates the discrimination of the relation between these stimuli and, this way, the development of abstract performances in this kind of tasks.
