Assessment of stability of expression of various male-sterile genes in muskmelon in sub-tropical field conditions National Institute of Agronomic Research
Dhillon, N.P.S.; Kumar, J..
Five melon (Cucumis melo L.) progenies segregating for five male-sterile genes (ms-1, ms-2, ms-3, ms-4, and ms-5) along with two male-fertile cultivars were evaluated for phenotypic variation in expression of fertility in sub-tropical field conditions, for two years. Male-fertile plants of three progenies of ms-1, ms-2, and ms-3 were phenotypically unstable and produced more male-sterile flowers than plants of normal male-fertile cultivars. Progenies of ms-4 and ms-5 were stable for the expression of male-fertile plants.

Cambios en los compuestos volátiles de un concentrado de sabor limón por la presencia de ácido cítrico OceanDocs
Pino, J. A.; Sauri-Duch, E.; Cuevas-Glory, L..
En el presente trabajo se estudiaron los cambios de los componentes volátiles de un concentrado de sabor limón para preparar bebidas de limón durante 6 meses de conservación a 40 ºC. Se identificaron 44 compuestos aislados mediante microextracción en fase sólida del espacio de cabeza en combinación con la cromatografía de gases- espectrometría de masas. El limoneno, γ-terpineno, acetato de citronelilo, acetato de nerilo y acetato de geranilo, disminuyeron su contenido significativamente, mientras que el 1,4-cineol, 1,8-cineol, p-cimeno, p-cimeneno, p-menta-1,3- dien-8-ol, α-terpineol, trans-α-bergamoteno, ar-curcumeno, (E,E)-α-farneseno y β-bisaboleno la incrementaron. El neral y geranial parecen disminuir su contenido, pero estos cambios no explican todo...

Coalitional Matchings AgEcon
Dimitrov, Dinko; Lazarova, Emiliya A..
A coalitional matching is a two-sided matching problem in which agents on each side of the market may form coalitions such as student groups and research teams who - when matched - form universities. We assume that each researcher has preferences over the research teams he would like to work in and over the student groups he would like to teach to. Correspondingly, each student has preferences over the groups of students he wants to study with and over the teams of researchers he would like to learn from. In this setup, we examine how the existence of core stable partitions on the distinct market sides, the restriction of agents’ preferences over groups to strict orderings, and the extent to which individual preferences respect common rankings shape the...

Colour and stability of pure anthocyanins in aqueous solutions at high pH values IPB - Escola Superior Agrária
Andersen, Øyvind M.; Fossen, Torgils; Cabrita, Luís.
This study on anthocyanin colour variation (intensity, lambda max, molar absorbptivity) over the pH range 1-9 during 60 days of storage, was conducted on petunidin 3-[6-O-(4-O-E-p-coumaroyl-O-alfa-L-rhamnopyranosyl)-beta-D-glucopyranoside]-5-O-beta-D-glucopyranoside (petanin) and cyanidin 3-O-beta-D-glucopyranoside (cy3glc) at 10 and 23ºC. Compared to cy3glc, petanin afforded higher colour intensity and higher or similar stability throughout the whole pH range. At pH 4.0, 84% of petanin was intact after 60 days storage at 10ºC, while the corresponding solution of cy3glc was totally degraded. At pH 8.1 the colour intensity of petanin was even higher than at the lowest pH values. The visible lmax absorption of petanin after 5 days at pH 8.1 at 10ºC was...

Colour and stability of the six common anthocyanidin 3-glucosides IPB - Escola Superior Agrária
Cabrita, Luís; Fossen, Torgils; Andersen, Øyvind M..
This study on anthocyanin stability and colour variation (lambda max, absorptivity) in the pH range 1-12 during a period of 60 days storage at 10 and 23ºC, was conducted on the 3-glucosides of the six common anthocyanidins. It was mostly in the alkaline region that differences in colour and stability became significant. Although it has been generally accepted that anthocyanins are stable only at low pH values, this study revealed that, for some of the anthocyanin 3-glucosides (e.g. malvidin 3-glucoside), the bluish colours were rather intense and stability relatively high in the alkaline region. Thus, they can be regarded as potential colorants for some slightly alkaline food products.

Connections Among Farsighted Agents AgEcon
Grandjean, Gilles; Mauleon, Ana; Vannetelbosch, Vincent.
We study the stability of social and economic networks when players are farsighted. In particular, we examine whether the networks formed by farsighted players are different from those formed by myopic players. We adopt Herings, Mauleon and Vannetelbosch’s (Games and Economic Behavior, forthcoming) notion of pairwise farsightedly stable set. We first investigate in some classical models of social and economic networks whether the pairwise farsightedly stable sets of networks coincide with the set of pairwise (myopically) stable networks and the set of strongly efficient networks. We then provide some primitive conditions on value functions and allocation rules so that the set of strongly efficient networks is the unique pairwise farsightedly stable set....

Constrained School Choice: An Experimental Study AgEcon
Calsamiglia, Caterina; Haeringer, Guillaume; Klijn, Flip.
The literature on school choice assumes that families can submit a preference list over all the schools they want to be assigned to. However, in many real-life instances families are only allowed to submit a list containing a limited number of schools. Subjects' incentives are drastically affected, as more individuals manipulate their preferentes. Including a safety school in the constrained list explains most manipulations. Competitiveness across schools plays an important role. Constraining choices increases segregation and affects the stability and efficiency of the final allocation. Remarkably, the constraint reduces significantly the proportion of subjects playing a dominated strategy.

Diversity and stability of an estuarine trophic network ArchiMer
Lobry, Jeremy; David, V; Pasquaud, S; Lepage, M; Sautour, B; Rochard, E.
Estuarine areas provide highly valuable ecosystem benefits for human populations, despite being under intense demographic, economic and ecological pressures. Hence, an understanding of the structure and function of estuarine ecosystems is essential for understanding the persistence and stability of these ecosystems and their response to perturbations. This study synthesises available data and knowledge about the Gironde estuary (SW France) in a mass-balanced trophic model to illustrate potential key patterns in the functioning of the estuarine ecosystem and key elements of its stability. In order to evaluate the total direct and indirect impact on the whole community of the 2 main sources of anthropogenic perturbations in the estuarine area, mortalities...

Diversity and stability of fishes (Teleostei) in a temporary river of the Brazilian semiarid region Iheringia, Sér. Zool.
Medeiros,Elvio S.F.; Maltchik,Leonardo.
The effects of hydrological disturbances by flooding and drought on the diversity and stability in a temporary river fish community in the Brazilian semiarid region were analyzed over the 1996 hydrological cycle. Twelve collections of fishes were made during the wet and dry phases, and 789 individuals of 16 species were collected. Diversity was measured using Simpson's Index (S) and community stability was analyzed by the variation in abundance using Kendall's W concordance test. Fish diversity in the Taperoá river was subjected to hydrological disturbances by flooding and drought. During the wet phase the diversity was higher (S = 0.855) than during the dry phase (S = 0.771). The community was considered stable during the whole annual hydrological cycle...

Effect of Californian Red Worm (Eisenia foetida) on the Nutrient Dynamics of a Mixture of Semicomposted Materials Chilean J. Agric. Res.
Castillo,Hugo; Hernández,Adriana; Dominguez,David; Ojeda,Damaris.
The efficiency of composting processes with and without the addition of Californian red worms (Eisenia foetida) was evaluated, using manure of dairy cows to generate organic fertilizer. Several parameters were assessed as physio-chemical indicators of maturity, such as temperature, pH, C/N ratio, phytotoxicity and macro and micronutrients at 25 and 54 ws (mature and stored products, respectively). A linear model was used in the statistical analysis, with four replicates that included as fixed effects, the composting systems and time. At 25 wk, both systems reduced the C/N ratio to values of 15.5 in vermicompost and 17.1 in semi-compost. The content of total N, N-NO3, Ca and some micronutrients also increased. K and Na concentrations were higher in the...

Estimación de parámetros genéticos en cruzas intervarietales de maíz para la región semicálida de Guerrero. Colegio de Postgraduados
Palemón Alberto, Francisco.
La orografía y agroecología del estado de Guerrero es muy diversa. En las áreas de altitud intermedia (1200 a 1700 m) prácticamente no se siembran con variedades mejoradas de maíz, debido a su limitada adaptación a las condiciones climáticas y edáficas; por lo que, prevalece la siembra de poblaciones nativas. En las áreas semicálidas se ha seleccionado germoplasma subtropical local; paralelamente, en Valles Altos se aplicó selección para adaptación en cuatro poblaciones tropicales durante 10 años. Con estas siete poblaciones progenitoras se generaron 12 cruzas intervarietales (CI) en arreglo factorial, con el propósito de valorar los avances del mejoramiento genético y detectar alguna CI de valor comercial. Las CI, sus progenitores y testigos se evaluaron...

EVALUATION OFRhizophora mangle BARK COMING FROM THE WESTERN AREA OF CUBA FOR BIOMEDICAL DESTINATION Rev Salud Anim.
Escobar,A; Fragas,Ivis; Sánchez,Luz M; Pérez,Tania; Riverón,Yamilka; Marrero,Evangelina.
Cuban mangroves constitute the 5% of the country surface and they are distributed in the whole coast of the island. One of the species represented is Rhizophora mangle L. (red mangrove). From the bark of this plant, new drugs for human and veterinary use have been obtained. All the areas studied in the western region showed values of soluble substances (>14.5 mg/ml); ash (< 12%); total tannins (>6 mg/ml) and percentage of polymerized polyphenolic compounds (PPC) (>90%). Rhizophora mangle bark can be collected in every season. It is stable for more than one year when being stored in polyethylene sacks in a fresh place at room temperature (25 ± 5°C) with a relative humidity between 70-90%.
