| Las acciones y programas encaminados a la tecnificación y modernización de los distritos de riego del país han sido diseñados para mejorar la infraestructura de estos y hacer un uso eficiente del agua. Un parámetro que permite la evaluación de estas mejoras es la productividad que presentan los cultivos, relacionando su rendimiento y el aprovechamiento del agua. Con el propósito de determinar el impacto que han tenido las acciones encaminadas a mejorar la infraestructura en el distrito de riego 053 “Estado de Colima”, se recopiló, proceso y organizó la información de superficie cosechada para los cultivos perennes, que han recibido la mayor inversión para la tecnificación y modernización de las redes de conducción y distribución del agua. El estudio se... |

| Radar altimeters have been measuring ocean significant wave height for more than three decades, with their data used to record the severity of storms, the mixing of surface waters and the potential threats to offshore structures and low-lying land, and to improve operational wave forecasting. Understanding climate change and long-term planning for enhanced storm and flooding hazards are imposing more stringent requirements on the robustness, precision, and accuracy of the estimates than have hitherto been needed. Taking advantage of novel retracking algorithms, particularly developed for the coastal zone, the present work aims at establishing an objective baseline processing chain for wave height retrieval that can be adapted to all satellite missions. In... |

| The aim of this research was to use a system of 37 variables of morphological characteristics on a sample of 108 elite male athletes (25 karatekas, 27 judokas, 19 taekwondoists, 18 boxers and 19 wrestlers), aged 17 to 23, to determine any statistically significant differences between the groups of athletes in terms of variable means, so that during the training process, the selection of athletes could be carried out in a proper and objective manner and that the training transformation processes could be managed more effectively. After processing the data using the statistical method of a multivariate and univariate analysis of variance (MANOVA/ANOVA), we obtained results that indicate that among the karatekas, judokas, taekwondoists, boxers and wrestlers... |

| The present paper constitutes an introduction to taxonomic methodology. After an analysis of taxonomic practice, and a brief survey of kinds of attributes, the paper deals with observation, description, comparison, arrangement and classification, hypothesis construction, deduction, model, experiment, abstraction, and synthesis. The methodological aspects of the species-concept and of biological classification are dealt with in two final sections. |

| The wood structure of 78 species from 27 genera representing the woody primuloids (Maesaceae, Myrsinaceae, and Theophrastaceae) was investigated using light microscopy (LM) and scanning electron microscopy (SEM). Results indicated that the ray structure, the nature of mineral inclusions, and the occurrence of breakdown areas in rays can be used to separate the three primuloid families from each other. Within Ericales, the presence of exclusively multiseriate rays is synapomorphic for Myrsinaceae and Theophrastaceae, and the occurrence of breakdown areas in rays is synapomorphic for Myrsinaceae. Within Myrsinaceae, the wood structure of the mangrove genus Aegiceras differs because it has short vessel elements that are storied, non-septate fibers, a... |

| ABSTRACT: Iris is the largest genus of family Iridaceae having 50 species with 24 endemic to Turkey. Here in this study we compared morphological, anatomical and ecological characters of two varieties of Iris unguicularis subsp. carica (Iris unguicularis subsp. carica var. carica and Iris unguicularis subsp. carica var. syriaca) from Turkey. We reported some distinctive morphological characteristics between both of the varieties like plant size, root length and width, leaf length and width, perianth tube, falls, standard fruit and bract length, falls and standards width and structure, flower colour which are of important taxonomic values. We further investigated that both the varieties are found in different localities and the differences in morphological... |

| Using Monte-Carlo simulation, , we compare the most popular demand systems including the LES, AIDS, BTL, QES, QUAIDS and AIDADS, and find that different models actually have different advantages in estimating different elasticities. Specifically, QES, AIDS and AIDADS models are the best in income, own-price and cross-price elasticities, respectively. Overall, AIDADS model has the best performance. The results indicate that the rank three models are not necessary always better than the rank two models. |

| The Hungarian sheep sector has become a one-market sector, almost the whole amount of slaughter lamb went to Italy. It would worth to exploit possibilities in other European markets. Such markets can be the Spanish and Greek for ”light” and the French, German and English markets for ”heavy” lambs. The European lamb prices are characterized by large seasonal fluctuation and the degree and timing of changes are different. Due to these seasonal changes, the producers often suffer great losses. Study of the literature on lamb sales called for an analysis of price forecasting. In my study, I performed a forecasting of lamb prices in Hungary, Italy and Greek for the period between 1996 and 2007 based on the data of the European Committee. Among the forecasting... |
