1. Evidence of accelerated and altered pollen development after Imazapyr treatment in resistant sunflower
ABSTRACT Imazapyr (IM) treatment applied at early reproductive developmental stages have been associated with induced male sterility in sunflower (Helianthus annuus L.). The aim of this work was to determine the effects induced by two different doses of IM-treatment (1X and 2X; 80 and 160 g a.i.·ha-1) on pollen grain yield, pollen viability and on the exine

2. Changes in leaf appearance and developmental phases associated with breeding progress in six-rowed barley in the Pannonian Plain
Abstract The aim of this study was to analyze traits of leaf appearance and phenological development related to grain yield gain in winter barley cultivars released over the past 50 years. Field trials with 15 six-rowed winter barley cultivars were conducted during two growing seasons. The main leaf appearance and developmental traits were studied. The durat

4. Tadpoles of the High-Andean Hyloxalus subpunctatus (Anura: Dendrobatidae) with description of larval variation and species distinction by larval morphology
This study redescribes the tadpoles of Hyloxalus subpunctatus (Anura: Dendrobatidae) based on larvae from the type locality and over most of its geographic range, including all stages of ontogenetic development. I describe tadpoles in the three developmental phases: (1) back-riding tadpoles, (2) free-swimming tadpoles, (3) froglets or individuals in metamorp

5. Avaliação da expressão de receptores e ligantes Notch nas populações de linfócitos T em desenvolvimento, linfócitos T reguladores naturais e células dendríticas no timo humano / Evaluation of the expression of Notch receptors and ligands in developing lymphocytes, natural regulatory T cells and dendritic cells in human thymus
The thymus is a primary lymphoid organ responsible of maturing T lymphocytes, where specialized structures and cells are observed. The intrathymic signaling during lymphocytes maturation is unclear. Among them, Notch signaling pathway, which comprises in receptors (Notch1-4) and ligands (DLL1, 2 and 3, Jaaged1 and 2), may regulate this process. In this work

6. Efeitos de um programa de habilidades sociais comunicativas para crianças com distúrbio específico de linguagem / Effects of a Social Communicative Skills Program for Children with Specific Language Impairment
The language is considered the first form of socialization of the child, and, in most cases, is done explicitly by parents through verbal instructions during daily activities. Thus, the child has access, even before learning to speak, the values, beliefs and rules, by contacting the concepts of their culture. However, some children experience serious difficu

7. Five models of capitalism
Besides analyzing capitalist societies historically and thinking of them in terms of phases or stages, we may compare different models or varieties of capitalism. In this paper I survey the literature on this subject, and distinguish the classification that has a production or business approach from those that use a mainly political criterion. I identify fiv

9. Meeting embryonic requirements of broilers throughout incubation: a review
During incubation of chicken embryos, environmental conditions, such as temperature, relative humidity, and CO2 concentration, must be controlled to meet embryonic requirements that change during the different phases of embryonic development. In the current review, the effects of embryo temperature, egg weight loss, and CO2 concentration on hatchability, hat

10. Morphologic analysis of developmental phases and gill ontogenesis in neotropical species Poecilia vivipara (Cyprinodontiformes: Poeciliidae) exposed to different salinities
The present study evaluated and characterized the different phases of development and the cell types present in the gill epithelium of embryos, larvae, and fingerlings of guppy (Poecilia vivipara Bloch & Schneider, 1801) specimens exposed to water with salinity ranging from 0‰ to 20‰. The development of P. vivipara was classified into eight phases. The y

11. Biology and morphology of Molippa cruenta (Lepidoptera: Saturniidae) in the laboratory
The goal of this contribution was to study the biology and morphology of all developmental stages of Molippa cruenta (Walker, 1855), a member of Hemileucinae (Saturniidae), endemic to southern Brazil and northeastern Argentina. Daily observations were carried out on individuals reared under controlled temperature (25 ± 1ºC), relative humidity (70 ± 10%) a

12. Calibração e avaliação do modelo ORYZA-APSIM para o arroz de terras altas no Brasil / Calibration and evaluation of the ORYZA-APSIM model for the upland rice in Brazil
With the purpose of calibrating and evaluating the ORYZA-APSIM model for the upland rice in Brazil, seventeen field experiments were carried out at EMBRAPA Arroz e Feijão, in four upland rice Brazilian regions (Santo Antônio de Goiás-GO, Sorriso-MT, Gurupi and Teresina-PI), from 2005/2006 to 2008/2009 seasons. The model was calibrated and evaluated for an
