Variabilidade espacial da densidade do solo sob manejo da irrigação

Este trabalho foi desenvolvido em um solo aluvial na Estação Experimental da Empresa Brasileira de Pesquisa Agropecuária (EMBRAPA) Algodão, município de Souza, Estado da Paraíba, Brasil, com o objetivo de estudar a variabilidade espacial da densidade do solo. A área tem uma superfície cultivada de 17 ha e os testes de campo foram feitos em 40 pontos amostrais, locados na linha central longitudinal de cada parcela agrícola, eqüidistante de 50 m. Na determinação da densidade do solo, foi utilizado o método do anel volumétrico, em amostras com estrutura indeformada para as profundidades de 0-30, 30-60 e 60-90 cm. A variabilidade espacial foi determinada pela técnica de estatística clássica e da geoestatística. Na análise estatística clássica, a densidade do solo para as três profundidades apresentou baixos valores de desvio-padrão e coeficiente de variação, indicando pouca variação da densidade do solo com aumento da profundidade. A densidade do solo manifestou estrutura de dependência espacial, modelada por meio de semivariogramas, os quais permitiram a interpolação por Krigagem, apresentando estrutura esférica nas profundidades de 0-30 e 60-90 cm, com alcance de 46 m e estrutura exponencial com alcance de 255,10 m para a profundidade 30-60 cm.

RH maps of bovine chromosomes 15 and 29: conservation of human chromosomes 11 and 5

Comparative mapping data on evolutionary conserved coding sequences and synteny maps between human and cattle are insufficient to define the extent and distribution of conserved segments between these two species, because the order of loci is often rearranged. A 5000-rad cattle whole-genome radiation hybrid (WG-RH) panel was constructed to provide high-resolution comparative maps and also to integrate linkage maps of microsatellites with evolutionary conserved genes and transcripts in a single ordered map. We used the WG-RH panel to construct radiation hybrid maps of bovine Chromosomes (Chrs) 15 and 29 (BTA15 and BTA29), integrating microsatellites from published linkage maps with selected genes. The comprehensive map of BTA15 consists of 24 markers. 13 of which were placed in the framework map. Eleven molecular markers compose the comprehensive map of BTA29. seven of which were placed in the framework map. We identified the homologous regions between bovine Chr 15 (BTA15) and human Chrs 5 and 11 (HSA5 and HSA11), as well as between BTA29 and HSA11, the present study demonstrates that WG-RH mapping is an efficient method for integrating multiple genetic maps into one map and for incorporating monomorphic Type I loci into ordered maps for comparison between species.

Seletividade e eficácia de herbicidas inibidores da enzima accase na cultura da mamona

This experiment aimed to evaluate the selectivity and efficacy of ACCase-inhibiting herbicides in castor bean crop, at Paraguacu Paulista, São Paulo, during the 2002/03 agricultural season. The experimental design used was randomized complete blocks, with eleven treatments and four replicates, constituted by the following herbicides and adjuvants: fluazifop-p-butyl 313 g ha(-1)) + Agral (TM) 0.2% v/v); sethoxydim 322 g ha(-1)) + Assist (TM) 0.5% v/v); haloxyfop-methyl 120 g ha(-1)) + Assist (TM) 0.5% v/v); clethodim+ fenoxaprop-p-ethyl 75 g ha(-1)) + Assist (TM) 0.5% v/v); quizalofop-pethyl 125 g ha(-1)) + Assist (TM) 0.5% v/v); clethodim 156 g ha(-1)) + Assist (TM) 0.5% v/v); propaquizafop 175 g ha(-1)) + Assist (TM) 0.5% v/v); tepraloxydim 400 g ha(-1)) + Dash (TM) 0.5% v/v); butroxydim 100 g ha(-1)) + Dash (TM) 0.5% v/v); isoxaflutole 60 g ha(-1)) and weed-free check. At the moment of application, castor bean plants presented 4 to 6 leaves and Cenchrus echinatus, 1 to 5 tillers. AL Guarany 2002 cultivar presented high selectivity to ACCase-inhibiting herbicides, without visible symptoms of phytotoxicity in 14 DAA days after application), except for tepraloxydim, whose symptoms persisted until 21 DAA, and isoxaflutole HPPD inhibiting), which showed injuries in older leaves and significant yield reduction. C. echinatus infestation was efficiently controlled by ACCase-inhibiting herbicides between 14 and 21 DAA (>= 95.0%).

Trisomy X and 1 29 translocation in infertile heifers

In a group of 12 Pitangueiras breed heifers exhibiting a high return rate to service, three were noted to be carriers of the 1 29 translocation. One of the heifers exhibited trisomy for the X-chromosome in addition to the 1 29 translocation. The appearance and external genitalia of the 1 29 T; trisomy X heifer were not altered, although on rectal examination the internal genitalia, including the ovaries, appeared similar to that of a prepubertal heifer. © 1987.

Staphylococcus epidermidis biofilms control by N-acetylcysteine and rifampicin

Medical device-associated infections caused by Staphylococcus epidermidis usually involve biofilm formation and its eradication is particularly challenging. Although rifampicin has been proving to be one of the most effective antibiotics against S. epidermidis biofilms, its use as a single agent can lead to the acquisition of resistance. Therefore, we assessed the combined effect of rifampicin with N-acetylcysteine (NAC) known by its mucolytic effect, in the control of S. epidermidis biofilms. Biofilms of 2 S. epidermidis strains (9142 and 1457) were treated with 1× minimum inhibitory concentration (4 mg/mL) and 10× minimum inhibitory concentration (40 mg/mL) of NAC and 10 mg/L (peak serum) of rifampicin alone and in combination. NAC at 40 mg/L alone or in combination with rifampicin (10 mg/L) significantly reduced (4 log 10) the number of biofilm cells. Considering their different modes of action, the association of NAC with rifampicin constitutes a promising therapeutic strategy in the treatment of infections associated to S. epidermidis biofilms. © 2013 Lippincott Williams & Wilkins.
