Evaluación preliminar de la colección de frijol común (Phaseolus vulgaris L) del Banco de Germoplasma del Regen; en época de postrera en la Estación Experimental La Compañía, Carazo

El presente trabajo se realizó en la época de postrera (Octubre-Diciembre) de 1995, en la Estación Experimental La Compañía en el departamento de Carazo, con los objetivos de evaluar preliminarmente la colección de germoplasma de frijol común (Phaseolus vulgaris L.), encontrar material promisorio a ser utilizados en programas de mejoramientos y mostrar tendencias en la respuestas del material evaluado a la fertilización. Las accesiones objeto de estudios fueron colectadas en diferentes regiones geográficas del país y almacenadas en el banco de germoplasma del Programa de Recursos Genéticos Nicaraguenses (REGEN). Se utilizaron dos testigos, la variedad mejorada DOR-364 y Compañía 93, el diseño consistió en un ensayo preliminar con dos repeticiones una fertilizada y la otra sin fertilizar, los análisis estadísticos realizados a los datos fueron: Media, Desviación Standar, distribución de frecuencias y correlaciones fenotípicas Pearson entre los caracteres evaluados, se midieron trece variables ocho sobre fenología cuatro sobre rendimientos y sus componentes y enfermedades dentro de las cuales se evaluaron mancha angular, roya y bacteríosis. Se observaron amplíos rangos de comportamiento sobre fenología. rendimiento y sus componentes y enfermedades. 195 accesiones fueron más precoces que e1 testigo Compañía 9J y 244 más que el DOR-364 bajo sistema no fertilizado. En el sistema fertilizado 184 accesiones mostraron mayor precocidad que Compañía 93 y 220 más que DOR-364. Como accesiones altamente productivas se pueden señalar: 1740, 3145, 1793 y la 2145, ya que superaron a ambos testigos en los dos sistemas evaluados. Se observó que existen accesiones con tendencias a responder al fertilizante, de los componentes del rendimiento, vainas por planta presentó las mayores diferencias entre sistemas. En cuanto a enfermedades, mancha angular presenta los mayores niveles de severidad 2 y 3.

Ground-water resources data of Charlotte, DeSoto, and Hardee Counties, Florida

Charlotte, De Soto, and Hardee counties are east-southeast of Tampa in west-central peninsular Florida, figure 1. In order to plan the future water-resource development of the area, information about the water resources is needed. To meet this need, the Water Resources Division of the U.S. Geological Survey, in cooperation with the Peace River Basin Board of the Southwest Florida Water Management District as part of the statewide cooperative program with the Division of Geology, Florida Board of Conservation, began a continuing hydrologic data collection program in July, 1963, as an initial step in the investigation and evaluation of the groundwater resources of Hardee and De Soto counties. A similar hydrologic data program commenced in Charlotte County in July, 1964. Previous work in Hardee and De Soto counties included a one year reconnaissance by the Division of Water Resources and Conservation, Florida Board of Conservation, which concluded in June, 1963, and resulted in a hydrologic report (Woodard, 1964). As an outgrowth of the hydrologic data program, a Map Series report portraying the chemical character of water in the Floridan aquifer in the southern Peace River basin was prepared in 1967 (Kaufman and Dion). The data contained herein constitute the basis for the Map Series report. Additional selected data, including records of wells and chemical analyses,, on the ground-water resources of the three county area are also included and are published to make the data available.

Multiwavelength observations of the black hole candidate 1E 1740.7-2942

Observations of the Galactic center region black hole candidate 1E 1740.7-2942 have been carried out using the Caltech Gamma-Ray Imaging Payload (GRIP), the Röntgensatellit (ROSAT) and the Very Large Array (VLA). These multiwavelength observations have helped to establish the association between a bright emitter of hard X-rays and soft γ-rays, the compact core of a double radio jet source, and the X-ray source, 1E 1740.7-2942. They have also provided information on the X-ray and hard X-ray spectrum.

The Galactic center region was observed by GRIP during balloon flights from Alice Springs, NT, Australia on 1988 April 12 and 1989 April 3. These observations revealed that 1E 1740.7-2942 was the strongest source of hard X-rays within ~10° of the Galactic center. The source spectrum from each flight is well fit by a single power law in the energy range 35-200 keV. The best-fit photon indices and 100 keV normalizations are: γ = (2.05 ± 0.15) and K_(100) = (8.5 ± 0.5) x 10^(-5) cm^(-2) s^(-1) keV^(-1) and γ = (2.2 ± 0.3) and K_(100) = (7.0 ± 0.7) x 10^(-5) cm^(-2) s^(-1) keV^(-1) for the 1988 and 1989 observations respectively. No flux above 200 keV was detected during either observation. These values are consistent with a constant spectrum and indicate that 1E 1740.7-2942 was in its normal hard X-ray emission state. A search on one hour time scales showed no evidence for variability.

The ROSAT HRI observed 1E 1740.7-2942 during the period 1991 March 20-24. An improved source location has been derived from this observation. The best fit coordinates (J2000) are: Right Ascension = 17^h43^m54^s.9, Declination = -29°44'45".3, with a 90% confidence error circle of radius 8".5. The PSPC observation was split between periods from 1992 September 28- October 4 and 1993 March 23-28. A thermal bremsstrahlung model fit to the data yields a column density of N_H = 1.12^(+1.51)_(0.18) x cm^(-2) , consistent with earlier X- ray measurements.

We observed the region of the Einstein IPC error circle for 1E 1740.7-2942 with the VLA at 1.5 and 4.9 GHz on 1989 March 2. The 4.9 GHz observation revealed two sources. Source 'A', which is the core of a double aligned radio jet source (Mirabel et al. 1992), lies within our ROSAT error circle, further strengthening its identification with 1E 1740.7-2942.

Bycatch and catch-release mortality of small sharks in the Gulf coast nursery grounds of Tampa Bay and Charlotte Harbor

The bays and estuaries of the southeast United States coast generally are thought to serve as nursery areas for various species of coastal sharks, where juvenile sharks find abundant food and are less exposed to predation by larger sharks. Because these areas typically support substantial commercial and recreational fisheries, fishing mortality of sharks in the nurseries particularly by bycatch, may be significant. This two-year project assessed the relative importance of two estuaries of the southwest Florida Gulf coast, Tampa Bay and Charlotte Harbor/Pine Island Sound, as shark nursery areas, and examined potential fishing mortality of these young sharks in the nurseries.
