Cultivar selection, planting geometry, and plant population are the key factors determining grain sorghum yields in water deficit areas. The objective of this study was to investigate whether clump geometry (three plants clustered) improves microclimate within crop canopy when plants are grown under varying water levels. In a 2-yr sorghum (Sorghum bicolor L. Moench) greenhouse study, plants wer...

E(V − I) reddening values for 1123 locations in the bar region of the Large Magellanic Cloud are presented. V , I photometry of red clump stars identified in the Optical Gravitational Lensing Experiment II catalogue of LMC were used to estimate reddening. E(V − I) values were estimated as the difference between observed and the characteristic values of (V − I) for the red clump population in a ...

Context. A systematic estimation of the line of sight depth in the disk and bar regions of the Large and Small Magellanic Clouds (LMC and SMC) using red clump stars is presented. Aims. We used the red clump stars from the photometric data of the Optical Gravitational Lensing Experiment (OGLE II) survey and the Magellanic Cloud Photometric Survey (MCPS) for both the Clouds to estimate the depth....

Population supplementation programs that release captive-bred offspring into the wild to boost the size of endangered populations are now in place for many species. The use of hatcheries for supplementing salmonid populations has become particularly popular. Nevertheless, whether such programs actually increase the size of wild populations remains unclear, and predictions that supplementation f...

Fishery management complexity conspires to defeat seemingly obvious solutions to overfishing. Management may not adequately include decisions of fishers, management, and politicians. A new, simple, but acceptably complex fish population model is meshed with both fishery activities and management decision making. The population component is based on the common single stock biomass dynamic model....

The objective of this study was to investigate serum lipoprotein levels in order to assess cardiovascular disease (CVD) risk factors between fish-consuming populations and non-fish-consuming populations, as it has been speculated that fish intake reduces CVD risk. A representative sample of one thousand subjects (529 men and 471 women) were selected, with ages ranging from 20 to 70 years, from ...

Suzaku observed the Galactic center region near the Radio Arc at ∼ 20 southeast of SagittariusA. In the 18×18 field of view, we found four distinct X-ray sources: a bright star and a diffuse source associated with the star clusters in the soft band (0.5–2.0 keV), a small clump in a higher energy band (4–6 keV), and a peculiar clump in the 6.4 keV line band. The latter two clumps are located at ...

Dynamics of relativistic outflows along the rotation axis of a Kerr black hole is investigated using a simple model and the evolution of the speed of the flow relative to the ambient medium is studied. We assume that a flow clump is under the influence of the relativistic tidal force of the central source as well as the Lorentz force due to the large-scale electromagnetic field that is assumed ...

Multi slit spectroscopy at the Telescopio Nazionale Galileo was employed to measure radial velocities for 20 stars in the direction of the old open cluster Berkeley 29, the farthest known in our Galaxy. Membership information was derived for stars along all the red giant branch, in particular near its tip, and on the red clump. The sample of bona-fide cluster members was used to revise the clus...
