Agricultural expansion in Sub-Saharan Africa is characterized by different farm ages smallholder communities. This study investigated changes microbial indices broadly (i) at the reconnaissance survey level four agro-ecological zones and (ii) farms forest (Dompem) forest–savanna transition (Adansam) zones, as influenced duration of cultivation. Soils from one-year (first cultivation cleared for...

Recent efforts by the United States Department of the Interior (DOI) have the potential to make climate zones the basic geographic units guiding monitoring and resource management programs in the western U.S. We evaluated a new National Park Service approach for delineating climate zones that will likely be a model for other DOI agencies. Using the test case of the Greater Yellowstone Area in W...

We revisit several aspects of the interaction self-gravitating, slowly varying sources with their own emitted radiation within context post-Newtonian approximation to General Relativity. discuss and clarify choice boundary conditions Green's functions used determine conservative potentials, interplay between so-called near far zones, as well relation zone ultra-violet divergences power. Both co...

Tension zones are maintained by the interaction between selection against hybrids and dispersal of individuals. Investigating multiple hybrid zones within a single species provides the opportunity to examine differences in zone structure on a background of differences in extrinsic factors (e.g., age of the zone, ecology) or intrinsic factors (e.g., chromosomes). The New Zealand tree weta Hemide...

Identifying zones and movement patterns of people is crucial to understanding adjacent regions and the relationship in urban areas. Most previous studies addressed zones or movement patterns separately without analysing simultaneously the two issues. In this paper, we propose an integrated approach to discover directly both zones and movement patterns among the zones, referred to as movement pa...

The aim of this work is to justify mathematically the derivation of a viscous free/congested zones two–phase model from the isentropic compressible Navier-Stokes equations with a singular pressure playing the role of a barrier. Titre et résumé en Français. Modèle bi-phasique gérant zones libres/zones congestionnées comme limite singulière d’un système de Navier-Stokes compressible. Le but de ce...

Despite intense investigation, human replication origins and termini remain elusive. Existing data have shown strong discrepancies. Here we sequenced highly purified Okazaki fragments from two cell types and, for the first time, quantitated replication fork directionality and delineated initiation and termination zones genome-wide. Replication initiates stochastically, primarily within non-tran...

Studies were performed to evaluate the validity of using the radioactive microsphere technique to measure regional blood flow in the renal cortex. A technique was developed in which the renal cortex was divided into four equal zones, and the fractional and absolute distribution of blood flow in these zones was determined. It was consistently found that approximately 70% of the renal blood flow ...
