Within areas of the Chihuahuan Desert dominated by honey mesquite bushes (Prosopis glandulosa), soil erosion causes open eroded patches and the formation of large coppice dunes. The airflow patterns around the dunes and through the open areas are correlated with sand flux and erosion. This study uses wind velocity simulations from the Quick Urban and Industrial Complex (QUIC) model in combinati...

Five new species, Hylaeus (Hylaeus) wuae sp. nov., H. (Hylaeus) napacus sp. nov., H. (Hylaeus) neatifrons sp. nov., H. (Hylaeus) bimaculatus sp. nov. and Hylaeus (Prosopis) ikudomei sp. nov. are described and illustrated from Yunnan, China. The diagnosis of each species is provided. In addition, Hylaeus cardioscapus Cockerell, 1924 is recorded from China for the first time.

The synthesis that is described in this study is for the preparation of silver nanoparticles of sizes ranging from 10 nm to 30 nm with a defined shape (globular), confirmed by UV-vis, SEM, STEM and DLS analysis. This simple and favorable one-step modified Tollens reaction does not require any special equipment or other stabilizing or reducing agent except for a solution of purified mesquite gum...

Archaeological and palaeoecological studies throughout the Americas have documented widespread landscape and environmental transformation during the pre-Columbian era. The highly dynamic Formative (or Neolithic) period in northern Chile (ca. 3700-1550 yr BP) brought about the local establishment of agriculture, introduction of new crops (maize, quinoa, manioc, beans, etc.) along with a major po...

composting of waste plant materials and its use in agriculture and landscape sites is an environmental friendly way of reducing waste material and conserving the environment. in this perspectives a survey has been performed at the dubai based international center for biosaline agriculture to compost the plants based waste material (lawn cuttings-grass) to compost. the material was inoculated wi...

Biological invasions are complex processes requiring coordinated and spatially targeted management. This study assessed spatiotemporal trajectories determinants of Prosopis cover in Baringo County, Kenya. Land data for every seven years between 1988 2016 revealed the presence Prosopis. We tested trajectory clusters using spatial autocorrelation overlaid categories with landscape features. Gener...

In this paper, a crude methanolic extract from the stem bark of Prosopis cineraria, a plant native of Pakistan, was tested for its possible presence of spasmolytic, bronchodilator, and vasodilator activities in an attempt to validate some of its folkloric uses. Moreover, attempts were made to provide plausible explanations of the observed biological activities. The extract caused relaxation of ...

background lead is a toxic metal with a poor electrical conductivity. this metal can be hazardous and poisonous even in low concentrations. objectives the objective of this study is the evaluation of prosopis mimosaceae sawdust as a low-cost adsorbent for removal of the lead from effluents. materials and methods the experiment was conducted in a batch system and the effect of ph, the amount of ...
