A combination of grazing incidence X-ray reflection/diffraction (GIXR/GIXD) and atomic force microscopy have been used to study the 3D structure in cadmium arachidate (CdA) and single phase zinc arachidate (ZnA) LB multilayers. The CdA multilayers have an ideal close packed herringbone structure. The molecules have a non-centred in-plane arrangement with specific orientational relation between ...

The surface of the biomass monitoring is blocked rotational grazing land prerequisite for high scores (GF - 1) satellite multispectral image and artificial index test, using ENVI software GF1 or GF6 data (radiation calibration atmospheric correction RPC orthographical correction), then calculate vegetation (NDVI), NDVI can detect growth status, coverage eliminate part radiation error manual col...

The present study was to evaluate the weight gain of bovinesin three animal loads with two grazing systems and levels grazing, furthermore botanic composition secondary vegetation areas. carried out during years, in first year, used were 0.25, 0.50 0.75 unit per hectare (AU/ha).The which animals evaluated 8 years old. Botanic determined by transects at beginning experiment. rotational alternate...

Abstract The supplementary feeding costs of small ruminants can be substantial when there is not much vegetation available for grazing or browsing. However, such have been reported well and the strategies to minimize them discussed enough. objective this study was quantify involved in supplementing under grazing-based production systems. Grazing studies were conducted from July October 2021 (88...

Rotational grazing studies have produced mixed results related to animal performance (weight gain), which has contributed producer uncertainty regarding management decisions. To enhance decision-support for producers, we improved algorithms in the Agricultural Policy/Environmental eXtender (APEX) model better represent cattle weight gain real-world rangeland conditions under two strategies. Sim...

A grazing study was initiated in April 2000 and continued through three calving and weaning cycles (ending July 2003) to investigate the effects of rotational grazing management (twice monthly [2M] vs. twice weekly [2W]) and weaning date (mid-April [EARLY] vs. early June [LATE]) on production of fall-calving cow-calf pairs (495 +/- 9.6 kg initial BW) grazing Neotyphodium coenophialum-infected t...

Modifications in the structure of grasslands have been responsible for decline several avian species due to a reduced quality available habitat. Currently, applications herbicide glyphosate introduced promote winter forage production Flooding Pampas Argentina. Rotational grazing has another technique used production. Here, we evaluated different managements cattle systems on richness, compositi...

Oak (Quercus spp.) savanna, characterized by widely scattered oaks with an understory of prairie and other specialized species, is one of the most endangered native ecosystems in North America (Nuzzo 1986, Packard and MuteI1 997). The absence of grazing and burning along with the in troduction of tillage agriculture are key factors for the loss of this ecosystem. Our objective was to determine ...
