Effect of the inclusion of lemon leaves and rice straw by-products in the diet of dairy goats on the quality characteristics of milk and matured cheeses

[EN] The effect of the dietary inclusion of lemon leaves and rice straw by-products on the quality characteristics of goats' milk and cheese was evaluated. Twenty-six Murciano-Granadina goats were used in a crossover design experiment; milk from each experimental group was collected to produce 60-days matured cheeses. Fat and dry matter content was higher in milk and cheeses from the diet containing by-products; medium-chain fatty acids and total free fatty acids were lower. Triangle tests revealed significant differences in the organoleptic characteristics of the cheeses between diets. However, when sensory attributes differentiating cheeses were evaluated individually, differences did not become significant. The inclusion of lemon leaves and rice straw in balanced diets with soya oil could be beneficial, as it does not appear to adversely affect the quality of milk and related mature cheeses, contributing to the reduction of the cost of the diet and the recycling of agricultural by-products.

Racial Stratification in Self-Rated Health Among Black Mexicans and White Mexicans

How do Mexicans of distinct racial backgrounds fit into the recognized patterns of racial health disparities? We conduct regression analyses using data from the 2000-2017 National Health Interview Survey to determine if Mexicans who self-identify as White or Black have a relative advantage or disadvantage in self-rated health in relation to Non-Hispanic (NH) Whites and Blacks in the U.S. Our results indicate that both Black Mexicans and White Mexicans have a significant disadvantage in relation to NH-Whites while White Mexicans have a slight advantage in relation to both NH-Blacks and Black Mexicans. Overall, our results suggest that studying health outcomes among Hispanics without considering race may mask inequalities not observed in the aggregate

The legacy of 1300 years of land use in Jamaica

Despite decades of archaeological research on Jamaica, little is known about how settlers influenced landscape change on the island over time. Here, we examine the impact of human occupation through a multi-proxy approach using phytolith, charcoal, and stratigraphic analyses. White Marl was a continuously inhabited village settlement (ca. 1050–450 cal yrs BP) with large mounded midden areas, precolonial house structures, and human landscape management practices. We have shown that the local vegetation at White Marl was directly affected by human settlement through the use of agroforestry and burning, and suggest that fire was used to modify vegetation. Manioc phytoliths were found throughout human occupation and are broadly associated with increases in evidence for burning, suggesting fire was used to modify the landscape and clear vegetation for crop cultivation. The phytolith assemblages relate to three distinct temporal vegetation phases: (1) the earliest occupation dominated by arboreal vegetation (pre-ca. 870 cal yrs BP); (2) a transition to palm-dominated vegetation (ca. 870–670 cal yrs BP); and (3) the latest occupation representing European colonization associated with a more open, grass-dominated landscape (after ca. 670 cal yrs BP). These transitions occur independent of changes in paleoclimate records, suggesting humans were the dominant driver of vegetation change.Introduction Archaeological context Archaeobotany in Jamaica The White Marl site Materials and methods - Sampling, stratigraphic analysis, and recording - Phytoliths - Phytolith extraction - Phytolith identification, counting, and quantification - Charcoal extraction and quantification Results - Vegetation phase 1: Arboreal-dominated canopy - Vegetation phase 2: Palm-dominated canopy - Vegetation phase 3: Open grassland-dominated landscape - Crops - Burning indicators - Vegetation changes and climate Discussion Conclusio

The second data release of the INT Photometric Ha Survey of the Northern Galactic Plane (IPHAS DR2)

The INT/WFC Photometric Hα Survey of the Northern Galactic Plane (IPHAS) is a 1800 deg2 imaging survey covering Galactic latitudes |b| < 5° and longitudes ℓ = 30°–215° in the r, i, and Hα filters using the Wide Field Camera (WFC) on the 2.5-m Isaac Newton Telescope (INT) in La Palma. We present the first quality-controlled and globally calibrated source catalogue derived from the survey, providing single-epoch photometry for 219 million unique sources across 92 per cent of the footprint. The observations were carried out between 2003 and 2012 at a median seeing of 1.1 arcsec (sampled at 0.33 arcsec pixel−1) and to a mean 5σ depth of 21.2 (r), 20.0 (i), and 20.3 (Hα) in the Vega magnitude system. We explain the data reduction and quality control procedures, describe and test the global re-calibration, and detail the construction of the new catalogue. We show that the new calibration is accurate to 0.03 mag (root mean square) and recommend a series of quality criteria to select accurate data from the catalogue. Finally, we demonstrate the ability of the catalogue's unique (r − Hα, r − i) diagram to (i) characterize stellar populations and extinction regimes towards different Galactic sightlines and (ii) select and quantify Hα emission-line objects. IPHAS is the first survey to offer comprehensive CCD photometry of point sources across the Galactic plane at visible wavelengths, providing the much-needed counterpart to recent infrared surveys

Aridisols of Spain

6 Pags.- 2 Tabls.This paper reviews the distribution and classification of Spanish Aridisols and discusses some taxonomic problems and major management practices. Little literature is available about Spanish Aridisols. Most of the information contained in this Daper comes from soil maps and from the authors unpublished data. The discussion covers the update of Soil Taxonomy, the unsuitability of Newhall's method for some Spanish Mediterranean areas, and the taxonomic status of the gypsiferous soils. Many of the soils classified as Aridisols (S.S.S., 1975) are now distributed into several Orders because the EC criterion has been dropped at this hierarchic level. Recently, a new method for soil moisture regime calculation has been developed in Spain. This method improves the delineation of the aridic regions. Micromorphology provides a better knowledge of hypsiferous soils, and two kinds of gypsic horizons have been identified. Apart from marginal uses. the management of Spanish Aridisols is based on water supply and/or water saving and on taking advantage of early cropping. The following conclusions can be made: (i) the new model of soil moisture regime calculations can be applied to the presumed aridic areas of Spain and calibrated with soil moisture measurements in the field, (ii) the inclusion of gypsiferous soils into three Orders disagees with their distinct morphology and behavior, (iii) refinement in the gypsic horizon definition is needed to link microscopic features and field criteria, and (iv) both old and new management practices in Aridisols must be reported in detail for improvement, the adaptation of new technologies, and extension of management practices to new areas.Peer reviewe
