Dietary patterns and bone mineral status in young adults: the Northern Ireland Young Hearts Project
Studies of individual nutrients or foods have revealed much about dietary influences on bone. Multiple food or nutrient approaches; such as dietary pattern analysis; could offer further insight but research is limited and largely confined to older adults. We examined the relationship between dietary patterns; obtained by a posteriori and a priori methods; and bone […]
Almond tree canopy temperature reveals intra-crown variability that is water stress-dependent
Tree water status is often characterized by measuring a few leaves and it is not known to what extent such measurements represent the tree as a whole. We present an assessment of the intra-crown temperature variability and its relationship with water status in two almond cultivars. High-resolution imagery was acquired on 30 June 2009 at […]
Snacking is associated with overall diet quality among adults
Snacking occasions are considered to contribute little more than energy to the diet; however; few studies have examined the role of snacking on overall diet quality. The purpose of this study was to examine the association between snacking frequency and overall diet quality. This study included 11;209 adults aged 20 years and older who participated […]
Development of a system to produce maps of agricultural profit on a continental scale: An example for Australia
Policy makers in the agricultural sector are confronted with challenges which might drive land use change and ultimately agricultural profitability to a substantial degree. The challenges include questions around climate variability; demographic changes; use of land for bio-fuel production and ensuring an increase in food production. As profitability triggers many agri-business decisions; knowledge about the […]
Determination of size and shape features of walnut (Juglans regia L.) cultivars using image processing
The dimensions; mass; and shape are the most commonly measured physical properties of fruits. The size and shape features of 10 common walnut (Juglans regia L.) cultivars grown in Turkey were investigated using an image processing technique. The walnut cultivars produced nuts longer than wide and wider than thick in shape except cvs. Bursa-95; Hartley; […]
Selection of intermittent drought tolerant lines across years and locations in the reference collection of groundnut (Arachis hypogaea L.)
Intermittent drought is the most important yield limiting factor affecting groundnut (Arachis hypogaea L.) production in rain-fed regions of Sub-Saharan Africa and Asia. Improvement of crop adaptation to drought is needed and this starts by having a thorough assessment of a large and representative set of germplasm. In this study; 247 lines belonging to the […]
The regeneration of Brazil nut trees in relation to nut harvest intensity in the Trombetas River valley of Northern Amazonia; Brazil
This study examined the harvest of nuts from Brazil nut trees (Bertholletia excelsa) in the valley of the Trombetas River; a 760-km tributary on the northern bank of the Amazon River in Pará state; Brazil. The region is characterised by old-growth forests dominated by Brazil nut trees. Demographic data were obtained from twenty-five 50-m à […]
Spatial dynamics of cone production in Mediterranean climates: A case study of Pinus pinea L. in Portugal
Seed production of trees is key to natural regeneration of forests and to successful conservation management. Despite its importance no spatially explicit analyses of seed production have so far been carried out in this important field. Analyses like these are particularly important in areas with regular summer droughts. We used Pinus pinea L. as a […]
Effects of temperature and packaging atmosphere on total antioxidants and colour of walnut (Juglans regia L.) kernels during storage
The effects of cultivar and storage conditions (time; temperature and O2 availability) on total phenolics (TP); total antioxidant capacity (TAC) and colour in walnut kernels of three cultivars (Chandler; Hartley and Ioli) were investigated. Harvested walnuts were dried at 36 °C for 24 h; packaged in polyethylene||polyamide pouches flushed with dry air or N2 or […]
Preparation of fatty acid methyl esters from hazelnut; high-oleic peanut and walnut oils and evaluation as biodiesel
Refined hazelnut; walnut and high-oleic peanut oils were converted into fatty acid methyl esters using catalytic sodium methoxide and evaluated as potential biodiesel fuels. These feedstocks were of interest due to their lipid production potentials (780Â1780 L ha-1 yr-1) and suitability for marginal lands. Methyl oleate was the principal constituent identified in hazelnut (HME; 76.9%) […]
