The links between childhood eating behaviours and parental feeding practices are well-established in younger children, but there is a lack of research examining these variables in a preadolescent age group, particularly from the child's perspective, and longitudinally. This study firstly aimed to examine the continuity and stability of preadolescent perceptions of their parents' controlling fee...
AIM To develop affordable, appropriate, and nutritious recipes based on local food resources and dietary practices that have the potential to improve infant feeding practices. METHODS We carried out a mixed methods study following the World Health Organization's evaluation guidelines on the promotion of child feeding. We recruited caregivers with children aged 6-23 months in Wuyi County, Hebe...
The aim of this paper is through a qualitative study to determine how efficient academic entrepreneurship training occurs in an academic environment and how these programmes are structured and organised. Data from 20 different university training programmes at 12 European countries were analysed. We used a check-list to gather information on these items: Promoter, programmes, target groups, key...
The impact of military training activities (primarily foot traffic) on soils and vegetation was assessed at the United States Air Force Academy, Colorado, USA. In May-June 1998 after 2 years of intensive training use, mean bulk densities of the top 6 cm of soil in the high-use site (1.37 g/cm(3)) and moderate-use site (1.30 g/cm(3)) were significantly different from bulk density of the referenc...
The effect of different tillage practices on soil hydraulic properties was studied in a mature, drip irrigated apricot orchard with a 7% slope, in Murcia (SE Spain). The soil had a loamy texture. Three soil tillage treatments were applied between the rows of trees: 1) control treatment (non-tilled, although weeds were cut to ground level using a blade attached to a tractor following the common ...
infiltration is a complex process that changed by initial moisture and water head on the soil surface. the main objective of this study was to estimate the coefficients of infiltration equations, kostiakov-lewis, philip and horton, and evaluate the sensitivity of these equations and their coefficients under various initial conditions (initial moisture soil) and boundary (water head on soil surf...
the aim of this study was to identify and prioritize the risky behaviors and explore the newly emerging pi related to egyptian habits that may lead to hcv transmission.from january 2011 until january 2012, a case control study matched on socio demographic factors was conducted comparing 540 hepatitis c patients and their contacts who were hcv serologically negative (102 subjects). they were ran...
In response to urban pluvial flooding and pollution, the Chinese government proposed a “sponge city” policy in 2013 that aims improve stormwater management promote sustainable development. However, at present, sponge city construction is still its exploratory stage. It not clear which models are capable of simulating six key processes (i.e., “retention,” “infiltration,” “storage,” “purification...
plant cover is one of the most important factors affecting infiltration rate of water into the soil and decreasing runoff. distribution of plants in arid and semi-arid areas is almost patchy and form different patterns. one of the fascinating patterns is ring-shaped growth pattern. ring patterns of varying size are formed by clonally reproducing grasses, sedges and even shrubs growing in resour...
The relative reduction in potential ground-water contamination due to pesticides at several sites in Utah was determined by comparing alternative irrigation system designs, water management practices and pesticides. Alternative sprinkler irrigation distribution coefficients were used to estimate infiltration depths. The movement of pesticides through soils following sprinkler irrigations was si...
