Supply Equipment

Having access to a safe water supply is important to improve a person's quality of life. We examine the relationship between the influence of water availability on monthly household expenditures (the dependent variable) and independent variables such as household characteristics, tank size, usage instructions and post-construction guidance, including the management of water-related health risks. The sample consisted of 301 respondents who harvest rainwater in Uganda. A multiple regression analysis was used to analyse the data. The findings show that post-construction guidance and tank size were significant variables. This study suggests the need for a follow-up to improve health after the installation of water supply equipment, i.e., to provide information about water risks, foster reading norms and facilitate the availability and affordability of information sources, e.g., subsidised newspapers and information support devices (computers). Additionally, this study shows the possibility of increased savings due to reduced expenditures on water from vendors and the management of water-related health risks caused by a water shortage, e.g., dehydration. Overall, the study reveals two possible ways to advance policy and health in developing countries: (1) ensuring sufficient post-construction guidance for all water resources; and (2) ensuring a sustainable supply of adequate safe water in households.

Lower Stem

In very young apple (Malus domestica Borkh.) seedlings, cotyledon dry weight decreased during the 14-day period following cotyledon separation and development. Removal of both cotyledons at the time of cotyledon separation significantly reduced subsequent seedling development as measured by leaf area and leaf fresh and dry weights, but it did not alter established 14C-labelled photosynthate transport patterns. Cotyledon removal from seedlings with fully expanded cotyledons and four unfolded expanding true leaves did not affect subsequent seedling growth. Removal of one cotyledon in very young seedlings reduced retention and export and increased apparent metabolism of 14C-labelled photosynthate. Removal of one cotyledon in older seedlings to which 14CO2 was fed to the first true leaf did not influence retention, export, or metabolism of the 14C-labelled photosynthate in the fed leaf. In the early stages of seedling growth, assimilates were directed mainly to the lower stem and root system, then to the shoot apex and immature leaves, and finally again to the root system as the first true leaf assumed the function of supplying assimilates during cotyledonary senescence.
