1. How do CO2 and radon gases affect groundwater mining in the Canary Islands?
Abstract Water galleries are mines that seek to supply drinkable and irrigation water from the aquifer, in order to meet the demand for water in the Canary Islands. This sort of work entails a series of health risks in the form of gases. This document compiles three different studies on the gases that can be found in water galleries in the Canary Islands, ha

6. TECHNICAL AND ECONOMIC FEASIBILITY OF USING A VARIABLE-FREQUENCY DRIVE IN MICRO-IRRIGATION SYSTEMS
ABSTRACT Irrigation is essential for the development of crops in regions with scarcity or irregular rainfall distribution, enabling high productivity. However, the use of water resources and electrical energy leads to a concern with irrigation efficiency. Pressure demand varies during the operations of irrigation systems and the appropriate pressure can be r

7. MINI-CUTTINGS TECHNIQUE FOR VEGETATIVE PROPAGATION OF Dalbergia nigra
ABSTRACT The usual propagation method for Dalbergia nigra is via seedings; however, the seasonal supply has a variable quantity of seeds which limits the continuous production of seedlings. Therefore, the objective of this study was to establish a vegetative propagation protocol via mini-cuttings technique for D. nigra from juvenile shoots obtained from seed

8. A água e o fim da ambição na saúde global, c.1970-1990
Resumo Crescimento econômico e boa saúde dependem de acesso a saneamento e água limpa. Assim, o Banco Mundial, a Organização Mundial da Saúde (OMS) e outros órgãos, a partir do início da década de 1970, inauguraram um período de contínuo interesse no desenvolvimento de ambos para bilhões de pessoas desprovidas de tais necessidades. Durante a dé

9. DIRECT CONNECTION PHOTOVOLTAIC SYSTEM IN MULTI-MOTOR APPLICATION FOR THE RURAL SECTOR
ABSTRACT Photovoltaic pumping systems equipped with variable speed drive have been consolidated as an alternative for water supply in rural locations where energy services are unavailable. Such systems are of the direct connection type and, therefore, it is likely that their operation occurs in two situations: when energy is available and when the reservoir

10. Budbreak induction in kiwifruit vines cultivated in an organic system by the biological method of single node cutting
ABSTRACT Kiwifruit vines are an alternative approach to diversify Brazilian fruit farming because of the low supply and increase in the demand for their fruits. Hydrogenated cyanamide, which is the most common rest-breaking agent, is highly toxic and its use is not allowed in organic production systems. This study aimed at evaluating the efficiency of altern
