BACKGROUND Welfare dependence and low work participation among young people have raised concern in many European countries. Reading and writing difficulties (RWD) might make young people vulnerable to work integration problems and welfare dependence through negative influences on education and health. Our main objective of this study was to examine if RWD in adolescence affected the risk of wel...

Water stress is the most important abiotic stress in crop production. Silicium (Si) is the second most abundant element in the soil with beneficial effects on plant tolerance to biotic and abiotic stresses. In order to evaluate the effect of this element in increasing tolerance to water deficit in wheat, a factorial experiment was conducted based on a completely randomized design with three rep...

BACKGROUND Randomized controlled trials (RCTs) are the 'gold standard' in the generation of drug efficacy and safety evidence. However, enrolment criteria, timelines and atypical comparators of RCTs limit their relevance to standard clinical practice. DISCUSSION Real-world data (RWD) provide longitudinal information on the comparative effectiveness and tolerability of drugs, as well as their ...

wild jujube, ziziphus lotus, is a multipurpose xerophytic shrub of the rhamnaceae family widely distributed in arid and semi-arid regions of tunisia, where it occupies most soil types. the fruit is the edible part of the plant by local population. the reintroduction of this shrub requires the control of its multiplication in response to water shortage. this study aims to evaluate growth and wat...

Among the crops, cereals have been special important and triticale is the most successful man made cereal. In present research, water deficit stress effects on 19 triticale genotypes (X Triticosecale wittmack) and two wheat cultivars (Triticum aestivum), Shiraz (sensitive to water deficit stress) and Kavir (tolerant to water deficit stress) were tested. Therefore, two separate field experiments...

Drought stress is one of the most important factors threatening the growth and development of ornamental plants around the world. Clearly, the use of active ingredients that increase drought resistance in plants is very important to reduce the economic losses of ornamental plants in landscapes. For this aim, a study was conducted to evaluate the effects of sodium hydrochulfide on Amaranthus pla...

To understand how temperate coexisting tree species respond to water deficit, the seedlings of two coexisting species, Phellodendron amurense Rupr. And Fraxinus mandshurica Rupr., were transplanted into plastic flowerpots. Three water deficit treatments were used, W1 (60-90% field moisture capacity), W2 (40-60% field moisture capacity), and naturally occurring precipitation (CK), with the aim o...
