Modern Life Saving Survival Swimming and Water Safety

Preventing adolescent drowning: understanding water safety knowledge, attitudes and swimming ability. The effect of a short water safety intervention.

Worldwide, epidemiological data indicate that children are a high-risk group for drowning and while progress has been made in understanding toddler drownings, there is a lack of empirical evidence regarding the drowning risk and protective factors inherent for adolescents and young adults. This study used a self-report questionnaire to establish swimming and water safety knowledge and attitudes...

Life-saving and life-taking: a comment.

Sensing sugar and saving water

Water is the major factor limiting the growth and development of many land plants, and stomata, composed of two guard cells, are the chief gates controlling plants’ water loss. Many environmental and physiological stimuli control stomatal opening, but they all do so through the regulation of guard-cell osmolarity. Increased guard-cell osmolarity leads to the opening of the stomata and decreased...

Water-saving irrigation strategies affect tuber water relations and nitrogen content of potatoes

The dynamic and static deficit (DDI, SDI), partial root drying (DPRD, SPRD) and full (FI)irrigation strategies were applied in Agria and Ramos potato cultivars in a semi-arid area. FIreceived 100% of the potential evapotranspiration (ET); SDI and SPRD received 75% of ETduring the growth period; DDI and DPRD received 90% of ET in the first third, 75% of ET inthe second third and 50% of ET in the...

Uncertain lifetime, life protection, and the value of life saving.

The analytic innovation is treating life's end as uncertain, and life expectancy as partly the product of individuals' efforts to self-protect against mortality and morbidity risks. The demand for self-protection is modeled in a stochastic, life-cycle framework under alternative insurance options. The model helps explain the trend and systematic diversity in life expectancies across different p...
