BACKGROUND: Suitable and useful usage of different kind of fertilizers is the main way for reformation and potential of soil fertility and increasing of crops yield. Microelements are the critical elements for plants; also play the important role in crop productivity where it is used in low rate. Optimum plant nutrition and maximum yield is achieved when nutrient elements are a...

Based on the long-term, demographic forecast, Hungary faces a significant population loss. This paper examines continuing low level of Hungarian fertility, as well marked decline due to out-migration beginning in mid-2000s. First, I will discuss role governmental family policies play halting fertility before 1989, post-transitional period 1960-1980 and past thirty years since 1989. Second, this...

We explore the implications of three basic and intuitive axioms for income redistribution problems: continuity, no transfer paradox stability. The combination characterizes in two-agent case a large family rules, which we call threshold rules. For each level total society, is considered agent. It impossible both agents to be below their respective thresholds. If an agent’s threshold, difference...

• We characterize the optimal shape of non-linear income and wealth taxes. Our model reproduces distribution in United States a dynamic general equilibrium setting. find that uniform flat tax on capital labor combined with lumpsum transfer is nearly optimal. The incremental welfare gains from steeper marginal taxes are small, especially when planner has strong preference for redistribution What...

conclusions pressure support ventilation, but not spontaneous breathing, induces a significant redistribution of ventilation towards the ventral region. the sensitivity of the support trigger appears to influence the distribution of ventilation only during the early phase of inspiration. background in supine position, pressure support ventilation causes a redistribution of ventilation towards t...
