The study was conducted to determine the plants preference by goats grazing at Central Darfur State, Sudan in 2016. The objective was to identify desirable plants that would assist in range rehabilitation. Five mature female goats were used to determine diet selection using the bite count technique. The total number of bites from each plant species was recorded and the selected diet and prefere...

In this paper, we first use a fuzzy preference relation with a membership function representing preference degree forcomparing two interval-valued fuzzy numbers and then utilize a relative preference relation improved from the fuzzypreference relation to rank a set of interval-valued fuzzy numbers. Since the fuzzy preference relation is a total orderingrelation that satisfies reciprocal and tra...

Preference value means livestock preference to eat some plants relative to other plants or species. Accordingly, by studying the preference values, the range managers could determine the rangelands grazing capacity to achieve the optimum performance of livestock and to guarantee the stability of rangeland ecosystem. The objective of this study was to determine the preference value of perennial ...

BACKGROUND Measures have not taken account of the relative importance patients place on various outcomes. AIMS To construct and evaluate a multidimensional, preference-weighted mental health index. METHOD Each of over 1200 patients identified the relative importance of improvement in six domains: social life, energy, work, symptoms, confusion and side-effects. A mental health index was crea...

greenhouse whitefly and two-spotted spider mite are two important pests on greenhouse crops. the polyphagous predatory mite amblyseius swirskii preys on both of these pests. in this research, predation of the predatory mite on different stages of both pests, prey stage preference of pests, prey preference and switching behavior of predator between preferred stage of greenhouse whitefly and two-...

We study the growth process among a large group of economies where consumption relative to reference determines discount factor household agents. characterize all possible balanced paths and their stability properties. The model can explain why two having similar production technologies, preferences, total productivity rates differ in labor supply behavior have diverging depending on initial co...
