An experiment was conducted to study the effects of lamtoro (Leucaena leucocephala) leaf supplementation in fermented kumpai grass (Hymenachne amplexia calis) based rations on the productivity of Bali cattle. Variables measured were dry matter and organic matter intakes, nutrient digestibility (dry matter, organic matter, crude protein, and crude fiber), body weight gain, and feed efficiency. T...

We regret to record the death of Dr. P. P. Johnson, of Yatton, .after a long and painful illness, borne with much fortitude. Dr. Johnson was 57 years of age, and was educated at Sedbergh, afterwards proceeding to Edinburgh University, where he took his degree in 1877. He practised for over nine years at Littleborough, in Lancashire, and for a short time in Starbotton, Yorkshire, and came to Yat...

everywhere, as it has done across Europe. Even in France, which competes with Ireland for the title of the EU’s most fertile member state, the total fertility rate dropped below reproduction level last year. Other European countries, including Germany, are most worried about how to raise it to get closer to a steady state and save the provisions for the elderly from collapse. The threat of an e...

The Johnson-Neyman technique is a statistical tool used most frequently in educational and psychological applications. This paper starts by briefly reviewing the JohnsonNeyman technique and suggesting when it should and should not be used; then several different modifications and extensions of the Johnson-Neyman technique, all of them conceptually simple, are proposed. The close relation betwee...

organisation KuzeyDog ̆a has for the past few years led studies of the carnivores in northeastern Turkey. With the first wolf-tracking project in Turkey, the research showed that these predators move much more widely than the confines of the protected areas. Within just two months they covered an area that was 13 times larger than the national park where they were caught and fitted with GPS/GSM ...

527 INTRODUCTION Native forest insects are the greatest forces of change in forest ecosystems of North America. In aggregate, insect disturbances affect an area that is almost 45 times as great as that affected by fire, resulting in an economic impact nearly five times as great (Dale et al., 2001). Of these natural agents of ecosystem disturbance and change, the bark beetles are the most obviou...

Since grass is very abundant on the Earth’s surface, it is an important element of natural 3D scenes. Real-time realistic rendering of grass has always been difficult due to the huge number of grass blades. Overcoming this geometric complexity usually requires many coarse approximations to provide interactive frame rates. However, the performance comes at the cost of poor lighting quality and l...

Grass pollen is the main cause of hay fever and allergic asthma in warm temperate climates during summer. The aim of this study was to determine the content of group 5 major allergens in pollen grains of agriculturally important grass species/cultivars. For each cultivar flowering dates and pollen production of cut anthers were observed in the field and in a climate chamber, respectively. An EL...

In this study, the toxicity of endosulfan sulfate, the primary degradation product of the insecticide endosulfan, was determined in three life stages of the grass shrimp (Palaemonetes pugio). After 96 h exposure to endosulfan sulfate, the grass shrimp adult LC50 was 0.86 microg/L (95% CI 0.56-1.31), the grass shrimp larvae LC50 was 1.64 microg/L (95% CI 1.09-2.47) and the grass shrimp embryo LC...
