Abstract The use of organic waste as components substrate to produce fruit plantlets provides alternative materials, easily available and low cost. aim this work was evaluate the effect biofertilization with cow urine on growth cupuaçu plants (Theobroma grandiflorum) in an production system. A factorial experiment conducted a completely randomized design 12 replications including four types sub...

This paper is about the economic theory of biodiversity preservation. A cost-effectiveness methodology is constructed, which results in a particular formula that can be used as a criterion to rank projects. The ranking criterion is sufficiently operational to be useful in suggesting what to look at when determining actual conservation priorities among endangered species. At the same time, the f...

simulations. ARK is built upon a physical-world metaphor: all objects have an image, a position, a velocity, and can experience forces. Users manipulate objects with a mouse-operated "hand" which enables them to carry and throw objects, to press buttons, and to operate sliders. The interface features are discussed in light of a general user interface tension between literalism and magic. Litera...

Transgenic mice with cardiac specific overexpression of -adrenergic receptor kinase-1 ( ARK-1) exhibit reduced contractility in the presence of adrenergic stimulation. However, whether contractility is altered in the absence of exogenous agonist is not clear. Effects of ARK-1 overexpression on contraction were examined in mouse ventricular myocytes, studied at 37°C, in the absence of adrenergic...

As part of the Ark Encounter Project at Answers in Genesis, a research effort has been initiated to provide information necessary for the best possible reconstruction of the animal kinds preserved on the Ark. This initial paper outlines the basic rationale that will be used and the underlying justification for it. The biblical text provides strong evidence for each kind being a reproductive uni...

This paper describes the German-English translation system developed by the ARK research group at Carnegie Mellon University for the Sixth Workshop on Machine Translation (WMT11). We present the results of several modeling and training improvements to our core hierarchical phrase-based translation system, including: feature engineering to improve modeling of the derivation structure of translat...

Many biodiversity researchers have responded to the financial constraints faced by policy makers to develop models based upon the “Noah’s Ark” metaphor, implying that society can save only a limited amount of biodiversity. Unfortunately, as Herman Daly (Land Economics, 1991) pointed out, such microeconomic rules can allow an ark to sink albeit in some optimal fashion. So, I step back to look at...
