The USDA, Forest Service, Forest Products Lab funds several grants each year for the purpose of studying woody biomass utilization. One selected project proposed removing small diameter stems and unmerchantable woody material from National Forest lands and delivering it to a coal-fired power plant in Alabama for energy conversion. The Alabama Power Company will test the utilization of the woody...

A 34 year old sawmill maintenance engineer developed a dry cough that was associated with widespread wheezes and crackles in his lungs. His symptoms worsened, with work related lethargy, fever, and breathlessness, and the loss of a stone in weight. At that time, while still at work, he had a neutrophil leucocytosis and increased concentration of gamma globulins. When seen subsequently some two ...

The development of renewable alternatives to fossil carbon–based transportation fuels has become an urgent national priority. One of the most promising options for nearterm, commercial-scale deployment is biofuel from lignocellulosic biomass (wood chips, grasses, cornstalks, and other inedible plant-based materials). Additionally, biological systems offer multiple paths to diverse bioenergy pro...

The tree stability-assessment methodology currently used in Italian cities initially follows a visual analysis of individual trees, followed by an evaluation of the internal state using different instruments that are often invasive, expensive, or cannot be effectively used in the urban environment. Moreover, many of these instruments do not provide an adequate evaluation of decay that occurs in...

     Mulches are relatively new landscape components and are becoming recognized for their environmental and aesthetic outcomes on urban landscapes especially in arid environments. However, the effects of mulches on landscape plants have not been extensively discussed. This study examined the effects of organic and inorganic mulches on the performance of a widely used herbaceous drought toleran...
