Exploring the silvicultural and economic viability of gap cutting in Mediterranean softwood plantations

引用

Forestry Studies in China 2012年第1期14卷 63-69页

作者： Roberto MERCURIO raffaele spinelli Department of Agricultural and Forest Systems Management Mediterranean UniversityFeo di Vito89122 Reggio CalabriaItaly CNR IVALSA Via Madonna del Piano 10Sesto Fiorentino (FI)Italy

Gap cutting consists of the removal of all trees growing on a small surface, varying in size from 200 to 600 m2. In Italy, gap cutting has been successfully tested for introducing the natural regeneration of native species into softwood plantations, thus ac- celerating the transition towards climax hardwood stands. Depending on plantation types and conditions, gap cutting should be start- ed at an age between 70 and 80 years and the system should include at least 12 to 15 gaps, in order to produce enough wood to cover costs. Generally, natural regeneration is firmly established within 5-7 years from treatment. Gap cutting also offers superior results to selection thinning, the latter producing about 35% less value and incurring 25% to 30% more costs. As for all regeneration cuts, the success of gap cutting depends on wildlife control in order to prevent extensive damage to the regeneration.

Performance of a small-scale chipper for professional rural contractors

Forestry Studies in China 2013年第3期15卷 206-213页

作者： raffaele spinelli Natascia MAGAGNOTTI CNR IVALSA Via Madonna del Piano 10 I-50019 Sesto Fiorentino (FI)Italy CNR IVALSA Via Biasi 75 S. Michele all’Adige (TN)Italy

The study determined the productivity, fuel consumption and product quality obtained with a new tractor OWered drum chipper, designed to reduce the gap between industrial chippers and small-scale chippers. The machine as tested with poplar logs and beech slabs, considered as representative of the raw material commonly used for ergy wood production. After accounting for accessory work and delays, productivity of green chips ranged between and 6 tons per scheduled machine hour, which was very good for a tractor-powered unit. Specific fuel consumption f oven-dry chips varied between 2.5 and 3.0 L per ton, or 0.6 L per m_3. These figures compared favourably with those btained from previous studies of both smaller and bigger chippers. Chip quality was very good. Samples contained no versize particles, qualifying for use in small-scale plants. The average size of beech chips was significantly larger than r poplar chips, possibly due to the higher strength of beech wood.

Spontaneous Luminescence Background in Living Nu/Nu Mice

Advances in Molecular Imaging 2012年第2期2卷 5-11页

作者： Federico Boschi Antonello E spinelli Laura Calderan Andrea Sbarbati Department of Neurological Neuropsychological Morphological and Motor Sciences Section of Anatomy and Histology University of Verona Verona Italy Medical Physics Department S. Raffaele Scientific Institute Milan Italy

Spontaneous light emission from living animals can overcome the investigated light signals in small animal luminescence imaging. Despite autofluorescence emission is well studied the spontaneous luminescence background is less known and its importance is growing due to the new born imaging techniques like Cerenkov Luminescence Imaging and Radionuclide Luminescence Imaging in which faint sources are often involved. In order to investigate the spontaneous emission we studied the background luminescence in vivo from health Nu/Nu mice in optical imaging acquisitions and we related it with the optical properties of the diet of the animals. In particular luminescence images of mice feed with normal diet used in animal facilities were acquired using a commercial optical imager. The intensity and the spectral features of the luminescence emission from the animal surface after sunshine exposition and after normal lighting laboratory conditions were measured. The same was done with the pellets of food used to feed the animals. We found a background emission from the entire animal surface and localized light sources in the abdominal/lumbar region. Their intensity can be modulated by the light exposition of the animals before the imaging session and decreases along the time when they are put in darkness. The comparison of the luminescence time decay of animals and pellets suggests that the light sources are related to the persistent luminescence of the molecules contained in the food. So ambient exposure before imaging is important for luminescence imaging in order to keep down the background. The optical properties of food are also important and it necessary to check them before to feed the animals not only in fluorescence imaging but also in luminescence imaging.
