Abstract:
Tree species are predominantly found throughout our surrounding environment. They hold significant economic and ecological importance for us. However, it is noticeable that most research focuses on commercial crops, aiming to enhance their production by mitigating the adverse effects of pathogens. In contrast, naturally growing trees receive less attention than commercially cultivated crops. Similar to crops, trees also face adverse conditions due to surrounding pathogens. As a result, they compromise their healthy growth and survivability rates. In the present study, we encountered several in

Abstract:
Abstract A new taper model was developed based on the switching taper model of Valentine and Gregoire; the most substantial changes were reformulation to incorporate estimated join points and modification of a switching function. Random-effects parameters were included that account for within-tree correlations and allow for customized calibration to each individual tree. The new model was applied to 19 species groups from data collected on 2,448 trees across the northeastern United States. A comparison of fit statistics showed considerable improvement for the new model. The residuals occurred

To support the tree growing by farmers, it is essential to understand the factors that influence commercial tree growing. The findings of a study to assess the current state of on-farm tree planting and the key variables influencing adoption of commercial tree growing on farms are reported in this paper.

The rapid expansion and integration of international trade, increased tourism, and changes in methods of production in recent decades have increased the likelihood of the introduction of invasive species to U.S. agriculture. Invasive species can have adverse environmental and/or economic impacts when introduced to a region. Economic impacts include marketing, production, and trade implications. One such invasive species imposing adverse economic impacts to the Florida citrus industry is a bacterial disease known as citrus canker (Xanthomonas axanopodis pv. citri).

The forested lands in the southeastern United States account for approximately 40% of the nation’s 521 million acres of timberland, which translates to about 208.4 million acres in U.S. forestry region eight1. These timber stands primarily consist of softwoods, with various uses in wood markets including wood pellets, pulp, chip-in-saw products, and sawtimber. Long-term timber management strategies prioritizing low-grade fiber products may hinder the forest’s capacity to satisfy the lumber demands of construction markets, especially with the rise of mass timber and other solid wood product mar

ABSTRACT Laboratory-tested results in rock mechanics have played a crucial role in understanding rock behavior and failure mechanisms. This paper outlines the development of an analog rock, similar to sandstone, for an experimental study that yields a low unconfined compressive strength yet exhibits brittle failure characteristics. The F-75 Ottawa sand, Type I/II commercial grade Portland cement, air entrainment admixture, and water constitute the raw mixtures of the developed analog rock. The result is a reproducible homogeneous and isotropic rock. The effect of the air entrainment admixture

Abstract:
Abstract The enhancement of the operational flexibility of axial expanders can be obtained through the implementation of Nozzle Guide Vane (NGV). This design architecture includes moving parts typically sustained by ball joints, whose wear behavior might be important to define the maintenance interval of the expander and define its operational availability. This is especially true when considering challenging loading and temperature conditions. Usually, tribological tests are performed by pin-on disk or similar test methods. However, these techniques neglect important factors as actual sliding

In the 1960s and 1970s when the surveillance programs for currently operating commercial nuclear reactors were established state of knowledge limitations resulted in the use of Charpy-V notch (CVN) specimens rather than fracture toughness specimens. Reasonable success has since been achieved in correlating CVN and fracture toughness parameters. Such correlations provide an important part of the technical basis for both current regulations and ASME codes. These correlations imply that trends manifest in CVN data must also appear in fracture toughness data even though empirical evidence demonstr

Abstract:
It is clear that selective logging has a significant impact on the Greater Glider. Whereas the Protection Measures proposed by the Department of Agriculture and Fisheries (DAF) may produce a small decrease in the impact, DAF is proposing to continue significantly impacting this endangered species. The application of a policy to balance jobs and the environment is inappropriate for an endangered species. The overall approach of the risk assessment and DAF’s response does not appear to take account of the fact that the Greater Glider is already endangered and in serious decline. The risk assessm

Abstract:
Fruit thinning is a common and necessary practice for commercial fruit production in many deciduous tree fruit species. Fruit thinning in apple may be accomplished with a variety of chemical thinning agents, but the use of these chemicals is a subject of environmental concern. It has been shown recently that RNase enzyme, secreted from the stigma and the style, inhibits pollen germination and pollen tube elongation. In this study we have been able to show that Aspergillus niger B-1 RNase can effectively inhibit peach and apple pollen germination, and tube elongation in-vitro, as well as thin f

The history of conflict between double-crested cormorants and human interest in fisheries is long and convoluted. Overall, double-crested cormorants are not major consumers of commercial and sportfish species. However, exceptions have been recorded at specific sites with documented impacts on local fisheries. Double-crested cormorants can have a significant impact on vegetation at breeding sites through normal nesting activities. Their guano is acidic and can change soil chemistry, killing ground vegetation and irreversibly damaging nest trees. Humans should avoid direct contact with excrement
