Trichoderma And Gliocladium
This volume gives an account of the morphology and taxonomy of "Trichoderma" and "Gliocladium", before disscusing their ecology and basic biology.
Trichoderma And Gliocladium
Fungi belonging to the genera Trichoderma and Gliocladium are soil- bourne saprophytes which have been used for industrial and agricultural applications for decades. Some strains produce enzymes and antibiotics while others are useful as biological agents for the protection of plants against pathogens. This second volume of two describes the commercial uses of Trichoderma and Gliocladium, beginning with an in depth discussion of the degradation of polysaccharides and macromolecules by fungal enzymes. The application of the fungi in biocontrol for agricultural purposes is then examined. The final section of this volume deals with protein production and the utilisation of Trichoderma enzymes by various industries.
Bayesian Phylogenetics
Offering a rich diversity of models, Bayesian phylogenetics allows evolutionary biologists, systematists, ecologists, and epidemiologists to obtain answers to very detailed phylogenetic questions. Suitable for graduate-level researchers in statistics and biology, Bayesian Phylogenetics: Methods, Algorithms, and Applications presents a snapshot of current trends in Bayesian phylogenetic research. Encouraging interdisciplinary research, this book introduces state-of-the-art phylogenetics to the Bayesian statistical community and, likewise, presents state-of-the-art Bayesian statistics to the phylogenetics community. The book emphasizes model selection, reflecting recent interest in accurately estimating marginal likelihoods. It also discusses new approaches to improve mixing in Bayesian phylogenetic analyses in which the tree topology varies. In addition, the book covers divergence time estimation, biologically realistic models, and the burgeoning interface between phylogenetics and population genetics.

Writing World History in Late Ming China and the Perception of Maritime Asia
The last century of China's Ming dynasty (1368-1644) saw many troubles and challenges from abroad. Pirates raided the coast, Europeans challenged the traditional world order of the tribute system, and the everlasting threat from the northern steppe people continued to raise concerns for the state. This climate of uncertainty resulted in many Ming literati discussing foreign countries. During the last decades of the Ming, seven authors wrote monographs that can be considered a form of early Chinese "world history." The authors describe the geography, the history, and the political systems of foreign countries and regions ranging from China's close neighbors Japan and Mongolia to more distant ...
Precision Metal Additive Manufacturing
Additive manufacturing (AM) is a fast-growing sector with the ability to evoke a revolution in manufacturing due to its almost unlimited design freedom and its capability to produce personalised parts locally and with efficient material use. AM companies, however, still face technological challenges such as limited precision due to shrinkage, built-in stresses and limited process stability and robustness. Moreover, often post-processing is needed due to high roughness and remaining porosity. Qualified, trained personnel are also in short supply. In recent years, there have been dramatic improvements in AM design methods, process control, post-processing, material properties and material rang...
Breaking down silos: On post-harvest loss interventions in Tanzania
This research examines the effects of an intervention aimed at reducing Post-Harvest Losses (PHL) of maize growing farmers during their maize storage in Tanzania. Farmers were invited to attend a training on best practices in post-harvest maize management, and a randomized subset of trainees received the opportunity to buy an improved storage facility (silos) at a substantially discounted price. Data collected at 30 days and 90 days after harvest, however, do not point to significant impacts of the treatments offered to the farmers. Receiving training on best practices improved stated knowledge but training nor the opportunity to purchase an improved storage had a significant effect on maize storage and sales behavior, physical PHL during storage, or the quality of the stored maize. The research explores potential explanations and provides some policy recommendations for future learning and decision-making on how to address PHL issues in developing countries.
Secondary towns, agricultural prices, and intensification: Evidence from Ethiopia
Urbanization is happening fast in the developing world and especially so in sub-Saharan Africa where growth rates of cities are among the highest in the world. While cities and, in particular, secondary towns, where most of the urban population in sub-Saharan Africa resides, affect agricultural practices in their rural hinterlands, this relationship is not well understood. To fill this gap, we develop a conceptual model to analyze how farmers’ proximity to cities of different sizes affects agricultural prices and intensification of farming. We then test these predictions using large-scale survey data from producers of teff, a major staple crop in Ethiopia, relying on unique data on transport costs and road networks and implementing an array of econometric models. We find that agricultural price behavior and intensification is determined by proximity to a city and the type of city. While proximity to cities has a strong positive effect on agricultural output prices and on uptake of modern inputs and yields on farms, the effects on prices and intensification measures are lower for farmers in the rural hinterlands of secondary towns compared to primate cities.
Mitigation Banking
Under the Clean Water Act, development that results in the permanent destruction of wetlands must, in most cases, be mitigated by the creation of a new wetland or the restoration of a degraded one. In recent years, the concept of "mitigation banking" has emerged. Rather than require developers to create and maintain wetlands on their own on a quid pro quo basis, mitigation banking allows them to pay for wetlands that have been created and maintained properly by others to compensate for their damage. The contributors to this volume provide an overview of mitigation banking experience in the United States, examine the key issues and concerns -- from providing assurances to determining the value of credits -- and describe the practice of developing and operating a mitigation bank. Topics include: history and current experience of mitigation banking policies and concerns of local, state, and federal agencies economics of mitigation banking funding, management, and operation of banks starting a mitigation bank
