Basic Concepts In Forest Valuation And Investment Analysis: Edition 3.0, Steven H. Bullard, Thomas J. Straka

Faculty Publications

This book was originally intended to supplement lectures in forestry economics at the undergraduate level. It’s currently used for that purpose in ‘Forest Resource Economics’ courses at several universities. The book is also intended, however, to serve as a basic reference for foresters with experience in valuation and investment analysis concepts and methods. It has proven to be a valuable resource in forest valuation and investment analysis workshops for practicing foresters, landowners, and others interested in forestry investments.

Covid-19: Prevention And Control Measures In Community, Hati̇ce Rahmet Güner, İmran Hasanoğlu, Fi̇rdevs Aktaş

Turkish Journal of Medical Sciences

On January 30, 2020, the WHO declared the COVID-19 outbreak a public health emergency of international concern and, in March 2020, began to characterize it as a pandemic in order to emphasize the gravity of the situation and urge all countries to take action in detecting infection and preventing spread. Unfortunately, there is no medication that has been approved by the FDA, gone through controlled studies and demonstrated an effect on the virus for this global pandemic. Although there are cures for illnesses and developments made by leaps and bounds in our day, the strongest and most effective weapon that …

Black-Capped Chickadee Behavior-Fledging To Dispersal, Mary Van Male

Field Station Bulletins

Most studies of the family life of young birds after they leave the nest have been descriptive and anecdotal with little quantitative behavioral data, despite the many interesting problems involved in interactions of the members of a family. The objectives of this study were to determine: 1) the behavior of parents and young Black-capped Chickadees (Parus atricapillus) at the time of leaving the nest, 2) how the parents and young behave towards each other during the period when the young are dependent on their parents, 3) the factors responsible for the final disruption of the family. Since aggression was anticipated …

Sassafras Tea: Using A Traditional Method Of Preparation To Reduce The Carcinogenic Compound Safrole, Kate Cummings

All Theses

The purpose of this research is to quantify the carcinogenic compound safrole in the traditional preparation method of making sassafras tea from the root of Sassafras albidum. The traditional method investigated was typical of preparation by members of the Eastern Band of Cherokee Indians and other Appalachian peoples. Sassafras is a tree common to the eastern coast of the United States, especially in the mountainous regions. Historically and continuing until today, roots of the tree are used to prepare fragrant teas and syrups. These traditional uses can be found across cultures throughout its range. Products made from sassafras are banned …

The Study Of Tree Biomass Calculation By Comparing Partial Harvest Method With The Allometric Equations Method, Kanlayarat Jantawong, Titinan Pothong

Journal of Bioresource Management

This study aimed to investigate the effective of partial harvest method used for tree biomass estimation. Such method was analyzed for the correlation in compare with invented allometric equations. The advantages and disadvantages of those methods were discussed. The significantly difference between estimation methods were analyzed. As a result, tree biomass calculated by the Brown’s allometric equation produced highest results, followed by the partial harvest method, Tsutsumi’s, Chave’s and Pothong’s equations respectively. The selected allometric equations showed the positive correlation with partial harvest method. The highest positive correlation was found between the partial harvest method and both equation of Chave …

Forest Development In North America Following Major Disturbances

The Bark Beetles, Fuels, and Fire Bibliography

Large-scale, man-created or natural disturbances play a mjaor role in determining forest structure and species composition in many areas of North America and probably other temperate and tropical forests. Trees begin growth by a variety of mechanisms — each of which can respond to disturbances of a different severity. Studies suggest: a single group of species is not predestined to inhabit an area; forest physiognomic appearances assumed to imply all-aged succession often occur in single-age class stands; and recruitment of new stems into a forest often follows a disturbance rather than being a constant occurrence. After disturbances, forests develop through …

Epidemiology Of Covid-19, Cemal Bulut, Yasuyuki̇ Kato

Turkish Journal of Medical Sciences

It seems that coronaviruses take an important place in the 21th century history. Five of seven human coronavirus was isolated in this century. Unfortunately, last three of them entered our life with a fear of outbreak, pandemic or death. Last human coronavirus which emerged world from Wuhan China, SARS CoV-2 and its clinical expression, Coronavirus disease (COVID-19) recently taken a significant place in our daily practice. Initial reports showed that, its origin was bats. It transmitted human to human by droplet and contact routes, but some doubt about airborne, fecal or intrauterine transmission also should be removed. Its R0 value …

The Evaluation Of The Banana Tree As A Source Of Papermaking Fiber, Ivan T. Mascarenhas

Paper Engineering Senior Theses

This investigation is conducted under found broad categories - effect of various cooking methods, blending with softwood, CEHD bleaching and fiber microscopy.

It is found that the leaves are unpulpable but the stalks and stems give fibers comparable to hardwoods.

Banana pulps are uneconomical to bleach due to high Kappa numbers and acid pretreatment requirement.

The individual fibers are long, slender and stiff similar to bamboo and rice fibers. Peculiar hairlike structure are dominant.

Banana pulp can be substituted for hardwood pulp in the manufacture of bags and wrapping paper and especially advantageous for liner board due to its high …

Coronaviruses And Sars-Cov-2, Mustafa Hasöksüz, Selçuk Kiliç, Fahri̇ye Saraç

Turkish Journal of Medical Sciences

Coronaviruses (CoVs) cause a broad spectrum of diseases in domestic and wild animals, poultry, and rodents, ranging from mild to severe enteric, respiratory, and systemic disease, and also cause the common cold or pneumonia in humans. Seven coronavirus species are known to cause human infection, 4 of which, HCoV 229E, HCoV NL63, HCoV HKU1 and HCoV OC43, typically cause cold symptoms in immunocompetent individuals. The others namely SARS-CoV (severe acute respiratory syndrome coronavirus), MERS-CoV (Middle East respiratory syndrome coronavirus) were zoonotic in origin and cause severe respiratory illness and fatalities. On 31 December 2019, the existence of patients with pneumonia …
