Forest harvesting and wildfire were widespread in the upper Great Lakes region of North America during the early 20th century. We examined how long this legacy of disturbance constrains forest carbon (C) storage rates by quantifying C pools and fluxes after harvest and fire in a mixed deciduous forest chronosequence in northern lower Michigan, USA. Study plots ranged in age from 6 to 68 years a...

[1] Understanding regional carbon budgets is a leading issue in carbon cycling research, but issues of measurement difficulty, scale, boundaries, and logistics compromise estimates at areas larger than stands or research plots. We studied four 15 15 km sample areas to examine land management and wildfire effects on carbon storage dynamics in the forested southeastern U.S. coastal plain region f...

The objective of this thesis was to investigate digestibility and metabolism in Icelandic horses fed forage differing in stage of maturity/harvesting date and at two feeding levels. Additional aims were to compare digestibility and metabolic plasma profile in Icelandic and Standardbred horses. Finally, one aim was to estimate the digestible energy (DE) and digestible crude protein (DCP) require...

The feedstock characteristics of the conversion platform will influence the optimal harvest and post harvest management practices for switchgrass. However, many of the harvest management practices are tied to plant phenology and will be similar across platforms. Proper harvest and storage of switchgrass will help provide a consistent and high-quality feedstock to the biorefinery. Bioenergyspeci...

Constructed wetlands (CW) offer a mechanism to meet increasingly stringent regulatory standards for wastewater treatment while minimizing energy inputs. Additionally, harvested wetland phytomass subjected to anaerobic digestion can serve as a source of biogas methane. To investigate CW wastewater polishing activities and potential energy yield we constructed a pair of secondary wastewater-fed c...

Logging harvesters represent a set of high-performance modern forestry machinery, which can finish a series of continuous operations such as felling, delimbing, peeling, bucking and so forth with human intervention. It is found by experiment that during the process of the alignment of the harvesting head to capture the trunk, the operator needs a lot of observation, judgment and repeated operat...

Fruits and vegetables are important sources of vitamins, minerals, dietary fiber, and antioxidants. The relative contribution of each commodity to human health and wellness depends upon its nutritive value and per capita consumption; the latter is greatly influenced by consumer preferences and degree of satisfaction from eating the fruit or vegetable. Flavor quality of fruits and vegetables is ...

TiO2 hierarchical nanostructures with secondary growth have been successfully synthesized on electrospun nanofibers via surfactant-free hydrothermal route. The effect of hydrothermal reaction time on the secondary nanostructures has been studied. The synthesized nanostructures comprise electrospun nanofibers which are polycrystalline with anatase phase and have single crystalline, rutile TiO2 n...

The losses in fruits and vegetables in various postharvest operations remained high in which tomato is one of the major vegetable fruit. Tomato is a sensitive vegetable whose quality is substantially reduces due to physical damage encountered by various mechanical forces in harvesting, handling and other postharvest operation. In this study an attempt was made to determine mechanical properties...

The aim of the study is to compare 3 different methods that used measure harvest losses under real field conditions for corn, soybean and cotton. A 1 m2 frame parallel planting row spacing (Method 1: M1), perpendicular 2: M2) three quarter 3: M3) were calculate losses. This M1, M2, M3 in corn with combine harvester. Then M1 M2 when harvesting cotton a picker. 5 grids established same measuring ...
