Wood is a biological material that, when in the tree, contains large amounts of water. As wood dries to a moisture content (MC) in equilibrium with its in-use environment, many of its properties and characteristics change. Classifying wood as either a hardwood or softwood comes down to its physical structure and makeup, and so it is overly simple to think of hardwoods as being hard and durable compared to soft and workable softwoods. The hardwood are comes from angiosperm trees that are not monocots. Trees are usually broad-leaved. Has vessel elements that transport water throughout the wood under a microscope, these elements appear as pores. While, the softwood are comes from gymnosperm trees which usually have needles and cones. Medullary rays and tracheid transport water and produce sap. When viewed under a microscope, softwoods have no visible pores because of tracheid. We choose the dried lumber as our specific material. The dried lumber has several types. There are Kiln Dried, Kiln Dried and Heat Treated, Tru-Dry, Green Heat Treated, Surface Dry and Air Dry. Most water in the cut tree must be …show more content…
This wood is dried in a Radio Frequency Vacuum (RFV) kiln. The radio frequency vacuum kilns also have a compressive loading system which applies 250,000 lbs. of pressure on the charge throughout the drying cycle. This helps maintain straightness and squareness throughout and after the process ensuring the highest quality lumber. The Tru-Dry timbers perfect for structural and architectural applications in timber frame houses, resorts, lodges and any other project that requires timbers to remain straight, stable and beautiful for years to come. While other drying methods only remove surface moisture, Tru-Dry timbers are dried to an average of 19% to their
There are two different styles of log home construction. The first is manufactured log homes also known as kit homes. The logs are mechanically shaped into uniform dimensions. Manufactured logs may also be milled round or rectangular in profile with endless variations. The second type of construction is handcrafted. The natural characteristics of the logs are preserved to show off their individuality and the joinery of the logs is done with hand held tools. There are three different styles of logs. The first is a D shape log for the exterior log look and flat indoor appearance. The second is fully rounded logs to give the full log look on both the interior and exterior. The third is a square log that gives the appearance of timber construction, being flat on all four sides, with the advantages of log building. Depending on the manufacturer and your corner type, milled logs also come with tongue and grooves on the top and bottom of the logs for a more secure fit.
Shortleaf Pine (Pinus echinata) and Pulp and Lumber Production. Introduction Shortleaf pine (Pinus echinata) is commercially one of the four most important conifers in the southeastern United States. In fact, shortleaf pine has the widest range of all southern pines, spreading from Florida to New Jersey and from North Carolina to Oklahoma. Sidney Investments, a firm based in Dallas, Texas, is considering the purchase of a 360-acre parcel of forested land located in the Quachita Mountains of eastern Oklahoma. This land has been under timber production through one rotation to this point.
When the "new" management took over Pacific Lumber the process of "selective cutting" was abandoned and "clear cutting" was adopted. Although "clear cutting" is a way to obtain so-called fast cash, it wa...
The papermaking process begins with pulp. Pulp is cellulosic fibrous material extracted from cellulosic fiber from wood. Glatfelter uses the Kraft Process to make both hardwood and softwood pulps. Hardwood pulps are taken from oaks, beeches, poplars, birches and eucalyptus tress. They have short fibre of average length of 1 millimeter. The primary purpose of hardwoods is for the paper to achieve bulkiness, smoothness and opacity. Softwood on the other hand is taken from pine and spruce with long fibre averaging 3 millimeters, it provides addition strength to paper. Both softwood and hardwood are produce independently of each other and are mixed end at desire ratio in the paper plant. The process starts from wood chips. Trees are chipped to make wood chips from half an inch to an inch long and up to two fifth inches thick. The chips are feed into a digester, which with cooking liquor would create a chemical reaction, which delignificate the wood. The cooking liquor is composed of white and black liquor. White liquor is composed of mainly sodium hy...

Many trees house other plants within their branches. Our Myrtle Oak tree has a symbiotic relationship with the Tillandsia air plant. The Tillandsia species are epiphytes or air plants because they normally grow without soil while being attached to another plant. (MacCaskey) This type of plant has no need for soil because its source of water and nutrients are absorbed through their leaves. The leaves are long and whip-like in shape with a silvery green
Woodworking has been around for millennia or more. People have used wood for building shelter, tools, and other useful things. There are many different kinds of woodworking. The most common today are marquetry and parquetry, which are both forms of veneering and caring. There are many different styles of woodworking all of which are a very impressive art form.

Trees grow into woody plants with a main trunk, many branches, and come in varieties of shapes, leaf types and reproductive organs. Tree roots can spread up to three meters in depth and width, sometimes damaging buildings or footpaths (http://en.wikipedia.org/wiki/Photosynthesis, 2010). All plants photosynthesise, allowing production of their own food, by converting carbon dioxide and water into glucose and oxygen using sunlight energy. Therefore as all organisms release carbon dioxide through respiration, only plants use it to produce oxygen, which is a circular process (http://en.wikipedia.org/wiki/Photosynthesis, 2010).
We proposed that at what rate (Early, Middle, Late) do the leaves fall on East Carolina’s Campus for the White Oak Tree? Does the rate change in the regions of California and New York? The White Oak has a broad tolerance for thermal and moisture conditions. Depending on the climate is what factors the rate of the leaves falling.
