in this study, compressed poplar wood was used to improve the strengths of wooden chairs. these chairs were compared to chairs made from uncompressed poplar wood. wooden chairs were assembled with two types of traditional joints including mortise and tenon and wooden pins joints. the ultimate force was applied from the front to the back of the seat, were recorded according to american library a...
attempts have been made to study the thermodynamic behavior of 1,3 butadiene purification columns with the aim of retrofitting those columns to more energy efficient separation schemes. 1,3 butadiene is purified in two columns in series through being separated from methyl acetylene and 1,2 butadiene in the first and second column respectively. comparisons have been made among different therm...
In this study, it was aimed to determine the coefficient of acceptability for furniture joints on chair frames. doing so, three configurations made soft maple and yellow poplar were defined. Chairs subjected a front-to-back cyclic load test until non-recoverable failure occurred. Ultimate loads each frame used moment capacity critical joints. Likewise, according American Library Association, ac...
This study evaluates the edgewise bending moment capacity of the four most frequently used middle joints in the upholstered furniture frames. The research included the following joints: Mortise and Tenon, double Dowel, Corner Blocks and double Gusset Plates, designed in the form of middle joints and made of beech and poplar solid wood. The test results indicated that regarding the edgewise bend...
in the name of allah , the compassionate the merciful abstract shath ( blasphemic utterace made during spiritual ) is a complicated concept that deserves reflection in gnosticism and sufism ( mysticism ) and estem and westem scholars have alwaya paid attention to it. although principal essence of gnostic belief is the holy divine law ,gnosticism has pure and unique thoughts . by glancing at t...
wood farming and especially poplar plantation is a key answer to the increasing demand of raw materials in wood and cellulosic industries. according to the diversity of wood applications, taking into account the wood quality and grading by wood farmers/buyers as well as its quantity can lead to an optimal management of production and consumption. in this regard, it is necessary to introduce and...
light weight wood base sandwich panels have some special properties and their most important properties is high mechanical strength with its light weight. these panels can replace instead of traditional structural systems in iran. the purpose of this paper is investigating the mechanical properties of light weight wood base sandwich panels that have made from sunflower stalk wastes and particle...
chapter two presents three m-admissible function algebras ab, bd, and sl, to construct the universal abelian, band, and semilattice compactifications, respectively. the main results are (11.3), (12.3), and (12.4). some inclusion relationships between these function algebras and the other well-known ones, presented in section 8, are made via the devico of compactifications. chpter three is about...
Tests were conducted to compare the performance characteristics of school chairs constructed with pinned but unglued round mortise and tenon joints with those of chairs with glued but unpinned joints. Chairs with 0.125-inch cross pins in 0.723-inch diameter tenons developed over 90 percent of the strength of the chairs with glued tenons, whereas chairs with 0.313-inch diameter pins developed on...
