Wooden furniture production consumes a lot of forest resource and other resources, so it is important to estimate its environmental effect. In this research, we collected data in sofa factory China appraised environment impacts by the ecological footprint (EF) methodology. The results showed that total EF was 2 316.25 gha/year (gha: global hectare). average 0.18 gha/year. For factory, main cont...

This study was conducted to characterize metabolic features of the breast muscle (pectoralis major) in chickens affected with the Wooden Breast myopathy. Live birds from two purebred chicken lines and one crossbred commercial broiler population were clinically examined by manual palpation of the breast muscle (pectoralis major) at 47-48 days of age. Metabolite abundance was determined by gas ch...

Elastic waves in materials with cylindrical orthotropy are considered, this being a plausible model for a wooden pole. For time-harmonic motions, the problem is reduced to some coupled ordinary di erential equations. Previously, these have been solved using the method of Frobenius (power-series expansions). Here, Neumann series (expansions in Bessel functions of various orders) are used, motiva...

Sweden is forecasted to grow its population with 1.1 million people over the next eight-year period, increasing the demand on the construction phase of housing units throughout Sweden. However, at present, 240 of Sweden's 290 municipalities show an existing deficit of available housing units in their regions, resulting in inherent difficulties fulfilling this demand utilizing the current produc...

Progressive collapse is defined as the spread of an initial damage from one member to another, leading to extensive partial or total collapse of the structure. In this research, the potential of progressive collapse due to a sudden removal of vertical load-bearing elements in reinforced concrete buildings structures with different floor plans such as geometrical regular and irregular floor plan...

presence of arsenic, a heavy metal, in soil and water resources originating from geological formations of qorveh plain, which is considered as the main agricultural zone of kurdistan province in western iran, has put the agricultural products of this region at risk of pollution. since arsenate, as the most abundance form of arsenic in soil environment, competes against phosphate anion; applicat...

the main cause of structural damage in buildings subjected to seismic actions is lateral drift. in almost all reinforced concrete (rc) structures, whether designed with walls or frames, it is likely to be the code drift limits that control the design drift. the design drift limits and their contribution to damage may be represented indirectly through the material strain limits. the aim of this ...

Latin hypercube designs (LHDs), widely used for computer experiments, are a very large class of designs with desirable properties. Recently, a number of methods have been proposed to construct orthogonal LHDs. In this paper, we introduce an approach to constructing 2-order orthogonal designs. The methods are simple and easy to implement. Using orthogonal designs, we propose some methods for con...
