the entomopathogenic fungus metarhizium anisopliae (metschnikoff) sorokin, causal agent of green muscardine of insects, is an important fungus in biological control of pests. no reports exist on the impact of this fungus on microcerotermes diversus silvestri (iso.: termitidae) in the world. the present research evaluated efficacy of strain demi001, from saravan, iran, against m. diversus. the t...
the current research was planned to investigate the effect of maleic anhydride (man) and glycidyl methacrylate (gma) treatments on morphological and physical properties of the hornbeam wood-styrene composite. test samples were divided according to astm d4446-05 to control and treated with man, st, man/st and man /st/gma. treatment was performed by vacuum- pressure method using a experimental cy...
background: asthma is a chronic multifactorial disease with a high prevalence. among asthma risk factors, the effect of baking in wood tenor ovens (traditional form of baking) on bronchial asthma is still debated. the aim of this study was to determine the association between baking in wood tenor ovens and incidence and control of bronchial asthma. materials and methods: this descriptive study ...
the creep/recovery behavior of wood flour-polypropylene was compared with medium density fiberboard (mdf) and particleboard. for this purpose, wood flour-polypropylene composites (with and without compatibilizer)were manufactured by using a laboratory twin-screw extruder. the mdf and particleboard panels were obtained from local producers. short term flexural creep tests at 30% of ultimate bend...
Economists believe that the development of the industry sector is for the benefit of other sectors of the economy. In 23 groups of industrial activity in classification ISIC, the production and export of wood industries have received less attention in developing countries. exports of wood products have a major impact on the GDP and provide employment and sustainable development of natural resou...
The use of organic materials is increasing in agriculture and industrial products due to their less side effects than chemical materials. In order to study the effect of pine wood vinegar (Pyroligneous acid) on growth and physiological traits of basil, two experiments were designed and conducted in 2014, based on a completely randomized design with 6 treatments (0, 1250, 2000, 2500, 3333 and 50...
The objective of the article is to investigate the variability in growth and wood properties of the willow clones. The growth and wood traits of four year old 21 clones willow clones were investigated. Analysis of variance showed that willow clones differed significantly for all the studied growth and wood traits. Among the growth parameters the maximum heritability value was shown by height wh...
In Thailand, RSS chamber of community-level rubber cooperatives can be classified into two models: old and new model, named after the years of their establishment. Hot gas as a heat supply from Para-rubber (PR) wood (Hevea brasiliensis) combustion is used for removing moisture from the natural rubber (NR) sheets. Smoke and soot particles from PR wood burning has effected to the quality of the N...
