Corrugated bamboo roofing sheets (1)

What are corrugated bamboo roofing sheets? Corrugated bamboo roofing sheets (CBRS) are an excellent alternative to corrugated asbestos, iron, plastic or zinc roofing sheets. They are produced from natural materials and are attractive, durable and resilient to adverse weather conditions and pest attack. They can be produced in a range of standard sizes and can be used to roof dwellings, stores, animal pens and other buildings. How are they produced? CBRS are produced by pressing firmly together woven bamboo mats that have been impregnated with an adhesive resin. The corrugations are formed by pressing them between corrugated pressing plates in the pressing machine. What is the market for corrugated bamboo roofing sheets? The market for CBRS is somewhat variable in different regions of the world but depends to a large extent on successful marketing strategies. CBRS is popular in rural areas where the low prices are attractive. The potential to increase the use of CBRS in more affluent areas is enormous, and there is considerable export potential in the markets of the more affluent countries where their eco-friendly nature could be a major selling point. What is the role of a corrugated bamboo roofing sheets unit in rural development? The unit itself will provide employment to a range of people and there will be extra employment generation in its forward and backward linkages, such as cultivation and harvesting of bamboos, primary processing, mat weaving, marketing and retailing. A unit producing 500, 000 m2 of sheets per year will require a total workforce of over 200 people. The need for a sustainable supply of raw materials will encourage the proper management of bamboo stands, and the establishment of new plantations, with their associated environmental benefits. How do I establish a corrugated bamboo roofing sheets-making enterprise? A corrugated bamboo roofing sheets manufacturing unit requires a regular supply of bamboo mats, electricity, labour and access to markets. An enterprise with a capacity of 500, 000 m2 per year can be established for approximately USD $26, 000 in Vietnam but costs will vary in other countries.Corrugated bamboo roofing sheet

Regularized estimation for highly multivariate log Gaussian Cox processes

Statistical inference for highly multivariate point pattern data is challenging due to complex models with large numbers of parameters. In this paper, we develop numerically stable and efficient parameter estimation and model selection algorithms for a class of multivariate log Gaussian Cox processes. The methodology is applied to a highly multivariate point pattern data set from tropical rain forest ecology

Studies in Forest Ecology

Casual observations made during botanical excursions to various parts of the state during the past twelve years have revealed a very scattered and unusual distribution in Indiana of the hemlock, Tsuga canadensis. As stated by Deam (4), this species is usually to be found in Indiana on north-or northwest-facing slopes. It is most commonly found on the steep slopes, canyon walls and rims of deep ravines, but may also be found in pure stands in some places such as at Turkey Run, in Parke county, where it is associated with beech and maple on plateau tops above canyon walls, and at Pine Hills, in Montgomery county, where it is associated with beech (Fagus grandifolia), maple (Acer saccharum and A. nigrum) and white pine (Pinus strobus)

Corrugated bamboo roofing sheets (2)

Corrugated bamboo roofing sheets are plywood-like roofing materials made from layers of woven bamboo mats that have been coated with glue and then pressed firmly together. The corrugations are formed by pressing the mats between corrugated pressing plates. Corrugated bamboo roofing sheets are an excellent alternative to asbestos, iron, zinc or plastic roofing sheets. They are attractive, durable and highly resistant to adverse weather conditions and pest attacks. Corrugated bamboo roofing sheets can be produced in a variety of sizes and used to roof a wide range of buildings.Corrugated bamboo roofing sheet
