seeds deterioration is a natural phenomenon that occurs in all seeds and leading to gradual decline of seed viability during storage. however, the rate at which seeds age depends upon their physiological status, genetic constitution and storage conditions. in the present study we the examined relationship between accumulation of reducing and non-reducing of sugars, soluble protein, the activity...

Historical masonry structures made from locally available materials such as stone, brick, and mud are an integral part of our cultural identity. Moisture content is a critical environmental factor that can significantly impact the durability strength these structures. ingress in cause detrimental effects decreased strength, increased porosity, reduced bond between mortar units. Understanding th...

To better understand the effects of biological soil crusts (BSCs) on soil moisture and wind erosion and study the necessity and feasibility of disturbance of BSCs in the Mu Us sandland, the effects of four treatments, including moss-dominated crusts alone, Artemisia ordosica alone, bare sand, and Artemisia ordosica combined with moss-dominated crusts, on rainwater infiltration, soil moisture, a...

Biomass, mainly in the form of wood, is the oldest form of energy used by humans. Gasification is a process of conversion of solid carbonaceous fuel into combustible gas by partial combustion. In the present study, a model developed by us in our earlier study is used for predicting the steady-state composition and rate of reaction profiles for the reduction zone of the downdraft biomass gasifie...

UNLABELLED The public health risk and economic impact of dampness and mold exposures was assessed using current asthma as a health endpoint. Individual risk of current asthma from exposure to dampness and mold in homes from W.J. Fisk, Q. Lei-Gomez & M.J. Mendell [(2007) Indoor Air, [corrected] 17, 284-296], and [corrected] asthma risks calculated from additional studies that reported the preval...

there are different methods used for threshing of grain crops. usual threshers operate based on the impact force (in threshing unit) that may damage the grains. in another method named axial-flow, grain damage is less so these types of the harvesting machines are being used more than before. in this study one of the common rice threshers (model t30) locally made in ashtad company was modified t...

Pressure ulcers, also referred to as pressure sores, decubitus ulcers or bedsores, are defined as an area of localised damage to the skin and underlying tissue caused by pressure, shear force, friction, moisture, and/or a combination of these factors 2. They develop from continuous pressure that affects cellular metabolism and impedes or obstructs capillary blood flow to the skin and underlying...

The implementation of WMA is becoming more widespread with a growing number of contractors using various WMA technologies. Early research suggests WMA may be more susceptible to moisture damage than traditional HMA mixes. Asphalt performance tests can be a good way of measuring material responses that can be correlated with pavement performance. It is important for owner/agencies to know that t...

This paper presents the results obtained with the simulations of a sandwich rectangular plate made of carbon/epoxy composite when subjected to temperature and humidity cycles. Fickian diffusion process, moisture transport along the interfaces and damage caused by slipping and debonding between the components of the microscopic structure are considered. The application of the design methodology ...

To modify water absorption properties of bamboo fiber (BF) and high density polyethylene (HDPE) composites, heat treatment of BFs was performed prior to compounding them with HDPE to form the composites. The moisture sorption property of the composites was measured and their diffusion coefficients (Dm) were evaluated using a one-dimensional diffusion model. Moisture diffusion coefficient values...
