Residential buildings help to facilitate the occupants against solar radiation and adverse weather conditions. However, growing increase in climate change our environment has resulted different side effects on human’s health mostly northern region of Nigeria other parts world where high from sun are experience. This key interests this research possible thermal insulation materials that can resi...

Abstract The performance of the Photovoltaic (PV) module as a building material is analyzed by predicting hourly variation in room temperature compared to base case (conventional material). A computer simulation model Fourier admittance method used for analysis. average fluctuation PV roof and wall 6.58°C 2.91°C respectively. total daily energy generation from found range 6.7 kWh 11.86 kWh, its...

In the present investigation vessels of 16 species of family Asclepiadaceae have been studied. Through a lot of variation exists in the size and shape of vessels, number of perforation plates and intravascular thickening of walls in the taxa, the vessels in asclepiadaceae are found highly specified.

When asbestos containing materials (ACM) must be removed from the building before demolition, additional greenhouse gas (GHG) emissions are generated. However, precedent studies have not considered the removal of ACM from the building. The present study aimed to develop a model for estimating GHG emissions created by the ACM removal processes, specifically the removal of asbestos cement slates ...

Glucose, lactose, and saccharose were used as precursors to prepare chars at 400 °C then activated at 800 °C or 1000 °C in closed vessels with controlled amounts of oxygen penetrating through nanopores in the vessel walls. There are correlations between the porosity, amounts of residual O- and H-containing functionalities, and electroconductivity of amorphous carbons studied. The pore size dist...

The infrared spectra of water confined in well controlled pore glasses were recorded as a function of the pore size ranging from 8 to 320 nm and in the 30-4000 cm(-1) spectral range using the ATR technique. The experiments prove that even in the large pores, the water network is significantly perturbed. The energy of the connectivity (or hindered translation) band (around 150 cm(-1)) is found t...
