چکیده
The most used bricks in house building NDjamena, city of Chad which is situated semi dry arid area with 600 millimeters pluviometry per year and 50 °C as highest temperature, are raw clay bricks, terracotta or ciment block. have strong sensibility water weak resistance to compression. cement block high thermal conductivity contrary the adobe their manufacturingcontribute destroy environment. aim this paper search Stabilised Earth Block (SEB) whichare made clay, sand few percent respond climatic, environmental economic constraints. Therefore, some built mixing differentspercents (M1 : 40% 60% M2 50% M3 M4 70% 30% M5 sand, slime M6 40 % 20% clay) for obtaining physical stabilizationand adding 8%, 10% 15% cementin each type brick chemical stabilization.

Pulmonary tuberculosis diagnostic delays in Chad: a multicenter, hospital-based survey in Ndjamena and Moundou
BACKGROUND Tuberculosis remains one of the leading causes of morbidity and mortality in low-resource countries. One contagious patient can infect 10 to 20 contacts in these settings. Delays in diagnosing TB therefore contribute to the spread of the disease and sustain the epidemic. OBJECTIVES The aim of this study was to assess delays in diagnosing tuberculosis and the factors associated with...
متن کاملModification of Yellow River Sediment Based Stabilized Earth Bricks
This paper presents an experimental study on the microstructure and performance of stabilized earth bricks prepared from the Yellow River sediment. The sediment is modified by inorganic cementitious material, polymer bonding agent, and jute fibre. The results show that the sediment is preliminarily consolidated when the mixture ratio of activated sediment/cementitious binder/sand is 65/25/10. C...
متن کاملBuilding Bricks with Bricks, with Mathematica
In this work we solve a special case of the problem of building an n-dimensional parallelepiped using a given set of n-dimensional parallelepipeds. Consider the identity x = xHx 1L Hx 2L + 3 xHx 1L + x. For sufficiently large x, we associate with x3 a cube with edges of size x, with x Hx 1L Hx 2L a parallelepiped with edges x, x 1, x 2, with 3 x Hx 1L three parallelepipeds of edges x, x 1, 1, a...
