mix cropping of alfalfa (medicago sativa) and annual ryegrass (lolium rigidum) may improve forage production in the rangeland and field conditions, especially in spring after the establishment year. in this study, the effects of different sowing rates of alfalfa and annual ryegrass seeds in the replacement and additive series of mix cropping were evaluated on forage yield in first year after th...

introduction: quality of services extremely depends on how personnel have contact and interaction with the clients. moreover, the personnel’s attitudes and their behaviors with the clients significantly affect clients’ perception of quality of services and consequently influence their satisfaction as well as their absorption to the services of an institution. this study intends to investigate t...

the strength of concrete is a function of the proportions of the constituent materials, namely, cement, water, fine and coarse aggregates. the conventional methods used to determine the mix proportions that will yield the desired strength, are laborious, time consuming and expensive. in this paper, a mathematical method based on modified regression theory is formulated for the prediction of con...

Earth building materials offer architects, engineers and clients a low carbon walling solution for rise properties (under 3 storeys). Unfortunately, the mixture of sub-soil fibre known as Cob does not currently comply with thermal aspects many regulations across world. This paper designs optimises low-density cob mix intended to maintain material’s credentials whilst conforming regulations. Sam...

Incorporating Graphene Oxide (GO) in concrete composite has been a good alternative to Pristine due its hydrophilic nature and ability readily disperse water the consequent cementitious mix. The addition of GO mix found enhance mechanical properties. This paper aims assess abrasion resistance incorporated for application road pavement design. Experiments strength terms compression, workability ...
