Domínguez-Rodrigo et al. (1) critiqued our paper (2), which provided the earliest evidence for stone tool use and animal tissue consumption as evidenced by bones bearing tool-induced marks found at DIK-55 (Dikika, Ethiopia) and dated to 3.39 Ma. Applying a configurational approach, they questioned the bones' context and without examining or conducting new analysis on the original fossils, argue...

The misuse of waste material has developed into another draw because the significance consciousness and unpleasant feelings. A by-product refinement silicon ferrosilicon is silica fume (SF). design production reinforced concrete seen remarkable success with fume. One most crucial elements commercial viability modern work been short-term usage Silica Rage (SR), as well manufacturing SF-regulated...

A new Dipterus−like lungfish, Harajicadipterus youngi, is described from the Givetian (Middle Devonian) Harajica Sand− stone Member of central Australia. The material is comprised of five specimens representing the skull roof, orbital bones, tooth plates, operculo−gular bones, a partial pectoral girdle, centra and scales. Harajicadipterus can be distinguished from other dipnoans by its long pos...

LIGHTWEIGHT CONCRETE May consist of lightweight aggregates are used in ordinary concrete of coarse aggregate and sand, clay, foamed slag, clinker, crushed stone, aggregates of organic and inorganic. It used in different common shapes such as light weight aggregate concrete [1], concrete without fine [2] or concrete with bubble [3]. It is replaced by normal concrete in several applications becau...

In this paper, the particle shape factor of stone in soil-rock mixture was used as specific research object geogrid pull-out test, combining random generation method and evaluation criteria rock blocks mixture, a feasible for classifying stones according to their factors is presented. By comparing mechanical behavior composed with different material tests under working conditions, we studied it...
