This paper details the effect of fiber reinforcement on mechanical characteristics by-products based one-part alkali activated material (AAM). Two different binder matrices were considered in this study, such as, plain slag, and ternary blended to understand their efficiency reinforced system. These with 1% v/v three fibers (steel, glass basalt) improve flexural performance high strength mortar...

Sympatric speciation has been controversial since it was first proposed as a mode of speciation. Subterranean blind mole rats (Spalacidae) are considered to speciate allopatrically or peripatrically. Here, we report a possible incipient sympatric adaptive ecological speciation in Spalax galili (2n = 52). The study microsite (0.04 km(2)) is sharply subdivided geologically, edaphically, and ecolo...

The use of industrial by-products, e.g., fly ash, slag, as complete replacement Portland cement to make alkali-activated concrete (AAC) has become a hot topic due the contribution sustainability in construction industry. AAC comparable compressive strength compared ordinary (OPC) and many advantages, such excellent durability corrosion resistance. However, similar OPC, AACmaterial still certain...

Today, 31 countries operate ∼ 450 nuclear power reactors supplying electric power to ∼ 1 billion people,∼ 15% of the world population. Nuclear reactors generate∼ 17% of global electric power needs and a number of industrialized countries depend on nuclear power for at least half of their electricity. In addition, ∼ 30 nuclear power reactors are presently under construction worldwide (Macfarlane...

[1] Lonar crater is a simple, bowl-shaped, near-circular impact crater in the 65 Myr old Deccan Volcanic Province in India. As Lonar crater is a rare terrestrial crater formed entirely in basalt, it provides an excellent opportunity to study the impact deformation in target basalt, which is common on the surfaces of other terrestrial planets and their satellites. The present study aims at docum...

Introduction: In a continuing study of mare basalts and factors affecting their composition, volume, and eruption duration (e.g., incorporation of K-U-Th), we examine the compositions of mare basalts and nonmare units on the floor of Australe Basin. This pre-Nectarian basin is located on the southeastern limb of the Moon (52°S, 95°E) [1], far removed from Th-enriched proximal and possible antip...

Recently, geopolymer binders have been considered because of low cost, simple processes for synthesis and many raw materials in nature. Geopolymer with brittle nature does not have high strength and cannot be used alone for structural materials. Therefore, to use in different structures, the composite which is reinforced with fibers such as carbon, glass, basalt, etchasbeen used. In this resear...

The Rover Environmental Monitoring Station (REMS) is one of NASA/MSL's instruments, which has been designed for measuring ambient pressure, humidity, wind speed and direction, UV radiation, and air and ground temperature (GT). The GT-sensor is dedicated to measure the real temperature of the Martian surface, integrating the IR energy coming from the ground. The existing IR spectral data of Mart...

Hydrogen (H2) is produced in geological settings by dissociation of water due to radiation from radioactive decay of naturally occurring uranium ((238)U, (235)U), thorium ((232)Th) and potassium ((40)K). To quantify the potential significance of radiolytic H2 as an electron donor for microbes within the South Pacific subseafloor basaltic aquifer, we use radionuclide concentrations of 43 basalt ...
