Cracking is one of the major factors that reduces the durability and service life of concrete structures. In recent years, bacterial self‑healing concrete has emerged as a sustainable solution to enhance crack healing and improve structural performance. This study investigates the mechanical properties and crack healing behavior of bacterial concrete incorporating Bacillus megaterium. Experimental investigations were carried o...

As anthropogenic disturbance restructures ecological communities worldwide, ecologists have developed and tested hypotheses about which species “win” and “lose” in the face of human impacts. One heavily invoked paradigm is that of the human shield, which posits that predators avoid areas of human disturbance due to perceived risk from humans, and prey therefore seek refuge in these areas of perceived safety. Since its introduc...

Concrete pavements are renowned for their ability to handle heavier loads and lower life cycle costs than flexible pavements. Fibers into concrete further enhance its durability by reducing maintenance and rehabilitation costs. This study investigates the fatigue performance of pavement quality concrete (PQC) M40-grade reinforced with polyolefin fibers, focusing on structured fibers (SF) and twisted fibers (TF). Polyolefin fib...

Aim We test the hypothesis that wind dispersal is more common among emergent tree species given that being tall increases the likelihood of effective seed dispersal. Location Americas, Africa and the Asia‐Pacific. Time period 1970–2020. Major taxa studied Gymnosperms and Angiosperms. Methods We used a dataset consisting of tree inventories from 2821 plots across three biogeographic regions (Americas, Africa and Asia‐Pacific),...

The detection of uranium in drinking water has ignited concerns among the public, regulators, and policymakers, particularly as around 1% of the 55,554 water samples in India have shown uranium levels surpassing the 60 µg/l guideline established by the Atomic Energy Regulatory Board (AERB) based on radiological toxicity. Further, the Bureau of Indian Standard (BIS), has given a limit of 30 µg/l, which is derived from World Hea...

Concrete has become a versatile material by adapting itself to user needs, from pavers to skyscrapers. Escalated demand for concrete is the prime reason for the exploitation of resources and increased carbon emissions. This research focuses on reducing the environmental impact of cement manufacturing by partly replacing cement with 40% ground granulated blast furnace slag (GGBS) and 20% fly ash (FA). Waste management is also u...
