One of the new methods of anchoring steel structures is the use of large-scale buckling-restrained braces (BRBs) on the lateral system of this type of structure. This study investigates the behavior of BRBs and compares them with buckling braces. In this study, a two-dimensional frame with four stories and four spans was taken and analyzed in eight...

Improving the quality of iron ore sintering and adding specific components has positive effects on blast furnace productivity. Optimizing basicity in the blast furnace charge is one way to improve all indices of production processes. Adjusting basicity aims to achieve the formation of new phase compounds that are favourable for the metallurgical an...

Plastic has become indispensable since its introduction in the late 1800s, valued for its flexibility, durability, and affordability. Global plastic production has grown exponentially, reaching 400.3 million metric tons in 2022, despite a temporary decline in early 2020 due to the Covid-19 pandemic. However, only 9% of all plastics ever produced ha...

This study evaluates three hybrid electrocoagulation (EC) processes with aluminium electrodes:EC-zeolite process (EC+Z), EC-zeolite-ultrasound-assisted process (EC+Z+US), and EC-zeolitemagnet-assisted process (EC+Z+MAG) for compost wastewater treatment with a large content oforganic matter. The focus was on evaluating the effects of these processes...

Phytoremediation with wild plant species could be an environmentally friendly and economicalsolution. Selected wild plants like mint, oregano, chamomile, nettle, and St. John’s wort, from ruralareas in Bosnia and Herzegovina, were collected, lyophilized, and acid-digested for heavy metalsanalysis. Nickel (Ni), copper (Cu), chromium (Cr), cadm...

This paper describes the difference in the creep rate of pre-strained and no pre-strained samples of superalloy N07080. The primary strengthening mechanism of this superalloy is based on the precipitation of fine and coherent particles of the intermetallic γ' phase Ni3(Al,Ti) that ensure good creep resistance. In the case of additional streng...

The production of concrete structural steel using controlled cooling with Tempcore technology enables the production of high-strength steel with improved adhesion to concrete while ensuring homogeneous properties for the construction of buildings, bridges, highways, and other construction facilities in any geographical environment. Concrete reinfor...

The assessment of workplace hazards involves recognizing the likelihood of occurrence and the severity of potential injuries or occupational diseases to employees. The risk assessment is performed by a team of experts from various scientific and professional fields to objectively evaluate the attributive and/or numerically expressed level of risk, ...

In this article we present the original Georgi-Glashow  model with gauge and fermion sector derivation in order to show grand unified theory (GUT) through this model, but also to correlate  and Standard Model (SM). One of the correlations reside in neutrino mass sector where both and Standard Model (SM) see neutrinos as massless particles...
