Abstract: The most common structural material used in the construction sector is steel-reinforced concrete. However, concrete cracking and reinforcement corrosion demand constant monitoring as well as timely and costly maintenance activities. Furthermore, concrete has substantial environmental impacts, being responsible for about 7% of total CO₂ emissions worldwide. Innovative materials in construction engineering have been studied with the goal of improving the sector’s environmental performance, mostly by reducing cement content in concrete. In this context, assessing the environmental profile of such innovations is essential to avoid shifting environmental burdens elsewhere. This study evaluates the climate change impact of a novel reinforced concrete that incorporates calcined blue clay as a supplementary cementitious material and Aluminium (Al) as reinforcement. Using a cradle-to-gate Life Cycle Assessment (LCA), the climate change impact of this innovative material is compared with that of conventional steel-reinforced concrete. The result show that the climate change impact of the innovative concrete is 46% less than that of the incumbent solution. Acknowledging the early development stage of the new concrete and the limitation regarding data robustness, this work contributes to the problem-solution space and provides direction to further explore possibilities for fully unlocking the new material’s potential, so it can outperform the incumbent one in terms of greenhouse gas emissions in the future.

Abstract: Background: The appearance of Noise Artifacts is admittedly very disturbing the quality of MRI diagnostic images. The application of BLADE and STIR sequences based on artificial intelligence technology has described in reference that it is able to suppress moving signals from the vascular and signals from fat tissue. However, the long consumption of scanning time is one of the drawbacks that arise, and subsequently affect the presence of noise in the image. The use of another technique, namely kallman filter with the Matlab (Matrix Laboratory) program, which is applied as part of post-scanning image processing will help reduce image noise values ​​that arise due to the problem of long scanning time consumption in both sequences. The aim of this literature review is to determine the potential of the filter kalman for the reduction of artifacts on MRI examinations. Methods: The search was conducted using google scholar, WILEY, IEE Explore, SPRINGER, Scopus and PERPUSNAS in English with the article period 2004-2020 using the keywords MRI artifacts, reducing artifacts and the Kalman filter algorithm. Result: The results of a review of 4 articles of kalman filter intervention on MRI Brain, MRI Abdomen and MR Cardiac showed that kalman filter was good enough in reducing artifacts and increasing anatomical information. Conclusion: Kalman filter has the potential to reduce artifacts, improve image quality and clarify anatomical images on MRI examinations.

Abstract: The lead-free wood leafhopper is the iconic traditional ceramic art of the Jizhou kiln in the Song Dynasty of China. The traditional lead-free wood leafhopper is usually made of black glaze. The glaze is placed on the mulberry leaf and fired at a high temperature of about 1230 °C-1260 °C. And the veins are clear. Jizhou kiln was founded in the late Tang Dynasty. It flourished in the Five Dynasties and Northern Song Dynasty. It was the most prosperous in the Southern Song Dynasty. It began to decline in the late Yuan Dynasty and then stopped for more than 700 years. However, its unique artistic value has gradually be attracted the attention by the world. And it recovered in 1985 at last after unremitting efforts. The re-burning of the lead-free wood leafhopper has successfully opened the ceramic market of the lead-free wood leafhopper and made it occupy a certain position in the ceramic market. The price of lead-free wood leafhopper has remained high, and therefore ceramic producers are waiting for opportunities to produce on a large scale in order to achieve huge economic benefits. However, due to the great difficulty in the firing process of the lead-free wood leafhopper, the market has a phenomenon of low yield, high price, low consumer desire, and the use of chemical materials to fire products. The subject analyzed and solved these phenomena through a large number of experiments. Lead-free in this subject is a relatively broad definition, especially referring to the new type of lead-free wood leafhopper without contain heavy metals.

Abstract: It is well known that nanoparticles affect the interaction between lubricants and surfaces with various chemical compositions and different chemical and physical properties. In recent years, nanoparticles have started to play more important roles as lubricant additives for their potential in wear, friction and emission reduction and improving lubrication and fuel economy. Although nanolubricants are frequently used for friction tests, little is known about stability and degree of dispersion of these nanoparticles in viscous liquids. Most of them are unstable, agglomerate or aggregate which sediment over time. Boric acid (H₃BO₃) has always been a very important material due to its broad range of applications such as in medicine, cosmetics, automotive industry, metallurgy and also for miscellaneous purposes in other areas. Literature survey showed that friction between automobile engine parts could be greatly reduced using microscopic particles of boric acid.This study involves the new invention of successful suspension of nano boric acid (BA) additive added into 5W-40 fully synthetic commercial lubricating oil. This invention is confidential and realized by Murat ÖZAYMAN from Tribor ARGE Co. in Teknopark of YILDIZ Technical University in Istanbul-TURKEY. The particle size of BA is determined with (Transmission Electron Microscopy) (TEM). Backscattering and transmittance profiles proved that nano boric acid (BA) particles were in suspension in commercial engine oil. Suspended BA in engine oil is applied between piston ring and cylinder liner system in order to investigate their effect on friction and wear under boundary lubricated conditions. Simulation and measurement of friction and wear were conducted using a reciprocating tribometer. Surface analysis were performed using 3D digital optical microscope, Field Emission Scanning Electron Microscope (FESEM)/X-Ray, X-ray photoelectron spectroscopy (XPS) and Atomic Force Microscopy (AFM). Boron (B) from BA is well detected, mixed with other elements of additives and protected the surface under boundary lubrication conditions. The results indicate that BA can considerably improve the tribological performance of a piston ring and cylinder liner system under lubricated conditions. It has found that the friction coefficient is reduced with nano boric acid (BA) suspended engine oil and protected the surface mostly on cylinder liner mixing with other additives.
