The acidity of spent lubricant was treated using sodium hydroxide solution. The effect of three variables on the treatment have been studied . These are mixing time rangingfrom 5-35 minutes, NaOH to lubricant weight ratio ranging from 0.25-1.25 and weight percentage of NaOH ranging from 2-6 % . The experimental design of Box-Wilson method is adopted to find a useful relationship between the three controllable variables and the lowering in the acidity of the spent lubricant. Then the effective variables and interactions are identified using the statistical analysis(F-test) of three variab

Abstract:

The roundness quality of small meatballs, called Bakso Unyil, produced by PT X has been considered non-uniform and in-competitive. Hence, roundness quality improvement has been becoming one of the priorities for increasing consumer acceptance. This research aims to identify the causes of the poor quality of Unyil Meatballs roundness and find a solution. The improvement methods were: identification of the causes of low quality of roundness (Plan), improvement trials based on alternative solution (Do), and implementation of corrective actions (Action).

Abstract:

Improvement of the mixing quality of low Reynolds number flows in micro-dimensional devices is essential. This paper investigates the optimization of the effective parameters and their effects on the mixing quality in a two-dimensional active micromixer. The micromixer mixes fluids with different concentrations entering into a microchannel from different inlets by means of four microelectrodes placed on the walls of a mixing chamber. A time-dependent electric field is applied, and the resulting electroosmotic force perturbs the parallel streamlines in the otherwise highly ordered laminar flow.

This study introduces soil squeezing technology (SST) as an innovative approach to soil improvement that addresses the limitations of conventional methods in urban geotechnical projects. Unlike traditional in situ mixing, SST uses displacement, compaction, and controlled solidification to effectively increase soil cohesion and strength while reducing voids. By minimizing reliance on large mixing plants and bulky machinery, SST offers significant advantages in confined urban spaces, providing accessibility and operational efficiency. This paper describes the mechanism of SST, field application

Abstract:

The article addresses the problem of the quality improvement in respect of the concrete mix preparation in the context of intensive mechanization and automation. The co-authors suggest new processes to improve the performance reliability of the operating element of a mixer through the improvement of the wear resistance of its blades. The build-up of the wear-proof layer has boosted the durability of the components of the operating element of a mixer. The logical relationship between the mechanized and automated operations enabled the co-authors to adjust the optimal composition of the concrete

Abstract This study aims to systematically analyze the effects of various operational parameters on the continuous mixing process of concrete using the Discrete Element Method (DEM) combined with a wet mixing model, with the objective of optimizing mixing uniformity and material flow to improve concrete mixing quality and efficiency in practical engineering applications. The results indicate that an appropriate water addition rate (e.g., 10 m/s) and a moderate moisture content (e.g., 2:9) can significantly enhance the uniformity of concrete mixing. Additionally, a moderate rotational speed (e.

Abstract:

Concrete with crushed concrete aggregates (CCA) shows lesser compressive strength than reference concrete with natural aggregates. The goal of this study is to improve the strength of structural concrete with 53% and 100% CCA replacements without increasing the cement content. Thus, improvements in CCA quality are induced by combining mechanical and pre-soaking pre-processing techniques. Mechanical pre-processing by rotating drum is separately pursued on fine and coarse CCA for 10 and 15 min respectively. Results show, adhered mortar content and CCA water absorption reduces as pre-processing d

In recent years, flexible perovskite solar cells have drawn tremendous attention in the field of wearable devices, and optimization of perovskite composition plays an important role in improving film quality and photophysical properties. At present, some researchers have only studied A-site organic cations mixing or X-site halide anions mixing in the ABX3 structure of perovskite, but there are few reports on co-mixing of A-site and X-site ions in flexible perovskite solar cells. In this paper, we mainly try to study the effects of different concentrations of mixed formamidine methylamine halid

Abstract The method of seam welds quality control using X-ray is considered. The X-ray methods of control are based on the capability of gamma radiation to penetrate through a metal including welded areas. Regions having defects - pores, faulty welds, cracks, scale inclusions - look darker on images. Appearance, linear dimensions and depths of the defects usually are determined by a visual examination comparing the X-ray image with standard defects images. It is known that a human eye can distinguish not more than 12-15 shades on a black and white image but more than a hundred on a colored ima
