The study sought to explore the impact of the approved approach of application of Lean and Six Sigma, which focuses on improving quality and reducing lead-time, and removing waste in the supply chain. As this integration of both applications is suitable for small and medium-sized companies (SMEs), the manager of company X wishes to solve its problems in lead time and transportation costs. The paper used the application of Lean and Six Sigma within the DMAIC stages.(define, measure, analyse,...

Understanding the PVT parameters is essential for various petroleum calculations, including the assessment of hydrocarbon flow characteristics, forecasting future performance, designing production facilities, and strategizing enhanced oil recovery methods. Ideally, the PVT properties of hydrocarbons are derived from laboratory analyses conducted on either bottom-hole samples or recombined surface samples. However, laboratory data may not always be accessible due to economic or technical...
The burgeoning field of genomics has reinvigorated interest in multiple-testing methods as it introduces new methodological and computational challenges. Whole genome microarray studies (e.g., differential expression, differential methylation, ChIP-chip) offer the possibility to test millions of traits in one genome. This article discusses the preterment of Adjusted likelihood approach and Average estimate approach (see Ewhida, Alammari and Ihwil, 2022; Jiang and Doerge, 2008) for estimating...
The notion of β -open set and δ δ -open set were introduced by many topologists and several research papers with interesting results in different respects came to existence. Also, the notion of b − δ -open set was introduced by Almalty (2011). The aim of this work is focused on generalization of functions in topological space and new classes of functions called weakly b − δ -open function and weakly b − δ -closed functions via b...

Hydrodynamic pressure technique is a relatively new and innovative technique for rheological studies of viscous Newtonian fluids. These principles extensively used for the last twenty years for drawing and coating of strips and wires. The Rheometric Device consists of a rotating inner cylinder (rod) in a fixed hollow outer cylinder. The complex geometry gap between the two cylinders filled with a viscous non-Newtonian fluid. When the rod rotates inside, while the hollow cylinder filled with...
Exposure to high-dose ionizing radiation is known as a human carcinogen factor, but our information about the effects of low-dose ionizing radiation such as occupational exposures is limited. The main concern of scientific community is biological consequences due to low-dose radiations. This study aims to evaluate the effects of low-dose gamma radiation on expression changes of apoptotic genes(bax and bcl-2) in the rat peripheral blood lymphocytes.In this experimental study,...
In this paper, we study the different types of cooling and freezing stores that can actually be used to store and preserve foodstuffs, as well as the types of heat-insulating materials and moisture-insulating materials that are used in the structural composition of these stores, in addition to the method of calculating the various items that constitute the thermal load of these stores. For the purpose of evaluating and calculating the thermal loads of cold stores in big Market for storing...
This research paper aims to study the effects of heat treatment on 14 mm reinforcing bars that are produced by the Libyan Iron and Steel Company. These operations were conducted in the quality control laboratory, and it was found that there are two types of 14 mm reinforcing bars: (G-40) and (G- 60). The difference between them is the percentage of carbon present in their chemical composition, as the percentage of carbon in the variety (G-40) ranges between 0.25% and 0.38%, and as for the...

The performance characteristics of an open-cycle solar assisted desiccant cooling system were evaluated using computer simulation. A computer program was built and developed to simulate the effect of various design and operating conditions on the performance of the individual components making up the simulated system. They include a V-corrugated plate type solar air heater, a rotary silica gel desiccant dehumidifier, a sensible cooler and an evaporative cooler. The overall system performance...

The performance characteristics of a V-corrugated plate type solar air heater was investigated analytically using computer simulation. A Visual Basic computer program was built to predict the hourly instantaneous collection efficiency, useful energy gained and the outlet air temperature of the solar air heater. The effects of various design and operating conditions, such as mass flux, wind speed, absorber plate emissivity, and collector tilt angle and inlet air temperature, on the predicted...
This study aims to examine risk management in Libyan construction projects during periods of political unrest, measuring the frequency and severity of political, security, economic, and logistical risks, identifying effective mitigation strategies, and assessing stakeholder perceptions. Using a mixed — methods approach—including surveys of 150 construction firms, interviews with key stakeholders, and statistical analysis—the research evaluates how political instability disrupts project...
