DETRIMENTAL CAUSES AND CONSEQUENCES OF ORGANIZATIONAL INJUSTICE IN THE WORKPLACE: EVIDENCE FROM PUBLIC SECTOR ORGANIZATIONS

This study investigated the causes of organizational injusticeand how this influences employees’ job outcomes in public sectororganizations in Pakistan. Two models were constructed and analyzed to fulfill the research goals. Data were obtained using a simple random sampling technique. Of the sample, 254 employees of public sector organizations filled out self-administered questionnaires. Multiple regression was applied to test direct proposed hypotheses. To evaluatethe organizational injustice’s indirect effect on organizationalperformance due to employees’ job dissatisfaction, the mediation test of Preacher and Hayes (2004) was applied. The results showed that organizational injustice negatively impacts affective commitment and perceived organizational performance. Moreover, job dissatisfaction impacts the relationship in organizational injustice, perceived organizational performance and affective commitment

The Effects of Processing Parameters on Defect Regularity in Ti-6Al-4V Parts Fabricated By Selective Laser Melting and Electron Beam Melting

Processing parameter has an important effect on Selective Laser Melting (SLM) and Electron Beam Melting (EBM) processes. Defects are easily formed by deviating from optimized processing parameters. This study purposely fabricated Ti-6Al-4V specimens with defects by varying process parameters from the factory default settings in both SLM and EBM equipment. Specimen’s density was measured based on the Archimedes method for estimating porosity. Microscopy of specimen’s top surface were observed to compare melt pool and overlap. “Marginal Parameters” is identified to describe the processing parameters which are capable of fabricating specimens with certain porosity. As a result, a correlation between defect regularity and marginal parameters has been established. The effect of marginal parameters on the melt pool is discussed to explain defect formation.Mechanical Engineerin

Defect Formation in EBM Parts Built in Horizontal Orientation

EBM built parts in a horizontal orientation, particularly with bottom curved surfaces, are prone to variations in dimensional accuracy and defect formation. These defects likely occur due to the nature of the supports utilized and the build strategy. To understand the effect of support structures and scan direction on these defects, a series of cylindrical parts were built using different diameters, support structures and scan strategies. The as-built samples were mechanically tested and sample cross sections were analyzed. Pore formation and balling effects were observed in the lower section of some samples. The study looks at the effects of supports, geometry and scan strategy on the minimization of these defects and improving the dimensional accuracy of horizontally built samples.Mechanical Engineerin

An Investigation into the Enhancement of Condensate Recovery from Retrograde Gas Condensate Reservoirs

The loss in condensate recovery from gas condensate reservoirs due to condensate dropout when the flowing bottom hole pressure drops below the dew point pressure of the in-situ reservoir fluid is significant. Pressure maintenance and gas cycling are the standard practices used to alleviate this problem and enhance the condensate and gas recoveries. In this study, swelling and constant volume depletion tests are conducted on the original fluid sample from a gas condensate reservoir. Various scenarios regarding gas injection recycling are examined to determine the most appropriate gas for injection which enhances gas and condensate recovery. In this study, injection of three gases (CO2, N2 and separator gas) with different injection volumes on the current field fluid were tested using simulation. Based on the results of this study, CO2 was the most efficient gas followed by separator gas and N2 respectively to inject into the gas condensate reservoirs for decreasing the condensate dropout and enhancing its recovery. This result is significant as CO2 injection in gas condensate reservoirs could be used to sequestrate the produced CO2 from power plants and other sources while enhancing the production from gas condensate reservoirs

High Temperature Superconductors

One of the pioneers who introduced superconductivity of metal solids was Kamerlingh Onnes (1911). Researchers always struggled to make observations towards superconductivity at high temperatures for achieving goals of evaluating normal room temperature superconductors. The physical properties are based entirely on the behavior of conventional and metal superconductors as a result of high-temperature superconductors. Various synthetic approaches are employed to fabricate high-temperature superconductors, but solid-state thermochemical process which involves mixing, calcinating, and sintering is the easiest approach. Emerging novel high-temperature superconductors mainly engaged with technological applications such as power transmission, Bio-magnetism, and Tokamaks high magnetic field. Finally, in this chapter, we will discuss a brief outlook, future prospects, and finished with possible science fiction and some opportunities with high-temperature superconductors

Structural Analysis and material selection for biocompatible cantilever beam in soft robotic nanomanipulator

This paper investigates the selection of appropriate materials for cantilever beams in surgical robotic nanomanipulators. Cantilever beams play a crucial role in soft robotic surgery. Biocompatible materials, which have minimal adverse effects on biological systems, are commonly used for these beams. Using SOLIDWORKS software simulation, the study assesses the flexibility of cantilever beams made from different biocompatible materials. The analysis involves varying the applied force (0.001 µN to 0.004 µN), beam length (80 µm, 120 µm, and 160 µm), and beam thickness (0.4 µm, 0.6 µm, and 0.8 µm). Four materials—Alumina, Poly-Ether-Ether-Ketone (PEEK), Polyurethane (PUR), and Ti-6Al-4V—are evaluated. Simulation results highlight Polyurethane (PUR) as a suitable material for cantilever beams in nanomanipulators due to its favorable properties. These findings provide valuable insights for the design and advancement of efficient and reliable robotic nanomanipulators, advancing the field of soft robotic surgery

Botanical Insecticides Are a Non-Toxic Alternative to Conventional Pesticides in the Control of Insects and Pests

Insect control for crops is one of the most critical global concerns. Pest management is an economic and ecological problem worldwide due to the human and environmental risks raised by most synthetic pesticide products. Botanical insecticides have resurfaced in popularity due to their low cost and low environmental impact, rather than their negative effects on human health. Botanical insecticides destroy only the insects they are meant to kill, leaving no residue on food or in the environment. Botanicals have long been used to combat pests. The compounds have many environmental advantages. However, as opposed to other bio-control pests and pathogens, their use was minimal during the twentieth century. In developing countries, botanical insecticides are well adapted for use in organic food production. Nonetheless, they may play a far bigger role in developed countries’ food production and post-harvest food protection. Consequently, the current chapter briefly addresses botanicals with active ingredients with insecticidal, antifeedant, or repellent properties
