Abstract:
A new approach of oxidation of carbon nanotubes has been used to oxidize the CNTs. A comparative aspect of the mechanical oxidation and acid oxidation process has been established. FTIR analysis and titration method have shown the higher feasibility of the mechanical oxidation method to oxidize the CNTs. Comparatively less damage to the CNTs has been observed in case of mechanically oxidized as compared to acid oxidized CNTs. The mechanical properties of the nanocomposites reinforced with the acid oxidized CNT (ACNT) and mechanically oxidized CNTs (McCNT) were analyzed and relatively higher properties in the nanocomposites reinforced with McCNT were noticed. The less degree of entanglement in the McCNTs was noticed as compared to ACNTs. The dynamic mechanical analysis of the nanocomposites revealed much improved load transfer capability in the McCNT reinforced composites. Further, the rheological properties of the nanocomposites revealed the higher performance of McCNT reinforced composites.

This review covers the recent advances in the synthesis and function of interlocked rotaxanes with mechanical chirality along with their dynamic and complex stereochemistry. The application of mechanically chiral rotaxanes to control the polymer helical structure is also introduced, where amplification of mechanical chirality appears to cause the macroscopic polymer property change, suggesting the potential applicability of mechanical chirality in polymer systems.

Abstract:
Abstract Glass reinforced plastics (GRPs) are composite materials that have been used widely in engineering. Mechanical properties of fabricated GRP products depend on the type and arrangement of reinforcement, the type of the plastic as well as the reinforcement to plastic ratio. Some of these factors are interdepended in determining the quality of the final product. In the present study, the influence of applying mechanically a slight pressure during fabrication on the properties of GRP specimens, was investigated. Specimens were fabricated using the hand lay-up method and were further processed either by a vacuum bag compression or a mechanically applied pressure. The properties of the produced composite specimens were then determined experimentally. The application of mechanical compression was found to improve their properties. The effect of the mechanically applied compression or vacuum was evident as a reduction of the specimens’ internal void volume compared to the non-compressed ones, resulting in an increase in the density by 9–12% and a reduction in the thickness of the specimens by 15–20%. Additionally, the tensile and flexural strength of the specimens were increased by more than 15% and 5% respectively when pressure was applied mechanically, reflecting an improvement in GRPs’ mechanical properties.

Abstract:
Mechanical ventilation provides lifesaving support for patients with acute respiratory failure. However, the pressures and volumes required to maintain gas exchange can cause ventilator-induced lung injury. The current approach to mechanical ventilation involves attention to both tidal volume and airway pressures, in particular plateau pressures and driving pressures. The ventilator provides energy to overcome airway resistance and to inflate alveolar structures. This energy delivered to the respiratory system per unit time equals mechanical power. Calculation of mechanical power provides a composite number that integrates pressures, volumes, and respiratory rates. Increased levels of mechanical power have been associated with tissue injury in animal models. In patients, mechanical power can predict outcomes, such as ICU mortality, when used in multivariable analyses. Increases in mechanical power during the initial phase of ventilation have been associated with worse outcomes. Mechanical power calculations can be used in patients on noninvasive ventilation, and measurements of mechanical power have been used to compare ventilator modes. Calculation of mechanical power requires measurement of the area in a hysteresis loop. Alternatively, simplified formulas have been developed to provide this calculation. However, this information is not available on most ventilators. Therefore, clinicians will need to make this calculation. In summary, calculation of mechanical power provides an estimate of the energy requirements for mechanical ventilation based on a composite of factors, including airway resistance, lung elastance, respiratory rate, and tidal volume.

Abstract:
In order to model and optimise the structural parameters of the working parts of agricultural machines, including harvesting machines, the mechanical properties of the culture harvested must be known. The purpose of this article is to determine the mechanical properties of the blueberry plant’s stem; more precisely the tensile strength and consequent elastic modulus E. In order to achieve this goal, the measuring instrument Instron 5969L2610 was used and accompanying software BlueHill 3 was used for analysing the test results. The tested blueberry plant’s stems were collected from the blueberry plantation of the Farm Marjasoo. The diameters of the stems were measured, test units were prepared, tensile tests were performed, tensile strength was determined and the elastic modulus was obtained. Average value of the elastic modulus of the blueberry (Northblue) plant’s stem remained in the range of 1268.27–1297.73 MPa.

Abstract:
This paper describes a mechanical mechanism of chemical mechanical polishing (CMP) and the model is applied to the polishing of silicon substrates by polyurethane pads and slurries containing fumed silica as is typically done in the manufacture of integrated circuits. The model utilizes the concept that the polishing pad surface contains asperities that support the normal load on the wafer, and that friction and hydrodynamic forces influence wear. The interfacial fluid pressure can significantly influence the normal pressures on the wafers and its effects modify the wear rate predictions.

Abstract:
A variety of seemingly diverse pain syndromes are characterized by movement-induced pain radiating in the distribution of a peripheral nerve or nerve root. This could be explained by the induction of ectopic mechanical sensitivity in intact sensory axons. Here we show that inflammation led to mechanical sensitivity of the axons of a subset of mechanically sensitive primary sensory neurons. Dorsal root recordings were made from 194 mechanically sensitive neurons that innervated deep and cutaneous structures and had C, Aδ, and Aαβ conduction velocities. No axons of any category were mechanically sensitive in control experiments. However, the axons of neurons innervating deep structures and having C- or Aδ-conduction velocities became mechanically sensitive during the neuritis, and also exhibited an increased incidence of spontaneous discharge. The incidence of mechanical sensitivity followed a distinct time course. In some cases, paw withdrawal thresholds were obtained after neuritis induction. The time course of the resultant hypersensitivity was not directly related to the time course of the axonal mechanical sensitivity. Ectopic axonal mechanical sensitivity could explain some types of radiating, nerve-related pain coexisting with diseases of seemingly diverse etiologies.

Abstract:
PID controller is one of the most widely used control elements in the industry. Over history, people have implemented the PID controller mechanically with pneumatical components, electronically in circuits, or digitally using DSP. However, the pure mechanical realization of PID controllers is rarely studied. This paper presents an analog PID controller based on mechanical computation components, including a mechanical integrator, a mechanical differentiator, mechanical constant multipliers, and a mechanical adder. In this work, those parts are studied respectively with CAE modeling and mathematical derivation. A novel design of mechanical differentiator is also introduced to conduct the calculation of the differential part on the PID controller. This work explores the theoretical possibility of a new form of PID controller realization, that is, applying the method of mechanical analog computation to the implementation of a PID controller.

During the last few years, efforts have been made to improve the properties of tungsten carbides (WCs) by preparing composite materials. In this study, we prepared WC particles by mechanical alloying and investigated the effects of mechanical alloying conditions, such as mechanical alloying time and mechanically alloyed powder ratio, on the properties of 94WC-6Co. According to experimental studies, increasing the mechanical alloying time causes an increase in the density of tungsten carbide samples and a decrease of crystal sizes and inner strength of the prepared materials. With the increase of mechanical alloying time, fine particle concentrations of tungsten carbide samples have increased. It is observed that increasing the mechanical alloying time caused a decrease of the particle surface area of tungsten carbide samples. Besides, the amount of specific phases such as Co3W3C and Co6W6C increases with increasing mechanical alloying time. As another subject of this study, increasing the concentration of mechanically alloyed tungsten carbides caused an increase in the densities of final tungsten carbide materials. With the concentrations of mechanically alloyed materials, the occurrence of Co6W6C and Co3W3C phases and the increase of crystallization are observed.

Abstract:
It is increasingly evident that there is little data available to compare the use of various modes of mechanical ventilation or to assess their application. It is difficult to compare the new modes of mechanical ventilation with the conventional modes because of a similar lack of clinical data. The challenge for future research in the area of ventilator technology is to generate controlled clinical studies to support its application. With the increased impact of financial constraints on healthcare, research will also need to examine the economic issues related to the application of newer modes of mechanical ventilation. The critical care nurse will be faced with the continued challenge of being knowledgeable regarding the current trends in ventilatory support and their potential advantages and disadvantages, while keeping in perspective those areas where clinical research is lacking. Possibilities for future nursing research related to mechanical ventilation are endless. The application and refinement of assessment parameters to evaluate the impact of nursing interventions on mechanically ventilated patients should be a key focus. The growing use of SVO2 monitoring in conjunction with other assessment parameters may prove to be useful tools to measure the impact of interventions such as suctioning, positioning, muscle reconditioning, weaning techniques, and comfort measures on mechanically ventilated patients.
