The present work determined the possibility of using aluminium alloy 7075 material to design and manufacture a connecting rod for weight optimisation without losing the strength of the connecting rod. It considered modal and thermal analyses to investigate the suitability of the material for connecting rod design. The parameters that were considered under the modal analysis were: total deformation, and natural frequency, while the thermal analysis looked at the temperature distribution, total heat flux and directional heat flux of the four connecting rods made with titanium alloy, grey cast iron, structural steel and aluminium 7075 alloy respectively. The connecting rod was modelled using Autodesk inventor2017 software using the calculated parameters. The steady-state thermal analysis was used to determine the induced heat flux and directional heat flux. The study found that Aluminium 7075 alloy deformed more than the remaining three other materials but has superior qualities in terms of vibrational natural frequency, total heat flux and lightweight compared to structural steel, grey cast iron and titanium alloy.展开更多

Many of auto manufacturers in china have introduced some CAD/CAE/CAM systems in product development process, and have got some success. But the special and effi cient CAD system aimed at particular product is absent. This paper provides a CA D/CAE system that can realize the integration of CAD and CAE process for engine connecting rod development. The paper discusses some general methods in connecting rod design process, and s ums up structure characteristics of connecting rod. It introduces feature defini tion and feature classification facing connecting rod CAD/CAE system. Based on t he study of the feature technology and the feature of connecting rod, it creates the feature information model and feature database of engine connecting rod . In addition, it creates the parametric model of engine connection rod and real izes variable parametric design and variable structure design. With the help of Pro/Toolkit and Using C++ program to call the user ’s toolbox of Pro/ Engineer software system, the connecting rod CAD/CAE syst em can create connecting rod model automatically to meet the needs of different structure and different type of connecting rod. Based on Pro/Mechanica platform of PTC, the system can implements the Finite Ele ment Analysis and optimization of the connecting rod. Because using the same database in design and analysis, no data lost and no error occurs during da ta transforming. Using the connecting rod CAD/CAE system, the connecting rod can be meshed automatically and the FEA result can be achieved very fast and is very similar to the experiment. In a word, the connecting rod CAD/CAE system developed in this paper can optimiz e the product development process, realize the data share and concurrent enginee ring in the product design and analysis process, shorten the product develop ment circle, and improve the efficiency.展开更多

In the nursing profession, nurses are imbibed with the attributes of multicultural care competencies that would empower the nurses to be adaptive and mindful of how they provide and go with their carative nursing managements. This would entail that the non-Muslim nurses must be aware and be sensitive enough in their approaches and communicative exchanges with their Muslim patients. Objective: The study aims to identify the care approaches given by non-Muslim nurses working in the Arab world and how they elicit and provide a universal approach in caring Muslim patients. Methods: The study utilized a mixed methodology, specifically the explanatory sequential design, which involved a descriptive-comparative quantitative research design and eidetic qualitative research design. Results: Based on the result with the highest mean 3.63%, the respondents strongly agree that the non-Muslim nurse is aware of her own culture, 3.60% strongly agree that the non-Muslim Nurse does not discriminate the decisions of the patients regardless of gender, race, culture or belief and 3.58% still strongly agree that the non-Muslim nurse encourages patients to communicate as need arises. Here are three themes emerged from the study: understanding and respect of cultures, caring across borders, and caring calmness. In connecting the differences, non-Muslim nurses must be aware of their own culture, must not discriminate the decisions of the patients regardless of gender, race, culture or belief and must encourages patients to communicate as need arises. Conclusion: Knowing and understanding the scope of nursing practice with a high regard of respect to patients without discrimination will promote and provide holistic, safe and high-quality nursing care.展开更多

There is very limited information about the Lung associated channels in classical literature of TCM. With a clear focus on the function of respiration, we have carried out a detailed analysis of the biomedical consequence of stimulating the LUM, analysed the roles played by LUSC, LUDC, and LULCC. The updated LUM and LUDC include acupoints of other meridians, serving the same purpose of performing satisfactory respiration starting from checking the quality of the inflow through the nose. The LUSC includes the respiratory muscles (plus the associated connective tissues) extending to various parts of the body. The muscles of the limb (as part of the LUSC) embrace the nerves that provide routes for somatosensory reflexes and play the role of locomotion, providing voluntary respiration via the pectoralis muscles. The muscles of LUSC are bounded by stiff connective tissue layers, forming compartments, and are part of the pulley system for various body locomotions. Within a compartment, the interstitial fluid, blood, lymph flows must be potent to protect the associated nerves related to LUM;the healthy state of the LUSC also provides freedom of various types of locomotion. The LULCC exists because the vagus nerve has a part of it passing through the spinal cords all the way down to the sacrum domain, with exiting nerve innervating two-third of the large intestine.
