Abstract Gas turbines provide a reliable and efficient production of power in both pilot power plants and aircraft propulsion. The operating cost of the modern gas turbines is greatly influenced by the durability of hot section components. To cope up with the increasing temperature, there has been an evolution of new generation blade materials. At elevated temperature conditions, thermal stress and resulting deformations can affect the power developed and efficiency. In this paper a finite element simulation has been made on a fixed blade profile to explore various factors affecting the turbine blade. Variety of existing and new generation materials have been considered a under a boundary condition of constant high pressure and high Operating temperature was varied between 1000°C-1400°C. The development of stress and deformation along with the heat flux have been studied for finding the most effective manufacturing alloy for gas turbines.

The leading implementers of the curriculum and educational system are teachers, so the success and failure of the educational system depend mainly on its teachers. If teachers have an established professional identity, it leads to the success of the educational system. Professional identity, like other aspects of the teaching and learning process, is influenced by various factors. Investigating this concept requires identifying the factors affecting it. One of the most important factors that influence teachers' professional identity is teachers' emotions. Teachers' emotions also can have a significant impact on teachers' performance. After searching the databases, this review article examines the role of teachers' emotions and their professional identities in English as a foreign language (EFL) or English as a second language (ESL) classrooms. This review paper unpacks that factors such as teachers' pedagogical beliefs, their positive and negative emotional experiences, their environmental and cultural factors, and their perceptions and expectations of these conditions could affect their emotions as well as their professional identity. Teachers' identity is shaped through ongoing negotiation and interaction that encompasses their personal and professional lives. Taking these factors into account in teacher training courses might notify teachers of the challenges that they might have in their classrooms and provide them with practical solutions.

Of all the external factors affecting a gas turbine, inlet pressure and temperature have the greatest impact on performance. The effect of inlet temperature variations is especially pronounced in the new generation of high-efficiency gas turbines typified by the 40 MW GE LM6000. A reduction of 50 F (28 C) in inlet temperature can result in a 30% increase in power and a 4.5% improvement in heat rate. An elevation increase to 5000 feet (1524 meters) above sea level decreases turbine output 17%; conversely supercharging can increase output more than 20%. This paper addresses various means of heating, cooling and supercharging LM6000 inlet air. An economic model is developed and sample cases are cited to illustrate the optimization of gas turbine inlet systems, taking into account site conditions, incremental equipment cost and subsequent performance enhancement.

In recent years, an increasing number of non-native EFL teachers have been recruited to teach English in English dominant settings. Grounded in sociocultural views of identity, the research question of this study focused on how contextual factors influence the professional identity construction of three EFL teachers in a Saudi School in Kuala Lumpur, Malaysia. The study employs a qualitative case study method, where in-depth interviews and classroom observation are utilised. Drawing on Wenger’s (1998) communities of practice framework to analyse and interpret the data, the analysis indicates various factors affecting the EFL Saudi teachers’ professional identity. Findings reveal that identity formation is a complex and highly contextual process. The participants in this study construct their identities by engaging in their teaching environment, shared practices with their peers, engaged in student-parents relationship and participated in professional development. Through transitioning into the English as a second language (ESL) setting, the EFL teachers have demonstrated how professional identity is a dynamic and socially situated construct. As a result, these teachers’ identities may be transformed by the global educational settings in which they work. The findings contribute to our understanding of the importance of a conducive professional environment in supporting teachers to develop their professional identities.

Significant research and development in the field of biomedical implants has evoked the scope to treat a broad range of orthopedic ailments that include fracture fixation, total bone replacement, joint arthrodesis, dental screws, and others. Importantly, the success of a bioimplant depends not only upon its bulk properties, but also on its surface properties that influence its interaction with the host tissue. Various approaches of surface modification such as coating of nanomaterial have been employed to enhance antibacterial activities of a bioimplant. The modified surface facilitates directed modulation of the host cellular behavior and grafting of cell-binding peptides, extracellular matrix (ECM) proteins, and growth factors to further improve host acceptance of a bioimplant. These strategies showed promising results in orthopedics, e.g., improved bone repair and regeneration. However, the choice of materials, especially considering their degradation behavior and surface properties, plays a key role in long-term reliability and performance of bioimplants. Metallic biomaterials have evolved largely in terms of their bulk and surface properties including nano-structuring with nanomaterials to meet the requirements of new generation orthopedic bioimplants. In this review, we have discussed metals and metal alloys commonly used for manufacturing different orthopedic bioimplants and the biotic as well as abiotic factors affecting the failure and degradation of those bioimplants. The review also highlights the currently available nanomaterial-based surface modification technologies to augment the function and performance of these metallic bioimplants in a clinical setting.
