Tracheoesophageal fistulas (TOF) are a rare but sometimes a severe complication of tracheotomy. Their clinical presentations, of varying severity, usually involve several symptoms. The diagnostic procedure always combines chest x-rays looking for a pneumothorax, a pneumomediastinum or an aerogastry, and bronchial fibroscopy which determines the location, size and potential severity of the lesion. Therapeutic management is based on surgical repair. Prevention of TOF is important and must represent the real treatment.

The issue on branding has been always the talks of the large-sized companies. This has been addressed in many literatures. But, these literatures little or never discussed about branding for small-medium enterprises (SMEs). Many view that branding is not the subject of SMEs around the world. The SMEs play a significant role in the development of economy especially the developing economies around the world. Hence it’s very important for every economy to focus and develop the SMEs. Effective branding is a key factor for the success of the SMEs. Effective brand development takes time. Once successful, similar, if not greater effort is required to sustain and enhance the position of the brand and the brand has to grow to remain strong. Our literature review suggests that the factors that affect branding of SMEs are the number of brands, brand equity, brand mix, consistency in brand communication, positive brand experience, brand differentiation, brand passion, push and pull brand campaign and secondary brand association.

The issue of ethical leadership have received significant interest in recent years due to plethora of ethical scandals in organizations. Thus, this paper aims to explore for better understand the determinants of ethical leadership. Even though many researchers attempt to explore and determine the antecedents and factors of ethical leadership, yet the determinants of ethical leadership is less convincing since the results evidenced to be mixed. Together with less intention given in Malaysia to explore the determinants, hence this paper could provide a conceptual framework that would help future research endeavour.

In the present paper, unsteady MHD flow past an impulsively started vertical plate with constant wall temperature and variable mass diffusion in the presence of Hall current is studied. The fluid considered is an electrically conducting, absorbing-emitting radiation but a non-scattering medium. The Laplace transform technique has been used to find the solutions for the velocity profile and skin friction. The velocity profile and skin friction have been studied for different parameters like Schmidt number, Hall parameter, magnetic parameter, mass Grashof number, thermal Grashof number, Prandtl number, and time. The effect of parameters are shown graphically and the value of the skin-friction for different parameters has been tabulated.

Communities with different profiles shows the interests of community members. User and check-in venue details are used to cluster. Multimode multi-attribute edge-centric coclustering model is help to discover overlapping the communities. Overlapping communities is used to repair by replacing each edge with its vertices in edge clusters. Intermode and intra mode features are helped to us for making the process. Three intra mode features are used in the community detection process. M2 Clustering algorithm is used for community detection it is Edge clustering based on k-means and HM2 Clustering algorithm is used to detect overlapping communities of LBSNs and also called as Two-step hierarchical edge clustering. The overlapping community detection mechanism is enhanced with recommendation models. LBSNs, analyzing 1) the data source used, 2) the methodology community. 3) the objective of the community. The community are also classified with location. The system is enhanced with feature selection and feature fusion mechanism. This system also indicate the cluster of the two communities.

OFDM systems are widely used in both wired and wireless communication systems. Fast Fourier Transform is one of the key processing in the implementation of OFDM systems such as wireless broadband, and ultra wideband systems. In most researches, the implementation of Fast Fourier Transform is focused on reducing the difficulties in multipliers, memory unit and control circuits involved in the FFT process. Modification in the architecture for pipelined FFT processor is proposed, to reduce the register size required for FFT processor. In OFDM, this FFT process is used at the receiver side of the system. The single-path delay-feedback architecture is used to exploit the spatial regularity in signal flow graph of the algorithm.

Over centuries the field of psychology has been dominated by men. For a long time, women have been labeled as inferior and men have dominated the field of psychology. Male superiority and dominance has infiltrated the social structure and reduced the role of the female in society. Myths of Social Darwinism based on sexual selection among other attributes saw the females struggle over centuries. There were many others who refuted this myth including Helen Thompson, Mary Calkins, and Mary Putnam Jacobi. Their theories include equity model and relational theory that has left the women fighting for equality based on early concepts of feminism. The main purpose of the paper is to investigate the history of women psychology and liberation of feminist in research and psychology. Narrative analysis of various literature from different nations on feminism, women and psychological research. The findings indicate that feminism is a thing of the past, there has been development in gender equality. Both men and women have been given equal chances in practicing psychology and more scholarships have been given out to women to encourage them to participate in research and psychology. Continuous empowerment has encouraged women to grow and develop their self-confidence, self-efficacy, and self-esteem.

Scientists all over the world have been concern for the earth due to the effect of climate change that has now become a matter of discuss. The effect of climate change is not only limited to several natural disasters such as Tsunami, melting of ice Berge, high rise water bodies etc. It has been agreed that mitigating the effect of climate change can be achieved through reforestation and replanting of trees in the forest. To ensure that climate change is mitigated holistically, all hand must be on deck. As such implementing the use of treated wood to forestall needless replacement of wood due to failure resulting from fungi decay and insect attack is another practical approach to ensure that the forest the major player in mitigating climate change is kept intact. It is therefore recommended that government policy should include ensuring that wood meant for building construction is given necessary treatment before installation to safeguard the integrity of the forest.

This paper investigated yield determinants among catfish farmers in Epe Local Government Area of Lagos State. A total of 65 catfish farmers were purposively selected for the study. The analytical technique employed include: Descriptive Analysis, Budgetary Analysis and Multiple Regression Analysis. Descriptive analysis was used to analyse the socio-economic characteristics;Budgetary Analysis was used to determine the profitability of the enterprise; and Multiple Regression Analysis was used to analyse the determinants of catfish yield in the study area. The various profitability ratios such as Expense Structure Ratio (0.76), Benefit Cost Ratio (3.13), Gross Revenue Ratio (0.45)and Rate of Return (0.96)indicated that catfish farming enterprise is profitable in the study area. The factors that significantly affect catfish output in the study area are: quantity of feed, quantity of labour, quantity of fingerlings and total pond size. Quantity of labour, quantity of fingerlings and total pond size had positive relationship with output of fish, while quantity of feed had an inverse relationship with yield output of catfish.

Due to public location and permanent availability multiple people depends on the automated teller machine (ATM). Due to that they can easily fall victim to manipulation. Frauds and security attacks based on observation by person or via various cameras also get increased. So, new methods for authentication mechanisms get developed to reduce the ATM security problems related to personal identification numbers (PIN). The user’s mobile phones play a central role in the trust establishment. Shift PIN entry away from possibly insecure ATMs PIN pad towards the user’s mobile phones & then transmit it securely for authentication. Dual tone modulated frequency (DTMF) plays a major role in this technique.
