Market research in fast food restaurant sector
No full textThis is a research based thesis which focuses on market research in fast food restaurants. The main purpose of this research is to understand customer’s expectations in terms of services, menu items, and related ethical aspects. Another objective of this thesis is to evaluate the challenges for a startup restaurant based on market analysis of existing fast food market in capital region of Finland.
The detailed study of different market research methods was performed to develop the market research methodology suitable for the fast food restaurant business. After thoroughly studying different market research methods, the research was divided into two levels: micro and macro. The micro level market research focused on the factors which can be controlled by the entrepreneur, while the macro level market research focused on the factors which cannot be controlled by the entrepreneur.
For micro level market research, qualitative research approach was used to understand the factors which can help to attract the customers in fast food business. The non-participant observation method was employed to rate and record customer satisfaction for this purpose. This observation was performed in international fast food chain located in capital region of Finland. For macro level market research, quantitative and qualitative research approaches were used to understand the challenges for a startup restaurant. The PESTEL and Porter’s Five Forces analysis tools were used in this case.
Market research results are quite encouraging for restaurant business in Finland during the past few years. The analysis of these results confirms that opening a fast food restaurant in the capital of Finland has good chance of success. The author recommends to include hamburgers in the menu and allow the customers to see the preparation process and customize the ingredients according personal choices

Pemphigus vulgaris in oral cavity: A case report
No full textPemphigus vulgaris is an autoimmune disease that produces intraepithelial blisters in the skin and the oral mucosa. The
oral mucosa is often the first site to be affected by the disease. Initial lesions could appear in the oral cavity in the form
of vesicles, bullae and ulcers. Dentists have a major role in the recognition and diagnosis of this disease. A case of oral
pemphigus vulgaris is presented with special emphasis on diagnostic modalities.Corresponding Author:

Representations of South African Indian women in Farida Karodia's Daughters of the twilight and Shamim Sarif's The world unseen.
No full textThesis (M.A.)-University of Natal, Durban, 2003.In this article I examine the representations of South African Indian women in Farida
Karodia's Daughters of the Twilight and Shamim Sarif's the world unseen. My contention
is that each author chooses a different mode of representation and that certain features
of these representations suggest both the different relationship each author has with
South Africa and the differences in the times of production of the novels. Thus while both
novels are set in the 1950s, Karodia, whose site of enunciation is the 'interregnum' in the
1980s, imagines the agency of her women quite differently from Sarif, who writes from a
'post-anti-apartheid' site of enunciation in the late 1990s. I analyse and compare the
relationships between characters (men and women; women and women) and look at the
cultural and political significance of mixed-race figures, concentrating on uncovering the
mechanisms of power and their effects. I read these against a politico-historical context
of the setting and that of the times and places of production
Thermodynamic analysis of solar-based photocatalytic hydrogen sulphide dissociation for hydrogen production
No full textThe dissociation of gaseous hydrogen sulphide (H2S) into its components is an energy intensive process. The process is studied in this paper with respect to the thermodynamic limits. The band gap of the catalyst and the nature of the solar radiation limit the proportion of incoming radiation that may be used for the reaction. The intensity of the incoming radiation and the reactor temperature are varied and the performance is studied. The exergy efficiency is determined as a function of the quantum efficiency of the photochemical process, and the catalyst band gap. It is shown that an optimum case exergy efficiency of up to 28% can be achieved for the process. With the current status of technology, an exergy efficiency value in the region of 0.4–1% is calculated, with a short-term improvement potential of up to 10%. Hydrogen sulfide has high energy content, but is not widely used due to its impact on environmental pollution. The proposed process in this paper is attractive as it allows that energy to be utilized, while degrading the highly toxic gas into less harmful products

Experimental investigation of a solar tower based photocatalytic hydrogen production system
No full textIn this paper, production of hydrogen from concentrated solar radiation is examined by a laboratory scale solar tower system that is capable of handling continuous flow photocatalysis. The system is built and studied under a solar simulator with an aiming area of 20 × 20 cm2. The fraction of solar spectrum useful for water splitting depends on the energy band gap of the selected photocatalyst. Two types of nano-particulate photocatalysts are used in this work: ZnS (3.6 eV) and CdS (2.4 eV). The effect of light concentration on photocatalysis performance is studied using Alfa Aesar 99.99% pure grade, 325 mesh ZnS nano-particles. An improved quantum efficiency of 73% is obtained as compared to 45% with the same sample under non-concentrated light in a previous study. Only 1.1% of the energy of the solar radiation spectrum can be used by ZnS catalyst. A mixture of CdS and ZnS nano-particulate photocatalysts (both Alfa Aesar 99.99% pure grade, 325 mesh) is used to conduct a parametric study for a wider spectrum capture corresponding to 18% of the incident energy. Hydrogen production increases from 0.1 mmol/h to 0.21 mmol/h when the operating conditions are varied from 25 °C and 101 kPa to 40 °C and 21 kPa absolute pressures. Furthermore, the implementation of a continuous flow process results in an improvement in the energy efficiency by a factor of 5.5 over the batch process
