Abstract: The research is about the customer service experience and how it affects the buying behavior of customers of Aswaq Al Awafi and Gulfmart. The research confirmed that there are 3 important aspects of customer service which are staff behaviour, expertise on products and service information and staff availability. The buying behaviour of the customers is influenced by how good or how bad their experiences are. These three factors lead to customer satisfaction. Findings also emphasized the necessity to ensure that staff or employees meeting customers in the front line on a daily basis should develop a successful relationship with the customers. Buying behaviour is influenced by the customer service experience. A good customer experience promotes positive result for the supermarket as they continue to come back for their needs even after 2 years of good experience. However, a bad customer service will drive customers away and will result to negative image as they tend to share their bas experiences with other people. Overall, customer service affects buying behaviour which at end results to customer loyalty.

Keywords: Staff availability, staff behaviour, buying behaviour, customer satisfaction, customer loyalty, product and service expertise.

Abstract: The effects of changes in ratios of n-alkane precipitants on the quantity of heavy organics precipitated at wellhead, separator and flowline during petroleum production was studied. Crude oils from three (3) wells at Sapele oil field, Niger Delta, Nigeria, were sampled. Gravimetric titration with single and corresponding binary mixtures of low molecular weight n-alkane precipitants (C5 and C6) at different ratios was used to generate the heavy organic precipitates. The results obtained from the 0:1, 1:3, 1:2, 1:1, 2:1, 3:1 and 1:0 ratios of C5:C6 binary mixtures of precipitants showed a consistent increase in the quantity of heavy organic precipitate at wellhead while the Separator recorded the least in all the three reservoirs. From the result obtained, it is important to closely monitor the operational pressure and temperature at the different locations of the production system and to ensure that the operational pressure and temperature at wellhead is higher than that of the flowline and that of flowline higher than the separator to prevent heavy organic precipitation and deposition.

Abstract: In Kenya's social media, Nairobi Swahili is the norm for communication in institutions of higher learning. Extant studies dwells on standard Swahili, affording limited text classification literature for Nairobi Swahili Natural Language Processing. The research explores how social media experience provides new ways for interactions, resulting into new challenges in managing student concerns that now require new knowledge for decision-making. Students have taken advantage of social media platforms by creating virtual discussion forums, which are quickly becoming repositories of collective knowledge. Unfortunately, institutions of higher are not able to utilize the collected knowledge through these platforms. The focus of this research is to ensure knowledge generated via social media is useful through opinion mining to enable extraction, classification and storage to support decision-making. Different algorithms were tested utilizing data from popular social media; operated by students in Kenyan universities. The results showed that SVM gives the best results when used with Linear Kernels and better performance on TF-IDF with N-grams methods. An analysis on the different SVM kernel showed linear kernel to have a better performance at 80% compared to Polynomial kernel and Radial Basis Function kernels, which both stand at 57%. To choose the best feature selection method for use along with linear SVM, TF and TF-IDF were tested. TF-IDF performed better with N-grams at 83%; rendering this research both theoretical and practical significance. The research would provide fast hand information for decision support in Kenyan higher learning institutions using text-mining tools in social media.

Abstract: Bubble deck slab is a method of virtually eliminating all concrete from the middle of a floor slab, which is not performing any structural function, thereby dramatically reducing structural dead weight. High density polyethylene hollow spheres replace the in-effective concrete in the center of the slab, thus decreasing the dead weight and increasing the efficiency of the floor. The advantages are less energy consumption - both in production, transport and carrying out, less emission - exhaust gases from production and transport, especially CO2 and reduce the material, the load, lower the cost and it is also a green technology. In the bubble deck technology reduce the concrete volume by replacing the spherical bubbles, these are locally available which is called as PEPSI balls, these balls are made up of HDPE (High Density polyethylene). In this experimental program conventional slab and bubble deck slab are cast with various bubbles arrangement which is continuous arrangement of bubbles within whole slab and two types of alternative bubbles arrangement in the slab. And trying to enhance the increasing strength of that slab. This implies the realization of a monolithic slab element, which will be subjected to static gravitational loadings in order to determine the load carrying capacity of the slab, deformation (deflection), cracking and failing characteristics. The resultant conclusions will be used in defining the failing mechanisms and advantages of the bubble deck slab are highlighted.

Abstract: Water conservation is important for 'ecological sustainability' therefore what we consume needs to be replenished back in some way. Rainwater harvesting (RWH) system is one such conservation policy and it uses the principle of conserving rainwater. In the process we help in the recharge of groundwater. Traditional RWH systems were built to suit the specific environments in which they evolved and worked efficiently in different economic and political environments. The issue of water is not about scarcity but about its careful use and its equitable and distributed access. Water is our basis therefore water conservation is the need of the hour. Illegal boring has led to depletion of groundwater reserves. Not only this but urban water bodies which served the needs of the city since early times are now dump yards for garbage and refuse. Since surface water bodies are getting polluted by the day and usage of this water is only possible after thorough treatment, people opt for ground water resources since treatment of water is also an expensive proposition. Lessons can be derived from traditional practices of water usage and its conservation. To be able to implement RWH techniques in the present day we can look at some traditional rainwater harvesting systems in various parts of India to get a few practical lessons in the methodology. Lessons can be taken from places like Zings of Ladakh, Khuls of Jammu in NorthIndia, Naula or Hauzi in the hills of Uttar Pradesh, practices of Northeastern states like Mizoram, Meghalaya and Nagaland, The Baoris, jhalaras and tankas of Rajasthan and kulams of Tamil Nadu. The Research paper will emphasize on the traditional methods of rainwater harvesting and their regional innovations from which the practice of rainwater harvesting is applicable in the urban situations of the country. This will be aimed at achieving not only water conservation but also restoration of traditions and clues for working out desirable solutions.
