Bluetooth technology is an emerging wireless networking standard, which is based on chip that provides short-range wireless frequency hopping communication. Now, Bluetooth technology is mainly applied to the communication between mobile terminal devices, such as palm computers, mobile phones, laptops and so on. However, the phenomenon of data-leaking frequently arises in using the Bluetooth technology for data transfer. To enhance the security of data transmission in Bluetooth communication, a hybrid encryption algorithm based on DES and RSA is proposed. The currently used encryption algorithm employed by the Bluetooth to protect the confidentiality of data during transport between two or more devices is a 128-bit symmetric stream cipher called E0. The proposed hybrid encryption algorithm, instead of the E0 encryption, DES algorithm is used for data transmission because of its higher efficiency in block encryption, and RSA algorithm is used for the encryption of the key of the DES because of its management advantages in key cipher. Under the dual protection with the DES algorithm and the RSA algorithm, the data transmission in the Bluetooth system will be more secure. This project is extended with triple des in place of des to enhance more security.

The properties and potentials of soils of Liman Katagum (LK) in Bauchi State were assessed for both rainfed and irrigated crop production. Six soil mapping units were identified. The soils were moderately deep to very deep (93 – 163cm), except for exposed petroplinthite in some part of land unit LK 2. Soil pH ranged between 4.7 and 8.4, and was rated moderately acid to moderately alkaline. The soils were characterized by moderate fertility status. Improved management techniques were suggested for sustainable use of the land to improve farmers’ economy in the area. Assessment of the land potential showed that land units LK 3, LK 5 and LK6 (47.5%; 9.975ha) were moderately suitable (S2) and LK 1 and LK 4 (27.5%; 5.775ha) marginally suitable (S3) for rainfed crop production. For irrigated crop production, land units; LK 3, LK 4, LK 5 and LK 6 (51.43%; 10.8ha) were potentially moderately suitable (S2) and Land unit LK 1 (23.57%; 4.95ha) marginally suitable (S3). Land unit LK 2 constituting 25% (5.25ha) of the land was not potentially suitable (N2) for either rainfed or irrigated agriculture.

This paper is a study with the actual situation of thermal power plant for increasing the safety measure by which the failure rate of the components of stacker cum reclaimer in the thermal power plant, used for coal handling can be reduced. This study is made to reduce the chances of failure in the components of a stacker cum reclaimer by using several safety measures and installing various safety devices.

Recently, concern over agricultural diffuse pollution sources in integrated water quality management has been growing. High inorganic and organic fertilisers application rates may increase groundwater pollution and these effects were investigated in the Dufuya Wetland (19o17’S; 29o21’E) in Chief Sogwala area of Lower Gweru Communal Lands, approximately 42km west of the City of Gweru, Zimbabwe. Forty-two (42) water samples were collected for analysis of pH, conductivity, calcium, nitrates, and phosphates during the months of September, October, and November 2008. A questionnaire procedure was used for collection of manure application rate, wetland and crop management data in the studied area. The results demonstrated that cattle manure in the Dufuya wetland is applied at the rate of 30t/ha- 60t/ha per year. Groundwater and surface runoff water samples have pH, conductivity, calcium, phosphates and nitrates levels within the WHO permissible guideline of 6.5-8.5, 1500µScm-1, 200mg/l, 0.09mg/l and 10mg/l respectively. The mean nitrate and phosphate concentrations in surface run-off water in the garden and the sponge are 0.00275mg/l, 0.0117mg/l and 0.00377mg/l, 0.00077mg/l respectively. Groundwater concentrations are 0.026mg/l, 0.0167mg/l and 0.0021mg/l, 0.00228mg/l for nitrates and phosphates respectively. There was no significant difference in the mean concentrations of nitrates and phosphates in water (ground/surface) in the sponge and the garden (P < 0.005). Fertiliser applications have no negative effects on dambo water quality.

Aquaculture products can harbor pathogenic bacteria which are part of the natural microflora of the environment. A study was conducted aiming at the isolation of human pathogenic bacteria in gills, intestines, mouth and the skin of apparently healthy fish, Tilapia rendali and Oreochromic mossambicus, from the Fletcher dam. Bacterial pathogens associated with fish can be transmitted to human beings from fish used as food or by handling the fish causing human diseases. Differentiation and characterization of various isolates was based on their growth characteristics on specific culture media (biochemical and gram staining reactions). The following human pathogenic bacteria were isolated Salmonella typhi, Pseudomonas aeruginosa, Escherichia coli, Staphylococcus aureus, Vibrio cholerae, Shigella dysenteriae and Enterococcus faecalis. All the bacterial species which were isolated from the fish were also present in the initial water samples collected. The isolation of enteric bacteria in fish serves as indicator organisms of faecal contamination and or water pollution. Their presence also represents a potential hazard to humans. The mean bacterial load of the isolates was found to be markedly higher than the recommended public health and standard value of 5.0 x 106 CFU/ml which has been adopted by many countries.
