Fungal and bacterial contaminants of six spices and spice products in Ghana
The microbiological quality of two spices (aniseed and rosemary) and spice products (maggi onion cube, maggi shrimp cube, royco shrimp cube, royco beef cube) have been studied using conventional mycological techniques. The presence of moulds and yeast was compared on three media DRBC, OGYE, and PDA at 30°C incubated for 5 days. The species of fungi that were isolated from the raw spices and spice products...

Inhibitive effects of 2-mercaptobenzimidazole (MBI) and 2-thiobenzylbenzimidazole (TBBI) on copper corrosion in 1 M nitric acid solution
The inhibitive actions of 2-mercaptobenzimidazole (MBI) and 2-thiobenzylbenzimidazole(TBBI) on copper corrosion in 1M HNO3 medium were studied, using weight loss method, at 25 to 65°C and concentrations of 5.10-5M to 10-3M. The results showed that the two compounds had fairly good inhibiting properties for copper corrosion in the medium, with efficiencies of 90.0% for TBBI and 87.7% for MBI at...

Assessment of fluoride content in tropical surface soils used for crop cultivation
Bongo district of the Upper East Region of Ghana relies on groundwater as the main source of potable water supply for domestic purposes. However, available literature indicated that groundwater in the area has elevated fluoride levels. Little work is done on fluoride contents in the soils of the area and its implication to plants and other living organisms. Hence the objectives of this study were to determine...

Effect of soil pH on sorption of salinomycin in clay and sandy soils
Salinomycin is polyether ionophore, commonly used in poultry industry for the prevention of coccidial infections and promotion of growth. A large amount of the administered antibiotic is excreted as parent compound, eventually reaching agricultural lands. This makes it imperative for researchers to understand the behavior of the compound in soil environment by conducting sorption-desorption studies. In this...

Ecological study on Uyun Layla in Saudi Arabia
Soil characters and vegetation types have been investigated in the desiccated Uyun Layla lakes from October, 2007 till May, 2010, except during the summer months. The vegetation in and between the 23 dolines was very poor. Twenty xerophytic species were recorded mainly Zygophyllum coccineum, Zygophyllum simplex, Salsola spp., Traganum nudatum, Haloxylon salicornicum, Zilla spinosa, Rhanterium epapposum and...

Seasonal variations of physico-chemical properties of the Great Vedaranyam Swamp, Point Calimere Wildlife Sanctuary, South-east coast of India
The present study was attempted on the physico-chemical variability of the Great Vedaranyam Swamp of the Point Calimere Wildlife Sanctuary, South-east coast of India. Seasonal variation study was carried out to examine level of varying physico-chemical parameters such as temperature, salinity, pH, dissolved oxygen, nitrate, nitrite, electrical conductivity, phosphate, turbidity, total dissolved solids and...

Activity concentrations of 40K, 232Th, 226Ra and radiation exposure levels in the Tabaka soapstone quarries of the Kisii Region, Kenya
A radiological study was carried out in the soapstone quarries of Tabaka region of Kisii district in the Southern Nyanza province, Kenya, where soapstone has been mined and used as a carving medium for hundreds of years. To achieve this, 14 soil and rock samples collected from five quarries were analyzed using high-resolution gamma-ray spectroscopy. The activity concentrations of 232Th, 40K and 226Ra in the...

Identification of differentially expressed proteins in response to Pb stress in Catharanthus roseus
Lead (Pb) is a widespread nonessential heavy metal in cells and causes molecular damage to plants through the formation of reactive oxygen species (ROS) which can be alleviated by enzymatic and nonenzymatic antioxidant machinery of the plant. In the present study, proteomic studies at 3, 6, 12 and 24 days demonstrated that the effect of 150 µM Pb on Catharanthus roseus. In response to Pb, a total...

Carbon flow pattern in the forest zones of Nigeria as influenced by land use change
Forest in Nigeria plays a much wider role in the overall balance of issues affecting the country than those of climate change alone. Nigeria’s tropical forest is depleting fast, due largely to uncontrolled human activities. Poverty, urbanization, population growth and insecurity are the major causes of this trend. Tracking carbon flow in these forest life zones will help account for the effect of these...

Effect of fruiting on micronutrients, antinutrients and toxic substances in Telfairia occidentalis grown in Minna, Niger State, Nigeria
A pot experiment was conducted to determine the effect of fruiting on antinutrients (soluble and total oxalates), toxic substances (cyanide and nitrate) and some micronutrients namely: vitamin C, β-carotene (provitamin A) and mineral elements [(sodium (Na), iron (Fe), magnesium (Mg), copper (Cu), Zinc (Zn), calcium (Ca) potassium (K)] in Telfairia occidentalis grown in nitrogen...

Ecotourism and its effects on wildlife of Pachmarhi Biosphere Reserve
The present paper focused on ecotourism and its effects on wildlife. In the present scenario the ecotourism is a grooming sector in developing nations. However, its impact on wildlife and indigenous people has become a controversial issue. Pachmarhi Biosphere Reserve site explores the multitude of interactions that exist among the welfare of wildlife, conservation biology and socio-economy of the local...

Effects of magnetically treated water on water status, chlorophyll pigments and some elements content of Jojoba (Simmondsia chinensis L.) at different growth stages
In this study, the biological effects of magnetically treated water (MTW) under different water regimes (70, 50, and 30% SWHC) on water relations, photosynthetic pigments and nutrient contents of Jojoba plants has been studied under laboratory conditions. The results indicate that the magnetically treated water especially at 50 and 30% treatments has an enhancing effect on the photosynthetic pigments...

Improved ocean chlorophyll estimate from remote sensed data: The modified blending technique
Gregg and Conkright (2001) who pioneered the use of the blending technique in an attempt to calibrate ocean chlorophyll, expressed the need for further work to be done in order to obtain improved results. One problem faced when using this technique with spatially sparse data, is distortion of the resulting blended field when approaching the coastal boundaries. In this paper, the...

Creating a soil data base in a reconnaissance soil fertility study of an encroached forest reserve in Northern Nigeria for a reforestation programme
The reconnaissance soil fertility study of 10,000 ha partly encroached forest reserve located between latitude 11°47’N and 11°56’N and longitude 4°22’E and 4°32’E in Northern Nigeria was conducted in 2009 to generate a soil fertility data base of the reserve. The tracking of the forest reserve boundary was done using a Garmin 72 model global positioning system (GPS)...

Nomograms for calculating the safety factor of homogeneous earth dams in long-term stability
The slope stability analysis is routinely performed by engineers to evaluate the stability of embankment dams, road embankments, river training works, excavations and retaining walls. To ensure the geotechnical safety of the dam, the slope of embankment must be correctly designed and constructed. In this work, by applying the modified method of Bishop, an attempt was made to construct sets of nomgrams for the...
