American Journal of Food Technology , 2008,
Abstract: A study was conducted to determine the response of broiler starter and finisher chicks to dietary levels of Lablab purpureus beans processed by boiling in water for 30 min at 100 °C. For both the starter and the finisher phases, seven isonitrogenous diets containing 23.78% crude protein for the starter and 20.91% crude protein for the finisher were formulated to contain lablab seed meal at 0.0, 5.0, 10.0, 15.0, 20.0, 25.0 and 30.0% levels respectively. Diet 1, in each phase had no lablab and served as the control. Each dietary treatment for the starter and the finisher phases was replicated three times in a completely randomized design. There were 25 birds per replicate. Feed and water were given ad libitum. The experiment lasted from 0 to 4 weeks for the starter phase and from 5 to 8 weeks for the finisher phase. Results obtained for the starter phase shows significant (p<0.05) depression in final weight, weight gain, feed intake, feed efficiency and feed-gain ratio. These parameters decreased as the level of lablab seeds in the diets increased. However, feed cost (/kg feed and /bird) were significantly (p<0.05) reduced as the level of lablab seed meal increased in the starter diets. The results obtained for the finisher phase also showed a similar trend. While there were significant (p<0.05) decreases in final weight, weight gain, feed intake and feed efficiency as the level of lablab seed meal increased in the diets, feed cost (/kg feed and /bird) were significantly (p<0.05) lowered. Parameters measured for carcass analysis such as live weight and weights of the breast, thigh, wing, neck, legs and head showed a significant (p<0.05) decrease as the dietary levels of lablab seed meal increased. The PCV, Hb and the TP status of the blood indicated significant (p<0.05) decreases as the levels of lablab in the diets increased. However, Lablab purpureus beans can be included up to 5% level in broiler starter and up to 10% level in broiler finisher diets without any adverse effect on the performance of the birds.

Pakistan Journal of Biological Sciences , 2007,
Abstract: : The lablab seeds were cooked for 30 min, sundried for three days and thereafter milled and incorporated into chickens’ diets. Six treatments, comprising of six dietary levels of lablab at 0.0, 7.5, 15.0, 22.5, 30.0 and 37.5%, respectively was fed during the grower’ s phase. Results obtained for the growers phase indicate that final weight (g/bird), weight gain (g/bird) and feed cost (N kg- 1) decreased significantly (p<0.05) as the level of lablab increased in the diet. Feed intake (g/bird and g/bird/day) as well as feed cost (N/bird) and total cost (N/bird) also decreased significantly (p<0.05) as the level of lablab increased in the diet up to 22.5% inclusion level before increasing as the level of lablab in the diets continued to increase. The level of lablab in the diet had no effect on mortality throughout the experimental period. In addition haematological parameters such as Packed Cell Volume (PCV), Haemoglobin (Hb) and Total Protein (TP) were not significantly (p<0.05) affected by feeding diets containing graded levels of cooked lablab beans to pullets. Results obtained during the laying phase indicates that feeding lablab seed meal up to 22.5% in the diets at the growers stage had no significant adverse effect (p<0.05) on final weight, feed intake, feed efficiency, percent henday and henhoused egg production, percent production at peak, kilogramme feed per twelve eggs, feed cost per twelve eggs, Haugh Unit and yolk index. However, age of birds at first egg, age at 50% production and age at peak egg production were increased significantly (p>0.05) with increase in the level of lablab seed meal in the growers diets.

Journal of Biological Sciences , 2007,
Abstract: The effect of duration of cooking of Lablab purpureus beans on the performance, organ weight and haematological parameters of Shika-brown pullet chicks from 0-8 weeks was investigated. Eight dietary treatments of which seven in which Lablab purpureus beans cooked for 0, 10, 20, 30, 40, 50 and 60 min) was included and a control (Corn-Soyacake-Groundnut-cake based diet) were formulated. These were replicated three times with 25 birds per replicate in a complete randomized design. The birds were managed under the deep litter system. Results obtained showed that cooking time had significant (p< 0.05) improvement on performance characteristics such as final weight, weight gain, feed conversion efficiency and percent mortality. Organ weights such as the liver, the heart and the pancreas decreased as the duration of cooking increased while haematological parameters such as the Total Protein (TP) the Packed Cell Volume (PCV) and the Haemoglobin (Hb) increased slightly, (although not significantly) in the blood up to about 30 min of cooking before decreasing as the duration of cooking continued to increase. These observations are indications that higher durations of cooking up to about 30 min render the nutrients in the raw lablab seeds more available for utilization by the birds.

Pakistan Journal of Biological Sciences , 2013,
Abstract: A total of 270 broiler chickens were used for the study. The birds were fed common diet containing 23% Crude protein and 2864 kcal kg-1 Metabolizable energy at the starter phase while 20% Crude protein and 2923 kcal kg-1 Metabolizable energy was fed at the finisher phase. Starter and finisher diets contained 10 and 15% inclusion levels of rice offal respectively. Granite grit was added to the basal diet at 0.0, 2.0, 4.0, 6.0, 8.0 and 10.0 g per bird per month thus making a total of six treatments. Each treatment was replicated three times with 15 birds per replicate in a completely randomized design. Packed cell volume and haemoglobin level were not significantly (p>0.05) affected by dietary grit levels while total protein increased across the graded levels of granite grit. Crude protein, crude fibre and nitrogen free extract significantly (p<0.05) improved with increasing grit levels. These parameters improved up to the highest level of grit addition (10.0 g) granite-grit. It was concluded that 10.0 g granite grit per bird per month is beneficial to broiler chickens as it allows for efficient nutrient utilization. Further study to determine the optimum level of granite grit in broiler diet is encouraged since result obtained showed the optimum level was not attained.

Environment and Natural Resources Research (ENRR) , 2012, DOI: 10.5539/enrr.v2n2p48
Abstract: Fluctuation in plankton abundance and diversity of the Imo River in Etche, a Niger Delta region of Nigeria was investigated. Plankton samples were collected with 55 micro meter mesh size plankton net at 7 sampling locations once monthly between March 2007 and February 2009. Samples were preserved with 4% formalin solution in labeled plastic containers in the field. In the laboratory, 1ml of the plankton subsample was withdrawn with a wide-mouthed pipette from field samples and placed on a Sedge-wick rafter-counting chamber for species identification and counts with standard keys through direct microscopy. The studentized t-test of significance was used to partition numerical abundances of plankton biotypes seasonally. Phytoplankton comprised 43 genera and a mean density of 1859 cells/ml. The dominant phytoplankton was the Bacillariophyceae (53.25%), followed in order by Cyanophyceae (21.25%), Chlorophyceae (10.33%), Chrysophyceae (4.84%), Pyrrophyceae (4.57%), Xanthophyceae (3.39%) and Euglenophyceae (2.42%). Zooplankton was made up of 7 taxa and a mean density of 433 organisms/ml. The order of dominance was the Cladocera (25.87%), Copepoda (20.55%), Protozoans (19.17%), Rotifera (18.71%), fish eggs and larvae (9.24%), Crab larvae (4.62%), and Beetle larvae (0.69%). Phytoplankton species showed oscillating as well as stable seasonal patterns of occurrence. Higher Margalef’s diversities were recorded in the dry (3.655; 57% and 1.273; 61%) than wet season (2.732; 43% and 0.810; 39%) for phytoplankton and zooplankton biotypes, respectively. Phyto- and zoo-plankton taxa each showed significant numerical differences between the 2007/2008 and 2008/2009 sampling periods [F(14.39)>Fcrit(4.30) and F(29.08)>Fcrit(4.23), respectively] at P<0.05. The observed seasonal peaking in abundance could be attributed to periods of concentrations of nutrients and stability in growth factors of plankton biotypes.

International Journal of Biosciences , 2011,
Abstract: Dynamics in spatial yields of primary production in the middle course of the Imo River in Etche, South-eastern Nigeria has been investigated. At seven sampling locations along the course of the river, in situ measurements for water temperature, pH, turbidity, and dissolved oxygen (DO) were made with HORIBA U-10 Water Quality Checker. The light and dark bottle technique was used to measure primary production. Wide variations were observed in turbidity (11.0-279.0, mean = 96.7 ± 9.3 NTU), DO (4.50-8.81, mean = 6.96 ± 0.14mg/l), and sulphate (0.90-8.10, mean = 4.35 ± 0.25mg/l) across the sampling locations. Gross and net primary production (GPP & NPP) as well as community respiration (CR) ranged from 0.10-11.2 (0.9 ± 0.2), 0.1-1.0 (0.4 ± 0.03), and 0.02-0.5 (0.2 ± 0.02) mgO2l-1d-1, respectively. Sampling location 1 showed the highest GPP, NPP, and CR of 0.9, 0.6, and 0.3 mgO2l-1d-1, respectively while location 7 showed the least GPP of 0.6 mgO2l-1d-1, and locations 2-7 the least CR of 0.2mgO2l-1d-1each. At P<0.01, GPP correlated negatively with turbidity (r=-0.322) and sulphate (r=-0.297), NPP correlated negatively with turbidity (r=-0.592), nitrate (r=-0.435), phosphate (r=-0.365), and sulphate (r=-0.594) and CR correlated negatively with turbidity (r=-0.547), nitrate (r=-0.405), phosphate (r=-0.304), and sulphate (r=-0.551). Marked variance in means of primary production attributes at P<0.05 was mostly observed in sampling locations 1 and 4.The observed oligotrophic production of the river was most probably due to low nutrient levels and high turbidity, which blankets off sunlight necessary for photosynthesis.

Abstract: Network theory and its associated techniques has tremendous impact in various discipline and research, from computer, engineering, architecture, humanities, social science to system biology. However in recent years epidemiology can be said to utilizes these potentials of network theory more than any other discipline. Graph which has been considered as the processor in network theory has a close relationship with epidemiology that dated as far back as early 1900 [1]. This is because the earliest models of infectious disease transfer were in a form of compartment which defines a graph even though adequate knowledge of mathematical computation and mechanistic behavior is scarce. This paper introduces a new type of disease propagation on network utilizing the potentials of neutrosophic algebraic group structures and graph theory.

Natural Science (NS) , 2010, DOI: 10.4236/ns.2010.22013
Abstract: A comparative research has been developed for acidity and stability constants of M(Glu)1, M(Asp)2 and M(Ttr)3 complexes, which have been determined by potentiometric pH titration. Depending on metal ion-binding properties, vital differences in building complex were observed. The present study indicates that in M(Ttr) com-plexes, metal ions are arranged to the carboxyl groups, but in M(Glu) and M(Asp), some metal ions are able to build chelate over amine groups. The results mentioned-above demonstrate that for some M(Glu) and M(Asp) complexes, the stability constants are also largely determined by the affinity of metal ions for amine group. This leads to a kind of selectivity of metal ions, and transfers them through building complexes accompanied with glutamate and aspartate. For heavy metal ions, this building complex helps the absorption and filtration of the blood plasma, and consequently, the excursion of heavy metal ions takes place. This is an important method in micro-dialysis. In this study the different as-pects of stabilization of metal ion complexes regarding to Irving-Williams sequence have been investigated.

Open Journal of Geology (OJG) , 2013, DOI: 10.4236/ojg.2013.32B004

This study was carried out in Harat Rahat (south of Almadinah Almonwarah) using seismic reflection and resistivity methods. The main objectives of this study are to determine the extent of the basaltic layer and to define the subsurface faults and fractures that could affect and control the groundwater movement in the study area. A 2D seismic profile was acquired and the result shows that the subsurface in the study area has a major fault. We obtained a well match when the seismic result was compared with drilled wells. As a complementary tool, the resistivity method was applied in order to detect the groundwater level. The results of the resistivity method showed that six distinct layers have been identified. The interpretation of these six layers show that the first three layers, the fourth layer, the fifth layer and the bottom of the section indicated various subsurface structures and lithologies; various basaltic layers, fractured basalt, weathered basement and fresh basaltic layers, respectively. It is obvious that the eventual success of geophysical surveys depend on the combination with other subsurface data sources in order to produce accurate maps.
