TL;DR: It appeared from the trials that the quantity and quality of the blood tends to increase with size, and the highest range of the parameters was recorded in platelets, while the lowest was observed in RBC.
Abstract: Haematological characteristics of Anadara senilis was investigated. A total of two hundred and forty (240) were sampled from Andoni flats during low tide. They were immediately transferred to the laboratory, where they were sorted and grouped into four different sizes. Group one comprised of (mean length 2.54 cm ± 2.42 and mean weight of 8.37g ± 2.44); size group two has (mean length 3.84 cm ± 0.42 and mean weight 21.42) while group three has (5.76cm ± 0.38 and mean weight of 36.17g ± 3.55) and group four has mean length (7.89 cm ± 0.32; mean weight of 57.41 g ± 6.81). Blood was then taken from the bivalves and were later analysed in the laboratory. The mean values of haematological profiles recorded were (mean ± S.D), haemoglobin (Hb) 4.08 ± 1.88g dl-1; Packed Cell Volume (PCV) 10.98 ± 6.79 %; Red Blood Cells (RBC) 1.97 ± 0.68 x 1012 cells l-1; White Blood Cells (WBC) 3.76 ± 1.51 x 109 cells L-1 Platelets (PLT) 75.36 ± 88.36%; Mean Corpuscular Haemoglobin (MCH) 20.06 ± 3.98pg; Mean Corpuscular Volume (MCV) 50.64 ± 19.30Fl; Mean Corpuscular Haemoglobin (MCHC) 43.79 ± 13.71 gdl-1; Oxygen Carrying Capacity (OCC) 6.11 ± 2.83 vol. %. The highest range of the parameters was recorded in platelets, while the lowest was observed in RBC. Significant differences (P < 0.05) were observed between the four size groups in all the parameters studied. It appeared from the trials that the quantity and quality of the blood tends to increase with size. Key words: Haematology, Bloody cockle, size, Andoni flats, Niger Delta.

TL;DR: In this article, two legumes, African yam beans (Sphenostylis stenocarpa) and cowpeas (Vigna unguiculata), were processed into akara, moimoi and porridge then analyzed along with the raw samples for chemical, functional and sensory properties.
Abstract: Two legumes, African yam beans (Sphenostylis stenocarpa) and cowpeas (Vigna unguiculata), were processed into akara, moimoi and porridge then analyzed along with the raw samples for chemical, functional and sensory properties. Results showed that all the samples (raw or processed) had similar and high crude protein content with an average of 20.7%. The cowpea and African yam bean porridges had the highest (22.9%) and the lowest (19.9%) crude protein, respectively, which showed that the two legumes are very good sources of protein. Moimoi made from African yam beans had lower gelation capacity (19.4 w/v), higher water absorption capacity (68.0 ml/g), and lower oil absorption capacity (35.9 ml/g) than that made from cowpeas with 23.6 w/v, 54.0 ml/g and 41.0 ml/g, respectively. Similarly akara made from African yam beans had a higher gelation capacity of 34.5 w/v, water absorption capacity of 71.0 ml/g and a lower oil absorption capacity of 60.0 ml/g compared to that made from cowpeas (30.6 w/v, 57.0 ml/g and 62.02 ml/g respectively). Sensory evaluation showed that moimoi and akara made from African yam beans were not significantly different (p0.05) in color, flavor, texture and overall acceptability compared to those made from cowpeas indicating that African yam beans could be very useful in the preparation of moimoi and akara. In general, processing into akara and moimoi improved the oil absorption capacity of the African yam beans. The improved capacity to bind fat would be useful in ground meat formulations such as sausage in addition to the usefulness in making moimoi and akara.

TL;DR: In this paper, the authors investigated the level of replacement of fine aggregate with waste glass that will result in optimal compressive strength, flexural strength, water absorption and light weight character.
Abstract: Aggregate, both fine and coarse are major components of concrete. The cost of these aggregates is on the increase. There is also a serious environmental concern for the disposal of waste glass world-wide. These factors are major thrusts of this study- the investigation of crushed waste glass as partial replacement of fine aggregate in concrete, with a view to protecting the environment and also reducing the cost of concrete. The study investigated the level of replacement of fine aggregate with waste glass that will result in optimal compressive strength. A total of 36 cubes were cast. 6 cubes without waste glass (control) and 30 cubes containing waste glass as partial replacement for fine aggregates at 15%, 25%, 35%, 45%, and 50%. Water/cement ratio of 0.6 was used. The concrete cube samples were cured and tested at 7 and 28 days respectively for compressive and flexural strength, water absorption and light weight character. Compressive strength were found to increase by 3% and 7% at 7 and 28 days respectively as waste glass content was increased up to 15% replacement level, after which the compressive strength started to decrease. Flexural strength remained constant between the control value and 15% replacement level, after which it started to fluctuate, (decreasing by 25% and 47% at 25% replacement level at 7 and 28 days, and experienced an increase of 33% and 37.5% at 35% at replacement level. Water absorption of the concrete decreased as the waste glass content increased. Initial and final setting times decreased as the waste glass content increased, while the workability of the concrete increased as the waste glass content increased and started to experience a decrease at 35% waste glass replacement level. Key Words : compressive strength, concrete, crushed waste glass, flexural strength, setting time, water absorption and workability.

TL;DR: In this article, the potassium supplying capacity of soils formed on three geological deposits along an east-west transect in the Niger Delta region of Nigeria was investigated by determining the various forms of soil K and K uptake by repeated maize croppings in pots.

TL;DR: The failure mechanism of the river bank is complex, ranging from slip failures in high banks to shearing and toppling failures in low banks as discussed by the authors, and the use of the common slip circle model for stability evaluation appears to be adequate only for high banks.
