The speciation of some heavy metals on Typha domingensis invaded soil along Gombe road, Bauchi were evaluated. Soil samples from the Typha domengensis invaded soil and the control site were collected and analysed for exchangeable bound metals, carbonate bound metals, manganese bound metals, iron-manganese bound metals, organic/sulphide bound metals and residual bound metals. The results on the Typha domingensis invaded soil were found to be exchangeable bound metals; Fe 1.47 ± 0.21 mg/dm3, Zn 1.45 ± 0.02 mg/dm3 and Pb 0.16 ± 0.04 mg/dm3. Carbonate bound metals Fe 26.10 ± 1.01 mg/dm3, Zn 2.66 ± 0.17 mg/dm3 and Pb 0.89 ± 0.03 mg/dm3 and Manganese bound metals Fe 14.50 ± 0.45 mg/dm3, Zn 4.03 ± 0.78 mg/dm3 and Pb 1.22 ± 0.06 mg/dm3. Iron-manganese bound metals Fe 120.40 ± 19.15 mg/dm3, Zn 6.79 ± 1.12 mg/dm3 and Pb 2.16 ± 0.05 mg/dm3. Organic/sulphide bound metals Fe 5.90 ± 0.50 mg/dm3, Zn 4.14 ± 0.68 mg/dm3 and Pb 3.58 ± 0.07 mg/dm3. Residual bound metals Fe 13.10 ± 0.55 mg/dm3, Zn 6.12 ± 0.17 mg/dm3 and Pb 4.48 ± 0.09 mg/dm3.The results of the control sample (without Typha domingensis) shows that the exchangeable bound metals Fe 9.40 ± 1.89 mg/dm3, Zn 1.71 ± 0.45 mg/dm3 and Pb 0.28 ± 0.05 mg/dm3, Carbonate bound metals Fe 0.70 ± 0.12 mg/dm3, Zn 2.20 ± 0.71 mg/dm3 and Pb 0.46 ± 0.12 mg/dm3, Manganese bound metals Fe 2.50 ± 0.21 mg/dm3, Zn 1.90 ± 0.09 mg/dm3 and Pb 1.68 ± 0.04 mg/dm3, Iron-manganese bound metals Fe 221.30 ± 21.12 mg/dm3, Zn 7.46 ± 0.48 mg/dm3 and Pb 2.75 ± 0.06 mg/dm3, Organic/sulphide Fe 4.20 ± 0.62 mg/dm3, Zn 3.70 ± 0.80 mg/dm3 and Pb 3.93 ± 0.04 mg/dm3 and Residual bound metals Fe 30.10 ± 5.80 mg/dm3, Zn 7.38 ± 0.61 mg/dm3 and Pb…

“Being alive” freely roams. Roaming freedom chants spontaneous coherence. Lively coherence describes lively time. This paper shows spontaneity par excellence at joy in such time so alive. Sections of this paper show such natural coherence of time so alive, overflowing all over, to fascinatingly portray being alive in time so alive. This paper has four major sections, beginning, essential, roaming, and beginning again, plus some interesting minor ones.

Two samples of wheat flour from different source; namely, ration card system flour-supplied by Ministry of Trade- Iraq and Hilal brand flour–Turkey; were subjected for quality assessment to making flat bread, using a simple modified technique to ratify baker’s claims. Results illustrated that the Hilal flour exhibited superior characteristics indices than the ration card flour in producing total liberated, retained CO2 gas, final dough volume after 90 minutes fermentation, dough raising capacity and volume expansion ratio, although both flour were close in wet and dry gluten content %. Accordingly, the results of this test are coincident with the baker’s claims as they always praised Hilal flour and hated ration flour; meantime these results revealed to the suitability of this technique as rapid, easy and accurate in ratifying flour types for making flat bread.

We emphasized explicitly on the derivation and implementation of a new one-step numerical method for the solution of initial value problems in ordinary differential equations. In this paper, we aimed at comparing the newly developed method with other existing methods such as Euler’s method, Trapezoidal rule and Simpson’s rule. Using these methods to solve some initial value problems of first order ordinary differential equations, we discovered that the results compared favorably, which led to the conclusion that the newly derived one-step numerical method is approximately correct and can be used for any related first order ordinary differential equations.

The concept of postnatal depression might be constructed differently by people with different cultures resulting in the adoption of different coping mechanisms. Ghanaian migrant mothers living in London are no exception. The aim of this paper is to examine the perception of Ghanaian migrant mothers living in London towards postnatal depression during the postnatal period. In-depth interviews, augmented with informal conversations, were conducted with 25 Ghanaian migrant mothers who were within the postnatal period in London. Data were thematically analysed and presented. The study found that although Ghanaian migrant mothers reported experiencing stressful situations due to breastfeeding, infant temperament, lack of social support and housing problems, they were reluctant to seek help from maternal mental health services because they did not trust those health professional they encountered. Ghanaian migrant mothers appreciated the support of health visitors but the absence of family support increased their stressful situations. They, therefore, sought help when they are depressed mostly from religious leaders, friends, and distanced relatives while in London. We argue that since the Ghanaian migrant mother is a subsystem of her larger family which consist of individual elements such as the spouse or partner and her child and also relates with the wider UK environment including the health care system and the church, a change in one has an effect on all. Thus, health professionals must clarify their roles to mothers and take measures to assess migrant mothers on all aspects that influence their postnatal experiences. Identifying additional support needs of these mothers by health professionals is also paramount.

This paper examines the meaning of concept, theory and theoretical framework and their relevance in geographic studies. In particular, the paper discussed the rationale behind the formulation and application of theoretical framework in carrying out a reliable geographic study. A categorical distinction in the use of ‘concept’ and ‘theory’ interchangeably was established and it was reiterated that every science has a goal, especially in the understanding and explanation of the real world phenomena. The paper also reiterated that although geography is short on theories and long on facts, yet development of theory seems to be vital both to satisfactory explanations and to the identification of geography as an independent field of study. An empirical application of innovation diffusion theory in geographic study (collaborative web mapping – CWM) is presented. The paper concludes that, like the human body, a theoretical framework plays a central role in geographic studies because it is the skeleton on which principles, methods and overall research goals are hinged.
