A review on nanotechnology as a tool of change in Nigeria
Nanotechnology has generated diverse awareness and attentions nowadays and stand as one of the foremost alternative modern clean technologies of the 21st century. In spite of the essential benefits of nanoscience and technology, Nigeria is yet to key into nanotechnology initiative and strategy towards improving her socio-economic development as well as transformation of important sectors. The benefits and...

Effect of routine pathological procedure on morphometric parameters of the heart in rat models
In this study, the aim was to investigate effects of routine protocols commonly used in pathology (formalin fixation, paraffin embedding, slicing and staining) on morphometrical parameters of hearts in rats. Six males and 6 females rats were used. All of the subjects were euthanized and then hearts were fixed in formalin solution. Hearts were cut at the level of musculus papillaris and cut surfaces area were...

The driving forces of fertilizer use intensity by crops in China: A complete decomposition model
Fertilizer plays an important role in raising agricultural production in China. However, the negative environmental consequences resulting from high fertilizer use intensity have posed serious challenges to agriculture sustainability in China. The goal of this study is to identify the underlying driving forces of fertilizer use intensity by crops that help to identify challenges and opportunities and provide advices for...

The improved generalized Riccati equation mapping method and its application for solving a nonlinear partial differential equation (PDE) describing the dynamics of ionic currents along microtubules
In this paper we apply the improved Riccati equation mapping method to construct many families of exact solutions of a nonlinear partial differential equation involving parameters of a special interest in nanobiosciences and biophysics which describe a model of microtubules as nonlinear RLC transmission lines. As results, we can successfully recover the previously known results that have been found using other methods....

Genetic diversity of Quercus liaotungensis Koidz populations at different altitudes
To estimate genetic diversity and genetic structures of Q. liaotungensis at different altitudes in Xingtangsi, eight natural populations were surveyed by sequence-related amplified polymorphism (SRAP) markers. A total of 179 bands were amplified by 12 pairs of SRAP primer combinations. The average number of amplification band for each pair primers was 14.9. The percentage polymorphic band (PPB) of Q. liaotungensis was...

Synthesis of Chebyshev-I filter using folding and retiming
In synthesizing Digital signal processing (DSP) architecture, maintaining low silicon area and high performance becomes an important factor which can be achieved by various optimization techniques. To achieve this, we employ two design optimization techniques: folding and retiming, which are applied to 3rd order Chebyshev I high pass digital filter to minimize the functional units (adders, multipliers) and to reduce the...

Geometry optimization for heat sinks using thermography and finite element
Cooling systems based on Peltier cells have great advantages to be energized by renewable energy sources. This paper describes the optimization of operation of a heat exchanger which was located in the side cool on Peltier Cell. For this work, we performed infrared shots of the experiment in order to establish and analyze the pattern of heat distribution. Infrared results as well as boundary conditions fueled our...

4F_C: A conceptual framework for understanding architectural works
This paper presents a conceptual framework for understanding an architectural building by qualitatively discerning the complex issues involved in building design and systematically integrating them into a theoretical construct. The premise behind this framework is that, in design, a better understanding of what to design leads to a more informed understanding of how to design, resulting in a more structured and...
