Background: Breast cancer is the most common cancer in women both in the developed and less developed countries. Adequate information about the disease could promote early detection and prompt intervention. However, despite the various awareness campaign instituted by governmental and non-governmental bodies, its incidence continues to increase. Therefore, the study assessed the knowledge of child-bearing women in Ibadan North Local Government (IBNLG) Nigeria concerning breast cancer.

Background: Case-based learning (CBL) is being utilized in medicine, nursing, and physiotherapy educational programs as a method to improve problem solving, critical thinking, and decision making. Although the use of CBL has increased, the student characteristics that predict performance during case-based instruction have not yet been determined.

Relationships among genes, not individual alleles, are basic units of developmental information, targets of inheritance and selection. The smallest functional combination of an allele is the ratio with other alleles in a polygenic system, and amount of homo- and heterozygous relationships could determine especially the development of quantitative characters, as well as their adaptive response to natural selection, without changing the basic structure of a population. 

Indoor air pollution from burning of traditional biomass fuel such as wood, dung, and agricultural wastes for daily household cooking is a major problem in rural India. Although it is known that biomass smoke contains a wide spectrum of potentially toxic compounds, its effect on public health is relatively unexplored. In view of this, the health impact of biomass fuel use in rural India has been evaluated in this study.

Spine injuries is a serious medical condition that has a major impact on the quality of life of the patient. Although there is a varying consensus among treating physicians, surgical fixation of a traumatic fracture of the thoracic or lumbar spine is considered necessary if axial and rotational stability is severely impaired or if a neurologic deficit is present or imminent. Considerable controversy exists regarding the clinical performance of different instrumentation systems for the surgical treatment of unstable fractures of the thoracolumbar spine.

This study aimed to explore the allelopathic potential of Eucalyptus maidenii on seed germination, root and shoot length, membrane integrity, malondialdehyde (MDA) and proline content of Triticum durum, Vicia faba, Phaseolus vulgaris, Sinapis arvensis, Erica vesicaria and Scorpiurus muricatus and its application as naturally occurring herbicide in the field. Allelopathic compounds were identified using chromatography mass analysis. Dose-response studies were carried under laboratory and greenhouse conditions.

We consider the numerical solvers for discretized partial differential equations arising from different incompressible flows. We used the finite element discretization method to discretize the Navier-Stokes equations. IFISS (Incompressible Flow Iterative Solution Software) is used to obtained the different grids. We used preconditioned Krylov subspace methods to solve the resulting linear systems. Numerical experimental results are performed to compare the preconditioned iterative solvers for different types of the incompressible flows.

This work is devoted to geometrical research of the ray trajectories system. We consider trajectories of electrons moving in the second shell of an atom. The proposed model of movement of electrons is based on the geometrical interpretation of the Pauli Exclusion Principle and the geometric interpretation of distribution of electrons in energy levels, shells, and subshells of atoms in Mendeleev’s periodic table. It turned out that the second shell can be described by a cubic equation, Cardano’s formula, and a new system of triangles as well.

The elemental composition of TSP collected upon different wind sectors in the highly industrialized harbor of Dunkirk (France) were measured and the data was interpreted using a Non Negative Matrix Factorization (NMF) receptor model. Our objective was to identify the possible sources of TSP and to determine their relative contribution at the sampling site. We decided to carry out a daily sampling campaign at a fixed site and a sufficiently long period, i.e. 3 months, from February to May 2008.

The paper mentions concepts, common methods of online market research and advantages, disadvantages of each method. The author then suggests some solutions to strengthen the effectiveness of online market research application in the Library network of Vietnam National University – Ho Chi Minh City.
