Objective: Little knowledge is available on the antimicrobial and antioxidant properties of Coccina grandis fruits and no study has reported on its cell proliferative property. The aim of this study was to examine the antimicrobial, antioxidant and cell proliferative property of fruits of C. grandis. Material and Methods: Fruits of C. grandis were extracted using water; ethanol and acetone by c...

Tai (2005) argues for the importance of iconicity as a fundamental property of language, illustrating the modality effects of iconicity through the study of a set of iconic devices used in Taiwan Sign Language (TSL). This paper extends Tai’s research, in exploring the iconic devices used in another Asian sign language, Chinese Sign Language (CSL). Some preliminary comparisons are made in this p...

interpretation: Domains and surroundings. Abstract interpretation is a general theory for specifying and designing approximate semantics of program languages [10]. Approximation can be equivalently formulated either in terms of Galois connections or closure operators [11]. An upper closure operator ρ : C → C on a poset C (uco(C ) for short), representing concrete objects, is monotone, idempoten...

A recent framework for generalizing the Erdős-KoRado Theorem, due to Holroyd, Spencer, and Talbot, defines the Erdős-Ko-Rado property for a graph in terms of the graph’s independent sets. Since the family of all independent sets of a graph forms a simplicial complex, it is natural to further generalize the Erdős-Ko-Rado property to an arbitrary simplicial complex. An advantage of working in sim...

the principle of dimensionality reduction with pca is the representation of the dataset ‘x’in terms of eigenvectors ei ∈ rn  of its covariance matrix. the eigenvectors oriented in the direction with the maximum variance of x in rn carry the most      relevant information of x. these eigenvectors are called principal components [8]. assume that n images in a set are originally represented in mat...

Photocatalytic properties of semiconductor materials, studied now for decades, represent huge potentialities as environmentally friendly self-cleaning surfaces. Up to now, inexpensive and non-toxic TiO2-based photocatalysts remain the most interesting solution from practical industrial point view. Nevertheless, obtaining titania surface in its anatase phase, polymorph presenting best photocatal...

Maternal immune tolerance of the semiallogeneic fetus is a complex phenomenon. Macrophages are an abundant cell population in the human decidua, and changes in distribution or phenotype may be involved in the development of preeclampsia. The aim of this study was to assess the distribution and phenotype of macrophages in preterm preeclamptic, preterm control, and term control placentas. Placent...
