Dengue disease is a virus-borne illness spread by the bite of female Aedes aegypti mosquito. Jakarta Province has vulnerability to dengue due high population density and percentage urban slum households. This study applied spatial autoregressive (SAR) model identify risk factors that affect number cases in Province. The dependency was accounted for using queen contiguity weight matrix. flood-pr...
Recently, scientists are concerned about nuclear waste landfill sites. Because salt pans, salt marsh and salt domes are non-porous environment, with no stubble thickness of salt and the plant communities, less humans and animals can be found around them, so it can be used as a nuclear waste landfill. In this study, 24 environmental criteria are investigated with emphasis on hydrology, wat...
thin films of polymer doped with nonlinear optical organic dye, disperse red 1, at thickness of 1 to 2 micrometers, were prepared and studied. in order to induce an axial and orientational alignment of dye molecules within polymer matrix, a contact electric field poling was used. by this process the inherent inversion symmetry in the polymer matrix was eliminated to achieve the desired macrosco...
The classical evidence theory can result in paradox in the process of information fusion. To resolve this problem, a multi-source data fusion method based on dissimilarity matrix and evidence theory is proposed. First, using the weighted Euclidean distance, evidence dissimilarity matrix is constructed. Second, dissimilarity between the evidences is measured. Third, using dissimilarity matrix, s...
objective(s) matrix metalloproteinases comprise a family of enzyme that is able to degrade components of extra cellular matrix. there are single nucleotide polymorphisms in the promoter regions of several genes with ability to influence cancer susceptibility. the aim of this study was to analyses association between mmp2 and mmp9 promoter polymorphisms and head and neck squamous cell carcinoma ...
the purpose of the present study is to introduce the sequence space[{l_p}(e,delta) = left{ x = (x_n)_{n = 1}^infty : sum_{n = 1}^infty left| sum_{j in {e_n}} x_j - sum_{j in e_{n + 1}} x_jright| ^p < infty right},]where $e=(e_n)$ is a partition of finite subsets of the positive integers and $pge 1$. the topological properties and inclusion relations of this space are studied. moreover, the prob...
let $rin textbf{c}^{mtimes m}$ and $sin textbf{c}^{ntimes n}$ be nontrivial involution matrices; i.e., $r=r^{-1}neq pm~i$ and $s=s^{-1}neq pm~i$. an $mtimes n$ complex matrix $a$ is said to be an $(r, s)$-symmetric ($(r, s)$-skew symmetric) matrix if $ras =a$ ($ ras =-a$). the $(r, s)$-symmetric and $(r, s)$-skew symmetric matrices have a number of special properties and widely used in engi...
food safety is considered as an important world concern. the detection of pathogen and toxic materials in food has an important role in public health care. in recent years, the applications of microbial biosensor have been developed as a new approach for toxicity control. luminescent microbial biosensor is an appropriate biological tool for protection of natural environment. this type of biosen...
one of the most basic issues that currently the country and even the world is faced with the problem of lack of water and drying up of rivers, wetlands, lakes and etc. in this context, investigated for the reasons and the effects and consequences is essential. in this study, we have tried to use the swot matrix for drying river gamasyab be examined. in this regard, using the rating scale to the...
