BACKGROUND Early Childhood Caries (ECC) is defined as the presence of caries lesion in an primary tooth in children below the age of 71 months. It is a significant public health problem with consequences for the growth and development of affected children. The objective of this study was to determine the prevalence and ECC risk indicators in a suburban population in Nigeria. METHODS The data ...

OBJECTIVES Early childhood caries (ECC) has several risk factors and it is important stressful/painful events of childhood and immunosuppression may occur during this unique rampant caries pattern. The changes in the host immune competence by compromised cellular immune system functions can activate Epstein Barr virus (EBV). The objective of this study was to determine whether the supragingival...

An extrusion process especially designed for extrusion of pipes made from fiber reinforced cementitious materials has been developed at Department of Structural Engineering and Materials at the Technical University of Denmark. Engineered Cementitious Composite (ECC) materials have been developed in recent years at Department of Civil and Envirionmental Engineering, University of Michigan. These...

Cryptography is used to transmit the data securely in open network. This paper gives the survey of Elliptic Curve Cryptosystem (ECC) used in many applications. ECC is a when compared to RSA and discrete logarithm systems, is a better option for the future. For this reason ECC is such an excellent choice for doing asymmetric cryptography in portable devices right now. The smaller ECC keys it tur...

In this paper, a research study is presented focusing on the effect of substituting brittle concrete in conventional reinforced concrete column members with a ductile engineered cementitious composite (ECC). Based on the material properties of ECC, the interaction with structural reinforcement is characterized by compatible deformations of the reinforcement and ECC matrix in the elastic and ine...

Synopsis: Cementitious materials are generally classified as semi-conductors that are capable of carrying electricity when an external electrical signal is applied. The electrical properties of cementitious materials have been widely explored for monitoring their internal hydration processes. However, comparatively less work has been done in using the inherent electrical properties of cementiti...

BACKGROUND This survey was intended to investigate prevalence and severity of early childhood caries (ECC) in a sample of children in Southern Italy and to identify factors that may be related to this condition. METHODS The study was designed as a cross-sectional survey. The study population (children aged 36-71 months) attending thirteen kindergartens was randomly selected through a two-stag...

The paper presents a solution for endcoding/decoding access to the subway public transportation systems. First part of the paper is dedicated through section one and two to the most used 2D barcodes used in the market – QR and DataMatrix. The sample for DataMatrix is author propietary and the QR sample is from the QR standard [2]. The section three presents MMS and Digital Rights Management top...

ـ ـــ Finding multiplicative inverse (Modular Inversion) operation is the most time-consuming operation in Elliptic Curve Crypto-system (ECC) operations which affects the performance of ECC. Moreover, several factors that affect the design of ECC have not been intensively investigated in the majority of researches related to ECC, Such as system utilization, area, resources-consuming and area*ti...
