There are number of images that transmitted through the web for various usages like medical imaging, satellite images, military database, broadcasting, confidential enterprise, banking, etc. Thus, it is important to protect confidentially by securing sensitive information from an intruder. The present research work proposes a Hybrid Hyper Chaotic Mapping considers a3D face Mesh model hiding sec...

BACKGROUND For patients with senile ptosis, aesthetic blepharoplasty can be combined with ptosis surgery. However, the amount of skin excision necessary in blepharoplasty is not clearly defined by measurements of the upper eyelids. OBJECTIVES The authors preoperatively evaluate the amount of skin to be excised in blepharoplasty. METHODS Fifty patients with bilateral senile ptosis were inclu...

Received April 9, 1963 We have previously reported (Heath and Ghalambor, 1963) the occurrence of 2-keto-3-deoxy-octonate @DO) as a glycosidically-bound constituent of cell wall lipopolysaccharide (LPS) of Rscherichia coli 0111-B& and the enzymatic synthesis of CMP-RDO (Ghalambor and Heath, 1963). This report presents evidence for the chemical synthesis of KDO and its enzymatic cleavage (RDO-ald...

Regeneration of the visual chromophore, 11-cis-retinal, is a crucial step in the visual cycle required to sustain vision. This cycle consists of sequential biochemical reactions that occur in photoreceptor cells and the retinal pigmented epithelium (RPE). Oxidation of 11-cis-retinol to 11-cis-retinal is accomplished by a family of enzymes termed 11-cis-retinol dehydrogenases, including RDH5 and...

Recently, reversible data hiding (RDH) techniques for JPEG images have become more extensively used to combine image and authentication information conveniently into one file. Although embedding data in JPEG image degrades visual quality and increases file size, it is proven to be useful for data communication and image authentication. In this paper, a data hiding method in JPEG image using a n...

The proline-specific X-prolyl dipeptidyl aminopeptidase (PepX; EC 3.4.14.11) and the general aminopeptidase N (PepN; EC 3.4.11.2) from Lactobacillus helveticus ATCC 12046 were produced recombinantly in E. coli BL21(DE3) via bioreactor cultivation. The maximum enzymatic activity obtained for PepX was 800 µkat(H-Ala-Pro-pNA) L(-1), which is approx. 195-fold higher than values published previously...

The present study was an attempt to investigate the acquisition of negationproperties by Persian monolingual and Kurdish-Persian bilingual learners of Englishacross different levels of language proficiency and within a generative framework.Generative models are generally concerned with issues such as universal grammar(UG), language transfer, and morphological variability in nonprimary languaged...

The genome sequence of psychrophilic Shewanella sediminis revealed the presence of five putative reductive dehalogenases (Rdhs). We found that cell extracts of pyruvate/fumarate-grown S. sediminis cells catalysed reduced methyl viologen-dependent reductive dechlorination of tetrachloroethene (PCE) to trichloroethene (TCE) at a specific activity of approximately 1 nmol TCE min(-1) (mg protein)(-...

A dechlorinating microbial enrichment culture designated TUT2264 was cultured with tetrachloroethene and then characterized for tetrachloroethene-dechlorination by culture-dependent and -independent methods. The fourth-transferred TUT2264 culture completely dechlorinated tetrachloroethene and trichloroethene, and accumulated more trans-1,2-dichloroethene than cis-1,2-dichloroethene. A real-time...

Recently, progressive interest is paid to reversible data hiding (RDH) in encrypted images, since it preserves the original cover can be recovered without any loss after embedded data is extracted to protect the confidentiality of image content’s.Earlier method used“vacate room after Encryption” in which data can be embedded by reversibly vacating room from the encrypted images. This might caus...
