New forms of vanadium oxide Nanoporous were fabricated using a simple chemical synthesis method. Vanadium pentoxide (V2O5) Nanoporous were synthesized by sodium metavanadate as precursor and ethylene glycol as surfactant. The samples were characterized by high resolution transmission electron microscopy (HRTEM), field effect scanning electron microscopy (FESEM) and X-ray diffraction (XRD), Four...

Bioerosion by Cliona delitrix and Cliona lampa was assessed at 43 sites along the Florida Reef Tract, USA, in the summer of 2001. Sponge abundances were estimated using rapid visual assessment. Tissue samples of sponges were taken for analysis of delta15N. Comparison samples were taken from Belize. Annual trends in sponge abundance were estimated from archived videos covering the period from 19...

the use of isomalt and maltitol instead of sucrose in foods has an important role in human health as controlling blood glucose levels and weight management. in this study, isomalt and maltitol instead of sucrose were used at three concentration level (75, 85, and 100%). effects of the polyols were investigated on physicochemical properties (size of bubble cake batter, moisture content, water ac...

Sponge functions were originally proposed for hashing, but find increasingly more applications in keyed constructions, such as encryption and authentication. Depending on how the key is used we see two main types of keyed sponges in practice: inner and outer -keyed. Earlier security bounds, mostly due to the well-known sponge indifferentiability result, guarantee a security level of c/2 bits wi...

Recently, smart superwetting porous materials have aroused much attention, and it is well known that tunable surface wettability pore structure/size are extremely important for their functions. However, only one factor can be regulated on existing materials, which significantly restricts controllability, functions, applications. A new material was prepared by electrodepositing a layer of polypy...

We examined the influence of depth on sponge assemblages across three lagoons at Palmyra; a remote atoll situated in the Central Pacific. The atoll is unusual in that it was heavily altered during WWII resulting in an atypical lagoon system. We conducted surveys at both 6-8m and 12-14m at 3 sites at the atoll and recorded sponge densities, area cover and available substrate for the 29 species f...

OAEP and other similar schemes proven secure in Random-Oracle Model require one or more hash functions with output size larger than those of standard hash functions. In this paper, we show that by utilizing popular Sponge constructions in OAEP framework, we can eliminate the need of such hash functions. We provide a new scheme in OAEP framework based on Sponge construction and call our scheme S...

Porous layers were produced on a p-type (100) Si wafer by electrochemical anodic etching. The morphological, nanostructural and optical features of the porous Si were investigated as functions of the etching conditions. As the wafer resistivity was increased from 0.005 to 15 Ω·cm, the etched region exhibited 'sponge', 'mountain' and 'column'-type morphologies. Among them, the sponge-type struct...

An experiment was conducted to ascertain if follicles could reach ovulatory size after the largest follicle (dominant) has been removed at different times during a progestin treatment in anestrous ewes, and secondly to determine if these new follicles could respond to an hCG-induced ovulation and have similar function as corpora lutea. Mature crossbred sheep (n=44) in anestrous were treated wit...
