Abstract This work aimed to introduce a new technique for improving sustainable biodiesel from Microchloropsis salina by examining the impact of various nitrogen sources, salt stress, and carbon enrichment, individually or in combination, determine best treatment conditions biomass lipid productivity as well quality. M. effectively utilizes nitrate (NaNO 3 KNO ) organic (especially yeast extrac...

This communication sets an evaluation framework and performs a comparative analysis of the UltraSPARC-III and the IA-64 processor architectures. It starts with an overview of a pure RISC architecture and the new EPIC technology. It then presents the unique combination of innovative features that both manufacturers claim explicit parallelism, predication and speculative loading – and the goals f...

Neurons in area MT of primate visual cortex encode the velocity of moving objects. We present a model of how MT cells aggregate responses from V1 to form such a velocity representation. Two diierent sets of units, with local receptive elds, receive inputs from motion energy lters. One set of units forms estimates of local motion, while the second set computes the utility of these estimates. Out...

A 64 X64-bit iterating multiplier, the Stanford Pipelined Iterative Multiplier (SPIM), is presented. Tbe pipelined array consists of a small tree of 4:2 adders. The 4:2 tree is better suited than a Wallace tree for a VLSI implementation because it is a more regular structure. A 4:2 carry-save accumulator at the bottom of the array is used to iteratively accumulate partial products, allowing a p...

In this paper we present a low power temporal-difference image sensor with wireless communication capability designed specifically for imaging sensor networks. The event-based image sensor features a 64 64 pixel array and can also report standard analog intensity images. An ultra-wide-band radio channel allows to transmit digital temporal difference images wirelessly to a receiver with high rat...

Recent industry developments mark a milestone in the evolution of 64-bit computing. 64-bit computing has been around for a long time in mainframe, reduced instruction set computers (RISC), and, more recently, in Intel IA-64 Itanium® architectures. Now, 64-bit computing is being standardized and driven into volume markets by AMD and Intel in processors that are based on the mainstream x86 archit...

The inhibitory effect of Ulva lactuca (Chlorophyta), Dilophus spiralis (Phaeophyta) and Jania rubens (Rhodophyta) marine algae species has been evaluated against 2 Grampositive bacterial (Streptococcus pyogenes and Micrococcus luteus); 2 Gram-negative bacterial (Shigella flexneri and Vibrio cholerae) and 2 fungal (Candida albicans and Aspergillus niger) isolates using aqueous and six organic ex...

Simple and sensitive spectrophotometric methods for the determination of midazolam (MID) are proposed. The methods are based on the bromination of the drug using N-bromosuccinimide (NBS) and the excess oxidant is determined by either malachite green (MG) or safranin O (SO), the absorbances of which are measured at 617 or 522 nm for MID-MG and MID-SO, respectively. Under the optimized experiment...

Aim We report synthesis of capped gold nanoparticles (C-AuNPs) of ≈20-30 nm by reducing HAuCl4 with flower and leaf extracts of Ocimum tenuiflorum, leaves of Azadirachta indica and Mentha spicata and peel of Citrus sinensis plants. Methods Atomic force microscopy (AFM) and transmission electron microscopy (TEM) determined their size, shape and topographical structures. The C-AuNPs with UV-Vis...
