The sublethal toxic potency of malathion in inhibiting acetylcholinesterase activity of brain, muscle, gill and liver tissues of the fish,Tilapia mossambica was studied at 12 h intervals. Maximum in hibition at 36 and 48 h, and complete revival of acetylcholinesterase activity after 72 h was noticed, suggestive of the loss of inhibition of the enzyme(More)
Built-in self-repair (BISR) technique has been widely used to repair embedded random access memories (RAMs). This paper presents a reconfigurable BISR (ReBISR) scheme for repairing RAMs with different sizes and redundancy organizations. An efficient redundancy analysis algorithm is proposed to allocate redundancies of defective RAMs. In the ReBISR, a(More)
The development of green, selective, and efficient catalysts, which can aerobically oxidize a variety of alcohols to their corresponding aldehydes and ketones, is of both economic and environmental significance. We report here the synthesis of a novel aerobic oxidation catalyst, a zeolite-confined nanometer-sized RuO(2) (RuO(2)-FAU), by a one-step(More)
We report a novel post-loading approach for constructing a multifunctional biodegradable polyacrylamide (PAA) nanoplatform for tumor-imaging (fluorescence) and photodynamic therapy (PDT). This approach provides an opportunity to post-load the imaging and therapeutic agents at desired concentrations. Among the PAA nanoparticles, a formulation containing the(More)
Embedded computer systems are systems in which one or more computers monitor and control a larger electromechanical system. Applications include telecommunication systems, health care systems, defense systems, manufacturing automation systems, etc. Many of these systems have mission-critical requirements and, hence, it is necessary to have high confidence(More)
Discrete cosine transform (DCT) is usually used in JPEG based image transform coding. This paper presents separable 2-D discrete Hartley transform (SDHT) and its Distributed Arithmetic (DA) based hardware architecture as an alternate to DCT in transform based coding of image compression. The proposed DA architecture for 1-D DHT has very less computations as(More)
