Assessment of Sericin Biosorbent for Selective Dye Removal

1996第二届国际专用集成电路会议（上海）

作者： Mike W.T.Wong W.M.mak Department of Electronic Engineering Hong Kong Polytechnic University

＜正＞In order to achieve the design of state-of-the-art high-safety systems implementated in ASICs,we must incorporate totally self-checking（TSC） functional blocks, totally self-checking checkers,error-indicators and failsafe *** paper presents a design and implementation of a fault secure fail-safe multiplexer. The proposed multiplexer is constructed using a reliable fail-safe interface as basic building blocks that combines the checker function,the error-indication and the fault-tolerant output controller into one functional block.

The silk sericin is the main residue in silk production and it is found to be a low cost and efficient bio-sorbent. In this study, sericin was characterized with various techniques including SEM （scanning electron micro- scope）, XRD, N2 physisorption, FTIR （Fourier transformed infrared spectroscopy） and XPS （X-ray photoelectron spectroscopy）. The nitrogen content of sericin was ca. 8.5 mmol.g-1 according to elemental analysis. Dye adsorption by sericin biosorbent was investigated with the acid yellow （AY）, methylene blue （MB） and copper （II） phthalocyanine-3,4＇4＂4＇＂-tetrasulfonic acid （CuPc） dyes from water. Sericin displayed large capacity for AY andCuPc adsorption with adsorption capacities of respectively 3.1 and 0.35 mmol.g-1, but it did not adsorbed methyl- ene blue dye. This selectivity is due to the basicity of amide groups in seriein biosorbents.

Supplying the electronic equipment by exploiting ambient energy sources is a hot spot. In order to achieve the match between power supply and demands under the variance of environments at real time, a reconfigurable technique is taken. In this paper, a dynamic power consumption model by using a lookup table as a unit is proposed. Then, we establish a system-level task scheduling model according to the task type. Based on single instruction multiple data （SIMD） architecture which contains a processing system and a control system with a Nios II processor, a practical dynamic reconfigurable system is built. The approach is evaluated on a hardware platform. The test results show that the system can automatically adjust the power consumption in case of external energy input changing. The utilization of the system dynamic power of their portion is from 80.05% to 91.75% during the first task assignment. During the entire processing cycle, the total energy efficiency is 97.67%.

室内环境质量受到越来越多的重视。室内环境质量包括声环境、光环境、热环境和室内空气质量(IAQ)。室内空气质量(IAQ)会影响建筑物内部人群的工作效率和健康状况。开发了一种计算流体力学(CFD)软件,并用来模拟了几种典型的室内空调系统中的气体流动。这些算例能够用来改进和优化空调系统部件的设计。CFD软件模拟算例的结果图显示了流动的压力分布和速度场。采用有限体积法Ni格式求解N.S方程,并为更好地模拟粘性流动,使用了k-ε湍流模型。

Melanocytic lesions of the CNS are rare tumours originating from melanocytes that are present in the leptomeninges. They consist of a spectrum of pigmented tumours ranging from melanocytoma to melanoma. A small group of these tumours have histopathological features between those of a benign melanocytoma and a malignant melanoma;these present as intermediate grade melanocytic neoplasms. Naevus of Ota is a blue hyperpigmented dermal lesion characterized by increased number of melanocytes in the distribution of ophthalmic and maxillary divisions of the trigeminal nerve. The association of an intracranial intermediate-grade melanocytic neoplasm with a nevus of Ota is extremely rare, with only 2 cases reported in the literature to date. As a result, their behavior and progression are still poorly understood. We present the first case of a familial naevus of Ota associated with intermediate-grade melanocytic neoplasm.
