An indigenous and industrially important manganese peroxidase （MnP） isolated from solid state culture of Pleurotus ostreatus IBL-02 was 2.1-fold purified and immobilized using sol-gel matrix of trimethoxysilane and proplytetramethoxysilane. Lower KM, higher Vmax, hyper-activation, enhanced acidic and thermal stability up to 70 ℃, were the improved]enhanced catalytic features of the presently sol-gel immobilized MnP. A maximum of 100% decolorization was achieved within a short time period for the different real dyes containing textile industry effluents i.e. Nishat textile （NIT）, K＆N textile （KIT）, Sitara textile （SIT）, and Crescent textile （CRT）.

Hierarchical medical diagnosis approach for COVID-19 based on picture fuzzy fairly aggregation operators

引用

International Journal of Biomathematics 2023年第2期16卷 115-151页

作者： muhammad Riaz hafiz muhammad Athar Faridt Department of Mathematics University of the Punjab LahorePakistan

In Pakistan, a hierarchical healthcare system is an efficient way of addressing the issueof limited and insufficient healthcare services. Identifying the various degrees of diseasebased on the doctor's diagnosis is an important step in developing the hierarchical healthcaretreatment structure. This research presents a framework for dealing with the issueof diagnosis values presented as "picture fuzzy numbers (PFNs)". Specifically, the goal ofthis study is to establish some innovative operational laws and "aggregation operators"(AOs) in a picture fuzzy environment. In this regard, we proposed some new neutral orfair operational laws that incorporate the concept of proportional distribution in orderto achieve a neutral or fair remedy to the positive, neutral and negative aspects ofPFNs. Based on the developed operational laws, we proposed the "picture fuzzy fairlyweighted average operator" and the "picture fuzzy fairly ordered weighted averagingoperator". Compared to previous techniques, the proposed AOs provide more generalizedand reliable. Furthermore, using proposed AOs with multiple decision-makers andpartial weight information under PFNs, a "multi-criteria decision-making" algorithmis developed. Finally, we provide an example to show how the novel approach can aidhierarchical treatment systems. This is essential for merging the healthcare capabilitiesof the general public and optimizing the medical care system's service performance.

Investigations on the Effect of Electrical Contact Degradation on High Speed Wide-Band Signal Integrity

引用

Chinese Journal of Electronics 2020年第3期29卷 525-532页

作者： WANG Ziren GAO Jinchun JI Rui BILAL hafiz muhammad Beijing Key Laboratory of Work Safety Intelligent Monitoring School of Electronic Engineering Beijing University of Posts and Telecommunications China Academy of Information and Communication Technology

Electrical contact degradation will affect the signal integrity resulting in poor communication performance. In the present work, the effect of electrical contact degradation on wide-band digital signal integrity was studied using both the theoretical analysis and experimental testing. The characteristics of digital signals with rise times of 200 ps, 400 ps, 600 ps and 800 ps through connectors with different degradation levels were *** maximum bandwidth of these signals can reach up to 1.75 GHz. An equivalent model of the connector with degraded contact surface was developed and the experimental results are consistent with the model results approximately. The influence of capacitance characteristics caused by degraded contact surface on digital signal waveform was calculated and analyzed. The results of this paper are helpful in developing a better understanding of the characteristics of wide-band digital signal waveforms through the degraded contact surface and provide a theoretical support to identify failure features in fault diagnosis.

Low temperature ferromagnetic properties of CdS and CdTe thin films

引用

Chinese Physics B 2017年第6期26卷 389-394页

作者： hafiz Tariq Masood Zahir muhammad muhammad Habib 王东明王德亮 Hefei National Laboratory for Physical Science at the Microscale University of Science and Technology of China Hefei 230026 China National Synchrotron Radiation Laboratory Center for Excellence in Nanoscience Chinese Academy of Sciences University of Science and Technology of China Hefei 230026 China

The magnetic property in a material is induced by the unpaired electrons. This can occur due to defect states which can enhance the magnetic moment and the spin polarization. In this report, CdS and CdTe thin films are grown on FTO glass substrates by chemical bath deposition and close-spaced sublimation, respectively. The magnetic properties, which are introduced from oxygen states, are found in CdS and CdTe thin films. From the hysteresis loop of magnetic moment it is revealed that CdS and CdTe thin films have different kinds of magnetic moments at different temperatures. The M–H curves indicate that from 100 K to 350 K, CdS and CdTe thin films show paramagnetism and diamagnetism, respectively.A superparamagnetic or a weakly ferromagnetic response is found at 5 K. It is also observed from ZFC/FC curves that magnetic moments decrease with temperature increasing. Spin polarized density functional calculation for spin magnetic moment is also carried out.
