International Journal of Clinical Medicine 2019年第10期10卷 463-468页

ntroduction: Due to widespread incidence and prevalence, human immunodeficiency virus (HIV), hepatitis B (HBV) and C (HCV), syphilis and malaria are the most common viral infections transmitted via blood transfusions. Yet there is insufficient information available about the exact prevalence of these infections among blood donors in Pakistan. The objectives of current study are to highlight the importance of blood screening among blood donors by finding the prevalence of high-risk transmissible diseases such as hepatitis B, hepatitis C, HIV, syphilis and malaria in the population of Nawabshah (Sindh) and to compare it with other provinces. Methods: A descriptive type of cross-sectional study was conducted on 37,845 blood donor volunteers at the blood bank of a tertiary care hospital, Peoples University of Medical and Health Sciences Hospital, in Nawabshah Sindh from 1st January 2018 to 31st December 2018. The data was taken from the well-maintained yearly record of the hospital blood bank. Analysis of all the data regarding blood donors was done using Statistical Program of Special Sciences (SPSS) version 20. Results: The most common age group was between 18 - 40 years. Donors were predominantly male (90%). HBV is the most prevalent disease amongst the blood donors of Peoples Medical College with a prevalence of 6.52% while HIV, HCV and malaria were 6.33%, 5.83% and 1.24% respectively whereas Syphilis is the least prevalent disease with a prevalence of 1.11%. Comparing with other provinces, the highest prevalence of hepatitis B was seen in Peoples Medical College, Nawabshah, Sindh whereas for hepatitis C it was the highest in Isra University Hospital, Hyderabad, Sindh. Moreover, Hayatabad Medical Complex in Peshawar was the least burdened with Hepatitis B (1.46%) and C (1.34%). Conclusion: Accidental diagnosis of blood-borne infections including Hepatitis B, C, HIV, Syphilis and malaria highlights importance of blood screening among the blood donors. There is a need

Frequency of Neurological Disorders and Related EEG Finding in a Tertiary Care Hospital of Karachi

引用

Journal of Biosciences and Medicines 2019年第11期7卷 56-64页

作者： Danish Mohammad Syeda Saba Zaidi Bina Fawad muhammad fazal hussain qureshi Zain Jawed Abubaker muhammad Zubair Shaikh Muzna Shah Mahira Lakhani Sara Sadiq Ziauddin University Karachi Pakistan Department of Neurology Liaquat National Hospital Karachi Pakistan Department of Community Health Sciences Ziauddin University Karachi Pakistan Department of Physiology CMH Institute of Medical Sciences Bahawalpur Pakistan

Background: Electroencephalogram (EEG) is defined as a method of detecting brain waves signifying the electrical conductivity of the brain. Globally, EEG is used to further classify neuropsychiatric disorders. Objective: To evaluate the prevalence of abnormal EEGs and related neurological disorders and it’s correlation with age and gender. Methodology: A descriptive cross sectional study was conducted in Neurology department, Ziauddin hospital, Karachi, Pakistan from June 2018 to May 2019. A total of 440 individuals based on inclusion criteria were selected through Non-probability consecutive sampling. Informed consent was obtained from study participants. A self-designed structured questionnaire and EEG record were used for data collection. Data were entered and analyzed using SPSS v 20. Mean and standard deviation was calculated for numerical variable and frequency and percentages were calculated for categorical variable. Independent t-test and chi square was used to check association of abnormal EEG with age and gender. P value of ≤0.05 was considered statistically significant. Results: The mean age of study participants was 52.98 ± 22.68 years. There were 54.5% (n = 240) males. Approximately 45.2% (n = 199) participants had predisposing condition which can lead to abnormal EEG. EEG records of 39.8% (n = 175) of the patients was normal while 60.2% (n = 265) had abnormal records. Diffuse neuronal dysfunction consistent with encephalopathy was found in 45.2%. Mild neuronal dysfunction consistent with encephalopathy accounted for 33.5% of cases. Significant difference was found in Abnormal EEG among different age group (p = 0.01). Chi square shows an association between abnormal EEG and male gender (p = 0.025). Conclusion: EEG plays a vital role in the diagnosis of neuropsychiatric conditions in developing countries. EEGs can further help to determine the relationship of different neuropsychiatric conditions and can help in early diagnosis and better prognosis.

Effect of Firing Temperature on the Electromagnetic Properties of Electronic Transformer Cores Developed by Using Nanosized Mn–Zn Ferrite Powders

引用

Acta Metallurgica Sinica(English Letters) 2015年第2期28卷 159-163页

作者： Hassan Waqas Ammad hussain qureshi muhammad Shahzad Materials Division Directorate of Technology PINSTECH

Current investigation deals with the effect of grain growth process as a function of sintering temperature on the electromagnetic properties （initial permeability, impedance, and gain） of Mn-Zn ferrite （MZF） cores （toroids）. By employing auto combustion process, nanosized [（20 ± 5） nm] MZF powders were synthesized and toroid shape cores were obtained after subsequent calcination and firing （sintering） process. It was observed that the submicron structure （0.5 μm） achieved in the ferrite core sintered at 1,000 ℃ was gradually transformed into micron size grains by increasing the firing temperature i.e., 1,100, 1,200, and 1,350 ℃. The results reveal that MZF core sintered at low temperature （1,000 ℃） showed high impedance, low initial permeability, and narrow working frequency range i.e., 3-15 MHz. However, the improvement in initial permeability, sintered density, and operational frequency range （100 kHz-17 MHz） was observed at high temperature （1,350 ℃） firing in the inert environment. This synthesized MZF core is more suitable for miniaturized switch mode power supply applications.

Ambient BackCom in beyond 5G NOMA networks: A multi-cell resource allocation framework

Digital Communications and Networks 2022年第6期8卷 1005-1013页

作者： Wali Ullah Khan Fida hussain Memon Kapal Dev muhammad Awais Javed Dinh-Thuan Do Nawab muhammad Faseeh qureshi Interdisciplinary Centre for Security Reliability and Trust(SnT)University of Luxembourg1855 Luxembourg CityLuxembourg Department of Electrical Engineering Sukkur IBA University Pakistan Department of Institute of Intelligent Systems University of JohannesburgSouth Africa Department of Electrical and Computer Engineering COMSATS University Islamabad44000IslamabadPakistan Electrical Engineering Department University of Colorado DenverDenverCO80204USA Department of Computer Education Sungkyunkwan UniversitySeoulSouth Korea

The research of Non-Orthogonal Multiple Access (NOMA) is extensively used to improve the capacity of networks beyond the fifth-generation. The recent merger of NOMA with ambient Backscatter Communication (BackCom), though opening new possibilities for massive connectivity, poses several challenges in dense wireless networks. One such challenge is the performance degradation of ambient BackCom in multi-cell NOMA networks under the effect of inter-cell interference. Driven by providing an efficient solution to the issue, this article proposes a new resource allocation framework that uses a duality theory approach. Specifically, the sum rate of the multi-cell network with backscatter tags and NOMA user equipment is maximized by formulating a joint optimization problem. To find the efficient base station transmit power and backscatter reflection coefficient in each cell, the original problem is first divided into two subproblems, and then the closed form solution is derived. A comparison with the Orthogonal Multiple Access (OMA) ambient BackCom and pure NOMA transmission has been provided. Simulation results of the proposed NOMA ambient BackCom indicate a significant improvement over the OMA ambient BackCom and pure NOMA in terms of sum-rate gains.
