针对农田机井灌溉系统效率低下、管理较差的问题,提出了一种基于RFID技术的农田机井灌溉管理系统,该系统利用嵌入式微控制器LPC2103及射频芯片MF-RC522来构建,通过射频IC卡作为信息传输的媒介,以达到节水及提高效率的目的。针对传统射频IC卡易被复制,信息易被获取等问题,提出了一种新的安全认证协议,该协议确保了卡片的安全性,使该系统能够被广泛推广。实际应用表明,该系统运行良好,切实可行。

Kinetic and Pyrolysis Characteristics of Balsam Fir Needles

引用

材料科学与工程（中英文版） 2011年第5期5卷 489-503页

作者： Noorfidza Yub Harun muhammad T. afzal Faculty of Forestry and Environmental Management （FOREM） University of New Brunswick Fredericton E3B 5A3 NewBrunswick Canada

Pyrolysis of balsam fir needles was carried out to investigate the effect of both the heating rate and particle size on cellulosic component (hemicellulose, cellulose, lignin and char) yields using thermogravimetric analysis (TGA). Three sizes of particles of 150, 250 and 425 μm were prepared and each subjected to a final temperature of 800 oC at five different heating rates: 10, 20, 30, 40 and 50 oC/min. The mass change (TGA) and rate of mass change (DTG/DTA) plots and data were then analysed to obtain the pyrolysis characteristics (Vtotal, whemiceelulose, wcellulose, wlignin, wchar, wrate, max, Tmax and Tchar) and kinetic parameters (Ea, n and A). The curves exhibited five distinct degradation zones. The heating rate and particle size had a significant effect on the yield of total volatiles and char resulting from pyrolysis of balsam fir needles. The total volatiles yield was highest (68.08%) at 40 oC/min heating rate and particle size 425 μm. The activation energy and pre-exponential factors are in the range of 60 to 260 kJ/mol and 1011 to >1023. From the overall result, it is concluded that finer particle size gives out more energy for solid fuel production and coarser particle size gives out more energy for liquid fuel production.

Effects of Kinesio Taping in Supraspinatus Tendinitis

引用

Journal of Clinical and Nursing Research 2021年第6期5卷 67-71页

作者： Jawad Anwar Farjad afzal muhammad Mustafa Qamar Ayesha Basharat District Health Quarter Hospital OkaraPunjabPakistan Department of Allied Health Sciences University of SargodhaPakistan

Background:Shoulder pain is one of the most commonly reported musculoskeletal problems after low back *** common reason for the shoulder pain is supraspinatus tendinitis that is often associated with impingement ***:To find the effects of kinesio taping in reducing pain and disability in subjects with supraspinatus ***:In this study,patients were randomly allocated the treatment using a set of predefined inclusion and exclusion *** were managed with kinesio ***-and post-evaluation of the patients was done using Numerical Pain Rating Scale(NPRS)and Disability of Arm Shoulder&Hand Questionnaire(DASH)score and the data gathered was entered and analyzed using SPSS version ***:Mean difference of 2.65 was reported between the pretreatment and post treatment values of NPRS in KT taping group which was significant(P<0.05).Mean difference of 27.25 was reported between the pre-treatment and post-treatment values of DASH score in KT taping group which was significant(P<0.05).Conclusion:Kinesio taping is an effective Program in management of supraspinatus tendinitis.

Anesthetic challenges in ventilating patients with tracheal diverticulum: Case reports and review of literature

引用

World Journal of Anesthesiology 2014年第3期3卷 225-228页

作者： Mussarat afzal Ikram Chaudhary Prince muhammad Bin Abdul Aziz Hospital King Fahad Specialist Hospital

The spectrum of disorders involving the tracheobronchial tree is diverse and tracheal diverticulum is an extremely rare entity accounting for 1%-2% of cases. Tracheal diverticulum is mainly asymptomatic and discovered incidentally either on radiological examination or at autopsy. We hereby report two cases of tracheal diverticulum with hoarseness in one case and dysphagia in the second case, where intubation was difficult in both cases. However, laryngeal mask airway was inserted successfully in case one and endotracheal intubation using a smaller size intubation tube in case two.
