A Critical Review on the Book Hussain Ibn Musa (AS), His Life, Personality, Sepulcher
No full textHussain ibn Musa ibn Jafar is a famous Alawi person who transmitted some Hadiths from his father Imam Musa al Kazim and his brother, Imam Ali ibn Musa al Rida (A.S). This lofty position and proximity to the Imamate line, caused the construction of some attributed Sepulchers to him in many cities, of which Tabas, located in the east of Iran, has more fame. Ali Akhavan Mahdavi has written a book on this important personality, his life, and his real place of burring. The present study aims to examine the book critically, therefore, tries to introduce and examine the book, then discusses some problems in it and presents suggestions regarding both the form and the content. So, we prepare our study with the use of a descriptive-analytical approach and of course a special usage of the main historical sources to which compare the contents of them. In conclusion, the author reached some important innovations in comparison with similar sources and studies, and it is completely clear by analyzing the content of hadith and genealogy books. Examination of the Akhavan Mahdavi's book showed that although this book has many advantages and has been effective on subsequent works written on this subject, but shortcomings such as lack of research background and critique of sources, the author's little use of Hadith and Rijal sources are among the cons. Some of the author's citations have diminished the book's credibility
Result of management of closed distal radial fracture by Ayjaz Azim foundation mini external fixator
No full textBackground: Distal radius fractures are one of the most common orthopedic conditions and intra-articular types (AO/ASIF type C) are difficult to treat. While various treatment options exist, external fixation remains valuable, particularly in the developing world. The present study evaluated the efficacy of the Ayjaz Azim foundation (AAF) mini external fixator for the treatment of closed, complete articular distal radius fractures.
Methods: This study evaluated outcomes in 32 patients with closed intra-articular distal radial fractures by purposive sampling. Patients between 18 and 60 years, within two weeks of injury, received standardized surgery. Structured questionnaires were used to collect data, and outcomes at 12 weeks after surgery were assessed using Sarmiento's radiological criteria and the Green and O'Brien functional scoring system. Statistical analysis was performed with SPSS v26, and significance was at p<0.05.
Results: The study population (41.63±12.39 years) had a predominance of males (78.1%), and the most common injury mechanism was motor vehicle accidents (68.75%). Surgery was performed in 90.6% of patients within 24 hours of trauma. Radiologically, 62.5% had excellent results, 31.3% good, and 6.3% fair. The mean loss of volar tilt was 5.03°±3.84°, radial shortening 2.47 mm±2.27 mm, and radial inclination 4.03°±3.27°. Functionally, 62.5% had excellent results, 21.9% good, 12.5% fair, and 3.1% poor. Pin tract infection occurred in 16% of the cases and post-removal stiffness in 62.5% of patients. Radiological and functional results had a good correlation (r=0.876, p<0.001).
Conclusions: AAF mini external fixator is a useful tool for the treatment of AO/ASIF type C distal radius fractures, with 94% patients showing satisfactory results. The technique is reliable for anatomical reconstruction and functional rehabilitation with acceptable complication rates and is a well-suited treatment method worthy of consideration, particularly in regions with limited resources

The use of RFID technology to measure the compositions of diethyl ether-oil-brine mixtures in enhanced imbibition experiments
No full textRecent developments in Radio Frequency (800 MHz–1000 MHz) Identification (RFID) devices suggest that it is possible to use them for wireless laboratory measurements of the dielectric coefficients (or compositions) of fluid mixtures with possible spin-off for their use in the petroleum engineering practice. The advantage of RFID devices is their small size (0.095×0.008×0.001 m3), the developments to make them increasingly smaller and that they do not require the use of leak prone connecting cables. RFID measures the response of a sample volume of interest irradiated by a radio frequency electromagnetic (EM) wave. The response can be expressed in terms of various response functions, e.g. two scattering functions (S11 and S21) or the minimum irradiated power (Pmin). The response functions can be measured using a state-of-the-art RFID device (CISC RFID Xplorer-200), which operates in the range between 800 and 1000 MHz. The effect of the dielectric coefficient on the RFID response was tested by placing the RFID tag in different media with various dielectric coefficients ε ranging from 1 to 80. The overall purpose is to develop a work-flow to relate the response functions obtained with RFID technology to the dielectric coefficient and thus the composition of fluid mixtures in which an RFID tag can be immersed. An application is to measure fluid compositions during a spontaneous imbibition experiment in an Amott-cell. As an intermediate step we measure the composition dependence of the partial molar volume of diethyl ether (DEE) in brine and the partial molar volume of DEE in oil by using an Anton Paar density meter. The relation between the dielectric coefficients and the volume fraction can be obtained with the Böttcher mixing rule. The DEE volume fraction range of interest is 0–8% volume fraction in the aqueous solution whereas DEE volume fraction range of interest is 0–100% volume fraction in oleic solutions. For better understanding of the measurement results, we used COMSOL™ simulations, which show that the response functions depend on the dielectric coefficient in a vessel of appropriate dimensions filled with a fluid of choice. The measurements show that the minimum power at the tag position Pmin is the preferred response function and that the sensitivity of Pmin was highest at 915 and 868 MHz for aqueous (8.547×10−6) and oleic (1.905×10−4) solutions respectively. The measurement error is of the same order of magnitude as the errors mentioned above (Hon, 1989) ensuing from evaporation of DEE during the preparation of the calibration fluids or the approximate nature of the Böttcher mixing rule. We conclude that it is possible to use RFID technology for contact-less measurements of the compositions of fluids in imbibition experiments.Reservoir Engineerin
Adapting multilingual vision language transformers for low-resource Urdu optical character recognition (OCR)
No full textIn the realm of digitizing written content, the challenges posed by low-resource languages are noteworthy. These languages, often lacking in comprehensive linguistic resources, require specialized attention to develop robust systems for accurate optical character recognition (OCR). This article addresses the significance of focusing on such languages and introduces ViLanOCR, an innovative bilingual OCR system tailored for Urdu and English. Unlike existing systems, which struggle with the intricacies of low-resource languages, ViLanOCR leverages advanced multilingual transformer-based language models to achieve superior performances. The proposed approach is evaluated using the character error rate (CER) metric and achieves state-of-the-art results on the Urdu UHWR dataset, with a CER of 1.1%. The experimental results demonstrate the effectiveness of the proposed approach, surpassing state of the-art baselines in Urdu handwriting digitization

Traversing the Waste Spectrum: Unveiling Pakistan\u27s MSW Landscape and Solutions
No full textMunicipal solid waste (MSW) management must be sustainable in order to meet the Sustainable Development Goals (SDGs) and address health, environmental, and disposal challenges caused by the vast amounts of trash generated. MSW management going wrong puts locals in danger. In Pakistan, the production of municipal solid trash is rising daily. Urban settlers and other organizations gather a lot of waste in various forms, usually defiling and making our surroundings uninviting. Due to the indiscriminate dumping of various wastes, the soil quality in the metropolitan area has decreased as a result of solid and liquefied waste disposal. Significant environmental concerns regarding soil and water pollution arise from transferring contaminated garbage and mixed fluid outside of waste disposal borders. The impacts of municipal garbage disposal on soil and water quality at open waste dumping sites were the main focus of this review. Using a soil and water quality index, in many regions of the world especially in regions where waste management practices are insufficient, the contamination of soil and water owing to incorrect municipal solid waste disposal is a serious environmental hazard. Open dumping, unregulated landfilling, and illegal dumping are examples of improper waste disposal practices that can result in pollution that affects the quality of the soil and water. They must also seek to identify sustainable waste management solutions. The effect of these emitted gaseous emissions has, however, been thoroughly researched. To safeguard the environment and public health, quick action must be made to control trace element pollution
Factors associated with low back pain in adult: a study in a tertiary care hospital of Bangladesh
No full textBackground: Low back pain (LBP) is a very common health problem in humans that may cause disability and can affect work performance and well-being. It can be acute, subacute, or chronic in condition. Although several risk factors of LBP have already been identified like occupational posture, age, depressive moods, body height, or obesity we have not enough research-based data regarding this issue.
Aim of the study: The aim of this study was to evaluate the risk factors associated with low back pain in adults.
Methods: This cross-sectional observational study was conducted in the Department of Physical Medicine & Rehabilitation, Shaheed Ziaur Rahman Medical College Hospital, Bogura, Bangladesh during the period from July 2019 to December 2020. In total 57 confirmed LBP patients were enrolled as the case group patients and 30 healthy people were included as the control group participants in this study. All the clinical data regarding LBP were collected by using a predesigned questioner. Data were processed analyzed and disseminated by MS Office and SPSS programs as per need.
Results: In analyzing the risk factors of low back pain among the participants we observed, 47% of case group participants were used to remain in a sitting position for 0-1 hours per day whereas it was found among 67% in the control group. Moreover, in the case group, 14% of participants used to remain in a sitting position for more than 6 hours per day which was only 7% in the control group. Besides age (p=0.004) among several possible risk factors, in this study, we found a significant correlation of low back pain in the duration of sitting position between the case and control groups, where the p-value was 0.006.
Conclusion: Continuation of a long time sitting position is a harmful thing for the human musculoskeletal system. Now a day the lifestyle factors should be assessed with more attention for detecting the basic etiology of low back pain
