Quality of life among women living in Haor Basin in Bangladesh and its socio-economic predictors

The Haor region in Bangladesh is a relatively more poverty-driven area than other rural areas of Bangladesh. There is very little information about the quality of life of women living in Haor areas. Therefore, the present study aimed to assess Haor women's quality of life and identify predictors. The data from the project titled ‘Livelihood and Socio-economic well-being of Women Living in Haor Basin: A Cross-sectional Survey’ were utilized in this study. Results showed that household income was lower than that reported in the household income and expenditure survey or HIES Survey 2016 for rural people in Bangladesh. Around half of them actively participated in the household economic decision-making process and one- fifth were satisfied with their household and personal financial condition. Only 30% rated their quality of life as good or very good. Contribution to household income, importance and control over household economic decisions, and household savings and loans, were significantly associated with the overall quality of life and its domains. This study’s findings would help to design and implement policies and development program to improve the living standard of women living in Haor Basin and thus help to achieve the relevant targets under specific sustainable development goals

Implementation of the Trigonometric LMS Algorithm using Original Cordic Rotation

The LMS algorithm is one of the most successful adaptive filtering algorithms. It uses the instantaneous value of the square of the error signal as an estimate of the mean-square error (MSE). The LMS algorithm changes (adapts) the filter tap weights so that the error signal is minimized in the mean square sense. In Trigonometric LMS (TLMS) and Hyperbolic LMS (HLMS), two new versions of LMS algorithms, same formulations are performed as in the LMS algorithm with the exception that filter tap weights are now expressed using trigonometric and hyperbolic formulations, in cases for TLMS and HLMS respectively. Hence appears the CORDIC algorithm as it can efficiently perform trigonometric, hyperbolic, linear and logarithmic functions. While hardware-efficient algorithms often exist, the dominance of the software systems has kept those algorithms out of the spotlight. Among these hardware- efficient algorithms, CORDIC is an iterative solution for trigonometric and other transcendental functions. Former researches worked on CORDIC algorithm to observe the convergence behavior of Trigonometric LMS (TLMS) algorithm and obtained a satisfactory result in the context of convergence performance of TLMS algorithm. But revious researches directly used the CORDIC block output in their simulation ignoring the internal step-by-step rotations of the CORDIC processor. This gives rise to a need for verification of the convergence performance of the TLMS algorithm to investigate if it actually performs satisfactorily if implemented with step-by-step CORDIC rotation. This research work has done this job. It focuses on the internal operations of the CORDIC hardware, implements the Trigonometric LMS (TLMS) and Hyperbolic LMS (HLMS) algorithms using actual CORDIC rotations. The obtained simulation results are highly satisfactory and also it shows that convergence behavior of HLMS is much better than TLMS.Comment: 12 pages, 5 figures, 1 table.

Pseudo Random Binary Sequence Based on Cyclic Difference Set

With the increasing reliance on technology, it has become crucial to secure every aspect of online information where pseudo random binary sequences (PRBS) can play an important role in today's world of Internet. PRBS work in the fundamental mathematics behind the security of different protocols and cryptographic applications. This paper proposes a new PRBS namely MK (Mamun, Kumu) sequence for security applications. Proposed sequence is generated by primitive polynomial, cyclic difference set in elements of the field and binarized by quadratic residue (QR) and quadratic nonresidue (QNR). Introduction of cyclic difference set makes a special contribution to randomness of proposed sequence while QR/QNR-based binarization ensures uniformity of zeros and ones in sequence. Besides, proposed sequence has maximum cycle length and high linear complexity which are required properties for sequences to be used in security applications. Several experiments are conducted to verify randomness and results are presented in support of robustness of the proposed MK sequence. The randomness of proposed sequence is evaluated by popular statistical test suite, i.e., NIST STS 800-22 package. The test results confirmed that the proposed sequence is not affected by approximations of any kind and successfully passed all statistical tests defined in NIST STS 800-22 suite. Finally, the efficiency of proposed MK sequence is verified by comparing with some popular sequences in terms of uniformity in bit pattern distribution and linear complexity for sequences of different length. The experimental results validate that the proposed sequence has superior cryptographic properties than existing ones

Islamic Articulation of the Carpe Diem Motif in Herrick\u27s "To Daffodils": A Post-Structuralist and Intertextual Inquiry

While Herrick is known for his religious poetry, the intersection of Islam and his work has not been explored in existing literature. The article examines the potential for Islamic meanings within Robert Herrick\u27s poem "To Daffodils" through post-structuralist and intertextual lenses of literary analysis. The study employs the tenets of post-structuralism to explore the poem\u27s thematic significance in relation to Islam. The analysis takes into account the temporal context of Herrick\u27s 17th century era and the emergence of secularism, as well as the notion of the universality of Islam. The study concludes that the poem serves as a powerful reminder of the transient nature of human life, which is also a central theme in Islamic ethos. Herrick\u27s work can be seen as an exemplar of Islamic knowledge, which imparts messages to humans about the temporality of life and its purposes and its eventual end. This article highlights the importance of Islamic reading of Herrick’s literature conveying important messages about the human condition and the significance of contemplating the ephemeral nature of life

The outcome of third stage of labor using carbetocin following vaginal delivery

Background: Primary postpartum hemorrhage (PPH) is a major cause of morbidity and the leading cause of direct maternal death worldwide. Carbetocin, a synthetic analog of oxytocin, has an elimination half-life of 40 minutes compared with 10 minutes for oxytocin, Methods: This cross-section observational study was conducted at the department of obstetrics and gynaecology, Shaheed Suhrawardy medical college hospital, Dhaka, Bangladesh. The study period was from May 2016 to October 2016. 100 women undergoing normal vaginal delivery were the study subject. A convenient sampling technique was used in this study. Necessary data was collected in the data collection sheet. A standardized deliver mat (Quaiyum's mat) was used before placental removal for measuring blood loss. Carbetocin was an intervention in this study. Statistical analysis was carried out by using the statistical package for social sciences version 19.0 for Windows (SPSS Inc., Chicago, Illinois, USA). The mean values were calculated by frequencies and percentages. Result: In this study, the majority 54 (54.0%) of patients belonged to age 20-25 years, followed by 30, (30.0%) >25 years. Regarding the occupational status of the patients, it was observed that the majority of 92 (92.0%) patients were housewives. It was observed that the majority of 93 (93.0%) patients had regular menstrual history. Concerning the clinical indices, anaemia was found 69 (69.0%), jaundice 08 (8.0%) and edema 24 (24.0%). Primi para was found 59 (59.0%) and multipara was 41 (41.0%). Primigravida was found 08 (8.0%) and multigravida was 92 (92.0%). In this study, 76 (76.0%) patients had spontaneous delivery, 05 (5.0%) patients had massive blood loss, and 10 (10.0%) patients required further massage. Conclusions: Carbetocin appears to be an effective new drug in the active management of third-stage labor (AMTSL). A single dose (100 mg) of IV carbetocin is more effective for maintaining adequate uterine tone

Clinical and radio-angiographic features of paediatric moyamoya disease in Bangladesh

Background: Moyamoya disease is a cerebrovascular arteriopathy of unknown origin characterized by progressive stenosis followed by occlusion of the cerebral arteries. Studies on moyamoya disease, especially in children in Bangladesh, are rare. We aimed to determine the clinical and neuroimaging features of moyamoya disease, particularly angiographic features. Methods: Forty children diagnosed with moyamoya disease were consecutively recruited from Bangabandhu Sheikh Mujib Medical University Hospital, Dhaka, Bangladesh. Each patient underwent a medical history and physical examination focusing on stroke, magnetic resonance imaging, and magnetic resonance angiography scans of the brain. In some instances, electroencephalogram and digital subtraction angiography were also performed. Results: Of the 40 patients, 22 experienced their first-ever stroke (median age, 84 months), and 18 had recurrent strokes (median age, 90 months). Common symptoms included hemiparesis, headache, seizure, and speech disorder. The commonly affected vessels were the internal carotid and middle cerebral arteries. Cortical involvement was found in 82.5% of cases. Bilateral involvement was observed in 37.5% of the patients, most of whom were in the Suzuki stage III. Conclusion: Hemiparesis, headache, seizure, and speech disorder were the common manifestations. Most patients reported late (Suzuki stages III and IV), indicating an advanced stage.  Early detection is necessary, considering the severity of the disease and its inherent tendency for recurrence.
