Some algebraic invariants of the edge ideals of perfect [h,d]-ary trees and some unicyclic graphs

This article is mainly concerned with computations of some algebraic invariants of quotient rings of edge ideals of perfect [h,d]-ary trees and unicyclic graphs. We compute exact values of depth and Stanley depth and consequently projective dimension for above mentioned quotient rings, except for the one special case of unicyclic graph for which best possible bounds of Stanley depth are given

Transvaginal Ultrasonographic Findings of Infertile Females in Population of Lahore

Failure of conception in women after frequent unprotected intercourse for one year is known as infertility. Ultrasound examination can detect certain pathologies that may result in primary or secondary infertility. Objective: To describe the various transvaginal ultrasonographic findings of infertile females in population of Lahore. Methods: The study was started after the consent of ethical committee of the University of Lahore. All the patients were registered in this study after signing the informed consent form. Toshiba Xario with transvaginal transducer frequency ranging from 9-12 MHz was used. Pathologies were evaluated through transvaginal scanning and sonographic data was kept in the ultrasound machine. A consecutive sampling technique was used and data was further evaluated with the help of Statistical Package for the Social Sciences version 24. Results: Among 138 females, PCOS was seen in 40.6% of the subjects. The second most common pathology was ovarian cyst which was seen in 10.9% of subjects. And the incidence of multiple fibroids was 5.1% as third most common pathology in both primary and secondary infertility cases. Most ovarian pathologies were found to be bilateral. 12.3% subjects had no findings on ultrasound. Conclusion: PCOS was the utmost common pathology connected with primary and secondary infertility. The second and third most common pathologies were ovarian cyst and multiple fibroids respectively. Keywords: female infertility, PCOS, PID DOI: 10.7176/JBAH/10-12-05 Publication date:June 30th 202

Objective To assess the effectiveness of a community based lifestyle intervention on blood pressure in children and young adults in a developing country setting

Optimizing the Control of a Wi-Fi based Teleoperated Mobile Wheelchair

The purpose of this project is to optimize an educational robotics platform built for students to be presented with a meaningful real-world problem: lack of control options available for people with different levels of disabilities to control a wheelchair. For this purpose, the Wi-Fi based wheelchair controlled by an Android application, is optimized. We established a robust wireless communication method and supplemented the multimodal control options with a speed regulation and GPS navigation system. The end- result is an expansible framework that can extend to other robots sold by the sponsoring company at DEPUSH Technology Co. Ltd., based in Wuhan, China

Reinvigorating the "In Their Shirtsleeves" Industrial Exhibit at the Worcester Historical Museum

The goal of this project was to reinvigorate the "In their Shirtsleeves" exhibit to update the historical timeline, and make the experience more engaging and memorable. To meet this goal, we conducted a site assessment, investigated recent economic developments in Worcester, interviewed industrial professionals, researched "best practices" through case studies, and visited other museums to observe interactive technologies and visitor trends. Our analysis suggests that the application of interactive technology provides options for a small museum including increased visitor engagement, understanding, and interest. Based on these findings and results, we recommended strategies that the museum can use to develop an interactive and engaging exhibit that encompasses recent industrial trends

Evaluation of visual outcomes with toric intraocular lens implantation using digital marker during cataract surgery

Objective: To assess the visual improvement and mean residual astigmatism in patients who underwent cataract surgery with toric intraocular lens. Method: The retrospective, observational study was conducted at the Department of Ophthalmology, Aga Khan University Hospital, Karachi, and comprised data from January 1, 2018, to December 31, 2020, related to adult patients who had regular astigmatism of at least 0.75D and underwent cataract surgery with toric intraocular lens implantation using a digital marker. The patients were followed up on post-operative days 1, 7, 30, 90 and 180. Along with age, the degree of astigmatism was noted. The visual acuity was calculated pre- and post-operatively. The mean residual astigmatism was then noted for all patients post-operatively. Data was analysed using SPSS 22. Results: The sample comprised 240 eyes of 177 patients; 99(55.9%) males and 78(44.1%) females. The mean age of the sample was 62.5±10.6 years. The mean unaided visual acuity improved post-operatively from 0.57±0.38 to 0.07±0.22 at 90 days. At the 30-day follow-up, mean residual astigmatism had reduced from 1.52±0.84 to 0.01±0.09 (p<0.001). The mean intraocular lens rotation from the intended axis was 0.73°±0.92° on day 30. Conclusion: Toric intraocular lens implantation using a digital marker could effectively reduce the post-operative cylinder, and improve the unaided visual acuity following cataract surgery.

Circulation of single serotype of Dengue Virus (DENV-3) in New Delhi, India during 2016: A change in the epidemiological trend

Background: Dengue is a rapidly emerging arthropod borne viral infection affecting tropical and sub-tropical regions of the world. Dengue is an acute febrile illness but sometimes causes more fatal complications like dengue haemorrhagic fever (DHF) and dengue shock syndrome (DSS). Delhi, the capital of India has become hyper endemic for dengue virus because all the four serotypes are circulating here. Methods: The present study describes the identification of dengue virus from clinical samples collected from the suspected dengue patients from New Delhi, India during 2016. The CprM region of Dengue virus genome was analyzed for phylogenetic, selection pressure and Shannon entropy analyses. Results: The present study reports circulation of a single serotype (DENV-3) in New Delhi, during 2016. The phylogenetic analysis revealed that Indian subcontinent (genotype III) of DENV-3 was circulating in Delhi during this period. Neutral selection pressure in the analyzed region revealed relatively conserved nature of this part of the Dengue virus genome. Amino acid at 31 was positively selected and had high entropy value suggesting probability of variation at this position. Conclusions: The changing trend in circulation of dengue virus serotypes necessitates the continuous epidemiological surveillance for the dengue outbreaks in this region.

Community based lifestyle intervention for blood pressure reduction in children and young adults in developing country: cluster randomized controlled trial

OBJECTIVE: To assess the effectiveness of a community based lifestyle intervention on blood pressure in children and young adults in a developing country setting. DESIGN: Cluster randomised controlled trial. SETTING: 12 randomly selected geographical census based clusters in Karachi, Pakistan. PARTICIPANTS: 4023 people aged 5-39 years. INTERVENTION: Three monthly family based home health education delivered by lay health workers. MAIN OUTCOME MEASURE: Change in blood pressure from randomisation to end of follow-up at 2 years. RESULTS: Analyzed using the intention to treat principle, the change in systolic blood pressure (adjusted for age, sex, and baseline blood pressure) was significant; it increased by 1.5 (95% confidence interval 1.1 to 1.9) mm Hg in the control group and by 0.1 (-0.3 to 0.5) mm Hg in the home health education group (P for difference between groups=0.02). Findings for diastolic blood pressure were similar; the change was 1.5 mm Hg greater in the control group than in the intervention group (P=0.002). CONCLUSIONS: Simple, family based home health education delivered by trained lay health workers significantly ameliorated the usual increase in blood pressure with age in children and young adults in the general population of Pakistan, a low income developing country. This strategy is potentially feasible for up-scaling within the existing healthcare systems of Indo-Asia
