Numerical solution of two dimensional stagnation flows of Micropolar fluids towards a shrinking sheet by using SOR Iterative Procedure
In this paper, the problem of two dimensional stagnation flows of micropolar fluids towards a shrinking sheet has been solved numerically by SOR iterative procedure. The similarity transformations have been used to reduce the highly nonlinear partial differential equations of motion to ordinary differential equations. The resulting equations are then integrated by using appropriate numerical techniques. The results have been calculated on three different grid sizes to check the accuracy of the results. The numerical results have been obtained for various values of the parametera. For, the problem relates to the stagnation flow towards a stretching sheet. For, the problem relates to the flow towards a shrinking sheet. Moreover, the results computed for micropolar case are found in good agreement with those obtained with the Newtonian results
The effectiveness of Technology-assisted Cascade Training and Supervision of community health workers in delivering the Thinking Healthy Program for perinatal depression in a post-conflict area of Pakistan - study protocol for a randomized controlled trial
BACKGROUND: Rates of perinatal depression in low and middle income countries are reported to be very high. Perinatal depression not only has profound impact on women’s health, disability and functioning, it is associated with poor child health outcomes such as pre-term birth, under-nutrition and stunting, which ultimately have an adverse trans-generational impact. There is strong evidence in the medical literature that perinatal depression can be effectively managed with psychological treatments delivered by non-specialists. Our previous research in Pakistan led to the development of a successful perinatal depression intervention, the Thinking Healthy Program (THP). The THP is a psychological treatment delivered by community health workers. The burden of perinatal depression can be reduced through scale-up of this proven intervention; however, training of health workers at scale is a major barrier. To enhance access to such interventions there is a need to look at technological solutions to training and supervision. METHODS/DESIGN: This is a non-inferiority, single-blinded randomized controlled trial. Eighty community health workers called Lady Health Workers (LHWs) working in a post-conflict rural area in Pakistan (Swat) will be recruited through the LHW program. LHWs will be randomly allocated to Technology-assisted Cascade Training and Supervision (TACTS) or to specialist-delivered training (40 in each group). The TACTS group will receive training in THP through LHW supervisors using a tablet-based training package, whereas the comparison group will receive training directly from mental health specialists. Our hypothesis is that both groups will achieve equal competence. Primary outcome measure will be competence of health workers at delivering THP using a modified ENhancing Assessment of Common Therapeutic factors (ENACT) rating scale immediately post training and after 3 months of supervision. Independent assessors will be blinded to the LHW allocation status. DISCUSSION: Women living in post-conflict areas are at higher risk of depression compared to the general population. Implementation of evidence-based interventions for depression in such situations is a challenge because health systems are weak and human resources are scarce. The key innovation to be tested in this trial is a Technology-assisted Cascade Training and Supervision system to assist scale-up of the THP. TRIAL REGISTRATION: Registered with ClinicalTrials.gov as GCC-THP-TACTS-2015, Identifier: NCT02644902
Exploring preference for delivery methods for a psychosocial intervention for prenatal anxiety: A qualitative study from a tertiary care hospital in Pakistan.
ObjectiveThis qualitative study explores therapists' and participants' preferences for delivery methods (face-to-face and phone sessions) of a cognitive behavioral therapy-based psychosocial intervention for prenatal anxiety delivered in a tertiary care hospital.SettingThe research was conducted in a randomized controlled trial in Pakistan, where a shift from face-to-face to phone-based therapy occurred during the coronavirus disease-2019 (COVID-19) pandemic.ParticipantsTwenty in-depth interviews and a focus group discussion were conducted with participants and therapists, respectively. Transcripts were analyzed using thematic analysis.ResultsParticipants generally preferred face-to-face sessions for rapport building, communication, and comprehension. However, barriers like venue accessibility, childcare, and lack of family support hindered engagement. Telephone sessions were favored for easy scheduling and the comfort of receiving the session at home, but there were challenges associated with phone use, distractions at home, and family members' limited mental health awareness. A mix of face-to-face and telephone sessions was preferred, with rapport from in-person sessions carrying over to telephone interactions.ConclusionThis study underscores the need for adaptable intervention delivery strategies that consider cultural norms, logistical challenges, and individual family dynamics. By combining the benefits of both delivery methods, mental health interventions can be optimized to effectively address prenatal anxiety and promote well-being in resource-constrained settings like Pakistan
Scalable Screening and Treatment Response Monitoring for Perinatal Depression in Low- and Middle-Income Countries
Common perinatal mental disorders such as anxiety and depression are a public health concern in low- and middle-income countries. Several tools exist for screening and monitoring treatment responses, which have frequently been tested globally in clinical and research settings. However, these tools are relatively long and not practical for integration into routine data systems in most settings. This study aims to address this gap by considering three short tools: The Community Informant Detection Tool (CIDT) for the identification of women at risk, the 4-item Patient Health Questionnaire (PHQ-4) for screening women at high-risk, and the 4-item Hamilton Depression Rating Scale (HAMD-4) for measuring treatment responses. Studies in rural Pakistan showed that the CIDT offered a valid and reliable key-informant approach for the detection of perinatal depression by utilizing a network of peers and local health workers, yielding a sensitivity of 97.5% and specificity of 82.4%. The PHQ-4 had excellent psychometric properties to screen women with perinatal depression through trained community health workers, with a sensitivity of 93.4% and specificity of 91.70%. The HAMD-4 provided a good model fit and unidimensional construct for assessing intervention responses. These short, reliable, and valid tools are scalable and expected to reduce training, administrative and human resource costs to health systems
Collaborative Public Participatory Web Geographic Information System: A Groupware-Based Online Synchronous Collaboration to Support Municipal Planning
Co-PPGIS has a wide variety of applications like municipal planning, emergency response, public health and security, etc. The main focus of this paper is on the development and design of a web collaborative PPGIS (Co-PPGIS) infrastructure. As part of municipality’s planning and management services, Co-PPGIS is developed for real-time map sharing application system. Co-PPGIS is an effective and essential online meeting system for supporting group collaborations on geographic information such as maps and imageries and capturing and sharing of local/domain knowledge in real time. Co-PPGIS permits amalgamation of geospatial data and collaborator’s input in the form of geo-referenced notations. It incorporates coherent components such as map sharing, real-time chat, video conferencing, and geo-referenced textual and graphical notations. The study aims to focus on public participation and geo-collaboration facilitated with information sharing, interactive geo-conferencing, real-time map, and data sharing with tools to draw features or add annotation to the map while discussions, uploading documents, and live communication. Co-PPGIS provides an efficient and reliable platform that will significantly reduce the time to acquire, process, and analyze data. The significance of this study is to contribute to existing public participation practices, to municipal planning, to decision-making, or to geographic information science
Effect of Creatine Monohydrate Supplementation on Various Hematological and Serum Biochemical Parameters of Male Albino Mice following Neonatal Hypoxia-Ischemia Encephalopathy
Background. Present study was designed to report the effect of 2% creatine monohydrate supplementation for 8, 12 and 15 weeks on hematology and serum biochemical profile of male albino mouse following hypoxic ischemic insult on postnatal day 10. Methods. 66 Blood samples (2% creatine monohydrate supplemented (N=34) and unsupplemented (N=32)) were analyzed for various hematological (blood glucose, packed cell volume, total WBC count, total RBC count) and serum biochemical parameters (cholesterol, AST, ALT, HDL, LDL, total protein, triglycerides). Results. ALT had higher concentrations in mice feeding on normal diet for 8 (P>0.01) and 12 weeks (P>0.01) following asphyxia and in 12 weeks treatment without asphyxia (P=0.006) when compared with the creatine supplemented mice. LDL (P=0.011) and cholesterol (P>0.01) had higher concentrations in mice on normal diet for 12 weeks following hypoxia ischemia. Cholesterol (P>0.01) in 12 and glucose (P=0.006) in 15 week treatment group had significantly lower concentrations in creatine supplemented male albino mice when compared with untreated group following hxpoic-ischemic insult. Conclusion. We concluded that creatine supplementation following hypoxic ischemic insult helps in maintain the normal blood chemistry
