Data Discovery and Dissemination protocol in Wireless Sensor Network

Wireless Sensor Network has widespread its application to various domain whether it is educational, scientific, military, environmental, geographical and many more. With the implementation of secured and distributed data discovery and dissemination (DiDrip) protocol in such sensor networks, communication is efficient and secured. Wireless sensor networks are the distributed, integrated networks and there are some significant challenges to be addressed, for the practical realization of these networking paradigms, such as the increased complexity with large scale networks, their dynamic nature, resource constraints, heterogeneous architectures, absence or impracticality of centralized control and infrastructure, need for survivability, and unattended resolution of potential failures. These challenges have been successfully dealt with by Nature, which, as a result of millions of years of evolution, have yielded many biological systems and processes with intrinsic appealing characteristics such as adaptively to varying environmental conditions, inherent resiliency to failures and damages, successful and collaborative operation on the basis of a limited set of rules. Inspired by these characteristics the current state-of-the-art in bio-inspired networking is captured. The existing bio-inspired networking and communication protocols and algorithms devised by looking at biology as a source of inspiration, and by mimicking the laws and dynamics governing these systems

Turnover Intention and Perceived Organizational Support; Mediating Role of Work Engagement and Organizational Commitment

The purpose of this research is to address practical issues regarding the prediction and prevention of turnover intentions of highly skilled employees by focusing on Perceived Organizational Support and two of its outcomes i.e. Organizational Commitment and Work Engagement. Data was collected from different banks of Lahore i.e; Bank of Punjab, Habib Bank Ltd., Meezan Bank, Alfalah Bank, Standard Chartered, UBL, and MCB were visited. This cross-sectional study has used a quantitative technique in order to collect data from a sample size of 300 respondents. In this study, item response theory is used to select the sample size. To collect the data, the questionnaires were distributed among bankers. The response rate was 93% (i.e. 280 out of 300). Results show that Perceived Organizational support has a high impact on turnover intention whereas the organizational commitment and work engagement both can support the Perceived organizational support. Whereas if Perceived organizational support is increased with the help of Organizational Commitment and Work Engagement there will be less turn over intentions in the Organization

Proximate composition and mineral profile of eight different unstudied date (Phoenix dactylifera L.) varieties from Pakistan

With the aim of extending the knowledge on chemical composition of dates (Phoenix dactylifera L.), eight different sun dried date varieties; (1) Daki, (2) Aseel, (3) Coconut, (4) Khuzravi, (5) Halavi, (6) Zahidi, (7) Deglet Noor and (8) Barkavi were examined to determine their proximate composition and mineral profile. All the date varieties were found to be rich in proteins, fiber, carbohydrates and net gross energy (352.329 Kcal/100 g in Aseel to 425.147 Kcal/100 g in Khuzravi) having suitable levels of lipids and low values of ash, moisture and oxalates. Na, K and Li were found as macrominerals whereas Cr, Cu, Ca, Mg, Ni, Zn and Mn were found as microminerals. The results suggest that all the studied dates serve as good source of vital nutrients and can be considered as premium quality having significantly higher energy values than the earlier reported values for dates

Comparison of Sonographic Quantitative Assessment of Splenomegaly in Thalassemia Patients Receiving Whole Blood and Packed Red Cell Transfusions

Objective: An observational cross-sectional study to assess sonographic splenomegaly quantitatively in thalassemia patients grouped with respect to transfusion given whole blood vs packed red cells. Methods: A study was conducted among 330 patients equally divided into two groups, undergoing an abdominal ultrasound examination with a transducer frequency ranging from 3-5 MHz during the period December 2021 to August 2022. An independent t-test was applied to compare the splenic volume in thalassemia patients given whole blood transfusions versus packed red cells transfusions, and Cohen's d was used to indicate the standardized difference between two ultrasound splenic volume means. Results: The mean splenic volume of the patients who received whole blood cells was 320.62 ± 219.05 cm3, which is greater than the patients who received packed red cells, whose mean was 60.72 ± 58.72 cm3, The splenomegaly was quantitatively assessed in six age groups ranging from 1 to 3 years, 4 to 6 years, 7 to 9 years, 10 to 12 years, 13 to 15 years, and 16-18 years and mean splenic volume in each age group was compared to those receiving whole blood or packed red cells transfusion. there is a statistically significant difference between both transfusion receiving groups, having a larger Cohen’s d size effect of 1.62. Conclusion: Ultrasound is a reliable imaging modality for assessing splenic volume and linear parameters of the spleen with greater splenomegaly in thalassemia patients with whole blood transfusions than those with packed red cells when quantitatively assessed according to relevant age groups. Thalassemia patients should be transfused packed red cells to delay splenomegaly, that should be assessed sonographically

Effect of Kohl-Chikni Dawa – a compound ophthalmic formulation of Unani medicine on naphthalene-induced cataracts in rats

BACKGROUND: Cataracts are the leading cause of blindness worldwide, accounting for 13-27% of cases. Kohl-Chikni Dawa (KCD) is reputed for its beneficial effects in the treatment of premature cataracts. However, its efficacy is yet to be tested. To investigate the rationality of the therapeutic use of Kohl-Chikni Dawa (KCD) in Unani medicine. METHODS: The effect of Kohl-Chikni Dawa eye drops on naphthalene-induced cataracts in rats was investigated by slit-lamp biomicroscopic analysis. The normal group of experimental animals was administered with mineral oil (orally), while other groups were given naphthalene (orally) along with local application of KCD eye drops (once and twice daily), placebo and distilled water (twice daily). Initial morphological changes of the lenses were observed twice a week for two weeks, and thereafter once a week for four weeks. RESULTS: Local application of KCD (twice daily) caused significant reduction in the lens opacification after 2 to 4 weeks of naphthalene administration. CONCLUSION: KCD eye drops may have the potential to delay progression of naphthalene-induced cataracts in rats

Evidence-Based Mental Health Programs in Schools: Barriers and Facilitators of Successful Implementation

Although schools can improve children’s access to mental health services, not all school-based providers are able to successfully deliver evidence-based practices. Indeed, even when school clinicians are trained in evidence-based practices (EBP), the training does not necessarily result in the implementation of those practices. This study explores factors that influence implementation of a particular EBP, Cognitive Behavioral Intervention for Trauma in Schools (CBITS). Semi-structured telephone interviews with 35 site administrators and clinicians from across the United States were conducted 6–18 months after receiving CBITS training to discuss implementation experiences. The implementation experiences of participants differed, but all reported similar barriers to implementation. Sites that successfully overcame such barriers differed from their unsuccessful counterparts by having greater organizational structure for delivering school services, a social network of other clinicians implementing CBITS, and administrative support for implementation. This study suggests that EBP implementation can be facilitated by having the necessary support from school leadership and peers

Numerical study of radiative Maxwell viscoelastic magnetized flow from a stretching permeable sheet with the Cattaneo–Christov heat flux model

In this article, the Cattaneo-Christov heat flux model is implemented to study non-Fourier heat and mass transfer in the magnetohydrodynamic (MHD) flow of an upper convected Maxwell (UCM) fluid over a permeable stretching sheet under a transverse constant magnetic field. Thermal radiation and chemical reaction effects are also considered. The nonlinear partial differential conservation equations for mass, momentum, energy and species conservation are transformed with appropriate similarity variables into a system of coupled, highly nonlinear ordinary differential equations with appropriate boundary conditions. Numerical solutions have been presented for the influence of elasticity parameter (), magnetic parameter (M2), suction/injection parameter (λ), Prandtl number (Pr), conduction-radiation parameter (Rd), sheet stretching parameter (A), Schmidt number (Sc), chemical reaction parameter (γ_c), modified Deborah number with respect to relaxation time of heat flux (i.e. non-Fourier Deborah number) on velocity components, temperature and concentration profiles using the successive Taylor series linearization method (STSLM) utilizing Chebyshev interpolating polynomials and Gauss-Lobatto collocation. The effects of selected parameters on skin friction coefficient, Nusselt number and Sherwood number are also presented with the help of tables. Verification of the STSLM solutions is achieved with existing published results demonstrating close agreement. Further validation of skin friction coefficient, Nusselt number and Sherwood number values computed with STSLM is included using Mathematica software shooting quadrature
