RDF has seen increased adoption in recent years, prompting the standardization of the SPARQL query language for RDF, and the development of local and distributed engines for processing SPARQL queries. This survey paper provides a comprehensive review of techniques and systems for querying RDF knowledge graphs. While other reviews on this topic tend...
Article
Congenital aortic arch malformations manifest a broad-spectrum of differences and abnormalities that come from disturbed embryogenesis of branchial arches. Current case was a 10 months old baby girl with length of 69 cm (less than –3 SD) and weight of 5.5 kg (less than –3 SD). The patient had history of recurrent lower respiratory tract infections...
Article
Improvement in outcome of Malignant solid tumor cases is credited to existence of well-defined guidelines and protocols and integrated treatment modalities involving chemotherapy, surgery and radiotherapy. The present case describes a rare case of Wilms tumor extending from the left kidney to left renal vein and then via inferior vena cava into the...

Recent years have seen the growing adoption of non-relational data models for representing diverse, incomplete data. Among these, the RDF graph-based data model has seen ever-broadening adoption, particularly on the Web. This adoption has prompted the standardization of the SPARQL query language for RDF, as well as the development of a variety of l...

Entropy production in a system affects the efficiency of the system because it minimizes the output of the system. For the better performance of the system, it is very important to minimize the entropy production. Entropy generation is always observed in any irreversible process while it remains constant in any reversible process. Second law of the...

In the current study, the effects of fluidic parameters with entropy generation properties on velocity, temperature, and entropy numbers of non‐Newtonian fluid flowing through the porous channel are investigated. The complex system of fluid equations is handled with analytically and numerically. The first‐order perturbation expansion is employed on...

Objectives: Bacterial meningitis is a major global issue. Despite medical advancement in childcare in the last couple of decades, bacterial meningitis is still causing significant mortality and morbidity. We planned this study to find out the frequency as well acute complications related to bacterial meningitis in our setting. Study Design: Observa...
Article
Background The motion of fluids through the micro-tube, micro-channel, membranes, porous material and other fluid conduits because of the applied potential is known as electro-osmotic flow. The electro-osmosis process is a process in which electrodes generate the flow, and these electrodes are placed at each end of the micro-channel in the reservoi...

Article
Objectives: Seizure is considered to be one of the commonest emergency involving more than half of the admissions in Pediatric Neurology wards. It has been well documented that proper management not only improves the prognosis but also decrease complications in these children. This study was planned to compare phenobarbital against sodium valproate...
Article
Objectives: Childhood and adolescent obesity is increasing especially in developing countries like Pakistan. It seem to affect most socio-economic classes as well as all ethnicities and geographies. We planned this study to analyze the clinical and biochemical profile of obese as well as overweight children at a tertiary care hospital for the exist...

In this paper, a study of the flow of Eyring-Powell (EP) fluid in an infinite circular long pipe under the consideration of heat generation and thermal radiation is considered. It is assumed that the viscosity of the fluid is an exponential function of the temperature of the fluid. The flow of fluid depends on many variables, such as the physical p...
