Modeling shallow water flows using the discontinuous Galerkin method
Replacing the Traditional Physical Model Approach. Computational models offer promise in improving the modeling of shallow water flows. As new techniques are considered, the process continues to change and evolve. Modeling Shallow Water Flows Using the Discontinuous Galerkin Method examines a technique that focuses on hyperbolic conservation laws and includes one-dimensional and two-dimensional shallow water flows and pollutant transports. Combines the Advantages of Finite Volume and Finite Element Methods.

A Modified Shunt System for the Management of Pyogenic Hydrocephalus
BACKGROUND: To describe the structure and efficacy of a modified cerebrospinal fluid (CSF) shunt system with Bhatti CSF access chamber and ventriculoperitoneal shunt, for the management of hydrocephalus associated with pyogenic ventriculitis. METHODS: This was an observational study performed at the National Medical Center and Ziauddin Medical University, Karachi, Pakistan. Chemically bonded Bhatti CSF access chamber and ventriculoperitoneal shunt was inserted into 443 patients with hydrocephalus and pyogenic ventriculitis to allow injection of antibiotics into the lateral ventricles. RESULTS: In all patients, symptoms and signs of hydrocephalus were relieved immediately after shunt insertion and infection brought under control within two weeks of intraventricular injection of antibiotics (vancomycin or linezolid), via the CSF access chamber. In two patients peritoneal catheter was blocked by a precipitate of vancomycin. Reduction in the dose of intraventricular vancomycin from 50mg to 20mg and increased dilution (additional 2ml of 0.9% N/S solution) prevented recurrence of this complication. All patients recovered from ventriculitis within two weeks of initiating this treatment. Follow-up was from 3 months to 2 years to monitor continued relief of hydrocephalus and absence of recurrence of ventriculitis. CONCLUSION: Bhatti CSF access chamber and the ventriculoperitoneal shunt is the only system available at present that fulfills the management of hydrocephalus associated with pyogenic ventriculitis. It provides continuous internal drainage of CSF combined with access to the ventricles for injection of antibiotics.

Employees' Response to CSR: Role of Organizational Identification and Organizational Trust
Since last decade, Corporate Social Responsibility (CSR) has become an inspiring catch-all in the eyes of researchers. Many studies have been conducted examining the influence of CSR on stakeholders including customers, suppliers and shareholders. However, only a dearth of research is found that attempted to understand its impact on most important stakeholders (i.e. employees). This study aims to understand the relationships among CSR, organizational trust, organizational identification and organizational commitment. The study conducted a questionnaire-based survey of 758 employees working in the banking sector on a random basis. Data was analyzed using structural equation modeling and noted that employee when perceive CSR activities, exhibit trust, identification and commitment to their organization. In addition, organizational trust and organizational identification mediate the relationship between CSR and organizational commitment, while organizational trust mediates the relationship between CSR and organizational identification. The data were collected at one point of time, which restrict researchers to establish causal relationship. The study suggests bankers gain employees' support by engaging in CSR related activities.
