Success partly relies on the ability to validate subsurface models and model a range of properties, such as reservoir permeability. This is particularly important in the case of tight carbonate reservoirs such as the Eocene Sakesar Formation, where the recovery of economic quantities of hydrocarbons is conditioned by the presence of fracture-enhanced permeability. This requires the application of geological and geophysical modeling techniques to address these challenges, to minimize uncertainty and drive exploration success. The interpretation and structural validation of the Ratana structure presented here allows the proposal of a consistent and robust structural model even in areas of higher uncertainty in the data, such as along faults. The dynamically updatable, watertight, complex 3D structural framework created for the top Sakes...

One of the main challenges is how to build a static reservoir model that integrates rock-property heterogeneity to derive dynamic reservoir models and improve hydrocarbon recovery. Rock properties are measured at different scales by using advanced measurements ranging from 3D surface seismic inversion to log data and core data. The advancement of rock digital imaging has been proven to enhance interpretation results. Digital rock physics plays a vital role by utilizing new technologies such as machine learning to get the best outcome.

In order to sustain and grow, ICT Sector needs to embrace new technologies and develop cost-effective and innovative solutions. Accordingly, the ICT sector must acquire knowledge and skills in new and emerging technologies. However, for most ICT, it could be challenging to bear the cost and complexity of acquiring and adapting emerging technologies. It is important to recognize the main problems, constraints, and challenges faced by ICT Sector of developing and especially ICT sector in Pakistan for the purposes of Technology Transfer from developed countries. This study investigates the barriers and challenges in the achievement of effective technology transfer and how it is effected by poor absorptive capacity and lack of organizational innovation.

Their occurrence, transformation, and fate in the environment are causing significant concerns. Several existing treatment technologies are there with their pros and cons for the treatment of pharmaceutical wastewater (PWW). Still, electrocoagulation is considered as the modern and decisive technology for treatment. In the EC process, utilizing electricity (AC/DC) and electrodes, contaminants become coagulated with the metal hydroxide and are separated by co-precipitation. The main mechanism is charge neutralization and adsorption of contaminants on the generated flocs. The range of parameters affects the EC process and is directly related to the removal efficiency and its overall operational cost. This process only could be scaled up on the industrial level if process parameters become optimized and energy cons...

Any offline configuration of a network when implemented on a real time environment leaves some shortcomings and wrong configuration attributes due to non-availability of Alarms and Performance Management in the presently available offline utility. A simulated platform is developed for implementation of a traffic matrix in an offline environment before implementing over a real time NG SDH Transmission network to reduce the chance of faults or any network disaster.

Objective: To examine the donor characteristics of kidney transplants in Syria and the impact of national Syrian legislation on the evolution of kidney transplantation activities in the private and public sectors. Methods: Available data on all kidney transplants performed in Syria over the last 2 decades was retrospectively analyzed to assess the characteristics of kidney donors and recipients with a focus upon transplants since 2003. The kidney transplant rate has increased from 7 kidney transplants per million populations in 2002 to more than 17 in 2007. In the meantime, a substantial decline in the rate of kidney transplantation performed on Syrian nationals abroad was observed from 65% of all kidney transplantations in 1998 to less than 2% in 2007. Despite the prohibition to buy a kidney in Syria, vendors had found ways to sell their kidneys through disreputable brokers. Potential related donors were not inclined to donate kidneys to their relatives as long as kidneys could be bought from a non-related donor. By 2008, the percent of related donors in private sector represented only 8% of all donors, as compared to 50% in public hospitals. Consequently, in January 2008, the government of Syria issued a pronouncement restricting kidney transplantation to the public sector with a new national regulatory oversight of transplantation practices. Since this 2008 Administrative Order was promulgated, the kidney transplant rate in public hospitals has substantially increased by 55% with the establishment of new public transplant centers in the 3 largest cities in Syria. The recommendations of the Istanbul Declaration and the Revised Guiding Principles of the World Health Organization have yet to be implemented in Syria but the expansion of kidney transplants in the public sector is an important initial step for initiating a deceased organ donation program as an essential component of a comprehensive approach to the problem of the organ shortage.

This heterogeneity significantly affects the system communication performance in terms of throughput and delay. In real-time applications, such as healthcare, military, and radar systems, a slight delay can cause a lot of troubles. Thus, the time factor is very important for those applications where the human life or a lot of investment is concerned. Recently, the Real-Time Publish Subscribe (RTPS) middleware has become one of the effective solutions for the real-time distributed systems problems, due to its proved scalability, reliability, flexibility, and rich set of quality of service policies. In this paper, we develop a real-time architecture for porting the RTPS middleware functions into the healthcare systems. Furthermore, we extensively evaluate the developed system over wired and wireless channels in terms of throughput and delay.

However, there is a paucity of reported data on clinical features of Postural orthostatic tachycardia syndrome (POTS) in patients suffering from JHS. This retrospective study was approved by our local Institutional Review Board (IRB). Over a period of 10 years, 26 patients of POTS were identified for inclusion in this study. All these patients had features of Joint Hypermobility Syndrome (by Brighton criterion). A comparison group of 39 patients with other forms of POTS were also followed in the autonomic clinic during the same time. We present a descriptive report on the comparative clinical profile of the clinical features of Postural Orthostatic Tachycardia patients with and without Joint Hypermobility syndrome. The data is presented as a mean+/-SD and percentages wherever applicable. Out of 65 patients, 26 patients (all females, 20 Caucasians) had POTS and JHS. The mean age at presentation o...

However, pain can be referred to multiple sites including the face, the neck, the abdomen and the contra-lateral arm. We present a case of sudden bilateral ear pain as the sole presentation of acute coronary syndrome in an elderly man. The importance of recognizing these atypical presentations is vital, as outcomes may be worsened as appropriate therapy may be delayed or misdirected.

A complete diagnosis not only checks the current health, but also suggests corrective measures. Diagnostic models suggested by others were evaluated in this paper including some of the authors' previous work and shortcoming i.e. lacking the sustainable development focus in these models of organizational health diagnosis was identified. The main focus of this paper is to incorporate sustainability dimension in the organizational diagnostic model. We therefore propose in this paper an alternative, sustainability embedded model for organizational diagnosis. This model can be used by the organizational diagnosticians to perform a comprehensive organizational diagnosis.
