Determinants Of Success In International Involvement Of Large U.S. Corporations

The findings of this study help to identify factors explaining success in international operations of large U.S. corporations. Successful foreign direct investment (FDI) and continuous involvement of large U.S. corporations is crucial for economic development of a country and social uplifting of many citizens of the world. Data were collected on selected U.S. corporations’ perception of the success variables in their international operation. Results indicate that large market size, geographical diversification, and low production/operating cost are the three most important success determinants of international operations

Leadership Of Global Carbon Market

Carbon credits trading and the need to reduce carbon emissions are slowly being accepted as new realities of global business. A number of institutions played crucial role in developing the global carbon market. The World Bank Group, the World Resource Institute, the Institutional Investor’s Group on Climate Change, and the Carbon Disclosure Project are some of the pioneers in developing the global carbon industry. The United States government did not assume the leadership role of the global carbon market as expected by world governments and corporations. The purpose of this study is to analyze the United States government’s position vis-à-vis the global carbon market and explore the leadership role played by other global institutions

Analysis Of Green Financial Markets

Green financial markets are still in early stages of development. There are new green venture capital funds and green stocks to satisfy needs of project developers and investors. Various governments are also subsidizing new green ventures and project developers should take full advantage of these incentives. Also, there have been attempts to quantify riskiness of various green financial products so investors can make informed decisions

Homogeneous Gold Catalysis through Relativistic Effects: Addition of Water to Propyne

In the catalytic addition of water to propyne the Au(III) catalyst is not stable under non-relativistic conditions and dissociates into a Au(I) compound and Cl2. This implies that one link in the chain of events in the catalytic cycle is broken and relativity may well be seen as the reason why Au(III) compounds are effective catalysts.Comment: 12 pages, 3 figures, 1 tabl

Slowing light through Zeeman Coherence Oscillations in a duplicated two-level system

We present the theory of a new method to slow a linearly polarized probe pulse as it propagates through a duplicated two-level system driven by an orthogonally polarized control field. The method makes use of Zeeman coherence oscillations (CZO) that arise in the atomic system because of the spatial and temporal modulation of the total polarization. This method exhibits properties similar to those that rely on the electromagnetically induced transparency (EIT) but without the existence of any trapping state. We demonstrated also the propagation of a dark polariton in the mediumComment: Rapid communication in PRA, 4 pages, 3 figures. Phys Rev A, rapid com. accepted (2008

New horizons: COVID-19 and the burden of neuropsychiatric illness in Pakistan

This manuscript reviews the current state of knowledge about the burden of mental illness and assesses the impact of COVID-19 illness on mental health in Pakistan. For this we analyzed secondary data obtained from the Institute of Health Metrics and Evaluation. The Global Burden of Disease (GBD) study draws from a wide range of data sources to quantify global and regional effects of a disease. We also did a literature search on the effects of COVID-19 illness on mental health and the psychosocial effects of COVID-19 and other Corona virus related illnesses such as SARS-CoV and MERS-CoV. Data from the studies obtained was utilized to extrapolate the anticipated effects of COVID-19 illness on healthcare workers, COVID-19 patients and the general public in Pakistan. Mental illness poses a significant challenge to Pakistan\u27s under resourced health care system. COVID-19 has the potential to strain Pakistan\u27s healthcare system to the breaking point. So far, the general morbidity from COVID-19 illness in Pakistan has been low compared to other countries but this could change in the coming weeks and months. Hidden within this crisis are also some opportunities for both healthcare and education

Prototype system development for wireless vehicle speed monitoring

Vehicle speed monitoring and management of the associated data in an intelligent and efficient way is an important issue in modern transportation system in order to reduce road accidents. The aim of this work is to develop an automatic wireless system for monitoring vehicle speed on the road, identify a speeding vehicle and imposing penalty for the speeding offenders. In this work, a prototype system has been developed in a laboratory environment to generate random speed data using a mechanical wheel, measure the speed data with a Shimmer wireless sensor and transfer the data wirelessly to a client computer for further analysis. Software has been developed using a Java based socket programming technique to monitor the vehicle speed in a server computer and to send the data associated with a speeding vehicle to a remotely placed client computer. The graphical user interface (GUI) can visually display the speed of a vehicle at any particular time. The functionality of the software has been tested by simulating different traffic scenarios with low and high speed limits (40 and 60 km/hr respectively). To do that a high or low speed limit can be set in the GUI. The mechanical wheel is run at different speeds and the GUI continuously displays the speed. If the vehicle speed is higher than the set speed limit for the road, the system automatically detects it and generates a report with the time of speeding, vehicle number, vehicle speed etc. to be saved in the client computer in order to take further necessary actions for the speeding offender

Stiffer alginate gels deposit more efficiently in microchannel flows

The behavior of crosslinking polymer solutions as they transition from liquid-like to solid-like material in flow determines success or failure in several applications, from 3D printing to oil recovery in the earth's subsurface to a wide variety of biological flows. Dilute polymer solutions flow easily, while concentrated polymers or crosslinked polymer gels can clog pores, nozzles, or channels. We have recently uncovered and described a third regime of flow dynamics in polymers that occurs when crosslinking happens during flow: intermittent flows. In a model system of alginate and calcium meeting at a Y-shaped junction in a microfluidic channel, a persistent and regular pattern of intermittent flow occurs when driven at a constant volume flow rate. At the junction, calcium crosslinks alginate to form an alginate gel, which subsequently deposits on the channel wall. As gel continues to deposit, it obstructs the channel, causing the driving pressure to increase to maintain a constant flow rate. At a critical pressure, corresponding to a critical shear stress, the fluid pulls the gel from the wall, removing the gel from the device and resulting in a clear channel. The gel deposit begins again, and the process then repeats as long as flow continues. Chemical concentrations and flow rate control both the frequency of ablation and the critical shear stress. In this work, we provide an analytical framework to quantitatively describe the intermittent behavior as a result of diffusively driven deposition in a high Peclet number flow where convection dominates. Fitting the experimental data to the model allows estimation of the deposition efficiency, or the fraction of flowing material that sticks to the channel walls. By correlating the results of the model with bulk rheology measurements, we find that deposition efficiency increases with the stiffness of the gel formed in flow.Comment: 11 pages, 5 figure
