The weakness started gradually, progressed over a period of 12 months and stabilized. Few months after the onset of right-sided weakness, he noticed weakness in the left hand and forearm which increased over a period of 3 months before stabilizing. Neurological examination demonstrated moderate to severe atrophy of distal upper extremity muscles, preserved reflexes and normal sensory findings. Electrophysiological studies revealed neurogenic changes in the muscles innervated by lower cervical spinal cord. Magnetic resonance imaging showed atrophy of mid-cervical cord with high signal intensity in the anterior horn cell region. These examination and investigation findings were compatible with the diagnosis of juvenile muscular atrophy of distal upper extremities (JMADUE) also known as Hirayama disease.

The results of the ARDL bounds testing indicate the presence of cointegration among the variables. The estimated long-run impact of gas consumption (0.49) on economic growth is greater than other factor inputs suggesting that energy is a critical driver of production and growth in Pakistan. Furthermore, the results of causality test and variance decomposition analysis suggest a unidirectional causality running from natural gas consumption to economic growth. Gas being the primary source of energy in Pakistan, the implications of this study is that natural gas conservation policies could harm growth and, therefore, requires the policy makers to improve the energy supply efficiency as well as formulate appropriate policy to attract investment and establish public-private partnership initiatives. 10 Extracted from Saten and Shahbaz (2010) 11 Panel cointegration growth. Since gas serves as an important factor input of growth, policy makers planning for the future economic development in Pakistan should synchronize the progress and development of the energy sector in particular the gas industry.

The direction of causality between coal consumption and economic growth is useful for policy making, however, existing empirical evidence have failed to reach a consensus. This paper examined the liaison between coal consumption and economic growth for Pakistan over the period 1971-2009. The endogenous two-break LM unit test, derived in , is used to assess the order of integration of the variables and structural breaks in the data series. Application of the Autoregressive Distributed Lag (ARDL) bounds test reveals a cointegrating relationship between real income, real capital stock, labour and coal consumption, and further application of General to Specific GETS), Engle and Granger (EG), Stock Watson's Dynamic Ordinary Least Squares (DOLS) and Phillip Hansen's Fully Modified Ordinary Least Squares (FMOLS) methods show statistical robustness of the estimates. The elasticity with respect to coal consumption is positive and significant. The Vector Error Correction Model (VECM) based Granger causality test is also applied for both short-and long-run situations. 2 These facts have been extracted from the World Development Indicators (2010).

Regional Irrigation Business Partnerships (RIBPs) can form the focus for irrigation business investment in a region involving interactive feedback between research, operations and policy underpinned by an understanding of the system's biophysical characteristics. In Australia four research regions have been selected by CRCIF and its partners, Macintyre Brook catchment in QLD, Limestone Coast in SA, Coleambally Irrigation Area and South Creek catchment in NSW. The development of a valid conceptual model and associated visualisation for the hydrogeology of the irrigated region is the most important step in the development of any planning and decision making policy framework for the irrigation industry. This also forms the basis for numerical model development. The three dimensional (3-D) representation of irrigation systems is significantly valuable in comprehensively understanding the irrigation system, in particular, its hydro-geological characteristics in the spatial context. It allows simple and clear visual representation of complex information about natural systems to aid understanding by stakeholders from both technical and non-technical background.
