This study examined the relationship among cash crop exportation, real exchange rate, nominal and volatility. focuses on effects of rate exportation in Nigeria. covers a four-decade period between, 1980 2020. The used pairwise granger, Distributive Lag (ARDL) bounds testing approach to co-integrate long-run variables. outcome shows that there is unidirectional causality between production long ...

Abstract. Characteristics and trends of surface ocean dimethylsulfide (DMS) concentrations fluxes into the atmosphere four Earth system models (ESMs: CNRM-ESM2-1, MIROC-ES2L, NorESM2-LM, UKESM1-0-LL) are analysed over recent past (1980–2009) future, using Coupled Model Intercomparison Project 6 (CMIP6) simulations. The DMS in historical simulations systematically underestimate most widely used ...

Artificial Intelligence has witnessed an exponential growth in the last decade and, thanks to its many successful and pervasive applications, it now become a research field with profound  societal impacts. The interest AI reached all-time high from all sectors of our modern society, including industry, health, education government. Magazine, founded 1980, documented rise elite almost esote...

The paper introduces asymmetric production conditions between firms and asymmetric transaction conditions between countries into the Murphy-Shleifer-Vishny model of industrialization. It explores a general equilibrium mechanism that generates circular causation loop that each firm's profitability and its decision of involvement in a network of industrial linkages and trade flows is determined b...

The incidence of primary intracranial tumors in Manitoba, Canada was reviewed. From 1980 through 1985, 657 tumors were diagnosed. The crude incidence rates were 10.2/100,000 for males and 10.8/100,000 for females. The three most common tumors were: astrocytoma 281 (43%), meningioma 145 (22%), and pituitary adenoma 111 (17%). Average annual incidence rates for all tumors showed a bimodal distrib...

The decay of landfalling tropical cyclones is important to the damage caused. We examine a simple physically based model maximum surface winds driven by frictional turbulent drag and modification accounting for partial complete land roughness. fits an algebraic with parameter determined ratio coefficient effective vortex depth. This has been decreasing from 1980 2018. There also global mean inc...

With a unique biogeophysical signature relative to other freshwater sources, meltwater from glaciers plays crucial role in the hydrological and ecological regime of high latitude coastal areas. Today, as worldwide exhibit persistent negative mass balance, glacier runoff is changing both magnitude timing, with potential downstream impacts on infrastructure, ecosystems, ecosystem resources. Howev...

The 1980’s were the decade when high quality of life was achieved by proper and adequate substitution therapy. However, the tragedy of global spread of HIV infection in people treated with plasma derived products shadowed this progress. At the same time, industrial production of safer products was not only triggered but also successfully accomplished. The identification and cloning of the genes...

Safety and quality in health care have become increasingly prominent themes over the last decade. “Quality assurance” measures were implemented in many areas of health care through the 1980’s, with an emphasis upon clinical audits being followed by the implementation of new or remedial actions, and subsequent measurement of the effect. However, two sentinel studies, one in the USA and one in Au...

An attempt was made to ascertain all cases of Creutzfeldt-Jakob disease occurring in England and Wales during the 5 year period 1980-1984. The mean annual mortality rate was 0.49/million; women were more frequently affected than men. The age-specific mortality rate reached a peak in the seventh decade. A case-control study involving 92 of the 122 definite and probable cases ascertained failed t...
