Desertification, climate variability and food security are closely linked through drought, land cover changes, and climate and biological feedbacks. In Ghana, only few studies have documented these linkages. To establish this link the study provides historical and predicted climatic changes for two drought sensitive agro-ecological zones in Ghana and further determines how these changes have influ
In generally, there is a phenomenon of “free rider” in the establishment of national oil reserves for different countries, which means that they have the tendency of underestimating the strategic oil reserves. This paper attempts to explain this phenomenon from the perspective of non-cooperative game theory. It also analyzes the establishment of strategic oil reserve among different countries base
Utifrån aktuell forskning kring publik och reception, och mot bakgrund av en förskjutning inom samtidens scenkonst mot åskådarnas delaktighet och medansvar söker texten uppvärdera publiken och de många aspekter av teaterhändelsen som receptionsperspektivet aktualiserar, och bidra till en omdefiniering av teaterns problem och dess uppdrag visavi publiken.
Movement data are analyzed to elucidate principles of articulator coordination. Procedures for tracking articulator gestures from x-ray motion films, and results obtained from Swedish and Bulgarian work are reported in Wood [J. Phon. 19, 281–292 (1991), Proc. 3rd Congress I.C.P.L.A., 191-200, Helsinki (1994), Proc. 13th I.C.Ph.Sc., Vol. 1, 392–395, Stockholm (1995), J. Phon. (in press)]. Coarticul
Mozambique is rich in wild fruit trees, most of which produce fleshy fruits commonly consumed in rural communities, especially during dry seasons. However, information on their content of macronutrients is scarce. Five wild fruit species (Adansonia digitata, Landolphia kirkii, Sclerocarya birrea, Salacia kraussii, and Vangueria infausta) from different districts in Mozambique were selected for the
In neurophysiology, investigating brain connectivity within and between different brain structures is of fundamental importance for understanding nervous system function and its relation to behavior. Yet, parallel recordings in multiple brain structures is highly challenging, especially in rodents, which are most commonly employed in neurophysiological research but rather small in size. In this st
BACKGROUND: Particle-stabilised emulsions, so-called Pickering emulsions, are known to possess many beneficial properties, including being extremely stable. Starch granules isolated from quinoa have been used as emulsion stabilising particles. The granules were intact, 1-3 µm in diameter and modified with octenyl succinic anhydride to increase their hydrophobicity. Starch granules, as opposed to m
Excitation-contraction coupling is the physiological process of converting an electrical stimulus into a mechanical response. In muscle, the electrical stimulus is an action potential and the mechanical response is active contraction. The classical Hill model characterizes muscle contraction though one contractile element, activated by electrical excitation, and two non-linear springs, one in seri
To minimize radiation damage, crystal structures of biological macromolecules are usually determined after rapid cooling to cryogenic temperatures, some 150-200 K below the normal physiological range, The biological relevance of such structures relies on the assumption that flash-cooling is sufficiently fast to kinetically trap the macromolecule and associated solvent in a room-temperature equilib
The main missions of the EuPA Education Committee (EuPA-EC) are to promote and enhance the quality of proteomics knowledge by creating educational programs and to initiate European-wide scientific exchange programs for young proteomics researchers. In this first report we present the initial actions we have undertaken in relation to the missions of the EuPA-EC, and the educational activities that
The distinguished alternative GM allotypes localized in immunoglobulin constant heavy G chain IGHG (Fcγ) (GM) genes on chromosome 14q32.3 define two unique variants of respectively IgG3, IgG1 and IgG2 subclasses, with different structures and functions. The IGHG allele (allotypes), expressed in homozygous or heterozygous forms, are assessed by new serological methods. Fixed combinations of γ3, γ1
The effect of hydrogen enrichment to natural gas flames was experimentally investigated at atmospheric pressure conditions using flame chemiluminescence imaging, planar laser-induced fluorescence of hydroxyl radicals (OH PLIF), and dynamic pressure monitoring. The experiments were performed using a third generation dry low emission (DLE) burner used in both SGT-700 and SGT-800 industrial gas turbi
Based on a series of interviews with young activists working in both parliamentarian and extra-parliamentarian contexts, this chapter underscores that political purposes steer the use of communication technology. This is an explicit position gainst technological determinism. The two different categories of activists generated two different kinds of civic cultures.
