. Users are given the option to either select an operational data rate manually or to let the device automatically choose the appropriate modulation scheme (data rate) to match the prevailing conditions. Automatic rate selection protocols have been studied for cellular networks but there have been

This study investigates the statistical relationship between climatic variables and aspects of cot-ton production (G. barbadense), and the effects of climatic factors prevailing prior to flowering or subsequent to boll setting on flower and boll production and retention in cotton. The effects

The rural economy was strong in 2007. Record farm incomes were fueled by rising ethanol demand and by stronger export demand, which was driven in part by a weaker dollar. Farmers used the year’s higher profits both to strengthen their financial conditions and to boost investment in land

Mr. President. I wish to thank you and the Economic, Promotion and Development Commission of the Honorable Chamber of Representatives for inviting me to speak about how our monetary policy decisions affect the country’s financial and lending conditions. The global economy is enduring terribly

The method for cultivating virus agents which was published by Maitland and Maitland (I) in 1928 may be regarded as having provided oneof the most important techniques now available for the study of ultramicroscopic virus agents outside the animal body. In the original method, vaccinia virus was induced to multiply in a medium consisting of minced hens ' kidney, serum and Tyrode solution. The work of the Maitlands was soon confirmed by Rivers, Haagen and Muckenfuss (2) and by Eagles and McClean (3). Although no fundamental changes have been made in the original technique, minor modifications, such as the use of Tyrode solution and tissue alone, the addition of animal sera of various kinds and of tissues of different origins, have been practiced by many observers. The method has also become useful in the cultivation of Rickettsiae by the modification first suggested by Nigg and Landsteiner (4), who used tunica vagina]is tissue of guinea pigs and guinea pig serum, with or without

ABSTRACT (edited) Background: PA is the main cause of respiratory failure in cystic fibrosis (CF) patients. Its persistence in the lung is associated with its capacity to form biofilms, against which ABs are considered poorly active. We set up an in vitro model allowing for pharmacodynamic comparison of AB activity against PA biofilms grown in MHB or in ASM (mimicking the physicochemical

of implementation. The prevailing view is, however, that it is extremely susceptible to noise and hence virtually useless for most purposes. This paper challenges that view, by showing that by preceding the algorithm with a very simple normalization (translation and scaling) of the coordinates of the matched points

bases The aim of this study was to evaluate the effect of localities requirements in seedlings growth characteristics of khaya Senegalensis. The results show significant variation in growth and productivity, which found directly correlated to environmental conditions prevailing in each geographical area

Traffic engineering involves adapting the routing of traffic to the network conditions, with the joint goals of good user performance and efficient use of network resources. In this paper, we describe an approach to intradomain traffic engineering that works within the existing deployed base
