An updated trophic model of the southern Benguela ecosystem in the period 2004−2008 was constructed, complementing trophic models for earlier periods. The model represents the trophic structure of the system after a southward shift of major resources. There was an increase in biomass of small pelagic fish and cephalopods between the 1980s and 2004–2008 periods, accompanied by declines in severa...
Rice yield potential was greatly improved since the green revolution, but the occurrence of lodging often restricts the achievement of potential yield. Currently, it is still obscure about how the lodging-related traits change along with the genetic improvement in yield potential of rice, although much efforts have been devoted to study the trend of and physiological mechanisms underlying chang...
Achange in U.S. patent law in the early 1980s increased the value of patents, particularly for firms in the electronics and semiconductors industry, yet many of the industry’s leading firms did not embrace patenting after the change. We show through an in-depth study of International Business Machines (IBM), the world’s largest patentee, that the company’s practices during much of the 1980s dis...

In this paper, we face the challenge of managing a large number of bulky mobile objects (flying elephants). We sta...
no signs of emerging in response to this pressure, I turned to capsulotomy. And though I do not consider myself an over-nervous surgeon, I confess to have felt a slight feeling of nervousness in every case. The majority of surgeons still adhere to the old operation^ in spite of secondary cataracts. Mr. Eason in the Lancetof July 29th, 1911, gives 30?50 per cent, as the average rate of secondary...
This paper demonstrates the wide variety of systems for the analysis of posterior capsular opacification (PCO). No single system has been proved to be a gold standard and it is difficult to comment on the advantages of one system over another with the limited current knowledge on the effects of PCO on vision. There are few studies that actually compare the different systems of analysis. Researc...
