The use of plant materials as soil amendments is an uncommon practice amongst major farming communities in Ghana, although it is necessary for soil fertility improvement. An examination of the effects of soil amendments is necessary to encourage the use of under-utilized organic resources in Ghana. Thus, a field experiment was conducted using 8 different tropical plant materials mixed with chicken manure as soil amendments for growth of tomato as a test crop. The plant materials included Leucaena leueocephala, Centrosema pubescens, Sesbania sesban, Gliricidia sepium, Mucuna pruriens, Pueraria phaseoloides, Azadirachta indiea, and Theo- broma cacao. There were two other treatments： one with equivalent amounts of chemical fertilizers and the other with no-fertilizer input （control）. Plant materials were mixed with chicken manure to obtain a uniform carbon-to-nitrogen （C：N） ratio of 5：1. Except the no-fertilizer control, all treatments received the same amount of nitrogen （N）. To clarify the decomposition pattern of the plant materials in soil, an incubation experiment was conducted using only the plant materials before the field experiment. The Glirieidia treatment released significantly more mineral N than the other plant materials in the incubation experiment. However, the tomato fruit yield was not enhanced in the Gliricidia treatment in the field experiment. The known quality parameters of the tested plant materials, such as total N, total carbon （C）, C：N ratio, and total polyphenols, had minimal effects on their mineralization dynamics. Azadirachta showed the best synergistic effect with chicken manure through significantly increasing soil microbial biomass and fruit yield of tomato. This result provides insights into the possible adoption of Azadirachta in combination with chicken manure as a soil amendment in small-scale agricultural holdings.

A 39-year-old male underwent distal gastrectomy for a high grade gastrointestinal stromal tumor(GIST) . Computed tomography(CT) and magnetic resonance imaging(MRI) 107 mo after the operation,revealed a cystic mass(14 cm in diameter) and a solid mass(9 cm in diameter) in the right and left lobes of the liver,respectively. A biopsy specimen of the solid mass showed a liver metastasis of GIST. The patient received imatinib mesylate(IM) treatment,400 mg/day orally. Following the IM treatment for a period of 35 mo,the patient underwent partial hepatectomy(S4 + S5) . The effect of IM on the metastatic lesions was interpreted as pathologic complete response(CR) . Pathologically verified cases showing therapeutic efficacy of IM have been rarely reported.

Non-cooperative optimization games in market-oriented overlay networks： an integrated model of resource pricing and network formation

引用

Frontiers of Computer Science 2011年第4期5卷 496-505页

作者： Yutaka OKAIE tadashi NAKANO Graduate School of Engineering Osaka University Suita Osaka 565-0871 Japan

In this paper, we formulate a non-cooperative optimization game in market-oriented overlay networks where participating peers share their own computing resources to earn virtual money called energy. We model an overlay network as a set of non-cooperative resource providing peers, called platforms, that perform resource pricing and topology management to maximize their own energy gains. Resource consuming peers, called agents, are simply designed to migrate platform-to-platform to find the least expensive resources in the network. Simulation results are presented to demonstrate the market dynamics as well as the global properties of the network, i.e., resource price and network topology, that emerge from local interactions among the group of peers.

Karyotype differentiation and reproductive isolation among natural populations of Drosophila lacertosa

引用

Cell Research 2003年第6期13卷 491-497页

作者： HIDE AKI WATABE,tadashi AOTSUKA Biological Laboratory Sapporo College Hokkaido University of Education Sapporo 002-8502 Japan Department of Biology Tokyo Metropolitan University Hachioji-shi 192-0397 Japan

Drosophila lacertosa is widely distributed from northern India to Far East of Russia throughout China. We have studied geographical distributions of three kinds of chromosomal karyotypes, type D (2n=10, 4 pairs of V-shaped metacentric chromosomes and a pair of micro-chromosomes), type L (2n=10, 5V with a pair of large-sized hetero chromatic autosomes) and type M (2n=10, 5V with middle-sized ones). Type D was found exclusively in local populations of D. lacertosa distributed in Yun-Gui Plateau, southwestern China. Both type L and M have a wide range of distribution, and the former occurred in subtropical regions of China including Taiwan Island, whereas the latter in cool temperate regions of East Asia covering Far East of Russia, Korea and the Japan Islands. A strong pre mating isolation was detected between flies with type D and those with type L or M. These data demonstrate that genetic differentiation leading to cryptic speciation might have occurred in natural populations of Drosophila lacertosa.
