This paper proposes an algorithm for multicast routing in ATMnetworks. We define the network cost of a routing as the combinationof the cost. If establishing connections, the cost of the overallbandwidth and overall switchings, our routing algorithm works on theoriginal topology of ATM networks with physical switches and physi-cal links, and different switching functionalities of VirtualPath(VP)switches and Virtual Channel(VC)switches in the network. Itgenerates an optimal multicast routing with the minimal overallnetwork cost. Simulations with MATLAB have been made to compare thequality of the routing generated by our algorithm with those of othertwo Major algorithms.

There are about 17 chromosomes in yeast Saccharomycescerevisiae.A middle sized chromosome,chromosome V,waschosen in this work for studying and constructing the physi-cal *** V from strain A364a was isolatedby pulsed-field gradient gel electrophoresis(PFGE).Gelslices containing chromosome V DNA were digestedwith two rare cutting enzymes,NotⅠand SfiⅠ,and three6-Nt recognizing enzymes,SmaⅠ,SstⅡ and ApaⅠ.Several strategies-partial or complete digestions,digestion with different sets of two enzymes,and hybrid-ization with cloned genetically mapped probes(CAN1,URA3,CEN5,PRO3,CHO1,SUP19,RAD51,RAD3)——were used to align the restriction *** are 9,9,15,17,and 20 sites for NotⅠ,SfiⅠ,SmaⅠ,SstⅡ and ApaⅠrespectively in the map of the A364a chromosome *** length was calculated to be 620 Kb(Kilo-bases).Thedistributions of the cutting sites for these five enzymesthrough the whole chromosome are not uniform.A comp-arison between the physical map and the genetic map wasalso made.

Marine photosynthesis drives the oceanic biological CO2 pump to absorb CO2 from the atmosphere, which sinks more than one third of the industry-originated CO2 into the ocean. The increasing atmos-pheric CO2 and subsequent rise of pCO2 in seawater, which alters the carbonate system and related chemical reactions and results in lower pH and higher HCO3- concentration, affect photosynthetic CO2 fixation processes of phytoplanktonic and macroalgal species in direct and/or indirect ways. Although many unicellular and multicellular species can operate CO2-concentrating mechanisms (CCMs) to util-ize the large HCO3- pool in seawater, enriched CO2 up to several times the present atmospheric level has been shown to enhance photosynthesis and growth of both phytoplanktonic and macro-species that have less capacity of CCMs. Even for species that operate active CCMs and those whose photo-synthesis is not limited by CO2 in seawater, increased CO2 levels can down-regulate their CCMs and therefore enhance their growth under light-limiting conditions (at higher CO2 levels, less light energy is required to drive CCM). Altered physiological performances under high-CO2 conditions may cause genetic alteration in view of adaptation over long time scale. Marine algae may adapt to a high CO2 oceanic environment so that the evolved communities in future are likely to be genetically different from the contemporary communities. However, most of the previous studies have been carried out under indoor conditions without considering the acidifying effects on seawater by increased CO2 and other interacting environmental factors, and little has been documented so far to explain how physi-ology of marine primary producers performs in a high-CO2 and low-pH ocean.

准噶尔无叶豆是我国荒漠的稀有植物,现已被列入国家重点保护的种类。通过对该植物水分生理生态学特性的初步研究得知:其同化枝水势变化幅度较大,日变化进程为双峰型;蒸腾作用不大,日变化表现为单峰型。蒸腾速率同植物表面温度,大气相对湿度及光照等生态因素有密切关系。经观测统计,在一定的温度范围内,均呈线性关系。
