Parallel associative combinator evaluation II

A new evaluation model for SK combinator expressions is presented and used as a basis for the design of a novel processor. The resulting machine architecture resembles a dataflow ring, but executions are constrained to be fully lazy. An automatic dynamic load sharing mechanism for a distributed multiprocessor architecture is suggested, and initial simulation results are presented.     

Disinfection of wastewaters: high-energy electron vs gamma irradiation

A study was undertaken to examine the sensitivity of a wastewater population of coliphage, total coliforms and total flora present in raw sewage and secondary effluent after irradiating with similar doses delivered by a high-energy electron beam and y -radiation. The electron beam study was conducted on a large scale at the Virginia Key Wastewater Treatment Plant, Miami, Fla. The facility is equipped with a 1.5 MeV, 50 mA electron accelerator, with a wastewater flow rate of 8 ls⁻¹. Concurrent y-radiation studies were conducted at laboratory scale using a 5000 Ci, ⁶⁰Co y -source. Three logs reduction of all three test organisms were observed at an electron beam dose of 500 krads, while at least four logs reduction were observed at the same dose utilizing the y-source.     

Understanding the role of restructuring in flocculation: The application of a population balance model

The effect of shear on floc properties was observed through population balance to comprehend the mechanisms of flocculation, in particular the role of restructuring. Little fundamental attention has been given before to the shear influence responsible for creating compact aggregates, while the floc characteristics might differ in other conditions. It is crucial to understand how aggregates evolve to steady state, if their properties are to be ‘tailored’ to suit subsequent solid-liquid separation. From a previous experimental study (Langmuir 18(6) (2002) 1974), restructuring was observed to occur extensively in the flocculation of latex particles in couette-flow, and was proposed to be responsible for the decrease in floc size on their transition to equilibrium. On the other hand, flocs of larger primary particles were more susceptible to breakage, with densification occurring as a result of fragmentation and re-aggregation. Denser flocs were found when structural deformation dominated, particularly in the initial stage of the process, while comparatively tenuous ones were observed when formation and breakage kinetics were the governing mechanisms. The distinct manners in which aggregates of different primary particle sizes evolved with time, were replicated with a population balance that incorporated the floc structural variation; verifying that restructuring indeed played a crucial role under certain flocculation conditions.     

海洋生物粘接的化学原理

1　引言礁岩潮间带遍布全球 ,而日本最为多见。潮间带生长着大量的座生生物。由于海水流速常常超过10ｍ·ｓ- 1,这些座生生物常常受到巨大的侧向和向上拉力 ,所以座生生物在潮间带生存的必要条件是要有强大并且耐环境侵蚀的粘接能力。仔细查看一下潮间带礁岩表面就会发现许多种永久或半永久吸附其上的生物。藤壶、牡蛎、贻贝、笠贝、管栖性多毛纲生物和海带只是其中少数的几个例子。这类生物的粘接方式之所以引起人们的兴趣 ,是因为它们的粘接策略是随机应变 ,在水下它们可以与所遇到的任何类型的硬质表面 ,例如矿物、石蜡、聚丙烯酸酯、聚…

The production of experimentally labelled aerosols in the sub-micron range     

D.A. Waite  D. Ramsden 《Journal of aerosol science》1971,2(4):425-436

An apparatus for the production of labelled, stable, insoluble particles of ferric oxide in the size range 0·08–0·5 μ is described. The apparatus has a high overall efficiency, and is very suitable for cases when the amount of material to be nebulized is limited.

The characteristics of the particles are examined and the rapid variation of particle density with particle size is studied and explained on a simple semi-empirical theory.

Oxidative degradation of the carbothioate herbicide, molinate, using nanoscale zero-valent iron   总被引：7，自引：0，他引：7  

Joo SH  Feitz AJ  Waite TD 《Environmental science & technology》2004,38(7):2242-2247

Degradation of the carbothiolate herbicide, molinate, has been investigated in oxic solutions containing nanoscale zero-valent iron particles and found to be effectively degraded by an oxidative pathway. Both ferrous iron and superoxide (or, at pH < 4.8, hydroperoxy) radicals appearto be generated on corrosion of the zero-valent iron with resultant production of strongly oxidizing entities capable of degrading the trace contaminant.

Correlations between hand preference and cortical thickness in the secondary somatosensory (SII) cortex of the common marmoset, callithrix jacchus.

Here the authors investigate structural differences in the hemispheres of left- and right-handed common marmosets using surface photography and histology. The hand preferences of 11 marmosets were assessed over their adult life span using a simple reaching task. A significant correlation was found between the length of the right lateral sulcus/brain weight and the % right-hand preference (r = .86, p = .001). Cortical thickness on the superior bank of the right lateral sulcus posteriorly was also positively correlated with % right-hand preference (r = .69, p = .025). Comparison of this site with previously published functional maps of the marmoset cortex show this area corresponds to SII, a region involved in tactile processing and somatosensory discriminations. It is suggested that the correlation between SII thickness and right-hand preference would be consistent with the fact that right-handed marmosets are more proactive than left-handers in exploring novel objects by touch. Enlargement of a cortical area involved tactile discriminations could be a precursor to the evolution of right-handedness as a population bias.
