  concave
Their spectrum of singularities can be computed from ν, which justifies a new multifractal formalism, not limited to concave spectra.

Chondrite-normalized rare earth element patterns are characterized by high ratios of (La/Yb)N, concave-upward shapes of the heavy rare earth element (HREE), and a lack of significant Eu anomalies.

  foveation
In manual aiming, Foveation and PSV procedures resulted in identical results but reduced aiming bias and variability in comparison to the PNV procedures.
      
Successive foveation of the starting base and of the target facilitated this transformation, resulting in direction variability being reduced by more than half in comparison to the PNV and PSV conditions.
      
The activation begins when the stimulus is selected for foveation before the eye actually moves, but is not necessarily predictive for an eye movement.
      
Termination of their activity demanded foveation of some visual targets, not necessarily the one which had initiated their response.4.The majority of these signal-related pre-saccadic tonic cells responded to onset of auditory stimuli.
      
Using this approach we quantify the dynamics of the nystagmus in the region of foveation and present evidence to suggest that it is low-dimensional and deterministic.

A pigmented mass, dendritic in shape, showing on each lateral lobe Surrounding respiratory area, non-pigmented. Posterior sinus trapezoidal Diameter of sucking disk about 1/6 width of carapace, chitinized rods in sucking disk 43-49 in number. Abdomen 0.63-1.13 mm in length and 0.36-0.94 in width longer than broad. Anal papillae basal. Anal sinus about 1/2 length of abdomen.Male: Generally smaller than female, 3.00-4.32 mm in total length. Carapace 1.93-3.48 mm in length, and 1.98-3.18 mm in width. Abdomen, 0.68-1.01 mm in length, and 0.57-0.93 mm in width. Second pereiopod possessing a mitral-shaped process on posterior edge of coxal segment. Third pereiopod possessing a semicircular-shaped posterior capsule on posterior edge both of coxal and basal segments. Fourth pereiopod possessing a projected peg on top of basal segment.The first maxillipeds of three different stages of the larvae in metamorphosis are described. By basing upon the fact shown in the metamorphosis of the first maxilliped of the larval stages, the genus Huargulus seems to be one of the larval stages of the genus Argulus. So the genus Huargulus becomes invalid.This new species was secured from, the lateral line, the surface of abdomen, the gills, and the mucous membrane of the oral cavity of the yellow-barbeled catfish. The last-named location of the parasite is for the first time recorded.

本文通过实际的牵引计算,求出了内燃牵引时各种典型的区间纵断面类型的一些主要的运营指标,经过分析比较,找出了自由导线地段运营上比较合理的区间纵断面类型。研究与分析证明,内燃牵引时区间断面类型对主要运营指标的关系,同我们熟知的蒸汽牵引时的情况基本上相同。内燃牵引时,合理的区间纵断面类型有三种,即全区间均为平道、凹形纵断面和没有有害坡度的凹形纵断面。研究是以停车会让作为基础的,当考虑不停车会让时,全区间均为平道的那种类型将有更显著的优点。

In the present investigation, the heat stability of three samples of silica gel has been studied at different temperatures up to 940℃; and the adsorption isotherms of water, benzene and cyclohexane vapors on the silica gels determined. It has been found that:

本文研究直至940°,青岛细孔硅胶、粗孔硅胶、泰仁硅胶及英国细孔硅胶的热稳定性。并测定水、苯、环己烷蒸气在上述硅胶上的吸附等温线。所得结果如次: 1.经硝酸处理的纯硅胶的热稳定性较未经处理者大。后者于940°灼烧几失去所有的多孔性和活性。但相同条件下,粗孔硅胶之热稳定性较细孔硅胶大。 2.硅胶经600°以上的热处理,其吸水等温线和憎水性硅胶相同,低压下呈凹形。 3.无论细孔或粗孔硅胶,灼烧温度增高,比表面和微孔总体积减少,但硅胶之平均孔半径几不变。 4.较低温下,加热时间(直至四十四小时)不影响硅胶的吸附性能;但高温下(细孔硅胶在600°以上,粗孔硅胶在800°以上)吸附量随灼烧时间延长而减少。 5.硅胶表面经基脱水后再浸水可部分水合,但灼烧温度超过980°,则不能再水合。 6.苯蒸气在粗孔硅胶上的吸附-解吸等温线呈显著的滞后圈,而在细孔硅胶上则无。 7.据水蒸气吸附的结果,说明青岛细孔硅胶的孔性结构与英国B.D.H.细孔硅胶相似。
