A laser trapping-microspectroscopy technique combined with excitation energy transfer from a fluorescent cationic dye (Rhodamine B, RB+) to a non-fluorescent cationic dye (Malachite Green, MG+) was employed to study pH effects on the diffusion coefficients of MG+ (D(MG+)) in single cation-exchange resin microparticles with the diameters of 16 μm. When RB+-pre-adsorbed resin particles were soaked in an aqueous MG+ solution, the RB+ fluorescence was quenched gradually with the soaking time. The time course of the quenching efficiency of RB+ by MG+ was then used to evaluate the D(MG+) value in the particle. The D(MG+) value increased from 1.1 × 10-11 to 4.3 × 10-11 cm2.s–1 on going the solu- tion pH value from 9 to 4. The results were explained reasonably by a Donnan electric potential model.

Kostka functions K_(λ,μ)~±(t), indexed by r-partitions λ and μ of n, are a generalization of Kostka polynomials K_(λ,μ)(t) indexed by partitions λ,μ of n. It is known that Kostka polynomials have an interpretation in terms of Lusztig's partition function. Finkelberg and Ionov(2016) defined alternate functions K_(λ,μ)(t) by using an analogue of Lusztig's partition function, and showed that K_(λ,μ)(t) ∈Z≥0[t] for generic μ by making use of a coherent realization. They conjectured that K_(λ,μ)(t) coincide with K_(λ,μ)^-(t). In this paper, we show that their conjecture holds. We also discuss the multi-variable version, namely, r-variable Kostka functions K_(λ,μ)~±(t_1,…,t_r).

Terrible scenario for the future aspect of our society was issued by ＂The Limits to Growth＂. Basic problems that we confront are the restricted natural resources and the environment. Regarding the resources, the overall average of the reserve/production ratio is predicted to fall below 10 years by 2040. Aggressive developments of mines based on the sense of urgency for metal resources cause strong conftiction with the environment and the people living there. Resultantly, urban mine becomes more realistic than before. From the view point of ecological foot print, 5.3 globes are needed if all the people living in the world attain the affluent life same as USA. On the other hand, it is clear that we can get larger utility by smaller goods if our scale of satisfaction is reduced. We have to notice that happiness is our ultimate purpose, economy and industry are intermediate, and natural resources support the all from the basis.

A variety of slow release fertilizers, controlled release (availability) fertilizers (CAFs),and stability fertilizers have been developed in response to the serious drawbacks of the conventional fertilizers since the early 1960's. Of these fertilizers, CAFs which are coated with resin are consumed in the largest quantity in the world. Selecting CAFs with higher performance, the author will discuss about: 1) Innovation of agro-technologies for various field crops including new concepts of fertilizer application, 2) high yielding of field crops, 3) enhancing quality and safety of farm products, and 4) controlling the adverse effect of intensive agriculture on the environment.

Updatable timed automata(UTAs) proposed by Bouyer ***., is an extension of timed automata(TAs) having the extra ability to update clocks in a more elaborate way than simply reset them to *** reachability of UTAs is generally undecidable, which can be easily gained by regarding a pair of clocks as updatable counters. This paper investigates a subclass of UTAs by restricting the number of updatable clocks to be one. We will show that(1) the reachability of general UTAs with one updatable clock(UTA1 s)is still undecidable, and(2) that of UTA1 s under diagonal-free constraints is decidable, and the complexity is Pspace-complete. The former is achieved by encoding Minsky machines to the general UTA1 s, where two counters are simulated by the updatable clock. The latter is gained by regarding a region of a UTA1 to be an unbounded digiword, and encoding sets of digiwords that are accepted by a one counter automaton where regions are generated as the value of the counter.

AIM：To evaluate the influence of corneal power on circumpapillary retinal nerve fiber layer（cp RNFL）and optic nerve head（ONH）measurements by spectral-domain optical coherence tomography（SD-OCT）.METHODS：Twenty-five eyes of 25 healthy participants（mean age 23.6±3.6y）were imaged by SD-OCT using horizontal raster *** soft contact lenses of different powers（from-11 to＋5 diopters including 0diopter）were worn to induce 2-diopter changes in corneal *** in the cp RNFL and ONH measurements per diopter of change in corneal power were ***：As corneal power increased by 1 diopter,total and quadrant cp RNFL thicknesses,except for the nasal sector,decreased by-0.19 to-0.32μm（P〈0.01）.Furthermore,the disc,cup,and rim areas decreased by-0.017,-0.007,and-0.015 mm2,respectively（P〈0.001）;the cup and rim volumes decreased by-0.0013 and-0.006 mm3,respectively（P〈0.01）;and the vertical and horizontal disc diameters decreased by-0.006 and-0.007 mm,respectively（P〈0.001）.CONCLUSION：For more precise OCT imaging,the ocular magnification should be corrected by considering both the axial length and corneal ***,the effect of corneal power changes on cp RNFL thickness and ONH topography are small when compare with those of the axial length.
