This review discusses imp.rtant research develop.ents and arising challenges in the field of industrial crystallization with an emp.asis on recent p.oblems. The most relevant areas of research have been identified. These are the p.ediction of p.ase diagrams; the p.ediction of effects of imp.rities and additives; the design of fluid dynamics; the p.ocess control with p.ocess analytical technologies （p.T） tools; the p.lymorp. and solvate screening; the stabilization of non-stable p.ases; and the p.oduct design. The p.tential of industrial crystallization in various areas is outlined and discussed with p.rticular reference to the p.oduct quality, p.ocess design, and control. On this basis, p.ssible future directions for research and develop.ent have been p.inted out to highlight the imp.rtance of crystallization as an outstanding technique for sep.ration, p.rification as well as for p.oduct design.

Correlation analysis of solar wind p.rameters, namely solar wind velocity, p.oton density, p.oton temp.rature and mean interp.anetary magnetic field （IMF） from the ACE sp.cecraft data near Earth, was done. To our best knowledge, this study is a novel one since we consider here only the p.rameters inside the solar wind, including the mean IMF and, hence, the solar wind is a self consistent system. We have p.op.sed a Multip.e Linear Regression （MLR） model for the p.ediction of the resp.nse variable （solar wind velocity） using the p.rameters p.oton density, p.oton temp.rature and mean IMF measured as daily averages. About 60% of the observed value can be p.edicted using this model. It is shown that, in general, the correlation between solar wind p.rameters is significant. A deviation from the p.ediction at the solar maximum is interp.eted. These results are verified by a grap.ical method.

On the High p.ains of the USA, herbicides sp.cific for broad-leaf weeds are regularly ap.lied to winter wheat in the early sp.ing, sometimes late enough to coincide with the colonization of fields by cereal ap.ids and their natural enemies. We tested the toxicity of three such herbicides, Ally （Dup.nt）, Rave （Syngenta） and 2,4-D ester （generic）, to neonate larvae of two coccinellid sp.cies imp.rtant in cereal ap.id biocontrol, Coleomegilla maculata DeGeer and Hip.odamia convergens Gurrin-Mrneville. Top.cal treatment of larvae with 2,4-D resulted in 25% and 60% mortality in the two sp.cies, resp.ctively, with surviving C. maculata larvae exp.riencing a 5% increase in develop.ental time. No significant effects were noted for the other two materials, save for a 2.5% increase in develop.ental time for C. maculata larvae exp.sed to Rave. No material caused significant mortality in either sp.cies when larvae were fed on p.ey （Schizap.is graminum Rondani） treated with herbicide 24 h earlier, although 2,4-D reduced develop.ental time slightly in C. maculata. When herbicide ap.lications are delayed enough in sp.ing to coincide with ap.id activity in wheat, farmers can reduce the risk of disrup.ing biological control by selecting an alternative to 2,4-D.

Imp.cts of salinity become severe when the soil is deficient in oxygen. OxygaUon （using aerated water for subsurface drip.irrigation of crop. could minimize the imp.ct of salinity on p.ants under oxygen-limiting soil environments. p.t exp.riments were conducted to evaluate the effects of oxygation （12% air volume/volume of water） on vegetable soybean （moderately salt tolerant） and cotton （salt tolerant） in a salinized vertisol at 2, 8, 14, 20 dS/m ECe. In vegetable soybean, oxygation increased above ground biomass yield and water use efficiency （WUE） by 13% and 22%, resp.ctively, comp.red with the control. Higher yield with oxygation was accomp.nied by greater p.ant height and stem diameter and reduced sp.cific leaf area and leaf Na^＋ and CI^- concentrations. In cotton, oxygation increased lint yield and WUE by 18% and 16%, resp.ctively, comp.red with the control, and was accomp.nied by greater canop. light intercep.ion, p.ant height and stem diameter. Oxygation also led to a greater rate of p.otosynthesis, higher relative water content in the leaf, reduced crop.water stress index and lower leaf water p.tential. It did not, however, affect leaf Na^＋ or CI^- concentration. Oxygation invariably increased, whereas salinity reduced the K^＋： Na^＋ ratio in the leaves of both sp.cies. Oxygation imp.oved yield and WUE p.rformance of salt tolerant and moderately tolerant crop. under saline soil environments, and this may have a significant imp.ct for irrigated agriculture where saline soils p.se constraints to crop.p.oduction.

The Dyson-Schwinger equation of the massless Wess-Zumino model is written as an equation over the anomalous dimension of the theory. Its asymp.otic behavior is derived and the p.ocedure to comp.te the p.rturbations of this asymp.otic behavior is detailed. This p.ocedure uses ill-defined obj.cts. To solve this, the Dyson-Schwinger equation is rewritten for the Borel p.ane. It is shown that the ill- defined p.ocedure in the p.ysical p.ane can be ap.lied in the Borel p.ane. Other results obtained in the Borel p.ane are stated and the p.oof for one result is described.

In contrast to differential equations, p.systems are an unconventional model of comp.tation which takes into consideration the discrete character of the quantity of comp.nents and the inherent randomness that exists in biological p.enomena. The key feature of p.systems is their comp.rtmentalised structure which rep.esents the heterogeneity of the structural organisation of the cells, and where one can take into account the role p.ayed by membranes in the functioning of the system, for examp.e signalling at the cell surface, selective up.ake of substances from the media, diffusion across different comp.rtments, etc. We show here that p.systems can be a reliable tool for Systems Biology and could even outp.rform in some cases the current simulation techniques based on differential equations. We will also use a strategy based on the well known Gillesp.e algorithm but running on more than one comp.rtment called Multi-comp.rtmental Gillesp.e Algorithm.
