挪威北部现处于极地地带，但岩溶，尤其洞穴却很发育。现已查明的洞穴达１１００多个，最长的达１１ｋｍ，最深的有６３０ｍ。地表微岩溶形态也丰富。根据野外调查和初步分析，其岩溶发育机制可概括如下：（１）特殊的地质背景：条带状大理岩（相对透水）间夹于片岩（相对隔水）中，这导致了大量的外源水的补给；第三纪以来的强烈抬升导致岩石的变质，以及断裂和一些构造脆弱面的形成；第四纪冰川作用和深切峡湾的形成导致了非常大的水力梯度和水动力场；（２）有利的气候条件，包括非常大的降水量（平均年降水量在３０００～３５００ｍｍ之间），以及冰期间冰期的相互作用（导致周期性的强烈水循环）。特殊的地质背景和有利的条件为岩溶形成提供了有利的水文和水文地质条件。

Eight novel heterobinuclear complexes of Ln3+ and Zn2+ with salicylidene diethylene glycol diamine(SALDA) Schiff base (NO3)22H2O(Ln=Pr, Nd, Sm, Gd, Tb, Er, Yb, Y) were synthesized and characterized on the basis of IR and UV, particularly by1H and13C NMR spectra. It is confirmed that the azomethine nitrogen, ethereal oxygen and a part of phenolic oxygen atoms coordinate to the central ions.

Forest management practices in boreal peatlands increase nutrient export and suspended solids to watercourses calling for development of new water protection *** potential solution could be adsorption-based purification of runoff water using *** aim of this study was to determine the adsorption rate and capacity for Norway spruce and silver birch biochars to design a biochar-filled reactor for a ditch *** a 10-day laboratory experiment,biochar was stirred with runoff water from a clear-cut peatland forest,and changes in water pH,total nitrogen,nitrate nitrogen,ammonium nitrogen,phosphorus,and total organic carbon concentrations were *** on the concentration changes,adsorption was quantified and adsorption model containing the adsorption rate and capacity was fitted to the *** results indicate that biochar effectively adsorbs both inorganic and organic nitrogen from runoff *** biochar had higher adsorption capacity of nitrogen than spruce *** study demonstrates that the adsorption of nitrogen compounds onto biochar surfaces increases with increasing initial ***,aquatic ecosystems exposed to high nutrient loads from fertile peatlands would particularly benefit from biochar-based water purification.

QUANTIZED radiation fields exhibiting nonclassical properties have been of great theoretical andexperimental interest in the last two decades. It is shown that various nonclassical states suchas squeezed state and Schrodinger cat state can be generated out of coherent state in thenonlinear process of the interaction of atom and field although the radiation field in a

SiO2 glasses co-doped with Al3+ ions were prepared by a sol-gel method by holding 0.5% of Ce3+ ions constant and varying the Al3+ ions *** stability,the structural,chemical and the optical properties of the samples were studied by using differential scanning calorimetric(DSC),thermo gravimetric analysis(TGA),X-ray diffraction(XRD),scanning electron microscopy(SEM),energy dispersive spectroscopy(EDS),UV-vis spectroscopy and photoluminescence spectroscopy(PL).The DSC and TGA of samples depicted that the presence of dopant and co-dopant decreased the endothermic peak temperature and the yield *** images showed that the particles were in the nano-range and spherical in *** XRD showed that all the samples were *** UV absorption measurements indicated that the presence of Al3+ ions significantly reduced the SiO2 absorption band,increased the absorbance intensity of SiO2 and decreased the transmittance as compared to the presence of the Ce3+ ions *** photoluminescence results displayed an optimum increase in luminescence intensity when the ratio of Al:Ce was 10:1 and further increase in aluminum content quenched the luminous intensity.
