To elucidate the dynamics of aluminium(Al),an element potentially toxic and strongly aff ected by acidifi cation processes,in soils,we selected two regions that were similar in relief,soil types,and vegetation cover but diff ered markedly in their history of acid precipitation:the JizerskéMountains(anthropogenically acidifi ed)and the NovohradskéMountains(naturally acidifi ed)in the Czech *** levels of Al forms(exchangeable and organically bound)associated with diff erent environmental impacts were measured and univalent,divalent and trivalent Al species were quantifi ed using HPLC/*** and organically bound Al concentrations were higher in the anthropogenically acidifi ed *** the concentrations of the leastdangerous species,the univalent,in organic soil horizons were similar for both *** concentrations of exchangeable Al forms were correlated with Ca concentrations and with pH in the organic *** known relationship of Al with soil pH was stronger in the mineral *** of exchangeable Al forms concentrations with sulphur concentrations or even more with the sulphur calcium molar ratio were found only in the JizerskéMountains,not in the Novohradské.Generally,the obtained results support the hypothesis that mechanisms diff ered between natural and anthropogenic acidifi cation.

Although tuberculosis has become more common in recent years, it still accounts for just a small percentage of cases of chronic otitis media. Common symptoms of tuberculous otitis media(TOM) include otorrhoea, hearing loss, and multiple tympanic membrane perforations. Due to its rarity, the illness is frequently misdiagnosed. When a patient does not improve with standard antibacterial and antifungal treatment, this may be a possible diagnosis to explore. Complete healing is possible if the illness is diagnosed and treated timely to prevent consequences.

The study focuses on the difficult situation of the Prague Linguistic Circle(PLC) during the Second World War(WWⅡ). Despite the decrease of publication possibilities and censorship in the first years of WWⅡ the activities of the Circle did not substantially change: meetings and lectures went on and also Slovo a slovesnost( Word and Verbal Art) was published until 1943. Nevertheless,a certain decrease of activities came in *** general,during WWⅡ the Circle was one of fewcenters of Czech scholarly effort and thanks to it several key individual works of Vilém Mathesius,Jan Mukaovsky,Bohuslav Havrnek,Jií Veltrusky,Vladimír Skalicka etc. and collective books such as Torso a tajemství Máchova díla(The Fragment and Mystery of Mácha's Work),tení o jazyce a poesii( Reading on Language and Literature) were published. These works significantly helped to preserve a continuity of an important research tradition of the Czech Structuralism,and influenced a further development of Czech linguistics,as well as Czech literary criticism, aesthetics, and theatre studies. The present study focuses also on Jan Mukaovsky's activities during WWⅡ and on his works published at that time.

This study aims to compare the pyrolysis behavior of Huadian oil shale in two infrared heating fixed bed reactors with different directions of infrared *** previous work has shown that fast pyrolysis of oil shale conducted in the shallow fixed bed infrared heating reactor(co-current)presented the massive secondary reactions,which lowered the shale oil production(Siramard et al.,2017).Conversely,the cross-current infrared achieved shale oil yields higher than the Fischer Assay oil yield(13.07 wt%of dry basis),such as 117.7%of the Fischer Assay yield at our realized highest heating rate of 7℃/s under a specified pyrolysis temperature of 550℃.The shale oil from the cross-current infrared heating reactor was obviously heavier than the oil obtained from the cocurrent heating ***,the infrared cross heating evidently suppressed the secondary reactions toward *** realized shale oil yield could reach 13.67 wt%or 122.5%of the Fischer Assay yield under reducing pyrolysis pressure of 0.6 atm,indicating that lower pressure is also beneficial to the release of volatile and reduction of the secondary cracking *** work shows essentially that the infrared cross heating provides an effective merge of the advantages from quick heating and minimization of secondary cracking reactions to enable the shale oil yields being higher than the Fischer Assay oil yield.
