Laboratory generated spent bleached liquor from the chlorination, caustic extraction stage of mixed wood kraft pulp processing has been analyzed both qualitatively and quantitatively for various resin & fatty acids by using GC. A number of resin acids, saturated and unsaturated fatty acids, chloro fatty and resin acid have been detected and their concentrations are estimated. The results are compared with results on different agriculture residue/hardwood pulps, which were reported earlier. The concentrations of various compounds detected have also been compared with their reported LC50 values.

The use of K2nbF7 as a probe solute for the cyclic voltammetric determination of oxide in FLInAK melts was studied and demonstrated. This method is based on a complex reaction and the peak current density of nbF72- reduction. The reaction constant was determined to be very large at 973 K. A cyclic voltammetric standard addition experiment was also employed to determine the amount of oxide in FLnAK melt. The oxide content of FLInAK melts is equal to the amount of nb(V) added minus the amount of nbF72- which is obtained from the voltammogram.

The zircon Sensitive High Resolution Ion Microprobe (SHRIMP) results show that granitoid intrusions in Zhaoyc Gold Belt were emplaced at two periods of Mesozoic: Linglong and Luanjiahe types of granitic intrusions were emplaced between 160 Ma and 150 Ma (late jurassic); Guojialing type of granodioritic intrusions, 130 Ma and 126 Ma (early Cretaceous). All the three types contain at least two major generations of inherited zircons with Precambrian ( >650 Ma) and early Mesozoic ages (200-250 Ma), respectively. The former suggests that these plu-tonic rocks are of crustal origin and that Precambrian basement with component of sialic crust up to 3.4 Ga old ( Middle Archean) exists in the region. The presence of abundant inherited zircons with early Mesozoic age indicates that the Precambrian basement was affected by a major tectono-thermal event, that is the collision of the north and South China blocks, at 250 Ma to 200 Ma. SHRIMP results also indicate that the gold mineralization in the region took place between 126 Ma and 120 Ma.

Background:Patients presenting with large surface area burns are common in our practice;however, patients with a secondary large burn on pre-existing burn scars and grafts are rare and not reported. Case presentation:We report on an unusual case of a patient sustaining a secondary large burn to areas previously injured by a burn from a different mechanism. We discuss the potential implications when managing a case like this and suggest potential biological reasons why the skin may behave differently. Our patient was a 33-year-old man who presented with a 5%TBSA burn on skin scarred by a previous 40%total body surface area (TBSA) burn and skin grafts. Initially assessed as superficial partial thickness in depth, the wounds were treated conservatively with dressings;however, they failed to heal and became infected requiring surgical management. Conclusions:Burns sustained in areas of previous burn scars and grafts may behave differently to normal patterns of healing, requiring more aggressive management and surgical intervention at an early stage.

The shape of an inflorescence varies among cereals,ranging from a highly branched panicle in rice to a much more compact spike in barley(Hordeum vulgare L.)and wheat(Triticum aestivum L.).However,little is known about the molecular basis of cereal inflorescence *** profiled transcriptomes at three developmental stages of the barley main shoot apex—spikelet initiation,floral organ differentiation,and floral organ growth—and compared them with those from vegetative seedling *** analyses identified 3688 genes differentially transcribed between the three meristem stages,with a further 1394 genes preferentially expressed in reproductive compared with vegetative *** assembly and Gene Ontology analysis classified these 4888 genes into 28 clusters,revealing distinct patterns for genes such as transcription factors,histone modification,and cell-cycle progression specific for each stage of inflorescence *** also compared expression patterns of VRS(SIX-ROWED SPIKE)genes and auxin-,gibberellic acid-and cytokinin-associated genes between two-rowed and six-rowed barley to describe regulators of lateral spikelet *** findings reveal barley inflorescence phase-specific gene expression,identify new candidate genes that regulate barley meristem activities and flower development,and provide a new genetic resource for further dissection of the molecular mechanisms of spike development.

Comprehensive studies identify motor neuron spectrum disorders including amyotrophic lateral sclerosis(ALS)as globally rising fatal disorders with the highest prevalence in aging populations,influenced by ethnicity and ancestry(GBD 2016 Motor neuron Disease Colla borators,2018).While~10% of diagnoses involve a family history(fALS),most cases are considered sporadic(sALS).However,population-based studies suggest that even cases without a common index mutation impart heritability(Ryan et al.,2019),indicating a crucial role of rare and as yet unknown genetic denominators.
