Abstract

Pitch deposit is one of the most troublesome problems for the paper mills in South China that use the masson pine as a raw material to make paper. The triglyceride has been identified as the main composition accounting for pitch problem. in order to set down effective pitch control scheme, the triglyceride content in papermaking process must be measured quantitatively. A method to measure the content of triglyceride in masson wood pulp was developed based on UV spectrophotometer in the present work. The UV spectrogram and characteristic peak location of standard glycerol trioleate as well as the effect of measuring time on absorbency were discussed. The results showed that at 412 nm the relation between absorbency and consistency of glycerol trioleate was linear and the pertinent coefficient reached 0. 971 in the range of reagent dosage and consistency in this experiment. The absorbency decreased linearly with measuring time and the pertinent coefficient reached 0. 990 2. The results of reproductive experiment showed that the recoveries were 98%-104%0 and the accuracy was 1. 27%-4. 03% for the samples in consistency 1. 25-0. 50 g x L(-1). With this method, the content of triglyceride in hexane extractive of masson TMP and acid SP were measured respectively. The degradative effect of triglyceride before and after enzyme treatment for masson wood pulp was also evaluated. The results showed that the triglyceride content was relatively high, about 50% both in the total extractive of masson TMP and acid SP. After enzyme treatment, the content of triglyceride in masson TMP and acid SP was reduced by 46. 31% and 35. 55% respectively.

Abstract

Treatment of wheat straw with hot water at 80-95 degrees C for 0.5 h at pH 6.0-8.0 released 41.0-53.0% of the original lipophilic extractives. The chemical compositions of six lipophilic extractives were determined by GC on a medium-length high-temperature capillary column without derivatization, thus giving a method for direct determination of individual components of free fatty and resin acids, sterols, waxes, sterol esters, and triglycerides. The extracts contained 68.7-75.8% lipophilic substances, comprising mainly free fatty acids (25.8-48.4%), waxes (9.4-27.0%), sterols (4.1-8.0%), triglycerides (3.3-11.0%), and sterol esters (2.6-5.1%). Minor amounts of diglycerides (0.3-0.5%), resin acid (0.5-3.1%), and phenolic compounds (0.9-3.6%) were also quantitatively determined in the extractives.

Abstract

The authors would like to thank the children and parents who participated in the study and Ana Yara Postigo-Fuentes for the assistance with the English editing., Sedentary habits during childhood are associated with adverse health outcomes. The aim of this work was to cluster lifestyle behaviors and metabolic biomarkers to establish different patterns in children. Their physical and sedentary activities were evaluated by accelerometry, and questionnaires that included lifestyle behaviors, such as adherence to a Mediterranean diet, anthropometry and blood biochemical markers. Cluster analysis was performed to establish different groups based on physical activity levels. A total of 489 children were finally selected. Cluster 1 included children with a mostly sedentary state, whereas Cluster 3 included the most active children and Cluster 2 included children that did not fit into either the sedentary or the highly active groups. In Cluster 3, 56% of children were in a sports club, and a lower percentage used electronic devices in their rooms compared to the other groups. Cluster 1 children exhibited higher insulin, HOMA-IR and triacylglycerides with respect to the other groups. No differences were found regarding adherence to a Mediterranean diet. The choice to practice an extracurricular sport could be an influencing factor to increase exercise and ensure an active lifestyle in children. Reducing or limiting screen time mainly in children’s rooms could contribute to an active lifestyle., Plan Nacional de Investigacion Cientifica, Desarrollo e InnovacionTecnologica (I + D + I), Instituto de Salud Carlos III-Health Research Funding (FONDOS FEDER) PI051968 PI1102042 PI1600871, Redes tematicas de investigacion cooperativa RETIC (Red SAMID) RD12/0026/0015, Instituto de Salud Carlos III IFI17/00048
