The impact of card cylinder speed, card production rate and draw frame doubling on cotton yarn quality parameters was investigated by using the BoxBehnken experimental design. It was found that yarn tenacity, elongation and hairiness increase by increasing the number of draw frame doubling up to a certain level and then decrease by further increase in doubling. Yarn unevenness increased by incr...

Synaptic plasticity - the directed modulation of synaptic connections by specific activity histories or physiological signals - is believed to be a major mechanism for the modification of neuronal network function. This belief, however, has a 'flip side': the supposition that synapses do not change spontaneously in manners unrelated to such signals. Contrary to this supposition, recent studies ...

Several species of sea cucumbers, all belonging to a single family, possess a peculiar and specialized defense system, the Cuvierian tubules. It is mobilized when the animal is mechanically stimulated, resulting in the discharge of a few white filaments, the tubules. In seawater, the expelled tubules lengthen considerably and become sticky upon contact with any object. The adhesiveness of their...

OBJECTIVE This study was to evaluate the efficacy of the hyaluronic acid (HA) bioabsorbable membrane combined use with both expanded-polytetrafluoroethylene (ePTFE) and autologous pericardium for preventing postoperative pericardial adhesions. METHODS The HA bioresorbable surgical membrane (Seprafilm, Genzyme, Cambridge, Mass) was used with either ePTFE or autologous pericardium in an experim...

Research on lignin biodegradation has become of great interest, due to the fact that lignin is one of the most abundant renewable materials, next to cellulose. Lignin is also the substance that gives color to raw flax fibers. In order to bleach the flax and to keep its tenacity high enough for textile applications, it is necessary to remove the lignin and partially to preserve the pectin. Ligni...

Using the dual-process model of assimilative-tenacity (TGP) and accommodative-flexibility (FGA), the study aims to identify trajectories of TGP and FGA over five time points within a 9-year period, explore the relationships between the trajectories of TGP and FGA, and explore if participants from distinct TGP and FGA trajectories differed in indicators of well-being and depression. Latent class...

The Q gene is largely responsible for the widespread cultivation of wheat because it confers the free-threshing character. It also pleiotropically influences many other domestication-related traits such as glume shape and tenacity, rachis fragility, spike length, plant height, and spike emergence time. We isolated the Q gene and verified its identity by analysis of knockout mutants and transfor...

Based on the associated network of passenger and freight transport in New Western Land-Sea Corridor, structure characteristics different years are analyzed using volume volume, resilience is disturbance model. Finally, coordinated development logistics discussed by applying a coupling coordination The results show that, from 2000 to 2018, Corridor has realized evolution spatial pattern “two cen...

The focus of this work was to investigate the cellulose acetate (CA)–viscose (CV) interface in an all-cellulosic compound and evaluate feasibility hydrophobic CA-coatings on viscose fibers. Mechanical strengths foil-CA compounds were investigated by recoding stress-to-strain curves. For equivalent strain, composites generate higher stress than pure CA samples. coating CV fibers, fibers pretreat...

On 19 September 2012, what has so far been the largest known foodborne outbreak of gastroenteritis in Germany broke out in various schools and childcare establishments in the federal states of Berlin, Brandenburg, Saxony, Saxony-Anhalt and Thuringia. A total of more than 11,000 children and youths suffered from diarrhoea and vomiting. Epidemiological studies conducted by the Robert Koch Institu...
