The new and faster slashers and high-speed looms require better-quality yarns from the spinners and, subsequently, new size products. In this article, the author discusses the results of experimentation with starch sizing of sheeting. Some formulations are presented most of which weave satisfactorily.

In this letter, we present a monocular simultaneous localization and mapping (SLAM) algorithm using high-level object and plane landmarks. The built map is denser, more compact and semantic meaningful compared to feature point based SLAM. We first propose a high-order graphical model to jointly infer the three-dimensional object and layout planes from single images considering occlusions and semantic constraints. The extracted objects and planes are further optimized with camera poses in a unified SLAM framework. Objects and planes can provide more semantic constraints such as Manhattan plane and object supporting relationships compared to points. Experiments on various public and collected datasets, including ICL NUIM and TUM Mono show that our algorithm can improve camera localization accuracy compared to state-of-the-art SLAM, especially when there is no loop closure, and also generate dense maps robustly in many structured environments.

Candida shehatae carbon metabolic pathways are correlated with fermentative activity under different growth conditions. Reduced nicotine adenine dinucleotide (NADPH) is the coenzyme preferred for xylose reductase by C. shehatae under in vitro anoxic cell culture conditions. To prevent a redox imbalance derived from intracellular accumulation of NADH in the second enzymatic step of xylose metabolism, the operation of phosphoketolase via in addition the classic pentose phosphate pathway essential for NADH dissimilation is suggested. Variation in cultivation conditions showed a different NADH/NADPH ratio coupled to xylose reductase activity. The existence of two xylose reductases is discussed. Like ethanol, xylitol accumulates only under oxygen-limited or anaerobic conditions. Xylitol accumulation under anaerobic conditions was higher when using respiring cells than respirofermentative cells. This fact suggests that cells pregrown under oxygen limitation are better adapted to starting alcoholic fermentation than cells previously grown under aerobic conditions.

Introduction: Malignant pelvic tumours are rare, but adequate treatment is difficult because of anatomical and functional reasons. Different surgical procedures are recommended. Besides aspects influencing the quality of lift: due to the different surgical techniques, costs of these surgical procedures and the perioperative time interval, depending on the chosen surgical procedure, must also be considered. Methods: Costs of three kinds of surgical treatment - internal hemipelvectomy vs external hemipelvectomy and application of an orthotic device vs ilio-femoral pseudoarthrosis - were compared, including costs of the immediate period of rehabilitation. Costs of the preoperative diagnostic procedure were excluded because they were assumed to be equal. For all calculations, treatment of a periacetabular pelvic tumour type II-b was assumed, according to the Enneking classification, with the need for a pelvic resection with wide margins including removal of the hip joint. This analysis was performed based on the average costs per hour of physicians, nurses and physiotherapists, including a basic daily rate for additional costs, such as housekeeping and administrative costs of the hospital. In all cases, the costs of the operative procedure and the perioperative period up to 3 months were calculated, including the costs for the endoprosthetic device after internal hemipelvectomy and those for the orthotic devices after necessary external hemipelvectomy. Results: For a postoperative period of 3 months, the cost for treatment with resection of the tumour and performing an ilio-femoral pseudoarthrosis is nearly DM 56,741.54;treatment with an internal hemipelvectomy including the endoprosthetic pelvic replacement costs DM 81,439.34;and treatment with external hemipelvectomy and application of an orthotic device with a pelvic cage costs DM 69,138.46. In this analysis, social costs due to the different rates of disability for years or costs of a new prosthetic device after yea
