The use of supply chain management and optimisation is of increasing importance in the forest industry. The overall wood-flow starts with standing trees in forests and continues with harvesting, bucking, sorting, transportation to terminals, sawmills, pulp mills, paper mills and heating plants, conversion into products such as pulp, paper, lumber, and ends at different customers. Many planning ...

BACKGROUND The adverse events induced by intubation and extubation may cause intracranial hemorrhage and increase of intracranial pressure, especially in posterior fossa surgery patients. In this study, we proposed that I-gel combined with tracheal intubation could reduce the stress response of posterior fossa surgery patients. METHODS Sixty-six posterior fossa surgery patients were randomly ...

The development of economical and sustainable eco-friendly renewable source powered power electronic converters have become more attractive in various areas such as automotive, household industrial applications etc., Bucking boosting voltage according to the requirement is also much needed. So, this work proposes a solar PV single switch buck-boost converter which reduces implementation cost, m...

This paper presents multi-objective topology and sizing optimization of a morphing wing structure. The purpose this is to design new aircraft structure with tapered shape for ribs, spars, skins including torsion beam external actuating torques, which anticipated modify the aeroelastic characteristic using optimization. Two problems are proposed employing ground element structures high- low-grid...

BACKGROUND Foreign body aspiration may be a life-threatening emergency in children requiring immediate bronchoscopy under general anesthesia. Both controlled and spontaneous ventilation techniques have been used during anesthesia for bronchoscopic foreign body removal. There is no prospective study in the literature comparing these two techniques. This prospective randomized clinical trial was ...

Introduction: Because of airway stimulations during bronchoscopy and lack of direct access to the airway, preferred method of anesthesia for rigid bronchoscopy is already controversial. In this study we compared inhalation anesthesia with total intravenous anesthesia (TIVA) for rigid bronchoscopy. Method and Materials: 30 patients aged 2-6 years were chosen divided into two same groups. Anesthe...

BACKGROUND Reversible splenial lesion syndrome (RESLES) is a newly recognized syndrome, and a reversible progress associated with transiently reduced diffusion lesion in the splenium of the corpus callosum (SCC) is the typical pathological finding. The routine clinical symptoms include mildly altered states of consciousness, delirium, and seizures. METHODS We presented a 14-year-old patient w...

As oil and gas industry is developing towards deeper ocean area, the length flexibility of pipes become larger, which may induce larger-amplitude displacement flexible pipe response due to lower structural stiffness against environmental operational loads. Moreover, these also convey internal flow. In other words, dynamic characteristics flow-conveying face great challenge, such as bucking flut...

Studies on hybridization have proved critical for understanding key evolutionary processes such as speciation and adaptation. However, from the perspective of conservation, hybridization poses a concern, as it can threaten the integrity and fitness of many wild species, including canids. As a result of habitat fragmentation and extensive hunting pressure, gray wolf (Canis lupus) populations hav...
