When the PROTOS cigarette machine for paper printing system is expanding the cigarette paper, it produce a lot of dust which easy to adhere to the ink roller and stamp fonts gap, leading to the cigarette stamp dirty, fuzzy cigarette product quality defects. To solve this problem, a negative pressure vacuum system is installed inside the guide rod of the cigarette paper, which help to discharge the cigarette dust to the dust removal system, and improve guide ring of the guide rod to reducing the friction. The application results show that the negative pressure vacuum is an effective solution to solve the dust floated problem. The unqualified rate reduce from 161.3PPM to 26.1PPM.It improve the effective operation of the device and ensure product quality.

Supply chain quality is the assurance of product quality in its full life-cycle. Although supply chain quality control is a hot topic among researchers, supply chain quality prediction is actually an important but unsolved problem in manufacturing industry. In this paper, an approach of manufacturing supply chain quality prediction based on quality satisfaction degree is proposed to control supply chain better, in order to help ensure product quality. Supply chain quality prediction 3D model and model based on customer satisfaction and process control are established firstly. And then technologies used in quality prediction are studied, including quality prediction index system established on Expert scoring -AHP and prediction workflow built on ABPM. Finally an example is given to illustrate this approach. The customer satisfaction prediction result of supply chain quality can help supply chain management, and the quality prediction software system can make it easier, which provides a new direction for the product quality control technology research.

A one-year-old child operated on for arachnoid cyst in right frontoparietotemporal region had sudden bradycardia followed by cardiac arrest leading to death after connecting negative pressure to the subgaleal drain during craniotomy closure. The surgical procedure was uneventful. It is a common practice to place epidural or subgaleal drains connected to a vacuum system towards the end of craniotomy to prevent accumulation of intracranial and extracranial blood. The phenomenon of bradycardia with hypotension is known to occur following negative pressure application to the epidural, epicranial, or subgaleal space after craniotomy closure. However cardiac arrest as a complication of negative pressure suction drain in neurosurgical patients is not described in the literature.

Recently, there are several problems in space, infra-structure, and facility in the contiguity of existing harbors due to the trend of enlarged container vessels. In this regard, the Mobile Harbor has been proposed conceptually as an effective solution for those problems. This concept is a kind of transfer loader of the containers from the large container ship to the harbor on land, which is a floating barge of a catamaran type. The catamaran-type vessel is well known for its advantage in maneuverability, resistance, and the effectiveness for working on board. For the safe and effective operation of the two floating bodies, a container ship and the mobile harbor in the near sea apart from the quay, robot arms, novel crane systems, and pneumatic fenders are specially devised with additional mooring facility or DP (dynamic positioning) system. The concept is to be verified through comparison and simulation studies under various environmental conditions. It is shown that the proposed concept is in general feasible but there are several areas for further investigation and improvement.

CONTEXT AND OBJECTIVE: Use of topical negative pressure over difficult-to-heal wounds has been studied. The objective of this study was to analyze the effects from negative pressure in the treatment of complex wounds. DESIGN AND SETTING: Case series developed at Hospital das Clínicas, Faculdade de Medicina da Universidade de São Paulo. METHODS: Twenty-nine patients with complex wounds were treated with the vacuum system and then underwent a surgical procedure to close the wound. RESULTS: 85% of the skin grafts took well, and 87.5% of the local flaps were successful, thus demonstrating adequate wound preparation. The wounds were closed within shorter times than observed using other conventional treatments In two cases, the vacuum system was also used to stabilize the skin grafts over the wounds. CONCLUSIONS: Use of the vacuum method is safe and efficient for preparing wounds for surgical closure. It allows for an improvement of local wound conditions, and healthy granulation tissue develops with control over local infection.

Numerous manufacturing processes require extremely low levels of nanoparticulate contamination to ensure product quality. While modern filters efficiently remove nanoparticles, online monitoring of the cleanliness of possibly reactive process gases is frequently necessary for quality control purposes. For most manufacturing processes, product quality depends on the concentration of particles above a specific threshold size. This paper will describe how to design an online nanoparticle monitoring system (NMS) for reactive (and inert) process gases from commercially available components, and will discuss how to adapt this system to varying process requirements, such as particle threshold size, and type and pressure of process gas. This paper will also describe a method to determine experimentally the performance of an NMS to ensure quality control.
