Fresh Air Exchange Method Research of Residential House Based on Natural Ventilation Peizhe Tian1,a, Fuxiang Chen1,b, Wei Pi1,c 1Biochemical Engineering College, Beijing Union University, Beijing 100020, China ajdtpeizhe@buu.edu.cn, bjdtfuxiang@buu.edu.cn, cjdtpiwei@buu.edu.cn Keywords: Natural ventilation, Indoor air quality, Residential house, Unpowered components Abstract.
The fresh air exchange component is designed based on the theory of natural ventilation, consisting of dust filter materials and valves.
Moreover, it boasts low noise and no pollution and uses PVC materials, galvanized steel sheets or corrosion resistant plates.
Meanwhile, since the fresh air exchange components are unpowered and boast low costs of installation and use, it is an effective way to ensure the ventilation and prevent sands and dust from entering into the room, thus playing a key role in improving the indoor air quality and reducing the energy consumption of buildings.

Adverse Event Management Tool for Hospitals: A Game-Changer for Patient Safety Reyna Valle1,a*, Gabriela Cribas1,b and Ana Laura Ramírez1,c 1Faculty of Engineering, Universidad Tecnológica Centroamericana, San Pedro Sula, Honduras aelizabeth.vallenitec.edu, bgcribas@unitec.edu, canaramirezs2610@unitec.edu Keywords: Adverse event, failures, medical device, technology surveillance.
Approximately 15 nurses per hospital were interviewed, selected from areas with the most patient contact, as well as the responsible biomedical engineers.
Therefore, only the head nurses of each hospital ward, two nurses per ward, and the biomedical engineers within each healthcare institution were included.
In the healthcare sector, there is a tendency towards corrective rather than preventive measures, with emphasis on corrective maintenance due to workload, staff shortages, lack of materials and supplies, and budget constraints.
Fig. 5 shows a usage test from the perspective of a biomedical engineer, who would be responsible for managing and using the bot's settings [29].

Early-stage oxidation behavior of γγγγ''''-Ni3Al-based alloys with and without Pt addition Shigenari Hayashi1,a, Toshio Narita 1,b and Brian Gleeson2,c 1 Devision of Materials Science and Engineering, Hokkaido University, N13, W8, Kitaku, Sapporo, 060-8628, Japan 2 Department of Materials Science and Engineering, Iowa State University, Ames, Iowa, 50011-2300, USA a hayashi@eng.hokudai.ac.jp, bnarita@eng.hokudai.ac.jp, cbgleeson@iastate.edu Keywords: short-term oxidation, γ'-Ni3Al, Pt effect, Al2O3 scale, GD-OES analysis Abstract The early-stage oxidation behavior of γ'-Ni3Al-based alloys of composition (in at.%) Ni-22Al and Ni-22Al with 10, 20, and 30Pt was investigated in terms of oxidation kinetics, scale evolution and resulting composition profiles during heating to 1150ºC in air.
Several mechanisms have been proposed for this beneficial effect, including the postulation that Pt reduces both the negative effect of impurity sulfur and the extent of void formation at the oxide / alloy interface [5,6], or that the presence of Pt leads to the development of alloy protrusions into the oxide scale, which act to "key" the scale to the coating or alloy [7].

Moreover, the absence of PVP in E solution was a key factor for the formation of larger Ru nanoparticles in our seed-mediated method. 2.

The cultivated land, once damaged, need to invest huge human, material and financial resources to restore its agricultural productivity.
On the basis of strengthening the construction of engineering facilities, but also should be strengthened the construction of non-engineering measures: Cultivated land damaged by flood risk evaluation system is established and the effects of it have a certain predictability, the mechanism of monitoring and predicting of land and should be strengthened.
Combining with engineering measures and non-engineering measures, preventing the happening of flooding disasters, reducing the flooding disasters on cultivated land, which could protect the cultivated land resources and ensure the safety of food effectively.
The evaluation method is not only fully considering the mechanism of healed cooperation to each evaluation factor, also considering the restriction of key factor.

These standards with referenced documents provide comprehensive information which include materials specification, design procedures, constructions essential and testing methods.
The testing methods which include both for materials and the composite slabs system itself are used to evaluate the performance for application in the construction industries.
Experimental Program Material Description and Samples Preparation.
This shows in the other part of the C-channel where plastic buckling did not occur, the materials still behave elastically and are not totally deform by the failure load application.
More area will be encompassed in the tensile stress which has made the steel decks be more effective as ductile materials for the structure system.

Introduction Detecting damage in a structure by monitoring has been an important task throughout the literature devoted to aerospace, mechanical and civil engineering.
A physical parameter as the plate thickness or the material properties of an specific element can be chosen as updating variable, therefore, the engineer can analyze easily the credibility of the results.
The key point is that the analysis set does not include the clamped nodes.
