Abstract:
Introduction: Middle meatotomy is an effective surgical technique in the management of chronic sinusitis rebels to medical treatment. It is an optimal therapeutic option in the face of a chronic sinusitis particularly of rhinological origin. Patients and method: It is a descriptive retrospective study over an 11-year period from January 2009 to December 2019 at the service of Otolaryngology and Cervico-facial surgery (ORL-CCF) at the Andohatapenaka University Hospital Antananarivo Madagascar. Our study includes subjects who have benefited from an average meatotomy on chronic sinusitis. Results: We collected 320 patients of average age of 33.78 years. Repetitive maxillary sinusitis and rhinogenic allergies are the determinants of chronic sinusitis. Nasal obstruction was the constant functional sign and anterior rhinoscopy revealed a red nasal mucosa with enlarged inferior turbinate. All of our patients received an incidence X-ray of Blondeau. The average meatotomy was achieved in all our patients and among them, a proportion of 12.50% of the cases operated at the same time of a medium meatotomy and opening of other meatus. Complementary turbinal surgery was used in 25% of cases. Therapeutic efficacy was assessed subjectively by the subject’s functional signs. Favourable trends were reported in 75.30% of cases. Conclusion: Chronic sinusitis is a naso-sinus condition requiring medical-surgical management. The middle meatotomy is the first step in the surgical management of chronic rhinological sinusitis rebellious to medical means.

Abstract:
OBJECTIVE: The objective of this presentation is to display a series of new anatomical concepts and terms regarding the frontal si- nus, its drainage pathway and cells vs. spaces of the anterior ethmoid, based on Three-Dimensional Computer X-ray Tomography Stereoscopic Imaging (3DCTSI) and contrast these concepts to those reported in the current literature. METHODS: Given the new anatomic observations provided by 3DCTSI, and the widespread anatomic variations a small sample was initially selected to describe our observations. Six exemplary cases according to the “Classification of Fronto-Ethmoidal cells” by Kuhn, Bent et al., Lee et al., expanded by Wormald et al., and adopted by Ramakrishnan et al., Huang et al., and Void et al. (1-7) were chosen to illustrate our detailed anatomic observations. Additional observations and data of prevalence identified in a larger series will follow. RESULTS and CONCLUSION: Conceptually, the anterior ethmoid “cells” are in essence “spaces” with openings that communicate with the middle meatus and/or the ethmoidal infundibulum. The frontal sinus and frontal recess are a united and continuous three-dimensional, irregularly shaped space, the Frontal Sinus/Recess Space (FSRS). The uncinate process has two segments: the Ethmoidal Uncinate Process (EUP), which encompasses the Infundibular Space of the EUP (IS-EUP), currently known as the Agger Nasi cell; and the Turbinal Uncinate Process (TUP), which borders the Turbinal Infundibulum (TI) medially. The superior attach- ment of the EUP will be detailed in each of the six cases (Table 2). The middle meatus and infundibular passages are the drainage pathways from the frontal sinus and maxillary sinus to the nasal cavity.

The purpose of my research is to use the small wind-turbine as an auxiliary power source for the harshly limited space for living in Taiwan. From the practical point of view, I probe the possibility of installation of small wind-turbine, which bases on the cases studies and the data simulation, furthermore, discuss the influence by installing on the buildings, and the responsive strategy from the Building Codes. My conclusions are as follows: 1. The small wind-turbine models are recommended. Specifications of device is the diameter of blade shorter than 4M, e.g. the rotor swept area is smaller than 12.57㎡. Such products can support the current market demand for the 4KW or lower-output models. 2.The small wind-turbine can be used as an auxiliary power source The efficiency of wind-tubine which mostly depends on the velocity and veer of wind makes the output-power unstable. Such unstable output-power is unavailable for main power supply, but can be used as an auxiliary device to cost down the spending in electrical bills. 3.The installation of small wind-turbine should apply for the installation-permission. The installation of device on the building is involved with the safety of installation, the ownership of property and the safety of building structure. According to the Building Codes, it is considered as a kind of miscellaneous constructions, and need to apply for permission before starts installation. 4. Building Codes should be revised for the increasing demand for the small wind-turbine. No any Articles on the installation of small wind-turbine can be found in the announced Building Codes till now. A revision of Building Codes should be taken, not only to prevent from disputing and conflicting, as the amount of installed devices grows up in future, but to establish the installation standards for small wind-turbine. 5.A long-term local weather record is necessary to plan the installation of small wind-turbine. Even the small wind-turbine is an auxiliary power source, the device’s efficiency can be fully worked out by choosing the installing location and device model carefully. A better guideline for installation originates from the database of long-term local micro-weather records.

Abstract:
The reported problem is the failure of the middle bearing in an aircraft rotor engine. Tip-timing and tip-clearance and variance analyses are carried out on a compressor rotor blade in the seventh stage above the middle bearing. The experimental analyses concern both an aircraft engine with a middle bearing in good working order and an engine with a damaged middle bearing. A numerical analysis of the seventh stage blade free vibration are conducted to explain the experimental results. This appears to be an effective method of predicting middle bearing failure. The blade vibration variance increases when there is bearing failure.

Abstract:
This paper researches the steam cooling performance applied in ultra-supercritical steam turbines. The inlet main steam temperature of the middle pressure cylinder is the same or higher than that of the inlet main steam of the high pressure cylinder due to the reheated technology used in the ultra-supercritical steam turbines. The steam cooling design is used to decrease the thermal fatigue and high temperature creep of the rotor in high temperature operation environments for the ultra-supercritical steam turbines. The conjugation flow and heat transfer method was applied to investigate the cooling characteristics of the first two stages solid parts including the rotor blade, wheel disc and rotor blade root of the middle pressure cylinder. In addition, the influences of the cooling steam on aerodynamic performance parameters distribution of the first two stages were also analyzed by comparison of the through flow calculations without steam cooling. The results show that the steam cooling design can effectively cool the rotor system of the first stage, and the temperature of the solid part near the cooling hole decreases by up to 30K. The temperature of the steam flowing through the diaphragm seal of the second stage increases and is higher than that of the local main flow. Therefore, the temperature of the rotor system of the second stage is relative high. Furthermore, the cooling steam enters into the through flow passage and mixes with the main flow. This flow behavior leads to changes of the flow pattern and aerodynamic parameters distribution near the blade hub regions.

Abstract:
This work concerns an experimental study of pressure drop and heat transfer for turbulent flow inside a U-duct with relevance for tip cooling of gas turbine blades. The U-duct models the internal blade cooling flow passages. Both friction factors and convective heat transfer coefficients were measured along the bend (turn) part of the U-duct for three different rib configuration cases, namely (a) single rib at three different rib positions, i.e., inlet, middle and outlet, (b) two ribs with three different configurations, i.e., at the inlet and middle, at the middle and outlet as well as at the inlet and outlet, and (c) three ribs. The rib height-to-hydraulic diameter ratio, e/Dh, was 0.1 and the pitch ratios were 10 and 20. The Reynolds number was varied from 8,000 to 20,000. The test rig has been built in such a way that various experimental setups can be handled as the bend (turn) part of the U-duct can easily be removed and the rib configurations can be changed. The surface temperature was measured by using a high-resolution measurement technique based on narrow band thermochromic liquid crystals (TLC R35C5W) and a CCD camera placed facing the bend (turn) part of the U-duct. The calibration of the TLC is based on the hue-based color decomposition system using an in-house designed calibration box. Both the friction factor and heat transfer coefficient were affected by the position and configuration of the ribs along the bend wall. The highest friction factor was found for two ribs placed at the middle and outlet positions of the bend wall, respectively. The highest heat transfer coefficient was found for two ribs placed at the inlet and middle positions of the bend wall, respectively. The uncertainties in the experiments were estimated to be 3% and 6% for the Nusselt number and friction factor, respectively.
