Drive Axle

The proposed system's basic premise is to reduce personnel during nut fitting and removing wheels from autos. The motor is at the heart of the project and its implementation. Motor, Nut fitting arrangement (multi nut remover), and spur gear arrangement are the components employed here for the efficient operation of separate blocks. The model's main goal is to remove all of a wheel's nuts at once, rather than one by one. The model's premise is to use a spur gear to transfer relative motion to other gears. The primary spur gear is connected to the motor shaft in the model, which rotates due to the motor. The primary gear is the driver, while the secondary gears are the driven. The major gear is located in the model's center. The secondary gears and the primary gear are in sync. To ensure precise meshing and tool spacing, the secondary gears are set at predetermined distances. The drive axle is equipped with primary gear. The cover has several auxiliary axles that extend through it. Each secondary axle has a first end that is positioned inside the housing and a second end that extends outwardly from the cover. One of the first ends is attached to each of several secondary gears. Each of the secondary gears is in contact with the primary gear. One of the secondary axles is connected to each of the couplers. The project and implementation must provide the motor with both positive and negative potential. If we press the corresponding switch for forwarding rotation, the nut will be fixed; if we press the corresponding switch for reverse rotation, the polarity will be reversed, and the nut will be removed. The motor can be controlled according to the needs of the operator. To tighten or remove the nut, the operator should lift the model and place it in the proper location.

We have investigated the feasibility of restoring blurred electron micrographs. Two related problems have been considered; the restoration of images blurred as a result of relative motion between the specimen and the image plane, and the restoration of images which are rotationally blurred about an axis. Micrographs taken while the specimen is drifting result in images which are blurred in the direction of motion. An example of rotational blurring arises in micrographs of thin sections of helical particles viewed in cross section. The twist of the particle within the finite thickness of the section causes the image to appear rotationally blurred about the helical axis. As a result, structural details, particularly at large distances from the helical axis, will be obscured.

Abstract Energy loss per hour in a tire traveling at 80 km/h was obtained for a number of tires of different sizes and makes from the respective whole tire hysteresis loss of each tire. This loss value was then compared to the corresponding rolling loss obtained from the 1.7 m dynamometer rolling resistance method. The two methods agreed, indicating that the basic premise of the rolling resistance hysteresis ratio relation is valid.

Ethics Course

This paper was written based on part of the findings of a survey made on young lawyers who are practicing in the state of Kedah. Young lawyers are advocates and solicitors with less than seven y ears of active practice. The objective of this study is to determine what factors positively influenced young lawyers' ethical decision making. Data was collected from /33 young lawyers who are practicing in the state of Kedah between January - June 2006 through self-administered and close- end questionnaires. The finding suggests that knowledge in professional legal ethics gained at the law faculty, pupil age and short ethics course does not contribute much to the ethical decision making of the young lawyers. Moved by this finding. this paper attempts to discuss the current legal ethics education in Malaysia. The main contention of the writers is their firm belief that the current practice of professional legal ethics education in Malaysia is insufficient and far from being adequate in producing ethical lawyers. Therefore the writers have proposed for professional legal ethics education in Malaysia to be reformed and this proposal serves as the basic premise of this paper.

Subject. The article updates the scientific view of the environmental protection greening and the special land use regime as a special city planning means of passive sanitary protection of people from the adverse aerial and technological impact and the recovery of the environment we live in. Objectives. I identify the specifics of designing and efficient operation of environmental protection greening as an inseparable part of the urban ecosystem. The article justifies the technique for strategic positioning of respective infrastructure projects in order to ensure the protective effect. Methods. The study relies upon general methods of analysis, systematization of existing viewpoints and published findings, graphic and logic analysis, matrix-based tools to choose an administrative strategy. Results. I analyzed the air-holding capacity of economic activity in regions and the outcome of air quality monitoring as a risk factor for public health. The article pinpoints operational difficulties in the environmental protection greening facilities and strategic approaches to addressing the issues in order to improve the environmental security of industrial zones. I determine new aspects of public relations and groups of criteria to assess the effectiveness of green infrastructure projects. The article provides the rationale for fiscal incentives for investors and public-private partnership of stakeholders. Conclusions and Relevance. Considering national projects, such as Ecology, Demography, Convenient Urban Environment, I emphasize the relevance of recovering and rehabilitating obsolete environmental protection greening facilities situated in industrial zones of industrially developed cities. Green projects should indeed comply with a set of progressive results of fundamental studies carried in various scientific areas. There should be fiscal incentives in terms of taxes and depreciation on special assets as the basis for the private-municipal partnership in green assets management in order to enhance the environmental security of industrial zones.
