This investigation was undertaken to find a method of modifying ailerons so that a machine may be more responsive in roll.

This paper aims to research the corrosion behavior of the metal under the disbonded coatings interfered with AC through electrochemical method.

The corrosion behavior of the metal under disbond coating interfered with alternate stray current (AC) was studied by electrochemical methods using the rectangular coating disbonded simulator. The obtained data from electrode potential test, electrochemical impedance spectroscopy (EIS) and polarization curves in simulated soil solution indicated that under the natural corrosion condition, the self-corrosion potential and the corrosion current density of the metal at different depths under disbond coating had obviously changed if there was AC interference.

The self-corrosion potential of the metal at the same depths under disbond coating shifted negatively with the rising of the AC voltage. Under the condition of cathode polarization, there was still obvious potential gradient with the extension of the deep peeling of the coating gap, and the corrosion current density of the test points was minimum, and the protection effect was best when the cathode protection potential was −1.0 V. When the metal was applied with over-protection, the corrosion rate of the metal increased as AC stray current flowing through it increased.

This paper used the rectangular aperture device to study the corrosion behavior of X80 steel under the disbonded coatings through electrochemical methods when the AC stray current interference voltage was 0V, 1V, 5V or 10V and the protection potential was 0V, −0.9V, −1.0V, −1.2V or −1.3V, respectively. There is great significance to the safe operation and long-term service of pipeline steel in soil environment.

IN recent issues we have had contributionsion the future of Work Study as seen by Council members of the Institute of Industrial Technicians, the Society of Industrial Engineers and the Work Study Society.

The largest Walking Dragline in the world has presented almost every branch of engineering with some difficult problems, but as most readers will know, this monumental machine was completed last year to the order of Messrs. Stewarts and Lloyds by Messrs. Ransomes & Rapier Ltd., Ipswich. It was constructed in their works and erected on site at Northamptonshire, where it is engaged on stripping iron ore.

Montreal, October 1982 — Two recent potentially disastrous occurrences on international air routes near the site of volcanic eruptions have shown the need for new procedures to warn pilots against the danger of volcanic ash.

This paper aims to investigate the delamination wear properties of a carbon strip in a carbon strip rubbing against a copper wire at the high-sliding speed (380 km/h) with or without electrical current.

The friction and wear properties of a carbon strip in a carbon strip rubbing against a copper wire are tested on the high-speed wear tester whose speed can reach up to 400 km/h. The test data have been collected by the high-speed data collector. The worn surfaces of the carbon strip are observed by the scanning electron microscope.

It was found that there was a significant increase of the delamination wear with the decrease of the normal load when the electric current is applied. The size of the flake-like peeling also increases with the decrease of normal load. The delamination wear extends gradually from the edge of the erosion pits to the surrounding area with the decrease of the normal load. However, the delamination wear never appears in the absence of electric current. It is proposed that the decreased normal load and the big electrical current are the major causes of the delamination wear of the carbon strip.

The experimental test at high-sliding speed of 380 km/h was performed for the first time, and the major cause of the delamination was discovered in this paper.

This paper reports on an integrated prototype expert system, which has been developed to support geotechnical engineers during the initial foundation design phase. Foundation design based on Dutch practice and geotechnical codes as well as construction and project management aspects is programmed. The paper discusses an integrated approach to foundation design of buildings using a case‐demonstration to show the proposed system and its basis. The modelling techniques used offer a sound basis for including these aspects in routine geotechnical design. The example has indicated that the system is capable of integrating geotechnical design aspects with construction related aspects in order to produce better foundation design solutions.

In the face of the COVID-19 pandemic, many countries, including Palestine, implemented lockdown rules. These measures slowed the outbreak of the coronavirus, and because of the poor management of the Palestinian government in dealing with women’s rights in light of the Corona pandemic, they contributed to increasing gender-based violence (GBV).

The study used the qualitative method. An inductive thematic latent content analysis was applied using the MAXQDA 2020 program throughout the data collection stage. The content analysis in this study focused on interviews made with the survivors. The interview schedule consisted of four questions covering different aspects of knowledge around GBV during COVID-19 in the Gaza Strip. In-depth interviews were conducted in Arabic with 25 survivors who experienced GBV between January 17 and March 13, 2022.

The results show that the kind of violence the survivors were most subjected to is psychological violence, followed by economic violence, and the least kind of violence that the survivors were subjected to was sexual violence. The study revealed the good practices for preventing and combating violence against Palestinian women and girls due to government measures to reduce COVID-19 from the perspective of survivors.

One of the limitations of this study was the small number of cases coming to the Aisha Association for support. Because of the temporary suspension of psychological and social support projects from the foundation due to a problem related to funding, some survivors also fear that their husbands will discover that they have participated in the study, so they hesitate to agree to an interview. Survivors’ lack of understanding of the study question related to implications of closing social justice institutions due to COVID-19 on GBV? This led to conflicting answers.

To the best of the authors’ knowledge, it is the first study in Palestine that dealt Consequences of Government Measures in Palestine to Mitigate COVID-19 on GBV, and its results will be important for the protection of survivors and the adoption of government policies in Palestine.
