Résumé :

In order to address the common difficulties in pulling and harvesting whole cotton stalks, such as high pulling resistance, high miss-pulling rate, and high breakage rate, which severely hinder the recycling of cotton stalks, three different pulling mechanisms with different pulling principles (wrapping-type pulling mechanism, clamping-type pulling mechanism, transverse roller-type pulling mechanism) were designed. The pulling force on cotton stalks during the pulling process of the three different roller-type pulling mechanisms was compared and analyzed, clarifying the mechanism of roller-typ

Résumé :

Abstract Muscular strength data associated with pushing and pulling forces are crucial for ergonomists to design tasks and equipment in manual materials handling. Usually, ergonomists measure pushing and pulling forces using a force gauge. Subjects participating in the pushing and pulling experiments need to grip and hold the force gauge. Additional weight from the force gauge can affect the muscular strength of the subjects, which impacts the validity and reliability of the pushing and pulling data. However, research on the design and fabrication of test rigs for facilitating pushing and pull

Abstract The string-pulling test is a classic test of physical cognition which is thought to examine an animal’s understanding of means-end comprehension, but may also result from trial and error learning. Here, we presented Green-winged macaws (Ara chloroptera) with a standard pull-up, and an alternative, pull-down, string pulling test to better understand the processes involved. Birds were divided into two groups: the experimental group were presented with the classic pull-up test and, upon completion, with the pull-down test, while the control group were only presented with the pull-down te

A bond pull test is used to determine the strength of the bond of an electronic interconnect to a circuit board. A standard test consists of clamping and pulling the interconnect with a pair of microscopic jaws. In a successful test, the maximum pulling force registered by the jaws will be the failure load of the interconnect to circuit board bond. However, if the interconnect itself deforms before the bond has failed, then this would constitute an unsuccessful test.

Résumé :

The aim of this thesis is to develop indirect and non-invasive methodologies for the tree root distribution analysis, with a multidisciplinary approach. Slope stability study needs the quantification of the root distribution. Current techniques carries out direct measurements on the root system by digging, uprooting and other invasive, non-replicable and onerous techniques. The methodologies, applied in this study, come from geophysics (I) and biomechanics (II). With the first approach, the geoelectric method is applied, in order to quantify the soil resistivity, in relation to water content.

Résumé :

Back, now, to Ipswich in 1568 — and to a disorientingly dual narrative in which the darker side of shared creaturely vulnerability is hidden, though ever-present, beneath a story of human victory over the monstrous. As we have seen, the strong surface current running through Timothy Granger’s broadside account of the capture of twenty-seven orca concentrates its definition of monstrousness on the size of the captured creatures. Unlike other monster broadsides of its day, it is without an explicit moral: the monsters are used neither to warn against behaviors that cross culturally constructed moral boundaries nor to plead with readers to reform their lives. It is a story of human ascendency. But pulling strongly in the other direc-tion — back to sea, back to the enormity of non-human otherness and to the disturbing darkness of unspeakable human cruelty — the broadside also illustrates the extreme brutality of the men of Ipswich upon encountering their “monsters.” The orca, once finally captured, were hauled in to Ipswich wharf; the largest was tied to a tree. “Som of them,” we learn, “laye upon the wharfe .ii. dayes and a nyght before they weare dead, and yet [the men] strooke them wyth Axes & other weapons to kyll them,” even to the point of their axes breaking on the whales’ “bones hard as stones.” While Granger never remarks upon the merciless brutality he describes at length, it saturates the text. It is likely that these actions were legible as cruelty to many contemporaries, especially those who focused on the creatures as fish first and monsters second.

Résumé :

Covers the rise of Ronald Reagan and a more conservative, individualistic approach to government and society that would have far-reaching effects on Charlotte schools.Explores persisting obstacles to racial advancement, including shifts in job markets, housing patterns and political priorities that perpetuated income and homeownership gaps into the 1980s and 1990s, and sharpened distinctions between struggling central-city neighborhoods and increasingly prosperous suburban communities. Traces the national shift in education priorities from promoting integration to a concern with test scores and an interest in "choice," which led Charlotte's business leaders to promote a desegregation plan focused around magnet schools instead of race-based busing. Examines growing concerns about the performance of African American students in desegregated schools, and about the challenges faced by young black men in urban neighborhoods. Follows the Capacchione lawsuit, which challenged the use of race in student assignment and brought an end to Charlotte's busing plan.

Abstract A continuing problem with coatings applied to sharp edges of a structure is the corrosion that often develops at the apex of the edge. The conventional wisdom is that the reduction of film thickness, due to coating pulling away at the edge during the curing of the coating, is the primary cause for the onset of corrosion. This theory, however, is not necessarily correct, both from a mechanistic and practical point of view. This discussion paper will present the conventional viewpoint of what is called “edge retention” or “edge coverage” and why it is insufficient in describing corrosio

Abstract An advanced jarring method was developed for deviated wells where conventional jarring is not possible. Comparing the results of jarring impact with this new method to jarring impact with conventional methods showed similar effectiveness.

Résumé :

The present study is aimed at investigating the effect of solder mask thickness on the solder ball shear test. Compared to the ball pull test, less brittle failures were found in the ball shear test. This is most likely caused by the support of solder mask. So far there is not publication reporting the effect of solder mask in detail. In this paper, specimens with various thicknesses of solder mask were fabricated and a series of ball shear tests were conducted. Cold ball pull (CBP) tests were performed as well for parallel studies. The attachment strength of solder balls under multiple reflow

Résumé :

Abstract The split-sleeve cold expansion process enhances the durability of metallic structures by imparting deep compressive residual stresses around fastener holes to extend the fatigue lives of the fastened structures. This study aims to improve the accuracy of the pulling force estimation by establishing the variable friction model of the dry-lubricated split sleeve when cold working an aluminum 2024-T3 hole. The variable friction model was empirically obtained from the friction experimental setup simplified from the split-sleeve cold expansion process. The contact-pressure-dependent varia

Résumé :

In atomic force microscopy (AFM) -based single molecule force spectroscopy, it is assumed that the pulling angle is negligible and that the force applied to the molecule is equivalent to the force measured by the instrument. Although this assumption may hold for flexible, compact molecules, studies have shown that it may not be appropriate for fairly rigid molecules, where measured forces can be a fraction of the actual values experienced by the molecule. Previously, we have proposed a method to align a molecule’s substrate and cantilever attachment sites and tested it in a simulated environme

medicine, industry, and biotechnology. Fungi produce a wide range of bioactive compounds, such as alkaloids, antibiotics, antifungals, immunomodulators, anticancer agents, enzymes, and vitamins. However, these compounds are often locked inside the fungal cell wall, which is composed of chitin, a tough substance that is dif�icult to digest by humans1. Therefore, it is essential to have a good extraction technique that can break down the chitin and release the valuable compounds from the fungi, this is especially essential in the laboratory for accurate lab assays and potency determination durin
