Abstract Foreign material extractors were installed and evaluated in farmers stock peanut flowpipes during the harvest seasons of 1978, 1979, and 1980. Three of the extractors evaluated were commercially available and consisted of a stationary, inclined screen manufactured by Suffolk Iron Works, Inc., Suffolk, VA; an inclined, mechanical tumbler-extractor manufactured by Hobbs-Adams Engineering Company, Suffolk, VA; and an inclined, mechanical roller screen manufactured by Bev. Mathison's Spring Works, Warwick, Queensland, Australia. Two additional experimental extractors including a stationary, inclined screen and an aspirator were also tested along with aspiration hoods used in conjunction with the commercial extractors. The weight per tonne (t) of peanuts of foreign materials removed by the various extractors ranged from 0.8 kg to 21.3 kg. Aspiration generally doubled the amount of foreign materials removed by the extractors. The primary materials removed by the extractors were dirt, peanut stems, sticks, leaves, small rocks, and some broken or loose shelled peanut meats.

Abstract In this paper, we carried out PIND (Particle Impact Noise Detection) test and X-ray inspection of a transistor in a TO-18 package for commercial and industrial applications. From our evaluation results, we explain the validity of the PIND test by comparing PIND test and X-ray inspection results. We make clear that PIND test is able to detect internal foreign material that may be transparent to X-ray inspection. In addition, we report analysis results of internal foreign materials from defective devices. This matter suggests that a problem is contamination control in the manufacturing process, most likely the sealing process.

When in contact with blood, some materials cause relatively little alteration in the natural properties of the blood, while others rapidly cause the formation of a clot. Thus understanding how blood reacts with foreign materials has both scientific importance, in understanding the details of clotting mechanisms, and practical consequences, in materials selection for prosthetic applications. It has been observed that the layer adsorbed on all synthetic materials in contact with blood appears to be the same by all techniques thus far utilized, no matter whether the material is bio-compatible or causes clotting. In order to attack this paradox, we have initiated a study of the morphology of the early stages of the interaction of blood with a foreign material, amorphous carbon, that is both convenient for electron microscopy and is an important prosthetic material.

Abstract The identification of foreign material at metal-oxide interface or at the poly-substrate interface by means energy dispersive spectroscopy (EDS) is very difficult. Auger depth profiling can be used as an alternative method to cross-section EDS analysis for the identification of very thin layers of foreign material in semiconductor devices. This article presents a sample preparation method adapted from a planar transmission electron microscopy sample preparation method so that Auger depth profiling can be used as a practical tool for identifying very thin layers of foreign materials at interfaces buried deep within semiconductor devices. The discussion covers the advantages, applications, and the procedure for performing the analysis. The high degree of control provided by the method gives an analyst the ability to easily thin down material layers to less than 100nm of a target layer, thereby significantly reducing sample preparation time as well as analysis time on the Auger tool.

Careful History

While the majority of fistulas in ano result from infection of the anal crypts, complex, recurrent, and/or nonhealing fistulas should always raise the suspicion of a chronic underlying condition. In this paper, we present a 30-year-old male patient with a diagnosis of a complex suprasphincteric fistula caused by a surgical thread left behind after an orthopedic hip operation performed sixteen years ago. Partial fistulectomy, extraction of the foreign material, and debridement procedures were performed. Few cases of such complex fistulas in ano due to foreign materials have been described in the literature. After careful history-taking, meticulous physical examination under general anesthesia should be done in order to deal with this rare type of fistula.

Ingestion of abnormal materials by cetaceans has been reported worldwide, but few studies have investigated the causes of foreign material ingestion. We retrospectively analysed necropsies performed between 2012 and 2019 on 88 cetaceans stranded along the coast of Catalonia, Spain, and evaluated the association of abnormal ingested materials with 2 risk factors, namely disease of the central nervous system (CNS) and maternal separation. Abnormal materials were found in the digestive tract in 19 of 88 (21.6%) cetaceans; of these, 13 (60%) had lesions in the CNS, such as morbilliviral encephalitis, neurobrucellosis or encephalomalacia, and 3 were diagnosed as having experienced maternal separation. In a logistic regression model, CNS lesions and maternal separation were identified as risk factors for ingestion of foreign material, but with wide confidence intervals, probably due to the small sample size. In contrast, abnormal ingestion was not identified in any of the 25 (28%) cetaceans whose cause of death was attributed to interaction with humans. Abnormal ingestion should be interpreted with caution, and efforts should be made at necropsy to exclude CNS diseases through pathologic and microbiologic investigations. If disease of the CNS is a significant risk factor for ingestion of marine debris by small odontocetes, results of monitoring programmes may be biased by the prevalence of CNS disease in a specific area or population.

Automotive Finish

Coatings are applied to appliances, instruments and automobiles for a variety of reasons including corrosion protection and enhancement of market value. Automobile finishes are a highly complex blend of polymeric materials which have a definite impact on the eventual ability of a car to sell. Consumers report that the gloss of the finish is one of the major items they look for in an automobile.With the finish being such an important part of the automobile, there is a zero tolerance for paint defects by auto assembly plant management. Owing to the increased complexity of the paint matrix and its inability to be “forgiving” when foreign materials are introduced into a newly applied finish, the analysis of paint defects has taken on unparalleled importance. Scanning electron microscopy with its attendant x-ray analysis capability is the premier method of examining defects and attempting to identify their root cause.Defects are normally examined by cutting out a coupon sized portion of the autobody and viewing in an SEM at various angles.

The South African workplace is confronted with many leadership challenges, specifically those relating to the employment relationship between subordinates and their supervisors. A high-quality relationship is essential, considering the work-family spillovers employees experience. Limited research has been conducted on the potential positive and negative consequences of the leader-member exchange (LMX) dyadic relationship. In this study, we used a cross-sectional research design, and drew an employee sample (N = 120) from a commuter transport engineering company. A five-point Likert scale was employed and statistical analyses were carried out using the SAS statistical program. We calculated Pearson correlation coefficients and used structural equation modelling to test the proposed conceptual model to indicate possible correlations between the different variables. The main finding of the study was that the nature of the LMX relationship quality in the relevant company appeared to be high and positively related to work-home enrichment but negatively related to work-home conflict and role overload. The article concludes by making a number of suggestions to respond to challenges.
