Environment Pollution
Abstract

Recent developments in the field of mass spectrometry taking place at the Caltech Jet Propulsion Laboratory are highlighted. The pertinent research and development is aimed at producing an ultrahigh sensitivity mass spectrograph for both spaceflight and terrestrial applications. The unique aspect of the JPL developed technology is an integrating focal plane ion detector that obviates the need for spectral scanning since all ions over a wide mass range are monitored simultaneously. The ion detector utilizes electro-optical technology and is therefore referred to as an Electro-Optical Ion Detector (EOID). A technical description of the JPL MS/EOID, some of the current applications, and its potential benefits for internal contamination analysis are discussed.

Abstract

The minimum scientific spacecraft instrumentation is considered that is likely to result in as complete an understanding of the composition, structure, and activity of a cometary nucleus as is possible without landing on it. The payload will also give useful results on secondary goals of a better understanding of physical processes in the inner and outer coma. Studies of composition, by means of an actual landing on the surface, details of the internal structure of the nucleus, and sample return were considered beyond the scope of this mission.

Abstract

A mass spectrometer (MS) with unique magnetic pole pieces which provide a homogenous magnetic field across the gap of the MS magnetic sector as well as the magnetic field across an ion-type vacuum pump is disclosed. The pole pieces form the top and bottom sides of a housing. The housing is positioned so that portions of the pole pieces form part of the magnetic sector with the space between them defining the gap region of the magnetic sector, through which an ion beam passes. The pole pieces extend beyond the magnetic sector with the space between them being large enough to accommodate the electrical parts of an ion-type vacuum pump. The pole pieces which provide the magnetic field for the pump, together with the housing form the vacuum pump enclosure or housing.

Abstract

The design and fabrication of a completely portable, self-contained gas chromatograph is described. This instrument utilizes a closed-loop hydrogen carrier gas flow as maintained by a hydrogen generator-separator. It employs an auxiliary hydrogen generator to keep a positive flow of hydrogen through the detector. The detector is an ionization cross section detector. The only maintenance required is the addition of water (5-15 cc/day) to the auxiliary hydrogen generator. Lower limit of detection for the present system is of the order of 1-10 ppm ethane.

Abstract

Background: Educating future physicians about sexual and gender minority (SGM) patients and their health care needs is an important way to mitigate discrimination and health disparities faced by this community. Canada, across its 17 medical schools, lacks a national standard for teaching this essential topic. This paper aims to review the best practices for teaching an SGM curriculum in undergraduate medical education and synthesize this information into actionable propositions for curriculum development., Methods: A scoping literature review was conducted to identify best practices for SGM teaching. The review elicited peer-reviewed and grey literature on best practices for SGM teaching, policy documents, and opinion pieces from medical education authorities and SGM advocacy groups. Through an iterative process with all authors, the Canadian Queer Medical Students Association (CQMSA), and the Association of Faculties of Medicine of Canada (AFMC), a set of propositions was developed., Results: The search yielded 1347 papers, of which 89 were kept for data extraction. The main outcomes of these papers were sorted along five repeating themes, which formed the basis for six propositions; two more propositions were then added after discussion with all authors., Conclusion: We present eight propositions for the development of a national standard for SGM education at the undergraduate medical level. These include standardizing learning objectives across all schools, using established curricular models to guide curriculum development, interweaving concepts across all levels of training, diversifying teaching modalities, providing faculty training, ensuring a safe space for SGM students and faculty, using OSCEs as a teaching tool, and involving the local SGM community in curriculum development and delivery., Competing Interests: All authors have no financial or personal conflicts of interest to declare., (© 2024 Giffin, Glow, Lebo, Freeman, Miladinovic, Hansen, Brown, Karsenti; licensee Synergies Partners.)

33. An Actor's Knowledge and Intent Are More Important in Evaluating Moral Transgressions Than Conventional Transgressions.

Author

Abstract

An actor's mental states-whether she acted knowingly and with bad intentions-typically play an important role in evaluating the extent to which an action is wrong and in determining appropriate levels of punishment. In four experiments, we find that this role for knowledge and intent is significantly weaker when evaluating transgressions of conventional rules as opposed to moral rules. We also find that this attenuated role for knowledge and intent is partly due to the fact that conventional rules are judged to be more arbitrary than moral rules; whereas moral transgressions are associated with actions that are intrinsically wrong (e.g., hitting another person), conventional transgressions are associated with actions that are only contingently wrong (e.g., wearing pajamas to school, which is only wrong if it violates a dress code that could have been otherwise). Finally, we find that it is the perpetrator's belief about the arbitrary or non-arbitrary basis of the rule-not the reality-that drives this differential effect of knowledge and intent across types of transgressions., (Copyright © 2017 Cognitive Science Society, Inc.)

34. The explanatory effect of a label: Explanations with named categories are more satisfying.

Abstract

Can opium's tendency to induce sleep be explained by appeal to a "dormitive virtue"? If the label merely references the tendency being explained, the explanation seems vacuous. Yet the presence of a label could signal genuinely explanatory content concerning the (causal) basis for the property being explained. In Experiments 1 and 2, we find that explanations for a person's behavior that appeal to a named tendency or condition are indeed judged to be more satisfying than equivalent explanations that differ only in omitting the name. In Experiment 3, we find support for one proposal concerning what it is about a name that drives a boost in explanatory satisfaction: named categories lead people to draw an inference to the existence of a cause underlying the category, a cause that is responsible for the behavior being explained. Our findings have implications for theories of explanation and point to the central role of causation in explaining behavior., (Copyright © 2017 Elsevier B.V. All rights reserved.)

35. Wrong or merely prohibited: Special treatment of strict liability in intuitive moral judgment.

Abstract

Most crimes in America require that the defendant have mens rea, Latin for "guilty mind." However, mens rea is not legally required for strict liability crimes, such as speeding, for which someone is guilty even if ignorant or deceived about her speed. In 3 experiments involving participants responding to descriptive vignettes, we investigated whether the division of strict liability crimes in the law reflects an aspect of laypeople's intuitive moral cognition. Experiment 1 (N = 396; 236 male, 159 female, 1 other; M age = 30) found evidence that it does: ignorance and deception were less mitigating for strict liability crimes than for "mens rea" crimes. Experiments 2 (N = 413; 257 male, 154 female, 2 other; M age = 31) and 3 (N = 404; 183 male, 221 female, M age = 35) revealed that strict liability crimes are not treated as pure moral violations, but additionally as violations of convention. We found that for strict liability crimes, ratings of moral wrongness and punishment were influenced to a greater extent by the fact that a rule had been violated, even when harm was kept constant, mirroring the legal distinction of malum prohibitum (wrong as prohibited) versus malum in se (wrong in itself). Further, we found that rules prohibiting strict liability crimes were judged more arbitrary than corresponding rules for "mens rea" crimes, and that this judgment was related to the role of mental states. Jointly, the findings suggest a surprising correspondence between the law and laypeople's intuitive judgments. (PsycINFO Database Record, ((c) 2016 APA, all rights reserved).)

Abstract

Aims: The primary objective was to estimate prevalence of malnutrition on admission to four hospitals. Secondary objectives included assessing the relationship between nutritional status and length of hospital stay, numbers of new prescriptions, new infections and disease severity., Methods: We entered eligible patients according to predefined quotas for elective and emergency admissions to 23 specialties. We measured height, weight, Body Mass Index and anthropometrics, and recorded history of unintentional weight loss. Patients who had lost > or = 10% of their body weight, had a Body Mass Index <20, or had a Body Mass Index <20 with one anthropometric measurement <15th centile were considered malnourished., Results: Of 1611 eligible patients, 761 did not participate; 269 were too ill; 256 could not be weighed; and 236 refused consent. Eight hundred and fifty were subsequently evaluated. Prevalence of malnutrition on admission was 20%. Length of stay, new prescriptions and infections and disease severity were significantly higher in the malnourished., Conclusions: One patient in every five admitted to hospital is malnourished. Although this figure is unacceptably high, it may underestimate true prevalence. Malnutrition was associated with increased length of stay, new prescriptions and infections. Malnutrition may also have contributed to disease severity., (Copyright 2000 Harcourt Publishers Ltd.)

Abstract

Management of auricular hematomas has always been a challenge for physicians. This injury is very common among wrestlers since early olympic competition times. Initial treatment usually involves simple aspiration and a compression bandage. Most of these hematomas recur; then it must be decided how to manage this recurrent problem and the eventual "cauliflower ear." A treatment is proposed that directs attention to the pathophysiology of the injury and involves total excision of the newly formed fibroneocartilaginous layer. Unless this layer is successfully removed the hematoma will persist and a thickened ear will result. This treatment can be performed on an outpatient basis under local anesthesia and allows immediate resumption of wrestling competition.

38. Linear position-sensitive x-ray detector incorporating a self-scanning photodiode array.

Author

Gamble RC, Baldeschwieler JD, and Giffin CE

Abstract

A linear position-sensitive x-ray detector for x-ray spectroscopy and diffraction applications has been tested which can provide excellent spatial resolution, wide dynamic range and good sensitivity. The heart of the system is a self-scanning, photosensitive silicon diode array. It is interfaced via fiber optics to a thin layer of ZnS which fluoresces visible light upon absorption of x-radiation. The conversion to visible light and optical coupling provide several-fold gain in the efficiency of detection as compared to the direct detection of x-ray by the diode array. Equally important is that the array is protected from irreversible damage by high energy radiation, a limitation which previously hindered this application of silicon diode technology.

Abstract

A number of cell surface molecules of great theoretical and practical importance simply cannot be obtained in amounts sufficient for molecular analysis using conventional methods and instrumentation. Because of our interest in such studies, we began about eight years ago to explore the possibility of developing new instrumentation for the sequence analysis of very small quantities of polypeptide chains. These efforts have led to the development of two microsequenators which employ one thousandth to one ten-thousandth the material used in the original sequenator described by Per Edman. In addition, in conjunction with the explosion of recombinant DNA techniques, we also have begun to develop instrumentation for the sequence analysis and synthesis of DNA molecules. In this paper we describe briefly several new instruments that have been developed at Caltech. We believe this new instrumentation in conjunction with the recombinant DNA and hybridoma technologies will provide unique opportunities to analyze cell-surface molecule in the years ahead.

Abstract

The wrestler's ear (acute auricular hematoma) is a common problem for physicians treating facial trauma. One method of treatment involves open drainage of the serum and excision of the newly formed fibroneocartilage. This technique provides an outstanding cosmetic result and allows the athlete continued wrestling competition.
