Francis Bacon's natural history and the Senecan natural histories of early modern Europe.

Science.gov (United States)

Jalobeanu, Dana

2012-01-01

At various stages in his career, Francis Bacon claimed to have reformed and changed traditional natural history in such a way that his new "natural and experimental history" was unlike any of its ancient or humanist predecessors. Surprisingly, such claims have gone largely unquestioned in Baconian scholarship. Contextual readings of Bacon's natural history have compared it, so far, only with Plinian or humanist natural history. This paper investigates a different form of natural history, very popular among Bacon's contemporaries, but yet unexplored by contemporary students of Bacon's works. I have provisionally called this form of natural history'Senecan' natural history, partly because it took shape in the Neo-Stoic revival of the sixteenth-century, partly because it originates in a particular cosmographical reading of Seneca's Naturales quaestiones. I discuss in this paper two examples of Senecan natural history: the encyclopedic and cosmographical projects of Pierre de la Primaudaye (1546-1619) and Samuel Purchas (1577-1626). I highlight a number of similarities between these two projects and Francis Bacon's natural history, and argue that Senecan natural history forms an important aspect in the historical and philosophical background that needs to be taken into consideration if we want to understand the extent to which Bacon's project to reform natural history can be said to be new.

Full Text Available En el momento en que la imagen ofrecida no es la esperada, el arte permite que el hombre se interrogue sobre la veracidad del mundo que le rodea. Las crucifixiones de Bacon y Barceló, cuyas desquiciadas formas suplantan al Cristo crucificado, devuelven al ojo su facultad de ver, abren el interrogante acerca del resquebrajamiento del símbolo que representan: permiten que el hombre tome conciencia de su ubicación en la vida. No hay imagen, no hay rostro, que no señale la ausencia de Dios, que no apure la falsedad del sistema. Las crucifixiones de Bacon y Barceló activan esa falta, se hacen parte de ella; la traen al presente. El símbolo se abre al rostro ignorado del otro. La cruz es porosidad, carne. La pintura, materia. La imagen simbólica recupera su potencialidad con ellas.When the offered image isn't the expected, the art allows the man questioning himself over the world's veracity around him. The Bacon and Barceló's crucifixions, with deranged forms take the place of crucified Crhist, giving back to the eye its faculty of see, open the question about the cracking the symbol they represent: allowing the man to be aware of his position in the life. There isn 't image, there isn't face, that doesn't indícate the God's absence, that doesn't show the system's lie. The Bacon and Barceló's crucifixions detonate this lack, because a part of it; bring it to the present. The symbol opens to an unkown face from the other. The cross Is porority, meat. The painting, matter. The symbolic image recovers its powerful with those crucifixions.

Deciphering the language of nature: cryptography, secrecy, and alterity in Francis Bacon.

Science.gov (United States)

Clody, Michael C

2011-01-01

The essay argues that Francis Bacon's considerations of parables and cryptography reflect larger interpretative concerns of his natural philosophic project. Bacon describes nature as having a language distinct from those of God and man, and, in so doing, establishes a central problem of his natural philosophy—namely, how can the language of nature be accessed through scientific representation? Ultimately, Bacon's solution relies on a theory of differential and duplicitous signs that conceal within them the hidden voice of nature, which is best recognized in the natural forms of efficient causality. The "alphabet of nature"—those tables of natural occurrences—consequently plays a central role in his program, as it renders nature's language susceptible to a process and decryption that mirrors the model of the bilateral cipher. It is argued that while the writing of Bacon's natural philosophy strives for literality, its investigative process preserves a space for alterity within scientific representation, that is made accessible to those with the interpretative key.

Saldaña, Erick; Castillo, Luiz Saldarriaga; Sánchez, Jorge Cabrera; Siche, Raúl; de Almeida, Marcio Aurélio; Behrens, Jorge H; Selani, Miriam Mabel; Contreras-Castillo, Carmen J

2018-06-01

The aim of this study was to perform a descriptive analysis (DA) of bacons smoked with woods from reforestation and liquid smokes in order to investigate their sensory profile. Six samples of bacon were selected: three smoked bacons with different wood species (Eucalyptus citriodora, Acacia mearnsii, and Bambusa vulgaris), two artificially smoked bacon samples (liquid smoke) and one negative control (unsmoked bacon). Additionally, a commercial bacon sample was also evaluated. DA was developed successfully, presenting a good performance in terms of discrimination, consensus and repeatability. The study revealed that the smoking process modified the sensory profile by intensifying the "saltiness" and differentiating the unsmoked from the smoked samples. The results from the current research represent the first methodological development of descriptive analysis of bacon and may be used by food companies and other stakeholders to understand the changes in sensory characteristics of bacon due to traditional smoking process.

Crítica moral de Francis Bacon a la filosofía Francis Bacon's moral critique to philosophy

Full Text Available Este escrito muestra la crítica moral de Bacon a la filosofía, presente en sus obras de juventud, la cual es desarrollada en tres niveles: primero, los cargos a la filosofía por su inutilidad, segundo, las acusaciones a la falta de verdad y de método y, finalmente, la denuncia de falta de caridad y humildad. En conclusión, este estudio intentará sustentar que 1. La reforma baconiana no se restringe a un nuevo método ni a una nueva teoría de la materia; más allá de esto, encuentra un sustento en una nueva posición moral del hombre frente a la naturaleza, y 2. Que su proyecto epistemológico encuentra sentido en el trasfondo moral.This paper is about Bacon's moral critique to philosophy. This critique is present in his youth work and it is developed in three levels: first, charges against philosophy because of its uselessness; second, accusations against philosophy's lack of truth and method; and, finally, charges against philosophy's lack of charity and humility. Briefly, this study will state and support two hypotheses. 1. Bacon´s reform is not restricted to a new method neither a new theory of matter; beyond this; it is a new moral position about man in relation to nature. 2. His epistemological project makes sense in the moral background.

Mathematical subtleties and scientific knowledge: Francis Bacon and mathematics, at the crossing of two traditions.

Science.gov (United States)

Mori, Giuliano

2017-03-01

This article engages the much-debated role of mathematics in Bacon's philosophy and inductive method at large. The many references to mathematics in Bacon's works are considered in the context of the humanist reform of the curriculum studiorum and, in particular, through a comparison with the kinds of natural and intellectual subtlety as they are defined by many sixteenth-century authors, including Cardano, Scaliger and Montaigne. Additionally, this article gives a nuanced background to the 'subtlety' commonly thought to have been eschewed by Bacon and by Bacon's self-proclaimed followers in the Royal Society of London. The aim of this article is ultimately to demonstrate that Bacon did not reject the use of mathematics in natural philosophy altogether. Instead, he hoped that following the Great Instauration a kind of non-abstract mathematics could be founded: a kind of mathematics which was to serve natural philosophy by enabling men to grasp the intrinsic subtlety of nature. Rather than mathematizing nature, it was mathematics that needed to be 'naturalized'.

Consumer Perception of Retail Pork Bacon Attributes Using Adaptive Choice-based Conjoint Analysis and Maximum Differential Scaling.

Science.gov (United States)

McLean, K G; Hanson, D J; Jervis, S M; Drake, M A

2017-11-01

Bacon is one of the most recognizable consumer pork products and is differentiated by appearance, flavor, thickness, and several possible product claims. The objective of this study was to explore the attributes of retail bacon that influence consumers to purchase and consume bacon. An Adaptive Choice-Based Conjoint (ACBC) survey was designed for attributes of raw American-style bacon. An ACBC survey (N = 1410 consumers) and Kano questioning were applied to determine the key attributes that influenced consumer purchase. Attributes included package size, brand, thickness, label claims, flavor, price, and images of the bacon package displaying fat:lean ratio. Maximum Difference Scaling (MaxDiff) was used to rank appeal of 20 different bacon images with variable fat:lean ration and slice shape. The most important attribute for bacon purchase was price followed by fat:lean appearance and then flavor. Three consumer clusters were identified with distinct preferences. For 2 clusters, price was not the primary attribute. Understanding preferences of distinct consumer clusters will enable manufacturers to target consumers and make more appealing bacon. Adaptive Choice-Based Conjoint (ACBC) is a research technique that allows consumers to react to assembled products and identify product attributes that they prefer. Kano questions allow researchers to look at the individual aspects of a product and understand consumer sentiment and expectations towards those product qualities while Maximum Difference scaling allows consumers to directly rank single attributes of a product relative to one another. A combination of these 3 approaches can provide key understandings on consumer perception of retail bacon allowing companies to optimize and maximize their development and advertising resources. © 2017 Institute of Food Technologists®.

Ractopamine hydrochloride and immunological castration in pigs. Part 1: fresh belly characteristics for bacon processing and quality

Directory of Open Access Journals (Sweden)

Letícia Cristina COSTA E SILVA

Full Text Available Abstract The effects of ractopamine and immunological castration on belly characteristics, processing yield, physicochemical and sensory quality of bacon were investigated from two crossbred pigs under different conditions of animal production, diet, management and slaughter arranged in factorial design using 2 ractopamine levels (0 and 7.5 ppm and 3 genders (barrows, immunocastrated and gilts. Before processing, belly firmness, weight, length, width and thickness were measured, and then, bacon processing yield evaluated. After processing, bacon slices were digitally imaged and analyzed for lean meat and fat areas, pH, instrumental color of meat and fat, cooking loss and sensory quality. The ractopamine did not alter belly characteristics, but significantly increased the process yield and decreased cooking loss. Barrows and immunocastrated pigs showed firmer bellies, which could be advantageous for bacon processing and slicing. Barrows presented the highest total area of bacon slices. The results of this study indicate that both techniques ractopamine in the finishing diets and immunocastration of pigs can be combined with no further consequences for belly processing and to bacon quality and with some advantages.

Francis Bacon and the "Interpretation of Nature" in the late Renaissance.

Science.gov (United States)

Serjeantson, Richard

2014-12-01

The "interpretation of nature" (interpretatio naturae) is the leading idea in Francis Bacon's natural philosophy. But by contrast with his ideas about method, induction, or experiment, the significance of the "interpretation of nature" has received very little scholarly attention. This essay tests the originality of Bacon's idea by means of a focused survey of existing forms of Renaissance natural knowledge-Aristotelian and anti-Aristotelian natural philosophy, Galenic and Paracelsian medicine, natural magic, physiognomy, natural history-before turning to consider the much more prominent place of "interpretation" in the fields of Renaissance logic, revealed and natural theology, and law. It finds that Bacon's application of the idea of "interpretation" to nature was highly original, but also that certain important aspects of his conception have analogies in Renaissance civil law. The essay concludes by exploring the implications of these findings for a recent body of scholarship in the history of the sciences that invokes the notion of the "interpretation of nature" to characterize pre-Baconian natural philosophy more generally.

Long-term preservation of bacon by high energy electrons

International Nuclear Information System (INIS)

Hannah, K.W.; Simic, M.G.

1985-01-01

Extra long-term storage of frozen, vacuum packed, cured bacon can be achieved by electronation, using 3 MeV electrons generated by an electron accelerator. A combination process consisting of low nitrite curing (40 ppm), smoking, vacuum packaging in Saran plastic, electronation (1 to 3 Mrad), and freezing (-10 C) allows storage for at least 2 1/2 years without any noticeable loss in quality, e.g. color, appearance, smell, or taste. This process also eliminates microbiological hazards associated with Salmonella and C. botulinum. Six Mrad tons/hour throughput of a 3 MeV 50 kw electron beam accelerator for standard sliced bacon packaging indicates a practical and economic commercial use for this combination process. (author)

Sobre as afinidades entre a filosofia de Francis Bacon e o ceticismo

Full Text Available Este texto se ocupa de um exame, em caráter introdutório, das relações entre a reflexão de Bacon acerca das limitações de nossas faculdades e o ceticismo filosófico - um tema pouco considerado pela literatura mais recente, a despeito das muitas referências a tal filosofia. Ainda que, à primeira vista, tais referências possam parecer vagas e imprecisas, pensamos que um exame adequado de algumas delas pode revelar, não apenas a importância do tema para a compreensão de aspectos do seu próprio empreendimento, mas o interesse de Bacon pela literatura cética contemporânea. As peculiaridades de sua própria interpretação, por sua vez, parecem antecipar traços do modo como essa filosofia foi compreendida por filósofos posteriores, como Hume.This text focuses, in a preliminary way, on the relations between Francis Bacon's reflections on the limits of our cognitive faculties and philosophical skepticism, a theme not much considered by most of recent commentaries, in spite of Bacon's own explicit and numerous allusions to this philosophy. Even if these allusions seem at first sight somewhat loose and not very sharp, some of them reveal, we think, not only its relevance for understanding of some aspects of his own enterprise, but also Bacon's attention to the skeptical literature produced on the period. Moreover, the particularities of his own interpretation of skepticism seem to anticipate important features of the way this philosophy was understood by later philosophers as Hume.

Francis Bacon's behavioral psychology.

Science.gov (United States)

MacDonald, Paul S

2007-01-01

Francis Bacon offers two accounts of the nature and function of the human mind: one is a medical-physical account of the composition and operation of spirits specific to human beings, the other is a behavioral account of the character and activities of individual persons. The medical-physical account is a run-of-the-mill version of the late Renaissance model of elemental constituents and humoral temperaments. The other, less well-known, behavioral account represents an unusual position in early modern philosophy. This theory espouses a form of behavioral psychology according to which (a) supposed mental properties are "hidden forms" best described in dispositional terms, (b) the true character of an individual can be discovered in his observable behavior, and (c) an "informed" understanding of these properties permits the prediction and control of human behavior. Both of Bacon's theories of human nature fall under his general notion of systematic science: his medical-physical theory of vital spirits is theoretical natural philosophy and his behavioral theory of disposition and expression is operative natural philosophy. Because natural philosophy as a whole is "the inquiry of causes and the production of effects," knowledge of human nature falls under the same two-part definition. It is an inquisition of forms that pertains to the patterns of minute motions in the vital spirits and the production of effects that pertains both to the way these hidden motions produce behavioral effects and to the way in which a skillful agent is able to produce desired effects in other persons' behavior.

1974-04-01

Pork bellies were formulated to 0, 30, 60, 120, 170, or 340 mug of nitrite per g of meat and inoculated with Clostridium botulinum via pickle or after processing and slicing. Processed bacon was stored at 7 or 27 C and assayed for nitrite, nitrate, and botulinal toxin at different intervals. Nitrite levels declined during processing and storage. The rate of decrease was more rapid at 27 than at 7 C. Although not added to the system, nitrate was detected in samples during processing and storage at 7 and 27 C. The amount of nitrate found was related to formulated nitrite levels. No toxin was found in samples incubated at 7 C throughout the 84-day test period. At 27 C, via pickle, inoculated samples with low inoculum (210 C. botulinum per g before processing and 52 per g after processing) became toxic if formulated with 120 mug of nitrite per g of meat or less. Toxin was not detected in bacon formulated with 170 or 340 mug of nitrite per g of meat under these same conditions. Toxin was detected at all formulated nitrite levels in bacon inoculated via the pickle with 19,000 C. botulinum per g (4,300 per g after processing) and in samples inoculated after slicing. However, increased levels of formulated nitrite decreased the probability of botulinal toxin formation in bacon inoculated by both methods.

Francis Bacon: teory, method and contributions to the education

Roberto Carlos Simões Galvão

2007-04-01

Full Text Available In the present article, we propose a brief analysis of Francis Bacon’s thought (1561-1626 and his contributions to the Education. With Bacon, the old religious or metaphysical character of knowledge was substituted by the objectivity of the experimental science, something unknown until then. The science started to represent a means in search of an end, i.e., man’s control over nature. The desire of Bacon to promote a reorganization of the power of the human knowledge, not based on the old scholastic knowledge, but in the new scientific knowledge, was shared by educators, philosophers and statesmen of his time. The role of the school would be to assure the dissemination of this new knowledge which, properly unified, would be within reach of all the children

Epstein, Joel; Noel, Jeffrey; Finnegan, Megan; Watkins, Kate

2016-01-01

Researchers have developed many different computerized interventions designed to teach students about the dangers of substance use. Following in this tradition, we produced a series of video games called Bacon Brains . However, unlike many other programs, ours focused on the "Science of Addiction," providing lessons on how alcohol and other drugs affect the brain. The purpose of this study was to evaluate the effectiveness of our games in teaching students our science-based curriculum. We enrolled over 200 students and randomly assigned them to play our games or a different series of NIDA-produced games. Of the students in the Bacon Brains conditions, half were instructed to play collaboratively and the other half was told to play competitively. Results indicate significantly greater knowledge gains among students in Bacon Brains compared to the existing games (5.01 mean knowledge score difference; [F(1,242)=9.588, p=.002]). Girls demonstrated knowledge gains in both collaborative and competitive conditions, but boys demonstrated similar gains only in the competitive condition. Based on our outcomes, we conclude that video games can serve as an effective method of science instruction. We further discuss the importance of considering gender differences in light of differential response to collaborative vs. competitive learning environments.

Soladoye, O P; Shand, P; Dugan, M E R; Gariépy, C; Aalhus, J L; Estévez, M; Juárez, M

2017-09-01

This study aimed to examine the influence of cooking methods and pre-determined refrigerated storage days on the production of lipid oxidation (TBARS), protein oxidation (PROTOX) and heterocyclic aromatic amines (HAA) in bacon. Forty-four pork bellies selected from pigs varying in breed, sex and diets to introduce variability in composition were processed as bacon. Sliced-bacon was stored at 4°C either for 2 or 28days and these storage groups were cooked either with microwave or frying pan. Microwave led to significantly higher PROTOX (P0.05) by the cooking methods and storage times. Similarly, the fatty acid composition of pork belly did not significantly influence the production of HAA, TBARS and PROTOX produced in bacon during cooking. Overall, microwave cooking had lesser impact on the production of carcinogenic compounds in bacon with only minor impact on sensory attributes. Copyright © 2017. Published by Elsevier Ltd.

The Prehistory of Serendipity, from Bacon to Walpole.

Science.gov (United States)

Silver, Sean

2015-06-01

During the past four decades there has developed a burgeoning literature on the concept of serendipity, the name for sudden insights or conceptual breakthroughs that occur by chance or accident. Studies repeatedly note that it was Horace Walpole, the eighteenth-century man of letters, who coined the word. None of them, however, notice that Walpole's term is itself indebted to a much older tradition, invoking a formula developed by Francis Bacon. Recovering the prehistory of the term suggests that "serendipity," rather than being a name for a special mode of discovery invented by Walpole, has all along accompanied empiricism as the name for an essential gap in its epistemology. Serendipity bears directly on the "induction problem," or what has more recently been called the "conceptual leap." Though Walpole gave it its current name, versions of the concept have all along isolated a critical gap in the method of the sciences inaugurated by Bacon.

Effect of immunological castration management strategy on lipid oxidation and sensory characteristics of bacon stored under simulated food service conditions.

The objectives of this study were to determine the effect of 1) immunological castration (Improvest, a gonadotropin releasing factor analog-diphtheria toxoid conjugate) management strategy (age at slaughter and time of slaughter after second dose) and 2) sex on lipid oxidation and sensory characteristics of bacon stored under simulated food service conditions. For Objective 1, immunological castration management strategies included 24-wk-old immunologically castrated (IC) barrows 4, 6, 8, or 10 wk after the second Improvest dose (ASD); 26-wk-old IC barrows 6 wk ASD; and 28-wk-old IC barrows 8 wk ASD ( = 63). Objective 2 ( = 97) included IC barrows, physically castrated (PC) barrows, and gilts slaughtered at 24, 26, and 28 wks of age. Bellies from 2 slaughter dates were manufactured into bacon under commercial conditions. Bacon slices were laid out on parchment paper, packaged in oxygen-permeable poly-vinyl-lined boxes, and frozen (-33°C) for 1, 4, 8, or 12 wk to simulate food service conditions. At the end of each storage period, bacon was evaluated for lipid oxidation, moisture and lipid content, and sensory characteristics. Data from both objectives were analyzed using the MIXED procedure in SAS with belly as the experimental unit. For both objectives, as storage time increased, lipid oxidation of bacon increased ( 0.05). After 12 wk of frozen storage, lipid oxidation values for IC barrows, PC barrows, and gilts were still below 0.5 mg malondialdehyde/kg of meat, the threshold at which trained panelists may deem a food to be rancid. In conclusion, bacon shelf life characteristics were not altered by the immunological castration management strategy and bacon from IC barrows was similar to bacon from gilts. Therefore, bacon from IC barrows would result in shelf life and sensory quality similar to PC barrows and gilts.

Gemelli, Benedino

2003-01-01

The paper analyses Bacon's views of life, as contained in De Sapientia Veterum, Historia vitae et mortis, and in a newly published manuscript, entitled De vijs mortis. Bacon saw the prolongation of life as one of the main goals of science and medicine, According to him, life is the result of the action of spirits on matter. In order to preserve life, it is necessary to investigate various kinds of generation, notably, those which occurr without seeds. The study of putrefaction is also crucial for the prolongation of life.

A comparison of dioxins, dibenzofurans and coplanar PCBs in uncooked and broiled ground beef, catfish and bacon.

Schecter, A; Dellarco, M; Päpke, O; Olson, J

1998-01-01

The primary source of dioxins (PCDDs), dibenzofurans (PCDFs) and coplanar PCBs for the general population is food, especially meat, fish, and dairy products. However, most data on the levels of these chemicals is from food in the raw or uncooked state. We report here the effect of one type of cooking (broiling) on the levels of PCDDs, PCDFs, and coplanar PCBs in ground beef (hamburger), bacon and catfish. Samples of hamburger, bacon, and catfish were broiled and compared to uncooked samples in order to measure changes in the amounts of dioxins in cooked food. The total amount of PCDD, PCDF, and coplanar PCB TEQ decreased by approximately 50% on average for each portion as a result of broiling the hamburger, bacon and catfish specimens. The mean concentration (pg TEQ/kg, wet weight) of PCDDs, PCDFs, and coplanar PCBs, however, remained the same in the hamburger, increased by 83% in the bacon, and decreased by 34% in the catfish. On average, the total measured concentration (pg/kg) of the congeners of PCDDs, PCDFs, and coplanar PCBs increased 14% in the hamburger, increased 29% in the bacon, and decreased 33% in the catfish.

This paper establishes the 'emblematic' use of natural history as a propaedeutic to self-betterment in the Renaissance; in particular, in the natural histories of Gessner and Topsell, but also in the works of Erasmus and Rabelais. Subsequently, it investigates how Francis Bacon's conception of natural history is envisaged in relation to them. The paper contends that, where humanist natural historians understood the use of natural knowledge as a preliminary to individual improvement, Bacon conceived self-betterment foremost as a means to Christian charity, or social-betterment. It thus examines the transformation of the moralizing aspect of Renaissance natural history in Bacon's conception of his Great Instauration.

Toward an epistemology of nano-technosciences: Probing technoscience from a historical perspective: on today's surprising prevalence and relevance of Francis Bacon.

Science.gov (United States)

Schmidt, Jan C

2011-12-01

This paper aims to contribute to the attempts to clarify and classify the vague notion of "technosciences" from a historical perspective. A key question that is raised is as follows: Does Francis Bacon, one of the founding fathers of the modern age, provide a hitherto largely undiscovered programmatic position, which might facilitate a more profound understanding of technosciences? The paper argues that nearly everything we need today for an ontologically well-informed epistemology of technoscience can be found in the works of Bacon-this position will be called epistemological real-constructivism. Rather than realist or constructivist, empiricist or rationalist, Bacon's position can best be understood as real-constructivist since it challenges modern dichotomies. Reflection upon the contemporary relevance of Bacon could contribute to the expanding and critical discussion on technoscience. In the following I will reconstruct the term "technoscience". My finding is that at least four different understandings or types of the term "technoscience" co-exist. In a second step, I will analyze and elaborate on Bacon's epistemological position. I will identify central elements of the four different understandings in Bacon's work. Finally, I will conclude that the epistemology of technoscience is, indeed, very old-it is the epistemological position put forward by Bacon.

Effect of irradiation on stored vacuum packaged Wiltshire bacon

Wiltshire cured 'middle-cut' bacon (NaCl, 4.8%; 40 mg/kg NO 2 ; 53 mg/kg NO 3 ) was boned, sliced and vacuum packaged. It was irradiated (25 kGy: 10 kGy) and stored aerobically (5 0 : 15 0 ). At weekly intervals the bacon was evaluated bacteriologically and organoleptically (appearance, odour, colour of lean and fat) against unirradiated (control) samples). Results indicated that irradiation (10 kGy) did not permanently inhibit bacterial growth. After initial reductions in count of 0.99 g -1 (15 0 C) and log 3.61 g -1 (5 0 C), maximum numbers were reached in 28 days at 15 0 C (log 10.32 g -1 ) and in 35 days at 5 0 C (log 8.05 g -1 ). However viability was significantly affected by 25 kGy irradiation: final numbers reached being log 2.22 g -1 (15 0 C) at 35 days and log 3.38 g -1 (5 0 C) at 42 days. Appearance and colour (fat and lean) were not significantly impaired by irradiation. However the interaction of storage temperature (5 0 :15 0 C), irradiation (10 kGy: 25 kGy): duration of storage (42 days) and initial count (log 7.24 g -1 ) had pronounced adverse effects on odour judgements. Evaluation of odour changes in bacon due to irradiation require further investigation. This is especially so since it is often possible to detect odour changes in raw meat after doses as low as 0.5 kGy (Coleby 1959). (author)

Objectives were to characterize differences in pork bellies that were stored frozen for different durations prior to processing and characterize sensory properties of the bacon derived from those bellies when stored in either retail or food service style packaging. Bellies (n = 102) were collected from 4 different time periods, fresh bellies (never frozen) and bellies frozen for 2, 5, or 7 mo, and manufactured into bacon under commercial conditions. Food service bacon was packaged in oxygen-permeable polyvinyl lined boxes layered on wax-covered lined paper and blast frozen (-33 °C) for 45 or 90 d after slicing. Retail bacon was vacuum-packaged in retail packages and refrigerated (2 °C) in the dark for 60 or 120 d after slicing. At the end of respective storage times after slicing, bacon was analyzed for sensory attributes and lipid oxidation. Off-flavor and oxidized odor of bacon increased (P food service packaged bacon from frozen bellies, but was unchanged (P ≥ 0.07) with time in food service packaged bacon from fresh bellies. Lipid oxidation was also unchanged (P ≥ 0.21) over time in retail packaged bacon, with the exception of bellies frozen for 5 mo, which was increased from day 0 to day 90. Overall, off-flavor, oxidized odor, and lipid oxidation increased as storage time after processing increased. Freezing bellies before processing may exacerbate lipid oxidation as storage time after processing was extended. Bacon can be packaged and managed several different ways before it reaches the consumer. This research simulated food service (frozen) and retail packaged (refrigerated) bacon over a range of storage times after slicing. Off-flavor and oxidized odor increased as storage time after processing increased in both packaging types. Lipid oxidation increased as storage time after slicing increased to a greater extent in food service packaging. © 2014 Institute of Food Technologists®

Francis Bacon's natural history and civil history: a comparative survey.

Science.gov (United States)

Manzo, Silvia

2012-01-01

The aim of this paper is to offer a comparative survey of Bacon's theory and practice of natural history and of civil history, particularly centered on their relationship to natural philosophy and human philosophy. I will try to show that the obvious differences concerning their subject matter encompass a number of less obvious methodological and philosophical assumptions which reveal a significant practical and conceptual convergence of the two fields. Causes or axioms are prescribed as the theoretical end-products of natural history, whereas precepts are envisaged as the speculative outcomes derived from perfect civil history. In spite of this difference, causes and precepts are thought to enable effective action in order to change the state of nature and of man, respectively. For that reason a number of common patterns are to be found in Bacon's theory and practice of natural and civil history.

Comparison of three methods for determination of N-nitrosopyrrolidine in fried dry-cured bacon.

Gates, R A; Pensabene, J W; Fiddler, W

1984-01-01

The recently developed Eastern Regional Research Center ( ERRC ) dry column chromatographic procedure for determining N-nitrosopyrrolidine (NPYR) in fried cure-pumped bacon was evaluated for its applicability to fried dry-cured bacon. The method was then compared with 2 established procedures for volatile nitrosamine analysis in cured meat products: the multidetection thermal energy analyzer (MD) method and the mineral oil distillation (MOD) screening procedure. No significant difference (P less than 0.05) in NPYR values was found between the ERRC and MD procedures, but significant differences were found between the ERRC and MOD procedures and between the MOD and MD procedures. No artifactual nitrosamine formation was found in the ERRC procedure, but significant amounts were found in samples analyzed by the MOD procedure. The ERRC method was demonstrated to be rugged and very rapid. It is proposed that the ERRC method replace the MOD method as the official screening procedure for NPYR in fried bacon.

Little, K L; Bohrer, B M; Stein, H H; Boler, D D

2015-05-01

Objectives were to compare belly, bacon processing, bacon slice, and sensory characteristics from pigs fed high protein canola meal (CM-HP) or conventional canola meal (CM-CV). Soybean meal was replaced with 0 (control), 33, 66, or 100% of both types of canola meal. Left side bellies from 70 carcasses were randomly assigned to conventional or dry cure treatment and matching right side bellies were assigned the opposite treatment. Secondary objectives were to test the existence of bilateral symmetry on fresh belly characteristics and fatty acid profiles of right and left side bellies originating from the same carcass. Bellies from pigs fed CM-HP were slightly lighter and thinner than bellies from pigs fed CM-CV, yet bacon processing, bacon slice, and sensory characteristics were unaffected by dietary treatment and did not differ from the control. Furthermore, testing the existence of bilateral symmetry on fresh belly characteristics revealed that bellies originating from the right side of the carcasses were slightly (P≤0.05) wider, thicker, heavier and firmer than bellies from the left side of the carcass.

The Visual Shock of Francis Bacon: An essay in neuroesthetics

Semir eZeki

2013-12-01

Full Text Available In this paper we discuss the work of Francis Bacon in the context of his declared aim of giving a visual shock. We explore what this means in terms of brain activity and what insights into the brain’s visual perceptive system his work gives. We do so especially with reference to the representation of faces and bodies in the human visual brain. We discuss the evidence that shows that both these categories of stimuli have a very privileged status in visual perception, compared to the perception of other stimuli, including man-made artifacts such as houses, chairs and cars. We show that viewing face and house stimuli that depart significantly from a normal representation of faces and bodies entails a significant difference in the pattern of brain activation. We argue that Bacon succeeded in delivering his visual shock because he subverted the normal neural representation of faces and bodies, without at the same time subverting the representation of man-made artifacts.

The medical philosophy of Francis Bacon (1561-1626).

Science.gov (United States)

Boss, J

1978-01-01

Francis Bacon's view of man is dualistic but, although he takes note of mental faculties, he makes the relation between mind and body, rather than the substance of mind, the basis for enquiry into mental processes and, more particularly, for the medically relevant study of mind. (He uses "mind" and "soul" as equivalent terms.) The healing of the body requires study of the body, and the ineffectiveness of physicians is due to their failure in this respect rather than to the body's complexity. To learn about the body requires clinical observation and recording, together with the comparison of bodies, experiments on living animals and attention to pathological changes. The aims of medicine should include not only the restoration of health but also the relief of suffering and they are not to be limited by putting aside a disease as incurable. To learn from treatment it must be fixed in its ordering with controlled and limited variation. Bacon has no separation of medicine from natural science; his philosophy of medicine is his general philosophy of the advancement of knowledge, but limited to a particular field of application. If medicine is separated from natural philosophy it is changed wholly or greatly into empiricism.

Influence of partial replacement of NaCl with KCl on profiles of volatile compounds in dry-cured bacon during processing.

This study investigated the influence of partial substitution of NaCl with KCl on the formation of volatile compounds in bacons during processing using a purge and trap dynamic headspace GC/MS system. Three substitutions were 0% KCl (I), 40% KCl (II), and 70% KCl (III). The profiles of the volatile compounds significantly changed during processing, particularly during the drying/ripening. At the end of process, the bacons from substitution III formed significantly higher levels of lipid-derived volatiles, such as straight chain aldehydes, hydrocarbons than bacons from substitution I and II, whereas the latter formed higher levels of volatiles from amino acid degradation such as 3-methylbutanal. There were very few differences in volatile formation between 0% and 40% KCl application. These results suggest that K(+) substitution of Na(+) by more than 40% may significantly change profiles of volatiles in finished dry-cured bacons and therefore would result in changes in the product aroma and/or flavour.

The book classification of William Torrey Harris: influences of Bacon and Hegel in library classification

Directory of Open Access Journals (Sweden)

Rodrigo de Sales

2017-09-01

Full Text Available The studies of library classification generally interact with the historical contextualization approach and with the classification ideas typical of Philosophy. In the 19th century, the North-American philosopher and educator William Torrey Harris developed a book classification at the St. Louis Public School, based on Francis Bacon and Georg Wilhelm Friedrich Hegel. The objective of this essay is to analyze Harris’s classification, reflecting upon his theoretical and philosophical backgrounds. To achieve such objective, this essay adopts a critical-descriptive approach for analysis. Results show some influences of Bacon and Hegel in Harris’s classification.

They result from highly collinear variables and/or high-dimensional data. A special case of the latter occurs when the number of recorded variables exceeds the number of observations. The use of the BACON algorithm for outlier detection in multivariate data is extended here to include rank-deficient data. We present two approaches to identifying outliers in rank-deficient data based on the original BACON algorithm. The first algorithm projects the data onto a robust subspace of reduced dimension, while the second employs a ridge type regularization on the covariance matrix. Both algorithms are tested on real as well as simulated data sets with good results in terms of their effectiveness in outlier detection. They are also examined in terms of computational efficiency and found to be very fast, with particularly good scaling properties for increasing dimension.

Atmospheric pressure plasma (APP) is an emerging non-thermal pasteurization method for the enhancement of food safety. In this study, the effect of APP on the inactivation of pathogens inoculated onto bacon was observed. Sliced bacon was inoculated with Listeria monocytogenes (KCTC 3596), Escherichia coli (KCTC 1682), and Salmonella Typhimurium (KCTC 1925). The samples were treated with APP at 75, 100, and 125 W of input power for 60 and 90 s. Two gases, helium (10 lpm) or a mixture of helium and oxygen, (10 lpm and 10 sccm, respectively) were used for the plasma generation. Plasma with helium could only reduce the number of inoculated pathogens by about 1-2 Log cycles. On the other hand, the helium/oxygen gas mixture was able to achieve microbial reduction of about 2-3 Log cycles. The number of total aerobic bacteria showed 1.89 and 4.58 decimal reductions after plasma treatment with helium and the helium/oxygen mixture, respectively. Microscopic observation of the bacon after plasma treatment did not find any significant changes, except that the L∗-value of the bacon surface was increased. These results clearly indicate that APP treatment is effective for the inactivation of the three pathogens used in this study, although further investigation is needed for elucidating quality changes after treatment.

Full Text Available Como figure destacada en el complejo escenario político de la transición entre la dinastía Tudor y la dinastía Estuardo de Inglaterra, Francis Bacon (1561-1626 adoptó la teoría de los dos cuerpos del rey en sus textos políticos y jurídicos. Su uso de esta teoría tiene una estrecha conexión con conceptos centrales de su filosofía natural que testimonia la profunda conexión que Bacon encuentra entre la política y la naturaleza. En este trabajo, analizaré su utilización de la teoría medieval de los dos cuerpos del rey y la vinculación que esta tiene con el resto de la filosofía baconiana. Tomaré como eje para el análisis su discurso sobre la naturalización de los escoceses nacidos después de la subida al trono de James I, donde Bacon trata el concepto de los dos cuerpos del rey con más profundidad.As a prominent intellectual figure in the complex political arena of England, during the transition from Tudor to Stuart dinasties, Francis Bacon (1561-1626 assumes the medieval King's two bodies theory in his political and juridical writings. His use of this theory is extremely linked to central concepts of his natural philosphy, which testifies to the deep connection that Bacon finds between politics and nature. This paper addresses Bacon's use of the King's two bodies theory and its link to the rest of the Baconian philosophy. The focus of this study will be his discourse on the naturalization of Scots born after James I assumption of power, where Bacon deals more deeply with the King's two bodies theory.

1984-01-01

The results of this study are in agreement with the precepts established in studies published previously on beef, chicken, ham, and pork. The radiolysis compounds from bacon, chicken, ham, and pork are comparable in identity and amounts to those found in irradiated beef for comparable compositions and irradiation parameters (temperature, dose, etc.). The results of this study support the conclusions drawn in the CORC report of 'commonality in chemistry, predictability of products, and extrapolation of results.' Consequently, the same conclusions can be drawn concerning the wholesomeness of irradiated bacon, chicken, ham, and pork as for other irradiated meat products of similar composition and irradiation parameters as reported in the FASEB report and its supplements (I and II) on irradiated beef

Objectives were to evaluate effects of feeding soybean oil (SO) with varying levels of peroxidation on fresh belly characteristics, processing yields, and shelf life of commercially manufactured bacon stored under food-service style conditions. Fifty-six barrows were randomly assigned to 1 of 4 diets containing 10% fresh SO (22.5°C) or thermally processed SO (45°C for 288 h, 90°C for 72 h, or 180°C for 6 h), each infused with air at a rate of 15L/min. Individually housed pigs were provided ad libitum access to feed for 81 d. On d 82 pigs were slaughtered and on d 83 carcasses were fabricated and bellies collected for recording of weight, dimensions, and flop distance. Belly adipose tissue cores were collected for analysis of iodine value (IV) by near-infrared spectroscopy (NIR-IV). Bacon was manufactured at a commercial processing facility and sliced bacon was subsequently transferred to food-service style packaging and subjected to 0, 30, 60, or 90 d storage at -20°C. Stored bacon was evaluated for thiobarbituric acid reactive substances (TBARS) and trained sensory evaluation of oxidized odor and flavor. Fresh belly and bacon processing traits were analyzed as a one-way ANOVA with the fixed effect of SO; whereas, shelf life traits were analyzed as a one-way ANOVA repeated in time. There was no effect (P ≥ 0.30) of SO on belly weight, length, width, or thickness; but bellies of pigs fed 90°C SO had greater (P ≤ 0.04) flop distance (more firm) than all other SO treatments. Belly fat NIR-IV of pigs fed 90°C SO were 10.22 units less (P processed at 90°C and 180°C reduced belly adipose tissue IV, but feeding peroxidized SO did not affect processing yields or shelf life characteristics of commercially manufactured bacon.

Francis Bacon sob o olhar de Gilles Deleuze: a imagem como intensidade

Directory of Open Access Journals (Sweden)

Osvaldo Fontes Filho

2007-12-01

Full Text Available O ensaio de Gilles Deleuze La logique de la sensation é texto que se detém principalmente na prática e na eficácia da imagem. A pintura de Francis Bacon é ali tomada como paradigma de modernidade ao investir contra os clichês expressivos e ao produzir imagem junto à brutalidade dos fatos, como um contra-efeito do narrativo. Em uma obra que conjura todo modelo a representar, toda história a contar, “alguma coisa se passa”, explica Deleuze, “que define o funcionamento da pintura”. Algo se passa, tem lugar: o acontecimento de uma catástrofe e de uma histeria no ato de pintura que acomete a Figura de modo a transmitir uma potencial violência de reação e de expressão. O “Bacon” de Deleuze apresenta a realidade vivida em uma nova e não-convencional ordem de sensação. Neste artigo, são comentados os modos como o filósofo interpreta os atos físicos da pintura de Bacon — marcas aleatórias, varredura da massa pictural, escansão das superfícies —, procedimentos que introduzem no mundo visual da figuração a variedade caótica dos fatos e sentidos. Mostra-se como as faces e as figuras contorcidas, distorcidas, escorchadas de Bacon recebem uma voz conceitual complementar no texto de Deleuze. Consequentemente, focaliza-se a disposição de alguns conceitos do filósofo: diagrama, Figura, diferença, espaço háptico. Locados no espaço afetivo ou na “lógica da sensação” da pintura baconiana, esses conceitos atribuem legitimidade ao entrelaçamento e à co-implicação entre arte e filosofia. Uma última observação dá conta do fato de a prática da imagem em Bacon, apresentada por Deleuze no palco de uma modernidade particularmente solapada por um “dilúvio anestésico de imagens reprimindo a possibilidade de pensar”, evidenciar para o filósofo os rumos necessariamente sinuosos, “reptilíneos”, do pensamento moderno. Tanto o conceito como a forma criam por catástrofe, por conflagração, por varia

Looking at the way experiments and the heuristics of experimentation are embedded in Bacon's posthumous History of Dense and Rare and Descartes' Discourses 8, 9, 10 of the Meteorology, we will show that experiments help the investigator both in solving specific problems that could not have otherwise been foreseen and in generating relevant information that advances the scope of the investigation.

Civil history and poetry, certainty and truth in Francis Bacon

Directory of Open Access Journals (Sweden)

Silvia Manzo

2015-02-01

Full Text Available This article aims at studying key components of Francis Bacon’s theory of history and of his work as practitioner of civil history, particularly in regard to truth and certainty in historical narratives. It compares Bacon’s theories of history and poetry, and the way in which he conceives their relation to certainty, truth and fiction. It analyzes mainly two sorts of writings. On the one hand, it investigates the programmatic texts where Bacon’s views of history and poetry are developed. On the other hand, it examines the finished and unfinished civil histories written by Bacon as historian. In addition, the article evaluates Bacon’s stances against the background of Renaissance and early modern English historiography. It concludes that although history and poetry constitute separate branches in Bacon’s classification of learning, they share important elements, in keeping with the view of poetry maintained by his contemporary Philip Sidney. Thus, Bacon included fictional patterns in his historical narrative and distinguished certainties from conjectures in a particular way. This attitude towards civil history shows a strong contrast to Bacon’s methodology for natural histories, which, in order to reach certainty, staunchly recommends to exclude any fictional narrative in reporting the facts of nature.

Francis Bacon and Magnetical Cosmology.

Science.gov (United States)

Wang, Xiaona

2016-12-01

A short-lived but important movement in seventeenth-century English natural philosophy—which scholars call “magnetical philosophy” or “magnetical cosmology”—sought to understand gravity (both terrestrial and celestial) by analogy with magnetism. The movement was clearly inspired by William Gilbert’s De magnete (1600) and culminated with Robert Hooke’s prefiguring of the universal principle of gravitation, which he personally communicated to Isaac Newton in 1679. But the magnetical cosmology, as professed by those in the movement, differed from Gilbert’s philosophy in highly significant ways. Proponents never accepted Gilbert’s animistic account of magnets and seem tacitly to have accepted a belief in action at a distance that Gilbert himself rejected. This essay argues that Francis Bacon (1561–1626) had already provided just the adaptations to Gilbert’s philosophy that the later thinkers adopted, including an important endorsement of action at a distance, and that he should be recognized as playing an important role in the movement.

Francis Bacon: constructing natural histories of the invisible.

Science.gov (United States)

Rusu, Doina-Cristina

2012-01-01

The natural histories contained in Francis Bacon's Historia naturalis et experimentalis seem to differ from the model presented in De augmentis scientiarum and the Descriptio globi intellectualis in that they are focused on the defining properties of matter, its primary schematisms and the spirits. In this respect, they are highly speculative. In this paper I aim to describe the Historia naturalis et experimentalis as a text about matter theory, the histories of which are ascending from what is most evident to the senses to what is least accessible to them. Moreover, the Latin natural histories are parts of a methodological procedure in which the provisional rules and axioms obtained in one history can be used as theoretical assumptions for another history, thereby permitting one to delve ever more profoundly into the structure of nature.

From Bacon to Banks: the vision and the realities of pursuing science for the common good.

Science.gov (United States)

Sargent, Rose-Mary

2012-03-01

Francis Bacon's call for philosophers to investigate nature and "join in consultation for the common good" is one example of a powerful vision that helped to shape modern science. His ideal clearly linked the experimental method with the production of beneficial effects that could be used both as "pledges of truth" and for "the comforts of life." When Bacon's program was implemented in the following generation, however, the tensions inherent in his vision became all too real. The history of the Royal Society of London, from its founding in 1660 to the 42-year presidency of Joseph Banks (1778-1820), shows how these tensions led to changes in the way in which both the experimental method and the ideal of the common good were understood. A more nuanced understanding of the problems involved in recent philosophical analyses of science in the public interest can be achieved by appreciating the complexity revealed from this historical perspective.

Experimental Comparison of Efficiency of First Aid Dressings in Burning White Phosphorus on Bacon Model

Science.gov (United States)

Witkowski, Wojciech; Surowiecka-Pastewka, Agnieszka; Biesaga, Magdalena; Gierczak, Tomasz

2015-01-01

Background The aim of this study was to determine effectiveness of first aid dressings in extinguishing burning white phosphorous (WP), eliminating WP pieces from the surface, inhibiting re-ignition on the model (fresh bacon covered with military uniform), and preventing from late re-ignition caused by persistent WP pieces. Material/Methods Burning WP was extinguished with several dressings: tactical Military Dressing (WJ10), wet gauze, 2 hydrocolloids, and 3 prototypes of hydrocolloids developed by the authors. Results All examined dressings were effective in extinguishing WP provided that the entire area of the burning substance was completely covered. Moist gauze was especially effective in extinguishing WP, and also removed and absorbed the majority of the WP mass, preventing deeper penetration of WP particles. The immediate re-ignition was observed when all the remaining examined dressings were removed from the bacon. A stream of water was dangerous, as it splashed and transferred pieces of WP around. Conclusions Moist gauze placed on burning WP for approximately 3 min was most effective in extinguishing WP and removing most of the WP pieces. We recommend moist gauze, used once or twice, as the best primary means for WP elimination and preventing tissue penetration. As a dressing used for medical evacuation (MEDEVAC), or as a second step after complete removal of visible WP, innovative hydrocolloid or hydrogel dressings should be used. PMID:26264209

The Rule of Three for Prizes in Science and the Bold Triptychs of Francis Bacon.

Goldstein, Joseph L

2016-09-22

For many scientific awards, such as Nobels and Laskers, the maximum number of recipients is three. This Rule of Three forces selection committees to make difficult decisions that increase the likelihood of singling out those individuals who open a new field and continue to lead it. The Rule of Three is reminiscent of art's three-panel triptych, a form that the modern master Francis Bacon used to distill complex stories in a bold way. Copyright © 2016 Elsevier Inc.

La prolongation de la vie humaine selon Francis Bacon. Ou : quel Tithon voulons-nous être ?

Directory of Open Access Journals (Sweden)

Dominique Weber

2011-07-01

Full Text Available Afin de comprendre avec exactitude la manière dont Francis Bacon envisage la question de la prolongation de la vie humaine, il faut impérativement examiner l’assise théologique de la réflexion du philosophe à ce sujet. Il convient aussi de restituer l’intégration de cette réflexion dans les objectifs plus amples de la philosophie naturelle nouvelle. Enfin, il est nécessaire de comprendre les dimensions proprement morales de la question. Car la prolongation de la vie humaine n’est pas seulement, au sein de la philosophie naturelle nouvelle, un cas parmi d’autres des recherches qu’il faut désormais effectuer : en réalité, c’est elle qui lui donne et qui lui fixe son sens ; avec elle se joue l’effectivité de l’identité espérée entre science et puissance. Mais il faut encore préciser qu’il ne s’agit aucunement pour l’homme de vieillir pour vieillir : il s’agit pour lui de pouvoir vieillir bien. Les leçons que Bacon tire de la fable de Tithon sont ici véritablement décisives.

Liu, Xiaofang; Zhou, Shu; Zhu, Quanfei; Ye, Yong; Chen, Huaixia

2014-09-01

A sample pretreatment method, solid-phase extraction combined with dispersive liquid-liquid microextraction (SPE-DLLME), was established for the sensitive determination of polycyclic aromatic hydrocarbons (PAHs) in smoked bacon samples. In the SPE-DLLME process, three PAHs including naphthalene (Naph), phenanthrene (Phen) and pyrene (Pyr) were extracted from samples and transferred into C18 SPE cartridge. The target analytes were subsequently eluted with 1.2 ml of acetonitrile-dichloromethane (5:1, v/v) mixture solution. The eluent was injected directly into the 5.0 ml ultrapure water in the subsequent DLLME procedure. The sedimented phase was concentrated under a gentle nitrogen flow to 120.0 µl. Finally, the analytes in the extraction solvent were determined by high-performance liquid chromatography with a ultra-violet detector. Some important extraction parameters affecting the performance, such as the sample solution flow rate, breakthrough volume, salt addition as well as the type and volume of the elution solvent were optimized. The developed method provided an ultra enrichment factors for PAHs ranged from 3478 to 3824. The method was applied for the selective extraction and sensitive determination of PAHs in smoked bacon samples. The limits of detection (S/N = 3) were 0.05, 0.01, 0.02 μg kg(-1) for Naph, Phen, Pyr, respectively. © The Author [2013]. Published by Oxford University Press. All rights reserved.

Experimental implementation of the Bacon-Shor code with 10 entangled photons

Science.gov (United States)

Gimeno-Segovia, Mercedes; Sanders, Barry C.

The number of qubits that can be effectively controlled in quantum experiments is growing, reaching a regime where small quantum error-correcting codes can be tested. The Bacon-Shor code is a simple quantum code that protects against the effect of an arbitrary single-qubit error. In this work, we propose an experimental implementation of said code in a post-selected linear optical setup, similar to the recently reported 10-photon GHZ generation experiment. In the procedure we propose, an arbitrary state is encoded into the protected Shor code subspace, and after undergoing a controlled single-qubit error, is successfully decoded.

[Effect of fried bacon and parsley sauce on gastrointestinal symptoms in healthy old boys footballer].

Grønbæk, Henning; Jensen, Mogens Pfeiffer

2012-12-03

Knowledge of the importance of diet on gastrointestinal function and symptoms is generally poorly. In recent years, The New Nordic Food Culture is suggested to have favourable effects. Unfortunally there are huge waiting lists at the most popular restaurants, so we investigated the more traditional "Nordic kitchen". There are no previous studies concerning intake of fried bacon and parsley sauce (FBPS) in healthy middle-aged footballers. Non-blinded, non-randomized, crossover study with a questionnaire survey of 18 healthy old boys footballers before and after FBPS intake. Ten players responded to the questionnaire, including one who was not exposed to FBPS. The median intake was 15 pieces of fried bacon (range 12-23), 1.5 dl parsley sauce (range 1-5 dl), and eight potatoes (range 6-30), but no dessert. We found a significantly increased stool frequency and a trend towards change in consistency compared to baseline. We found increased abdominal pain and a decrease in general well-being, but could not demonstrate any impact on complaints from the family. In otherwise healthy old boys footballers the FBPS diet has great impact on a range of gastrointestinal symptoms. FBPS affected stool frequency and abdominal pain, but caused no effect on family complaints. We cannot exclude a dose-response effect or a gender/age phenomenon; and we suggest supplemental dose-response studies and studies including women of all ages. Further, we recommend a detailed dietary assessment before referring patients with gastrointestinal symptoms for invasive procedures like colonoscopy or CT-scanning. none none.

Philosophy of experiment in early modern England: the case of Bacon, Boyle and Hooke.

Science.gov (United States)

Anstey, Peter R

2014-01-01

Serious philosophical reflection on the nature of experiment began in earnest in the seventeenth century. This paper expounds the most influential philosophy of experiment in seventeenth-century England, the Bacon-Boyle-Hooke view of experiment. It is argued that this can only be understood in the context of the new experimental philosophy practised according to the Baconian theory of natural history. The distinctive typology of experiments of this view is discussed, as well as its account of the relation between experiment and theory. This leads into an assessment of other recent discussions of early modern experiment, namely, those of David Gooding, Thomas Kuhn, J.E. Tiles and Peter Dear.

Images of trauma: pain, recognition, and disavowal in the works of Frida Kahlo and Francis Bacon.

Science.gov (United States)

Bose, Joerg

2005-01-01

The role of art in the encounter with trauma and destructiveness is comparatively studied in the works of Frida Kahlo and Francis Bacon as examples of a direct and a more indirect way of dealing with such experiences. A creative product may function intrapsychically as a kind of messenger between dissociated self-states and consciousness, and it may also serve as a witnessing presence in a self-supporting and self-constituting way. Artistic work may thus be used by the artist for an expressive as well as for a protective purpose, as a means of sympathetic participation in painful experience, or as a medium for a view from the outside. The act itself of finding and of making expressive forms at the time of traumatic experience is a remarkable assertion of the human capability to synthesize and to counteract fragmenting dissociative processes.

Four centuries on from Bacon: progress in building health research systems to improve health systems?

Science.gov (United States)

Hanney, Stephen R; González-Block, Miguel A

2014-09-23

In 1627, Francis Bacon's New Atlantis described a utopian society in which an embryonic research system contributed to meeting the needs of the society. In this editorial, we use some of the aspirations described in New Atlantis to provide a context within which to consider recent progress in building health research systems to improve health systems and population health. In particular, we reflect on efforts to build research capacity, link research to policy, identify the wider impacts made by the science, and generally build fully functioning research systems to address the needs identified. In 2014, Health Research Policy and Systems has continued to publish one-off papers and article collections covering a range of these issues in both high income countries and low- and middle-income countries. Analysis of these contributions, in the context of some earlier ones, is brought together to identify achievements, challenges and possible ways forward. We show how 2014 is likely to be a pivotal year in the development of ways to assess the impact of health research on policies, practice, health systems, population health, and economic benefits.We demonstrate how the increasing focus on health research systems will contribute to realising the hopes expressed in the World Health Report, 2013, namely that all nations would take a systematic approach to evaluating the outputs and applications resulting from their research investment.

Nesse registro, consideramos alguns aspectos das narrativas de Hesíodo sobre o mito de Prometeu, bem como algumas observações de filósofos modernos como Francis Bacon e Thomas Hobbes sobre como essa fábula narra a interpretação de uma condição humana fundada em uma competição análoga à uma interminável luta de titãs. Condição humana essa oriunda da desobediência às vontades dos deuses do Olimpo, cristalizada na expressão de uma cultura da competição que visa não apenas agradar a esses deuses, detentores do poder no Olimpo, mas também igualar certos homens a eles.

The Construction of Epistolary Identity in a Gentry’s Communication Network of the Seventeenth Century: The Case of Jane Lady Cornwallis Bacon

Directory of Open Access Journals (Sweden)

Gabriella Del Lungo Camiciotti

2014-04-01

Full Text Available There has recently been increasing scholarly interest in early modern correspondence and specifically also in women’s letter writing and reading. Starting from the late Middle Ages familiar responsibilities and domestic obligations led many women to write to their absent husbands or other relatives to exchange health news and inform them about family affairs. It is however in the early modern period that corresponding with relatives and friends became a widespread social practice ranging from official to familiar and personal correspondence; in this period female literacy increased thus allowing growing numbers of women to write and read their own letters. A growing number of female voices can thus be heard depicting early modern social life. The article focuses on a neglected aspect of women’s correspondence: it investigates not the sender’s epistolary identity, but that of the recipient through the analysis of the personal correspondence of Lady Cornwallis Bacon. The main theme of the article is to show how the epistolary identity of an early modern gentlewoman was constructed by her correspondents. It is assumed that modes of communicating information and achieving a specific goal through letters varied not only according to the relationship connecting the correspondents but also the purpose and content of letters.

Eighty-four crossbred gilts were used to evaluate the effects of dietary choice white grease (CWG) or poultry fat (PF) on growth performance, carcass characteristics, and quality characteristics of longissimus muscle (LM), belly, and bacon of growing-finishing pigs. Pigs (initially 60 kg) were fed a control diet with no added fat or diets containing 2, 4, or 6% CWG or PF. Diets were fed from 60 to 110 kg and contained 2.26 g lysine/Mcal ME. Data were analyzed as a 2 x 3 factorial plus a control with main effects of fat source (CWG and PF) and fat level (2, 4, and 6%). Pigs fed the control diet, 2% fat, and 4% fat had greater (P 0.05) were observed for ADG, dressing percentage, leaf fat weight, LM pH, backfat depth, LM area, percentage lean, LM visual evaluation, LM waterholding capacity, Warner-Bratzler shear and sensory evaluation of the LM and bacon, fat color and firmness measurements, or bacon processing characteristics. Adding dietary fat improved G/F and altered the fatty acid profiles of the LM and bacon, but differences in growth rate, carcass characteristics, and quality and sensory characteristics of the LM and bacon were minimal. Dietary additions of up to 6% CWG or PF can be made with little effect on quality of pork LM, belly, or bacon.

Full Text Available The mature poetry of Tadeusz Różewicz seems to be at odds with both modernist and postmodern literary tenets. It undeniably makes abundant use of intertextuality (including self-quotations, but in spite of this [post]modernist tendency it does resist self-referential impersonality. Różewicz again immerses allusions to images, texts and other artifacts – which, according to formalist and structuralist interpretations, should disengage themselves from an artist’s biography in order to achieve aesthetic autonomy – in the current of life, devoid of an innate sense and always identical to itself. In fact, life cannot be apprehended by art, and precisely, Różewicz tries to thematize this impossibility by producing texts or rather poetical acts that could be classified as self-effacing artifacts. He even succeeded in discrediting the modernist epiphany (which has a double status, i.e. as a poetical device and a window on the transcendent by replacing it with loquacious anticlimaxes. The fragmentary, disintegrating form of his later poetry (the long poem “Francis Bacon or Diego Velázquez in a dentist’s chair” is a perfect – or rather consciously imperfect – implementation of this form does not pretend to be a representation of a human being’s disintegrating existence.

Over a long period of time, particularly from the nineteenth century on, Francis Bacon's philosophy has been interpreted as centred on the Novum organum and focused on the role that a well-organized method may play in securing a reliable knowledge of nature. In fact, if we examine Bacon's oeuvre as a whole, including some recent manuscript findings (De vijs mortis), we can safely argue that the issues addressed in the Novum organum represent only a part of Bacon's agenda, and not even the most important ones. By contrast, it is apparent that, from the very beginning of his investigations, he emphasized the central role of medicine, the need to establish new approaches in the study of the vital functions and the importance of promoting new discoveries in the medical field, not so much to find a cure for the many illnesses that plagued mankind as to prolong human life. In this sense, Historia vitae et mortis plays a central role in Bacon's programme to extend human knowledge and power, for, in his opinion, human beings could recover their lost ability to live a long and healthy life by embarking on careful investigations of nature. Far from being a purely descriptive or abstract exercise, Bacon's historia can therefore be seen as an operative tool to attain some of mankind's basic aims.

Themes of mastery, domination and power are familiar to any scholar of modern technology. Science is commonly cast as enabling the technological control over both the natural and physical worlds. Indeed, Francis Bacon famously equated scientific knowledge with power itself—stating that ‘knowledge itself is a power’ (Bacon in Montagu 1825, 71). Bacon’s now ubiquitous phrase—commonly repeated as the banal ‘knowledge is power’—was an attempt to combat three heresies in scriptural interpretation ...

Exploratory experiments and experientia literata: (re thinking experimentation

Directory of Open Access Journals (Sweden)

Anabel Cardoso Raicik

2018-04-01

Full Text Available Francis Bacon is sometimes referred to as the first experimental philosopher, and his philosophy is usually tied to the common empirical-inductive idea. In order to show a new Baconian image, this article analyzes parts of his main work, the Novum Organum, and presents his concept of experientia literata, little known. In addition, it explicit counterpoints between some considerations presented by Bacon, particularly about the literata experientia, and certain conceptions of the "new experimentalism", especially in light of the concept of exploratory experimentation outlined by Steinle. Finally, it approaches some implications of these reflections for science teaching.

Makoil, Inc., of Orange, California, with the support of the U.S. Department of Energy has reprocessed and reinterpreted the 3D seismic survey of the Grant Canyon area, Railroad Valley, Nye County, Nevada. The project was supported by Dept. of Energy Grant DE-FG26-00BC15257. The Grant Canyon survey covers an area of 11 square miles, and includes Grant Canyon and Bacon Flat oil fields. These fields have produced over 20 million barrels of oil since 1981, from debris slides of Devonian rocks that are beneath 3,500 to 5,000 ft of Tertiary syntectonic deposits that fill the basin of Railroad Valley. High-angle and low-angle normal faults complicate the trap geometry of the fields, and there is great variability in the acoustic characteristics of the overlying valley fill. These factors combine to create an area that is challenging to interpret from seismic reflection data. A 3D seismic survey acquired in 1992-93 by the operator of the fields has been used to identify development and wildcat locations with mixed success. Makoil believed that improved techniques of processing seismic data and additional well control could enhance the interpretation enough to improve the chances of success in the survey area. The project involved the acquisition of hardware and software for survey interpretation, survey reprocessing, and reinterpretation of the survey. SeisX, published by Paradigm Geophysical Ltd., was chosen as the interpretation software, and it was installed on a Dell Precision 610 computer work station with the Windows NT operating system. The hardware and software were selected based on cost, possible addition of compatible modeling software in the future, and the experience of consulting geophysicists in the Billings area. Installation of the software and integration of the hardware into the local office network was difficult at times but was accomplished with some technical support from Paradigm and Hewlett Packard, manufacturer of some of the network equipment.

Effects of Feeding Purple Rice (Oryza sativa L. Var. Glutinosa) on the Quality of Pork and Pork Products

Science.gov (United States)

Jaturasitha, Sanchai; Ratanapradit, Punnares; Piawong, Witapong; Kreuzer, Michael

2016-01-01

Purple rice is a strain of glutaneous rice rich in anthocyanins and γ-oryzanol. Both types of compounds are involved in antioxidant and lipid metabolism of mammals. Three experimental diet types were used which consisted approximately by half either of purple rice, white rice or corn. Diets were fed to 3×10 pigs growing from about 30 to 100 kg. Meat samples were investigated either as raw or cured loin chops or as smoked bacon produced from the belly. Various physicochemical traits were assessed and data were evaluated by analysis of variance. Traits describing water-holding capacity (drip, thaw, and cooking losses) and tenderness (sensory grading, shear force) of the meat were mostly not significantly affected by the diet type. However, purple rice feeding of pigs resulted in lower fat and cholesterol contents of loin and smoked bacon compared to white rice, but not compared to corn feeding except of the fat content of the loin. The shelf life of the raw loin chops was improved by purple rice as well. In detail, the occurrence of thiobarbituric acid reactive substances after 9 days of chilled storage was three to four times higher in the white rice and corn diets than with purple rice. The n-6:n-3 ratio in the raw loin chops was 9:1 with purple rice and clearly higher with 12:1 with the other diets, meat lipids. Level and kind of effect of purple rice found in raw meat was not always recovered in the cured loin chops and the smoked bacon. Still the impression of flavor and color, as well as overall acceptability were best in the smoked bacon from the purple-rice fed pigs, whereas this effect did not occur in the cured loin chops. These findings suggest that purple rice has a certain, useful, bioactivity in pigs concerning meat quality, but some of these effects are of low practical relevance. Further studies have to show ways how transiency and low recovery in meat products of some of the effects can be counteracted. PMID:26949957

Geologic field trip guide to Mount Mazama and Crater Lake Caldera, Oregon

Science.gov (United States)

Bacon, Charles R.; Wright, Heather M.

2017-08-08

Crater Lake partly fills one of the most spectacular calderas of the world—an 8 by 10 kilometer (km) basin more than 1 km deep formed by collapse of the Mount Mazama volcano during a rapid series of explosive eruptions ~7,700 years ago. Having a maximum depth of 594 meters (m), Crater Lake is the deepest lake in the United States. Crater Lake National Park, dedicated in 1902, encompasses 645 square kilometers (km2) of pristine forested and alpine terrain, including the lake itself, and virtually all of Mount Mazama. The geology of the area was first described in detail by Diller and Patton (1902) and later by Williams (1942), whose vivid account led to international recognition of Crater Lake as the classic collapse caldera. Because of excellent preservation and access, Mount Mazama, Crater Lake caldera, and the deposits formed by the climactic eruption constitute a natural laboratory for study of volcanic and magmatic processes. For example, the climactic ejecta are renowned among volcanologists as evidence for systematic compositional zonation within a subterranean magma chamber. Mount Mazama’s climactic eruption also is important as the source of the widespread Mazama ash, a useful Holocene stratigraphic marker throughout the Pacific Northwest United States, adjacent Canada, and offshore. A detailed bathymetric survey of the floor of Crater Lake in 2000 (Bacon and others, 2002) provides a unique record of postcaldera eruptions, the interplay between volcanism and filling of the lake, and sediment transport within this closed basin. Knowledge of the geology and eruptive history of the Mount Mazama edifice, enhanced by the caldera wall exposures, gives exceptional insight into how large volcanoes of magmatic arcs grow and evolve. In addition, many smaller volcanoes of the High Cascades beyond the limits of Mount Mazama provide information on the flux of mantle-derived magma through the region. General principles of magmatic and eruptive processes revealed by

Construction of scientific knowledge in motor learning: history and perspectives

Full Text Available The present work aims to inquire the construction of scientific knowledge in the motor learning area. A necessary historical retrospective on this study field considers the epistemology of Francis Bacon, Karl Popper, Paul Feyerabend and Thomas Kuhn. Bacon and Popper’s conceptions show to be inadequate to explain the scientific progress of motor learning. Feyerabend’s ideas are also inadequate as they lack coherency, even though in some aspects they are adequate. The Kuhnian approach, however, seems more satisfactory, particularly with regard to the notion of “crisis of paradigm” between the ecological approach and the information-processing approach. A critique is offered from human and social sciences perspective. This leads us to reflect on the possible growth of a new paradigm and consider scientific practice as a social practice.

A collection of more than 70 synthetic organic pigments were analysed using pyrolysis-gas chromatography-mass spectrometry (Py-GC-MS). We report on the analysis of diketo-pyrrolo-pyrrole, isoindolinone and perylene pigments which are classes not previously reported as being analysed by this technique. We also report on a number of azo pigments (2-naphthol, naphthol AS, arylide, diarylide, benzimidazolone and disazo condensation pigments) and phthalocyanine pigments, the Py-GC-MS analysis of which has not been previously reported. The members of each class were found to fragment in a consistent way and the pyrolysis products are reported. The technique was successfully applied to the analysis of paints used by the artist Francis Bacon (1909-1992), to simultaneously identify synthetic organic pigments and synthetic binding media in two samples of paint taken from Bacon's studio and micro-samples taken from three of his paintings and one painting attributed to him.

DESEJO DE LUZ: O CRISTIANISMO E O SURGIMENTO DA FILOSOFIA MODERNA EM LUDWIG FEUERBACH / A DESIRE FOR LIGHT: CHRISTIANITY AND THE EMERGENCE OF MODERN PHILOSOPHY IN LUDWIG FEUERBACH

Directory of Open Access Journals (Sweden)

Chrysantho Figueiredo

2015-04-01

Full Text Available This is a review of Ludwig Feuerbach’s book introduction Geshichte der Neuern Philosophie von Bacon bis Spinoza. The original text is in German, the review is in Portuguese. However, we present here, attached, the translated text, also unpublished and original. In 1841's The Essence of Christianity, Feuerbach presents in a most complete way his own version of the radical humanism which excited the young hegelians of his generation. However, it is between 1833 and 1838 that Feuerbach formulates his own philosophical point of view from the critique of the major philosophical systems of modernity. The History of Philosophy from Bacon to Spinoza, published in 1833, is the first of his historicalphilosophical works which, apart from the critique of the philosophers indicated by the title, presents also a singular feuerbachian vision of history as a whole, showing how modern philosophy emerges from the inherent contradictions of the Christian religious spirit.

Historic, Recent, and Future Subsidence, Sacramento-San Joaquin Delta, California, USA

Directory of Open Access Journals (Sweden)

Steven J Deverel

2010-08-01

Full Text Available To estimate and understand recent subsidence, we collected elevation and soils data on Bacon and Sherman islands in 2006 at locations of previous elevation measurements. Measured subsidence rates on Sherman Island from 1988 to 2006 averaged 1.23 cm/year (0.5 in/yr and ranged from 0.7 to 1.7 cm/year (0.3 to 0.7 in/year. Subsidence rates on Bacon Island from 1978 to 2006 averaged 2.2 cm/year (0.9 in/yr and ranged from 1.5 to 3.7 cm/year (0.6 to 1.5 in/yr. Changing land-management practices and decreasing soil organic matter content have resulted in decreasing subsidence rates. On Sherman Island, rates from 1988 to 2006 were about 35% of 1910 to 1988 rates. For Bacon Island, rates from 1978 to 2006 were about 40% less than the 1926-1958 rates. To help understand causes and estimate future subsidence, we developed a subsidence model, SUBCALC, that simulates oxidation and carbon losses, consolidation, wind erosion, and burning and changing soil organic matter content. SUBCALC results agreed well with measured land-surface elevation changes. We predicted elevation decreases from 2007 to 2050 will range from a few centimeters to over 1.3 m (4.3 ft. The largest elevation declines will occur in the central Sacramento-San Joaquin Delta. From 2007 to 2050, the most probable estimated increase in volume below sea level is 349,956,000 million cubic meters (281,300 acre-feet. Consequences of this continuing subsidence include increased drainage loads of water quality constituents of concern, seepage onto islands, and decreased arability.

Microbiological hazard analysis of ready-to-eat meats processed at a food plant in Trinidad, West Indies

Directory of Open Access Journals (Sweden)

Stacey-Marie Syne

2013-07-01

Full Text Available Background: A bacteriological assessment of the environment and food products at different stages of processing was conducted during the manufacture of ready-to-eat (RTE chicken franks, chicken bologna and bacon at a large meat processing plant in Trinidad, West Indies. Methods: Samples of air, surfaces (swabs, raw materials, and in-process and finished food products were collected during two separate visits for each product type and subjected to qualitative or quantitative analysis for bacterial zoonotic pathogens and fecal indicator organisms. Results: Staphylococcus aureus was the most common pathogen detected in pre-cooked products (mean counts = 0.66, 1.98, and 1.95 log10CFU/g for franks, bologna, and bacon, respectively. This pathogen was also found in unacceptable levels in 4 (16.7% of 24 post-cooked samples. Fifty percent (10 of 20 of pre-cooked mixtures of bacon and bologna were contaminated with Listeria spp., including four with L. monocytogenes. Pre-cooked mixtures of franks and bologna also contained E. coli (35 and 0.72 log10 CFU/g, respectively while 5 (12.5% of 40 pre-cooked mixtures of chicken franks had Salmonella spp. Aerobic bacteria exceeded acceptable international standards in 46 (82.1% of 56 pre-cooked and 6 (16.7% of 36 post-cooked samples. Both pre-and post-cooking air and surfaces had relatively high levels of aerobic bacteria, Staphylococcus aureus and coliforms, including equipment and gloves of employees. A drastic decrease in aerobic counts and Staphylococcus aureus levels following heat treatment and subsequent increase in counts of these bacteria are suggestive of post-cooking contamination. Conclusion: A relatively high level of risk exists for microbial contamination of RTE meats at the food plant investigated and there is a need for enhancing the quality assurance programs to ensure the safety of consumers of products manufactured at this plant.

Hippocrates' complaint and the scientific ethos in early modern England.

Science.gov (United States)

Yeo, Richard

2018-04-01

Among the elements of the modern scientific ethos, as identified by R.K. Merton and others, is the commitment of individual effort to a long-term inquiry that may not bring substantial results in a lifetime. The challenge this presents was encapsulated in the aphorism of the ancient Greek physician, Hippocrates of Kos: vita brevis, ars longa (life is short, art is long). This article explores how this complaint was answered in the early modern period by Francis Bacon's call for the inauguration of the sciences over several generations, thereby imagining a succession of lives added together over time. However, Bacon also explored another response to Hippocrates: the devotion of a 'whole life', whether brief or long, to science. The endorsement of long-term inquiry in combination with intensive lifetime involvement was embraced by some leading Fellows of the Royal Society, such as Robert Boyle and Robert Hooke. The problem for individuals, however, was to find satisfaction in science despite concerns, in some fields, that current observations and experiments would not yield material able to be extended by future investigations.

We reapply our approach to designing nanophotonic quantum memories in order to formulate an optical network that autonomously protects a single logical qubit against arbitrary single-qubit errors. Emulating the nine-qubit Bacon-Shor subsystem code, the network replaces the traditionally discrete syndrome measurement and correction steps by continuous, time-independent optical interactions and coherent feedback of unitarily processed optical fields.

Full Text Available The objective of this study was to assess the potential utilization of ostrich meat trimming in hamburger preparation, as well as its physicochemical and sensory characterization. Using ostrich meat trimmings from the legs and neck, four different formulations were prepared with varied amounts of bacon and textured soybean protein. Physical analysis of yield, shrinkage percentage, and water retention capacity and chemical analysis of proximate composition, cholesterol levels, and calories were performed. The formulations underwent sensory analysis by 52 potential ostrich meat consumers, who evaluated tenderness, juiciness, flavor, and purchase intent. The formulations containing textured soybean protein showed the highest yield, lowest shrinkage percentage, and highest water retention capacity. Lipid content varied from 0.58 to 4.99%; protein from 17.08 to 21.37%; ash from 3.00 to 3.62%; moisture from 73.87 to 76.27%; cholesterol from 22.54 to 32.11 mg.100 g-1; and calorie from 87.22 to 163.42 kcal.100 g-1. All formulations showed low cholesterol and calorie levels, even that containing 10% bacon and 3.5% textured soybean protein, which achieved the best scores and acceptance by the panelists.

Nitrosamines in bacon: a case study of balancing risks.

OpenAIRE

McCutcheon, J W

1984-01-01

Nitrite has been used for centuries to preserve, color, and flavor meat. Today, about 10 billion pounds of cured meat products are produced annually, accounting for some one-tenth of the American food supply. Regulators became concerned about the safety of using nitrite in the early 1960s when studies showed the presence of carcinogenic nitrosamines in cured meat products. In the early 1970s, a study at the Massachusetts Institute of Technology implicated nitrite itself as a carcinogen. As st...

234U/238U and δ87Sr in peat as tracers of paleosalinity in the Sacramento-San Joaquin Delta of California, USA

Drexler, J.Z.; Paces, J.B.; Alpers, C.N.; Windham-Myers, L.; Neymark, L.A.; Bullen, T.D.; Taylor, H.E.

2014-01-01

Highlights: • Concentrations and isotopic values of Sr and U in peat were used to trace paleosalinity. • A three-end-member mixing model was constructed using values from water sources. • Paleosalinity of peat samples was determined relative to that of end members. • δ 87 Sr values were altered during and after the California Gold Rush period. • Oligohaline and freshwater marshes have long existed in the Sacramento-San Joaquin Delta. - Abstract: The purpose of this study was to determine the history of paleosalinity over the past 6000+ years in the Sacramento-San Joaquin Delta (the Delta), which is the innermost part of the San Francisco Estuary. We used a combination of Sr and U concentrations, δ 87 Sr values, and 234 U/ 238 U activity ratios (AR) in peat as proxies for tracking paleosalinity. Peat cores were collected in marshes on Browns Island, Franks Wetland, and Bacon Channel Island in the Delta. Cores were dated using 137 Cs, the onset of Pb and Hg contamination from hydraulic gold mining, and 14 C. A proof of concept study showed that the dominant emergent macrophyte and major component of peat in the Delta, Schoenoplectus spp., incorporates Sr and U and that the isotopic composition of these elements tracks the ambient water salinity across the Estuary. Concentrations and isotopic compositions of Sr and U in the three main water sources contributing to the Delta (seawater, Sacramento River water, and San Joaquin River water) were used to construct a three-end-member mixing model. Delta paleosalinity was determined by examining variations in the distribution of peat samples through time within the area delineated by the mixing model. The Delta has long been considered a tidal freshwater marsh region, but only peat samples from Franks Wetland and Bacon Channel Island have shown a consistently fresh signal (<0.5 ppt) through time. Therefore, the eastern Delta, which occurs upstream from Bacon Channel Island along the San Joaquin River and its

Full Text Available Este ensayo contempla las miserias de la vida académica en las Research Universities norteamericanas y propone un programa de regeneración intelectual que recupere las tradiciones esclarecidas de la historia moderna de la humanidad. Así, la distopía real de la actual vida académica se contrasta con la utopía esclarecida que Francis Bacon plantea en su Nova Atlantis. La tesis central de este ensayo es que para regenerar la vida intelectual hay que recuperar los ideales universales del esclarecimiento y generar nuevos espacios no académicos para la expresión, tanto científica como artística, de una conciencia humana coherente, íntegra y solidaria. This essay considers the miseries of academic life in the Research Universities of North America and proposes a program for intellectual regeneration that is based in the enlightened traditions of modern history. As such, the dystopian reality of current academic life is here contrasted with the enlightened utopia that Francis Bacon presents in his New Atlantis. The main argument of this essay is that in order to regenerate intellectual life, it is necessary to recuperate the universal ideals of the enlightenment and generate new non-academic spaces for the expression, as much scientific as artistic, of a coherent human consciousness that unifies the expansion of knowledge to the bettermentof life.

Microsatellite markers in avocado (Persea americana Mill.): genealogical relationships among cultivated avocado genotypes.

Science.gov (United States)

Ashworth, V E T M; Clegg, M T

2003-01-01

Twenty-five microsatellite markers uniquely differentiated 35 avocado cultivars and two wild relatives. Average heterozygosity was high (60.7%), ranging from 32% in P. steyermarkii to 84% in Fuerte and Bacon. In a subset of 15 cultivars, heterozygosity averaged 63.5% for microsatellites, compared to 41.8% for restriction fragment length polymorphisms (RFLPs). A neighbor-joining tree, according to average shared allele distances, consisted of three clusters likely corresponding to the botanical races of avocado and intermediate clusters uniting genotypes of presumably racially hybrid origin. Several results were at odds with existing botanical assignments that are sometimes rendered difficult by incomplete pedigree information, the complexity of the hybrid status (multiple backcrossing), or both. For example, cv. Harvest clustered with the Guatemalan race cultivars, yet it is derived from the Guatemalan x Mexican hybrid cv. Gwen. Persea schiedeana grouped with cv. Bacon. The rootstock G875 emerged as the most divergent genotype in our data set. Considerable diversity was found particularly among accessions from Guatemala, including G810 (West Indian race), G6 (Mexican race), G755A (hybrid Guatemalan x P. schiedeana), and G875 (probably not P. americana). Low bootstrap support, even upon exclusion of (known) hybrid genotypes from the data matrix, suggests the existence of ancient hybridization or that the botanical races originated more recently than previously thought.

Technological feasibility of preserving meat, poultry and fish products by using a combination of conventional additives, mild heat treatment and irradiation

International Nuclear Information System (INIS)

1981-01-01

Radappertization is particularly applicable to precooked meat, poultry, fin fish, and shellfish, as well as to dry foods, animal feed, and spices. The resulting radappertized products are free from food spoilage microorganisms and organisms of public health significance, including the pathogens such as C. botulinum, salmonellae, trichinae, etc. The radappertized products can be stored without refrigeration for long periods (years), the limiting factor being the integrity of the primary packaging material. Irradiation sterilization of cured meats allows complete elimination or a drastic reduction of incoming nitrite to the levels needed only for characteristic colour and flavour of the items while providing protection against C. botulinum by irradiation. The irradiated-cured products with the low levels of added nitrite are free from residual nitrite and nitrosamines, including nitrosopyrrolidine in fried bacon. In recent co-operative research with the US Department of Agriculture, it was shown that irradiation also destroys pre-formed nitrosamines in bacon. The technology of the process was developed by the US National Food Irradiation Program and the US Army from 1953 to 1980. The US Army spearheaded the development of this new technology to the point where the food irradiation potentials have become meaningful within the broad scope of national and international interests. Therefore, it was highly appropriate that, effective 1 October 1980, the responsibility for the programme at this stage was transferred to the US Department of Agriculture which has been designated as the leading agency for the US Federal food and nutrition programmes

By counting and measuring the major ova of breeding birds at autopsy and combining these data with time intervals between ovipositions, rough estimates have been made of the time required to form yolk in some non-captive birds (King 1973). Direct studies have been made in domestic fowl (Gallus gallus var. domesticus; Gilbert 1972), turkeys (Meleagris galloparvo; Bacon and Cherms 1968), and Common quail (Coturnix coturnix; Bacon and Koontz 1971), by feeding the birds a capsule containing dye each day, and counting dye rings in the yolks after the eggs have been hardcooked. Recently developed methods of fixing and staining eggs have revealed differences in yolk deposited during day and night, thus permitting another estimation of the number of days during which yolk was deposited, and without direct contact with the female (Grau 1976). In eggs from chickens and quail that have been fed dyes, yolk that stained darkly with dichromate was shown to be deposited during the active daytime feeding periods, while pale-staining yolk was deposited during the night. Thus, pairs of light and dark rings, which together take a day to be deposited, may be counted to estimate time of yolk formation.In the present study we have applied the yolk ring method of estimating the number of days during which the bulk of the yolk is deposited around the central white core (Grau 1976) to the eggs of some shorebirds, gulls, terns and alcids.

Safety and sensory aspects of nitrite alternatives in meat curing

International Nuclear Information System (INIS)

Shahidi, F.; Pegg, R.B.

1991-01-01

The use of nitrite to cure meats (especially bacon) is viewed as undesirable, because it leads to the formation of carcinogenic nitrosamines. The amount of nitrite (10-40 ppm) associated with the cured colour and flavour is fairly harmless, and it is the larger amount, (100-200 ppm) added to preserve the meat, which is potentially harmful. This article reviews various preservatives which can be used in combination with low concentrations of nitrate. The authors consider that the use of lactate, of alternatively radiation sterilization, offers the best safe alternative to nitrate

The formation of mutagens in the major cooked protein-rich foods in the US diet was studied in the Ames Salmonella typhimurium test. The nine protein-rich foods most commonly eaten in the USA--ground beef, beef steak, eggs, pork chops, fried chicken, pot-roasted beef, ham, roast beef and bacon--were examined for their mutagenicity towards S. typhimurium TA1538 after normal 'household' cooking (deep frying, griddle/pan frying, baking/roasting, broiling, stewing, braising or boiling at 100-475/sup 0/C). Well-done fried ground beef, beef steak, ham, pork chops and bacon showed significant mutagen formation. For chicken and beef steak high-temperature broiling produced the most mutagenicity, followed by baking/roasting and frying. Stewing, braising and deep frying produced little mutagen. Eggs andd egg products produced mutagens only after cooking at high temperatures (the yolk to a greater extent than the white). Commercially cooked hamburgers showed a wide range of mutagenic activity. We conclude that mutagen formation following cooking of protein-containing foods is a complex function of food type, cooking time and cooking temperature. It seems clear that all the major protein-rich foods if cooked to a well-done state on the griddle (eggs only at temperature above 225/sup 0/C) or by broiling will contain mutagens detectable by the Ames/Salmonella assay. This survey is a step towards determining whether any human health hazard results from cooking protein-rich foods. Further testing in both short- and long-term genotoxicity bioassays and carcinogenesis assays are needed before any human risk extrapolations can be made.

Geologic Map of Mount Mazama and Crater Lake Caldera, Oregon

Science.gov (United States)

Bacon, Charles R.

2008-01-01

Crater Lake partly fills one of the most spectacular calderas of the world, an 8-by-10-km basin more than 1 km deep formed by collapse of the volcano known as Mount Mazama (fig. 1) during a rapid series of explosive eruptions about 7,700 years ago. Having a maximum depth of 594 m, Crater Lake is the deepest lake in the United States. Crater Lake National Park, dedicated in 1902, encompasses 645 km2 of pristine forested and alpine terrain, including the lake itself, virtually all of Mount Mazama, and most of the area of the geologic map. The geology of the area was first described in detail by Diller and Patton (1902) and later by Williams (1942), whose vivid account led to international recognition of Crater Lake as the classic collapse caldera. Because of excellent preservation and access, Mount Mazama, Crater Lake caldera, and the deposits formed by the climactic eruption constitute a natural laboratory for study of volcanic and magmatic processes. For example, the climactic ejecta are renowned among volcanologists as evidence for systematic compositional zonation within a subterranean magma chamber. Mount Mazama's climactic eruption also is important as the source of the widespread Mazama ash, a useful Holocene stratigraphic marker throughout the Pacific Northwest, adjacent Canada, and offshore. A detailed bathymetric survey of the floor of Crater Lake in 2000 (Bacon and others, 2002) provides a unique record of postcaldera eruptions, the interplay between volcanism and filling of the lake, and sediment transport within this closed basin. Knowledge of the geology and eruptive history of the Mount Mazama edifice, greatly enhanced by the caldera wall exposures, gives exceptional insight into how large volcanoes of magmatic arcs grow and evolve. Lastly, the many smaller volcanoes of the High Cascades beyond the limits of Mount Mazama are a source of information on the flux of mantle-derived magma through the region.

Full Text Available The concepts of spirit and spiritual immutation, although widely neglected, is of great interest for the understanding of Aquinas' theory of perception. In this article it will be argued that on historical as well as systematic grounds in Aquinas the concept of spiritus is ontologically ambiguous being the main question whether it has to be conceived of as something mainly material or immaterial. The ambivalence becomes especially obvious in his treatment of spiritual immutation, A brief outlook to Albert the Great and Roger Bacon aims to show that in the 13th century there were in fact theoretical alternatives to Aquinas' explanation of perceptual processes.

Innovations in health and agriculture have greatly enriched lives. But does this experience apply to all countries? If the best proof is experience, then what can be said authoritatively about the effects of using IP systems wisely in developing countries? Copyright © 2010 Elsevier B.V. All rights reserved.

The advancement of solar-electric propulsion (SEP) technologies and larger, light-weight solar arrays offer a tremendous advantage to Mars orbiters in terms of both mass and timeline flexibility. These advantages are multiplied for round-trip orbiters (e.g. potential Mars sample return) where a large total Delta V would be required. In this paper we investigate the mission design characteristics of mission concepts utilizing various combinations and types of SEP thrusters, solar arrays, launch vehicles, launch dates, arrival dates, etc. SEP allows for greater than 50% more mass delivered and launch windows of months to years. We also present the SEP analog to the ballistic Porkchop plot - the "Bacon" plot.

In contrast to tobacco, alcohol, and other consumer products associated with health risks, we know very little about how firearm manufacturers advertise their products. The authors examined advertisements for firearms in all 27 ad-accepting magazines listed in Bacon's Magazine Directory "guns and shooting" category. Sixty-three manufacturers spent an estimated $1,195,680 on firearm advertising during the month studied. Annual advertising costs ranged widely; manufacturers spent an estimated $28.16 in advertising per firearm produced. Firearms generally were presented as a part of a lifestyle. Self-protection was noted infrequently in the advertisements. By contrast, attributes of the gun, typically technological characteristics, were noted in almost every advertisement.

Necessidade, objetividade e o paradoxo metafísico do conhecimento científico Necessity, objectivity, and the metaphysical paradox of scientific knowledge

Full Text Available A racionalidade científica moderna, buscando superar a fundamentação metafísica do conhecimento objetivo, toma a experiência do fato particular como a atualização de leis dadas a priori na mente humana ou na natureza, constituindo, paradoxalmente, uma nova e 'intransparente' metafísica. Entre as críticas contemporâneas a esta forma de pensar e fazer ciência, delineia-se uma compreensão construtivista, segundo a qual o fato particular e seu conhecimento objetivo resultam de relações circunstanciais entre o homem e seu mundo. Revisitando alguns dos principais fundadores da ciência ocidental, como Aristóteles, Bacon, Descartes, Leibniz, Kant, Newton e Stuart Mill, este ensaio hermenêutico procura explorar a participação do metaconceito de 'necessidade' nessa dialética do conhecimento, interpretando, em termos epistemológicos, seu papel na construção e hipóstase da racionalidade científica moderna.Modern scientific rationality, seeking to move beyond the metaphysical foundations of objective knowledge, takes the experience of a particular fact to be the actual expression of prior laws of the human mind or of nature, thereby paradoxically constituting a new, 'invisible' metaphysics. Among contemporary critiques of this way of 'thinking and doing science', a constructivist understanding is gaining outline; according to this conception, a particular fact and objective knowledge thereof derive from circumstantial relations between human beings and their world. Revisiting some of the main founders of Western science, such as Aristotle, Bacon, Descartes, Leibniz, Kant, Newton, and Stuart Mill, this hermeneutic essay explores the participation of the meta-concept of 'necessity' within this dialectic of knowledge and, in epistemological terms, interprets its role in the construction and hypostatization of modern scientific rationality.

Historical and social contexts for scientific writing and use of passive voice: Toward an undergraduate science literacy course

Science.gov (United States)

Ding, Dan Xiong

The passive voice is a major stylistic feature of modern scientific discourse, but such a feature did not dominate scientific writing until the 1890s. It has its roots in the philosophical thoughts of experimental science of Francis Bacon and his followers such as Thomas Sprat and John Locke. In the early seventeenth century. Bacon called for a new science that emphasized collective knowledge of nature. Such a science was a cooperative and public enterprise in which scientists should work as a group to advance knowledge of nature. When science was moving gradually toward a public enterprise from the early seventeenth century, the passive voice gradually replaced the active voice in science writing as a dominant stylistic feature. The passive voice in scientific writing is thus historically and socially conditioned. Scientists take advantage of the linguistic functions of the passive voice to serve their rhetorical and pragmatic purposes such as presenting experiments as they are for others to reproduce and verify the results. It embodies two major conventions of scientific communities: (1) science is a public enterprise and (2) it is also a cooperative venture. Other conventions are related to these two: the collective authority of an scientific community is above the personal authority of any one individual scientist; science is not an infallible force, so any research result needs to be verified by a scientific community before it becomes knowledge; scientists use passive voice to approach their writing to make it appear as if it were objective; and science is a human profession. Therefore, we need to teach science students to use the passive voice, and more importantly, why and when to use it. We should emphasize writing practice to have students' see that they use passives rhetorically to present experimental processes, materials and methods.

For most of prepackaged foods a 10 kGy radiation dose is considered the maximum dose needed; however, the commercially available and practically accepted packaging materials must be suitable for such application. This work describes the application of ionizing radiation on several packaged food items, using 5 dehydrated food items, 5 ready-to-eat meals and 5 ready-to-eat food items irradiated in a 60 Co gamma source with a 3 kGy dose. The quality evaluation of the irradiated samples was performed 2 and 8 months after irradiation. Microbiological analysis (bacteria, fungus and yeast load) was performed. The sensory characteristics were established for appearance, aroma, texture and flavor attributes were also established. From these data, the acceptability of all irradiated items was obtained. All ready-to-eat food items assayed like manioc flour, some pâtés and blocks of raw brown sugar and most of ready-to-eat meals like sausages and chicken with legumes were considered acceptable for microbial and sensory characteristics. On the other hand, the dehydrated food items chosen for this study, such as dehydrated bacon potatoes or pea soups were not accepted by the sensory analysis. A careful dose choice and special irradiation conditions must be used in order to achieve sensory acceptability needed for the commercialization of specific irradiated food items. - Highlights: ► We applied gamma radiation on several kinds of packaged food items. ► Microbiological and sensory analyses were performed 2 and 8 months after irradiation. ► All ready-to-eat food items assayed were approved for microbial and sensory characteristics. ► Most ready-to-eat meals like sausages and chicken with legumes were also acceptable. ► Dehydrated bacon potatoes or pea soups were considered not acceptable.

The concentrations of heterocyclic aromatic amines (HAAs) were determined, by liquid chromatography-electrospray ionization/tandem mass spectrometry (LC-ESI-MS/MS), in 26 samples of beef, pork, and chicken cooked to various levels of doneness. The HAAs identified were 2-amino-3-methylimidazo[4,5- f]quinoline, 2-amino-1-methylimidazo[4,5- b]quinoline, 2-amino-1-methylimidazo[4,5- g]quinoxaline (I gQx), 2-amino-3-methylimidazo[4,5- f]quinoxaline, 2-amino-1,7-dimethylimidazo[4,5- g]quinoxaline (7-MeI gQx), 2-amino-3,8-dimethylimidazo[4,5- f]quinoxaline, 2-amino-1,6-dimethyl-furo[3,2- e]imidazo[4,5- b]pyridine, 2-amino-1,6,7-trimethylimidazo[4,5- g]quinoxaline, 2-amino-3,4,8-trimethylimidazo[4,5- f]quinoxaline, 2-amino-1,7,9-trimethylimidazo[4,5- g]quinoxaline, 2-amino-1-methyl-6-phenylimidazo[4,5- b]pyridine (PhIP), 2-amino-9 H-pyrido[2,3- b]indole, and 2-amino-3-methyl-9 H-pyrido[2,3- b]indole. The concentrations of these compounds ranged from chicken (up to 305 microg/kg), broiled bacon (16 microg/kg), and pan-fried bacon (4.9 microg/kg). 7-MeI gQx was the most abundant HAA formed in very well done pan-fried beef and steak, and in beef gravy, at concentrations up to 30 microg/kg. Several other linear tricyclic ring HAAs containing the I gQx skeleton are formed at concentrations in cooked meats that are relatively high in comparison to the concentrations of their angular tricyclic ring isomers, the latter of which are known experimental animal carcinogens and potential human carcinogens. The toxicological properties of these recently discovered I gQx derivatives warrant further investigation and assessment.

Paleotempestological chronology developed from gas ion source AMS analysis of carbonates determined through real-time Bayesian statistical approach

Is a small quantity of high-precision ages more robust than a higher quantity of lower-precision ages for sediment core chronologies? AMS Radiocarbon ages have been available to researchers for several decades now, and precision of the technique has continued to improve. Analysis and time cost is high, though, and projects are often limited in terms of the number of dates that can be used to develop a chronology. The Gas Ion Source at the National Ocean Sciences Accelerator Mass Spectrometry Facility (NOSAMS), while providing lower-precision (uncertainty of order 100 14C y for a sample), is significantly less expensive and far less time consuming than conventional age dating and offers the unique opportunity for large amounts of ages. Here we couple two approaches, one analytical and one statistical, to investigate the utility of an age model comprised of these lower-precision ages for paleotempestology. We use a gas ion source interfaced to a gas-bench type device to generate radiocarbon dates approximately every 5 minutes while determining the order of sample analysis using the published Bayesian accumulation histories for deposits (Bacon). During two day-long sessions, several dates were obtained from carbonate shells in living position in a sediment core comprised of sapropel gel from Mangrove Lake, Bermuda. Samples were prepared where large shells were available, and the order of analysis was determined by the depth with the highest uncertainty according to Bacon. We present the results of these analyses as well as a prognosis for a future where such age models can be constructed from many dates that are quickly obtained relative to conventional radiocarbon dates. This technique currently is limited to carbonates, but development of a system for organic material dating is underway. We will demonstrate the extent to which sacrificing some analytical precision in favor of more dates improves age models.

The Nursing Process

1978-09-01

Full Text Available The essence of the nursing process can be summed up in this quotation by Sir Francis Bacon: “Human knowledge and human powers meet in one; for where the cause is not known the effect cannot be produced.” Arriving at a concise, accurate definition of the nursing process was, for me, an impossible task. It is altogether too vast and too personal a topic to contract down into a niftylooking, we-pay-lip-service-to-it cliché. So what I propose to do is to present my understanding of the nursing process throughout this essay, and then to leave the reader with some overall, general impression of what it all entails.

Full Text Available In this text, spatiality will be discussed from a philosophical point of view, in examining the positions of Descartes and Husserl. On the one hand, the philosophy of Descartes marks the beginning of the modern era. Next to Francis Bacon, he is the one to pave the way for the upcoming sciences, especially physics, by an analytical geometry that roots in his philosophy. On the other hand, Husserl shall be examined,a quite different approach to spatiality than the one employed by Descartes. Because Husserl’s phenomenology centers upon the analysis of experience,intending that the objects themselves shall “tell” us what they are. Both approaches became influential for attempts to comprehend spatiality, since other conceptions to follow are referring to them.

Volta designed his pile by associating two different metals and liquid conducting electricity. He recognized the possibility of increasing the "voltage" by placing cells in series (a pile). This invention led to a wonderful development of science and technology, including the concept of fuel cell in 1839 by GROVE. But efficient research began only in the 20th century after the development of electrochemical thermodynamics by Nemst. His assistants conducted research on fuel cell designed by Bacon before world warII, developed NASA for the Apollo space flights. Research for effecient and clean electricity generation has led to the defferent kinds of fuel cells now under development (APC, PAPC, PAMPC, MCPC and SOPC) which will be briefly described with their applications.

CSciBox is an integrated software system for age modeling of paleoenvironmental records. It incorporates an array of data-processing and visualization facilities, ranging from 14C calibrations to sophisticated interpolation tools. Using CSciBox's GUI, a scientist can build custom analysis pipelines by composing these built-in components or adding new ones. Alternatively, she can employ CSciBox's automated reasoning engine, Hobbes, which uses AI techniques to perform an in-depth, autonomous exploration of the space of possible age-depth models and presents the results—both the models and the reasoning that was used in constructing and evaluating them—to the user for her inspection. Hobbes accomplishes this using a rulebase that captures the knowledge of expert geoscientists, which was collected over the course of more than 100 hours of interviews. It works by using these rules to generate arguments for and against different age-depth model choices for a given core. Given a marine-sediment record containing uncalibrated 14C dates, for instance, Hobbes tries CALIB-style calibrations using a choice of IntCal curves, with reservoir age correction values chosen from the 14CHRONO database using the lat/long information provided with the core, and finally composes the resulting age points into a full age model using different interpolation methods. It evaluates each model—e.g., looking for outliers or reversals—and uses that information to guide the next steps of its exploration, and presents the results to the user in human-readable form. The most powerful of CSciBox's built-in interpolation methods is BACON, a Bayesian sedimentation-rate algorithm—a powerful but complex tool that can be difficult to use. Hobbes adjusts BACON's many parameters autonomously to match the age model to the expectations of expert geoscientists, as captured in its rulebase. It then checks the model against the data and iteratively re-calculates until it is a good fit to the data.

Technological Feasibility of Preserving Meat, Poultry and Fish Products by Using a Combination of Conventional Additives, Mild Heat Treatment and Irradiation

Radappertization, or irradiation sterilization of meats and other protein foods (poultry, seafoods) is a new processing method applicable to pre-cooked (enzyme inactivated) foods that are hermetically sealed (either in metal cans, flexible pouches, or metal or plastic trays) and involves irradiation to sterilizing doses of either gamma rays (from a cobalt-60 or caesium-137 source) or by X-rays and electrons. The process is particularly applicable to pre-cooked meat, poultry, fin fish, and shellfish, as well as to dry foods, animal feed, and spices. The resulting radappertized products are free from food spoilage microorganisms and organisms of public health significance, including the pathogens such as C. botulinum, salmonellae, trichinae, etc. The radappertized products can be stored without refrigeration for long periods (years), the limiting factor being the integrity of the primary packaging material. Irradiation sterilization of cured meats allows complete elimination or a drastic reduction of incoming nitrite to the levels needed only for characteristic colour and flavour of the items while providing protection against C. botulinum by irradiation. The irradiated-cured products with the low levels of added nitrite are free from residual nitrite and nitrosamines, including nitrosopyrrolidine in fried bacon. In recent co-operative research with the US Department of Agriculture, it was shown that irradiation also destroys pre-formed nitrosamines in bacon. The technology of the process was developed by the US National Food Irradiation Program and the US Army from 1953 to 1980. The US Army spearheaded the development of this new technology to the point where the food irradiation potentials have become meaningful within the broad scope of national and international interests. Therefore, it was highly appropriate that, effective 1 October 1980, the responsibility for the programme at this stage was transferred to the US Department of Agriculture which has been

Slim by design: serving healthy foods first in buffet lines improves overall meal selection.

Directory of Open Access Journals (Sweden)

Brian Wansink

Full Text Available OBJECTIVE: Each day, tens of millions of restaurant goers, conference attendees, college students, military personnel, and school children serve themselves at buffets--many being all-you-can-eat buffets. Knowing how the food order at a buffet triggers what a person selects could be useful in guiding diners to make healthier selections. METHOD: The breakfast food selections of 124 health conference attendees were tallied at two separate seven-item buffet lines (which included cheesy eggs, potatoes, bacon, cinnamon rolls, low-fat granola, low-fat yogurt, and fruit. The food order between the two lines was reversed (least healthy to most healthy, and vise-versa. Participants were randomly assigned to choose their meal from one line or the other, and researchers recorded what participants selected. RESULTS: With buffet foods, the first ones seen are the ones most selected. Over 75% of diners selected the first food they saw, and the first three foods a person encountered in the buffet comprised 66% of all the foods they took. Serving the less healthy foods first led diners to take 31% more total food items (p<0.001. Indeed, diners in this line more frequently chose less healthy foods in combinations, such as cheesy eggs and bacon (r = 0.47; p<0.001 or cheesy eggs and fried potatoes (r= 0.37; p<0.001. This co-selection of healthier foods was less common. CONCLUSIONS: Three words summarize these results: First foods most. What ends up on a buffet diner's plate is dramatically determined by the presentation order of food. Rearranging food order from healthiest to least healthy can nudge unknowing or even resistant diners toward a healthier meal, helping make them slim by design. Health-conscious diners, can proactively start at the healthier end of the line, and this same basic principle of "first foods most" may be relevant in other contexts - such as when serving or passing food at family dinners.

Seventeenth- and eighteenth-century commentators on the chemical composition of the brain.

Sourkes, T L

The period between 1600 and 1800 was one of great change in the history of science, generally, and in the history of chemistry, specifically. It opened with Francis Bacon's visionary recognition of the benefits to mankind that would accrue from the expansion of scientia and closed with the overthrow of the phlogiston hypothesis. New chemical knowledge resulted from the efforts of the alchemists, especially in Paracelsians, and of the phlogistic philosophers, some of it recorded by writers of magic books (Thorndike, 1958; Camporesi, 1989). The authors of these works reflected 'the general mentality ... imbued with magic, occult beliefs, unreal suggestions, 'voices', and 'rumours', ... 'errors' and 'prejudices'. In respect to brain chemistry there appeared, beside the fantastic, elements of fact that characterise this period as embracing the 'pre-history' of neurochemistry.

Full Text Available This article continues my earlier work of reading Jung with Lacan. This article will develop Zizek’s work on Lacan’s concept of objet petit a by relating it to a phenomenological interpretation of Jung. I use a number of different examples, including Zizek’s interpretation of Francis Bacon, Edvard Munch, Hans Holbein and Johann Gottlieb Fichte, to describe the objet petit a and its relationship to a phenomenological interpretation of complexes. By integrating other Lacanian concepts, such as subject, drive, fantasy, jouissance, gaze, desire, and ego as well as the imaginary, symbolic and Real, this work also highlights how Hegel and Heidegger can elucidate the relationship between objet petit a and complexes. Jung’s transcendent function and the Rosarium Philosophorum also elucidate the relationship between Jung and Lacan.

[The function of analogies in natural sciences, also in contrast to metaphors and models].

Science.gov (United States)

Hentschel, Klaus

2010-01-01

This introduction surveys the various functions of analogies in science, medicine and technology. The focus is on their heuristic importance. The productiveness of analogies is linked to the systematic depth and breadth of the established connections. Various examples are presented from different periods in the history of science, most notably Galileo; such late-Victorian Maxwellians as George Francis FitzGerald and Oliver Lodge; and Heinrich HERTZ and Niels BOHR. These examples are examined in terms of the specific differing temporal ranges of their claimed validities. They serve as evidence or counterevidence for various systematic analyses of analogies as put forward by various philosophers of science, most notably Francis Bacon, John Stuart Mill, Ernst Mach, Harald Høffding, Ernest Nagel, Mary Hesse and Peter Achinstein. The analytic framework for analogies supported here is what the cognitive scientist Dedre Gentner has termed structure-mapping.

La Icaria di Étienne Cabet: un’utopia letteraria del XIX secolo

José D’Assunção Barros

2017-03-01

Full Text Available This article attempts to examine the utopian literature of the nineteenth century, approaching more directly the imaginary societies devised by Étienne Cabet, in the novel titled Voyage en Icarie (1842. This more specific analysis is preceded by a brief introduction to utopian literature since the XVI century – recovering comparatively propositions of authors such as Thomas More, Campanella, Francis Bacon, Fourier, Saint-Simon, and Robert Owen –, besides a theoric discussion about the models of equality distribution, in this case considering the reflections of Norberto Bobbio and Amartya Sen on this topic. The work of Cabet is addressed in their contexts, and is justified because they concern a bridge between literature and society, since this works have aroused great interest of readers of the time and even inspired a motivation for carrying out specific utopian experiments.

The Meat City

This article investigates the emergence of the Copenhagen slaughterhouse, called the Meat City, during the late nineteenth century. This slaughterhouse was a product of a number of heterogeneous components: industrialization and new infrastructures were important, but hygiene and the significance...... of Danish bacon exports also played a key role. In the Meat City, this created a distinction between rising production and consumption on the one hand, and the isolation and closure of the slaughtering facility on the other. This friction mirrored an ambivalent attitude towards meat in the urban space: one...... where consumers demanded more meat than ever before, while animals were being removed from the public eye. These contradictions, it is argued, illustrate and underline the change of the city towards a ‘post-domestic’ culture. The article employs a variety of sources, but primarily the Copenhagen...

Pyrocarbon and its application to reactor technology

Energy Technology Data Exchange (ETDEWEB)

Nickel, H.

1974-01-15

A survey of deposition methods for pyrocarbons is given especially of the fluidized bed process for nuclear fuel kernel coating. It is shown that structures of pyrocarbons are dependent on many parameters such as deposition temperature, nature, and pressure of the pyrolysis gas, nature of the substrate, geometry of the deposition system, etc. In the fluidized bed process, a dynamic, hot wall procedure, it is possible to deposit isotropic pyrocarbon layers which are much more resistant to fast neutron irradiation than anisotrropic pyrocarbon coatings. Because of the variety of different pyrocarbons, the methods of characterization or this material are most important. It has been demonstrated that the determination of apparent density, BACON-anisotropy-factor (BAF) and apparent crystallite size is not sufficient to characterize this material. Therefore, increased efforts have been made to develop new methods.

1980-03-01

Results of a radiological survey of the inactive uranium-mill site at Durango, Colorado, conducted in April 1976, in cooperation with a team from Ford, Bacon and Davis Utah Inc., are presented together with descriptions of the instruments and techniques used to obtain the data. Direct above-ground gamma measurements and analysis of surface soil and sediment samples indicate movement of tailings from the piles toward Lightner Creek on the north and the Animas River on the east side of the piles. The concentration of 226 Ra in the former raffinate pond area is only slightly above the background level. Two structures in Durango were found to contain high concentrations of airborne radon daughters, where tailings are known to have been utilized in construction. Near-background concentrations of radon daughters were found in a well-ventilated building close to the tailings

These field-trip guides were written for the occasion of the International Association of Volcanology and Chemistry of the Earth’s Interior (IAVCEI) quadrennial scientific assembly in Portland, Oregon, in August 2017. The guide to Mount Mazama and Crater Lake caldera is an updated and expanded version of the guide (Bacon, 1989) for part of an earlier IAVCEI trip to the southern Cascade Range. The guide to Newberry Volcano describes the stops included in the 2017 field trip. Crater Lake and Newberry are the two best-preserved and most recent calderas in the Cascades Volcanic Arc. Although located in different settings in the arc, with Crater Lake on the arc axis and Newberry in the rear-arc, both volcanoes are located at the intersection of the arc and the northwest corner region of the extensional Basin and Range Province.

2013-04-01

High resolution X-ray computed tomography (CT), or microCT, is a promising and already widely used technique in various scientific fields. Also for histological purposes it has great potential. Although microCT has proven to be a valuable technique for the imaging of bone structures, the visualization of soft tissue structures is still an important challenge due to their low inherent X-ray contrast. One way to achieve contrast enhancement is to make use of contrast agents. However, contrary to light and electron microscopy, knowledge about contrast agents and staining procedures is limited for X-ray CT. The purpose of this paper is to identify useful X-ray contrast agents for soft tissue visualization, which can be applied in a simple way and are also suited for samples larger than (1 cm)(3) . And 28 chemical substances have been investigated. All chemicals were applied in the form of concentrated aqueous solutions in which the samples were immersed. First, strips of green Bacon were stained to evaluate contrast enhancement between muscle and adipose tissue. Furthermore it was also tested whether the contrast agents remained fixed in the tissue after staining by re-immersing them in water. Based on the results, 12 contrast agents were selected for further testing on postmortem mice hind legs, containing a variety of different tissues, including muscle, fat, bone, cartilage and tendons. It was evaluated whether the contrast agents allowed a clearer distinction between the different soft tissue structures present. Finally also penetration depth was measured. And 26 chemicals resulted in contrast enhancement between muscle and adipose tissue in the Bacon strips. Mercury(II)chloride (HgCl2 ), phosphotungstic acid (PTA), phosphomolybdic acid (PMA) and ammonium orthomolybdate ((NH4 )2 MoO4 ) remained fixed after re-immersion in water. The penetration tests showed that potassium iodide (KI) and sodium tungstate can be most efficiently used for large samples of the order

Full Text Available The present work aims to present the results of the application of a treatment with high hydrostatic pressure (HHP on Italian fermented and dry-cured pork products. The products used in this study were portioned cured ham, portioned bacon and salami, vacuumpackaged and produced by a single processing company. Two studies were conducted on a single batch of the three products by means of an artificial contamination with Listeria innocua as a surrogate of L. monocytogenes. In the first trial a superficial contamination was obtained by immersion for 3 min in the culture broth with a concentration of approximately 9 log cfu/mL. At the end of the inoculum step, the pieces were dred at room temperature and vacuum packaged. In the second trial 50 kg of minced pork meat were contaminated before production of salami. In both cases the inoculum contained 5 strains of L. innocua. Subsequently, in both trials, 10 samples were randomly divided into two groups of 5 pieces each: i TH group, samples treated with HHP; ii group C, control samples, not subjected to any treatment. All samples were stored at refrigeration temperature at the end of HHP treatments (if applied, and analyzed for the determination of the surface (1st trial and deep (2nd trial quantitative contamination of L. innocua. pH and aW were also determined on 3 pieces of each products belonging to group C. The difference between the medians of the log cfu/cm2 or g established between controls and treated were compared using the non-parametric test (Kruskal-Wallis test with P<0.01. In all products and in both trials the level of contamination detected in treatment groups was always significantly lower than in controls (P<0.01. In particular, in vacuum-packaged ham, bacon and salami viability logarithmic viability reductions equal to -2.29, -2.54 and -2.51 were observed, respectively. This study aimed to evaluate a not-thermal treatment on Italian cured or fermented pork products. The results of

Ethical Traceability and Communicating Food

DEFF Research Database (Denmark)

Traceability – the ability to track a product from farm to plate – is now widely used in the food sector for a range of purposes: it allows companies to improve efficiency, facilitates product recall, and helps producers flag the specific characteristics of their goods. But traceability systems...... are mainly designed and used by the people directly involved in the food chain. The people at the end of the food chain – food consumers – have little say in which attributes are traced, and can rarely access the information stored in traceability systems.

Knowledge Representation from Classification Schema to Semantic Web (I

Silvia-Adriana Tomescu

2014-01-01

Full Text Available In this essay we aim to investigate knowledge as approach of describing possible worlds through classification schema, taxonomies, ontologies and semantic web. We focus on the historical background and the methods of culture and civilization representation. In this regard, we studied the ancient concern to classify knowledge, from the biblical period when the Tree Metaphor concentrated the essence of knowledge, to the Francis Bacon classification and then Paul Otlet and we analysed the languages used in the scientific fields and then in the information science filed, emphasizing on the improvements of the ICT: hypertext and semantic web. We paid a special attention to the knowledge construction through math language and exchange standards. The reason of the approach comes from the logic and philosophic base of the knowledge representation that underline the idea that only properly structured scientific domains ensure the progress of the society.

Full Text Available The aim of this paper is to show the analogy that David Hume (1711 - 1776 makes between moral action and the mechanical movement as a clear indication of his understanding of the relationship between reason (direction and passions (force in human conduct. Stretching from Hume's moral epistemology to his social theory, the notion that carries this analogy would serve to endorse the view that the Scottish philosopher was trying to become a sort of "Newton of the moral sciences." This meant thinking about moral philosophy within the limits of nature and allowing an independent research, especially in relation to the religious tradition. Hume´s philosophy could be also a performative image of the movement, while an inseparable composition made of the impulse of the contents of sentimental trend, according to Shaftesbury and Hutcheson, and the direction of the empirical methods come from Francis Bacon and Isaac Newton.

Full Text Available I argue that European schools of thought on memory and memorization were critical in enabling growth of the scientific method. After giving a historical overview of the development of the memory arts from ancient Greece through 17th century Europe, I describe how the Baconian viewpoint on the scientific method was fundamentally part of a culture and a broader dialogue that conceived of memorization as a foundational methodology for structuring knowledge and for developing symbolic means for representing scientific concepts. The principal figures of this intense and rapidly evolving intellectual milieu included some of the leading thinkers traditionally associated with the scientific revolution; among others, Francis Bacon, Renes Descartes, and Gottfried Leibniz. I close by examining the acceleration of mathematical thought in light of the art of memory and its role in 17th century philosophy, and in particular, Leibniz’s project to develop a universal calculus.

The findings of a radiological survey of the inactive uranium-mill site at Gunnison, Colorado, conducted in May 1976, are presented. Results of surface soil sample analyses and direct gamma radiation measurements indicate limited spread of tailings off the site. The only significant above background measurements off the site were obtained in an area previously covered by the tailings pile. There was little evidence of contamination of the surface or of unconfined groundwater in the vicinity of the tailings pile; however, the hydrologic conditions at the site indicate a potential for such contamination. The concentration of 226 Ra in all water samples except one from the tailings pile was well below the concentration guide for drinking water. The subsurface distribution of 226 Ra in 14 bore holes located on and around the tailings pile was calculated from gamma ray monitoring data obtained jointly with Ford, Bacon and Davis Utah Inc

It is not so well known that measurement-free quantum error correction protocols can be designed to achieve fault-tolerant quantum computing. Despite their potential advantages in terms of the relaxation of accuracy, speed, and addressing requirements, they have usually been overlooked since they are expected to yield a very bad threshold. We show that this is not the case. We design fault-tolerant circuits for the 9-qubit Bacon-Shor code and find an error threshold for unitary gates and preparation of p((p,g)thresh)=3.76×10(-5) (30% of the best known result for the same code using measurement) while admitting up to 1/3 error rates for measurements and allocating no constraints on measurement speed. We further show that demanding gate error rates sufficiently below the threshold pushes the preparation threshold up to p((p)thresh)=1/3.

[William Harvey revisited ].

Science.gov (United States)

Steinke, Hubert

2015-07-01

William Harvey's discovery of the circulation of the blood is often described as a product of the Scientific Revolution of the Seventeenth Century. Modern research has, however, shown thatHarvey followed the Aristotelian research tradition and thus tried to reveal the purpose of the organs through examination of various animals. His publication of 1628 has to be read as an argument of natural philosophy, or, more precisely, as a series of linked observations, experiments and philosophical reasonings from which the existence of circulation has to be deduced as a logical consequence. Harvey did not consider experiments as superior to philosophical reasoning nor intended he to create a new system of medicine. He believed in the vitality of the heart and the blood and rejected Francis Bacon's empirism and the mechanistic rationalism of Descartes. Harvey's contribution and originality lied less in his single observations and experiments but in the manner how he linked them with critical reasoning and how he accepted, presented and defended the ensuing radical findings.

When Knowledge Isn't Power: Science, Technology, and the Environment in the 21st Century

2012-12-01

Ever since Sir Francis Bacon coined the adage, scientists have believed that "knowledge is power," but this presupposes that people are willing to embrace knowledge. Today, a significant proportion of the American public rejects the scientific evidence of climate change, and many of these Americans are highly educated, so their views cannot be attributed to scientific illiteracy or misunderstanding. Historical evidence shows that resistance to scientific evidence of climate change--like the earlier resistance to the evidence of acid rain, the ozone hole, and the harms of tobacco use--is rooted in intellectual commitments to freedom, individualism, and the power of the free market to protect political freedom while delivering goods and services. Therefore, good public policy is not likely to be achieved by producing more science, better science, or communicating that science more effectively. Rather, it suggests that effective public policy must acknowledge these commitments and concerns, and offer solutions that are not perceived to threaten the American way of life.

Baconsche Tatsachen

Lorraine Daston

2002-01-01

Full Text Available Not only facts as words and concepts, but also facts as a form of experience have a history. The origins of the scientific fact as a category of experience lie in the legal fact, particularly in the work of the English jurist and natural philosopher Francis Bacon (1561-1626. The category of the fact, as a bare statement of that which is the case, unembellished by inference, interpretation, or generalization, was the creation of early modern lawyers, and then eagerly taken up by historians, natural philosophers, and even theologians--first in English, then in French, and still later in German. Baconian facts forged a new kind of scientific experience, with distinctive objects, practices, and textures. The legal distinction between matters of fact and matters of law seemed to many seventeenth-century natural philosophers to be eminently useful in driving a wedge between observations and hypotheses, between data and conjecture, especially for controversial issues.

The body of the soul. Lucretian echoes in the Renaissance theories on the psychic substance and its organic repartition.

Science.gov (United States)

Tutrone, Fabio

2014-01-01

In the 16th and 17th centuries, when Aristotelianism still was the leading current of natural philosophy and atomistic theories began to arise, Lucretius' De Rerum Natura stood out as an attractive and dangerous model. The present paper reassesses several relevant aspects of Lucretius' materialistic psychology by focusing on the problem of the soul's repartition through the limbs discussed in Book 3. A very successful Lucretian image serves as flu rouge throughout this survey: the description of a snake chopped up, with its pieces moving on the ground (Lucretius DRN 1969, 3.657-669). The paper's first section sets the poet's theory against the background of ancient psychology, pointing out its often neglected assimilation of Aristotelian elements. The second section highlights the influence of De Rerum Natura and its physiology of the soul on Bernardino Telesio, Agostino Doni and Francis Bacon, since all of these authors engage in an original recombination of mechanical and teleological explanations.

Różewicz about himself as someone else

Full Text Available It seems that Tadeusz Różewicz’s poem titled Francis Bacon or Diego Velazquez in a Dentist’s Chair is dedicated to the works of the author of Studies of Crucifixion. In fact, Różewicz writes about the impression that Bacon’s art left on him when he saw it in galleries and museums. This poem is also about fascination. Contrary to what may seem intuitive, it is not an attempt to describe the poet’s own way of interpreting these works; and even if so, this is only true to a limited extent. For Różewicz, Bacon’s works were just a pretext to look at himself, especially at his own early poems, from a distance – from a somewhat ironic distance. In this way the poet is able to present himself as “the other”, thus referring to the title of Paul Ricoeur’s book.

2008-03-01

Science and philosophy have a very long history, dating back at least to the 16th and 17th centuries, when the first scientist-philosophers, such as Bacon, Galilei, and Newton, were beginning the process of turning natural philosophy into science. Contemporary relationships between the two fields are still to some extent marked by the distrust that maintains the divide between the so-called "two cultures." An increasing number of philosophers, however, are making conceptual contributions to sciences ranging from quantum mechanics to evolutionary biology, and a few scientists are conducting research relevant to classically philosophical fields of inquiry, such as consciousness and moral decision-making. This article will introduce readers to the borderlands between science and philosophy, beginning with a brief description of what philosophy of science is about, and including a discussion of how the two disciplines can fruitfully interact not only at the level of scholarship, but also when it comes to controversies surrounding public understanding of science.

Summary of the engineering assessment of inactive uranium mill tailings, Spook Site, Converse County, Wyoming

International Nuclear Information System (INIS)

1981-10-01

Ford, Bacon, Davis Utah Inc. has reevaluated the Spook site in order to revise the December 1977 engineering assessment of the problems resulting from the existence of radioactive uranium mill tailings 48 mi northeast of Casper, in Converse County, Wyoming.

Hotson, J.; Stacey, A.; Nair, S.

1980-07-01

The basic methodology incorporated in the POPFOOD computer code is described, which may be used to calculate equilibrium collective dose rates associated with continuous atmospheric releases and arising from consumption of a broad range of food products. The standard data libraries associated with the code are also described. These include a data library, based on the 1972 agricultural census, describing the spatial distribution of production, in England, Wales and Scotland, of the following food products: milk; beef and veal; pork bacon and ham; poultrymeat; eggs; mutton and lamb; root vegetables; green vegetables; fruit; cereals. Illustrative collective dose calculations were made for the case of 1 Ci per year emissions of 131 I, tritium and 14 C from a typical rural UK site. The calculations indicate that the ingestion pathway results in a greater collective dose than that via inhalation, with the contributions from consumption of root and green vegetables, and cereals being of comparable significance to that from liquid milk consumption, in all three cases.

Eerola, Susanna; Hollebekkers, Koen; Hallikainen, Anja; Peltonen, Kimmo

2007-02-01

Sample clean-up and HPLC with tandem mass spectrometric detection (LC-MS/MS) was validated for the routine analysis of acrylamide in various foodstuffs. The method used proved to be reliable and the detection limit for routine monitoring was sensitive enough for foods and drinks (38 microg/kg for foods and 5 microg/L for drinks). The RSDs for repeatability and day-to-day variation were below 15% in all food matrices. Two hundred and one samples which included more than 30 different types of food and foods manufactured and prepared in various ways were analysed. The main types of food analysed were potato and cereal-based foods, processed foods (pizza, minced beef meat, meat balls, chicken nuggets, potato-ham casserole and fried bacon) and coffee. Acrylamide was detected at levels, ranging from nondetectable to 1480 microg/kg level in solid food, with crisp bread exhibiting the highest levels. In drinks, the highest value (29 microg/L) was found in regular coffee drinks.

Results of a radiological survey of the inactive uranium-mill site at Tuba City, Arizona, conducted in March 1976, are presented. Spread of tailings was detected in all directions by means of direct gamma measurements at 1 m above the ground and by determinations of the 226 Ra concentration in surface soil and sediment samples. In the direction toward which prevailing winds blow, the northeast, evidence of transportation of tailings was found at least 3.2 km from the tailings pile. Toward the north, south, and west, the spread was 300 to 400 m. Evidence of movement of tailings by water to offsite locations was also found. The concentration of 226 Ra in all water samples was well below the concentration guide for drinking water. The calculated subsoil distribution of 226 Ra in 14 holes, based on gamma monitoring data obtained by Ford, Bacon and Davis Utah Inc., is presented graphically and compared with available analytical data

Doan, N.V.; Tietze, H.

1995-01-01

We use Molecular Dynamics Computer Simulations to investigate defect production induced by energetic displacement cascades up to 10 keV in pure metals (Cu, Ni) and in ordered intermetallic alloys NiAl, Ni 3 Al. Various model potentials were employed to describe the many-body nature of the interactions: the RGL (Rosato-Guillope-Legrand) model was used in pure Cu and Ni simulations; the modified version of the Vitek, Ackland and Cserti potentials (due to Gao, Bacon and Ackland) in Ni 3 Al and the EAM potentials of Foiles and Daw modified by Rubini and Ballone in NiAl, Ni 3 Al were used in alloy simulations. Atomic mixing and disordering were studied into details owing to imaging techniques and determined at different phases of the cascades. Some mixing mechanisms were identified. Our results were compared with existing data and those obtained by similar Molecular Dynamics Simulations available in the literature. (orig.)

The diffident naturalist Robert Boyle and the philosophy of experiment

CERN Document Server

Sargent, Rose-Mary

2009-01-01

In a provocative reassessment of one of the quintessential figures of early modern science, Rose-Mary Sargent explores Robert Boyle's philosophy of experiment, a central aspect of his life and work that became a model for mid- to late seventeenth-century natural philosophers and for many who followed them. Sargent examines the philosophical, legal, experimental, and religious traditions-among them English common law, alchemy, medicine, and Christianity-that played a part in shaping Boyle's experimental thought and practice. The roots of his philosophy in his early life and education, in his religious ideals, and in the work of his predecessors-particularly Bacon, Descartes, and Galileo-are fully explored, as are the possible influences of his social and intellectual circle. Drawing on the full range of Boyle's published works, as well as on his unpublished notebooks and manuscripts, Sargent shows how these diverse influences were transformed and incorporated into Boyle's views on and practice of experiment.

Measuring Gravitational Flexion in ACS Clusters

Science.gov (United States)

Goldberg, David

2005-07-01

We propose measurement of the gravitational "Flexion" signal in ACS cluster images. The flexion, or "arciness" of a lensed background galaxy arises from variations in the lensing field. As a result, it is extremely sensitive to small scale perturbations in the field, and thus, to substructure in clusters. Moreover, because flexion represents gravitationally induced asymmetries in the lensed image, it is completely separable from traditional measurements of shear, which focus on the induced ellipticity of the image, and thus, the two signals may be extracted simultaneously. Since typical galaxies are roughly symmetric upon 180 degree rotation, even a small induced flexion can potentially produce a noticeable effect {Goldberg & Bacon, 2005}. We propose the measurement of substructure within approximately 4 clusters with high-quality ACS data, and will further apply a test of a new tomographic technique whereby comparisons of lensed arcs at different redshifts may be used to estimate the background cosmology, and thus place constraints on the equation of state of dark energy.

Relevance of nitrate and nitrite in dry-cured ham and their effects on aroma development

Directory of Open Access Journals (Sweden)

Flores, Mónica

2009-07-01

Full Text Available Potassium and sodium salts of nitrite (E 249 and E 250 and nitrate (E 251 and E 252 are authorised for use under certain levels in several foodstuffs such as non-heat-treated, cured and dried meat products, other cured meat products, canned meat products and bacon. The key point in the use of nitrate and nitrite as preservatives is to find a balance between ensuring the microbiological safety of the ham and keeping as low as possible the level of nitrosamines in the final product. Nitrites and nitrates are authorised as additives for dry-cured ham in the Directive 2006/52/EC of 5 July 2006 that modifies previous Council Directive 95/2/EC on food additives other than colours and sweeteners. The effect of nitrate and its reduction to nitrite in controlling the lipid oxidation process during the ham ripening is very important for the development of the characteristic cured flavour. The main benefits and drawbacks of the use of nitrites and nitrates in dry-cured ham and how these levels may affect its flavour are discussed in this manuscript.Las sales sódica y potásica del nitrito (E249 y E250 y del nitrato (E251 y E252 están autorizados para su uso en los productos cárnicos, secos, curados y no tratados por el calor, otros productos cárnicos curados, productos cárnicos enlatados y bacon. El punto esencial en el uso de nitrato y nitrito como conservantes consiste en encontrar un balance entre el aseguramiento de la seguridad microbiológica del jamón y mantener el nivel de nitrosaminas tan bajo como sea posible.

Impurity of Sulfur Layers and Magmatic Gas Scrubbing: Implications for Gas Monitoring

Science.gov (United States)

Scolamacchia, T.

2017-12-01

The evidence of bodies of elemental sulfur (Se) beneath acid crater lakes at the summit of composite active volcanoes has been recognized several decades ago (Oppenheimer and Stevenson, 1989; Christenson and Woods, 1993). But Se accumulation was already hypothesized a century ago at Kusatzu Shirane (Japan) based on the observation of sulfur spherules floating on its crater-lake (Ohashi, 1919). Since these pioneering works, other studies have focused on understanding key aspects of molten sulfur bodies, considered a feature unique of volcanic lakes. Instead, it is reasonable to assume that Se bodies occur in several volcanic settings because a) several reactions may lead to Se deposition from S-bearing gases, and b) crater-lakes, surface expressions of hydrothermal systems, are transient features. The scrubbing of several magmatic gases, some of which critical for volcano monitoring, has been attributed to ground/surface waters (Symonds et al. 2001). Nevertheless, gas scrubbing could reflect viscosity variations of impure Se within hydrothermal systems. Industrial experiments indicated that impurities (organics, H2S, ammonia, HCl, HF, HBr, HI) hinder Se polymerization at T ≥ 160ºC, allowing viscosity to remain low for long time depending on the maximum T achieved and heating rates (Bacon and Fanelli, 1943). However, a prolonged heating destroys the viscosity-modifying substances (e.g. H2Sx formed by reactions with organics, H2S, or ammonia) and dramatic Se viscosity increases occur after a certain number of heating and cooling cycles. A prolonged boiling of Se with organics was observed to release H2S, following H2Sx disruption. Some gases (e.g. SO2) do not affect Se viscosity. In volcanic environments gases such as SO2, CO2 could escape under Selow viscosity regimes. Also, halogens absence in gas emissions could be caused by their participation in reactions within S-layers causing its viscosity to remain low. More data are needed to validate the hypothesis

Tephras are important for the NZ-INTIMATE project because they link all three records comprising the composite inter-regional stratotype developed for the New Zealand climate event stratigraphy (NZ-CES). Here we firstly report new calendar ages for 24 widespread marker tephras erupted since 30,000 calendar (cal.) years ago in New Zealand to help facilitate their use as chronostratigraphic dating tools for the NZ-CES and for other palaeoenvironmental and geological applications. The selected tephras comprise 12 rhyolitic tephras from Taupo, nine rhyolitic tephras from Okataina, one peralkaline rhyolitic tephra from Tuhua, and one andesitic tephra each from Tongariro and Egmont/Taranaki volcanic centres. Age models for the tephras were obtained using three methods: (i) 14C-based wiggle-match dating of wood from trees killed by volcanic eruptions (these dates published previously); (ii) flexible depositional modelling of a high-resolution 14C-dated age-depth sequence at Kaipo bog using two Bayesian-based modelling programs, Bacon and OxCal's P_Sequence function, and the IntCal09 data set (with SH offset correction -44 ± 17 yr); and (iii) calibration of 14C ages using OxCal's Tau_Boundary function and the SHCal04 and IntCal09 data sets. Our preferred dates or calibrated ages for the 24 tephras are as follows (youngest to oldest, all mid-point or mean ages of 95% probability ranges): Kaharoa AD 1314 ± 12; Taupo (Unit Y) AD 232 ± 10; Mapara (Unit X) 2059 ± 118 cal. yr BP; Whakaipo (Unit V) 2800 ± 60 cal. yr BP; Waimihia (Unit S) 3401 ± 108 cal. yr BP; Stent (Unit Q) 4322 ± 112 cal. yr BP; Unit K 5111 ± 210 cal. yr BP; Whakatane 5526 ± 145 cal. yr BP; Tuhua 6577 ± 547 cal. yr BP; Mamaku 7940 ± 257 cal. yr BP; Rotoma 9423 ± 120 cal. yr BP; Opepe (Unit E) 9991 ± 160 cal. yr BP; Poronui (Unit C) 11,170 ± 115 cal. yr BP; Karapiti (Unit B) 11,460 ± 172 cal. yr BP; Okupata 11,767 ± 192 cal. yr BP; Konini (bed b) 11,880 ± 183 cal. yr BP; Waiohau 14,009 ± 155

In plain sight: the Chesapeake Bay crater ejecta blanket

Griscom, D. L.

2012-02-01

idealized calculation of the CBIS ejecta-blanket elevation profile minutes after the impact was carried out founded on well established rules for explosion and impact-generated craters. This profile is shown here to match the volume of the upland deposits ≥170 km from the crater center. Closer to the crater, much of the "postdicted" ejecta blanket has clearly been removed by erosion. Nevertheless the Shirley and fossil-free Bacons Castle Formations, located between the upland deposits and the CBIS interior and veneering the present day surface with units ∼10-20 m deep, are respectively identified as curtain- and excavation-phase ejecta. The neritic-fossil-bearing Calvert Formation external to the crater is deduced to be of Eocene age (as opposed to early Miocene as currently believed), preserved by the armoring effects of the overlying CBIS ejecta composed of the (distal) upland deposits and the (proximal) Bacons Castle Formation. The lithofacies of the in-crater Calvert Formation can only have resulted from inward mass wasting of the postdicted ejecta blanket, vestiges of which (i.e. the Bacons Castle and Shirley Formations) still overlap the crater rim and sag into its interior, consistent with this expectation. Because there appear to be a total of ∼10 000 km2 of CBIS ejecta lying on the present-day surface, future research should center the stratigraphic, lithologic, and petrologic properties of these ejecta versus both radial distance from the crater center (to identify ejecta from different ejection stages) and circumferentially at fixed radial distances (to detect possible anisotropies relating the impact angle and direction of approach of the impactor). The geological units described here may comprise the best preserved, and certainly the most accessible, ejecta blanket of a major crater on the Earth's surface and therefore promise to be a boon to the field of impact geology. As a corollary, a major revision of the current stratigraphic column of the M

Although Vico was admittedly disappointed by Bacon’s Exemplum tractatus, a parallel reading of this text and De uno can provide insights as to how Vico ended up having to confront a series of issues: how does the universal law project itself into history? Where does the law stem from? Is there a link between law, occasion, and utility? What are the sources and the scope of authority? How does violence affect the law? What role for religion and piety? How to devise a philology for the laws and ancient fables? Bacon’s scattered aphorisms offer glimpses into problems which find a solution in the all-encompassing order of De uno.

None

1977-10-01

Ford, Bacon and Davis Utah Inc. has performed an engineering assessment of the problems resulting from the existence of radioactive uranium mill tailings at Grand Junction, Colorado. The Phase II, Title I services include the preparation of topographic maps, the performance of core drillings and radiometric measurements sufficient to determine areas and volumes of tailings and radiation exposures of individuals and nearby populations, the investigation of site hydrology and meteorology and the evaluation and costing of alternative corrective actions. Radon gas release from the 1.9 million tons of tailings at the Grand Junction site constitutes the most significant environmental impact, although windblown tailings and external gamma radiation are also factors. The eight alternative actions presented range from millsite decontamination (Option I), to adding various depths of stabilization cover material (Options II and III), to removal of the tailings to long-term storage sites and decontamination of the present site (Options IV through VIII). Cost estimates for the eight options range from $470,000 to $18,130,000. Reprocessing the tailings for uranium recovery does not appear to be economically attractive at present.

Philosophy as Inquiry Aimed at the Absolute Knowledge

Directory of Open Access Journals (Sweden)

Ekaterina Snarskaya

2017-09-01

Full Text Available Philosophy as the absolute knowledge has been studied from two different but closely related approaches: historical and logical. The first approach exposes four main stages in the history of European metaphysics that marked out types of “philosophical absolutism”: the evolution of philosophy brought to light metaphysics of being, method, morals and logic. All of them are associated with the names of Aristotle, Bacon/Descartes, Kant and Hegel. Then these forms are considered in the second approach that defined them as subject-matter of philosophy as such. Due to their overall, comprehensive character, the focus of philosophy on them justifies its claim on absoluteness as far as philosophy is aimed at comprehension of the world’s unity regardless of the philosopher’s background, values and other preferences. And that is its prerogative since no other form of consciousness lays down this kind of aim. Thus, philosophy is defined as an everlasting attempt to succeed in conceiving the world in all its multifold manifestations. This article is to try to clarify the claim of philosophy on the absolute knowledge.

The use of sorbate and nitrite in meat processing may lead to the formation of 2-methyl-1,4-dinitro-pyrrole (DNMP), a mutagenic compound. This work was aimed at developing and validating an analytical method for the quantitation of DNMP by liquid chromatography-tandem mass spectrometry. Full validation was performed in accordance to Commission Decision 2002/657/EC and method applicability was checked in several samples of meat products. A simple procedure, with low temperature partitioning solid-liquid extraction, was developed. The nitrosation during the extraction was monitored by the N-nitroso-DL-pipecolic acid content. Chromatographic separation was achieved in 8 min with di-isopropyl-3-aminopropyl silane bound to hydroxylated silica as stationary phase. Samples of bacon and cooked sausage yielded the highest concentrations of DNMP (68 ± 3 and 50 ± 3 μg kg -1 , respectively). The developed method proved to be a reliable, selective, and sensitive tool for DNMP measurements in meat products. Copyright © 2018 Elsevier B.V. All rights reserved.

Optimizing a mobile robot control system using GPU acceleration

Tuck, Nat; McGuinness, Michael; Martin, Fred

2012-01-01

This paper describes our attempt to optimize a robot control program for the Intelligent Ground Vehicle Competition (IGVC) by running computationally intensive portions of the system on a commodity graphics processing unit (GPU). The IGVC Autonomous Challenge requires a control program that performs a number of different computationally intensive tasks ranging from computer vision to path planning. For the 2011 competition our Robot Operating System (ROS) based control system would not run comfortably on the multicore CPU on our custom robot platform. The process of profiling the ROS control program and selecting appropriate modules for porting to run on a GPU is described. A GPU-targeting compiler, Bacon, is used to speed up development and help optimize the ported modules. The impact of the ported modules on overall performance is discussed. We conclude that GPU optimization can free a significant amount of CPU resources with minimal effort for expensive user-written code, but that replacing heavily-optimized library functions is more difficult, and a much less efficient use of time.

Aroma extraction dilution analysis of Sauternes wines. Key role of polyfunctional thiols.

Bailly, Sabine; Jerkovic, Vesna; Marchand-Brynaert, Jacqueline; Collin, Sonia

2006-09-20

The aim of the present work was to investigate Sauternes wine aromas. In all wine extracts, polyfunctional thiols were revealed to have a huge impact. A very strong bacon-petroleum odor emerged at RI = 845 from a CP-Sil5-CB column. Two thiols proved to participate in this perception: 3-methyl-3-sulfanylbutanal and 2-methylfuran-3-thiol. A strong synergetic effect was evidenced between the two compounds. The former, never mentioned before in wines, and not found in the musts of this study, is most probably synthesized during fermentation. 3-Methylbut-2-ene-1-thiol, 3-sulfanylpropyl acetate, 3-sulfanylhexan-1-ol, and 3-sulfanylheptanal also contribute to the global aromas of Sauternes wines. Among other key odorants, the presence of a varietal aroma (alpha-terpineol), sotolon, fermentation alcohols (3-methylbutan-1-ol and 2-phenylethanol) and esters (ethyl butyrate, ethyl hexanoate, and ethyl isovalerate), carbonyls (trans-non-2-enal and beta-damascenone), and wood flavors (guaiacol, vanillin, eugenol, beta-methyl-gamma-octalactone, and Furaneol) is worth stressing.

A critique of the hypothesis, and a defense of the question, as a framework for experimentation.

Glass, David J

Scientists are often steered by common convention, funding agencies, and journal guidelines into a hypothesis-driven experimental framework, despite Isaac Newton's dictum that hypotheses have no place in experimental science. Some may think that Newton's cautionary note, which was in keeping with an experimental approach espoused by Francis Bacon, is inapplicable to current experimental method since, in accord with the philosopher Karl Popper, modern-day hypotheses are framed to serve as instruments of falsification, as opposed to verification. But Popper's "critical rationalist" framework too is problematic. It has been accused of being: inconsistent on philosophical grounds; unworkable for modern "large science," such as systems biology; inconsistent with the actual goals of experimental science, which is verification and not falsification; and harmful to the process of discovery as a practical matter. A criticism of the hypothesis as a framework for experimentation is offered. Presented is an alternative framework-the query/model approach-which many scientists may discover is the framework they are actually using, despite being required to give lip service to the hypothesis.

A short history of the soil science discipline

Since people have cultivated the land they have generated and created knowledge about its soil. By the 4th century most civilizations around had various levels of soil knowledge and that includes irrigation, the use of terraces to control soil erosion, methods to maintain and improve soil fertility. The early soil knowledge was largely empirical and based on observations. Many famous scientists, for example, Francis Bacon, Robert Boyle, Charles Darwin, and Leonardo da Vinci worked on soil issues. Soil science became a true science in the 19th century with the development of genetic soil science, lead by the Russian Vasilii V. Dokuchaev. In the beginning soil science had strong ties to both geology and agriculture but in the 20th century, soil science is now being applied in residential development, the planning of highways, building foundations, septic systems, wildlife management, environmental management, and many other applications. The discipline is maturing and soil science plays a crucial role in many of the current issues that confront the world like climate change, water scarcity, biodiversity and environmental degradation.

Engineering assessment of inactive uranium mill tailings, Maybell Site, Maybell, Colorado. Summary of the Phase II, Title I

International Nuclear Information System (INIS)

1977-10-01

Ford, Bacon and Davis Utah Inc. has performed an engineering assessment of the problems resulting from the existence of radioactive uranium mill tailings at Maybell, Colorado. The Phase II-Title I services include the preparation of topographic maps, the performance of core drillings sufficient to determine areas and volumes of tailings and radiometric measurements to determine radium-contaminated materials, the evaluation of resulting radiation exposures of individuals and nearby populations, the investigation of site hydrology and meteorology and the evaluation and costing of alternative corrective actions. Radon gas release from the 2.6 million tons of tailings at the Maybell site constitutes the most significant environmental impact, although windblown tailings and external gamma radiation are also factors. The three alternative actions presented range from fencing and maintenance (Option I), to placing the tailings in an open-pit mine and adding 2 ft of stabilization cover material (Option III). Cost estimates for the three options range from $250,000 to $4,520,000. Reprocessing the tailings for uranium does not appear to be economically attractive at present

Adiabatic graph-state quantum computation

Antonio, B; Anders, J; Markham, D

2014-01-01

Measurement-based quantum computation (MBQC) and holonomic quantum computation (HQC) are two very different computational methods. The computation in MBQC is driven by adaptive measurements executed in a particular order on a large entangled state. In contrast in HQC the system starts in the ground subspace of a Hamiltonian which is slowly changed such that a transformation occurs within the subspace. Following the approach of Bacon and Flammia, we show that any MBQC on a graph state with generalized flow (gflow) can be converted into an adiabatically driven holonomic computation, which we call adiabatic graph-state quantum computation (AGQC). We then investigate how properties of AGQC relate to the properties of MBQC, such as computational depth. We identify a trade-off that can be made between the number of adiabatic steps in AGQC and the norm of H-dot as well as the degree of H, in analogy to the trade-off between the number of measurements and classical post-processing seen in MBQC. Finally the effects of performing AGQC with orderings that differ from standard MBQC are investigated. (paper)

Hierarchical Bayesian models to assess between- and within-batch variability of pathogen contamination in food.

Commeau, Natalie; Cornu, Marie; Albert, Isabelle; Denis, Jean-Baptiste; Parent, Eric

2012-03-01

Assessing within-batch and between-batch variability is of major interest for risk assessors and risk managers in the context of microbiological contamination of food. For example, the ratio between the within-batch variability and the between-batch variability has a large impact on the results of a sampling plan. Here, we designed hierarchical Bayesian models to represent such variability. Compatible priors were built mathematically to obtain sound model comparisons. A numeric criterion is proposed to assess the contamination structure comparing the ability of the models to replicate grouped data at the batch level using a posterior predictive loss approach. Models were applied to two case studies: contamination by Listeria monocytogenes of pork breast used to produce diced bacon and contamination by the same microorganism on cold smoked salmon at the end of the process. In the first case study, a contamination structure clearly exists and is located at the batch level, that is, between batches variability is relatively strong, whereas in the second a structure also exists but is less marked. © 2012 Society for Risk Analysis.

Effect of combined addition of N and Nb on the high temperature behavior of a 25Cr-20Ni stainless steel

Park, In Duck; Nam, Ki Woo

2002-01-01

In order to clarify the effect of precipitates on creep strength at high temperature in 25Cr-20Ni stainless steels, threshold stress and void-hardening stress have been measured and compared each others. The value of threshold stress for high temperature, measured by stress abruptly loading test, is about 130 MPa. Threshold stress must be measured by the function of stress loading time in the combination hardening steel of solution hardening and precipitate hardening. Average diameter and inter-partial distance of precipitates from TEM microstructure can determine void-hardening stress. The value of void-hardening stress, evaluated by using Scattergood and Bacon's equation, was from 101 to 130 MPa. The ratio of average void hardening to threshold stress is 1.13 and both values are not equal. The result from analyzing the electron diffraction pattern shows that the dispersed precipitates in SUS310J1TB is NbCrN nitrides. Mechanism of the interaction between dislocations and precipitate particles in SUS310J1TB is Srolovitz mechanism, which is a gravitation-type interaction

This article compares food intake by women 35 years or older in two population-based cross-sectional studies in Rio de Janeiro, Brazil, in 1995-1996 (n = 1,014) and 2004-2005 (n = 1,001). Food intake was assessed with a food-frequency questionnaire, and nutritional status was defined according to body mass index (BMI = weight/height(2)). Prevalence of obesity (BMI 30 kg/m(2)) increased in the ten-year period (16.6% to 24%). Many high energy density (kcal/g) foods showed a statistically significant increase in the period, such as crackers, candies, bacon, sausage, and hamburger. Some high energy density items were reported less frequently: butter, mayonnaise, potato chips, and sugar. The intake of fruits, milk, beans, roots and potatoes, and meat decreased in the 10-year period. Women with more education showed a larger reduction in fruit and meat intake and a smaller reduction in fish, dairy product, and root and potato intake. Changes in prevalence of obesity were associated with numerous changes in food intake, depending on the level of schooling.

Ion mobility spectrometry after supercritical fluid chromatography

International Nuclear Information System (INIS)

Morrissey, M.A.

1988-01-01

In this work, a Fourier transform ion mobility spectrometer (FT-IMS) was constructed and evaluated as a detector for supercritical fluid chromatography (SFC). The FT-IMS provides both quantitative and qualitative data of a wide range of compounds, selective and nonselective modes of chromatographic detection, and it is compatible with a wide range of SFC mobile phases. Drift spectra are presented for a number of samples, including polymers, lipids, herbicides, antibiotics, and pharmaceuticals. The unique properties of supercritical fluids made it possible to introduce these compounds into the spectrometer. While the drift spectra presented are generally simple, showing only a quasi-molecular ion, a few are surprising complex. Examples of selective and non-selective detection demonstrate the usefulness of the detector. Examples are presented for fish oil concentrate, bacon grease extract, soil extract, and polymer mixtures. In the case of Triton X-100, a non-ionic surfactant, the FT-IMS was able to selectively detect individual oligomers in the polymer mixture. In the case of a polydimethylsilicone mixture the detector isolated a contaminant in the mixture

Hidden attraction the history and mystery of magnetism

CERN Document Server

Verschuur, Gerrit L

1996-01-01

Long one of nature''s most fascinating phenomena, magnetism was once the subject of many superstitions. Magnets were thought useful to thieves, effective as a love potion or as a cure for gout or spasms. They could remove sorcery from women and put demons to flight and even reconcile married couples. It was said that a lodestone pickled in the salt of sucking fish had the power to attract gold. Today, these beliefs have been put aside, but magnetism is no less remarkable for our modern understanding of it. In Hidden Attraction, Gerrit L. Verschuur, a noted astronomer and National Book Award nominee for The Invisible Universe, traces the history of our fascination with magnetism, from the first discovery of magnets in Greece, to state-of-the-art theories that see magnetism as a basic force in the universe. The book begins with the early debunking of superstitions by Peter Peregrinus (Pierre de Maricourt), whom Roger Bacon hailed as one of the world''s first experimental scientists (Perigrinus held that "experi...

Full Text Available In this paper, we present the characterization of six traditional meat products: smoked file, smoked bacon, pork sausages, sausage prepared from swine’s entrails, pork pastrami, sheep sausages. Organoleptic tests (the aspect and shape, the aspect of freshly cut in the section, smell, taste and consistency, physico-chemical and microbiological determinations (NTG, Salmonella, Listeria monocytogenes and Escherichia coli were performed. These analyzes are a part of quality control that must be done in order to obtain a certificate from the Ministry of Agriculture for a traditional product. After identification of H2S and starch and according to fat oxidation degree it was concluded that analyzed samples didn’t contain counterfeiters and all parameters analyzed are within the maximum limits allowed by law. Considering all the procedures for manufacturing, characteristics of raw and auxiliary materials, organoleptic properties of final products analyzed in this study, it can be concluded that analyzed meat specialties meet the requirements of Ministry Order no. 690/28.09.2004 for the traditional products certification.

Threads that guide or ties that bind: William Kirby and the essentialism story.

Science.gov (United States)

Varma, Charissa S

2009-01-01

Nineteenth-century British entomologist William Kirby is best known for his generic division of bees based on tongues and his vigorous defence of natural theology. Focusing on these aspects of Kirby's work has lead many current scholars to characterise Kirby as an "essentialist." As a result of this characterisation, many important aspects of his work, Monographia Apum Angliae (1802) have been over-looked or misunderstood. Kirby's religious devotion, for example, have lead some scholars to assume Kirby used the term "type" for connecting an ontological assumption about essences with a creationist assumption about species fixity, which I argue conceals a variety of ways Kirby employed the term. Also, Kirby frequently cautioned against organising a classification system exclusively by what he called "analytic reasoning," a style of reasoning 20th century scholars often associate with Aristotelian logic of division. I argue that Kirby's critique of analytic reasoning brought the virtues of his own methodological agenda into sharp relief. Kirby used familiar metaphors in the natural history literature--Ariadne's thread, the Eleusinian mysteries, and Bacon's bee and spider metaphors--to emphasise the virtues of building tradition and cooperation in the goals and methodological practices of 19th century British naturalists.

The present analysis aimed to investigate the changes in the reported portion sizes (PS) of foods and beverages commonly consumed by Irish adults (18-64 years) from the North South Ireland Food Consumption Survey (NSIFCS) (1997-2001) and the National Adult Nutrition Survey (NANS) (2008-10). Food PS, which are defined as the weight of food (g) consumed per eating occasion, were calculated for comparable foods and beverages in two nationally representative cross-sectional Irish food consumption surveys and were published in NSIFCS and NANS. Repeated measure mixed model analysis compared reported food PS at the total population level as well as subdivided by sex, age, BMI and social class. A total of thirteen commonly consumed foods were examined. The analysis demonstrated that PS significantly increased for five foods ('white sliced bread', 'brown/wholemeal breads', 'all meat, cooked', 'poultry, roasted' and 'milk'), significantly decreased for three ('potatoes', 'chips/wedges' and 'ham, sliced') and did not significantly change for five foods ('processed potato products', 'bacon/ham', 'cheese', 'yogurt' and 'butter/spreads') between the NSIFCS and the NANS. The present study demonstrates that there was considerable variation in the trends in reported food PS over this period.

Mining Tacitus: secrets of empire, nature and art in the reason of state.

Science.gov (United States)

Keller, Vera

2012-06-01

A new political practice, the 'reason of state', informed the ends and practices of natural study in the late sixteenth century. Informed by the study of the Roman historian Tacitus, political writers gathered 'secrets of empire' from both history and travel. Following the economic reorientation of 'reason of state' by Giovanni Botero (1544-1617), such secrets came to include bodies of useful particulars concerning nature and art collected by an expanding personnel of intelligencers. A comparison between various writers describing wide-scale collections, such as Botero, Francis Bacon (1561-1626), Jakob Bornitz (1560-1625) and Matthias Bernegger (1582-1640), reveals that seventeenth-century natural intelligencers across Europe not only were analogous to political intelligencers, but also were sometimes one and the same. Those seeking political prudence cast themselves as miners, prying precious particulars from the recesses of history, experience and disparate disciplines, including mathematics, alchemy and natural philosophy. The seventeenth-century practice of combining searches for secrets of empire, nature and art contests a frequent historiographical divide between empirical science and Tacitism or reason of state. It also points to the ways political cunning shaped the management of information for both politics and the study of nature and art.

Blind suffering: Ribera’s non-visual epistemology of martyrdom

Directory of Open Access Journals (Sweden)

Itay Sapir

2015-02-01

Full Text Available One of the oft-neglected aspects of early Baroque painting is its critical stance vis-à-vis renaissance’s ideal of pure and perfect visibility. The origins of this standpoint can be traced to the art of Caravaggio, but it is the Hispano-Neapolitan painter Jusepe de Ribera who brings it to a culmination of sorts, in a sustained pictorial quest for a novel sensorial pragmatics. Ribera’s representations of martyrdom, in particular, create a fascinating play between saints’ tactile experience of their suffering, their complex, often-deficient visual perception, and the viewer’s limited access to visual information when reconstructing the narrative on the basis of pictorial evidence. In this article, I analyse Ribera’s creation of mock-tactile textures through purely visual techniques, and the implications of such an artistic method for the hierarchy of the senses in the devotional context of Neapolitan culture in the first half of the seventeenth century. Gilles Deleuze’s analysis of Francis Bacon in The Logic of Sensation and Steven Connor’s observations on skin’s place in modern culture are brought also to bear on Ribera’s epidermal painting and its subversion of ocularcentrism.

The Dovecote Has Opened Its Eyes: Popular Conspiracy in Seventeenth-Century Italy

Carlo Ginzburg

2016-03-01

Full Text Available The hero of this essay by Calro Ginzburg is XVII-th century clown and distiller Costantino Saccardino, who also was active in the field of medical art. Accused together with his companions of secretly defiling city saint painting with excrements, Saccardino preached that religion – particularly its approach towards hell – was pure fiction and that first people were not created by God but were born out of mud. Ginzburg draws attention to the affinity between Saccardino’s heretical views (marked by the awareness of crisis and the anticipation of political, religious and cultural revolution and the diagnoses made by Galileo, Bacon, Campanella, Rosicrusarians or even Descartes. At the same time Sccardino’s sensibility is that of a professional comedian – not a great intellectual – and this is what makes his case exceptional. The case of Saccardino, who – as is demontrated by Ginzburg – had a good knowledge of libertine literature while rejecting libertine elitism, shows that in this period the relations between the high culture and the culture of the subordinated classes could include an exchange that went through a detour, mediated in various, sometimes opposing codes.

Degrees of separation as a statistical tool for evaluating candidate genes.

Science.gov (United States)

Nelson, Ronald M; Pettersson, Mats E

2014-12-01

Selection of candidate genes is an important step in the exploration of complex genetic architecture. The number of gene networks available is increasing and these can provide information to help with candidate gene selection. It is currently common to use the degree of connectedness in gene networks as validation in Genome Wide Association (GWA) and Quantitative Trait Locus (QTL) mapping studies. However, it can cause misleading results if not validated properly. Here we present a method and tool for validating the gene pairs from GWA studies given the context of the network they co-occur in. It ensures that proposed interactions and gene associations are not statistical artefacts inherent to the specific gene network architecture. The CandidateBacon package provides an easy and efficient method to calculate the average degree of separation (DoS) between pairs of genes to currently available gene networks. We show how these empirical estimates of average connectedness are used to validate candidate gene pairs. Validation of interacting genes by comparing their connectedness with the average connectedness in the gene network will provide support for said interactions by utilising the growing amount of gene network information available.

Vitamin K food composition data have historically been limited to plant-based phylloquinone (vitamin K1). The purpose of this study was to expand analysis of vitamin K to animal products and to measure phylloquinone and 10 forms of menaquinones (vitamin K2) in processed and fresh-cut pork products. Nationally representative samples of processed pork products (n = 28) were obtained through USDA's National Food and Nutrition Analysis Program, and fresh pork (six cuts; n = 5 per cut) and bacon (n = 4) were purchased from local retail outlets. All samples were analyzed by high-performance liquid chromatography (phylloquinone and menaquinone-4) and atmospheric-pressure chemical ionization-liquid chromatography-mass spectrometry (menaquinone-5 to menaquinone-13). Although low in phylloquinone (processed pork products and fresh pork cuts contained menaquinone-4, menaquinone-10, and menaquinone-11 (range: [35.1 ± 11.0]-[534 ± 89.0] μg of menaquinones per 100 g). The total menaquinone contents of processed pork products were correlated with fat contents (r = 0.935). In summary, processed and fresh-cut pork products are a rich dietary source of menaquinones that are currently unaccounted for in assessment of vitamin K in the food supply.

Microwave Imaging Using CMOS Integrated Circuits with Rotating 4 × 4 Antenna Array on a Breast Phantom

Full Text Available A digital breast cancer detection system using 65 nm technology complementary metal oxide semiconductor (CMOS integrated circuits with rotating 4 × 4 antenna array is presented. Gaussian monocycle pulses are generated by CMOS logic circuits and transmitted by a 4 × 4 matrix antenna array via two CMOS single-pole-eight-throw (SP8T switching matrices. Radar signals are received and converted to digital signals by CMOS equivalent time sampling circuits. By rotating the 4 × 4 antenna array, the reference signal is obtained by averaging the waveforms from various positions to extract the breast phantom target response. A signal alignment algorithm is proposed to compensate the phase shift of the signals caused by the system jitter. After extracting the scattered signal from the target, a bandpass filter is applied to reduce the noise caused by imperfect subtraction between original and the reference signals. The confocal imaging algorithm for rotating antennas is utilized to reconstruct the breast image. A 1 cm3 bacon block as a cancer phantom target in a rubber substrate as a breast fat phantom can be detected with reduced artifacts.

Piecewise linear regression splines with hyperbolic covariates

International Nuclear Information System (INIS)

Cologne, John B.; Sposto, Richard

1992-09-01

Consider the problem of fitting a curve to data that exhibit a multiphase linear response with smooth transitions between phases. We propose substituting hyperbolas as covariates in piecewise linear regression splines to obtain curves that are smoothly joined. The method provides an intuitive and easy way to extend the two-phase linear hyperbolic response model of Griffiths and Miller and Watts and Bacon to accommodate more than two linear segments. The resulting regression spline with hyperbolic covariates may be fit by nonlinear regression methods to estimate the degree of curvature between adjoining linear segments. The added complexity of fitting nonlinear, as opposed to linear, regression models is not great. The extra effort is particularly worthwhile when investigators are unwilling to assume that the slope of the response changes abruptly at the join points. We can also estimate the join points (the values of the abscissas where the linear segments would intersect if extrapolated) if their number and approximate locations may be presumed known. An example using data on changing age at menarche in a cohort of Japanese women illustrates the use of the method for exploratory data analysis. (author)

2017-09-01

In this paper, helium induced hardening effect of tungsten was investigated. 50 keV He2+ ions at fluences vary from 5 × 1015 cm-2 to 5 × 1017 cm-2 were implanted into polycrystalline tungsten at RT to create helium bubble-rich layers near the surface. The microstructure and mechanical properties of the irradiated specimens were studied by TEM and nano-indentor. Helium bubble rich layers are formed in near surface region, and the layers become thicker with the rise of fluences. Helium bubbles in the area of helium concentration peak are found to grow up, while the bubble density is almost unchanged. Obvious hardening effect is induced by helium implantation in tungsten. Micro hardness increases rapidly with the fluence firstly, and more slowly when the fluence is above 5 × 1016 cm-2. The hardening effect of tungsten can be attributed to helium bubbles, which is found to be in agreement with the Bacon-Orowan stress formula. The growing diameter is the major factor rather than helium bubbles density (voids distance) in the process of helium implantation at fluences below 5 × 1017 cm-2.

Biodiversity, biotechnologies and the philosophy of biology.

The thesis of this paper is that in front of the development of biotechnology and of the capacity of techniques of altering the living, there is still a very old philosophy of biology. A rapid historical view is given where the rise and diffusion of the reductionistic paradigm is presented and the connections between this paradigm and biotechnologies are traced. Curiously biotechnologies are still based on the philosophy of F. Bacon. Then the necessity of a new paradigm in biology based on the recent discoveries of complexity is underlined. It is reminded that the main discovery of science of the XX century is that we are living in a small planet of limited resources and frail equilibriums. This discovery asks for a different view of the scientific progress, more linked to the conservation of the Biosphere than to its alteration. Stability is the task for the future interactions of human-kind with nature. For this reason the relationships between stability and diversity are summarised. Finally, as the species is the main step of Biodiversity, a brief discussion of the problems posed by the altering of species barriers is presented.

Mercury and sulphur among the High Medieval alchemists: from Rāzī and Avicenna to Albertus Magnus and pseudo-Roger Bacon.

Newman, William R

2014-11-01

This essay challenges the often expressed view that the principles of metals, namely mercury and sulphur, were generally viewed by alchemists as being of a 'metaphysical' character that made them inaccessible to the tools and operations of the laboratory. By examining a number of Arabo-Latin and Latin alchemical texts in circulation before the end of the thirteenth century, the author presents evidence that most alchemists of the period considered mercury and sulphur to be materials subject to techniques of purification in the same way that naturally occurring salts and minerals could be freed of their impurities or dross. The article also points to the immense influence of Avicenna and Albertus Magnus in formulating the theory that mercury and sulphur were compounds of different materials, containing both fixed and unfixed components. Finally, the author briefly examines the relationship between this materialist approach to the principles and the chymical atomism of early modern authors who were deeply aware of medieval alchemical literature.

A Food Safety Management System (FSMS) implemented in a food processing industry is based on Good Hygienic Practices (GHP), Hazard Analysis Critical Control Point (HACCP) principles and should address both food safety control and assurance activities in order to guarantee food safety. One of the most emerging challenges is to assess the performance of a present FSMS. The objective of this work is to explain the development of a Microbial Assessment Scheme (MAS) as a tool for a systematic analysis of microbial counts in order to assess the current microbial performance of an implemented FSMS. It is assumed that low numbers of microorganisms and small variations in microbial counts indicate an effective FSMS. The MAS is a procedure that defines the identification of critical sampling locations, the selection of microbiological parameters, the assessment of sampling frequency, the selection of sampling method and method of analysis, and finally data processing and interpretation. Based on the MAS assessment, microbial safety level profiles can be derived, indicating which microorganisms and to what extent they contribute to food safety for a specific food processing company. The MAS concept is illustrated with a case study in the pork processing industry, where ready-to-eat meat products are produced (cured, cooked ham and cured, dried bacon).

The Renaissance Kidney-Nephrology in and about the Sixteenth Century.

The endeavor to understand the workings of the human body is as old as civilization; but it is in the intellectual movement of the Renaissance that its actual scientific study began in earnest and has not ceased growing since then. It was in the 16th century that the study of organs was launched and with it that of the kidney, which was then conceived as an accessory organ to clear the excess water ingested with food. The study of the structural basis of kidney function was launched by Bartolomeo Eustachio (1514-1574); the elements of its physiology and pathology were promulgated by Jean Fernel (1497-1558), and that of the chemical study of urine and of the principal cause of kidney disease then, calculi, instigated by Joan Baptista Van Helmont (1577-1644). The methodological approaches of these and their contemporary investigators, which were crystallized and formulated by Francis Bacon (1561-1626), opened the gates of the Scientific Revolution that followed in the 17th century, beginning with that of describing the circulation in 1628 by William Harvey (1564-1657) that would finally free the kidney from the shackles imposed on it as a mere accessory organ to the liver in Galen's physiology. © 2012 Wiley Periodicals, Inc.

Chapter 24: the coming of molecular biology and its impact on clinical neurology.

Smith, Christopher U M

2010-01-01

Although the chemical study of the nervous system dates back well into the 19th century, molecular biology and especially molecular neurobiology only began to be established in the second half of the 20th century. This chapter reviews their impact on clinical neuroscience during the 50 years since Watson and Crick published their seminal paper. After a short review of the part played by F.O. Schmitt in establishing molecular neuroscience the chapter outlines work that led to a detailed understanding of the biochemical structure and function of nerve cell membranes and their embedded channel proteins, receptors, and other molecules. The chapter then turns to the numerous pathologies that result from disorders of these elements: the various channel and gap-junction pathologies. The chapter continues with a discussion of some of the diseases caused by defective DNA, especially the trinucleotide repeat expansion diseases (TREDs) and ends with a short account of the development of molecular approaches to prion diseases, myasthenia gravis, and the neurodegenerative diseases of old age. Francis Bacon said long ago that "knowledge is power." The hope is that increasing molecular knowledge will help cure some of the human suffering seen in the neurological ward and clinic.

«The Multiplicity of Agreeable Consciousness»

Full Text Available Samuel Johnson’s life was troubled by diverse physical diseases and – one year before his death – he experienced a stroke. Moreover, he suffered from recurring fits of depression. But Johnson was also merry, loved witty conversations, good food and his nightly tours through London pubs. Johnson maintained that pleasure and pain were closely connected with each other. In both his dialogues with James Boswell and in his comprehensive literary works, Johnson reveals a philosophy of happiness characterized by a radical skepticism reminiscent of Michel de Montaigne’s Pyrrhonism. Influenced by Richard Burton, Thomas Browne and Francis Bacon, Johnson developed his specific doctrine of eudaemonic idols: as an idiosyncratic representative of Enlightenment philosophy he examined and questioned traditional clichès of happiness such as Stoicism, natural philosophy, learning, and marriage. Though not completely denying the possibility of earthly happiness, which he defined as the «multiplicity of agreeable consciousness», he was convinced that all earthly pleasures were doomed to fade away. As «a gloomy gazer on a world» to which he had «little relation», Johnson gave up any hope of attaining happiness on earth and exclusively trusted in felicity beyond the grave.

Ford, Bacon and Davis Utah Inc. has performed an engineering assessment of the problems resulting from the existence of radioactive uranium mill tailings at Durango, Colorado. The Phase II, Title I services include the preparation of topographic maps, the performance of core drillings and radiometric measurements sufficient to determine areas and volumes of tailings and other radium-contaminated materials, the evaluation of resulting radiation exposures of individuals and nearby populations, the investigation of site hydrology and meteorology and the evaluation and costing of alternative corrective actions. Radon gas release from the 1.555 million tons of tailings at the Durango site constitutes the most significant environmental impact, although windblown tailings and external gamma radiation are also factors. The eight alternative actions presented range from vegetative stabilization (Option I), to contouring and stabilizing in-place with varying depths of cover material (Options II and III), to removal to an isolated long-term disposal site (Options V to VIII). All options include remedial action costs for offsite locations where tailings have been placed. Costs estimated for the eight options range from $4,340,000 to $13,590,000. Reprocessing the tailings for uranium is sufficiently economically attractive to justify reprocessing in conjunction with each of the options

Radon gas release from the tailings on the site constitutes the most significant environmental impact, although windblown tailings and external gamma radiation are also factors. The sparse population and relatively low radiation levels yield minimal immediate environmental impact; hence, the two alternative actions presented are directed towards restricting access to the site (Options I and II), and returning the windblown tailings to the pile and stabilizing the pile with 2 ft of cover material (Option II). Both options include remedial action costs for offsite locations where tailings have been placed. Cost estimates for the two options are $585,000 and $1,165,000.

Food irradiation and sterilization

Science.gov (United States)

Josephson, Edward S.

Radiation sterilization of food (radappertization) requires exposing food in sealed containers to ionizing radiation at absorbed doses high enough (25-70 kGy) to kill all organisms of food spoilage and public health significance. Radappertization is analogous to thermal canning is achieving shelf stability (long term storage without refrigeration). Except for dry products in which autolysis is negligible, the radappertization process also requires that the food be heated to an internal temperature of 70-80°C (bacon to 53°C) to inactivate autolytic enzymes which catalyze spoilage during storage without refrigeration. To minimize the occurence of irradiation induced off-flavors and odors, undesirable color changes, and textural and nutritional losses from exposure to the high doses required for radappertization, the foods are vacuum sealed and irradiated frozen (-40°C to -20°C). Radappertozed foods have the characteristic of fresh foods prepared for eating. Radappertization can substitute in whole or in part for some chemical food additives such as ethylene oxide and nitrites which are either toxic, carcinogenic, mutagenic, or teratogenic. After 27 years of testing for "wholesomeness" (safety for consumption) of radappertized foods, no confirmed evidence has been obtained of any adverse effecys of radappertization on the "wholesomeness" characteristics of these foods.

[Euthanasia in history and the present - in the spectrum between euthanasia and terminal care].

Science.gov (United States)

von Engelhardt, Dietrich

2010-01-01

Euthanasia signifies in antiquity an easy and happy death and not at all an active termination of life, which was forbidden in the Hippocratic oath, but justified by philosophers. In the Christian middle ages active euthanasia and abortion are explicitly refused. At the beginnings of modern times MORE (1516) and BACON (1623) plead for euthanasia and differentiate for the first time between "euthanasia interior" as a mental preparation and "euthanasia exterior" as a physical and direct termination of life. Around 1900 a change takes place--in medicine as well as in the humanities and arts. The lawyer Karl BINDING and the psychiatrist Alfred HOCHE (1920) support active euthanasia in the case of mental deficiency; similar views are taken by the population. Under the "Third Reich" euthanasia unlawfully is carried out as termination of life without or even against consent. Today oaths, declarations and laws are intended to prevent such a "medicine without humanity" (MITSCHERLICH and MIELKE 1947). Active voluntary euthanasia is under certain conditions allowed by the legislation in some countries (Netherlands, Belgium, Luxembourg). Essential seem the consideration of different types of euthanasia and above all a psychical-mental assistance in the process of dying. The height of culture is measured by dealing with death and dying.

Seaweeds for umami flavour in the New Nordic Cuisine

Directory of Open Access Journals (Sweden)

Mouritsen Ole G

2012-03-01

Full Text Available Abstract Use of the term 'umami' for the fifth basic taste and for describing the sensation of deliciousness is finding its way into Western cuisine. The unique molecular mechanism behind umami sensation is now partly understood as an allosteric action of glutamate and certain 5'-ribonucleotides on the umami receptors. Chefs have started using this understanding to create dishes with delicious taste by adding old and new ingredients that enhance umami. In this paper, we take as our starting point the traditional Japanese soup broth dashi as the 'mother' of umami and demonstrate how dashi can be prepared from local, Nordic seaweeds, in particular the large brown seaweed sugar kelp (Saccharina latissima and the red seaweed dulse (Palmaria palmata, possibly combined with bacon, chicken meat or dried mushrooms to provide synergy in the umami taste. Optimal conditions are determined for dashi extraction from these seaweeds, and the corresponding glutamate, aspartate and alaninate contents are determined quantitatively and compared with Japanese dashi extracted from the brown seaweed konbu (Saccharina japonica. Dulse and dashi from dulse are proposed as promising novel ingredients in the New Nordic Cuisine to infuse a range of different dishes with umami taste, such as ice cream, fresh cheese and bread.

2012-03-01

Heterocyclic amines (HCAs), potent mutagens and a risk factor for human cancers, are produced in meats cooked at high temperature. The aim of this study was to determine the HCA content in cooked meat products (beef, chicken, pork, fish) prepared by various cooking methods (pan frying, oven broiling, and oven baking at 170 to 230°C) that are preferred by U.S. meat consumers. The primary HCAs in these samples were PhIP (2-amino-1-methyl-6-phenylimidazo [4,5-b]pyridine) (1.49-10.89ng/g), MeIQx (2-amino-3,8-dimethylimidazo [4,5-f]quinoxaline) (not detected-4.0ng/g), and DiMeIQx (2-amino-3,4,8-trimethyl-imidazo [4,5-f]quinoxaline) (not detected-3.57ng/g). Type and content of HCAs in cooked meat samples were highly dependent on cooking conditions. The total HCA content in well-done meat was 3.5 times higher than that of medium-rare meat. Fried pork (13.91ng/g) had higher levels of total HCAs than fried beef (8.92ng/g) and fried chicken (7.00ng/g). Among the samples, fried bacon contained the highest total HCA content (17.59ng/g).

2015-01-01

Full Text Available The indentation behaviour of aluminium foams at low velocity (10 m/s ∼ 30 m/s was investigated both in experiments and numerical simulation in this paper. A flat-ended indenter was used and the force-displacement history was recorded. The Split Hopkinson Pressure bar was used to obtain the indentation velocity and forces in the dynamic experiments. Because of the low strength of the aluminium foam, PMMA bar was used, and the experimental data were corrected using Bacon's method. The energy absorption characteristics varying with impact velocity were then obtained. It was found that the energy absorption ability of aluminium foam gradually increases in the quasi-static regime and shows a significant increase at ∼10 m/s velocity. Numerical simulation was also conducted to investigate this process. A 3D Voronoi model was used and models with different relative densities were investigated as well as those with different failure strain. The indentation energy increases with both the relative density and failure strain. The analysis of the FE model implies that the significant change in energy absorption ability of aluminium foam in indentation at ∼10 m/s velocity may be caused by plastic wave effect.

Full Text Available Kaftas with V-shaped filleting chips of the Nile tilapia (Oreochromis niloticus were developed and the effects of the smoking technique on the characteristics of chemical composition, microbiological, sensory and benzo(apyrene were investigated. The filleting chips were ground and filleting included condiments and bacon. Kaftas were molded, frozen and distributed in a completely randomized design with three treatments (T 1 = baked in a grid; T 2 = smoked by friction and T 3 = smoked by liquid smoke with 10 replications. The kaftas subjected to hot smoke had lower moisture content (13.97%, whereas the no-smoking kaftas had the highest content (20.49%. Kaftas with liquid smoke had high crude protein content (48.06% and ash (9.49%, whereas the ash content was different only from no-smoking kaftas (8.79%. There was no significant difference in sensory parameters, except for flavor; smoked kaftas with liquid smoke were more accepted by the judges and the worst kaftas were no-smoked kaftas. Microbiological analysis showed that kaftas developed were appropriate to feed human beings within the required standards. Chips filleting is an alternative for the development of kaftas and those subjected to liquid smoke were considered the best.

Full Text Available The main authors in the area of Human Resource Management (HRM, including Legge (2006 and Wilkinson,Bacon, Redman and Snell (2010, agree that people have an important and strategic role in organizations. Since HRM policies need to contribute to greater well-being and strengthen the confidence of employees in organizations (Mariotti & Souza, 2009; Nishii, Lepak, & Schneider, 2008; Turner, Huemann, & Keegan, 2008, this study aimed to assess the relationship between these variables, as perceived by 141 employees in a multinational company in the field of information technology. Multiple linear regression analysis, structural equation modeling and maximum likelihood method were conducted to test the proposed models of relationships between the variables cited above. Thus, it was possible to identify and confirm the influence HRM policies have on both confidence in the organization and employee well-being at work, as well as the influence of confidence on well-being at work. This research contributes to the advancement of studies in the areas of Human Resources Management and Organizational Behavior by analyzing a previously unexplored relationship between a set of variables and also served as a diagnostic for the studied organization, assisting company managers in their decision-making in order to improve employee well-being.

This report describes the control decisions for flammable gas hazards in waste transfer systems (i.e., waste transfer piping and waste transfer-associated structures) made at control decision meetings on November 30, 1999a and April 19, 2000, and their basis. These control decisions, and the analyses that support them, will be documented in an amendment to the Final Safety Analysis Report (FSAR) (CHG 2000a) and Technical Safety Requirements (TSR) (CHG 2000b) to close the Flammable Gas Unreviewed Safety Question (USQ) (Bacon 1996 and Wagoner 1996). Following the Contractor Tier I review of the FSAR and TSR amendment, it will be submitted to the US. Department of Energy (DOE), Office of River Protection (ORP) for review and approval. The control decision meeting on November 30, 1999 to address flammable gas hazards in waste transfer systems followed the control decision process and the criteria for control decisions described in Section 3.3.1.5 of the FSAR. The control decision meeting agenda, attendance list, and introductory and background presentations are included in Attachments 1 through 4. The control decision discussions on existing and other possible controls for flammable gas hazards in waste transfer systems and the basis for selecting or not selecting specific controls are summarized in this report

2012-01-01

Since the revision of the 10CFR50.46 in 1988, which allowed BE (Best-Estimate) method in analyzing the safety performance of a nuclear power plant, safety analysis methodologies have been changed continuously from conservative EM (Evaluation Model) approaches to BE ones. In this context, LSC (Long-Term core Cooling) methodologies have been reviewed by the regulatory bodies of USA and Korea. Some non-conservatism and improperness of the old methodology have been identified, and as a result, USNRC suspended the approval of CENPD-254-P-A which is the old LSC methodology for CE-designed NPPs. Regulatory bodies requested to remove the non-conservatisms and to reflect system transient behaviors in all the LSC methodologies used. In the present study, a new LSC methodology using RELAP5 is developed. RELAP5 and a newly developed code, BACON (Boric Acid Concentration Of Nuclear power plant) are used to calculate the transient behavior of the system and the boric acid concentration, respectively. Full range of break spectrum is considered and the applicability is confirmed through plant demonstration calculations. The result shows a good comparison with the old-fashioned ones, therefore, the methodology could be applied with no significant changes of current LSC plans

PIGS BREEDING FOR THE PRODUCTION OF TRADITIONAL MEAT PRODUCTS

Directory of Open Access Journals (Sweden)

Đuro Senčić

2014-06-01

Full Text Available The fertile Slavonia is known for production of several types of cured meats: kulen, kulen sis, sausage, ham and bacon, and other pork products (“krvavica” - blood sausage, “švargl” - a type of brawn where chopped parts of head are stuffed inside the pig’s stomach, “čvarci” - a variant of pork crisps, fat. These products require “mature pigs” of adequate slaughter quality. Production of pigs intended for traditional meat products may take place in different production systems (open, closed, semi-open, “organic”. Each of these systems provides a specific quality of pigs for slaughter, reflecting on the quality of the final product. Production systems can have a significant impact on growth performance and carcass and meat quality of pigs. This effect arises from the interaction between housing conditions, the amount and composition of food and used pig genotype. The choice of a production system depends on local production conditions, pig genotype, consumer demand (market for a given product quality, and other factors. Due to their quality, the traditional Slavonian meat products can become a recognizable Croatian brand in both domestic and international markets. Production of standard quality products requires standard quality of pigs. Therefore this book is focused on such pigs production.

Engineering assessment of inactive uranium mill tailings, Belfield Site, Belfield, North Dakota

International Nuclear Information System (INIS)

1981-11-01

Ford, Bacon and Davis Utah Inc. has evaluated the Belfield site in order to assess the problems resulting from the existence of radiactive ash at Belfield, South Dakota. This engineering assessment has included drilling of boreholes and radiometric measurements sufficient to determine areas and volumes of ash and radiation exposures of individuals and nearby populations, the investigations of site hydrology and meteorology, and the evaluation and costing of alternative corrective actons. Radon gas released from the 55,600 tons of ash and contaminated material at the Belfield site constitutes a significant environmental impact, although external gamma radiation also is a factor. The four alternative actions presented in this engineering assessment range from millsite and off-site decontamination with the addition of 3 m of stabilization cover material, to removal of the ash and contaminated materials to remote disposal sites, and decontamination of the Belfield site. Cost estimates for the four options range from about $1,500,000 for stabilization in-place, to about $2,500,000 for disposal at a distance of about 17 mi from the Belfield site. Reprocessing the ash for uranium recovery is not feasible because of the extremely small amount of material available at the site and because of its low U 3 O 8 content

'For Beauty is nothing but the barely endurable onset of Terror': Outline of a general psychoanalytic aesthetics.

Science.gov (United States)

Leikert, Sebastian

2017-06-01

Even close to 80 years after Freud's words that psychoanalysis "has scarcely anything to say about beauty" (Freud, Civilization and its Discontents, SE 21, p. 82) the question of a specific psychoanalytic aesthetic is still faced with a deficit in theory. Since aesthetics is related to Aisthesis, the Greek word for 'perception', a psychoanalytic aesthetic can solely emerge from a psychoanalysis of perceptive structures. The term 'kinaesthetic semantic' is introduced in order to exemplify via music how perceptive experiences must be structured for them to be experienced as beautiful. The basic mechanisms - repetition of form (rhythm, unification) and seduction (deviation, surprise) - are defined. With the help of these mechanisms an intensive contact between perceiving object and kinetic subject, the physical self, is established. The intensive relatedness is a requirement for the creative process in art and also for psychic growth on the subject's level. The described basic mechanisms of the aesthetic process in music can also be encountered in painting and poetry. By the means of a self-portrait by Bacon it will be examined how, in art, terror and traumatization are represented via targeted disorganization of beauty endowing mechanisms, hence finding an enabling form of confrontation and integration of fended contents.

"Hold up..do pigs eat bacon?!" An investigation of science instruction for urban Black youth and the need for a culturally considerate response

Science.gov (United States)

Ridgeway, Monica Lynn

As a critical race ethnography, this dissertation attempts to foreground the richness of Black urban youth culture during and around science classroom instruction. Ironically, during an era of much diversity rhetoric in the United States, the culture of urban Black youth is rarely reflected in mainstream public school culture. I attempt to explicate such a worldview compassionately and authentically for both insiders and outsiders of the lived experiences of Black America. Education in the United States can be damning for Black youth who do not fit the mainstream mold, and several authors have provided detailed critique of mechanisms that shape, direct, and marginalize outliers to the successful academic cultural model. The U.S. through this lens is experiencing an opportunity gap, not an achievement gap--one which equitable educational experience can best be viewed through the richness of critical ethnographic methods. This methodical approach allowed me as a researcher to listen to marginalized voices and to incorporate lived interactions with youth, their parents, and community stakeholders all committed to provide support for the today's youth. As a Black female science educator, I explore the evidence for reform impact as I examine in school experiences and science teaching of culturally relevant pedagogies for urban, working-class and poor families of color in grades six-eight who participated in a Western New York academic enrichment program. Findings suggest that skepticism of reform efforts and new pedagogical approaches existed for all stakeholders aforementioned, but that students were the most amenable and responsive to alternative educational approaches. Specific recommendations for engaging students in inquiry processes are given for teachers, institutions, parents and students on the basis of videotaped lessons, interviews, and instructional artifacts. Implications include the recommendations that educators working with youth of color need to be prepared to discuss the ethnic and racial identities of students and jointly construct a sense of activism and empowerment in the face of existing systemic oppression that can and should be eliminated if we are to reach the national goal (AAAS, 1986) of "Science for All Americans," professed as many as three decades ago.

Engineering assessment of inactive uranium mill tailings: Monument Valley Site, Monument Valley, Arizona

Energy Technology Data Exchange (ETDEWEB)

1981-10-01

Ford, Bacon and Davis Utah Inc. has reevalated the Monument Valley site in order to revise the March 1977 engineering assessment of the problems resulting from the existence of radioactive uranium mill tailings at Monument Valley, Arizona. This engineering assessment has included the preparation of topographic maps, the performance of core drillings and radiometric measurements sufficient to determine areas and volumes of tailings and radiation exposure of individuals and nearby populations, the investigations of site hydrology and meteorology, and the evaluation and costing of alternative corrective actions. Radon gas released from the 1.1 million tons of tailings at the Monument Valley site constitutes the most significant environmental impact, although windblown tailings and external gamma radiation also are factors. The four alternative actions presented in this engineering assessment range from millsite decontamination with the addition of 3 m of stabilization cover material (Option I), to removal of the tailings to remote disposal sites and decontamination of the tailings site (Options II through IV). Cost estimates for the four options range from about $6,600,000 for stabilization in-place, to about $15,900,000 for disposal at a distance of about 15 mi. Three principal alternatives for reprocessing the Monument Valley tailings were examined: heap leaching; Treatment at an existing mill; and reprocessing at a new conventional mill constructed for tailings reprocessing. The cost of the uranium recovery is economically unattractive.

Hydrogen-bond memory and water-skin supersolidity resolving the Mpemba paradox.

The Mpemba paradox, that is, hotter water freezes faster than colder water, has baffled thinkers like Francis Bacon, René Descartes, and Aristotle since B.C. 350. However, a commonly accepted understanding or theoretical reproduction of this effect remains challenging. Numerical reproduction of observations, shown herewith, confirms that water skin supersolidity [Zhang et al., Phys. Chem. Chem. Phys., DOI: ] enhances the local thermal diffusivity favoring heat flowing outwardly in the liquid path. Analysis of experimental database reveals that the hydrogen bond (O:H-O) possesses memory to emit energy at a rate depending on its initial storage. Unlike other usual materials that lengthen and soften all bonds when they absorb thermal energy, water performs abnormally under heating to lengthen the O:H nonbond and shorten the H-O covalent bond through inter-oxygen Coulomb coupling [Sun et al., J. Phys. Chem. Lett., 2013, 4, 3238]. Cooling does the opposite to release energy, like releasing a coupled pair of bungees, at a rate of history dependence. Being sensitive to the source volume, skin radiation, and the drain temperature, the Mpemba effect proceeds only in the strictly non-adiabatic 'source-path-drain' cycling system for the heat "emission-conduction-dissipation" dynamics with a relaxation time that drops exponentially with the rise of the initial temperature of the liquid source.

Summary of the engineering assessment of inactive uranium mill tailings, Durango Site, Durango, Colorado

Ford, Bacon and Davis Utah Inc. has reevaluated the Durango site in order to revise the November 1977 engineering assessment of the problems resulting from the existence of radioactive uranium mill tailings at Durango, Colorado. This engineering assessment has included the preparation of topographic measurements sufficient to determine areas and volumes of tailings and radiation exposures of individuals and nearby populations, the investigations of site hydrology and meteorology, and the evaluation and costing of alternative corrective actions. Radon gas released from the nearly 1.6 million tons of tailings at the Durango site constitutes the most significant environmental impact, although windblown tailings and external gamma radiation also are factors. The four alternative actions presented in this engineering assessment range from millsite and off-site decontamination with the addition of 3 m of stabilization cover material (Option I), to removal of the tailings to remote disposal sites and decontamination of the tailings site (Options II through IV). Cost estimates for the seven options range from about $10,700,000 for stabilization in-place, to about $21,800,000 for disposal at a distance of about 10 mi. Three principal alternatives for the reprocessing of the Durango tailings were examined: (a) heap leaching; (b) treatment at an existing mill; and (c) reprocessing at a new conventional mill constructed for tailings reprocessing

Nanoscale dislocation shear loops at static equilibrium and finite temperature

Dang, Khanh; Capolungo, Laurent; Spearot, Douglas E.

2017-12-01

Atomistic simulations are used to determine the resolved shear stress necessary for equilibrium and the resulting geometry of nanoscale dislocation shear loops in Al. Dislocation loops with different sizes and shapes are created via superposition of elemental triangular dislocation displacement fields in the presence of an externally imposed shear stress. First, a bisection algorithm is developed to determine systematically the resolved shear stress necessary for equilibrium at 0 K. This approach allows for the identification of dislocation core structure and a correlation between dislocation loop size, shape and the computed shear stress for equilibrium. It is found, in agreement with predictions made by Scattergood and Bacon, that the equilibrium shape of a dislocation loop becomes more circular with increasing loop size. Second, the bisection algorithm is extended to study the influence of temperature on the resolved shear stress necessary for stability. An approach is presented to compute the effective lattice friction stress, including temperature dependence, for dislocation loops in Al. The temperature dependence of the effective lattice friction stress can be reliably computed for dislocation loops larger than 16.2 nm. However, for dislocation loops smaller than this threshold, the effective lattice friction stress shows a dislocation loop size dependence caused by significant overlap of the stress fields on the interior of the dislocation loops. Combined, static and finite temperature atomistic simulations provide essential data to parameterize discrete dislocation dynamics simulations.

Engineering assessment of inactive uranium mill tailings, Mexican Hat site, Mexican Hat, Utah. A summary of the Phase II, Title I

International Nuclear Information System (INIS)

1977-01-01

Ford, Bacon and Davis Utah Inc. has performed an engineering assessment of the problems resulting from the existence of radioactive uranium mill tailings at the Mexican Hat millsite in Utah. The Phase II, Title I services include the preparation of topographic maps, the performance of core drillings and radiometric measurements sufficient to determine areas and volumes of tailings and other radium-contaminated materials, the evaluation of resulting radiation exposures of individuals residing nearby, the investigation of site hydrology and meteorology, and the evaluation and costing of alternative corrective actions. Radon gas release from the 2,200,000 tons of tailings on the site constitutes the most significant environmental impact. The six alternative actions presented are directed towards restricting access to the site (Option I), returning the windblown tailings to the piles and stabilizing the piles with cover material (Options II, III, and IV), and consolidating the two piles into one pile and stabilizing it with cover material (Options V and VI). Fencing around the site or the tailings and the decontamination of mill buildings is included in all options. Options II and V provide 2 ft of cover material on the tailings, Options III, IV, and VI provide 4 ft, 13 ft, and 10 ft of cover, respectively. Costs of the options range from $370,000 to $4,390,000. Reprocessing the tailings for uranium is not feasible at present

Assessment of the radiological impact of the inactive uranium-mill tailings at Monument Valley, Arizona

Haywood, F.F.; Goldsmith, W.A.; Hubbard, H.M. Jr.; Fox, W.F.; Shinpaugh, W.H.

1979-12-01

Results of a radiological survey that was conducted at the inactive uranium-mill site at Monument Valley, Arizona, in March 1976, in cooperation with a team from Ford, Bacon and Davis Utah Inc., are presented. Consideration of these data and of previously published information on radiological conditions at the site lead to the conclusion that potential health effects from exposure to radionuclides in the mill tailings are relatively small. The occupants of three residences within 0.8 km (0.5 mile) of the tailings constitute the principal population at risk, but direct gamma-exposure rate measurements near the two residences closest to the tailings and calculations of radon dispersion indicate that the tailings do not raise either pathway of radiation exposure significantly above the background level. Data are not available to evaluate fully other possible exposure pathways, but the available information indicates that it is unlikely that doses through these pathways will add significantly to the total population dose. The low estimates of potential health effects from exposure to direct radiation and to exposure to radionuclides in the Monument Valley tailings piles are ascribed to the low 226 Ra inventory, to almost complete absence of small particles that are readily moved by wind and water, and to a small population in the vicinity of the tailings

Indoor sources can greatly contribute to personal exposure to particulate matter less than 2.5 μm in diameter (PM2.5). To accurately assess PM2.5 mass emission factors and concentrations, real-time particle monitors must be calibrated for individual sources. Sixty-six experiments were conducted with a common, real-time laser photometer (TSI SidePak™ Model AM510 Personal Aerosol Monitor) and a filter-based PM2.5 gravimetric sampler to quantify the monitor calibration factors (CFs), and to estimate emission factors for common indoor sources including cigarettes, incense, cooking, candles, and fireplaces. Calibration factors for these indoor sources were all significantly less than the factory-set CF of 1.0, ranging from 0.32 (cigarette smoke) to 0.70 (hamburger). Stick incense had a CF of 0.35, while fireplace emissions ranged from 0.44-0.47. Cooking source CFs ranged from 0.41 (fried bacon) to 0.65-0.70 (fried pork chops, salmon, and hamburger). The CFs of combined sources (e.g., cooking and cigarette emissions mixed) were linear combinations of the CFs of the component sources. The highest PM2.5 emission factors per time period were from burned foods and fireplaces (15-16 mg min(-1)), and the lowest from cooking foods such as pizza and ground beef (0.1-0.2 mg min(-1)).

In a population-based case-control study of 416 incident gliomas in adults carried out in Melbourne, Australia, between 1987 and 1991, 409 age-sex-matched case-control pairs (243 male and 166 female) had adequate data available to examine associations between the dietary intake of N-nitroso compounds, N-nitroso precursors, other nutrients including N-nitroso inhibitors, and the risk of glioma. Dietary intakes were based on the reported frequency of consumption of 59 food items. Increased odds ratio (OR) were observed in males who consumed high levels of bacon, corned meats, apples, melons and oil. OR less than unity were observed in men consuming cabbage and cola drinks, and in women who consumed wholegrain bread, pasta, corned meat, bananas, cauliflower, brocoli, cola drinks and nuts. Generally, N-nitroso associations were greater in men and micronutrient associations were greater in women. Elevated OR in men, but not women, were associated with the intake of N-nitroso dimethylamine (NDMA), retinol and vitamin E. The intake of nitrate (largely of vegetable origin) was protective in women but not in men. When analyzed using multiple logistic regression, the association with NDMA intake in males was not modified by dietary micronutrient intakes. In females, beta carotene alone, though not directly associated with risk, modified the effect of NDMA. On balance, this study added only limited support to the N-nitroso hypothesis of glial carcinogenesis.

Summary of the engineering assessment of inactive uranium-mill tailings, Bowman Site, Bowman, North Dakota

International Nuclear Information System (INIS)

1981-11-01

Ford, Bacon and Davis Utah Inc. has performed an engineering assessment of the problems resulting from the existence of radioactive residues from the burning of uranium-bearing lignite at Bowman, North Dakota. This engineering assessment has included the preparation of topographic maps, the performance of core drillings and radiometric measurements sufficient to determine areas and volumes of ash residues and radiation exposures of individuals and nearby populations, the investigations of site hydrology and meteorology, and the evaluation and costing of alternative corrective actions. Radon gas released from the 97,000 tons of ash and contaminated materials at the Bowman site constitutes a significant environmental impact, although windblown ash and external gamma radiation also are factors. The four alternative actions presented in this engineering assessment range from millsite decontamination with the addition of 3 m of stabilization cover material (Option I), to removal of the contaminated materials to remote disposal sites and decontamination of the ashing site (Options II through IV). Cost estimates for the four options range from about $1,740,000 for stabilization in-place, to about $3,060,000 for disposal at a distance of about 4 mi. Reprocessing the ash for uranium recovery is not feasible because of the extremely small amount of material available at the site and because of its low U 3 O 8 content

Sedimentary palaeomagnetic data may exhibit some degree of smoothing of the recorded field due to the gradual processes by which the magnetic signal is `locked-in' over time. Here we present a new Bayesian method to construct age-depth models based on palaeomagnetic data, taking into account and correcting for potential lock-in delay. The age-depth model is built on the widely used "Bacon" dating software by Blaauw and Christen (2011, Bayesian Analysis 6, 457-474) and is designed to combine both radiocarbon and palaeomagnetic measurements. To our knowledge, this is the first palaeomagnetic dating method that addresses the potential problems related post-depositional remanent magnetisation acquisition in age-depth modelling. Age-depth models, including site specific lock-in depth and lock-in filter function, produced with this method are shown to be consistent with independent results based on radiocarbon wiggle match dated sediment sections. Besides its primary use as a dating tool, our new method can also be used specifically to identify the most likely lock-in parameters for a specific record. We explore the potential to use these results to construct high-resolution geomagnetic field models based on sedimentary palaeomagnetic data, adjusting for smoothing induced by post-depositional remanent magnetisation acquisition. Potentially, this technique could enable reconstructions of Holocene geomagnetic field with the same amplitude of variability observed in archaeomagnetic field models for the past three millennia.

Full Text Available This work aimed to diagnose the pork meat consumer profile in the city of Aquidauana-MS as the product knowledge and factors related to choice, frequency and amount of meat consumed. The diagnosis was made through semi-structured interviews with consumers directly at sale point. The preference for consumption of beef, chicken and fish, in instead of pork was observed, however, a significant part of the population said it was ready to increase this consumption. The highest frequency of pork meat consumption was once a month. The most consumed were processed bologna, ham, sausage and bacon. Reasons for not consuming pork were not being appreciated and considered a unhealthy food because of the high fat and cholesterol. Ignorance of production method, origin, nutrition, and the many ways to buy and prepare the pork has led to ratify the low local consumption. Consumers of pork meat consider it tasty and tender, however, unhealthy and expensive. Among the factors that could increase consumption stood out promotions, reduction of fat and cholesterol and reduction of price. Are suggested campaigns to increase consumption of pork meat based, especially in low prices, focused on clarifications regarding the nutritional and health qualities, and actions that allow people to find new ways of preparation and consumption.Este trabalho foi conduzido com o objetivo de diagnosticar o perfil do consumidor de carne suína no município de Aquidauana-MS quanto ao conhecimento do produto e os fatores relacionados à escolha, periodicidade e quantidade de carne consumida.

Corn(maize is, of course, native to the New World, and okra (gumbo to the Old. The Dictionary of Jamaican English includes back-to-back entries on oka and okra - the former from a Yoruba word for corn, though in Jamaica it refers to a cassava mush served with an okra sauce (Cassidy & Le Page 1967:328.

Full Text Available O presente artigo coloca em discussão a produção de paisagens como prática que pode envolver diferentes agentes e percepções, não sendo estreitamente vinculado a um único olhar dito objetivo. A partir de tal discussão, mapas e atlas, instrumentos cartográficos por demais usuais, são aqui transformados em conceitos para se pensar a paisagem e sua produção na contemporaneidade levando em conta diferentes recortes epistemológicos, pontos de vista, agentes e sujeitos. Usando o conceito de espasmos advindo da critica do filósofo francês Gilles Deleuze a respeito das pinturas Francis Bacon, tais operadores serão discutidos como espaços autônomos de produção de paisagens a despeito de qualquer imagem exterior existente a priori. Serão usadas duas obras que, por sua vez, apontarão para a definição destes mesmos operadores: o trabalho artístico participativo Alter Bahnhof Vídeo Walk dos artistas Janet Cardiff e George Miller apresentado na DOCUMENTA XIII de Kassel em 2012 e o site interativo We feel Fine. An Exploration of Human Emotion, in Six Movements feito pelos designers Jonathan Harris e Sep Kamvar. E na conclusão, pretende-se discutir o mapa e atlas não como instrumentos de leitura de um real, mas eles mesmos como um real narrativo.

In the middle of the eighteenth century, Carl von Linné, Johann Christoph Gatterer, and Christian Wilhelm Büttner attempted to realize the old idea of deciphering the alphabet of the world, which Francis Bacon had raised as a general postulate of science. This article describes these attempts and their interrelations. Linné used the model of the alphabet to classify plants according to the characters of this fruiting body. Gatterer, one of the leading German historians during the Enlightenment, adopted the botanical method of classification by genus and species to classify the history of scripts. He used the forms of the alphabetic characters to measure the age of manuscripts and to map the process of history as a genealogy of culture. Gatterer collaborated closely with Büttner, the first Göttingen professor of natural history. Büttner constructed a general alphabet of languages which connected the phonetics of language with the historically known alphabets. Early on, diplomatics and ethnography combined the natural order of natural history and the cultural order of the alphabet with the attempt to register development and to document development by the evolution of forms. Based on the shared model of the alphabet and on the common necessity to classify their empirical material, natural history and the description of culture were related attempts in the middle of the eighteenth century to comprehend the alphabetically organized nature and a naturally ordered culture.

Para ser admitido como membro era necessário que o postulante tivesse uma série de características que o distinguisse do cidadão comum, fosse indicado por antigos membros e, por fim, ter sua inclusão submetida a aprovação dos demais associados. Quase cento e cinquenta anos depois, em 1807, foi criada a Geological Society of London, primeira sociedade geológica da história, vista por alguns membros da Royal Society como uma dissidência desnecessária. A princípio, era um clube de treze membros que se propunham a discutir geologia em jantares prazerosos regados a vinho e boa comida. Os critérios de seleção de seus associados eram semelhantes ao da Royal Society e os custos elevados dos jantares dificultavam a participação de aspirantes de baixos recursos financeiros.

Taklimakan Desert, the largest arid landform in the Eurasia, is one of the most important dust sources in the world. Growing evidences shows that millennial-scale abrupt climate changes during the last glacial period in the region. However, records on millennial-scale climate and environmental changes remain poorly understood because dating eolian, lacustrine, and fluvial sediments and establishing the reliable environmental proxies from these records are always challenging. Here, we present 32 AMS 14C dates of bulk sediments, grain size, and Rb/Sr ratio parameters from the oasis sequence and dates of bulk loess and charcoal from the upstream source regions to examine the significance of oasis sediments on millennial-scale environmental changes in the Taklimakan Desert. We found that substantial reversal of radiocarbon dates on total organic carbon (TOC) was controlled by source region organic carbon input. Loess hills, alpine meadow north of the study region provided fluvial deposits along drainage system and deflation in the river valleys further provide eolain materials. We argue that early oasis deposits experienced deflation and re-deposition less severe than the younger oasis deposits. After refining radiocarbon age-depth relationships for an age model by Bacon package, proxy records show substantial abrupt fluctuations in climate and environments during the last glacial period, among which three wet intervals, two dry periods are identified. The wetter and warmer conditions during the Holocene facilitated human to occupy the oasis.

Full Text Available O2 sensors were used to non-destructively monitor O2 levels in commercially packed pre-cooked, convenience modified atmosphere packaging (MAP foods. A substantial level of O2 (>15% was present in packs resulting in a shorter than expected shelf-life, where the primary spoilage mechanism was found to be mould. Various combinations of vacuum (0–0.6 MPa and gas flush (0.02–0.03 MPa (30% CO2/70% N2 settings were assessed as treatments that result in the desired shelf-life (28 days. This was achieved using the combined treatment of vacuum 0.35 MPa and gas flush 0.02 MPa which resulted in a reduction of 6%–9% O2 in all three samples (battered sausages (BS, bacon slices (BA, and meat and potato pies (PP. Reduced O2 levels reflect the microbial quality of products, which has been successfully reduced. Duplicate samples of all product packs were produced using ethanol emitters (EE to see if shelf-life could be further extended. Results showed a further improvement in shelf-life to 35 days. Sensory analysis showed that ethanol flavour and aroma was not perceived by panellists in two of the three products assessed. This study demonstrates how smart packaging technologies, both intelligent and active, can be used to assist in the modification of conventional packaging systems in order to enhance product quality and safety and through the extension of product shelf-life.

Ford, Bacon and Davis Utah Inc. has performed an engineering assessment of the problems resulting from the existence of radioactive uranium mill tailings at Rifle, Colorado. The Phase II - Title I services include the preparation of topographic maps, the performance of core drillings and radiometric measurements sufficient to determine areas and volumes of tailings and other radium-contaminated materials, the evaluation of resulting radiation exposures of individuals and nearby populations, the investigation of site hydrology and meteorology and the evaluation and costing of alternative corrective actions. Radon gas release from the 3.1 million tons of tailings at the two Rifle sites, constitutes the most significant environmental impact. Windblown tailings, external gamma radiation and localized contamination of surface waters are other environmental effects. The 15 alternative remedial action options presented range from millsite decomtamination and off-site remedial action (Options I and IV), to adding various depths of stabilization cover material (Options II, V, VI, and VII), to removal of the tailings to long-term storage sites and decontamination of the present sites (Options III and VIII through XV). Cost estimates for the first 14 options range from $224,000 to $20,300,000. Option XV, estimated at $32,200,000, includes the cost for moving both Rifle tailings piles and the Grand Junction tailings pile to DeBeque for long-term storage and site decontamination after removal of the piles. Reprocessing of the tailings for uranium appears to be economically attractive at present

Full Text Available The Australian Food and Health Dialogue set sodium reduction targets for three food categories (breads, ready-to-eat breakfast cereals and processed meats to be achieved by December, 2013. Sodium levels for 1849 relevant packaged foods on the shelves of Australian supermarkets between 2010 and 2013 were examined. Changes in mean sodium content were assessed by linear mixed models, and the significance of differences in the proportion of products meeting targets was determined using chi-squared or McNemar’s tests. The mean sodium level of bread products fell from 454 to 415 mg/100 g (9% lower, p < 0.001, and the proportion reaching target rose from 42% to 67% (p < 0.005. The mean sodium content of breakfast cereals also fell substantially from 316 to 237 mg/100 g (25% lower, p < 0.001 over the study period. The decline in mean sodium content of bacon/ham/cured meats from 1215 to 1114 mg/100 g (8% lower, p = 0.001 was smaller, but associated with a rise in the proportion meeting the target from 28% to 47%. Declines in mean sodium content did not appreciably differ between companies that did and did not make public commitments to the targets. These data show that the Australian food industry can reduce salt levels of processed foods and provide a strong case for broadening and strengthening of the Food and Health Dialogue (FHD process.

[On the evolution of scientific thought].

The Nominalists of the XIV century, precursors of modern science, thought that science's object was not the general, vague and indeterminate but the particular, which is real and can be known directly. About the middle of the XVII Century the bases of the modern science became established thanks to a revolution fomented essentially by Galileo, Bacon and Descartes. During the XVIII Century, parallel to the development of the great current of English Empiricism, a movement of scientific renewal also arose in continental Europe following the discipline of the Dutch Physicians and of Boerhaave. In the XIX Century, Claude Bernard dominated the scientific medicine but his rigorous determinism impeded him from taking into account the immense and unforeseeable field of the random. Nowadays, we approach natural science and medicine, from particular groups of facts; that is, from the responses of Nature to specific questions, but not from the general laws. Furthermore, in recent epistemology, the concept that experimental data are not pure facts, but rather, facts interpreted within a hermeneutical context has been established. Finally a general tendency to retrieve philosophical questions concerning the understanding of essence and existence can frequently be seen in scientific inquiry. In the light of the evolution of medical thought, it is possible to establish the position of scientific medicine within the movement of ideas dominating in our time.

Ford, Bacon and Davis Utah Inc. has reevaluated the Durango site in order to revise the November 1977 engineering assessment of the problems resulting from the existence of radioactive uranium mill tailings at Durango, Colorado. This engineering assessment has included the preparation of topographic maps, the performance of core drillings and radiometric measurements sufficient to determine areas and volumes of tailings and radiation exposures of individuals and nearby populations, the investigations of site hydrology and meteorology, and the evaluation and costing of alternative corrective actions. Radon gas released from the nearly 1.6 million tons of tailings at the Durango site constitutes the most significant environmental impact, although windblown tailings and external gamma radiation also are factors. The four alternative actions presented in this engineering assessment range from millsite and off-site decontamination with the addition of 3 m of stabilization cover material (Option I), to removal of the tailings to remote disposal sites and decontamination of the tailings site (Options II through IV). Cost estimates for the seven options range from about $10,700,000 for stabilization in-place, to about $21,800,000 for disposal at a distance of about 10 mi. Three principal alternatives for the reprocessing of the Durango tailings were examined: (a) heap leaching; (b) treatment at an existing mill; and (c) reprocessing at a new conventional mill constructed for tailings reprocessing. The cost of the uranium recovered would be about $30/lb U 3 O 8 by either heap leach or conventional plant processes

Persistent environmental contaminants including polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs), non-ortho-polychlorinated biphenyls (PCBs), and polybrominated diphenyl ethers (PBDEs) were analyzed in 65 meat samples collected from supermarkets across the U.S. in 2001. The samples included hamburger, sirloin steaks, pork chops, bacon, and whole chickens from nine different cities. The average PCDD/F/non-ortho-PCB toxic equivalency (TEQ) for all the samples was 0.55 pg/g of lipid (nd (nondetect) = DL (detection limit)/2) with a range from nondetectable to 3.21 pg/g of lipid. For PBDEs, eight congeners were routinely found in the meat samples with an average sum of 1.71 ng/g of lipid (nd = DL/2) and a range from nondetectable to 16.6 ng/g of lipid. While average TEQs were similar to recent values reported in Europe and Asia, the sums of PBDEs in chicken and pork were 3-20 times higher than levels reported in Spain and Japan for these foods. The presence of a few outliers raised the average PBDE sums and indicated that isolated sources of contamination may exist that, if identified, could be removed from the U.S. animal production chain. Using these TEQ and PBDE values and USDA food consumption data, the estimated dietary intake ranges from meat products were 5.3-16.0 pg TEQ and 14.9-44.7 ng of PBDEs/d or 0.1-0.3 pg TEQ and 0.3-0.5 (ng of PBDEs/kg of body mass)/d for an average individual, similar to intakes in other countries.

Law of 22 April 2005 on patients' rights and the end of life in France: setting the boundaries of euthanasia, with regard to current legislation in other European countries.

The term 'euthanasia' is not clearly defined. Euthanasia is evoked in many aspects of terminal care: interruption of curative treatment at the end of life, palliative care or the act of deliberately provoking death through compassion. A law on 'patients' rights and the end of life', promulgated in France on 22 April 2005, led to changes in the French Code of Public Health. In this work, we have first outlined the key provisions of this law and the changes it has brought, then we have compared current legislation on the subject throughout Europe, where a rapid overview of current practice in terminal patient care revealed four different types of legislation: the first authorizes euthanasia (in the sense of provoking death, if this choice is medically justified), the second legalizes 'assisted suicide', the third, which is sometimes referred to as 'passive euthanasia', consists of the non-administration of life-sustaining treatment and, finally, the fourth prohibits euthanasia in any form whatsoever. In the last section, we have attempted to clarify the as yet indistinct notion of 'euthanasia' in order to determine whether the conception of terminal care in the Law of 22 April 2005 was consistent with that put forward by the philosopher Francis Bacon, who claimed that, 'The physician's role is to relieve pain, not only when such relief can lead to healing, but also when it can proffer a calm and trouble-free death, thus putting an end to the suffering and the agony of death' (modern adaptation of the original quote).

Fuel cells 101

Taylor, B.

2003-06-01

A capsule history of fuel cells is given, beginning with the first discovery in 1839 by William Grove, a Welsh judge who, when experimenting with electrolysis discovered that by re-combining the two components of electrolysis (water and oxygen) an electric charge was produced. A century later, in 1958, Francis Thomas Bacon, a British scientist demonstrated the first working fuel cell stack, a technology which was licensed and used in the Apollo spacecraft. In Canada, early research on the development of fuel cells was carried out at the University of Toronto, the Defence Research Establishment and the National Research Council. Most of the early work concentrated on alkaline and phosphoric acid fuel cells. In 1983, Ballard Research began the development of the electrolyte membrane fuel cell, which marked the beginning of Canada becoming a world leader in fuel cell technology development. The paper provides a brief account of how fuel cells work, describes the distinguishing characteristics of the various types of fuel cells (alkaline, phosphoric acid, molten-carbonate, solid oxide, and proton exchange membrane types) and their principal benefits. The emphasis is on proton exchange membrane fuel cells because they are the only fuel cell technology that is appropriate for providing primary propulsion power onboard a vehicle. Since vehicles are by far the greatest consumers of fossil fuels, it follows that proton exchange membrane fuel cells will have the greatest potential impact on both environmental matters and on our reliance on oil as our primary fuel. Various on-going and planned fuel cell demonstration projects are also described. 1 fig.

Summary of the engineering assessment of inactive uranium mill tailings, Naturita site, Naturita, Colorado

International Nuclear Information System (INIS)

1981-07-01

Ford, Bacon and Davis Utah Inc. has reevaluated the Naturita site in order to revise the November 1977 engineering assessment of the problems resulting from the existence of radioactive contamination at the former uranium mill tailings site at Naturita, Colorado. This evaluation has included the preparation of topographic maps, the drilling of boreholes and radiometric measurements sufficient to determine areas and volumes of contaminated materials and radiation exposures of individuals and nearby populations, and the evaluation and costing of alternative remedial actions. Radon gas released from the estimated 344,000 tons of contaminated materials that remain at the Naturita site constitutes the most significant environmental impact, although external gamma radiation also is a factor. The two alternative actions presented in this engineering assessment are stabilization of the site in its present location with the addition of 3 m of stabilization cover material (Option I), and removal of residual radioactive materials to a disposal site and decontamination of the Naturita site (Option II). Cost estimates for the two options are about $7,200,000 for stabilization in-place, and about $8,200,000 for disposal at the Ranchers Exploration and Development Corporation's reprocessing site. Truck haulage would be used to transport the contaminated materials from the Naturita site to the selected disposal site.Ranchers Exploration and Development Corporation removed the tailings from the site, reprocessed them, and disposed of them from 1977 to 1979. There is no noteworthy mineral resource remaining at the former tailings site; therefore, recovery of residual mineral values was not considered in this assessment

This engineering assessment has included the preparation of topographic maps, the performance of core drillings and radiometric measurements sufficient to determine areas and volumes of tailings and radiation exposures of individuals and nearby populations, the investigations of site hydrology and meteorology, and the evaluation and costing of alternative corrective actions. Radon gas released from the 1.1 million tons of tailings at the Monument Valley site constitutes the most significant environmental impact, although windblown tailings and external gamma radiation also are factors. The four alternative actions presented in this engineering assessment range from millsite decontamination with the addition of 3 m of stabilization cover material to removal of the tailings to remote disposal sites and decontamination of the tailings site. Cost estimates for the four options range from about $6,600,000 for stabilization in-place, to about $15,900,000 for disposal at a distance of about 15 mi. Three principal alternatives for reprocessing the Monument Valley tailings were examined: heap leaching, treatment at an existing mill; and reprocessing at a new conventional mill constructed for tailings reprocessing. The cost of the uranium recovered would be more than $500/lb of U 3 O 8 by heap leach or conventional plant processes. The spot market price for uranium was $25/lb early in 1981. Therefore, reprocessing the tailings for uranium recovery is economically unattractive

Full Text Available Abstract Background The study examined correlates of body mass index (BMI in overweight and obese members of a managed care organization seeking treatment for obesity. It assessed intake of specific foods, dietary fat or fiber, and behaviors attempted to control weight. Methods Participants were 508 men and 1293 women who were > 18 years and had a self-reported BMI > 27.0. This paper reports analyses of baseline and 24-month follow-up data from a randomized weight-loss trial. Cross-sectional and prospective relationships between BMI and behaviors were examined with regression analyses controlling for age and education. Results At baseline, hamburger and beef consumption were associated with higher BMI for men; for women, hamburger, fried chicken, hot dog, bacon or sausage, egg, French fry, and overall fat consumption were associated with higher BMI, while eating high fiber cereal, fruit, and overall fiber intake were associated with lower BMI. Virtually all forms of weight control behavior were reported more often in heavier people. Subscribing to exercise magazines, however, was associated with lower BMI. Decreased fat intake and increased fruit/vegetable/fiber intake over the course of the study were associated with reductions in BMI at 24 months. Conclusion The same behaviors that differentiate individuals with different body weight in the general population also differentiate between individuals of different body weights at the high end of the weight distribution. Educational efforts aimed at preventing weight gain and reducing obesity might benefit from focusing on specific foods known to be associated empirically with body weight and weight change over time.

Previous studies have reported that the umami taste of monosodium l-glutamate (MSG) and salty-smelling odors (e.g., soy sauce, bacon, sardines) enhance the perception of saltiness. This study aimed to investigate the neural basis of the enhancement of saltiness in human participants using functional near-infrared spectroscopy (fNIRS). University students who had passed a taste panel test participated in this study. Sodium chloride solutions were presented with or without either 0.10% MSG or the odor of soy sauce. The participants were asked to drink a cup of the stimulus and to evaluate only saltiness intensity in Experiment 1, as well as other sensory qualities in Experiment 2, and temporal brain activity was measured using fNIRS. In Experiment 3, the participants were asked to evaluate saltiness intensity using the time-intensity (TI) method, and the response of the parotid salivary glands was measured using fNIRS. The fNIRS data showed that the added MSG and soy sauce enhanced the hemodynamic response in temporal brain regions, including the frontal operculum, but no effect on the hemodynamic salivary responses was detected. These results indicate that the perceived enhancement of saltiness occurs in the brain region that is involved in central gustatory processing. Furthermore, the results of the sensory evaluations suggest that enhancement of saltiness by the addition of MSG is mainly based on fusion of the salty-like property of MSG and saltiness of NaCl, whereas enhancement by the addition of soy sauce odor is mainly based on modulation of the temporal dynamics of saltiness perception.

CSciBox is an integrated software system for the construction and evaluation of age models of paleo-environmental archives. It incorporates a number of data-processing and visualization facilities, ranging from simple interpolation to reservoir-age correction and 14C calibration via the Calib algorithm, as well as a number of firn and ice-flow models. It employs modern database technology to store paleoclimate proxy data and analysis results in an easily accessible and searchable form, and offers the user access to those data and computational elements via a modern graphical user interface (GUI). In the case of truly large data or computations, CSciBox is parallelizable across modern multi-core processors, or clusters, or even the cloud. The code is open source and freely available on github, as are one-click installers for various versions of Windows and Mac OSX. The system's architecture allows users to incorporate their own software in the form of computational components that can be built smoothly into CSciBox workflows, taking advantage of CSciBox's GUI, data importing facilities, and plotting capabilities. To date, BACON and StratiCounter have been integrated into CSciBox as embedded components. The user can manipulate and compose all of these tools and facilities as she sees fit. Alternatively, she can employ CSciBox's automated reasoning engine, which uses artificial intelligence techniques to explore the gamut of age models and cross-dating scenarios automatically. The automated reasoning engine captures the knowledge of expert geoscientists, and can output a description of its reasoning.

Engineering assessment of inactive uranium mill tailings, Naturita Site, Naturita, Colorado

International Nuclear Information System (INIS)

1981-07-01

Ford, Bacon and Davis Utah Inc. has reevaluated the Naturita site in order to revise the November 1977 engineering assessment of the problems resulting from the existence of radioactive contamination at the former uranium mill tailings site at Naturita, Colorado. This evaluation has included the preparation of topographic maps, the drilling of boreholes and radiometric measurements sufficient to determine areas and volumes of contaminated materials and radiation exposures of individuals and nearby populations, and the evaluation and costing of alternative remedial actions. Radon gas released from the estimated 344,000 tons of contaminated materials that remain at the Naturita site constitutes the most significant environmental impact, although external gamma radiation also is a factor. The two alternative actions presented in this engineering assessment are stabilization of the site in its present location with the addition of 3 m of stabilization cover material (Option I), and removal of residual radioactive materials to a disposal site and decontamination of the Naturita site (Option II). Cost estimates for the two options are about $7,200,000 for stabilization in-place, and about $8,200,000 for disposal at the Ranchers Exploration and Development Corporations's reprocessing site. Truck haulage would be used to transport the contaminated materials from the Naturita site to the selected disposal site.Ranchers Exploration and Development Corporation removed the tailings from the site, reprocessed them, and disposed of them from 1977 to 1979. There is no noteworthy mineral resource remaining at the former tailings site; therefore, recovery of residual mineral values was not considered in this assessment

I awake, she slept. Sor Juana Ines and Juan Rulfo or the new Latin American poetic condition

Directory of Open Access Journals (Sweden)

Hoover Delgado

2015-12-01

Full Text Available The article examines how Sor Juana Ines de la Cruz and Juan Rulfo, in dialogue with the literary tradition –especially with the work of Dante, Gongorism and the modern tradition– build a Latin American poetic condition. To that end, it studies the long oneiric ascent of Sor Juana, in First Dream; and Susana San Juan’s story, in Pedro Paramo. For the analysis, it goes to the concepts of resistance when suffering and the signals to transcendence provided by Maria Zambrano in her reflections on the essential condition of the human. It explains how Sor Juana and Susana San Juan offer such resistance: Sor Juana through the journey of knowledge, the sovereignty of the body, the exposure of the precariousness of life and the metaphor of the ascent; Susana, through the fall, madness and eroticism. Finally, it interprets in both characters, the appropriation of the signs of transcendence: the revaluation of the moment, of dreams and the creation-destruction of the divine. It concludes by showing how Sor Juana takes the momentum that starts in Europe with Montaigne, Bacon, the Renaissance and the Golden Age and proposes significant transformations that allow speaking of a different poetic condition. And how Rulfo, starting from the American mythic-religious condition, the non-place, the ontological indefiniteness, stops at the image of Purgatory: showing there the luminous consciousness, the unleashed eroticism and the sacralized madness of Susana as a relief, a possibility of leakage and human of redemption of the sentence.

Similar to drugs of abuse, the hedonic value of food is mediated, at least in part, by the mesostriatal dopamine (DA) system. Prolonged intake of either high calorie diets or drugs of abuse both lead to a blunting of the DA system. Most studies have focused on DAergic alterations in the striatum, but little is known about the effects of high calorie diets on ventral tegmental area (VTA) DA neurons. Since high calorie diets produce addictive-like DAergic adaptations, it is possible these diets may increase addiction susceptibility. However, high calorie diets consistently reduce psychostimulant intake and conditioned place preference in rodents. In contrast, high calorie diets can increase or decrease ethanol drinking, but it is not known how a junk food diet (cafeteria diet) affects ethanol drinking. In the current study, we administered a cafeteria diet consisting of bacon, potato chips, cheesecake, cookies, breakfast cereals, marshmallows, and chocolate candies to male Wistar rats for 3-4 weeks, producing an obese phenotype. Prior cafeteria diet feeding reduced homecage ethanol drinking over 2 weeks of testing, and transiently reduced sucrose and chow intake. Importantly, cafeteria diet had no effect on ethanol metabolism rate or blood ethanol concentrations following 2g/kg ethanol administration. In midbrain slices, we showed that cafeteria diet feeding enhances DA D2 receptor (D2R) autoinhibition in VTA DA neurons. These results show that junk food diet-induced obesity reduces ethanol drinking, and suggest that increased D2R autoinhibition in the VTA may contribute to deficits in DAergic signaling and reward hypofunction observed with obesity.

Nutritional counseling for gastroparesis focuses on reduction of meal size, fiber, and fat to control symptoms. The tolerance of gastroparesis patients for particular foods is largely anecdotal. The aim of this study was to identify and characterize foods provoking or alleviating gastroparesis symptoms. Gastroparesis patients completed: (1) Demographic Questionnaire; (2) Patient Assessment of Upper GI Symptoms; (3) Food Toleration and Aversion survey asking patients about experiences when eating certain foods utilizing a scale from -3 (greatly worsening symptoms) to +3 (greatly improving symptoms). Descriptive qualities (acidic, fatty, spicy, roughage-based, bitter, salty, bland, and sweet) were assigned to foods. Forty-five gastroparesis patients participated (39 idiopathic gastroparesis). Foods worsening symptoms included: orange juice, fried chicken, cabbage, oranges, sausage, pizza, peppers, onions, tomato juice, lettuce, coffee, salsa, broccoli, bacon, and roast beef. Saltine crackers, jello, and graham crackers moderately improved symptoms. Twelve additional foods were tolerated by patients (not provoking symptoms): ginger ale, gluten-free foods, tea, sweet potatoes, pretzels, white fish, clear soup, salmon, potatoes, white rice, popsicles, and applesauce. Foods provoking symptoms were generally fatty, acidic, spicy, and roughage-based. The foods shown to be tolerable were generally bland, sweet, salty, and starchy. This study identified specific foods that worsen as well as foods that may help alleviate symptoms of gastroparesis. Foods that provoked symptoms differed in quality from foods that alleviated symptoms or were tolerable. The results of this study illustrate specific examples of foods that aggravate or improve symptoms and provide suggestions for a gastroparesis diet.

Os testes afetivos têm sido um recurso eficiente em vários contextos da análise sensorial. A escolha da escala de mensuração a ser utilizada nestes testes é um aspecto fundamental que vem sendo pouco discutido na literatura nos últimos anos. Este artigo apresenta uma avaliação da precisão das escalas Likert e Stapel frente às usuais Hedônica e Magnitude, utilizadas na mensuração de atributos sensoriais. Dois experimentos foram realizados, um com produto doce (doce de leite em pasta e outro com produto salgado (salgadinho sabor bacon. Aparência, aroma, sabor e textura foram os atributos avaliados por estudantes universitários. Para avaliar a precisão das escalas de mensuração foram adotadas duas abordagens: uma com base em estatísticas de dispersão; e outra examinando dados relativos à opinião dos provadores sobre qual escala eles consideram mais precisa para expressar sua percepção sensorial. Os resultados fornecem evidências de que a influência do atributo e do tipo de produto sobre a precisão das escalas em testes de aceitação não é signifi cante. Mais especifi camente, os resultados sugerem que a escala alternativa Likert apresenta precisão comparável à escala de Magnitude; fato que sugere sua recomendação em testes afetivos com provadores não treinados. A escala Hedônica aparece como a preferida na opinião dos provadores.

Using Shakespeare's Sotto Voce to Determine True Identity From Text

2018-01-01

Little is known of the private life of William Shakespeare, but he is famous for his collection of plays and poems, even though many of the works attributed to him were published anonymously. Determining the identity of Shakespeare has fascinated scholars for 400 years, and four significant figures in English literary history have been suggested as likely alternatives to Shakespeare for some disputed works: Bacon, de Vere, Stanley, and Marlowe. A myriad of computational and statistical tools and techniques have been used to determine the true authorship of his works. Many of these techniques rely on basic statistical correlations, word counts, collocated word groups, or keyword density, but no one method has been decided on. We suggest that an alternative technique that uses word semantics to draw on personality can provide an accurate profile of a person. To test this claim, we analyse the works of Shakespeare, Christopher Marlowe, and Elizabeth Cary. We use Word Accumulation Curves, Hierarchical Clustering overlays, Principal Component Analysis, and Linear Discriminant Analysis techniques in combination with RPAS, a multi-faceted text analysis approach that draws on a writer's personality, or self to identify subtle characteristics within a person's writing style. Here we find that RPAS can separate the known authored works of Shakespeare from Marlowe and Cary. Further, it separates their contested works, works suspected of being written by others. While few authorship identification techniques identify self from the way a person writes, we demonstrate that these stylistic characteristics are as applicable 400 years ago as they are today and have the potential to be used within cyberspace for law enforcement purposes.

Engineering assessment of inactive uranium mill tailings: Maybell Site, Maybell, Colorado. Summary

International Nuclear Information System (INIS)

1981-09-01

Ford, Bacon and Davis Utah Inc. has reevaluated the Maybell site in order to revise the October 1977 engineering assessment of the problems resulting from the existence of radioactive uranium mill tailings at Maybell, Colorado. This engineering assessment has included the preparation of topographic maps, the performance of core drillings and radiometric measurements sufficient to determine areas and volumes of tailings and radiation exposures of individuals and nearby populations, the investigations of site hydrology and meteorology, and the evaluation and costing of alternative corrective actions. Radon gas released from the 2.6 million dry tons of tailings at the Maybell site constitutes the most significant environmental impact, although windblown tailings and external gamma radiation also are factors. The two alternative actions presented in this engineering assessment range from millsite decontamination with the addition of 3 m of stabilization cover material (Option I), to disposal of the tailings in a nearby open pit mine and decontamination of the tailings site (Option II). Cost estimates for the two options are about $11,700,000 for stabilization in-place and about $22,700,000 for disposal within a distance of 2 mi. Three principal alternatives for the reprocessing of the Maybell tailings were examined: (a) heap leaching; (b) treatment at an existing mill; and (c) reprocessing at a new conventional mill constructed for tailings reprocessing. The cost of the uranium recovered would be about $125 and $165/lb of U 3 O 8 by heap leach and conventional plant processes, respectively. The spot market price for uranium was $25/lb early in 1981. Therefore, reprocessing the tailings for uranium recovery is not economically attractive at present

Mechanical Properties and Structures of Pyrolytic Carbon Coating Layer in HTR Coated Particle Fuel

Lee, Young Woo; Kim, Young Min; Kim, Woong Ki; Cho, Moon Sung

2009-01-01

The TRISO(tri-isotropic)-coated fuel particle for a HTR(High Temperature gas-cooled Reactor) has a diameter of about 1 mm, composed of a nuclear fuel kernel and four different outer coating layers, consisting of a buffer PyC (pyrolytic carbon) layer, inner PyC layer, SiC layer, and outer PyC layer with different coating thicknesses following a specific fuel design. While the fuel kernel is a source for a heat generation by a nuclear fission of fissile uranium, each of the four coating layers acts as a different role in view of retaining the generated fission products and the other interactions during an in-reactor service. Among these coating layers, PyC properties are scarcely in agreement among various investigators and the dependency of their changes upon the deposition condition is comparatively large due to their additional anisotropic properties. Although a recent review work has contributed to an establishment of relationship between the material properties and QC measurements, the data on the mechanical properties and structural parameters of PyC coating layers remain still unclearly evaluated. A review work on dimensional changes of PyC by neutron irradiation was one of re-evaluative works recently attempted by the authors. In this work, an attempt was made to analyze and re-evaluate the existing data of the experimental results of the mechanical properties, i.e., Young's modulus and fracture stress, in relation with the coating conditions, density and the BAF (Bacon Anisotropy Factor), an important structural parameter, of PyC coating layers obtained from various experiments performed in the early periods of the HTR coated particle development

Full Text Available Abstract During corn industrial dry milling, a residue rich in dietary fibers is generated. This study aimed to evaluate the effects of micronized corn fiber (MCF as part of a cafeteria diet in the macronutrient metabolism and body weight. Wistar male rats, with initial body weight of 249 ± 14 g (n = 13, received AIN-93M diet (Group 1 or cafeteria diet (Groups 2, 3 and 4, composed of commercial ration, cookies, fried potato sticks, milk chocolate, bacon and chicken liver pâté. Groups 3 and 4 received MCF to replace 100 and 50% of the cellulose from the AIN-93M diet, respectively. After 35 days, blood, tissues and feces were collected. Data were analyzed by ANOVA followed by Tukey test (p < 0.10. The weight gain of the animals increased by 25.9%, 20.8% and 22.0%, when fed cafeteria diet or 100 and 50% of MCF respectively, compared to the control group, although food consumption did not differ between them. Body weight and food efficiency ratio did not differ between the groups fed cafeteria diet with or without MCF. The addition of MCF to the cafeteria diet did not alter the animal lipid profile and glycemia, however, the accumulation of lipids in their livers was similar to the control group. The intake of 100% MCF resulted in higher fecal weight and fecal excretion of lipids, and lower fecal nitrogen, lipid absorption and lipid deposition in the liver than the cafeteria diet. In conclusion, MCF has a potential to improve intestinal transit and lipid excretion, but showed no benefit on blood lipid and glucose levels.

Engineering assessment of inactive uranium mill tailings, Slick Rock sites, Slick Rock, Colorado. A summary of the Phase II, Title I

International Nuclear Information System (INIS)

1977-10-01

Ford, Bacon and Davis Utah Inc. has performed an engineering assessment of the problems resulting from the existence of radioactive uranium mill tailings at the two millsites in Slick Rock, Colorado. The Phase II, Title I services include the preparation of topographic maps, the performance of core drillings and radiometric measurements sufficient to determine areas and volumes of tailings and other radium-contaminated materials, the evaluation of resulting radiation exposures of individuals residing nearby, the investigation of site hydrology and meteorology, and the evaluation and costing of alternative corrective actions. The Union Carbide site has 350,000 tons of tailings and the North Continent site now owned by Union Carbide has 37,000 tons of tailings. Both tailings piles have been stabilized in accordance with regulations of the State of Colorado. Radon gas release from the tailings on the sites constitute the most significant environmental impact, although windblown tailings and external gamma radiation are also factors. The sparse population and relatively low radiation levels yield minimal immediate environmental impact. Hence the three alternative actions presented are directed towards restricting access to the sites (Option I), and returning the windblown tailings to the piles and stabilizing the piles with cover material (Option II), and consolidating the two piles on the UC site and stabilizing with 2 ft of cover (Option III). Fencing around the tailings piles is included in all options. Options II and III provide 2 ft of cover material on the tailings. Costs of the options range from $370,000 to $1,100,000. Reprocessing the tailings for uranium is not economically feasible

Ford, Bacon and Davis Utah Inc. has reevaluated the Falls City site in order to update the December 1977 engineering assessment of the problems resulting from the existence of radioactive uranum mill tailings at Falls City, Texas. This engineering assessment has included the preparation of topographic maps, the performance of core drillings and radiometric measurements sufficient to determine areas and volumes of tailings and radiation exposures of individuals and nearby populations, the investigations of site hydrolgy and meteorology, and the evaluation and costing of alternative corrective actions. Radon gas released from the 2.5 million tons of tailings at the Falls City site constitutes the most significant environmental impact, although windblown tailings and external gamma radiation also are factors. The four alternative actions presented in this engineering assessment range from millsite decontamination with the addition of 3 m of stabilization cover material, to removal of the tailings to remote disposal sites and decontamination of the tailings site. Cost estimates for the four options range from about $21,700,000 for stabilization in place, to about $35,100,000 for disposal at a distance of about 15 mi. Three principal alternatives for the reprocessing of the Falls City tailings were examined: heap leaching; treatment at an existing mill; reprocessing at a new conventional mill constructed for tailings reprocessing. The tailings piles are presently being rewashed for uranium recovery by Solution Engineering, Inc. The cost for further reprocessing would be about $250/lb of U 3 O 8 . The spot market price for uranium was $25/lb early in 1981. Therefore, reprocessing the tailings for uranium recovery does not appear to be economically attractive for the foreseeable future

Thomas Aquinas on the Soul: Old problems, New Solutions. Guiding Premises for a Thomistic Synthesis

Directory of Open Access Journals (Sweden)

Yevgeniy Shilov

2012-12-01

Full Text Available This article examines two main approaches to the doctrine of the soul: that of Plato and that of Aristotle. Each of these approaches had its own development and its own interpretations. Plato and his school was more important during the Middle Ages. Through the neo-platonic philosophers it reached Saint Augustine and became a part of the western cultural and religious heritage until finally it was taken up by member of the Franciscan order - Roger Bacon and Bonaventure. But this paradigm could not solve a host of problems connected with the soul and many of them remained unresolved. The end of the twelfth century brought the growth of the universities and the teaching of Aristotle - a new paradigm - transmitted by the Arabic philosophers which was rediscovered by the West. Two commentators on Aristotle - Averroes and Avicenna -were the most important for the West, especially since Avicenna exerted a great influence on Albert the Great. But both Plato and Aristotle, when taken separately, proved to be quite useless in resolving certain problems. But Thomas Aquinas was able to splice the Gordian knot concealing a solution to the problem of the soul. By combining the psychology of Plato with the metaphysics of Aristotle, Thomas succeeded in creating a new concept of the human person. The author of this article has tried to explain the difficulties which faced Thomas and the way in which Thomas was able to resolve a problem which had troubled philosophy through the ages - the problem of reconciling Plato with Aristotle and finding a way to make their conflicting philosophies agree with each other

Slim by design: serving healthy foods first in buffet lines improves overall meal selection.

Wansink, Brian; Hanks, Andrew S

2013-01-01

Each day, tens of millions of restaurant goers, conference attendees, college students, military personnel, and school children serve themselves at buffets--many being all-you-can-eat buffets. Knowing how the food order at a buffet triggers what a person selects could be useful in guiding diners to make healthier selections. The breakfast food selections of 124 health conference attendees were tallied at two separate seven-item buffet lines (which included cheesy eggs, potatoes, bacon, cinnamon rolls, low-fat granola, low-fat yogurt, and fruit). The food order between the two lines was reversed (least healthy to most healthy, and vise-versa). Participants were randomly assigned to choose their meal from one line or the other, and researchers recorded what participants selected. With buffet foods, the first ones seen are the ones most selected. Over 75% of diners selected the first food they saw, and the first three foods a person encountered in the buffet comprised 66% of all the foods they took. Serving the less healthy foods first led diners to take 31% more total food items (pselection of healthier foods was less common. Three words summarize these results: First foods most. What ends up on a buffet diner's plate is dramatically determined by the presentation order of food. Rearranging food order from healthiest to least healthy can nudge unknowing or even resistant diners toward a healthier meal, helping make them slim by design. Health-conscious diners, can proactively start at the healthier end of the line, and this same basic principle of "first foods most" may be relevant in other contexts - such as when serving or passing food at family dinners.
