  4. Agonistic and reproductive behaviors in males of red hybrid tilapia, Oreochromis niloticus (Linnaeus, 1758 x O. mossambicus (Peters, 1852 (Osteichthyes: Cichlidae

    Directory of Open Access Journals (Sweden)

    APT Medeiros

    Full Text Available The red hybrid tilapia, Oreochromis niloticus (Linnaeus, 1758 x O. mossambicus (Peters, 1852 is a fertile hybrid used in the semi-intensive level of fish culture in the Northeast of Brazil. It is a territorial cichlid and is highly aggressive towards conspecifics during the breeding season. The purpose of this study was to investigate and describe the aggressive behaviour displayed by the males of this hybrid in non-reproductive and reproductive contexts. Behavioural observations revealed that aggression displayed by the reproductive males of red hybrid tilapia included threatening, undulation, parallel, lateral and frontal attacks, chasing, escape and submission. Possession of a territory influenced male aggressiveness, which was more intense in their own territory than that observed in a neutral situation. The males built nests, irrespective of female presence. All the behavioural patterns were in accordance with those previously described for one parental species, the Nile tilapia, O. niloticus.

    1988-01-01

    The fry at the age of 30 and 60 days after hatching were X-irradiated (350 R) and the gonads were studied until the age of 120 days. Previtellogenic oocytes, which were the older generation in the experimental fishes, were more resistant than oogonia and oocytes at various stages of the early meiotic prophase, the number of the latter having been gretly reduced. In some previtellogenic oocytes the nucleus and cytoplasm were damaged, leading to their death. When the 30 day old fishes were irradiated, the nuclei of the previtellogenic oocytes were fragmented. Within 30 days after irradiation of the 60 day old fishes bud-like evaginations of the nuclear envelope appeared in the early vitellogenic oocytes, their function and fate being unclear. The fishes irradiated at the age of 60 days had by 120 days much lesser previtellogenic oocytes than the control fishes; this might decrease the fecundity of fishes in the second spawning

    Oreochromis mossambicus (Peters 1852) (Tilapia) is one of the most consumed fish globally. Tilapia thrives well in environments polluted by urban waste, which invariably contain antibiotic-resistant bacteria and antibiotic resistance genes (ARGs). Thus, Tilapia surviving in such polluted environments may serve as a potential source for dissemination of ARGs. To investigate this, we isolated bacterial strains from gut of Tilapia found in polluted rivers and lakes near Pune, India, and studied the prevalence of resistance genes by molecular methods. A total of 91 bacterial strains were obtained, which include fish pathogens and human pathogens such as Aeromonas hydrophila, Klebsiella pneumoniae, E. coli, Serratia marcescens, Enterobacter spp. and Shigella spp. Overall the prevalence of class 1 integrons, class 2 integrons, extended-spectrum betalactamases (ESBLs) blaCTX-M, blaSHV and aac(6')-Ib-cr gene was 38 percent, 24 percent, 38 percent, 31 percent and 31 percent respectively. Forty-two percent of the Enterobacteriaceae strains carried blaCTX-M gene, which is a common ESBL gene in clinics. The study demonstrates that tilapia found in the polluted waters can serve as reservoirs and an alternative route for human exposure to clinically important ARG-carrying bacteria. The consumption and handling of these fish may pose a potential health risk.

    Full Text Available The fishculture of Tilapia niloiica (Sarotherodon niloticus in freshwater of Ivory Coast. In Ivory Coast, the freshwater fishculture in rural areas is mainly on a small scale. This type of breeding in ponds (2 to 4 ares yields on an average 3 metric tons of fish/ha/year and represents only an activity with self-consumption of products. The yield in intensive pond fishculture Tilapia nilotica is on an average 6 to 7 metric tons/ha/year but yields bigger than 10 metric tons/ha/year are not uncommon. The intensive fishculture in floating cages, requiring a minor investment but a more improved formation than in fischculture, yields on an average about 30 to 40 kg/m3/year. However the effective development of this activity rests on the resolution of problems like the sufficient fry production, the feeding and the commercialization.

    Full Text Available In 2001, the State Library of Victoria in Melbourne built on its holdings of Australian literary manuscripts by acquiring all the papers, drafts and other items associated with Peter Carey’s Booker Prize-winning novel, True History of the Kelly Gang. The centrepiece of this acquisition, and the focus of this article, is Carey’s Apple Mac Classic laptop computer. The argument that is developed in this article is that Carey’s laptop is a technological artefact that operates, especially at the time of its acquisition, as an important talisman in three interrelated senses. First, it was viewed by library staff as a key means of gaining access to the ‘true history’ of Carey’s own creative drive or creative unconscious. Second, its public display alongside other textual objects (mostly books served to reinforce a reconstructed corporate image that endeavoured to reposition the library as a vital contemporary cultural site and key player in Melbourne’s institutional gallery scene. Third, it was a crucial symbolic acquisition insofar as it spoke to certain desires within library management at that time, and which responded to similar moves at major libraries elsewhere around the world, to embrace collection digitisation as the path forward.

    In most teleost fishes, sperm cells are quiescent in the seminal plasma and are activated by either a drop (fresh water fish) or an increase in osmolality (marine fish) when released in the water. It is most interesting to examine how the mechanisms of sperm motility activation can adapt to a broad range of salinities, as applies to some euryhaline species, and particularly to the tilapia Sarotherodon melanotheron heudelotii, which can reproduce at salinities from 0 up to 120 in the wild.

    Full Text Available DNA barcoding has been adopted as a gold standard rapid, precise and unifying identification system for animal species and provides a database of genetic sequences that can be used as a tool for universal species identification. In this study, we employed mitochondrial genes 16S rRNA (16S and cytochrome oxidase subunit I (COI for the identification of some Nigerian freshwater catfish and Tilapia species. Approximately 655 bp were amplified from the 5′ region of the mitochondrial cytochrome C oxidase subunit I (COI gene whereas 570 bp were amplified for the 16S rRNA gene. Nucleotide divergences among sequences were estimated based on Kimura 2-parameter distances and the genetic relationships were assessed by constructing phylogenetic trees using the neighbour-joining (NJ and maximum likelihood (ML methods. Analyses of consensus barcode sequences for each species, and alignment of individual sequences from within a given species revealed highly consistent barcodes (99% similarity on average, which could be compared with deposited sequences in public databases. The nucleotide distance between species belonging to different genera based on COI ranged from 0.17% between Sarotherodon melanotheron and Coptodon zillii to 0.49% between Clarias gariepinus and C. zillii, indicating that S. melanotheron and C. zillii are closely related. Based on the data obtained, the utility of COI gene was confirmed in accurate identification of three fish species from Southwest Nigeria.

    The irradiation effect of 60 Co at the three dose level of 3 mGy, 30 mGy and 300 mGy on the histology of liver of the freshwater fish Oreochromis mossambicus was investigated. The liver of O. mossambicus was dissected out and processed for light microscopy studies. 60 Co exposed O. mossambicus were found to result in several alterations in the histoarchitecture of liver. The alterations included mild congestion of blood vessels, structural alteration, cellular swelling, vacuolation and necrotic liver cells, indicating a definite response to 60 Co irradiation. The results suggest that the liver of O. mossambicus exposed to 60 Co were structurally altered with increasing dose levels. It is to record that alteration in the liver does not affect the physiology, behaviour or lethality of the individuals. Self regulating mechanisms would have influenced the liver to remain sustained. To confirm the same further studies in the direction by increasing dose level is required. - Highlights: ► Fish Oreochromis mossambicus irradiated to the dose of 3 mGy, 30 mGy and 300 mGy. ► Histoarchitecture of liver altered with increasing dose levels of 60 Co. ► Alteration in the liver does not affect the physiology, behaviour or lethality. ► Self regulating mechanisms might have prevented from Lethality. ► HSI index value for exposed group reported ( 60 Co.

    Peter Standley was one of the very early members of CERN staff. He joined CERN nearly 50 years ago and retired 20 years ago. Peter had been reading physics at Oxford University; that made him, in times of the second world war, an obvious candidate to work on the newly invented radar techniques and, as radar officer, he became a member of the Royal Navy. After demobilisation, he was attracted, like many of those working in the radar field, by the construction of particle accelerators, preparing his thesis on the 125 MeV electron synchrotron at the Clarendon Laboratory at Oxford. There he became involved in a fantastic, at that time almost unimaginable emerging project, for a European Laboratory, later to be called CERN. In 1954, he was nominated linkman between CERN and the company (Metropolitan Vickers), which had obtained the contract for the construction of the linear accelerator for the proton synchrotron, the PS, which was the first large project and "raison d'être" of the new ...

Oreochromis mossambicus were fed 5% of their body mass per day for 45 days, and those fed the experimental diets showed a greater increase in mass (111-139%) over the 45 days compared to those that received the control diet (98%). The specific growth rate of O. mossambicus fed the four diets was also significantly greater (1.66-1.93%) than control (1.52%) diet-fed fish. The blood plasma chemistry analysis revealed that protein, albumin, globulin, cholesterol, glucose and triglyceride levels of experimental fish were significantly higher than that of control fish. Packed cell volume of the blood samples of experimental diet-fed fish was also significantly higher (34.16-37.95%) than control fish (33.0%). Leucocrit value, phagocytic index and lysozyme activity were enhanced in fish fed the plant extract-supplemented diets. The acetone extract of the plants inhibited growth of Vibrio spp. and P. damselae with extracts from W. somnifera showing maximum growth inhibition. A challenge test with V. vulnificus showed 100% mortality in O. mossambicus fed the control diet by day 15, whereas the fish fed the experimental diets registered only 63-80% mortality at the end of challenge experiment (30 days). The cumulative mortality index for the control group was 12,000, which was equated to 1.0% mortality, and accordingly, the lowest mortality of 0.35% was registered in H(4)-diet-fed group.

    Full Text Available The use of some biota as bioindicators of heavy metal pollution has been demonstrated as particularly adequate due to their capacity of bioconcentration. This study evaluated the levels of platinum group metals (PGMs in some selected species along the coastal belt of Ghana, using the neutron activation analysis (NAA method. The result was processed to evaluate pollution indices in order to map the distribution of the metals in those species in the lagoons and estuaries along the costal belt of Ghana. The analysis showed significant levels of all PGMs in blackchin tilapia (Sarotherodon melanotheron Cichlidae, brown goby (Chonophorus lateristriga Gobiidae, shrimp (Macrobrachium vollenhovenii Palaemonidae, and mangrove oysters (Crassostrea tulipa Ostreidae in the lagoons and river Pra estuary. However, the oysters showed an elevated mean concentration of 0.13 μ/g (dry weight Pd. From the pollution indices, most of the sampling sites registered mean contamination factor (CF values between 1.20 and 3.00 for Pt, Pd, and Rh. The pollution load index (PLI conducted also gave an average pollution index between 0.79 and 2.37, indicating progressive contamination levels. The results revealed that anthropogenic sources, industrial and hospital effluent, etc., together with vehicular emissions, could be the contributing factors to the deposition of PGMs along the Ghanaian coast.

  5. Impact of acadja fisheries on the population dynamics of Sarotherodon melanotheron and Hemichromis fasciatus in a Lake Nokoué (Benin, West Africa

    Full Text Available In Lake Nokoué fishermen have developed the acadjas system which operates as an extensive aquaculture practice. Little is known about the population dynamics of fish fauna which colonizes those acadjas. Therefore, population parameters of two cichlids of Lake Nokoué, Sarotherodon melanotheron and Hemichromis fasciatus, sampled in areas within and without acadjas were investigated using length-frequency data collected between June 2003 and December 2004. For the two species, asymptotic length, L∞ was higher within than without acadjas (26.8 cm and 24.1 cm respectively for S. melanotheron; 18.5 cm and 16.5 cm respectively for H. faciatus. K and Φ′ values recorded outside acadjas were higher than inside acadjas for H. fasciatus whereas the same values were very slightly different without and within acadjas for S. melanotheron. H. fasciatus is a fish predator and branches or woody debris of acadjas are not favourable for its hunting activities.The total and natural mortality rates for the two species were higher outside than inside acadjas showing so the role of protection insured by acadjas systems. Acadjas have more impact on H. fasciatus than on S. melanotheron. A possibility of management is to reorganize the distribution of acadjas over Lake Nokoué in order to keep some areas in which no acadjas would be allowed for fish species that growth is better without acadjas.

    Snodgrass, Herschel B.

    2009-01-01

    It is with great sadness that I report the passing of Peter Robert Wilson, a well-known and well-loved figure in the solar physics community. Peter was on the faculty of the Department of Applied Mathematics at the University of Sydney for 39 years, and Chair of the department for 24 of these years. He was the author or co-author of more than 80 scientific research papers and a book, Solar and Stellar Activity Cycles (1994), published by Cambridge University Press. He died suddenly of a heart attack, at his home in Glebe, Australia, in the early morning of 11 November 2007. Peter was an organizer of, and participant in, many international conferences and workshops. He traveled extensively, holding visiting appointments at the University of Colorado (JILA), at Cambridge University, at the College de France (Paris), and at the California Institute of Technology [CalTech]. Most of his work was in the field of solar physics, but he also did some work on the philosophy of science and on tides. Peter came from a line of mathematicians. His father, Robert Wilson, immigrated to Australia from Glasgow in 1911, and became a mathematics teacher at Scotch College, a private school in Melbourne. There his name was changed to 'Bill' because 'Bob' was already taken." Peter's enjoyment of this story as characteristic of Australian academia (as any fan of Monty Python would understand) is indicative of his infectious sense of humor. In a similar vein, he claimed ancestry traced back to the eighteenth-century Scottish mathematician Alexander Wilson, Professor of Astronomy at the University of Glasgow. That Wilson is famous in the solar physics community for his discovery, known as the "Wilson Effect," of the photospheric depressions associated with sunspots. Peter himself could not resist writing a paper on this subject, and was delighted when the bait was taken by some less-informed colleagues who chided him for "naming an effect after himself." "Bill" Wilson married Naomi

    The toxic effects of two herbicides Round up (gliphosate) and 2,4-D (herbazol) were tested on Pistia stratiotes (Linn. Araceae) samples cultivated in glass aquariums. The gliphosate appears to be more toxic on Pistia Stratiotes than 2,4-D. It was then tested on tilapia Sarotherodon melanotheron juveniles. The lethal dose for tilapia (CL50 = 13.25 mg.l -1) is about 18, 37 and 74 times higher than the glyphosate toxic dose for plants at 1, 2 and 4 meters water depth respectively.

    Subramanian, Periasamy; Bupesh, Giridharan

    2011-06-01

    Experiments were conducted to determine the effects of Zinc oxide (ZnO) nanoparticles (NPs) on fish models. Oreochromis mossambicus was orally administered with ZnO NPs (50-100 nm) once and its effects at five different concentrations (60 ppm-100 ppm) were observed for 12 days. Enzymatic assays were performed at every three days interval in the vital tissues of liver, gill, muscle and kidney. The defense enzymes, ethoxyresorufin O-deethylase (EROD) and glutathione S transferase (GST) exerted a dose dependent elevation up to 6 days. This hike then declines in higher concentrations and extended duration. Whereas the tissue damaging enzymes, glutamate oxaloacetic transaminase (GOT), glutamate pyruvic transaminase (GPT) and alkaline phosphatase (ALP) as well as the antioxidant enzymes superoxide dismutase (SOD), catalase (CAT) exhibited a dose and duration dependent increase until the end of the experiment. Among these enzymes, the antioxidant enzymes response to ZnO NP toxicity on fish showed notable continuous induction. This study demonstrates that antioxidant enzymes responses in O. mossambicus could be used as a biomarker for the early detection of nanotoxicity.

    In most teleost fishes, sperm cells are quiescent in the seminal plasma and are activated by either a drop (fresh water fish) or an increase in osmolality (marine fish) when released in the water. It is most interesting to examine how the mechanisms of sperm motility activation can adapt to a broad range of salinities, as applies to some euryhaline species, and particularly to the tilapia Sarotherodon melanotheron heudelotii, which can reproduce at salinities from 0 up to 120 in the wild. Here, the gonado-somatic index, semen characteristics, and the osmotic and ionic requirements of sperm motility activation were compared in S. m. heudelotii reared in fresh water (FW), sea water (SW), or hypersaline water (HW; salinities of 0, 35, and 70, respectively). No salinity-dependent differences were found in gonado-somatic index or semen characteristics, except for an increase of seminal plasma osmolality with increasing salinity (from 318 to 349 mOsm kg(-1) in FW and HW fish, respectively). The osmolality range allowing the highest percentages of sperm activation broadened and shifted toward higher values with increasing fish ambient salinity (150-300, 300-800, and 500-1200 mOsm kg(-1), for FW, SW, and HW fish, respectively). Nevertheless, at the three fish rearing salinities, sperm could be activated in media that were hypotonic, isotonic, or hypertonic relative to the seminal plasma, at least when some calcium was present above a threshold concentration. The [Ca(2+)] required for the activation of S. m. heudelotii sperm is (1) higher in fish reared at a higher salinity (2) higher in hypertonic than that in hypotonic activation media, whatever the fish rearing salinity, and (3) higher in the presence of Na(+) or K(+), the negative effects of which increased with an increase in fish rearing salinity. The [Ca(2+)]/[Na(+)] ​ ratios allowing for maximal sperm motility in SW or HW fish are close to those observed in natural environments, either in sea or hypersaline

    The African cichlid Oreochromis mossambicus (Mozambique tilapia) has been used as a model system in a wide range of behavioural and neurobiological studies. The increasing number of genetic tools available for this species, together with the emerging interest in its use for neurobiological studies, increased the need for an accurate hodological mapping of the tilapia brain to supplement the available histological data. The goal of our study was to elaborate a three-dimensional, high-resolution digital atlas using magnetic resonance imaging, supported by Nissl staining. Resulting images were viewed and analysed in all orientations (transverse, sagittal, and horizontal) and manually labelled to reveal structures in the olfactory bulb, telencephalon, diencephalon, optic tectum, and cerebellum. This high resolution tilapia brain atlas is expected to become a very useful tool for neuroscientists using this fish model and will certainly expand their use in future studies regarding the central nervous system.

Scales were subjected to acid treatment for demineralization before it undergoes thermal extraction process. The raw scales were characterized via Scanning Electron Microscopy (SEM), which demarcated the cycloid pattern of the scales. SEM images also reveal the presence of collagen fiber in the fish scale. The black tilapia fish scales yields 11.88 % of gelatin, indicating the possibility of this fish species as sources of gelatin. Further characterizations were done on both raw scale and extracted gelatin through Fourier Transform Infrared Spectroscopy (FTIR) and proximate analysis. The scale gelatin shows high protein content (86.9 %) with low moisture (8.2 %) and ash (1.4 %). This further proves the effectiveness of the demineralization and extraction method used. The black tilapia fish scale is found to be a prospective source of gelatin with good chemical and functional properties.

Male Mozambique tilapia (Oreochromis mossambicus) use urine to signal dominance; furthermore, 5β-pregnane-3α,17,20β-triol-3α-glucuronide (and its α-epimer, 5β-pregnane-3α,17,20α-triol-3α-glucuronide), in their urine is a potent pheromone, the concentration of which is correlated with social status. The Nile tilapia (Oreochromisniloticus) is a close relative; species divergence probably resulted from geographical separation around 6 million years ago. This raises the question of whether the two species use similar urinary chemical cues during reproduction. The olfactory potency of urine, and crude extracts, from either species was assessed by the electro-olfactogram and the presence of the steroid glucuronides in urine from the Nile tilapia by liquid-chromatography/mass-spectrometry. Both species showed similar olfactory sensitivity to urine and respective extracts from either species, and similar sensitivity to the steroid glucuronides. 5β-Pregnan-3α,17α,20β-triol-3α-glucuronide was present at high concentrations (approaching 0.5mM) in urine from Nile tilapia, with 5β-pregnan-3α,17α,20α-triol-3α-glucuronide present at lower concentrations, similar to the Mozambique tilapia. Both species also had similar olfactory sensitivity to estradiol-3-glucuronide, a putative urinary cue from females. Together, these results support the idea that reproductive chemical cues have not been subjected to differing selective pressure. Whether these chemical cues have the same physiological and behavioural roles in O. niloticus as O. mossambicus remains to be investigated. Copyright © 2014 Elsevier Inc. All rights reserved.

    Peter Eklund grew up in Southern California and attended the University of California at Berkeley, majoring in physics. After working for one year at the Lockheed Missile and Space Company in Sunnyvale, California, he left to pursue graduate studies at Purdue University. There he carried out PhD research in strongly correlated electron and phonon systems under the supervision of J M Honig and L L van Zandt. Peter joined the group of Millie and Gene Dresselhaus at MIT in 1974 as a Postdoctoral Fellow after one year as an instructor at the University of Kentucky. At MIT, he continued work on strongly correlated systems in collaboration with Professor David Adler (who had an adjoining office), but for the most part he got excited about sp2 carbon systems and graphite intercalation compounds, a new research direction which the Dresselhaus group had started one year before Peter's arrival at MIT. Over the next 35 years Peter, Millie and Gene co-authored over 50 research articles, several review articles, and a big nine-hundred-and-fifty page book. In 1974, they saw graphite intercalation compounds as a long-neglected research direction of great promise. They studied these new materials together over the next 16 years, focusing on their optical spectroscopy. Their pioneering vibrational spectroscopy studies provided a means to characterize the fundamental properties of carbon materials. Optical spectroscopy became a centerpiece in the research portfolios of all three, both when they were together at MIT and after Peter left for the University of Kentucky in 1977 to start his independent career as an Assistant Professor of Physics. Peter became a full Professor at Kentucky in 1986. He continued to work with Millie and Gene and also acquired an ever-expanding network of students, postdocs and collaborators. As each new carbon nanostructure emerged—graphite intercalation compounds, fullerenes, carbon nanotubes, and most recently graphene—Peter was at the cutting edge

    The potential protective role of Tribulus terrestris in acetaminophen-induced hepatotoxicity in Oreochromis mossambicus was investigated. The effect of oral exposure of acetaminophen (500 mg/kg) in O. mossambicus at 24-h duration was evaluated. The plant extract (250 mg/kg) showed a remarkable hepatoprotective activity against acetaminophen-induced hepatotoxicity. It was judged from the tissue-damaging level and antioxidant levels in liver, gill, muscle and kidney tissues. Further acetaminophen impact induced a significant rise in the tissue-damaging level, and the antioxidant level was discernible from the enzyme activity modulations such as glutamate oxaloacetic transaminase, glutamate pyruvic transaminase, alkaline phosphatase, acid phosphatase, glucose-6-phosphate dehydrogenase, lactate dehydrogenase, superoxide dismutase, catalase, glutathione peroxidase, glutathione reductase, glutathione S-transferase, lipid peroxidase and reduced glutathione. The levels of all these enzymes have significantly (p terrestris extract (250 kg/mg). Histopathological changes of liver, gill and muscle samples were compared with respective controls. The results of the present study specify the hepatoprotective and antioxidant properties of T. terrestris against acetaminophen-induced toxicity in freshwater fish, O. mossambicus.

    Peter Becker was a German neurologist who helped classify the muscular dystrophies, and described Becker muscular dystrophy and Becker myotonia. His involvement in National Socialism began in 1933, when he was compelled by his peers to join the SA (brown shirts). He later joined the Nazi party......, the Nazi Doctors Association, and the Nazi Lecturers' Association. He renewed his SA membership to maintain his position at a genetics institute. Colleagues stated postwar that he was not an active Nazi, and he was de-Nazified in 1947, able to continue his career. Later, Becker admitted to most......, but not all, of his Nazi memberships in his autobiography, and wrote 2 books exploring the origins of Nazism and racial hygiene. The "neurologic court of opinion" must weigh in on how we should best remember Becker, and at the very least, we as neurologists must learn the dangers of career opportunism at any...

  9. The Social Dynamics of the Peter Principle

    Directory of Open Access Journals (Sweden)

    P. Fiedor

    2015-01-01

    Full Text Available In this paper the author presents a critique of the recent computational studies looking at efficient promotion strategies in hierarchical organisations [1, 2], and presents his own study, more applicable for socio-economic systems. While previous research based on the Peter Principle [3] is an interesting and fresh (though grounds have been laid by [4] view on the problem of organisational efficiency, they do lack psychological and sociological basis so important in social sciences [5, 6]. Therefore the advice saying that it may be beneficial to promote worst employees or employees at random is not based on sound methodological grounds of social sciences [7]. In this paper two mechanisms are introduced to the model proposed by [1], which bring the computational study closer to real life organisations, rendering the analysis more enlightening for them and their strategies. The first introduces social dynamics allowing agents to conform to the perceived expectations of the organisation, and the latter frees the model from univariate analysis of the competence of an agent together with the crude mechanisms for its propagation between positions, exchanging it for multivariate analysis with mechanism based on the classic research by Henri Fayol [8]. The results of these simulations allow the author to conclude that despite the fact that Peter was right in principle; in real organisations the best way to promote employees is to choose the best employees, which is in agreement with the reality of most organisations [9]. The paper underlines the need to use the methodology of social science in econophysics.

    Air Force Major Peter Hoag stands in front of the HL-10 Lifting Body. Maj. Hoag joined the HL-10 program in 1969 and made his first glide flight on June 6, 1969. He made a total of 8 flights in the HL-10. They included the fastest lifting-body flight, which reached Mach 1.861 on Feb. 18, 1970. The HL-10 was one of five heavyweight lifting-body designs flown at NASA's Flight Research Center (FRC--later Dryden Flight Research Center), Edwards, California, from July 1966 to November 1975 to study and validate the concept of safely maneuvering and landing a low lift-over-drag vehicle designed for reentry from space. Northrop Corporation built the HL-10 and M2-F2, the first two of the fleet of 'heavy' lifting bodies flown by the NASA Flight Research Center. The contract for construction of the HL-10 and the M2-F2 was $1.8 million. 'HL' stands for horizontal landing, and '10' refers to the tenth design studied by engineers at NASA's Langley Research Center, Hampton, Va. After delivery to NASA in January 1966, the HL-10 made its first flight on Dec. 22, 1966, with research pilot Bruce Peterson in the cockpit. Although an XLR-11 rocket engine was installed in the vehicle, the first 11 drop flights from the B-52 launch aircraft were powerless glide flights to assess handling qualities, stability, and control. In the end, the HL-10 was judged to be the best handling of the three original heavy-weight lifting bodies (M2-F2/F3, HL-10, X-24A). The HL-10 was flown 37 times during the lifting body research program and logged the highest altitude and fastest speed in the Lifting Body program. On Feb. 18, 1970, Air Force test pilot Peter Hoag piloted the HL-10 to Mach 1.86 (1,228 mph). Nine days later, NASA pilot Bill Dana flew the vehicle to 90,030 feet, which became the highest altitude reached in the program. Some new and different lessons were learned through the successful flight testing of the HL-10. These lessons, when combined with information from it's sister ship, the M2

  13. Solution of Peter Winkler's Pizza Problem

    Cibulka, Josef; Kynčl, Jan; Mészáros, Viola; Stolař, Rudolf; Valtr, Pavel

    Bob cuts a pizza into slices of not necessarily equal size and shares it with Alice by alternately taking turns. One slice is taken in each turn. The first turn is Alice's. She may choose any of the slices. In all other turns only those slices can be chosen that have a neighbor slice already eaten. We prove a conjecture of Peter Winkler by showing that Alice has a strategy for obtaining 4/9 of the pizza. This is best possible, that is, there is a cutting and a strategy for Bob to get 5/9 of the pizza. We also give a characterization of Alice's best possible gain depending on the number of slices. For a given cutting of the pizza, we describe a linear time algorithm that computes Alice's strategy gaining at least 4/9 of the pizza and another algorithm that computes the optimal strategy for both players in any possible position of the game in quadratic time. We distinguish two types of turns, shifts and jumps. We prove that Alice can gain 4/9, 7/16 and 1/3 of the pizza if she is allowed to make at most two jumps, at most one jump and no jump, respectively, and the three constants are the best possible.

    Full Text Available Mozambique tilapia, Oreochromis mossambicus, held in 30%o seawater and at 29-30 °C, were divided into four groups (n = 50/group in replicate, and given one of four feed cycles: 1 control, with continuous feedind, 2 5:5, 3 10:10 and 4 15:15, wherein fish were subjected to starvation and subsequent refeeding cycles of 5, 10 and 15 days respectively. All animals were fed a commercial diet containing 18.4% protein, 6.7% lipid, 58.6% carbohydrate and 7.2% ash, over a 60 day trial period. Growth compensation was observed in the feed cycled groups as increased (P < 0.03 weight specific growth rates during refeeding. However, feed cycled groups were unable to achieve the weghts of control fish. Starvation reduced (P<0.01 haematocrit values when compared to control levels and, in the 15:15 cycled groups, elevated the testicular index (P < 0.02. The results are considered with respect to the commercial application of compensatory growth during production of tilapia.

    Full Text Available Effects of different herbal extracts on the growth and immune defense of fish were researched in the last decade. The aim of this study was to determine the dietary effects of thyme (Thymus vulgaris, rosemary (Rosmarinus officinalis and fenugreek (Trigonella foenum graecum as a feed additive on haematology, innate immune response, and disease resistance of tilapia (Oreochromis mossambicus. In total 228 healthy fish tilapia were divided into four groups (57 fish in one group and fed diets supplemented with thyme, rosemary and fenugreek at levels of 1%, respectively; fish in the control group were fed diet without any spices. Fish were fed ad libitum three times a day for 45 days. All fish of the experimental groups significantly (P P P > 0.05 changed during the whole experiment. After 45 days of feeding, fish were injected intraperitoneally with 100 μl of Streptococcus iniae (8 × 108 colony forming unit. The cumulative mortality was 22%, 27% and 31% in fish receiving diets supplemented with 1% thyme, rosemary and fenugreek, respectively, compared to 61% mortality in the control group. The results indicate that all three supplements used improved the haematological status, non-specific immune response and disease resistance of tilapia against S. iniae; this is the first similar study.

    Radiotracer techniques were used to measure influx and efflux rates of Ca 2+ in freshwater-adapted Oreochromis mossambicus. The influx rate of Ca 2+ is related to body weight (W) as Fin = 50W0.805 nmol Ca 2+ /h. For a 20-g fish the calculated influx rate was 558 nmol Ca 2+ /h, and this was attributed largely to extraintestinal uptake since the drinking rate was estimated to be only 28 microliter water/h, which corresponds to an intake of 22.4 nmol Ca 2+ /h. The Ca 2+ efflux rate was calculated using the initial rate of appearance of radiotracer in the ambient water and the specific activity of plasma Ca 2+ . Tracer efflux rates were constant over 6-8 h, which indicated that there was no substantial loss of tracer in either the urine or the feces because this would have resulted in random bursts of tracer loss. Efflux rates then primarily represent integumentary and presumably branchial efflux rates. The efflux rate of Ca 2+ is related to body weight as Fout = 30W0.563 nmol Ca 2+ /h, which means an efflux rate of 162 nmol Ca 2+ /h for a 20-g fish. The net whole-body Ca 2+ influx, calculated as Fnet = Fin - Fout, was 396 nmol/h for a 20-g fish, which proves that the ambient water is an important source of Ca 2+

    Black tilapia (Oreochromis mossambicus) fish head bones were evaluated for its possibilities in extracting gelatin. Head bones were subjected to pre-treatment with 3% of hydrochloric acid (HCl) for demineralization before undergoes thermal extraction process. The raw head bones were characterized via Scanning Electron Microscopy (SEM) in order to investigate the external and internal surface morphology. SEM images also reveal the presence of collagen fiber with 1 µm diameter in the head bone. The black tilapia fish head bones yields 5.75 % of gelatin in wet weight basis, indicating the possibility of this fish species as sources of gelatin. Further characterizations were done on both raw head bones and extracted gelatin through Fourier Transform Infrared Spectroscopy (FTIR) and proximate analysis. The head bones gelatin shows high protein (10.55%) and ash (3.11 %) content with low moisture. This further proves the effectiveness of demineralization and extraction method used. The black tilapia fish head bones are found to be a prospective source of gelatin with good chemical and functional properties.

    One of the largest river systems in South Africa, the Olifants River, has experienced significant changes in water quality due to anthropogenic activities. Since 2005, there have been various “outbreaks” of the inflammatory disease pansteatitis in several vertebrate species. Large-scale pansteatitis-related mortality events have decimated the crocodile population at Lake Loskop and decreased the population at Kruger National Park. Most pansteatitis-related diagnoses within the region are conducted post-mortem by either gross pathology or histology. The application of a non-lethal approach to assess the prevalence and pervasiveness of pansteatitis in the Olifants River region would be of great importance for the development of a management plan for this disease. In this study, several plasma-based biomarkers accurately classified pansteatitis in Mozambique tilapia (Oreochromis mossambicus) collected from Lake Loskop using a commercially available benchtop blood chemistry analyzer combined with data interpretation via artificial neural network analysis. According to the model, four blood chemistry parameters (calcium, sodium, total protein and albumin), in combination with total length, diagnose pansteatitis to a predictive accuracy of 92 percent. In addition, several morphometric traits (total length, age, weight) were also associated with pansteatitis. On-going research will focus on further evaluating the use of blood chemistry to classify pansteatitis across different species, trophic levels, and within different sites along the Olifants River.

The results indicated that C. mixta seed meal diets at 4 g kg -1 and 6 g kg -1 significantly (P < 0.05) enhances the survival rate, weight gain (WG), protein efficiency ratio (PER), specific growth rate (SGR), feed conversion ratio (FCR), and feed efficiency (FE) from weeks 1-4 when compared to control. C. mixta seed meals administered as feed supplements significantly (P < 0.05) enhanced the complement activity, phagocytic activity, respiratory burst activity, and lysosome activity in infected fish fed with 4 g kg -1 and 6 g kg -1 of C. mixta seed meal enriched diet from weeks 2-4. The cumulative mortality was lower in the fish fed with 4 g kg -1 and 6 g kg -1 of C. mixta seed meal enriched diets (15% and 18%) than with 2 g kg -1 diet (26%). The present investigation suggested that C. mixta seed meal enriched diet at 4 g kg -1 and 6 g kg -1 enhance the better growth performance, innate immunity, and disease resistance against A. hydrophilla in O. mossambicus.

    On 7 August 1954, the world 42 km marathon record holder, Jim Peters, collapsed repeatedly during the final 385 metres of the British Empire and Commonwealth Games marathon held in Vancouver, Canada. It has been assumed that Peters collapsed from heatstroke because he ran too fast and did not drink during the race, which was held in windless, cloudless conditions with a dry-bulb temperature of 28 degrees C. Hospital records made available to us indicate that Peters might not have suffered from exertional heatstroke, which classically produces a rectal temperature > 42 degrees C, cerebral effects and, usually, a fatal outcome without vigorous active cooling. Although Peters was unconscious on admission to hospital approximately 60 minutes after he was removed from the race, his rectal temperature was 39.4 degrees C and he recovered fully, even though he was managed conservatively and not actively cooled. We propose that Peters' collapse was more likely due to a combination of hyperthermia-induced fatigue which caused him to stop running; exercise-associated postural hypotension as a result of a low peripheral vascular resistance immediately he stopped running; and combined cerebral effects of hyperthermia, hypertonic hypernatraemia associated with dehydration, and perhaps undiagnosed hypoglycaemia. But none of these conditions should cause prolonged unconsciousness, raising the possibility that Peters might have suffered from a transient encephalopathy, the exact nature of which is not understood.

    Full Text Available The main objective of this study was to investigate mopane worm (Imbrasia belina as a protein source in the diet of Oreochromis mossambicus. One thousand five hundred O. mossambicus fingerlings (40 ± 2.5 g were fed five isonitrogenous, isolipidic and isoenergetic diets formulated to contain 30% crude protein and 20 MJ/kggross energy (dry matter basis for 51 days. Fifteen indoor rectangular concrete tanks (1.5 m3 connected to a recirculating system were used. Water temperature ranged between 27 and 29 °C. The diets were prepared by replacing fishmeal with mopane worm meal at 10%, 20%, 40% and 60%. The diets were coded D2, D3, D4 and D5 respectively. A control diet with no mopane worm meal was coded D1. The diets were fed to triplicate groups of O. mossambicus twice a day. Specific growth rate (SGR, Thermal-unit growth coefficient (TGC, protein efficiency ratio (PER and apparent digestibility coefficient (ADC increased with higher inclusion levels of mopane worm meal. Feed conversion ratio (FCR also improved with higher inclusion levels. However, the highest growth performance (SGR: 3.49%; FCR: 1.29 was recorded in fish fed the fishmeal based control diet. Protease, amylase and lipase activities were determined in the intestines. Both protease and amylase activity were significantly higher (P < 0.05 at high mopane worm inclusion levels. It is suggested that the high protein levels of the mopane worm diet elicited high protease activity. The health status of the fish was evaluated by examining the liver and intestine histology. There were no evident histological alterations of either liver or intestine as mopane worm meal inclusion levels increased. This showed that mopane worm meal may be a good candidate for the replacement of fishmeal in O. mossambicus diets. The highest profit index (1.67 was recorded in the 60% mopane worm inclusion level. The lowest profit index was in the control. More studies on mopane worm meal as a substitute

    Full Text Available EPA (Eicosapentaenoic acid and DHA (Docosahexaenoic acid content in common fresh water fish : mujahir (Oreochromis mossambicus after indirect heating were analysed. The aims of this study were to determine the effect of indirect heating process and α-tocopherol additions on both fatty acid stability.Lipids content in the mujahir fillets were extracted by Folch method using chloroform-metanol (2:1 mixture. Fatty acids in fish oil were converted to fatty acid methyl esters and then injected into gas chromatography to determine the EPA and DHA concentration. Operating condition of gas chromatography were programmed as follows: injection port temperature at 270 oC, detector at 280 oC, initial column temperature at 200 oC, and the final at 280 oC, the carrier gas was helium with flow rate of 10 ml per minute and temperature of column was increased gradually at 10 oC per minute. The effect of α-tocopherol addition on the stability of EPA and DHA was studied by adding α-tocopherol at 50 to 200 mg per kilogram sample before indirect heating process was carried out.The analysis of mujahir fish oil showed that the content of EPA and DHA in 100 grams fresh sample was 105 and 406,5 mg respectivelly. Indirect heating caused the EPA and DHA content decreased significantly. The addition of α-tocopherol results in a positive corelation between α-tocopherol concentration added and the decrease of EPA and DHA content during the heating process.   Keywords: fatty acid, eicosapentaenoic acid, docosahexaenoic acid

    The aim of the present study is to explore the distribution of nitric oxide synthase in the olfactory system of an adult teleost, Oreochromis mossambicus using neuronal nitric oxide synthase (nNOS) immunocytochemistry and nicotinamide adenine dinucleotide phosphate diaphorase (NADPHd) histochemistry methods. Intense nNOS immunoreactivity was noticed in several olfactory receptor neurons (ORNs), in their axonal extensions over the olfactory nerve and in some basal cells of the olfactory epithelium. nNOS containing fascicles of the ORNs enter the bulb from its rostral pole, spread in the olfactory nerve layer in the periphery of the bulb and display massive innervation of the olfactory glomeruli. Unilateral ablation of the olfactory organ resulted in dramatic loss of nNOS immunoreactivity in the olfactory nerve layer of the ipsilateral bulb. In the olfactory bulb of intact fish, some granule cells showed intense immunoreactivity; dendrites arising from the granule cells could be traced to the glomerular layer. Of particular interest is the occurrence of nNOS immunoreactivity in the ganglion cells of the nervus terminalis. nNOS containing fibers were also encountered in the medial olfactory tracts as they extend to the telencephalon. The NADPHd staining generally coincides with that of nNOS suggesting that it may serve as a marker for nNOS in the olfactory system of this fish. However, mismatch was encountered in the case of mitral cells, while all are nNOS-negative, few were NADPHd positive. The present study for the first time revealed the occurrence of nNOS immunoreactivity in the ORNs of an adult vertebrate and suggests a role for nitric oxide in the transduction of odor stimuli, regeneration of olfactory epithelium and processing of olfactory signals.

    Animal sexual reproduction relies on primordial germ cells (PGCs), the predecessors of the germ cell lineage, giving rise to either spermatogonia or oogonia after the completion of gonadal differentiation. There is limited information on the mechanism of PGC migration leading to the formation of the primordial gonad in Perciform fish. Oreochromis mossambicus, a tilapiine species, was investigated that is a commercially important aquaculture species in many parts of the world while in other areas it has become an invasive pest. Key components involved in PGC migration were identified, including the stromal-cell derived factor 1 (Om-sdf1a, Om-sdf1b) and the CXC receptor 4 (Om-cxcr4): both share conservation with existing model species. The spatial gene expression profiles were determined through transcript and protein analysis and displayed distinct localisation within the region of the developing gonad in larvae and within the adult gonads of certain cell populations. A recombinant Om-sdf1a was produced in Escherichia coli that activates Om-cxcr4 using a BRET-based yeast in vitro assay system, suggesting that it is structurally similar to the native Om-sdf1a and is appropriate for further structural studies. This study has improved understanding of the molecular basis of tilapia reproduction through investigation of gonad development, which may be important in the progression towards reproductive suppression methods to control tilapia populations in the wild. In addition, this research will facilitate developments in germ cell transplantation, an innovative technique that harnesses germ cell migration and allows the uptake of foreign germ cells, which differentiate to produce sperm or ova.

    Selenoproteins are ubiquitously expressed, act on a variety of physiological redox-related processes, and are mostly regulated by selenium levels in animals. To date, the expression of most selenoproteins has not been verified in euryhaline fish models. The Mozambique tilapia, Oreochromis mossambicus, a euryhaline cichlid fish, has a high tolerance for changes in salinity and survives in fresh water (FW) and seawater (SW) environments which differ greatly in selenium availability. In the present study, we searched EST databases for cichlid selenoprotein mRNAs and screened for their differential expression in FW and SW-acclimated tilapia. The expression of mRNAs encoding iodothyronine deiodinases 1, 2 and 3 (Dio1, Dio2, Dio3), Fep15, glutathione peroxidase 2, selenoproteins J, K, L, M, P, S, and W, was measured in the brain, eye, gill, kidney, liver, pituitary, muscle, and intraperitoneal white adipose tissue. Gene expression of selenophosphate synthetase 1, Secp43, and selenocysteine lyase, factors involved in selenoprotein synthesis or in selenium metabolism, were also measured. The highest variation in selenoprotein and synthesis factor mRNA expression between FW- and SW-acclimated fish was found in gill and kidney. While the branchial expression of Dio3 was increased upon transferring tilapia from SW to FW, the inverse effect was observed when fish were transferred from FW to SW. Protein content of Dio3 was higher in fish acclimated to FW than in those acclimated to SW. Together, these results outline tissue distribution of selenoproteins in FW and SW-acclimated tilapia, and indicate that at least Dio3 expression is regulated by environmental salinity.

    SUMMARY This study aimed to determine the regulation of the de novo myo-inositol biosynthetic (MIB) pathway in Mozambique tilapia (Oreochromis mossambicus) brain following acute (25 ppt) and chronic (30, 60 and 90 ppt) salinity acclimations. The MIB pathway plays an important role in accumulating the compatible osmolyte, myo-inositol, in cells in response to hyperosmotic challenge and consists of two enzymes, myo-inositol phosphate synthase and inositol monophosphatase. In tilapia brain, MIB enzyme transcriptional regulation was found to robustly increase in a time (acute acclimation) or dose (chronic acclimation) dependent manner. Blood plasma osmolality and Na+ and Cl− concentrations were also measured and significantly increased in response to both acute and chronic salinity challenges. Interestingly, highly significant positive correlations were found between MIB enzyme mRNA and blood plasma osmolality in both acute and chronic salinity acclimations. Additionally, a mass spectrometry assay was established and used to quantify total myo-inositol concentration in tilapia brain, which closely mirrored the hyperosmotic MIB pathway induction. Thus, myo-inositol is a major compatible osmolyte that is accumulated in brain cells when exposed to acute and chronic hyperosmotic challenge. These data show that the MIB pathway is highly induced in response to environmental salinity challenge in tilapia brain and that this induction is likely prompted by increases in blood plasma osmolality. Because the MIB pathway uses glucose-6-phosphate as a substrate and large amounts of myo-inositol are being synthesized, our data also illustrate that the MIB pathway likely contributes to the high energetic demand posed by salinity challenge.

    Fish cell cultures are becoming more widely used models for investigating molecular mechanisms of physiological response to environmental challenge. In this study, we derived two immortalized Mozambique tilapia (Oreochromis mossambicus) cell lines from brain (OmB) and lip epithelium (OmL), and compared them to a previously immortalized bulbus arteriosus (TmB) cell line. The OmB and OmL cell lines were generated without or with Rho-associated kinase (ROCK) inhibitor/3T3 feeder layer supplementation. Although both approaches were successful, ROCK inhibitor/feeder layer supplementation was found to offer the advantages of selecting for epithelial-like cell type and decreasing time to immortalization. After immortalization (≥ passage 5), we characterized the proteomes of the newly derived cell lines (OmB and OmL) using LCMS and identified several unique cell markers for each line. Subsequently, osmotolerance for each of the three cell lines following acute exposure to elevated sodium chloride was evaluated. The acute maximum osmotolerance of these tilapia cell lines (>700 mOsm/kg) was markedly higher than that of any other known vertebrate cell line, but was significantly higher in the epithelial-like OmL cell line. To validate the physiological relevance of these tilapia cell lines, we quantified the effects of acute hyperosmotic challenge (450 mOsm/kg and 700 mOsm/kg) on the transcriptional regulation of two enzymes involved in biosynthesis of the compatible organic osmolyte, myo-inositol. Both enzymes were found to be robustly upregulated in all three tilapia cell lines. Therefore, the newly established tilapia cells lines represent valuable tools for studying molecular mechanisms involved in the osmotic stress response of euryhaline fish. PMID:24797371

    Osmoregulation in fish is a complex process that requires the orchestrated cooperation of many tissues. In fish facing hyperosmotic environments, the intestinal absorption of some monovalent ions and the secretion of bicarbonate are key processes to favor water absorption. In the present study, we showed that bicarbonate levels in the intestinal fluid are several fold higher in seawater than in freshwater acclimated tilapia (Oreochromis mossambicus). In addition, we analyzed gene expression of the main molecular mechanisms involved in HCO 3 - movements i.e. slc26a6, slc26a3, slc4a4 and v-type H-ATPase sub C in the intestine of tilapia acclimated to both seawater and freshwater. Our results show an anterior/posterior functional regionalization of the intestine in tilapia in terms of expression patterns, which is affected by environmental salinity mostly in the anterior and mid intestine. Analysis of bicarbonate secretion using pH-Stat in tissues mounted in Ussing chambers reveals high rates of bicarbonate secretion in tilapia acclimated to seawater from anterior intestine to rectum ranging between ~900 and ~1700nmolHCO 3 - cm -2 h -1 . However, a relationship between the expression of slc26a6, slc26a3, slc4a4 and the rate of bicarbonate secretion seems to be compromised in the rectum. In this region, the low expression of the bicarbonate transporters could not explain the high bicarbonate secretion rates here described. However, we postulate that the elevated v-type H-ATPase mRNA expression in the rectum could be involved in this process. Copyright © 2017 Elsevier Inc. All rights reserved.

    The interaction between the fish Oreochromis mossambicus (Percifomes: Cichlidae) and aquatic insects after application of chicken, cow, and pig manure was studied in 7,000-liter plastic aquadams. Principal component analysis showed that most of the variation in water quality after application of manure was accounted for by potassium, nitrogen, dissolved oxygen, phosphate, and alkalinity. Canonical correspondence analysis showed that Gyrinidae, Elminidae, Hydrophilidae, Hydraenidae, and Athericidae were associated with high nutrient levels (nitrogen, phosphorus, and potassium) characteristic of the chicken manure. However, the most abundant aquatic insects Gerridae, Notonectidae, and Culicidae were close to the centre of the ordination and not defined by any nutrient gradient. The Shannon-Wiener diversity was highest in the aquadams treated with chicken manure. The most frequently occurring aquatic insects in the diet of O. mossambicus were culicid mosquitoes in all the treatments. However, in the laboratory, Chironomidae were the most preferred because they lacked refuge. Notonectidae and Gerridae were not recorded in the diet of O. mossambicus despite their abundance. This may be because of their anti-predation strategies. Laboratory experiments showed that Notonectidae, Gyrinidae, and Gerridae fed on Chironomidae and Culicidae. This implies that aquatic predatory insects competed for food with O. mossambicus. © The Authors 2015. Published by Oxford University Press on behalf of Entomological Society of America.

    In this research, we focused on the efficacy of aqueous and ethanol leaf extracts of Psidium guajava L. (guava) based experimental diets on the growth, immune, antioxidant and disease resistance of tilapia, Oreochromis mossambicus following challenge with Aeromonas hydrophila. The experimental diets were prepared by mixing powdered (1, 5 and 10 mg/g) aqueous and ethanol extract of guava leaf with commercial diet. The growth (FW, FCR and SGR), non-specific cellular immune (myeloperoxidase activity, reactive oxygen activity and reactive nitrogen activity) humoral immune (complement activity, antiprotease, alkaline phosphatase activity and lysozyme activity) and antioxidant enzyme responses (SOD, GPX, and CAT) were examined after 30 days of post-feeding. A significant enhancement in the biochemical and immunological parameters of fish were observed fed with experimental diets compared to control. The dietary supplementation of P. guajava leaf extract powder for 30 days significantly reduced the mortality and increased the disease resistance of O. mossambicus following challenge with A. hydrophila at 50 μl (1 × 10 7  cells ml -1 ) compared to control after post-infection. The results suggest that the guava leaf extract could be used as a promising feed additive in aquaculture. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Full Text Available This study was conducted to investigate the effect of dietary cumin (Cuminum cyminum powder (CP as a feed additive on growth performance and disease resistance during first-feeding of Mozamique tilapia (Oreochromis mossambicus. Five isonitrogenous (40% crude protein and isocaloric (18.9 kj g-1 diets were formulated to contain 0 (control, 0.5, 1, 1.5, and 2.0% CP. In a 45-day feeding trial, 15 plastic tanks (21 L were stocked with 40 fry (0.012 ± 0.001 g each. After feeding experiment, fish were infected with Streptococcus iniae and mortalities were recorded. The second-order polynomial regression indicated that a dietary CP level of 1.14% provided the best survival rate challenge infection with S. iniae, growth performance and feed utilization. In conclusion, CP can be used as growth promoter to improve feed utilization and weight gain in tilapia fry, and it can be also used as an antimicrobial agent during first-feeding of O. mossambicus. Therefore, CP can be suggested as an alternative to antibiotics in controlling streptococcal disease in tilapia culture.

    Full Text Available Five species of Cyprinodon in Laguna Chichancanab, Yucatan, Mexico comprise a young species flock whose ecology and evolution has not been thoroughly studied, but whose existence is threatened with extinction. Species flocks evolve in isolated areas where predators and competitors are absent. Since the description of the Chichancanab flock, Oreochromis mossambicus, a species introduced into the lake for which I examined habitat in the 1980’s, has become common throughout the basin. I assessed relative abundance of flock species in the lake. examined habitat use and segregation among the three most common flock species and examined the affects of O. mossambicus upon flock species habitat use. Cyprinodon beltrani was the most abundant flock species in 1997, followed by C. maya and C. labiosus; C. verecundus and C. simus were rare. Cyprinodon beltrani was found in shallow water, nearshore, over thick beds of submerged Chara, and little emergent vegetation Cyprinodon beltrani exhibited diurnal variation in nearshore habitat use. In the field, the habitat use of C. beltrani and O. mossambicus broadly overlapped. In aquarium experiments, three flock species exhibited habitat use segregation and C. beltrani and C. labiosus showed agonistic behaviors that strengthened segregation. Cyprinodon maya differed from C. beltrani and C. labiosus by its greater dispersion of individuals and use of areas higher in the water column. The presence of O. mossambicus caused a shift in habitat use by C. maya and C. labiosus that put these species into habitat occupied by C. beltrani. The presence of introduced species has caused a significant perturbation of the conditions that fomented speciation of the Chichancanab flock 8000 years ago.Cinco especies de Cyprinodon en la Laguna Chichancanab, Yucatán, México comprenden un cardumen jóven de especies cuya ecología y evolución no ha sido estudiada a fondo, pero cuya existencia está siendo amenazada con la extinci

    Full Text Available Abstract Background Elizabethkingia spp. are opportunistic pathogens often found associated with intravascular device-related bacteraemias and ventilator-associated pneumonia. Their ability to exist as biofilm structures has been alluded to but not extensively investigated. Methods The ability of Elizabethkingia meningoseptica isolate CH2B from freshwater tilapia (Oreochromis mossambicus and E. meningoseptica strain NCTC 10016T to adhere to abiotic surfaces was investigated using microtiter plate adherence assays following exposure to varying physico-chemical challenges. The role of cell-surface properties was investigated using hydrophobicity (bacterial adherence to hydrocarbons, autoaggregation and coaggregation assays. The role of extracellular components in adherence was determined using reversal or inhibition of coaggregation assays in conjunction with Listeria spp. isolates, while the role of cell-free supernatants, from diverse bacteria, in inducing enhanced adherence was investigated using microtitre plate assays. Biofilm architecture of isolate CH2B alone as well as in co-culture with Listeria monocytogenes was investigated using flow cells and microscopy. Results E. meningoseptica isolates CH2B and NCTC 10016T demonstrated stronger biofilm formation in nutrient-rich medium compared to nutrient-poor medium at both 21 and 37°C, respectively. Both isolates displayed a hydrophilic cell surface following the bacterial adherence to xylene assay. Varying autoaggregation and coaggregation indices were observed for the E. meningoseptica isolates. Coaggregation by isolate CH2B appeared to be strongest with foodborne pathogens like Enterococcus, Staphylococcus and Listeria spp. Partial inhibition of coaggregation was observed when isolate CH2B was treated with heat or protease exposure, suggesting the presence of heat-sensitive adhesins, although sugar treatment resulted in increased coaggregation and may be associated with a lactose

    The transfer of the toxic heavy metal Cd from duckweed (Lemna minor L.) to the freshwater fish tilapia (Oreochromis mossambicus) was investigated. Concentrations of Cd in different chemical forms in duckweed and in different tissues (gut, edible muscle, and remnants or residual) of tilapia (i.e., ethanol-extractable fraction [F E ], HCl-extractable fraction [F HCl ], and residual fraction [F R ]) were quantified, and the bioaccumulation factors (BAFs) of Cd in the tilapia body were calculated. Simple linear regression analysis was used to unravel the correlation and accumulation mechanisms of Cd along the short food chain. Our results showed that with increasing exposure concentrations of Cd (0-50 μM for duckweed and 0-10 μM for tilapia), the total, F E (F e,d )-, F HCl (F h,d )-, and F R (F r,d )-Cd concentrations in duckweed and different tissues of tilapia increased progressively. The Cd sources (aqueous or dietary) influenced the BAF for Cd accumulation in the whole body of tilapia. Furthermore, regression analyses yielded significant positive correlations (R 2 > 0.96) between the Cd concentration in duckweed and in both the 3 parts and the whole body of tilapia. This finding suggests that Cd transfer from duckweed to tilapia can be quantitatively evaluated when tilapia is exposed only to duckweed. In addition, the linear regression between Cd accumulation in whole tilapia and F e,d -, F h,d -, and F r,d -Cd showed that particularly the correlation with F e,d -Cd is statistically significant (p < 0.001). The accumulated Cd concentrations and chemical forms in tilapia tissues also positively correlated with Cd sources (solution or duckweed). Compared with waterborne exposure only, duckweed especially increased the accumulation of Cd in the gut of tilapia. Taken together, our findings support a strong dependence of Cd accumulation and transfer from duckweed to tilapia on its chemical forms, especially on F e,d -Cd. This knowledge may expedite more

    2004-01-01

    We established a method of directly detecting Clostridium botulinum type C cells, while minimizing spore detection, in the intestinal contents of Mozambique tilapia (Oreochromis mossambicus). This technique involved extraction of predominantly cellular DNA from tilapia intestinal tracts and used a polymerase chain reaction assay to detect presence of type C1 toxin gene. We consistently detected C. botulinum type C cells in tilapia gastrointestinal contents at a level of 7.5×104 cells per 0.25 g material or 1.9×103 cells. This technique is useful for determining prevalence of the potentially active organisms within a given population of fish and may be adapted to other types of C. botulinum and vertebrate populations as well.

  2. 5-HT receptor subtypes as key targets in mediating pigment dispersion within melanophores of teleost, Oreochromis mossambicus.

    2013-02-01

    The presence of distinct class of 5-HT receptors in the melanophores of tilapia (Oreochromis mossambicus) is reported. The cellular responses to 5-HT (5-hydroxytryptamine), 5-HT(1), and 5-HT(2), agonists on isolated scale melanophores were observed with regard to pigment translocation within the cells. It was found that 5-HT exerted rapid and strong concentration dependent pigment granule dispersion within the melanophores. The threshold pharmacological dose of 5-HT that could elicit a measurable response was as low as 4.7×10(-12) M/L. Selective 5-HT(1) and 5-HT(2) agonists, sumatriptan and myristicin were investigated and resulted in dose-dependent pigment dispersion. The dispersing effects were effectively antagonized by receptor specific antagonists. It is suggested that 5-HT-induced physiological effects are mediated via distinct classes of receptors that possibly participate in modulation of pigmentary responses of the fish.

    2004-07-01

    Tilapia (Oreochromis mossambicus) have been implicated as the source of type C toxin in avian botulism outbreaks in pelicans (Pelecanus erythrorhynchos, Pelecanus occidentalis californicus) at the Salton Sea in southern California (USA). We collected sick, dead, and healthy fish from various sites throughout the Sea during the summers of 1999 through 2001 and tested them for the presence of Clostridium botulinum type C cells by polymerase chain reaction targeting the C(1) neurotoxin gene. Four of 96 (4%), 57 of 664 (9%), and five of 355 (1%) tilapia tested were positive for C. botulinum type C toxin gene in 1999, 2000, and 2001, respectively. The total number of positive fish was significantly greater in 2000 than in 2001 (P<0.0001). No difference in numbers of positives was detected between sick and dead fish compared with live fish. In 2000, no significant relationships were revealed among the variables studied, such as location and date of collection.

    2014-09-01

    The aim of the present study was to assess the oxidative stress, antioxidant response and histopathological changes of nickel nanoparticles (Ni NPs) exposure (14 days) in Mozambique tilapia, Oreochromis mossambicus. Ni NPs were synthesized by metal salt reduction method and characterized by X-ray diffraction (XRD) and Transmission electron microscopy (TEM). The XRD peaks at 44°, 51° and 76° were indexed to the (111), (200) and (220) Bragg's reflections of cubic structure of Nickel, respectively. The crystallite sizes were calculated using Scherrer's formula applied to the major intense peaks and found to be the size of 56nm. TEM images showed that the synthesized Ni NPs are spherical in shape. Biochemical analysis indicated that the superoxide dismutase (SOD), catalase (CAT) and peroxidase (POD) activity was significantly affected by Ni NPs treated O. mossambicus. Reduced antioxidant enzymes and the contents of antioxidants were lowered in the liver and gills of fishes treated with Ni NPs. After 14 days of exposure, a significant accumulation of Ni in the Ni NPs in experimental group was observed in the gill and skin tissues, with the highest levels found in the liver. Ni NPs exposed fish showed nuclear hypertrophy (NH), nuclear degeneration (ND), necrosis (NC) and irregular-shaped nuclei were observed in liver tissue. The hyperplasia of the gill epithelium (GE), lamellar fusion of secondary lamellae (LF), dilated marginal channel (MC), epithelial lifting (EL) and epithelial rupture were observed in gill tissue. Degeneration in muscle bundles (DM), focal area of necrosis (NC) vacuolar degeneration in muscle bundles (VD), edema between muscle bundles (ED) and splitting of muscle fibers were noticed in skin tissue. Further ecotoxicological evaluation will be made concerning the risk of Ni NPs on aquatic environment. Copyright © 2014 Elsevier Inc. All rights reserved.

    Full Text Available Abstract: This article describes the life and work of the distinguished political leader of the 17th century Vasiliy Vasilyevich Golitsyn. He entered the history of our country as a thoughtful reformist and a brilliant diplomat. His transformations created the foundation for the future pivotal reforms by Peter the Great. Being an outstanding analyst and a strategic planner, Golytsin won his combats not on the bloody battlefields but in the course of fights on the diplomatic arena. During the reign of Sophia, when he had received ultimately unlimited power warrant, he mainly fostered all of his efforts to the implementation of the socio-economic changes and the rise of prestige of the Russian State. However, as it often happens with the prominent reformists he became a victim of the in-house political tussle; he placed the wrong bet on Sophia instead of Peter the Great and his court. As a result, he was deprived from his post, lost his estates, and was sent into exile to the north of the country. The author of this article followed the probable route of Golytsin’s exile ramblings and paid special attention to the stay of the disgraced knyaz in Pinezhskiy Volok - currently the settlement of Pinega situated approximately 200 km away from Arkhangelsk on the banks of the Pinega River. The article also offers a detailed description of the Krasnogorskiy Monastery located 15 km away from the settlement. Golitsyn used to visit this monastery regularly and in 1714 was buried there disclaimed by Peter. The tombstone from his grave was preserved and is now stored in the Museum of Regional Studies in Pinega.

    2002-01-01

    John Peters and his committee had a few basic goals. One was that local, state, and federal governments needed to provide money to construct facilities, support medical research and education, and care for the poor. And they wanted experts to call the shots. Over time, Peters and the committee got what they wanted for the most part: Hill-Burton money for building the hospitals, the rise of the National Institutes of Health, Medicare, Medicaid, a Veterans Administration system, and new and expanded medical schools. The experts calling the shots included David Kessler at the Food and Drug Administration and Surgeon General C. Everett Koop. In the halcyon days of American health system reform, back in 1993, Yale's Paul Beeson wrote about the Committee of 430 Physicians and its goals in the Pharos of Alpha Omega Alpha. Beeson was optimistic and he quoted from my 1991 JAMA health system reform editorial as a sharp contrast to what Fishbein had written - although coincidentally, we both quote Lincoln. My editorial began, "'with malice toward none, with charity for all...' so spoke Abraham Lincoln in his second inaugural address recognizing that he had no political consensus regarding either the constitutionality of states seceding or the morality of slavery being abolished. Nonetheless, he knew what was right and was able, through persuasive, often inspiring rhetoric, to conclude a bloody and decisive Civil War and constitute the foundation for this great republic.... Yet access to basic medical care for all of our inhabitants is still not a reality in this country. There are many reasons for this, not the least of which is a long-standing, systematic, institutionalized racial discrimination.... An aura of inevitablitiy is upon us. It is not acceptable morally, ethically, or economically for so many of our people to be medically uninsured or seriously underinsured. We can solve this problem. We have the knowledge and the resources, the skills, the time, and the moral

    1982-08-01

    The ichthyologically well-known teleostean fish, Lebistes reticulatus Peters commonly known as guppy, found abundant in pools, streams and estuaries was studied to establish its sensitivity to radiation and to explore its possible use as a biological indicator organism of radiation effects in the aquatic system. The guppy, Lebistes reticulatus was found to be radiosensitive. Chromosome aberrations were induced by gamma-irradiation of fish in vivo. Through cytogenetic technique the aberrant chromosomes were evaluated. The aberrant chromosomes observed were of various types such as chromatid gaps and breaks, chromosome gaps and breaks, chromatid and chromosome fragments, polycentrics (dicentrics and tricentrics), fusions and translocations. Of the types seen, it is concluded that dicentrics are the most reliable indicator of radiation effects. In the course of this study, the Lethal Radiation Dose in guppy within thirty days was determined. It was found to lie in the dose of 3 krad (LDsub(50/30)). (author)

    Professor Peter Higgs played a key role in the development of the Standard Model, our current theory of fundamental physics. The search for the Higgs Boson is the centrepiece of the LHC programme at CERN, and the existence of this famously elusive particle is likely to be confirmed or refuted with data currently being collected, using apparatus partly designed at Bristol. Professor Higgs will introduce the ideas of spontaneous symmetry breaking, and discuss how these developed from their application in condensed matter through the earlier work of Yoichiro Nambu and Jeffrey Goldstone, to the work of Robert Brout, Francois Englert and himself in 1964. The subsequent application of these ideas to electroweak theory will be discussed briefly.

    This study examined concentrations of 15 perfiuoroalkyl acids (PFAAs) in tissues from male Mozambique dlapia (Oreochromis mossambicus) collected at Loskop Dam,Mpumalanga,South Africa in 2014 and 2016.Nine of the 15 PFAAs were detected frequently and were included in statistical analysis and included two of the most commonly known PFAAs,perfluorooctanesulfonic acid (PFOS) (median,41.6 ng/g) and perfluorooctanoic acid (PFOA) (median,0.0825 ng/g).Of the tissues measured,plasma (2016 and 2014 median,22.2 ng/g) contained the highest PFAA burden followed by (in descending order):liver (median,11.6 ng/g),kidney (median,9.04 ng/g),spleen (median,5.92 ng/g),adipose (median,2.54 ng/g),and muscle (median,1.11 ng/g).Loskop Dam tilapia have been affected by an inflammatory disease of the adipose tissue known as pansteatitis,so this study also aimed to investigate relationships between PFAA tissue concentrations and incidence of pansteatitis or fish health status.Results revealed that healthy tilapia exhibited an overall higher (p-value < 0.05) PFAA burden than pansteatitis-affected tilapia across all tissues.Further analysis showed that organs previously noted in the literature to contain the highest PFAA concentrations,such as kidney,liver,and plasma,were the organs driving the difference in PFAA burden between the two tilapia groups.Care must be taken in the interpretations we draw from not only the results of our study,but also other PFAA measurements made on populations (human and wildhfe ahke) under differing health status.

    We studied the organization of the neuropeptide Y (NPY)-immunoreactive system in the forebrain of adult male cichlid fish Oreochromis mossambicus and its response to castration and testosterone replacement by using morphometric methods. Immunoreactivity for NPY was widely distributed in the forebrain, and the pattern generally resembled that in other teleosts. Whereas immunoreactivity was conspicuous in the ganglia of nervus terminalis (NT; or nucleus olfactoretinalis), a weak reaction was detected in some granule cells in the olfactory bulb and in the cells of area ventralis telencephali pars lateralis (Vl). Moderately to intensely immunoreactive cells were distinctly seen in the nucleus entopeduncularis (NE), nucleus preopticus (NPO), nucleus lateralis tuberis (NLT), paraventricular organ (PVO), and midbrain tegmentum (MT). NPY fibers were widely distributed in the forebrain. Castration for 10/15 days resulted in a drastic loss of immunoreactivity in the cells of NE (P<0.001) and a significant decrease (P<0.01) in their cell nuclear size. However, cell nuclei of the NT neurons showed a significant increase in size. A highly significant reduction in the NPY-immunoreactive fiber density (P<0.001) was observed in several areas of the forebrain. Although testosterone replacement reversed these changes, fibers in some areas showed supranormal responses. Immunoreactive cells in Vl, NPO, NLT, PVO, and MT and fiber density in some other areas did not respond to castration. We suggest that the NPY-immunoreactive elements that respond to castration and testosterone replacement may serve as the substrate for processing the positive feedback action of the steroid hormone.

    This study examined concentrations of 15 perfluoroalkyl acids (PFAAs) in tissues from male Mozambique tilapia (Oreochromis mossambicus) collected at Loskop Dam, Mpumalanga, South Africa in 2014 and 2016. Nine of the 15 PFAAs were detected frequently and were included in statistical analysis and included two of the most commonly known PFAAs, perfluorooctanesulfonic acid (PFOS) (median, 41.6ng/g) and perfluorooctanoic acid (PFOA) (median, 0.0825ng/g). Of the tissues measured, plasma (2016 and 2014 median, 22.2ng/g) contained the highest PFAA burden followed by (in descending order): liver (median, 11.6ng/g), kidney (median, 9.04ng/g), spleen (median, 5.92ng/g), adipose (median, 2.54ng/g), and muscle (median, 1.11ng/g). Loskop Dam tilapia have been affected by an inflammatory disease of the adipose tissue known as pansteatitis, so this study also aimed to investigate relationships between PFAA tissue concentrations and incidence of pansteatitis or fish health status. Results revealed that healthy tilapia exhibited an overall higher (p-valuetilapia across all tissues. Further analysis showed that organs previously noted in the literature to contain the highest PFAA concentrations, such as kidney, liver, and plasma, were the organs driving the difference in PFAA burden between the two tilapia groups. Care must be taken in the interpretations we draw from not only the results of our study, but also other PFAA measurements made on populations (human and wildlife alike) under differing health status.

  12. Not All Inner Ears are the Same: Otolith Matrix Proteins in the Inner Ear of Sub-Adult Cichlid Fish, Oreochromis Mossambicus, Reveal Insights Into the Biomineralization Process.

    Science.gov (United States)

    2016-02-01

    The fish ear stones (otoliths) consist mainly of calcium carbonate and have lower amounts of a proteinous matrix. This matrix consists of macromolecules, which directly control the biomineralization process. We analyzed the composition of this proteinous matrix by mass spectrometry in a shotgun approach. For this purpose, an enhanced protein purification technique was developed that excludes any potential contamination of proteins from body fluids. Using this method we identified eight proteins in the inner ear of Oreochromis mossambicus. These include the common otolith matrix proteins (OMP-1, otolin-1, neuroserpin, SPARC and otoconin), and three proteins (alpha tectorin, otogelin and transferrin) not previously localized to the otoliths. Moreover, we were able to exclude the occurrence of two matrix proteins (starmaker and pre-cerebellin-like protein) known from other fish species. In further analyses, we show that the absence of the OMP starmaker corresponds to calcitic otoliths and that pre-cerebellin-like protein is not present at any stage during the development of the otoliths of the inner ear. This study shows O. mossambicus does not have all of the known otolith proteins indicating that the matrix proteins in the inner ear of fish are not the same across species. Further functional studies of the novel proteins we identified during otolith development are required. © 2015 Wiley Periodicals, Inc.

    2007-10-01

    Immunostimulatory effects of the oral administration of the medicinal plant, Eclipta alba leaf extracts was studied in tilapia, Oreochromis mossambicus. For this purpose, fish were fed for 1, 2 or 3 weeks with diets containing E. alba leaf aqueous extract at 0, 0.01, 0.1 or 1% levels. After each week, non-specific humoral (lysozyme, antiprotease and complement) and cellular (myeloperoxidase content, production of reactive oxygen and nitrogen species) responses and disease resistance against Aeromonas hydrophila were determined. The results indicated that E. alba aqueous extract administered as feed supplement significantly enhanced most of the non-specific immune parameters tested. Among the humoral responses, lysozyme activity significantly increased after feeding with aqueous extract for 1, 2 or 3 weeks. No significant modulation was noticed in all the cellular responses tested after 3 weeks of feeding, while reactive oxygen species production and myeloperoxidase content showed significant enhancement after 1 week of feeding with aqueous extract. When challenged with A. hydrophila after 1, 2 or 3 weeks of feeding, the percentage mortality was significantly reduced in the treated fish. The highest dose of 1% gave better protection than the other doses with the relative percentage survival (RPS) values of 64, 75 and 32 after feeding for 1, 2 and 3 weeks respectively. The results indicate that dietary intake of E. alba aqueous leaf extract enhances the non-specific immune responses and disease resistance of O. mossambicus against A. hydrophila.

    Full Text Available ResumenAcabada la Segunda Guerra Mundial, el Movimiento Moderno se debatió entre su continuidad o crisis, lo que llevó a numerosos arquitectos y críticos a formular teorías y adoptar actitudes disciplinares trasgresoras con el momento. Una de ellas fue la del arquitecto, urbanista y paisajista inglés Peter Shepheard quien desarrolló una actividad profesional, teórica y docente de la que se trasluce la relevancia del concepto in between como una de las claves defi nitorias del diseño arquitectónico en la segunda mitad del siglo XX. Para Shepheard el diseño moderno debía ser el encuentro entre la arquitectura, el urbanismo y el paisaje. Aseveración que vino precedida por diferentes tipos de obras arquitectónicas, proyectos urbanos, artículos y publicaciones sobre el diseño del paisaje y del jardínque le convirtieron en una voz de referencia en el contexto británico. Shepheard alentó a los paisajistas a convencerse de que las tres disciplinas anteriores convergen en un sola y que la responsabilidad de la joven profesión de arquitecto del paisaje es asumir el reto del diseño arquitectónico, urbano y paisajístico como un todo en la búsqueda y defi nición de espacios intermedios entre la arquitectura y el paisaje. AbstractAfter the Second World War, Modernism started to debate his continuity or crisis. This led many architects and critics to formulate theories and take up breaking disciplinary attitudes against that time. One of them was the English architect, urban planner and landscape designer Peter Shepheard who developed a professional, theoretical and academic career where the concept in between got relevance as one of the defi ning keys of the architectural design in the second half of the twentieth century. To Shepheard modern design should be the encounter between architecture, urbanism and landscape. This claim was preceded by different types of architectural works, urban projects, articles and publications on

    Full Text Available The study is devoted to Miloš Forman’s film, a story about Mozart’s life, taken from Peter Shaffer’s drama. The author proposes a detailed analysis of Forman’s film as an autonomous work in the production of which the film was a medium. The film was an effect of collaboration between the author of the play and the director. The effect of the work is a film which is an example of a close connection of the form and the content – harmony between picture and music, which becomes almost one of the main characters. Individual compositions of Mozart form a network of motives closely connected with the visual aspect and make its sense deeper according to several rules of showing music as a part of the film medium, such as musical motives, explaining the music by the composer or music which uses media. Connecting the music and the aesthetics of the film make Amadeus a harmonious audio-visual performance.

    One means of evaluating the hazards caused by radioactivity on the genomes of aquatic organisms is to screen the exposed cells for chromosome aberrations. Since fish comprise the majority of aquatic organisms, it will be very interesting to prepare and establish a baseline study of the chromosome numbers of this species. The Philippine guppy (Lebistes reticulatus Peter) collected from the different sampling areas were studied using the gill epithelial cells. These were studied to determine the chromosome number and the fundamental number of the species; to study the chromosome morphology and its karyotype. Cytogenetic techniques were used to analyze the chromosomes of the guppy. Of the karyotypes seen, it was concluded that the guppies collected from the three areas show no considerable differences. Apparently, no chromosomal abnormalities were seen in the cells analyzed. The karyotype was constructed to illustrate the chromosome morphology of the guppy. This constructed karyotype of the guppy can be used as a model for determining chromosome aberration effects on the component of the aquatic ecosystems. (author)

    Full Text Available Abstract: Haul is a tradition typical of Muslims in Indonesia. Although as a term, can be likened to haul in the tradition of pilgrimage of Muslims in general, but in Indonesia haul have different shapes and implementation in practice with the pilgrimage. This can be seen clearly as an institutionalized social activity. Meaning of pilgrimage as a reminder of death eventually not be the main objective in the implementation of the haul, although religious motives still underlie the practice. However haul relfeksi has become a kind of history, not just in view of the transience of human life, but rather the development of the vision and mission of human life further they get from the reflection of history celebrated figures. Making of history eventually become important to observe. History is not just a stretch of the past, present, and future, but, in the context of haul, history is closely related to building public awareness about the celebrated figures, either directly or through stories or media. Building awareness is what allows every individual who commemorate haul will internalize the objects of consciousness different from the historical reflection, although figures are presented objectively observed through individuals close to and understand objectively as himself. It is at least able to prove that religion is very closely linked to community activities. Keywords: Haul, Peter L. Berger, Sosiologi Pengetahuan dan Refleksi Sejarah.

    The paper examines central parts of the first of two papers in this journal by Peter Slezak criticising sociology of scientific knowledge and also considers, independently, some of the main philosophical issues raised by the sociologists of science, in particular David Bloor. The general conclusion is that each account alludes to different and crucial aspects of the nature of knowledge without, severally or jointly, being able to theorise them adequately. The appendix contains epistemological theses central to a more adequate theory of scientific knowledge.... our Histories of six Thousand Moons make no Mention of any other, than the two great Empires of Lilliput and Blefuscu. Which mighty Powers have ... been engaged in a most obstinate War for six and thirty Moons past. It began upon the following Occasion. It is allowed on all Hands, that the primitive Way of breaking Eggs before we eat them, was upon the larger End: But ... the Emperor [of Lilliput] ... published an Edict, commanding all his Subjects, upon great Penalties, to break the smaller End of their Eggs. The People so resented this Law, that ... there have been six Rebellions raised on that Account ... These civil Commotions were constantly fomented by the Monarchs of Blefuscu ... It is computed, that eleven Thousand have, at several Times, suffered Death, rather than break Eggs at the smaller End. Many hundred large Volumes have published upon this Controversy ...

  2. The Representation of Aboriginality in the Novels of Peter Temple

    2017-01-01

    Full Text Available Identity politics is fraught with difficulties. Of few places is this truer than in Australia when it comes to the representation of Aboriginality. On the one hand the absence or invisibility of Aboriginality in Australian life and culture maybe interpreted as a deliberate exclusion of a people whose presence is uncomfortable or inconvenient for many Australians of immigrant origin. Equally, the representation of Aboriginality by non-Aboriginals may be seen as an appropriation of identity, an inexcusable commercial exploitation or an act of neocolonialism. Best-selling and prize-winning South African-born author Peter Temple appears to be very much aware of these pitfalls. In his crime novels, written between 1996 and 2009, he has obviously made the decision to grasp the nettle and attempt to represent Aboriginality in a way that would be as acceptable as possible. This paper traces the evolution of Temple's representation of Aboriginality through the three major Aboriginal characters present in his novels: Cameron Delray (Bad Debts, 1996; Black Tide, 1999; Dead Point, 2000; and White Dog, 2003, Ned Lowey (An Iron Rose, 1998 and Detective Sergeant Paul Dove (The Broken Shore, 2005 and Truth, 2009.

    Full Text Available Growth towards maturity is dependent on the presence of freedom, holiness and immortality. These are presented as divine qualities that are utterly lacking in human beings. However, while human beings are ignorant and weak, sinful and mortal the addressees of 1 Peter1 are reminded that they have also been begotten anew by the imperishable seed of God’s Word, the Good News of Jesus Christ in order to share immortal life. This article looks first at human beings who as God’s creatures are ‘flesh’, but are also enabled to acknowledge their ‘fleshly’ state, to appreciate (‘desire’ and ‘taste’ (2:2–3 the Gospel and to submit to God. The second part considers the saving role of Christ as the powerful yet rejected ‘stone’ placed and offered by God as the model and means to transcend the ‘flesh’ in the flesh (4:1–2. A final part focuses on the new birth and the growth process in which the fleshly desires and ways of living give way to a manner of life, which is a witness to God’s saving power.

  16. The Image of God in the Second Epistle of Peter

    Directory of Open Access Journals (Sweden)

    Krzysztof Suszko

    2017-09-01

    Full Text Available An analysis of this text reveals the two essential issues handled in the epistle: (1 the constant presence of the theme of God considered from the viewpoint of His glory and (2 an ultimate Christocentrism of all content references in the image of God. The word “glory” (δόξα appears five times, always in key places of the inspired text under study. The epistle exposes the theology of faith from the aspects of knowledge and calling, so as to successively reveal the mystery of Jesus Christ being the Divine Person – in the context of the Divine Trinity – and, furthermore, to disclose His subsequent Christological titles leading to a complete revelation in the expression: “Our Lord and Savior, Jesus Christ” (κύριος ἡμῶν καὶ σωτήρ Ἰησοῦς Χριστός. At the same time, the epistle describes the main practical goal, i.e. “partaking of the divine nature” (cf. 2 Peter 1 : 4 through “God and Jesus, our Lord” (θεός καὶ Ἰησοῦς κύριος ἡμῶν, and the method of reaching this goal; it also warns against going a different way by contrasting the two dimensions of reality: the earthly and the eternal.

  18. Professor Peter Choyce: an early pioneer of intraocular lenses and corneal/refractive surgery.

    Pandey, Suresh K; Apple, David J

    2005-06-01

    Professor Peter Choyce, FRCS, DOMS, MS, was one of the pioneers of intraocular lens implant surgery. He developed an interest in artificial lens implantation following cataract surgery, a procedure that was widely criticized by the ophthalmic establishment in the UK, Europe, North America and other countries. Owing to the opposition to the intraocular lenses, Peter Choyce together with Sir Harold Ridley co-founded the International Intraocular Implant Club in 1966, which was responsible for the gradual acceptance of artificial lens implantation. Peter Choyce developed several models of intraocular lens, but did not patent the majority of them. The Choyce Mark IX, manufactured by Rayner Intraocular Lenses, became the first US Food and Drug Administration-approved intraocular lens in 1981. A review of Peter Choyce's record confirms a significant number of original innovations in the field of anterior segment surgery, including many procedures taken for granted today, but not associated with his name. These include early work on both kerato- and intraocular lens-refractive procedures, keratoprosthesis, pioneering paediatric implant procedures and others. Unfortunately his tenacious adherence to anterior chamber lens technology, while in general clinically sound, caused many to question his influence and hence he remained poorly understood even until after his death. He passed away on 8 August 2001 after a long fight with colon cancer. In this article, we provide evidence and elaborate Peter Choyce's accomplishments, which places him as one of the most innovative ophthalmologist in his surgical field in the twentieth century.

    Full Text Available A anomalia de Peters consiste na mais comum opacidade corneana congênita e é secundária à malformação do segmento anterior do olho. Suas principais características são opacidade corneana central e sinéquias da íris e/ou do cristalino com a região do leucoma. Pode apresentar-se de forma isolada ou associada a outras anomalias oculares e sistêmicas, tendo prognóstico mais sombrio nestes casos. A etiologia da anomalia Peters permanece incerta, sendo aventadas causas genéticas, infecciosas, traumáticas e tóxicas. O tratamento varia com a apresentação do quadro, sendo importante a pronta detecção da doença, possibilitando o tratamento precoce, com bom desenvolvimento da visão. Este trabalho relata um caso de anomalia de Peters diagnosticado tardiamente e discute as características da doença e possibilidades de tratamento.Peter's anomaly consists in the most common congenital corneal opacity related to a malformation of the anterior segment of the eye. Its main characteristics are central leukoma and iridocorneal adherences at the area affected by the leukoma. It can be identified isolated or in association with other ocular or systemic abnormalities, and the prognostic tend to be worse in the latter cases. The etiology of Peter's anomaly remains uncertain, but the most likely causes are related to genetic, infectious, traumatic and toxic factors. A range of possible treatment strategies exists, though the effectiveness of each of them depends on how the disease occurs and whether it is identified in early or advanced stages - the earlier the diagnosis, the higher the possibility of a successful intervention, given that precocious treatments are more likely to result in a good development of the vision. This work reports a case of Peter's anomaly that was diagnosed in an advanced stage, discussing the characteristics of the case and treatment possibilities.

  20. The 2009 Lindau Nobel Laureate Meeting: Peter Agre, Chemistry 2003.

    Agre, Peter

    2009-12-09

    Peter Agre, born in 1949 in Northfield Minnesota, shared the 2003 Nobel Prize in Chemistry with Roderick MacKinnon for his discovery of aquaporins, the channel proteins that allow water to cross the cell membrane. Agre's interest medicine was inspired by the humanitarian efforts of the Medical Missionary program run by the Norwegians of his home community in Minnesota. Hoping to provide new treatments for diseases affecting the poor, he joined a cholera laboratory during medical school at Johns Hopkins. He found that he enjoyed biomedical research, and continued his laboratory studies for an additional year after medical school. Agre completed his clinical training at Case Western Hospitals of Cleveland and the University of North Carolina, and returned to Johns Hopkins in 1981. There, his serendipitous discovery of aquaporins was made while pursuing the identity of the Rhesus (Rh) antigen. For a century, physiologists and biophysicists had been trying to understand the mechanism by which fluid passed across the cell's plasma membrane. Biophysical evidence indicated a limit to passive diffusion of water, suggesting the existence of another mechanism for water transport across the membrane. The putative "water channel," however, could not be identified. In 1988, while attempting to purify the 30 kDa Rh protein, Agre and colleagues began investigating a 28 kDa contaminant that they believed to be a proteolytic fragment of the Rh protein. Subsequent studies over the next 3-4 years revealed that the contaminant was a membrane-spanning oligomeric protein, unrelated to the Rh antigen, and that it was highly abundant in renal tubules and red blood cells. Still, they could not assign a function to it. The breakthrough came following a visit with his friend and former mentor John Parker. After Agre described the properties of the mysterious 28 kDa protein, Parker suggested that it might be the long-sought-after water channel. Agre and colleagues tested this idea by

  8. Peter as character in the Gospel of Matthew: complexity and inversion

    Directory of Open Access Journals (Sweden)

    João Leonel

    2014-03-01

    Full Text Available This article focuses on the apostle Peter as a character in the Gospel of Matthew.  It aims at identifying the nuances and changes of the character Peter in the Gospel. For this purpose, I take as a starting point that the gospel belongs to the literary genre of ancient Greco-Roman Biography, which presents Jesus Christ as the protagonist. The other characters are developed in relationship with him. The same is true with the Apostle Peter. The article unfolds from narrative theory, in particular the categorization of characters. I categorize, based on Erich Auerbach and Robert Alter, the features of biblical characters, developing comparisons with theories of the character in the modern novel. The analysis of the main texts from the Gospel of Matthew that portray the character Peter leads to the conclusion that its main features are complexity and inversion. They produce an overview of the involution of the character in the narrative of the Gospel of Matthew.

    2005-01-01

    A physiologically based pharmacokinetic and pharmacodynamic (PBPK/PD) models were developed for arsenic (As) in tilapia Oreochromis mossambicus from blackfoot disease area in Taiwan. The PBPK/PD model structure consisted of muscle, gill, gut wall, alimentary canal, and liver, which were interconnected by blood circulation. We integrate the target organ concentrations and dynamic response describing uptake, metabolism, and disposition of As and the associated area-under-curve (AUC)-based toxicological dynamics following an acute exposure. The model validations were compared against the field observations from real tilapia farms and previously published uptake/depuration experimental data, indicating that predicted and measured As concentrations in major organs of tilapia were in good agreement. The model was utilized to reasonably simulate and construct a dose-dependent dynamic response between mortality effect and equilibrium target organ concentrations. Model simulations suggest that tilapia gills may serve as a surrogate sensitive biomarker of short-term exposure to As. This integrated As PBPK/PD/AUC model quantitatively estimates target organ concentration and dynamic response in tilapia and is a strong framework for future waterborne metal model development and for refining a biologically-based risk assessment for exposure of aquatic species to waterborne metals under a variety of scenarios. - Integrated toxicity models can identify dynamic responses of fish to arsenic

    A physiologically based pharmacokinetic and pharmacodynamic (PBPK/PD) models were developed for arsenic (As) in tilapia Oreochromis mossambicus from blackfoot disease area in Taiwan. The PBPK/PD model structure consisted of muscle, gill, gut wall, alimentary canal, and liver, which were interconnected by blood circulation. We integrate the target organ concentrations and dynamic response describing uptake, metabolism, and disposition of As and the associated area-under-curve (AUC)-based toxicological dynamics following an acute exposure. The model validations were compared against the field observations from real tilapia farms and previously published uptake/depuration experimental data, indicating that predicted and measured As concentrations in major organs of tilapia were in good agreement. The model was utilized to reasonably simulate and construct a dose-dependent dynamic response between mortality effect and equilibrium target organ concentrations. Model simulations suggest that tilapia gills may serve as a surrogate sensitive biomarker of short-term exposure to As. This integrated As PBPK/PD/AUC model quantitatively estimates target organ concentration and dynamic response in tilapia and is a strong framework for future waterborne metal model development and for refining a biologically-based risk assessment for exposure of aquatic species to waterborne metals under a variety of scenarios. - Integrated toxicity models can identify dynamic responses of fish to arsenic.

    Peter Hochachka was an early pioneer in the field of comparative biochemistry. He passed away in 2002 after 4 decades of research in the discipline. To celebrate his contributions and to coincide with what would have been his 80th birthday, a group of his former students organized a symposium that ran as a satellite to the 2017 Canadian Society of Zoologists annual meeting in Winnipeg, Manitoba (Canada). This Special Issue of CBP brings together manuscripts from symposium attendees and other authors who recognize the role Peter played in the evolution of the discipline. In this article, the symposium organizers and guest editors look back on his career, celebrating his many contributions to research, acknowledging his role in training of generations of graduate students and post-doctoral fellows in comparative biochemistry and physiology.

  17. [Questions on the first operation with ethyl ether as anaesthetic by Dr. Peter Parker].

    Ethyl ether was the first accepted effective general anaesthetic. It was introduced into China by an America missionary, Dr. Peter Parker. This was one of the historical events of medical communication between China and the West. In the records of the first operation with ether, however, Dr. Parker unusually omitted the patient's medical record number and the date of the operation, while those of other operations with ether anesthetics were all available. This was very unusual for a doctor like Peter Parker who always recorded every important case in detail in the hospital reports. It seems that he deliberately rather than carelessly omitted the information for some reasons. Based on the analysis of Parker's reports, a conclusion is made that the anesthetic effect of the case was actually ineffective. Furthermore, possible answers to this are outlined and question by discussion based on the situation that Parker faced in the late Qing era.

    The reliable fuel element behavior during the complete fuel cycle is one of the fundamental prerequisites of a safe and efficient nuclear power plant operation. The fuel element behavior with respect to pressure drop and vibration impact cannot be simulated by means of fluid-structure interaction codes. Therefore it is necessary to perform tests using fuel element mock-ups (1:1). AREVA NP has constructed the test facility PETER (PWR fuel element tests in Erlangen) loop. The modular construction allows maximum flexibility for any type of fuel elements. Modern measuring instrumentation for flow, pressure and vibration characterization allows the analysis of cause and consequences of thermal hydraulic phenomena. PETER loop is the standard test facility for the qualification of dynamic fuel element behavior in flowing fluid and is used for failure mode analysis.

    2018-03-17

    Idiopathic inflammatory myopathy (IIM) classification criteria have been a subject of debate for many decades. Despite several limitations, the Bohan and Peter criteria are still widely used. The aim of this review is to discuss the evolution of IIM classification criteria. New IIM classification criteria are periodically proposed. The discovery of myositis-specific and myositis-associated autoantibodies led to the development of clinico-serological criteria, while in-depth description of IIM morphological features improved histopathology-based criteria. The long-awaited European League Against Rheumatism and American College of Rheumatology (EULAR/ACR) IIM classification criteria were recently published. The Bohan and Peter criteria are outdated and validated classification criteria are necessary to improve research in IIM. The new EULAR/ACR IIM classification criteria are thus a definite improvement and an important step forward in the field.

    Full Text Available I was delighted to be offered the chance to review this book because, although Professor Peters published Learning and Teaching in Distance Education: Pedagogical analyses and interpretations in an international perspective, in 1998, I hoped that this new volume would provide a new and different perspective on the most recent developments in distance education and in the role which Professor Peters has played in them. The subtitle of the new book, “New Trends and Challenges” seemed to justify my sense of anticipation. And to some extent the book does live up to expectations; it draws upon first-hand experience of the author as an online tutor who is clearly excited by the potential benefits of new technology for the teacher and, most importantly the learner.

    Full Text Available In the summer of 1982, Hans-Peter Schultze and Gloria Arratia were invited to a small museum located on a fossiliferous site of the Devonian Escuminac Formation in Miguasha, Quebec, eastern Canada, Hans-Peter was to work with Marius Arsenault, the director of the Miguasha Museum, on the skull of the elpistostegalid Elpistostege watsoni, a species closely related to basal tetrapod. In addition, he went through the collections to describe and measure numerous juvenile specimens of the osteolepiform. Eusthenopteran foordi. As expected, there two projects turned out to be important contributions in lower vertebrate paleontology and systematics: one on the origin of tetrapods (1985, and the second one on growth patterns of a Late Devonian fish (1984. During his visit to Miguasha, Hans-Peter also spent time digging for fossils and drawing numerous specimens in the collection. In addition, in order to help the personnel of the museum to identify some of the Escuminac fished, he created an identification key based on the gross morphology of the scales. For a small group of undergraduate students, hired at the museum during the summer as naturalists, it was a unique opportunity to discuss paleontology with a leading researcher. We were amazed by his willingness to talk to us, even if then most of us only spoke French! For the first time, we were exposed to Hennigian methodology and its usage in vertebrate paleontology during and evening lecture that Hans-Peter prepared for us. His lecture was delightful; it was an intensive course in lower vertebrate anatomy, and an intellectual journey among the philosophers Karl Marx and Karl Popper, the entomologists Willy Hennig and Lars Brundin, and "The Band of Four" (Rosen et al., 1981. It was for most of us our first exposure to science, as it should be done. We were all impressed by his knowledge and above all by his simplicity and friendliness. Two years later I started my Ph.D. at The University of Kansas

    Branchial Na(+)-K(+)-ATPase (NKA) activity has been suggested as a promising biomarker for assessing metal stress in aquatic organisms. However, studies that systematically show the effectiveness of using NKA activity to detect metal exposure and toxicity at the individual level are limited. In this study, we aimed to determine whether branchial NKA activity mechanistically responds to the accumulation of waterborne copper (Cu) and accounts for observed toxicity over time under environmentally-relevant and aquafarming Cu exposure levels (0.2, 1 and 2 mg L(-1)). Temporal trends in Cu accumulation and the corresponding responses of branchial NKA activity resulting from Cu exposure were investigated in laboratory experiments conducted on juvenile tilapia (Oreochromis mossambicus), a freshwater teleost that shows potential as a bioindicator of real-time and historical metal pollution. We used the process-based damage assessment model (DAM) to inspect the time course of Cu toxicity by integrating the compensation process between Cu-induced inhibition and repair of branchial NKA activity. NKA activity acted as a sensitive biomarker for Cu exposure and accumulation in tilapia, which showed induced impairment of osmoregulation and lethality when they were exposed to environmentally relevant levels (0.2 mg L(-1)), but not to higher exposure levels (1 and 2 mg L(-1)) in aquaculture farms or contaminated aquatic ecosystems. This study highlights the benefits and limitations of using branchial NKA activity as a sensitive biomarker to assess the health status of a fish population and its ecosystem.

    Full Text Available Shrimp head meal (SHM was used to replace fish meal as a protein source in practical diets for sexreversed red tilapia (Oreochromis niloticus x O. mossambicus at 0, 25, 50, 75 and 100% of fish meal protein or 0, 6.92, 13.84, 20.76 and 27.68% by weight of diet respectively. Catfish feed that contained protein content 37.22±0.10% was included as a reference diet. The experimental diets were fed to the fish with mean initial weight of 3.13±0.05 g for 8 weeks in 70 l aquaria. The results showed that weight gain and specific growth rate of fish fed 50% of fishmeal protein replacement or diet 3 was not significant by different from those of fish on control diet (p>0.05. The data of feed intake, feed conversion ratio and productive protein value of fish fed diet 3 were equal to those fed control diet (p>0.05. The lowest growth rate and feed efficiency showed on fish fed 100% of fishmeal protein replacement. The production cost of fish fed diet 3 was equal to those fed the control diet and the reference diet (p>0.05. Total carotenoid content in fish skin was significantly highest (p<0.05 in fish fed 100% of fishmeal protein replacement diet. The result indicates that the use of SHM at the level of 50% replacement or 13.84% by weight of diet is a potential protein source in sex-reversed red tilapia diet.

  4. Microtubule-dependent changes in morphology and localization of chloride transport proteins in gill mitochondria-rich cells of the tilapia, Oreochromis mossambicus.

    The tilapia (Oreochromis mossambicus) is a euryhaline fish exhibiting adaptive changes in cell size, phenotype, and ionoregulatory functions upon salinity challenge. Na(+) /Cl(-) cotransporter (NCC) and Na(+) /K(+) /2Cl(-) cotransporter (NKCC) are localized in the apical and basolateral membranes of mitochondria-rich (MR) cells of the gills. These cells are responsible for chloride absorption (NCC) and secretion (NKCC), respectively, thus, the switch of gill NCC and NKCC expression is a crucial regulatory mechanism for salinity adaptation in tilapia. However, little is known about the interaction of cytoskeleton and these adaptive changes. In this study, we examined the time-course of changes in the localization of NKCC/NCC in the gills of tilapia transferred from fresh water (FW) to brackish water (20‰) and from seawater (SW; 35‰) to FW. The results showed that basolateral NKCC disappeared and NCC was expressed in the apical membrane of MR cells. To further clarify the process of these adaptive changes, colchicine, a specific inhibitor of microtubule-dependent cellular regulating processes was used. SW-acclimated tilapia were transferred to SW, FW, and FW with colchicine (colchicine-FW) for 96 h. Compared with the FW-treatment group, in the MR cells of colchicine-FW-treatment group, (1) the average size was significantly larger, (2) only wavy-convex-subtype apical surfaces were found, and (3) the basolateral (cytoplasmic) NKCC signals were still exhibited. Taken together, our results suggest that changes in size, phenotype, as well as the expression of NCC and NKCC cotransporters of MR cells in the tilapia are microtubule-dependent. J.

    2015-08-01

    Full Text Available As the first specialist in children's literature to be appointed Head Professor at a British university (The Cardiff University, when Peter Hunt chose children’s and youth literature as his PhD theme, he was told by his advisor that it was not a seriously enough subject. During the 1980s, there were no literary critics in Britain who focused on children’s and youth books analysis. Since then, Peter Hunt is devoted to thinking children's literature by a critical and theoretical bias. Thus, this paper aims to study the theoretical and critical issues raised by Peter Hunt in order to extract a specific theory of children's literature. In proposing to study children's literature by a theoretical bias instead of by a historical, cultural or emotional one, the English researcher is concerned with issues such as the concept of the book as an object, the notion of reader and reading (how do children construct meaning?, and especially the children's literature definition. These issues are raised into the broadest context of the Twentieth Century literary theory, making them more comprehensive and productive.

    Full Text Available On 22nd August 2016, the fields of molecular neurobiology and endocrinology lost one of their pioneers and true giants, Peter Seeburg, who died aged 72, a day after his birthday. His funeral ceremony took place in Heidelberg where he had worked since 1988, first as a professor at the University of Heidelberg (ZMBH and then since 1996 as a director of the Max Plank Institute (Dept. of Molecular Neurobiology. Many of Peter’s former colleagues, students and postdocs came together with his family members to celebrate his life. Touching eulogies were given by no less than two Nobel prize winners: the physiologist Bert Sakmann, who collaborated with Peter for many years, and the developmental biologist Christiane Nüsslein-Vollhard, who was a friend and fellow PhD student with Peter. His professional contemporary, Heinrich Betz, gave a warm and endearing assessment of Peter’s contributions to the field of molecular neurobiology. One of Peter’s sons, Daniel P. Seeburg, now a neuroradiologist in the USA, and biotechnologist Karoly Nikolics, one of Peter’s friends from the days of Genentech, both emotionally summed up the warm and intense character of the man that many of his former students and postdocs knew.

    Beatriz FERNÁNDEZ HERRERO

    2009-11-01

    Full Text Available 1 For his writer, it is not possible to establish a split between reason and passion, since the affectionate aspects of morals are closely linked to the use or reason: one's own reason of assumed moral concepts forms an affectionate reply to other people in society, defined as social feeling or altruism.2 As far as the theme of contents, Peters establishes his proposal by replying to the following questions: A. WHY WORRY ABOUT THE CONTENTS? The author gives two types of reason: social reason: not all adults évolue towards superior states, many remain in the conventional state, in which it is essential to possess moral contents by which to be guided. Individual reason: learning of the contents is a pre-requisite to the application of rules in a autonomous manner. B. WHAT TYPE OF CONTENTS MUST BE TAUGTH? In reply. Peters elaborates a list of «basic rules», justifiable under any social situation, which along whith principles will constitute the contents of moral education, since according to the author, they are appropriate for whatever form social life the individuals could find. C. How SHOULD THE CONTENTS BE TAUGHT? Peters answers this in a blunt manner: in watever way that may contribute to the children learning rules, taking care not to dull their capacity for developing an independent attitude oppossing them. And as yet the techniques of cognitive stimulation cannot be used whith small children, in the preconventional and conventional states, the author believes that one must employ some form of «instruction». In short, it can be said that the legitimation of Peters' proposal centres on his consideration of morales as actions, which implies the fact that the child is an agent before being a conscious agent, which allows him to express a series of interrogatives as a way of justification of his support of the teaching in early moral education, since his objective must be not so much the development of «forms» and «models» of reasoning

    Acid mine drainage (AMD) is a global environmental concern due to detrimental impacts on river ecosystems. Little is however known regarding the biological impacts of neutralized AMD on aquatic vertebrates despite excessive discharge into watercourses. The aim of this investigation was to evaluate the endocrine modulatory potential of neutralized AMD, using molecular biomarkers in the teleost fish Oreochromis mossambicus in exposure studies. Surface water was collected from six locations downstream of a high density sludge (HDS) AMD treatment plant and a reference site unimpacted by AMD. The concentrations of 28 elements, including 22 metals, were quantified in the exposure water in order to identify potential links to altered gene expression. Relatively high concentrations of manganese (~ 10mg/l), nickel (~ 0.1mg/l) and cobalt (~ 0.03 mg/l) were detected downstream of the HDS plant. The expression of thyroid receptor-α (trα), trβ, androgen receptor-1 (ar1), ar2, glucocorticoid receptor-1 (gr1), gr2, mineralocorticoid receptor (mr) and aromatase (cyp19a1b) was quantified in juvenile fish after 48 h exposure. Slight but significant changes were observed in the expression of gr1 and mr in fish exposed to water collected directly downstream of the HDS plant, consisting of approximately 95 percent neutralized AMD. The most pronounced alterations in gene expression (i.e. trα, trβ, gr1, gr2, ar1 and mr) was associated with water collected further downstream at a location with no other apparent contamination vectors apart from the neutralized AMD. The altered gene expression associated with the "downstream" locality coincided with higher concentrations of certain metals relative to the locality adjacent to the HDS plant which may indicate a causative link. The current study provides evidence of endocrine disruptive activity associated with neutralized AMD contamination in regard to alterations in the expression of key genes linked to the thyroid, interrenal and

    The important role played by medical services in the preaching of the Gospel in China was undeniable. Anglo-American missionaries entered Canton in the early 18th century and introduced modern Western medicine to China. Reverend Dr Peter Parker, founder of medical missionaries to China, was more than that, far more advanced than his predecessors including Drs Pearson, Livingstone and Colledge. He was an enthusiastic missionary of exceptional ability and vigour as witnessed his labours at the Canton Ophthalmic Hospital. His 20 years in the medical field unexpectedly paved the way for his future career as a diplomat in the American Legation. © © IMechE 2014.

    The article investigates the way in which Peter Mittelstaedt has been contributing to the philosophy of physics for half a century. It is shown that he pursues a path between rationalism and empiricism in the sense of Erhard Scheibe’s philosophy of the physicists. Starting from Kant’s a priori he gives a rational reconstruction of the conceptual revolutions of 20th century physics. The central topic of his philosophy of physics is the quest for semantic self-consistency, which for quantum mechanics is a hard nut to crack.

    Full Text Available The punk movement is an example of peripheral culture that currently influences the dominant culture. This article aims to point out what were the changes and the innovations that the punk graphic design had to struggle to adapt itself to the series Peter Punk, exhibited by Disney XD channel. Through literature review and analysis of images, it is possible to conclude that the show’s graphic design absorbed the punk style with other influences, but without the spontaneity of punk.

    The evolution of individual and total contents of capsaicinoids present in Peter peppers (Capsicum annuum var. annuum) at different ripening stages has been studied. Plants were grown in a glasshouse and the new peppers were marked in a temporal space of ten days. The extraction of capsaicinoids was performed by ultrasound-assisted extraction with MeOH. The capsaicinoids nordihydrocapsaicin (n-DHC), capsaicin, dihydrocapsaicin, homocapsaicin, and homodihydrocapsaicin were analyzed by ultraperformance liquid chromatography (UHPLC)-fluorescence and identified by UHPLC-Q-ToF-MS. The results indicate that the total capsaicinoids increase in a linear manner from the first point of harvest at ten days (0.283 mg/g FW) up to 90 days, at which point they reach a concentration of 1.301 mg/g FW. The evolution as a percentage of the individual capsaicinoids showed the initial predominance of capsaicin, dihydrocapsaicin, and n-DHC. Dihydrocapsaicin was the major capsaicinoid up to day 50 of maturation. After 50 days, capsaicin became the major capsaicinoid as the concentration of dihydrocapsaicin fell slightly. The time of harvest of Peter pepper based on the total capsaicinoids content should be performed as late as possible. In any case, harvesting should be performed before overripening of the fruit is observed. © 2016 Wiley-VHCA AG, Zürich.

    Full Text Available Considered today as anonymous and attributed in a 1925 document to Gaspar de Crayer, the painting at Nivelles reveals the stylistic features of Peter Thijs: composition, models, handling and color are comparable to other works by his hand. As usual, Thijs has recourse to the paintings of Van Dyck, while eluding the more habitual depictions of this episode from the life of Saint Dominic, fervor for whom grew in Antwerp during the first half of the 17th century, due promotion by Dominicans and Jesuits.

    Tenida en la actualidad como anónima, y atribuida a Gaspar de Crayer en documentos de principios del siglo XX, la pintura de la Colegiata de Nivelles es comparable en composición, modelos, factura y sentido del color con otras obras de Peter Thijs. El pintor recurre, como fue su costumbre, a Van Dyck, a la vez que se distancia de las representaciones más frecuentes de este episodio de la vida de Santo Domingo, cuyo fervor creció en Amberes por impulso de dominicos y jesuitas en la primera mitad del siglo XVII.

    2014-10-01

    Full Text Available In Steven Spielberg's cinema the flight is a recurring theme. Flying scenes can be sorted into two classes: those involving a realistic flight – by aircraft – and those involving a magical flight – by supernatural powers. The realistic flight is influenced by the war stories of Spielberg's father – a radio man in U.S. Air-force during WWII – and it is featured in such films as Empire of the Sun (1987, Always (1989, and 1941 (1979. The magical flight is influenced by James M. Barries' character Peter Pan (Peter and Wendy, 1911, which is quoted directly in E.T. the Extraterrestrial (1982 and, above all, in Hook (1991, which is a sequel to Barrie's story. These two types of flying scenes are analysed as to their meanings, compared to the models that influenced them, and surveyed as to their evolution across Spielberg's films. A central case study is the episode The Mission from Amazing Stories (1985, in which the realistic and the magical flights overlap.

    Peter Lee was, until he very recently retired, a senior lecturer in the History Education Unit at the Institute of Education at the University of London. Having taught History in primary and secondary schools, Professor Lee has coordinated several research projects related to History Teaching and Learning, including CHATA (Concepts of History and Teaching Approaches a project well-known in Brazil. Several of his publications investigate the ideas that children and teenagers have over History in several books, chapters, and articles – many of these with Rosalyn Ashby as co-author.  Some of his articles have been translated to Portuguese, circulating among researchers concerned with understanding how children learn History. The questions in this interview have been elaborated so that Peter Lee’s reflections may collaborate with the development of History Teaching and History Education research in Brazil. All contact has been made via e-mail, a rather useful tool that has shortened the distance between Florianópolis and London for a few long moments between July and October 2012.

    1986-01-01

    The goal of the Performance Evaluation Tests for Environmental Research (PETER) Program was to identify a set of measures of human capabilities for use in the study of environmental and other time-course effects. 114 measures studied in the PETER Program were evaluated and categorized into four groups based upon task stability and task definition. The Recommended category contained 30 measures that clearly obtained total stabilization and had an acceptable level of reliability efficiency. The Acceptable-But-Redundant category contained 15 measures. The 37 measures in the Marginal category, which included an inordinate number of slope and other derived measures, usually had desirable features which were outweighed by faults. The 32 measures in the Unacceptable category had either differential instability or weak reliability efficiency. It is our opinion that the 30 measures in the Recommended category should be given first consideration for environmental research applications. Further, it is recommended that information pertaining to preexperimental practice requirements and stabilized reliabilities should be utilized in repeated-measures environmental studies.

    Full Text Available El análisis del folclore y las tradiciones de una sociedad es una herramienta indispensable para dibujar y comprender un lugar y una época. En el ámbito lúdico, los juegos de la población tienen que permitir estudiar diferentes aspectos sociales tales como la tipología de estas prácticas y sus participantes, su simbolización o la situación económica de un pueblo y una clase social. El objeto de estudio del presente artículo es la obra pictórica de Peter Brueghel, Juegos de niños (1560. Concretamente, se analizan las diferentes prácticas lúdicas en función de su carácter motriz, de su lógica interna y de la utilización de algún instrumento. La metodología se ha basado el análisis estadístico de los juegos que aparecen en el grabado y en el tratamiento de las principales fuentes textuales que interpretan el cuadro y lo relacionan con la sociedad de la época. Los resultados se relacionan y reafirman los estudios históricos de la época en los cuales se destaca la poca intervención-control por parte del adulto y unas prácticas lúdicas, mayoritariamente de bajo nivel socio-cognitivo-motriz. Se concluye que la obra permite describir la situación de los juegos en su época, vista desde la óptica del pintor, lo que tiene que permitir aplicar estas prácticas al siglo XXI, comparándolas y relacionándolas con los juegos de hoy en día.

    2014-04-01

    Peter Becker was a German neurologist who helped classify the muscular dystrophies, and described Becker muscular dystrophy and Becker myotonia. His involvement in National Socialism began in 1933, when he was compelled by his peers to join the SA (brown shirts). He later joined the Nazi party, the Nazi Doctors Association, and the Nazi Lecturers' Association. He renewed his SA membership to maintain his position at a genetics institute. Colleagues stated postwar that he was not an active Nazi, and he was de-Nazified in 1947, able to continue his career. Later, Becker admitted to most, but not all, of his Nazi memberships in his autobiography, and wrote 2 books exploring the origins of Nazism and racial hygiene. The "neurologic court of opinion" must weigh in on how we should best remember Becker, and at the very least, we as neurologists must learn the dangers of career opportunism at any cost.

    This video clip is an interview with Dr. Peter Cavanaugh, principal investigator for the FOOT experiment. He explains the reasoning behind the experiment and shows some video clips of the FOOT experiment being calibrated and conducted in orbit. The heart of the FOOT experiment is an instrumented suit called the Lower Extremity Monitoring Suit (LEMS). This customized garment is a pair of Lycra cycling tights incorporating 20 carefully placed sensors and the associated wiring control units, and amplifiers. LEMS enables the electrical activity of the muscles, the angular motions of the hip, knee, and ankle joints, and the force under both feet to be measured continuously. Measurements are also made on the arm muscles. Information from the sensors can be recorded up to 14 hours on a small, wearable computer.

    2015-02-01

    As President Jimmy Carter's advisor for health issues, Peter Bourne promoted a rational and comprehensive drug strategy that combined new supply-side efforts to prevent drug use with previously established demand-side addiction treatment programs. Using a public health ethic that allowed the impact of substances on overall population health to guide drug control, Bourne advocated for marijuana decriminalization as well as increased regulations for barbiturates. A hostile political climate, a series of rumors, and pressure from both drug legalizers and prohibitionists caused Bourne to resign in disgrace in 1978. We argue that Bourne's critics used his own public health framework to challenge him, describe the health critiques that contributed to Bourne's resignation, and present the story of his departure as a cautionary tale for today's drug policy reformers.

  1. The Learning Curve in neurofeedback of Peter Van Deusen: A review article

    Directory of Open Access Journals (Sweden)

    Valdenilson Ribeiro Ribas

    Full Text Available ABSTRACT The Learning Curve (TLC in neurofeedback concept emerged after Peter Van Deusen compiled the results of articles on the expected electrical activity of the brain. This concept was subsequently tested on patients at four clinics in Atlanta between 1994 and 2001. The aim of this paper was to report the historical aspects of TLC. Articles published on the electronic databases MEDLINE/PubMed and Web of Science were reviewed. During patient evaluation, TLC investigates categories called disconnected, hot temporal lobes, reversal of alpha and beta waves, blocking, locking, and filtering or processing. This enables neuroscientists to use their training designs and, by means of behavioral psychology, to work on neuroregulation, as self-regulation for patients. TLC shows the relationships between electrical, mental and behavioral activity in patients. It also identifies details of patterns that can assist physicians in their choice of treatment.

The drawing, until now known only through the black and white photograph, could be thoroughly analysed for the first time. In the context of information thus obtained, the historical context of creating the sketch transpired as an equally important matter, including the hypothetical role that may have been played in its creation by Nicolas-Claude Fabri de Peiresc.

  5. Sir Peter Medawar: science, creativity and the popularization of Karl Popper

    Science.gov (United States)

    Calver, Neil

    2013-01-01

    Sir Peter Medawar was respected by scientists and literati alike. It was perhaps not surprising, then, that he would choose to involve himself in the ‘two cultures’ debate of 1959 and beyond. The focus of his intervention was the philosophy of Sir Karl Popper. However, Medawar's Popper was not the guru of falsification familiar from philosophy textbooks. Medawar's distinctive interpretation of Popper treated him instead as the source of insights into the role of creativity and imagination in scientific inquiry. This paper traces the context for Medawar's adoption of Popperian philosophy, together with its application before the debate. It then examines, within the context of the debate itself, the way in which Medawar attempted to reconcile scientific inquiry with literary practice. Medawar became increasingly convinced that not only was induction epistemologically unsound, but it was also damaging to the public role of the scientist. His construction of Popperianism would, he envisaged, provide a worthy alternative for scientists’ self-image.

    Tilapia mossambica Peters larvae 10 days after hatching were X-irradiated at 350 R, and the number of germinative cells at different stages of development was followed. In the control, 10-day larvae possessed primordial germ cells and gonia; 15-day larvae had mostly gonia; in 20-day larvae some gonia were entering early prophase of meiosis; 25-day larvae possessed gonia and early meiotic prophase oocytes; and 30-day larvae had oogonia, oocytes at early prophase and at the previtellogenesis stage. After the irradiation, 13- and 14-day larvae showed some mitotic disturbances; however the mass death of germ cells was observed after their entering the pachytene stage in fishes 25 days old

  8. Yes! There is an ethics of care: an answer for Peter Allmark.

    Science.gov (United States)

    Bradshaw, A

    1996-01-01

    This paper is a response to Peter Allmark's thesis that 'there can be no "caring" ethics'. It argues that the current preoccupation in nursing to define an ethics of care is a direct result of breaking nursing tradition. Subsequent attempts to find a moral basis for care, whether from subjective experimental perspectives such as described by Noddings, or from rational and detached approaches derived from Kant, are inevitably flawed. Writers may still implicitly presuppose a concept of care drawn from the Judaeo-Christian tradition but without explicit recourse to its moral basis nursing is left rudderless and potentially without purpose. The very concept of 'care' cut off from its roots becomes a meaningless term without either normative or descriptive content. PMID:8932719

    Asbestos crystallizes within rock formations undergoing intense deformation characterized by folding, faulting, shearing, and dilation. Some of these conditions have prevailed during formation of the taconite iron ore deposits in the eastern Mesabi Iron Range of Minnesota. This range includes the Peter Mitchell Taconite Mine at Babbitt, Minnesota. The mine pit is over 8 miles long, up to 1 mile wide. Fifty three samples were collected from 30 sites within areas of the pit where faulting, shearing and folding occur and where fibrous minerals might occur. Eight samples from seven collecting sites contain significant amounts of ferroactinolite amphibole that is partially to completely altered to fibrous ferroactinolite. Two samples from two other sites contain ferroactinolite degraded to ropy masses of fibers consisting mostly of ferrian sepiolite as defined by X-ray diffraction and TEM and SEM X-ray spectral analysis. Samples from five other sites contain unaltered amphiboles, however some of these samples also contain a very small number of fiber bundles composed of mixtures of grunerite, ferroactinolite, and ferrian sepiolite. It is proposed that the alteration of the amphiboles was caused by reaction with water-rich acidic fluids that moved through the mine faults and shear zones. The fibrous amphiboles and ferrian sepiolite collected at the Peter Mitchell Mine composes a tiny fraction of one percent of the total rock mass of this taconite deposit; an even a smaller amount of these mineral fragments enter the ambient air during mining and milling. These fibrous minerals thus do not present a significant health hazard to the miners nor to those non-occupationally exposed. No asbestos of any type was found in the mine pit.

  11. Simulation of ground-water flow in the St. Peter aquifer in an area contaminated by coal-tar derivatives, St. Louis Park, Minnesota. Water Resources Investigation

    1990-01-01

    A model constructed to simulate ground-water flow in part of the Prairie du Chien-Jordan and St. Peter aquifers, St. Louis Park, Minnesota, was used to test hypotheses about the movement of ground water contaminated with coal-tar derivatives and to simulate alternatives for reducing the downgradient movement of contamination in the St. Peter aquifer. The model, constructed for a previous study, was applied to simulate the effects of current ground-water withdrawals on the potentiometric surface of the St. Peter aquifer. Model simulations predict that the multiaquifer wells have the potential to limit downgradient migration of contaminants in the St. Peter aquifer caused by cones of depression created around the multiaquifer wells. Differences in vertical leakage to the St. Peter aquifer may exist in areas of bedrock valleys. Model simulations indicate that these differences are not likely to affect significantly the general patterns of ground-water flow

    Full Text Available This article raises the question of the Old Russian sources of Alexander Pushkin’s novel The Captain’s Daughter and presents an attempt to identify the traditions of Ermolay-Erazmus’s The Tale of Peter and Fevronia in it. The main purpose of the research was to identify the parallelism between Pushkin’s novel and The Tale at the imaginative, narrative and thematic levels. Therefore, it was based on application of the comparative method. The main characters of both the books are compared in succession: Prince Peter and Peter Grinyov first, and then Fevronia and Masha Mironova. The results of the analysis lead to the conclusion that the male images reflect the spiritual evolution from being self-willed to obtaining Christian humility, and the key moment of the characters’ spiritual evolution is the meeting with wise virgins, etc. As far as the female images are concerned, the key parallel between them is the praise of their wisdom at the end of both stories. Thus, the material of the research enables us to speak about the traditions of The Tale of Peter and Fevronia being preserved in Pushkin’s last novel.

    Bohan and Peter criteria are widely used for the diagnosis of idiopathic inflammatory myopathies (IIMs). Recently, European Neuromuscular Center (ENMC) formulated criteria to identify subgroups of IIMs. To compare the two diagnostic criteria in adult IIMs. This was a retrospective review of case records of histologically confirmed IIMs in adults between January 2014 and May 2015. Both the Bohan and Peter, and ENMC 2004 criteria were applied in the same group of patients to subgroup the IIMs. Muscle biopsy was evaluated in all the four domains: muscle fiber, inflammatory, connective tissue, and vascular, with the basic panel of histological stains. Sporadic inclusion body myositis (s-IBM) was diagnosed using ENMC IBM diagnostic research criteria 2011. During the study period, 69 patients fulfilled the ENMC criteria for IIMs including 16 patients with s-IBM. The subgrouping as per the ENMC criteria (53) was: dermatomyositis (DM) in 30; polymyositis (PM) in 2; immune-mediated necrotizing myopathy (IMNM) in 9; and nonspecific myositis (NM) in 12 patients, whereas subgrouping by the Bohan and Peter criteria was DM in 9 and PM with and without connective tissue disease (CTD) in 26 patients only. There was underdiagnosis of DM, as perifascicular atrophy is not recognized as a diagnostic histological feature, and overdiagnosis of PM with and without CTD due to poor characterization of histological features in PM by the Bohan and Peter criteria. Systematic evaluation of muscle biopsy according to the ENMC criteria with basic panel of histochemical stains improved the diagnostic yield of IIM significantly when compared to the Bohan and Peter criteria.

  4. Utilization of the St. Peter Sandstone in the Illinois Basin for CO2 Sequestration

    Energy Technology Data Exchange (ETDEWEB)

    Will, Robert; Smith, Valerie; Leetaru, Hannes

    2014-09-30

    This project is part of a larger project co-funded by the United States Department of Energy (US DOE) under cooperative agreement DE-FE0002068 from 12/08/2009 through 9/31/2014. The study is to evaluate the potential of formations within the Cambro-Ordovician strata above the Mt. Simon Sandstone as potential targets for carbon dioxide (CO2) sequestration in the Illinois and Michigan Basins. This report evaluates the potential injectivity of the Ordovician St. Peter Sandstone. The evaluation of this formation was accomplished using wireline data, core data, pressure data, and seismic data acquired through funding in this project as well as existing data from two additional, separately funded projects: the US DOE funded Illinois Basin – Decatur Project (IBDP) being conducted by the Midwest Geological Sequestration Consortium (MGSC) in Macon County, Illinois, and the Illinois Industrial Carbon Capture and Sequestration (ICCS) Project funded through the American Recovery and Reinvestment Act (ARRA), which received a phase two award from DOE. This study addresses the question of whether or not the St. Peter Sandstone may serve as a suitable target for CO2 sequestration at locations within the Illinois Basin where it lies at greater depths (below the underground source of drinking water (USDW)) than at the IBDP site. The work performed included numerous improvements to the existing St. Peter reservoir model created in 2010. Model size and spatial resolution were increased resulting in a 3 fold increase in the number of model cells. Seismic data was utilized to inform spatial porosity distribution and an extensive core database was used to develop porosity-permeability relationships. The analysis involved a Base Model representative of the St. Peter at “in-situ” conditions, followed by the creation of two hypothetical models at in-situ + 1,000 feet (ft.) (300 m) and in-situ + 2,000 ft. (600 m) depths through systematic depthdependent adjustment of the Base Model

  10. Personality as a Social Process: where Peter Giordano Meets Boris Parygin.

    2018-02-27

    In this paper I comment on the "Individual personality is best understood as process, not structure: A Confucian-inspired perspective" article by Peter Giordano (Culture & Psychology, 23(4), 502-518 (2017)), which addresses the question of how to comprehend a personality which is continuously changing and varying with changes in social contexts and situations. The issue which Giordano turns up I believe to be of great importance and topicality in the quickly changing globalizing contemporary world. Giordano's paper highlights an important problem in the development of contemporary personality psychology, but much remains to be clarified concerning his process-centric model. I introduce the theory of Boris Parygin, which can make a contribution to the discussion of personality as a process. Parygin's theory addresses the same issues that Giordano focuses on: human personality exists and develops in the context of social situation. Parygin's theoretical model of personality involves two personality schemas: a "static" one and a "dynamic" one. The "structure" and the "process" -centered approaches are joint here to complement each other. Personality life-span development, formation of personality structures, is considered as a process of interaction and dialectical confrontation with the social environment, in the course of which the personality, originally engendered by social factors, builds up its autonomy and realizes its unique individual spiritual potential.

  11. Principles of plastic surgery portrayed by the professional life of Dr John Peter Mettauer.

    Science.gov (United States)

    Avashia, Yash J; Thaller, Seth R

    2011-11-01

    Regarded as "America's first plastic surgeon," Dr John Peter Mettauer's professional life displays 3 fundamental keystones of plastic surgery: education, innovation, and practice. To fully appreciate the history of our plastic surgery, one must look beyond a purely factual recount of noteworthy actions performed decades ago. Fundamental principles that governed achievements of our predecessors remain applicable even today. Dr Mettauer thrived as a medical student under the influence of distinguished professors in medicine at the University of Pennsylvania. Later, he continued to propagate their basic tenets when he established his medical institute in 1837. Throughout his life, Dr Mettauer combined ingenuity with scientific inquiry to devise numerous unprecedented surgical techniques and instruments. He was a prolific writer and exquisitely documented his work in medical journals for the benefit of both contemporary and future surgeons. One of Dr Mettauer's momentous achievements in plastic surgery that displays his remarkable capabilities was his contributions to management of both simple and complicated cases of cleft palate. He was the first to describe relaxing lateral incisions for treating complete cleft palates and, incidentally, was the first to successfully treat this in America. He invariably replicated similar success in establishing techniques for treating a wide range of anatomic deformities. Cumulatively, Dr Mettauer's lifelong commitment and diligence have truly laid a foundation for the eventual progress and success in the field of plastic surgery.

  12. The Quantum Logical Challenge: Peter Mittelstaedt's Contributions to Logic and Philosophy of Science

    Science.gov (United States)

    Beltrametti, E.; Dalla Chiara, M. L.; Giuntini, R.

    2017-12-01

    Peter Mittelstaedt's contributions to quantum logic and to the foundational problems of quantum theory have significantly realized the most authentic spirit of the International Quantum Structures Association: an original research about hard technical problems, which are often "entangled" with the emergence of important changes in our general world-conceptions. During a time where both the logical and the physical community often showed a skeptical attitude towards Birkhoff and von Neumann's quantum logic, Mittelstaedt brought into light the deeply innovating features of a quantum logical thinking that allows us to overcome some strong and unrealistic assumptions of classical logical arguments. Later on his intense research on the unsharp approach to quantum theory and to the measurement problem stimulated the increasing interest for unsharp forms of quantum logic, creating a fruitful interaction between the work of quantum logicians and of many-valued logicians. Mittelstaedt's general views about quantum logic and quantum theory seem to be inspired by a conjecture that is today more and more confirmed: there is something universal in the quantum theoretic formalism that goes beyond the limits of microphysics, giving rise to interesting applications to a number of different fields.

  13. Earthquake Magnitude Relationships for the Saint Peter and Saint Paul Archipelago, Equatorial Atlantic

    de Melo, Guilherme W. S.; do Nascimento, Aderson F.

    2018-03-01

    We have investigated several relationships between ML, M(NEIC) and Mw for the earthquakes locally recorded in the Saint Peter and Saint Paul Archipelago (SPSPA), Equatorial Atlantic. Because we only have one station in the area, we could not derive attenuation relations for events recorded at different distances at different stations. Our approach was then to compare our ML estimates with magnitudes reported by NEIC. This approach produced acceptable results particularly for epicentral distance smaller than 100 km. For distances greater that 100 km, there is a systematic increase in the residuals probable due to the lack of station correction and our inability to accurately estimate Q. We also investigate the Mw—M(NEIC) relationship. We find that Mw estimates using S-wave produce smaller residuals when compared with both M(NEIC). Finally, we also investigate the ML—Mw relationship and observe that given the data set we have, the 1:1 holds. We believe that the use of the present methodologies provide consistent magnitude estimates between all the magnitudes investigated that could be used to better assess seismic hazard in the region.

    Full Text Available http://dx.doi.org/10.5007/1677-2954.2009v8n1p9 Peter Singer’s views on the status of animals, the sanctity of human life, and world poverty have attracted both attention and intense controversy in many Western countries, including the United States, Canada, and Germany. The reactions in France to his theories are less well-known. The purpose of this paper is to present an overview of critical responses to Singer by French academics and thinkers. How have they received Singer’s contention that we must bring nonhuman animals within the sphere of moral concern? How has his claim been received according to which we must recognize that the worth of human life varies? Do French scholars agree with his utilitarian views on abortion, euthanasia, infanticide, his defi nition of the term “person”? Finally, is he considered in France as a brilliant and groundbreaking ethicist, as a dangerous extremist, or somewhere in between

    Dendronereis spp. (Peters) (Nereididae) is a common polychaete in shrimp ponds built on intertidal land and is natural food for shrimp in traditionally managed ponds in Indonesia. White spot syndrome virus (WSSV), an important viral pathogen of the shrimp, can replicate in this polychaete (Desrina et al. 2013); therefore, it is a potential propagative vector for virus transmission. The major aim of this study was to determine whether WSSV can be transmitted from naturally infected Dendronereis spp. to specific pathogen-free (SPF) Pacific white shrimp Litopenaeus vannamei (Boone) through feeding. WSSV was detected in naturally infected Dendronereis spp. and Penaeus monodon Fabricius from a traditional shrimp pond, and the positive animals were used in the current experiment. WSSV-infected Dendronereis spp. and P. monodon in a pond had a point prevalence of 90% and 80%, respectively, as measured by PCR. WSSV was detected in the head, gills, blood and mid-body of Dendronereis spp. WSSV from naturally infected Dendronereis spp was transmitted to SPF L. vannamei and subsequently from this shrimp to new naïve-SPF L. vannamei to cause transient infection. Our findings support the contention that Dendronereis spp, upon feeding, can be a source of WSSV infection of shrimp in ponds. © 2014 John Wiley & Sons Ltd.

    Full Text Available This article investigates the role that Practical Theology can play in addressing the problem of alienation amongst the people of South Africa. The investigation is conducted from the viewpoint of the biblical concept of diakonia (service work. This concept as well as the content of Practical Theology as it is found in the first letter of Peter is investigated with the purpose of elucidating the diakonia of Practical Theology with regard to alienation. Four questions are answered in the article:� What may some of the reasons why people in South Africa experience alienation be?� What significance do the results of the most recent research into the diakon word group have for the diakonia of Practical Theology?� What insight can be gained from 1 Peter into the diakonia of Practical Theology for people who may be experiencing alienation in South Africa?� What should the diakonia of Practical Theology in the light of 1 Peter be for people who experience alienation? Intradisciplinary and/or interdisciplinary implications: This article addresses the issue of alienation. This is an issue that also falls within the research field of sociology and psychology. This article wants to make a contribution from a biblical perspective using the exegesis of a New Testament letter (1 Pt with the focus on 1 Peter 4:10 and the use of the diakon word group in the letter. The article thus also operates on the research field of New Testament Theology. The results of the exegesis are used to give guidelines for the diakonia of Practical Theology in South Africa. The article challenges the way some research in Practical Theology is done, not using the Bible as reference point, thus making the distinction between Practical Theology and sciences like sociology and psychology indistinct.

    Peter Drucker (1978) holds that managers must take responsibility for the common weal. This notion seems to contradict Milton Friedman's (1970) famous observation according to which, "the social responsibility of business is to increase its profits." As the essay demonstrates, Friedman (1970) does not deduce this claim in terms of economic reasoning. Rather, in his determination of managerial obligations, he refers to the institutions of private property and the act of contracting. He thus ev...

    Microseismic noise, also known as ambient seismic noise, are continuous vibrations mostly composed of Rayleigh waves pervasively recorded in the mili Hertz to 1 Hz frequency range. Their precise source mechanisms are under investigations and related to atmospheric perturbations and ocean gravity waves. Our purpose is to show the behavior of the microseismic noise recorded in the Saint Peter and Saint Paul Archipelago (SPSPA) with respect to wind intensity and ocean waves height in this region, between the North and South Atlantic Ocean. We have recorded both primary microseisms (PM) 0.04-0.12 Hz and the secondary microseisms (SM) 0.12-0.4 Hz during almost four years (2012-2015) and we used frequency, temporal, spatial and statistical correlation analysis to do qualitative and quantitative analysis with respect to wind speed intensity and significant wave height for the same periods. The results indicate a good correlation between the PM and the SM noise in the region particularly during the winter in the Northern Hemisphere and a poor correlation during the summer. We have also shown that probably most of the PM are generated in the SPSPA itself. We note that the intensity of SM recorded in SPSPA appears to have a seasonal behavior with the summer and winter in the Northern Hemisphere, and seems to influence the correlation between the PM and the SM, suggesting that the sources of the PM and the SM are not related to the same atmospheric event and from different places. PM generation would occur near the SPSPA whilst the SM would have distant sources towards the North Atlantic.

  4. The word “Theology” from the Presocratics to Peter Abelard: Philosophy and Science. Some Remarks

    Mauro Ferrante

    2017-02-01

    Full Text Available The purpose of this paper is to reconstruct, through the analysis of some key moments, the evolution of the term “theology” within the Western philosophical thought. Starting with the first formulation by the Presocratics, the study takes into consideration both the first attestation of the term by Plato (in the second book of the Republic and the role it plays in Aristotle’s works (Metaphysics. In its second part, the paper considers the importance of the term “theology” in the Latin world, through the study of the Augustine’s critic against the greek thinkers, which will lead to a further development in the Middle Ages. The point of arrival is Peter Abelard, who formulated a concept of “theology” conceived as a science. At first, the term was tied to a pagan conception of society and was devoid of any scientific connotation. With the advent of Christianity, it begins to take on an universalistic character connected with the concept of an absolute truth. It is here pointed out, through all of these antecedents, how, in the Middle Ages, when the “theology” became an autonomous science and responds to its own laws, how it is assumed and used as an instrument to manage both science and truth. Thanks to the contributions of the ancient philosophers, developed by medieval thinkers, it was possible to subsequently use the term “theology” also in a political sense. It also allows us to extend it to other fields than its original one. Finally, this paper wants to stress that it is necessary to first study the evolution of the concepts of terminology, because it allows us to better understand the concepts that are used in science

  5. The Petition of Peter the Great for The Orthodox Christians of Venice as Part of Russia's Foreign Policy

    Full Text Available The petition of Peter the Great for return of a taken church from the Orthodox christians of Venice is interesting in the context of the religious motives behind his domestic and foreign policy, his interaction with Catholicism, and his support of Orthodoxy in Europe and the Ottoman Empire. The charter itself is a unique document testifying to the concerns of the Russian czar for coreligionists in a Catholic country. At the same time, it is clear that in an epoch when religion was tightly intertwined with politics, such an appeal was not only part of religious but also secular politics. The goals of the Russian government in the Balkans coincide with the aspirations of the Orthodox peoples languishing under the yoke of the Turks: they had seen in Russia the liberator of the hated invaders. The natural allies of Moscow-Petersburg themselves for a long time to convince kings to stand up for the persecuted faith, and calls were heard from bishops of the Eastern Church and the authorities are dependent on the Turkish vassal principalities. Finally, the moment came. Despite the fact that Peter did not want war with the Sultan, he had to prepare for it, and for that sought to mobilize all the allies, including the Balkan Christians. The letter addressed to the Venetian Doge, actually addressed to them. Following the message the Russian government opens in Venice diplomatic agency, whose task are monitoring the political situation in Italy and the Balkans, as well as the recruitment of volunteers under the fl ag of St. Andrew. Thus, the charter-petition of Peter for the Orthodox of Venice has completely fulfi lled its task — it has become part of a policy to win sympathy of the peoples of the Balkans, and has contributed to the understanding that the Venetian government would not object to the actions of the Russian envoys in the country.

    Seasonal changes in the dissolved oxygen (DO) content in water were analyzed based on long-term observations (2006-2013) in the Eastern Bosporus Strait (Peter the Great Bay, Sea of Japan). It was found that the monthly average DO concentrations at the bottom of the strait were significantly lower in summer than the average annual long-term data. The minimum DO contents were recorded during four months, from July to October. It was shown that the DO content in water depended on changes in current directions in the strait: lower DO contents resulted from hypoxic water inflow, mostly from Amur Bay.

    Dorothy L. Sayers created in her fictional character Lord Peter Wimsey a “contrasexual” figure in her own imagination, with whom she carried on an extended dialogue over many years. C.G. Jung's concept of the contrasexual archetype, the anima (in men) or the animus (in women), can provide a very useful tool for investigating the presence of this transgendered voice within the self. Specifically in relation to Sayers and her Wimsey, Jung's theory can uncover the successful conversion of a pote...

    Full Text Available Through the study of one case in particular this article wishes to contribute to adding to the knowledge concerning the importation of printed music in Spain from 1868 to 1892. The case in point refers to the commercial relations that existed during the above period between the German Editorial, Peters, and certain Spanish editors then in business. The material in question consists of nineteen documents -sixteen letters, two order lists and a steamship dispatch certificate- addressed mostly to Peters by five editors and a Spanish musical association, all of which are currently conserved in a well known Leipzig Archive: the Sächsisches Staatsarchiv Leipzig. Reading and analyzing the said documents introduces us to subject matter which, although it has been studied before, enshrouds many unanswered questions: through what channels was foreign music introduced, what means of payment were employed and what manner of repertory was requested? The answer to these questions will give us an idea of the tastes prevalent during that period as well as the commercial outlets utilized, etc.Este artículo pretende ser una aportación al mejor conocimiento de la importación de música impresa en España entre 1868 y 1892 a través de un caso concreto: la relación comercial que existió durante el periodo mencionado entre la editorial alemana Peters y algunos de los editores españoles entonces activos.

A través de la lectura y análisis de dichos documentos nos acercamos a un fenómeno que, aunque conocido y estudiado, todavía encierra diversos interrogantes: cuáles eran las vías de suministro

    Full Text Available Musical creativity may be expressed by composers in diverse ways: sometimes they compose fully original works, which are characterized by specific features making them unique. Other times, musicians may feel a particular affinity with colleagues who lived centuries before, or identify peculiar resemblances between the time they live in, and a previous epoch, such as similar cultural climate and approach to life: in these cases, composers may author pieces which show surprising similarities with those of some predecessors. The present study compares a work of the seventeenth century, composed by Barbara Strozzi, and one composed in the 1960s by Peter Maxwell Davies, highlighting their similarities.

  13. Differential effects of cortisol and 11-deoxycorticosterone on ion transport protein mRNA levels in gills of two euryhaline teleosts, Mozambique tilapia (Oreochromis mossambicus) and striped bass (Morone saxatilis).

    2011-04-01

    The role of cortisol as the only corticosteroid in fish osmoregulation has recently been challenged with the discovery of a mineralocorticoid-like hormone, 11-deoxycorticosterone (DOC), and necessitates new studies of the endocrinology of osmoregulation in fish. Using an in vitro gill explant incubation approach, DOC-mediated regulation of selected osmoregulatory target genes in the gill was investigated and compared with that of cortisol in two euryhaline teleosts, Mozambique tilapia (Oreochromis mossambicus) and striped bass (Morone saxatilis). The effects were tested in gills from both fresh water (FW)- and seawater (SW)-acclimated fish. Both cortisol and DOC caused an up-regulation of the Na(+),K(+)-ATPase α1 subunit in SW-acclimated tilapia but had no effect in FW-acclimated fish. Cortisol conferred an increase in Na(+),K(+),2Cl(-) cotransporter (NKCC) isoform 1a transcript levels in FW- and SW-acclimated tilapia, whereas DOC had a stimulatory effect only in SW-acclimated fish. Cortisol had no effect on NKCC isoform 1b mRNA levels at both salinities, while DOC stimulated this isoform in SW-acclimated fish. In striped bass, cortisol conferred an up-regulation of Na(+),K(+)-ATPase α1 and NKCC transcript levels in FW- and SW-acclimated fish, whereas DOC resulted in down-regulation of these transcripts in FW-acclimated fish. It was also found that both corticosteroids may rapidly (30 min) alter the mitogen-activated protein kinase signalling pathway in gill, inducing phosphorylation of extracellular signal-regulated kinase 1 (ERK1) and ERK2 in a salinity-dependent manner. The study shows a disparate organisation of corticosteroid signalling mechanisms involved in ion regulation in the two species and adds new evidence to a role of DOC as a mineralocorticoid hormone in teleosts.

  14. Functional classification of mitochondrion-rich cells in euryhaline Mozambique tilapia (Oreochromis mossambicus) embryos, by means of triple immunofluorescence staining for Na+/K+-ATPase, Na +/K+/2Cl- cotransporter and CFTR anion channel

    Mozambique tilapia Oreochromis mossambicus embryos were transferred from freshwater to seawater and vice versa, and short-term changes in the localization of three major ion transport proteins, Na+/K +-ATPase, Na+/K+/2Cl- cotransporter (NKCC) and cystic fibrosis transmembrane conductance regulator (CFTR) were examined within mitochondrion-rich cells (MRCs) in the embryonic yolk-sac membrane. Triple-color immunofluorescence staining allowed us to classify MRCs into four types: type I, showing only basolateral Na+/K +-ATPase staining; type II, basolateral Na+/K +-ATPase and apical NKCC; type III, basolateral Na+/K +-ATPase and basolateral NKCC; type IV, basolateral Na +/K+-ATPase, basolateral NKCC and apical CFTR. In freshwater, type-I, type-II and type-III cells were observed. Following transfer from freshwater to seawater, type-IV cells appeared at 12 h and showed a remarkable increase in number between 24 h and 48 h, whereas type-III cells disappeared. When transferred from seawater back to freshwater, type-IV cells decreased and disappeared at 48 h, type-III cells increased, and type-II cells, which were not found in seawater, appeared at 12 h and increased in number thereafter. Type-I cells existed consistently irrespective of salinity changes. These results suggest that type I is an immature MRC, type II is a freshwater-type ion absorptive cell, type III is a dormant type-IV cell and/or an ion absorptive cell (with a different mechanism from type II), and type IV is a seawater-type ion secretory cell. The intracellular localization of the three ion transport proteins in type-IV cells is completely consistent with a widely accepted model for ion secretion by MRCs. A new model for ion absorption is proposed based on type-II cells possessing apical NKCC.

Advertising has been influencing us pervasively in our daily life. It is not only the means of commodity marketing, but also the transmitter of culture. To the sellers, an effec-tive advertising involves not only what to say but also how to say. While to the translators, what they concern most is how to convey the information appropriately and effectively. Therefore, it is necessary to study English advertising texts (EAT) and their translation strategies.

  17. Peter Bourne’s Drug Policy and the Perils of a Public Health Ethic, 1976–1978

    Science.gov (United States)

    Dufton, Emily

    2015-01-01

    As President Jimmy Carter’s advisor for health issues, Peter Bourne promoted a rational and comprehensive drug strategy that combined new supply-side efforts to prevent drug use with previously established demand-side addiction treatment programs. Using a public health ethic that allowed the impact of substances on overall population health to guide drug control, Bourne advocated for marijuana decriminalization as well as increased regulations for barbiturates. A hostile political climate, a series of rumors, and pressure from both drug legalizers and prohibitionists caused Bourne to resign in disgrace in 1978. We argue that Bourne’s critics used his own public health framework to challenge him, describe the health critiques that contributed to Bourne’s resignation, and present the story of his departure as a cautionary tale for today’s drug policy reformers.

    2012-02-01

    A Child Analysis with Anna Freud, a collection of Anna Freud's detailed case notes of her treatment of the young Peter Heller between 1929 and 1932, was first published in English in 1990. Not only does this work give us direct access to Anna Freud's ways of thinking and working at a crucial period in the early history of child analysis; it is also one of the few records of an adult reflecting in depth on the experience of being in analysis as a child. Yet to date this work has received little attention in the psychoanalytic literature. In an attempt to redress this neglect, the Heller case study is placed in the context of Anna Freud's emerging ideas about child analysis. In particular, its significance in the development of her psychoanalytic thinking is investigated in the light of her 1927 book, The Technique of Child Analysis.

    Full Text Available Peter Greenaway, director and artist is rethinking the notion of cinema in relation to other media and technologies, such as TV, painting, theater. “The Cinema is Dead! Long Live the Cinema!” is an interpretation of the known phrase that implies the continuation of the institution in spite of changes in personell. During the short history of cinema as an “aesthetic technology”, or “technological aesthetics”, Greenaway recognizes three periods of style which correspond to Winckelmann’s periodization of art: birth, maturity and decline. The director builds his thesis on the maturity of cinema of today in this premise, claiming that the cinema not annihilated, but invogorated by new technologies, which enrich both the cinema and our aesthetic experience. According to Greenaway, cinema has a glorious future.

    2013-08-01

    Full Text Available This Article discusses the question pertaining to the primacy of the Pope of Rome from the fi rst to the eighth centuries. The author criticizes the Roman Catholic teaching of the primacy of the pope as well as papal infallibility both of which were promulgated at the First Vatican Council in 1870. The author’s sources include an analysis of the proof texts employed by the Council: texts from scripture, from the works of early Christian fathers (Saint Ireneus and Saint Ambrose, from the works of the roman Pontiff s (Leo the Great, Hormisdus, and Gregory the great, on which the Council based its assumptions regarding the primacy of Peter and of the roman pontiff s. A panoramic view and detailed study of these documents lead the author to conclude that the doctrine of primacy has no real foundation in fact. The scriptures underscore the significance but not the particular office of Peter whose importance is founded in the fact that the apostle was at the head of the Christian community in Jerusalem. The Council incorrectly understood the proof texts on which it based the primacy doctrine separating them from their historical and social Sitz im Leben. The author pays particular attention to the historical circumstances surrounding the particular position of Rome as the capital city, the unique, for the western half of the Empire, apostolic origin of the see, its distance from Constantinople, and the relative independence of the popes in the face of the Byzantine emperors, an understanding which was not at all shared by the Eastern Churches. The author concludes that the pretensions of the popes to primacy were never accepted by the whole of the Church.

    The Cambro-Ordovician strata of the Midwest of the United States is a primary target for potential geological storage of CO2 in deep saline formations. The objective of this project is to develop a comprehensive evaluation of the Cambro-Ordovician strata in the Illinois and Michigan Basins above the basal Mount Simon Sandstone since the Mount Simon is the subject of other investigations including a demonstration-scale injection at the Illinois Basin Decatur Project. The primary reservoir targets investigated in this study are the middle Ordovician St Peter Sandstone and the late Cambrian to early Ordovician Knox Group carbonates. The topic of this report is a regional-scale evaluation of the geologic storage resource potential of the St Peter Sandstone in both the Illinois and Michigan Basins. Multiple deterministic-based approaches were used in conjunction with the probabilistic-based storage efficiency factors published in the DOE methodology to estimate the carbon storage resource of the formation. Extensive data sets of core analyses and wireline logs were compiled to develop the necessary inputs for volumetric calculations. Results demonstrate how the range in uncertainty of storage resource estimates varies as a function of data availability and quality, and the underlying assumptions used in the different approaches. In the simplest approach, storage resource estimates were calculated from mapping the gross thickness of the formation and applying a single estimate of the effective mean porosity of the formation. Results from this approach led to storage resource estimates ranging from 3.3 to 35.1 Gt in the Michigan Basin, and 1.0 to 11.0 Gt in the Illinois Basin at the P10 and P90 probability level, respectively. The second approach involved consideration of the diagenetic history of the formation throughout the two basins and used depth-dependent functions of porosity to derive a more realistic spatially variable model of porosity rather than applying a

    It is a mistake to think that all personal experiences with cancer are the same. For certain, all cancer patients do confront the possibility of an early death and the prospect of pain and suffering due to the tumor and its treatment. But the specific emotional issues differ with each patient and each family, and the responses to these issues take many forms. In an eloquent and moving film, "Cancer: A Personal Journey. Notes from the Edge.," we are given the privilege of accompanying a remarkable young physician, Peter J. Morgan, on his journey with cancer, a two and one-half year journey that ended with his death at age 31. At age 29, Dr. Morgan, an internist-in-training who intended to pursue a career in hematology and oncology, noted a mass on his leg. Tragically, metastasis to the lungs had already taken place at the time of diagnosis of a synovial sarcoma. There followed the all-too-familiar story of chemotherapy and experimental treatments, pain, debilitation, and ultimately demise, and in itself this experience would move us with the sorrow of a precious life lost. What makes this particular story so remarkable are the insights of this young physician and the struggle for survival of a spirit that would not succumb to the "chaos" of cancer. In the two-year period of his life as a cancer patient, Peter Morgan kept a diary that records his thoughts, his emotional turmoil, and his reflections on life and an untimely death. In particular, we are able to understand the need for his spiritual self to remain alive and to grow despite the deterioration of his physical being. And we see that spiritual triumph in his compelling relationships with his family and his colleagues, in his reflections on art and music and nature, and most of all in his writings and his appreciation of the immense possibilities for joy in life. This is not an easy journey to watch, but the intense sadness of his experience is balanced by his friendships and the great satisfaction he derived

    The area of the Gulf of Peter the Great is socially, economically and culturally one of the most important regions for the Russian Far East. At the same time, there have been reported palpable natural hazards, which pose a real threat to local infrastructure. Complex field team of the Gramaberg VNIIOkeangeologia institute carried out geological and geophysical studies of natural hazards in the water area and coastal zone of the gulf in the summer and autumn of 2012. The research program included - geodetic deformation monitoring of the coastal zone by the HDS 3000 Leica tachometer; - echo sounding of the underwater part of the coastal slope by the LCX-37C depth sounder equipped with active external 12-channel GPS Lowrance antenna LGC-3000; - high-frequency acoustic profiling by GeoPulse Subbotom Profilier with oscillator frequency of 12.2 kHz for the study of bottom sediments to a depth of 40 m; - hydromagnetic measurements by SeaSPY Marine Magnetics magnetometer for investigation of deep geological structure; - sonar measurements by GEO SM C-MAX, 325 kHz frequency emitters for studying seafloor features; - studies of the water column (sensing and sampling); - bottom sediment sampling. Analytic work was performed by mass spectrometry, atomic absorption spectrophotometry, chromatography, gas chromatography-mass spectrometry, gamma spectrometry and included the following. For water - the content of Fe, Mn, Cd, As, Pb, Cu, Co, Ni, Cr, Zn, Hg in solution and in suspension, polycyclic aromatic compounds, organochlorine pesticides, oil, methane. For sediments - grade analysis, mineralogical analysis of sand, determination of Fe, Mn, Cd, As, Pb, Cu, Co, Ni, Cr, Zn, Hg content; identification of petroleum products, polychlorinated biphenyls, organochlorine pesticides, the specific activity of Cs-137. As a result, a set of geological maps was composed: maps of pre-Quaternary and Quaternary rocks and deposits, lithological map, geomorphological map, map of engineering

    Leptin is an important cytokine for regulating energy homeostasis, however, relatively little is known about its function and control in teleost fishes or other ectotherms, particularly with regard to interactions with the growth hormone (GH)/insulin-like growth factors (IGFs) growth regulatory axis. Here we assessed the regulation of LepA, the dominant paralog in tilapia (Oreochromis mossambicus) and other teleosts under altered nutritional state, and evaluated how LepA might alter pituitary growth hormone (GH) and hepatic insulin-like growth factors (IGFs) that are known to be disparately regulated by metabolic state. Circulating LepA, and lepa and lepr gene expression increased after 3-weeks fasting and declined to control levels 10days following refeeding. This pattern of leptin regulation by metabolic state is similar to that previously observed for pituitary GH and opposite that of hepatic GHR and/or IGF dynamics in tilapia and other fishes. We therefore evaluated if LepA might differentially regulate pituitary GH, and hepatic GH receptors (GHRs) and IGFs. Recombinant tilapia LepA (rtLepA) increased hepatic gene expression of igf-1, igf-2, ghr-1, and ghr-2 from isolated hepatocytes following 24h incubation. Intraperitoneal rtLepA injection, on the other hand, stimulated hepatic igf-1, but had little effect on hepatic igf-2, ghr1, or ghr2 mRNA abundance. LepA suppressed GH accumulation and gh mRNA in pituitaries in vitro, but had no effect on GH release. We next sought to test if abolition of pituitary GH via hypophysectomy (Hx) affects the expression of hepatic lepa and lepr. Hypophysectomy significantly increases hepatic lepa mRNA abundance, while GH replacement in Hx fish restores lepa mRNA levels to that of sham controls. Leptin receptor (lepr) mRNA was unchanged by Hx. In in vitro hepatocyte incubations, GH inhibits lepa and lepr mRNA expression at low concentrations, while higher concentration stimulates lepa expression. Taken together, these findings

    In 1933 the Turkish Republic formally offered university positions to 30 German-speaking academics who were dismissed with the coming to power of the National Socialist Government. That initial number went up to 56 with the inclusion of the technical assistants. By 1948 the estimated total had increased to 199. Given renewable five-year contracts with salaries substantially higher than their Turkish counterparts, the foreign émigrés were to implement the westernization program of higher education. The ten year-old secular Turkish Republic's extensive social reforms had encompassed the adoption of the Latin alphabet, and equal rights for women, removing gender bias in hiring. Such a high concentration of émigré academics in one institution, "the highest anywhere in the world," provides a unique opportunity to study a subject which has been neglected. In this article two cases in psychology will be examined: Wilhelm Peters (1880-1963), who came, via Britain, to Istanbul in 1936 from the University of Jena in Germany, and Muzafer Sherif (1906-1988) who went to the United States from Ankara University in 1945. The purpose of the comparative analysis is to identify the features that are specific to the German experience, and those that are shared and underlie translocation in science within the multifaceted complexity of the process of forced migration.

  18. Cato Guldberg and Peter Waage, the history of the Law of Mass Action, and its relevance to clinical pharmacology.

    Ferner, Robin E; Aronson, Jeffrey K

    2016-01-01

    We have traced the historical link between the Law of Mass Action and clinical pharmacology. The Law evolved from the work of the French chemist Claude Louis Berthollet, was first formulated by Cato Guldberg and Peter Waage in 1864 and later clarified by the Dutch chemist Jacobus van 't Hoff in 1877. It has profoundly influenced our qualitative and quantitative understanding of a number of physiological and pharmacological phenomena. According to the Law of Mass Action, the velocity of a chemical reaction depends on the concentrations of the reactants. At equilibrium the concentrations of the chemicals involved bear a constant relation to each other, described by the equilibrium constant, K. The Law of Mass Action is relevant to various physiological and pharmacological concepts, including concentration-effect curves, dose-response curves, and ligand-receptor binding curves, all of which are important in describing the pharmacological actions of medications, the Langmuir adsorption isotherm, which describes the binding of medications to proteins, activation curves for transmembrane ion transport, enzyme inhibition and the Henderson-Hasselbalch equation, which describes the relation between pH, as a measure of acidity and the concentrations of the contributory acids and bases. Guldberg and Waage recognized the importance of dynamic equilibrium, while others failed to do so. Their ideas, over 150 years old, are embedded in and still relevant to clinical pharmacology. Here we explain the ideas and in a subsequent paper show how they are relevant to understanding adverse drug reactions. © 2015 The British Pharmacological Society.

  19. Technical note: Fu-Liou-Gu and Corti-Peter model performance evaluation for radiative retrievals from cirrus clouds

    We compare, for the first time, the performance of a simplified atmospheric radiative transfer algorithm package, the Corti-Peter (CP) model, versus the more complex Fu-Liou-Gu (FLG) model, for resolving top-of-the-atmosphere radiative forcing characteristics from single-layer cirrus clouds obtained from the NASA Micro-Pulse Lidar Network database in 2010 and 2011 at Singapore and in Greenbelt, Maryland, USA, in 2012. Specifically, CP simplifies calculation of both clear-sky longwave and shortwave radiation through regression analysis applied to radiative calculations, which contributes significantly to differences between the two. The results of the intercomparison show that differences in annual net top-of-the-atmosphere (TOA) cloud radiative forcing can reach 65 %. This is particularly true when land surface temperatures are warmer than 288 K, where the CP regression analysis becomes less accurate. CP proves useful for first-order estimates of TOA cirrus cloud forcing, but may not be suitable for quantitative accuracy, including the absolute sign of cirrus cloud daytime TOA forcing that can readily oscillate around zero globally.

    2001-02-01

    One of the world's most enduring companies, Nestle epitomizes everything that today's high-flying, headline-grabbing companies are not. It respects technology but doesn't consider it central to strategy. It values growth but prefers it controlled. It seeks talented professionals but wants only those who are modest in word and deed. Nestle CEO Peter Brabeck is skeptical of the relentless push for radical transformation heard from every quarter. He believes, instead, in continuous improvement through slow and steady change. Big, dramatic change is fine for a crisis, Brabeck says, but not every company is in crisis all the time. Many companies are like Nestle--performing well, growing and innovating, without frenzy, without bloodshed. While he acknowledges that every company must change in order to compete in today's turbulent marketplace, Brabeck makes the focus of his work identifying and strengthening those aspects of Nestle that should stay the same. For example, Nestle eschews the noise and energy swirling around technology. Many companies make technology the focal point of strategy, Brabeck says, but Nestle is about people, products, and brands. The company uses technology to create better products but keeps it in its right place--the background. Brabeck also talks candidly about how to fight complacency in a successful company, how to institutionalize collaboration in a decentralized organization, and how to resist pressure from analysts and money managers and focus on long-term, sustainable and profitable growth--in short, how to win the war without the revolution.

    2012-12-01

    Full Text Available In his latest novel Parrot and Olivier in America (2009 the Australian-born novelist Peter Carey explores the way three seemingly incompatible civilisations translate the New World. On the one hand Olivier, the snobbish French aristocrat, struggles to understand the concept of democracy in America because he wants to translate it ‘literally’ into his own system (of behaviour, social convenience, pragmatics, etc.. On the other hand, Parrot, the British-Australian pícaro and Olivier’s “clown and secretaire”, enjoys rewriting his master’s awful calligraphy, changing some of the Frenchman’s views on America according to his whim, and deliberately acting as a bad translator. Thirdly, the American free citizen, the “Man of the Future” (p. 187: s/he uses language creatively, coining a personal idiolect as evidence of belonging to a nation at its début, where “greed might tear the land apart but still the low could climb so high” (p. 251. This paper aims at illustrating how these three entities translate other systems of values, or their loss of values, into systems with which they can identify. The theoretical framework of my study proceeds from the contributions of Yuri Lotman, the main representative of the Tartu-Moscow school of semiotics.

    The Saint Peter and Saint Paul Islands are located at 0 degree 55.00' N and 29 degree 20.76'' W, at a distance of circa 550 M (nautical miles) NE from the City of Natal, RN (Northeast Region of Brazil), and comprises of many small islands and rocks of igneous plutonic origin. In 1998, a first Scientific Station was built in order to receive researchers involved in several projects. The CEPEL, as responsible by the electrical energy supply to the Scientific Station; designed and installed a PV electric energy generation system which had a power of 3.6 kWp. This system operated successfully for the last 10 years, suffering frequent maintenance. In 2006, a new design for the Scientific Station has been started aiming to improve its resources and safety. The new PV system has a maximum power of 7.8 kWp, and employs an updated technology (SMA, Germany). The equipment was integrated and submitted to intensive testing at facilities of CEPEL, and was installed and commissioned at the Islands in June 2008. Since the installation, the equipment has been operating as required, meeting the energy and water demand of the Station. The present paper describes the many steps involved in the implantation of the PV system at the Scientific Station. (author)

    Full Text Available Taking (inauthenticity as his subject and intertextuality as the structuring principle, Peter Carey brings together Australian literary and social history, literary theory and a self-reflexive probe into the issues of identity, authenticity and cultural insecurity of a postcolonial society. The novel is interpreted as an allegorical account of national history and an allegorical narrative on the theoretical matters of originality and authorship.Keywords: Carey, identity, (inauthenticity, intertextuality, text, postcolonialism. The most well-known Australian author today, Peter Carey, has more than once found inspiration for his novels in already existing texts of British and Australian cultures. The most notable examples are his sixth novel titled Jack Maggs, his seventh novel titled True History of the Kelly Gang and the one explored in this paper, his eighth novel titled My Life as a Fake. Carey’s Jack Maggs (1997 retells the story of Dickens’ Great Expectations and in a postcolonial fashion of re-writing imperial texts gives voice to the previously marginalised point of view so that the story is told from the perspective of the runaway convict, Magwitch. The Booker Prize winning True History of the Kelly Gang (2001 is inspired by the so-called “Jerilderie letter,” which was written by Australia’s most famous outlaw, Ned Kelly, after a bank robbery in 1879. The fifty-six page long original letter is expanded in Carey’s version into thirteen parcels which actually make up this epistolary novel. My Life as a Fake (2003 is a roman a clef based on the literary hoax which took place in Melbourne in 1944 and assumed an Ossianic significance in the Australian literary establishment. Wishing to explore the depths of degradation which, in their opinion, Australian modernist poetry had reached, two young disgruntled poets, Harold Stewart and James McAuley, conjured up a fictitious poet, Ern Malley, a mechanic and the author of The Darkening

    High-dose therapy (HDT) with autologous bone marrow or blood cell transplantation for the treatment of lymphoma commenced at Peter MacCallum Cancer Institute in 1986. To examine the patient characteristics and outcomes of patients with non-Hodgkin's lymphoma (NHL) and Hodgkin's disease (HD) treated with HDT and autologous transplantation at our Institute in the first 10 years of the service (1986-95). A retrospective analysis was performed examining patient characteristics, prior chemotherapy regimens, pretransplant disease status, HDT regimen, source of stem cells, time for haematopoietic recovery, complications of transplantation, response rates, overall survival (OS) and progression-free survival (PFS). Sixty-seven patients with NHL were treated with an estimated 5-year OS rate of 44% (95% confidence interval (CI) 32-56%) and PFS rate of 34% (95% CI 21-44%). Factors independently predictive of an unfavourable PFS on multivariate analyses were presence of constitutional symptoms at transplant (P < 0.002) and chemotherapy-resistant disease at transplant (P= 0.02). Twenty-three patients with HD were treated with a 5-year predicted OS rate of 74% (95% CI 56-92%) and PFS rate of 57% (95% CI 36-77%).There was no difference in PFS for HD patients who relapsed either within 12 months of completion of front-line therapy or after this time (P =0.5). The transplant-related mortality for the entire cohort was 17%, with a progressive decrease over time. HDT with autologous transplantation achieves durable PFS and OS in patients with lymphoma. Improved patient selection, therapy modifications according to prognostic factors and ongoing improvements in supportive care should improve outcomes further

    2011-06-01

    Full Text Available Este trabajo indaga la obra del artista Peter Rostovsky, el uso de la transposición  como recurso estético. El caso ofrece un ejemplo de cómo la transposición, en el marco de una tendencia artística que trabaja desde la deconstrucción de diferentes códigos o representaciones culturales, puede devenir un recurso que apela a una referencia compartida con un eventual espectador a fin de componer un discurso poético. Como hipótesis se considera que a través de este procedimiento el artista  reflexiona sobre el desplazamiento de hábitos de visibilidad y percepción en la cultura contemporánea. Este dispositivo, que revisita diferentes obras modernas, formula un enunciado que reflexiona sobre el estatuto de la experiencia en la actualidad. Para desarrollar el problema que el caso plantea se indagará específicamente sobre la serie Ephifany Models en la que el artista reelabora la obra del pintor Caspar Friedrich y, a través de él, los recursos pictóricos del romanticismo alemán. En esa reelaboración Rostovsky traslada el texto decimonónico a una nueva materia significante, este desplazamiento que el artista establece entre el discurso romántico y los recursos del arte contemporáneo comprometen valoraciones sociales y culturales que producen un cambio de sentido del texto fuente constituyendo una transposición.

    Full Text Available Contrary to the idea of following a precise conceptual plan in what concerns translation choices and beliefs, and to the detriment of traditional more prescriptive views on translation techniques, the possibility of intuition and creativity surface from contemporary critiques upon the matter. Such shift has not only bestowed translations with a deserved arena for them to perform their task, but has actually provided them with important tools for one to position him/herself socially and politically in what regards an issue that have always been social and political: the text. When I kidnap meaning from the original and suggest it actually belongs to every instance that happens to touch it, the autonomy inevitably directed by this process towards translator and reader ultimately grants both an opportunity to inflict a material and consistent influence on such meaning. That  is, when I pose that meanings do not belong to the original, such meanings end up losing their status of “possessions” – and eventually one learns they do not belong to anyone at all. The question one might be asking is: why would this autonomy to transform necessarily change anything for those involved in the enterprise of translation? Well, it does change many things; not to say everything. As translators acknowledge the active role they play for the maintenance or alteration of certain narratives, their task is no longer taken as a simple – uncontrollable – code transferring; i.e., translators are turned from rewriters into writers, from carriers  of old meanings into inventers of new ones. In the book Interconnecting Translation Studies and Imagology (2015 – edited by Peter Flynn, Luc van Doorslaer, and Joep Leerssen – the authors and compiled articles address the fact that it is only through a more autonomous notion of translation that questionable cultural aspects, as well as prejudiced images of this or that tradition, might be finally overcome.

    This article begins with the writings of the efforts of certain groups who try to incorporate the information that is misunderstanding and conflict with modern scientific facts relating to the dangers of nuclear power plants and radioactive waste. At the same time these people try analyzes the idea that the solar panels and windmills can produce enough electricity to replace fossil fuels and nuclear power is not required to make. During the period of human life, the various forms of energy have been applied. In life and art that developed at this time, more energy is needed. Accordingly, the fourth-generation nuclear reactor with a production capacity of high temperature operation and is said to have special advantages for the supply of cheap energy and no pollution, is needed in developing countries.

    The nature and distribution of organic carbon in marine waters depends on: 1) biological productivity and revenue of the autochthonous organic matter to the bottom; 2) sediment grain-size composition and conditions of dumping, which in turn depends of hydrothermic regime, topography, speed River mist and received major erosion products; 3) living conditions of the benthos (the quantity consumed of OM, gas regime of habitats, physiological capacity of heterotrophs). Autochthonous OM of phytoplankton plays a dominant role in the processes of formation of humus in aquatic conditions. Bottom sediments at different distance from the shoreline to depths from 0.5 up to 480 m of the Sea of Japan, which are formed in various conditions of facies, were selected as the objects of study. There is no clear relationships to the amount of organic matter in bottom sediments on the characteristics of the distribution and nature of living matter in the oceans and seas. This is because the process of sedimentation and fossilization of organic matter on the seabed and the ocean floor depends on many factors (currents, depth). Humus of studied bottom sediments in composition can be attributed mainly to the humic type. Nonhydrolyzing rest is 70-90%. This is characteristic of bottom sediments formed in facial types of small bays, internal coastal shelf bights and the underwater slope. At a fraction of the carbon of humic acids in organic matter, ranging from 4 to 80% of the amount of humic and fulvic acids. Fulvic acids content is much less. This is due to more favourable conservation situation of humic acids in precipitation with high content of organic matter, whereas fulvic acids in aquatic environments are more labile and almost not dumped. Despite the fact humic acids are not the most stable component (s), however, with increased content of humic acids, the mobility of organic matter and removing it from the bottom sediments are reduced.

    Full Text Available The family Phyllostomidae belongs to the most abundant and diverse group of bats in the Neotropics with more morphological traits variation at the family level than any other group within mammals. In this work, we present data of chromosome banding (G, C and Ag-NOR and Fluorescence In Situ Hybridization (FISH for representatives of Rhinophylla pumilio Peters, 1865 collected in four states of Brazil (Amazonas, Bahia, Mato Grosso and Pará. Two karyomorphs were found in this species: 2n=34, FN=64 in populations from western Pará and Mato Grosso states and 2n=34, FN=62 from Amazonas, Bahia, and northeastern Pará and Marajó Island (northern. Difference in the Fundamental Number is determined by variation in the size of the Nucleolar Organizer Region (NOR accompanied with heterochromatin on chromosomes of pair 16 or, alternatively, a pericentric inversion. The C-banding technique detected constitutive heterochromatin in the centromeric regions of all chromosomes and on the distal part of the long arm of pair 15 of specimens from all localities. FISH with a DNA telomeric probe did not show any interstitial sequence, and an 18S rDNA probe and silver staining revealed the presence of NOR in the long arm of the pair 15, associated with heterochromatin, and in the short arm of the pair 16 for all specimens. The intra-specific analysis using chromosome banding did not show any significant difference between the samples. The comparative analyses using G-banding have shown that nearly all chromosomes of R. pumilio were conserved in the chromosome complements of Glossophaga soricina Pallas, 1766, Phyllostomus hastatus Pallas, 1767, Phyllostomus discolor Wagner, 1843 and Mimon crenulatum Geoffroy, 1801, with a single chromosomal pair unique to R. pumilio (pair 15. However, two chromosomes of M. crenulatum are polymorphic for two independent pericentric inversions. The karyotype with 2n=34, NF=62 is probably the ancestral one for the other karyotypes

    Full Text Available Feeding aspects of the oilfish, Ruvettus pretiosus, were studied based on 360 stomachs of both male and female specimens caught off the Saint Peter and Saint Paul Archipelago. The total length of the specimens ranged from 52.4 cm to 189.0 cm. Of the 360 stomachs examined, 135 presented some food and 225 were empty. Thirty-four taxa were identified, represented by 16 fish, 17 cephalopods and 1 crustacean. The stabilization of the food items richness was attained at 35 food items and 104 stomachs, approximately. A remarkable predation upon the flying fish Cheilopogon cyanopterus was observed around SPSPA, directly related to the main reproductive period of this species in the area. The oilfish's food spectrum shows that the species feeds on a wide vertical range in the water column, catching prey items at the surface or in shallow waters, as well as epi-mesopelagic fish, in addition to mesopelagic cephalopods.Aspectos alimentares do peixe-prego, Ruvettus pretiosus, foram estudados com base nos estômagos de 360 espécimes, de ambos os sexos, capturados nos arredores do Arquipélago de São Pedro e São Paulo. Todos os exemplares foram capturados com linha de mão. O comprimento total dos exemplares variou de 52,4 cm a 189,0 cm. Dos 360 estômagos examinados, 135 apresentaram algum alimento e 225 estavam vazios. Trinta e quatro táxons foram identificados, representados por 16 peixes, 17 cefalópodes e um crustáceo. A estabilização da riqueza dos itens alimentares foi obtida com 35 itens e 104 estômagos. Uma predação notável sobre o peixe-voador Cheilopogon cyanopterus foi observada nas adjacências do ASPSP, diretamente relacionada com o principal período reprodutivo dessa espécie na área. O espectro alimentar do peixe-prego mostra que a espécie se alimenta em uma ampla faixa vertical na coluna d'agua, capturando desde presas de superfície ou águas rasas, a peixes epi-mesopelágicos, além de cefalópodes mesopelágicos.

  3. «I’ll kill him and I’ll eat him!»: Peter Greenaway and the cinematic Trauerspiel

    2017-11-01

    Full Text Available The career of British director Peter Greenaway, now more than four decades long, has often been animated by a profound interest in what one may call the aesthetics of death. This is particularly true for his 80s and 90s films, which explore a wide array of strategies for the staging and ritualization of death. In The Cook, the Thief, his Wife & Her Lover (1989, for the first time, this interest takes Greenaway into the territories of the tragic.I propose to rethink the fundamental relationship that Greenaway’s film entertains with the narrative and aesthetic forms of the tragic. More precisely, I suggest to interpret The Cook in the light of the reflections on the Trauerspiel (mourning-play that Walter Benjamin elaborates in The Origin of German Tragic Drama [Ursprung des deutschen Trauerspiels]. After giving a short account of the first macro-section of Benjamin’s essay, I will argue that the opposition between the Thief and the Lover mirrors the Trauerspiel’s opposition between Tyrant and Martyr, that Benjamin regards as one of the conceptual cores of this theatrical form. This, in turn, reflects the presence in the film of a more abstract conflict between two systems for the construction of knowledge and experience. By drawing on Benjamin’s study, I will trace this conflict back to the opposition between nature and books in baroque culture.The battle between the Thief/Tyrant and the Lover/Martyr takes the form of a succession of rites and counter-rites for the (unmaking of social bonds, and the film constructs these rites by clearly referring to the Christian imagination and its subversion. I will contend that the motif of the subversion of the Holy Communion can provide us with a unifying key for the interpretation of the film. From a semiotic perspective, this manipulation consists in the substitution of what our culture constructs as food with its dysphoric counterparts: decay, excrement, and human flesh.

    Analysis of the effectiveness of guppy (Poecilia reticulata Peters) immunization based on measurements of antibody (Ab) titers suffers from a shortage of reagents that can detect guppy antibodies (Abs). To overcome this problem, we immunized mice with different preparations of guppy immunoglobulins (Igs) and used the mouse antisera to develop a quantitative enzyme-linked immunosorbent assay (ELISA). The most efficient immunogen for mouse immunization was guppy Igs adsorbed on protein A/G beads. Antisera from mice boosted with this immunoglobulin (Ig) preparation were highly specific and contained high Ab titers. They immunoreacted in a Western blot with Ig heavy and light chains from guppy serum, and Ig heavy chain from guppy whole-body homogenate. The mouse anti-guppy Ig was applied in an ELISA aimed at comparing the efficiency of different routes of guppy immunization against Tetrahymena: (i) anal intubation with sonicated Tetrahymena (40,000 Tetrahymena/fish in a total volume of 10 μL) mixed with domperidon, deoxycholic acid and free amino acids (valine, leucine, isoleucine, phenylalanine and tryptophan), or (ii) intraperitoneal (i.p.) injection of sonicated Tetrahymena in complete Freund's adjuvant (15,000 Tetrahymena/fish in total a volume of 20 μL). Negative control fish were anally intubated with the intubation mixture without Tetrahymena, or untreated. ELISA measurement of anti-Tetrahymena Ab titer revealed a significantly higher level of Abs in i.p.-immunized guppies, compared to the anally intubated and control fish. In addition, the efficiency of immunization was tested by monitoring guppy mortality following (i) i.p. challenge with Tetrahymena (900 Tetrahymena/fish) or (ii) cold stress followed by immersion in water containing 10,000 Tetrahymena/mL. Fish mortality on day 14 post-Tetrahymena infection by i.p. injection exceeded 50% in the control and anally intubated fish, compared to 31% in i.p.-immunized fish. Immunization did not protect from

    A detailed oxygen isotope study of detrital quartz and authigenic quartz overgrowths from shallowly buried (ratio by laser fluorination, resulting in an average δ 18O of 10.0 ± 0.2‰ (1SD, n = 109). Twelve thin sections were analyzed by CAMECA-1280 ion microprobe (6-10 μm spot size, analytical precision better than ±0.2‰, 1SD). Detrital quartz grains have an average δ 18O of 10.0 ± 1.4‰ (1SD, n = 91) identical to the data obtained by laser fluorination. The ion microprobe data reveal true variability that is otherwise lost by homogenization of powdered samples necessary for laser fluorination. Laser fluorination uses samples that are one million times larger than the ion microprobe. Whole rock (WR) samples from the 53 rocks were analyzed by laser fluorination, giving δ 18O between 9.8‰ and 16.7‰ ( n = 110). Quartz overgrowths in thin sections from 10 rocks were analyzed by ion microprobe and average δ 18O = 29.3 ± 1.0‰ (1SD, n = 161). Given the similarity, on average, of δ 18O for all detrital quartz grains and for all quartz overgrowths, samples with higher δ 18O(WR) values can be shown to have more cement. The quartz cement in the 53 rocks, calculated by mass balance, varies from outlier at 33 vol.% cement. Eolian samples have an average of 11% cement compared to marine samples, which average 4% cement. Two models for quartz cementation have been investigated: high temperature (50-110 °C) formation from ore-forming brines related to Mississippi Valley Type (MVT) mineralization and formation as silcretes at low temperature (10-30 °C). The homogeneity of δ 18O for quartz overgrowths determined by ion microprobe rules out a systematic regional variation of temperature as predicted for MVT brines and there are no other known heating events in these sediments that were never buried to depths >1 km. The data in this study suggest that quartz overgrowths formed as silcretes in the St. Peter Sandstone from meteoric water with δ 18O values of -10

    The quality of abstracts presented at a conference reflects the academic activity and research productivity of the surgical/scientific association concerned. The abstract to publication rate (44.5 % internationally), is an important indicator of the quality of presented research. To evaluate the publication rate and impact of abstracts presented at the plenary session of the Sir Peter Freyer Surgical Symposium over a 25-year period (1989-2014), and identify factors influencing publication. Plenary abstracts were identified from abstract books of the Symposium from 1989-2014. The authors, institution, subspecialty and research subject were recorded. A Medline search with name of the first and last author, key words and content of all abstracts was conducted to identify related publications. The impact factor (IF) of the journal and the time to publication was recorded. 298 presented abstracts resulted in 168 publications (publication rate: 56 %). Basic Science research accounted for 80 % (n = 237) of the total number of presentations with the remaining 20 % (n = 61) being categorised as clinical research. Overall, cancer research accounted for 48 % of presented work. The average time to publication was 2 ± 7 years, while 11 % of all published studies achieved publication in the year of the symposium. The median impact factor for published research was 3.558 (IF range 0-39). These results indicate that the quality of papers presented at the Sir Peter Freyer Surgical Symposium compares favourably with international equivalents, making this meeting an important forum for Irish Academic Surgery.

  18. Metaphors of Postmodernism in Neo-Victorian Fiction: “The Trial of Elizabeth Cree” by Peter Ackroyd and “The Decorator” by Boris Akunin

    Olga A. Baratova

    2017-11-01

    Full Text Available One of the features that characterizes postmodern fiction is an intense interest in the past, and especially so – in Victorian period, chiefly in its sensational aspects. Therefore we witness a revival of Victorian crime novel and this tendency can be traced not only in recent English literature, but in other literatures as well, Russian in particular. This gave birth to the term “neo-Victorian novel”, referring to the pieces, which recreate the atmosphere of the period, introduce a lot of intertextual allusions and references to the well-known Victorian novels and exploit most popular subjects of the 19th century literature. However as we will argue in this essay the authors often use these plots as implicit metaphors of postmodern art as such. It will be demonstrated on the example of two Neo-Victorian novels – “The Trial of Elizabeth Cree” by Peter Ackroyd (1995 and “The Decorator” by Boris Akunin; for the latter Ackroyd’s novel can be also regarded as one of the precedent texts. Both novels give their versions of the story of Jack the Ripper but what is more important in our case – employ akin plot structures, images and artistic devices, which in fact become metaphoric actualization of postmodern techniques.

    Full Text Available This paper presents gravimetric and morphologic analyses based on the satellite-derived data set of EGM2008 and TOPEX for the area of the oceanic mantle massif of the Saint Peter and Saint Paul peridotite ridge, Equatorial Atlantic Ocean. The free-air anomaly indicates that the present plate boundary is not situated along the longitudinal graben which cuts peridotite ridge, but about 20 km to the north of it. The high Bouguer anomaly of the peridotite ridge suggests that it is constituted mainly by unserpentinised ultramafic rocks. The absence of isostatic compensation and low-degree serpentinisation of the ultramafic rocks indicate that the peridotite ridge is sustained mainly by active tectonic uplift. The unparallel relation between the transform fault and the relative plate motion generates near north-south compression and the consequent tectonic uplift. In this sense, the peridotite massif is a pressure ridge due to the strike-slip displacement of the Saint Paul Transform Fault.

However, one has to bare in mind the important fact that Richard Wagner founded his completely innovative festive institution mainly in order to carry out and to spread his regenerative Weltanschauung - already formulated in his numerous theoretical writings and incorporated into his musical dramas. The fact that Wagner’s Weltanschauung was based on the idea of changing the reality of everyday life by constructing the new reality, is of equal importance. Considering all this, it becomes appropriate to explain Wagner’s motivation for establishing the stage festival, as well as his idea of festival, from the standpoint of the theory of social construction of reality.

  1. Sea-level rise impacts on the temporal and spatial variability of extreme water levels: A case study for St. Peter-Ording, Germany

    Both the temporal and spatial variability of storm surge water level (WL) curves are usually not taken into account in flood risk assessments as observational data are often scarce. In addition, sea-level rise (SLR) can further affect the variability of WLs. We analyze the temporal and spatial variability of the WL curve of 75 historical storm surge events that have been numerically simulated for St. Peter-Ording at the German North Sea coast, considering the effects induced by three SLR scenarios (RCP 4.5, RCP 8.5, and a RCP 8.5 high end scenario). We assess potential impacts of these scenarios on two parameters related to flooding: overflow volumes and fullness. Our results indicate that due to both the temporal and spatial variability of those events the resulting overflow volume can be two or even three times greater. We observe a steepening of the WL curve with an increase of the tidal range under the three SLR scenarios, although SLR induced effects are relatively higher for the RCP 4.5. The steepening of the WL curve with SLR produces a reduction of the fullness, but the changes in overflow volumes also depend on the magnitude of the storm surge event.

  3. Arsenic release from chlorine-promoted alteration of a sulfide cement horizon: Evidence from batch studies on the St. Peter Sandstone, Wisconsin, USA

    Elevated As concentrations have been measured in wells in the St. Peter Sandstone aquifer of eastern Wisconsin, USA. The primary source is As-bearing sulfide minerals (pyrite and marcasite) within the aquifer. There is concern that well disinfection by chlorination may facilitate As release to groundwater by increasing the rate and extent of sulfide oxidation. The objective of this study was to examine the abiotic processes that mobilize As from the aquifer solids during controlled exposure to chlorinated solutions. Thin sections made from sulfidic aquifer material were characterized by quantitative electron probe micro-analysis before and after 24 h exposure to solutions of different Cl 2 concentrations. Batch experiments using crushed aquifer solids were also conducted to examine changes in solution chemistry over 24 h. Results of the combined experiments indicate that Cl 2 addition affects As release and uptake in two ways. First, Cl 2 increases oxidation of sulfide minerals, releasing more As from the mineral structure. Chlorine addition also increases the rate of Fe(II) oxidation and subsequent hydrous ferric oxide (HFO) precipitation, allowing for increased uptake of As onto the mineral surface. Although HFOs can act as sinks for As, they can release As if biogeochemical conditions (e.g. redox, pH) change. These results have implications not only for disinfection of drinking water wells in the study area, but also suggest that introduction of oxidants may adversely affect water quality during aquifer storage and recovery programs in aquifers containing As-bearing minerals.

    Full Text Available The aim of this study was to investigate the planktonic and the holobiont Madracis decactis (Scleractinia microbial diversity along a turbulence-driven upwelling event, in the world´s most isolated tropical island, St Peter and St Paul Archipelago (SPSPA, Brazil. Twenty one metagenomes were obtained for seawater (N=12, healthy and bleached holobionts (N=9 before, during and after the episode of high seawater turbulence and upwelling. Microbial assemblages differed between low turbulence-low nutrient (LLR and high-turbulence-high nutrient (HHR regimes in seawater. During LLR there was a balance between autotrophy and heterotrophy in the bacterioplankton and the ratio cyanobacteria:heterotrophs ~1 (C:H. Prochlorales, unclassified Alphaproteobacteria and Euryarchaeota were the dominant bacteria and archaea, respectively. Basic metabolisms and cyanobacterial phages characterized the LLR. During HHR C:H << 0.05 and Gammaproteobacteria approximated 50% of the most abundant organisms in seawater. Alteromonadales, Oceanospirillales and Thaumarchaeota were the dominant bacteria and archaea. Prevailing metabolisms were related to membrane transport, virulence, disease and defense. Phages targeting heterotrophs and virulence factor genes characterized HHR. Shifts were also observed in coral microbiomes, according to both annotation–indepent and -dependent methods. HHR bleached corals metagenomes were the most dissimilar and could be distinguished by their di- and tetranucleotides frequencies, Iron Acquision metabolism and virulence genes, such as V. cholerae-related virulence factors. The healthy coral holobiont was shown to be less sensitive to transient seawater-related perturbations than the diseased animals. A conceptual model for the turbulence-induced shifts is put forward.

    Full Text Available Botanical gardens' collections of living plants are valuable not only because of their exhibitions, but also because of the data accumulated during introductions of new plants. Inventory allows to collect valuable material about introduction of different types of plants (species and taxa. Analysis of the available information allows to select and recommend advanced species (genus complex for the needs of urbane floristics; the perennial herbaceous plants of mountain areas come in the first place. A new list of advanced ornamental and household plants is introduced in the article. The recommended plants can be used for urban gardening and various groundscape works, and for creation of seed orchards in the neighboring regions. The study of introduction results helps not only to determine the advanced species (and taxa, but to understand which spices will not be able to survive a long time in the new conditions (mainly because of the climate, for example in the North-West of Russia. Over the past 60 years, around 385 plants of 61 families has been introduced at the North American and Himalayan rock gardens of the Peter the Great Botanical Garden. In the 60s of the 20th century, the exposition of these rock gardens had nearly 130 species from 51 families, 20 years later – 254 plants of 55 families. In the beginning of the 21st century, there were 249 taxa of the 52 families. Since 2010, the Alpinarium had to undergo a major reconstruction following the restoration and addition of the collection. As of 2015, the exposition of the North American and Himalayan rock gardens has 200 species of 54 families.

    Norman McOmish Dott (1897-1973) developed surgical neurology in Edinburgh, Scotland, and was a scholar of worldwide renown. One of Dott's most notable contributions to neurosurgery was his understanding of hypothalamic physiology, mostly acquired through the comprehensive study of patients with lesions involving this region of the diencephalon, particularly craniopharyngiomas (CPs). Recognition of symptoms caused by hypothalamic disturbances allowed him to predict the accurate anatomical relationships between CPs and the hypothalamus, despite the rudimentary radiological methods available during the 1930s. His sophisticated knowledge permitted Dott to perform radical removals of CPs originating within the third ventricle floor with acceptable success. Between 1934 and 1937, he operated on 4 CP cases originating in the hypothalamus, achieving a satisfactory postoperative outcome in 3 of the 4 patients. Aware of the strong attachment of hypothalamic CPs to the infundibulo-tuberal area, Dott used a double transbasal and transventricular approach to these lesions, a strategy providing an optimal view and control of the tumor boundaries. The decisive mentorship of several legendary figures of physiology and neurosurgery greatly influenced Dott's surgical evolution. The experimental pituitary gland work he performed with Sir Edward Sharpey-Schäfer at the beginning of his career stirred Dott's curiosity about the issue of hypothalamus-pituitary relationships. As a result, he decided to move to Peter Bent Brigham Hospital (Boston, Massachusetts) in 1923, to train in neurosurgery and neuropathology under the guidance of the leaders in these fields, Harvey Williams Cushing (1869-1939) and Percival Sylvester Bailey (1892-1973). They inspired the young Dott and shared with him their clinical and pathological expertise, in addition to their surgical strategies for best approaching and removing these challenging tumors. In time, Dott would come to surpass his mentors. This

    As part of this twentieth anniversary special issue I was asked to write a few words about Richard Palmer, the one permanent fixture on the journal over its twenty year history. Richard and I go back a (very) long way! He began his career at IOP Publishing in Bristol in 1971 while my publishing career with the American Physical Society began a little earlier, located at Brookhaven National Laboratory on Long Island NY. Since then, and for nearly forty years we have met often, if irregularly, at many locations throughout the world. As members of two very strong physics organizations we were clearly in competition with each other to seek out and publish the best physics research. At the same time we frequently exchanged experiences and policy ideas for dealing with serious violations of scientific ethical standards and how academic society-run journals can best serve the general scientific community. Overall my relationship with Richard has been a most rewarding one and I shall miss his opinions and sage advice. Richard: Compatriot; competitor; collaborator; I salute you!

    Buckle, Stephen

    2005-01-01

    The paper begins by situating Singer within the British meta-ethical tradition. It sets out the main steps in his argument for utilitarianism as the 'default setting' of ethical thought. It argues that Singer's argument depends on a hierarchy of reasons, such that the ethical viewpoint is understood to be an adaptation--an extension--of a fundamental self-interest. It concludes that the argument fails because it is impossible to get from this starting-point in self-interest to his conception of the ethical point of view. The fundamental problem is its mixing the immiscible: the Humean subordination of reason to interest with the Kantian conception of reason as universal and authoritative.

    Full Text Available Analizamos el crecimiento corporal de una nueva especie de lagartija endémica del género Xenosaurus Peters, ubicada en la Reserva de la Biósfera, Sierra Gorda - Querétaro, México. Se estimaron las tasas de crecimiento corporal y se analizaron a partir de los modelos de crecimiento de Von Bertalanffy, logístico por longitud y logístico por peso. Para describir el patrón de crecimiento de estas lagartijas, utilizamos el modelo logístico por longitud debido a que fue el modelo que tuvo el mejor ajuste a las tasas observadas de crecimiento corporal. No encontramos diferencias significativas entre machos y hembras en el parámetro característico de crecimiento ni en la talla asintótica proyectada. Por lo tanto, se construyó una sola curva de crecimiento para ambos sexos. Los machos alcanzan la madurez sexual a los 24 meses, mientras que las hembras lo hacen hasta los 37 meses. Las tasas de crecimiento independientes de la talla no fueron estadísticamente diferentes entre años (2001, 2002 y 2003, ni entre estaciones (estación húmeda y seca. Nuestros resultados sugieren que la variación en el crecimiento corporal de esta especie, no es causada exclusivamente por las variaciones ambientales, sino más bien por una compleja combinación de factores ambientales y bases genéticas.We analyzed variation in body growth of a new lizard species of the genus Xenosaurus Peters that is endemic to the Biosphere Reserve, Sierra Gorda - Querétaro, México. We calculated body growth rates and analyzed them by means of the Von Bertalanffy, logistic-by-length, and logistic-by-weight growth models. We used the logistic-by-length model to describe the growth pattern of these lizards because this model provided the best fit to the observed body growth rates. No significant differences were found between males and females in the characteristic growth parameter or in the projected asymptotic size. Therefore, a single growth curve was constructed for both

    Full Text Available En este artículo se presenta una reflexión sobre la relación entre el crecimiento demográfico y la ética frente a la pobreza, a partir de una crítica a los argumentos presentados por Peter Singer en su libro "Ética Práctica". En primer lugar, se colocan en pocas palabras los propios argumentos del autor. A continuación, se analizan los "pilares" que sustentan su argumentación, intentando responder a las siguientes cuestiones: 1 ¿Es el "exceso de población" la principal causa de la pobreza? ¿podemos encontrar una relación entre pobreza y velocidad del crecimiento de la población? 2 ¿Está vigente la perspectiva demográfica que Singer asume? 3 ¿Se puede ignorar o restarle importancia al problema de la distribución de los recursos y los ingresos cuando estamos tratando el problema de la pobreza desde una perspectiva ética? 4 ¿Qué tan cierto es ese argumento del éxito en los casos de México, Colombia y Brasil en cuanto a la implantación de una política de control de la natalidad? 5 ¿Esa postura del autor sobre el crecimiento de la población tiene consecuencias negativas en el "imaginario colectivo"? Por último, a manera de conclusión, se presentan algunas cuestiones que deben ser consideradas en una ética frente a la pobreza.This article analyzes the relationship between population growth and ethical principles relating to poverty. The paper is a critical approach to the thesis presented by Peter Singer in his book "Practical Ethics". The first part briefly examines the principal topics of his thesis. The author then analyzes the basis of Singer's theory with respect to the following questions: 1 Is overpopulation the main reason for poverty? Is it possible to establish an association between the poverty phenomenon and population growth? 2 Is Singer´s demographic perspective valid? 3 Can problems of resource distribution be ignored when talking about poverty from an ethical perspective? 4 Is it true that birth control

    In the framework of the National School "Science and Cultural Heritage: from Non-Invasive Analysis to 3D Recostruction" (19-23 September 2016, Messina-Valle d'Agrò, Italy), organized by the Department of Mathematical and Computer Sciences, Physical Sciences and Earth Sciences of the University of Messina, in co-opeartion with the Department of Geosciences of the University of Malta and in agreement with the Regional Order of Geologists of Sicily, non-invasive investigations have been performed aimed at the exploitation, fruition and safeguard of the archaeological site of Scifì and the St Peter and Paul Church in Agro Valley. Different georadar prospections [1-2] were carried out at both sites. Prospections have been performed by using a Ris-Hi mode system equipped with a dual antenna at the central frequencies of 200 and 600 MHz [3], and made along an orthogonal grid with 40 cm spacing. Data processing involved a zero timing, background removal on all tracks, a gain in-depth, a one-dimensional Butterworth filtering and a Kirchoff migration. Measurements of ambient vibrations were also performed [4-5], that revealed the absence of remarkable side heterogeneities, or large impedance contrasts associated surface stratigraphy. Measurements were also taken to measure the natural frequency of the church. In the two investigated sites, we also conducted spectroscopic investigations. The analysis was mainly focused on the study of variations, in terms of elemental composition by means of X-ray fluorescence (XRF) measurements as well as Raman spectrospopy which allow to determine the elemental composition of the sample under investigation. In addition, several images (by means of drones) were also collected in order to create a detailed 3D model for each site the ultimate goal of creating a digital archive for the virtual use of sites of interest.

The texts of the four conversations were thoroughly examined by Eckhard Matthes (1987. The present paper explores how the illustrations to the 83rd–86th Entrevuë visualize the texts, which is significant as they were an important instrument for disseminating certain notions about Russia. While the illustration to the first dialogue of the suite juxtaposes Peter and Ivan, the illustration to the second one emphasizes the similarities between them. So the image of the “tyrant” and “barbarian” Ivan becomes a reference point with which a reader is urged to compare Peter’s deeds, seeing not only the differences but also the similarities. This greatly contributes to the creation of the multifaceted image of Russia of the early 18th century. The characters of the second illustration—a tiger and an executioner—can be identified as Ivan and Peter only if the reader takes into consideration an epigram to the illustration, the illustration to the previous dialogue, the text of the next Entrevuë, and facts about the execution of the strel’tsy known from other texts and images, about which Fassmann remains silent in the spirit of ars dissimulandi, which was typical for baroque culture. The paper offers an attempt to trace the iconography of the tyrant as a tiger. In the frontispiece to the 85th Entrevuë, a secretary bringing news from the world of the living and a portrait of Catherine I emphasize the connection of the past and the present, i.e., history and policy. Finally, the illustration to the last dialogue of the series returns to the glorification of Peter the Great declared in the first dialogue.

    2010-01-01

    An attempt has been made in the current paper to dispel two myths concerning Peter Simon Pallas, myths which have led historians of biology to distort the picture of some of the general biological ideas developed by that eminent naturalist of the Age of Enlightenment. The first point dealt with in the paper involves the myth that Pallas had allegedly drafted a 'tree of life' diagram, one of the many graphic representations of this kind to appear in later times, illustrating the structure of the organic world. The tree, of which Pallas merely left a short description (but not a depiction), took--in the articles of authors who wrote about it--a variety of graphic forms (largely dependent on the authors' pictorial inventiveness), with all the authors assuring the readers that they illustrated their reasoning with the help of Pallas's tree of life, but never mentioning that it was they themseIves who had drawn it. The current paper presents a juxtaposition of a number of such diagrams, drawn by different authors: the great diversity of the diagrams is sufficient proof that the existence of one, original 'Pallas tree' is just a myth. Another aspect of the myth has to do with the view that the tree supposedly illustrated phylogenetic dependencies - in fact, Pallas described affinity relationships between groups in the animal world. The present paper investigates how the 'tree of life' myth has developed, and reveals the mechanism that has most likely led to the myth being perpetuated in writings on the history of biology. The second issue discussed in the current paper relates to the myth of how Pallas's general views on biology allegedly evolved. The naturalist was supposed to have moved from transformism (characteristic of early stages of his work) to the idea of the immutability of species, formed in the period of his full scientific maturity. The current paper proves, inter alia on the basis of little known and not easily accessible writings by the scholar, that

    Sandra I Rodriguez Cruz

    Full Text Available Among the adaptations of aquatic species during evolution of terrestrial tetrapods was the development of an epidermis preventing desiccation. In present day mammals, keratinocytes of the epidermis, using a membrane-bound transglutaminase (Tgm1, accomplish this function by synthesizing a scaffold of cross-linked protein to which a lipid envelope is attached. This study characterizes the abilities of two homologous transglutaminase isozymes in the teleost fish tilapia to form cross-linked protein structures and their expression in certain tissues. Results indicate they are capable of membrane localization and of generating cellular structures resistant to detergent solubilization. They are both expressed in epithelial cells of the lip, buccal cavity and tips of gill filaments. Adaptation of transglutaminase use in evolution of terrestrial keratinocytes evidently involved refinements in tissue expression, access to suitable substrate proteins and activation of cross-linking during terminal differentiation.

  8. Intensive aquaculture of tilapia (Sarotherodon niloticus) in the thermal effluents of a nuclear power plant in Belgium

    International Nuclear Information System (INIS)

    Melard, Ch.; Philippart, J.C.

    1981-01-01

    This paper presents the results of three years of experiments in cultivating S. niloticus in the cooling waters of the nuclear power station at Tihange on the Meuse. The research station infrastructure consists of three earthen ponds measuring 150m 2 (volume: 200m 3 ) and 16 fibreglass tanks of 4m 2 (2m 3 ). These are fed by a pumping system (70m 3 /h) at the outlet point of the power station condenser. A regulation system ensures that the feed-water is kept at a safe thermal level (17-32 deg. C). The Meuse has a high biological productivity potential at Tihange; there is no chemical pollution of any significance, although moderate organic pollution exists. The thermal conditions in the river make it possible to count on nine months (March to December) during which the average utilizable water temperature for tilapia culture exceeds 20 deg. C. Under conditions of intensive-tank culture, it was possible to maintain a maximum biomass (with 150g fish) of 120kg/m 3 of tank with a water renewal rate of about 3.5 times per hour (loading: 2.1kg/liter per minute). A figure is provided showing the relation to weight of oxygen consumption and optimal loading at a temperature of 30-32 deg. C. The highest yields recorded are 21.1q/m 3 per hour and 25.7kg/m 3 of tank/month; with an average yield of 12g/m 3 per hour, a volume of 85m 3 of heated water is required to produce 1kg of S. niloticus from 20g of male fry. The fish are suitable for marketing (trial offer to restaurants) if they weigh 300-350g. Analysis shows that their heavy metals and radionuclide content is below the level permitted by law. (author)

  19. A Critical Appraisal of Peter Gowan’s “Contemporary Intra-Core Relations and World-Systems Theory”: A Capitalist World-Empire or U.S.-East Asian Geo-Economic Integration?

    Directory of Open Access Journals (Sweden)

    John Gulick

    2015-08-01

    Full Text Available This paper evaluates Peter Gowan’s musings on the topic of a U.S.-centered “capitalist world-empire.” Gowan’s heterodox concept of a “capitalist world-empire” is intellectually defensible. And his claim that U.S. hegemony is historically unique, because unlike previous dominant powers the U.S. has been able to distinctly mold the accumulation regimes and security environments of its would-be rivals in the core, is more than convincing. However, Gowan tends to overstate the degree to which the U.S. in the 1990’s enjoyed a productive sector revival, rather than a mere super-inflation of dollar-denominated assets. This tendency prevents him from anticipating just how summarily the U.S. would ditch consensual approaches to managing the capitalistworld-economy once the Wall Street bubble collapsed, and hence from appreciating just how fed up Western European and East Asian elites would become with the predatory character of U.S. hegemony in decay. In conclusion the paper argues that while the U.S. may have neither the resources nor the credibility to politically control the global division of labor, something akin to a U.S.-East Asian geo-economic bloc may be in the process of forming. This is so because the Chinese and Japanese economic growth models remain wedded to the underwriting of the U.S.’ seigniorage privileges', and because past and present frictions between China and Japan stand in the way of tighter Sino-Japanese political coordination.

    Full Text Available El fenómeno del cine virtual busca colmar una vieja aspiración por aprehender la condición esencial del teatro: la vivencia de un acontecimiento único e irrepetible por parte del espectador que contempla a unos actores enfrentados a situaciones en ese preciso instante. Ya en los años cincuenta se abordan experimentos con el cine en relieve(primer sistema 3D o, también, se emprenden búsquedas con el sentido del olfato(el smell-vision. La llegada de la revolución informática y su motion control system implica una nueva conquista en las sensaciones visuales del espectador y preludia la irrupción de un auténtico visionario en este sentido: Francis Ford Coppola. Su “cine electrónico” es un vehículo experimental para rodar con telecámaras y soporte magnético y, además, prepara el terreno para la aparición de los infogramas y la ruptura definitiva de la secuencia imagen-ojo-objeto, verdadero salto cualitativo hacia la pluridimensionalidad de la imagen. La creación con infogramas de realidades imaginarias y la revitalización del cine de género (Ciencia Ficción y Fantasy Films tiene un momento clave en el año 1999 con dos productos emblemáticos: Matrix y La amenaza fantasma.

    Full Text Available The present article seeks to show that, for the Dadaists, film was an unsatisfying medium because as a technically reproduced artifact it counteracted Dada’s sense of immediacy. The focus of my text revolves around the notion of “facticity” inspired by Wieland Herzfelde, for whom Dada represented a reaction to all attempts at disavowing the “factual.” Manifestations of Dada, such as the readymade, live performance, collage, photomontage and not least the photogram, attest to a radically new understanding of realism in art, adhering to an “anti-mimetic concept of realism” (Elsaesser. As I will argue, Dada did not capitulate to film, but made a ‘compromise,’ by exploring different strategies to reinsert the “factual“ into this medium of reproduction. This could be done by (1 turning a screening into a live performance, (2 eliciting a bodily reaction in the spectator, (3 experimenting with hand-made, camera-less devices of film making, and (4 calling to mind the material existence of the cinematic apparatus. What these strategies have in common is to minimalize (although not necessarily to abolish the distance between “reality” and its representation in order to maintain film’s initial tactility, as described by Walter Benjamin in “The Work of Art in the Age of Mechanical Reproduction.” Man Ray’s Le Retour à la raison (1923 and Marcel Duchamp’s Anémic cinéma (1924–26 are prototypes of the Dadaist ‘compromise.’ A similar impetus can be found in a more recent example, Dream Work (2001, the third part of Peter Tscherkassky’s CinemaScope-Trilogy, which explicitly refers to the early days of French experimental film. What these three films, despite their differences, have in common, is to privilege a certain immediacy (be it during the moment of production or during the moment of reception and to include an element of tactility, usually absent from cinematic works.

    1984-01-01

    The present experiment investigated the effects of adding pig manure and chicken manure as supplementary feeds for rearing Sarotherodon mossambicus (Tilapia mossambica) in the laboratory. The feeding test lasted for four weeks under stable aerated conditions. Various portions (10%, 40%, 60% w/w) of the two types of manure were mixed with dried tubifex worm pellets, whilst the control group consisted of tubifex worm alone. The metals studied were Mn, Fe, Cu and Pb. The diets supplemented with 40% and 60% manure contained significantly (p < 0.05) greater amounts of all the metals tested except iron. The concentration of metals in the fish tissues (gill, viscera, flesh) was related to the amount of manure supplement. Harmful effects were reflected by significantly lower (p < 0.05) protein content in fish fed on manure-supplement diets, with the sole exception of the 10% pig manure supplement. Histological damage was also observed in the gills and the hepatopancreas of fish fed on diets supplemented with 60% pig manure and with 40% or 60% chicken manure. Of the two kinds of animal manure investigated as potential supplementary feeds for rearing tilapia, the results indicate that pig manure is likely to be the better choice.

    In euryhaline teleosts, reorganization of gill tight junctions during salinity acclimation involves dynamic expression of specific claudin (Cldn) paralogs. We identified four transcripts encoding Cldn tight junction proteins in the tilapia gill transcriptome: cldn10c, cldn10e, cldn28a and cldn30. A tissue distribution experiment found cldn10c and cldn10e expression levels in the gill to be 100-fold higher than any other tissues examined. cldn28a and cldn30 levels in the gill were 10-fold greater than levels in other tissues. Expression of these genes in Mozambique tilapia was examined during acclimation to fresh water (FW), seawater (SW), and in response to hormone treatments. Transfer of tilapia from FW to SW elevated cldn10c and cldn10e, while cldn28a and cldn30 were stimulated following transfer from SW to FW. In hypophysectomized tilapia transferred to FW, pituitary extirpation induced reduced expression of cldn10c, cldn10e and cldn28a; these effects were mitigated equally by either prolactin or cortisol replacement. In vitro experiments with gill filaments showed that cortisol stimulated expression of all four cldns examined, suggesting a direct action of cortisol in situ. Our data indicate that elevated cldn10c and cldn10e expression is important during acclimation of tilapia to SW possibly by conferring ion specific paracellular permeability.

    Ca(2+) is a vital element for many physiological processes in vertebrates, including teleosts, which live in aquatic environments and acquire Ca(2+) from their surroundings. Ionocytes within the adult gills or larval skin are critical sites for transcellular Ca(2+) uptake in teleosts. The ionocytes of zebrafish were found to contain transcellular Ca(2+) transporters, epithelial Ca(2+) channel (ECaC), plasma membrane Ca(2+)-ATPase 2 (PMCA2), and Na(+)/Ca(2+) exchanger 1b (NCX1b), providing information about the molecular mechanism of transcellular Ca(2+) transports mediated by ionocytes in fish. However, more evidence is required to establish whether or not a similar mechanism of transcellular Ca(2+) transport also exists in others teleosts. In the present study, ecac, pmca2, and ncx1 were found to be expressed in the branchial ionocytes of tilapia, thereby providing further support for the mechanism of transcellular Ca(2+) transport through ionocytes previously proposed for zebrafish. In addition, we also reveal that low Ca(2+) water treatment of tilapia stimulates Ca(2+) uptake and expression of ecac and cyp11b (the latter encodes a cortisol-synthesis enzyme). Treatment of tilapia with exogenous cortisol (20 mg/l) enhanced both Ca(2+) influx and ecac expression. Therefore, increased cyp11b expression is suggested to enhance Ca(2+) uptake capacity in tilapia exposed to low Ca(2+) water. Furthermore, the application of cortisol receptor antagonists revealed that cortisol may regulate Ca(2+) uptake through glucocorticoid and/or mineralocorticoid receptor (GR and/or MR) in tilapia. Taken together, the data suggest that cortisol may activate GR and/or MR to execute its hypercalcemic action by stimulating ecac expression in tilapia.

  3. Sex-specific differences in the synaptonemal complex in the genus Oreochromis (Cichlidae).

    Campos-Ramos, Rafael; Harvey, Simon C; Penman, David J

    2009-04-01

    Total synaptonemal complex (SC) lengths were estimated from Oreochromis aureus Steindachner (which has a WZ/ZZ sex determination system), O. mossambicus Peters and O. niloticus L. (both of which have XX/XY sex determination systems). The total SC length in oocytes was greater than that in spermatocytes in all three species (194 +/- 30 microm and 134 +/- 13 microm, 187 +/- 22 microm and 127 +/- 17 microm, 193 +/- 37 microm and 144 +/- 19 microm, respectively). These sex-specific differences did not appear to be influenced by the type of sex determination system (the female/male total SC length ratio was 1.45 in O. aureus, 1.47 in O. mossambicus and 1.34 in O. niloticus) and do not correlate with the lack of any overall sex-specific length differences in the current Oreochromis linkage map. Although based on data from relatively few species, there appears to be no consistent relationship between sex-specific SC lengths and linkage map lengths in fish. Neomale (hormonally masculinized genetic female) O. aureus and O. mossambicus had total SC lengths of 138 +/- 13 microm and 146 +/- 13 microm respectively, more similar to normal males than to normal females. These findings agree with data from other vertebrate species that suggest that phenotypic sex, rather than genotype, determines traits such as total SC length, chiasmata position and recombination pattern, at least for the autosomes.

    2015-01-01

    Full Text Available Novel Sara of Petar Sarić consists of two parts; in it are processed or present two wars, two major wars in the region of Montenegro and Herzegovina, the First and Second World War. However, it is more novel about divisions within the family and the man himself, (and infamous assault of godfather Luka on Sarah also and his murder are in that function, in the first part; and on the divisions among the people, in general, in the second part of the novel. The second part is, in fact, the image layering of life, not a symbolic one, full of hope, faith, reliance, rather than a concrete, real life, that life which is transformed into a fear of life. Separate, poetical, part of the novel, is his main character, Sara. It is no coincidence that her name novel entitled. Because she is one of most beautiful characters in the newer Serbian prose. Speech about the Sara precedes speech about her book. The book is Sara, Sara's book! Possession of book is her main feature of the exterior. Sara comes out from the Book and disappears in the book. Self contained and independent, therefore doomed to conflict with the environment. Loyal to husband and family, loyal to the truth and for justice, she ,,not hurt anything and anyone, no one is standing in the way, to anyone not wroth, nor has anyone looked wrong.' At the same time, the strange beauty, beauty that could not fit into some sort of scheme, one particular image or idea of beauty that again and again renewed, changed, remaining distant, and unmet. Strange goodness, marvelous beauty, she suffered unusual way; her life was transformed into continuous abstinence, repression, in anxiety and fear. In a word: in martirizam! Finally, in order to safe­guard children, sacrificed herself. Novel is a strong critique of society which is not able to recognize the beauty / goodness!.

  11. Landscape by Moonlight: Peter Paul Rubens and Astronomy

    Science.gov (United States)

    Mendillo, M.

    2016-01-01

    In the last years of his life, Rubens (1577-1640) lived happily with his wife and children on his Het Steen estate. During this period he worked and reworked a painting that had special meaning to him—Landscape by Moonlight (1635-40), now at the Courtauld Gallery in London. After a highly successful career painting religious and secular portraits, allegories, and occasional landscapes, Rubens put an extraordinary amount of effort into this final landscape. He was well known as a person who would commit to memory ideas and themes that he would use in future works. This paper reviews Rubens' attention to the visualization of nature, his personal connections to Elsheimer, Galileo, and Peiresc, and explores his possible depiction of constellations recalled from memory and placed within the cloudy skies in his Landscape by Moonlight.

    In aquaculture, growth and sex are economically important traits. To accelerate genetic improvement in increasing growth in salt-tolerant tilapia, we conducted QTL mapping for growth traits and sex with an F2 family, including 522 offspring and two parents. We used 144 polymorphic microsatellites evenly covering the genome of tilapia to genotype the family. QTL analyses were carried out using interval mapping for all individuals, males and females in the family, respectively. Using all individuals, three suggestive QTL for body weight, body length and body thickness respectively were detected in LG20, LG22 and LG12 and explained 2.4% to 3.1% of phenotypic variance (PV). When considering only males, five QTL for body weight were detected on five LGs, and explained 4.1 to 6.3% of PV. Using only females from the F2 family, three QTL for body weight were detected on LG1, LG6 and LG8, and explained 7.9-14.3% of PV. The QTL for body weight in males and females were located in different LGs, suggesting that in salt-tolerant tilapia, different set of genes 'switches' control the growth in males and females. QTL for sex were mapped on LG1 and LG22, indicating multigene sex determination in the salt-tolerant tilapia. This study provides new insights on the locations and effects of QTL for growth traits and sex, and sets the foundation for fine mapping for future marker-assisted selection for growth and sex in salt-tolerant tilapia aquaculture.

    Full Text Available RESUMEN Eisenman superpone y entreteje tiempos distintos en sus ciudades de arqueología artificial donde a través de distintas estrategias de escalado y superposición (scaling y overlapping se rescatan momentos pasados que se yuxtaponen con instantes futuros. Ensamblaje, montaje, collage de distintas capas dan como resultado un trastrocamiento o una nueva re-significación. En algunas de estas ciudades las arqueologías eran ficticias, pero en otras eran reales, aunque superpuestas en un proceso de una absoluta artificialidad. Todas ellas son ejemplos donde la arquitectura revela su antigua condición de permanencia a la vez que asume la alteración como posibilidad de repensar lo existente. Eisenman es el ardid que lo hace posible, pasando del uso del signo al texto, de la sintaxis a la semántica y de la gramática a la memoria. En los proyectos que se estudian en este artículo se pasa de trabajar con objetos a trabajar con las huellas que los procesos dejan a modo de palimpsestos o mapas-operativos. SUMMARY Eisenman superimposes and interweaves different times in his cities of artificial archaeology where, through different strategies of scaling and superimposition, past times are rescued and juxtaposed with future moments. The assembly, montage, and collage of different layers result in a transformation or a re-signification. In some of these cities the archaeologies were fictitious, but in others they were real but superimposed in a process of absolute artificiality. These are all examples where architecture reveals its former condition of permanence while accepting change as a chance to rethink what exists. Eisenman is the clever device that makes it possible, passing from the use of the sign to the use of text, from syntax to semantics and from grammar to memory. The projects discussed in this article pass from working with objects to working with the traces that the processes leave, such as palimpsests or operational-maps.

  19. Prolactin receptors in liver, kidney, and gill of the tilapia (Oreochromis mossambicus): Characterization and effect of salinity on specific binding of iodinated ovine prolactin

    International Nuclear Information System (INIS)

    Dauder, S.; Young, G.; Hass, L.; Bern, H.A.

    1990-01-01

    Specific binding of 125 I-ovine prolactin (oPRL) to microsomal fractions from gill, kidney, and liver of adult tilapia was determined. Specific binding varied among tissues, the highest values being displayed by kidney membranes. In the liver, the binding of oPRL was not strongly displaced by tilapia prolactins (tPRL177 and tPRL188), although tPRL177 was six times more potent than tPRL188. On the other hand, in kidney and gill membranes, the two tPRLs were equipotent. Tilapia PRLs showed low potency in competing for oPRL-binding sites when pregnant rat liver membranes were utilized. Tilapia growth hormone (tGH) and human growth hormone (hGH) displaced 125 I-oPRL from liver as well as did tPRL177 but were not recognized well by renal or branchial receptors. Two 125 I-oPRL-binding sites were detected in every tissue tested. These binding sites are subject to physiological regulation since adaptation to seawater resulted in a significant decrease in specific binding

    72 hybrid tilapia were distributed into twelve tanks, each stocked in six fish (A, B, C, D, E, F) with different body size. The initial body weight was 62.69 +/- 1.46 g for fish A, 56.48 +/- 1.30 g for B, 50.75 +/- 1.19 g for C, 35.56 +/- 1.18 g for D, 31.05 +/- 0.88 g for E, and 27.35 +/- 0.95 g for F (mean +/- SE). The fish were reared under four ration levels (deprived of feed, fed at 1.5% body weight per day (BW.d-1), fed at 3.0% BW.d-1, or fed excess) throughout four weeks, respectively. The specific growth rate (SGR) and feed efficiency (FE) of the fish increased with increasing ration level up to 3.0% BW.d-1, and then, SGR maintained at a constant level while FE dropped with continuing increase of ration. The variance coefficient of SGR and final body weight was relatively high in the fish that fed at 1.5% BW.d-1. For fish A, SGR was not significantly different, between 1.5% BW.d-1, 3.0% BW.d-1 and fed excess, while in fish F, relatively high variations were found among different ration treatments. This experiment revealed that the growth and size hierarchy of hybrid tilapia were related to their ration level and initial body size. Under ration levels more than 3.0% BW.d-1, SGR was usually high, and size hierarchy was relatively weak.
