    Groups of St Peter's fish Sarotherodon galilaeus were trained during 28 days of classical conditioning to respond to an acoustic signal by approaching a feeder. Their ability to retain the acoustically conditioned behaviour was tested after eight different intervals ranging from 12 to 188 days from termination of training. Retention tests comprised 7 consecutive days of retraining and the fish response was compared with that of naive fish. Fish response drastically diminished with time. After 55 days, there was no apparent expression of memory on the first test day but fish response was restored on subsequent retraining days, indicating the existence of latent memory. Six months from the end of training, there was no indication of behavioural retention and the response completely vanished. The study was conducted in the context of sea ranching, with classical conditioning used to gain control over fish location. In light of the present results, it is suggested that periodic reinforcement of the acoustically conditioned behaviour should be used.

    Full Text Available The food analysis of 80 specimens of Oreochromis mossambicus collected from Borna Reservoir of Maharashtra, India revealed that the food of juveniles mainly consisted of rotifers (35%, followed by copepods (30%, Chlorophyceae (20%, Bacillariophyceae (10% and aquatic insects (5%. While the food items recorded in the gut of adults were Chlorophyceae (40%, followed by Bacillariophyceae (30%, rotifers (15%, copepods (10% and aquatic insects (5%. During present study it was found that the juveniles of O. mossamobicus mainly feed on zooplankton, and adults on phytoplankton. Intense feeding was noticed during summer season and juveniles were the active feeders.

    Full Text Available A stunted population of Oreochromis mossambicus occurs in the Matiovila Hot Sulphur Spring in the Kruger National Park. The growth of the fishes can best be described by the Von Bertalanffy equation L, = ^^(l-e0154^028^ mm SL. Breeding occurs throughout the year and the smallest sexually mature female was 35 mm SL. The fish from this locality were morphometrically compared to another stunted population and to a population of 0. mossambicus from a large impoundment. Speculative reasons for and advantages of stunting are presented.

  6. 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.

    2005-02-01

    Full Text Available In the present study an 8-week feeding trial was conducted on sex-reversed red tilapia (Oreochromis niloticus x O. mossambicus to assess the effects of diets containing various levels (i.e. 0, 50, 100, 500, 1,000 and 2,500 ppb of aflatoxin B1 (AFB1 on growth performance, blood parameters and histopathology of fish. Results showed that experimental fish fed AFB1 with 2,500 ppb showed significant reduced weight gain and hepatosomatic index. However, feed supplemented with AFB1 caused no effect on survival rate of the fish in each group. Feeding high level of AFB1 (1,000 and 2,500 ppb also affected some blood parameters i.e. hemoglobin and plasma protein. Some histopathological changes (i.e. cloudy swelling, inflammation and cell necrosis were observed in liver and pancreas of fish fed AFB1 with 1,000 and 2,500 ppb. The severity of symptoms was related with concentration of AFB1. This indicated that AFB1 may impair the functioning of fish hepatocytes. However, no residue of AFB1 was detected in fish tissues at completion of the feeding period. It can be concluded that fish feeds occasionally contaminated with AFB1 directly affected fish health but may have no negative impact on fish consumers.

    Oreochromis mossambicus (Peters 1852) (Tilapia) is one of the most consumed fish globally. Tilapia thrives well inenvironments 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, andstudied the prevalence of resistance genes bymolecularmethods. A total of 91 bacterial strains were obtained, which includefish 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) bla_{CTX-M}, bla_{SHV} and aac(6')-Ib-cr gene was 38%, 24%, 38%, 31% and 31% respectively. Forty-twopercent of the Enterobacteriaceae strains carried bla_{CTX-M} gene, which is a common ESBL gene in clinics. The studydemonstrates that tilapia found in the polluted waters can serve as reservoirs and an alternative route for human exposure toclinically important ARG-carrying bacteria. The consumption and handling of these fish may pose a potential health risk.

    2011-10-01

    Successful crossbreeding between Oreochromis niloticus and Sarotherodon melanotheron to produce a commercial hybrid has been difficult. The karyotypes and isoenzyme of these two species and their reciprocal hybrids (O. niloticus female × S. melanotheron male, S. melanotheron female × O. niloticus male, the last not included in the isoenzyme study) were investigated via metaphase chromosomes obtained from head kidney cells and electropherogram of lactate dehydrogenase (LDH) isoenzymes from the liver, kidney, white muscle, heart, and eye balls. The diploid chromosome number (2n=44) and the fundamental number (NF=50) of the four tilapia genotypes were the same. However, the karyotype of O. niloticus had three pairs of sub-metacentric (sm), twelve pairs of sub-telocentric (st), and seven pairs of telocentric (t) chromosomes, while S. melanotheron had one pair of metacentric (m), two pairs of sm, 12 pairs of st, and seven pairs of t chromosomes. The reciprocal hybrids both showed a mixed karyotype range between their parents: 0.5 pair of m, 2.5 pairs of sm, 12 pairs of st, and seven pairs of t chromosomes. In view of the electropherogram of isozymes, only the LDH of the kidney showed significant clear bands, with five bands in O. niloticus, three bands in S. melanotheron, and duplicated six bands in the hybrids. The bands varied depending on their activities and mobilities. We considered that the differences in karyotype and isoenzyme were related to the genetic mechanism for post-mating isolation, and provided some additional basic genetic background of their taxonomy.

    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.

    The research and publications of Peter Ladefoged and his students have been a strong influence in elevating the field of phonetics to a science, and in bringing together phonetics and phonology. I will cite some examples of how Peter's work and that of his colleagues has influenced the research of many of us at MIT and around the world, where attempts to develop unifying theories often need to undergo continuous revision based on the meticulous articulatory and acoustic data that he reports in his books and other publications. These include his descriptions of the involvement of the tongue root in vowel systems, the fricatives of Mandarin Chinese, the inventory of places of articulation he catalogs in the languages of the world, and the many uses of laryngeal states in providing phonological contrasts.

    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.

    2003-01-01

    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 ...

    Full Text Available Optimal chromosome preparations were obtained from stimulated lymphocyte cultures with a new method based on a combination and modification of several techniques. Tilapia rendalli, T. sparrmanii and Oreochromis mossambicus have somatic chromosome numbers of 44, 42 and 44, respectively. Chromosome pairs L1 and L2 are easily identified in all the karyotypes and distinctive of the tilapias. Tilapia sparrmanii has one additional large metacentric chromosome pair(L3, which occurs concurrently with the reduction of two in the total chromosome number. The F chromosomes were divided into two groups, viz a submetacentric (sm and a telocentric (t group. T. rendalli has 8 sm chromosomes, while both T. sparrmanii and O. mossambicus have 6 chromosomes in the sm group. The rest of the F chromosomes were telocentric. The identification of the sex chromosomes in the karyotypes of tilapia has thus far not been possible using standard techniques.

  16. Salinity Tolerance and Growth Response of Juvenile Oreochromis mossambicus at Different Salinity Levels

    2004-01-01

    Juveniles of Oreochromis mossambicus with initial wet weights of 0.0382±0.0859 g and initial total lengths of 0.735±1.425 cm were tested for their salinity tolerance. The juveniles were subjected to five salinity levels for a period of seventy-five days. These salinity levels correspond to the salinities found along the creek and in estuarine regions. Each set of experiments was conducted at a fifteen day intervals. The weight, length and survival rate were calculated. No mortality was observed at salinity levels 0, 5, 10 and 15, while the juveniles faced slight mortality at 20 in the same environmental conditions, including the diet. There was no significant difference in specific growth rate at all salinity levels. The juveniles of O.mossambicus could survive up to 20 salinity. These results suggest that this species can grow and be exploited commercially in brackish waters, rivers and estuarine regions.

    Peters anomaly is a rare dramatic finding at birth and can be associated with other systemic malformations. We performed a literature review of multiple case reports and case series to better define the common characteristics and unusual findings associated with Peters anomaly. A representative case is discussed followed by a literature review of multiple case reports and case series. The literature search was conducted for the years 1969 to 2009. Cases and case series were included in the review of published English ophthalmic literature. Cases were excluded if no information was reported on ocular and systemic malformations or if no information was reported on surgical interventions or outcomes. In addition, if cases did not report laterality of the lesion, they were excluded from the review. Fifty-eight cases were found that fit the above criteria, and the relevant cases were reviewed to better characterize the systemic malformations, interventions, and outcomes associated with Peters anomaly reported in the literature. Fifty-eight cases of Peters anomaly were reviewed. Of those cases reporting sex, 56% were men and 44% of cases were women. In terms of laterality, 67.2% of cases were bilateral versus 32.8% of cases that were unilateral. Moreover, bilateral cases of Peters anomaly were associated with a higher rate of systemic malformations (71.8%) versus unilateral Peters anomaly (36.8%). This difference was significant (P anomaly type I (87.5%), as opposed to those patients with Peters anomaly type II (14.2%) (P anomaly are presented. Cornea specialists who care for pediatric patients should be aware of the common and uncommon associations with Peters anomaly. Although bilateral Peters anomaly is much more commonly associated with systemic malformations, we believe that all patients with Peters anomaly should be screened for systemic malformations by both pediatricians and geneticists and undergo chromosomal analysis and molecular genetic testing.

    Noga, E J; Wright, J F; Pasarell, L

    1990-04-01

    Adult, aquarium-reared Oreochromis mossambicus (Tilapia mossambica), which were naturally infected with Mycobacterium marinum, displayed non-healing skin ulcers and other clinical signs considered to be typical of piscine mycobacteriosis. However, in addition, they frequently had melanotic foci in the skin and spleen, due to the presence of pigment cells surrounding the cutaneous and splenic inflammation. Such melanotic foci have never been reported in response to mycobacteriosis. All fish also have variable numbers of melanomacrophages which appeared to replace pancreatic acini. The relationship of the pancreatic melanomacrophages to the pathogenesis of mycobacteriosis is uncertain, but such lesions may have contributed to the chronic cachexia associated with this case.

    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.

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

    Previous research has shown that sublethal concentrations of cadmium, naphthalene and dichlorvos (DDVP) decreased growth rates in bream and Mozambique tilapia. One of the factors known to affect fish growth is the activity of gut digestive enzymes such as of lipases, proteases, carbohydrases. We assumed that toxicant-induced inhibition of the digestive enzyme activity and, consequently, the impaired digestion of food may contribute to the reduction of growth in fish exposed to toxicants. However, the influence of toxicants on digestive enzyme activities is poorly studied. The contribution of toxicant-induced changes of digestive enzymes activity to growth rate retardation in exposed fish remains unknown. The goal of this study was to examine the influence of an organophosphorus insecticide DDVP, a polyaromatic hydrocarbon naphthalene, and a metal cadmium on fish gut carbohydrase (CH) activity. 14 refs., 2 tabs.

    To evaluate the potential environmental effects of engineered nano metals,it is important to determine the adverse effects of various nanomaterials on aquatic species.Adult tilapia (Oreochromis mossambicus) were maintained in 10 L glass aquaria,and exposed to a graded series of synthesized silver nanoparticles (Ag-NPs) at 25,50 and 75 mg/L for eight days.The LC50 value was 12.6 mg/L.Reduced activities of antioxidant enzymes and the contents of antioxidants were lowered in the gills and liver of fishes treated with Ag-NPs,which resulted in heavy accumulation of free radicals.Histopathological results imply that the balance between the oxidative and antioxidant system in the fish was broken down during Ag-NPs exposure.The principal coneern related with the release of nanomaterials and their smaller particle may change the materials transport and potential toxicity to aquatic organisms compared to larger particles.

    Black tilapia (Oreochromis mossambicus) fish wastes (scales) were evaluated for its suitability as sources of gelatin. 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.

    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.

    The effect of exposure to sublethal concentrations (0.017 mg L(-1), 1/10 of LC50) of the novel organophosphate (OP) insecticide, 2-butenoic acid-3-(diethoxyphosphinothioyl) methyl ester (RPR-II) on biochemical parameters in Oreochromis mossambicus was studied during exposure for 3, 7, 15, 30 and its recovery response after seven days. Acetylcholinesterase (AChE) activity of brain, gill and muscle was inhibited by 67%, 77% and 73% respectively on day-30. The plasma and kidney alanine aminotransferase (AlaAT), and aspartate aminotransferase (AspAT) activity increased, while decreases were observed in gill and liver. Increases in acid phosphatase (AcP), and alkaline phosphatase (AP) activities were observed in plasma, gill, and kidney, and reductions of 20% and 61% in liver AcP and AP, respectively. Depletion of glycogen was observed in all tissues, an indication of typical stress related response of the fish with pesticide. Lactate dehydrogenase (LDH) activity decreased in liver and muscle, indicating tissue damage but a significant increase in LDH activity in gill and brain was observed. Depletion of glutathione (GSH) was observed in all tissues, thereby enhancing lipid peroxidation resulting in cell damage. The induction in hepatic glutathione-S-transferase (GST) levels indicates protection against the toxicity of xenobiotic-induced lipid peroxidation. There was a significant recovery in the above biochemical parameters, in all tissues of fish after a recovery period of seven days. These results revealed that the OP insecticide RPR-II is highly toxic and affects the intermediary metabolism of O. mossambicus.

    In allopatric speciation species differentiation generally results from different selective pressures in different environments, and identifying the traits responsible helps to understand the isolation mechanism(s) involved. 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.

    There is growing evidence that climate change has greatly altered environmental conditions in many aquatic ecosystems over the last decades, leading to changes in fish distribution and life history traits. Recent works conducted in Senegalese and Gambian coastal marine, estuarine and freshwater ecosystems have shown important changes in the intensity, frequency and breeding timing of wild population of Sarotherodon melanotheron in response to changes in salinity regimes. In addition to salinity, this study investigates the potential influences of other environmental factors that have received less attention on the reproduction of S. melanotheron from three different aquatic ecosystems in Senegal. The results demonstrate that day-length and temperature affect sexual maturity in both males and females from Guiers Lake and Hann Bay, but no such effects were found in upstream of the Saloum Estuary, where the spawning activity seems to be under the synergetic control of rainfall and salinity that apparently predominate over all the other ambient factors. This study demonstrated for the first time that aside from photoperiod and temperature, rainfall also influences fish reproduction in Hann Bay probably through its effects on water quality. Furthermore, our results confirm previous findings that changes in salinity regimes resulting from seasonal variations in precipitation and evaporation are the ultimate causes of temporal changes in the reproductive activity of the species in this estuary.

    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.

    Full Text Available The black-chinned tilapia Sarotherodon melanotheron heudelotii Rüppell 1852 (Teleostei, Cichlidae displays remarkable acclimation capacities. When exposed to drastic changes of salinity, which can be the case in its natural habitat, it develops quick physiological responses and keeps reproducing. The present study focused on the physiological impact of salinity on male reproductive capacities, using gene expression as a proxy of acclimation process. Two series of experimental fish were investigated: the first one was composed of fish maintained in freshwater for several generations and newly acclimated to salinities of 35 and 70, whereas the second one consisted of the descendants of the latter born and were raised under their native salinity. Expression patterns of 43 candidate genes previously identified from the testes of wild males was investigated in the three salinities and two generations. Twenty of them showed significant expression differences between salinities, and their predicted function revealed that most of them are involved in the osmotic tolerance of sperm cells and/or in the maintenance of sperm motility. A high level of expression variation was evidenced, especially for fish maintained in freshwater. In spite of this, gene expression patterns allowed the differentiation between fish raised in freshwater and those maintained in hypersaline water in both generations. Altogether, the results presented here suggest that this high variability of expression is likely to ensure the reproductive success of this species under varying salinities.

    The effect of salinity was studied in natural populations of the black-chinned tilapia (Sarotherodon melanotheron) from West Africa. This euryhaline species colonizes nearly all coastal environments from bays to lagoons characterized by salinities ranging from fresh water to hypersaline water over 100 ‰. Individuals were sampled during the dry season at several locations characterized by different levels of salinity (3-102 ‰). Their osmotic status and their gills were analyzed. The branchial mitochondria-rich cells (MRC), localized at the basis of the filaments and along the lamellae in fish taken from the saline stations, showed a wide plasticity with significant differences in their number and size. The most striking results were a significant larger area (≈3x) and a higher number (≈55x) of MRC at high salinity (102 ‰) compared to low salinity (3 ‰). The major ion transporters and channels were localized by immunocytochemistry and different expression patterns have been recorded between stations. Despite an increased Na⁺/K⁺-ATPase (NKA) α-subunit expression and NKA activity, pointing to an increased monovalent ion excretion, a severe osmotic imbalance was recorded in animals living in hypersaline environments.

    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.

    The diet of the harvester termite Hodotermes mossambicus was investigated at two sites with distinct dietary components: C4 grasses (δ13 C isotope values, -13.8‰to -14.0‰) and C3 plants (δ13C isotope values, -25.6‰ to -27.1‰). By comparing observations of food items carried into the colony by the termites and carbon isotope ratios of whole termites (that determined assimilated carbon), the relative proportion of the C3 and C4 plant food components of the termite diet was estimated. There was agreement between the observational data and stable carbon isotopic data, with grass representing approximately 93% of the diet of H, mossambicus at two study sites (urban and rural) on the South African highveld. However, when correcting for mass of food items, that is, C3 and C4, carried by termites, the proportion of grass (C4) in the diet may be underestimated.

    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.

    Full Text Available Aim: The present study aims to evaluate the morphometric parameters and level of Salmonella and Escherichia coli contamination of Tilapia guineensis and Sarotherodon melanotheron in the waterway of Southern Benin. Materials and Methods: 183 T. guineensis and 195 S. melanotheron were collected from June to July 2014 in four waterways: Lake Ahémé, Nokoué Lake, coastal lagoon, and lagoon of Porto-Novo. Weight, total length, and standard length of these fish were evaluated. E. coli and Salmonella sp. were sought in fresh fish. Results: The results obtained in this study indicate that S. melanotheron presented high-performance of length and weight more than T. guineensis in Ahémé Lake and lagoon of Porto-Novo. However, in Nokoué Lake and coastal lagoon, no difference was observed between the two species of fish. As for bacteriological analysis, the population of T. guineensis was more contaminated with E. coli with respective values of 60% and 59.52% in the Nokoué Lake and coastal lagoon than in the two other streams. Regarding the population of S. melanotheron, she was most contaminated in the coastal lagoon with a percentage of 66.66% in Ahémé Lake, Nokoué Lake, and the lagoon of Porto-Novo. However, no Salmonella germ was detected in fish analyzed in this study. Conclusion: It appears that the morphometric parameters and weight of T. guineensis are lower than those of S. melanotheron. The evaluation of the microbiological quality revealed that T. guineensis is more contaminated with E. coli that S. melanotheron.

A total of 89 fish (57 males and 32 females) was collected from Awba Dam and 95 fish (48 males and 47 females) from the reference site. In general, fish sampled from Awba Dam were bigger than reference site. Sediment samples were also collected from both sites for contaminant analysis. Expression of ppar and cyp1 isoforms was analyzed using validated real-time PCR, while CYP1A and PPAR protein levels were analyzed using immunochemical method with specific antibodies. CYP-mediated catalytic responses (EROD, MROD and BROD) were performed by biochemical methods. We observed significant increases in ppar and cyp1 isoforms mRNA in both male and female fish from Awba Dam, compared to the reference site. Catalytic activities of EROD, MROD and BROD paralleled cyp1 transcript levels. Sex-related differences in PPAR and CYP1A protein levels were also observed, showing higher CYP1A proteins in males, compared with females, and higher PPAR proteins in females compared with males. Principal component analysis (PCA) biplot showed positive relationships between biological responses (ppar isoforms), condition factor (CF) and sediment PCBs, PAHs, OCPs and heavy metal concentrations. The present study shows that S. melanotheron inhabiting Awba Dam are severely affected by different classes of environmental contaminants that target metabolic processes (PPAR) and biotransformation pathways (CYP1A) in male and female fish, compared to a reference site. Interestingly, fish from Awba Dam were exhibiting good growth (evidence by high CF values) that paralleled increases in the transcriptional activation of ppar and cyp1 isoforms, despite the high

    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.

    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.

    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.

    Radiotracer techniques were used to measure influx and efflux rates of CaS in freshwater-adapted Oreochromis mossambicus. The influx rate of CaS is related to body weight (W) as Fin = 50W0.805 nmol CaS /h. For a 20-g fish the calculated influx rate was 558 nmol CaS /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 CaS /h. The CaS efflux rate was calculated using the initial rate of appearance of radiotracer in the ambient water and the specific activity of plasma CaS . 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 CaS is related to body weight as Fout = 30W0.563 nmol CaS /h, which means an efflux rate of 162 nmol CaS /h for a 20-g fish. The net whole-body CaS 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 CaS .

    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

    In 1636, the Rostock professor of medicine and the art of poetry, Peter Lauremberg (1585-1639), was one of the earliest to mention circulation which had been discovered by William Harvey and documented in his anatomical manual. In 1628 William Harvey proved the existence of the blood circulation by calculating the "cardiac output in a half an hour (semihora)". The answer to the question why Harvey chose half an hour as the time range can be found in the way of measuring time usual at that period. The sandglasses were turned half-hourly in maritime navigation and the wheel-clocks on shore had only the hour-hand. Improved chronometry was one of the prerequisites for measuring cardiac output. The minute-hand became usual after 1700 and the second-hand later on. Taking into consideration the alterations of cardiac output made the latter one of the most important circulation parameters in diagnostics, prognostication and therapeutics.

  14. Rehabilitation: disability ethics versus Peter Singer.

    Science.gov (United States)

    McPherson, Gary W; Sobsey, Dick

    2003-08-01

    This commentary discusses utilitarian bioethics currently articulated by Peter Singer, one of the most widely known bioethicists of the 21st century. His controversial concepts of personhood and replaceability have important implications for people with disabilities, caregivers, and rehabilitation in general. Singer suggests that people with severe disabilities should not be considered persons and therefore have no rights or status in ethical issues. In addition, he argues that, although some people with less severe disabilities qualify as persons, their potential quality of life is significantly compromised by disability and therefore it may be ethically desirable to eliminate them so that their resources can be used for someone with superior potential. We reject these ideas, and suggest that those involved in rehabilitation carefully consider these ideas because they imply that rehabilitation is an immoral act unless it results in full and typical function.

This book, part of a four-volume series planned to deal with all aspects of a standard NMR experiment, is almost the exact book I have been hoping to find. My department has acquired, as have hundreds of other undergraduate institutions, high-field NMR instrumentation and the capability of doing extremely sophisticated experiments. However, the training is often a one- or two-day experience in which the material retained by the faculty trained is garbled and filled with holes, not unlike the information our students seem to retain. This text, and the accompanying exercises based on data contained on a CD-ROM, goes a long way to fill in the gaps and clarify misunderstandings about NMR processing.

    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

  19. The Social Dynamics of the Peter Principle

    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.

  20. Tilapia (Oreochromis mossambicus) brain cells respond to hyperosmotic challenge by inducing myo-inositol biosynthesis.

    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.

    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.

    The ability to adjust skin darkness to the background is a common phenomenon in fish. The hormone alpha-melanophore-stimulating hormone (alphaMSH) enhances skin darkening. In Mozambique tilapia, Oreochromis mossambicus L., alphaMSH acts as a corticotropic hormone during adaptation to water with a low pH, in addition to its role in skin colouration. In the current study, we investigated the responses of this fish to these two environmental challenges when it is exposed to both simultaneously. The skin darkening of tilapia on a black background and the lightening on grey and white backgrounds are compromised in water with a low pH, indicating that the two vastly different processes both rely on alphaMSH-regulatory mechanisms. If the water is acidified after 25 days of undisturbed background adaptation, fish showed a transient pigmentation change but recovered after two days and continued the adaptation of their skin darkness to match the background. Black backgrounds are experienced by tilapia as more stressful than grey or white backgrounds both in neutral and in low pH water. A decrease of water pH from 7.8 to 4.5 applied over a two-day period was not experienced as stressful when combined with background adaptation, based on unchanged plasma pH and plasma alphaMSH, and Na levels. However, when water pH was lowered after 25 days of undisturbed background adaptation, particularly alphaMSH levels increased chronically. In these fish, plasma pH and Na levels had decreased, indicating a reduced capacity to maintain ion-homeostasis, implicating that the fish indeed experience stress. We conclude that simultaneous exposure to these two types of stressor has a lower impact on the physiology of tilapia than subsequent exposure to the stressors.

    Full Text Available Qualitative and quantitative histological alteration was taken to analyze in fish Oreochromis mossambicus collected from Kedilam River at three stations, which receive mostly industrial effluent and municipal runoff. Histoarchitecture of tissue alteration and percentage of prevalence was used as protocol for analysis. Results showed that number of histological alteration observed in gill like structural alteration of epithelium, epithelial lifting, fusion of secondary lamellae and hyperplasia. In liver blood congestion, regressive changes like degeneration of hepatocytes, vacuolation, and necrosis observed where as in kidney it shows glomerular congestion, tubular degeneration, progressive changes like hypertrophied epithelial cells, haemorrhage in bowman’s space. Among the three stations severe histological alteration and percentage prevalence was observed in order of station 1> station 2 >station 3. Highest histological alteration and percentage of prevalence in three organs of fish o. mossambicus are kidney >gill >liver. The major reason for this histological alteration and contamination of fish is mostly due to industrial effluent. Repeated and continuous monitoring is must needed to protect the aquatic organism.

    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.

    Abstract (E:

    In the books of Peter Downsbrough photography occupies a central place. Oscillating between documentation and art, the photographic image connects the space-time of the book with the reality of the depicted urban space. Taking Deleuze and Guattari’s concept of the frame as a starting point, the article analyzes how Downsbrough relates the architecture of the book to the architectonic space of the city as well as to the narrative structure of film. As a significant element of the book, photography functions as an agent between the different medias, which the artist uses such as sculpture, book, film, and language.

  7. Peter Redpath’s Philosophy of History

    Directory of Open Access Journals (Sweden)

    Curtis L. Hancock

    2016-03-01

    Full Text Available Peter Redpath is a distinguished historian of philosophy. He believes that the best way to acquire a philosophical education is through the study of philosophy’s history. Because he is convinced that ideas have consequences, he holds that the history of philosophy illuminates important events in history. Philosophy is a necessary condition for sound education, which, in turn, is a necessary condition for cultural and political leadership. Hence, the way educators and leaders shape culture reflects the effects of philosophy on culture. In light of this background, it is possible to discern in Redpath’s account of the history of philosophy a corresponding philosophy of history. This emerges as he explains how philosophers have produced changes in thinking that have profound consequences for the culture at large. Some of these changes, many of them significant, have been positive, but others have been disastrous. Much of Redpath’s philosophy of history diagnoses what went wrong in the history of philosophy so as to indicate why modern culture suffers considerable disorder. The good news is that Redpath’s philosophy of history prescribes ways to correct Western Civilization’s current malaise.

  8. 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.

    Asymmetry analysis was carried out for three bilateral characters of two cichlid fish species, Sarotherodon melanotheron and Coptodon guineensis collected from two localities, Lake Ahémé and Porto-Novo lagoon, Republic of Bénin, West Africa. For both S. melanotheron and C. guineensis snout length (SL), eye diameter (ED) and number of scales on lateral line (LLS), bilateral asymmetry was higher in the fish specimens collected from Porto-Novo lagoon compared with that of specimens from Lake Ahémé. Bilateral asymmetry in S. melanotheron and C. guineensis increased with the fish size at all localities. The possible causes of bilateral asymmetry in the two cichlid species are discussed in relation to different pollutants in both water bodies.

    Endomorphins are tetrapeptides involved in pain and neuroendocrine responses with high affinity for mu opioid receptors in mammals. In the present investigation, we studied the distribution of endomorphin-like-immunoreactive (EM-L-ir) neurones in the brain of the cichlid fish Oreochromis mossambicus. Application of antisera against endomorphin 1 and 2 (EM-1-2) revealed the presence of EM-L-ir somata and fibres throughout the different subdivisions of the olfactory bulb such as the olfactory nerve layer and the granule cell layer. While the extensions of EM-L-ir fibres were seen along the medial olfactory tract, intensely labeled EM-L-ir somata were found in different subdivisions of the telencephalon. In the diencephalon, intensely stained EM-L-ir neurones were noticed in the preoptic area, the nucleus preopticus pars magnocellularis, the suprachiasmatic nucleus, the nucleus lateralis tuberis pars lateralis (NLTl) and the nucleus lateralis tuberis pars medialis (NLTm) regions, whereas projections of EM-L-ir fibres were also seen along the hypothalamo-hypophyseal tract suggested a possible hypophysiotrophic role for these neurones. Intense to moderately stained EM-L-ir neurones were noticed in different subdivisions of thalamic nucleus such as the dorsal posterior thalamic nucleus, commissura posterior, ventromedial thalamic nucleus, nucleus posterior tuberis, ventrolateral thalamic nucleus and medial preglomerular nucleus. Numerous intensely stained perikarya and axonal fibres were also noticed throughout the inferior lobe, along the periventricular margin of the reccessus lateralis, and in the nucleus recesus lateralis regions. In addition, numerous moderately labeled EM-like neuronal populations were found in the secondary gustatory nucleus and rostral spinal cord. The widespread distribution of EM-L-ir neurones throughout the brain and spinal cord indicate diverse roles for these cells in neuroendocrine and neuromodulatory responses for the first time in fish

    Young fish (Oreochromis mossambicus) were exposed to microgravity (micro g) for 9 to 10 days during space missions STS-55 and STS-84, or to hypergravity (hg) for 9 days. Young animals (stages 11-12), which had not yet developed the roll-induced static vestibuloocular reflex (rVOR) at micro g- and hg-onset, and older ones (stages 14-16), which had already developed the rVOR, were used. For several weeks afterwards, the rVOR was recorded after termination of mug and hg. Here are the main results: (1) In the stage 11-12 fish, the rVOR gain (response angle/roll angle) measured for roll angles 15 degrees, 30 degrees, and 45 degrees was not affected by microgravity if animals were rolled from the horizontal to the inclined posture, but was increased significantly if animals were rolled in the opposite manner. The rVOR amplitude (maximal eye movement during a complete 360 degrees roll) of micro g animals increased significantly by 25% compared to 1g controls during the first postflight week, but decreased to the control level during the second postflight week. Microgravity had no effect in stage 14-16 fish on either rVOR gain or amplitude. (2) After 3g exposure, both rVOR gain and amplitude were significantly reduced for both stage 11-12 and stage 15 fish. One g readaptation was completed during the second post-3g week. Hypergravity at 2 or 2.5 g had no effect. (3) Hypergravity at all three levels tested (2g, 2.5g, and 3g) accelerated the morphological development as assessed by external morphological markers. Exposure to micro g- or 3g-periods during an early developmental period modifies the physiological properties of the neuronal network underlying the static rVOR; in susceptible developmental stages, these modifications include sensitization by microgravity and desensitization by hypergravity.

  1. Laparoscopic cholecystectomy and the Peter Pan syndrome.

    Orlando, G; Bellini, P; Borioni, R; Pace, A

    2000-08-01

    We report the case of a patient who experienced hemobilia a few weeks after undergoing laparoscopic cholecystectomy (LC). This condition was due to the rupture of a pseudo-aneurysm of the right hepatic artery in the common bile duct, probably caused by a clip erroneously fired during LC on the lateral right wall of the vessel. It also caused the formation of multiple liver abscesses and the onset of sepsis. This life-threatening complication led to melena, fever, epigastric pain, pancreatitis, liver dysfunction, and severe anemia, requiring urgent hospitalization and operation. In the operating theater, the fistula was closed, the liver abscesses drained, and a Kehr tube inserted. Thereafter, the patient's general condition improved, and she is now well. LC is often considered to be the gold standard for the management of symptomatic cholelithiasis. However, recent data have undermined that opinion. The apparent advantages offered by LC in the short term (less pain, speedier recovery, shorter hospital stay, and lower costs) have been overwhelmed by the complications that occur during long-term follow-up. When the late downward trend in the bile duct and the vascular injury rate are taken into consideration, the learning curve is prolonged. Therefore, LC should be regarded as the surgical equivalent of a modern Peter Pan-i.e., it is like a young adult who should make definitive steps toward becoming an adult but does not succeed in doing so. We report the case of a patient who experienced hemobilia a few weeks after undergoing laparoscopic cholecystectomy. Based on the facts in this case, we argue that the endoscopic procedure still needs to be perfected and cannot yet be considered the gold standard for selected cases of gallstone disease.

    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 C1 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.

    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.

    2009-12-01

    In this paper, Britten's opera Peter Grimes (1945) is used as an illustrative case study through which to examine the depiction of psychiatric disorders in opera. It is argued that Peter Grimes is a powerful example of how opera, in the hands of a great composer, can become an invaluable tool for examining subjective human experience. After a brief discussion of opera as a vehicle to express emotions, various operas are drawn upon to provide a historical perspective and to demonstrate the long interconnection existing between opera and madness. An in-depth analysis of Peter Grimes, its background and central character, is then provided, in order to demonstrate how opera can elicit empathy for individuals affected by mental health problems.

As one of the earliest witnesses to this constellation and its symbolization of community leaders as elders-pastors-overseers, the text of 1 Peter 5:1-5a deserves more attention than it has hitherto been accorded in the study of early Christian ministry and church order.

    Full Text Available Black tilapia (Oreochromis mossambicus skin gelatin was potential material for edible film formation. However, it needs some modifications to improve the mechanical and barier properties. One of modification is by adding a cross linking agent. Seaweed extract Kappaphycus alvarezii containing phenol compounds was oxidized to be converted into quinone. It was expected to act as a cross linking agent. The purpose of this study was to determine the characteristics of edible film from black tilapia skin gelatin by adding with oxidized K. alvarezii extract. Edible film was made by addition of K. alvarezii extract (E at concentration of 0%(E0; 2%(E1; 4%(E2; 6%(E3; 8%(E4 (v/w for each gelatin concentratios (G were 3g(G1; 6g(G2; 9g(G3; 12g(G4 into 150 ml destilled water containing 10% glycerol (w/w of gelatin. Gelatin film solution was agitated at 50oC for 30 min and dehydrated in a cabinet dryer at 50oC. The addition of oxidized K. alvarezii extract increased tensile Strength (TS and elongation at break properties. The highest TS was 3.08 MPa, shown by G4E1. The lowest water vapor permeability (WVP was ontained by G4E1 (0.01 x 10-10 g. H2O/m.s.Pa.

    This work analyzed spatially potential carcinogenic risks associated with ingesting arsenic (As) contents in aquacultural tilapia (Oreochromis mossambicus) in coastal regions of southwestern Taiwan, where the blackfoot disease prevails. Sequential indicator simulation (SIS) was used to reproduce As exposure distributions in groundwater based on their three-dimensional variability. A target cancer risk (TR) associated with ingesting As in aquacultural tilapia was calculated to evaluate the potential risk to human health. Owing to sparse measured data, Monte Carlo simulation and SIS properly accounted for the uncertainty of assessed parameters. The probabilistic risk assessment formulated suitable strategies under various remedial stages. Aquacultural regions with high risks were mapped to elucidate the safety of groundwater use at different depths. Many TRs determined from the risks at the 75th and 95th percentiles exceed one millionth in the regions, indicating that ingesting tilapia farmed in the highly As-polluted regions poses potential cancer threats to human health. The 75th percentile of TR is considered in formulating a remedial strategy for the aquacultural use of groundwater in the preliminary stage. Additionally, this study suggests reducing the use of groundwater in aquaculture or changing the depths from which groundwater is withdrawn in the areas with high risks of cancer.

    Endosulfan is one of the most hazardous organochlorines pesticides responsible for environmental pollution, as it is very persistent and shows bio-magnification. This study evaluated the impact of acute endosulfan toxicity on metabolic enzymes, lysozyme activities, heat shock protein (Hsp) 70 expression, and histopathology in Tilapia (Oreochromis mossambicus). Among the indicators that were induced in dose dependent manner were the enzymes of amino acid metabolism (serum alanine aminotransferase and aspartate aminotransferase), carbohydrate metabolism (serum lactate dehydrogenase), pentose phosphate pathway (Glucose-6-phosphate dehydrogenase) as well as lysozyme and Hsp70 in liver and gill, while liver and gill Isocitrate dehydrogenase (TCA cycle enzyme) and marker of general energetics (Total adenosine triphosphatase) were inhibited. Histopathological alterations in gill were clubbing of secondary gill lamellae, marked hyperplasia, complete loss of secondary lamellae and atrophy of primary gill filaments. Whereas in liver, swollen hepatocyte, and degeneration with loss of cellular boundaries were distinctly noticed. Overall results clearly demonstrated the unbalanced metabolism and damage of the vital organs like liver and gill in Tilapia due to acute endosulfan exposure.

    2013-09-01

    Full Text Available Background: Cases of cataract surgery without penetrating keratoplasty in patients with Peters' anomaly are very rare. We report a case of Peters' anomaly type 2 with tilted lens due to synechia between the lens and iris that was treated with cataract surgery without penetrating keratoplasty. Case Presentation: A 16-year-old girl had Peters' anomaly in both eyes. Corneal opacity was severe in the left eye due to high-grade dysgenesis of the anterior segment. In the right eye, corneal opacity had spread from the center of the cornea to the inferotemporal side, and there was synechia between the iris and corneal endothelium from the inferonasal side to the inferotemporal side. Opacity was observed in the anterior pole of the lens, and there was synechia between the anterior iris and the lens. Ultrasound biomicroscopy (UBM revealed that the lens was tilted because of synechia. The tilted lens induced astigmatism, which reduced visual acuity to 20/250, in conjunction with a cataract. Cataract surgery was performed; the synechia between the lens capsule and the iris was severed, an intraocular lens was inserted, and the tilt was repaired. UBM was used postoperatively to confirm that the lens capsule synechia had been corrected and that the intraocular lens was not tilted. As a result, visual acuity improved to 20/100; glaucoma and expansion of corneal opacity were not observed. Conclusions: Severing of the synechia between the cataract and iris, during cataract surgery, in a patient with Peters' anomaly type 2 resulted in favorable postoperative visual acuity.

  8. Performance evaluation of chicken, cow and pig manure in the production of natural fish food in aquadams stocked with Oreochromis mossambicus

    Science.gov (United States)

    Rapatsa, M. M.; Moyo, N. A. G.

    The main objective of this study was to characterize the ecological conditions that prevail after the application of chicken, cow and pig manure. Three treatments, chicken, cow, pig manure and a control were assigned to aquadams in a completely randomized design and each treatment was replicated three times. The aquadams were fertilized 2 weeks before the fish were stocked. One hundred Oreochromis mossambicus (mean weight ±40 g) were stocked in each aquadam. Water physico-chemical parameters (temperature, dissolved oxygen, pH, electrical conductivity, salinity, turbidity, ammonia, nitrite, total alkalinity as calcium carbonate, and phosphorus) were determined once a week for the duration of the experiment. Zooplankton and phytoplankton in the different treatments were enumerated once every 2 weeks. The relationship between phytoplankton communities and the water physico-chemical parameters were evaluated using canonical correspondence analysis (CCA). The CCA indicated that the physico-chemical variables which best explain the distribution of phytoplankton were carbonate alkalinity, pH, phosphate, potassium, nitrogen and dissolved oxygen. Phytoplankton abundance was highest in chicken manure because the optimum nutrient conditions for the growth of phytoplankton were found in this treatment. Zooplankton abundance was also highest in the chicken manure treatment. The control was associated with one phytoplankton taxa, Chlorella. The numerical contribution of the different food items in the stomachs of O. mossambicus was determined. The diet of O. mossambicus was dominated by phytoplankton particularly Microcystis species. Total coliforms and Escherichia coli were used to assess the microbiological quality of the water in the different manure treatments. Chicken manure had the lowest total coliform and E. coli count. However, chicken manure had the highest Bacillus count. The implications of the microbial load in the chicken, cow and pig manure are discussed.

    The peptide transporter (PepT) systems are well-known for their importance to protein absorption in all vertebrate species. These symporters use H+ gradient at the apical membrane of the intestinal epithelial cells to mediate the absorption of small peptides. In fish, the intestine is a multifunctional organ, involved in osmoregulation, acid-base regulation, and nutrient absorption. Therefore, we expected environmental stimuli to affect peptide absorption. We examined the effect of three environmental factors; salinity, pH and feeding, on the expression, activity and localization of three PepT transporters (PepT1a, PepT1b, PepT2) along the intestine of the Mozambique tilapia (Oreochromis mossambicus). Quantitative real time PCR (qPCR) analysis demonstrated that the two PepT1 variants are typical to the proximal intestinal section while PepT2 is typical to the distal intestinal sections. Immunofluorescence analysis with custom-made antibodies supported the qPCR results, localized both transporters on the apical membrane of enterocytes and provided the first evidence for the participation of PepT2 in nutrient absorption. This first description of segment-specific expression and localization points to a complementary role of the different peptide transporters, corresponding to the changes in nutrient availability along the intestine. Both gene expression and absorption activity assays showed that an increase in water salinity shifted the localization of the PepT genes transcription and activity down along the intestinal tract. Additionally, an unexpected pH effect was found on the absorption of small peptides, with increased activity at higher pH levels. This work emphasizes the relationships between different functions of the fish intestine and how they are affected by environmental conditions. PMID:28167916

    Pesticides are contaminants of aquatic environments. Such ecosystems in the Western Cape, South Africa are at risk as most organophosphates are highly toxic to fish and other aquatic organisms. The objective of this experimental study was firstly to determine the acute toxicity of azinphos-methyl (AZP) to juvenile fish (Oreochromis mossambicus) and, secondly, to investigate the effects of repeated exposure of fish to an array of sublethal concentrations on morphological parameters such as growth, condition factor and organ-somatic indices. Food consumption and feeding response time were investigated as ecologically relevant behavioral endpoints which could affect growth, reproduction and survival and subsequently causes impacts at the population and/or community level. Finally, acetylcholinesterase (AChE) was used as biomarker to investigate effects at sub-organismal level following sequential exposure to AZP. The aim was to determine how sequential spraying procedures, using different exposure concentrations and intervals, affected fish as reflected by their responses at different organizational levels. A dose-dependent effect on feeding impairment was observed in the feeding response experiment. The correlation found between growth impairment, feeding activity and AChE inhibition therefore indicates that frequency of exposure can play an important role regarding the severity of impacts to non-target organisms. This study provides evidence that AZP has harmful effects on non-target aquatic organisms, such as fish which can be manifested in the early developmental stages. Sequential exposures showed that dosage and frequency of spraying and spraying interval could exacerbate harmful effects. AChE inhibition and organosomatic indices can be used effectively to measure effects. Copyright © 2013 Elsevier B.V. All rights reserved.

  12. Evidence for the involvement of dopamine in stress-induced suppression of reproduction in the cichlid fish Oreochromis mossambicus.

    In the present study, we examined whether stress-induced suppression of reproduction is mediated through the catecholaminergic neurotransmitter dopamine (DA) in the female cichlid fish Oreochromis mossambicus. In the first experiment, application of antibody against tyrosine hydroxylase (TH; a marker for DA) in brain sections revealed the presence of intensely stained TH immunoreactive cells in the preoptic area (POA) and nucleus preopticus (NPO) during the previtellogenic phase. These cells showed weak immunoreactivity during the vitellogenic and prespawning phases concomitant with darkly stained luteinising hormone (LH) immunoreactive content in the proximal pars distalis (PPD) of the pituitary gland and fully ripened follicles (stage V) in the ovary of control fish. However, in fish exposed to aquacultural stressors, TH secreting cells remained intensely stained in POA and NPO regions during the prespawning phase, indicating increased synthetic and secretory activity, which was reflected by a significantly higher DA content compared to controls. Increased DA activity as a result of stress was associated with a decrease in the LH immunoreactive content in the PPD and an absence of stage V follicles in the ovary. In the second experiment, administration of DA caused effects similar to those in stressed fish, whereas DA receptor antagonist domperidone (DOM) treatment significantly increased the LH content in the PPD and the number of stage V follicles in unstressed fish. On the other hand, treatment of stressed fish with DOM resulted in dark accumulations of LH immunoreactive content in the PPD accompanied by the presence of stage V follicles in the ovary. Taken together, these results suggest an additional pathway for the inhibitory effects of stress through dopaminergic neurones along the reproductive axis.

    The objective of this study was to integrate a bioenergetics-based modeling approach into a population stage structure to enhance life-cycle toxicity assessments of the effects of waterborne arsenic (As) on the population dynamics of the tilapia Oreochromis mossambicus. The proposed mathematical model links a Leslie matrix population model and a universal ontogenetic growth model embedding the population-level growth rate and stage-specific modes of toxic action. We present data analyses of key parameters and distributions and discuss the processes of data capture and analysis and the impact of acute/chronic As toxicity responses on population-level effects. We employed a three-parameter Hill equation model to describe the relationship between tilapia whole-body burden and mortality in order to estimate the probability of stage-specific vital rate of survival. Using the DEBtox theory, we distinguished three modes of toxic action (MOA): direct effects on growth and indirect effects via maintenance and food consumption on inhibition by arsenic of the growth of a tilapia population. The asymptotic population growth rate decreased from lambda = 1.0027 for the control group to lambda = 0.9935 for tilapia population exposed to 4 microg mL(-1) As, indicating a potential risk of population intrinsic growth rates for tilapia exposed to higher levels of waterborne As. Our results estimated that an As concentration of 1.02 microg mL(-1) would cause a 50% reduction in the tilapia population. We found that the interplay between external stressors of waterborne As concentration and internally generated modes of action decreasing feeding in the juvenile stage and increasing the maintenance cost in the adult stage had a pronounced influence on the population stage structure of tilapia.

    Males often use scent to communicate their dominance, and to mediate aggressive and breeding behaviors. In teleost fish, however, the chemical composition of male pheromones is poorly understood. Male Mozambique tilapia, Oreochromis mossambicus, use urine that signals social status and primes females to spawn. The urinary sex pheromone directed at females consists of 5β-pregnane-3α,17α,20β-triol 3-glucuronate and its 20α-epimer. The concentration of these is positively correlated with male social rank. This study tested whether dominant male urine reduces aggression in receiver males, and whether the pregnanetriol 3-glucuronates also reduce male-male aggression. Males were allowed to fight their mirror image when exposed to either: i) water control or a chemical stimulus; ii) dominant male urine (DMU); iii) C18-solid phase (C18-SPE) DMU eluate; iv) C18-SPE DMU eluate plus filtrate; v) the two pregnanetriol 3-glucuronates (P3Gs); or vi) P3Gs plus DMU filtrate. Control males mounted an increasingly aggressive fight against their image over time. However, DMU significantly reduced this aggressive response. The two urinary P3Gs did not replicate the effect of whole DMU. Neither did the C18-SPE DMU eluate, containing the P3Gs, alone, nor the C18-SPE DMU filtrate to which the two P3Gs were added. Only exposure to reconstituted DMU (C18-SPE eluate plus filtrate) restored the aggression-reducing effect of whole DMU. Olfactory activity was present in the eluate and the polar filtrate in electro-olfactogram studies. We conclude that P3Gs alone have no reducing effect on aggression and that the urinary signal driving off male competition is likely to be a multi-component pheromone, with components present in both the polar and non-polar urine fractions.

    In this study, classical and molecular cytogenetic analyses were performed in tilapia fishes, Oreochromis mossambicus (XX/XY sex determination system), O. urolepis hornorum (WZ/ZZ sex determination system) and their hybrid by crossing O. mossambicus female × O. u. hornorum male. An identical karyotype (($2n = 44$, NF (total number of chromosomal arms) = 50) was obtained from three examined tilapia samples. Genomic organization analysis of 5S rDNA revealed two different types of 5S rDNA sequences, 5S type I and 5S type II. Moreover, fluorescence in situ hybridization (FISH) with 5S rDNA probes showed six positive fluorescence signals on six chromosomes of all the analysed metaphases from the three tilapia samples. Subsequently, 45S rDNA probes were also prepared, and six positive fluorescence signals were observed on three chromosome pairs in all analysed metaphases of the three tilapia samples. The correlation between 45 rDNA localization and nucleolar organizer regions (NORs) was confirmed by silver nitrate staining in tilapia fishes. Further, different chromosomal localizations of 5S rDNA and 45S rDNA were verified by two different colour FISH probes. Briefly, the current data provide an insights for hybridization projects and breeding improvement of tilapias.

  16. 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.

    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.

    2015-11-01

    In July 1985 Peter Rona led a cruise of the National Oceanic and Atmospheric Administration (NOAA) ship Researcher as part of the NOAA Vents Program and discovered, for the first time, black smokers, massive sulfide deposits and vent biota in the Atlantic Ocean. The site of the venting phenomena was the Trans-Atlantic Geotraverse (TAG) Hydrothermal Field on the east wall of the rift valley of the Mid-Atlantic Ridge at 26°08‧N; 44°50‧W (Rona, 1985; Rona et al., 1986). In 1986, Peter and an international research team carried out multidisciplnary investigations of both active and inactive hydrothermal zones of the TAG field using the R/V Atlantis and DSV Alvin, discovering two new species of shrimp (Rimicaris exoculata and Chorocaris chacei) (Williams and Rona, 1986) and a hexagonal-shaped form (Paleodictyon nodosum) thought to be extinct (Rona et al., 2009). In 1991 a Russian crew aboard the R/V Akademik Mstislav Keldysh, with two deep-diving, human-occupied submersibles (Mir-1 and Mir-2) (Fig. 1), had the honor of having Peter Rona and a Canadian IMAX film crew from the Stephen Low Company on board to visit the TAG hydrothermal vent field. This was the first of many deep-sea interactions between Russian deep-sea scientists and their colleagues from both the U.S. and Canada. This expedition to the TAG site was part of a major Russian undersea program aimed at exploring extreme deep-sea environments; between 1988 and 2005, the Mir submersibles visited hydrothermal vents and cold seep areas in 20 deep-sea regions throughout the world's oceans (Sagalevich, 2002). Images of several of these areas (the TAG, Snake Pit, Lost City and 9°50‧N vent fields) were obtained using an IMAX camera system emplaced for the first time within the spheres of the Mir submersibles and DSV Alvin in conjunction with the filming of science documentaries (e.g., "Volcanoes of the Deep Sea") produced by the Stephen Low Company in conjunction with Emory Kristof of National Geographic and

  2. Formulating an Anarchist Sociology: Peter Kropotkin's Reading of Herbert Spencer.

    Science.gov (United States)

    Adams, Matthew S

    2016-01-01

    The work of Herbert Spencer was a crucial influence on the development of Peter Kropotkin's historical sociology. However, scholars have underestimated this relationship; either overlooking it entirely, or minimizing Kropotkin's attachment to Spencer with the aim of maintaining the utility of his political thought in the present. This article contests these interpretations by analyzing Kropotkin's reading of Spencer's epistemological, biological, and political ideas. It argues that Kropotkin was engaged in a critical dialogue with Spencer, incorporating many Spencerian principles in his own system, but also using this reading to articulate a distinctive anarchist politics.

    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

  9. (ANTI)PETER Principle - Discrete (INVERSE) Logistic Equation with Imprecisely Estimated and Stimulated Carrying Capacity

    Pankovic, V; Glavatovic, R

    2009-01-01

    In this work we consider the Peter principle and anti-Peter principle as the discrete logistic and discrete inverse logistic equation. Especially we discuss imprecisely estimated (by hierarchical control mechanism) carrying capacity, i.e. boundary (in)competence level of a hierarchy member. It implies that Peter principle holds two sub-principles. In the first one objective boundary competence level is increased for estimation error. In the second one objective boundary competence level is decreased for estimation error. Similarly, anti-Peter principle holds two sub-principles too. All this implies that paradoxical situations that follow from Peter and anti-Peter principle can be simply removed by decrease of the error of hierarchical (social) control. Also we discuss cases by Peter principle when error of the boundary competence level by estimation grows up. (Then, in fact, there is no estimation error but stimulation of the boundary level by control mechanism.) By first Peter sub-principle it implies anarch...

    The seasonal accumulation of cadmium, copper, lead, mercury and zinc was determined in sediments, water, and black-chinned tilapia (Sarotherodon melanotheron; muscle, brain, kidney and liver tissues) collected monthly from Biétri Bay. The mean water concentration of metals (in mg L(-1)) ranged from 0.01 to 0.30 (mercury), 0.02-0.26 (cadmium), 2.40-4.80 (lead), 9.05-9.68 (copper), and 12.05-19.87 (zinc). The seasonal variations showed a significant difference in the levels of mercury, cadmium and lead among season. The highest mercury (0.30 ± 0.02 μg L(-1)), cadmium (0.26 ± 0.02 mg L(-1)) and lead (4.80 ± 1.03 mg L(-1)) levels were observed during dry season, while the lowest levels (0.21 ± 0.01, 0.02 ± 0.01 and 2.40 ± 0.02 mg L(-1), respectively mercury, cadmium and lead) were measured during rainy season. The average cadmium (0.58 ± 0.36 mg L(-1)), copper (42.15 ± 19.40 mg L(-1)), lead (58.47 ± 38.10 mg kg(-1)), mercury (0.79 ± 0.47 μg kg(-1)) and zinc (187.58 ± 76.99 mg kg(-1)) concentrations determined in Biétri Bay sediments showed a similar trend as in water. The seasonal variations of mercury, cadmium and lead in tissues revealed that these metals were higher concentrated during dry and swelling seasons. The levels of zinc and copper followed by lead were higher in the tissues. The order of tissues metals concentrations was: kidney > liver > brain > muscle.

The book is a great read for anyone who wants to engage critically with positive psychology and its potentially reductive view on despair as a problem to be overcome by education....... In a refreshing contrast to the prevalent neoliberal understanding of the individual as predominantly motivated by maximising one’s own happiness, Roberts argues that we have lost sight of valuable transformative potentials, and have connected despair in education and elsewhere in a Facebook-like happiness...... for transformation and hope. In doing so, Roberts develops a thought-provoking existentialist language for a renewed discussion of the role and purpose of education against the central tendencies that are presently faced by many countries. The book is a major contribution to understanding the often overlooked...

    Specimens of three corneas in two patients with Peter's anomaly were obtained at the time of penetrating keratoplasty and studied by scanning and transmission electron microscopy. In one patient, the anomaly was monocular, and the endothelial surface showed a central defect in Descemet's layer with isolated rounded defects in the midperiphery. Fine collagenous material covered the posterior surface. The other two specimens were obtained from a patient with rubella syndrome without cataracts. The cornea showed malformation of Descemet's membrane with fibroblastic overgrowth on the endothelial layer. Epithelial-like cells and leukocytes were also found. The congenital central leukoma we believe was caused by adhesion of the pupillary membrane in our first patient, and possibly was inflammatory in our second patient.

    2014-09-01

    A 10-mo-old female red kangaroo (Macropus rufus) presented with a unilateral congenital corneal opacity OD. Complete ophthalmic examination revealed a shallow anterior chamber and a focal area of corneal edema with multiple persistent pupillary membranes extending from the iris colarette to the corneal endothelium adjacent to the edematous area of cornea. High-resolution B-scan ultrasound of the anterior segment showed an area consistent with thinning of Descemet's membrane in the area of corneal edema. Ophthalmic examination and ultrasound findings are consistent with a diagnosis of Peters anomaly, a form of anterior segment dysgenesis. An electroretinogram performed on the affected animal did not reveal any specific abnormalities. Karyotype analyses revealed a normal diploid number (2n = 20, -XX), with an abnormal pericentric inversion in the second largest chromosomal pair. The kangaroo exhibits mild compensated vision deficits in the affected eye. The maternal and paternal adult pairing has been discontinued in an effort to prevent future offspring anomalies.

    Full Text Available This article tries to highlight, from a critical perspective, the sociological aspects in the works by the famous management guru Peter Drucker. Therefore, it is proposed a discourse analysis which makes reference to the evolution of his thought, especially in two issues. Firstly, there is a focus on the changes in the relationship between corporation and society, which highlight how the author has moved from a organicist perspective of society to a denial of the social itself in his last works. Secondly, there is an analysis of the vision of the current society as a post-capitalist society, in which the State plays a minor role and knowledge reveals itself as the key socially differential factor.El presente artículo intenta hacer hincapié en los aspectos sociológicos de la obra del famoso gurú de la gestión empresarial Peter Drucker desde una perspectiva crítica. Para ello, se propone un análisis del discurso que hace referencia a la evolución de su pensamiento, concretamente en dos cuestiones. En primer lugar, se presta atención a los cambios en la relación entre empresa y sociedad, que muestran cómo el autor ha pasado de una perspectiva organicista de la sociedad a negar lo social en sus últimos trabajos. En segundo lugar, se analiza la visión que presenta de la sociedad actual como una sociedad postcapitalista, en la que el Estado tiene un papel menor y donde el conocimiento es el elemento socialmente diferenciador.

    Successful crossbreeding between Oreochromis niloticus and Sarotherodon melanotheron to produce a commercial hybrid has been difficult.The karyotypes and isoenzyme of these two species and their reciprocal hybrids (O.niloticus ♀ × S.melanotheron (♂),S.melanotheron ♀ × O.niloticus (♂),the last not included in the isoenzyme study) were investigated via metaphase chromosomes obtained from head kidney cells and electropherogram of lactate dehydrogenase (LDH) isoenzymes from the liver,kidney,white muscle,heart,and eye balls.The diploid chromosome number (2n=44) and the fundamental number (NF=50) of the four tilapia genotypes were the same.However,the karyotype of O.niloticus had three pairs of sub-metacentric (sm),twelve pairs of sub-telocentric (st),and seven pairs of telocentric (t) chromosomes,while S.melanotheron had one pair of metacentric (m),two pairs of sm,12 pairs of st,and seven pairs of t chromosomes.The reciprocal hybrids both showed a mixed karyotype range between their parents:0.5 pair of m,2.5 pairs of sm,12 pairs of st,and seven pairs of t chromosomes.In view of the electropherogram of isozymes,only the LDH of the kidney showed significant clear bands,with five bands in O.niloticus,three bands in S.melanotheron,and duplicated six bands in the hybrids.The bands varied depending on their activities and mobilities.We considered that the differences in karyotype and isoenzyme were related to the genetic mechanism for post-mating isolation,and provided some additional basic genetic background of their taxonomy.%罗非鱼类(Tilapiini)含3个属70余种,种间和属间颇易人工杂交,但尼罗罗非鱼(Oreochromis niloticus)和萨罗罗非鱼(Sarotherodon melanotheron)人工杂交难度大,产苗概率甚低,要获得数量足够的可用于生产的杂交子代相当困难.该文对这两种鱼及其正交(O.niloticus♀× Smelanotheron(♂))和反交(S.melanotheron♀×O.niloticus(♂))子代的头肾细胞的核型进行了比较.此外,采用

    It is indeed a great honor for me, and also a great pleasure, to present to you the 1988 recipient of the Robert E. Horton Medal, Peter S. Eagleson. Shortly after it became public that Pete was the winner of this year's medal, I commented to my wife that, although I had never given a citation for an AGU medalist, this was one I would really love to give. The reason is simple: there is no one in the world who better represents the standards of excellence that a hydrologist hopes to achieve and that hydrologists hope our discipline will attain than Peter Eagleson.Pete did not start his research career in hydrology. In fact, his Ph.D. thesis in 1956 and his research up to 1965 were mainly in the field of sediment sorting and transport by waves on beaches. During this period he also investigated problems related to flow-induced vibrations of plates. His research in these areas was extremely successful, producing three chapters in books and about 20 journal papers in addition to many technical reports and journal discussions. Indeed, Pete had made his mark in wave theory and sediment transport, but it was good fortune for our field that starting about 1964 his interest in hydrology overcame all his past experience and assured a reputation in the waves and sediment field, and thus he embarked on a new adventure—bringing into hydrology the scientific rigor that existed in more academically established disciplines. With his strong fluid mechanics background—he still teaches that subject to undergraduates at MIT—Pete was ideally suited to lead the field toward new problems and also toward new approaches to old problems . . . and this he did indeed! Just in 1967 he and his students published six papers, most of them in Water Resources Research, which had a strong, an almost immediate impact on the field of hydrology. Here was somebody who was tackling the modeling of overland flow with the scientific standards of fluid mechanics. At the same time, finally somebody had

    Two sibling snow leopards, a male and a female, with bilateral anterior segment dysgenesis (ASD), are reported. Both snow leopards also had colobomas of both upper eyelids. All eyes exhibited a central corneal opacity associated with a defect in posterior corneal stroma, endothelium and Descemet...... remnant of the hyaloid artery. The male had hydrocephalus and thus some of the features of Peters' plus syndrome (Peters' anomaly in addition to systemic malformations). The histological findings in the eyes of these snow leopard siblings are identical with those described in humans with Peters' anomaly....

    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.

    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.

    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.

  5. Reflections on Peter Slezak and the 'Sociology of Scientific Knowledge`

    Suchting, W. A.

    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 ...

    2015-03-01

    The aim of this paper is to provide a short history of the changes in Ferenczi's concept of early childhood, during the two decade period, 1913-1932. Initially, Ferenczi mainly emphasized children's feelings of omnipotence, which enable them to perceive themselves as strong, independent and capable human beings. By the mid-1920s, however, he felt that his earlier work did not give a good account of what comes after the stage of omnipotence, and that it did not adequately describe the difficulties in the transition from pleasure to reality principles. However, in his Clinical Diary, Ferenczi became fully aware of how fragile and insecure children are, and therefore how dangerous-yet necessary-it is for them to abandon the "stage of omnipotence" and to gain a "sense of reality". For Ferenczi, traumatized children are children who had not been loved in their early childhood, and therefore could not develop the capacity to make the journey from pleasure principle to that of reality. It will be suggested that a paradigmatic example for this kind of child is Peter Pan.

  8. 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.

The initial examination of the baby was requested for evaluation of a ‘white spot’ on the surface of her right eye. She had been hospitalized in the neonatal intensive care unit because of systemic abnormalities, such as a right clavicle fracture and microcephaly. Slit-lamp examination of the right eye showed a central corneal opacity, corneal thinning, and an iridocorneal adhesion. The lens and fundus of the right eye could not be observed. We observed no pathologic findings in the left eye. The baby's parents were informed of the high risk for spontaneous corneal perforation without external pressure. At 42 days of age, an ophthalmologic examination of the infant was again requested for evaluation of ‘tears’ from her right eye 3 hours previously. Examination revealed corneal perforation, iris protrusion, and a flat anterior chamber. We performed emergent conjunctival flap surgery. Three months following surgery, the patient's right eye was successfully preserved with no sign of inflammation or leakage. Keywords: conjunctival flap, corneal perforation, Peters' anomaly

    2012-03-01

    Full Text Available The Danish school teacher Sophus Peter Tromholt (1851–1896 was self-taught in physics, astronomy, and auroral sciences. Still, he was one of the brightest auroral researchers of the 19th century. He was the first scientist ever to organize and analyse correlated auroral observations over a wide area (entire Scandinavia moving away from incomplete localized observations. Tromholt documented the relation between auroras and sunspots and demonstrated the daily, seasonal and solar cycle-related variations in high-latitude auroral occurrence frequencies. Thus, Tromholt was the first ever to deduce from auroral observations the variations associated with what is now known as the auroral oval termed so by Khorosheva (1962 and Feldstein (1963 more than 80 yr later. He made reliable and accurate estimates of the heights of auroras several decades before this important issue was finally settled through Størmer's brilliant photographic technique. In addition to his three major scientific works (Tromholt, 1880a, 1882a, and 1885a, he wrote numerous short science notes and made huge efforts to collect historical auroral observations (Tromholt, 1898. Furthermore, Tromholt wrote a large number of popular science articles in newspapers and journals and made lecture tours all over Scandinavia and Germany, contributing to enhance the public educational level and awareness. He devoted most of his life to auroral research but as a self-taught scientist, he received little acclaim within the contemporary academic scientific society. With his non-academic background, trained at a college of education – not a university – he was never offered a position at a university or a research institution. However, Sophus Tromholt was an outstanding pioneer in auroral research.

No mortality was observed during the experiments. As a result of the study, elevated CO2 concentrations cause negative effects on the hematological parameters. At the end of the study, while the blood Carbonic Anhydrase (CA) activity, in the high CO2 group (25°C, 14mg/L CO2), statistically increased at the 7th day compared to the control group, it decreased at the 14th day (pcarbon dioxide concentration in different temperatures has negative effects on the hematological parameters and respiratory enzyme of the tilapia fish.

    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.

    An 8-week feeding trial was conducted to examine effects of wheat naturally contaminated with Fusarium mycotoxins (deoxynivalenol, DON 41 mg·kg(-1)) on growth performance and selected health indices of red tilapia (Oreochromis niloticus × O. mossambicus; initial weight = 4.3 g/fish). Five experimental diets were formulated by replacement of clean wheat with naturally contaminated wheat resulting in graded levels of DON and zearalenone (ZEN) (Diet 1 0.07/0.01, Diet 2 0.31/0.09, Diet 3 0.50/0.21, Diet 4 0.92/0.37 and Diet 5 1.15/0.98 mg·kg(-1)). Groups of 50 fish were randomly allocated into each of 20 aquaria and fed to near-satiety for eight weeks. Growth rate, feed intake and feed efficiency of fish fed the experimental diets decreased linearly with increasing levels of Fusarium mycotoxins (p 0.05). Though there was no clear evidence of overt DON toxicity to red tilapia, it is recommended that feed ingredients should be screened for Fusarium mycotoxin contamination to ensure optimal growth performance.

  10. 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.

    2016-09-01

    Peters anomaly is a form of anterior segment dysgenesis characterized by central ocular opacity and corneo-lenticular adhesions. Isolated and syndromic Peters anomaly can be observed and demonstrate significant genetic heterogeneity. We report the identification of overlapping 8q21.11 deletions in two patients with syndromic Peters anomaly via whole exome sequencing and chromosomal microarray analyses. Microdeletions of 8q21.11 were recently reported in 10 patients with highly variable phenotypes involving craniofacial features, ptosis, intellectual disability, abnormalities of the hands/feet and other defects; sclerocornea and/or microphthalmia were reported in three cases. The two additional cases presented in this report expand the phenotypic spectrum of 8q21.11 microdeletions to include Peters anomaly (seen in both patients) and persistent primary dentition (seen in one patient with a larger deletion). The two novel deletions include the ZFHX4 and PEX2 genes, which were also affected in all three previous cases involving ocular anomalies. Screening of the remaining alleles of ZFHX4 and PEX2 did not identify any additional likely pathogenic variants in either patient, suggesting a dominant mechanism (haploinsufficiency) for the identified deletion. This report provides further insight into the phenotypes associated with 8q21.11 deletions and, for the first time, reports Peters anomaly as an additional ocular feature; screening for copy number variations of the 8q21.11 region should be considered in patients with Peters anomaly and related syndromic features. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

    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.

  18. A very Freudian affair: Erich Fromm, Peter Swales and the future of psychoanalytic historiography.

    Science.gov (United States)

    Burston, Daniel

    2008-01-01

    Despite steadfast denials by Ernest Jones, Peter Gay and Paul Roazen (among others), a recent discovery by Franz Maciejewski renders it reasonably certain that Freud had an affair with his sister-in-law, Minna Bernays. While this discovery vindicates certain claims made by the controversial Freud scholar, Peter Swales, other claims of his vis-a-vis Freud's personality and ideas are open to doubt. Meanwhile, the reception of Swales's ideas, and indeed the whole controversy about Freud's love life, provide ample confirmation of many of Erich Fromm's prescient theses about Freud's personality and the politics and historiography of psychoanalysis.

    Full Text Available The narrative hero Peter Klepec is known (and laid claim to by the inhabitants of the Čabranka-Osilnica valley, the border area on the Croatian and Slovenian side of the border. There circulate a number of quite similar stories about him, in which a frail illegitimate child Peter becomes a strong man, whose supernatural powers help the needy and drive the enemies from these regions. This paper shows the changing role and diversity of interpretations of myth in time and space using the example of folk and literary hero Peter Klepec. It focuses on the historical changes in the perception of Peter Klepec: namely, on his (local function at the time of the Hapsburg imperial policy, the process of his nationalisation and dilemmas that arose following the division of the Čabranka-Osilnica area, i.e., the originating area of the creation of the legend of the two countries (Croatia and Slovenia. It shows that Klepec was due to different historical circumstances and (interpretive discourse used for different purposes. First, he served as a symbol of strength and survival in the Čabranka-Osilnica valley, and then as the Hapsburg myth that justified the existence of the monarchy facing the hostile Ottomans, and lastly as an allegory of a servile Slovene, who is always just a faithful bondsman to other masters (first under the Austro-Hungarians and then the European Union.

    2013-01-01

    R. S. Peters never explicitly talks about wisdom as being an aim of education. He does, however, in numerous places, emphasize that education is of the whole person and that, whatever else it might be about, it involves the development of knowledge and understanding. Being educated, he claims, is incompatible with being narrowly specialized.…

    De Asua, M

    2000-01-01

    The dicta from medical and philosophical authorities appearing in commentaries on the Isagoge of Johannitius may be classified according to the different roles they play in the exposition of the text. This paper establishes that the opinions of the philosophical and medico-philosophical authorities were used more frequently as the consituent elements of inferences, whereas the dicta of purely medical authorities were quoted straightforwardly as sententiae. An exception to this is Peter of Spain who does not follow any hierarchical organization of authorities; instead, he freely quotes Aristotle in opposition to the physicians as well as in support of them. These observations are explained with specific reference to Peter's ideas on the relationsip between medicine and philosophy.

    The extraordinary European journey of Tsar Peter the Great and his passage to Amsterdam, The Netherlands, allowed him to meet a great figure of medical history who offered insight into the mysteries surrounding the structure of the human body. The famous Dutch anatomist Frederik Ruysch, preeminent in dissection and anatomical preservation, impressed the emperor and inspired his love for anatomy and surgery. Peter the Great was fascinated by the study of the structure of the human body and spent many hours in the anatomical cabinet of Ruysch. This impressive collection of cadavers and anatomical specimens, described as "a perfect necropolis," was both a laboratory for teaching anatomy and a bizarre and unique form of art. The profound and enduring impression that the West made on the emperor also led him to modernize the medical services in his homeland, Russia.

    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.

    2017-01-28

    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.

    Full Text Available Introduction: Peters anomaly is a rare developmental malformation involving the anterior segment of the eye, which culminates in amblyopia or congenital blindness. Multiple ocular and/or systemic malformations have been observed with this anomaly, and novel comorbidities continue to be reported. Case Presentation: The probands were monozygotic twin boys (twin I and twin II born to consanguineous parents at 36 weeks of gestation. Coarse facial features and deep-seated eyes were noted at birth. At 6 months, ophthalmic examination revealed that both twins were unable to blink in response to light, or to fixate and follow a moving object. Both twins had prominent horizontal nystagmus. Slit-lamp examination demonstrated varying degrees of central leukoma (corneal opacity associated with iridocorneal adhesion, which is characteristic of type I Peters anomaly. No cataractous changes were observed. Normal intraocular pressure and disorganized retina were observed. Pupillary abnormalities included bilaterally underdeveloped pupils and bilateral absence of pupils was noted. Ocular MRI showed bilateral microphthalmia and optic nerve hypoplasia, with a small optic chiasm in both twins. At this age, the diagnosis of Peters anomaly was made. At 16 months of age, both twins developed deep venous thrombosis and purpuric skin lesions. Investigations revealed a hereditary thrombophilia secondary to a homozygous mutation causing protein C deficiency, which is a rare thrombotic condition. Ocular ultrasonography revealed bilateral vitreous hemorrhaging linked to altered coagulation. One twin developed bilateral inguinal hernia and cryptorchidism. Conclusion: The novel concordance of Peters anomaly in these monozygotic twins sharing a mutation in PROC gene provides further evidence that this anomaly has a genetic basis. Hypoplasia of the optic nerves and optic chiasm, along with severe protein C deficiency and bilateral absence of the pupils, are associated

    In 2013 the Nobel Prize in Physics was awarded to Francois Englert and Peter Higgs for their development in 1964 of the mass generation mechanism (the Higgs mechanism) in local gauge theories. This mechanism requires the existence of a massive scalar particle, the Higgs boson, and in 2012 the Higgs boson was finally observed at the Large Hadron Collider after an almost half a century search. In this talk we review the work of these Nobel recipients and discuss its implications.

    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.

    Peters Plus syndrome (PPS), a congenital disorder of glycosylation, results from recessive mutations affecting the glucosyltransferase B3GLCT, leading to congenital corneal opacity and diverse extra-ocular manifestations. Together with the fucosyltransferase POFUT2, B3GLCT adds Glucoseβ1-3Fucose disaccharide to a consensus sequence in thrombospondin type 1 repeats (TSRs) of several proteins. Which of these target proteins is functionally compromised in PPS is unknown. We report here that haploinsufficiency of murine Adamts9, encoding a secreted metalloproteinase with 15 TSRs, leads to congenital corneal opacity and Peters anomaly (persistent lens-cornea adhesion), which is a hallmark of PPS. Mass spectrometry of recombinant ADAMTS9 showed that 9 of 12 TSRs with the O-fucosylation consensus sequence carried the Glucoseβ1-3Fucose disaccharide and B3GLCT knockdown reduced ADAMTS9 secretion in HEK293F cells. Together, the genetic and biochemical findings imply a dosage-dependent role for ADAMTS9 in ocular morphogenesis. Reduced secretion of ADAMTS9 in the absence of B3GLCT is proposed as a mechanism of Peters anomaly in PPS. The functional link between ADAMTS9 and B3GLCT established here also provides credence to their recently reported association with age-related macular degeneration. PMID:27687499

  11. For a theory of children’s literature: Peter Hunt’s case

    Directory of Open Access Journals (Sweden)

    LEONARDO FRANCISCO SOARES

    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.

    Directory of Open Access Journals (Sweden)

    2016-05-01

    Full Text Available According to scholars of masculinity studies, manhood is won or lost through the performance of gender-based expectations. In any given culture, masculinities exist in hierarchal relationships. The author of the book of Acts shows Peter demonstrating elite masculine performances in the narrative of Acts. Through Peter’s self-control, and the lack of self-control on the part of those who oppose him, his persuasive, public speech and his ability to control others in the text, Peter exhibits a masculinity that contradicts early portraits of Peter found in 1 Corinthians and the gospels of Matthew, Mark and John. Peter is not overcome by other people in Acts, and he demonstrates a masculinity that is complicit with the types of masculinities prized by the Romans and often considered out of the reach of foreigners.

    2012-05-01

    The Peter Principle is a theory that provides a paradoxical explanation for job incompetence in a hierarchical organisation. It argues that should staff be competent at a given level, their competence may not be implicit at higher levels due to the differences in the skill set required. Furthering the work of a recent investigation into the Peter Principle utilising agent based simulation, this paper explores external factors upon varying promotion strategies to assess efficiency. Through additional elements of social networks and organisational thought, a more representative view of workplace interaction is presented. Results of the simulation found that although the Peter Principle affects efficiency, it may not be to the levels previously suggested. Furthermore promotion on merit provided the most favourable maximum and minimum efficiency margins, given the absence of clear evidence pertaining to the existence of the Peter Principle.

    Directory of Open Access Journals (Sweden)

    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

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.

  8. [Health and dietetics in medieval preventive medicine: the health regimen of Peter of Spain (thirteenth century)].

    Santos, Dulce O Amarante Dos; Fagundes, Maria Daílza da Conceição

    2010-06-01

    This text is an analysis of a preventive medical work, Liber de conservanda sanitate, composed in the thirteenth century by the Portuguese physician and doctor, Peter of Spain (?1210-1277). His work enables us to look at the conceptions of health and hygiene and understand the social role of university physicians in medieval preventive medicine. The work constantly displays the notion of the balance in corporal health between internal elements, or natural things (complexion, for example), and external ones, or non-natural things (air, sleep, exercise, food, baths, passions of the soul).

  9. Perceptions of Jewish Female Bodies through Gustav Klimt and Peter Altenberg

    Full Text Available Gustav Klimt and Peter Altenberg are two figures within Viennese fin-de-siècle cultural production whose art may reveal a perception of local Jewish culture through their different foci on the non-European female body image. Both men have moments in their career, when their attention turns to non-European cultures, through which they inadvertently represent and interpret their own. A selection of these two artists’ most well-known works demonstrate two frameworks in which Viennese Jewishness can be read through an alignment of the female body with Asian and African cultures.

    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.

  13. Lunatic Asylum in the Workhouse: St Peter's Hospital, Bristol, 1698-1861.

    Smith, Leonard

    2017-04-01

    In recent years there has been growing acknowledgement of the place of workhouses within the range of institutional provision for mentally disordered people in nineteenth-century England. This article explores the situation in Bristol, where an entrenched workhouse-based model was retained for an extended period in the face of mounting external ideological and political pressures to provide a proper lunatic asylum. It signified a contest between the modernising, reformist inclinations of central state agencies and local bodies seeking to retain their freedom of action. The conflict exposed contrasting conceptions regarding the nature of services to which the insane poor were entitled. Bristol pioneered establishment of a central workhouse under the old Poor Law; 'St Peter's Hospital' was opened in 1698. As a multi-purpose welfare institution its clientele included 'lunatics' and 'idiots', for whom there was specific accommodation from before the 1760s. Despite an unhealthy city centre location and crowded, dilapidated buildings, the enterprising Bristol authorities secured St Peter's Hospital's designation as a county lunatic asylum in 1823. Its many deficiencies brought condemnation in the national survey of provision for the insane in 1844. In the period following the key lunacy legislation of 1845, the Home Office and Commissioners in Lunacy demanded the replacement of the putative lunatic asylum within Bristol's workhouse by a new borough asylum outside the city. The Bristol authorities resisted stoutly for several years, but were eventually forced to succumb and adopt the prescribed model of institutional care for the pauper insane.

  14. Bicycles, Airplanes and Peter Pans: Flying Scenes in Steven Spielberg's Films

    Directory of Open Access Journals (Sweden)

    Emilio Audissino

    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.

    Full Text Available Purpose: To report our findings in an infant with Peters anomaly type II whose retinopathy of prematurity (ROP was treated with an anti-VEGF agent and surgeries. Case Report: A male infant weighing 548 g was born prematurely at 23 weeks and 1 day with corneal opacity and shallow anterior chambers in both eyes. At the postmenstrual age of 35 weeks and 3 days, the infant was tentatively diagnosed with stage 3 ROP because of a dilated tunica vasculosa lentis and ultrasonographic findings. The boy was treated with bilateral intravitreal injections of bevacizumab (IVB because laser photocoagulation of the retina could not be performed due to the corneal opacity. The retina in the right eye detached 3 times, namely 5 days, 16 days, and 7 months after the IVB; encircling the scleral buckle and a vitrectomy with endolaser photocoagulation were therefore required. In his left eye, the retina was reattached after the initial IVB, and no additional treatment was required. ROP was not reactivated in both eyes until the last examination at the age of 2 years and 6 months. Conclusions: Our results showed that IVB is a useful treatment for ROP in patients with Peters anomaly. However, a retinal detachment can be a complication after IVB. The optimal timing of IVB for ROP in infants with hazy media needs to be determined.

    The qualitative and quantitative compositions of free-living marine nematodes were studied in Rifovaya Bay (Peter the Great Gulf, Sea of Japan). It was found that the density distribution of nematode populations in bottom sediments of Rifovaya Bay is nonuniform. In total, 72 nematode species were found, including Oncholaimium paraolium, Viscosia epapilosa, and Monoposthia latiannulata on all types of substrates. The dominant trophic group comprised "predators" (2B) and "scrapers" (2A). It was shown that the species composition of nematodes in Rifovaya Bay is very similar to the species composition of nematodes in the other areas of Peter the Great Gulf.

  2. Cities of God in northern Asia minor: Using Stark's social theories to reconstruct Peter's communities

    Mark W. Wilson

    2011-03-01

    Full Text Available This article used seven hypotheses from R. Stark�s Cities of God (2007 as a heuristic tool toinvestigate the rise of Christianity in the five Roman provinces mentioned in 1 Peter 1:1. It affirmed that the Christian communities in these provinces were located in an urban, not rural, setting. Building on the research of Hort and Hemer, seven major cities in these provinces were proposed to test Stark�s hypotheses with. These cities are Sinope and Amisus in Pontus, Ancyra in Galatia, Caesarea Mazaca in Cappadocia, Dorylaeum in Asia and Nicea and Nicomedia in Bithynia. An important factor noted in several of these cities was their prominence as a commercial seaport and the presence of a Diaspora Jewish community. Utilising this methodological approach helped to elucidate more fully the audience of 1 Peter�s geographic and historical background.

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

    Science.gov (United States)

    Bradshaw, A

    1996-02-01

    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.

    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.

    The acute toxicity of heavy metals in combination to the common guppy has been reported. Information on the combined effects of chromium and nickel to fish is rather scarce. Toxicity of nickel and chromium to fish is generally low. These two elements are usually less toxic than silver, cadmium, copper and thallium; depending on test conditions, these may also be less hazardous than zinc, lead and arsenic. The present study was undertaken to investigate the acute toxicity of Ni and Cr singly and the toxic interaction of these two metal ions on survival of the common guppy, Poecilia reticulata (Peters). This species was selected for static bioassays because it can be easily cultured and raised under laboratory conditions through a complete life cycle, and it is one of the most common fish used for laboratory toxicity studies.

    Full Text Available The article suggests that the relationship between Christ’s death and the defeat of the devil (Heb 2:14, as well as the metaphor of the devil as an adversary prowling like a roaring lion (1 Pt 5:8 possibly share the same background – i.e., the ancient Roman judicial phenomenon of  crimen calumniae. This legal practice was established to stop prosecutors from bringing forward false charges. Convicted calumniators were removed from office and suffered additional punishments. This background might help explain the fact that the devil was defeated according to Hebrews by way of false accusation, and that the devil in 1 Peter does not attack the believers, but is only on the prowl for justified accusations.

    Full Text Available The fallout of the 2008 global financial crisis and frequent disregard for labor, environmental, and social standards have instilled new vigor into the study of ethics and virtues. In the contemporary knowledge society, the issue of which virtues the modern day workforce needs to possess is of crucial significance. This study specifies the virtues laid out in the management theory of Peter Drucker (1909-2005, focusing upon the conceptual category of the knowledge worker as the primary unit of the contemporary information and innovation-based knowledge society. The idea and role of intellectual virtues are not yet fully developed in the literature, especially as those identified in this article are the source of critical and creative thinking. This intervention, therefore, identifies prudence, effectiveness, excellence, integrity, and truthfulness as the knowledge worker’s intellectual virtues, whereas practical wisdom, responsibility, cooperation, and courage are seen to constitute the knowledge worker’s moral character.

  12. Peter Singer and 'lives not worth living'--comments on a flawed argument from analogy.

    Science.gov (United States)

    Sundström, P

    1995-02-01

    The Australian bioethicist Peter Singer has presented an intriguing argument for the opinion that it is quite proper (morally) to deem the lives of certain individuals not worth living and so to kill them. The argument is based on the alleged analogy between the ordinary clinical judgement that a life with a broken leg is worse than a life with an intact leg (other things being equal), and that the broken leg therefore ought to be mended, on the one hand, and the judgement that the lives of some individuals, for example, severely disabled infants, are not worth living and therefore ought to be terminated, on the other. In the present article it is argued that Singer's argument is flawed, intellectually and/or ethically.

  13. Common ground on surgical abortion?--engaging Peter Singer on the moral status of potential persons.

    Science.gov (United States)

    Camosy, Charles C

    2008-12-01

    The debate over surgical abortion is certainly one of the most divisive in ethical discourse and for many it seems interminable. However, this paper argues that a primary reason for this is confusion with regard to what issues are actually under dispute. When looking at an entrenched and articulate figure on one side of the debate, Peter Singer, and comparing his views with those of his opponents, one finds that the disputed issue is actually quite a narrow one: the moral status of potential persons. Finding this common ground clears the conceptual space for a fruitful argument: the thesis of which is that most, including Singer, who argue that potential persons do not have full personal moral status fail to make the necessary distinction between natural potential (which confers moral status) and practical potential (which admittedly does not).

    2006-10-01

    Full Text Available This article explores the collective works of Peter McLaren and his contribution to critical pedagogy within the field of education and beyond the academy. To understand how McLaren’s work took a radical turn in the 1990s, the article traces the historical development of his praxis. In particular, McLaren’s engagement with the postmodern Left and his response to developments in British educational Marxism are highlighted in this paper. Bringing Marxism, class analysis and politics back into the heart of education, McLaren has situated himself at the forefront of remaking critical pedagogy as a material force for social change. The resulting fusion has provoked a storm of controversy amongst the educational Left. Beyond this, however, has been the influence of critical pedagogy in social spheres beyond the university and academia, including the mass workers movement.

  16. Alan Strange as an adolescent: a discussion of Peter Shaffer's Equus.

    Science.gov (United States)

    Glenn, J

    1976-01-01

    Psychoanalytic knowledge of adolescence helps us to understand the protagonists of Peter Shaffer's play Equus. Alan Strang, the seventeen-year-old who maimed six horses, had undergone a retreat from oedipal wishes to narcissism typical of teenagers. His fragile attempts at achieving a sound sense of identity are undermined when his seeking of a noninestuous object produces panic and impotence. Dr. Dysart, the psychiatrist who envies his patient's passion, and fears hurting him through treatment, displays in an exaggerated way countertransferences often seen in therapists of adolescents. In addition, his doubts have some foundation in that the treatment he employs, catharsis, can encourage primitive defenses and the outpouring of uncontrolled, unneutralized drive derivatives. This is more likely to prevent adaptive creativity than the cure the doctor dreads. Finally, some technical problems in dealing with sublimations in psychoanalysis (which is not Dr. Dysart's form of treatment) are discussed.

    1991-09-01

    Peter Anthony Motteux (1663-1718), a Huguenot refugee in London, established a literary reputation by completing Sir Thomas Urquhart's translation of Rabelais' Gargantua and Pantagruel, then Cervantes' Don Quixote. He later became an import-export merchant. On his 55th birthday he donned his scarlet cloak and went out on the town. He picked up a prostitute and after some dalliance returned to her bordello. Shortly thereafter he was found dead, although the evidence is that he was in good health when he arrived. Literary evidence is that he died from assisted erotic asphyxia, a variant of autoerotic asphyxia, cf. the case of Frantisek Koczwara (Am J Forensic Med Pathol 5:145-149, 1984.)

The first pattern that connects the letters is a Geisttradition (K Aland, guaranteeing continuity of tradition. The second is the interrelationship between faith and ethics (fides quae and fides qua. The combination of sanctification and eschatology is a third pattern connecting the three documents. Finally, two florilegia can be identified (one from the Old Testament and apocrypha, and one from the chokmatic tradition, suggesting a fourth pattern: a warning against ungodliness and infidelity. The existence of a Petrine group could represent a preliminary stage of subsequent Early Catholicism.

    Full Text Available A quantitative research of parasites of 67 endemic frog Telmatobius jelskii (Peters, 1863 collected from Laguna Tucto (76°46'11"W, 10°39'11"S where Pativilca River is originated was conducted, and was located in the Province of Oyon, high Andean area from the Department of Lima, Peru during September-October 2000. Of the frogs collected, 23 were females and 44 males. Male showed a length between 5.2 ± 0.5 cm (range = 4.0-6.4 cm and female between 5.5 ± 1 cm (range = 3.9-7.6 cm and were not found differences between both sexes. 86 specimens of parasite and three species in total during all the survey were collected. 28 hosts were infected (41.8%. twenty-five hosts (37.3% showed infection with one parasite species, and three (4.5% had two parasite species. Three parasite species were found: Gorgoderina parvicava Travassos, 1922 (Digenea: Gorgoderidae (Prevalence = 40.3%; mean Intensity = 3.1; mean abundance = 1.2, Cylindrotaenia americana Jewell, 1916 (Cestoda: Proteocephalidae (Prevalence = 3%; mean Intensity = 1; mean abundance = 0.02 and Aplectana hylambatis (Baylis, 1927 (Nematoda: Cosmocercidae (Prevalence = 3%; mean Intensity = 1; mean abundance = 0.02. G. parvicava had an overdispersed distribution and was the dominant species. An effect of sex and length with prevalence and mean abundance of infection of G. parvicava was not found. The relationship of helminthes parasites with T. jelskii is discussed. G. parvicava and C. americana are new records for T. jelskii.

  20. The search for asbestos within the Peter Mitchell Taconite iron ore mine, near Babbitt, Minnesota.

    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.

    2008-10-01

    We explored molecular and morphological alteration in gill mitochondria-rich (MR) cells of Mozambique tilapia, Oreochromis mossambicus, acclimated to deionized freshwater (DFW), freshwater (FW), 1/3-diluted seawater (1/3 SW) and seawater (SW). Scanning electron microscopic observations revealed that the apical membrane of MR cells appeared as a flat or slightly projecting disk in DFW and FW, being larger in DFW than in FW. In contrast, the apical membrane typically formed a pit structure in 1/3 SW and SW. The mRNA expression levels of Na(+)/H(+) exchanger-3 (NHE3) and Na(+)/Cl(-) cotransporter (NCC) in the gills were increased with decreasing environmental salinity, whereas Na(+)/K(+)/2Cl(-) cotransporter-1a (NKCC1a) expression was upregulated by increasing salinity. Immunofluorescence staining showed that the MR cell population of DFW- and FW-acclimated tilapia consisted mostly of MR cells with apical NHE3 and those with apical-NCC; MR cells with basolateral NKCC1a dominated in SW-acclimated tilapia. These results indicated that apical-NHE3 and apical-NCC MR cells were ion-absorbing cells, and that basolateral-NKCC1a MR cells were ion-secreting cells. In fish acclimated to 1/3 SW, both ion-absorbing and secreting cells existed in the gills, suggesting that fish in near-isotonic water were equipped with mechanisms of both hyper- and hypoosmoregulation to prepare for environmental salinity changes.

  20. HL-10 on lakebed with Jerauld R. Gentry, Peter Hoag, John A. Manke, and Bill Dana

    The four principal HL-10 pilots are seen here with the lifting body aircraft. They are, left to right; Air Force Major Jerauld R. Gentry, Air Force test pilot Peter Hoag, and NASA pilots John A. Manke and Bill Dana. All are wearing the pressure suits needed for flying above 50,000 feet. 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-F2/F3

    We present a few newly found old sunspot observations from the years AD 1708, 1709, and 1710, which were obtained by Peter Becker from Rostock, Germany. For 1709, Becker gave a detailed drawing: he observed a sunspot group made up of two spots on Jan 5, 6, and 7, and just one of the two spots was observed on Jan 8 and 9. We present his drawing and his explanatory text. We can measure the latitude and longitude of these two spots and estimate their sizes for all five days. While the spots and groups in 1708 and the spot on four of the five days in January 1709 were known before from other observers (e.g. Hoyt & Schatten 1998), the location of the spots in early January 1709 were not known before, so that they can now be considered in reconstructed butterfly diagrams. The sunspots detected by Becker on 1709 Jan 5 and 1710 Sep 10 were not known before at all, as the only observer known for those two dates, La Hire, did not detect that spot (group). We estimate new group sunspot numbers for the relevant days,...

  3. Secularização e mercado religioso em Peter Berger.

    Directory of Open Access Journals (Sweden)

    Arilson Oliveira

    2015-06-01

    Full Text Available Peter Berger apresenta um diagnóstico da situação das religiões na sociedade ocidental moderna, defendendo a tese de que os processos infraestruturais concretos desta sociedade trouxeram como reflexo a “secularização”. Esta, por sua vez, não impediu, como muitos argumentam, o impulso religioso que motivou os homens a aderirem à religião de forma intensa, dando base para o que ele caracteriza como “dessecularização”; sendo o mundo de hoje, portanto, e com algumas exceções, tão impetuosamente religioso quanto antes. O que implica dizer que embora não seja possível determinar com precisão como será o futuro dos diversos movimentos religiosos, Berger sustenta que não há razão para pensar que o mundo do século XXI será menos religioso do que o mundo anterior. Essa nova dinâmica levou as religiões a operarem com a lógica de mercado, o que implicou na necessidade de adaptação de seus ritos e crenças, de forma a atender a demanda das consciências individuais.

  4. 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.

    2017-04-01

    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.

  5. "Pop" psychoanalysis, kitsch, and the "as if" theater: further notes on Peter Shaffer's Equus.

    Science.gov (United States)

    Gifford, S

    1976-01-01

    This paper is intended as an examination of Dr. Stamm's (1975) paper and of Dr. Jules Glenn's discussion of Peter Shaffer's previous work. Its premise is the futility of subjecting Equus to a traditional psychoanalytic investigation, as a product of the playwright's unconscious, when the play represents a skillful, highly conscious use of analytic cliches to manipulate the audience. This phenomenon, however, and the play's great popularity prompt some reflections on the nature of kitsch, or false art, and its differences from authentic drama. The experience of kitsch can be identified when the spectator feels coerced by exaggerated, unconvincing theatrical devices, and fails to experience genuine empathy with the characters in a play. In the experience of authentic tragedy there is some element of voluntary surrender, of suspension of disbelief with full consent of will, as in the Aristotelian concept of catharsis. Shaffer's play is discussed as an illustration of this distinction and its relation to pseudoemotionality, the impostor syndrome, and the "as if" personality. In conclusion, the play's failure to evoke a genuine emotional response is explained by interpreting Equus as an "as if" tragedy.

  6. Cloning and characterization of peter pan, a novel Drosophila gene required for larval growth.

    Migeon, J C; Garfinkel, M S; Edgar, B A

    1999-06-01

    We identified a new Drosophila gene, peter pan (ppan), in a screen for larval growth-defective mutants. ppan mutant larvae do not grow and show minimal DNA replication but can survive until well after their heterozygotic siblings have pupariated. We cloned the ppan gene by P-element plasmid rescue. ppan belongs to a highly conserved gene family that includes Saccharomyces cerevisiae SSF1 and SSF2, as well as Schizosaccharomyces pombe, Arabidopsis, Caenorhabditis elegans, mouse, and human homologues. Deletion of both SSF1 and SSF2 in yeast is lethal, and depletion of the gene products causes cell division arrest. Mosaic analysis of ppan mutant clones in Drosophila imaginal disks and ovaries demonstrates that ppan is cell autonomous and required for normal mitotic growth but is not absolutely required for general biosynthesis or DNA replication. Overexpression of the wild-type gene causes cell death and disrupts the normal development of adult structures. The ppan gene family appears to have an essential and evolutionarily conserved role in cell growth.

  7. Pescadillo homologue 1 and Peter Pan function during Xenopus laevis pronephros development.

    2011-10-01

    pes1 (pescadillo homologue 1) and ppan (Peter Pan) are multifunctional proteins involved in ribosome biogenesis, cell proliferation, apoptosis, cell migration and regulation of gene expression. Both proteins are required for early neural development in Xenopus laevis, as previously demonstrated. We show that the expression of both genes in the developing pronephros depends on wnt4 and fzd3 (frizzled homologue 3) function. Loss of pes1 or ppan by MO (morpholino oligonucleotide)-based knockdown approaches resulted in strong malformations during pronephric tubule formation. Defects were already notable during specification of pronephric progenitor cells, as shown by lhx1 expression. Moreover, we demonstrated that Xenopus pes1 and ppan interact physically and functionally and that pes1 and ppan can cross-rescue the loss of function phenotype of one another. Interference with rRNA synthesis, however, did not result in a similar early pronephros phenotype. These results demonstrate that pes1 and ppan are required for Xenopus pronephros development and indicate that their function in the pronephros is independent of their role in ribosome biosynthesis.

  8. Lorentz Spin-Foam with Non Unitary Representations by use of Holomorphic Peter-Weyl Theorem

    Perlov, Leonid

    2013-01-01

    We use the non-unitary spinor representations of SL(2,C) and the recently proved Holomorphic Peter-Weyl theorem to define the Hilbert space based on the holomorphic spin-networks, the non-unitary spin-foam, solve the simplicity constraints and calculate the vertex amplitude. The diagonal simplicity constraint provides two solutions. The first solution: Immirzi $\\gamma = i$ with the irreducible representations $(j_1, j_2)$ projected to $(0, j)$ and the second solution: Immirzi $\\gamma = -i$ and the irreducible non-unitary representations projected to $(j, 0)$. The off-diagonal constraint selects only the first of these two solutions. The solution is interesting in two aspects: a) it turns to be a topological BF model. b) Immirzi parameter $\\gamma = i$ corresponds to Ashtekar's self-dual connection of the complexified algebra $sl(2,C)\\otimes C$. The transition amplitude is finite and very similar to BF Euclidean model. We discuss the inner product Lorentz invariance and the viability of the non-unitary represen...

    At Peter I the regular army was organized and the system of target state deliveries to troops of the food is created. Provisioning and fodder was normalized as portion and ration. Portion was contained the products forpeoplefood, and ration - fodder for horses food who were used by the serviceman. Portion and ration unit was identical to all categories of the military personnel. Difference in food level consisted in that, how many portions and rations serviceman received. Up to the end of existence of Russian army in 1918 in each rota there were contractor and the cook who were engaged in foodstuff and cooking under sergeant-major and one of rota officers supervision. According to the Charter it was necessary to carry with respect and attention to officers and soldiers, their needs, including in the field of supply and catering services and providing with the food: Despite the lack of scientific justification, soldiers' nutrition was sufficient to provide fighting capacity of the Russian army.

  10. Jared Diamond and Peter Turchin: Two contemporary theories of social collapse

    Directory of Open Access Journals (Sweden)

    Gajić Aleksandar Saša

    2014-01-01

    Full Text Available Theories of social collapse are not only the views that characterize “societies deep in crisis”, but rather an expression of lack of belief in prosperity and central importance of the civilization in which we live. These theories follow processes of degradation of human societies, the decline of civilization`s powers and the loss of its cultural values resulting in their complete disappearance. This paper defines the subject of study and provides an overview of the history of these theories and their contemporary types by taking the main causes of collapse criteria as the basis for theory building. After the review of contemporary multi-factor analysis of collapse, mainly within the science of complex systems, full attention is focused on two atypical, yet very productive, contemporary theories of social collapse that are elaborated in detail: Jared Diamond`s theory, which studies social collapses by observing relations of other variables that can lead to collapse with environmental problems as central; and Peter Turchin`s theory which, revitalizing with modern scientific achievements Ibn Khaldun`s classical theory of “asabia” (group feeling, spirit of community, sees social collapses as a consequence of the decline of cohesion provided by asabia. The final part of the work gives a critical review of these two theories and their relation with classical theories of social collapse (primarily those of Arnold Toynbee and points to their mutual productive complementarity.

    Full Text Available The two official visits to Paris made by Russian sovereigns, the first one by Peter I in Spring 1717 and the second one by Alexander I in Spring 1814, have been significant events for the history of Russian-French relations and for European history in general. Each of these trips generated an extensive literature and the circumstances, the origins, the goals, and outcomes of the sovereigns’ stay in the French capital are very well documented. The authors proposed to analyze these trips in a comparative and diachronic way, considering that despite their differences in terms of cultural and political contexts, this approach is relevant. Indeed, the article aims at showing that the visits had a common impact: they contributed to reform stereotypes about Russia and Russians in the eyes of French elites and public opinion, and beyond, in European public opinion. During their trips, convincingly demonstrating that Russia belongs to the European space, the two monarchs significantly transformed the perception of their country, so far perceived as a barbaric, tyrannical and potentially dangerous country for Europe. However, at the same time, the authors conclude that the deconstruction of old stereotypes did not lead to their complete eradication. As a result, in European public opinion, emerged a «dual perception» of Russia that is a negative one, going back to late medieval tradition, and a more positive one, associated with the recognition of its belonging to the modern European cultural space.

    We present a few newly found old sunspot observations from the years AD 1708, 1709, and 1710, which were obtained by Peter Becker from Rostock, Germany. For 1709, Becker gave a detailed drawing: he observed a sunspot group made up of two spots on January 5, 6, and 7, and just one of the two spots was observed on January 8 and 9. We present his drawing and his explanatory text. We can measure the latitude and longitude of these two spots and estimate their sizes for all five days. While the spots and groups in 1708 and the spot on four of the five days in January 1709 were known before from other observers (e.g. Hoyt & Schatten 1998), the location of the spots in early January 1709 were not known before, so that they can now be considered in reconstructed butterfly diagrams. The sunspots detected by Becker on 1709 January 5 and 1710 September 10 were not known before at all, as the only observer known for those two dates, La Hire, did not detect that spot (group). We estimate new group sunspot numbers for the relevant days, months, and years. The time around 1708-1710 is important, because it documents the recovery of solar activity towards the end of the Maunder Grand Minimum. We also show two new spot observations from G. Kirch for 1708 September 13 and 14 as described in his letter to Wurzelbaur (dated Berlin AD 1708 December 19).

    Types of Rhyparochromidae (Hemiptera: Heteroptera: Lygaeoidea) species described by Carl Peter Thunberg, deposited in the Museum of Evolution (formerly Zoologiska Institut), Uppsala University, Uppsala, Sweden, were reexamined and the taxonomic and nomenclatural problems that existed among those species discussed and resolved as required. Lectotypes are designated for Cimex caffer Thunberg, 1784, Lygaeus ater Thunberg, 1822, Lygaeus biguttatus Thunberg, 1822, and Pendulinus guttatus Thunberg, 1825. The lectotype of Pendulinus (now Metochus) guttatus is designated as neotype of Pendulinus (now Metochus) uniguttatus Thunberg, 1822; as a result the former name becomes junior objective synonym of the latter. The following taxonomic changes are proposed: Lethaeus ater (Thunberg, 1822), new combination (from Lygaeus); Migdilybs biguttatus (Thunberg, 1822), new combination (from Lygaeus) = Migdilybs furcifer Hesse, 1925, new subjective synonym; Metochus uniguttatus (Thunberg, 1822) = Metochus bengalensis (Dallas, 1852), confirmed subjective synonym = Metochus yeh (Dohrn, 1860), confirmed subjective synonym; Raglius alboacuminatus (Goeze, 1778) = Cimex caffer Thunberg, 1874, confirmed subjective synonym. Lethaeus barberi Slater, 1964 does not belong to Lethaeus Dallas, 1852 but currently it cannot be placed with confidence in any existing genus.

    Fenpyroximate (FP), an acaricide, is widely used in the prevention of acarids (mites) in fruit plant gardens. In this study, the acute toxic effects of different concentrations of FP were investigated using adult guppy (Poecilia reticulata Peters, 1859). Guppy adults were exposed to a range of FP concentrations (25, 50, 75, 100, 125, and 150 µg/L) during 48 h. Static method, which is one of the acute toxicity experiments, has been used in this study. According to probit analysis, the 48-h median lethal concentration (LC50) value of FP at 26°C was found to be 72.821 µg/L. Sublethal exposures were predetermined based on 48-h LC50 value. Guppies were exposed to low concentrations (15, 25, and 50 µg/L) of FP for 48 h. Signs of paralysis and behavior deformations were monitored every 12 h in a number of live and dead adults. Low concentrations of FP were also responsible for erratic swimming, loss of equilibrium, and being lethargic. Liver histology revealed several pathological damages including congestion, picnotic nucleus, sinusoidal dilatation, increase in melanomacrophagic centers, and endothelial degeneration. Finally, the toxicity test results provided 48-h LC50 value for FP, and low concentrations of FP can be highly detrimental to guppy adults with clear evidence of behavioral and histologic effects.

Nusantara Bioscience 4: 6-10. This research was performed to determine and compare acute toxicity of diazinon and deltamethrin as potential dangerous organic pesticides to assess mortality effects of these chemicals to the freshwater guppy Poecilia reticulata. LC50 of 24 h, 48 h, 72 h, and 96 h was attained by probit analysis by Finney’s and using the maximum-likelihood procedure (SPSS. The 24-96 h LC50 for the diazinon were 40.9±0.98, 33.2±0.84, 23.2±0.74 and 16.8±0.57 ppm respectively. The 24-96 h LC50 for the deltamethrin were 0.297±0.13, 0.236±0.16, 0.204±0.47 and 0.195±0.06 ppm respectively. In the present study, LC50 values indicated that deltamethrin was more toxic than diazinon to this species. LC50 values obtained in the present study were different from the corresponding values that have been published in the literature for other species of fish.

    Tetrahymena is a protozoan parasite, which infects guppy, Poecilia reticulata Peters, and causes substantial economical losses in commercial farms worldwide. Studies of guppy infected by Tetrahymena require standardized infection protocols. The LD50 for Tetrahymena infection of guppies by intraperitoneal (IP) injection was calibrated, and the level obtained was 946 parasites per fish. Guppy infection with Tetrahymena by immersion, imitating the natural route of infection via the integument, was studied under normal or stress conditions. Exposure to cold and netting (CNI) and to cold only (CI) followed by immersion exposure to 10 000 Tetrahymena per mL resulted in 22.5% and 19.2% mortality, respectively, as compared to 14.2% and 10% in groups that were netted only (NI) or non-stressed (I). Histopathology revealed that immersion infection resulted in a systemic infection. Lysozyme levels, measured 3 weeks after infection, were significantly higher in the CNI group (288 μg per mg protein) compared with CI-, NI- and I-treated groups (94.5, 64 and 62.3 μg mg(-1), respectively). There was no evident parasite immobilization activity in body homogenates, suggesting no development of acquired immunity. Re-infection by IP injection revealed no increase in protection in any of the treatment groups, mortality range of 56.3-75%, higher than in the non-exposed control (40.6% mortality).

    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.

    Full Text Available http://dx.doi.org/10.5007/1677-2954.2009v8n1p9Peter 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

  19. Constructing Protestant and Catholic Peters: A comparative study in the literary use of the New Testament and ecclesiastical tradition

    2009-07-01

    Full Text Available Just as literary authors have long taken liberties with the biblical accounts of Jesus Christ and shaped Him to fit their own agendas, they have also appropriated considerable artistic licence in enhancing the meagre information about Peter in the New Testament when constructing fictional narratives about him. A comparison of The Big Fisherman by the theologically liberal American Congregationalist Lloyd C Douglas and Simon Peter the Fisherman by the Austrian Catholic Kurt Frieberger illustrates how two accomplished novelists, drawing in part on similar sources, created markedly different and to some extent predictable images of this apostle. Neither novel is fully faithful to the New Testament evidence; both evince the influence of extrabiblical sources.

    In the 19th century, several astronomers made observations of sunspots, recording their positions and sometimes their areas. These observations were published in the form of extensive tables, but have been unhelpful until now. Three of these observers were Richard C. Carrington, Christian H. F. Peters, and Warren de la Rue (and their respective collaborators). They published, in various articles the data corresponding to 26 641 sunspot positions (Carrington, Peters, and de la Rue registered 4 900, 14 040, and 7 701 sunspot positions, respectively). In this paper we present a translation of more than 400 pages of their printed numerical tables into a machine readable format, including an initial analysis targeted at detecting possible mistakes in the reading or in the original transcription. The observations carried out by these three astronomers have been made available at the Centre de Don\\'ees Astronomiques de Strasbourg (http://cdsarc.u-strasbg.fr/cgi-bin/VizieR?-source=VI/138).

    A habitat based assessment was conducted of the US Army Corps of Engineers' Green Peter-Foster Dam and Reservoir Project on the Middle Fork Santiam River, Oregon, to determine losses or gains resulting from the development and operation of the hydroelectric related components of the project. Preconstruction, postconstruction, and recent vegetation cover types at the project site were mapped based on aerial photographs from 1955, 1972, and 1979, respectively. Vegetation cover types were identified within the affected area and acreages of each type at each period were determined. Eleven wildlife target species were selected to represent a cross-section of species groups affected by the project. An interagency team evaluated the suitability of the habitat to support the target species at each time period. An evaluation procedure which accounted for both the quantity and quality of habitat was used to aid in assessing impacts resulting from the project. The Green Peter-Foster Project extensively altered or affected 7873 acres of land and river in the Santiam River drainage. Impacts to wildlife centered around the loss of 1429 acres of grass-forb vegetation, 768 acres of shrubland, and 717 acres of open conifer forest cover types. Impacts resulting from the Green Peter-Foster Project included the loss of critical winter range for black-tailed deer and Roosevelt elk, and the loss of year-round habitat for deer, upland game birds, river otter, beaver, pileated woodpecker, and many other wildlife species. Bald eagle and osprey were benefited by an increase in foraging habitat. The potential of the affected area to support wildlife was greatly altered as a result of the Green Peter-Foster Project. Losses or gains in the potential of the habitat to support wildlife will exist over the life of the project.

    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.

    Full Text Available En el presente artículo se analizan los conceptos de entramado, estrato y estratificación, en base al discurso narrado por Alison Smithson en su artículo “Strati e stratificazioni” de 1981, y a las obras en las que Alison y Peter Smithson trabajaron con los estratos y la estratificación, utilizando los entramados como medio para llevar a cabo su arquitectura. En este sentido, los Smithson –tras varias experimentaciones con estratos verticales que filtran y rompen la visión estática clásica, como en el pabellón de Ascot, 1955–, se plantean una exploración que les llevará a dos etapas consecutivas. La primera etapa está vinculada con los años setenta, donde los entramados fijos aparecían como filtros, velos, membranas, pieles insinuantes y protectoras, es decir, superficies planas tramadas –superpuestas entre sí o sobre diferentes espacios–, como se muestra en St. Hilda’s College, 1967-70. Una segunda etapa está relacionada con los años ochenta, donde esos entramados comienzan a separarse creando espacios intermedios –para ser ocupados con el arte de habitar– como en la exposición Christmas Hogmanay, 1980, y que, posteriormente, acabarán ramificándose tridimensionalmente como en el porche de Hexenhaus, 1984-2002. Estas reflexiones serán retomadas en la arquitectura contemporánea, como posibles nuevos referentes ante la creación de futuros espacios estratificados.

    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

    Full Text Available Juglans regia L. was the first exotic species of this genus to be cultivated at Peter the Great Botanical Garden of the V.L. Komarov Botanical Institute of RAS in Saint Petersburg – it was mentioned at M.M. Terekhovsky’s Catalogue in 1796. Firstly it was cultivated indoors. It was tested by E.L. Regel as early as in 1871 but unsuccessfully. It has been cultivated trustworthy outdoors since 1914. It was seriously frost damaging during the 20th century in cold winters with temperature below -25 oC, such as in 1955/56, 1968/69, 1978/79, аnd 1984/85. The winter of 1986/87 with absolute minimum temperature -34,7oC was very unfavourable, and many trees died after it. At present, the winter hardiness has increased with the warming of the climate. There are no frost damages at all or they are small and insignificant. The largest trees now reach 19 m high and 31 cm of trunk diameter in the age of 67 years old. The majority of trees produce fruits. Twenty trees of modern collection represent the five generations. The visible increasing of adaptation abilities is observed starting with the fifth generation. The trees of the fifth generation are good looking single-trunked trees without frost damages. Since 2014 they have been producing fruits, and subsequently this is possible to obtain plants of the sixth generation. Apparently the specimens of the fifth and the next generations are of special value to test at areas outside of the city to promote the distribution of the walnut in cultivation.

  20. The New Apostolic Reformation: The critical reflections of the ecclesiology of Charles Peter Wagner

    Full Text Available Charles Peter Wagner is a well-known missiologist and ecclesiologist of the latest era. He is the author, trainer and prayer warrior who founded the New Apostolic Reformation (NAR that seeks to establish a fourth house. The NAR is a heterodox movement in Protestant Christianity sometimes known as the apostolic-prophetic movement, commonly associated with both the Pentecostal and Charismatic churches worldwide since the beginnings of the 1990s. Central to their theology is their locus of dogma that the task of the church, under the leadership of the apostles and prophets, is to take dominion of the earth within Christendom (distinct from Catholicism, Protestantism and Orthodox Christianity. The ekklesia is the people of God, whether they are gathered in their congregations on Sunday as the nuclear Church, or scattered in the workplace Monday through Saturday as the extended Church. The extended Church, just like the nuclear Church, is founded on apostles and prophets, but in the extended Church these are the different people who operate differently under a different rule book. It is these extended church leaders who will be most effective in transforming society. Workplace apostles are called to take dominion in business, government, arts and entertainment, media, family and education. Panoramically, Wagner’s ecclesiology, like mainstream evangelical ecclesiology, is trinitarian, communal, missiological and eschatological in nature and character. The weaknesses on his ecclesiology include the notions of polity based on fivefold ministries, balance of power and authority on church leadership, phenomenological approach to texts, exegetical shortcomings, and secular models in ecclesiastical governance.

    The emergence of multi-drug resistant tuberculosis (MDR-TB) has become a major public health concern that threatens advances made in global TB control efforts. Though the problem is prevalent, it did not receive major attention to generate supportive evidence for the prevention and control of MDR-TB. The aim of this study was to identify predictors of MDR-TB in a national TB referral centre in Ethiopia. An unmatched, case-control study was conducted at St. Peter Hospital to assess risk factors associated with MDR-TB. The study included 103 culture proven, MDR-TB patients referred to the hospital during the study period (cases) and 103 randomly-selected TB patients with confirmed TB who turned negative after treatment (controls). Regressions analyses were used to determine the association of variables. The mean age among cases and controls was 30.5 (±9.26) and 34.73 (±11.28) years, respectively. The likelihood of having MDR-TB was 20.3 times higher among those who had a any previous history of TB treatment (AOR=20.3 [CI 5.13, 80.58]), 15.7 times higher among those who had TB more than once (AOR=15.7 [CI 4.18, 58.71]) compared those who had once, 6.8 times higher among those who had pulmonary TB (AOR=6.8 [CI 1.16, 40.17]) and 16.1 times higher for those who had experienced treatment with a Category II regimen (AOR=16.1 [CI 2.40, 108.56]). HIV infection was less common among cases than controls. This study concluded that special attention should be given to patients with a history of the following: TB more than once, presence of pulmonary TB, and used a Category II treatment regimen, as these were all determining factors for MDR-TB. Thus, this study urges the development and implementation of well-planned and integrated strategies for MDR-TB control and prevention in Ethiopia.

  2. Dislocations and Ecologies. The Disruption of the Urban Experience of London in Peter Ackroyd, Iain Sinclair and Gilbert & George

    Full Text Available London exerts attraction and repulsion upon travellers, writers and artists alike.Its past is overshadowed by the never-ending process of change, yet a closeinvestigation helps unveiling hidden parts of a collective memory. PeterAckroyd, Iain Sinclair and Gilbert & George have explored the memory ofLondon through the prism of cultural studies, psychogeography orcontemporary art. London: The Biography by Peter Ackroyd, Lights Out for theTerritory, London Orbital by Iain Sinclair and the 20 London E 1 Pictures byGilbert & George may serve as a basis for retrieving fragile realms of memory.We may wonder whether these realms cannot be likened to « ecology ofknowledge ». If ecology designates an environment regulated by specific rulesand mechanisms, what do “ecologies of knowledge” refer to in the urbancontext? Besides, the nature of the relationship between the experience ofLondon and the ecology of knowledge prompts questions. Does the experienceof London dislocate the artistic universes created by Peter Ackroyd, Iain Sinclairand Gilbert & George? Or do the artistic works partake in the dislocation ofurban experience? My contention in this paper is to unveil the ways in whichthe polymorphism of the city is translated into writerly and iconographic codes.As the understanding of the urban ecology keeps receding, similarly the worksadopt process and metamorphosis as structuring principles. First, thedestabilising exploration of London shall be assessed by its impact upon thephysical experience, and the renegotiation of concepts such as body,empiricism, and the spirit of the place. Then, the frustrating exploration ofLondon may be analysed through literary and artistic devices that echo thedislocation in the works. Eventually, these works will lead us to consider the dismemberingof the city body as the only means to the re-membering of London.

  9. Peters y España: edición musical y relaciones comerciales entre 1868 y 1892

    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

  13. An Efficient Image Encryption Scheme Based on a Peter De Jong Chaotic Map and a RC4 Stream Cipher

    Security is a vital issue in communication and storage of the images and encryption is one of the ways to ensure the security. This paper proposes an efficient image encryption scheme based on a Peter De Jong chaotic map and a RC4 stream cipher. A Peter De Jong map is employed to determine the initial keys for the RC4 stream generator and also during permutation stage. The RC4 stream generator is utilized to generate the pseudo random numbers for the pixel value rotation and diffusion operations. Each encryption round is comprised of three stages: permutation, pixel value rotation and diffusion. The permutation is based on scrambling the rows and columns, in addition, circular rotations of the rows and columns in alternate orientations. The second stage circularly rotates each and every pixel value by utilizing M × N pseudo random numbers. The last stage carries out the diffusion twice by scanning the image in two different ways. Each of the two diffusions accomplishes the diffusion in two orientations (forward and backward) with two previously diffused pixels and two pseudo random numbers. The security and performance of the proposed method is assessed thoroughly by using key space, statistical, differential, entropy and performance analysis. Moreover, two rounds of the call to the encrypt function provide the sufficient security. The experimental results show that the proposed encryption scheme is computationally fast with high security.

    Rocco, Richard M

    2017-02-01

    John P Peters is considered one of the founders of modern clinical chemistry. In more than 200 research articles, he brought clinical biochemistry to the bedside, advancing the use of laboratory medicine in diagnosis and disease management. His two-volume landmark textbook Quantitative Clinical Chemistry, coauthored with Donald Dexter van Slyke (1883-1971) and released in 1931-1932, defined clinical chemistry as a distinct professional discipline within medicine. A three-volume revision was begun in 1937. Peters took on the task of revising Volumes I and II but never finished Volume II. His outspoken public advocacy for social reform, world peace, and universal health care made him a target in the era of McCarthyism. Three times between 1949 and 1953 he was brought before the Loyalty Review Board with charges of being a communist and a sympathetic supporter of subversive organizations. According to his family, the turmoil of the McCarthyism persecution shortened his life and prevented him from completing the one thing he wanted to do in his professional life, finish the revision of his landmark clinical chemistry textbook.

    Peter Mark Roget (1779-1869) is best known for his Thesaurus, a project completed late in his long life. He trained as a physician, practiced medicine, and was interested in many branches of science. Much of his life was dedicated to the systematization of knowledge and identifying relationships. Although not an experimentalist in the modern sense of the word, he contributed to "neuroscience" in journal and encyclopaedia articles, as well as in books and lectures. He wrote extensively on comparative physiology, sensory systems, phrenology, optics, and various disorders affecting the nervous system. He viewed his two-volume Bridgewater Treatise of 1834 as his most significant achievement, turning to physiology and comparative anatomy to argue that God's existence can be seen in how living forms and their components are designed. Roget was active in many scholarly organizations, most notably the Royal Society of London, where he served for more than two decades as its secretary before "retiring" to pursue his Thesaurus.

    Full Text Available The Saint Peter and Saint Paul Archipelago in the central tropical Atlantic, is an important ground of whale sharks that are commonly sighted throughout the year close to the fishing boats in the adjacencies of the islands. In sightings reported between February 2000 and November 2005, the lengths of the individuals ranged between 1.8 to 14.0 m. The causes of these concentrations in the archipelago are still unclear, once there are no upwellings and plankton concentrations for feeding, and no reproductive activities were reported. Nevertheless, they could be associated to the spawning period of the abundant flying fishes, mainly in the first semester, when sightings were more frequent.

    2014-01-01

    R. C. Carrington, C. H. F. Peters, and W. de la Rue observed the sunspots in the second half of the 19th century, determining their heliographic positions between 1853 and 1870, before the establishment of the solar program of the Royal Greenwich Observatory. The large tables of sunspot positions included in the catalogues published by these observers have recently been converted to a machine readable format. The present work analyses this data by calculating the sunspot group velocities for each observer. These results are then fitted with a differential rotation law to compare the data of the three observers with each other and with the results published by other authors. Finally, a study is made of the possible relationship between the sunspot group areas as determined by de la Rue and the corresponding sunspot group velocities.

    Midgley, Nick

    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 The massive, pragmatic and intellectual work by Peter Stein on the Oresteia of Aeschylus perfectly summarizes the German director’s conception of ‘classic’. This essay reviews the twenty-years period which started with the first experimental approach to ancient tragedy by the Schaubühne to the staging of the trilogy in Moscow in 1994. In his work, Stein investigates the origins of western theatre, compares the role of gestures and words at the dawn of theatre with that of the contemporary age, and then moves, in line with the evolution of the Aeschylus trilogy plot, to the study of the purely political connotation of the text. Precisely the post-soviet Russia represented the ideal setting where to reproduce the rite of dismissal of high hierarchies, whether of divine nature or not, and the affirmation of the new democratic system.L’imponente lavoro pratico e intellettuale di Peter Stein sull’Orestea di Eschilo riassume in maniera esemplare il pensiero del regista tedesco riguardo all’idea di ‘classico’. Nel saggio si traccia il percorso lungo i vent’anni che vanno dal primo sperimentale approccio alla tragedia antica da parte del gruppo della Schaubühne fino alla messinscena moscovita della trilogia del 1994. Nel suo lavoro Stein riflette sulle origini del teatro in Occidente, sul ruolo del gesto e della parola agli albori del teatro e in epoca contemporanea, spostando poco a poco lo sguardo, in linea con l’evoluzione dell’intreccio della trilogia eschilea, sul significato prettamente politico del testo. Proprio la Russia postcomunista si qualifica allora luogo ideale in cui ripetere il rito di destituzione di ogni ordine superiore (ove il termine sia da intendere nel senso più lato, non solo divino e affermazione del nuovo sistema democratico.

  6. THE THRONE OF PETER DURING THE FIRST CENTURIES: FROM THE EARLIEST TIMES TO THE SEPARATION OF THE PAPACY FROM BYZANTIUM

    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.

    1997-01-01

    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

    Although coloniality is widespread among mammals, it is still not clear what factors influence composition of social groups. As animals need to adapt to multiple habitat and environmental conditions throughout their range, variation in group composition should be influenced by adaptive adjustment to different ecological factors. Relevant to anthropogenic disturbance, increased habitat modification by humans can alter species' presence, density, and population structure. Therefore, it is important to understand the consequences of changes to landscape composition, in particular how habitat modification affects social structure of group-forming organisms. Here, we combine information on roosting associations with genetic structure of Peter's tent-roosting bats, Uroderma bilobatum to address how different habitat characteristics at different scales affect structure of social groups. By dividing analyses by age and sex, we determined that genetic structure was greater for adult females than adult males or offspring. Habitat variables explained 80% of the variation in group relatedness (mainly influenced by female relatedness) with roost characteristics contributing the most explained variation. This suggests that females using roosts of specific characteristics exhibit higher relatedness and seem to be philopatric. These females mate with more males than do more labile female groups. Results describe ecological and microevolutionary processes, which affect relatedness and social structure; findings are highly relevant to species distributions in both natural and human-modified environments.

    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)

  1. Peter Pan functions independently of its role in ribosome biogenesis during early eye and craniofacial cartilage development in Xenopus laevis.

    The Xenopus oocyte possesses a large maternal store of ribosomes, thereby uncoupling early development from the de novo ribosome biosynthesis required for cell growth. Brix domain-containing proteins, such as Peter Pan (PPan), are essential for eukaryotic ribosome biogenesis. In this study, we demonstrate that PPan is expressed maternally as well as in the eye and cranial neural crest cells (NCCs) during early Xenopus laevis development. Depletion of PPan and interference with rRNA processing using antisense morpholino oligonucleotides resulted in eye and cranial cartilage malformations. Loss of PPan, but not interference with rRNA processing, led to an early downregulation of specific marker genes of the eye, including Rx1 and Pax6, and of NCCs, such as Twist, Slug and FoxD3. We found that PPan protein is localized in the nucleoli and mitochondria and that loss of PPan results in increased apoptosis. These findings indicate a novel function of PPan that is independent of its role in ribosome biogenesis.

  2. The Wnt Target Protein Peter Pan Defines a Novel p53-independent Nucleolar Stress-Response Pathway.

    Proper ribosome formation is a prerequisite for cell growth and proliferation. Failure of this process results in nucleolar stress and p53-mediated apoptosis. The Wnt target Peter Pan (PPAN) is required for 45 S rRNA maturation. So far, the role of PPAN in nucleolar stress response has remained elusive. We demonstrate that PPAN localizes to mitochondria in addition to its nucleolar localization and inhibits the mitochondrial apoptosis pathway in a p53-independent manner. Loss of PPAN induces BAX stabilization, depolarization of mitochondria, and release of cytochrome c, demonstrating its important role as an anti-apoptotic factor. Staurosporine-induced nucleolar stress and apoptosis disrupt nucleolar PPAN localization and induce its accumulation in the cytoplasm. This is accompanied by phosphorylation and subsequent cleavage of PPAN by caspases. Moreover, we show that PPAN is a novel interaction partner of the anti-apoptotic protein nucleophosmin (NPM). PPAN depletion induces NPM and upstream-binding factor (UBF) degradation, which is independent of caspases. In summary, we provide evidence for a novel nucleolar stress-response pathway involving PPAN, NPM, and BAX to guarantee cell survival in a p53-independent manner. © 2015 by The American Society for Biochemistry and Molecular Biology, Inc.

    Mesophotic reef fish assemblages (30-90 m depth) of the small and remote St. Peter and St. Paul's Archipelago (SPSPA), Mid-Atlantic Ridge, Brazil, were characterized using remotely operated vehicles. Ordination analyses identified distinct fish assemblages in the upper (30-50 m) and lower (50-90 m) mesophotic zones, the former characterized by high abundances of species that are also abundant at euphotic reefs ( Caranx lugubris, Melichthys niger, Stegastes sanctipauli and Chromis multilineata) and the latter dominated by two mesophotic specialists ( Prognathodes obliquus and Chromis enchrysura). Planktivores dominated fish assemblages, particularly in the upper mesophotic zone, possibly due to a greater availability of zooplankton coming from the colder Equatorial Undercurrent in mesophotic depths of the SPSPA. Turf algae, fleshy macroalgae and scleractinian corals dominated benthic assemblages between 30 and 40 m depth, while bryozoans, black corals and sponges dominated between 40 and 90 m depth. Canonical correspondence analysis explained 74 % of the relationship between environmental characteristics (depth, benthic cover and complexity) and structure of fish assemblages, with depth as the most important independent variable. Juveniles of Bodianus insularis and adults of P. obliquus and C. enchrysura were clearly associated with branching black corals ( Tanacetipathes spp.), suggesting that black corals play key ecological roles in lower mesophotic reefs of the SPSPA. Results from this study add to the global database about mesophotic reef ecosystems (MREs) and provide a baseline for future evaluations of possible anthropogenic and natural disturbances on MREs of the SPSPA.

  4. Euthanasia and John Paul II's "silent language of profound sharing of affection:" why Christians should care about Peter Singer.

    Jeffreys, Derek S

    2001-12-01

    Peter Singer's recent appointment to Princeton University created considerable controversy, most of it focused on his proposal for active euthanasia of disabled infants. Singer articulates utilitarian ideas that often appear in public discussions of euthanasia. Drawing on Pope John Paul II's work on ethics and suffering, I argue that Singer's utilitarian theory of value is impoverished. After introducing the Pope's ethic based on the imago dei, I discuss love as self-gift. I show how this concept supports a theory of value in which spiritual goods are preeminent over material goods. I then describe how suffering reveals spiritual goods, discussing how participation in Christ's suffering can alter our perception of value. I also consider how communal responses to suffering provide opportunities for self-giving. Third, I consider Singer's proposal for killing infants with hemophilia, arguing that it arbitrarily ignores spiritual goods. I then discuss proposals to kill anencephalic infants, discussing how parental responses to their suffering can demonstrate an extraordinary love in seemingly hopeless circumstances. I conclude by calling for a more sustained social response to euthanasia initiatives.

    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.

  6. A variation on forced migration: Wilhelm Peters (Prussia via Britain to Turkey) and Muzafer Sherif (Turkey to the United States).

    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.

    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.

    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 contributions of Sir Peter Mansfield to MRI are rooted in solid state NMR. I summarize some of the important contributions of Sir Peter to that field, provide a glimpse of the state of the art in multiple-pulse line-narrowing in the early 1970s, and indicate how the earliest MRI efforts at Nottingham flowed from solid state NMR. These line-narrowing methods, providing control over the Hamiltonian governing the dynamics of nuclear spins, continue to evolve and to find new uses.

    The novels Peter Pan and Peter Pan in Kensington Gardens by the Scottish writer James Barric were created in the early 20th century. The protagonist Peter Pan has since then become a classic character in the woad literary corridor. He is much more than a boy that cannot grow up, more importantly; he is a boy that refuses to grow up, rendering him distinct from all the other children. Refusing to grow up is more than a life posture, rather; it is a life choice. The mythological and archetypal ap- proaches are employed to find the archetypes behind Peter Pan in the Hellenic mythos and Christian culture, so as to reveal his reasons for making such a different life option.%苏格兰作家詹姆斯·巴里的小说《彼得·潘》和《彼得·潘在肯辛顿公园》创作于20世纪初期,主人公小飞侠彼得·潘成为世界文学长廊上的一个经典形象。他不仅仅是一个长不大的小男孩,还是一个拒绝长大的小男孩,使他有着迥异于其他儿童的特点。拒绝长大既是一种生活姿态,更是一种人生选择。运用神话原型批评理论,找到彼得·潘在古希腊神话和基督教文化中的原型,试图揭示他与众不同的人生抉择的原因。

    The monitoring of hazardous natural processes In coastal and shelf zone of the gulf of Peter the Great (sea of Japan) in 2012-2013 was made by staff of the Gramberg Institute VNIIOKEANGEOLOGIA . The complex of field researches are: - laser scanning beaches (tachometer Leica HDS 3000); - echosounding underwater coastal slope (sounder-Navigator LCX-37C); - high-frequency acoustic profiling (GeoPulse Subbotom Profilier); - hydromagnetic shooting magnetometer SeaSPY Marine Magnetics; - sonar shooting (complex GEO-CM-MAX); - research of the water column (sounding and sampling); - bottom sampling, including gasgeochemical shooting. The result of this work is the following conclusions: 1. As the shore, and the underwater slope of the district are experiencing the preemptive destruction, the areas of which are quantitative and spatially prevail over the stable and accumulate zones (except the shores of the inland parts of bays and gulfs). 2. The rate of destruction of coast in the Gulf of Peter the Great is 1-20 meters for 100 years, that could pose a serious danger to the population and infrastructure. 3. Number of gasgeochemical anomalies on the shelf of the Gulf of Peter the Great spatially associated with fault lines, limiting blocks of the earth's crust within shelf. 4. Perhaps it is these faults are of the greatest seismic hazard in the moment. 5. Danger of themselves gas emissions The following significant hazards and risks to the region have been studied: seismic and tsunami destruction of shore, gas emissions, technogenic pollution.
