Pine Island Glacier (Antarctica) velocities from Landsat7 images between 2001 and 2011: FFT-based image correlation for images with data gaps
Authors: Warner Roland C. , Roberts Jason L.
Published: June 2013

Remote sensing of ice motion by tracking displacement of surface features is a valuable tool in glaciology. Efficient image feature-tracking programs, such as IMCORR, based on fast Fourier transform methods can produce misleading correlations if there are data gaps in either or both of the reference and search images. This is particularly problematic if the data gaps are regular in character, such as for Landsat7 images collected after the failure of the Scan Line Corrector (SLC-off images). We demonstrate that this situation can be alleviated by filling the data gaps with suitably chosen random data. We modified IMCORR to achieve this automatically (source code is included), but generic image-processing software could be used to modify inputs for other correlation packages. We test our method using images of Pine Island Ice Shelf, Antarctica, and document the acceleration of the velocity field for the floating extension of Pine Island Glacier over the decade 2001–11. We also combine our velocities with recent NASA Operation IceBridge ice thickness data from CReSIS to estimate the basal melt rates.
Meristem Development and its Relation to Endogenous GA3 and IAA Contents During Floral Bud Differentiation in Broccoli
Authors: Jiang Xinmei , Yu Xihong , Li Dan
Published: June 2013

The effects of three temperature treatments on morphological changes in the apical meristem and contents of GA3 and IAA in leaves during floral bud differentiation in early maturing cultivar of broccoli were studied. Plants went through every stage of flower-bud differentiation at day/night temperatures of 17.3±1/9.3±1°C. At 21.3±1/13.3±1°C, floral bud development ceased after primary axillary scape primordium differentiation and apical meristem entered a reversion stage. The apical meristem remained in the vegetative growth phase in plants growing at 25.3±1/17.3±1°C. Leaf GA3 contents started to increase while IAA contents started to decrease when plants entered the flower bud initiation stage. GA3 content was high and IAA content was low during all stages of axillary scape primordium differentiation.Key words: Meristem development; Broccoli; Apical meristem; GA3; IAADOI: http://dx.doi.org/10.3329/jbas.v35i1.7966 Journal of Bangladesh Academy of Sciences, Vol.35, No.1, 1-6, 2011

Authors: Begum Mahfuza , Mollah AS , Zaman MA , Haq M , Rahman AKM Mizanur
Published: June 2013

Different essential radiographic parameters were studied in order to assess radiographic image quality ensuring reduction of radiation exposure in some diagnostic X-ray facilities of Bangladesh. Different parameters for developing and fixing liquid were investigated in order to eliminate improper film processing techniques. General information about intensifying screen, radiography and mammography film was also collected. X-ray tube voltage, output radiation dose and exposure time for diagnostic X-ray machines were tested to achieve significant dose reduction without loss of diagnostic information. It is found that output radiation dose varies in different diagnostic X-ray installations. 70% X-ray installations achieve the recommended value for tube voltage while 87.5% measure the exposure time appropriately. Radiation dose level at patient waiting room, dark room and around control panel was also measured. About 92.5, 85 and 77.5% installations show their results within the acceptance limit at these positions respectively which provide radiation safety for patients, workers and public in diagnostic radiology.DOI: http://dx.doi.org/10.3329/jbas.v35i1.7967Journal of Bangladesh Academy of Sciences, Vol.35, No.1, 7-17, 2011

Authors: Mondol MN , Chamon AS , Faiz B , Elahi SF
Published: June 2013

The Tejgaon industrial area is located within the Dhaka City Corporation and is about 5 km north of the city centre. Heavy metal concentration at different sampling points varied in different seasons and the maximum amount was observed in the dry season (January). Total Fe, Pb, Cd, Mn, Ni, Zn, Cu and Cr concentrations in water samples during dry season ranged from 0.11 - 2.78, 0.733 - 2.171, 0.05 - 0.1, 0.019 - 0.34, 0.02 - 0.17, 0.01 - 0.348, 0.10 - 0.846, and 0.02 - 0.09 mg/l respectively. The present study revealed that the pollution level was very much alarming and increasing slowly day by day. According to WHO guidelines, during both wet and dry seasons 100% water samples were found in the group of "in excess of tolerable level" for Pb (0.01 mg/l). 63, 42, 79, 58 and 95% water samples were found in the group of 'in excess of tolerable level' during dry season for Cu, Ni, Cd, Cr and Mn. Only 26% of the plant samples had Ni (< 20 mg/kg) in the normal range and 74% (? 20 - 30 mg/kg) plant samples were found in the group of "in excess of tolerable level" during dry season which was 63% (? 20 - 30 mg/kg) during wet season. Cadmium and Pb in plant samples found in the group of "in excess of tolerable level" was 26, 79% (> 10 mg kg), and 33, 59% (> 20 mg/kg) during wet and dry season, respectively. Plant samples accumulated more and tolerated higher amounts of Cr during dry season. Average concentration of Fe, Mn and Zn at different locations and plant species were 220.81, 279.33 and 239.81 mg/kg and 212.0, 313.43 and 159.19 mg/kg during wet and dry seasons, respectively. Kalmi, water hyacinth, grass (in wet season) and Boro rice, Cabbage (in dry season) accumulated the maximum concentration of Fe and Mn. In the rainy season the pollution was lower because of heavy rainfall and flushed out through the canal into the adjoining vast flood zone.DOI: http://dx.doi.org/10.3329/jbas.v35i1.7968Journal of Bangladesh Academy of Sciences, Vol.35, No.1, 19-41, 2011
Sintering Temperature Dependent Permeability of Nanocrystalline Ni0.20Cu0.30Zn0.50Fe2O4 Ferrite
Authors: Rahman ML , Khan MHR , Mahmud ST , Hossain AKM Akther
Published: June 2013

The spinel ferrite of Ni0.20Cu0.30Zn0.50Fe2O4 was studied at room temperature using X-ray diffraction pattern prepared by auto combustion technique. The analysis of the XRD patterns showed that the sample has a single phase cubic spinel structure. The bulk density, average grain size and initial permeability increase with increasing sintering temperature up to a optimum temperature. Beyond that temperature all those properties decreases. The value of relative quality factor decreases with increasing sintering temperature. The DC magnetization measurement showed that at room temperature the sample is in ferrimagnetic state. The number of Bohr magneton, n(?B), Néel temperature, TN, and the field at which saturation occurs were also calculated and possible explanation for the observed characteristics of microstructure, initial permeability, DC magnetization, and Néel temperature of the studied sample are presented.DOI: http://dx.doi.org/10.3329/jbas.v35i1.7972Journal of Bangladesh Academy of Sciences, Vol.35, No.1, 67-75, 2011
Toward a (Re)signification of Cultural Hybridity: Guji Guji and Master Mason
Authors: Wu Andrea Mei-Ying
Published: June 2013

Drawing on the theories of M. M. Bakhtin and Homi Bhabha, among others, this paper examines the textual discourse of cultural hybridity in two paradigmatic picturebooks, Guji Guji (2003) and Master Mason (2004), published in Taiwan in the first decade of the twenty-first century, with a close look at the socio-political milieu of Taiwan at the turn of the millennium. The story of Guji Guji deals with the dilemma that a hybrid self inevitably comes to face and negotiate and the ambivalences associated with the discourse of culture's in-between, whereas Master Mason pivots on the tension and contestation between the past and the present and views hybridity as a transgressive power to counter, disrupt, or subvert tradition, as well as to bring in a mosaic representation and improvisational negotiation of cultures and ideas. Differing in subject matter and art style, both picturebooks, nevertheless, substantially work to interpret and interrogate the complex and often contentious negotiations and representations of cultural crossings and mixings.
Petrifying Attachments: Fear and Safety in Jeanette Winterson's Tanglewreck and The Battle of the Sun
Authors: Armitt Lucie
Published: June 2013

This article focuses on Jeanette Winterson's two most extended works of fiction for children, Tanglewreck and The Battle of the Sun, identifying them as narratives of longing and adventure engaging directly with questions of childhood fear and safety. In 2007 I wrote an article on Winterson's adult fiction which focused on her use of vertical imagery. Using such vertiginous drops, I argued, Winterson explores the perilous opportunities afforded by disengaging from a woman-centred storytelling tradition, thus enabling her to ‘go it alone’. In Tanglewreck and The Battle of the Sun, these vertical images return and are again connected with questions of attachment and disengagement, yet now with an increasingly overt agenda of negotiating maternal separation anxiety. In Winterson's 2011 memoir, Why Be Happy When You Could Be Normal?, the journey of the first-person narrator, as she travels from child to adulthood, is shrouded in fears linked to lost origins and a safe sense of belonging. As this article shows, these are also the issues facing Silver and Jack, the child protagonists of Tanglewreck and The Battle of the Sun.

Not Only Forgotten but Never Known: The Life and Contributions of Jiří Langer
Authors: Schulman Martin A.
Published: June 2013

Jiří Langer was one of the first contributors to a psychoanalytic understanding of Jewish rituals and Jewish mysticism through his book The Eroticism of Kabbalah and two articles published in Imago in the 1920s and 1930s. He also was a practising Chassidic Jew, the only one to publish in an analytic journal until the late twentieth century. This article deals with his transition from an assimilated Prague family to a Belzer Chassid, his interpretation of Jewish symbols through a Freudian lens as well as his friendship with Kafka. The article also tries to understand the appeal of Chassidism as an outlet for his homosexual desires and as a regulator of his self-esteem. Langer's life, although short, was a fascinating journey of self-discovery and an attempt to synthesize Jewish mysticism, cultural anthropology and Freudian theory.
Wilhelm Stekel's Dialogue with Sigmund Freud: The Case for Brief Therapy and the Symbolism of Dreams
Authors: Timms Edward
Published: June 2013

Responding to recent publications by Clark-Lowes, and by Bos and Groenendijk, this article suggests that a systematic biography of Wilhelm Stekel, acknowledging his pioneering contributions to dream interpretation and brief psychotherapy, is long overdue. His interactions with Freud should be seen as an implicit dialogue, rather than a confrontation. Among the factors that have affected Stekel's reputation is an unresolved contradiction between the optimism of his writings about public health and the pessimism of his clinical findings. At the heart of his work lies the tension between Eros and Thanatos, which he explored so imaginatively in Die Sprache des Traumes (The Language of Dreams).
Systems Biology — the Broader Perspective
Authors: Bard Jonathan
Published: June 2013

Systems biology has two general aims: a narrow one, which is to discover how complex networks of proteins work, and a broader one, which is to integrate the molecular and network data with the generation and function of organism phenotypes. Doing all this involves complex methodologies, but underpinning the subject are more general conceptual problems about upwards and downwards causality, complexity and information storage, and their solutions provide the constraints within which these methodologies can be used. This essay considers these general aspects and the particular role of protein networks; their functional outputs are often the processes driving phenotypic change and physiological function—networks are, in a sense, the units of systems biology much as proteins are for molecular biology. It goes on to argue that the natural language for systems-biological descriptions of biological phenomena is the mathematical graph (a set of connected facts of the general form  [process]  (e.g.,  [activates] ). Such graphs not only integrate events at different levels but emphasize the distributed nature of control as well as displaying a great deal of data. The implications and successes of these ideas for physiology, pharmacology, development and evolution are briefly considered. The paper concludes with some challenges for the future.

Published: June 2013

It is important to understand the physicochemical mechanisms that are responsible for the morphological changes in the cell membrane in the presence of various stimuli such as osmotic pressure. Lipid rafts are believed to play a crucial role in various cellular processes. It is well established that Ctb (Cholera toxin B subunit) recognizes and binds to GM1 (monosialotetrahexosylganglioside) on the cell surface with high specificity and affinity. Taking advantage of Ctb-GM1 interaction, we examined how Ctb and GM1 molecules affect the dynamic movement of liposomes. GM1 a natural ligand for cholera toxin, was incorporated into liposome and the interaction between fluorescent Ctb and the liposome was analyzed. The interaction plays an important role in determining the various surface interaction phenomena. Incorporation of GM1 into membrane leads to an increase of the line tension leading to either rupture of liposome membrane or change in the morphology of the membrane. This change in morphology was found to be GM1 concentration specific. The interaction between Ctb-GM1 leads to fast and easy rupture or to morphological changes of the liposome. The interactions of Ctb and the glycosyl chain are believed to affect the surface and the curvature of the membrane. Thus, the results are highly beneficial in the study of signal transduction processes.
Conopeptides from Cape Verde Conus crotchii
Authors: Neves Jorge , Campos Alexandre , Osório Hugo , Antunes Agostinho , Vasconcelos Vitor
Published: June 2013

Marine Cone snails of the genus Conus contain complex peptide toxins in their venom. Living in tropical habitats, they usually use the powerful venom for self-defense and prey capture. Here, we study Conus crotchii venom duct using a peptide mass-matching approach. The C. crotchii was collected on the Cape Verde archipelago in the Boa Vista Island. The venom was analyzed using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS). About 488 molecular masses between 700 Da and 3000 Da were searched bymatching with known peptide sequences from UniProtKB protein sequence database. Through this method we were able to identify 12 conopeptides. For validation we considered the error between the experimental molecular mass (monoisotopic) and the calculated mass of less than 0.5 Da. All conopeptides detected belong to the A-, O1-, O2-, O3-, T- and D-superfamilies, which can block Ca2+ channels, inhibit K+ channels and act on nicotinic acetylcholine receptors (nAChRs). Only a few of the detected peptides have a 100% UniProtKB database similarity, suggesting that several of them could be newly discovered marine drugs.
Applications of Azide-Based Bioorthogonal Click Chemistry in Glycobiology
Authors: Zhang Xiu , Zhang Yan
Published: June 2013

Click chemistry is a powerful chemical reaction with excellent bioorthogonality features: biocompatible, rapid and highly specific in biological environments. For glycobiology, bioorthogonal click chemistry has created a new method for glycan non-invasive imaging in living systems, selective metabolic engineering, and offered an elite chemical handle for biological manipulation and glycomics studies. Especially the [3 + 2] dipolar cycloadditions of azides with strained alkynes and the Staudinger ligation of azides and triarylphosphines have been widely used among the extant click reactions. This review focuses on the azide-based bioorthogonal click chemistry, describing the characteristics and development of these reactions, introducing some recent applications in glycobiology research, especially in glycan metabolic engineering, including glycan non-invasive imaging, glycomics studies and viral surface manipulation for drug discovery as well as other applications like activity-based protein profiling and carbohydrate microarrays.
Immunomodulatory Effect of Stichopus japonicus Acid Mucopolysaccharide on Experimental Hepatocellular Carcinoma in Rats
Authors: Song Yang , Jin Shou-Jie , Cui Lian-Hua , Ji Xiao-Jun , Yang Fu-Guo
Published: June 2013

Stichopus japonicus acid mucopolysaccharide (SJAMP) is an important biologically active compound that can be extracted from the body wall of the sea cucumber. The present study investigated the anti-tumor and immunomodulatory effects of SJAMP in an experimental hepatocellular carcinoma (HCC) model in rats. Three doses of SJAMP (17.5 mg/kg, 35 mg/kg, and 70 mg/kg administered 5 days/week via oral gavage) were given to rats with diethylnitrosamine (DEN)-induced HCC. SJAMP treatment significantly inhibited DEN-induced HCC by reducing both the number and mean volume of nodules, decreasing serum a-fetoprotein (AFP) levels and proliferating cell nuclear antigen (PCNA) expression in liver, and increasing p21 expression. Furthermore, SJAMP decreased the serum levels of ALT, AST, GGT and TNF-α and increased serum IL-2. SJAMP administration also improved indices of spleen and thymus function and improved both macrophage phagocytosis and NK cell-mediated tumoricidal activity. Moreover, CD3+ and CD4+ T lymphocyte levels recovered significantly and the CD4+/CD8+ T cell ratio normalized in a dose-dependent manner. In conclusion, SJAMP effectively inhibited the growth of HCC through the stimulation of immune organs and tissue proliferation, leading to the enhancement of cellular immunity pathways in rats.
Testing the Application of Terrestrial Laser Scanning to Measure Forest Canopy Gap Fraction
Authors: Ramirez F. , Armitage Richard , Danson F.
Published: June 2013

Terrestrial laser scanners (TLS) have the potential to revolutionise measurement of the three-dimensional structure of vegetation canopies for applications in ecology, hydrology and climate change. This potential has been the subject of recent research that has attempted to measure forest biophysical variables from TLS data, and make comparisons with two-dimensional data from hemispherical photography. This research presents a systematic comparison between forest canopy gap fraction estimates derived from TLS measurements and hemispherical photography. The TLS datasets used in the research were obtained between April 2008 and March 2009 at Delamere Forest, Cheshire, UK. The analysis of canopy gap fraction estimates derived from TLS data highlighted the repeatability and consistency of the measurements in comparison with those from coincident hemispherical photographs. The comparison also showed that estimates computed considering only the number of hits and misses registered in the TLS datasets were consistently lower than those estimated from hemispherical photographs. To examine this difference, the potential information available in the intensity values recorded by TLS was investigated and a new method developed to estimate canopy gap fraction proposed. The new approach produced gap fractions closer to those estimated from hemispherical photography, but the research also highlighted the limitations of single return TLS data for this application.
Recovery of Odorants from an Olfactometer Measured by Proton-Transfer-Reaction Mass Spectrometry
Authors: Hansen Michael , Adamsen Anders , Feilberg Anders
Published: June 2013

The aim of the present study was to examine the recovery of odorants during the dilution in an olfactometer designed according to the European standard for dynamic olfactometry. Nine odorants in the ppmv-range were examined including hydrogen sulfide, methanethiol, dimethyl sulfide, acetic acid, propanoic acid, butanoic acid, trimethylamine, 3-methylphenol and n-butanol. Each odorant was diluted in six dilution steps in descending order from 4,096 to 128 times dilutions. The final recovery of dimethyl sulfide and n-butanol after a 60-second pulse was only slightly affected by the dilution, whereas the recoveries of the other odorants were significantly affected by the dilution. The final recoveries of carboxylic acids, trimethylamine and 3-methylphenol were affected by the pulse duration and the signals did not reach stable levels within the 60-second pulse, while sulfur compounds and n-butanol reach a stable signal within a few seconds. In conclusion, the dilution of odorants in an olfactometer has a high impact on the recovery of odorants and when olfactometry is used to estimate the odor concentration, the recoveries have to be taken into consideration for correct measurements.
In situ Measurements of Phytoplankton Fluorescence Using Low Cost Electronics
Authors: Leeuw Thomas , Boss Emmanuel , Wright Dana
Published: June 2013

Chlorophyll a fluorometry has long been used as a method to study phytoplankton in the ocean. In situ fluorometry is used frequently in oceanography to provide depth-resolved estimates of phytoplankton biomass. However, the high price of commercially manufactured in situ fluorometers has made them unavailable to some individuals and institutions. Presented here is an investigation into building an in situ fluorometer using low cost electronics. The goal was to construct an easily reproducible in situ fluorometer from simple and widely available electronic components. The simplicity and modest cost of the sensor makes it valuable to students and professionals alike. Open source sharing of architecture and software will allow students to reconstruct and customize the sensor on a small budget. Research applications that require numerous in situ fluorometers or expendable fluorometers can also benefit from this study. The sensor costs US$150.00 and can be constructed with little to no previous experience. The sensor uses a blue LED to excite chlorophyll a and measures fluorescence using a silicon photodiode. The sensor is controlled by an Arduino microcontroller that also serves as a data logger.
Gait-Based Person Identification Robust to Changes in Appearance
Authors: Iwashita Yumi , Uchino Koji , Kurazume Ryo
Published: June 2013

The identification of a person from gait images is generally sensitive to appearance changes, such as variations of clothes and belongings. One possibility to deal with this problem is to collect possible subjects’ appearance changes in a database. However, it is almost impossible to predict all appearance changes in advance. In this paper, we propose a novel method, which allows robustly identifying people in spite of changes in appearance, without using a database of predicted appearance changes. In the proposed method, firstly, the human body image is divided into multiple areas, and features for each area are extracted. Next, a matching weight for each area is estimated based on the similarity between the extracted features and those in the database for standard clothes. Finally, the subject is identified by weighted integration of similarities in all areas. Experiments using the gait database CASIA show the best correct classification rate compared with conventional methods experiments.
Motivations for Proactive Environmental Management
Authors: Khanna Madhu , Speir Cameron
Published: June 2013

This paper examines the extent to which there are differential incentives that motivate the adoption of environmental management practices (EMPs) and pollution prevention (P2) methods. We analyze the role of internal drivers such as managerial attitudes towards the environment and external pressures using both observed characteristics of facilities and perceived pressures. We estimate a structural equation model using survey data from facilities in Oregon that involves simultaneous estimation of the latent dependent and explanatory variables and the two regression equations explaining adoption behavior of EMPs and P2. We find that perceived regulatory pressures and managerial attitudes have a statistically significant impact on the adoption of both EMPs and P2 practices, while market pressures were significant in influencing the adoption of EMPs but not P2 methods. Furthermore; we find that both external regulatory pressures and internal managerial attitudes had a larger impact in motivating adoption by facilities that did not view environmental issues as being a significant concern as compared to facilities that did.
Decision Support Systems for Water Resources Management in Developing Countries: Learning from Experiences in Africa
Authors: Giupponi Carlo , Sgobbi Alessandra
Published: June 2013

Decision support system (DSS) tools are rather popular in the literature on water resources management. The European Project “Splash” conducted a survey of the literature and of DSS implementation in developing countries with specific reference on Africa. Experts in the field were consulted through an ad hoc questionnaire and interviews. The results of the survey indicate that the exchange of experiences amongst projects with similar objectives or even the same case study is very limited, with a tendency towards restarting every time from scratch. As a consequence, it seems that DSS developments have produced only limited positive impacts. Most experts contacted shared either the frustration deriving from the limited impacts on intended end-users, who rarely used the tool after the project end, or in the case of ongoing projects, the preoccupation for future maintenance. Responses from the questionnaires indicate that priority efforts should not focus on developing the tools, but rather on improving the effectiveness and applicability of integrated water resource management legislative and planning frameworks, training and capacity building, networking and cooperation, harmonization of transnational data infrastructures and, very importantly, learning from past experiences and adopting enhanced protocols for DSS development.

Authors: Haberl Annette , Johnson Margaret , Dominguez Stephanie , Miralles Celia , Monforte Antonella d'Arminio , Anderson Jane
Published: June 2013

Across Europe, women account for one-third of new diagnoses of HIV and yet data to guide the treatment of women living with HIV are limited, a situation largely due to under-representation of women in clinical trials. SHE is a European initiative co-led by a medical faculty of HIV physicians and a community peer-support faculty of women living with HIV, with the common goal of improving the outcomes and quality of life of women living with HIV.

In 2011, two meetings of the SHE medical faculty and invited specialists in HIV medicine were convened to discuss the situation of and clinical care for women living with HIV in Europe. At the first meeting, available data on women living with HIV in Europe were reviewed and knowledge gaps were identified and prioritized. At the second meeting, delegates agreed upon next steps required to address the highest priority challenges. The most important requirements that were identified included additional, up-to-date guidance on clinical management of women (including pregnant women) living with HIV, greater coordination of European country registries of antiretroviral therapy in pregnant women, and generation of more gender-specific clinical data. The current article introduces the five key SHE topics pertaining to the care of women living with HIV in Europe as defined by the SHE faculty and summarizes the findings of the group in terms of data gaps. The remaining articles within this supplement review current data on the five SHE topics.

Remarques concernant les métaphores de Freud à propos du « miroir » et du « récepteur »
Authors: Balint Enid , Dupont Judith
Published: June 2013

L’auteur revient au conseil donné par Freud aux analystes, en 1912, à savoir se conduire avec le patient comme un miroir réfléchissant. Elle en montre les limites, mais aussi l’intérêt dans certaines situations, ou à certains moments d’une analyse, avec exemples cliniques à l’appui. L’article ne manque pas non plus d’un certain intérêt historique : écrit par l’épouse du représentant littéraire de Sándor Ferenczi, il arrive au moment où l’œuvre de ce dernier devient audible et qu’on passe résolument d’une psychologie à une personne à une psychologie à deux personnes.

Le dialogue intérieur, avec Les yeux de l'âme de Jean-Claude Rolland
Authors: Dollé-Monglond Brigitte
Published: June 2013

Dans la continuité de ses précédents ouvrages, J.-C. Rolland nous invite à l’exploration du travail analytique, à partir de la lecture de Freud, de l’écoute des patients, et de ces tissages souterrains entre différentes disciplines qui regardent avec les yeux de l’âme. Sont esquissées ainsi des analogies entre l’expérience de la cure et le tragique de l’acte du poète et du peintre. Mon propos est de souligner certaines voies centrales de résonances : les rapports de l’image et du langage, la spécificité du concept d’état borderline, la singularité du complexe du renoncement.
Mathématiques et Naturphilosophie : L'exemple de la controverse entre Johann Jakob Wagner et Johann Schön (1803-1804)
Authors: Morel Thomas
Published: June 2013

Johann Jakob Wagner (1775-1841), disciple de Schelling et important acteur de la Naturphilosophie allemande, publie en 1803 un ouvrage intitulé Von der Natur der Dinge ( De la nature des choses ) où il lance le projet d’une réforme de la mathématique visant à l’intégrer à la philosophie. Il provoque ainsi un débat animé dans lequel divers acteurs, scientifiques et philosophes, vont exprimer leur point de vue sur la relation entre les deux disciplines. Nous nous intéresserons en particulier à la réponse de Johann Schön (1771-1839), un mathématicien qui publie l’année suivante un livre aujourd’hui oublié dans lequel il rejette vigoureusement le projet de Wagner. L’analyse de ce débat aide, dans le contexte des réformes universitaires du début du xix e , à comprendre l’histoire de l’émergence en Allemagne d’une discipline mathématique autonome, ainsi que l’apparition de nouvelles problématiques autour de l’axiomatisation et de la systématique.
Proles sine matre creata: el anhelo prometeico en la historia del cuerpo humano en Occidente
Authors: Montiel Luis
Published: June 2013

Desde los inicios de la modernidad puede detectarse en el pensamiento occidental una tendencia a pensar el cuerpo humano como susceptible de manipulación técnica, hasta el extremo de concebir la posibilidad de fabricarlo. Las figuras del homúnculo y el autómata, herederas de la del gólem, representan las cristalizaciones más evidentes de esta pretensión. El presente trabajo pretende explorar la psicología que está en la base de este designio a partir de la teoría psicológica de C.G. Jung desarrollada más recientemente por J. Hillman, sobre la hipótesis de que dicho proyecto implica la negación de lo femenino y, con ello, de los aspectos más propiamente psíquicos de lo humano, al servicio de una cosmovisión unilateralmente racionalista y materialista. El referente mítico –psicológico, en la perspectiva de los autores mencionados- capaz de suministrar las claves profundas de ese proyecto sería Prometeo.

Dentro del marco de su teoría de la visión, y con la ayuda de múltiples observaciones empíricas de la naturaleza, intentó fundamentar las razones por las que las agudezas visuales difieren de unos sujetos a otros, así como la presencia de ciertas ametropías, discerniendo entre la miopía y la presbicia. Para Aristóteles la miopía, falta de agudeza de visión lejana, es debida a una proporción inadecuada de humedad en el ojo o a una morfología ocular anómala.
La concepción del espacio-tiempo en la cosmología sarvāstivāda
Authors: Arnau Juan
Published: June 2013

El presente artículo se orienta a la reconstrucción de los modelos cosmológicos de la escuela de Cachemira (s. IV), registrados en el compendio de la escuela sarvāstivāda-vaibhāsika titulado Abhidharmakośabhāsya, atribuido al monje budista Vasubandhu. Se identifican algunas de las fuentes textuales que dieron lugar a estos modelos y se describe con detalle su estructura general, compuesta de tres ámbitos (sensible, materia sutil e inmaterial). Se analizan algunas de las características más relevantes del espacio y del tiempo y su relación con la vida consciente, descubriéndonos unos modelos cosmológicos inéditos entre sus contemporáneas grecolatinos.
Historia de las emociones: una corriente historiográfica en expansión
Authors: Zaragoza Bernal Juan Manuel
Published: June 2013

Peter Burke, en su obra publicada en 2005 Is There a Cultural History of the Emotions?, se preguntaba si existía una historia cultural de las emociones. La pregunta resulta cuanto menos extraña teniendo en cuenta que dicho texto se catalogaba explícitamente como “historia de las emociones”. Las editoras del libro –una, historiadora de la medicina, la otra, del arte–, tomaban como punto de partida del mismo, precisamente, la historicidad de las emociones, no sólo de sus concepciones y representaciones, sino de las emociones mismas.

We describe a rare case of deep vein thrombosis (DVT) in children, highlight the importance of early diagnosis of rare disease with potential complications. In a 5 year old boy presented with persistent leg pain without any obvious cause. Detailed investigation led to diagnosis of DVT. As there are common differential diagnoses for leg pain in children, pediatricians usually have a low index of suspicious of DVT in children. This case highlight that paediatricians must consider DVT in their differential diagnosis when children present with leg pain.

Sammulfar (arsenic trioxide) is a notorious poison and has extensively been studied for its toxicity. It is in use for various purposes for centuries and is used even today as a therapeutic agent in the form of kushta (calx) in traditional systems of medicine, particularly Unani medicine, but without apparent safety data. The present study, therefore, was conducted to produce data for prolong use of calx of arsenic trioxide. The calx (test drug) was prepared by the method described in National Formulary of Unani Medicine. The study was carried in healthy Wistar rats of either sex; weighing 150-250 g; 2-3 months of age, in a dose dependent manner, following the methods of Gupta et al. (2002), Ghosh (2008) and Klaassan (2008). The animals were divided into four groups of 10 animals each. Group I served as control, where as group II, III and IV were used for three dose levels of the test drug i.e. low (8.75 mg–1 kg), medium (17.50 mg–1 kg) and higher (26.25 mg–1 kg). Standard parameters usually applied for chronic toxicity studies were considered. The study revealed dose dependent toxicity. Usual signs of chronic toxicity were observed during the study. Low dose of Kushta Sammulfar (KSF) did not produce remarkable toxic effects. Mild to moderate toxicity was seen in KSF-II and KSF-III.
Mission, identity and ethics in Mark: Jesus, the patron for outsiders
Authors: Van Eck Ernest
Published: June 2013

In this contribution the relationship between mission, identity and ethics in Mark was investigated by means of a postcolonial and social-scientific reading, with a focus on patronage as a practice that constituted the main bond of human society in the 1st-century Mediterranean world. Mark’s narrative world is a world of three kingdoms (the kingdoms of Rome, the Temple elite and God). Each of these kingdoms has its own gospel, claims the favour of God or the gods, has its own patron, and all three have a mission with a concomitant ethics. Two of these gospels create a world of outsiders (that of Rome and the Temple), and one a world of insiders (the kingdom of God proclaimed and enacted by the Markan Jesus). According to Mark, the kingdom of God is the only kingdom where peace and justice are abundantly available to all, because its patron, Jesus, is the true Son of God, and not Caesar. Being part of this kingdom entails standing up for justice and showing compassion towards outsiders created by the ‘gospels’ of Rome and the Temple elite.
Verskuiwende denke van die 2012-GKSA-Sinode
Authors: Van Helden Sophia
Published: June 2013

In hierdie artikel word die moontlikheid van ’n denkverskuiwing bespreek en gemeet aan die hand van navorsing wat gedoen is onder die afgevaardigdes van die 2012-GKSA-Sinode. Die agtergrond rondom denkverandering word bespreek, waarna die bevindings van die empiriese studie oor die stand van denke aan die hand van drie aktuele stellings aangetoon word. Die stellings spruit voort uit die verskynsel van dalende lidmaatgetalle binne gemeentes. Navorsing wat tydens die Sinode aan die hand van ’n vraelys plaasgevind het, het gefokus op die mate van bewussyn by die afgevaardigdes in verband met die krisissituasie wat gereformeerde gemeentes ervaar ten opsigte van dalende lidmaatgetalle. Daarna is die moontlikheid van verskuiwende denke terug na die eise van die Groot Opdrag ondersoek. Indien verskuiwende denke wel voorkom, is ten slotte nagegaan of die totale Suid-Afrikaanse bevolking, ongeag taal of kultuur, as teikengroep gereken kan word. Die kwantitatiewe en kwalitatiewe benadering verskaf insiggewende statistiek, asook insae in verband met die denkverskuiwing en die sleutelposisie van die Groot Opdrag in die verskynsel van dalende lidmaatgetalle in gemeentes.This article discusses the possibility of shifting thought and measuring it on the basis of research conducted among the 2012 RCSA Synod delegates. Background regarding the change in thought is discussed and followed up by the findings of an emperical study about the state of thinking, using three relevant statements. These statements stem from the phenomenon of declining numbers in congregations. The research is conducted at the Synod by means of a questionnaire, focused on the degree of awareness among the delegates regarding the declining numbers of members as a crisis situation in the reformed churches. Thereafter the possibility of a turnaround in thinking towards the demands of the Great Commission was addressed. The last statement focused on whether the entire South African population, regardless of language and culture, would be regarded as the target group in case a changing in thought exists. The qualitative and quantitative approach provide informative statistics, as well as insight regarding the shifting in thought and the key position the Great Commission takes in the phenomenon of declining numbers of members in congregations.
The impact of work experience of small and medium-sized enterprises owners or managers on their competitive intelligence awareness and practices
Authors: Pellissier Rene , Nenzhelele Tshilidzi E.
Published: June 2013

Background: Information technology has assisted in globalisation, which then assisted in making international trade easier. Consequently, businesses no longer compete with local competitors only but also with international ones, leading to intense competition in all business sectors. Businesses will hardly practice what they are not aware of and therefore needs to know about their competitive landscape. Competitive intelligence (CI) gathers information from both the internal and external business environments, and analyses these for use by decision makers. Whilst awareness of the importance of CI is wide, it is not practiced optimally, making the need for creating awareness of the benefits of CI important.Objectives: The objective of this research was to establish the influence of owners’ and managers' working experience of CI practice and awareness in the small and medium-sized enterprises (SMEs) environment.Method: This research was quantitative in nature and a questionnaire was used to collect data from SMEs owners and managers in The City of Tshwane Metropolitan Municipality.Results: This research indicates that SMEs in the study are aware of CI through education and training. Moreover, the study reveals that the working experience of owners and managers has a great influence on awareness and practice of CI and one should implement training programmes in this domain to assist with building competitive advantage.Conclusion: Small and medium-sized enterprises owners or managers’ years of working experience has a greater influence on awareness and practice of CI. Put differently, years of working experience is a great predictor of CI awareness and practice.
Infecciones Oportunistas en Trauma

El trauma constituye la primera causa de muerte para el grupo etario entre 1 y 45 años de edad. La principal causa de muerte es el traumatismo de cráneo, seguido por la hemorragia. La infección es responsable globalmente del 10% de las causas de muerte, pero es la causa del 54% de las muertes luego de las primeras 48 horas y del 76% luego de la primera semana.

El cuerpo humano responde a la agresión mediante un sindrome de respuesta inflamatoria (SIRS), seguido por el CARS (compensatory antiinflamatory response syndrome) con franca disminución de la respuesta inflamatoria mientras que en otros predomina el MARS (mixed anti and inflamatory response syndrome) cuando la respuesta es equilibrada. Recientemente, se ha jerarquizado la importancia de las células T en la respuesta a la infección.

El paciente traumatizado puede desarrollar infecciones relacionadas con el trauma en sí mismo (lesiones de partes blandas, fracturas expuestas, traumatismo de vísceras huecas, infecciones asociadas a la colocación de tubos de drenaje pleural) o infecciones del paciente crítico (neumonía asociada al ventilador, bacteremias asociadas a catéteres o infecciones urinarias). Es muy importante conocer la flora autóctona microbiológica de la UCI para comenzar los tratamientos empíricos hasta la detección del microorganismo causante de la infección.

De define como oportunista a todo microorganismo que presenta capacidad para multiplicarse y producir enfermedad si el paciente presenta alteraciones en sus mecanismos de defensa. La presencia de respuesta inflamatoria en trauma y de alteraciones de la inmunidad lo pueden exponer a infecciones asociadas a Candida, a Clostridium Difficile, a Citomegalovirus y a Herpes simple que deben siempre tenerse en cuenta en el diagnóstico diferencial.

Asimismo se debe contar en la institución con un programa de control de infecciones, un programa de control de antibióticos y de bundles para la adecuada vigilancia infectológica y de prevención de infecciones.
