Jangwa Pana, el Caribe y “Publish or Perish”
Authors: Martínez-Dueñas William Andrés , Arias-Ocampo Angélica María
Published: June 2017

La reconfiguración de la revista Jangwa Pana ha permitido que su propósito original aún se mantenga: ofrecer un espacio para crear aquello que muchos llaman caribe y que los que tengan algo que decir, lo puedan decir, siempre y cuando se sometan al proceso editorial. Desde la lógica del “publish or perish”, la revista posee una dinámica de citación que hace que mantengamos el compromiso de seguirla editando, tratando de hacernos un espacio en la lógica de las políticas transnacionales de la publicación científica que hemos asumido sin cuestionamiento alguno. Finalmente, y quizá lo más importante, es que podemos decir que Jangwa Pana es una revista que se consolida como una publicación centrada en temas inter y transdisciplinarios con enfoque crítico desde las diferentes disciplinas de las Ciencias Sociales y las Humanidades.
Estructura, cultura y cambio organizacional. Cultura – cambio – forma – fuerza
Authors: Alvarez Alexandra Tatiana Valle , Córdova Telmo Diego Proaño , Lascano Mary Elizabeth Cruz
Published: June 2017

La teoría de las organizaciones desde el paradigma mecanicista ha puesto especial atención en temas de estrategia y estructura además del carácter contingente de estas estructuras con respecto a su entorno, en este espacio se ha hecho necesario un enfoque desde la cultura y estructura organizacional hacia la gestión del cambio con miras a lograr la eficiencia en las organizaciones. El objetivo de este trabajo es explorar en la organización a partir de las fuentes bibliográficas, los niveles culturales identificados a través de los supuestos subyacentes, valores adaptativos y artefactos, así como las dimensiones culturas que pueden revelarse como dominantes. Se pretende hacer un breve recorrido sobre los fundamentos teóricos de la estructura de las organizaciones con énfasis en los mecanismos coordinadores propuestos por Mintzberg; que caracterizan a las configuraciones estructurales típicas, identificadas como estructura simple, burocracia mecánica y profesional, forma divisional y adhocracia. En torno a este abordaje, los procesos de cambio que buscan diferenciación competitiva, reconocen al cambio en la estructura y en la cultura como factores que podrían influenciar en el diseño de una configuración particular en las organizaciones y lograr un impacto satisfactorio en su desempeño, así, de manera complementaria son justamente los diseños estructurales mecanicistas y la cultura dominante, los que podrían revelarse como impedimentos poderosos para el cambio.

O Tour da Experiência caminhos do Brasil imperial em Vassouras (RJ) Qual experiência está sendo promovida pelo Estado?
Authors: Gomes Pãmela Ketulin Mattos , Mendonça Teresa Cristina De Miranda
Published: June 2017

Este artigo busca identificar o papel da política pública do turismo no Brasil, tendo como objeto de análise o Programa Tour da Experiência na região turística Vale do Café, em especial no município de Vassouras (RJ), pretende apresentar qual experiência histórica está sendo promovida, chancelada e intermediada por uma ação de política pública. Os materiais e métodos utilizados nesse trabalho se constituíram de abordagem qualitativa, utilizando um estudo do tipo exploratório e descritivo, além de pesquisa bibliográfica e documental. O Tour da Experiência é um programa do Ministério do Turismo em parceria com SEBRAE e Instituto Marca Brasil de abrangência nacional desenvolvido desde 2006, certifica empreendimentos que oferecem ao visitante mais do que a observação contemplativa, oferecem vivencia, participação, emoções, ambientação contextualizada, atividade lúdicas, entre outras formas de experimentar. Considerando que hoje o Vale do Café não produz mais café, as possíveis experiências se baseiam nos simbolismos deste Vale, a partir de história e memória social de uma época de larga produção cafeeira. Possivelmente representados pelos cenários das fazendas, pelos atores escravos, sinhás, barões e baronesas, na gastronomia, nas danças, jogos e músicas, entre outros desenvolvidos pelos empreendimentos turísticos como elementos de vivência e interpretação de um momento histórico. Contudo foi identificado que os produtos dos empreendimentos certificados pela referida ação pública estão desarticulados de história e memória social e ainda dos critérios para formalizar a certificação, como criação de produtos inovadores, valorização de saberes locais e relação com história do Brasil Imperial.

The Rule of Histology in the Diagnosis of Periprosthetic Infection: Specific Granulocyte Counting Methods and New Immunohistologic Staining Techniques may Increase the Diagnostic Value
Authors: Boettner Friedrich , Koehler Gabriele , Wegner Alexander , Schmidt-Braekling Tom , Gosheger Georg , Goetze Christian
Published: June 2017

Objective:

The current study investigates the diagnostic accuracy of the criteria described for frozen sections and whether modern leukocyte specific staining techniques including leukocyte peroxidase and Naphtol-AS-D-chloroacetate-esterase will improve the accuracy of the intra-operative histology.

Method:

77 patients undergoing revision total hip and knee arthroplasty were included in this retrospective study. Patients were grouped into septic and aseptic based on intraoperative cultures. Tissue samples were analyzed utilizing the Mirra, Feldman, Lonner, Banit and Athanasou criteria.

Results:

An experienced pathologist had a high specificity (96%), but rather low sensitivity (57%) diagnosing infection. By using the Banit-, Mirra-, or Athanasou-criteria the sensitivity is increased to 0.90. The Feldman- and Lonner-criteria have a lower sensitivity (0.48 and 0.38), however, an increased specificity of 0.96 and 0.98, respectively. The Banit cut off has the highest accuracy (86%). MPOX and NACE staining increased the sensitivity and accuracy up to 100% and 92% respectively.

Conclusion:

Banit’s cut off is the most accurate histologic criteria to diagnose infection. Modern leukocyte specific staining techniques slightly improve the accuracy. The synovial fluid white blood cell count appears to be the most accurate intraoperative test.

Authors: Wasilczuk Jarosław , Sobiech Marian
Published: June 2017

W referacie przedstawiono wyniki analiz cieplnych oraz warianty modernizacji systemu ogrzewania w istnie- jącym (jednorodzinnym, wolnostojącym, niepodpiwniczonym, z poddaszem użytkowym) budynku mieszkalnym, zbudowanym na przełomie lat 80. i 90. ubiegłego wieku, w celu przystosowania go do aktualnych wymagań w zakre- sie izolacyjności cieplnej oraz racjonalizacji zużycia ciepła. Analizowano istniejący budynek mieszkalny, jednorodzin- ny, wolnostojący, niepodpiwniczony, z poddaszem użytkowym, który jest zlokalizowany w powiecie legionowskim w woj. mazowieckim. Ściany zewnętrzne budynku, o powierzchni użytkowej 140,87 m2 i całkowitej 206,16 m2, są wy- konane z bloczków gazobetonowych na zaprawie klejowej o całkowitej grubości 36,5 cm. Strop jest wykonany z prefa- brykatów gęstożelbetowych Teriva – 1. Dach jest symetryczny, dwuspadowy, krokwiowo-jętkowy – pokryty blachoda- chówką. W celu wybrania optymalnego zakresu termomodernizacji istniejącego budynku wykonano obliczenia cieplne dla 3 różnych wariantów, a mianowicie: wariant 1 – ocieplenie ścian zewnętrznych uniwersalnym materiałem termo- izolacyjnym swisspor LAMBDA fasada, produkowanym metodą spieczenia polistyrenu o λ=0,033[W/mK] i grubości płyt 10 cm; wariant 2 – wymiana stolarki okiennej na nową o podwyższonej jakości; wariant 3 – połączenie wariantów 1 i 2 oraz dodatkowo ocieplenie połaci dachowej i podłogi. Na podstawie obliczeń współczynnika przenikania ciepła i analizy finansowej wybrano wariant 3, co pozwoliło zmniejszyć wskaźnik sezonowego zapotrzebowania na energię pierwotną z EP=251,02 kWh/rok.m2 do wartości 150,59 kWh/rok.m2. Przebudowano instalację centralnego ogrzewania i ciepłej wody, analizowano 3 warianty: wariant 1 – instalacja c.o. z grzejnikami stalowymi panelowymi, podłączona do kotła gazowego; wariant 2 – instalacja c.o. z grzejnikami stalowymi panelowymi w pokojach i z ogrzewaniem podło- gowym w łazienkach, podłączona do kotła gazowego; wariant 3 – instalacja c.o. z grzejnikami stalowymi panelowymi w pokojach i z ogrzewaniem podłogowym w łazienkach, podłączona do kotła gazowego ze wspomaganiem kolekto- rów słonecznych. Ostatecznie wybrano również wariant 3, co pozwoli na zmniejszenie zużycia gazu i efektywniejsze wykorzystanie energii słońca.
Predicting Punitive Attitudes: Racial-Animus towards New Immigrant and Aboriginal Minority Groups as a Mediating Agent upon Public Crime Concerns
Authors: Brookman Ruth P. , Wiener Karl K. K.
Published: June 2017

In English-speaking Western society’s punitive attitudes towards the sentencing of criminal offenders is a well-established phenomenon. Two theoretical models; the Crime-distrust model and Racial-animus model are demonstrated predictors of punitive attitudes. However, little is known about how racial prejudice impacts the association between the public’s crime concerns and their demand for harsher sentencing outcomes. The present study utilises online survey data obtained from a convenience sample of 566 Australian residents to examine the Racial-animus model as a mediating agent upon the Crime-distrust model and its relationship with punitive attitudes. A significant indirect effect of racial animus is demonstrated upon the perception of increasing crime rates and public confidence in the court system and punitive attitudes, regardless of whether animus is towards new-immigrants or Indigenous Australians. A significant indirect relationship between fear of crime and the demand for harsher sentencing is only demonstrated through negative perceptions of new immigrants. Results lend support for a mediation model whereby the indirect effect of fear of crime is significant when mediated by negative sentiment towards new-immigrants but not towards Indigenous Australians. Future research using a representative sample of the Australian population is indicated to increase the confidence with which findings are interpreted.
How social media strategies of nonprofit organizations affect consumer donation intention and word-of-mouth
Authors: Feng Yi , Du Lanying , Ling Qian
Published: June 2017

Our purpose in this study was to validate the role of consumers' perceived trust and satisfaction in the internal mechanism of the effect of nonprofit organizations' social media strategies on consumers' donation intention and electronic word-of-mouth. We developed an online survey
that was completed by 242 followers of the One Foundation nonprofit organization on social media. Responses were analyzed with a structural equation model. The results showed that both dissemination and interactivity had a significantly positive effect on consumers' perceived trust and satisfaction,
which subsequently influenced their donation intention, and electronic word-of-mouth. Disclosure had a positive effect only on trust. Practical implications for managers of nonprofit organizations are discussed.

Authors: Mączyńska Joanna , Kupczyk Adam , Sikora Michał , Tucki Karol , Żelaziński Tomasz
Published: June 2017

W opracowaniu przedstawiono stan obecny oraz przyszłość sektorów biopaliw transportowych w Polsce. Ze względu na istotne znaczenie, jakie w tej roli odgrywają uwa­runkowania prawne, omówiono najważniejsze dyrektywy i ustawy wpływające na kształt omawianych sektorów. Metodą punktową, wielokryterialną M.E. Portera określono atrakcyjność krajowych sektorów biopaliw transportowych, tj. biodiesla i bioetanolu z surowców jadalnych (tzw. biopaliw 1. generacji) oraz bioetanolu z surowców niejadalnych – przede wszystkim lignocelulozy (biopaliwo 2. generacji). Wiele czynników występujących w makro- i mikrootoczeniu sektorów biopaliw 1. generacji powoduje, że ich atrakcyjność systematycznie maleje. Natomiast sektor bioetanolu 2. generacji, którego obecnie produkcja w Polsce nie występuje w skali przemysłowej, charakteryzuje się stosunkowo wysoką i rosnącą atrakcyjnością.

Spatio-temporal image inpainting for video applications
Authors: Voronin Viacheslav , Marchuk Vladimir , Makov Sergey , Mladenovic Vladimir , Cen Yigang
Published: June 2017

Video inpainting or completion is a vital video improvement technique used to repair or edit digital videos. This paper describes a framework for temporally consistent video completion. The proposed method allows to remove dynamic objects or restore missing or tainted regions presented in a video sequence by utilizing spatial and temporal information from neighboring scenes. Masking algorithm is used for detection of scratches or damaged portions in video frames. The algorithm iteratively performs the following operations: achieve frame; update the scene model; update positions of moving objects; replace parts of the frame occupied by the objects marked for remove by using a background model. In this paper, we extend an image inpainting algorithm based texture and structure reconstruction by incorporating an improved strategy for video. Our algorithm is able to deal with a variety of challenging situations which naturally arise in video inpainting, such as the correct reconstruction of dynamic textures, multiple moving objects and moving background. Experimental comparisons to state-of-the-art video completion methods demonstrate the effectiveness of the proposed approach. It is shown that the proposed spatio-temporal image inpainting method allows restoring a missing blocks and removing a text from the scenes on videos.

Mucometra in a bitch as a consequence of a serious professional mistake
Authors: Djuric Miloje , Jovanovic Ljubomir , Anicic Milan , Nedic Svetlana , Nedic Sreten
Published: June 2017

An apathetic 14-year-old Hungarian Puli bitch was presented with a seven day history of vaginal discharge and reported ovariohysterectomy (OHE) conducted six years ago. Clinical examination showed elevated body temperature (39.5?C), enlarged abdomen, and vulvar swelling. Despite a reported OHE in the anamnesis, ultrasound examination of the abdomen demonstrated the presence of both ovaries and a large anechogenic zone resembling the uterus. Vaginal cytologic examination and hormonal analysis indicated that the bitch was in the oestrus phase of the cycle. After laparotomy, both intact ovaries and an enlarged uterus with marked adhesions and filled with liquid content were visualised. The cervix was situated in the caudal part of the abdominal cavity and connected to the uterus by only an adhesion stump. After extirpation, uterus and ovarian tissue samples were sent for histological examination. Histological findings of uterus and ovarian tissue samples indicated a diagnosis of mucometra. Obviously, OHE was not conducted professionally, and the procedure performed only prevented conception, but ovaries and uterus continued to be active and caused a serious health disorder after six years. When only a part of the ovaries or uterus is left after OHE, health complications can appear up to ten years later. Our case testifies that even if both ovaries and the entire uterus are left after OHE without communication with cervix and vagina, a bitch can live without noticeable health disorders up to six years. This underlines the importance of lymphatic drainage and resorption processes in the uterus as well as evacuation of uterus content through the vagina.
La modernización administrativa del gobierno de Felipe Calderón: entre la austeridad y la reforma.
Authors: Pardo María Del Carmen
Published: June 2017

Se observa el proceso de modernización administrativa del gobierno de Felipe Calderón a la luz de su entorno político, y se lo intenta comparar con las acciones que se llevaron a cabo en el gobierno de Vicente Fox. Se analizan asimismo las estrategias que se pusieron en marcha y los resultados que se ofrecieron. La premisa es que los factores contextuales políticos y económicos, cuando el gobierno llega al poder y durante su administración, condicionaron los alcances de la modernización administrativa y limitaron su utilidad. Mientras que hubo cambios aislados, no se estableció un proceso de reforma integral para fortalecer a la Administración Pública, al menos a nivel federal.
Rebellious Christs the King, virgins and believers in the Mexican highlands (1765-1770)
Authors: Béligand Nadine
Published: June 2017

In the years 1765-1770 a series of rebellions broke out in territories on the margins of the Kingdom of New Spain. The underlying causes were both religious –ordaining indigenous priests to direct religious practices– and political –aversion to the Spanish populationin nature. The leaders of those movements appropriated collective yearnings for vengeance that they coupled with a fervent belief in the coming of a new world; one in which the Indians would no longer be the van- quished but victorious, for God himself would descend to Earth to impose Divine Justice to their benefit. The central figures in those movements reflect reciprocal influences between autochthonous tradition (eg. shamanism, ingesting psychotropic plants, hallucinations, cults formed around magical individuals), and Christian theology (mass, administration of sacraments, belief in one true God, adoption of the names Christ and Juan Diego). The visionaries, those most intimate figures of subversion, behaved as mirrors of indigenous Christianity, but their mystical adventure reveals as well a collective identity in which cultural difference existed halfway between imitations of sanctity and the indigenization of Catholic practice. Hence, indigenous Christianity, as it was practiced in frontier territories, underwent a whole set of structural transformations the result of which was their confiscation in order to obtain political and religious autonomy.
IMPUESTO A LA CARNE: MEMORIA DEL DESASTRE
Authors: Rodrigo-Mendizábal Iván Fernando
Published: June 2017

This article analyzes the narrative dimensions of Diamela Eltit’s Impuesto a la carne. Written as the memory of a failed nation in Chile, product of the authoritarianism that characterized its history since its emancipation, the novel derives into dystopian tale that denounces how political power made it the reason for its establishment. This bad calved nation has captured and with it is still experiencing; however, this nation in ruins still screams from it inside detention. Eltit, with this novel, faces the neoliberal imaginary that made us forget the social conquests, especially of the Chilean women.
Queer Provisionality: Mapping the Generative Failures of the Transborder Immigrant Tool
Authors: Reed Alison
Published: June 2017

Alison Reed investigates the border- and boundary-crossing performance of Electronic Disturbance Theater 2.0’sTransBorder Immigrant Tool (TBT), an incomplete cell phone program that offers GPS, guidance, and poetry to those attempting to cross into the United States across the Mexico/US border. Reed suggests a provocation-based performance of “queer provisionality,” revealing the aesthetics of oppressive power structures by juxtaposing them to social utopias. Interrogating the national neoliberal project of both US liberalism and US conservatism, Reed’s essay is also a transcription of the performances launched around TBT, the social and political machinery set into motion by Electronic Disturbance Theater’s failed utopian project.
From ‘Hip Hop Revolutionaries’ to ‘Terrorist-Thugs’: ‘Blackwashing’ between the Arab Spring and the War on Terror
Authors: El Zein Rayya
Published: June 2017

Rayya El Zein takes up a global analysis of how ideas of blackness, whiteness, and Arabness circulate in post-9/11 media accounts and argues that these concepts work to mediate Western understanding of politics in the Arab world. El Zein unpacks the paradox by which blackwashing is differentially deployed to mark certain Arab subjects as a “good rapper” or a “bad rapper,” and how both of these valences serve to expand neoliberal orientalism through the political familiarity promised by blackness. As an alternative, El Zein suggests attention to the material, historical, and geographic specificities of the power struggles that structure racial capitalism, classism, and racism, especially and essential because of their potential international unrecognizability.
Livelihood Patterns of Majhi and Kumal Communities in the Arun Valley, Eastern Nepal
Authors: Rai Dhyanendra Bahadur
Published: June 2017

The present paper is an attempt to portray the livelihood patterns of two marginalized communities such as Majhi and Kumal of Kumaltar village in the Arun valley, eastern Nepal. Data were collected from all 28 households of both communities. The findings show that agriculture and livestock now are the main occupations for their living. Prior to these, ferrying, fishing and pottering were their traditional occupations when they moved to Kumaltar in several years ago. As the production from agriculture and livestock is inadequate, other activities such as mobile trading of merchandise goods and local goods, pig and poultry farming, bamboo and ropes making, and local grains based country alcohol making have been adopted by them as alternative strategies for sustaining their livelihood. In addition, recently, the youths of these communities have migrated to different parts within the country, as well as in foreign countries for employment for better living in the village.The Geographical Journal of Nepal, Vol. 7, 2009: 7-14
Evolution of Medical Geography: An Overview
Authors: Nepal Pashupati
Published: June 2017

Health is not merely absence of disease or informity, it is a state of complete physical, mental and social well-being. Infact, health is dynamic equilibrium between man and his environment. A commission on medical geography was made by international Geographical Union (IGU) and its report was discussed at IGU congress in Washington in 1952. Since then the analysis of health and disease through man-environment relationships has attracted the attention of geographers to work in medical geography. In this context, present article seeks to analyse the development, purpose and field of medical geography. It also attempts to analyse environmental control of disease and susceptibility and prospects of medical geography in Nepal. Finally, it concludes that geographers can make major contributions to help reduce suffering of human health and increasing longevity if they are able to establish causal links between specific disease and environment.The Geographical Journal of Nepal, Vol. 7, 2009: 33-40
GIS Mapping Analysis of Energy Consumption Patterns in Nepal
Authors: Sharma Puspa
Published: June 2017

This paper is an attempt to use computerized GIS tool to visual portray of consumption of the main energy sources – firewood, electricity, kerosene and LPG at district level for the whole country into four levels. A series of tables have also been constructed to depict the average levels of consumption of those energy sources at regional levels. The consumption patterns are that the firewood consumption has dominated over all the energy sources, followed by kerosene, electricity and LPG. The firewood energy source is the largest and available throughout the country. This can be explained by the extensive forest coverage across the country, which is largest in the mountain districts. The consumption patterns of electricity and LPG are more or less the same for the ecological regions; with highest in the Tarai, while the mountain being the lowest. The country has huge water reserviour for generating hydro electricity, but its consumption shares nearly two and half less of the firewood, or half of the kerosene. The other two energy sources - kerosene and LPG are to be imported.Due to lack of time series data on household level energy consumptions, HDI has been taken to predict the energy consumptions in the future. It shows that the household proportion in consuming firewood will be decreased, signifying lessening burden on forest resource. On the other hand, the household consumption of hydro electricity will be increased, which will mean to increasing utilization of locally available water sources and reducing a huge amount of transportation cost incurred for distribution of kerosene and LPG particularly in the remote hill and mountain districts. But however, increasing projected consumption of LPG would require foreign currencies in the future.The Geographical Journal of Nepal, Vol. 7, 2009: 41-52

Published: June 2017

OBJECTIVE

The precise threshold differentiating normal and elevated intracranial pressure (ICP) is variable among individuals. In the context of several pathophysiological conditions, elevated ICP leads to abnormalities in global cerebral functioning and impacts the function of cranial nerves (CNs), either or both of which may contribute to ocular dysmotility. The purpose of this study was to assess the impact of elevated ICP on eye-tracking performed while patients were watching a short film clip.

METHODS

Awake patients requiring placement of an ICP monitor for clinical purposes underwent eye tracking while watching a 220-second continuously playing video moving around the perimeter of a viewing monitor. Pupil position was recorded at 500 Hz and metrics associated with each eye individually and both eyes together were calculated. Linear regression with generalized estimating equations was performed to test the association of eye-tracking metrics with changes in ICP.

RESULTS

Eye tracking was performed at ICP levels ranging from −3 to 30 mm Hg in 23 patients (12 women, 11 men, mean age 46.8 years) on 55 separate occasions. Eye-tracking measures correlating with CN function linearly decreased with increasing ICP (p < 0.001). Measures for CN VI were most prominently affected. The area under the curve (AUC) for eye-tracking metrics to discriminate between ICP < 12 and ≥ 12 mm Hg was 0.798. To discriminate an ICP < 15 from ≥ 15 mm Hg the AUC was 0.833, and to discriminate ICP < 20 from ≥ 20 mm Hg the AUC was 0.889.

CONCLUSIONS

Increasingly elevated ICP was associated with increasingly abnormal eye tracking detected while patients were watching a short film clip. These results suggest that eye tracking may be used as a noninvasive, automatable means to quantitate the physiological impact of elevated ICP, which has clinical application for assessment of shunt malfunction, pseudotumor cerebri, concussion, and prevention of second-impact syndrome.
Modified dorsal root entry zone lesioning for intractable pain relief in patients with root avulsion injury
Authors: Takai Keisuke , Taniguchi Makoto
Published: June 2017

OBJECTIVE

Dorsal root entry zone (DREZ) lesioning has been the most effective surgical treatment for the relief of intractable pain due to root avulsion injury, but residual pain and a decrease in pain relief in the follow-up period have been reported in 23%–70% of patients. Based on pain topography in the most recent studies on neuropathic pain, the authors modified the conventional DREZ lesioning procedure to improve clinical outcomes. The presumed rationale for this procedure is to eliminate the spontaneous discharges of neurons in the superficial spinal dorsal horn as well as wide dynamic range neurons in the deep spinal dorsal horn.

METHODS

Ten patients with avulsion-related pain underwent surgery between 2011 and 2015. The surgical procedure was described and postoperative pain relief was assessed as follows: excellent (residual pain never exceeded 3 on the visual analog scale [VAS] without medication), good (residual pain never exceeded 5 on the VAS with medication), and poor (residual pain was greater than 5 with medication). Specific perioperative complications were assessed.

RESULTS

The aim of this surgical procedure was to destroy the deeper layers of the posterior horn of spinal gray matter, which was in contrast to the procedures of Nashold and Sindou, which were to destroy the superficial layers. All patients achieved excellent (n = 7, pain relief without medication) or good (n = 3, pain relief with medication) pain relief postoperatively, and the recurrence of pain was not reported in any patients (median 29 months after surgery, range 12–64 months). Nine patients (90%) achieved complete pain relief (a score of 0 or 1 on the VAS) with or without medication. No surgical site complications such as infection or CSF leakage were noted. No motor deficit was observed in any patient. A sensory deficit was observed in 2 patients and disappeared within 1 month in 1 patient. New pain at the adjacent level of DREZ lesioning was observed in 3 patients and disappeared within 1 month in 2 patients. In the other patient, new pain persisted and required analgesics.

CONCLUSIONS

These preliminary results demonstrated that total and persistent global pain relief was achieved with the modified DREZ lesioning procedure in 90% of patients without major neurological deficits. The clinical improvements achieved by this modified surgical procedure support the hypothesis that not only the superficial layers, but also deeper layers of the spinal dorsal horn are associated with intractable pain due to root avulsion injury.
Coronary atheroma [14 cm] extracted from the right coronary artery during off-pump coronary artery bypass grafting
Authors: Ranjan Redoy , Adhikary Dipannita , Saha Heemel , Saha Sanjoy Kumar , Hasan Kamrul , Adhikary Asit Baran
Published: June 2017

Coronary endarterectomy is a good option for surgical revascularization in diffusely coronary artery disease. In coronary artery bypass surgery, a diffusely diseased right coronary artery is an obstruction to accomplishing complete myocardial revascularization, subsequently increasing the likelihood of a poor postoperative prognosis. Here, we report a case of extraction of a long segment coronary atheroma (14 cm) from right coronary artery during off-pump coronary artery bypass grafting using closed endarterectomy technique followed by reconstruction with saphenous venous graft.
Memories of the Unlived Body: Jean-Louis Schefer, Georges Bataille and Gilles Deleuze
Authors: ffrench Patrick
Published: June 2017

Jean-Louis Schefer's newly translated The Ordinary Man of Cinema (2016), originally published in 1980, proposes a singular account of the experience of cinema which departs from the principal tendencies of film theory. It has nevertheless had a profound if somewhat invisible influence in film philosophy and theory since its publication, notably in the work of Gilles Deleuze. This essay proposes a synthetic discussion of Schefer's work on film up to The Ordinary Man, arguing that Schefer's work, which draws on his earlier work on painting, construes film as radically non-representational, and as bringing into being, in the spectator, a virtual affectivity corresponding to the distorted and disproportionate bodies and aberrant movements that it presents. I argue that in its recurrent emphasis on the “inchoate” elements in film, and on the “inceptions” of movements that it provokes, Schefer's thought draws implicitly on the Bataillean notion of the informe (formlessness). This return to an impossibility of thought at the heart of thought is among the fundamental insights which Deleuze draws from Schefer in Cinema 2: The Time-image.

A carcinogen-induced premalignant oral lesion model that progresses to oral cancer was used to examine the immunological impact of a 5-week treatment regimen to block programmed cell death protein 1 (PD-1). PD-1 antibody treatment resulted in concurrent, but transient, increases in interleukin (IL)-2, IFN-γ and IL-17, and delayed increases in IL-6 and IL-10 within the lesion-bearing tongue epithelium. In contrast, cytokine secretion by lymph node cells of PD-1 antibody-treated mice was lower than for mice treated with control antibodies, with the exception of interferon (IFN)-γ, whose secretion increased late in the treatment period. This delayed secretion of IFN-γ coincided with an increase in CD4+ lymph node cells expressing IFN-γ. Lymph node cells of PD-1 antibody-treated mice reacted to a challenge with lysates of lesions or cancer by early production of IFN-γ, but this rapidly subsided. There also was increased production IL-17 and tumor necrosis factor (TNF)-α in response to the challenge, but the response was greatest by cells of control lesion-bearing mice. Clinical assessment showed an early but transient, stabilization of disease in mice treated with PD-1 antibody. These results show an early beneficial, but time-limited, response to PD-1 antibody treatment, which then fails with continued lesion progression.
Unconventional Approaches Involving Cyclodextrin-Based, Self-Assembly-Driven Processes for the Conversion of Organic Substrates in Aqueous Biphasic Catalysis
Authors: Hapiot Frédéric , Monflier Eric
Published: June 2017

Aqueous biphasic catalysis is a convenient approach to convert organic, partially soluble molecules in water. However, converting more hydrophobic substrates is much more challenging as their solubility in water is extremely low. During the past ten years, substantial progress has been made towards improving the contact between hydrophobic substrates and a hydrophilic transition-metal catalyst. The main cutting-edge approaches developed in the field by using cyclodextrins as a supramolecular tool will be discussed and compared in this short review.

With the rapid development of Internet, the traditional computing environment is making a big migration to the cloud-computing environment. However, cloud computing introduces a set of new security problems. Aiming at the virtual machine (VM) escape attack, we study the traditional attack model and attack scenarios in the cloud-computing environment. In addition, we propose an access control model that can prevent virtual machine escape (PVME) by adapting the BLP (Bell-La Padula) model (an access control model developed by D. Bell and J. LaPadula). Finally, the PVME model has been implemented on full virtualization architecture. The experimental results show that the PVME module can effectively prevent virtual machine escape while only incurring 4% to 8% time overhead.
Deciphering Structural Photophysics of Fluorescent Proteins by Kinetic Crystallography
Authors: Bourgeois Dominique
Published: June 2017

Because they enable labeling of biological samples in a genetically-encoded manner, Fluorescent Proteins (FPs) have revolutionized life sciences. Photo-transformable fluorescent proteins (PTFPs), in particular, recently attracted wide interest, as their fluorescence state can be actively modulated by light, a property central to the emergence of super-resolution microscopy. PTFPs, however, exhibit highly complex photophysical behaviours that are still poorly understood, hampering the rational engineering of variants with improved performances. We show that kinetic crystallography combined with in crystallo optical spectroscopy, modeling approaches and single-molecule measurements constitutes a powerful tool to decipher processes such as photoactivation, photoconversion, photoswitching, photoblinking and photobleaching. Besides potential applications for the design of enhanced PTFPs, these investigations provide fundamental insight into photoactivated protein dynamics.

Published: June 2017

Rotating bending fatigue tests have been performed to evaluate the corrosion fatigue performance and its influence factors of 7075-T7351 Al alloy in different media, namely air and a 5.0 wt % NaCl aqueous solution. All samples were coated by microarc oxidation (MAO) coating technology; some samples were followed by an epoxy resin pore-sealing treatment. Microscopic analyses of the surfaces and fracture cross-sections of samples were carried out. The results reveal that the sample with a MAO coating of 10 μm thickness and pore-sealing treatment by epoxy resin possesses optimal corrosion fatigue performance in the different media. The MAO coating with a pore-sealing treatment significantly improves the corrosion fatigue limit of 7075-T7351 Al alloy.

Egg lectins occur in a variety of animals ranging from mollusks to vertebrates. A few examples of molluscan egg lectins have been reported, including that of the sea hare Aplysia kurodai; however, their biological functions in the egg remain unclarified. We report the isolation, determination of primary structure, and possible functions of A. kurodai lectin (AKL) from the egg mass of A. kurodai. We obtained AKL as an inseparable mixture of isoproteins with a relative molecular mass of approximately 32 kDa by affinity purification. The hemagglutinating activity of AKL against rabbit erythrocytes was inhibited most potently by galacturonic acid and moderately by xylose. Nucleotide sequencing of corresponding cDNA obtained by rapid amplification of cDNA ends (RACE) allowed us to deduce complete amino acid sequences. The mature polypeptides consisted of 218- or 219-amino acids with three repeated domains. The amino acid sequence had similarities to hypothetical proteins of Aplysia spp., or domain DUF3011 of uncharacterized bacterial proteins. AKL is the first member of the DUF3011 family whose function, carbohydrate recognition, was revealed. Treatment of the egg with galacturonic acid, an AKL sugar inhibitor, resulted in deformation of the veliger larvae, suggesting that AKL is involved in organogenesis in the developmental stage of A. kurodai.
Investigation on Mechanical Behavior of Biodegradable Iron Foams under Different Compression Test Conditions

Published: June 2017

Biodegradable metal foams have been studied as potential materials for bone scaffolds. Their mechanical properties largely depend on the relative density and micro-structural geometry. In this work, mechanical behavior of iron foams with different cell sizes was investigated under various compression tests in dry and wet conditions and after subjected to degradation in Hanks’ solution. Statistical analysis was performed using hypothesis and non-parametric tests. The deformation behavior of the foams under compression was also evaluated. Results show that the mechanical properties of the foams under dry compression tests had a “V-type” variation, which is explained as a function of different geometrical properties by using a simple tabular method. The wet environment did not change the compression behavior of the iron foams significantly while degradation decreased the elastic modulus, yield and compression strengths and the energy absorbability of the specimens. The deformation of open cell iron foams under compression is viewed as a complex phenomenon which could be the product of multiple mechanism such as bending, buckling and torsion.

Published: June 2017

Different surfaces were obtained by Plasma Electrolytic Oxidation (PEO) of the Ti–6Al–4V alloy; followed by hydrothermal treatment (HT). The surfaces were studied by scanning electron microscopy (SEM); Energy Dispersive Spectroscopy (EDS); X-ray Diffraction (XRD); Brunauer–Emmett–Teller (BET) absorption and abrasion wear tests. The resulting surface contains hydroxyapatite (HA); which contributes to superior implant osseointegration. Treated implants were introduced into rabbits and their osseointegration was studied after two and six months. It was established that implant surface area increases due to pore formation. Pore formation and hydroxyapatite on the surface of the implant qualitatively change contact osseogenesis processes with reduced duration of osseointegration of implants. The treatment of the surface of the implants by the combination of PEO and HT provided better results in the medico-biological investigations than PEO alone. Abrasion tests demonstrated that the HA will be preserved after the procedure of implantation; ensuring effective osseointegration.
Rapid Prototyping of a Micromotor with an Optical Rotary Encoder
Authors: Pang Da-Chen , Lai Yi-Wei
Published: June 2017

This study proposed a rapid prototyping fabrication method for micromotors that allowed us to develop both 1 mm and 1.5 mm diameter permanent-magnet synchronous motors (PMSMs) with an optical rotary encoder. First, an integrated electroforming method was proposed for combining stator housing and flexible print circuit (FPC) coils to ease the manufacturing and assembly of micromotor components. This is particularly useful in the production of prototypes or small volumes of units. Second, an optical encoder was used to detect the rotational angle by means of a reflective code disk, an optical fiber, and a photo-detector. The micromotor was built with a code disk and an optical fiber. The code disk was designed to match the optical fiber and was made by photolithography and sputtering. Both the 1 mm and 1.5 mm diameter motors successfully achieved a rotational speed over 20,000 RPM and due to a 50 µm diameter optical fiber core, the encoders showed a resolution of 12 and 18 pulses per revolution (PPR), respectively.

Peppers are consumed all over the world due to the flavor, aroma, and color that they add to food. Additionally, they play a role in human health, as they contain a high concentration of bioactive compounds and antioxidants. The treatments used were an absolute control, Cs-PVA, and four treatments with 0.02, 0.2, 2, and 10 mg (nCu) g−1 (Cs-PVA). The application of Cu nanoparticles in chitosan-PVA hydrogels increases the content of capsaicin by up to 51% compared to the control. This application also increases the content of antioxidants ABTS [2,2′-azino-bis (3-ethylbenzothiazolin-6-sulfonic acid)] and DPPH (2,2-diphenyl-1-picrylhydrazyl), total phenols and flavonoids (4%, 6.6%, 5.9%, and 12.7%, respectively) in jalapeño pepper fruits stored for 15 days at room temperature; under refrigeration, it increases DPPH antioxidants, total phenols, and flavonoids (23.9%, 1.54%, and 17.2%, respectively). The application of Cu nanoparticles in chitosan-PVA hydrogels, even when applied to the substrate, not only has an effect on the development of the jalapeño pepper crop, but also modifies the post-harvest characteristics of the jalapeño pepper fruits.
