Published: November 2018

Abstract
A couple SPH-FEA modelling technique is investigated to determine the suitability of the mentioned technique to model offshore cutting operation of Abrasive Water-jet (AWJ) cutting. For model validation, results are compared to analysis available in literature on abrasive water-jet machining. An AWJ cutting a ductile metal sample with certain thickness and property is modeled and simulated to investigate the impact response and parameters that influence, including impact speeds. To overcome the difficulties of fluid—solid interaction and extra-large deformation problem using finite element method (FEM), the SPH-coupled FEA modeling for abrasive waterjet cutting simulation is presented, in which the abrasive waterjet is modeled by SPH particles and the target material is modeled by Finite Element. Validation is achieved by comparing the model against numerical result available in literature. The coupled SPH-FEA model is compared against previously published results and validated. Then, studies is conducted to determine the erosion rate effect due to change in abrasive types and different flow rates. The depth of penetrations and erosion rate is extracted for analysis. It can be seen that the generated SPH-FEA method is able to simulate the condition of AWJ cutting of offshore steel structure material up to 250 MPa. The fluid-structure interaction in AWJ cutting where the erosion-cutting of steel target material is highly non-linear was modelled by full coupled SPH/FEA. This research demonstrates that the approach can be extended to full-scale AWJ-steel structure cutting simulation through appropriate management of SPH/FEA resources. With a validated model, researchers will be able to manipulate the variables in AWJ to study the efficacy of cutting optimization in offshore decommissioning operations. The novelty in this paper is that the coupled SPH-FEA technique to model Abrasive Water Jetting is used to model cutting of offshore structures. This validated coupled SPH-FEA modelling technique will enable engineers to design new cutting tools that can improve efficiency and efficacy of next generation offshore cutting tools.
Seeking the Proper Decommissioning Method in Gross Split Era
Authors: Junedi Karyadi 
Published: November 2018

AbstractPT Pertamina Hulu Energi Offshore North-West Java (PHE ONWJ) presently operates a fleet of more than 200 fixed offshore platforms and nearly three quarters of these platforms have been in operation for more than 30 years. Under newly implemented Gross Split Production Sharing Contract (PSC) scheme, PHE ONWJ is driven to seek an effective and efficient method for offshore platform decommissioning. Three offshore decommissioning options, i.e. Total Removal for Onshore Disposal, Total Removal for Rig-to-Reef, and Leave-in-Situ for Mariculture are examined closely. A qualitative evaluation, which involves comparing the total expected cost of each option against its total expected benefits, is conducted in view of decommissioning drivers, i.e. Safety, Environment, Technical, Cost, and Social Impact to other sea user and community. The evaluation of the expected cost of each decommissioning options is presented. The first two options are subjected to high cost activities e.g. platform removal; mobilization and demobilization of derrick barge; and material disposal onshore or reefing site. The Leave-in-Situ for Mariculture option, on the other hand, is not exposed to those activities as it leaves the retired platform on its existing location and turns the structure into the site for offshore cage system fish farming. This is significant because in the Gross Split PSC scheme, PHE ONWJ is expected to be more prudent and focus on cost efficiency. The social impact of the Mariculture method is potentially important considering the rapid growing of global per capita fish consumption and the fact that there are no offshore cage systems fish farming using retired offshore platform in Indonesian waters or even Southeast area yet. The suitability of the proposed mariculture site of Offshore North West Java waters is further evaluated against the guidelines from the Food and Agriculture Organization of the United Nations (FAO). The Mariculture method can be not only the most cost efficient solution for offshore platform decommissioning, but also providing alternative technique to increase marine fish production.

Abstract
The development of offshore upstream oil and gas industry in Indonesia was established in 1971 through the discovery of Arjuna Field in Nothern Java Sea by Atlantic Richfield Indonesia, Inc. (ARII). In 2017, 637 offshore platforms are installed in Indonesian water. Of these, 601 platforms are active and 36 of them are not. Furthermore, 17 of ready to be decommissioned platforms are now in write-off process. A research is conducted to study the policy and institution of offshore platform decommissioning with objective to improve the performance of navigational safety and state-owned asset management. Data of accidents in offshore installations showed some accidents between ship and production facility. These number of accidents in the water region is the key performance indicator (KPI) of authorized institution in Marine Affair which is related to navigational safety. Meanwhile, from state-owned asset management perspective, the success of offshore platform decommissioning will broaden the spectrum of experience of respective institutions, especially in area of Oil and Gas Asset Management. The study is part of applied research which utilized qualitative and quantitative methods. For pilot study, a stakeholder analysis was conducted to identify the key stakeholders of the offshore platform decommissioning program. Six variables were highlighted as latent variables in offshore platform decommissioning: (1) policy, (2) institution, (3) decommissioning method, (4) financing, (5) performance of navigational safety, and (6) performance of state-owned asset management. A conceptual framework was developed for modelling how each variable linkage to build an interaction model between policy, institution, decommissioning method, and financing to improve the performance of navigational safety and state-owned asset management. Structural Equation Model Partial Least Square (SEM PLS) was adopted for this purpose.

Background:To explore the cytotoxic and apoptotic activity of the pierisin-6 protein in HPV HeLa and HepG2 cell lines.Methods:In this study, isolation, and purification of cytotoxic Prierisin-6 from the larvae of Pieris napi by affinity column chromatography techniques. Characterization of full-length mRNA of pierisin-6 gene was performed using 3’/5’ RACE PCR. The quantitative RT-PCR used to study the developmental stage-specific expression of pierisin-6 mRNA. The most effective concentration of Pierisin-6 protein was determined by measuring cell proliferation. Apoptosis was assessed using AO/Et-Br, Propidium Iodide, and Rhodamine 123 assays, whereas protein levels of caspase 3, cytochrome C were evaluated by ELISA method. Pierisin-6 induced cell cycle arrest was determined using Propidium iodide by FACS.Results:In this study, Pierisin-6, a novel apoptotic protein was found to have cytotoxicity against HeLa, HepG2 human cancer cell lines and L-132 human lung epithelial cell line. Among the target cells, HeLa was the most sensitive to Pierisin-6. Flow cytometry analysis confirms an increased percentage of apoptotic cells in sub G1 phase and cell cycle arrest at S phase. Alteration in the transmembrane potential of mitochondria, Cytochrome c released from the mitochondrial membrane, and caspase substrate assay demonstrated the cleavage of Ac- DEVD-pNA signifying the activation of Caspase-3. These findings suggested that Pierisin-6 significantly induce apoptosis in HeLa and HepG2 cells and is attributed mainly through a mitochondrial pathway by activation of caspases. The developmental and stage-specific expression of pierisin-6 mRNA was one thousand-fold increased from second to third instar larvae and gradually declined before pupation.Conclusion:Pierisin-6 represents a promising therapeutic approach for liver cancer patients.
Cryopreservation of Orchids – A Review
Authors: Kaur Saranjeet 
Published: November 2018

<P>Background: The orchids are one of the beautiful creations of nature which stand apart from any other assemblage of flowering plants. They are highly evolutionary and ecologically significant group of plants that have effectively occupied almost every habitat on the earth. Indiscriminate collections and extermination of their natural habitats have threatened many species of orchids with extinction, resulting in a severe reduction of their genetic resources in nature according to recent patents. It is necessary to adopt sound scientific protocols for the preservation of orchid species.Method:This cost-effective technique provides large storage time for the conservation of germplasm. Presently, efforts have been made to explore various cryopreservation techniques utilized so far and factors affecting the longevity of the propagules (in vivo and in vitro) while cryopreserving them. The sample to be cryopreserved is freeze-preserved in two ways, a) stepwise at two different subzero temperatures and b) in the rapid method, the samples are placed directly in the liquid nitrogen. </P><P> Results: The orchid seeds and pollen are the most suitable propagules for cryopreservation of orchids due to their minute size and less space requirement.Conclusion:Among the tissues (such as seeds, pollen, protocorms etc.) seeds are the most reliable. The present article reviews the cryopreservation techniques and factors effecting the cryopreservation, for in vitro conservation of orchid gene pool.</P>
Diffuse Appearance of Red Bone Marrow on MRI Mimics Cancer Metastasis and Might be Associated with Heavy Smoking
Authors: Sakamoto Akio , Otsuki Bungo , Okamoto Takeshi , Goto Takayuki , Yoshimura Tetsuro , Matsuda Shuichi 
Published: November 2018

Background:
Red bone marrow develops early in life and converts into yellow bone marrow with aging. Reconversion occurs when yellow bone marrow reconverts into red bone marrow due to increased oxygen demands.

Objective:
Diffuse appearance of red bone marrow on Magnetic Resonance Imaging (MRI) is rarely encountered.

Materials and Methods:
Seven patients, five male and two female, with the diffuse appearance of red bone marrow were evaluated. The average age was 71.4 (47-86) years old. All patients had been referred based on a working diagnosis of cancer metastasis. All patients were eventually rediagnosed with bone marrow reconversion.

Results:
Spinal MRI was evaluated in all patients, including the whole spine in four patients and lumbar spine in three patients. Six patients had slight anemia or close to the lower limit of normal hemoglobin (within 1mg/dl). Six patients were heavy smokers, having more than 20 cigarettes per day. Four patients had a history of stomach or bladder cancer (2 cases each). MRI revealed red bone marrow with a diffuse appearance and low signal intensity on T1- and T2-weighted images. Compared with the spinal cord/conus, the red bone marrow appeared isointense in about half of the cases, and in the other cases, the intensities were either slightly high or low. The signal of yellow bone marrow was isointense with the retroperitoneal fat.

Conclusion:
Diffuse red marrow can be difficult to differentiate from cancer metastasis. Compared to the MRI, signal intensity of the cord/conus is useful in the diagnosis of red marrow. Slight anemia may also be present. Heavy smoking might be related to the appearance of diffuse red marrow.

O artigo "O CR-P nas eleições de 1998 para o Governo Gaúcho. A vitória da contra-hegemonia" tem por objetivo apresentar os resultados iniciais da pesquisa sobre as eleições de 1998 no Rio Grande do Sul para o governo do estado. A análise vai ser desenvolvida a partir do conceito de Cenário de Representação Política (CR-P) e da hipótese de agenda setting. A hipótese central do trabalho é a de que alguns meios de comunicação construíram um
cenário para garantira vitória do candidato Antônio Britto (PMDB) já no primeiro turno, mas a construção de um outro CR-P, alternativo, levou o candidato Olívio Outra (PT) ao segundo turno e à vitória nas eleições.
A perna coxa da tecnologia. - Fantasias totalitárias dos Náufragos da Polissemia na Cibercultura
Authors: Pena Felipe 
Published: November 2018

Levando em conta os símbolos de uma das representações mitológicas mais significativas sobre a técnica, a de Hefestos, o deus coxo, tentamos resgatar o alerta sobre a ambiguidade e as limitações da tecnologia. Nosso principal objetivo é discutir algumas das imagens da subjetividade no âmbito
da cibercultura e suas conseqüências nas formas de socialização e apreensão da realidade na contemporaneidade. Partimos da hipótese de que sob o modelo de sujeito descentrado e sem limites presente no imaginário
das novas tecnologias, há um indivíduo que chamamos de náufrago da polissemia, ou seja, sob a metáfora dos mares polissêmicos, na verdade naufraga um sujeito incapaz de dar conta dessas múltiplas significações. E esse naufrágio pode revelar fantasias totalitárias de controle ilimitado sobre
a vida humana, com desejos de transcender, inclusive, a própria morte.
Ficção Científica: uma narrativa da subjetividade homem-máquina
Authors: Oliveira Fátima Régis de 
Published: November 2018

As novas tecnologias de informação e a comunicação mediada por computador desafiam as fronteiras modernas que definiam o humano como sujeito natural, pensante e autônomo. Ao violar essas fronteiras, as novas tecnologias produzem seres híbridos e mundos possíveis, antes restritos às narrativas de ficção científica. Partindo das interrogações corno a ficção
científica conquistou a Atualidade e como nos tornamos ciborgues, o artigo desenvolve duas hipóteses complementares. A primeira aposta que a ficção científica é uma narrativa que problematiza as fronteiras entre subjetividade, tecnociência e espaço-tempo como estratégia de interrogar o humano. A segunda hipótese crê que ao pôr em questão as fronteiras ontológicas e epistemológicas modernas, as novas tecnologias permitiram os hibridismos que atualizam o ciborgue como devir humano e elegem a ficção científica como ficção da Atualidade.
Do problema do iconismo à ecologia da representação pictórica: indicações metodológicas para a análise do discurso visual
Authors: Picado José Benjamim 
Published: November 2018

Buscamos avaliar a forte incidência que a discussão sobre imagens nos estudos comunicacionais sofreu de um discurso fortemente marcado pela predominância de categorias próprias ao campo das teorias da linguagem; reconhecendo este movimento de incorporação dos saberes lingüísticos, para a avaliação das estruturas discursivas próprias aos ícones visuais,
propomos um viés alternativo de análise, fundado na compreensão da relação entre as estruturas de sentido próprias às representações visuais e aquilo que constitui uma matriz originariamente perceptiva dos fatos visuais.
Jean Cocteau: comunicação visual e imaginário mitopoiético
Authors: Rahde Maria Beatriz Furtado 
Published: November 2018

Numa obra plena de multifaces, Jean Cocteau (1889-1963) foi, sem dúvida, o grande poeta do século XX, tanto na literatura, no teatro, nas artes gráfico/ plásticas, como na arte visual cinematográfica. Cocteau sempre fez poemas de suas manifestações criativas, pelas quais perpassavam o imaginário mítico, os contos de fadas, a filosofia, com sua concepção do estético, do fantástico na comunicação visual e nas relações humanas. A Bela e a Fera, obra cinematográfica de sua autoria, com base no conto original de Madame de Beaumont estimula o espectador nesses elementos citados, pois, certamente ninguém melhor do que o autor conhecia o simbólico, a fantasia,
a poesia das evocações imaginárias. Este texto busca refletir sobre a comunicação visual e a cultura mítica da cinematografia de Jean Cocteau, o poeta do surrealismo e do imaginário, na concepção deste conto de fadas filmado, buscando relações entre a modernidade e o imaginário mitopoiético de sua obra.

Published: November 2018

Abstract
Among other forms, iron contained in soil is a component of magnetic minerals, both primary and secondary ones, produced by various soil forming processes. The composition of the soil magnetic fraction, characterised by a magnetic susceptibility, is the consequence of its origin. The character of susceptibility changes along the analysed chernozems’ profiles indicates a similarity of the parent rock, as well as the pedogenic processes forming the chernozems from the territories of Poland and the Ukraine. The influence of anthropogenic factors could be seen in the increased susceptibility within the humus horizon of the degraded chernozem.
