Understanding basement fracture architecture in Padra Field, South Cambay Basin, India, through full-azimuth imaging
Authors: Ghosh Abhinandan
Published: April 2019

Detection and characterization of fractures in reservoirs is of great importance for maximizing hydrocarbon productivity and recovery efficiency. Fractures play an important role in the producibility of unconventional reservoirs such as basement reservoirs. Basement reservoirs are typically found within metamorphic and igneous rock underlying a sedimentary basin, where faulting and tectonic uplift has led to creation of a fracture network. For fracture characterization, integration of information from seismic and nonseismic data such as cores and/or formation microimaging (FMI) logs is essential. Various seismic attributes such as coherency and curvature that are derived from reflection seismic data have been used for more than a decade to detect faults and fractures. In advanced seismic fracture detection technology, automatic fault extraction (AFE) from diffraction seismic data (discontinuity volume) more effectively detects finer scale features in seismic data. We demonstrate the utility of this methodology with an application to seismic data from the Padra Field, South Cambay Basin, India, where the basaltic Deccan Trap forms the basement, and hydrocarbons are produced from basement fractures. Diffraction imaging was applied during processing of the full-azimuth 3D-3C seismic data that cover this field. Using wavefield decomposition in the subsurface local angle domain, separate reflection (specular) and diffraction data volumes were produced. The high-resolution specular stack data imaged a prominent reflector well below the trap top, which is not visible in conventional seismic reflection data. Diffraction stack data also provided higher resolution fault definition and enhanced imaging of spatially consistent geological discontinuities. Subsequent application of the AFE technique to diffraction-imaged data yielded sharp and crisp definition of faults and fractures. We also performed velocity variation with azimuth analysis of 3D angle-azimuth reflection gathers to generate a fracture orientation map. Both sets of results were validated by fractures detected in FMI logs from wells in the field.

Arctic Nation
Authors: Blum Hester
Published: April 2019

This provocation considers the relationship between the United States and the Arctic. America might be understood as an Arctic nation not just because of its political and resource claims in the polar region but because the nation has become both environmentally and politically inhospitable to human life. The polar regions are no longer climate outliers on the planet, remote regions exceptionally hostile to human life. The United States could do more to recognize forms of geopolitical organization that do not presume continental supremacy; that loose the “territory” from “territorial seas”; that understand the cryosphere as a model for new forms of relation and collaboration; that turn to Indigenous knowledge and traditional ecological knowledge for guidance.
Liposome-Based Biosensors Using Phytase Immobilized on Polypyrrole Films for Phytic Acid Determination
Authors: Rodrigues Valquiria C , Moraes Marli L , Soares Juliana C , Souza Adriano L , Soares Andrey C , Oliveira Osvaldo N , Gonçalves Débora
Published: April 2019

Phytase was immobilized onto electrochemically prepared polypyrrole (PPy) films either in the free, native form (Phy) or encapsulated in phospholipid dipalmitoyl phosphatidylglycerol (DPPG) liposomes (lipo-Phy). The incorporation of Phy into the PPy matrix was verified using cyclic voltammetry, polarization-modulated infrared reflection absorption spectroscopy, and scanning electron microscopy. PPy, PPy/Phy and PPy/lipo-Phy films were characterized by amperometric experiments in phytic acid (PA) solutions at different concentrations. PPy/lipo-Phy showed a more sensitive response, which was confirmed in stable current vs concentration and current vs time curves, and by a superior analytical performance with a saturation concentration of 3.0 mmol L−1 PA. A multidimensional projection technique, IDMAP, was used to project the voltammetric data, and confirmed the higher selectivity for PPy/lipo-Phy by distinguishing PA in a specific range of concentrations.
Performance comparison of aperture-less and confocal infrared microscopes
Authors: Sandt C. , Dionnet Z. , Toplak M. , Fernandez E. , Brunetto R. , Borondics F.
Published: April 2019

We compared hyperspectral infrared raster maps and images for contrast, definition and resolution of the same
samples recorded with a confocal microscope coupled with a synchrotron radiation source vs a Focal Plane Array (FPA)
detector equipped microscope. Biological samples (hair and skin sections) and astrophysics samples (meteoritic grains)
were used. The samples presented are a few microns in size, such as embedded particles, a single unique cell or thin
layer. Our results show that the actual spatial resolution and contrast of FPA images were lower than spectral maps from
the confocal microscope. The FPA microscope also produced measurements that lacked accuracy: size of sample
features and peak intensity were inaccurately estimated. More surprisingly, the intensity of absorption peaks in the FPA
images was lower than the intensity measured from the same sample with a confocal microscope. Our measurements
underlined the complementarity of FPA and confocal microscopes. FPA can be used to quickly measure the overall
composition of a sample and detect the distribution of its components, but may fail measuring the exact chemical
composition of the small features and may not detect weak spectral differences between adjacent positions. The
averaging effect of aperture-less systems not only affects image resolution but also lowers their spectral accuracy.
Confocal microscopes are inherently slower but give a more accurate measurement of the local composition at the
diffraction limit.
Enhanced conventional method is as precise as navigation for distal femur resection during total knee replacement: a randomized controlled trial
Authors: Bhimani Rohan , Bhimani Fardeen , Singh Rohan Bir , Singh Preeti
Published: April 2019

Introduction: The purpose of this prospective study was to determine the accuracy of distal femoral cut and femoral component placement in the coronal plane with the enhanced conventional technique when compared to computer navigation during total knee replacement (TKR).

Methods: In total, 475 total knee arthroplasties (TKA) were analyzed (200 optimized conventional TKAs and 275 navigated TKAs) for postoperative mechanical alignment or hip-knee-ankle angle and femoral component coronal alignment and compared between the two groups

Results: Mean femoral component coronal alignment was not significantly different (p=0.35) when navigation and enhanced conventional groups were compared. There was no significant difference in the mean femoral component coronal alignment between knees with a valgus correction angle (VCA) <5° (p=0.28), knees with VCA 5°-7° (p=0.48) and knees with >7° (p=0.09). No significant difference was noted in the mean femoral component coronal alignment between knees with varus deformity <10° (p=0.19), varus deformity 10°-20° (p=0.72) and valgus deformity (p=0.35).

Conclusions: Using the enhanced conventional technique in each patient to perform distal femoral cut during total knee arthroplasty can help achieve the coronal alignment of the femoral component comparable to navigation technique.

Malaria elimination transmission and costing in the Asia-Pacific: Developing an investment case
Authors: Shretta Rima , Silal Sheetal Prakash , Celhay Olivier J. , Gran Mercado Chris Erwin , Kyaw Shwe Sin , Avancena Anton , Fox Katie , Zelman Brittany , Baral Ranju , White Lisa Jane , Maude Richard James
Published: April 2019

Background: The Asia-Pacific region has made significant progress against malaria, reducing cases and deaths by over 50% between 2010 and 2015. These gains have been facilitated in part, by strong political and financial commitment of governments and donors. However, funding gaps and persistent health system challenges threaten further progress. Achieving the regional goal of malaria elimination by 2030 will require an intensification of efforts and a plan for sustainable financing. This article presents an investment case for malaria elimination to facilitate these efforts.

Methods: A transmission model was developed to project rates of decline of Plasmodium falciparum and Plasmodium vivax malaria and the output was used to determine the cost of the interventions that would be needed for elimination by 2030. In total, 80 scenarios were modelled under various assumptions of resistance and intervention coverage. The mortality and morbidity averted were estimated and health benefits were monetized by calculating the averted cost to the health system, individual households, and society. The full-income approach was used to estimate the economic impact of lost productivity due to premature death and illness, and a return on investment was computed.

Results: The study estimated that malaria elimination in the region by 2030 could be achieved at a cost of USD 29.02 billion (range: USD 23.65-36.23 billion) between 2017 and 2030. Elimination would save over 400,000 lives and avert 123 million malaria cases, translating to almost USD 90 billion in economic benefits. Discontinuing vector control interventions and reducing treatment coverage rates to 50% will result in an additional 845 million cases, 3.5 million deaths, and excess costs of USD 7 billion. Malaria elimination provides a 6:1 return on investment.

Conclusion: This investment case provides compelling evidence for the benefits of continued prioritization of funding for malaria and can be used to develop an advocacy strategy.

The PKK's Newroz: Death and Moving Towards Freedom for Kurdistan
Authors: Rudi Axel
Published: April 2019

The PKK's patronage of Newroz has changed its historical and contextual development. Previous studies have shown how the PKK made Newroz into a festival for Kurdish ‘counter hegemony', but have not paid sufficient attention to the performance of the celebration itself and its concurrent role in the PKK's political universe. This article presents an ethnographic study of how Newroz became a vehicle for disseminating the PKK's political ideology, and how it reveals cosmological ideas about agency, time, social formations, and the eventuality of freedom. The paper argues that through celebrating under the auspices of ‘the martyrs', who are incorporated in the figure of Abdullah Öcalan, the dead become re-animated and promise the potential for the arrival of a new, free time as well as illustrate the social organization and personal agency needed to achieve it. The paper uses this to expand on theories concerning the relation of death to social life, and argues that Newroz shows how the dead may go beyond being vessels for social reproduction, to becoming potentially radically transformative figures. The source material derives from participant observation at Newroz in the PKK-controlled Qandil Mountains in Iraq in 2017, and from interviews and secondary sources from the celebration in the Maxmur refugee camp.
Desarrollo de competencias y docencia de conocimientos históricos en grados universitarios fuera del ámbito de la Historia
Authors: Blasco Martel Yolanda , Ibarz Gelabert Jordi , Lo Cascio Paola , Monterde Oscar , Maynou Felker Marc
Published: April 2019

Las asignaturas que desarrollan conocimientos históricos han llegado a ser transversales en muchas titulaciones no específicamente históricas. El conocimiento del pasado permite desarrollar un conjunto de competencias en diversas titulaciones como Economía, Administración y Dirección de Empresas, Sociología, Ciencias Políticas... Esto ofrece nuevos retos a la docencia de contenidos históricos. En este caso queremos trabajar la experiencia con las asignaturas de historia dirigidas a tres grados que se imparten en la Universidad de Barcelona. Estas asignaturas tienen muchos contenidos en común, aunque las competencias específicas y transversales de las mismas no coincidan totalmente. Esto permite reflexionar sobre: a) las posibilidades que tiene una asignatura de historia en diferentes grados para desarrollar competencias, b) la visión acerca de la flexibilidad que ofrece el conocimiento histórico que permite contextualizar diferentes problemas que afectan al mundo profesional, y c) la adquisición y evaluación de las competencias transversales en la UB. En el trabajo se analizan los programas de dichas asignaturas, las competencias que se desarrollan y la experiencia docente. El objetivo último es explorar cuáles son las habilidades que los estudios de aspectos históricos permiten adquirir a estudiantes de grados no relacionados con los propios de la disciplina.

‘Vampires don’t do dishes’: Old myths, the modern world, horror and the mundane in What We Do in the Shadows (2014)
Authors: Wright Andrea
Published: April 2019

The New Zealand horror-comedy What We Do in the Shadows (2014) emerged at a time when contemporary cinema had been showing a renewed and sustained interest in vampire fiction. Whilst it was not the first to offer a humorous reworking of vampire mythology, this parody is striking for it comes from a strong tradition in New Zealand cinema of disrupting genres, an approach that can be observed, for instance, in Peter Jackson’s early work. What We Do in the Shadows creatively utilizes generic tropes and intertextual references whilst relocating supernatural creatures of the old world into a contemporary Wellington. As this article argues, the comic potential is opened up in the film by a particular convergence of the spectacular and the mundane. In this environment, blood-drinking and the practicing of the dark arts sit alongside everyday domestic tasks and cleaning rotas in a household of vampires. The film, it will be established, not only challenges and disrupts established horror genre conventions and expectations by repositioning them in a sitcom format, it also playfully engages with representations of masculinity and the homosocial in a house-share environment. In addition, by positioning the narrative in a New Zealand context, the film is able to localize the myths and stories of the old world and thus further destabilize recognized generic traditions.
New Extractive Spectrophotometric Method Development and Validation for the Estimation of Danazol in Pharmaceutical Formulations
Authors: Devi K. Rama , Kumar K. Kiran , Krishnaveni G.
Published: April 2019

A simple, sensitive, selective, accurate and economical spectrophoto-metric method have been described in the present work for the deter-mination of danazol in bulk drug and pharmaceutical formulations (tablets). Method is based on the formation of yellow coloured ion-association complexes between danazol and alizarine red S in acid medium followed by their extraction with chloroform, exhibiting absorption maxima at 430 nm, and obeying Beer′s law in the concen-tration range of 5-30 μg/mL. Statistical analysis of the results of the proposed methods reveals high accuracy and good precision. The proposed methods could be successfully extended to the commercial pharmaceutical formulations containing danazol.
Maternal Uniparental Disomy 14 (UPD14) Identified by Clinical Exome Sequencing in an Adolescent with Diverticulosis
Authors: Chan Alvin P. , Mulatinho Milene , Iskander Paul , Lee Hane , Martinez-Agosto Julian A. , Yeh Joanna
Published: April 2019

Pediatric diverticular disease is extremely rare, with most cases associated with connective tissue disorders. We report an adolescent boy with syndromic features who presented with acute complicated sigmoid diverticulitis. Clinical exome sequencing analysis detected a 6.5-Mb region of homozygosity on chromosome 14, consistent with partial maternal uniparental disomy. Analysis of this region did not identify rare homozygous variants but included several imprinted genes that were candidates for the observed phenotypes. The pediatric clinical presentation of diverticulosis in this patient has not been previously described in maternal uniparental disomy of chromosome 14 and adds to the phenotypic spectrum of the syndrome.
Understanding Fall-Risk Factors for Inuvialuit Elders in Inuvik, Northwest Territories, Canada
Authors: Frigault Julia S. , Giles Audrey R.
Published: April 2019

Older Indigenous adults in Canada experience disproportionately poorer health outcomes than older non-Indigenous adults. Current fall-prevention literature suggests that older Indigenous adults have higher rates of falls and fall-related injuries; however, no information exists on older Inuit adults’ experience with falls. Using the social determinants of Inuit health (SDoIH) as a conceptual framework, this research sought to understand which of the SDoIH are believed by stakeholders (i.e., local fall prevention programmers [LFPPs] and Inuvialuit Elders) to affect most the likelihood of older Inuvialuit adults’ falls. The findings from the 12 semi-structured interviews and participant observations show that factors related to personal health status and conditions, personal health practices and coping skills, physical environments, social support networks, and access to health services increase older Inuvialuit adults’ likelihood of experiencing a fall. Some determinants, however, decrease their likelihood of experiencing falls (health practices, coping skills, and access to health services), and others, such as culture, were perceived as having little influence on falls. Specific cultural practices were identified as factors that influence the likelihood of older Inuvialuit adults experiencing a fall; however, the overall Inuvialuit culture was not. In light of these findings, we offer recommendations for LFPPs in Inuvik to implement fall-prevention programs that adequately address the SDoIH influencing older Inuvialuit adults’ fall risk and rates.
“It’s All about the Scenery”: Tourists’ Perceptions of Cultural Ecosystem Services in the Lofoten Islands, Norway

Published: April 2019

The Lofoten Islands in northern Norway face challenges from increasing visitor numbers, congestion, environmental impacts, and growing host-visitor tensions. Benefits include increased local employment and growing revenues. Future tourism policy requires better documentation of the non-economic benefits and values associated with tourism in Lofoten; this information is important to the development of policy and management processes. We conducted 45 in-depth interviews with domestic and international visitors, using the cultural ecosystem services (ES) framework to ascertain the core elements of the tourism experience, as well as views on management needs and development. We probed reflections on place, aesthetics, recreational opportunities, inspiration, social relations, cultural heritage, knowledge, spirituality, and identity by offering a combination of statements and questions. All these categories of cultural ES were important to most visitors. However, the importance of the landscape was paramount. Policy implications include the need to include landscape in ES assessments, to map places of especially high scenic value, and to use the ES framework more extensively to identify and compare non-economic and economic tourism values and benefits.

Published: April 2019

Objetivo: avaliar se existem diferenças significativas entre as técnicas de mensurações digital (utilizando o conceito Digital Smile Design, DSD) e manual (utilizando goniômetro e cefalometria). Métodos: um estudo transversal comparativo foi realizado com uma amostra de 18 indivíduos (sexos masculino e feminino, média de idade de 23 anos) portadores de deformidades dentofaciais diversas. Foram avaliadas mensuração manual, digital (DSD) e cefalométrica de cada um desses indivíduos e comparadas entre si. Os pontos anatômicos mensurados em tecido mole foram o A’ e Pog’. Foram utilizados o coeficiente de correlação de Pearson e o teste t de Student para variáveis com distribuição normal, e o coeficiente de Spearman e o teste de Mann-Whitney para amostras com distribuição anormal, com nível de significância de 5%. Resultados: não foram verificadas diferenças estatisticamente significativas entre os métodos de mensuração manual/digital, manual/cefalométrica e digital/cefalométrica (p > 0,05). Os testes de correlação linear do ponto Pog apresentaram uma correlação muito forte: manual/DSD (r = 0,93), manual/cefalométrica (r = 0,93), digital/ cefalométrica (r = 0,99). No ponto A, as comparações foram: moderada para manual/DSD (r = 0,69); moderada para manual/cefalométrica (r = 0,67); muito forte para digital/cefalométrica (r = 0,96). Conclusões: não existiram diferenças significativas entre as técnicas. Os valores da mensuração DSD são mais correlacionados com a cefalometria do que a técnica manual.

Published: April 2019

Os traumas estão entre as principais causas de morte e morbidade no mundo. Entre os diversos tipos, o trauma de face se destaca como um dos mais importantes, uma vez que apresenta repercussões emocionais, funcionais e possibilidade de deformidades permanentes. Sendo assim, o presente estudo busca identificar a etiologia e a prevalência das fraturas faciais no Serviço de Cirurgia e Traumatologia Bucomaxilofacial de um hospital de referência em um município do extremo sul catarinense, entre os anos de 2003 e 2015. Foram analisados 1.822 casos de traumas faciais atendidos no ambulatório de Cirurgia e Traumatologia, no período entre janeiro de 2003 e dezembro de 2015. A faixa etária mais atingida foi de 21 a 30 anos, representando 32,5% da amostra. Os homens foram os responsáveis por 66,6% dos atendimentos; enquanto as mulheres, 33,4%. Os traumas relacionados a acidentes automobilísticos foram os mais prevalentes (22,2%). O osso mais fraturado foi o nasal (37,8%). A incidência de fraturas faciais pode ser reduzida por medidas educativas, como o uso rotineiro do cinto de segurança e do capacete, pelo menor consumo de álcool, respeitando os limites de velocidade, e por estratégias para lidar com situações hostis, no intuito de evitar a crescente violência interpessoal.

Published: April 2019

Introdução: a cefalometria mostra-se importante no planejamento de cirurgias ortognáticas; porém, está sujeita a variações na posição natural da cabeça (PNC), condição que pode prejudicar o planejamento e o resultado final. Objetivo: esse trabalho teve como propósito avaliar a PNC de pacientes Classe III durante as tomadas cefalométricas, no intuito de verificar possíveis alterações de posicionamento e angulação dos seus pontos craniométricos. Métodos: foram feitos registros fotográficos em nove pacientes em PNC. Em seguida, os traçados cefalométricos foram sobrepostos às fotografias, numa proporção de 1:1. Após a sobreposição, demarcaram-se seis pontos (glabela, pró-nasal, subnasal, lábio superior, lábio inferior e pogônio mole), e as distâncias entre os pontos das duas imagens foram mensuradas e avaliadas. Resultados: todos os pontos craniométricos das cefalometrias apresentaram-se divergentes das fotografias, havendo diferenças nas medições lineares (de 1 a 16 mm) e angulares (de -1° a -9°) dos pontos cefalométricos. Mulheres demonstraram maior disparidade, bem como pacientes altos demonstraram maior variação de posição. Conclusão: todos os pacientes apresentaram variação de posicionamento da cabeça durante a tomada cefalométrica; a inclinação foi maior nas mulheres e nos pacientes mais altos e o tamanho da protrusão mandibular não influenciou o grau de inclinação.

Background: Fibromyalgia syndrome (FMS) is an extra-articular rheumatological disease, characterized by widespread pain and somatic symptoms. The etiology has not yet been clarified. Oxidative stress may play an important role in FMS etiology. Thiol group is a very strong antioxidant. We aimed to investigate whether thiol/disulfide homeostasis in FMS is altered or not. Material and methods: A total of 80 female FMS patients and 64 healthy female control individuals were included in this study. Thiol and disulfide values were measured by Erel’s novel methods. Results: Native thiol (330.6 ± 46.1 vs. 356.8 ± 55.5 μmol/L, p = 0.005) and native thiol/total thiol (89.4 ± 3.2 vs. 93.3 ± 4.0, p < 0.001) levels of FMS patients were significantly lower when compared to the values of control group. However, disulfide (19.4 ± 6.3 vs. 12.2 ± 6.3 μmol/L, p < 0.001) levels of FMS patients were significantly higher than healthy individuals. A negative correlation was found between the native thiol/total thiol and fibromyalgia impact questionnaire (FIQ) score among the FMS patients. A positive correlation was found between disulfide values and FIQ score among the patients. Conclusions: In FMS patients, there was a significant correlation between the decrease in the thiol levels and an increase in the disulfide levels with the FIQ scores. We determined that thiol-disulfide rate was deteriorated in FMS patients and it increases in favor of disulfide amounts.

Spinal epidermoid cysts are benign tumors. Syringomyelia secondary to intramedullary tumors are frequently observed. However, the association between syringomyelia and spinal intradural extramedullary epidermoid cyst in the conus medullaris region is extremely rare. We present the case of a 3-year-old male who was admitted with paraparesis and urinary retention. Magnetic resonance imaging (MRI) of the spine demonstrated intradural extramedullary lesion, compatible with epidermoid cyst, that at the conus medullaris level and a large syringomyelia extending from T4 to L1 vertebrae. Total microsurgical excision of the cyst was performed. No additional drainage was carried out for the syringomyelic cavity. Histopathological examination verified the diagnosis of the epidermoid cyst. Total excision of the cyst and disappearance of the syringomyelia were observed on MRI at 15 days postoperatively. We have clarified the etiology, clinical, histopathological and radiological features, differential diagnosis, and treatment modalities of spinal epidermoid cysts. In addition, we have discussed the possible mechanisms of syringomyelia formation in spinal intradural lesions.

In this study the effects of zinc sulfate and gibberellin on agro physiological of white bean under water deficiency were studied. Therefore, an experiment was conducted in a split-split plot design based on a randomized complete block with three replications in two places. The experimental factors included three irrigation levels, spraying of zinc sulfate in four levels and two levels of non-spraying and spraying of gibberellin. Analysis of measured data indicated that the water stress had a significant effect on all traits, except proline amount and 100 seeds weight. Spraying of zinc sulfate showed a significant effect on all traits except carotenoid value. Application of gibberellin had a significant effect on all traits except ion leakage, carotenoids, number of seeds per pod and grain yield. The interaction effect of stressí—zincsulfateí—gibberellin was significant on all traits except number of seeds per pod. In addition, comparison of means at 5% level, showed that application of 1.5 ml L-1of zinc sulfate plus gibberellin improved bean biochemical properties. Under optimum water level, using of 4.5 ml L-1of zinc sulfate and under severe water stress conditions, using of 4.5 ml L-1 of zinc sulfate plus gibberellin are recommended for obtaining the maximum crop performance.

The plateau zokor (Myospalaxbaileyi) is a specialized subterranean rodent that lives on the Qinghai-Tibet Plateau, and has successfully adapted to hypoxic environment. Raised expression of vascular endothelial growth factor (VEGF) and enhanced microvessel density (MVD) in tissues enable subterranean rodents to adapt to hypoxic sealed burrows. However, the expression of VEGF is inhibited by decreases in oxygen content, which is different from what obtains in Sprague Dawley (SD)rats. Thromspondin-1(TSP-1) is the first endogenous angiogenesis inhibitor identified inp53 pathway. It has several domains that bind to different proteins which regulate cell-to-cell interactions, inhibit endothelial cell proliferation and induce endothelial cell apoptosis (anti-angiogenesis). In this study, we analyzed the coding region and the expression pattern of TSP-1 gene in plateau zokor under different oxygen partial pressures using bioinformatics and qRT-PCR, respectively. Our results showed that the base and amino acid homologies between plateau zokor and Northern Israeli blind subterranean mole rat (Nannospalaxgalili) were 95.08 and 97.61%, respectively. There were eight parallel evolution sites with Nannospalaxgalili. Evaluation by ‘Sorting Tolerant From Intolerant' (SIFT) algorithm showed four sites with significant effects on the function of TSP-1. Three-dimensional (3D) structures revealed that Asp185 and Thr270 were located in the NH2 terminal domain, with Glu536 in the Type I repeat domain, and Thr1092 in the COOH terminal domain. Compared to SD rats, the polarities of these four mutation sites changed. The expression levels of TSP-1 in plateau zokor tissues increased significantly from 2 260 m(16.12kPa) to 3 300 m(14.13kPa), but there was no significant difference in TSP-1 expression in SD rats. In conclusion, due to long-term adaption to the hypoxic environment of sealed burrows, plateau zokor upregulates the expression of TSP-1 to effect anti-angiogenesis. Moreover, mutations in gene structure of TSP-1 may play an important role in inhibiting angiogenesis.

Published: April 2019

A "signomial" is a mathematical function, contains one or more independent variables. Richard J. Duffin and Elmor L. Peterson introduced the term "signomial". Signomial geometric programming (SGP) optimization technique often provides a much better mathematical result of real-world nonlinear optimization problems. In this research paper, we have proposed unconstrained and constrained signomial geometric programming (SGP) problem with positive or negative integral degree of difficulty. Here a modified form of signomial geometric programming (MSGP) has been developed and some theorems have been derived. Finally, these are illustrated by proper examples and applications.

“Unfortunately the new element for the examination of which he came over, proves shy and will not disclose itself. I cannot imagine what it can be, and seriously doubt its existence. This is disappointing and leaves one more gap in the list of the known elements."

Uranium deposits are crucial resources for the development of the nuclear energy. Among known sources of uranium, the uranium-rich shales have recently obtained significance. In this paper, the Lower Cambrian Wangyinpu Formation shale in the Xiuwu Basin, southern China, has been studied using a combination of techniques including element analysis (Al, Fe, and Mn), δ30Si silicon isotopic analysis, δ18O oxygen isotopic analysis, study of core samples. It has been observed that significant hydrothermal activity occurred in the Xiuwu Basin during the Early Cambrian period. The results show that 20%–40% of the silicon in most of the sections of the Lower Cambrian Wangyinpu Formation were inherited from the hydrothermal fluids, with temperatures ranging between 75∘C and 102∘C. It is concluded that more than 90% of the uranium in most of the sections of the Lower Cambrian Wangyinpu shale was derived from submarine hydrothermal fluids, while less than 10% from the terrigenous detritus. The enrichment of uranium in the basin was observed in the Middle-Upper part of the Wangyinpu Formation and the geological resources estimated to a tune of ~4.9×103 t. In this paper, we proposed a model for silicon and uranium enrichment in the Lower Cambrian shale controlled by hydrothermal activity in the Xiuwu Basin. This model also provides a scientific rationale for uranium further exploration and exploitation of the uranium resource.
