The death of a medieval Danish warrior. A case of bone trauma interpretation
Authors: Forsom Eva , Boel Lene Warner Thorup , Jaque Bo , Mollerup Lene
Published: March 2017

In 1934 a grave was found in the church ruins of the Cistercian Abbey at Øm in central Jutland, Denmark (founded in 1172, demolished 1561 AD). The grave contained the skeletal remains of an individual lying in a supine position with the head towards the west. The anthropological analysis revealed that the remains belonged to a young male, aged 25-30 years at death and approximately 162.7 cm tall. He had 9 perimortem sharp force lesions, five of which were cranial and four were postcranial, indicating he suffered a violent death in a swordfight.

This paper presents a detailed analysis and description of the individual lesions and their probable effect on the soft tissue, followed by a suggestion for the most likely order of the blows which caused the lesions, and finally a tentative reconstruction of the battle accompanied by photographs. This case illustrates both that forensic pathology can be very useful when applied to an archaeological case and suggests that the forensic pathologist could benefit from examination of ancient cases when interpreting bone lesions in modern cases.
Childhood Maltreatment as Predictor of Pathological Personality Traits Using PSY-5 in an Adult Psychiatric Sample
Authors: Choi Ji Young , Park Soo Hyun
Published: March 2017

Extant literature indicates that childhood maltreatment is significantly associated with personality disorders. With the recent call for a more dimensional approach to understanding personality and pathological personality traits, the aim of the present study was to examine whether the experience of childhood maltreatment is associated with pathological personality traits as measured by the Personality Psychopathology Five (PSY-5). We analyzed data from 557 adult psychiatric patients with diverse psychiatric diagnoses, including mood disorders, schizophrenia spectrum disorders, and anxiety disorders. Hierarchical multiple regression analyses were conducted to determine the degree to which childhood maltreatment explained the five trait dimensions after controlling for demographic variables, presence of psychotic symptoms, and degree of depressive symptoms. Childhood maltreatment significantly predicted all of the five trait dimensions of the PSY-5. This suggests that childhood maltreatment may negatively affect the development of an adaptive adjustment system, thereby potentially contributing to the emergence of pathological personality traits.
Maltreatment Risk Among Children With Disabilities
Authors: Maclean Miriam J. , Sims Scott , Bower Carol , Leonard Helen , Stanley Fiona J. , O’Donnell Melissa
Published: March 2017

BACKGROUND:

Children with disabilities are at increased risk of child maltreatment; however, there is a gap in the evidence about whether all disabilities are at equal risk and whether risk factors vary according to the type of disability.

METHODS:

A population-based record-linkage study of all children born in Western Australia between 1990 and 2010. Children with disabilities were identified by using population-based registers and risk of maltreatment determined by allegations reported to the Department for Child Protection and Family Support.

RESULTS:

Although children with disabilities make up 10.4% of the population, they represent 25.9% of children with a maltreatment allegation and 29.0% of those with a substantiated allegation; however, increased risk of maltreatment was not consistent across all disability types. Children with intellectual disability, mental/behavioral problems, and conduct disorder continued to have increased risk of an allegation and substantiated allegation after adjusting for child, family, and neighborhood risk factors. In contrast, adjusting for these factors resulted in children with autism having a lower risk, and children with Down syndrome and birth defects/cerebral palsy having the same risk as children without disability.

CONCLUSIONS:

The prevalence of disabilities in the child protection system suggests a need for awareness of the scope of issues faced by these children and the need for interagency collaboration to ensure children’s complex needs are met. Supports are needed for families with children with disabilities to assist in meeting the child’s health and developmental needs, but also to support the parents in managing the often more complex parenting environment.
Effect of primycin on growth-arrested cultures and cell integrity of Staphylococcus aureus
Authors: Feiszt Péter , Schneider György , Emődy Levente
Published: March 2017

Bactericidal effect against non-dividing bacteria is a very advantageous, but rare characteristic among antimicrobial agents, mostly possessed by those affecting the cell membrane. These kinds of agents can kill bacterial cells without lysis. We assessed these characteristics on primycin, a topical anti-staphylococcal agent highly effective against prevalent multiresistant strains, as it also acts on the cell membrane. In time-kill studies, primycin preserved its bactericidal activity against growth-arrested Staphylococcus aureus cultures. The bactericidal action was slower against growth-arrested cultures compared to the exponentially growing ones to different extents depending on the manner of arrest. The bactericidal effect was less influenced by stringent response and by protein synthesis inhibition, proving that it does not depend on metabolic activity. In contrast, uncoupling of the membrane potential predominantly slowed, and low temperature almost stopped killing of bacteria. In consideration of published data, these facts suggest that the antibacterial action of primycin involves disrupting of the membrane potential, and is predominantly influenced by the membrane fluidity. Optical density measurements and transmission electron microscopy verified that primycin kills bacterial cells without lysis. These results reveal favorable characteristics of primycin and point to, and broaden the knowledge on its membrane-targeted effect.

Published: March 2017

Yeast protein sequence-based homology search for glutathione (GSH) metabolic enzymes and GSH transporters demonstrated that Aspergillus nidulans has a robust GSH uptake and metabolic system with several paralogous genes. In wet laboratory experiments, two key genes of GSH metabolism, gcsA, and glrA, encoding γ-l-glutamyl-l-cysteine synthetase and glutathione reductase, respectively, were deleted. The gene gcsA was essential, and the ΔgcsA mutant required GSH supplementation at considerably higher concentration than the Saccharomyces cerevisiae gsh1 mutant (8–10 mmol l−1 vs. 0.5 μmol l−1). In addition to some functions known previously, both genes were important in the germination of conidiospores, and both gene deletion strains required the addition of extra GSH to reach wild-type germination rates in liquid cultures. Nevertheless, the supplementation of cultures with 10 mmol l−1 GSH was toxic for the control and ΔglrA strains especially during vegetative growth, which should be considered in future development of high GSH-producer fungal strains. Importantly, the ΔglrA strain was characterized by increased sensitivity toward a wide spectrum of osmotic, cell wall integrity and antimycotic stress conditions in addition to previously reported temperature and oxidative stress sensitivities. These novel phenotypes underline the distinguished functions of GSH and GSH metabolic enzymes in the stress responses of fungi.

Published: March 2017

Potimirim potimirim (Müller, 1881), a species of coastal freshwater shrimp, is recorded for the first time from the state of Rio Grande do Norte, northeastern of Brazil, where it was collected in a small tributary of the Potengi River. This record extends the distribution of this species about 220 km north along Brazilian coast. New records, such as this, reinforce the need for greater research efforts in the northeastern freshwater ecosystems of Brazil to provide better understand the region’s biodiversity and establish better parameters for conservation actions.
Lower third molar fused with a supernumerary tooth: diagnosis and treatment planning using Cone-Beam Computed Tomography
Authors: FERREIRA-JÚNIOR Osny , ÁVILA Luciana Dorigatti de , SAMPIERI Marcelo Bonifácio da Silva , DIAS-RIBEIRO Eduardo
Published: March 2017

Fusion is the union of two developing dental germs, resulting in a single large dental structure. It involve two normal dental germs or the germ of a normal tooth with a germ of a supernumerary one. Supernumerary teeth are additional teeth of the normal series which may occur in any region of the dental arch, althoug they are more common in the maxilla than in the mandible. This article presents a case of fusion between a third molar and a supernumerary tooth, in which a surgical intervention was carried out, with the objective of removing the dental elements. The panoramic radiography was complemented by the Donovan´s radiographic technique, but because of the proximity of the dental element to the mandibular ramus, it was not possible to have a final fusion diagnosis. Hence, the Cone-Beam Computed Tomography which provides precise three-dimensional information, was used to determinate the fusion diagnosis and also to help in the surgical planning.

The article also aims to compare the data with other available sources, such as tax sources, as well as to assess the validity of the proposed estimates.
Simulation of uncertainties in shrinkage and creep effects in concrete
Authors: Tang Hongyuan , Wang Ruijiao , Peng Chunmei
Published: March 2017

This paper addresses the simulation of uncertainties in shrinkage and creep effects in concrete structures. Extant models of shrinkage and creep are summarized and compared, such as the CEB-FIP 90 model, the ACI 209-92 model, the B3 model, the BP-KX model and the BP model. The statistical properties, mean value and coefficient variation, of every basic variables related to the cited models are presented, as well as that of models. Because there are too many factors influencing the properties of the shrinkage and the creep in concrete, the Latin hypercube sampling (LHS) is introduced as a method for simulating the uncertainties of these time effects in concrete. Given the properties of concrete and the ambient environment, the uncertainties of shrinkage and creep effects are simulated using LHS. Results indicate that the Comité Euro-International du Béton and American Concrete Institute models provide the best predictions of uncertainties of concrete shrinkage and creep, respectively.
Experiência, percepção e espaço urbano: convivência e ocupação ressignificando o habitar na cidade
Authors: Wachholz Chalissa Beatriz , Comunello Luciele Nardi
Published: March 2017

O presente artigo busca compreender, através das contribuições da educação ambiental e da psicologia ambiental, bem como de conceitos de experiência e percepção na fenomenologia de Merleau-Ponty, os efeitos da ocupação do espaço urbano através de dois eventos realizados nos principais parques da cidade de Porto Alegre-RS: o “Pique-nique Noturno”, realizado nos parques Farroupilha e Moinhos de Vento e o Festival de Comida de Rua, realizado em bairros centrais da cidade. Estes dois eventos assemelham-se por aproximar a alta gastronomia dos espaços públicos, possuem caráter filantrópico, pois promovem doações dos participantes para entidades assistenciais e se apresentam como espaços potenciais para uma experiência acerca do espaço urbano e da convivência de humanos entre si e com o ambiente urbano. Entendemos que a possibilidade de uma experiência nesse contexto pode contribuir para modificar a percepção das pessoas acerca do habitar a cidade e da relação que estabelecem entre si e com o ambiente em que estão inseridas.
Da colonização à agência dos atores: a implementação de políticas públicas por organizações civis
Authors: Tirelli Cláudia
Published: March 2017

O artigo discute as diferentes apropriações de uma política pública – Programa Rede Parceria Social – pelas organizações civis que atuam na área da Assistência Social no Rio Grande do Sul, através da realização de dois estudos de caso nos anos de 2011 e 2012. A partir de uma perspectiva teórica assentada na sociologia relacional e no institucionalismo histórico, analisa-se de que forma a trajetória institucional dos atores sociais, a qual os levou a ocupar no presente determinadas posições (relacionais) no campo da Assistência, condiciona a sua forma de interpretar se apropriar de oportunidades políticas como a representada pelo Programa Rede Parceria Social. Nesse sentido, coloca-se sob suspeição as teses proferidas pelas Ciências Sociais brasileiras que apontam para processos generalizados de “colonização” das organizações da sociedade civil pelo mercado ou da sua “hegemonização” por um projeto político neoliberal. Neste artigo parte-se da premissa de que a forma através da qual as organizações irão se relacionar com as oportunidades políticas, em determinada conjuntura, é algo a ser verificado por intermédio de investigações empíricas e, portanto, não pode ser respondido através de inferências causais que respondem a priori sobre a intencionalidade dos agentes e sobre os resultados de suas ações.

Authors: Kulygina Yu A , Osipenko M F , Skalinskaya M I , Palchunova K D
Published: March 2017

Aim. To assess the prevalence of bacterial overgrowth syndrome (BOS) and its risk factors in patients with inflammatory bowel diseases (IBD). Subjects and methods. The patients from the Novosibirsk IBD registry, who had undergone a hydrogen breath test (HBT) using a Gastro+ device, were examined. Results. In 93 IBD patients who had undergone a HBD, the prevalence of BOS was 48% (46.2% for ulcerative colitis and 51.2% for Crohn’s disease). There was a strong correlation between abdominal bloating, abdominal rumbling, and positive HBT results in both patient groups. During the HBT, the patients with BOS frequently complained of diarrhea, borborygmi, belching, and anxiety. Conclusion. The findings suggest that BOS is highly prevalent among patients with IBD. BOS is associated with clinical symptoms, such as abdominal bloating, abdominal rumbling, tearfulness, and irritability.

Published: March 2017

Aim. To study the spectrum of serum fatty acids (SSFA) and the composition of blood lipids in cholelithiasis (CL) in various ethnic groups of East Siberia. Subjects and methods. A clinical and epidemiological study was conducted, during which ultrasonography and oral cholecystography were used to examine 991 Khakases and 934 Europoids in Khakassia and 652 Evenks and 996 Europoids in Evenkia. Biochemical tests were performed to determine serum lipids in 20% of the random sample. Gas liquid chromatography was applied to investigate ASSFA in 220 patients in Khakassia and 157 people in Evenkia. Results. The manifestations of hyperlipidemia were detected in the Europoids with CL in Evenkia and Khakassia. These changes were less pronounced in the Evenks with CL and absent in the Khakases with CL. In all populations, the blood levels of saturated FAs and ratios of saturated to unsaturated FAs were considerably higher in the patients with CL than in the healthy individuals. Conclusion. The higher levels of saturated FAs and the lower proportion of serum unsaturated FAs are a universal marker of lipid metabolic disturbances in patients with CL in genetically different populations.

Aim. To estimate the incidence of abdominal pain syndrome (APS) and to assess quality of life (QOL) in patients within 10 years after cholecystectomy (CE). Subjects and methods. This investigation is part of a long-term prospective follow-up study of patients after CE for cholelithiasis (CL). It enrolled 145 people: 30 (21.5%) patients with baseline asymptomatic CL and 115 (80.7%) with its clinical manifestations. The time course of changes in APS and QOL were analyzed. Results. Over 10 years, all the patients showed a decrease in the incidence of APS from 84.1% (n=95) to 66.4% (n=75; p=0.004). In Group 1 (n=89), APS was at baseline detected in all the patients; 10 years later, its incidence declined to 67.4% (n=60; p < 0.001). Biliary pains were predominant; these had been identified significantly less frequently over the 10-year period in 47 (52.8%) patients; p
Possibilities for optimization of eradication therapy for Helicobacter pylori infection in modern clinical practice
Authors: Andreev D N , Dicheva D T , Maev I V
Published: March 2017

A steady decline in the effectiveness of standard eradication therapy (ET) regimens for Helicobacter pylori infection necessitates a search for ways of their optimization, by enhancing the efficiency of treatment protocols and by improving their safety and tolerability. The review systematizes the data available in the literature on main accessible methods for optimizing ET regimens. Among the optimization methods that can considerably enhance the efficiency of ET regimens, one may identify their addition of a bismuth agent (by 10—20%), the use of rebamipide (by 11.9%), adjuvant therapy with probiotics (by 8.1—13%), or double-dose proton pump inhibitors (by 8%). Only adjuvant therapy with probiotics results in a significant decrease in the incidence of side effects from ET. In posteradication period, rebamipide should be used to potentiate gastric mucosal repair and to regress inflammatory processes.
O lugar nos estudos toponímicos: reflexões
Authors: Andrade Karylleila Santos
Published: March 2017

Resumo: Este texto parte da seguinte questão norteadora: qual é a posição ou status que lugar ocupa nos estudos toponímicos? O objetivo geral é discutir lugar como categoria na disciplina toponímia para, em seguida, propor seu alargamento conceptual. Utilizar-se-á a abordagem teórica da Geografia Cultural e Humanista, a partir do viés da Fenomenologia, como também, os princípios teórico-metodológicos da disciplina Toponímia. É uma pesquisa de cunho qualitativa e interpretativista. Conclui-se, nesta etapa do trabalho, que lugar pode ser interpretado como categoria, pois trata-se da extensão/apreensão das relações (motivações) as quais são estabelecidas entre o homem e o próprio nome de lugar: é a sua gênese. O alçamento, enquanto categoria central, deu-se com uma discussão prévia das categorias espaço, território, paisagem e lugar. Daí o conceito em uma dimensão analítica: motivacional, histórica, linguística, ideológica, social, identitária. Quanto à sua extensão semântica, essa acontece no plano da abstração do vínculo que se estabelece entre o denominador e o designatum: como sentimento de pertencimento, afetividade, mundo vivido e experienciado.Palavras-chave: lugar; categoria; toponímia; geografia cultural e humanista.Abstract: This paper stems from the following guiding question: what is the position or status that place occupies in toponymic studies? The overall objective is to discuss place as a category in toponymic studies and, then, to propose an extension for its concept. We will use the theoretical approach of Cultural and Humanistic Geography, from the the point of view of Phenomenology, and also the theoretical and methodological principles of Toponymy as a discipline. It is a research of qualitative and interpretative nature. It can be concluded, at this stage of the work, that place can be interpreted as a category because it is the extension/seizure of relations (motivation) that are established between man and the place name itself: it is its genesis. Its rising, as a nuclear category, was achieved after prior discussion of space, territory, landscape and place categories. Hence the concept in an analytical dimension: motivational, historical, linguistic, ideological, social, identitary. As for its semantic extension, this happens in the abstraction plan of the bond that is established between the denominator and the designatum: as sense of belonging, affection, world lived and experienced.Keywords: place; category; toponymy; cultural and humanistic geography.
A semiótica das paixões e a análise da dimensão passional dos enunciados
Authors: Lima Eliane Soares de
Published: March 2017

Resumo: Adotando uma perspectiva diacrônica, a intenção deste artigo é a de apresentar os desenvolvimentos teóricos e metodológicos que têm marcado o estudo das paixões dentro do quadro geral da semiótica de linha francesa. Interessa a partir daí retomar os apontamentos que assinalaram a chamada “virada fenomenológica” da teoria – enquanto momento no qual a preocupação com o sensível, com as condições de emergência do sentido, passa a ocupar o centro da atenção dos semioticistas – e discutir os desafios impostos, a necessidade de contínua evolução do modelo de análise criado para dar conta desse outro universo de significação. Assim, com base nos desdobramentos mais recentes da teoria, agora voltados à problemática da enunciação, do sentido configurado em ato, propõe-se uma reformulação do esquema passional canônico tal como concebido no livro Semiótica das paixões, de Greimas e Fontanille.Palavras-chave: semiótica; paixões; dimensão passional; modalidades; tensividade. Abstract: Adopting a diachronic perspective, the aim of this article is to present the theoretical and methodological developments that have characterized the study of passions within the general framework of French Semiotics. From this perspective, we’d like to go back to the writings which have marked the so-called “phenomenological turn” of the theory – as the moment when the concern with the sensitive, with the conditions of meaning emergence, becomes a major issue for semioticians – and discuss the challenges inflicted, the need of a constant evolution on the pattern of analysis created in order to examine this alternative universe of signification. Thus, based on the theory’s most recent developments, having to do with enunciation, with meaning set up in act, we propose a reorganization of the canonical pathemic schema as featured in Greimas and Fontanille’s Sémiotique des passions.Keywords: semiotics; passions; emotional dimension; modality; tensivity.
A comparative evaluation of analgesic and anti-inflammatory activities of two medicinal plants rubia cordifolia and cassia fistula in wistar albino rats
Authors: Y. R. Rajashekar , K. M. Narasimhamurthy
Published: March 2017

Background: Pain and inflammation are disabling accompaniments of many medical conditions. So, controlling both pain and inflammation assumes the top priority for the physician. Inflammation is a part of a complex biological response of vascular tissues to harmful stimuli such as pathogens, chemicals or irritants. Therapy of pain and inflammation has always been debatable.Methods: Rats were divided into 8 groups of 6 animals of each. The anti-inflammatory activity was studied with carrageenan induced rat paw edema and cotton pellet induced granuloma models. The analgesic activity was evaluated using Eddy’s hot plate model. The aqueous extract of Rubia cardifolia root and Cassia fistula leaf preparations were compared with Diclofenac in both acute and sub acute inflammatory models and also in pain model.Results: Various test result parameters were statistically analysed at P value <0.5. In Eddy's hot plate model both RC and CF preparations prolonged the response reaction time, while CF preparation showed longer reaction time than that of RC preparation. In carrageenan induced paw edema and cotton pellet induced granuloma models, both RC and CF preparations showed significant decrease in paw edema volume and granuloma dry weight respectively, but less than that of Diclofenac. RC preparation found to have dose dependant in inflammatory models.Conclusions: RC root and CF leaf preparations were compared head to head and they have been found to have significant dose dependant analgesic activity and dose independent acute and sub acute anti inflammatory activities. Though CF leaf preparation appeared to be a good analgesic than RF root preparation, but failed to do so as an anti inflammatory agent in both inflammatory models. But both test preparations were not equivalent to Diclofenac in all three models.

Intrathoracic fat volume, more specifically, epicardial fat volume, is an emerging imaging biomarker of adverse cardiovascular events. The purpose of this work is to show the feasibility and reproducibility of intrathoracic fat volume measurement applied to contrast-enhanced multidetector computed tomography images. A retrospective cohort study of 62 subjects free of cardiovascular disease (55% females, age = 49 ± 11 years) conducted from 2008 to 2011 formed the study group. Intrathoracic fat volume was defined as all fat voxels measuring −50 to −250 Hounsfield Unit within the intrathoracic cavity from the level of the pulmonary artery bifurcation to the heart apex. The intrathoracic fat was separated into epicardial and extrapericardial fat by tracing the pericardium. The measurements were obtained by 2 readers and compared for interrater reproducibility. The fat volume measurements for the study group were 141 ± 72 cm3 for intrathoracic fat, 58 ± 27 cm3 for epicardial fat, and 84 ± 50 cm3 for extrapericardial fat. There was no statistically significant difference in intrathoracic fat volume measurements between the 2 readers, with correlation coefficients of 0.88 (P = .55) for intrathoracic fat volume and −0.12 (P = .33) for epicardial fat volume. Voxel-based measurement of intrathoracic fat, including the separation into epicardial and extrapericardial fat, is feasible and highly reproducible from multidetector computed tomography scans.

Resumo: Neste trabalho analisamos os artigos publicados entre 2005 a 2011 no GT de Didática, da ANPEd. Os objetivos são: a) captar as bases epistemológicas que fundamentam as discussões dos pesquisadores no âmbito do ensino e da aprendizagem de Ciências; e b) provocar o pensamento para as possíveis linhas de fuga de um ensino de Ciências pautado na convivência com o caos e a diferença. Metodologicamente a análise foi pautada na filosofia da diferença a partir das teorias de Deleuze e Guattari e propõe um breve exercício de desconstrução/problematização dos alicerces do pensamento moderno aplicados à educação e que aparecem nesses artigos. O resultado demonstra como as teorias que subsidiam os artigos estão atreladas ao pensamento da representação e que a Didática para/no ensino de Ciências produz um aligeiramento ao confundir ou precipitar a criação de “metodologias” de ensino a partir das proposições teórico-científicas oriundas da psicologia e da sociologia.  Palavras- Chave: Ensino de Ciências.

Aboriginal Language and School Outcomes: Investigating the Associations for Young Adults
Authors: Guevremont Anne , Kohen Dafna
Published: March 2017

Being taught an Aboriginal language at school has generally been associated with positive school outcomes for Aboriginal children but not adults. This study attempted to understand this discordance by examining three possible explanations: (a) confounding variables, (b) a cohort effect, and (c) differences in the timing and duration of Aboriginal language instruction. Confounding variables (school attendance on reserve, parental education, and family residential school attendance) and duration of Aboriginal language instruction (six of more grades) were important contributors; whereas the presence of a cohort effect and the timing of Aboriginal language instruction were not found to be significant. Future studies of Aboriginal language instruction should consider family educational experiences, location of schooling, and the duration of Aboriginal language instruction.
Performance of green gram - sesame mixed croppingin the red and lateritic zone of West Bengal
Authors: Moinuddin Golam
Published: March 2017

A field experiment was carried out in the red and lateritic soil of Regional Research Station, Jhargram, Bidhan Chandra Krishi Viswavidyalaya,West Bengal during the prekharif season of 2015 to evaluate the technological feasibility of mixed cropping of green gram with sesame under different seeding ratio. The experiment was conducted in a randomized block design with four replications. The treatments comprises for the experiment were T1-sole green gram, T2-sole sesame, T3-green gram: sesame -90:10, T4- green gram : sesame-75 : 25, T5- green gram : sesame-60 : 40 , T6 –green gram : sesame-50 : 50. Yield parameters like number branch/plant, number of pod/ plant, number of capsule/plant, pod length, number of grain per pod/capsule, grain weight etc. were studied. The highest grain yield for both crop was obtained from the sole cropping of green gram and sole sesame. The maximum land equivalent ratio(LER) of 1.18 was observed at green gram : sesame seeding ratio of 60 : 40.The highest green gram equivalent yield( 9.49 q/ha) was obtained from green gram : sesame seeding ratio of 60 : 40 . It was noticed that in all the mixed cropping systems, there was higher LER which indicates higher yield advantage over the sole crop.

Published: March 2017

The using of molecular marker is an efficient approach to analyze the genetic diversity and it can be used widely in biological studies. The characterization of rice germplasms  by using molecular markers is more precise because it is not influenced by environmental factors. The purpose of this study was to analyze the genetic diversity of 24 varieties of lowland and upland rice by using 15 SSR markers. The results showed as many as 86 alleles were detected in 24 rice varieties by using 15 SSR markers, with the average number of alleles per marker was 5,73 and the range of  alleles per locus was 2-10. The average of major allele frequency was 43% with the lowest score was 26% on RM6997 and RM536 markers and the highest score was 65% on RM60 marker. A total of 14 SSR markers were able to discriminate heterozygous alleles within a range between 0,17 (RM105) to 1,00 (RM201, RM263, RM416, RM518 and RM223). The value of gene diversity ranged from 0,48 (RM60) to 0,81 (RM536) with an average of 0,70. The value of PIC (Polymorphic Information Content) ranged from 0,38 (RM105) to 0,78 (RM536) with an average of 0,65. The phylogenetic analysis showed that 24 rice varieties separate into two main clusters in the coefficient of 0,63. The first cluster consists of 12 lowland varieties and the second cluster consists of 12 upland varieties. The genetic diversity  data  in this study were expected could be a valuable information in the rice plant breeding activities in the future.

Electrospinning is the versatile technique to generate large quantities of micro- or nano-fibers from a wide variety of shapes and sizes of polymer. Natural bone is a hierarchically composites with the dispersion of inorganic ceramic along organic polymer. The aim of this study, the electrospun poly (lactic acid) (PLA) mats coated with chitosan (CH) and calcium silicate (CS) powder were fabricated. The morphology, chemical composition, and surface properties of CS/CH-PLA composites were characterized by scanning electron microscopy, X-ray diffraction, and Fourier transform infrared spectroscopy. In vitro, the CS/CH-coated PLA mats increased the formation of apatite on the surface when soaking in cell cultured medium. During culture, the adhesion and proliferation of the human mesenchymal stem cells (hMSCs) cultured on CS/CH-PLA were significantly promoted relative to those on PLA. Collagen I and fibronectin levels and promoted cell adhesion were observed upon an increase in CS content. Further, compared to PLA mats without CS/CH, CS10 and CS15 mats markedly enhanced the proliferation of hMSCs as well as their osteogenesis properties, which was characterized by bone-related gene expression. Our results demonstrated that the biodegradable and electroactive CS/CH-PLA mats had potential application as an ideal candidate for bone tissue engineering. Together, findings from this study clearly demonstrated that PLLA-C2S composite scaffold may function as an ideal candidate for bone tissue engineering.

This paper presents a two-stage ADC based on pseudo-differential operational transconductance amplifier (OTA), which is designed for the readout circuit of X-ray linear array sensor. This hybrid ADC employs an incremental sigma-delta ADC and a cyclic ADC, achieving a good trade-off between accuracy and conversion speed. The two stages share the same hardware to reduce power consumption and die area. A common-mood feedback module is used to suppress the influence of charge injection, and the effectiveness is demonstrated by detailed theoretical analysis. A test chip of 14-bit ADC is fabricated in 0.35μm CMOS technology. The measured root mean square (RMS) value of DNL is 0.254 LSB, and the maximum value of INL is -0.776/+1.56 LSB. The measured effective number of bits (ENOB) is 13.43 bits.

A New Approach to the Modeling of Hydraulic-Fracturing Treatments in Naturally Fractured Reservoirs
Authors: Li Sanbai , Zhang Dongxiao , Li Xiang
Published: March 2017

A fully coupled thermal/hydromechanical (THM) model for hydraulic-fracturing treatments is developed in this study. In this model, the mixed finite-volume/finite-element method is used to solve the coupled system, in which the multipoint flux approximation L-method is used to calculate interelement fluid and heat flux. The Gu et al. (2011) crossing criterion is extended to a 3D scenario to delineate the crossing behaviors as hydraulic fractures meet inclined natural fractures. Moreover, the modified Barton et al. (1985) model proposed by Asadollahi et al. (2010) is used to estimate the fracture aperture and model the shear-dilation effect. After being (partially) verified by means of comparison with results from the literature, the developed model is used to investigate complex-fracture-network propagation in naturally fractured reservoirs. Numerical experiments show that the key factors controlling the complexity of the induced-fracture networks include stress anisotropy, injection rate, natural-fracture distribution (fracture-dip angle, strike angle, spacing, density, and length), fracture-filling properties (the degree of cementation and permeability), fracture-surface properties (cohesion and friction angle), and tensile strength of intact rock. It is found that the smaller the stress anisotropy and/or the lower the injection rate, the more complex the fracture network; a high rock tensile strength could increase the possibility of the occurrence of shear fractures; and under conditions of large permeability of fracture filling combined with small cohesive strength and friction coefficient, shear slip could become the dominant mechanism for generating complex-fracture networks. The model developed and the results presented can be used to understand the propagation of complex-fracture networks and aid in the design and optimization of hydraulic-fracturing treatments.

Published: March 2017

The goal of this work is to show what things generate more temperature than the simulation of downhole conditions, and how to mitigate them by, for example, selecting the appropriate ESP position, considering the production rates vs. zones, and the right materials for the production tubing in order to reduce motor operating temperature and increase run life.

This study recovers information from different sources, history data of 15 years of running electric submersible pumps in the field, detailed data over three years from three different electric submersible pump suppliers, and more than 80 tear down analysis.

Starting 2013, twenty-five (25) electric submersible pumps were run with high temperature down-hole sensors–the interpretation of that information was one of the keys to success. In three cases the setting depth of the equipment was changed to test the theory.

All the wells are in secondary recovery projects, so the injection rate and selective zone are very important to take into account.

Today there is no software that exists that can simulate, with accuracy, the real dynamic temperature of the ESP above or between zones.

Several flow simulations were run to prove the hypothesis, considering different flow rates and pump intake pressure.

The position of the ESP related to production zone, flow rate, and submergence will determine the dynamic temperature of the motor.

The use of special isolation tubing (VIT – Vacuum Insulated Tubing, for example) is one way to reduce the ESP temperature in the deeper and higher temperature wells.

The study of the temperature profile in a pump between zones is not a common situation in the oil industry, there is no literature that explores this kind of down-hole situation.

Today, there is no sizing/design software prepared to predict the temperatures in these types of installations. This paper will show the considerations required to do it properly.
Cementing Solution to Decrease Water Cut after Fracturing Operations

Unexpected waterflooding during production after fracturing can be a critical problem for newly completed wells. There are cases that reservoir evaluation has been properly done and water bearing zones identified, and the wells show high water cut after the completion. Typically near wellbore channeling or unwanted fracture height growth can cause such problem and a joint effort between cementing and fracturing may be a solution to reduce such risk to minimum.

Field-X is located in Jugger basin in western china. One of the major target oil zones is identified which is close to a water bearing formation in this field. There is evidence showing historically cementing bond was impaired because of the contamination from the formation water, which diverted the fracturing fluid from the perforated zones to the incompetent cement channels in the annulus. The result was a fracture geometry that deviated significantly from the design and waterflooding occurred when the water zone was connected.

A special cement slurry was formulated as a main solution to solve this problem. The cement's set-mechanical properties were tailored according to the pressure and temperature dynamics by a stress analysis simulator to ensure entire zonal isolation during the fracturing execution, and the slurry's waterproofing property was evaluated and verified in the laboratory by a series of special designed test procedures. Meanwhile, fracture design is completed with the consideration of height control, as lowered viscosity fluid and moderate pumping rate was employed for the completion.

The joint effort from cementing and fracturing design achieved positive results. Fifteen exploration wells from field-X has been successfully cemented with excellent bonding, and post fracturing treatment showed minimum water cut during flow back and production tests comparing to offset wells. The synergy between cementing and fracturing design proves its value for field-X as an effective measure to identify potential risks and provide solutions to similar scenarios, and it is believed to be valuable for hydrocarbon development in other complex areas.
The Simplified Pressure Test of Onshore Mature Fields in Sergipe-Alagoas Basin - Mathematical Model and Interpretation Procedure
Authors: Kubota L..
Published: March 2017

The leading type of transient pressure test in onshore fields of Sergipe-Alagoas Basin is the so-called Simplified Pressure Test (SPT). Its name stems from the fact it boasts an extremely lean downhole completion (a set of tubings and a production packer). Additionally, it does not require any flow measurement device. From an operational standpoint, all it takes is to settle the packer and let the downhole gauge record the pressure diffusion. It is as simple (and cheap) as that. Not surprisingly, the SPT has become the preferred well-testing choice for the financially-constrained onshore mature fields from Sergipe-Alagoas Basin.

In this paper, we write a mathematical model for the pressure diffusion taking place during a SPT and show that, by coupling Peres Integral Method and Gladfelter Approximate Deconvolution, wellbore storage effects can be successfully removed, unveiling the flow regime taking place within the porous medium. Moreover, we propose a pressure extrapolation technique to be employed when the SPT is performed on low-permeability reservoirs.

Field examples provide compelling evidence that, by following the outlined procedure, an operation as simple as the SPT can indeed provide reliable information at a relatively low cost.
