An upwind multistep difference-mixed volume element method for a positive semi-definite contamination treatment from nuclear waste
Authors: Li Changfeng , Yuan Yirang , Song Huailing
Published: August 2022

A three-dimensional contamination treatment problem from nuclear waste
in porous media, where the diffusion matrix is generally positive
semi-definite, is discussed in this paper. The mathematical model is
defined by a nonlinear initial-boundary system consisting of partial
different equations. An elliptic equation, two convection-diffusion
equations and a heat conductor equation are given to determine the
pressure, the concentrations of brine and radionuclide, and the
temperature, respectively. The concentration equations and heat
conductor equation include Darcy velocity dependent on the pressure, and
their physical motions are affected. A conservative mixed volume element
is used to approximate the pressure, and one-order computational
accuracy is improved for Darcy velocity. The concentrations of brine and
radionuclide and the temperature are solved by an upwind multiste
difference-mixed volume element, where the derivative to time is
approximated by a multistep difference, the diffusions and convection
terms are treated by a mixed volume element and an upwind approximation,
respectively. This composite method can eliminate numerical dispersion
and nonphysical oscillations, so it can solve convection-dominated
diffusion equations accurately and stably. The mixed volume element can
obtain the concentrations, temperature and their adjoint vectors
simultaneously, and it has the conservation of mass or energy. This
physical nature is important in numerical simulation of underground
fluid flow problems. Applying the theory and special treatment of a
priori estimates, we obtain optimal order estimates in L2-norm.
Numerical experiments show the efficiency and applicability in
simulating contamination treatment from nuclear waste.

Pharmacology of trace amine-induced vasodilatation: roles of endothelium and intracellular sites
Authors: Voisey Alex , Broadley Kenneth , Ford William
Published: August 2022

Abstract Background and Purposes: Although trace amines, including
β-phenylethylamine (β-PEA), cause vasoconstriction, they also induce
endothelial nitric oxide release via an unknown mechanism. This study
evaluates the cellular site of action and receptors mediating
β-PEA-induced vasodilation. Experimental Approach: In vitro vasodilator
responses to β-PEA were assessed using aortic rings and third-order
mesenteric arteries of male Sprague-Dawley rats. Key Results:
β-PEA-induced concentration-dependent vasodilation of pre-constricted
aortic rings and third-order mesenteric arteries were partially
sensitive and insensitive to endothelium removal, respectively. In
aortic rings vasodilator responses to β-PEA were unaffected by EPPTB, a
selective antagonist of murine trace amine associated receptor 1
(TAAR1), or antagonists of β2-adrenoceptors and muscarinic acetylcholine
M3 receptors. The inhibitor of uptake-2 transport, decynium-22,
abolished β-PEA-induced vasodilation revealing a vasoconstrictor
response. Conclusion and Implications: Vasodilator responses to β-PEA do
not involve cell surface receptors. We propose that β-PEA utilises
uptake-2 transporters to gain access to an intracellular site. Although
the identify of the intracellular site is unknown, the mechanism is
similar to that previously reported where intracellular TAAR1 medated
responses in HEK293 cells. Vasodilatation is the dominant response to
trace amines of mesenteric vessels whereas in the aorta, it opposes
vasoconstriction.
Flooding determines the assembly process of archaeal and bacterial communities in soil

Published: August 2022

Soil microbial communities play an essential role in riparian
ecosystems, which commonly consist of a few abundant taxa and numerous
rare taxa. However, relatively little is known about the community
assembly processes of abundant and rare taxa, and how these respond to
fluctuating environments. In this study, patterns and drivers of the
assembly processes for abundant and rare bacterial and archaeal
subcommunities in a riparian zone were determined. Results showed that
the community structures of abundant and rare bacteria and archaea
exhibited a consistent variation along the riparian elevation, which was
highly associated with flooding frequency. Rare taxa were
phylogenetically more closely clustered, but occupied narrower niche
breadths than abundant taxa. The community assembly of abundant and rare
bacteria was driven respectively by dispersal limitation and variable
selection; undominated processes and dispersal limitation dominated
abundant archaeal community, while rare archaea was primarily governed
by homogeneous selection. Soil moisture and ratio of time soil was
submerged to exposed to air were the two most decisive factors for the
assembly processes of both rare bacteria and abundant archaea. The
assembly processes of rare bacteria were also significantly associated
with soil NH4+, Fe2+ and Fe2+/Fe3+, while rare archaea were
significantly associated with C/N and total carbon. Here, flooding may
influence community assembly processes by shaping soil niches and
imposing disturbances. Overall, this study reveals divergent assembly
processes for abundant and rare subcommunities in the riparian zone,
which is essential knowledge to further elucidate the stability and
maintenance of ecosystem functions under changing environments.
Endocarditis at prior venous cannulation site after sternal wound infection: Case Report
Authors: Cappelli Jared , Edwards Amber
Published: August 2022

Endocarditis originating from a prior venous cannulation site  is
undescribed in the current literature. Infections of the heart pose
significant morbidity and mortality to patients, therefore prompt
recognition, diagnosis, and treatment are critical. Our patient
underwent coronary artery bypass grafting (CABG) and developed a
postoperative sternal wound infection with methicillin resistant
staphylococcus aureus (MRSA). After failing nonoperative management,
redo-sternotomy was performed with atrial wall debridement and patch
repair. During this procedure, two unexpected small discrete abscess
pockets of the right atrial epicardium were discovered. One of the
abscess pockets fistulized into the right atrium and was noted to be at
his prior venous cannulation site for cardiopulmonary bypass as
evidenced by neighboring prolene suture. The patient had an uneventful
recovery  and was discharged home on postoperative day 7. Transthoracic
echo was obtained 6 weeks after his second operation and did not show
any recurrence of endocarditis. We present a unique case of persistent
cardiac infection with a complicated course and management strategy.
Impact of the constrictions number on filtration characteristics of nonwoven geotextiles
Authors: Anna Markiewicz  , Eugeniusz Koda
Published: August 2022

The use of nonwoven geotextile filters is common in geoenvironmental and geotechnical engineering applications. The main requirements for successful performance of drainage and geotextile filters are soil retention, permeability and clogging resistance. In case of anti-clogging capabilities, the most popular method to evaluate the filtration behaviour of nonwoven geotextile in contact with soils is gradient ratio test. Also the number of constrictions of nonwoven geotextile should be determined on the basis of fibre diameter, thickness and porosity. The number of constrictions has been found to explain the different filtration behaviours of nonwoven geotextiles with similar or even the same opening sizes but different structures for various soil conditions. This paper presents the gradient ratio test program for internally unstable soil and nonwoven geotextiles with different structures. Test results show a significant impact of the number of constrictions on the filtration characteristics of geotextile. What is more some modifications to the filter design criteria are proposed based on interpretation of the experimental results.
Tolerance modelling of heat conduction in biperiodic fourth-component composite
Authors: Olga Szlachetka  , Joanna Witkowska-Dobrev
Published: August 2022

The object of analysis is a heat conduction problem within the framework of tolerance modelling in fourth-component biperiodic composite. Two materials are isotropic and two are orthotropic, and additionally symmetry axes of orthotropic ones are rotated with respect to each other by an angle equal 90°. The results of some special boundary conditions for stationary problem of heat conduction were obtained from the local homogenization model (LHM). The model equations were derived by simplifying the equations of the standard tolerance model (STM), which were obtained based on two model assumptions: micro-macro decomposition of the temperature field and residual function averaging, after introducing the concept of “weakly slowly varying function” (WSV) and “slowly varying function” (SV) into the modelling process. The presented examples show the influence of the given boundary conditions on the macro-temperature distribution and on the distribution of the approximate temperature field θ(). The effect of thermal conductivity of the component materials and the number of periodicity cells on temperature distribution was also shown.
Nomear o segredo: Uma leitura de Marighella, de Isa Grinspum Ferraz
Authors: Brum Liniane Haag
Published: August 2022

O artigo propõe uma leitura do documentário de longa-metragem Marighella (2011), em que defende que o eu encenado de Isa Grisnpum Ferraz - diretora, roteirista e narradora-locutora do filme - é fruto de uma auto-atribuição para testemunhar, tal como colocada por Shoshana Felman. Tem-se, assim, que não apenas a vida de Carlos Marighella é inventariada no documentário, mas, essencialmente, o testemunho de um segredo transmitido em infância é nomeado, depois de 40 anos. Uma aproximação com o método de análise fílmica de Sylvie Lindeperg, que propõe o resgate da historicidade da imagem de arquivo, serve como substrato analítico, o qual é conjugado com noção de anarquivamento depreendida de Walter Benjamin por Márcio Seligmann-Silva.
Retórica Neoliberal
Authors: Chauvin Jean Pierre
Published: August 2022

No século XX, a linguística, a estilística e, mais tarde, os estudos em torno da filosofia da linguagem propiciaram a sobrevivência da arte retórica e passaram a rediscutir seus usos, combinados a diversas áreas do saber. Neste artigo, resgatam-se algumas acepções da arte de persuasão, levando em consideração: 1. os sentidos vinculados ao termo, entre a Antiguidade grega e o século XVIII; 2. os usos dessa técnica, durante o século XIX; e o entrelugar da arte de persuadir a partir dos anos de 1930. Delimitado o termo, pretende-se problematizar o uso enviesado de conceitos como meritocracia, concorrência, liberdade e empreendedorismo – pilares do discurso neoliberal, que vigoram pelo menos desde a década de 1980. Um dos objetivos do ensaio é discutir o emprego do termo retórica com o sentido que ele passou a veicular em nosso tempo.
Grafia do pensamento: Carta ao pai, de Elida Tessler
Authors: Bosi Isabela
Published: August 2022

Neste artigo, nosso objetivo é refletir com e acerca do trabalho Carta ao pai (2015), da artista visual Elida Tessler, cujo pensamento artístico se constrói nas fronteiras entre literatura e artes visuais, imagem e palavra. Nessa obra, inspirada pelo livro homônimo de Franz Kafka (1952), a artista também se dirige ao próprio pai, mas em uma grafia sem alfabeto, que se constrói no e com o pensamento de que uma escrita também pode se dar de outros modos, por outros meios. Em diálogo com Roland Barthes, Maurice Blanchot, Jean-Luc Nancy, Giorgio Agamben, entre outros pensadores, analisamos a escrita de Tessler como uma carta fracassada, pura contingência, que nunca chegará ao destinatário, mas, dirigindo-se ao corpo-memória do pai, pode provocar uma abertura de sentidos, em um gesto poético de envio entre o limite e o impossível.
concretude das palavras e as formas materiais da memória em Amada, de Toni Morrison
Authors: Soares Marcos
Published: August 2022

Este ensaio traz uma análise do romance Amada (1987), da escritora estadunidense Toni Morrison, a partir da hipótese de que o ponto de fuga dos eventos do enredo é constituído por uma reflexão sobre o estatuto das palavras na sua relação com o registro das experiências dos escravos e seus descendentes. Longe de habitar um espaço de fluxo aberto ou liberdade discursiva, na sua lida com as palavras as personagens enfrentarão formas especificas de poder que ameaçam a manutenção de sua memória.  Desse ângulo, argumentaremos que o romance pode ser lido como uma discussão crítica sobre formas de sobrevivência de modos de sociabilidade pré-modernos no centro da vida contemporânea. Para isso, nos utilizaremos do conceito da “impossibilidade de narrar” que marcou parte central da discussão sobre a modernidade no trabalho de teóricos como Theodor Adorno e Walter Benjamin.

Economic Analysis and Policy Suggestions for Prenatal Screening and Diagnosis on Down's Syndrome in China
Authors: Hsieh Yi-jhan
Published: August 2022

Down Syndrome is a disease that can cause a significant economic burden on both society and individual families. It has a relatively high incidence compared to other conditions, but it can be detected with the proper use of prenatal screening and diagnostic tests. This paper conducted a cost-benefit analysis, cost-effectiveness analysis with the Incremental Cost-Effectiveness Ratio (ICER), a Criteria Importance through Intercriteria Correlation (CRITIC) model. Through using a Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) model to evaluate and compare the three different prenatal diagnostic tests for DS, amniocentesis, noninvasive prenatal testing (NIPT), and chorionic villus sampling (CVS). The result showed that amniocentesis and CVS are both cost-benefit and cost-effective, ranking the first in the CRITIC and TOPSIS models, with amniocentesis having a more significant lead. In contrast, NIPT has a negative net benefit and is not cost-effective, ranking third in both models. Amniocentesis should be compulsory in China, with the government covering $402 and individual families paying $98. Choices should be given to individual families if they are willing to pay more to take NIPT if they are worried about the risk of invasive amniocentesis. People with autoimmune diseases and other diseases that can increase the risk of miscarriage with an invasive test should be provided with NIPT with the government covering the extra fee. A selection system with the prenatal test for DS as the default choice is another option for policy implementation based on the nudge theory. This policy can release around $8,265,075,000 economic burden on the society and $1,100,000,000 on individual families annually in China, creating more economic value for the rapidly growing country.

Comparison of Modified RAZOR Curl and Nordic Hamstring Curl Exercises in improving Hamstring Muscle Performance among Male Volleyball Players
Authors:   PhD Scholar, Chettinad Academy of Research Education, Tamil Nadu, India., Muralidharan CK
Published: August 2022

Background: Volleyball players’ lower extremity strength, power, and flexibility are more significant, and hamstrings, in particular, affect their performance. Concentric hamstring performance-enhancing methods are the most common. They may reduce hamstring flexibility and raise the risk of strain. In this study, we focused on enhancing hamstring muscle performance in volleyball players using particular hamstring eccentric training regimens that increase lower extremity performance.Method: A total of 40 volleyball players were sorted into two groups using a suitable sampling procedure based on inclusion and exclusion criteria. For 12 weeks, Group A (n = 20) received modified RAZOR curl while Group B (n = 20) received Nordic hamstring curl.Results: The mean values for the 1 Repetition Maximum and 40 Yard Dash Tests were 11.6 and 1.24, respectively, with standard deviations of 1.63 and 0.31, and paired ‘t’ values of 12.86 and 3.26, indicating that Group B (Nordic hamstring curl) showed substantial gains in strength and power. However, Group A (modified RAZOR curl) improved significantly in the Superman Exercise Test from baseline, with a mean of 12.1 and a standard deviation of 1.74. In the 1 Repetition Maximum, 40 Yard Dash Test, and Superman Exercise Test, both groups had unpaired ‘t’ values of 12.86, 3.26, and 16.69.Conclusion: Both groups improved in strength and power, according to the findings of this study. Although Group B trained volleyball players improved more, modified RAZOR curl (Group A) was more pertinent to be used for functional training and increased activation of supporting muscles, especially the core muscles.

Role of Proton Pump Inhibitor in the Management of Acid-Related Disorders
Authors: Arsita Elli , Fauzi Achmad
Published: August 2022

Proton pump inhibitor (PPI) is the strongest inhibitor to gastric acid secretion. PPI is effective in all gastricacid disorders, such as: peptic ulcer, gastroesofageal reflux disease, non steroid anti inflammatory drugs (NSAIDs)gastropathy, and Zollinger-Ellison syndrome. Several studies comparing one PPI to another. Although somedifferences have been reported, there are small differences with unclear clinical importance.PPI has side effects that may be related to diarrhea due to Clostridium difficile, pneumonia, hip fracture, vitamin B12 deficiency, and IgE mediated allergic reaction. Several studies revealed strong association but havelimitation in design and sampel size. PPI therapy should be according to indication, dose, and appropriate period.Keywords: proton pump inhibitor, gastric acid disorder, indication, dose, period ABSTRAKPenghambat pompa proton (PPP) adalah inhibitor paling kuat terhadap sekresi asam lambung. PPPefektif untuk terapi semua gangguan asam lambung termasuk ulkus peptikum, penyakit gastroesofageal reflux,gastropati karena obat anti inflamasi non steroid (OAINS), dan sindrom Zollinger-Ellison. Beberapa penelitianmembandingkan beragam PPP satu dengan yang lainnya. Walaupun dilaporkan ada beberapa perbedaan,namun besaran perbedaannya kecil dan tidak jelas kepentingan klinisnya.PPP kemungkinan berkaitan dengan efek samping diare karena Clostridium difficile, pneumonia, frakturpanggul, defisiensi vitamin B12, dan reaksi alergi yang dimediasi IgE. Beberapa penelitian menunjukkanhubungan yang kuat namun memiliki keterbatasan desain dan besaran sampel. Terapi PPP harus sesuai denganindikasi, dosis, dan jangka waktu yang tepat.Kata kunci: penghambat pompa proton, gangguan asam lambung, indikasi, dosis, jangka waktu

Cholangiocarcinoma is the second most common primary liver malignancy with a global increase ofincidence and mortality. The mean age at presentation is 50 years. Patients with cholangiocarcinoma usuallywill have symptoms of obstructive jaundice followed with supporting laboratory and imaging findings. Thepredominant clinical feature of extrahepatic cholangiocarcinoma is biliary obstruction resulting in jaundice; while intrahepatic cholangiocarcinoma causes symptoms of intrahepatic mass including abdominal pain in right upper quadrant and other tumor-related symptoms such as cachexia and malaise. The diagnosis and stagingof cholangiocarcinoma require multidisciplinary approaches including laboratory, radiological, endoscopicapproaches and analysis on pathology. This case report describes a patient with a cholangiocarcinoma based on results of endoscopic retrogradecholangiopancreatography (ERCP) imaging. In addition to a diagnosis tool, ERCP can also be a therapeuticmodality for placing stent to reduce symptoms of cholestasis. There were supporting laboratory findings suchas increased bilirubin level, alkaline phosphatase (ALP) and gamma glutamyltransferase (GGT) levels as wellas increased level of tumor markers such as carcinoembryonic antigen (CEA), carbohydrate antigen (CA) 19-9and cytological examination.Keywords: cholangiocarcinoma, jaundice, obstructive, ERCP ABSTRAKKolangiokarsinoma merupakan keganasan hati primer kedua yang paling umum, dimana insiden danmortalitasnya meningkat secara global. Usia rata-rata timbulnya gejala adalah 50 tahun. Pasien dengankolangiokarsinoma pada umumnya mengalami gejala ikterus obstruktif disertai dengan hasil laboratoriumdan pencitraan yang mendukung. Gambaran klinis yang predominan dari kolangiokarsinoma ekstrahepatik adalah obstruksi bilier yang menyebabkan ikterus, sedangkan kolangiokarsinoma intrahepatik menimbulkan gejala adanya massa intrahepatik yang menyebabkan nyeri kuadran kanan atas abdominal dan gejala terkaittumor lainnya yaitu kakeksia dan malaise. Diagnosis dan staging kolangiokarsinoma memerlukan pendekatanmultidisipliner antara lain laboratorium, radiologis, endoskopi dan analisis patologi.Pada kasus berikut ini seorang pasien didiagnosa kolangiokarsinoma yang ditegakkan berdasarkan pencitraanendoscopic retrograde cholangiopancreatography (ERCP). Selain untuk diagnosis, ERCP menjadi modalitasterapi dengan dilakukan pemasangan stent untuk mengurangi gejala kolestasis. Pemeriksaan laboratoriumyang mendukung antara lain peningkatan bilirubin, alkalin fosfat dan gamma glutamil transferase (GGT),peningkatan penanda tumor seperti carcinoembryonic antigen (CEA), carbohydrate antigen (CA) 19-9, dan pemeriksaan sitologi.Kata kunci: kolangiokarsinoma, ikterus, obstruktif, ERCP

Background: Successful cecal intubation is a primary quality indicator in colonoscopies and the mostimportant factor in detecting abnormal lesion in the colon. There are many factors that influence cecal intubationrate during colonoscopy procedure. The aim of this study is to evaluate the factors that influence cecal intubationrate in unsedated patients during colonoscopy. Method: A retrospective study of colonoscopy performed at Sardjito General Hospital, Jogjakarta, from January 2012 to August 2013. Age, sex, bowel preparation, indication for colonoscopy, colonoscopist, andreasons of incomplete colonoscopy from 564 colonoscopy reports were recorded and analysed. Results: Overall successful cecal intubation rate was 408 (72.34%). Causes of incomplete colonoscopywere patients discomfort or pain 41.66%, looping/redundant 28.85%, poor bowel preparation 18.59%, fixation/adhesion 6.41%, and bleeding risk 4.49%. Female was more unsuccessful in cecal intubation than male (31.50%vs. 24.05%; p = 0.048). The successful cecal intubation rates for gastroenterologists compared to gastroenterology(GI) fellows were 77.92% vs. 49.55%; p 0.001, and poor bowel preparation was more difficult to reach cecalthan good preparation (57.58% vs. 23.69%; p 0.001). Multivariate logistic regression analysis demonstratedthat female and poor bowel preparation were independently associated with lower cecal intubation rate, andgastroenterologists were independently associated less unsuccessful to reach cecal. Conclusion: The overall successful cecal intubation rate was still below the set standard. Several identifiedfactors that may predict lower of cecal intubation rate: the skill and experience of colonoscopists (GI fellows),poor bowel preparation and female.Keywords: cecal intubation rate, colonoscopy, unsedated colonoscopy

Background: Currently, the hospital-based studies on Helicobacter pylori (H. pylori) have demonstrated that the incidence of H. pylori infection tends to decline in Indonesia. On the other hand, no population-based study has ever been conducted. Therefore, our study was performed to evaluate the true incidence of H. pylori found among the population.Method: This study was a surveillance using cross-sectional design. The samples used in our study were randomly selected from 1,645 samples including those from five municapalities of Special Capital Region of Jakarta in 2006. Immunochromatographic test (ICT) was utilized to establish the diagnosis of H. pylori infection. The test has demonstrated high sensitivity and specificity for Indonesian populationResults: The seroprevalence of H. pylori infection among 310 patients was 52.3% (162 out of 310 patients) with mean age of 43.48 + 10.45 years. There was no difference regarding seroprevalence in both groups of 40 year and 40 years of age (52.3% and 52.2%). The highest prevalence of H. pylori infection was found in West Jakarta (66.1%); while the lowest prevalence was found in South Jakarta (41.0%). The incidence of H.pylori infection between those who were alcoholic was equal to those who were not alcoholic (46.2% vs. 52.5%).Similar result was also found between smokers and non-smokers (53.8% vs. 51.8%).Conclusion: In this study, we found that H. pylori seroprevalence remains high in the population. Various seroprevalence of H.pylori infection were found among five municipalities in Jakarta.Keywords: Helicobacter pylori, Jakarta, seroprevalence
