Authors: Memarian Shadman , Pawlowski Callie , Tumin Dmitry , Jose Folashade A. , Jamison Shaundreal D.
Published: August 2020

Objectives

Pediatric chronic abdominal pain (CAP) is typically managed in primary care settings, although specialty referrals may help patients access the full range of biopsychosocial treatment options. We investigated patterns of specialty referral (gastroenterology or mental health) among children with CAP seen in an academic pediatric primary care clinic.

Methods

We retrospectively identified patients age 4–17 years visiting our primary care clinic in 2016–2017 for abdominal pain, identified using International Classification of Diseases (ICD) codes. We excluded patients whose symptoms did not persist for 3 months or who were referred to a specialist before their symptoms had persisted for 3 months. Referral outcomes were assessed through December 2018.

Results

Of 320 patients with qualifying ICD codes, 253 were excluded because their symptoms did not persist for 3 months; 31 had already been referred to a specialist within 3 months of pain onset; and one chart could not be accessed. Of the remaining 34 patients (22/12 girls/boys, median age 10 years) 10 (29%) were referred to a gastroenterologist and none were referred to mental health specialists. No clinical or demographic factors reached statistically significant associations with gastroenterology referral, although pain duration was shorter among patients who were referred.

Conclusions

Children with CAP managed in our primary care clinic were seldom referred to specialists after their pain persisted over 3 months. Increasing focus on cognitive-behavioral therapies for chronic pain, and the low specialty referral rate, indicates that primary care practices should be prepared to offer these treatment modalities to children with CAP.
A new method of flow blockage collapsing in the horizontal pipe: the pipe-rotation mechanism
Authors: Feng Shaohua , Jia Wenguang , Yan Jinglu , Wang Chuanwei , Zhang Kerui
Published: August 2020

In dense pneumatic conveying, flow blockage is a severe problem in the horizontal pipe, so accelerating the collapse velocity of blockage can improve the efficiency of powder transportation. In this paper, we offered a new method of the pipe-rotation mechanism and focused on the effect of this method on blockage collapse from collapse velocity, mass flow rate, and the change of the particle region. The physical model developed is horizontal pipe-rotation geometry at a uniform rotational speed of 0, 150, 300, 450, and 600 rpm, respectively. Then we used a computational fluid dynamics and discrete element method (CFD-DEM) model to investigate a single slug of particles passing through these geometries. The results show that collapse velocity and the mass flow rate increase with increasing rotational speed, which proves that the pipe-rotation mechanism can accelerate the collapse of flow blockage evidently. Moreover, the pipe-rotation mechanism changes the particle region significantly, which is polarized in the lower half of the pipe. It is trusted that the findings reported in this paper well serve as a helping source for further studies toward dense pneumatic conveying.
Love, sadness and other mental states in the Middle Welsh Owain (and related texts)
Authors: Poppe Erich
Published: August 2020

This article explores the devices employed by the medieval Welsh narrator of Owain, or Chwedyl Iarlles y Ffynnawn (‘The Story of the Lady of the Well’), to convey emotions and the mental states of his characters to his audiences. Although he generally remains inaudible, he uses, at some crucial points, words and phrases denoting emotions in a narrow sense, such as love, sadness and shame, in order to direct and steer the audiences’ perception and their understanding of the narrative. A comparison with thematically related texts, Chrétien de Troyes’ Yvain, and its Old Norse, Old Swedish and Middle English translations, helps to assess the narrative role of literary emotions in the Welsh text.
‘He ne wiste nother of evyll ne gude’: A Prelapsarian Perceval
Authors: Hafner Susanne
Published: August 2020

Departing from the observation that the Middle English romance of Sir Perceval of Galles quotes from Genesis at two crucial moments, this study provides a coherent reading of the text, explaining some of its idiosyncrasies and triangulating it with the versions of Chrétien de Troyes and Wolfram von Eschenbach. What distinguishes the Middle English version from the continental texts are its purposeful absences, i. e. that which the author chooses to abbreviate or leave out altogether. The result is the story of a prelapsarian creature who stumbles through an Edenic landscape where time and mortality have been suspended and individual culpability does not exist. Sir Perceval’s non-existent biblical knowledge, blocked by his mother and ultimately brought to its end by a literal fall from his horse, leaves him invincible, ungendered and immortal. It also serves to explain his unapologetic violence as well as his complete lack of sexual desire. This bold experiment cannot last – Sir Perceval does eventually discover knighthood, masculinity and mortality. Unfortunately, these three are inseparably linked: being a knight, being a man and being dead are one and the same thing in Sir Perceval’s universe.
Hybrid Identity and the Morte Darthur’s Lady of the Lake
Authors: Myers Maggie Rebecca
Published: August 2020

This article examines Nynive, the second Lady of the Lake, in Malory’s Morte Darthur. It reads her in a hybrid context, arguing that her hybridity allows her to occupy a unique position within the Morte. This position goes beyond her roles in the Vulgate and situates her as a defender of Arthur’s court and a dispenser of justice within it. In turn, understanding Nynive’s hybridity allows us to understand how she finds and claims power in the Morte through assisting the court, upholding it from a positionality that is unique to her.
Integer factoring and compositeness witnesses
Authors: Pomykała Jacek , Radziejewski Maciej
Published: August 2020

We describe a reduction of the problem of factorization of integers n ≤ x in polynomial-time (log x)M+O(1) to computing Euler’s totient function, with exceptions of at most xO(1/M) composite integers that cannot be factored at all, and at most x exp $\begin{array}{}
\displaystyle
\left(-\frac{c_M(\log\log x)^3}{(\log\log\log x)^2}\right)
\end{array}$ integers that cannot be factored completely. The problem of factoring square-free integers n is similarly reduced to that of computing a multiple D of ϕ(n), where D ≪ exp((log x)O(1)), with the exception of at most xO(1/M) integers that cannot be factored at all, in particular O(x1/M) integers of the form n = pq that cannot be factored.
Analysis on dynamic feature of cross arm light weighting for photovoltaic panel cleaning device in power station based on power correlation
Authors: Hou Yuqing , Fu Yu , Chen Jiawei
Published: August 2020

The surface cleanliness of photovoltaic (PV) panel has an important impact on the efficiency of power generation. The excessive mass of cross arm has always affected the use of cleaning device. Based on the power correlation analysis, the dynamic characteristics of cross arm lightweight of PV panel cleaning device in the power station are proposed. Using the theory of information fusion to weigh it as a comprehensive influence factor, the power prediction value of the model output is transmitted to the cleaning device in real time: design the cleaning device of PV panel and optimize the topology of the mechanical cross arm. The experimental results show that the PV power is related to many meteorological factors, and the lightweight design of the cross arm is more conducive to the natural frequency and mode shape analysis of each mode of the cross arm structure.
Influence of unequal stator tooth width on the performance of outer-rotor permanent magnet machines
Authors: Wang Aimeng , Li Dashuang
Published: August 2020

Outer-rotor permanent magnet machines for low-speed and high-torque applications have been used due to their high moment of inertia and torque density. In this paper, the 12-slot/10-pole outer-rotor fractional-slot permanent magnet machine model is established by finite element analysis, the influence of unequal stator tooth width and tooth tip width is investigated for the PM machine, and five different schemes of stator tooth and tip width are designed and analyzed. Detailed comparisons of the performance characteristics of the machines are presented including important issues such as output torque, magnetic field distribution, and tooth flux density. It is shown that the torque density and cogging torque and efficiency can be effectively improved by choosing reasonable tooth and tip width, which lays a foundation for further optimum design and efficiency improvement of the machine.

Authors: Emanuelli L. , Molinari A. , Arrighetti G. , Garoli G.
Published: August 2020

The effect of binder content and WC grain size on the mechanical properties is widely investigated in literature. An increase in binder amount and WC grain size leads to a decrease in hardness and an increase in fracture toughness. Actually, these correlations are related to the influence of binder content and WC grain size through the contiguity and mean binder free path, which are the microstructural parameters that affect the mechanical properties. The aim of this study is to verify the dependence of the two microstructural parameters that govern the WCCo mechanical behaviour, namely the contiguity and mean binder free path, on the mechanical properties of an extended range of WC-Co samples, which differ in terms of Co content and tungsten carbide grain size.
O programa linguístico de Benveniste e a constituição da linguística textual proposta por Adam
Authors: Ciulla Alena
Published: August 2020

Diante das diversas perspectivas de estudos apresentadas sob a égide da linguística textual, faz-se necessário um posicionamento da parte de todo pesquisador que tenha o texto como objeto de análise. Neste artigo, investigamos os fundamentos da análise textual dos discursos, de Jean-Michel Adam. Retornando aos estudos que questionam os limites da ciência linguística, entre langue e a parole, que estão diretamente relacionados também à discussão do estatuto da frase, é em Benveniste que Adam encontra suporte para dar uma saída à questão. Situando o estudo do texto em uma linguística do discurso, Adam considera o texto como produto da enunciação e, portanto, na interdependência entre os domínios do semiótico e do semântico. Por fim, a partir da sugestão de um “novo aparelho de conceitos e definições”, Adam propõe categorias próprias para o texto, subdividindo o texto em segmentos, da proposição-enunciada à sequência, e explicitando tipos de ligação entre unidades textuais.
O signo linguístico entre Saussure e Benveniste: ainda de sua natureza “arbitrária” e “necessária” e sua relação com o sujeito falante/locutor
Authors: Teixeira da Silva Filho Jomson
Published: August 2020

A arbitrariedade do signo se configurou como um afastamento de Benveniste em relação a Saussure, ou uma ultrapassagem daquele em relação a este, ao propor a relação necessária entre os constituintes do signo linguístico. Neste artigo, questionamos essa ultrapassagem especialmente no que tange ao sujeito na teorização saussuriana como aquilo que o próprio Curso de Linguística Geral (1916) projetou para a ciência linguística futura e um princípio que foi aplicado por Benveniste em sua teorização sobre a linguagem. Argumentamos sobre a noção de sujeito em Saussure, e ainda, sobre a interpretação de Benveniste (1976[1939]) do signo através daquilo que foi possível ao autor ter acesso dos textos saussurianos, como destaca Normand (2009). Assim, não defendemos que Benveniste ultrapassa Saussure ao propor as duas dimensões da linguagem, semiótica e semântica, mas que Benveniste soube “ler” Saussure, tomando-o como “em primeiro lugar e sempre o homem dos fundamentos” (BENVENISTE, 1976, p.  35).
Benveniste e Agamben: o ético e o político na linguagem revelados pela blasfemia e pelo juramento
Authors: Marchioro Stumpf Elisa
Published: August 2020

O artigo analisa a contribuição do linguista Émile Benveniste e do filósofo Giorgio Agamben sobre os temas blasfemia e juramento, a fim de discutir suas implicações no tratamento do aspecto ético e político do exercício da fala. De Benveniste, estudam-se os textos “A blasfemia e a eufemia” e suas publicações sobre o juramento na Grécia e em Roma, que são cotejados com “O sacramento da linguagem: uma arqueologia do juramento”, de Agamben. Conclui-se que o juramento e a blasfemia são vestígios de uma experiência performativa da linguagem em que havia plena correspondência entre as palavras, as ações e o mundo e, como tais, são fenômenos privilegiados para revelar como o homem, ao enunciar para assumir-se enquanto sujeito, torna-se responsável por aquilo que fala.

The development of technology is increasingly rapid, teenagers are very active in using it from various sides of good and even technological workers. Part of the technology that is quite a lot of users is social media, a variety of the most widely used media such as YouTube, Instagram, Facebook, and chat applications. Plus the number of users of each social media is increasing every day. Like technology, language will also develop rapidly, language transformation will continue to move, but there are some things that need to be considered that language must also get guidance to stay good and not shift the originality of the language itself. The survey results of researchers, on some social media such as youtube and instagram, the average video maker on social media is people who follow western culture, city people, slang and even use contemporary alay language. Next too, most elementary school children use their gadgets to play games, youtube, and play Instagram. So it is deemed necessary to examine how the impact of the media on the acquisition of new language of elementary school children is studied in psycholinguistic studies.

Authors: Arifiyanto Fajar , Nuryatin Agus , Doyin Mukh
Published: August 2020

Utomo’s novels are very related to the theme of religion and culture. The language used tends to be simple but still interesting and beautiful so research on the form and function of language style is very interesting. The purpose of this study is to describe the form and function of language style in the three Utomo novels. Data collection is done by heuristic techniques or read by repeatedly. Data analysis method used is hermeneutics. Almost all types of figurative language styles are found, but for the sake of effective exposure, only three data would be presented as examples of the form of language style and the function of language style. The three most found figurative languages are metaphor, simile, hyperbole, personification, and sinekdoke. The function of language also varies, starting from clarifying the picture, increasing the impression, shortening the narrative, and describing the character's feelings. Fulfillment of these functions with simple but beautiful forms of language style makes Utomo's novels have high aesthetic value and are easily understood by readers.
Sternum Dehiscence: A Preventable Complication of Median Sternotomy
Authors: Ata Emin Can , Beyaz Metin Onur
Published: August 2020

Background: The incidence of sternal dehiscence following cardiothoracic surgery via sternotomy is rare. It causes serious patient dissatisfaction and leads to higher hospital costs. For years, each clinic has made efforts to reduce this complication. Here, we aimed to summarize our techniques to prevent dehiscence.
Material: This retrospective study included two groups operated via median sternotomy from March 2009 to May 2019. The first group included 1,105 consecutive patients who only received sternum wire for sternum closure from March 2009 to October 2013. The second group included 1,559 consecutive patients operated from January 2014 to May 2019; preventive closure techniques were performed for predefined high-risk patients in this group. These closure techniques included polyglyconate (Maxon) or simple longitudinal reinforced sutures, sternal cable or sternoband, sternal plate, and Robiscek technique.
Results: All patients in Group 1, and 63.8% (995/1559) patients in Group 2 received sternal wire only (P < .001). In Group 2, we applied preventive closure techniques to 564 (36.2%) patients. There was no sternal dehiscence in Group 2, whereas 29 (2.6%) patients postoperatively suffered sternal dehiscence in Group 1; this was statistically significant (P = .001, OR:85.5, 95%CI:5.22-1400.4). The overall incidence of mediastinitis was 0.94%. The incidence significantly was lower in Group 2 (P = .004, OR:3.6, 95%CI:1.52-8.82). Sternum-related mortality in Group 2 also was lower (0.54% versus 0.06%, P = .048, OR:8.5, 95% CI: 1.02-70.75).
Conclusion: Sternal dehiscence can be avoided by careful perioperative risk assessment and enhanced closure techniques. The same special consideration may significantly reduce mediastinitis and sternal-related mortality.

Aim. To assess the adherence to physician recommendations and to study its relation to the post stroke anxiety and depression after stroke. Material and methods. The study was done on the basis of patients hospitalized with the diagnosis of stroke/transient ischemic attack to Lubertsy district hospital №2 during 2009-2011. In 2,8 (2,1; 3,5) years after discharge we requested patients’ life status. The examination was performed, questionnaire of adherence developed in SSRCPM, that include Moricky-Greene test (MGT), short in-hospital anxiety scale HADS. Results. Totally 960 patients included, of those 370 replied to adherence questions, 360 (37,5%) men and 600 (62,5%) women, mean age 71,1±9,8 years (25-99 y.). In hospital 207 (21,6%) died, 753 (78,4%) were discharged for outpatient care. We successed to know the life status of 688 (91,4%) patients, and failed with 65 (8,6%). After discharge from the hospital 237 (31,5%) persons died, refused to be examined 77 (10,2%), 374 (49,7%) were examined, of those 370 agreed to fill in questionnaire. By the HADS score depression was found in 256 (69%), anxiety in 171 (46,2%). By the MGT adherent were only 49 (13,2%), not enough adherent 61 (16,5%), non-adherent 229 (61,9%). We found statistic relation of adhrence parameter existence and value (χ2 =8,93; р=0,003), the same relation was found for the anxiety and adherence (χ2 =6,29; р=0,01). Depression is highly probable (about 2 times) increased the chance to have low adherence parameters (OR=2,035; 95% CI 1,272- 3,254). Anxiety spectrum disorders increased the chance to be nonadherent in about 2 times too (OR=1,775; 95% CI 1,131-2,784). Conclusion. We revealed a high prevalence of depression and anxiety in patients after MI that can negatively affect adherence to physician recommendations.

Aim. To study the age-related changes in structure of myocardium of the left ventricle and their relation with telomere length. With the age even in absence of cardiovascular diseases (CVD) and risk factors (CRF) there is a changing of the left ventricle (LV) myocardium structure. Probable mechanism of the age-related changes is cell ageing. One of the markers of cell ageing is telomere length (TL) that is also a marker of biological age. Material and methods. After screening we included 303 persons at the age 23-91 y.o. without clinical signs of CVD. All participants underwent transthoracal echocardiography by the standard method. Telomere length was measured in leucocytes on the genomic desoxyribonucleic acid (DNA) by real-time polymerase chain reaction method (PCR). We measured the relative length of telomeres. For the assessment of parameters relations we used correlational logistic regression analysis and build-up of multidimensional regression models. Results. Older age group (women >55 years and men >45 years) of those without significant signs of CVD and CRF comparing to the group of younger persons we found thicker LV myocardium and its concentric remodeling. TL was significantly linked with the age (β=-0,012, p=0,0001). Also we found the relation of TL with LV structure parameters: interventricular septum thickness (IVST) (β=-0,028, p=0,01), relative wall thickness (RVT) (β=-0,012, p=0,02) using the age and CRF. However shorter telomeres (<9,75 units) were not related to the increase of IVST (OR=1,44; 95% CI 0,84-2,47; p=0,18), posterior wall thickness (PWT) (OR=1,56; 95% CI 0,37-6,59; p=0,55) and RVT (HR=1,40; 95% CI 0,74-2,65; p=0,31). Conclusion. Left ventricle hypertrophy and its concentric remodeling in older age group without CVD and CRF shall be regarded as age-related. LT, cell ageing marker, is not related to the age-specific changes of LV structure.

Aim. To study the prevalence of risk factors (RF) of cardiovascular diseases (CVD) in the teaching staff of primary schools in Tomsk city. Material and methods. Totally 154 teachers studied (staff of 2 general education schools of Tomsk) at the age of 21-71 y. Mean age 46,6±10,9. Response — 84%. Results. Prevalence of arterial hypertension (AH) among the staff was 51,9%, and primary onset of AH — in 3,2%. Less than a half of teachers with AH took antihypertension therapy (42,8%) and just in 15% of those we found target levels of blood pressure during business day. Prevalence of smoking was 7,0%. We found a high prevalence of alimentary CVD risk factors. Two thirds of the staff were overweight (68,8%). Prevalence of excessive bodyweight was 33,1% and of obesity — 35,7%, of abdominal obesity — 40,2%. In teaching staff there was high level of hyperglycemia (12,1%), hypercholesterolemia (78,0%) and hypertriglyceridemia (32,0%). Insufficient physical activity was noted in 30% of teachers. Conclusion. The main points are found for the development and implementation of preventive strategies in the group — effective control over AH and correction of alimentary-dependent RF of CVD.
Optimal Taxation with Endogenous Default under Incomplete Markets
Authors: Pouzo Demian , Presno Ignacio
Published: August 2020

How are the optimal tax and debt policies affected if the government has the option to default on its debt? We address this question from a normative perspective in an economy with noncontingent government debt, domestic default and labor taxes. On one hand, default prevents the government from incurring future tax distortions that would come along with the service of the debt. On the other hand, default risk gives rise to endogenous credit limits that hinder the government's ability to smooth taxes. We characterize the fiscal policy and show how the option to default alters the near-unit root component of taxes in the economy with risk-free borrowing. When we allow the government to default and calibrate the model to Spain, fiscal policies are more volatile, borrowing costs are higher, indebtness and welfare are both lower than in two alternatives economies, one with only risk-free debt available and the other with government's commitment to the default strategy.

Authors: Ustinova T.V.
Published: August 2020

This study aims to clarify the methodological status of metaliteracy and define the role of communicative competence in the structure of metaliteracy. It is stated that metaliteracy is to be regarded as the complex cognitive-communicative information competence. Metacompetence is defined as the person’s ability and readiness for judgment, reasoning, meaning construction and decision-making in learning and communication on the basis of critical selection, processing and evaluation of information. Contribution of linguistic, sociolinguistic and pragmatic competences to information processing ability is analyzed. It is concluded that information processing is communicatively mediated. The didactic value of metacognitive awareness in information processing is highlighted.
Phraseologisms in the Works of the Avar Writer Musa Magomedov with the Kver "Hand" Component
Authors: Sirazhudinov R.M.
Published: August 2020

The question of the structural types of phraseological units was considered as on the material of the Caucasian languages. As for the Dagestan languages, there are works that raise questions of structural and grammatical analysis and the structural model of phraseological units. Phraseological units of the Avar (Magomedkhanov M.M., Khangereev M.-B.D.-G. and others, information about which will follow below), Lezghian (Gyulmagomedov A.G.; Ramaldanov A.R.), Rutul (Makhmudova S.M.)

Published: August 2020

Background: The work ability index (WAI) is a very important factor in planning a job and selecting suitable people for different occupations, and it can be affected by different factors. The aim of this study was to investigate the effect of insomnia severity on the employees’ work ability in a construction project.
Methods: This descriptive-analytical research has studied 213 employees of construction projects. Morin insomnia severity index (ISI) was used to evaluate the insomnia severity. Moreover, work ability was assessed using a questionnaire designed by the Finnish Institute of Occupational Health. Statistical data analysis was performed by SPSS19.
Results: The mean age and working experience of the individuals were respectively 36.2 and 11.27 years. The mean and standard deviation of the insomnia severity index was 6.76(2.5). Multiple linear regression analysis showed that insomnia severity, marital status, type of employment, and smoking had a significant effect on work ability index (WAI); so that the mentioned variables explained about 24% of the WAI variance.
Conclusion: Since sleep disorders and poor sleep quality can significantly decrease the work ability of employees, it is important to pay attention to sleep-rest programs to maintain and increase work ability and productivity.

Published: August 2020

Background: The occurrence of fire and explosion accidents in the process industries is accompanied by the gradual release of large amounts of energy. The DOW Index is one of the methods of evaluating fire and explosion in the process industries. The present study used the fuzzy logic method to improve the results of the fire and explosion risk analysis method and reduce their uncertainty (error in achieving the correct result).
Methods: In the present cross-sectional study, having analyzed the gas separation process, the DOW index was applied to study high-risk equipment. Then, to optimize the behavior of the parameters affecting the DOW index, each weight parameter was assigned to between 0 and 1, and the membership functions of each degree of risk were determined based on the fuzzy rules classification system. The five selected linguistic variables based on membership functions were used to assess the risk level.
Results: Considering butane, the level of fire and explosion risk was 231.3, which was less risky than the fuzzy logic result of 248.6. Methane risk was calculated according to the fire and explosion index of 262.1 while using fuzzy logic that was 265.6. The lowest risk difference was observed between the two methods for ethane (258.9 conventional method and 259.1 fuzzy method results). The risk level calculated by DOW for propane was 243.6, and the risk level was 255.1 while using fuzzy logic.
Conclusion: Although both methods yielded a high degree of risk, fuzzy logic results indicated higher numerical values comparing to the conventional DOW method. Compared to the conventional DOW method, fuzzy logic results are closer to reality with higher confidence levels.

Background: Risk perception and employees' attitudes towards safety is one of the requirements for establishing safety culture and having a safer working environment. If the attitude of employees to safety can be improved and accomplished, their safety performance will also be improved. So, to achieve an appropriate working environment, it is necessary to measure a person's perception of safety. The current study aims to explore the relationship between attitudes and safety performance among employees of the cement factory in Fars Province in Iran.
Methods: The present study is sectional analytical research, which was conducted among employees of the cement factory in the south of Iran in 2018. The required information was collected through the attitude questionnaire and safety performance. Finally, 130 questionnaires were completed. The data analysis was carried out through the SPSS software version 24 by using Kruskal–Wallis tests and man Whitney tests.
Results: The mean safety attitude was determined by 3.85(0.28). According to the results, there is no significant relationship between the level of safety attitude with age (P=0.32), the degree of education (P=0.36), work experience (P=0.52), accident numbers (P=0.47) and also the education (P=0.320). On the other hand, the safety attitude showed a significant relationship with safety performance (P=0.001).
 Conclusion: According to the results of the study and the significant relation between the safety attitude and performance, functional improvements in employee's safety attitudes could be achieved by planning and taking occupational health preventive measures.

COUNTER-RADICALIZATION IN EARLY CHILDHOOD THROUGH EFFECTIVE COMMUNICATION BETWEEN EDUCATION STAKEHOLDERS IN BIMA
Authors: Asyari Akhmad , Kadri Kadri
Published: August 2020

This research reveals the reality of early childhood education in Bima, West Nusa Tenggara as an area prone to radicalism, especially to see the policies and implementation of the counter-radicalization agenda in early childhood, including portraits of communication between stakeholders in tackling the spread of radicalism in Bima. This qualitative research took place from August 2018 to July 2019. The results showed that early childhood education institutions in Bima had not maximally used counter-radicalization content as teaching material even though they lived in the areas prone to radicalism. Communication between education stakeholders such as parents, educators, and the government has also not been effective. This is reflected in the lack of collective counter-radicalization action, so that preventive steps to counter radicalism seem minimal. The lack of coordination and communication for education against radicalization counter-narratives at the early childhood level has made hopes for an inclusive generation in Bima to be born.
Evaluating the Potential of Applying Machine Learning Tools to Metabolic Pathway Optimization
Authors: Ng Wenfa
Published: August 2020

Successful engineering of a microbial host for efficient production of a target product from a given substrate can be viewed as an extensive optimization task. Such a task involves the selection of high activity enzymes as well as their gene expression regulatory control elements (i.e., promoters and ribosome binding sites). Finally, there is also the need to tune expression of multiple genes along a heterologous pathway to relieve constraints from rate-limiting step and help reduce metabolic burden on cells from unnecessary over-expression of high activity enzymes. While the aforementioned tasks could be performed through combinatorial experiments, such an approach incurs significant cost, time and effort, which is a handicap that can be relieved by application of modern machine learning tools. Such tools could attempt to predict high activity enzymes from sequence, but they are currently most usefully applied in classifying strong promoters from weaker ones as well as combinatorial tuning of expression of multiple genes. This perspective reviews the application of machine learning tools to aid metabolic pathway optimization through identifying challenges in metabolic engineering that could be overcome with the help of machine learning tools.

Published: August 2020

The deep Cretaceous tight sandstone in Kuqa Depression of Tarim foreland basin is an ultra-low porosity and ultra-deep gas-bearing reservoir, which is characterized by small pores, fine throats, and poor connectivity. The wireline logging responses are so complex, and especially, it is difficult to identify fluid types from resistivity logs. Based on acoustic, density, and neutron logs response differences in gas and water layers, effective fluid sensitivity factors are constructed for gas layer identification. From conventional logs, acoustic-neutron porosity difference, density-neutron porosity difference, and triple-porosity ratio are all sensitive parameters to the gas layer. From the NMR logging response mechanism, the density and NMR porosity difference, and T2 geometric mean of the movable fluid are also two sensitive parameters to the gas layer. Based on these parameters, a series of fluid typing charts are constructed and their adaptabilities are analyzed and compared. By contrast, NMR log interpretation is better, and triple-porosity comprehensive method from conventional logs is also effective when NMR logging is not available. Finally, the comprehensive fluid typing strategy by combining some methods for ultra-low porosity tight sandstone is summarized and optimized. This study is another alternative for fluid identification using non-electrical logs.

Authors: Fang Qiang , Maldague Xavier
Published: August 2020

Infrared thermography has already been proved to be a significant method in non-destructive evaluation since it gives information with immediacy, rapidity and low cost. However, the thorniest issue for wider application of IRT is the quantification. In this work, we proposed a specific depth quantifying technique by employing the Gated Recurrent Unites (GRU) in composite material samples via pulsed thermography (PT). Carbon Fiber Reinforced Polymer (CFRP) embedded with flat bottom holes were designed via Finite Element Method (FEM) modeling in order to precisely control the depth and geometrics of the defects. The GRU model automatically quantify the depth of defects presented in the Plexiglasses materials. The proposed evaluated the accuracy and performance of synthetic plexiglasses data from FEM for defect depth predictions.
An Engineering Theory of Evolution
Authors: Castle Simeon , Grierson Claire , Gorochowski Thomas
Published: August 2020

Biological technologies are fundamentally unlike any other because biology evolves. Bioengineering therefore requires novel design methodologies with evolution at their core. Knowledge about evolution is currently applied to the design of biosystems ad hoc. Unless we have a unified engineering theory of evolution, we will neither be able to meet evolution’s potential as a design tool, nor understand or limit its unintended consequences on our designs. Our concept of the evotype offers a conceptual framework for engineering the evolutionary potential of biosystems. We show how a biosystem’s evolutionary properties might be rationally designed by engineering aspects of genetic variation, designed function, and natural selection. This idea could apply to all biosystems – from individual proteins to communities of whole-cells or even entire ecosystems – whether the goal is to direct evolution in the design process, or to limit its impacts during application. These principles could even be used beyond the realm of bioengineering to design entirely synthetic evolving auto-adaptive technologies.
