Background

Bruxism is a repetitive activity of the masticatory muscles that has been associated with orofacial disorders and psychosocial factors

Aim

The aim of this study was to investigate associations between possible awake bruxism (PAB) and family functioning, bullying, and dental caries in children 8‐10 years of age.

Design

A school‐based study was conducted with 739 pairs of parents/guardians and children. The parents/guardians answered the Family Adaptability and Cohesion Evaluation Scales for the establishment of family functioning. Information on bullying due to dental conditions was collected from the children. Dental caries in the children was evaluated using International Caries Detection and Assessment System criteria. A directed acyclic graph was used to define the theoretical model and select control factors. Descriptive analysis was performed, followed by multivariate logistic regression for complex samples.

Results

Considering the parental reports, fewer years of mother's schooling, a low family income, very flexible family adaptability, and cavitated dental caries were associated with PAB. The female sex, bullying, and orofacial dysfunction were associated with self‐reported PAB.

Conclusions

Therefore, the factors associated with PAB differ according to the reports of parents/guardians or self‐reports of children. Healthcare providers should consider both reports for a more effective intervention addressing PAB.
Enhanced Nrf2 up‐regulation by extracellular basic pH in a human skin equivalent system

Published: March 2021

Extracellular basic pH regulates cellular processes in wounds, and consequently influenced wound healing. Oxidative defence system modulation in the skin helps heal wounds, inhibits skin ageing and improves the skin condition. Moreover, the role of keratinocyte growth factor (KGF) and nuclear factor erythroid 2‐related factor 2 (Nrf2) in antioxidant systems has been reported in various skin models. However, the effects of extracellular basic pH on wound‐ or skin ageing‐related skin damage have not been examined. Thus, we investigated the antioxidant systems affected by extracellular basic pH in a 3D human skin equivalent system (3HSE). Extracellular basic pH decreased KGF expression and enhanced the oxidative defence system, and thus activated Nrf2 in the 3HSE. Additionally, extracellular basic pH and KGF treatment up‐regulated Nrf2 activation and its regulation of the oxidative defence system in the 3HSE. This indicates that Nrf2 up‐regulation is enhanced by reactive oxygen species production, rather than KGF, and by extracellular basic pH of the skin. The inhibition of skin damage through pH imbalance and KGF regulation suggests that the development of pH‐regulating or pH‐maintaining materials may provide effective therapeutic strategies for maintaining a healthy skin.

Published: March 2021

Background

Oral lichen planus (OLP) is a common chronic inflammatory condition with an undefined malignant transformation potential. There have been many attempts at providing a specific definition of OLP without conclusive outcomes. A new set of diagnostic criteria was proposed in 2016 by the American Academy of Oral and Maxillofacial Pathology (AAOMP) in an endeavour to resolve this issue, and this has not yet been evaluated. This study aimed to assess the utility of AAOMP proposed criteria for the diagnosis of OLP.

Methods

Five pathologists blindly assessed a cohort of 215 digital whole slide images (WSI) obtained from haematoxylin and eosin‐stained microscopic slides. Forty‐six WSI were included twice to assess the intra‐observer agreement. Included cases were diagnosed clinically as either OLP or oral lichenoid reaction. Each pathologist was asked to utilize the AAOMP histopathological criteria while assessing slides. The variations in diagnoses were assessed by unweighted kappa statistics.

Results

The level of intra‐observer agreement was very good (0.801 to 0.899). The level of inter‐observer agreement among the observers varied from good (0.658) to very good (0.842) when the responses were categorized as evident/compatible OLP versus no OLP and was good (0.62 to 0.725) when the responses were categorized as evident OLP, versus compatible OLP, versus no OLP. The clinico‐pathological correlation was 87.6%.

Conclusion

A reliable level of agreement can be achieved by pathologists for the diagnosis of OLP using the AAOMP criteria for differentiation between lichenoid and other conditions. There are still limitations in discriminating OLP from oral lichenoid lesions microscopically.

Published: March 2021

Background

Scaling and root planning (SRP) is the gold standard for non‐surgical periodontal treatment. Green tea as a supporting alternative in non‐surgical periodontal treatment has been suggested as a therapeutic option in the treatment of periodontitis.

Objective

To analyse the comparative effectiveness of green tea (Camellia sinensis) in its different forms and applications for the treatment of periodontitis.

Methods

We included randomized clinical trials evaluating green tea as an adjuvant therapeutic agent to scaling and root planning (SRP) in the treatment of periodontitis. For the meta‐analysis, we calculated standardized mean difference (SMD) and 95%CI comparing green tea and control (only SRP). We subgrouped by types of application forms of green tea. The certainty of the evidence was assessed through GRADE.

Results

Nine studies were included. The follow‐up time of treatments varied from 21 days to 6 months. The subgroup meta‐analysis showed that the green tea as sachet reduced probing bleeding (SMD = −0.71; 95%CI) and the gingival index (SMD = −0.78; 95%CI) compared to SRP with very low certainty of evidence. The sachet (SMD = −0.29; 95%CI) and dentifrice (SMD = −1.31; 95%CI) reduced plaque index with very low certainty compared to the control. All forms of application of green tea showed very low certainty of evidence (SMD = −0.27; 95% CI) in reducing the probing depth, as well as for the loss of clinical insertion (SMD = −0.42; 95% CI) with low certainty of evidence.

Conclusion

There was not a difference in the effectiveness of green tea isolated or in combination with SRP to reduce probing depth. Green tea adjunct to periodontal therapy showed very low certainty of effectiveness for the treatment of periodontal disease.
Telomere length is highly heritable and independent of growth rate manipulated by temperature in field crickets
Authors: Boonekamp Jelle , Rodríguez‐Muñoz Rolando , Hopwood Paul , Zuidersma Erica , Mulder Ellis , Wilson Alastair , Verhulst Simon , Tregenza Tom
Published: March 2021

Many organisms are capable of growing faster than they do. Restrained growth rate has functionally been explained by negative effects on lifespan of accelerated growth. However, the underlying mechanisms remain elusive. Telomere attrition has been proposed as a causal agent and has been mostly studied in endothermic vertebrates. We established that telomeres exist as chromosomal‐ends in a model insect, the field cricket Gryllus campestris, using terminal restriction fragment and Bal 31 methods. Telomeres comprised TTAGGn repeats of 38 kb on average, more than four times longer than the telomeres of human infants. Bal 31 assays confirmed that telomeric repeats were located at the chromosome‐ends. We tested whether rapid growth between day 1, day 65, day 85, and day 125 is achieved at the expense of telomere length by comparing nymphs reared at 23°C with their siblings reared at 28°C, which grew three times faster in the initial 65 days. Surprisingly, neither temperature treatment nor age affected average telomere length. Concomitantly, the broad sense heritability of telomere length was remarkably high at ~100%. Despite high heritability, the evolvability (a mean‐standardized measure of genetic variance) was low relative to that of body mass. We discuss our findings in the context of telomere evolution. Some important features of vertebrate telomere biology are evident in an insect species dating back to the Triassic. The apparent lack of an effect of growth rate on telomere length is puzzling, suggesting strong telomere length maintenance during the growth phase. Whether such maintenance of telomere length is adaptive remains elusive and requires further study investigating the links with fitness in the wild.

Authors: Murray Helen Burton , Pasricha Trisha S. , Jehangir Asad , Thomas Jennifer J. , Kuo Braden , Parkman Henry P.
Published: March 2021

Background

Rumination syndrome involves effortless, repeated regurgitation, and can overlap with other upper gastrointestinal disorders, including gastroparesis. To inform better diagnostic detection of rumination, we aimed to (1) identify frequency and characteristics of rumination in patients presenting for gastric symptom evaluation; and (2) assess demographic and clinical characteristics that could differentiate those with versus those without rumination.

Methods

Consecutively referred patients to two tertiary academic centers for gastric symptom specialty evaluation were included (N= 242). We obtained demographic information, gastric emptying scintigraphy, upper gastrointestinal symptoms using the Patient Assessment of Upper Gastrointestinal Symptoms (PAGI‐SYM), and Rome IV‐based rumination questionnaire.

Key Results

Thirty‐one of the 242 (12.8%) patients met criteria for rumination syndrome, of which 48% reported associated psychosocial impairment. Comparing those with rumination and those without, there were no differences in race, gender, frequency of diabetes, or frequency of gastroparesis. The median PAGI‐SYM score for rumination patients was higher than for those without (3.03 vs. 2.55; unadjustedp= 0.043, adjustedp= 0.30). This was largely driven by increased heartburn/regurgitation subscale scores (2.71 vs. 1.57, unadjustedp= 0.0067, adjustedp= 0.046), itself influenced by elevated daytime regurgitation/reflux (3.0 vs. 2.0; unadjustedp= 0.007, adjustedp= 0.048). There were no significant differences on the remaining PAGI‐SYM subscales.

Conclusions and Inferences

Rumination syndrome determined by Rome IV criteria was present in 12.8% of patients presenting for gastric symptom evaluation. Higher self‐report PAGI‐SYM heartburn/regurgitation subscale scores, particularly daytime regurgitation/reflux symptoms, were the only parameters that distinguished rumination. The PAGI‐SYM heartburn/regurgitation subscale could be used to screen for rumination, in addition to GERDAQ6.

Published: March 2021

Biotrophic pathogens are believed to strategically manipulate sugar transport in host cells to enhance their access to carbohydrates. However, mechanisms of sugar translocation from host cells to biotrophic fungi such as powdery mildew across the plant–haustorium interface remain poorly understood.

To investigate this question, systematic subcellular localisation analysis was performed for all the 14 members of the monosaccharide sugar transporter protein (STP) family in Arabidopsis thaliana. The best candidate AtSTP8 was further characterised for its transport properties in Saccharomyces cerevisiae and potential role in powdery mildew infection by gene ablation and overexpression in Arabidopsis.

Our results showed that AtSTP8 was mainly localised to the endoplasmic reticulum (ER) and appeared to be recruited to the host‐derived extrahaustorial membrane (EHM) induced by powdery mildew. Functional complementation assays in S. cerevisiae suggested that AtSTP8 can transport a broad spectrum of hexose substrates. Moreover, transgenic Arabidopsis plants overexpressing AtSTP8 showed increased hexose concentration in leaf tissues and enhanced susceptibility to powdery mildew.

Our data suggested that the ER‐localised sugar transporter AtSTP8 may be recruited to the EHM where it may be involved in sugar acquisition by haustoria of powdery mildew from host cells in Arabidopsis.

Authors: Toyohara Keiko , Kudo Yoshimichi , Nishimura Tomomi , Shoda Morio
Published: March 2021

A 36‐years‐old woman with a congenital corrected transposition of the great arteries, who underwent Senning and Rastelli operations, was admitted with a symptomatic supraventricular tachycardia. During an electrophysiological study, uncommon atrioventricular (AV) nodal reentrant tachycardia was induced. The coronary veins and coronary sinus did not connect to the systemic venous atrium. The His bundle electrogram (HBE) was recorded at the anterior septum of the mitral valve via the aorta. The target of ablation was the site of the earliest atrial activation during the tachycardia, 5 mm posterior to the AV node, and a successful cryoablation was performed using a transaortic approach. Both the antegrade and retrograde conduction of the slow AV nodal pathway was eliminated.

Published: March 2021

The knowledge of soil indicators during forest restoration is essential for understanding the recovery of ecosystem functions such as biomass production and water regulation. Despite this importance, in most restoration programs over the world, the soil remains under‐investigated. Here, we conducted a systematic literature review in order to determine: (1) the extent to which soil indicators are monitored during forest restoration in Colombia; (2) the type of soil indicators (e.g. physical, chemical, or biological) that are used for the monitoring; and (3) the regions where soil indicators are measured. We found 34 studies that report soil indicators. The most frequently studied restoration sites were 0–5 years old (36%). The majority (71%) of the studies only measured the soil characteristics at the topsoil. Soil sodium (Na) and phosphorus (P) concentrations were the most common chemical soil indicators reported by the studies. Soil biological indicators were the least frequently reported indicators. The studies rarely reported soil indicators that affect water movement directly. Of the retrieved studies, most included information about old‐growth forests (63%) or degraded sites (56%) for comparisons with forests undergoing restoration. Based on these results we provide recommendations for monitoring soil characteristics to assess the effectiveness of forest restoration projects in Colombia, and other tropical countries.
Family‐type public goods and intra‐household decision‐making by co‐resident South African couples
Authors: Guvuriro Sevias , Booysen Frederik
Published: March 2021

The current study examines sources of bargaining power that inform financial decision‐making processes within co‐resident couples and determines how bargaining power and decision‐making impact on family‐type public goods expenditure. The study uses South Africa's National Income Dynamics Study, which offers a direct measure of financial decision‐making responsibility. In terms of analysis, probit regression models are used to establish socioeconomic determinants of decision‐making for female partners in co‐resident couples, while ordinary least squares linear regression models are employed to determine the extent to which financial decision‐making responsibility and power influence expenditure on family‐type public goods by households. There is evidence of the relevance of economic factors in explaining financial decision‐making as postulated by the resource theory. Households with wives who gain a decision‐making role spend more on family‐type public goods. The findings suggest that policy has to focus on gender mainstreaming and empowerment, which would enhance the decision‐making role of women within co‐resident couples.
Artificial Intelligence, Forward‐Looking Governance and the Future of Security
Authors: Fischer Sophie‐Charlotte , Wenger Andreas
Published: March 2021

Over the last years, AI applications have come to play a role in many security‐related fields. In this paper, we show that scholars who want to study AI’s link to power and security should widen their perspective to include conceptual approaches from science and technology studies (STS). This way, scholars can pay attention to critical dynamics, processes, practices, and non‐traditional actors in AI politics and governance. We introduce two STS‐inspired concepts – the micro‐politics of design and development and co‐production – and show how the study of AI and security could benefit from them. In the final section, we turn to the study of AI in the context of Switzerland to underscore what aspects the two previously introduced concepts help to highlight that remain invisible for traditional approaches.

Discrepancies in the spatial extent of common GIS highway networks
Authors: Weber Joe
Published: March 2021

The Federal Highway Administration's Highway Performance Monitoring System (HPMS) and the U.S. Census Bureau's TIGER geospatial database are relied on by countless professionals, but the two databases differ by 6.9 million km (4.3 million miles), a discrepancy greater than the Federal Highway Administration's national total of 6.6 million km (4.1 million miles). While there are several methodological reasons why a GIS network will give different answers from the HPMS, these cannot explain a difference of this magnitude. The difference exists because TIGER was based on roads shown on USGS topographic maps, the majority of which are not considered public highways today. This overestimate of highway extent can affect a range of network operations in GIS. There is, however, reason to consider TIGER's overestimate an underestimate of the actual extent of roads in the country, as well as questioning which roads should be included in a study.

Published: March 2021

A novel three‐stage treatment process corresponding to three reactors (R1, R2 and R3) was developed for advanced defluoridation from industrial wastewater with fluoride concentration as high as 245 mg/L. In the first stage (R1), 90.6 ± 0.8% of fluoride was removed through CaF2 precipitation. Subsequently, the second stage (R2) was operated for advanced defluoridation through fluorapatite (FAP) precipitation. Importantly, the residual calcium in effluent of R1 participated in FAP precipitation in R2, reducing extra calcium dosage. In the third stage (R3), further defluoridation was observed in R3, and the final fluoride content in the effluent was as low as 0.15 mg/L in Phase 2. Advanced defluoridation from industrial wastewater with high‐concentration fluoride could be obtained through this process without coagulant addition to reduce sludge production and obtain relative pure chemical precipitates, and residual reagents could be utilized again in the next step during the process to decrease reagents dosage.

Authors: Le Hang Thu Thi , Likhitruangsilp Veerasak , Yabuki Nobuyoshi
Published: March 2021

This paper presents a building information modeling (BIM)-database-integrated system for estimating the construction costs of building projects. The proposed system consists of four main modules: (1) the relational database management module, (2) the visualized BIM-integrated module, (3) the cost estimation module, and (4) the BIM-integrated report module. The relational database management module is designed to store and update the necessary data, which are extracted from BIM models. The visualized BIM-integrated module assists users in visualizing the complex building elements while performing cost estimating. The cost estimation module computes construction cost components. It can also automatically adjust to the change of the building element parameters while estimating costs. This module can minimize human errors associated with manual data input and calculation. The BIM-integrated report module allows users to access and comprehend the results conveniently. As compared to traditional 2D CAD drawings, the proposed system offers a more efficient methodology for construction cost estimating through 3D models. It can also minimize time, costs, and errors in the cost estimating process for building procurement.

Published: March 2021

Wide range input voltage converters are merely required in photovoltaic and wind energy conversion systems which have dynamic output voltage due to irradiance and wind speed fluctuations. This paper presents a comprehensive analysis and design approach of grid connected buck-boost inverter for wide input voltage application. Sizing of a LC output filter component is emphasized in this paper. It is important to size the filter properly to obtain a trade-off between output current ripple and reactive power supplied into grid when inverter is in stand-by mode. A graphical method is employed to determine filter parameters. The presented method is found to be straight forward and easy from practical point of view.

Published: March 2021

We present the security weakness of encryption algorithm in the form of substitution-permutation network with multiple rounds of permutation and single round of diffusion proposed by W. Zhang et al. The types of chosen-plaintext and chosen-ciphertext attacks are successful against the cryptosystem, and the equivalent versions of keys for encryption and decryption are restored. The security analysis suggests that encryption using substitution-permutation network must be executed more than one encryption round to ensure the security. Our specific examples will demonstrate the cryptanalysis.
DYNAMIC FRICTION BEHAVIOR IN PRE-SLIDING REGIME OF PNEUMATIC ACTUATORS
Authors: Bo Tran Xuan , Long Do Viet , Yanada Hideki
Published: March 2021

This paper focuses on investigating friction behavior in pre-sliding regime and developing a new mathematical model of friction for fluid power actuators. Using pneumatic cylinders with different sizes, an experimental setup is built to measure friction force-displacement characteristics in presliding regime under various conditions of pressures in the cylinder chambers. A new mathematical model of friction for the pneumatic cylinders is proposed by incorporating a hysteresis function into the new modified LuGre model. The experimental results show that when the pressures are varied, friction of the pneumatic cylinders in pre-sliding regime is represented by behavior of a nonlinear spring. In addition, hysteresis behavior with nonlocal memory is obtained in the friction forcedisplacement characteristics and that the size of the hysteresis loop is increased with increasing pressures in the cylinder chambers. The simulation results show that the new friction model can accurately simulate the friction behavior of the pneumatic cylinders in pre-sliding regime as well as sliding regime.

MIMO channel sounding is essential for evaluating the MIMO transmission performance in real propagation environments. In this paper, we have developed a versatile channel sounder by using the GNU Radio and Universal Software Radio Peripheral (USRP) platform and the virtual antenna array method. The developed channel sounder is low cost and can be utilized flexibly for measurements in the UHF band. The performance of the developed channel sounder was validated through a T-junction cable connected test and an indoor channel measurement. The result showed that the performance quite agreed with the measurement of a VNA-based measurement system. The developed channel sounder is expected to be utilized for various kinds of propagation channel measurements.

Published: March 2021

In order to utilize the flow of a river to generate power, it is crucial to develop a system that is able to obtain and record the river’s characteristics in various aspects. A simple but effective method has to be created to allow researchers to collect and study the parameters of a river in order to predetermine the final build of the power generation model. A floating sensor that is able to collect and give a real-time data has been developed using readily available hardware as well as custom made parts. This paper describes a design methodology for river floating sensors and results from a case study performed in the actual controlled channel are presented to demonstrate the effectiveness of the design decisions.
A DATA RE-REPLICATION SCHEME AND ITS IMPROVEMENT TOWARD PROACTIVE APPROACH
Authors: Shwe Thanda , Aritsugi Masayoshi
Published: March 2021

With increasing demand for cloud computing technology, cloud infrastructures are utilized to their maximum limits. There is a high possibility that commodity servers that are used in Hadoop Distributed File System (HDFS) based cloud data center will fail often. However, the selection of source and destination data nodes for re-replication of data has so far not been adequately addressed. In order to balance the workload among nodes during re-replication phase and reduce impact on cluster normal jobs’ performance, we develop a re-replication scheme that takes into consideration of both performance and reliability perspectives. The appropriate nodes for re-replication are selected based on Analytic Hierarchy Process (AHP) with the consideration of the current utilization of resources by the cluster normal jobs. Toward effective data re-replication, we investigate the feasibility of using linear regression and local regression methods to predict resource utilization. Simulation results show that our proposed approach can reduce re-replication time, total job execution time and top-of-rack network traffic compared to baseline HDFS, consequently increases the reliability of the system and reduces performance impacts on users jobs. Regarding feasibility study of prediction methods, both regression methods are good enough to predict short time future resource utilization for re-replication.
ONSHORE-OFFSHORE FACIES CHANGE OF NGRAYONG SANDSTONE IN MADURA AREAINDONESIA
Authors: Surjono Sugeng Sapto , Gunawan Mustafid
Published: March 2021

Ngrayong sandstone composes a siliciclastic reservoir that produces oil for more than a century in North East Java Basin of Indonesia. Clean sand facies makes the best reservoir in western part of the basin, onshore East Java Island. Meanwhile, sand quality decreases eastward to Madura Island. In Madura, rock gradually changes to be more calcareous and shaly, due to the change of depositional environment. In offshore of Madura, the depositional environment is still questionable. This study is aimed to reveal differences between onshore and offshore facies of Ngrayong sandstone in Madura as their distribution is not well known and oil potential of Madura Strait is not well identified. Study methods consisted of geological field work, well correlation, and petrophysical analysis from several well data. The results show that Ngrayong sandstone was deposited during Middle Miocene, composed by interbedding of thickly bedded sandstone and alternating thinly bedded sandstoneshale. The succession is commonly intercalated by mudstone and thinly bedded limestone. At Madura Island, Ngrayong sandstone overlies the Early-Middle Miocene Tawun Formation, which both represent the Megasequence (MS) 3 interval. Due to regional subsidence and transgression during Late Miocene, Ngrayong sandstone and other equivalent rocks were overlain by monotonous mudstone and calcareous sandstone of Wonocolo Formation. The Ngrayong sandstone is evenly distributed in whole surface area of Madura Island and it spreads further 25-50 Km to the south and 100-125 Km to eastern part of offshore Madura Strait. Sandstone distribution is roughly depleted from the gross thickness hundreds of meters in northern part to only few centimeters in southeast part of study area. The facies changes to be more calcareous to the east, while the southward facies is shaly due to a deeper depositional environment. Despite of facies changing into shales or carbonate facies, Ngrayong sandstone potential in offshore Madura Strait needs to be considered as upside potential due to its distribution is wider than initial estimation, and its petrology and petrophysic data support it as a clastic reservoir.
WIND ENERGY DEVELOPMENT IN JAPAN AND VIETNAM
Authors: Tuan Phan Anh
Published: March 2021

This paper represents a research study on the wind power policies and the development of wind power projects in Japan and Vietnam, two countries in Asia with different social development history and economy. Japan has harnessed wind power as a source of green energy many years ago whereas the research on wind power in Vietnam has only been conducted in recent decades. After the earthquake-tsunami disaster in 2011, the Japanese government has prioritized the development of alternative sources of generating electricity including wind power to replace the dangerous nuclear power. This paper reviews and analyzes the development of wind power policies and projects both in Japan and Vietnam. The research results confirm that the Japanese government has the complete and clear policies on the development of wind power. This stability encourages national and foreign investment in the various development projects of the wind power plants. On the other hand, the laws and policies for wind development in Vietnam are not yet stable and many Decisions and Circulars have been promulgated over a decade by the Vietnamese government from 2007 to 2016 which result in the constraint of the development of wind power projects in Vietnam.

Authors: Budiwantoro Bagus , Djodikusumo Indra , Ramdan Ade
Published: March 2021

A decanter centrifuge machine has been developed and currently at a complete stage of a preliminary 3D design layout. The next phase is a production phase. In the production phase, an ideal component that is identical with the 3D model will never be realized. Every manufacturing process has unavoidable variations. If they are accumulated, they can be immense and may cause serious problems. The machine may fail. Thus, the analysis of geometry specification is necessary to be conducted. The main objective of this study is to design the geometry specification which includes their tolerance to assure that the machine will work and achieve its performance, considering variation in manufacturing process. The study consists of four stages, they are: (1) reviewing the 3D design layout, (2) identifying functional key characteristics, (3) analyzing each requirement to determine the geometric dimensioning and tolerancing schemes and (4) allocating tolerances. Every scheme was built through six steps, establish the performance requirements, draw a loop diagram, converting dimension to mean dimension, calculate mean value with stack tolerance, determine the method of tolerance analysis and calculate the variation of performance requirements. The tolerance analysis uses the worst case and statistical methods. They involve 45 fixed tolerances and 38 variable tolerances. The calculated variation data output of every requirement is elaborated to finalize tolerance value that will meet all requirements. Finally, the final tolerance values are allocated and set to component geometry. This analysis concludes that every final tolerance of variable tolerance values must be tighter for the worst case method, and only 42% for statistical method. Probability of machine will work and achieve its performance is 100% for the worst case method and 99.73% for the statistical method.
ENGINEERING GEOLOGY OF ALLUVIAL DEPOSITS IN YANGON AREA
Authors: Moe Khin Soe
Published: March 2021

Two-thirds of the Yangon area is covered by alluvial deposits, which are weak in their strength and highly permeable. As Yangon area has undergone very rapid development and expansion, its expansion of new satellite towns is mostly built on the alluvial deposit. Engineering geology study of alluvial deposits in Yangon area is therefore needed to ascertain the nature and properties of alluvial deposits at different locations and at various depths. The distribution of alluvial deposits in Yangon starts from Kyaukmyinthar area to the Letkikkone and along the flood plain of Yangon river and Hlaing river. The alluvial deposits are categorized into valley fill, marine, and flat plain types. The most common deposit types are CL, CH, SM, SC, ML according to the Unified Soil Classification. Standard Penetration Test (SPT) is performed for this research and samples collected from boreholes are tested in the laboratory. Based on the SPT value and the laboratory results, the bearing capacity calculations are made for the foundation condition. Groundwater level is noted on each bore holes for the hydrological characteristics. The ultimate bearing capacity of valley fill deposits are more than 200 kPa in Ahlon Township but the ultimate bearing capacity of most marine alluvium in Hlaingtharyar and N. Okkalarpa Townships are less than 100 kPa.
Microstructural Evolution During a Solid State Tube Pinch Weld of Type 304l Stainless Steel
Authors: Korinko Paul S.
Published: March 2021

Microstructure development is examined for a specialized spot weld that is used as a solid-state closure process for austenitic stainless steel tubing, referred to as pinch welding. In order to elucidate the microstructural evolution of the weld, a series of test welds were made at nominal conditions using tubing and production like components. These pinch welds normally terminate after twelve cycles of a 60 Hz AC weld process. In this study, production tubes were welded from one to twelve cycles and the microstructure and weld variables after each individual weld cycle number were characterized using radiography and optical metallography. Two electrochemical etchants were used to highlight different microstructural features. The study revealed that: (1) this type pinch weld is largely complete after about six cycles of 60 Hz AC current, half the weld time utilized; (2) the resistance, deformation, and closure length approach “steady-state” conditions after six cycles; and (3) both oxalic and nitric acid electrolytic etchants are useful for highlighting specific microstructural attributes of type 304 L stainless steel. Finally, two distinct microstructural regions can be identified for these welds: the edge of the weld, which is driven by concentrated deformation, recrystallization, and grain growth, and the center region, which is more typical of forge welding and micro-asperity breakdown followed by diffusion and grain-growth.

Analysis of Different Size Fractions Provides a More Complete Perspective of Viral Diversity in a Freshwater Embayment
Authors: Palermo Christine N. , Shea Dylan W. , Short Steven M.
Published: March 2021

Most studies of aquatic virus communities analyze DNA sequences derived from the smaller-size “free-virus” fraction. Our study demonstrates that analysis of virus communities using only the smaller-size fraction can lead to erroneously low diversity estimates for many of the larger viruses such as
Mimiviridae
,
Phycodnaviridae
,
Iridoviridae
, and
Poxviridae
, whereas analyzing only the larger->0.45-μm-size fraction can lead to underestimates of
Caudovirales
diversity and relative abundance.

Published: March 2021

The increasing frequency of macrolide resistance is an emerging issue in the treatment of
Mycoplasma genitalium
infection. Because evaluation of new commercial kits detecting
M. genitalium
and macrolide resistance is needed, we evaluated the performance and handling characteristics of the Allplex MG & AziR (Seegene), the Macrolide-R/MG ELITe MGB (ELITechGroup), and the ResistancePlus MG FleXible (SpeeDx-Cepheid) kits in comparison with those of an in-house real-time PCR and 23S rRNA gene sequencing used as the reference.

Disulfiram-induced epileptic seizures
Authors: Nogueira Violeta , Mendes Mafalda Azevedo , Pereira Inês , Teixeira Joana
Published: March 2021

Disulfiram has been widely used for over six decades in the treatment of alcohol dependence, as an aversive therapeutic agent. Despite having very few side effects when taken without concurrent alcohol consumption, some of these may underlie serious clinical complications. Epileptic seizure induction is a rare adverse effect of disulfiram and its aetiological mechanism is unknown. We present a hospitalised 47-year-old male patient with two episodes of generalised tonic-clonic seizures during treatment with disulfiram while abstinent from alcohol.

Objective

To compare the antimicrobial effect in vitro of a short-chain cyanoacrylate with a long-chain cyanoacrylate (Dermabond, Ethicon, Johnson and Johnson, USA) against bacterial strains.

Methods and analysis

The following bacterial strains were analysed:Staphylococcus aureus,Escherichia coli,Klebsiella pneumoniaandPseudomonas aeruginosa. For each microorganism, standardised sterile discs (6 mm) containing 10 µL of ethyl-cyanoacrylate and 2-octyl cyanoacrylate were applied to the plate. All plates received a blank filter-paper disc with no adhesive (control). All plates were incubated for 24 hours, after which the bacterial inhibitory halos, if present, were measured in millimetres in its greater length.

Results

Inhibitory halos were observed for both adhesives forS. aureus. Inhibition halos were observed only for ethyl-cyanoacrylate forK. pneumoniaeandE. coli. No inhibition halo was observed forP. aeruginosain any sample. The relationship between the total size of the inhibition halos and the diameter of the paper filter forS. aureuswas statistically significant compared with 2-octyl cyanoacrylate.

Conclusion

Data shown conclude that ethyl-cyanoacrylate showed in vitro bacteriostatic activity forS. aureus,E. coliandK. pneumoniae. 2-Octyl cyanoacrylate showed in vitro lower bacteriostatic activity only againstS. aureuswhen compared with ethyl-cyanoacrylate. No in vitro bactericidal activity of ethyl-cyanoacrylate or 2-octyl cyanoacrylate was observed.
