Abstract
This research aims to delve into the understanding of acid-base concepts among students at SMA Negeri 1 Muara Batang Gadis from a macro to micro perspective. The research method used is qualitative study with a descriptive approach. Data were collected through observation, interviews, and analysis of documents related to the curriculum and chemistry learning materials. The results show that students' understanding of acid-base concepts is still limited at the macro level, with minimal understanding at the micro level. This indicates the need for a more holistic and integrated approach to learning, incorporating macro, micro, and symbolic theory in the teaching of acid-base concepts. Recommendations for further development include the use of integrated learning approaches that incorporate various methods, including laboratory experiments, simulations, and technology-based learning, to enhance students' understanding of concepts from a macro to micro perspective.
THERMOWELL FATIGUE LIFE PREDICTION USING FINITE ELEMENT ANALYSIS
Authors: Norazmi Danish Luqman , Lemma Tamiru Alemu 
Published: February 2024

The objectives of the research involve developing the procedure for fatigue life prediction using the S-N curve for the thermowell material and investigating the effects of fluid velocity, fluid density and cyclic loading on the thermowell structure using the engineering drawing tool, AutoCAD 2022, and simulation software, ANSYS Workbench 21.1. By comparing the results for the proposed fatigue life estimation to Diwakar’s study on fatigue life estimation of thermowells in supercritical operation, the percent error obtained was 0.11%, which indicates that the proposed method is an accurate and reliable tool to perform fatigue analysis. Afterward, the parametric study of the thermowell model was conducted to investigate the effects of fluid velocity, fluid density and geometric dimensions on the fatigue life of a thermowell. There were six load cases investigated for two thermowells, which were designed based on the minimum and maximum dimensional limit of the thermowell performance test code PTC 10.3 TW-2016. The parametric study results showed that the minimum thermowell performed better for all the load cases, which obtained a maximum number of cycles to failure of 8898 cycles for a maximum stress value of 869 MPa. Furthermore, the higher the fluid velocity and density, the higher the likelihood and occurrences of resonance, the lower the number of cycles to failure. Similarly, the higher the natural frequency of the thermowell, the lower the likelihood and occurrences of resonance; hence, the higher the number of cycles to failure. It was observed that the point where the stress value is highest, or the stress concentration zone, is the area between the flange and thermowell neck, which was consistent with the thermowell performance standard codes of practice, PTC 19.3 TW-2016.
Keywords: Fatigue analysis, parametric study, resonance, stress concentration zone, supercritical, vortex shedding frequency
COMPUTED-ASSISTED DIAGNOSIS IN DIAGNOSTIC CERVICAL CANCER IMAGING : A TEN YEARS SYSTEMATIC REVIEW
Authors: Kusuma Dewi Rahmita , Kurnia Dewi Asri , Meitadani Nandya 
Published: February 2024

Background: Cervical cancer is one of the most common malignant tumors in the world, and it is the fourth leading cause of cancer in women. The morbidity and mortality of cervical cancer in the developing countries are distinctly higher than those in the developed countries. Computer-assisted diagnosis is key for scaling up cervical cancer screening, but current algorithms perform poorly on whole slide image analysis and generalization.
The aim: This study aims to show about computed-assisted diagnosis in diagnostic cervical cancer imaging.
Methods: By comparing itself to the standards set by the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) 2020, this study was able to show that it met all of the requirements. So, the experts were able to make sure that the study was as up-to-date as it was possible to be. For this search approach, publications that came out between 2014 and 2024 were taken into account. Several different online reference sources, like Pubmed and SagePub, were used to do this. It was decided not to take into account review pieces, works that had already been published, or works that were only half done.
Result: In the PubMed database, the results of our search brought up 153 articles, whereas the results of our search on SagePub brought up 180 articles. The results of the search conducted for the last year of 2014 yielded a total 53 articles for PubMed and 72 articles for SagePub. The result from title screening, a total 18 articles for PubMed and 27 articles for SagePub. In the end, we compiled a total of 10 papers. We included five research that met the criteria.
Conclusion: Computed-assisted medical diagnosis can successfully complete a variety of medical tasks by efficiently exploring the essence of a large amount of clinical data. The colposcopy-guided cervical biopsy is essential for detecting CIN in cervical cancer screening, but there are difficulties with increasing sensitivity globally.

Authors: Maharani Shabrina , Ramadani Latifah 
Published: February 2024

Background: The complex disease progression and treatment challenges affect the overall prognosis in myasthenia gravis (MG) patients. Recent advancements in managing MG have brought about significant progress in attaining complete stable remission as the treatment objective. This study aims to systematically review the prognosis of MG in literatures of the last 10 years.
Methods: This systematic review complied with the PRISMA 2020 standards and focused on full-text English literature published between 2014 and 2024. Articles such as editorials and review papers from the same journal, as well as submissions lacking a DOI, were excluded from consideration. Literature was sourced from online platforms like PubMed and SagePub.
Result: We found 627 articles on PubMed and 810 articles on SagePub. Restricting our search to the past decade (2014-2024), PubMed presented 425 articles, whereas SagePub presented 309 articles. From these, we selected 5 papers meeting our criteria, with 2 from PubMed and 3 from SagePub.
Conclusion: Significant progress has been achieved in treating MG over the past decade. While some patients experience spontaneous remission, the majority require treatment with steroids or similar drugs. Other treatment modalities such as monoclonal antibody treatment, pulmonary function testing, and thymectomy can be employed to improve the prognosis of MG.

Published: February 2024

Este trabalho tem por objetivo discutir a evasão no ensino superior sob a percepção das predisposições, causas e consequências. Assim alinha-se a uma revisão bibliográfica de natureza exploratória. Observa-se que a evasão no ensino superior ainda padece de maior precisão no seu cálculo e conceito. São multivariáveis as causas da evasão, destaque prevalecido para os fatores financeiros, acadêmicos e aspectos psicológicos e individuais. Neste contexto a mitigação dos índices de evasão estudantil é fator incansável das agendas institucionais e governamentais e produz políticas públicas com resultados ainda aquém dos perspectivados. Diante disto observa-se na construção do estudo que a diminuição efetiva dos índices de evasão acontecerá apenas com a melhora nas condições de permanência dos estudantes através de políticas que alinhem fatores construtivos nesta permanência no universo do ensino superior.

Published: February 2024

Gasification of biomass can be done with pure oxygen or with ambient air. We have chosen gasification with ambient air in our project for costs considerations. Relative humidity (RH) of the air we used with a downdraft co-current gasifier is monitored in this paper. RH sensor used in this paper presents a capacitor which depends on the amount of water contained in the gaseous mixture. That RH, behaving as a variable capacitor is inserted in serial with the RC circuit of an astable multivibrator. Frequency of the oscillator is dependent of the resistance and the capacity which depends on the RH. We have inserted the RH sensor as a variable capacitor in the RC circuit of a NE555 oscillator. From the RH sensor datasheet, a mathematical model has been developed and the equation giving RH found to be $$Rh=496,23 * ( {1.44*T \over (R_4+2R_2 )* C_55}) -443,26.$$ The frequency of the oscillator is calculated with Arduino and the RH is deduced. Temperature can be measured with a K type thermocouple from 25 to 1024C with accuracy of +/-1.5C.The effect of temperature on the RH is also taken into account. Using Arduino Uno3 as a computer, we have calculated corrected RH respective to temperature and displayed both ambient and real RH on 20 columns with 4 lines LCD display. Arduino has also enabled us to save measured data in an Excel sheet, allowing us to analyses measured temperature and RH and plot different curves from it. The same circuit is also used to monitor RH of produced synthesis gas. Results of the Arduino temperature and monitoring system shows that visual observation of air and human feeling can be very misleading in respect to the air RH.

Published: February 2024

Introduction: The liver is one of the principal organs of our body involved in over 500 physiological functions related to metabolism, digestion, immunity, and storage of nutrients, which makes it an essential organ to preserve life. The aim of my study is to measure the different size of the liver sonographically in a randomly selected patients sample and identify factors that affect liver size.
Methods: In this cross sectional study100 subjects were evaluated for liver length in a private care setting during a one-year study period from 01.01.2021 to 31.12.2021 after informed written consent. Diagnosis of liver diseases, gender differences, liver and non -liver involvements and risk factors were obtained from the subjects. Sonographic measurements of the liver in centimeters were taken from the participants.
Results: The average liver size in the midclavicular line was 15.0 ± 1.5 cm; the average for females was 14.9 ± 1.6 cm and 15.1 ± 1.5 cm for males. 29% of all patients were male with various liver pathologies while 47% of patients were both male and female but shared the same liver pathology, the remaining 24% of patients were female with different pathologies of the liver. Minimum age of the study population was 6 years and the maximum age were 82 years. Regarding occupations of study population, 16% were doing service,29% were housewives,18% were students. Most of the study subjects were from Chattogram (98%) and 32% of the patients had a history of smoking. Liver size exceeded 16 cm in 53% of patients had liver or non-liver involvement and 47% are liver involvement. The fatty changes in the liver Grade I were the most common finding (36%).
Conclusions: Sonographic measurement of liver length can lead to early diagnosis of various liver diseases.
The City as Dining Room, Market and Farm
Authors: Franck Karen A 
Published: September 2005

AbstractFood has been sold on the street ever since people have lived in town settlements. Encouraging social exchange and interaction, the public consumption of food brings vitality and conviviality to urban life. In recent years, the sale of food in upmarket cafés and speciality shops has intensified, becoming a tool of urban regeneration. Here, Karen A. Franck, the guest‐editor of this issue, introduces the themes behind ‘Food + the City’ and suggests why architects and planning professionals should pay attention to ‘the city's multiple functions as dining room, market and farm’.
Raw, Medium, Well Done: A Typological Reading of Australian Eating Places
Authors: Hurst Rachel , Lawrence Jane 
Published: September 2005

AbstractTaking their cue from the culinary criteria most often applied to the cooking of a beefsteak, Rachel Hurst and Jane Lawrence develop a taxonomy of design for eating establishments in Australia. They find examples of the ‘raw’ in Melbourne's buzzing Centre Place, the ‘medium’ in a chain of Italian restaurants in Adelaide, and the ‘well done’ at The Restaurant at the Art Gallery of New South Wales in Sydney.
Blurring Boundaries, Defining Places: The New Hybrid Spaces of Eating
Authors: Satler Gail 
Published: September 2005

AbstractRestaurants and food franchises have become ubiquitous in public spaces around the world, whether one is visiting a museum or concert hall in Europe, Asia or North America, or places of interchange, such as railway stations and airports. Gail Satler discusses the spatial and social transformation that the placement and design of these dining spaces and food stalls have effected, as they invite and guide movement not only within their immediate environment, but also across the greater cityscape.
Out of the Kitchen and onto the Footpath
Authors: Carter Louisa 
Published: September 2005

AbstractIn Brisbane, southeast Queensland, the number of people eating out in restaurants has increased almost fourfold in just over a decade. The emergence of public dining places on the footpaths has reinvented the city. Louisa Carter looks beyond the attractive veneer of well‐clipped vegetation and heritage street furniture to the socioeconomic and political forces behind the development, and asks whether as a trend it is effectively cocooning urban residents ‘in comfort and convenience’ and is in danger of creating an artificial urban panacea.
Creep mechanism of porous MCFC Ni anodes strengthened by Ni3Al
Authors: Kim Yun‐Sung , Lim Jun‐Heok , Chun Hai‐Soo 
Published: September 2005

AbstractCreep tests were conducted to measure the creep rates of pure Ni, Ni/7wt%Ni3Al, and Ni/5wt%Ni3Al/5wt%Cr anodes for MCFCs. The resulting creep rates were well modeled by a creep rate equation. During the initial stage of sintering, the creep mechanism was affected by the microstructure, and geometry referred to the macroscopic shapes of the porous anodes. For the Ni/7wt%Ni3Al and Ni/5wt%Ni3Al/5wt%Cr anodes, the creep rate varied nonlinearly with time, obeying a power law with an exponent of n < 1, in contrast to the behavior of high‐density materials, which exhibit linear Nabarro‐Herring or Coble creep when subjected to an applied load. Compared to the pure Ni anode, the anodes containing Ni3Al showed considerably increased creep resistance due to the impeding of mass transport of nickel particles in the anode when it was subjected to a compressive load. Collectively, the present results suggest that Ni/7wt%Ni3Al and Ni/5wt%Ni3Al/5wt%Cr anodes simultaneously have high creep resistance, and thus may represent a viable alternative porous anode for use in MCFC. © 2005 American Institute of Chemical Engineers AIChE J, 2006
Ring chromosome 9 [r(9)(p24q34)]: A report of two cases

Published: September 2005

AbstractWe report clinical and molecular cytogenetic studies in two patients with ring chromosome 9. Cytogenetics and fluorescent in situ hybridization (FISH) analysis using the p16 gene probe on 9p21, the ABL gene on 9q34, chromosome 9 alpha satellite‐centromeric probes, and TelVision 9p and 9q probes which identify subtelomere‐specific sequences on chromosome 9p and 9q, revealed 46,XX,r(9)(p24q34).ish r(9)(305J7‐T7‐,p16+,ABL+, D9S325−) and 46XY,r(9)(p24q34).ish r(9)(305J7‐T7‐,p16+,ABL+, D9S325−). Based on FISH analysis at least 115 kb was deleted on terminal 9p, and at least 95 kb from terminal 9q. In comparison with other reports of r(9), deletion 9p, and deletion 9q, both patients had clinical characteristics of ring 9 and additional features of deletion 9q or deletion 9p syndrome. The variability between the two cases with r(9) despite similar breakpoints identified by GTG‐banding and FISH may be explained by submicroscopic differences between deletion breakpoints, ring instability, interaction of other genes on the phenotype, and variation in fetal environmental conditions. © 2005 Wiley‐Liss, Inc.
Complete trisomy 1q with mosaic Y;1 translocation: A recurrent aneuploidy presenting diagnostic dilemmas
Authors: Scheuerle Angela , Heller Karen , Elder Frederick 
Published: September 2005

AbstractWe present a case of a liveborn male with complete trisomy 1q in mosaic form due to a de novo unbalanced translocation. There are seven previously documented cases of complete trisomy for 1q, which demonstrate that this is a lethal condition. All cases have similar phenotype including weights greater than 50th centile for gestational age, hydrocephalus, microphthalmia, abnormal ears, small mouth or jaw, and abnormal fingers. Single umbilical artery, imperforate anus, and dysplastic kidneys are also seen in more than one patient. Five of the eight translocation cases have identical chromosomal breakpoints involving 1q and Yq. This suggests the possibility of sequence similarities on these two chromosomes as has been documented with several other recurrent chromosomal rearrangements. Further, this case demonstrates the need for postnatal genetics evaluation following prenatal diagnosis. In postnatal testing, the aneuploidy could not be demonstrated in metaphase cells from cultured lymphocytes. More detailed testing prompted by abnormal amniocentesis and neonatal dysmorphology was necessary to confirm the cytogenetic diagnosis. Without the prenatal diagnosis, it is likely that the true cytogenetic aberration would have gone undetected. © 2005 Wiley‐Liss, Inc.

Published: September 2005

AbstractWe report on segmental and full paternal isodisomy for chromosome 14 in three previously unreported Japanese patients. Patient 1 was a $5{\raise0.5ex\hbox{$\scriptstyle 6$}\kern-0.1em/\kern-0.15em\lower0.25ex\hbox{$\scriptstyle {12}$}}$‐year‐old girl, Patient 2 was a male neonate, and Patient 3 was a $6{\raise0.5ex\hbox{$\scriptstyle 7$}\kern-0.1em/\kern-0.15em\lower0.25ex\hbox{$\scriptstyle {12}$}}$‐year‐old girl. Physical examination at birth showed various somatic features characteristic of paternal uniparental disomy for chromosome 14 (upd(14)pat) such as hairy forehead, protruding philtrum, micrognathia, small thorax, and abdominal wall defects in Patients 1–3, and the constellation of somatic features was persistently observed in Patients 1 and 3. Radiological studies at birth delineated unique bell‐shaped thorax with coat‐hanger appearance of the ribs in Patients 1–3, but the thoracic deformity ameliorated in Patients 1 and 3 by mid childhood. Chromosome analysis showed a 46,XX karyotype in Patients 1 and 3 and was not performed in Patient 2. Microsatellite analysis indicated full paternal isodisomy for chromosome 14 in Patients 1 and 2 and segmental paternal isodisomy for chromosome 14 distal to D14S981 at 14q23.3 in Patient 3. Methylation specific PCR assay for the differentially methylated region (DMR) of GTL2 at 14q32 yielded positive products with methylated allele specific primers and no products with unmethylated allele specific primers in Patients 1–3. Since clinical phenotype was similar between Patient 3 with segmental upd(14)pat and Patients 1 and 2 with full upd(14)pat, the results are keeping with the 14q32 localized imprinted genes as the critical components of the phenotype observed in upd(14)pat and help narrow the search for additional genes to the ∼40 Mb region distal to D14S981. Furthermore, it is likely that the characteristic thoracic deformity ameliorates with age. © 2005 Wiley‐Liss, Inc.
