Long Time Stability of Direct Aging GH4169G Alloy Forging Disc after Thermal Exposure at 650°C
Authors: Fu Shu Hong , Li Zhao , Zhang Ya Zhou , Wang Tao
Published: October 2022

An isothermal aging study was carried out on direct aging GH4169G alloy forging disk for up to 10000 hours at 650°C. The evolution of microstructure and mechanical properties of the alloy were systematically studied via scanning electron microscope (SEM), transmission electron microscope (TEM) and physicochemical phase analysis. The results show that the size of main strengthening phases γ′′ and γ′ in GH4169G alloy direct aging disk increases gradually, while their quantity decreases with prolonging aging time. The total amount of γ′′ and γ′ is 14.1% at as-heat treated condition, which decreases by 3.1% at 10000h. The amount of δ phase increases gradually, and the content of δ phase reaches 5.4% at 10000h, which increases nearly twice. The α-Cr phase adjacent to the δ phase on the grain boundaries shows a parabolic increase in its content, and reaches 2.231% at 10000h. The yield strength, stress rupture life shows varying degrees of reductions as prolonging thermal aging time.

Authors: Guo Yuan Yuan , Zhang Mai , Liu Chen Guang , Xu Jian Wei , Zhang Jian , Luo Yu Shi
Published: October 2022

The influence of withdrawal rate (3, 4.5,6,9 and 12 mm/ min) on microstructure and high temperature rupture properties of A3 alloy was investigated by testing the microstructure and properties of the third generation nickel-based single crystal superalloy. The results show that with the increase of withdrawal rate, the dendrite spacing decreased exponentially, the segregation degree of main elements and the content of (γ + γ) eutectic structure decreased, and the size of γ phase decreased. After heat treatment, the eutectic structure was dissolved basically, and the segregation of the forming elements of γ phase is eliminated at different withdrawal rates. The size of γ phase in dendrite is smallest of 372.3μm at 4.5 mm/ min, the pore content is significantly larger than that of as-cast alloy, and decreased firstly and then increased with the increasing of withdrawal rate, which is 0.112% at 4.5 mm/ min and 0.182% at 3 mm/ min. The rupture life of the alloy at 1100 °C/140MPa is the longest at 4.5 mm/ min, which is mainly determined by the precipitation of TCP phase, pore content and γ size.
Research on Fatigue Properties and Fracture Mechanism of δ-TRIP Steel
Authors: Xu Xin , Liu Ren Dong , Su Hong Ying , Lu Yan Peng , Guo Jin Yu
Published: October 2022

In this work, a new type of δ-TRIP steel was designed. The fatigue limit and S-N curve were measured by the fatigue testing machine. The fatigue fracture was observed by the scanning electron microscope (SEM), and influencing factors of fatigue crack initiation were analyzed. The results show that the fatigue limit of δ-TRIP steel is 361MPa, and fatigue cracks are initiated on the surface of the sample. In the initial stage of fatigue crack initiation, the crack growth rate of the specimen is relatively slow under the action of stress. As the crack continues to expand, the magnitude and direction of the stress on the crack tip change and the stress situation becomes more complicated. The crack begins to branch and grows in different directions The metastable retained austenite in δ-TRIP steel undergoes phase transformation under the action of external force, which will absorb a lot of energy. At the same time, there are many large angle grain boundaries in the steel hindering the crack propagation. These two characteristics make the δ-TRIP steel has excellent fatigue performance.
Long Persistent Afterglow Luminescence in Gd3Al3Ga2O12:Ce3+, Green Emitting Aluminate Phosphor
Authors: Yadav Pooja J.
Published: October 2022

Green LL is observed in Ce doped Gd3Al5O12: Ce, Ga garnet phosphors. LL is well correlated with Ce3+ emission and a peak around 150°C in the TL glow curve. In comparison with the commercial phosphor YAG, the Gd3Al5O12: Ce, Ga (GAG) is more stable and shows more intense TL properties, this phosphor can be used for dosimetry detections and measurements. Gd3Al5O12 activated with Ce (0.7 mol.%) phosphors were prepared by combustion synthesis. The long-lasting luminescence (LL) is also reported in Pr3+ and Ce3+ doped in reducing atmosphere in YAG phosphor. But YAG: Ce gives yellow emission which doesn’t suit LL applications. On the other hand, Ga substituted GdAG: Ce phosphor gives green emission at shorter wavelengths. In this paper we explored Ga substituted GdAG: Ce phosphor prepared by combustion synthesis for LL, results of these investigations are reported in this paper.

Authors: Li Chun Lin , Xiao Liang , Li Lin , Xin Xu , Zhang Rui Kun , Liu Ren Dong
Published: October 2022

The mechanical properties and microstructure evolution of a one step quenching and partitioning steel containing bainite/martensite/retained austenite mixed microstructure was studied though static and dynamic tensile tests (strain rates ranging from10-3 s-1 to 5×102 s-1 ).Scanning electron microscopy (SEM) and electron-back-scattered diffraction (EBSD) were applied to describe the microstructure evolution near the fracture. XRD characterization shows the volume fraction of retained austenite decrease exponentially with the strain rates increased.EBSD phase maps reveal that the first type of retained austenite is less sensitive to strain rate than the second type.

Authors: Yau Shamsudeen , Adamu Ya′u , Wongsawat Pramote , Songthap Archin
Published: October 2022

Background:

Despite substantial progress in the fight against human immunodeficiency virus and acquired immunodeficiency syndrome globally, it remains a threat to global adolescent health. This study assessed the level of HIV knowledge among vocational school students and identified the relevant factors.

Methods:

This was an analytical cross-sectional study conducted from August to September 2019. A total of 345 students aged 15 to 19 years were selected from three vocational schools in Phitsanulok Province, Thailand, using a multistage random sampling technique. The HIV Knowledge Questionnaire (18 item version) was used to collect the data, which were analysed by mean, frequency, Chi- square and binary logistic regression.

Results:

Only 38.8% of participants were fully aware of HIV knowledge; five individual items showed a significant difference in knowledge of HIV between males and females; two items relating to HIV prevention knowledge (P=0.021, 0.009); two items relating HIV transmission (P=0.028, 0.035); one item relating to HIV diagnosis (P=0.008). Factors that were significantly associated with HIV knowledge included gender (male vs. female, OR 1.83, 95% CI 1.01-3.34), residence (sub-district municipality area vs. sub-district of administrative organization area, OR 0.44, 95% CI 0.23-0.84), education (2nd and 3rd academic year vs. 1st, OR 7.00, 95% CI 2.40-20.41; OR 6.40, 95% CI 2.05-20.01) and source of income (from both parents vs. self, OR 0.07, 95% CI 0.04-0.64).

Conclusions:

There are serious deficits and disparities in the knowledge of male and female adolescents on HIV transmission, prevention and diagnosis, and there is a need to expand the provision of gender-focused sexual health education programs.
Helicobacter pylori infection in a multi-ethnic population in east coast of Borneo, Malaysia
Authors: Lee Ooi-Cheng , Lai Chung-Ket
Published: October 2022

Objective:

To determine the prevalence of Helicobacter (H.) pylori infection among the population of east coast of Borneo and explore the relationship between demographic factors, ethnicity and risk of H. pylori infection.

Methods:

This cross-sectional study enrolled 211 patients who underwent elective oesophagogastroduodenoscopy in 2017. Demographic data, endoscopic indications as well as the results of the mucosal biopsy were obtained and analysed from the endoscopy unit registry.

Results:

A total of 211 patients from 14 ethnic groups were enrolled in the study, most of were Chinese (28.4%), followed by Dusun (14.7%) and Songgai (13.7%). Overall, the period prevalence for 2017 was 44.5%. Multivariate logistic regression analysis showed an association between ethnicity and H. pylori. Bajau (adjusted odds ratio=5.612, P=0.005) and Dusun ethnic groups (adjusted odds ratio=7.359, P=0.001) were at a significantly higher risk of H. pylori infection compared to Chinese. However, the regression model only explained 11.6% (Cox & Snell Pseudo R2) of the prevalence of H. pylori infection.

Conclusions:

The period prevalence for 2017 was 44.5%, with certain indigenous ethnic groups having a higher risk than others. Clinicians should consider obtaining further history regarding the ethnic's culture and dietary practice prior to starting H. pylori eradication therapy.

Authors: Li Yifan , Guo Cheng , Wu Qin , Guo Zhongmin
Published: October 2022

Objective:

To review the characteristic of Coronavirus disease 2019 (COVID-19) outbreaks in mainland China, particularly post-Wuhan outbreaks, and to help design effective responses in the foreseeable future.

Method:

The data regarding COVID-19 outbreaks between December 2019 and March 16, 2022 were obtained from China's publicly available databases. The data were analyzed using descriptive statistics. Five outbreak stages were defined according to distinct epidemiological characteristics across different time periods over the past two years.

Result:

Since the 2020 Wuhan outbreak, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) local infections were confirmed in 37 995 cases as of March 16, 2022. We identified 285 isolated outbreaks in unrelated people that occurred in four additional distinct stages, over 57% of which had been imported, such as imported infected travelers and fomite transmission. The basic reproduction number (R0) of original SARS-CoV-2 was about 2.79, while the Delta variant was about 5.08 and Omicron was 7.0 or greater, resulting in the disease being more contagious during the fourth (Delta) and fifth (Omicron) stages than previous stages.

Conclusion:

China has experienced various COVID-19 outbreaks of different levels since the start of the pandemic in Wuhan, and local transmission is mainly caused by imported sources. If the “dynamic COVID-zero” policy is not appropriately followed, it will be difficult to contain the spread in China from overseas and to cope with the Omicron variant.

Published: October 2022

Background:

There is a high frequency of recurrent, chronic, and therapy-resistant dermatophyte infections reported from India.

Objectives

The study was carried out to identify the epidemiologic factors, clinical features, and causative agents associated with therapy-resistant tinea corporis.

Subjects and Methods

Patients above 18 years of age, diagnosed by dermatologists, and received systemic therapy for at least 3 weeks with inadequate response or relapsed within 4 weeks of cessation of therapy were taken for the study. Demography, clinical features, and results of mycological examination were retrieved.

Results

A total of 64 (33.7%) patients were included after screening 190 patients. There were 33 (51.6%) males and 31 (48.4%) females, and most patients (51, 79.7%) were young adults (18–45 years). Family history was obtained in 50 (78.1%) patients. Tinea cruris was associated in 50 (78. 1%) and tinea faciei in 15 (23.4%) of cases. Topical corticosteroids were used by 46 (71.87%) patients in the past. The past therapy with oral itraconazole (46 cases, 56.25%) was the most common to be used. Comorbidities were found in 7 (10.9%) patients. Trichophyton mentagrophytes in 55 cases (85. 9%) was the most common isolate followed by Trichophyton rubrum (7, 10.9%) cases associated with therapy-resistant tinea corporis.

Conclusion

Therapeutic failure is alarmingly common in the current scenario of dermatophytosis in India. Failure is probably seen with all common isolates but the most common among T. mentagrophytes. Younger patients, high contagious nature, and concomitant tinea faciei may be associated with a higher risk of therapy resistance.

Published: October 2022

INTRODUCTION

The Catholic Men Organisation (CMO) is one of the four major organisations in the Church, the others being Catholic Women Organisation (CWO), Nigerian Federation of Catholic Students (NFCS) and Holy Childhood Association. The CMO is the pillar of the Church and as its motto, “Christ is our Leader” provides exemplary leadership in the Church. Members of the CMO are heads of their various families and understand the need to plan for every member of the family. Since 2006 when the first International father’s Day celebration took place in St Paul, children and students have played a key role. They have entertained the Parish with traditional dance displays, and had essay-writing competitions in 2007 and 2021. In addition, three undergraduate students enjoyed scholarship awards in 2021. Of course, the focus on students and children is not surprising since St. Paul is a predominantly student parish otherwise usually referred to as the Wisdom Parish.

Published: October 2022

The overarching purpose of this study was to explore teacher views on some issues that hinder quality in teaching and learning at a TVET college. This is explored by considering challenges that face teachers in providing quality teaching and learning. A total of twenty-four lecturers participated in the study. The study adopts a mixed methods approach and enacts Karl Maton` Legitimation Code Theory (LCT) as its analytical framework. Data were collected by means of interviews, questionnaires, and document analysis. While a symbiotic relationship is expected to exist between expertise and decision-making structure in the technical and vocational education and training (TVET), there is a dichotomous gap in the two domains, which in turn compromises the quality of teaching and learning.
Comparison of the expression of GATA-3 protein from the transcription factor family and pathological prognostic parameters in invasive ductal carcinomas of the breast
Authors: PARLAK Leymune , KANDEMİR Olcay
Published: October 2022

Background GATA binding protein 3 (GATA-3) is one of the six transcription factor family members and is important for glandular development in the breast. Its expression becomes important in breast cancer. We aimed to compare GATA-3 immunoreactivity and pathological prognostic factors in patients with invasive ductal carcinoma.

Material and Methods Our study was conducted retrospectively with 300 breast invasive ductal carcinoma patients who were operated on in our hospital between May 2013 and June 2014. Patient reports, slides and blocks in the pathology archive were scanned. GATA-3 immunohistochemical (IHC) staining was evaluated according to the nuclear staining, intensity and percentage. The relationship between clinicopathological prognostic parameters and GATA-3 IHC staining results was investigated.

Results A positive staining was observed in 286 (95.3%) cases. According to the GATA-3 staining intensity and percentage, 210 (70%) cases stained strongly and 246 (82%) stained +4, respectively. There was a significant relationship between GATA-3 immunoreactivity with ER, PR, Cerb-B2, Ki-67, mitotic degree, mitotic count and histological grade.

Conclusions There was a correlation between the high expression of GATA-3 and good prognostic markers. Hormone receptors can be evaluated with Cerb-B2 and Ki-67 and used as prognosis determinants in breast cancers. They can be used to identify both primary and secondary breast tumors.

Published: October 2022

Background Fulfilling diagnostic criteria of hemophagocytic lymphohistiocytosis (HLH) is challenging due to unavailable laboratory tests. Hence, we aimed to reveal malignancy-associated-HLH (M-HLH) patients in our center, which can not be reached in all tests.

Material and Methods Nine patients with M-HLH were analyzed retrospectively.

Results The median age was 59 years. The distribution of the underlying diseases was like diffuse large B cell lymphoma in 3 patients, acute myeloid leukemia in 2 patients, Hodgkin lymphoma in 2 patients, T cell non-Hodgkin lymphoma in 1 patient, and small cell lung cancer in 1 patient. According to HLH-2004 diagnostic criteria except for soluble CD25 and natural killer activity tests; one patient had 3/6, six patients had 5/6, two patients had 6/6 criteria while the median H-score was 258 at diagnosis. According to Tamamyan et al’s criteria; at the diagnosis, all patients had ≥7 (between 7-12) of 18 parameters. Patients fulfilled ≥5 parameters a median of 15 days (3-52 days) before the diagnosis and on that time six patients had 3/6 criteria of HLH-2004. 88.8% of the patients died. The median duration of survival was 8.5 days (1-18 days).

Conclusions Unavailability of the tests in some countries and centers as in ours results in complications to fulfill 5 of 8 criteria and being delayed in diagnosis and treatment. We need to develop more specific and accessible criteria, and grading systems for M-HLH diagnose.

Background This study aimed to analyze patients who apply to emergency services and need palliative care regarding appropriate patient care and effective use of health institutions.

Materials and Methods The study was conducted prospectively on patients who applied to the emergency services of Bursa Uludag University Health Application and Research Center, Health Sciences University Bursa Yüksek Ihtisas Training and Research Hospital and Bursa City Hospital between 15.08.2021 and 15.02.2022 and needed palliative care.

Results A total of 261 patients, 143 male (54.8%) and 118 female (45.2%), were included in the study. It was determined that 50 (19.1%) of these patients had previously received palliative care services. It was determined that the patients included in the study applied to the emergency services 7.52±6.77 times in the last year. The three most common diseases diagnosed in patients admitted to the emergency department were pneumonia (24.5%), urinary system infection (7.7%), and cerebrovascular disease (5.4%). Of the patients, 39.84% were referred/hospitalized, 25.28% were referred/hospitalized to intensive care units, 2.68% refused treatment, 2.68% died, and 29.5% have been discharged.

Conclusion As a result, it is understood that most of the patients in need of palliative care do not receive this service, and patients who can be treated in palliative care units are treated in clinics and intensive care units.

Synthesis of Linear Antenna Arrays with Physics Based AOA, CryStAl and LA Algorithms
Authors: DURMUŞ Ali , YILDIRIM Zafer
Published: October 2022

In this article, 10, 16, and 24-Element of Linear Antenna Arrays (LAAs) synthesis are carried out with 3 different novel physics-based metaheuristic methods. These methods are called Archimedes Optimization Algorithm (AOA), Crystal Structure Algorithm (CryStAl), and Lichtenberg Algorithm (LA). In order to prevent electromagnetic interference from other systems operating in the same frequency band, the Sidelobe Level (SLL) of the radiation patterns of the LAA has been suppressed as much as possible. While performing the LAA synthesis, Half Power Beam Width (HPBW), which is related to the directivity of the antenna, is also taken into account. The methods proposed in this study are run independently 30 times to obtain the statistical values of LAA synthesis. The minimum, maximum, median, and standard deviation values of the SLL and HPBW of the radiation patterns obtained as a result of these runs are tabulated. The performances of these three proposed novel physics-based optimization methods are given comparatively. In all simulation studies, the CryStAl method generally showed the best performance.
Investigation of the Sample Disturbance Effects on Consolidation Parameters Obtained from Conventional Oedometer Tests
Authors: DUMANLILAR Muharrem , FENER Mustafa , BALCI Mehmet Can
Published: October 2022

This study explores the effects of sample disturbance on the compression curves obtained from oedometer tests and the inferred effective preconsolidation stress (sp'). The samples were systematically disturbed by removing different fractions of the soil ranging from 10%, 20%, 30%, 40%, and 50% and remolding them back into place to reach the same initial void ratio. It was found that when the rate of disturbance was increased, it became more difficult to determine the sp' values on the compression curve; the typical bending point on the compression curve became increasingly indistinct, and negligible changes occurred in the sp' values of the disturbed soil samples up to a disturbance rate of 40%. If the soil samples whose consolidation parameters such as preconsolidation stress can’t be determined are subjected to disturbances greater than 40%, it is recommended that no consolidation parameter of such samples be specified.

Authors: BAŞTEMUR KAYA Ceren , KAYA Ebubekir
Published: October 2022

Kelebek optimizasyon algoritması, kelebeklerin yiyecek arama davranışını modelleyen güncel meta-sezgisel algoritmalardan biridir. Pek çok problemin çözümünde başarılı bir şekilde kullanıldığı literatürde görülmektedir. Bir meta sezgisel algoritmanın başarısını, kontrol parametreleri ve problem boyutu doğrudan etkilemektedir. Muhtemel problemler değerlendirildiğinde, bazıları düşük boyutlu iken, bazıları yüksek boyutlu olabilmektedir. Bununla birlikte, meta-sezgisel algoritmaların yüksek boyutlu problemler üzerinde de başarılı olması beklenmektedir. Bu çalışmada, yüksek boyutlu nümerik optimizasyon problemlerinin çözümünde kelebek optimizasyon algoritmasının performansı değerlendirilmiştir. Kelebek optimizasyon algoritması; yapay arı koloni algoritması, armoni arama algoritması ve çiçek tozlaşma algoritması ile karşılaştırılmıştır. Sonuçların anlamlılığının analizi için Wilcoxon işaretli sıralar testi uygulanmıştır. Sonuçlar, çok boyutlu nümerik optimizasyon problemlerinin çözümünde, kelebek optimizasyon algoritmasının diğer algoritmalardan genel olarak daha başarılı olduğunu göstermiştir.
Branquidade e controle do não-branco: análise de materiais didáticos e contornos indígenas no Brasil ao longo da década de 1930
Authors: Araujo Carvalho Yuri , Cardoso de Mello Rafael , Lastoria Andrea Coelho , Souza Sérgio Luiz de
Published: October 2022

O presente artigo debruça-se sobre distintas elaborações discursivas atinentes ao elemento indígena brasileiro (inserido, por sua vez, no período histórico colonial), presentes no material didático intitulado “Rudimentos de História do Brasil: curso primário”, elaborado por João Ribeiro de Andrade Fernandes e empregado no ensino escolar nacional ao longo de boa parte do século XX. Nossos esforços baseiam-se na hipótese segundo a qual relevantes distorções, omissões e simplificações a respeito dos mundos indígenas – presentes nas intersecções entre os campos religioso, econômico, social, cultural, cotidiano, entre outros, e orientadas, via de regra, por sentidos nuclear e aprioristicamente negativos – encontravam-se presentes em materiais didáticos editados e manejados nos ambientes escolares brasileiros, catalisando – ainda que potencialmente – introjeções de aversão aos “outros” (no caso, as etnias e os sujeitos históricos indígenas brasileiros), contrapondo-os à naturalização da “branquidade” enquanto padrão estruturalmente aceito de civilidade. Os métodos mobilizados ao longo do artigo dialogam com a análise qualitativa dos discursos contidos no referido material didático.

Published: October 2022

The objective of this work is to design and implement decentralized adaptive controllers in order to perform the position control of two links of an electromechanical manipulator robot with five degrees of freedom (DOF 5). The manipulator robot is consisted of five rotational joints, four links and a claw. Five DC motors are used to drive the robot and the motion transmission from the motors  to the joints is achieved by gear trains. Models of the manipulators robots are obtained using Newton-Euler or  Lagrange equations; and are coupled and nonlinear. In this work, the model of the links of the manipulator robot is obtained in real time for each sampling period. The parameters of the links to be controlled are identified by recursive least squares (RLS) method, according to data from the links, and  are used in the designs of adaptive controllers for the positions control of the joints of the links under analysis. In the end, the experimental results are presented, like the evaluation of the performance achieved by the manipulator robot links.

TERÖRİZMİN TANIMLANMASI SORUNU BAĞLAMINDA BİRLEŞMİŞ MİLLETLER GÜVENLİK KONSEYİ’NİN ULUSLARARASI TERÖRİZME KARŞI MÜCADELEDEKİ ROLÜ
Authors: KIŞLA Selcen Nur
Published: October 2022

Terörizmin varlığı eskiye dayanmakla birlikte uluslararası toplumun ve Birleşmiş Milletler’in gündemine gerçekten taşınması 11 Eylül saldırıları ile olmuştur. Bu olaylardan sonra Birleşmiş Milletler, uluslararası terörizmin her türünü uluslararası barış ve güvenliğe tehdit olarak kabul etmiştir. Dolayısıyla, uluslararası barış ve güvenliğin sağlanmasında birincil yetkili organ olan Birleşmiş Milletler Güvenlik Konseyi'nin yeri bu konuda ayrı bir önem taşır. Bu maksatla makalede, Birleşmiş Milletler Güvenlik Konseyi’nin uluslararası terörizm ile mücadeledeki rolü çalışma konusu olarak seçilmiştir. Ancak, Birleşmiş Milletler organları, terörizm kavramını tanımlamaktan imtina etmektedir. Bu tanımlamayı üye olan devletlere bırakmaktadır. Birleşmiş Milletler üyesi devletler ise terörizme karşı ortak bir yaklaşım sergileyememektedir. Dolayısıyla, terörizm ile mücadeleye ilişkin kararların etkinliğinin sağlanmasının önünde, terörizmin tanımlanması sorunu önemli bir engel teşkil etmektedir. Bu kapsamda makalede öncelikle, terörizmin tanımlanması sorunu ve Birleşmiş Milletler’in terörizme ilişkin genel yaklaşımı incelenmiştir. Daha sonrasında ise Birleşmiş Milletler Güvenlik Konseyi’nin terörizm ile mücadeledeki rolü, kararlar ve komiteler bağlamında tanım sorunu merkezinde incelenmiştir.
