Capacitor Discharge Spot Welding of Aluminum, Part 2: Electrode Life Assessments
Authors:   American Welding Society, GOULD JERRY E. , LINDAMOOD LINDSEY , MALPICA JULIO , LESTER PATRICK , ZHU DEWEI
Published: January 2022

A major challenge for high-volume resistance spot welding of aluminum sheet is durability of the electrodes themselves. In production today, electrodes have total anticipated lives (including dressing) on the order of 1000 welds. This is largely related to the use of medium-frequency direct current (MFDC) power. The single-polarity orientation of MFDC welding results in excessive heating of one electrode (anode) and accelerated wear rates. Recently, technology employing capacitor discharge (CD) welding in conjunction with polarity switching has been developed. This work is the first effort in examining the response of resistance spot welding on aluminum sheet using this power source. Part 1 of this research (Ref. 1) described basic process robustness in spot welding with CD power systems. Part 2 addresses electrode life response. Duplicate electrode life tests were completed for 2000 welds without failure. These results were related to the polarity switching and short time that produced balanced and minimized wear. Additional testing was done without the use of electrode-cooling water. A limited test (500 welds) largely paralleled the ones done with cooling, suggesting that long-term spot welding with polarity-switching CD power and no water was possible.

Published: January 2022

The computational design of industrially relevant welded structures is extremely time consuming due to coupled physics and high nonlinearity. Previously, most welding distortion and residual stress simulations have been limited to small coupons and reduced order (from three-dimensional [3D] to two-dimensional [2D]), or inherent strain approximations were used for large structures. In this current study, an explicit finite element code based on a graphics processing unit was utilized to perform 3D transient thermomechanical simulation of structural components during welding. Laser brazing of aluminum alloy panels as representative of automotive manufacturing scenarios was simulated to predict out-of-plane distortion under different clamping conditions. The predicted deformation pattern and magnitude were validated by laser scanning data of physical assemblies. In addition, the code was used to investigate residual stresses developed during multipass arc welding of a nuclear industry pressurizer surge nozzle and subsequent welding repair where a 3D simulation was necessary. Taking the experimental data as reference, the 3D model predicted better residual stress distribution than a typical 2D asymmetrical model. Stress evolution in welding repair was also presented and discussed in this study. The efficient numerical model made it feasible to use integrated computational welding engineering to simulate welding processes for large-scale structures.

Published: January 2022

The teacher’s attitude towards mathematics teaching is seen as an essential factor in forming students’ attitudes towards mathematics. However, no one has extensively described the reflection of teachers’ self-confidence in teaching mathematics, especially for novice primary teachers. Therefore, the purpose of this study sought to describe a reflection of the self-confidence attitude of novice primary teachers in teaching mathematics. A questionnaire based on novice primary teachers’ teaching experience was administered to a total of 28 novice primary teachers (N = 22 males, N = 6 females) conveniently selected to participate in the study reported in this article. The semi-structured interviews data explored novice primary teachers’ reflections on the given questionnaire scale items. The qualitative data obtained from semi-structured interviews informed the quantitative information extracted from the questionnaires. The results showed that the reflection of the self-confidence attitude of novice primary teachers in low, moderate, and high participants on the scale of confidence in teaching mathematics raises three essential findings, specifically (1) ability on content knowledge, (2) ability to explain, and (3) ability in classroom management. The resulting reflection in low, moderate, and high participants on the scale was an attitude toward success in teaching mathematics, namely, the appraisal of others, and on the scale, the usefulness of mathematics teaching, namely the ability to understand the usefulness of mathematics.

Published: January 2022

Indonesian students are indicated to have a low math efficacy. Currently, no psychology scale has been created to measure the math efficacy of Indonesian students, especially for junior high school level students. This study aims to develop a math efficacy scale for junior high school level students or equivalent based on Indonesian students’ characteristics. The study used an exploratory sequential design with mixed methods. The results of qualitative analysis through focused group interviews on two small groups of eight students show that seven major themes were related to mathematics efficacy. Qualitative analysis as the basis for a scale development consisting of 33 items and is administered to 478 participants. The results of the quantitative analysis through validity test with Principal Component Analysis (PCA) shows that four dimensions appeared with total variance explained reaching 60.4%. The model was re-tested for compatibility with Confirmatory Factor Analysis (CFA) and obtained index values of p < 0.001 (χ2), 0.047 (SRMR), 0.907 (TLI), 0.918 (CFI), and 0.064 (RMSEA). The four dimensions have met the standard of a fit index with 23 items remaining. The validity test was also supported by Pearson's Product Moment correlation of 0.795 for convergent validity test with Math Attitude Scale (MAS) and divergent validity test of -0.331 with Mathematical Self-Efficacy and Anxiety Questionnaire (MSEAQ). The scale's reliability was very good, with Cronbach's alpha value of 0.918.

Published: January 2022

Slow learners also carry out the implementation of online learning at inclusive elementary schools. Online learning conditions are different from face-to-face learning, and it becomes a challenge for teachers to deliver mathematics learning for slow learner students. Learning mathematics is a learning that is considered difficult by slow learner students. It is because slow learner students have limited cognitive abilities and understanding of symbols, abstracts, and concepts. This study aimed to determine the obstacles in the implementation of mathematics learning, which includes the planning, implementation, and assessment stages for slow learner students at inclusive elementary schools. This research is qualitative research with a descriptive approach, and the subjects were ten inclusive elementary school class teachers in Sleman. The data were collected by interview and analyzed with the help of Atlas.ti software. Based on the analysis results, teachers experienced barriers in implementing online learning. The teacher experienced barriers in planning learning media and limited learning resources specifically for slow learner students at the planning stage. The most significant barriers come from the students' condition at the implementation stage, and another barrier comes from parents and teachers. Furthermore, the barriers in the assessment stage included the limitations of distance and time, the validity of the answers, student independence, and decreased enthusiasm of students for working.

Published: January 2022

One of the competencies for mathematics teachers that needs to be developed continuously is professional competence. However, even if efforts for developing teachers’ competencies have been made formally by the government, it seems still lacking. This study, therefore, aims to develop mathematics teacher professional competencies through an informal development model using social media. This research used a qualitative method, a case study design, involving 19 mathematics teachers from various regions in Indonesia in the informal development process in the range of 2019-2021. The informal approach was carried out using question-and-answer techniques and guided discussions on mathematical problems. From the teacher development processes, 30 mathematics problems and their solutions were collected. As an illustration of this development process, this article presents five problems and their solutions, including solutions for two mathematics problems on conceptual understanding and three mathematics problems on problem-solving. We conclude that this informal approach is fruitful in helping mathematics teachers solve mathematics problems. This study implies that the teacher development process carried out in this study can be used as a model for informal teacher development by other higher education academics in their respective places.

Published: January 2022

This study was aimed at evaluating the effect of Parkia biglobosa seed on dexamethasone-treated pregnant rats. Locust bean seeds were purchased from an open market in Ado Ekiti, Nigeria. It was processed and ground into powder which was subsequently used in formulating feed for experimental animals. Fifteen female pregnant rats were divided in three groups of five each. Animals in group A were exposed to standard animal feed only. This served as the control group. Those in group B were exposed to animal feed mixed with locust beans + 0.3 mg/kg body weight of dexamethasone, while those in group C were exposed to animal feed mixed with locust beans. At the end of eight days treatment, animals were sacrificed and blood sample was collected into EDTA bottles and centrifuged. Plasma was separated and used for the determination of glucose and lipid profile. Exposure of animals to dexamethasone was observed to significantly (p<0.05) increased the concentration of plasma glucose concentration when compared with the control as well as animals treated with P. biglobosa only. Animals treated with dexamethasone along with P. biglobosa were observed to have higher concentrations of triglyceride, total cholesterol, low density lipoprotein (LDL) and very low density lipoprotein (VLDL) when compared with those in animals in the control group as well as those treated with P. biglobosa only. Observations from this study revealed that dexamethasone adversely perturbed and unhinged plasma glucose and lipid profile in female pregnant rats while P. biglobosa-formulated diet was observed to be a potent hypoglycemic and hypolipidemic agent.

The production cost is one of the issues for some complex ceramics applications, like the superconducting oxides. The main properties of such materials, i.e., zero electrical resistivity and perfect diamagnetism, make them attractive for several applications, including energy storage. Thus, in this work, we focus on the production and structural characterization of BSCCO superconducting films using a domestic inkjet printer. The precursor solution was prepared following Pechini's method, and it was used, such as the ink. Then, an E-shape film was printed over a SiO2 substrate. The results show that the sample produced with 12 depositions presented a superconducting transition at 81 K and a critical current density of 9.68 A/cm2 at 78 K.

Published: January 2022

Utilization of wind energy is one option to produce electrical energy in the form of wind turbines. Wind energy is also renewable energy that can be utilized because of the potential for wind energy in Indonesia with an average wind speed of 2- 6 m/s. The purpose of this performance analysis is to obtain high efficiency so that the S2091 taperless blade can rotate at relatively low Indonesian wind speeds. Airfoil S2091 has an optimal Cl/Cd value to produce 500 W of power. This performance analysis uses the Blade Element Momentum (BEM) method in which the blade is divided into several elements, starting from determining the radius, chord, and twist on the blade. The assumed parameters will be simulated using Qblade v0.96 software and designing 3D blade designs using SolidWorks software. The dimensions of the taperless blade with the S2091 airfoil have a radius of 0.8 m, a chord of 0.12 m, a twist angle of 6.96o - 9.96o, and a maximum Cp value of 47% at a TSR of 4.5. At a speed of 12 m/s the maximum power generated is 998 W when the angular speed of the blade is 645 rpm and the minimum power generated is 95 W. Then the average power generated is 640.94 W. The results of field tests have a maximum charging power of 138 .46 W and an average charging of 14.13 W. Then the power obtained is 257.80 Wh. From these data, the efficiency of the blade system is 30%–40% and the efficiency of field testing is 34.16%.

Published: January 2022

Abstract. Development of modern arthroplasty in Ukraine, according to Academician of the National Academy of Sciences and the National Academy of Medical Sciences of Ukraine O.O. Korzh, began thanks to the activities of O.Ye. Loskutov (Dnipro) who managed to create his own Ukrainian endoprosthesis on the basis of the relevant enterprises of the city and establish specialized endoprosthetic clinic. The article reflects 30 years of experience in the de velopment of national arthroplasty. To solve the problem of development of national arthroplasty, the Orthopedic Joint Replacement initiative program (ORTEN) has been developed. For this purpose, an intersectoral problem laboratory was created which united the efforts of the scientists of different specialties and key enterprises of the Dnipro region. Biomechanical researches on native studying of mechanical properties of articular sites of bones have been carried out through mathematical modeling. Estimation of a stress-strain state of subchondral, spongy bone and various sites of long bones in "bone-implant" system has been carried out in order to define primary and secondary stability of different kinds of the developed im plants. Numerous biochemical, histochemical and toxicological studies on laboratory animals have been performed to evaluate the effects of implant materials and the developed types of protective coatings. X-ray morphometric and anthropometric studies of articular surfaces of bones were used in various pathologies of the joints for the development of implants; technical methods were used to assess the mechanical properties of implants under load. The developed designs of endoprostheses have passed certification and have been brought into pro duction. Clinical introduction of domestic endoprostheses was implemented in the Ukraine’s first specialized department of joint arthroplasty which was opened in Dnipro. The developed methods and methodological support for the use of the elaborated designs of endoprostheses allowed to organize the basic training of Ukrainian specialists through the Basic Course of Prof. O.Ye. Loskutov which was taken by almost 350 Ukrainian orthopedists.

Materials and methods. The results of treatment of 8 patients with chronic wounds and diabetes mellitus (DM) type 2 and stage IV chronic ischemia of the lower extremities by Fontaine were analyzed, in 2 cases there was a combination of venous and arterial insufficiency. Revascularization of the lower extremities was performed through open (2), endovascular (4) and hybrid surgery (2). In case of venous insufficiency, sclerotherapy of perforator veins was performed.

After surgical treatment of the purulent focus, specific bacteriophages were used (after microflora identification). Hydrogel dressings were applied daily, alongside with transplantation of 5,000,000 mesenchymal stem cells (MSC) (CD73+, CD90+, CD105+ and CD45-, CD34-, CD14-, CD79-) by injection into muscle tissue around the wound, then the wound surface was closed with hMSC-fibroblast matrix.

Results. After the closure of the wound surface with fibroblast matrix, the patients noted the disappearance of the pain syndrome. The surface area of the wounds averaged 91.3 ± 30.42 cm 2 before the start of treatment, 89.8 ± 34.21 cm 2 on day 5 and – 73.95 ± 21.2 cm 2 on day 12. Spontaneous epithelialization was achieved in the period from 35 to 141 days (depending on the initial state of the wounds). The average hospital stay was 22.6 ± 2.4 days.

Discussion. It is known that human epithelial cells (hECs) and human mesenchymal stem cells (hMSCs) suppress proliferation, production of inflammatory cytokines and differentiation of T cells. At the same time, they stimulate the formation of regulatory T cells (Tregs). Soluble factors secreted by hECs, including PGE2, TGF-β, Fas-L, AFP, MIF, TRAIL and HLA-G, block differentiation of dendritic cells and M1 macrophages and promote differentiation of monocytes into the anti-inflammatory M2 phenotype. Moreover, hECs and hMSCs are known to be responsible for modulating the host immune system, mainly by suppressing TNF-α, IFN-γ, MCP-1 and IL-6 and increasing the level of anti-inflammatory cytokines. In vitro and in vivo results show increased cell migration and epithelialization leading to accelerated wound healing.
The Diagnosis of Brain Death
Authors: Gritsenko S. M.
Published: January 2022

Organ transplantation is impossible without donation which is performed both intra vitam and posthumously. Each case of multi-organ collection provides help to 4 to 6 patients. We believe that presentation of modern algorithms for diagnosing brain death is quite feasible, and such information can be useful not only for anesthesiologists, but also for doctors of other specialties. This paper presents materials related to organ donation. Diagnostic criteria for human brain death, as well as the procedure for ascertaining human brain death and the actions of doctors of healthcare institutions in relation to persons who are in these institutions and who have clinical indications for the diagnosis of brain death, are determined by "The procedure for cancellation of active measures to maintain the patient's life…". Active measures (ventilation, infusion therapy and vasopressor support, etc.) to support the patient's life are cancelled after the patient's brain death is ascertained, except for cases where the deceased person is considered a potential donor. Verification of the human brain death is carried out by the case management team of the healthcare institution involving, if necessary, members of consultative and diagnostic mobile team, specialists of other healthcare institutions. The head of the healthcare institution is responsible for timely and proper engagement and work of the case management team. The responsible person determines the membership of the case management team by making an appropriate entry in the case record and is responsible for its work.

An anesthesiologist and a neurologist (neurosurgeon) who have at least 5 years of practical experience in the specialty are engaged in the case management team to ascertain brain death in persons over 18 years of age.

Physicians involved in the removal of human anatomical materials and transplantation thereof, as well as transplant coordinator, may not be included in the case management team.

Low GATA3 expression distinguishes basal-like human breast cancer.
Authors: Mamoor Shahan
Published: January 2022

Patients diagnosed with basal-like breast cancer face a more aggressive disease course and more dismal prognosis than patients diagnosed with luminal A and luminal B breast cancer molecular subtypes (1-4). We mined published microarray data (5, 6) to understand in an unbiased fashion the most distinguishing transcriptional features of tumors from patients with basal or basal-like subtype breast cancer. We observed transcriptome-wide differential expression of the transcription factor GATA3 when comparing tumors of patients with basal-like breast cancer with that of other PAM50 molecular subtypes. GATA3 mRNA was present at significantly reduced quantities in the tumors of patients with basal-like breast cancer. Analysis of patient survival data revealed that GATA3 primary tumor expression was correlated with distant metastasis-free survival, with low GATA3 expression correlated with inferior survival outcomes. Low GATA3 expression appears to distinguish basal-like human breast cancer from the other molecular subtypes.

Indonesian is the identity of all Indonesian citizens. Language itself is very important for human life. With language, we can communicate with one another, considering that humans are social creatures who cannot live without each other's help. However, the use of language should not be underestimated. The use and pronunciation must be properly understood so that there are no misunderstandings or other unwanted things. The development of the times and globalization have affected the existence of languages that are currently starting to lose their authenticity. One example is the use of slang as a daily word until the authenticity (original word) is slowly forgotten. As well as the use of foreign languages that are more attractive to the millennial generation. The lack of interest of the younger generation in learning linguistic rules is also one of the factors in changing the existence of Indonesian. The background of the research is about the existence of language, especially Indonesian to the changing era. The purpose of writing this paper is to show the public, especially the millennial generation the importance of maintaining the existence of linguistic rules. Because as good citizens we must maintain and preserve our national identity.
