Objective: Three simple, sensitive, accurate, and precise spectrophotometric methods have been developed and validated for the determination of Alzheimer’s disease drug memantine HCl (MEM) in pure form and pharmaceutical formulations.
Methods: The method was based on the formation of charge transfer complex between MEM as n-electron donor and various π-acceptors quinalizarin (Quinz) in methanol, p-chloranilic acid (p-CA) and 7,7,8,8-tetracyanoquinodimethane (TCNQ) in acetonitrile as chromogenic reagents which showed an absorption maximum at 558, 532 and 840 nm using Quinz, p-CA and TCNQ, respectively. The optimization of the reaction conditions such as the type of solvent, reagent concentration and reaction time were investigated.
Results: Under the optimum conditions, beer’s law is obeyed in the concentration ranges 4.0–24, 10–160 and 5.0–50 μg/mlusing Quinz, p-CA and TCNQ, respectively with good correlation coefficient (r2 ≥ 0.9995) and with a relative standard deviation (RSD% ≤ 1.11). For more accurate analysis, Ringbom optimum concentration ranges were found to be between 8.0–20, 15–140 and 10–45 μg/ml using Quinz, p-CA and TCNQ, respectively. The limits of detection were found to be 1.2, 2.70 and 1.45 µg/ml and the limits of quantification were found to be 4.0, 9.0 and 4.83 µg/ml for Quinz, p-CA and TCNQ, respectively. A Job's plot of the absorbance versus the molar ratio of MEM to each of the acceptors under consideration indicated (1:1) ratio.
Conclusion: The methods were successfully applied to the determination of MEM in its pharmaceutical formulations and the validity assessed by applying the standard addition technique. Results obtained by the proposed methods for the pure MEM and commercial tablets agreed well with those obtained by the reported method.

Authors: Tao Ming , Luo Hao , Wu Chengqing , Cao Wenzhuo , Zhao Rui
Published: March 2022

The complex boundary of the elliptical inclusion rendered it difficult
to solve the problem of wave scattering. In this study, the steady-state
response was analyzed using the wave function expansion method.
Subsequently, the Ricker wavelet was employed as the transient
disturbance and Fourier transform was used to determine the distribution
of transient dynamic stress concentration around the elliptical
inclusion. The effects of wave number, elliptical axial ratio and
difference in material properties on the distribution of the dynamic
stress concentration around the elliptical inclusion were evaluated. The
numerical results revealed that the dynamic stress concentration always
appeared at both ends of the major axis and minor axis of the elliptical
inclusion, and the difference in material properties between the
inclusion and medium influenced the variations in the dynamic stress
concentration factor with the wave number and elliptical axial ratio.

Prediction of Distant Recurrence in Breast Cancer using a Deep Neural Network
Authors: Azman B. , Hussain S. , Azmi N. , Ghani M. , Norlen N.
Published: March 2022

Breast cancer is the most common cancer diagnosed in women, and it is ranked as the second highest cancer with high mortality rate. Breast-cancer recurrence is the cancerous tumor that returned after treatment. Cancer treatments such as radiotherapy are performed mainly to kill cancer cells; however, some cells may have survived and multiply themselves at the same area as the original cancer (local recurrence) or to any other part (distant recurrence). Distant recurrence occurs when cancer cells spread to other parts of the body, most commonly to bone, breast, liver, and lungs. This study employed an Artificial Neural Network of the deep learning approach to predict distant recurrence of breast cancer. Factors that contribute to the risk of recurrence are age, type of surgery performed, tumor size, breast subtype, estrogen receptor, progesterone receptor, undergoing chemotherapy or not, and lymph node involvement. The actual value of distant recurrence is also considered to be a variable. Principal Component Analysis using five and three principal components was conducted. The outcome indicates that the model has accuracy of up to 0.80 using three principal components.
A method for the robustness evaluation of cable-stayed bridges with steel truss girders under different reinforcement cases
Authors: Zheng X. , Luo Z. , Zhang Y. , Wang S. , Ren L.
Published: March 2022

Structural robustness, an index for structural geometrical agreement, is used to assess the alternative load paths of structures subjected to loads. Therefore, robustness can be extended to evaluate the robustness of bridges with local failure in individual members. In this work, a method that includes the use of a radar chart is proposed to assess the robustness of cable-stayed bridges by considering the mechanical performance of bridges with local failure in the cables and chords. Four plans regarding the truss girder and cables are designed to reinforce a damaged bridge. The results indicate that these two alternative path plans disperse the stress in the members in the truss girder, and the reduction of alternative path plan 2 (AP2) is greater than that of alternative path plan 1 (AP1). Similarly, the two plans regarding the cables are found to decrease the vertical displacement of the truss girder under gravity, and the reduction of the first plan is slightly greater than that of the second plan. Consequently, the two alternative load path plans improve the indexes of the truss girder, leading to an increase in the value of IRob to 0.74. Moreover, regarding the truss girder, the two alternative cable plans are used to increase the indexes, and the values are all found to be larger than the corresponding values of the intact cable-stayed bridge. The proposed method including the use of a radar chart, which is associated with several indexes, can be used to assess the structural robustness of intact and damaged bridges, thereby allowing for the development of reinforcement plans.

Published: March 2022

Biosynthesis of nanosilver by using sweet orange (C. sinensis) as a bioreductor has shown nanosized results. In this research, the effect of volume variation of sweet orange juice and peel extract combination toward the characteristics and antibacterial activity of synthesized nanosilver will be studied. Solution of AgNO3 1 mM was mixed with a combination of sweet orange juice – peel extract with ratios (v/v), 3:0; 1.5:1.5; 1:2; 0.5:2.5 and 0:3 at 60˚C for 45 minutes. The color change of the mixed solution indicated the formation of nanosilver and confirmed by using UV/Vis spectrophotometer and TEM analysis. The results show that the addition of sweet orange juice in combination accelerated the color change of the mixed solution. The characterization of nanosilver with UV/Vis spectrophotometer confirmed SPR peak at 438-459 nm. The stability test showed that nanosilver reduced with sweet orange juice-peel extract 0,5:2,5 (v/v) was stable and had inhibition diameter tested by the diffusion method against S.aureus (19.50 mm) and S.epidermidis (18.09 mm), indicates a moderate inhibition. Its TEM analysis confirmed the particle's size of about 30-56 nm with spherical form.Keywords: nanosilver, biosynthesis, Citrus sinensis, characteristic, antibacterial activity
Identitas Moral sebagai Moderator Pengaruh antara Moral Disengagement dengan Kecurangan
Authors: Septiana Eva , Hakim Ishaq Mahmudil
Published: March 2022

Kecurangan merupakan fenomena negatif yang terjadi di berbagai konteks. Penelitian ini bertujuan untuk menemukan apakah kecurangan dapat dipengaruhi oleh moral disengagement dan pengaruh tersebut dapat dimoderasi oleh identitas moral. Sebanyak 213 orang mahasiswa dari 7 universitas di Indonesia mengikuti penelitian ini. Peneliti mengukur kecurangan dengan Tugas Matriks Angka yang pernah digunakan oleh Bloodgood, Turnley, dan Mudrack (2008); Gino, Ayal, dan Ariely (2009). Moral disengagement diukur menggunakan adaptasi dari Moral Disengagement Scale yang dirancang oleh Detert, Treviño, dan Sweitzer (2008). Identitas moral diukur dengan adaptasi dari Moral Identity Questionnaire yang dikembangkan Black dan Reynolds (2016). Penelitian ini menemukan bahwa tidak terdapat pengaruh signifikan moral disengagement terhadap kecurangan (odds ratio = 1,111; n = 213; p 0,05; two-tailed). Peneliti menduga salah satu penyebab hasil tidak terdapat pengaruh signifikan moral disengagement terhadap kecurangan karena variabel moral disengagement sangat bergantung pada variabel lain. Lebih lanjut, identitas moral tidak memoderasi pengaruh moral disengagement terhadap kecurangan (odds ratio = -1,140; p 0,05; two-tailed). Hasil ini diduga karena adanya dampak dari peran yang dijalani oleh partisipan. Pada penelitian ini, ada kemungkinan partisipan menganggap dirinya menjalani peran sebagai mahasiswa sehingga mereka tidak melakukan kecurangan. Kesimpulannya tinggi rendahnya tingkat moral disengagement seseorang tidak berdampak pada tingkat kecurangan yang terjadi. Sementara itu, hasil analisis interaksi antara moral disengagement dan identitas moral tidak menunjukkan pengaruh yang signifikan. Dengan kata lain, identitas moral tidak memoderasi pengaruh moral disengagement terhadap kecurangan. Perlu dilakukannya konstruksi alat ukur moral disengagement dan identitas moral pada situasi dan konteks yang diinginkan untuk meningkatkan ketepatan data.

Teaching English Writing at the Secondary Level in Vietnam: Policy Intentions and Classroom Practice
Authors: Chi Nguyen Thi Kim
Published: March 2022

The need for writing is undoubtedly pervasive in our lives, especially in modern societies of the 21st century. When examining the everyday world, one finds people engaged in many varieties of writing such as sending a text message, writing a covering letter or a scholarship application form, composing a research paper, etc. In short, writing not only is an integral part of our social and professional activities but also determines our life chances. The growth of English as a lingua franca makes English writing more important than ever before, which results in more attention paid to teaching English writing in non-English speaking contexts. This paper reports on part of the findings of a study that investigated practices of teaching English writing at the lower secondary level in Ba Ria-Vung Tau, Vietnam. The research employed a qualitative, multi-case study approach. The findings revealed a significant gap between the English education policies of the Vietnamese government and classroom practice. The teaching of secondary English writing did not prepare learners well for the 21st century language skills as expected.

Published: March 2022

A study of the core criticality during the draining process of liquid fuel salt on Molten Salt Fast Reactor (MSFR) was done. Two accident scenario that causes the draining process were loss of freeze valve coolant and loss of secondary coolant. This study used basic design of the MSFR with the salt fuel compositions of LiF (77.5%) â€“ ThF4 (19.985%) â€“ 233UF4 (2.515%). The criticality calculation has been analyzed from the value of the effective multiplication factor obtained from Open MC (Monte Carlo base) calculation. The effective multiplication factor was calculated with a variation on the number of freeze valves open; 1, 8, and 16 valves. The calculation has resulted in the value of effective multiplication factor decreasing exponentially during the draining process. Results from this study could be used as basic for the future study of the accident condition in MSFR, since there are still many MSRs accident scenarios that still haven't been taken into account.
