Authors: Mallick Swapan K. , Nahid Gufran K. , Deb Asit R.
Published: May 2023

Objective:

Breast carcinoma is one of the most common cancers in India. Breast cancer is usually associated with serious side effects due to the long-term treatment procedure. This study investigates how to improve the overall quality of life (QoL) of patients in physical, psychological, and social aspects.

Materials and Methods:

Records of patients attending the Radiotherapy Outpatient Department (OPD) from May 2019 to June 2021 were analyzed retrospectively. Records of several patients available in the department were reviewed by the census method, which is based on pre-decided inclusion and exclusion criteria.

Results:

Out of 105 patients included in the study, 38.1% (N=40) of the patients were graduates, and 30.5% (N=32) of the patients were illiterate; 54.3% (N=57) of the patients belong to rural areas. Only 24.8% (N=26) of the patients were employed and the remaining 75.2% (N=79) of the patients were unemployed. However, most of the patients (41.0%) developed grade 1 acute skin toxicity, among which a maximum number of patients (N=47) developed grade1 late skin toxicity. After radiotherapy among all included patients, almost 13.0% of the patients developed arm edema. According to the Hospital Anxiety and Depression Scale score, the maximum abnormal scores for depression were 60.0% (N=63) and for anxiety 59.0% (N= 62).

Conclusion:

This study emphasizes that older women and those from lower socio-economic strata tolerated chemotherapy and radiotherapy better. We can also conclude that improved QoL has been a major concern for breast cancer patients undergoing long-term treatment. In a post-treatment setting, serial evaluation of the QoL not only improves the treatment outcome but can also be a prognostic factor.
Principal component analysis of categorized parameters in periprocedural myocardial injury following percutaneous coronary intervention
Authors: Acharyya Malay , Mondal Tanushree
Published: May 2023

Objective:

The elevation of troponin-T (Trop-T) or creatinine kinase myocardial isoform (CKMB) is very common during the percutaneous coronary intervention (PCI). A study was attempted to determine the correlation between elevated Trop-T or CKMB and the parameters of PCI by using multivariate analysis, especially principal component analysis (PCA).

Materials and Methods:

A prospective observational study was carried out among 100 patients who underwent PCI for stable coronary artery disease in which 31 and 37 patients were found to have elevated Trop-T and CKMB (>3 times) following PCI. The correlation was studied between Trop-T or CKMB (dependent variable) and different parameters, viz., total stent length (mm), fluoroscopy time (min), lesion strength, left ventricular (LV) function, procedural complications, type of lesions, vessels treated with drug eluting stent (DES), and major adverse cardiac events (MACE) as independent variables.

Results:

For Trop-T, the principal component (PC)-1 and PC-2 obtained 63.49% and 30.88% of the original variation. For PC-1 and PC-2, maximum positive loading was recorded for stent length followed by fluoroscopy time and for LV but negative loading for the type of lesion and type of stent (DES vs bare metal stent [BMS]). For CKMB, the PC-1 and PC-2 obtained 61.22% and 32.08% of the original variation. For PC-1 and PC-2, maximum positive loading was recorded for stent length and fluoroscopy time followed by vessel treated but negative loading for the type of stent and MACE, and maximum positive loading recorded for LV function but negative loading for the type of lesion.

Conclusion:

This study indicates which factors are most important in preventing periprocedural myocardial injury during PCI and may be a suitable tool to prevent myocardial injury and for subsequent less MACE and better patient outcomes.

Assessment of glycated hemoglobin levels in non-diabetic subjects with recently diagnosed hypo and hyperthyroidism
Authors: Narayanan Sujesh K. , Pillai Renjith G.
Published: May 2023

Background:

Thyroid disorders are highly prevalent in the general population and generally manifest as hypothyroidism or hyperthyroidism. Glycated hemoglobin (HbA1c) is commonly used for the assessment of the long-term glycemic status of diabetic patients. But the HbA1c concentration not only depends on prime glycemia but some other factors.

Aims and Objectives:

The objective of this study was to measure glycated hemoglobin and thyroid hormone levels and aimed to determine the effects of hypo and hyperthyroidism on glycated hemoglobin in non-diabetic patients.

Materials and Methods:

This case-control study was conducted on 70 euglycemic individuals each newly diagnosed with hypo and hyperthyroidism. Seventy age and gender-matched controls were recruited. Baseline HbA1c was estimated by high-performance liquid chromatography (HPLC) and thyroid status was measured by chemiluminescent immunoassay (CLIA) method in all cases and controls and then compared.

Results:

HbA1c values were found to be significantly higher in the hypothyroid group (P < 0.001), whereby its values in hyperthyroid subjects showed no significant difference from controls (P = 0.17). A positive correlation (r=0.67) exists between the levels of thyroid-stimulating hormone (TSH) and HbA1c in hypothyroid patients, but no significant correlation (r= -0.07) was observed for hyperthyroid subjects.

Conclusion:

HbA1c may not be a reliable indicator of glycemic status in patients with hypothyroidism, and so HbA1c results should be interpreted with caution in such patients.
A case report of skeletal fluorosis leading to cervical compressive myelopathy and a review of literature
Authors: Singhai Abhishek , Mishra Vishnu N. , Ingle Vaibhav
Published: May 2023

Fluorosis is a public health problem that is caused by excess intake of fluoride through ground/deep bore water. It gets deposited in the bones, teeth, and soft tissues. Fluoride in the human body acts as a “double-edged sword.” Fluoride is beneficial in small amounts but toxic in large amounts. People who have consumed 10–20 mg of fluoride per day for more than 10–20 years may develop crippling skeletal fluorosis. Stiffness and pain in the major joints, including the neck, back, hips, and knees, reduce mobility. The bone structure may change and ligaments may calcify in extreme cases, resulting in muscular weakness and pain. Here, we have reported a case of chronic quadriparesis due to compressive cervical myelopathy. After extensive workup, diagnosis of skeletal fluorosis was made.

Authors: Sathishbabu R. , Santhanakrishnan R.
Published: May 2023

The corrugated foam core sandwich construction is used in variety of structural applications. These structures are subjected to flexural, impact, edgewise compression and shear loads. Traditional process for manufacturing of sandwich panel is not suitable for making corrugated core sandwich panel. In this work a novel methodology has been developed for construction of corrugated foam core sandwich panel. The present study focuses on the flexural behaviour of sandwich panel by varying the foam densities and corrugated cell. Two types of densities with one cell and two cells are used. The sandwich employs a Glass Reinforced Polymer (GRP) orthotropic material for both the two outer skins and the inner core web. In particular, the core is designed to have uneven topology to cooperate with GRP skins in membrane and flexural properties by adding a corrugated foam core. At first, a comparison has been performed between different density foams. Initially, 40 kg/m3 with 1 unit cell and 32 kg/m3 with 1 unit cell are compared, and then the same densities are compared with 2 cells. Among all, 40 kg/m3 with two cells shows highest flexural strength compared to the other specimens. Also, the sandwich panel with an empty core has been tested to understand the strength of the face sheet and corrugated core.

Authors: Mogra Ashish , Pandey Pankaj Kumar , Gupta Krishna Kumar
Published: May 2023

In this paper, heat transfer performance is investigated for plain and nanoparticle coated tube-in-tube heat exchangers. Four types of tubes, i.e. bare copper tube, bare aluminium tube, Cu-Al2O3 nanoparticle coated tube and anodized aluminium tubes are used for performing the experimental investigation. The coating thickness of Cu-Al2O3 nanocomposite surface and anodized aluminium tube varies from 10, 25 and 30 micrometres to 15, 20 and 30 micrometres respectively. The surface is found to be hydrophilic in nature as the contact angle changes from 79.82deg to 55.47deg. The prepared surfaces are characterized by FESEM, EDS and FTIR. By adjusting the hot and cold fluids relative mass flow rates, one may calculate not only the overall heat transfer coefficient but also the efficiency of the tube-in-tube heat exchanger. The Cu-Al2O3 nanocomposite coated surface has the highest overall heat transfer coefficient and efficiency, followed by an anodized aluminium surface, bare copper surface and bare aluminium surface. The aluminium anodic oxide (AAO) surface also exhibits an increased heat transfer coefficient, but to a lesser extent than the nanocomposite coating.

Authors: Kaurase Kalpit P. , Singh Dalbir
Published: May 2023

Cellulose is one of the most frequently used and generally available materials on Earth and has been utilized for ages in a variety of applications. Numerous researchers have investigated various lignocellulosic sources for the extraction of cellulose and the author has introduced a new source for the extraction of cellulose and cellulosic nanofibers: fruits or seedpods of Delonix Regia (CNF). The solvent casting process is used to create the PVA/CNF composite after the cellulose and CNF have been removed using a mechano-chemical method. SEM, tensile testing, soil burial testing and moisture absorption tests have all been used to examine the morphological, mechanical, biodegradable and moisture absorption capabilities of pure PVA and PVA/CNF composite with 1, 3, 5, 7 and 9 percentages of CNF. According to SEM findings, agglomeration was seen at higher concentrations but uniform and homogenous distribution of nano-fillers was seen at lower percentages of CNF. It is profusely clear from the results of the tensile tests that the percentage elongation initially decreased and then began to increase at higher concentration, while the Young’s modulus and tensile strength initially increased at lower percentages of CNF rapidly and gradually decreased for higher concentration. Pure PVA had the least resistance to degradation in biodegradability test, while the biodegradability test showed that the inclusion of CNF decreased the composite material’s ability to degrade. With the addition of CNF, the rate of moisture absorption decreased, resulting in a PVA/CNF composite material that will last longer and perform better without material degradation.
An Experimental Study on the Emission Characteristics in CI Engine using Nano Particle Coated Catalytic Converter
Authors: Ramanathan P. , Rajavel R.
Published: May 2023

A proven viable technology to reduce vehicular exhaust gas emission is the catalytic converter. Although catalyst converters are an effective and efficient method to react to certain pollutants, they are expensive due to the use of noble metals like palladium, platinum and rhodium. Various research has been carried out to find a viable alternative to the noble metal catalyst that can react over vehicular pollutants such as oxides of nitrogen (NOx), carbon monoxide (CO), unburnt hydrocarbon (UBHC) and particulate matter (PM) emitted by the combustion of hydrocarbon burnt internal combustion engine. This paper investigates the emission characteristics of a nano-particle-coated catalytic converter in a conventional fossil-fuelled compression ignition engine. The catalyst used in the research is a nano-particle of metal oxides such as aluminium oxide (nano-sized Al2O3) particle and titanium oxide nano-sized (TiO2) particle. This catalyst is less expensive compared to a noble catalyst. Experiments were made on a single cylinder four strokes water-cooled diesel-fuelled compression ignition engine with a catalytic converter coated with alternative nano-particles. The exhaust gas was allowed to pass through the nano-sized catalyst deposited over the honeycomb structure of the substrate of the catalytic converter and the emission was measured using a five-gas analyser. The result showed a decreased level of oxides of nitrogen.

Design and Optimization of Wing Internal Structure to Study the Flutter Frequency of Aircraft Wing
Authors: Akshayraj N. , Ramakumar B.V.N.
Published: May 2023

The field of aviation has reached a lot of milestones in the 19th and early 20th century, but the supersonic commercial flights are still a nightmare in 21st century. The major obstacle to reach this milestone is the effect of flutter, which is an aeroelastic phenomenon. It is very important to understand the effect of flutter to reduce it. In this paper effect of flutter is studied by varying the wing internal structures. A scaled down model of the AGARD 445.6 wing having 65A004 aerofoil is designed using Catia V5, for which the experimental data is available for validation. Grid independence study is carried out to obtain more reliable mesh quality. Since flutter is a transient phenomenon time-step independence study is carried out for the time steps of, 0.005s, 0.0025s and 0.00125s. Since there is no difference between the flutter frequency readings for 0.0025 seconds and 0.00125 seconds, 0.0025 seconds is chosen to reduce the computation time. The baseline case is validated with an experimental data available and an error of 0.2-5.32% is observed. Aircraft wing is mainly made out of aluminium alloys. Hence a suitable aluminium alloy is selected by comparing the flutter frequencies. To choose a suitable material, three materials each from wood, alloys and composite are considered i.e., mahogany, aluminium alloy 7075 T6 and Aluminium Metal Matrix Composite (AMC) which are widely used in the Aviation industry. AMC is considered on the basis of frequency charts whose flutter frequency is 30Hz. In this paper in order to supress the flutter we have introduced optimization of ribs and spars in the wing. Variation in the number of ribs, flange width and rib thickness are considered individually. Wing configuration with 10 ribs, flange width of +10% and 10mm rib thickness respectively are having the best flutter frequencies. The wing with above features is further optimised by keeping weight as a constraint by introducing circular and triangular cut-outs section. Flutter frequency for without cut-out, circular cut-out and triangular cut-out are 77.84 Hz, 78.27Hz and 78.43Hz respectively. Hence it is concluded that ribs with triangular cut-outs can be able to reach maximum flutter frequency.

Authors: Elsie Femina K. , Koilraj M.
Published: May 2023

In the present work, 6 mm plates of Al-Mg alloy AA5083-H321 was friction welded. Weld microstructures, hardness values and tensile properties were evaluated in the welded condition. Macrostructure studies revealed that the shape of the stir zone is a basin-shaped type and it appeared more like a rectangular box and no macroscopic defect or weakly bonded regions were observed in the weld region, which extended through the full thickness of the plates. There were no noticeable changes in the microstructure compared to the respective unaffected base material and there was not much of difference in the microstructures of the nugget and the base metal. The pitting corrosion results indicate that there was noticeable improvement in the pitting potential values of the welds. The weld nugget region exhibited better pitting corrosion resistance compared to other regions. The base material and the friction stir welded materials are far superior in resistance to salt fog corrosion.

Magnesium based alloys are some of the widely used light weight metals in vehicles and aerospace industries, but these materials are having low strength to weight ratio when compared to aluminium. To enhance their strength to weight ratio, some ceramic materials like carbides and oxides of metals are added as reinforcements. In this work, AZ31 magnesium alloy is reinforced with 1%, 2% and 3% of Groundnut Shell Ash particles (GSAp) through powder metallurgy. Micro hardness and compressive strength are studied and the microstructural analysis is also done. The addition of ash particles as reinforcement has not shown much variation in the strength and hardness. The addition of ash particles of more than 3% leads to crack. The addition of ash particles increases the rate of corrosion.

Published: May 2023

It is very advantageous to have a solid grasp of the thermo-elasticity property of the material while designing an automobile brake at an early design stage. To ensure mechanical brakes' longevity and compactness, which are both crucial in this application, it is recommended that the accurate prediction technique of maximum structural stress be employed throughout the design process for mechanical brakes. As a consequence of this research, a practical and dependable analytical approach for the design of mechanical brakes has been developed, which makes use of modelling and analysis methodologies to accomplish its objectives. In this research, the stress analysis of an automobile's brake was carried out, with the purpose of minimising the stress and pressure created in the brake as a result of the vehicle braking. The complete investigation of the brake, as well as the modelling of the brake, will be carried out using the ANSYS software. The CAD software called CATIA will be used to do the clutch analysis. It is envisaged that this effort will also contribute to the creation of the most efficient and dependable mechanical brake design in the future. In this study, we investigate the structural, thermal and wear behaviour aspects of brake shoe liners coated with nano composite coating materials such as ZrO2 to see how they perform.

The results revealed that the blend B25 of the test biodiesel is found optimum, as it recorded better specific fuel consumption and brake thermal efficiency. Further coating on the piston enhanced the performance of the optimum blend when compared with the standard engine.
Strategic Optimization of Post Weld Heat Treatment for Dissimilar TIG Weldment of P22 and P91 Steels
Authors: Singh Bikram Jit , Duppala Azad , Kumar Parmod , Arora Ravish , Bahl Shashi
Published: May 2023

The Gas Tungsten Arc Welding (GTAW) between P22 (2.25Cr-1Mo) and P91 (9Cr-1Mo) steels are quite common in heavy vehicle structures like; railway locomotives and war (or combat) vehicles. After welding, high hardness values of the Heat-Affected Zones (HAZs) of these dissimilar weld joints are possibly obtained. The uneven hardness in HAZ comes from the austenite transformation to Martensite, because of highly uncontrolled cooling rates. The considerable difference in hardness among various zones leads to prior cracking and is bound to failure during high-temperature operations. Therefore, there is a dire need to establish an appropriate Post Weld Heat Treatment (PWHT) to temper the dissimilar weld joints for required durability. The study investigates the microstructure and mechanical properties of various erupted zones of steel, before and after the application of PWHT. Before and after PWHT, weld zone and HAZ in P22 and P91 are mechanically tested and metallurgically examined. Further PWHT is tried to be optimised strategically and statistically, for the least variation in hardness among different zones. So that any failure due to thermal stresses or strains, during normal running conditions can be avoided.

Peran Redaktur Anonim dalam Teologi Kitab Obaja
Authors: Fiah Yusri Lusinda M.
Published: May 2023

An observation of the work of the prophets is not only aimed at their words but at the assumption of secondary editorial additions to the texts. This approach is also supported by indications of the division of texts in this book. In general, the division based on the theme of the text's preaching, namely Obadiah 1:1-15 and 16-21, still seems to overlap in verse 15.  This contradicts the opinion that the material of the book comes from Obadiah, supported by the argument that there is inconsistency with the news of the condemnation of the prophet's oration. In addition, this kitab is still filled with textual problems. The determination of the relationship between the two corridors in the division of textbook is a delicate aspect to establish. This paper displays the authorship and history of the conciliation of the book of Obadiah, as well as its theological applicability to the people moment for several purposes. The first is to trace the authorship of the book of Obaja and the process of assuaging the book to gain theological communication of the book for the people moment. This research will be conducted using logical constructions and interpretation exploration of the texts as part of qualitative research.  Analysis of aspects of interpretation is carried out through critical studies centered on historical methods of redaction. AbstrakPerhatian karya para nabi yang tidak hanya ditujukan pada kata-kata mereka tetapi pada asumsi adanya tambahan-tambahan editorial sekunder terhadap teks-teks. Pendekatan ini didukung pula dengan adanya indikasi pembagian teks-teks pada kitab ini. Secara umum pembagian berdasarkan tema pemberitaan teks yaitu Obaja 1:1-15 dan 16-21 masih terlihat tumpang tindih pada ayat 15. Pendapat ini bertentangan dengan pendapat bahwa materi-materi kitab berasal dari Obaja, didukung oleh argumen yang menyatakan adanya kekonsistenan dengan berita penghukuman dari orasi nabi. Isi materi kitab ini masih dipenuhi dengan persoalan-persoalan tekstual. Penentuan hubungan antara kedua bagian dalam pembagian teks merupakan aspek yang sulit untuk dijalin. Tulisan ini menampilkan kepengarangan dan sejarah peredaksian Kitab Obaja, serta relevansi teologisnya bagi umat sekarang ini. Penelitian yang dilakukan penulis sebagai bagian dari penelitian kualitatif. Sementara analisis aspek-aspek penafsiran dilakukan melalui studi kritis dengan berpusat pada metode sejarah peredaksian.

Pujian yang Membebaskan atau Membelenggu?: Hermeneutik Feminis terhadap Amsal 31:10-31
Authors: Kriswanto Agus , Sianturi Juliana
Published: May 2023

The appreciation to “a virtuous woman” in Proverb 31:10-31 tend to be interpreted by patriarchal perspectives. Such interpretations view a virtuous woman as someone who should benefit man. This article intends to seek a fresh reading of Proverbs 31:10-31 by a feminist perspective. The method used to produce this reading is a feminist hermeneutics approach, which applies three steps of analysis: hermeneutics of suspicion, hermeneutics of remembrance, and hermeneutics of liberation. The result of this research is that the appreciation to women in Proverbs 31:10-31 should not be used as a means to legitimize male domination by shackling women in an ideal image that only benefits men, but rather as a means of remembering the women’s suffering and fighting power, as well as triggering creative efforts for women's liberation so that they can actualize their own potential. AbstrakPujian terhadap “istri yang cakap” di dalam Amsal 31:10-31 cenderung ditafsirkan dari sudut pandang patriakal. Tafsir yang demikian memandang istri yang cakap sebagai perempuan yang seharusnya menguntungkan laki-laki. Tulisan ini bermaksud memberikan pembacaan terhadap Amsal 31:10-31 dari sudut pandang feminis. Metode yang digunakan untuk menghasilkan pembacaan tersebut adalah dengan pendekatan hermeneutik Feminis, yang menerapkan tiga langkah analisis: hermeneutik kecurigaan, hermeneutik ingatan, dan hermeneutik pembebasan. Hasil penelitian ini adalah bahwa pujian terhadap perempuan dalam Amsal 31:10-31 semestinya tidak dijadikan sebagai sarana untuk melegitimasi dominasi laki-laki dengan membelenggu perempuan pada gambaran ideal yang hanya menguntungkan laki-laki, melainkan untuk dijadikan sebagai sarana mengingat derita dan daya juang perempuan serta memicu upaya kreatif untuk pembebasan perempuan agar dapat mengaktualisasikan potensi dirinya sendiri.
