Published: March 2023

Background: Autoimmune hemolytic anemia (AIHA) is an immune hemolytic disease characterized by hemolysis and anemia which results from increased red cell destruction due to auto antibodies directed against self-antigens on red cells. Clinical characteristics and potential associated hemolysis in AIHA can greatly depend on the serological characteristics.
Aims and Objectives: This study was done to find out the association of Grade of polyspecific Direct Antiglobulin test (DAT), complement involvement and immunoglobulin G (IgG) subclass with severity of hemolysis in an AIHA patients.
Materials and Methods: This was a cross-sectional study conducted for a period of 18 months from March 1, 2012, to August 31, 2013. Fifty consecutive AIHA patients diagnosed by a positive DAT in EDTA anticoagulated blood samples using poly specific anti human globulin reagent were followed up and results of various immunohematological tests such as polyspecific and monospecific DAT, IgG subtyping, and thermal amplitude were performed. Hematological and biochemical parameters such as hemoglobin, percentage of reticulocyte, total serum bilirubin, and serum lactate dehydrogenase also were recorded. Data were analyzed using SPSS v17.
Results: Majority of patients were belonging to 31–40 year age group and there was a remarkable female predilection. Secondary AIHA was more common (56%) than primary. SLE was identified as the most common underlying disorder in secondary AIHA. Majority (46%) were Grade 4 DAT positive. Predominant autoantibody identified was IgG (52%). Of the total IgG positive cases, IgG1 was the predominant subclass. C3d alone was detected in 18% of cases and C3d and IgG together in 30%. About 48% of our patients were of warm type, 32% mixed type, and 20% cold type. About 80% of the study population were treated with steroids alone. A small percentage of cases (16%) needed immunosuppressant in addition to steroids and still a smaller percentage (4%) needed splenectomy. Higher grades of DAT positivity were associated with more severe degree of anemia and hyperbilirubinemia. The study also demonstrated a positive correlation between DAT grade and severity of hemolysis.
Conclusion: AIHA patients in this study were predominantly of Warm AIHA with more of IgG1 involvement. A significant association is found between higher grades of DAT results and severity of anemia and jaundice in this study group. A positive correlation exists between grades of DCT and hemolysis as well.

Authors: Bharti Aditi , Akanksha Tomar  , Tiwari Rajesh
Published: March 2023

Background: There has been delay evident in diagnosing the drug resistance and non-initiation of appropriate treatment based on drug susceptibility pattern resulting in poor treatment outcome of drug-resistant tuberculosis (DR-TB).
Aims and Objectives: The aims of this study were to examine the treatment outcomes for DR-TB patients following universal drug susceptibility testing (UDST) and to examine the association of sociodemographic, behavioral factors, or comorbidities with outcome.
Materials and Methods: A retrospective study at a nodal DR-TB center was done for the past 2 years (2018–2019) following the district’s adoption of UDST. The study comprised patients registered between January 2018 and December 2019. Transferred out cases were excluded from the analysis. Cured or treatment completed were assigned as successful, whereas the treatment failed, lost to follow-up or died were adverse treatment outcome.
Results: A total of 201 patients were initiated on suitable DOTS regime and they continued the treatment from the center, during the study period. Altogether 129 (64.2%) patients had successful treatment outcome. None of the examined variable (age, sex, SES, Body mass index, and comorbidity) is found to have statistically significant association with outcome (P>0.05).
Conclusion: The UDST may be the reason for success rate shown here, higher than in literature published. Although a better stance is possible only by comparing the treatment outcome of pre- and post-uptake of UDST from same setting.
A comparative study of laparoscopic cholecystectomy with and without abdominal drain
Authors: Soubhik Sarkar  , Shib Shankar Kuiri  , Yadhu Rajan  , Kanchan Kundu
Published: March 2023

Background: Laparoscopic cholecystectomy (LC) has been considered the Gold-standard for the management of benign gallbladder disease. With increasing surgeon experience and advancement of instrumentations and equipment, LC is approaching continuously toward a more safe and less invasive technique. There is a consensus that drainage should not be considered mandatory or standard after elective LC.
Aims and Objectives: The aims of this study were to assess the effectiveness of the LC without abdominal drain over sub hepatic drainage and to compare the post-operative outcome between two groups.
Materials and Methods: A descriptive observational comparison study has been carried out in the department of General Surgery BSMCH, from September 1, to December 1, in 130 patients undergoing elective LC. Patients have been divided into two groups: Comparison group and study group after proper matching. Data have been collected via interview, clinical examination, and scrutinizing relevant medical records. Each patient has been followed up after operation. Data have been summarized for estimating various parameters such as mean duration of surgery and hospital stay between the groups and proportion of patient complaining of pain 24 h after surgery.
Results: The mean duration of surgery in drainage group is 108 min which is significantly more than the non-drainage group 88 min. In this present study, the patients with abdominal drain are showing more incidence of post-operative nausea and vomiting (PONV) 21.53% compared to no-drain group 6.15%. In this study, 35.38% of patients with subhepatic drain developed pain after surgery, whereas only 12.3% of the patients with no drain experienced the same. Overall six patients from the drain group still had significant subhepatic collection and eight patients with no drain have the same. The mean duration of stay in hospital of the drain group is 4.06 days, whereas, in no-drain group, it is 2.26.
Conclusion: An uncomplicated gallstone disease can be treated by LC without need for drain with reasonable safety by an experienced surgeon. Hence, no use of drain scores over use of drain in terms of PONV, post-operative pain, and therefore, there is less use of analgesics and also short duration of hospital stay. When a dry operative field is achieved during LC the drain insertion may be avoided.

Published: March 2023

Background: Etomidate is considered as an excellent drug for induction in anesthesia, although it has an undesirable side effect like myoclonus.
Aims and Objectives: The aims of this study were to compare the effect between pre-treatment with nalbuphine and dexmedetomidine for attenuation and severity of etomidate induced myoclonus and to assess their adverse drug reaction.
Materials and Methods: A prospective, randomized, and single-blinded study was conducted on patients undergoing elective surgery under general anesthesia. After selection of patients according to inclusion/exclusion criteria, nalbuphine (0.2 mg/kg) and dexmedetomidine (0.5 μg/kg) were infused 10 min before the induction of anesthesia. The vital parameters and any incidences of myoclonus during operation were observed at fixed interval.
Results: A total of 102 patients in the age group of 18–60 years of either sex were assessed. In Group D 7, out of 51 patients (13.7%) were found to have myoclonus, whereas, in Group N, it was observed in 21 out of 51 patients (41.2%). Difference between the two was found to be statistically significant (P<0.001). In Group D, grade 3 myoclonus was observed in 0% patients. About 2% patients had grade 2 and 11.8% had grade 3 myoclonus. In Group N, grade 3, 2, and 1 myoclonus was recorded as 3.9%, 11.8%, and 25.5%, respectively. The difference between the two groups is statistically significant (P<0.001).
Conclusion: Incidence and severity of etomidate induced myoclonus were less in patients who received pre-treatment with dexmedetomidine than those who underwent pre-treatment with nalbuphine. Furthermore, more hemodynamic stability was achieved with use of dexmedetomidine as the agent for pre-treatment.

Published: March 2023

Background: Fiber optic intubation has become an integral part in management of anticipated difficult airways. Various anesthetic drugs have been used to assist awake fiber optic intubation (AFOI) for producing conscious sedation to provide a calm, cooperative, and responsive patient without respiratory depression for successful awake fibre optic intubation.
Aims and Objectives: The aim of the present study was to compare the efficacy of dexmedetomidine and magnesium sulfate during awake fiber optic orotracheal intubation in patients scheduled for cervical spine surgeries.
Materials and Methods: A randomized, prospective, and comparative study design was conducted in 60 patients in JAH group of hospitals. All patients were randomly divided into two groups: Group A (n=30) patients received dexmedetomidine (1 μg/kg) and Group B (n=30) patients received magnesium sulfate (40 mg/kg) in 100 ml normal saline over 10 min. The fiber optic orotracheal intubation was performed and primary outcome was level of sedation assessed using Ramsay sedation score. Other parameters of study included cough score and intubation score to compare intubating conditions. The secondary outcomes of study included variations in hemodynamic parameters heart rate, systolic blood pressure, diastolic blood pressure, mean arterial pressure, and SPO2 during drug infusion at 2-min interval, immediately after intubation and every 10 min after intubation till 30 min.
Results: Group A (Dexmedetomidine) had better sedation score, cough score, and intubation score with stable hemodynamic variables than Group B (Magnesium Sulphate) with statistically significant results.
Conclusion: Patients receiving dexmedetomidine had better sedation providing more optimum conditions for AFOI with stable hemodynamic parameters and lesser adverse effects during the procedure than magnesium sulfate.

Published: March 2023

Background: Hemorrhoids are one of the most common afflictions of human beings from times immemorial. It is said that 40% of population have symptoms due to hemorrhoids at some time in their lives. Stapled hemorrhoidopexy under local anesthesia has been emerging as the procedure of choice for symptomatic hemorrhoids.
Aims and Objectives: The objectives of the study are as follows: (1) To assess the advantage of performing stapled hemorrhoidopexy under local pudendal block. (2) To study the post-operative complications after stapled hemorrhoidopexy. (3) To assess the feasibility of stapled hemorrhoidopexy in grade IV hemorrhoids. (4) To assess the advantages of stapled hemorrhoidopexy in anal skin regression after surgery.
Materials and Methods: 50 patients of grade 4 hemorrhoids were operated by hemorrhoid stapler under local anesthesia.
Results: Stapled hemorrhoidopexy under local anesthesia can be safely performed as a day care procedure in grade IV hemorrhoids. Patients following stapled hemorrhoidopexy under local anesthesia have reduced post-operative pain, hospital stay, analgesic requirements, and earlier return to work, early mobility out of bed, less operative time, short learning curve, less operative complications, cost effectiveness, and good patient satisfaction.
Conclusion: Stapled hemorrhoidopexy under local anesthesia is feasible to be used in those patients who are unwilling and unfit for other modes of anesthesia with better results with lesser complication rate and as a day care procedure.

Authors: Leesa Misra  , Mahesh Kumar Sethi  , Manash Ranjan Sahoo  , Preeti Kumari Gond  , Kallol Kumar Das Poddar
Published: March 2023

Background: Laparoscopic right hemicolectomy for the right-side colon cancer is well-established and proven to be better than the open approach in terms of post-operative and overall hospital stay. Laparoscopic right hemicolectomy can be done by lateral to medial approach (LA), medial to lateral approach (MA), or tunnel/IRETA approach (TA). No previous study has been conducted to compare the clinical outcomes of all three approaches and the superiority of one approach over the other is still debatable.
Aims and Objectives: This retrospective study was conducted to compare all three approaches and to find the ideal one to practice.
Materials and Methods: This is a retrospective cohort study carried out to analyze 86 patients who were admitted to the department of General Surgery from March 2015 to December 2021 with a diagnosis of the right-side colon cancer and underwent laparoscopic right hemicolectomy with either of these three approaches. A total of 29 patients had operated with lateral to medial approach (LA), 29 patients with medial approach (MA), and 28 with tunnel (TA) approach. The patient’s baseline demographics, perioperative parameters, and post-operative outcomes were compared.
Results: Intraoperative blood loss was significantly lower in the medial to lateral approach and tunnel approach. Duration of surgery was less in the medial to lateral approach as compared to the other two approaches and was statistically significant. R0 resection, lymph node dissection, intraoperative and post-operative complications, morbidity, mortality, and conversion to open were similar in all three groups.
Conclusion: Laparoscopic medial to lateral to medial to lateral approach is feasible and safe and should be preferred approaches in laparoscopic right hemicolectomy.

Authors: Maitra Sanjay , Angel Ivy Toppo  , Suchitra Pal  , Bhabani Chanda Maitra  , Mandal Mohanchandra
Published: March 2023

Background: Early prediction of severity of acute pancreatitis (AP) is important for management of AP patients with escalation of care and aggressive therapy which can reduce complications. Bedside index of severity in AP (BISAP) score is helpful in early diagnosis of severe AP. D-dimer, a biomarker of secondary fibrinolysis may be helpful in predicting the severity of pancreatitis.
Aims and Objectives: The objective of this study was to evaluate the two scoring systems - the BISAP score and D-dimer in early prediction (within 24 h) on the severity of AP and to analyze how D-dimer correlates with BISAP score.
Materials and Methods: Seventy-five patients, aged 18–70 years, suffering from AP due to any cause were included for this prospective, observational study. Within 24 h of admission D-dimer was estimated and BISAP score was calculated. The severity was assessed based on D-dimer level and BISAP scoring systems within 24 h of hospital admission and data were tabulated for analysis. The D-dimer level >2.5 mg/L was considered to be suggestive of severe pancreatitis. The BISAP score >2 in first 24 h was defined as predictive of severe pancreatitis. Spearman rank correlation was used for an analysis of the association between two set of data (BISAP scores and d-dimer levels) and thus to measure the strength and direction of the relationship between the two variables.
Results: In the present study, 37.3% of the patients had D-dimer ≤2.5 mg/L and 62.7% had D-dimer>2.5 mg/L’ on calculating the Pearson’s correlation on the ranked values of the data (BISAP scores and D-dimer levels), the correlation coefficient (Spearman’s Rho, designated as “rs”) was found to be 0.406 which indicates about moderate positive correlation.
Conclusion: D-dimer testing can be used as an alternative test to predict the severity of AP. It shows a moderate correlation with BISAP scoring.

Published: March 2023

Background: One of the most prevalent head-and-neck tumors in Southeast Asia is nasopharyngeal carcinoma (NPC). Each year, NPC causes 84,400 new cases and 51,600 fatalities worldwide. Intensity-modulated radiation therapy (IMRT), which has good local control and few side effects on healthy tissue, is being used to treat NPC.
Aims and Objectives: Our study aims to assess the feasibility of cochlear sparing using volumetric-modulated arc therapy/IMRT technique.
Materials and Methods: Radiotherapy plans of 20 patients diagnosed with NPC who received curative concurrent chemoradiation (Weekly Cisplatin dose of 40 mg/m2) with RT dose of 66 −70 Gy at 1.8–2 Gy/# to a total of 33–35# delivered using True beam LINAC between the year 2020 and 2022 were analyzed retrospectively.
Results: Cochlea sparing reoptimization led to a considerable reduction in radiation dose for both cochleae as compared to the original treatment plans. The median D mean and D max for the left and right cochlea was found to be decreased. The difference in planning target volume (PTV)-D mean between the original and reoptimized plans was negligible. After reoptimization, the median PTV CI remained unchanged. The sparing of the left and right parotids and brain stem was not improved by reoptimization. A similar event was noted for the spinal cord, where the change from the median D max was not statistically significant.
Conclusion: Our investigation showed that a much-increased cochlea sparing is possible in the majority of patients while maintaining PTV dosage coverage and the other organs at risk. Clinical trials in the future, both retrospective and prospective, should examine the effects of this optimization.

Published: February 2023

Groundwater served as the major source of water for existing biophysical species in an ecosystem. In recent years, depletion of the level of groundwater becomes an emerging serious environmental issue due to the anti-reciprocal man and human activities such as global climate change. This study aims to examine the groundwater potential areas using the semi-qualitative research design, based on Analytic Hierarchy Process. The focused is based on the Geographic Information System for the analysis of determining factors, such as distance from the stream and river, precipitation, pond frequency, normalized difference water index, land-use/land cover, drainage density, slope gradient, soil, and topographic wetness index. The Receiver Operating Characteristics were used to check the accuracy of the final calculated map of the groundwater potential zone. The 5 points Likert scale ranges very poor (1) to very high (5) used to analyse the groundwater potential zones. The result shows that 0.81 percent area is very poor for the potentiality of groundwater in the study area. Other scale contained 8.13 for poor, moderate (19.94%), high (39.72%) and very high potential zones (31.41%). The Receiver Operating Characteristics result showed that under the curve success rate is 0.64% and the prediction rate is 0.76%. This result shows a reliable degree of predictability of groundwater near the spatial distribution of marshes, lakes, and water bodies in the study area. The finding shows that the very high potentiality of groundwater areas are determining by the factors of precipitation, pond frequency, distance from river and stream, drainage density, land-use/land cover, soil, and slope in the study area. The result of this empirical analysis can be applied to analyze sustainable and effective water resources management activities.

Published: March 2023

The vehicle Black Box system records variations in vehicles in order to minimize and analyze accidents; or records traffic rules violations automatically and reports them to the traffic authority system. In many countries (like Iraq) traffic violation recording implemented manually causing false traffic fine recordings, even when the vehicle is not at the same location at traffic fine recording, so it is necessary to develop such systems that confirm the availability of the vehicle in that location during violation occurrence. In this paper, a Vehicle Black Box system based 433MHz long-range wireless modulation technology developed for safe driving issues by utilizing gas and flames sensors, and for false traffic violation recording issues by proofing the availability of the vehicle at traffic violation location by utilizing a GPS module. The system-based Internet of Vehicles model transmits the acquired data, where two nodes representing vehicles used with one base station form Vehicle-to-Infrastructure communication mode. The system was tested in real-time and the sensed data was transmitted and stored in a database for future analyzing purposes where the acquired GPS data was used as proof of the vehicle’s correct location with date and time stamps. Two vehicle data where captured and stored indicating their correct location with date and time stamps and stored in a database at the base station. The measured Received Signal Strength indicator and Signal-to-Noise ratio values are stored for analyzing purposes. The performance of the system in such Internet of Vehicle environment is discussed according to the readings.

Authors:   National Economics University, Tran Van Nam , Tran Van Hai ,   University of Social Sciences and Humanities, Vietnam National University, Hanoi, Nguyen Quang Huy ,   Vision and Associates Co., Ltd
Published: March 2023

An invention is a form of intangible asset. When approached from an economic perspective, an intangible asset is a term used to refer to non-physical resources and has value for patent holders. Therefore, determining the value of an invention is an important step in the commercialisation of intangible assets such as technology transfer, capital contribution to businesses, etc. Vietnam has promulgated a system of legal documents on the valuation of intangible assets, but there is no separate regulation on determining the value of inventions, so in practice, it has encountered certain limitations in the application of these legal provisions. This article analyses the limitations of Vietnamese law on determining the value of inventions and proposes solutions to overcome them.

Authors: Andriyani Fitri
Published: March 2023

Abuse and neglect are increasingly occurring in various regions, including in Indonesia. The diversity of abuse and neglect in childhood and adolescence have an impact on neurobiological function damage so that it has long-term impacts on individuals who experience it. Unfortunately, in Indonesia there is no screening tool to assess the trauma of abuse and neglect in childhood and adolescence. This study aims to translate and obtain psychometric property of the Childhood Trauma Questionnaire (CTQ-SF) consisting of physical, emotional and sexual violence as well as physical and emotional neglect dimensions. The translation shows that the Indonesian version of the CTQ-SF has a good level of equivalence with the CTQ-SF. In addition, the classical test theory approach showed that the Indonesian version of CTQ-SF had a high reliability by the need of reviewing of the three items on the sexual abuse dan physical neglect dimensions. Nevertheless, a multidimensional approach of confirmatory factor analysis showed that the Indonesian version of CTQ-SF model was fit to measure the level of maltreatment (abuse and neglect) experience among adolescents in Indonesia

The purpose of the article related to public involvement in budget disclosure, known as participatory budgeting, shows more in terms of the opportunities and challenges faced by a decentralized country, where actors in it participate in making decisions through budgeting formulation. This issue is focused on budget transparency not only to encourage public involvement, but public involvement is very necessary for budget transparency. However, this public engagement has its challenges and benefits. This analysis is carried out through literature studies, journals, and related publications. The data were collected through SCOPUS a qualitative. This study concludes that there are several challenges that need to be considered in implementing public involvement in budgeting. Overly complex budgets and inadequate knowledge make this public disinterest a challenge. A conflict occurs when many groups with different interests take part in it. Public involvement is supported because it can increase tax revenue collection and satisfaction in public services and other benefits for social welfare. The results of this analysis will show several challenges and opportunities that use public involvement to be successful in budget formulation so that reforms in the budget can be carried out and can be used as a model for other regions and can become a system of reform in budgeting.

This has an impact on the majority of residents using dug wells to meet their daily water needs; the occurrence of changes in employment opportunities, namely working as coal extraction in the Kemumu River and changes in work patterns from farming to coal collectors in the river; public health also declines such as the emergence of skin diseases; as well as the accumulation of community disillusionment that has been buried for a long time, which can lead to acts of violence. The results of this study conclude that there are four impacts of the company on people's lives which include the impact of the physical environment, socio-economic, public health and socio-psychological conditions of the community.
Good Governance and Terrorism in Nigeria
Authors: Hakeem Olatunji Tijani
Published: March 2023

Nigeria has been fighting a war against terrorism for long time. It is uncertain if the war can be won because it has been exacerbated by lack of good governance. People have been deprived of economic opportunities, they are socially insecure and politically docile. This has had dire consequences for their human emancipation, which good governance attempts to build. Terrorism has found convenient marketability among the people as failure of the state in good governance has meant easy recruitment for terrorist activities. Therefore, for the war to be effectively prosecuted and won, sources of impediments to good governance need to be identified and addressed squarely. In other words, the curtailment of terrorism in Nigeria is hinged on abilities of the Nigerian state to promote good governance. Presently, Nigeria has been bedeviled with the twinning tragicness of terrorism and lack of good governance, the two signify failure for the state.  Dishearteningly, today, Nigeria is on the verge of becoming a failed state because of its failure in good governance, Nigeria has continually witnessed decline in indicators of good governance. It has become incapable to provide security to citizens as acts of terrorism, banditry and kidnapping have been aggravated in the country.

This study attempts to evaluate the extent of the relationship between small, micro and medium enterprises (MSMEs) and the banking sector in executing economic development strategies in the Covid-19 epidemic era. A qualitative method using a case study approach is utilized to see the link between MSMEs and the banking sector in this study. The research was done in Palembang City with informants from Rural Banks (BPR), Palembang City Government, and MSME actors who issued loans to BPRs. This study indicates that there is a good interaction between BPR, Palembang City Government, and MSME actors in executing economic development strategies in the era of the Covid-19 pandemic. The assistance given by BPR and the City Government can allow MSMEs to tackle numerous challenges in the middle of a pandemic. Previous study has not often explored the interaction between the three stakeholders (MSMEs, Regional Governments, and the Banking Sector) in economic recovery in the age of the Covid-19 epidemic. Whereas the support offered to MSMEs might stimulate economic activity in a region.

The purpose of the study was to find out that the Family Hope Program was carried out according to its purpose, namely eradicating poverty during a pandemic. The problem is focused on the implementation of the Family Hope Program (PKH) during the pandemic which has an impact on increasing poverty rates. To approach the problem. The research uses the theory of Merilee S. Grindle to build a network that allows public policy goals to be realized as a result of government activities. The research was carried out qualitatively with a descriptive approach to solving problems. The results showed that the Family Hope Program during the pandemic increased, but did not reach all affected families due to data synchronization problems. This finding indicates that the implementation of the Family Hope Program run by the Batu City Social Service is not going well.
Artificial neural network for the single-particle localization problem in quasiperiodic one-dimensional lattices
Authors: Dominguez Castro Gustavo Alexis , Paredes Gutiérrez Rosario
Published: March 2023

The use of machine learning algorithms to address classification problems in several scientific branches has increased over the past years. In particular, the supervised learning technique with artificial neural networks has been successfully employed in classifying phases of matter. In this article, we use a fully connected feed-forward neural network to classify extended and localized single-particle states that arise from quasiperiodic one-dimensional lattices. We demonstrate that our neural network achieves to correctly uncover the nature of the single-particle states even when the wave functions come from a more complex Hamiltonian than the one used to train the network.
Hadronic contribution to the running QED coupling at the Z-boson mass scale
Authors: Dominguez Cesareo , Hernandez Rosas Luis Alberto
Published: March 2023

An update is described of a model independent method to determine the hadronic contribution to the QED running coupling at the Zboson mass scale, ∆αHAD(M2 Z ). The major source of uncertainty is from the contribution of the light quark vector current correlator at zero momentum. This uncertainty is substantially reduced using recently improved lattice QCD results for this correlator. The result is ∆αHAD(M2 Z ) = 274.13(0.73) × 10−4

Published: March 2023

In this contribution, we propose a new plasmonic configuration that can be functionalized in two wavelength regimes to generate a single interface mode or multiple interface modes. The structure comprises a negative metamaterial or Left-Handed Material (LHM) coated on 2S2G-glass prism and adjacent with a sensing medium. According to the results, the negative metamaterial thickness affects significantly the potential of the structure to operate as conventional plasmonic structured formed by Fabry-Perot cavities. Additionally, we, also show that the structure can be used as a plasmonic refractive index sensor defined in the range of 1 to 1.53 refractive index unit (RIU) where the full width at half maximum (FWHM) of the SPR curve on the characteristic’s manipulation such that FWHM of p-reflectivity decreases for thick LHM layer. To understand the obtained results, the optical response from the proposed waveguide was numerically predicted by the use of the transfer matrix method (TMM) and Fresnel’s theory. In addition, the potentials of the designed waveguide as an optical modulator and Fabry-Perot interferometer are also presented.

Cerium polymeric composites have novel applications in fuel cells, optical devices, gas sensors, catalysis, ultraviolet absorbers, hydrogen storage materials, and biomedicines. This study reports the fabrication of low-cost electrospun single and core-shell polyethylene oxide (PEO) doped with Cerium fibers fabricated in two moisture ambients. Scanning electron microscopy and atomic force microscopy revealed that obtaining the thinnest average fiber diameter requires 47-52 %RH and 2 % Cerium dopant. Using a PEO capping (shell fiber) allows the increment of Cerium in the inner matrix (core-fiber) to produce non-beading continuous fibers with 3.5% of the dopant. The undoped single or core-shell fibers presented a 52.7 to 54.2 % crystallinity, indecently of relative humidity used during the fabrication process. In contrast, the use of Cerium dopant up to 2% induces an increase in their crystallinity due to the formation of Ce-O species, enhancing their thermal properties, regardless of the moisture during manufacturing as was found with Fourier transform infrared spectroscopy, differential scanning calorimetry, and thermogravimetric analysis.

Motivating by examining the break-up effect of 7Li projectile into t + α cluster structure in the field of 58Ni nucleus, the available experimental angular distributions for 7Li + 58Ni elastic scattering system at energies ranging from 13 and up to 42 MeV are studied utilizing different phenomenological as well as microscopic potentials. Data analysis utilizing the Sao Paulo potential revealed that in order to reproduce the data, the strength of the real folded potential had to be reduced by ~ 36 %. While, data analysis utilizing the double folding CDM3Y6 potential with and without the rearrangement term revealed that the potential strength needed to be reduced by ~ 63 and 62 %, respectively. Cluster folding model based on the t + α cluster structure for 7Li is applied to reproduce the considered data. Similar results were obtained showing the necessity to reduce real cluster folding potential strength by about 49 %. The reported reduction in potential strength from the different implemented potentials supports the strong 7Li break-up impact. Finally, the full microscopic continuum discretized coupled channels approach is applied with a great success in reproducing the considered data.
