Iron Overload in Patients Receiving Allogeneic Hematopoietic Stem Cell Transplantation
Authors: Busca Alessandro , Dellacasa Chiara , Pecoraro Clara
Published: March 2023

Iron overload has been associated to a variety of post-transplant complications, including infections, sinusoidal obstructive syndrome and it is conceivable that increased hepatic iron may mimic the clinical picture of GVHD or even may contribute to the worsening of hepatic GVHD.
Objectives and Methods: aim of present review was to summarize the current knowledge about diagnosis and treatment strategies of iron overload following HSCT.
Results: serum ferritin may be considered as surrogate marker of iron overload and is widely used as an indicator of body iron status; however other noninvasive diagnostic methods, namely SQUID and MRI, may provide more precise information on iron burden in specific organs, such as liver and heart. Since there are not physiological tools to remove efficiently the excess of iron, it is of particular importance to consider iron depleting therapy. Phlebotomy should be considered as the first line treatment of iron overload, while iron chelators, such as deferasirox, may represent an alternative option for patients with an inadequate hematological recovery.
Discussion: additional prospective studies are mandatory to investigate the relationship between iron overload and the outcome of patients receiving an allogeneic stem cell transplantation.

Published: March 2023

Abstract: Separation of phenolic compounds mixture namely: phenol, resorcinol, Bisphenol A from dilute aqueous solutions by polymer inclusion membrane using Cellulose triacetate (CTA) as support was investigated as a means of recovering Bisphenol A from mixture of phenolic compounds. The effects of parameters influencing the separation performance were studied in terms of permeation flux and selectivity. For competitive transport of phenols across PIM with RC8 + NPOE, the selectivity order was Bisphenol > Phenol > Resorcinol. The high permselectivity of the membrane to Bisphenol A was primarily due to its high affinity towards calixresorcinarene macrocycle. This is of particular interest from an industrial point of view because the enriched phenol permeate can be easily recovered upon phase separation. The prepared PIM were characterized by using Raman spectroscopy, XPS and scanning electron microscopy (SEM) techniques.

Keywords: PIM, CTA, Membrane separation, Phenols mixture, Bisphenol A, Wastewater treatment.

OBJECTIVES

This study aimed to provide real-world evidence on coronavirus disease 2019 vaccine effectiveness (VE) against symptomatic infection and severe outcomes caused by Omicron in children aged 5 to 11 years.

METHODS

We used the test-negative study design and linked provincial databases to estimate BNT162b2 vaccine effectiveness against symptomatic infection and severe outcomes caused by Omicron in children aged 5 to 11 years between January 2 and August 27, 2022 in Ontario. We used multivariable logistic regression to estimate VE by time since the latest dose, compared with unvaccinated children, and we evaluated VE by dosing interval.

RESULTS

We included 6284 test-positive cases and 8389 test-negative controls. VE against symptomatic infection declined from 24% (95% confidence interval [CI], 8% to 36%) 14 to 29 days after a first dose and 66% (95% CI, 60% to 71%) 7 to 29 days after 2 doses. VE was higher for children with dosing intervals of ≥56 days (57% [95% CI, 51% to 62%]) than 15 to 27 days (12% [95% CI, −11% to 30%]) and 28 to 41 days (38% [95% CI, 28% to 47%]), but appeared to wane over time for all dosing interval groups. VE against severe outcomes was 94% (95% CI, 57% to 99%) 7 to 29 days after 2 doses and declined to 57% (95%CI, −20% to 85%) after ≥120 days.

CONCLUSIONS

In children aged 5 to 11 years, 2 doses of BNT162b2 provide moderate protection against symptomatic Omicron infection within 4 months of vaccination and good protection against severe outcomes. Protection wanes more rapidly for infection than severe outcomes. Overall, longer dosing intervals confer higher protection against symptomatic infection, however protection decreases and becomes similar to shorter dosing interval starting 90 days after vaccination.

These pots are not unknown to the scientific community, they have been dealt with in various aspects in the past. However, the full details have not yet been published. The aim of this short study is to publish these vessels precisely, based on a review of the original documents and using modern digital methods. It also examines and contextualizes these important findings in the light of recent data and research.
Az avar centrum és a bizánci periféria •

Absztrakt

A késő avar ornamentika összképe erős antik hatás alatt alakult ki. A tanulmány a késő avar kori díszítőművészetben megjelenő, antik típusú, valószínűleg bizánci eredetű alakokat és jeleneteket veszi sorra. Közülük más-más típusúakkal találkozunk a késő avar kor elején, valamint közepén és második felében, és úgy tűnik, hogy e két csoport esetében az avar környezet adaptációs mechanizmusai is különbözőek. A korábbi csoport erősebb avar adaptációs hatásnak kitett motívumaival szemben a későbbi csoportra kifejtett hatás minimálisnak tűnik, és nem világos, hogy a mediterrán kultúra irányából furcsának tűnő néhány egyedi jelleg hol került a jobbára övdíszeken ismert ikonográfiába. A két csoport közötti különbség hátterében valószínűleg azon kihívások változása áll, amelyekre az avar társadalom kulturális eszközökkel kísérelt meg választ adni.

The overall picture of the Late Avar decorative art was formed under a strong antique influence. The paper discusses antique-type figures and scenes that appear in Late Avar decorative art, probably of Byzantine origin. At the beginning and in the middle–second half of the Late Avar period, there are two different groups of figures and scenes while the adaptive mechanisms of the Avar culture were also different in their case. In contrast to the motifs of the earlier group, which were subject to a stronger Avar influence, the Avar adaptation in the later group seems to be minimal, and it is not clear where some of the features that seem unusual from the context of Mediterranean culture have been incorporated into the iconography, which is mainly known from belt decorations. The differences between the early and late groups are probably due to changes in the challenges to which the Avar society attempted to respond through cultural means.
Timber-concrete hybrid structural systems: Examples, long and short-term dynamic monitoring, and numerical analysis
Authors:   ,   Linnaeus University, Faculty of Technology, Department of Building Technology, Larsson Carl
Published: March 2023

Timber-concrete hybrid buildings are an innovative solution to increase the amount of timber materials in modern buildings. Due to its lower impact on the environment than materials like steel and concrete, the demand for timber products is rising as the construction industry aims to decrease its environmental footprint.Timber is naturally grown, and certain characteristics must be considered when used in buildings, such as strength and stiffness properties depending on variables like fiber direction and moisture content. In addition, timber is a lightweight material, which influences dynamic performance of timber elements and structures.To fulfill the requirements of a modern building, timber elements are sometimes combined with concrete elements, introducing timber-concrete hybrid buildings.This study aims to expand the use of timber-concrete hybrid buildings within the construction industry. The objective is to present different types of timber-concretehybrid buildings and evaluate their structural performance to improve the level of knowledge for structural designers for the safe and robust design of such buildings.Typically, four different types of timber-concrete hybrid structures are found in building projects in Sweden. These types of building projects usually involve additional designers than regular projects due to a lack of knowledge in timberdesign. Additionally, different designers uses different statical models for their designs, even within the same building project.A mobile measurement system was developed to perform in-situ dynamic measurements. The system was used in a nine-story timber-concrete hybrid building during construction to investigate the dynamic properties and validate structural design models. A parameter study highlights different design parameters that have a large influence on these models. These parameters include the in plane shear stiffness of CLT wall elements, the foundation properties, as well asnon-load-bearing internal walls.In addition, the long-term dynamic response of a four-story office timber concrete hybrid building is presented. Over a three-years evaluation period, the results show a clear seasonal variation of the natural frequencies which correlates well with the moisture content within a CLT slab element. The results show that environmental effects are to be considered when comparing with finite element models. A predictive model is presented that can be implemented in a structural health monitoring system for damage detection so that these environmental effects can be filtered out.

The article considers the advantages and disadvantages of implementing distance learning for medical students’ training in quarantine. The issues of using e-learning methods in distance learning have been analysed. In the teaching methodology, the questions of determining the feasibility, advantages and disadvantages of implementing distance learning in the educational space and distinguishing between the concepts of “distance learning” and “e-learning” appear. The term “e-learning” is often interpreted as synonymous with “distance learning”, but the authors of this article note that this is not entirely correct. E-learning is only one of the forms used in combination with other forms of learning. Distance learning at the modern level involves the implementation of the educational process only by the network. Distance learning is a method of attending class even if students cannot be there physically. According to the Regulation “On distance learning” in Poltava State Medical University, “distance learning is a set of educational services provided through modern psychological, pedagogical, information and communication technologies”. The purpose of distance learning at the university is to introduce modern information and communication technologies to train the specialists at the educational and qualification levels “bachelor” and “master”, training programmes for interns, and advanced training of doctors according to national educational standards. The article analyses the modern pedagogical research of Ukrainian and foreign schools and presents the results of the analysis of students’ and teachers’ opinions on the introduction of distance learning in the educational process. The article also presents the results of implementing distance education at the Poltava State Medical University in the disciplines “Medical Physics” and “Medical Informatics”. The result of the study proved that distance learning has only advantages theoretically. In practice, many problems need to be solved.

The article emphasizes that every year in England the moral development of the individual receives more and more attention, and the number of programs of moral education in colleges and universities is constantly growing. It is proved that the content of tutor training programs is aimed at teaching morals, instilling values, as well as the use of various pedagogical approaches and methods. Tutoring professional development programs promote their ethical and moral development, teach them to think critically about various issues of moral and ethical content. It has been established that proper education of students by tutors helps to enrich their knowledge, morals, values and ethics. The tutor develops morals and values through many methods, such as conversation, essay writing, role play, debate, discussion, projects, interviews, brainstorming; use of resource materials through poems, stories, songs, photographs, posters and slogans. These techniques effectively help tutors teach students to critically evaluate important issues, taking into account morals, values and ethics. The article describes the forms and methods used by tutors, especially affect the development of values, morals and ethics, help to motivate students and promote universal values. Through discussion and reading, research and writing gradually, week after week, semester after semester, year after year, English students learn to think independently and, most importantly, to act according to the laws of morality. The article states that tutors have their own “style” of upbringing, which is partly related to their own experience, attitude to life, as well as individual qualities. It has been proven that students in the tutorial are in an environment that promotes their comprehensive, harmonious development and helps them succeed. Tutor support leads to the fact that the tutees are confident in their ability to make successful progress, set priorities, overcome conflicts, set realistic personal goals; ask for help, solve problems, develop their moral culture. Respect and love for the tutees show the level of development of the tutor’s moral consciousness. This love is manifested in trust, respect, exactingness, justice, nobility and kindness. It is substantiated that in order to form one’s own image and establish a trusting relationship with the tutees, a tutor carefully prepares for the tutorials; demonstrates his or her respect, sincerity, empathy, interest and contact; is friendly, always in a good mood; penetrates into the spiritual world of the tutee, takes into account his or her values and preferences; offers and asks for help, listens to advice; determines what impresses and fascinates them.

The article focuses on theoretical foundations of the formation of primary school students’ research skills in the educational process of the New Ukrainian School; it presents the peculiarities of psychological and pedagogical support for students’ research in primary education. Research skills are defined as the ability of a primary school student to observe, compare, analyse, research, synthesise the acquired knowledge with the formed readiness to perform new tasks productively. It is proved that the components of research skills include teaching methods and techniques based on cooperation, principles of continuous developmental interaction between teachers and students, formation of their research framework, behaviour, practical research skills, actualizing intellectual sphere, curiosity, insight and rational thought. The author proves that the realities of today require radical thinking, in the context of research alternatives, and updating certain aspects of the educational process in general secondary education, emphasizing the actualization of personally transformative meaning of research in primary school students. It requires, in its turn, cognitive cooperation, which will provide stimulating, generative learning, an accelerated transition to new, modified structures of knowledge and research behaviour. At the ascertaining stage of the pedagogical experiment the target orientations concerning the process and state of formation of primary school students’ research skills in the educational process of the New Ukrainian school are investigated. They are as follows: determination of their cognitive needs, desires for independent creative research activity; desire to work in a group of young researchers, experiment; knowledge of how to work with information on planning research; hypotheses; research presentations; diagnostics of difficulties in mastering theoretical knowledge, practical skills and competencies in research. The results of the analysis of the primary school students’ research skills formation in the educational process of the New Ukrainian School, the results of the ascertaining stage of the pedagogical experiment showed insufficient and even low level of the formation of the studied phenomenon.

The article provides a practical overview of the use of STEM-learning technology, which aims to establish interdisciplinary links that contribute to the formation of students’ holistic, systematic worldview, modern personal attitudes to the issues. Such lessons or classes can be conducted by combining the subjects of several subjects or the formation of integrated courses or separate special courses for students during distance education. In the conditions of distance education, the use of dynamic web-services in the professional activity of a teacher acquires practical significance, with the help of which it becomes possible to work with students some curriculum materials with the involvement of STEM-technologies. Own experience and experience of teachers of the Zaporizhzha region in the implementation of the study of real natural processes that can be carried out in distance learning, was analyzed. In this way, teachers found out and used several interesting dynamic web-resources that are fully or partially publicly available and do not require additional financial costs (registration or subscription) when conducting lessons on the basis of STEM. Thus, the available teaching aids can be used in classroom (face-toface) work, when the teacher uses a projector to demonstrate to the whole class activities on the resource, or in individual or group work, using smartphones as teaching aids. The experience of practical use of sites was carried out in KZ “ZOIPPO” ZOR in teaching the discipline of information and communication technologies, where teachers read web pages and train to compose tasks for students to use them in their daily teaching practice. Due to such tasks, in the study of the world economy and the national economy, students develop an awareness of global interdependence and personal responsibility. Such activities immediately implement several cross-cutting levels of the curriculum: a holistic scientific view of the world, an adequate understanding of the peculiarities of the modern world; understanding of the unity and harmony between the natural environment, the development of material production and the level of growth of social standards of the population in conditions of sustainable development. Of course, involvement in distance learning format is not able to fully replace the face-to-face format. But to reinforce theoretical material, it can be a good alternative for understanding natural phenomena or processes in the study of physics, astronomy, geography, geology, biology and ecology, chemistry, etc.

According to recent studies, about 19% of the population in Peru is at risk of suffering from respiratory diseases due to frost, which is a drop in temperature below 0°C and causes a decrease in thermal comfort inside homes. In addition to these respiratory diseases, frost also increases the risk of other cold-related health conditions, such as hypothermia and circulatory diseases. Therefore, it is important to implement measures to improve thermal conditioning and reduce the risks of these diseases in the affected population. For this reason, the purpose is to improve thermal conditioning through the use of natural insulation. An investigation was carried out in the district of Taraco, using a rural house as a sample. The internal and external temperatures of the house were measured every half hour for 24 hours, and plans of the house were drawn up to collect information. It is proposed to make a natural thermal insulator with quinoa, to increase the temperature by 2 °C inside the house during the night. The thermal conductivity of the material will be evaluated. This study seeks to promote the use of local materials and thermal comfort to achieve sustainable development in the affected population and can be replicated in other areas of the country.

Published: March 2023

Complications of chronic kidney disease (CKD) impair cardiovascular health and quality of life. Health-related QoL (HRQoL) is influenced by cultural perspectives, social environment and health behaviors that vary across countries with varying income. Therefore, present review aims to report HRQoL in people with CKD and factors influencing HRQoL in low- and middle-income countries (LMICs). Fifty relevant studies were reviewed following literature search in Cochrane Library, PubMed, Google Scholar and CINAHL databases using key words: quality of life, CKD, and LMICs. HRQoL was poor in people with CKD compared with healthy individuals. QoL was positively influenced by younger age, male gender, employment and higher socioeconomic status. Presence of comorbidities, anemia and low hemoglobin levels were associated with poor QoL. Intrinsic and extrinsic factors influencing HRQoL were similar in people with CKD in LMICs and high-income countries (HICs). However, overall HRQoL and mental-health scores were lower with reference to HICs. Therefore, a multipronged approach designed towards prevention of kidney disease, early detection and management to delay end-stage kidney disease through health education, modification of risk factors, accessible and affordable comprehensive management of kidney disease is necessary. In resource constrained settings of LMIC, strategic investment in planning and implementation of prophylactic and monitoring measures will help to reduce huge financial costs necessary for management and improvement of HRQoL of people with CKD.

Published: March 2023

INTRODUÇÃO: A dessaturação da oxihemoglobina induzida pelo exercício em pacientes pós-COVID-19 parece estar associada à redução da difusão e dos volumes pulmonares, à maior dispneia e baixa capacidade funcional, sendo relacionada à maior mortalidade e pior prognóstico. A reabilitação cardiopulmonar e metabólica (RCPM) é relevante, pois visa restaurar a funcionalidade, tolerância ao esforço e a qualidade de vida (QV). OBJETIVO: Verificar os efeitos da RCPM em pacientes que apresentaram dessaturação da oxihemoglobina induzida pelo exercício após alta hospitalar pela COVID-19 e ainda observar a diferença entre os treinamentos contínuo de moderada intensidade (TCMI) e o intervalado de alta intensidade (TIAI) na tolerância ao esforço, nos sintomas e na QV. MÉTODOS: Trata-se do relato de uma série de 4 casos que foram hospitalizados por COVID-19 e que após alta hospitalar apresentaram dessaturação da oxihemoglobina induzida pelo esforço durante o teste do degrau de 6 minutos (TD6). Os pacientes foram avaliados por meio de espirometria de repouso, mensuração da força da musculatura inspiratória, TD6, teste da caminhada de 6 minutos (TC6), teste de repetições máximas do quadríceps e bíceps braquial e responderam ao questionário SF-36 de QV. Submetidos a um protocolo de treinamento contendo treino da musculatura inspiratória e treino resistido para grandes grupos musculares, adicionalmente, 2 pacientes fizeram TCMI (com 60-80% da frequência cárdica de reserva (FCR)) e 2 TIAI (com 40% da FCR na fase off, durante 4 minutos e 80 a 100%, na fase on, durante 2 minutos) em esteira por 30 minutos e, por fim, após 3 meses foram reavaliados. RESULTADOS: Observou-se aumento da tolerância ao esforço, da força muscular inspiratória e periférica, além da melhora da QV e redução dos sintomas em todos os pacientes após a RCPM, porém houve incrementos maiores nos pacientes submetidos ao TIAI comparados ao TCMI na distância percorrida em metros (caso 1- 156 (23% de incremento); caso 3 - 168 (40%)) versus (caso 2 e 4 - 60 metros, com incrementos de 9% e 14%, respectivamente) e maior número de degraus (caso 1- 28 (23% de aumento); caso 3- 37 (34%)) versus (caso 2 – 2 (2% incremento); caso 4 - 15 (21%)). CONCLUSÃO: A RCPM apresentou efeitos positivos, com incremento da capacidade funcional e melhora da QV, além da redução dos sintomas durante o esforço, particularmente nos pacientes submetidos ao TIAI.

Published: March 2023

Eggshell Membrane (ESM) has been used as an alternative natural bandage to cure wounds and is available in large quantities from egg industries. This study is based on the use of natural resources for skin tissue reconstruction. It needs to understand regeneration of tissue with Extracellular Matrix (ECM). Wound healing is a complicated and continuous recovery process of damaged tissues by replacing dysfunctional injured cellular structures. The wound healing process recruits some different phases: the first phase for hemostasis, the second phase for inflammation, the third phase for proliferation, and last phases for maturation/tissue remodeling. Each process needs an appropriate surrounding to achieve accelerated healing. Because the skin is in contact with the outside, injuries occur and therefore the surface is often injured. Due to the different types of wounds, as well as the advancement in medical technology, various products have been developed to repair different skin lesions. We investigate the wound healing effects which are measured by dividing into the Exture® group, the commercially available wound dressing group (positive control), and the untreated group (negative control). We induced wounds and measured the healing process for 20 days for a comparison experiment of collagen membrane wound healing. As for the wound, the decrease in wound area using external photographs, the healing process within the tissue, and the immune response were measured through hematology analysis. We confirmed some differences through comparison of blood cell analysis and wound healing process but did not find statistical significance. There was no significant difference between treated collagen wound dressing film and commercial wound dressing film. Thus, this study reveals that the possibility of use natural source-based wound healing products brings sufficient wound healing results.
Multiplexed Iterative FISH Experimental Protocol SOP002.v3.12 v2
Authors: Kruithoff Rory
Published: March 2023

This document, SOP002 - Multiplexed Iterative FISH Experimental Protocol, describes the process for in-situ fluorescence labeling of RNA transcripts in cells and tissues using a layered probe design, which allows for identity barcoding (MERFISH or similar). This protocol also provides the option for signal amplification using Branched DNA [bDNA] amplification. Iterative rounds of labeling and imaging are possible through the use of a readout probe with a cleavable disulfide (S-S) reporter molecule, a method that allows for minimal disruption to sample integrity between rounds.

This paper presents a review of sensors and inspection devices employed to inspect railway defects and track geometry irregularities. Inspection of rail defects is an important task in railway infrastructure management systems, and data derived from inspections can feed railway degradation prediction models. These models are utilised for predicting potential defects and implementing preventive maintenance activities. In this paper, different sensors for detecting rail defects and track irregularities are presented, and various inspection devices which utilise these sensors are investigated. In addition, the classification of the sensors and inspection devices based on their capabilities and specifications is carried out, which has not been fully addressed in previous studies. Non-Destructive Testing (NDT) sensors, cameras and accelerometers are among sensors investigated here. Correspondingly, trolleys, Condition Monitoring Systems (CMS), hi-rail vehicles and Track Recording Vehicles (TRV) are among major inspection devices that their capabilities are studied. Furthermore, the application of new devices, including smartphones and drones, in railway inspection and their potential capabilities are discussed. The review of previous and recent approaches shows that CMSs are more cost-effective and accessible than other railway inspection methods, as they can be carried out on in-service vehicles an unlimited number of times without disruption to normal train traffic. In addition, recently smartphones as a compact inspection device with a variety of sensors are employed to measure acceleration data, which can be considered as an indicator of rail track condition.

In recent years, increasing interest in 3D Printing (3DP) has meant that printer usage is not limited to industrial purposes only, but is also for domestic usage by hobbyists for their individual needs. Polymer-based part production can now even be conducted outside the traditional factory environment. However, low grade printers pose some drawbacks, such as lower heat for material fusion, uncontrolled open ambience and limited nozzle size. These reduce the mechanical and aesthetical qualities as compared to parts fabricated using industrial grade printers. The study aims to perform some quality comparisons between 3D printed polymeric parts fabricated by both industrial and low cost printers, and subsequently to prove the hypothesis that the industrial grade printed part has a more reliable surface quality and mechanical properties. Specimens were fabricated using each printer type (Fused Deposition Modelling (FDM) represents the low cost printer and the Multi Jet Printer (MJP) is used for the industrial grade) and later tested for hardness and surface roughness. Comparisons were then made between different fabricating methods and also based on a literature study according to the type of materials. The experiments showed that both the surface roughness and hardness for the plastic parts fabricated by the industrial grade printer were better than those made by the domestic printer, and showed a good agreement with the results in the literature study. Therefore, for highly durable parts, it is suggested that industrial grade printers are used. One point to conclude the study, Rapid Prototyping is possible by any machine, but for Rapid Manufacturing that requires higher durability, it is better to use an industrial grade printer.

Fishermen, particularly those in coastal seas, are often categorized under low-income community. Many efforts have been taken to assist this community to sustain their livelihoods, but hampered by various factors such as high operational cost. Coastal fishing boats specifically made from fiberglass are greatly dependent on petrol-powered outboard motor to generate power. The high fuel consumption of outboard motors is believed one of the factors that contribute to their high operational cost. To this end, it is necessary to dive into the fishermen’s perception on this issue. This paper presents finding on the perception of coastal fishermen towards the performance of outboard motors and their views on fuel-saving engines. Some key areas are discussed and explained in this paper. A questionnaire had been developed as a survey tool; divided into three parts, covering cost factor, engine factor and operation factor. The questionnaire was developed based on Likert scale and distributed to randomly selected respondents among the fishermen community at Manjung, Perak. The data was then processed using Statistical Package for Social Science (SPSS). The results showed that inshore fishermen are not satisfied with petrol outboard motor, with more than 95% confidence level.

Solar energy is the most abundant nature resources on earth which easily exploitable, clean, long lasting and dependable which make it is desirable to generate electricity compared to other energy resources. However, conventional solar photovoltaic (PV) technologies such as silicon and thin film solar cells may provide significant environmental impacts over their life cycle due to complicated production process of these PV technologies. This make numerous scientists looking forward on the new emerging solar cells including dye sensitized solar cell (DSSC). Thus, the objective of this research is to analyse a comprehensive environmental impact assessment through life cycle assessment (LCA) from cradle-to-gate approach of this technology in Malaysia. Two environmental indicators were evaluated such as cumulative energy demand (CED) that affect the energy payback time (EPBT), and greenhouse gas (GHG) emissions. The results highlight that DSSC module has EPBT of 3.49 years, CED of 1190.29 MJ/m2 and GHG emissions of 262.38 gCO2eq/kWh which were slightly higher compared to other researchers. Higher energy consumption in module fabrication and panel manufacturing process, lower conversion efficiency (ŋ) and solar irradiation (IR), and used of FTO glass substrate were recognized as main contributors to the results.

The importance of a Bachelor Program in Engineering Physics for underdeveloped and developing countries is discussed in this paper. Worldwide rapid developments need reliable engineering graduates with strong inter- and multidisciplinary academic qualifications. Anticipating this requirement, Bachelor degree program in engineering physics is regarded as the most suitable for preparing graduates in underdeveloped and developing countries with such qualification profile. Several studies showed that the need for such educational program is quite promising. The motivation to strive for higher qualifications is strong, and it is motivated by individual as well as the institutional consciousness, as also triggered by labor market requirements and government’s incentives. It is not surprising that the similar qualification profiles are already well designed in many industrial countries for Master up to PhD levels. Since the program requires a cross-discipline study among many fields, this paper also discusses the synergistic clustering strategy for facilitating the learning, research, and developmental activities. In this paper, seven clusters are proposed, namely generic knowledge, basic knowledge, instrumentation and control, energy and environmental engineering, materials, acoustics and vibration, and photonics. The cluster courses can be distributed in each semester depends on the department strategy of achieving the learning outcomes. Mandatory courses for such program are also being addressed as well.
