Published: September 2021

Masalah gizi masih menjadi masalah di dunia terutama di negara berkembang. Stunting adalah keterlambatan pertumbuhan yang merugikan sehingga menjadi prioritas dalam program kesehatan. 30,8 % balita di Indonesia mengalami stunting dan menjadi penyebab morbiditas dan mortalitas. Tujuan dari penelitian ini adalah untuk mengetahui apakah ada hubungan antara  pemberian ASI eksklusif dengan kejadian stunting dengan mempertimbangkan variabel luar yaitu status ekonomi, pendidikan ibu, tinggi ibu, umur ibu saat hamil, panjang lahir, dan berat lahir pada anak dibawah lima tahun di Daerah Istimewa Yogyakarta. Penelitian observasional menggunakan rancangan kasus kontrol (case control). Penelitian dilaksanakan di dua kabupaten di DIY yaitu di Kabupaten Gunung Kidul dan Kota Yogyakarta. Sampel penelitian sebanyak 110 balita. Hasil penelitian (analisis bivariat) menunjukkan bahwa tidak ada korelasi yang signifikan antara pemberian ASI eksklusif, status ekonomi, pendidikan, tinggi badan ibu, umur ibu hamil, dan berat lahir dengan stunting. Panjang lahir berkorelasi signifikan terhadap stunting pada balita (Pv=0,002; OR=3,75; CI=1,57-9,97). Analisis regresi logistik menunjukkan bahwa tidak ada korelasi yang signifikan antara ASI eksklusif dengan kejadian stunting setelah mempertimbangkan variabel lain yaitu status ekonomi, pendidikan, panjang lahir, dan berat lahir.

Uterine fibroids, also known as leiomyomas, are the most common uterine neoplasms. Although benig, they can be associated with a significant number of morbidity and are the most common indication for hysterectomy. Transvaginal ultrasonography (TVS) has become essential in the diagnosis and management of the uterine fibroids. TVS provides a detailed examination of uterus and ovaries. However, there is no nation-wide and regional clinical study on the use of TVS for the evaluation of uterine fibroids in Bangladesh. In this work, a cross-sectional study toob serve the role of TVS in the evaluation of uterine fibroids in a region of Bangladesh (Greater Mymensingh). In the diagnosis of uterine fibroids by TVS, we observed that 35(81.4%) cases (out of 43) are fibroids and 8 (18.6%) cases are non-fibroids. In histopathological diagnosis, we found 36 (83.7%) cases are uterine fibroids, and 7 (16.3%) cases are without fibroids. In this study, TVS diagnosed uterine fibroids with a sensitivity of 94.4%, the specificity of 85.71%, the accuracy of 97.6%, the positive predictive value of 97.1% and negative predictive value of 75%. The results demonstrate that TVS has the potential to become a useful imaging tool for the evaluation of uterine fibroids.

Published: September 2021

Introduction: Infertility as a global health issue is very much attended by the health sectors of most of the developed countries of the world. It remains as a neglected issue in Bangladesh’s reproductive health policy as emphasis is always been on the problem of overpopulation. Bangladesh Armed Forces have come forward to establish the first government set-up Artificial Reproductive Technology (ART) center to help the infertile couples of Bangladesh.
Aim: To assess the outcome of in-vitro fertilization (IVF) procedures in relation to different demographic characteristics of the patients getting treatment at Fertility center, combined military hospital (CMH), Dhaka.
Methods: Out of more than thousand patients, 46 couples were selected for IVF cycle scheduled to be held on the month of July 2017 and October 2017. Each selected female and male patient had a normal basic fertility work up. In both batches, female factors were predominant. Male factor and combined factors were also present. Data were collected prospectively using a data collection sheet over the period of one year starting from July 2017 to June 2018 to observe the last patient upto the delivery of her offspring.
Results: A total of 46 couples or 92 patients were treated for infertility. Out of 46 female patients, most (about 40%) were within the range of 26 to 30 years of age. About two-thirds patients had primary subfertility. Most common cause of infertility of female partners was the tubal cause (52%) and of male partners was severe oligozoospermia (47%). A procedure of IVF like conventional IVF was done in 64% and Intra Cytoplasmic Sperm Injection (ICSI) in the remaining. Embryo transfer was performed in 30 patients. The embryos of 13 (33%) patients were cryopreserved in both batches. Rate of retrieved oocytes ranged from 3 to 29 in the 1st batch and for the 2nd batch it was from 1 to 17. Pregnancy rate was 80% in first batch, but in the second batch it was only 33%. Abortion rate was also very high (80%) in the second batch.
Conclusion: In fact, infertility has become a burning health issue to the sufferers of fertility problems as well as career-oriented generation of this century and the society seeks the remedy to help them. Like the Fertility Center, CMH, Dhaka other government set up centers should come up to provide facilities that enables the women having the dream of motherhood true.

Published: September 2021

Introduction: Cholelithiasis is being frequently diagnosed in children, although not as often as in adult. The real aetiology of gallstone formation is poorly understood, but some inciting factors are assumed to be involved in gallstone formation in children. Traditionally cholelithiasis in children is classified as haemolytic or nonhaemolytic in origin. Nonhaemolytic cholelithiasis seems to be more frequent than haemolytic cholelithiasis at present.
Aim: To find out the pattern of childhood cholelithiasis presenting in a tertiary level military hospital.
Methods: This retrospective observational study was carried out in the Department of Paediatric Surgery, CMH Dhaka from January 2015 to December 2018. A total of 35 children with cholelithiasis were admitted in this hospital.
Results: During the study period 35 children with cholelithiasis were admitted. Among them maximum children 31(88.6%) were in the age group of 6-12 years. Out of them 23(65.7%) were female and 12(34.3%) were male making a female to male ratio of 1.92:1. Twelve children (34.3%) were asymptomatic and 23(65.71%) were symptomatic. Among symptomatic group 10(28.6%) had biliary colic, 10(28.6%) had nonspecific abdominal pain and 3(13.0%) had acute abdominal pain. Out of these 35 children, only 4(11.4%) had link with haemolytic anaemia.
Conclusion: Cholelithiasis in children is being recognized with increased frequency in recent years. The ratio of cholecystitis and cholelithiasis varies considerably in different countries and centres. Childhood cholelithiasis has less chance of complication and high rate of resolution.

Published: September 2021

Conventional plastic becomes trend topic due to its long degradation time and needs attention related to environmental problem. One type of plastic that is difficult to be degraded is LDPE. Some of the efforts done is to synthesize plastics with organic material so that it becomes biodegradable plastic. Cellulose is an organic material that is abundant in nature and can be used as a filler. This research aims to synthesis the biodegradable plastic films composted by nanocellulose – LDPE. Mechanical (UTM), water resistance and degradation test has been done. The properties of the biodegradable blend still meet the commercial LDPE standart. Even though the biocomposite based on LDPE-nanofiber cellulose can not totally degradable but it is can be used as a solution to reduce the degradation time of a plastic waste.

Authors: Mandalagiri Levina , Irawan Anton , Yani Setyawati
Published: September 2021

Energy conservation has recently become one of the most important considerations in industries, especially in petrochemical industries. This is due to the limited availability of fuel which affects the price of energy sources, as well as the tightening of the regulations concerning environmental and social issues related to pollutant emissions produced by industries. The successful energy-saving efforts made by industries impact on not only lowering production costs but also indirectly preserving natural resources as well as reducing the pollution of CO2 which is one of the gases contributing to global warming. Pinch analysis has been widely known for process integration, especially in heat integration, in order to gain energy efficiency and cost efficiency in many industries for decade. The analysis allows selection of efficient heat exchanger network with minimum hot and cold energy requirement. By using pinch analysis, the number of heat exchanger units required could also be minimized which leads to the optimum cost of operational and investment. Pinch analysis is also allowing for the investigation of any pinch problems, such as pinch threshold problems, cross pinch problems, and problems related to incorrect placement of utilities which impacted to the wastefulness of energy consumption. Despite many success studies of highly potential saving of heat integration through pinch analysis, the real implementation of efficient and effective heat exchanger network (HEN) based on pinch analysis is still facing difficulties, for example in term of flexibility and controllability of operation.  This paper provides preliminary information in increasing energy efficiency or energy savings when utilizing pinch technology considering operability and flexibility of its operation for retrofitting units for chemical industrial plants.

Activities of Acetylcholinesterase, Oxidative and Nitrosative Stress Markers in Clarias gariepinus Exposed to ‘Uproot’, a Glyphosate–Based Herbicide
Authors: E Osioma , A.S Ejoh
Published: September 2021

In this study, Clarias gariepinus were exposed to different concentrations (60, 80 and 100 mg/L) of
Uproot, a glyphosate-based herbicide and the activities of acetylcholinesterase (AChE), hepatic enzyme markers,
oxidative and nitrosative stress markers were determined in serum, gills, liver and brain by using standard assays.
Results showed that AChE activity was not significantly inhibited. Activities of ALT, AST and ALP increased (P <
0.05) with increasing exposures. For SOD, elevated (P < 0.05) activities were observed in all tissues at 60 mg/L
exposure, but decreased at 80 mg/L and 100 mg/L concentrations. The activity of CAT reduced significantly (P <
0.05) in brain at 100 mg/L exposure. Increased production of NO was observed in gill and brain whereas in serum it
is increased. GPx was elevated in gills and reduced in brain and liver. Gills showed lower MDA concentrations. GST
was el evated in liver and brain, while total protein reduced (P < 0.05) in serum, gill and liver with increasing
concentrations of exposure. The impaired activities of antioxidant enzymes and induction of NO suggest a
disruption of normal antioxidant response in Clarias gariepinus exposed to glyphosate, and these activities could be
used as biomarkers in aquatic environmental contamination

Authors: R Chourpagar Atul , S Shaikh Rumana
Published: September 2021

In recent times aquaculture has become an increasingly important part of the world economy. Copepods
play major roles in pond ecosystems serving as food for small fish, micro-predators on fish and other organisms,
fish parasites, intermediate hosts of fish parasites and hosts and vectors of human diseases like cholera. Growth,
reproduction and biochemical composition were analyzed for the copepod Mesocyclops leuckarti fed on four diets
and their ratio like Bakers yeast (B), Baker’s yeast+ Wheat flour (BW, 1:2), Bakers yeast + Chicken manure (BC, 1:2)
and Bakers yeast + Chicken manure + Wheat flour (BCW, 1:2:2). The mean peak density of the copepod population
was 569 individual/lit, for all four diets used. The highest was 587 individual/lit, on diet having combination of
Bakers yeast, Chicken manure and Wheat flour (BCW). A small copepod Mesocyclops leuckarti tends to have a short
life span and it was found to be important food items for fish larvae.

Published: September 2021

In this study toxicity of Euphorbia royleana latex and stem bark extract was evaluated in a static bioassay
test for the fry and fingerlings of freshwater fish Channa punctatus. For fry the LC50 values for Euphorbia royleana
latex were 12.66, 6.27, 4.04 and 3.05 mg/L whereas for stem bark extract the LC50 values were 113.77, 89.16, 71.99
and 56.59 mg/L for 24, 48, 72 and 96 h, respectively. It seems that toxicity of latex was more pronounced as
compared to stem bark extract. The LC50 values for latex for fingerlings were 22.58, 18.14, 14.99 and 12.34 mg/L
whereas for stem bark extract the LC50 values were 614.35, 585.06, 535.93 and 475.37 mg/L for 24, 48, 72 and 96 h,
respectively. The activities of the latex and stem bark extract were time- and dose-dependant. The present study
clearly indicates that Euphorbia royleana extracts should be applied with great precautions nearby the aquatic
reservoirs as it is toxic to growing stages of the fish.

Published: September 2021

Gut microbiota of termites belonging to the species Coptotermes ceylonicus is known to contain plethora
of enzymes of which cellulase is the most important among them. Cellulase was successfully extracted and isolated
from the gut of these termites by using standard protocol. Cellulytic index was calculated and found to be 3.25. The
extracted crude enzyme was partially purified by Dinitro Salicyclic Acid (DNS) method. Extracted cellulase enzyme
was screened for antibacterial activity against two bacterial species, Escherichia coli (E. coli) and Bacillus subtilis (B.
subtilis) using well diffusion method. Partially purified cellulase enzyme showed effective antibacterial activity
against E. coli (16 mm of zone of inhibition), however, there was no such effect observed in the B. subtilis. In this
study we successfully isolated cellulase enzyme from the gut of Coptotermes ceylonicus and confirm its bactericidal
effect against E. coli. Further studies are required to test the bactericidal effect of cellulase against different bacterial
species.

Authors: Vargas Garcia Miguel Antonio , Cely Arboleda Angelica , Suarez Juliza Tatiana , Vélez Gutiérrez Diego Alejandro
Published: September 2021

La disfagia es conocida como la dificultad o incapacidad a la hora de la ingesta de alimentos, la cual es analizada desde diferentes puntos ya que puede ser generada por factores anatómicos, sean estos de nacimiento o adquiridos, causas psicológicas o funcionales. El quehacer profesional en disfagia permite clasificar la severidad de la disfagia, pero no la calificación del riesgo de los distintos errores funcionales durante la ingesta. A razón de ello, este escrito propone clasificar el nivel de riesgo por errores funcionales de la deglución.

La investigación se planteó desde una naturaleza prospectiva con relación de validez, a través del método Delphi, mediante la cual se postuló una lista de errores funcionales de la deglución para ser validada por 6 jueces expertos en el área. Se realizó una propuesta en una matriz, que les permitió evaluar los distintos errores funcionales divididos en las fases deglutorias y los niveles de riesgo para repercutir en disfagia, según los ítems de suficiencia, relevancia, coherencia y claridad. Se obtuvo una lista de 38 errores validados, los cuales se fundamentan como riesgo, dado que al materializarse fomentan en la secuencia deglutoria una mayor probabilidad de penetración/aspiración de alimento hacia vía aérea. El consenso de la clasificación de estos errores según el riesgo, será una herramienta útil para profesionales del área. Se concluye, a través de la diferencia mínima significativa (LSD) de Fisher para medias, una lista de riesgos por errores funcionales de la deglución, en orden descendente según la severidad del riesgo que representa el error en la ingesta.
A Holistic Approach for Optimal Pre-Planning of Multi-Path Standardized Taxiing Routes
Authors: Yang Lei , Wang Simin , Liang Fengjie , Zhao Zheng
Published: September 2021

Standardized Taxiing Routes (STRs) are defined as published taxiing-in and taxiing-out routes for aircraft between gates and runways, aiming at improving ground movement safety at busy or complex airports. Most of the STRs specify only one path between each O–D (Origin–Destination) pair, which compromises the flexibility of route choice in time-varying traffic scenarios. In this paper, we present a holistic approach of planning and validating Multi-Path Standardized Taxiing Routes (MPSTRs) based on System-Optimal Traffic Assignment (SOTA), by firstly defining the flow-based congestion cost of runway, taxiway, and sectorized apron operation at a macroscopic level. A human-in-the-loop experiment comprised of six operation scenarios follows to investigate the impact of the pre-planned MPSTRs on human controllers’ performance. Results confirm the positive effect of the MPSTRs on taxiing performance without increasing the controllers’ workload, which also implies that the MPSTRs would be a promising approach for balancing safety and efficiency for the STRs-based taxiing operation and dynamic routing optimization without substantial investment.

Authors: Čechura Lukáš , Žáková Kroupová Zdeňka , Benešová Irena
Published: September 2021

The study aims to explore the sources of competitiveness of dairy producers before and after the abolition of milk quotas in selected EU member states. The investigation is based on the stochastic frontier modelling of an input distance function in the specification of the four-error-component model. The model is estimated with a multistep procedure employing the generalized method of moments estimator, addressing the potential endogeneity of netputs, and panel data gained from the FADN database. The results revealed that total factor productivity experienced an increasing trend in the majority of the analysed countries. Since the main driver of productivity growth was found to be the scale effect, our findings support the hypothesis that abolishing milk quotas has a positive effect.
Market Imperfections within the European Wheat Value Chain: The Case of France and the United Kingdom
Authors: Čechura Lukáš , Jaghdani Tinoush Jamali
Published: September 2021

The focus of this paper is on the analysis of market imperfections in the French and U.K. wheat value chains. We used mark-up and mark-down models and stochastic frontier analysis to estimate the degree of market imperfections in two completely different wheat-to-bread chains for two stages/sectors—milling and baking. Our results reveal some degree of market imperfections within the input and output markets for both the milling and baking sectors in France and the United Kingdom. However, the abuse of bargaining power is especially pronounced in the input market for the second stage of wheat processing, particularly in the French baking sector. However, we did not observe the expected positive association between the degree of market imperfections and company size except for a group of middle, large, and very large companies within the millers’ input market. Small companies indicate considerably high values of “Lerner”/Lerner indices, suggesting a benefit from other sources of competitive advantage (such as quality, niche markets, etc.).

Herbal infusions are consumed worldwide owing to their beneficial properties. Cultivated or obtained from the wild, herbal raw plant materials may contain trace elements at various levels. This study relates to the release of beneficial and potentially toxic trace elements from herbal preparations during infusion. The elemental contents of seven commercially available herbal tea products were determined prior to and following two modes of infusion. Teabags (of equal herb content) were infused in 200 mL of boiling bottled water “Holy Spirit” for 15 and 45 min, in glass beakers.

The objective of this study was to evaluate the performances of three cassava genotypes on yield, physiology and morphological traits under different fertilization regimes. A field experiment was conducted in a split-plot design for two consecutive seasons in the Mansa district of the Luapula Province of Northern Zambia in the highly weathered Chromi-haplic Acrisol soils. Four fertilization regimes, control-M3, lime-M1, NPK fertilizer-M4 and NPK fertilizer + lime-M2 were the main plots, while three varieties (Mweru-V1, Bangweulu-V2 and Katobamputa (local)-V3) were subplots. Periodic measurements of leaf area index, light interception, yield and yield components from 75 days after planting (DAP) up to 410 DAP and daily weather measurements of data were recorded. Fertilization significantly increased the radiation use efficiency (RUE) and light extinction coefficient (K) in two seasons compared to the control. Significant fertilization regimes and varietal effects were observed for seasonal LAI, stem yield, root yield, biomass, harvest index (HI), tuber number, root diameter, plant height and SPAD (chlorophyll index). A significant year’s effects on root yield, yield components and physiological performances were observed while significant fertilization × variety interaction was observed on seasonal LAI, tuber number, root diameter, plant height and SPAD. Significant fertilization × year interaction effects were observed on root yield, yield components and physiological performances. Variety × year interaction was significant for seasonal LAI, stem yield, harvest index and plant height and no three-way interactions were observed on all the traits. NPK fertilizer + lime and NPK fertilizer treatments may be adopted to increase the response of cassava varietal yield, physiology and morphological traits in low soil nutrient conditions under high rain-fed conditions.

Turkeys’ body weight (BW) increases 10-fold within only 2.5 months, leading to a change in the pharmacokinetics (PK) of drugs according to allometric principles. Thus, the same dosage may lead to age-dependent variability in efficacy, in particular, to treatment failure and/or selection for resistance. The study aimed to investigate whether a non-linear dosage based on a published allometric model for tylosin clearance, may optimize the internal exposure in growing turkeys. The single dose PK study was performed on turkeys aged 6, 9.5, 13 and 17 weeks (BW from 1.75 kg to 15.75 kg). Tylosin was administered intravenously (i.v.) or orally (p.o.) according to following protocols: Dose = 31.6 × BW0.58 or Dose = 158 × BW0.58, respectively. Plasma tylosin was measured using high-performance liquid chromatography and non-compartmental PK analysis was performed. The area under the curve (AUClast) after i.v. administration was 8.90 ± 1.01; 7.51 ± 1.11; 6.54 ± 1.20 and 8.01 ± 1.75 mg × h/L in 6-; 9.5-; 13- and 17-week-old turkeys, respectively. After p.o. administration AUClast was 4.80 ± 2.92; 4.60 ± 2.45; 3.00 ± 1.49 and 3.24 ± 2.00 mg × h/L in respective age groups indicating high variability. For i.v. administration, the non-linear dosage allowed to minimize the age-dependent variability in AUC. However, due to low oral bioavailability (8–12%) and resulting interindividual variability, the proposed approach may not improve tylosin efficacy in turkeys under farm conditions.

Young barley seems to be a promising material for use as nutricosmetic due to the presence of many biologically active compounds. The aim of this study was to evaluate the effect of Hordeum vulgare L. extracts on human skin fibroblasts exposed to ultraviolet radiation B (UVB) radiation. Analysis of the chemical composition showed a predominance of 9,12,15-octadecatrienoic acid. The quality assessment showed that young barley preparations have high total polyphenolic content (TPC) and favourable total antioxidant status (TAS). They also contain antioxidant elements such as zinc, copper, and selenium. Furthermore, the analyzed products were found to be safe in terms of toxic elements (lead, cadmium and mercury) and lack of cytotoxic effect of young barley extracts on cells. In vitro bioactivity assays showed that young barley extract increased the survival rate and accelerated the migration of fibroblasts in research models with UVB radiation. The application of both extracts caused an increase in DNA biosynthesis, and in the number of cells arrested in S phase. Moreover, an inhibitory effect of the tested extracts on the expression of matrix metalloproteinase 2 (MMP-2) and matrix metalloproteinase 9 (MMP-9) was observed. The results indicate that young barley extracts, due to protective as well as restorative effect, could potentially be used in the production of nutricosmetics and skin care products.

Published: September 2021

Long Range Wide Area Network (LoRaWAN) is the one of the promising low power wide area network (LPWAN) technologies at present and is expected to grow in the foreseeable future as a tool to provide connectivity among small things. In this paper, we present a simple analytical model to compute the throughput and packet loss probability of Medium Access Control (MAC) for Class-A of LoRaWAN. This analysis results can be used as a reference for deploying the appropriate number of end-devices (EDs) that can be accepted in a gateway (GW) while maximizing network throughput or guaranteeing the packet loss rate of EDs.

An electroanalytical study for possible simultaneous detection of three naturally occurring isomers of vitamin E (α, γ, and δ-tocopherol) was performed. This research includes several optimization steps, such as selection of electrode material, composition of working medium, selection of electrochemical technique, and parameters of square-wave voltammetry (SWV), to reach a well-defined recognition of peaks. A glassy carbon electrode, 99.9% acetonitrile containing 0.1 mol L−1 lithium perchlorate, SWV at the potential step of 1 mV, potential amplitude of 25 mV, and frequency of 25 Hz were decided as the most suitable working conditions. Nevertheless, the corresponding anodic peaks were not sufficiently separated due to their overlapping. Thus, four standard evaluation methods (polynomial or linear baseline, zero base, and deconvolution) were compared, and the last-mentioned method was chosen as optimum. Similar linear ranges from 3.0 × 10−6 to 1.0 × 10−5 mol L−1 were obtained for α, γ, and δ-tocopherol, characterized by determination coefficient of 0.998, 0.985, and 0.994, quantification limits of 11.28, 2.70, and 3.67 × 10−6 mol L−1 and detection limits of 3.72, 0.89, and 1.21 × 10−6 mol L−1, respectively. A recovery from 72.0 to 128.5% for different concetration ratios of tocopherols has been achieved. This recovery range is in the accordance with values reported for liquid chromatography.
Chemical and Energy Recovery Alternatives in SWRO Desalination through Electro-Membrane Technologies
Authors: Herrero-Gonzalez Marta , Ibañez Raquel
Published: September 2021

Electro-membrane technologies are versatile processes that could contribute towards more sustainable seawater reverse osmosis (SWRO) desalination in both freshwater production and brine management, facilitating the recovery of materials and energy and driving the introduction of the circular economy paradigm in the desalination industry. Besides the potential possibilities, the implementation of electro-membrane technologies remains a challenge. The aim of this work is to present and evaluate different alternatives for harvesting renewable energy and the recovery of chemicals on an SWRO facility by means of electro-membrane technology. Acid and base self-supply by means of electrodialysis with bipolar membranes is considered, together with salinity gradient energy harvesting by means of reverse electrodialysis and pH gradient energy by means of reverse electrodialysis with bipolar membranes. The potential benefits of the proposed alternatives rely on environmental impact reduction is three-fold: (a) water bodies protection, as direct brine discharge is avoided, (b) improvements in the climate change indicator, as the recovery of renewable energy reduces the indirect emissions related to energy production, and (c) reduction of raw material consumption, as the main chemicals used in the facility are produced in-situ. Moreover, further development towards an increase in their technology readiness level (TRL) and cost reduction are the main challenges to face.

In our modern, fast-paced life, plastic is a versatile material essential to our economy; daily life is unthinkable without it. However, there are serious downsides for the environment and health, which are becoming more and more stark in our society, and the recycling of plastic offers a partial solution to these widespread problems. The present work delves into the environmental assessment of fibre-reinforced concrete specimens, made with recycled plastic fibres from food packaging waste. Leaching tank tests for the evaluation of the long-term release of pollutant elements, identification of leaching mechanisms, and the diffusion process of contaminants into the environment were conducted on fibre reinforced concrete. The results showed that the incorporation of the recycled plastic fibres, classified as non-hazardous, did not release relevant levels of any potential harmful element incorporated in concrete. Moreover, low mobility was detected in the studied elements and different release mechanisms were identified through long-term diffusion leaching tests. Hence, the environmental feasibility of the incorporation of recycled plastic fibre in concrete was proven. This study strengthens the objectives set out by the Circular Economy Action Plan, which includes the European Strategy for Plastics and aims to, among other things, boost the market for recycled plastics.

Published: September 2021

Trains are used as the fastest mode of transportation for both people and cargo. The train moves along a special path called “rail”, where fatigue can be accumulated due to wheel-rail contact load as a result of continuous train operation. Consistent and regularly scheduled safety management is required since corrosion rate of the rails located on outside environment is very high. Researchers have actively investigated and developed rail defect inspection systems employing non-destructive techniques to address these problems. In particular, the eddy current inspection technique does not involve contact with the surface of the test specimen and offers the advantage of excellent rail defect detection sensitivity. Therefore, a 16 Channel array eddy current inspection device was developed to inspect the surface defects of the rail. An equation was derived to predict the correlation between the depth and phase of an artificial defect using the eddy current inspection device, and the derived equation was applied to the natural defect specimen.
