At the beginning of 2023, Łukasiewicz Research Network – Institute for Ferrous Metallurgy (Łukasiewicz – IMŻ) begins its activity in the structure of a new institute under the name of Łukasiewicz Research Network – Upper Silesian Institute of Technology, after consolidation with Łukasiewicz – Institute of Welding and Łukasiewicz – Institute of Electrical Drives and Machines KOMEL.
On the eve of this change, this study presents the research achievements of Łukasiewicz – IMŻ in 2022 and the topics planned to be undertaken in 2023. It takes into account projects financed from the national and EU budget for science, as well as the significant involvement of the Institute in the implementation of applied projects that contribute to increasing the innovativeness of the domestic industry, including the energy and defence sectors. Attention was paid to the dynamically developing new hydrogen technologies in metallurgy, additive technologies and high-temperature material characteristics, important for the aerospace industry.
At the same time, we would like to announce that the current issue of “Journal of Metallic Materials” is the last issue of our quarterly, publishing original research results in the field of metallurgy, materials engineering, chemistry, environmental protection and management in the iron and steel industry. Its traditions date back to 1949, when the first issue of the journal was published under the title “Prace Badawcze Głównego Instytutu Metalurgii i Odlewnictwa (Research Works of the Central Institute of Metallurgy and Casting)”. In 1976-2018, the quarterly was published under the title “Prace Instytutu Metalurgii Żelaza (Works of the Institute for Ferrous Metallurgy)”. The title changed to the current one in 2019. On behalf of the entire editorial team, we would like to thank all readers and authors of articles and reviewers for their cooperation. The establishment of the new Institute will certainly create conditions for the continuation of publishing activities in a broader substantive scope.

Cancer encompasses a group of chronic pathologies with multifactorial causes and high levels of mortality in Brazil and worldwide. In addition, they constitute diseases with a great impact on the morbidity and mortality of patients and a high burden for the health system. Thus, the research seeks to outline the epidemiological profile of cancer in the state of Amapá from January 2018 to March 2021. For this, a descriptive, retrospective, cross-sectional study was used based on secondary public data from the “Panel Oncologia” , obtained from the Department of Informatics of the Unified Health System (DATASUS)[10]. A total of 610 cases were analyzed, of which 52.8% were male patients, with an emphasis on the age group of 65-69 years. Comparing the types of cancer, the most reported were breast (21.9%), prostate (18.5%) and stomach (12.9%). As for the establishment, the Hospital das Clínicas Doutor Alberto Lima (HCAL) was the health service that most diagnosed cases of malignant lesions in the state (90.3%) and the CRIO/CE unit was the location that received the highest number of cases patients treated outside the home (46.15%). It is concluded that cancer has a relevant prevalence in the population studied in the Amazon and knowledge of the epidemiological picture will enable better planning and disease control strategies and the prioritization of health promotion and prevention actions.

Published: January 2023

Os vírus linfotrópicos de células T humana (HTLV) foram os primeiros onco-retrovírus identificados em humanos. O vírus da imunodeficiência humana (HIV) é o agente etiológico da doença que atua no sistema imunológico, que pode acarretar na Sindrome da imunodeficiência Humana (Aids). A coinfecção pelo HTLV em indivíduos infectados pelo HIV ocorre pelo fato destes vírus compartilharem vias de transmissão similares, seja por via sexual, parenteral ou vertical, além de infectarem o mesmo tipo de célula. Os pacientes coinfectados podem apresentam evolução desfavorável das doenças. Objetivo: O presente estudo visa descrever sobre a coinfecção do Vírus Linfotrópico de células T Humanos (HTVL) em pacientes com HIV/Aids. Trata-se de um estudo de caráter descritivo, tipo revisão narrativa da literatura, norteada por artigos das principais bibliotecas virtuais e manuais do ministério da saúde. A coinfecção no Brasil foi inicialmente descrita no final da década de 80; essa coinfecao pode aumentar a expressão das doenças associadas ao HTLV-I, que passaria de < 1% entre não coinfectados para aproximadamente 20% a 25% naqueles coinfectados, durante a vida. Portadores do HTLV-1 apresentam risco de cerca de 1% para desenvolvimento de uma mielopatia ao longo da vida, assim como de LLcTA; porém, estudos indicam que indivíduos coinfectados HIV/HTLV têm um risco maior de doença neurológica ou talvez um curto período de incubação do HTLV. A carga viral do HTLV-I não é afetada pelo HIV, como a carga viral do HIV não é alterada pelo HTLV. Portando os estudos destacam que a coinfecção por retrovírus HTLV-I ou HTLV-II e HIV tem sido associada a maior probabilidade de desenvolvimento de doenças. Necessita de mais pesquisas para entender a real modificações no cursos dessas moléstias no organismo humano.
Wissen kompakt, Künstlicher Auftrieb: Mehr Power für die biologische Kohlenstoffpumpe des Meeres
Authors:   CDRmare
Published: January 2023

Algen, Zooplankton und Fische gehören zu den Schlüsselakteuren der biologischen Kohlenstoffpumpe, mithilfe derer der Ozean der Atmosphäre auf natürliche Weise Kohlendioxid entnimmt und den enthaltenen Kohlenstoff in großen Wassertiefen einlagert. Damit dieser Mechanismus jedoch optimal funktioniert, braucht es Nährstoffe, die vielerorts fehlen, zumindest im lichtdurchfluteten Oberflächenwasser. Durch das Heraufpumpen nährstoffreichen Tiefenwassers könnte der Mensch diesen Nährstoffmangel beheben. Ob ein solcher künstlicher Auftrieb aber tatsächlich klimawirksam wäre, welche Risiken er mit sich brächte und ob er technisch und rechtlich im großen Stil umgesetzt werden könnte, ist bislang ungewiss. Die Forschungsmission CDRmare liefert Antworten.

Conserving Biodiversity: A Public Health Imperative
Authors: Landman K. , Elton Sarah
Published: January 2023

[From Introduction]: "Biological diversity can be defined as “the variety of life on Earth, from the tiniest insect to a vast northern forest. Biodiversity is also about being connected – no species, including people, can live without others to provide it with food and habitat. All living things are part of this life system” (Ontario Biodiversity Council, 2016). 

There is an intrinsic connection between human health and wellbeing and biodiversity (Figure 1). Ontario’s Biodiversity Strategy builds on this connection: “Our vision is a future where biodiversity loss is halted and recovery is advanced. People value, protect and enhance biodiversity and the ecosystem services essential for human health and wellbeing.” (Ontario Biodiversity Council, 2011) However, many people, including health professionals, don’t fully appreciate how biodiversity supports our quality of life and our health in this province."  
Noninvasive tissue temperature estimation using nonlinear ultrasound harmonics
Authors: Maraghechi Borna , Kolios Michael , Tavakkoli Jahangir (Jahan)
Published: January 2023

Non-invasive tissue temperature estimation is important in thermal therapies for having an efficient treatment. A noninvasive ultrasonic technique for monitoring tissue temperature changes is proposed based on the changes in the harmonics of ultrasound backscatter as a function of temperature. The backscattered pressure amplitudes of the fundamental frequency (p1), the second (p2) and the third (p3) harmonics generated by nonlinear ultrasound propagation and the ratios of the second and the third harmonics over the fundamental frequency (p2/p1 and p3/p1) were investigated as a function of temperature. The acoustic harmonics were generated and detected with a commercial high frequency ultrasound imaging system in pulse-echo mode. The experiments were performed on tissue-mimicking gel phantoms and ex vivo bovine muscle tissues. The temperature was increased from 26°C to 46°C in increments of 2°C. The average values of p1, p2, p3, p2/p1, p3/p1 increased by 14%, 50%, 117%, 37% and 92% for the gel phantoms, and for the tissue samples increased by 29%, 50%, 170%, 10% and 109%, respectively. The results indicate that the harmonic amplitudes and their ratios are highly sensitive to propagation medium’s temperature and could potentially be used for noninvasive ultrasound thermometry
A Lattice-Boltzmann model to simulate diffractive nonlinear ultrasound beam propagation in a dissipative fluid medium

Published: January 2023

Ultrasound waves have been widely used in diagnostic and therapeutic medical applications. Accurate and effective simulation of ultrasound beam propagation and its interaction with tissue has been proved to be important. The nonlinear nature of the ultrasound beam propagation, especially in the therapeutic regime, plays an important role in the mechanisms of interaction with tissue. There are three main approaches in current computational fluid dynamics (CFD) methods to model and simulate nonlinear ultrasound beams: macroscopic, mesoscopic and microscopic approaches. In this work, a mesoscopic CFD method based on the Lattice-Boltzmann model (LBM) was investigated. In the developed method, the Boltzmann equation is evolved to simulate the flow of a Newtonian fluid with the collision model instead of solving the Navier-Stokes, continuity and state equations which are used in conventional CFD methods. The LBM has some prominent advantages over conventional CFD methods, including: (1) its parallel computational nature; (2) taking microscopic boundaries into account; and (3) capability of simulating in porous and inhomogeneous media. In our proposed method, the propagating medium is discretized with a square grid in 2 dimensions with 9 velocity vectors for each node. Using the developed model, the nonlinear distortion and shock front development of a finiteamplitude diffractive ultrasonic beam in a dissipative fluid medium was computed and validated against the published data. The results confirm that the LBM is an accurate and effective approach to model and simulate nonlinearity in finite-amplitude ultrasound beams with Mach numbers of up to 0.01 which, among others, falls within the range of therapeutic ultrasound regime such as high intensity focused ultrasound (HIFU) beams. A comparison between the HIFU nonlinear beam simulations using the proposed model and pseudospectral methods in a 2D geometry is presented

Authors: Karaderi Şefika , Duman Ümran
Published: January 2023

Cyprus has hosted many cultures and civilizations for centuries. Thanks to these civilizations, architectural structures of different styles are seen together in Cyprus. Nicosia's walled city, which started with the Lusignan period and took its current form during the Venetian period, is home to some of these structures. Although very few of the ones that have survived are used in the function of the period in which they were built, most of them have been re-functionalized. In addition, while some of them are idle, some of them have been preserved and used. Despite the touristic interest and socio-cultural activities in the region, the unused buildings have brought various negativities to the urban structure.Over time, with the increasing interest of the individuals living in the city in the historical texture, the re-functioning and use of these structures have gained importance. In this context, Zahra Street, which is among the urban spaces with an important location and architectural structures bordering the Buffer Zone within the city wall of the divided capital Nicosia, was chosen as the study area. The use of the British Period residences here with the function of a cafe today has contributed socio-culturally to the city walled area of the developing city of Nicosia. Effective use has been achieved thanks to adaptive reuse in the region where traces of past life are found in contemporary living conditions. Thus, a more livable, safe and pleasant urban space has been obtained. This study, it is aimed to emphasize the importance of improvement in urban spaces when they are reused in accordance with the changing living conditions depending on human needs. A literature review was conducted on the subject and data were collected using qualitative and quantitative methods during the on-site inspection. The facades, entrance hall/service area, sitting areas, toilets and outdoor/courtyard sections were examined in the tables created for each building with the collected data. According to the research, it can be said that successful re-use was applied to the cafe function while it was a residential function.

Published: January 2023

This paper aims to explain the effect of workplace respect on employee performance at Abu Ghraib Dairy Factory (AGDF). For achieving the research aim, the analytical and descriptive approach was chosen using a questionnaire tool for collecting data.  It covers 22 items; ten of them for the workplace respect variable and twelve items for the employee performance variable. The research population involved human resources who work at AGDF in Baghdad within two administrative levels (top and middle). We conducted a purposive stratified sample approach. It was distributed 70 questionnaire forms, and 65 forms were received. However, six of them had missing data and did not include in the final data analysis. The main results are that there is a positive significant effect of workplace respect on job performance. Moreover, workplace respect appears in AGDF through forgiving honest mistakes of workers. Furthermore, the sub-variable of the knowledge of work requirements ranked first in terms of availability, practice, attention, and adoption. Then followed by the dimensions (performance quality, the spent effort, and completed work) respectively. This can be understood that the availability of the three sub-variables combined has led to the factory owning a set of behaviors and functional activities.

Published: January 2023

Missing values in the time-series data set have an impact on the correct decision-making in the future. Since complete data helps to obtain high accuracy in the estimation process, the reason for missing values is a malfunction of the measuring device or an error in the data entry process by the person. The research aims to compare the radial basis function methods with other methods to estimate missing values in univariate time series data. the simulation method was used to compare the methods to estimate the missing values, and that was used the Box-Jenkins model AR(1) once with the value of  and once with the value of  and with different sample sizes (60,100,300), assuming four percentages of missing from data values are missing at random MAR (5%,10%,15%,20%). The accuracy of the estimation of the methods was evaluated by using the standard of accuracy, the mean sum of squares error (MSE). from the results obtained using simulation, it was found that the(RBF) method is the best method for estimating the missing values in both values, in all sizes, and all loss ratios because it produces the lowest value of the average square error compared to other methods.

Authors: Joudah Irshayyid Ahmed , Abdulrida Saleh Rabab
Published: January 2023

One-parameter exponential regression is one of the most common and widely used models in several fields, to estimate the parameters of the one-parameter exponential regression model use the ordinary least square method but this method is not effective in the presence of outlier values, so robust methods were used to treat outlier values in the one-parameter exponential regression model are to estimate the parameters using robust method (Median-of-Means, Forward search, M-Estimation), and the simulation was used to compare between the estimation methods with different sample sizes and assuming four ratios from the outliers of the data (10%, 20%, 30%, 40%). And the mean square error (MSE) was made to reach the best estimation method for the parameters, where the results obtained using the simulation showed that the forward search is the best because it gives the lowest mean of error. On the practical side, expenditure and revenue data were used to estimate the parameters of the one-parameter exponential regression, where the data was tested, it appeared to have an exponential distribution, and the boxplot and (COOK) test were used to detect the outliers present in the real data. The Goodness of fit test was used for the one-parameter exponential model, and it was found that the data did not follow the normal distribution, and it was found that it suffers from the problem of heterogeneity of variance. The one-parameter exponential regression model for the expenditure and revenue data was estimated using the advanced search method because it was the best estimate.

Comparison of Robust Circular S and Circular Least Squares Estimators for Circular Regression Model using Simulation
Authors: Hadib Abbas Huda , Najim Abood Suhail
Published: January 2023

In this paper, the Monte-Carlo simulation method was used to compare the robust circular S estimator with the circular Least squares method in the case of no outlier data and in the case of the presence of an outlier in the data through two trends, the first is contaminant with high inflection points that represents contaminant in the circular independent variable, and the second the contaminant in the vertical variable that represents the circular dependent variable using three comparison criteria, the median standard error (Median SE), the median of the mean squares of error (Median MSE), and the median of the mean cosines of the circular residuals (Median A(k)). It was concluded that the method of least squares is better than the methods of the robust circular S method in the case that the data does not contain outlier values because it was recorded the lowest mean criterion, mean squares error (Median MSE), the least median standard error (Median SE) and the largest value of the criterion of the mean cosines of the circular residuals A(K) for all proposed sample sizes (n=20, 50, 100). In the case of the contaminant in the vertical data, it was found that the circular least squares method is not preferred at all contaminant rates and for all sample sizes, and the higher the percentage of contamination in the vertical data, the greater the preference of the validity of estimation methods, where the mean criterion of median squares of error (Median MSE) and criterion of median standard error (Median SE) decrease and the value of the mean criterion of the mean cosines of the circular residuals A(K) increases for all proposed sample sizes. In the case of the contaminant at high lifting points, the circular least squares method is not preferred by a large percentage at all levels of contaminant and for all sample sizes, and the higher the percentage of the contaminant at the lifting points, the greater the preference of the validity estimation methods, so that the mean criterion of mean squares of error (Median MSE) and criterion of median standard error (Median SE) decrease, and the value of the mean criterion increases for the mean cosines of the circular residuals A(K) and for all sample sizes.
THE LEGALITY OF SELECTIVE REDUCTION IN MULTIPLE PREGNANCIES DURING INFERTILITY TREATMENT OF COUPLES: THE CASE STUDY OF IRANIAN LAW
Authors: Hashemi Nasab Zavareh Mohsen
Published: January 2023

Even if the Medical Abortion and Embryo Donation Acts approved in 2002 by the Iranian Legal System can be exploited to treat infertility among couples in Iran, selective reduction as one of the most commonly used procedures, has been declared illegal by Shiite jurists due to the expulsion of a number of embryos. Given that physicians destroy the weak embryos in multiple pregnancies in order to help the strong one in selective reduction between the 10th and 13th gestational weeks, and the existing laws on infertility treatments are not up-to-date or do not comply with new methods, including selective reduction, infertile couples have been facing many problems. Accordingly, the rights in infertility treatments in Iran, require more comprehensive and new legislations by pointing out the restrictions and legalities in the law, without stipulating a specific method. Upon making the law in this line, judges can deal with the requests filed by couples in each case separately, and according to the legal restrictions, and then issue a verdict regarding treatments demanded, by taking account of all new infertility treatment methods. This study reflects on the arguments against the multifetal pregnancy reduction (MFPR) in Iran, before going over the Medical Abortion and Embryo Donation Acts for Iranian infertile couples. With regard to the illegality of some infertility treatments, this study provides solution that can be consider by the legislator especially in Iran, and can be reviewed by other countries as a case study.

This paper presents a very prominent thermal technology that could overcome mentioned deficiencies of raw biomass. This technology is known as torrefaction. Torrefaction is mainly used to convert lignocellulosic materials into 'fuels' that can be used in power plants, combustion units, or gasifiers.
Artificial Intelligence-based Prediction of In Vitro Dissolution Profile of Immediate Release Tablets with Near-infrared and Raman Spectroscopy
Authors: Péterfi Orsolya , Nagy Zsombor Kristóf , Sipos Emese , Galata Dorián László
Published: January 2023

The objective of the present work was to develop an artificial neural network (ANN) model to accurately predict the dissolution profile of immediate release tablets based on non-destructive spectral data. Six different tablet formulations with varying API (caffeine) and disintegrant (potato starch) concentrations were prepared. The near-infrared (NIR) and Raman spectra of each tablet were collected in both reflection and transmission modes, then principal component analysis (PCA) was conducted. The training of the ANN was performed at each hidden neuron number from 1 to 10 in order to determine the optimal number of neurons in the hidden layer. The best results were obtained when a small number of neurons (1–3) was used. In the case of all four spectroscopic methods, the average similarity values (f2) of the optimized ANN models were above 59 for the validation tablets, indicating that the predicted dissolution profiles were similar to the measured dissolution curves. The optimized model based on reflection Raman spectra exhibited the best predictive ability. The results demonstrated the potential of ANN models in the implementation of the real-time release testing of tablet dissolution.

A quintessential setting for precision medicine, theranostics refers to a rapidly evolving field of medicine in which disease is diagnosed followed by treatment of disease‐positive patients using tools for the therapy identical or similar to those used for the diagnosis. Against the backdrop of only‐treat‐when‐visualized, the goal is a high therapeutic index with efficacy markedly surpassing toxicity. Oncology leads the way in theranostics innovation, where the approach has become possible with the identification of unique proteins and other factors selectively expressed in cancer versus healthy tissue, advances in imaging technology able to report these tissue factors, and major understanding of targeting chemicals and nanodevices together with methods to attach labels or warheads for imaging and therapy. Radiotheranostics—using radiopharmaceuticals—is becoming routine in patients with prostate cancer and neuroendocrine tumors who express the proteins PSMA (prostate‐specific membrane antigen) and SSTR2 (somatostatin receptor 2), respectively, on their cancer. The palpable excitement in the field stems from the finding that a proportion of patients with large metastatic burden show complete and partial responses, and this outcome is catalyzing the search for more radiotheranostics approaches. Not every patient will benefit from radiotheranostics; but, for those who cross the target‐detected line, the likelihood of response is very high.

Hearing in neonates and infants is crucial for their development of language and communication skills. Unless hearing loss is appropriately managed early, it can cause a significant socioeconomic burden considering its detrimental impact on the child's development and its common nature. It is also the most common congenital sensory deficit, with an approximate incidence of 1.5 per 1,000 newborns. Its etiologies are heterogeneous: genetic causes are reportedly involved in up to 80% of cases, while congenital cytomegalovirus infection is the leading environmental factor contributing to congenital hearing loss. The introduction of newborn hearing screening using automated auditory brainstem response and/or automated otoacoustic emission in many developed countries has helped detect and manage hearing loss early. Current auditory rehabilitation options such as cochlear implantation implementing cutting-edge technologies can treat almost all degrees of hearing loss, emphasizing the importance of early hearing detection and intervention. Rapidly developing genetic diagnostic technologies and future cutting-edge treatment options, including gene therapy, will shed light on the future management of hearing loss in neonates and infants.

The amniotic membrane (AM) is the inner part of the placenta. It has been used therapeutically for the last century. The biological proprieties of AM include immunomodulatory, anti-scarring, anti-microbial, pro or anti-angiogenic (surface dependent), and tissue growth promotion. Because of these, AM is a functional tissue for the treatment of different pathologies. The AM is today part of the treatment for various conditions such as wounds, ulcers, burns, adhesions, and skin injury, among others, with surgical resolution. This review focuses on the current surgical areas, including gynecology, plastic surgery, gastrointestinal, traumatology, neurosurgery, and ophthalmology, among others, that use AM as a therapeutic option to increase the success rate of surgical procedures. Currently there are articles describing the mechanisms of action of AM, some therapeutic implications and the use in surgeries of specific surgical areas, this prevents knowing the therapeutic response of AM when used in surgeries of different organs or tissues. Therefore, we described the use of AM in various surgical specialties along with the mechanisms of action, helping to improve the understanding of the therapeutic targets and achieving an adequate perspective of the surgical utility of AM with a particular emphasis on regenerative medicine.
