Application Of Artificial Intelligence For Temperature Profile Prediction In Additive Manufacturing Process
Authors: Shaikh Tauseef Ahmed , Amol D Lokhande , Sayyad Shafik R
Published: April 2022

Additive manufacturing (AM) is the computer-aided design for the successive addition of layers by layer material. It is widely used because of the fast prototyping using laser metal deposition, which is difficult to implement using conventional techniques. Understanding the temperature profile prediction is necessary in AM processes, such as Bed Fusion process (PBF) technology to produce the right quality parts. Thus, the temperature profile prediction using Artificial intelligence techniques, like data-driven models and real-time iterative models using complex geometries, require real time
control systems by considering the in-situ data. Besides, enhancing the accuracy of prediction is the hectic challenge faced by the existing systems. Hence, the proposed temperature profile prediction is developed based on an Artificial Intelligence
method named Global herding algorithm-based neural network (global herding-based NN) to overcome the challenges associated with the existing methods. The proposed global herding optimization is developed by hybridizing the herding characteristics associated with the standard Elephant herding optimization (EHO) and Rhino Herd (RH) optimization to boost the solution's global optimal convergence. Moreover, the integration of the proposed global herding optimization with the NN model ensures the optimal selection of the hyper-parameters of the NN classifier, which renders effective
performance of the temperature profile prediction. The effectiveness of the proposed model is revealed based on the performance metrics, such as MAE of 11.778, MAPE of 3.432, and MSE of 11.778.

Authors:   University of Niš, Faculty of Sciences, Mitić Milan , Mašković Pavle , Mitić Jelena
Published: April 2022

In this paper, extraction of the total flavonoid compounds from dill (Anethum graveolens L) leaves using an aqueous ethanol solution (50% by volume) was studied at different temperatures (30, 40, and 50 0C). A physical unsteady- state diffusion model and empirical Ponomarev model were developed to model the extraction process’s kinetics. The enthalpy and entropy changes were positive, while the Gibbs free energy was negative and decreased when temperature increased during the thermodynamic analysis. Therefore, extraction of total flavonoids from dill leaves was endothermic, spontaneous, and irreversible.

The aim of this study was to analyze the rhizosphere of duckweed as a site of active production of auxins of bacterial origin, primarily indole-3-acetic acid (IAA). IAA production was tested on 21 different bacterial strains. Four bacterial strains: Pseudomonas oryzihabitans 15, Pseudomonas putida 23, Hafnia paralvei 43 and Pseudomonas yamanorum 47 were selected based on increased IAA production compared to other strains tested. These strains showed continuous production of IAA even under unfavorable conditions: in acidic and basic environments, as well as in hypersaline environments. Our results suggest that these strains may have biotechnological applications in plant protection and increase yields through auxin production as central regulators of plant growth and development.

Published: April 2022

For millennia, berberine extracts or berberine itself has been the effective traditional drug with wide application due to its broad spectrum of antibiotic activity. A significant aspect of the berberine’s physiological activity that is often overlooked is the ability to go through the blood-brain barrier and has an impact on different processes and irregularities in the brain such as dementia and Alzheimer’s disease. Potential inhibitory activity towards enzymes for which is believed to be involved in these diseases, in this paper is confirmed by molecular docking simulations. Binding energies suggest that berberine exhibits good potential inhibitory activity and confirms that one of the aspects of suppression of Alzheimer’s disease and dementia is the inhibition of cholinesterase enzymes.

The aim of this study is to determine the qualitative and quantitative variability of volatile constituents of leaf essential oils of Cotinus coggygria Scop., wild-growing at three different types of the substrate; calcareous (3), serpentinite (2) and sandy (1). The essential oil samples were hydrodistilled from fresh leaves of C. coggygria. The obtained results showed that the leaf essential oils from all populations (i.e. regardless of the substrate on which they spontaneously grew) are abundant in monoterpene hydrocarbons (95.7%). Populations from calcareous and serpentinite habitats synthesize almost twice more oxygenated monoterpenes in their oils compared to that from the sandy substrate, while populations from serpentine and sandy substrates produce almost twice more sesquiterpene hydrocarbons than those from calcareous substrates. Therefore, it can be concluded that edaphic characteristics of natural stands of C. coggygria affect the composition of their leaf oils, which may have significant applications in biotechnology.

Authors: Jumriladin Putra Susila Dedhe , Yuliyanto Yuliyanto , Masdani Masdani
Published: April 2022

Saat ini belum adanya informasi mengenai kekuatan spesifik komposit serat karbon bermatriks polyester BQTN 157 membuat pentingnya melakukan pengujian material pada bahan komposit serat karbon bermatriks polyester BQTN 157 yang nantinya dapat diterapkan pada industri manufaktur dalam pembuatan produk pada industri tersebut. Adapun dalam pelaksanaanya penelitian ini menggunakan desain penelitan jenis eksperimental. Proses pembuatan komposit dibuat dengan metode hand lay up dengan panjang serat 20mm, 25mm dan 30mm dengan variasi serat 30%:70%, 40%:60% dan 50%:50% dengan orientasi serat 0°. Setelah spesimen selesai dibuat akan dilakukan curing time pada suhu 50°C selama 5 jam, 10 jam dan 15 jam. Spesimen uji tarik dibuat mengacu pada standar ASTM D-638 dan pengujian impak mengacu pada ISO-179. Kemudian patahan hasil uji tarik akan dianalisa dengan SEM (Scanning Electron Microscope). Hasil penelitian komposit polyester dengan penguat serat karbon diperoleh kekuatan tarik tertinggi terdapat pada fraksi volume serat 40% dengan panjang serat 33,41mm yaitu sebesar 135 MPa dan kekuatan impak maksimum dimiliki oleh komposit dengan fraksi volume serat 56,82% dan panjang serat 25mm yaitu sebesar 208,25 Mpa. Berdasarkan analisa dan perhitungan data yang diperoleh dari hasil pengujian yang dilakukan maka dapat diambil kesimpulan bahwa variasi fraksi volume dan panjang serat karbon dapat mempengaruhi sifat mekanik dari komposit polyester BQTN 157 berpenguat serat karbon. Kekuatan komposit naik seiring bertambahnya fraksi volume maupun panjang serat. Dari analisa SEM kekuatan material komposit dipengaruhi oleh kerapatan antara serat karbon dengan matriks. Ketidakrapatan menyebabkan adanya rongga (void) yang terbentuk antara serat dengan matriks. Semakin kecil rongga yang terbentuk maka menunjukkan semakin baik ikatan yang terjadi antara serat dengan matrik yang dibuktikan dengan kekuatan dari spesimen yang tinggi, begitu pula sebaliknya semakin besar rongga yang terbentuk maka menunjukkan ikatan yang kurang baik antara serat dengan matrik yang dibuktikan dengan kekuatan dari spesimen yang rendah. Hal ini menyebabkan nilai kekuatan disetiap komposit berbeda.

Published: April 2022

A kognitív pszichológia, a mozgással foglalkozó tudományok és a sportpszichológia területén megalapozott és széles körben elfogadott az a szemlélet, hogy a mentális reprezentációk tudatos használatára épülő technikák nagyban hozzájárulnak a szenzoros és motoros funkciók fejlődéséhez. Franklin módszere is megerősíti, hogy a belső képalkotás és koordinációs képességek korrelálnak. A tánc anatómiájában és a tánctudás fejlesztésében a vizualizáció technikája hidat képez. Jacobson neuromuszkuláris elmélete és Annett ALI modellje alapján az agyban megalkotott kép hatást gyakorol az izmok aktivitására, anélkül, hogy végrehajtanánk a mozdulatot. A vizualizáció segíti a mozdulatok jövőbeli megalkotását: a táncos mélyebben, több aspektusból megismeri a saját mozgását. Az imagináció során több modalitást is felhasználunk a belső kép létrehozásában, ezáltal hatékonyabb lehet a mozdulatsor kivitelezése. Ez a módszertani áttekintés Franklin technikájának részletes elméleti és gyakorlati bemutatását tartalmazza. A kreatív gyermektánc alkalmazása előnyös lehet a vizualizációs technikák előkészítésére. A szerzők javasolják a technika táncpedagógiai alkalmazását minden életkorban.
Application of Mental Practices of the Franklin Method in Dance Education
Authors: Grecsó Zoltán , Szászi Beáta
Published: April 2022

Cognitive psychology, motion sciences and sport psychology widely accept the approach that technologies based on the intended use of mental representations significantly contribute to the development of sensory and motor functions. The method of Franklin also confirms that internal imaging and coordination capabilities correlate. In the anatomy of dance and the development of dance skills, visualization forms a bridge. Based on Jacobson's neuromuscular theory and Annett's ALI model, the image created in the brain impacts the activity of the muscles without performing the movement. Visualization helps to create future movements. The dancer learns his/her motion more deeply from multiple aspects. Throughout imagination, we use several modalities to create the internal image. Due to this process, it will be more effective to implement the movement sequence. This methodological overview contains a detailed theoretical and practical presentation of Franklin's technique. The use of creative children’s dance may be advantageous for preparing visualization techniques. The authors recommend the dance pedagogical application of these tools at all ages.

Published: April 2022

This paper considers the problem creation of an operating system automated control system for the Naval Forces of the Armed Forces of Ukraine from the point of view of the peculiarities of scenarios of its load in accordance with the real situation.
The authors focused on the fact that modern technical solutions that implement the most advanced developments in science and technology regarding the construction of modern automated control systems, in their content, do not cover the assessment of the ability of existing operating systems as a basic complex of interconnected programs for full-fledged control of the hardware component of the control system, ensuring control of the computing process and organizing its full-fledged interaction with users.
Special attention was focused on the architecture of the real-time operating system, the main purpose of which is to provide the necessary and sufficient set of functions for the design, development and operation of real-time systems on specific hardware in our case, in a conditional data processing center (of the corresponding level) of the automated control system of the Naval Forces of the Armed Forces of Ukraine.
The real-time operating system of the automated control system (ACS) of the Naval Forces of Ukraine must have a hybrid core that implements the connection between application processes and hardware, a basic set of applications, system libraries and maintenance programs.
The advantages of this particular architecture are: increased reliability (each service is essentially an independent process that is easier to debug and track errors that occur), improved scalability (unnecessary services can be excluded from the system without material damage to its performance), increased fault tolerance and others.
In this aspect, when the ACS data processing center will operate with a sufficiently large flow of service requests, it is quite appropriate to use the apparatus of the Queuing system theory.

In order to meet the needs of the Armed Forces of Ukraine (AFU) for specialists in the operation of unmanned aerial systems, the Zhitomir Military Institute named by S. P. Korolev deployed training for operators - military pilots. While creating the material and technical base, the issue of developing and introducing into the training process of simulators that would meet the requirements of higher military education training. Development of the scientific training system was carried out on the basis of the list of basic training issues, profound mastery of which is mandatory for the UAV operator’s. The training system was developed, manufactured and implemented in the training process, which is built as a schematic-abstracted one to ensure the conditions of effective learning material assimilation. The content basis of the scientific training system is a flat schematic outline of the aircraft, which contains typical onboard equipment of unmanned aerial vehicles and a reconstructed connection scheme of the elements. The power of the onboard equipment is provided from the classroom power supply via a stabilized power supply unit. Operation of the onboard equipment can be controlled from the manual control panel and from the ground control station via the Mission Planner program. The Mission Planner can also be controlled from the X - Plane flight simulator. In flight simulation mode, the Mission Planner screen displays a map of the flight route, the X-Plane screen displays the view and spatial orientation as well as the corresponding servo drives of the aircraft's steering surfaces and the main engine operation modes. The software of the scientific training system allows planning and adjusting the route and flight program, practicing UAV piloting skills in the flight simulator mode, simulating flight in different weather conditions. The scientific training system includes a two-channel hardware-software oscilloscope which allows to research electric processes in different electric lines of airborne equipment of the aircraft and pair interconnections between them. Functional properties of scientific training system allow to study theoretically and practice practically a wide range of training issues required in training of UAV operators. Up to this circle includes both the issues necessary for mastering drone piloting and the issues necessary for mastering the maintenance and repairs of UAV.

Authors:   Sharif medical and Dental College, Lahore, Fatima Arooj
Published: April 2022

Introduction: Oxygen radical injury is thought to be one of the common mechanisms for several diseases in premature infants. Lipid peroxidation plays a vital role in the pathogenesis of many neonatal complications. Broncho pulmonary dysplasia, Intraventricular hemorrhage and Retinopathy of Prematurity are due to excessive production of oxygen free radicals. Objectives: The main objective of the study is to find the Malondialdehyde (MDA), total antioxidant capacity and Vitamin E levels in preterm and term infants. Material and methods: We aimed to determine the levels of Malondialdehyde (MDA), Total antioxidant capacity and vitamin E in cord blood of term and preterm infants. To determine the oxidative stress and antioxidants in cord blood of term and preterm infants that may have clinical implications. In the present study we determine MDA, Total antioxidant capacity and vitamin E levels in the umbilical cord blood of term (n=50) and preterm (n=50) infants by manual method. Blood samples were collected during delivery. MDA is high in preterm infants compared to term infants. Results: Total antioxidant capacity and Vitamin E levels are high in term infants compared to preterm infants. Therefore it is possible to postulate that preterm infants are more susceptible to oxidative stress than term infants. Conclusion: It is concluded that Preterm neonates are exposed to increased oxidant stress at birth and are susceptible to anti-oxidant deficiencies.

of the world. Objectives: The main objective of the study is to find the haematological parameters and oxidative stress in malarial patients. Material and methods: This cross sectional study was conducted in THQ Hospital Fort Abbas Bhawalngar during 2020 to 2021. The data was collected from 200 male and female patients. Participants remembered for the review were under-5-year-old youngsters, either conceded in the kids’ ward or going to any center on short term premise. Results: The information was gathered from 200 malarial patients. There was a genuinely huge decrease in hemoglobin (p<0.005), platelet count (p<0.001) and all out leukocyte count (p<0.001) levels in patients with malaria contrasted with patients without the sickness. The level of neutrophils in the subjects with malaria was fundamentally higher (p<0.005) than in the non-malaria bunch. Conclusion: It is inferred that Low platelet count is a trademark finding of malarial contamination and thrombocytopenia might be more normal than weakness in intense malaria disease.

Citizen Participation is an essential element in achieving sustainable community across the globe. However, in many countries, the execution of citizen participation is not optimal due to various constraints such as development goals and administrative power. Malaysia is no exception in that matter. Therefore, this paper seeks to investigate the extent of citizen participation in the Malaysian context during 2010-2020. The desk research method was applied, and data was collected through a literature review. The retrieved information was analysed using thematic analysis. This study verified that Malaysian’s participation is at tokenism level of Arnstein’s ladder of participation. The findings showed that execution of citizen participation in public project or program need to be improvised. This study recommends government, thru its authorities, to boost citizen participation in a public project utilizing various efficient engagement methods.
Agricultural Techniques and Impacts on Biodiversity
Authors: Onana Tunde Tolo
Published: April 2022

This study aims to objectify the impact of the use of traditional agricultural techniques on biodiversity, in particular on the disappearance of plant and animal species. The data presented here come from a socio-environmental survey conducted in the central Moungo region in 2013-2014 and whose data collection was done through questionnaires, field observations and semi-structured interviews. The analysis of maps of the region at different periods (2001, 2007, and 2013) in order to understand the evolution of the vegetation cover completed our methodology. From the analysis of the data, it appears that the agricultural techniques used (slash-and-burn agriculture, plowing, regular polyculture, excessive use of pesticides) by farmers in Mélong have an impact on biodiversity in that they contribute to the decline of vegetation, soil depletion and the disappearance of certain plant and animal species. In conclusion, we believe that farmers should take their environment into account when developing their farming techniques, and thus practice sustainable agriculture.
