Published: April 2023

Background:

Plasma cell neoplasms are characterized by the neoplastic proliferation of a single clone of plasma cells. Solitary plasmacytomas most often occur in bone, but they can also be found in soft tissues.

Case Description:

A 53-year-old male presented with localized sacral pain and urinary incontinence. His radiographic studies showed a solitary sacral plasmacytoma (i.e., involving the bone). He was successfully managed with high-dose dexamethasone and microwave ablation (MWA).

Conclusion:

Plasmacytomas of bone can be occasionally successfully managed with MWA, adjuvant cytoreduction therapy, and high doses of dexamethasone.
A case report of conus intramedullary mansoni neuroschistosomiasis
Authors: Mohandas Prithvi , Sarkar Hrishikesh , Jain Deepti , Sundaram Vanaja Kate Garfin
Published: April 2023

Background:

Conus schistosomiasis is an extremely rare entity in which patients present with a wide range of neurological symptoms such as low back pain, paresthesia, fever, myalgia, paraparesis, and paraplegia. This neglected tropical parasitic disease causes significant neurological morbidity. The migration of parasitic worms and their eggs into the central nervous system can lead to profound and life-altering disabilities. Early, accurate diagnosis, and treatment can lead to the complete resolution of symptoms.

Case Description:

A 5-year-old boy from South Sudan presented with complaints of sudden onset, progressive bilateral lower limb weakness for the past month, inability to walk or stand without assistance, and urinary incontinence. Magnetic resonance imaging spine showed an irregular enhancing lesion within the conus. The various possibilities, such as Astrocytoma, and granulomatous disorders were considered. However, a biopsy revealed the lesion to be Conus schistosomiasis, a rare condition with only a few cases reported in children. Typical clinicoradiological presentation and the treatment paradigm have been discussed in this manuscript. Appropriate management of this lesion can avert surgical intervention needed for either a diagnosis or treatment.

Conclusion:

This case report aims to emphasize the importance of considering schistosomiasis as an important differential diagnosis of a conus intramedullary lesion, especially in patients from tropical endemic countries. The neurological recovery in this infestation is directly related to early diagnosis and treatment. Therefore, it is essential to recognize this entity, as early detection and management would result in significant neurological improvement without undergoing surgery.
Rapid mapping of alloy surface phase diagrams via Bayesian evolutionary multitasking
Authors: Han Shuang , Lysgaard Steen , Vegge Tejs , Hansen Heine Anton
Published: April 2023

Surface phase diagrams are essential for understanding the dependence of surface chemistry on reaction condition. For multi-component systems such as alloys, the derivation of such diagrams often relies on separate global optimization tasks under different reaction conditions. Here we show that this can be significantly accelerated by leveraging the fact that all tasks essentially share a unified configurational search space, and only a single expensive electronic structure calculation is required to evaluate the stability of a surface structure under all reaction conditions. In particular, we present a novel Bayesian evolutionary multitasking (BEM) framework combining Bayesian statistics with evolutionary multitasking, which allows efficient mapping of surface phase diagrams for very complex heterogeneous systems. As proofs of concept, we showcase the performance of our methods in deriving the alloy surface phase diagrams for two heterogeneous catalytic systems: the electrochemical oxygen reduction reaction (ORR) and the gas phase steam methane reforming (SMR) reaction.

Authors: Robles-Remacho* Agustín , Sanchez-Martin Rosario M. , Diaz-Mochon* Juan J.
Published: April 2023

Spatial transcriptomics technologies are providing new insights to study gene expression, allowing researchers to investigate the spatial organization of transcriptomes in cells and tissues. This approach enables the creation of high-resolution maps of gene expression patterns within their native spatial context, adding an extra layer of information to bulk sequencing data. Spatial transcriptomics has expanded significantly in recent years and is making a notable impact on a range of fields, including tissue architecture, developmental biology, cancer, neurodegenerative and infectious diseases. The latest advancements in spatial transcriptomics have resulted in the development of highly multiplexed methods, transcriptomic-wide analysis, and single-cell resolution, utilizing diverse technological approaches. In this perspective, we provide a detailed analysis of the molecular foundations behind the main spatial transcriptomics technologies, including methods based on microdissection, in situ sequencing, single-molecule FISH, spatial capturing, selection of regions of interest and single-cell or nuclei dissociation. We contextualize the detection and capturing efficiency, strengths, limitations, tissue compatibility, and applications of these techniques, as well as provide information on data analysis. In addition, this perspective discusses future directions and potential applications of spatial transcriptomics, highlighting the importance of the continued development to promote widespread adoption of these techniques within the research community.

The seed-mediated growth of gold nanostructures is known to be intensely dependent on the gold seed nanocrystal structure but also in the presence of different additives that may influence the morphology and, therefore, the crystalline structure of the final nanoparticle. Among the different additives or capping ligands, biomolecules are an exciting family due to their potential biomedical applications, such as drug delivery, bioimaging, biosensing, phototherapy, and antimicrobial activities. Here, we develop a seed-mediated strategy for synthesizing uniform Au nanostars with tuneable optical properties that involve adenosine monophosphate (AMP) as a capping ligand. The experimental data reveal the key role of AMP, not just providing colloidal stability and directing the reduction of the gold precursor via complexation but also mediating the anisotropic growth of the Au seeds via its selective adsorption on the different crystalline facets of Au nanoparticles. These observations agree with theoretical simulations carried out using molecular dynamics and density functional theory (DFT) calculations. Interestingly, the obtained Au nanostars showed high thermal and colloidal stability in polar organic solvents, which allowed their direct silica coating via the Stöber method. Importantly, we also explored the mimic enzymatic activity of the resulting gold nanostars and observed a superior catalytic activity compared with the other gold nanoparticles reported in the literature.

Published: April 2023

In this work we seek to understand the pre-catalystic initiation steps between two metallaphotoredox catalysts Ir(III) ((Ir[dF(CF3)ppy]2}(dtbbpy))PF6) and Ni(II) ((4,4'-dtbbpy)NiCl2) using a combination of X-ray and optical spectroscopies. We observe two steps: first, photoexcitation produces the expected intramolecular oxidation of Ir(III) to Ir(IV)(dtbbpy)•- correlated to the Ir metal-to-ligand charge transfer state, rather than Ir(II) which is often reported in literature. Second, the 4-coordinate Ni(II) starting species evolves to a 6-coordinate Ni(II) species after oxidation by Ir(IV)(dtbbpy)•-. We conclude by proposing the identity of the 6-coordinate Ni(II) species and its potential importance in the pre-mechanistic step prior to Ni entering the catalytic cycle. This neglected 6-coordinate Ni(II) intermediate could help to unravel the poorly understood initiation step in these metallaphotoredox C_sp3-C_sp2 cross-coupling reactions.

Background and objectives Thrust manipulation Manipulation and non-thrust manipulation Mobilization have already made a mark in improving pain disability and range of motion in patients with mechanical neck pain. The objective of the present study was to compare the effectiveness of thrust manipulation versus nonthrust manipulation in mechanical neck pain.Methods Thirty patients with mechanical neck pain were randomly assigned into two groups ndash subjects in Group A n15 were treated with Transverse thrust manipulation at C6 level while subjects in Group B n15 were treated with Postero-anterior mobilization at C6 level. Treatment dosage for both groups was two sessions or one week duration. Pain intensity Range of Motion ROM Neck disability were evaluated pre and post each session. Numerical Pain Rating Scale NPRS Goniometer and Neck Disability Index NDI were used as outcome measures.Results Repeated measures of ANOVA showed an increase in flexion and extension in both the groups. Decrease in NDI was also noted with F value of 132.888 for duration p0.000 but between the groups NDI did not show significant difference with F value of 0.011NS p0.918NS. The Chi square value was 55.491 p-value0.001 indicating that duration has an important role in decreasing pain. To compare the effectiveness of techniques in both the groups Mann Whitney U test was used and the U value of 40.5 p0.002 obtained indicate a significant reduction in pain in the manipulation group.Conclusion In both the groups considerable improvements in the outcome measures from baseline to post treatment were observed but the results were not statistically significant in case of ROM and NDI. In terms of pain manipulation group showed significant reduction in pain compared to mobilization group.To conclude Maitland thrust manipulation is more effective than non-thrust manipulation in subjects with mechanical neck pain.nbsp

Published: April 2023

The article emphasizes various aspects of the study of credit-module learning, highlights the relevance of the study and analysis of previously known but little explored facts, conclusions, recommendations contained in domestic rules and regulations of higher pedagogical education, psychological and pedagogical literature of the selected period. The purpose of the article is determination of the features of the introduction of credit-module training in the practice of domestic institutions of higher pedagogical education in the 90s of the XX century – the first decade of the XXI century. It was noted that the introduction of the credit-module system in teachers’ education took place against the background of the formation of a new educational policy of independent Ukraine, which was enshrined in certain regulations and aimed at destroying the old paradigm of education founded during totalitarianism of the old paradigm of education, overcoming the contradictions in the system of higher pedagogical education. The development of the theory of credit-module learning was carried out under the influence of various pedagogical concepts (personality-oriented, developmental, personalization of learning, educational content, etc.). On the basis of the analysis of scientific literature, we show the views of scientists on the nature, features, and benefits of credit-module training, its purpose, principles of implementation, and conditions of effective use. We emphasize the gradual introduction of credit-module training and a rating system of control of students' knowledge in Pedagogical Universities, normative documents, goals and selected basic institutions for the pedagogical experiment. On the example of the M.P. Drahomanov National Pedagogical University and G.S. Skovoroda Kharkiv National Pedagogical University, we analyze the measures which were adopted by Pedagogical Universities to support the organization of the educational process on a new basis. We highlight the directions and give the examples of using individually-differentiated personality-oriented form of organization outside the classroom individual work of a student. Besides, it was given the results of researches of scientists of positive consequences and unresolved problems of introduction of credit-module training in practice of institutions of higher pedagogical education, shortcomings of rating control of knowledge.
Globalization or deglobalization of education? Lessons of the COVID times
Authors: Nalyvaiko Oleksii
Published: April 2023

The process of all-pervasive integration, which binds the world socio-economic activity in recent years, has significantly slowed down due to a number of reasons. These include the aggravation of contradictions within the most developed centers of the economy and culture, constant economic upheavals in the form of economic crises as well as the Covid-19 pandemic. These reasons together have a significant impact on education around the world and lead to a deterioration in its quality through the loss of global cooperation in the exchange of personnel, ideas and results in scientific and educational fields. The purpose of the study is to designate the influence of deglobalization factors on the educational process in the context of crisis phenomena. The paper presents arguments in favor of strengthening deglobalization processes in most countries of the world. If we talk about learning, these processes are caused, first of all, by the deterioration of the economic situation of educational systems in the context of the Covid-19 pandemic and the global turbulence that now leads to deterioration in the situation of all participants in the educational process, both in economic terms and in terms of opportunities to realize their educational and scientific potential. It is important to note that for the Ukrainian education system, the introduction of quarantine restrictions and general de-globalization processes led to a colossal outflow of foreign students and the loss of the remnants of the potential that the country's leading universities had. It can already be said now that the introduction of forced distance learning has led to deterioration in the quality of education and the devaluation of the national education system. The presence of digital tools and training tools still retains opportunities for cooperation in the face of quarantine and economic restrictions, but this resource also has limitations and requires constant improvement for effective interaction.

Salah satu penyebab utama meningkatnya angka kecelakaan di Indonesia adalah kelelahan dan kantuk yang menempatkan Indonesia di antara negara lain dengan tingkat kecelakaan tertinggi. Adapun elemen yang secara signifikan memengaruhi kelelahan dan kantuk adalah faktor individu yaitu chronotype dan Body Mass Index (BMI). Kelelahan dan kantuk dapat diukur menggunakan indikator sinyal EEG yang mana telah terdapat dalam beberapa studi terkait yang berfokus pada fluktuasi sinyal EEG dalam kondisi operasi tertentu, tetapi hanya sedikit yang meneliti efek chronotype dan BMI pada rasa kantuk. Penelitian ini bertujuan untuk menyelidiki hubungan antara kronotipe dan BMI dengan kelelahan. Kuesioner KSS dan indikator sinyal EEG digunakan untuk mengevaluasi kantuk. Temuan penelitian menunjukkan bahwa sinyal beta dan BMI pengemudi memiliki hubungan yang negatif, yaitu pengemudi dengan BMI tinggi lebih cenderung mengantuk daripada pengemudi dengan BMI rendah. Pada chronotype, tipe moderate morning menunjukkan peningkatan power Alpha dan Theta dibandingkan tipe lainnya, yang disebabkan oleh ritme sirkadian.

Published: April 2023

Purpose: This study aimed to evaluate a hospital-provided hybrid parental support program designed to help parents implement routine interventions for their toddlers under 34 months, with or at risk of autism spectrum disorder (ASD).Methods: An experimental group including 15 pairs of toddlers and their parents received eight weekly sessions, while a control group including nine pairs received no sessions. Toddlers’ joint attention, autism-related behaviors, and adaptive behaviors, as well as parenting stress and parenting efficacy, were compared between baseline and 8 weeks later. Results: The toddlers in the experimental group showed significant improvement in their joint attention scores on the Early Social Communication Scales (P<0.01) and the Korean-Childhood Autism Rating Scale scores (P<0.01). However, statistically significant differences were not found in the adaptive behavior composite scores of the Korean Vineland Adaptive Behavior Scales-II and total behavior problem scores of the Korean version of the Child Behavior Checklist. Parenting efficacy in the experimental group showed significant improvement (P<0.05). Parenting stress increased in the experimental group, but the difference was not significant. Additionally, parents showed a statistically significant between-group difference in parenting efficacy (P<0.05). Conclusion: A hospital-provided hybrid program affected the development of toddlers with ASD and parents’ implementation of interventions. It is significant that an online platform was used to provide individualized support for families to continue practicing the interventions and that the effectiveness of this program was demonstrated. This intervention can be considered as an efficient and sustainable alternative system to support toddlers with ASD and their families.

Authors: Kamineni Meghana , Engø-Monsen Kenth , Midtbø Jørgen E , Forland Frode , de Blasio Birgitte Freiesleben , Frigessi Arnoldo , Engebretsen Solveig
Published: April 2023

Background

Given the societal, economic and health costs of COVID-19 non-pharmaceutical interventions (NPI), it is important to assess their effects. Human mobility serves as a surrogate measure for human contacts and compliance with NPI. In Nordic countries, NPI have mostly been advised and sometimes made mandatory. It is unclear if making NPI mandatory further reduced mobility.

Aim

We investigated the effect of non-compulsory and follow-up mandatory measures in major cities and rural regions on human mobility in Norway. We identified NPI categories that most affected mobility.

Methods

We used mobile phone mobility data from the largest Norwegian operator. We analysed non-compulsory and mandatory measures with before–after and synthetic difference-in-differences approaches. By regression, we investigated the impact of different NPI on mobility.

Results

Nationally and in less populated regions, time travelled, but not distance, decreased after follow-up mandatory measures. In urban areas, however, distance decreased after follow-up mandates, and the reduction exceeded the decrease after initial non-compulsory measures. Stricter metre rules, gyms reopening, and restaurants and shops reopening were significantly associated with changes in mobility.

Conclusion

Overall, distance travelled from home decreased after non-compulsory measures, and in urban areas, distance further decreased after follow-up mandates. Time travelled reduced more after mandates than after non-compulsory measures for all regions and interventions. Stricter distancing and reopening of gyms, restaurants and shops were associated with changes in mobility.

Published: April 2023

The paper presents the results of a study of iron metabolism in full-term infants conceived naturally and using in vitro fertilization (IVF) technology. The data obtained allowed us to conclude that there were no statistically significant differences in the studied indicators in the groups and did not reveal the effect of IVF technology on the iron metabolism of full-term newborns. The purpose of the study. To study and compare the data of iron metabolism - hemoglobin, serum iron, serum transferrin recep-tor (sTfR), ferritin, ferritin index (sTfR/logFer), transferrin saturation, zinc protoporphyrin/ heme ratio in full-term infants conceived using IVF technology and children born by natural conception. Materi-als and methods. Clinical, biochemical and statistical methods were used in the work. The indicators of hemogram and ferrokinetics were determined in 20 full-term children conceived by observation, and in 18 children born using the technology of in vitro fertilization. Research results. In full-term children born as a result of IVF procedure, the level of Hb it was 17,03 ± 0,82 g/dl. The level of serum iron was comparable in the study groups (in full–term children conceived naturally, it is 26,09 ± 0,68 μmol/l, in children conceived by IVF – 25,24 ± 0,5 μmol/l). Studies of the ferritin level in full–term children conceived in the traditional way showed values of 175,73 ± 11,63 μg/l, in children after IVF procedure – 177,04 ± 11,21 μg/l. When calculating the ferritin index (sTfR / log10 Ferritin), data were obtained - in full-term children, the ferritin index is 3,72 ± 0,28 and 4,03 ± 0,36 mg/l depending on the method of conception, the differences are not statistically significant. In full-term children conceived naturally, the TS level was determined to be 61,18 ± 4,11 %, and in full-term children born as a result of traditional conception – 61,77 ± 5,3 %. Conclusion. The study allowed us to conclude that there is no statistically significant effect of the IVF method on iron metabolism and ferrokinetic factors in full-term newborns conceived by this method.

Com o surgimento de doenças de caráter zoonóticos, desde o fim da segunda guerra, a implementação do médico veterinário na área da saúde se tornou necessária. Entretanto, no Brasil, somente em 1997 o Ministério Da Saúde reconhece o médico veterinário como atuante da área da saúde. A partir desse momento, com a ampliação das equipes de Atenção Primária (APS) surge em 2008 os Núcleos de Apoio à Saúde Familiar (NASF) para ampliar o atendimento as comunidades, intervindo tantos em termos clínicos e sanitários. A inserção do médico veterinário no NASF aconteceu apenas em 2011, entretanto ainda são poucas equipes que integram o profissional em sua multiprofissionalidade.

INFLUENCE OF AL2O3 NANO ADDITIVES ON THE VISCOSITY AND THERMAL CONDUCTIVITY OF DOUBLE DISTILLED WATER
Authors: Sami Abed Samir , Sediqhi Mehdi , Diwan Abbas
Published: April 2023

The nano fluid consist of Al2O3 nanoparticles was dissolved by double distilled water (DDW) in three concentrations, 0.5% wt, 1%wt, and 1.5%wt of nanomaterials.  The effect of adding nano materials on the viscosity and thermal conductivity was calculated experimentally at room temperature. Some mathematical models were used to calculate the viscosity and the thermal conductivity and compare it with the experimental work. The results showed that viscosity and thermal conductivity increased with increasing concentration of Al2O3 nanoparticles, and there is a great convergence between the theoretical and measured viscosity and thermal conductivity. The SEM images showed that there is homogeneity in the distribution of the nano fluid at 1%wt., and some agglomerations were detected at a concentration 1.5%.  The EDS spectrum showed that the percentage of aluminum increased gradually with increasing the Al2O3 concentration. The X-Ray diffraction indicated slight increase in the intensity of diffraction with increasing the Al2O3 concentration.
Exploring the centrality of women in indigenous peacemaking among the Mende of Sierra Leone
Authors: Hindowa Batilo Momoh
Published: April 2023

This paper examines, among others, the central role women play in traditional peacemaking and conflict management among the Mende of Sierra Leone. The study argues that Mende women have a historically proven record, an enduring courage and a demonstrated pedigree to intercede to end hostility and restore normalcy to communities embroiled in disputes/conflicts. It further explores the key role these women play in simmering down highly volatile situations and preventing conflicts from occurring. While the study concedes that male chauvinism and some core cultural traditions continue to disempower women and relegate them to playing a subordinate role in some traditional societies, there is also evidence that women play a central role in influencing decisions that help build the culture of community and the architecture of peace. Women continue to hold strategic decision-making positions (as Mammy Queens, Soweis, Chiefs, heads of women groups etc.) that animate social reordering, political transformation and peacemaking in local communities. The paper concludes that women, by their nature as mothers, educators, counsellors, mentors, leaders etc., have the history of reconciling conflicting parties and in helping bring about amiability to communities encumbered by conflicts.

Neste trabalho, realizamos uma breve reflexão panorâmica acerca da teoria da diáspora e seuconceito, tomando como base o contexto da históriada literatura ocidental. Nossa trajetória divide-se emduas partes. Em primeiro lugar, abordamos a historiografia da diáspora, lançando um olhar sobre o desenvolvimento do conceito e suas diferentes implicações teóricas com o passar do tempo. Assim, revisitamos os possíveis sentidos do termo diáspora, metafórica e literalmente, desde a etimologia até as discussões atuais traçadas por estudiosos sobre o tema. Em segundo lugar, discutimos a noção de literatura diaspórica no mundo ocidental contemporâneo como fruto da produção de sujeitos diaspóricos, realçando as características principais desse sujeito que serão responsáveis, mais tarde, por uma consciência diaspórica crítica e autorreflexiva.

Thermal comfort assessment in the modern passenger car under actual operational conditions
Authors: Dębska Luiza , Krawczyk Natalia
Published: April 2023

People’s ever-increasing needs encourage designers of various vehicles to search for solutions that will provide the most comfortable internal environment conditions. Currently, partly due to the COVID-19 threat, many people use their individual cars to travel to work, college, shops, trips, and holidays. Proper internal air parameters that need to be maintained in vehicles are critical in the summer. The article discusses the thermal comfort of four passengers of a modern car produced in 2017 to verify if contemporary production technology can successfully meet the thermal needs of people under actual conditions in the Polish climate. For this purpose, five temperature values were tested: 20°C, 22°C, 24°C, 26°C, and 28°C for the car located in the shade and sun. In addition, the Testo 400 meter was used to control and measure the internal parameters, and questionnaires were used to find out about the thermal impressions of the respondents. The research was carried out in July when the air temperature in Poland was high.

Published: April 2023

This manuscript aims to familiarise readers with the development of a device for the construction of a mobile disinfection chamber for small communication devices and small objects. The conceptual design and the material of the new device play essential roles in the design process of a new device. The manuscript presents concepts based primarily on previous experience and different perspectives. The concept design is created in the 3D modelling program CREO Parametric 8.0. A multi-criteria team evaluation determined the most suitable version of the idea. For dimensioning and shape adaptation of the device was used EinScan SP device (3D scanning method). The article's aim was also to establish a suitable way of producing a prototype using tribological research in available production methods and materials within rapid prototyping. Using the ALICONA Infinite Focus G5 device, experimentally investigated the parameters characterising the surface of the parts. The end of the manuscript focused on the mechanical structure and subjecting them to FEM analysis in the program ANSYS Workbench. The design of the concept disinfection device was also for extreme cases of use. Within this issue was optimising shapes, wall thicknesses, reinforcement design and other necessary modifications using the FEM analysis. From the results, the most suitable material to produce a more significant number of parts may not be the most suitable material to create prototype devices. Tools such as 3D scanning, rapid prototyping, and FEM analysis can "significantly" help reduce mistakes before testing the device.

The manuscript focuses on the subject of environmental solutions for maritime ships. With the increasing volume of cargo transported by sea, it is crucial to minimise its environmental impact. The International Maritime Organization (IMO) has introduced new regulations in recent years to limit environmental damage. IMO’s initial strategy for reducing GHG emissions from ships aims to reduce GHG emissions from vessels by 50% by 2050 and CO2 emissions by 70% compared to 2008 (Resolution MEPC.304 (72), 2018). This has prompted ship owners to seek solutions to reduce fossil fuel consumption. The study aims to determine the feasibility of using eco-friendly solutions in maritime shipping to meet the challenges and needs of sustainable maritime fleet. Own contribution includes expert findings, which evaluate individual solutions and their potential uses in global maritime fleet. The publication also highlights the current usage of eco-friendly solutions on ships as well as crew and ship owner attitudes towards their future use and presents conceptual solutions. It should be noted that the subject-matter addressed in this paper is topical and very important in view of the limitations being introduced in respect of environmental standards.

The paper talks about the facts that were established in the research of the origin of fruits and vegetables in the markets of Novi Sad. The results of the research are presented using graphic and cartographic methods. Observed illogicalities are clarified in communication with consumers and sellers. The obtained results were compared with foreign works. One of the goals of the work was to determine the extent of suburban agriculture, which should be the most competitive with others further away from the city. Economic factors have a decisive influence from where the city will be supplied with fruits and vegetables.

The article discusses the recent significant increase in interest in the practical ap­plication of business software (SW). Today, it is clear to everyone that management prospects are in the field of information technology. There are many software products on the market that are used for business software, management, financial and business consulting, enterprise or holding management, project management, business cycle optimization and document cycle automation.The article discusses the selection of software tools for automating business planning processes, as there has been a growing interest in the practical application of business software. Business software can be classified into several categories such as enterprise management systems, accounting software, document management systems, etc. The article emphasizes that the choice of a specific software product is related to its functional features and the environment in which it is used. The article identifies three levels of management, and for each level, different requirements for software are identified. The article divides project management software into two groups, entry-level programs, and professional systems, and discusses their functionalities and costs. The article concludes that there is an intermediate position for project management software, which integrates features of the first two groups. Furthermore, it is emphasized that domestic developments in project management software are preferred by many users due to their availability and low cost. The article suggests that with project management packages, financial managers can obtain detailed financial plans, financing schemes, and business evaluations for decision making. The article concludes by outlining key factors that must be taken into account when selecting project management software, such as complexity, updating options, scalability, user interface, resources, coding, calculated fields, risk analysis, and task distribution. The article emphasizes the importance of business-planning-analytics packages in helping managers build effective financial models by dynamically simulating time-varying factors.
Tuning of PID Controllers for Quadcopter System using Cultural Exchange Imperialist Competitive Algorithm
Authors: Abbas Nizar Hadi , Sami Ahmed Ramz
Published: April 2023

Quadrotors are coming up as an attractive platform for unmanned aerial vehicle (UAV) research, due to the simplicity of their structure and maintenance, their ability to hover, and their vertical take-off and landing (VTOL) capability. With the vast advancements in small-size sensors, actuators, and processors, researchers are now focusing on developing mini UAV’s to be used in both research and commercial applications. This work presents a detailed mathematical nonlinear dynamic model of the quadrotor which is formulated using the Newton-Euler method. Although the quadrotor is a 6 DOF under-actuated system, the derived rotational subsystem is fully actuated, while the translational subsystem is under-actuated. The derivation of the mathematical model was followed by the development of the controller to control the altitude, attitude, heading and position of the quadrotor in space, which is, based on the linear Proportional-Derivative- Integral (PID) controller; thus, a simplified version of the model is obtained. The gains of the controllers will be tuned using optimization techniques to improve the system's dynamic response. The standard Imperialist Competitive Algorithm (ICA) was applied to tune the PID parameters and then it was compared to Cultural Exchange Imperialist Competitive algorithm (CEICA) tuning, and the results show improvement in the proposed algorithm. The objective function results were enhanced by (23.91%) in the CEICA compared with ICA.

Published: April 2023

Compaction curves are widely used in civil engineering especially for road constructions, embankments, etc. Obtaining the precise amount of Optimum Moisture Content (OMC) that gives the Maximum Dry Unit weight gdmax. is very important, where the desired soil strength can be achieved in addition to economic aspects.

In this paper, three peak functions were used to obtain the OMC and gdmax. through curve fitting for the values obtained from Standard Proctor Test. Another surface fitting was also used to model the Ohio’s compaction curves that represent the very large variation of compacted soil types.

The results showed very good correlation between the values obtained from some published sample tests and the values obtained from curve fitting for both cases of the single curve and multiple Ohio’s curves.

The easiness of obtaining OMC and gdmax. From the results of curve fitting encourage users to utilize this procedure, in addition to its accuracy.

Published: April 2023

El movimiento de los organismos a través del paisaje resulta de la interacción entre las propiedades estructurales y características que determinan su capacidad de movimiento, generando patrones de conectividad particulares para cada ambiente y especie. El norte de Neuquén presenta una alta heterogeneidad espacio-temporal en variables climáticas y ambientales. El objetivo de este trabajo es modelar la conectividad potencial entre áreas de veranada e invernada, y evaluar los factores que influyeron en el uso del espacio de las poblaciones humanas prehistóricas en la región. Con este fin generamos expectativas a partir del modelado de las áreas potenciales de circulación en la actualidad y luego evaluamos las expectativas generadas con la distribución espacial de sitios arqueológicos. Esta aproximación actualística permitió generar modelos de circulación que mostraron la existencia de dos corredores principales con dirección noroeste-sudeste. Los resultados obtenidos también indican que el modelo generado muestra un buen ajuste a la ubicación de diferentes tipos de sitios arqueológicos. La aproximación seguida en este trabajo mostró que las variables topográficas y ambientales resultaron útiles para generar expectativas sólidas acerca de las áreas en las que podrían haberse emplazado las principales rutas de movilidad de la región durante el Holoceno tardío.
