Kolokacija i zajedničko korišćenje u pravu elektronskih komunikacija - upravnopravni aspekti -
Authors: Đurić Vladimir
Published: May 2023

Co-location and sharing of network elements in the field of electronic communications means that one or more operators use the same resources and means (usually infrastructure and related equipment) in order to provide services to end users. This paper specifically analyzes the solution introduced into the legal system of the Republic of Serbia by the Law on Electronic Communications 2010. The conclusion is that legal solutions on collocation and sharing of network elements in the legal system of the Republic of Serbia are not fully harmonized with EU law and don’t have systemic quality, especially in the administrative law sense.
Istorija prenosa prava svojine po osnovu ugovora o kupoprodaji

The Roman contract of sale (emptio venditio) and the concept of consensual contracts were adopted by all European and world legislation created on the ruins of the Roman Empire or under the indirect influence of this civilization. As a bilateral, equally binding bonae fidei contract, it gave rise to obligations for both parties, while not transferring either the possession or the right of ownership from the seller to the buyer. In order to transfer ownership, it was required to add an act consisting of mancipatio, for res mancipi, or traditio, for res nec mancipi. In the paper, the author points to the historical development of the transfer of property rights based on the contract of sale, both in Roman law and in modern European codifications, to its dynamic development and the differences in European legal systems. In particular, he examines the question of whether traditio is an act that enables someone to acquire factual power over things or a legal transaction. The results indicate the following. The dilemma about the legal nature of tradition originates from Gaius. Based on the legal texts, it can be concluded that classical jurists understood traditio both as a way of acquisition and as a consent of will, having in mind that there is a conflict whether it is a one-sided or two-sided legal transaction; according to Paulus, it is a unilateral legal transaction and according to Iavolenus, bilateral. Furthermore, for Ulpianus, the traditio is a contract, independent of the basis on which the traditio is carried out. Iulianus opinion, although it is questionable as to how original it is, is revolutionary – it is an independent legal transaction based on the agreement of two parties, regardless of the cause; there is no evidence that the sighting was accepted in Roman law and Romanists suggest that it is an interpolation. On the other hand, the Prussian Landrecht (ALR) and the French Civil Code (CC) foresee a departure from the Roman models – the transfer of property rights occurs by agreement of the will of the parties; the concept originated from members of the natural law school Hugo Grotius, Christian Wolff and Jean Barberac. A contrario, the German Code (BGB) defines the traditio as an abstract act by which the property right was transferred, regardless of the nullity or validity of the initial contract, or even whether it exists. The Austrian (ABGB), but also the Serbian (SGZ) and Swiss (ZBG) Civil Codes remain true to the classic Roman concept that titulus and modus are required for the transfer of ownership based on a contract of sale.

Contamination Control During Sample Preparation for Trace Element Analysis of Electronic Cigarette Aerosol with Inductively Coupled Plasma-Mass Spectrometry, Part 1
Authors: Pappas R. Steven , Gray Naudia
Published: May 2023

In this two-part article, the authors take a look at the major factors affecting background contamination in inductively coupled plasma-mass spectrometry (ICP-MS), particularly when measuring ultratrace elements in specialty applications such as aerosol matrices from electronic cigarettes and electronic nicotine delivery systems (ENDS). In order to obtain meaningful data, the analyst must understand and address the magnitude and variability of environmental contamination by ubiquitous trace metals during the sample preparation procedure. The impact of these contaminants on the procedural blank and the associated impact on the accuracy and precision of sample results can unfortunately lead to false positive results.

This article proposes a method for the determination of thiosulfate by decoloring spectrophotometry with methylene blue as an oxidant. Methylene blue has redox properties. Its oxidized form is blue, and its reduced form is colorless. Thiosulfate is a medium-strength reducing agent. In an acidic medium, the two can undergo redox reactions to reduce methylene blue and cause the solution to exhibit a fading reaction within a certain range, and the degree of fading is proportional to the amount of thiosulfate added. This method measures the change in absorbance (AU) at a fixed wavelength of 664 nm, and ΔAU has a linear relationship with the content of thiosulfate. The linear range is 0–0.3 mmol/L. From this curve, the content of thiosulfate in the desulfurization solution can be accurately measured. This method is not interfered with by other secondary salts in the desulfurization solution during the thiosulfate determination process, and has high sensitivity. The color change can be observed by the naked eye to judge whether there is thiosulfate in the solution. This method is simple to perform and is an improved method for the determination of thiosulfate in a desulfurization solution.

Aim: This study was conducted to evaluate body weight performance, egg production and egg quality traits of Lohmann chicken genotype in Wachemo University.

Methodology: For the experiment, the Lohmann layer chicken in the University farm was used and SAS ver 9.4 was used to analyze the data. Body weight and egg production progress were evaluated at different times. A total of 200 eggs (100 at the end of 1st month and 100 at the end of 3rd month of egg lay) were brought to Hawassa University poultry farm laboratory to assess the egg quality traits. For the data analysis, SAS (Ver. 9.4) was used.

Results: The Lohmann chickens weighed 0.93kg at their entry to the university poultry farm and increased in to 1.34kg at end of first month of entry. In the farm, about 34.4%, 42.5% and 58.6% of the hens have laid egg until the end of first, second and third months of egg lay respectively; this indicates that the increasing trend of egg production of Lohmann chickens as age increase. Egg laying age difference has a significant effect (p<0.05) on egg weight, egg length, egg width, shell thickness, egg surface area and shell ratio. There was a significant difference in yolk weight, yolk diameter, albumen ratio and yolk index for the eggs collected from the Lohmann chickens at different age. Egg weight has the strong and positive correlation with egg length (78.6%), egg width (84.7%) and egg surface area (99.8%). Albumen weight is more correlated with albumen ration (64.2%) positively and yolk albumen ration (65.6%) negatively.

Conclusion: Poultry production could be influenced by many factors. Among the factors, age was evaluated in the current study; as age increased, the growth performance, egg production and egg quality traits improved.

Authors:   Le Quy Don Technical University, Nguyen Manh Tien
Published: May 2023

Superplasticity is the ability of an alloy to be permanently stretched to very high elongation within a limited range of conditions (grain size d, deformation temperature T, strain rate  ). In particular, the fine stable grain size has a significant influence on the appearance of the superplastic microstructure deformation. The average size of the grain must be less than 15 μm and kept stable during the superplastic forming process. Thus, this paper determines the thermomechanical regime and prepares microstructure for superplastic deformation of the AA7075 aluminum alloy. The results obtained microstructural features with fine stable and grain size (~13 μm).

Authors:   Le Quy Don Technical University, Nguyen Dinh Ngoc ,   Posts and Telecommunications Institute of Technology
Published: May 2023

With the increasing wireless data traffic and data rate demands, milimeter-wave band corresponding to the frequency range 30-300 GHz has much attention of the researchers. Using multiple antennas at the transmitter and the receiver with beamforming helps overcome high transmission loss. Therefore, millimeter-wave Multiple-Input Multiple-Output (mmWave MIMO) is a key technology for the next generation wireless communication system. However, due to hardware constrains when operating in the high frequency range, the performance of a mmWave MIMO system will decrease. In this paper, we analysis system performance of a hybrid beamforming mmWave MIMO system with non-ideal hardware (phase noise and quantization noise).
EXTENDING THE DEPTH OF THE FIELD FOR OPTICAL SYSTEM VIA A NEW SINUSOIDAL PHASE MASK
Authors:   Le Quy Don Technical University, Le Van Nhu
Published: May 2023

In this paper, we propose a new sinusoidal phase mask to extend the depth of focus in optical imaging system. Imaging performance of the proposed phase mask is compared with cubic phase mask, logarithmic phase mask, and sinusoidal phase mask by using the evaluated functions such as the modulation transfer function (MTF), the area of the MTF, the Hilbert space angle of the MTF and simulation image. The results indicate that the proposed phase mask can be used to obtain the MTF more invariant over a wide range of defocus and reduce strongly the effect of image artifacts on the restored images.
THE IMPACTS OF HARDWARE IMPAIRMENTS AND RESIDUAL SELF-INTERFERENCE ON THE ERGODIC CAPACITY OF FULL-DUPLEX AMPLIFY-AND-FORWARD RELAY NETWORKS
Authors:   Le Quy Don Technical University, Nguyen Ba Cao
Published: May 2023

In this paper, we analyse the ergodic capacity of the one-way and two-way full-duplex (FD) amplify-and-forward relay systems under impact of hardware impairments (HI) in the case of imperfect self-interference cancellation. The ergodic expressions of these systems when the relay node uses fixed and variable gains are derived. Numerical results demonstrate that, the ergodic capacity soon becomes saturated at high transmit power due to the residual self-interference (RSI) of the FD mode. However, under the impact of HI and RSI, the FD systems achieve higher ergodic capacity than the HD ones. Simulation results are provided to validate the analysis.

Published: May 2023

The paper proposes a new method to improve the performance of the target detection in the sea clutter using the standard deviation of degree of polarization DoP. The performance of the detection using parameter DoP and the standard deviation of DoP were examined with different types of targets in different models of clutter such as Rayleigh, Weibull and Laplace; and a special case of parameter DoP of target which is the same as that of the clutter was investigated as well. The results show that the effectiveness of the detection using the standard deviation of DoP is increased significantly and better than using only the parameter DoP.

Published: May 2023

El presente artículo pretende mostrar los efectos jurídicos en el sector agrícola del TLC suscrito entre Colombia y Estados Unidos. Para poder dar razón de la eficacia o ineficacia del mismo, la investigación detalla el antes, durante y después de las negociaciones del tratado, lo que permitirá en una segunda parte detallar como el sector agrícola se ve afectado con su aplicación. Teniendo en cuenta el método de investigación planteado para el desarrollo de este escrito, como primer resultado cuantitativo es válido decir que los aspectos políticos y de negociación manifestado por los líderes políticos y sus mesas de negociación del momento, tenían una visión integradora del intercambio de productos, dando prioridad al sector agrícola, visión que buscaba claramente un mayor flujo y variedad de mercados para que fuera el consumidor quien eligiera partiendo de aspectos como la calidad y precio, algo que resulta atractivo para todos  los sectores, sin embargo, al momento de expedir el documento final que jurídicamente regula dicho intercambio comercial, se puede evidenciar, como desde la parte de la producción hasta entrega final de una mercancía de origen agrícola, no existe efectivamente una paridad, pues los gobiernos influyen y apoyan de manera distinta los sectores productivos de su país, es allí, donde se refleja claramente una desventaja del productor Colombiano y su forma de competir con los bienes de origen estadounidense, es allí como segundo resultado, desde los analítico, se concluye que si bien es cierto la competencia y la apertura de nuevos mercados a través de los TLC es buena, deben existir mayores apoyos económicos, en capacitación y otros aspectos, que permitan a ese agricultor nacional competir de manera efectiva con los productos importados y generar una verdadera exportación de calidad competitiva en el mercado extranjero.

Protección de estado ecuatoriano a las personas con discapacidad en materia de inserción laboral
Authors: Carrasco Lara Gabriela Paola
Published: May 2023

La discapacidad se refiere a una limitación física, mental o sensorial que afecta la capacidad de una persona para realizar ciertas actividades cotidianas que se consideran normales para la mayoría de las personas. Las discapacidades pueden ser congénitas (presentes desde el nacimiento) o adquiridas a lo largo de la vida, y pueden ser temporales o permanentes. Es importante tener en cuenta que la discapacidad no define a una persona y que todas las personas tienen habilidades y talentos únicos, independientemente de sus limitaciones. La inclusión y la accesibilidad son fundamentales para garantizar que todas las personas, incluidas aquellas con discapacidades, puedan participar plenamente en la sociedad y tener las mismas oportunidades que los demás. (YISIMIA, 2022). Las personas con discapacidad enfrentan un conjunto único de desafíos cuando se trata de encontrar y mantener un empleo. A pesar de las leyes que protegen sus derechos, siguen siendo discriminados en el lugar de trabajo. Esto es especialmente cierto para las mujeres discapacitadas, a quienes a menudo se las pasa por alto y no se les brindan las mismas oportunidades que a sus homólogos masculinos. La inserción laboral de las personas con discapacidad es un tema importante que debe ser abordado. Al brindar más oportunidades de colocación laboral específicamente para personas discapacitadas, podemos ayudarlos a obtener acceso a un empleo significativo y desarrollar carreras exitosas. Además, lo empleadores pueden beneficiarse de las diversas perspectivas y conjuntos de habilidades que estas personas aportan (MARIA, 2021)

Guru Ghasidas Ji, The pioneer of Social, Religious and Economic Movement in Chhattisgarh
Authors: Ganesh Koshle  , Ghanshyam Dubey
Published: May 2023

At that time in Chhattisgarh, the life of innumerable Dalit, exploited, oppressed people was very miserable. Untouchability, high-low discrimination was prevailing in the society. The tradition of human sacrifice and animal sacrifice was prevalent in the temples in the name of religion. Maths and temples had become centers of incest, exploitation of women was seen in temples, people were being cheated in the name of superstitions like Tantra-Mantra, Tonhi, Baiga, Pangha etc.

The form of religious practice had become very distorted, people were consuming meat and alcohol in the guise of righteousness. The people here were very troubled by the loot and terror of the kings, feudatories, pindaris, subedars, the rent and revenue collection had broken their back. At such a time Saint Shiromani Guru Ghasidas ji was born on the land of Chhattisgarh in village Giroudpur. He established 'Satnam Panth' and he rejected the dominance of Brahminism and opposed the caste system dividing into varnas.

Gave the message of 'man-man is equal' against casteism, untouchability, caste disparities prevailing in the society. Every person in the society has a socially equal status. Guru Ghasidas prohibited idol worship. He made a significant contribution in generating a new thinking and idea in the society.
Modern Sanskrit Children's Literature
Authors: Hemraj Saini
Published: May 2023

In the modern poetry world, the use of the word 'literature' by the poets is considered in the sense of poetry. In the past, the noun 'poetry' actually used to express poet-action - kaveh karma kavyam.

In the modern context, the word 'literature' used in place of poetry has been used in three senses on the basis of evidence of practical experiments-

Firstly - on the evidence of 'Sahityapathonidhimanthannottham Kavyamritam Rakshat he Kavindra': The meaning of the word literature is very wide, that is, the word literature is also used in the meaning of all written oral literature.

Secondly - 'Sahitye Sukumarvastuni Dharvannayagrahagranthile', on the evidence of this statement of Shri Harsha, the word literature is used in the sense of a special 'poetry', a part of literature.

Thirdly - In 'Sahityavidyashramvarjiteshu.....' the word literature has been used in the combined sense of poetry and poetry.

In modern life, the word literature or poetry expresses the same feeling in Sanskrit... 'Sahiten Bhavah Sahityam'. In fact, 'poetry' or 'literature' is defined in different contexts from ancient poets to modern poets. In the context of literature, Acharya Bhamah of Kavyashastra has the opinion that- “Shabdharthau sahitau kavyam.”1

That is, the meaning of the meaning is poetry. The association of semantics is visible in practical sentences and sentences based on classical or scientific thinking. But the association of poetry is different from this. In fact, the feeling of Bhamaha word meaning which is called literature is an excellent quality of co-feeling. That association should be such that on the one hand the reader receives derived opinion in various purusharths, as well as the hearty child, the young man i.e. the poetry connoisseur gets joy and happiness.

This problem-solving solution may help for sustainable development. This paper explains present technological advancement, its importance, and its application. This chapter concludes that there are numerous advantages in implementing the technical aspect of education but at the same time need skills to solve the technological issue.
Intratumoural Heterogeneity as a Major Challenge for Cancer Modelling and Successful Treatment
Authors:   Randall Division of Cell and Molecular Biophysics, King's College, London, UK, Pruller Johanna
Published: May 2023

Cancer heterogeneity refers to the fact that cancer cells are characterised by different genomic/transcriptomic/proteomic compositions, which often confer behavioural properties, such as enhanced drug resistance, survival and propensity to form metastasis. Modern methodology, such as single-cell barcoding, now allows a deeper look into this mechanic, and therefore a possibility to derive more efficient, new treatments. However, cell culture approaches are commonly used to evaluate those novel approaches, and the ability to faithfully model cancer heterogeneity is still in its infancy.
The utility of a peer review application in interdisciplinary teamwork arrangements
Authors: Johnson Coralie , Macleod Miles , Visscher Klaasjan
Published: May 2023

Project and challenge-based learning typically require students to navigate personal and professional relationships within a team, in order to collaboratively solve authentic problems. These collaborations are often interdisciplinary in nature – an arrangement that adds increased complexity to the team’s functioning. This is due to distinctions in approaches, epistemologies, ethos or jargon. The ability to provide (and receive) appropriate and constructive feedback to peers, within the team, is a key skill that can enhance team functioning and ultimately, output. Furthermore, it is a competence that aids in lubricating social and work impediments that may be causing bottlenecks to creativity, or the manifestation of ideas. The aim of this study, set within three different interdisciplinary bachelor modules, is to determine to what extent the use of the ‘Buddycheck’ application for peer review, is appreciated by students and teachers. The application, hosted within the learning management system of the university, allows students to rank their peers’ performance according to teacher-set criteria, as well as through flexible open-format feedback; in order to facilitate opportunities for enhanced communication and expectation alignment. We wish to ascertain to what degree team functioning is enhanced through the scaffolded communication opportunities, by highlighting and creating openings to discuss undesirable behaviours, through the feedback application. Preliminary results appear to favour this mode of feedback facilitation, albeit with certain caveats, detailed later. Since teamwork is universal in tertiary education, these insights may be helpful for educators attempting to further improve the evaluation of the process of their projects or challenges.
Technical and pedagogical challenges for implementing feedback strategies in a virtual learning environment
Authors: Iqbal Asima , Masood Maryam , Schrock Lauren , Makrinov Ninna
Published: May 2023

Pedagogical developments in the virtual learning environment (VLE) are constrained by technical expertise which impacts the design and delivery of online learning, including the implementation of varied feedback strategies. In recognising this dilemma, the paper addresses the question, “What are the technical and pedagogical challenges of implementing feedback strategies in a VLE?” This short paper presents an initial critical, reflexive account on the challenges to embed and manage feedback strategies, including automatic feedback, peer feedback, and tutor-led feedback, on the VLE of a blended module provided to over 1,200 engineering and business students at a UK university. As a result, the authors recognise the importance of upskilling engineering educators to technically innovate their VLEs to enhance student learning and connections through feedback. Further investigations to evaluate the impact of the varied feedback strategies on student learning will occur at a later stage in order to advance this work in progress.
Teachers’ views on collaborating in multi-campus course cluster for engineering students
Authors: Kahrs Magnus , Korpås Guri
Published: May 2023

At a European multi-campus university, parallel study programmes offered at every campus (e.g. engineering studies) and appurtenant courses are coordinated, to ensure similar quality and systematic development. In this paper, we present a case from such a multi-campus course, consisting of a cluster of basic courses in physics and chemistry for first-year engineering students. These courses are coordinated through identical syllabus and assessment practice but are taught locally at each campus. The authors had noted some frustration among the teachers involved in these courses, and were interested to investigate the reasons for this frustration, and ultimately to inform the development of these multi-campus courses. This project emerged from a realisation that literature on multi-campus courses is often associated with distance learning, while in this case, the actual teaching is provided locally. Concepts associated with teacher collaboration, such as collaborative culture versus contrived collegiality, collective versus fragmented collaboration, and depth of collaboration seem like a viable way forward in understanding the dynamics between teachers in a context like this. In this paper, we present early results from this ongoing project, which include interviews of teachers involved in these physics/chemistry courses. Preliminary results from these interviews suggest that the expressed frustrations stem from contrived collegiality. Although the teachers experience sufficient freedom in terms of choosing their own teaching methods, several teachers raise concerns about the lack of common aims for this course cluster, which reduces collaboration to coordination of mere practical tasks.
Reflection in technical higher education: student perceptions
Authors: Eshuis Elise , Mittendorff Kariene , Baarslag Helen
Published: May 2023

The project 'Strengthening reflection in technical higher education programs' is a response to the need for well-trained reflective science and engineering professionals and the subsequent question of teachers about how reflection can be designed and embedded in a meaningful way, especially in technical study programs. Within this project, eight technical education teams from two Dutch universities of applied sciences are working on improving the use of reflection in their curriculum. Among other things, teachers are professionalized in their guidance skills, to improve the guidance of reflective activities of their students. One of the research activities within the project involved a questionnaire to gain insight into: 1) the extent to which engineering students have an inclination and need for selfreflection, 2) the reflection level that engineering students reach according to their own judgement, and 3) how engineering students value (guidance of) current reflection activities in their study program. In the short (concept) paper we will address some main findings of this questionnaire based on data of 843 first- to fourth-year students from eight technical study programs. Amongst others, results indicate - contrary to some other research findings - that engineering students acknowledge the importance of being able to reflect as a future professional. However, they seem relatively less satisfied with currently provided guidance regarding reflection in their study programs. Also, most often employed reflection activities (i.e., reflection reports) are generally perceived least useful. Results give further direction to optimize activities and teacher guidance regarding reflection within higher (technical) education programs.

Published: May 2023

Year after year, a crowd of students from the Universitat Politècnica de València (UPV), a polytechnic university in Valencia (Spain) with over 30,000 students, are encouraged to start their own business projects. Since 1992, IDEAS UPV, the Entrepreneurial service at UPV, has been mentoring entrepreneurs. Up till now, IDEAS UPV has helped in the generation of close to 1000 new businesses with a survival rate of over 60% in five years. In 2012, IDEAS UPV introduced new mentoring and tutorship activities for students by the creation of a business incubator within the university campus. StartUPV is currently a 5-year startup incubation programme and an entrepreneurial ecosystem with more than 300 startups and more than 50 million euros of overall private investment StartUPV programme is divided into three different stages: (i) STAND UP, in which startups define a business model and complete a validation process; (ii) START UP, in which startups achieve a targeted market share and build their company management team; and (iii) SCALE UP, in which startups achieve maturity and scale to other international markets. As university students and their startups face different needs in every step of the programme, different approaches for mentoring and tutorship are applied in every stage. For instance, a startup in the first stage is mentored in business modelling or market segmentation, while a scale up requires a more specific mentorship in dealing with corporates and venture capital. These different approaches are analysed in this work including the main findings of the 10 years of this programme.
Psychological Perspective on Advanced Learners’ Foreign Language-related Emotions across the Four Skills
Authors: Zartashia Kynat Javaid  , Nazish Andleeb  , Samina Rana
Published: May 2023

This research study aims to explore the foreign language-related emotions experienced by advanced learners across the four skills (speaking, listening, reading, and writing). Study was conducted at Government College University Faisalabad, where 50 advanced learners of English as a foreign language participated. The data were collected through mixed-method approach, including questionnaires and interviews. The findings of this study indicate that advanced learners experience a wide range of emotions in foreign language learning, including positive and negative emotions. The most frequently experienced emotions were anxiety, motivation, and enjoyment. Moreover, the findings reveal that the emotions experienced by advanced learners varied across the four skills. For instance, anxiety was most commonly experienced in speaking and writing, while enjoyment was frequently experienced in listening and reading. The results of this study have implications for foreign language educators and suggest that it is essential to consider the emotional dimension of foreign language learning when designing pedagogical practices.

Published: May 2023

During the COVID-19 pandemic, these professions that are at high risk of contracting COVID-19 can trigger ongoing fear, anxiety, stress, fatigue, and emotional trauma that is exacerbated by the stigma of being a carrier of the disease. This can have an impact on nursing services that are not optimal and decrease in performance. The purpose of this study was to determine the relationship of nurses' stigma during the COVID-19 pandemic to the performance of nurses working at Bhayangkara Drs Hospital. Titus Uly and S. K. Lerik Regional General Hospital, Kupang City. This study was designed using a quantitative study with a Cross Sectional design with Chi Square statistical test. A sample of 67 people was taken using Simple Random Sampling.
