Research: “The students are only getting more diverse”: Cultivating Culturally Infused Teaching and Learning with Preservice Teachers in a Professional Learning Community
Authors: McDaniel Dominique Skye , Osborn Matthew
Published: November 2024

Professional Learning Communities (PLCs) have potential as a collaborative model at facilitating culturally relevant/sustainable (CRS) pedagogical practices with preservice teachers. This article presents the results of a study examining the experiences of preservice English educators in a model PLC aimed at fostering understandings of CRS pedagogies with preservice educators. Monthly virtual PLC sessions were conducted over the course of four months, focused on developing an understanding of CRS pedagogies with six preservice educators. Transcripts from PLC sessions and individual interviews were examined through a qualitative case-study analysis to determine themes that emerged from participant experiences. Analysis revealed three themes as central to preservice teachers’ experiences in the model PLC: (1) need for sense of community in the PLC, (2) apprehension regarding perceived administrative response, and (3) enthusiasm for attempting CRS practices in the classroom. PLCs centered on developing CRS practices with preservice educators may aid English teacher education programs in preparing teachers to educate students from culturally and linguistically diverse backgrounds.
Proxy War: An Attempt to Put a Retrospective and Ambiguous Concept into a Specific Framework
Authors: Pektaş Uğur
Published: November 2024

There are two dominant perspectives in the literature regarding the concept of proxy war, which was forgotten in the post-Cold War era but is now regaining popularity. The group led by Karl Deutsch defines proxy war as the intervention of other states in a civil war in a country, and the situation where the civil war in question gains an interstate conflict nature. The other group argues that proxy war was a common form of warfare even before 1945. This study problematizes two perspectives. Accordingly, a new conceptual framework of proxy wars is constructed, aiming to eliminate the conceptual ambiguity caused by these two perspectives.

Hypertension is diagnosed when a person's systolic blood pressure is ≥140 mmHg or diastolic blood pressure (DBP) is ≥90 mmHg after at least two examinations. Hypertension ranks first for 10 cases of non-communicable diseases in the Gembong Health Center Work Area. This study aimed to analyze the decrease in the number of hypertension cases in the Gembong Health Center work area, Balaraja District, Tangerang Regency, Banten Province. The method used is a community diagnosis approach that identifies problems using the Blum Paradigm. Problem priorities are determined using the Delphi non-scoring technique, and the root cause of the problem is determined using a fishbone diagram. Intervention result data were obtained through pre-and post-test questionnaires. Monitoring was carried out with a plan-do-check-action (PDCA) cycle. The evaluation was carried out using a systems approach. Based on the analysis results using a fishbone diagram, the main problem is the lack of public knowledge regarding hypertension. The results of the counselling showed that all participants scored ≥ 70 points on the post-test, and blood pressure measurement screening showed that 9 (45%) participants suffered from hypertension. The community diagnosis approach implemented can increase public knowledge about hypertension.

The objective: to evaluate clinical, laboratory and instrumental signs of generalized mycobacteriosis (MB) in HIV patients.

Subjects and Methods. Generalized MB was diagnosed in 83 patients with HIV, patients. 57.8% (48 people) were men, while 42.2% (35 people) were women. The average age of patients was 39.2 years (from 19 to 63 years).

Results. The M. avium complex was the main etiological agent of generalized MB in HIV patients (97.6%). The most frequent clinical manifestations included fever (80/83 (96.1%)); abdominal discomfort and pain, diarrhea (53/83 (63.8%)), and decreased body weight (56/83 (67%)). The median CD4+ count in the group was 50 cells/μL. In 52% (43/83) of cases, generalized MB developed concurrently with other opportunistic or secondary infections (CMVI, pneumocystis pneumonia, and candidiasis). In 70% of cases (55/78), NTMs were isolated from two or more biological specimens. The positive result of blood culture for NTM had the greatest clinical significance (in 32/60 (53%) of the examined patients).

Published: November 2024

The objective: to determine the role of the rpoB Leu430Pro mutation in the degree of phenotypic resistance of Mycobacterium tuberculosis to rifampicin.

Subjects and Methods. The WHO classifies the rpoB Leu430Pro mutation of Mycobacterium tuberculosis as a borderline resistance mutation but of clinical significance. From an array of cultures, we selected and analyzed 14 isolates of M. tuberculosis with discrepancies in the results of molecular genetic and phenotypic testing, carrying only this mutation in rpoB. For all samples, the phenotypic resistance level (MIC) of these isolates to rifampicin was determined using BACTEC MGIT 960 and Middlebrook 7H11 medium.

Results. It was found out that 12 of 14 isolates had the rifampicin MIC below the current critical concentration when tested by both methods, thus they were phenotypically sensitive. One isolate was resistant when tested with Middlebrook 7H11 but susceptible when tested with BACTEC MGIT 960. Only one isolate which had the additional rpoB F425L mutation demonstrated high-level phenotypic resistance when tested by the same tests. Our data indicate that the clinical significance of this mutation requires clarification since even a decrease in the critical concentration of rifampicin does not lead to unambiguous results of molecular genetic and phenotypic tests. It is necessary to standardize the use of various molecular genetic tests and principles of their clinical interpretation to optimize strategies for managing patients with tuberculosis caused by M. tuberculosis with the rpoB Leu430Pro mutation.

Published: November 2024

This paper presents two examples of recently completed residential buildings in Belgrade and Velika Remeta (Irig Municipality). These buildings exemplify how flexibility is applied in contemporary housing designs in line with users' needs. The urban and architectural composition reflects a design approach considering contextual constraints and form-functional requirements to achieve an optimal housing standard. The implementation of the flexibility concept in the selected examples is considered in the design phase: (1) in the first example, flexibility refers to the use of the entire structure, not just the apartment unit, and (2) in the second example, flexibility is applied in the conceptual phase of the design process through the offer of seven variant types of the same design.
The right to privacy and the protection of patients' personal data
Authors: Jonev-Ćiraković Katarina
Published: November 2024

Globalization and accelerated technological development have led to new challenges in the protection of personal data. The Internet holds vast amounts of information, which at any moment is at risk of potential misuse on various websites, social networks, and platforms. The adoption of the EU General Data Protection Regulation (GDPR) marked a significant step in addressing this issue. Data related to the health sector-specifically, patients' personal data-are particularly sensitive. The concept of personal rights and their protection stems from the belief in universal values that apply to every individual. Safeguarding patient privacy is essential for preserving freedom and upholding fundamental human rights. It is crucial to define the scope and limitations of this protection, balancing the legitimate interests of third parties, society, and the state on one side, with the individual rights and interests of the patient on the other. In this context, recent amendments in European and Serbian legislation regarding personal data protection represent a cornerstone for this research, which holds significance for both legal and medical science, as well as practical application.

Authors: Sudhir Jain , Sundaramahalingam Athimoolam , Sudhagara Rajan , Muthiya Solomon , Chethan K.N. , Laxmikant Keni
Published: November 2024

The effect of poor air quality on human health has been linked to both short-term and long-term exposure to air pollutants. One of the most important steps in reducing emissions is accurate identification of these pollutants. This can be achieved by using Internet of Things equipped remotely operated airships that can survey large areas and gather pollution data. The ability of an airship to function at low altitudes for extended periods is the main design requirement of airships. This study describes a methodology for conceptualizing and building a helium-filled blimp for remote measurement of atmospheric pollutants (Carbon monoxide, Carbon dioxide, and Sulphur dioxide), temperature, and pressure. An onboard telemetry system measures the data while the airship is in flight and transmits them in real time to a ground-based station. The experiment showed that remotely operated airships are capable of gathering air data and their quality, enabling environmental scientists and regulatory agencies to better understand the behaviour of air pollutants and take steps to mitigate them.

Published: November 2024

Copper is largely used for heat transfer devices and electrical machines where high thermal and electrical conductivities are required. Since the performance can be further enhanced through design optimization, Additive Manufacturing (AM) represents a promising solution for the fabrication of complex Cu components for these application fields. 3D micro-extrusion, in particular, is an indirect AM technology that allows the fabrication of dense copper parts using a multiple-steps approach. The shaping of a green body upon extrusion of a highly powder-loaded paste is followed by a consolidation or post-processing treatment step. This includes the removal of the binder and densification through conventional sintering. The present study investigated the impact of the post-processing conditions on pure copper components fabricated by 3D micro-extrusion of different feedstock paste formulations. Multiple sintering atmospheres and thermal cycles were tested to assess their influence on the physical and functional properties of pure Cu material.

Review Of Non-Traditional Sinter-Based Metal Additive Manufacturing Technologies
Authors: Bose Animesh
Published: November 2024

Sinter-based metal additive manufacturing (AM) processes that decouple the geometric shaping and consolidation of AM have several advantages over melt-based AM technologies (one-step consolidation and shaping). The sinter-based AM technologies, led by binder jetting, has the potential to significantly increase the productivity and attain more isotropic microstructures in the final product. Sinter-based AM includes the ability to cover a wide spectrum of productivity, including prototyping, low volume serial production, and high-volume mass production. Recently, several non-traditional sinter-based metal AM processes (relatively less common) have emerged. This paper will review some of these emerging and lesser-known sinter-based metal AM technologies along with a few processes based on modifications of binder jet and material extrusion techniques that have gained traction.

Powder metallurgy and HIP (P|M HIP) provides dense materials with fine-grained microstructures and isotropic mechanical properties, which compete well with the mechanical properties of forged materials. In the nuclear industry, it is thus a credible solution to maintain the performance and the competitiveness of the nuclear power plants. However, the manufacturing of nuclear components is submitted to close control and traceability in order to achieve a high standard of metallurgical quality. This includes HIP parameters (temperature, pressure and time) to densify the powder. In this study, the influence of HIP temperature between 1373K and 1473K on the densification of a 304L nitrogen-atomised powder was addressed. According to the microstructures and the mechanical properties of the P|M samples (tensile tests and KV impact toughness), we propose a HIP temperature of 1433K to densify this powder. This temperature is in agreement with the recommendations formulated in the industry to densify 304L powder.

The use of different steel powders allows to obtain either multi-material junctions, when they are stacked, or new duplex alloys when they are blended.This study focuses on new materials obtained by Spark Plasma Sintering (SPS) or Hot Isostatic Pressing (HIP) with an austenitic 316L steel and a martensitic Fe-9Cr steel powders. These materials are characterized at different scales: from metallography to electron microscopy with EDX and EBSD, hardness and tensile tests.The mechanical behaviour of materials cannot be described by a simple law of mixtures. To better understand this phenomenon by describing the obtained materials as a composite, Reuss and Voigt models are used and discussed.The microstructural characterizations show that during the consolidation, the diffusion of the chemical species modifies the nature and the amount of phases, which makes it possible to understand why the models do not completely account for the experimental behaviour.

The microstructure of materials used in high-temperature components such as power generation, aerospace, chemical, and process plant applications must be stable at the service conditions to avoid any losses in the performance. The reduction of density and the increase of the thermal stability range of the microstructure are also two critical improvements to consider in the development of new dual Co-based superalloys. This work explored three viable choices for achieving dual ?|?’ microstructures: the Co-Al-Mo, the Co-Ni-Al-Ta-Ti-V, and the Co-Ti-V. Since the microstructural characteristics of Co-reinforced by ?' superalloys are critical for the envisioned next-generation superalloys, the morphology and coarsening behaviour of the ?' precipitates in each alloy during the sintering process have been investigated. The volume fraction of ?' and whether there is a difference in the coarsening rate of the ?' precipitates are also key factors in the behaviour of these alloys at high temperatures, has been promoted.

Although micro powder injection molding (MicroPIM) represents a strong technological task it becomes even more difficult in case of free-formed geometries. A challenging example are micro-sized test particles. Such artificial specimen are required for modelling and simulation of wear effects caused by manufacturing debris|swarfs occuring in e.g. journal bearings or combustion engines.The free-formed geometry was derived from a real manufacturing swarf previously characterized by 3D- CT. Micro mold insert design incorporating the free-formed surfaces was comprehensively simulated and realized by milling and discharge machining. For the first time in MicroPIM, specially tailored feedstocks containing 42CrMo4 steel powders were applied. The related molding, debinding, and sintering procedures had to be developed, too.The damage potential of the test particles was evaluated based on trials using journal bearing and shift valve test rigs. Thereby, it could be ascertained that the artificial swarfs will allow for development of standardized wear test procedures.
Laser Cladding With Conical Beams
Authors: Chivel Yuri
Published: November 2024

Laser cladding process with powder or wire should be an outstanding performer in additive manufacturing The new approach in selective laser cladding using conical laser beams has been elaborated. Initial circular laser beam is divided into two annular beams with regulated distribution of the laser power throughout the annular beams. Annular beams are transformed to conical beams , which are focused separately on the surface and on the deposited material for heating. The laser energy delivery to powder stream is very efficient because a total uniform absorption of laser energy in the dense powder stream ( 104-105 1|cm3). Under wire deposition the heating of substrate reduces the residual stresses due the reduction temperature gradients and compensates heat losses from deposition zone. The power density for melt contact formation is significantly reduced as well as dissolution, while increasing accuracy. The optimal regimes of laser cladding can be achieved using new approach.

Published: November 2024

Different AM technologies such as PBF-LB and DED do become really attractive for both repair and 3D part manufacturing. In particular, extensive work is in progress for the non weldable nickel-based superalloys which tend to exhibit cracks due to residual stresses build-up during AM thermal cycles. Within the framework of the project FAPS conducted at Paris-Saclay, the present investigation will highlight the processing conditions and build-up strategy that produce crack-free specimens for alloy AD730. The latter was developed by Aubert&Duval for cast+wrought gas turbine applications. In this work, a comparison between such conventional processing and AM will be provided in terms of mechanical performance. The results clearly show an anisotropic behaviour related to the sharp crystallographic texture induced by the epitaxial grain growth. The results will be discussed, with a perspective analysis of maturity for this AM processed-material, the process robustness, the potential technological developments and application prospects.

FAST|SPS-KOBO manufacturing technology is being developed within the Horizon 2020 project (LightMe) as a promising route for manufacturing aluminum alloy profiles. The main advantages of applying the KOBO cyclic extrusion severe deformation technique are the reduction of the processing energy and the great increase in intensity of the deformation and dynamic recrystallization processes. The SPS technique for manufacturing fully dense AA7075-3wt%nSiC metal matrix composite (AAMC) cylindrical preforms, followed by KOBO extrusion at ambient temperature allows the production of rods 8 mm in diameter and 800–1000 mm in length with a trimodal structure. The microstructure and mechanical properties of the AA7075-3nSiC composites with a bimodal grain laminated microstructure are investigated. The manufactured rods are characterized by a yield strength of >400 MPa, ultimate tensile strength of >510 MPa, tensile strain of 5.4–11% and Vickers hardness of approx. 1.2 GPa.

To enhance the properties of tungsten diboride, solid solutions of this ceramic with transition metals such as titanium, zirconium, and tantalum were synthesized by spark plasma sintering from the pure elements. The metallic content was in all cases 24 at.%. The specimens were characterized using scanning electron microscopy and energy-dispersive X-ray spectroscopy for microstructure analysis, X-ray diffraction for phase identification as well as measurements of density and electrical conductivity. Based on the analysis of sintering curves, two stages of reactive spark plasma sintering were observed. For instance, in the W0.76Ta0.24B2 sputtering target, the WB2 and TaB2 phases were synthesized. The density changes along the diameter from 8.99 in the center to 8.29 g|cm3 on the border of the disc. The usable properties of the obtained materials mean that W-TM-B compounds may be used such as sputtering targets for high-power impulse magnetron sputtering.
