Religious Affiliation as a Political Site of Contestation? Polemical Voices of a New Generation of Romanian Romani Authors*
Authors: Zăloagă Marian 
Published: March 2023

Abstract
The 1990s and the early 2000s was a period of revitalization of the Romani studies in Romania. Participants in the process were non-Roma as well as Roma authors. The religious practices and the affiliations of the Romanies was regarded to be a significant matter to start building a dignified profile of the ethnic group from the perspective of the in - group members who ventured to participate in knowledge production,. If a first generation of Roma intellectuals were more concerned to find corelations and provide explanations in a more or less essentialized fashion, the analysis of the scientific literature authored by a young generation of the in-group members indicate a certain tendency to over-politicize the topic of religiosity and the religious affiliation of the Romanian Romanies. In the process, the Romanian Orthodox Church has been turned into a target. Specifically, the acknowledgment that the dominating religious actor from Romania took part in the perpetuation of the state of slavery of the Romanies makes the Romanian Orthodoxy vulnerable to a series of recent public attacks. This inglorious past is used to symbolically and rhetorically justify the ongoing reaffiliation of the Romanies to neo-Protestant churches. Recognizably, the politicization of the religious affiliation of the minority group was started by a first generation of Romanian Roma intellectuals and the young generation only intensified their attacks. If one considers the in-group knowledge production in a comparative manner, one can realize that a first generation of Romanian Roma intellectuals found it reasonable to accommodate the Romanipen to the religious background dominating in Romania, while a young generation has chosen to overtly and loudly confront the national hegemon religious institution. This is the main trend, but, as I will demonstrate it is not at all a unique approach to the religiosity of the Romanies as undertook by in-group voices. Some Romanian Roma authors have preferred to re-write back to their ethnic and generational peers and to take side with the Romanian Orthodox Church. In their research, the Romanies end up being blamed by a mendacious relation to the religious institution to which the majority Romanian population has been affiliating for centuries. At the same time, the neo-Protestant churches are suspected to act superficially and their missionary work among the Roma communities could be indirectly suggested to represent the convenient meeting ground between two religious scammers.
In the present paper I discuss to what extent the new generation of Romanian Roma intellectuals have considered suitable to weaponize the knowledge production on this specific matter and outline the political stakes behind the arguments employed to carry this symbolical and rhetorical battle between in-group narratives.
Chrysoprase – history and present

Published: March 2023

Abstract
The authors present the history of chrysoprase discovery and the progress of knowledge about this material over the millennia, based on the extended review of world literature. Tracing the oldest archaeological artifacts from before 9,000 years, the lens of history turns on a stone that has not been properly identified mineralogically for centuries. In the 1830s, chrysoprase was finally included into the chalcedony group and its green color was associated, very correctly, with nickel compounds dispersed in its structure. After all, the most current mineralogy of chrysoprase is presented on the basis of the results of modern analytical studies. These data clearly indicate that chrysoprase is a mixture of several SiO2 polymorphs with varying degrees of structural order (opal, chalcedony, moganite, quartz). This radically changes the previous taxonomy of chrysoprase and its position in current mineralogical and petrographic systematics.

Abstract
This work reported the successful synthesis of ilmenite-spinel (1 − x)NiTiO3-xMnFe2O4 (x = 0, 0.05 and 0.10) composites by a simple sol-gel method. Phase formation of composites was analyzed by the X-ray diffraction method. All the synthesized samples formed diphasic ilmenite-ferrite composites without any trace of impurity or intermediate phase. The optical properties of synthesized composites were characterized by diffuse reflectance UV–visible spectroscopy. MnFe2O4 phase modified the optical band gap of NiTiO3 material and shifted its optical bandgap value toward lower energy. Ferroelectric and magnetic hysteresis loops were investigated at room temperature. The hysteresis loops indicated the typical ferromagnetic and ferroelectric nature of all composites at room temperature. In P-E loops, the remanent polarization (Pr
) and saturation polarization (Ps
) showed a slight increase in the sample with 5% MnFe2O4 phase addition. However, the lossy P-E loop was observed in the sample with the addition of 10% MnFe2O4. The presence of ferrite MnFe2O4 phase in NiTiO3 material enhanced the magnetic properties of NiTiO3 at room temperature. The M-H loops of NiTiO3-MnFe2O4 composites presented a ferromagnetic behavior with a dramatic increase in saturation magnetization with an increase of ferrite phase addition.

ABSTRAK

Nitrogen memiliki peranan utama dalam proses pertumbuhan tanaman. Namun, keberadaan dan ketersediaan nitrogen di dalam tanah terbatas, karena mudah hilang dan terbawa air, sehingga menyebabkan efisiensi pemupukan nitrogen yang rendah. Peningkatan efisiensi pemupukan nitrogen dapat diupayakan melalui formulasi pupuk dalam bentuk slow release fertilizer (SRF) dan pemberian unsur nitrogen dalam jumlah yang banyak. Tujuan dari penelitian ini adalah untuk mengetahui pola pelepasan nitrogen total dalam tanah setelah terikat pada bentonit teraktivasi asam yang terlapisi amonium nitrat. Pada pembuatan SRF, pelapisan amonium nitrat pada bentonit teraktivasi dilakukan dengan perbandingan massa (gram) 20:20. Penentuan kadar nitrogen total dilaksanakan menggunakan metode Kjeldahl. Hasilnya menunjukkan bahwa SRF 20 memiliki kandungan nitrogen total tertinggi sebesar 0,77%. Karakterisasi SRF 20 menggunakan FTIR mengindikasikan adanya amonium nitrat yang terikat pada SRF 20. Gugus fungsi yang menyatakan adanya ikatan amonium nitrat pada SRF 20 adalah C-O dan N-H. Untuk pengulangan 1, 2, dan 3 selama 7 hari leaching, nitrogen total yang terlepas masing-masing sebanyak 0,0051; 0,0075; dan 0,0067 gram dengan sisa nitrogen 0,61; 0,60; dan 0,60 gram. Hal ini membuktikan bahwa nitrogen berhasil terperangkap dalam permukaan maupun struktur pori-pori adsorben, yaitu bentonit teraktivasi.

ABSTRACT

Nitrogen has a major role in the process of plant growth. Unfortunately, the presence and availability of nitrogen in the soil are limited because nitrogen is easily lost and carried away by water causing low nitrogen fertilization efficiency. Increasing the efficiency of nitrogen fertilization can be pursued through the formulation of fertilizer in the form of Slow Release Fertilizer (SRF) and the application of nitrogen in large quantities. The purpose of this study was to determine the total nitrogen release pattern in the soil after being bound to acid-activated bentonite coated with ammonium nitrate. In the preparation of the SRF, the activated bentonite was coated by ammonium nitrate with a mass ratio (grams) of 20:20. The tests for determining the total nitrogen content were done using Kjeldahl method. The results showed that SRF 20 had the highest total nitrogen content of 0.77%. The characterization of SRF 20 using FTIR revealed that the ammonium nitrate bound to the SRF 20. The functional groups indicating the presence of ammonium nitrate in the SRF 20 were C-O and N-H. In repetitions 1, 2, and 3 for 7 days of leaching, the total nitrogen released was 0.0051; 0.0075; and 0.0067 grams, with nitrogen remaining 0.61; 0.60; and 0.60 grams, respectively. This proved that nitrogen was successfully trapped in the surface and pore structure of the adsorbent, activated bentonite.

Seeking Education, Equity, and Diversity (Seed)
Authors: Ackles Crystal , Michael E. Anders, Ph.D  
Published: March 2023

Introduction
Health care work cultures that embrace diversity, equity, and inclusion (DEI) foster innovations, synergy, and appreciation for differences. To promote DEI, health care systems have encouraged professional development on cultural humility, which is awareness of one’s values, beliefs, and social position, given the current cultural context while mindful of history. The national SEED Project (Seeking Educational Equity and Diversity) is a professional development program that prompts reflection and perspective shifting about workplace culture and systemic change. However, reports that examine the SEED learning experience and the participants’ intention for behavior change are lacking. The purpose of our study was to examine: (a) The SEED learning experience, (b) How personal views can foster cultural humility, and (c) The impact of SEED on intentions to effect change.
Methods
A purposive sample of eight (N = 8) faculty and staff from a SEED cohort at an academic health science center, with regional programs, participated in in-depth interviews to explore their personal views of how to foster cultural humility in health care and the impact of SEED to prompt intentions for behavior change. The investigators conducted a thematic analysis using an inductive, iterative method. Independently, they read each transcript and created codes for each comment. Subsequently, they compared findings, developed a coding frame, and grouped codes into potential themes. They then individually applied the coding frame to the data and considered themes. Finally, they built consensus on codes and synthesized codes into themes.
Results
Thematic analysis indicated the participants had a profound learning experience, which prompted them to develop cultural humility by re-framing cultural experiences and resolving to become more proactive about DEI in the workplace. They found small group discussions were insightful and provocative. These discussions led to new perspectives and behavior change or intentions for behavior change. Our analysis generated three themes: (1) Connecting with diverse perspectives, (2) Developing new perspectives, and (3) Being proactive with advocacy and new strategies.
Conclusion
Health care professionals and organizations can use our findings to encourage professional development that potentially stimulates behavior change, the ultimate goal of professional development, related to DEI. Future studies should examine the impact of this professional development within their organization and in the delivery of health care.

Pucuk merah (Syzygium myrtifolium Walp.) is an ornamental plant from the Myrtaceae family. Several phytochemical tests from previous researchers reported that pucuk merah contains secondary metabolites that have benefits such as antioxidants, antibacterials, and anti-cancer. In addition, the distinctive aroma produced from pucuk merah leaves indicates the presence of essential oils whose bioactivity can be studied. Still, there has been no report on this plant's chemical components or bioactivity. Therefore, this study aims to determine the content of chemical components of pucuk merah essential oil and their bioactivity as antibacterial and toxicity. The isolation of essential oils was carried out by the hydro distillation method. The chemical components of essential oils were analyzed using the Gas Chromatography-Mass Spectrometry (GC-MS) method. GC-MS results showed the presence of 42 compounds with four main compounds, namely caryophyllene (23.45%), 3-carene (15.67%), α-terpineol (10.74%), and α-pinene (5.98%) ). Antibacterial test of pucuk merah essential oil using the disc diffusion method showed strong activity against Staphylococcus aureus and Escherichia coli with inhibition zones of 16.15 ± 2.03 and 16.13 ± 1.74 mm at 100% concentration. The results of the toxicity test of pucuk merah essential oil using the BSLT (Brine Shrimp Lethality Test) method on Artemia salina Leach shrimp larvae showed strong toxic properties with an LC50 value of 3.99 µg/mL.
A challenging recurrent thoracic disc herniation
Authors: Capece Mara , Corazzelli Giuseppe , Pizzuti Valentina , Leonetti Settimio , Innocenzi Gualtiero 
Published: March 2023

Background:
Thoracic disc herniations are rare and occur at the rate of 1/1,000,000/year. Surgical approach must be individually tailored to the size, location, and consistency of the herniated disc. Notably, here, we report the unusual recurrence of a thoracic herniated disc.

Case Description:
In 2014, a 53-year-old female presented with thoracic back pain, and paraparesis, attributed to an magnetic resonance imaging/computed tomography (CT)-documented left paramedian T8–T9 calcific disc herniation. She underwent a left hemilaminectomy/costotrasversectomy following which she experienced complete regression of her symptoms. Notably, the postoperative radiological studies at that time demonstrated some residual although asymptomatic calcific disc herniation. Eight years later, she again presented, but now with the chief complaint of difficulty breathing. The new CT scan showed a new calcified herniated disc fragment superimposed on the previously documented residual disc. Through a posterolateral transfacet approach, she underwent resection of the disc complex. An intraoperative CT scan confirmed complete removal of the recurrent calcified disc herniation. Following the second surgery, the patient fully recovered and remains asymptomatic.

Conclusion:
A 53-year-old female first presented with a left-sided T8/T9 thoracic calcified disc herniation that was initially partially resected). When another larger fragment appeared 8 years later, superimposed on the previously documented residual disc, it was successfully removed through a posterolateral transfacet approach completed with CT guidance and neuronavigation.
Giant Tarlov Cyst presenting as pelvic mass: Often doing less is better

Published: March 2023

Background:Tarlov cysts are sacral perineural cysts arising between the peri and endoneurium of the posterior spinal nerve root at the Dorsal Root Ganglion and have a global prevalence rate of 4.27%. These are primarily asymptomatic (only 1% with symptoms) and typically arise in females between the ages of 50–60. Patients’ symptoms include radicular pain, sensory dysesthesias, urinary and/or bowel symptoms, and sexual dysfunction. Non-surgical management with lumbar cerebrospinal fluid drainage and computerized tomography-guided cyst aspiration typically provide only months of improvement before recurring. Surgical treatment includes a laminectomy, cyst, and/or nerve root decompression with fenestration of the cyst and/ or imbrication. Early surgery for large cysts provides the longest symptom-free periods.Case Description:A 30-year-old male presented with a very large magnetic resonance-documented Tarlov cyst (Nabors Type 2) arising from bilateral S2 nerve root sheaths with marked pelvic extension. Although he was initially treated with a S1, S2 laminectomy, closure of the dural defect, and excision/marsupialization of the cyst, he later required placement of a thecoperitoneal shunt (TP shunt).Conclusion:A 30-year-old male with large Nabors Type 2 Tarlov cyst arising from both S2 nerve root sheaths required a S1-S2 laminectomy, dural closure/marsupialization, and imbrication of the cyst, eventually followed by placement of a TP shunt.
Direct methods for modeling vehicle traffic in the surrounding of a reinforced slope
Authors: Panasiuk Leonid , Tyurina Vasilina 
Published: March 2023

The dynamic impact of moving vehicles can cause effects leading to landslide processes in slopes. Even insignificant displacements and speeds lead to a relative displacement of the layers. In this case, the physical and mechanical parameters of the soils that make up the slope can change significantly. For example, the decrease in adhesion C may be analogous to the decrease in the force of static friction by the transition to sliding friction. This is due to the fact that the mutual movement leads to slippage of small soil fragments relative to each other. The influence of vehicles on possible landslide processes increases with an obvious tendency to increase the speed and mass of the rolling stock. This, as well as the complex geological structure of the slopes and the need to take into account the reinforcing structures, leads to the need to build refined mechanical and mathematical models for the joint operation of road structures, the slope and the reinforcing structures in a dynamic formulation.
The creation of a refined model of the slope geometry, the highway and the slope reinforcement structures are today solved mainly by the finite element method (FEM). The problem of constructing a numerical solution of such problems based on direct methods of integrating the equations of motion is topical. In this case, it is necessary to take into account the change in the distribution of masses when moving vehicles along the road at different speeds.
In any of works of the author [1-6], an explicit absolutely stable scheme for integrating the equations of motion of the FEM was used to solve this problem.
This article considers testing of the method by comparing numerical solutions with known ones for problems that are simpler in terms of topological structure. Namely, the comparison of the method with the solutions of the classical problem "movement of a massive load along a massive beam" was carried out. V.V. Bolotin's solution [7-9] was adopted as a "reference" one. Numerical solutions showed a high degree of convergence of results by the proposed and "reference" methods.
