Authors: Φλώρου Χρυσούλα
Published: April 2024

Σκοπός: Η εκτίμηση των μορφολογικών ιδιοτήτων των ενδοθηλιακών κυττάρων του κερατοειδούς καθώς και του κεντρικού πάχους αυτού (CCT) σε ασθενείς με νευροϊνωμάτωση τύπου 1 (NF1) και να τους συγκρίνουμε με υγιείς ματσαρισμένους ως προς την ηλικία. Μεθοδολογία: Οι 19 NF1 ασθενείς και οι 38 υγιείς που συμμετείχαν στη μελέτη, υπεβλήθησαν σε πλήρη οφθαλμολογικό έλεγχο και κατοπτρική μη-επαφής μικροσκοπία για τον υπολογισμό της πυκνότητας των ενδοθηλιακών κυττάρων (ECD), του συντελεστή μεταβλητότητας του μεγέθους των κυττάρων (CV), του μέσου όρου του μεγέθους των κυττάρων (AVG), του ποσοστού εξαγωνικότητας των κυττάρων. και του CCT. Οφθαλμοί με προηγούμενο οφθαλμικό τραύμα, φλεγμονή ή χειρουργείο και προϋπάρχοντα νοσήματα του κερατοειδούς και της οφθαλμικής επιφάνειας αποκλείστηκαν. Αποτελέσματα: Οι NF1 ασθενείς είχαν μεγαλύτερη ECD σε σύγκριση με τους υγιείς ίδιας ηλικίας (2764.2 ± 270.4 έναντι 2570.4 ± 449.2 cells/mm2, αντίστοιχα) αν και σε οριακό επίπεδο (P=0.051). Οι NF1 ασθενείς είχαν στατιστικά σημαντικά χαμηλότερο CV και AVG σε σύγκριση με τους υγιείς (32.9 ± 4.6 έναντι 37.8 ± 9.5%, P = 0.011 και 364.9 ± 34.4 έναντι 406.0 ± 107.4 µm2 , P = 0.038, αντίστοιχα). Οι NF1 ασθενείς είχαν στατιστικά σημαντικά υψηλότερο ποσοστό εξαγωνικότητας συγκριτικά με τους υγιείς (55.7 ± 6.5 έναντι 50.5 ± 9.9%, P = 0.025). Το CCT ήταν ίδιο μεταξύ των δύο ομάδων (P=0.955). Συμπεράσματα: Τα ευρήματα μας δείχνουν ότι το ενδοθήλιο του κερατοειδούς έχει πιο ευνοϊκά μορφολογικά χαρακτηριστικά στους NF1 ασθενείς σε σύγκριση με τους υγιείς της ίδιας ηλικίας.Επίσης, παρουσιάσαμε ένα περιστατικό ανώδυνης επιπεφυκοτικής μάζας στον κόγχο εξαιτίας μη-Hodgkin λεμφώματος Β-κυττάρων χωρίς συστηματική συμμετοχή σε έναν 76-χρονο άνδρα. Αφού πραγματοποιήθηκε βιοψία εκτομής , ιστοπαθολογική εξέταση και ανοσοϊστοχημικός έλεγχος, ο ασθενής παραπέμφθηκε για αιματο-ογκολογική εκτίμηση. Στη συνέχεια, υποβλήθηκε σε εργαστηριακές και απεικονιστικές εξετάσεις και έλαβε συνδυασμένη χημειο-ανοσοθεραπεία που οδήγησε σε πλήρη ύφεση μέχρι σήμερα. Το περιστατικό αυτό παρουσιάστηκε καθώς είναι κρίσιμης σημασίας να αναγνωρίζουμε ότι μπορεί να εμφανιστεί προσβολή του επιπεφυκότα σε NF1 ασθενείς.

Did the Maids Return? The Long History of Devaluing Care Work and the Mixed Economy of Welfare
Authors: Kramer Nicole
Published: April 2024

For several years now, sociologists studying paid domestic care work have been arguing that the servant culture of the nineteenth century has returned. They focus on specific forms of care work: that done as informal or illegal employment, mostly carried out by migrants. To an historian, such a reference to the past is most intriguing. This article looks at the servant of the past to shed new light on the emergence of an informal labour market for care work. After outlining the arguments of sociologists about “the return of the maids”, it looks back at the history of servants. What was their role regarding long-term care for older disabled people? Furthermore, it sketches the changes regarding professional care at home and, finally, sheds some light on the emergence of a shadow market where migrants offer their services. In doing so, families should be brought into focus as agents of care within the mixed economy of welfare.

Twelve tips for final year medical students undertaking clinical assessment
Authors: Malau-Aduli Bunmi S , Hays Richard B , Saad Shannon , D'Souza Karen
Published: April 2024

Background Clinical assessors in pre-registration examinations have been shown to make decisions about student performance by drawing on two overlapping, yet slightly different perspectives: achieving academic learning outcomes, and contributing to clinical workplace function. The implication for senior medical students is that they should be aware that in ‘final’ clinical assessments they may be judged from both academic and workplace perspectives, where the emphasis may be on how well the candidate would fit into a clinical team, demonstrating reliability, trustworthiness, teachability and ‘safety’. Methods This article presents 12 tips for how senior medical students may demonstrate progress towards achieving ‘work readiness’, and so improve performance in assessments close to graduation. Results Clinical assessors may include judgment of how well the candidate might work as a junior member of a clinical team, particularly when candidates perform at the borderline level and where assessors are more experienced. This judgment is based on an impression of the student’s demonstration of reliability, trustworthiness, patient safety and teachability. While the underpinning theory was explored in final OSCEs, the suggestions may also be relevant to workplace-based clinical learning and assessment. Conclusions Senior medical students should prepare for clinical assessments that will consider more than essential knowledge and skills.
Czarna elita marszałka Rokossowskiego. Rozwój wojsk pancernych Ludowego Wojska Polskiego w latach 1947-1956
Authors: Piotrowski Paweł
Published: April 2024

The article addresses the issue of the actual development of the modern branch of the armed forces at the turn of the 1940s and 1950s, namely the armored and mechanized land forces. In 1948, the reduced army consisted of six tank regiments and four armored artillery regiments, with a total of just under 300 combat vehicles, significantly overused and in need of repairs. With the appointment of the Soviet marshal Konstanty Rokossowski as the minister of national defense of the Polish People’s Republic, and with the assistance of Soviet generals and armor officers, a large-scale expansion of the army was initiated, including armored and mechanized forces. The result was the presence, in 1956, of eight armored and mechanized divisions in the Polish People’s Army, comprising over 2200 tanks and self-propelled artillery vehicles, mostly produced in the first half of the 1950s. This constituted a modern army by the standards of that time, representing a significant force in the Central European theater of military operations.
„Melduję, że jest to praca psychicznie trudna do pogodzenia dla każdego człowieka”. Uwagi do funkcjonowania Misji Polskiej w Komisji Nadzorczej Państw Neutralnych w Korei do roku 1989
Authors: Benken Przemysław
Published: April 2024

The article describes several selected problems in the current functioning of the Polish Mission in the Neutral Nations Supervisory Commission in Korea from 1953 to 1989. The commission oversaw the observance of the armistice signed on 27 July 1953 in Panmunjom, where its headquarters were located, right in the middle of the demilitarized zone. Due to the limited space, the focus is on describing only selected threads related to the commission’s activities. The article describes the selection of suitable candidates from the ranks of the socalled Polish People’s Army for the Polish Mission to the NNSC under the supervision of military intelligence; working conditions in Korea; and sometimes troublesome relations between the commission’s members and hosts from the Democratic People’s Republic of Korea.

„Zums Maul einen stein und unter den Zunge einen heller legen” – wierzenia w szkodliwą aktywność zmarłych na Śląsku na przykładzie wydarzeń z 1595 r. z Witkowa koło Kamiennej Góry
Authors: Wojtucki Daniel
Published: April 2024

The term “posthumous magic” (Magia posthuma) became widespread only in the early 18th century. It refers to a phenomenon related to ancient beliefs in returning deceased individuals who could harm the living. From a preserved judicial book covering the years 1538-1643 and the chronicles of the Krzeszów estates, we know of two cases of the malevolent dead that occurred in 1595 and 1668 in Witków near Kamienna Góra. These events caused great concern among the local population and subsequently, among the higher authorities, who were approached for help and intervention. In both cases, the local court informed the higher authorities about complaints regarding unexplained, terrifying events in the village and the remedial measures taken in connection with them. In relation to the events of 1595, a specific couple of deceased individuals were accused of malevolent actions. In 1668, an old dead woman was the culprit. Despite several decades separating the two events, the common denominator was accusations of witchcraft, that is, black magic. In both cases, the exhumation of the bodies and the burning of the corpses retrieved from the graves at the outskirts of the village were ordered. Along with the cremation of the deceased, the local population was no longer plagued by unexplained phenomena.
Stanowisko jednostek Związku Pobożnego pod marszałkiem Aleksandrem Ludwikiem Niezabitowskim przed sejmem walnym w Warszawie w 1662 roku
Authors: Nagielski Mirosław
Published: April 2024

Związek Pobożny, formed under the inspiration of officers associated with the royal court, mainly Stefan Czarniecki, the Voivode of Kijów, in January 1662 at the camp near Czereja, was intended to counterbalance the Związek Święcony Union that gathered the majority of the cavalry from the national enlistment, which vehemently advocated for the acknowledgement of their accomplishments and criticized the royal couple’s policies. The instructions issued by Związek Pobożny during the general sejm in 1662 mainly contained demands related to the lack of payments for the troops since the war with Sweden and recommendations for deserving officers regarding rewards, naturalization, and nobility for their military achievement. Delegates of this union did not play a significant role at the 1662 sejm, as the commissioners of the Commonwealth held talks with the delegates of Związek Święcony, who also opposed the plans of the court to promote the election vivente rege banned at the 1661 sejm. However, it reflects the position of Stefan Czarniecki’s division, which played a significant role in the struggle of Jan Kazimierz against the opposition.
Z dziejów budowy kościoła Krzyża Chrystusowego w Lubaniu
Authors: Tekiela Łukasz
Published: April 2024

The construction of the Church of the Christ Cross in Lubań took place between 1703 and 1706 during the Great Northern War. The church was consecrated by Pastor Gottfried Edelmann, who gave it the name Christ Cross, referring to the difficult times the residents of Lubań faced when building the temple. It was the largest construction project carried out by the inhabitants of Lubań within the defensive walls, in the period between the construction of the town hall in 1539-1543 and the construction of the Holy Trinity Church in the mid-19th century. Despite numerous challenges, construction work progressed smoothly and on schedule. The coordination of most activities related to the construction of the church was led by the Lubań doctor Adam Kirchhoff. The role of the master builder was performed by the Poznań specialist Elias Schultze. The church significantly enriched the architectural, religious, and cultural landscape of the city.

CUSTOMS RECOGNITIONS AS A SOURCE FOR STUDYING THE HISTORY OF KAMIENIEC ARMENIANS IN THE SECOND HALF OF THE 16TH CENTURY

Armenians were among the constituent ethnic groups in the society of the Kingdom of Poland and the Grand Duchy of Lithuania. Actively participating in trade, they were subject to legal regulations in as much as other urban citizens. Customs recognitions, or testimonies given by merchants enjoying customs freedom, serve as evidence of this process. The article analyzes the overall trade activities of Armenians from Kamieniec Podolski [Kamianets-Podilskyi] at Lublin fairs based on these recognitions. On their basis, it discusses the significance of customs exemptions as one of the privileges of Kamieniec residents, as well as the intensity of trade relations between this city and Lublin, and the range of goods exchanged. Additionally, it addresses the Armenians’ knowledge of legal practices and their ability to use the Polish and Ruthenian languages. An annex includes the edition of customs recognitions, which are an interesting source for studying economic history, diplomatics, and sigillography.

Private Equity Exits in the CEE:
Authors: Bílek Michael
Published: April 2024

Purpose of the article: The purpose of this article is to assess private equity exit strategies of CEE portfolio companies with regards to desired exit routes, including a cross-border deal aspect and a pre-exit holding period.Methodology/methods: This paper employs secondary data from the Mergermarket database containing information on more than 20 thousand private equity M&A deals and IPOs. General scientific methods such as analysis, comparison or generalization were used.Scientific aim: Only limited amount of research was carried out on the private equity exits in the region of central and eastern Europe. This study aims at shedding new light on understanding of private equity exit route decisions and timing in this particular geographic area.Findings: Exiting a CEE portfolio company, private equity investors tend to prefer exiting via trade sales over secondary buyouts or IPOs. They also tend to prefer foreign acquirers over domestic ones. A typical pre-exit holding period averages around 5 years.Conclusions: Our results show that while exiting a CEE portfolio company, private equity investors tend to divest by selling the company to a strategic investor (trade sales) rather than a financial investor (secondary buyouts) or exiting via an IPO. While exiting via trade sales and secondary buyouts, private equity investors tend to prefer foreign acquirers rather than domestic ones with a strong preference of acquirers from outside of the respective region. Typical holding period of a CEE private equity portfolio company remains on average in line with academic theory. Our paper contributes to the developing literature of private equity by using an extended and up to date dataset and introducing the research on the cross-border aspect of PE exit strategies.
Improving the reliability of deep learning computational ghost imaging with prediction uncertainty based on neighborhood feature maps

Published: April 2024

Defect inspection is required in various fields, and many researchers have attempted deep-learning algorithms for inspections. Deep-learning algorithms have advantages in terms of accuracy and measurement time; however, the reliability of deep-learning outputs is problematic in precision measurements. This study demonstrates that iterative estimation using neighboring feature maps can evaluate the uncertainty of the outputs and shows that unconfident error predictions have higher uncertainties. In ghost imaging using deep learning, the experimental results show that removing outputs with higher uncertainties improves the accuracy by approximately 15.7%.
Model for partitioning the non-phytoplankton absorption coefficient of seawater in the ultraviolet and visible spectral range into the contributions of non-algal particulate and dissolved organic matter
Authors: Kehrli Matthew D. , Stramski Dariusz , Reynolds Rick A. , Joshi Ishan D.
Published: April 2024

Non-algal particles and chromophoric dissolved organic matter (CDOM)
are two major classes of seawater constituents that contribute
substantially to light absorption in the ocean within the ultraviolet
(UV) and visible (VIS) spectral regions. The similarities in the
spectral shape of these two constituent absorption coefficients, ad(λ) and ag(λ), respectively, have led to their
common estimation as a single combined non-phytoplankton absorption
coefficient, adg(λ), in optical remote-sensing
applications. Given the different biogeochemical and ecological roles
of non-algal particles and CDOM in the ocean, it is important to
determine and characterize the absorption coefficient of each of these
constituents separately. We describe an ADG model that partitions adg(λ) into ad(λ) and ag(λ). This model improves upon a recently
published model [Appl. Opt. 58, 3790
(2019)APOPAI0003-693510.1364/AO.58.003790] through
implementation of a newly assembled dataset of hyperspectral
measurements of ad(λ) and ag(λ) from diverse oceanic environments to
create the spectral shape function libraries of these coefficients, a
better characterization of variability in spectral shape of ad(λ) and ag(λ), and a spectral extension of model
output to include the near-UV (350–400 nm) in addition
to the VIS (400–700 nm) part of the spectrum. We
developed and tested two variants of the ADG model: the ADG_UV-VIS
model, which determines solutions over the spectral range from 350 to
700 nm, and the ADG_VIS model, which determines solutions in
the VIS but can also be coupled with an independent extrapolation
model to extend output to the near-UV. This specific model variant is
referred to as ADG_VIS-UVExt. Evaluation of the model with
development and independent datasets demonstrates good performance of
both ADG_UV-VIS and ADG_VIS-UVExt. Comparative analysis of
model-derived and measured values of ad(λ) and ag(λ) indicates negligible or small median
bias, generally within ±5% over the majority of the
350–700 nm spectral range but extending to or above 10%
near the ends of the spectrum, and the median percent difference
generally below 20% with a maximum reaching about 30%. The presented
ADG models are suitable for implementation as a component of
algorithms in support of satellite ocean color missions, especially
the NASA PACE mission.
Grating-free autofocus for single-pixel microscopic imaging
Authors: Wang Guan , Deng Huaxia , Cai Yu , Ma Mengchao , Zhong Xiang , Gong Xinglong
Published: April 2024

As a computational technology, single-pixel microscopic imaging (SPMI) transfers the target’s spatial information into a temporal dimension. The traditional focusing method of imaging before evaluation is not applicable to the SPMI system. We propose a grating-free autofocus strategy derived from the physical mechanism of optical defocus. Maximizing the amplitude information of just one high-frequency point in the spectrum is all that is needed to achieve fast autofocus with the SPMI system. Accordingly, only four patterns need to be cyclically projected, enabling efficient localization of the focal plane based on the measurement data. We demonstrate SPMI autofocus experiments at micrometer and even nanometer depths of field. The proposed method can be extended to achieve SMPI autofocus with invisible optical pattern illumination.
African swine fever virus pB318L, a trans-geranylgeranyl-diphosphate synthase, negatively regulates cGAS-STING and IFNAR-JAK-STAT signaling pathways

Published: April 2024

African swine fever (ASF) is an acute, hemorrhagic, and severe infectious disease caused by the ASF virus (ASFV). ASFV has evolved multiple strategies to escape host antiviral immune responses. Here, we reported that ASFV pB318L, a trans-geranylgeranyl-diphosphate synthase, reduced the expression of type I interferon (IFN-I) and IFN-stimulated genes (ISGs). Mechanically, pB318L not only interacted with STING to reduce the translocation of STING from the endoplasmic reticulum to the Golgi apparatus but also interacted with IFN receptors to reduce the interaction of IFNAR1/TYK2 and IFNAR2/JAK1. Of note, ASFV with interruption of B318L gene (ASFV-intB318L) infected PAMs produces more IFN-I and ISGs than that in PAMs infected with its parental ASFV HLJ/18 at the late stage of infection. Consistently, the pathogenicity of ASFV-intB318L is attenuated in piglets compared with its parental virus. Taken together, our data reveal that B318L gene may partially affect ASFV pathogenicity by reducing the production of IFN-I and ISGs.

Background and Aim: The use of bioengineered nanocomposites as antimicrobials has increased in recent years, but very few investigations have been conducted to test their effectiveness against Pseudomonas aeruginosa, a pathogen presenting public health risks that can impact both humans and animals. The aim of this study was to assess the antimicrobial potential of phytofabricated silver nanoparticles synthesized using lemongrass extract against clinical isolates of P. aeruginosa. Materials and Methods: The extraction of active compounds from the leaves of Cymbopogon citratus was performed using ethanol (80%) as a solvent, high-performance liquid chromatography-mass spectrometry was used to analyze the chemical composition of the extract, the synthesis of silver nanoparticles (AgNPs) was done using silver nitrate (AgNO3) as a precursor, and the antimicrobial and antibiofilm activity of the extract and the AgNPs phytofabricated was assessed against 10 clinical strains of P. aeruginosa. Results: Lemongrass extract was found to consist of the following main compounds: Caffeic acid (445.21 ± 32.77 μg/g), p-coumaric acid (393.32 ± 39.56 μg/g), chlorogenic acid (377.65 ± 4.26 μg/g), quinic acid (161.52 ± 17.62 μg/g), and quercetin-3-glucoside (151.35 ± 11.34 μg/g). AgNPs were successfully phytofabricated using 2.5 mM AgNO3. The ultraviolet (UV)-visible absorption spectra of the AgNPs showed a localized surface plasmon resonance at 464 nm with an absorbance of 0.32 A. The 50x hydrodynamic diameter was 50.29 nm with a surface area value of 120.10 m2/ cm3, and the volume mean diameter and Sauter mean diameter were 50.63 nm and 49.96 nm, respectively. Despite the compound found in lemongrass extract, no antimicrobial activity was observed with the extract, while AgNPs exhibited noteworthy dose-dependent antimicrobial activity with inhibition diameters up to 24 mm and minimum inhibitory concentration (MIC) and minimum bactericidal concentration ranging from 2 to 16 and 4–64 µg/mL, respectively. AgNPs also demonstrated significant antibiofilm activity by inhibiting biofilms up to 99% between MIC/2 and 2MIC. Conclusion: The present study suggests that lemongrass is a good candidate for the synthesis of AgNPs with good physicochemical characteristics and having a strong anti-pseudomonas activity. Further research is needed to assess the stability and safety of these AgNPs. Keywords: antibiofilm capacity, antimicrobial activity, green synthesis, lemongrass, Pseudomonas aeruginosa, silver nanoparticles.

Published: April 2024

Az elmúlt évek változásai – köztük a globalizáció, technológiai fejlődés vagy a pandémia – komoly kihívások elé állítják a szervezeteket, melyek megoldásában egyre nagyobb hangsúlyt kapnak a kreatív, innovatív HR-eszközök, melyek egyike a játékosítás, amit számos nemzetközi szervezet gyakorlatában eredményesen alkalmaztak. A szerzők a kutatás során azt vizsgálták, hogy milyen mértékű nyitottság mutatkozik a munkavállalói oldal képviselőiben egy gamifikált kiválasztási eszköz kipróbálására. A szakirodalmi áttekintést követően primer kutatásuk részleteit ismertetik, melyet egy preferenciaértékelő módszerre, a diszkrét választási kísérletre alapozva végeztek el. Az eredmények alapján megállapítható, hogy a válaszadók (n=205) több mint 80%-a nyitott egy gamifikált kiválasztási eszköz kipróbálására. A diszkrét választási modellezés alapján a hagyományosabbnak számító (online böngészés, ismerősök megkeresése) megközelítések azonban preferáltabbnak tekinthetők a válaszadók körében, mint a vizsgált innovatív – videójátékon keresztüli – álláskeresési megoldás. Javaslatként megfogalmazható, hogy jó gyakorlatok bemutatásával a játékosítás népszerűsíthető, mely innovatív megoldást jelenthet a fent említett kihívásokra.

Published: April 2024

A 2006-os ENSZ-egyezmény kimondja, hogy egyenlő jogok, lehetőségek illetik meg a fogyatékossággal élőket. Magyarországon a 2011-es népszámlálás alapján a fogyatékossággal élők közel 73%-a tapasztal akadályozottságot a mindennapi élete során. Egy nemzetközi szintű sportrendezvény hatást gyakorol az adott ország társadalmára, így egy nemzetközi parasportrendezvény felhívhatja a figyelmet a fogyatékossággal élő lakosságra. Lehetőség teremtődik arra, hogy megfelelő tervezéssel, szervezéssel a rendezvény katalizátorként működhessen és jelentősen javuljon a helyzetük. A szakirodalmi áttekintésben a szerzők törekednek a téma alapfogalmainak rendszerezésére. A szekunder kutatás során korábbi nemzetközi parasportrendezvények hatásait elemzik. A primer kutatás felméri a hazai parasport jelenlegi helyzetét. Kutatási kérdésük: mi szükséges ahhoz, hogy Magyarországon egy sikeres nemzetközi parasportrendezvény szervezése valósulhasson meg, mely hosszú távon javíthatja a fogyatékossággal élők helyzetét. A kutatás eredményeként megfogalmaznak egy négyelemű kritériumrendszert, amelyre alapozva valósulhat meg egy sikeres nemzetközi parasportrendezvény. Ezek a következők: akadálymentesítés, hozzáférhetőség, szellemi akadálymentesítés, élsport és szabadidősport differenciált kezelése, finanszírozás.

Published: April 2024

A napjainkban az egyre gyakoribb válsághelyzetek miatt az önkéntes szervezetek szerepe fontosabb, mint valaha. Ahhoz, hogy ezek a szervezetek hatékonyan tudjanak segíteni az arra rászorulóknak, önkéntesekre van szükségük, az önkéntesek megszólításához és toborzásához pedig elengedhetetlen a kommunikációban rejlő potenciál kihasználása. Az önkéntességet mint jelenséget vizsgáló kutatások az egyéni jellemzőket (motiváció, nem, kor, kulturális sajátosságok stb.), az önkéntesség hatásait (pl. szubjektív jóllét és elégedettség), illetve a szervezeti aspektusokat (pszichológiai szerződés, munkavállalói önkéntesség, megbízhatóság és hozzájárulás) helyezték fókuszba. A kommunikáció szerepét is azonosították, elsősorban a toborzási tevékenység és az önkéntességről való kommunikáció témájának vizsgálatával. A tanulmány célja az önkéntes tevékenységgel kapcsolatos eddigi kutatások eredményeinek összegzése integratív szakirodalmi áttekintéssel, és további lehetséges kutatási irányok felvázolása. A kutatási irányok közül a legfontosabb az önkéntességre való hajlandóság komplex vizsgálata, például a toborzási üzenettartalom és a szájreklám moderáló hatásának szempontjából, a tervezett magatartás elméletét alkalmazva.
The Use of Micronized Amniotic Membrane as an Adjunct in Long Bone Nonunion Surgery
Authors: Stewart Christopher
Published: April 2024

Purpose:

Nonunions are difficult to treat and carry a high financial burden. Human amniotic membrane tissue (AM) has been used in multiple orthopedic procedures to augment healing. Due to the complexity of nonunion repair, along with the difficulty with healing, micronized AM may aid in obtaining union during the patients’ nonunion repair surgery.

Methods: A single-center retrospective review at a level II trauma center was performed on consecutive patients 18 years of age or greater that were surgically treated for atrophic long bone (humerus, radius/ulna, femur, tibia) nonunion with adjunctive micronized AM (Clarix Flo®) from January 2020 through May 2022.

Results: A total of 26 patients (14 male, 12 female) aged 52.8 ± 18.8 years (range: 20-95 years) with 29.2 ± 8.0 BMI met the eligibility criteria and were included in the study analysis. All patients who had their nonunion repaired were followed for at least one year (range: 12- 24 months). Twenty-three patients 23/26, healed their nonunion, for overall union rate of 88.5%. The three patients that did not heal had co-morbidities including osteoporosis, Diabetes Mellitus, Ankylosis Spondylitis and Chronic Kidney Disease. There were no complications observed related to the micronized AM.

Conclusion: Micronized AM added at the time of nonunion repair surgery resulted in 88.5% union rate in a diverse population of atrophic long bone nonunions.
Impact of External Reflected Light Injection on

ASE Spectra and Mode Hopping of Laser
Authors: wu yang
Published: April 2024

This paper explores the impact of external reflected light injectionon the Amplified Spontaneous Emission (ASE) spectrum of lasers. When external reflected light enters the laser cavity, the relative intensities of adjacent longitudinal modes change from a smooth transition to a discontinuous variation. This affects the stability of the laser's output power during mode hopping, leading the laser cavity to choose a distant side mode instead of an adjacent mode. The paper analyzes thepossibleoptical paths within the laser cavity and proposes an effective programming algorithm, successfully predicting the ASE spectrum under different external cavity lengths. This enhances the comprehension of the ASE spectrum, offering a laser solution that reduces the mode hopping frequency by half, thereby providing valuable insights for optimizing laser design and enhancing stability in real-world applications.
Refugee Reception in Southern Africa: National and Local Policies in Zambia and South Africa
Authors: Maple Nicholas
Published: April 2024

**A new understanding of state-based refugee reception that reflects the complex dynamics of contemporary refugee arrival.** It is no longer realistic (if it ever was) to understand persons who flee across a border as a homogeneous group whose movement abruptly ends once they arrive in a host state or refugee camp. Through a comparative analysis of the politics surrounding the welcome afforded to refugees, this book offers an original perspective on refugee hosting in Southern Africa. Using the cases of Zambia and South Africa, the book explores why some countries maintain encampment reception policies for refugees, and others use more liberal ‘free settlement’ approaches, whereby refugees are granted freedom of movement and permitted to settle in cities and towns. While state-based reception is frequently framed as one-off moments, such as registration, *Refugee Reception in Southern Africa* examines reception as a complex and ongoing process of negotiations between refugees and state, with reception policies vital in shaping a refugee’s ability to settle and engage with local communities and labour markets. With its new ‘refugee reception’ framework and in-depth case studies full of concrete examples, this book is a significant theoretical and methodological contribution to migration studies more broadly.
Experimental and numerical investigations of multi-layered ship engine room bulkhead insulation thermal performance under fire conditions
Authors: Pham Thanh-Nhut , Le Quoc Tien , Do Quang Thang
Published: April 2024

The thermal insulation layer of the ship’s engine room bulkhead is typically constructed from multiple layers of mineral wool. This layer is designed to keep the temperature on the surface of the bulkhead below 140°C in case of a fire. However, measuring the inner and external temperatures of each wall panel bulkhead type during a fire can be difficult. To address this issue, this study was conducted to evaluate the multilayer heat transfer capability of the bulkhead insulation in the event of an engine room fire. The study used heat transfer theory, experimental models, and numerical analysis to assess nine bulkhead insulation specimens. These specimens were fabricated from three original specimens and included a 10–30 mm air layer (W-75, W-50, and W-25). The results showed that all improved specimens had better thermal insulation than the originals. Among them, the improved specimens derived from the W-25 specimen exhibited the most significant temperature reduction compared to those derived from the W-75 and W-50 specimens. The results demonstrated a slight difference between the three methodologies, indicating a high level of reliability in the research findings.

The study aims to explore how students perceive the use of interactive computer simulations (ICS). The mixed-method approach under a converging design was employed to collect quantitative and qualitative data. A sample of 160 participants were purposively selected. The questionnaire consisted of four sections, including Behavioral Intention to Use, Attitude Toward Usage, Usefulness, and Perceived Ease of Use. The collected data was analyzed in MS Excel. 83 % of participants believed that their learning experience has improved and become easier. Moreover, a significant number of students 79 % expressed high perceptions towards the ease-of-use ICS in the teaching and learning process, and 77 % demonstrated a strong positive attitude towards the usage. Additionally, 76 % had a highly positive perception of their behavioral intention to use ICS in their chemistry learning. However, 39 % of students expressed low perceptions of ease of use of ICSs due to a lack of basic computer skills. In general, the findings show positive significance in students’ perceptions toward the use of ICSs in teaching and learning chemistry. The study recommends that ICSs should be used to supplement chemistry education.
