Eel Management Plan for Kaliningrad (Vistula) Lagoon
Authors: Cheban Kseniia , Khrustalev Evgenij , Vinokurov Yuri
Published: August 2022

In 2007, the European Commission initiated the Eel Recovery Plan (Council Regulation No. 1100/2007) to try to bring the European eel stocks back to more sustainable adult levels and the return of the glass eel. Each EU Member State is required to develop a national eel management plan. These plans aim to achieve a return of silver eels to the spawning population equal to or greater than 40% of the potential biomass that could be obtained in the absence of anthropogenic disturbances related to fishing, water quality or barriers to migration. The advantage of this approach is that it offers a standard basis and allows for the integration of stock status data between EU and non-EU countries.

The purpose of this Plan was to determine for the Vistula Lagoon within the territory of the Kaliningrad region of the Russian Federation:

1. Management objectives based on an assessment of the potential stock of the silver eel in the absence of anthropogenic mortality and high (before 1980) recruitment levels.

2. The current level of the stock of silver eel in relation to the planned indicator (ie assessment of compliance with the planned indicator).

3. Control actions necessary to achieve or maintain this compliance.

4. A set of data needed to support the steps 1-3 above and to demonstrate whether compliance will be achieved in the future, i.e. that the actions defined in the management plan will lead to the recovery of the eel population.
Technology of production of protein feed mixtures for hydrobionts based on cultured worms Eisenia fetida and Dendrobena Veneta using freeze drying technology
Authors: Bugaev Oleg , Leonov Ivan , Klimov Viktor , Khatuntsov Daniil , Ponomarev Andrey
Published: August 2022

The technology being developed for the production of a feed mixture based on the biomass of a cultivated worm is aimed at improving factory feeds by adding an additional volume of protein, thereby increasing the nutritional value of the feed, eliminating the need to buy a specific feed of greater nutritional value, providing the opportunity to supplement feeds less saturated with protein components. Also, the technology being developed is aimed at partial or complete replacement of currently known protein feed components (such as soy meal, meat and bone meal and fish meal).

In the course of the study, a trial production of a protein feed component was carried out, according to the methodologies described in the work, in order to test the proposed technology in practice.
Efficiency of artificial reproduction of whitefish (Coregonus lavaretus L.) of the Curonian Lagoon of the Baltic Sea
Authors: Shibaev Sergey , Shibaev Leonid , Malinovskij Vladislav
Published: August 2022

The paper examines the effectiveness of artificial reproduction of the whitefish of the Baltic Sea, which in autumn comes to spawn in the Curonian Lagoon. Reproduction of whitefish began in 2009 at the experimental fish farm of FSI “Zapbaltrybvod”. The planned volume of reproduction is 150 thousand juveniles of 1-10 g. Due to the technology improvement, the actual volume in recent years has reached 350 thousand pieces. The rate of commercial return of whitefish is unknown. As an indicator of the effectiveness of artificial reproduction, biological parameters of the whitefish spawning stock have been used, which are annually assessed based on the monitoring results. It has been established that over 10 years of operation of the fish-breeding plant, there has been a change in the size and age structure of the population towards rejuvenation, which indicates recruitment increase, possibly as a result of artificial reproduction. At the same time, an increase has been noted in the indices of the number of the spawning stock of whitefish by 10 times and the volume of commercial catch by 4 times. All these can serve as artificial reproduction effectiveness indicators. It is recommended to modify the monitoring system for whitefish during harvesting of its spawners in order to obtain a more complete picture of the state of its population and assess artificial reproduction effectiveness.

Information and Communication Technology (ICT) has become a backbone in educational sector for value reorientation and sustainable development in Nigerian schools. Its role has virtually diffused educational system, forcing technological changes and creating a culture of dependence on technology. The role of ICT in education for teaching and learning has successfully changed the social, economic, political and education environments in Nigeria. Undoubtedly, ICT has enabled the globalised world become greatly interconnected and interdependent and succeeded in breaking the border walls. The use of mobile phones, laptops, tablets, IPads, internet services, software, Artificial Intelligence (AI) and other ICT tools have become the new culture in academic and other institutions. The aim of this paper is to discuss how to manage educational technology for value re-orientation and sustainable national development. It is recommended among other things that government and private individuals alike should try and increase the accessibility of computer hardware and software to the citizens at affordable prices and also that citizens of Nigeria should be educated on the benefits of educational technology for value reorientation and sustainable development.
Kazova’da (Dazimonitis) Yeni Keşfedilen Basamaklı Tünelli Bir Pontos Krallığı Kalesi: Dereköy Kalesi

Published: August 2022

Strabon’un, içinden Iris’in aktığı ve verimli bir ova olarak tanımladığı Dazimonitis bugünkü Kazova’nın Antik Çağ’daki adıydı. Dazimonitis Hellenistik Dönem’in başlarında Pontos Krallığı’nın, bu dönemin sonlarına doğru ise Roma’nın sınırları içerisine dâhil edilse de belirtilen bu tarihi süreçlerde yarı-özerk statüye sahip Komana tapınak devletinin mülküydü. Ancak Dazimonitis’in, Pontos Krallığı ile Roma arasında yaşanan mücadelede bir rolü olduğu da bilinmektedir. Bu bağlamda III. Mithradates-Roma Savaşı sırasında, VI. Mithradates tarafından ovanın sunmuş olduğu erzak tedariki imkânı ortadan kaldırılarak Roma ordusu yıpratılmaya çalışılmıştı. Dazimonitis’in sadece bu amaca hizmet etmediğini, Kazova’nın güneyindeki dağlık kesimde yer alan ve Pazar ilçesini Artova üzerinden Sivas iline bağlayan stratejik bir yol üzerindeki bir tepede konuşlandırılmış ve şimdiye kadar herhangi bir bilimsel çalışmanın konusu olmamış olan Dereköy Kalesi kanıtlamaktadır.

Kazova’nın üzerine kurulu olan Pazar ilçesinde 2019 yılında gerçekleştirdiğimiz arkeolojik yüzey araştırması sırasında inceleme fırsatını bulduğumuz Dereköy’de bulunan ve köyün adıyla anılan kale, basamaklı bir tünele sahip olmasıyla dikkatleri üzerine çekmektedir. Böylece Dazimonitis’te yeni bir Pontos Krallığı Kalesi keşfedilerek bu dönemdeki savunma sisteminin atar damarları olan kaleler ağının şimdiye kadar bilinmeyen bir parçası bölge tarihine kazandırılmıştır. Bu çalışmayla söz konusu kalenin Hellenistik Dönem’deki yeri, önemi ve işlevi açığa çıkartılmaya çalışılacaktır.
Bee Houses as a Rural Construct: Sampling from Konya, Türkiye
Authors: Erkovan Nisa Yılmaz , Özgenel Lale
Published: August 2022

Within the historical and geographical continuity of beekeeping culture, a rural building typology has developed for the storage of hives and use of bees. The bee house structures, also known as apiaries and function as shelters used by bees to produce honey are unique and distinctive components of the rural context. The architecture of these structures can be examined in a typological framework through their tectonic qualities as they differ in terms of material, construction logic, and architectural design. This study addresses the bee house as a rural architectural type and interprets the typological reading by examining the structural construct and logic of this building type through the concepts of “tectonic” and “syntax”. To illustrate the discussion, a group of bee houses identified and documented in the field surveys conducted in rural areas within the borders of Konya province in Turkey are introduced and contextualized; typology is prepared by classifying the documented sample according to construction techniques. For comparison, Antalya examples which set the basis of the typology are briefly mentioned.
Çarlık Rusya’nın Kafkas Hattı’nı İnşası ve Kuzey Kafkasya’da Hâkimiyet Kurma Mücadelesi*
Authors: Çaycıoğlu Serdar Oğuzhan
Published: August 2022

Kafkas Hattı, Çarlık Rusya’nın Kafkasya’da yayılmasında ve uzun süreli bir hâkimiyet kurmasında önemli bir yere sahiptir. Bu çalışmada, tahkim edilmiş yerleşim yerleriyle (stanitsa) birbirine bağlanan hattın yapısı, özellikleri ve bölgedeki Rus hâkimiyeti için sağladığı avantajlar incelenmektedir. Kuban ile Terek boylarında uygulanan Rus Kazaklarının iskânı ve hat üzerinde kurulan kaleler, bölgede oluşturulmak istenilen idari-askerî düzen için oldukça önemlidir. Rusların bu faaliyetleri aslında Osmanlı İmparatorluğu’nun Kırım Hanlığı üzerinden Kuzey Kafkasya ile kurduğu irtibatı koparmaya yönelik adımlardır. Zaten XVI. yüzyılda Rusların Terek’te kurduğu kalelerin Osmanlı ve Rusya arasında diplomatik krize dönüşmesi de buradan kaynaklanmaktadır. Vladikavkaz’dan Tiflis’e kadar uzanan Gürcü Askerî Yolu’nun inşası da Rusların Güney Kafkasya’ya inmelerinde büyük rol oynamıştır. Bu yol aynı zamanda Çarlık Rusya’nın dağlık bölgelerdeki hâkimiyeti sağlamak için itaat altına almak istediği halklar üzerine askerî operasyonlar düzenlediği ana güzergâhtır. Haberleşme ve askerî sevkiyatın yapıldığı bu yolun ve aynı zamanda sınır hattının güvenliği için Kafkasya’nın dağlık bölgelerine çok sayıda sefer düzenlenmiştir. Bu amaçla uzun yıllar hattın komutanlığını yapan General Velyaminov ve Kafkasya Orduları Başkomutanı Baron Rozen’in 1831-1832 yılları arasında düzenlediği seferler de bu makalede incelenmektedir.
PERFUSION LUNG SCINTIGRAPHY IN PATIENTS WITH A PULMONARY HYPERTENSION OF A VARIOUS ETIOLOGY
Authors: Arkhipova O. A. , Martynyuk T. V. , Samoilenko L. E. , Sergienko V. B. , Chazova I. Ye.
Published: August 2022

The pulmonary hypertension is characterized by increase of pulmonary vascular resistance, pressure in a pulmonary artery, remodeling of heart and vessels and the lowest survival of patients. It agrees offered in 2009 the European society of cardiologists to algorithm a ventilation/perfusion scintigraphy takes the central place in differential diagnostics between various forms of a pulmonary hypertension. The scintigraphic picture is well studied at patients with the pulmonary hypertension which has developed owing to the transferred thromboembolism of branches of a pulmonary artery. The distributions of RFP given direct comparison and nature of changes of perfusion depending on a genesis of pulmonary hypertension and gravity of a disease in literature aren't presented. At the same time the knowledge of features of scintigrams can be useful in differential diagnostics and a forecast assessment at patients with a pulmonary hypertension of a various etiology.
Magnetized Oscillatory Double-diffusive Convection
Authors: Sanghi A. , Fraser A. E. , Tian E. W. , Garaud P.
Published: August 2022

We study the properties of oscillatory double-diffusive convection (ODDC) in the presence of a uniform vertical background magnetic field. ODDC takes place in stellar regions that are unstable according to the Schwarzschild criterion and stable according to the Ledoux criterion (sometimes called semiconvective regions), which are often predicted to reside just outside the core of intermediate-mass main-sequence stars. Previous hydrodynamic studies of ODDC have shown that the basic instability saturates into a state of weak wave-like convection, but that a secondary instability can sometimes transform it into a state of layered convection, where layers then rapidly merge and grow until the entire region is fully convective. We find that magnetized ODDC has very similar properties overall, with some important quantitative differences. A linear stability analysis reveals that the fastest-growing modes are unaffected by the field, but that other modes are. Numerically, the magnetic field is seen to influence the saturation of the basic instability, overall reducing the turbulent fluxes of temperature and composition. This in turn affects layer formation, usually delaying it, and occasionally suppressing it entirely for sufficiently strong fields. Further work will be needed, however, to determine the field strength above which layer formation is actually suppressed in stars. Potential observational implications are briefly discussed.
Synchrotron Self-Compton Afterglow Closure Relations and Fermi-LAT-detected Gamma-Ray Bursts
Authors: Fraija N. , Dainotti M. G. , Ugale Sahil , Jyoti Debarpita , Warren Donald C.
Published: August 2022

The Fermi Large Area Telescope (Fermi-LAT) Collaboration reported the Second Gamma-ray Burst Catalog (2FLGC), which comprises a subset of 29 bursts with photon energies above 10 GeV. Although the standard synchrotron forward-shock model has successfully explained the gamma-ray burst (GRB) afterglow observations, energetic photons higher than 10 GeV from these transient events can hardly be described in this scenario. We present the closure relations (CRs) of the synchrotron self-Compton (SSC) afterglow model in the adiabatic and radiative scenario, and when the central engine injects continuous energy into the blast wave to study the evolution of the spectral and temporal indexes of those bursts reported in 2FLGC. We consider the SSC afterglow model evolving in stellar-wind and the interstellar medium (ISM), and the CRs as a function of the radiative parameter, the energy injection index, and the electron spectral index for 1 < p < 2 and 2 ≤ p. We select all GRBs that have been modeled with both a simple or a broken power law in the 2FLGC. We found that the CRs of the SSC model can satisfy a significant fraction of the burst that cannot be interpreted in the synchrotron scenario, even though those that require an intermediate density profile (e.g., GRB 130427A) or an atypical fraction of total energy given to amplify the magnetic field (ε

B
). The value of this parameter in the SSC model ranges (ε

B
≈ 10−5 − 10−4) when the cooling spectral break corresponds to the Fermi-LAT band for typical values of GRB afterglow. The analysis shows that the ISM is preferred for the scenario without energy injection and the stellar-wind medium for an energy injection scenario.

⊙, and we estimate its age as 100 Myr to 1 Gyr based on its stellar activity (via Hα and X-ray emission), kinematics, and spectrophotometric properties. We derive its bulk metallicity as 0.21 ± 0.07 dex using empirical calibrations established by older and higher-gravity M dwarfs and find that this [Fe/H] could be slightly underestimated according to PHOENIX models given COCONUTS-3A’s younger age. The companion, COCONUTS-3B, has a near-infrared spectral type of L6 ± 1 int-g, and we infer physical properties of T

We find that this companion possesses ample condensate clouds in its photosphere (f
sed = 1) with the data–model discrepancies likely due to the models using an older version of the opacity database. Compared to field-age L6 dwarfs, COCONUTS-3B has fainter absolute magnitudes and a 120 K cooler T

COCONUTS-3 likely formed in the same fashion as stellar binaries given the companion-to-host mass ratio of 0.3 and represents a valuable benchmark to quantify the systematics of substellar model atmospheres.
The Dark Matter Halo of M54
Authors: Carlberg Raymond G. , Grillmair Carl J.
Published: August 2022

M54 is a prototype for a globular cluster embedded in a dark matter halo. Gaia Early Data Release 3 photometry and proper motions separate the old, metal-poor stars from the more metal-rich and younger dwarf galaxy stars. The metal-poor stars dominate the inner 50 pc, with a velocity dispersion profile that declines to a minimum around 30 pc then rises back to nearly the central velocity dispersion, as expected for a globular cluster at the center of a cold dark matter (CDM) cosmology dark matter halo. The Jeans equation mass analysis of the three separate stellar populations gives consistent masses that rise approximately linearly with radius to 1 kpc. These data are compatible with an infalling CDM dark matter halo reduced to ≃3 × 108
M
⊙ at the 50 kpc apocenter 2.3 Gyr ago, with a central globular cluster surrounded by the remnant of a dwarf galaxy. Tides gradually remove material beyond 1 kpc but have little effect on the stars and dark matter within 300 pc of the center. M54 appears to be a “transitional” system between globular clusters with and without local dark halos whose evolution within the galaxy depends on the time of accretion and orbital pericenter.
Component of Energy Flow from Supercritical Accretion Disks Around Rotating Stellar Mass Black Holes

Published: August 2022

By performing two-dimensional axisymmetric general relativistic radiation magnetohydrodynamics simulations with spin parameter a* varying from −0.9 to 0.9, we investigate the dependence on the black hole spin of the energy flow from a supercritical accretion disk around a stellar mass black hole. It is found that optically and geometrically thick disks form near the equatorial plane, and a part of the disk matter is launched from the disk surface in all models. The gas ejection is mainly driven by the radiative force, but magnetic force cannot be neglected when ∣a*∣ is large. The energy outflow efficiency (total luminosity normalized by

Edd is the Eddington luminosity). Furthermore, although the energy is mainly released by radiation when a* ∼ 0, the Poynting power increases with ∣a*∣ and exceeds the radiative luminosity for models with a* ≥ 0.5 and a* ≤ −0.7. The faster the black hole rotates, the higher the power ratio of the kinetic luminosity to the isotropic luminosity tends to be. This implies that objects with a high (low) power ratio may have rapidly (slowly) rotating black holes. Among ultraluminous X-ray sources, IC342 X-1, is a candidate with a rapidly rotating black hole.

Reionization in the Light of Dark Stars
Authors: Gondolo Paolo , Sandick Pearl , Shams Es Haghi Barmak , Visbal Eli
Published: August 2022

We investigate the effect of dark stars (DSs) on the reionization history of the universe, and the interplay between them and feedback due to Lyman–Werner (LW) radiation in reducing the cosmic microwave background (CMB) optical depth to a value within the τ = 0.054 ± 0.007 range measured by Planck. We use a semianalytic approach to evaluate reionization histories and CMB optical depths, which includes Population II stars in atomic cooling halos and Population III stars in minihalos with LW feedback, preceded by a DS phase. We show that while LW feedback by itself can reduce the integrated optical depth to the last scattering surface to ∼0.05 only if the Population III star formation efficiency is less than ∼0.2%, the inclusion of a population of DSs can naturally lead to the measured CMB optical depth for much larger Population III star formation efficiencies ≳1%.

Published: August 2022

BACKGROUND: Finding the optimum vascular grafts (VG) to replace damaged blood arteries in cardiac surgery is still a work in progress. To be employed, a tissue-engineered VG (TEVG) must have the appropriate biological and mechanical qualities. Decellularized arteries may be a better TEVG than synthetic grafts because of their natural three-dimensional architecture.

AIM: The goal of this study was to compare different concentrations and times of sodium dodecyl sulfate (SDS) to decellularize tissue to find the best decellularized VG.

METHODS: In all decellularized scaffolds, which are 1% SDS-2 weeks group, hematoxylin and eosin and Masson’s trichrome staining exhibited looser collagen networks and fewer nuclei.

RESULTS: The orientation of collagen fibers was identical to native vascular scaffolds. Collagen I deposition was seen in the immunohistochemistry assay. A tensile strength test revealed that the decellularized scaffold (0.5% SDS for 4 weeks and 0.5% SDS for 2 weeks) had exceeded the native arteries’ maximal strength. In comparison to 1% SDS in 4 weeks treated groups, scanning electron microscopy following decellularization revealed no endothelial cells on the inner side of 1% SDS in 2 weeks group with minimum extracellular matrix damage. The endothelial cells remained marginally visible on the inner side of all 0.5% SDS treated groups. The 3-(4,5-dimethylthiazol-2yl)2,5-diphenyltetrazolium bromide test was used to determine the cytotoxicity of the decellularized scaffolds.

CONCLUSION: This study reveals that exposing a bovine mesenteric artery to 1% SDS for 2 weeks is an excellent procedure for extracting the most acellular VG, potentially serving as a biological scaffold for TEVGs.

Published: August 2022

Coronary heart disease (CHD) contributes to decreased health-related quality of life (HRQOL). This review article investigates the factors that can affect the HRQOL in CHD patients. A literature search from PubMed and EBSCO databases was performed until March 2021 with predetermined keywords. The review of 15 included articles showed that many factors that can affect the HRQOL by using EQ-5D instrument in CHD patients, such as education, gender, comorbidity, percutaneous coronary intervention (PCI)/coronary artery bypass graft (CABG) intervention, patient-physician interaction, obesity, physical activity, numbers of medication, smoking, self-efficacy, social/family life, alcohol drinking, income, employment, and behavioral risk factor profile. The top three factors associated with HRQOL in CHD patients were education, gender, and comorbidity. Therefore, we should pay more attention to CHD patients with lower education levels, females, and comorbidity.

Parallèlement, va se développer un nouveau langage, celui du transmédia, qui entraînera la disparition du multimédia vieillissant et annoncera l’apparition de nouveaux formats numériques en remplacement des CD et DVD, appelés à disparaître. Tout ceci va se passer sur une période courte au cours de laquelle s’enchaîneront les défis, période qui permettra au secteur éditorial de prendre un nouveau départ.

Les notions de perception et de verbe de perception sont-elles des notions linguistiques ?
Authors: Anscombre Jean-Claude
Published: August 2022

L’homme a un certain accès au monde par le biais de ses perceptions, surtout la vue, qui le renseignent de façon partielle et partiale sur les états de ce monde ou d’une partie de celui-ci. Par ailleurs, l’homme dispose grâce à la langue d’une représentation linguistique du monde. Dans cette représentation, les percepts issus de sensorielles – la vue, l’ouïe, le goût, le tact et l’odorat – sont conçues comme des perceptions directes , c.-à-d. comme directement appréhendées. Si l’on cherche, inversement, quelles autres connaissances ont en langue le statut de perception directe, les propriétés linguistiques montrent que les savoirs communs en font partie. On comprend alors pourquoi le verbe voir , qui est au centre de cette étude, désigne très généralement l’acquisition de certaines connaissances, et pas seulement au moyen de la vue. Ce qui est cohérent avec l’origine de voir , c.-à-d. *weid ‹acquérir le savoir›.

Intérêt de la surveillance des voies d’abord par monitorage des pressions de perfusion en néonatalogie
Authors: Guy B. , Pons de Vincent J.F.
Published: August 2022

L’occlusion des cathéters présente des risques exacerbés en néonatalogie. Un moyen efficace de prévenir ces occlusions a été apporté par la surveillance de la pression de perfusion, notamment à l’aide d’une pompe volumétrique munie d’un secteur de pression. Cette technique permet deux surveillances : affichage permanent de la pression de perfusion et réglage journalier d’une alarme de surpression. Les pressions de perfusion sont stables autour de +/– 30 cm H 2 O d’une pression moyenne. Ainsi, toute élévation au-dessus de cet écart est suspecte. La surveillance régulière de la pression qui a été adoptée depuis par le service permet de diagnostiquer toute surpression anormale, due par exemple à une occlusion. L’alarme de surpression est réglée optimalement à 30 cm H 2 O au-dessus de la pression de perfusion. Son efficacité porte sur la rapidité pour déceler une amorce d’occlusion et ainsi que la détection précoce des diffusions tissulaires.
Vous avez dit : « Protocoles » ? Les protocoles dans la pratique infirmière
Authors: Bizet Marie-Pierre
Published: August 2022

Le terme protocole n’est pas réservé à la profession infirmière, au fil des siècles son sens a évolué. Aujourd’hui, utilisé de façon habituelle par les professionnels infirmiers, ce terme possède pourtant de nombreux sens. Après avoir tenté de les lister et de les expliciter, l’intérêt des protocoles dans la pratique infirmière a été dégagée, et une stratégie d’implantation succinctement établie dans une unité de soins.
Procédures et processus dans les soins infirmiers
Authors: Nolin Michèle
Published: August 2022

Le dispositif est conçu en référence au modèle théorique de l’engagement en psychologie sociale. Il vise dans un premier temps à faire accepter à des infirmières un travail de réflexion sur la prévention des infections nosocomiales exogènes puis à leur faire analyser des fautes d’asepsie présentées sur vidéofilm, et enfin à s’auto-évaluer sur une courte période. L’ hypothèse pose que si le scénario ne permet pas d’attribuer ces fautes à des causes externes non maîtrisables par les professionnels nous créerions un contexte favorable à l’autorégulation des conduites aseptiques lorsqu’ils se trouveraient en situation d’auto-évaluation. Nos résultats ont permis de mettre en évidence : une augmentation significative du lavage des mains sur les 3 mois qui ont suivi l’expérience, une élévation significative d’explications « personologiques » au fur et à mesure du déroulement du dispositif attestant d’une élévation de l’activité d’internalisation quant à l’explication des fautes d’asepsie. En conclusion nous admettons que ce travail ouvre des perspectives en terme d’analyse didactique des situations de travail.
Clinical Characteristics of Patients With Delirium Consulted During the First Year of the COVID-19 Pandemic, and the Role of Monocyte to Lymphocyte Ratio in Survival of COVID-19-Positive Patients With Delirium
Authors: Küçükkarapınar Melike , Ünal Berfu , Candansayar Selçuk
Published: August 2022

The development of delirium can lead to severe and significant consequences for the patient. The primary aim of the study was to identify potential differences in clinical characteristics and medical management between elderly hospitalized patients with delirium and with and without coronavirus disease 2019 (COVID-19). A secondary aim was to report the short-term outcomes and possible predictors of outcomes of both patient groups. A retrospective study was conducted. Patients' records were screened for delirium. Clinical and laboratory data were collected, including baseline inflammatory markers. No significant difference was found between the patients with and the patients without COVID-19 regarding clinical characteristics and the dose of antipsychotic medication. COVID-19-positive delirium was not different from COVID-19-negative delirium in terms of length of hospital stay, intensive care, and antipsychotic needs. Monocyte to lymphocyte ratio (MLR) may be a predictor of survival in patients with COVID-19 and delirium.

What College Mental Health Systems Should Prepare Now for Campus Reopening After COVID-19 Vaccinations
Authors: Yoon Sunkyung , Pinder-Amaker Stephanie L.
Published: August 2022

College students faced many challenges due to the coronavirus disease 2019 (COVID-19) pandemic that are unique to them (eg, sudden relocation, interruption in their education and transition to virtual learning, and having to find a mental health provider licensed in their home state when returning home for school closure) and adjunct to challenges faced by the general population (eg, economic strains, racial discrimination, health disparities, and sense of social isolation). Previous studies consistently reported increased stress, mood, and anxiety symptoms and even suicidal ideation among college students since the COVID-19 outbreak. Anecdotally, many students have also shared concerns and anxiety due to returning to normal college life. To better prepare for potential future disruptions and/or other similar challenges, schools need to consider proactive steps for supporting student mental health in their transition not only to virtual learning but also to having them back on campus.

Comparative Effectiveness of Nonoperative Versus Operative Treatment of Completely Displaced Clavicle Shaft Fractures Among Children
Authors: Ames Tyler D. , Mehlman Charles T. , Toy Robert , Parikh Shital N.
Published: August 2022

The goal of this study was to compare outcomes among children treated nonoperatively vs operatively for completely displaced clavicle fractures. This was a retrospective cohort study of nonoperative vs operative treatment of completely displaced clavicle fractures sustained between 2006 and 2015 among pediatric patients. Data were collected on patient demographics, fracture characteristics, time to return to full activities, treatment complications, and patient-reported outcome measures. Fifty-five patients were identified in the nonoperative group, with a mean age of 11.6 years (range, 8–14 years). The operative group contained 55 patients, with a mean age of 14.3 years (range, 9–17 years). All fractures healed, with a mean time to return to full activities of 90.4 days in the nonoperative group and 89.7 days in the operative group (
P
=.941). Twelve (22%) nonoperative patients sustained a refracture of their clavicle compared with 4 patients in the operative group (
P
=.031). Fifteen patients (27%) in the operative group required a second surgery for removal of surgical implants. On the shortened form of the Disabilities of the Arm, Shoulder and Hand (QuickDASH) survey, 17 of the 22 nonoperative patients reported a score of zero (indicating no disability) (range, 0–7) vs 22 of 25 in the operative group (range, 0–9) (
P
=.329). Patients treated nonoperatively had a 22% rate of refracture, whereas patients treated operatively had a 27% rate of undergoing a second surgery for removal of surgical implants. These data can aid in the shared decision-making process with patients and families when deciding on treatment for displaced pediatric clavicle fractures. [

Three-Year Outcomes of Under-flap Stromal Bed CXL for Early Post-LASIK Ectasia
Authors: Wallerstein Avi , Gauvin Mathieu , Rocha Guillermo , Sison Ronald , Korban Salim , Cohen Mark
Published: August 2022

PURPOSE:

To investigate the 36-month clinical outcomes of under-flap stromal bed CXL (ufCXL) and report on its ability to stabilize post-laser in situ keratomileusis (LASIK) ectasia.

METHODS:

This case series included 20 eyes with diagnosed early post-LASIK ectasia treated with ufCXL. Inclusion criteria were early, mild post-LASIK ectasia, defined as new-onset postoperative manifest refraction cylinder of 1.50 diopters (D) or less, with new topographic inferior steepening consistent with ectasia, uncorrected distance visual acuity of 20/40 or better, and corrected distance visual acuity of 20/25 or better. The existing LASIK flap was lifted, 0.25% isotonic riboflavin was applied directly to the stromal bed, the flap was repositioned, and 18 mW/cm
2
ultraviolet light was applied for 5 minutes to the corneal flap surface. Post-ufCXL ophthalmic data were compared to pre-ufCXL baseline measurements.

RESULTS:

Visual outcomes were maintained pre-ufCXL to 36 months post-ufCXL, with preserved safety index (
P
= .6545), efficacy index (
P
= .4980), spherical equivalent accuracy (
P
= .1536), defocus equivalent accuracy (
P
= .1032), central corneal thickness (
P
= .5196), and corneal irregularity indices at 3 mm (
P
= .8548) and 5 mm (
P
= .3399). Refractive astigmatism significantly decreased from 0.83 to 0.55 D pre-ufCXL to post-ufCXL (
P
= .0439), as did maximum keratometry from 42.40 to 42.00 D pre-ufCXL to post-ufCXL (
P
= .0420). The ufCXL demarcation line depth was 336 ± 21 µm post-ufCXL, with normal endothelial cell density (2,574 ± 203 cells/mm
2
). Only 1 of 20 eyes showed evidence of progression of 1.00 D in maximum keratometry.

CONCLUSIONS:

The ufCXL procedure shows promise in stabilizing early post-LASIK ectasia. Visual function, refractive astigmatism, maximum keratometry, and corneal irregularity indices were statistically maintained at 36 months postoperatively.

Existence of solutions for multi-point nonlinear differential system equations of fractional orders with integral boundary conditions
Authors: Al-Shbeil Isra , Benali Abdelkader , Bouzid Houari , Aloraini Najla
Published: August 2022

In this work, we study existence and uniqueness of solutions for multi-point boundary value problemS of nonlinear fractional differential equations with two fractional derivatives. By using a variety of fixed point theorems, such as Banach's fixed point theorem, Leray-Schauder's nonlinear alternative and Leray-Schauder's degree theory, the existence of solutions is obtained. At the end, some illustrative examples are discussed.
A mitologia e a psicanálise do jogo em “Lady Lazarus”
Authors: Da Silva Mariana Soletti
Published: August 2022

O presente trabalho busca referências míticas no que tange ao fogo na poesia de Sylvia Plath, sobretudo em seu poema "Lady Lazarus" (2007). Para tal, valemo-nos das considerações sobre o mito de Durand (1996, 2010) e Eliade (2016). Utilizaremos os escritos de Gaston Bachelard (1994), além de abordarmos questões psicoanalíticas do poema de Plath de acordo com Ana Cecília Carvalho (2003). Buscar-se-á inferir como o fogo trabalha no (e com) o sujeito poético a fim de dissecar todos os estratos poéticos possíveis. Enquanto resultado, entendemos que o sujeito poético se distorce, por meio da linguagem, para torná-lo ilegível ao patriarcado e seus processos. Assim, consegue sobreviver em um ambiente hostil.

Published: August 2022

A leitura sempre foi uma importante ferramenta para auxiliar os indivíduos em qualquer circunstância, desde a obter conhecimentos e informações como também a superar suas próprias crises. Por perceber o isolamento social imposto pela pandemia do novo coronavírus como sendo um período de crise, buscamos averiguar que lugar ocupa a leitura, nos dias de um grupo de estudantes do curso de Licenciatura em Letras – Português e Inglês do Instituto Federal de Educação, Ciência e Tecnologia do Rio Grande do Sul (IFRS), Campus Feliz que aceitaram participar da pesquisa respondendo sobre seus hábitos de leitura durante a suspensão do calendário acadêmico da instituição em 2020. Os dados levantados a partir da pesquisa quali-quantitativa foram cruzados com teorias sobre a leitura e a experiência, principalmente dos autores Michèle Petit e Jorge Larrosa. Como resultado, percebeu-se que os participantes buscaram na leitura e na escrita a possibilidade de auxiliá-los na superação da crise.
Framework for Recruiting Underrepresented and Racially-Minoritized STEM Teacher Candidates
Authors: Burnett Camille S.
Published: August 2022

The purpose of this chapter is to develop a theoretical framework for recruiting underrepresented and racially minoritized (URM) STEM students in order to increase the number of URM STEM teachers. Three possible sources (high schools, community colleges, and four-year institutions) from which to recruit potential URM STEM teachers will be discussed, considering some of the advantages and disadvantages of each. Various career theories will be presented in terms of their applicability to URM STEM teachers. Relevant data and findings from studies that investigated URM students majoring in STEM and STEM teaching will be highlighted. Finally, a recruitment framework that integrates all ideas explored—sources of potential URM STEM teachers, career theory, and data and research on URM students in STEM and STEM teaching—as a means for increasing the number of URM STEM teachers will be proposed.
Upskilling Liberal Education
Authors: Bazemore Alisha
Published: August 2022

The employability of liberal arts education is a concern in a specialized labor market. As a result, there has been much-debated interest in determining the value of a liberal arts degree. Globally, there has been a greater demand for knowledge in science, technology, engineering, and mathematics, or STEM-related fields. Consequently, a liberal arts education's significance has left public opinion to contemplate its value and existence. This qualitative instrumental case study used the National Association of Colleges and Employers (NACE) Career Readiness Competencies as the theoretical framework to identify the qualities, skills, and role liberal arts students at an HBCU contributed to a User Experience/User Interface (UX/UI) design course. The study utilized four methods of data collection and three themes linked to the NACE Competencies that supported the skills of liberal arts students in a UX/UI design course: oral and written communication, teamwork and collaboration, and global and intercultural fluency.
