Feedback and PT Symmetry in a class of Active LCR Circuits
Authors: Mayosky Miguel , Veiga Alejandro , Canal Carlos García , Fanchiotti Huner
Published: April 2023

Systems with non-Hermitian Hamiltonians, especially those exhibiting
parity-time ( PT ) symmetry, are of particular interest as they can
describe physical open systems with balanced loss into and gain from the
environment. In this context, the study of eigenvalue locations and the
corresponding phase transitions as a function of the degree of
non-Hermiticity γ is accomplished hereby using feedback theory.
This approach provides insight about the behavior of these systems and
allows generalization of the results for higher-order ones. The proposed
ideas are analyzed in detail for a class of coupled resonant circuit
chains.

Published: April 2023

The fungal species in Colletotrichum genus are important pathogens of
black pepper (Piper nigrum) to cause dieback of leaves and branches. The
black pepper anthracnose has been observed frequently in Hainan, which
is the main production area of black pepper in China. Thirty-six
isolates from diseased leaves were collected through different fields
located in six main production areas of Hainan. Twenty-three isolates
were found related to black pepper anthracnose and were identified as
Colletotrichum spp. through morphological characteristics and ITS
information via BLAST search. All isolates collected in this study
belonged to Colletotrichumgloeosporioides complex. Six genes including
ITS, TUB2, CHS-1, ACT, GAPDH and ApMat were amplified and sequenced. C.
siamense,C. fructicola, C. arecicola, and C. kahawae were identified as
the main pathogens based on the multi- gene phylogenetic analysis and
morphological characters. This is the first report of these four
isolates associated with black pepper anthracnose in Hainan, China.

Published: April 2023

Phase change materials (PCMs) have gained significant attention as
thermal energy storage materials for reducing dependence on fossil
fuels. However, the leakage caused by long-term molecular motion has
become a bottleneck for the further advances of energy storage density
and application value. Herein, a novel PCM composite with good shape
stability, thermal conductivity and photothermal conversion capability
was designed. Given the synergistic or hybridization effect between
metal-organic frameworks (MOFs) and expanded graphite (EG) components
offered the composite unique capabilities, even with the merits of both.
The combination of ZIF-67 and EG in a hybrid structure can effectively
prevent particle agglomeration, while simultaneously providing a high
specific surface area and pore volume for the adsorption of paraffin
wax. Compared to pristine unsupported PCMs, the as-obtained PCM
composite possesses a 3-fold enhancement in thermal conductivity,
95.56% photothermal conversion efficiency and excellent shape
stability. It demonstrates the potential of MOFs-enhanced PCM composites
for thermal energy storage and highlight the importance of synergistic
or hybridization strategies in the development of advanced materials for
sustainable energy applications.
Citizen Science for the Study of Birds in Distinct Biomes: Diet of the Rufous-Tailed Jacamar (Galbula ruficauda) (Aves, Galbulidae) in Brazil
Authors: Costa Filipe Mateus de Oliveira
Published: April 2023

Data obtained by citizen scientists have been used by researchers to study the natural history of tropical birds in several countries. For example, this approach has been increasing the knowledge about their feeding ecology, as many photographs show birds holding prey with their foot and/or bill. Due to this, the diet of numerous bird species can be examined with citizen science data. The Rufous-tailed Jacamar (Galbula ruficauda) is a forest bird species widely distributed throughout the Neotropics, and its diet was scarcely quantified in a few localities. This study aimed to investigate the diet of the Rufous-tailed Jacamar in three Brazilian biomes: the Caatinga, the Cerrado and the Atlantic Forest. Searches for photographs with evidence of feeding activities were done in February 2021 in the WikiAves and eBird databases, the major citizen science projects regarding birds found in Brazil. For each selected record, the captured prey was tentatively identified to the taxonomic Order level, and the date of obtention was classified as part of dry or rainy periods. The chi-square test was used to compare the numbers of prey of distinct insect orders in different periods and biomes. A total of 283 feeding records were obtained by citizen scientists in the Caatinga (12%) and surrounding portions of the Cerrado (45%) and the Atlantic Forest (43%). Captured prey comprised seven insect orders, and 15% of them could not be identified. In the Cerrado, the most numerous prey in its diet were those of the orders Lepidoptera and Odonata, followed by Hymenoptera and Hemiptera, in both the dry and rainy periods. On the other hand, substantial seasonal variation was observed in the Atlantic Forest. Records with Lepidoptera were more numerous than those with other insects in the dry period, while Hymenoptera had more records than other orders in the rainy period. In the Caatinga, prey with more records were those of the orders Odonata, Lepidoptera and Hymenoptera. This study suggests that photographic records available in citizen science databases, such as WikiAves and eBird, can be used to improve our knowledge about the diet of birds found in the Neotropics.

Published: April 2023

The issue of nationalism which is starting to fade among the younger generation is caused by the negative impact of globalization. Learning history is one of the solutions to revitalize the values of nationalism. This study aims to analyze the process of instilling nationalist values in history learning, the obstacles encountered when instilling nationalist values in history learning, and the efforts made in overcoming the obstacles faced by teachers when instilling nationalist values in history learning. Qualitative type research with case studies. The research subjects were madrasa heads, history teachers, and students of class XI IPS. Data collection techniques: observation, interviews, documentation. Data analysis techniques use the Miles & Huberman model. The results of the study show that the process of instilling nationalist values in history learning is through planning, implementing, and evaluating. The obstacles experienced were students' different backgrounds, difficulties in controlling internet use, mass media reporting, and the absence of a history laboratory. Efforts made by the teacher, namely making himself a role model and motivator, holding an agenda for mandatory visits to historical sites, participating in every national holiday commemoration event. The conclusion of instilling the values of nationalism in history learning can be seen from the cognitive, affective, psychomotor aspects of students.

Authors: Nanang  , Rahmawati Willy Aisyah Taufik
Published: April 2023

In learning mathematics, problem-solving skills are very important. Problem-solving skills will help the person succeed in everyday life. This study aims to analyze the increase in mathematical problem-solving abilities (KPMM) of students whose learning uses the Think-Pair-Share (TPS) cooperative strategy. This research is a class action research that consists of three cycles. The subjects in this study were students of class VIII-A, consisting of 34 students. The instrument used is a mathematical problem-solving ability test (KPMM). Data analysis was carried out with an increased test (normalized gain), learning completeness, and the average level of mastery. Based on the KPMM test results, information was obtained that there were differences in classical learning mastery in aspects of mathematical problem-solving ability in cycles I, II, and III. These findings are supported by the number of students who complete each cycle. For KKM 65, in cycle I, the number of students who completed was 13 students (38.24% of 34 students). In cycle II the number of students who completed was 23 students (67.65% of 34 students), and in cycle III, the number of students who completed there was 28 students (82.35% of 34 students). It can be concluded that TPS learning using students working on worksheets in groups and being guided by the teacher on changing word problems into a mathematical model can increase the KPMM of students with high criteria. The number of students who complete cycle III is more than those who complete cycles I and II.

A Study into the Relationship Between Whistleblowing, Organizational Commitment and Personal Ethical Values: Hirschman’s Exit, Voice and Loyalty in Tourism
Authors: Güven Selda , Şahin Bayram
Published: April 2023

Presently, unethical practices are a major concern in almost every sector. Among these industries is tourism. Requiring large expenditure of labor in particular is one of the causes underlying frequently observed unethical practices. The efforts to prevent such issues are of the utmost value for the sector’s long range sustainability, productivity, and economic contributions. The aim of this study is to discuss the results of the tourism employees with ethical values and high organizational commitment to disclose or not to disclose unethical practices in the enterprise within the framework of Hirschman's Exit, Voice and Loyalty theory and to enhance the understanding the consequences of whistleblowing. Under normal circumstances, an employee with serious ethical concerns and strong organizational commitment is expected not to remain silent about any unethical behavior. However, individuals are not frequently taken actions. From time to time, an employee may choose to take no action and ignore unethical behaviors. They may think that these misconducts will disappear or leave the organization in the belief that nothing in the organization will change nor will be as it should be. In this sense, in the study, the relationship between whistleblowing, personal ethical values and organizational commitment has been conceptually discussed and evaluated in terms of the tourism industry within the framework of Hirschman's Theory.

Published: April 2023

Hibiscus is a widely used plant, which has been proven to have numerous positive effects on human health, such as lowering blood pressure, maintaining optimal blood cholesterol levels, liver protection, prevention of oxidative stress, etc. In this study, the content of polyphenols, flavonoids and antioxidant capacity of aqueous, ethanolic and hydroethanolic (50/50 v/v) hibiscus extracts, prepared by maceration and ultrasonic extraction, was analyzed. Analysis of antioxidant activity was performed in vitro, using FRAP and DPPH methods. The results showed that the mixture of water and ethanol had a significantly higher effect of extraction of bioactive components from hibiscus than the remaining two solvents. The lowest content of polyphenols and flavonoids, and thus the weakest antioxidant activity was recorded in extracts prepared in absolute ethanol. By comparing the efficiency of the techniques used, maceration proved to be slightly more efficient in the case of aqueous and hydroethanol extracts, while higher polyphenol content and higher antioxidant activity were observed in ethanolic extracts prepared by ultrasonic extraction.

Published: April 2023

Background: COVID-19-induced hyponatremia is reportedly associated with pulmonary dysfunction, but mostly among Caucasians. Hence, the current study evaluated sodium status and its correlation with indices of pulmonary dysfunctions among Nigerians of Negroid race.

Methods: This was a retrospectively-designed observational study. Data, all obtained at presentation, were acquired from medical records of 480 RT-PCR-confirmed COVID-19 patients managed at a COVID-19-designated treatment facility in Port Harcourt, Southern Nigeria. Analysis of acquired data was done by COVID-19 clinical grades and sodium status using descriptive and inferential statistics.

Results: At presentation, hyponatremia and hypernatremia were observed in 47.7% and 1.0% of the entire studied cohorts (n=480), respectively. Both disorders (hyponatremia/hypernatremia) were mostly observed among the moderate, severe, and critical cases. Most hyponatremic cases (n=154;67.2%) and the entire hypernatremic cases (n=5;100%) were of mild grades. Hyponatremics had higher proportions of fever, breathlessness, confusion, and a higher burden of inflammatory markers which increased with worsening hyponatremic grade. Etiologically, hyponatremia was mostly associated with the syndrome of inappropriate anti-diuretic hormone secretion (SIADH) (n=132;56.7%). Among the hyponatremics, an inverse correlation existed between sodium and respiratory rate (RR), while a correlation existed between sodium and oxygen saturation (SpO2). Compared to mild hyponatremics, the moderate/severe hyponatremics had a greater risk of having RR>30 and SpO2 <95%. 

Conclusion: Hyponatremia, mostly of mild grade, was common among the studied COVID-19 patients and was associated with indices of pulmonary dysfunctions, including disease severity, inflammatory markers, and SIADH. Hence, hyponatremia should be utilized to triage COVID-19 patients at presentation. However, further studies are recommended to verify these findings.
Canonical Supervision of Rural Communities in Early Byzantium
Authors:   Babeș-Bolyai University, Perșa Răzvan
Published: April 2023

The author attempts in this study to analyse the canonical texts of the Orthodox Church in order to identify certain canonical institutions used by the Church for its pastorship and mission in rural communities and how rural parishes were canonically supervised. To Christianise villages, the Byzantine Church manifested a certain canonical creativity, creating the institution of chorepiscopate responsible for rural ecclesial life and the care for the poor in rural communities. The author emphasizes the full episcopal status of the chorbishops. At the end of the fourth century, the canonical texts limit the canonical privileges of chorbishops even for their rural jurisdiction, prohibiting not just the ordination for the village but the right to ordain priests and deacons for rural communities. Simultaneously with the development of the office of chorbishops, the rank of periodeutai also appeared. These priests resided in the city and were sent by the urban bishop to visit the rural communities as well. They were supervisors of rural communities under the authority of the urban bishop and they can be considered an important link between urban and rural communities, but as well an instrument of exercising episcopal power and control in rural parishes that were previous dominated by the figure of chorbishops.
Kanonische Aspekte über die Pastoration der Familie
Authors:   Lucian Blaga University, Sibiu, Marga Irimie
Published: April 2023

The author of the paper „Canonical Aspects regarding the Pastorship of the Family” starts from the fact the man and the woman, in their perfection, cannot be understood alone, but only “together”. The family emerged from this constitutive “being together” as the primary and inalienable realization of communion. The “little church”, i.e. the family, is also founded on the descent of the Holy Spirit through the sacrament of marriage, which can be called “the little Pentecost” in the “ecclesia minor”. We confess that the Church is one, holy, catholic and apostolic. This is how we understand the little church, the family, as a divine gift that cannot be negotiated. The author emphasises that the Orthodox Church teaches that marriage is an indissoluble sacrament. The indissolubility of marriage is practically not a fact already realized through the sacrament, but a quality that is preserved and fulfilled throughout life. Divorce is a sin and a tragedy. Divorce belongs to our existence, so it cannot be ignored and, unfortunately, cannot be forbidden. Divorce does not abolish the indissolubility of marriage, it abandons it. The author underlines that the Orthodox Church does not accept divorce, because she cannot accept the sin, but she tolerates and recognizes divorce as a painful, indisputable reality. According to the principle of oikonomia, the Church has to choose between two undesirable situations: either to reject the divorced as a great sin or to tolerate the divorced and give a new chance. The author has attempted to show that the Church chooses the lesser evil from these two.

Authors: Araque-Melo Andrés Eduardo
Published: April 2023

Introducción: La artritis séptica es considerada una emergencia en ortopedia, es definida como el proceso inflamatorio desproporcionado desencadenado por la colonización de algún microorganismo en el espacio articular, ocasionando cambios fisiopatológicos que degradan el cartílago ocasionando aumento de la morbimortalidad, prolongación de la estancia hospitalaria, secuelas irreversibles, así como incremento de los costos para el sistema de salud, por tal razón es de vital importancia que el médico general quien tiene el primer contacto con el paciente pueda reconocer las manifestaciones, e instaure tratamiento para evitar complicaciones y secuelas del paciente. Objetivo: Identificar los aspectos importantes de la artritis séptica y proporcionar al lector información relevante de forma práctica y concreta para su actuar medico diario.   Método: Se realizó la búsqueda de artículos originales en bases de datos empleando términos MeSH  y DeCS, consulta de textos guía,  con una temporalidad de búsqueda de 2010 a 2022. Resultados: Se ven afectados con mayor frecuencia pacientes en extremos de edad, como pacientes mayores de 60 años y menores de 20 años, siendo la rodilla la principal articulación afectada. La fiebre no es un criterio necesario para el diagnóstico de artritis séptica y el principal factor de riesgo es la enfermedad articular previa. Conclusiones: El análisis del líquido sinovial y la tinción Gram junto al cultivo permiten hacer diagnóstico. El tratamiento antibiótico empírico es guiado por los factores de riesgo del paciente y posteriormente por los resultados del cultivo.
Reflexiones en torno al uso del lenguaje durante el proceso de duelo
Authors: Tovar Hernández Beatriz
Published: April 2023

RESUMEN

El proceso de duelo ante la pérdida de un ser querido es un fenómeno complejo. Diversas teorizaciones se han propuesto para explicarlo. Para entenderlas es necesario situarse por encima de la sistematicidad, del orden lógico pre-establecido por la razón. No hacerlo puede simplificar la comprensión de las vivencias de los dolientes, quienes han perdido a un ser querido. Este  artículo propone revisar la teoría del duelo de Elisabeth Kübler-Ross apoyándose en la concepción del lenguaje de Ludwig Wittgenstein. La conjunción tanatología y filosofía permitirá una comprensión profunda de la complejidad entrañada en el dolor ante la muerte de quien se
The «One over Many» Argument for Propositions
Authors: Withrington Esteban
Published: April 2023

The meanings of utterances and thoughts are commonly regarded in philosophical semantics as abstract objects, called «propositions», which account for how different utterances and thoughts can be synonymous and which constitute the primary truth-bearers. I argue that meanings are instead natural properties that play causal roles in the world, that the kind of «One over Many» thinking underlying the characterization of shared meanings as abstract objects is misguided and that utterances and thoughts having truth-values in virtue of their meanings does not entail that meanings themselves are truth-bearers.
Filantropía y dignidad humana
Authors: Cincunegui de la Vega Juan Manuel
Published: April 2023

En este artículo analizamos los límites intrínsecos de nociones como la «dignidad humana» y otros análogos interculturales a la luz de la asimetría ineludible que imponen las reglas inherentes de inclusión, exclusión y jerarquía de todo lenguaje. En este marco, analizamos la excepcionalidad que supone la dignidad humana para el concepto mismo de los derechos humanos. Sobre esa base, sostenemos que es imperativo mantener diferenciados los privilegios que reconocemos a los animales humanos, de los derechos que reconocemos a otros animales no humanos, sin que ello implique argumentar en desmedro de estos últimos.  Finalmente, en el marco del análisis epistemológico y lingüístico, reconocemos el carácter paradójico e ineludible de los derechos humanos, que impone «violentamente» un orden de sentido que, en última instancia, parecen fundarse en la exclusiva voluntad del legislador.
Computational Analysis of Soret and Dufour Effects on Nanofluid Flow Through a Stenosed Artery in the Presence of Temperature-Dependent Viscosity
Authors: Mishra Nidhish K.
Published: April 2023

In this study, the Soret and Dufour effects in a composite stenosed artery were combined with an analysis of the effect of varying viscosity on copper nanofluids in a porous medium. Blood viscosity, which changes with temperature, is taken into account using the Reynolds viscosity model. The finite difference approach is used to quantitatively solve the governing equations. For use in medical applications, the effects of the physical parameters on velocity, temperature and concentration along the radial axis have been investigated and physically interpreted. The results are graphically displayed and physically defined in order to facilitate comprehension of the various phenomena that occur in the artery when nanofluid is present. It is observed that the Soret effect increases the rate of heat transfer but decreases the rate of mass transfer. The new study enhances knowledge of non-surgical treatment options for stenosis and other abnormalities, hence reducing post-operative complications. Additionally, current research may have biomedical applications such as magnetic resonance angiography (MRA), which provide a picture of an artery and enable identification of any anomalies, and thus may be useful

Published: April 2023

The major part of the radiation dose that humans receive from natural radioactive sources is due to inhalation of radon and its decay products. The study focuses on radon concentration (CRn) investigation in kindergartens and nurseries in the district of Montana. The influence of building characteristics on CRn was evaluated. The measurement of the CRn was performed using passive detectors. The survey was carried out between December 2019 and May 2020 with a total number of 602 detectors. The average value of CRn in the premises of the studied kindergartens and nurseries in this district is 125 Bq·m−3, and the geometric mean (GM) value is 88 Bq·m−3. The buildings that have built ventilation and sewerage systems have lower CRn. The effective doses of the children and workers were evaluated in order to assess the radon exposure.

Published: April 2023

OBJECTIVES. We investigated peripheral smell regions in patients with central vertigo by cranial magnetic resonance imaging (MRI).

MATERIAL AND METHODS. In this study, 137 adult patients were included by selecting cranial MRI images from the hospital’s PACS system, covering both recent and past records. The first group included 68 adult patients suffering from central vertigo, and the control group (Group 2) 69 healthy individuals, who had no central vertigo. Measurements of olfactory bulb (OB) volume and olfactory sulcus (OS) depth were taken from all groups.

RESULTS. The study found that the OB volume of the group with central vertigo was significantly lower compared to the control group (p<0.05). However, there were no significant differences in the OS depth between the two groups (p>0.05). In both groups, there were no significant variations in OB volume between the right and left sides (p>0.05). Additionally, both the central vertigo group and the control group showed that the left OS depth was lower than the right side (p<0.05). Positive correlation was seen between OB volume and OS depth on both left and right sides as well as bilateral OB volume and OS depth in the central vertigo group. However, there were no significant correlations between OB volume, OS depth and age and gender in the central vertigo group.

CONCLUSION. We concluded that OB volume got lower in patients with central vertigo. However, there were no side differences between OB volumes. As central vertigo secondary to cerebral ishchemia causes olfactory disorders, measures should be taken to prevent central vascular problems. From another perspective, olfactory problems may be one of the initial signs of central vascular problems and central vertigo.

BACKGORUND. Sleep is a complex biological process and represents a reversible state of unconsciousness in which metabolism and motor activity are reduced. Sleep disorders are a group of conditions that disrupt a person’s normal sleep patterns. Sleep disorders are one of the most common clinical problems encountered. Inadequate or non-restorative sleep can interfere with normal physical, mental, social and emotional functioning. Sleep pathology is a frequent condition, but often underdiagnosed.

MATERIAL AND METHODS. In this retrospective study, we aimed to investigate patients with suspected obstructive sleep apnea syndrome based on the response to the Berlin Questionnaire, which suggests the presence of an increased or decreased risk of sleep disorders. We conducted a study in patients with cardiovascular, metabolic, pulmonary antecedents, which were associated with risk factors, such as: age, body mass index, neck circumference, abdominal circumference, history of snoring.

RESULTS AND CONCLUSIONS. The Berlin Questionnaire is a useful tool for detecting mild, moderate and severe apnea syndrome, being used for its early diagnosis, especially in cases where polysomnography is more difficult to perform, in order to select patients for the continuation of the examination protocols. This questionnaire is a reliable tool for the exclusion of obstructive sleep apnea and can be a particularly important tool in the allocation of diagnostic resources in patients suspected of having a breathing disorder during sleep.

BACKGROUND. The registration of the nasal cycle by separate measurement of breathing through the left and the right nostril appears a non-invasive method, in which the passability of the nostrils is assessed by the respiratory amplitudes of the air.

OBJECTIVE. To present the dynamics and periods of the nasal cycle during night sleep using the Interface 2-Channel System Method.

MATERIAL AND METHODS. The recordings demonstrate the dynamics and periods of the nasal cycle during the night sleep of a healthy volunteer.

RESULTS. The patient respiratory and nasal cycle through the left and right nostril was measured separately for 10 hours. The entire record consisted of 3 large nasal cycles lasting 4.0h, 3.5h and 2.5h, separated by short awakenings, getting out of bed lasting no longer than 10 minutes. Each part was composed of smaller cycles that structure separate stages of the nasal and sleep cycles. The smallest period recorded in the nasal cycle was about 4 minutes long. Records show that the duration of the REM stage must be longer than 20 minutes to perform the nasal cycle reversal. In the presented records, the nasal cycle reversals were performed after a 30-minute duration of the REM stages. It has been found that nasal cycles can change fast (impulse change) and gradually (gradual change). The impulse change implies that the passability of only one nostril lasts for about 12 seconds, while the other nostril retains its passability. The slow gradual changes of the nasal cycle involve both nostrils and continue for about 4 minutes. Waking up and getting up of persons for about 10 minutes restarts the nasal cycle with potential for a new nasal cycle reversal.

CONCLUSION. The method provides an objective assessment of nasal resistance, which can be used in the diagnosis of patients with breathing disorders during sleep.

Published: April 2023

Introduction: Appetite traits (RA) are part of the eating behavior of the person, with a series of continuous responses that are related to the choice and consumption of food, but also to aspects at the moment in which the feeding is carried out, the frequency of meals, the place where they take place, the company with which they are shared, among others. These factors can have a significant impact on the way a person eats and on their long-term health. Objective: To analyze the possible connection between maternal eating behavior, with the body composition of the adolescent, from a high school in the city of Allende, Nuevo León, Mexico. Material and methods. A quantitative, cross-sectional and correlational study was carried out. The period of the present study was February-August 2022, the population was 41 couples (mother and adolescent son between 12 and 17 years old), from a high school in the municipality of Allende, Nuevo León, Mexico. To test the hypothesis, Spearman's correlation coefficient was obtained. Results. When running the statistical test, it was found that there is no significant correlation between the level of eating behavior of the mother and the body composition of the adolescent (r = -0.174, p = 0.277), therefore, the hypothesis of investigation. Conclusions. It was found that the eating behavior of the mother is not significantly related to the body composition of the adolescents with the sample considered in the present study.
Is reconstructing anterior sternoclavicular joint dislocation by a high-strength tape suture a good choice?

Published: April 2023

Objectives:

Sternoclavicular joint (SCJ) dislocation is uncommon but dangerous. Redislocation frequently occurs after manual reduction due to the torn ligaments of the joint with a high-energy injury, which is often the case. Reconstruction of the SCJ is recommended to avoid poor efficacy of conservative treatment and decreasing quality of life in the patient due to progressive pain limiting the movement of the shoulder girdle. Our study aimed to evaluate the efficacy, safety, and patient satisfaction using a high-strength non-absorbable tape suture to reconstruct the anterior SCJ dislocation.

Methods:

This study included ten patients (Nine males and one female) who presented with acute anterior dislocation of the SCJ (six on the right and four on the left side). Our patients’ average age was 40.1 years (18–52 years), with 12 months on average follow-up (9–18 months). Four patients had isolated anterior SCJ dislocation, while the others had associated injuries.

Results:

All patients had excellent functional and satisfactory outcomes and returned to the pre-injury activity level. No intraoperative or major post-operative complications were recorded, and no injuries to near structures or wound problems were noted. The mean improvement of physical function measured by the American shoulder and elbow score was 24.59, which increased from 68.11 ± 3.72 preoperatively to 92.70 ± 3.54 postoperatively.

Conclusion:

The technique of open reconstruction of anterior SCJ dislocation using high-strength nonabsorbable tape sutures is recommended because it gave us excellent results regarding the safety, functional outcome, patient satisfaction, and avoidance of other surgical site morbidities.

THE NEW RANK ONE CLASS FOR UNCONSTRAINED PROBLEMS SOLVING
Authors: Mustafa Ahmed
Published: April 2023

One of the most well-known methods for unconstrained problems is the quasi-Newton approach, iterative solutions. The great precision and quick convergence of the quasi-Newton methods are well recognized. In this work, the new algorithm for the symmetric rank one SR1 method is driven.
The strong Wolfe line search criteria deﬁne the step length selection. We also proved the new quasi-Newton equation and positive definite matrix theorem. Preliminary computer testing on the set of fourteen unrestricted optimization test functions leads to the conclusion that this new method is more effective and durable than the implementation of classical SR1 method in terms of iterations count and functions.
Nanodroplet-based reagent delivery into water-in-fluorinated-oil droplets

In vitro compartmentalization is a technique for generating water-in-oil microdroplets to establish the genotype (DNA information)-phenotype (biomolecule function) linkage required by many biological applications. Recently, fluorinated oils have become more widely used for making microdroplets due to their better biocompatibility. However, it is difficult to perform multi-step reactions requiring the addition of reagents in water-in-fluorinated-oil microdroplets. On-chip droplet manipulation is usually used for such purposes, but it may encounter some technical issues of low throughput or time delay of reagent delivery into different microdroplets. Hence, we evaluated the feasibility of employing a nanodroplet-based approach to address these issues using copper ions and a middle-size peptide (2 kDa) molecule.
