Using the Possible Me Tree Model to Identify Resilience Enabling Relationships for Young People Exiting Residential Care
Authors: Bond Sue
Published: September 2023

The importance of relationships for young people exiting residential care is noted extensively in the care-leaving literature. Helpful and supportive relationships cushion care leavers as they exit the statutory system and provide a network of supports that may develop resilience, facilitate their journeys into independence, and contribute towards better outcomes for young people who have experienced care. However, the available literature suggests that social workers are not skilled at identifying relationships that young people in care consider to be important. This article draws on a qualitative study conducted in four Child and Youth Care Centres in Eastern Cape, South Africa. This was a qualitative study using a phenomenological design. Twelve participants were interviewed using the possible me tree model, which requires participants to draw a tree with three aspects of their future selves. The participants were interviewed using a semi-structured interview schedule which included relationship specific questions. The young people identified relationships with their care workers, relatives, sports coach/es, and partner and partner’s family as significant. From this it may be suggested that the possible me tree may be used to identify relationships that young people regard as important, and which may serve as resilience enablers. It is recommended that more studies using this approach, which include a longitudinal component, would add to this initial study.
Viscoelastic Testing on Venoarterial Extracorporeal Membrane Oxygenation: Need or Greed?
Authors: Kapoor Poonam Malhotra , Prakash Mohit , Mujahid Omer Mohammed , Badge Mohanish , Thiruselvan T. , Garg Sanchita
Published: September 2023

Extracorporeal life support (ECLS) is a life support modality that is being used in life-threatening cardiac and/or respiratory failure; in neonates, children, and adults. The risk of bleeding and other coagulation-related issues is unavoidable. Hence, while conducting ECLS, a patient-tailored approach is better than the generalized approach for bleeding management. There are no established guidelines for heparin use and its monitoring during ECLS in a bleeding patient on VA ECMO. Likewise, heparin and its adjuncts, though mentioned in the literature, have no consensus on what exact steps to follow in an adverse condition. Having a protocol for anticoagulation and its monitoring is of paramount importance in any center practicing ECLS. This review aims to seek the incidence of bleeding and thrombosis while on ECMO with the use of routine anticoagulant heparin and justify the need for the use of viscoelastic tests on VA ECMO.
Specifics of the Vocal Style of Gioachino Rossini’s Operas: Tradition and Innovation
Authors: Лю С.
Published: September 2023

Статья посвящена выявлению в оперных партиях Россини характерных черт староитальянских вокальных традиций и новых способов работы композитора с  вокально-мелодическим материалом. Будучи адептом итальянского bel canto XVIII в., Россини сохранил в своих операх его основополагающие черты. Среди них выделяются: непродолжительность вокальных фраз, сосредоточенность мелодики в удобной тесситуре, насыщение колоратурой всех вокальных партий (включая басовые), избегание потенциально опасного переходного регистра в быстрых и сложных пассажах. Так же, как другие композиторы bel canto, Россини ориентировался на хорошо подготовленных певцов, в совершенстве владеющих выровненным тембром, головным голосом, навыками точного интонирования, пения legato, portamento и messa di voce. В то же время итальянский мастер насытил вокальный стиль новыми чертами, главная из которых заключалась в том, что колоратура стала сущностной основой вокальной мелодии и важнейшим выразительным средством.

The paper identifies distinctive features of the Old Italian vocal tradition and the new ways that Rossini used to work with vocal and melodic material in his opera parts. Being a follower of the Italian bel canto of the XVIII century, Rossini preserved its fundamental characteristics in the operas, namely: shorter vocal phrases, concentration of the melodics in a convenient tessitura, saturation with coloratura of all the vocal parts, including the bass ones, avoiding a potentially dangerous transitional register in fast and complex passages. Like other bel canto composers, Rossini focused on well-trained singers who perfectly mastered the smooth timbre, voce di testa, skills of precise intoning, legato, portamento and messa di voce singing. At the same time, the Italian master saturated the vocal style with new features, the main one being that coloratura became the essential basis of vocal melody and the most important expressive means.

Published: September 2023

We present structural models for three different amyloid fibril polymorphs prepared from amylin20−29 (sequence SNNFGAILSS) and amyloid-β25−35 (Aβ25−35) (sequence GSNKGAIIGLM) peptides. These models are based on amide C=O bond and Ramachandran ψ-dihedral angle data from Raman spectroscopy, which were used structural constraintsto guide molecular dynamics (MD) simulations. The resulting structural models indicate that the basic structural motif of amylin20−29 and Aβ25−35 fibrils are extended β-strands. Our data indicates that amylin20−29 forms both antiparallel and parallel β-sheet fibril polymorphs, while Aβ25−35 forms a parallel β-sheet fibril structure. Overall, our work lays the foundation for using Raman spectroscopy in conjunction with MD simulations to determine detailed molecular-level structural models of amyloid fibrils in a manner that complements gold-standard techniques such as solid-state NMR and cryogenic electron microscopy.
Identifying the active species in a cobalt-based covalent organic framework for the electrochemical oxygen evolution reaction

Published: September 2023

While considerable efforts have been devoted to developing functionalized covalent organic frameworks (COFs) as oxygen evolution electrocatalysts in recent years, studies related to the identification of the true catalytically active species for the oxygen evolution reaction (OER) remain lacking in the field. In this work, we investigated the active species of a cobalt-functionalized COF (TpBpy-Co) as electrochemical OER catalyst through a series of electrochemical measurements and post-electrolysis characterizations. Our results demonstrate that Co(II) ions, coordinated to the COF backbone, are transformed to cobalt-based nanoparticles when exposing TpBpy-Co to alkaline media. These nanoparticles act as the true active species for oxygen evolution. It remains unclear whether intact TpBpy-Co acts as a secondary catalytic species, due to its structural instability in alkaline electrolyte and its inferred lower catalytic activity compared to cobalt-based nanoparticles. Our results highlight that caution is warranted when identifying the active species for COF electrocatalysts formed under catalyst working conditions. Specifically, strong coordination between COFs and metal centers under electrochemical operation conditions is crucial to avoid unintended transformation of COF electrocatalysts. Our study thus contributes to the rational development of earth-abundant COF OER catalysts for the production of green hydrogen from renewable resources.

Published: September 2023

Herein we report the preparation and characterization of the Group 13 metal complexes of a tripodal tris(nitroxide) based ligand, designated (TriNOx3−)M (M = Al (1), Ga (2), In (3)). Complexes 1 and 2 both activate the O–H bond of a range of alcohols spanning a ~13 pKa unit range via an element-ligand cooperative pathway to afford the zwitterionic complexes (HTriNOx2–)M–OR. Structures of these alcohol adduct products are discussed. We demonstrate that the thermodynamic and kinetic aspects of the reactions are both influenced by the identity of the metal, with 1 having higher reaction equilibrium constants and proceeding at a faster rate relative to 2 for any given alcohol. These parameters are also influenced by the pKa of the alcohol, with more acidic alcohols reacting both to more completion and faster than their less acidic counterparts. Possible mechanistic pathways are discussed.
Contrast variation method applied to structural evaluation of catalysts by X-ray small-angle scattering

Published: September 2023

In the process of developing carbon-supported metal catalysts, determining the catalyst particle-size distribution is an essential step, because this parameter is directly related to the catalytic activities. The particle-size distribution is most effectively determined by small-angle X-ray scattering (SAXS). When metal catalysts are supported by high-performance mesoporous carbon materials, however, their mesopores may lead to erroneous particle-size estimation if the sizes of the catalysts and mesopores are comparable. Here we propose a novel approach to particle-size determination by introducing contrast variation-SAXS (CV-SAXS). In CV-SAXS, a multi-component sample is immersed in an inert solvent with a density equal to that of one of the components, thereby rendering that particular component invisible to X-rays. We used a mixture of tetrabromoethane and dimethyl sulfoxide as a contrast-matching solvent for carbon. As a test sample, we prepared a mixture of a small amount of platinum (Pt) catalyst and a bulk of mesoporous carbon, and subjected it to SAXS measurement in the absence and presence of the solvent. In the absence of the solvent, the estimated Pt particle size was affected by the mesopores, but in the presence of the solvent, the Pt particle size was correctly estimated in spite of the low Pt content. The results demonstrate that the CV-SAXS technique is useful for correctly determining the particle-size distribution for low-Pt-content catalysts, for which demands are increasing to reduce the use of expensive Pt.

Cholesterol plays a crucial role in biomembranes by regulating various properties such as fluidity, rigidity, permeability, and organization of lipid bilayers. The latest version of the Martini model, Martini 3, offers significant improvements in interaction balance, molecular packing, and the inclusion of new bead types and sizes. However, the release of the new model resulted in the need to re-parameterize many core molecules, including cholesterol. Here, we describe the development and validation of a Martini 3 cholesterol model, addressing issues related to its bonded setup, shape, volume and hydrophobicity. The proposed model mitigates some limitations of its Martini 2 predecessor while maintaining or improving overall behavior.
δ-bonding and spin-orbit coupling make SrAg4Sb2 a topological insulator
Authors: Morgan Harry , Laderer William , Alexandrova Anastassia
Published: September 2023

Bonding interactions and spin-orbit coupling in the topological insulator SrAg4Sb2 are investigated using DFT with orbital projection analysis. Ag-Ag delta bonding is a key ingredient in the topological insulating state because the 4dxy + 4dx2−y2 delta antibonding band forms a band inversion with the 5s sigma bonding band. Spin-orbit coupling is required to lift d orbital degeneracies and lower the antibonding band enough to create the band inversion. These bonding effects are enabled by a longer-than-covalent Ag-Ag distance in the crystal lattice, which might be a structural characteristic of other transition metal based topological insulators. A simplified model of the topological bands is constructed to capture the essence of the topological insulating state in a way that may be engineered in other materials.
Mixed-Cation Vacancy-Ordered Perovskites (Cs₂Ti₁₋ₓSnₓX₆; X = I, Br): High Miscibility, Additivity and Tunable Stability

Published: September 2023

Lead toxicity and poor stability under operating conditions are major drawbacks impeding the widespread commercialization of metal halide perovskite solar cells. Ti(IV) has been considered as an alternative species to replace Pb(II) because it is relatively non-toxic, abundant and its perovskite-like compounds have demonstrated promising performance when applied in solar cells (η > 3%), photocatalysts and non-linear optical applications. Yet, Ti(IV) perovskites show instability in air, hindering their use. On the other hand, Sn(IV) has a similar cationic radius to Ti(IV), adopting the same vacancy-ordered double perovskite (VODP) structure and showing good stability in ambient conditions. We report here a combined experimental and computational study on mixed titanium-tin bromide and iodide VODPs, motivated by the hypothesis that these mixtures may show a higher stability than the pure titanium compositions. Thermodynamic analysis shows that B-site cations are highly-miscible in these vacancy-ordered structures. Experimentally, we synthesized mixed titanium-tin VODPs as nanocrystals across the entire mixing range x (Cs₂Ti₁₋ₓSnₓX₆; X = I, Br), using a colloidal synthetic approach. Analysis of the experimental and computed absorption spectra reveals weak hybridization and interactions between Sn and Ti octahedra, with the alloy absorption being essentially a linear combination of the pure Sn and Ti compositions. These compounds are stabilized at high percentages of Sn (x ~ 60%), as expected, with bromide compositions demonstrating greater stability compared to the iodides. Overall, we find that these materials behave akin to molecular aggregates, with the thermodynamic and optoelectronic properties governed by the intra-octahedral interactions.
The idea of a nation for the masses and the idea of a nation for the people
Authors: Ageev A. V.
Published: September 2023

Today, nationalism is being rethought in the context of the difference between constructivist nationalism and ontological nationalism. If in the first the idea of the nation strives to ensure that the masses grow by leaving the people as the subject of history, then in the second the national idea, on the contrary, means the departure of the masses from the historical stage. The social reality constructed for the masses is distinguished by the loss of interest in consolidating thinking as an immanent state of culture. It is in this context that the idea of the nation appears for the masses, as a loss of connection with the national idea. For the people, such an idea of the nation is detrimental, because what matters to them is not the constructed, but the successive idea of the nation, as a situational self-actualization of the national idea. Therefore, in the context of social consolidation, methodologically important is the difference between the idea of a nation for the masses and the idea of a nation for the people.
Ethnopsychological and cross-cultural trends in the development and assessment of resources of the multipolar world (Western and Eastern approaches)
Authors: Karnyshev A. D.
Published: September 2023

The multipolar world (MPM) is a more complex formation of planetary official and unofficial communities than a modern planetary organization, since it presupposes the emergence of new centers of international influence and consolidation of ethno-cultural "subjects" – countries, peoples, ethno-cultural associations – around them. In expanding Russia's cooperation with Eastern countries, primarily with China, it is impossible not to take into account the changes in the mass consciousness of the Eastern peoples that are manifested today. Russia's turn to the East requires taking into account not only the established traditions of interaction and emerging innovations, but also the opinions of the indigenous peoples of Siberia about the MPM and the prospects for their development, especially since Western politicians talk about the need for these peoples to go out of touch with Russia.
Thermodynamic approaches in the study of environmental problems
Authors: Bezsonnyi V. L.
Published: September 2023

Purpose. Analysis from the thermodynamic point of view of the causes of global environmental problems and the possibilities of overcoming them.

Results. The application of the laws of thermodynamics to attempts to solve environmental problems is analyzed. The existence of life and the biosphere as a whole is determined by the flow of energy, the intensity of which per unit weight of living beings significantly exceeds the specific intensity of energy transformation in the Sun. From the second law of thermodynamics, a conclusion is made about the objectivity of environmental pollution, since the efficiency of energy transformation is always less than 100%, and is 1-50%. The remaining part of the degraded energy is the main cause of environmental pollution. The emergence of many global environmental problems is directly related to this part of energy. There is continuous exponential growth in both population and energy consumption. A critical overview of the existence and development of global environmental problems is given. The development of population growth is predicted for the current century.

Conclusions. Possible ways to overcome global environmental problems are discussed. The need to develop a new paradigm of human interaction with the environment is confirmed.
The Role of Servant Leadership Style in Improving Innovation in Higher Education Institutions
Authors: Maalouf Georges Y.
Published: September 2023

Purpose: The research aims to empirically study the role of adopting a servant leadership style in improving innovation in higher education institutions.
 
Theoretical framework: (Piorun et al., 2021) cited that servant leadership will make people emerge as the power will flow down to the subordinates. (Geuther, C. 2014) mentioned that servant leaders can establish a supportive workplace and promote the employees’ self-esteem. In addition, Chinese philosophers in the 5th century BC such as Laozi agreed that servant leaders are those who are characterized by people who say, "we did it ourselves” when things are done (Tarallo, 2021).  In the current study, the researcher will explore the adoption of Servant Leadership in Higher Education Institutions, and its influence on the innovation of these institutions.
 
Design/methodology/approach: The researcher adopted a quantitative research methodology. The research design is as follows: objectivism research ontology, positivism research philosophy, the research approach is deductive, and the research choice is mono-method quantitative. The research strategy is a survey, and the time horizon is cross-sectional. Items of the questionnaire were adopted and adapted from the Servant Leadership Questionnaires published by (Liden et al., 2008), (Northouse, n.d.), and (Hess & Dumas, 2015). Primary data was collected from higher education institutions and the secondary data was from trusted previous studies found on Google Scholars. The sample size is 208 respondents, and data was collected using Survey Monkey, the online survey development tool to gather data and feedback. Collected Data were statistically analyzed utilizing SPSS, starting with descriptive analysis, followed by Reliability Analysis, Factor Analysis, Chi-Square Test, and Regression Analysis using ANOVA and T-Test.
 
Findings:  The researcher found that the behavior of servant leaders will play a key role in promoting innovation, and as she/he is a role model, the possession of highly ethical practices has a positive relationship with learners’ satisfaction. In addition, asking for career goals will help strengthen employees' experience in this institution.
The campus environment, its maintenance, and attractiveness play a role in increasing the university’s fees.
 
Research, Practical & Social implications:  The results will set the path in which innovation will be cultivated at the level of the whole higher education institutions by focusing on the set of patterns of behaviors adopted by the leaders.
 
Originality/value: This study is among the first to tackle servant leadership and innovation in higher education institutions. In addition, this will add to the knowledge in Academia about servant higher education institutions.

Purpose: Financial performance is the main standard in a company. This study aims to analyze the influence of Characteristics of Female Directors which investigates the relationship between the presence of female directors on corporate boards and management earnings, with a special focus on the specific attributes of female directors on financial performance and analyzing earnings management on financial performance.
 
Theoretical framework:  Gender Diversity, Director Affiliation, Director Characteristics, female directors and earnings management as independent variables, while financial performance with ROA as the dependent variable.
 
Design/methodology/approach:   The control variable are ROE, leverage, directors, block owners, family dummy, and size board. Earnings management is measured by Discretionary Accruals Net Profit - Cash and Cash Equivalents/Total Assets t-1) and financial performance using ROA (Return On Assets). The data used in this research is secondary data. The total population used in this study were 17 building construction sub-sector companies listed on the Indonesia Stock Exchange. The data collection technique in this study was purposive sampling and data were obtained from 8 companies. The analytical method uses the classical assumption test, multiple linear regression test, test the coefficient of determination, and test the hypothesis.
 
Findings: Based on the results of the study it can be concluded that the presence of female directors on company boards is not related to profit management. Similar results were obtained for the percentage of female directors with certain attributes such as busyness, expertise professionals, and audit committee membership. Surprisingly, the results show that there is a negative (positive) relationship between the percentage of affiliated (unaffiliated) female directors with controlling business groups and management profit. Simultaneously significant effect on ROA. Partially, Gender Diversity, Director Affiliation, Director Characteristics, female directors and earnings management each have an effect on ROA.
 
Research, Practical & Social implications:   In further research, in order to conduct a broader research with other objects. The research is expected to be used for all companies.

The Role of Social Support and Patient Empowerment Through Online Health Communities in Enhancing Patient–Physician Relationship
Authors: Okour Mohammad-Noor Said Deeb
Published: September 2023

Purpose: The goal of this project is to investigate how online health communities can improve patient-physician relationships by providing social support and patient empowerment.

 

Theoretical framework: Nowadays, on online health forums, patients can connect with other patients and healthcare professionals and share knowledge and experiences. However, there is a dearth of research on how patient-physician relationships might be improved via online health communities. 

 

Design/Methodology/Approach: In this analytical study, a sample of 61 individuals receiving treatment in Jordan's private hospitals were given a questionnaire via two of the most popular health communities' Facebook pages.

 

Findings: The findings showed that while patient empowerment had no impact on the patient-physician connection, computer-mediated social support had an impact on that relationship. These findings support the need to suggest Jordanian online health community models that might strengthen this kind of engagement.  

 

Research, Practical and Social Implications: Online health community providers need to be aware of the tactics they should use in these communities to strengthen the patient-physician relationship and integrate these efforts into patient treatment. Additionally, these communities can help medical practitioners ensure that patients receive the appropriate information and type of support.

 

Originality/Value: As online health groups grew, so did the number of patients who relied on them for information and emotional support. Although the majority of studies focused on this type of support, little is known about how it affects the patient-physician interaction.
Osobliwości w dochodzeniu roszczeń z tytułu naruszenia obowiązku informacyjnego przez ubezpieczyciela w prawie niemieckim – rozważania o efektywności modelu
Authors: Zgonina Oskar
Published: September 2023

Przedkontraktowe obowiązki informacyjne ubezpieczycieli stały się głównym narzędziem ochrony klientów rynku usług ubezpieczeniowych w prawie unijnym. Wyrazem przyjęcia tzw. modelu informacyjnego w Niemczech jest nałożenie na ubezpieczycieli obowiązku informacyjnego (Informationspflicht) oraz obowiązku doradczego (Beratungspflicht). Nieprawidłowości w zakresie wykonywania wskazanych obowiązków prowadzą do powstania problemów na polu odpowiedzialności cywilnoprawnej. Naruszenie obowiązku informacyjnego oraz obowiązku doradczego w Niemczech może skutkować powstaniem odpowiedzialności cywilnej w reżimie culpa in contrahendo. Celem artykułu jest ocena efektywności modelu dochodzenia roszczeń z tytułu naruszenia obowiązków informacyjnych ubezpieczycieli w prawie niemieckim. Rozważania we wskazanym temacie zostały przeprowadzone na podstawie aktualnych poglądów niemieckiej doktryny i judykatury.
Pozasądowe modele kompensacji szkody medycznej w wybranych krajach Unii Europejskiej – poszukiwanie optymalnego rozwiązania
Authors: Serwach Małgorzata
Published: September 2023

Przedmiotem artykułu są przyjęte w poszczególnych systemach europejskich pozasądowe modele kompensacji szkody medycznej. Autorka rozpoczyna swoje rozważania od wskazania przyczyn wprowadzenia uproszczonych modeli w zakresie odpowiedzialności za szkodę wyrządzoną pacjentowi w związku z leczeniem. Wskazuje na ich cechy wspólne oraz podstawowe różnice. Następnie przedstawia, według przyjętego przez siebie podziału: skandynawski model ochrony ubezpieczeniowej pacjentów oparty na first-party insurance, francuski model ubezpieczeniowy wsparty subsydiarną odpowiedzialnością państwa na zasadzie solidarności narodowej oraz quasi-ubezpieczeniowe modele zakładające możliwość zaspokojenia roszczeń pacjentów z odrębnych funduszy. W tym ostatnim przypadku zostały omówione rozwiązania austriackie i angielskie. W ostatniej części opracowania autorka prezentuje polskie regulacje oraz podstawowe zasady prowadzenia postępowania przez Wojewódzkie Komisje ds. Orzekania o Zdarzeniach Medycznych, wskazując na ich zasadnicze wady. Dowodzi, że sugerowana propozycja likwidacji obowiązującego modelu i wprowadzenie w to miejsce nowego, stanowiącego kompilację różnych rozwiązań stosowanych w Europie może nie doprowadzić do oczekiwanego efektu, czyli skutecznej indemnizacji szkody medycznej. Przeciwnie, może oznaczać zastąpienie wadliwego rozwiązania – nowym, równie wadliwym. W końcowych rozważaniach wskazano, jakie należałoby podjąć działania, aby uzyskać optymalny, a przede wszystkim skuteczny system kompensacji szkody medycznej.
Sądowe postępowanie egzekucyjne z nieruchomości stanowiącej przedmiot umowy ubezpieczenia
Authors: Maśniak Dorota , Kamiński Łukasz
Published: September 2023

Jednym z rodzajów postępowania egzekucyjnego jest egzekucja z nieruchomości. Może się zdarzyć, że nieruchomość jest objęta ochroną ubezpieczeniową. W związku z tym pojawia się pytanie, komu należy się odszkodowanie, gdy następuje zdarzenie ubezpieczeniowe. Kwota odszkodowania może być przeznaczona do podziału pomiędzy wierzycieli albo na pokrycie szkody. Wydaje się, że odpowiedź na powyższe pytanie zależy od chwili, kiedy nastąpi zdarzenie ubezpieczeniowe. Jeżeli zdarzenie ubezpieczeniowe następuje w toku sądowego postępowania egzekucyjnego, kwoty odszkodowania nie może otrzymać dłużnik. Kwota ta, podobnie jak inne roszczenia wynikające z umowy ubezpieczenia, musi zostać przeznaczona na naprawę szkody. W niniejszym artykule autorzy starają się również odpowiedzieć na pytanie, czy kwota ta, stanowiąca de facto o wzroście wartości nieruchomości, powinna być uiszczona przez nabywcę.

Published: September 2023

La biorremediación utilizando sustancias húmicas es una de las técnicas recientes y prometedoras para la restauración de suelos contaminados por hidrocarburos, pero existe poca información sobre su comportamiento en los diversos tipos de suelo. Por estas razones, esta investigación tuvo como objetivo evaluar la remoción de hidrocarburos totales del petróleo o HTP en tres suelos con diferentes texturas (S1, S2 y S3) y tratados con enmiendas orgánicas de vermicomposta (cascarillas de cacao, Theobroma cacao; arroz, Oriza sativa; bagazo de caña, Saccharum of ficinarum; estiércol de vaca) y sustancias húmicas comerciales (humato de potasio). Se planteó un diseño experimental multifactorial aleatorio (3 × 3 × 2), constituido por tipo de suelo, enmienda orgánica (sin vermicomposta, con vermicomposta orgánica, con sustancias húmicas comerciales), y carga microbiana (con microorganismos, sin microorganismos). Los resultados fueron analizados mediante las pruebas ANOVA-Tukey en el programa Statgraphics Centurion TM V.18 (α = 0.05) con el fin de evaluar diferencias significativas entre los tratamientos. Los resultados muestran que S2 con vermicomposta orgánica tuvo la mayor remoción (86% de HTP) luego de 60 días de incubación, en comparación con el tratamiento con sustancias húmicas comerciales, relacionándose con la baja biodisponibilidad de microorganismos. Este comportamiento también se observó en S3, el cual tuvo un porcentaje de remoción de HTP de 77.52 y 63.4%. Finalmente, la tasa de crecimiento celular fue mejor en S2 con sustancias húmicas comerciales. Se obtuvo un crecimiento promedio de 94×104 UFC g-1 de suelo durante los 60 días de evaluación del experimento, y un máximo de 98×105 UFC g-1 de suelo a los 45 días de tratamiento. Se concluye que el uso de vermicomposta es adecuada para suelos arcillosos, ya que las tasas de degradación son mayores en ellos. Además, representan una alternativa de menor costo que los tratamientos sintéticos y de revalorización de residuos orgánicos.
Producción de acelga (Beta vulgaris var. cicla L.) con efluente del cultivo de robalo (Centropomus viridis) en un sistema acuapónico

Published: September 2023

En los ecosistemas de zonas áridas y semiáridas la producción de alimentos es cada vez más compleja. Uno de los efectos más importantes es la desertificación donde el agua tiene un papel primordial. Por lo que, buscar estrategias de producción de alimento inocuo y de forma sustentable, es el reto actual. La producción de alimento mediante acuaponía es una alternativa para dar respuesta a esta problemática. En la Península de Baja California, las bajas precipitaciones anuales y las características geográficas hacen de forma natural que el agua sea escasa; pero si a esto se le suma el factor antropogénico, tenemos como resultado, acuíferos en su mayoría salobres. Bajo este contexto se analizó la eficiencia en el uso del efluente del cultivo de robalo, en el crecimiento de la acelga, en un sistema acuapónico. Se midieron los parámetros fisicoquímicos del efluente del robalo y cómo influyen en la respuesta morfométrica en la acelga bajo sistema hidropónico. La respuesta se comparó con un sistema tradicional con efluente de agua de pozo y con fertilización convencional. Se obtuvo mayor crecimiento en las plantas en sistema hidropónico, pero con efluente de agua de cultivo de robalo (con diferencia significativa en longitud, biomasa, área foliar y número de hojas). Este estudio demostró la eficiencia del uso del efluente del cultivo de robalo en el crecimiento y desarrollo de la acelga. Este conocimiento generará futuras investigaciones con aplicación en innovación biotecnológica que podrán ser empleadas por la sociedad, con beneficios por la capacidad de cultivar especies de calidad en densidad, aprovechar los nutrientes, controlar la disponibilidad de agua, aprovechar y mejorar las condiciones climáticas.

Las nanopartículas de quitosán (NPsCS) son utilizadas como bioestimulantes naturales en la agricultura sustentable, ya que incrementan la productividad de los cultivos e inducen la síntesis de antioxidantes enzimáticos y no enzimáticos, protegiendo a la planta del estrés. El presente estudio se desarrolló con el objetivo de determinar el efecto de la aplicación foliar de las NPsCS sobre el rendimiento, actividad enzimática y contenido de compuestos bioactivos en frutos de tomate. El ensayo se estableció en un diseño completamente al azar con seis dosis crecientes de NPsCS: 0, 0.05, 0.1, 0.2, 0.4 y 0.8 mg mL-1. La aspersión foliar de 0.2 mg mL-1 aumentó el rendimiento, tamaño y firmeza de los frutos; en cambio dosis alta incrementan los compuestos bioactivos y la actividad enzimática. El uso de NPsCS aplicadas de forma foliar presentan un gran potencial para utilizarse como bioestimulantes para mejorar el rendimiento y obtener alimentos funcionales.

Üniversite çalışanları ve öğrenciler yaşamlarının büyük bir bölümünü kapalı ortamlarda geçirmekte ve bu ortamlarda bulunan hava kirleticilere maruz kalmaktadırlar. Bu insanlar farkında bile olmadan hasta bina sendromu belirtilerine maruz kalmakta, kişisel önlem görüşüyle çözüm aramaktadırlar. Bir devlet üniversitesinde yapılan bu çalışmada, ders çalışma, yemek yeme ve sosyal aktivitede bulunma gibi farklı aktivitelerin yapıldığı alanlarda, iç ortam hava kalitesi (İOHK) parametrelerinden sıcaklık, nem ve CO2 konsantrasyonu ölçümleri yapılmış ve sonuçları analiz edilmiştir. Farklı havalandırma tesisatlarına sahip bu alanlardan alınan veriler sonucunda, İOHK parametrelerinden CO2 konsantrasyonunu ile sıcaklığın kişi sayısı ve yapılan aktiviteye göre doğrusal değiştiği, nemin ise ortamda havalandırma tesisatı bulunmasıyla olumlu yönde iyileştiği görülmüştür. Çalışma sonuçları, benzer çalışma alanlarındaki İOHK parametrelerine ve alınması gereken önlemlere yönelik bilimsel veriler sunmaktadır. Ayrıca sonuçlar, sürdürülebilir iş sağlığı ve güvenliği bakış açısıyla irdelenmiş, kişisel önlemlerden ziyade mühendislik tedbirleri yönünden değerlendirme yapılarak çözüm önerileri sunulmuştur.
Umutsuzluk, Ölüm ve Tatminsizliğe Edebi Bakış: Tatar Çölü
Authors: YILDIRIM Tamer
Published: September 2023

Yazar Dino Buzzati (1906-1972), tarihsel ortamı, kişisel felsefesi, hem gazeteci hem de sanatçı olarak deneyimlerinin farklı yönlerini algısal bir şekilde birleştirmiştir. Yazdığı Tatar Çölü adlı romanında kendini çöllere hapsetmiş ve hapsedecek olan insanları anlatmıştır. Romanın kahramanı insanlara objektif olarak bakan, disiplinli bir kişi olarak tanıtılan Subay Drago, alışkanlıkları içinde kendini unutarak akıp giden zamana yenik düşen modern dönem insanını temsil etmektedir. Tatar Çölü moral bozucu olarak görülebilir ama onun yapmak istediği, modern yaşamdaki insana içinde yaşadığı hayatı göstermeye çalışmaktır. Tatar Çölü varolma cesareti gösterememenin bir ifadesi olarak insan deneyimindeki tekrarın doğasını anlama noktasında önemli unsurları içerir. Tatar Çölü bu yönüyle bir sorgulama, sorgulatma işlevine sahip bir roman olma özelliğini gösterir. Edebiyat kişinin sahip olduğu yoğun duyguların somut bir aracı olarak görev yapmaktadır. Burada işin içine estetik kaygı girince konunun anlaşılması daha kolay bir hal almaktadır. Varoluşçuluğun edebî olarak ifade edilmesinde J. P. Sartre, A. Camus, F. Kafka, F. Dostoyevski gibi isimlerin yanına Buzzati’yi ve onun özellikle Tatar Çölü’nü eklememiz gerekir. Biz de makalemizde Tatar Çölü adlı eseri varoluşçu düşüncenin temel kavramları olan umut, umutsuzluk, ölüm, yabancılaşma ve tekerrür kavramları ekseninde ele aldık. Sonunda insanı bu tür olumsuz ve kaygı verici duygulardan kurtaracak olanın sevgi olabileceğini belirttik. Zira yaşam biz onu sevdikçe anlam kazanır. Bunun felsefenin görece kavramsal ağır yapısından ziyade roman gibi düşüncenin estetik yönü ön plana çıkaran eserlerle daha anlaşılır bir formda sunulabileceğinin imkânını göstermeye çalıştık.

The oil sector and thus oil revenues play a fundamental role in the life of the Iraqi people, as they contribute about 70% of the gross domestic product, about 94% of the general budget resources, and 98% of the value of exports, and a simple look at those ratios shows that the Iraqi economy suffers from the dominance of the rentier or economic unilateral phenomenon. Because of the almost complete dependence on this sector for the conduct of life in general and the rest of the other economic activities , It is matched by the great neglect and the continuous marginalization of the role of other sectors (agricultural, industrial, and service), which led over time to the exacerbation of this phenomenon, causing chronic imbalances in the Iraqi economy, which pushed the direction of searching for strategies or scenarios based on clear scientific planning, which in turn leads to maximizing The productive capacities of the various economic sectors contribute to mitigating and reducing the rentier hegemony. The researcher adopted the descriptive analytical approach to reach a number of conclusions. The research also concluded with some proposals that he hopes will take their way to decision-makers and government departments in order to reduce this phenomenon towards the application of diversification mechanisms.

Nowadays, one of the major purposes of any company is to survive in the competitive business markets. This purpose would be achievable through improving and developing growth in most cases. Prior studies suggest that leadership is a vitally important factor in achieving growth in any company. Some researchers studied leadership topics as one of the significant motivations for developing and improving the growth of a company and agreed that understanding the role of leadership and its effect on the growth of the company is influential. In all countries, Information Communication Technology (ICT) companies are recognized as significant growth drivers by leaving considerable impacts on that. According to the literature, growth is a determining factor for the productivity of any company. Based on the literature of the ICTs, weak and insufficient leadership skills are considered as the main factors that cause failure in achieving the planned growth and development of ICT. Consequently, the goal of this study is to clarify how leadership affects the development of ICT enterprises.

Citrus fruits are among the priority crops for Uganda. Government has invested significant resources to boost citrus production due to their potential to increase household income, nutritional security and national exports. However, soil-borne pathogens are among several biotic-factors significantly constraining production. Whereas inorganic chemicals have been applied in the past, they have potential detrimental effects. Therefore, an experiment was conducted in the greenhouse of National Forestry Resources Research Institute (NaFORRI) at Kifu - Mukono in 2020-2021 to determine dominant soil and Citrus pathogens and test efficacy of different non-inorganic citrus pathogen control practices. A randomized complete block design with five treatments replicated thrice was used. The treatments included; hot water, heated wet-soil, fumigated soil, solarized wet-soil, and untreated control. A total of 30 Citrus seeds per variety were treated with sodium-hypochlorite-solution (1:7) before being sown. Soils from above treatments were cultured on Potato and Sabouraud-Dextrose Agar (PDA and SDA) and de Man, Rogosa and Sharp (MRS) agar. Results indicated that Aspergillus niger was the dominant soil-borne pathogen identified in pure cultures. Others included A. flavus, A. fumigatus, A. viridinutans, Penicillium chrysogenum and Fusarium oxysporum. Ranking based on scores in: cost-effectiveness, leaf-health, chlorophyll-intensity and general-health of seedlings revealed solarization (35) as most effective technique for managing soil-borne pathogens, followed by boiling (33), heating (31), untreated control (27) and lastly fumigation (26). Identified pathogens induce aflatoxins in Citrus and lead to great losses during post-harvest handling; they also cause root and fruit-rots. Solarization creates solar-radiation in a miniature greenhouse that kills pathogens. There is a need to study non-inorganic control practices of citrus pathogens under field conditions for improved yields in Uganda.
