Pathogens of stored apple fruits
Authors: Trkulja Vojislav , Bagi Ferenc
Published: December 2022

From harvest to market or use, apple fruits are stored in warehouses for a short or long time, during which they are often exposed to the attack of various pathogenic microorganisms. Although there are no precise data on the losses caused by various pathogens on stored apple fruits in our country, it is quite certain that they are large, both due to the often inadequate storage conditions and the fact that less attention is paid to the storage of the harvested fruits than to their production. The paper describes the characteristic symptoms of the 25 most important diseases of stored apple fruits caused by various pathogens, as well as an overview of other less signifi cant pathogens that can appear on apple fruits during their storage. The measures for their suppression are especially emphasized and elaborated, so that the economic losses caused by these pathogens, if not completely avoided, then at least reduced to a tolerant measure.
Natural enemies of wooly apple aphid Eriosoma lanigerum (Hemiptera: Aphididae) in apple production (Malus domestica)
Authors: Ivezić Aleksandar , Trudić Branislav
Published: December 2022

Wooly apple aphid Eriosoma lanigerum Hausmann, 1802 (Hemiptera: Aphididae) is a significant pest of apple. Modern agriculture rapidly favors biological protection of plants and the introduction of certain beneficial organisms is becoming an increasingly frequent and promising way to control agricultural pests. In addition, the trend of withdrawing numerous active substances from the market has triggered an increasing interest of the agricultural public for predator, parasitoids and pathogens in the control of E. lanigerum. The parasitic wasp Aphelinus Mali Haldeman, 1851 (Hymenoptera: Aphelinidae) is considered the most important natural enemy of the wooly apple aphid. Although the application of this parasitic wasp is widely present in the integrated apple production, many studies indicate that the effectiveness of A. Mali is significantly increased when this species is used together with other beneficial insects, primarily with certain predatory species. The latest research indicates the frequent commercial use of predatory species in the control of wooly apple aphid, primarily representatives of the families Syrphidae, Chrysopidae and Coccinellidae. Also, for the successful suppression of the wooly apple aphid, it is very important to determine the optimal strategy that will ensure the successful integration of applied predators and other natural enemies of this pest.
Economically important species of mite (Acari: Tetranychidae; Eriophyidae) in apple orchadrs
Authors: Ivanović Ivana , Petrović Aleksandra , Popović Aleksandra , Petrović Miloš
Published: December 2022

Under favorable environmental conditions, mites can represent a significant problem in apple production. Several types of mites are found on apples, only a few are of economic importance: Panonychus ulmi, Tetranychus urticae, T. turkestani and Aculus schlechtendali. All the mentioned species have a high reproductive potential, which in warm and dry conditions leads to a rapid growth of populations. The period of activity and feeding of mites begins in spring and lasts until autumn, and the most pronounced symptoms are noticeable during the summer months. Nutrition and leaf tissue damages cause chlorosis and/or necrosis, photosynthetic disorders, increased transpiration, defoliation, fruits remain small, lose quality and decline, so yield losses can be extremely large.
Management in preschool education and institutions
Authors: Mavrić Mina , Muratović Amela
Published: December 2022

Contemporary trends in education have stimulated the existence of numerous competences and skills among preschool institutions. For years, those competences and skills were not implied nor required as special with the goal to improve learning and to motivate the education and upbringing of children. Such circumstances especially require the management in education. The purpose is to organize the work in the best manner so that human and material resources in the institutions are applied in the most appropriate manner. The manager in preschool institutions take care about the planning, setting goals, work organization, assignment delegation, motivation and engagement of the employees as well as administrative and financial plans of the organization. Persons with such skills are needed in the institutions for earliest upbringing and education of the youngest. That is especially noticeable in the countries which are in the development and transition process, like the Republic of Serbia. The paper represents the importance of management in education, its benefits and requirements for its development. This paper also signals that many employees of the preschool institutions require managerial competences. The paper represents certain hurdles which may appear, as well as the flaws in the system of preschool upbringing and education which can be overcome successfully with the work of a manager. The constant cooperation and communication at all levels is emphasized.
The European Union and the development of agricultural policy
Authors: Hadžović Jasmina
Published: December 2022

Relevant financial literature has for decades recorded debates about the choice between active and passive portfolio management strategy. In order to enrich domestic literature in this field, the paper presents the basic characteristics of these strategies, at the same time pointing to their positive and negative aspects. The aim of the research is to answer the question of which of these portfolio management strategies is superior. By putting forward arguments in favor of and against the choice of active and passive portfolio strategy, it is concluded that neither strategy is perfect and that it is impossible to talk about the superiority of active or passive portfolio management, as both strategies and both portfolio management models contain equally serious shortcomings that prevent them from achieving superiority. Problem solution should be sought in the implementation of a hybrid portfolio strategy that simultaneously integrates benefits and alleviates the disadvantages of these strategies.
Sustainable halal food production: Locusta migratoria as unused potential
Authors: Šerifović Jasmina , Dugonjić Aldin , Šušnić Saša , Uršulin-Trstenjak Natalija , Haliti Sead
Published: December 2022

Growing world population, limited agricultural resources for food production and global pollution represent an imperative to find an alternative to conventional food production (primarily meat). In order to achieve this goal, it is necessary to establish a sustainable diet with a reduction in meat consumption and / or the use of alternative sources of protein. Locusta migratoria (locusts) are a species believed to be one of the oldest living things in the world. In some Islamic countries, they are used as food (e.g. Indonesia and Malaysia) and have untapped potential in Western countries. Grasshoppers represent a long-term sustainable solution due to significantly lower prices of cultivation and production, but also a much smaller impact on the environment (primarily greenhouse gas emissions and waste generation-zero waste). In addition to the positive impact on the environment, their nutritional values make them an attractive alternative (high content of protein, unsaturated fatty acids and minerals). The EU has recognized the potential for commercialization of alternative protein sources by approving Locusta migratoria as a novel food, safe for human consumption. Given the skepticism of Western consumers, the approval by European Member States is a turning point as it guarantees that locusts are a safe source of food for humans and that all legal provisions are in place to ensure quality and safety.
An empirical model for forecasting electric generation for nearshore energy potential in Thailand
Authors: Phaiboon Supachai , Phokharatkul Pisit
Published: December 2022

This paper presents electrical energy forecasting from near shore wave potential in the Gulf of Thailand using an empirical model. An electric generator was installed on the near shore to perform measurements and create an empirical model for predicting electric generation. In order to forecast the capacity of the electric generation from sea waves with sufficient electricity consumption, the household data in the Gulf of Thailand and the Andaman Sea were collected from the year 2012 - 2019 to forecast the increasing rate of the number of households in the five years period (2021-2025). Cost and payback period were analyzed in each location in order to invest the renewable energy generation.
Rutting prediction of hot mix asphalt mixtures reinforced by ceramic fibers
Authors: Al-Saad Ahmed , Ismael Mohammed
Published: December 2022

One of the most severe problems with flexible asphalt pavements is permanent deformation in the form of rutting. Accordingly, the practice of adding fiber elements to asphalt mix to improve performance under dynamic loading has grown significantly in order to prevent rutting distress and ensure a safe and long-lasting road surface. This paper explores the effects of a combination of ceramic fiber (CF), a low-cost, easily available mineral fiber, and thermal insulator fiber reinforced to enhance the Marshall properties and increase the rutting resistance of asphalt mixes at high temperatures. Asphalt mixtures with 0%, 0.75%, 1.5%, and 2.25% CF content were prepared, and Marshall stability and wheel tracking tests were employed to study the effect of added CF on asphalt mixture performance. Scanning electron microscopy (SEM) and field emission scanning electron microscopy (FESEM) were also used to investigate the morphologies of CF and reinforced asphalt mixtures and to identify the mechanism of improvement .According to the study results, the ideal ceramic fiber content was 1.5%, which yielded an improve in Marshall stability and reduced rut depth by 22.05% and 27.71% at temperatures of 50°C and 60°C, respectively, when compared to asphalt mixtures without CF. Microscopic analyses clearly revealed the surface properties, particle diameter size, and fiber distribution of the reinforced mixture, including the network structure and strength mechanism, which improved the performance of the asphalt mixture by forming a three-dimensional network.
Combined PIPRECIA method and modified FUCA method for selection of lathe
Authors: Trung Do , Truong Nguyen , Thinh Hoang
Published: December 2022

The choice of technological equipment in general or lathe in particular has a great influence on the efficiency of the machining processes. Lathes are often evaluated by many criteria, both quantitative and qualitative. Sometimes the criteria employed by the methods are opposite to each other. Hence the choice of lathe is usually made through the evaluation of multiple criteria, which is known as "Multi-Criteria Decision Making - MCDM". In the research was used PIPRECIA method to determine the weights of the criteria. Modifications to FUCA method were then implemented. The combination of PIPRECIA method and the modified FUCA method were applied to the lathe selection in two cases. In both cases the best and worst alternatives were determined in the same way as when using the CURLI method. This confirms the correct implementation of the FUCA method modification, and the combination of PIPRECIA and the modified FUCA method turns out to be a right approach in the selection of lathes. Details that need to be considered in future research were also mentioned in this study.
Between national memory and oblivion: Monuments to Heroes of the sword József Schweidel in Sombor and Karađorđe Petrović in Belgrade
Authors: Milovanović Jovana
Published: December 2022

The removal of monuments from the public space - commemorating vožd Karađorđe Petrović and General József Schweidel in Belgrade and Sombor respectively - followed by the subsequent physical dematerialization of the sculptural solutions, for example the repurposing of the Sombor plinth, points to a civilizational practice known as damnatio memoriae (condemnation of memory) that has existed for millennia. The manifestation of this practice can serve as a basis for analysing Hungarian-Serbian relations in the period of the Great War and its immediate wake. At the dawn of the 20th century, a cult of memory came to be formed around the national hero József Schweidel, one of the Thirteen Martyrs of Arad, the story of whose suffering grew over time to become an important topos in Hungarian national ideology. General Schweidel was born in Sombor at the end of the 18th century, and it was for this reason that, in 1905, a monument was erected to commemorate him in front of Sombor's County Hall. The responsibility for the creation of this work was entrusted to the Hungarian sculptor Mátrai Lajos György. The erection of the Schweidel monument was preceded by a multi-stage process of mythologizing the hero-martyr who laid down his blood for the life of the Hungarian nation. The first of these stages was a concerted effort to gather the General's personal belongings, viewed as 'relics', with this being followed by the unveiling of a memorial plaque at the location where the General's house had once stood; all with the aim of establishing a memory of the national hero within the community from which he came. Simultaneous to this, a tender was announced for the erection of a monument to the leader of the First Serbian Uprising on the site of Belgrade's Kalemegdan Park, which was awarded to Paško Vučetić. After numerous vicissitudes, the sculptural ornamentation, with Karađorđe at the summit, would finally be inaugurated as part of the ceremony to welcome the return of the Serbian Army from the Balkan Wars in 1913. However, both monuments would prove to be short-lived. Karađorđe's monument was probably demolished by Austro-Hungarian soldiers in the first months of the occupation of Belgrade, most likely in the autumn of 1915, while Schweidel's monument was removed from the city area in 1920 and completely destroyed some time after 1925. The final collapse of the Austro-Hungarian monarchy in the autumn of 1918 brought the realization of the concept of a Hungarian political nation to an abrupt halt, and opened the way for the rival ideological practice of creating and unveiling new, Yugoslav, symbols on the territory of former southern Hungary.
'Palata Beograd' in Belgrade
Authors: Andrejević Marija , Pavlović Marija
Published: December 2022

With its characteristic appearance and height, which had until that time not been seen in Belgrade - nor Yugoslav - architecture, architect Branko Pešić's unique construction, Palata Beograd, built between 1969 and 1974, paved the way for a new vision of the multi-storey buildings of the modern city. To date, Palata Beograd, popularly called Beograđanka, has not been the subject of any major scientific research, although it has remained a constant topic in the daily and popular press for many years, and has also been addressed as a case study among other constructions by researchers of post-war architecture. As the largest skyscraper in the region, having been executed in the aesthetics of International Style architecture, and the original work of a single author, it has been inscribed as a property under preliminary protection of the Cultural Heritage Preservation Institute of Belgrade, as representative of the legacy of its era and a reminder of prosperity and construction boom that characterized 1970s Belgrade. Half a century after its construction, the chronology of its origins and erection still testifies to the social, architectural and cultural significance of this building.

Introduction: The celiac trunk is an arterial trunk that has been the subject of numerous anatomical and radiological studies. From its origin, at the front of the abdominal aorta, the trunk extends for 1.5 - 2 cm and then divides into three branches: the left gastric artery, the common hepatic artery and the splenic artery. This type of trifurcation was first described by Haller, in 1756, and is considered the most common anatomical pattern. Anatomical variations of the celiac trunk are numerous, both in terms of branching and dimensions. The complete absence of the celiac trunk is a rare anatomical variation, wherein all three branches arise directly and independently from the abdominal aorta. Case report: A 63-year-old oncology patient was referred to the radiology department for an Mr examination of the abdomen, in order to differentially diagnose changes in the adrenal glands. During the examination, complete absence of the celiac trunk was observed. The left gastric artery, splenic artery, and common hepatic artery arose directly and independently from the abdominal aorta. Conclusion: A variation of this type is mostly asymptomatic and has no negative effect on the blood supply of visceral organs. In literature, the prevalence of this vascular pattern ranges from 0.1% to 4%. Knowledge of vascular variations in the abdomen is very important during surgical, diagnostic and endovascular procedures.

Published: December 2022

Neurosarcoidosis is a relatively common extrapulmonary form of sarcoidosis. It is characterized by variable clinical presentation, low probability of spontaneous remission, and significant impact on the quality of life, as well as potential increase in mortality. In addition to corticosteroids, other drugs are used in the treatment of neurosarcoidosis, such as methotrexate, azathioprine, mycophenolate mofetil, tumor necrosis factor a (TNF-a) inhibitors, infliximab and adalimumab. In this paper, by reviewing the available literature, we have attempted to consolidate the current knowledge and novelties in the treatment of neurosarcoidosis, for the purpose of assisting physicians in their day-to-day clinical work. Previous studies still favor pulsed doses of corticosteroids, while other forms of therapy have proven beneficial only in individual cases. However, it should be noted that additional research is needed in order to successfully develop individual therapy.
Hydrodynamic Decomposition-Based Optimization of Ship’s Hull–Propeller System Under Multiple Operating Conditions
Authors: Zakerdoost Hassan , Ghassemi Hassan
Published: December 2022

_

In this research, a framework for the analysis and design optimization of ship hull–propeller systems (HPSs) in waves is developed. This framework can be utilized as an efficient synthesis tool to determine the main geometric characteristics of the HPSs during the early stage of ship design. The optimization is carried out in two levels and under multipoint operating conditions (OC). Multiobjective evolutionary algorithm based on decomposition (MOEA/D) as an efficient multiobjective evolutionary algorithm, Michell integral and OpenProp tool as low-fidelity hydrodynamic solvers and boundary element method (BEM) as medium-fidelity solver are applied on two case studies to minimize the effective power and maximize the propulsive efficiency of HPSs. To estimate the added wave resistance, an efficient semiempirical formula is also employed. The Series 60 hull form with DTMB P4118 single propeller and S175 hull form with KP505 twin-propeller are considered as the original models. The numerical results show that the framework can find optimized designs with better hydrodynamic performance.

Introduction

Optimizing the hydrodynamic performance of ships’ hull and propeller(s) based on multiple design condition has gained considerable importance over the last few years. High fuel oil costs are the reason that shipyards and ship owners are now focusing more than ever on the reduction of effective power and propulsive efficiency. Hydrodynamic performance parameters, such as effective power and propulsive efficiency, are determined by the hull form and propeller shape, so it is very important to choose a hull–propeller system (HPS) with good performance in early stage ship design.

There exist two main factors in the hydrodynamic design optimization of marine systems. The first factor is simultaneously considering all components of the system influencing objective function(s) and the second one is selecting a less time-consuming solver with satisfactory accuracy. In the ship design process, these two factors must be taken for conducting a reasonable optimization into consideration.

İntroduction and aim: Cancer affects people psychologically and organically. The emotional state of cancer patients is fragile and can be affected by many factors. We aimed to evaluate the effect of the Covid-19 pandemic on the mood and behavioral changes of cancer patients with solid cancer who are in follow-up and treatment.

Material and Method: A face-to-face questionnaire was filled in solid cancer patients without known psychological disorders who applied to the Medical Oncology outpatient clinic between 1-30 September 2021. The Hospital Anxiety and Depression Scale (HADS) and the scale examining the perspectives on Covid-19 were applied to the patients whose consent was obtained.

Results: A total of 235 people, 139 women and 63 men, participated in the survey. In the review of 202 completed surveys, the median age was 55 (23-83 years). In the study in which seventeen different solid cancer patients were evaluated, breast (52.5%), colon (19.3%) and lung (10.8%) cancers were most common. Most of the people who were more afraid of Covid-19 compared to cancer were patients who were on active cancer treatment. In the multivariate regression analysis, being on active treatment was found to be the only risk factor for 'being more afraid of Covid-19' compared to cancer. During Covid-19 pandemic, it was observed that 18 (8.9%) patients delayed their treatment/follow-up due to fear of Covid-19 infection. A high HADS anxiety score was observed in 58 (28.7%) patients, and a high HADS depression score was observed in 39 patients (19.3%). Conclusion: Cancer patients are seriously worried about the progression of their cancer due to changes in follow-up or treatment due to Covid-19 pandemic. However, despite the associated risks, they were found to want to continue their treatment as planned.
¿Son éstos tiempos de peste?
Authors: Alvar Jorge
Published: December 2022

Las pandemias han existido desde los albores de la Humanidad como resultado del espacio que se comparte entre microorganismos y el propio humano. Una serie de determinantes, como la pobreza, la ignorancia y la falta de higiene las favorecieron entonces y, hoy, esas circunstancias siguen dándose en muchos países. En el presente estudio se repasan tres pandemias para ejemplarizar las causas de entonces —también los éxitos— y poder reflexionar sobre los motivos de las pandemias actuales. Pero, además, en este momento se unen otros motivos que las favorecen, como la superpoblación, la agresión del medioambiente y la rapidez de los viajes internacionales. La magnitud de estos nuevos determinantes han llevado al cambio de era geológica en pocos miles de años habiéndose abierto paso el Antropoceno. Sus consecuencias se pueden analizar enfermedad a enfermedad pero para los estudiosos se debe entender como un todo, un cambio de paradigma en lo que entendemos como salud y que derivará en consecuencias impredecibles si no se toman medidas a tiempo.

La gamificación en ELE: un análisis de la motivación según la TAD
Authors: Villa Jiménez Natalia
Published: December 2022

Resumen: El presente artículo analiza la gamificación como técnica metodológica que fomenta la motivación en el aula de español como lengua extranjera (ELE). En primer lugar, partiremos de los preceptos propuestos en la teoría de la autodeterminación (TAD) desarrollada por Ryan y Deci (1985). En segunda instancia, abordaremos las dinámicas, las mecánicas y los componentes que pueden constituir una práctica gamificada. Finalmente, tomando como referencia los postulados desarrollados en la TAD, centraremos nuestra atención en la manera en la que el diseño de un sistema gamificado puede incentivar un comportamiento regulado extrínseca o intrínsecamente.
Palabras clave: gamificación, TAD, motivación, ELE.

El desarrollo del hidrógeno: estrategias y políticas en Europa y España
Authors: Escribano Gonzalo , Lázaro Lara , Urbasos Ignacio
Published: December 2022

El desarrollo del hidrógeno como vector de la descarbonización se ha convertido en un tema de actualidad en el debate energético y económico, tanto europeo como global. Ese interés se ha visto reforzado por la crisis energética europea causada por la invasión rusa de Ucrania, que junto con el imperativo de la descarbonización ha supuesto un impulsor adicional. Este artículo aborda las estrategias y políticas europeas para impulsar el hidrógeno, con foco en sus implicaciones para el caso español. Para ello, se exponen primero de manera somera las características económicas del hidrógeno y sus diferentes tipos, así como las tendencias más destacadas sobre su desarrollo. A continuación, se comparan los principales rasgos de las estrategias europeas de hidrógeno, tanto en el plano nacional como en su modelo de inserción internacional, concluyendo que las divergencias existentes constituyen un obstáculo para la integración de los mercados y por tanto para su despliegue. A continuación, se analizan las políticas españolas de promoción del hidrógeno verde, tanto a nivel nacional como regional, incluyendo la reciente actualización de la Hoja de Ruta presentada por el gobierno español. El artículo concluye que las estrategias de los Estados miembros no son totalmente consistentes y entrañan el riesgo de fragmentar el mercado europeo en mercados nacionales.
Los efectos fiscales de destopar las contribuciones a la seguridad social: implicaciones para la reforma de las pensiones en España
Authors: Elias Ferran , Riudavets-Barcons Marc
Published: December 2022

En este artículo estimamos los efectos fiscales del destape de las cotizaciones a la seguridad social en España. Este ejercicio no es trivial porque no hay datos públicos disponibles sobre salarios por encima del nivel máximo de cotización. Sin embargo, en 2019 una reforma aumentó el tope cerca de un 7% y reveló parcialmente la forma de la distribución para los trabajadores con salarios altos. Explotamos esta variación y mostramos que el destape podría aumentar los ingresos de la seguridad social en un 0,22% del PIB. A continuación, discutimos las implicaciones de esta estimación para la reforma de las pensiones. Combinado con un aumento en las tasas de contribución de 0,6 puntos porcentuales (Mecanismo de equidad intergeneracional) y una regularización de los inmigrantes indocumentados, los ingresos totales recaudados podrían pagar el 44 % del aumento esperado en el gasto de pensiones para 2030.

Published: December 2022

Thanks to the in silico approach in drug design, the identification of new molecules is enabled and facilitated, as well as the optimization of the pharmacokinetics and toxicity of compounds obtained from different sources. Chromatographic methods, on the other hand, provide accurate and reliable information on the influence of the nature of substituents and applied organic modifiers on the pharmacological behavior of compounds, relying on the existence of similarities between intermolecular interactions that determine compound behavior in biological and chromatographic media. Barbituric acid derivatives were subjected to QSRR analysis and the parameters obtained by reversed phase thin layer chromatography (RP TLC18 F254s) were correlated with selected software-derived predictors of permeability, pharmacokinetics and toxicity using the method of linear regression. Тhus satisfactory mathematical models were obtained.

Published: December 2022

This article is devoted to digitalization in agrarian law as one of the important branches of jurisprudence. Along with other branches of law, agrarian law contributes to the life of the state. In this regard, the purpose of the scientific work, this scientific essay, is to further study the relationship between the designated branch of Russian law and these modern technologies, which are not only the Internet, but also various programs, legal reference systems, and other similar products of human activity. Based on the objectives, the author in this text provides an analysis of the methods of application of these technologies, shows their role in the functioning of local rural administrations as important links in the agricultural sector. Since the agricultural sector is not only directly objects where agricultural products are produced. Among them are fields, gardens, farms, summer cottages, meadows and other objects. These are also the territories where the rural population lives, the authorities that manage these territorial entities. In addition, the relevant relations where digitalization is involved are analyzed. This is, in particular, municipal service in rural authorities. In general, the essay gives an appropriate idea of the mechanism of application of digital technologies in the agrarian law of the branch of Russian law, aims at further analysis of relations in these areas of human activity, which in the future will bring the necessary fruits.
Mechanism of Legal Regulation of Agricultural Production Insurance as a Way to Ensure Food Security of the Country
Authors: Isakov Aleksandr Nikolaevich
Published: December 2022

The article talks about the importance of agricultural insurance for ensuring the financial well-being of agricultural producers and food security of the country. The main regulatory documents regulating insurance in the agricultural sector of the economy are indicated. The positive aspects achieved during the validity period of Federal Law No. 260 are noted: the possibility of choosing the most significant risks for production and the exclusion of unlikely ones; the ability to establish a real level of coverage; the threshold for the death of the crop yield and the harvest of perennial plantings has been abolished and the introduction of a criterion - a decrease in the actual harvest compared to the planned and loss of viability of perennial plantings as a result of the occurrence of events provided for by law; it is possible to take into account the specifics of the economy when assigning insurance amounts; the range of deductibles has been expanded; it is now possible to conclude an insurance contract for at least 70% of the cost crop yields, plantings of perennial plantings, or animals; the possibility of using space monitoring data to confirm the facts of the occurrence of an insured event. Production insurance has been introduced in case of natural emergencies. A number of issues requiring additional legal regulation in connection with the occurrence of natural emergencies are considered. The analysis of the law enforcement practice on agricultural insurance in the country is given.

Wetland condition assessment is often performed by land managers, federal and local governments, and conservation organizations to document current condition and potentially take action to protect or restore valuable wetland resources. These condition assessments often include data collection or surveys of biotic communities such as vegetation, macroinvertebrate, and amphibian communities. Assessment tools for gauging quality of these communities are needed to allow scientists to understand overall condition. To facilitate a better understanding of amphibian communities found in wetlands and associated habitat quality, we created ratings of anthropogenic disturbance sensitivity for wetland and aquatic amphibian species in North Carolina. With adequate surveys of amphibian communities, these ratings can be input into an index of amphibian wetland habitat quality for North Carolina wetlands, the Amphibian Quality Assessment Index (AQAI). Comparison of the AQAI against amphibian species richness in a 3-yr study in 16 wetlands showed the two indices to be correlated but not strongly so. The AQAI has the advantage of providing additional habitat quality information beyond indices based solely on species richness and abundance.

Authors: Celi Simbaña Stalin Santiago , Andrade Mora Diego Sebastián , Mendoza Benalcázar Jessica Estefania
Published: December 2022

Introduction: Accessory spleen, also called supernumerary spleen, is a generally benign and asymptomatic condition, characterized by the location of splenic tissue outside the spleen. Its prevalence has been reported between 10% to 30% of the population. Materials and Methods: Patient evaluated for recurrent urinary tract infection in which a computed tomography urography without contrast was requested, incidentally finding an accessory spleen.
Results: Clinical case report and diagnostic imaging challenge.
Conclusions: The accessory spleen is a condition of congenital origin, relatively frequent for which it should be considered in the spectrum of the differential diagnosis of acute abdomen and intra-abdominal masses since its timely diagnosis can avoid unnecessary surgeries.

Authors: Sartori Junior Zilio , Teixeira Eduardo Kunzel Teixeira , Duarte Ana Márcia Debiasi , Basso Carla de Almeida Martins
Published: December 2022

O objetivo deste trabalho é caracterizar a produção da literatura científica internacional que relaciona estudos do SC em “Startups”. Como metodologia, realizou-se um estudo bibliométrico por pesquisa descritiva e coleta de dados. A amostra foi baseada na base de dados Scopus, totalizando 85 documentos selecionados para análise. Startups são consideradas empresas nascentes de base tecnológica, que atuam em um ambiente de incertezas, buscando tornar seu modelo de negócio repetível e escalável. Assim, o SC é um meio importante para coordenar o processo operacional (ciclo de vida) de startups (Walley, 2007; Rusko, 2011).  Os resultados demonstram, além de diversidade quanto a autoria dos trabalhos,  dois campos a priori de pesquisa. Um com olhar sobre o impacto das restrições financeiras, principalmente em empresas iniciantes, na coordenação da cadeia de suprimentos. O outro, com um olhar sobre a orientação empreendedora e modelo de negócio. O estudo contribui na compreensão da necessidade da busca de mais teorização e exploração da SC dentro do domínio de Startups. Na prática, esta necessidade reflete na premência de empreendedores e gerentes melhorar a sobrevivência e desempenho de startups, gerenciando ativamente suas cadeias de suprimentos.
La autonomía universitaria en Chile: entre el Estado y el Mercado (1981-2020)
Authors: Henríquez Ramírez Alfonso , Isla Aguilera Matias , Montero Barriga Violeta , Salazar Vergara Leonardo
Published: December 2022

El presente artículo desarrolla una discusión conceptual y jurídica de la autonomía universitaria y su aplicación en Chile a través de la distinción y análisis de tres periodos de reforma en materia de educación superior desde el 1981 a 2020. La contribución central de este estudio es incluir en su análisis una nueva etapa de reforma (Ley N° 21.091) que cambia profundamente tanto la normativa como las instituciones que rigen a los centros de educación superior y, hasta el momento, no ha sido explorado por parte de la literatura especializada. Se concluye señalando que aun cuando se han generado transformaciones significativas en el funcionamiento del sistema de educación superior, es posible identificar elementos comunes que han persistido como eje orientador. El texto pertenece a los estudios sobre derecho y ciencia política y metodológicamente utiliza la revisión bibliográfica y normativa para analizar las trayectorias ya mencionadas y su impacto en la institucionalidad y devenir nacional. Finalmente, el texto presenta claves históricas en un momento de discusión nacional e identifica nudos críticos a profundizar en investigaciones futuras.
Algunas sentencias de la Corte Suprema que abordan conceptualmente el Derecho de la Libre Competencia
Authors: Marmolejo Crispulo
Published: December 2022

En el diseño institucional chileno, la Corte Suprema desempeña un rol destacado en el proceso de revisión de las sentencias del Tribunal de Defensa de la Libre Competencia (TDLC). El objetivo de este trabajo consiste en analizar brevemente ciertas opciones conceptuales empleadas por la Corte Suprema de Chile, en la fundamentación de algunas de sus sentencias, respecto de la disciplina del Derecho de la Libre Competencia. Para lograr este objetivo, se han analizado 105 sentencias pronunciadas por el máximo tribunal chileno, contenidas en el repositorio de jurisprudencia del Tribunal de Defensa de la Libre Competencia, pronunciadas entre los años 2005 y 2021. En 73 de esas sentencias, no se han hallado propuestas de alguna conceptualización sobre la disciplina del derecho de la Competencia; vale decir, el juzgador no ha estimado conveniente citar una definición de esta área del derecho, particularmente en la parte considerativa de dichas decisiones, al contextualizar el ámbito de aplicación del derecho de la competencia. Sin embargo, en las 32 sentencias restantes, la Corte Suprema optó por incluir en su fundamentación algunas propuestas de conceptualización sobre la disciplina, o bien esclarecer nociones técnicas propias de esta área del derecho. En la evolución de sus fallos, particularmente desde 2012, se observa que la Corte Suprema ha ido complejizando su razonamiento jurídico en materias de esta disciplina, desarrollando fundamentaciones más extensas, clarificando conceptos técnicos y optando por establecer ciertas definiciones acerca de la disciplina del Derecho de la Libre Competencia.
Intermittent Manually Controlled versus Continuous Infusion of Propofol for Procedural Sedation during Interventional Endoscopic Procedures: A Single-blinded Randomised Study
Authors: Haher Ramandeep Kaur , Heera Bhupinderjeet Singh , Mehta Harjinder Kohli, Ritul
Published: December 2022

Introduction: Sedation with propofol during interventional gastrointestinal endoscopy is usually accomplished with two main modes-intermittent manually controlled using a syringe, and continuous infusion using an infusion device. Aim: To compare the effect of bolus administration and infusion of propofol on recovery profile during sedation in patients undergoing interventional endoscopy procedures. Materials and Methods: The present study was a singleblinded randomised study in which 120 patients, belonging to American Society of Anaesthesiologists (ASA) grade I and II, of either gender, and age 18-70 years, were randomly assigned to receive intermittent bolus (Bolus Group, BG) or continuous infusion (Infusion Group, IG) of propofol sedation after induction with 2 mg Midazolam for deep sedation. BG patients received an initial dose of propofol, 1%, according to body weight (<60 kg: 40 mg, >60 kg: 60 mg), followed by boluses of 10- 20 mg adjusted to maintain a Modified Observer’s Assessment of Alertness /Sedation Scale (MOAA/S) of 0 or 1. In the IG, continuous propofol infusion (4-6 mg/kg/hr) via Graseby 2000 (Smiths Medical) was administered after a bolus of 1 mg/ kg of propofol. Vital signs, recovery time, quality of recovery, total dose of propofol, side-effects as well as patient and endoscopist satisfaction score were evaluated. The data was compiled systematically and analysed using unpaired Student’s t-test and Chi-square test. The p-value <0.05 was considered significant. Results: The demographic profile of patients was comparable in both the groups. The recovery time (6.30±2.06 minutes in BG versus 5.71±2.19 minutes in IG) and total propofol dose (327.74±45.52 mg in BG versus 314.46±64.52 mg in IG) were comparable. Similarly, the quality of recovery was identical in both groups. At 10 and 15 minutes after induction, arterial blood pressure was significantly lower in group BG as compared to group IG (114±16.96 in BG versus 120.34±8.78 in IG; p-value=0.031). The endoscopist’s satisfaction score was better in IG (p-value=0.001), whereas, the patient satisfaction score was comparable in both the groups (p-value=0.162). Conclusion: Both regimes allowed good controllability of propofol sedation. However, endoscopist satisfaction score was significantly better and haemodynamic fluctuations were less in infusion group.
