Alfisols have low fertility, so fertilization is carried out to increase soil fertility and support the growth of maize plants. The continuous use of inorganic fertilizers in high quantities can cause land degradation, so it is necessary to reduce the amount by adding other fertilizers, such as organic fertilizers, as well as the relatively high price of inorganic fertilizers. This research was aimed to examine the potential of organic fertilizers in replacing inorganic fertilizers. The experimental design was a completely randomized block design with nine combination treatments of organic and inorganic fertilizers with three replications. The results showed fertilizer treatment ½ NPK + 1 PO affected and increased levels of organic C, CEC, base saturation, total N, and available P in Alfisols and maize yield. However, it did not significantly affect pH, base saturation and available S in Alfisols. The chemical properties of the soil had increased values ​​of 48%, 9.01%, 61.3%, and 134.5%, respectively. The treatment of ½ NPK + 1 PO increased maize productivity by 47.76% compared to the control with the productivity of 12.7 t ha-1, which the results were not significantly different from standard NPK. Thus, the application of 10 t ha-1 of organic fertilizer has the potential to replace ½ doses of inorganic fertilizer.

Authors: Ramírez Montañez Julio Cesar , Sarmiento Suarez Jaime Enrique , Suarez Quintero Alejandra 
Published: January 2023

La Alianza del Pacífico es un acuerdo de integración entre Colombia, Chile, Perú y México que se concreta desde el año 2012, cuyo propósito es aumentar la interdependencia entre los países, con mayor cooperación entre sí. El objetivo de esta investigación es presentar los asuntos más relevantes del comercio intrarregional de las partidas arancelarias con mayor dinámica en las exportaciones e importaciones del departamento de Santander, en el periodo 2020-2021, con los países miembros de la Alianza del pacifico. La metodología implementada fue de carácter exploratorio y descriptivo. Dentro de los hallazgos más representativos se puede destacar el bajo nivel de intercambio comercial en las exportaciones e importaciones que llevan a cabo entre Santander y los países de la Alianza del Pacífico. De igual manera, se pudo constatar que los principales productos de exportación de Santander hacia la Alianza del Pacifico son los Carburo reactores tipo gasolina para reactores y turbinas, siendo México el principal socio comercial en la dinámica tanto importadora como exportadora del departamento, observándose una mayor participación de las exportaciones correspondientes al sector metalmecánico, donde los conductores eléctricos para una tensión inferior a 1000 V de cobre es el principal producto importado desde los países de la Alianza del Pacifico. Se pudo determinar de igual forma que México es el principal proveedor de bienes y servicios desde la Alianza del Pacifico.
Modernidad, modernización, y su convergencia. Un marco teórico, conceptual y operativo para investigar el cambio en sociedades en transición
Authors: Villamarín Martínez Francisco Javier 
Published: January 2023

El propósito del artículo consistió en realizar una revisión de algunas de las definiciones de Modernidad y Modernización y de las propuestas de su convergencia, con el fin de guiar los estudios de estos procesos en sociedades particulares, como las de América Latina, en las que desarrollo y atraso coexisten generando conflictos y desigualdad.

Se revisó las teorías de algunos autores contemporáneos especialmente de la sociología, así como las reflexiones de científicos sociales latinoamericanos provenientes de diferentes disciplinas, como la economía. Los criterios elegidos para seleccionar estas fuentes se soportaron en su riqueza explicativa y en la gama de indicadores que ofrecen para identificar e investigar la particularidad del cambio.

La revisión mostró que en las definiciones operativas de la modernización y en la manera como se manifiesta la superación de las tensiones entre este proceso de cambio y la modernidad se encuentran dimensiones e indicadores para investigarlos, analizarlos y caracterizarlos en este tipo de sociedades. También arrojó que las definiciones contemporáneas ofrecen una explicación limitada de su dinámica que mixtura diferentes velocidades y ritmos en un mismo tiempo y espacio.

Objective. To study the features of invasive aspergillosis (IA) due to A. non-fumigatus versus A. fumigatus in adult (≥ 18 years) recipients of allogeneic hematopoietic stem cell transplantation (allo-HSCT) in 2016-2021. Materials and methods. The study included 33 patients with IA caused by A. non-fumigatus (n = 20) and A. fumigatus (n = 13). A comparative analysis of cases of IA, the results of therapy and outcomes in patients after allo-HSCT in the RM Gorbacheva Research Institute was performed. Diagnostic criteria EORTC / MSGERC 2020 were used. Results. Invasive aspergillosis caused by A. non-fumigatus made up the majority (60.6 %) of IA cases with an identified pathogen registered in patients after allo-HSCT in the period from 2016 to 2021. The main etiological agents in the A. non-fumigatus group were A. niger in 13 (65 %) patients, A. flavus – in 4 (20 %). The median day of diagnosis of A. non-fumigatus IAwas + 110 days (17–2093), for A. fumigatus it was + 46 days (2–866) (p = 0.171). Overall 12-week survival was 55 % and 59.2 % in the A. non-fumigatus and A. fumigatus groups, respectively (p = 0.617). The majority of patients in both the A. fumigatus (n = 10, 77 %) and A. non-fumigatus (n = 16, 80 %) groups received voriconazole as initial antifungal therapy. Second-linetherapy was required in 2 (10 %) patients with A. non-fumigatus IA: liposomal amphotericin B and echinocandins with or with-out posaconazole, and 2 (15 %) patients in the A. fumigatus group: liposomal amphotericin B and voriconazole in combination with echinocandins. A comparative analysis showed that in patients from the two groups, none of the assessed signs (gender, age, underlying disease, disease status at the time of transplantation, time from diagnosis to allo-HSCT, source of hematopoietic stem cells, conditioning regimen, donor type, antifungal prophylaxis, cytomegalovirus reactivation, severe acute and chronic graft-versus-host disease) did not differ significantly. Conclusions. A. niger is the main causative agent of IA caused by A. non-fumigatus. Patients characteristics, their treatment and outcomes did not differ significantly between the A. non-fumigatus and A. fumigatus groups.

Published: January 2023

Research background: The services provided by ecosystems are the main support for human populations and for the development of any type of activity. Today, the provision of these services is under threat. The economic valuation of ecosystem services is vital to design appropriate policies, define strategies and manage ecosystems.
Purpose of the article: The objective of this study is to analyse the evolution of research on the economic valuation of ecosystem services over the last two decades. More specifically, it aims firstly to identify the main agents driving research and, secondly, it seeks to synthesize in a single document the relevant information on the main economic valuation methods, relating them to the categories of services, ecosystems and regions where they have been employed.
Methods: A quantitative review was first carried out through a bibliometric analysis to identify the main drivers of this line of research and its development trends. Secondly, a qualitative review was conducted through a systematic review focusing on the most commonly used valuation techniques in relation to the characteristics of the service, the geographical scope and the ecosystem analysed.
Findings & value added: The main novelty of this work, compared to previous literature, is that the relationship between the study area, the type of ecosystem, the category of service and the economic valuation methodology are analysed for the first time. The results highlight the need to continue expanding knowledge in relation to the temporal and spatial scale in the economic value of ecosystem services, the subjective nature of the estimates and the heterogeneity between the different social sectors with respect to the benefit obtained.

Authors: Mulugeta Sintayehu Musie , Gosztola Beáta , Radácsi Péter 
Published: January 2023

SummaryIntroduction:Drought stress is known to change biochemical activities resulting in altered plant growth and development.Objective:Due to the shortage of research evidence in a certain taxa of basil, it is imperative to examine the relationship between drought stress and morphological changes as well as essential oil accumulation.Methods:An open field experiment was conducted in 2020 to determine the effects of drought stress on the morphological and biochemical responses of selectedOcimumspecies. Five basil species, namelyO. basilicum‘Genovese’,O. basilicum‘Ohre’,O. × africanum,O. americanum,O. selloi, andO. sanctum‘Krishna’ were grown under irrigated (control) and non-irrigated (drought stress treatment) plots with two block replications.Results:The result showed that irrigation had a positive effect on production. Consequently, fresh and dry biomass yields were higher on irrigated plots by 39% and 33%, respectively. No significant changes were detected between the treatments in essential oils (EO) yield and EO composition of major compounds. However, a slight increase in camphor (O. × africanum), nerol (O. americanum), and trans-β-caryophyllene (O. sanctum‘Krishna’) ratios were observed under irrigation treatments. On the other hand, drought stress increased EO content, polyphenol content, and antioxidant capacity. Furthermore, drought stress had a positive effect on the ratios of 1,8-cineole (O. × africanum), and eugenol (O. sanctum‘Krishna’). There is only a slight increase in EO content under drought stress, which is not comparable to the significant yield reduction recorded. Morphological and biochemical variations were also detected among basil species. Accordingly, higher biomass (616.33 g/plant) and EO yield (3.72 ml/100 g) among the species were obtained fromO. basilicum‘Genovese’ andO. × africanum, respectively.Conclusion:Irrigation is imperative for maximizing biomass and EO yield of tested basil species.
The Use of Newly Synthesized Composite Scaffolds for Bone Regeneration - A Review of Literature
Authors: Stevanovic Momir , Vujovic Sanja , Stanisic Dragana , Desnica Jana , Ognjanovic Irena 
Published: January 2023

Abstract
Bone tissue engineering is a multidisciplinary concept that combines biological and engineering principles to repair bone defects. Three elements that have a fundamental role in bone tissue engineering are scaffolds, stem cells, and bioactive components. Scaffolds mimic extracellular matrix functions and provide mechanical support for the new tissue formation. They are made of different natural and synthetic materials that can be categorized into three main groups: ceramics, metals, and polymers. Among them, synthetic polyesters and their combination with bioceramics, have been the most frequently used for scaffold fabrication. They could be potentially applied in clinical practice in the future as an alternative to the standard use of bone grafts but more studies are needed to assess their performance in the challenging conditions of human bone defects.

Abstract
At present, clamping of the portal triad is a widespread surgical procedure in hospitals. Such an operation can prevent pathological changes in the organs. However, the optimal time for clamping remains unclear. To determine the starting time of irreversible morphological changes in the small intestine due to the clamping of the portal triad. The study was carried out on rats (n=94). Animals were randomly subdivided into 4 groups based on the duration of clamping of the portal triad (PT): I control group (CG; without clamping the PT; n=10); II intervention group (6-IG; clamping PT for 6 min; n=28); III intervention group (12-IG; clamping time of the PT for 12 min; n=28); IV intervention group (24-IG; clamping time of the PT for 24 min; n=28). In groups 6- IG, 12-IG, 24-IG, after clamping the portal triad, animals were withdrawn from the experiment after 3 hours, 6 hours, 12 hours, 1 day, 3 days and 7 days. Morphological changes in the small intestine were assessed by measuring the diameter of the lumen of micro-vessels. In addition, the mortality in the groups was analysed as well. In the CG group, the diameter of the arterioles of the small intestine was 34±4 μm, the diameters of pre-capillaries were 15±2μm, the capillaries were 5.4±1 μm, the post-capillaries were 18±2 μm, and the diameter of the lumen of the venues was 40±3 μm. In the 6-IG group (on the 3rd day), the structure of the small intestine showed the recovery signs. By the 7th day, the indicators returned to their original values. In the 12-IG group, the parameters of the small intestine were restored on the seventh day that corresponds to the usual course of the disease. However, in the 24-IG group, changes in these organs persisted until the end of the study. No deaths were reported in the CG and 6-IG animal groups. Mortality among rats of the 12-IG group was 14.3%, while in the 24-IG group with PT clamping for 24 minutes it was 42.8%, respectively. The morphological changes in the microvasculature of the small intestine after 6-minute PT clamping showed a tendency to recover (back to the control parameters). Nevertheless, after 24 minutes of clamping, the changes in the intestinal tissue were irreversible.
